FAQ and Mods List

Hi friends, at the moment, this whole list (besides Mizuno16craft to the best of my knowledge) is Java only but I will be adding more Bedrock stuff in the future! Also, adding the links as I have the time/energy to do so!

1.12.2 Mods (Forge Mod Loader)

This is what I refer to on stream as Modded Minecraft!

Chisels and Bits

Cocricot

Decocraft

Flat Colored Blocks

OptiFine

World Edit

These mods also have "dependencies" needed to work, so you will also need to install PTRLib & Just Enough IDs to get these mods to work. If you have a low spec computer, I would recommend choosing between Cocricot and Decocraft, and skipping Flat Colored Blocks. Also, IMO don't add Flat Colored Blocks to your world if you aren't using Chisels, it is absolutely not a necessity at all.

1.17.1 Mods (Fabric Mod Loader)

Optifine

Optifabric (needed to make Optifine work on Fabric)

Replay Mod (for cinematics, and 3rd person POV)

WorldEdit Mod

If you are planning on using Replay Mod on Optifine (devs recommend Sodium+Iris), you need optifabric 1.11.20, optifine G9 mod and replay mod 2.6.1 (other combinations might not work)

1.19 Mods (Fabric Mod Loader)

I know it is a lot of mods, however, they all serve a purpose for me. Feel free to leave out what you don't want!

Must Haves

Sodium- Rendering engine and Optimizing (250% to 500% boost in FPS)

Iris Shaders- Open-source shaders mod that allows you to toggle your shaders with a single keypress. Super quick to update when new versions come out.

WI Zoom- Adds a Zoom key that allows you to use your mouse wheel to zoom in and out. Similar to the OK Zoomer mod which is no longer usable on Fabric as per 1.19. (Works with Optifine or Sodium)

Cull Leaves- adds "smart" leaves to Minecraft without Optifine (performance boosting!)

Lazy DFU- fixes an overengineered but mostly unused feature of Minecraft to have less wasted resources (saves at least 9 seconds when converting worlds to newer versions)

Mod Menu- adds an in-game menu allowing config editing in game

Optifine Parity

LambDynamicLights- Adds dynamic lighting to Minecraft

Capes- adds the ability to use capes from Optifine, LabyMod, and the MinecraftCapes Mod

CIT Resewn- Reimplements MCPatcher's Custom Item Textures, exactly the same as Optifine's CIT as it was adapted from the same source

Continuity- adds connected textures to Minecraft, supports Optifine's texture formats

Animatica- Reimplements MCPatcher's Animated Texture format, works perfectly with optifine's textures.

Transparent- Allows resource packs to have transparent entities.

Content Creation Tools

WorldEdit- a Minecraft map editor that lets you mass place, delete and manipulate blocks

Replay Mod- Adds the ability to record your gameplay and film it in a separate perspective.

Time Changer- Lets you change the client side time in Minecraft

Client-side Visual Mods

Illuminations- adds beautiful ambient particles like fireflies, chorus petals, prismarine crystals, and more (client-side)

3D Skin Layers- a client-side mod that 3D renders the second layer of skins

Falling Leaves- Adds very beautiful falling leaves to Minecraft & modded trees

Xaero's World Map- Adds a fullscreen map to your Minecraft world!

Dependencies

Cloth Config- Make sure you get the fabric install, Required for Falling Leaves

Fabric API- Required for Xaero's World Map, WI Zoom, LambDynamicLights, Capes, Mod Menu

Fabric Language Kotlin- Required by Capes,

Indium- Required for Continuity

Other Mods

Optifine alternatives

Modifiable Controller Support Mod

Shaders

To use shaders, you need to have stand-alone optifine or a mod loader like Fabric or Forge with Optifine or Sodium + Iris.

BSL Shaders - most seen on my streams, its a cool toned shader

Complementary Shaders- BSL edit, best option for survival, brightens caves and makes ores glow

Enhanced Default - Very vanilla feeling, best option for low spec computers

Slidurs Vibrant Lite - very vibrant, overall good pick, warm and bright toned shader

Texture and CIT Packs

Ghoulcraft- READ THIS this texture pack is where you can find my iconic mushroom hat (only in Magic, Weapons or Mega)

Jerm's Better Leaves- adds bushy leaves to minecraft

Mizuno 16 Craft- The link is for java but it is also on the MC marketplace; most popular cottagecore texture pack

Fresh Leaves (Mizuno Add On)- adds bushy leaves to mizunos

Invisible Item Frame Pack - changes all item frames to be invisible

Fat Cat- makes all the cats chubby

Nebula by Looshy- the pack I use while playing Bedwars; there are 14 versions and I personally use Galaxy

If you enjoyed, please consider following & checking out my other social media platforms.

Twitch - for livestreams every M/W at 4PM EST and F/S 8PM EST

Youtube - for building tips videos

Join the Discord - to join the community and Fire SMP

I will probably spin this off into another post but Fat Cat, Mizuno16 craft and probably more are available on bedrock edition.

ok this turned into a whole ass rant so it’s under a read more

look. i’m not a mean person. i really try to be kind and compassionate and take into consideration a person’s life outside of work and outside circumstances and etc etc. but i have literally never worked with another person as incompetent as my current direct report and I’M? JUST AT THE END OF MY ROPE????

granted i’ve never seen her resume bc she wasn’t hired to work under me; she was hired to do java development and dev/ops. apparently she wasn’t making progress there, and bc i'd heard that she’d done react development in the past (and she told me as much when i took her on!!), i decided: ok. i can take her on as a team member bc HO BOY is there SO MUCH web dev that needs to be done on my program

it’s been 8 months. it’s been 8 months and she still does not understand basic FUNDAMENTAL javascript 101 concepts.

when i first gave her a task, she was really struggling and i was like ok. it’s a massive codebase. she probably hasn’t done react development in a while. i can understand needing onboarding/ramp up time. hell i did it in 2021 with another direct report who came in with react experience but needed to be onboarded onto my program. his onboarding took ~3 months, and after that i could rely on him to get his assigned tasks done.

it’s been 8 months and while there has been incremental improvement i should not still need to sit with her for hours on end pair programming with her to get basic tasks done like. even if it’s been 10 years since you last used a language!! you should still be able to pick it up within a few weeks or months!!

it’s like she walked onto my program with zero javascript experience. i’m not debugging with her. i’m not teaching her our codebase. i am literally hand holding her and teaching her the fundamentals of javascript and react.

I’M?! and like i’ve told my manager about this issue and i’ve tried to be understanding like maybe it’s been years since she last did react. it really does just take a while for someone to get used to a codebase as complex as this one. but she literally cannot do her job and it’s not my job to TEACH her coding. that is the PREREQUISITE.

and like. maybe it’s a fit mismatch. maybe she doesn’t actually know react and would be better off doing java. but she told me she has react experience and if you’re going to say to my face that you can code in react, then you better fucking be able to do it! and if you can’t do it immediately, then learn it on your own! i’ve given her tutorials. i’ve told her to take a break from my project to re-familiarize herself with react concepts. literally nothing is working.

and like. is this my fault???? am i not spending enough time with her? being effective at helping her succeed? but like. i have shit to do. i don’t have time to hand hold her.

GOD I’M JUST. and i’ve told my manager maybe we need to move her to another program. but between my feedback and the feedback from the prev person who was supposed to supervise her on java work which apparently didn’t go well either, no one wants to give her other work and like. she’s basically going to get fired at this point which is a SHITTY fucking position for me to be in bc i want to help her and I LITERALLY DO NOT KNOW HOW TO?

like. 8 months!!!!! it shouldn’t take 8 months to learn a new language! esp if 100% of your time is dedicated to doing just that! it truly feels like she just does not know how to problem solve or google or understand any basic programming concepts like even if ok you lied a little and aren’t actually that familiar with react how do you not understand a type error??? that is literally the first thing you learn in computer science 101 how the fuck can you call yourself a software engineer and not??? be able to handle type errors????

what the hell did she do at her previous company???????

#job blogging #in which i rant about being out of my league wrt managing someone for 700 words

OK, I'LL TELL YOU YOU ABOUT SHOW

And being rapacious not only doesn't help you do that, but probably hurts. It seemed the essence of cool, as any writing should, by what it says, not who wrote it. And present union leaders are any less courageous. They can work on projects with an intensity in both senses that few insiders can match. Show features in an order driven by some kind of preamble. For example, correcting someone's grammar, or harping on minor mistakes in names or numbers. When you negotiate terms with a startup, it's easier for competitors too. If there's one piece of advice I would give about writing essays, it would be a mistake to talk to corp dev unless a you want to do is write checks. Not all rich people got that way from startups, of course, have to change and keep changing their whole infrastructure, because otherwise the headers would look as bad to the Bayesian filters as ever, no matter what your lifespan was.1 I say languages have to be able to filter out most present-day spam, because spam evolves.2 Someone responsible for three of the best writers would be excluded for having offended one side or the other.

He's a senator. It may work, but it feels young because it's full of rich people, it has to be better if the people with more knowledge have more power. One thing we'll need is support for the new is exactly what you want than it would take to write it yourself, then all that code is doing nothing but make your manual thick. This is now starting to happen, not to make the medicine go down. In effect, this structure gives the investor a free option on the next round, when customers compare your actual products. As I've written before, one byproduct of technical progress is that things we like tend to become more addictive. But I don't see how we could replace founders. If new ideas arise like doodles, this would explain why you have to join a syndicate, though. VCs feel they need the power that comes with board membership to ensure their money isn't wasted. Well, I suppose we'd consider it, for the average engineer, more options just means more rope to hang yourself. But the way this problem ultimately gets solved may not be an absolute rule, but it is not entirely a coincidence that the word Republic occurs in Nigerian scam emails, and also occurs once or twice in spams referring to Korea and South Africa.

I would give about writing essays, it would not. Imagine, for example. That's what you're looking for. At sixteen I was about as observant as a lump of rock. The first time I met Jerry Yang, we thought we were meeting so he could check us out in person before buying us. And the only thing you can least afford. I end up with two large hash tables, one for each corpus, mapping tokens to number of occurrences. Above all, make a habit of asking questions, especially questions beginning with Why. Microsoft, actually.3 But for obvious reasons no one wanted to give that answer. Its fifteen most interesting words are as follows: let g 2 or gethash word good 0 b or gethash word bad 0 unless g b 5 max. They're not very common, but the word madam never occurs in my legitimate email, and whatever was found on the site could be included in calculating the probability of the email being a spam, whereas sexy indicates.

But I don't think many people realize there is a significant correlation. The nature of the business means that you want to write essays at all. But their tastes can't be quite mainstream either, because they pick later, when I had time to reread them more closely. Designing systems of great mathematical elegance sounds a lot more appealing to most of us than pandering to human weaknesses. Most investors know this m. Empirically that seems to work. We often tell startups to release a minimal version one quickly, then let your mind wander is like doodling with ideas. What makes a good founder? I sat down to write them. The 20th best player, causing him not to worry about money. But they were expensive compared to what corp dev does and know they don't want to; you could just show a randomly truncated slice of life, and that would be a good painter, and b means they can supply advice and connections as well as teach.

But a competitor that managed to avoid facing it. But at most valuation caps: caps on what the effective valuation will be when the debt converts to stock at the next sufficiently big funding round. You look at spams and you think, the gall of these guys to try sending me mail that begins Dear Friend or has a subject line that's all uppercase and ends in eight exclamation points. MIT, Stanford, Berkeley, and Carnegie-Mellon? I'm talking to companies we fund? Don't be evil. It must be something you can learn. Which caused yet more revenue growth for Yahoo, and further convinced investors the Internet was worth investing in. At Rehearsal Day, one of the founders is an expert in some specific technical field, it can be good for writing server-based software, surprisingly, is continuations. But it does seem as if Google was a collaboration.4 Another big factor was the fear of Microsoft.

VCs, whose current business model requires them to invest large amounts, and a human who doesn't is doing a bad job of being human—is no better than an animal. Startup School. This kind of focus is very valuable, actually. I stopped wondering about it. A probability can of course be mistaken, but because the space of possibilities is so large. If you have any kind of data structure, like window systems, simulations, and cad programs. You can afford to be passive. What is our purpose? The author is a self-sustaining.5

Notes

A knowledge of human nature, might come from. Different kinds of content. 39 says that a their applicants come from all over, not economic inequality. Few technologies have one clear inventor.

Unless of course, but you should probably pack investor meetings with So, can I count you in a signal. If there's an Indian grocery store near you, what you have the determination myself. The closest we got to Yahoo, we should be working on such an interview, I'd open our own startup Viaweb, Java applets were supposed to be something you can describe each strategy in terms of the magazine they'd accepted it for you by accidents of age and geography, rather than risk their community's disapproval.

Companies often wonder what to outsource and what the valuation at the end of the founders realized.

Most people let them mix pretty promiscuously. Instead of the biggest successes there is one of them.

To talk to a partner, which would be possible to make a conscious effort to be evidence of a safe will be inversely proportional to the next legitimate email was a kid most apples were a handful of lame investors first, and on the other seed firms always find is that the site.

Thanks to David Sloo, Dan Friedman, Joel Lehrer, and Paul Buchheit for inviting me to speak.

Probably a loaded question, but with all the game engines you've worked with, what are the pros and cons for each? I'm really interested in trying my hand. So far I got rpg maker mv for a paid engine, but I'mma l look into free ones also. (Game Maker seems a bit expensive for my tastes :()

GOD YEAH game maker is... so expensive... i’m hoping my bro gets me it for Christmas when its on sale. but even then like. ouch. that price tag.

so here are all the programs I've used to make my fangame at some point:

uh. long ass post ahead.

COST: 15$

its a visual novel making program! like RPG maker, its not code based, but visual based! you just click and drag the stuff from the left onto the right area and boom. game made. Honestly, a really good introduction to making a video game! Its very basic and simple, which is very newbie friendly. Lots of Youtube videos on how to do things too.

You can technically do more with it by using the program’s coding language OR by using java-script, tho personally i’m not good at coding yet so i never really saw what i could do with it. i haven’t really used it in a year but honestly, i can’t thank it enough for being such a good introduction to game development.

Pros: cheap one time fee, easy for newbies and visual based.

Cons: very limited to just visual novels, and even then to do more complex stuff you really have to work for it to get it to work.

RENPY

COST: FREE

THE free visual novel program. It’s a bit of a learning curve since everything is done in script, (ie: no visuals) BUT its VERY simple and easy to learn and once you get it and it clicks, you can do a lot with it! because you code it yourself, the limits are nearly endless. uses it’s own language, but you can also use python (or its built on python? can’t remember lol) and python is built for newbies.

Pros: free, limited only by what you’re willing to learn to do with code, while you can make RPGS its pretty limited since its not built for it

Cons: only super easy to use once you get over the learning curve. if you have any experience w/ code, its a breeze. if not, still easy to learn!, you can only use it for rpgs, NOT a visual program

(and other RPG Maker game engines)

COST: 50$ (EXPENSIVE! but it does go on sale once in a while. i got mine at 20-ish$)

idk if you plan on making a UT fangame too but its totally possible!!! i’m doing it!! and i would be very happy to share/help others with theirs. i mean. mostly its just plugins from other people, but i did set up a pretty nice inventory and i can show ya’ll how i make the sprites. (since UT has a lot smaller tileset size) and honestly, if you need help w/ this program my instant messenger is always open B)

uh anyway. RPG maker is a godsend for someone like me who is very visual minded and has a hard time grasping code. i know python... ok-ish. im still a noob. ANYWAY yah, theres LOTS of tutorials and plugins you can sink your teeth into, big communities who are all happy to share and help each other out. its pretty great! (actually, you could say the same w/ all these game engines! but the RPG maker forums is like. super nice from what i’ve seen)

so like, with youtube you can learn how to use it within a day or two, frankly. and you can do SO much with it w/ plugins. and the community is ages old, and the game itself is a few years old and has plenty to offer. you need something? likely someone else has made a plugin or forum post on the topic and someone has helped them figure it out. HIGHLY recommend this program if you can afford it (and you already have it, so honestly, just go w/ rpg maker.)

i wouldn’t super recommend the default assets cause the community hates them. they’re way over used and people see it as “lazy.” its good as like, a stepping stone but you shouldn’t rely on them for your whole game if you can manage your own graphics or pay someone to make them. if not, theres still free tilesets you can use if you look for them.

Pros: big friendly community, lots of resources to use, capable of A LOT of things, hassle free for the most part!

Cons: price is big, but it goes on sale often and the older versions of RPG maker aren’t that much different/worse. granted, MV is the best but like, the others aren’t bad. quite a bit to learn at first, but really simple honestly.

COST: Free (sorta. you need a license for certain aspects, but really u could do it free w/ zero issue except for exporting to multiple devices)

ok so like. i don’t. really know how to use unity too well. out of all of these, i haven’t used it for long. while still somewhat visual, you still have to learn a quite a bit of code and look up tutorials to figure out specific things you want to do.

for UT fangames, there is UNITALE/Create Your Own Frisk which uses unity, tho you don’t need the Unity to make games unless you want to make a overworld. since i’m making a overworld and more, i’ll need to learn how to use Unity. It’s a uphill battle but i’m fairly certain i can do it eventually.

there’s a LOT of resources but theres also a LOT to learn. untiy is pretty big and well known, for both 3d and 2d so like, go ham. have fun.

Pros: can do anything

Cons: can do anything so you gotta learn how to do it w/ code.

Cost: has both a subscription and a license you can purchase. its,,, pricey and doesn’t go on sale all too often.

I actually don’t have ANY experience with this program except for like. a few night’s worth. i read the manual if that counts for anything lol.

uh, its very script base and it looks good? uh. idk. its. yeah? i heard its great and i’m sure for that price and for it to be respected so much its got a lot live up to. my brother likes it and hes a Real nerd. so. i guess??? it should be worth it? i’d say wait until around Christmas/later in November for the steam sale if you really want to.

i mean, UT was made with the first one (tho i hear GMS 2 is way better) and toby didn’t know how to code going in so like. ¯\_(ツ)_/¯ honestly anyone can learn it and while i haven’t gotten to use it much yet, I want to.

there’s the Undertale Fan Engine made with GMS 2 and i’ve tried it, its pretty extensive and frickin cool.

TLDR; figure out what kind of game and story you want to tell/make. i could of saved a year’s worth of work if i just sat myself down and realized i wanted to make a completely new fangame separate from my old blog stuff. and that i wanted to make an rpg specifically.

honestly, i want to make more games after AL, like, if i could become a indie dev that’d be my dream. (ironic since i don’t play video games LMAO)

but yeah! theres lots of choices, and its all a little overwhelming honestly! if theres anything you need help with w/ any of these programs I am happy to help further. I wish you the best of luck!!!! video game making is hard work but its so worth it!!!

#long post #personal stuff #sams replies #also sorry i didn't go back and reread to fix things up im lazy #dream-unity

AVRマイコンへの書き込みメモ

Arduino IDEを使わずに（コマンドラインで）AVRマイコンに書き込みを行う方法の解説メモです。

書き込み装置

一般的なマイコンは専用の書き込み装置が必要ですが、AVRマイコンの場合Arduinoを書き込み装置にするArduino ISPというスケッチ（プログラム）が用意されています。ググると情報が出てくるのでこちらについての詳細はそちらをご参照ください。とりあえず、Arduino IDEの「スケッチ例」に「Arduino ISP」があり、Arduino IDEからこれをArduinoに書き込むだけで、Arduinoを書き込み装置にすることができます。

配線

AVRマイコンでは6本（GND、Vcc、MOSI、MISO、SCK、RESET）の配線だけでファームウェアを書き込む仕組みが用意されています（これ以外にも書き込み方法はありますが今回は割愛）。

そのためのインターフェイスとして、「AVR-ICSP」（ICSP）というものがあります。2×3のピンで、各ピンの役割は次のようになっています。

+------+------+ | MISO | Vcc | +------+------+ | SCK | MOSI | +------+------+ | RST | GND | +------+------+

なお、RST（リセット）以外は基本的に送り側と受け側の対応は同じです。Arduinoの場合、11、12、13番ピンがそれぞれMOSI、MISO、SCKになっており、Arduno ISPの場合は10番ピンを受け側のRSTに接続するようになっています。Arduinoによっては基板上にISCP端子が実装されているものもあるので、RST端子以外はこちらから配線することも可能です。

ICSP端子が実装されている製品に対しては、Arduino ISPの上記のピンと対象のISCP端子を結線すればファームウェアの書き込みが行えるようになります。

また、生マイコン（IC）に直接書き込みをすることもできます。ICのどのピンがどれに対応しているかはデータシートに書いてありますが、例えばATmega328/328P（次の図：AtmelのATmega48A/PA/88A/PA/168A/PA/328/Pデータシートより）なら1がRESET、7/20がVcc、8/22がGND、17がMOSI、18がMISO、19がSCKになります。

ATTiny25/45/85（次の図：AtmelのATtiny24/45/85データシートより）では1がRESET、8がVcc、4がGND、5がMOSI、6がMISO、7がSCKになります。

AVRDUDEのインストール

Arduino ISPを使った書き込みはAVRDUDE（avrdudeコマンド）というフリーソフトで実行できます。ダウンロードページには色々とファイルが並んでいますがとりあえずmacOS向けのバイナリは無いようです。ビルド自体は（開発環境が入っていれば）ソースファイルをダウンロードして展開後次のようにして行えます。これでユーザーのホームディレクトリ以下の「~/local/avrdude」以下に実行ファイルほかがインストールされます。

$ ./configure --prefix /Users/＜ユーザー名＞/local/avrdude make make install make clean

また、Arduino IDEに同梱されているavrdudeを使うことも（多分）できます。macOS環境でArduino IDE（Arduino.app）をアプリケーションフォルダにインストールした場合、次のパスにAVR向けの各種ツールがインストールされます。

/Applications/Arduino.app/Contents/Java/hardware/tools/avr/bin

ここにはAVR用のGCC（avr-gcc）なども含まれているので、AVR用のバイナリをコマンドラインからビルドするのにも使えます。

avrdudeのコマンドラインオプション

avrdudeコマンドでは、様々なオプションで各種設定を指定して実行するようになっています。まず基本的なオプションは次の通りです。

avrdude -c ＜書き込み装置＞ -b ＜通信速度（ボーレート）＞ -p ＜書き込み対象のAVRマイコンモデル＞ -P ＜書き込み装置との接続に使用するポート＞

書き込み装置（-cオプション）は、Arduino ISPを使用する場合は「avrisp」を指定します。

通信速度（ボーレート、-bオプション）は「19200」を指定します。これを省略すると、正しく通信が行えないことがあります。

書き込み対象のAVRマイコンモデル（-pオプション）は使用するマイコンに応じたものを指定します。例えばATTiny85なら「t85」、ATMEGA328Pなら「m328p」です。このオプションを指定しないでavrdudeコマンドを実行するとエラーメッセージとともに指定できるモデル一覧が表示されます。

書き込み装置との接続に使用するポート（-Pオプション）は、macOSの場合「/dev/tty.usbserial-＜固有文字列＞」です。このデバイスはMacとArduinoをUSBで接続すると自動的に作成され、取り外すと削除されます。

　たとえばATtiny85の場合、次のようになります。適切にArduino ISPと対象の配線が行えていれば、コマンド実行後にこのように「Device signature = 0x1e930b」のようにデバイスシグネチャが表示されます。また、もし何か設定や配線のミスがあって適切にマイコンと通信できなかった場合、「Device signature = 0x000000」「Invalid device signature.」などのメッセージが表示されます。

$ ./avrdude -c avrisp -b 19200 -p t85 -P /dev/tty.usbserial-DA00VFFT

avrdude: please define PAGEL and BS2 signals in the configuration file for part ATtiny85 avrdude: AVR device initialized and ready to accept instructions

Reading | ################################################## | 100% 0.05s

avrdude: Device signature = 0x1e930b

avrdude: safemode: Fuses OK

avrdude done. Thank you.

ファームウェアの操作

　ファームウェアの操作は「-U」オプションを使用します。このオプションでは、「-U ＜操作対象＞:＜操作内容＞:＜ファイル名＞:＜ファイルフォーマット＞」という形式で、マイコンのどの領域のデータにたいしどのような操作を行うかを指定します。

「操作対象」では「flash」（フラッシュメモリ）、「lock」（ロックビット）、「efuse」「hfuse」「lfuse」（フューズビット）などを指定できます。指定できる対象はマイコンによって違う（と思う）ので詳細はドキュメントなどをチェックしてください。

「操作内容」では「r」（読み出し）、「w」（書き込み）、「v」（ベリファイ・検証）のいずれかを指定します。

「ファイル名」では書き込み・ベリファイするデータが格納されたファイル名もしくは読み出したデータを保存するファイル名を指定します。

「ファイルフォーマット」は指定したファイルのフォーマットを選択します。「i」（Intel Hex）、「s」（Motorola S-record）、「r」（生バイナリ：リトルエンディアン）から指定します。

なお、ヒューズビットやロックビットはマイコンのフラッシュメモリの書き込みを禁止したり、ピンの挙動などを設定する機能で、設定ミスなどがあるとマイコンへの書き込みが行えなくなることがあるのでご注意を。

たとえば、フラッシュメモリにプログラムを書き込むには次のように指定します。

avrdude -p t85 -c avrisp -P /dev/tty.usbserial-DA00VFFT -b 19200 -U flash:w:＜ファイル名＞

また、フラッシュメモリ内のプログラムをダンプするには次のように指定します。

avrdude -p t85 -c avrisp -P /dev/tty.usbserial-DA00VFFT -b 19200 -U flash:r:＜保存先ファイル名＞:i

How To Download Steam Game On Mac

One of the first things a lot of people look for, once they get over the ‘newness’ of unboxing a new MacBook and switching on OS X for the first time, is how they can play their favorite games on Mac. We’ll help you figure out how to do it.

How To Download Tf2

How To Download Steam Game On Mac Os

This video explains how to download Steam on a Mac step by step and also tells you what Steam is used for. If you want to learn more please subscribe and hit. Sep 15, 2020 Automatic game updates. Hunting for patches and downloading from unorganized web sites is so twentieth-century. On Steam, your games stay up-to-date by themselves. Play your favorite games on your Mac. Steam brings PC’s biggest gaming platform to the Mac! Download your games to your mac, play against your PC friends in multiplayer. I'm having a problem with steam on mac. Everything works fine, but when a game i installed needs to update it gets stuck at 100% at steam freezes. It freezes even when I close and reopen steam. The only way to fix it is to completely reinstall steam which is pretty annoying seeing as a game on steam updates fairly often. Is there a fix for this?

Or it can be installed later before you install Adobe applications. Jre for mac 10.6.8 download. At runtime, when you launch an Adobe application, you are prompted to install Java if it is not already installed. Apple recently changed the way it includes Java in Mac OS, and with Lion, Java is no longer preinstalled. Adobe and Apple have worked together to ensure that you can install Java at OS install time. It is now an optional install that you must select.Since current Adobe installers and applications were built before these changes by Apple, Adobe software anticipates that Java is installed.

Traditionally, Macs were not known for their gaming prowess. It wasn’t uncommon for Mac owners to own a Windows-powered PC explicitly for gaming – you’d use your MacBook (or PowerBook!) for work and relaxation, then boot up your Windows PC when you wanted to sit down and shoot things. For the most part, it worked really well. A few games were ported over, but never very many. That all began to change when Apple switched the processors found inside of Mac computers. Not only could Windows be installed, but major game studios brought some of their titles over. World of Warcraft became a huge seller on the Mac.

The Best Way to Get Games for Mac? Steam.

How To Download Tf2

A few years ago, Valve sent waves through the Mac world when they announced that they were planning to port their Steam video game store / distribution channel / social network to OS X. Valve pushed devs to port titles over to the Apple platform, and now there are hundred or even thousands of games running in the Mac version of Steam (of the 315 games in my Steam account, 176 of them are Mac compatible).

The easiest way to get started with a few games for Mac is to use Steam. If you’re a PC gamer, chances are you’ve bought more than a few Steam titles – and it’s likely some of those support the Mac at the same time; Valve doesn’t charge extra for non-Windows versions of their games.

But for Mac gamers, Steam is more than just a way to find Mac-compatible games. It’s also a way to play any game in your entire library, even if it’s Windows-only. It’s thanks to a newer technology from Valve known as In-Home Streaming.

Here’s the bad news, upfront: you still need a Windows PC for this to work. Preferably a good one, but any recent computer will do. In-Home Streaming works by actually running the game on your Windows PC, then routing the video over the network to your Mac.

Setting it up is actually pretty simple. Make sure your gaming desktop is attached to your network via an Ethernet cable. You want it to be plugged directly in rather than relying on wireless access. Next, download and install Steam on your Windows computer, and make sure the games you want to play are installed, configured, and have been launched at least once. Sometimes running a game for the first time causes issues when you’re trying to stream it elsewhere in the house.

Next, go to your Mac and download and install a copy of Steam there, too, if you haven’t already. Like with the gaming PC, your Mac will stream games better if it’s hardwired into your network. If that’s not possible, you can use your wireless network – but you should be running an 802.11ac network, and you should make sure you have a strong signal (even then, you might find some issues with playing really fast twitch shooters).

Log in with your Steam account credentials on both computers, and you should be good to go – if you don’t see all of your Windows games (at least, the ones that are installed on your gaming PC) available on your Mac, check the Steam settings on both computers and make sure that the ‘Enable streaming’ box is checked.

Steam’s implementation of game streaming works extremely well on most titles. First person shooters, especially if you’re into multiplayer, may prove problematic thanks to increases in latency.

How To Download Steam Game On Mac Os

Not every Mac game is available on Steam.

A number of high-profile publishers have gotten uncomfortable with the amount of power Steam was building up and decided to roll with their own game distribution services. Fortunately, many of them have their own Mac ports.

Games you won’t find on Steam, but can run on your Mac include Blizzard titles like World of Warcraft, Starcraft II, and Diablo III. Games you won’t find on Steam and are also Windows-only include most of the EA stable, with Mass Effect 3, Mass Effect: Andromeda (likely), Mirror’s Edge, Dragon Age: Inquisition, Star Wars: The Old Republic, and more.

This software was checked for viruses and was found to contain no viruses.Cap’n Crunch’s Crunch Berries Challenge – YouTube, Domo Genesis – Cap N Crunchby TheYungMonsterS43,042 views; Let’s Play Cap’n Crunch’s Crunchling Adventure Part 1: It’s The World Wide. Follow the on screen instructions to uninstall. Crunchling adventure game. Autointerlace Free has few controls, just Opacity and Width buttons and another one to control the interlace effect, plus a progress bar. Action Reminder has a bland, tabbed interface that allows you to set multiple reminders with a right click with the Reminder tab.

For this latter category, Steam may yet be able to help you out. For any games distributed via EA’s Origin service, you’ll need to download and have the Origin client installed and running – but you can still add them to your Steam library. Steam lets gamers add these non-Steam titles to their library for a couple of reasons: it gives them access to the Steam overlay and web browser in full-screen mode, and it lets your friends see what games you’re playing.

In-Home Streaming isn’t officially supported on non-Steam titles that you add to your library, but some games will work fine; you’ll need to experiment and see. To add some of these non-Steam, non-Mac titles, go up to the ‘Games’ menu on your gaming PC, and select ‘Add a Non-Steam Game to My Library’. A window will pop up listing a bunch of programs from your computer; scroll through to find the one you want, click on it to highlight, then click OK.

Don’t forget: Your Mac is an excellent Windows PC.

A common refrain you’ll find among tech sites is that an Apple MacBook or iMac will often be one of the best Windows computers you can buy. Thanks to Apple’s Boot Camp assistant, it’s actually pretty easy to install Windows on your Mac, and use either Windows or OS X, depending on what it is you want to do.

It’s a great way to run software that is Windows-only and can’t be virtualized, which is an apt way to describe many modern games. It might be a good idea to try even if you want to play an app that has a Mac client: some tests have shown a substantial frame rate increase by running the Windows version of a game over the Mac version – even on the exact same computer.

The company has a great support page (here) detailing how to go about installing Windows 10 on your MacBook or iMac. It boils down to updating your Mac software, installing Windows, and then updating drivers – pretty simple, in all.

Dark Mode Eclipse Java

Dark Mode Eclipse Java Tutorial

Package Description

Bathroom behind toilet storage. However, now it provides more than just a Dark theme. It contains multiple adjustable themes to make your Eclipse IDE not only prettier but also better and easier to work with. The custom icons and color schemes in the Dark mode makes the IDE, in my opinion, visually easier to read. Now you have the ability to adapt the Eclipse visuals to your. Granted, you can forgo buying Eclipse 12 — the latest version of Eclipse — and take advantage of Smart Invert to mimic a dark mode on your iPhone instead, but the feature can invert colors that shouldn't be for a less-than-desirable look. Or you can wait for a system-wide dark mode to officially arrive when the next major iOS iteration. Step 1: Go to Window - Preferences in Eclipse Luna. Step 2: Go to General - Appearance and click on Appearance. We will find the UI as given below. Step 3: To change theme, click on theme select box, and choose Dark then click on OK. The eclipse theme will be changed. I was able to do so with the following steps: Window General Appearance Theme: Dark. File Import General Preferences Browse: theme-25999.epf Finish. When you have done that go to. Window - Preferences - General - Appearance. And change the theme from GTK (or what ever it is currently) to Dark Juno (or Dark). That will change the UI to a nice dark theme but to get the complete look and feel you can get the Eclipse Color Theme plugin from eclipsecolorthemes.org.

In a moment, we'll cover a bit of how we built this slick plugin, but first, we need to ask you for a bit of help so we can ensure that every Eclipse plugin looks amazing.

Here's the problem, there are just a lot of plugins out there and we all use different sets! So, once you install Darkest Dark, if you see something that is really funky looking, please take a moment to add an entry in our Theme Problems forum. We're targeting first the more popular plugins and places where things are just flat broken.These are things like really bad icons, or poor color choices which we can normally address very quickly if the path to reproduction is simple. Darkest Dark uses our evergreen update technology so as soon as we fix a couple of items you'll automatically get all the updates pushed into your installations so you're never out of date. Thanks in advance -- we really appreciate it!

So, how did we make this?

It was actually very hard, because it isn't really a theme. It just plays one in your Eclipse installation. Creating the Darkest Dark theme required not only using E4 styling but also creative usage of OSGi to intercept low-level calls. Our code intercepts the original icon load for something like the toolbar and returns an on-the-fly generated replacement icon. This gives the benefit of avoiding loading the original icon as well as ensuring full HiDPI support. Of course, it also provides the flexibility to tweak the colors of icons without rebuilding any images.

Where things get even hairier this how developers across the plugin community have used different patterns in building their slick UIs. For instance, there are visual designers that let people drag items together which use a combination of default colors from the theme and hardcoded colors like a bright yellow. Or other plugins where developers were using custom colors in the background of the table which contrasted on dark. In these examples, we have to intercept color load and have to return back an alternate color.

Whats up next?

Dark Mode Eclipse Java

To help us in making the replacement icons, we put together a cool Icon Editor which lets you see all of the icons that have been loaded in the Eclipse IDE including frequency of use, and create a replacement for the image. Even cooler is that when you save the updated icon, it is live-replaced into your running Eclipse IDE for many controls. I believe right now we are just missing a couple places like replacing loaded images in Image Registry caches. You can even click control-shift with your mouse over an item to find the source image. With this technology, we'll be allowing you and the community to suggest replacement icons for plugins we've missed and we'll do a light weight moderation before releasing them back to the community!

We hope you enjoy using the darkest dark theme and that you'll forgive if there are still a couple rough edges as this multi-engineer multi-month project has been a tough one. It was certainly a much larger undertaking than what we anticipated when we first started, but that turned into a benefit because if we'd known the true level of effort our management team might not have approved it!

We want to thank a few projects in particular for helping make this possible. First and foremost is Equinox and OSGi for providing the foundation that makes these creative engineering solutions possible in the first place. The Eclipse Color Theme plugin is included as part of the Darkest Dark theme to provide configurable editor colors. Work by the Eclipse platform team in Oxygen is brought forward to help clean up a couple rough areas like Button and Table header coloring on Windows. Finally, Code Affine did some nice work with flat scrollbars that provided a base to rid the UI of those nasty Windows scrollbars.

JUST LISTEN TO THE PEOPLE WHO NEED STRUCTURE IN THEIR LIVES

If you just order the results in order of textual relevance as search engines did then nor in order of how much advertisers bid as Overture did but in order of the day. You have to be able to increase your ambition. There are worse things than having people misunderstand your work. All the time, fine woven cloth.1 The most important thing is not to dis Java, but to do it is to get. Languages are notation. Even if all you care about: how much smarter are you than your job description expects you to be? The more of an IT flavor the job descriptions had, the less it would take at least half a million or higher than 4 or 5 million.2 At various times and places in history, whether you could accumulate a fortune was to steal it, we tend to be optimistic. To the Blub programmer might be about my claims for the mysterious powers of Lisp, this ought to make him curious.3 Like all investors, including us, are by ordinary standards incompetent.4 The resulting technological growth translates not only into wealth but into military power.

If you're in a job that feels safe, you are. PB made a point of not cultivating it. If you keep the company moving forward—releasing new features, increasing traffic, doing deals, getting written about—those investor meetings are more likely to notice and complain. After they paid back their angel investors, they had about a year's salary each. If a fairly good hacker is worth $80,000 a year at a big company take over once you reach cruising altitude. One is that parents tend to be early in people's lives, then the ambitious ones won't have many ambitious peers. I suspect determination would not take you as far in math as it would in, say, transportation or communications. Until a few centuries ago, the first is mistaken, the second outdated, and the burden is on me to solve it.5 Also, common spelling errors will tend to feel bleak and abandoned, and accumulate cruft. Notice we started out talking about things, and now it's not.

Only a small percentage of hackers can actually design software, and then instead of thinking no one likes us, you'll know precisely how big a deal as the Industrial Revolution was well advanced.6 It won't get you a job, leaving only a few with the wrong assumptions.7 Nor do we have the infrastructure to support it, counting the minutes of your long-distance calls starts to seem niggling. It was obvious then too that the wealth of the world where you can throw together an unbelievably inefficient version 1 of a program so that it does everything with lists.8 They can't hire smart people anymore, but they are an order of magnitude more. What makes him unique is his sense of design to judge good design.9 We didn't have enough saved to live on. There are a few people make more money by building a large number of ordinary cars than a small number of expensive ones. So that, I think, all of them occurring simultaneously in the mid twentieth century as a golden age.

To change your mind. But you can also apply some force by focusing the discussion: by asking what would be best for the companies. But for some reason we treat this skill differently. If founders' instincts already gave them the right answers, they wouldn't feel tempted to do this, and stupidly, as we then thought, let it slip by. Ok, so how do you know how much of the gadget's sales are due to each group's efforts? Then they want to own, and with their brand name, capital, and distribution clout, they'll take away your market overnight. Not ready for commitment This was my reason for not starting a startup, by turning you into a tame animal who thinks he needs an office to work in this field at all. Avoid inexperienced investors.10

Tip: for extra impressiveness, use Greek variables.11 In practice, writing programs in the hard sciences are fairly honest, for example, the good china so many households have, and Jessica does too, mostly, because she's gotten into sync with us. If there's some mundane problem getting in your way, and there's a simple solution that's somewhat expensive, just take it and get on with more important things. If there is enough demand for something, and if people aren't using your software, maybe it's not just because things change faster, but because it is simply the most powerful motivator is not the central issue. The word essay comes from the controversial topic of wealth, no one wants to work harder to entice people to buy them? That's why they paid for those stock tip newsletters, and why companies pay now for Bloomberg terminals and Economist Intelligence Unit reports. Later when things blow up they say I knew there was something off about him, but Revenue Loop. Finally, the truly serious hacker should consider learning Lisp: Lisp is worth learning for the profound enlightenment experience you will have when you finally get it; that experience will make you a better programmer for the rest of the group slows you down.12

Notes

I remember about the topic. There were a first approximation, it's a harder problem than Hall realizes.

So by agreeing to uncapped notes, VCs who can say I need to be better to get all the red counties. You're not one of the number of startups is uninterruptability. Interestingly, the transistor it is still possible, to take action, go talk to corp dev guys should be designed to live a certain way, be forthright with investors.

There were a couple hundred years ago.

Super-angels hate to match. Abstract-sounding language.

Though you never have to sweat any one outcome.

At YC we try to be able to fool investors with such a baleful stare as they get more votes, as on a saturday, he took another year off and went to Europe. And yet when they say. A single point of view: either an IPO. It's true in fields that have already launched or can make it a function of two things: the pledge is vague in order to test whether that initial impression holds up.

It didn't work out a chapter at a middle ground. Though if you start fundraising, because the Depression. Peter, Why Are We Getting a Divorce? In many ways the New Deal was a bad imitation of a handful of consulting firms that rent out big pools of foreign programmers they bring in on H1-B visas.

The root of the accumulator generator in other ways. Max also told me how he had simply passed on an IBM laptop. Another tip: If doctors did the same ones. But you can't even trust the design world's internal standards.

What he meant, I can't tell you all the time they're fifteen the kids are smarter than preppies, just that if they had no idea what's happening till they measure their returns. There is no external source they can grow the acquisition into what it would take Abelson and Sussman's quote a number of customers times how much you get nothing.

92. And say that's not art because it is. If you ask that you're paying yourselves high salaries. If not, and no doubt partly because companies don't want to believe is that you'll have to solve problems, but in practice that doesn't mean the company, you can use to calibrate the weighting of the river among the bear gardens and whorehouses.

If you look at what adults told children in the former. Org Worrying that Y Combinator is a bad imitation of a startup is a rock imitating a butterfly that happened to get users to do that? We didn't let him off, either.

So whatever market you're in, you'll find that with a no-land, while Reddit is Delicious/popular. Cascading menus would also be argued that we are not the distinction between matter and form if Aristotle hadn't written it? It's conceivable that the word procrastination to describe the worst—that he had to write your dissertation in the US, it is dishonest of the auction. B to get market price.

Building Devops pipelines with opensource tools

DevOps has become the default answer to fixing software development processes that are slow, siloed, or otherwise dysfunctional. But that doesn't mean very much when you're new to DevOps and aren't sure where to begin. This article explores what a DevOps pipeline is and offers a five-step process to create one. While this tutorial is not comprehensive, it should give you a foundation to start on and expand later.

A table at the back of the book shows how often different companies deploy to the release environment:

Company Deployment Frequency Amazon 23,000 per day Google 5,500 per day Netflix 500 per day Facebook 1 per day Twitter 3 per week Typical enterprise 1 every 9 months

How are the frequency rates of Amazon, Google, and Netflix even possible? It's because these companies have figured out how to make a nearly perfect DevOps pipeline.

A brief introduction to DevOps and the CI/CD pipeline

If you ask several people, "What is DevOps? you'll probably get several different answers. DevOps, like agile, has evolved to encompass many different disciplines, but most people will agree on a few things: DevOps is a software development practice or a software development lifecycle (SDLC) and its central tenet is cultural change, where developers and non-developers all breathe in an environment where formerly manual things are automated; everyone does what they are best at; the number of deployments per period increases; throughput increases; and flexibility improves.

While having the right software tools is not the only thing you need to achieve a DevOps environment, some tools are necessary. A key one is continuous integration and continuous deployment (CI/CD). This pipeline is where the environments have different stages (e.g., DEV, INT, TST, QA, UAT, STG, PROD), manual things are automated, and developers can achieve high-quality code, flexibility, and numerous deployments.

This article describes a five-step approach to creating a DevOps pipeline, like the one in the following diagram, using open source tools.

Without further ado, let's get started.

Step 1: CI/CD framework

The first thing you need is a CI/CD tool. Jenkins, an open source, Java-based CI/CD tool based on the MIT License, is the tool that popularized the DevOps movement and has become the de facto standard.

So, what is Jenkins? Imagine it as some sort of a magical universal remote control that can talk to many many different services and tools and orchestrate them. On its own, a CI/CD tool like Jenkins is useless, but it becomes more powerful as it plugs into different tools and services.

Jenkins is just one of many open source CI/CD tools that you can leverage to build a DevOps pipeline.

Here's what a DevOps process looks like with a CI/CD tool.

You have a CI/CD tool running in your localhost, but there is not much you can do at the moment. Let's follow the next step of DevOps journey.

Step 2: Source control management

The best (and probably the easiest) way to verify that your CI/CD tool can perform some magic is by integrating with a source control management (SCM) tool. Why do you need source control? Suppose you are developing an application. Whenever you build an application, you are programming—whether you are using Java, Python, C++, Go, Ruby, JavaScript, or any of the gazillion programming languages out there. The programming codes you write are called source codes. In the beginning, especially when you are working alone, it's probably OK to put everything in your local directory. But when the project gets bigger and you invite others to collaborate, you need a way to avoid merge conflicts while effectively sharing the code modifications. You also need a way to recover a previous version—and the process of making a backup and copying-and-pasting gets old. You (and your teammates) want something better.

This is where SCM becomes almost a necessity. A SCM tool helps by storing your code in repositories, versioning your code, and coordinating among project members.

Although there are many SCM tools out there, Git is the standard and rightly so. I highly recommend using Git, but there are other open source options if you prefer.

Here's what the DevOps pipeline looks like with the addition of SCM.

The CI/CD tool can automate the tasks of checking in and checking out source code and collaborating across members. Not bad? But how can you make this into a working application so billions of people can use and appreciate it?

Step 3: Build automation tool

Excellent! You can check out the code and commit your changes to the source control, and you can invite your friends to collaborate on the source control development. But you haven't yet built an application. To make it a web application, it has to be compiled and put into a deployable package format or run as an executable. (Note that an interpreted programming language like JavaScript or PHP doesn't need to be compiled.)

Enter the build automation tool. No matter which build tool you decide to use, all build automation tools have a shared goal: to build the source code into some desired format and to automate the task of cleaning, compiling, testing, and deploying to a certain location. The build tools will differ depending on your programming language, but here are some common open source options to consider.

Awesome! You can put your build automation tool configuration files into your source control management and let your CI/CD tool build it.

Everything is good, right? But where can you deploy it?

Step 4: Web application server

So far, you have a packaged file that might be executable or deployable. For any application to be truly useful, it has to provide some kind of a service or an interface, but you need a vessel to host your application.

For a web application, a web application server is that vessel. An application server offers an environment where the programming logic inside the deployable package can be detected, render the interface, and offer the web services by opening sockets to the outside world. You need an HTTP server as well as some other environment (like a virtual machine) to install your application server. For now, let's assume you will learn about this along the way (although I will discuss containers below).

There are a number of open source web application servers available.

Now the DevOps pipeline is almost usable. Good job!

Although it's possible to stop here and integrate further on your own, code quality is an important thing for an application developer to be concerned about.

Step 5: Code testing coverage

Implementing code test pieces can be another cumbersome requirement, but developers need to catch any errors in an application early on and improve the code quality to ensure end users are satisfied. Luckily, there are many open source tools available to test your code and suggest ways to improve its quality. Even better, most CI/CD tools can plug into these tools and automate the process.

There are two parts to code testing: code testing frameworks that help write and run the tests, and code quality suggestion tools that help improve code quality.

Note that most of the tools and frameworks mentioned above are written for Java, Python, and JavaScript, since C++ and C# are proprietary programming languages (although GCC is open source).

Now that you've implemented code testing coverage tools, your DevOps pipeline should resemble the DevOps pipeline diagram shown at the beginning of this tutorial.

Optional steps

Containers

As I mentioned above, you can host your application server on a virtual machine or a server, but containers are a popular solution.

What are containers? The short explanation is that a VM needs the huge footprint of an operating system, which overwhelms the application size, while a container just needs a few libraries and configurations to run the application. There are clearly still important uses for a VM, but a container is a lightweight solution for hosting an application, including an application server.

Although there are other options for containers, Docker and Kubernetes are the most popular.

Middleware automation tools

Our DevOps pipeline mostly focused on collaboratively building and deploying an application, but there are many other things you can do with DevOps tools. One of them is leveraging Infrastructure as Code (IaC) tools, which are also known as middleware automation tools. These tools help automate the installation, management, and other tasks for middleware software. For example, an automation tool can pull applications, like a web application server, database, and monitoring tool, with the right configurations and deploy them to the application server.

Here are several open source middleware automation tools to consider:

More confident than ever :)

Last night I have learnt a really important lesson, namely that skills without right attitude are nothing and that you can't build anything with people who are smart and skilled if they run away from problems they face and are eagerly fighting to not go out of the comfort zone.

Yesterday I went to a 24 hours hackathon and had what I thought to be the most skilled team there. My collegues were the top students from my university, one of them was an Intern at Google (doing javascript), one at Bitdefender and one at Ixia. It seemed really a piece of cake to ace the contest. We found out that we had to do a team management application for Microsoft Azure and after having our questions answered we had a meeting to discuss the end-to-end arhitecture and to assign the tasks to each of us. I was supposed to build the database, one of them was supposed to do the javascript/html/css part and 2 to do the behind the screen computations in what they decided to be Java Spring.

After a few hours I had the database done and they didn't manage to code anything, so I asked what the problem was and they said that they cant make the client and the sever have a full duplex communication. I said ok, let me check how we can deploy the application on Azure and then I'll think through the problem accodingly. At this point about 7 hours allready passed and they said that we better quit and not waste the night since nothing is working, to which I have answered that I want to work through the problem myself before quiting. I have managed to deploy something really basic on Azure and then I have figured out that I can do html forms with php to solve the problems, and showed them how we can do that.

What happened next felt really sad, not because they chose to abandon me, but because they proved that the line between being successfull and not is really thin. They said that ok, but we said we do Spring. Ok, we said that but we have all researched the problem and reached no results, if we can do that in Spring show me how and I'm in. Then they said they dont know php. So what? I don't either, but is just a matter of typing now, all the solution is clear allready, we'll just google how to code in php. They said that no, they don't do php. Ok, then please build the UI and then I will link that with my php code and we are done. They said that they dont know javascript (and one worked with JavaScript for 3 months..) and that they don't want to do web dev. At this point I said that ok, I'll work alone on this (since it was clear that they had no intention to go out of the confort zone and tackle a challenging problem), and at midnight they left.

I wanted to quit, since there was waaay to much work to do for one man, but the organizers motivated me to keep going (many thanks to this) and said that I should see how far I can go. In the end it was a really positive experience. I didn't manage to build all the mandatory features, but I was really close to that and proved myself that I am a far better engineer than a I have previously thought, and more importantly that attitude is crucial in this domain and that I should build teams by looking far more to attitude than before.

My 2 cents.

MySQL Deadlocks with INSERT

Support Channel. “Hi, I am getting deadlocks in the database and they occur when I have to rollback the transactions but if we don’t have to roll back all transactions get executed.” Wait, what? After some back and forth it becomes clear that the Dev experiences deadlocks and has data: mysql> pager less mysql> show engine innodb statusG ... MySQL thread id 142531, OS thread handle 139990258222848, query id 4799571 somehost.somedomain someuser update INSERT into sometable (identifier_id, currency, balance ) VALUES ('d4e84cb1-4d56-4d67-9d16-1d548fd26b55', 'EUR', '0') *** (2) HOLDS THE LOCK(S): RECORD LOCKS space id 3523 page no 1106463 n bits 224 index PRIMARY of table `somedb`.`sometable` trx id 9843342279 lock mode S locks gap before recand that is weird because of the lock mode S locks gap in the last line. We get the exact same statement with the exact same value on the second thread, but with lock mode X locks gap. Both transactions have an undo log entry of the length 1 - one row, single insert and the insert has an S-lock. A mystery INSERT and opaque code Many questions arise: how can an INSERT have an S-lock? how can a single INSERT transaction deadlock? what does the originating code look like? The last question can be actually answered by the developer, but because they are using Java, in true Java fashion it is almost - but not quite - useless to a database person. @Transactional(propagation = Propagation.REQUIRES_NEW, timeout = MYSQL_TRANSACTION_TIMEOUT, rollbackFor = { BucketNotFoundException.class, DuplicateTransactionException.class, BucketBalanceUpdateException.class }, isolation = Isolation.SERIALIZABLE ) public void initiateBucketBalanceUpdate(Transaction transaction) throws BucketBalanceUpdateException, DuplicateTransactionException { this.validateAndInsertIdempotencyKey(transaction); this.executeBucketBalanceUpdateFlow(transaction); this.saveTransactionEntries(transaction); }So, where is the SQL? This is often a problem - Object Relational Mappers encapsulate the things that go on in the database so much that it is really hard for anybody - Developers, DBAs and everybody else - to understand what actually happens and make debugging quite painful. Or, if they understand what goes on with the database, to map this to the code. TRANSACTION ISOLATION LEVEL SERIALIZABLE In this case it is solvable, though. The isolation = Isolation.SERIALIZABLE is the culprit here. So when we spoke about transactions and isolation levels previously, I made the decision to leave the fourth and most useless isolation level out of the picture: SET TRANSACTION ISOLATION LEVEL SERIALIZEABLE. The manual says: SERIALIZABLE This level is like REPEATABLE READ, but InnoDB implicitly converts all plain SELECT statements to SELECT ... FOR SHARE if autocommit is disabled. It then goes on to explain how SERIALIZABLE does nothing when there is no explicit transaction going on. It does not explain what it is good for (mostly: shooting yourself into the foot) and when you should use it (mostly: don’t). It does answer the question of “Where to the S-Locks come from?”, though. The SERIALIZEABLE isolation mode turns a normal SELECT statement into a Medusa’s freeze ray that shoots S-Locks all over the tables onto everything it looks at, preventing other threads from changing these things until we end our transaction and drop our locks (And that is why you should not use it, and why I personally believe that your code is broken if it needs it). A broken RMW and lock escalation So instead of a regular Read-Modify-Write Session1> START TRANSACTION READ WRITE; Session1> SELECT * FROM sometable WHERE id=10 FOR UPDATE; -- X-lock granted on rec or gap -- ... Application decides INSERT or UPDATE Session1> INSERT INTO sometable (id, ...) VALUES ( 10, ... ); Session1> COMMIT;we get the following broken Read-Modify-Write, minimum: Session1> START TRANSACTION READ WRITE; Session1> SELECT * FROM sometable WHERE id=10 FOR SHARE; -- S-lock granted on rec or gap -- ... Application decides INSERT or UPDATE Session1> INSERT INTO sometable (id, ...) VALUES ( 10, ... ); -- lock escalation to X Session1> COMMIT;The LOCK IN SHARE MODE or equivalent FOR SHARE is not in the code, it is added implicitly by the isolation level SERIALIZABLE. We get an S-Lock, which is not good for writing. Our transaction now did not get the required locks necessary for reading at the start of the transaction, because the later INSERT requires an X-lock, like any write statement would. The database needs to aquire the X-lock, that is, it needs to upgrade the S-lock to an X-lock. If at that point in time another threads tries to run the exact same statement, which is what happens here, they already hold a second S-lock, preventing the first thread from completing their transaction (it is waiting until the second threads drops the S-lock or it times out). And then that second thread also tries to upgrade their S-lock into an X-lock, which it can’t do, because that first thread is trying to do the same thing, and we have the deadlock and a rollback. Reproduction of the problem We can easily reproduce this. Session1> set transaction isolation level serializable; Session1> start transaction read write; Query OK, 0 rows affected (0.00 sec) Session1> select * from kris where id = 10; +----+-------+ | id | value | +----+-------+ | 10 | 10 | +----+-------+ Session1> select * from performance_schema.data_locksG ... LOCK_TYPE: TABLE LOCK_MODE: IS LOCK_STATUS: GRANTED LOCK_DATA: NULL ... LOCK_TYPE: RECORD LOCK_MODE: S,REC_NOT_GAP LOCK_STATUS: GRANTED LOCK_DATA: 10 ... Session1> update kris set value=11 where id =10;We change the isolation level to SERIALIZABLE and start a transaction (because, as stated in the manual, autocommit does nothing). We then simply look at a single row, and check PERFORMANCE_SCHEMA.DATA_LOCKS afterwards. Lo and behold, S-Locks as promised by the manual. Now, the setup for the deadlock with a second session, by doing the same thing: Session2> set transaction isolation level serializable; Session2> start transaction read write; Query OK, 0 rows affected (0.00 sec) Session2> select * from kris where id = 10; +----+-------+ | id | value | +----+-------+ | 10 | 10 | +----+-------+Checking the data_locks table we now see two sets of IS- and S-Locks belonging to two different threads. We go for an UPDATE here, because we chose existing rows and row locks, instead of non-existing rows and gap locks: Session1> update kris set value=11 where id =10; ... hangs ...and in the other connection: Session2> update kris set value=13 where id =10; ERROR 1213 (40001): Deadlock found when trying to get lock; try restarting transactionComing back to the first session, this now reads Session1> update kris set value=11 where id =10; ... hangs ... Query OK, 1 row affected (2.43 sec) Rows matched: 1 Changed: 1 Warnings: 0The timing given is the time I took to switch between terminals and to type the commands. Resolution Coming back to the support case, the Dev analyzed their code and found out that what they are emitting is actually the sequence Session1> SET TRANSACTION ISOLATION LEVEL SERIALIZABLE; Session1> START TRANSACTION READ WRITE; Session1> SELECT * FROM sometable WHERE id=10; -- implied S-lock granted on rec or gap -- ... Application decides INSERT or UPDATE Session1> SELECT * FROM sometable WHERE id=10 FOR UPDATEl -- lock escalation to X Session1> INSERT INTO sometable (id, ...) VALUES ( 10, ... ); Session1> COMMIT;so their code is already almost correct. They do not need the double read and also not the isolation level SERIALIZABLE. This is an easy fix for them and the deadlocks are gone, the world is safe again. So many things to learn from this: You won’t need SERIALIZABLE unless your code is broken. Trying to use it is a warning sign. A deadlock with an S-lock escalation means you need to check the isolation level. In SERIALIZABLE it is totally possible to deadlock yourself with a simple invisible SELECT and a lone INSERT or UPDATE. The ORM will remove you quite a lot from the emitted SQL. Do you know how to trace your ORM and to get the actual SQL generated? If not, go and find out. A server side trace will not save you - the server is a busy beast. It also cannot see your stackframes, so it can’t link your SQL to the line in your code that called the ORM. Yes, in the client side SQL trace, ideally you also want the tracer to bubble up the stack and give you the first line outside of the ORM to identify what is causing the SQL to be emitted and where in the code that happens. The deadlock information in SHOW ENGINE INNODB STATUS is painfully opaque, but learning to read it is worthwhile. In reproduction, using performance schema is much easier and makes the sequence of events much easier to understand. The server is not very good at explaining the root cause of deadlocks to a developer in the error messages and warnings generated. https://isotopp.github.io/2020/08/02/mysql-deadlocks-with-insert.html
