what several weeks of obsessing over rapist ex-convict dick does to a mfer @threads-strings

[threads-strings]

What was one event that changed your PC? Not just their appearance but their perspective on the world, or the way the town works?

With Donn, I think his perspective changed a lot when the Scarred Prisoner attacked him and almost gouged his eye out. Not in a really traumatic way, not like being assaulted or killing someone else was traumatic to him, but more so, I think for the first time he became self aware that he‘s too trusting.

Atp he didn‘t realize just how blindly he trusted the Scarred Prisoner until he got mad that Donn didn’t pull away/run away sooner which basically made Donn go „Yeah actually, why didn’t I?“

It didn’t change him really to anything worse or better, I think it was just a very sobering thought of „oh, I really trusted this guy”, basically a “oh i really want this to be love dont I”. A sobering thought of realizing he is a dependent person, he isn’t some gruff “lone wolf” type like people think he is or he even wants to be sometimes, he wants to and does trust people very easily.

He’s sometimes like a child unironically with how low self awareness he has, like when his mother first hit him he never thought that’s a thing that even could happen because it’s always only been his father. So when she first hit him it was sort of a sobering oh. I guess she’s doing that now too.

Same goes with the Scarred prisoner, he didn’t think he’d seriously hurt him until he did. Kinda that’s how Donn goes through life a lot of times, he thinks people won’t do things to him he wouldn’t do to them until they do and he goes oh. Guess that’s something I gotta expect now, too.

It goes for both positive and bad things btw - Donn never explicitly told anyone he trusts them (action over words) and he never heard those words from anyone towards him. So when Brianna told him she trusts him it was like, oh. That can happen??? And he doesn’t know how to feel about that either.

———-

Now Faust - Obviously, his wife dying. The night the ritual happened that unleashed the eldritch horrors into town, he became aware of the corrupted nature of the town itself, and lost his faith. I hc during the ritual night, the monks/nuns protecting the temple for Virgo were sacrificed while trying to stop Auriga from entering reality, and in the process they’ve all been killed. Faust was kinda like Jordan as in he was a pure angel who didn’t know wtf was going on, and his wife was a nun. They had a holy bond and were both the shields for the temple in their innocence and pure love for each other, so the night the ritual had to be stopped/the temple was attacked, they didn’t understand what was happening.

His wife and him were targeted for being the shield of purity, and she ended up as one of the sacrifices thrown into the dimensional rift (like at Remy’s party Avery takes you to).

Faust jumped after her to try and save her, but was pulled back by his temple brothers. Not before he caught a glimpse of whatever entity entered town through the portal though before it closed forever and took his wife with it.

Faust 1000% blames the temple for what happened, for stopping him from saving his wife (delusional), and for leaving him and his wife in the dark for their own gains. Basically on the same night, during one moment where Faust could rip himself free from his capturers he took one of the ritualistic daggers and send an open prayer to whichever entity would listen to take his soul in exchange for revenge on the temple before killing himself.

And whatever came out of the portal heard him.

how to make cool blobby turing patterns in photoshop

i'll preface with i learned the basic loop from skimming a tutorial on youtube, but as someone who prefers written tutorials i'm sure many would appreciate one! also, the second part of this is some of the visual effects i figured out on my own using blending modes and stuff.

i'm using photoshop CS4 on a mac so some buttons and stuff might be in different places on windows and newer photoshop versions but all the actions are the same. my canvas is 1000x1000 pixels.

UPDATES (i'm hoping these'll show up whenever you open the readmore?)

it's possible to do something similar in krita using this plugin, made by the love @arcaedex

it's also possible to do this in photopea, a free browser alternative to photoshop! the results are pretty much identical.

FIRST off you wanna get or make a black and white image of some kind. it has to be one layer. can be noise, a photo, a bunch of lines, whatever. here's mine, just some quick airbrush lines:

now find the actions tab. idk what it looks like in newer versions of photoshop but you probably won't need to dig!

hit the little page thingy to make a new pattern. once you hit 'record', it'll record everything you do. the little square 'stop' icon will end it.

now you want to do a high pass filter. you can mess around with the radius to change the size of your squiggles, but the tutorial had it set to 6. experiment!

now add the 'threshold' adjustment layer. i use the adjustments tab but i think there's also a dropdown menu somewhere. keep it at the default, 128. merge it down. (control or command + E or you can right click it like some kind of weirdo)

and finally, the gaussian blur! the radius of this affects the shape and size of your squiggles as well. i like to keep it around 4.5 but you can mess around with that too.

after that, hit 'stop' on the action you're recording, and then repeat it a bunch of times using the 'play' button, until you have something you like, like this:

WOW!! that was fun!! and only a little tedious thanks to the power of macros. anyway, here's some fun layer blending stuff i like to do. it's with a different pattern cause i made this bit first.

anyway, using a black and white gradient (or a grey base that you do black and white airbrush on), make a layer with the vivid light. this will make the blobs look thicker or thinner.

then, for cool colors, do a gradient map adjustment layer over that:

and finally, my best friend, the overlay layer. just using a gradient here bc i'm lazy, but feel free to experiment with brushes, colors, and blending modes!

NOW GO. MAKE COOL SHIT WITH THE POWER OF MATH. AND SEND IT TO ME

also these are not hard and fast rules PLEASE mess around with them to see what kind of weird shit you can make. here's a gif. as you can see i added some random airblush blobs in the middle of it, for fun.

[catboybiologist]

So I'm realizing that I basically have one outfit that I just make minor alterations/swaps with. I wanna keep tabs on where I got this stuff, and since I'm an attention whore, I might as well make a post out of it. With a few exceptions, everything has been stuff I've nabbed when it's on sale online or I see in a thrift store within the past couple of months.

Here's a dump of pics, some new, some old, to give you an idea of what I wear basically every day:

I really like this fit. It's professional without being stodgy, showy on the figure without being inappropriate, casual without being sloppy. I'm def "dressing up" by grad student standards, esp compared to what I used to be like as a guy, but I'm okay with that.

Now, let's steal her look!!!

Shoes:

Note that the shoes are absolutely the most expensive part of my outfit, but I have 0 regrets. I do NOT fuck around with shoes. I'm a hiker with messed up feet, I need to keep those babies working. And so far, these have been amazingly supportive on my messed up arches and ankles, I've used them in hikes even, and they support my ankle well. They also look really nice, far cuntier than hiking boots, so y'know. That's nice too.

There are two additional things I'll mention here that I know aren't easily accessible. I have pride colored hiking socks that I wear a lot which were given to me by the trailQTs. My belt was also something I got years ago from a leather worker at an art show.

Anyways. Idk if my assessment of this actually holds up, but I figured I'd record this all somewhere.

BRB... just upgrading Python

CW: nerdy, technical details.

Originally, MLTSHP (well, MLKSHK back then) was developed for Python 2. That was fine for 2010, but 15 years later, and Python 2 is now pretty ancient and unsupported. January 1st, 2020 was the official sunset for Python 2, and 5 years later, we’re still running things with it. It’s served us well, but we have to transition to Python 3.

Well, I bit the bullet and started working on that in earnest in 2023. The end of that work resulted in a working version of MLTSHP on Python 3. So, just ship it, right? Well, the upgrade process basically required upgrading all Python dependencies as well. And some (flyingcow, torndb, in particular) were never really official, public packages, so those had to be adopted into MLTSHP and upgraded as well. With all those changes, it required some special handling. Namely, setting up an additional web server that could be tested against the production database (unit tests can only go so far).

Here’s what that change comprised: 148 files changed, 1923 insertions, 1725 deletions. Most of those changes were part of the first commit for this branch, made on July 9, 2023 (118 files changed).

But by the end of that July, I took a break from this task - I could tell it wasn’t something I could tackle in my spare time at that time.

Time passes…

Fast forward to late 2024, and I take some time to revisit the Python 3 release work. Making a production web server for the new Python 3 instance was another big update, since I wanted the Docker container OS to be on the latest LTS edition of Ubuntu. For 2023, that was 20.04, but in 2025, it’s 24.04. I also wanted others to be able to test the server, which means the CDN layer would have to be updated to direct traffic to the test server (without affecting general traffic); I went with a client-side cookie that could target the Python 3 canary instance.

In addition to these upgrades, there were others to consider — MySQL, for one. We’ve been running MySQL 5, but version 9 is out. We settled on version 8 for now, but could also upgrade to 8.4… 8.0 is just the version you get for Ubuntu 24.04. RabbitMQ was another server component that was getting behind (3.5.7), so upgrading it to 3.12.1 (latest version for Ubuntu 24.04) seemed proper.

One more thing - our datacenter. We’ve been using Linode’s Fremont region since 2017. It’s been fine, but there are some emerging Linode features that I’ve been wanting. VPC support, for one. And object storage (basically the same as Amazon’s S3, but local, so no egress cost to-from Linode servers). Both were unavailable to Fremont, so I decided to go with their Chicago region for the upgrade.

Now we’re talking… this is now not just a “push a button” release, but a full-fleged, build everything up and tear everything down kind of release that might actually have some downtime (while trying to keep it short)!

I built a release plan document and worked through it. The key to the smooth upgrade I want was to make the cutover as seamless as possible. Picture it: once everything is set up for the new service in Chicago - new database host, new web servers and all, what do we need to do to make the switch almost instant? It’s Fastly, our CDN service.

All traffic to our service runs through Fastly. A request to the site comes in, Fastly routes it to the appropriate host, which in turns speaks to the appropriate database. So, to transition from one datacenter to the other, we need to basically change the hosts Fastly speaks to. Those hosts will already be set to talk to the new database. But that’s a key wrinkle - the new database…

The new database needs the data from the old database. And to make for a seamless transition, it needs to be up to the second in step with the old database. To do that, we have take a copy of the production data and get it up and running on the new database. Then, we need to have some process that will copy any new data to it since the last sync. This sounded a lot like replication to me, but the more I looked at doing it that way, I wasn’t confident I could set that up without bringing the production server down. That’s because any replica needs to start in a synchronized state. You can’t really achieve that with a live database. So, instead, I created my own sync process that would copy new data on a periodic basis as it came in.

Beyond this, we need a proper replication going in the new datacenter. In case the database server goes away unexpectedly, a replica of it allows for faster recovery and some peace of mind. Logical backups can be made from the replica and stored in Linode’s object storage if something really disastrous happens (like tables getting deleted by some intruder or a bad data migration).

I wanted better monitoring, too. We’ve been using Linode’s Longview service and that’s okay and free, but it doesn’t act on anything that might be going wrong. I decided to license M/Monit for this. M/Monit is so lightweight and nice, along with Monit running on each server to keep track of each service needed to operate stuff. Monit can be given instructions on how to self-heal certain things, but also provides alerts if something needs manual attention.

And finally, Linode’s Chicago region supports a proper VPC setup, which allows for all the connectivity between our servers to be totally private to their own subnet. It also means that I was able to set up an additional small Linode instance to serve as a bastion host - a server that can be used for a secure connection to reach the other servers on the private subnet. This is a lot more secure than before… we’ve never had a breach (at least, not to my knowledge), and this makes that even less likely going forward. Remote access via SSH is now unavailable without using the bastion server, so we don’t have to expose our servers to potential future ssh vulnerabilities.

So, to summarize: the MLTSHP Python 3 upgrade grew from a code release to a full stack upgrade, involving touching just about every layer of the backend of MLTSHP.

Here’s a before / after picture of some of the bigger software updates applied (apologies for using images for these tables, but Tumblr doesn’t do tables):

And a summary of infrastructure updates:

I’m pretty happy with how this has turned out. And I learned a lot. I’m a full-stack developer, so I’m familiar with a lot of devops concepts, but actually doing that role is newish to me. I got to learn how to set up a proper secure subnet for our set of hosts, making them more secure than before. I learned more about Fastly configuration, about WireGuard, about MySQL replication, and about deploying a large update to a live site with little to no downtime. A lot of that is due to meticulous release planning and careful execution. The secret for that is to think through each and every step - no matter how small. Document it, and consider the side effects of each. And with each step that could affect the public service, consider the rollback process, just in case it’s needed.

At this time, the server migration is complete and things are running smoothly. Hopefully we won’t need to do everything at once again, but we have a recipe if it comes to that.

Oh my. This whole ongoing mess really is crap hilarious.

The ruling is the latest twist in a battle between Tesla and labour groups in Sweden. Union IF Metall put mechanics on strike on Oct. 27, refusing to service Tesla's cars because the company would not accept collective bargaining.

Members of other unions, including dockworkers, electricians and cleaners have since taken action in sympathy.

Tesla has a policy of not signing collective bargaining agreements and says its employees have as good, or better, terms than those demanded by IF Metall. The union says it is vital to the Swedish labour market model that all companies have collective agreements...

Seko, the union that organised the PostNord workers, told Reuters an easy solution for Tesla was to sign the collective bargaining agreement with IF Metall.

So yeah, the agency issuing the licence plates needs to find some way of getting them to Tesla, without any obligation on anyone else to actually deliver them.

It also sounds remarkably like someone at the Transport Agency was being purposely obstructive there too, beyond normal-level dealing with bureaucracies. They also probably did NOT particularly want to piss off the postal workers in question, by trying to circumvent their existing shipping contract while said postal workers were refusing to deliver to Tesla.

A little more background:

So yeah, good luck getting anything done when basically every other industry is refusing to deal with your business, or even deliver its mail. You would think that whoever was actually making certain decisions at Tesla would have learned from the similar Toys 'R' Us debacle in the mid-'90s.

My guess is that they were at least hoping that nearly 30 more years of neoliberal influence might have weakened organized labor enough for them to get away with pulling this shit now. Either that, or 'just' contravening the Being Bloody Stupid Act of 1581. And then freaking Elon did an Elon, and responded to any criticism by doubling down on some terrible choices.

I can only hope that, if this was the line of thinking? That someone was sorely mistaken, and severely underestimated how well the whole Nordic Model has managed to hold up.

i love how the drifter immediately mentioned robot loving up at the front. they know how to get his attention

as one of the system admin in my lab when i heard anything about hosting wiki i see trouble... well maybe not that much but we added a bunch of services this semester and that's still part of the trouble

oh yeah you don't have docker and probably don't have good vm technology too... well that sounds more like a hassle now. good for you amir, good for you.

hope techrot don't hack your server or whatnot considering there's literally a bunch of fucked up infested plants inside this very building for easy physical access

i... literally forgot that. about the "life on other planets" part.

aww. also maybe i really should've played the whole main campaign again.

huh... never thought about that. basically free human floating

i mean... everything is relative i guess. we discover something in every era.

...maaaaaybe except in warframe because the orokins are just too advanced so people might be better off making do with "old" technology.

can we just get to the backroom sex part already im planning to date you this year.

that is probably one of the most fucked up shit i said in my life.

hey builderman , i need help :( how do i model a 3d cube 💔

Well, that's the great thing about our game engine, you don't have to use any third party programs!!

Open Roblox Studio and search for this little window! Basic objects!

Just search for and import a part from here! To make it a square just make it the same studs long as it's tall!

Tada!!! :D

Now it should show up in Explorer under 'Workspace.' Just select that, go to the Properties docker and edit whatever properties you want!

Good luck building creator!!

[andmaybegayer]

oh hey that makes sense. I have NTP coming in to this microcontroller over wifi and you can just... make os.date() calls from Lua to get the current time of day, because that goes through to the C calls, and the ESP-IDF implements all the standard time functions. Cool as hell. That really simplifies a lot of my life by moving yet more stuff into lua.

I was expecting this to require way more painful munging of data but it's very smooth and you can basically just write lua. I have a function that delays your pixel write until the next frame and it just works. I keep track of the number of microseconds you had "left" to draw before delays start happening so I can generate utilization stats, and because Lua gets its own entire core there's not really any noisy neighbours to cause jitter (which I noticed before I moved the wifi thread over)

Now for the hardest part: making an interactive webpage that is not piss. At the last work conference one of my coworkers was showing off her plugin for a docker webui and a bunch of kernel developers were like this is great but I will never send you a patch for this because the browser DOM confuses and terrifies me. And I agree with this sentiment.

[jae-in-a-trenchcoat]

Okay to explain wtf is going on:

Basically, Douxie, Zoe, Claire, Steve and Archie are fighting a wizard (I don’t have a design for him yet) who causes hallucinations (hence why everyone in the back is fighting air lol) but he can’t seem to hit Douxie.

He gets so frustrated he creates a beam of his magic that is so powerful that the impact puts everyone into a sleeping state (even tho if you look close enough his stick figure is standing, I think it would also happen to him as well), and they’re all now stuck in a dream that feels real.

We see douxie’s, where his younger self is present.

Basically a bunch of jargon for now. It’s also just some really rough sketches somewhat put together. Idk where this is gonna go, idk if it’s gonna connect to anything or not. I was just messing around w the storyboard docker on krita and I wanted to play around with a younger douxie.

[threads-strings]

how would donn react to someone (specifically an orphan) coming back to meet him, following him to the pub and the docks, basically trying to insert themself into his life after he bought them from bailey?

(i'm too embarrassed to just throw my pc at him through pms so i'm doing it through anon)

You don’t have to be embarrassed but if you’re more comfy with it you can do like a lil signature so I know it‘s the same anon/PC you ask for

Donn would think they‘re just highkey crazy, probably feel a little bad that this „kid“ (he just calls ppl kid that are way younger than him) is walking after him like some lost puppy, but he‘d still wreck their shit every time. Basically hey they‘re around me, free use toy. Not my fault they keep putting themselves into situations (<- 100% his fault). I think he‘d assault them a few times thinking eventually they‘ll stop coming around but when they KEEP coming he‘d be. Hey why the fuck are you still here kid. Are you daft. Do you have a death wish or something.

I imagine he‘d literally treat them like a stray, be dismissive at first and try „shoo“ them away and then at some point he‘s starting to leave some food outside (figuratively throwing them a bone) cuz he‘d get a little concerned this orphan keeps coming back to get their shit rocked. THAT‘S tho if the orphan isn’t trying to manipulate his life or work tho, or acting up otherwise (if they follow him around like Kylar and get possessive he‘d turn more cruel to get rid of them 💀).
