Bucharest Tech Week Conference - Monoliths in a Microservices World

Last week I was fortunate enough to have the opportunity to present at the Software Architecture Summit as part of the Bucharest Tech Week conference. My presentation, Monoliths in a Microservice World, was all new content that, by chance, worked well bringing together a number of points made by other speakers. The presentation aimed at the challenges of adopting Microservices and whether…

Looking Back

Today, 26 March 2025, is the tenth anniversary of the first time I put power to a Z80 microprocessor in a breadboard and watched it blink some LEDs.

Within a few weeks that Z80 would be completely surrounded by other chips and hundreds of wires to form my first functioning homebrew computer.

Another week and I was already removing a 68000 from a (presumed) dead motherboard, with grand ideas of moving up to the 16-bit era (but absolutely no understanding of what that would entail)

It would be another two years before the first time I put that 68000 in a breadboard and successfully used it to blink an LED.

By the time another year had rolled around that 68000 was living on a soldered breadboard and for the first time on one of my projects, it was running real software — EhBASIC.

Always looking to more challenging projects, while I was building with a 68000, I was already reading through the manual for the 68030 trying to understand how to build with a proper 32-bit microprocessor. Just one more year and I had that 68030 on a wire wrap board, blinking an LED.

The next year I was doing the most ridiculous thing I could think of — free-running a Pentium CPU on a wire wrap breadboard to blink an LED. Because I could.

By the end of the next year that 68030 had moved from its wire wrap board onto a proper printed circuit board — my first ever 4-layer PCB.

The next year saw the towering expansion of the 68030 build, adding new peripherals and functionality.

Another year and I had an all-new 68030 build on a Micro-ATX form-factor motherboard developed in just a couple months ahead of VCF Southwest 2023.

The next year I focused on developing software for my existing 68030 board stack, rather than building something new from scratch. I succeeded in developing a minimal multi-user kernel to run four instances of BASIC simultaneously.

All along in between working on these projects I have done component-level repairs on various computers, developed expansion cards for the Mac SE, built PCs both new and old, burned out hard, developed some smaller homebrew computers, had a lot of false starts, failed projects, and abandoned projects, and completed some massive projects in my day job.

Looking back at everything I've worked on over these past 10 years I am absolutely amazed at how far I have come and what I have been able to accomplish. Much of it I still don't understand how I managed to actually pull it off, and I'm not entirely sure I could duplicate my successes.

Here's to the next ten years

Hello

[silent-hill-2-official]

Apologies for necro-posting, but I looked through the notes and while people have given you some pros and cons, no one actually walked you through getting it up and running, and I might as well give my best shot at helping someone evacuate from windows 11, so here is the Jack Joy's Explanation and Guide to Linux. Chapter 0: The Pitch for the Penguin.

Linux is all about freedom. While Windows and MacOS are Walled Gardens that are slowly stripping away control from their users and extracting more and more from you, the person who is using a non-linux OS, Linux does not do that shit. Free and Open Source Software is the name of the game in Linux, as that is what is mostly being developed in that space by an army of volunteers passionate about keeping the PC personal. That comes with some caveats though. A lot of the software you use is proprietary, and while some of that is still available on Linux, most of it is not. Some you'll expect. Some you wouldn't think is even proprietary and will surprise you when you lose access to it. The Linux community has done it's best to provide solutions for a lot of these, and you will find that a lot of what you want to use has some alternative in linux, but some things will just be fucked. You trade convenience for control.

Chapter 0.5: When you are a King very few choices are simple

If the Pitch convinced you, then congrats, you now have one of the hardest decisions to make as a Linux User. What Distribution of Linux are we using? Distributions (or Distro's for short) are all different OS' who run on the Linux Kernel, the thing that gives your machine thought and makes it possible to run the hit video game Team Fortress 2 (2007). There are a lot of distributions of linux, all of which do weird things with it, but my personal Picks are as follows.

Linux Mint

Linux Mint is the gold standard for stupid simple linux distro. It just works*, it comes with a DE(desktop Enviroment) that is reminiscent of windows 7 so adjustment should be minimal and overall, is very uncomplicated. Is a bit bland tho. *(things still break sometimes).

Ubuntu

Ubuntu meanwhile you probably already heard of. Think of it as the MacOS of Linux. It has the most company support, it's DE called GNOME is very MacOS like in it's design language, incredibly stable, but also very poor in customization. If something says tested on linux, a lot of the time, it means tested on Ubuntu.

EndeavourOS

EndeavourOS is my linux distribution of choice. It's based off of Arch Linux, which is what powers the Steamdeck with SteamOS, and as such has a lot of nifty Arch linux niceties, like the Arch User Repository, and KDE Plasma as it's DE. It tries to combine being user friendly while letting you tinker with everything, it is on the cutting edge of linux, but that also means that stuff CAN break more often.

These are just my picks. Some other notable beginner friendly Linux Distros that might pique your interest could be Pop_Os, Manjaro, Elementary OS and probably a bunch of others that I forgot or don't even know exist until someone will complain at me for forgetting after writing this guide. Choice my friend. You have a lot of it, and so think about what you want from your PC and go with the distro that seems to be best suited for your usecase, whether it be as a game machine or to just use firefox and libreoffice.

Chapter 1: Performing OS Replacement Therapy on your PC

So, you know what Linux Distro you are gonna use, you know you are ready to do this, so how are we doing this? Pretty simple in all honesty. We only need:

A Flash drive (USB preferred, SD or micro SD card readers can get FUNKY)

Balena Etcher

The ISO of the flavor of Linux you want to use

Some knowledge of how to navigate your computers BIOS

And preferably a secondary boot device (IE, a second SSD in your PC)

Plug your USB into your PC, and with Balena Etcher flash your ISO onto it. If you got another USB to spare, it is a good idea to flash an image of Windows 7 onto it. Think of that second USB stick as a "In Case of Emergency, Break Glass" type of safety precaution. We don't wanna have to use it, but it's good to have just in case. Reboot your PC with your Linux flashed USB stick in, and get into your BIOS. There you are going to pull that USB stick up the boot loader until it goes before windows. If that is somehow not an option, you might have to fuck around with your PC as there might be some secure boot shennanigans going on. Consult DuckDuckGo about your specific Computer, someone already figured it out if there is a hiccup. If you were able to pull up your USB up the boot order, exit the BIOS and hopefully things should be happening. To confirm look at the screen and if it does something new (and potentially scary looking) instead of the normal windows boot sequence, it is probably doing good. After a while you should be spat back out into a "Live Enviroment" version of your OS. This version of the OS exists only for this boot, and is pulled from your USB stick. There should be an installer inside of that live enviroment version of your OS, after which it is mostly smooth sailing. Follow the Installer, but pay REAL GOOD ATTENTION to what it is sayin when it asks you where it wants to be installed, as it will create a partition somewhere on your PC. If you have a PC with an SSD that isn't being used by windows, I recommend giving it that as you'll just be able to give that entire drive to Linux without problem. If you don't have an extra SSD, you will have to cleave a chunk from the one drive you have from windows. You can just give it 50% of the drive if you want to be conservative and still retain the ability to go back to windows. But should you feel particularly pissed/want to make sure you have no escape back to windows without having to reinstall it via that second USB stick, then torch the damn thing. Once the Installer is done it will either ask you to reboot your PC or just do it itself. After which point if everything went right, you will complete your first boot of Linux and end up in the actual version of the OS you installed. If you made it there, congratulations, and welcome to Linux. You might want to update the first time you boot, but after that, feel free to poke around to see what you have installed. Get Acquainted with your new Desktop, use some of the artisanal software that is FOS, if you are feeling spicey, run some commands in the terminal (as long as you know what they do. please do not run sudo rm -rf / because you saw it on a funny linux meme, that will uninstall your entire OS.) I hope this Guide has been helpful ^w^.

Hey. Gonna gamble here. Can someone explain to me the pros and cons of Linux as a whole and tell me maybe -possibly- how one might go about getting something set up

Domingo do Frango

3D ultra-realistic badge design for a supermarket flyer, themed around “Domingo do Frango,” rendered in the style of Cinema 4D Octane Render. The composition is fully centralized, with all elements perfectly framed within the scene, ensuring no element is cut off by the edges. At the core, the text “Domingo do Frango” is displayed in large, bold, wood-carved letters with intricate, photorealistic grain texture, a rustic finish with fine grain and natural wear marks, and a warm brown finish with golden undertones, occupying 45% of the design’s height for prominence. The text is set against a rectangular, white ceramic cutting board with a subtle, smooth texture and softly rounded edges, evoking a modern kitchen surface, serving as a clean and grounded backdrop solely for the text. Surrounding the text and board, small thematic elements float freely in a circular arrangement: a miniature roasted chicken drumstick with golden, crispy texture, a small corn cob with vibrant kernels, a fresh basil leaf with delicate veins, and a wooden spoon with polished grain, all rendered with photorealistic detail and Octane Render’s high-fidelity lighting. These elements are positioned to dynamically complement the text and board, enhancing the poultry theme without overcrowding, fully visible within the frame. Positioned behind all elements, a 3D ultra-realistic chicken mascot, larger than the text, board, and thematic elements (occupying 50% of the overall design height), stands as a dynamic focal point, rendered in the style of Cinema 4D Octane Render. The chicken features photorealistic details, including individual feathers with micro-texture, textured skin with natural variations, and glossy, reflective eyes that capture light realistically. Its expression is energetic and charismatic, with a subtle, beak-curved smile and bright, engaging eyes, interacting with the viewer by pointing directly at the camera with one wing raised. The chicken’s head and upper body are centered behind the text, board, and thematic elements, ensuring the text and floating elements remain fully legible and unobstructed, with its entire form visible and uncropped within the scene. The color palette is warm and appetizing, featuring golden yellows, light browns, and creamy beiges, with accents of vibrant green from the basil and bright yellow from the corn. The typography is bold, sans-serif, with a modern yet rustic aesthetic, featuring subtle 3D depth and a wood-like, finely grained texture to harmonize with the carved text and ceramic board. The entire design is centrally framed, with dramatic, lifelike lighting inspired by Octane Render, casting soft, realistic shadows within the elements for enhanced depth. The badge and mascot are isolated on a pure white background, completely clean and free of shadows, textures, gradients, or any additional planes, perfect for a professional supermarket flyer.

What are the common applications of fertilizers produced by double roller press granulators?

Double roller press granulators produce fertilizer pellets widely used in agricultural sectors. Here’s an overview of their common applications:

1.Grain Crops

For wheat cultivation, NPK compound fertilizer pellets made by the double roller press granulator provide balanced nutrition. Applied before sowing, these granules release nutrients slowly, meeting the wheat’s needs at different growth stages – from nitrogen requirements during seedling phase to potassium demands at heading stage. This enhances both yield and grain quality.

In corn farming, customized high-nitrogen fertilizer pellets promote sturdy stalk growth and maintain dark green leaves. This improves photosynthetic efficiency, directly increasing kernel count per ear and individual grain weight.

2.Cash Crops

Cotton benefits from potassium-rich pellets during critical growth phases. When applied at bud stage and boll-forming stage, these granules boost boll-setting rates while improving fiber length and strength, ultimately increasing farmers’ profits.

Sugarcane-specific fertilizer pellets containing essential macro and micro-nutrients accelerate stalk elongation during rapid growth periods. This enhances sugar accumulation and increases the sugarcane’s sugar extraction rate.

3.Horticulture and Floriculture

For all kinds of flowers, the controlled-release fertilizer granules produced by the double roller press granulator are very suitable. Tailored to different species’ needs, they gradually release nutrients throughout growth cycles. For example, rose cultivation sees improved bloom vibrancy and extended flowering periods using such pellets.

In vegetable gardening (tomatoes, cucumbers, etc.), these pellets enable precise nutrient delivery. This results in higher yields and better taste quality while preventing over-fertilization issues common with traditional powder fertilizers.

This production method allows flexible formula adjustments to meet specific crop requirements across various soil types and climate conditions. From large-scale field crops to precision horticulture, these fertilizer pellets offer practical solutions for modern agricultural needs.

Đăng nhập:Sử dụng tài khoản mặc định (username: admin, password: admin). Lần đăng nhập đầu tiên, bạn sẽ được yêu cầu thay đổi mật khẩu.

Giao diện:Làm quen với giao diện quản lý, bao gồm các mục như Dashboard, Data Sources, Alerting, và Settings.

Bước 3: Thêm nguồn dữ liệu (Data Source)

Truy cập phần cấu hình:Vào menu bên trái chọn Configuration → Data Sources.

Thêm nguồn dữ liệu mới:Nhấn Add data source và chọn nguồn dữ liệu phù hợp với cách thu thập số liệu CPU của bạn, ví dụ:

Prometheus: Nếu bạn đã thiết lập Prometheus để thu thập số liệu từ các node. Nhập URL của Prometheus (ví dụ: http://localhost:9090).

InfluxDB: Nếu hệ thống của bạn gửi số liệu đến InfluxDB, nhập thông tin kết nối theo yêu cầu.

Lưu cấu hình:Nhấn Save & Test để kiểm tra kết nối.

Bước 4: Tạo dashboard giám sát CPU

Tạo dashboard mới:Từ giao diện chính, chọn Create → Dashboard và nhấn Add new panel.

Cấu hình panel:

Chọn nguồn dữ liệu vừa cấu hình.

Nhập truy vấn lấy số liệu CPU, ví dụ với Prometheus có thể dùng truy vấn như node_cpu_seconds_total hoặc một truy vấn tổng hợp phù hợp.

Tùy chỉnh kiểu hiển thị (biểu đồ đường, thanh, gauge, …) và khoảng thời gian hiển thị.

Lưu dashboard:Đặt tên và lưu lại dashboard để tiện theo dõi.

Bước 5: Cấu hình cảnh báo (Alert)

Thiết lập cảnh báo trong panel:Trong cửa sổ chỉnh sửa panel, chuyển sang tab Alert.

Tạo rule cảnh báo:

Đặt điều kiện cảnh báo, ví dụ: nếu sử dụng CPU vượt quá 90% trong 5 phút liên tục.

Chọn thời gian đánh giá (evaluation interval) và thời gian chờ (for).

Cấu hình thông báo:Chọn các kênh thông báo như email, Slack, hoặc webhook.

Lưu lại:Kiểm tra và lưu rule cảnh báo.

 Hướng dẫn sử dụng Zabbix để giám sát CPU

Bước 1: Cài đặt Zabbix

Tải về và cài đặt:Truy cập trang chủ Zabbix (zabbix.com) để tải phiên bản Zabbix phù hợp. Thông thường, bạn cần cài đặt:

Zabbix Server: Quản lý và thu thập số liệu.

Zabbix Agent: Cài đặt trên các host cần giám sát để gửi số liệu về server.

Cài đặt database:Zabbix sử dụng MySQL, PostgreSQL hoặc SQLite để lưu trữ dữ liệu. Cấu hình thông tin database trong file zabbix_server.conf.

Bước 2: Cấu hình giao diện web Zabbix

Cài đặt giao diện web:Sau khi cài đặt server, truy cập đường dẫn web (ví dụ: http://your-server-ip/zabbix) và làm theo các bước hướng dẫn cấu hình ban đầu, nhập thông tin database, tài khoản admin, v.v.

Đăng nhập:Sử dụng tài khoản admin để truy cập giao diện quản trị của Zabbix.

Bước 3: Thêm host giám sát CPU

Thêm host mới:Vào mục Configuration → Hosts và nhấn Create host.

Nhập thông tin host:

Đặt tên host và nhập địa chỉ IP.

Gán host vào nhóm thích hợp.

Gán template giám sát:Chọn template phù hợp như Template OS Linux hoặc Template OS Windows để tự động theo dõi số liệu CPU, bộ nhớ, disk, … Zabbix sẽ thu thập số liệu từ Zabbix Agent cài đặt trên host.

Bước 4: Kiểm tra và xem số liệu thu thập

Theo dõi dữ liệu:Sau khi host được thêm và agent gửi số liệu, vào mục Monitoring → Latest data hoặc Graphs để xem biểu đồ hiển thị số liệu CPU theo thời gian.

Kiểm tra trạng thái:Đảm bảo rằng số liệu được cập nhật thường xuyên và chính xác.

Bước 5: Thiết lập trigger và cảnh báo

Thiết lập trigger:Trong Configuration → Hosts, chọn host hoặc template tương ứng, sau đó chuyển đến mục Triggers.

Tạo trigger với điều kiện, ví dụ: “Nếu CPU usage vượt quá 90% trong 5 phút”.

Cấu hình hành động (Actions):Vào Configuration → Actions để thiết lập các hành động khi trigger được kích hoạt. Bạn có thể cấu hình gửi email, tin nhắn SMS, hoặc thông báo qua các kênh khác.

Kiểm tra và tinh chỉnh:Thử nghiệm trigger bằng cách tạo tải cao cho CPU và kiểm tra xem hệ thống có gửi cảnh báo đúng như mong đợi hay không.

Bước 6: Tinh chỉnh dashboard và báo cáo

Tùy chỉnh dashboard:Sử dụng các widget có sẵn trong giao diện Zabbix để tạo dashboard hiển thị các chỉ số quan trọng như mức sử dụng CPU, load average, và các biểu đồ xu hướng.

Báo cáo:Tạo các báo cáo định kỳ để theo dõi hiệu suất và phát hiện sớm các vấn đề có thể xảy ra.

Phương pháp sử dụng CPU pinning để đảm bảo các ứng dụng sử dụng lõi CPU tối ưu nhất.

CPU pinning trên Linux

Sử dụng lệnh taskset

Bước 1: Xác định PID của tiến trình cần gán:Dùng lệnh ps aux hoặc htop để tìm PID của tiến trình.

Bước 2: Gán CPU affinity cho tiến trình:Sử dụng lệnh taskset để chỉ định các lõi CPU cho tiến trình. taskset -c 0,2,4,6 <PID>

 Lệnh trên gán tiến trình có PID tương ứng chỉ sử dụng các lõi 0, 2, 4, và 6.

Bước 3: Xác minh lại cấu hình:Kiểm tra CPU affinity bằng lệnh: taskset -p <PID>

 Đảm bảo rằng tiến trình đang chạy trên các lõi đã được chỉ định.

CPU pinning trong môi trường ảo hóa và Container

Trên KVM/QEMU (Máy ảo)

Bước 1: Chỉnh sửa file cấu hình XML của VM (thông qua libvirt):Mở file cấu hình của máy ảo, tìm mục <vcpu> và chỉnh sửa thuộc tính để cố định các lõi.

Bước 2: Cấu hình thuộc tính cpuset:Ví dụ, thêm thuộc tính như sau: <vcpu placement='static' cpuset='0,1,2,3'/>

Điều này sẽ gán máy ảo sử dụng các lõi 0, 1, 2, và 3.

Bước 3: Áp dụng thay đổi:Sử dụng lệnh virsh define <file.xml> để cập nhật cấu hình máy ảo.

Trên Docker (Container)

Bước 1: Khi chạy container, chỉ định các lõi CPU cần sử dụng:Sử dụng tham số –cpuset-cpus khi khởi chạy container. docker run --cpuset-cpus="0,1" <image>

Container này sẽ chỉ chạy trên lõi 0 và 1.

Thông qua việc thực hiện những phương pháp tối ưu hóa này, bạn sẽ cải thiện đáng kể hiệu suất VPS của mình, tối ưu hóa tốc độ xử lý và khả năng phản hồi của hệ thống.
