Готовим слайсы в Go: подробно о динамических массивах, строчках и ускорении

Привет, Хабр! Меня зовут Владислав Белогрудов, я работаю в команде разработки и сервисов управления в YADRO. Мой текущий проект — информационная система на Go. В рамках проекта я подробно изучил, как работать со слайсами — одной из самых популярных структур в Go. На первый взгляд, использовать ее достаточно просто, но, когда берешься писать код, возникает много вопросов: как передавать и изменять слайсы, насколько большими их делать и другие. Под катом рассмотрим, что такое слайсы и string (строки) изнутри, как использовать их с sync.Pool для ускорения — без «внутренностей» последнего, но с точки зрения клиента. Расскажу о полезных трюках, приведу значения измерений производительности и познакомлю с альтернативными решениями.

Kotlin Coroutines под капотом: отмена корутин

В прошлой статье я разобрал как работают корутины под капотом, однозначно рекомендую ознакомиться прежде чем закапываться дальше. В этой статье мы разберем такую сущность как Job и как на самом деле под капотом отменяются корутины, в общем будет интересно, погнали!

Finally, all cleaned, repaired, cables plugged in, routed, grouped, restrained, and tidied. It really is a beautiful piece of German engineering.
#workstation
#computer
#internals
#teardownfixrebuild2025
#bequiet

Final shot of the finished (new) cable arrangement on the rear-side panel of the workstation. The cables are less tightly bound and flow more naturally now, giving it a more organic feel. The lines are curved, grouped neatly, and with far less in the way of cable ties, velcro straps, and other bindings. The straps that are visible are grey, and they say "be silent!" in white on them. It is a more white, cleaner, look, from the beginning. Note that this will not really be seen almost ever - only by me, when I open the side panel for maintenance. I STILL need it to be neat for me.Final shot of the internals of the processor side of the case (open). The CPU cooling unit has been inverted, so now the bulbous little fan is on top of the upside-down black coffin-shaped geometric shape. The radiator hoses, in webbed grey with white stripes, look even more neat than before as they lead away below the white "deck" and the white floor paneling of the case (though one is absent, revealing a well-perforated white metal mesh below). The black radiator (left) stands tall and clean. Two black fans looking down upon the scene from above. The GEFORCE RTX card (card? more like a BLOCK of metal!) by msi is still inverted. All very high contrast and primarily white with black detail. The cabling is grouped similarly, though neater, than before. Even the few traces of colour at the edges have been tidied somewhat. It is quite a spacious case, with the motherboard taking up only two thirds of the available space. Spartan. Spacey. Dave, we are ready for boot!Outside of the closed (thankfully, finally) beast. A large white prism of a thing with pleasing beveled edges and corners. Built of solid steel, it weighs quite a lot. It stands on two helicopter-like skids, and thin, black, perforated, "breathing" strips run down each side of the front. The front bears a small logo text discretely, towards the base, in brushed aluminium. It says, in a tasteful lowercase font "be quiet!". The front panel is a large white metal mesh panel, the holes round, revealing behind it a honeycomb shape of metal lattice stucture. It really is an attractive, minimalist, case.

Looks like a tiny set for a sci-fi stop-motion feature!
#workstation

#bequiet

The "guts" of the computer, the L-shaped frame holding the motherboard and rear case fan, lays on my desk ready for maintenance work. There is one stick of RAM attached to the board. Still all black details with mostly white, except for the "be silent!" logo, which is white and orange. The black, 9-bladed, serrated, fan, is designed for extremely quiet operation (but not quiet enough for me - more on that another time). The case panels have well-designed hand-tightened screws (black) and the removable accessory panels are solid steel, painted white, and perforated with black holes for good airflow. It's all very spacey.Mid-distance shot of my workspace for the "operation". It shows the L-shaped "set", a white, spring-balanced folding desk lamp with inbuilt magnifier shining down upon it, and in the background the now-hollow computer case. Cleaning supplies and various tools are visible to the right, such as isopropyl alcohol, tweezers, a green microfibre glass cloth, and other bits and pieces. It really does look like I'm about to start shooting the new Wallace And Grommit "in space" edition.The L-shaped section stood up on its side (such that the L shape itself lays flat on the white desk) so that it now seems to resemble two adjoined walls of a set from a tiny sci-fi film. The stark black circuitry and white and aluminium panelling is quite reminiscent of the opening scenes of Star Wars: Episode IV - A New Hope. A natural toned lamp illuminates the "set" from above.

Unplug all the cables and snip the cable ties from all the harnesses... (I always take photos so I know where things were originally)

#bequiet

My left hand holding back three sets of webbed black power cables and connectors that were feeding into the graphics card. The CPU has been removed, as has the RAM, revealing rows of pins and capacitors beneath the CPU socket. This is but one of several reference shots I take during any major operation to make it easier for me to retrace my steps should I need to.Reverse side, where before there were cable ties and tightly bound runs of straight cables, most have now been disconnected, ties cut out, and they hang freely, ready to allow me to remove the main sabot of the mainboard.The L-shaped metal bracket which holds the motherboard, rear sockets, and the rear case fan, now rests in my hand, still connected by a few power cables at the base. This truly is like surgery. The near-bare skeleton frame of the computer resembles bones. Two fans are still in place at the underside of the top. They are also black, as is the 420-size radiator, which takes up the entire front wall of the tower (fans are on the other side of the radiator). The room is grey with white trims and it is comfortably bright daylight.

Understanding UEFI: How It Works and Its Internals

The Unified Extensible Firmware Interface (UEFI) is a modern firmware interface between a computer's operating system and its hardware. Designed to overcome the limitations of the older BIOS (Basic Input/Output System), UEFI offers enhanced functionality, improved performance, and better security. Here’s a comprehensive look at how UEFI works and its internals.

I was planning on using for my next project, and I wanted a bit of crash course on , and came across this absolutely fantastic series of tutorials on by Omer Rosenbaum. If you want to dig into git in more detail, these are a great place to start. youtu.be/fWMKue-WBok?si=yygfpQ
