Идемпотентность — звучит сложно, говорят о ней редко, но это касается всех приложений, использующих API в своей работе. Меня зовут Денис Исаев, и я руковожу одной из бэкенд групп в Яндекс Такси. Сегодня я поделюсь с читателями описанием проблем, которые могут возникнуть, если не учитывать идемпотентность распределенных систем в своем проекте.

There's a graphics trick that used to be widely known that has now probably almost vanished from the graphics consciousness - you can do rotations by applying three shears in a row. This should surprise you! It surprised me. And it re-surprises me every time I remember it.

I think sound is a dramatically underutilized way to communicate with the user in modern software tools. Using sound for a notification is just annoying, but using other properties (pitch, timbre, length, etc) or producing varying drone sounds across time presents new ways to passively inform users of things. A classic example of this is fan sounds alerting users that their computer is under heavy load, and perhaps something is going wrong. As modern fans get quieter, computer programs should offer similar interfaces to provide all kinds of information.

A paper about the old NoteCards program. I printed it out on an office printer and read it, unlike most other papers I saved in this Betula.

Organizing data in notecards, linking them. Notecards are not scrollable. Fileboxes and Browsers, special notecards. They state the system is programmable, but no detailed description of programmability is given. Interface is not really detailed.

Overall, this paper is not enough. I shall look for more.

Applying The Blue Angel Criteria To Free Software

A good snippet. I used it at work.

func track(name string) func() {
    start := time.Now()
    return func() {
        log.Printf("%s, execution time %s\n", name, time.Since(start))
    }
}

func main() {
    defer track("main")() // do not forget about the second parentheses
    time.Sleep(2 * time.Second)
}

Lentils и lenses родственные слова. В русском когда-то линзы чечевицами называли.

Throughout history, people have bathed in public rather than in private. Should we bring back the public bathhouse for the sake of sustainability?

I can hardly imagine myself using one daily. I'm late for work every day,having to go to a yet another place just to clean my meat case sounds ridiculous. Also, I wouldn't particularly enjoy bathing in public. And let's not forget about hygiene. Modern people barely manage using public toilets, and you expect them to manage something even more complex?

But energy-wise, communal bathing is indeed effective.

We're a friendly community creating a digital corner pub.

Our goal is to enable more people to use free software, have secure digital communications, and to take control over their private data.

We host online services for you and all the people you love. We do this transparently and democratically.

A 16 color palette for dichromats and trichromats

Ametameric is as a system palette that provides the standard CGA/ANSI colors accomodating various forms of human color blindness/color vision deficiencies. 16 colors (including white, black and two grays) that all provide sufficient contrast for all common types of color vision. When working as intended, TUIs made to work well with the system colors (rather than 256/true color) should become accesible for color vision deficient users without further tweaks needed.

The main reason nerds are unpopular is that they have other things
to think about. Their attention is drawn to books or the natural
world, not fashions and parties. They're like someone trying to
play soccer while balancing a glass of water on his head. Other
players who can focus their whole attention on the game beat them
effortlessly, and wonder why they seem so incapable.

Back in 2008, I wrote some software for fun to generate various optimized walking mechanisms. And when I also picked up some electronics and wood working skills in more recent years, I was able to turn one of these mechanisms into an actual wireless walking wooden coffee table: the Carpentopod. This post briefly covers this project from start to end.

The 1OPS principle is the single principle that had the biggest impact in my entire coding career. I gave some hints about it in a previous post, but I was suggested that it might warrant a post on its own to go more in depth.

There is a single advice I would give to anyone writing software, and specially to great devs : Always optimize your code for your most junior developers. I agree that it is not a very popular advice, but it is the one that, in my experience, give the biggest bang for the buck.
