Yesterday I've mentioned Striff, the tool that finds inconsistencies between documentation and the source code. We installed it already to the EO and it works good. It's free for open repositories. I recommend.

I just released a new GitHub action plugin: terald-action. First, create a new Telegram bot via @BotFather. Then, create a chat with the bot and get chat ID. Finally, add two secrets to the repo and configure the plugin in one of your CI workflows:

steps:
  - uses: actions/checkout@v6
  - run: make
  - if: always()
    uses: yegor256/terald-action@0.1.0
    with:
      token: ${{ secrets.TELEGRAM_TOKEN }}
      chat: ${{ secrets.TELEGRAM_CHAT }}

We need a Java library, similar to Python's seqfile, for EO compiler. It should create a new file/directory in a directory, using the first available number-prefixed name. For example:

Iterator<Path> s = new Seqdir("/tmp", 3).files();
Path p1 = s.next();
assert p1.endsWith("/001-foo.txt");
Path p2 = s.next();
assert p2.endsWith("/002-bar.txt");

Через месяц, 9-го октября, выступлю на SysAdmin 2026, в кластере «Ломоносов» в Москве. Вход свободный, но нужна регистрация. Видео обещают записать, но лучше лично посетить, потому как и кластер и конференция того стоят (наверное — я не был еще ни там ни там). Доклад будет не только про ИИ, но и про людей.

The 6th ICCQ conference has been granted in-cooperation status by the IEEE. Accepted papers will be published in IEEE Xplore and indexed in Scopus. The CfP deadline is about three weeks away, on August 17 — so there's still time to submit your work. This year, Patrick Cousot is our keynote speaker, and our Program Committee includes three ACM Fellows: Doug Lea, Benjamin Pierce, and Philip Wadler. It's the strongest lineup in our six-year history.

Артемий Лебедев убежден: великий русский язык, ежели запретить в нем обсценную лексику, величие свое непременно утратит. Возможно. Однако всему свое время, Артемий, и свое место. Скажем, тело твое без срамного уда тоже красоту свою утратит. Но не станешь же ты выставлять свой орган на всеобщее обозрение в офисе. Потому что воспитание ты получил соответствующее. Любимой женщине похабщину на ушко шептать да в краску ее вгонять — дело полезное, к деторождению ведущее, сам знаешь, не мне тебя учить — для него и прибереги навыки матерщинника. Или же если, боже упаси, в тюрьме окажешься, тоже нецензурную брань вспомнить пригодится, когда за лучшее место на нарах побороться придется. А со зрителями и читателями, большинство из которых интеллектуальной элитой все еще себя считают, давай общаться, оставаясь людьми воспитанными.

Two developers can write almost identical code. But one gets $200/hour, while the other gets $10. Why is that? In this video, from the JEEConf 2017 in Kyiv, I break down how a developer’s “price” is actually formed: what CTOs look at when hiring, why experience can sometimes be devalued, and which signals make you an expensive specialist in the market. This is for those who feel like “I’m doing everything right, but for some reason I’m valued lower.”

If you love Claude Code as much as I do, you may find this new blog post interesting: Help the Agent to Feel. In the article, I argue that without our help a coding agent can't feel the aesthetics of the source code and the elegance of software design. The agent can write correct code better than us, but it can't write it as pretty as we expect. We can and must help him.

Лермонтов (2025) от Бакура Бакурадзе (это который Шультес) доставил эстетическое удовольствие. Смотрел и вспоминал, как учил великий Тарковский: "поэтичность фильма рождается из непосредственного наблюдения над жизнью." Поэтичность родилась. Но не из сюжета, арок персонажей и перипетий — обошлось без всей этой ерунды. Из костюмов, интерьеров, пейзажей и звуков. Звуков! Не cтолько наблюдал, сколько слушал жизнь молодых офицеров середины XIX века. Точно не зря ему Нику дали за лучшую режиссуру. Тарковский был бы доволен. #кино

Can someone create an open source Java library with a JUnit extension to provide tests with an ephemeral (random) TCP port as argument? We need it badly for EO runtime library testing. Should work like this:

@ExtendWith(
  EphemeralResolver.class)
class FooTest {
  @Test
  void f(@Ephemeral int port) {
    // Here we know the "port"
    // is random
    // and doesn't conflict 
    // with other processes
    // and other JUnit tests 
    // currently running
  }
}

The team is busy. Calls are happening. But the real question is: are they actually working or just looking busy? I gave the talk during DevOn Summit 2017 in Delft, The Netherlands, where I break down the four main killers of productivity that exist in almost every engineering team: endless meetings, useless documentation, the strange role of managers, and the illusion of control; and the alternative of how to manage 100 developers without meetings and task assignment.

KaiCode, our annual festival of open source projects, is announcing winners of the 2026 competition (and rewarding some cash to help them grow):

raprogramm/yew-nav-link 6★
Perfect $2048

ahoo-wang/wow 296★
Excellent $1024

choplogic/chop-logic-components 5★
Awesome $512

These projects were selected out of all 153 submitted this year. As you see, popularity didn't matter, but only the quality of code, discipline of development, strictness of testing and delivery pipelines, and the accuracy of documentation. Don't hesitate to give these guys a few GitHub stars, to cheer them up.

Many thanks to nine Jury members, who manually reviewed all 14 finalists. Thanks to the Steering Committee (Alexander Medvednikov and Nikita Sobolev) — they validated the results of the Jury. Thanks to Claude Code — he helped us not to miss important details in every finalist.

You are welcome to submit your open source project to the next year competition!

We've published a new set of benchmarks for Java Stream API: objectionary/sabj25. Unlike all other existing benchmarks, our set covers the entire Stream API of JDK 25. We used these new benchmarks to verify the effect of optimization of Java bytecode by our hone-maven-plugin. Quick conclusion: we can make some Stream pipelines 2x faster.

A common management idea is that people work better when they see the bigger picture: company goals, top-level metrics, strategic objectives, and so on. What’s interesting is that research seems to show the opposite. In many cases, exposing employees to those metrics actually hurts motivation rather than improves it. I just published a #blog post arguing that managers should stop sharing some of these numbers with their teams altogether: Don't Blame the Wheel for Missing a Turn.

What do you think about the indentation in this small Java snippet? If it looks ugly to you—as it does to me—you may appreciate a formatting principle I suggest for any programming language: Monotonic Indentation (unless I reinvented the wheel). The idea is simple: between any two adjacent lines, indentation may increase by exactly one unit. The blog post explains the principle in detail.

It took six months to write the second volume of the Angry Tests book, and today it’s finally published on Amazon. The book goes deeper into building stronger tests, explores many exotic testing techniques, and introduces the concept of Headless Development. If you buy it on Amazon and leave an honest review, I’ll refund 50% of your purchase.

Many thanks to all reviewers, who helped me make it better: Alexey Fedotov, Alexey Sedoykin, Anton Belyaev, Artem Yegorov, Edouard Mangel, Emanuel Trandafir, Gennadii Chursov, Igor Zarvanskyi, Mathieu Ghennassia, Maxim Ivanov, Nikita Vasilyev, Robert Vitonsky, Ruslan Dibirov, and Sergey Karmanovich.

В середине июня несколько экземпляров будет в Москве, заказать можно здесь. Первый том можно заказать здесь.
