Yesterday, at the SQM lecture about Lines of Code (LoC) metric, we were discussing how much time it takes to create a large software product. Felix at Quora says that it is somewhere around 250 years for a million LoC. I've just counted my numbers for the last 10 years, in 195 repositories. I'm pretty close to a million, but not yet there :) On average, it's 6K per month.

Take a look at a pretty cool Java library just released by one of our guys: xnav. It simplifies XML documents traversing, which usually is done with the help of DOM or XPath. The former is pretty cumbersome while the latter may be very slow, if XML is huge. This library is a decorator of DOM, with an imperative fluent interface. Give this repo a star, help it become popular!

I've never used Git pre-commit hooks, because believed that they, being developer-specific, don't control quality as strong as a CI-side build pipeline. However, today, I've played a bit with the pre-commit tool and found it pretty useful. However, their documentation strongly suggest adding a YAML config file to every repository. That's ridiculous! After some research, I've found out that I'm not the only one with this question: how can pre-commit tool be used for all repositories, avoiding massive duplication of the same YAML configuration, across all repositories? Here is my solution, if you wonder too, posted on SO.

Семь пар нечистых (2018) от Кирилла Белевича, по повести Вениамина Каверина, с Юрой Борисовым и Мариной Ворожищевой — яркий, лаконичный, жестокий и правдоподобный боевик о мужестве и любви, как его производной, а не наоборот, как сейчас модно считать.

The famous Clean Code by Robert Martin must be a starting point of any software developer who cares. It's fun to read, it's full of aggression towards bad code, and it's a trend setter. The #book is classic.

You know, I'm currently writing a book about automated testing (you see a fragment of it). Sometimes it's necessary to quote a webpage, like a blog post of a news article. Some URLs are pretty long and, because of that, look ugly on paper. We are supposed to use URL-shorteners, which usually are hosted services (not always free).

Long story short, I created my own serverless URL-shortener hosted on GitHub Pages: https://github.com/yegor256/jttu (short for "jump to the URL"). Works like a charm and costs $12/year for the domain name. Feel free to add your URLs or simply fork the repository and host on your domain.

Посоветуйте, пожалуйста, хорошее кино или сериал.

While preparing a lecture for the SQM course, I just stumbled upon an interesting 10-years-old study showing that "developers with higher experience tend to introduce most of the self-admitted technical debt." This means, I believe, that senior developers don't care about quality as much as they demand juniors to care about it. By the way, PDF paper you can find with this bot: @scihubot (I'm not affiliated).

Понравился сериал Крылья Империи (2017) от Игоря Копылова. Он про революцию, любовь и смерть. Как оказалось, ни одна из этих женщин по отдельности не сделают мужчину счастливым. Однако, все втроем — вполне могут. #кино

Let's start a new year with a new book. It will be about automated testing and should be finished by the end of January (25% is already done). If you want to be a reviewer of its draft (up to 220 pages), please fill up this form. I will expect your reviews no later than the end of March. Of course, all reviewers will get a free copy of the book, with their names mentioned in the Acknowledgement page.

Can you recommend a technical YouTube blogger to subscribe to?

It's a quote from my blog post about recruiters that I published nine (!) year ago. What changed since then? We still have recruiters. They still abuse the market exploiting our weaknesses. By the way, we have a group where you can show your resume to others and let them criticise it: @resumania (join and try!)

Собираемся записать новогодний 26-й выпуск черно-белого айти, с обзором главных новостей за ноябрь-декабрь, а также за весь год. О чем именно хотелось бы услышать анализ? Присылайте ссылки на новости.

A paper from Meta, recently presented at ESEC/FSE’23, says that in 2023, with the help of their toolkit named SCARF (not open source), they "deleted over 104 million lines of unused/dead code." Does the number sound reasonable to you, keeping in mind that in 2014 they've had just 17 million lines in their repository?

Sometimes it's necessary to test a Java class for its so called "thread-safety" — its readiness to accept concurrent requests from multiple threads and behave consistently. Not all classes are thread-safe. For example, LinkedList and HashMap are not. How do you know that your classes are thread-safe? I released together, a new tiny open source library that helps you make sure they are, by putting your Java object under stress — sending similar requests to it from different concurrent threads.

BTW, thanks to this new testing instrument, a bug was discovered in tojos, a pretty stable library that we've been using for a few years, inside the EO compiler.
