When you try to checkout git repository, it's possible to face this kind of error: error: You're on a case-insensitive filesystem, and the remote you are trying to fetch from has references that only differ in casing. It is impossible to store such references with the ‘files’ backend. You can either accept this as-is, in which case you won't be able to store all remote references on disk. https://yantonov.com/post/2025-12-07-what-is-intelligence/ Sun, 07 Dec 2025 00:17:59 +0100 https://yantonov.com/post/2025-12-07-what-is-intelligence/ Book https://yantonov.com/post/2025-12-06-congnitive-bias/ Sat, 06 Dec 2025 22:54:56 +0100 https://yantonov.com/post/2025-12-06-congnitive-bias/ A brief and visual description of cognitive distortions.

How to fix it: open powershell select home directory wsl -d DISTRO --cd ~ where DISTRO is the name of the distribution, that can be obtained wsl -l Source https://yantonov.com/post/2022-07-10-about-rfc%5Cadr%5Cdesign-docs/ Sun, 10 Jul 2022 14:04:28 +0200 https://yantonov.com/post/2022-07-10-about-rfc%5Cadr%5Cdesign-docs/ Nice article about the topic. https://yantonov.com/post/2022-06-04-about-static-types/ Sat, 04 Jun 2022 20:04:06 +0200 https://yantonov.com/post/2022-06-04-about-static-types/ A couple of notes about static and dynamic types Literature review on the benefits of static types This is how science happens https://yantonov.com/post/2022-05-12-usecase-for-git-refs/ Thu, 12 May 2022 10:39:49 +0200 https://yantonov.com/post/2022-05-12-usecase-for-git-refs/ Here you can read about an excellent example of how to use git refs in practice. a nice way to track the experiments (ML related for example). https://yantonov.com/post/2022-05-11-link-imbalance/ Wed, 11 May 2022 17:18:48 +0200 https://yantonov.com/post/2022-05-11-link-imbalance/ Interesting reading about link imbalance: Metastable Failures in Distributed Systems Solving the Mystery of Link Imbalance: A Metastable Failure State at Scale https://yantonov.com/post/2022-04-07-move-wsl-to-another-drive/ Thu, 07 Apr 2022 10:22:12 +0200 https://yantonov.com/post/2022-04-07-move-wsl-to-another-drive/ Here is a nice instruction how to migrate wsl to another drive. A couple of nuances: When you export the image there is no need to define the version of WSL. But for the import you should do it (if you use version 2 for example), by using the version parameter, otherwise, you will get a confusing error about an incorrect parameter. To define the default user you should use the command that may vary depending on the os version. https://yantonov.com/post/2021-10-04-github-repositories-that-help-you-to-prepare-for-the-next-interview/ Mon, 04 Oct 2021 12:33:47 +0200 https://yantonov.com/post/2021-10-04-github-repositories-that-help-you-to-prepare-for-the-next-interview/ Here is the list of general/algo/system design questions: coding-interview-university build-your-own-x tech-interview-handbook how-to-secure-anything javascript-algorithms how-web-works algorithms-javascript system-design-primer awesome-interview-questions olshansk-interview Golang 11. learngo Javascript 12. clean-code-javascript 13. javascript-questions source https://yantonov.com/post/2021-08-10-geometric-deep-learning/ Tue, 10 Aug 2021 02:15:23 +0200 https://yantonov.com/post/2021-08-10-geometric-deep-learning/ Geometric deep learning course.

By default Windows uses Powershell not bash, but you may prefer to explicitly choose bash as a shell. See Github action documentation You can find some details about using Powershell here https://yantonov.com/post/2021-04-12-forbid-using-a-function-in-python/ Mon, 12 Apr 2021 10:59:36 +0200 https://yantonov.com/post/2021-04-12-forbid-using-a-function-in-python/ Here is an example of flake8 plugin that prevents you from using numpy random fn.
