Programming

I’m a big fan of the way Go does zero values, meaning it initializes every variable to a default value. This is in contrast with the way other languages such as, say, C behave.

(This article has been graciously translated to Russian here. Huge thanks to Akhmad Karimov.) I wrote a brief introduction to Go modules and in it I talked briefly about Go modules proxies and now that Go 1.

This post is also available in other languages: Russian: Введение в модули Go Uzbek: Go modullariga kirish The upcoming version 1.11 of the Go programming language will bring experimental support for modules, a new dependency management system for Go.

Update: much of this article has been rendered obsolete by changes made to Go modules since. Check this more recent post that’s up to date. Had some free time in my hands, so I decided to check out the new Go modules.

So we created a concurrency-safe LRU in the last post, but it was too slow when used concurrently because of all the locking. Reducing the amount of time spent waiting on locks is actually not trivial, but not undoable.

In my job, I often catch myself having to implement a way to keep data in memory so I can use them at a later time. Sometimes this is for caching purposes, sometimes it’s to keep track of what I’ve sent some other service earlier so I can create a diff or something.

I’ve just spent much more time than I ever wanted to get this right, so here’s how I did it for future reference. I have a function that returns an http.

Whenever someone posts anything related to the Go programming language on Hacker News, it never takes long before someone complains about error handling. I find it interesting because it is exactly one of things I like the most about Go.

I’m back from a trip to a customer. How was it? Okay. I got more snow that I expected on the way there, so the drive wasn’t much fun. Then again, a part of the trip goes through a beautiful forest that was worth everything else.
