GitHub (and many others) exposes mail-style patches at .patch URLs. If you download one of those patches and feed it to GNU patch , diff-shaped text inside the commit message can be applied as if it were part of the real patch. It matters (to me) because wget / curl plus patch is not some exotic lab setup. It is a very old, very ordinary way to move a patch from one machine to another.
We have a server with Docker Swarm initialized. A few services are running on it. We need to scrap metrics to prometheus and we want it to use direct connection to the services without going through a load balancer. I’ve spent a bunch of time figuring out how to do it, so here is a tutorial just for my future self. There are several ways to scrap metrics with service discovery:
You know the feeling of watching your post quickly drowning in the Newest section of Hacker News, right? It seems like pure, chaotic luck. Or is it? I tried to crack the code of successful submissions. I built a tool that parses Hacker News every two minutes and logs the state into the database. The program has been working for 14 days so far. For the latest two weeks, there were 13846 stories,…
I have always wanted to build a blog, but for a long time, I have been postponing it. Well, I guess I thought it was difficult to build a blog. Turns out, even if you self-host it, it’s not that hard. I decided to finally create it one day, and I had a few criteria: No fancy admin panels. I want to write markdown and deliver it as is. Without sacrificing the privacy of visitors, I should be…
I’ve just watched the talk «Nailing Your First Launch» (MicroConf Starter 2018) by Adam Wathan and I took notes that I’d like to share and re-visit them in the future. Some of them are just text from his screens, some thoughts are mine. But don’t let me steal the video from you by providing a digested summary. In my humble opinion, the main idea of watching talks or reading…
Sometimes I do fork repositories and do some tweaks here and there for my personal needs which ain’t really going to be merged into the upstream repository. One thing that used to concern me is that I needed to manually rebase my changes onto the upstream to have new goods but keep my changes on top of them. Fortunately, GitHub Actions supports the schedule trigger for workflows and this is…
TL;DR Mark — a tool for syncing your Markdown with Confluence Devil’s Playground Oh man, I was so frustrated when I was trying to edit docs in Confluence, and it broke all my text, trying to adjust any tags led to breaking the text even more. I felt the same when Slack introduced their Wysiwyg editor that solved problems that never existed, but at least they added an option to disable it.
Have you ever thought how good it would be to have a help message for your shell script that you wrote a month ago and already forgot what it is supposed to do? Yeah, there is always a way to show a message using cat (meow) or a bunch of echo calls. But there is a neat trick. Add your message with all the required information on top of your file, just right after the shebang.
