andrestc··on Ask HN: Could you share your personal blog here?
Mostly about Go and OS stuff but haven't updated in a while. http://andrestc.com
andrestc··on Meta to ask many managers to become individual contributors or leave
The technical bar for EMs at Meta is quite high.

andrestc··on Facebook wants up to 30% of fan subscriptions vs Patreon’s 5%
"The policy document attained by TechCrunch shows Facebook plans to take up to a 30 percent cut of subscription revenue minus fees, compared to 5 percent by Patreon, 30 percent by YouTube, which covers fees and 50 percent by Twitch."

Looks on par with other providers.

andrestc··on Show HN: Open-sourcing my wedding website on my first anniversary
How hard would it be to set up a backend payment service to receive $$ for gifts?
andrestc··on Microsoft cURLs too
This is amazing! Thanks for sharing
andrestc··on A regression is the kernel not giving the same result with the same user space
It's not as strong as the kernel. Go does not break APIs but may break undocumented behavior.
andrestc··on Using cgroups to limit I/O
Author here.

>Also, while this article is quite rosy-eyed about cgroupv2, there are many many issues that mean that cgroupv2 is not really usable by container runtimes today -- despite what systemd might be trying to do with their "hybrid mode". A friend of mine from the LXC community gave a talk about the wide variety of issues that occur due to cgroupv2's weirdly restrictive API[3]. The blkio writeback cache limits are very useful, but they're really not worth the pain of breaking how container runtimes have to work.

I knew there are some problems with cgroup v2 but haven't quite looked into it. I'm going to watch the talk and probably add a note about that. Thanks!

>You can mount a single cgroupv1 hierarchy with multiple controllers attached to it (that's what 'cpu,cpuset' are), which then could (in principle) know about it each other. But they don't, since a lot of the cgroupv2 code is locked behind cgroup_on_dfl(...) checks. That's interesting, I didn't know about that! I'll add a note to the post.

andrestc··on Perl as PID 1 under Docker
Nice writeup. Interesting enough, SIGKILL does not work from inside the container: https://andrestc.com/post/killing-container-inside/.
andrestc··on Ask HN: Starting blogging when you're not an expert?
Thats the precise reason that I've started my blog, https://andrestc.com. I'm writing about things I'm learning while studying several topics.
andrestc··on Reading OpenBSD source code daily
May i suggest maintaining a repo on github with such material? Would be easier to keep up and might bring in some contributions
andrestc··on Ask HN: Which companies have the best blogs written by their engineering team?
I really like the packagecloud one: https://blog.packagecloud.io/

andrestc··on Rack: Open-Source PaaS on AWS
Take a look at tsuru.io.
andrestc··on Kel: An Open-Source, Kubernetes-Based PaaS Built in Python and Go
Tsuru.io is an open source PaaS that provides heroku like deployments and other features!
andrestc··on Three Years as a One-Man Startup
Glad I could help, its not my idea tho... credits to: http://www.abtestingbook.com/
andrestc··on Three Years as a One-Man Startup
> I use split testing for some things but it feels wrong to do this for price

You can do the A/B testing only on the pricing page. For ex, A would display $5 and B would display $10. When the user get to the checkout display always the lower price and tell the user he got a discount. You can measure the % that get to the checkout and the bounce rate at the checkout.
