VADOSWARE is a personal blog at vadosware.io about programming and systems. Since 2017, 22 different Hacker News readers have linked it 157 times, most often “Paxosmon: Gotta Consensus Them All (2018)”. It is still writing: the last post was on 2024-12-28, and you can follow it by feed.
Too few sampled comments (8) to say how often HN recommends it.?
Why HN links it
HN readers link VADOSWARE for a comprehensive overview of Paxos-family consensus algorithms and a deep write-up on optimizing Postgres on ZFS. Comments are mainly citations and praise for these posts.
Summarised by Claude from a sample of 8 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
Professional (software) yak shaving, writ large. No part of the software stack is left unshaven.

For those who might choose to run their own email these days, you don't have to postfix + dovecot: https://github.com/foxcpp/maddy https://blitiri.com.ar/p/chasquid/ These options are much easier to set up, will do things like generate DKIM for you, etc. I talk about this a lot[0]. There are positively awesome tools for email out there. [EDIT] - Since I'm repeating myself I've collected all the options into a post[1…

HN discussionI've actually run into some data loss running simple stuff like pgbench on Hetzner due to this -- I ended up just turning off write-back caching at the device level for all the machines in my cluster: https://vadosware.io/post/everything-ive-seen-on-optimizing-... Granted I was doing something highly questionable (running postgres with fsync off on ZFS) It was very painful to get to the actual issue, but I'm glad I…

HN discussionIt’s been a a long road but I’m finally at a point where I can definitively sat that this advice is some of the best you can give anyone in or out of tech. Writing about software I’m building, errors I run into, and situations I get into (and often stumble through) has been huge for my own development and my career ( https://vadosware.io ). Doing this has led me to habitually bite off more than I can chew which seem…

HN discussionJust checking in to say I'm loving my Oryx Pro ~1 year later. It's been a fantastic system (I wrote about it when I first got it[0]), and although I use it more as a desktop (it sits on my desktop attached to two monitors with the lid closed) it has been a workhorse for me. The software and drivers also work fantastically, and are open source -- I've even contributed a line or two. BTW I use arch :). But I mention t…

HN discussionWell I think that's more of a cost question -- AWS can get expensive pretty quickly. Three t2.micros (one coordinator, 2 nodes) are absolutely pitiful in terms of processing power but that's already ~$30/month when you could get a way beefier machine on Hetzner whether dedicated or cloud (also Scaleway[0]). I'm a fan of Hetzner because I think their cheap dedicated machines are worth the operational costs for me, an…

HN discussionIf you can find the time to get up to speed on Kubernetes, I would say do it. I actually have a weirdly similar setup to you (I run on Hetzner and used and still use ansible), and I've written about it, most recently when I switched my single node cluster to Ubuntu 18.04 [0]. In the past I've also run a single node kubernetes clusters on CoreOS Container Linux, Arch, and back to CoreOS Container Linux in that order,…

HN discussionSo I'm actually doing this right now, I write about it on my blog. None of the apps I've written have hitten any kind of crazy traffic peak, so I started wondering why the hell I was using postgres or other database types after reading https://www.sqlite.org/whentouse.html . Seeing how simple SQLite has been for me to use has inspired me to write a bunch of dead-simple good-enough approximations for other tools that…

HN discussionIt's not that simple. Here's an overview on paxos/raft consensus algorithms: https://vadosware.io/post/paxosmon-gotta-concensus-them-all/ and even that is incomplete and not necessarily describes trade-offs well. Submitted generalized solution is a better point to start experimenting from.

HN discussionAaaand self promotion: https://vadosware.io/post/the-cure-for-impostor-syndrome-is-... tl;dr - Stop claiming to be an expert at things you haven't delved into deeply. Conversely, if you've delved into a subject deeply, there's a high chance you won't feel like an impostor. If you don't have time (or resources) to delve into something deeply, and understand thoroughly, accept that fact and move on.

HN discussionAlpine is one of the unsung heroes of the container world. It's insane how much value Natanael Copa has created & shepherded over the years (decades?).
