There are 141 tips in the FreeBSD tips file that is displayed by fortune every time you log into a FreeBSD system. root@geonosis:~ # grep -E '^%' /usr/share/games/fortune/freebsd-tips | wc -l 141 Most of the time, I know the tips very well. Sometime, however, I do learn a new thing. Today I Learned that To set a quota of 10 GB for the user named foo on a ZFS dataset, run the following command: # zfs set userquota@foo=10G pool/home/foo The zfs userspace command can display the quota and current space usage: # zfs userspace pool/home/foo To unset a quota, assign "none" as the value. -- Benedict Reuschling bcr@FreeBSD.org This is actually two tips in one. First, is the userquota in a filesystem, and the second one is how to see these quotas, which I had no idea about. So I tried running it on one of my larger systems root@geonosis:~ # zfs list genomic/abi/proj/cfdna NAME USED AVAIL REFER MO - Music Monday: Bzdig Zinvor / Little Soldier by Armenian Navy Band

I can’t sleep. Let me rephrase that — I am so tired, that I can’t even sleep. I have spent the last two weeks upgrading and reconfiguring the infrastructure at ABI, while at the rest of my time, trying to answer the question “what do I need to be independent on the internet?”. I still don’t have a complete answer, but something is moving towards that direction. I applied for an ASN, and did the payments, now just waiting for my paperwork to go through. Let’s see how it goes. The last couple of months have been really interesting. I start seeing changes that I both like and hate at the same time. And well, what should I do if I can’t sleep? blog about these changes. These are not good always good changes, like I’ve said, some of them I do indeed hate, but most of them should be fine. Last year I got a Valve Steam Deck. Actually, I kind of “won” a Steam Deck? One of our projects was over-b - https://antranigv.am/posts/2025/10/1152/

There’s a lot of work that needs to be done on Jailer. To start with, I have finally decided on the release model. The main development branch will be main, similar to FreeBSD, and then the releases will be tagged. I’m not sure how I feel about branches, as I don’t want to have any kind of LTS versions, but I might need to understand if there’s anything missing in FreeBSD that I would need. Another problem that I have right now is the fact that we don’t have a Port. I’m not happy with Jailer enough to make a Port for it, but maybe in the coming days. Fix the Git stuff that I don’t care about but I should Create a stable non-development version/tag Create more lists like this, because, let’s be honest, no one can work without lists. I do wonder if I can pull an all nighter and finish everything that I hope to finish. Lets see. - https://antranigv.am/posts/2025/07/1120/

Sometimes all I need to do is sudo tmutil listlocalsnapshots / \ | grep TimeMachine \ | cut -d . -f 4 \ | xargs -I% sudo tmutil deletelocalsnapshots % And suddenly I have like 70GB of more storage on my Mac. I wish macOS was less… black magic-y. - https://antranigv.am/posts/2025/07/1110/

Sometimes, when I have a long running process on my computer, like scp , rsync or curl I need to know when it’s done, so I don’t check the terminal every minute. That’s when I realized that this is a perfect fit for Apple Script and pwait . Basically, it looks something like this: pwait `pgrep xargs` \ && osascript -e \ 'display notification "Extraction Done" with title "large xargs"' Now I can go back to work, and I don’t have to check if the job is done every minute. A notification will appear when it’s done. For remote jobs, I have realized, that I can send a notification to myself, kind of like a self-hosted Pushover, using XMPP, I don’t want to go into the details, but that seems like to be a good solution as well. Maybe I should just use Pushover anyway. - Analyzing FreeBSD’s Package Mirror GeoDNS

One of the things that makes FreeBSD an amazing operating system is its package manager, pkg(8) . Many people will keep arguing with me saying that apt or pacman is better, but pkg has some of the best features out there. Don’t even get me started on number of packages. A friend was telling me “but how can I use FreeBSD when you have 1/3rd number of packages that Debian has?”. Again, this is a lie. While Debian has 80K packages, each software is divided into -doc and -dev , while on FreeBSD a simple pkg install will install everything that a package needs. But let’s not talk about how awesome FreeBSD’s pkg is, let’s talk about it’s issues. Couple of years ago, I noticed that downloading from FreeBSD package mirror was veeeeeery slow. Turns out that based on GeoDNS Armenia was connecting to the South African package mirror pkg0.jinx.FreeBSD.org by default. Lucky for me, there was a packag - Migrating to FreeBSD -CURRENT with pkgbase using Boot Environments

Couple of months ago I got my sister a MacBook Air with the new M4 chip, and she was happier than ever. However, I was the happiest, as she gave me her old MacBook Pro 2015. As always, I installed FreeBSD on it, it was FreeBSD 14.2-RELEASE at the time, installed the required drivers, attached a Thunderbolt 3 to Ethernet adapter to it (thank you to whoever made it work via the bge drivers) and… nothing. It’s been sitting on the floor for months now. Last week I decided I’m going to do my FreeBSD work again. I have a todo list with 20+ action items in them. But first thing first, I need a -CURRENT machine so I can do my development. So, here’s a simple guid on how to migrate to FreeBSD -CURRENT using PkgBase. First we need to setup the pkgbase repo, so pkg can use it. I will be using pkg.FreeBSD.am , which is my regional pkg cache, but other than that, everything is pretty standard. root@m - https://antranigv.am/posts/2025/06/1087/

A while back I needed to get the input voltage from one of our UPSes, so I used bsnmpwalk(1) to get the information needed and ran it in a script with a loop and sleep. Running it in tmux(1) , of course. #!/bin/sh lastoff="maybe" while true; do inpvol=$(bsnmpwalk -o quiet -s public@172.20.42.101 1.3.6.1.2.1.33.1.3.3.1.3) [ $? != 0 ] && \ curl -s -X POST \ https://api.telegram.org/botXXX:YYY/sendMessage \ -d chat_id=-ZZZ \ -d text="Something is wrong with the SNMP server" [ "${inpvol}" -lt 200 ] && \ curl -s -X POST \ https://api.telegram.org/botXXX:YYY/sendMessage \ -d chat_id=-ZZZ \ -d text="Power seems to be off. I see Input Voltage as ${inpvol}" && \ lastoff="true" [ "${inpvol}" -ge 200 ] && [ "${lastoff}" == "true" ] && \ curl -s -X POST \ https://api.telegram.org/botXXX:YYY/sendMessage \ -d chat_id=-ZZZ \ -d text="Power back on. I see Input Voltage as ${inpvol}" && \ lastoff="false"
