A very short tale about a pole display and an Open Source operating system. https://jpmens.net/2018/06/19/on-a-pos-pole-display-and-an-open-source-os/ #openbsd
why properly documenting API is hard or "a new candidate for worstly-designed trivial API: SSL_CIPHER_description(3)"
Awesome read about Meltdown protection, crazy kernel stuff and the collaboration between #Illumos, #DragonFlyBSD and #OpenBSD https://blog.cooperi.net/a-long-two-months
Meltdown fix committed by guenther@ https://www.undeadly.org/cgi?action=article;sid=20180221201856 #openbsd

It doesn't work on everything, not even all websites using Font Awesome (you wouldn't believe how many ways people find to implement the hamburger...) but it occasionally pops up in hilarious places
There is a meltdown patch in the snapshots. If you were holding out, testing -current now might be a good time try, you may help find problems. #OpenBSD
#OpenBSD on #armv7 and #arm64 are basically "safe" for the moment.
#Meltdown is only really possible on a not-yet-on-the-market A75 CPU. Plans are being made to separate the page tables on arm64 anyways.
For #Spectre: Our implementation on armv7 flushes the BTB on every context switch, so that isn't a problem. arm64 should be safe for Cortex-A53 cores, which is the majority.
I wrote about why we use a prime number as a length of our test cycle: Continuous testing but with irregular schedule

USB will be great! Finally, a single serial port spec! Say goodbye to that confusing mess of incompatible connectors!

PSA for people who #code:
Looking stuff up does NOT make you bad at coding.
"Not having to look up stuff" is NOT the benchmark for a good coder, especially as coders have to look up stuff ALL THE TIME!
And I don't mean highly advanced stuff, but stuff like "How does division work again?" or "What's that function called?" or my personal favorite "How to I nest for loops in list comprehensions?".
It's ok if you have to look up stuff!
PSA
"my code is ugly" is a stupid ass reason for not making it open source

just because it's not rivaling reading Shakespeare, we can still learn from your thingy

If you use #OpenBSD and I'm not yet following you - reply, boost or like this toot. I want to catch you all.
Might waste an awful lot of your remaining lifetime Show more
