Some say @oxide.computer’s series C was to buy and hodl RAM with $100m and the remaining $100m for the pod (yet no Morris Chang yet, tsk tsk)

So I have 128 GB of DDR4 I bought back in 2022. The equivalent today is way more than double the price πŸ˜…

Is there a $RAM ticker? 😭

and i haven’t been inspired to cook or work out in a long time.

things feel off. it’s like i have cognitive paralysis by information anxiety.

is anyone else just finding it hard to learn and explore interesting things these days?

am i doing something wrong?

i have a really great number of interests ranging from technical, to craft, reading, languages, writing. but i can’t seem to spend more than 10 minutes on anything before i fatigue.

i also thought it was a bit strange to pay for a search engine, then i remembered how all the other (good and not just private google wrapper) search engines make money.

and the search experience on kagi has just been really good.

i'm writing these silly little microblog entries to just get into some habit but not having to plan and commit to a big polished blog post.

It's all very bad, and I don't want to take away from that reality when I say this, but we've had an awful lot of "I told you so" moments and I'm tired of not saying that so I'm saying it.

4/ Fuzzer runs 24/7 now, with minimized corpora pushed to our bark-qa repo alongside test vectors used throughout Bark's development. More targets comingβ€”serialization/deserialization expansions, method-level fuzz targets. Full writeup: https://blog.second.tech/fuzzing-bark-for-server-reliability/

1/ We caught a capacity overflow bug in Bark before it ever hit a user, thanks to the fuzz testing @luca0x46 has been running around the clock. A malformed VTXO could have requested an arbitrary vec size during deserialization, triggering a panic. Now it's patched.

I love highveld thunderstorms. Hearing a bunch of cars having their alarms suddenly go off because the thunder is literally causing enough vibration πŸ˜…

totally valid workflow. obsidian sync is just one way of financially supporting obsidian and with a bit more convenience / not forgetting to manually commit and push

Ah this is awesome! So is this only sync, or does it act as a kind of daemon you can use with the CLI?

Most programmers are taught that L1 is the β€œtop level” cache on x86.


It’s not quite true anymore!


Intel calls it the Decoded Stream Buffer (DSB), AMD the OpCache.

Only enough room for ~4,000 micro-ops, but there are interesting ways to take advantage of it.
