I wrote my own (or rather, had Claude write it), https://github.com/hanwen/runclaude . Mine uses containers, and makes only the git/jj workspace read/write, hiding all credentials …

Yes. The links are to isolated threads on a rail (model) forums (apparently, this publisher markets books/magazines related to railway models). It's hard to see if the individual c…

Curiously, if you look for "geramond verlag betrugsmasche", or "verlagshaus24 betrugsmasche", it will now tell you that there are no indications it is a scam, but "significant orga…

I got tired of the permission prompts and wrote a filesystem/network sandbox so I could skip all permission checks. It works on the same principle as bubblewrap, but has some nicet…

AWS graviton, Google Axion? ARM has better performance per watt, which translates to better performance per $.

interesting article, but now I'm left wondering how the glucose gets to the retina. Why is this easier than supplying oxygen?

That is not quite the right word. For Python, the headcount was moved from the Bay Area (the most expensive place in the world to hire software engineers) to Munich (the most expen…

Is anyone from GitButler reading this? As others alluded, JJ already exists and is a credible successor to Git for the client side. Technical desides aside though: how is this supp…

blaze/bazel was a big improvement over its predecessor (a set of python scripts that generated huge makefiles), but that did not make it free of accidental engineering. The google …

Rob left Google a couple of years ago.

"WarpBuild are still the better option." what makes you think they won't hike the control plane price again? They can turn this knob arbitrarily to put you out of business.

IIUC, on EC2, the disk (EBS)is one service, and snapshots are in another service (S3). Taking a snapshot involves copying the entire disk to S3, while restoring a snapshot pages bl…

Also: did you consider using LVM snapshots?

Thanks for writing the blog post; it was a fascinating read! I was curious about a couple of things: * Have you considered future extensions where you can start the VM before you c…

IIRC it already uses content defined chunking for finding object deltas.

Hi! sorry for not responding to your email, I was swamped. I looked through the sourcecode, but I can only find UI (ie. browser) code. Does this do anything beyond delivering a mor…

don't forget Android.

Both David Chang and his staff are ridiculous. Different parts of the bird take different times to cook, so for food quality, cooking a bird as a whole makes no sense: either the b…

Developer infrastructure at google reported into cloud from 2013 to 2019, and we (i was there) tried to do exactly that: building products for gcp customers based on our experience…

Haskell is another oddball. It was for a hardware project that used the to-be-auctioned analog TV RF spectrum for a new WAN standard. It was canceled when it became clear the spect…

Hi, I wrote zoekt. From what I understand valtown does, I would try to use brute force first (ie. something equivalent to ripgrep). Once that starts breaking down, you could use la…

github uses something called babeld (just telnet to github.com port 22; the version string is printed immediately.)

In the Bazel build system, you would mark the test data blob as testonly=1. Then the build system guarantees that the blob can only be used in tests. This incident shows that killi…
