Normal clones can reuse delta-compressed data the server stored on disk. Shallow clones impose a negative constraint: do not transfer data outside the requested commit depth. Pre-computed delta chains than contain unrequested data become un

I like ed but I prefer 'sam -d' (the terminal mode of Sam). It has a nice looping construct 'x' and you can open multiple files and do batch edits (with 'X'). There is a Go port of Sam, which is easy to install

I tried plan9port's mk for a moment out of curiosity. I quickly ran into an annoying usability problem: it compares file mtimes with second accuracy. https://github.com/9fans/plan9port/blob/cc4571fec67407

The article does not talk about security problems. It's about whether your daemon works correctly. 1. Depending on the environment, process supervision can break if there is an unexpected process sitting between the supervisor and the

I'm not sure. Intuitively I would think "phase angle" means "offset into the sine wave lookup table". If you step through the lookup table with constant size steps, you would get a sine wave. If the steps are not co

Only original DX7's, or also the DX7ii? Opening up the DX7ii (and other synths from the same time) is a pain compared to the nice hinge construction you get on the original DX7.

>not necessarily much safer than void* You can cast void* to anything you want. With interface{} you get a type check, either through an assertion or a panic. That is a big difference in safety.

I think "everything is a file" also means: everything is addressable by a file path. Per-process namespaces are part of what makes this possible. In a way it's similar to HTTP REST, which is also organized by file paths, exce

Ubuntu 18.04 (Linux 4.15) in xhyve works fine for me. I tried to get 20.04 set up a while ago but I gave up because its installer kept flaking out on me, something about the disk if I remember correctly.

I wonder how this compares to xhyve, which I use on Intel Mac. It's nice to see something like it for ARM. It appears xhyve is built on Hypervisor.framework while vftool is built on Virtualization.framework. Is that the main difference

I think the issue is about having to cross a module boundary, which is really about monorepo vs multirepo. You have much more freedom to make breaking changes when you don't need to cross a (repo/module) boundary. I think the Go m

Clang on my macOS doesn't like the fact that main() takes and returns long long. But it appears GCC on Debian 8 (random linux I have lying around) doesn't mind. I get it to compile on macOS if I remove the int define but then it s

I'm not sure but I suspect the algorithm contains optimizations that require direct access to the "limbs" of the big integers. Or perhaps it's about avoiding allocations?

The user experience of doing this is very bad. Every time I look into doing this I end up with blog posts that describe punching numbers into the GPG CLI, master keys, subkeys, PIN's. I don't want to be a GPG enthusiast, I just wa

I think vendoring is very useful and it would be a step back if it becomes harder. Caching proxies for zip downloads sounds nice, but it's more than just "a bit more infrastructure". I think it would be a huge burden to packa

Another nice example is changing the working directory for the new process. With fork+exec, you can do a chdir after fork but before exec. With posix_spawn you're stuck with the working directory of the parent.

I'm on the Gitaly team. As zegerjan wrote, Gitaly is a Go/Ruby hybrid. The main Go process doesn't use libgit2 (for now) because we didn't want to have to deal with cgo. We already know how to deal with C extensions in R

Cool! I used BSD ed (OS X) exclusively for a few months but I stopped because of a few things that were too clunky for me. Wrapping text: I used fmt all the time. But you can't pipe text straight through fmt, so I ended up doing this a

It's not just Arch. I used to think ed was everywhere, so when I had to write some scripts that would be awful with sed I used ed. And then it turned out that a lot of the platforms people run the scripts on, they had to install ed exp

Sure, it was my mistake on two counts (not keeping a root session AND blindly changing the config). That does not necessarily mean I am alone in making that mistake so I thought I would try to warn others.

Hmm I was wrong, the current version of the built-in Git daemon has an --access-hook option so no problem there. https://github.com/git/git/blob/56f37fda511e1615dc6df86c68f3... The question is then: how badly
