feedback VS Git

I stated using gofakeit's "hackerphrase" for all commit messages.

https://github.com/andrewarrow/feedback/commits/main/

hp | git commit -a -F -

hp is a golang binary that just spits out a hacker phrase. I have this aliased with the letter q for "quick" so I'm always checking in stuff with q return push done.

"zip_locations_zip_index" UNIQUE, btree (zip)

The following takes hours and hours to run:

https://github.com/andrewarrow/feedback/blob/main/location/zip.go

But you end up with a nice way to get an approximate postgis geometry for any zip code in the USA. (For free.) Anyone know of a faster way?

My favorite part of this code is buffer := make([]byte, 1). By making the buffer just a single byte, I can look for "\n" so much easier than if I was reading in 1024 bytes or 2,048 bytes etc and then I have to find that \n in the middle.

I love this list. One thing I'll add is I like to avoid using S3 or google's cloud storage AT ALL until I have > 30 GB. i.e. with google free tier of their compute engine you get a 30GB hard drive, 1GB ram, and two AMD EPYC 7B12 2250 MHz processors. So I make a fake bucket system using those free 30GB:

All I code I write is in bucket form, ready to flip a switch and use real buckets but 100% free up to that hard drive limit.

I just used a mutex here:

https://github.com/andrewarrow/feedback/blob/master/stats/me...

Multiple go routines will call this method at same time but:

https://github.com/andrewarrow/feedback/blob/master/router/p...

Where I call it I start a new go routine so nothing is ever waiting on that mutex right?

So this question https://news.ycombinator.com/item?id=35198563 prompted me to revisit the framework demo'ed here https://news.ycombinator.com/item?id=35033368

Just like reddit lets you go to what might be a 404 page /r/anything-you-want and you can then create that subreddit, I added this feature to remoterenters so you can make /rr/anything-you-want and be the mod of that sub.

To get the ball rolling with some content I made these two AI based subs:

https://remoterenters.com/rr/amazing-ai-understanding/

https://remoterenters.com/rr/writing-prompts/

And my friend "not_a_t1000" bot helped me add some interesting content. My favorite one in "amazing-ai-understanding" is about the Steering Wheel! How can it know this subtle meaning! So impressed!

Feel free to create your own new subs or add to these. Everything is open source. You can follow along with the commits to the "go on rails" framework here:

https://github.com/andrewarrow/feedback/

and the sample app here:

https://github.com/andrewarrow/remoterenters/

if anyone wants to pay for the domain, I'll set up copies of this https://remoterenters.com/ for any topic you want. Trouble is hard to compete with:

https://www.reddit.com/r/worldnews

https://www.reddit.com/r/marketing

https://www.reddit.com/r/business

for traffic and users.

paste an example search with zero results in code. Like I did:

https://github.com/andrewarrow/feedback/search?q=view&type=c...

but

https://github.com/andrewarrow/feedback/search?q=views&type=...

does have results.

I'm not sure exactly what features to add next to this site https://remoterenters.com/ but the idea is to help people find a building where their rent is actually a good deal. Because yes, many people will never get a mortgage and buy a condo or house. And a16z has a plan to give renters equity in their building + make the experience of living there 10x better.

Look at any PR/patch series that got merged into the Git project. https://github.com/git/git/

Any random one. Because those that did not meet the minimum criteria for a well-crafted history would not have passed review.

Boy, I can't find this either (but also, the kernel mailing list is _really_ difficult to search). I really remember Linus saying something like "it's not a real SCM, but maybe someone could build one on top of it someday" or something like that, but I cannot figure out how to find that.

You _can_ see, though, that in his first README, he refers to what he's building as not a "real SCM":

https://github.com/git/git/commit/e83c5163316f89bfbde7d9ab23...

Here is the direct link, as HN somehow removes the query string: https://github.com/git/git/commits?author=peff&since=2023-10...

I understand all that.

I'm saying, if you write a survey and one of the possible answers is "diff", but you don't clearly define what you mean by "diff", then don't be surprised if respondents use any reasonable definition that makes sense to them. Ask an ambiguous question, get a mishmash of answers.

The thing that Git uses for packfiles is called a "delta" by Git, but it's also reasonable to call it a "diff". After all, Git's delta algorithm is "greatly inspired by parts of LibXDiff from Davide Libenzi"[1]. Not LibXDelta but LibXDiff.

Yes, how Git stores blobs (using deltas) is orthogonal to how Git uses blobs. But while that orthogonality is useful for reasoning about Git, it's not wrong to think of a commit as the totality of what Git does, including that optimization. (Some people, when learning Git, stumble over the way it's described as storing full copies, think it's wasteful. For them to wrap their heads around Git, they have to understand that the optimization exists. Which makes sense because Git probably wouldn't be practical if it lacked that optimization.)

The reason I'm bringing all this up is, if you're trying to explain Git, which is what the original article is about, then it's very important to keep in mind that someone who is learning Git needs to know what you mean when you say "diff". Most people who already know Git would tend to gravitate toward the definition of "diff" that you're assuming (the thing that Git computes on the fly and never stores), but people who already know Git aren't the target audience when you're teaching Git.
