Would you mind sharing what AI note taking app do you use?

Interesting - would you mind sharing a link?

Cool, thanks for sharing. It's these kind of experiences that I was hoping to gather from making this post. Did you notice at the end that you did NOT end up choosing ARM? You ended up going with x86_64 because that's what made mo

Thanks, I didn't know about c6g, m6g, r6g. I've updated the post to remove this mention - I only counted a1 instances. That still leaves storage optimized and GPU optimized instances missing. I'm guessing storage should be ea

Awesome, thanks for testing this out! A 3x slowdown is not as bad as 6x, but it's still quite a bit. I also saw a slowdown of ~4x when I tried this experiment on a native Linux x86_64 running ARM - perhaps the Mac -> Linux virtualiz

Author here. > 1. If emulating aarch64 (arm64) on x86_64 is 6x slower (on your system, btw, it's not an universal constant), it doesn't mean emulating x86_64 on aarch64 will be 6x slower. It'd probably be worse, or at leas

Author here. I'm glad somebody said something! Yes the gzip perf test is pretty silly, but illustrates a significant difference. /dev/urandom throughput on this setup was about 100 MB / s so it wasn't a bottleneck f

Author here. That's a major point of the article - "are we screwed?" I'm not an expert on virtualization but I wanted to see some discussion on this topic, because it feels like we might be screwed and nobody is talking

The speaker mentions that Redis, MongoDB and background jobs were replaced by Erlang. What does he mean by that exactly? Erlang provides some persistent state storage? Or is he just saying he used Erlang database drivers to access Redis &#x

It sounds like you're skeptical about companies that affect people's habits. So avoid these terms: - finance - advertising - entertainment I'd focus on companies that sell to other businesses. Changing the habits of businesse

This is a nice article, with a comprehensive if long history of npm and node. I agree with the author that there will one day be a reckoning with npm, inc - they'll shut down abruptly, or do something people are really unhappy with. Ho

In a lot of organizations there are "bug teams", whose job is to detect bugs, fix some, and make fixing them easier. However, you probably don't call them "the bug team". Examples: Site reliability. If devs ship a b

I think the right approach here is to figure out how to use git in the company IDE. Then, have a presentation / workshop about how to use git in the IDE. Personally I prefer the command line, but I imagine your coworkers will be a lot

As a former Cisco employee, I can tell you why companies never want to open source their security-sensitive products: Pros of open sourcing a product: - fewer total number of vulnerabilities Cons of open sourcing a product: - more publicly-

The article makes it sound like you have to choose between two options: 1. users see example.com in the address bar 2. hosting on www.example.com However you can get the best of both worlds. If you go to amazon.com, you will see amazon.com

I have a similar setup to GP: Emacs + one file + an "new-day" command. Everything goes in one big "scratch.txt" file, with headers like: ###### Saturday, May 20 2017 ...at the start of each day. These are genera

Also not GP, but I also have notes per-day. If you organize by topic, you have to decide which topic to put information in. This means you have to pause and think for 10 seconds about your organization system before writing anything. 10 sec

Great, thanks for the reply and links. Sounds to me like the current state is "doable," but not "solid." I can convince myself to try it out, but not my whole company. But, maybe this will improve over time.

I am a systems programmer working at a company with a largely C++ codebase. We don't use Rust. It has nothing to do with the reasons mentioned in the article or this thread. Here are a list of requirements for us to use Rust: - Doe

My point wasn't optimization. Just that the author was making it more complicated than was needed. It's like discovering that "ls" is spawning 5 threads for internal communication.

by bmalehorn 10y ago
The code is more complicated than it needs to be. It spawns N threads, then each thread forkexecs child processes. These threads communicate through an atomic int. There is no need for threads. Just spawn background processes: echo 1
