Every week we get a new AI that according to the AI-goodness-benchmarks is 20% better than the old AI, yet the utility of these latest SOTA models is only marginally higher than the first ChatGPT version released to the public a few years b

This would be acceptable if it meant adding one more shader, but with "modern" graphics APIs forcing us to sometimes have thousands of permutations for the same shader, every variant you add multiplies that count by 2x. We also do

A scary amount of critical FOSS projects are just some guy's hobby, and a hobbyist will often work on problems they find interesting, regardless of whether or not they're important for the "community". If you're com

Unfortunately our CEO at a 5000 person company that heavily uses Slack, still hasn't activated their Slack account, so I don't have much to finetune the bot on.

It's not the only technical control they have - every single datapoint an app can gather is ultimately provided from the OS. They could let you disable access to metrics that have proven to be useful for fingerprinting. They could also

Alright, just give me 5 minutes to quickly inspect the likely over 100,000,000 lines of code that either go directly into a ROM or are part of the build tooling, and reverse engineer however many binary blobs are involved in the process. Th

Fair point, but I highly doubt that this is how it's used most of the time. And taking 20 screenshots and compositing them in mspaint can be a meditative experience.

If that's what the license says, fair enough, but that's not how I parsed it. This is not a software-specific license so it's not as clear as say the GPL, where there's very explicit language for source code, object code

How exactly do you use what looks like work-planning software non-commerically? As for the license, it's their code and they can release it under whatever license they want, but they obviously shouldn't call it open source. Usuall

Reasoning about the lifetimes of objects in an arena is as simple as it gets - there's only one lifetime, and pointers between everything allocated on the arena are perfectly safe. The complexity of figuring out what's going on, w

You should never write code that's impossible to understand without fancy IDE features. If you're writing such code, the best thing you can do for yourself long term is switch to a text editor without LSP (read Notepad) right now,

We've forgotten how to do it - the idea of dragging a button offends our modern sensibilities. You can't just drag a button, what about the layout?! What about responsive design, how will it look on a 300x200 screen and a 8k one?

You can use modern MSVC or Clang with an old C runtime/Windows SDK. It's a pain in the ass since new compilers are way stricter with what they compile, so you get a bunch of warnings, but it will work.

It doesn't matter how many layers of Python you use to obfuscate what a LLM actually is, as long as the prompt and the data you're operating on are part of the same token stream, prompt injection will exist in one form or another.

My biggest problem with node-based programming interfaces is the absurd number of nodes required for even fairly simple expressions, e.g `b*b-4*a*c` is 9 characters in most textual languages, but it would require 9 nodes in most visual scri

While I wholeheartedly agree with the premise, the article doesn't really say anything other than "TCP good, your abstraction bad, don't use abstraction".

Doing frees/moves/copies on the second stack makes it harder to track the lifetime of allocations, and restricts what you can use it for - to free a block on the stack you necessarily have to free everything after it. Most program

You don't need explicit language support to do this -- it's a fairly common practice in videogame development, but we usually usually call it an arena/scratch buffer. Ryan Fleury has a wonderful article where goes at length a

This really doesn't add up to me. I don't have the numbers, but I would assume that: 1. A very small percentage of website visitors will end up paying for a subscription. 2. They make way less than $5 per user per month from ads.
