jwitthuhn··on Is AI Profitable Yet?
For immediate revenue yes, but if you want advertisers to keep coming back you need to give them a good conversion rate.
jwitthuhn··on Colorado Amended SB051 (Age Verification Bill) to Exclude Open Source Projects
It is very fortunate for us that the authors were kind enough to demonstrate this has nothing to do with safety by adding this exemption.
jwitthuhn··on Can someone please explain whether Cloudflare blackmailed Canonical?
"Renting attack capacity from [cloudflare]" is inaccurate as I understand things. That group hosts their site behind cloudflare but I have not seen anyone claim that cloudflare's infra is used for the attacks.

This whole article seems conflate hosting an informational site run by the attackers and hosting the attack itself.

jwitthuhn··on Metal Gear Solid 2's source code has been leaked on 4chan
I need scissors, 61!
jwitthuhn··on China blocks Meta's acquisition of AI startup Manus
Could you cite the specific law that makes it illegal for someone to export their thoughts?
jwitthuhn··on I cancelled Claude: Token issues, declining quality, and poor support
The checkboxes inform the model as well as the user, and you can observe this yourself. For example in a C++ project with MyClass defined in MyClass.cpp/h:

I ask the model to rename MyClass to MyNewClass. It will generate a checklist like:

- Rename references in all source files

- Rename source/header files

- Update build files to point at new source files

Then it will do those things in that order.

Now you can re-run it but inject the start of the model's response with the order changed in that list. It will follow the new order. The list plainly provides real information that influences future predictions and isn't just a facade for the user.

jwitthuhn··on Kernel code removals driven by LLM-created security reports
If the LLMs run by these people are turning up real bugs then their confidence in touching kernel code seems pretty earned, imo.
jwitthuhn··on Qwen3.6-Max-Preview: Smarter, Sharper, Still Evolving
I've been using qwen-code (the software, not to be confused with Qwen Code the service or Qwen Coder the model) which is a fork of gemini-cli and the tool use with Qwen models at least has been great.
jwitthuhn··on Game devs explain the tricks involved with letting you pause a game
My favorite as a kid was also in a Zelda game.

In the original (and maybe also DX) release of Link's Awakening, the game uses a top-down view with the world split up into tiles. Walking of the left side of a screen makes you end up on the right side of the next screen over.

What you could do is pause at the right frame on the screen transition, and you would end up on the new screen but link's position would not change. So you walk off the left side of a screen and end up on the left side of the new screen. Lots of fun to be had with skipping important stuff with that.

jwitthuhn··on Qwen3.6-35B-A3B: Agentic coding power, now open to all
128GB on a mac with unified memory. The model itself takes something like 110 of that and then I have ~16 left over to hold a reasonably sized context and 2 for the OS.

I do have a dedicated machine for it though because I can't run an IDE at the same time as that model.

jwitthuhn··on Qwen3.6-35B-A3B: Agentic coding power, now open to all
I've been largely using Qwen3.5-122b at 6 bit quant locally for some c++/go/python dev lately because it is quite capable as long as I can give it pretty specific asks within the codebase and it will produce code that needs minimal massaging to fit into the project.

I do have a $20 claude sub I can fall back to for anything qwen struggles with, but with 3.5 I have been very pleased with the results.

jwitthuhn··on Anthropic downgraded cache TTL on March 6th
It only potentially saves money for people on API pricing, it exhausts tokens faster with no benefit for users on the Claude Code subscription. Those users had their cache TTL reduced from 1 hour to 5 minutes and are saving no money because they were not paying based on the cache time in the first place.
jwitthuhn··on An update on Steam / GOG changes for OpenTTD
So they were not "pressured" but Atari contacted them and they proceeded to make this decision based because they "needed to balance Atari’s commercial interests".

That sound indistinguishable from being pressured.

jwitthuhn··on Illinois Introducing Operating System Account Age Bill
Why should an OS demand personal information from its users? It creates an unnecessary risk that the information will be leaked.
jwitthuhn··on California's new bill requires DOJ-approved 3D printers that report themselves
In the US there is a certain class of politician that considers poor people being able to exercise their rights a problem that needs to be solved.
jwitthuhn··on Janet Jackson had the power to crash laptop computers (2022)
The important distinction here is that CD-ROMs can store data indefinitely, but CD-Rs and CD-RWs can not.
jwitthuhn··on Quake's Player Speed (2017)
PVS by my understanding will only ever over-count visible polys.

It is essentially a set of all polygons that are visible from any point inside a fixed volume, but the camera only exists at a single point inside that volume so there will probably be some polys that the camera has no LOS (though I suspect these would still be 'rendered') to and a bunch that are out of the view frustum which will not be rendered.

edit: To observe this you can also load any HL1 engine game, run `r_speeds 1` in the console, then it will show you how many world polys are currently being drawn in the corner of your screen, which is probably the count referenced by John Romero here.

jwitthuhn··on Lua 5.5
The most recent integration I've seen is is OpenMW, which is an open source re-implementation of the Morrowind game engine. Basically it is built on the assumption that people are going to make mods that do a ridiculous amount of number-crunching in lua so any small improvement to performance is welcome.
jwitthuhn··on GLM-4.7: Advancing the Coding Capability
At 4 bits that model won't fit into 128GB so you're spilling over into swap which kills performance. I've gotten great results out of glm-4.5-air which is 4.5 distilled down to 110B params which can fit nicely at 8 bits or maybe 6 if you want a little more ram left over.
jwitthuhn··on The Illustrated Transformer
If you have 20 hours to spare I highly recommend this youtube playlist from Andrej Karpathy https://www.youtube.com/watch?v=VMj-3S1tku0&list=PLAqhIrjkxb...

It starts with the fundamentals of how backpropagation works then advances to building a few simple models and ends with building a GPT-2 clone. It won't taech you everything about AI models but it gives you a solid foundation for branching out.

jwitthuhn··on Valve reveals it’s the architect behind a push to bring Windows games to Arm
Rosetta 2 is going to be EOL'd within the next few years. A more permanent solution would certainly be welcome.
jwitthuhn··on Windows 11 adds AI agent that runs in background with access to personal folders
You are describing Windows 11 LTSC which is a product that exists because Microsoft knows people want to turn this crap off.

It is of course only available in volume licensing to keep it away from normal users. Only businesses get to control their computers.

jwitthuhn··on Windows 11 adds AI agent that runs in background with access to personal folders
Yes the security of every Windows computer was much better then, any software that automatically updates itself without user consent is obviously a massive security risk because the user is no longer in control of what software they run.
jwitthuhn··on Android developer verification: Early access starts
I would think it is pretty silly if I needed some sort of verification to drive people I personally know around because other people were getting their car hijacked after choosing to pick up strangers they found on the highway.
jwitthuhn··on Win11Debloat – declutter and improve your Windows experience
I see them going for $150-300 on ebay, just don't ask where they came from.
jwitthuhn··on Google pulls AI model after senator says it fabricated assault allegation
It is wrong to release something unreliable even while acknowledging it is unreliable? The product performs as advertised. If people want accurate information an LLM is the wrong tool for the job.

From the Gemma 3 readme on huggingface: "Models generate responses based on information they learned from their training datasets, but they are not knowledge bases. They may generate incorrect or outdated factual statements."

jwitthuhn··on Affinity Studio now free
So you can only use it if Canva has your email and they can send you exciting new offers.
jwitthuhn··on What happened to Apple's legendary attention to detail?
Worst part about this is that these days the error message simply lies to the user. "Whatever.App is damaged and can't be opened. You should move it to the trash."

If you remove the 'quarantine' attribute that gets added to downloaded files it runs great.

jwitthuhn··on NanoChat – The best ChatGPT that $100 can buy
Somewhat related: I wrote up a MTG card generator based on nanoGPT a while ago that I think produces pretty good results for being 1m parameters.

The real neat thing about this is that WotC makes a few thousand new cards each year, so my training data set just grows over time and the model gets better with no effort spent on my part.

jwitthuhn··on Microsoft only lets you opt out of AI photo scanning 3x a year
If they are worried about the cost of initial ingestion then a gate on enabling would make a whole lot more sense than a gate on disabling.
