jwitthuhn··on Rio de Janeiro's "homegrown" LLM appears to be a merge of an existing model
They did upload the wrong model but as of the time of writing they have not fixed it. Right now, 12 hours after they took the old one down, there is simply no model present in their huggingface repo.
jwitthuhn··on Statement on US government directive to suspend access to Fable 5 and Mythos 5
Fortunately for us all Dario literally asked for this sort of restriction on model usage so we can be certain Anthropic are not victims here.
jwitthuhn··on Web Browsers on Video Game Consoles
Same for switch 1/2. it even has a browser built-in so you can log in to wifi captive portals but you can't access it through any normal means.
jwitthuhn··on Apple decided not to roll out Siri in EU after denied request for exemption
It is not a backdoor if I authorize some other app to use that data, it is a front door.

Apple thinks users should not be able to make the decision about who can access their data. It is not more complicated that that.

jwitthuhn··on US House lawmakers release draft bill to prohibit state AI rules
Thanks for the correction, I had misunderstood that and thought it applied more broadly but it is indeed just "source code".

Given that, I'm glad to see something that protects software more broadly.

jwitthuhn··on US House lawmakers release draft bill to prohibit state AI rules
Good, Bernstein v. United States already established that software is speech. Limitations on what software one is allowed to produce are very blatant prior restraint.
jwitthuhn··on MAI-Code-1-Flash
And occasionally un-releasing them like with WizardLM.
jwitthuhn··on GitHub bans security researcher who posted zero-day Windows exploits
Forks are still alive on github, so it seems unlikely microsoft did this to suppress the code. Unless they are wildly incompetent, which I don't want to outright reject as a possibility.

Unfortunately I don't think there is any way to see a list of all the forks now that the main repo is dead, but you can search the phrase "A huge thanks to MORSE, MSTIC and Microsoft GHOST for making this public disclosure possible" to find more copies.

jwitthuhn··on Claude Opus 4.8
Yeah I've also found that models are good enough that the extra spend on premium models isn't always worth it, particularly for my small personal toy projects.

A $20 claude sub goes a long way when you plan with Opus and execute with Sonnet.

jwitthuhn··on California moves to exempt Linux from its age-verification law after backlash
"One can point out that such electoral pitches are dishonest bullshit until one is blue in the face"

This is what I intend to do. To just let lawmakers get away with passing bullshit because "of course they will" is a defeatist attitude that I don't advocate.

That is why it is so important to be loud about this incredibly obvious disingenuous behavior. Make sure everyone knows the people advocating this do not care one bit about children's safety.

jwitthuhn··on California moves to exempt Linux from its age-verification law after backlash
It is an admission from the writers that this law is unrelated to safety and people should very loudly and frequently point that out.

If OSes that don't verify the age of their users are a genuinely unsafe for children, why should they be allowed just because they are open source? That doesn't seem to mitigate dangers associated with age in any away I can identify.

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.
