Gonna be honest here, I've worked on this for so long, so many iterations, lots of versions for each 3D part, software and all, at this point I just wanted to publish everything I had and do it fast. And you are totally right, publishing without parametric source files was a mistake, I'll upload everything I have shortly, prices included. Note: mice require smaller setups and that just leads to the redesign of most parts - smaller ball, ball driver, lever with weaker springs... training cats prompts for a larger ball, same issue. VR setups for cats though would be super cool!

On this setup my rats were only habituated, they did not end up playing Doom. Even habituation seamed super slow, they were a year old when I started it. On the previous setup though, when they learnt to run on the ball and how that influences their reward, they got hooked. I believe they enjoy not just the reward, they get a sense of how their actions influence the game and they like that. They would run on the ball so much at some point they wouldn't even bother drinking all the juice and it was just dripping on the setup.

No idea what they would best like to play. It needs to be a first person game though, that's what they are able to understand how to handle, it's more natural to them.

Thank you for taking the time to give feedback! I also hope pet VRs become a thing and people can connect with their pets virtually too!

We still have complete control over the code, because after the AI generates it, it's right there to tweak as we want!

But the point is, there were no assumptions or tooling or bad designs that had to be fought. Just an informal, high-level prompt that generated the exact code I wanted in a fraction of the time. At least to me that was pretty surprising -- even if it'd become routine for a while by then -- because I'd expect that level of wavelength-match between colleagues who had been working on the same team for a while.

It makes a big difference for legibility which font you pick. But I see what you mean in that, if the font is "just fine" (not trying to be fancy or, say, in futuristic style for a game or something), then why bother making yet another "just fine" font as Google has done here? There's already so many sans-serif fonts that no person could tell apart if they don't see them directly side-by-side and are asked to spot the difference. For this reason, I also wonder why this release matters at all

I have been using Claude Code extensively on a side project (a hard sci-fi orbital tactics sandbox and battlefield simulator written in Rust with Bevy).

I recently attempted to create a procedural starfield background with multi-layer parallax, wired into the game.

I thought it would take an afternoon, and two weeks and three full rewrites later, I ended up with a list I’m calling: The 7 habits of highly ineffective agents

1. Planning Theatre – Write dense and systematically wrong plans. Long, confident plans that look impressive, get “approved”, and are fundamentally wrong in ways you can’t see without strong domain knowledge. 2. Confidently Incorrect Architecture – Design the wrong thing in incredible detail. Elaborate designs that can never solve the actual problem (e.g. starfield parallax without real layers / camera–world modelling), but look beautifully structured on paper. 3. Context Resistance – The context is futile. You will be hallucinated. Ask for Bevy 0.17 patterns, get Bevy 0.15. Agents “agree” with the updated context and then quietly fall back to older habits and half-remembered APIs. 4. Imaginary Implementation – Works on my hallucination. Code for an engine that doesn’t exist: non-existent APIs, obsolete shader interfaces, plausible-sounding data flows that won’t compile anywhere outside the model’s head. 5. Context Evasion – Treat hard constraints and instructions as optional vibes. The project had explicit, non-optional instructions (skills to call, architecture rules, testing strategy, etc.). The agent read them, acknowledged them… and behaved as if they were suggestions. 6. Applied Rationalization – Explanation over implementation. When something fails, the agent doesn’t just explain it – it bakes the explanation into the codebase: ignoring tests, downgrading issues to “non-blocking”, justifying precision loss, and moving on. 7. Weaponised Context – The context will continue until the code improves. By the end, the feature had volumes of surrounding context: plans, handoffs, bug explanations, revisions. Each failure generated more docs for the next agent to inherit and ignore.

I’m curious how this matches other people’s experience with Claude / Claude Code (or your own agent stacks): - Which of these habits have you seen the most in your own workflows? - What have you done that actually reduced these failure modes (gating, skills, checklists, stricter prompts, something else)? - Are there other “habits of highly ineffective agents” you’d add to this list?

Would love to hear horror stories and what’s working for you.

The “20th century atrocity denial” comparison is disgusting and transparent. Holocaust denial is rejected because it contradicts a mountain of primary evidence. You are doing the opposite. You are trying to manufacture certainty where the documentation is missing, then calling anyone who asks for records a “denialist.”

On the Truman claim, you keep saying “adequate evidence” while producing none. The best you have is a biography by Truman’s daughter decades later that does not cite sources and newspaper blurbs repeating those claims. That is not “well documented.” That is the stuff of conspiracy theory.

Here is what you still have not provided: a contemporaneous Secret Service report, a White House mail log entry, an FBI memo, a case number, a preserved device, photographs, lab notes, arrests, indictments, or any archival file tying an actual bomb to Lehi. In fact, a FOIA request to the Secret Service for records of this alleged incident came back “no responsive documents,” and the Truman Library reports it has nothing and explicitly notes that Margaret Truman’s biographies rarely cite sources.

So no, you do not get to say “adequate evidence” and then hide behind moral outrage.

Your next move is equally sloppy. “They operated with the permission of the government.” In 1947 there was no Israeli government. When the state did exist, it disbanded Lehi, arrested members, and fought Irgun in the Altalena affair.

If you have a primary document tying a Truman mail bomb to Lehi, post it. If you do not, drop the Holocaust baiting and admit you are repeating an allegation you cannot substantiate.

And your finale, that Irgun and Lehi represent “the nature and spirit of the Israeli people today,” is just collectivist bigotry. “Terror cells are usually small,” you say, and then you claim two fringe militias somehow define millions of Israelis. That is not analysis. It is an ethnic smear.

GPUs: 4x NVIDIA RTX 6000 Blackwell (96GB VRAM each) • Cost: 4 × $9,000 = $36,000

• CPU: AMD Ryzen Threadripper PRO 7995WX (96-Core) • Cost: $10,000

• Motherboard: WRX90 Chipset (supports 7x PCIe Gen5 slots) • Cost: $1,200

Yes, in fact the name Lite³ was chosen because it is lighter than SQLite.

I thought about implementing something like jq or JSON query, and this is very possible. It is like sending a mini-database that can be queried at speeds thousands of times faster than any JSON library is able to parse.

One interesting effect of being a zero-copy format is that the 'parsing speed' can exceed the memory bandwidth of the CPU, since to fulfill a query you do not actually need to parse the entire dataset. You only walk the branches of the tree that are actually required.

I've talked to some other people that have also shown interest in this idea. There doesn't really seem to exist a good schemaless single-file format that supports advanced queries. There is only SQLite and maybe HDF5.

It's sadly all too common. I worked at a Fortune50 retailer with a massive IT org. Was on a call one day with one of our most Senior Ent Arch who was excitedly telling me about how "these Java scripts" were the hot new thing and we were building "modern web 3.0 pages" with them. He did not understand the difference between Java and JavaScript or a blockchain branding exercise and SPAs.

> The main challenge is latency since you have to do much more frequent communication.

Earlier this year I experimented with building a cluster to do tensor parallelism across large cache CPUs (AMD EPYC 7773X have 768mb of L3). My thought was to keep an entire model in SRAM and take advantage of the crazy memory bandwidth between CPU cores and their cache, and use Infiniband between nodes for the scatter/gather operations.

Turns out the sum of intra-core latency and PCIe latency absolutely dominate. The Infiniband fabric is damn fast once you get data to it, but getting it there quickly is a struggle. CXL would help but I didn't have the budget for newer hardware. Perhaps modern Apple hardware is better for this than x86 stuff.

Which is odd, because to us Brits and to Europeans, essentially all American mass-produced chocolate tastes and often smells like vomit.

ETA: I am making no claims that Cadbury Dairy Milk is world-class chocolate, by any means (though I dislike Belgian chocolate even more). It's quite cheap and slutty chocolate, which is a small part of why we like it. But internationally, you guys have the worst chocolate, hands down. Nobody thinks it's better but you guys.

ETA2: I should add that I think one of the post-US-acquisition Dairy Milk recipes, the Marvellous Creations Jelly Popping Candy bar, is the best thing they've made in a generation, and I include in that the gorgeous Australian-recipe Caramilk that they tried to make a thing here and largely failed at.

I'm not interested in litigating this claim because it has nothing to do with what I'm talking about. If it helps, you can be as angry at Israel as you'd like without getting much flak from me (I'm angry too), just as long as we don't get to the "enemy-of-my-enemy" stuff that legitimizes Hezbollah.

I don't think "terrorist" is a useful label for either side. It wasn't "terrorism" when Hezbollah besieged Madaya; they did that as a military force.

I am so curious to learn more about this. Are there any extensive write ups of the mechanics of identification, price points, whatever? Or is it all insider baseball because it is distasteful?

Many tens to hundreds of dollars for that single datapoint is incredible. I have naively assumed we were just packaged up in aggregate and never thought more deeply than that.

What are the most valuable data? Pregnant? Wedding? Divorce? Illness? Home purchase?

The problem is you still think that the perfect prompt or AGENTS.md or whatever is going to get you a one-shotted (or close) feature in return. There isn't (yet) a model or orchestration framework that is going to take a large feature from start to finish for you.

The reality is that LLMs/agents are just a new way to write code. You still need to understand, more-or-less, how this feature is going to actually work, and how it needs to be implemented, from start to finish.

The difference is that you don't write the code, you tell the LLM to write the code. Once you've figured out the right "chunk size" an LLM can handle it's faster than doing it yourself.

I've found it's actually a little _harder_ in green field projects because the LLM doesn't have guard rails and examples and existing patterns to follow.

I think the Administration is likely to get its toys taken away soon.

the Major Questions Doctrine, the end of Chevron deference, the mandate for Article III courts from Jarkesy, have been building towards this for a while. the capstone in this program of weakening the administrative state, overturning Humphrey's Executor when Trump v. Slaughter is decided, will likely revive the Intelligible Principle Doctrine, as Justice Gorsuch has hinted. the same trend is apparent in the IEEPA tariffs case, where non-delegation got a lot of airtime.

EOs lose a lot of their punch when the Executive's delegated rulemaking and adjudication powers are returned back to their rightful owners in the other two branches.

from a purely technical point of view i do wish HDMI 2.1 was able to gain traction. On a couple of things I own that do actually use it, its an actual noticeable improvement and I feel does a better job than DisplayPort.

Granted, I suspect quite strongly the next wave of consolidation is going to continue the trend of being around USB-C, since the spec should have the bandwidth to handle any video / audio protocols for quite some time. Matter of time until that happens IMO.

It also lets you have a single cord that could theoretically be your power cord and your A/V cord.

There's no particular reason an Auth system must be designed like counterexample #2. There's many ways to design that system and avoid cycles. You can leverage caching of role information - propagated via messages/bus, JWT's with roles baked-in and IDP's you trust, etc. Hitting an Auth service for every request is chaotic and likely a source of issue.

I can see how you'd do an especially I I. You just need to include the serifs, which I always do in handwriting anyway.

But how do you emphasize a lowercase 'l'? The only method I know is to make it cursive, which looks terrible.

(I don't really need to distinguish l from I, because I put serifs on I. But I do sometimes need to distinguish it from 1; in natural writing, 1 and l are identical.)

For things pushed to github, github has quite sophisticated secret scanning. They have a huge list of providers where they will automatically verify if a potential key is real and revoke it automatically [2], and a smaller list of generic patters they try to match if you enable the matching of "non-provider patterns".

This seems to be a case of someone accidentally publishing their github token somewhere else. I'm not sure how github would cheaply and easily prevent that. Though there are third party tools that scan your web presence for secrets, including trying wordlists of common files or directories

> I have also seen this used in other formats quite successfully - Fandom/Wikia (used to?) use a MySQL database for each sub-site.

Stack Overflow used it as well, with a database per site (DBA.StackExchange.com, ServerFault, SuperUser, Ask Ubuntu, etc.)

I have a bunch of clients using it. Another drawback with this design is high availability and disaster recovery can become more complex if you have to account for an ever-growing number of databases.

> we need a hyper-productive world where someone working a few hours a year generates enough wealth to secure a comfortable lifestyle up there with the best of them.

This is naive, productivity increases had decoupled from compensation a long time ago. See https://www.epi.org/productivity-pay-gap/ for example. AI certainly can create wealth, and in fact already did (hey NVDA), but somehow that did not trickle down. I think more likely than not, AI will further stratify our society.

> Words virtually always have redundancy (or context in the sentence) and it's fine in 98% of cases, but too often someone sends a token, password, name, or other string where you need to copy it out to another application to see it and just... why?

I think the right answer here is to avoid including 1/I/l/O/0 in your tokens. For example, I'm pretty sure that Nintendo gift card codes can't contain those characters?

This is a tribute system, way past lobbying. Lobbying is cheap, Senators can be bought off for 5-figure sums. CEOs pay lobbyists so they don't have to meet with them personally. What's happening now involves CEOs appearing at political events and lobbying the president personally, to the tune of millions of dollars in declared "donations" for "ballroom construction", in exchange for security guarantees for their business empires.

Thanks, that’s good advice

Ideally all my home devices would controlled and managed by the same underlying OS and tooling

I have to stop being such a prude, it just frustrates me that after so many years I can’t buy a cheap Linux tablet

I used to frequent a wonderful Ace Hardware with some regularity.

The old lady that always seemed to be behind the register eventually started greeting me by name when I walked in. (I don't recall ever giving her my name; maybe she remembered seeing on a credit card or something.)

After the pleasantries (which didn't seem fake at all), one of the greybeards present would appoint themselves as my personal shopper. I'd go down my list of demands that was only vaguely sorted by department: "One M8x1.25x80mm all-thread stainless Philips screw, a 16x20 furnace filter, a box of #8x3/4 sheet metal screws, and uh... what do you have for can openers?"

And then we'd make a lap or two of the store to get these things, and I'd pay and GTFO.

It was great.

Right, my comment was mostly about decoding speed. For prefill you can get a speed up but there you are less latency bound.

In our benchmarks with MLX / mlx-lm it's as much as 3.5x for token generation (decoding) at batch size 1 over 4 machines. In that case you are memory bandwidth bound so sharding the model and KV cache 4-ways means each machine only needs to access 1/4th as much memory.

Crawlers will find everything on the internet eventually regardless of subdomain (e.g. from crt.sh logs, or Google finds them from 8.8.8.8 queries).

REQUIRE_SIGNIN_VIEW=true means signin is required for all pages - that's great and definitely stops AI bots. The signin page is very cheap for Gitea to render. However, it is a barrier for the regular human visitors to your site.

'expensive' is a middle-ground that lets normal visitors browse and explore repos, view README, and download release binaries. Signin is only required for "expensive" pageloads, such as viewing file content at specific commits git history.

Every time somebody wants to do something in Linux and they mention Objects, I turn around and go the other way.

These people still do not understand why that userspace became so powerful and so useful.

I also think that's the "solution", which is to craft a new optional userspace experience that leaves traditional unix strings and pipes alone. It's not for me, but I'm sure many would like it. I mean, look at PowerShell on Linux :/

One thing I noticed is that you tested it with very short prompts; Z-Image Turbo really likes long prompts, and recommends using an LLM as a prompt enhancer, even providing a prompt template.

China encourages exports and has no recent history of confiscating property owned by foreigners. Combined with cheap labor this makes it a great place to set up sweat shops. If you are selling a good that can be made in a low labor area but you use high cost labor you will be outcompeted and the market wont buy your expensive products so over time all the successful firms make their low skill products in sweatshop zones
