Thank you, though I am more afraid this will make my positive symptoms worse. I really have no negative symptoms of schizophrenia, which is why I am schizoaffective and not schizophrenic. Glycine seems to activate the glutamate receptors[1] and sarcosine is a by product of glycine and has also been shown to increase mania in patients[2].

What is interesting is that high levels of B6 seemed to help me in the past and it is a cofactor for SHMT1[1] which balances serine and glycine in the folate cycle.

There's no link to the paper, so I can only infer, but, if I understand correctly, this is a very simple idea: take a single Gaussian splat "tile" and find a cut when two copies are placed near each other and overlapping, using dynamic programming to vary the size of overlap and where the cut should be. Have a variety of cuts to break a uniform tiling (the Wang tiles part) and now you have different tiles with different nearest neighbor constraints that you can use to tile the plane.

Probably a lot of details to be worked out in how to stitch Gaussian splats together but I imagine it's pretty do-able.

I think one of the problems with Gaussian splatting is generating content. You can take a static picture of something but it's hard to know how to use it for interaction. This is a way to generate 3d textured sheets, like sunflower fields, walls, caves, etc.

In my opinion, great idea.

Owning your runtime is not about developer experience at the scale of Claude Code, it’s about your execution-surface area and the control you have over it.

Agentic systems are no longer just model-driven — they are increasingly runtime-driven through tools, sandboxes, and orchestration layers. When agents are writing code, executing tests, calling external tools, and validating outcomes, the reliability of the entire system becomes a function of the runtime and environment, not just the model.

Controlling the runtime gives Anthropic vertical control across:

- Packaging and distribution - Execution semantics - Performance characteristics - Security surface area - Operational stability

Of course, owning a JavaScript runtime does not magically make runtime deterministic. The dominant sources of variability still sit lower in the stack: OS behaviour, native dependencies, filesystem semantics, scheduling, hardware differences, and network effects. Runtime ownership is necessary, but not sufficient, for true runtime determinism.

What this does signal is a strategic shift in where value is being captured.

Model capability is no longer the only critical layer.

The execution plane is becoming just as strategic too, can see this in ChatGPT 5’s dynamic model routing capability as well as ecosystem wide Tool Calling and MCP adoption, which are all aimed at increasing LLM determinism through traditional software stacks.

Vertical integration here looks far less like a tooling move and far more like a control-plane strategy: consolidate the stack, reduce dependency entropy, and shrink the surface area where behaviour can diverge.

Intelligence may live in the model, but reliability, scalability, and trust are increasingly properties of the system that executes it.

> American pickups are very practical for what they are designed for. Your 4 cylinder hatchback is not going to pull a 20,000lb trailer up a steep grade or haul enough lumber to frame in a house, or a 7,000lb bed full of gravel.

An f150 can do none of these things.

> While there are very visible idiots in the USA that drive big trucks for aesthetic reasons

That is 95% of the market.

> there are also plenty of farmers, contractors, etc. that need them as a practical tool to haul heavy loads.

For the average contractor a panel van would be more capable and useful. You can put 3 metric tonnes in a man tge (and actually have the space for it) and tow a 3.5 tonnes trailer. And it’s available bare if you need an open bed, or a custom rear (e.g. for a lift).

I'm not an expert but I was just looking into this so I will leave this link here:

https://en.wikipedia.org/wiki/Euclidean_rhythm

If I understand it right, Toussaint's 2005 paper showed that many common rhythms across world music can be generated by distributing beats as evenly as possible. Some of the patterns in this newer research are Euclidean, but the broader finding is that people have a natural affinity for small-integer-ratio rhythms generally. So this is empirical evidence of why these mathematically simple patterns (including Euclidean rhythms) show up across world music.

I liked the idea behind this post, but really the author fairly widely missed the mark in my opinion.

The extent to which you can "fool the optimizer" is highly dependent on the language and the code you're talking about. Python is a great example of a language that is devilishly hard to optimize for precisely because of the language semantics. C and C++ are entirely different examples with entirely different optimization issues, usually which have to do with pointers and references and what the compiler is allowed to infer.

The point? Don't just assume your compiler will magically make all your performance issues go away and produce optimal code. Maybe it will, maybe it won't.

As always, the main performance lessons should always be "1) Don't prematurely optimize", and "2) If you see perf issues, run profilers to try to definitively nail where the perf issue is".

I'm a little older than you (mid fifties) and back in my day we couldn't have walkmans/headphones on inside the school. I walked so in the winter I would wear headphones instead of earmuffs/hats (had to rock that 80's hair) and got in trouble all the time. Like one step in the building and busted.

I think the biggest barrier to a phone ban being more widely adopted is parents. My wife works in the front office of a middle school and parents lose their minds if a kid gets their phone taken away. "But but but what if I NEED to get ahold of my kid during the day?". Umm... You ask the school to get your kid? I dunno seems pretty straightforward.

Then again I'm in an affluent area where moms against liberty (as I call them) are prevalent so maybe it's just the people here?

> "It's no surprise to see modern AAA games occupying hundreds of gigabytes of storage these days"

Is it not? I've genuinely never understood it!

I used to do a little bit of level building for IdTech3 games back in the day but it's been 20 years. I'm not totally ignorant of what's involved, just mostly ignorant. I really want to know though, what is all that data!? Textures?

In particular I find the massive disparity between decently similar games interesting. Indiana Jones and the Great Circle takes something like 130gb on my Xbox, whereas Robocop: Rogue City takes something like 8gb. They have similar visual fidelity, I would say Robocop might have a little bit of a lead, but Indiana Jones has fancier dynamic lighting.

At 130gb though, I almost could have streamed my entire playthrough of the game at 4k and came out on top.

The first 16:9 content I ever saw was the trailer to "Batman Forever" (with Val Kilmer) in 1995 when I was working at C-Cube Microsystems. The studios use to send them test content all the time for video compression testing. It was on D1 tape, and looked beautiful for SD resolution. The professional Sony CRT 4:3 monitors back then had a 16:9 button to letterbox the image.

According to this link [1] 200k would put someone above the 80th percentile and not far below the 95th percentile in terms of household income for the DC metro area, so I don't see how that could be considered "underpaid", especially when you consider the benefits.

It's not about not knowing about an optimization. The challenge is to know when to apply it, so that it does not cause regressions for cases that can't benefit from it. It may be less risky in specialized systems, like BI systems typically don't need to worry about regressing OLTP workloads. Postgres absolutely needs to be careful of that.

I believe that's one of the reasons why it took about ~8 years (the original patch was proposed in 2017).

They actually do, if you ask them better questions. "Inequality" is a boogeyman that has a lot of baggage attached to it by society but, if you were to ask people if it was a good thing for millions of people to be lifted out of poverty if the cost was that on person was obscenely wealthy, most people would side on the side of inequality.

"Inequality" is just an academic word for "Keeping up with the Jones'". Each generation has more material good, both necessities and otherwise, than previous generations. It's only through comparison that people are made to feel poor. Rather than look at trends of poverty and flourishing, people are made to feel cheated by not getting a slice of someone else's pie.

Ehh I am the nerd and I’ll start the convo. I actually think this gets me in trouble. People judge the book by the cover.

This question ignores that this problem exists with people as a whole.

People after all are full of emotions and are ego driven. I think that most of people’s negative responses intimately boil down to fear…

This new hire makes me look bad I am worried that so and so is better than me What if their implementation is better and their company does better than mine

Instead of being happy and comfortable with the uncomfortable people react poorly

If your language has monomorphization† (as C++ and Rust do) then it's really common to have this commonality in the emitted code and I believe it is common for compilers to detect and condense the resulting identical machine code. If the foo<T> function for an integer checks if it's equal to four, it well be that on your target hardware that's the same exact machine code whether the integer types T are 1 byte, 2 bytes or 4 bytes and whether they're signed or unsigned, so we should only emit one such implementation of foo, not six for u8, i8, u16, i16, u32 and i32.

† Monomorphization takes Parametrically Polymorphic functions, ie functions which are strongly typed but those types are parameters at compile time, and it emits distinct machine code for each needed variation of the function, so e.g. add(a, b) maybe gets compiled to produce add_integer(a, b) and add_float(a, b) and add_matrix(a, b) even though we only wrote one function, and then code which calls add(a, b) with matrices, is at compile time emitted as calling add_matrix(a, b), because the compiler knew it needs that version. In C++ the number of parameters is also potentially allowed to vary between callers so add_matrix(a, b, c, d) might exist too, this feature is not yet available in Rust.

"Our baseline finding is that both congressional leaders in their pre-leadership years and their matched 'regular' members underperform the benchmark by similar magnitudes"

"Earlier studies of lawmakers’ trading by Ziobrowski et al. (2004 and 2011), found their portfolios to outperform the market. However, this conclusion is reversed in later studies. In particular, Eggers and Hainmueller (2013) and Belmont et al. (2022) document the opposite—members of Congress underperform the market during 2004-2008 and 2012-2020, respectively."

I guess the title of "Congress members suck at trading stocks, but suck less once in leadership positions" was already taken

One of the great powers of federalism is not having to duplicate efforts for every state. It also reduces cost by allowing 'one-size-fits-all' and economies of scale, rather than each state having its own bespoke whatever.

Many countries around the world enjoy the benefits of coordinated public health departments. Part of the United States' poor response to COVID was because there was no central public health department that could work closely with state agencies to e.g. provide data about what's going on, share best clinical practices, etc. Each state is an island.

So no, I don't agree that the only goal of the federal government should be piggy bank. States should have a lot of latitude with their policies, but generally standardizing things across the nation would be a net positive.

Laptop brands are still trying to get away with 8GB RAM machines for general use, and especially at that value point of $200 you'll probably see 2-4GB models too.

You have a niche use-case but RAM does indeed appear to be the main bottleneck. You don't need fancy graphics, or a particularly fast CPU. You likely only need good single-core speeds.

The i5-12400 is a workhorse on the CPU front that isn't crazy old, and should do you well enough on the single core front. Pair that with 16GB of RAM and I would think you'd be set.

$1,000 might get you more if you wanted to be safe and future proof a bit more. However, RAM prices are very high right now and venturing up to 32GB of RAM might hard.

Something like this: https://www.bestbuy.com/product/asus-zenbook-14-14-fhd-oled-...

32GB RAM, nice screen, touch screen, very modern CPU (beating the 12400 benchmark). $100 under your top end of budget. It is only a 14 inch screen, great for portability, but maybe you like a bigger screen for reviewing as much content as possible?

I wonder if compilers do multiple passes on the intermediate code in order to optimize / simplify it. For example, during each pass the optimizer searches some known harcoded patterns and replaces them with something else and repeats until no possible improvement is found.

Also optimizers have a limit, they can't reason as abstractly as humans, for example:

bool is_divisible_by_6(int x) { return x % 2 == 0 && x % 3 == 0; } bool is_divisible_by_6_optimal(int x) { return x % 6 == 0; }

I tried with both gcc and clang, the asm code for is_divisible_by_6 is still less optimal. So no, there are plenty of easy ways to fool the optimizer by obfuscation.

The morale is that you still have to optimize algorithms (O notation) and math operations / expressions.

I meet with enterprise clients who explore things like Copilot Studio.

Microsoft platforms move too slowly too keep up with innovation pace, and suffer from classic platform restriction in regards to building useful, relevant, and *reliable* integrations into business systems.

My advise is to always start from scratch with AI, e.g. "build your own agent" and focus intimately on the rules/guardrails and custom tools you need for that agent to create value. A platform can't do that for you in current day.

MSFT needs to stay focused on O365 and coding tools with very simple UX wins. Not introduce custom agent platforms and auto-embed intrusive agents where no one asked for them.

> It is not illegal for them to trade on their inside information. It is illegal for you to trade on their inside information. So they can send you their stock picks list and gloat about their ROI, but if you invest on the basis of the newsletter, you go to jail.

All the Congress member trades are public. There are even ETFs now that track the Congress member trades. So you can just buy such an ETF and have a one-to-one replication of the Congress member portfolio.

I honestly don't know how you put a cone of silence around congresspeople such that insider trading anywhere in their sphere of influence is impossible. My intent would be to make it difficult for the congressperson to directly benefit from passing along insider info and compensate them enough such that it isn't a practical path. Sure, they could still tell friends to buy/sell, but if the friend *does* act on that, it's sure going to raise eyebrows when they try to wire $1M worth of proceeds to the congressperson for "movie & pizza night".

And I know that the next stone to be cast is "yeah, but if they help friends/business associates beat the market, congresspeople can still benefit with board seats and jobs when they're done with congressional terms". That's totally valid, and I have no idea how to combat that.

I would bump it to $10M/year. In terms of importance, this is still vastly underpaying these jobs.

That should take the edge off any money seeking schemes. It's hard to bribe the wealthy!

For 435 congress people and 100 senators, that adds up to $5.35B, which is about 6 hours of federal spending.
I Feel Bad
by utterdespair | 2025-12-03 15:46:35+00:00
TLDR: I feel extremely bad, any advice?

I am 25 years old and I live in southern/central Europe this year I've started my master degree program in Computer Engineering

few months ago my grandma died and I realized that the next ones to pass away in my family will likely be my parents, who are both ~60

I am 25... I am old. To put into perspective: I've already lived about a third of my life - in the best case scenario where I'll get to my older age in good shape.. but I am not mentally healthy though and with that also my physical health isn't the very best suggest me that that i won't likely get to the mean life expectancy. - 25 feels extremely old given that I never had a job. If I start today I think I could retire at 76 (lol??) and everything seems to suggest that - life won't be good in any near future in my country as the purchasing power dropped down a lot - life for computer engineers will be harder than it ever had since the industry started

not to mention that I am also struggling to finish personal projects (software and hardware related). For my friends and relatives life seems to go on while for me.. I feel like drowning.

During these last few months things seems to get worse, day by day. I can't function anymore. That's why this week I came back from my university home to my parents home.

I had my last girlfriend ~5 years ago. I'm not even bad looking - not at all, really. I just get ghosted every time I gain some confidence to ask women out.

I'm losing connections with almost all of my friends: some got into relationships, some are busy with work… others may just be uninterested in me. It's kinda painful though that no one was able to reach me out for a coffee or a beer.. just for 5 minutes... knowing how bad I am feeling lately. Also it seems that I'm not able to make any meaningful new ones: I may just become someone's "favourite new person" for ~2 days but that's it... to never be seen again the time spent together is too little to exchange numbers (although I would) but it's enough to leave me a bitter taste. The only friends I see now are friends who are having substance abuse problems and who don't seem to have real life goals. I too did abuse alcohol and prescription drugs during the last few months.

I thought that quitting drugs would make me feel better i also thought that seeing my parents and spending time with them would make me feel better the reality is that i still feel bad if not worse. and I'm losing all of my hopes for a better future, for a more bearable future.

PS. I am going to therapy - doesn't help.

Thank you for visiting this system (Number Garden). The seed space allows for 30 trillion possible systems, each with a size of 11! × 11! (39,916,800 × 39,916,800) cells. Breathtaking constellations don’t always appear immediately—you often have to search for them a bit. You can do this by double-clicking or pressing the ‘N’ key.

A major feature here is that you can move the visualization itself—hold the mouse button down and drag, or press the ‘M’ key. It takes roughly 30 hours to reach the edge…

This is, of course, also generative art, but beyond that it’s a highly refined and meticulously engineered application. I’ve spent countless hours working on it, exploring, refining, and pushing the system further.

These days I am just assuming it is textures. Textures for graphic quality, that I don't need on my merely full HD screens. Makes me usually not even bother buying, let alone installing such a game. Even 23 GB is still tons. When I compare that with how much fun I can have playing games that focus on gameplay instead of graphics, I would rather safe money, than spending it and having to go through my files and delete things, because I need more space for a game.
