the Rwandan genocide took place between 7 April to 19 July 1994

it's been only ~6 months or so since Trump took office and he's already annihilated the US Fed Gov and is now declaring martial law.

and he's concerned with appearances, sorta. AI won't be.

smoking and hormone supplementation are by no means independent variables when studying cancer risk. You might normalize for them by only comparing smokers with smokers or oral contraception users w other oral contraception users, but a study like that gets very complex when you have to compare smokers who exercise but use oral contraception, don't drink and are vegetarian vs smokers who exercise but use oral contraception, don't drink and are omnivores and I see no indication in the article that any of these variables were normalized for.I think you're right, the second paragraph is a warning and the word "impossible" was chosen deliberately.

> Wouldn't having them already up give a lot less warning in a first strike situation?

From GEO, no. From LEO, still probably no.

There may be a bird positioned just right so a small deörbit burn pots Moscow quicker than an ICBM could. But the moment you start burning, you’re caught. (Same as an ICBM.) And unless you have a really obvious orbital configuration that bunches a bunch of birds in a way useful for practically nothing but such a strike, you only get one or two such “early” shots before a wall of ICBMs would have landed.

Nukes in space aren’t about nuking the ground from space. It’s about space area denial through EMP.

ChatGPT 5 did argue with me about something math related I was asking about, and I did realize I was wrong after considering it further.

I don't actually think being told that I have asked a stupid question is valuable. One of the primary values, I think, of LLM is that it is endlessly patient with stupid questions. I would prefer if it did not comment on the value of my questions at all, good or bad.

> uv pip install --system torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu118

uv has a feature to get the correct version of torch based on your available cuda (and some non-cuda) drivers (though I suggest using a venv not the system Python):

> uv pip install torch torchvision torchaudio --torch-backend=auto

More details: https://docs.astral.sh/uv/guides/integration/pytorch/#automa...

This also means you can safely mix torch requirements with non-torch requirements as it will only pull the torch related things from the torch index and everything else from PyPI.

LLMs by their nature don't really know if they're right or not. It's not a value available to them, so they can't operate with it.

It has been interesting watching the flow of the debate over LLMs. Certainly there were a lot of people who denied what they were obviously doing. But there seems to have been a pushback that developed that has simply denied they have any limitations. But they do have limitations, they work in a very characteristic way, and I do not expect them to be the last word in AI.

And this is one of the limitations. They don't really know if they're right. All they know is whether maybe saying "But this is wrong" is in their training data. But it's still just some words that seem to fit this situation.

This is, if you like and if it helps to think about it, not their "fault". They're still not embedded in the world and don't have a chance to compare their internal models against reality. Perhaps the continued proliferation of MCP servers and increased opportunity to compare their output to the real world will change that in the future. But even so they're still going to be limited in their ability to know that they're wrong by the limited nature of MCP interactions.

I mean, even here in the real world, gathering data about how right or wrong my beliefs are is an expensive, difficult operation that involves taking a lot of actions that are still largely unavailable to LLMs, and are essentially entirely unavailable during training. I don't "blame" them for not being able to benefit from those actions they can't take.

> That's kind of insincere and dishonest on your part,

Ad hominem attack - great.

> This is copyright violation, not theft.

I'm arguing it's copyright violation because it's theft of revenue. If it didn't result in any loss of revenue then it would hard to argue it wasn't fair use.

Note I'm not using theft in any special legal sense - just in the common sense English sense.

If 'learning their style' included incoporating large recognisable chunks - that smart kid would fail his English degree on plagarism grounds.....

The point about LLM's is they an do everything - from an unrecognisable 'original' mashup - to what are quite clearly regurgations of the input. Note also that the kid didn't steal the books he learnt from.....

The question is what's happening fair and good for society, not what is convenient for some very well funded companies in a hurry who see existing laws as annoying things getting in their way, rather than something to respect.

You are 100% right, we have messy incompatible systems because there is no standardization. It is arguable that standardization of something that is so subjective is always going to be problematic. Design patterns are invented all the time and they start to infect other applications/platforms and mutate over time.

The only reason the original post think that "used to be a solved problem" was because we used to have a standard for guis: win32. But obviously people wanted more powerful/flexible UIs and more importantly, cross platform guis so it eventually died off.

A lot of design innovation came because the web is extremely flexible while at the same time being extremely non-standardized.

Was just going to write more or less the same thing. A second home (especially far away) is a huge expense, not a financial investment. Whether or not that expense is worth it (e.g. as a place to create good memories) is a very different prospect than real estate as an investment.

We rented the same vacation house for many years - it was way less expensive than owning the place. Recently it was re-zoned to be in a flood plain - that would have completely killed the place as an investment.

We could have bought the house BTW, but instead invested the money in stock and bond index funds. That turned out to be a really smart move. We still have the great memories, and don't have the ongoing headache of a far-away property to maintain.

The CCTV cameras I've never really had a problem with - despite what TV shows and films would like to tell you they're not actually a single coherent CCTV network, a vast proportion of them are operated by random shopkeepers, private home owners, and other such places. If they want footage from them the police are typically going to have to send someone out to ask for it, and then hope they haven't reused the storage already.

This sort of thing, deploying facial recognition systems in the street in the hope of finding someone, is much more insidious. Technically you can choose to bypass it, or pull something over your face, but that's more or less guaranteeing that you'll be stopped and questioned as to why you're concerned about it.

Sadly the UK never met an authoritarian they didn't like (apart from Hitler, so long as you're not as bad as Hitler himself you're good though). When surveyed the British public will call for banning basically anything they don't like, even if it doesn't impact them at all.

> Back then people were happy if they got models to write a small simple function and it worked. Now they expect models to manipulate large production codebases and get it right first time.

This push is mostly coming from the C-level and the hustler types, both of which need this to work out in order for their employeeless corporation fantasy to work out.
GEPA Agent Optimizer with Lakshya A. Agrawal [podcast]
by CShorten | 2025-08-13 14:05:22+00:00
I am SUPER EXCITED to publish the 127th episode of the Weaviate Podcast featuring Lakshya A. Agrawal!

Lakshya is a Ph.D. student at U.C. Berkeley, where he has lead the research behind GEPA: Reflective Prompt Evolution can Outperform Reinforcement Learning!

GEPA is a huge step forward for automated prompt optimization, DSPy, and the broader scope of integrating LLMs with optimization algorithms!

The podcast discusses all sorts of aspect of GEPA from the Reflective Prompt Mutation to Pareto-Optimal Candidate Selection, Test-Time Training, the LangProBe Benchmark, and more!

I learned so much from discussing these things with Lakshya, and I really hope you enjoy the podcast!

As a Brit my feeling is that the state has basically given up on the concept of doing the right thing (not even from an ivory tower moral perspective, but from a realpolitik grow the economy / fix the issue sense) and is just throwing sticking plasters everywhere.

The recent issues with crime are, at root, apparently down to the fact that we don’t have enough prison places and we don’t have enough police.

The obvious solution is to hire more police, raise the wages, compulsory purchase a big field somewhere, make a massive prison and lock up the worst offenders for a long time.

There is some obsession with “making the books balance” as if this even matters. The Government is sovereign but acts as if somehow they have to do everything at market price like a private individual would.

No, on top of social security „taxes“, you also have something like 140 billion euro substitutions to pensions from income tax money, as far as I know. On top you get increased healthcare costs, cause boomer also get sick at that age. So young, working people pay thrice for their lifestyle. And in particular, those 140G€ are not spent on infrastructure and Germany’s future. Coincidentally, social welfare is a fraction of that, but aaall the rage to those boomers, who benefited from low taxes and high pensions, while spending 40 years in ignorance of their generation’s demographic burden.

Don’t forget, we got a young generation severely hurt because of COVID restrictions on their social life and education at the most critical time. That generation had the least to worry about the plague, it’s been pure sacrifice for old folks, who were the ones slowly suffocating in bursting emergency rooms. Two years of death and struggle and demographic crisis no more, but we were kind and compassionate, hidden behind webcams and masks at the prime of our youth. The boomers’ gratitude was shown by completely ignoring the climate crisis, the housing crisis (guess who got the houses…), the immense infrastructure debt, and instead increasing taxes etc., and of course making culture wars and hatred their scapegoat. The most egotistical generation ever.

Not remotely. It’s not even logical.

From an employees standpoint, most of the employers weren’t profitable and when they went out of business, employees weren’t having a hard time finding a job.

But honestly, it was only people working for “tech” companies. I was working in Atlanta as a Windows developer with four years of experience working for a boring old bill printing company. Other profitable enterprise companies were still hiring like banks, insurance companies, airlines, etc.

Today, all of the major tech employer’s are trillion dollar profitable companies with real businesses that are not dependent on Gen AI. They have been using machine learning forever and still will.

Every company doesn’t need to be a software development shop. But every company doesn’t need to be into data analytics.

On the other hand, from the investor’s standpoint, the only publicly traded company that will live or die by AI is Nvidia - and Tesla which has always been a meme stock. If investor money is lost in the private market, who cares?

Yes I know that there is a push to allow private equity investing in 401K plans and pensions. I really only have sympathy for pension fund holders who don’t have a choice.
Show HN: JustMySaaS – A growing collection of small web tools I built
by devxiyang | 2025-08-13 14:06:58+00:00
Hi HN,

I’ve been building small, focused web tools over the past months, and decided to put them all in one place: https://www.justmysaas.com

Each tool solves a simple problem and is ready to use instantly—no signup, no onboarding. Examples include: •Carousels Maker – create image carousels for social posts •Twittethread – turn plain text into nicely formatted Twitter threads •ShipNow Basic – quickly set up a simple product landing page •…and more, with new tools added regularly

I made this as a personal playground to quickly turn ideas into something usable, and to keep shipping instead of leaving projects half-done.

Would love feedback on: •Which tools feel useful (or useless!) •Any small tool ideas you’d like to see added •UX/performance issues you spot

And unless they've improved it, NY Connections doesn't have nearly enough red-herrings to be interesting.

The difficulty with the Only Connect wall is that you can have 5 sets of 5 or more in each, and sometimes can have loads that could fit a category, e.g. you might have 7 or 8 Pixar Movies listed.

You know that's going to be a category, but you also know it's a waste of time to try them before finding other categories.

There's also linguistic and add/drop letter ones, so if you see "Soul", that might actually be "Capitols missing a letter", "Stars with an extra letter", or "Homophones of Fish".

But it might be straight, so could fit "Davids", "Pixar Movies", etc.

There is a meta-pattern, you typically only have one such missing/add letter group on a wall, and you typically have one "Names" (often common firstname) set. Places in general also feature very regularly, especially with missing parts.

Fully solving most walls in the time limit is extremely challenging. It's slightly easier for the home viewer on the second wall, because there are often common themes across the two walls, but of course the competitors don't get that help.

Finns need to mentally evolve beyond this mindset.

Somebody being polite and friendly to you does not mean that the person is inferior to you and that you should therefore despise them.

Likewise somebody being rude and domineering to you does not mean that they are superior to you and should be obeyed and respected.

Politeness is a tool and a lubricant, and Finns probably loose out on a lot of international business and opportunities because of this mentality that you're demonstrating. Look at the Japanese for inspiration, who were an economic miracle, while sharing many positive values with the Finns.

I can't seem to authenticate because it had a localhost URL in the address when I was first authenticating. Now my work laptop has blocked the site completely to sign in or anything at all due to the activity of rapidly trying to bypass a site with no certificate because of that pass-on or something. Bummer, this computer has some more juice vs mine!

> The artist is unknown but the date of composition is given as 1580, which is several years before Mary was executed, so the transformation into a skull seems a little premature.

Mary Queen of Scots was imprisoned by the English for about 19 years before her execution and was pretty unpopular in Scotland during that period. So it is entirely possible that her morphing into a skull was intentional.

Does America have the economic, social, and industrial resources to wage such warfare with the cartels?

America has spent trillions on two failed wars in the past 25 years, and lacks the economic capability to produce artillery shells to aid Ukraine.

At the same time it needs to build up industrial capacity to defend against an impending war in the pacific and it doesn't seem to be able to do that.

It is unlikely that engaging in all out war with the cartels is a viable path at this time.

Anecdotally it seemed 5 was briefly better about this than 4o, but now it’s the same again, presumably due to the outcry from all the lonely people who rely on chatbots for perceived “human” connection.

I’ve gotten good results so far not by giving custom instructions, but by choosing the pre-baked “robot” personality from the dropdown. I suspect this changes the system prompt to something without all the “please be a cheery and chatty assistant”.

> If you are looking at human psychology? Looking at existing data in new ways is essentially p-hacking.

I agree that the type of analysis is important, as is the type and quality of the data you're analyzing. You can p-hack in cosmology too, but it's not a quality argument there either.

> And you probably won’t ever have enough data to define a “universal theory of the human mind”.

I think you're underestimating human ability to generalize principles from even small amounts of data [1]. Regardless, my point was more specifically that we could use existing data to generate constraints to exclude certain theories of mind, which has definitely happened.

As part of the AI insanity $employer forced us all to do an “AI training.” Whatever, wasn’t that bad, and some people probably needed the basics, but one of the points was exactly this— “use negative prompts: tell it what not to do.” Which is exactly an approach I had observed blow up a few times already for this exact reason. Just more anecdata suggesting that nobody really knows the “correct” workflow(s) yet, in the same way that there is no “correct” way to write code (the vim/emacs war is older than I am). Why is my bosses bosses boss yelling at me about one very specific dev tool again?

Not only that, but if a tractor encounters an obstacle in the field that it doesn't know what to do about, it can simply stop right where it is and wait for human intervention, unlike cars where you don't want them stopping dead in the middle of the road. Also tractor speeds in fields are far lower than cars on roads, so automatically a huge safety advantage there.

You're correct, there are some more sophisticated processes used by specialty printers such as CcMmYK (https://en.wikipedia.org/wiki/CcMmYK_color_model). Something like this will use more inks and less halftones, giving better results in some cases.

Or are you referring to other printing methods, say for example silk screening? There, you would definitely select a specific ink to use. It just depends on what your goals are.

You can exploit the exactness of (specific) floating point operations in test data by using sums of powers of 2. Polynomials with such coefficients produce exact results so long as the overall powers are within ~53 powers of 2 (don't quote me exactly on that, I generally don't push the range very high!). You can find exact polynomial solutions to linear PDEs with such powers using high enough order finite difference methods for example.

However, the story about non-determinism is no myth. The intel processors have a separate math coprocessor that supports 80bit floats (https://en.wikipedia.org/wiki/Extended_precision#x86_extende...). Moving a float from a register in this coprocessor to memory truncates the float. Repeated math can be done inside this coprocessor to achieve higher precision so hot loops generally don't move floats outside of these registers. Non-determinism occurs in programs running on intel with floats when threads are interrupted and the math coprocessor flushed. The non-determinism isn't intrinsic to the floating point arithmetic but to the non-determinism of when this truncation may occur. This is more relevant for fields where chaotic dynamics occur. So the same program with the same inputs can produce different results.

NaN is an error. If you take the square root of a negative number you get a NaN. This is just a type error, use complex numbers to overcome this one. But then you get 0. / 0. and that's a NaN or Inf - Inf and a whole slew of other things that produce out of bounds results. Whether it is expected or not is another story, but it does mean that you are unable to represent the value with a float and that is a type error.

Because every s-curve looks like an exponent for those in the start.

I mean look at the first plane, then first air-jets: it’s understandable to assume we would travel the galaxy in something like 2050.

Meanwhile planes are basically the same last 60 years.

LLMs are great but I firmly believe that in 2100 all is basically the same as in 2020: no free energy (fusion), no AGI.

This.

I am still thinking and trying to figure out what the new concepts i.e social media, streaming, etc, of the AI era will be. There are of course the extrapolations of existing concepts, e.g shopping just like it adapted to the internet world will adapt to the AI world and you'll have a few companies there -- equivalents of uber, amazon, zomato, etc (or maybe those companies themselves).

Products with no margin such as translation will of course get a million times better, but I mean in terms of economic value.

> about to ask people to donate, but they have $80k in their coffers

I'd still ask folks to donate. £80k isn't much at all given the time and effort I've seen their volunteers spend on keeping the lights on.

From what I recall, they do want to modernize their build infrastructure, but it is as big as an investment they can make. If they had enough in their "coffers", I'm sure they'd feel more confident about it.

It isn't like they don't have any other things to fix or address.
