When finance folks come up with creative solutions to problems, bad things happen.

Here the “problem” is that these AI companies don’t have enough money to buy things and the traditional pool of investors that would give cash and then sit on the sidelines has dried up. Normally in that scenario companies just go bust.

To keep throwing fuel on the fire suppliers are stepping in the “invest” so AI startups can buy the supplier’s goods. History says that’s a terrible idea.

Markets correct craziness in the end, everyone will wonder how this mess ever happened, hearings will be held, and a range of new regulations will be introduced to prevent this sort of thing from happening again. Then finance folks will come up with some new way with finance to be less boring and the cycle brings anew.

> Could lead to significant efficiency gains for EV's

Not really. EV's are very heavy from non-motor weight. A Model Y weighs ~4300 lbs. A motor that is 75 lbs lighter is a 1.7% savings. That's not nothing, but I wouldn't say "significant". You can do better by swapping for fancy wheels or eliminating some of the glass roof.

And really this is true up and down the electric vehicle world. Weight-sensitive applications are always going to be completely dominated by battery weight. Making the motor smaller just isn't going to move the needle.

Basically this is good tech without an application, which is why it's having to tell itself with links like this.

I think there is a small subculture who still wants to go deeper into online living. But it is very small. Most people are weary of the always-online culture social media brought, and AI is making online life worse, not better. A metaverse would absolutely appeal to that tiny crowd that disagrees, while most of the world would, frankly, find it cringe.

Whether or not you want to create something that only appeals to a small tech subculture is something you need to decide for yourself, but with a vague ask of "is it worth it?", without knowing what your actual goals are, I gotta just say: "No."

Automatization reducing work can actually be a good thing, as it is the reason why we can have vacations, retirement and long studies: because the society's need for work is lower than before.

> seeing how these giants all have incestuous relationship with each other makes me uneasy about putting money in the markets

If you invest in index funds (instead of picking single stocks), you shouldn’t be too worries IMO.

E.g. something tracking MSCI World/All-World or just the S&P500 (US-only though).

You won’t get 100x homeruns (more like 10-15% avg returns/year), but you will drastically lower your risk of losing your money.
Show HN: I built a tool that finds gaps in medical research
by rohma_said | 2025-11-03 12:33:52+00:00
I built Research the Gap, a free tool that maps medical papers on a grid using two of six research dimensions (Population, Methodology, Independent Variable, Outcome, Setting and Study Location). Green means well-studied, red means barely touched.

The idea came from a simple question: where do I find a research gap?

What do you think? And does the name make sense? Research the Gap, like Mind the Gap?

I recently listened to a podcast episode about Enron, and one of the red flags was that they reported profits on paper, but didn't generate cash flow proportional to their profits.

Both Amazon and Nvidia probably don't need the cash flow right now, which is why they can get away with it. It'll be interesting to see what happens if their cashflow ever runs dry.

It will be interesting to see if Qualcomm end up deploying an open sourced standards compliant UEFI implementation. This would be a big deal in my eyes as the Raspi firmware solution is really a pain in the butt to deal with as it's closed source and the documentation is very fragmented and hard to comprehend if you're doing anything beyond their recommended approaches (for example, trying to use an A/B update scheme on a Raspi CM 5 with proper failed boot fallback is not straight forward without resorting to using u-boot as well).

There are some theories like HoTT where it's convenient to let the same terms act as proofs while still having computational content and sometimes a distinct identity ("proof relevance"). For example a "proof" of isomorphism that might be used to transfer results and constructions across structures, where isomorphisms can be meaningfully distinct. Of course you do retain a significant subset of purely logical arguments where no computational content is ever involved and "identity" becomes irrelevant again.

> narrative information through sequences of knots

It's unlikely any complex narratives could be encoded there, though.

Possibly a bit like the e.g. the Mycenaean Linear B script. Which is fully decoded and well understood. But despite having a full fledged writing system they mainly used it for accounting and such. They can tell us about how many goats, sheep and various good they had they had but don't tell as much about the society or history as such.

Heculaneum manuscripts are kind of the opposite from the Quipu in the sense that we have zero issues understanding the actual text/symbols just extracting them from the destroyed scrolls is rather complicated.

Minoan tablets are maybe a bit closer and little progress has been made there (then again we are fully capable of reading the script just have no clue about the language it was written in).

One has to think in different terms in signal to utilize analog. Think collisions in waves that cohere. We can’t have an end goal in hardware dev unless we have an existing software that crudely maps to the goal. We use such imprecise ideas in hardware to compute, they’re arbitrary. Our computers are still at the toy stages. Neural nets are toy models. Think organ stage.

OK, but why launch it as a web page? Different people inputting the same topics are just going to be repeating each other's work. And people who are in a position to engage in new research to resolve the gaps are highly likely to already know their own fields well enough to not need this tool.

It would seem to make more sense for this to be a background process, publishing its results.

Like in 1929 or 1999 everyone knows it is a bubble, but always thinks they're the rational one who can ride the rollercoaster up and time the bubble, then sell before it pops.

It is the same psychology behind meme coins. Everyone knows they are worthless, they gain value because everyone is trying to make everyone else the greater fool holding the bag.

2008 was less a bubble of irrational exhuberance and more a bubble of overvaluation enabled by fraud of bundling bad mortgages into A rated investment products

A sufficiently compact electric motor enables mounting it in the nose-wheel of commercial aircraft, allowing it to be driven around like a golf cart. This means the plane can taxi without the use of its engines, just the power from the APU. [1]

Also planes would not have to wait for a tug to pull back from the gate, which improves turnaround times for the airline.

It's not a fraction of what it would cost to actually employ those humans, since there were humans who clearly chose to do that work when presented with the opportunity.

I think this is a very first-world oriented take. It efficiently distributed low-value workloads to people who were willing to do it for the pay provided. The market was efficient, and the wages were clearly on par with those who were doing the work found economical to do, considering they did (and still do) the work for the wages provided.

I switched from MathJax to KaTeX earlier this year for my blog. So far, it has been working out well.

The only feature I really missed was the ability to use \label and \eqref for equation referencing, since KaTeX doesn't support these commands [1]. I worked around this limitation with a small custom setup defining my own \label and a custom \eqnref (not exactly \eqref though) [2].

Another thing that bothered me a little was that the KaTeX autorender extension does not recognise \begin{align*}, \begin{alignat*}, etc. as top-level delimiters by default [3] but this was trivial to fix by customising the set of default delimiters [2].

I know KaTeX supports server-side rendering but I don't use that yet [4]. I still use client-side rendering. Despite that my maths pages [5][6] render quickly since they are usually small, with only a single reflow from the initial load to the rendered page, without the continual reflows or jitter I used to see with MathJax. Overall, I am quite happy with the switch from MathJax to KaTeX.

I had received a video call request from a German asst prof after I had applied for CS MS and a full scholarship to his department. I had written back saying I'd be okay with that and had asked whether he could tell me what it was about. He was upfront: "English proficiency satisfaction call" (yup, verbatim). 2-3 minutes into the call, he chuckled and said, "okay okay I am satisfied with your English". He was from Eastern Europe, and English wasn't his strongest suit, and he had to ask for meanings a few times. I am from an ex-GB colony. Anyway he mentioned that his department (and no other department there) faced a lot of situations from this part of the world where applicants had perfect GRE and TOEFL/IELTS scores but in reality they struggled with communication, and with laughter he added, "and your score had a big red flag". Mine were not perfect; just that my TOEFL and GRE verbal scores were at odds.

I missed goto when I was 10 and had to stop using it because I moved beyond writing BASIC on an Apple ][.

I got over it.

I did have to use it in error handlers in Lotus Notes apps back in the 90s/00s, but that didn't make the apps better, it just was how the scripting worked. I haven't once felt the need for a goto since then.

So unless you can tell us a scenario where they work better, no - they are not needed and would cause more harm than good.

Not arrogant, just a fact of life.

In the same way that the average Dutch palate is content with food produce of mediocre quality and taste, and is satisfied with food that would make the average French or Italian wince.

Being discerning about the quality of your food is something you pick-up intuitively from birth. Some cultures have it, others don't.

Death is a health risk.

So are cholera and other diseases accompanying flooding.

And other factors associated with reservoirs: desertification and lake evaporation can lead to increased dust, common where water is diverted or impounded (Aral Sea, Lake Powell, Lake Mead). Disruption of silt flows has various impacts, more on the general environmental side.

Generally, if your concern is overall mortality risk rather than a specific disease/pollution mechanism, dams do not get a free pass.

That is one hell of a gloss over of the the previous 500-600 years before the Inquisition and massively over-simplifies what happened. There wasn't really a Spanish state either, certainly not as we would understand it today.

At least for the 5 the compromise was motivated, in the second case i just don't feel like the low performance is a worthwhile compromise.

> had just gone through several centuries of horrific mass-murder of non-Christians in Spain,

Well it varied, but such behaviour was not strictly unique to Spain in those days. Being a Catholic in England wasn't terribly exciting either.

Then you have the witch hunts across must of Europe which resulted in probably well over 10x times more people being murdered in Germany alone compared to the inquisition and they weren't really a thing in Spain.

In a way the Spanish Inquisition was quite similar to the NKVD or the Gestapo/etc. since the persecutions were usually intended to impose ideological/social conformity (or inherently racist in how it targeted even perfectly honest Jewish or Muslims converts) rather than "ritualistic".

Of course Christian Spain is interesting in the sense that it turned from one of the most of tolerant societies in Europe to the one of the most intolerant ones in a couple of centuries.

e.g. during the Almohad invasions you had Christians, Jewish and even moderate Muslims fleeing to the Christian kingdoms which generally were much more tolerant at the time.

> Can you see how this absurd double standard may come across as racist?

That's not particularly new in Europe though. e.g. the Greeks and Romans found Carthaginian mass child sacrifices extremely abhorrent yet at the same time didn't see much of an issue with "exposing" unwanted infants. Treating violence due to economic/utilitarian/political reasons differently that doing it for ritual/religious reasons was is still pretty ingrained into western culture.

Yes, by current approach I mean security best practices for non-LLM apps. Plenty of those are directly applicable.

And yes, LLMs have some challenges. But discarding all of the lessons and principles we've discovered over the years is not the way. And if we need to discard some of them, we should understand exactly why they are no longer applicable.

EDIT: I know that models need to omit stuff to be useful. But this model omits too much - claiming that something is "safe" should be a red flag to all security workers.

> Windows locks files when they're in use, so that you cannot overwrite them. Linux doesn't do this.

Linux does do this (try overwriting or truncating a binary executable while it's running and you'll get -ETXTBSY).

The difference is that Linux allows you to delete (unlink) a running executable. This will not free the on-disk space occupied by that executable (so anything you write to disk in the immediate future will not overwrite the executable, and it can continue executing even if not all of the executable has been paged in) until all references to its inode are freed (e.g. the program exits and there are no other hardlinks to it).

Then you can install a new version of the executable with the same name (since a file by that name no longer exists). This is what install(1) does.

e-bikes don't necessarily need more power but they could benefit from a smaller and lighter motor. If it becomes small enough to "disappear" in the pedal assembly for example, it would allow more design/parts commonality with normal bikes and fit more people's aesthetic criteria.

The lower weight would be definitely welcome, my ebike is comically heavy compared to a normal one and sometimes I have to carry it up flights of stairs (some German railway overpasses, grr).

Also in scooters it could fit in the wheel (since the wheel is tiny and has to spin quite quickly - no reduction gear needed vs a bike with 26-28" rims) allowing a simpler design and cost savings. But maybe in scooters they're already using in-wheel motors, I'm a bit ignorant there.

Windows won't let you overwrite files "in use" and "file" is determined by the full pathname.

Linux will let you overwrite files "in use" (though the program(s) using them may not notice) and "file" is determined by a magic number, the inode - you can delete a file from a directory, really it's removing _that inode_, and put a new file in place with the same name, it's a _new_ inode. Programs that still have the file open are referring to the _old_ inode, which only goes away once everyone stops using it.

So actually you need to go round restarting your programs/services on Linux to get them to pick up changes (most package managers do that automatically), but at least it's _possible_ to make those changes without a reboot. Windows has to go into a special mode where nothing else runs, to be sure that it can update files.

You can only realize the tax if the stock owners sell the stock (vs. giving them a dividend which triggers the tax on payment). It is more of a tax delay but since many people who bought these stocks have more money than they need, they no longer need to sell and they don't need the dividends much. So a buyback is just injecting that money back into their shares tax-free.
