AFAIK, Electron holes refer to the P-type charge carrier in a semiconductor lattice where the absence of electrons behave similar to electrons in an N-type semiconductor. Benjamin Franklin was not concerned with solid state physics rather he's referring to the charge carrier in a conductor being positive when we later discover that its negative (electrons). When current flows through a conductor its just electrons (not holes) moving from negative to positive.

I think you are coming from a good place, but it is better to not compare our imaginary and implausible concerns (like discovering we’re a giraffe or from another planet) with real problems that people might actually have. I think you actually would have a lot to think about if you found out that you were a giraffe, but we don’t really have to seriously contend with that possibility or what it means.

Yes, it is good to remind people that we continue to be ourselves whatever we discover about ourselves. But, we should also be upfront about the fact that some of us are going to end up with real identity issues at some point.

It’s a well known fact if you’re remotely interested in cars. Mazda has supposedly upped their game lately regarding rust, but they and other Japanese brands are still regarded inferior to Volvo/german cars in terms of falling apart to rust in our Nordic climate.

You can use car.info to if you want to dig further on this (statistik på skrotade bilar). Or just ask your favorite LLM. You don’t have to take my word for it.

Japan doesn’t salt their roads nearly as much as we do.

> LLMs reduce a very high-dimensional vector space into a very low-dimensional vector space.

What do you mean? There is an embedding size that is maintained constant from the first layer to the last. Embedding lookup, N x transformer layers, softmax - all three of them have the same dimension.

Maybe you mean LoRA is "reducing a high-dimensional vector space into a lower-dimensional vector space"

You can have "cat" as 1 token, or you can have "c" "a" "t" as 3 tokens.

In either case, the tokens are a necessary part of LLMs. They have to have a differentiable representation in order to be possible to train effectively. High-dimensional embeddings are differentiable and are able to usefully represent "meaning" of a token.

In other words, the representation of "cat" in an LLM must be something that can be gradually nudged towards "kitten", or "print", or "excavator", or other possible meanings. This is doable with the large vector representation, but such operation makes no sense when you try to represent the meaning directly in ASCII.

Do you let your pans heat up before use? Do you let your pans slowly cool down instead of dunking them in cold water?

I haven’t had a pan warp on me for years just being mindful of letting it heat and cool at a reasonable paces rather than blasting them with the ”power” mode. And this is in Europe with our 400v kitchen outlets.

Wouldn't sexually active people who have sex with men be the primary market? It makes sense this would be the focus of the drug's development.

They may also have issues trying to conduct robust clinical trials with IV drug abusers. If a subject entered rehab or were incarcerated for a period of the trial, would that invalidate their data? I don't know enough about the subject but it intuitively feels like it could present a real challenge.

I must admit the amount of pornography in different forms is now apparently everywhere on social media. Including social media I thought was "safe":

I see videos that I think are overtly sexual in nature on YouTube, even if the video is something supposedly "innocent". If you click through to their profiles there is an inevitable link to 18+ content most of the time. I am subscribed to only tech/film/gaming channels on youtube and this content is now always put into my feed. I probably have cursed myself by checking these people's profiles after the fact.

You are right though that by bandwidth, streaming services including Netflix make up the majority of data over the Internet and it is not pornographic/dangerous for children at all.

I came across this video a while back of someone programming Blender by sharing his screen on Google’s AI Studio, and essentially hacking together a bunch of automated scripts, prompts and macros to feed Python scripts into Blender’s console and using that to manipulate 3D objects. The end result makes it look like he is using just his voice to build on Blender. I found it extremely impressive, and there is probably massive alpha in just simply tightening this loop and making it a seamless experience where all you have to do is open the app, talk to it, and watch your 3D object get sculpted.

Trump has signed a number of bills aimed at ramping up the nuclear center, which is the best-available renewable energy source based on current tech, aside from geothermal, assuming recent developments continue to pan out.

The only country that the US needs to worry about beating them in the clean energy race is China. They’re building energy plants like crazy (though worth noting, not all of their plants are clean energy).

Bash isn't better.

because I write and run such scripts.

Microsoft wouldn't suffer, PowerShell users would suffer.

In this scenario the PowerShell team has been defunded or sacked. Who will the bug report go to? Who will implement the feature request?

Users are interacting with Microsoft for feature requests and bug reports. There are a thousand open issues on https://github.com/powershell/powershell/ and many more which were closed "due to inactivity". What difference does that make if Corporate doesn't want to fund a bigger team to fix more bugs unless it can be shown to benefit a lot of customers not just "a few" devs who raise issues?

Perhaps my wording was the problem, and I didn't ignore your other question, I said the percentage isn't the problem, I also don't know the number, but I'm sure you do.

Perhaps it was a problem with my wording but your statement about the daily mail suggests you've entirely misunderstood me, but to be specific I'm generally left leaning and prefer broadsheets, though I currently mostly use aggregators to combine sources to find where the facts are as opposed to "cliche talking points".

I thought I was clear when I said that the effect on my wallet is where my opinion is formed, but it seems you might have missed that.

I have no problem with paying more tax as a higher earner, but I don't agree with a tax system that literally prevents me from earning a penny more and would even have me earn less unless I can find a significant jump.

You clearly have a different view on this but the facts of what I see right in front of me have little to do with talking points and consensus and everything, right now, to do with tax or the tax system.

I'm taxed too much on every penny I've earned over over £99,999 and way too much because of the privilege of having pre-school aged children, that's my opinion, agree or not.

I'm merely responding with the bad faith reading you're presenting here, as woman is a squishy and cultural word to describe an additionally squishy biological set of states. At no point does the article declare them not to be women, only that they are women with genetic conditions from having a Y chromosome (or even just a section of the Y chromosome), a shorthand of which they call "genetically men".

"Brittle" here means either:

1) your test is specific to the implementation at the time of writing, not the business logic you mean to enforce.

2) your test has non-deterministic behavior (more common in end-to-end tests) that cause it to fail some small percentage of the time on repeated runs.

At the extreme, these types of tests degenerate your suite into a "change detector," where any modification to the code-base is guaranteed to make one or more tests fail.

They slow you down because every code change also requires an equal or larger investment debugging the test suite, even if nothing actually "broke" from a functional perspective.

Using LLMs to litter your code-base with low-quality tests will not end well.

Unless there's a fundamental change in how the technology works, it'll never get to the point you're talking about. We're still waiting on our self-driving cars, remember.

Also, when it comes to music, who are the people in the rock and roll hall of fame? Those who can play the guitar real good? Or those who crafted songs that people love? AI will never be able to do the latter. But, AI can play power chords better than any session guitarist. That session guitarist is going to have to learn how to compete in another way than his guitar playing skill.

Show HN: Edifest.fyi – browse the Edinburgh Fringe with embeddings and MCP chat
by benesing | 2025-07-28 17:10:33+00:00
I didn't know how absurdly large the Edinburgh Fringe was until I performed there. In roughly three weeks, there are about 3800 shows and more than 50,000 performances of those shows.

That inspired me to start a SaaS for festival schedules, and this is my new site for navigating the Fringe as well as the other festivals in Edinburgh (as if it wasn't big enough already).

The site is using embeddings for semantic search, so "comedy duo about fruit" has some surprisingly relevant results. The assistant has MCP tools for the same search as well as geo coordinates, and it's been making very good suggestions, schedules, and conversations.

A big thanks to Festivals Edinburgh for making the data available.

Happy to answer questions about it!

> Mediocre men-who-purport-to-be-women beating outstanding actual women, is analogous to a mediocre athlete juicing to beat his more talented competitors.

Does this actually happen? I remember seeing the first transgender woman competing in weightlifting, on the olympic stage. So like the most elite of the most elite competition, in a sport where you'd think muscle mass, skeletal size, and testosterone would matter the most. And she finished dead last. I'm not like a huge follower of sports or anything, I just follow the olympics sometimes. I never see transgender people dominating anything there and certainly not to the extent of Michael Phelps.

If we want to remove people due to lack of competitive fun we can remove Phelps, it was always really boring watching anything he competed in.

It’s not - there are tons of places with no access to swimming. It also has less to do with urban/suburban. If anything, urban is likely to get more, as they can potentially reach public pools.

It’s about access to water. If you parents don’t take you, if there are none around to naturally discover, if there are none around which you personally have access to, you don’t learn to swim.

If you do, you typically do. Simple as. I really do not understand why people seem to think everyone has a pool. You can tell many of the people in this sub grew up middle class at least!

The median wait to be seen by a specialist is currently 14 weeks, but the range is much larger and some patients will wait as much as a year for a non-urgent referral. Those waits are on top of a lot of de-facto rationing; referrals will often be rejected for fairly spurious reasons, purely to manage demand.

Speaking personally, the biggest issue isn't the waiting, but the chaos and uncertainty. Every part of the NHS is in a constant state of crisis management. I don't terribly mind that I usually have to wait about two weeks to see my GP (family doctor), but I do object to the fact that I'll invariably be seen by a locum (temporary) doctor who doesn't know how the local systems work and won't be there if I need a follow-up appointment. I could live with waiting lists if they were always 14 weeks, but it's incredibly disruptive to not know if it might be 14 or 40 weeks, to not know if your long-awaited appointment will be cancelled with no notice due to staff shortages or industrial action. I've almost got used to the fact that the corridors of my local hospital are permanently full of "temporary" overflow beds, primarily occupied by frail elderly people, often in considerable distress, sometimes obviously neglected.

I'm fairly high-agency and I feel that the system is hostile and difficult to navigate; I have no doubt that many patients who are less able to advocate for themselves suffer preventable deaths because they fell through the cracks.

> The UK is becoming increasingly authoritarian in ways that feel increasingly antagonistic to the majority of the population, regardless of political party. Taxes are rising (with tax take falling), crimes are going unchecked, just mentioning increased immigration gets a lot of people's backs up, but as GDP per capita continues to stall and even fall, the pressure it puts on services is a factor for many. And we're seeing those with a few quid to rub together leave, but as long as those people leaving are straight, white males, or their families, they're being told "good riddance" regardless of the brain drain and loss of tax income.

Have they though about joining some sort of economic union, maybe one with like minded countries that share the same continent?
Show HN: Preq – Community powered detection of hidden reliability problems
by meehanto | 2025-07-28 17:11:59+00:00
Hey HN,

We’re excited to share preq ("preek"), an Apache‑2 licensed, community‑powered tool that scans your logs and configs to flag issues before they become incidents. It’s driven by Common Reliability Enumerations (CREs)—a growing library of community‑curated rules that describe real‑world failure patterns.

The project was inspired by the frustrations we experienced monitoring applications at leading companies:

* slow, manually incident investigations

* noisy telemetry and alerts

* missed warning signs that caused incidents

We believe engineering teams should be able to detect open source bugs, misconfigurations, and developer anti-patterns without hours of manual effort

We recently open-sourced preq which features:

* Auto‑updating rules: always stay in sync with the latest CREs from https://github.com/prequel-dev/cre

* Lightweight & cross‑platform: runs on Linux, macOS, Windows

* Native Kubernetes support: kubectl support via a Krew plugin

* Notifications: Slack integration and native kubectl support via a Krew plugin

* 100% open source: contributors welcome

We recently shipped v0.1.31 which adds:

* Embedded runbook expressions for guided remediation

* CLI parity tests & coverage reporting

* Improved auth timeout handling and bug fixes

* A slew of new unit tests across the engine, UX, and rule packages

* Welcoming many first‑time contributors: @samgaw, @amanycodes, @ramin, @kris‑gaudel, @Harsh9485

If this sounds useful, please leave us a on GitHub and drop any feedback or feature requests below. Huge thanks to everyone who’s helped shape this release—what should we tackle next?

Looking forward to your thoughts!

That is exactly how "ignoring" an user on Discord works. Their messages are still there and you have to click on it to have it uncollapsed, so that is kind of ironic of you to say, lmao. So yeah, there actually is a "nah I really want to see this tho" button.

You'd be surprised how much "secure" info is public somewhere else. Like when you're working on training materials for a certain engine that is considered "military secrets" based on the govt you're doing the work for, that takes literally weeks and weeks to get various design materials, that's considered public information for one of your nation's partners, and you can just download it from them instead of waiting for weeks.

> To support Blender’s mission of making 3D technology accessible to everyone

If accessibility is a priority for Blender, then they should absolutely be trying this. This isn’t going to be taking away the keyboard/mouse control that currently exists. The point is to give people, who (for whatever reason) can’t use a keyboard and mouse, a tool that they don’t currently have access to. There is also a large segment of the younger user base whose primary interface to computing is a tablet. This has the potential to open a whole new market of users for Blender.

Give them a little credit… I don’t think Blender is going to “downgrade” their existing workflows. For this tablet/pen project, who knows what kind of UI/UX they will have - it could be great. Plus, it is important for a project like Blender to have the freedom to experiment, otherwise you end up with a static ecosystem.

But, honestly, why wouldn’t you want Blender to make 3D work available to others who prefer to work with a different set of input devices? If that tool ends up as a “Blender Lite”, who cares? It may not be useful to you, but it will be useful to someone else. And maybe they find a new feature that will be useful to you in the process.

A writer wouldn't want an AI agent writing their book because the end product is their writing. Readers actually care about the words and prose. That's what they are paying for after all. Users of a software program meanwhile want it to work as promised, that's it. The syntax, language, design patterns used, how elegant the code is etc. are all irrelevant. If an AI agent can write "better" code (in terms of meeting that promise) than a human programmer than that is objectively the right way forward.

It's not perfectly bimodal. Some people are also more and less sensitive to testosterone. The average woman produces testosterone (I know, crazy) with some conditions like polycystic ovarian syndrome causing their testosterone production to go into overdrive.

Some sports actually do test for testosterone in order to determine eligibility (I believe volleyball?)

Also, interestingly enough, people that do estrogen injections end up with lower testosterone production. Estrogen also tends to (but not always!) block the effects of testosterone.

Hormones are weird and how individuals react to them is all over the board.

And example of that craziness is what the article refers to. People with Y chromosomes and uteruses. It's caused (AFAIK) because the fetus didn't respond to the hormones which cause the gonads to turn into male reproductive organs.

I know that there have been compatibility issues before, but it is worth mentioning that the current version of 11 LTSC was from november-ish last year so it is fairly up to date.

I am running it on 3 different gaming devices and have had zero issues with it, and I have it installed on my partner's gaming PC and he also has not had any issues with it.

also a "decade" I am not sure is true, the current version is 11 2024. Before that was 2021, 2019, 2016, 2015.

That being said, I would be very curious what games actually break.

Whilst you are at it...

https://github.com/openseadragon/openseadragon

A photo mosaic demands to have photos that are high resolution. You don't want to zoom in to find blurry jpegs, it just isn't right!

I have had great fun with OpenSeadragon in the past and now there is the VIPS image processing library for writing out a massive set of image tiles.

Hence it is possible to work with thumbnails and then render out the thing with OpenSeadragon and VIPS.

OpenSeadragon was amazing when it was a Microsoft demo a few decades ago, but time has moved on. I wonder what can be done with tilesets in HTML5 with picture tags or in SVG to present a infinitely zoomable montage.

I like your suggestion and the options for rotating and clipping images with SVG methods. I always confuse mask and clip, but, in SVG, much could be done.

For me, the starting point would be to do an SVG with thousands of images in it, to just watch my computer crash as I step up the resolution. Really I want to recreate OpenSeadragon in SVG...
