I cannot imagine anything worse than doing this!

I’ve not watched a video of people spelunking/potholing before. And now, having watched part of this, am unlikely to do so again.

I’ve experienced mild vertigo watching videos of, for example, cliff jumping, but I’ve never experienced such a visceral reaction to a video before.

Two minutes in where one of them has to take his helmet off because it is so tight, I felt such an overwhelming claustrophobia that I felt quite nauseous and had to stop watching. I’ve never felt anything like it watching a piece of video. Very bizarre.

Safety and utility can often be at odds. Sometimes safety concerns outweigh utility, sometimes they don't.

For instance, car accidents are an incredibly prevalent cause of death, and even though we had methods of transport before (and in many places, better methods even today), the convenience and ease that cars bring is largely deemed to outweigh the risks in most places (though note that there has been a constant drive toward reducing those risks, without giving up cars altogether).

A meaningful downside to something is an important perspective, but arguments about upsides are also always worth considering.

For the pans in particular, consider that alternative cooking methods may have required much more manual effort to perform or clean, or that they were more difficult to exercise well. There are tradeoffs around people cooking at home less if cooking is less convenient, up against the risks of harm from the things that make cooking convenient.

Not saying one side or the other is right, but the arguments are basically always worth at least considering, even in the face of really strong counter-arguments.

Very often a new idea comes to me, and I start actively working on it, but I often want to stop working on a project for the sake of a new idea, and so at one point I already have more than 20 unfinished projects.

Please share a way to do something about this or share your opinion.

Ukraine is at war, can conscripted men in Ruzzia refuse the conscription and leave teh country? No, since military service is mandatory

and I never said anything about Ukraine, comrade "What About" , Ukrainians are little soviets , not giant soviets like the Moscowites so I will not see me praise them, I just do not want mr Putin make the USSR great again and bring back the genocides.

So , since I did not claim Ukraine is a paradise not show me why the USSR and NK paradises do not let people out, not let people communicate with their relatives outside and tell them how perfect, nice or good enough the paradise is.

I bet you will respond with "What About" or some other pre-written text from your soviet book or propaganda.

I disagree. It strongly detracts from the GP’s claim.

If we see huge variation in intelligence scores intra group, that strongly suggests that there are social/cultural/environmental factors in play driving a large part of this.

It may be true that some racial backgrounds offer an advantage; but there is no evidence to suggest that this advantage is materially large relative to many of the social structural drivers that are obvious.

The subtext of the claim is not that a statistically significant effect exists. It’s that there is a big important difference in intelligence across races intrinsically derived from genetics. And there’s no compelling evidence to support that.

> Cheese is worst thing ever for saturated fat, which clogs the arteries, gives you diabetes and sends you to hospital for some bypass surgery. Besides, what is natural about consuming dairy? The bull gets jerked off, the cow gets artificially inseminated, the baby gets eaten and the milk for the baby gets stolen. That is just plain weird. Technically everything is natural if you want to see it that way.

At least no almonds got jerked off in the process.

People have been eating cheese and yogurt for ten thousand years. It's not weird - trying to make it weird is weird!

I'm not trying to be mean, but I am giving unsolicited feedback - trying that angle to convince people to not eat cheese is only gonna work on your choir. Everyone else is gonna wonder why tf you're thinking of bulls being jerked off, and then go right back to enjoying cheese. Certain varieties have excellent macros and price ratios so the health angle doesn't really work either.

Nobody's asking but personally I think the best path for vegans to take is the Impossible meat angle. I know folks that prefer it now that were 16oz steak guys. It's healthier and yummy and priced just about the same as a normal burger. Whip up the same for cheese and you're in business. Right now all the cheese alternatives are kinda bad and also give me the worst farts lol.

Thank you for doing it ! What was the motivation behind it/when did you start building it ?

I never built anything with it but reading through the source code got me to learn so much about programming. I probably spent more time copying stuff from Irrlicht/Ogre3D/ODE (although I never managed to grok that one) than anything else in high school.

I saw this with a family member. In their 60s, they started getting stuck on small worries and always assumed the worst. At first it just seemed like anxiety, but over time their memory and focus started slipping too. It was like their mind got stuck in a loop.

What helped the most wasn’t medicine. It was little things, like going for walks together or having simple conversations. Just giving the brain something new to pay attention to seemed to make a real difference.

It's often quite easy to distinguish LLM-generated low-effort slop and it's far easier to point to the established policy than to explain why the PR is a complete garbage. On Github it's even easier to detect by inspecting the author's contribution history (and if it's private it's an automatic red flag).

Of course, if someone has used LLM during development as a helper tool and done the necessary work of properly reviewing and fixing the generated code, then it can be borderline impossible to detect, but such PRs are much less problematic.

I'd much rather eat a cake that has the texture of a cake rather than some food science abomination. It's corporations that have taught you to desire the wrong definition of a cake.

Grandmas should not be cooking cakes from boxes of cake dust, they should be using flour and producing a cake that tastes like it was cooked by a grandma. That is the natural order of things.

Being made with traditional methods and ingredients, is per se a virtue. If grandma cooks fries you wouldn't complain that McDonalds does it better. Home cooking is great because it was cooked at home using the limited equipment and ingredients of a home kitchen that give it a natural and traditional taste.

He didn't step away. He made a post where he "stepped down" as the project lead and instead got replaced by a "GrapheneOS Foundation director", of which there are 3 including him.

That post has been deleted.

As far as I can tell, nothing has changed other than obscuring the leadership of the project a tiny bit. strcat is still active here in the comments.

My intuition of this problem is much simpler — assuming there’s some rough hierarchy of concepts, you can guesstimate how many concepts can exist in a 12,000-d space by taking the combinatorial of the number of dimensions. In that world, each concept is mutually orthgonal with every other concept in at least some dimension. While that doesn’t mean their cosine distance is large, it does mean you’re guaranteed a function that can linearly separate the two concepts.

It means you get 12,000! (Factorial) concepts in the limit case, more than enough room to fit a taxonomy

> What do you think of C and C++ coming with extensive guides for best practices and what features to not use?

I feel that this is a disingenuous point and that you know better than this.

For example, the poster child of C++'s "don't use this feature" cliche are exceptions, and it's origins are primarily in Google's C++ stye guide.

https://google.github.io/styleguide/cppguide.html#Exceptions

If you cross-reference your claims with what Google's rationale was, you will be forced to admit your remark misrepresents the whole point.

You do not need to read too far to realize Google's point is that they have a huge stack of legacy code that is not exception-safe and not expected to be refactored, and introducing exceptions would lead their legacy code to break in ways that is not easy to remediate.

So Google had to make a call, and they decided to add the caveat that if your code is expected to be invoked by exception-free code, it should not throw exceptions.

Taken from the guide:

> Because most existing C++ code at Google is not prepared to deal with exceptions, it is comparatively difficult to adopt new code that generates exceptions.

I wonder why you left this bit out.

If this is how you try to get D to shine, then you should know why it isn't.

Self raising flour was invented by a British baker, Henry Jones, in an attempt to make better bread for sailors. We still have it in the UK and I never trust it, always adding baking powder anyway to cakes. We have plain flour for pastry and sauces and then bread flour (higher gluten) for bread. I always have three flours in my cupboard.

My understanding is that it also affects RAG ("grounding" in Google terminology):

> [...] and for grounding (providing content from the Google Search index to the model at prompt time to improve factuality and relevancy) in Gemini Apps and Grounding with Google Search on Vertex AI.

So they seem to be blocking both training and RAG while still allowing search engine indexing.

Meanwhile, here in Canada I've never seen "sticks of butter", only the large bricks. They're the same size as American ones, and labeled as 454g, but I only recently found out that in some places in the US, they cut them in fours. Before that, the phrase didn't mean anything to me, and I thought it referred to throwing the whole brick in. The smaller 250g packages also exist, but they're rare.

I can't guarantee that the sticks don't exist anywhere, but I've lived in several cities all over the country and I've never spotted anything like that

I do like the idea, but streaming is so incredibly convenient. I used to use Plex as my sidecar where I put the stuff that wasn't on Spotify. Now I use Apple Music with iCloud Music Library which lets me upload a hundred thousand songs. Everything I buy on Bandcamp goes there and this lets me put that in the same playlist as anything else on Apple Music and stream it to any device.

Fun post! I like reading blog posts like this.

I did wonder about one thing:

> The first measure I tracked was a ‘Colourfulness score’. This measures how intense and varied the colours are in a poster. Higher values mean the image contains more saturated and diverse colours, while lower values indicate a more muted or monochrome palette.

As the description suggests, it seems to me these are actually two things: one is how saturated the colors are and one is how diverse they are. In other words one is how much color there is and one is how many colors there are. The examples given for each color later on are ones where a single color predominates, but it's not clear from the article how common this pattern is.

Personally I'm intrigued by posters that use a wider palette. Subjectively it feels to me that movie posters have moved towards a minimalist design over the past 10-20 years (as have book covers), making single colors more central, but I'm not sure whether that hunch would be borne out by data.
by yorwba | 2025-09-15 06:19:42+00:00
I think the author is too focused on the case where all vectors are orthogonal and as a consequence overestimates the amount of error that would be acceptable in practice. The challenge isn't keeping orthogonal vectors almost orthogonal, but keeping the distance ordering between vectors that are far from orthogonal. Even much smaller values of epsilon can give you trouble there.

So the claim that "This research suggests that current embedding dimensions (1,000-20,000) provide more than adequate capacity for representing human knowledge and reasoning." is way too optimistic in my opinion.

I don‘t think negativity necessarily has something to do with trauma. Negativity bias is very widespread, regardless of previous trauma. Basically everybody flies at negativity.

Bad and shocking headlines click way better than positive ones, negative feedback is occupying our attention more than positive feedback, we perceive losses way more important than gains, we perceive losses as way more impactful than gains of the same degree, etc.

I am 100% sure trauma can and does affect the negativity aspect of our thinking in a big way. But I do not think that negative thinking overtopping positive thinking is limited to trauma sufferers

Yes. Anyone can be gotten with the right bait. Most people are never targeted and there's a lot of things that mitigate spray-n-pray attacks, but when it comes down to it, human cognition just has some fundamental exploitable weaknesses. It doesn't really have anything to do with intelligence.

For example, we're insanely good at pattern matching, but the flip side to that is we're not effective at spotting the rare subtle difference.

The way I use AI for coding is that I type in the business logic in english and have AI take over the typing. Sometimes I fill in a skeleton and have AI write the boring stuff. But I agree with the author - outsource labor never knowledge. I found AI actually made me a better programmer (judging by feels not metrics) because I know have to explain my thinking which clears up the mud in my head. After which writing the code is leg work better outsourced.

https://en.wikipedia.org/wiki/Leaky_gut_syndrome Thank you, I'd not read it was a myth before and had confused it with another condition 'worsening allergy symptoms due to the effects of alcohol'.

Sorry, I couldn't find a good link to describe the effect but did see numerous websites mentioning that alcohol can worsen allergy symptoms.

My allergist informed me that alcohol dilates the blood vessels allowing more allergens to pass thru. My anecdotal evidence is that I do seem to suffer from more food allergies when I drink alcohol. Foods that I have a mild allergy to become seem to be more problematic when I drink.

We have to distinguish delivery and discovery. Any competing video platform will have a very skewed selection of content at the start, biased towards stuff YouTube doesn't want to show its users, and in most cases, with good reason (i.e, stuff the users wouldn't want to see). Any kind of popularity-on-the-platform based filtrering will also not work, due to this skew.

Russia is already very large and sparsely populated. They don't want more territory. What they want is to not be surrounded by enemies, which is why the current war is happening: basically try to force a regime change after the USA did their regime change a few years ago.

USA could not defeat afghanistan so I doubt it intimidates anyone really… if we are talking conventional warfare.

Anyway despite all of Trump's bullshit talking points, USA will do as always militarily, because it's convenient to them that EU doesn't become independent.

I am sick of people raising this developer's mental issues. This is 2025, we should be sympathetic and encouranging to any human being struggling with mental issues, helping them get through or at least not trip them or sideline them. GrapheneOS is undeniably a project of great value, if you don't like something about it's development raise it and stop there as you would do with any project. Stop the "Graphene doesn't have X feature but the lead dev is nuts so I don't touch it" meme.

I have to fully agree. They have a discussion on their GitHub [0] about tabs/identation stating that the design goal is to have a non-configurable formatter.

I get the idea behind having a streamlined formatting style, but I’m really not a fan of denying users the flexibility to adjust it to their needs. Consistency across projects is nice, yet forcing everyone into a single indentation style feels unnecessarily rigid. A little configurability would go a long way :)

This is just the new normal.

They have been doing it since at least 2019 when they started the "fake news" inquisition where they were victims, investigators, prosecutors, judges and executioners in a case involving wildcard crimes against themselves covering the entire brazilian territory. A literal kangaroo court.

That's not enough, they went even further. They perpetrated a silent coup. These unelected judge-kings have usurped so much power they have essentially taken over the legislative and executive branches of government. They openly legislate despite not a single brazilian having voted for them. They are so brazen as to raise taxes. Politicians can impeach them but they don't dare to do it because they are the ones who judge politicians for corruption.

The amount of mental gymnastics you're doing here is impressive.

Your current iteration is trying to differentiate between insulting a person (ie. the ugly wife) and insulting people in aggregate. And arguing that ideas about an aggregate is not insulting a person, and therefore, the aggregate cannot be insulted or offended.

Then you jump to a logical fallacy that if you challenging some ideas is offensive, then challenging all ideas is offensive.

You do realize that co-workers discussing whether we should use AWS or Azure as our cloud provider could be a rich debate on the topic. But is highly unlikely to result in someone becoming offended and evenly less likely to result in some form of violence.

But this is altogether different from other kinds of ideas. We can discuss ideas along the same topic and at some point we transition from rational debate to offense. We can start with the idea that people with blue eyes are fundamentally different than those with other eye colors. That's not too offensive. Let's take it further, people with blue eyes are inferior to all other eye colors. This might offends some people. What about, people with blue eye color are so inferior that we should expel them to "blue-eyed people island". How about, people with blue eyes are so inferior that they would be better off as slaves for people of other eye colors.

What if I went on a tour across the country to debate blue-eyed people on the topic. Did I incite any violence? Did my ideas offend any aggregate? Would you be surprised if my ideas resulted in violence against me?

If you replace "blue eyes" with other things, you can see the number and ferocity of the aggregate changes depending on the topic at hand. Your ideas are so provably contradictory to the ways of the world that I don't understand how this isn't obvious to you. Wars have been waged over the idea that one religion is superior/inferior to another. Galileo was imprisoned for his idea that planets revolved around the sun. I can go on and on.

This is honestly the main reason I prefer Playwright to Cypress. Playwright leans heavily into using POs, while for some reason Cypress doesn't.

So in almost every project the Cypress tests are a procedural mess, while the Playwright tests are mostly well structured.

I know that Cypress has other patterns for dealing with this but they never seem to get applied.

Mindify Cortex — AI-powered workspace for product teams and engineers

We’ve been working on Mindify Cortex, an AI-powered workspace that helps product teams and founders focus on decisions instead of busywork.

Cortex combines an agent layer with your workflow so you can:

- Summarize and query across docs, chats, and data with the help of an AI workflow and agent. - Automate repetitive workflows (status reports, docs, syncs) and automate the knowledge collection with our radar feature. - Collaborate with AI agents that stay aware of your project context.

Why we built it:

- As founders, we kept drowning in docs, updates, and context-switching. Tools either gave us raw AI (ChatGPT tabs) or rigid project software. We wanted something in between: flexible like an agent, structured like a workspace.

Where it’s at:

- Public beta launched today. - Core features live: doc ingestion, agent queries, workflow templates. - Still rough around the edges — we’re eager for feedback.

Try it here: cortex.mindifyai.dev

We’d love to hear from you:

- What use-cases resonate (or don’t)? - Where would you want an AI workspace to plug in? - What would make you trust this for actual work?

Thanks for reading, and thanks in advance for feedback (critical or otherwise). We’ll be around in the comments all day.

— Mark & team at Mindify AI

I've made loads and it is trivial. You literally just follow the recipe.

Bread is a lot more difficult due to kneeding and shaping which are skills that must be honed.

Cakes, on the other hand, are just mixing and pouring which any idiot can do. The only real variable is the flour so some recipes might work better in your region than others, but cakes are still much more forgiving than bread (flour is more than half of bread by weight, but often less than a third of a cake).

This raises questions.

For example, modern x86 architectures still readily out-perform ARM64 in performance-engineered contexts. I don’t think that is controversial. There are a lot of ways to explain it e.g. x86 is significantly more efficient in some other unrelated areas, x86 code is tacitly designed to minimize the performance impact of TSO, or the Apple Silicon implementations nerf the TSO because it isn’t worth the cost to optimize a compatibility shim. TSO must have some value in some contexts, it wasn’t chosen arbitrarily.

Apple Silicon is also an unconventional implementation of ARM64, so I wonder the extent to which this applies to any other ARM64 implementation. I’d like to see more thorough and diverse data. It feels like there are confounding factors.

I think it is great that this is being studied, I’m just not sure it is actionable without much better and more rigorous measurement across unrelated silicon microarchitectures.

I would interpret this as similar to being able to take paper napkins or straws at a restaurant. You may be welcome to take napkins, but if you go around taking all the napkins from every dispenser you'll likely be kicked out and possibly they'll start keeping the napkins behind the counter in the future. Similarly if people start treating "you can contribute AI code to LLVM" as "feel free to submit nonsense you don't understand", I would not be surprised to see LLVM change its stance on the matter.
