> But at the end of your life, total it all up. You should have produced more than you consumed. That’s what it means to be a good person.

Summing up one's life in terms of "production" and "consumption" is such a broken way of looking at things.

I will be kind to people. I will be patient with them. I will try to help them. I'll try to make the world a better place in all the little ways I can. How much or how little I "produce" has no bearing on whether my life will be weighed as good or bad.

And since we're quoting incredible TV shows...

"The success or failure of your deeds does not add up to the sum of your life. Your spirit cannot be weighed. Judge yourself by the intentions of your actions, and by the strength with which you faced the challenges that have stood in your way. The Universe is vast and we are so small. There is really only one thing we can ever truly control... whether we are good or evil." - Oma Desala, Stargate SG-1

There's around 50M rooms, and the dataset is back to 2014.

However, much of the room is taken up by the Synapse DB schema being particularly denormalised (prioritising performance over disk footprint) - especially caching snapshots of historical key/value state for rooms, which currently takes up ~65x more space than then actual underlying dataset. Ironically, we're looking into that currently, but not fast enough to speed up this DB rebuild.

People are already taking to the streets there over immigration. I've thought about submitting that story but it's hard to find a source that I'd feel comfortable posting that also covers enough of what's going on to be worthwhile.

(The optics are incredible, though. The protesters are able to show footage of women being arrested ostensibly for putting up English and even UK flags, in the UK, and crowds being pushed around by police phalanxes in riot gear; meanwhile counter-protesters call them "fascists" and ramble about domestic violence charges.)

I tell you you’re idiots.

You will never live in a world where everyone minds their own business. Never. And the government is not the only eavesdropper. Idiot. The commercial market that sells to the gov or anyone else like a fish market. Those new era private interest groups consuming your data, whether Cambridge Analytics or Mossad or whoever want a stake in your ass.

A culture of vigilance, competence, and distributed sensibilities are your only hope.

Stop acting like a lame duck and see your life of obeyed self privilege as the lie.

No one is claiming it is storing electricity. I think people who use imperial (BTU) units for heat but SI units for electric power some times get confused by what power really is and what a battery is.

Something that stores _energy_ is a battery. Not necessarily electric energy. You can absolutely have a battery with mechanical energy (wound up springs), a battery with kinetic energy (a weight in a shaft) a battery with nuclear energy (Thermal reactor in a satellite), a battery with thermal energy (silo full of very hot sand) or a battery with chemical energy such as a Li-ion battery.

This stores 100 MWh heat energy, so it is a battery.

From wikipedia:

> Energy storage is the capture of energy produced at one time for use at a later time to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery.

Amazingly, I think you’re right, but not for (negative) the reasons you state.

I see the 3D printing scene a remix culture where you’re supposed to try new things. If you want something to work exactly for your situation, you might have to do a little work yourself.

In this case, here we have an idea of making new typeballs for IBM typewriters. Here is one post where someone is playing with the idea. At the top of the page, there is a link to a GitHub page for you to adapt it as you see fit.

But then there’s also a link to a new page: https://selectricrescue.org/ where someone makes many more varieties, also with code for you to try yourself.

I see 3d printing much like the world of early open source coding. Sometimes you get a completed project that works out of the box. But often, you’ll have to tinker and adapt it to your exact hardware. Once a new 3d model is shown to be viable, it can be mixed and matched to make something new!

I used to do Java about a decade ago and because it was in a corporate environment, add about 5+ years of using outdated Java on top of that. Web applications are what I do, have been doing for 25 years and I use Ruby/Rails now.

I do want to do something meaningful/professional with Go but haven't gotten around to trying it out. I also sort of feel most programming language additions aren't game changers these days. Much like smart phones, the killer feature days are over, small incremental additions are nice.

The killer feature to me is using AI for tedious tasks or syntax I don't remember and in that respect I do wonder if Java would be easier to deal with than what I remember.

Interesting!

I've never thought alcohol tastes like bleach, though in some I can now certainly get a taste of "ethanol", same with the charcoal coffee thing -- many flavours I've found in coffee, but never charcoal.

I wouldn't be surprised if we all have some kind of genetic marker/mutation (I'm not a biologist, sorry!) that impacts the way we taste certain foods.

There's a longer paragraph on that topic in Section 8. We also previously built an LLVM back-end using that approach [1]. While that approach leads to even faster compilation, run-time performance is much worse (2.5x slower than LLVM -O0) due to more-or-less impossible register allocation for the snippets.

Two of them, giving us stereo vision. We are provided visual cues that encode depth. The ideal world model would at least have this. A world model for a video game on a monitor might be able to get away with no depth information, but a) normal engines do have this information and it would make sense to provide as much data to a general model as possible, and b) the models wouldn't work on AR/VR. Training on stereo captures seems like a win all around.
Ask HN: A memory challenge/nerd cry for help finding back a blog posted on HN
by KolmogorovComp | 2025-09-03 12:34:35+00:00
I've been looking to find back a blog post I've read here in the beginning of 2025 (most likely before 2025/04/21), that I thought I had bookmarked to read later.

I don't have much information besides visual clues: - minimal blog hosted a small domain - beige-ish background - a font close to times new roman (unusual for a blog) - each paragraph has an Initial (larger letter) - the article contained code blocks(?)

While its content is most likely not world-changing, my inability to find it back has been driving me crazy, so asking the collective hive mind for their help. Any lead is appreciated

We're building an AI-native assistant designed specifically for Unity developers — not just to generate code, but to deeply understand the entire project: assets, structure, scripts, and logic.

We’re giving away 3,000 free credits for early adopters, no credit card required.

Would love your feedback — especially from devs working on complex Unity pipelines or debugging large legacy projects.

I tried some TTS models a while ago, but I noticed that none of them allowed to put markup statements in the text. For example, it would be nice to do something like:

Hey look! [enthusiastic] Should we tell the others? Maybe not ... [giggles]

etc.

In fact, I think this kind of thing is absolutely necessary if you want to use this to replace a voice actor.

I think this actually points at a different problem, a problem with LLM users, but only to the extent that it's a problem with people with respect to any questions they have to ask any source they consider an authority at all. No LLM, nor any other source on the Internet, nor any other source off the Internet, can give you reliable dosage guidelines for copper peptides because this is information that is not known to humans. There is some answer to the question of what response you might expect and how that varies by dose, but without the clinical trials ever having been conducted, it's not an answer anyone actually has. Marketing and popular misconceptions about AI lead to people expecting it to be able to conjure facts out of thin air, perhaps reasoning from first principles using its highly honed model of human physiology.

It's an uncomfortable position to be in trying to biohack your way to a more youthful appearance using treatments that have never been studied in human trials, but that's the reality you're facing. Whatever guidelines you manage to find, whether from the telehealth clinic directly, or from a language model that read the Internet and ingested that along with maybe a few other sources, are generally extrapolated from early rodent studies and all that's being extrapolated is an allometric scaling from rat body to human body of the dosage the researchers actually gave to the rats. What effect that actually had, and how that may or may not translate to humans, is not usually a part of the consideration. To at least some extent, it can't be if the compound was never trialed on humans.

You're basically just going with scale up a dosage to human sized that at least didn't kill the rats. Take that and it probably won't kill you. What it might actually do can't be answered, not by doctors, not by an LLM, not by Wikipedia, not by anecdotes from past biohackers who tried it on themselves. This is not a failure of information retrieval or compression. You're just asking for information that is not known to anyone, so no one can give it to you.

If there's a problem here specific to LLMs, it's that they'll generally give you an answer anyway and will not in any way quantify the extent to which it is probably bullshit and why.

Despite the noted slide, it feels accurate. I, for one, would not want to move back to EU despite some QoL notables. At this time, it is still hard to find a better spot for a random nobody ( when you have money and/or power, 'where you can live well' calculus changes ).

>The beautiful reveal is that this addition and composition of linear transformations behave almost the same as addition and multiplication of real numbers.

This is only beautiful if you already understand monoids, magmas and abelian half groups (semigroups) and how they form groups. Also, we do not talk of linear transformations, we talk of group homomorphisms.

I don't know about anyone else, but I was taught linear algebra this way in the first semester and it felt like stumbling in a dark room and then having the lights turned on in the last week as if that was going to be payback for all the toe stubbing.

Yeah, the parent's implication is just wrong:

> As previously stated, this is only an issue for non-practiced typers. With practice, it no longer feels like stretching. It just becomes muscle memory.

Becoming a good typist doesn't magically change your pinkie from being the weakest finger on your hand to the strongest. That's basic anatomy. And, specifically if you are a good typist, then your neutral hand position will absolutely involve stretching your pinkie to hit enter/backspace/shift - they're exactly wrong with their assertion.

I'm vaguely aware of the Kinesis Advantage - it looks like a pretty solid ergonomic keyboard (although it may not be for me because it's not a split keyboard and my shoulders are pretty wide). Does the software do QMK stuff like mod-tap?

It's a long scroll down to the bit that responds to the title:

> Travelling under 24 hours of daylight definitely changes you. At first it feels like a gift; endless time to explore, hike, fish, and wander without the urgency of sunset. But then sleep deprivation creeps in and your sense of time warps. Meals happen whenever you remember them, not because of hunger.

> The mental effect is harder to pin down. A constant day gives you freedom, but also restlessness. I found myself craving darkness, craving the reset of night.

I had a few weeks cycling and travelling around Iceland in the middle of summer. It was great. I didn't really experience any downsides at all.

One of the Teletypes I used to work on had an eccentric-driven Wiffletree to position the typebox. This was necessary because of it's high speed[0] to decode the ASCII character set (it wasn't a Baudot machine). The selector cam at the end of the machine would do the serial-to-parallel conversion, then clutches would rotate the eccentrics powering the wiffletree to select the character.

If you look at the ASCII chart [1] you can select a character via binary tree - the Wiffletree being a mechanical equivalent.

I don’t know.

I had noticed the Norway interconnect was running at 0 MW, and I was trying different sites to see if it was the data feed.

It wasn’t, it seems Norway NO2 area has 50% water levels in its hydro dams, the rest seem OK but NO2 region is the one which exports power to UK, Germany, and Denmark.

The little animations of power moving along lines are very cool.

Thanks for all the positive vibes & hugops folks :D

Fwiw, the DB isn't corrupted - the database 2ndary dropped its RAID array on having new disks added (the hw raid controller incorrectly added them into the array, breaking it)... and a few hours later we lost the primary db too. The outage is caused by the time taken to restore & rebuild a 55T db from nightly snapshot.

In terms of lack of documentation for running Element Call: i published a tutorial & video run-through myself back in November: https://element.io/blog/experimenting-with-matrix-2-0-using-... and https://github.com/element-hq/element-docker-demo and https://youtu.be/6iMi5BiQcoI. Or you could just run it via Element Server Suite: https://element.io/server-suite/community

In terms of "Element X has a 10th of the functionality of classic Element" - with respect, this is bullshit. The only features folks complain about missing are Threads & Spaces, both of which are have implementations behind feature flags and will land shortly. In all other respects Element X is a wild improvement over classic Element.

Fwiw, there's another HN thread on this over at https://news.ycombinator.com/item?id=45107696

Yeah every time I see one of these articles posted on HN I know I'll see a bunch of comments like "well here's how I use claude code: I keep it on a tight leash and have short feedback loops, so that I'm still the driver, and have markdown files that explain the style I'm going for...". Which is fine lol but I'm tired of seeing the exact same conversations.

It's exhausting to hear about AI all the time but it's fun to watch history happen. In a decade we'll look back at all these convos and remember how wild of a time it was to be a programmer.

I've only given talks to small audiences but they were very well-received. I often focus on humour, partially because I don't really have the background to deep-dive technical material hard enough for that to be interesting in-and-of-itself (maybe this is imposter syndrome).

It is very important though. It's very easy to lose an audience, and the truth is a lot of the speakers before you will likely range from slightly boring to extremely boring. The audience can be primed to totally clock out if you don't grab them immediately and keep them for the whole thing.

If you have a Debian or Ubuntu system available, installing the `slapd` package (OpenLDAP) would be sufficient to get something on localhost or ldapi:///. RH-based systems have openldap* packages.

You don't really have to do much more than that for the purpose of testing this (no creating of accounts, groups, sub-trees, etc).

Perhaps at most go to the stanza/paragraph that defines "olcDbIndex" values, add a new one, and see if a new index file is created in "olcDbDirectory" (often /var/lib/ldap):

> The raw mathematics isn't the hardest; most of this is settled by the end of the second year of undergraduate physics—things like Taylor series, ODEs, PDEs, special functions, a bit of linear algebra (no proofs needed, just use the results); perhaps complex analysis which leads to Fourier transforms and all. Maybe a treatment of tensors.

It sounds like the OP is saying you could tackle the article if you just know a little high school calculus and trig, and you're here saying that you need years of post-secondary mathematical education. I think you're making his case that he's dramatically simplified understanding how to compute these things for someone who doesn't have a post-secondary education.

> There is rarely a stable definition of "work". Is it RPS? Request cost can vary even throughout the day. Is it instructions? Same, the typical IPC can vary.

I think this is probably one of the most important points... similarly, is this public facing work dealing with any kind of user request, or is it simply crunching numbers/data to build an AI model from a stable backlog/queue?

My take has always been with modern multi-core, hyper-threaded CPUs that are burstable is to consider ~60% a "loaded" server. That should have work split if it's that way for any significant portion of a day. Mostly dealing with user-facing services. So bursts and higher traffic portions of the day are dramatically different from lower utilization portions of the day.

A decade ago, this lead to a lot of work for cloud provisioning on demand for the heavier load times. Today it's a bit more complicated when you have servers with 100+ cores as an option for under $30k (guestimate based on $10k CPU price). Today, I'd lean to over-provisioning dedicated server hardware and supplement with cloud services (and/or self-cloud-like on K8s) as pragmatically as reasonable... depending on the services of course. I'm not currently in a position where I have this level of input though.

Just looking at how, as an example, StackOverflow scaled in the early days is even more possible/prudent today to a much larger extent... You can go a very long way with a half/full rack and a 10gb uplink in a colo data center or two.

In any case, for me... >= 65% CPU load for >= 30m/day means it's at 100% effective utilization, and needs expansion relatively soon. Just my own take.
