> The Reddit toxicity seems to taint young people into thinking that their employer is their enemy and that they have to approach the workplace like they're going into battle with evil managers.

They aren't that wrong however. Over the last two-three years alone we've seen waves of layoffs. Layoffs from FAANGs hit the headlines, but so many more happened without hitting the news.

And the thing is young people... They adapt.

They usually don't have the cultural baggage we older people have, so they often see things for what they truly are without any rose-tinted-glasses from past better times.

Their grandparents were able to get a fairly stable job at a company, stay there until retirement and grow a family. Their grandparents were able to switch jobs IF they wanted to. On the other hand, kids nowadays know they will likely be fired at some point, irrespective of their performance, and that they need to play the game for what it is.

Can you really blame them?

I came up with a similarly impressive compression scheme as a young teen, shortly after I started programming.

It was beautiful in its simplicity. Take 5 bytes, compute a 4-byte checksum, and just store the checksum. After all the chances of a checksum collision is miniscule.

When decompressing just iterate over all 5-byte values until you get the correct checksum.

The fantastic feature was of course that you could apply this recursively if you needed higher compression ratios.

Took me a good hour or so before I caught up with reality.

> We only need to look at states like California and their complete absence of voter id to realize where and for whom rampant election fraud takes place.

rampant election fraud isn't taking place at all.

When republicans want voter id passed they do it because they want to suppress votes. https://www.brennancenter.org/our-work/research-reports/impa...

There are ways to make voter ID work, ways to make them free and easy to obtain, but they aren't interested in any of that because they just want to stop "the wrong people" from voting.

If such a system proved that the answer to some decidable question was x, when the actual answer was y, then the system would prove a contradiction. If the system doesn’t prove a contradiction, then that situation doesn’t happen, so you can trust its answers to decidable questions.

If the only questions you accept as meaningful are the decidable ones, then you can trust its answers for all the questions you accept as meaningful and for which it has answers.

Also, “provable that nothing that exists can serve as such an oracle” seems pretty presumptive about what things can exist? Shouldn’t that be more like, “nothing which can be given in such-and-such way (essentially, no computable procedure) can be such an oracle”?

Why treat it as axiomatic that nothing that isn’t Turing-computable can exist? It seems unlikely that any finite physical object can compute any deterministic non-Turing-computable function (because it seems like state spaces for bounded regions of space have bounded dimension), but that’s not something that should be a priori, I think.

I guess it wouldn’t really be verifiable if such a machine did exist, because we would have no way to confirm that it never errs? Ah, wait, no, maybe using the MIP* = RE result, maybe we could in principle use that to test it?

btrfs is good, but it's far from perfect. RAID 5 and 6 don't exactly work, it can have problems at high snapshot counts, and there's lots of even recent reports of corruption and other kinds of filesystem damage.

It feels more user friendly than ZFS, but ZFS is much more feature complete. I used to use btrfs for all my personal stuff, but honestly ext4 is just easier.

Yeah, shoot down the satellites of an American company when you know:

1. That company provides satellite service for military units

2. That company's boss was recently a member of the US government, and is notably close friends with the US leadership

This will not go well. If a small dictatorial country does this, it would simply invite a rain of cruise missiles.

So I think SpaceX will likely continue as is.

Megaupload is a weird one. He hosted in it the USA, giving USA jurisidction. Also it's still going through the courts in New Zeland and USA and hasn't been proven hes guilty. And if I recall he did alledge he followed the DMCA, which if he ever is extradited might save him if it is in fact true.

Bronze-die pasta has an obvious and substantial textural difference from teflon-die pasta. The stickiness of the bronze requires more force from the extruder, but results in a rougher surface on the pasta, because it literally sticks to the die.

Bronze-cut pasta holds sauce much better, especially for thinner sauces. It also makes your pasta water more starchy, since it loses more material during cooking. These things seem very obvious to me via my observations as a cook who uses both from time to time (but mostly the bronze stuff).

Both properties can be very useful (the first to everyone, the second just to those who use their pasta water in the sauce step).

It's good to question our assumptions from time to time, but there's no reason to just deny something like this with absolutely nothing to back it up.

For sure! But just for reference, I'm on a mid-tier 2022 Dell Inspiron laptop: Ryzen 7 5825U with 64GB ram and 500GB SSD.

On it, I run Ubuntu 24.04 as my host, and my guest is Lubuntu with 16GB ram and 80GB ssd for my KVM.

I almost always have 2 instances of PHPstorm open in both Host and and Guest with multiple terminal tabs running various agentic tasks.

It’s important to put this in context.

Lp(a) is a largely distinct risk factor from “ordinary” cholesterol and cannot be changed by diet or exercise. Survey papers show practically no effective treatment (statins help all cause mortality in patients but do not lower lp(a)). There are two (iirc) ongoing trials for new, effective drugs. But those are not available yet and will probably be prohibitively expensive, going by the advertisements that the companies run.

So yeah, get an Lp(a) test once (it doesn’t vary too much over time) and reduce your other risk factors, but don’t put too much hope into an easy solution to this specific cause yet.

edit: found the two papers that were a good read:

Kamstrup, P. R. (2021). Lipoprotein(a) and Cardiovascular Disease. Clinical Chemistry, 67(1), 154–166. https://doi.org/10.1093/clinchem/hvaa247

yes they do. for one thing you do not make the rules around here; no one cares what you think counts as suitable grounds for arguing. For another, yes, authority has some merit. Doesn't make it fact, but certainly the prior we ought to assign for "medical authorities are correct" is quite high. Not certainty, but pretty confident, all else being equal.

edit: I see you added "I realize that we all go through life taking most things on faith, but that also means that you should not cling to the opinions of others as a substitute for thought."

Don't worry, nobody's doing that here. It's a question of weighting, not clinging. Maybe you mistook "this is not mainstream" to mean "this is definitely false because it's not mainstream"? It does not mean that. It is just helpful context for evaluating credibility.

It boils down to information loss in compaction driven by LLM's. Either you could carefully design tools that only give compacted output with high information density so models have to auto-compact or organize information only once in a while which eventually is going to be lossy.

Or you just give loads of information without thinking much about it, assuming models will have to do frequent compaction and memory organization and hope its not super lossy.

Working on a session recording app: https://scryspell.com

Currently it's meant to help devs fix UI and UX issues by seeing exactly what their users saw, including a log of the browser console and network traffic.

I say currently because it has preset analytics (charts for top entry page, top exit page, etc) but am working on letting users define their own trend and funnel charts. That will open it up to basic web/product analytics.

The goal is to be simple analytics + session recording w/ masking.

TechStack:

UI: React, ReactQuery, TypeScript

Backend: Java, SpringBoot, jOOQ, PostgreSQL

Using rrweb for the session recording.

So bizarre! It really shook my belief in Philips' competence at the time.

I mean, take a 100 minute movie, sliced into 1-second clips. 8kB is not even enough to store all possible orders you could put those clips in. I would hate to think so ill of any of my friends or colleagues to think that they could believe such an obvious fraud.

No.

There is no magic in buying/selling businesses, just put yourself in the shoes of the seller. JPM promise not to ever use that customer list you put in the data room should the deal fall over? How would you ever know if they did? You wouldn't trust a potential buyer and in practice companies do not. They'll put information in the data room, but not customer level details unless anonymized at which point you are back where you started as far as validating users.

So you are left with various legal/contractual solutions - things like "representations and warranties" (ask chatgpt about them), escrow agreements etc etc. And when it all goes to hell you go to court with your contract and attempt to get the money back. Such is life.

> the culture of not prioritizing correctness in computation

On the contrary, it is my impression the experienced Julia programmers, including those involved in JuliaLang/julia, take correctness seriously. More so than in many other PL communities.

> there are people working on traits/interfaces - but these are still peripheral projects and not part of the core mission to my knowledge

What exactly do you mean by "traits" or "interfaces"? Why do you think these "traits" would help with the issues that bug you?

The more likely outcome is going to be that these people will be left behind. If you came in with extreme views like say for things like DEI, would you be able to work that well with a female manager or a black coworker? If you came in with extreme views about lofty wage expectations or not working extra as a salaried employee, how likely are you to be hired or be put up for promotion? Keep in mind, we are not talking about reasonable takes, we are talking about extreme views that are formed solely through online spaces and not personal experiences.

It’s a good point. It IS hard to map the various “off-market RBACs” onto a unified model and this is part of the reason we delay that - and instead handle it with per-user syncs that include the q=“sharedWithMe” parameters.

As for intelligently - but probabilistically - determining confidentiality (if I read that correctly), that does sound pretty interesting in scenarios where metadata is just simply insufficient. Also tricky. Sounds like you thought about these problems pretty deeply.

Well, mainly the PSN hack that followed.

Repairing and recovering from that outage required the Playstation org at Sony to adopt a degree of professionalism wrt all tech dev and operations that started paying off remarkably quickly.

At the time a good number of people thought as a result of all this Sony would be pushed out of the console business.

> What incentives do people today have for keeping their identifications to themselves?

Not being liable for loans they didn't take out themselves, being the recipient of government benefits they are owed, etc. I'm sure you have heard of identity theft before, but it sounds like you haven't heard of why it's a bad thing. It's not just a privacy thing.

Nokia is the best case study of what not to do. In 2005 Nokia launched the 770 Internet Tablet. It was the groundwork for the modern smartphone. But the management did not allow it to have a GSM modem. So it was not a smartphone. Only after the iPhone Nokia launched the N900 but it was too late. Nokia did not believe in touch screen too.

As already pointed out that link is already gone, except for the IA. That's part of why it's "no loss" -- it's not actually lost.

Personally even if the IA didn't have a copy, I'd still say "marginal loss" and "inconvenient". imgur is just another in the line of image hosting sites that have come and gone. Much of what it hosts isn't actually high value, and isn't actually the sole copy.

Not sure what you're pining for with respect to "decentralization" -- we already have it, nothing stops someone from uploading an imgur image elsewhere, either the original uploader or someone downloading and reuploading somewhere. There are other image hosting sites. And yes, the internet is filled with dead URLs, privatized or deleted forums and discords and twitter accounts that host or previously hosted unique discussion or media, etc. etc. and any number of other minor tragedies. imgur totally dying would be among the least of them.

Cameron here @ Letta.

Letta now provides Anthropic's `memory` tool, enabling agents to dynamically manage their own memory architecture.

The memory tool is something I have wanted since before I started working at Letta, but never had the bandwidth to implement. Our researcher Kevin Lin ended up hacking it together in an evening, and it works swimmingly. But what does it enable?

Currently, Letta agents have a fixed memory architecture. A memory architecture is a set of memory blocks to track various types of information, such as communication guidelines, information about a user, company policies, how to use various tools, etc. Memory architecture can allow the agent to learn about nearly any type of information and persist it through its lifespan.

However, agents have not been able to modify this architecture themselves. They could modify what was INSIDE the blocks, such as including a note about how I like dogs when I mention it.

But the agent could not add a new block to track information that was unanticipated. For example, if the agent recognizes that it is struggling with understanding how to use tools, it either had to write tool use guidelines to some other block ill-suited for that purpose, or simply lose the information.

With the memory tool, the agent can decide to add a new block to accomodate this information. You can either ask it to add the block if you notice it struggling, or it may even choose to add the block itself.

The memory tool also allows "peeking" on blocks stored in something like a filesystem, such as /notes/letta to track the agent's notes on Letta. The agent can look at what is inside this memory without having to load it permanently into its context, which helps memory blocks resemble a filesystem.

I am extraordinarily proud of this tool and how quickly it came together. My sense is that this tool is one of the final building blocks needed to make Letta agents genuinely self-improving -- their "shape" is now under their own control, and they can now adapt much more readily to changing environments.

Very, very cool stuff.

I was looking into early letter forms and found this delightful book on sign-painting from 1878.

https://ia600606.us.archive.org/32/items/artofletteringsi00b...

One thing I found interesting is the terminology around types were not serif and san-serif but roman style and egyptian style. roman is still sort of used this way but I had never heard the term egyptian to refer to san serif letter forms. I wonder when we lost it.

AGPL or even GPL is fine. It's just a statement of intent: "artificial scarcity is bad, we want information to be free and those who take from the pile must add to it."

Realistically, open source licenses are legally powerless against corporations and governments, because they can hire more lawyers than you and rewrite the laws for themselves. We shouldn't play their game at all. The terms of open source licenses can be enforced socially. We can boycott, vote against, and shame violators. And we can be lenient towards other open source projects even if they use an incompatible license.

I have always read it as systemic. Which is why low carb diets seem to do wonders for a lot of people's cardiovascular systems, somewhat paradoxically. If you go really low carb (<20g / day), the first week or two you can lose a ton of weight, but much of it is water, which detractors point to as "well, you're not losing fat!" But, imagine what this does for inflammation. That is 7 pounds of fluid you are no longer carrying and pumping against. It's basically a gallon. The first round of keto I did, I lost a ton of weight the first month (~20 lbs), and my blood pressure plummeted to the point where I was dizzy all the time, and I had to supplement with salt and magnesium. I remember a study I read probably 15 years ago where they looked at cross-sections of arteries before and after starting a ketogenic diet, and there was significant reduction in inflammation after just a few weeks, IIRC. I just tried finding it on pubmed, but can't find the right incantation of search terms to dredge it up. There are countless studies like this.

I've been mostly on a keto diet since 2014, and it is probably the most important health choice I've ever made. At the time I worked in Neurology at a Children's hospital, and a keto diet is one of the treatment options for epilepsy. I talked with the clinical dietician at the time, and asked if these kids were having heart attacks in their 20s. On the contrary, much of the department was on the diet, or a low glycemic diet, as was much of the oncology dept. Obviously, this is an N of 1, and I'm not an MD, but every single aspect of my physiological and mental health has improved over the last 10+ years.

Hey - Reddit is included as a source because posts can contain firsthand accounts and independent analysis. The RSS feed we use from Reddit provides the post title and text. So to answer your question, when you see Reddit as a source we are using the aforementioned data, not what it links to.

About "common knowledge" sources - we validate all content for accuracy. When the LLM needs to add context that's missing from sources (e.g. historical background), we mark these as "common knowledge" since this generated content can't be validated against the original sources. You're right that your example isn't common knowledge at all, we'll work on adding actual sources for these claims too.

Thanks for trying it out!

Accurate virtual try on however is quite difficult, and users will quickly learn to distrust platforms that just generate something that"looks right".

You can prompt with a normal size 8 dress and "kim jungle un wearing a dress" and it will show you something that doesn't help you understand whether that dress would fit or not. You can ask for a tube dress and it will usually give him a big bust to hold it up. It's not useful for the purpose of visualing fit.

It will definitely be used for such just like image models already are for cheap tenu clothes, and our onions shopping experience will get worse.

Maybe this needs purpose built models like vibe-net or maybe you cab train a general purpose model to do it, but if they were spending the effort necessary to do so they'd be calling it out.

>Second, the people there don't "represent" anyone,

I think that's largely down to people not taking EU elections as seriously as national elections.

The ones elected by my country are always largely the most doldrum people from the main parties that aren't charismatic enough to win in national elections (The b-squad basically)

... and a handful of the kind of people that think windfarms generate wind and that we need to leave NATO.. even though we haven't joined NATO. The kind of people you vote to send to the EU so that you don't have to see them.

There was an election in 2024 https://en.wikipedia.org/wiki/2024_European_Parliament_elect...

For people unfamiliar with it https://elections.europa.eu/en/

The parliament is elected by people in each country, those elected them elect the commission. So a form of indirect elections.

It would be more effective if this was about the online saftey act. Ironically Imgur is probably already compliant with it (they already have moderation policies that go above what the OSA requires)

I think we should always be careful when we speak in absolutes. The conclusion from the article:

> This result suggests that oxidative stress may be a determinant of [C-reactive protein] levels and promote pro-atherosclerotic inflammatory processes at the earliest stages of [coronary heart disease] development.

I'm not saying the result is wrong, but I am saying "if you A you will not get B" is over-promising.

If you say you want to have a retro terminal where you can talk to ChatGPT, instead of telling you to use an LLM CLI in a terminal with a retro theme applied, LLMs will just build you a 500K-line terminal client from scratch uncritically. Even if you ask it to make architectural decisions, it will just riff off of your bad idea. And if you ask for critique, it will tell you bad ideas are good and good ideas are bad. We all have stories about arguing with LLMs until they tell us "Okay actually you're right, I was wrong because I think whatever my training data tells me to think."
