I think it depends a lot on your finances though. If you come from a rich family and have parental support by all means it is amazing to travel young. But if your travel budget is coming out of your downpayment on your house that could easily be the difference between buying before house prices got out of control or not. For example if you could have bought in 2013 without travel and it takes you till 2015 to save up a 2013 downpayment but in 2015 house prices have gone up and your downpayment needs to be larger and it takes more time, etc.

I would like to have some meaningful part-time work when I retire.

Sure, I garden, landscape, play with my tractor, spend more time playing guitar than any other hobby and go to the gym 3 times a week, but I would still want some sort of additional "purpose" to keep me engaged with society (I'm not exactly an introvert but left purely to my own devices I tend to entertain myself pretty solitarily).

>Adding soft deletes to a legacy app

As an aside, I've never found this to be worth it since you have to change too much and re-test everything for minimal user benefit and time savings. The effort is way worse if the code is not great in the first place. It can be a great decision to make before everything is written.

Maybe it's worth it for files which are hard to reproduce, but you can also rely on DB backups to get those back. If people are regularly deleting things they're not supposed to, you're better off removing the user-facing delete actions, limiting the action to specific users, etc.

This looks very interesting purely because I can just about see from the very fast gif on the README that it has tasks in there, how much of a first class citizen they are of the app could be really important. It blows my mind that both Slack and Notion have such half-arsed task implementations - every time I need to introduce better, asynchronous task assignments at work I get pushback over "people won't use yet another app" - and sure enough, getting people to assign me something rather than @ notifying me while I'm nose deep in code of something that needs doing in a few days time has been impossible. A single app that lets a team manage work without constant interruptions would be the dream.

They all default to ISO sizes for me.

If I format the page size, Libreoffice does offer "Letter" and "Legal". GIMP shows them as "US Letter" and "US Legal" but again they're not the default.

It wouldn't surprise me if most non-US users hadn't seen them at all, and certainly not that they don't realise the US uses a different size.
Note investor who's blowing up a deal over a board seat
by 3dpodium | 2025-04-24 13:52:30+00:00
We just signed a term sheet with a top-tier VC for our first priced round, and their only board requirement is a three-person board. So far, we’ve raised money via convertible notes from several investors—one of whom is ultra-wealthy, and has a rather large ego. He isn’t investing in this round, but now he’s demanding a board seat. He’s threatened to call his note or sue us (and the new VC) if we don’t give it to him. As a result, our lead investor is threatening to walk away—they absolutely don’t want him on the board or even a board observer.I spoke with other founders whom this guy has invested in, and he's done this to several of his portfolio companies, so I know he's not bluffing.

Any advice on how to handle this?

There's a difference between trying your damndest during working hours, and hustle nonsense. In my experience, employers see time spent on site as a measure of success more than how productive you are during your regular workday.

So I read that to mean, don't kill yourself working unpaid overtime. You can still do a great job, working established working hours. I agree with that 100%. While I'm at work, I'm at work. But the moment that the day is over, work does not exist and will not exist.

When I last bought a car 5 years ago, the used car marked for EVs was very small and EVs were very expensive. Since then, they became much cheaper, there are a lot of new models and a lot of used cars on the market.

I'm not planning to buy a new car though, as mine is only 8 years old and still working fine. I'll check again when repairs start to get more expensive, maybe in a few years.

> Are US letter sizes what people use instead of A4 in a workplace for documents and such (seems confusing if so)

Yes, it is just our standard like A4 is yours. When you pull a paper out of the pack it is A4 when we pull it out it is ANSI A, commonly known a US Letter size. Instead of 8.27”x11.69”, we use 8.5”x11”. We also commonly use US Legal size, which is 8.5”x14”. Slightly longer and can fit in the same envelope.

> do printers sold in the US default to US letter sizes when printing?

Yes. However all of our printers can do all sizes since our paper is slightly larger, while an A4 specific printer couldn’t print a US letter.

Finding those companies is hard, especially when there's an obvious winner. Hell, I'd have joined facebook (not in hindsight, though) in the early 2000s because the specific challenges they were facing would have been novel. That being said, I'd likely feel terrible for what FB became had I did.

I visited the FB campus ~2015 on the invitation of some former colleagues that worked there. It felt very culty at the time and I left with the vague feeling that I always got when I left the house of my spoiled and over-privileged friend that I had in grade school. How they were working with the scale of data that they had to deal with was very cool, though.

It’s more so related to power. Once you’ve acquired enough power, it consumes most people. They don’t like having their power challenged or put in a weakened state. Many of these people are acquiring power via some form or their “genius”. Technical wunderkind, military strategy genius, etc. So that drives their ego. But, they probably know they’re not actually a genius and plenty of people could have done what they did but they got lucky. So they end up getting defensive and insecure when anything challenges their power, risks to expose their genius as a fraud, etc. They’re operating on a mental house of cards and are volatile due to it. For regular people, they seem to be triggered by small things like losing a card game but it’s probably just that, a trigger that unleashed a wave of pent up insecurity.

People who can't spin pottery shouldn't be allowed to have bowls, especially mass produced by machine ones.

I understand your point, but I think it is ultimately rooted in a romantic view of the world, rather than the practical truth we live in. We all live a life completely inundated with things we have no expertise in, available to us at almost trivial cost. In fact it is so prevalent that just about everyone takes it for granted.

Clone meant, at least back in the day, that it was compatible with software written for the IBM XT. There were many clones with more ram, 3.5” disk drives, or better CPU (NEC V20) than the original IBM XT but they all ran MS DOS and WordPerfect and Accolade Test Drive and any other software you would expect so they were considered ‘XT clones’

what are the zeros of the following polynomial:

\[ P(z) = \sum_{k=0}^{100} c_k z^k \] where the coefficients \( c_k \) are defined as: \[ c_k = \begin{cases} e^2 + i\pi & \text{if } k = 100, \\ \ln(2) + \zeta(3)\,i & \text{if } k = 99, \\ \sqrt{\pi} + e^{i/2} & \text{if } k = 98, \\ \frac{(-1)^k}{\Gamma(k+1)} + \sin(k) \, i & \text{for } 0 \leq k \leq 97, \end{cases} \]

I tried for a while to do the whole "notebook life" thing that was really trendy to blog about some years back, but found I never had the notebook I wanted on-hand (even if I was just using one notebook...) or forgot to grab a pen or can't find a pen et c. Then making it possible to find anything in them requires more effort afterward.

What do I have on me basically all the time? My phone.

I've done everything in Apple Notes for years now, and it's so much less hassle, and actually works for me. I just make sure to include words I might use to search for a note, when writing a new note. Search does the rest. I can and sometimes do organize things into directories, but usually it's kinda wasted effort. Search is enough.

Meanwhile, the few dozen pages scattered across four or five notebooks that I generated in that brief kick remain, passively, a pain in the ass. I've carted them through two moves, meaning to digitize them, because when I remember they exist and browse I'm like "oh yeah, that was a good idea!" but, out of sight out of mind and when I stumble across them I'm always in the middle of doing other, more important shit.

It requires two-way communication, which makes the system more complex, with all the negatives that come with it.

Cars are not very secure by nature: they have easy to break glass windows, and are made of relatively lightweight materials. The key system just needs to match that level of security, and AFAIK, attacks on the keyfob are uncommon compared to other, less subtle techniques.

The more complex and sensitive "PKES" system, according to the article already has a challenge-response system, but it doesn't help with relay attacks.

Spot on. Modern jobs are 100% transactional with very few exceptions.

This is a relatively new development, and there ARE some counterexamples available among the large employers local to me, but you can't assume you'll get one. (In Houston, for example, if a long-term employee of an oil major is on the "layoff list" close to a tenure milestone, they'll find a way to keep them -- 20 years is a magic number for retention of insurance here.)

PEOPLE can be worthy of loyalty, but in a large corporation being loyal to a manager who is 4 layers down the tree is silly. You can and will be laid off by people who don't know your name. It's one reason I've stayed in smaller firms. I'm loyal to MY boss, because he owns the firm, and because he's showed ME loyalty.
Show HN: High-performance GenAI engine now open source
by fryz | 2025-04-24 13:55:19+00:00
Hey HN

After one too many customer firedrills regarding hallucinating or insecure AI models, we built a system to catch these issues before they reached production. The Arthur Engine has been running in Fortune 100 to AI Native Start-Ups over the past two years, putting security controls around more than 10 billion tokens in production every month. We're now opening up this service to developers, enabling you to leverage enterprise-grade solutions to provide guardrails and evals as a service, all for free.

Get it on Github (https://github.com/arthur-ai/arthur-engine) to start evaluating your models today

Highlights of Arthur's Engine include:

* Built for speed and scale: It performs well with p90 latencies of sub-second well over 100+ RPS

* Made for full lifecycle support: Ideal for pre-production validation, real-time guardrails, and post-production monitoring.

* Ease of use: It is designed to be easy for anyone to run and deploy whether you're working on it locally during development, or you're deploying it within a horizontally-scaling architecture for large-scale workloads.

* Unification of generative and traditional AI: The Arthur AI Engine can be used to evaluate a diverse range of models from LLMs and Agentic AI systems to binary classifiers, regression models, recommender systems, forecasting models, and more.

* Content-specific guardrail and detection features: Ranging from toxicity and hallucination detection to sensitive data (like PII, keyword/regex and custom rules) and prompt injection.

* Customizability: Plug in your own models or integrate with other model or guardrail providers with ease, and tailor the system to match your specific needs.

Having been first-hand witnesses to the lack of adequate AI monitoring tools and the general under delivery of Gen AI systems in production, we believe that such a capability shouldn't be exclusive to big-budget organizations. Our mission is to make AI better, for everyone, and we believe by opening up this tool we can help more people get to that goal.

Check out our GitHub repo for examples and directions on how to use the Arthur AI Engine for various purposes such as validation during development, real-time guardrails or performance troubleshooting using enriched logging data. (https://github.com/arthur-ai/engine-examples)

We can’t wait to see what you build

Every response in this thread rephrased as a reply to “an integer is a 32 bit binary twos complement”

1. there exist other ways to represent an integer

2. An old computer uses a different representation

3. numbers are displayed in base 10 on my monitor

4. when I type in numbers I don’t type binary

5. twos complement is confusing and unintuitive

6. it’s more natural to multiply by 10 when using base 10

7. I’ve used 32 bits to represent other data before.

One dyslexia font was tested and found to have the same legibility as normal fonts:

"Dyslexie font neither benefits nor impedes the reading process of children with and without dyslexia."

https://link.springer.com/article/10.1007/s11881-017-0154-6

I'm skeptical that any of these fonts actually make a difference. (Although if you like Comic Sans, you might as well continue using it; it doesn't do any harm.)

To gauge how well the models "think" and what amount of slop they generate.

Keeping it secret because I don't want my answers trained into a model.

Think of it this way, FizzBuzz used to be a good test to weed out bad actors. It's simple enough that any first year programmer can do it and do it quickly. But now everybody knows to prep for FizzBuzz so you can't be sure if your candidate knows basic programming or just memorized a solution without understanding what it does.

- if you want to have comments or backtracks, you can do it with ActivityPub without having people signing up to your site (directly or through some OAuth system)

- If you want to mitigate spam, you can set up your AP blog to only accept messages on the inbox from actors who you whitelist.

- You could have your own Substack where you only send the updates to actors who are paying subscribers.

The article didn’t make that conflation at all. The author, a former professor of mine in law school, knows what he’s talking about (as do I). It was the commenter who was confused (as are you).

Jurisdiction has nothing to do with whether laws are applicable to a case. It has to do with whether a particular court can hear a case. Personal jurisdiction questions go back hundreds of years to resolve issues like “is it just to force a defendant to travel hundreds of miles by horse and carriage to defend himself?” versus allowing him to defend himself closer to home.

If the plaintiff sued Shopify in New York, this issue wouldn't have come up at all. (And, yes, a New York court can apply California law.)

This stuff is all covered in first-year civil procedure in law school.

You want to know if a new model is actually better, which you won't know if they just added the specific example to the training set. It's like handing a dev on your team some failing test cases, and they keep just adding special cases to make the tests pass.

How many examples does OpenAI train on now that are just variants of counting the Rs in strawberry?

I guess they have a bunch of different wine glasses in their image set now, since that was a meme, but they still completely fail to draw an open book with the cover side up.

Congratulations on your launch, the animation makes it seem like a neat product!

I don't think I've ever seen a "coming soon" pricing page before <https://colanode.com/pricing/>

For my curiosity, your readme mentions Valkey but the docker compose uses Redis - is that on purpose? https://github.com/colanode/colanode/blob/v0.1.3/docker-comp...

You will also almost certainly want to either use the Apache 2 version of Minio[1] or label that dependency as AGPLv3 to ensure folks are aware. I would also recommend always pinning image versions, because you don't control what that project does or doesn't do in releases

Pretty sure that we’re talking apples and oranges. Yes to the arbitrary byte sequences used by tokenizers, but that is not the topic of discussion. The question is will the tokenizer come up with words not in the training vocabulary. Word tokenizers don’t, but character tokenizers do.

To our questions from Germany:

- by Post, but I can imagine this changing as payment via phone/watch/... is spreading and I can imagine banks willing to reduce cost, making physical cards an paid extra.

- on my contract via e-mail and the energy company's website. There are paper based contracts available, though.

- In Germany/Europe SEPA wire transfers work well for that and are being used for decades, even with online banking being wide spread in the 90ies. (Pre Internet via BTX https://en.wikipedia.org/wiki/Bildschirmtext )

How do you encourage people to continue making new typefaces if anyone could use them immediately? FWIW, it does take significant time to design individual typefaces. It’s not just a set of characters: it’s the character in lowercase and uppercase, how letters appear differently when adjacent to certain other letters, punctuation, etc.

A significant amount of time goes into the process.

Others have already written in their comments on this post about how silly the idea of loyalty to a company is.

I think all I'll add to that is that I have ended up at the point where I doubt I'll ever give my "best" work to an employer again - I'm just there to put the JIRA tickets in the bag, so to speak.

My best work is now exclusively reserved for things in my free time that I have a personal interest in.

But negative, but success is correlated to success so much that at some point work and talent are irrelevant. Let's say Zuck has an idea to make something. He has enough people around him discussing ideas that he can basically pick one he likes and it's already pre-filtered. Then he can give it to basically anytime he chooses, with arbitrary skills threshold and resource allocation. Then he's got a whole support network to make it work. And if it falls? A loss of a few millions means nothing to him and he can try again.

Every step of that is inaccessible to someone hardworking and talented. So let's say you got lucky once or was born with wealth available to you - you can skip the whole talent and work thing.

I probably say something similar to this. I plan to create for the rest of my life. I'm also trying to build a business out of this because I hope that someday it will give me even more freedom and maybe even extend that to my kids and grandkids, if I were successful enough. It also means that I can set my own priorities. I'll likely retire when I'm 65 (too late but I don't think I'll be prepared enough to do it earlier) and continue to "work" on my own stuff, maybe until I die.

But, yes, I've seen some of the world and I want to see more of it. I have a couple groups of friends that hang out more than once a month and I've traveled with them multiple times this year. I have family that I see pretty often. There's really not enough time for all the stuff I do but I'm still driven to create.

The idea of retirement is literally thousands of years old at this point. Hell the Roman Empire even had the idea of pensions though it wasn’t that common at the time.

Aging inherently means being unable to be an independent productive member of society at some point. (Ed: well past what we consider retirement age.) Historically in agrarian societies few people reached this point so it wasn’t generally a significant burden to support them. What changed is lowering the retirement age and increased the number of people who live long enough to see it.

I meant it's it's physics job to produce light. If it does that efficiently, great! That's one thing you should want.

It's human job is to convey information. If you're measuring efficiency that way, it would be most efficient to have the dimmest screen possible (using the least energy) as long as you can still tell what's happening on screen. If that's already happening, then surely a screen twice as bright as you need it to be would use twice the energy and be half as efficient, even if it physically is equally as efficient making light at any brightness.

You could be using half the energy to do the "same" job.

> I will wager that the cost of compliance will dramatically increase, however.

What makes you confident in that assumption? Because I would wager that cost of compliance is gonna be pretty much negligible, because manufacturers have most of the numbers already anyway, and this pales in comparison to EMF testing, too.

Estimates for effects of the regulation are right there-- they hope for total savings of 8TWh within 2030, but mainly from longer product lifetime through devices staying functional for longer on old batteries and easier battery repairability.

I always wonder what kind of projects are we talking about. I am currently writing a compiler and simulation engine for differential-algebraic equations. I tried few models, hoping they would help me, but they could not provide any help with small details nor with bigger building blocks.

I guess if you code stuff that had been coded a lot in public repos, it is fine, otherwise AI does not help in any way. Actually, I think I wasted more time trying to make it produce the output I wish for than it took me to do this myself.
