No they didn't. The grant application to study laplacian equations mentioned that they would use some of the funding to broaden the range of scholars who could participate.

You can't have DEI in math itself because it's fundamentally abstract. One might as well demand to know why there's any funding larger than that required to run a stationary cupboard because mathematicians famously only need pencil and paper (unlike disciplines such as physics which also require wastebaskets).

Math doesn't require complex equipment, exotic materials, or long0running experiments. The biggest resource need you could point to is compute power, but it's basically a people discipline, where math nerds need think time and the ability to lay out their ideas with other math nerds in faculties and conferences. And such people may be found anywhere, there's no guarantee that they're going to bubble up naturally through the academic selection system. Ramanujan is he canonical example.

You could suggest it during initial setup. You could advertise the feature beyond a weirdly named setting at the scroll-down portion of the iCloud page. You could call it something more descriptive like “end to end encrypted iCloud”, which would distinguish it from other security features. You could periodically ask users to do checkups, and verify that their backup contacts are still active and available — even if they’re not actively using ADP.

The best analogy I can give is the way Apple gradually raised MFA from an optional feature with 1-2% adoption to a recommended feature that had majority adoption (even if it was not required.) They did this by heavily encouraging users to turn the feature on during setup, and then bugging them about it after setup. Apple is capable of encouraging and advertising security features it cares about, even when there’s risk.

I think do nothing except vote is a trap. It shows how weak our political immune system is that people think it's only about elections.

Call or write your Congresscritter. Concisely express your concerns. Seriously short. Someone listens/reads the message, ticks a box that summarizes your concern, tallies the checked boxes. It isn't personalized like some might wish but your opinion is counted.

If the actual response exceeds the expected, then some feel good pandering might occur. But in large numbers of complaints, it can move the needle.

If everyone did it, there'd be more responsive government than merely voting. Of course not everyone does it. But in aggregate your call/email has an effect when you do it regularly and tell others they should.

What if even 1/10th of the complaints on social media went to Congresscritters? They'd respond differently.

Join a peaceful assembly. Join two.

If we do nothing that is permission. What comes next is election shenanigans because why not? What stops that if the people have already shown they don't care?

I showed up to the C++ rodeo right as C++98 was taking off, and got to work with Jaakko & Gaby & Bjarne (at TAMU) on what would be C++11 (C++0x). Man — those were great times. I still can't decide which craziness — reflection or coroutines — I detest worse in "modern" C++. In either case, I really feel like I'm channeling my inner/outer old-man-shakes-fist-at-clouds. On the other hand, I see languages like Nim, Zig, Rust, Swift, Go, ... and, I mean, seriously.

The only real example I can think of is the US options market feed. It is up to something like 50 GiB/s now, and is open 6.5 hours per day. Even a small subset of the feed that someone may be working on for data analysis could be huge. I agree CSV shouldn't even be used here but I am sure it is.

Most of them aren't coinflips, and all of their outcomes are strongly dependent, and you don't have to call it until the coin is about to land.

It does boil down to predicting a coinflip of 'Which party will outperform the polls (and by roughly how much).'

And getting three of those in a row is, while not trivial, does not in itself a dynasty make.

The big five are hardly the only purveyors of for profit works.

Go back through any list of the great works and you’ll find a great deal of populist authors. Shakespeare, Dickens, Herman Melville, etc were producing the exact kinds of works you’re looking down on.

Perhaps something fundamentally changed, but it seems more likely bias is talking here.

failed operation? Have you seen the war map? After the whole world dumped all their stockpiles to ukraine for over $500B, the russians have still taken over a 3rd of the country. Biden logic was going to lead to a american troops on the ground, and a vietnam all over again.

Russia didn't punch us in the face, they punched some dude that we barley knew in highschool half way across the world.

The NSF is a big part of the startup community in the US: sponsoring pitch competitions; partnering with universities; educating scientists on entrepreneurship, business, and commercialization.

It's sad to see this administration attacking startups and entrepreneurship in the US. Startup community volunteers will have to work that much harder at a time when traditional employment is less and less palatable.

I think it’s hard to “get” modern art with no context. I think you can start by asking yourself: “what am I looking at?”.. and just reply yourself .. out loud .. in your mind… however .. then .. explore what you feel .. what it reminds you of … etc. It’s also sometimes useful to see the progression of that specific artist.. if it’s a famous artists they tend to have a “style” .. you notice that in a way they are trying to do the same thing over and over .. perfecting something throughout the years so it sometimes helps to see their early work. I can recommend the book “what are you looking at?” By Will Gompertz.

Having said that… no need to feel bad about “not getting” some work of art .. sometimes it’s quite literally impossible to “get” an artwork if you don’t know certain things .. kind of like not understanding a word because it’s in a different language.

Because with a blog I have time to think and edit and have full control of the page if I ever change my position which, without the whole picture, I sometimes do. Where as if I post a reply it is often a gut reaction that later I sometimes regret making. I often grimace at some of my older comments on here and other sites which I cant alter or remove.

I also wrote a post recently on why it is sometimes dangerous to make these type of un-thought out comments that people can trace back to the real you, I think that part scares me more than anything https://rodyne.com/?p=2154

Thank you for the vote of confidence. :-)

I do ask myself that sometimes. It sounds weird, but I think it's what I was put on this earth to do. Yes, it is a cruel industry at times and pain is indeed inflicted just as you assert. I guess I'm just built for it. And I've been doing it for so long that I've built up a really thick skin and I'm just not that fazed by its unpleasant aspects. I can honestly say that it's a fun job. It's the job I always wanted when I was a kid and I still absolutely love it. (I'm fortunate enough to be compensated at a reasonable level, so that helps.)

People think it's stressful and I suppose it is. But the nice thing about it is that when the newscast is over, I'm completely done. And I have the luxury of knowing, down to the exact second, when that moment will be. I don't take my work home with me. There's nothing to stress out about (until the next day.)

Another thing... unlike an airline pilot or a surgeon, no matter how poor a job I might do, no one dies. That's kind nice too. :-)

His language may be childish, but he is historically on the spot:

There is absolutely no record of any slave 'race' of any Canaanites in Ancient Egypt, no kind of exodus, nor any kind of major event in that time period that could lead to such an exodus. The closest that could simulate an 'exodus' is the !likelihood! of some Canaanite people who may have come with the Hyksos in the Hyksos invasion going back to Canaan. Or, some local people who collaborated with the Hyksos, thinking that it could be better to go with them to avoid the ire of their own countrymen, who conquered Lower Egypt after 100 years.

People tried too hard to find anything in Ancient Egyptian history, records and events that could validate Moses, 'slave Semitics' and the exodus story, but until now, there is absolutely nothing. The most likely thing, if you try hard enough, could be the leaders of the people mentioned above, who may have potentially existed, inventing a 'promised land' story to persuade their people to go to Canaan. And even that is too big a stretch. The entire thing can easily be a mythology local Canaanites invented to justify their rights to the land without anything like it having happened.
Show HN: Built QR-code SaaS with 30% recurring commission-open to early partners
by 0xgautam | 2025-05-09 20:35:58+00:00
Hey HN,

I’m from QR Code Developer, a simple SaaS tool for marketers and creators to generate & manage dynamic QR codes.

It came out of frustration watching small teams overpay for bloated QR tools that lacked affiliate features or analytics transparency.

We’re keeping it clean: privacy-first, no-nonsense pricing, and analytics.

I’m currently onboarding a small group of affiliate partners (30% lifetime recurring commission) and would love feedback or thoughts from the HN crowd.

Here’s the site: https://qrcodeveloper.com/affiliate AMA or DM—happy to share more behind the scenes.

Eh, this isn't a great theory especially for the poor.

As a higher income individual I conversely seem to have a lot of time to study and am not given a constant stream of work I must complete every moment. I also have the benefit of working from home and being able to spend a lot on training and upskilling.

When you are poorer you typically don't get this. The vast majority of your income is spent at the end of the week. Your job gives you zero time to explore and learn more. You likely commute and and may have a second job to make ends meet.

Just saying 'learn to code' here doesn't address the systematic issues.
Ask HN: Anyone using knowledge graphs for LLM agent memory/context management?
by mbbah | 2025-05-09 20:36:35+00:00
I’m building infrastructure for LLM agents and copilots that need to reason and operate over time—not just in single prompts.

One core challenge I keep hitting: managing evolving memory and context. RAG works for retrieval, and scratchpads are fine for short-term reasoning—but once agents need to maintain structured knowledge, track state, or coordinate multi-step tasks, things get messy fast; the context becomes less and less interpretable.

I’m experimenting with a shared memory layer built on a knowledge graph:

- Agents can ingest structured/unstructured data into it - Memory updates dynamically as agents act - Devs can observe, query, and refine the graph. - It supports high-level task modeling and dependency tracking (pre/postconditions)

My questions: - Are you building agents that need persistent memory or task context?

- Have you tried structured memory (graphs, JSON stores, etc.) or stuck with embeddings/scratchpads? - Would something like a graph-based memory actually help, or is it overkill for most real-world use?

I’m in the thick of validating this idea and would love to hear what’s working (or breaking) for others building with LLMs today.

Thanks in advance HNers!

The "sane center" is a dying fantasy only kept on life support by the DNC to justify the same old mummies holding on to their last vestiges of power as everything burns down around them.

There is no compromise that can be made here. The Democrats spent this past election cycle trying to appeal to 'undecided' 'independent' voters by shitting all over their actual base and presenting policies that appealed to about exactly zero people.

Take immigration, for example. There is no way in hell the Democrats could have ever beaten the Regime on this issue. So what did they do? They still tried to compete by hardening their views to appeal to 'undecided' 'independent' voters who then all promptly headed to cast off their votes for the Messiah. All they managed to achieve was to piss off their base and anybody who'd considered voting for them.

What 'moderate' (which is really just an euphemism for cowardly) Democrats don't understand is that you are in the opening stages of a war, and the last thing you ever want to do is purposefully disarm yourself because of 'decorum' and 'acceptability' and other such nonsense.

You can never make compromises with those who want you dead no matter what. Hopefully the Democrats learn that before everyone in the world has to pay the price.

I actually work in the industrial repair industry. The thing to remember is not every company is insanely rich. Maybe top level companies but they are supported by a wide network of smaller companies. Those smaller companies don't have a ton of money to throw around. The manufacturers of the equipment have become quite greedy. The majority of them offer whole systems and then if anything breaks they want to charge an insane amount to send out a field engineer. And then if something is broke most of the time they either don't carry that part/panel/whatever in stock and will try and upsell you to the new model which is of course a massive investment.

So repair shops fill the gap for all these smaller companies and factories to get support higher than the on staff maintenance. Not everything is fixable though. They may use unique hardware signatures on drives or FPGA's or PAL's with security bit enabled. That has been true for a while though. Even in consolidation there is still plenty of business and repairs to be made.

Conversely the medically industry might be a good example. Anyone making medical equipment has to provide documentation on it. Which makes them far more repairable and easily diagnosable.

TV's especially are peak commodity. They are so cheap that the skilled labor cost to fix them isn't economically. They also are not easily transportable so repair and resell is a rough business for them. Things like laptops and phones though seems much more reasonable. Plenty of people do that professionally or even as a hobby. I like a large portion of repairs on those types of devices can be fairly economical and Chinese part makers provide plenty of affordable parts. It would cost OEM's extra to keep these parts in stock, but it's not a terrible hard task. Providing schematics also isn't a huge ask. Most are reverse engineered anyway.

When it comes to security I think this is fairly simple. Provide a blank security chip and create a secure method to connect and program it. Apple does this with its self repair when it comes to matching hardware UID's in the firmware so all the functionality is unlocked. Companies like Apple and Samsung can keep their Knox and Secure Enclave/exclave. Data can be seen as something that is not repairable in most cases. But they can provide the parts the secure a device again and leave it as a blank slate.

The biggest problem with Right to Repair is pricing. Right now Chinese makers can whip out parts for really cheap. Comparing to official parts from Apple or Google or Samsung when they did sell them and they are way higher and sometimes prohibitively so. Would be better to treat it like auto parts. Where you can get the OEM part or the third party part and both can work. Some things like security would need to be first party, but that would be a great deal. So it's doable, but would require a LOT of political will against tech companies. So it's just a really tough sell to get to that point.

If you are going to use Babbage as the start of the clock, we must use the mechanical and electromechanical logarithmic and analytical engines created in the late 1800s/early 1900s as the stop.

We must also use 1980 as the year in which quantum computing was "invented".

As far as progress goes, in all of those fields there are naught but papers that say "quantum computing would be totally rad in these fields" or simulations that are slower than classical computers. (by, like, a lot)

I disagree. There has been some criticism of his experiments, but don’t forget that the experiments were successfully replicated many times, by different researchers and in different countries. Don’t forget either that Milgram was surprised by the results; his advance prediction was that Americans would comply with authority far less often and that he would have to repeat the test with Germans to see a high level of compliance. Instead there was essentially no variation between the nationalities that were tested. If he had been deliberately faking the data then that would not have happened. He also repeated the experiment a number of times with varying circumstances. His best results were that he could get both more compliance out of his test subjects as well as less compliance by controlling how closely related the test subjects were to the supposed victims. People who already knew the supposed victim were much less likely to comply than strangers. This suggests that he was measuring a real effect.

Some of the criticisms are valid, and the results to not reflect well on us as people. The 33% of people who can keep to their stated ethics in the face of authority probably have a really hard time believing that 66% of people cannot. To them it seems easy and obvious that you just don’t violate your ethics. But imagine it this way: for hundreds of thousands of years humans lived in tiny tribes wandering in the wilderness. Failure to heed the orders of the tribe’s leaders would have been a virtual death sentence for most of that time. That environment literally breeds for people who obey even when they think it’s a bad idea. That’s apparently not long enough for the trait to have become universal, thankfully.

I don’t know about the TPSE though. I didn’t cite it either.

Definitely, with backend agnostic code you can target only a common set of features. It's convenient to use where it makes sense as it reduces the complexity: 1 kernel for all backends. And you can actually go a long way with this without sacrificing too much of the performance.

But for squeezing maximum performance & using latest features you have to target each device individually.

bigstrat2003's argument is approximately "Python is batteries included"

My counter argument is that the "batteries included" approach tends to atrophy and become dead weight.

Your counter seems to be "that's not an argument, that's just Rust hype."

Am I interpreting you correctly? Because I think my argument is salient and correct. I don't want to be stuck with dated APIs from 20 years of cruft in the standard library.

The Python standard library is where modules go to die. It has two test frameworks nobody uses anymore, and how many XML libraries? Seven? (The correct answer is "four", I think. And that's four too many.) The Python standard library has so much junk inside, and it can't be safely removed or cleaned up.

A standard library should be data structure/collections, filesystem/os libraries, and maybe network libraries. That's it. Everything else changes with too much regularity to be packed in.

Why should they leave without creating institutional knowledge and educating those who come after them... That is how it was before the 'mainstream tech' and its 'turnover/after me, deluge' mentality took over and made shareholder capitalism made every employee a disposable cog. That is what all orgs. should return to now that the zirp ended and shareholder capitalism is kaput.

Modems are part of the ISP's network. Where does the ISP's network end, and your network begin? You might be tempted to say it's at the wall jack, but your ISP is tempted to say it doesn't, and your computer is theirs too.

In the past (and again on some fiber networks), there was https://en.wikipedia.org/wiki/Network_interface_device and the separation occurred there.

Note that it might not be the same at L1 and L2, e.g. your ISP may own the physical lines up to the side of your building, and the data link layer up to your modem.

Your hubris would be justified had every media outlet and pundit been talking ad nauseam about how Trump was absolutely going to sweep the field, but they didn't. Harris losing was a shock to many, many informed people.

I've been a Ruby dev since 2006 and started using Sorbet fulltime at work about a year ago. After about six months I started wanting it in my personal projects. Not enough to add the dependency, but if Ruby had it built-in I would probably use it. For myself, it makes it easier to work on code I'm not familiar with either because I didn't write it or I wrote it longer than X days ago.

The Sorbet syntax is pretty bad, though. And things go from bad to worse as soon as you get a bit tricky with composition or want to do something like verify the type of an association.

I haven't tried inline RBS comments yet, but the DSL does look more pleasing.

The team in general had mixed views. Some hated it, some liked it, most developers just don't really care–although now the Sorbet advocates are claiming it helps the AI, so now there is that leaning on the Sorbet lever as well.
