I implemented passkeys @ $WORK, and we rolled it out to our tech department only first. Nobody could make it work reliably, and troubleshooting it was basically impossible. The best you could do was just wipe their passkeys and have them try again.

I've since disabled passkey support and we have no plans to attempt a new rollout anytime soon.

As far as I can tell the only people that have "successfully" rolled out passkeys are the companies with effectively zero user support and they just refuse to support passkeys at all, so if they don't work for a particular user: whatever.

TOTP is fully rolled out and well supported. Troubleshooting it is "hard", but at least it's possible.

TOTP troubleshooting basically boils down to 3 things:

* Server time

* User Phone/device time(most users opt to use their phone to generate TOTP, but we don't care)

* More than one TOTP saved for a given site(i.e. they didn't replace the old and created a new TOTP shared key) or not saved at all.

Our tech/user support helpdesk can handle this but it took a lot of training. We built special tools. We still get requests from them when they get overwhelmed with the complexity.

Passkey troubleshooting:

* Mobile network, including bluetooth

* Server network connectivity

* Computer/device network, including BT connectivity to mobile device.

Most tech support can't handle that much complexity at once. Shoot, most developers and tech "whiz" people can't either. The error messages one does get, if they are lucky, are very general and not helpful at all(last I checked).

Passkeys are not currently fit for production where you have to support the users. I hope they get there.

1Password is the only client/device implementation of Passkeys that pretty much just works. It saves the passkey in the 1p vault, and the 1p vault can be synced across devices.

For analog photos the negative also has more dynamic range than your screen or photopaper without any of that. Contrast is applied in the darkroom by choice of photopaper and enlarger timing and light levels, or after scanning with contrast adjustment applied in post processing. It is really a storage medium of information more than how the final image ought to look.

Slide film has probably a third the dynamic range of negative film and is meant as the final output fit for projection to display.

I know everyone thinks this is a bus, but as a regular bus commuter in the bay area, I think there is room to expand here that a bus can't always meet. A few problems:

* Bus stops are often far from homes and offices * There’s rarely parking near stops so you can't drive to it * Routes are fixed and rarely change. * The process for petitioning for a new stop is painfully slow and done based on rough approximation of demand, community input, budgeting, and other red tape. I can't even guess what data they use to decide. * Many people can’t or won’t walk long distances to reach it. * The websites, maps, and schedules for buses are often very bad and hard to interpret

I can see someone like Uber filling a gap here with a shuttle service (not low density cars or SUVs).

* They have hundreds of thousands of users in a metro area. * Get those users to enter where they live, where they need to go, and roughly at what time. * They find a group ~30 people with similar locations, routes, destinations, and times to create a route * It doesn't have to be door to door. Just an acceptable walking distance at both ends. * Dedicated stops don't have to be approved and built. Just pull over on a major street. * It is extremely easy to use Uber

No idea if this can be made economical of course. It also sounds like a really hard problem to solve.

Yes. Because it's a vague unbounded take-home exam and when companies pull stunts like this, they're usually looking for candidates to go 'above and beyond'.

I've done take-homes before and have been rejected because I followed the prompt to a tee and only did the exact amount of effort they wanted, and was quite literally told that they expected me to do more (outside of the prompt). If you've done enough of this game then everything in the OP will be extremely familiar to you.

I'm surprised I'm not able to find this out - can some one tell me whether AlphaEvolve involves backprop or not?

I honestly have no idea how AlphaEvolve works - does it work purely on the text level? Meaning I might be able to come up with something like AlphaEvolve with some EC2's and a Gemini API access?

5 (maybe) - Over the past decade or so, it became really common to job hop for higher salaries, and while that did give a lot of broad experience, it may not have done nearly as much for depth. Everything from tech stack to data being worked with to broader architectural decisions that affect maintenance. I'm wondering if companies have noticed this and are shifting away from job-hoppers to get better return on investment.

Yes, and I love it! Finally, the volume knob control was pulled from producers all about gimmicks to push their productions.

There are still gimmicks, but at least they do not include music so badly clipped as to be unlistenable... hint: go get the DVD or Blu-Ray release of whatever it is and you are likely to enjoy a not clipped album.

It is all about maximizing the overall sonic impact the music is capable of. Now when levels are sane, song elements well differentiated and equalized such that no or only a minor range of frequencies are crushed due to many sounds all competing for them, it will sound, full, great and not tiring!

Thanks audio industry. Many ears appreciate what was done.

I haven't had any problems with syncing and using passkeys with 1Password and Firefox on MacOS, iOS, or Windows. When the site wants to create or use a passkey I get a prompt from 1Password on the device that I'm using. No need to involve a second device (which for me I'm fine with security-wise. If I really wanted to be sure there was no way of malware extracting the keys I would be using my Yubikeys)

One thing I've noticed in music composition (where I have more training/experience, but I suspect the same is true for narratives) is the rules get codified / standardized a generation after a style of music is popular. Bach, for example, "breaks the rules" of counterpoint at least once in every piece in Well-Tempered Clavier, which was supposed to be an educational piece so if he actually felt like there were rules to follow he'd be more likely to be "by the book" for educational purposes.

But the rules of counterpoint were codified after his death (IIRC there were two people who worked together to do it), and act like an averaging across all baroque composers. Making the rules is kind of like putting it in a glass box, sealing it off and preserving it - IE removing all life from it. A contemporary example is how punk became standardized, just wear leather jacket with safety pins and mohawk and play barre chords. The spirit of punk moved to post-punk and elsewhere but also this bizzaro copy of all the superficial aspects of punk moved elsewhere.

While I love Joseph Campbell and the heros journey, I do feel like sticking too strongly to it does the same thing for narratives. I especially hate insistence that everything needs a three act structure, not because it's inherently bad, but because stories that don't need it are shoehorned into it and given an unneeded third act with more set pieces than genuine character motivation and development. It's like people see a good movie with a three act structure, and think it's due to that specific structure.

I think this administration (well Trump because I'm not sure anyone else is calling the shots) already is inclined to point at the sky being blue and declaring "the experts were wrong see" and banning iced tea for whatever reason.

Amusingly / sadly it fits a weird almost meme like internet logic where folks post "I was told that..." and they insert some absurdity to make their point seem more reasonable.

I'm semi convinced this kinda twitter / social media thinking is actually how Trump thinks. Everything is a short blurb, even just an insult, no thinking beyond that.

Well most raw vegan food is already way cheaper that raw meat:

Quality organic dry chickpeas, lentils, beans, soy etc… already are around 2€/kg where I live and when you add water they double/triple in weight so you end up at 1€/kg. You’ll probably eat a bit more weight than meat but still the price is nowhere comparable. Add some whole cereals instead of white bread for nutrition and better satiety: they’re more expensive but you got the price back on the quantity you eat (you won’t stuff yourself that much T165 bread or brown rice: the fibers will make you feel full super fast). And for the vegetable you usually can find stuff super nutritious for cheap : apples, leak, cabbages and alls sorts of oignons.

Even fancy organic quinoa is like 10€/kg but also double in weight and you only eat ~1.3 times the meat weight you’ll eat in meat-meal.

Industrial chicken is 5€/kg un the shop and "good" one 15€/kg. Quality beef is nowhere in that range.

As an author of this paper, I am very excited see the great discussion here!

Several people mentioned the generation - compilation - fixing loop. Just want to remind you that our approach works for not only the generation step but also the fixing step. This is because fixing is essentially asking LLMs to generate a new version of the code. The paper actually has a "repair" experiment to demonstrate this and our approach achieves significant gain in this experiment, i.e., 37% relative improvement in functional correctness.

Every time I see one of these I'm reminded of the AMFare system [0] which was tried in the 60s. It was basically the American fast food version of this. No AI, just hundreds of special purpose mechanisms to make burgers, hot dogs, milkshakes, etc. Never took off and was apparently a nightmare to clean.

I just had a look at the wikipedia page for the company behind it (American Machine and Foundry). AMfare isn't mentioned, but there is a section called "Bowling pinsetters and nuclear reactors".

I find the default HDR (as in gain map) presentation of iPhone photos to look rather garish, rendering highlights too bright and distracting from the content of the images. The solution I came up with for my own camera app was to roll off and lower the highlights in the gain map, which results in final images that I find way more pleasing. This seems to be somewhat similar to what Halide is introducing with their "Standard" option for HDR.

Hopefully HN allows me to share an App Store link... this app works best on Pro iPhones, which support ProRAW, although I do some clever stuff on non-Pro iPhones to get a more natural look.

>Most of the big shore places were closed now and there were hardly any lights except the shadowy, moving glow of a ferryboat across the Sound. And as the moon rose higher the inessential houses began to melt away until gradually I became aware of the old island here that flowered once for Dutch sailors’ eyes—a fresh, green breast of the new world. Its vanished trees, the trees that had made way for Gatsby’s house, had once pandered in whispers to the last and greatest of all human dreams; for a transitory enchanted moment man must have held his breath in the presence of this continent, compelled into an æsthetic contemplation he neither understood nor desired, face to face for the last time in history with something commensurate to his capacity for wonder.

>And as I sat there, brooding on the old unknown world, I thought of Gatsby’s wonder when he first picked out the green light at the end of Daisy’s dock. He had come a long way to this blue lawn and his dream must have seemed so close that he could hardly fail to grasp it. He did not know that it was already behind him, somewhere back in that vast obscurity beyond the city, where the dark fields of the republic rolled on under the night.

>Gatsby believed in the green light, the orgastic future that year by year recedes before us. It eluded us then, but that’s no matter—tomorrow we will run faster, stretch out our arms farther. . . . And one fine morning—-

>So we beat on, boats against the current, borne back ceaselessly into the past.

Articles like these, deliberately it seems, fail to recognize that in the infinite conceptspace that is reality, there are attractor zones where threads converge - archetypal stories that have been told and retold over time for a reason. Try telling a story that doesn't strike an archetypal chord and see what happens - it lands in the void.

"A mechanical engineer created a new kind of baseball bat and made the baseball bat companies more money."

See? No one gives a shit.

"A mechanical engineer created a new kind of baseball bat, it changed baseball forever into a minmax-optimize-at-all-costs bore show that killed a cultural icon of a sport and while the engineer got rich in the process, he couldn't have predicted the cultural effect his invention would have or how we would lose himself in the process."

Ok, now we're onto something.

Stories are anchored to conceptspace attractors and condescending them as simply "Western constructs" belies how humans actually come to care about things.

duckdb is primarily a query engine. It does have a storage format, but one of it's strengths is querying data where it already resides (e.g. a parquet file sitting in S3).

There are some examples[0] of enabling DuckDB to manage distributed workloads, but these are pretty experimental.

lol you're not wrong but it's more like 2-3 hours of setup in 2025. It's usually just a plugin in HA or HACS nowadays.

Nobody is using arduino's with HA anymore. You can order hardware that works out of the box for nearly everything. A wifi enabled light is dead simple.

All OP would have to do is order an RGB light that works with HA, plug it in, add it and then setup an automation. HA has made all this doable through the UI now, so no YAML unless you really want to. I have like 15 of these for my garden setup.

Great comment. I grew up with the "life sucks" and "work harder" mentality. Both of them eat you up inside, and I lost at least a decade to doubling down on them when they didn't work well over time. Sounds like this book will be interesting in more ways than I expected.

I’ve encountered cheap drip machines, and I’ve encountered pricier drip machines. I have never encountered one that didn’t have an utterly terrible path for the water.

And even some rather nice Breville espresso machines have something like three buttons and a couple little LEDs. They work well, but good luck deciding the blink pattern meaning “you must descale me now” and actually running the descaling cycle without a manual.

That interesting article led me down a research rabbit hole of microwave maser inferometers and whether that could be an explanation for the controversial Havana Syndrome. And, having skimmed descriptions of historical SIGINT projects Buran[1] and Luch[2], and the theoretical advantages of such a system ... my curiosity in Faraday cages is renewed.

Good read! Just a thought:

At some point, current NK's regime will fall. After that, will NK IT sector quickly find its place in the wider world? (I mean: legal, trusted / respected etc). Or will its ties to current NK regime attach a "black sheep" stigma to anything/anyone IT related from NK, for decades afterwards? What do you think?

Btw: there's 2 aspects there: how quick NK IT workers (or companies) would "turn legit", and how outside world would view/treat them as such.

And is commonly used for authentication codes, and like Social Security Number, it is PII that should be default-deny.

Github seems to have no legit need for a user's phone number. Since there's not even a way to tell them to go pound sand, I'd say opting out of disclosing sensitive information they don't need by not signing in/up and equating their unreasonable demand with a ban is respectable.

Very excited about this! I used CedarDB a while back for my bioinformatics research when Clickhouse started running into OOMs, and the difference was astonishing (Some details: The main query was a join of 100 million rows against 30.000 rows, then aggregating statistics for the entire table. Clickhouse used up well over 64 GiB of RAM + 100 GiB of Swap and then crashed, while Cedar used only 15 GiBs and finished quickly).

Ever since attending the advanced database lecture of Thomas Neumann at TU Munich, who wrote Umbra, the academic predecessor of CedarDB, I've been looking forward to everyone getting their hands on it!

I believe Cedar will enable tons of projects and companies to simplify their data stack because it can basically handle everything at once (until reaching very significant scale).

The first rule of Show HN is, "don't give me a playground where it looks like I can push the button and then force me to auth when I actually do click the button, expecting magic on the other side."

The second rule of Show HN is, "YOU DO NOT FORCE USERS TO AUTHENTICATE AFTER THEY'VE CLICKED THE BUTTON."

The description seems to invert RAG: RAG (simplified a bit) conducts a search, presents the results to an LLM, and then the LLM produces output based on the search. In GAS as described the LLM analyzes the input query to generate the search query, then a search is run, and the results of the search are presented to the user. With GAS, you always get specific authoritative (to the extent that describes the universe searched) documents, any hallucination will impact document selection not correctness of info. Wtih RAG you get an LLM analysis of potentially many authoritative (with the same caveats as before) documents, but hallucination can affect the accuracy of the presented response as well as its relevance.

This can be generalized to stories about any kind of real-life racing. For example, there's a whole genre of videos about the history of speedrunning video games (competing to complete the game in the fastest time), popularized by the works of Youtuber SummoningSalt:

https://www.youtube.com/@SummoningSalt/videos

These are presented in an entertaining way that's full of twists and drama, but because they're non-fiction they can't be forced into any pre-existing structure.

I find this plot structure tired and boring so I'm always on the lookout for movies that don't follow it. They are hard to find! (Also, I probably don't have an excellent memory to recall them later when I do find them.)

Horror movies in general seem to have more freedom to play with plot structure than other genres. Every film, regardless of plot, needs to have something that makes the audience want to watch to the end of the film. With horror, it's often putting the question in the audience's mind "what is happening?" That can be compelling enough to propel the viewer to the end so the film often doesn't need to have a protagonist go through some emotional journey.

It's been a while since I've seen them, but I don't think The Ring or The Grudge follow this plot form. It's probably telling that both of those are adaptations of non-Western films. I don't think Alien follows this structure either: Ridley is basically right all along and just has to survive.

I think Goon is an underrated comedy, and it doesn't really fit the three-act structure well. It certainly has conflict and climax, but Doug doesn't really go through any internal crisis. Instead, he's more often the catalyst for internal change in other characters.

Every machine in my home stack is named after a Pokemon. Theres hundreds of options, each pretty unique, and fun. You also get some sense of scale, in that stronger machines can correlate to stronger pokes.

Beefy desktop with a strong GPU? Name it after a legendary.

RPI? One of the thousand little electric guys. Rotom, voltorb, .....

That daily driver laptop that never leaves your side? I usually pick a starter evo or eeveeloution

Cloud server? Pick a flying type.

It like having a theme to my whole infrastructure. Even my DuckDDNS is named after porygon, the cyber duck.

I don't really buy that.

It sounds more like "i'm picky about a washing machine" has become a personality trait, or a sunk cost, so there's no abandoning it at this point.

Probably gonna find a decent washing machine, then 2 months later another issue crops up. "It doesn't tumble quite right, ugh my clothes aren't clean". It reminds me of old people who say "They don't make x like they used to. Can't buy a good one anymore!"

Again, if the vast majority of people are finding the machine to be adequate, then it's probably not the machine. It's probably the people who are struggling with it have unreasonable expectations.

Domestic chores are also rife with people who do things for no reason other than "i was taught this way". This means their expectations are, often, unreasonable. I'm not saying that's applicable here, but it's definitely something to consider in these areas. Lots of people do wild stuff with their clothes/dishes/cleaning and don't realize it until someone points it out to them.

Author's note: Many readers, understandably struck by the severity of the events, have speculated about the involvement of organized crime. I want to clarify that, while the situation was extremely problematic and dishonest, that wasn't the case. The "worst parts" I alluded to referred to other internal dynamics, abuses of trust, and improprieties that I prefer not to detail further for privacy reasons and to avoid weighing down the narrative.
