What does this look like in practice?

It seems jj supports this workflow roughly as well as Sapling. If I have five PRs open with five feature bookmarks, changing an ancestor and pushing will update all PRs simultaneously. Github's PR view notices that the heads were updated and changes which commits are included in the review set.

Sapling shares the limitations of Github's review UI: reviews still include all changes (I think). The only nice bit is Sapling automatically submitting the PRs for you and adding the descriptive info?

As a nifty workaround, it looks like sapling recommends an external tool called reviewstack.dev to properly review its stacked PRs which show incorrectly by default on GitHub. So is there much difference?

This is a super cool visual demonstration of RTOS/scheduling! I love the region-based critical sections!

I took a real-time operating systems course in university as an elective. One of the hardest courses I took the whole four years, but also one of the most interesting. Had a great professor, who gave really demanding, but very instructive, project-based assignments.

I need to find a toy project to play around with this domain again.
Tell HN: Visually distinguish the username of the post creator in discussions
by ahmedfromtunis | 2025-05-28 20:32:39+00:00
I suggest to visually distinguish the username of the post's creator within the discussions below their post.

Personally, this would save me from having to go to the top of the page often to (re)read the poster's username -- and losing my progress in the discussion in the process.

Also, I think such feature would be especially valuable in Ask HN and Show HN posts, where interactions from the Ask-er or Show-er can be integral to the discussion.

A simple way to do this with minimal visual noise would be to bold their username whenever they comment in the discussion.

Perhaps a limited test run in just these types of posts could be a good starting point.

The article makes statements that the test were getting more difficult:

>> In addition, norm-referenced tests [STAAR] are designed so that a certain share of students always fail, because success is gauged by one’s position on the “bell curve” in relation to other students. Following this logic, STAAR developers use practices like omitting easier questions and adjusting scores to cancel out gains due to better teaching.

Followed by:

>> Ultimately, the STAAR tests ... were not designed to show improvement. Since the test is designed to keep scores flat, it’s impossible to know for sure if a lack of expected learning gains following big increases in per-student spending was because the extra funds failed to improve teaching and learning, or simply because the test hid the improvements.

>> Texas’ educational accountability system has been in place since 1980, and it is well known in the state that the stakes and difficulty of Texas’ academic readiness tests increase with each new version, which typically come out every five to 10 years. What the Texas public may not know is that the tests have been adjusted each and every year – at the expense of really knowing who should “pass” or “fail.”

What is not clear or known for sure is the gains, gained, from an increase of money spent per-student because the test, by it's nature, is designed to be flat and not show improvements. But the test itself is designed by the developers to cancel out gains by making it harder. Therefore, the test could not be used to assess that. It is just written a bit funny.

This hurt the lower income students most as the wealthier schools with better teaching resources improved faster, it made the test more difficult for poorer performing schools. This is used as a measure to close or take over schools by the state. There's a bit of a kerfuffle going on currently about some schools getting F ratings and the state wanting to take them over, which in other states that might be okay, by here -- they are about to mandate that the 10 Commandments be displayed in classrooms[0]. They are also on track to getting rid of the STAAR test[1]. Hopefully the new assessment they replace it with will be better, supposedly it will be to show improvements, I fear it will then fall into the "no child left behind" trap that STAAR may have prevented by keeping scores flat, even with major investment in education; but it may also help lower income students who are hurt by the current testing practice in that they will receive the funds they earned for their improvement instead of losing them because wealthy districts outpaced them in gains -- even thou they both gained. Texas is weird sometimes.

>And I'm telling you that 1, 2, 3, 4, 6 are the ones that are active right now.

I trust genocide watch more than you to determine which of the genocide watch stages of genocide are underway,

>How does any of that help "undo" the damage done by apartheid?

White South Africans make up 8% of the population but own 72% of farmland. This is a direct result of apartheid and colonial racism more broadly. Expropriating some of this land and returning it to black South Africans is directly undoing this damage.

Conversely, Chris Spargot did a great video about government-run pubs during WW2 in Britain, where the government offered good wages to workers who would help make shells, and then recruited all the local barkeepers under a decent steady wage to stop the workers from bribing the barman to give them more alcohol.

so was considering doing a rewrite of a Next project to Remix.

but then, as I look into it, Remix is now actually React Router v7. that seemed odd, even though I knew the author was the same I was always under the impression that these are distinct projects.

but fine, perhaps the evolution of both has converged. I got too confused to invest time in the rewrite. now, seems like Remix is being rebooted?

all these changes over the years seem well intentioned, but it takes away confidence in investing time in these solutions. If the justification to rebrand completely to React Router was that there are no serious functional differences between it and Remix, having a hard time understanding why Remix is now in the picture again.

CRTs are very forgiving- 512x342 vs x384 would have made very little difference. You could still get square pixels by minor adjustments to vertical and horizontal size.

My question is what is the htotal and vtotal times in pixels and lines? Maybe there was a hardware savings to have vtotal exactly equal to 384 (which is 128 times 3). Perhaps they saved one bit in a counter, which may have resulted in one fewer TTL chip.

The wealthiest family India lives in multigenerational skyscraper. Others in multigeneration compounds / culdesacs.

East Asians overwhelming move to nicer / larger apartments or urban villas before fucking off to suburbs with shit schools and bad travel time to nice large, cities.

Rich in poorer/develping countries with shit urban centres may pick private suburbs for privacy/security, because they simply don't have choice / access to world class urban living.

Nu-urbanists are kind of delulu, but they (probably) know more than "normal humans" when it comes to spectrum of livable build enviroment, the vast majority haven't lived in a nice 200-300 sqm apartment in a tier1 city. Most see medicore suburb living > medicore city living.

Ultimately it's not even that expensive to make that kind of housing (i.e. extra sqm construction $$$ to odor and sound proof units is not much). It's much harder to build nice cities people (or rich) want to live in, vs easy to spam livable single family unit suburbs.

That said, housing (and access to services) preference is almost seperate discussion from single family vs communal / multi generation living arrangments. Plenty of people would not want to live with extended family even if culture compels them too. And plenty of people probably wish family was closer.

>she's absolutely succeeding according to the values of capitalism.

It is not entirely clear why you call these the values of capitalism. These are universal human values that do not depend on the economic formation.

If anything, capitalism makes people less cynical, simply because it is designed to function independently of such qualities in people. While in many other systems, cynicism, cruelty, unscrupulousness and deceitfulness of people are simply ignored, giving people with such qualities huge advantages within the system and ruining the lives of everyone else.

RE: Pocket, I could care less as I've been an Instapaper user for years, but it does give one a hint at the direction Mozilla has been on for a number of years now...

RE: Fakespot, this one really really hurts. Even if the ratings weren't accurate sometimes, it helped guide me in the direction of finding and distinguishing bad/fake products from good (or good enough). I always wondered what their business model was... Sad to see that their competitor Reviemeta also died out. Is there no hope for an alternative to these? Any thoughts on making a service like Fakespot and having it be profitable or at least self-sustaining? I can only think of a subscription service for having curated reviews, maybe prioritizing reviews from susbscribers...

IAAL (but not a practicing one, so I don't have skin in this game, and this is not legal advice). I also once lost $25k+ in a copyright litigation relating to music piracy before I became a lawyer. It was decidedly not fun.

You ignore a C&D at your peril. The rules are complicated and the fines and penalties for not following the rules are expensive. U.S. IP law is fiercely protective of patent rights, trademark rights, and copyright. It's not something you mess around with, and anyone who tries to defend himself without a lawyer is a god damned fool. The author of the blog post did the right thing by engaging and trying to work something out without coming across like "go pound sand, I do what I want."

Please don't walk around giving bad advice like this. I pray for the poor sap who listens to it.

Good times, when you were able to restrict information export through airport security... Don't forget Paypal and Wikileaks! Oh my bad, that was Bitcoin talk. That's not a currency anymore, but an asset. Like gold.

> Doing inference for many of these models is readily available at modest consumer hardware availability.

Then why exactly do I need a darknet service for that, instead of running it locally?

> Now you either (a) use only AI from the good boy list and get outplayed in the global marketplace where our main export is global technology or (b) start acting like a Chinese citizen and using a VPN to access AI services not available only on the approved good boy list.

Yeah, businesses are totally gonna buy tons of crypto to pay for outlawed services from China to stay competitive. Instead of running models locally as you suggested above. And of course the government will just fold in face of this crypto enabled libertarian hell.. I mean utopia. Can't beat math, amirite? There will be no more taxes, everyone will be free, armed and get as much fentanyl as they want, and we will just build a Dyson sphere around the sun to power this awesome new financial behemoth. It will be so worth it.

Better invest now!

I see there as being two main types of people who’d benefit from using LLMs for booking flights.

The first are power users, in the sense of people who have complex requests. Like those who’d ask for the cheapest flights from Manchester to Turkey during the summer school holidays for without layovers unless those layovers were in Paris, for a holiday to be roughly 10 days long, excluding very early morning flights. Such a request could be made with existing OTAs, but would be painfully time consuming.

The other type of user for whom LLMs might be useful are the opposite, those with very loose requirements. Think “get me a flight to a warm place tomorrow”.

Skyscanner etc would still have value for the people in the middle.

Probably depends on the customers and the products. I'm not into gaming handhelds, but for my other battery-powered electronics, battery life is probably the most important characteristic. Charging things is a real hassle, and the less I have to do it, the better. Particularly when so many of these things don't have user-replaceable batteries.

But I know there are others who prioritize other aspects over battery life.

AMD also segments, even with respect to ECC. Not all Ryzen CPUs support ECC, officially or unofficially. IME, it's easier to find or build a low-power, ECC-supporting server system based on Intel than AMD, though that says more about Intel's robust channel partner network. Nominally, more of AMD's product range supports ECC than Intel's.

I don't think that .ai is automatically filtered in this case, it's more of a case by case basis. But it's killer nevertheless. "Adult themes" for example is a large umbrella at OpenDNS, and for example I wanted to check the lyrics of a song I was listening to, and it was hosted on darklyrics.com. Nope, couldn't visit, because it's Adult Themes.

> I often see the halting problem misconstrued as "it's impossible to tell if a program will halt before running it." This is wrong.

> The halting problem says that we cannot create an algorithm that, when applied to an arbitrary program, tells us whether the program will halt or not.

Or more simply:

No program can tell whether any program will halt or not.

Prohibition also had the effect of largely killing off the small breweries started by various immigrant groups in the United States.

When it ended, the industry rapidly consolidated around the large-scale industrial breweries which have dominated the market ever since.

This is a big reason why the beer industry in America is weird. You have large mass-market brewers on the hand one, and small craft brewers making more creative beers on the other hand, but you don't have many medium-sized brewers making high-quality traditional beers.

It's pretty hard to compete with Europe in that segment.

* This looks awesome. I'm looking forward to proof by demonstrated real-world production-grade project, and experience report of same.

* The awesomeness might be more clear once there are toolkit/framework layers above this low level. Just like a first demo of simple things in Svelte doesn't show you the complexity and bulk of Svelte internals by which that is implemented.

* Maybe someone will have an idea for some killer application of this that makes it appealing to more than just the people who already know they want to use Scheme. In the past, one such idea was to use first-class continuations to implement Web forms UI more easily, and another was to use Scheme to implement rich meta data model in a tractable way that would've been tons more work in the alternative of the day (Java). Or maybe the killer feature doesn't come down to a fundamental strength, since today in theory you can shoehorn JS to do most things, but you come up with an all-around elegant solution that only happens to use Scheme, and it's so great that people like it anyway.

There was definitely a period of (at least subjective) declining battery life in the 2010s but IMO things are shifting the other way. Some devices these days have much improved battery life over what came before, like Apple silicon, the Steam Deck, and most flagship phones. They're not always an order of magnitude better than the past, but better enough to unluck many use cases (doing a long work session away from a charger, being able to game for several hours anywhere, and not worrying about having to charge my phone until I get home, respectively).

If I had to describe it loosely, we've had 3 "eras" of battery-powered computing:

- Relatively simple devices (like the Gameboy) that lasted forever, because they just didn't do much - Full-featured personal computing finally becoming "viable" on mobile devices, but with a clear cost (I remember <1 hour battery life laptops) - More power-efficient HW and kinda-sorta-maybe-starting-to-be optimized SW that makes full-fat mobile computing much more bearable

>I was also surprised to learn that they were paid differently by job.

US does this in roundabout way. Medical officers have various Special Pay along with Flight Pay, Flight Deck pay and so forth. Not to mention various bonuses for various ratings that have come and gone.

It makes sense from manning standpoint since certain ratings will have siren call of civilian jobs compared to others. (ITS, CTN vs YN, RS)

I don't have an exact preference on the kind and weight of the paper, but I do prefer notebooks with firmly bound and numbered pages like old-school laboratory notebooks [1]. My problem is that I often do long derivations or work that can span dozens of pages with diagrams, etc. If I use loose leaf paper like printer paper, I often lose track of pages or their order. I tend to label my pages extensively when I have to use printer paper. I also use binder clips instead of paper clips since they are much more secure. That system works for me but other people might not like it.

Show HN: StandChamp – App to help standing desk owners building healthy habits
by lilohass | 2025-05-28 20:42:12+00:00
Hello all! I am launching today StandChamp - A macOS app that aims to help standing desk owners to build healthier moving habits: https://lilohass.com/standchamp

I bought a standing desk a long time ago and absolutely loved it. In the beginning, I switched between standing and sitting multiple times a day — but over time, I started to forget.

I looked for an app to remind me to use my standing desk more and build healthier habits, but I couldn’t find one I liked. So, I decided to build my own.

The app helps you stay motivated by tracking your sitting and standing sessions, tracking your current and beast streaks, and sending customizable reminders!

I hope you like it! Let me know if you have any feedback!

It's never been an official index.

This is conjecture but I'm pretty sure the idea of it even being an "index" is a stretch. More like people who work in disaster relief talking about their jobs informally. "I just got back from Town A. They had a tornado but it wasn't too bad. The Waffle House stayed open." "I'm heading to Town B. They've been having flooding so bad the Waffle House has been closed for 12 hours." That sort of thing.

Edit: Apparently FEMA contacts local businesses including Waffle Houses in the areas affected by a disaster to ask how they are doing. This makes sense as an added source of data to gauge the severity of an emergency. Still a stretch to call it the "Waffle House Index".

> I wouldn't ask for 100 different versions of the same feature from each of them.

You wouldn't because human labor is too expensive to make it worthwhile. You would if it were too cheap to meter.

We actually do that at the scale of society - that's market competition in a nutshell. Lots of people building variants of the same things, then battling it out on the market. Yes, it's wasteful as hell (something too rarely talked about), but we don't have a better practical alternative at this point, so there's some merit to the general idea.

(Also the same principle applies to all life - both in terms of how it evolves, and how parts of living organisms work internally. Actively maintained equilibria abound.)

I honestly find DENSITY is the core problem with getting rid of things easily. I've sold nearly everything from a 6-person sectional to a small 10 pack of Chinese tea and everything sells OR you can find a home for it on the local Buy Nothing. Usually I get pickups within 1-2 days on all these things.

It is a great case for more city style density (even in Brooklyn which is closer to 3-4 story walk-ups)

> even at a glacial pace

If speed is truly not an issue, you can run Deepseek on pretty much any PC with a large enough swap file, at a speed of about one token every 10 minutes assuming a plain old HDD.

Something more reasonable would be a used server CPU with as many memory channels as possible and DDR4 ram for less than $2000.

But before spending big, it might be a good idea to rent a server to get a feel for it.

Electron doesn't seem to support it (and even if it did, I suspect most electron developers wouldn't pay it any mind) but...

NSApplicationDelegate's -(BOOL)applicationShouldTerminateAfterLastWindowClosed:(NSApplication *)sender; method exists so an application can, uhh, automatically terminate after the last window closes.

https://developer.apple.com/documentation/appkit/nsapplicati...

It's not 100% consistent but if you look at Apple's applications based on single window (calculator, system preferences, etc), closing the window quits the app.

Distinction is suburban vs urban isolation. Making family residencial space more comfy =/= retreating to single family unit outside urban areas op described. Many east asians still try to knit together multigenerational arrangements if they can afford it, i.e. having extended families live in units of same apartment complexes. I mean granted you can do that in suburbs too, but objection with ops claim is people with money don't default to big private spaces in burbs... especially in dense countries with urban areas where it's PIA to get into city. In which case it's better to stay in city but get nicer spaces. Those with resources will coordinate so family is close. It's not communal housing arrangement but it facilitates communal child rearing. Of course if you have absolute fuck off amount of money you buy a penthouse or mansion depending on lifestyle preference and pay someone else to raise the kids.

Part of it is respecting your customers regardless of whether they are aware of your crappy electron app consuming all their RAM and draining their battery or not. If I went to a mechanic (car analogy incoming) that repaired pressurized lines with duct tape instead of hose clamps because I wouldn’t care as long as the car worked, I would be upset, regardless of whether or not it got the job done.

Take pride in your work and respect the people using it.

>US does this in roundabout way. Medical officers have various Special Pay along with Flight Pay, Flight Deck pay and so forth.

Everyone gets various special pay depending on their command and those don't compare to the Australians varying pay largely by role.

>It makes sense from manning standpoint since certain ratings will have siren call of civilian jobs compared to others. (ITS, CTN vs YN, RS)

I'm not sure what you mean by this. If you are deployed on a ship then everyone has "siren calls". All 4 of those rates earn the same money and get additional pay for command based increases unrelated to their rate specifically.
