I think it's partially excusable. Most LP solvers target large-scale instances, but instances that still fit in RAM. Think single-digit millions of variables and constraints, maybe a billion nonzeros at most. PDLP is not designed for this type of instances and gets trounced by the best solvers at this game [1]: more than 15x slower (shifted geometric mean) while being 100x less accurate (1e-4 tolerances when other solvers work with 1e-6).

PDLP is targeted at instances for which factorizations won't fit in memory. I think their idea for now is to give acceptable solutions for gigantic instances when other solvers crash.

To quote from an article* cited by TFA:

> The Internet Archive has long offered a system called the Open Library, where users can “check out” digital scans of physical books. The library was based on a principle called controlled digital lending, where each loan corresponds to a physically purchased book held in a library — avoiding, in theory, a piracy claim. It’s a fundamentally different system from programs like OverDrive, where publishers sell limited-time licenses to ebooks on their own terms.

> However, the Internet Archive expanded its library project during the covid-19 pandemic. It launched the National Emergency Library, allowing an unlimited number of people to access the same copies of ebooks. That’s when the publishers banded together to file the lawsuit, targeting both online libraries.

Now, maybe that article is mistaken or I'm misinterpreting what it says. If the lending is indeed controlled and goes 1 loan per book, which I know it was before that NEL thing, I've got no problem with that, and it seems like the publishers also didn't. If my reading is correct the publishers only went after IA after the NEL initiative launched.

I knew I was in the presence of a hard-core programmer when my interim advisor unironcially used sed to make a tiny edit to a config file. He just up-and-used it correctly like the first time. I was amazed.
I agree with you and at the risk of self-promotion, that's why we built Cloud 66 (which takes care of Day-1 (build and deploy) as well as Day-2 (scale and maintenance) part of infrastructure. As we all can see there is a lot to this than just wrapping code in a Dockerfile and pushing it out to a Swarm cluster.
Application of the 1/R2 gravity formula to the pointwise mass with R->0 can easily power your Romulan ships. In similar vein applying that classical gravity formula - which is valid only to spherical masses or masses at such large distances that they can be treated as such - to the stars inside disk galaxies gets you the "dark matter", and thus not surprisingly the flatter the disk galaxy the more "dark matter" :)
You are misreading a descriptive take with a normative take. The problem is that defined benefit plans are not possible. If you actually care about old people, rather than caring about scoring internet points yelling at people online, then the correct solution is to understand the problem, and start dealing with it.

The "yell at anyone explaining that defined benefits plans are impossible and then give out defined benefits plans anyhow" is what is and will continue to hurt people. It's not people like me hurting people, it's people like you who insist on living in fantasy because my gosh isn't the fantasy nicer than the reality.

Yes, but that's a different problem.

Although it's also tangential to the essay, which is about the mechanisation of self-image - not just sell-worth, but identity in general.

Which has always been socially imposed (even on those who are sure they're different). But now it can be directed algorithmically by a very small number of actors, who have the power to apply behaviour and value modification tools that can be individually tailored for everyone in a demographic - in ways which most people aren't even aware of.

"Low self-esteem" is just one the effects.

Yeah the buttons are actually tactile switches - it was hard to find ones that fit but eventually I found a good match on Ali express. You want 4.8x4.8x0.55mm smd thin film tactile switches. [1]

Only one button was malfunctioning but I replaced them all since they looked pretty worn.

If you’re thinking of switching to micro usb you might as well try usb-c. AFAIK you’ll still need to deal with alignment issues. The resistors are only necessary if you want to use modern PD chargers - they make little boards with these attached already but it may be impossible to fit one of those.

TBI is a wide spectrum of conditions akin to "trauma" in psychological terms.

I skimmed the article, but I didn't see any specific medical terms used. The reason I am curious is because I do not think that mTBI like concussions cause brain swelling since the injury is more of a functional injury than a structural injury.

I like to play ice hockey as an adult, and I try to do everything reasonably possible to protect my brain from vulcanized rubber disks flying at my head at 0 < x 100 mph. Perhaps I will add some fish oil back into my diet. I already uses Lion's Mane, but I am not sure if it truly does anything, but I love the taste of the product I use, so I will continue to use it regardless. Not sure if I have ever had a "real" concussion, but definitely some ringers.

It depends on physical activity. For people working sedentary jobs, washing clothes after one day is probably not needed. For myself, I find I can wear clothes two days without issue. In the same vein, I like to shower every two days. Of course if I smell myself in the evening I will take a shower regardless of the when I last showered.
> Let me offer some alternatives to "autistic": Anhedonia, schizoid personality disorder, avoidant (attachment OR personality disorder).

You are right, except in my case I’m pretty sure it is more autistic than any of those - our children do X/Y/Z and professionals tell us “those are signs of autism” (one child diagnosed, the other not yet formally but the paediatrician is convinced she has it and on the waiting list for an assessment) and (for many but not all of them) I’m thinking “what do you mean that’s a sign of autism? I was like that when I was a kid too, some of them I am even still like that”

> The holy war between vim and emacs is like a bunch of machinists arguing over whether they prefer a lathe, or an entire machine shop that also includes a lathe if you want it.

IMHO not really a fair comparison. There are signifcant differences in the feel and the workflow between using vim and using emacs in evil mode. Other people have preferences that differ from yours. I have many years experience using both vim and emacs (in evil-mode), and I see both sides. Don't get me wrong, emacs in evil mode is great, and I would not want to be without it, but it does not 100% reproduce the workflow of logging in to a terminal and editing text there in vim.

The differences are significant. I'm not saying the experience in emacs is bad, it's just different. If you already have, say, 10 years of muscle memory built up from using vim in a terminal, it will take a fair amount of adjustment to move to an emacs/evil-mode way of doing things.

I personally see no reason that I have to pick one or the other, and at present I spend a lot of time in both editors. I realize that would drive some people crazy, but I'm OK with my preferences being a little unusual.

Libraries lend out the physical book, they do not make a copy. It is allowed to make copies of physical book, so Internet Archive can archive books, but can't make a copy for someone else. It does not matter if also have a physical copy or lending to one person at a time. The physical book is special because not making copy and lending physical object that own.

Also, the Internet Archive did have a program during the pandemic of lending unlimited copies. That is what pissed off the publishers and got them sued.

A couple of companies I've been with found great success by building learning materials for the areas we serve, but also adjacent areas.

Basically, by focusing on educational content for your customers, you get them on your web site when they are just starting to learn about the problem area you cover, and this becomes a great organic lead generator.

Obviously, content farms and constant Google algorithm changes require remaining active and producing more content, and having good site metrics and scores, so it's not necessarily cheap. But the companies I've been with never got penalized because it was real content written by people for other people.

I've Built a Monitoring Tool
Hello, I worked on this little baby in the past months and I'm happy to share it with you :)

You can already follow all the following metrics:
- CPU usage
- CPU distribution
- RAM usage
- RAM distribution
- Swap usage
- Swap distribution
- Network traffic
- Network latency
- IO usage
- IO metrics
- Top process CPU usage
- Top process RAM usage

Currently, the features are pretty basic for now but I will add tons of nice stuff:

analytics for Redis/Postgres/Mongo/.. custom dashboards and graphs, custom metrics monitoring, security scan (CVEs reporting), logs live streaming, Remote process management, etc

If you have a bit of time, please test it, break it, hack it, contribute, I really like to have any kind of (constructive) feedback on this project!

Grim Outlook for Antarctica's Thwaites Glacier
yeah you're on to something. What I would want as first and reasonable step is to talk about absolute numbers of CO2 per person(/state/company/whatever). Only then talking about reducing (e.g. in percentages) does make sense. Instead we have all the campaigns about this or that that don't really adress the general issue that it's all about _absolute_ counts of e.g. CO2 (or in this case microplastic).

But I want to give the article some slack: They basically said that in the UK the number of wash loads increased by nearly 10% without any positive effect (my interpretation); thus we may reduce our amount of wash loads by at least as much again. Also helps with the bills.
I really appreciate that someone else shares my opinions on this matter. It pains me what we do to animals for our benefit. I suppose there is no other alternative, but that does not diminish the cruelty.

I feel the same way about the "Boar's Head" meat recall in the US due to Listeria. 7 million pounds of meat must be disposed of. That means every single one of the pigs died for that meat died for absolutely nothing at all. It just doesn't sit right with me.

What happens when the $1200 phone breaks before it's paid off? Does the carrier replace it?

I prefer buying used phones so I don't have any experience with that...except the first phone I bought... I understood from Verizon that the phone was included in the plan. Turns out I owed $300 for a dumbphone at a time in my life where $300 was a lot more than I wanted to pay for a phone.

I replaced it with a used smartphone for $20 a year later.

It’s good to look at physical systems like this to understand how we’ve landed up with software systems which we take for granted.

For example, when I was about 10 in the early 90s, I remember being taught how to use our school library which at that time had no computers.

The books were sorted on the shelves by author’s surname, so finding them when you knew the author was easy, but what about when you only knew the book title?

Well the solution to that was to look through little cards in a series of draws sorted by book title, when you found the card it had the author name and you could then easily find the book.

These cards were called index cards.

Software databases model this system. A clustered index is essentially equivalent to the books being on the shelves in a particular order, while a normal index is like the index cards.

Email was essentially modelled off of real world postal systems.

And when I read this article talking about standard box sizes, I think of cluster sizes on computer disk drives.

Software is a lot less abstract than a lot of people may realise.

In my 25+ years of experience, any code you write today, however beautiful you think you wrote it, will get stale in a few years and has to be changed/enhanced to adapt to the new reality.

With experience, you learn to find balance between pragmatism and purity more often than not. You will still not always be right.

It is all still a mix of skill, experience, team and external factors.
I use to be pro-phone ban in schools but with all the creepy crap going on in public school systems, I think kids should be able to record their teachers/other students/staff.
I think the implication is that there is probably a much more reasonable way to do what I was trying to accomplish, and I didn’t do that. That is almost certainly true. This was my first time trying to film such an extreme time lapse so it is quite possible that I wasn’t aware of some tools designed for it
I fully expected an llm hooked up to an image gen ai that turns weather forecast into hyper realistic images, and was pleasantly surprised to see a good old deterministic mapping of data onto carefully chosen visuals in a system where an actual human made actual design choices. how strange!

> even further toward infrastructure, the slower and more thoughtfully you should move. These things often have far less rapidly changing requirements

I used to think that, until I worked on my first large scale system, infra heavy. It turns out it works both ways.

If changing infra is hard, slow, painful and risky, people will be less inclined to do so. If changing infra is fast, easy, and with low risk, people will be much more inclined to change things.

Even if you had very stable requirements (doubtful in this day and age), I see no reason why you wouldn't build your system in a way that is easy and safe to change, for the day when it's needed.

Prohibit phones in AP classes, allow phones in the GA or remedial classes. If a parent complains about their kid having to put away their phone, then they can switch classes to be with the rest of the distracted kids. Normally you'd be wary about creating this kind of segregation, but with the loss of effective intelligence from being tethered to a surveillance industry terminal, this arrangement would likely end up expanding access to AP classes.
I do hope I never have to use a UI designed by that author.

Age old SV question. But they both have large networks and their original idea either outright failed or is a dying off.

Trying things one foot in, one foot out.
Yes definitely. We wrote a multi-step reasoning engine similar to o1. Depending on the route and depth in the chain of response, prompting techniques vary. The LLM router was pretty important to get right. On input: synthetic question enhancement has yielded positive results. Asking the right question is subtly important, and we find it is sometimes better to just slow a user down and help them improve their question instead of relying on multi-step reasoning from the get go. On output: checking answers via mixture of experts and other techniques is often necessary -- "truthful but wrong" answers are where some tricky gotcha's lie. Eval is hard.

One under-discussed feature of fast databases is that they are especially necessary in an agent-centric world. E.g. if you're running recursive SQL to pathfind towards an answer, it has to happen with minimal latency otherwise you break the user experience. Our interface looks like a spreadsheet and users mentally benchmark against spreadsheet-latency speed. They won't accept 20 second query response times they might get from their data warehouse.

A) …why? What makes this interesting to physicists? I understand this as “if stars weren’t stars but instead rigid spheres, and if they were in an impossibly-impervious giant sphere, then weird stuff happens”. And…?

B) “since stars rather rarely collide” still blows my mind. I did some napkin math on Reddit a while back on why there will be very few stellar collisions (really, one star falling into another’s orbit?) when andromeda collides with the Milky Way, and the answer is that space is just mind-bogglingly huge. Even the most dense clusters in our galaxy are akin to ~70 1cm diameter spheres per olympic swimming pool.

Christian mythology is powerful because of the idea that God loves you so much he will give you infinite chances to repent and turn away from sin for as long as you live. Carrying guilt and shame for your sins won't fix them, but being sorry for them and working to sin no more will fix your future.

It was even more powerful in an era when the gods were vengeful in their retribution and/or capricious in their favor. I'm not saying I like it or agree with it, but it does really bring some form of comfort to people, which is why it spread so far and lasted for so long.

>Knocking happens from pre-detonation, that's usually caused by heat from compression causing the fuel/air mix to ignite before it's triggered by spark.

No, it usually happens because the normal flamefront from the spark causes a rise in pressure that triggers compression-ignition in other parts of the cylinder. It's not solely from the compression, usually. That scenario is rare primarily because as you reduce the knock margin, you'd hit knock from what I said before you get to the state where it's so bad it ignites from compression alone.

https://www.researchgate.net/figure/In-cylinder-pressure-tra...

Look at this picture; this is a typical waveform of cylinder pressure vs. crank angle. The spark happens 28 degrees before TDC, so basically the left edge of each of the graphs. As the flamefront consumes the air-fuel mixture inside the cylinder after the spark, the cylinder pressure gradually rises. During knock events, the cylinder pressure as risen by the normal combustion process gets to a point where it starts igniting the fuel elsewhere in the cylinder, away from the gradually expanding flamefront. This causes rapid combustion which causes the pressure to rise suddenly, which causes damage to the engine (if severe enough)
Right, it wasn't criticism, but the point I added (that I think was not explicit in the article) is this: black holes provide a lower bound on the potential energy, not just an indication that the model is breaking down.
