Higher Math for Beginners (Mostly Physicists and Engineers)
A very good Soviet era book for Students who have just gotten introduced to Calculus.

The book was written by a team consisting of a Physicist and a Mathematician. As such it teaches Calculus from first principles motivated by concrete problems in Physics (as it should be taught) and not in a abstract manner where the student does not understand the What and Why of what he is learning and doing.

Anybody wishing to learn/understand Calculus can do so just by studying this Book.
The fact that someone actually built this, sent it to the bottom of the ocean, and then put people inside it to weld a 1200km pipeline underwater boggles my mind.

Meanwhile we inexplicably struggle to figure out clean/cheap energy at scale.

I love fastmail and its REST api but also at the same time I love to use google stuff like google docs, calendar etc, google voice. Technically I can use all gmail service without using a gmail account but it's always less intuitive somehow and always something break here and there when people invite or tag you in drive or google docs.

So I ended up build an email forwarding service, it runs on my own domain, forward email[1] back to my personal gmail. So I still have full control at my own domain level, have the flexibility that gmail give me, and have a REST api to access email.

Having this access REST API[2] in hand, I have been thinking I maybe able to scrape bank alert email to build out a a read-only API for my own banking transaction.

As someone who has studied both Esperanto and Indonesian, I'd say they are roughly comparable (although Esperanto is easier). But Indonesian is pretty easy as far as natural languages go. People wonder why anyone would bother as Indonesia isn't really a major country (and most of their population actually speaks things like Javanese rather than standard Indonesian) and would say learning Mandarin would be more useful. Which objectively it is, but I've also studied that, for a considerably more amount of time than I've studied Esperanto or Indonesian, and with less success.
Flutter looked cool, until I realised it was a Google product. After being burned by Angular, Material, and all the things killedbygoogle, I'm not sure I can stomach even trying it out. Is that stupid?
For that, you can use cupy[0], PyTorch[1] or Tensorflow[2]. They all mimic the numpy's API with the possibility to use your GPU.

2,000 per year is still low. Just look at Florida on how bad it can get. Not even sure 350k would cover your rebuild costs given the market. Heard some crazy costs in Sonoma from high demand and not enough construction workers. Hopefully that insurance covers replacement cost if labor triples or more.
I found this section from another page on the same site amusing:

> Nord Stream developed a high environmently-conscious logistic concept which guarantees that transport vessels have not to travel more than 100 nautical miles (185 kilometers). [...] This concept of short trips and environmentally friendly transport saves roughly 200,000 tonnes of carbon dioxide when compared against other options and the use of existing concrete coating plants.

-- https://www.wermac.org/nordstream/nordstream_part4.html

For comparison, each of the two Nord Stream pipelines can (well, could) deliver enough natural gas to create more than 150,000 tons of CO2 emissions per day.
It may be more the myriad of technologies and the fact that they change them out almost as often as their underwear. Same problem we have with javascript frameworks.

What is it that we need 10 years experience in this week? Win32, OCX, DCOM, CORBA, OWL, ActiveX, WinForms, WPF, ASP, SliverLight, .Net, XNA (etc. etc.)?

Kind of amusing that so many people turned to web tech to escape that treadmill and then just totally recreated it in javascript.

If you are going leaded...my favorite is kester "44". Pretty much can't go wrong with it.

IMHO...despite the risks of lead...leaded solder is way easier to use and especially inspect. Lead free often looks "cold" just by the color of it.
Would be interesting to see such an error, but also what's interesting to me is that you are regularly making 'dumb' syntax mistakes, which suggests to me that you're still in the learning process and that you'll internalize the syntax more fully and stop making those mistakes some time in the future.
The Apple Watch is a great example. People said that it looks too nerdy, until they adopt a round screen women won't wear it, etc. But it's been a massive success.

I have Revolut and have encountered this a number of times.

The flow is usually that the merchant runs a check against the card by doing a £0 transaction rather than the correct card active check which resets the card number and causes the second transaction of the correct amount to fail.
Yeah for sure, but this tool is really good for helping you visualize and discover what's eating up your storage, better than anything built in to any of the OSes that I use anyways.
I beg to differ. To at least consider that the sabotage is in US interest, is sound logic.

Of course there are many factors at play and a lot we don’t know.

The arguments in your post carry a hint of denial in them. Read other posts that outline the benefits to the US position after the sabotage, and consider them without bias. Not saying its the only explanation- but the case is worth considering.
> Edit: in the industrial world equipment like this is not in racks/server rooms.

A rack by any other name . . . :-)

TBH I was thinking of not just the trad. IT server room racks but also of cramped radio comms "cupboards" by towers and of production circuit | industrial control access panels / locations in both indoor "warehouse" production and outdoor mineral processing circuits ..

Always handy to have a small known general purpose computer with ports, scripts, utilities, etc when you're tracking down the weird bug of the day.

Yeah. Oil & gas companies are masters of this sort of greenwashing.

They run two transactions, the first being £0 and it resets the card number causing the second to fail.
This doesn't seem drastically different than what was openly happening to Native Americans in the US until the passage of the Indian Child Welfare Act in 1978. By some estimates, as many as 3/4ths of Native American children were taken from their families for adoption or foster care.

And that's assuming the law stopped the practice, some states still see many Native American children shipped to non-Native communities to get federal welfare money.
I'm an enthusiastic supporter of auto-hiding headers and have added them to sites. I don't understand the hate? It's easy to scroll back down again and have the header re-hide (ie overscroll when you see it happening and then scroll down).

To me, this is better usability. I agree - fixed headers obscure the page and it's bad. But simultaneously, it's nice to be able to access the header and navigation instantly. This seems like a good compromise?
Kudos for you on starting a new life long addicting hobby. One of the things in repairs is that sometime you encounter problems that force you to learn new things. Why is there a metal or brick in your wall? What can you do next time to know if a particular wall has a metal or brick? Learning how to solve these kind of problems is what makes them so fun. I've ruined countless things over the years but managed to fixed much much more.

The annoying thing is that this is obviously a setting within Gmail, because our other server is sending the same volume of messages without any issues. Right now it's getting slowly better so I'm not keen to set up extra servers for what I hope is a transient problem.

Other suggestions have been to send all Gmail messages via our working server, but that would cause a spike in it's traffic and I'm worried we'd get the exact same issue there.

Both Microsoft and Yahoo have responsive processes to solve this problem, it's frustrating that Google is so opaque.
Sure. It's quite obvious, too: how many Russians has NATO killed?
Same here. We have eliminated all limits entirely. Same scale (maybe slightly larger). Diverse workloads. In principle we can bring cfs back with like 1ms period but we’d probably look into cpuset pinning first

> Why does it not present hell in any other use case, such as computers, phones

It absolutely causes problems on computers and phones. Windows updates are famous for interrupting/losing work at this point. MacOS upgrades are less aggressive but far more likely to break formerly functional software (and stomp custom configs). Phone security is always an issue if not an outright disaster in dozens of ways. Look up the Qualcomm / MediaTek audio decoder issues from just this year.

Somebody can spy on you and steal sensitive data w/ access to your computer or phone. What can they do with a car?

Have you read the Wired article from 2015 about hackers remotely killing a jeep on the highway?

Some levels of computer security rely on avoiding connecting to public networks. Or any network.

> Why aren't Tesla or Rivian owners collectively going crazy

Just last year there were over the air updates on Teslas where owners reported vehicles stopping without warning. They fixed that promptly with another emergency OTA update, but not exactly a shining example.

Just last month someone I know told me that the performance profile of his Tesla was weird since a recent update.

These are the realities. There's a ton of evidence.
The double accounting has been fixed a while ago. The real issue is poor defaults (100ms period is too long) and generally folks aren’t aware that limit actually sets cfs quota
This is a very insightful remark, thank you.

I focused on 10-Qs for the EDGAR filings module as you rightly pointed out - it seemed to be a good balance between implicit information and usefulness of the data. TBH I didn't actually investigate the other (many) patterns.

Having said that, I have really enjoyed Kai Wu's research from Sparkline Capital (https://www.sparklinecapital.com/), especially his extraction of the innovation factor from EDGAR filing texts. He's appeared in numerous podcasts, and they have all been super useful to listen to.
Maybe someday when I re-investigate EDGAR filings and go further, I might target these signals you talk about here.
Rural people can still live in the forest and away from other people. They just need to be willing to cut down every tree within 100' of their home and use fire-resistant landscaping. The problem is that the trees are pretty.

Correct, he isn't stupid and he invaded Ukraine and you should be more weary about it.

> Also, there's two assumptions here. First that they've destroyed the whole project. What's your source on the repair costs in order to justify that position?

If you search around this thread, the pipeline has an internal coating that cannot be exposed to water and no valve system to isolate and replace parts of the pipe for repairs. I'm just going off that information. But even if it can be repaired it's still very costly, and stupid to do potentially massive damage to your own infrastructure for an unspecified/unspoken 'warning' that people may not even pick up on. I'm certainly not picking up on it. That's a very inefficient messaging system.

> Another assumption you've made is that NS2 isn't a sunk cost for Russia. That's an unjustified assumption given the recent consequences of Russia's energy war on Europe.

It wasn't a sunk cost. It was a nearly operational pipeline that would have delivered extremely cheap natural gas to germany's many factories, way cheaper than other source. Europe is desperate for energy and will be desperate for energy after the war. This is why it's such a great bargaining chip, and why there's a great incentive for the US to destroy it, so they can take away that bargaining chip.
Thanks for sharing some numbers. Assuming 500K MAU, that means around $10000 per month or roughly $120K per year in revenue? And with 50% margin, sounds like you spend around $60K per year to keep the app (and related backend service) up and running?
This is the truth. What's really sad is that we could be saving so much money, energy, and resources preparing for that future but too many people are doing their hardest to deny what is coming.

If you live in an area that constantly floods, where clean water is increasingly scarce, or which is frequently on literal fire you'd be crazy to stay and keep rebuilding, but even worse is that people are still investing and developing in these types of locations as well. Eventually the government is going to have to step in and relocate people, and leave anyone who stays to their own fate, but you'd think more people would see what's coming and save themselves a lot of pain and suffering. Don't waste your time and money on soon to be less than worthless property, find a nice place somewhere safer, and get in while you can.
That is incorrect - hpa works off cpu request not limit (and usage).
They do at some point though, "does it have CarPlay" is actually a major purchasing decision now, when I bought our car I chose it over another very similar car mainly due to this one having CarPlay.

But comparing the UX of two cars' built-in systems when you're test-driving them for 15 minutes is hard, and reviews usually gloss over it, maybe mentioning how laggy it is or isn't and what whiz-bang new feature it has that nobody is going to use.

Unless you're Apple, it's hard to sell UX. But Apple is, well, Apple!
Question for people with fastmail and a .net custom domain: Do you usually get blocked sometimes? I wanted to send an email to my therapist and one email to my insurance but both had blocked me. A mailbox.org address worked just fine.
Is it because of the domain or because of the .net ending?
I have had laptops from them. Bad quality control; misaligned screens, all chargers dead after a couple of weeks on all the machines I owned -- to be fair, they offered fixes and / or replacements for free, but I doubt it was random and I happened to have bad luck receiving just the odd defective ones.

Are they really your allies? The US has blocked flights from Europe during the coronavirus for a long time. At some point, it was possible to go from North Africa, through Turkey to the USA. But people from Europe could not do that; and that's after the coronavirus pandemic was worse in the US.

I think people are delusional if they think the US is Europe best ally. It's not. And they (the US) clearly see Europe as a threat to their rule-based world order.

Bringing up Javascript really doesn't help your argument as it is pretty universally deemed a "poorly designed language". Many, many people have written about this. Somewhat randomly selected is this: https://medium.com/javascript-non-grata/javascript-is-a-dysf... (and it references more).

Later ECMAScript editions have made good improvements, but there are still plenty of sharp edges and footguns in Javascript which simply do not need to exist.

Javascript is a leading language because _practically_ speaking (not strictly speaking) it is the only language you can use if you want to make things happen in the browser. And it came with every major web browser since the late 90s. THAT is why it gained immense marketshare.

Python has been included in Linux, *BSD, and macOS for years. It's a very simple language to make things happen with little effort; it is "accessible" to most people, particularly non computer scientists. It reads a little bit more like English than other languages, and it doesn't require compiling (again to accessibility).

All these things don't mean it's good. But it got picked up by non-developers and used to solve real world problems and a lot of research problems. More and more specialized modules were written for it, making it even easier to solve many problems.

So its accessibility and ecosystem have been good. But that doesn't mean it's good for building big, long lived, easily maintainable or extensible systems. It certainly doesn't mean it's good for building performant systems.

See elsewhere in this thread for my link to my biggest complaints (from an old discussion). I'm not a recognized expert on language design, but I've written significant quantities of production code in several languages, including Python, over many years.

No doubt people may disagree with my assertion, but using popularity as evidence of disagreement is not valid since popularity often does not correlate to the quality or suitability of something. History is full of companies, technologies, and practices where the most popular was absolutely not the best.

There's a related scheme that I've seriously considered a time or two.

I'm a pretty good software engineer, and they pay me very well, but I've got absolute shit executive functioning skills. Task management, remembering to email people back, and the like are challenging to me. It has occurred to me that a full time personal assistant in my area typically makes about $50,000/year. I think there's a decent chance that, with such a support, my own salary could go up by $200k or more over the next couple of years. I've frequently entertained the notion of hiring someone to basically support me in my job without telling my employer, since there's zero chance they'd get me such an assistant and similarly zero chance they'd let me pay for my own.

I wouldn't ultimately do it because, y'know, all the dishonesty involved, but it'd probably be a good deal for everybody involved. My employer gets better work for the same money, my assistant gets stable work, and I get promoted.

Ran into a problem immediately in Japanese.

I asked お名前は何と言いますか？(Whats your name?) and it correctly said Sarah, but then when I asked 何人（なに人）ですか？(Where are you from?) the transcription into kanji caused the なにじん(nanijin) to be interpreted as the most common way to read those kanji なんにん(nanninn). So she responded to the question "How many people are there?" with "There are 6 people in my office".

I don't know how easily fixable this is. Either context needs to be taken into account, or the original phonetic transcription should be kept underneath the kanji.
This depends on what we define by industrial revolution.

State owns a significant share of Engie, moreover because oil is a strategic resource, governments often have a right to intervene in corporate governance when it threatens national security.
Amazing read, really well written - prior to reading, it seemed odd to me that a simple PID insulin or sugar pump armed with a glucose sensor could not mimic a pancreas. I didn't realize there were so many variables. It still seems from my engineering mindset that a PID device should be able to do this, but I'm starting to understand why it's not so simple now.
I worked in oil and gas in a previous life. The absolute wildest people I've ever met are saturation divers - divers who live in pressurized chambers on ships for months at a time to avoid having to decompress after dives. Fantastic money but you need a few screws loose to handle the work.
