>it's really tough choosing component values that don't ring like a bell, a loud bell, at pretty high frequencies

That doesn't sound right to me. It's not really about the component values. It's about the parasitics and the edge rates that can ring those parasitics. The main LC elements are not usually the problem (especially at high frequencies).

> for simulations

You cannot simulate any SMPS for EMC reasons without including the layout. Full stop, do not pass Go, etc. You can simulate for functionality and you can avoid some well-known traps, but you'll never be able to be confident without the layout included. Never.

> run the input voltage as high as feasable

Usually you want your duty cycle around 50%. Higher input voltages will push that down, which is usually a bad thing and requires special measures to compensate. And switch capacitances are rarely a major problem below line voltages, so you don't get much return on it either.

What, exactly, are you trying to do?

(Disclaimer: professional EE but not a power guy. I do little SMPS stuff up to 24V all the time though, especially low-noise analog supplies.)
Roads tend to have a speed where people feel comfortable. In theory, road engineers design roadways to match the desired speed. In practice, that doesn’t always happen. Even worse, cities/towns have been known to lower the speed limit to drive revenue.

Edit, some links:

https://www.strongtowns.org/journal/2021/8/6/the-key-to-slow...

Usually, when people talk about the topic, they’re trying to calm local traffic. But the concept applies to highways where speed limits can be pretty arbitrary. Plenty of interstate where 80+mph feels safe, but is posted at 55 or 65.
You are certainly doing something wrong - I'm serving multiple wordpress and static pages from a former passively heated thin client with a Celeron N3010. The only diff is AES-NI compared to core2duo.

2nd this. Sounds very interesting.
I agree with everything you said here; I particularly agree with the part where you say that after knowing Scheme and Haskell everything else becomes easy and boring. Does it ever. Makes me question why I got into programming now that I see the bigger picture of what I have been diligently trying to master for over 15 years.

To the beginner I'd say: study Scheme and Haskell. Understand them. Once you do, look at other languages. Everything should be familiar. Now you have to decide if you want to spend your professional life always learning different ways to do the same few things there are to do that you learned from Scheme. YMMV but yes it gets boring and yes it will burn you out.
What kind of a short-range nuke is going to hit Washington, DC? If it was installed in Seoul, South Korea then maybe, but not DC. There is already a large system in place to detect long-range ICBMs.
Are you talking about compiling R from source, including all dependencies and high-performance BLAS, LAPACK, FFT, ARPACK, etc. libraries? If not, you are comparing apples to oranges.
I disagree. Public opinion polls clearly show that the younger generation is more intolerant of the NSA mass surveillance[0][1], for example.

Sometimes the difference can be startling:

Once again, there was a significant relationship between age group and support for monitoring everyone’s online activity. Only 15% of Canadians aged 18 to 29 believed that the Canadian government should monitor online activities if officials say it might prevent future terrorist attacks compared with 34% of those aged 30 to 44 and 43% for those aged 45 to 59.[2]

That's almost a three fold difference between the 18 to 29 group and the 45 to 59 group.

The fastest way to fix a problem is to tell the developers. Not get the authorities involved. I agree, it's negligent but at least give people the opportunity to fix their mistakes, and maybe even inform their customers. I suppose we should shut down every business that makes a mistake with customer information. You can therefore shut down Microsoft, Ebay and all the other organisations that have had data breaches in recent years due to negligence.

If, like me, you haven't read Neuromancer in 20 years, from wiki:
"A street gang named the "Panther Moderns" is hired to create a simulated terrorist attack on Sense/Net. The diversion allows Molly to penetrate the building and steal Dixie's ROM."

I'm not really seeing why this (or the fedora squad) is something to be welcomed.
This documentary looks fantastic. I'm looking forward to watching this and Citizen Four.

A note to anyone who might be reading this before the article, don't read it all as it contains spoilers from the documentary.
I highly recommend this book. The first practical lesson, as I recall, has you short-circuit a battery and destroy an LED. It's great to learn the limits of typical components this way, and it takes away the fear of breaking stuff. It's written simple enough to be followed by a child, but I had a blast going through it as a physics grad student who knew electrodynamics and very little electronics.

The first two editions had quite a few errata, but there is an online page for them:

Compare that to something like soul cycle at ~$30 per class or Orange theory at ~$200/mo/person
I figured HN probably ran on an old desktop tower under somebody's desk, with a post-it note on it that says "DO NOT REBOOT!!!!"
Seems redundant to me. This tweet literally links to the same Apple press release and a way to get notified by Stripe when it's available. Doesn't really seem to add much new context besides "Lookit, it's Stripe."
What's the goal? Does your grandma want to start a blog and you're talking about hosting the HTML from that folder, or do you want to be able to access the folder to read/write files, or something else?
That's the optimistic view, yes. But if they aren't truly the first company to start laying claim to mineral deposits? That's the nature of investment.

If I set up a company tomorrow claiming to have solved cold fusion, I'd argue it was beyond undervalued. Until I deliver on that promise an investment would remain a risk. Not that I wish to demean what SpaceX have done so far - it's fantastic. But rocket science is, well, rocket science. And a lot can go wrong.
Even if it were the case, you can't argue around China's policies with legalese. They have much more free reign to do what they want than other governments.
Some people in Germany call it 'Klammeraffe', which would roughly translate as 'an ape that clings to something' or 'spider monkey'.

"Hammerbacher looked around Silicon Valley at companies like his own, Google (GOOG), and Twitter, and saw his peers wasting their talents. "The best minds of my generation are thinking about how to make people click ads," he says. 'That sucks.'"

I loved this quote, I also had a similar experience. In past I had an internship in a similar role and pursued few projects on mining communities in large social networks. However luckily I got an amazing opportunity of working at med school/hospital affiliated with my university. I now apply similar algorithms, but now I help radiologists and physicians.

Lets hope that in future the methods that are developed for optimizing ad clicks could probably be useful in some other field.
E.g. how IBM is now planning to use Watson in healthcare. My guess is that a lot of algorithm used in developing Watson, were developed for ranking Ads. Closer home, I use a 55 node Hadoop cluster for processing 19 Million annotated PubMed abstracts.
1. I never said they moved the entire code base. What would be the point of moving the entire code base anyway? The reason why they moved search to Java is simply because Java scales better than Ruby when faced with heavy traffic.

Well, the release date is TODAY.

The first showing here on the east coast isn't for another three hours, if you want to go to a film at 11 o'clock in the morning on a weekday.

I'd say it's a pretty fair bet that the ratings are coming from people who haven't seen the movie.
It was not the high-quality of the "a" on the right that was exaggerated, it was the low quality of the one on the left.

The "a" on the right is fine, it is there to represent the kind of image in which you no longer are able to detect pixillation, going above of the supposed 300dpi limit, like what would happen on the iPhone4. On the other hand, presenting on the left an "a" with half the quality of the one on the right would probably be too difficult for people to spot the difference.

If they were fair on that slide, it probably would be interesting to analyze if people would really notice the difference or if they would just pretend they did (http://en.wikipedia.org/wiki/The_Emperors_New_Clothes). Sure thing, it would not have that much of an impact, at least until all of those people get the chance of having the new iPhone in their hands.
how did you decrease 7 MB to 0.5 MB? only by removing unneeded modules?
Why would there be crashes? The running apps will keep their already loaded binary until they're restarted.

Maybe there'll be some bugs in handling shared on-disk resources (cache, and maybe something else?), but I doubt that those parts change very often. That would be a reasonable reason to require a reboot, but unless those parts actually change it should be avoided.
Slip coaches manage the drop-off, but not the pick-up.
It makes intuitive sense that the method with the deepest emotional impact would also have the greatest psychological effect.
It just doesn't work that way. If Apple allows it and it becomes at all popular, they are stuck in a situation where they either need to support it directly or deal with the predictable outrage from the blogosphere when iTunes X.Y breaks Pre syncing because Palm/HP hasn't updated their hacks yet, or worse they have to deal with people not upgrading iTunes until Palm/HP does update their hacks.

All because Palm would rather piggy back on iTunes than write their own playlist manager. Oh, but of course, it's Apple slapping users in the face, those dicks, how dare they.

Yeah, that was a bit snarky, but come on...

Jeez, this is horrible blog spam. It doesn't matter that this is TechCrunch.

The number 1 article on HN right now links the original blogpost, and the comments cover the non-insight TC provides. The comments even copy/paste the original blog, if that's what you want. That seems to be the main service being provided by TC here.

I'm not technical but there should be an easy way.

In what sense are you using the word 'should'?

Technically, if FireFox or Evernote holds it's files "open" or "in use" then it doesn't make sense for other programs to try to use them or to act as if they are going to be in any predictable state.

If you mean should in the sense that the computer industry should have solved this problem, then it is solved for some classes of program - always on database servers still need backups, so you instruct them to put the database in a consistent state, take a copy, and then instruct them to carry on. Previously, you would shut them down, take a backup, then restart them.

But to use that solution, both the database and the backup system have to be extended to support this, and to have it on a normal user system, every program would have to have a way to accept that kind of instruction from outside, and things like Evernote and FireFox haven't been designed with that in mind.

There could have been an easy way, except there wasn't one built in historically and now it's not easy to add one, so there isn't an easy way and wont be in the near future, even though it would be nice if there was. Your best hope is a FireFox plugin and an Evernote update if enough people ask them.

There's a phrase "Talking out of both sides of your mouth." He said what he believed the urging of politicans, media and oppositional citizens wanted by saying "go home" while continuing to say what his base wanted to hear - "we won in a landslide and it was stolen."

Each side could choose to only hear what they want, or recognize it for the manipulation it is. We know what his followers will do - hear what they want to hear. We know what his opposition will do - hear it for the manipulation it is. Therefore we can conclude that it was not a genuine urging of his followers to actually give up and leave.
That's a false equivalence, because the words of the president directly incited violence and resulted in an angry mob storming the capitol building.

I would hope that if a left-leaning politician did the same that the same precedent would be applied.

I'd still be opposed to it on principle because no matter what protections and limitations are in place initially, if they're put in place by a centralized (aka corruptible) organization, they can just as easily be replaced or removed. Even if there is evidence that such a program would save many lives (and arguably such evidence is starting to come about) it still remains to be seen whether those lives saved even out versus the amount of lives that would be upended in the future because the "privacy line" has been redrawn. All change is incremental, and we don't know what an incremental change away from privacy as a basic right to be respected no matter what could lead to as a next step.

It's entirely possible that even with all these considerations, a democratic society still chooses to implement such a program. In such a situation I still think it's necessary for someone like me to stick to privacy as a principle even if only for the sake of philosophical discussion and keep parroting: "We're on a slippery slope!"

All of these clouds are spawned out of already-large tech companies, many of whom have built a massive technical infrastructure to support their original businesses, then turn those resources into services to rent out in the form of cloud

This is a myth that’s been disputed several times by high ranking Amazon officials. Amazon never turned their internal infrastructure into AWS. It was always a completely separate initiative. Amazon was not on AWS for years.

Google also only uses GCP for a few internal services.
