I would like to add one of my favorite mathematical "cookbooks" -- "Mathematical Methods in the Physical Sciences" by Mary Boas.

Bad Integrals? Tensor Analysis? Fancy functions and special polynomials? PDE tricks?

Boas has solutions!

Methods are practically explained and succinct. It's my favorite book to brush up on a old technique or learn some new methods.

Wolfram's Mathworld is also a good reference, but not as much of a learning tool.

Exactly. I ask that the applicability of Feynman’s lectures is not presented in absolutes - not always, not for everyone, not never.

But definitely sometimes for some. Including to start with.

They’re quite beautiful.
Im in Denver too. consumer products are up.

Cloud: we have large appEngine (2000 req/s at peak - it's <i>very</i> up and down spiking), functions, and heavy pubsub/biquery. Didn't notice any downtime or large errors.

Last time there was cloud downtime Google wouldn't give any credit because it was still under the SLA. Though we're really small fish a tiny gesture of good will would have felt nice.

Nice article. Missed one thing about PL1 that I think it got first and that you see nowadays in most languages (other than low-level languages like go and C) and most large programs -- a hierarchy of error types, blocks of code to catch errors (exceptions) according to type, and the ability to replace one error-handler with another temporarily within a narrower scope. Not to say that this is good, but it is what we've got.

Lifted millions out of poverty at the expense of millions of middle class American jobs. I believe globalization largely did not end up in the best interest of most Americans because the transfer of technology and manufacturing did not result in a new American ally, but rather a strategic competitor. For over a decade now we've seen a rift in the interests of the common people and the elites in the United States, which is why we've seen the resurgence of populism.

You can set up a backup Github? So you mean, you'd run like, an in-sync Gitea or Gitlab, and when there is an issue with Github your team and deployment methods (CI/etc) would automatically switch to that backup (temporarily or permanently)? That seems.. convoluted.

I feel like I'm repeating myself, but the advantage is being distributed. Distributed systems usually aim to be resistant to these types of issues. I'm a bit confused at your question. Are you asking why being distributed is good? Or are you asking why being distributed is good in this case?

If you're asking the former, I don't think this convo is in scope of explaining distributed vs centralized.

If you're asking the latter, why would this case be any different than any other case? You have a centralized entity and a while bunch of community and tooling built around it. Why wouldn't you prefer that out of control of a single entity?

The very argument against centralization is built into the foundation of Git itself. Yet you're asking why someone might not want centralization for the rest of the non-Git components[1]?

[1]: "non-Git components", While the source code is tracked via Git, I just mean the centralized entity your CI/CD/etc is hooked up to is it's own thing.

I want to address your points re Cuba and Venezuela.

I'm going to start with Venezuela since I am a Venezuelan-American and you might not like what my views are on the topic. First of all, I always assume good faith, even when it comes down to Sanders, unlike Michael Moore, for instance.

- Venezuela

Sanders expressed his support of Chavez in many of his writings. So, you might not consider him a Chavista, but he's definitely praised Chavez at least up to 2011 [1].

I know this is anecdotal, I visited Venezuela many times: 2005, 2008, 2009, 2011, 2013. Believe me, anyone with good faith could not have praised whatever was going down there in 2011. 2000? I can give you the benefit of the doubt. Chavez had only been in office for ~3 years by the time and hadn't shown what an awful dictator he was going to become.

- Cuba

Have you been to Cuba? Again, this is anecdotal, but nothing like first hand experience on a matter to make some people understand what the ugly reality is outside whatever some organization states on what the state of those countries are.

Trust me, you don't want to be in a Cuban hospital.

>> No need for the government to seize the means of production
> I do not believe Sanders proposes that.

Here's a video [2] where Chavez is seizing the means of production on national TV.

I find deeply sad when some Americans try to justify certain candidates who have supported awful governments, like Chavez's or Castro's.

It suffered from the curse of parenthesis.
It would help to know what background you have and what interests you/what you hope to get out of it. Did you have basic physics in undergrad?

Foundation can mean a lot of things. It can mean having a really solid grasp of how Newtonian mechanics is put together. It can mean having a solid grasp of doing experimental physics on classical systems. It can mean having a mathematical understanding of symplectic manifolds and quantization. It can mean replacing your naive physical model of motion in your hind brain with a learned, Newtonian model.

If you've never done any lab work, actually getting a stopwatch and conducting experiments with balls rolling down inclined planes and the like can be...eye opening.

You will need problems to work, otherwise anything you do is superficial. For example, here's a collection of elementary physics problems: https://archive.org/details/BukhovtsevEtAlProblemsInElementa... (The Russians were great about building this kind of collection.)

If you can give some more detail, it will help us direct you better.
A few weeks? Really? A major geopolitical shift the likes of which the world has never seen is going to occur in a few weeks?

This is real, but also not new (as you can tell from the name check on Flash, Silverlight and IE). They used to be called "supercookies", but that term has come to mean something else in the last few years.
+1. The Jackson book is notoriously difficult. I think Griffith's book might be better for a self-learner but, iirc, and I haven't read the book in more than 10 years now, he expects a pretty good understanding of applied calculus before you open the book, so read up on that! Best of luck with the studies OP.

Also, the look into the Feynman book QED once you have a little bit under your belt. Its a fun and pretty short read and there isn't much math at all. I also think its a fun thing to read while learning EM since it opens you mind up to the next subject down the line, QED.
It really depends on the culture. When I write code, I close all chat apps, and check them for notifications every 2-4 hours. Everyone who works with me knows it and understands the reasons behind it. They have my phone number in a case of a real emergency.

If you review the links in this article the only scientific paper that is linked says, no, there is no evidence it came from a lab. Every source except the paper linked is from other articles that are not science journals and are often opinion pieces. I call bullshit. Science Journal or GTFO.
Great. Comment stalking. That's the sign of a well balanced mind. Certainly not the behaviour of a detached zealot obsessed with shoehorning their personal dietary preferences into every conversation.

0.003% of Chinese citizens being millionaires doesn’t discredit my comment.

If only a subset of them were the ones buying the millions of trafficked Pangolins and civets and whatever else carries CoV, then that’d be great progress as a starting point.

Then for the wealthy you can make it a big social stigma to purchase them, especially after it brought the worlds economy to a halt... instead of doing the complete opposite where authorities are promoting it. Chinese authorities are well versed in influencing social stigmas and public shaming, which is a big deal in a country where ‘saving face’ often outranks reality.

After that you could focus on culling the wild populations that often get released in atypical habitats as a side-effect of poaching http://www.bbc.com/earth/story/20161006-pangolins-are-the-wo...
Honest question, are you speaking from experience? We run PCRs at our company for our vaccine research and having to run them back-to-back day-in-day out, without any manual errors, is going to be super stressful for any lab. Not to mention the costs of training healthcare personnel on how to run a PCR.
I was interested in this too as someone who's worked in web apps the last 8-10 years and was super inspired by the SpaceX Falcon Heavy landing (science fiction is now science fact!) I looked into graduate programs, especially those online, and found the JHU Space Systems Engineering program. The prerequisites for THAT program are a year of college Calculus and a year of college Physics. I'm currently taking that, "year", which is really just Physics I and II and Calculus I and II at Thomas Edison State University. They've been doing distance learning for decades.

The courses aren't super cheap, they're around $2,000 each, but having classmates, a mentor, deadlines, and a legit program to structure my learning around has been so helpful. Not to mention that my grades are legit for pre-reqs if I do want to go the full grad school route. I'm almost done with the I level courses and started the II level courses 2/3 of the way through the I.

I think a lot of people on here might say my approach is kind of basic (I see people recommending working differential equations or something to start), but I've found it really enlightening to start from the very beginning and things are starting to get challenging as I get into the second level, especially with Calculus. Maybe if you just looked up Physics I and II and Calc I and II curriculums, and got the textbooks (Conceptual Physics by Paul G Hewitt and Calculus: Early Transcendentals by Robert Smith) you could do a lot of the same exercises.

Hope that's helpful!

> No, flu vaccines cannot cause flu illness. Flu vaccines given with a needle (i.e., flu shots) are currently made in two ways: the vaccine is made either with a) flu viruses that have been ‘inactivated’ (killed) and that therefore are not infectious, or b) using only a single gene from a flu virus (as opposed to the full virus) in order to produce an immune response without causing infection. This is the case for recombinant influenza vaccines.
I've said it before, but the problem with having only a hundred words is that they are the hardest one hundred words in any languages. To a foreign learner, easy words are hard, and hard words are easy.

To someone learning English as a foreign language, "banish" is easy to understand: it has just one meaning, so once you memorize it, you can recognize it whenever it's used.

"Turn out", on the other hand, has half a dozen meanings and you have to rely on context.

In the extreme case, imagine explaining the word "the" to someone whose native language doesn't have an article.
> based on Germany’s numbers, which are more fully accounting for those with mild symptoms

It's only "5x" the flu (you say so, I didn't look it up) BECAUSE everything is locked down. If we continued to live and work as usual hospitals would be overcrowded (they already are in italy, spain and some parts of france), which means a bicycle accident, a car crash, a bad fall = you'd die because no one could take care of you. In Italy they had to call the army to get more body bags and more people to carry the dead out, NY is already running out of space to store dead people.

You can't just look at low numbers due to aggressive lock downs, project them in your imaginary world and draw conclusions while ignoring all the side effects.
Maybe.

I don’t grok how one can write 100+ ceremony loc to filter a todo by a “.completed” flag and still think it is okay to burn a barrel of cash and half a day to implement that [1]. I also don’t grok how this approach can work any “faster“ or battery/memory-saving or be used sanely in apps slightly bigger than my generic todolist. It is both millions of dollars of bootstraps, boilerplates and learning curves for what supposed to be a simple logic.

Maybe I’m wrong, but it feels almost like a conspiracy to justify 6.5-figure contracts and nothing more. And the rest of developers just rationalizing around this phenomenon.

Not having a way for web apps to communicate a call to action dramatically reduces engagement with this feature, no doubt. The only way I can see this from Apple's side is they see it as a feature for Safari users, not from the platform side for the web.

From Apple's standpoint, when you put yourself on the user's homescreen, that is a deep connection between that app and the user. Apple spends billions in each finding new ways to enhance and enrich that connection. IMO, their _belief_ is that building a native app to take advantage of all these rich and engaging ways is the best way to build deep connections with your (developer's) users.

Being an icon on the user's home screen is where deep connection begins, not ends. You might add a today widget, you might want to send notifications, you might want to add AR experiences. You might want a Tablet experience and allow hand off between these devices. Apple is invested in becoming a deep level of importance in a user's life. They want to share as large of surface area with 3rd party developers as they can. It would be irresponsible to promote an API that made developers have to start from scratch when they decide they want to go deeper.
Completely agree. ASCII graphics were completely fine, if not desirable. I loved playing DF but I also hated it at the same time because of the inconsistent UI. wasd vs. ijkl vs +- vs arrows vs ... almost nothing made sense to me until reading the manual. Granted, the game is fun enough that I always read the manual, but a good UI is intuitive UI. I hope this new effort fixes more than just graphics. I can't care less about ASCII vs pixel graphics, but UX needed to be improved imho.

China Is Now Blaming a Lone U.S. Cyclist for Coronavirus
It's hard to take you seriously when you take a range given by the CDC (38,000,000 – 54,000,000) and cherry-pick it as a specific figure that makes your position look stronger. You're arguing in bad faith.

Even according to the figures you've given from the CDC, the flu has a 0.1% death rate, which is nowhere near the 1.4% death rate COVID-19 currently has in the US.

No one is trivializing the flu, but it's silly to say we should relax w.r.t. COVID-19 because we're used to the flu. At a minimum it kills TEN TIMES as many infected people as the regular flu, even without considering vaccines.

Influenza is chump change compared to COVID-19.

This wave of computer-literacy programming was actually started by a series from the BBC's commercially-funded rival ITV, Christoper Evans' The Mighty Micro.http://www.retro-now.com/the-mighty-micro-itvs-forgotten-com... https://www.youtube.com/playlist?list=PLqrLFTwrYemNYgb-hPXd3... (Evans also appears as a guest in the CLP's The Silicon Factor. https://clp.bbcrewind.co.uk/b5047fb21312089c95fdf482cda3c697)

I wonder if anyone has chased down people who remember Dick Brodner's circa-1980 home-automation setup in his Chicago house https://clp.bbcrewind.co.uk/e0417b82d1c1a84345852bf21916073e , or found out what became of it or if anything remains of it?
1. China’s early failures were quickly remedied. They enacted a massively costly economic shutdown early, and bought the west weeks or months. What did we do with that bought time? We wasted it by denying the threat, failing to stockpile, and ultimately doing the exact same thing China did (trying to suppress news of it from the top). At least in the US a select few Republicans were able to profit off this, so I guess they can thank China for their generosity.
2) China built two hospitals in a week, and nearly instantaneously shifted a significant portion of their industry to making medical supplies. Thousands of Americans will die because the US President won’t invoke the defense production act. US does adapt, but it does so too slowly to solve the problem.

China has proven themselves massively resilient. Right now, they’re worried about reimporting cases from Europe and have covid largely under control. It would have been better to not get out of hand in the first place, but they’re the only country that’s demonstrated an ability to work themselves back out of the crisis once it’s unfolded.

Already, colleagues in China are returning to work, and I’ll be out of the office likely until May. China gave us weeks if not months of warning that we ignored, so it’s a little frustrating to see Americans and Europeans finger point when ultimately we’re responsible for our own shit.

If you look at China’s trajectory over the past ~15 years, it is obvious that the 21st century is theirs for the taking, as the 20th was for the US.

AI Deciphers Persian Cuneiform Tablets from 25 Centuries Ago
Which ones? Last time I looked that list couldn't have included glibc, which while nominally supporting it had several, long-standing thread race bugs. The nexus of dynamic library loading and threading is a hot-spot for bugs in glibc.[1]

Excluding an interface is better than providing a buggy one, IMO.

[1] What glibc needs to do is finally merge libpthread into libc proper. The amount of stub functions, conditional logic, mutex reimplementation, and other chicanery glibc implements in an attempt to support runtime loading of libpthread[2] makes the code extremely difficult to navigate and debug. Which IME goes a long way toward explaining why there are years of unfixed races in glibc.

[2] By runtime I mean loading libpthread as a dependency of a shared library where the main binary wasn't linked against libpthread.
> I wonder how many people feel they have the option to not take back a job?

This is exactly why social safety nets are limited in the US. A social safety net drives up wages. Workers no longer rely upon a job to the degree they did before.

So it raises wages and raises taxes, which raise cost for everyone else. It forces managers to actually pay a living wage and take care of employees, which hurts them because they can't treat people like shit to get good numbers to show their managers.
The problems from undergrad (I think we used Purcell) were virtually identical. Jackson's book had problems which were more algebraically/computationally difficult, but otherwise; it was basically the same thing. It's a well written classic; no reason to use the book with slightly wimpier problems.

He asked me how to learn physics; not how to learn some wimpy undergrad physics which doesn't give you the big picture. Hindsight my undergrad E&M book was a waste of time, and we should have just used Jackson. I still have Jackson (and Eyges) on my shelf; the undergrad book was recycled years ago.
