The SR-71 cruised at Mach 3.2. Scramjets have been demonstrated to do Mach >5, and theoretically might be capable of something between Mach 17 to Mach 25(!!!)

Scramjets do need air, although something to consider is that the faster you go, the more air you get. So at high altitudes with very thin air, you can go faster to get more air. In fact you have to go faster (true airspeed) in thin air anyways even if your brought along liquid oxygen for your engine, because as the air thins your stall speed will go up.

The whole thing is a complicated system of equations. Engine capabilities and/or critical mach number (for planes designed for subsonic flight, like the U-2) of the airframe set an upper limit on how fast you can go. Air density decreases with altitude, increasing the stall speed (according to true airspeed, not indicated airspeed.) But for a given true airspeed, with increased altitude the temperature of the air drops, consequently dropping the speed of sound, which reduces the mach number. In subsonic planes as altitude goes up the stall speed and critical mach number eventually pass each other, beyond which your plane can no longer fly. The point of that intersection is known as the 'coffin corner'. In planes designed for supersonic flight passing the critical mach number isn't a problem, but eventually you'll reach a point where the drag on the aircraft is so great that the engines simply don't have enough power to overcome it. Increasing altitude reduces drag as the air gets thinner, but that only works for so long. Air speed inside the engines needs to be considered too. The airspeed past the turbine blades needs to be such that you won't get compressor stall. When you discard the turbine requirement, that's where things start to get interesting. A ramjet has no turbines, it compresses the air using the intake geometry. At full speed the SR-71 was actually producing most of it's thrust with a ramjet effect, most of the air going into the engines was not going through the turbines. The difference between a ramjet and a scramjet is that in a ramjet, the air inside the engine becomes subsonic again for the burn, but in a scramjet the air inside the engine remains supersonic. Scramjets could go really fast.
Signal now uses the Android hardware keystore such that you cannot use a root app like TiBackup to move the Signal data around anymore. Instead you have to use Signal's built-in backup and then place the backup on the new phone and setup Signal again (generating a new ID key).
Wow! I guess both sides are the same in every situation in which two groups disagree, and there are no right answers to anything. I'm shocked it was so easy to prove this, once and for all!

It sure would be inconvenient if anyone pulled back the curtain on this intentionally-vague comment to show that you're equating "Nazis" with "People who disagree with Nazis"!
Office Depot, Staples, Office Max : These stores need to die. I’ve never felt worse by stepping into these stores without some clerk coming up to me about up selling this kind a bullshit.

They’re old relics that need to die like Sears did. They’re not innovating, they’re getting desperate as we’ve seen RadioShack in early 2000’s leading up to its bankruptcy in 2015.

Furthermore, they pay poorly to their employees, and there is a whole bunch of toxicity in there. Best Buy was on its way on the same path but they’ve saved themselves by a narrow margin. I still despise their “Geek Squad”. They take advantage of uninformed consumers and it’s sleezy. It makes me angry just thinking about it.

The leaders and executives that run these businesses are completely and utterly out of touch with their core business values, innovation and having a vision for the company. Spineless bozos.
I never understood how you could sign away a constitutional right like that.

It seems like any aspect of employment could be discussed under the first amendment as that corporate charter was granted by the government and the civil court that might enforce the clause is also run by the government.

Obviously I'm not a lawyer because I have no idea how this shit is even legal.
I've tried those out and they still often don't seem to contain music I enjoy. When I start back into a job over the summer where I am listening to Spotify more at work maybe these will start to become better, but currently the majority of what I have been using for Spotify is working out. So in some sense I get why my recommendations are that however that is also the time when I am less concerned about "good music" and stuff that matches my taste, and more just concerned about higher intensity up-beat music.

Sometimes I'll have a couple hour car ride, or be relaxing at home and try and use Spotify to find something and just never seem to find a good way to find something quick. I'm shit when it comes to knowing what I like and what kinds of genres I'm into and that's why a radio style suggestion thing is good for me, it's just been broken by my heavy workout usage.

I've actually as an alternative sometimes been using Google Music instead and been quite happy. I just don't like the selection and do prefer Spotify all around.
> you could have been getting paid a lot more in that time

I'm sure you are familiar with the concept of fuckyou money. Its a different number for different people.

Say that number is 5.
I will give you many examples below.
Every example is a real living person.
I personally know every one of these people.

(enterprise programmer in stodgy bank in usa)
1 + 1 + 1 + 1 + 1 = 5

(enterprise programmer in stodgy bank in poor country)
0.5 + 0.5 + 0.5 + ... + 0.5 = 5

( steady progress in startup until faang acquired it)
0.5 + 0.8 + 1.2 + 1.2 + 1.3 + 6 > 5

( many failed startups in valley until 1 success)
0.5 + 0.8 + -2 + 0.5 + 0.7 + -2 + 0.5 + 20 >> 5

( phd student whose invention was purchased by salesforce )
0.1 + 0.1 + 0.1 + 0.1 + 0.1 + 0.1 + 15 >> 5

( phd student who ended up in fang )
0.1 + 0.1 + 0.1 + 0.1 + 0.1 + 0.1 + 2 + 3 > 5

etc.
I don't think it's unrelated. Despite the name, WASM isn't really a "web technology" - it's a sandbox technology and a compile-once-run-everywhere technology, and there has always been demand for that outside the web, even before the web existed. It might be that the web is what created enough demand for it to happen in the end, but what do we care?

The problem with JS was never that it's a web technology. It's that it's a bad technology that happened to be in the wrong place at the wrong time to get a first mover advantage.

Cross platform is in no way new. There are already plenty of ways for native devs to target multiple platforms at once if that's required.
I work on the client-side javascript SDK for PayPal (documented at https://developer.paypal.com/docs/checkout/).

We took Michael's feedback from his original article at https://fman.io/blog/paypal-for-saas-99-problems/ very seriously. We're not all of the way there yet; but if anyone has any remaining concerns about the integration, I'd be glad to take them onboard!
> these platforms are intertwined enough into society they are blurring the lines between optional service customers can switch off of, and global-scale utilities that are necessary to operate in society.

That supposed blurring is illusory. There are no impactful consequences for not using Facebook; it is wholly unimportant and an entirely superficial distraction, in fact, less use of Facebook correlates positively with mental health. You most certainly do not need Facebook to operate in society.
The Auger detector is one of the coolest detectors I've seen. I had to do a report on it in grad school. My favorite factoid is that it is the size of Rhode Island. Also, at the time, it had seen particles in the 10s of EeV range, which is also known as a Joule. The same kinetic energy as a 2 kg object traveling ~1 m/s. In ONE SINGLE PARTICLE.

I love physics.

That's assuming that the well-paid and comfortable engineers decided on and implemented the patch.
>It already festers somewhere else

excluding people from a conversation doesn't help them learn why/how they think is wrong.. those "hidden" places that let the wrongthink fester only create more actions brought by wrongthink (guess what they talk about? wrongthink).

i dont understand the logic of removing someones ability to converse if they dont understand why they're wrong.. they cant ask questions

"You have enough money you live the rest of your life in idle luxury. You could just go to the beach and never come back. If I had your money, that's what I would do. Why the heck are you still working?"

A wordy, trying-to-be-cute way of saying "What motivates you to keep working?" or "Why do you keep working instead of retiring?" which is a pretty good question.

"Will you share slides from the last board meeting?"

A bit presumptuous maybe, but not quite into the realm of arrogance. I would verbally summarize the slides.

"Where do you see yourself in 5 years?"

Nothing arrogant about this one; a CEO should have a 5-year plan at least. Although this particular way of asking it has been used verbatim enough times since I first heard it in the 80s, that it now shuts down my mind immediately due to its blandly mind-numbing cliché quality. Which doesn't speak to the candidate's amazing creativity. Don't ask it this way if you're sitting with a Gen-Xer probably.

"When I leave here in 2-3 years, will it be because of the people, or because I haven't gotten a raise and/or promotion?"

I mean, you tell me. Are you more "I have a terrible personality and poor social skills" or are you more "I get childishly petulant when I don't get promotions and raises I think I deserve?" Both these things are within your control... and so is your exit from the company for that matter. If you were mature enough to take responsibility that is. Terrible question, don't ever say this. It conveys four negative things about you, all of which I would assume are true.

"What keeps you up at night?"

The question is again trying to be all folksy and cute bygoshdarn bygolly, but at its heart it's a pretty good question. In other words right now what's your biggest obstacle / thing you're worried about / thing that's giving you a pain. At work mind you... not your personal life!

Unfortunately there are some issues with this. Here is what that page notes:

> Note: Anything you play privately may still factor into some of the personalized mixes we make for you (but not Discover Weekly).

So it really only would fix the discover weekly partially. But the issue is that they still see that I have workout playlists that I am following and using a lot and still factor that in. And I've found that it can be quite tedious everytime I open Spotify at the gym to have to go in the settings, scroll down a bunch, and then turn it on. It stays on for 6 hours. I'd love if that feature even simply had an option to turn on based on my location.

That would be sometimes 5 times a week everytime I'm at the gym I have to find that option in the settings and turn it on, and then also turn it off if I don't want to have it stay on for the next 6 hours. Not to mention I already have to spend time in Spotify to find the playlist I want to listen to for that day at the gym. So it just feels like a lot of manual work I have to do in the app for a small gain.

>The other half of USA high schools? They don't even offer a Calculus course of any kind [1]

That's a bit misleading. There are many districts where one school serves as a magnet school where anyone interested in taking more advanced classes can go. So yes while it may be true that half of all schools don't offer calculus--far less than half of all students can't readily take calculus.

> It often makes me think about such diagnoses and how insular/individualistic they can often be, and how powerless they can leave one feeling when diagnosed.

Powerlessness was the furthest thing from my mind when I was diagnosed. Having a classification means that you have options and measures and an implicit community. I always suspected I was on the spectrum, but the diagnosis gave me access to professionals who specialise in these conditions.

> If you're 'on the spectrum' but your symptoms are mediated by partner/family/culture, are you still on the spectrum?

Yes, 100% yes, completely, utterly yes. Having coping strategies are great. Having the "tools in the toolbelt" is completely necessary and being able to "pass" is critical. But ASD is a problem with managing stimulation and all the behavioural controls in the world aren't going to do squat to your frustrations, mood or exhaustion levels if you spend the day with overloaded inputs.
I'm an American that has been working at an American company in China for the last year. I'm ethnically Chinese and can speak okay (HSK5 - HSK6) Chinese.

Overall, it's been a negative experience but I don't regret at least giving it a shot.

-Even in multinational companies people are in the office for much longer hours than in the west. However, a lot of that time is on wechat, super long lunches and who knows what.
-My compensation is a bit more than half as much I was making in the US but my taxes and living costs are much much lower. I can save almost as much as I used to. If you get a job in China, make sure to really understand your pay structure and tax implication. Your taxes could either be super high or super low depending on the structure.
-Pollution is awful. It's really oppressive some days and you just don't want to go outside.
-Chinese ability is a must. Basically all my technical discussions are in Chinese.
-The 差不多 (good enough) mentality is exhausting sometimes. Even in tier 1 cities, everything is falling apart and looks like crap up close.
-I have a mix of foreigner and Chinese friends. When I first came here, I was super insistent on only hanging out with Chinese people to get the "real experience" but realistically as a westerner there is too much of a culture gap. Most Chinese people that I've met are very very focused on work and their income.
-Chinese people are pretty nice individually when you get to know them, but it's a different story in public. Cutting in line, shoving their way, watching shows full volume on their phone in the subway, riding their bikes into you, etc...
-Phone usage is crazy here. It seems like nearly everyone is glued to their phones at all times.
-Dating is really easy (if you're a man). I haven't heard this mentioned in this thread yet, but it is a big reason why a lot of expats move to China. However, I would tread very carefully. I wouldn't recommend starting a serious relationship here unless you're in love with China and are in it for the long haul. Also, casual dating isn't very common here so girls get attached very quickly. If you're planning on just dating around, you'll feel awful eventually unless you're a sociopath.
-Red tape everywhere. It seems difficult to do nearly everything, especially if you're a foreigner.

I definitely wouldn't live in China for the long term, but it's been a pretty interesting experience. Do it for a year or two for the experience and then GTFO.
It blended very quickly from the start, but the claims about "gaming journalism" while hallow as far as their actual activity, was IMO a semi legitimate claim as far as some of the initial outrage..... but really it moved on quickly and didn't matter.
Regrettably, that's exactly one of the use cases.
100% agree. I disabled YouTube's history just so that it didn't give me weird recommendations. Maybe when browsing reddit I'd watch a weird video or two, or look up something a bit niche or different and suddenly YouTube for the next while thinks that is all I am into.
> Throughout most of my career, my PhD has felt like a liability. Especially when I've sought out a non-research-oriented position. Employers seem skeptical that I might rather spend my day coding a product I believe in, rather than solving esoteric research problems.

I've had this as well along with comments like "academics are bad at X", "academics tend to write code in way Y", "academics can only write prototypes and not production code", "I'm self-taught and never saw the point of University because..." etc.

Generalisations like this are really dumb.
A tiny minority... who would've done it anyway even without Facebook.
The only reason I've had to step foot in an Office Depot in the last 5 years is to drop off shipments. It's the closest FedEx and USPS drop-off location to me. Even then, I always try to have my items boxed and labelled before I go in so all I have to do is drop them off. I make a beeline for the back of the store, leave my items with the person, and politely say I don't need a drop-off receipt. Then I book it back to the front of the store and get the hell out.
I don't understand this... If I as an individual did the same actions, I would be charged with fraud. I might even serve time in prison for it.

In this company, someone up the chain of command knew they were doing this. Someone at some point was presented with "we'll give them fake scan results to upsell our services" and said "yes".

Why is that person not being charged with fraud, just like I would have been? What makes it just a fine and a slap in the wrist just because they're a big company?
Well at least we acknowledged there's some utility.

Now consider that mobile devices are different as well..

That is a comment I would put in frame as one of the rare comment where he use a negative adjective about Apple's products.
I was trying to find an article I read years ago, about how unsuited the supersonic fighter jets are for air support of ground operations. The main contentions were:

1. Modern jets need long runways (aircraft carrier slingshot notwithstanding) so anytime troops were calling in air support, a supersonic f16 would fly for an hour, have enough fuel for a couple of bombing runs before having to fly back to the closest large airport, compared to what the troops really wanted, a super tucano turboprop, which can take off from the dirt airstrips available anywhere in the country.

2. Modern jets, with their stunning array of passive and active sensors, encourage an eyes-off approach to dropping bombs : pilots can only trust their data, they are not close enough to the ground to recognize who's friendly and who's not.

Alluded in my sibling comment, A10 warthogs would have been perfect for these missions -- I don't know where the unwillingness to fund them comes from. Googling now reveals that Super Tucano turboprops are now being delivered to the afghan airfoce, since that's what you actually need to fight small arms battles in the remote regions of the country.

Closest thing I found was 2015, detailing why modern technology doesn't win the war, 'low and slow' can be a better game plan:

One of the early Foscam pan-tilt-zoom IR cameras? Your dad did better than I did. I liked the hardware, for the price point, and wasn't aware of alternative firmware. I ended up putting it on its own LAN with an old OpenWrt router, and kludging simple motion detection with a little program that ran on the router. (Script pulled frames from the camera with some HTTP interface using wget or curl, and used ImageMagick for the hard part.)
Keep in mind they were trying to convey the concept of sending a document electronically to the 1993 public. "Fax" is an easy widely understood stand-in for that even if we're not literally faxing today.
Wrong. It's a deliberate attempt to language engineer the idea that loving your country is bad. This is not new, the power structures that benefit from centralization (correctly) see national sovereignty as an obstacle.

Note how you will never hear the term "ethnic supremacists" used by conventional media. It's too accurate and does not push the borderless agenda.

Hmm, maybe we could have a "housing credit" market system. For every office building with n workers, require housing for some % of n within the local area. Then the credits would be priced according to the imbalance between residential and commercial construction. Excess housing around? (Hah.) Well the residential builders will have to pay the commercial builders!

I think that was the hope, but reality has set in and the lifetime of the A-10 has been extended.

I mean, why not? There is no current or planned plane as capable or as survivable as the A-10. F-35? Single engine, inline. Take that out and instant eject. Warthog was designed to lose an engine, even let it burn off and make it home. Control surfaces have mechanical backups. Not to mention the titanium tub protecting the pilot. And the cannon? Oh, the cannon. Can an F-35 take out a T-72 or T-80 on cannons alone? Doubtful.

A-10 is one of my favorite warplanes. Design was basically: here's this cannon, build a plane around it.
It won't factor in songs when making the discover weekly that were listened to in private mode, however the daily ones it doesn't matter for.

It's also a bit annoying to have to everytime I go to the gym not only have to find what I want to listen to, but also remember to go into the settings, scroll down, and turn it on, and make sure to turn it off in case I don't want it to stay private for the next 6 hours.

I wish it turned on based on location. Hell even if there was some intent or way I could trigger that to turn on/off from Tasker I could automate it myself :P.

I'm really bad at finding new music or just music to enjoy in general that I'd like and it's a huge annoyance to have shitty suggestions. Lately I don't even use Spotify much and have been considering just cancelling it.
