You need a LOT of fuel to make a spacecraft go in the reverse orbit. A LOT!!! To make hard turns the satellites use the gravity of another planet.

Also, the mass of biggest satellite we can launch now is only about a hundred tonnes (less than a boing 747), if it goes to a low orbit and it is much smaller if it has to go higher. With a back of the envelope calculation, you can store about 6 million batteries there. For comparison, the population of New York is 8 millions, so you can give them less than a battery to each one of them.

And increasing the mass of the satellite or the fuel amount, makes the fuel in the launching rocket much much much bigger. https://en.wikipedia.org/wiki/Tsiolkovsky_rocket_equation

Perhaps you can try to gain some intuitive idea about satellites playing the Kerbal Space Program game: https://kerbalspaceprogram.com/ The simulation is not totally accurate, but it's good enough and there are some mods to increase realism later.

(It's also not easy to store the energy for 6 months. Try storing a charged rechargeable battery for 6 month and using it.)

All other stories are sad, but this one is ironically funny.
An ex-Amazon engineer at a top tech company told me he felt that his current colleagues were higher-caliber than his colleagues at Amazon, and that many candidates that were rejected would have been accepted by Amazon. So that's a possible answer.

That being said, Amazon is still considered a top tech firm, even if it is a cut below Google/Facebook in prestige. There aren't many tech firms as well-known as Amazon. I can see many fresh grads going to Amazon for 1-2 years just to get it on their resume.

Maybe mathematics doesn't really predict the Universe. Maybe mathematics simply extends and reiterates within our mental models.

Where is the math that predicted Dark Matter and Dark Energy?
Well: a second person who was listed as a "victim" came forward to dispute she ever was victimised in any way, and that the account of her experience was severely manipulated. (It has since been taken down).

So that's at least 2 of the accusations that are somewhere between plain false and maliciously fabricated, with nothing on the veracity or lack thereof of the rest.

I don't know the guy, or what happened, but colour me suspicious, especially when you consider how the allegations were/are being made: not in any legal forum, but in a glossy PR website + campaign.

Doesn't pass the smell test.
I know very well how little of the flexibility exists for most developers around the world, but I explicitly asked how Amazon can be a good opportunity in Seattle. I'm curious what the benefits are, since there are so many negative reports from insiders. There are many companies you'd expect to read similar reports about and don't, so either there's a negative Amazon press union somewhere, maybe those working in warehouses, or Amazon's office workplace is really as bad as people say.
FWIW, I think the term was used often in e-sports to distinguish between it and 2k3/2k4.

Before the release of 2k3 there was no 99 attached to it and I know quite a few people including me who used the term "UT classic".

> These skeleton keys can be used to install non-Redmond operating systems on locked-down computers. In other words, on devices that do not allow you to disable Secure Boot even if you have administrator rights – such as ARM-based Windows RT tablets – it is now possible to sidestep this block and run, say, GNU/Linux or Android.

What's the point of disabling the ability to install another OS?

I can understand having a bit (that you can flip) in the BIOS that prevents accidentally or maliciously overwriting the boot sector of an OS. But what's the point of completely preventing it? What does it accomplish besides neutering the device and pissing off people that are trying to replace the OS?
Amazon recruits heavily along fresh CS grads, so there's always more flesh for the fire.

As an intern, I worked on a team that was rapidly spinning apart. We were resource constrained, one of the team members was in Ireland (and he always seemed to need help from somebody else on the team), and the manager... I don't even know.

The first day I was there, he told me to write a tech spec for a new version of one of the team's projects. The examples he showed me were all pithy high-level algorithm overviews for small features, which had 0 relevance to my project. I spent a week and a half groping in the dark for what he wanted.

About 4-5 weeks in to the internship, I asked him how he thought I was doing. He told me to think about the Amazon leadership principals and to tell him how I thought I was doing next week during the one on one. What kind of manager doesn't give feedback, even when the employee asks directly?

The business owner was a tall guy with slicked-back hair. I was supposed to meet with him in the first week. He blew off four meetings with me over the first month before I stopped trying to schedule them. When he finally deigned to meet with me (7 weeks in), it was to tell me he wanted a feature that not only didn't exist, but was so far away from what was possible that I didn't even know what to make of it. He would also do this shit where he would try to take other people's food, which seemed to me like an aggressive display of dominance.

My mentor, a senior engineer, was the only one who was really helpful. It was he who read my code reviews, he who told me that he was impressed with how quickly I had learned the framework, and he who was actually setting goals for me that made sense. He said he had my back for the hiring meeting, which put me at ease.

I didn't end up getting hired. I read and reread the feedback document I got, trying to make sense of what had happened. I hit all of my deliverable dates, I know my code was clear and concise, I went to the social events and talked to people from all over the org... What could I have done better?

The answer I've arrived at is I should have sucked up. I should have tried to identify the people with real power, and done my best to make them happy. The business owner was in the hiring meeting, and if I had gotten him on my side, I could have written 12 loc total and still gotten a job. Amazon had been pretending to the new hires and interns that there wasn't any office politics, but I've never worked anywhere more political.

A friend of mine from university got a job in a different org inside of Amazon, and he told me that he looked at my employee feedback on the internal website and said that it didn't say anything concrete about why I hadn't hired, just stuff like "obviously skilled, but not a good fit." Maybe that's the truth. I've just started working for a company whose namesake was just nominated for CEO of the year, and I already feel more at home there than I ever did at Amazon.
Or they thought it would be better than their previous place and were stuck once there. Or it was the only place to give them an offer. Or the money was too good to pass up despite the abuse. Or they accepted the abuse for the name brand on their resume.

Exactly, most science fiction representations fail on the engineering test. That' snot to say that some future change in our understanding of physics might not change what is in fact possible. One reason I love scifi is that the authors/readers/watchers are free to drop the need to be fully grounded and go for something truly cool. I suspect what we view as totally impossible today, might be within the realm of possible 2-3k years from now.

There are more important principles. Needs of the many; for example.
Nobody is forced to buy from Amazon. Why must the government be involved? These are consenting adults making choices. This isn't a cotton plantation in 1845. Employees don't like it: quit. If it hurts the bottom line, the company will adapt. If you think it should be different, start your own company.
Oh! shit, I misunderstood your proposal completely. That is definitely not the goal of Algebraic Topology... Sorry about that.

If you say two knots are equivalent, in mathematics, that means they are equal, one and the same. You can't have a tool that assigns different structures to the same thing. But I see where you are coming from. In mathematics we have the concept of a presentation (of a group or a vector space, for example). You can imagine a presentation of a knot like in a two dimensional representation (typical one) and assign an invariant to that. That wouldn't be an invariant of a knot, that would be an invariant of a knot, as you mention, but it would be an invariant of a knot plus some extra structure. Those objects are also studied in many instances in which the original is two difficult. As simple example imagine a knot plus an orientation. Invariants of that structure might be dinvariants of the knot.

While I think smart contracts are somewhat modeled after Western courts, the beauty of them is that they are predictable and deterministic. Doing various sorts of forks is quite messy, so perhaps the ideal smart contract system would have another layer between VM and forking.

In theory, if your OS isn't evil or easily hacked, it should prevent a class of "evil maid attacks" from attackers who don't have the master key (while facilitating irreparable attacks from those who do).

In practise, MS OSes are evil, easily hacked, and now everyone has the master key.

The security reasoning is that the device must boot intended operating system, and not just any system that conveniently lies around on drive. This is to prevent attack of switching operating system with look-a-like and stealing sensitive information from unsuspecting user. Also to prevent attacker from booting into another OS and reading disk content.

I wasnt suggesting they offer those services for free. If they were to consider this, I imagine buying an existing bank would be the first thing they would look at.

I'm happy to see Flash on its way out – I haven't even tried to install it the last few years. Native browser support tends to work and integrate much better on Linux than having to depend on a third party to deliver up-to-date software. The only site I visit that still seems to require Flash is the BBC, for video fragments.

There's some irony with Google blaming Flash for being spammy; I recently inspected what's probably the biggest shopping website in the EU because it slowed my computer to a crawl and noticed at least 30 to 40 outgoing connections, a lot of them to Google and its diverse ad, tracker and analytics properties.

The median tenure is 1 year at Amazon. Lots of people cycle through there. Though plenty of people stay for a while. They pay alright and it's not too difficult to get hired.

Also, when I was working there I had a difficult time reconciling myself to how bad it was to work there. On paper it doesn't seem so bad. You get to work on pretty interesting stuff sometimes, you make good money, typically you only have to work 40 hour work weeks, etc. I convinced myself to walk away from a good chunk of money just in bonuses to get out of there, some people might be able to stick it out longer or find the money harder to leave behind.

The problem is that having such a huge portion of the economy being involved in knowledge work is a relatively new thing, and we don't understand the differences between knowledge work and physical work. And especially we don't have thoroughly established standards on what constitute good and bad conditions for knowledge work. We tend to think that sitting in a chair for 8 hours a day is "easy", but it very much is not. A stressful working environment for a knowledge worker is just as bad if not worse than a physical stressful job working extended hours. I only spent a year at Amazon, and most of the time I probably didn't even put in full 40 hour weeks, but I hated it there. In comparison I view the time I spent years ago doing data entry at sometimes up to 70 or 80 hours a week during peak times as comparatively inconsequential. Depending on the team you're on and so forth, working at Amazon can be a painful and stressful experience.

Take being on call for example. In theory this isn't so bad, it's good to give devs exposure to how the ops side of things works, and it's in theory good to give them ownership of their own mistakes so that they have incentive to write good code. The problem is, you're not in charge. You're never going to get permission to dump the resources into making everything run well, ever. Most teams have other priorities and they don't have enough resources to spare to allow you to properly fix the code you're responsible for. Worse, it's not even your code, it's code that was written by someone else years ago who also left years ago. And the next person is just going to get whatever mess you leave behind when you leave. So in the average case you can't actually work to improve things, so being on call is going to always be an extra pain, and a significant intrusion into your theoretically off-work life. Worse, it'll push you behind on all the other stuff you need to deliver.

Meanwhile, you have all the typical office BS of politics, ranking, bad corporate culture, reorgs, etc. that you have to deal with day to day. Some people manage to find good teams in that mess, and others manage to just turn off whatever makes people care about work and just suffer through it for the paycheck. But for a lot of people, more so the more you care, it'll be a stressful nightmare. And the easiest way to avoid dealing with all those problems is to just leave, which lots of people do.

everyone's quitting... but Amazon's hiring does not seem to be picking up slack (unless they just increase the workload on current employees).

I mean, if a lot of people were quitting, recruiters would be trying their best to replace them. While I have seen a lot of open positions on amazon.jobs, they have been open for months (some even for a year) and are still accepting resumes (they seem to be taking their time replacing people if at all).

and in all honesty, I'd still want to work there if I can get a chance (so if Amazon employees / recruiters are hiring in Canada, please email me).

An example of salary from one wholly-owned Amazon subsidiary:
Base salary 78k.
First Year signing bonus: 30k, 10 RSUs vest after first year
Second Year signing bonus 25k, 30 RSUs vest after second year
Third year & Fourth year, 40 RSUs vest after every 6 months of employment

This was directly from an entry level offer and it is general practice to get a salary increase at annual reviews and more RSUs for after your fourth.

Like many RSUs, if you leave before your RSUs vest, you forfeit them. This is pretty much your 4 year incentive to stay.

EDIT: Clarifying RSU forfeiture
