but then the main vehicle would need to have duplicates added back on to position and de-orbit, increasing the overall weight
Except it actually did. The Space Shuttle's main engines were not used for on-orbit maneuvering, and were basically deadweight once the external fuel tank was jettisoned. Instead, they had separate orbital maneuvering engines that used hypergolic propellant for all of that stuff.
Every single time they fly a rocket to ISS they are testing their ICBMs, all Russian ICBM rockets are R-7 rocket based. Exactly the same rocket base used in Soyuz space craft. If they can dock on ISS,they can deliver a nuke on your roof, probably with even better accuracy.
Um, the R-7 design really isn't that practical as an ICBM. It uses LOX, which means it has to be fueled up right before launch. Sure, it may have originally been designed as one, but everyone quickly realized that hypergolic storable propellants were far better suited to that job.
At some point they will just call 'Gaza' the launch site and smeg it hard. And nobody sane will blame them.
Considering that their surgical strikes seem to receive the same international condemnation as carpet-bombing would, I really do wonder what would happen if they did that. (However, I don't actually expect them to do that.)
This is why I was never interested in working for any of those big companies that setup shop out in the middle of nowhere. Makes it impossible to have a life that isn't entirely dependent on a single employer.
Its also why it was a very easy sell for me to be convinced to leave a "normal" job several years ago and move across the country to work at a startup in Silicon Valley. Just having the opportunity to "insert" myself into the SV job market was worth it alone. (Before I moved, I was basically invisible to recruiters and had only a handful of potential employers. After moving, I suddenly showed up on their radar and was being contacted non-stop.)
Everyone praising BlackBerry's security was only speaking truths about BES. Everyone mocking BlackBerry's security was only speaking truths about BIS.
This was extra amusing and/or annoying when people only using BIS would talk about how they had all this security on the platform (that really only existed with BES).
Girls can definitely do math. However, it seems like its more socially acceptable for them to brag about how they're bad at it. Maybe that's the real problem here.
So I take it that you've never used any software developed under government contract, designed to meet a formally agreed-upon requirements document, that actually has a user interface.:-)
The alternative is giving this contract to one of your more traditional defense contractors, who is probably going to charge a lot more and deliver a significantly worse product. Oh, it'll also be late and grossly over budget, if it happens at all. And when all is said and done, they might procure Microsoft hardware anyways... as some component of their system that the news doesn't report on.
Every few weeks it seems like some reporter somewhere was assigned the task of ditching some specific ubiquitous tech thing for a week or two, and then writing an inspirational article about their experience. After which they probably resume using it and go about their normal lives.
Unfortunately most communication done on a phone pretty much requires the data plan. Okay, with the exception of non-VOIP voice (which many don't like doing anymore) and SMS (which only Americans w/o foreign friends/relatives think is good... everyone else in the world uses some sort of data-based messaging solution).
That's why Israel's own rockets launch to the west. However, those mostly get used to launch spy satellites. They also have a smaller payload capacity. https://en.wikipedia.org/wiki/Shavit
Correctly reversing an UTF-8 string with combining diacritical marks and embedded RTL substrings and other features could be quite fun, though.
Indeed, and also a great example of why you should use String.Reverse() instead of trying to handle it yourself.
What's actually more important to me is knowing that you have to deal with all those Unicode bits when doing the reverse... because someday you'll run into a situation where String.Reverse() (or equivalent) doesn't actually handle them correctly. However, actually implementing this robustly is far too difficult and time consuming to fit within the confines of an interview question.
From a hobbyist point of view, a while back I decided to actually tabulate the country-of-origin listed on Digi-Key for all the components I was using in a project of mine. While China was definitely at the top of the list, the complete list was actually a lot more distributed than I had expected.
From that exercise, here's the list: (this is counting unique part numbers, not the actual number of components for each part number) China (11) Israel (7) Taiwan (5) Japan (4) Malaysia (2) United States (2) United Kingdom (1) Czech Republic (1) South Korea (1) Philippines (1) Vietnam (1) Mexico (1) Thailand (1)
In 1991, [...] Restaurants all had smoking sections.
Back then, it felt like restaurants had non-smoking sections which were a dinky little area off in the corner. Then, a few years later, the sections swapped and it was the dinky smoking section. Then they finally did away with all of that.
When I was a kid, avoiding cigarette smoke was seen as a deliberate decision and request (which my parents frequently made). Thankfully, now, smoking is pretty much out-of-sight/out-of-mind. I only even know it still happens because I can smell it on the breath of people who I've never actually seen smoking in front of me.
Actually, the different content/data formats of the various apps is going to be a far greater problem. Because of end-to-end encryption, far more of this issue gets pushed down to the client, and cannot be handled seamlessly on the server.
Does anyone know of a Whatsapp alternative that doesn't suck? End to end encryption that is promised by someone that's not scummy like Facebook or Google? What Whatsapp used to be before being purchased by Facebook. Needs to work on apple and android.
Telegram. Now it has nicer features than WhatsApp or Messages.
The source is open - better scrutiny. macOS, iOS, Android, Windows, Linux. Conversations move seamlessly from one device to the next.
Telegram pissed off both Roskomnadzor and NSA because it has strong encryption and little central oversight - a bonus. If it's good enough to piss Putin's goons and our goons, it's good enough for us to use. I work nowadays with a couple of major VCs, and most chat about deals and other sensitive topics have moved to Telegram because it makes everyone feel less exposed than with Google/WhatsApp/Slack/etc.
Cheers!
Telegram does not do E2E by default. Please stop deluding yourselves into thinking its somehow a "more secure" option. IMHO, any messaging product that not do E2E-by-default is just implementing E2E for the purpose of paying lip service to the idea.
Did XMPP/Omemo ever bother to implement a retry mechanism for E2E messages? The last time I looked, it seemed as though they decided to not implement one.
A robust retry mechanism is what makes *the* difference between a toy for tinkerers and a robust project that's actually usable in the real world. And yes, I speak from experience when I say this.
I keep feeling like I should do this. Those people seem to have absolutely nothing better to do with their lives than sit on the couch and share outrage-promoting drivel all day long. Slacktavism at its finest, and they think they're actually accomplishing something useful by engaging in it.
Then again, if you remove those people and everyone else who only does it for 20% of their posts, suddenly the whole feed would feel quite empty.
Mostly in the case that you actually want local storage of media, because "the cloud" isn't necessarily a performant and always available option for everything in every use case.
Yeah, I wonder that too. Anyone who buys a set like this has likely invested real money in a sound system that's separate from the TV itself. There's really no reason they'd even care about having any speakers in the TV at all. (unless it can replace/complement the existing center channel of an existing sound system)

Just look for the "neckbeard" or "incel" comments as proof. What is the female version of those two terms?
Crazy cat lady?
(Then again, its almost orthogonal to most of what's being discussed here.)

What's their high-speed roadtrip-oriented charging solution?
I'm still waiting for anyone besides Tesla to seriously consider this issue as a critical part of the EV ecosystem.

I really wish they'd just make a 4k OLED panel at this size. Until this launches, the largest OLED panel on-the-market for years now has been 77in.
