Oops, I misspoke. Both Galileo and Beidou are GNSS, but both are incomplete, and are expected to be fully populated sometime 2020+. China has had a regional system up for sometime (Beidou-1), but I didn't know they've been planning and launching a second, global system (Beidou-2).
The cables themselves fail surprisingly often (anchors, fauna, earthquakes, material faults...) but most connections have redundant paths (almost every undersea network is bidirectional ring) and can be readily repaired (which is the thing that still surprises me)

Ask HN: How to solve US immigration for a foreign cofounder?
I have several offers to join a US-based startup as a cofounder/CTO. Hence, I'm trying to figure out a way how I can stay in US to work on my startup.

I did some research and talked to the lawyers, and their seems to be no straightforward way to do this.

To summarise, options are:

- find a job, wait for H1B until Oct next year and then work on my startup part time

- apply for a degree and study for 1-2 years, then have a year to look for a job without restrictions. Work part-time on the statup in the meantime

- O-1, I'm not sure if I'm eligible myself, but I know some entrepreneurs who pulled it.

I don't see a direct way to solve the immigration issue though. I think this should be a quite common case, so I'm curious how other hackers solved it. I'd really appreciate any legal hacks available, as the situation seems rather hopeless at this point.
I haven't actually been able to get through it for free yet.

As to points 1 and 3 I thought the article pointed out that the goal wasn't necessarily to make money on the $20mm invested in Snapchat, but to set the valuation bar higher for all their other VC deals.

This article is a little sensationalist.

Java is a programming language used for an awful lot of things, everything from high performance Stock Exchanges, down to tiny embedded programs. Docker is a container abstraction layer --- there is no comparison to be made.

The notion that Java was the "run anywhere language" and therefore Docker has removed that requirement is also silly. An ARM executable will not run on a Docker which is on an x86 Host. But... a Java program will. Docker is about making the environment portable... but the program still has to be explicitly written to run in said environment -- while a Java program still does not have that requirement.

Does anyone knows the total capacity of all these submarine cables?
The road from theoretical physics to engineering is a very long one, so it's very hard to predict exactly what this would buy us. Relativity, for instance, spent a long time with no concrete engineering benefit, but now it allows GPS to be much more accurate by adjusting for the time dilation on GPS satellite clocks. As we get closer and closer to the mysteries at the heart of the universe, I think it's safe to say that the engineering benefit will be both more arcane and more powerful.
New VC model: ignore about that valuation number. Just get X preference (like 4x+).

Then higher valuation works even better for you. Oh Facebook you really need to pay at least 6 billions, b/c we valued them at 10. Such a great deal. VC enjoy your 300% ROI.
Now I know the third movie in the Sharknado series, Sharknado vs Firenado.

That is an interesting link. Reading about the Australian fires an interesting question comes to mind which is this, "If we engaged these fires at the outset with a constant suppression/extinguishing scheme, would they still get to the size and ferocity that they do today?" that is something I don't know. CalFire jumps on fires pretty quickly to keep them under control, especially near structures, and those fires then evolve slowly. Unlike say the Yellowstone fire a decade or so ago which was left to burn 'naturally' and it got quite large.

Long ago, I was a stockboy at a couple of Woolcos, which were suburban, one-story Woolworths, both of them just opening. Once the store was open for business, every morning the sound system would kick out a jingle that I still remember most of: "With bargains excitingly wonderful/All the things you've been looking for/???/At your Woolco department store!"

We were not expected to sing along with it, though.
I find this binary opinion flawed.

Programmers have short term and long term views. If you push a release out with a huge painful bug you will QUICKLY rush a fix out even if you go into technical debt to do so. Alternatively (good) programmers do have long term goals in maintainable and stable code bases to deliver consistent quality software to end users.

Likewise a business-type has short term goals -- quarterly earnings, quarterly service signups, business performance metrics, etc to investors/wall street. But alternatively must have long terms goals too to keep the business alive and growing. Investors do care immensely about quarterly results but they also care about long term results. No one will invest in a company that is likely to go bankrupt after the next quarter. IMO business folks get lambasted a little too much on their "short term" focus. Point me to a company that had a strong quarter than is likely to go bankrupt within a year or two (no hindsight comparisons). Business types are constantly balancing short vs long term goals and companies are constantly figuring out better incentive structures to reward business-types for that balance. Is it perfect? No. Are there exceptions? Yes. But it's what is happening every day in the business world.
I think you may have missed the point of the article. The whole thing about not really caring about this $20 million but using it to "signal" the wider market (and thus generate higher valuations on their other investments going IPO or being acquired) was the whole point.
am I the only one who is confused by the way ownership works here? The article itself is more of a dreamy PR piece. However, looking at the website and the FAQ itself - I cannot really figure out how "app coins" work. Who creates them? I understand that they are distributed by bounties, but how many app coins exist? Who creates / mints them? How does the originator of the idea get his share? Would be great to understand this!

No, you just shouldn't accept paypal. As k3oni states, it doesn't matter how much money you have in your paypal account.

Well, the obvious if somewhat facetious answer here is "the URL to log in." Another, less facetious one is "a password reset link." But even if we accept that expecting customers to follow long lists of directions without error is remotely reasonable, it doesn't matter because scammers are certainly not going to be fastidious about avoiding links, so by avoiding them yourself, you are only making it more convenient for your customers to get scammed than to actually do business with you.

I can see the value in not blindly visiting URLs received via email. I do not see the value in refusing to send links via email. Unless you yourself are a scammer, making people do error-prone extra work to access your site does not protect anyone from getting scammed.

Of course, free support. I run into this all the time at work. Yeah, I am being paid, but it happens more often than you think that someone comes asking for something and they think you can just wave a magic wand and it's done.

Never mind they know it would have taken hours for them to do so without your help. This happens less and less when you can educate people about how much work it is to do a thing, exactly what goes into it, and what small things can be done to save you (them) from wasting lots of time on unnecessary work that may not be obviously unnecessary to them.

How much do you like your sister? Do you think she can afford to pay for ongoing support? Is it a successful business, or more fledgling? Is what she needs now so big, in comparison to what you've already done for free, that you feel you have to charge for it where you didn't before?

If you built it sanely, hopefully there is a way you can show how to do what needs to be done now. Normal people are usually afraid of making websites, and it's not that hard. You can do your part by making good backups of what you've already done and being available in case something goes wrong and it gets too hairy for a novice to fix. It should not be necessary for you to be responsible for editing copy on an ongoing basis.

Profits are paid out to partners monthly based upon their ownership.

Sharing ownership with other partners recognizes exisiting help and incentivizes future work.

I also sympathize, but when you start employing people, a risk you take is that they're horrible at the job. A way of mitigating that risk is by being careful who you hire and monitoring their progress. If you're hiring a programmer, make sure somebody you trust knows something about programming and is available to you.

I'm into firing quickly, too. It's a kindness.

The C10k problem is 15-20 years old. Tcl uses select() which can handle a maximum of 1024 FDs. In other words, it would not be able to handle more than 1024 connections in parallel.

Moreover, Linux and FreeBSD have introduced syscalls comparable to select(): epoll (in 2002) and kqueue (in 2000). Those are way faster than select() and I think there's (virtually) no limit on FDs. Tcl must be using select() for its portability I guess.

So, handling a lot of concurrent connections is an old problem. In 2006, the C10k problem was way behind. Even at that time, I would have expected a program to be able to handle thousands of TPS.
This post sets up and knocks down a strawman quite expertly. You're right, it's not just Anita Sarkeesian who gets death threats, threats of rape, etc. leveled at her by idiot troll gamers. That's gaming's culture of harassment and embarrassing childishness due to anonymity.

What the author conveniently ignores is that while Jack Thompson woke the gamer troll machine by being a living caricature of game-hatred, Anita Sarkeesian invites the same wrath by creating level-headed, well-researched videos whose only "incendiary" call to action is for the creators of games to be more thoughtful and inclusive in their use of female characters in video games.

The misogyny isn't in the harassment itself, it's in why the harassment is occurring.

> Bank bailouts had positive returns.

Compared to what? You can't compare it to the results of not having done bailouts, so the comparison is largely a matter of economic prediction, and economic prediction is obviously very controversial. The only non-controversial part is that the bailouts were certainly very good for the banks receiving them.
Unless I'm misunderstanding, they're really saying they're now insured for ~3% of the BTC they hold. For security, they've always said they only store about that much online, the rest is offline cold storage, but this post says:

"Coinbase is now insured against theft and hacking in an amount that exceeds the average value of bitcoin it holds in online storage at any given time."

So you're still at the mercy of their offline storage security. Not saying there is a better option for most people, but this wouldn't protect you against a Gox-like breach.

This article seems to forget the 'horrible' Facebook IPO where the stock went nowhere. Or that companies like Box who were going to IPO and then pulled back (presumably from a lack of enthusiasm on the road show). Or Groupon, or Zynga. There are lots of wounds not fully healed out there keeping the IPO market fairly rational.

That said, the article says Snapchat has raised $160M. If you push them to take money at a high valuation, you can cut them off at the knees when they run out of money. No IPO required, just sell off the company to one of the existing players for your liquidation preference and maybe a small premium.

I will be quite surprised if Snapchat tries to IPO before any revenue, but if they do make that leap I'll be really interested in watching the market response. That would be a good data point for bubble/notbubble arguments.
I suspect a better measure of valuation would incorporate the investment amount. If a VC firm invests $X at a valuation of $Y, then it conveys a lot of information (on the beliefs of the VC firm) if X is close to Y, but decreasing information as X decreases.
