You can certainly ignore both limits in your homemade-receivers, but if you ever want to ride faster than 1900km/h you will have to account for an increased doppler shift (I hope I'll not help any terrorists by explaining that ;-) ), and even though I (in the end) realized that this is not as dramatic as thought at first, just let me write down some calculations:

Doppler shift is the change of the percieved frequency when either source or receiver move towards another, or away from another. Canonical example: Sound of a emergency vehicle's horn when passing by.

Normally you never see the satellites ride directly towards you (or away from you) but the path is pretty orthogonal to your line-of-sight. So you only account for a fraction of the 14'000 km/h speed of the GPS satellites to cause frequency shifts of the signal. (Max. example listed on the homepade-GPS page is ±5 KHz of doppler, which is relatively 3.3×10^−6 of the GPS frequency, even though the GPS satellite rides at 1.8×10^−5 the speed of light).

If you'd fly with 1900 km/s (1.8×10^−6 of the speed of light) directly towards the GPS bird, this movement will increase the frequency you receive by 1.8×10^−6 × 1,5 GHz = 2.7 kHz. So please increase your doppler search range from ±5 KHz to ±8 KHz to be able to successfully steer your homemade cruise missiles at that the COCOM limit speed, increase more if faster. This will slow down your time-to-first-fix, obviously.

The other limit of 10km is easier to ignore, though. It would only become relevant once you can no longer exclude some solutions to the formulae that lie outside of the GPS satellite's orbit (imagine four coplanar GPS birds used for calculation). And in practice proabably it's sane to assume a position that is not wider than 100km from the earth's surface, again, if you don't plan to ride your DIY receiver to the ISS, or maybe even geostationary orbit.
You seem to be claiming Kerala as the norm rather than an outlier. You're certainly welcome to compare crime rates between the two and/or suggest explanations/compare living conditions, but saying that very low crime rate is the norm is simply false [1]

Sounds great to me. Google needs more standardization in the Android ecosystem, not less. The fragmentation problems were bad enough as they were. This should fix the problem quite a bit, at least for developers.
Even though I very much prefer having an FB login, and think that is much more secure than having manual login (and thus having to remember passwords, which most people will "solve" by the having the same password, which is really insecure),for the love of god, keep your social logins down to 1-2 options, if you must have them. Please do not throw in Facebook, Twitter, GitHub, Google, LinkedIn, and the rest of the kitchen sink.
If you think just adding people will solve the problem, you've never called Virgin Mobile's support line.
Selling.. though point. I was never good at making up prices.

I use my real name. Have for a long time. The main reason is I'm too lazy to do otherwise. Privacy is hard work. And you only have to fuck up once for the whole thing to come tumbling down: forget to log out of one account and post something under the wrong name and your anonymity is toast.

The other part of it is that if you look at politicians who have gotten caught, it's always the cover up that kills their career rather than the original offence.

My preference for real names stems not from some idea that it makes us better people (I've been in real-name-only communities and there's absolutely vicious, horrible people who participate and are just fine with their vicious horrible nastiness being attached to their real name, because they consider that a small price to pay for being mean). And sometimes real names means there are negative consequences for me: I'm a Wikipedia admin and because I use my real name as my username, there are certain tasks I just don't go anywhere near because I've seen the doxxing and other shit that's gone on to other people. And mostly my fellow admins are fine: they understand why I don't want to deal with certain people—there's plenty of other people who can deal with the stuff that I'm not inclined to handle.

No, there's a much better reason for it. I've done secrecy in the past. Nearly a decade of it: it's called being gay and in the closet. And it really is a fucking waste of life. It makes you utterly miserable. Coming out is a huge psychological relief. Ten years of fear of other people's judgements is a long time to put off having relationships and, well, life in general. The misery of the closet made me make decisions about my academic/professional career that I have come to regret too. But to come out, you need to reach the stage where you don't really give a fuck what someone thinks about you. That comes with age and maturity and self-confidence.

The reason I'm open about my life is that I've tried the alternative and it didn't work out for me on a pretty epic scale. There's something very freeing about being very open about life and not giving a shit what people think.

When you've successfully left one closet, building new closets to hang out in starts to seem like a very bad idea. Sure, people might judge me negatively based on what I say. But they might judge me negatively simply based on who I am. I don't care enough about their opinion of me to not live openly and speak the truth as I see it.

I wrote a long-ish post about this kind of thing recently: http://tommorris.org/posts/8268
It's a nice surprise to see tpope as one of the top donators. What he has contributed to the vim community through his plugins was already worth much more than that IMHO.
He is definitely in the top 10.
Actually, I'm quite happy to see 'shitty grocery apps' outsourcing authentication, since it means they don't have a database full of plaintext passwords.
Did they consider that people tend to not use their facebook account for work accounts?

Anything relating to my job, I use my work email with a password. Anything personal, if I have the option, I use Facebook and don't let it to post to anyone but me.
yeah, sry. this.
Here's an extremely approachable chapter on quantum algorithms from an undergraduate algorithms course:

One unfortunate side effect of adding APIs to Google Play Services, is that it becomes almost impossible to test your app on Google's own SDK emulators. Play Services does not run in any emulator. You can try to find the Vending and related apks from CM or wherever, but Google doesn't help you do that .. and its a pain ;)

So if you want to use the new Play Services Maps API, you'll need a device.

I really wish they would find a workaround, because I use the x86 emulators to test various screen configurations.

Also, while this does provide a layer Google can update independently, it doesn't impact most of the OS. So security fixes, or fixes to the framework, sqlite, dvm, kernel drivers, still need to be handled differently.

While we're on the topic of Yahoo acquisitions in 1999, here's another: http://money.cnn.com/1999/04/01/deals/yahoo/
Play laser games with your cat from afar with Petcube
i was a part of the team that bought GeoCities at Yahoo, and i think it wasn't as dumb of a deal as it looks on paper, because a) YHOO stock was so high at the time that the $3.8B wasn't actually all that dilutive, and b) buying GeoCities ensured Yahoo was the #1 destination online, and thus we could command a disproportionate share of ad revenue. If you wanna look at a really silly deal that Yahoo did, how about the Broadcast.com deal? Billions for a bunch of servers...
Okay, this is good. The only problem is that I'm out of excuses to actually not use it.
Can anyone find the 27 actions? I find only one, add a school. the rest is just normal interwebs stuff. if you feel that every link is a must-click, even button a must-do, and every post a must-read (all contents), you have to rethink your web experience.

Personally I feel the images made me read the post instead of skip it altogether. I feel the white is indeed a bit much, luckily a lot of people add pictures to fill that up (pun intended). I dare to say that pictures are to a post, what icons are to your desktop. Try removing all icons from your desktop and just use textual shortcuts. That will make sure it is a pain to get in a glance what is there.

Lucky for people like the poster, google tends to make stuff configurable. As said before you can tune things (a bit) to your likings.
Oh, those heads days! That a "website" could be bought for $3bn+ prodded a lot of young employees to say "WTF, let me quite my job and make a website.com". I should know, because I was one of them.
How is this relevant?

Different era.
Different CEO.
Different corporate culture.
Different demography.
Different way people use the internet.
Vastly different size of users.

Tumblr could very well die on its own without anyone's help. Last I heard it was not making any profit yet, and took huge amount of money from investors. In the long term, investors don't care how many users you have if you are not making much money.

I personally want tech industry to get away from 2-3 companies dominating. I want a new challenger, that could be yahoo (we don't know yet), but I am willing to give them the benefit of doubt; and a chance to prove themselves under new leadership.
"Exclusion constraints would be pretty hard to implement in a distributed system."

It would be cool, though ;-)

"constraint exclusion wouldn't be all that rough, would it"

There are two interpretations of that:

* Passing a predicate down to the remote side so that the remote server can use it to exclude partitions. I believe this already works.

* Using CHECK constraints on the local side so that foreign tables can be excluded on the local side. This is a little trickier because it's hard to know that there are really no tuples on the remote side that violate the constraint. It's debatable how important that is, but it does need to be handled sanely somehow if the situation arises.
It should be noted that MailChimp is huge. I have no figures, but I'm guessing they have millions of users. This means that problems that affect 0.1% of their userbase still represent a nominally large number of users. They don't have problems like user acquisition and brand recognition.

For me, adding 'signup with Facebook' has increased the number of registrations. I'll worry about the effect on failed logins when it proves to be a problem.

android device manufacturers and telecom companies have no incentive for updating the OS, they would prefer to sell new devices with new releases, so chrome style versioning is the reason for the mess.

lets not compare iOS, Apple devices are pricier but they are fully supported for hardware and software for 3years, and most users do update their operating systems within days and weeks of a new release
Ask HN: I have a good idea and a POC... Now what?
So, I'm a young-ish(less than 25) programmer who enjoys creating things. New things. However, I find it hard to meet people I can discuss my ideas and projects with in detail. I have over a dozen half finished proof of concepts, but I rarely can get beyond that point. The big thing being that I just can't build any "anonymous" steam on any of my projects.

Most of my projects are open source, and this is where I get to hear crickets most of the time.. which is OK. I write code because I enjoy it, not because people like my projects.

Anyway, so now with a change of pace I have an (at least) initially proprietary project I've been working on. I have an ugly, but functional proof of concept. A semi-clear way to monetize it. And even a plan on how to initially promote it. However, I'm missing one huge piece in this whole equation: Feedback. I have absolutely no feedback right now, which is quite demotivating. I'm to the point that I could show someone my application and get feedback, but I can't just publicly show it because it's so ugly and incomplete. I need someone who can share in my vision and see the end goal and point me in the right direction to get there.

Technically, I think this is basically a cofounder. But, I'm not sure I'd want someone by the title of "cofounder". I'm fairly committed to this project in my freetime, but I'm not going to be quitting my day job or anything like that.

At one point I turned to WeekendHacker to try to get feedback, but that website seems gone beyond recovery with how little activity is seen there now. I don't want to do some freelance thing. I want someone who I can get feedback from

I'm young. I have no idea what I'm doing. I'm just creating something I genuinely wish already existed. Now what? I've proved it's feasible but don't know the next steps I should take. I need someone to bounce ideas off of and to generally guide me with the things that are beyond my skillset. What do I do?
That Aol, Yahoo, and Geocities were the top sites on the internet back then makes me wonder if we're now screwed out of the future innovation that might happen because our big 2, Google and Facebook, may be too big to fail (or at least fall), at least for a while.
There are a lot of conceptual differences, but I'll give a couple very important examples:

* With FDWs, you can push down predicates to the remote end. So, if you do: "SELECT * FROM myRemoteTable WHERE id = 2345", then it can just use the index on the remote side rather than pulling all the data to the local side and filtering.

* You can (as of 9.3) insert, update, and delete on the local side and it will pass through to the remote side.
" In a separate announcement, GeoCities posted a net loss of $8.4 million, or 27 cents a share, for the fourth quarter ended, compared with losses of $3 million, or 14 cents a share in the year-ago period. Revenue for the three month period rose 341 percent to $7.5 million. For the year, the company lost $19.8 million, or 71 cents per share, compared to a net loss of $8.9 million, or 44 cents a share, in 1997. "

and bought for $3.57 billion... With 19 million unique visitors per month, or 228 million per year, you'd need to generate revenue of $15 from each of those _visitors_ on average to just return the investment... (not accounting for the losses)

The good ol' economic sense of the 90's... That said, hindsight is always so 20:20.
Yes and No. I don't have my full name in my HN profile but if someone wants to find out he can google my handle to find out my real name pretty quick.

What's interesting is that this semi publicity holds me back from posting controversial opinions on HN. Feels like there's some commissar watching over my shoulder.

I don't really like that feeling and that's why I'm not a regular power poster on HN. I spend way more times on anonymous/synonymous forums.

Andrew, why is this your first comment or post?
I didn't get the same feeling as you. I received it with quite a bit of warmth, with a little bit of wistfulness? Try picturing Gandalf saying the words.

What did you do for volunteering? I'm sure each type has their pros and cons. For me, I once volunteered to help abused children. One of our activities was to help them create a board filled with drawing of people that they can trust. We went through it with all the kids afterwards, adding where they can find them. Helping, no, empowering those kids was the most fulfilling feeling I've felt, and this was almost 7 years ago (I'm 22).

Unfortunately, I haven't traveled (world trip coming after I can freelance), but I hope that it will reveal more about myself as a person as I put myself into new situations across the world.

Udacity has some permanently-on courses, where you go at your own pace. It's wonderful for the ability to binge study, but the lack of schedule might allow you to push it off indefinitely. For my own part that's still an open question, but I loved being able to binge during the easy part.
For the history books, Yahoo's M&A has been more trend-defining than anybody else.

Sure there are (some inherited from WebKit).

Though note that submitting and then completely ignoring the standards group (which has also happened) is not much better than not submitting at all. Especially if the submission doesn't actually give much more than the name of the API and a general idea of what it does.

I guess I don't understand what Page was trying to communicate? That there is still room in this world for people to make a living, as long as Google decides they aren't interested in that market?

Extract from circular:

[...] the German High Frequency Trading will require exchanges to determine appropriate order-to-trade ratios and a fee for excessive system usage. Moreover, rules for flagging orders that were generated through algorithmic trading are to be included in the exchange regulations. These requirements are not only relevant for high frequency traders, but for all participants who generate orders algorithmically (e.g. participants facilitating quote machines).
My opinions change regularly, I am sometimes enlightened, I sometimes have a change of heart. I don't post with my actual identity because of this.

I edit freely because of this. I don't care if other people hold old stuff against me; that's just people communicating with ghosts in their head. If someone has a serious problem with something I said, let them openly talk with me about it, or be counted among the people I just cannot be bothered to care about.

As I like to tell people: even human history is a HUGE thing compared to my own life, not to mention the universe. If I am lucky, I have 80 years to think and talk about all of it, and nobody, no boss, no relative, no friend, no life partner, could ever matter so much to me that I could completely swallow that thinking and talking, just because it might offend them. If in doubt, burn the bridges, think and talk freely, that's my motto...

I closed a lot of doors for myself with that, but I like the integrity I traded them for, I would not change a thing. Looking back so far, I would say anyone that ever mattered, didn't run away from the first misunderstanding, and not few friendships began with arguing over something with a stranger. On the other hand, the people who got upset about random superficial things, I don't really miss. So what could be better than having a website that filters some of them out, before we waste too much time and energy on each other?
Am I the only one who looks at the picture and sees an arrogant, deluded, asshole?
I'm not sure what you mean by the "dot com rush" but if there was a singular "dot com" starting-gun, it was the Netscape IPO a few years earlier.

Over time as more browsers implement these emerging standards, the foundation layer will diminish and ultimately disappear.

Don't get emotional about sunk costs - It happens because we are all human, but will not benefit you.

Take a small break - Focus on the present parameters, analyze all your options (other than giving up), give it a fresh look. One can make very bad decisions when emotionally compromised.

Be honest with your co-founders, and it seems that you haven't been speaking to them candidly.

Ask for a salary and set a deadline for them and for yourself. Beyond that just leave. I would not expect a market-linked salary at a startup , but I would definitely not like to work for free or with a salary that makes me struggle with my basic financial requirement.

Remember, you made an investment - in terms of time and effort - Calculate the financial value of the time you spent (like what you would have got in an average job otherwise).
Check if you are getting fair enough equity - for all your investment

You feel like "giving up", but if you have to do that, do it gracefully - give it very detailed attention, Work out all options in a comfortable timeline - and may be then if still doesnt look good - leave.

Believe me, "i gave up" will stay with you for your lifetime, if you din't try all the other options before that.
So is this production ready? Excited about this, but I don't have time at the moment to dabble on things I can't use and the last comment regarding this is a post on Quora from the founder saying that it is not production ready yet. 1.0+ version numbers makes you think this isn't beta software anymore, but that doesn't seem to be the case.
Agreed; this study seems to only find correlations between parenting and happiness/success in life.

What if some children grow up in certain ways regardless of how they're raised, and this is what causes them to have shitty relationships with their parents? Maybe some kids don't get good parenting simply because they became little shits? And then this carried on into their lives?
In my opinion the worst thing about WebForms were statefulness almost everywhere and very complicated page lifecycle including the refresh of nested components. For small applications it's great, but has problems when you're trying a large, dynamic product. Composability is much easier with MVC, where you can link to controller actions instead of always depending on the way nested controls process postback events and rebuild themselves.
