For a little while now, I've been wondering why nobody has created email-like systems for social networks.

By email-like, I mean that it's decentralized... Everyone can run their own server. No 1 company has complete control over it. (Except possibly the root DNS servers.)

People can subscribe to content from others (like Twitter) and receive those updates automatically.

I'm thinking that when you subscribe to someone, their server is notified that you subscribed, and your server remembers it as well.

If the person unsubscribes, the other server is notified, etc etc.

When you post, your server tells every subscriber's server that you posted and gives them the message. If the person has unsubscribed, but there was no notification, an 'unsubscribe' response is returned, instead of accepting the message.

As far as I've thought it through, this means nobody can send you spam unless you are subscribed to them. No companies can monetize you, unless you use their server instead of running your own. With a set of standardized protocols, it should be possible to create twitter-like clients that hook to any server running this...

It doesn't have to be limited to 140 characters. It can have all kinds of extras, like media or hashtags built-in. Replies can be threaded, instead of hoping the other person knows why you are replying.

There's some other things to think about, such as what happens when a server is offline for a while. Does it poll everyone to try to catch up? Do servers send messages in batches back and forth, instead of dealing with things on a user-by-user basis? etc etc.
Well done and usable!

For the field of programming language design ask yourself this question: what will programming be like in 50 years? Will we still be typing characters into VIM? I don't think so. Looking a little forward can go a long way.
Yes, but it's sad that they didn't even try to charge...
I think the problem was they couldn't find enough people who wanted to use it for free, to bother trying to charge some of them with a premium package.
Well, just use runtime exceptions for your own code. (Though, they'll hardly ever change the exceptions in the base libraries to runtime exceptions)
This is promising news. I wonder, though, what is the energy cost of extracting Deuterium and Tritium, which for sure is not null, and if in the balance they are already counting that and the conversion efficiency of the heat generated by the reaction.

Based on what have been said you could try to establish your name as a unique brand: such as the "CharlesSchwab" for web design or like Donald Trump uses his name for his products.
I'm a big fan of Lua and Go's use of multiple return values, nil, and simplified error handling, (No exception 'types'). I think the problem with 'typing' Exceptions is that it means you are using it to record and pass describable\known state similar to return, instead of being reserved for unknown state. For indicating predictable failure states without using exceptions, I think multiple return values as used in Go and Lua is a much better paradigm. To recap Steve's post, opening a non-existent file in Lua:

=io.open 'sdfasdf'
nil	sdfasdf: No such file or directory	2

The first value returned is nil, the 2nd value is a string containing an error message, and the 3rd is an integer error code. This allows you to write most code using 2 state boolean logic:

f=io.open 'sasdasdfsf'
if f then -- nil is a boolean 0

whereas in Python, one often has to reason about 3 states due to the use of try\except blocks. Even though you are not using typed Exceptions, multiple return values does not discard any state about the error if it is desired:

f, err = io.open 'sasdasd'
print(err)

In Lua (not Go), when you combine multiple return values with an assert() function of the form assert(boolean, error_message), you effectively get a mechanism for making exceptions optional:

> =assert(io.open 'sdfasdf')
stdin:1: sdfasdf: No such file or directory
stack traceback:
[C]: in function 'assert'
stdin:1: in main chunk
[C]: ?

Although Go does not appear to include assertions at all, arguing against them in its FAQ: http://golang.org/doc/go_faq.html#assertions
The U.S. economy is stalled because of a wave of government legislative activism (health care, finance, bailouts, energy, labor) unseen here since the New Deal.
I would have been envious of Groupon if they sold to Google for $6 billion. Now? Not so much.
If fusion ever becomes feasible they should drop the word "nuclear". Given the current level of fear around nuclear power the possibility of people exploiting the naming similarity is worrying.
Certainly the "new" part of the title is full of irony, emphasizing the desire of people to get something else than the bloated, crawling, min_width=1024px, url-raping atrocity that is the new_twitter.

Which jerks?

The jerks stealing creations from creators? i.e. you consider

-or-

The jerks stealing creations from the public? i.e. you consider the

to be theft from the public.

Though often an unpopular opinion, these days, both sides are jerks. The

Cell network providers have only recently been dealing with this problem. Landline and Cable providers have been reselling the same pipe through "voice", "data" and "tv" channels for a lot longer, and they continue to get away with it.

Carriers will not voluntarily give up this incremental revenue. I live in Boston, when my choice of cable carrier are Comcast and errr... ummm.. Comcast.

Until there are more competing vendors, I think this transition away from arbitrary labels to one single dumb pipe will be much slower that we all hope.

It seems likely that the energy angle of NIF is mostly PR for a nuclear weapons research program.

But it is hardly serious to dismiss a research project because of test costs and that tests can only be run once a month. For instance, the Polywell WB-8 isn't exactly outputting more energy than is needed to run it, either.

High energy laser costs seems to be going down fast; maybe they really can make that pig fly...

I've used Notifo to be notified about HN replies and I'd say it was very useful. GitHub integration was useful, but I've actually used it only once or twice.

The important thing is not whether Apple should or shouldn't have won, but that they did. A court of law, as biased as it may be, has concluded that Apple’s complaint has merit. And now that may serve as precedent for Apple to use in other jurisdictions. Samsung are getting deeper into the crapper.

Paper Frames Debate on Big Brother in Critical Infrastructure
QUALITY OF SERVICE PROVIDER
This is why I only use the most basic features of vim. There are simply too many commands to learn and many of these tutorial and cheatsheets present you with too much information. I don't think the time investment makes sense, and I don't understand why there has to be so much noise: how many of those commands save a significant amount of time; how often are they used?

The questions I would like to ask advanced vim users, are:

(1) Imagine that you had your memory of vim wiped, and you lost the ability to remember more than 10 commands. If you decided to learn vim again which 10 commands would you keep in memory?

(2) How many commands does somebody need to know before they can used vim productively? Is it less or greater than 10?
That's what they kept saying 25 years ago, yet look where we are...

What User-Agent string are you using? It's a clever hack, but I can't allow my users to access sensitive information via your proxy.

The service was not intended for any copyrighted content, just as an easy way to pass files from one person to another that are too large for an email.

So, the 'jerks' would be those uploading any kind of copyrighted content, but especially those that figured this was an easy way to create a child porn file exchange. Apparently I'm too naive to think ahead.
Not really, no. As far as I can tell, they all provide products or services in some for to end users outside Amazon.com's retail business.

Ask HN: Scared of freemium test being all free and no 'mium'...
One of my many unfinished projects has now languished for so long that it's actually in danger of being finished sometime soon. I don't want to give away the specifics yet, but it's an ajax tool that allows you to tinker with some controls, and each time you do that it generates a dynamic output image of approx 100k. It's something you might use anywhere from just as a last-resort lookup, to an essential tool for a job/hobby that takes up every second of your spare time. At 100k per click, that'll add up lightning fast, and if it hits the right audience I can see it getting swamped. There's a few national magazines on the subject that sing the praises of much less impressive tools - one mention there and it could be adios! :/

Consequently, I wouldn't know where to start in estimating bandwidth use, and that's really all the cost I'll have until I'm ready to market it. The cost-free limit on my current host is 15G/month, but I haven't got the time/resources to set up anything better just yet. I have no money to throw at this, at all, no matter what. I'm in a situation where it costs me nothing or I put it off for a year :(

So, I'm planning to do this as a freemium with a fairly hefty restriction on the free and usage-bracketed costs on the premium so as to be fair, but I'm still scared the numbers might not add up and that the freemium could potentially cost me an arm and a leg before I even notice.

Does anyone have any nuggets of advice that might help? Even if it's just "It's a risk, get over it" :) I'd rather not abandon the freemium idea (pictures of it in action are OK, but using it is a hundred times better), but maybe the slower, safer approach of only using bandwidth that's already paid for is warranted for a skint coward?
Optional checked exceptions have some benefits.

Java got them the wrong way around - unchecked should have been the default, with checked available when you need them.

Because Java does them the other way around, you either get code bloat from the large numbers of exceptions you are catching and handling subtly differently or you have a generic catch(Exception e){..} block. Neither are ideal.

You are 100% right, but Apple has seen the last of my purchases. Not that they could care one bit but this kind of lawsuit is utterly ridiculous in my opinion, which may not be as powerful as the German courts but it counts for something.

Apple has won this battle, here's to hoping they will lose the war.

Imagine if every car manufacturer would have to come up with a new user interface for the basics of the vehicle, if having front, rear and side windows would somehow be considered something that you could have the rights to.

Hah, I've never actually looked at the Twitter app for OS X. I'll check it out.
I wouldn't use click-through rate to your pricing page as an indicator of anything. It's just too weak and remote.

Try getting people to type in their credit card numbers and click purchase. That is better, if you're going to use the "utilize landing page to measure demand" tactic anyhow.
A friend's site, where users upload lots of pictures every hour, gets millions of hits everyday. It costs him $20-$30 on S3 per month.

You're probably overthinking this. Just run the test. Chances are no one will care about your app.

But if you get lucky and get a bazillion hits, you'll find out very quickly. Stick some Google ads on. If you capture emails, you should also be able to convert some to premium.
I like it too. However, it is a little slow at times and I do get the "there was a problem sending this tweet" message a little too often.

It is the same thing. I created a similar tool for use on s60 (symbian) on several carriers in africa. Sitonmobile "packages" up the interactions with a web server into a series of compressed images and delivers it via mms where it can be replayed.
