If you want to take it off the grid (versus letting it ring out in silent mode), you could put it into airplane mode.
cool. yet I find it hard to understand why is it so important to see a trend of a link. in other words, who can benefit from this information and how?
Looks like the 2012 Republican Nominee can look forward to some generous campaign contributions from Sony and Nintendo.
Pretty fantastic actually.
After ~6 months of using my call phone as my alarm clock, I now have a strong pavlovian conditioning to several of the Verizon ringtones, especially "rings"

I'll hear it randomly in public in the middle of the day and immediately get a rush of adrenalin -- "oh fuck I'm waking up 6 hours late aaaahhh!!!" -- and it will take me at least 15 minutes to calm down fully. For hours afterward my ears will parse any plausible input into phantom ringing (that happens randomly by itself too).
I noticed it sometimes comes out in bursts (which is terrible if you want to get on the most recently updated chart). No idea why.
I never said "too old to be out of the question". We've had presidents under 50 and I'm sure there are strippers over 40, too.
Maybe we still don't large enough concentration of any kind of ideas, let alone great ones. Cheerleading is useful, and you have the basic dos and donts in the article to stop it from becoming a bogus idea.
It's the _perception_ of ephemeral, through the UI and the way twitter presents "real-time" (most recent first, difficult to scroll through older stuff, less than stellar search (at least compared to other services)).
I have one of those alarm clocks that lights up the whole room over a 30 minute period - that makes it easier to get up in Winter. It also plays the radio gradually louder. I also have my iPhone alarm set on my desk "just in case..."
I can usually take some advice and work out if its useful. Sometimes just stopping and thinking about it makes it far clearer. Some people give great advice, and terrible advice at the same time.
There are many reasons to do things other than money, but when you are dealing with people that you don't personally or directly know the fact that they are willing to pay for your services is basically the only real signal you have as to whether you are benefiting them. And if you are not making more doing this (for a combination of monetary and non-monetary benefits) than you could something else, then you need to switch to a better use of your time.

Of course, the contributors benefit from donating money, etc by signalling effects and warm fuzzies, but that doesn't mean the recipients are benefiting nearly as much as the contributors are spending.
Not as a replacement, but I've used them a few times. But, after totally overdoing it on energy drinks (to the degree that I wasn't able to drink any for a few months without getting sick), I'd recommend taking it easy and keeping them for those emergency late nights, rather than making it a regular thing.
Not exactly.

Haram = Bad Deed (sin)

The opposite of that is Good Deed, but actually

Halal = neutral (permitted)

I don't know the Arabic word for Good Deed.

So:

Haram = -1
Halal = 0
??? = 1

PS. English does not seem to have a single word that means "Good Deed" (like how Sin means "Bad Deed"). But I bet arabic does. Would be interesting to know which languages have words for the various levels. (Like a word for "permitted but discouraged", and other variations.)
Except that they aren't US companies, while Apple and Microsoft certainly are. Most contries take a dim view of foreign corporations meddling in their politics, especially monetarily.

Java vs C performance, from Cliff Click of Azul
For a long time I thought I followed the same schedule. Since I'm in grad school, I decided to experiment with that. I found that I was not a night person after all. Rather, anxiety and thinking about a given problem kept me up indefinitely.

I even tried the experiment where you stay up until you are tired, then repeat. It was terrible. After a week I could not sleep at all. I'd get tired when the sun set, as we are supposed to. But despite being tired, no sleep came.

Through much pain, I discovered that the major source of my sleeplessness was a lack of social contact. Now this varies immensely by individual. But the moral of the story is that every sleep problem is unique. Your solution is not my solution. And mine is not yours (I don't have a good one btw).

I'll guess that sleep researchers already know this. Best of luck hacker news!

Just an interesting fact to share:

Ray Kroc of McDonald's fame was in his 50s when he started the business. The McDonald's fast-food chain happened to become successful company and top-brand within Ray's lifetime. He died in the 1980s. Before McDonald's he hadn't been known for anything truly glorious and exceptional as achievement.

Perhaps, besides amounting enourmous experience and insight about restaurants and sales. Something which took him decades in the hard way and is recognizable only afterwards.

http://en.wikipedia.org/wiki/Ray_Kroc
There's a single word for "permitted but discouraged" in arabic (makruh) but no single word for "good deed" AFAIK.
I'm not sure that's an inherently "design" focused activity. In order to become popular, you have to design something that people want to use, which is captured by several of the points in the article (e.g. "talk to people"). Once "design" is done and "marketing" begins, then there's a whole different article to be written (one that would be equally interesting, but which I largely lack the expertise to write).

I think rank is actually more interesting. It shows how much "visible" is an item, i.e. its potential/relative popularity along with its current one.
Alarm goes off at 7:22 (for some reason the snooze uses 8 min intervals - so if I'm tired I'll have 1 snooze until 7:30 otherwise I'm straight up). Pee, puke (morning sickness), shower, get dressed, breakfast.

I don't have any problems getting out of bed.
I become conscious sometime in the afternoon, take a quick look at my phone for any missed calls/e-mails/text messages etc, and if they need immediate attention, I pop open my macbook pro and go to work. If there are no critical issues, I usually jump in the shower and "meditate" for 30 minutes to an hour. Then I usually get to work or whatever I planned on doing that day.
There is so much good advice in this that it's hard to know where to start, but I'll pick this bit ...

Ask HN: Best Unix Tricks?
HN, what are your killer Unix tips? I've been using and learning about Unix both at university and at home for almost a year, and I was wondering -- what are the things that, when some wizard showed them to you, you wrote down as soon as you could so you wouldn't forget them? Is there some trick that saves you a buttload of time? Some script that makes your job way easier? Some command that made you smack your forehead in frustration when you found out it could be that simple?

Note: I'm personally looking for tips for working in bash (specifically OS X stuff if that makes any difference), but if there's some amazing thing that only works in zsh under Debian or something, feel free to suggest those too -- it's sure to be useful for someone.

I had a quick search for previous topics on this, but all I found was http://news.ycombinator.com/item?id=103725 which had a couple of badass things in the discussion.
Really? I never take naps. My wife will, but I just can't do it.
Probably only me - but to my mind that's a shame. It's only my opinion, but I think Flash is nuts for anything new except video at the moment. I think Flash is:

- slow

- fairly unstable, even on Windows

- a privacy nightmare (cookie system)

- being left behind by browser vendors, where there is competition

Excanvas on IE and the canvas tag are really well placed for visualisations like these. I built a donut chart in Canvas recently for something I'm working on, and I'm glad I did, because I was able to do an impromptu demo with someone just the other day on my phone.

I know it's not a critical piece of engineering, and it doesn't actually matter, but I do personally find Flash dulls my enthusiasm for otherwise very nice things!
Spot-on, I like to change my wake-up alarm tones frequently to prevent my brain from filtering them out + preventing the effect you describe here.

While writing up my PhD I went through three different sleep styles, each time for four months.

The first was to work nights. I'd get up at 15:30, "breakfast" at 17:00, socialise from 18:00 to 20:00, then go to work. I'd eat my last meal at 07:00 (bacon eaggs and toast are an interesting "last meal of the day") and go to bed at 09:00.

The second was to sleep every other night, sleeping for 12 hours when I sis sleep at all. The night I stayed up I'd catch a cat nap at about 03:00 for 20 minutes. This was effectively a 48 hour day.

The third and most interesting was to stick to a 28 hour day with 8 hours sleep. This gives a 6 day week, and I'd drift in and out of phase with normal people. That really suited me, and I wish I could do it more.
Isn't virtue the opposite of sin, in English?
Good points. I was imagining a scenario in which users/other-app-providers would be able to define their own Javascript functions, Google Caja http://code.google.com/p/google-caja/ style... in which case, the app should simply only need to whitelist adding trusted hosts/base urls to <script src="" />...

Also, see Drew's comment below where he was able to find an XSS exploit in FriendFeed due to them accepting '<' and '>' in the callback value... a reflection of how most security exploits come from combining different vulnerabilities.

Hope I make sense?
No, I am not kidding you. Compared to child mortality (USA: #33) the difference between 4MB broadband and 8MB broadband is trivial.
"The big thing coming up in October is the inclusion of CouchDB into the Ubuntu Linux distribution"

@ars, @tfh: That should be thawab (or sawab, not sure of spelling).
At 6 AM, after 8.5 hours of sleep and after a sunrise alarm clock has been getting brighter for about half an hour. Then I make breakfast and coffee and try to have an uninterrupted 2 hours of working on personal projects before going to work.
I think you should not read 'sin' to mean the same in the eyes of everybody.

For different religions there are different interpretations of the word sin.

The one common element they have is that they refer to a violation of the contract with the deity in charge, a transgression of the 'law' if you will.

So, if 'to sin' is transgressing a law then 'being in compliance' is the opposite of that.

Atheists are lucky, they are incapable of sin.

I don't know.

Would you say "I did my virtue for the day"? Like people say "I did my good deed for the day".

I looked in a dictionary, it has a lot of meanings, some of them do match, so I guess it's pretty close.
Tell me what's wrong with this thing I built recently :)
That's a good idea, but it's also battery conservation and the knowledge that it's also OFF. Certain processes can hang and chew through your battery until you restart, which is also why it's nice to turn it off of a night.

The "bad list" is manually generated.

Maybe they should hire 4chan to help edit the list - I'm sure they know every single possible bad thing you can do :)

I always wonder how the religious people who have to generate these block lists handle it. I wouldn't want that job, but it seems wrong somehow to hire someone for whom it's not a big deal.

Maybe someone who has seen these types of things before, but stopped.
On a different note, do you find it annoying when nytimes.com forces you to login to read an article?
Run a compile job, or a video encode... then try web browsing.

Perhaps you could time clicks to open new tabs in your browser. Or switch virtual spaces.

With the background work, you should notice no or very little difference. Since the interactive work should get highest priority(this is what you are aiming for).

You can try these tests without bfs patches too. You can see how the default kernel/X11/driver is not optimal - and how things can be improved.

It's still much nicer than OSX, and windows however.
The client has to have a public internet port available for XML-RPC or an HTTP post. The central cloud server sends pings to all of the subscribers.

It's a bad idea.

If you're going to do this, just use XMPP. Otherwise, use HTTP the way it was intended and just have the client poll the server. Why does everyone think this is such a bad idea? Polling works. It scales. It's simple.

svn update

Not a complex command to run! I hear there are these things called cronjobs too, so you don't even have to run it yourself. Just pick the latest stable branch and svn switch when a new major version comes out.

Economics is not a natural science
It's a great kill-ur unix tip but you should never fall for it:

:(){ :|:& };

Oh, the temptation... if you're thinking of cutting & pasting that into the shell of your machine google for 'bash fork bomb' first, I've left off the final ':' to set it off.

Anyway, on a more serious note, after an installation procedure that was a lot of work, if you want to document the whole thing use:

history | cut -d ' ' -f 5-

To give you all the commands you executed in the last little while, cut & paste that and you have a pretty good start for a how-to.

It's not a 'great killer unix tip', but it works for me.

Edit: Another one just came to mind, the ps command has a very useful option that is quite undervalued imo:

ps ax --forest
This is a charming little essay. But why?

- The "exoskeleton" metaphor for an N-list having its skeletal structure on the outside made me smile.

- I like the explanation of N-lists having a flat structure. Clean modules, with no dependencies. If your code can naturally fit this structure, it will be simpler. Alan Kay says that by inventing new representations, we make their users more intelligent (e.g. multiplication with Roman v.s. Arabic numerals). If your new representation enables its user to think in flat terms about what previously required nested or recursive structures, then you have done something great.

- These are playful and novel ways of looking at commonplace things. They evoke my conviction that gold is all around us; just a step or two off the path is something incredible. All you need do is look.

But underlying all this is the lack of any discernible ulterior motive: it's just for fun. :-)

And this great speech is not allowed to be shown to students in need due to fear of Obama's socialist ideology?

Yeah, most people treat capitalism more like religion than an economic system of choice, especially the disastrous one we have now.

A return to the less devastating Keynesian sort of capitalism won't undo the whole mess though.

Alternative digital economies of sharing have shown how there are plenty of other viable models of economic organization.

It's time to reevaluate the failed system that brought us here.
since their customers don't provide funding

That depends on your point of view. I'd argue that the people supplying the funding are the customers and that the work they do and people they help is the service they provide. So if their customers aren't happy with the quality of the service they'll take their money somewhere else, exactly like in the for profit case.
I've worked at two social ventures that had non-profits as clients (Web Networks, and most recently Urbantastic.com).

There emphatically is something wrong with non-profits. Just because there are some excellent ones (Sturgeon's law applies) doesn't mean that the field at large isn't ill.

An anecdote: we had a meeting with a guy who worked at a large company with a philanthropic streak. They provided, free of charge, a "dashboard" for planning, along with free training and tech support to any non-profit that wanted it (it cost considerable money otherwise). It was simple but very powerful, allowing you to do sensitivity analyses on projections to determine which courses of action would result in the best returns - both monetary and any other metric you wanted to put in (i.e. the social goals of the project).

It was like he was selling popsicles at an ice rink.

We ran into a very similar issue with Urbantastic. We had a web service that was very effective at getting small things done for non-profits: it's called micro-volunteering. There's no supervision required, you just write down what you want and someone always did it.

When we founded Urbantastic we thought the challenge was going to be in getting skilled people to help out for free. That was not a problem. The problem was that we'd go up to non-profits and say: here's a machine where all you have to do is post your todo list, and people will cross off items for you. For free. And we never got uptake.

People lined out the door offering to help, and almost no one took them up on it. Despite our offers to walk non-profits through it, and despite the recent funding cuts which meant that they needed all the help they could get.

I'm not saying that Urbantastic is perfect, but in our pilot cities this was overwhelmingly the result, and I still can't think of any incremental change that we could have done to get the non-profits engaged. A big part of it was that most of them were still uncertain about the whole email thing. It's not an exaggeration to say that some of them didn't know how to use a spreadsheet.

With our fancy web 2.0 ajaxy website, we felt like we were giving out iTunes gift cards to the lost tribes of Papua New Guinea. They didn't value it because they weren't even close to being at the point where they could use it.

I care about social good - I wouldn't have founded a social venture if not. And twice now I've been floored by the state of the non-profit world. Again, 10% of them are brilliant, but the other 90%... It's a big problem, and it's not going to get better by pretending that it's not there. That world is amazingly backwards. And it's saddening to see such important mandates being handled by such ineffective organizations.

My advice to anyone here planning on doing a social venture: drop backwards compatibility with the non-profit world. (one giant caveat: working exclusively with one or two of the few clued-in orgs might work).

Green and fast
I agree on XMPP, but there's a certain amount of pressure to keep this working entirely inside the web-stack as much of the blog-community (and especially the Wordpress community) relies on fairly limited shared LAMP hosting, where XMPP running in the background (or anything else, for that matter) just isn't available.

Of course, the cleaner solution is to make this XMPP "inside" for thos who can use that, and then make a XMPP-to-HTTP frontend for those who can't. But on the other hand, there's a good point in keeping things simple.

I see how that sentence is ambigious. I meant that you have it correct. The two key elements being "short term memory" and "items (variously defined)".

This article thinks it applies to long term memory, and most people don't realise you can 'hack' this by chunking 'items' into bigger 'items' (e.g 7 two digit numbers have 14 digits total).
