"When I think about every big leap that happened in my career, it was always because of 'someone I knew.' Always friends of friends. People in some position of power who I kept in touch with, did favors for, and got the same in return."

"You can break someone out of their drab life as an assistant sales rep for a manufacturing company. You might be the coolest thing that ever happened to a teenager going through an unpopular phase. You can give them a mission!

If they’re a fan of your music, invite them over for pizza to spend a night doing a mailing to colleges."
And you are over-simplifying it. In Windows, install = double-click setup.exe. In Ubuntu? ... Wait, what was that again? I didn't get it.

For those who have been using unices for many years, it is difficult to remember the challenges of a switcher. I've been using Linux for 12 years, but I have constant reminders, because I'm a CTO, and have to support the end users who are coming into a new OS environment. When you, who have all this stuff in your head, trivialize the new users legitimate challenges, you are part of the usability problem, not part of its solution.

It's a valid question. The browser is the gateway to most of the applications I use in a day. Closing it down would be like shutting down my computer whenever I step away from it.

I don't disagree that applications (and operating systems) should start up quickly, but it hardly seems like a critical complaint. And, as much as I appreciate improved Javascript performance, the differences are not that significant in the real-world.
Interesting thing is we all (if we were to delve deep enough into ourselves) have Aspergers to some degree.
Never mind the usability desaster that the GIMP represents for anyone who is accustomed to PS.

In the interest of fairness...I just bought Adobe CS4 Web Premium (with Photoshop, Illustrator, etc.). I've been working with the GIMP and Inkscape for a good long while, off and on, and I'm still finding Photoshop and Illustrator to be incredibly hard to use and obtuse. I've been watching video tutorials, reading the docs, searching the web, and tinkering, for a couple of weeks now, and I'm still nowhere near as productive as I am in GIMP or Inkscape. Partly this is just that the Adobe products do more. This is an acceptable cost, to me, but I still find myself feeling grouchy a lot of the time because things do not work as I would expect (not just "as the GIMP or Inkscape would do it", but also in terms of discoverability...for example, sometimes I accidentally break my workspace, or whatever it is called, and can't figure out what I did or how to fix it; you can't undo workspace changes, as far as I know).

Take it all with a grain of salt, as I'm a barely functioning idiot with quite a few products that are supposed to be easy to use. iTunes, for example, is a nightmare for me; I always end up deleting my whole collection either on the device or on the computer or having something else go totally amok and I have to reboot into Linux just to recover all of my data. So, maybe Adobe software is "easy to use" like Apple software is "easy to use", and I'm just an idiot.

Stability of the Adobe stuff also leaves a lot to be desired. It's kinda like Inkscape a couple of years ago, or GIMP ten or twelve years ago (or during the 2.0 beta years). Sometimes weird things happen and it just freezes up. This may be the newer Adobe stuff; I'm usually watching a tutorial video when it happens, so maybe Air or Flex or whatever is to blame, rather than Photoshop or Illustrator. But it happens a lot when I'm watching those videos.

Walmart is not that smart.
He's not selecting each row one-by-one. He's getting 48 records back using two queries. The first query gets the 48 id's of the most recently updated posts. The second query selects the entire row that is associated with each id:

1) select top 48 Id from Posts

2) select * from Posts where Id in (<id's selected from previous query)

Unless the second query is 'abstracted' into 48 individual queries (which would make for an interesting abstraction-article in itself) your accusation is completely baseless.

I think Jeff's notation in the SQL queries were a bit confusing, but if you actually read the article his intention is clear and his point is valid. I'm baffled by the retaliation here on HN. Please rebut me and restore my faith in the HN community.

Thank goodness that Hitler was driven more by revenge than by cold common sense. He diverted massive resources from projects such as this one, toward building more bombers to get back at the Allies for bombing the hell out of German cities. Consequently, a lot of really cutting edge stuff never made it off the planning table. And that's a good thing.

Yes, even for web applications, bitwise manipulation will come in handy at some point.

Personal anecdote: I recently had to combine two arbitrary unsigned 32 bit integers into one unsigned 64 bit integer to make a unique ID for an index. Not sure how I would have done that without bitwise manipulation.
How could they miss the classic. Swap two integers without a temporay var:

a ^= b
b ^= a
a ^= b

I'm just saying it's an unreasonable definition to say that someone who works out 6 days a week is automatically a freak or a fitness junkie. As in anything, there is a line where the freaks are, and you've chosen to draw it awfully close to someone who never gets any exercise at all.

Vegetarian here, former meat eater. When I eat fake meats it's not because I want to pretend I'm eating meat, but because I like the taste or texture. I like to fry tofu in a frying pan and simmer it with kung pow sauce - that doesn't mean I wish it were chicken.

Products are labeled "mock chicken" or "veggie beef" to help in recipe substitution, too. It's a code that this form of processed veggie protein is suitable for recipes that call for ground beef, or taco meat, etc.

PS - when I first converted I loved Boca burgers because they tasted just like McDonalds burgers. Now I hat them... because they taste just like McDonalds burgers.

I'm not sure I fully get the explanation from your EDIT. If you had a single scope resolution operator ::, classes and namespaces should share the same hash and lookup. A class is, fundamentally, a namespace.

namespace foo;
function bar(){echo "func\n";}

class foo{
static function bar(){echo "func\n";}
}

Should be equivalent as far as invoking them is concerned.

To start off, I recommend that you get more practical-oriented books which contain lots of exercises. There are actually some books which try to explore discrete math using C or Mathematica/Maple. Those might make the subject a bit more interesting and concrete.

I've found that (at least with computer books), for me the mindless visual quick-start texts are best to begin with. They make it more fun to explore the material even though the books have less "meat" for your buck. Even though I am advanced enough to sit down with a manual and understand it, these books are much more motivating for me.

Often when trying to sleep after a long period of deprivation, it feels different, in that I can actually feel individual systems switching off -- I might have music playing through my head but be incapable of conscious (subvocalized) thought, or vice versa, but if I'm aware of anything other than breathing, then I'm far from sleep. And, after a few hours of lying in bed trying to sleep (knowingly without success), I might suddenly feel wide awake to a greater extent than what would be expected from normal sleepiness/wakefulness cycles.

This finding jibes well with my experiences.
I am bit confused, since I am pretty new to this voting system at YC. Unless you have something useful to say for the topic, you just cannot leave a comment saying you like/dislike it?
Computers are basically free on a small scale. Most of the cost is electricity to run them and various other overhead and management. As a freelance programmer and linux sys admin, I have so many servers, desktops, older laptops, and etc that customers have given me free, that even though I only keep the working ones, right now only one person at a time can fit into my office.

I'm not sure what "the solution" is, or even if there is a problem. But I think that if you have old unused computer hardware, the more profitable thing you can do is simply use it in your business directly and thus avoid buying more new stuff later on.

"Because at this moment science is very far from solving human aging problem, and significant investments wouldn't likely help much."

A lot of very intelligent people think otherwise. Do you have a good justification for such a position?
Absolutely! Some of the examples, depending on the core architecture, could benefit from a table lookup, but all are good tools to have in the box.
A lower population means less need be spent to provide health-care services per individual. Why? If the average cost of 300 million people was say 5k/year why would the average decrease when only caring for 30 million people?

The US has ~10x the population density of Canada.

United States — Population - Density: 31/km2
Canada — Population - Density: 3.2/km2

And the population density of a state does not really correlate with its healthcare costs so I think it's a pointless comparison.

PS: You seem to be confusing total cost with average costs.

Well, in normal waves, particles don't travel either. Water waves move up and down while the wave moves forward. Compression waves like sound move air particles back and forth, but in general they go back to where they started from. Light is weird because it's both a wave and a particle.

But you're right, this is just a trick to make something look like a wave that's travelling faster than light. It takes the same amount of time for it to get to you, but when it does, it looks like it's travelling faster.
WARNINGS:

- as you excessively bit-twiddle you may end up creating nonportable code in some languages across certain platforms

- surprise...you cannot manipulate a single bit of data...on most platforms the smallest bit of data you can manipulate is a word. so you may actually be creating SLOWER code while you are making BRITTLE code

most of the time, bit twiddling is not worth it. sometimes it is, and it is fun.

Thanks, that's a good question and comment. I'll try to write another part of the article with applications to these hacks! There are plenty in embedded engineering, kernel programming, cryptographic algorithms, space efficient data structures, fast image processing algorithms, and in plenty other computing areas.

To answer your question, why you'd want to set/unset the right-most 1-bit, suppose you have a space efficient 8 bit data structure that represents 8 devices. Each bit represents if a device is on and off. And you want to turn off the right-most device. Then you could use that hack. Or for example, you want to linearly turn on devices from 1st to 8th, then you can just turn on the rightmost bit eight times, and turn off in the same manner. Or you could have some crazy device that puts data at some memory location and waits you to clear the rightmost bit before it puts new data at that location. Or you have a number system coded in your byte in such a way that rightmost low order bit is always the sign (or some other craziness).
