You're not missing anything. I don't want to knock the author because there's a lot of good stuff here that is well-worth reading but in this case I think he got a little carried away and missed the obvious, simple solution.
Just so I'm clear, you're saying a neat idea should beat a neat app?
Hey Matt! ;-)

I was thinking of another instance where this is noticeable: In a certain moving-mesh hydrodynamics code, the author was forced to use integers instead of doubles to perform intersection tests, because the "uneven" precision of the floating points can give the wrong answer to which side of a face a point is on, which leads to errors in the Voronoi tessellation.
I do the same. zoneedit.com is a free and very easy way to do this. Register a domain and use zonedit for DNS and email forwarding/filtering.
I feel bad for the celebrating Americans who seem to believe that terrorism is something caused by Osama bin Laden and that it would magically go away now.
Thank you for the equally detailed response. I apologize.

Did you fix the problem? I don't know how I'd solve it.
I can relate to programming not being fun anymore. After my startup was finally bankrupt I just couldn't get myself to sit in front of a computer anymore at all.
I did a two week bartender crashcourse and did that for 3 months.
Interesting, but actually it's no longer the case that fixed point math is faster than floating point. Certainly GPUs are a lot faster at floats than ints.
The prize is a symbol that, like it or not, sets precedent for the recipient's future behavior because this person sets the precedent for the everyday man. Especially with the peace prize.

Secondly, hes a leader. Not only that, hes a liked leader. Being the leader of the world`s leading superpower, his reaction will set the tone for the rest of the country, if not the world. By not addressing this particular issue he is portraying himself as nothing more than a messenger of good news. By being implicit about this, he is playing it safe (for the upcoming elections, no doubt).

I like him. Its not too late, he can go on the air right now, take charge, and address the issue.

Additionally, Americans celebrating the death of an individual like they just won the Stanley Cup is no better than when Iraqis took to the streets dancing after killing Americans in Iraq. This alone is a sign than the likes of Osama have succeeded in bringing America down to their level. I hope people realize that and not continue with these `celebrations`.

FYI: If it matters to you, I'm a Canadian.

Although, it occurs to me that perhaps Americans do feel very relieved and thus the celebrations. But I would only expect this reaction from a people that has been oppressed like the subjects of Saddam Hussein, not free and capitalizing Americans.

True, a good doctor doesn't diagnose neighbors for fun, but she does read medical journals and keeps up on the latest in her specialty. And would you trust an auto mechanic who didn't change the oil on her own car?
I'm going to rewrite and "streamline" this whole article. Juice it up a bit, if you will.
> So, many times a week we would wake up, see an instance dead (all critical processes locked in D-state), call Softlayer, and spend hours (literally) to bring it back up.

Wouldn't keepalived or heartbeat help with failover? If I see an instance died, I would delete it and start a new instance with a latest backed up image. I assume it would take ~15 minutes compared to relying on the support.
The chance of a party with 1% support getting 300 or more seats out of 600 is roughly on the order of 0.04^300.* This number is so small that you're probably better off worrying about a literal biological virus that turns people into fascists.

*The factor of 4 comes from the rate of growth of the central binomial coefficients.
The day Twitter reports MAKING $50 million dollars rather than SPENDING $50 million dollars will cause celebration on the streets filled with champagne and delight...until then, they're just a giant spam channel with a lot of VC
Antimatter is definitely ridiculously dangerous stuff in macro quantities.

Though strictly speaking, from a bomb-building point of view, it would be very difficult to design a weapon where matter-antimatter mixing happened more or less completely and simultaneously. Otherwise you "merely" have a series of uncontrolled multi-megatonne explosions in an increasingly large area, instead of a single multi-gigatonne explosion.
You have it exactly backwards. 100 factorial cannot be represented by a float (or double, or long double)

100! = 9332621544394415268169923885626670049071596826438162146859296389521759\

000000000000000000

This is 2^(524.765) > 2^32 or 2^64 or 2^80 or 2^128

Note that "floating point" is commonly used to refer to 32-bit or 64-bit or 80-bit representations.

Floats are for games (with caveats), and possibly engineering, while purer math needs arbitrary-precision representations that are too slow for games and many simulations.
1.0/0.0 has to be handled somehow.

Yes, by raising an error [1]. Or whistling innocently and pretending it's not my code while leaving the room.

handling it as "+infinity" has a 50/50 chance of being "correct"

It has zero chance of being correct because infinity can never be the result of any arithmetic computation. Infinity is not a number. Infinity only appears as the result of evaluating limits, an operation which is not arithmetic.

The Craigslist user experience is just fine, IMHO. Rather than trying to improve what's not broken, how about finding a way to get rid of the SPAM and eliminate the scams. When it first started, Craigslist was great because there was a community of trust. As it became popular, trust disappeared.
That's an uncompressed Bloom filter with a single hash function. To get a false-positive probability of p with a single hash function you need 1/p bits per entry.

But that's the uncompressed filter. It compresses way, way down: to about 8 bits per entry. That gives 400KB of data, still with a 1/1024 false-positive rate. Much better than 3MB.

If you consider (uncompressed) Bloom filters with arbitrarily many hashes, the best you can do for a false-positive rate of 1/1024 is about 14 bits per entry.
You missed the parent's point. It's not the money of Silicon Valley that helps you, it's the constant brainstorming of ideas. You will be exposed to so much collective experience that your product will improve. On the surface, it will seem to be magic, since really it's the same idea you had when you lived in the middle of nowhere.

Except you benefit from talking to people with deep experience. When someone here tells you "have you tried putting this button on that page?", it's because they did it and it doubled your traffic. Experience of what works and what doesn't circulates so much faster in Silicon Valley.

Why would you want to be disconnected from the flow of ideas? If you think online forums are a substitute, they are, but with a time delay.
Spam Gourmet is good for the second case. blah.myname@spamgourmet.com gets forwarded to my real email. I can configure a maximum number of emails that will work before the alias stops functioning.

You are feeling screwed? Because it was disclosed you entered a competition? What were you going to do if you got in, wear a balaclava and talk through some sort of voice altering device to hide your true voice?

And if you don't get in are you afraid that people are going to ridicule you for the rest of your life because your name was in the to list with 500 people?

I appreciate that TC made a mistake, and you would think they might have gone a bit further in preventing this sort of mistake, but I think we have all suffered far worse invasions of privacy than this (half the people on the list probably tweeted that they'd entered anyway).
The military don't like antimatter weapons because they are fail-dangerous. They require active stabilisation.

If a nuke fails, nothing happens. If antimatter containment fails, your entire arsenal of antimatter weapons go up at once.

For a similar reason, nitroglycerin is strangely unpopular for both civilian and military purposes.
I'd like to master Python. Mainly just because it is so powerful and useful for the kinds of things I need. I wouldn't mind mastering C simply for the badass-ness of the language, but going that low level isn't what I enjoy. Python allows for quick project turnarounds and is, in my opinion, a beautiful language.

Our primary competition will be ticketing systems that decide to create the functionality of in game seat upgrades. However, such ticketing systems like Veritix, Outbox and Pacolian will be fundamentally limited in that any upgrade functionality they create will likely only be used within their family of venues (AEG being the largest with 105 venues) and they are unlikely to license to their competitors or their competitors to pay them money for this add on features. Our goal will be to create groundswell from the fan perspective.

As Abel said, the 800 pound gorilla in the room, LiveNation/Ticketmaster (around 3000 venues) is having enough trouble just trying to put out daily fires, thus effectively stifling any innovation designs they may have.
Of course, in particular since in most cases, one must communicate with the GPU using 32 bit floats. (I'm going to guess that this is changing, though.)

In our case, we were doing a port of a PC game to PS2. We were chopping up the PC levels to try and fit them into memory (~16MB).

Unfortunately in chopping them up, they were not re-centered. So, even though one of these new smaller levels might not be large, if the whole thing was far from the origin, madness ensued.

El-cheapo solution: pre-process the level geometry to centre it again.

Not elegant, but expedient.
Does anyone have any contacts at Softlayer?

This could be a great opportunity for them to explain how their business works, and give some potential customers insight into how they're working on things.

Or... it could be an opportunity for a marketing-speak filled cover-up which would damage their credibility further.

So, for the uninformed peanut gallery, beagle3 is just plain wrong. Probably not intentionally, he's likely also fooling himself. But you locked him in a room and measured his food for him and really only fed him 1200kcals per day, even at a fairly sedentary level of exercise, a 220lb man would lose a lot of fat mass over several weeks. And no beagle3, human bodies tend to be very greedy with calories and do a good job absorbing them regardless of what you smell.

What likely happened is that reducing carbs reduced beagle3's appetite and he ate less. Unless...

...unless beagle3 has a magic body that has never once been seen in any controlled experiment. But he probably does, since every dieter who has problems believes they have a special body that science can't explain. So they buy a book and a program from someone who tells them what they want to hear. And if their guru is on their game they sell very very expensive supplements.

Because its a well known scientific fact that the first law of thermodynamics applies to everything in the universe except a disgruntled dieter.

I am an astrophysicist, and I deal with this issue directly. In my simulations, I do deeply nested Adaptive Mesh Refinement calculations. ...

...In one of my "stunt" runs, I ran up to 42 levels of refinement inside a box; this means that the dynamic range between the coarsest cells and the finest cells was 2^42.

You assume that only 8 of Jeff's acquaintances bought SSDs. It might actually have been 8 failures out of 100 purchases, for example.
The thing is, all our cloud instances were redundant so SL downtimes almost never caused real service disruptions on the site. But when one instance dies, there is a huge chance that other one (two, five, ten) will die soon as well. As for the automated kill/deploy scripts - really often even their own cloud-related portal features don't work (like when you try to restart/reset an instance and their APIs and portal just time out, etc).
This article lays it all out, interesting read.
In general, quite sound advice. But, to follow this analogy, you don't always need a top chef. You may just be working a hot dog stand, a McDonalds or a college Chinese joint. Not every chef is headed to a 5-star restaurant.

The key on race day is to get as much water as your stomach can handle -- one coach (Benji Durden) recommends about a quart of water 1-2 hours before the race, and then almost a half bottle every 6 miles or so. That's a lot of water when you're trying to run 5:30/mile pace!
The Most Open Letter Ever
Actually, it sounds like you got it perfectly. There is legitimately a way in which he's going "backwards", it's just not the way you would naturally think of if I just told you he's going "backwards". The backwards-through-time thing is one way of reading the math, but it doesn't mean what you think if you just read what the English says. Antimatter is way less interesting than "backwards in time" can make it sound. It's interesting, but not "kill your grandfather before your father is born" sort of interesting, just "fun particle physics" interesting.
I love those features in PHP, especially OO and anonymous functions as a way to organize my code, make it more readable and maintainable. However, I'm not using them strictly in a conceptually pure way. OO was meant to lead to massive inheritance schemes, and PHP is just not a suitable environment for that paradigm.

The reason why most PHP devs don't go off on massive Java-like inheritance sprees is PHP's execution model. It's strictly request-based. For every request, PHP code creates an environment to service it, and then everything gets discarded. This is one of the strengths of PHP, actually, it makes PHP apps stateless in many respects. However, this also means that it is unwise to build computationally wasteful structures like extensive OO schemes - at least for performance-conscious production environments. Contrast this to Java or ASP.NET apps, for example, where the cost of initializing massive OO frameworks is offset by the fact that they stay intact across requests.

So I believe OO features are very good and important for PHP, as long as developers keep the computational cost in mind. Also, closures are awesome.

she does read medical journals and keeps up on the latest in her specialty.

1) I don't know much about doctors' scheduling, but I've known a few that seemed to schedule a batch of patients, then hours for paperwork, document review, and peer review/help. So I wonder how much of this happens in their "free time".

2) There's a difference between reading up on new technologies versus creating a project and seeing it through to completion. Similarly, there is a difference between reading medical journals (study) versus seeing patients (practice).

would you trust an auto mechanic who didn't change the oil on her own car?

Absolutely. That's a very simple job, and if my mechanic can have it done for $20 at Walmart while he shops, it's well worth his time. If he's a good mechanic, he bills at, what, $70+ per hour? By the way, the mechanics I've known tend to drive inexpensive, late-model cars, and get rid of them after a few years. Why? Because they don't want to fix cars in their spare time.

> They HAD to beat the iPad 2 release date at all costs.

I doubt they had to. They chose to, and blundered with the entire world looking at them.

If I were Moto, I would have red-lighted the project some months before deadline, when it was readily apparent that Google wasn't going to deliver a quality stable release on-time.

Competing with the iPhone (and it's carrier exclusivities and high ASP) is one thing, but if you have shoddy product, the iPad is going to wipe the floor with you unless you really offer something unique (ie, eee transformer looks interesting).

Singapore does invest heavily in education and with great results. Since the discussion is about prison population and expenses, though, it's worth mentioning that Singapore's correctional regularly employs executions rather than paying to for the housing and correctional officers necessary to hold a prisoner for decades. Also, unlike the US, where executions are extremely difficult, controversial and expensive, they're efficient and cheap.

It's hard to dispute the economic success of Singapore's model, but it's not one that any western countries could or would emulate.
We know that dark matter cannot be baryonic matter (atoms) for two reasons. First, models of the big bang that have been confirmed by experiment closely bound the total amount of baryonic matter in the Universe. Second, dark matter doesn't seem to behave the same way that baryonic matter behaves (normal matter clumps, dark matter doesn't appear to do so).
Yes, but not just an idea. Assume each entry is scored with equal weight in terms of the business model, functionality, pitch and team. If functionality=0 (no working app) you may limit the maximum absolute score to 75, which may in fact be greater than any other entry. If it would advisable to purposely not make something that works would depend on the competition criteria.

Interestingly enough, the latest update [4 months ago] to ometa for scheme has the following description:

Empty space isn't completely empty, even between galaxies. There are traces of gas, almost entirely Hydrogen, between galaxies. If there were entire galaxies made of anti-matter then the areas where their clouds of inter-galactic anti-gas contacted normal inter-galactic gas would be rife with emissions due to annihilations. The amount of matter should be enough to be detectable even at tremendous distances.
perhaps its expected as an extra convenience?

With no disrespect intended to the doctors and researchers who comprise the medical field, I find it interesting that those closest to the field show the most concern over interpretation of sequencing results. As an educated medical layperson, I still believe that companies like 23andMe should be able to offer statistical interpretation of sequencing data. At the most, I could accept a required disclaimer, but it is a statistical fact that certain studies have associated certain SNPs with certain conditions, and I should have as much of a right to know those facts as I do to read the raw sequence of my DNA.
It looks that way. I've been playing with it and I've found two ways to actually store and reuse scripts though:

1) Use loadstring() to compile and run a script from a Redis key.
EVAL "return loadstring(redis('get', KEYS[1]))()" 1 foo

2) Set a function as a global value, and call that.
EVAL "myfunc = function() return 42" 0
EVAL "return myfunc()" 0

antirez said in his previous post (http://antirez.com/post/redis-and-scripting.html) that storing scripts has some problems with regard to Redis Cluster, though.
You should generally treat any slippery-slope arguments — whether from your own mind or others — with a lot of skepticism.

Just about anything can be said to be a slippery slope toward just about anything else (see also: Godwin's Law), so which slippery slopes you believe in has more to do with your own biases than any practical concerns. Unless the connection is very clear (which the connection between "remote execution with local display" and "DRM" is not), arguments like this will rightly be met with a lot of skepticism.

The main takeaway I got from Joel's essay was that companies whose focus is software need to hire better programmers. Maybe the 99th percentile is extreme and it should have been 9th. But it isn't difficult for me to imagine that the vast majority of programmers work at companies whose focus isn't software, and whose work is mostly things like connecting to legacy telcom systems. That vast majority of programming work doesn't need to be done by crack teams of algorithm gurus.

If your company is working in something more performance bound, such as CG animation, then you probably do need top programmers. Salary won't be the only way to get them, though. People with a true love of CS probably get bored with all the database driven CRUD apps.
