Gray code was used as long ago as the Atari 2600 game system, designed in 1977. The system's clock for drawing out sprite graphics pixels counts in Gray code internally. Why? Because a binary adder could have too long a propagation delay. To increment 01111111 to 10000000 requires seven carry operations which would not always complete within a single clock cycle. (A modern ALU has tons of transistors to compute all those bits in parallel, but the Atari 2600 mass market game console did not have the budget for that many transistors.) Gray code was the solution. It always changes only one bit to increment a counter so the operation was guaranteed to complete quickly.
What about the issue of car thieves in general? From the sound of it, you are required to keep your keys inside the vehicle. The founders basically said "the keys will be in the ignition". Is there no locking component of any sort included in the getaround kit?

Doesn't this essentially make the application a directory of easy-to-steal cars for potential thieves?

proliferate the notion that homosexuality is in fact a choice, in that homosexuals can supposedly chose to control their sinful desires

There are certainly a lot of behaviors that we're (as a species if not as an individual) predisposed to, that are viewed as socially unacceptable. For example, the benefits in a Darwinian framework of extramarital affairs are quite well established. It's to a males genetic advantage to have as many sexual partners as possible, and generally men do have such latent desires. Yet society condemns those who act on those desires, even though they're perfectly natural. Why can't we say that homosexuality is similar: something that an individual may be predisposed to for whatever reason, but if he wants to avoid society's scarlet letter, he must repress those desires? [1]

Of course he's also not giving any explanation for exactly why homosexuality is supposed to be sinful in the first place.

I'm not going to dig up citations for this because I'm not interested in proving it. Suffice it to say that there is sufficient text in the Christian Bible that someone who builds his moral codes from what he, personally, reads in its pages can reasonably come to the conclusion that homosexuality is a sin. [2]

[1] Not that I believe that a homosexual should have to repress those desires; I'm merely arguing that this is an internally consistent moral system.

[2] I also acknowledge that there are places in the Bible that might contradict that, or at least temper its severity. My point is that a reasonable person, weighing many passages in the Bible, might come to that conclusion.
"If the data grows past the capacity of one server, then the tables in the database will have to be partitioned across computers. To avoid JOINs having to cross the network in order to get data in different tables, we will have to denormalize it. Denormalization stores all of the data from different tables that one might want to look up at once in a single place. This makes our database look like a key-lookup storage system, leaving us wondering what other data models might better suit the data. "

I have a question here. Denormalization increases redundancy of data, thus also increasing space requirements. So how is denormalization a solution to low server capacity?

I didn't mean deux ex machina. You can provide the information and let the audience infer the result, or you can explicitly show the result. As you build the storyline and subplots, judiciously allowing the audience to interpret what happened at intermediate points in the story or at the end can make it more interesting than simply laying it all out.
Many congrats on the preview release.

In my opinion, this is a brave move from the team -- acknowledging that the SproutCore approach from the past four years needs to be ditched in favor of a brand-new codebase, and one that's a small fraction of the size (both code and API-wise) of the previous SproutCore.

Even though it's not recommended right now, I imagine that in due time SC 2.0 will also be recommended for "desktop-style" web applications, and when that happens, it'll be a force to be reckoned with.

Everyone has to pay $10 a month to the film industry.

We already have the IP tax. In my country, it's essentially a value added tax on all digital mass media, regardless of use. The money from that is lumped in with the money from concerts and from playing radio in public, and goes to an entertainment organization that then distributes it to its members and partners as it sees fit.
The author should use something like "crawl data" instead of "index". An index is the end result of analyzing crawled web pages.

It's a cool idea though because Yahoo sucks up a ton of my bandwidth and delivers very little in SEO traffic. On most of my sites now I have a Yahoo bot specific Crawl-Delay in robots.txt of 60 seconds, which pretty much bans them.
I'm understanding the term "hostile reading" as Card defines it in the above quotation. A hostile reader is one who approaches a book skeptically or is forced to read it (in the sense of being required to read it to complete a class). A hostile reading is what he does.

And here, inherently, is the issue with this model of advertisement. IMO, if a user can be too "savvy" to participate, it isn't a good advertisement model. Anything that relies on lack of knowledge or "savviness" isn't very solid.
Hm, if people estimate the popularity of something by the relative frequency with which they encounter it, and if they end up seeing only stuff that's tailored to them, then they may start believing that everything they like is mainstream and "correct" as a result. People may become less tolerant of stuff far outside of their comfort zone and end up becoming more polarized, which is not what I had imagined would be the effect of the internet.

I was aware of all of the things you mentioned when I made my comment.

You're conflating a whole mess of things: "conservative", "Republican" and "Libertarian" are all different. The only one of those three that can Thiel can be meaningfully labeled is libertarian. He's a couple orders of magnitude further away from Republicans than most Democrats. His political views are radical and outspoken, but "Republican" they are not.

Second, it's silly to assume that someone as prolific as Thiel does everything for an ulterior political motive (investing in Facebook, Zynga, life extension, running a hedge fund?) or that even those that do conform to some pre-fabricated ideology. His views are sufficiently distant from the norm that I find it overwhelmingly clear that he thinks independently on separate issues. If you want to label the lump sum of a person's ideals "political", then sure, they're "political", but that definition isn't particularly useful. The more conventional definition of "political" would be "having to do with governmental politics", and if anything his ideology is anti-political.

Your comment was ad hominem -- you made no attempt to actually draw a connection between this program and his purported political agenda and instead chose to go after the fact that he donated to republicans and gave interviews to the Cato Institute. That's what was disingenuous. That he's a libertarian is obvious; that this act was part of some effort to undermine the universities because of his "conservatism" is not.

contrarily to what I'm reading here, I think that it is a good idea that the trial goes on. The point is not that a best estimate was wrong, but rather that the conclusions could have been steered by political pressures, which is actually not unlikely, considered the history of man-made or man-facilitated disasters in Italy (e.g. the Vajont dam).

I believe that the purely scientific advisors will be cleared at the end, but bringing everyone to trial is inevitable as the firt step. ("inevitable" in standard italian judiciary practice, that is).

Anyone play the real-estate market?

A great leading indicator of 'selling a home' seems to be 'european airfare' and 'florida apartments.' So here's what you do. Take out google adwords for these searches, offer 'great deals' in return for your zipcode and email address.

Then you can use these addresses to send inquiries about home sales and get in on sales before they hit the market!

There, go make money.

P.S. If this actually works, be nice enough to let me know :)

It's the dirty little secret of the "we hate tabs crowd" - they have to keep everybody in monospaced fonts otherwise their conspiracy to force programmers to repeatedly bash their space bars falls apart.

All joking aside, the choice of font should reflect what it is that you are trying to do with the text.

In theory a serifed font is more readable if you are reading the entire text, whereas a sans serif font is supposedly better for skimming through looking for something in particular.

(so on a web page with an article, the article text should be serifed, and the sidebar menu should be sans serif)

An application of this might be that if you are printing out a codebase in order to read it in entirety for the first time, you should use a font with serifs.

whereas if the codebase is relatively familiar to you, but you are printing it out and going bug hunting or reviewing the code, use a sans serif font.
This might not be the answer you're looking for, but.... I am the sole technical person and am pretty much responsible for all technology for my library. I actually don't get much of anything done on any given day. But most importantly, I maintain people's confidence in our systems and assuage their fears so that everything continues as normal. I am lying to them half the time (our downtime is almost always unexpected issues in "the cloud" and all we can do is wait. When implementing new systems, if I feel they're good, I assume it'll work out and promise success with a hiccup here or there), but it's necessary and important part of keeping us going. Simultaneously, I have developed several apps on the side.

I guess the point I am trying to make is that productivity is relative. It's what matters to you and your company. If features are important to your company, then you should be knocking them out. If you're a university with 15,000 students and thousands of full-time employees, not doing much and making sure people still trust you is more important.

With that said, I have recently been worried about my skills and have been working hard to be sure I'm keeping fresh. I used to get hung up on design, but lately I realize I can code up a horrendous site but 100% functional site, and make it look pretty later - saving myself hours and hours of work. Also, I'm working on writing tests so that I do not spend much time tracking down regressive bugs. It's amazing how useful a comprehensive test suite is to determine your next task, ensuring that you regularly press forward.
I've covered every suitable vertical surface within easy reach of my chair with whiteyboard[1]. They also make big ones (3.3x6) that you can slap on a wall. It's cheaper than IdeaPaint, way easier to apply, and it looks like it's smoother (although still not as smooth as a regular whiteboard).

My whiteyboards do suffer from "burn-in," but that's easy to fix: just scribble over the "burnt-in" writing with another dry-erase marker, then erase immediately. The solvent in the fresh marker picks up the old "burnt-in" pigment so that you can erase it. This trick also works for getting permanent marker off of a whiteboard.

Taking your argument one step further ... At what point are the number of earthquake deaths more economically costly than repeated unnecessary evacuations? Perhaps 300 deaths is worth keeping hundreds of thousands at their workplaces over an extended period of time.

Consider that millions of Americans use public roadways every year at the cost of 30K fatalities.

I wonder if the politicians made the correct economic decision but the wrong ethical decision?
Nice suggestion and thanks for the compliment!

The inspiration for this work is the Regexp::Genex module from CPAN: http://search.cpan.org/dist/Regexp-Genex/ -- though it uses a random-walk approach for character classes, instead of enumerating all possibilities.

regex-tdfa was only really used for parsing regexes, so it's certainly possible to find duplicates. That said, piping the output to "|perl -pe 's/.*\t//' | sort | uniq -d" is quite usable too. :-)
Yeah, I followed that advice at one point. But I find in practice a plain English comment can be much more helpful than a function name. For example, from the code I linked:

# Check too many lines. Count number of lines without a comment.

If I were to turn that into a function name I would either have one long ass function name or (more likely) I would cut out several words and lose a lot of readability and clarity.
Yes. The list is generated lazily and ordered from shortest to longest, though, so piping the output to "|head -n 100" will terminate rather quickly.

The ([String] -> IO [String]) API also generated a lazy list:

http://hackage.haskell.org/packages/archive/regex-genex/0.2.0/doc/html/Regex-Genex.html

so one can take only part of the output like this:

Regex.Genex> fmap (take 5) (genex ["([abc]+)\\1"])
["bb","cc","aa","bbbb","cccc"]
The short story was much better.

There is speculation that the full length novel was ghost written. Essentially somebody asked Card a bunch of questions about it, and he didn't know the answers to any of his questions...
