I really do look forward seeing what happens with Bingo Card Creator, or whatever you do, once you're on it full time. Good luck.
I think a faster ramp-up would be better. I just finished 19, I see the solution to 20, and I kind of feel like it isn't worth the time to see 21. Maybe you could limit the game to three levels for each new concept? The comparison to Portal is apt, but there weren't many routine levels in Portal. I think you could cut the number of levels by half and still retain all the puzzle-solving challenge. It would just be more concentrated.

Still, this is really good. I don't bother with flash games very often, but I'll be sharing this link with a few friends.
If only I could order my bagle like this at a coffee shop.
Try not to use wait() like this.

There was recently committed writeSync, statSync, etc. that perform POSIX API calls synchronously.
Maybe your fans are old and you could clean them/lube them/replace them? Maybe you could disable the fans safely (might reduce lifetime or something, but maybe not kill it) if you watch temp.
It's a laptop, try using one of those little $100 fridges from Home Depot. Try putting it in there. That might work for you, plus you can keep something cold to drink close at hand too.
the query plan is traditionally interpreted, not compiled to native code

Actually, System R (IBM's pioneering relation database from the mid 1970s) compiled query plans down to machine code.
Have you considered buying a silent computer? I think it would be cheaper than an enclosure. Depends what type of power you need though. Mac Mini is good for this or maybe ATOM if you can get by with it. An easy solution I've used before is to stack a small wall of books in front of a loud device. Don't fully enclose it just make a little wall between yourself and the laptop. It may not erase the sound entirely but it will definitely smooth out the higher frequencies.

That's what I figured. Scraping might violate the TOS and would require an actual search bot/crawler/parser as opposed to simple API access. I was more complaining about the limits of Twitter in general; I think this is a huge step in the right direction, kudos.
I think the spare-time business is forcing him to be very methodical and it's making him tolerant of experiments that take weeks to run, and that's also influencing his judgement and the solutions he's finding.

Great game, very addictive. Did the performance get really slow for anybody else around level 10? Feels like a memory leak, events not being handled properly or similar are making the little guy slow down to a crawl after a while.
Probably involves a lot of peanut butter ;-)
Documentation for starters. There are a ton of hidden gems down there in the weeds, but until you really grok the whole system they are quite hidden. I needed to have a worker query its supervisor for the start args of all of its running children once. The info existed and eventually I found it (sys:get_status called on the supervisor and then pulling data out of some heavily nested tuples), but it was not a part of the standard supervisor calls and eventaully someone pointed me to the sys module; digging in here taught me a lot about how things work, but it is not easy to find if you don't know where to look. OTP is a lot like Rails, there is a steep learning curve but once you really understand how it works you can do a lot of very cool things with the available tools.
Bronze Age -> Iron Age -> Industrial Age -> Information Age -> Biotech Age -> Space Age ?
Do not ever disable the fans! It’s probably not a hardware problem with the fans. If it has a server OS running on it the bios on the laptop is probably not server friendly. Plus if the OEM had some kind of temp sensing application on the laptop to spin the fans up and down as needed the server install might have wiped it out. Net result the fans run wide open all the time making the laptop seem noisy.
Nintendo also has a lot more marketing to back up their choice of name.
Mr. X points out how they make money off people who forget, lose, or simply discard their gift cards. They also make extra money off people who are compulsively responsible about their cards. After all, the easiest way to make sure you use the card before it expires and "get your money's worth" is to make a purchase that you are sure will drain the entire card. The less sure you are about the remaining balance, the bigger that purchase will be. The same thing goes for getting all those damn gift cards out of your wallet after your birthday so you don't develop a spinal deformity from storing them under one butt cheek.

Ask HN: Rate our idea / site (Textbook Revolt)
http://www.textbookrevolt.com

It's a student to student textbook rental platform. Renters earn money by renting their books out (repeatedly) while retaining ownership. Rentees save money by paying only for the time they need the book (a semester).

We launched in 2007 as a textbook exchange platform. While it worked great in theory we've identified many of the issues that made the idea not realistically feasible.

That's how we came to the s2s (student to student) rental notion. It solves most, if not all, of the issues that kept a free exchange system from working. Plus there's plenty of upside for students on both end of the transaction.

It's tough to ensure a smooth transaction, but we feel we've made it dead simple to do. Thoughts?

I think it's important to recognize that the creativity/implementation distinction isn't going to be universal across all your skills, even within something as seemingly specific as programming or drawing. Maybe you have an easy time reasoning about mutable data structures, or maybe you are particularly able at capturing light and shadow. If you can recognize which things are strengths and deliberately extend all of the things you are good at into an overall creative vision - a cumulation of your ability that takes those strengths to the "next level" - then you'll go a lot farther than you will just trying to shore up the weaknesses.

(That said, you can become good at just about anything with carefully cultivated passion and a dash of smarts.)

The group's approach to build cognitive assistant might be on the right way. Rather than build standalone AI, the assistive approach encourages interfacing human brain. During the collaboration between human and the assistant, both will get better understanding about the other. We human don't need computer to work with emotion, but work by understanding our need and satisfy our need just in time.

Funny clip :-)

If they were powering it from a DC source, like a battery, that would be the way to go. However, it looks like they are powering the device with a separate AC supply. Connecting one AC supply to another -- synchronizing voltage, frequency, and phase -- turns out to be difficult.

The most practical method of doing so is by first converting to DC before converting back to AC. In fact, the interconnects that link the regional power grids in the US are high-voltage DC, because, among other reasons, that allows the grids to be unsynchronized.

The advantage of the simple sensor-and-switch approach is that one need not worry about synchronizing the replacement AC source with the original AC source. The downside is that the window for the switchover is pretty small.

What differences in CPU power management do you think there are between a server OS and a desktop OS? (Operators of server farms try even harder than laptop users to save power. Hot servers sucking down a lot of power require very expensive infrastructure. Reducing power consumption and heat production makes the infrastructure cheaper.)
I think "my laptop is noisy" is the symptom, not the problem. The problem is that you have a server in your bedroom. You can address your problem by renting a cheap VPS or low-end dedicated server. You'll never hear it or worry about temperature again, you'll have increased reliability, and you'll spend less of your valuable time keeping the server alive when you could be doing more important things.

Nope. A certain Mr. Goedel and I agree that certain truths are unverifiable and fall outside the realm of mathematics.

We committed to SQL Server a long time ago. It's served us very well and it will take a lot of effort to replace it. To keep up with increasing workloads we've had to purchase reasonably expensive hardware - I think the last server cost us almost $100k. The #1 bottleneck has always been disk IO. To compensate for slow disks you need to increase RAM and make big RAID arrays, both fairly expensive options compared to the Intel SSDs available now.

Upgrading our current hardware with only $10k worth of SSDs will add at least a year or two to the life of our SQL Servers.
It looks more like an alternative to Get Satisfaction and the like to me. Looks reasonably good from the screenshots. I'll give it a shot if there's a free version/trial version released.
I know that I would have loved to have a service like this that functioned when I was in school.

Can't quite tell how you are going to go about it, but it seems like this type of venture might have the best shot of working by focusing on a single campus at first. A lot of groundwork marketing to social organizations, academic clubs, whatnot in order to try and build a local community whose needs overlap to prove the model and then scale out. Focusing on a single campus or two would make the "ball rolling" phase much more achievable as well.

Also getting going before finals week when everyone is selling books for beer money so you have an "inventory" for the next semester or investing some money in common textbooks yourselves to lend out to get the ball rolling couldn't hurt.

Site wise I can't really see much as everything seems to route back to the home page. I'd say your tag line could use an edit - "Cheap college textbook rentals just got better" isn't really a call to action or very descriptive of what the service the site preforms.

Good luck!

Yay! I really love Euclid proof of The infinitude of primes. It is so short, simple & elegant that any starting learner could understand it easily.

http://primes.utm.edu/notes/proofs/infinite/euclids.html

I put it here:
Call the primes in our finite list p1, p2, ..., pr. Let P be any common multiple of these primes plus one (for example, P = p1p2...pr+1). Now P is either prime or it is not. If it is prime, then P is a prime that was not in our list. If P is not prime, then it is divisible by some prime, call it p. Notice p can not be any of p1, p2, ..., pr, otherwise p would divide 1, which is impossible. So this prime p is some prime that was not in our original list. Either way, the original list was incomplete.

But can we know that, if we're not only clueless about what an AI will be like, but even about what intelligence is? Why would AI ever want to "get out of the box"?

Will the AI get horny?

If it doesn't get horny, what else won't it get? It seems pretty clear that a majority of our behavior is a bunch rationalization for attempts at social recognition, response to sexual jealousy, self-image reinforcement, repression of complexes, etc. On top of that, most people I'd consider "intelligent" seem to me just well-schooled in social mannerisms, with a knack for parroting popular "intellectual ideas".

I'd imagine a true AI would have no reason to get out of the box... and destruction of civilization? world domination? I thought the point of power is to get laid, so if you can't get laid, what would the point of that be?
Edit: I've just thought of a wonderful addition to truecrypt involving the accelerometer... Anyone involved in the TrueCrypt Foundation here? Icanhazplz?

4 years ago when openbsd got a driver for the thinkpad accelerometers, i wrote a little utility that would watch the values and if it detected a sudden movement, it would run a script to lock the screen, remove ssh key passphrases from memory, etc.

i had an irrational fear of someone running into my office and stealing my laptop but i'd always forget it was running and would get up with the laptop and end up locking everything.

it would be useful in a server or desktop system since they should never move (and thus it could do something more drastic like a fast shutdown and power off) but since they never move they probably don't have accelerometers built in anyway.
If I had the money, I would. Yet another reason to do a startup.
Thanks for the feedback. We've thought about starting out at one university or even at a specific college at the university. We're racing to have it ready for Winter semester but are not sure if we'll make it.

As far as the links and the call to action goes, we threw that up while we relaunched the site. We're focusing a lot on the call to action once we really launch.

If I had to guess he has an old sony vaio series of laptops that had a problem with the fans not slowing down ever. There was a firmware fix for it a while ago. If there is not a problem with that then I would guess that the laptop has high cpu utilization warranting the fan speed increase. Seriously though you should get a linode account and let them handle the sound/power/bandwidth costs. 20$ a month and you can leave it on.
I feel kind of obligated to mention that you can also solve the same problem if the machine is sitting around fully unlocked (not idle and thus cluing the disk encryption in) with a cold-boot attack -- http://citp.princeton.edu/memory/ .

The short version: the contents of RAM are preserved pretty well during power loss if you cool the RAM chips, e.g. by dunking in liquid nitrogen or even just spraying with an inverted air duster, and the encryption key is stored in RAM so that the intended user can access the disk, so you can later recover the key from the frozen RAM.
Sorry I should have added more info. I have many cloud servers, this one is for a personal project that is running on Windows, and I have never worked with a hosted Windows server before and am not sure if I want to. So for now, I'm just running it from home.

EvilTrout - Just to verify your previous statements - I remember when I took networks in the 90s my professor told us UDP was the way to go if reliability wasn't a requirement and performance was important. (less overhead, and of course better latency, etc.) That was the how Everquest successfully implemented it. Many of the EQ players were using 9600 baud dial-up and were very happy with network performance when it first came out. Not to say they didn't have problems at the beginning. But they have long had an awesome hybrid (UDP/TCP) solution that's been tested for a decade.

It's interesting that we've hit a turning point with WoW. I can only imagine how much more pleasant it must be to code using TCP instead of a custom UDP protocol. It also may explain some of the odd network behavior that was "solved" circa 2002 in Everquest but occasionally happens in WoW today.

Right on. If you are going to focus on a single community I'd suggest branding the site (or at least a corner of the site) that way. When trying to build your first community I think it would earn more trust from people if they knew that this service was being focused at them.

I've been carrying my wallet in my front pocket for years for this exact reason.

(Not really related to the topic, I know.)

Seriously though, I had back pain for quite a while. My doctor asked if I did a lot of sitting. When I said yes, he told me to take things out of my pockets when I would be sitting for a while. This was kind of a pain, so I just started using only the front pockets.
Thanks for the feedback. That is definitely one of the pain points we are looking to relieve. Good to hear that it resonates.

Yeah the stock photo is probably a bit too market-y, will work on replacing with solid content.

You are able to add any songs you don't own to your shopping cart for purchase. The downloadable software not only allows you to upload and share you itunes playlist, but it also allows us to provide you with purchase protection so you don't buy music you already own. The software also syncs playlists from the website with itunes or windows media player.

I am definitely hoping that Facebook and Twitter turn into viral loops.

Thanks for your feedback. It is much appreciated.
Afaik, finding support for CS students is not hard in many schools. Many other departments recruit RAs from the CS dept to help with their research. e.g. I had a RA with Arid lands research program 3 out of 4 semesters during my Master's. Though this will probably vary from uni to uni and this info can be found by getting in touch with some Master students in the dept.
Also, I had a TA in my last semester. So, its a YMMV for RAs/TAs depending on the university.

I think I've come to accept that my gift cards will expire at some point. I'm not sure I'd be horrifically broken up if I went to use a card after a year, and it was no longer active. In fact, if the card worked, I'm not even sure I'd notice to appreciate the company's noble efforts.

Granted, a great user experience should be so seamless that the customer never even considers it, but I'm sure that there are some great brands out there that allow their gift cards to expire. I doubt their image has struggled enormously. Can anyone name examples or give stories?

I love the spirit of the article, though. Arbiters of the truth, indeed.
