Thank you for this. I agree, ultimately.

But for now, I'm looking to build a roster of engineers who we'll be able to reach out to as we get into the beta testing stage. We're a couple months away from that, but we're prototyping and building, so we want to be strategic and ready (rather than waiting until the last minute).

A stackoverflow for researchers in biotech/medicine/biology would be extremely useful. In biological research, if someone wants to do an experiment that they are not experienced in, they can review peer-reviewed published materials, but many important details are left out. There are many matters of technique, and many decisions about which protocol/solution/tool/etc to use for the experiment that may not be easily accessible via published sources. In these situations, a well-connected biological researcher would ask a colleague who is experienced in the particular experiment. This is not always so easy though, and much time can be wasted re-discovering a simple issue that many others already knew.

In software, this kind of knowledge has been available online for years. In other technology fields, this is not the case. A easy-to-use, well designed forum like stackoverflow for biology research could be a real boon for the field. The only problem I see is getting people to use it.
I've started with searching for a martial art fitting for me 2,5 years ago. I hadn't been training for a quite some time and I really needed to do something about it. I had practiced Judo during my child and early teen years and practiced Tae Kwon Do during college.

I quit both because, in my personal opinion they are too focused on doing one thing fairly well while more or less ignoring other aspects of fighting. For example: I found it very annoying that Judo did not allow any punches or kicks. While Tae Kwon Do didn't allow throws or ground fighting.
Basically I was looking for a different look at fighting, be it kicking, punching, locks, throws or fighting with weapons. In my view everything should be possible depending on the context. At that time I found two possible matches (in my neighborhood) for what I was looking for in a martial art: Takeda Ryu and Krav Maga. After having followed three lessons of Takeda Ryu I didn't bother of looking at Krav Maga anymore since Takeda Ryu and the people training at the dojo matched what I was looking for.

So now I have been training Takeda Ryu Kobilza Ha for 2,5 years. I'm still just a beginner and need to learn a lot, but I enjoy training very much and that's what I consider to be the most important. Whatever martial art you like to start make sure you enjoy it and feel safe in the dojo.

I have the impression that it does have an effect on me outside the dojo, although I find it hard to describe what the effect exactly is.

Currently I'm practicing five budo disciplines in Takeda Ryu Kobilza Ha:

- Aikido (throws, locks )
- Iaido (swiftly drawing the sword and cutting correctly)
- Jodo (fighting with a stick)
- Jukempo (kicking, punching combined with throws and locks)
- Kendo (fighting with a drawn sword)

If you would like to know more about Takeda Ryu, have a look at http://istb.info/index.php/home.html or look at some footage of demonstrations: http://www.youtube.com/watch?v=INx_CSA_I78 and our main event in Vienna Austria: http://www.youtube.com/watch?v=4sxtTNjKSsk&;

ps: This is my own very personal and limited look at martial arts and I do not want to disrespect any Judo, Tae Kwon Do, Krav Maga or any other martial art practitioners.
If you don't like the taste of that (decaf tastes bad to me) or just want more control over your intake, caffeine pills aren't a terrible way to go as a temporary solution.

Figure out how much caffeine you usually drink, and take that much with no liquid caffeine for a couple of days and make sure you're ok with that. Then slowly lower your dose until skipping only leaves you with a mild headache or none at all.
I like the disdain when he derides Americans for not driving electric cars. He's right ... America has some serious systemic failures, despite being founded on great ideas.

No wonder he's a billionaire. Also, finding that fool-proof un-mechanized goldmine helped I'm sure... I learned that lesson at a poker table... don't play with experts, play with rich scrubs.

No, the worst merge lane is the Treasure Island ramp onto the SF-bound lane of the Bay Bridge is the worst ever. You have approximately 5 feet to get from a stop at a stop sign to highway speeds.
It doesn't work this way, at least not for everyone (genetics), exactly because of the muscle loss that occurs when you decrease caloric intake. Of course you can prevent it in some ways, but then it is no longer just "subtracting 250 kCal". Nutrition is complex, so I would not give advice this simplified about it, as it can get you in trouble, just as putting 15lbs weight in a month. Maybe you have good genetics, or already follow a well-balanced diet, but people who follow your advice not necessarily so, they should thus pay more attention to this aspect of "training". I learned this lesson the hard way, so I wish the advice in "Starting Strength" would be more balanced in this respect.
Am I the only one that thinks people should stop worrying about startup hubs and focus more on making cool stuff?
I don't want to be mean or rude, but those icons aren't fresh. I'd say a good hundred new sets of icons are developed every week. They all, from my viewing experience, look almost exactly like those ones in the link you posted.

New icon sets can be very interesting and entertaining. These, however, are just icons- some almost identical to normal ones.

Also looking for payment processors outside US.

About Paypal, AFAIK they can transfer funds to your credit card (not bank account) for about $2 per transfer. You have to authenticate the card before. It involves them making a small transaction from which you take a confirmation code (from the bank statements). Takes about 2-3 days.
Doing a set with a large number of reps is neither easy nor useless.

It's not easy because you're supposed to do it until failure.

And if you're aiming at improving your muscular endurance, then lots of reps with a light weight are more useful than low reps with a heavier weight. There are several studies that show this. Example:

http://www.springerlink.com/content/t96qmxyaa7x7le0c/

Subjects were divided into four groups: a low repetition group (Low Rep, n=9) performing 3–5 repetitions maximum (RM) for four sets of each exercise with 3 min rest between sets and exercises, an intermediate repetition group (Int Rep, n=11) performing 9–11 RM for three sets with 2 min rest, a high repetition group (High Rep, n=7) performing 20–28 RM for two sets with 1 min rest, and a non-exercising control group (Con, n=5). (...) Maximal strength improved significantly more for the Low Rep group compared to the other training groups, and the maximal number of repetitions at 60% 1RM improved the most for the High Rep group.
Cool stuff always rules. The point is that timely, physical interaction between talented hackers and the "heroes" that inspire them will lead to more cool stuff being made even faster and more efficiently than ever before.

Thoughts?
Yeah. I believe everything I read even if I see obvious reasons why something is false.

Hmm, not sure this is a great story of engineering-can-make-you-rich or anything of that sort. Officially he "got his start in gold", but as the article also notes, he's the son of one of Brazil's prominent industrialists, who also happens to be a high-level government minister (nice combination). He's making a fortune in being an industrialist. One suspects he may not be an entirely self-made man...
In both cases, it's idiotic to throw away all the non-copyrighted parts of the work. It can't use the IP? Fine, throw out the IP, and use whatever's left over to make something new. GraalOnline did this with the Zelda IP, for example. Any author who got their start writing fan-fiction knows the reality of throwing out all the "canon" characters and setting and realizing you still have a story. There's just no sense in letting it all go to waste.
Call me a cynic, but I don't necessarily believe that Patzer's comments about why he sold to Intuit reflect his true feelings. After someone has just given you $170 million, the least you can do is say a lot of nice things about the deal, what great synergy there is between the two companies, etc. That's just how business is done.
I've commented on this here: http://blog.boxedice.com/2010/02/28/notes-from-a-production-...

Essentially this decision was due to the disk space requirements because of the way MongoDB allocates files for each DB.

No, it's the other way around. See my other comment and this:

Physical education students were matched into three groups; G90 (n = 9) trained with a load of 90%, G35 (n = 11) with 35%, and G15 (n  = 10) with 15% of 1RM (1 repetition maximum). Training consisted of three to five sets, performed three times a week for 9 weeks. Each set consisted of two, seven and ten repetitions in G90, G35 and G15, respectively. Training was performed with the nondominant arm, and the dominant arm served as control. The 1RM increased 15.2 (SD 4.5)% (P < 0.001) in G90, 10.1 (SD 5.9)% (P < 0.001) in G35 and 6.6 (SD 7.9)% (P < 0.05) in G15.

This bit was surprising to me:

In the untrained arm, 1RM also increased for G90 and G15. In contrast to G90, G15 showed a similar increase in 1RM in both arms.

Lifting weights adds too much "heavy" muscle and not enough "lean" muscle which I think technically is known as twitch muscle. I have tried both lifting heavy weights and just simple exercises combined with flexibility training that just involve using my own body as a source of resistance and I can tell you without a doubt that I feel way better when I have more twitch/lean type of muscles.
From my self-interested perspective the coolest part about the modern economy is that small businesses can participate in it as much as the big guys. Totally automated fulfillment? Check. Scalable online advertising? Check. User behavior tracking? Check. A/B testing? Check. Micro-multinational 14 time zones away from freelancers and customers? Check and check.

Heck, you can do all of the above in your spare time.
I disagree. The only thing gymnasts do is use their own bodyweight and as far as athletes go in terms of endurance and pound for pound muscle strength they can not be beat.
Does your startup pass The Sleep Test?
of course they would benefit more from more intense, comprehensive exercise. the point is that you can get in excellent shape with 1/10th of the commitment and effort that such a comprehensive program demands. constantly worrying over your next major gains is what makes the fitness habit so hard to maintain.

I've recently started Bouldering (http://en.wikipedia.org/wiki/Bouldering, "rock climbing undertaken without a rope and normally limited to very short climbs over a crash pad") in a Uni bouldering wall and am finding it a good way to increase muscle strength, whilst also enjoying the strategy aspect of deciding how to complete a particular route (which to me is more appealing than the repetitiveness of lifting weights).
Almost every successful(and even some which are not so successful) forum has a number of people who are addicted to that particular site.

In fact, I would wager that a number of us here on HN are engaging in highly addictive behaviour.

For those of you whose businesses should pass the Sleep Test (as in, have no permanent impediment like requiring sales presentations for $75k authorizations in B2B) but don't, I really can't recommend SEO enough. It is the gift that keeps on giving -- today, tomorrow, and until the end of time -- and it works whether you're asleep, at a day job, on a date, etc. Similarly, display advertising, search advertising, free trials, and automated fulfillment. (When I found you could send someone a CD with a HTTP POST I nearly had kittens.)
Unless your business earns revenue while you are sleeping, it won’t scale.

I find this statement oversimplified. I works for some models like basecamp, but some social services's business model can be simplified to "register for free and WE will pay you $100(ok, maybe not in cash but in value that they spend on average user/ or value that user gets of using them)". However as we can see some of these services growing really fast and probably can be huge success in future, just by monetizing their huge audience.

So i guess initial statement is mostly address bootstrapped startups, not taking VC/angel into consideration. I'd modify it to smthg like:

Unless your business earns revenue or traction while you are sleeping, it won’t scale.

Gymnasts are not at all as efficient about building muscle mass as body builders are. Gymnasts achieve great physical results in time, but nowhere near as efficiently as body builders do.

This should not come as a surprise to anyone — for gymnasts, building muscle is a means to an end, and they don't want to build any extra muscle as that just weighs them down. For body builders, building muscle mass is everything.
You can see real world examples like slot-machines.
I can only speak for the Chinese Martial Art I have trained and been exposed to - Wing Chun and Choy Li Futt. It is now a way of life for me. Primarily, I am a Wing Chun practitioner.

If you are using the Agile methodology, Wing Chun would be good. It emphasizes
1) adapting to change - This is especially true in the second form "Chum Kil" which transition from one position to another
2) least wastage - punch is a straight line to the target
3) cooperation to achieve a single target - a punch in Wing Chun is the utilization of the powers of your leg, hips, torso, shoulder, elbow transferred to the fist
4) getting immediate feedback - the chi sao (sticking hands) exercise trains you to be sensitive and look for places to enter
5) respect of difference of opinions - a tan sao can be used as to defend or attack depending on the person

If your SDLC is a waterfall method, try Choy Li Futt. Things I learned from this are
1) Commitment to a set of combination early - I have combos in Choy Li Futt which I carry through all the way, regardless of what the opponent does. The decision of what to do is made after assessing the situation (aka requirements gathering) and before the first strike

2) Using a different approach to a problem - My favorite strikes from this style is the spinning elbow and using the forearm as a striking weapon

The primary difference to me is that Choy Li Futt is a brute force solution to a problem and Wing Chun depends more on an algorithm to resolve the problem

Good luck!
I'd given up on QS and gone to google search box (or whatever it was called) - I happily am back on QS with this stealth release - much faster and don't remember the last time it crashed
DTerm is awesome, and since it went free there is no reason not to try it out even if you're a Quicksilver/LaunchBar user – you probably will find it serves you better in many scenarios.

And here's a nice tidbit – TextMate comes with `mate`, a proxy utility you can call with DTerm like so: `mate ./new_file_here`. But XCode doesn't, and won't create a file for you if one doesn't exist. So for XCode I have an function/proxy in my `~/.profile`:

function edit { touch "$1"; open -a Xcode "$1"; }

Bash can be very usefully augmented, for instance you can have a git repo status in your prompt, like so:

function wgit_dirty {
git diff --quiet HEAD &>/dev/null
[[ $? == 1 ]] && echo "◆"
}
function wgit_branch {
REF=$(git symbolic-ref HEAD 2> /dev/null) || return
echo :${REF#refs/heads/}$(wgit_dirty)
}
export PS1='\u \W$(wgit_branch)\$ '
No offense, but I think your opinion shows why most martial arts are in a state of disgrace right now. Martial arts are very different from one another.

True martial arts are supposed to give you three things:
- Ability for self defense
- Good health (not only physical health)
- Some sense of inner peace, zen, or whatever you may want to call it.

One of the many problems of the current state of things is that most societies are culturally oriented to consume things, the more the better (no offense, but the Americans excel at this). So most people wouldn't want to learn a martial art and start very slowly, nor they would spend 6 months learning the basics. They think that the more you learn, the better.

In martial arts, you learn very little and practice alot. In the past, students would spend 6 months just doing simple movements, one of the reasons was that if you don't get the basics wrong you would not go far.
I agree with you that today most people practice martial arts and don't have a clue of how to defend themselves, but in the past if a martial arts master would not know how to fight he would simply end up dead or severely hurt.
Nowadays, people want to be able to fight after 2 classes and want to be black belts or masters after one or two years.

A good example of this kind if practice is Muay Thai fighers. They do not show that many techniques, yet they are devastating because they dedicate and practice alot.
Another good example of fighting with strategy is BJJ. You see smaller guys with much less strength taking on bigger guys by employing smart strategy.

Either way, there's much more about martial arts than physical strength.
My advice is that you first define your aims. What do you want? Be a good fighter? Be in a good shape? Dedicate some time, or just a few hours on the weekend?

Based on your objectives, you will be able to choose wisely.

I love lifting and exercising, but I don't get at all how you're supposed to listen to audio-books or think through problems (consciously anyway; that wasn't made explicit) while you're giving it proper effort. I've always found that it clears the mind like nothing else, and often found that you have a better perspective on an issue afterwards, but it's the last thing on your mind when you're under the bar or gasping through a set of burpees (as another poster recommended).

Also, since people are recommending their personal favourites, I think you can do a lot worse than 5/3/1:

He sells (very cheaply) the program, but it's actually almost all in that interview. One thing not included is his own method for estimating your 1RM, which differs a bit from the article's: weight + weight * reps / 30. It has been a pretty useful approximation in my experience.
This article may create a wrong attitude towards customers and business imo. I believe it is indispensable to go out and talk and listen to people instead relying only on online-tools (by the way, that's what 37signals always have done, too). A company that is happy to pass the sleep-test, is very likely to start drifting off...
