I thought java had switched to using a slightly more optimal lock xadd for AtomicInteger/etc updates? (see http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7023898) Doesn't address the main issue of memory synchronization between cores, but should make things a little better?
>At 3.5 million inserted documents, the exit velocity of standard MongoDB was 2.11 inserts per second...

That's terrifying - do people expect performance like this? Or was this crafted to be a pathological case? 100 element arrays don't seem too common, but that only makes this 300 million entries in e.g. a SQL table - I suspect my laptop running MySQL could outdo that kind of performance (but have no proof. I could be very wrong).
Contracting is more akin to mining for (high) pay. A better simile would be something like RubyMotion (http://rubymotion.com) by my friend Laurent Sansonetti. That's selling pickaxes (and excellent ones at that). Training for iOS developers would qualify as well.
I was finally able to play it, and one issue I noticed was that the sound becomes choppy when there are a lot of projectiles on the screen (which is, all the time :))
I don't understand why your defending this. Do you support this practice? 32 GB partitioned off for apparently no purpose?

Also, I've always hated the "you aren't the target audience" argument. Lenovo sells a device advertised as having 128GB SSD. But because its targeted for casuals its okay that less than half of that is available? Are they not worthy of getting what they thought they purchased?
"A meta-analysis of prospective epidemiologic studies showed that there is no significant evidence for concluding that dietary saturated fat is associated with an increased risk of [coronary heart disease] or [cardiovascular disease]." http://ajcn.nutrition.org/content/early/2010/01/13/ajcn.2009...

Disregarding your specific mention of saturated fat, grams of fat produce more calories than grams of sugar, so the Fage has 190 and the Dannon has 160. At that point (100+ yogurt cups to make a 1lb difference), it really comes down to the individual deciding/recognizing their body's own reaction to each macro-nutrients and fitting the right version in to their diet.
I took a similar course at the National University of Singapore called 'Competitive Programming'[1] taught by Dr Steven Halim. It probably has to be one of the most fun courses I took at uni. I didn't really learn much theory since most of the content is already covered in a standard algos course, which was one of the pre-req. But I think my programming and problem solving skills went up a notch. Our assignments were basically on solving problems from the UVA Online Judge[2]. We had two competitions for the mid-terms and finals. Each had an individual component and a team component that run on a custom grading server.

For 110 years, I suspect we'd be better off simply creating a larger lens array somewhere nearby in space. Might not be cheaper, but would probably be more valuable in the meantime.
I don't read the data like that.
What's missing in that data is how many solo founders there are compared to non-solo.

I think you are assuming that their are an equal number of solo-founder companies as multi-founder companies, but I don't believe that is true. I wouldn't be surprised at all to find that 80+% of companies that are looking for funding are multi-founder. If that is the case, then the odds of getting funded as a solo-founder are equal to the odds of a multi-founder company.

However, we also need to consider how we qualify those companies which are likely to get funding or ready. Many solo-founder companies are not ready, but by the time they are ready, will possibly have added a co-founder.

Either way, the advice I think should be just to keep doing what you're doing. If YOU think you need a co-founder to be active in the company, you get one, if not, you don't. Investment shouldn't come as a result of that decision, unless investors are thinking that you can't do it without a co-founder, and they might be right.
Why Linus Torvalds would rather code than make money
"Mineral water" means many things. Do you use it as a synonym for carbonated water? CO2+H20 forms carbonic acid, so carbonated water has a dilute acid in it.

Otherwise, I don't see how mineral water could affect your teeth. Was it especially hard water, or with high concentration of other chemicals?
And DragonFly's dntpd! It's time sync algorithms are actually pretty cool.
My point was, 5 years ago no one imagined a concept like Square would exist. Just because you can't imagine a nongovernmental organization that serves the same purpose as local health inspectors doesn't mean it's impossible to have such a thing.

On the contrary, quite a few similar organizations do exist, but only when a government monopoly doesn't kill competition in that space. For example, who in the 90s would have guessed that something like TrustE would exist. It's not that far fetched to imagine that if government wasn't policing restaurants a private organization could exist to provide such a service. Yelp doesn't do that because it's not their mission and no one is going to make that their mission since the government already monopolized that job.

I'm not saying we should have 0 government either, but if we're not willing to question the necessity of things as trivial as local government health inspectors then where do we draw the line?
I think maybe you are getting downvoted because you are mis-understanding the co-founder relationship. Steve Jobs didn't build the PC, but he knew how to get market it and get investors involved and run a business (or at least he was learning at the time, which gave Woz the opportunity to keep building and coding).

The company is nothing without a product, so in that case you are correct, but often the co-founder relationship isn't everybody building, it's sharing of all the responsibilities necessary to run a business.

Just to note, I'm a coder, so don't think I'm some MBA guy trying to justify my value.
What is also especially interesting is that a lot of the same ideas are also really important in writing HPC grade numerical code!

Thanks for the links. The [2]: article is interesting in a number of ways that I'm hesitant to get into here. I'm aware of Ornish's research on lifestyle, and think that support groups are a great idea.

But here's the rub: Say my employer gets rid of the candy and sponsers a support group at work for people who lack willpower. That's great! But what about the McDonald's and Burger King down the street? Should my employer lock the doors during work hours in order to control the willpower of its employees who might attempt to buy lunch at such places? What about at home? Should my employer attempt to control the shopping habits of its employees - and perhaps conduct impromptu spot checks of our homes to ensure that we aren't deviating from policy?

The point is, at the end of the day, the group can only police so much. Again, support groups are great, but the choice to make a change is with the individual. The alternative is removing free will. That's all I'm saying with my OP.

Just a random fact, for those that use Snort[1], this article brings up the same reason why stream processing in snort is single threaded. See their attempt to make it multi-threaded:

http://securitysauce.blogspot.com/2009/04/snort-30-beta-3-re...

Edit: to clarify, snort can run across multiple threads, but a single stream is handled by a single thread. When they tried to process the same data in multiple threads at once, cache synching killed performance.

Yeah I make real yogurt at home and I've had real yogurt in the middle east.

You really want to make the argument that these american programming offices have access to homemade yogurt? I really am skeptical this is an option when even fresh vegetables are not normally available.

It's like you're asking why don't they eat partridge, peacock or grouse meat in order to avoid the hormones in commercial chicken from the grocery store. Kind of an absurd argument. Why don't we restrict the discussion to what is actually going on rather than some unrealistic fantasies?
I must certainly do.
Saturated fat isn't bad for you.
Nice! Do you have a quick example you could share?
There is an exception though, which is building apps for some established brand who's business is not selling apps.

Even some fairly small companies now want their own 'app' in order to seem hip and modern. This could be anything from a spammy push notification thing to a crappy game that has been rebranded.

The purpose of these apps is not to have millions of downloads, but to have enough customers put it on their phones so that it helps them sell X more of Y where X is some number higher than what it cost to produce the app.
My comment history is more varied I think. My development environment runs a lot of stuff, so even if running two vm's at once were realistic, it wouldn't be.
Yeah, I think that's a bad thing. You don't?
Actually, they cracked a 250 year old code and found a secret society inside a secret society. (True. Read the article!)
Flot actually leaks quite a bit. We use flot at work and I had to hack the code to keep it from leaking. It doesn't leak as bad as NVD3, but it leaks. You will see it never surrenders the canvas element if you call shutdown on it if you check out memory snapshots.
Yes and yes. I don't like using the threat of violence to solve social problems, kind of like what parents teach children.
> Since then I've observed the trajectories of over 450 startups YC has funded.

... many of which may be a result of your inherit selection bias. Starting a company "that gets really big" is hardly a success criteria that an average first-time entrepreneur has in mind. You might not like how Ryan expressed it, but he's right - do not let the lack of a co-founder stop you from starting a company. It's a non-issue. If you have this option - great, if not - fine, and there are several upsides to it.
I feel bad for the couple featured in the article, but it looks like they didn't bootstrap their business very wisely. They sold their car, cashed in their 401K, and bought unnecessary hardware:

When the newest iPhone came out at the end of September,
the couple immediately bought two.

I've worked on iOS apps for 2 years, and still don't own an iPhone (an iPod touch suffices). Why did they have three Macbooks, an iMac, and a Mac mini for only two employees?

It's not wise for alcoholics to hang out in bars. It's not wise for someone struggling with marital fidelity to hang around strip clubs or brothels. It's not wise for people who know they have a tendency toward bad eating habits to surround themselves with free junk food.
It'll be interesting to see how the "app boom" turns out. The demand for apps right now reminds me of the demand for all of the shareware, etc programs of the late 90s, when personal computing was growing at a rate analogous to smart phone usage today. Utilities to speed up your internet and computer and the cute little animated tray programs, etc. (I had a soft spot for Tiny Elvis, who at random times would be awed at the size of a an icon on my desktop and then do a little jig). It was normal to pay for a web browser or video player.

I find myself only using apps that satisfy a core set of use-cases: favorite website consumption (HN reader, Reddit is Fun), media consumption, and social media. I play games much less than I thought I would have but I think it is the one subset of apps that will continue to see demand. The apps that list different types of knots...not so much.
I'd say - Look to what it takes for a local currency to succeed, and then consider the effect of crowd-funding and the Humble Bundle model. The former is what allows the system to sustain itself, and the latter is what allows an influx of resources from other systems.

just people they are so technical savvy doesn't mean they don't make mistakes. tests aren't perfect. you can't spend every day to write all corner cases. i don't consider that as ironic. i consider it as normal. users are so willing to help the software moving. that's the spirit of android software being open-source. we can find such small bug quickly and the engineers can fix this bug soon.
You seem to be unaware of how some people's willpower works. If I want to quit smoking, I don't carry around a pack and a lighter and just "use willpower" to avoid smoking. If I want to break my alcoholism, I don't continue going to all the same bars and just order water.
I suppose its a lesson for them in how real risk works. They traded in an opportunity with a high chance of making 200k for an opportunity with a very low chance of making 1mm+ and a very high chance of making much less than 200k. They ended up probably statistically somewhere in the realm of average which in reality should be of no surprise - its just unfortunate that it seems they didn't take many safeguards for when the most likely scenario occurred.

I think there is an unfortunate side to the way the tech media has turned into a machine at pumping out stories about all the big hits in that it gives a very skewed perspective of how rare true sustainable startup success is. That doesn't mean that it isn't worth pursuing but I think doing things like cashing in your 401k is incredibly foolish to be totally honest. I dont blame people for taking big risks being that most big success comes with big risks but make sure you are completely ok with what big risk truly means.
Unfortunately, there is no room for moderate Republicans in the party right now, and most such centrist "Republicans" are far too appalled by the intellectual dishonesty and social policies of the Republicans to consider such a move.

Giving in and becoming a "Republican" would just validate the party as it is.

I do have hope that the recent defeat will force an evolution, but I will wait and see.

What you say is true of a huge number of people I speak to, most I would say, and I yearn for a party that represents this viewpoint. They would sweep.

Unfortunately, I have to support the Democrats, who are too strongly tied in with entitlements and unions, in order to support a remotely reasonable set of policies.
I lose you at the part where you essentially claim that violence is free or unlimited. In reality, violence is very costly and risky. In this sort of analysis, I don't see why violence would be considered a separate variable, rather than simply one cost factor for both sides of the transaction, just like the cost of advertising, or paying employees.
"For it to end up with the right value at the end (M x N), two things need to be true." <-- the two things (immediate visibility and atomicity) are not strictly required. this is only required if all intermediate values are to be observed by the running threads. otherwise you can end up with the correct answer (M x N) without requiring threads to coordinate each write.

I draw the line at harming other people.

But since it's only hurting the person eating the junk food or using the heroin then who cares? It's their own decision. Why should you get to dictate how other people live their lives?

If you want to tell everybody it's a stupid idea and it's terrible, then go for it. I'll even agree with you. But at the end of the day, it's none of your business what other people decide to do.
Nobody takes security seriously until they've learned to distrust a computer they know intimately. It's a fact of life.
The IDE As a Bad Programming Language Enabler
Maybe I'm missing something, but I'm very surprised that the JVM would be implementing atomic increment with a loop that does "lock cmpxchg", retrying if it fails. The same can be accomplished much more easily (and safely, and probably with better performance) with "lock add".

For example, take this C program which uses the GCC atomic builtin __sync_add_and_fetch():

void f(int *x) { __sync_add_and_fetch(x, 1); }

This compiles into:

lock add DWORD PTR [rdi],0x1
ret

cmpxchg is also vulnerable to the ABA problem (http://en.wikipedia.org/wiki/ABA_problem), which the "lock add" approach is not.

"inc" is also an instruction best avoided these days, since it doesn't update all of the flags and can therefore cause an EFLAGS stall (http://stackoverflow.com/questions/12163610/why-inc-and-add-...)

I buy music for the sound quality, the ability to play back on any device type (xmms2 or my sansa player), and to support the artist.

Some artists share their songs on YouTube and being able to listen first makes it much easier to pull the trigger on buying the album. But I wouldn't listen to music on YouTube in preference to buying the files (or one of those shiny disks they had in the 2000s), even if the artist is making money through YouTube monetization.
>>The apps that list different types of knots...not so much.

If you look at AppStores there are apps with Types of Knots that has in access of Millions of downloads (Which I am sure had pretty good return).

Your analogy is wrong IMO. App boom is similar to Web Boom of Late 90's. Almost everyone says they only visit 1-50 websites a day but there are several 10K's of sites that are profitable.
The author of this gist is also one of the developers of http://appjs.org/. It looks like they may be related.

Me too, but they wouldn't. There really are more social conservatives than moderate libertarians, but if you're in the tech industry the latter is likely to be overrepresented in your social circles. I hope this will change in the next several years.

"google can disregard nofollow on a case by case basis"

This is somewhat correct. While Google won't disregard noindex/nofollow directives (or robots.txt Disallow) it can - and will - show "blocked" pages in SERP if
the quarry is specific enough or a the page is "strong"
(lots of inbound links/strong social signals and etc...)

However, it will not show in page info (hide description and title) and use alternatives sources of information to fill those out instead.

For example: it can use DMoZ info instead of the real one.
