I've started a new project while I learn C++ to post about what I've learnt, what problems I came across and how I went about them. It's my hope to help fellow beginners with the problems I face and to help them overcome them. I'm trying to explain things in layman's terms so that it's easier to understand, and I will be posting puzzles and exercises for people to work through. Hopefully, with enough interest, I'll invest in web hosting and provide a proper site where a community can develop of likeminded beginners.

Any feedback and suggestions are welcome!
That word: I don't think it means what you think it means.
Then they'll do what they did for books – introduce distortion. reCAPTCHA has already solved this problem.
If Google is using those pictures as captchas, it is probably because they could not write an algorithm to decipher them.

If, in the worst case, this results in spammers creating even better pattern recognition algorithms than the current cutting edge, it is certainly worth all the effort.
I have one. I can't imagine any modern, budget laptop performing worse than a chrome book. As a last resort, I tried it with my 6 year old son, and he said it was too slow. It now sits in a pile of books.
Your link says the loss includes "$510 million of stock-based compensation expense for restricted stock units issued to employees" - that's not marketing.
I loved that question.
I'm not saying that being annoyed at meeting == burnout. I'm saying that it is a contributing factor just like resentment over unequal compensation, etc.
Silicon Valley to Hollywood is a good analogy.

Something I would love to have is a debugger for an interpreted language which visualises the program's state as a graph, say, and you can wind time forward and back. Then, as you make changes to the code the visualisation updates according to what the program's state would have been at this point in the program had it been running the updated code. To me that would feel like magic.

User responses to the pictures are not checked for correctness. Every time you see a reCAPTCHA, you can just enter a garbage value for the word that is less distorted and the system will accept it.
Am I the only one who feels like the game demo was so awesome that it overshadowed some of the other parts of the presentation, parts that were just as interesting yet probably more feasible? I would kill to have just the algorithm evaluator part become reality.

I built almost the EXACT SAME APP at a startup weekend. Lots of people have this problem where they'll write something down and then totally forget about it. Our approach is slightly different but very similar.

Shameless promotion: http://thoughtback.com

We didn't really market it beyond the local press we got from Startup Weekend. We did launch the Mac app the first day of the Mac App Store though so that got us about 10,000 signups.

It might be construed as a partisan comment, but that is exactly how politics works. After working on a few campaigns (and leaving in disgust), a politician or party will gladly pocket an easy but visible decision like this in order to "steal eyes" away from other -- less positive -- changes or events.

RISUG is indeed a great contraceptive, but when talking about its benefits for HIV we should be incredibly careful.

RISUG isn't a cure-all. Transmission is still possible through microtears and directly through the skin of the glans penis and the meatus. And RISUG does nothing to prevent female->male transmission.

It's far too easy for "RISUG inactivates HIV in some components of semen" to transmute into "It's ok baby, I got a shot that protects me from HIV!"

You must be young. Vasectomies are a perfectly normal and routine operation in later life. I'd wager a large percentage (if not a majority) of age 50+ men in the US have them done. It hurts for a weekend, and then it's over, not a big deal. This sounds like a significant improvement over the current procedure.

Heh, I always get downmodded whenever I comment about stuff like this. The crazy thing is that at an 88% failure-to-reproduce rate, this is literally lower than the percentage of studies demonstrating efficacy in psychic phenomena, prayer, acupuncture, etc. I know it's an apples and oranges comparison, but still.
Honestly, this looks like automatically generated code.

Depending on what you mean by "young," I respectfully disagree. Highschool? Middleschool? College? All of the above? Speaking for myself and the people I know (early twenties, college-educated kids), condoms are pretty common place. A lot more common place, actually, than birth control. But then again, I don't have a large sample size that cuts across socio-economic backgrounds.
All hormonal contraceptives are not created equal.

Cancer and heart problems are side-effects of estrogen or combination (estrogen + progestin) hormonal contraceptives. Progestin-only contraceptives (which include Implanon, Jadelle, and Mirena) have never been shown to cause cancer or heart problems.

As always, don't look for medical advice from HN.

I'd invest it into my current company and apply to YC for my next idea, in the next round.

Can you see the headlines on TechCrunch already: "Five million dollar man to join YC", "Man who makes millions rain has a new idea, VCs interested", "Lucky Millionaire claims: 'I make my own luck', anyone buying?".

It's not a zero sum game you know. ;)
Unfortunately, as far as I know there is very little useful phenotypic data along with these genomes to work with. I would rather have fewer genome sequences with better phenotypic information. Even with just 35 genome sequences of "individual" yeast genomes I could do a lot more interesting analysis because they are well studied in turns of phenotypes.
An amazing nod to the tech / HN / startup community.
I meant it's a sort of semantic equivalent of Telephone, where the message stays the same but its meaning gets changed.

A smart programmer can B.S. his way through business. However you can't B.S. your way though programming and still make it work. The worst possible idea I could think of is for a non technical founder to try and "hire" someone unless it is a really simple app. Implimentation > Idea
I used to be of the opinion that the technical people did all the hard work and hence they should get the majority of the equity. However, once I tried to do everything myself I realised that the technical side was only one piece of the puzzle.

Business, design and marketing may not be as intellectual as programming but they are no less hard and often more important.

I really think that if two people are involved, the equity split should be 50/50 regardless of the skill set each one brings. If the equity is unbalanced, the level of effort each founder brings will be too.
Most IQ tests - at least ones I've seen - are highly trainable, both in general (you learn to think certain way) and in particular (you learn to solve specific type of test). So while tests aren't race-dependent and there's no reason to think they might be, they definitely can be culture-dependent and income (or, more precisely, education level and type) dependent. So while the test is an objective measure, it in an objective measure of test performance, which may not be strongly correlated with the actual work performance. Remember those "move the mount Fuji" interview questions which were so in fashion some years ago?

I'm not saying banning them completely the right answer here, but putting too much faith into these tests can be dangerous too.
I don't think anyone can realistically expect to find a google-scale diamond in the rough at every single YC batch. "Frighteningly Ambitious Startup Ideas" I suppose is about a process of collective unconscious iteration that would yield such a diamond every 5 or 10 years.

Agreed, but spread knowledge of this in Africa where HIV is a big problem, and isn't well understood or cared about (to western standards) and not only could it be a cheap and affordable birth control, but if it reduces the risk in transmission of HIV then its still coming up double.
What I don't quite understand about this piece is the motivation for saying that the biggest value-add would be to 'kindly inform the person that the correct term is 'co-founder'" (I am purposely trying to keep this comment symmetrical by leaving out "technical" here...). Why would it be valuable or even 'charitable' to do this? Them calling programmers 'programmers' or vice-versa has no negative effect for the named person- IN FACT it has a large positive one as it marks those people who don't have proper respect for their counterpart co-founder role. 'Kindly informing' the transgressor of such a misphrasing is like giving them the secret password without them having earned it themselves via a proper, self-driven cultivation of proper respect for their counterpart role.
You've got to have big ego to write, that Bret Victor's innovative ideas are not "entirely abstract art house visualization nonsense". BV's demos set the direction in which the whole field of working with ideas, including designers and programmers should be going. In 2012 programmers shouldn't have to be really good at running the code in their heads while writing it.
The ugliest, deeply-nested part is just a machine-generated classification tree (e.g., http://en.wikipedia.org/wiki/Decision_tree_learning).

Notice how all the leaf nodes (ends of if/then branches) do only one thing: set isDirty to 0 or 1.

And, all the if/then conditions are just thresholds of one variable against a constant threshold.

The later part seems to be exceptions to the above tree. I've never heard of this, but it seems like what they used:

As a developer, I agree that captchas can be a drag on users, and I think we should put serious thought into whether or not their UX-cost is justified. Personally, I try to avoid using them on sites I build.

That said, as a user, it's hard to hate ReCaptcha after hearing Luis von Ahn talk about and defend his invention: http://www.youtube.com/watch?v=-Ht4qiDRZE8

It's a clever way to digitize books (and now street signs) while keeping out spambots, and when I combine that knowledge with my affinity for Luis von Ahn as a person I find myself less annoyed every time I have to prove I'm not a robot.
Specifically, it looks like someone created a decision tree using Weka's J48graft class, then translated it automatically to Python code.
From a privacy standpoint, what effect does this have on us? I kind of cringed at the thought of my house number being spread around the Internet for strangers to solve.

Are my concerns unfounded?

2) If they are successful in one industry, they might be able to apply the model to many/all industries.
From the description of the project: "The tool was developed using models resultant from running the J48, J48 Graft, PART, and Ridor machine-learning algorithms on a dataset of approximately 100,000 malicious programs and 16,000 clean programs."

This is just machine-generated J48Graft code. Amusing, but not as terrible as it appears at first blush.

Was Apple not able to pave the way for a streamlined system to handle this?

If Apple could manage it then Google should be able to, at least if they tried properly.
Good point, that must be it. It seemed consistent with something I remember reading last year where they had made some implausibly small profit. For example, the article says:

Non-GAAP EPS was $0.05 for the fourth quarter of 2011 compared to $0.09 for the fourth quarter of 2010.

I think what this really proves is that I don't understand GAAP or SEC accounting and things look especially mysterious to me around the time of an IPO.

Thanks for pointing that out.

It should be noted that estrogen doesn't cause the cancer. The cancer exists and actually feeds on estrogen.

A woman's body is likely to find and destroy the defective cells before it's too late, but when you're taking hormones to overpower your body, you also have the risk of feeding the cancerous cells.
More business rational to head over to HTML. Interestingly enough their pricing model puts it directly in competition with engines like Unity and even the Unreal Engine.
> There was (and in many cases still is) a heavy cultural bias built into standardized IQ testing. Traditionally, most tests were developed and tested against middle-income, white children.

"It has been suggested that various aspects of the way tests are formulated and administered may put African Americans at a disadvantage. The language of testing is a standard form of English with which some Blacks may not be familiar; specific vocabulary items are often unfamiliar to Black children; the tests are often given by White examiners rather than by more familiar Black teachers; African Americans may not be motivated to work hard on tests that so clearly reflect White values; the time demands of some tests may be alien to Black culture. (Similar suggestions have been made in connection with the test performance of Hispanic Americans, e.g., Rodriguez, 1992.) Many of these suggestions are plausible, and such mechanisms may play a role in particular cases. Controlled studies have shown, however, that none of them contributes substantially to the Black/White differential under discussion here (Jensen, 1980; Reynolds & Brown, 1984; for a different view see Helms, 1992). Moreover, efforts to devise reliable and valid tests that would minimize disadvantages of this kind have been unsuccessful."

You'd be surprised. With automated posting tools, the cost of probing many different sites and posting massive amounts of spam (in an effort to raise search engine rankings) is very low indeed. I've run several small forums, and without fail, eventually they'd be overrun with spam and I'd have to either 1) install authentication or 2) install a captcha.

I agree that captchas are user-hostile. But, when weighed against the alternative - a forum or comments section so filled with spam and nonsense as to be unusable - captchas are by far the lesser of two evils.
I am. I should have been more specific, but at the time of posting the Nexus S rollout was volatile enough that the distinction didn't seem important.

Regardless, it took several months too long, for either model.
State of the Computer Book Market (part 1)
For RIM to come back, just having a new OS (BB 10) and shiny hardware is not going to be enough.

As an aside, Nokia, a company with similar brand recognition - albeit in a different market segment - is trying to claw back into the game is using Windows Phone 7 and Lumia 800, 900 series of phones. If I see this correctly, Nokia isn't betting on just the new hardware and Microsoft's OS (and financial muscle); they are also implicitly optimistic about Windows Marketplace and other content (XBox?) gradually becoming seamlessly available across it's product range. Content and services are the key; a decent piece of hardware and a decent OS should be agiven.

The reason I brought up this is that for RIM to make a comeback, they need to be able to offer something more than Apple is offering at the moment; that's the only way to entice users away from a platform they've invested in. In my opinion, the only company that can provide RIM with an edge in content and services is Amazon.

I wonder if RIM and Amazon can cut some sort of a deal. Amazon already makes a tablet that is fairly successful; the prospect of mobile phones with the Silk browser running on them, seems quite interesting.
The way I see it, contraceptive is for the person using it.

So if the guy doesn't want the girl to get pregnant, or wants to avoid STIs - he should use the appropriate protection.

If the girl doesn't want to get pregnant, or wants to avoid STIs - she should use the appropriate protection.

(Both people want to avoid pregnancy/disease? Then both should use protection!)

That way you don't need to worry about what the other person is doing - you manage your own expectations.

If you're in a stable long-term relationship and have talked about it, then sure, you can rely on one person, but otherwise each person should, imho, manage their own contraceptives.
Because life is long, and when man plans, God laughs.

You could divorce (or be widowed) and remarry. You could tragically lose your existing children. You could simply change your mind - it does happen.

Should this happen to you, a shot into the vas to reverse things would be far, far easier on you and more likely to succeed than a vasovasostomy or a vasoepididymostomy.
Cool article! I think a broader question raised is one I have thought about a lot: what is the optimum trade-off between narrow clarity of function/purpose and broad ambition/expansiveness/spread of features? On the one hand: we obviously admire and use things that are ambitious and full-featured (google, facebook, etc. etc. etc.) On the other hand though: HS points out that the narrowed "X for Y" model makes a better YC pitch... but more importantly, it might make a better consumer pitch. E.g. sometimes I wonder why I don't use wolfram alpha more often... and I think one of the answers is that I don't quite know what it does. It possibly covers TOO much area and I might- at a moment of quick snap judgement- pick the far more limited service with the easily comprehensible/memorable single feature claim... Thoughts?

I don't think I understand this question. No job you take (in the U.S.) is guaranteed to be there in a year's time. You might work for a month (being paid a month's salary) and poof the job's gone - company folded, political bullshit got you caught in the crossfire ... whatever.

You keep a fraction of your income in savings for just such an occasion. You add that month to your résumé and move on to the next job that might not last. This assumes you're not the reason you lost the job, of course.
