Also by "things like these" I implicitly meant that I've heard many stories like that, including long discussions here on HN about invalid use of statistical methods. I just wanted to provide a single example situation that coincidentally happened just few minutes before I found this submission.
Hi,

I am the lead engineer at ArrayFire[1]. Is there anyway I can get in touch with you ?

This might not be appropriate advice for your current situation, but if you think you might face homelessness again, you might think about getting a van at some point. It will give you the minimum necessary to get through tough times. You'll still need to make enough for gas and some food, but you can live in a van for much less than rent. That, and a gym membership and you can get showers and work out. If you have a decent laptop then you can work in almost any coffee shop for maybe five dollars a day.

I'm not saying it a great option, but that it might be the best of a set of bad options.

Also, you might think about posting to Craigslist or similar, explain your situation and ask for some work. It certainly won't hurt.
"Now that product info is ubiquitous, the author says, the role of brands and traditional advertising is declining"

Declining but still very important. All else equal someone will make a purchase from a brand that they have used, know, or trust, over another brand which they have less or no experience with. I would also argue that even on a lesser feature set the existing brand has a clear edge. And there are other issues like wanting everything to look similar (say with kitchen appliances) or other tie ins.

Let's look at YC as a brand. My guess is that even if statistics were shown that another place was "better" for a startup (if better could be defined) the edge, because of the "brand", would go to YC. Now if YC is not "in your face anymore", say HN declines in popularity, that brand could easily suffer.
Some states do tax services (sometimes with some exemptions). Other states don't tax services, but do tax sales of digital goods, such as iTunes downloads, ebooks, or apps. There's no blanket "sales tax = physical goods" rule (it's not clear why there would be, especially in cases like ebooks vs. paper books).
Yep, its not like CL isn't a good first language. You'll just find few people recommending it as such, even more since scheme also exists.

Reading how hard it was for Boris to pass Landau's theoretical minimum makes me feel ashamed when I realize how much we students used to whine when a professor gave a slightly more difficult ("unfair") exam.

I wonder how test procedures differed in the Soviet Union from those in the US/Europe at that time.
in your case, the right answer is, "k, good luck with that"
Ask HN: What is a project I can complete in a night?
I have 8 hours to kill, and I can't work on any of my other code. I would like to be somewhat productive and build something. I know there is lots of 'weekend coding projects' but is there anything that you can attempt to build in a night?
Okay look at their balance sheet:

http://www.google.com/finance?fstype=ii&q=NASDAQ:AMZN

Their R&D was nearly $7 billion in 2013. Could you cut that in half while running Amazon exactly the same way (i.e. not improving it but not making it worse)? I think so, and that would improve profits by roughly 10 fold. Suddenly Amazon's earnings multiplier isn't 500, it's 50.

Furthermore there's another $12 billion in the selling/admin/general expenses line item. What's that? Could some of their building spree be contained within that item? Quite possibly. It's safe to say that it's coming from SOMEWHERE. I would be surprised if it cost them $300 per square foot between the building, the shelving, the conveyors, etc to build a new distribution center. At that kind of price a 1.2 million square foot building is a $360 million dollar expense. From what I gather they're building a couple of those every year. That adds up. What happens when they don't need to build new ones and can instead just operate their existing ones profitably?

Do you hear stories of people being worked to death at Target and Wal-mart? I hear that at Wal-mar they keep their employees just shy of full-time to deny them benefits, but I don't read stories about how they're asking to do inhuman amounts of work. But I do hear those stories about Amazon. Sounds to me like they probably have a more efficient workforce coupled with cheaper real-estate and very low "shrinkage" (stolen merchandise). If their supply chain is more efficient than Wal-mart or Target and they aren't selling stuff much cheaper (seems like the Amazon discount is about 10% at best these days) then it stands to reason they might be able to make more money.

I'm not saying that Amazon has crazy huge margins, but I do think that their margins are quite reasonable. They (Jeff Bezos really) just keep spending all the money they make to keep making the business better. Given how big retail is in the US I find it unlikely that they'll accidentally overbuild and find themselves in quite the predicament. It's not as though Amazon is building giant distribution centers on tiny islands where it makes absolutely zero sense. They're putting them near population centers, where people already buy stuff.

Wal-mart did $450 billion in revenue in 2013. Amazon only did $80 billion. Target also did about $80 billion. So Amazon is now as big as Target but not as big as Wal-mart. The reports of Amazon's impending demise seem a bit overblown to me.

I thought LuaJIT and other Lua runtimes are great for scripting and embedded environments, while Julia focused primarily on being a MATLAB replacement (i.e. desktop environments).

EDIT: Based on comments in the thread, seems both could do the same job but Torch7 has libraries that make running on GPUs easier vs. Julia.

I have no idea what makes you think a 10X developer can just "become" a 10X manager. This tendency of programmers to think they are automatically qualified, let alone interested, in being a manager is baffling to me. They are two mostly unrelated disciplines and in my experience, most programmers are not cut out to be managers.
How? High turnover + pair programming = paying significant amounts of money to upskill your staff who then leave.

It is no different to simply investing in a lot of employee training. Yes you keep the knowledge... But you are paying far more than if you just paid your staff enough to stay.

I think people are being harsh in the down-votes here.

I suspect most people (HN people) hold pretty strongly the belief that everything can be quantified. However, within reasonable limits and current stats and science, lots of things in practice cannot - yet at least.

A lot of advertising probably falls under this. To verify effectiveness we'd need, as the article notes, to control for so many other factors that it would often be too difficult.

So we often guess, or leverage past knowledge and apply it to what we hope are similar circumstances.

If you take the point to be that marketing is not a hard-science, than it's true. Some cases sure, but plenty not.
you completely missed the point of HealthKit and what Apple is touting it as and the capabilities your expecting it to pull out of thin air, it's primarily an app that lets you pull in data from multiple fitness devices with limited EHR integration capability as a bonus, what you are expecting is a whole different business
The article is written under the assumption - an assumption enshrined in American family law - that women are helpless and must be provided for by a man. Women lack agency and thus it is unreasonable to expect them to behave responsibly.

This is the law of the land throughout the Anglo-Saxon world (though thankfully not outside of it).

All is rather remarkable when one thinks about it. Women have the ability to jettison any child they do not want (either by killing it [!] or by post birth adoption), yet men of course are not afforded this right.

Tell HN: A hacker's guide to dealing with hair loss
I've taken Propecia (finasteride 5mg) for over 10 years. It works great, but for a student $60-$80 is a tough pill to swallow (pun intended). That works out to more than $700/yr.

A few years ago, I figured out a relatively easy hack to get the cost of the medicine down to less than $10/mo or ~0.30 a pill - which is way cheaper than even the shady online places that sell the stuff. Here's how you do it:

1. Tell your GP that you want to save money on Propecia (finasteride 1mg), and ask for a 90 day prescription of finasteride 5mg (usually goes by Proscar). Make sure your doc knows it's for alopecia, and that the 5mg tablets will be compounded into 1mg doses.

2. Fill the prescription at Walmart - total cost is $20. Do NOT pay with insurance, just PAY CASH. Insurance providers don't cover Propecia (reason: cosmetic), and if insurance pays for Proscar they may assume you have a different condition than alopecia.

3. Take the 90 5mg pills to a compounding pharmacy and have them compounded into 450 1mg capsules. This process costs about $130 for all 90 pills. Santa Clara Drug in San Jose does this well. The compounding pharmacy will need to call your doctor to verify that the intended prescription is finasteride 1mg. Once compounded, you'll receive a 450 day supply of finasteride 1mg.

Total cost is around $150, which works out to be $0.33 a pill, or $10/month.

Disclaimer: I am not a doctor, and this is not medical advice. Just a money saving hack that has helped me and some of my friends save money and keep our hair.

Another important dimension when evaluating these regexes is performance. The Gruber v2 regex has exponential (?) behavior on certain pathological inputs (at least in the python re module).

There are some examples of these pathological inputs at

That isn't unique to functional programming. I've seen my fair share of Java and C# code bases that could best be describe as baroque monstrosities. It's like the authors read Design Patterns and then decided they absolutely had to use every single pattern at least once. The clean code book is also somewhat to blame here as people who go full retard on that tend to write stupidly complicated class hierarchies just so they can never have more than 1 line of code in any given method (effectively turning most classes into proxy wrappers for other classes providing some default values).
What's wrong with IP-address URLs? If they are invalid because it says so in some RFC, this is still not the ultimate regex. If you redirect a browser to http://192.168.1.1 it works perfectly fine.

And why must the root period behind the domain be omitted from URLs? Not only does it work in a browser (and people end sentences with periods), the domain should actually end in a period all the time but it's usually omitted for ease of use. Only some DNS applications still require domains to end with root dots.
I have a co-worker that came out of school with an economics degree. In a couple of years he went from having no programming experience to cranking out pretty impressive apps with elasticsearch/django. (*I should clarify.. He started making apps right away. It took him a few years to make them what I'd consider professional quality).

I've been programming for about 20 year so really don't think I realize how difficult it is to pick things up.

Aw, too bad this wasn't posted in the HN thread because I would like the opportunity to vote it down. Calling someone a wimp because they have suicidal thoughts isn't helpful.
I agree. Apple did refer to major healthcare partners but my impression was that this was just to enable users to share fitness and personal monitoring data with their healthcare providers (which the healthcare provider could then add to the EHR). I saw no suggestion that Apple were aiming to attack the professional/enterprise EHR market.

I don't know if there could be a progressive expansion of capability and then an attack on the EHR market but Apple hasn't signalled that and it isn't currently intended for that.
Wait a minute.

Yes, if the allegations are true, it's worse than Nixon's actions, because Lerner and her acolytes went a bit further than endeavors: "He has, acting personally and through his subordinated and agents, endeavored to obtain from the Internal Revenue Service, in violation of the constitutional rights of citizens, confidential information contained in income tax returns for purposes not authorized by law, and to cause, in violation of the constitutional rights of citizens, income tax audits or other income tax investigation to be initiated or conducted in a discriminatory manner."

I don't know what the protocol is, but she transitioned and was named Danielle Bunten Berry. She died in 1998.

I guess since the article considers a time when she used her male name, I believe most trans people consider their real gender to have been set at birth and would generally prefer to be referred to by their chosen name. Since she's deceased, I prefer her chosen name.

Excerpt:

There is a frustrating absence of weight to their characterization. Like every woman in this universe, they stand wide-hipped and wasp-waisted. Their faces are as rounded as their mammaries, framed with either a halo of leaves or what resembles real, fibrous hair cast in plaster. And where their Y-chromosomal counterparts might bear chunks of inscribed facial granite, the female Granoks are restricted to woefully mundane-looking earrings. Earrings. Why the Holy Carpfish of Good Taste would they want to wear ornamentation of such a manner? Big, bold jewelry clipped to the ears seem a ludicrous decoration on a race built on combat, don't they? What if they get ripped out? What if they catch a glint of dying firelight and divulge the Granok's location to hypothetical quarry? Why can't I make my bold, boulder-y lady not pretty?!

The record format is the same one that is used for DJBDNS, which by default does not support IPv6 addresses. There is a patch that adds IPv6 support, records start with 6 for IPv6 records.

If you want to create a record named:

6www.whatever.com

You would put that into the file as:

66www.whatever.com

Only the first character is used in the DJBDNS record format to specify what the rest of record type is.

Again, driving a company may can't be easy but it can't be a torture too.

Not all hackathons are nearly as bad as this mentions. I've found that CodeDay (http://CodeDay.org) as well as the hackathons part of Major League Hacks (http://mlh.io) have adhered to most of what the ideal hackathon constitutes as per this article.
I'm not an expert in LuaJIT, but it sounds unlikely that the performance characteristics of torch7 are due to the efficiency of Lua bytecode. The speed with which you can train NNs will be dominated by the performance of the linear algebra libraries which are utilised by the numerical optimisation algorithms (SGD, L-BFGS and the like). Almost everyone ends up using some variant of the BLAS libraries for this.
Agreed that it can be difficult to save right out of college. Due to my relatively low entry-level salary, as well as college loans and living expenses, I didn't start really saving/investing until I'd been out for ~4 years.

The problem is, though, starting saving/investing even just a couple years sooner can turn into much higher returns down the road, so it's a good idea to start that trend as early as possible. If you can find investments with a higher yield than your loan interest rate, it can make sense to pay the minimum on your loans and carry the debt for a while.

Nowadays I do save more than 50% of my income, but I also have no dependents or debt.

For me, it's not that these taxes, in particular, are ridiculous, but that the tax code is so freaking complicated, that I sometimes need a CPA to double-check my records (AMT, odd-ball deductions, etc). And this is for my personal income taxes - it's even worse for business owners.
And keep in mind, you'll want to be giving your employees a pay raise as well. They'll know what the clients are paying. Not a 1-to-1 increase, but maybe 30%. Make sure they realize you value their work.

Agreed, and also I suspect (or maybe this is just a silly hope) that the best developers in a company can often make more than their manager, even if their manager is great.

Now, moving up to director or VP level or higher (assuming you have the aptitude and desire), is a different story.

Answering a survey by pretending to be someone else is clearly unacceptable and fraud by the student if they encouraged others to do it. I’m pretty sure that would lead to that student failing the class or worse if it were discovered where I study. The same is (even more) true for faking data. That’s a disgusting violation of all scientific standards. For any somewhat larger project that might yield actual useful data our teachers are usually also involved to a degree where they would know if something like that is going on to a massive degree.

It is also standard practice to disguise these kinds of filter questions in surveys and to leave possible respondents in the dark about the ultimate purpose of the survey (insofar as that is possible and it isn’t ethically necessary to be transparent about certain aspects). That way respondents outside the filter criteria hopefully couldn’t participate even if they wanted to fake their way in. The way I do it, no one besides my advisor and a limited pool of pre-testers (who I make sure to tell not to participate in the main survey – and I also try to keep the link to the survey away from them) knows what the survey is about and what are the filter criteria.

That’s students. Most of them won’t go on to do any actual worthwhile research that will ever be cited by anyone. I would hope that the standards are even higher for research that’s published in journals.

Social research is tough even if everyone behaves ethically. No doubt about that. But I have never encountered any culture of fraudulent behaviour outside of lazy students who will never publish anything anyone cares for.
There's also the pervasive attitude that people will stay because of the projects, culture, people, etc., and don't care so much about the money. That can be true to a certain extent[1], but I think the people who make salary-bump decisions think way too much of it.

[1] I suspect this is actually very true when an employee starts fresh at a new company, but, over time, the money (or lack of it) becomes more and more important.
Compilers are well-suited for functional programming, which is why language designers seem to love it. Looping is almost never natural in a compiler. It's always recursion through trees of some sort.

I guess functional programming maps nicely to problems that do not simulate something through time and which primary work is not IO.
