Most impressive about LMDB to me is the zero-copy model for readers, with is no extra memcpy needed, maybe that is something obvious for database gurus but it is pretty clever trick I think.

How so? It's extremely short range, the only thing that can read it is the terminal you were about to give your card to anyway. It's not broadcasting while in your pocket, so nobody's going to read your card by bumping into you.
Either they updated the table since you posted, or you're misreading it. MySQL Large is $0.32/hr, PG Large is $0.336/hr, Oracle is $0.565/hr.

Yes, directories are walked continuously, with 250ms between each scan. So far this has worked pretty well (maybe on slower systems it should be slowed down). Over time I hope we'll get performance tweaked to an optimum.
This isn't true. Midwifery is a serious discipline and you must be licensed in the US. Also, they even have Doctors of Nurse Practice (DNP) of Midwifery at the respected Baylor [1] and other schools. I would recommend watching "The Business of Being Born" (it is on Netflix) - it is very enlightening about the safety and discipline of midwifery, and why hospital births are unnatural and in some ways incredibly unsafe.

Is this really a problem? Too many credit cards make your wallet uncomfortably large? Let's get back to solving problems that matter. I can't believe we have three companies on the front page today reducing the number of credit cards in your wallet.
Yeah, I know, but I don't have those stats available. Hence why I said it's in the ballpark.

What you see as waste, I see as valuable experience. In school, did you just read books and take tests? Or did you spend a lot of time solving problems that had already been solved, deriving equations you could have looked up, writing programs you could have downloaded...?

People learn by doing. You don't sit down and design the Next Big Language on your first try. You invent a lot of shitty, unoriginal little languages while simultaneously studying what's out there, and maybe eventually you get to the cutting edge where you can create something novel and better.

Android's market share maybe 80% but it is about 50/50 in terms of web usage.

I came to USA 4 years ago and already accumulated probably 15-20 cards. Few of these are store-credit-cards (Kohls and Target) but others are just regular ones.

Reason is simple - more credit cards - better credit score in the long run (it ruins your credit score in the very beginning tho)

I am using 3-4 daily depending on current rewards and perks and never carry balance (and as a result, never pay interest.) Like I put electronics on my AMEX simply because these purchases are auto-protected from accidents for 90 days. I put gas purchases on card having 5% cash back on gas stations, etc.

As additional bonus - I put not used cards into glovebox of each of my car and in case I forget/loose my wallet, I still have mean of payment with me.

It's pretty significant, yes. Eliminating multiple copies of everything got us a 4:1 reduction in memory footprint in OpenLDAP slapd (compared to our BerkeleyDB-based backend). This is another reason we don't spend too much time worrying about data compression and I/O bound workloads - when you've essentially expanded your available space by a factor of 4, you get the same benefits of compression, without wasting any of the memory or CPU time. And when you can fit a 4x larger working set into your space, you find that you need a lot less actual I/Os.
The University of Washington educates midwives alongside do tors and nurses: http://nursing.uw.edu/node/371

My wife's cousin is going through the program right now and will graduate with the equivalent of an MD. She's doing residency at a large hospital in Seattle and did clinical at another in Boise. When she graduates she'll be working adjunct at either another hospital up here, or through Stanford. I'm no medical expert, but I trust her experience and expertise. I'm not sure where you're information is coming from, but I think you may be misinformed.

Wells Fargo definitely has chip cards. They shipped me a chip version of my WF credit card out of the blue a while ago.
Not only are they serious medical professionals now, but they have been for a while. Watch the British TV show Call the Midwife. Even back in the 50s midwives were well-trained specialized nurses who dealt with serious medical issues on a regular basis.

I think you're thinking of midwives from a few hundred (or more) years ago, before the fields of medicine and nursing existed as they do today.
Yeah, I just worry about how men will fare in an equal society where mens inherent inferiority isn't (more than) made up for by the patriarchy.

Woah, interesting stuff. thanks
They totally forgot Bitcoin.
1) get two wallaby cards, one for business one for personal.

2) put your wallaby card into your coin.

3) carry wallaby and one business card

Today just got too meta. Now my brain hurts.
True. But it would work with all of your personal cards, which is the main proliferation problem.

You could use them together. Get a Wallaby as your "one" smart personal card, and if you feel like springing $100 to go from 2 cards down to 1, you've got Coin.

Personally I'd be a tad worried about handing my Coin to a server to charge a big business meal. What if they accidentally tap the button and switch to my personal card when they're holding it?
Yes, it's great to speculate on these things, as long as we rigorously discourage people from speculating that men are better than women in any dimension. We can have an academic discussion on the differences between men and women while avoiding sexism.

Your first point is spot-on. Home births are bound to be statistically more successful because they are (usually) only planned for low-risk pregnancies.

However, the increased death rate in the Oregon study is

a) localized to that state, and
b) attributed to an overabundance of uncertified midwives:

> But out-of-hospital births are not as safe as births in hospitals in Oregon, where many of them are attended by birth attendants who have not completed an educational curriculum designed to provide all the knowledge, skills and judgment needed by midwives who practice in any setting.

In other words, there are a lot of "birth attendants" practicing midwifery in Oregon who aren't necessarily CNMs (certified nurse-midwives) or CMs (certified midwives) -- which is perhaps closer to the barber acting as surgeon analogy.

EDIT: Here's a rebuttal to the Wax study: http://www.midwiferytoday.com/articles/ajog_response.asp

Really cool! In addition to the comments others are making, I would recommend making the intensity of the base blue and red colors match. The democrats look more intense than the republicans just because of the color choice when given how interlocked they are, I assume the average blues are probably about the same as the average red. (Also a legend would help.)

Awesome work!
So what happens if you hand your card to a waiter/cashier and they accidentally tap the button while gripping it? "Card roulette"?
> ...racking up debt

This is FUD. While there is arguably opportunity cost involved, it is not at all difficult to avoid "racking up debt" in grad school, at least if you're at the PhD level and in a STEM field. It is standard in such programs to get tuition waived (so, no cost) and to receive stipends for assistantship or fellowship (so, you get paid).

To get into specifics: I got my PhD in CS from Brown ten years ago, and my stipend was around $20K (I think about $22 or $23K my final year). During my time there the students clamoured for, and received, a healthcare benefit (free for the student, and they could pay extra if they had spouse and/or dependents). Because I was lucky enough to be debt-free going in, I actually finished grad school with about $15K in savings, but even my friends who had debt from ugrad were not accruing additional debt (and at the time were able to defer payment interest-free, although I gather that's no longer true). I was not exactly living the high life but was able to afford a decent apartment, ate out fairly regularly, and kept myself supplied with geeky tools and toys (laptop, wifi, etc).

So no, "racking up debt" is not a worry here.

As far as I know, neither of those things are true.

Many merchants I swipe my own card and they never see it. A waitress may question it, but I have no reason to believe they won't accept it if it is validated by their card reader.

The website says the battery should last two years.
Well, sort of. You could always carry this, and a Visa, so you're down from 4 cards to two.
I don't think there is a way to fix the https Vimeo issue. It's been a problem on a couple of the sites I've worked on for years and Vimeo acknowledges the problem but refuses to fix it.

> there is no physical imprint / swipe of the bank-issued card.

I think you're mistaken. There is a swipe. It perfectly mimics the magnetic strip of the bank-issued card. The issuer wouldn't even know you didn't use the real card.

It wouldn't work for physical imprints, but neither does my Chase Sapphire Visa card. Point being even card issuers are comfortable EOL'ing physical imprints at this point. And it's not used for anti-fraud these days (real-time authorizations of swipes have replaced that); it's just a backup for when merchant systems are down.
Assuming that scalping is legal, and doesn't break some contractual agreement with the ticket seller, it is not "hurtful".

What is best for society is not to give things to those who want/need them most, but to people who are willing to pay the most for them.

This is the first welfare theorem. The "suits" earned their money, and what is the point of earning money if you can only use it to buy things other people don't want? If you want to do redistribution, then it should be done fairly, through taxation, but after the redistribtution is done, there is no better way to distribute resources than on a willingness-to-pay basis
Bitcoin has a long way to go in terms of proving security (not algorithm security, but practical "in use" security) and convenience before it it's a Blu-ray/Netflix dichotomy. These last few weeks, with millions of dollars lost in bitcoin hacks reinforces that perspective, I think.

> It's a positive development that admission into a decent PhD program requires research experience.

No, it really really isn't. The vast majority of undergraduates have no effective access to research experience, even many that are fairly inquisitive and are receiving a pretty good education. This is especially true of undergraduates who are unable to afford tuition at top institutions (and increasingly even in-state public university tuition is unaffordable for the flagship universities that would be considered "top institutions).

Requiring research experience in advance of grad school turns grad schools into an elitist echo chamber.

No. Most database engines are actually so old they were developed even before HDD hit the seek wall.

The perverse ethics of the author were apparent from the start "[I operated in a time] before you had to show ID, sign a slip of paper and answer a battery of questions from the always skeptical supervisor." The offended tone of the author is hardly appropriate given that this batter of questions was designed precisely to prevent scammers like the author, and indeed made necessary by people like him.

Anyway, theft is theft whether it's against a large corporation or an individual.

I can understand that people don't feel sympathetic towards large corporations since they never seem to be criminally liable when they break the law. However the answer is surely to enforce the law equally no matter who the criminal or victim is?
I think the pre order issue is that most credit card companies require that a pre order is just an authorization on the amount, not an actual transaction. The money isn't supposed to change hands until the item is shipped.

Coin is completing the transactions and using the money to fund their venture.

It probably isn't black and white either. I am no expert on credit card transactions.

I'm not too worried. I ordered one.
Seeing as those are still up and haven't been removed, I'm guessing the Coinbase app was removed for quality reasons. I used the thing and wasn't impressed. The experience wasn't great. Hopefully if they fix it up and resubmit the app, Apple will allow it back in.
Fine-grained locking is hard, but "tar pit" is unfair and honestly a bad attitude. It's crucial for modern applications, and it can be done if you're careful, and it can be done really well.

We (Tokutek) tried for a long time to get by with a big monolithic lock, and a) competing with InnoDB was really hard since they do concurrent writers really really well, and b) when we did decide to break up the lock, it wasn't as hard as we thought it would be and it worked really really well.

Don't get discouraged, break up that lock!

This is for installing tmux in Cygwin on Windows. Installing tmux in Ubuntu is as simple as searching and installing tmux from the Ubuntu Software Center (or apt-get install tmux).
I'm not sure how these students are filtered out at other places, but in Brown's CS department, PhD students are required to pass a "programming comp" that involves a fairly intense week-long programming project. You don't need to be a superstar coder, but you do need to be able to program effectively in order to pass.
From reading the two (slightly) sensationalist stories on Hacker News, you might think so. The thing is, SF has a larger community built up over many years. And the DevShare program was piloted by literally 3 projects to see how it would work, what the income would be, and what the reaction would be.

You or I could have told them the reaction among the tech savvy, of course. I did after the fact via a detailed set of reasons why it was the wrong approach and how it could be made much better if they were going to go down the offer-based path.

As for the ads that were the other reason GIMP left, these fake download button ads are everywhere. All over Google AdSense and every other graphical ad network. And banning the specific bad ones is like whack-a-mole. That's one of the reasons PortableApps.com only has text-based ads. I'm glad SF set up an email address to report the bad ones, but it's going to be difficult for them to weed them out.
Actually, I might have this problem. I don't use a lot of credit, but I carry around a primary CC, a backup CC (that is never used unless the primary CC is stolen), a corporate CC, four debit cards for various accounts, and a myriad of other things.

My kingdom for a solution that gets me down to one card.
Most credit card processors will have problems with you if you don't ship a product within a certain time frame (3-4 days) within charging a credit card. I believe its part of the TOS.

And consumers are different than creditors. There are different laws that protect each.
That rule absolutely still applies today. It gets a little fuzzy in some situations. I wonder if ETrade has to give apple a cut since Etrade makes money on every buy/sell transaction... or the Amazon shopping app...

P.S., I just signed up with coinbase.com 2 days ago and entered in my bank details. My heart stopped when I saw coinbase on the frontpage of HN; given the kind of news we've been hearing about bitcoin-xchgs these last few days...
But cygwin isn't linux, and on 99% of actual linux distributions you will never have to compile tmux from source. A better statement would be "And people wonder why Windows never became mainstream for developers."

Steps to install cygwin on actual linux? "(package manager) (install) tmux". And on OS X? Install brew by copy and pasting a command into terminal, then "brew install tmux". Even if you're an average consumer you could complete both of those steps without a problem. (Then again, why would the average consumer want tmux?) Windows/cygwin is the problem here, not linux.

If I may, I found the NSF GRFP process unsatisfactory. For example, I was rejected for two reasons: 1) because I did not publish prior to applying, and 2) because the reviewers thought that my research, although it had intellectual merit, did not have broader impacts (i.e., "the potential to benefit society and contribute to the achievement of specific, desired societal outcomes").

I proposed research on how to improve upon string searching, which according to the reviewers, did not benefit society (??).

The reviewers all have PhDs, I believe. But somehow, I do not feel they are qualified to review the applications. They are looking for specific things cross the check-boxes.

The second point is that stipends are taxed. So, $3k looks like a lot, but post-taxes, it's trimmed. Also, if you look at the OP's posting, $300k for ~5 years for a student. That does not mean the student receives $60k/year for living.

The third point is that someone immediately out of undergrad at 20 might find PhD / below poverty level stipends enticing, but once you make 150k+, you really don't want to hand control of your life over to your advisor's whims.

The fourth point (which is a corollary to the third) is that I know quite a few miserable PhD students, whose advisors control large aspects of their life. For example, a few of them were house-sitting their advisor's newly purchased mansion overnight in sleeping bags. These were foreign students.
