While I agree the application process needs improvement, I think this entry greatly exaggerates how hard it is to get into a PhD program. Since when do you need to be published to even get into a PhD program? When I went through the application process, I got accepted by 6/6 schools that I applied to, with no publications and no real ideas for what I wanted to research on. In fact, most PhD students actually don't even have a research topic until the second or third year of grad school. I think more than anything, your personal statement is the deciding factor in a lot of cases. What had worked for me was to have a list of research topics and faculty from each school that you're interested in working with, and directly address them in your statement. Other than that, of course whatever supporting evidence to differentiate yourself is helpful. I thought proposing to use offer letters from Google or YC (both have much lower acceptance rates than a PhD program) just to prove you can code is pretty hilarious.

I'd made a faraday cage with tin foil in my backpack to thwart the tag alarm system, and tested it out on a large retail electronics store. So yeah, maybe it doesn't require the social skills needed for the author's cons, but it did require technical skills.

That said, that was a long time ago when I was a troubled kid. Now I'm a voluntaryist, and I see that stealing doesn't fit with my set of values. Perhaps I picked up some valuable lessons while experimenting with anti-values.

As for the author, it seems that he never really grew out of it. It's clear that he derives pleasure from cleverly conning people. It's a shame, because that mental energy could be used for good instead of what amounts to scummy behavior.

There is so much more pie to be had when you can bake it yourself, rather than having to con it from others.
Couldn't agree more. 10 products launching on HN today to solve convenience issues so you can pay for your $7 croissant and decaf soy milk latte with vegan cinnamon and not be forced to carry around 4 credit cards. Good god.
Oh that's cool - might be some way of integrating that into my site in the future.

One of the core differences though is that TransitFeeds is primarily for browsing and discovering new feeds to interact directly.

The API is more of a value-add so devs can automate their own build processes, or in the case of something like GTFS-RealTime, making the data into a mobile-friendly format (a single GTFS-RealTime snapshot could be say, 2 MB big and contain information for thousands of vehicles).

Why do you need to carry around four debit cards and a backup credit card? I'm not saying this works for everyone but my wallet contains $20, a driver's license, and a credit card.

If I'm going to be somewhere where I might need a business CC or debit card then they're temporarily added. Otherwise I store all my CC info in 1password anyway which I can access on my phone.
And don't forget AngularDart or whatever for the front-end framework. I wish the name "Google" wasn't attached to any of these projects as I'm a huge fan of them but not the company they're born out of.
Yes that was my first thought too; is there a lock/unlock gesture?
Hi, thanks for the comment. There is some ongoing development on predicting couple of main things:
1) Would a particular person be potentially a good candidate for certain role. This is done by using similar other profiles as a training set and use those factors to predict early on if someone would be a fit. e.g. People who have studied in a university of reputation X, have Y yrs of experience and have Z skills go on and achieve position 'A'. These factors would be used to predict the users who share the traits and would likely land in a similar position.
2) Predikt the probability of job hopping, likelyhood of someone being a passive job seeker, potential salary ranges the candidate falls into.

Right now, Linkedin and facebook integration are functional, certainly it would be more useful to add all possible networks. Github, Stackoverflow would be next. Some recruiters have approached and would like to use this for screening their applicants.
The idea is cool, but we already have the idea using mobile phone to check out. All we need is the ability to bring that alive.
Many US students do not go into PhD, because, as you mentioned, due to the strong job market (and also a 20k/year stipend). Most of the PhD students are foreign.
This is illuminating, also would be if you could add years to each slide that would be even more fascinating. Great work and thanks for sharing!
Well technically the part that allows you to pay is shipping next year...

Also this doesn't solve the problem that is being discussed in the coin thread of imprinting and buyer verification for the merchant.

Still, This is the technology that cell phones should be including on a hardware level, not the stupid NFC thing that doesn't work for most US POS. I don't have an iphone or else I'd be contacting them right now asking if I could get in on the action even though I'm about a week late!

What they should do is connect your cellphone account to this and that would allow the carrier verify your identity (if you're on a contract).... I'm sure there's more here that we could do, maybe have an option to silkscreen the your id of choice on to the back of the case...

People this needs to be made to work NOW!! I use the ninja wallet and even that is too big and bulky for me, if I could get rid of the whole thing and just carry it in my phone the world would be a better place!
The entire tone of the article is rather off-putting. Through portions of the article there tended to be this sense of having pulled one over on corporate America, when that is hardly reality.

One data point: Nordstroms. They will take everything in returns. For them, customer lifetime value add of a hassle free customer experience outweighs edge cases like the author who take advantage of the system.

I'm sure there were many instances of the author taking advantage of the bureaucracy of large corporations, but that's no particular feat of genius- that's a byproduct of bureaucratic systems.

I'm sure there are going to be plenty of places which refuse to accept anything but an actual credit or debit card.

I mean, there's no signature to check. What do you do when 10% or more of the places you go refuse to take this?

Heck, a lot of places used to require the cashier to type in the last 4 digits of the card visually, to make sure the physical card matched the stripe. I haven't seen that in a while, but that would also be impossible with this.

Are the credit-card companies on board with this, instructing retailers to accept these?

This is amazing, I love the DI with services! I always preferred Gorilla to things like Revel because it wasn't so opinionated, and this seems closer to Gorilla but with this clever idea of services.

I threw together an example app with templating and database access as services, I'm impressed by how concise it is.

My thoughts about Google+
Special thanks for mentioning Credit Score. The algorithm we are building is pretty much like a Credit Score algo. Not just because we show a score for users, but because we use factors learned and deduced from similar other profiles and use it to quantitatively predict the likelihood of a fit (risk in case of a credit score). It would be ideal to use larger datasets for training, however its still in beta and the algorithm is being updated continuously.
Thanks for the clickable link too :)
From the study's abstract:

"Studies of planned home births attended by registered midwives have been limited by incomplete data, nonrepresentative sampling, inadequate statistical power and the inability to exclude unplanned home births. We compared the outcomes of planned home births attended by midwives with those of planned hospital births attended by midwives or physicians."

and

"We included all planned home births ... and all planned hospital births meeting the eligibility requirements for home birth that were attended by the same cohort of midwives ... We also included a matched [my emphasis] sample of physician-attended planned hospital births (n = 5331)."

RocksDB has an LSM architecture, similar in nature to HBase, leveldb, etc. But the implementation is based on a Theorem that we will be publishing shortly. I am working on the Theorem with a colleague of mine.

Cache Oblivious B-trees is an interesting paper. Similarly fractal trees. Most of them optimize the case when index nodes are not in memory. However, in our use-cases, we typically configure the system in such a way that most index nodes are in memory.

For an LSM database, the key component is "compaction". You can ingest data only as fast as you can compact, otherwise u get a unstable system.
.1 RocksDB replaced the Level-style compaction of leveldb with UniversalStyleCompaction that has reduced write amplification. This boosts performance.
2. RocksDB implemented multi-threaded write, which means that parallel compactions on different parts of the database can occur simultaneously. This boosts performance.
3. Bloom filter for range-scans: this boost read performance
4. MergeType records that allows higher level objects (counters, lists) use only-write instead of a read-modify-write. Improves performance.
5. And many more...
As in most areas of life, you get what you pay for.
Well, I just installed this. I always assumed tmux wasn't compatible with Cygwin, but I guess it is.

Note that you can skip steps 2 and 3 if you install libevent-devel and libncurses-devel in step 1. The Cygwin provided versions of these packages are good enough (in fact, libevent is the same version.) Also, I didn't get any warnings when running autogen.sh, but I have all the available versions of autoconf and automake installed, so that might be why.

The content is free, you pay monthly for the coaching and a certificate once you're done. I don't think the courses come and go. From what I've seen, they've only added to existing courses, and have yet to remove any of them.

He has just been stitched up by three critics in one of the The Danish Committees on Scientific Dishonesty which lurk in The Ministry of Science, Innovation, and Higher Education. In the midst of all this horrible nonsense, which has already caused him a lot of trouble and cost him his Emeritus status, I cannot help but be distracted by the funny names education departments give themselves. Innovation? I suppose a Committee for Public Safety is an innovation for Denmark, but the Jacobin terror got there first.

Unfortunately, though, this kind of goes against your argument which I understand to be "how dare Google release something that is not standards based". I agree principle with that, _but_ in this case a few posts did show example of technologies that all browser vendors introduces that were outside the spec.

> But in recent years, there is growing consensus on the importance of not shipping non-standard things.

Others might read that as no new and meaningful technologies will be seen implemented in the browsers soon. I can't think of too many thing designed and build by an intercompany commetee.

When I was in neurology, my favourite sales rep was the guy who would answer a question with "I'm not sure. I'll find out and get back to you". He didn't always get back, but he usually did, and you were better off for it. Much better than the sales reps who gave you a bit of hot air masking that they didn't know the answer.
This is an excellent question. RocksDB has a lock per shard that is used to protect incrementing/decrementing refcounts on critical metaddata structures for writes. It is never held during actual IO to storage. We have been able to saturate a flash device for a pure-write workload when value size = 800 bytes without bottlenecking on this lock.
I have the same concern about #3 and even the viability of the certificate/coaching tier. They need to make a pretty compelling case for the certificates as a valid path to employment.

Though, I'm happy that they managed to find a strategy to monetization without blocking access to existing course material.
I noticed a few years ago how much information, and questions companies wanted for returns. Well--now I

the receipts will disappear, and the customer will forget

disgruntled Store Manager--Costco--a grey market watch.
The most dishonest(stealing the most, internal theft) is
usually the Manager; followed by employees. It's a little

are their employees, and customers stealing so much?
Unfortunately, the trailing six months isn't a meaningful figure given the annual seasonality of the niche. Value would be over stated in the spring (when profits are high) and under stated in the fall (when profits are low).

And while, theoretically, it could be possible to create a ton of fake transactions to boost the sale price, it'd sure be a heck of a lot of work for little payoff. You'd need legitimate transactions, otherwise you'd simply be returning the motors and reducing revenue.

I suppose I could start a trolling motor MLM and ruin all my personal relationships to boost my chances at a slightly higher sale price...
I would suggest installing Vagrant instead. (http://www.vagrantup.com/)

For example:

Start your new Ubuntu machine...

$ vagrant init precise32 http://files.vagrantup.com/precise32.box

$ vagrant up

SSH in..

$ vagrant ssh

And install tmux

$ sudo apt-get install tmux

*note: these commands are off the top of my head, please read the getting started guide for proper instructions.
I'm a PostgreSQL fan, but Oracle are investing in MySQL development, but their flavour of open source compliance is tarballing.

5.6 had some pretty critical improvements, especially to the query planner.
I was interested in yours specifically because it's the only one I've seen that doesn't buffer (almost). You might as well drop the last little buffer and be completely bufferless. Then it will never cause an error or block, and you'll have no dependencies. If you want to support validation, make a higher-level interface to this and do it there. It will be just as easy.

This can be used as a drop-in replacement. It disk format is compatible with leveldb. But once you upgrade to RocksDB, you won't be able to switch back to Leveldb (unless you restore ur data from a backup).

One definite use-case for RocksDB is a message queue that has a high number of puts/gets/deletes.

Also, please look at options.h to determine what options to tune. A not-tuned system will not show you much perf difference from leveldb.
In our own workloads, writers are always going after the same pages in their index updates, which inevitably led to deadlocks in BerkeleyDB. As a result, we get much higher throughput with fully serialized writers than with "concurrent" writers. A microbench might show greater concurrency on simple write tasks, but in a real live system with elaborate schema, there's no payoff for us.

As always, you have to profile your workload and see where the delays and bottlenecks really are. Taking a single mutex instead of continuously locking/unlocking all over the place was a win for us.
I agree. This seems like essentially volunteer work for a company with no part of their business model validated, and no real working software.

Treat it like any other volunteer work: go for it only if it's something you believe in and are passionate about, and think you can make a difference.

No. octopus card is just another card but because people like using it so much places like 7-11 won't mind to have it. You load money into the octopus card (not sure if now banks allow account linking). At least when I was kid that was how things worked.
This is a total stab in the dark from a foreigner, but I though that it was only recently that US banks could be larger than a state-level entity. My entirely uneducated guess would be that with only state-level banks, none of them would have the pure muscle to push something as big as this.
Perfect example of selection bias.
The US hasn't adopted EMV because it isn't necessary. EMV was created because in Eastern Europe many businesses didn't have sufficiently reliable phone and internet connections to validate credit cards -- in the US we have no such problem.

The cost of rolling out EMV was determined to be greater than the cost credit card companies paying for the increase in fraud and chargebacks out of pocket.

Thanks for your comments Jon. RocksDB shares some of its genes with LevelDB.. something like a parent-child relationship.

I used to have JNI bindings that I pulled in from https://github.com/fusesource/leveldbjni but it was difficult for me to update the JNI everytime we added new apis to RocksDB. It would be great if somebody who needs Java support can implement JNI bindings for RocksDB.

When did you apply, and to what schools?

These days, good luck getting in a top tier institution for CS without a solid track record (I.e. a publication or two at an ACM/IEEE conference, and letters of rec from reputable professors/researchers in your field). The letters of rec are what make or break your application.

I agree that it's a bit over the top, but that's how it is.

I didn't make myself clear. I meant assume in the mathematical sense, as in, to take as an axiom. If you do a science experiment, you are assuming that you will get back a repeatable result, and you won't be measuring something perfectly random. Otherwise, people might assume you're crazy. :)
A more plausible reason for why Democrats would be more "partisan" is because moderate Democrats have been defeated by Republicans in recent elections, particularly in red states. This will likely be more pronounced if people like Mary Landrieu and Mark Pryor are taken out.

First, the profanity does not add any kind of flourish to your writing. I'm not the least bit offended by profanity. I'm just mentioning to you that your use of it is awkward, like toilet paper stuck to a shoe. Whether I agree with your point or not it just makes it worse than it would have otherwise been and does not add the zing or oomph you apparently think it does. It also feels to me a bit like the way a non-native speaker of English might mimic "everyman" use of profanity he'd seen depicted in a movie.

Second, for someone who claims to value community and society you are not engaging in a constructive discussion or making any kind of argument. If you have any intelligence or education it is certainly not evident from your remarks. No disrespect if you are actually educated or intelligent, but my guess at this point is that you are a 10 year old kid trolling for laughs and trying to learn Ruby on Rails.
