ok not a fan of the ticketing idea, reasons have been rehashed here a dozen times (venue lockout, ticketmaster/eventbrite, brown paper tix, etc)

Social media reporting, this is a tough one, as someone who built an early social media reporting tool years ago, I'd say the market is tough to get people to pay for the functionality. However, if you can get the right clients they will pay large sums. The market for this is very fickle and competition is tough (salesforce/radian6 for one). One key thing I learned: small business/midsize biz don't have enough chatter to validate spending on reporting yet (imagine how many people are talking about John Doe dry cleaner in San Juan on twitter on a given day).

When giving a written test on some theory subject, I sometimes let students take in their own hand-written notes on one side of an A5-sized piece of paper, then hand it in with their test. If students are going to sneak in a piece of paper stuck up their sleeve, then why not let them all?

Firstly this kind of vulnerability requires no white-boarding. It is fair to assume that a dev with a reasonable understanding of how the web protocols work will not need a white board to figure this out. So firstly the argument of catching this on a WB is a little juvenile.

Where would you sell it? Personally, without some kind of app store, I probably wouldn't have bothered with redoing the design and making an icon and all that.

If there's some kind of app store or if you're willing to build your own storefront, I say go for it (but what do I know?). If you don't have a job anyway, what do you have to lose?
We are encouraging companies to bring their engineers and recruiters, so that you can talk to someone who knows what you're saying and talk to someone who can actually continue the hiring process.

This is my favorite response. One of the reasons I came to HN from Reddit was that the proportion of populist/echochamber articles and comments to well thought out and insightful articles and comments changed unfavorably imo. It makes me sad to see the trend continue on HN, perhaps it is inevitable.

My frustration with this article is that while it makes some valid points that could well be articulated as things to watch for, it instead takes that to the extreme and generalizes a single person's biased experience to the notion of a more universal truth. Unfortunately the world is much more complicated than these type of articles like to admit.

Yes SQL is well known, and solves some sets of these problems, but it also introduces other problems that can overwhelm depending on the environment and the scale. As an example, at my last job I worked at a company that worked in banking and mortgages. They tangle of banking and mortgage laws is different state by state, and in some cases county by county. At this particular company an unusually large percentage of the people know how to write SQL. So vast amounts of business logic were written into SQL. This was stored variously in stored procedures, DTS steps, SSIS Steps, Excel VBA Functions, Access Functions, etc, etc, ad nauseum. May not sound like much until you realize that we counted 50 thousand excel documents on the network stores, 10 thousand access databases, 10 thousand stored procedures, etc, etc. This was for an IT team of about 20 people. Does this mean SQL is an anti-pattern? No, it just means that tools taken to the extreme and used well beyond their design tend to stop functioning well.

ORMS certainly have their problems and can definitely slow things down. However almost all of those arguments could be and were used to argue why assembly was better than C, why C was better than Java, why Java was better than Ruby...almost seems like a pattern. ORMS can save you on maintainable code footprint, and can reduce complexity if they are used correctly. Of course that doesn't mean they can unthinkingly be applied in every situation with no design. The contra is also not true. Unthinkingly applying SQL in all situations is just as perilous and fraught with issues.

I suppose it is against human nature, but I wish for the day when people could have reasonable discussions about issues, recognize that other people have some valid points, and possibly learn from each other and not feel the need to over-sensationalize everything.
Forget pricing model for now. They are big companies so you can basically charge whatever you want if there is a need.

Focus on figuring out if there is a pain.

I remember reading that some company had built this on springwise or sprouter weekly. But it was a hardware device which had to be installed in the theater so you could beat them by price.

Bottom line: Write up a proposal (4 slides of how this will be used) and then hammer linkedin to get an interview with someone who is slightly executive at a movie theater. Do like 10 interviews. You'll know by then if there is a pain.

Also research that company I mentioned above.
"In a large gathering he feels lonely and lost. The more crowded it is, the greater becomes his resistance. He is not in the least 'with it,' and has no love of enthusiastic get-togethers. He is not a good mixer. What he does, he does in his own way, barricading himself against influences from outside. ... Under normal conditions he is pessimistic and worried, because the world and human beings are not in the least good but crush him. ..."

Thanks for this quote. I feel that all of the discussion here of how being an introvert is a quirky personality trait and a fun expression of human diversity makes a mockery of people with social anxiety.

> The time spent learning the course would still have been spent, had one not used this special method of revision

Not necessarily true. He specifically lists learning and understanding concepts as they were taught as a part of his strategy (his principle #1). I adopted pretty much the opposite principle - not putting in too much effort during the term and learning it all at the end. So I would presumably have put in far fewer hours during the course than he did. So comparing my total revision time to his would not be a fair comparison.

Incidentally, this wasn't a deliberate strategy of mine, it's just how I liked to do things, but I think maybe having the full content of the course before I started serious learning may have been a benefit.

I also spent a lot less time on revision than many of my peers, so I don't think learning during the course is necessarily a prerequisite for minimising time spend revising.
I love having a solid hour for this, but can't always make it happen.

Do you see the hidden narrative?
I get your point now. You are right there should always be some communication. In the case of my friend, it's cool, but for others it would be helpful when they read something like this.
And even those who are in there primarily because they want to learn will be very aware that getting a good grade in the exam will most likely improve their job prospects on graduating.

Learning to ace an exam in the minimum time possible frees up the rest of your time to do some actually useful learning.
It would be great if the article had a proof of concept (or at least a more detailed explanation). I don't feel like doing it myself to verify if it's true, and put my account at risk at the same time.

"there is not a whole lot you can do to tune your queries"

What does this even mean? For any query which relies on data from different tables, yes there are opportunities to tune the query, and there are opportunities to build different kinds of indexes, and there are opportunities to de-normalize the data and remove the join completely. This is independent of your RDBMS vendor.

The statement that Oracle/SQL Server are 'high quality' and the implication that open source RDBMSes are not, is flame-bait. All RDBMSes (that I have experience with - including Oracle and SQL server - so caveat emptor) will hit a performance wall when an index becomes invalid and the engine has to table-scan - and indexes can become invalid automatically as the amount of data in the tables changes - typically this will happen at 3am in the morning when you are on call.

There is also the hardware that the files are stored on, and the balancing act of price/performance of splitting tables onto separate spindles, using SSDs for semi-hot tables, cramming in more ram, upgrading the network connection between db and app servers etc etc. Every real world application needs constant tweaking from query to hardware as bottlenecks appear in different layers. Again these issues are almost entirely independent of the RDBMS (apart from with SQL Server that only runs on Windows, so the deployment platform is limited by what Windows server supports).

Nonrelational datastores can also hit performance walls too - the fact that some of the nonrelational stores are newer also has the added 'fun' that the performance characteristics are not completely known.
Well, the article said "any paypal account", and I can't get it to send a reset token to an unauthorized email, so at the least it seems that either the claim was wrong, or they fixed it.
When a manager starts off with small talk, it only increases my anxiety more than any straight question ever would. I'm always waiting for the other shoe to drop. I've seen the pattern in every job I've had before my current one and with most teachers and professors I've met. They start off talking about something unrelated only to hit you with a hammer with the next question.

Out of place small talk doesn't actually help people that are perspective enough to realize you want something. My experience has been that when a manager randomly starts a conversation that's not work related when it's not lunch or break time they are going to be asking or demanding things I won't like. Infinitely so when they just called you into their office.
This is rather scary.

Surely my bank would notify me though if my credit card started getting hammered. I don't suppose I'm the target thieves would be looking for though, it'd be those with large balances sitting in their account.

The article is rather light on details though, I wonder just how true it really is. That said, they have nothing to gain (other than impressions) for running it.

"We are four faster than Hadoop on the Thor side. If Hadoop needs 1,000 nodes we can do it with 250 – that means less cooling and data center space."

Many (most?) Hadoop jobs are IO-bound. It's unlikely that switching from Java to C++ could speed those up 4x.

We should reserve judgement until these things are actually open-sourced.
I've been using datamapper recently - I like it, but would be interested to hear what makes you like it so much over the others (which I haven't used, except for a smattering of ActiveRecord).
It doesn't say how they are sending it to an unauthorized email, maybe their is some hidden value in the form that they are sending to allow it or something altogether different to get the reset email.

Just because you can't do it doesn't mean it is fixed.
Against my better judgment I went to a theater that's notorious for being a teenage hangout.

I, like you, can maybe think of one other bad experience I've had at the movies before this weekend. Tattlr certainly wouldn't be an everyday kind of app. Heck, one may only use it once or twice a year. However, I think there's value in the peace of mind of being in a large dark room knowing a theater attendant is only a couple screen taps away.

Floats were originally intended to be used for floating images inside text blocks, not for layout purposes.

The usage of floats all over the place is no longer justified since all major browsers support now inline-blocks and CSS tables.
For hardware based sorting, we can do even better using sorting networks[0]. Sorting networks are comprised of a system of wires, one for each input, and comparators between wires which always output the higher number on the bottom wire and the lower on the top. Using this framework we can do massively parallel sorts with excellent time complexity.

The problem is that sorting networks need to be designed for each input size, and designing efficient sorting networks is an open problem. There has been some work in the evolutionary computing community on sorting networks, and some of the best known networks for various sizes were found by EAs, but large networks are still a challenge.

Naming your company is easy. Just do the following!

- append -ly, -able, -r, -up, -in, -on
- remove all vowels
- substitute k for c unless it ends in -ck in which case just remove the c... or the k
- take the last two letters and put them into the doma.in
- prepend with get- or the-
- use a sound

And, if all those fail, just buy the domain you want with .net instead of .com and buy the .com after you've raised some cash. ;P

I don't have any information about this other than what's in the article. However, as a proactively paranoid precaution, I've chosen to temporarily de-associate my company's bank account from its paypal account, just to make it impossible for an attacker to drain those funds.

I know that if this does turn out to be a legit security issue, Paypal's engineers will soon deploy a fix, after which I will just re-associate it.

The procedure is:

1) log into your paypal account
2) click "profile"
3) Click on "My Money"; or if you don't see that, look for the subheading "Financial Information" and click "Bank accounts"
4) You should see a link for the bank account; select it
5) click "Remove"
6) *confirm* on the next screen (be sure to click that "confirm remove" button)
7) See the confirmation message

That's it. Depending on your Paypal balance, you may want to try transferring funds into the account before dissociating. [EDIT: Or maybe not, sounds like it could block the disassociation procedure - check the comments below.] I don't know if you can do both in sequence quickly; fortunately our paypal balance happened to be really low today.
