You're looking at Jiro charging $600 a head (looking at his website, the course starts at $350 but let's assume an average $600 for the sake of the argument), but for every Jiro there are other 50 sushi masters out there who are probably as good as Jiro (†), are charging only $60~100 per person and still have empty seats every night.

(†) If we are to trust Japanese TV shows, most TV celebrities can't tell a $500 sushi from a $50 one.
Am I missing something?

From the article: "At home, where money is tight, his family has two laptops, an Xbox 360 and a Nintendo Wii, and he has his own phone." (emphasis mine)

This is a family "where money is tight"?!

Whatever point the article is trying to make about the "digital divide" is obscured if they believe that a poor family is one with two computers, two game consoles, and where each kid has his/her own cell phone.

Don't have any ideas as for names.

However, I am a research mathematician and I would gladly pay money for something good like this. Please feel free to contact me (e-mail in profile) if you want to hear my definition of "good".
A Few things:

1) For some requests, the correct response can be hidden and just reply 'pass' or 'fail'.

2) You can use javascript to randomize the requests. For example create a random expression and ask it to be evaled

3) Candidates submit the code after completing the challenge.

Thanks for checking out!
We've been doing something kinda similar in LedgerSMB with versions of PostgreSQL going back to 8.1 when it was current....

Our approach was different though. We have object methods explicitly mapped to stored procedures by name (this is done to limit the stored procedures exposed by the application). If the number of arguments changes, the middleware does not need to be updated.

The queries are then called through an interface that, in essence, hands a hashref (in Perl) and a stored procedure name to a mapper function which then looks up the argument names and assembles the query.

This is then called, with an optional order by clause, and the results returned as a list of hashrefs.

While this isn't the exact technologies listed here, the approach is something I have found wonderful and so it's probably worth sharing.
This could work. I don't see it so much as an alternative system as further constraints on task/project generation and scheduling of GTD.

Well, regardless of whether it's new or derived, there does seem to be some merit to its focus methodology. Ironically, the thesis ends up being that one has to add rather than remove constraints to GTD to make it more suitable for creative work.
Best approach is to not build queries by concatenating strings. Use parameters if at all possible.
> by acknowledging the mastery, we have changed the practice.

I'm somehow (without irony) enlightened by this statement.
Reinventing the wheel is part of the fun. Recommendation algorithms are not that hard once you know the math behind. But, sure, it goes further than being a Rails dev.

What's wrong with a 1:1 correlation, when it makes sense? If what you need to do is to access or modify data, then a stored procedure language such as PL/pgSQL is perfect for the job.
But if you need to render some graphics using GD in PHP, that's obviously not a job for the database.
The total API of a system is probably not only stored procedures, but quite a lot of API methods, stored procedures can take care of the entire task, without the need to involve PHP or any other middle-layer language.

Just to be clear on the Software is now 10% of your working life for those who may not have understood

You need to make around 15 man hours fit in one of your work day. This is between coding, managing clients, dealing with bureaucracy, etc

I have to say as someone that worked as a consultant (for one client, which makes a lot of the bureaucratic/client management work simpler) one of the biggest time savers I has was hiring an accountant (instead of doing by myself)
What you suggest raises several important issues: first, we'd expect of these companies to go the extra mile of taking our money and redistributing to the rightful owners (which costs, it's a great deal of work to find out who owns what, be it in the music or movie industry).

Second and most importantly, there would be no way for us to guarantee that the donations you make go to them and not us. We'd get shot down because we'd then try to 'profit' from it. Which we don't and we won't.

So nope, no donations directly on the website, ever. However, we'll start displaying legal offers (Netflix, Hulu, Amazon, etc.) for US visitors, and we're working towards featuring Open / Creative Commons / Libre movie content.

Sounds like a good idea, we'll try to find some time to do that.

In the meantime, we've added a few restrictions as to which movies can be featured: they must have an artwork at TMDb, and a rating of over 5/10.
And that, my friends, is the miracle of capitalism.

How true.
Agree with you apart from "non-competing". They may not compete in terms of who wants to fund the research, but if both are successful then they would very much be in competition with each other.
I think you'll have traction problems on the developer side.

Doesn't matter what kind of job it is, you can be pretty much 100% guaranteed that the job will be listed on the company website without any of the extra hoops to jump through.

Requiring someone to build a web app just to apply is a huge requirement. It's fine if you gave someone an interview, and this is the final step before you hire...but requiring someone to code just to submit an application is abuse.
"Print the tweet given _its_ Id"
Why is Gold so Coveted?
Yes! I think the complexity should be reasonable too. I've listed why I built it here: http://www.cull.io/why.html

To start with, if you are recruiting a web developer it can be an simple alternative which lets candidates choose any framework, language or library.

P.s: It is another reason why cull.io never tracks the time a candidates take to complete the challenge. Honestly I think services like this will merely be a way to filter out candidates not select them. To select candidates you still need to work with them on a project and see their previous projects

My guess is that rich parents take their kids to the zoo and violin lessons and what not, while poor kids have more time to waste on Facebook and Angry Birds. Not too surprising or alarming if you ask me.

The real digital divide is between creators and consumers. I'd like to see more effort to get kids to create with computers. Like programming, but also writing, drawing, etc.
Rather than a rebuttal, that article was almost entirely devoid of any actual content.
ThinkPad X1 Carbon (which is their answer to the MacBook Air - similar size to the 13", but 14" with more horizontal resolution), or the 12.5" X230, which is a bit heavier, but has 60WHr+ battery options and IPS display (both missing from the MacBook Air).
It's a pretty nice idea. That music is beyond horrible, however.
>How are we to parse all this information? Do any of these people know what they are talking about? And if anyone does, how can we know which ones to listen to? The research of Dunning and Kruger may well tell us there is no way to figure out the answers to any of these questions.

Yikes, that's a stretch. Dunning and Kruger's work tells us nothing about our ability to assess others' competence; just our ability to assess our own. This idea of trying to apply that to arrive at "how do we know which experts to listen to?" is really reaching.
You should check out WeekPlan, it's a good tool to manage that kind of workflow (and made by a HN'er): http://WeekPlan.net
Maybe yours aren't, but mine are. I've been using this simple tool for three years now.

It gives you an extra safety net, in case the version in the database would differ compared to the version in the VCS, even though they shouldn't, someone might have been evil behind your back. :)

PgDeploy lets you preview the change and show you a diff.
If the diff is expected, you can proceed and deploy.

Comment to the author: use cmd-` while you are command tabbing if you go too far! Similarly useful, hold cmd-tab and it will stop at the end. Also, cmd-esc if you decide not to switch.

I used a 15" MBP for a long time without missing a tiling window manager that much... but the problem was exaggerated when I started using a 27" imac. So I looked around and started using spectacle. Great utility. I use Quicksilver's "open application" custom triggers to get the app switching behavior, so I finally have a use for F15-F19 (on the very left side of my keyboard)! It has made a big difference for me.

One problem I would like to solve is switching between multiple emacsen. I have an 8:00-5:00 job and work on my own stuff after that, and I like to keep my buffer lists separate (so I can't just use multiple frames). Therefore, I open emacs again from the terminal and I wish I could switch between them with quicksilver's shortcut. Alas, quicksilver always brings up the first one. Has anyone dealt with this?
I agree with you about API's (and would further note that stored procedures are a way to build API's around your database, as are views).

However, I disagree that stored procedures are a bad thing. There are several ways that stored procedures can be used.

1) Named queries (An API around your db!)

2) Set-intensive operations are really best done in SQL. You can do a heck of a lot (of even multi-stage logic!) in a single query when you throw in some in-line views, common table expressions. Writing in stored procedures gives you a single, testable reference for functionality.

3) Exporting application functionality to other programs that may want to use the db (like Excel for example).

4) Unit tests in the db are very, very helpful and highly underrated. Gotta love the fact that rollback means "none of this ever happened."
People want to eat meat. Pink slime is a small amount of meat with large amounts of the bits you'd normally leave behind.

I'm not against mechanically recovered meat. But I'd prefer children to get chunks of real meat cooked well than a squirt of slime and salt and flavourings in a crumb coating which is then fried and served with a sugary sauce. (ketchup, bbq, etc.) That combination of fat, salt, and sugar makes food "hyper palatable"[1] and, while much cheaper than "real" food contains little in the way of useful nutrition.

[1] Not my term. It's used to describe food where the balance of salt, sweet, and fat have been carefully balanced, and where the food is very easy to eat, because it's small or soft and easy to chew. See the progression from roast chicken, to deep fried chicken, to deep fried chicken with a salty coating and sauces, to "popcorn chicken" which are small chunks of meat, with a lot of fat-soaked salty coating.
It this part of the LedgerSMB project? If so, what part of the source code handles things? Would be interesting to see how you have implemented it.

When you create a new function, do you have to do anything in addition to do CREATE FUNCTION, before you can use the function in your front-end/backoffice/whatever external system component?
I really like this idea. I'd be interested in helping out with this or something like it.

I think he's saying Java is fast (compared with Python at least).

The point is, if you assign nearly mystical properties to writing in C, but when you rewrite a brute force approach Python program with a much fancier algorithm in C and you "only" get 10x speedup then something is amiss.

As a high school teacher, I see a clear difference between students who have internet access at home, and students who don't. I see a difference between students who have guidance at home in how to use the internet appropriately, and those who don't.

Students who have access and guidance at home spend their online time at school focused on learning. Technology is a tool for their learning. Students who don't have access or guidance at home spend their time in school learning about the technology, rather than using the technology to serve their learning needs. Students who don't have access at home also spend a lot of time trying to avoid learning and use facebook/ youtube etc.

The "digital divide" concept is messy, but it is real.

Perhaps money is now tight (nothing left for a contingency fund or retirement savings), because they spend so much on frivolous amusements?
I agree with you. This trend in our field is really making me uncomfortable. Judge me on what I know and what I did before, no more, no less. Or, to make this even more futile, how about I ask the company to build a small app for me? Since I also want to know if I should work for them. If they think their main business is enough to judge them, then my past experience is equally enough. This is bordering ridiculing in my opinion.
Yeah, I'm American (from New England) and I've gotten that. I was on my way to a small town in Pennsylvania, and my car broke down part way. It was late, so I had it towed to a garage and found a hotel for the night. In the morning, I decided to walk to the garage (it was a couple of miles). The guys at the garage looked at me like I had two heads for walking that far.
That was my initial reaction when reading the title. Actually watching the demo video shows that expected work done is more akin to pre/post interview coding tests.
You need a few points yourself first (no idea what the threshold is). Post some interesting items or join in the debates in the "comments".

I think you can probably see that this is a guard against "sock puppets" being used to promote spam posts.
There's an even easier way to do static sites on heroku and have them compiled for you - use stasis (http://stasis.me) - I've built a framework on top of stasis and have been using it for months, as part of very large production sites, and it's been extremely stable and super easy to use.

All you need to do to get them working on heroku is include a super basic config.ru file, and you're all set. The files compile into a public folder which heroku uses to serve them.
This is what I do. Works great!

Ummm....

Essentially electrons must travel around in a circuit. Sort of like a racing car. Electrons can't teleport from one location to another, and the number of electrons in a circuit will never change.

If touching you touch a wire, and you don't make a circuit (a complete loop) then you will receive no current (electrons can't move in a circuit), thus there is no voltage (since V = IR)

Usually when you touch the active wires in a powerpoint a circuit is made:

from the powerplant to the powerpoint,
from the powerpoint to you,
from you to the floor you are standing on,
from the floor back to the powerplant.

A transformer works by having two coils of wires, and when electrons flow through one coil, it excites the electrons in the other coil, and they start to move too. (This is done through magnetism).

A transformer is usually used to change the voltage of an AC source, but in the case of the "Isolation transformer" the voltage on the input side and the output side are the same.

In a transformer, the two coils of wire aren't actually connected to each other. So if you touch one of the output wires, you don't make a circuit, as the electrons need to get back to the other output wire for a circuit to be formed.

The same thing happens with a battery. Unless you are touching both terminals, there will be no current flow.

Are you suggesting that there is no need to have open file formats? No need to use more than 1 app on a single file?
I think it was two things mainly:

1) Pictures of mechanically-separated meat (the pink soft-serve) misattributed as LFTB.

2) Hysteria around the use of ammonia, which people read as "poison" rather than "food-safe antimicrobial agent".

It was a dark day for reasoned discourse.
Ha! I never thought anyone would use that. It's basically a simple fork of their PHP buildpack that stops caring if it's PHP and just serves off of Apache. Perhaps I should clean it up.

See also "Beating the Averages" by Paul Graham and The Blub Paradox described in that essay (http://www.paulgraham.com/avg.html).

One should always learn other programming languages, especially ones with a different paradigm/approach. You can be certain that you are a Blub programmer: there is always (or will be) something better than what you currently advocate and cling to, especially better given the task at hand (there is no universal silver bullet, but there are specialized tools).

The book mentioned, "Seven Languages in Seven Weeks" is an excellent place to start and I highly recommend it.
Thanks ticks. Out of curiosity I'd love to know what do you think should be the best way to filter developers when you make a Job post.

I used to do the 7 Habits style but found that I was constantly moving stuff from one week to the next when I didn't finish.

I switched to GTD a few years back and am much happier. I won't claim to be a perfect GTD adherent, but the brain dump + 0-inbox cycle theory works great in practice. I no longer constantly worry about "I need to remember to do X" since I have set up tools that allow me to place all action items in an appropriate place.

While I used to try to always do stuff quickly to get it out of the way, using GTD style to get it persisted somewhere allows me to be sure it's captured and then not care if I never get to it.

Where GTD falls down for me is that I have so much stuff in there to work on that it just can't prioritize for me. But it's not supposed to. My challenge since adopting GTD has been figuring out what context to be in.

I like TFA's comments about augmenting GTD with his technique to help decide what to work on. Context selection is prioritization and he has found an interesting approach to achieving focus that gives you power to ignore interrupts.

UX is a problem, but eliminating files just creates other, in my opinion much worse problems, namely that all "files" or "documents" are tied to one specific application.
