I just can't see it. Is it in the demo test?

My bottom left corner is empty. Except when I click "verify" it shows message whether the tests passed or failed.

But I don't see the tests themselves, nor did I notice a way of writing my own. I've tried it in Firefox, IE 8 and latest dev Chrome.

So, is it possible to write my own tests when I'm taking the test, or only when I'm creating a new one?
To think that a programmer will always come up with the exact and most optimal solution to any given problem is a bit naïve

I have no idea where you saw this being implied. The software highlights syntax and lets you check your code as many times as desired, as well as giving hints if your result isn't correct and providing compiler output. Nothing stops you from googling something. It's not like the software will destroy your file and egg your house because your algorithm is o(n2) instead of o(n); that's up to whoever is evaluating the results.

The fact that it has a polish and chinese version should also give you a little hint about the intended audience.

The New Economics Forum was searching for a press hit, it is a shame NY Times is confirming this truthiness[1]

sam.thompson@neweconomics.org

"However, I thought your piece was thoughtful and interesting, so I just wanted to make one point, which is that we don't claim that the index measures happiness (we emphasise several times, in fact, that it doesn't). Rather, we claim that it measures well-being efficiency: that is, the relative 'price paid' for experienced well-being by countries as a function of their resource consumption."

"To an extent we asked for this kind of (mis)interpretation by using the word 'happy' in the title of the report - we have wondered, with hindsight, whether this was such a good idea. The trade off is that we got a huge (and 95% positive) press hit - and that's all part of the game too.."

Sorry, some bug on our end - it should be there. We are fixing it right now. In the meantim - if you sign up for a trial account [http://codility.com/accounts/codility-register/] it works fine there (a blue "add a test case" button in the bottom left).
I'm not sure the timer is a good idea. For one, I found the seconds counting down very distracting. It also encourages quick and inefficient solutions that are easy to hack out, over more efficient algorithms that may take longer to code.

Maybe you should time the programs, instead of the programmers.
Everyone seems to be talking about and implementing location based services. It's an interesting area : but is the right problem being worked on?

I've needed to use a service like near me now just a few times in my life. Most of the time I do not wait till I am standing in a street in a particular place to start finding out what restaurants are around there.

A more useful service is this: searching within a crowded shopping street. Imagine you go to a shopping street, and there are crowds and stores everywhere. You could walk into all stores searching for that perfect bag, but what if you could just type 'bag' into your phone and it shows you all the hot bags currently being shopped at that street, and where exactly it is?

Real world searching is a good application of LBS. More useful than knowing the next restaurant.
Given the fact that it is about a 'mined resource' you could just as easily see it relating to the Middle East - especially since the US is actually engaged there at the moment and the troops are modelled on US Marines.

From an Australian perspective it would seem to be about the 'aboriginals' (the word is actually used in the film).

I'm sure there are many other interpretations.

Edit : I just read a review that thought it strongly evoked the Vietnam War.
Is the code editor they're using something publicly available? I'm looking around for a light in-browser code editor with programmer-oriented features (e.g. syntax highlighting, this also seems to auto-indent Python code to some degree).
We are timing the programs as well - with the scalability assessment. Recruiter can change the timing anyway, but we feel that a bit of pressure is good. You don't always have comfy conditions on the job after all.

I would pay generously to take a guided tour of Amazon's fulfilment centre. I imagine it to be a hive of activity. Most of us take next day delivery for granted now, but when taking into account the volume Amazon must process every day, I find it fascinating. Even more so when you take into consideration their same day (evening delivery) service.
You know, now that I think about it...The description of the test was pretty incoherent. If I don't know what my test data is, and if the problem description is incoherent, I can't really make it work.

It's also taking a metric fuckton of time to evaluate my solution. Which apparently fails. For reasons I can't debug because I can't see the test data.

Any company that relies on code snippets, incomplete problem statements and undefined test data to judge coders will get what they deserve.
Great :-). I feared I was too stupid to see it.

Anyway, I like it a lot. It sure beats writing tests in front of a blackboard.
I did, and now I see comments stating that you should be able to run tests on your code while developing it. That's awesome and what I was missing.
Next step intellisense and on-the-fly syntax checking. I hope no programmers click the "compile"-button nowadays to check if their code is correct...
I happen to be working on a micropayment strategy and implementation for my day job (we're content producers in this scenario) but we're US based.

I am curious to know more about the micropayment problem your startup is solving.

The technical issues--transactional processing, account management, integration with the web experience, etc.--aren't trivial but they are relatively straightforward.

The harder nut to crack seems to be the social issue: Customers don't want to break out a credit card for a $0.01 purchase, so you need some sort of digital wallet or debit account to deduct from. Yet there is no "digital wallet" service with broad enough acceptance to assume that your (or at least my) average customer will have one.

The chicken-and-egg problem seems to be a challenge: Sellers won't offer the digital wallet payment option if there aren't existing customers. Customers won't sign up for a digital wallet if there aren't sellers who use it.

Are you doing anything to address this side of the problem?

DirectDraw/Direct2D has been deprecated long time ago in favor of Direct3D. So basically you are in the same position as with OpenGL.
Occasionally I am in desperate need of a similar service: I might need a particular kind of screwdriver, for example, and therefore want to know the nearest store that sells exactly that item (and ideally has it in stock). As far as I can tell there's not even an approximate solution to this problem yet.
It doesn't really sound like this is what you're looking for, but Google has a really nice branch in Sydney. Sadly, immigration issues kept me from joining them, but I think (?) that a New Zealander wouldn't have that problem.

"However, we have this new "web" platform,"

You know... We have had this new open-source platform that created lots of programs that can run on anything. I use Firefox on Windows PCs (it's not my fault - company policy), on Linux PCs, on a PPC Mac (and an IBM) and under Solaris on a SPARC box. It works well (apart from Flash support) on all of them.

BTW, all these boxes have GNU command-line tools and a decent set of compilers and interpreters (I run Cygwin on Windows). With the exception of Windows and Mac, which impose their looks on users, I would be unable to tell what I am running under the GUI from a screenshot (not really - the AIX box runs CDE).
I'm a Windows guy and we use OneNote. I suspect EverNote would be a good option too.

Science fiction is largely about telling one story while pretending to tell another.

In the case of Avatar, it's a couple stories as old as man (and perhaps older) - use of violence and cohesion of the powerful against the weak, impossible love, hero warrior enlightened and betraying his original allegiances and religious experiences are just the few that pop up after 2 minutes of thinking about it.

And, of course, you get a big reaction when the audience perceives it as telling their story while pretending to be about blue aboriginals of an alien moon.
Yes, it comes from the Latin. So maybe this is not a coincidence, since Julius Caesar invented the ROT13 cipher.
If you get to the frontpage of HN, then about 8 services willl link to it automatically on twitter. If your content is good, it will get retweeted, someone will post it on reddit and so on.

The core point lies in your content - you can't force people to like shit they don't like.
I'm afraid patents are too strong for that. It's illegal to infringe on patents even for your own use.
FWIW: SCEA provide an implementation of OpenGL for PS3 so it should be 'easier'. I've heard it's not that fast given the strange nature of the PS3 hardware pipeline but it might be fast enough.

Ironic that his follow up post about just being 'you' also just happened to pander to the HN crowd which as a result will probably bring him another 25K plus in traffic?

Simply writing and waiting for the traffic to roll in is unrealistic. You can still author great content and promote it via social/news/blog platforms. Just because you market yourself well doesn't make your content crap.
It may not seem like a revolution but I think the micro loan model is a huge revolution. Not just because it lifts people from poverty and empowers.

One of the most important things it does is show people in rich countries that poor people are both hard working and honest and are not in need of charity but are in need of help.

We've been stuck in a cycle of giving charity to poor countries and nothing seems to be getting better. MLs have helped to break that cycle and empower ordinary people (not warlords, clerics or politicians).

So I think that's an innovation :)

No, that's not true. DirectDraw was deprecated with no replacement, then Direct2D was created for Windows 7/Win2k8R2.
maybe there's more than one task, but the task i took appeared to be completely specified (the one where you find a balance point - i may have remembered the name wrong - for an array, so that the sum of elements to either side is equal).

it wasn't obvious to me what to do on first read, but when i paid a little more attention, everything was there (including edge cases, as far as i could see). in particular, they gave a formal numerical expression that was unambiguous (and which didn't seem to contradict the text).

I have a personal policy of always downvoting such comments when I see them, (1) to reduce the distortion caused by the effect you mentioned and (2) in the hope of slightly discouraging them.
It's a sad comment on our society that such an utterly ludicrous notion ever even raised its ugly head.

To add to this point, Avatar is actually more than an old story: it's a boilerplate movie plot. Anyone who is educated about script writing knew exactly what it was by minute 20 because it followed the formula to a T.

The reason the formula exists is that it's versatile. Anyone can plant themselves inside and understand it from their worldview. That's why it's so similar to other movies, and that's why people can see the Vietnam war and Chinese real estate developers in it.
thanks. another smaller point i just remembered - i was a bit surprised to see that the evaluator could see my submissions to the "validate" function. given that you do say they won't influence the score i assumed that they would be discarded.

i can see there are several reasons why this is useful to the evaluator, and i can also see that you're getting close to saturating the user with instructions, but in a perfect world it would be good to have "full disclosure" (i guess you do, in that anyone can run the example....)
I got this far:

If someone buys an exception to embed a program in a larger proprietary program, he's doing something wrong (namely, making proprietary software). Does it follow that the developer that sold the exception is doing something wrong too?

Then shrugged and kinda gave up. :) Initially some great points were made but after that paragraph it seemed to turn more into a postulation that GNU GPL was more ethical (his words) than other licenses.

This suggests a fun interview problem:

The title is rather misleading (not the submitter's fault -- it's the title of the original post). It's not "array comparison that's independent of timing", whatever that might have meant, it's "array comparison whose timing is independent of the contents of they arrays". (To avoid side-channel attacks on your crypto.)

I think there's an oversimplification in the first section, though it may be a deliberate one for the sake of clarity. Your goal isn't really to know each byte with 95% confidence, it's to know enough about the bits that you can do a small search and be likely to find the right key / hash / whatever. Which means that what you really want to do is to have a model of how the timings (noise and all) relate to the actual values, and keep going until the total entropy of the secret you're trying to extract gets small enough.
Hello, VM is already in alpha on Git actually. There is some more work to do, but I don't think in the Reddit use case there is the need of Redis VM: they are using MemcacheDB as a persistent cache, if it's a cache it should match very high performances delivered by memcached and is not required to cache everything. Redis is as fast or faster than memcached (using clients with the same performances) and is persistent, so probably it's a good fit for this problem.

Instead of VM Reddit should use Redis EXPIRE I guess, that is, time to live in cached keys so they auto expire.

Btw for people that don't know what Redis Virtual Memory is: with VM Redis is able to swap out rarely used keys in disk. This makes a lot of sense when using Redis as a DB. When using Redis as a cache, the way to go is EXPIRE: rarely used things in cache should simply go away and be expired instead of being moved into disk.

EDIT: It would be very interesting to know where the Reddit performance problem is, but Redis Sorted Sets are a very good match to create social-news alike sites like HN or Reddit in a scalable distributed way, with a few workers processing recent news to update their score into the sorted set. The home page can be generated with ZREVRANGE without any computation.

It's a shame reddit is not sharing how this cache is used.

"If I'm reading your blog, it's because I want to hear what you have to say, not because I want to be pandered to."

Claiming authenticity and claiming you have no underlying motive are powerful mainstream marketing techniques. I doubt the motivations of this author are any different than the motivations of the other author that admitted he was trying to manipulate us. This author is just taking advantage of our gullibility whereas the other author was pointing it out. Nobody likes to hear they've been manipulated, but which is really the more valuable message?

There's a reason why TV commercials don't start out with "The purpose of this commercial is to manipulate you into buying this product."

The pictures are only illegal if they are deemed indecent by a jury - a picture of a naked child is not of itself indecent unless they think it is. However, the public view of indecency has changed greatly though, "thanks" to media campaigns, so there's a real risk that such pictures could be deemed indecent.
I haven't linked the page anywhere but here yet. I trust this community as a reasonable gauge of how people will react, and wanted to know whether or not you think people will have enough interest to make this happen.

Yeah, that demo problem would probably take me at least several hours to solve. I'm bad with sequences and I have a volatile short term memory which means I make mistakes and am slow to process numbers and logic. Interestingly these flaws cause me abhor any over complex logic or code where you have to remember more than 4 or 5 things at once to use properly, which makes my code clean. So maybe I'm not a good programmer (I can't write the complex stuff very easily) but the code I write is usually good. Try testing for that Codility!

BTW 10-20% of the population is like me.
