as others have said, first thing to do is plot the data. but if you want a statistical test (with significances, so that you have some idea of how confident you can be in your decision) then you could use the two-sample ks test. it's likely more useful that a simple t-test here because it's sensitive to shape.

but to be honest the first thing i would do is google for suitable approaches...
Its a bad idea because it propagates class ordering on the basis of knowledge.
The Era of Gamification
I have to admit that the first time I got really aware of Bletchley Park was while I was reading Cryptonomicon from Stephenson and started looking into its actual history. One of the few monuments in reality the digital age actually has. Nice to see it preserved.
Poker MTT Principles
Actually I think the fundamental problem is simpler :
* 90% (or something like that) of people are employed by huge companies that are basically dependant for their future existence (and profits) on barriers to entry in that market. Whether we're talking banks, chains, marks, and software firms ... that's a hell of a lot of people.
* we're 10%. At best.

And we live in a democracy. BTW: if it is indeed true that these companies depend on excluding others (which is of course not 100% sure) it would be a REALLY bad idea to replace those companies by other more efficient companies, if those new entrants are more efficient due to less personnel (which is nearly always the case)
I second that.
Started convict conditioning a month ago and I don't have a rigid schedule for training. But I will train every other day regardless of what happens on that day. This can mean I will do it at midnight but usually I do it earlier taking a break from work. It is a great way to channel procrastination into something useful.

No. I'm sorry, but once you go 329ppi, 218ppi is embarrassing; compare the /size/ of the screen all you want, but all it means is that the contents is that much more pixelated.

Now, the Samsung Galaxy S II LTE HD (which has a 316ppi screen) is competitive, but the Galaxy S II is no comparison: you want an iPhone 4. Trust me: I don't like Apple winning this; I hate their attitude on openness more than just about anyone else, and I'd love a more reasonable piece of hardware to rest my software on, but they leapfrogged the competition so hard on the things that actually matter for day-to-day usage of the device, that apparently a year later other vendors aren't even trying.
Sure you can. My hands are pretty small and i can basically use it for simple things like reading an ebook, flipping the pages, read a new sms, call someone etc.

The title promises much but the article lists well-known applications. I'm unsure where the increase in productivity comes from.
What Does Your Resume Font Say About You?
A big advantage to this is for applications that require HIPAA compliance. One of the rules for HIPAA is to encrypt data at rest. There may be better ways to encrypt your information, but this will tick a box for compliance purposes (the advantage of this shouldn't be underestimated).

It basically allows HIPAA abiding applications to use S3 for data storage without the complexity of dealing with the encryption themselves, or using a 3rd party provider that offers this by proxy.

The only remaining step is to trial and error your way through using it due to the "light" documentation.
https://github.com/glenjamin/node-fib is close enough. Trying to explain how Node can do concurrent Fibonacci without calling another process is falling for the troll's trap - Node isn't "the one true tool", and you don't need to try to prove that it is. The trolls will just say that Fibonacci is too trivial, and you wouldn't use the same approach (co-operative multi-threading) for less trivial CPU-bound tasks.

You can use a hammer to bang in screws, but it's not usually the best way. If you are using co-operative multi-threading as a way to get Node to handle concurrent CPU-bound requests, you are Doing It Wrong (TM). In general, it's better to create a second (possibly not async) server to handle CPU intensive stuff, or fork stuff off to a subprocess (depending on the actual task). There might also be other ways - I'm not an expert.

I'm sure that if glenjamin had a less trivial CPU-bound task, he/she would handle it a better way (depending on what the task was). But to the Node haters, node-fib is just troll food. It's also an interesting example of how node.js works, but the trolls don't care.

Blogspot security hole lets others view unpublished blog entries
Does the thread starter wonder about what software tool (i.e. language) people would use, or does he wonder about what method people would use? As far as language goes, the problem requires mathematics on a level so simple that practically any programming language is more than enough sufficient - the histographical method I'd use for solving this problem would be doable in BASIC on a VIC-20 or a TI-81 pocket calculator.
Apple Releases iOS 5 GM To Developers
But there is 'progress'. Looking at the Wikipedia page:

"The proof of the conjecture can indirectly be done by proving the following:

- no infinite divergent trajectory occurs

- no cycle occurs

thus all numbers have a trajectory down to 1.

In 1977, R. Steiner, and in 2000 and 2002, J. Simons and B. de Weger (based on Steiner's work), proved the nonexistence of certain types of cycles."

I am placing 'progress' in quotes because one cannot measure progress in maths. Before one has a proof, we cannot know whether existing approaches are true dead ends or whether they just need that one extra insight.

The article says that not everyone got the joke:

"More surprisingly, Cow Clicker developed an active player base–-people who missed the humor and attached to it as if it were a "real" game. These players unquestioningly spent real-money Facebook credits to enjoy their cows and sent Bogost innocent player feedback in the hopes of improving their experience.

It subverted every expectation that he had, even as it reaffirmed his worst fears about the exploitive sadism of Facebook game design. Its success also became something to dread. A Slow Year represented everything Bogost loved about games; Cow Clicker was about everything he hated."

From the programming I have done, I would say most of the 'repeated' functionality is things you would have done already, just in different ways. In fact, things like making the while loop a for loop is taking away things you don't really 'need'.

It is quite different when compared to python, but it is probably better compared to C, C++ or even Java. C is nearly 40 years old, a lot of the decisions that were made in its creation look silly now (terminating strings with '\0'? yeah, great choice). From what I can see of Go, they try to address many of these aging conventions.

+1 on the cloud advantage.

I tried Google Voice Actions on my Nexus One quite a while ago, but it was optimised for the US market. The accuracy for me was so bad that I didn't bother with it.

Then recently, a Google blog on RSS said the latest app had been optimised for my locale. Now, of course, it's spookily accurate.

You can't beat your algorithms in the cloud being bombarded with sample data round the clock.
I would use one of these two tools:

Orange http://orange.biolab.si/
"Open source data visualization and analysis for novice and experts. Data mining through visual programming or Python scripting. Components for machine learning. Extensions for bioinformatics and text mining. Packed with features for data analytics."

Weka http://www.cs.waikato.ac.nz/ml/weka/
"Weka is a collection of machine learning algorithms for data mining tasks. The algorithms can either be applied directly to a dataset or called from your own Java code. Weka contains tools for data pre-processing, classification, regression, clustering, association rules, and visualization. It is also well-suited for developing new machine learning schemes."
Another strategy you could try is to figure out why people like your App 1 (game?). You'd have to build in some sort of stat collection. Then you can try to replicate that in your later apps.

For example, if you look at games published by Donut games they all have the same basic structure. A bunch of puzzle levels on a 3 star rating system, and you have points assigned to you as you finish the level in the optimal fashion. The game itself is different every time but most of the time you're picking up a point object as you traverse the level, or you're traversing something in the shortest path. Whatever it is about these games, my girlfriend has downloaded almost all of them. You could try to go for the same effect.

This Wikipedia page covers the history of Enigma cryptanalysis well: http://en.wikipedia.org/wiki/Cryptanalysis_of_the_Enigma

Bletchley Park fully recognizes the significance of the initial work done in Poland (see, for example, their annual Polish festival: http://www.bletchleypark.co.uk/calendar/event_detail.rhtm?re... and publications like this: http://www.bletchleypark.co.uk/content/hist/history/polish.r... and the Polish memorial on site).
The reality is that with the current financing environment, there will be a ton of "orphaned startups". So if you're startup that raised an angel round of $500k but will need to raise a real Series A down the road from VCs, you may have a tougher time unless of course you are a breakout success (translation: outlier). And with Series A being tougher to raise, that startup will die die or sputter along for a while. Of course, if you can become revenue generating and a real biz, you may be able to live to fight another day.

Angels, unfortunately, cannot bridge this gap as they can't write the bigger checks of a Series A, B, etc round. So while there may continue to be seed/super early stage money to start up, it's the follow-ons which will become more difficult. This, of course, may just be natural selection at work and a good thing.

Also, while the article talks more about VC, if the stock market falls and uncertainty grows, angel investors will also pull back. Of course, there will be some who will not, but for many, their wealth goes up and down every day with the markets. And if they are feeling less wealthy, their willingness to invest in startups (the new status symbol for many) will also decline.

Maybe the way you worded that is a little harsh: I think that's a fine goal but when you approach an employer you might want to put that goal in the context of the company you're interviewing with. So in effect, you want to use your career goals as an angle by which you might sell yourself to the prospective company.
I wonder how piwik or browsershots could make me more productive.
People that I know and which have bought the iPhone 4, did this because of the design and because of the display. Among them are people using their iPhone just for phoning and SMS - some of them do not even know that there is an AppStore and that they could download applications ;) And I must say that half of them have now another phone. And 5 of them have broken and replaced already once their display.

So it is not only about software - design plays a huge role.

I used a spreadsheet to calculate the standard deviations. A,D and E have twice the deviation of B,C and F. (10 vs 5)

The means are all the same.
I suspect those numbers have nothing to do with the cost of the system creating a thread or a process, but instead are artifacts of how Python handles threads.

When Python forks a process using the multiprocess module, that process can execute concurrently with the parent process. On a mutlicore machine, it can be simultaneous.

When Python spawns a thread, the thread and the parent process cannot execute concurrently. They need to grab the Global Interpreter Lock (GIL). Whoever has it can execute. Whoever does not must wait.

So, I suspect that what we are seeing is that even though the new processes/threads have very little work, the processes can exit faster because they don't have to wait for the parent process to give up the GIL. This is a misguided experiment.

I would use my right hand to slap Alison and Charlie and get them to do their work again... this time forcing them to label their samples.

I would then take them into my office and hold an inquest on how two completely different data-sets got mixed up in the first place.

At which point I would probably find out Alison and Charlie have been knocking boots on company time.. Alison and Charlie would then be fired as this is against company policy.

Due to the difficulty in finding new jobs Alison and Charlie's fledgling romance would end... leaving Alison unexpectedly pregnant and Charlie with an 18 year bill for child support.
