So what's the narrative for consultants who preach the value of A/B testing everything? :)
Setting aside the riots, the prevalence of BBM amongst teenagers is a really astonishing phenomenon. Blackberry is the smartphone brand amongst British teenagers and if a peer group has "gone BBM" the network effects mean that no other brand is even worth contemplating. In the UK at least, RIM have practically given up on the corporate market and BlackBerry is increasingly seen solely as a youth brand. BBM is so deeply entrenched that there's a palpable backlash[1].

I'd love to see some research done on the ethnography of it all. The common argument is that BBM is a very cheap way of keeping in touch - unlimited data is £5 a month even on a prepaid tariff - but I'm not sure how well that argument holds up. Unlimited SMS has been that cheap for years and there are plenty of other options.

I think the real reason is more sophisticated. I think (but can't prove) that many of the enterprise features in BBM are hugely valuable to young people. Ubiquitous, instant delivery and read receipts are helpful for corporate users, but they're vital if you're a teenager who has just asked someone out on a date. The simple but highly nuanced implementation of message groups was clearly intended to allow easy and ad-hoc communication for business groups, but allows teenagers the fine-grained control they demand over their social circles.

In many ways, what Google are trying to achieve with Circles in Google+ has been achieved by teenagers using BBM. I think in many ways BBM is as important as Twitter, but entirely invisible to the outside world. I think we have a huge amount to learn from the runaway success of Blackberry amongst the youth.

I tried a ~22" screen vertical for a while, primarily for coding, for exactly the same arguments you made. I switched back because I found I was still only using about as much of the screen as I was when it was vertical - I'm much better about looking side to side than I am up and down - and because I'd rather have two or three windows open side-by-side than one on top and one on bottom.
Maybe it is a thought experiment, but what we see from Brian's story is that this thought process can be taken outside of the tech/HN/twitter bubble we all live in. It might kind of be enlightening to try this out in the real world (buy a coffee with cash for a stranger) then come back and share your experience.

There are so many little things you can do that can make someone else's day. Here's another one: cook a meal for any new parents you may happen to know. Nothing fancy, just something you can drop off that they can easily reheat and maybe lasts a couple days.
Modern operating systems can handle this correctly I believe.

Funny you should say Fox News, because the 30-40% number was pulled out of thin air by a random TechCrunch writer with absolutely no sources or evidence. I've yet to see a single factual report showing Android's numbers being any higher than average for tech devices.

But sure, go ahead thinking that iOS is a radical change.
I know nothing about the technical details of font rendering algorithms, but isn't that just an implementation detail? How hard would it be to write a font rendering algorithm that works when each RGB triplet is a vertical line? And having done that how hard would it be to implement a font renderer that switches between the two algorithms depending on screen orientation?
in another thread thucydides says:

Note that each act separately is fine: you can demand money; you can threaten to report a crime. You just can't make the report conditional on receiving money.

So in essence, you're saying that we're both right.
I don't get why these libparted features were "deprecated" when their removal leads to GParted 0.9.0 effectively dropping FAT16/FAT32 and HFS(+) support.
Absolutely, authentication is not bullet-proof. That's why certificate authorities have to invalidate certificates from time-to-time.
There was a separate article a couple weeks back that talked about how mobile apps shouldn't use TCP/IP since its linear and mobile has a tendency to do crazy things like switch towers. Sounds like SPDY would be much more useful as a defacto mobile protocol.
I have to say I don't really like their new tutorial video. But the handful of comic style images they had before was great. Simple, clear (and also funny).

If you tax it much, there will still be a black market for it, with all the associated crime that brings.

And it's a lot harder to differentiate illegal goods from legal ones if the physical item could be either.

I'm not saying whether we should or shouldn't legalize it, but I keep hearing people say "legalize it to remove the criminal element and tax the heck out of it." That doesn't necessarily end the associated crime issues.

How algorithms shape our world
The real question - is it necessary, or even a good idea, to vertically integrate teaching and assessment? Maybe for a specific area of string theory, where both teachers and assessors are thin on the ground. But for calculus 101?
No amount of bit-bashing can fix really poor choices of algorithms (N^2 vs NlogN, say, on a big input).

Its also worth noting that sometimes an algorithm with higher O() complexity could actually perform better. Eg, a brute-force linear search may be faster than a binary search if the elements can be efficiently cache prefetched, or if the entire dataset fits into cache.

I personally don't see the advantage of using other hardware, Apple hardware is a better value to me. (I value reliability over lower initial price, and I don't find generic PC components to be cheaper for the same thing, nor to have adequate reliability. )

It looks like the same support for all file systems was removed from libparted. According to the release notes:

Changes in behavior

Remove all FS-related (file system-related) sub-commands; these commands
are no longer recognized because they were all dependent on parted "knowing"
too much about file system: mkpartfs, mkfs, cp, move, check, resize.
This change removes not just the user interface bits, but also the
library functions and nearly all of the underlying FS-munging code.
The code embedded in Parted by which it knew about those file systems
was so old, unmaintainable and buggy that while seemingly drastic,
this change is like removing a gangrenous toe.

Isn't the issue really more about the quality of the light, which can't be captured in photos? CFLs give me headaches after a while, just like big florescent office-style lights.
That's actually a valid point with A/B and MV testing - you can get stuck on local maxima. It's why the process still requires manual intervention and design skills. Most flaws with A/B implementations are people/process or misuse.
$40, though, really?
I guess what's missing is any indication that libparted does not intend to reimplement these features in the future in another manner? I mean it reads to me that gparted is announcing the ability to even use libparted-3.0. I mean there's a reason the libparted people bumped the version number to 3.0 (i.e. freedom to re-design the API), you know.

Well ok, technically the job category (smartphone app developer) existed, but it was insignificant compared to how important the role has become. Apple basically showed everyone else how to do it[1]. I've read that trying to launch an app on a platform like Symbian in the "old" days was an utter nightmare. You would have to deal with carriers and try to convince them to approve your app in some cases.

iPhone development was my first "proper" job after finishing a masters degree. I'm not currently making money from iOS apps, although I hope to once I gain a better understanding of iOS development. The company I work for is doing some pretty cool stuff with apps, I hope to be able to talk about a project we've going on here on HN in a few months.

I hear what you're saying about net zero gain from a few technology displacing old jobs. I think that's just a short-term phenomenon. If apps displace some jobs in more traditional industries (e.g. the apps in my company aim to replace paper-based product catalogs with iOS/Android apps that do the same thing, except faster, better, cheaper) then I think:

a) more jobs will be created in the app development space

b) the productivity gains, cost savings and perhaps new market opportunities offered by apps will allow the beneficiary company to become more profitable, leading to job growth in that company. This has a knock-on effect also for those who deal with the beneficiary company (e.g. suppliers getting more business, customers getting better prices, better service etc.)

I believe a and b will lead to net jobs gain in the longer term, rather than jobs lost overall by the printing company and related companies.

[1] They stumbled on the model of an app store by accident. Steve Jobs thought that all iPhone apps would be web-based rather than native apps when the iPhone launched in 2007. Luckily, Apple was smart enough to recognise the opportunity, creating a river of cash for Apple.
Well, that might be true or not. It is just another topic. Just because there is Android in the header doesn't mean all Android topics are equally important in this discussion.
This sounds interesting. I use Chrome. Does somebody know if there is a similar feature there?
Why is your app's squeeze page so big? It's over 3MB, mostly being weighed down by a 2.46MB background image (because it's a photo and you used PNG, you could cut it down by an order of magnitude by using JPEG). I'm glad I wasn't on 3G...

What Happens When a Reasonable Developer Runs Into Aggressive Trademark Lawyers
A timing loop will tell you how fast it runs on your particular configuration, but not how fast you can expect it to run in the general case. For that, you need to get very intimate with the processor manuals, especially optimization guides. Also, a good profiler, like Intels VTune, is great for getting low level performance data such as cache misses.

Also, doing what you suggest on a number of combinations of hardware would be useful, so you can compare various processor architectures.
Yeah, I was being sarcastic. I get irked when gender roles sneak their way into things like this.

Aspose.Tasks is a non-graphical .NET Project management component that enables .NET applications to read, write and manage Project documents without utilizing Microsoft Project. With Aspose.Tasks you can read and change tasks, recurring tasks, resources, resource assignments, relations and calendars. Aspose.Tasks is a very mature product that offers stability and flexibility. As with all of the Aspose file management components, Aspose.Tasks works well with both WinForm and WebForm applications.
Is it just me, or are the examples in the middle using 'md' and 'fr' wrong?

If they're not wrong, why are they so bloody confusing?

Edit: It's been fixed now. The final example had 2md, 1fr, 1md originally, instead of the 3md, 1fr, 2md that it has now.

That is a little sad because the FS code was once the whole point of Parted. But that does not mean the removal was not justified, I don't know, I've been away from Parted for a very long time.

In portrait mode, I tend to center whatever I'm looking at, but having a wide vertical aperture still makes it a lot easier to navigate a large document. Though it's annoying when I'm reading the bottom of the document and can't center it.
I'm not saying the yellow-highlighter crowd is wrong, not at all. But would YOU buy from them?

Your question exposes a really important fact about split-testing:

People are complex. Different stuff works for different people.

The yellow highlighter thing tends to make people like us wanna hurl… it triggers immediate distrust. Meanwhile, information marketers still find that it works.

You can't know who a person is when you split-test against them.

More importantly, you need a LOT of traffic, and even minor temporary changes in traffic composition can affect the quality of your data.

You will see that traffic from HN responds to & converts very differently than traffic from Lifehacker, and again different from Small Biz Trends. Initially you may find certain changes increase your conversion rates… and two months later you find you have lost almost all those customers, or that a disproportionate amount of them have asked for refunds, or been shitty to you in the support channels. Net result: a loss, which you only found out about months after you were so confident that your testing showed a gain. Would the other half of the split test do better? You can never know, because you cannot replicate the exact scenario ever again.

Traffic is not created equal; traffic is made up of different individuals. You can only ever get a feeling of what works for some of them some of the time, depending on several factors.

Take the yellow-highlighter example again: Why does it work for infomarketers when it makes people like us flee in the other direction? They sell to different people. Why would the Hacker News crowd be worse customers than the Lifehacker crowd? Because they are different types of people.

Unless you run a months-long test covering all parts of your business (refunds, avg turnover rate, length of customer stay, # of support inquiries/nastiness in support inquiries, resource usage, server bills, etc), tho, split-testing can't tell you which types of people are better for you.

And if you DO do that, when exactly will you have time left to expand and market your product?

I'm not saying split-testing is wrong or useless, but people use it to try to create scientific certainty when it's absolutely NOT possible to do so.

I think this is plain silly. The article does not provide any proof besides telling us how BBM could have possibly be used in such cases. Did you really catch people who planned it using BBM ?

Showing couple of BBM results from twitter is a clear case of ignoring the elephant in the room (twitter itself) and going after a fly.

This is probably possible through some extensions and Firefox. The much loved TreeStyleTabs already has an option for "autohide the tab bar". If Pentadactyl/Vimperator don't already have an option for autohiding, it's probably pretty easy to script something up.

Yep. The things they do are not that great to allow for his tone. "Kovodstvo" was a good read for me when I was starting my proffesional career as webdev (around 1999), but I left it for the higher quality in English (and because Lebedev's studio still cannot code HTML).

The average lifespan in the US is decreasing.

Most importantly we spend twice as much of our GDP on heathcare as most contires with universal heathcare for reduced benifits. If the numbers keep getting worse the government can get involved in the supply side of the equation without reducing benifits to patents.
The code was removed because it was old, bitrotted and potentially dangerous. You really don't want to use old unmaintained code to resize your precious filesystem data.

In any case there are better ways to do this. I have an interest in this, having developed libguestfs[1] and virt-resize[2]. But I'd say that even if you don't use libguestfs, you must use the latest upstream kernel code and tools (as libguestfs does) because that's the code that will not corrupt your data.

I think it's more - sometimes you want to, sometimes you don't want to pay for a cup of coffee. Though, I don't think the experiment is to see if people are willing to give coffee to those who can't pay for it.

It's an experiment on social contribution, if I'm correct. Even though you can leech (and some will), a good amount of people might ultimately add more money than they spend from it. But why? Everyone is anonymous (kind of), and it's not like you have external pressure to be good.

If the amount on the card stays positive, you may have renewed my faith in at least a portion of mankind, Jonathan Stark.
Ah, but that's just dividing the area of stories vertically and picking one, it will just keep the SNR constant by including the bad articles in that specific topic along with the good. What I'm trying to do is cover everything, but exclude the noise...
I am the parted maintainer for Fedora. I also help with upstream a bit (I removed the CHS asserts for example). These are my own opinions:

These 'features' were removed because they were old, not well maintained, and don't fit into the core feature set of parted. You are better off relying on dedicated tools to do your filesystem specific operations.

I don't get it. Is a single huge browser window seriously considered "good" now? I thought that the whole point of the "useless" green button in Mac OS X was that you should never maximize anything. Two browser windows side-by-side are much more useful than one of twice the size. Are we really moving away from multitasking on the desktop?
Exactly -- teaching and grading should be separated. I'd prefer a smart AI over some random remote assessor any day.
