The most popular computers and electronics in the world are Apple products because Apple polished everything to a sheen.

Sure apple created some cool stuff, but the open source world created some pretty darn cool stuff too. Remember, the first web browser was open source.

That's really not the case.

That's part of it, but there were also huge quantities of marketing and money involved.

Honestly, I don't think the reviewer saw or used the Tablet. This is more of a collection of data from sources.

I'd really wish this becomes true and Indian students have access to something cheap and affordable. At that advertised cost, I'd say it's perfectly OK to have rough edges.
Really? Care to give an example on the second one? Sounds like a lot of hand-waving to me.

Obviously, if no one finds out about what you did, no one will know about you. If you're doing something truly extraordinary an old diary, some notes in the margin, or just visible side-effects are enough.

This kind of over-simplification doesn't say much at all. If you're finding the cure for death people will find out eventually, and if you're someone who accidentally got famous (catastrophe survivors, some TV-personalities) you don't have to do anything to get lucky.

EDIT: Replace cure for death with say - trading strategy that makes you insanely rich, or some software which helps you do x much faster than anyone else, or anything really which carries the original signal forward. It was just an extreme (and silly) illustrative example.
The only interesting thing here is that the author has found similar tablets with comparable or even better specs for similar or even better prices.

The issue is that virtualbox is crashing the host kernel, not the guest machines. And specifically that it's polluting Red Hat's automated bug reports from those crashes, and thus wasting QA effort. Being able to filter those out by the taint mechanism in the patch is important and useful information. Read the thread, it's a technical and process discussion, not a flame.

This is probably also based on user study data. I actually took part in a user study where we had to play with about 10 different phone and tablet sized lucite rectangles. They all had numbered grids and you had to hold it different ways and say how far up/down/over you could reach.

You also had to note your thoughts on holding, storing in pockets, etc.

Afterwards we had an open discussion period and most people seemed to agree that the iphone size was close to best, but that perhaps the screen should take up more of the real-estate, like how it does on the droid.
Amazon Links to Competitor (Apple) Off Its Front Page
I've been avoiding most of the Jobs coverage, because while he was a brilliant man, some of it feels to me like self-promotion by those who are seeking to increase their own media profile on the coattails of a legend.

BUT, this simple link off Amazon's front page was HUGE to me. No long eulogy, no "My thoughts on Steve" commentary.

Just a DIRECT LINK to a COMPETITOR's site, at the same vertical position as the product link for their own Fire tablet. That's sportsmanship and respect at its' best.

kvm, for one. Not quite as featureful, and the UI is a command line (though there's the virt manager stuff that I haven't tried). But it's rock solid virtualization that never gives me problems.

I think people are misunderstanding this thread. This is a kernel developers thread, where Dave Jones is complaining that virtualbox is the source of too much random corruption and arbitrary crashes in the kernel, and he's submitting a patch that "taints" the module such the presence of virtualbox gets flagged in kernel panics (and thus automated bug reports, etc..).

It's unstable software, and that taint is important information that prevents people from wasting effort chasing non-bugs in other components. No one is flaming about it vs. vmware or whatever, or telling you what to use.
Software is only obsoleted by some other software getting adopted in its place. How well adopted a piece of software is is only vaguely related to how innovative it is, how technically sound it is, etc.

I've got both one-liners books (Sed and Awk). Peteris takes a very practical approach in the book. I almost think of it like a field guide. Think of the times you've google searched for something like 'number lines in file sed'. These books not only provide solutions, but give detailed explanations of what's happening. Pick any given example and there's a good chance you'll gain some insight about how sed/awk work. They're very well written, and very accessible.

Having said that, if you're a long beard who has long been acquainted with these tools, you could maybe skip them.
We can't unequivocally say it's not racial profiling. All we know from the article is that ethnicity is being used as a factor. If a person's race/ethnicity can in any way make it more likely for the system to flag that person, then racial profiling is arguably happening.

So the question is: Under this system, can a person's race increase the likelihood of a positive result? It seems the answer is yes. If race is a factor, that means it's somehow being used as in input into the algorithm that determines a person's suspicion score. Maybe it's not something as heavy handed as "boost the suspicion score if the person is of race X." Suppose it's "weigh eye movement more heavily than breathing if the person is of race X." Even then, the effect is to increase the likelihood of a positive result _for some people_ based on their race.
I would suggest that minor PHP versions often are, too. Significant internal changes between 5.x versions have caused some code to break (and other code to act very differently than it was originally intended to).
I thought everybody had to use Metro starting with Windows 8.
What would happen to something like this, if it starts getting a lot of false positives. Considering it's breathing and heart rate, could we not easily make it give out false positives? I mean it would probably inconvenience us, as an individual, but after a few months of tons of false positives, would they not abort it?

>Why is having a free program that solves a problem that's already solved more important than creating programs that solve new problems, but that also happen to be free?

Because their goals include that everything possible should be possible for to do with free software. It is by definition a game of catch-up.

But that's one of the major benefits of free software. The software that makes today's software obsolete will be able to do everything that today's software can do, and more.

Sometimes that's through new paradigms, but more often that's through incremental evolution.

His problem is not with functional programming (i.e. avoiding state mutations). It is that he tries to do inductive definitions and functors in a language whose syntax is extremely unsupportive. In OCaml that would be (untested code):

> What's interesting is that the electrons got exited but the nuclei did not.

This statement can't be right. If the temperature of the material went up, then the nuclei became exited. And if they didn't, then the result is identical to the photoelectric effect.

Edit: By the way, what you've described corresponds to "freeze-out" in old-fashioned semiconductor terms. As you drop the temperature of a diode, the free electrons and holes fall back to their low energy state and it turns back into a vanilla semiconductor. Heating it up makes them mobile again.

Yeah, it was clear that the PR was not written by someone knowledgeable. I'm sure there are MIT folks on this board so I'm hoping one of them pokes the right colleague so that we get a clearer answer, because it sure sounds like there's something interesting going on there.

Thanks for the arxiv pointer, I'll try to look this weekend.
Direct quote from the article:

The free software approach seems to assume that what a computer should be and do has already been decided and they just need to make free versions of everything.

When you you look at their goals, they are by definition playing catch-up. You're also glossing over every single innovation that has come out of the open-source space.

The most popular computers and electronics in the world aren't Apple products because Apple made an Apple version of everything.

Actually, the fact their operating system is just an Apple version of unix is the primary reason I even considered purchasing my mac. The same rings true for most of the technical people I know who have macs.

Well I'm not sure what kind of PDA you were using then, but all the Palm, Handspring and various Linux ones (can't remember what they were called) that I used worked only with a finger when you used your nail, and even then there was no telling what exact 'touch point' the screen/OS was going to use.

It's much like today's TomTom devices. They are advertised as being 'touchscreen', and the UI is designed as such (with big buttons etc) but they're still a bitch to operate. I mistype at least 20% of my interactions with it, and like I mentioned I have a decade of experience with working around finicky touchscreen technology (as much as I hate to admit).

I'm not saying you or anyone else wasn't able to operate a previous-generation touch screen with their finger, but the experience simply wasn't good enough to make it mainstream. For example an on-screen keyboard is/was out of the question on a Palm.

Wasn't even aware Romku existed. What a cool service. I personally think, though, that the spreadsheet is more useful, just because I can compare features without having to click on multiple choices and looking at each individual list of features. However, the spreadsheet can indeed become unwieldy. Might be more useful as separate spreadsheets for each category if it gets too large.

> The diversity of screen sizes and browsers and DPIs is greater than it has ever been, and will only increase.

That may be true, but beyond a certain point, it doesn't matter.

In terms of physical size, it makes sense to have a single-column layout for small devices, where layout techniques like using multiple columns are never going to be very useful no matter how high the resolution gets. You might prioritise some content more highly and reduce or eliminate less valuable material to go with this. It also makes sense to allow for layouts that do have wider areas and/or multiple columns if the content can benefit and the display medium can support it. I doubt anyone is going to want to render most web pages with dozens of columns any time soon, though, no matter what physical size a screen might reach. Most content isn't going to benefit from that, because the human eye and brain can only take in so much at once anyway. So the big question here is how many discrete layouts are useful in practice, with a whole load of secondary questions about the balance between showing more content at once vs. allowing user interaction to navigate content in different ways.

In terms of resolution, the consideration is different, but there is still a general case. At low resolutions, it is worth having specific, pixel-perfect designs. At somewhat higher resolutions, it is worth having different pixel-perfect designs, to give sharper results at a similar physical size. Sometimes it is best if pixel-based designs don't try to copy all the detail of the "true" designs as they get smaller, but present simpler, cleaner versions of the same basic idea instead. At some point, your resolution gets high enough that scaling vectors representing the "true" designs by default and using techniques like antialiasing and font hinting becomes a viable alternative. Somewhere beyond that, vectors alone would be sufficient, as the eye isn't powerful enough to see any more detail anyway. The big questions are where on this scale you change from one pixel-perfect format to another, and how many such formats you produce before you switch to using scalable vectors.

In the real world, of course, these two ideas interact at times, and there is a cost/benefit trade-off as well. Perhaps you would prefer to have three sizes of pixel-perfect versions of all your custom graphics plus a vector, but in reality you might have only one or two and accept that content will appear at significantly different physical sizes on different devices. Perhaps you would like to have a responsive design with four different layouts, but in reality a mobile-friendly version and a regular site will do. You'll still be able to cater well to many different devices with only a small number of combinations if they are well thought-out, though.

I wouldn't recommend it if you want to get something done. It is an interesting way to explore the set of features they have chosen for the language(Prototype based OO, meassage passing, code easily modifiable at runtime). The point of the language seems to be more art than tool:

Io's purpose is to refocus attention on expressiveness by exploring higher level dynamic programming features with greater levels of runtime flexibility and simplified programming syntax and semantics.
