Micro controllers are simpler you can start with Arduino, easy to buy also books, tutorials and open source project with code available.

But if you want to build embedded applications, try getting a Raspberry Pi(huge waiting lists though), a familiar Linux environment
I'm so glad that I watched the first of these, and I think I will also enjoy the second. Since it required a bit of searching due to the very short mention at the end, the "Vivaldi" KDE tablet can be found at http://makeplaylive.com/ , which cites a "target retail price of €200" for the tablet stack.

Related to this, I have been helping seed the torrents and distribution of a new flavor of Kubuntu called Kubuntu Active, which can be found at http://cdimage.ubuntu.com/kubuntu-active/releases/precise/re... . Like the Vivaldi tablet mentioned, it's based on the KDE Active stack and is thus optimized for touchscreens. I'm going to try this live CD out on my convertible tablet PC, once I can find a CD to burn it to. I was already very surprised to find that six months ago my upgrades magically enabled multitouch, but at the time it seemed like the only multitouch gesture anyone had programmed for was pinch-to-zoom in KDE.

Since it might also be relevant, in the vein of "send money to support businesses which ship Linux," shortly after I bought my current Fujitsu laptop I found a nice company selling Linux laptops called System 76: https://www.system76.com/ . While they don't seem to be selling convertible touchscreens yet, they do make some very pretty and cost-effective laptop options. (Full disclosure: I am plugging them in part because I want them to stay in business, because I want to buy from them whenever I need my next laptop.)
It actually does mention the price of the cartridges, in the store. $50 each, with discounts if you buy more than one.

Firstly, that's a ridiculous thing to say.

But when it happens (and it does - see Jean Charles de Menezes) it will be put down to insufficient budgets, manpower, equipment and training. So far from coming to a head, it is perpetuated - bigger budgets, more people and more kit.

Would you use it: A new address book?
I've been thinking about a problem I had for quite a while now: Contact information that are out of date from people that I haven't talked to in a while or are missing altogether (like postal addresses) because I didn't add them.

Here is the core idea:

An app that works as a better address book but can automatically inform your friends or certain groups whenever you change your profile (job, address, phone number, website, important milestones etc.). The app will automatically push the update to their address books or send them a notification when they don't have the app installed. The same will happen, when they update their own information.

Would you use it?
Anecdotally, most computer scientists I know (excluding undergrads... I'm talking about PhDs, graduate and professional academic researchers etc.) don't write code and do a fairly poor job when they try.
Ah, so it does. Still doesn't say how big they are. ("1 Cartridge prints 13 to 14 mid-sized creations" is a magnificently useless piece of information. The only number that matters here is kilograms. How many kilograms does it mass? Why doesn't it say?)

"UTF-16 is the worst of both worlds—variable length and too wide"

Really, the author tries to convince the reader, but it's not that clean cut.

One of the advantages of UTF-16 is knowing right away it's UTF-16 as opposed to deciding if it's UTF-8/ASCII/other encoding. Sure, for transmission it's a waste of space (still, text for today's computer capabilities is a non issue even if using UTF-32)

"It's not fixed width" But for most text, it is. Sure, you can do UTF-32 and it may not be a bad idea (today)

Yes, Windows has to deal with several complications and with backwards compatibility, so it's a bag of hurt. Still, they went the right way (internally, it's unicode, period.)

"in plain Windows edit control (until Vista), it takes two backspaces to delete a character which takes 4 bytes in UTF-16"

If I'm not mistaken this is by design. The 4 byte characters is usually typed as a combination of characters, so if you want to change the last part of the combination you jut type one backspace.
Amazing stuff, thanks for the link!

Ah, it seems prices have nearly doubled since the last time I bought from there. MakerGear had a similar price increase, and Rick posted a notice:

" 4/9/12 - Please note that we have experienced a significant increase in pricing from our supplier. The above pricing partially reflects this increase. We hope that the increase is temporary and that as more suppliers come on-line, that pricing will be able to be reduced."

That is unfortunate, as I believe everyone in the US was getting PLA filament from the same extruder in Ohio.
The DNS propagation checker -- is there an existing framework that this site interfaces or is it something that they rolled out on their own?

This is a time for revolution in the methods of science and the funding of science, long overdue and enabled by the internet. It will be a mix of removing the barriers to entry, blurring the priesthood at the edges, open and iterative publishing of data, drawing crowdfunding directly from interested groups of the public rather than just talking to the traditional funding bodies.

Astronomy has long been heading in this direction, actually - it's a leading indicator for where fields like medicine and biotechnology are going. People can today do useful and novel life science work for a few tens of thousands of dollars, and open biotechnology groups are starting to formalize (such as biocurious in the Bay Area).

There is a lot of good science and good application of science that can be parallelized, broken up into small fragments, distributed amongst collaborative communities. The SENS Foundation's discovery process for finding bacterial species that might help in attacking age-related buildup of lipofuscin, for example: cheap, could be very parallel. In this, these forms of work are much like software development - consider how that has shifted in the past few decades from the varied enclosed towers to the open market squares below.

This greater process is very important to all of us, as it is necessary to speed up progress in fields that have great potential, such as biotechnology. Only a fraction of what could be done will be done within our lifetimes without a great opening of funding and data and the methodologies of getting the work done.

> anti air missiles being installed in random flats

The reference to a "High Velocity Missile system" implies that the weapon in question is the Starstreak HVM system (http://en.wikipedia.org/wiki/Starstreak_%28missile%29). Starstreak is a man-portable weapon, so nothing would need to be "installed" anywhere; it'd be a couple of guys standing on the roof with a Starstreak tube.

> triggering those missiles

As far as I can tell, the only way to "trigger" a Starstreak launch is by physically pressing a button on the launcher, so the risk of remotely triggered launch is pretty low. And even if a terrorist or group of terrorists managed to somehow neutralize the Starstreak operators, seize control of the weapon and launch it, the missile itself is so small it wouldn't really matter; the backblast from the launch is negligible (it has to be, for the missile to be safe to launch from the operator's shoulder), and the warhead is just three darts with around 16 ounces of explosive in each. The terrorists would do more damage if they stole bowling balls and dropped them on people from the roof.

> uselessly expensive

Presumably the Starstreak missiles in question have already been bought by the British army, so the only expense would be the cost of having the guys stand around on the roof all day. And since those guys are soldiers the British government is going to be paying them that day regardless of where they happen to be standing.
Re shallwedive the request invite button is a bit off in ff - mid left of the email box. Works fine in the other browsers. It would be cool getting an awesome picture of the ocean as the main background (think flipboard).

To answer your question of what motivates me - vision and knowledge of what Steve Jobs once said, (along the lines of) - "what ever you see in this world was made by people no more smarter than you".
Yeah, it's not the UI. It's not that great of a UI. It's the $200 price combined with good marketing and the promise that you have access to a lot of content on it, be it books, music or videos.

If someone would compare them rationally, they'd see that a "real" Android tablet that costs around the same would have almost no disadvantage and a lot of advantages compared to Kindle Fire: a lot more apps, higher flexibility for anything, better browsers, app sideloading, and on top of all that, they'd also have all of Amazon's services:books, music and videos. So a $200 Kindle Fire would have almost nothing over a $200 Android tablet.

The only problem is that so far none of the manufacturers did that great all-encompassing marketing for a single tablet that offers you a lot of "benefits" and not a list of specs. Amazon did that, and they saw success. I'd like to see at least Google do that with their upcoming (rumored) Nexus tablet.

Being the first to $200 for a tablet that was seemingly as high-quality (or close enough) to an iPad 2, was a big first mover advantage for Amazon, too. A Google tablet that is $200, or even $150, would help. But it might get the same level of impact only if Google is the first to a "quality" tablet that costs only $99. If Google would do that first and promote the heck out of it and what you can do with it, I think many millions of people would want one.

I doubt they could do it this year, but early next year with the 2nd generation it might be possible. But they better do it before Amazon. Because Amazon will definitely go that direction, since their intention is to only sell a massive amount of such devices, to get users to pay for their content.

What I meant was that if you ask the average Brazilian, even those that are much older, you'll see a greater acknowledgement that remixing content is considered fair use culturally and popularly. In the US, there is just as much remix culture, but it's not culturally or popularly considered fair use by a large percentage of the population. In the US, most people would be like, "they used 5 seconds of another song in their remix, they need to pay royalties!", whereas in Brazil, most people would be like, "Srsly?"
Great job for launching something! Not only did you accomplish that, but you're also making a noble attempt at sharing educational resources. Great work, and best of luck!

How could we avoid acronyms like 'utf-8'?

We can do better than that. Unicode8?
How a tweet about a XSS bug within Google+ leads to XSS within InformationWeek
I suspect this is mainly because Windows C++ programmers are the largest group that they feel need convincing. Which isn't totally their fault, Microsoft haven't done well by them by not offering good support for UTF-8; you can convert to/from it using WideCharToMultiByte but that's pretty low level, and higher-level APIs like CString will cheerfully munge UTF-8 strings for you. They also tend to conflate Unicode and UTF-16 which again doesn't help less experienced programmers realise that there might be alternatives.

I've been through the Windows Unicode stuff at a previous job, which ended up using mostly UTF-16 with some UTF-8 for interfacing to third party libraries and for files which needed to be backward compatible to ASCII (plus significant space savings, which I fought hard for). I think I prefer that approach though, since after the (difficult) conversion you didn't need to worry about encodings in 99% of the code. By their rules you'd gain significant complexity by transforming all over the place in any non-trivial GUI code.

This article while citing some legitimate concerns fails to recognize that Google wins as the mobile platforms being used continue to support Google Advertising. From what I understand Google's biggest goal for Android is to keep one company from becoming an monopoly and as a result keeping Google out of the business of advertising to those consumers.
You are right

What does engineering sample mean? I could go to Microcenter right now and buy a Core i5 3570K right now if I wanted to. Are they selling engineering samples? That seems like a somewhat shady move.
The problem comes when the Kindle Fire is the most common tablet Android, and the rest of the Android tablets are seen as the "hacked / incompatible" versions. Given the Kindle Fire is now over 50% of the Android tablets sold[1], that might not be a long time. Citi's recent announcement of its Kindle Fire app[2] tends to worry me.

I think your eye condition may exaggerate the effect. Even the most highly-realised modern games are still noticeably unrealistic, but we're certainly heading in that direction. As we get closer and closer to realism, I'm sure more and more people will start to experience what you describe.
The takeaway I got from this article is that if I use solder to attach my heatsink to the spreader on my Core i5 2500K instead of thermal paste, I could get a big jump in heat conductivity. Now if only I had the tools to create a solder point that large...
I think the issue with Android is that without CyanogenMod, most android users would have no way to go to the stock experience that Google has designed
Those tools suck.

Yeah, one of the long term benefits was that you could work there your whole career, if you wanted to. By the mid-80s though, it was clear that layoffs were to become a regular fixture of corporate life.

still, text for today's computer capabilities is a non issue even if using UTF-32

That obviously depends entirely on what kind of application we're talking about. Keeping large amounts of text data in memory as efficiently as possible is one of my greatest concerns. Many people are processing lots of text nowadays, more than ever before.

"It's not fixed width" But for most text, it is.

True, so ignoring it means that your code will be correct ... most of the time.

A comparison of /tmp, swap and encryption install time options (Linux/BSD)
because to exploit it your injection only needs to alter one part of the statement, as opposed to altering one part of the statement plus the table being altered on.

SQL injection or other auth type vulnerabilities that allow you to alter field values are a lot more common than those that allow you to run a general statement to alter another table
So we should call it "Unicode-8" to further confuse people about the difference between "Unicode" and "UTF-8"?

Yeah, back then you actually had to read documentation (yes, it existed) and more or less know what you are doing. Copy/paste coding and questions from colleagues like "How to connect to datbase, pls help urgently!" were unheard of.
"One of the advantages of UTF-16 is knowing right away it's UTF-16 as opposed to deciding if it's UTF-8/ASCII/other encoding."

It is actually not that simple. By using UTF-16 you already have at least two problems:

1. You should know if byte order is big endian or little endian.

2. You should know if your API supports whole unicode set or only 65536 symbols. E.g. Windows API. Do you know answer? What will happen if your user wants to abuse your system by using symbols outside those 65536.

That's why I'm hoping that starting at least with 2013, all of Motorola's devices will use stock Android. It would make no sense to have a separate division inside of Motorola that once the Android team develops a certain version of Android, then it runs through them so they add more modifications before they release it to market. They should just use it as it is from the Android team, and ship it to market fast.

It would even be a (pretty major) competitive advantage if you think about it, considering nobody does that, and there are quite a lot of people that want stock Android. The other manufacturers have no reason to complain, since they can always do the same, too. And if they were so against a stock version of the OS, they would have never used WP7. But they did, so that tells me that they wouldn't be that upset about it.
Cyanogenmod 9 for quad-core HTC One X released (Unofficial Version)
The problem with that is, Amazon can sell hardware at a loss, fully expecting to make up the cost from people purchasing wares (books/music/anything on amazon) on their devices. While Google does make money from the Android ecosystem, I doubt it's enough/direct enough, to begin selling hardware at a loss.
No. It's not about plotting curves and axes.

It means you have a steep curve to climb to learn it --ie an allusion to climbing a mountain.
I don't know what a "genius" really is, unless it just means someone who's a) prolific in an intellectual field, b) releases high quality work and c) maybe contributed to a fairly "revolutionary" understanding of their field.

But it's unlikely that Feynman is "the last great American genius". Maybe the most well-known example is Chomsky (but there are no doubt many others), and he answers his emails quickly. So, it's not like we necessarily have to pore through notebooks and quips of dead people, guessing at their mental states.
You might want to look at the history of a certain banana dealer before making the statement that a company wouldn't stalk and kill you[1]. A bit of a bizarre story, but don't rule such things out.

This article lists a few characteristics that intelligent and successful (for some definition thereof) people have. The characteristics seem to be neither necessary nor sufficient and the examples are clearly cherry-picked. If there's any scientific or research basis for asserting them, the author hasn't shared.

It's like the author looked a some intelligent people and superficially extracted their secret. It's like looking at a successful company and concluding that the reason for their success is that almost everyone is titled an Associate rather than their flat hierarchy.
Great Job Jai!! Beatbar rocks!!

I think the author's basic point is that if we standardize on utf-8, that "8 bit anxiety" goes away.

I did my first programming assignment on punched cards, so I probably have permanent ASCII/EBCDIC brain damage. However, this article decisively convinces even me that utf-8 wins and other encodings represent fail.
or maybe it's a feedback loop?
That's a cool point about parallelization. There was a fascinating experiment done a few years ago by the mathemetician Tim Gowers, called the 'Polymath project', where he took a problem in math, and asked for the mathematicians who read his blog to solve parts of the problem. 40 people took part, and 7 weeks later, Gowers announced on his blog that the problem was 'probably solved'. A couple of papers came out of it, published by 'D.H.J Polymath'.

More info on this is on the Wikipedia page http://en.wikipedia.org/wiki/Polymath_Project

You're right, it would be cool if we could see more of this kind of thing happening. There is now a whole site dedicated to applying parallelization to other problems in math http://polymathprojects.org/
