Submission + - Adafruit launches educational show aimed at kids (hackaday.com)

anavictoriasaavedra writes: Adafruit Industries just posted the first episode in a new educational series aimed at teaching kids about electronics. The episode is entitled “A is for Ampere” and teaches the basic theory behind electrical current. The subject seems like a common one for A-to-Z themed electrical tutorials. And yes, that's Collin Cunnigham as André-Marie Ampère.

How Could Swarms of Robots Help Humanity? 67

ceview writes "Researchers at Sheffield Centre for Robotics have demonstrated that a swarm of 40 robots can carry out simple fetching and carrying tasks. This is done by grouping around an object and working together to push it across a surface. They believe that this could provide opportunities for us mere humans to harness such power to do all sorts of things like safety — what like catching falling workers perhaps? Youtube action here."

Emscripten and New Javascript Engine Bring Unreal Engine To Firefox 124

MojoKid writes "There's no doubt that gaming on the Web has improved dramatically in recent years, but Mozilla believes it has developed new technology that will deliver a big leap in what browser-based gaming can become. The company developed a highly-optimized version of Javascript that's designed to 'supercharge' a game's code to deliver near-native performance. And now that innovation has enabled Mozilla to bring Epic's Unreal Engine 3 to the browser. As a sort of proof of concept, Mozilla debuted this BananaBread game demo that was built using WebGL, Emscripten, and the new JavaScript version called 'asm.js.' Mozilla says that it's working with the likes of EA, Disney, and ZeptoLab to optimize games for the mobile Web, as well." Emscripten was previously used to port Doom to the browser.

as I've grown a little "less young" (ahem) I've started to have slight issues, and in particular I notice that if I work right up until bed, I toss and turn worrying all night

Maybe you're an insomniac. Even as a baby I didn't need much sleep, my mom used to say how when I was a baby she'd look to see how I was while in bed and I'd be quiet but wide awake. I've settled down some in my middle ages, what with the all the therapy I've had and the prescriptions I'm taking but even when I was 45 years old I'd be awake almost 60 hours straight, get 8 hours sleep then be up another day and a half before getting another 8 hours.

if I run home from work (about 10 miles) I feel awake all evening (good) and into the night (bad).

How are the roads, or other pavements, and traffic? If they're good then maybe you can ride bike or skate. Around here, Minneapolis/St Paul, we have some bike/hiking pathways people use to go to and from work. At least when there's no snow. Of course not everyone is even near one but many are.

The article notes that LimeWire is used by nearly 60 percent of the people who download songs

it should also be noted that about 95% of infected computers have limewire or some other gnutella client installed. i don't know why but gnutella is just riddled with digital herpes.

Sure, maybe cosmic rays are causing a false reading, but oddly enough, quite often when it says "O2 sensor is reading incorrectly", the O2 sensor is bad.

Often, yes, the sensor itself is bad...but in my experience, trusting the OBD II code without any further investigation is a quick way to ensure that customer comes back. Bad gas, a bad catalytic converter (depending on where the sensor is, of course), a clogged intake manifold or throttle body...hell, even an air filter can cause an O2 sensor code to trip, if it's old and dirty enough.

Fast-working mechanics would just replace the O2 sensor. Good mechanics make sure the O2 sensor really is the problem before they replace it. Like I said, OBD II codes provide a starting point for a diagnosis, not an end point.

Search for "google news outage september 22". (I don't know what comes up on Google; I use Yahoo as my default engine.)

Here's a good link. Google Outages Damage Cloud Credibility. It came a couple of days later and gave a roundup of recent Google outages. Specifics about that outage: look here.

I think it was particularly newsworthy because (a) it came on the heels of several other outages; (b) /. has had several stories about the debates with newspaper publishers, online aggregators, pay for content, etc.; and (c) this was now leading to questions about "is the cloud ready for prime-time" beyond just Google.

(Update: I just checked the same search on Google, and the first link is their app status dashboard). Looks like GMail has had problems over the last week.)

And the cost of being able to resize from any edge in Ubuntu for example? The need to have a fugly border all the way around every window, which on the one hand consumes display real estate, whilst still being narrow enough that it proves hard for some users to be able to grab easily.

I'm not getting way into this shit-slinging match, but I seem to be able to position my mouse on every corner of almost every window on my macbook without hovering over any active elements. it seems like they could just tick out a tiny section of each corner so that i don't have to move my window to resize it. i don't think people would complain about the edges if you could resize from the corners.

hell, how about top left and bottom right? that would be a start.

And there you are wrong. A menu at the edge of the screen is easier (more productive) to use. Again because of Fitt's law. Plus it also is more economic on screen real estate.

this is wrong in my experience. i have used almost exclusively a mac for over a year, i still prefer having the menu in the window. when a window grabs focus on mac, it changes the menu. if i'm selecting from a menu, and i misclick and hit another window, the menu changes. i don't experience the drastic hit in screen real estate, either, because i can buy a computer or display with better resolution for less or equal money than an apple product. also, when a window is behind another window, i don't feel like it's taking up screen real estate.

i understand the fitt's law argument, and i just think it is wrong for me and quite a lot of users. i think it's a bad idea. some people like it.

- instead of maximizing, the zoom button only increases the size of a window's height or width until the scroll bar is no longer needed (or the extent of the screen is hit.

i see the benefit of this, but only if you have a decent sized display. even still, i can acknowledge that it's a matter of preference. still, my web browser won't maximize, and since i can't resize from the left or top, if i want a full screen browser, i need to drag my window to the edge of the screen and then resize it.

and in linux, i can maximize it either vertically or horizontally, and move my windows with keystrokes. windows can suck it too. :)

When the Facebook era of justices come along, we'll have to face reality and accept that our authority figures are not and cannot be 100% chaste pillars of virtue. That, or we'll just leave the jobs open indefinitely. Considering where the far-right's going with their ideology, I don't feel comfortable ruling out permanent vacancies as the answer.

It doesn't have to be an operational problem. All they have to do is position themselves behind the market, and they will take a huge sales hit.

They haven't done that so far (in the last 10 years...), but they have been on top for a long time, and it is very difficult to tease out just how much of that is by intention (which might run out), and how much is by luck (which will eventually run out).
