BT Infinity (FTTC, uncapped) doesn't seem to suffer from throttling at any time - I get the full 40 Mbps.

However, I often need to switch ports after a download has started to realize full speed. I don't know if this is a quirk of my BitTorrent client, or whether there is actually throttling that's broken by the port switch. Worth trying if you're having trouble, though.

TinyMCE is not an addon - the article seems to be talking about a Firefox bug, but doesn't provide a bug ID.

Addons are now up-issued automatically where possible; I have found fewer addons breaking compared with the sweeping changes made using the old model of major releases.

The article also misses the benefits from regular releases: features and improvements get in front of users more quickly, and changes are incremental, rather than jarringly abrupt. See http://en.wikipedia.org/wiki/History_of_Firefox_(Rapid_release_development_cycle) for a list of changes since Firefox 4.

I can find no reference to the Channel Tunnel project ever being referred to as the Eden project, but possibly it's been swamped by the biome complex in Cornwall, which is known by that name. You're welcome to provide a citation, if you have one. (Incidentally, the Eden Project was an engineering challenge in itself, given the difficult conditions found in the clay pit it was constructed in. It's well worth a read on the subject - Wikipedia doesn't have much to say about it.)

w.r.t. the TBMs used in the Channel Tunnel, they weren't all built by the same company, and they operated in different modes. There weren't even just two. More info at http://www.batisseurs-tunnel.com/amicale/doc%20UK/3%20Tunnels%20Tunnel%20sous%20La%20Manche_C%20.pdf

The Eden project had nothing to do with the Channel Tunnel (in fact, needed no tunnel construction at all), and the latter used different types of TBM from each end.

I suspect you've just done the equivalent of equating all types of car as identical, the only difference being the number of passengers carried, type of fuel, and terrain they need to be able to handle.

Actually, I think it's a code quality issue.

Look at http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.35.y.git;a=commitdiff;h=d4d67150165df8bf1cc05e532f6efca96f907cab

It seems to me that the critical line of code reloading EAX was deleted because the committer couldn't see why it was necessary, and there was no comment in the code to explain its purpose. With no comment, and no unit test to guard against regressions (and I recognise that isn't always practical), this was an accident waiting to happen.

From a slightly older article on the same blog:

The load time data is derived from aggregated information sent by users of your site who have installed the Google Toolbar and opted-in to its enhanced features.

So this isn't quite as susceptible to people playing games with Googlebot as it might appear.

Agree that the left foot should only be used to operate the clutch on a manual transmission, but disagree with the rest of your advice.

Following your advice, if your foot were to slip off the pedal under braking (perhaps if you hit a pothole), the car will have no engine braking effect to keep it under control and you'll most likely hit whatever you were braking for, or overshoot your corner. The shift down or to neutral should come when you've lost most of your speed (obviously depends on how high your gear is), or when you're about to accelerate again.

Similarly, when starting off, releasing the handbrake (aka emergency brake) before setting the clutch will result in you rolling forward or backwards if you are stopped on a slope, or even jumping forward if you panic and overshoot the bite point. Unless you're on the flat (typically in standing traffic), always find the bite point before releasing the handbrake.

This should be modded insightful, not funny. All the injuries I've ever had have come from sports, not idleness or walking for pleasure.

Sitting still too long might not be healthy, but the reality is that your diet will have a much greater impact on your health than exercise ever will.

TFA says "I want a game that recreates that insane rush of endorphins and adrenaline or whatever it is..."

I reckon you can get pretty close to that with some multiplayer game scenarios. Something simple, like Wolfenstein Enemy Territory, where it's just you and a friend, sneaking over the snow into the enemy base while the battle rages behind you... and the path ahead is mined.

A High-Res 3D Video of the Embryonic Heartbeat 207

Posted by timothy

An anonymous reader writes "Researchers at the University of Houston, TX, adapted an imaging technique called optical coherence tomography to capture 3D video of the mammalian heart as it forms. They used the method to image a mouse embryo just 8.5 days past conception and about a day after it starts to form. In the remarkable video a normal heartbeat is visible. Normally optical coherence tomography is used for clinical imaging of the retina. Having such a high-resolution, non-invasive way to image the developing heart could perhaps help doctors treat congenital heart disorders in human babies."

+ - Automated Propane Tank Monitoring?

hrbrmstr writes "We just moved into our new house where we have two decent-sized above ground liquid propane tanks that feed the dryer, hot water heater and backup generator. I googled for solutions for residential propane tank level monitoring (since we need to call the provider when it gets down to 20%) and really didn't find anything of use (there's a Robert Shaw device that won't work in this application). I'm looking to roll my own either with a wired or wireless, low-light camera above the gauge which I could write a program to snap an image of and determine the level. If I go that route, I'd like recommendations on good and preferably inexpensive cameras that can operate at close range to the gauges for said application, but I'm also curious as to whether other DIY slashdotters have rigged something up to do the same thing or have suggestions for replacement gauges that can be tied into a ZigBee, Insteon or X10 home automation system. I realize the very doable low-tech solution of checking the gauges a couple of times per week is not exactly a laborious task, but it would be much cooler to get it going digitally."

Aren't you glad you're not getting all the government you pay for now?
