Mod parent interesting. Can anyone explain what happened in that scenario? Is it a load impedance issue? And, wouldn't there have been a diode to prevent current flow into wrong direction?
In what way is it "good and practical" to ignore a standard
For starters, it allows me to burn and read optical discs. Most external DVD drives want to suck all the power through USB and, while they might have a separate DC power connector too, finding just the right power supply is a pain in the ass. If everything was done properly, every external DVD drive would ship a discrete AC/DC power supply, because the USB spec does not actually allow delivering these crazy, over 1A currents which is needed. But what can you do...
possibly damaging electronics which assume the standard by providing a variable non-guaranteed maximum current?
You are of course correct. As a comment above by SuricouRaven pointed out, letting big amounts of current through can cause hazardous situations.
Linux fully supports TRIM and failure to enable it will not damage the device in any way.
Linux does not fully support TRIM. It is the very reason why many distros do not automatically enable "discard" in fstab. As noted in the summary: "the kernel performs TRIM to a single range, instead of vectorized list of TRIM ranges, which is what the specification calls for. In some scenarios this results in lowered performance".
Hey guys. If you are interested, I have formed a startup which makes a product called sfcrazy OS. It does not adopt existing technologies or paradigms from any other operating systems. We also believe it performs much better.
When it comes to USB DVD drives, some laptops cannot give enough energy to keep the disk spinning. There's a category of machines which seem to ditch the USB power regulation spec and just connects the USB Vcc rail to the 5V rail of the laptop. That's good and practical in my opinion. Then there's the another category which try to limit the power and have a polyfuse or something more smarter in place.
What really hits my nerve is the bug which causes the brightness to be adjusted in double steps on laptops.[1][2]
The brightness change event is probably processed by two recipients. Maybe the OS grabs it and does the adjustment but lets the event to be handled by BIOS too. Or maybe there are two handlers for the event inside the Ubuntu power management system.
Anybody, see it for yourself. Install Ubuntu on a laptop and wank the brightness up/down. On most laptops it goes two steps. Usually this temporary workaround fixes it:
We get it. You seem like the classic foam-mouthed person who loves Linux and hates everything Microsoft touches. Bonus points for writing "M$ Windoze". Year 2000 called and wants your rant back.
There is an undocumented setting in the TV configuration which supposedly disables this behaviour, but an inspection of the network traffic between the TV and the Internet showed that the TV continues to send the data whether or not the setting is disabled. DoctorBeet contacted LG, but they shrugged the matter off, saying that it's a matter between him and the retailer he bought the TV from.
What is it these days with companies not taking any responsibility of their products starting from the point they leave the factory? It's unethical and just wussy-ass behavior to not stand behind your products. You don't "shrug the matter off". You must care about customer satisfaction. From a good company the correct answer would have been "at your service, sir". After that they would have start working hard to provide a firmware update which allows properly turning off the spying feature. If you bother to wake up in the morning to make televisions, at least do your job properly.
Pretty much the same thoughts. At first I thought Bitcoin was a cool liberal money system and I supported it. But now I'm starting to think that maybe it's actually good that there is some level of real trackability for monetary transactions. Sadly Bitcoin provides a tool for criminals to send "black money" easier, which in turn helps to make the world a shittier place.
I named them "magic tricks" because they weren't targeting a known specific problem but rather advising "try reseating everything, if something does the magic".

Aahh, thanks for that. So it actually is W = J / s. Damn I suck at mathematics, I constantly keep doing simple mistakes.
Yes.

This should be basic Quality Assurance stuff...
It makes you wonder what other optimizations are not being done but are done in Windows.
I'll toss in one: in Windows 8, an USB memory stick is automatically powered down if it is mounted but has not been in use for a while.
Well, in that case it would be nice bonus to be pointed out in which way I was wrong. :D
And when will beta.slashdot.org be rolled out?
You can still use Windows 7 for a long time.
Exactly. It's power, guys. :) Energy is measured in joules (W/s).
Of course not. I certainly didn't mean it that way.
No, I just happen to live in the real world.
They will shit their pants when they see the open office suite completely messing the layout of the documents.
And then came Windows 8....
You can still run Windows 7. It will still be supported for over 6 years.

My expectation is that they can coexist.
Also, VR is the state-owned railroad company in Finland. And railroads were a quite recurring theme in HL2. Pure coincidence? I think not!
I found this interesting Google+ post from the Muktware article comments.
I personally am seeing BSDs as an increasingly interesting choice.

What about the talks about NSA being able to defeat SSL already?[1] [2]
