I'm very likely over-reading this, but my first reaction when seeing this was: don't learn to use Python and code your own stuff. Learn to use JS and code for the Google platform instead. Learn to become a tenant farmer.
It's basically what Google does: sponsor a high-bandwidth network to a town -- get them connected and to use Google services. Teach kids AJAX -- get more web coders, ultimately more profit to Google.
Most of these potential vaccines turn out to be unworkable - but try long enough and hard enough, eventually scientists will hit upon a really good one.
I agree. We've seen these headlines before on Slashdot, but they seem to be getting more and more closer to the target each time.
I guess there was some significant trend of failures with Maxtor disks. People said that service departments could see statistically higher returns of Maxtor brand. I never saw the numbers though. I personally had one 40GB IDE Maxtor disk and it was rock solid, one of my best 3.5" HDDs.
Technically on mechanical drives, ext4 benefits from defragging... So does btrfs.
I don't think there is a file system which would be completely immune to fragmentation. The reason why ext4 is often touted to not fragment badly is because it tries to spread the files across the disk instead of storing them sequentially (like NTFS and many other file systems). I don't know what kind of strategy btrfs uses.
Technically same thing on NAND based SSDs (opening a page takes a few us for MLC).
This is what I've been thinking too. Defragmentation is usually not recommended for SSDs, but as you say, one would think that reading full pages would actually provide a slight performance improvement. Then again, the contents of the SSD might be remapped to arbitrary places due to wear leveling, so the OS might not see the physical linear structure of the disk anyway. Thus the defragmentation would have to be done with some kind of cooperation between the OS and the disk, for which there exists no implementation.
BTW Don't allow an NTFS disk to exceed 50 percent full or you will suffer data loss/corruption - don't believe me? Check the MS Knowledge base and yes it still applies to Win8 since it's using NTFS.
Ok, I don't believe you. I will check the Knowledge Base as you suggest. Now can you provide the KB article page in question?
There is actually another recommendation which is to leave 12.5% free to prevent the MFT from becoming fragmented. NTFS reserves 12.5% of volume by default for exclusive use of the MFT. This space, known as the MFT zone, is not used to store data unless the remainder of the volume becomes full.[1]
Shuttleworth is threatening Linux users' elite club by finally showing signs of actually making Linux work on the desktop and popularizing it. That's what pisses people.
I think that most drives of this nature have 0G sensors and off-load the heads when they detect they are in free-fall.
Not saying it is a good idea to play catch with your hard drive on a paved road, but there is some protection built in.
Some time ago I dropped a 500GB Toshiba 2.5" HDD when it was out from a computer (so the drive was off and the head parked). It took some rough-looking flips around itself when it met the floor. After I plugged the drive back later, there was no detectable damage. No weird noises, no data corruption, works perfect. Nice.
Wonder how well the drive can take constant shocks and jostling that tablets are subject to. I may not be a HDD expert, but I wonder if just the tapping on a screen might be enough to cause a head crash, especially on a higher RPM drive.
There is no way that tapping the screen would cause a head crash with any hard drive. Disks inside laptops would be dead too soon if that was the case. However if you drop the tablet on a floor, we can start talking about whether this kind of drive would be damaged. Obviously, flash memory will be better in that kind of situation. Of course there are other components to take into consideration too, such as the screen, which might crack when the tablet is dropped.
I have an Atom 270, and the graphics support sucks, but I don't complain about it, it's just the reality of using shitty vendors, in this case PowerVR, who refuse to let Intel divulge documentation for their shitty GPU to anyone without an NDA*.
So the Atom N270 uses Intel GMA950 graphics core integrated to the GM945 northbridge. PowerVR is newer stuff.
My father was once working on a forest stitch photograph he had taken and I had to warn him after I saw him saving the picture as JPEG between retouches. There must be countless of hobby artists who save their work as JPEG while working on it, not knowing that the quality is compromised on each save.:(
I don't know either. Whatever the issue is, it should be fixed and then Linux will be even better platform. But that does not explain the slow desktop effects. They are choppy under Linux on Atom platforms too, and once again, smooth under Windows.

A netbook would be all that.

Quite abnormal, actually. Servers and connections are so beefy these days that the Slashdot effect is met only rarely.

I guess we can think of the SSD being the "suicidal squirrel".
But how many SSDs actually implement that strategy properly?
The two dictionaries I checked, including Merriam-Webster, don't list "performant" as a word.
What was the other dictionary?
So I guess HAMR is still in the labs.

The sad truth is that these days I usually blame Linux for the sluggishness. :/ Well, not the kernel, but the desktop.

I've read the article on Wayland at Wikipedia, but I still don't know why they want to replace X.
The X graphics stack has bad performance.
He's using a $29 inflatable doll which requires constant patching.

They'll never regain the trust of their users, along with Microsoft, Apple and all of the other bend-over-backwards in the US.
Give it a year or two, and no one will even remember the NSA/Google scandal anymore. Sadly.
Why would anyone think that mimicking object-oriented constructs in C is better than C++ OOP programming?
Wow wow dude wait a second, are you trying to suggest a practical solution? ;)
