Comment Operating System (Score 2) 209

The definition of an OS is that it controls all resources of a computer and shares them between the applications.

That is at best a description of some operating systems.

Some operating systems control some computer resources. Some share the resources that they control.

Comment Re:vGPU seems cool (Score 5, Informative) 90

My understanding is that it is more extensive: PCI(mostly 'e' these days) passthrough allows you to assign a physical device to a VM; but the device can't be shared: if a given piece of hardware is being passed through to one of the guests, none of the other guests or the host OS can use it.

This 'virtual GPU' stuff is supposed to make allocating GPU resources between VMs closer to how it is with CPU time or memory, where all the guests and the host can't exceed the capabilities of the machine they are running on; but they can all have access, with relatively modest overhead, to the same device.

I don't know if things work as pleasantly as desired yet; but in principle it should be a lot more convenient than full device passthrough. Especially in cases where you might be interested in the GPU for its computational capabilities, video transcoder, etc.

Comment Re:Why not blame the manufacturer? (Score 2) 258

If you think that finding a vendor that doesn't keep cutting battery life/SD card slots/headphone jacks/basic safeguards against electrical fire in order to make it thinner, cheaper, or both is hard; just try to find one that ensures sufficient borated polyethylene(with something else to sop up the resulting gamma rays) or other neutron shielding into their products.

There probably are some, making bits for nuclear reactors and industrial, scientific, and medical users of neutron sources; but it's a niche.

Wow. Way to go presenting a calm, clear and coherent argument against the entrenched install base of Windows and showing people that Linux is a viable alternative.

He only just made his Slashdot account on Monday. He hasn't yet learned the value of calm, objective commentary the way you and I have.

Comment Re:LibreOffice? (Score 5, Informative) 118

You can definitely embed Windows Metafile images in LibreOffice on Windows; but I'm not entirely sure if that is enough to make it vulnerable. WMF is dangerous because it is basically a package of GDI function calls, which might be good for efficiency or compactness; but has led to a number of creative and executable things being shoehorned in(as in this case; and repeatedly over the years).

However, there are several image handling libraries that can render or convert WMF images without access to GDI; so in those cases GDI bugs wouldn't be a problem(though you probably have other things to worry about).

This Libreoffice VCL documentation suggests that LibreOffice uses its own VCL WMF filters; but I sure wouldn't bet anything remotely important on that without testing it first; or knowing rather more about how LibreOffice is put together.

Comment Will of the People (Score 2) 185

On Thursday, a Ukrainian man who hatched a plan in 2013 to send heroin to my home and then call the cops when the drugs arrived was sentenced to 41 months in prison for unrelated cybercrime charges. Separately, a 19-year-old American who admitted to being part of a hacker group that sent a heavily-armed police force to my home in 2013 was sentenced to three years probation.

Sergey Vovnenko, a.k.a. "Fly," "Flycracker" and "MUXACC1," pleaded guilty last year to aggravated identity theft and conspiracy to commit wire fraud. Prosecutors said Vovnenko operated a network of more than 13,000 hacked computers, using them to harvest credit card numbers and other sensitive information... A judge in New Jersey sentenced Vovnenko to 41 months in prison, three years of supervised released and ordered him to pay restitution of $83,368.

And now people like this are in charge of our elections.
