Comment Re:PKI? (Score 1) 27

Worse than that; in all likelihood.

While adoption has been patchy; the 'trusted computing'/TPM guys definitely have what it takes to deliver a cryptographically locked bootloader and a variety of other powerful-and-somewhat-creepy capabilities; so anyone who gets onboard with this will presumably move from shipping hardware with shitty firmware that doesn't get patches to shipping hardware with shitty firmware that doesn't get patches and cannot be fixed or replaced even if you have the requisite expertise with that platform. The sort of 'support' that bootloader locked android devices get now. Far too insecure to be remotely safe; far too secure for mere mortals to reflash the firmware with something else without a particularly elegant 'trustzone' compromise or hardware attacks.

I hardly mean to suggest that OpenWRT will save IoT or anything(IoT needs a lot more saving than is probably possible for anyone; and vendors are spitting out unsupported hardware far faster than 3rd parties and mainline kernel support can catch up); but if you think shoddy firmware is bad; it's hard to get excited about shoddy firmware that is effectively impossible to replace even for devices based on well supported hardware.

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) 263

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.

Comment Re:LibreOffice? (Score 5, Informative) 121

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 Re:Globalization vs. Protectionism (Score 1) 202

All salaries stagnated.

False. The standard of living in the developing world has vastly improved and billions of people have been lifted out of poverty. This in turn has benefited rich world countries by making our goods more affordable. It has also reduced migration to some rich world countries. Case in point is the USA in which net migration from Mexico is in negative numbers.

At the same time a whole bunch of folks are out of jobs and can't afford to buy food. ?

Where? In the US unemployment is only at about 2 and a half percent.

So could someone explain to me why we hate protectionism?

Because the last time it was tried on a large scale in western countries it set up the economic conditions that led to two world wars.

Comment People like Musk need to do more homework (Score 3, Insightful) 225

Solutions like this are classic examples of tech-rich people thinking they have all the answers when there's a whole bank of qualified specialist people already working in that field who know what's really needed to fix the problem but have only been stymied by politics.

If traffic is driving Musk nuts then the solution is not to find innovative new ways to handle more traffic. The solution is to ask why is traffic so bad in the first place.

Or if that's too heavy, try Suburban Nation: The rise of sprawl and the decline of the American dream.

Only then will you come to see the culprit: Single Use Zoning, aka the BANANA (Build Absolutely Nothing Anywhere Near Anything) rules. Single-use zoning forces everybody to make several car journeys just to get through a typical day. Going to work? Car. Going out for lunch? Car. Going home form work? Car. Need to go out for a bottle of milk and postage stamp? Car. Going to a movie? Car.

No bloody wonder the place is flooded with traffic. You try to build a city around the automobile and it becomes a hostile environment for pedestrians and cyclists. You try to widen roads to accommodate more cars and the laws of induced demand kick in, resulting in even more traffic and roads as choked as they were before.

Learn a few things about urban planning, Elon. Don't arrogantly assume that you're the first person to want to address this problem. Smart growth and sustainable, walkable, transit-oriented development is a far better solution than drilling holes in the ground and cracking puns about the word "boring." It requires years of tedious work and politicking to build support for smart growth. A city is not a private company with which you can do what you like. There are elected councils, public advisory committees, public hearings, tax implications, and all manner of complex bureaucratic hoops that you have to jump through to fix these things.
