LaTex is horrible for programming in. Painful does not even begin to describe the experience. But LuaLaTeX is different - it allows you to script using Lua thereby making what used to be horrible, feasible. Very useful for automatically generating tables based on external data.

Gas stations of the future will not exist unless they are selling gas. The demand for electric charging will not be great enough because the majority of people will charge at home. Competition from restaurants and other service providers will also be present since providing electricity does not require the infrastructure and safety certification required for selling gasoline - at least not if you are charging slow. Some fuel stations supporting fast charges will likely exist but they will not be common and will likely charge a premium for a charge due to the increased cost of the charging infrastructure. The desire to save money will cause people to adapt their driving / charging habits so that fast charges are not required.

People Are Obtaining Windows 7 Licenses For the Free Windows 10 Upgrade 172

jones_supa writes: Windows 7 has quickly started increasing its market share of desktop operating systems, nearing 61%. If you're wondering why this is happening when Windows 10 is almost here, the reason is this: Windows 10 will be available as a free upgrade for those running Windows 7 and 8, and the new OS will have the exact same hardware requirements as its predecessor, so the majority of PCs should be able to run it just as well. Because Windows 7 was launched in 2009, a license is more affordable than for Windows 8, so many users are switching to this version to take advantage of the Windows 10 free upgrade offer.

If you want per-application snapshots then you want the application to be in charge of the snapshots - not the file system. The file system does not know when an application is finished making changes to a file. Possibly many files must be changed - the file system does not know so it can not make any assumptions. Applications should be in charge of their own document snapshots using some form of version control. If one wanted they should script it so that a ZFS snapshot was generated - but you are better of using git.

With regards to ZFS, the snapshots are generally done at whatever frequency is defined by the administrator. 5min, 30min, 1day - whatever they decide. The snapshots are accessed from the root ".zfs/snapshots/named_snapshot" directory. There is no piecing together of files - the full file-system, as it was at the point in time it was captured, is available in the directory. The snapshots are immutable - the contents will never change so long as the snapshot exists.

It is more likely that Apple designed USB-C at the same time they designed the Lightning connector. They opted for the Lightning connector and decided to gift USB-C. It is in Apple's best interest for USB to have a good connector.

Looking at how horrible the USB3 connectors are, it all makes sense. USB 3.1 was announced far to quickly for it to have been planned at the time USB 3.0 was being specified. And there was no design debate - the new connector was basically just announced. Looks like someone delivered a fully developed USB-C connector to the USB standard committee and it was enough of an improvement to warrant a new version.

Comment Re:20% to 40% ??? No. Just no. (Score 2) 597

While you are correct, the article is likely talking about all conversions when powering common DC powered appliances. So 24VDC -> 120VAC -> 5VDC. In this scenario, the 20% to 40% could be realized. It all depends on how crappy the other power supplies are. By minimizing the change in voltage you allow the cheap DCDC converters to work more efficiently.

Bottom line: Encourage people to replace clunkers and keep their vehicle well-maintained.

In Japan, this is exactly what is done. Insurance rates increase once your car is beyond a certain age. You do not see many old cars driving around because they cost more to operate then newer vehicles. At lest this is what my Japanese co-worker had to say.

The mass could be moved forward and back without changing the direction of the bullet - so long as the bullet is rotating. If it stops rotating, say by hitting an object, then it would absolutely start to tumble. But I was referring to moving the mass perpendicular to that. Basically a pendulum inside the bullet. This would result in the bullet tumbling right away if not controlled. But if controlled, could be used to direct the bullet - at least in theory.
