Uh, you must not have worked in a shop that does continuous integration automated builds? Do you really think QA should be handed binaries that you compile and have them trust them?

The problem is that GCC will always give you a different binary every time you compile from the same source. This makes it impossible that the binary you received comes from the source you claim to have used. You can get around this by never receiving binaries from anywhere but the automated build machine but it would still be useful to be able to test that a build that you received was built from the code you expect.

There were several reasons why Apple moved away from the GCC tool chain to LLVM and Clang but one of the abilities of the LLVM stack is that you can actually get identical binaries from the same source compiled on different machines at different times.

I once trained an Australian Shepherd to fetch beer from the refrigerator. But I wouldn't recommend it as a business model.

I guess that depends on how you define it. On interlaced broadcast (like all old TV), you get a half-frame every 50 seconds, where half-frame means either the even or the odd lines, alternating.

Why bother finding a dog?

I would agree that 3/4 of AV success is avoiding "dodgy" sites. However, I have never had any problems with malware on any porn site. The sites I have had problems with malware on were like pics of celebrities on Google Images, and you get a redirect to a malware driveby site, or, you lick on an ad that promises things free that should not be ... that kind of thing. I Used to AVG 2012, but when it went to 2013 it refused to activate, so I switched to Avast, and have not looked back. Higher rated and better protection.

The same way we did before GPS, by actually knowing where we were going. I'm nearly 40 years old and never once used GPS to go anywhere and I've never been lost. I've looked at a map a time or two before I went somewhere, but never GPS. I've driven all over the country too and in some very large cities and some very backwoods locations. Never understood why people really needed GPS, seems like a fancy waste of tech to me.
