    There, fixed that for you.

    Last Thursday I booked a normal taxi (in Oregon) to take me to the airport. He picked up another guy as well. He asked us first and we got a discount (but the driver made more.. the discount was not 50%).

    So I don't see how ride sharing and taxi service are mutually exclusive.

    How is that a ridiculous amount of electricity?

    1W is about the same power as an apple falling 1 meter onto your head once per second.

    Do you want 1000 apples falling on your head every second?

    24kWh/day = 24kWh/24h = 1kW. Which is a completely ridiculous amount of electricity.

    I can't do sums while jet lagged clearly.

    48kWh... about 3500 kWh/year, or about 9,6 kWh per day.

    What is wrong with Watts? W*time/time = W. Why add the redundant time/time ?
    Bloody furlong per fortnight weird units.

  8. If you've followed US politics over the past few years, it's not surprising at all. Rand is the only Republican that groks IT at all. If he wasn't also in the Koch's pocket, he would be the perfect candidate. He's still far better than Hillary "what email server?" Clinton...why the Republicans won't actually nominate him I'll never understand. He would pull conservative Democrats to him, and is a positive force for both Libertarians and Progressive Republicans (in the vein of Eisenhower). He's spoken out against the NSA, against drones, He's an actual MD. He voted against extending the PATRIOT Act.

    My main issue is he's too anti-government, and wants to cut into the Department of Education, and is way too "pro-life". But weighing these against his positives, we'll not find another candidate who scores better. Of course the Republicans will give the nomination to someone else; someone who is more in-line with the $$$ and is a war-mongering corporate shill instead. And when they do, Hillary will sweep this election...it's almost like the Republicans like loosing on purpose.

    RP is indeed a mixed bag of much needed reform and batshit crazy.

    For a tree hugging liberal, I am however fully on board with killing the department of education. It's not that a DoE couldn't work. It is that the current one has always been a force for evil in schools. This is simply an example of the thing in question no coming even close to what a tree hugging liberal or a baby eating conservative would hope for from a government department. Centralizing some education stuff is entirely sensible, but they tried it and they failed again and again and just made things worse. But yes, he's anti government by default and want to do stupid shit like axing the federal reserve as well.

    I want him to have a love child with Elizabeth Warren. Let the spawn be the president.

  9. Alarmingly, the somewhat serious contender is Rand Paul, instead of Ron Wyden, who is much better and seems to piss of the left and right equally, which gives evidence that he's a sane person.

    So it might work in some constructed scenario, but not in the general case, which is what a WiFi physical layer needs to address.

    There are plenty of directional antennas that are manually configured by the installer, but that's different to trying to track a STA with a beamformed ray from an AP. That's crazy talk.

    The article states that the earlier figure was incorrect; the Baltimore police actually used it 4,300 times, not 25,000 times.

    Is this one of these things where they try to make 4300 sound small by first quoting a bigger number?

    Well swift has a bucket load of nice clean language features for a compiled language.

    Can you name 3? (insert cricket chirps here)

    Inferred types, for less typing and typos.
    Tuples, very handy for lots of uses.
    Simple iteration syntax.

    None of these are new, but the ensemble is nice and clean in a compiled language. I like python for its simplicity and power, but it's generally interpreted. Swift is a but pythonic, but compiled.

    Since when is a disc mounted permanently in the computer case considered even remotely a backup option?

    When it's a second disc with a copy of files from the first disk, or a raid-0 mirror disk.

    Good for backup from hardware failures. Not so good at backup from malware. Back up from malware needs to be on a remote machine that isn't mounted into the file space of the backed up machine so the malware can't infect it. That's why I have both. Local mirroring and a backup system that scp's the files periodically over the network.

    Our senior project/software engineering class/writing intensive capstone class... was a JOKE... the school formed a second section when they saw how many wanted into the class. The prof was paid 1/3rd of a normal class.. thought he was only getting a few students... and ended up with 25.

    Anyway... the class turned "learn swift at the 101 level" for 2 months and work on a meaningless project you would never, ever show a prospective employer for the other 2 months.

    I hate swift. It's like writing javascript with a keyboard made of razor blades. Nothing ever works. Nothing ever feels right.

    I suspect you hate xcode. Swift is fine. xcode is a project obfuscation system.
