Comment Re:What has changed? (Score 1) 221

There was a time that a citizen could walk right up to the White House.

That lasted until WWII.

Until the 1980s, anyone could enter the Pentagon and wander around the corridors. (George C. Marshall, Army Chief of Staff, decided during WWII that there was no way a building with as many people as the Pentagon could keep spies out, and requiring badges would give a false sense of security.) In the 1960s, anyone could enter most Federal buildings in Washington, including the Capitol and all the House/Senate office buildings, without passing any security checkpoints.

Comment The President was out. The Secret Service did OK. (Score 3, Insightful) 221

It was a Friday evening. The President had left for Camp David earlier, and his main protective detail went with him. Most staffers had gone home. The guy got just inside the outer doors, where there is a security checkpoint, before he was tackled.

The Secret Service made the right choice not shooting the intruder dead on the lawn. They certainly had the capability to kill him. They would have been heavily criticized, with pictures of the dead body on national TV.

On September 12, a man wearing a Pokemon hat and carrying a stuffed animal jumped the White House fence. He was tackled and arrested. Should he have been killed?

Comment Re:Comparable? Not really. (Score 4, Informative) 126

When someone buys a share in Apple, they actually get an ownership share in Apple.

Apple, yes. Google or Facebook, no. Google and Facebook have two classes of stock. The class with all the voting rights is in both cases controlled by the founders. The publicly traded shares cannot outvote them, even if someone bought all of them.

Until recently, multiple classes of stock were prohibited for NYSE-listed companies, which tended to discourage doing this. (The classic exception was Ford, which has two classes of stock, the voting shares controlled by the Ford family. This predates that NYSE rule.)

This matters when the insiders make a big mistake and the stock starts going down. There's no way to kick them out.

Comment Crash not computer-related (Score 5, Informative) 179

The Red Line crash was not computer-related. The signalling system for the Washington Metro is a classic electromechanical relay-based system. Just like the New York subways. The Red Line crash was caused by a failure of a track circuit for detecting trains, trackside equipment using an audio-frequency signal sent through the rails and shorted to the other rail by the train's wheels. All those components are pre-computer technology.

As with most railway systems, manual driving isn't enough to prevent collisions, because stopping distances are often longer than visual distances. That was the case here.

The Washington Metro had been sloppy about maintenance of trackside equipment. They do have a central computer system, and it logs what the relay-based signal systems are doing, although it can't override them. They had logs of previous failures, and should have fixed the problem.

Comment Re:White House (Score 2) 138

the US Government use UCAVs to keep the airspace around DC clear.

Actually, the current response to airspace incursions in the DC area is an F-16 and a Coast Guard helicopter. The F-16 is in case it turns out to be hostile, and the Coast Guard helicopter is for the usual case, which is a clueless VFR pilot who needs directions. This happens several times a week. The FAA now insists that all pilots operating within 60 miles of DC (actually 60NM of the DCA VOR) take this online course. Amazingly, there are still clueless pilots wandering into this airspace, although fewer than a few years ago.

Comment Some info seems bogus (Score 1) 408

Some of that info seems bogus. 10,000 CNC mills? Unlikely. 10,000 CNC machines of all types across all of Apple manufacturing, maybe.

There's a nice video about how Apple machines a round can for their round desktop computer. They're going through a lot of steps to make a can, yet they're doing it in a low-volume way. Here's how soft drink cans are made. Same shape, but much higher production volume.

Apple is doing this to justify charging $2700 for an x86-64 machine with midrange specs.

Comment Re:Google's storage (Score 4, Interesting) 408

There are amusing efforts to sell disk drives to Google. Near Google HQ there is a movie theater complex. I once saw an ad run before a movie. Two minutes of sales pitch for bulk purchases of enterprise hard drives, with lots of technical detail. Clearly this was addressed to a very specific audience.

Comment Re:Change Jobs (Score 1) 275

It really depends on management style.

In democratic management styles, then what you said is correct. The manager is just a conduit for information.

But in authoritarian management or top down management, which is having an alpha male (or female) with a lot of talent and ego calling the shots and making the big decisions really works well when it works (and fails catastrophically when it fails). In this style of management, professional skills in whatever it is that the team is doing, which means technical skills in development teams, towers above management or interpersonal skills in important towards the success or failure of the team. Someone with good technical skills tends to make good decisions and someone with bad technical skills makes bad decisions. You cannot build success around bad decisions. Beyond that, the only thing really useful is a bit of charisma to keep the team happy and the ability to get most of one's meaning across. Mostly one just has to be 70% understood anyway, since a bit more latitude in interpreting orders is only going to be a good thing in giving workers room to move.

I've found, especially in Asia where a more paternalistic style is favoured, the outcome of a project is especially determined by the technical skills of a manager and little else. Guys who get into little fights, throw temper tantrums and rarely get their meaning across, but make good decisions tend to have better success than good communicators who don't quite understand the problem at hand.

Comment Re:The over-65's swung it for No (Score 2) 474

Ouch. I've seen quite a few family breakup analogies, but this is the first time I saw Scotland be the child instead of the spouse.

If we're going analogise a country to a person, actually I'd say it's pretty natural to seek out unions even though they involve giving up some independence. That's why people get married. That's why the EU keeps growing. Even the most perfect couples don't always agree all the time, but they find ways to figure it out because it's better together than apart. Divorces are universally considered a tragedy in our culture exactly because we recognise that unions bring strength: when one partner stumbles, the other is there to help.

Salmond's behaviour with Scotland has been like going to a wife in a working marriage where decisions are taken together and telling her constantly, repeatedly, that she's too good for the man she's with. That her husband treats her unfairly. That she's oppressed by him. That everything wrong in her life is her husbands fault. She didn't get the promotion she wanted? Husband's fault. She doesn't get enough attention? Husband's fault. She can't afford the clothes she wants? Husband's fault. He's just so unfair. How could she not be better off without him? She's strong and pure and good and she needs to break up with this loser.

Oh, the husband objects? He doesn't want a divorce? That's just bullying. He's promising to give her more say? It's just lies. He's asking how she'll pay the rent without him? Scaremongering. Of course you can pay the rent. Sure you may not earn enough to pay all the bills each month and you've both been relying on the credit card, but selling off the family silver will take care of that.

I could go on but you get the idea. The ultimate legacy of Salmond's failed campaign is that a significant chunk of the Scottish population has bought into the idea that they're somehow superior or morally better than the emotionally deformed English, whereas such feelings were not previously widespread. This is a toxic legacy that could take generations to resolve. It will certainly not make anything easier in future.
