Comment Re:What about ... (Score 1) 170

Serious? No. I don't seriously expect really safe speed limits to be set up by any democracy that has so many motorists in it. But I do think that's what we ought to do. As a civilisation, we are killing our own children at an appalling rate, just so that motorists can catch up to the back of the next long line of stationary traffic a few seconds faster. In town, slow down.

Look at the scenario you described. A car doing the speed limit towards a marked crosswalk... it's such a familiar scenario that we forget to be horrified. Think about what we're doing here. We have footpaths across the street specifically for people to walk across. And then we have motorists driving straight at those footpaths, at such speed that it would literally be a crime to go any faster at all, at such speed that they couldn't possibly stop should anyone suddenly walk out on the path. These motorists expect everyone else in the world to pay attention, to stay out of their way. God forbid they themselves should slow down! They're 'doing the limit' and that makes it OK.

That limit is obviously much too high. It should come down. Twenty is plenty.

Then let's redesign those footpaths. At the moment there are raised paths either side of the street, and when the path runs across the middle of the street it is lowered. For the convenience of motorists, of course; otherwise they might have to slow down. Well, let them slow down! The path across the street is a pedestrian walkway just like the paths either side, so let's have it at the same height, for the convenience of people using wheelchairs, people pushing infants in prams, people with mobility issues. We'll put a gentle slope to either side of the path so that it isn't a nasty bump for motor traffic. Well, I mean - so that it isn't a nasty bump if the motor traffic is moving at a safe speed.

Yeah, speed limits are definitely way too high, you're right about that. 20mph in cities is plenty. Then you have a lot longer in which to notice people walking across the road, your brakes have much less work to do in order to bring the vehicle safely to a stop, and if you still fail to respond in time you'll do much less bodily harm to somebody.

Comment Clever, but not that useful in practice (Score 1) 55

91% success is impressive performance, but it maybe isn't that useful for, eg, spotting suspects on CCTV footage. For example, the London Underground carries nearly 5 million passenger journeys per day. 9% of that is 450,000. So, if we are talking false positives, nearly half a million non-suspects for humans to check every day. To put it another way, it's several non-suspects to check in every single carriage of every single train during peak times. This is why global surveillance often isn't a very good way to catch the bad guys.

Report: US Government Worse Than All Major Industries On Cyber Security (reuters.com) 124

schwit1 quotes a report from Reuters: U.S. federal, state and local government agencies rank in last place in cyber security when compared against 17 major private industries, including transportation, retail and healthcare, according to a new report released Thursday. The analysis, from venture-backed security risk benchmarking startup SecurityScorecard, measured the relative security health of government and industries across 10 categories, including vulnerability to malware infections, exposure rates of passwords and susceptibility to social engineering, such as an employee using corporate account information on a public social network. Educations, telecommunications and pharmaceutical industries also ranked low, the report found. Information services, construction, food and technology were among the top performers. And we are supposed to trust them with healthcare? This report comes after President Obama recently unveiled a commission of private, public and academic experts to bolster the U.S. cyber security sector.

Yes. But the technically impossible problems were solved, and it has transformed the way people travel over that particular route. My daughter now takes a train from the South of France to London, non-stop, in only slightly more time (city centre to city centre including check-in) than it would take by plane. And tunnels last for quite a long time, so it makes sense to take the long-term view.

Comment On the other hand (Score 5, Informative) 342

The article sounds remarkably like the articles written when the Anglo-French Channel Tunnel project was proposed. Various aspects of the project were allegedly impossible when digging began, including concerns about the nature of the rock under the Channel and that the air in the tunnels would overheat because of the absence of ventilation tunnels under the sea. The project did run over-budget, but it worked, and is still working, and has transformed the way people and freight travel along that route.

Comment Haven't we been here before? (Score 1) 243

All the arguments made for Tizen were made a few years back for Bada, another Samsung "for entry level phones" OS. It worked on a technical level. At one point it was selling reasonably well in some European markets. I have a Bada phone I bought for development. If you're in the US and never saw Bada, it's because it never made it to the US, and now it's history. Really not sure why Tizen is going to fare differently.

Comment C++ is C (Score 1) 641

Modern, best-practice C can be compiled with a C++ compiler. (There are a few gotchas moving in either direction - http://www.cprogramming.com/tu... - but it's not hard to avoid them.) For all its object-oriented impurity and spec-bloat, the one thing I love about C++ is that you can write relatively high-level code when that makes sense, but you always have the option to grapple with all the fine detail when that's useful.

Comment H1B applicants are people too (Score 5, Insightful) 190

The article doesn't seem to point out the obvious explanation, ie that H1B applications contain personal data (of the type Slashdotters are usually passionate about protecting), and that it is good practice not to keep such information hanging around once it has served its primary purpose. There are presumably solutions to the research concerns, such as aggregating the data before it is deleted or collecting the specific data necessary before the records are deleted.
