    You don't blow up threatening space objects. Space is really big. All you do is give the object a little nudge while it's still far enough away.

    Of course a "little nudge" is relative if you're talking objects of any serious consequence. A 100m asteroid - a decently sized H-bomb on impact - is likely to weigh >1,000,000 kg. That's a lot of inertia to nudge even a little bit. The smallest ones (<15m) we don't need to do something about, the biggest ones we can't do anything about (the dino killer was a trillion tons) so there's a few in the middle that we maybe could, but statistically it's like an entire city struck by lightning - nasty death from above for those it happen to, not really a threat to the human race.

AMD is being a giant cocktease, first they flash a picture, then they give us some speeches and marketing slides, with the promise that they're oh so worth waiting for. Meanwhile nVidia is putting it out there saying if you want it, come get it. I don't think this "hard to get" strategy is working out to AMDs advantage, I'm sure a lot of people are tired of getting stringed along.

    In high end CPUs it's been years with no real acknowledgement from AMD that Bulldozer was dead, they're going to string you along as long as possible in the hope that maybe you haven't gone Intel/nVidia by the time they get the product out the door. But their credibility is wearing extremely thin, you know they have review samples ready if they're about to launch the product. That they don't want the facts out there speaks volumes that the facts are against them and the fanboy hype will turn into a backlash when they don't live up to the wishful thinking.

  6. Re:The root cause : poor unit testing on Report: Aging Java Components To Blame For Massively Buggy Open-Source Software · · Score: 1

    No, the problem is that you got no knowledge or control over the quality of work done on the component. There are lots of ways to subtly break it through failing on a particular set of inputs or a particular sequence of events that is combinatoric in nature and essentially impossible to predict. For example imagine you have functions a() through z() and it'll crash if you call c() after g() unless you've called v() in between. How can you unit test for that? You can't. What if the new component has a threading bug that'll only show up one in a hundred runs under heavy load?

    Of course, if they have proper unit tests it shouldn't start regressing and breaking in surprising ways. That's a pretty big if. And it really only needs to happen once before you and your manager get chewed out for breaking the system just to keep up with the bleeding edge. It's pretty hard to argue against code that has withstood the test of time, as long as none of the flaws and limitations seem to matter to you. I know that happens to some code I run into, it's ugly as sin but it actually works and I just pray I don't ever have to debug it.

    More like muscles are high upkeep so you have to exercise to keep them, if you just asked a muscular guy to not exercise he wouldn't lose much weight. In fact unless he adjusted his eating habits he'd be a lot more likely to gain weight. And if you reward yourself with junk food and snacks after exercise it won't do you any good at all. There's three very good effects though:

    1) If you're already on a healthy diet it's easier to exercise more than reduce intake even further.
    2) The ratio of muscles to fat is improved, giving you more strength to carry less.
    3) Muscle is denser, even if you're not lighter you'll be slimmer with less flopping around.

    The first one is as simple that the body needs a good fuel mix, it doesn't work well on pure fat. So you have to eat a minimum and if you eat more and exercise you can burn away the fat portion without undernourishing yourself. The second and third basically makes you feel and look better, which is probably just as much the point as the number on a scale.

Around here it happens rarely as all cables and pipes - not just fiber but electricity, water, sewage etc. are recorded and easily available for anyone else digging. If it does happen whoever broke it pays or if it happens by natural causes it's a running cost built into the monthly subscription.

By 2025 we'll start seeing the first 5g cellular plans they'll offer 1gig+ service for a lower price and using less spectrum than 4g.

They'll get that back with taxes eventually, but it's not clear whether the taxes will be on the locals or Statewide. Assuming a five year note, average household size of four, and the costs paid entirely by the locals, that should about double the $65/month that is the nominal cost of the system.

They're borrowing $3.6 million which works out to $4500/household, but five years is generally too short. Most estimate that a buried fiber will last 30-40 years, if we say 20 years then it's an extra $20/month in taxes. Seems like a fair price, near my cabin they're building out to ~1200 premises for $5.2 million with a mix of government funding and extra sign-up fee, though the most part is covered by the fiber company who'll profit for decades to come. Still, if all goes according to plan I can get gigabit there at the end of the year and "only" 100 Mbit at home...

    It's the thing you don't care much about or that's too big to get first hand knowledge that gets you, not those you actually research. There you pretty much know all the options and what actually fits you, it's when you're feeling a hunger and a burger is good enough the ads kick in.

    We're mostly creatures of habit and just buy whatever we bought last time, advertising and sales go hand in hand to make you try new products. Make lots of people aware that it's a sale, lower the price so they'll try it out and some of those will just keep buying until a different campaign steals them to some other brand. Maybe a few are meticulous but if I got 20-30 things on my grocery list I'm mostly just picking what I'm supposed to buy.

    Same sometimes goes for where to shop, if I know one store that has something that's often enough because I don't need three. It's something rare I'm buying once in forever and it's just not worth the time and effort to find and compare multiple sources.
