    There is generally FEMA funding available for burying wires.

    Every time a hurricane hits St. Croix (U.S. Virgin Islands - an unincorporated U.S. Territory), they allocate funding for burying the wires. 80% of it finds its way into various pockets, and the 20% left over goes to balancing the wires back up on poles for the next hurricane.

  6. Aren't smart meters more about differential rates? on Ask Slashdot: Are Smart Meters Safe? · · Score: 1

    Aren't smart meters more about differential rates?

    It seems to me that the power companies are deathly afraid of losing their stranglehold on energy, so with all the government subsidized solar coming on line in California, and the forced-buy by the power company, the point of smart meters seems intended to be poised to implement an arbitrage system in order to game the power rates.

    With an ordinary meter, if you provide power to the grid, the meter runs backwards: they pay you the same rate as you pay them, at least for power you "borrowed" during the night. But what if they could pay you less for the power you provide them than they charge for the power they provide you? Smart meters enable this business model and protect their monopolies.

    Personally, I think the grid should be government owned and tax supported, and that power companies should have to pay to lease it. For the case of municipal power companies, to avoid establishing vertical monopolies and integration, they'd have to divest their generating capacity, but that's a small minority situation with power generation in the U.S..

  10. Adopt good developer tools, process on Ask Slashdot: What Defines Good Developer Culture? · · Score: 4, Insightful

    Good developer tools make all the difference. They get the hell out of the way of doing work.

    (1) The biggest thing you can do to make people happy is fast builds. That generally means rolling your own, since tools like emerge/ebuilds and so on all have horrendous overhead. A null build of a product containing 500 modules (for example, an embedded Linux device) should take no more than 10 seconds. If it takes more than 10 seconds to do nothing, then you are doing it wrong.

    (2) The next biggest thing you can do is proper build. Building is half the battle; the big thing that stops work is integration failure. Say you have 500 packages in a product, and you make a change to one of the packages; what should get rebuilt? The answer should be (A) the package itself, and (B) whatever depends on APIs exported by the package. Yes, this means properly expressing dependencies. This is hard. Boo hoo: you are getting paid because you do hard things that you ordinarily wouldn't do, except if you were getting paid. Get the hell over it. Doing things this way is incredibly important in order to resolve #1: If I can use binary build products for all the packages I'm not working on, obtained from a previous build, then all I have to concentrate on building is the things I'm currently working on. A 30 minute build goes down to a few seconds.

    (3) This is necessary to resolving the build: Have strong inter-module contracts. A package that exports an ABI used by one or more other packages should damn well export a linkable library and header files. If the library version doesn't change, and the header files haven't changed, you don't need to rebuild the damn thing. But this can only be properly known if you have partitioned your packages such that they export ABIs. The ABIs should be documented, and these documents are contracts, where you agree not to break the contract from either end of things. A dependent package needs a new API? That's a negotiation. A Package wants to deprecate an API it exports? That's a negotiation, too.

    (4) After build works, you need integration. Integration boils down to using branch tags in your source code control system. This is necessary when someone attempts to submit a change that breaks things: instead of being dead in the water until the change is fixed or reverted within the package, and waiting hours, the B&I team reverts the package version to the previous version, and you are good to go: Things take minutes, not hours, days, or weeks to resolve. The B&I team is God, but their deliverable is binary packages. This is important in support of #1.

    (5) React appropriately when things go wrong. For example, if someone commits a test that's broken, but the test isn't exercised, and three weeks later the code path gets activated by a change and breaks things, do the right thing. The right thing is to back the hell out the change that activated the code path. The wrong thing is to try to fix the test at that point, while everything stays broken on the theory "Ah, this is a smiple fix, I'll just fix the test instead". You may look like a hero for fixing the test after a couple days or a week, but you aren't, you're the bottleneck who killed the productivity of the rest of the team while you were trying to fix the test. Bottom line: back out the proximal cause of the problem, and fix the root/distal problem out of band. Everyone gets to get more work done.

    (6) Test appropriately. This is almost never done; most testing is reactive. What I mean by this is that people tend to write tests to verify that things are fixed, and then integrate those tests into their waterfall; that's a reactive test. This is almost never useful, since it doesn't verify correct behaviour, it only protects against regressions on a bug that was noteworthy enough that it's unlikely to repeat. Instead, testing should test desired product functionality. One aspect of agile programming that is a good idea is writing the functional tests before writing the code.

  11. Spoofing GPS is useless on GPS Spoofing Attack Hacks Drones · · Score: 1

    It's useless to spoof the GPS signal unless you know, apriori, where the drone is going. Lying to it about where it is is only useful if you lie to it relative to its destination, unless you are trying to lie it into a target very near the jamming signal source.

    The Iranian spoof worked because the self destruct wasn't armed, and when jammed, the drone was known to be programmed to return to its launch site, which was a known location, and THAT location could be spoofed.

    I imagine that there were a number of experiments in jamming to see what the behaviour of the drone would be when its communications were jammed, and the first several probably had armed self destructs and just blew themselves up. Given that these things are somewhat expensive, they probably stopped arming the destruct, which prevented the jamming from being used as a remote "blow the drone up" trigger. And then after a couple of them returned to base, and it became SOP to not arm the self destruct, the spoofing started, resulting in the drone capture.

  12. Not that new an idea on Army Creates a Directed Lightning Bolt Weapon · · Score: 1

    The Air Force had a similar weapon in 1978, albeit using what was effectively ball lightning in the plasma channel rather than full arc charges like the Army weapon -- I don't think the arc charges terrifically useful any more than people die in the Farraday cage at Arc Attack concerts at Maker Faires (hint: they don't).

    The air force work was based on work by Pyotr Kapitsa, the Russian Nobel winning physicist. The idea was to create a plasma channel with a laser, drop a ball of lighning into it, and let the closing channel push it into the target. I'm pretty sure the project was scrapped for the same reason the army project isn't going to go anywhere (unless they deploy it against combat troops, rather than vehicles.

    HERF guns would probably be more fruitful, if the intent wasn't fried humans; at least HERF guns actually work against avionics/vehicle electronics.

  14. You're making another error on Dr. Dobb's 2012 Salary Survey · · Score: 1

    Benefiting the citizenry is not the same thing as benefiting society, and the point of services provided by society needs to be to benefit the society, not the individual. If it benefits the citizenry as well, that's a nice side effect, but it should not be the primary underlying goal.

    Setting the price point at or lower than the necessary price point to achieve the societal benefit is all that's necessary. In the case of higher education, this is achievable at a non-zero price point. And yes, this means that some people will be economically disadvantaged by that decision.

    I would argue that it's possible to be a member of an economic underclass and get a scholarship for your higher education. I know many existence proofs. So the corollary to that is that setting a non-zero price point only economically disadvantage those who are already intellectually disadvantaged to the point of not being able to obtain said scholarship.

    Again, we get a net benefit to society: the people who can afford the economic admission get it, and the people who can't afford that admission, but who can instead afford the intellectual admission instead, both get their higher education.

    While it could be argued that the net benefit to society would be higher if it were a pure intellectual meritocracy as to who received the education, until you hit the net benefit cut-off point, the ability of institutions to float scholarships on the backs of less intellectually gifted people with money to spare is very similar to achieving the same ends through taxation. This method, however, avoids the negative reaction you would get by taxing the parents of less capable economically advantaged students, and then not letting them into the club while using that money to pay for the economically disadvantaged geniuses.

  16. Studying doesn't make you more intelligent on Dr. Dobb's 2012 Salary Survey · · Score: 2

    You're an idiot for comparing "Feasible" with "Free", he's saying- It's a birth right, you're saying if you work yourself to death doing odd work during the years of your life you're supposed to spend studying to become more intelligent and an eventual net gain to your family and country you might just get one.

    Studying doesn't make you more intelligent, it makes you more educated. This is fundamental attribution error often seen in highly educated people who like to believe themselves more intelligent for it.

    You tell me which one's better- yes yours works, but it doesn't even compare. So don't compare them. People always bring up your point when the free things other countries provide are mentioned, and it's just stupid.

    I agree that education up to a certain level should be considered a birthright, but you quickly hit a point of diminishing returns when you attempt to educate everyone to the same level. Some people are in fact not educable -- this is the major legitimate complaint about the "No Child Left Behind" policies of recent decades. Not everyone is capable of having differential calculus crammed between their ears.

    You also hit that point when you start educating people in fields which were self-selected based on their expectation of income. Does the U.S. seriously need more lawyers per capita than all other countries (25% higher than Brazil, the next most lawyer-heavy country)? Probably not. Does it need deeply unhappy brain surgeons who are only in it because of the money? That's probably counter-productive as well.

    Frankly, we don't need the number of people we have in order to maintain society at the current level, and we will likely need to come to terms with finding some way of giving them money not to steal our stuff at the point we realize cable television is no longer cutting it.

    Pick something as far from programming as possible, and do that.

    I was convinced from a very early age that I wanted to be a nuclear physicist (this was back before it was politically corrected into "high energy physics"). I learned everything I could about it, learned all the math, derived neutron numbers from information gleaned from "The Curve of Binding Energy", and basically absorbed information like a sponge.

    Then I went to my first year of college (entering as a sophomore due to my AP credits), did well in the first couple of quarters of physic classes (started in at the junior level, since I was pretty advanced in physics already), and things were going great. Then I was visiting a lab, and saw my first microcomputer with a graphics card (a Terak 8510, as it turned out).

    Now I'm a software engineer for Google, having worked previously for Apple and IBM.

    I tripled in physics, math, and CS, and physics taught me an incredible amount about how to think about problem solving that I couldn't have achieved without studying an actual hard science, but I'm not working in the field by building bombs for TRW to balance on top of pencils of fire.

    The point of this little autobiographical journey is that, even if you know what you want, you might not know what you want /more/, until you encounter it.

    So set yourself up in a situation where you'll encounter something outside your comfort zone, and which is far away from your experience to date. You might find you hate it; you might find you love it, but either way, in doing that, you'll find out more about yourself and the world. And if you find something you hate, remember that you can do something you hate while looking for something else; a summer is long enough to sample up to half a dozen things you find that you hate.

    If I had my summer between high school and college to do over, I'd probably try for the news room at a newspaper, an art studio co-op, a cruise ship, a CPA firm, a law firm, an airline, or randomly opening the yellow pages.
