    There is nothing to stop my neighbors from doing installing solar also - and several have.

    Do householders thank their neighbors for the break they get on their mortgage interest that allows them to afford their houses?
    Do the various fossil fuel industries thank every tax payer for the huge subsidies that they receive?
    Do farmers thank everyone for their subsidies that permits them to grow crops like tobacco that kill tax payers?

    Out of curiosity, what was the pre-subsidy and tax incentive cost, or alternatively what were those subsidies/taxes?

    The installation is rated at 8.9 kW DC (7.5 kW AC) and the total cost was $65,000. I received a check from the state of California for $29,000 and a tax credit of $5,000. So my out-of-pocket cost was $31,000 . All numbers rounded and in 2003 dollars.

    Will home insurance cover these panels in the event of hail and wind damage?

    I don't know. I didn't think to ask as I haven't ever seen a hail storm here and we don't get very high winds. However, chemically strengthened glass is used for the panels so they are less likely to be damaged compared to float glass. The panels are solidly anchored to the rafters and the roof is metal tiles so they aren't likely to blow away.

    I did check that everything is covered for theft or fire damage as the inverters were quite expensive back then.

    Solar energy provides all the electricity for my house, and has done so since 2003. Not a single electricity bill since that time.

    I installed 48 panels on my roof and I run the air conditioning, washing machine, electric dryer, dishwasher, and everything else electric from the roof panels. We do have gas heating and a gas range. I have a modern thermostat and I set the low point to 72 degrees and the high point to 76 degrees and let the system figure out how to keep the house in that range. I leave it set that way all through the year.

    In the the year before installing the panels I spent $2800 on electricity, and prices have gone up considerably since then. The costs of the installation (after California state subsidy and tax incentives) was $31,000 so I've fully recovered the installations costs. I expect the panels to continue producing all the electricity I need for the next 20 to 30 years.

    Pulling a family off a flight and threatening to summon the police seems pretty intense. They must have done something very bad. What? One of them tweeted about poor customer service before entering the aircraft? That's it?

    Did the SWA agent seriously think that threatening the family with not being able to fly and reporting the man to the police (for what?) unless he deleted the tweet would be the end of it? Did the agent think the whole thing would be erased from everyone's memory and it would be as if nobody complained? That's not the way it works. Now everyone in her management chain knows who she is, and not in a good way. Creating a PR incident like this will not go without notice. It's a variant of the Streisand effect.

    It's not important to the story, but at least one airline I've flown has figured out that it's good customer service to allow people who spend a lot of money travelling on their airline have their children treated to the same boarding privilege - especially as it costs the airline nothing to do so.

    The GOP has made it very, very clear that anything that Obama favors will automatically receive a negative from the House of Representatives that they control. They have done this multiple times. They have openly stated that their primary objective is to oppose Obama on everything.

    Now I'm supposed to believe that Obama pressured the GOP to weaken the bill? That seems... laughable. The GOP would never bow to Obama's requests - they have their image to consider. It seems more likely that the GOP revised the bill because Obama said he supported it in its original form.

    It's also strange that the mainstream press doesn't seem to have picked up on such a monumental achievement by Obama. I'd have expected that any such successful pressure from the White House on the GOP would be a major headline in most newspapers that cover US national politics. But the best we get is a press release from the Center for Democracy and Technology. The EFF also had a press release about the amendments to the bill but they don't suggest that the White House or Obama was generating any pressure for the changes.

On my laptop she knows ho to use the trackpad and left-click on buttons. I have no idea where she will be computer-wise by the time she's in first grade, but one thing seems sure, she will know how to use one.

  14. I've been programming for 45 years on Ask Slashdot: Can an Old Programmer Learn New Tricks? · · Score: 1

    I started programming professionally in 1969 with Fortran, followed by COBOL in 1970, Algol and IBM 360 Assembler in 1972. Since then I've coded projects in Basic, Simula, ESPOL, NDL, Databus, PL/1, PL/S, Rexx, Forth, Pascal, and half a dozen different assembler languages such as 6502, 6800, 68000, x86, Datapoint, PDP-11 and PowerPC. My current languages of choice are C, C++, C#, and JavaScript, although I can do Transact/SQL, Visual Basic, and Python if needed.

    Here's my point. A computer language is just a way of expressing simple commands. The concepts are pretty much the same across most procedural languages. A DO loop is a DO loop, regardless of what you call it and the exact syntax. A much bigger issue is learning the idioms and the libraries associated with each implementation of a language. Just like human languages, the more of them you know, the easier it is to pick up the next one.

    I've never had any formal computer classes. Back when I started there was no such thing as a computer science degree - most university classes in computing were done the math department. But you still have to learn. Buy books, read them, do small projects to familiarize yourself with the languages. Make yourself learn. It's your career, manage it. Make certain you have the skills that are needed, and if you think you don't have the skills you need then be proactive in getting them. Use the Tiobe index to see what's trending up.

Computers are easier to handle than people - they don't lie, they do what you tell them, and they don't have hidden agendas, and they don't backstab.

    In the USA there is a constitutional right against self incrimination, and the right not to answer questions from the police has been the subject of many movies, both fictional and non-fictional. It's generally considered that "taking the fifth" is a well known act by criminals.

    Without doubt it is possible to argue that not answering questions is impeding an investigation and therefore obstructing justice, but it is balanced by a suspect's right to remain silent when questioned by police. Now whether a person can be compelled to answer questions about a password is a different twist on the question "where did you hide the key the safe" or whatever, but I think the answer is well settled in U.S. jurisprudence.

I used a SuperMicro motherboard, a similar Xeon 6-core CPU, 128 GB of ECC RAM, two Samsung 512 GB Pro SSDs (primary and a local backup), and an NVIDIA Quadro GPU. All the other components (case, power supply, CPU cooler, fans) are top quality. My supplier ordered the parts and charged $100 to assemble and test it. The user is running Linux and he's happy with the system - happy enough that he's demoed it around his department and says it has generated much interest. In any case, a new Mac Pro wasn't an option for him as he's using CUDA rather than OpenCL.

    The total cost was $4,150. The system has twice as much RAM as the Mac Pro supports, an upgradeable GPU, space for many more drives in the box, and a savings of about $1,500 over an equivalent Mac Pro with 64GB RAM. OK, the box doesn't look as nice, but since it's under the user's desk that's not so terrible.

    The cost saving is not the biggest improvement over the Mac Pro. The big items are having an upgradeable GPU and expandability inside the box - Thunderbolt just doesn't have the product base yet. I'm beginning to doubt it ever will with higher speed USB in the pipeline.

Code gets old and has to be updated, and there's a ton of work that doesn't require the brightest and best but still has to be done.

    Now the grade A people don't want to know that. They want to work on the sexy new stuff that makes them look like the superstars they are. They might put up with maintenance coding for a while, but they won't stay there. They will want to move to better things, and if they can't they will move to another company - and because they are grade A, they can do that with relative ease.

    Google used to have the same issue with a grade A requirement, and they found that products stayed in beta for years as a result of engineers moving on when the interesting parts of the code was done. They even had to cancel some products because they couldn't get engineering resources that wanted to work on them. So they lowered their standards a little and things improved somewhat.

    By the way, I'm not knocking maintenance programming - that's often difficult work. Maintenance guys have to come up to speed quickly on systems they never wrote and then make the code do things it was never designed to do, and finish it in an impossible short deadline, because it's "only" maintenance.
