We are beginning to design stuff into cars which continuously draws power, much like the numerous things in our homes that never turn completely off.
Solar cells built into car windshields can be used to mitigate the effects of a car not having its engine running. An owner of a solar-cell windshield equipped car will be able to return to his car, parked at an airport after it has sat unused for possibly several weeks, and have the battery fully charged upon his return. I have traveled and it has always been a concern to me whether the car will start after I have ignored it for a week.
Just a few hundred milliamperes going into the battery would have mitigated this concern.
I do agree with the posters who have already pointed out that using this for office building windows is a lot of wasted expensive effort for a negligible ( and likely negative sans tax credits ) return on investment, considering the cost of line power. A car in a parking lot usually has no line power available.

Sorry, couldn't resist.
The PC is dead, as you gloriously noted at SXSWi this year. Michael Dell is now officially back at the helm.
What is your advice to Michael Dell?
What California needs right now - more than anything else - are companies who are funneling money into paychecks and will provide the State with a database of who is getting paid, and how much.
Do not kill the goose which is trying to lay a golden egg. Sure, you can kill the goose with tax law, but in doing so, you forfeit all those eggs it was going to lay.
The streets of California are already littered with the carcasses of killed geese.
Many done in by the pen of the FTB. The parts that used to run the goose now are on welfare.
From what I can see, all this economic malaise we have had is a result of both poorly applied taxation and mismanagement of resources. We tax productivity and reward sheer gluttony/greed. So far, the FED has kept the economy "growing" by dropping interest rates over the last 30 years or so. For 30 years, the FED has been able to keep dropping the interest rates to keep liquidity in the economy so merchants could brag around 10% year-over-year growth in sales receipts, making their stock look good, as well as real-estate people carrying on over increases in home price. By lowering interest rates, bankers have been able to support increasing home price - but look at the charts.... how much leeway do the bankers have to keep this charade going?
Look what happened the last time Bernake bumped the rate up a bit. Google found lots of charts. They all say the same thing. Our economic engine is now running on fumes.
Look at the charts. This cannot go on much longer. We are now at the end of travel. The wolf is nearing the door, and we have outsourced way too much of the vital resources which kept our USA strong. The global elite will fare well, unless riots take them out. The rest of us are kinda caught in the mess.
The debt owned by the public equates to 12 trillion which is something I'd call huge.
Interestingly, U.S. household wealth topped $74.8 trillion this year, making you wonder if those debt hawks are squawking about a problem that's not as bad as it sounds out of context.
Not sure why you're not interested in Uverse if it's available. Are the Internet-only plans there unreasonably priced?
No. In my case, it's trying to apply the
I used to think it was because it needed a bunch of temporary disk space, so last night I changed the TMP and TEMP environment variables to point to a volume with tons of free space, rebooted (because, you know, it's Windows), set just one of the several
Honestly, I don't know why anyone continues to be surprised by Redmond's rank incompetence...
Right now, the banker-boys net the profit from issuing currency that the Government should have been getting.
Where does this increase in money supply come from? For you and me, we have to earn it, but if I go to the bank for a loan, where do they get it? Thanks to something called the "Fractional banking system", they can just enter my debt to them in a ledger and start charging me interest for the loan of something they never had in the first place. The usury will now require yet another loan somewhere to pay that back.
This whole banking scheme is a huge moneymaker, yet the government would rather tax the working stiff on his wage rather than covering the costs of running a government by the increase of the money supply.
In my house I use the right bulb for the right purpose. Bathrooms and closets get incandescents
For me, it has to be incandescent for the bathroom. Condensation is a problem. I need the heat of the incandescent to insure the water does not accumulate in the fixture and make both an electrocution and fire hazard.
Note to "Relion Group"... I have seen numerous advertisements of yours advising anyone taking some drug that had an unintentional side effect to call you and your attorneys will sue the hell out of the manufacturer. Can you please start running ads to the effect that if you have had a house fire or electrocution due to condensation in an electrical fixture designed for incandescent but retrofitted with a bulb it was not designed for to personally sue those Congressmen that voted this requirement into law?
So far I have had three CCFL retrofits fail from failure, what appeared to be a voltage spike damaging either one of the input diodes or one of the two inverter transistors, or the noise spike may have buggered the timing of the inverter to the point the ballast inductor saturated with the resultant current spike doing the damage. In all cases, the device failed shorted, and the resultant current surge caused a brief flash of fire to escape the enclosure, evidenced by the carbonized area around the blown devices. I will not have those halogen rod lights in the house for the same reason. You can place a flammable near one and ignite it.
Many of the LED offerings available have poor heat sink design, which becomes apparent once you install the thing.
The saving grace of the old incandescent is when it quit working, it simply quit. And there wasn't much way for the fire to get out of the bulb unless you physically broke the bulb.
Not to say I am against LED or CCFL altogether. I have retrofitted a lot of fixtures to use 100 watt ( yes, 100 watt ) LED chips, albeit I only run them around 20 watts or so, and get lots of light. If your LED is running too hot to hold, its running too hot. I ended up making quite a few of my fixtures using old aluminum cooking utensils - they were thick, had good thermal heat sinking properties, and were cheap at garage sales and thrift stores.. thick aluminum ashtrays/bowls work nice. LED's give you a lot of artistic freedom to work with various colors and extremely simple dimmer circuits, as well as being quite safe due to their much lower operating voltages. The commercial offerings are pricey right now, but if you care to get the guts and roll your own, you can be quite free to express your artistic side and make something unusual.
Build it right, don't overdrive it, and the LED should last longer than you will.
So far, I have had extremely positive results from my efforts in building LED's into my stuff. I highly recommend both the 100-watt chips I linked to ( but running them substantially less than that ). Ten watt chips using similar mounting methods are also available, and run very well from current-limited 12 volt sources. ( I run my 10 watt ones at about 9 volts/200 mA or so... about 2 watts or so each ). I have already seen lumen degradation and chip failure of devices run full power, so I don't do that. Those things are rated for excellent heat sink design, which I have yet to achieve.
This is only the US version. Canada Post's "super mail" boxes only require one key. You use it, and return it to the outgoing mail slot.
- ZFS's design requires RAM to be perfectly reliable, or at least report imperfections. Undetected bitrot in RAM can and will destroy your entire ZFS pool. Thus, a machine with ECC RAM installed is a requirement.
- As if that weren't enough, ZFS eats huge amounts of RAM. The current guideline is 1 GiB of RAM per TB of disk spindles, with 8 GiB as a practical minimum.
- ZFS assumes it has perfect knowledge of disk writes in-flight, and as such doesn't play well with RAID controllers, which can silently re-order writes. If your machine has a RAID controller, the RAID features should be turned off. Don't worry, ZFS has its own RAID features. However:
- Because drive densities are now approaching drive error rates (10**13 bits of storage, with manufacturers quoting uncorrectable errors every 10**14 bits read), ZFS RAID-Z1 is no longer considered sufficient to ensure storage integrity, and you should plan for RAID-Z2 (two parity drives).
- For the same reason as turning off RAID, a "production" FreeNAS/ZFS installation should not be run in a virtual machine. It's okay if you're just test-driving it to get a sense of what it can do, but a live system should run on actual hardware.
- Using ZFS's de-duplication feature is officially discouraged. It may seem like a great idea, but it will gobble all your RAM and return very little benefit. On average, you're better off using compression.
When ZFS dies, it dies in a big and fairly comprehensive way, and ZFS will die if you under-provide it. In any event, you should RTFM before contemplating a build, and know the trade-offs you're getting in to.
My conjecture is that the industry as a whole is saturating, and people fortunate enough to have landed the higher echelons in companies are doing the animal-planet alpha-male thing and running anyone possibly more technically competent than themselves out of the company while they still have the power to do so.
I am handling it by developing independent products and working with small companies, as my hope for ever working for a big company again is dashed. I can not imagine a company that has the financial resources to hire expensive lawyers and managers has any place for artistic types. I consider myself to be one of the dime-a-dozen gardeners in their eyes. A "computer janitor" as one of my fellow slashdotters noted so eloquently.
We have got tax and business law so convoluted with special interests that actually doing anything makes little business sense, when there is far more money to be made by throttling competition and selling rights to do anything. I see this going on and on and on as long as the world relies on the US as their bank, as it is well known that bankers eventually end up owning everything due to their capability of not only creating currency out of thin air, but also expecting usury on it that can only be met by their printing yet more currency to pay the amount owed.
History shows only one way has worked to reset the system, and it ain't pretty. Civilizations have worked just like a relaxation oscillator ( avalanche mode ) for as long as we have recorded history. No reason it stops now. It is not human nature at all for it to stop.
I don't have time to correct all the errors in the parent post. So very briefly:
- The 6502 had three 8-bit registers: A, X, and Y. A was the accumulator, and received the result of all arithmetic operations. X and Y could hold temporary data, arithmetic operands, and be used as index registers for memory load/store. There was also an 8-bit stack pointer register, SP, hard-mapped to the range 0x0100 - 0x01FF.
- The 8080 had the 8-bit registers A, B, C, D, E, H, L, and a 16-bit stack pointer. In addition, the registers B & C, D & E, and H & L could be used to hold 16-bit quantities for some instructions.
- The Z80 had all the registers of the 8080, plus a shadow copy of the registers for quick use by interrupt service routines.
- The 6502's zero page (0x0000 - 0x00FF) got special treatment by the CPU, using only a single byte to address a location. As such, zero page usually got treated by software as a pile of "slow registers."
- No instruction on the 6502 executed in fewer than two clock cycles. The fastest 6502 I ever saw was 2 MHz.
- By contrast, 4 Mhz Z80 chips were widespread.
- The Z80 helped popularize dynamic RAMs by containing a very basic DRAM refresh counter. The 6502 had no such thing; DRAM refresh was usually provided by custom logic, usually part of the video controller.
- S-100 machines had huge power supplies because they had huge numbers of slots (eight or more being common), and had to have enough reserve power for all of them.
- There was nothing special about the 6502's memory access patterns, and 6502 would get starved out like any other CPU if another device held the bus. On the C-64 in particular, every eight video lines, the VIC would grab the bus for 40 uSecs to fetch the next row of character cells, holding off the 6502 the whole time. This led to all kinds of problems with timing-sensitive operations, and was directly responsible for transfers to/from the 1541 floppy drive to be glacially slow.
In general, it is bad form to peek under the sheets in the database. However, it could be extremely useful to tie a trigger to a primary key + address for these specific cases. The database should also not block on it if there is no DML or DDL going on -- just piping to a message queue or executing an external script or whatever.
Blue-skying. It's still early, here.
