I finally determined that it wasn't the programmers that were messed up it was that the pic wouldn't accept a program if the supply voltage was over 4.5 volts, even though it was supposed to work at 5v. What voltage were you using on VPP?
I can't understand why we are still concentrating with disks.... Because they give reasonablly random access (unlike tape) and have a much lower cost per byte of storage than anything solid state. This situation doesn't look like it will change soon.
How much do you have to spend on a flash stick to match the capacity of a DVD? what about to match the capacity of a HD-DVD or blue-ray.
why don't we just concentrate with flash-like storage and design interfaces with higher bandwith? flash is already fast enough for most removable storage applications, its just too expensive for distribution/long term storage of media. Each cell takes at least one transistor and there are many overhead transistors for things like erase and programming control. All theese transistors must be designed on a series of masks which are then used to take a wafer of incredibbly pure silicon through a complex series of steps. Contrast this with hard disks where one head serves an entire platter side.
3 digits are a thousand codes. Say each website allows turns before freezing. Just trying out 200 charities will give them the cvv2. we need public key encryption surely the banks should be able to spot such attempts to brute force the ccv2 number.
why can't the IDE intelligently wrap it for us, maybe i'm weired but I hate to have statements split accross multiple lines or multiple statements on one line. When you are working (or trying to work) in a one statement per line style then page width limits become about more than just text formatting!
some languages encourage/use in the standard libraries long identifier names and several levels of nesting (e.g. mainform.listbox1.items.delete(mainform.listbox1.i tems.count); ) if you want to keep your statements on one line each then you are likely to find yourself hitting the 80 column barrier quite a lot with such languages. Other languages (particularlly older ones such as plain C) have much shorter typical statements and so an 80 column limit really isn't a problem.
Afaict phones are locked to a network not a particular account, presumablly apple will just say it was advertised as working on AT&T and still works if you drop an active AT&T sim in it.
Unlike other phones that have their own custom batteries designed to fit their cases and where that model gets phased out in two years and the replacement battery supply ends? i can still get batteries for my nokia 8210 pretty easilly and thats a lot more than a couple of years old.
For business work you pretty much never need something very fast. If all you use your PC for is paper pushing and as a glorified terminal then I agree.
Otoh if you actually use your PC to do actual computing work whether its compiling software, synthesizing vhdl/verilog for fpgas, converting media, running simulations etc then more speed can be very important to you.
i don't see how generating java code is any worse than generating some kind of resourse file. Either way you shouldn't be editing the output file and should only be reading it when things go badly wrong.
OTOH if your gui builder insists on mixing generated code with your own code then i agree it sucks.
hmm do intel have any quad core multiprocessor capable chips in production or do you still need to go to four sockets (read: very expensive case and motherboard) to get 8 cores with an AMD system?
Which is much better than what happens if a person is poor in the US and suffers something like this. they don't get it treated immediately so it gets worse and worse and when they are finally forced into the emergency room they need far more treatment.
Actually no, if you do not have an internet connection viewing webpages is not an issue anyway. I disagree the inability to obtain full installers is going to be a drag for anyone who works on a lot of machines and doesn't have access to either a fast net link or a fast proxy that is likely to already have the files cached from all of them. Some machines may not have internet access but may have access to private intranets. Some (many) machines will have internet connections that require non-trivial download times to install something like IE over the net. Some machines may be used to browse web pages saved to disk and so on.
What we are talking here is the kernel VM which is another option for the VM. Actually stripped down to the bare core so that applets and other applet based solutions are less of a pain installwise. this is a good thing provided they don't make it the only easy option for getting java (like MS did for some versions of IE). Hopefully they won't be that stupid but i wouldn't put it past megacorps
As to TCP over UDP, that's an example of a very bad sounding ideas. I disagree
Redundant features of TCP and UDP. all UDP provides is checksums and application multiplexing. If you really wanted you could tweak the version of TCP you were adapting to run over UDP to remove those features but even if you don't they are very low overhead.
It's not as bad as TCP over IP over PPP over SSH which is over TCP (multiple reliable protocols on top of each other), Yes multiple reliable protocols over each other is generally bad unless they are carefully designed to play nice and there is a good reason for doing it (such as one bad link in the middle of a long chain) but i don't see how that is relavent here.
but still, if you wanted to be a better TCP than TCP, the place to implement would be at the same layer, on top of IP protocol, not on top of UDP. To implement a protocol directly over IP afaict either requires you to use raw sockets or to implement it as part of the OS. The former raises all sorts of privilages/security concerns and the latter requires you to convince all your users to swtich/upgrade thier OS. The hard truth is that for most applications the choice comes down to either take the TCP implementation the OS gives you which may or may not support the latest TCP improvements or build over UDP.
the macbooks hard drive is pretty easy provided you have the right screwdrivers handy. You just remove the battery, remove the HDD/ram shield (three small crosshead screws one of which was unforuntaly overtightened on mine), pull the drive caddy out with a tab and use a suitablly small torx driver to remove the drive from the caddy.
the optical drive in the macbook is pretty burried though and the hard drive in the macbook pro is apparently a bitch to get at.
TCP is a generalist. This is often good it means its well tested but can also mean its not well suited to a specific case. It is also implemented in the network stack. Again this can be a good thing (only one copy of code) but it can also be a bad thing because it means you need to modify the OS if you want to tweak any part of it.
One interesting possibility would be to do TCP over UDP. This would allow you to use the latest TCP tweaks without the need to modify the OS.
The printer manufacturers that don't include this will obviously sell more. "Watch your competitors take suicide: priceless." i wish that was the case but history has shown that most consumers are badly informed and/or stupid.
Its the old razors and blades trick, sell the printer dirt cheap to tempt customers into buying it (or better still to get it included as part of a package deal) but make consumers pay through the nose for the cartridges.
of course this doesn't work if people start buying copycat cartridges or refilling existing cartridges. As a result printer manufacturers nowadays do everything in thier power to stop people doing that.
flying cars have many problems some strictly techincial, some human factors and some political.
the key techical problem is how to make something that is as narrow as a regular car that is capable of flying, is safe and is not an insane gas guzzler. Removable or folding wings are a possibility (and i beleive flying cars like that do exist) but they mean you need a wide runway to take off just as with a regular light aircraft. They also mean an extra point of failure. Flying without wings is extremely gas guzling.
even if that is solved there is the issue that learning to fly takes much longer than learning to drive and the crowded airspace caused by mass use of flying cars would make things much harder to control. There would also be the political issue of setting up arrangements for people to launch and land thier flying cars near thier homes and workplaces
A game console costs between $200 - $600 and lasts you for five years or more. There are certainly more expensive hobbies then PC gaming, but then there are also much cheaper solution to play a game. depends on the genre you want. Beat-em-ups and driving games are well suited to console controllers and have a wide selection availible on consoles. shoot-em-up and RTS games are not well suited to console controllers and as a result many simply never come out on consoles or are crappy compared to the PC versions. Also some of us like mods which are pretty much non existant in the console space.
P.S. the last peice of computer hardware i bought for gaming reasons was a graphics card costing less than £25 (approx $12.5). What game is it that requires $600 worth of processor and graphics card?
playing games on a PC (which is an insanely expensive hobby) It is possible to get a quite reasonable machine that will play most PC games released for a few years acceptablly albiet not at the highest quality settings while paying less than £1000 Games rarely cost more than £50 each.
If you buy 10 games a year (which i'd say is more than enough if you check out reviews or demos first) and spend £1K every two years on a new PC thats a total of 1K a year. In reality you can get away with spending a lot less especially if you don't buy games the instant they come out.
£1000 a year is NOT an insanely expensive hobby. A single clubbing trip could eailly cost you £50, do that on a weekly basis and you are up to £2600 a year!
The US says they can sail through Canadian waters in the Arctic just because they can. which is really how things have always been. Countries are the top of the power heirachy so they can do anything that other countries don't stop them from doing.
afaict canada is far more dependent on the US than the US is on canda and they certainly have more military power so canada isn't likely to do anything about something like this.

What voltage were you using on VPP?
In Europe they have tiny 330 mL cans.
though at least here in the uk the 500 ml plastic bottles seem more common.
couldn't you just stock up at passover? or are the expiry dates too short for that?

replace the first intel in that comment with amd. I know intel have a quad core xeon.
