Back in my day, we hand assembled. Actually I did hand-assemble the first month or two. Most of my programs were fairly small. I picked up Buddy / Pal assembler and it changed things.
Hand assembling gives you a much better understanding of how the code actually works and allows you to understand:
Naaah. Check my posts - I'm not on here constantly.

Actually, I'm usually the ones that's showing / installing new applications for her ( I like her I-Book - I want one. Must remember it's hers. It's hers.. not mine... ).
I install new apps; she usually finds strange web pages that we both enjoy. It's an even trade.
I've always considered the 6502, more or less, a RISC processor due to it's uh, "simpleness".
It has 3 register, 8-bit address lines, 1 accumalator and two index registers. That was pretty much it along with 52(I think) opcodes and variants in terms of addressing modes.
The chip was neat in that it was simple enough for someone programming it to be cognizant of everything going on inside the processor: Ok, at this stage the accumalator is __,.X is __,.Y is __ and the carry flag is set and the Z flag is off were my normal thoughts while writing assembly.
I can't speak for any of the other 6502 computers but the way that it was used on the C-64 was an engineer's wet dream. It was coupled with other chips that were simple in their operation but complex in their innards. There was no filtering of bad input data - if you fed it crap, the chip was free to interpret it however it wanted.
This ability to send "crap" data was pretty neat because once you got the timing down right you could do pretty miraculous things - that weren't even listed as features for those chips.
Bonus question: How can you disable the NMI interrupt on the 6502? (Yes, there is a way).
My wife has a non-technical background and is actually more of an anti-MS zealot than I am. Her reasons? Things tend not to work in Windows. Under Linux or OS-X things just work.
She doesn't need to install applications contantly.( Hopefully that'll be 1 more reason to keep me around). She doesn't browse networks etc - she primarily just uses it for email, web access and ocassionally typing a paper or playing dvd's or mp3 music. She's even learned how, on her own, to rip mp3's and organize her files logically.
Shifting back on topic now, she much prefers the style and appearance over KDE/GNOME, or OS-X calling windows "clunky". The others are more "artsy" ( her words ) and more pleasing to her.
you know - the RFID tag that can be detected and is very small and tiny - put it near a RF emitter and it sends out an ID code.
Rig that up to your computer room entrance. Then when she walks near it - it will automatically lock the door or unlock it depending on the mode that you've got it in: PORN or NO-PORN.
>> I don't mean to sound like a downer, if anyone actually finds it funny, but I feel compelled to speak out and say that, well, I don't find this particular bit to be amusing, at all.
Ah - I see - Can you post a link to your website that previously got slashdotted?:-)
I believe the C-64 noise on voice 3 was from a R/C circuit imbedded in the SID (sound) chip. It was good for low-level randomness ( 8 bit ) but not for more than that.
The random number generator in BASIC was fairly crude - I believe mantissa/exponent based but am too lazy right not and not enough space in the margins to go look it up and post it.
The most commen way to get sorta ok random numbers was to use the second timer as a basis to seed the random number generator.
Either that or :
while( peek(198) == 0 )
i = i + 1 ( it might be peek(198) == 64... )
Oh, so this is what the press release by Pioneer should say?
Users of the superdrive engineered by Pioneer Electronics may suffer ill effects from use of the drive with new 2x and 4x recordable medium. Use of this product has been known to induce spontaneus combustion, decaptitation, explosions and is rumoured to be cancerous. Those users who are able to still write ( bloody stump or not ) may address Pioneer Electronics for a partial refund - please continue to use the product in the meantime as if you die - it'll mean less payments for us. This product has been show to burn labratory rat animals in tests on 2x and 4x recordable mediums.
Hold on - If a bill collector calls demanding payments then he is legally protected by law so as to make any claims/statements he wants as long as they do not involve physical harm.
What's to prevent this guy from doing the same thing? I see no differance here.
If you RTFA ( Read the Freakin' Article ) you'll see it's not a photoshop touch-up etc. I get the feeling that it's two groups with similair concepts that drew something similair.
One may have been based off the other but name me a superhero that isn't based off of superman ( not really - you know what I mean ).
Use the language - don't go the long road by using functions such as ngettext and don't write code to support to implement a feature that the language already represents. If however, use of the language feature would cause confusion or code to be easily misread, then go ahead and implement your own ( eg: use if's instead of nested ?'s ).

Why not ask MS to sign the linux kernal on the X-Box?
I'm not sure what it takes to ask for a signing but it would provide interesting fodder for the Dept of [in]Justice.
It'd be the perfect Catch-22 to put Micro$oft in. If on the 1 hand they deny it then it looks bad for the predatory practices they've been doing. If they allow it, then it'd be good all around but not so good for M$ as they'd have to bump up their prices to a self-sustaining level and wouldn't be able to leverage their cash cow.

will now be pulled from the libraries. Geesh. And that was one of my favorite books too...
My question then becomes - do we need Contrail "spoilers" on the wings of aircraft ( probably at a reduced milage/kph rate ) and if so, what's the best design or would they even disperse enough to have contrails disappear?
All of the "wars" that America has handled for the past little bit has been through a build-up phase on orders of months or so. If there is a super-quick way to move men/materials/totally cool *hit in then the enemy will be in a relaxed posture.
Actually what makes the parent post intriguing is this.
Currently the US has a set of Satillites that can form a communications relay and then beam messages to the ground.
Suppose we have some black birds ( Satillites ) that operate solely on Nuclear Power with passive ( eg visual / thermal etc ) pickup of information / images. Now, let's broadcast the data to the communications relay and send it down encrypted.
Since the birds doing the oberservation are "dark" - there only encryptions being laterally to earth's orbit their flight paths wouldn't be known.
This has been known for some time. The claim, when I heard it, was that particulate matter in the air from exhaust etc gave the water vapor something to coallese onto and hence form water droplets. I think particulate matter is more reasonable to expect than temputure variations ( even tho these do exist ).
Why is Nasa re-inventing what is already known? This was out about 5 years ago ( or longer - memory rentention tends to blur ).
sys 64738 - Man, I've been looking for that for the past 2 weeks trying to rack my brains as to what it was... Geesh. And of all places to find it...
NP=P
when,
N=1
P=0
P=257 where N between 0 and 255 and = assignment is only allowable for 8 bits and dropping of high bits is done for overflow.
a round of been after loads of symbolic algebra, computational match classes.
If you want to crash it try messing around with location 1 which is where memory banks / how the C-64 is segmented memorywise can be swithced in and out. Flip out the ROM's while IRQ's/NMI's are enabled and kablooey.
BTW, It is possible to disable NMI's on the 6502 line... Just enable and trigger an NMI and then never RTI from it.

Where to find an assembler?
Back in my day, we hand assembled. Actually I did hand-assemble the first month or two. Most of my programs were fairly small. I picked up Buddy / Pal assembler and it changed things.
Hand assembling gives you a much better understanding of how the code actually works and allows you to understand:
LDA #$01
BIT 169*256+0
which would allow the following:
LDA #$01
LDA #$00
depending on where you jumped.

Actually the reason we waited so long before attacking Iraq I really believe was because Iraq could not maintain distance supply lines for too long.
Lack of supplies means lack of moral.
Lack of moral means pigeon shooting when it comes time.
