The problem with the 6502 was that if you were writing code for someone else's environment then your use of Page 0 (which many of the index-based instructions used intensively) was restricted because the OS often took up most of that space.

If you were writing code that was totally stand-alone (ie: no bios or OS to worry about) then the 6502 environment was *very* nice and could perform incredibly well. However, if you were writing code that sat atop a BIOS/OS layer then the Z80 was just so much simpler and less frustrating to code for.

Speed-wise, the Ohio Superboard (6502) would roundly trounce a TRS80 Model 1 in single-precision floating point math run through the relevant BASIC interpeters and ultimately and tightly coded 6502 code would also trounce the same written for the Z80 -- unless Page0 was already used up on the 6502 system.

In the old days, before computers went solid state, smoking on startup was often put down to worn valve-guides.

Damn... I think Americans call them "tubes" -- in which case the joke doesn't work :-(

Who the hell is going to sit down and scan a few million lines of source code with Microsoft looking over your shoulder and hope to spot a backdoor or two in the process?

Even then, how can you be sure that the source code they show you is the stuff you're actually running?

What a PR stunt this is!

Please cite the FAA regulations that state this.

I think you'll only find an *advisory* which has no legal standing.

Forget about aerial video and photography with these "drones" -- the most fun you can have with one of these multi-rotor craft is this:

FPV racing

These are tiny multirotor craft fitted with FPV (first person view) video gear and flown around a course (which can be as simple as a few trees in a field).

Stunningly good fun and a real adrenaline buzz -- without all the privacy and safety issues that "droners" create with their DJI Phantoms and other consumer-grade multirotors.

Just Google/Youtube for "mini H quad" and you'll find much more

Actually, they are *not* regulated -- and that's the big problem right now.

From the FAA's perspective, there are no regulations pertaining to RC model aircraft -- only guidlines.

This is why the courts overturned a $10,000 fine levied against Raphael Pirker by the FAA -- because there are no regulations to back up that penalty.

The FAA are scrambling to come up with some regulations but, until then, they are hoist by their own petard (or lack of work in this area).

It simply means that there is not enough scientific data to support any hypothesis conclusively, not that they have no clue whatsoever. Do you have any data to back up your hypothesis or is it just "common sense"?

How dare they include the Me163 Komet in a list of "worst planes" -- it was a groundbreaking craft (in more ways than one -- get the pun?) which highlighted the innovation (and desperation) of the Germans near the end of WW2.

Yes, the choice of fuel components made it horrendously dangerous and the limited flight-times did reduce its utility but it was undoubtedly *the* fasted aircraft of WW2.

Alarms simply tell you you've been robbed.

A far more effective strategy is to ensure that anyone entering your house uninvited will find it impossible to stay long enough to steal your stuff.

To do this, you want lots of *internal* sirens that run at 120dB+.

If the intruders ears start bleeding as soon as they enter the building, they will retreat at a very hasty pace.

That's how my alarms are configured. They ring me over the cellular network and generate an internal sould level that is intollerably loud (as I have discovered on the two occasions I forgot to disarm the system myself) :-)

If he's going to get your iPad he might as well take some life-long hearing damage with him :-)

Fortunately I still have some of those old Kodak Gold CDRs that were guaranteed to last 100 years!

How do I claim on that guarantee now I wonder? :-(

Don't believe it... just understand that in NZ, the authorities are much better at hiding it.

Corruption, hypocrisy and graft remains rife in this country it's just that we're a nation of 4.4 million sheeple who really don't give a damn.

The great Kiwi saying "she'll be right" is killing this nation because nobody is prepared to stand up and speak out when they see people in power doing bad things and abusing that power.

"a very unique milestone in space exploration"

WTF?

"unique" is not a relative adjective. There are no degrees of "unique". Something is either unique or it's not.

Aaargh!

That's why there are no such words as uniquer or uniquest

And my Cassio FX-115, going strong since the very early 1980s and it has *never* needed a replacement battery (perhaps because it's totally solar powered).

Why is it that the ads in mags like Byte were a key part of the reason I bought the magazine -- but banners and online ads have become little more than annoyance and irritation?

The old print-media ads were informative and didn't slow down my reading in anyway so I guess they were excellent "secondary" content.

There's no way I'll patronize any site that uses full-page interstitial advertising -- yet the full-page ads in Byte and other printed mags were things I often read from start to finish.

Is it just me or have others had the same experience?

Modern 2.4GHz RC gear requires a significant level of tech-expertise to "hijack" in the manner suggested.

Occam's Razor has the answer...

Simple mechanical, electrical or operator failure -- nothing more, nothing less.

Too many would-be "drone" operators have scant understanding of the need for a maintenance schedule and proper planning before deploying even the smallest and most lightweight of craft.

The problem is that far to many people buy these things and then treat them as if they'll just keep working forever -- simply charge the battery and fly!

Unfortunately, props fatigue, motor bearings wear, ESCs can overheat and flight controllers can fail.

There's a hell of a lot more to safely deploying one of these craft than flipping a few switches and wiggling some sticks.

I'm not a commercial operator -- I fly for fun but even *I* am very much aware of the importance of good housekeeping and planning when it comes to using these things safely.
