He seems to have a tendency to represent the worst possible uses of various things as typical usage, and ignore a number of useful things.
For example, he claims that the security uses of stored procedures have been replaced by role based access control. That's incorrect. If you want to audit changes to a table using RBAC then the user not only needs access to the audit table but must always update it themselves. A user could easily cover up changes by simply omitting the audit row, or adding false data. The use of triggers and stored procedures can enforce the audit, and protect it from malicious update.
His claim that triggers are a bad idea because a novice DBA once disabled them on a production database, not realising that they existed, is just silly. The fix is to ensure that people get a clue before they get superuser access! Triggers are a standard part of every big modern database, and a standard part of any training program.
I could go on, but I don't really fancy debunking every silly thing people write about databases...
No, it worked without the handset, and just the components. In effect, the whole lot, power supply, both microphones, and both speakers were wired in series. The old microphones weren't amplified moving-coil types. They directly varied the current through the system, so an input to either mic was heard in both speakers. Isolating the directions would have required two pairs, rather than the one that was actually used.
It's pretty much a standing joke in the EU, that there's a hypothetical department that comes up with stupid rules just so that everyone can laugh at the British for trying to implement them when every other country knows not to bother...
People are perfectly capable of evaluating whether something is obvious or not after the fact. They don't mystically lose their intelligence simply because they have more facts at their disposal.
The facts beg to differ. Research in to negligence cases shows that people are far more likely to rate something as obvious when they've seen the outcome.
I can't remember who defined genius as "The ability to see the obvious things that others miss.", but it's sometimes useful to remember.

It depends on what you're doing. If you're doing support for companies with multiple sites, and users who hot-desk between them them an M-M relationship is sensible.
I would suggest that holding material of questionable moral content is an important function, even if only to further the historical record so that future scholars can see where we drew the line. Leaving an accurate record of our times does future generations more good than than trying to erase those parts of our culture that some find objectionable.
Tandem got bought by Compaq and became "Compaq Himalaya", which was then bough by HP, and is now "HP NonStop". But IBM do the lockstep processors too, as do a couple of other companies.
The sensationalistic version of the debate is "Does Autism actually exist?", which is kept alive by the fact that the simplistic answer is quite likely to be "no" which runs counter to most people's observation.
But that's the problem with simplifying the dabate to that level -- the answer seems entirely wrong. The question should be something like "Is there a single epidemiology behind the colletion of symptoms known generically as Autism? Or is Autism a too-generalised term used to cover a number of unrelated problems that cannot be treated, or even considered together? Might Autism in fact be just the tail of several kinds of natural variation and thus not something that can properly be labeled a disorder?"
Unfortunately if you put the radiators under the windows, you just end up heating the air between the window and curtain and wasting far more energy than you would by putting them nearer the core of the house. I've lived in places both ways round and found having the radiators near the core was both warmer, and more energy efficient.
The daftest choice of radiator position however was one laboratory at university, where all the radiators were under the fume cupboards.
It isn't content switching, it's IDS stuff. This is what the Wind River(?) stuff does. (An Isreali (I think) company that Cisco bought recently) The short version is that DDOS tools don't follow the redirects, but real browsers do. Thus the first request from a new IP address gets the bounce treatment, and if it's followed, then you're flagged as good, otherwise you're flagged as a bot. It's slightly more complex in that it isn't actually the web server returning the request, but the box that intercepts the request.
The long answer is complicated, but the short answer is that the UK did originally act in a similar (military) manner to the US. But on the other hand, until recently, modern terrorism in the UK grew out of military action as the original military organisations came to a political settlement and a more radical group splintered and carried on. This was repeated several times until it bacame basically gang warfare with religious excuses and political aspirations on both sides with the government trying to get them both to stop.
Because telling a potential enemy exactly what you're doing is generally unwise. Because doing so would screw up a lot of counter-intel strategy. Because the source to a hypothetical "void fix_gimbal_lock(radar_controller_t *cont)" would tell an enemy the one approach vector that your radar systems can't track...
Why can't a chair just spontaneously shift position?
It can, it's just very, very unlikely. The probability of a single particle moving far enough that we'd be able to notice is extremely tiny. The probability of the chair moving is thus that probability divided by the number or particles in the system (waves hands around things like different masses etc.) and may reasonably be expressed as; the square root of bugger all.
Secondly, the energy required is substantially less than that required for combustion, which makes it more likely that you'd notice the chair being on fire.
But the probability of a chair spontaneously moving is calculable.
They are already back, just in the form of CDs and DVDs. A media which encodes data as physical holes in it... (or tricks the reader into thinking there are holes).
Novell used to do freebies, 5 user, non commercial, stuff like that. You probably didn't see them because it's not like they were advertised in any useful fashion. I only knew about them because I worked for a Novell reseller -- it's not like they'd be of any interest to the average home user.
The other big commercial OS available free would have to be Solaris, and that's free for commercial use as well, for however many processors it is today.
I know what you mean!!!
I had the worst time putting AIX 5.1 on these old RS/6000s we had laying around. Sure, they were about 4 years old, but that's ok, right? It's still a RS/6000!
On the other hand, Solaris 9 installs just fine on 4 year old UltraSPARCs, indeed it works just fine on my 10 year old SS10. It doesn't support the 3/80 I used to have, but when you get to that sort of museum piece hardware it's usually more fun to run either the original OS, or one you've written yourself.
The idea of a one way trip to mars was suggested at NASA in the '60s, for the same reasons. My correspondant reports that there was no shortage of volunteers from the people on the Apollo missions. It is possible that people underestimate quite how dangerous the moon missions were with the seperation of more than 30 years. The history of space exploration was built by whackos like that.
I think you probably mean "getting LaCie external drives to work on Windows is an exercise in frustration." I've never had a problem with them under x86 Linux. Plug it in, it works. Same with my Mac.

The UK abandoned the use of pounds-shillings-pence (abbreviated to LSD -- think Latin) about 35 years ago.

But yet for all the arguments above, the NHS still delivers a more efficient and cost-effective service than the private sector...
So, much the same way as it works in most western countries?

From the Solaris 8 code, it may or may not still be there:
