Unfortunatly, it's not always a GOOD reason. Many of these companies who create filters seem to have an agenda. An agenda mandated by law is not good.
While it may be possible to get information on womens rights, safe sex & other things inappropriately filters at the moment on paper, I for one do not want to set any precedent that these are acceptable things for a library to filter out.
an infinite number of years before you're allowed to smoke a certain type of plant.
Don't forget, you're not allowed to go on vacation to a certain caribean country, or smoke cigars made in that country, just because the US's choice of dictator was overthrown by his people.
The only solution I've seen which has any degree of success is to put the internet terminals in a position where they can be seen by the librarians and/or other adults. No kid wants to be SEEN viewing pr0n.
This has the additional advantage that it also discourages theft & vandalism, a problem which is not yet solved by software.
I don't have any URL's, but I recall that in 1984, Primos machines suffered an outage when the backup program attempted to create a tape to expire on 29FEB85.
I'm sure there are many instances before that, but i'm not familiar with them. I'd say that date's have always been a problem in programs, simply because they're so complex, and easy to get wrong.
The modern gregorian calendar was introduced by Pope Gregory XIII in 1582. However, it was only adopted by roman catholic countries in 1582, other countries, including Britain and Russia remained on the Julian calendar.
1600 was a leap year in both the gregorian calendar and in the julian calendar, and 1700 was a leap year in only the julian calendar.
Britain (And it's colonies, including America) adopted the Greogrian calendar in 1752, but other countries switched at other times, eg Egypt in 1875, Russia in 1918 and more recently Turkey in 1927.
So depending on where you are, the last '00 leap year could have been in 1600,1700,1800 or 1900.
It's certianly not an 'accepted convention' that example.com == www.example.com.
It's perfectly acceptable for example.com & www.example.com to point to two totally different websites, for example here & here. It's also very common for there to be no hostname associated with a domainname, simply because there is no 'obvious' host to associate with the domain. While the http protocol is very pervasive, there may well be a better candidate in the default telnet server or some other protocol.
Don't be lazy, a URL contains a protocol, a full hostname and a file reference. Enter all of them at all times.
I disagree. I think the realistic chances being killed by a nuclear weapon is much higher now than in the 50's.
In the 50's, nuclear weapons were only possessed by a small number of nations who were generally well accustomed to diplomatic means, had no major entrenched hostility to each other, and had just fought a long shattering conventional war.
The weapons were controlled by the military, who put many procedures & safeguards in place to prevent the accidental or unauthorized use of the weapons.
The only way that nuclear weapons would be used would be for a conventional war to go hot, and since the second world war, none of the nuclear powers have directly fought each other.
Nowadays, almost any nation could get a nuclear weapon if they decided to expend the effort. This includes many countries with leaders who obtained control by miltary means, have disputes with their neighbours over control of territory or resources, and sometimes have religious or other disputes with their neighbours going back thousands of years, and modern disputes with the USA and the United nations.
A country which has already sent suicide bombers against US targets, or is fighting a bitter border war with it's neighbour is going to be more likely to use an atomic weapon than any of the nuclear powers was in the 50s.
You can get drives like that, they're used in the record to hard drive boxes. One is used for reading, and one for writing, so you can do both at the same time.
Of course, you should still worry about the noise even if it's not audible. Ultrasonic noise can do damage to our ears just as easily as normal noise, even if there aren't any harmonics in our range of hearing.
Especially since the books are made obsolete whenever new versions of the software come out.
This is exactly why computer books are expensive. If you make "Milking cows for dummies", you've got a high upfront cost (writing the book), but you can make that back over a long period of time, as cows in 1990 are the same as cows in 2000 and 2010.
On the other hand, if you make "Cowsoft Milker 2.0 for dummies", then you have the same upfront cost, but you can only sell the book until Milker 2.1 comes out. Sometimes you can revise the book, but this is an additional cost.
Doesn't this imply a bad design for COM, rather than anything about C++?
I've written Unix daemons in C, Pascal, Modula2, Perl and even Fortran.
Generally the Unix model of system calls works well in most languages, though some system calls are awkward in some lanaguages (select for example is hard in languages which can't do bit twiddling). I think that expecting people to program in their choice of languages is a good thing, and that os designers & implementers should make it as painless as possible.
If you've got a huge investment in SNA/mainframe, and you need to develop a new app, are you going to spend $x to develop the app, or $x + $y to develop the app plus a new network?
We could use every app we've got using TN3270 over TCP/IP instead of a 3270 emulator over SNA. However removing the SNA equipment and replacing it with TCP equipment costs money, for no benefit to the client.
Applications which require TCP/IP do of course use the TCP equipment & network, but here is a small fraction of the SNA network at the moment, and will be for at least the next several years.
There is a huge difference between wanted to wanting to "release to coincide" and "preventing you from using your DVD on the 'wrong' player".
Many items have seperate releases in NA & in Europe (& probably other markets, but I have no expericence there). Books, CDs and movies are often avilable first in one or the other area. There are rational reasons for this, they are different markets and sometimes the promoter cannot afford to promote in both markets at the same time, and actors, auothros etc obviously cannot be in two places at once. No-one objects to this, it's a fact of life.
I can obviously read a book bought from anywhere, and I can buy a VCR tape from wherever I want, and play it. The only restriction is that different countries use different formats, and that's historical, with many modern VCRs handle oth NTSC & PAL/SECAM. I can also handle the formats of books used in Spain and France (With a little difficulty, but that's my fault nothing to do with the technology).
I emigrated a few years ago, and took lots of CD's with me. I still listen to those CD's, and I've also bought several imported CD's over the years, first those brought over from region 1, then those brought over from Europe. I have books bought from all over the world, and I could have taken my VCR tapes with me if I decided to buy a multiformat VCR.
Can anyone give a rational reason why DVD should be any different to these other media?
Now that IBM big iron talks TCP/IP, HTTP, ODBC, JDBC, XML and so on, and even runs Linux in a VM, why would anyone bother with a SNA-based client application? And without the special application support, why bother with the 'deviant' OS? (to quote an old dilbert strip)
Because the people who run mainframes usually have 30 year old applications that they rely on a daily basis, and which are based upon SNA/3270?
The company I work for is like that, and while it could theoretically replace it's SNA network with TCP, it needs a business reason for doing so, and so far there isn't one.
The 15th to 17th centuaries were quite remarkable times, there were people out discovering things and inventing things at a rate which we've never seen since (The overall rate is higher, but they're discovered/invented by many more people, meaning that each person discoveres or invents much less). There are several people who had skills in many different areas, and are still remembered today, Newton, Leonardo, Napier, Pascal, Wern, Tycho Brahe, Kelper and many others have resumes which would seem to be unbelivably broad if they existed today.
Nowadays, everyone is a specialist. An artist could never be a respectable mathetician. These gentlemen were metheticians, astromoners, chemists, artists, architechs, physicists, writers and other professions too. Not just one profession each, but usually 2 or 3 or more all at the same time.

In 1988 a bunch of sun's stopped working, and people who created accounts with ADM (whatever that is) found they couldn't log in. A bunch of BBS's Crashed.

Newbies? I get confused when I go to a site and can't clearly see where the links are.
It's perfectly acceptable for example.com & www.example.com to point to two totally different websites, for example here & here. It's also very common for there to be no hostname associated with a domainname, simply because there is no 'obvious' host to associate with the domain.

Because of PHB who don't understand the technology or the content who are put in charge of building websites?

burger flipping also contributes to RSI.
You have a @ on the lhs, and a $ on the right hand side. Unless you're sure that's what you want to do, it's probably a mistake.

The more you tighten your grip, Tarkin, the more star systems will slip through your fingers.
No, but by the 19th C it was rare. In those times, it was common.
Not arguing, expanding.

No, you use square brackets instead @a=([1,2,3],[4,5,6]); Comes to the same thing though, just with a difference in the syntax.
It's easier to clean up if a process core dumps.
