Yes I noticed that the other day. However, there is a transaction fee for each transaction (something like a nickle). If the vendor could batch your purchases every month or so it would save them money.
I always thought it would be cool if drink and food vendors would personalized your drink cup with personal information that is printed on the cup or sleave on demand.
It would work like this. You register and create an account with say Starbucks. You log in to a website and enter your CC to use to pay for your drinks. You can also upload pictures of love ones or select from default designs, you can enter the stock symbols you are interested and the news categories you follow.
Then when you are on the go you buy yourself that tall Americano, flash them your card or some id. When you drink comes out there is your cup is personalized with a picture of your main squeeze, your current stock quotes and bulletized news updates. Heck when on the road i would stop and grap a cup just to get a picture of my family and check on my stocks.
Also more efficient for the vendor as they do not have to give change or process a cc for buck and half.
Let this stand as prior art if some company tries to "patent" this some day.
However, a lifeform that engages in exploring, propogating and conquering (aka rape, pillage and plunder) would be effective at replicating their genes.
Would it not be likely that these traits would appear in alien evolutionary environments? Many examples exist of evolutionary convergergence traits such as wings (birds, bats, insects).
I suspect you have never really used Perl. Maybe had to maintain some newbies code or something like that, but that is extent of your experience with Perl.
Lets look at it this way. I propose that C provides more ways to code illegible than Perl. You can write horrible partitioned code, relying on precedence of operations, use lots of global data, recursively loading include files, using multi deep redirection when not necessary. Perl on the other hand has a some "features" that allow a coder to clarify their work, such as variable interpolation so that string concatentation looks cleaner
$str = "Time is $time in the $day day of the $month month.
vs
str = "Time is " + time + "in the " + day + "day of the " + month + " month".
Or the use of operators such as "unless", "or", "foreach", etc
Or the use of named parameters in function calls
Or the use of symbolic references.
Or use of the comments in reg expression.
I suspect the reg expression are the chief reason for your compliant on "ASCII explosion". Reg expression is a language of its own but knowledge of reg expression is pure power, it is compact expression where a single expression represents pages of code.
IMHO I love the intergral inclusion of reg expressions within the langauge framework. It is one Perl's strength. Without it would just be another "for,if,else,while,goto" language
Uhmmm... It's not free if you work and pay taxes. Lets see how much is that sales tax on all goods and services? 8% or is it 10%. And what is the average rate on income tax? Medical care is never free someone pays for it - its just a question of who you place the burden on.
Actually from my experience I would agree with the parent post. Perl is faster than blazes for string manipulations and file I/O functions which usually forms a significant part of most server side web applications.
I recently benchmarked an application that parsed large binary files, swapped bytes from big endian to little and sent the data out a socket to a remote application. I wrote the application in C and in Perl. Perl came within 5% of the performance of C, but the C program took me 3 times longer to write and debug.

A quote from this reference: Q: Perl had its place in the past, but now there's Java and Java will kill Perl.
R: Java and Perl are actually more complimentary languages then competitive. Its widely accepted that server side Java solutions such as JServ, JSP and JRUN, are far slower then mod_perl solutions (see next myth). Even so, Java is often used as the front end for server side Perl applications. Unlike Perl, with Java you can create advanced client side applications. Combined with the strength of server side Perl these client side Java applications can be made very powerful.
In reference to GUI's I just started playing with Perl/TK and was able to put together a short operator interface to view and filter a log file output. The application runs equally well in Linux, Windows and Solaris. I have not played with it enough to determine the weakness of the combination but first appearances are impressive.
All open source (teams|foundations|etc) should have a means with which to accept payment and set a standardized "corporate quality distribution fee" for those who must pay to feel good about the transaction.
I have run into this snobbish attitude also in my consulting work. I have been told on occasions "sorry son, we only use corporate quality software here"....ha ha lol... What ever the heck that means! I always try to contain my mirth.
If when proposing a particular solution I could quickly add that a site licencing fee is only $850 most corporate customers would not even flinch and would somehow feel more comfortable that they are not using some "freeware" or "shareware" product to run their business.
Plus, interpretted languages are pretty silly. They just have to be recompiled again and again and again. The dynamic linking is kind of cute, but that's not an excuse to repeat it a million times.
Actually compiled languages are kinda silly when you could hand craft your code in assembler and not have to waste all those cpu cycles compiling and linking over and over as you develop:)
Apache has a nice page on common myths surrounding Perl web applications here
Performance in a particular language depends on the task and more importantly the skill of the programmer. Also, usually the most import factor is developer time.
Designing and writing programs in Perl, Python, Rexx, or Tcl takes half as much time as writing in C, C++, or Java and the resulting program is only half as long.
No differences in program reliability between the lanuage groups.
Typical memory consumption is about twice that of C/C++ but Java programs was another factor level higher.
O.K. lets compare syntax. List what you consider to be hideous Perl code and contrast it to comparable code in your language of choice. Chances are the syntax is not what is making the code unmaintainable but bad design or your unfamiliarity with Perl or programming in general.
Perl combined with a good template parser and you have the best tool for developing web apps. Perl is fast, stable, powerful and ubiquitous.
The primary mode of PHP development is to mix code within your html. This works for small or single purpose applications but sucks if you want to develop a server app that uses several different sets of templates customized for different users.
So you first off exclude haploid stage as a determination of human status - good most people will agree. But why does that exclusion lead to you to the the "diploid or else" conclusion?
I think there are a lot more reasonable thresholds for making a legal determination for "human" status - like brain activity, viability, sensation of pain, etc.
Check it out for yourself. Cells. Caution not for the weak of heart.
It is too bad that the fundies have seized hold of this issue and bundled it with their twisted worldview.
The real question is when do you call your "bundle of cells" a human being. I believe that long before a baby is born they should be given the same basic human rights you and i enjoy. Just because a fetus cannot speak for themselves does not mean that they are inanimate objects that can be flushed down the toilet without regard.
I wonder how many whining techies here that are loudly proclaiming "Hire American!" also dribble disdain about MS anti-competive practices and attempts to manipulate the market?
A global and free market place is the way of the future. You will need to learn how be competive on a global scale and not try to place artifical barriers to "protect your market".
I think you would have to narrowly define "public". What about folks who write software to launch and deliver an ICMB - since destruction and killing is sort of the idea.
The Axis 2400 video server also uses embedded Linux, not sure which flavor.
We have an older 2400 and when I recently upgraded the firmware they had switch from whatever they were using to Linux. I was impressed. In addition to adding a number of new features, including a doubling of the frame rate, I got a command line on the server!
The server is used to post images on a weather site here
Ok hows this: Have you splurged on yourself lately. Maybe bought a new pair of shoes when the old pair would have got you around for a while longer. Or maybe eaten out when you could have eaten at home. You could have sent that money overseas to help buy that medicine. Did you put your own selfish greed and avarice over people - causing deaths and pain?
It is a much more complex issue then you make it out to be and easy to center the problem on evil and heartless corporations.
Please demonstrate or give specific examples how Perl's "unelegant" after market OO implementation results in program design that is more difficult to maintain. Just interested.
I sort like the ability not having to use a OO approach for some programming problems.
MS has the luxury of being able to dedicated significant resources in new market areas that would cost other companies dearly if they failed.
For example, they missed the emergence of the internet but where capable of recovering by buying their way in.
MS has a history of failed initatives but have been very successful at buying the best-of-breed in a specific market area and quickly dominating that area. They should be forced to compete with the best companies and not allowed to buy them and thereby reducing the competiveness of the market.
I hope they have added a metadata section where data like author, date, etc could be attached internally to the image.
I always thought it would be cool if your digital camera could include the settings (fstop, exposure time, ISO, etc, compression ratio) along with data, time and author directly in the image file.
if @foo[n] was a scalar then what would you do with @foo[1..5] which is a slice and not a scalar but multi-valued and hence the "@"

Dear ACLMAO
Correct me if I am wrong ( I am not that long in the tooth) but I think the use of "$" to signify a variable came from shell script, which predates BASIC. Also, I do not believe BASIC used "%" or even had a hash datatype.

Agreed. I like to think of the prefix char as a sort of Hungarian notation short hand
instead of pchFoo you have $foo
once the $%@ are part of your mental character set then reading Perl is natural and simplified.
Also helps to efficiently indentify naked strings from variables. This convention makes possible the ability to perform variable interpolation within strings. This feature greatly enhances readablity.
For example
$foo = "Good morning $name it is $time $zone";
instead of something like:
foo = "Good morning " + name + " it is " + time + " " + zone;

Same here, I been feeling the guilt.
From now on when I bid a project and the project uses Perl I will include a $50.00 surcharge to add to the fund.
I was not questioning the cost of medical care or even commenting on who has the better system. I was reacting to the concept that it is "free" !
I work, I pay taxes, and then there are those who don't - they spend their days manipulating the system and live off the hard work of others.
I have sensed that more and more Canadians are developing a sense of entitlement. That is the government owes me (fill in the blank). Just my opinion.
"I walk in with an ID card and get free care"
Uhmmm... It's not free if you work and pay taxes. Lets see how much is that sales tax on all goods and services? 8% or is it 10%. And what is the average rate on income tax? Medical care is never free someone pays for it - its just a question of who you place the burden on.
