Exploring Some Lesser-Known Scripting Languages

kleinesRaedchen Re:Who supports it (60 comments)

Python had similar semantics but much better syntax. It practically documents itself if you do it right.

True for almost any programming language including Perl.

Perl's Glory Days Are Behind It, But It Isn't Going Anywhere

kleinesRaedchen Re:Those are called sigils. (379 comments)

you got me on this one ... I wanted to reply that the Perl interpreter (with warnings enabled) would happily warn about it. But then I performed a short test: "this_is_a_perl_3012_keyword" doesn't trigger a warning, neither do "thisisaperl3012keyword" nor "this_is_a_perl_keyword" whereas "thisisaperlkeyword" does. Seems to be some weird promise: Perl keywords will never contain underscores or digits. Another distinction mechanism, hooray!

DNA Confirms Parking Lot Remains Belong To King Richard III

kleinesRaedchen How strong is DNA evidence after 18 generations? (212 comments)

There are at least 18 generations between the remains found and the existing potential relative. So they probably only share a 2^(-18)th of DNA. That's roughly 4 in a million parts. Admittedly, DNA isn't inherited randomly at the level of nuclear bases. Instead inheritance works on the level of genes (in my understanding). But those are only around 25,000. So, how many matching genes where found here? How much is this above random level?

Perl's Glory Days Are Behind It, But It Isn't Going Anywhere

kleinesRaedchen Those are called sigils. (379 comments)

By separating variables to a namespace new keywords could be introduced anytime. Just try this in a language without sigils. So, it's a cool feature guaranteeing compatibility of nowadays Perl scripts with Perl interpreters in 3012.

What's In Steve Ballmer's Inbox?

kleinesRaedchen Re:Reminds me of back in the day (93 comments)

The policy in our university IT department was "login equals lastname" unless that one was already taken. (In that case, one or more letters of the firstname were prefixed.) Check and generation of accounts were performed by a home-brewn script. That script, however, did not check against system accounts. One day, a newly registered student, Miss Root, got a very special account ...

Army's Huge SAP Project 'At High Risk'

kleinesRaedchen C and ABAP (166 comments)

The SAP R/3 kernel is written in C. The application layer is written in ABAP and can be extended in ABAP or Java. So, the the claim with COBOL is BS.

US Grants Home Schooling German Family Political Asylum

kleinesRaedchen Home-medicating a human right, too? (1324 comments)

From time to time we hear news about parents who do not want to get their children medically treated, even if they suffer of serious diseases. This is a human right, too, isn't it? The doctors in the hospital are all quacks, aren't they? I find the whole concept of parents determining childrens faith and beliefs questionable. Transporting values by giving a good example, ok. But forcing membership in a religion by dubbing the little lads before they even know what's going on? That's perverse.

Best Tool For Remembering Passwords?

kleinesRaedchen Use hashing algorithms (1007 comments)

I created a small shell tool for myself. I'm entering some characters and the tool performs a incremental search in a file containing login identifiers (e.g. kleinesRaedchen@slashdot.org). Then it asks for a master password. At its core the tool creates a login specific password like this:

PASSWD=`echo "${login}${masterpasswd}" | openssl dgst -ripemd160 -binary | openssl dgst -sha1 -binary | openssl base64 | head --bytes 8`

The password is stored in the KDE klipper for 20 seconds afterwards.
