Perl regexps not matching string with leading zeros / incorrectly escaped numerals with leading zeros on command line in Perl
by undeinpirat in Programming Languages

I have updated this question, as in the original question the issue I was chasing turned out to be an alltogether different bug (not interesting in this context). But the second order mistake I did in testing is something others may run into and produced an answer with a very interesting insight, so I'll leave this here as a question.


I was trying to track down an issue with regular


How to Fix an ESN With All Zeros
by Demo24 in Electronics
A cellphone's electronic serial number (ESN) is what tells the cellphone carrier, like Verizon and Sprint, who the phone belongs to, what carriers it has been activated on and if it is stolen. Sometimes when a cellphone is reset by the user, the ESN resets to show all zeros. The phone will not operate correctly if this is the case, but there is a quick programming fix for a reset ESN.Difficulty:Ea

How to Customize Dub Zeros
by Justin Bowers in Hobbies, Games & Toys
The Michael Jordan Dub Zeros are popular shoes originally made in 2005. Since the Dub Zeros' release, offshoots of the shoe began to appear, remaking the original white, red and black show to encompass more colors and styles. In addition, the Dub Zeros have become a popular shoe for designers to customize because of its style and uniformed color scheme. Customizing a shoe should be done with cauti

How to Find Zeros on a TI-89
by clifton anderson in Hobbies, Games & Toys
The zeros of a polynomial equation are the values of x that make the polynomial equal to zero. These values are referred to as roots. Depending on the complexity of the polynomial, determining roots by hand can be time consuming and make you prone to err. The TI-89 line of graphing calculators can solve many types of these equations, including trigonometric, rational and high-degree polynomials. K

5656 should be 565600


How is this possible using a Ant build script?

Right shift with zeros at the beginning
by nasy in Programming Languages

I'm trying to do a kind of left shift that would add zeros at the beginning instead of ones. For example, if I left shift 0xff, I get this:


0xff << 3 = 11111000

However, if I right shift it, I get this:


0xff >> 3 = 11111111

Is there any operation I could use to get the equivalent of a left shift? i.
