Bluetooth hardware recomendations

by Karl Hiramoto

I need a blue tooth interface for my PC, and wondering if anyone has any brands, or hardware chip sets to recommend. I will probably buy a USB or PCMCIA interface. Buying something USB though would allow me to use it in both my desktop and laptop, where only my laptop has PCMCIA. Bluetooth devices i want to hook too, claims it is something like rs-232 serial output over bluetooth, but i gota figure that out. After that i may try with a digicam or mobile phone. -- --- Karl Hiramoto <karl(a)hiramoto.org> http://karl.hiramoto.org/ Yahoo_IM = karl_hiramoto GTalk=karl.hiramoto(a)gmail.com ------

Re: [Wlug] Perl puzzle. Thanks for ascii man page

Ok. > The obvious s/, "/"/g doesn't work, nor does escaping the > double-quotes, as in s/, \"/\"/g There's no reason to escape the double-quote, it has no special meaning in perl RE (same with the comma, the space, etc). The first version should work, assuming you're doing the substitution on $_. ie: $ perl -e '$_=q/Foo, "Bar", "Baz"/; s/, "/"/g; print "$_\n"' Foo"Bar""Baz" If it's not something simple like operating on the wrong variable or $_ not containing the data you expect it to, a possible more obscure issue that I've run into problems with is related to a bug in perl (typically 5.8.0) where the double-quote isn't properly dealt with sometimes. If this is the case, the solution I've used is to tell perl to not do Unicode (5.8.0 has a fairly buggy Unicode implementation) by putting "use bytes" at the top of the script. -- Randomly Generated Tagline: "It's not that we're afraid ...

Re: [Wlug] Perl puzzle solved

by douglas.r.aker＠verizon.com

Thanks Jared and Frank for your quick responses. The solution, it turns out, had nothing to do with RE's, but rather with input lines and files. I'm dealing with multi-line, comma-separated-value records, using Perl programs to convert them to single line records, change bare carriage-return characters to newline characters and eventually remove extraneous trailing commas, e.g. ...,"Moe, Larry, Curly, ",... (the comma and space after "Curly" is extraneous). I guess you can only do so much in one pass through an input file. The solution was to write two Perl programs, and use a two-stage process as in: cat multi-line-input-records | makethemsinglelines.pl | removetrailingcommas.pl > greatlookingfile.out Thanks again, Doug "Frank Sweetser" <fs(a)WPI.EDU> Sent by: wlug-bounces(a)mail.wlug.org 03/01/2006 09:40 AM Please respond to "Worcester Linux Users Group" <wlug(a)mail.wlug.org> To "Worcester Linux Users Group" <wlug(a)mail.wlug.org> cc Subject Re: [Wlug] Perl puzzle On Wed, Mar 01, 2006 at 09:30:26AM -0500, douglas.r.aker(a)verizon.com wrote: > The obvious s/, "/"/g doesn't work, nor does escaping the > double-quotes, as in s/, \"/\"/g Try $target =~ s/,\s\"/\"/g; -- Frank Sweetser fs at wpi.edu | For every problem, there is a solution that WPI Network Engineer | is simple, elegant, and wrong. - HL Mencken GPG fingerprint = 6174 1257 129E 0D21 D8D4 E8A3 8E39 29E3 E2E8 8CEC _______________________________________________ Wlug mailing list Wlug(a)mail.wlug.org http://mail.wlug.org/mailman/listinfo/wlug

Did you try escaping the comma?

Perl puzzle

by douglas.r.aker＠verizon.com

Hi. I've been spending far too much time trying to accomplish a (seemingly) simple thing: use a Perl substitution operation to replace, a comma followed by a space followed by a single double-quote with a single double-quote. The obvious s/, "/"/g doesn't work, nor does escaping the double-quotes, as in s/, \"/\"/g I must have tried dozens of variations. RE's can be tough at times. Late last night I had to admit defeat. Any ideas? Thanks, Doug
