Perl best practices (was: question ... Split operator in Perl)

Well, this is something of a religious issue. :) But here's my opinion:
Personally, in the proper context, I find this:
@foo = split m{blah};
to be easier to read and comprehend at a glance than this:
@foo = split (m{blah}, $_);
The "proper context" being a loop or other pattern where I'm running
a series of operations on a series of inputs (i.e., lines). In those
contexts, where the whole point is to perform a series of operations
on each input, assembly-line fashion, using the the implicit argument
lets me focus on what the code is actually *doing*. Explicitly
specifying $_ over and over again just clutters up the code with
pointless syntax. It's one more thing my brain has to recognize and
process.
I don't arbitrarily assign to $_ and use it at random, the way some
people do. And I do make use of parenthesis, braces, and such, even
when they are not needed, when I find it makes the code clearer. But
I also leave them out when I find it makes the code clearer.
For a slightly less contrived example, take a script which trims
leading and trailing whitespace from each line in an input file. I
already have one implementation, and I just wrote up another one.
Here's one of the possible implementations:
#!/usr/bin/perl
$filename = $ARGV[0];
if ($filename eq "") {
open(INPUTFILE, "<&STDIN");
}
else {
open(INPUTFILE, "< $filename") or die("could not open input file!");
}
while(not(eof(INPUTFILE))) {
$line = ;
$line =~ s/^[\x20\t]*//; # trim leading space
$line =~ s/[\x20\t]*$//; # trim trailing space
print($line);
}
And here is another possibility:
#!/usr/bin/perl -p
s/^[\x20\t]*//; # trim leading space
s/[\x20\t]*$//; # trim trailing space
Assuming the reader is familiar with the language, which do you
think will be easier/quicker to comprehend?
It may be true that someone who *isn't* familiar with Perl would
find it easier to puzzle out the meaning of the longer version. But I
don't find that a particularly compelling argument. I write Perl
programs with the assumption that the reader understands Perl, the
same way I am assuming readers of this message understand English. :)
This may mean Perl, as practiced, is harder to learn than a language
which is more rigid and always verbose. Many say similar things about
Unix. Or Emacs. :-) I'm don't argue that one approach is right and
the other wrong, but I do think that both approaches have their
merits.
YMMV.

Re: AMD Releases 900+ Pages Of GPU Specs
I find that interesting as well. My first experience with Linux was on Slackware 3. trying to get X working with my ATI rage 3D integrated graphics card... I spent many sleepless nights trying to get that to work, so needless to say ATI has always left a bitter taste in my mouth. :) In fact, if AMD hadn't bought ATI and ATI released specs on their own accord, they would get huge brownie points from me, but I don't know if I'd move as fast in terms of migrating to their chips; but with AMD backing them, a company I personally admire for fighting the good fight, they get my support as long as they keep on keepin' on. On a side note, I tried to email NVIDIA through their online customer support form to let them know "too little too late, you can keep your binary blobs"... unfortunately it was down (technically it said "this module isn't configured yet" or something to that effect), but I can guarantee this announcement (and the follow-through) are rattling a few cages. ;) On 9/12/07, Jon 'maddog' Hall <[EMAIL PROTECTED]> wrote: > Tony, > > As normal, I probably understated my enthusiasm for what AMD/ATI have > done.

Re: AMD Releases 900+ Pages Of GPU Specs
Tony, As normal, I probably understated my enthusiasm for what AMD/ATI have done. I do find it interesting that it seemed to take AMD buying ATI before this happened. AMD has long been a supporter of FOSS. They were one of the first sponsors of the Linux kernel summit. I also find it interesting that this seems to be "standards done right". While I am a little distressed that some of the specifications are sent out under NDA, this can sometimes be a legal/liability thing, to protect AMD/ATI from issues in the spec. Also I note in some of the articles that they acknowledge that some of the specs are not up to snuff, so they will be putting out "sample code" to show how it works. Finally, they say that they will continue to work on their close-source proprietary driver...for those people that want peak performance. :-) >From my experiences with Digital's proprietary X Window System servers many years ago, I could predict this someday coming to a close, as some of the best minds in the computer industry work together to make the FOSS drivers stellar.

I haven't touched an Intel product since the days of them charging over $500 for a processor. AMD came in and stomped them with their K7, and as long as AMD continues to do the Right Thing(tm), they will always have my support. I've already begun liquidating my NVIDIA stuff; even if they start releasing specs with no NDA, it's too little too late in my eyes.

On 9/12/07, Neil Joseph Schelly <[EMAIL PROTECTED]> wrote: > I'm sure that something like FiOS would be stable enough for us. Cable > seems a little unreliable ... To the best of my knowledge, all the Verizon FiOS and Comcast data services are "consumer class". They'll be pretty much similar in terms of expectation of reliability -- i.e., none. Note that I said *expectation* of reliability. Many of them end up being reasonably reliable for long lengths of time. But you cannot depend on it. The "Business" names they stick on some of them have more to do with billing than anything else. There are some AUP (Acceptable Usage Policy) differences between the residential and business contracts, but that's about it. In my experience, the reliability varies in practice, too. I suspect it may correlate with location. I've never had a problem with my Comcast feed at home, in 2+ years there. My previous residence had an Adelphia cable feed, and that was pretty shaky. As a consultant, I've had experience with customers with DSL or cable feeds, and I likewise saw both good and bad, but consistent at a given location. I have no direct experience with FiOS, but I've read similar stories (both good and bad) on the web. So, if DSL or FiOS would be "good enough" for your needs, but only cable is available in your area, I would suggest evaluating the cable service. Call the sales office and tell them you want to give a try, but will not touch it unless they do it without subscriber commitment. If it turns out to suck, cancel. If it is good enough, you win. Disclaimer: I hate Comcast, but I hate Verizon more. So I guess I'm biased in favor of Comcast. Sort of. > I'd settle for cheap and fast (symmetric), but Comcast did offer to sell me a 1.5 Mbit/sec symmetric connection. It was either $200 or $300 a month, I think.

In my case, however, safety is not, at least at this point, a primary concern. Chances are, once this is past development, I'll revoke the certificate, trash the key, and redo an entirely new one. In the meantime, I have found that you can actually remove the passphrase from the key easily enough with the standard openssl application. :-) -- -- Thomas ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Contradictory goals. The idea behind a passphrase is that someone who steals the key can't use it because the passphrase only exists in wetware (you brain). The idea behind unattended startup is wetware is not to be involved. You can put the passphrase in a file, of course, but then the attacker just steals the passphrase file. You haven't secured anything, you've just moved the problem around. Some people put the key on an external medium (say, a floppy diskette, CD-ROM, or USB flash drive), and physically remove the medium except during Apache startup. This means you're safer against a remote attack, but now someone still has to be there to do the medium attachment, and that someone can still use the medium to read the passphrase, so you might as well just tell them the passphrase. Or write it on a Post-It note and stick it to the CRT, along with instructions on how to type it in when the system is sitting there during boot prompting for it. -- Ben ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

I think the retry > succeeds. Right, because the auto-thingies all work by polling the device. So if they happen to be polling the device when wodim tries to open it, you get the warning. Then they close the present poll, and wodim retries, and it works. Then, during the middle of the write, they poll again, and kablooie. At least, that's my theory. -- Ben ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
SSL certs/keys and Apache
Anyone ever use a passphrase protected private key with apache, and found a way to provide the passkey safely to apache without requiring the passphrase be typed in each time the private key is used? -- -- Thomas ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

I think the retry succeeds.

I can switch to runlevel 3 and see if wodim works. That eliminates all of the GUI magic.

In the past, I've had trouble with those auto-media-detect-and-mount daemons trying to auto-mount a disc as I'm trying to write to it. I suspect you might be having the same problem, because of this in your wodim output: Error trying to open /dev/scd0 exclusively (Device or resource busy)... retrying in 1 second. Since I hate those auto-thingies anyway, I just killed them off, and renamed the binary to keep them from starting again. (Removing the package often isn't a good idea because the package may also provide a library other programs link against.) I remember the GNOME auto-thingy was called "MagicDev" at one time. I don't remember the name of the KDE auto-thingy, and I don't know if either of those might be using a new auto-thingy by now. (As of late, I'm running FVWM, which doesn't start auto-thingies by default anyway, so I don't have recent experience.) -- Ben ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
