Odd Perl Hacks

For my senior project in my last two semesters at the University of Colorado myself and two others were tasked to create a web-based scheduling system for the Conference on World Affairs. This seemed like a trivial task, except we were lacking some serious tools. For one, we had no access to a database (no MySQL, Oracle, etc.) and the only language we could could use was Perl 5.6 with no modules. This was due to the fact that the system had to reside on the main university server, an old Solaris 8 V880, which is shared by most of the departments across the campus. Consequently, we had to build a database from scratch using text files while maintaining relational database concepts such as primary/foreign key constraints, atomic writes, and encryption. It also needed to support multiple years for each new conference, up to 200 panels a year, up to 100 panelists, along with coordinators and moderators for each panel. A conflict detection mechanism was necessary to discover problems with the schedule (one person in two places at the same time sort of thing). Additionally, a user account system was needed to allow only authorized people to use the scheduler.

It was an immensly complicated project that took about 10k lines of Perl to accomplish, which in the mind of ESR was probably way too much. It did, however, give me great insight onto why existing tools are so important along with a deep appreciation of modern relational databases. And our team even won an award for the project. Along the way, I also learned and created some neat Perl hacks to solve the problems with writing (and rewriting) a development library. Let me show you some tricks.

Round Up A Number

sub roundUp()
{
    # Calculates number of pages needed when a decimal place screws things up

    ($n)=@_;
    return(($n == int($n)) ? $n : int($n + 1))
}

Isolate Calendar Week

sub convertDaytoDate()
{
    # Used to determine conference day of week without need
    # of unnecessary db storage.

    ($day,$year)=@_;

    # Isolate April using UNIX cal
    $cal=`cal 4 $year`;
    @cal = split("\n",$cal);

    # Grab the 2nd week of April
    $interest = $cal[3];
    $interest =~ s/(^....)//;
    $interest =~ s/\ \ /\ /g;
    @days = split("\ ",$interest);

    if ($day =~ /Monday/) { $DD = $days[0]; }
    if ($day =~ /Tuesday/) { $DD = $days[1]; }
    if ($day =~ /Wednesday/) { $DD = $days[2]; }
    if ($day =~ /Thursday/) { $DD = $days[3]; }
    if ($day =~ /Friday/) { $DD = $days[4]; }

    return("April $DD, $year");
}

Convert Non-ASCII Characters

foreach $entry (@cwaparttable)
{
    chomp($entry);
    $entry =~ s/(.)/checkForNonASCII($1)/eg;
}

sub checkForNonASCII()
{
    # Eliminates foreign letters, character by character

    if (ord($_[0]) < 128){
        # ASCII
        return $_[0];
    } else {
        # Non-ASCII
        return sprintf('&#x%04X;', ord($_[0]));
    }
}

APC UPS on OpenSolaris (apcupsd)

One of the best consumer UPS manufacturer on the market is APC. They make great products that can interface nicely with any UNIX-based system, whether it be Linux, BSD, or Solaris. Using their daemon (apcupsd), you can download the source and create a nice link-up with your UPS so you can be notified anytime your power goes out (or if you accidentally unplug it)

My home model is the APC ES550 which is USB-based and has a weird USB->RJ45 cable to link a computer with the UPS. Let me explain how to get this running with OpenSolaris with at least this model.

First you will need the latest apcupsd tarball located on Source Forge. Then, follow some standard compiling directions:

    $ tar zxvf apcupsd-3.14.4.tar.gz && cd apcupsd-3.14.4
    $ ./configure --enable-usb
    $ make
    # make install

libusb.h:9:34: /usr/sfw/include/usb.h: No such file or directory
... lots of errors ...

'make' fails on OpenSolaris because by default it is missing a usb.h header file located in /usr/sfw/include. This can be retrieved by running this command inside that directory as root.

    # wget http://src.opensolaris.org/source/raw/sfw/usr/src/lib/libusb/inc/usb.h

The file apcupsd.conf is needed to configure this USB device. Two lines that say the following must be included in this file.

UPSCABLE usb
UPSTYPE usb

Now, you should be able to run the daemon and you can verify that it will notify you by simply pulling the plug on the UPS. If you modify your root alias in /etc/mail/aliases the UPS will send you an e-mail when the power goes out. This sounds handy if I'm campus and I lose the electricity in my apartment, so I'll have plenty of time to power off my machine remotely.

ZFS NAS with the Intel Atom

I've been looking to build a network attached storage (NAS) device for some time to store all my music, photos, films, etc. in one global location. I had a few specific requirements that were as follows:

[root@bojangles ~]# zpool attach tank ad4s1d ad6s1d

[root@bojangles ~]# zpool list
NAME                    SIZE    USED   AVAIL    CAP  HEALTH     ALTROOT
tank                    928G   72.9G    855G     7%  ONLINE     -
[root@bojangles ~]# zpool status
  pool: tank
 state: ONLINE
 scrub: none requested
config:

	NAME        STATE     READ WRITE CKSUM

	    ad6s1d  ONLINE       0     0     0

errors: No known data errors

[root@bojangles ~]# cd /usr/ports/net/samba3 && make install clean
[root@bojangles ~]# cd /usr/ports/net/ushare && make install clean

What?
