The MacUpdate Bundle

Hmmm -- was going to buy iWOW tomorrow for $20, but for $50 this bundle looks like the better way to go...  I'm sure I can get my $30 worth out of PulpMotion and iStabilize, even if I never use some of the others.

"Your Deal: The Mac community has triumphantly come together reaching all of the unlock milestones before the unlock countdown expired. Now when you buy this bundle, you become the owner of all 11 applications immediately: PulpMotion, XMIND 2008 Pro, iStabilize, Forklift, RapidWeaver, Swift Publisher, Marine Aquarium, Xslimmer, MemoryMiner Yep, and iWOW 2."

New communication technique?

Type only things that require a single hand, despite using QWERTY (punctuation doesn't count for this exercise, because silly unreadable run-ons aren't nearly as fun...):

Examples from an xkcd "blag" post:

• “We fear a few dwarf watercraft stewardesses were regarded as desegregated after a great Texas tweezer war.”
  
• “I’ll kill him in Honolulu, you unhook my pink kimono.”
  

Here are my "left-handed" remarks (which are perfect for right-handed mouse-o-philes):

• "Are extra trees ever great weeds?"
• "Car was safe: waxed, gassed, etc."
  
• "A feat: create vast reverberated waves!"
• "Ever see a bad feast? Excess sweet treats?"
• "Draft? Wear a sweater."
• "Axe a rat; feed face; get a barf bag, fast!"
  

May have to get a Treo...

Treo 750 gets WM6 and HSDPA, finally. Even a free download for AT&T versions on the Palm site... Now, I just need to find out when my current plan dies. Don't really think I want to spend the $550 for the unlocked version, but will have to compare and contrast before making a decision on what and when to buy. Also kinda interested in the BlackJack II, but like the idea of being able to use the same bluetooth receiver and an updated version of the GPS software I've been using on my WM5 PPC.

GigaPan-tastic

Hopefully, the consumer GigaPan robotic mount will come out of beta soon, but will have a cost similar to its sub-$300 beta price. Sure, you can accomplish the same thing manually, but having a motorized automated mount would be pretty darn wicked! It's also pretty cool that you can browse a growing library of these interactive images not only on the GigaPan site, but also in Google Earth (minimum version 4.2).

Free Vectorization Utility

Stanford University's Vector Magic lets you make a vector-based (EPS or SVG) from your image files -- scale away happily after converting...

More on bash, arrays, and index values

So, if you "man bash", you will see the following:

Arrays
Bash provides one-dimensional array variables. Any variable may be
used as an array; the declare builtin will explicitly declare an array.
There is no maximum limit on the size of an array, nor any requirement
that members be indexed or assigned contiguously. Arrays are indexed
using integers and are zero-based.
...
Any element of an array may be referenced using ${name[subscript]}.
...
${#name[subscript]} expands to the length of ${name[subscript]}. If subscript is * or @,
the expansion is the number of elements in the array.
...
The unset builtin is used to destroy arrays. unset name[subscript]
destroys the array element at index subscript. unset name, where name
is an array, or unset name[subscript], where subscript is * or @,
removes the entire array.

What does all that mean? It means that index values don't get reset when you unset array elements, so you shouldn't rely on ${#name[*]} in loops, unless you know that the index values are contiguous. So, if you want to loop based on the number of elements, you had better reset the index values by using something like: name=(`echo ${name[*]}`)

Copy and paste the following into a file, and then run it using your favorite implementation of bash (Cygwin, OS X, Linux, BSD, etc.) to see how it all works:

#!/bin/bash
function show_array {
echo There are ${#NUMBERS[*]} numbers in the array.
echo The index positions and values are:
IDX=0
while [ $IDX -lt ${#NUMBERS[*]} ]; do
echo -e $IDX \\t ${NUMBERS[$IDX]}
let IDX+=1
done
}
function pause () {
read -p "$*"
}
echo Bash Shell Array Element Index Handling
echo ----------------------------------------
NUMBERS=(zero one two three four five six seven eight nine)
show_array
pause "Press Enter "
echo ----
echo Now, let\'s unset number five, and see what happens...
unset NUMBERS[5]
show_array
echo Eek!, looks like there\'s a NULL element in there.
echo So, the number of elements has been reset, but the indexing has not.
echo Indexing is non-contiguous by design, so this isn\'t a bug. However,
echo this means that we do not get to see all of the elements if we are
echo looping based on the number of elements in the array.
pause "Press Enter "
echo ----
echo Let\'s try to unset number 1 this time...
unset NUMBERS[1]
show_array
echo Looks like there\'s another NULL element in there, now.
echo Again, the number of elements has been reset, but the indexing has not...
echo The \${#NUMBERS[*]} does not count NULLs, but index values do not
echo change. The while loop produces apparent garbage after some elements
echo have been unset.
pause "Press Enter "
echo ----
echo Enter the cheesy work-around:
echo "It looks like this: NUMBERS=(\`echo \${NUMBERS[*]}\`)"
echo This kills the NULL values and resets the indexing so it is
echo contiguous again...
NUMBERS=(`echo ${NUMBERS[*]}`)
show_array

Happy bash-ing...

GPG Extension for Firefox!

FireGPG is a Firefox browser extension that can handle crypto tasks. I'm going to have to try to integrate this with my "Portable Apps" install of Firefox so that I can use crypto on Gmail and Hotmail from anywhere... Looking forward to trying it out this evening!

Update: Seems to work just fine -- both for encrypting and decrypting. I had to over-ride the default keychain location for GPG and the default GPG location for the extension... Will need to try from a different machine to be completely sure, but I think I've nailed it!

Rejected Ubuntu Release Names

As I pointed out previously, Ubuntu Releases have all been alliterative animal phrases. While the initial two releases were "Warty Warthog," and "Hoary Hedgehog," the adjectives in these phrases have become somewhat more flattering since, featuring: Breezy, Dapper, Edgy, Feisty, and (currently) Gutsy. With this trend in mind, it is fun to imagine some of the submissions that may have been received and rejected by the Ubuntu team. I submit the following alphabetically-aligned alliterative adjective/animal amalgamations that are unlikely to ever be associated with any project or product:

Acrid Amoeba Bald Beaver Cantankerous Cub Devilish Dromedary Evil Elk Fearsome Frog Geriatric Grunion Heinous Hippo Illiterate Ibis Jacobite Joey Killer Kite Lame Llama Mongoloid Mongoose

Noisome Nit Onerous Orangutan Precarious Porpoise Queer Quokka Rabid Rat Sterile Serpent Twisted Trout Urbane Ungulate Voluptuous Vixen Warlike Walrus Xenophobic "X-animal" Yucky Yak Zero-sum Zebrafish

Virtual Gutsy

Updated my Ubuntu 7.04 (Feisty Fawn) virtual machine to 7.10 (Gutsy Gibbon) -- nice and smooth via the network install. Since it's in a VM, I don't see the fancy 3D interface elements. C'est la vie...

In other Ubuntu news, the next version has already been given a name (Hardy Heron). I would like to be the first to propose the following properly alliterative animals for future versions:

• Intrepid Iguana
• Jocund Jackal
• Kinetic Kangaroo
• Lively Lemur
• Merry Marmot
• Nifty Newt
  
• Obliging Ocelot
  
• Puissant Puma
• Quintessential Quail
• Robust Raccoon

That ought to last a couple of years...

Thanks xkcd, this is just too funny...

Array Variables in bash

In my efforts to improve my NTFS-3G mount/re-mount script, I had to learn how to implement an array variable. Turns out it's painfully simple, and now I feel that I should go back and eradicate the evil temporary files that I used in some of my earlier quickly-generated scripts. But, I digress... Here are some quick basics that proved useful:

• Array variables can be implicitly declared, e.g. PETS=(dog cat bird fish) builds a four-element array.
• To show the whole array, use ${PETS[*]}
  
• To show the number of elements in the array, use ${#PETS[*]}
• Element index starts at zero so ${PETS[1]} will return cat

Here's the sample code that I threw together to make sure I figured it out properly, with comments added in a different font to explain each line of the script:

#!/bin/bash
# build an array of partitions (OS X), populated only with disk#s# for each partition
TEST=(`diskutil list | egrep disk.s. | awk '{print $NF}'`)
PARTS=0
# Build a menu that shows each partition in the array
# but start numbering at 1 instead of 0
while [ $PARTS -lt ${#TEST[*]} ]; do
let COUNT=PARTS+1
echo "$COUNT".\) ${TEST[$PARTS]}
let PARTS+=1
done
# Prompt for / grab user input, and see if it matches something on the menu
echo -n Please select a partition from the menu above:
read TRYIT
case $TRYIT in
[1-${#TEST[*]}])
# NOTE: [1-3]is an expression that matches 1, 2, or 3...
echo You typed a valid number: $TRYIT;;
*)
echo You typed a bad number: $TRYIT;
exit 100; # set a non-zero exit code
esac

NTFS-3G Mount/Re-Mount Script for OS X

Requirements:

• MacFUSE Core Package
• NTFS-3G FUSE filesystem package

Features:

• Optional Command-Line Parameters:
• Partition to mount or re-mount (must be specified as the first parameter)
  
• Use the force option at mount (can be specified as either first or 2nd parameter)
  
• If no parameters are entered, script enters "interactive mode," and prompts user with a menu of confirmed NTFS partitions
  
• Handle volumes that are currently using the (read-only) kernel NTFS driver
• Prompt to unmount, custom exit level if user-aborted
  
• Capture name that is assigned in Finder
• Remount as read/write using the same Finder name
• Handle volumes that are not currently mounted
• Mount and assign a default Finder name: NTFS-disk#s#
  
• Input Sanitizing
• Volumes can be entered as "/dev/disk#s#" or (preferably) as "disk#s#"
• Script throws custom exit level if volume does not exist
• Script throws custom exit level if mount command fails due to non-NTFS volume
  
• Script throws custom exit level if it encounters NTFS-3G errors during mount
  
• (Possible Future Enhancements)
• Add a -? or --help option to the script for über-completeness
  
• Silent output -- rely only on the exit codes (Why? -- I can always redirect to /dev/null if I want to call it from within another script)
• Something I haven't thought of yet...
  

• bzip2 compressed version of the script (now includes updates through 1.4).

UPDATES
[Oct. 15] Version 1.1:

• Implemented volume-unique mount points, so more than one disk can be mounted
• Implemented menu (via array variable) for volume selection -- type a number instead of having to type disk#s#
  

[Oct. 16] Version 1.2:

• Implemented actual type detection using File System field from "diskutil info disk#s#"
  
• Previous method used reasonable speculation based on type field from "diskutil list"
• Learned that array index values can be non-contiguous, and are not changed when array elements are unset. (This led to a later post.)
  

[Oct. 19] Version 1.3:

• Added current mount point information to menu (yep, another array)
  
• Added header bar to menu
• Added Quit option to menu

[Oct. 27] Version 1.4:

• Implemented the file system type detection for volumes that are input from the command line.
  
• Previously, this was only implemented for volumes on the menu in "interactive mode."
  
• Added an exit level for "Not an NTFS Volume."

My Plate Runneth Over...

When discussing workloads, we often invoke the analogy of "the plate," and we talk about how "full" our plate is. In this context, we've been consistently reminded of the lessons of youth regarding the need to "clean our plate" at every meal; leaving the merest morsel of work uneaten is one of the few cardinal sins at the dinner table of employment. We're discouraged from over-committing ("take what you want, but finish what you take"), but the illusion that we have control over what we "take" repeatedly breaks down -- especially during "special," or difficult, times. (For now, we'll neglect that "difficult times" tend to become the norm when "Management by Crisis" is the foundational culture of the organization. This management technique, while outwardly easy -- because humans naturally seek leaders in a time of crisis -- is most often really a sign of a "crisis of management" caused by an endemic, and apparently irrevocable, lack of foresight.)

Allow me to extend the analogy of the plate, as it applies in "special times" -- regardless of whether such times have become the rule rather than the exception: Today is a special day, say, your birthday... Your family has taken you to a certain Amarillo steakhouse with a particular penchant for excess. Because you've been raised to "take what you want, but finish what you take," you order the 8 oz. sirloin. Your doctor would advise you to only consume 3-4 oz. of red meat during the course of a meal, but this is a "special day," and this particular steak is the 2nd-most humble slab of beef on the whole menu -- you wouldn't want to disappoint your family, after all. Well, it turns out that your family maintains their traditional values, and therefore can't pass up the opportunity to save some money ("waste not, want not"); so when you get up to wash your hands, your father calls over the wait staff and substitutes the *FREE* 72 oz. steak for your already-slightly-too-robust sirloin. Your meal arrives, and you protest that there clearly must have been some mistake, but your father calmly explains how much money you'll be saving for the family -- if only you can polish off four and a half pounds of beef in under an hour. Even though what your ordered would have cost $16 at the end of the meal, and this abomination costs $72 up front (refunded only if you complete the "challenge" successfully), your father smiles about how much money he is saving for the family, and encourages everyone to "dig in" to their meals. At that point you stop staring at your own plate for a moment and look around the table for the first time; you see that all of your siblings are facing a similar quandary. Since you're not alone, you feel obligated to try; since the clock is already inexorably counting down what remains of your precious hour, you suppress the urge to protest further and start cutting, piercing, shoveling, and chewing... Needless to say, there is an intrinsic -- but unstated -- requirement that you (and all of your siblings) rise to this challenge, lest the whole family should be forced to suffer as a result of your gastronomic ineptitude...

At least that's what seems to happen where I work...
