I “finally” signed up for twitter last night. I put “finally” in quotation marks because while all of the geek blogs in my RSS reader have been raving about it for months now, I can’t think of a single person that I know that would actually have any idea what it is. “So, it’s kinda like Facebook, but without getting 200 ‘Generic Crime Family Game’ invites a day?” So for now I’ve just subscribed to people that I would *like* to know - like Cory Doctorow and Xeni Jardin from BoingBoing, Linus Torvalds…yeah, that pretty much completes my list so far.

I’m trying to figure out how the twitter RSS feed is going to look. It seems like more than a handful of people twiting could end up being pretty high-volume, so I don’t know if it’s worth it. I suppose time will tell…

A command-line tool that I wrote for running commands on multiple machines as root over ssh - rsudo - is now available on SourceForge. Hopefully this project will fare a little better than clutch did; rsudo has the twin benefits of being useful to someone now (as opposed to being a “solution in search of a problem”, as clutch was) as well as actually being used in a production environment for the last couple of years (note the Production/Stable development status). So, if you find yourself needing to run commands as root on multiple remote machines (don’t we all? ;-) ) then check it out!

Maybe I shouldn’t look at the news this early when I can’t sleep. Then again, maybe I should read it more carefully. I don’t pretend to have a full understanding of the situation, but the current state of the US economy is starting to kinda freak me out. It’s like all of the major financial institutions were duped by some kind of elaborate Ponzi scheme. When viewed from a certain angle in the correct circumstances - e.g., economic collapse - the similarities between a Ponzi scheme and the stock market are striking.

Despite the numerous possibilities, I’m only posting this link (for posterity). Laziness? Perhaps. …but if you’ve opened any newspaper, gone to any news website, or otherwise tuned into any kind of news outlet in the past few months I think you know what I’m talking about. The thing I’m trying to figure out (as indicated by this post’s title): who benefits? The scheme really isn’t a good one if the “mastermind” doesn’t walk away with a ton of cash, right? So…who is Charles Ponzi here?

I came across this amusing post on the dimensions of the World of Warcraft today (thank God for BoingBoing!). Some of the methods employed are questionable (one commenter noted that using Blink would be a *much* better way of gaging distances) but it’s good for a laugh.

The longest straight, flat line that an adult human can walk in Azeroth without being interrupted by obstacles, mobs or the Horde stretches from the eastern end of the north parapet of the bridge into Westfall, across Elwynn Forest to the southernmost of the Three Corners in Lakeshire. An adult human walking at a steady pace will cover this distance in 18 minutes and 15 seconds. Humans walk at an average speed of 5.6 kilometres (3.5 miles) per hour, and therefore this route is roughly 1.7 kms (1.05 miles) long.

Someone drew my attention to The Noob Comic the other day, and I ended up spending the next hour or two “catching up” (there are over 300 comics in the series at present). It’s a must-read for anyone who has ever played (or thought about playing) an MMO. I think I actually laughed out loud when I read the Arsemode comic

Difference Engine No. 2My God…this thing is just incredible. …and there’s actually a video of it working!

Colossal Cave meets nerd humor; this is fantastic stuff: The Mathematical Grue. Non-nerds needn’t apply. Just to give you a taste:

You are sitting before a particularly thorny conjecture.
Possible proofs lead away from here in several directions.

You are carrying the following items:
A ream of blank paper
A pencil
The Cauchy-Schwarz inequality
Some half-remembered undergraduate mathematics

Whew! A busy two weeks, to be sure. First: the “old news”. I recently discovered the excellent open source app Synergy. Synergy

“…lets you easily share a single mouse and keyboard between multiple computers with different operating systems, each with its own display, without special hardware. It’s intended for users with multiple computers on their desk since each system uses its own monitor(s).”

Wow. This is about the best thing since sliced bread for anyone with multiple machines (possibly running multiple OSes, no less). …and I have…well…a few machines.

Next up: Pandora, an online music service. “What’s so great about that?” you ask? Well, Pandora allows you to search for a song or artist, then creates a “station” for you that plays other songs/artists that are similar. This is beyond fantastic, and (apparently) has been around for quite a while now without my managing to catch wind of it. Kudos, Pandora!

Finally, in a fitting follow-up to my last post, Google has found a way to burrow even deeper into my daily routine. To be more specific, GMail now supports IMAP. I’ve been waiting for this for a long time, folks, (as have a lot of other nerds who actually know what IMAP is) and it’s finally arrived.

As a systems engineer, I pride myself on knowing “a lotta things about a lotta things”. One of the questions that I was asked in the interview for my current position was “What do you define ‘engineer’ to mean?” My response was something along the lines of, “Someone who is capable of solving the problem at hand, who either has/knows the proper solution or has the capability to find the tools to solve the problem.” I still think this is as reasonable a generic description as any, although there are obviously other more formal descriptions available.

In this context, I’ve often found it interesting to observe the work habits of the people I work with. Most of them are older than I am, and most if not all of them are equally capable of solving problems just as I am. However, there are a couple of major differences that I’ve noted. One is a dependence on books as reference materials. I think I have one book in my office at work - an old and dusty book on C data structures that was likely left there by one of my predecessors. Don’t take that in the wrong way; I’m not undermining books as a useful training and/or reference tool, they simply aren’t generally a part of my daily workflow.

Another interesting phenomenon that I’ve noticed - particularly with those employees that used to be in consulting - is an emphasis on professional certifications. Personally, I don’t put a whole lot of stock in professional certifications. Perhaps that’s because I don’t have any, but with few exceptions I see them more as “gold stars” to put on one’s resume than as being indicative of one’s capabilities as an engineer. The people who I work with are good at what they do because they’ve got good heads on their shoulders and because they have been doing what they do for several years, not because CompTIA said they were good at it. (As an aside, I would like to become a Certified Beer Judge…but that’s a subject for another post).

So, if I don’t use books and I’m not “certified”, how do I get things done? Well, there’s the aforementioned “know a lotta things” approach, but that only goes so far. Then, as a Unix sysadmin I’m fully capable of using all the tools therein - man pages, grepping through files in /usr/share/doc, etc. But after that? You guessed it…Google. I would generify that last statement by saying “online search” instead, but that would make it a bit less accurate. I don’t use “online search engines”; I use Google. Exclusively. Without hesitation or reservation, and generally without even considering using some other tool or site to find the information that I need. Just Google. It’s my default page when I fire up a browser window. It’s the first link in the single bar of links and folders that I allow myself in an otherwise fairly spartan browser configuration. In fact, a fairly large percentage of is dedicated to link icons for Google’s various services.

What’s my point? Well, I was contemplating what a Day Without Google would be like for me. What if Google just ceased to exist, or (horrors!) started actually trying to charge me for the invaluable services that they’ve graciously provided thus far gratis? No more GMail - my primary account for things not work related; back to Hotmail. No more Google Notebooks for tracking ToDo lists, certain contacts, and progress on various projects; back to pen-and-paper or Notepad, or the ever-popular “I’ll just remember it”. No more Google Reader for aggregating feeds for my daily news fix; back to Bloglines (which is less-than-terrifying) or *shudder* simply refreshing /. 200 times a day. No more Google Docs - perhaps the most useful app that Google has released thus far (and as yet one of the more underused…by me, at least). And, of course, the most important loss of all if Google were to disappear overnight: no more Googling.

Terrifying, no? It is for me. I don’t know what’s scarier, actually - the thought of Google going away, or the fact that I’m so completely dependent upon a single company for providing so many of the useful services that I use every day. They don’t have all of my data, but they sure have a lot of it, and that’s a bit troublesome for those of us that worry about these kinds of things on a day-to-day basis. Thus, I’ve thought it would be an interesting experiment to try living for a day without using any Google services. Don’t hold your breath - I’m not sure I’m even going to do it yet, let alone going Google-less any time soon. it’s just an idea that I’ve been kicking around in my head. If you know of anyone who’s done this (and lived to blog the tale :-) ) be sure to let me know in the comments so I can figure out what I’d be in for…
