Kevin Mitnick & Social Networking Tools

2009-11-17T14:05:00.000-08:00

A hacker by the name of Kevin Mitnick was arrested in February of 1995 by the FBI. He spent the next eight months in solitary confinement because law enforcement officials were able to convince a judge that he had the ability to start a nuclear war by simply whistling into the phone.

They eventually let Mr. Mitnick out of solitary, and a few years later he was let out of jail. A few years after that he gave a very interesting and insightful speech at Carnegie Mellon, which I was fortunate enough to attend. During his talk he focused on how humans are always the weakest link in any system's security. His speciality wasn't being a master whistler, but rather being a master con artist. He was an expert at what is known as social engineering--tricking people into giving him their passwords and user names. In other words, computer hacking at the end of the day is as much about people as it is about technology.

This brings me to my point. Many people seem to have forgotten that social networking tools like Facebook and LinkedIn are tools for connecting with real people for forming real relationships. Too many executives, activitists, and organizers have become enamored with social networks as technologies. They focus on their virtual presence and neglect the importance of building real relationships with their target audiences. Just as too many CTOs and CIOs focus on improving the security of their systems through technological means and neglect to teach their employees how to resist con artists.

Scotch in the Antartic.

2009-11-16T10:54:00.000-08:00

According to this article on Yahoo! a couple of cases of McKinlay and Co. scotch whiskey have been entombed in ice in Antarctica underneath Sir Schackleton's hut for the last 100 years. The beverage company Whyte & Mackay, which owns the rights to the McKinlay and Co. name, is mounting an expedition to retrieve some of these bottles in order to decide whether or not to relauch the brand.

Does this sound like a load of BS to anyone else? I'm pretty sure that this is the flimsiest excuse in history for launching an expedition to Antartica. Well maybe not the absolute flimsiest, but it's definetly in the top ten. I'm pretty sure this was an idea that was hatched during a whiskey "tasting."

Actually, on closer inspection the idea is brilliant. In 2006 workers restoring Sir Schackleton's hut discover the whiskey. The executives and McKinlay and co see an opporutnity to revivie an old brand, give it a truely romatic image and make lots of moolah. The trick of course is tie the brand to romatic images of Sir Shackleton and antartica. Which is exactly what a modern day expedition to retrieve the bottles does.

Brilliant!

Annual Scotch Tasting!

2009-11-13T09:50:00.000-08:00

Last night was the Georgetown Alumni club's annual scotch tasting. Being a fan of scotch, I had no choice but to go; and as usual, I had a fantastic time.

This year the event was held at a small capital hill cocktail bar--Wisdom. I though the bar had an interesting vibe and an eclectic cocktail menu. It was very heavy on gin and absinthe based drinks. My only real complaint about the bar was it's location. It was out in the boondocks. Well not really, it was on the eastern side of Capital Hill which to me is the boondocks. I never go out there.

Anyways, I attended the event with a friend of mine from grad school. We had initially planned to meet for dinner before the event. However, horrible DC traffic derailed that plan. So by the time we finally managed to meet up it was 7:30pm. Since the event was scheduled to start at 8pm and head straight to the bar.

Once we arrived at the bar we realized that we probably shouldn't drink a ton of hard liquor without having some food in our stomachs. So we ordered some hummos. The dish we got was nothing to write home about. So I won't bore you with the details.

The bartenders at Wisdom created three scotch based cocktails to accompany the tasting. I tried one that was mixture of port, vermouth, and scotch. My friend tried another that was a mixture of absinthe, pineapple, and scotch. Both were excellent. Apparently, scotch is a good base for a complex cocktail.

The format of the event was bit chaotic. I guess the initial plan had been for Glenfiddich to send out a number of folks to the bar who would walk everyone through four different scotches the 12,15,18 and 21 year old. Unfortunately, only one person was sent out. They decided to do cycle people through the tasting in batches of three. Naturally, this was a mess. But by that point in the evening we didn't mind the inefficencies of the process.

Relearning Mathematics!

2009-11-11T09:52:00.000-08:00

I used to know a fair amount of math. I earned a minor in mathematics as well as a degree in computer science. So, at some point I was pretty well versed in math.

These days, however, I'm lucky to be able to add two numbers together correctly! What happened? Well, apparently, if you don't exercise your math muscles you lose them.

So, I've decided my current mathematical illiteracy is unacceptable. I've decided that I'm going to go back and relearn all the math I've forgotten.

As a first step, I went to the library and checked out Concrete Mathematics by Knuth et al. I've been told that this a classic text that all good computer programmers should have read. Needless to say, I've never read it.

I've been slogging my way through the book for a few weeks now. I'm only 4 chapters in and I don't think I've gotten a single problem correct yet. That's probably an exaggeration, but only a small one. What I've come to realize is that I've forogotten how to thing mathematically.

Mathematical thinking is a very specific kind of cognitive process. It requires the strict, almost mechanical application, application of logic. In other words, it's a mode of thinking that has almost no use in our daily lives.

So, the question I'm grappling with is: Is it worth relearning how to think mathematically?

Is Facebook making us less social?

2009-11-10T07:21:00.000-08:00

One of the things I've been thinking about is whether or not social networking tools are simultaneously increasing the number of relationships we're able to maintain and decreasing the depth of each relationship.

For example, someone I went to high school with got engaged this morning. They posted this information to Facebook. A number of people responded to this post with a congratulatory note.

I considered doing so as well. However, in the end I didn't feel that it was really appropriate. While, I'm 'friends' with this person I have talked to her in nearly nine years. A congratulations from me would be a hollow social gesture, completely devoid of meaning.

So are tools like Facebook making more and more of our social interactions hollow and meaningless?

Pomodoro Technqiue

2009-11-09T07:11:00.000-08:00

During the panel discussion at the NFJS conference on Sunday one of the panelists mentioned the Pomodoro Technique for getting things done.

Basically it consists of doing the following :

Choose a task to be accomplished
Set the Pomodoro to 25 minutes (the Pomodoro is the timer)
Work on the task until the Pomodoro rings, then put a check on your sheet of paper
Take a short break (5 minutes is OK)
Every 4 Pomodoros take a longer break

My understanding is that you are suppose to make a dash (vs a check) on your sheet of paper, if you fail to work on the selected task for the full 25 minutes.

The basic goal of the Pomodoro technique is to lengthen your attention span. If your like me, you've developed a number of bad habits over the years:checking email constantly, chatting on IM, constantly checking google reader... The Pomodoro technique is meant to help you break some of these bad habits.

How does it work? I don't know. I'm not even sure I'm going to try it.

What I would like to do, and I'll add this to my ever grown list of potential projects, is build some software times that are geared toward this particular productivity method.

Trying something different.

2009-11-09T06:54:00.000-08:00

I've decided that for the next 30 days I'm going to post something on here. I've also decided that I'm not going to start with an "anchor" as is traditional of many blog posts.

The classic formula for a blog post is to start with a news article, another blog post, or something else that you've ran across on the web and to respond to that thing in some way. For example many blog posts follow this format:

Blogger X has a really interesting post up this morning on Subject Y. I have to agree/disagree with him/her strongly. Let me tell you why: ...

While this format has the advantage of "injecting" you into an existing debate and possibly driving traffic to your site through the linkbacks. It doesn't really give you freedom to explore topics that interest you.

It also reduces the amount of thought an creativity you have to invest into a blog post. In many cases this is not a bad thing: I'm less likely to write something if I have to start from scratch.

However, I've come to realize that one of the reasons I want to have a blog is to give myself a space to "think out loud." So I'm going to force myself to do that by putting up at least one post a day that's completely free form.

Let's see how it goes.

Sprint outlaws tethering.

2009-11-04T10:52:00.001-08:00

Apparently Sprint will no longer allow tethering. The use of your cell phone's Internet connection by your laptop. There are three reasons I use Sprint: their plans structure is simple, they allow tethering, and they have free roaming. While the loss of tethering isn't a deal breaker for me, I am disappointed in Sprint's decision.

Shiny Objects.

2009-09-29T13:24:00.000-07:00

Lately, I've been in the mood to learn about some new technologies. For the past few months, year I've been fairly head down in the J2EE world learning/using J2EE technologies like EJBs, JMS, Spring, etc... Now I'd like to use some time to branch out and look at some none J2EE technologies.

I find that it's important spend some time outside of your comfort zone every once in a while. Like all technologies the J2EE world expects you to modify your thinking to fit within a certain framework. The more time you spend working within that framework the harder it becomes to think in a different way. One way to keep your mind nimble is to, every once in a while, try something new.

However, learning a new technology with out the pressure of deadlines or the structure of a project to work within is an incredibly frustrating process. When you are learning a technology in order to accomplish a goal, it's very easy to stay focused. You figure out very quickly what's important and what isn't. When your goal is to learn a technology it's very hard to stay focused. To keep from being distracted by every shiny object that you wander across.

Some people blithely suggest, why don't you simply formulate a project and use that project as a learning tool. Formulating a project is difficult. You have to find something that is simultaneously interesting, unimportant, and straight forward. These attributes seem to me to be inherently contradictory.

So the question arises, what is the best way to learn a technology?

Undirected Reading aka Web Surfing.

2009-09-28T10:13:00.000-07:00

When things get slow at work I, like most people, surf the web. While some may look view this as a waste of time, I'm more inclined to view it is an important professional development activity.

First, rather than referring to it as web surfing let's call it undirected reading. If you think about it, most of the things we read in life fall into two general categories: stuff we need to read for work, stuff we want to read for fun. However, surfing the web really doesn't fall into either of those categories. Rather, surfing the web is process of discovering what we want to read for fun and what we should read for work.

I'd say, without any statistical basis, that ninety-nine percent of what I read when I surfing the web is neither fun nor useful. Mostly, it's just junk. However, the act of filtering through this great mass of junk does help me clarify my thinking in some hard to define way. It helps me figure out what I'm really interested in.

My First post.

2009-09-23T10:32:00.000-07:00

I've tried blogging several times and I've never been able to stick with it. Let's see if this time is any different.

It customary, as customary as anything on the web is, to start your blog with a statement of intent. To layout why you are blogging, what you intend to blog about and who you'd like to read the blog. So here goes:

1. I'm blogging because I'm hopeful it will help me sort through the barrage of ideas that I'm exposed to every day. I hope it'll help me clarify my thinking and it'll give me a outlet to improve my writing.

2. I intend to blog primary about technology, the books I read, and the daily challenges of my life.

3. Primary, I'd like my friends, colleagues and peers to read this blog.

This attempt at blogging will be a bit more ambitious than my previous attempts. This time I'm actually creating two blogs: a general interest blog(karthikthinks.blogspot.com) and a technical blog (karthikcodes.blogsport.com.)

Check out Karthik Codes to learn more about that blog.
