The History of Tux the Linux Penguin

Linux - Tux

I ran into this on one of the RSS feeds I often read.  I never knew where the Linux penguin came from or the name its “TUX”.

“Tux” the Linux Penguin

(T)orvolds (U)ni(X) –> TUX!

Why a penguin?

  Linus Torvalds has always liked penguins.

11 Geeky Tips : What makes a good Information Technology geek? - Part 1

I was reading this blog over at Inter-Sections (blog: Inter-Sections » Blog Archive » How to recognize a good programmer) and some of the topics brought up I thought could be of value. I also thought that I would apply it SysAdmins and Technical Architects. I think these are good food for thought items People, jobs, and companies have all their own idiosyncrasies and these items are not the beginning or the end on hiring people.

Let’s start with some excerpts from Daniel’s blog entry.

#1 : Passion

Can you get this guy to excitedly chat up a technology that he’s using, for a whole half hour, without losing steam?

#2 : Self-teaching and love of learning

If you’re thinking of hiring someone as a programmer, and he ever utters the words “I can work with that, just send me on a training course for a week and I’ll be good at it”, don’t hire that guy. A good programmer doesn’t need a training course to learn a new technology.

#3 : Intelligence

In fact, good programmers are usually among the smartest people you know. Many of them will actually have pretty good social skills too. The cliché of the programmer who’s incapable of having a conversation is just that - a cliché.

#4 : Hidden experience

A good question to ask a potential “good programmer” in an interview would be “can you tell me about a personal project - even or especially one that’s completely irrelevant - that you did in your spare time, and that’s not on your CV?” If they can’t (unless their CV is 20 pages long), they’re probably not a good programmer.

#5 : Variety of technologies

Learning a new technology is one of the most fun things a programmer with any passion can do. So they’ll do it all the time, and accumulate a portfolio of things they’ve “played around with”. They may not be experts at all of them, but all decent programmers will be fluent in a large inventory of unrelated technologies.

#6 : Formal qualifications

The key point to outline here is that formal qualifications don’t mean squat when you’re trying to recognize a good programmer. Many good programmers will have a degree in Computer Science. Many won’t.

I have to say that these six points are very good and apply similarly to System Administrators and Technical Architects.  I want to add more thoughts around some of Daniel’s points and add some of my own as well. 

Passion & Hidden Experience

I do think that a good geek can talk your ears off about technology.  I also believe for the best, it is the continuation of a hobby or something they are good at.   This plays in line with #1 and #4 above.  I also think there has to be some amount of perfectionism or OCD as well.  I’m not talking about to the unhealthy levels, but a little bit of wanting it done 100% correct.  In my mind, the difference between a true geek and a manager is a geek doesn’t want to settle with something being 90% correct and a manager knows that with all projects, compromises will be made and nothing will be 100% right.  The geeks that get into trouble are the ones that are so fixated on the getting to 100% that nothing else matters.  I have seen geeks lose good jobs because they were okay with “burning a village in order to save it”.  Needless to say that these types of geeks would never survive in a management role.

Passion also comes out in discussing around choices on how to do something and how well they can convince others as well.  It can go too far with fixation about being “right” and wanting to beat people into submission but the exuberance about the choices is usually a positive trait.  You want a person that cares about quality of work and taking care of others.  The individuals who are, don’t want to discuss with or convince others and will settle for the path of least resistance is the people who shouldn’t be hired.  Nothing frustrates me more than those who ,“have turned being unengaged into a Zen-like thing.” , a quote from one of my favorite fictional characters

In regards to hidden experience, good Systems people tend to not view being a SysAdmin or Architect as a “day job” it is more like a part of them or more than just a vocation.  I would be cautious about the passion levels or commitment levels of those who aren’t interested or fiddle around with technologies outside the office.

Self-teaching and love of learning

I totally agree with point #2.  With the tempos of projects individuals who insist on always having a training class before wanting to work with something typically is going to be trouble.  I do believe in training classes and believe that a company should provide people with training.  However, my experience has taught me that most people use this as an excuse or as a crutch so they do not have to support or learn something.  I have found that I always want to learn something about and how to use technologies before I go to the training classes.  I have found that understanding many aspects of the technology beforehand helps get the most value for me out of a training class.  I have also seen some of the “gotta have the classes” individuals are the same that have more initials after their name than my medical doctor does.  It could be that they want to milk the company for as many certifications as possible so they can go somewhere else and get paid more.

Variety of Technology

I think senior people should have a variety of experiences.  I think that some experience in different disciplines is excellent as well. (e.g. SysAdmin, Security, Network Admin, Management, Project Management)  For more of my thoughts and pontifications on career paths see this post.  I also want to place technology biases in this category as well.  We all use technologies and products that we are all comfortable with and the natural tendency is for us to reach for those tools whenever we have a problem to solve.  That’s normal and natural but that is not exactly what I’m talking about.  It’s the folks who flat refuse to work with Microsoft Windows, or think that mainframes are dinosaurs that need to be put out to pasture.  Talented people like exposure to all kinds of technologies and feel like any technology can be the correct fit given it meets the requirements.  If someone wants to run their data center off of a bunch of Blackberry phones chained together, if it meets the business requirements and can be supported properly, what is the problem?  Ultimately, you are looking for someone who feels that they can provide the most cost effective solutions that are in line with business requirements.

Self-confidence vs. Hubris

Often times there is a thin line between self-confidence and hubris. Self-confidence is the thing that gives one the ability to take on challenges and new technologies.  It’s the positive part that fuels #1 through #6.  However, hubris is the biological weapon of mass destruction that will eventually destroy everything it comes in contact with.    It manifests itself in numerous ways. I’ve seen it come out in “smart people” who called the less knowledgeable or people with less memory capacity, STUPID!  I have also seen it people who think they are above doing certain types of work because of their title.  I have also seen it appear wearing the disguise of “efficiency” .  It sounds harmless as, why can’t someone else do this, I’m paid $100 per second and wouldn’t it be more efficient for someone else who is paid less to do that instead of me? I’m not knocking efficiency, but come on, what company thinks it is normal to break down every insignificant task down to who is the cheapest person to the job.  I’m sorry, if they want me to take out the trash, I agree that it’s not an efficient use of the company’s money, but that is their call and I’m not above taking out the trash.  Here is both sides of that argument, the company pays for my time and I should be willing to do whatever the job requires(as long as it’s legal and moral) but I also have the choice to continue to work there as well if I don’t feel challenged or like what I’m being asked to do.

The Star Trek test

This one is mostly for a bit of humor, but I have noticed some correlation between how ”geeky” a person is by discovering how much they were into Star Trek (original series, spin-offs, and movies) and or other Scifi shows,  Dr. Who, Battle-star Galactica, etc.  I’m curious if others have seen this too.

 

This is only part one, I have so many different topics to discuss. I was afraid that if I added too many more characters that this post would require a warning statement about reading it why operating heavy machinery.  As all ways, if you have feedback or comments, either comment below or email me:  feedback at itminddesign dot com.   If you found it useful or entertaining please share it.

Last Stop - Grand Central!

Grand Central - located at http://www.flickr.com/photos/etobicokesouth/550463229/sizes/l/ by *Muhammad*'s

A few days ago I signed up for a beta for grand central.com. I had seen this site mentioned on a few blogs including Blogger Buzz and BlogNewChannel. I’m not sure how it works, but I know I like it.  It’s a neat concept of having one phone number that takes your incoming calls and rings all the phones that you specify at the same time. It screens calls and allows you to block people and numbers. It is pretty customizable with grouping callers into different categories have each category going to a different phone.  You can even make custom voice mail messages for each contact.  There is a bunch of other customizations and some I haven’t tried yet.  It seems like a nice concept though one downside seems you can’t get phone numbers in every area that one might want.  At the main site you can sign up and wait to be invited or I found this link on the blogs mentioned above that was suppose to be for bloggers but it works for anyone who wants to sign up.  Apparently, Goggle had purchased them some time ago which is not something I knew Goggle had done.  I’m not out advertising for Grand Central but I thought was a neat concept and one I had actually tried.

Your Fired - Legal issues with employers and blogging

GavelAs I was scanning through my RSS feeds the other day, I ran into this blog post from this poor guy who got canned from CNN.  I’m sorry he lost his job.  Apparently, CNN has rules about any writing done for a “non-CNN outlet” must be run through the network’s standards and practices department. I’m sure California is an at-will state so they could fire him for having green eyes.  Unless, green eyes is a protected class of people. He actually had created a blog and wasn’t running his content through CNN.  Oopsies… What started to go through my mind centered around if my company had such policies.  I don’t work for a media company like CNN, so I wouldn’t think my employer would care.  Well, I am checking into any policies the company might have, just to be sure.  At the urging of good friend, I searched for some information on legal issues with employers and their employees blogging.  I found this article at the ibls.com site very informative.  It highlights for areas of trouble for bloggers:

  • Defamation Claims
  • Harassment Claims
  • Economic Damages to Employers
  • Disclosure of Confidential Information

Seems reasonable enough.  Don’t say things that are false and a unprivileged statement of fact that is harmful to someone’s reputation.  Don’t make statements about people at work that can be construed as sexual harassment or create a “hostile” work environment.  People shouldn’t do that stuff at work so they probably shouldn’t do that in a blog either. I don’t think that means you can’t talk about coworkers. I do in my blog and will continue to, but I usually want to discuss issues or situations, not attack someone personally.  Attacking people, what good would that do anyway?  Don’t disclose confidential or proprietary information.  Again, things you shouldn’t do at work, don’t do it in a blog.  It seems relatively simple.  Though nothing legal is ever simple.  I did also find this guide from the folks very useful at the Electronic Frontier Foundation (EFF). 

 Part of one of the statements on the ibls.com page is what really worries me.

 an employer may also be liable for an employee’s defamatory private blog

The article crafts this around some specific circumstances. What I don’t understand is how what I do on my own time opens my employer up to being sued.  They can’t control my actions outside the office.  Maybe one of the three people who may read this posting is a lawyer and as some understanding they can convey. I am all about being educated in these matters. Though these days, just being my employer maybe enough for them to get sued.  Lots of litigious folks out there. 

I understand that the things I do and say while “on the clock” means I represent my employer and they have some liability for what I say and do.  This though thread leads me down a related tangent.  If I am a salaried employee, legally how is my “on the clock” defined.  If I’m shopping at the grocery store on the weekend and “harass” someone and they find out who I work for, can they sue my employer? (I guess can anyone can sue anyone for any reason?) I think I’m looking for legal culpability.  Here is one that seems even more gray to me.  If I’m getting on a plane to fly somewhere on Sunday for a work assignment in another city and I do something “wrong” at the airport or on the airplane, does my employer have any grounds to terminate me? Not that they can’t terminate for those green eyes I mentioned before.  I just wonder what happened to the world when the things you say and do not only gets you in trouble but gets your employer in it too. When did employers who don’t  have anything to do with what you say and do on your own time become liable for you?

 I shall post an update once I find out what (if they have one) the company policy on blogging is.
