Diary of a Network Geek

I love science-fiction.

I don’t think that’s a big secret, either.  What you all may not realize is that I have attempted to write it on more than one occasion.  Usually, I fail miserably, for any of a number of reasons, but I still love to do the research.  I figure, it may eventually get used, so it’s worth doing, right?

Well, in my searches for interesting bits of thought on many, many things science-fiction, I came across Atomic Rockets; or So You Want To Build A Rocket? Wow!  What a site!  This guy has collected all kinds of ideas and research into possible future spacecraft and weapons and, well, just about anything you can think of that relates to the “crunchy” parts of science-fiction!  I mean, he references actual physicists and chemists and engineers who are actually trying to make the future happen on this site.  But, he doesn’t lose the fun that drew most geeks like me to sci-fi.

If you’re a fan, it’s well worth a look.  And, if you’re a BIG fan, make sure to check out the rest of his site, too!

UnMovieFriday

Originally uploaded by Network Geek

By this time of the week, my regular readers know I’ve usually reviewed a movie, but not this week.

This past Friday, instead of seeing a movie, as is my usual habit, I was on a plane coming back from Belle Chasse, Louisiana.
Now, to those of you who haven’t done a lot of business travel, this may sound fun and exciting, but, honestly, it wasn’t. I caught a 7:30AM flight out of Houston Intercontinental to New Orleans, where I was picked up and driven to our local office. There, I did some basic troubleshooting and got the “new guy”, who’s only part time so far, up to speed on a couple of things. Also, we got a problem or two that he’d not dealt with before knocked out pretty fast.
Mainly, though, I was there to make folks feel better and assure them that everything was as it should be. In other words, outside of a couple things I probably could have done on the phone, I was mainly there to take people out to lunch.

The books you see in the attached picture are what was in my bag.
I’m still wrapping up A Moveable Feast by Ernest Hemingway, who is one of my favorite authors of all time. It’s been ages since I read anything by him and, frankly, this book is making me fall in love with language all over again. Hemingway has that effect on me. And, considering how concise he was and how conservatively he used words, I find that deliciously ironic. Still, there’s just something about the way he crafts a good sentence that just makes me want to write.
“Do not worry. You have always written before and you will write now. All you have to do is write one true sentence. Write the truest sentence you know.”

The other books are something else again.
Man’s Search for Meaning by Viktor Frankl is about finding hope in the most hopeless of situations. It’s about finding a purpose in life, no matter how small that purpose my seem to others, and clinging on to it for dear life. It’s the book I was reading when I was diagnosed with cancer and I really need to re-read it and refresh my spiritual memory of the lessons that book brought me.
The Canon Speedlite System Digital Field Guide by Brian McLernon will be, I hope, the guide that gets me going finally with hot shoe flashes, both on and off-camera, for DSLR. I brought that with me Friday in the hopes of being able to get to it and finally start to play with my new camera equipment that my tax refund bought me.
No such luck.
Thankfully, I still had Hemingway to keep me company.

So, movie reviews again next week, but the week after, I’ll have been at a wedding on Friday, so I’ll probably miss my regular review then, too, unless I hit a matinee.
Who knows? Anything’s possible!

No, I’m not going to write an article about the guy who saved his own life in Haiti with an iPhone app.

Because, frankly, everyone’s been talking about that already.
No, in this case, what I’m about to ramble about is the news that Amazon is opening the Kindle for developers.  Now, this might not sound like a big deal, but I think it is.  Here’s why…

First, this is a low-power, always-connected computer.  Oh, don’t kid yourself into thinking this is just a “reader”.  What’s under the hood is basically a small computer.   Now, I’m not sure what the operating system is, but I know, for instance, that the Nook is rumored to be based on Android.  Regardless, it’s a basic tablet that can connect to the web.  That, frankly, opens up some real possibilities.
I can see, as an example, a tech like me carrying around a virtual “stack” of manuals in ebook form, while still being able to use the device to troubleshoot problems, like pinging IP interfaces or hitting the web to Google for answers to problems.
But, compare it to, say, the iPhone which has a Kindle app.  And, a Barnes and Noble Reader app.  And, frankly, as my friends are probably tired of hearing me say, an app for everything.  It’s like carrying magic around in your pocket!  (Which does, in fact, sound a little dirty when you say it out loud.)  So, they sort of have to do this, just to keep up.

Secondly, this will definitely up the ante for everyone else’s device.  There were a lot of new ebook readers out at CES this year and I’ve heard a lot of buzz over the past year about how “everyone” is coming out with a new reader.  Again, I reference the Nook, but also the Sony entry and others.  So, now, people will be thinking about all the ways that a tablet will be more useful.
Now, don’t get me wrong, ereaders are great and all, but, honestly, I think there’s more of a market for an easy-to-use device that can do a whole lot more than just display books.  Again, I reference my own experience with the iPhone.  Sure, having a phone that can get your e-mail and handle your schedule is great, but a real smart phone is an animal of an entirely different stripe.  My iPhone enables me to do a whole range of things from check for movie times to checking the weather to checking my checking account to handling my schedule and calendar to, yes, remote access to my servers.  And, it has the ability to read ebooks.  Now, why would I want a single-purpose reader?

And, finally, the biggest, best reason this is important is because Apple has announced their new tablet device, the iPad.  Of course, the iPad is a whole lot more than a simple ebook reader, and not just because it has an after-market for accessories already, either.  So, now, with two app stores for two devices, we will hopefully have competition which will drive improvement in all these devices and give us, the consumer, the best device possible.  At least, in theory.

Personally, after my experience with the iPhone, I’m hoping that the iPad adds some more service and drops in price significantly over the next couple years.  Then, I’ll probably skip the Kindle all together and get an iPad, generation 3.  (Yeah, I’ll probably skip generation 2, as well, due to pricing and budgets.)
Personally, I look forward to our new Apple overlords!  (Not really, but they do design some great products!)

Okay, so this may not be of interest to many of my readers.

But, for the two or three people who do find it interesting…
Have you ever wanted to test some PHP code in your blog’s theme? Well, Jon Dyer has posted a tutorial on how to do that over at his blog, Dyers.org. It’s a cool idea for testing something on your site or blog to see what it would look like with your particular settings and style. I’d thought about how to do this, too, but the way Dyer does it is pretty clever.

Go check it out!

So, if you’re like me, last week when you were thinking about setting a couple New Year’s Resolutions, you were thinking about money.

No, seriously!  Ok, granted, I was thinking about money that I don’t have, but, still, money seems to be on everyone’s minds these days.  Between the economy, which has tanked, and Christmas, which most of us will be paying off for a couple months yet, a little extra cash would be welcome, wouldn’t it?  Well, a great step would be to cut things out of your budget that you don’t really need.  Of course, that would mean having a budget, wouldn’t it?

Fear not!  The Consumerist has just the tool for you!  Yes, now you, too, can download the Consumerist’s Free Easy Excel Budget Spreadsheet and make your very own, personal budget!
Of course, the real trick is [amazon_link id=”0553382020″ target=”_blank” ]sticking to that budget[/amazon_link] once you make it.
Well, at least it’s a start!

No, not a movie review, but a book review.

So, I’ve been reading more lately, which is great.  And, I’ve been doing my best to read fiction and non-fiction.
Sadly, I haven’t been quite able to review it all, thanks to a brutal personal schedule that often has me out late several days in a row, just to try and squeeze in all the work and personal things to make me feel less alone.  So, while I intended to review this over the weekend, I’m just getting to it now.

In any case, I got The Dip by Seth Godin some time ago and read it just recently.  I got it because I wanted to read a book by the famous Seth Godin and, frankly, this one was the shortest.  No, seriously, I wanted to get one of his books, because I’d read about him, but I didn’t want a huge investment in either money or time.  This book fit the bill.
But, also, it turned out to be good timing for me.  In a way, The Dip is an inspirational book, a book about the power of positive thinking.  It’s certainly a motivational book and would fall under the broad category of “self-help books”, in my opinion.

The premise is simple, really.  Godin says that effort in any worth endeavor, espcially those in the business world, has a curve.  Sort of like a learning curve, but it goes deeper than that.  The curve, which he calls the Dip, is what separates those who are successful and those who aren’t.
When we start something new, whether it’s a new business or a new hobby, we throw a bit of effort into it and we see some small results.  At first, a very little effort produces significant improvements and results.  But, eventually every endeavor hits a point where added efforts produce fewer or no apparent changes in skill or improvement of any kind.  This is the Dip.  Many people quit here and don’t push through the Dip to get to the rest of the curve where additional efforts produce increasing results and result in mastery, eventually getting to a very high-level of performance.  The problem is, we start many, many things and can’t possibly pursue them all through the Dip and on to mastery.  Also, we don’t always have the skill, resources or simple ability to follow through sometimes, but we chase after these things anyway, thus wasting precious time and effort on things that won’t pan out, leaving us not enough time and resources to pour into the few things we might truly follow through the Dip into mastery.

On the one hand, it’s inspirational to realize that if I manage to stay faithful to the things I really find enjoyable and worth pursueing to their end, I might make it through that inevitable slump that everyone always hits.  If I can maintain my enthusiasm when things seem to be all working against me or keeping me from moving from dabbling hobbiest to skilled practitioner.  For instance, it gives me hope that my photography will hit that level where I suddenly start getting it and start seeing better and better photographs.  Sometimes, I feel like I’m on the cusp of that already.  An example of how the Dip works, for instance, is the 365 Days project on Flickr.  The goal is to take a self-portrait every day for one year.  Most people hit a creativity wall at three months or less.  Many bail out at that point, and, in fact, I almost did myself.  But some carry on through the slump, fighting the urge to just throw in the towel, waiting for the creativity to spark again.  Even then, some of us never get that creative spark back and our photographs never improve or we drop out later, midway into the Dip itself.  Quitting in the middle of the Dip, incidentally, is something Godin warns about.  Better to quit sooner, and not waste the resources to get further along only to quite later.  Or, better still, to perservere and make it through the Dip to the other side, thus achieving a new level of skill and competence.  I haven’t given up on my 365 Days Project yet, so I’m hoping I’m not the only one who’s seen improvements in my photographs.
And, The Dip also helped me realize that I need to waste less time on things that I know I won’t follow through on and drain my resources, thusly preventing me from pouring more effort into the things I really want to do well.  Now, I’m having to look at what I’m going to “quit” to make room for more effort for my photography and my writing.  I’m a little afraid that it will be sleep I give up to make room!  But, no matter, this book pointed out some deficiencies in how and where I spend my effort.
That needs to change.

I have to admit, I was skeptical about the hype associated with Seth Godin.  I mean, how good and brilliant can one man be, especially when it comes to sounding off about business and management?  But, this book really helped me see some of what’s been going wrong in my life much more clearly.
It’s already motivated me to workout more and more regularly, in an effort to improve my over-all health and appearance.  And, it’s provided considerable encouragement to keep working at my photography.  So, for those two things alone, it was worth getting.
I recommend The Dip for anyone who feels “stuck” or frustrated that they’re not moving ahead in their personal projects.  I’m sure it’s great for business, too, but I got plenty out of it for myself.
I think you will, too.  Trust me, it really is worth the read.

Good old science-fiction.

Hey, want to hear something cool?  Head over to Escape Pod and listen to Charlie Stross’ latest story, Rogue Farm.  But, first, stop by Biology in Science Fiction for the link, so they know we care and appreciate them bringing these kinds of stories to us.

I may post again later today, since I was at a wedding last night and very good friends of mine may be having their baby today, but for now, this is all I’ve got.

HalfBloodPrince

Originally uploaded by Network Geek

I saw Harry Potter and the Half Blood Prince Friday night.

It wasn’t bad. It wasn’t great, in my opinion, but it wasn’t bad.
Now, I read the entire series several years ago now. In fact, I finished the last one while I was in the hospital getting chemotherapy. But, it’s been so long since I read the books that I don’t remember all the fine details. I did, however, see the movie with a friend who does remember that kind of thing and he said that the movie was very true to the book. The one deviation is that the funeral at the end of the book is not in the movie.

Now, here there be spoilers, so if you don’t know the story, skip to the last paragraph now.
So, okay, most of what I remember from the book was there, for sure. A little different and compressed, of course, but mostly still there. I have to admit, I skipped a couple of these movies, in part because I was going through a divorce and cheating death when at least one or two of them came out. But, also, I just wasn’t that into the movies. I couldn’t stop reading the books when I started them because I had to know what happened next, but not so much with the movies.

All that being said, I remember more mushy romance, more dark, dark, dark stuff with Tom Riddle/Voldemort as a boy. He was pretty nasty and they just hint at what ways he may have been a mean, cruel young man and why in the movie. Also, I seem to recall more mystery and intrigue with the Draco Malfoy sub-plot and the whole thing with Severus Snape. By the time we got to the famous Dumbldore murder scene in the book, you’re not sure what side Snape is on and convinced that Harry must die to defeat Voldemort. But, I wasn’t sold by the end of the movie. Granted, I know how things turn out, but, frankly, Rickman’s heart just didn’t seem to be in Snape this time out. I think he may be getting tired of this role, but I’m sure he’s getting paid quite well to do it, so, whatever.

There was one scene that stood out for me which was just how I remembered it from the book, though. When Dumbledore and Harry go to get the horcrux in the cavern on the storm-wracked coast, it was pretty well as I remembered it. Or, perhaps, even better. Pulling up the boat from the hidden lake via the chain, and the corpses beneath it are both just how I pictured them. Especially those angry, swampy corpses trying to drag Harry down to join them.

Other parts, though, just seemed a little glossed over, which, I suppose, is why they’re breaking the last book into two movies. Also, bigger profits.
The one thing that they left out, which surprised me, was the very formal funeral of Dumbledore. I suppose it would have taken too much time and, besides, they got the point across with the scene that did end the film.

All in all, though, in spite of some variation from the book, this was a very good movie. I don’t think it was a great movie, like the first one, but it was well worth seeing. Also, it was one of the better films of the season, for sure. If you’re a fan of the books, or just a fan of the earlier movies, this is a must-see movie. If you haven’t, somehow, seen the other movies at least, go rent them, then see this movie, or you’ll be totally lost.
So, final verdict, good and worth seeing, but not great.

It seems like this comes around on a regular basis.

Server names and naming conventions are a constant source of argument and irritation in big IT departments.  Everyone has their own idea of just what naming schema should be used for the servers and workstations and such on the network.  And, since it hasn’t shown up recently on Slashdot, we were about due for an article on it.  There is; Why do we name servers the way we do?  The comments, if you can be bothered to dig down deep into them and wade past some of the worst attempts at humor, are quite telling.  It doesn’t take long before the relative merits of using quirky, easy to remember names is being quite hotly debated.

The original article  over at IT World, titled Would a server by any other name be as functional?, seems to weigh in on the side of the more creative names.
I’ve worked both kinds of places, actually.  In one job, we used a very precise naming convention that had been put in place after some, apparently, very intense debate.  There, we used the LocationFunctionOperatingSystemNumber kind of naming system.  So that the first Accounting server in Houston running Novell Netware would be HOUACTNW01.  Perfectly clear to me, actually, because of that job.  It’s a logical system and works well enough, though it does lack a certain “zing”.
At most other jobs, though, we tended toward the other way.  Once, I worked with a guy who named his servers after dead musicians and actors, but that was only so he could ping his favorite router and see “Hendrix is alive” come back to him.  Another place, we used various things and it was, well, far less themed and much more confusing.  I think it’s best to choose from a very, very large mythology or naming pool so that you don’t have to switch themes mid-stream.  We had some servers named for “gods of the underworld” and others that were named after space shuttles at the same company.  There was no rhyme or reason to it, really, just what the last guy felt like doing.

I’m not sure what naming convention I’ll finally use when I finally get around to redoing my network at home.  It’s hard to get motivated, you know?  When you do it at work all day?  Makes you feel sorry for sex workers and gynaecologists, not to mention urologists, doesn’t it?
(Yeah, this is what happens when I stay up way too late.  Or is it too early?)

Well, okay, maybe not non-geeks, but non-network-geeks, at least.

As many of you well know, I am almost always pressed for time. That’s partly due to my work, which seems to include more and more front-line support and less and less networking coolness. It’s just the way things go. In any case, …

So, don’t be intimidated by this. You can diagnose most of your own network problems. Just head on over to the Linux Journal’s website, where Mike Diehl has written a pretty comprehensive article on Troubleshooting Network Problems. Oh, and don’t let the fact that it’s on a Linux website throw you, he has tips for Windows users, too.
