Diary of a Network Geek

Yeah, you read that right.

It’s no secret that I love my digital camera.  Not quite enough to give it a name, like some photographers I know, but, still, I love the little fist-full of magic that lets me take amazingly detailed digital photographs.  I remember when my ex-wife got her digital camera, it was a big deal that it was something like 3-megapixels.  Now, my iPhone has a camera at least as good as that built into it!  The camera I use now is a 10 megapixel camera and that’s really just an entry-level DSLR, which is 3 years old.  The better cameras start at 20 megapixels and go up from there these days.  That, let me assure you, is capturing a lot of data.  We’ve come a long way in a short time.

But, researchers are working on cameras that make those look primitive.
According to Scientific American, DARPA researchers are experimenting with gigapixel cameras.  That’s over a billion pixels.  That’s like 333 times better resolution than an iPhone camera.  That, in short, is pretty amazing.  And, not only does the camera take amazing shots, but it looks amazing, too.  Check out the slideshow at Scientific American that shows the camera and a picture it’s taken.

There’s something to think about as you snap photos of your friends this weekend!

So, I promised you more technical stuff here, right?

Well, stop yer grinin’ and grab yer linen, ’cause here come a fist full of links with some great advice for network administrators, all from TechRepublic:
First, if you’re a real network admin, you’ve dealt with traffic issues on file servers.  Issues that have hidden sources.  Unknown processes that jam up your network connections until your users scream for your head.  So, how do you deal with that when you’re on a budget and don’t have a lot of tools?  Well, one way is to use “netstat” to look at what process is running on what port and sending what volume of data.  If you’re on Unix, you probably already know about this tool, but if you’re on Windows, check out “Netstat tips and tricks for Windows admins“.  It may save your bacon one day.

Second, you probably have wireless in your network now, too, right?  But, it may not always work quite the way you want.  Once again, users will scream bloody murder if they can’t read their blogs on their iPhone, so, how do you find out what’s jamming up your WIFI network so that no one can connect?  Read through “Troubleshooting for wireless connectivity issues” to get you started on running down the problem.

Thirdly, if you’re a REAL network administrator, you probably have at least one Linux box in your network.  Something that runs an open source network inventory or monitoring tool or, maybe even, an actual Linux file server.  In any case, sooner or later, even that sad, little, neglected Linux box will have disk space issues, so here are “10 things you can do when the drive on your Linux box is full“.

And, finally, my personal favorite.  You hear a lot of buzzwords floating around these days in IT shops, but “the cloud” is the most common magic cure for all ills.  Personally, I’m not so sure.  I worry about things like, oh, you know, security and auditing and connectivity issues and little details like that which seem like they might be an issue for the magic cloud computing panacea.  Turns out, I’m not the only one.  So, go see why Patrick Gray says “The cloud doesn’t matter“.

Lifehacker loves iPhone apps almost as much as I do!

No, seriously, I use this thing for everything.  Not too long ago, I showed you a ToDo app that makes life easier for you when trying to keep track of all the things you need to do.  I’ve talked about other apps before, and, of course, earlier this week, I mentioned that people are using their iPhone as a security testing tool.  Really, there’s no end to what you can do with today’s smart phones, though I happen to prefer the iPhone, obviously.

In any case, Lifehacker has put together a list of apps that they recommend, most of which are free.  And, the few that aren’t are only a couple of dollars a piece.  If  you’re a heavy iPhone user, it’s worth it to go take a look at their selection of “must have” iPhone apps: Lifehacker Pack for iPhone.

No, this is not a post about sexual performance.
Pervs.

I use my iPhone for a surprising variety of things, even at the office.  For around $14, I threw together a suite of network scanning and testing tools that let me get a pretty good look at any network I manage.  But, that’s another post.
Today, I thought I’d bring to your attention a great blog post by Nicholas M. Petty tittled “iPen: Hacking with the iDevice“.  What he’s got is a set of instructions and tools for turning your iPhone, or, presumably, your iPad, into hand-held computer security penetration testing tool.  Yeah, I know, it still sounds dirty when you say “penetration”.  Grow up.

If you’re into security, whether you own an iPhone or not, it’s worth going to take a look at just to see the thought process and methodology.
Now, as much as I love this idea, I probably won’t actually do it myself because the first step is to “jailbreak” your phone and, frankly, as tight as money is and as important as my phone is to me, I can’t afford to have problems with it.  Still, it is an interesting idea, especially considering how many of these little devices are wandering loose out there and how many wifi access point exist out in the world.  I often wonder how secure any of them really are, especially in corporate environments.

Anyway, this should be something for network managers to think about the next time they see someone in the lobby of their building “playing a game” on their iPhone!

It’s no secret that I love WordPress.

I mean, seriously, I really, really love WordPress as a blogging platform and as an easy-to-understand Content Management System.  But, did you know that I’m one of the three most important people in WordPress? No, for real! And, I have a certificate from Matt Mullenweg himself to prove it!

Okay, so, yeah, I know, I’m not really one of the most important people in WordPress, outside of being one of millions of users who do, in fact, make WordPress a force to be reckoned with. But, we only manage that as a group, as a community. No, that certificate is a joke. Literally. It’s a joke from Matt Mullenweg, founding developer of WordPress, regarding an incident some weeks back involving a theme developer who didn’t want to use the GPL, which is the software license that WordPress uses and all theme developers are required to use. I know people will disagree, but, based on my understanding of the GPL, any derivative works of a product that uses the GPL must also use the GPL.  So, really, for most of their code, theme developers are required to use the GPL.  Honestly, I’ve never worried about it.  I mean, mostly, it’s a bunch of legal speak that means very little to the average end-user.
One of the things that this theme developer claimed, erroneously, was that he was one of the “three most important people in WordPress” because he felt that so many people used his theme.  I think he may have been surprised at how many of those folks jumped ship when they found out there was something wrong with that theme and its license.

In any case, what does matter to us about all this is that Matt took that attention and made a marketing opportunity out of it.  For starters, he started buying people premium themes that didn’t violate the GPL as a kind of protest and a way to draw attention to how serious he is about supporting the GPL.  And lots of people took him up on the offer.  But, apparently, someone griped about not wanting a premium theme or something and so, instead, Matt made a second offer to those of us who didn’t want, or couldn’t decide on, a premium theme.  He offered us free t-shirts.

Well, I’m always up for a free t-shirt, especially one that advertises something I believe in and use, so I was on this offer like white on rice.  Now, I can only imagine how many people also took advantage of this, too, but I went to his website, and filled out the form and sent off my e-mail like a kid sending in his box-tops for his toy surprise.  And, then I forgot about it.  I try to do that, frankly, when I enter contests and such.  Like casting my bread upon the water, I do what I need to do to enter and then forget it.  That way, if something does arrive, I’m pleasantly surprised.  That’s just what I was this past Friday when I found the package from Matt in my mailbox; pleasantly surprised!

As you can see from the picture, the t-shirt came with a few other things.
First of all, there were all kinds of stickers, which I love.  It reminds me of the old days when you got swag at the conventions and covered your laptop in stickers.  But, there was also an iPhone skin and pencils and, of course, the certificate, which made me laugh out loud.
I’ve already worn the t-shirt, which, as you can see, says “Code is poetry” on the front.  What you can’t tell from the photograph is that the t-shirt reads “WordPress.org” and has the official WordPress logo on the back.  Frankly, that’s the part I love.

Now, all I need to do is actually read all those books I’ve gotten on WordPress theme design and get working on it…
Anyway, thanks for all the stuff, Matt!

Okay, I know the iPhone is amazing, but this really is cool!

So, when I was on the road a lot, I would occasionally have to do presentations.  That usually meant lugging a laptop which I could hook up to a projector, if they had one available.  Often, it meant added pounds for a day trip just to show a team a few screen captures or a short slideshow.  Not good.
Well, now, if you’ve got an iPhone, you can carry a tiny projector with you instead and reduce your overhead without losing any production value.

Okay, it’s not quite available yet, but it will be soon.  Personally, I can’t wait to see how much it runs!  And, with everyone talking about the new iPad that isn’t quite available yet either, I thought it’d be okay to talk about a vapor-ware add-on for an existing product.

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!)

Yeah, so now I’m reviewing iPhone apps.

One aspect of my personal life that probably doesn’t come through that much on this blog is how concerned I am about health and, specifically, my weight. Now, some of this may come from having been married to a self-diagnosed anorexic, but, mostly, it goes further back than that.  In any case, weight and general health have always been a concern for me, but even more so since surviving cancer.  So, I know from all the health magazines I read that one of the greatest tools for weight loss is tracking caloric intake.  I had been doing this via a Moleskine, but I always had to look up the calories in a book or on a website or something.  It was just challenging enough to make me want to quit.  So, naturally, when I got an iPhone, I went looking for an app that let me do record my intake that way.  Enter FoodScanner.

Not only does this fantastic app have seemingly endless lists of food, including many popular restaurant menus, but you can scan the barcode on the package and it will automagically find the food and all the nutrition information for it.  But, wait!  If that’s not in the database yet, you can add it in manually and link the barcode yourself!  How cool is that!  Seriously, I love this thing.  It’s made it so much easier to track my calories I can’t believe I ever lived without it.  And, at $0.99 it’s a real bargain, especially if you want to work on consuming less to lose weight.  Fantastic!

Originally uploaded by Network Geek

Now, as cool as FoodScanner is, what’s even cooler is the free app that goes with it called DailyBurn.  To get the full functionality, it does require that you setup a free account with their service, but, trust me, it’s totally worth it.  Once you’ve setup your free account, DailyBurn will get the calorie and nutrition information you put in with FoodScanner and use that, so you don’t have to enter it twice.

Now, as you’ll notice from the screen shot to the right, the default screen on DailyBurn shows you your caloric intake, what you’ve burned via work outs, and your current and goal weight.  There’s also a tracker to show if you’ve met your workout and nutritional goals, which I’ll mention later.  This page, as you might have guessed from the title “Today’s Stats”, is updated daily, which they define as 12:00AM to 12:00AM.

Notice, though, that the Nutrition indicator only shows when you’ve met all your “goals”, which, frankly, aren’t quite my actual goals.  For one thing, I want to keep my calorie consumption below what they have as a goal, so as to lose weight.  Also, notice the “Upgrade to Pro” link.  That takes you to a sign-up screen for a monthly membership, which I didn’t want to get roped into paying.  Not sure what the upgrades are, actually, but one presumes additional control over goals and additional exercises and other options.

Originally uploaded by Network Geek

On the screenshot to the left, of this paragraph, you can see the “Body Tracker” page.  Here you can track any number of physical characteristics including weight, waist size, body fat, resting heart rate, arm size and many more.  Frankly, it’s got all the recording features of any big program that you could want.  Also, if you upgrade your free account, which I have not done, to a “Pro” account, there are even more things you can track, like sleep levels.

I like having the chart to see how well, or poorly, I’ve been doing over time.  Sure, maybe it’s a little bit over-kill, but, I’ll be honest, I love charts and graphs and stats.  My favorite page on my Flickr account is the stats page.  It’s true; I’m a stat whore.  So, yes, this feature appeals to me.  Your mileage may vary.

Also, like I mentioned, I didn’t want to get started paying a monthly fee for something I may not continue to use in the long-term, so there may be additional features here that are worth having.  Not sure.   Right now, I’m just a rookie fitness nut, so my health isn’t worth a monthly fee for those kind of intangibles.  Heck, I don’t even pay for a gym membership yet!  So, that may be something worth checking out for you super-hyper fitness nuts.

The next page I seem to hit a lot is the “Workouts” page. Granted, I’ve probably worked out more since I got this app than I have in the past month, but, still, if it’s working, then that’s all that matters.

Now, one of the things I don’t like is that the exercises it DailyBurn measures are somewhat limited.  And, you can’t enter anything new.  So, if, for instance, you were to get exercises out of Men’s Health and knew the caloric expenditure, there’s no way to enter that in.  Now, I assume that buying the “pro” version of this, which is actually a membership and not a one-time payment, you might be able to add more exercises or have a larger selection, but, frankly, I get close enough that it’s not worth it to me to pay a monthly fee for that kind of “upgrade”.

I should also note, however, that I haven’t looked into the “My Workouts” section too much, but it looked like it had promise.  It gave you workouts to achieve certain goals, like Fat Loss and Strength Building and so on.  Under each section, there are several workouts designed to help you with that particular goal.  Kind of like a personal trainer in an iPhone app.  (Though, I prefer the Men’s Health app for those kind of things to the ones I saw in DailyBurn.)  The last section is essentially a workout log that shows all the sets you’ve done and how much weight you lifted on each set.  The only problem is, it only shows today’s workout, not any previous day.  It like this to show a chart of progress, not unlike the body goals charts shown above.  But, again, I’m sort of a stat whore, so take that for what you will.

Originally uploaded by Network Geek

Now, what I think is the best thing about DailyBurn, next to showing me how little I burn off with my wimpy home workout, is the “Nutrition” screen.  I specifically chose the screen at the left because it showed several things I want to highlight.  This is not what I hope a “typical” day is for me.  Or, at least, not what I hope a typical day will be for me going forward.

In any case, you can see that it shows you your consumption levels and whether or not you’ve met your “goals” for the day.  Goals not met are shown in blue.  Goals that are in the “good” range, or met, but not exceeded are in green.  And, finally, goals that have been exceeded are in red.  You can see that I was a bad, bad boy on the day used as an example.  Also, since I’m trying to lose weight, I’m doing my best to keep my caloric intake between 1500 and 1900 calories.  My goal here is to burn more calories than I actually need so as to shed some poundage.

Now, again, I’m a total stat geek when it comes to this stuff, so I love see all this.  Also, in just the few weeks that I’ve been using these two programs, I’ve learned some very valuable lessons.  For one thing, I need to work out more.  My little, tiny workout in the morning doesn’t even burn off breakfast most days!  Not acceptable!  So, I need to adjust that.  Also, I noticed that I’m not getting anywhere near enough protein while consuming way too many carbs and, obviously, more than enough fat, too.  So, I need to adjust my diet as well as step up my exercise program.  But, it took getting good information to do it.

For the couple of bucks it cost me to get FoodScanner and the free version of DailyBurn, I’ve gotten a lot of valuable information and awareness of what I need to change and improve in my personal health and nutrition plan.  Well worth the small change I paid.

I saw a bunch of movies in the past two weeks.

I know I see a lot of movies, but, until I got behind on my reviews, I didn’t realize just how many!
So, these will be three short, quick reviews to help me catch up, also they’re being written on the WordPress iPhone app, which encourages brevity. I’ll review them in the order I saw them.

First up is Extract, which is a Mike Judge film. He’s the guy who did Office Space and if you liked that you’ll like this one, too. This time, the “hardluck hero” isn’t a front-line worker, but management. In fact, he’s the owner of a small factory that creates extracts, like almond extract and other flavorings. Now, this might not seem like a funny setup, but, trust me, it is. Judge manages to find the hilarity in an over-worked, under-sexed small-business owner, trapped in an unhappy marriage and disenchanted with his own creation, played by Jason Bateman. He struggles with all the problems attendant to an entreprenuerial business, but manages well enough. Until, that is, there’s a freak accident in the factory that partially emasculates one of his star employees. That alone wouldn’t be a problem, actually, but it draws the attention of a sexy grifter played by Mila Kunis. She conivces the “victim” to sue, setting off a chain of events that are not only tragic and hilarious, but also so incredibly believable that you never question how outrageous they are or the reactions to them.
Trust me when I tell you this will be a cult hit just like Office Space was. I laughed out loud so often my sides hurt by the end of the movie. Oh, and Gene Simmons as the ambulance-chasing, shyster lawyer is too funny for words! Watch for his ad in the background because when he does it in Spanish you’ll have a hard time controlling you bladder. Very funny film and, if it’s not too late, a must see.

Last week Friday, I saw The Informant, starring Matt Damon. Now, you might not expect that an action star like him could do comedy, but he really pulls it off.
Now, this movie is an entirely different kind of funny than Extract. It’s still funny, but as much in that over-the-top sort of way. It’s a dryer sort of comedy, almost British in where it gets its laughs. I doubt it will do as well as other comedies this season for that reason, but I found it very funny. Also, this movie is based on a book which is in turn based on actual events. In. nutshell, Damon stars as an exec at ADM, a corn conglomerate, who gets into a tight spot and does some lying to get out of it. The only problem is, those lies bring in the FBI who need to be distracted. So, in an effort to save his own skin, he rats out the company on a huge price-fixing scheme and ends up being an FBI under cover informant for almost three years. Of course, during that time he also embezzeled more than 9 million dollars and never seemed to tell anyone the while truth, not even his wife, not even himself.
Damon is clever and likeable, in a kind of nerdy way, as the obviously not quite right Mark Whitmore, who still thinks he can steal from the company, become the next president after the old management team is out, and inform for the government at the same time. The really funny thing is that he manages to pull it off for three years before things really start to unravel. And, this movie is more than just laughs. You see a guy under incredible stress trying to maintain his sanity, world-view and family image while betraying those very same things. Near the end, Damon has some truly poignant moments where the frayed edges of his assorted lives and realities begin to show through. I really liked this film, but I doubt most people would. I honestly don’t see it doing well in the theaters or in rental, but I really enjoyed the surprsing subtlties in this movie. Damon turns in a fantastic performance that I suspect will go largely unnoticed by the public. If you’re a Matt Damon fan, definitely rent this one.

The last film I saw last weekend was Nine. Nine is a pretty adult animation film. The story follows Nine, a magically created living puppet in a post-apocalyptic world. He wakes not knowing who he is or why he was made and not even having a voice. Nine quickly explores his world, however, and meets more of his kind, one of whom helps him find a voice, literally. When that other “person” is taken by some malevolent machine, Nine tries to convice his newly found brethren that they need to go and rescue their missing member. Much of the film is spent in that sort of activity, either convincing older “people” who are afraid of losing thei power to change, or off fighting technology that has no soul.
And, that is one of the major themes of this movie; fighting the soul-less technological world. In a sense, this movie is all about heart, but it’s also an action film of sorts. And it was animated. Actually, it was animated very well, so that’s a point in its favor.
I’d recommend this film for anyone who’s either a sci-fi fan or an animation fan, but it’s not for the kids. Way more grown up than that. But, even though I liked it quite a bit, I don’t think it’s everyone’s cup of tea.

So, to sum up, go see Extract quickly, rent The Informant, and see Nine if you love sci-fi or animation or both, otherwise just rent this one, too. But, for the record, I enjoyed all three films.

Oh, and just so you know, this was meant to be posted yesterday morning and would have been the fifth consecutive post written primarily with the WordPress iPhone app beta. Outside of a problem uploading pictures, the beta app is working very well.
More movies this weekend, so, more reviews coming, though, they may not all be via the iPhone.

I love this app.

No, seriously, this free app highlights all that I truly love about my iPhone. It checks to see where I am then finds movies and theaters near me. It shows me what’s playing, when it’s playing and where. And, if I’m not sure where the theater is, it even links to maps to get me from where I am to the theater of my choice.

Oh, and did I mention the app is free? Yeah, sure, Fandnago would love for you to set up an account with them to buy tickets, but you don’t have to do that for the app to work. How cool is that?

But, wait, as Ron Popiel would say, there’s more!
Because, if you’re not sure what film you want to see, there are ratings from critics and other Fandango users to help you decide. And, if that’s still not enough, there are previews. Yes that’s right, actual previews you can watch on your iPhone!
Now, I’m sure you’re thinking that watching movie previews on a tiny phone screen would be terrible, but, Saturday night after church, at least five people crowded around my iPhone to watch movie previews and were so drawn in not one made a sound while the 9 trailer played. No joke. All adults, too, over the age of 21.

In fact, I love this app so much that I’ve been thinking about getting a Fandango account. Which, of course, is why they offered this app for free, I’m sure.
But, you know what? It’s totally working.
