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“.

10 Things: Securing Wireless Connections

This sort of seems like an oxymoron to me.
But, I suppose in this modern world of ubiquitous, wireless connectivity, we must hold tight to our illusions of security. Toward that end, TechRepublic has an article titled Ten Things You Should Know About Securing Your Wireless Connection. I still can’t, in all good conscience, reccomend that you run anything you want to keep secure over a wireless connection, but, if you must, at least read this very short article about keeping your connection as secure as possible. Certainly, if you’re doing this at home, it’s worth the look. If you’re attempting to keep a secure wireless connection at the office, and haven’t started hitting the “happy sauce” yet, this is a good place to start, though I sure wouldn’t run any important financial data over wireless, either at home or work.
Well, it’s a good article, even if I have my personal, Luddite misgivings about wireless.

Digital Ink a Reality?

Is such a thing possible?

Well, according to this article on Yahoo, it just might be! Imagine what it might mean to the future of publishing. Add in some wireless connectivity and you’ve really got something here. Textbooks that change based on which class a student is in when they’re opened. An entire university library available to students on campus, wirelessly. Books that can be downloaded from the ‘net directly to a reading device.
Then, of course, there is the interactivity aspect. The article talks about catalogs that can be used to place electronic orders. Add in the ability to automatically update inventory, price and availability and you’ve really got something.
Of course, we’re a ways off from that, so it’s still science-fiction, but the possibilities are endless. In a fully networked world, devices like this might replace PCs alltogether. They would become the ultimate PDA. It could be the Next Big Thing. We’re always looking for that Next Big Thing to invest in or adopt. The concept of “digital ink” has been around for some time, but it looks like they’re finally getting somewhere with it. It sure will be interesting to see if they finally pull it off!
