Mashups Strategies for the Modern Enterprise Review

I went to the local library to pick up some books, this time I actually browsed the IT section. To my surprise I found some relatively (in library sense) new books, one of which was “Mashups: Strategies for the Modern Enterprise.” I wasn’t going to pick it up, but I saw it was from Addison-Wesley. Not only my favorite publisher because they publish decent books, but they also have a great logo (triforce anyone?) If that wasn’t enough to convince me, the cover certainly was. I mean come on its a pear-orange-lemon-plum-lime-apple I’d like to see what one of those tastes like. Essentially this is what this book is about; Mashups. Taking things that don’t necessarily belong together and bringing (mashing) them together to make something new and interesting.

I thought I knew a bit about mashups, which is why I was hesitant to pick it up. After taking it home I found it to be way more in depth than I first imagined. Explaining different models in depth really makes one think about the larger pictures. There is a whole chapter dedicated on how to create a sample mashup. It gives the principles and leaves the reader (in this sense me) with a better understanding of the inner workings of mashups. It even includes a portion on security that doesn’t just seem like it was added in as an after thought.

I may just have to pick up my own copy of this book because I feel bad that I’ve renewed it once already. I think other people could benefit from reading it. Who knows maybe they’ll read this review and use the recall function, its definitely worth the time and money.

Perform an action when a host comes back

Filed under: Shell Script Sundays — TheLinuxBlog.com at 6:28 am on Sunday, October 24, 2010

Perform an action when host comes backI have in the past been lazy enough to not wait for a host to come back, yet need to do something when it comes back. Lets say starting up that service I never got around to creating startup scripts for, or uploading new firmware. Well, I found this little trick on NSLU2-linux.org

sudo arping -f  && echo "True"

Obviously the echo “True” can be replaced with whatever you wish. A sleep may be good if you want some extra time before performing the action. Pair this with a SSH identity / key pair and you can perform the actions on the host remotely.

In the blue corner we have reigning champion FreeMind and in the red corner we have a new contender for the best mind mapping software kkkkkkkkkkkdissert.

GLTron

With the upcoming release of Tron Legacy I can’t help but play this game. Now if only a 3D version got released and a certain some one would stand inline to get me 3D television on Black Friday. Better yet, code the 3D version WHILE waiting in line for Black Friday sale. Odds are I’ll probably get a leaf blower, ladder or something with lesser or equal buzz killing potential.

Check out my GLTron skills. Make sure to watch it in 480p and take no notice of the number of “Player 1” crashes in the top left hand corner, that obviously wasn’t me. There also is NO sound, but you can install it, play the soundtrack at the same time and get the same effect. I think the only time I’ve ever been more 1337 was when I hacked that Gibson, but that’s a-whole-nother story. Also take note of the length of this video, a total accident.

Shell Script Sundays

I’ve been trying to keep up this blog for a number of years now. Problem is, I think I over committed when I created the Shell Script Sundays column. I’ve been keeping it going as best as possible, and will continue to do so, but I’m not going to be able to do it every week. If you may have noticed, I haven’t done any on a regular basis anyway. I do however, have some queued up for every other week, but I don’t know how long I’ll be able to continue doing that. There is also, only so much you can write about shell scripts. If anyone wants to step up and write some shell scripting articles you’re more than welcome to do so.

This will be my 70th article written since I’ve started. I doubt any one will even notice anyway, if you’d like to see it make a comeback, let me know.

That is all.

Making Environment Variables Stick

Filed under: General Linux — TheLinuxBlog.com at 5:00 am on Sunday, October 3, 2010

So, setting environment variables is a pretty easy task right? I thought so too but recently I was unable to read a variable I set from within a Tomcat application no matter what I tried. The problem turns out was easy to fix.

All I needed was to set an environment variable, I didn’t care who had access to it since it was just a path but whatever I did, it just wouldn’t stick. I quickly found out from a co-worker about a magical command that would have been a solution. Problem now was he couldn’t remember what it was. Well it turns out that it is a bash built in called source. Using this with the /etc/profile file as follows: “source /etc/profile” fixed the problem without a reboot.
