So, I found a way to download, burn and install Fedora. This normally wouldn’t be a big deal but I’m roaming house to house until Rose and I find somewhere to live. I survived Iraq with Fedora 8 and I really wanted to try out the latest. I really enjoyed 8. It was stable and served me well on my journey.

But, being the geek I am, I couldn’t resist but install the latest and greatest. And, two days later, I have no regrets. I can honestly say that this is the best distribution I have tried. I used Ubuntu 8.10 as soon as I got home to see what had changed on the Debian front. I wasn’t all that impressed. While it operated smooth, it was missing a few bits which I really wanted. It was lacking the latest OpenOffice.org, Mono and Eclipse and it excluded the Empathy IM package which I wanted to try. It also didn’t have a ready-to-go NetBeans installation in its repositories.

There is really nothing much to say about the installation of F10. The installation was smooth and easy. Everything just worked. When it first booted, I noticed an immediate difference. Not only did the boot process look different, it also booted a lot faster than F8. This is due to the inclusion of Plymouth as a replacement for RHGB. I wasn’t sure why it looked so plain though. It was just a black screen with a progress bar across the bottom. After some searching, I found that adding “vga=0×318″ would allow a more graphical boot screen at 1024×768 with 16M colors. After the change and a subsequent reboot, it looked more like one would expect.

I would have to say that the folks working on NetworkManager have done an outstanding job. I didn’t my Kyocera KPC650 Verizon card with me during installation. However, it didn’t matter. I just plugged it in while working from the desktop and NetworkManager detected it and I was able to connect in seconds. This was much smoother than using wvdial or any of the other older methods. It is also considerably better than Windows approach.

After adding all my bits, I found that I didn’t need to reference any documentation to get my system 100%. It just was. Everything was there and working. I did add the RPMFusion repos to yum but this is as simple as clicking on the download on their site. Viola, libdvdcss, gstreamer-ugly, et. al. were all there and ready.

I do have one complaint with Gnome. The default image viewer application is just too simple. It doesn’t offer any photo touch up tools or anything. I really wish the folks at Gnome would begin pushing gThumb as the default. It is fast, lightweight and simple enough to use as the default. Yet, it offers those that want to crop or adjust color the tools necessary to get the job done.

In conclusion, I would recommend F10 to just about anybody. It is as stable as any release I have ever tried. It is also as bleeding edge as they come. Those two rarely come hand in hand. It’s nice to see they got it right with Fedora 10.

A really interesting post was placed on the Royal Pingdom blog that compared average load time and up time of operating system websites. The author took measurements from October 17th through November 17th. He used 16 Linux distributions, Apple.com and Microsoft.com. While his results were interesting, I felt a correlation between page size and load time should be included. I asked the author about this and he responded, “from a user perspective it doesn’t really matter what size the web page is. All that matters is how they experience the load time.”

I created the chart below based off his data and a current size snapshot of the same web pages. I used a Firefox add-on called lori or Line-of-request info to measure the complete size of the page including images and anything stored in cache.

The following two charts show the actual size of each page including scripts, images and html and their speed to load in KBps based on the data from Pingdom.

OS Vendor Website Speed (KBps)

OS Vendor Page Sizes (KB)

Conclusions

• Most popular, well funded operating systems have main pages which, regardless of size, have ample bandwidth
• If all linux sites are combined, the average speed is 130.35KBps. The median speed is 70.84KBps.
• I’m not sure if the Suse Enterprise site load time was measured correctly. It measures in at a whopping 388KB! However, its load time averaged 591ms giving it amazing results. I am wondering if the flash heavy website wasn’t being measured correctly in Pingdom’s tests.
• There seems to be a direct correlation between the funding, bandwidth and bloat of the website. I guess if you have all the bandwidth you could ever want, file size doesn’t matter. Unless you want to be nice to those of us with SLOW INTERNET!
• It is interesting to point out that even those with the slowest transfer speeds will still usually beat out the loading of the bloated pages from a users perspective. This is ultimately what really matters as pointed out by Pingdom.
• PC Linux OS could really do themselves a favor and get rid of some bloat!
• Apple and Ubuntu seem to be the most balanced between size, bandwidth and load times.

So, as most of those who know could have guessed, I’ve become the computer fix-it guy over here. Between our firewalls, proxies and lack of reliable phones, troubleshooting is made difficult. The past week, I have had to fix four computers. That makes nine complete format and OS reinstalls. Of those, all nine had Windows Vista installed. I’m not a Vista guru but it seems to me that Vista was rushed to market. In every case, the only resort available was to upgrade them to XP. I say upgrade because the stability and performance after moving them to XP was remarkable. Every Marine was glad to have the reboots snappy and system stable. Most of them just figured the slowness of their computers was due to the laptop and not due to the bloated operating system Microsoft released.

Only one of them I was able to salvage. I found a nice little hack to reset any users password using Linux and some intuitive programming. This is definitely one of those “must have”’s for the toolbox. The funny thing was, once I restored the Marine’s password, he asked if I could put XP on his laptop just because Vista was so annoying, bloated and slow.

I was also reading a story on how RedHat plans to capitalize on Microsoft’s release of Vista and the slowdown in the economy. I guess both of these type of events have, historically, led to the adoption of alternative software and operating systems. I really hope so. It would be nice to see some more competition out there. Mac has made a nice stand recently with their products. I guess we will see.

For me, I look forward to the late November release of Fedora 10. I’m going to be building up a new computer based on the “Ultimate Budget Box” on Ars Technica’s website. Sub-$500 isn’t bad for a full system with speakers, LCD monitor, keyboard, mouse, etc. Plus, it only pulls 90 watts which will help with the electricity bill.

Anyway, I guess this is all wishful thinking.

One of my biggest hurdles I have come across since taking on Java is really getting my head wrapped around the OOP (object oriented programming) idea. Most of my previous experience wtih visual basic and php was procedural programming. Because of this, my mind is stuck thinking in those terms.

All the e-books I have been going over describe OOP as something that “should” be easy to grasp. A class is a classification of an object. An object is a noun, like a dog, that can be described attributes or fields: four legs, two ears, two eyes, brown, tail, etc. A method is how that dog interacts with other objects: playFetch(), catchFrisbee(), peeOnLeg(), etc.

Okay, so that seems pretty simple. I get these things. However, I don’t see how the hell I can relate that methodology to creating an application for LDAP or even a simple calcualtor for Marine Corps Cutting Scores (the score that gets us promoted).

Luckily, the internet has a plethora of information and I found it on a Stanford student’s website. Jos Claerbout wrote the paper back in 1999. It isn’t on the intricacies of Java. Since OOP is a method or style or paradigm of programming, it doesn’t change as much over time so the age of the document is less relevant than its style.

Mr. Claerbout’s paper is called Don’t fear the OOP. He uses a trashy western novel as his focus to describe OOP. Each idea is presented in “pretty” colors. If in green, the idea is discussed in terms any literate human could understand. If in yellow, it is a bit more programmatical but still not full fledged “programming talk”. And, if in red, it is all about the code. I can’t say I have ever read a paper that used these styles of teaching but it works. It has been a great reference to put me over that edge so I can get beyond the rut I’ve been stuck in.

The internet really is a great place…

I have been flipping between Windows and Linux for quite some time now and I’ve finally decided to stick to Linux for the remainder of my “vacation”. I’ve been looking into object oriented programming for a while. I think it’s time I either get serious about technology or get out of the sector.

Java offers a unique opportunity. Sun has announced plans to open source java and it is beginning to take shape. I think this will help guarantee it will be around a while. On top of that, Java and C# share a lot of similarities so it won’t lock me in to one language for life. I find I actually use more Java based programs than C# based. So, I began looking into learning Java and found that it is a real pain trying to get any software in this part of the world. I plugged in my linux hard drive and found that I already had Eclipse installed (an open source IDE (Integrated Development Environment)). Next thing I knew, I had everything in front of me to begin coding away. The best part is, it is all free. Free as in beer. Free as in speech.

A little searching on the web found a plethora of Computer Science courses related to OOP and Java. And people wonder why I love the internet and open source so much.

The other day I was contacted by a Cpt Miller with the Connecticut Army National Guard (CTARNG). It turns out that the entire CTARNG uses the program I wrote called Active Directory UserMod Assistant. Cpt Miller needed some modifications made to make it work in his environment. I was able to help him out with his mods. It was a bit odd getting a request like that in Iraq. He didn’t know I was here but it was nice knowing that the program I wrote is helping out the Military.

The tricky part was coding without Active Directory and without any of my reference materials. The changes he was looking for were fairly trivial. I was just excited to do some actual work on a computer besides another roster in excel.

I’ve been having a strange issue with a PCMCIA card on my wife’s computer. Every time the machine is rebooted, you are required to “Scan for Hardware Changes” in device manager. It does not automatically detect that the PCMCIA card is still plugged in. After searching google high and low for a solution, I thought about seeing if I could write a script that would automatically run a hardware scan at logon. Here is what I came up with:

1. Download DevCon.exe from Microsoft: DevCon.exe
2. Extract either the 32-bit or 64-bit executable to C:\Windows\System32\
3. Create a file called: “devcon_rescan.cmd”
4. Put the following text in it:
   @echo off
devcon.exe /rescan
5. Copy the file to C:\Windows\System32\
6. Open the registry editor: Start –> Run –> regedit
7. Go To: HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
8. Create a new string value called: DevCon
9. Right click the new value and select Modify. Type in the path to the batch file you made (i.e. “C:\WINDOWS\SYSTEM32\devcon_scan.cmd”)

Hope this helps somebody.

I finally got around to the latest version of adumass. This was a major release as it fixed some pretty serious bugs and also greatly improved the UI and backend code. I also added a few functions for data validation. Thanks to all those that have helped and submitted support requests. The next version should have a translation pack for those users that don’t habla englais.

So, I am pleasantly surprised with Fedora 8. This has to be the best release yet. So far, the only thing I am missing is Cinelerra. I’m having some dependency issues with the freshrpms repository so I guess I just need to compile from source. The only other issue I have had is with NetworkManager-vpnc. Removing NetworkManager and reinstalling it form the development tree fixed the issues. I check the changelog and it looks like the fixes should make their way into the tree.

Other than those little things, everything works like a top. I am constantly amazed at the quality of software put out by the community. It’s too bad more people don’t see what OSS does and can do for them. I can’t thank the community enough. With their help, I’m able to do everything I could ever imagine on my pc (and more). They are the ones who have and will be helping me keep in contact with my family while I am deployed to Iraq. Thank you!

I just ran across a great cgi:perl script for running anonymous proxies. Its called CGIProxy. An easy way to find it around the net is to google: nph-proxy. Also, here is a link to the home page for the beta version: CGIProxy Beta.
