Opinion: "Confessions of an Ubuntu Fanboy" Response

| | | |

Just got done reading, "Confessions of an Ubuntu Fanboy". While I'm glad the author has decided to be more practical in his promotion of Linux and Ubuntu, I strongly disagree with some of his conclusions and I'll cover them below.

I have been using Linux for about 15 years now and over the course of that time I've helped more people than I care to count with Linux installs, removals and everything in-between. I've seen people try Linux out for a few days and give up on it. I've seen people tough it out and become valued members of our local Linux community. Linux isn't for everyone and choice is good. I no longer advocate Linux for someone who isn't willing to learn new things. I quit trying to push it on people and now I'm somewhat selective in helping people the second they say they want to try Linux. I state up front that there is a learning curve and that they will need to expect it. If I sense that they don't have patience to learn new things, I don't even bother.

The problem with the article in question is that the author seems to want to try to make Linux for everyone and in doing so, he advocates violating some important tenants. He primarily focuses on Windows users but it could be any proprietary OS or applications.

Video: KVM Architecture Overview

| | |

I downloaded all of the videos offered from the Red Hat Virtual Experience 2009. They made them available as Ogg Theora .ogv files so I didn't even have to convert them. They are of moderate to low quality especially with regards to audio... so they can be a little annoying but the presentation material is generally top notch.

In this video, Andrew Cathrow of Red Hat spends about 23 minute explaining what KVM.

Video: RHEV Presentation

| | |

The Red Hat RHEV presentation lasted for about an hour and forty-five minutes and I video taped it. I can only relase the first 23 minutes of the presentation which is where the slides ended. The demo after the slides contained details about the upcoming (and currently in beta) RHEV for Desktops product which can't be shared because it is subject to change between now and the GA release.

As an attachment to this article you will find the PDF of Tom's slides.

The video should work in Firefox 3.5 and above... or any browser that supports the HTML 5 video tag and Ogg Theora video. In-browser playback isn't always perfect so if desired, right-click on the video and select "Save Video As..." to download and play locally. The videos is approximately 105MB.

If your video player can't handle Ogg Theora then I recommend you check out VLC media player.

Opinion: Apple iPad - I Perceive Ample Defects

| |

Ok, the dust has had time to settle after Apple's announcement last week of their upcoming iPad device. There has been plenty of praise for the new device and even some criticism. Given the title of this entry, it is clear that I'm here to criticize it.

A New Form Factor?

During his presentation Steve Jobs railed against the Netbook form factor and said they were just cheap, slow laptops. While that might have been true for the first generation of Netbooks, the second generation (with 1.6GHz Atom H/T CPUs) have been quite usable. In fact, I wrote this on one. Intel has followed up with an even more capable Atom processor that is just starting to appear in newer Netbook models. It appears more generations of netbooks are coming: those with the newer Atom CPUs, and those with ARM CPUs. One will speed up the Netbook, and the other will reduce its capabilities and make it cheaper.

I suspect the iPad is what it is because Apple decided it couldn't compete on features and price against the Netbook... so they decided to change the game. I think several of the major PC makers wish the Netbook would be declared a fad and just go away. Why, because there isn't a lot of mark-up on Netbooks and the competition is fierce. Apple wanted a device that would be inexpensive to manufacture yet something in a category where they could do what they always do... price it with a large profit margin. Amazon has done quite well with the Kindle and Apple has done quite well with the iPhone / iPod Touch so why not combine the two?

The sad thing is that Apple has basically delivered a Netbook but by chopping off the keyboard (and all of the I/O ports), giving it a touch screen, and crippling it significantly in several ways, they have everyone convinced that it is a new form factor. This is aided by the fact that it is reminiscent of devices from the Star Trek universe. In writing this article, I hope to expose the iPad for what it really is and stay out of Steve Job's reality distortion field.

Screencast: SELinux Demystified

| | |

I slapped together an SELinux presentation for the BozemanLUG and some people said they wished they could have attended it but missed it, so I decided to record a quick screencast.

Please note, that I do not claim to be an expert on SELinux but I do present the basics. If anyone with more SELinux knowledge notices any mistakes, please let me know.

You can find it here:
selinux-demystified-bozemanlug-jan2010.ogv
91.2MB, ~34 minutes

It is an Ogg Theora .ogv file that I recorded with gtk-recordmydesktop. Right-click and "Save as..." to download. Or if you have a newer version of Firefox with .ogv support, watch it in your browser. The better experience is probably to download it. If your preferred media player can't play .ogv files, I recommend you check out VLC Media Player.
