Ubuntu responds to Firefox bug

Maybe less than a week ago there was a pretty neat event called ConSecWest. It's main purpose is for white hat security researchers to gain recognition for successfully exploiting popular Internet software such as Firefox, Internet Explorer, and Google Chrome, among others. A very cool program! Though, I think the researchers deserve more than $5,000 for finding a bug--but, how can one place value on recognition? A prominent ex-NSA security researched Charlie Millier who was interviewed at tomshardware.com discovered severals flaws at the event one of which exploited Firefox.

Two things need to be done. First, props need to be given to the Firefox team for quickly resolving these flaws and releasing Firefox 3.0.8.

Second, though, just because a new version of the software is available does not mean that a system is now protected against the vulnerability. But, that is not so far from the truth. The most important step is to actually update your system and for a brief second I thought that maybe I would have to update my system manually. I mean, the new version was released so recently! Once again, I doubted the Ubuntu distribution probably due to being scarred by years of using Fedora Core. The moment I discovered there was a new version of Firefox, Ubuntu had notified me of new updates! To my surprised, it was Firefox 3.0.8... Excellent work Ubuntu! Your timeliness is very appreciated.

Intel Atom!

I've recently decided replace two of my home servers with an Intel Atom system. The Atom is a low-power CPU which comes in various flavors which you can read about at wikipedia.org. What I will tell you about is the huge success that my upgrade has been and how extremely happy I am with this processor. You will also find a detail listing of the various components that compose my system, how the system is being used, and my overall opinion of the processor.

Components

  1. Athenatech Black Steel A100BB.270 Micro ATX Media Center / HTPC Case
  2. Kingston 2GB 240-Pin DDR2 SDRAM DDR2 533 (PC2 4200) Desktop Memory Model KVR533D2N4/2G
  3. ECS 945GCT-D Intel Atom FCBGA 437 Intel 945GC Mini-DTX 200x170mm Motherboard/CPU Combo
  4. Transcend 4GB Compact Flash (CF) Flash Card Model TS4GCF300
  5. LG 22X DVD±R DVD Burner Black SATA Model GH22NS30
  6. Addonics CF - SATA HDD Adapter
Total Price: $251.44

I went with the ECS 945GCT-D motherboard because it comes with a PCI-e slot. This is a very useful feature which will increase the longevity of your system giving you room for any possible future upgrades. For me however, I'm using the slot to stow my external RAID controller card which is the core component of my 5 terabyte data storage solution. The motherboard claims it supports a maximum of 2gb of RAM--1gb stick in each slot. Though, I'm having no issues with a single stick. One last thing I'd like to mention is splurge and purchase the highest quality compact flash card you can afford. I experimented with several models and found them lacking in performance. Worse, a Kingston stick I first purchased had constant data corruption issues. Avoid! The CF card listed above will not disappoint featuring 45Mb/sec transfer rate.

I am extremely happy with the performance of this system. It makes absolutely no noise though it has a PSU fan and two small case fans. It is ideal for my home server needs and this box currently serves the following purposes:

  • MySQL Database Server
  • Apache/PHP Web Server
  • DNS Server
  • NIS Server
  • NFS Server
  • MythTV Front/Backend
  • SVN Server

All of the above services took a solid week and a half to match the flawless configuration of the systems it replaced. During this process, I experimented with several Linux distributions including Fedora Core 10, Ubuntu 8.10 Server, and Ubuntu 8.04 Server. Ultimately, I had the most success with Ubuntu 8.04. It was an interesting experience attempting to configure the system with FC10. I had configured almost all of the above services but failed to get sound working with MythTV. I won't get into the details of the problem but my conclusion is that Ubuntu has come a long way not just as a Desktop but as a Server. The configuration of Ubuntu was much easier not just because it is better documented but the overall higher quality of the packages offered by Ubuntu makes configuration of the above services a much better experience. It is worth mentioned that because I only have 4 GB of disk space on this system I could not afford to install unused packages (e.g. Ubuntu Desktop). The FC10 base install took ~1.4GB compared to Ubuntu 8.04 which took ~500MB. After installing all the necessary packages to support my configuration, my disk usage is:

/dev/sdg1              3753400   1723876   1840364  49% /

Which is perfect.

This $250 system is a perfect home server. I'll take it a step further and dare to mention that running X (specifically, LXDE) on the Atom system is just as responsive as on my dual-core box. Unless you need heavy computing power (e.g. gaming/video editing) you will be very happy with the Atom processor. I can't wait to build another one.

Pandora + Replay Media Catcher

I've recently discovered, when Replay Media Catcher v3.01 downloads Pandora streams, they are saved as a m4a file format. This was rather new as previous versions saved the format as mp3. I've no issues with various formats, but there was a problem. I was hearing the quality of the media degrade severely when playing the media file from within iTunes or QuickTime Player. Indeed, iTunes reports the bit rate (quality) of the media as 64 kbps, which is garbage as it's worse than FM quality.

A deaf guy could tell that Pandora plays the track at a much higher quality. The exploratory person that I am, I wanted to see if the problem lied within iTunes. Since Windows Media Player could not open the m4a file, to continue with my test I first had to convert the file to a more familiar mp3 format. A quick Google search turned up a free, easy to use, m4a-to-mp3 converter. After installing the software and converting the media, miraculously, the quality of the song returned to normal. Now you can once again enjoy decent 128 kbps quality!

I did a little browsing around, and stumbled into a Bitcartel Blog entry explaining in some detail about this recent Pandora change. The blog also suggests a possible solution.

PNSQC 2008

For the first time, I had the opportunity to attend the Pacific NW Software Quality Conference (PNSQC) and wanted to share a bit about my experience with anyone interested about the event. The non-profit two day conference took place at the convention center in Portland, OR and was filled by individuals involved in testing from IT to managers. The theme this years was collaboration and the agile methodology--though, the topics were variety as it's not difficult to incubate collaboration into any subject. In regard to the agile methodology, I was rather disappointed by the attempts made to glorify the idea. Simply put, it has been around for a long time and is obviously not a magic bullet in fixing your development problems--anyway, the concept was beaten into my head over and over throughout the two days. Fine. At the end of the day it comes to writing high quality code and the methodology can only take you so far.

Of all the presentations I attended, there are only a few worth mentioning.

Collaborative Change by Debra Lavell (Intel)

I had the pleasure of hearing Debra discuss how she implements change in a large, mature organization. I strongly believe that change is something to strive for. There are always ways in which something can be improved upon and effort should be made to achieve improvement. Problem being, people tend to avoid going outside of their comfort zone and Debra's job at Intel is to encourage teams to go outside of this zone, admit to the problems they are making, and take the necessary steps to implement the already known solution.

I was impressed with Debra's presentation. Her charismatic speaking-style (which I can only assume is a necessity in her line of work in convincing people to adopt change) was a change compared to some other presentations.Though she presented quite a bit of information, what I walked away with were some concepts applied by Debra to achieve change. I took note of these concepts as a way to remember qualities required to facilitate change. And here they are,

  • Conduct retrospective three times throughout a project life cycle
  • Reuse existing solutions
  • Create an action plan
  • Include a neutral facilitator
  • Illustrate gaps and areas for improvement
  • Shape the environment for change
  • Reward change

She covered all the topics, something I will not due here but leave it as an exercise to the readers to gather further insight.

Selling Your Idea to Management - Steve Smith

Steve Smith quite possibly presented the best presentation of the entire event. This topic had little to do with testing, collaboration, or agility. Though, each and every individual attending this presentation walked away with great insight in how to better sell an idea to management (or anyone for that matter). Perhaps, you need to convince management that your test department is greatly under-staffed? Or, maybe you want to convince your team that language X or library Y should be used for the upcoming project? Though we won't always have our way, Steve presented three simple, life-changing concepts which can greatly increase your success of others adopting your idea. The three concepts are,

  1. Change the perspective. The idea must be restated to change the perspective from how it benefits you to how it benefits the manager/organization.
  2. State the benefits of the idea. If we adopt X, the benefits are...
  3. Discuss the consequences if of doing nothing. Doing nothing is the default, state the downside of doing nothing.

Enjoy! I hope to see you there next year.
