Still able to build PC systems

This weekend has been something of a success for me on the PC hardware front. Earlier this year, a series of mishaps rendering my former main home PC unusable; it was a power failure that finished it off for good. My remedy was a rebuild using my then usual recipe of a Gigabyte motherboard, AMD CPU and crucial memory. However, assembling the said pieces never returned the thing to life and I ended up in no man’s land for a while, dependent on and my backup machine and laptop. That wouldn’t have been so bad but for the need for accessing data from the old behemoth’s hard drives but an external drive housing set that in order. Nevertheless, there is something unfinished about work with machines having a series of external drives hanging off them. That appearance of disarray was set to rights by the arrival of a bare bones system from Novatech in July with any assembly work restricted to the kitchen table.There was a certain pleasure in seeing a system come to life after my developing a fear that I had lost all of my PC building prowess.

That restoration of order still left finding out why those components bought earlier in the year didn’t work together well enough to give me a screen display on start-up. Having electronics testing equipment and the knowledge of its correct use would make any troubleshooting far easier but I haven’t got these. There is a place near to me where I could go for this but you are left wondering what might be said to a PC build gone wrong. Of course, the last thing that you want to be doing is embarking on a series of purchases that do not fix the problem, especially in the current economic climate.

One thing to suspect when all doesn’t turn out as hoped is the motherboard and, for whatever reason, I always suspect it last. It now looks as if that needs to change after I discovered that it was the Gigabyte motherboard that was at fault. Whether it was faulty from the outset or it came a cropper with a rogue power supply or careless with static protection is something that I’ll never know. An Asus motherboard did go rogue on me in the past and it might be that it ruined CPU’s and even a hard drive before I laid it to rest. Its eventual replacement put a stop to a year of computing misfortune and kick-started my reliance on Gigabyte. That faith is under question now but the 2009 computing hardware mishap seems to be behind me and any PC rebuilds will be done on tables and motherboards will be suspected earlier when anything goes awry.

Returning to the present, my acquisition of an ASRock K10N78 and subsequent building activities has brought a new system using an AMD Phenom X4 CPU and 4 GB of memory into use. In fact, I writing these very words using the thing. It’s all in a new TrendSonic case too (placing an elderly behemoth into retirement) and with a SATA hard drive and DVD writer. The new motherboard has onboard audio and graphics so external cards are not needed unless you are an audiophile and/or a gamer; for the record, I am neither. Those additional facilities make for easier building and fault-finding should the undesirable happen.

The new box is running the release candidate of Ubuntu 9.10 and it seems to be working without a hitch too. Earlier builds of 9.10 broke in their VirtualBox VM so you should understand the level of concern that this aroused in my mind; the last thing that you want to be doing is reinstalling an operating system because its booting capability breaks every other day. Thankfully, the RC seems to have none of these rough edges so I can upgrade the Novatech box, still my main machine and likely to remain so for now, with peace of mind when the time comes.

Firefox 3, RealPlayer, Ubuntu and BBC’s iPlayer

With the record attempt due today for Firefox 3 downloads, I thought that it would be a good time for me to update my advice for getting BBC’s iPlayer going in Firefox running on Ubuntu. First, you need RealPlayer 11 for Linux. Once downloaded, the file RealPlayer11GOLD.bin needs to be made executable before running it with administrative privileges. The following command do this:

chmod +x RealPlayer11GOLD.bin

sudo ./RealPlayer11GOLD.bin

There is a catch though and it is that while the RealPlayer 11 installation is seamless for Firefox 2, the same cannot be said for Firefox 3 because directory locations have been changed such plugins are now found in /usr/lib/firefox-addons/plugins. The result that copies of or symbolic links to nphelix.xpt and nphelix.so are needed in that location. The following commands do the trick:

sudo ln -s /opt/real/RealPlayer/mozilla/nphelix.xpt /usr/lib/firefox-addons/plugins/nphelix.xpt

sudo ln -s /opt/real/RealPlayer/mozilla/nphelix.so /usr/lib/firefox-addons/plugins/nphelix.so

To cap all of this, I have seen advice that libtotem-complex-plugin.so needs to be removed from the Firefox plugins directory as well. I am not sure about this but I did that and all is working well for me. Let’s hope that continues to be the case.

Succumbing to Temptation: Ubuntu Studio

The fancy artwork that comes with Ubuntu Studio does look appealing so I got lured into converting my vanilla Ubuntu 7.10 into something a bit more avant garde. The theme’s all very dark (you can have a peek here; file size is 1.1 MB) but it looks very smart, even if the merging of application title bar and top desktop panel due to their having the same colour and texture is a little disconcerting. My momentary lapse of discipline also got me adding a whole array of audio, graphics and movie applications that I may never use; it’s good to have them if I ever fancy a fiddle but removal is not off the agenda either. The other thing that came with the package was an alternate kernel that looks as if it might be of the real time variety, at least if the "rt" in its package name is to be believed. The main reason for mentioning that is that VMware has ceased working so I need to snag the correct kernel source code to get things going again. Let’s hope that it’s a successful venture…

Update: After a spot of poking, Synaptic offered up the required kernel header files and VMware was reinstated with only a modicum of effort. All’s well that ends well.

iTunes: a resource hog?

When I first started to use iTunes, it very much played well with other software applications running. Then, a few versions later, the playback began to suffer with iTunes running in any way other than on its own. A solution that I have is to fire up the Windows Task Manager, go to the Processes tab and find iTunes.exe in the list. The next thing is to right-click on this, select the Set Priority and change the setting to Above Normal. Windows will warn you about what you are doing but it usually doesn’t cause any other problem. Yes, it sounds a bit extreme but it always solves the playback problem.

So long as iTunes is merely playing music, all is well. However, when it starts ripping CD’s, it’s a wholly different matter. That is a CPU intensive operation and setting the process priority to Low is a very good idea. I recently got caught out by a default setting of ripping any music CD inserted into the PC and, at Above Normal priority, the PC got locked up. Eventually, I got things back under control and lowered the priority. Needless to say, iTunes will just list the contents of an inserted CD from now on. I have learnt my lesson; keeping the command line open to get at command line process tools would be a very good idea for the future, especially as I know where to find these on the web.
