Safari Memory Hog

Safari (web browser on the Mac) does annoy me now and again by pretending it needs lots and lots of memory which then slows my whole Mac down.

I’ve just had to force quit Safari which was demanding 5.16GB of virtual memory. This was playing havoc with other stuff I was doing on the Mac.

Once I quit Safari, all was fine and everything speeded up.

I am not sure why Safari gets this demanding with memory, but it does happen quite a lot, so every so often I have to quit Safari and restart.

802.11n’ised WET54G

I am currently looking for a 802.11n version of the Linksys WET54G which I have been using with my EyeHome.

The Linksys WET54G is an ethernet wireless bridge, basically it enables you to connect (wired) etherent devices to a wireless network.

As you might guess from the name the WET54G is an 802.11g device which has been working okay in conjunction with my EyeHome. However the limitations of the 802.11g wireless network means that I have had some buffering issues with some video files.

I am hoping with an 802.11n network that I will solve these buffering issues and will be able to stream my EyeTV recordings (in the main BBC recordings) smoothly without stuttering.

The problem I have is that Linksys don’t (yet) make an 802.11n version of their WET54G. I am not sure which 802.11n devices do work with Apple’s implementation of 802.11n.

Another 802.11n Airport Extreme as a WDS node for me is not really a solution as WDS effectively halves the wireless bandwidth.

So if you have any suggestions leave me a comment with a recommendation.

Amazon Digital Book Sells Out!

Despite a lot of scepticism and negative coverage about Amazon’s new digital book reader, the device has sold out according to the BBC.

Amazon’s Kindle e-book reader has sold out despite scepticism about whether the device will prove popular. A notice on the Kindle pages on the Amazon web store said “heavy customer demand” for the device meant it would be out of stock until 3 December. Since its launch on 19 November the device has been widely examined but opinions about it are mixed.

Looks like people are interested in this digital book reader. Is this the device for e-books what the iPod was for digital music? We will have to wait and see.

“it’s too flawed to be anything other than a novelty”

The Guardian has reviewed the Sony VAIO UX1XN and found that though a wonderment of design, it is somewhat fiddly to use.

But delightful though this notebook is to look at and hold, it’s too flawed to be anything other than a novelty.

UX1XN

The review also mentions issues with the keyboard and the tablet input, which I both agree with.

… there’s the first disappointment – the keyboard. You wouldn’t want to do much more than tap out an email on it, as the size of the keys make it no good for touch-typing. Double-thumb input is feasible, but the tiny keys make it hard to be accurate.

and

The touchscreen is a nightmare. Fiddly to calibrate, it failed to retain its settings and eventually refused even to acknowledge that it was in fact a touchscreen. So I resorted to the pointing device.

I still think it is useful and not as flawed as the review makes out, and the more I use it, the more uses I find for it.

Installing Ubuntu 7.10 as a Guest OS on Parallels

After having a few problems and reading a variety of guides on installing Ubuntu as a guest OS on my Parallels installation on my iMac I finally managed to get there after a suggestion from KevanV on Jaiku.

Go to the Ubuntu website and when you download the ISO ensure you that you check the box which says Check here if you need the alternate desktop CD. This CD does not include the Live CD, instead it uses a text-based installer.

Then when you install Ubuntu ensure you use the text based installer.

Also when asked which screen resolution you wish to use ensure that you check 1024 x 768 only.

Once installed the graphical user interface works just fine.

802.11n

I was playing around with my new 802.11n Airport Extreme base station seeing how I could maximise the performance of the wireless network.

I switched to a pure 5Ghz 802.11n network and then using Chicken of the VNC on my work MacBook Pro made a connection to my iMac and set EyeTV going. I was quite impressed with the screen refresh, however it wasn’t good enough (even at 300Mbs) to watch remotely.

I also undertook some file transfers and was very impressed with the speed.

I had to switch back to b/g compatible mode which reduced the 802.11n speed down to 130Mbs, but as I have a fair few legacy devices I need the b/g compatability. I will at some point add an Airport Express or my older 802.11g Airport Extreme to one of the LAN ports of the newer base station to enable me to have a dual wireless network, one a pure 802.11n network and a b/g network.

The only problems I had were when I switched back to b/g compatible mode, I forgot to reset the security back to WPA/WPA2 mode which meant that my HP TC1100 Tablet failed to connect back onto the network. I had to reset the wireless security and then reboot the TC1100 before it would connect correctly to the wireless network. Other devices worked fine, butI suspect that was because theTC1100 hardware doesn’t support
WPA2.

I also had to delete and add back my wireless Canon MP600R wireless printer.

I am impressed with the new 802.11n Airport Extreme and I haven’t even started to utilise the full functionality of the device.
