Filterset.G and Adblock


I saw this post yesterday that mentioned Filterset.G.  I have been using Adblock for a while to help block web ads.  Filterset.G is a set of filters for Adblock.  I have been pretty impressed with the effectiveness of these filters, in fact it is able to block text-based Google Adsense ads.

OpenDNS


OpenDNS is a company that provides DNS resolving for networks or individual computers.  They offer some interesting features:


  1. Phishing protection - Will display a warning page when attempting to view a known phishing site.

  2. Increased speed for browsing - OpenDNS has a large DNS cache to speed host name lookups.  In addition to this their DNS servers are located near the computer making the DNS request.

  3. Fixing spelling mistakes - OpenDNS will help with common spelling domain name spelling mistakes


I am going to try this out on our network at home.  Unfortunately this really does not work for me on my laptop, and I think that they need to call the following situation out more clearly.


newTunes


newTunes seems like a pretty cool dashboard widget.  It will let you know when new music is in the iTunes Music Store for any of the artists in your iTunes library.


Unfortunately, it doesn't work well for me.  I installed it on Friday, and on Monday it still doesn't display anything.  The problem is that the widget launches an AppleScript that, I believe, is building the list of the artists and the local tracks for those artists.  On my library that has 7800 tracks, this takes a long time. 


I think that it would be better for this widget to parse the iTunes Library xml file itself.  (I believe that Apple has an API to do this, this is what iPhoto uses to show the list of tracks for slideshows.)  This would be a lot faster, and would allow the widget to show status while the list is being built.

Power-Pipe


PowerpipeA while ago, my wife wrote about how we are trying about finding ways to save money on energy.  The Power-Pipe is a way to recover the heat energy from waste water.  To install this, you would replace a section of the main PVC drainage pipe, with a copper pipe, that has smaller pipes coiled around the large one.  Cold water is run through the small pipes, where it will acquire heat from the drain pipe, and then it would run into the hot water heater.


Supposedly the Power-Pipe will increase the cold water from 10 to 24 degrees C.  This is possible since 90% of all hot water energy goes down the drain, and the Power-Pipe can recycle as much as 60% of this energy.


Unfortunately, the website for the US residential distributer is not up.  On Canadian site, the Power-Pipe costs between $270 - $1200.

minimum browser requirments


I find it interesting sad when websites have pretty old browser requirements.  Here are the requirements for logging into XM Radio's account login


Minimum Browser Requirement:


Cookies are enabled

Microsoft Internet Explorer - Version 5.01 and higher

Netscape Navigator - Version 4.x and higher

AOL - Version 7 and higher


The problem here is that they don't recognize Firefox 1.5.0.4 as newer than Netscape Navigor 4.

Mac OS X calling home


With the 10.4.7 update of Mac OS X, the OS is calling back to Apple's servers periodically.  There is a new process called dashboardadvisoryd with makes the tcp connections.  The tech note on 10.4.7 has this entry:


You can now verify whether or not a Dashboard widget you downloaded is the same version as a widget featured on (www.apple.com) before installing it.



If this were just for this purpose, this check could have been done when installing a widget.  I assume that this process is also checking the currently installed widgets to see if they are up to date.  I think a better implementation would be to have a button in the area of the screen that shows all of the installed widgets, that would check for updates.

iTheater


ItheaterNow you can look like Geordi too.  The iTheather simulates a 50" video screen for iPods or any thing that can output video.
