A little while back I was chatting to someone about SEO and the power of outgoing links. In the bad old days your client would ask you to build a web site that had no links leaving the site or put some horrible confirmation page asking you that you are leaving!
Whats interesting here is that by not having any external links you are reducing your interconnections with other sites, and so reducing your ranking in search engines. Not only do most search engines allow you to search for linked pages but each additional connection in either direction will increase the weighting that matching symbols (words) in those documents have the same implied semantics. This is just like a neural network where each additional connection re-enforces the bond further increasing the chance of a pattern match.
Add to the fact that incoming links, trackbacks and pingbacks are very common on blogs and other modern publishing tools and those implicit back links become explicit.
So if you want people to link to you, you should link to them.
So I got some helpful feedback on my last post from John McCrea who is VP of Marketing for Plaxo. So I logged back into Plaxo and had a little hunt around and after about 5-10 minutes found my addresses.
My initial reaction was Doh! what an idiot I was, but then after a few minutes reflection I started to think about user interface design and intuitive learning. When I showcase new functionality to my users, they will often give feedback about how easy a feature is to use or find. Often as developers or familiar users of a system we don’t see that something might not be named or located in the most natural place.
So I though I might also give some feedback to Plaxo that might help improve the user interface.
This is where the confusion started for me:
Option 1 leads you to the old Plaxo address book system
Option 2 leads you to an import wizard to get your address book from Outlook, GMail etc
Option 3 doesn’t contain any of your old address book “connections”
So these are my thoughts:
- Links with nearly the same names but going to total different actions is confusing
- Option 3: The domain language seems confused, surely the people I have already shared my address book with are already “connected” in someway. Maybe that connection only allows address book features and not all the new features.
- Option 2 doesn’t seem to support importing from option 1 (You wouldn’t need this option if they were already connected)
- Option 1 feels like a skinned version of old app and not really integrated into the whole experience
I’ve been an occasional user of Plaxo (just the address book) for the last 3 years, using it to keep a few important addresses up to date. Anyway today was the first time I had used it since they launched Pulse, and guess what all my contacts have gone!
Now that’s not very clever for a social networking site and reminds me what Duncan would say about Web 2.0 and making sure all you data is public, readable in some open format and ideally distributed over the interweb. If fact this really goes back to why “data bases” were created in the first place: data lives longer than applications: well not in Plaxo’s case.
Well Kiran and I both gave our first public presentations at the OverTheAir mobile conference at the Imperial College.
Kiran talked about Agile & Mobile development and I talked about Progressive Enhancement
So the wifi seemed to work pretty well out of the box but I noticed after prolonged use it would just suddenly freeze and the only way to make it come back was to reboot. (You couldn’t even reload the module or restart networking stack).
You can tell if this will be a problem for you by running iwconfig: if you have lots of Invalid misc errors and the signal and noise levels are fixed at -60dBm then you will want to switch from the ipw3945 module to the iwl3945.
To try it out:
sudo modprobe -r ipw3945
sudo modprobe -r ieee80211
sudo modprobe -r ieee80211_crypt
sudo modprobe -r mac80211
sudo modprobe iwlwifi_mac80211
sudo modprobe iwl3945
Now if you run iwconfig you should see wlan0 (plus wmaster0 which we’ll just ignore). If it’s called wlan0_rename then you run
sudo nano /etc/udev/rules.d/70-persistent-net.rules
Comment out the line reserving eth1 for ipw3945 module.
To make this all permanent you need to add the iwl3945 and iwlwifi_mac80211 modules to /etc/modules
sudo echo iwlwifi_mac80211 >> /etc/modules
sudo echo iwl3945 >> /etc/modules
And now stop the ipw3945 and dependencies from loading by blacklisting them
sudo echo blacklist ipw3945 >> /etc/modprobe.d/blacklist
sudo echo blacklist ieee80211 >> /etc/modprobe.d/blacklist
sudo echo blacklist ieee80211_crypt >> /etc/modprobe.d/blacklist
sudo echo blacklist mac80211 >> /etc/modprobe.d/blacklist
I had to start the install CD in safe VGA mode and have not got the slash to display yet.
To get sound to work you don’t need to recompile your kernel or go back to an earlier version just follow method G one this page:
Gutsy Intel HD Audio Controller
sudo aptitude install linux-backports-modules-generic
sudo gedit /etc/modprobe.d/alsa-base
In the editor, add the following line at the end of the file:
options snd-hda-intel model=dell-m42
Save the file and reboot to get sound working correctly.
If sound is too low, go to Volume Control’s Preferences and add “Front” (and any other playback tracks) and make sure they are set to the maximum.
We may end up getting RESTful smart contracts for free due to all the goodness in the current design. This could lead (my client).com to an unheard of level of security and possible make it the most high profile public implementation of smart contracts to date. Watch this space

Web 3.0 Semantic Web
Due to our data being so dynamic we may have the opportunity to go from web 2.0 to web 3.0 and again this could make this one of the first killer semantic web applications.
Decoupling Resource selection from Representation selection in our Urls
This will allow resources (domain objects/documents) to be selected (think SQL WHERE clauses) and presenters re-used by the client editors without specific coding by developers. So a url like “/video/skins/latest” could return all videos tagged with skins or possibly any resource tagged with video and skins. What we are aiming for is totally dynamic / fluid urls with uses we never imagined.
Editors will be able to mashup YouTube videos, Facebook items, MySpace pages, Flickr images etc. into pretty much any where on the site. Users will be able to mashup client content / videos onto any other site.
Allowing users to rate each others content, interact with client content / users and other social networking sites and generally use the site in new and interesting ways
We will be totally embracing web caching so that all non current user specific content will be cache able. User specific content will be included client side (in an accessible way) so containing pages do not need to be made non cache able.
