Does Twittering have a place in Business?

Is there supposed to be a point behind Twittering I asked myself? The site is pretty scarce on describing a particular use for it's service apart from "What are you doing now?". Maybe not limiting it's boundaries is part of it's success?

I'm always willing to try out new technology, I'd describe myself as an early adopter. Now I'm not saying I won't ever sign up and be a fellow Twitter myself in the near future, but from the outside, and without experiencing it firsthand I can't see why anybody would be interested in a rolling commentary of what some other individual is doing right now. I guess if you're into instant messaging (IM) or texting and want to let all your friends or family know what you're up to broadcast fashion, that might be a powerful tool. I'm guessing adding a Twitter to a page would be the best place to put this kind of information.

Celebrity Tweets

A celebrity Twitter on the other hand might be extremely popular in this celebrity obsessed world we live in. Just imagine the sort of Tweets Paris Hilton would send from her Sidekick cell phone! And the hoards of followers that would subscribe.

What about Twitter use in a business environment?

Blogs, instant messaging and texting have all been adopted by the businesses and they all started out in the consumer space, but what business problems could they solve?

I can see them being used internally inside companies for staff to keep line managers updated on what tasks they are working on. After all Microsoft amongst others have found business uses for IM.
Public Relations could be another use, as could musicians and bands keeping their loyal fans up-to-date on tour etc.

To Feedburn or not to Feedburn?

I've decided to try out Feedburner. We use RSS to syndicate content at work and have to use server log file analysis to track them, web-beacon based web analytics packages are good for websites, but you can't add Javascript to feeds, which are pure XML. We've tried using .NET to database the hits we were getting on the feeds, but after a short while of testing we were seeing our database growing quickly in front of our eyes, not to mention consuming our precious CPU cycles.

Feedburner not only takes away the hassle of analysing web feed statistics and subscribers, but adds a lot of other functionality too.

My main initial issues with Feedburner were the following:

* What if Feedburner went bankrupt? All the sites syndicating my feed would be using the feedburner URL (unless I pay for the Pro service). How would I be able to change this back to my own URL or another Feedburner type URL? (hopefully saying goodbye to Feedburner would also still hold true if they went bankrupt?) [UPDATED: On June 1st 2007 Google purchased Feedburner, therefore making bankruptcy much less likely :-) ]

* I can't redirect any current traffic from my old Blogger Atom feed on my shared Windows hosting as I don't have access to IIS through my control panel. The file is an .xml file, and I can't use .htaccess for obvious reasons. I would need to use an ISAPI rewrite tool I suppose, which I probably wouldn't be able to get installed in a hosted environment.

* If I want to later upgrade to the Pro service, I would surely have to keep my Feedburner URL even though I could have a URL hosted on my site with this package just so I keep all my subscribers using the same feed URL. (I guess I could use the "saying goodbye to Feedburner" process above?)

Despite these issues, I've decided that the pros of knowing my subscribers etc out way the cons and I'm now syndicating through Feedburner!

I am wondering however, how Feedburner manage to host so many blogs. I assume they have some serious kit to handle the many requests they get. I would be interested to know what the Feedburner IT infrastructure looks like.

My Blog Is Biased

I've just been reading this article that discusses Blog biases and it made me wonder what mine would be biased towards. Biased opinions aren't necessarily a bad thing and unlike the BBC or other large media outlets who claim to be unbiased, blogs are mostly individuals views of the world. Blogging has made everyone with a computer or a mobile phone a journalist. It's this user-generated content that is powering the "web2.0" revolution.
So, because I'm the only contributor to my blog, and biases are generally formed throughout life based on influences and experiences encountered I can make some good general statements about my biased opinion.

  • Proprietary software or hardware that specifically locks the user into a companies products is bad for the consumer (e.g DRM, Sony ATRAC etc).
  • Open-source software, because it gives power to developers, and free software is always a good thing.
  • Microsoft Windows, because even though it has a stranglehold on the OS market, they still make rather good software, much of which is proprietary, but because so many people have it, the user experience is good, and firms require you to have experience using it.
  • Linux, because we always need an alternative to Windows just for us geeks.
  • Xbox 360, because I since my analogue cassette Walkman in the 80's Sony has done nothing but lock the consumer into its goods using proprietary software and hardware, and I want the PlayStation 3 to fail.
  • Companies that don't listen to their customers needs.
  • Websites that are designed for search engines and not users.
  • Services that make my life easier are definitely a good thing!
  • HD DVD wars; Does the consumer really want to buy another Betamax?
  • Hardware after-sales support. You got my money, now can I have a Vista driver without upgrading hardware less than a year old?
This list has turned into more of a rant and rave about how we've slowing began to accept more and more shoddy service from companies who take our money and run. If I think of anything else I'll be sure to update my list. :-)

ASP.NET Web Accessibility and Visual Studio 2005

I've been using Visual Studio 2005 on a recent project and was surprised that even though it is supposed to feature lots of web accessiblity tools and options, they don't seem to be turned on by default. I'll bring you an example to back this up.
I created a new ASP.NET page, essentially it was a simple form, which when submitted sent an email; similar to a contact form if you like. The form was built within an HTML table, with ASP:Label controls to hold the textbox definitions.
On viewing the page in a browser and examining the source code, I noticed that the ASP:Label controls are converted to HTML <span> tags, which is a little bizarre. After a little research I found that if you use the AssociatedControlID property of the ASP:Label to link to the related textbox the HTML source code produced now uses an HTML <label> tag.
I also figured out that using the ToolTip property of the ASP:Label control renders as the title property of the HTML label tag.

So the following ASP.NET source code:

<asp:Label ID="LblDayMovedOut" runat="server" ToolTip="Day Moved Out" AssociatedControlID="DayMovedOut">
<asp:DropDownList ID="DayMovedOut" runat="server"></asp:DropDownList>
<asp:Label ID="LblMonthMovedOut" runat="server" ToolTip="Month Moved Out" AssociatedControlID="MonthMovedOut">
<asp:DropDownList ID="MonthMovedOut" runat="server"></asp:DropDownList>
<asp:Label ID="LblYearMovedOut" runat="server" ToolTip="Year Moved Out" AssociatedControlID="YearMovedOut">
<asp:DropDownList ID="YearMovedOut" runat="server"></asp:DropDownList>

Would render the following bloated, but accessible HTML:

<label for="ctl00_ContentPLaceHolder_DayMovedOut" id="ctl00_ContentPLaceHolder_LblDayMovedOut" title="Day Moved Out">
<select name="ctl00$ContentPLaceHolder$DayMovedOut" id="ctl00_ContentPLaceHolder_DayMovedOut">
<label for="ctl00_ContentPLaceHolder_MonthMovedOut" id="ctl00_ContentPLaceHolder_LblMonthMovedOut" title="Month Moved Out">
<select name="ctl00$ContentPLaceHolder$MonthMovedOut" id="ctl00_ContentPLaceHolder_MonthMovedOut">
<label for="ctl00_ContentPLaceHolder_YearMovedOut" id="ctl00_ContentPLaceHolder_LblYearMovedOut" title="Year Moved Out">
<select name="ctl00$ContentPLaceHolder$YearMovedOut" id="ctl00_ContentPLaceHolder_YearMovedOut">

Google Reader Mobile Interface - Good, But Room To Improve

I'm a big fan of Google Reader. I tried the first Google Reader interface not long after it was released and couldn't get on with it. It didn't have much going for it. It was hard to use and read articles from, and it was buggy although it was a beta release.
Since the interface was changed however it has progressed in leaps and bounds. It is now my feed reader of choice. I didn't particularly like the Bloglines interface either.

Mobile Feed Reading

I'm a busy person and I don't get much time during the day to catch-up on the news I want to hear about. So after purchasing a Windows Mobile MDA with unlimited 3G Internet access I was on the look out for a decent mobile feed reader.
Even though browsing normal websites with mobile devices is possible, it's not a rewarding experience because not many sites are optimised for the small interface.
Thankfully Google Reader has a fairly decent mobile interface, that includes a mobile proxy to reformat normal web pages to make them much more readable on small mobile devices.
Google have managed to shoe-horn most of the functionality into the mobile version, but it is a lot more buggy than the normal web version. Perhaps some of the bugs I come across are down to buggy web feeds, but Google should be able to find a way around most problems.

Google Reader Mobile User Interface Enhancements

Here are some of the bugs/bugbears I have with the mobile interface (in no particular order)

  • There should be a link straight through to the article on the site in question, not just the summary page in Reader. This will reduce the amount of clicks if you know you want to read the article even without reading a summary first.
  • Why do we need the more... Link when we now have the mark these items as read... Link?
  • When you star an item it reloads the whole page. Can it not return to the list on news items?
  • Some blogs cause http errors, produce no article when you click through, feature loads of links that you need to scroll through to get to the content, or show the summary as being the same as the blog title.
  • I would like the option of being about to read only a subset of my feeds from the mobile interface.

..and finally...

I use the new shared items widget on my blog to let my users know what I've been reading lately. From the web interface you can quickly share feed items with a simple click. This functionality is missing from the mobile interface however. So the work around for the time being is to star each item I want to share with my readers and click the share button on each item when I get on a desktop machine.

The interface is improving all the time, so hopefully Google will listen to its users, because I know I'm not the only one who has views on some of these topics.

Windows Vista Upgrade Advisor and Hardware Incompatibility

Just to recap, I bought Windows XP Media Center edition with an upgrade voucher to Windows Vista Home Premium last year. After sending off all my details to claim my Vista DVD and receiving it, I thought it best to clear some room on one of my hard disks and run Windows Vista Upgrade Advisor before I go any further.
I had previously ran a beta version of the upgrade advisor prior to upgrading my OS from Windows XP Pro to Media Center edition and as far as I can remember all my hardware was compatible (software was another story!).


However... While upgrading my machine to Media Center I also upgraded some of my hardware. I upgraded my wireless 802.11b Netgear MA111 USB stick to a US Robotics 5418 802.11g PCI adapter (This allows for video streaming around my house via my Xbox 360, and also reduces the amount of USB devices I have hanging off the back of my machine).
I was also severely running out of disk space, so I added a SATA RAID card and bought two SATA HDDs so I could set up a mirrored (RAID 1) configuration for a little peace of mind).

After running the upgrade advisor you can now probably guess what devices weren't supported in Windows Vista...Yep, the USR5418 wireless PCI adapter and the Adaptec 1210SA SATA RAID controller, typical I thought!

I have checked the manufacturers' support sections for these devices, but future Vista drivers for them don't look promising. So unless I can find a driver that will work with these devices I don't see much point in upgrading to Vista at the moment. Can you imagine the Aero interface in all it's glory, but no data to access and no web to surf on!! The only other solution is to upgrade these components again, but I am reluctant to spend anymore money on my aging computer.

Hardware Manufacturers or Microsoft?

So who is to blame for this lack of compatibility? The devices aren't exactly that old, Microsoft has had numerous beta versions of Vista available for hardware and software companies to test and develop for, but it seems they want you to buy the latest product instead. Even big companies like Apple had problems with iTunes after the Vista launch.

Cisco CCNA Revision Notes

[updated - 6th April]I've just been going through files on my computer and giving it a bit of a spring clean in preparation for installing Windows Vista. As I was doing this I came across a Cisco folder containing more notes than I thought I had. When I get time I'll sift through them and post them in my Cisco section with the others, and add a link to them here.

In the meantime, thanks for all the nice comments and remarks I receive about my Cisco notes. If you're nearing your CCNA test I wish you the best of luck!

Windows Vista Upgrade

I finally received my Vista Home Premium upgrade DVD this morning. I got an email claiming it was being shipped earlier this month and commented on my thoughts here.

Unlike the retail versions of Vista you don't get the snazzy clear box with the rounded corner. I can't complain though, it came in a clear DVD case with a quick start guide and a new OEM Certificate of Authenticity (CoA). You may remember I bought a copy of Media Center 2005 with a Vista Upgrade voucher last year.

It also comes with a slip of paper that states the following:

Licensed Device. This Windows Vista software replaces the Microsoft Windows XP software that is eligible for the upgrade to this software. You may install and use this software only on the device on which you acquired the Windows XP software.

Reassignment to Another Device.

You may not reassign the license for this software to another device.

It also goes on to talk about transferring to a third party and support services.

This goes someway to answering some of my questions. When I get around to installing Vista I'll no doubt be adding some more posts here. I need to give my hard drives a spring clean before I can do that though ;-)

Adsense and Amazon's New Context Links Beta

I received an email from Amazon Associates yesterday explaining their contextual adverts are now out of closed beta and are now available for their associates to use (although still in beta).

I checked out the demo sites they mentioned, looked at the source HTML and logged into the Associates homepage to see what customisations were available.

All it requires is a few Javascript includes at the foot of the page and all the rendering is done client-side. Essentially any word(s) on your page can be linked to Amazon or Amazon Marketplace items, and they're all relevant!

No More Manual Links!

Hold your horses! Those of you who are Adsense publishers beware! I have been reading Adsense terms and conditions and some blog posts and I'm pretty sure you can't use Adsense and Amazon Context Links ads on the same page.

Does anyone have Google's official stance on this?

What about Amazon's terms and conditions? Do they have similar terms concerning competitor contextual ads?

At the end of the day, you can't blame Google from wanting to hold on to it's huge Adsense publisher network.

Media Center Extender - Network Congestion

Media Extenders are particularly useful for streaming video to your TV. Here in the UK the only available Media Extenders you can purchase come in the form of an Xbox 360.

I have been using my Xbox 360 to stream movies stored on my main Media Center PC to my living room over a wireless network (802.11g).

Occasionally I get a "Network Congestion" message appear in the top-right-hand corner, which comes accompanied with a small amount of picture judder/stutter. It's still highly watchable, just a little annoying. Information is available to help you improve your wireless performance; however the crux of the issue is the wireless standards. The Xbox wireless networking adapter supports the following WLAN standards 802.11a, 802.11b and 802.11g. The 802.11n standard has not been ratified by the IEEE yet, but when it comes around it will improve the throughput of data.

The Xbox 360 wireless networking adapter doesn't support any draft version of the 802.11n standard however, so we are stuck with 802.11a,b,g, unless we run an ethernet cable from the router to the Xbox, but that kind of defeats the object, doesn't it?

Microsoft recommends the following:

  • Only have 1 wireless route between your PC -> Router -> Media Extender
  • Use 802.11a standard as it works at 5GHz compared to the congested 2.4GHz channel
  • Use a router designed for Windows XP Media Center Edition

I fairly certain 802.11a is not legal in the UK, can anyone confirm this?
