You do what at your job?

imageI tweeted yesterday that my job can be a little weird because I had to sit in the kitchen at the BBD office and watch a TV for a while. This generated some confused discussion, so what was I doing?

Our team is experimenting with the idea of putting screens around the company to share content and information and I had to sit in the kitchen to make sure it worked by watching loop the content for a bit Smile


This is also a great opportunity to share some learning's from this with you:

TightVNC is still the best VNC option

Remote Desktop from Microsoft is THE best way to remote onto another machine but it has one downside, it locks other user out. For out screen we can’t have the login shown, and I don’t even know where it is to login manually – we need to see the content on the machine so we dropped to an older technology: VNC.

There is a lot of options in the VNC space, but ended on TightVNC as it actually runs as a service on a Windows 7 machine where other VNC clients run in the user space.

Auto Login to Windows

The login screen is also an issue with the machine when it boots and I don’t want to remote in every time to login – so we configured Windows to auto login to a specific account. This is thanks to the folks at Channel9 in particular Sarah Perez & Bradley Ward:

  1. Change the following registry key to 1: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\AutoAdminLogon
  2. This enables the feature to be surfaced in Windows.
  3. Then run the following command: control userpasswords2
  4. In this UI you can UNTICK the option Users must enter a user name and password to use this computer and click OK
  5. It will then prompt you for the username & password to use and done! Note this is a bad security and so not recommended, but sometimes it is needed.

Open & Play slideshow

We are using Microsoft PowerPoint for the content and needed to auto run a slideshow at login, so we created a shortcut to run PowerPoint with the /S switch (see this for info on switches) and the filename: PowerPnt.exe /S c:\demo.pptx

That opens PowerPoint and starts the presentation!

Insert web content into PowerPoint

Lastly we wanted include some live web pages in it, which PowerPoint doesn’t support out of the box. MVP’s to the rescue! Some MVP’s created an add-in that allows it: http://skp.mvps.org/liveweb.htm

Really awesome!

Convert VirtualBox (vmi) to real disk?

It is often the case I need to setup training machines and a sometimes I get VirtualBox images which I need to deploy to the machines. I tend to avoid virtualisation on the training machines because of driver related issues, especially with graphic cards and things like WPF (which powers Visual Studio). If you have a good graphics card & good drivers then you can get a decent perf improvement with WPF apps, but unfortunately some virtualisation drivers are too poor.

So how can I take an virtual hard disk created in VirtualBox and easily convert it to physical disk so it can just run?


It is possible but it is not easy to a real disk but it is not easy.

  • Step 1: You need to use a tool from Microsoft called SysPrep to unload the drivers. Basically this means that it strips all the driver info out, and puts the image in a clean state so that the next time it boots Windows searches for the hardware again. If you do not do that Windows will freak out because the hardware it expects does not exist.
  • Step 2: Then you use a tool designed for disk imaging to create an image. Tools like Norton Ghost (paid) or CloneZilla (free) are designed for this purpose and the image they create is portable unlike the vmi (VirtualBox hard drive) format which can't do this well.
  • Step 3: You then restore that image to the real disk using the same tool and you are done.

Slightly more work than you would expect, but that is a solution which always works.


I have not tried this with Hyper-V or VirtualPC disks (vhd) yet, but I suspect VirtualPC will work fine. Hyper-V has an additional Hypervisor layer and I suspect that SysPrep will not remove that and the restoring process will fail.

Finally you also want to be careful with SysPrep as it can have some undesired effects with certain software, for example SQL Server. There are specific steps to go through if you want to use SysPrep & SQL Server: http://msdn.microsoft.com/en-us/library/ee210754.aspx

So make the time to have the first few attempts fail and learn the nuances of the software you work with.

It's official: Pepper uses Azure

Bruce Kyle, a Microsoft evangelist, wrote an article recently about the “Powered By Microsoft Windows Azure” logo and how you can earn the right to display that.

That may sound odd to some people – why can’t you say you use Azure if you do? Of course you can, but if you jump a few hoops with Microsoft you can use the official logo Smile 


But that is not all! Doing this also helps towards an ISV competence with Microsoft which gets you great assistance and free software from Microsoft, the opportunity to get $250 for marketing and also some other pieces of useful tidbits. One of those tidbits is a press release template, which is so odd for me too see as I am not in marketing, press or anyone else who does those – so lower down you can find mine Winking smile

So about those hoops, you maybe wondering how hard or easy this is? I took Pepper through the testing for both SQL Azure & Windows Azure and it took about 30min, reading Bruce’s article & watching a video. It is RIDICULOUSLY easy to do once you have your application built – SO GO. DO IT. BE POWERED BY WINDOWS AZURE!

Enjoy reading my first press release Smile with tongue out

Social everywhere doesn't work




Not being on a social network is like having a company which doesn’t appear in your favourite search engine - it is just a requirement of being online in our era and for a long time I have tried to get to the utopian world of an integrated social experience where everyone was everywhere and my updates, posts, pictures etc… trickled across all social networks, so no matter what you did you could hear what I had to say or was doing etc…

This was a stupid idea and I thought I would share my learning’s about that process.

Problem 1 – He with the most friends wins

With Facebook I feel into the trap of accepting every friend request, loading my address book into it and basically any other “tricks” I could to increase my friend count. This meant that logging on to Facebook was a stream of conscience from people I really didn’t care about and so overtime I moved away from Facebook as the value I took out of it was low.

The solution to this was to create a set of guides for people to be my friends on Facebook. I am not going to cover all of them, I’ll just focus on two of them but I had about 5 or 6 which I use to decide who to keep or accept requests from:

  1. Time span rule – if I have seen you or had more than a Christmas email for 5 years or more, you are out.
  2. Override – I can keep anyone for any reason breaking any other rule Winking smile 

Using my rule set I trimmed from over 300 friends to less than 90 and Facebook is now a daily visit site because I do care about the thoughts of those 90 people.

Summary: Be very selective of who you follow on your social networks.

Problem 2 – The right tool for the the right job

110772_strip_sundayOne of the problems with Facebook friends, is that many of the those people were “frendors” or people who I just saw in the passages at work. Facebook isn’t meant for great communication around work however there is better choices for them:

  • LinkedIn – This is great for business partners, frendors, business contacts and key direct co-workers. This ensures that the value of the conversation is higher because it is more business focused and people do care deeply about their careers on there.
  • Yammer – This is for people I work with, regardless of anything else. This is also great because it is a walled garden so we can have those private conversations that are company/team specific.
  • Twitter – We met at an event, you want to hear from me or want me to hear from you but we don’t care about much else Twitter makes a great place to put people while I evaluate their value and should I try and add them to other networks. Many people start off here and move to the others.

Sure there are a few people who are on more than one network, but those are exceptions to the rule. Most people end up in one place.

Summary: Facebook for friends & family, LinkedIn for your professional career, Yammer for co-workers & Twitter for all else.

Problem 3 – Auto post is not your friend

I personally spend more time in Twitter than any other network, and I eventually had it setup that every tweet went to Facebook & LinkedIn too. The problem is Twitter is really unfiltered and I do post a lot of jokes or half baked ideas which detract from my professional value on LinkedIn or are so technical that my friends & family on Facebook scratched their heads with confusion.

Thankfully this can be fixed: Don’t auto post. LinkedIn supports this with a setting you must enable, Yammer does this by default and for Facebook don’t use the standard Twitter app rather use the Selective Tweets app. All these require you tag a tweet with a special tag, for it to auto post, i.e. Facebook it is #fb, Yammer is #yam & LinkedIn is #li

So if I post something on Twitter and want it on Yammer & LinkedIn I append the tags and it is on all three networks but not on Facebook!

Summary: Post selectively to the right social networks.

Introducing BBD

BDDAny day I open my email and see an email from Peter Searle (the BIG boss at BBD, where I work) in there, I wonder if a trip to HR is in my near future Winking smile, today though is something far more awesome and rather that tell you myself I thought I would share Peter’s words because it is just fantastic:

More than 25 years ago Barone, Budge and Dominick, also known as BB&D, was begun by a group of people dedicated to delivering software solutions to clients. Initially, the work was done in an attic, and those people were Sandra Barone, Tom Budge and Ralf Dominick. 

The current corporate identity was created in the eighties with the founding of the company.

BB&D now employs more than 400 software professionals. We are South Africa’s largest independent custom software development company, and we serve customers in both South Africa and internationally.

In moving forward, we will never forget where we’ve come from. On the contrary, we will even further imprint the attitudes and values that have made BB&D what it is today.

We are taking the core values, achievements and expectations that have become so entrenched into the company’s make-up and are transitioning them into a fresh new identity that resonates with the next generation of the new BBD.

We are now BBD. And our brand line is – combined intelligence.

BBD work together with our clients, sharing knowledge and ensuring we can deliver solutions that improve their business.  This meeting of minds, connecting and building on each other’s brilliance enables us to design solutions for them that mark the way forward.

In essence, we are more than the simple sum of our parts. Our combined intelligence is the greater whole.

Very proud to be a BBDer Smile

Lions Rugby starting to get it right

Super-14-lions-logoLittle off the usual but as a fan of the Lions Rugby team I thought I would share this great news. One of the biggest complaints people have with Lions Rugby is going to Ellis Park for the game, once there it is great but driving through some of the worst parts of Johannesburg is a major put off and then there is the serious lack of parking.

Well it seems they have taken that to heart and have not only four dedicated parking areas they have also arranged a park & ride facility! This should hopefully bring in the fans.

Official Press Release:

StackExchange Flair

For a while the flair on my site has included my stats from StackOverflow, ServerFault and SuperUser. In my article on it, I mentioned I used the iFrame but I stopped that a few months ago and switched to getting the JSON data for my accounts directly and parsing that. I did this as it was order of magnitudes faster than loading via the iFrame.

For those who attended my DevDays talks, they would recognise that code as it is the same as I used in my demos.

Then recently an email arrived:


Damn, my jQuery magic was about to end so what could I do but change? When I started looking at the new flair I noted that StackOverflow wanted me to hotlink the image, i.e. have my visitors get it from their server, but the performance for pulling the image was still poor compared to my own website (or so the Firebug tool says). So what could I do to improve this? 

What I did was to use wget, which is a Linux tool (I’m hosted on a Linux box) for downloading files, and put that in a schedule to once a day download my StackExchange flair and store it on my website, which means it gets served faster. As my numbers won’t change heavily day to day, (I’m not Skeet) once a day is enough balance between keeping it fresh and making it cachable.

The only downside is that my flair uage stats on StackExchange will likely drop, but I don’t really care about that.

The wget command is:
