How I Build Presentations, appendix 1: Simulate a type writer with PowerPoint

For the rest in the posts in this series please see the series index.

So the first of the appendixes of this series is an idea I had for the presentation: animate the content of the code slides so it looks like it is being typed. This never made it into the final presentation because each slide change (i.e. changing from one slide to another) causes your audience to lose focus on you a look at the screen. Animation is a powerful tool to help get your point across but you should not be just animating for wow factor, because then the audience will just watch the slides and ignore you.

Anyway for those who can find a good use of this effect, here is how to do recreate it. Note I am using PowerPoint 2010 Beta 2, but this should work in previous versions too.

Clipboard01

The above image shows what the slide looks like at the start. The white block is just a normal text block with some text in it. I have turned on the animation pane as I will need it later. First select the text block, and choose the Appear animation effect.

 Clipboard02

The animation pane will now have each line as an appear, set to show individually on click. So click one will show the white block, click two will show “static void Main()” etc… Not really what we want… yet.

Clipboard03

First I removed the first item (the Content Place Holder) as I want the white block there from the start, then I select all the remaining animations, right click, and select Effect Options…

Clipboard04

In the options dialog I change the Animate text setting from All at once to By letter and I change the delay per letter (hidden behind the drop down above) to 0.25 as that seems to be a better speed for this and finally click OK.

Clipboard05

Next, in the Animation Pane, I select from items two to the last item and right click again and change to Start After Previous which means I do not need to click for each line to appear. That is it, now you have a decent typing effect in PowerPoint.

I recorded a video of it which you can view by clicking here.

How I Build Presentations, day 6: Dry runs

For the rest in the posts in this series please see the series index.

Clipboard02 So today the visible changes to the slides are minor, the work really revolves around finishing up the demo script and minor cleanup. Today is maybe the most important day of work for a presentation as it is the day I do my first set of dry runs! Dry runs are vital because if you want to be successful you need to practise, practise and practise more.

All this practise is part of preventing the dreaded demo crash! Interestingly the stats on session scores show that demo crashes are one of the biggest causes of low speaker scores so you want to make sure you do what ever you can to prepare for them. On the right is  a tweet that Anu said about no matter how hard you plan to avoid crashes they can catch you. Now it may look unprofessional to have a crash, but in Anu’s case she shows more professionalism because she had a backup in case her demo crashed: the live bits and so she could continue with her demo.

So what do I do for my preparations to make sure my presentations look good and do not crash?

Demo bits

If you look at my previous parts in this series I have fully completed demo, a demo base, the parts I need for demo in an XML file and in the notes of my PowerPoint. All that is just for the code for my demo and so I am covered for a lot of the issues which can go wrong.

Backups

Backups are important, so all my slides and demo’s are backed up to “the cloud”, so that even if I have a serious hardware failure I can pull the bits down and get up and running.

Connections

A lot of demo’s are prepared by sitting at a desk somewhere, normally connected to the internet with a specific configuration setup. However that is seldom where you present them – normally you present them at an event where you may or may not have internet, may or may not have network (wired or wireless) connectivity or even power. Why is that important? Because the change of environment can mean a settings change that crashes demos.

Two examples of this are power and networks. Power is an interesting for laptops since the performance could be changed if the OS detects there is no power – so your demo’s or videos may run slower than expected. In fact for my demo’s I have changed the upper limit from 100 000 to 10 000 as it runs too slowly when not on power.

Network connectivity is also something to check because if you are using a virtual machine then not having network connections could mean that the network on the VM is disconnect and then you cannot connect to the services running on it.

The tip her is to check that your demo’s still work when you not at your desk.

Projectors

Projectors are very different to a monitor and doing a demo on them is MUCH different to how it is when looking at your monitor. The key differences are I want to highlight are resolution, contrast, screen mode and layout.

Resolution

Projectors seem to come out of the stone age as getting above a resolution of 1024x768 is VERY VERY difficult. For me this has been a problem in the past when it came to Visual Studio. With all it’s toolbars and chrome, the code area is so small at that resolution it made it hard to demo. Knowing this earlier means making sure you get your configuration right and your demo will better.

Tip: Alt+Shift+Enter will full screen your code or designer window in Visual Studio – very useful to get the gunk out the way. If you are using VS2010 then you can also undock and maximize the window.

Contrast

One of the worst demo’s at TechEd ever unfortunately was one of mine. I had a great demo planned – beautiful application which was styled in a white, grey and blue theme. When projected to a movie sized screen at TechEd though, the projector was not able to get enough difference between the colours. So the application just looked like a big white screen with shadows. What I had failed to do was test that demo on a projector ahead of the time, else I would have seen the issue and would have been able to fix it.

Screen Mode

When you are doing a demo at your desk you can see the screen and have control over it – when using a projector you are either in duplication mode, which gives you the same feeling or in extended mode where you have to juggle between the projector and you machine.

I once forgot to print my notes (yes, I keep a printed copy of my slide and notes, so that I have yet another fall back) before a dry run with some people. Being still new with the presentation I hadn’t memorised the demo’s which meant I needed to read my demo script on my screen and have my demo on another one. This meant connecting to the projector in extended mode. Well it was a nightmare, I struggle with the difference in resolutions, popup’s occurring on the wrong screen and neck hurt from having to look backwards and forwards the whole time. 

So when possible run in duplication mode and make sure your demo’s work well then too.

Layout

Once again when you are in front of your screen and about 30cm away you can see everything easily. However when you are looking at it projected 15m away with 20 people in front of you – where things are on the actual screen becomes important. Easy tips are to avoid the very bottom since it will likely be hidden by heads and avoid the far left and right as some projectors/screens may cut off those portions of the screen. Once again testing with a real projector helps with this scenario.

Tip: I have also started using 16:9 aspect ratio for my slide decks over the traditional 4:3 aspect ratio. This helps the layout because when a slide deck with a 16:9 aspect ratio is projected by a projector with a 4:3 aspect ratio (which most projectors are) the bottom is banded out. This is the same as when you watch a wide screen movie on a normal TV, those blank bands at the top and bottom are added to compensate. That automatically handles making sure you don’t put things too low on the physical screen.

We can rebuild him, we have the technology - Rangers Factory Ships!

I am very excited that at midnight we shipped the latest Rangers solution the VM Factory!

What is the Visual Studio 2010 and Team Foundation Server 2010 VM Factory?
The purpose of this project is to build prescriptive guidance around the virtualization of the Visual Studio 2010 and guidance for full automation of the creation of virtual machines. The goal is to help users with the installation and configuration of virtualized environments with least effort and maximum automation.

You can download it from Codeplex

What is in the package?

The download package consists of two ZIP package downloads:
  • Rangers Virtualization Guidance
    • Focused guidance on creating a Rangers base image manually and introduction of PowerShell scripts to automate many of the configuration tasks.
    • Virtualization guidance looking at the “why” and “how” to use virtualization for Team Foundation Server and Visual Studio, including planning, pre-requisite software, use of non-Microsoft virtualization technologies and introducing use case scenarios.
  • Rangers Factory Package and Guidance
    • Reference walk-through documentation on how to install, configure and support a Microsoft internal or an external factory to automate the installation of Team Foundation Server and Visual Studio environments.
    • Microsoft Deployment Toolkit metadata and PowerShell scripts used to create a Rangers factory.

The two little secrets of this is that the guidance, while targeting specific products on VM’s can actually be used as a base for non-VM scenarios and as since products like TFS use a lot of core services, for example SQL, there is a lot that can be used to build on for working with other products. The other secret is that a lot of the PowerShell scripts here are my own work, so I am very excited to see them get used and get some feedback on them!

Holy download fever Batman

Seems that in the last week, and just in time for me to be in Canada where they have bandwidth, that a bunch of things have become available for download which deserve your attention:

VS 2010 Quick Reference Guidance is now out!

Plus hotfix 1 for it

Visual Studio Team Foundation Server 2010 Upgrade Guidance is now out!

The new Nokia 5800 firmware (40.0.0.5) is out – which brings it up to the level of the X6 in features now!

Lastly, and sneakily at the end of this post, my latest open source tool is out. Now I am not going to tell you what it is, but it is for presenters (mostly) and requires .NET 4.0 Beta 2 and Windows 7. Hopefully the name will entice you to check out Rule 18!

Dev4Devs - 28 November 2009

Well today is the day! Dev4Dev’s is happening at Microsoft this morning and I will be speaking on 10 12 new features in the Visual Studio 2010 IDE. For anyone wanting the slide deck and demo application I used you can grab them below.

The slide deck is more than the 6 visible slides, there is in fact 19 slides which cover the various demos and have more information on them so you too can present this to family and friends :)

Note worthy

I have been very focused during the day on a project and my evenings have been taken up a lot with VSTS Rangers work so the blog has lagged a bit so here are some things you should be aware of (if you follow me on Twitter, then you probably have heard these in 140 characters or less):

I was awarded the title of VSTS Rangers Champion - this is a great honour since it is a peer vote from VSTS External Rangers (no Microsoft Staff) and MVP’s for involvement in the VSTS Rangers projects.

The VSTS Rangers shipped the alpha of the integration platform for TFS 2010 - this is important for me because it means some of the bits I have worked on are now public and I am expecting some feedback to get them better for beta and release next year. It is also important since my big contribution to the integration platform, which is an adapter I will cover in future blog posts, has a fairly stable base.

Dev4Dev’s in coming up in just over a week. This is one of my favourite events because it really is event for passionate developers since they have to give up a Saturday morning for it (no using an event to sneak off work). I will be presenting on Visual Studio 2010! Which should be great, based on my first dry run to an internal audience at BB&D last week. Two more of my BB&D team mates will be presenting Zayd Kara on TFS Basic and (if memory serves me) Rudi Grobler on Sketchflow!

The Information Worker user group is really blowing my mind with it’s growth, on Tuesday we had 74 people attend our meeting. For a community that only had a 100 or so people signed up on the website at the beginning of the year that is brilliant. Thanks must go to my fellow leads: Veronique, Michael, Marc, Zlatan, Hilton and Daniel. We will be having a final Jo’burg event for the year on the 2nd and it will be a fun ask the experts session.

NDepend - The field report

I received a free copy of NDepend a few months back, which was timed almost perfectly to the start of a project I was going on to. However before I get to that, what is NDepend?

NDepend is a static analysis tool, in other words it looks at your compiled .NET code and runs analysis on it. If you know the Visual Studio code analysis or FxCop then you are thinking of the right thing - except this is not design or security rules but more focused at the architecture of the code.

Right back to the field, the new project has gone through a few phases:

  • Fire fighting - There were immediate burning issues that needed to be resolved.
  • Analysis - Now that the fires are out, what caused them and how do we prevent it going forward.
  • Hand over - Getting the team who will live with the project up to speed.

Right, so how did NDepend help me? Well let’s look at each phase since it has helped differently in each phase.

Note: The screen shots here are not from the project, since that is NDA - these are from the application I am using in my upcoming Dev4Dev’s talk.

Fire Fighting

The code base has over 30000 lines of code and the key bugs were very subtle and almost impossible to duplicate. How am I supposed to understand it quick enough? Well first I ran the entire solution and I start looking at it in the Visual Explorer:

image

The first thing that it helps is dependency graph in the middle which visually shows me what depends on what, not just one level but multiple levels and so on a large project it could look like:

ComponentDependenciesDiagram

Now that may be scary to see, but you can interact with it and zoom, click and manipulate it to find out what is going on.

image

For fighting code I could sit with the customer people, and easily see where the possible impact could be coming from. So that gets it down to libraries, but what about getting it down further? Well I can use the metrics view (those black squares at the top of the image above) which I change what they mean - so maybe the bigger the square the bigger the method, class, library etc… so using the logic that at some magical point (about 200 lines - according to Code Complete by Steve McConnell), the bigger the method the more likely that there is bugs in it. I could use that to find out where to spend time looking for the problems first, which meant that the problems were found quicker and resolved.

Analysis

Right now that the fires were over moved on to analysis to make sure that it never happened again - well when a project is analysed by NDepend it produces an HTML report with the information above but also a lot of other information like this cool chart which shows how much your assemblies are used (horizontal axis) vs. how a change may effect other parts of the code (vertical axis):

AbstractnessVSInstability

And that is great to see what you should focus on in refactoring (or maybe what to avoid), but there is another part which is more powerful and that is the CQL language which is like SQL but for code so you can have queries like show me the top 10 methods which have more than 200 lines of code:

WARN IF Count > 0 IN SELECT TOP 10 METHODS WHERE NbLinesOfCode > 200 ORDER BY NbLinesOfCode DESC

Some of these are in the report, but there is loads more in the visual tool and you can even write your own. I found that I ended up writing a few to understand where some deep inheritance was getting used when it came to exception handling specifically. In the visual tool this is all interactive too, so when you run that query it lights up the dependency tree and the black squares so you can easily see what is the problem spots and identify hot spots in the code.

Hand Over

Moving the final stages, I have to get the long term guys up to speed - how do I do that in a way they can understand without going through the code line by line? Easy, just pop this on a projector and use it as your presentation tool, with a custom set of CQL’s as slides or key points to show. What makes this shine is that it is live and interactive so when taking questions or doing a discussion you can easily move to other parts and highlight those.

All Perfect Then?

No, there are some minor UI issues that are more annoyance than anything else (labels not showing correctly in the ribbon mode or the fact that you must specify a project extension), but those are easily overlooked. The big problem is that this is not something you can pick up and run with - in fact I had tried NDepend a few years back and decided it wasn’t for me very quickly. If it wasn’t for a lot more experience and having an immediate need which forced me over that steep initial learning curve then I would never have gotten how powerful it is. That also brings up another point, the curve is steep - and if you aren’t used to metrics and thinking on an architectural level then this tool will really cause your head to melt and so this is not a tool for every team member, it is a tool for the architects and senior devs in your team to use.
