Finding a balance between an effective presentation and “death by PowerPoint”

If, like me, you attend a large number of presentations from suppliers and partners, you are probably acquainted with the concept of “death by PowerPoint” but more recently I’ve noticed a trend towards using alternative visual aids (or even none at all) to grab the attention of the audience.

A few weeks back, Microsoft’s Steve Lamb was planning to give a full day seminar with no PowerPoint slides. I don’t know how that went (probably quite well, as it was a technical event with lots of demonstrations) but I recently saw CA’s Executive Vice President for Technology Strategy and Chief Technology Officer, Mark Barrenechea, speak without PowerPoint and I found the event to be very disappointing. Far from inspiring the audience with his presentation, the lasting impression with which I left the impressive Ditton Manor venue was one of a poorly-prepared presenter who scribbled some unintelligible notes on a few OHP foils (remember them?) and ran out of time. I’m sure that Mark was actually extremely well prepared, but that was the impression with which I left the event (and that will stick in my mind).

Whilst dropping PowerPoint is a commendable idea, in order to dump the visual aids (in whatever form – PowerPoint, OHP foils, or flipchart), an extremely charismatic presenter is required who can hold the audience’s attention completely and, in the business world, there aren’t too many people who can carry that off well.

I’m sure there is a balance to be struck somewhere between PowerPoint overload and completely disregarding any pre-prepared visual aids. Personally, I find that a slide deck can be a useful aide memoire when presenting – maybe that’s what it should be (too many people try to cram too much information onto each slide).

Having said that the slide deck should just be an aide memoire, when attending events, I like to be given a copy on which to take notes. Having to wait a few days (or even weeks) to download the slide deck after the event doesn’t work for me, but by the same token, I rarely give out my slide deck in advance if I’m using PowerPoint at an internal meeting (because I find that a small audience of customers or management tend to jump ahead and read the slide deck rather than listen to the message I’m trying to present).

Today, I’m at an event with a difference. In common with many Microsoft technical events, today’s event includes a lot of demonstrations; however instead of the usual slide with the word “demo” emblazened across it, around which I’m normally madly scribbling notes, John Craddock and Sally Storey from Kimberry Associates have included slides called “doodles”. These doodles are one-slide summaries of the key points from the demonstration, which are not presented but which allow attendees to concentrate on watching the demonstration instead of writing notes. I’ll certainly give the concept a try next time I demonstrate a technology to an audience.

Using RIS to PXE boot non-Windows images

I’ve written a few posts previously for this blog about Microsoft Remote Installation Services (RIS), but today I needed to do something I knew was possible in theory but had never done before – using RIS to serve a boot image of something that’s not an unattended Windows setup.

Although slightly complicated by the need to use Active Directory for security, RIS is, at its most basic, a PXE server, capable of serving boot images via TFTP to suitable client PCs (before an operating system is loaded). In theory, any bootable floppy can be converted into a RIS boot image file but Microsoft doesn’t provide the tools – for that you will need the 3Com RIS Menu Editor (RISME). The original version of this is a free download from 3Com – later versions (e.g. emBoot RIS Menu Editor 2.0) are available for a small price (with a free trial period) but I found the 3Com version to be perfectly adequate (although it only runs locally on a Windows 2000 RIS server, whereas v2.0 of the emBoot product allows remote creation and editing of RIS menus and boot images, and supports Windows Server 2003).

After running RISME to capture an image from boot media, an additional folder structure will have been created on the RIS server, either in \\servername\RemInst\Setup\English\Images\3com\i386\ or in \\servername\RemInst\Setup\English\Tools\3com\i386\, depending on whether or not the image was created via the Automatic Setup or the Maintenance and Troubleshooting tabs.

Along with the image (.IMG) file (which can be edited directly using a utility such as WinImage), is an appropriate boot loader (.LDR) file and a RIS setup information (.SIF) file containing something similar to the following text:

[OSChooser]
Description = "description"
Help = "helptext"
LaunchFile = "Setup\English\Images\3Com\i386\tool1.ldr"
Version = "1.00"
ImageType=Flat

RIS should automatically pick up the new .SIF file and offer it as a menu choice in the OS Choices menu although it may be necessary to edit the User Configuration | Remote Installation Services | Choice Options within the Default Domain Policy group policy object in Active Directory to allow access to some of the RIS menus (e.g. Maintenance and Troubleshooting).

I now plan to use this method to deploy Ghost images (via an MS-DOS boot disk, captured as an image) and a PXE boot to a RIS server but for more information (including links to enable PXE booting of Linux), check out Google’s cached version of an article on how to use RIS to bootstrap other operating systems (unfortunately the original is no longer available online).

My iPod has died

Just over six months ago, I bought an iPod Mini (then a few months later I started lusting for the new iPod Nano). Well, today my iPod Mini died. I was driving home when I got a call on my mobile phone. I pressed the iPod’s pause button, took the call on my phone, and when I went back to the iPod the screen was blank and I couldn’t turn it back on. I thought maybe the battery was dead (it shouldn’t have been as I charged it last night and had only used it for about 2 and a half hours) but when I got home I found that it doesn’t respond to power either. I’ve tried resetting (turn hold on, turn hold off, then hold the play and menu buttons together), but all to no avail.

At least it’s still under warranty but for any consumer electronic item to die after six months of use is not good. Grrrr…

How to make Outlook the default e-mail program

Today, I finally got around to rebuilding the notebook PC that I use for e-mail, blogging, web site maintenance and general home IT (I keep all my digital media work on another, desktop, PC). I’m taking this opportunity to try out Mozilla Firefox 1.5 (released yesterday) and to give the Mozilla Thunderbird e-mail client a go (of course, Internet Explorer is still installed for the badly-written sites that mandate its use, or that don’t recognise Firefox as a valid browser). As a long time (8-year) Outlook user, I needed to import my previous contacts (I took the opportunity to leave behind my e-mail) but this is where I’ve found Thunderbird slightly lacking…

Although Thunderbird does support the import of address book entries from Eudora, Outlook, Outlook Express and a variety of file formats there doesn’t seem to be any capacity to filter imports (or to import directly from a personal folder (.PST) file. Instead, the import relies on Outlook being the default e-mail client (or the use of an intermediate file).

The Set Program Access and Defaults feature within Windows XP (mandated as part of one of the many Microsoft antitrust rulings) that is intended to make it easier to specify the default programs for certain operations (such as web browsing, e-mail, media playback, instant messaging and choosing a Java virtual machine); unfortunately it didn’t allow me to specify Microsoft Outlook as the default e-mail client (nor did the option which is supposed to allow this from within Outlook). Strangely, what was needed was to open Internet Explorer and select Internet Options from the Tools menu before using the Internet programs drop-down lists on the Programs page.

Following this, I managed to import my data, but now I notice that my contacts’ addresses have been duplicated in both the home and work address fields. Thunderbird may well turn out to be an excellent e-mail client but its data import capabilities seem to leave a lot to be desired.

Geotagging websites

A couple of weeks back, a little GeoURL icon was added the side panel of this blog (underneath the feedmap). GeoURLs are a way of encoding location information within a website.

For example, whilst I try to make the information on markwilson.co.uk applicable to a wider audience, inevitably some of it is UK-specific. Geolocation by IP address can help to match users with localised content, but it does have some issues. A DNS lookup on markwilson.co.uk tells me that it is an alias for hp.force9.net (212.159.8.1). Using the CAIDA Internet geographic database (NetGeo) to look up 212.199.8.1 tells me that this address is actually allocated to Force 9 Internet in Sheffield, UK (latitude 53.38, longitude -1.50) but that’s not much help for localising services as that’s where my ISP is registered (it may not even be the location of their servers) and I’m nowhere near there. In addition, the CAIDA database is also no longer maintained, so other tools may be more appropriate, but of far more interest is the location to which the site’s information applies.

For locating an Internet site or service (such as a location-specific web page or RSS feed), geolocation using geotags is probably more applicable. For markwilson.co.uk, the actual code which identifies the geoURL (the geo-structure tag or geotag) is found in the HTML head and reads:

<meta name="geo.position" content="52.1542;-0.7122" />
<meta name="geo.region" content="GB" />
<meta name="geo.placename" content="Olney" />

These geotags can be generated using the geotag generator (I found out the latitude and longitude using multimap). It’s also possible to use an ICBM tag such as <meta name="ICBM" content="52.1542, -0.7122" /> but geo-structure tags are newer and also include region (using the ISO-3166-1 country names and region names specifications) and placename information.

GeoURL is a location-to-URL reverse directory (although at the time of writing it only lists 211,991 sites). A GeoURL lookup on markwilson.co.uk returns a list of sites located nearby and although it’s of limited use at the moment, as more and more sites are geotagged, information like this will become more and more relevant, particularly when combined with services such as Google Maps.

Free to air digital TV from Sky

In common with a fair proportion of the UK population, I can’t receive digital terrestrial television (Freeview) without investing in an aerial upgrade (as well buying a set-top box) – or at least that’s the way it seemed until I found that there is another, less well known, method to get free digital TV in the UK.

Toffa told me about getting free-to-air digital TV from Sky, who offer a freesat viewing card, plus digibox and dish for £150 (or, from deep within their questions and answers page, it seems that if you already have digital satellite equipment, all that is needed to get access to the free channels available on the digital satellite platform is a freesat viewing card which costs just £20 – although though some dealers are sell these cards online for significantly more money). After a bit more research, I found that many of the free digital channels are available from Sky without any viewing card – all that is needed is a Sky digibox and a dish.

When we moved into our house, we inherited a Sky minidish which had been installed by the previous occupants. It’s been unused for the last 3-and-a-bit years but after spending a few quid on a nice slim digibox (I bought a second-hand Sony VTX-S760U and Sky remote control on eBay) I can now get 78 free to air TV channels (plus radio) for free and if I do buy a viewing card, then I can add Sky Three, Channel 4 and Five to this list.

Some of the popular free-to-air digital TV channels

So there you go, if you are one of the 27% of UK citizens who can’t receive Freeview, the chances are that you can still get free-to-air digital TV from Sky (who quote 98% coverage) without a monthly Sky subscription.

Is someone trying to hijack my domain?

As you are reading this blog, you can see that I own the markwilson.co.uk domain. I also own markwilson.me.uk (even though the address details are out of date) but evidently someone out there thinks that they do and it’s getting kind of frustrating because I’m getting e-mails from people trying to get in touch with someone who is obviously giving out their address using my domain name!

So far I’ve had a quote for web design services (or is that a hint?!) and information about some conference (initially a declined credit card and then details for joining the event).

Because I try to be a good ‘net citizen, I advise people that they are using the wrong e-mail address (and most will update their records, or pick up the phone and call the guy – I can’t because I don’t have his details) but this is getting annoying now… could this be a bizarre method of generating spam in my mailbox?

If you think your e-mail address ends with @markwilson.me.uk, then I’m sorry but it doesn’t! Likewise if you’ve paid someone for that domain name, you’ve been a victim of fraud…

When mapping software doesn’t quite get it right…

I heard about this whilst watching the BBC Top Gear motoring programme last night and had to give it a go… The RAC‘s route planner on their website is a great tool, but try entering a route from Nottingham to Bideford, avoiding motorways, and the system will return a 1070.9 mile (1723.4km), 42 hour and 24 minute route via Ireland and France (at least until Map24 patch their software)!

Strangely enough, if you enter the same route using the Map24 site it doesn’t seem to get lost in this way.
