NYTProf v3 – a sneak peak

/ TimBunce / 4 Comments

I’ve had a great week at OSCON. The talks are excellent but the real value is in the relationships formed and renewed in the “hallway track”. I’m honoured and humbled to be able to call many great people my friends.

My talk on Devel::NYTProf seemed to go well. This year I covered not just NYTProf and the new features in v3 (not yet released) but also added a section on how to use NYTProf to optimize your perl code.

Here’s a quick summary, with links to the slides and screen-cast, and outline what’s still to be done before v3 gets released (getting closer by the day). Continue reading →

Hey, my own TV channel!

/ TimBunce / 6 Comments

It felt strange when I first set up this blog. What would I write about? Who would care?

For several years now I’ve been giving talks at conferences and workshops. I’d generally upload a PDF of the slides somewhere, or at least email them to anyone that asked. I’ve now added a special page on the blog where I can list all the talks I’ve given. That now acts as a single location to find all my talks and links to slides any related materials. (It’s currently a work-in progress. I’ll be filling it in from time to time. Any major updates will be accompanied by a blog post.)

Slides, no matter how good, miss much of the real event. No ad-libs, no questions and answers. When writing slides I’m always caught between the desire write little, so the audience can pay attention to what I’m saying, and to write lots, so people reading the slides later still get a reasonably full picture.

There’s also the problem of notes. I often use ‘presenter notes’ on the slides to give extra information. Both to myself, if I may need it while presenting, and also for links to data sources and credits for images used. I’ve uploaded some talks to slideshare.net but I have to include a separate version with notes (which is useful for download and print, but almost unreadable in their viewer.

I tried making a video of a talk on a camcorder. The results weren’t great. Grainy, noisy, hard to read, and massive video files.

Then I decided to try using screencasting software. I bought a great wireless USB microphone and the amazing ScreenFlow screencasting software. Now I can to capture everything in fine detail and edit it easily afterwards.

Great. Now what? I needed somewhere to host the (very large) videos. I looked around and tried a few, like vimeo, but wasn’t happy with the results. Vimo, for example, transcode to quite a low resolution and don’t let viewers download the original.

Eventually I found the wonder that is blip.tv. A whole laundry list of great features. If you produce videos of any kind, give them a look.

So, now I have my own TV channel.

Strange world!

Irish Open Source Technology Conference – June 18th-20th

/ TimBunce / 1 Comment

I’ll be speaking at the Irish Open Source Technology Conference this year. It’s on at Dublin’s CineWorld Complex, from June 18th for three days. They’re running a 2-for-1 offer on tickets at the moment.

I’ll be speaking about something Perl’ish, naturally.

The “Perl Myths” presentation I gave at IWTC earlier this year turned out to be a hit. (At least, it was after the event. There were less than ten people in the room at the time, including me! Perl clearly isn’t a hot topic among Irish web developers.)

My blog post, with embedded slides and video, has topped 7400 hits, plus another 3000 or so views on slideshare.

I’m upgrading my methods for this next talk. I’ve bought a great wireless USB microphone and the amazing
ScreenFlow screencasting software to capture everything in detail.

So I’m going all high-tech. No more “camcorder perched on a chair at the back” for me!

It’ll be a good trial run for OSCON where I’m speaking in July.

Perl Myths

/ TimBunce / 30 Comments

Update: several more recent versions of my Perl Myths talk are available. These have significant updates. Slides can be found on slideshare.net and screencasts can be found on my blip.tv channel.

I’ve uploaded my Perl Myths presentation to slideshare.net and google video:

“Perl has it’s share of myths. This presentation debunks a few popular ones with hard facts. Surprise yourself with the realities.”

While I agree with Andy Lester that Good Perl code is the best form of evangelism, I wanted to put together a presentation that others could refer to when they encounter misinformation about Perl. I cover these myths that I’ve heard recently:

  • Perl is dead
  • Perl is hard to read / test / maintain
  • Perl 6 is killing Perl 5

and pull in a wealth of upto date information, some of it quite surprising even to those familiar with Perl and its community. There are two versions, plus a video. I recommend the one with notes (which have useful extra detail and context for the slides) which is best viewed as a PDF. There’s also one without notes which I’ve embedded here:

I videoed an extended version of this presentation at IWTC in Dublin in February. The first 40 minutes or so correspond with the slides above. In the remaining 30 minutes or so I talk about Parrot and Perl 6. I’ve embedded the video below, but wordpress forces me to use a small size so you’ll probably prefer to view it at video.google.com:
