Jimmy Wales in Sofia, Bulgaria (full video)

Thursday, June 11th, 2009

On June 6th, I was lucky to listen ‘live’ to Jimmy Wales — the guy who invented Wikipedia. Jimmy (or ‘Jimbo’, as he prefers to be called himself) has a personal blog and… (of course!) a page in Wikipedia;-)

I was able to record almost everything on video, and now, finally, I’ve succeeded in encoding & uploading the files…

Here they are!

Part 1 (~35 minutes):

Part 2 (~45 minutes):

Part 3 (~20 minutes):

Now, if you’re curious, here are some notes:

1) The total length of the videos is around 100 minutes. They’re split in three parts: Part #1 (~35 minutes), Part #2 (~45 minutes), Part #3 (~20 minutes).

2) These 100 minutes of video are un-edited and show the presentation of Jimmy Wales almost in full — actually, maybe only half a minute of video is missing…

3) I have started the recoding a couple of seconds after Jimmy came to the stage of the theater and started speaking. I’ve ended it right after he left. During the recoding, I had to change the batteries (and the 8 GB SDHC card) once, just in case, which is exactly where the pause between videos #1 and #2 is. This pause was not longer than 15-20 seconds. Then, there was another pause (between videos #2 and #3), but it was less than 2 seconds. Also, during recording, I made maybe 2-3 photos, which are the cause for a couple of less-than-a-second interruptions, and that’s all. Apart from that, the video is completely un-cut.

4) The presentation of Jimmy was 40 minutes long + there were 60 additional minutes, filled with questions & answers. So, what you’re about to see is:

#1 (35 minutes): the presentation of Jimmy Wales (it continues on video #2);
#2 (45 minutes): the first 4 minutes are the end of his presentation — after that, the questions’ part begins;
#3 (20 minutes): the questions’ part continues, and then the evening is over and Jimmy is leaving.

(I am not that good with editing video, so I was unable to merge all there videos into one, but this is not that important, I hope:)

5) Original videos were in very good quality — .AVI format, 640 x 480 px, approx. 16 Mbps (video+audio streams), with stereo sound. I re-encoded them to .f4v format and brought them down to less than 2 Mbps, while the quality of the video/audio remained almost unchanged.

6) Encoding was made using Adobe Flash Media Encoder CS4: approx. 1.3-1.8 Mbps H.264 video and 128 kbps AAC2 audio. The player I am using here to embed them is JW FLV Player, which does a great work.

6) You’ll need a relatively new computer (Pentium 4 or better will do well) + high speed Internet connection, to be able to watch them normally (over 1 Mbps speed is recommended). If your Internet connection is slow (and there are interruptions), start the first video, and put in on ‘pause’ for a few minutes. This will allow the player to cache some part of the video stream and then you’ll be able to watch it normally. Then proceed the same with the other two videos.

7) The videos are not perfect — sometimes the camera may lose focus for a second or two, for example, or measure the light incorrectly. Also, note that most of the time I have focused the camera on Jimmy (and not on his slides) — in my defense I can only say that usually, if I did not shift focus to the presentation screen, then the things on the screen were simply the same things that Jimmy said, so I preferred to focus on the lecturer instead;-)

8) The License:

I am releasing these videos under CC-BY-SA license, which is one of the most liberal Creative Commons licenses. It allows you even the commercial use of the videos, as long as you mention me as their author + put link to www.optimiced.com (plus, optionally, to this particular page).

It’s also a good idea to link to the CC license I have used, and/or clearly specify that you are re-distributing them under the same conditions.

9) If you want to re-distribute the videos online:

Here are direct links to the files, which you may download and then upload to your own web server:

mvi_4143_jimmy_wales_part1.f4v (~ 362 MB)
mvi_4148_jimmy_wales_part2.f4v (~ 456 MB)
mvi_4149_jimmy_wales_part3.f4v (~ 210 MB)

After that, you’ll need some kind of FLV/F4V Flash player, to embed them in your own website.

For watching the videos offline, the excellent FLV Player will do a great job (works on Windows XP/Vista; if you are a Mac/Linux user, you’ll have to search for yourself, but I am sure you have a solution handy).

10) There is no 10! :-D …Actually, there is — please, re-tweet & re-blog the videos, as I am sure that they’ll be interesting to a lot of people! :)

I hope you will enjoy the videos, too! :-)

Jimmy Wales in Sofia, Bulgaria

Sunday, June 7th, 2009

Today (or rather, yesterday, as it is 3 am now;-) I was on a very interesting presentation by Jimmy Donal “Jimbo” Wales. For those who maybe don’t know — this is the man behind Wikipedia project, the world’s largest encyclopedia! ;-)

Jimmy Wales (wikipedia.org)

The man who invented Wikipedia, made his presentation in a fascinating way!

The presentation itself was a bit longer than half an hour, but a lot of questions ensued, so the event passed between 18:00 до and 20:00.

I was able to record almost everything on video, and I’ll try to put it online in a few hours (I hope I’ll be able to, as this is the first time that I try to encode and upload such large video files).

Stay tuned! :)

New W3C HTML icons (from Veerle)

Thursday, June 4th, 2009

Veerle just released a set of great looking HTML icons:

W3C HTML icon from Veerle, variant 1

W3C HTML icon from Veerle, variant 2

W3C HTML icon from Veerle, variant 3

W3C HTML icon from Veerle, variant 4

If you are a Mac user (and Web designer), then you maybe use the Markup Validator S.A.C. — this app is a stand-alone version of the W3C Markup Validator. The new icons from Veerle could replace the default icon of this application in your MacOS X dock.

the icons (compared)On the left you can see the current icon of the Markup Validator S.A.C. You may compare it with the variants that Veerle has made. Personally, I like her design of the icons much more! :-)

Plus, she is releasing the icon set for free to the community!

Unfortunately, the icon set is available for Mac users only. It’s a pity, because I think that these icons could be used in many more ways… Of course, you can use the JPG variants (which are high quality), but without the optional alpha transparency, which is available in the PNG format only…

If you want to use any of the icons on MacOS X, a link for download is available in the Veerle’s blog post:

http://veerle.duoh.com/blog/comments/a_new_icon_for_markup_validator_s.a.c/

(There you will also find instructions, how you can change the icon of Markup Validator S.A.C. in the dock of MacOS X.)

As to the JPG variants, you can copy them manually from Veerle’s blog, or download them as one ZIP file, which I made for my own convenience (as the icons are released for free):

download all icons in one ZIP archive, JPG format

Finally, what can I say? Another great design from Veerle! :-)

[UPDATE] Same icons, but in PNG+alpha file format. Cool! :)
