Video is too slow. Would you share your slides with us?

Why don't you use programs which increase the playback speed? You can still understand most videos if you double the speed. Saves a lot of time!

I did spend 25 minutes watching this video at 2x and I think it was a poor decision compared to reading the slides in 5 or 10 minutes.

Also, it's a big hassle to download videos from youtube, because youtube doesn't want you to do it and plays cat and mouse games. I used youtube's own beta html5 player, which lets me do 2x playback (in mac/safari, but not in mac/chrome wtf). But youtube throttles download speed to normal playback speed, so I had to wait 25 minutes before watching. (Other ways of getting videos do not throttle speed, but back when I downloaded them as files, I usually couldn't get them fast.)

You're right, reading the slides is probably enough for this video but I guess there are some videos which you want to (or have to) watch but are too slow.

I myself use MySpeed. It costs 29$ but you don't have to download the video and can change the playback speed from 0.3 to 3.0. There are probably equivalent programs for free, but my google-fu wasn't strong enough to find them.

You can use mplayer or vlc to stream youtube videos and they have the ability to change playback speed.

Anywhere on LW I can upload PowerPoint files?

The file is gone now. Please re-upload it?

BTW, the LW Wiki has an upload function, but someone needs to change the configurations to allow PowerPoint file type (and perhaps PDF while they're at it).

I'm feeling great about turning on PDF uploads, but allowing PPT uploads includes the ability to upload Office macro malware.

Do we want to allow random people to sign up for accounts then upload potentially malware bearing files?

Please do! This feature could have been (and could) be useful for me at times.

I don't think PPTs are much more dangerous than PDFs since PowerPoint disables macros by default, and PDFs can contain malware as well (that exploit unpatched holes in Acrobat software). And people who want to spread malware can always upload those files elsewhere and then link to them in the wiki or comments.

I put the file back, and contacted Matt (TrikeApps) about the upload function, which I didn't know existed.

Alas, this feature hasn't been implemented yet, but if you email me the file I will host it and link it from here.

Dropbox is good for this.
