Posted by jpluimers on 2015/02/06

Besides the cache empty instructions, these keyboard shortcut to get to the settings in various browsers are also really helpful:

  • Control+Shift+Delete on a PC, or
  • Shift+Command+Delete on a Mac.

Instantly save a web-page to the Wayback Machine (Internet Archive: www.archive.org)

Posted by jpluimers on 2014/11/24

Saving a web page for posterity is really easy: just prepend http://liveweb.archive.org/ in front of the URL in your browser, then open the page.

The Wayback Machine (Internet Aarchive) wil instantly archive it.

See this great answer by Jeff Atwood quite a while ago:

One thing that the ineffable Jason Scott just pointed out to me on Twitter:

if you give the url of the page to http://liveweb.archive.org and wait five minutes, it will archive that page. How about that?

Also you can enter http://liveweb.archive.org/http://www.website.com/page to have it happen without visiting the page.

So if you want to ensure that a popular soon-to-be or may-possibly-be deleted question gets archived by the Internet Archive, manually feed them to the URL above.

I suppose for already deleted questions, we could also undelete, wait 5 minutes, let it archive, then re-delete.

Speedup Youtube Playback: Watch Lectures In Half The Time with YouTube’s HTML5 Player

Posted by jpluimers on 2013/09/13

I wish I had kept an eye on it after it was announced (which was 3.5 years ago, but not very stable): The Youtube HTML5 viewer trial.

It has come a long way since thenFull screen it is still not as good as the official one, but the main attraction introduced since is: configurable playback speed!

Yes, you can choose playback at 25%, 50%, 100%, 150% or 200% of the original speed. Ideal for lectures or watching replays of conference sessions.

Quote from the life hacker post LifeHacker on this:

▶ How to pair a desktop or laptop to youtube.com/pair (via: YouTube; uses Opera Mobile Emulator)

Posted by jpluimers on 2013/08/04

Trick via: ▶ How to pair a desktop or laptop to youtube.com/pair – YouTube.

This trick uses the Opera Mobile Emulator.

Note that not all settings work. The Asus Nexus 7 emulator worked, but custom didn’t always work (that would open m.youtube.com as www.youtube.com/?nomobile=1 hence switching off the mobile client).

When following the steps at Pair your mobile device to your TV – YouTube Help, you are directed to m.youtube.com/select_site to select your TV and enter a pairing code.

Usually you need to retry playing a video a few times: my Philips 42PFI7676H-12 didn’t always work at first (maybe playing back streamed video inside the emulator is not supported, but telling Youtube to pass the play request to your TV is), whereas with my Google Nexus 4 it always works.

You can even pair one computer to another: on the computer that emulates the TV, browse to www.youtube.com/leanback.

Maximum URL lengths

Posted by jpluimers on 2010/04/20

A client recently asked me what space should reserve to store URLs in their DBMS.

The plurality in the topic title is a hint: different systems have different limits on URL lengths.

But first:

Don’t use long URLs

If you use long URL’s (longer than say a coupe of 100 characters), then usually you have a problem.

First of all: short URL’s are easier to remember, index and search.

Second: long URL’s can pose problems.
It might be that your browser and server support them.
But a user might be behind an intercepting proxy (sometimes invisible to both you and your user) that imposes a URL limit.

In stead of long URLs with a HTTP GET, use shorter URLs with a HTTP POST. Read the rest of this entry »
