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.

Why I dislike GoToWebinar by Citrix: 0 stars out of 5.

Posted by jpluimers on 2014/10/31

Last week, I viewed to webinars. A smaller one Geek Fest – Automating the ForgeRock Platform Installation about Ansible installation of Unix machines, and the first 70% of the last day ofCodeRage 9 | Free Development Event by Embarcadero.

Both had a bad experience because of GoToWebinar has a really bad user experience.

  1.  When a GoToWebinar connection terminates, the GoToWebinar client closes. You loose everything in the Q&A log. You need to hope someone else saved the Q&A log so you can see the public questions, but the private comments you made are gone.
  2. It is impossible to install the Windows client when you are behind a McAfee Web Gateway that filters downloads and HTTPS traffic. After trying for about 15 minutes, we gave up and reverted back to a Mac over another connection. It meant we could not use the conference room and had to cram many people behind a small MacBook screen.
  3. The Mac OS X client does not allow you to resise the Q&A log, so even on a 4k display, you can see like 10 lines of Q&A.
  4. When there are many attendees, the refresh rate slows down from sub second to once per 5-10 seconds, this is really bad when watching demos of software: a big aim of webinars.

When terminating, the only thing GoToWebinar allows you to do is give feed back (too bad they don’t allow for detailed feed back). So I gave it 0 out of 5 stars.

PS: I could save the below Q&A logs. If you have other logs, please let me know so I can publish them. I’m especially interested in Have You Embraced Your Inner Software Plumber Yet? by David Schwartz – The Tool Wiz

These are the  CodeRage 9 – Object Pascal Sessions I could save the Q&A log of:

A url or site like example.org which always produces a 404 error (and two for 200 and 204)

Posted by jpluimers on 2014/09/10

Yesterday I posted this question on StackOverflow and G+: Is there a url or site like example.org which always produces a 404 error?

Soon after that, I found out three links that produce predictable HTTP status codes:

They also work for https:

Edit 20241223: these also return a 404: http://www.google.com/undefined and https://www.google.com/undefined

On StackOverflow very few people even noticed the question, probably wondering “why?”.

I’m using these links for positive and negative testing of some http / https handling code that needs to be good at coping with positive and negative responses.

In my testing life, I’ve learned the hard way that both negative and positive tests are core part of your suite, hence the question.

When http:://Feedly.com doesn’t start with any more: start it through https://Feedly.com (via: @feedly your news. delivered.)

Posted by jpluimers on 2014/03/16

Recently when starting Feedly through http://feedly.com, I got this message in Chrome on my Retina MacBook Pro:

Is feedly blocked?

Feedly is not able to load. It is probably because one of your extensions is blocking it. If you run Adblock, HTTPSEverywhere, Awesome screenshot etc.. please make sure that feedly.com is white listed.

Ask a question

I paused AdBlock: same thing. I don’t use HTTPSEverywhere or the other tools mentioned.

Solution: start using https://feedly.com. Since I prefer https anyway, I can live with that (: Read the rest of this entry »

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.

▶ 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.

30 april 1993: the free and open WWW started…

Posted by jpluimers on 2013/05/03

This year, the Dutch Queens day this year had a special nature. On the nation level: the abdication by former Queen, now Princess Beatrix, and the succession and inauguration of King Willem-Alexander. On the marching band level: Adest Musica had their Dutch premiere of the new show Mother Earth which will be their entry during the quadrennial Word Music Concours this summer. On the personal level, my best friend visiting The Netherlands for just a few days, so finally a chance to catch up in person.

So I totally missed another important historic event: the 20th birthday of the releasing the WWW source code in the public domain.

On the 30st of April 1993, CERN: Read the rest of this entry »

Google Chrome funny error message: trueAre you sure you want to leave this page?

Posted by jpluimers on 2013/02/21

Got a nice error message from Google Chrome today and wonder what the “true” means (:

true

The text is this:

[Confirm Navigation]

true

Are you sure you want to leave this page?

[Leave this Page]    [Stay on this page]

You can use Ctrl-C to copy, then you get the text below:

trueAre you sure you want to leave this page

That means it is not a standard Windows MessageBox, as pressing Ctrl-C there would copy the title and buttons as well.

Zero day vulnerability in mshtml.dll used by Internet Explorer 6, 7, 8 and 9, and many other products.

Posted by jpluimers on 2012/09/20

Summary:

  • Zero day vulnerability in mshtml.dll used by Internet Explorer 6, 7, 8 and 9, and many other products.
  • Resolution: Deploy EMET or stop using IE and other products using mshtml.dll until Microsoft delivers a patch.

Earlier this week a zero-day vulnerability in the mshtml.dll was made public. This DLL is used by almost all Internet Explorer versions (6-9 are vulnerable) and many other software products (almost anything from Microsoft and a lot of 3rd party software that displays a web page on Windows).

While Microsoft is building a fix that is to be released very soon now (probably tomorrow, Friday September 21st 2010), the official resolutions are not to use the mshtml.dll at all (impractical for many people), or deploy EMET (impractical too as it requires administrative privileges).

If you can, switch to a browser that uses a different layout engine than mshtml.dll (for instance browsers based on WebKit will do).

These pages are good starting points for more information:
