How to enable JavaScript in your browser and why

Posted by jpluimers on 2017/03/02

Just in case it’s not enabled yet: How to enable JavaScript in your browser and why

It even has some html to redirect to it, which I’ve replaced with the wayback machine (and put into a gist as WordPress kills noscript tag blocks and everything they contain.


<noscript>
For full functionality of this site it is necessary to enable JavaScript.
Here are the <a href="http://web.archive.org/web/20160402005258/http://www.enable-javascript.com/&quot; target="_blank">
instructions how to enable JavaScript in your web browser</a>.
</noscript>

I needed it as at a client site, one of the embedded devices would show the message “Javascript is required to use this web portal” in various web browsers so I had to check the JavaScript status in each browser.

When your browser extensions go rouge…

Posted by jpluimers on 2016/11/21

A while ago I suspected at least one of my Chrome extensions to do funny things.

In the end it appeared that “Live HTTP Headers 1.0.8” went rogue a while ago and has by now been removed from the store as this link is gone: https://chrome.google.com/webstore/detail/iaiioopjkcekapmldfgbebdclcnpgnlo ()

It was part of a much larger set of extensions that went away and isn’t limited to Chrome: other browsers with extension mechanisms suffer from this too. More links about this at the bottom of this post.

Which means that by now you should be really careful which extensions you have installed and enabled.

So, browse through these and ensure you’ve disabled everything you don’t need permanently:

On my system, I removed these:

When you go from Chrome to these URLs through the extensions page, it usually appends an UTM tracker like utm_source to the URL.

So I dug into that as well and found these links explaining them:

Schlechte Nachrichten für Fritz!box User: http://nic.box/ Euer http://fritz.b…

[WayBack] Schlechte Nachrichten für Fritz!box User: http://nic.box/ Euer http://fritz.box ist nicht mehr das, was es sein sollte. EDIT: Muahahaha … – Kristian Köhntopp – Google+

Now there is http://nic.box/ for the new [WayBackbox top level domain and AVM does not yet have the pre-registered fritz.box there effectuated (because .box is not in final registration state yet).

Kristian:

Schlechte Nachrichten für Fritz!box User: http://nic.box/ Euer http://fritz.box ist nicht mehr das, was es sein sollte.

EDIT: Muahahaha

kris@h1755802:~> host fritz.box
fritz.box has address 127.0.53.53
fritz.box mail is handled by 10 your-dns-needs-immediate-attention.box.

The joke is in the cryptic “your-dns-needs-immediate-attention” and usage of 127.0.53.53. to indicate a gTLD name collision.

Chrome knows about ICANN though and explains it in a slightly more readable form when browsing to http://fritz.box (:

Letsencrypt and support for Google Chrome “Requiring Certificate Transparency in 2017”

Posted by jpluimers on 2016/10/29

This week there was the very important Google Chrome Announcement: Requiring Certificate Transparency in 2017 – Google Groups [Archive.is].

I’m glad that letsencrypt already submits all certificates to Certificate Transparency logs [WayBack] for X1 and X3 but there is more to it as you can read in How Certificate Transparency Works – Certificate Transparency [WayBack].

So there’s a [Google Chrome] Announcement: Requiring Certificate Transparency in 2017 – Feature Requests – Let’s Encrypt Community Support [WayBack and Archive.is].

Hopefully one or both of these issues see some progress soon:

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.

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.
