Great tool: the Toptal Colorblind Web Page Filter

Posted by jpluimers on 2020/08/06

Colorblind Web Page Filter

Colorblind Web Page Filter

A great tool I found out about a while ago [Archive.is] Toptal Color Blind Filter.

It shows the original web page and the rendering for various types of color blindness:

  • protan -> Protanopia: red/green color blindness; anomalous red cones
  • deutan -> Deutanopia: red/green color blindness; anomalous green cones
  • tritan -> Tritanopia: blue/yellow color blindness; anomalous blue cones
  • grey -> Greyscale/achromatopsia: quick check for all forms of colorblindness

Because of a comment at[WayBack] Forums… https://embarcaderomonitoring.wiert.me/ – JWP – Google+, I used Toptal to notify Uptime robot that their status pages are hard for color blind people: [WayBackJeroen Pluimers on Twitter: “Some color blind people indicated to me that @uptimerobot status pages are hard for them to read. Examples are for @EmbarcaderoTech as they have subdomains being offline often: …”, so lets look at how people with various types of color blindness see embarcaderomonitoring.wiert.me :

Duh moment: when 69.162.119.78 is querying your DNS infrastructure and it appears to be uptimerobot

Posted by jpluimers on 2020/07/28

From the hindsight department [WayBack] Nice when someone in Dallas using 69.162.119.78 is querying your DNS infrastructure for many permutations of domains… https://gist.github.com/jpluimer… – Jeroen Wiert Pluimers – Google+.

Wolfgang Rupprecht gave me some hints on the cause, as the IP address 69.162.119.78 Google Search used to be of a gaming server: [WayBack] TwotailsTikat’s Profile – Member List – Minecraft Forum

After a good night sleep,

# nslookup 69.162.119.78
78.119.162.69.in-addr.arpa name = mail.uptimerobot.com

In retrospect: perfectly normal behaviour for monitoring machine “snip”.

When monitoring Windows service memory consumption from Zabbix and you get zeros

Posted by jpluimers on 2020/02/17

This is a small reminder to myself that when monitoring Windows service memory consumption from Zabbix and you get zeros, it means you need to monitor the Windows process instead of the service. The process will give you actual memory usage.

Do I really need to write a WordPress API wrapper to check the status of “missed schedule” posts?

Posted by jpluimers on 2020/01/29

After years with “missed schedule” posts on (paid!) wordpress.com based sites, WordPress has documented that the scheduler officially does not support more than 100 posts:

[WayBackWarning: Please do not schedule more than 100 posts. Any posts scheduled beyond that amount will not be published.

In practice this is not fully true, so lets explain that a little.

Background

Imagine the list of scheduled posts as a list of posts to be posted anywhere from the near future (lets call that tail) until far in the future (for now head).

As long as you schedule posts in head to tail order, then there is no problem. You can schedule 100s of posts (usually I’ve between 700 and 1200 posts scheduled that way).

The problems appear when:
