The last thing you need to do when you cause link rot is to list the page as “online banking is down”

Posted by jpluimers on 2020/03/10

Nice example on how not to copy with link rot: as a bank is to indicate “internet banking is unavailable” scares your customers away.

[WayBack] Jeroen Pluimers on Twitter: “dit heet overigens link rot, en gebruiksvriendelijke sites proberen dat te voorkomen; is zeker niet gecompliceerd en eigenlijk ook niet complex: het is een kleine moeite om dat in je ontwerp en onderhoud-proces mee te nemen. 1/2 …

[WayBackJeroen Pluimers on Twitter: “de huidige down-melding zet sowieso je klanten volledig op het verkeerde been, dus daar moet zeker iets aan gebeuren. 2/2 “I.v.m. een storing kunt u geen gebruik maken van Internet Bankieren. Internet Banking is unavailable”…”

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!) 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 Any posts scheduled beyond that amount will not be published.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.


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:

So as the author of CSS3 Animate It I have a good background in CSS animation. Before CSS3 was released you would have to resort to using JS for animation…

Even after CSS3 got introduced, I’m still not sure I’d use animation: [WayBack] CSS Animation How To Tutorial – Dev Tuts

I’m harvesting credit card numbers and passwords from your site. Here’s how.

Posted by jpluimers on 2020/01/14

Below is one of the reasons I try to stay on the back-end side of things. Those are complex enough to focus on for me.

[WayBackI’m harvesting credit card numbers and passwords from your site. Here’s how.

It basically comes down to:

  • anything in the same page has access to anything happening on that page.
  • be careful when using npm and ad networks.
  • perform security operations in a light-weight iframe that is scrutinized.

The source of any npm package might be different from the source you find in a the underlying repository. This recursively holds for all the other npmit pulls in.

When LinkedIn throws HTTP result code 999 at you it means it does not like you

Posted by jpluimers on 2019/10/23

LinkedIn is very private about itself which means you have a hard time linking to their content.

Too bad, as they make themselves an island.

I sorted this out a while ago to see why the Press-This and other bookmarking functionalities in web-browsers would fail for LinkedIn:

[WayBackWordPress/press-this: Linked-In URLs do not parse correctly

@kraftbj I found the below ones on StackOverflow and a general sentiment from is “Using the invalid HTTP response 999, LinkedIn blocks vary over time depending on both UserAgent and IP address blocks including many hosting and cloud service providers”.
