Far less active on blog on social media: some personal things that need to be done.

Posted by jpluimers on 2019/04/03

Some people already noticed me being far less active on social media including this blog.

This will continue for a while, as I am supporting two people that are very dear to me.

  • One needs to get some MRI scans very soon, with past results not being promising, so consequences not clear yet.
  • Another I am protecting from mental abuse by somebody close, something which is very hard to prove, but has very real consequences. Recognising the – initially very subtle – behavioral changes, and convincing other people up the supporting and medical tree they were indeed true and related, took several years, so I recon the recovery process will take long too.

Luckily, my blog queue has been filled with about 2 years of content, so that will run automatically.

Social media response from me will be on a “when I feel like it” base until further notice, focussing on things that give me energy and bring me joy.

The biggest lie I tell myself is not about new years resolutions.

Posted by jpluimers on 2019/01/01

The biggest lie I tell myself is “I don’t need to write that down, I’ll remember it”

It’s likely older, but the oldest reference I could find was 2012 [WayBack].

So before I forget:

Happy New Year everyone!

With the above quote, it is no coincidence I started my blog even earlier (in 2009): it’s my off-line memory, way better readable than my hand-writing and indexed by various search engines.

“ESXi 6.5” “vSphere Web Client” “VMware Tools” – how to install/upgrade

Posted by jpluimers on 2019/04/19

This got me zero good hits in the top 10: “ESXi 6.5” “vSphere Web Client” “VMware Tools” – Google Search

Since how to install/upgrade moved, here is a screenshot how to install or upgrade the VMware Tools using the “new” vSphere Web Client that standard in ESXi 6.5 and up:

It would be much more intuitive if the blue bar just linked to that action.

Postfix and blacklists

Posted by jpluimers on 2019/04/19

Still learning postfix configuration, below are some links on how to enable various blacklists that use the RBL DNS (aka [WayBack] DNSBL) way of operations.

They are centered around using the of the [WayBack] Postfix Documentation entry reject_rbl_client listings:

Basically reject_rbl_client is part of smtpd_client_restrictions.

TODO:

I need to dig further into some other blacklist options than reject_rbl_clientreject_rhsbl_client, reject_rhsbl_reverse_client, reject_rhsbl_sender or reject_rhsbl_recipient restriction.

Then I need to go through these links:

Where do you place your unit uses?

Posted by jpluimers on 2019/04/18

Over the years, I have had the question of where to put uses list entries a lot.

Last year, there was one again from a very experienced developer: [WayBack] Where do you place your unit uses? Over the years, I’ve come to preferring to place my uses in the Interface section only, even if its types, constants… – Lars Fosdal – Google+

The answer is really simple, and comes down to this:

  • use only the units you need (Law of Demeter)
  • use the units as close as possible to where you need them (this helps Minimizing Scope which is related to Information Hiding and the Proximity Principle)

Besides these Clean Code and Code Complete arguments, there is another very important argument:

The larger the scope of a unit, the more resources it takes to compile your project.

This gets worse when you have cycles in your unit dependencies.

I think it gets more than progressively worse; I have seen ~5 million line projects use close to 2 gigabytes of RAM during compilation when they had deep/long cyclic dependencies, forcing a full project build with DDevExtensions configured correctly in order to avoid out-of-memory at all.

For the above question, the poll seems to indicate the public at large gets it right:

When +Google Nederland maps only fills one or part of the map tiles…

Posted by jpluimers on 2019/04/18

I still have to do this every few weeks on all my desktop machines: [WayBack] When +Google Nederland maps only fills none or part of the map tiles… – Jeroen Wiert Pluimers – Google+

When +Google Nederland maps only fills none or part of the map tiles at https://maps.google.nl, but https://maps.google.com works fine, then remove any gsScrollPos cookies from www.google.nl.

I need to do this every couple of days to keep maps.google.nl working.

Later I also found it can happen for YouTube, then did more digging for gsScrollPos and found a better workaround: [WayBackAwesome Cookie Manager where you can just delete the gsScrollPos cookies from all sites in one go.

Even later I found out that this can be one of the causes for the WayBack machine giving an error 400 when archiving. A more common reason however is that many archived web-pages try to create cookies in the web.archive.com subdomain resulting in the same problem.

The cause seems to be the Great Suspender plugin which should be fixed by now, but might not automatically update to the latest version. See:

Pending a new Great Suspender release, below is a quick way to manually remove them if you are into SQL scripting for sqlite. It basically comes down to executing the below statement when Chrome is closed:

delete from cookies where name like 'gsScrollPos-%'
