ÜberPDF printing using a Delphi like canvas

pandoc oneliner from reStructuredText to html

Posted by jpluimers on 2016/05/12

[WayBack] Pandoc is so versatile that you sometimes forget a conversion can be as simple as a one-liner:

pandoc -s README.rst -o readme.html

This converts the reStructured text in README.rst to html.

Pandoc is smart enough to recognise the conversions without you telling the formats with -f (input format) and -t (output format) explicitly.

If you do need to explicitly specify the format, it is useful to query which formats are supported as per [WayBack] Pandoc – Pandoc User’s Guide: specifying formats:

  • pandoc --list-input-formats
  • pandoc --list-output-formats

Mac: Google Chrome Helper excessive CPU usage

Posted by jpluimers on 2016/01/29

I’m not the only one with a Mac having issues with Google Chrome Helper CPU usage, but most of the entries are for older Chrome versions. So below are the steps I performed. There are also pros and cons are after the steps.

In chrome://settings/content, under “Plugins”, I ticked “Let me choose when to run plugin content” (it was at “Detect and run important plugin content (recommended)”. That dialog doesn’t allow you to copy it’s content, so no HTML, just this screenshot:

In chrome://plugins/ I disabled this one:

Adobe Flash Player – Version: (Disabled)

Shockwave Flash 20.0 r0
Name: Shockwave Flash
Description: Shockwave Flash 20.0 r0
Location: /Users/jeroenp/Library/Application Support/Google/Chrome/PepperFlash/
Type: PPAPI (out-of-process)
MIME types:
MIME type Description File extensions
application/x-shockwave-flash Shockwave Flash
application/futuresplash Shockwave Flash
Enable Always allowed to run

Pros of these settings:

  • If you have a lot of tabs open (many of them suspended using The Great Suspender), then Google Chrome Helper uses far less CPU.
  • Youtube doesn’t use the Flash Player any more. It now uses HTML5 which seems far more battery friendly and more responsive.

Cons of these settings:

De @SVB_PGB foutmelding mag kennelijk ook niet langer dan 60 karakters zijn… #neuland

Posted by jpluimers on 2015/12/21

Briljante foutmelding: “snaam, inclusief extensie, mag maximaal 60 tekens lang zijn.”

Ja: precies de laatste 60 karakters van de foutmelding.

De SVB heeft iets met 60.

Iets als “20141119 – Martijn – Zorgkantoor – AWBZ beoordeling zorgbeschrijvingen zorgovereenkomsten – SVB trekkingsrecht.pdf” mag dus niet als bestandsnaam. Een duidelijke foutmelding ook niet. Dat zou te makkelijk zijn.

Het is op een andere manier slecht dan de foutmelding “Er is een algemene fout opgetreden. Probeert u het later nog eens.”. En dat je later weer dezelfde foutmelding krijgt zodat je on-line geen PGB declaraties van urenbriefjes kunt indienen:

Beste @SVB_PGB: de online declaratie PGB WMO HH gaat fout bij het klikken van “Bewerken”: het maakt niet uit welke maand en week. 1/2

De melding @SVB_PGB is “Er is een algemene fout opgetreden. Probeert u het later nog eens.”. Helaas geen verder log of details. Wat nu? 2/2

En daarom ben ik gistervavond een paar uur bezig geweest met opnieuw proberen en daarna PDFjes van de declaraties te maken. Die ik nu weer mag renamen omdat de bestandsnamen te lang zijn.
