Some interesting bits on interface delegation including a class helper trick – via Stefan Glienke – Google+

Posted by jpluimers on 2019/01/17

Every time he finds a new compiler use, I’m all like “wow!”. This time [WayBackStefan Glienke – Google+: One of these rare moments when the compiler positively impresses me found a new way to make single responsibility principle easier to attain by using a class helper to resolve interface delegation.

In the comments are a few nice tidbits on what the compiler emits in order to implement interface delegation and reference counting.

Posted by jpluimers on 2019/01/17

If you dare using Delphi 10.3 Rio instead of waiting for Update 1 to stabalise (and hopefully speed up things), you might want to try the development snapshot of [WayBackIDE Fix pack for Rio – Page 2 – Delphi Third-Party – Delphi-PRAXiS [en] that got released last week (thanks Andy!):

A new development snapshot of IDE Fix Pack for 10.3 Rio is available.

  • Added: DFM Streaming optimizations
  • Added: FillChar uses Enhanced REP MOVSB/STOSB cpu feature if available for large sizes.
  • Added: Enabled CPU LOCK string assignment optimization for local variables
  • Added: -Oe (experimental optimizations) and -x-cgo compiler option extension (Remove of some unneccessary push/pop operations)
  • Added: Expression Evaluator allows array access to pointers even if the type wasn’t declared with {$POINTERMATH ON}

some links that helped me fiddle with iframe elements

Posted by jpluimers on 2019/01/16

I need to document this properly later, but here are some links I used when fiddling with iframe elements:

A few things I learned:

  • You can either put the iframe elements in different divs then arrange the divs, or put a different ID on each iframe and arrange the iframe. In either case you will need a float: left; in your style and a width: 100vw in the div around all your frames.
  • Be aware that 100% isn’t 100% out of the box: default browser styles have a margin around your page and a border around an iframe.
    So you will need to fiddle with margin and border-width inside your styles for body and iframe. Easiest is to set them to none or 0.
  • Viewport width/height works easier for me than raw %.
  • For one-off situations, I like the good old meta refresh over fiddling with JavaScript.

Top 25 Most Dangerous Programming Mistakes

Posted by jpluimers on 2019/01/15

10 years after the publication of the [WayBack] Top 25 Most Dangerous Programming Mistakes, the list for me is still the same.

You can see this from the CWE/SANS revisions: 1.0 in 2009 until 1.0.3 in 2011: not much changed.

oath-toolkit / oath-toolkit · GitLab

Posted by jpluimers on 2019/01/15

Interesting library with ditto command-line tools: [Wayback/Archive] oath-toolkit / oath-toolkit · GitLab.

It allows you to perform all sorts of OAUTH operations from your code or terminal window including generation and verification of OAUTH tokens through [WayBackOATHTOOL.

Which allows you to do TOTP “zero fucktor” authentication. [WayBack/Archive] Zero Fucktor Authentication – Kristian Köhntopp – Google+: [WayBackZero Factor Authentication – The Isoblog.

The project has it’s home at [WayBackOATH Toolkit, but the repository has done some traveling and for now ended up at GitLab: [Wayback/Archiveoath-toolkit / oath-toolkit together with the web-site source [Wayback/Archive] oath-toolkit / website.

Interesting thought [WayBackIn windows, can I redirect stdout to a (named) pipe in command line? – Super User.

The only problem seems to be a good way of creating/removing those pipes.

Life after Google+ – Lars Fosdal: Friends+Me Google+ Export tool.

Posted by jpluimers on 2019/01/11

A little while ago, I blogged about Life after Google+ – Lars Fosdal. In the mean time, Lars has made a lot of progress exporting the community [WayBack] Delphi Developers – Google+ (which has moved to en.delphipraxis.net !).

He is a heavy user of the Friends+Me Google+ Export tool, which basically is an actively maintained web scraper with standard output targets:

[WayBack] Google Plus Exporter – Medium: Export your Google+ feeds to WordPress, Blogger, and JSON.

It does not depend on the G+ REST API: “the app is using web scraping and will keep working until the bitter end”.

Quite a bit of that information and the feedback he has is in this thread: [WayBack1/WayBack2] Hi Everyone, We’ve just released Google+ Exporter, an application that helps you to export your Google+ feeds (profile, pages, collections, communities… – Friends+Me – Google+

Of course G+ does not save the whole thread in the WayBack machine, so here it is copy-pasted (unformatted; maybe I will format it later):

from a WSDL import: empty “Reference.cs” – Google Search

Posted by jpluimers on 2019/01/10

A search for empty “Reference.cs” – Google Search seems to indicate this happens with referenced types that – despite turning off that option – from the Visual Studio 2017 IDE sometimes results in an empty Reference.cs.

My solution: import in an empty project, then move the reference to the existing project and add it.

Some ideas to show a Google Calendar on a TV using a Raspberry Pi and HDMI output

Posted by jpluimers on 2019/01/10

Using OpenSuSE Tumbleweed E20 on Raspberry Pi 3: accessing the enlightenment desktop over VNC after automatic logon I wanted to buy an on-line read-only diary to help my mentally retarded brother see what his next few days are going to be like.

He increasingly has difficulty handling a paper agenda and has an agenda with 30 minute blocks like [Archive.isbol.com | Bureau Agenda 2017 – 1 dag per Pagina | 0041560163422 | Boeken (and the [Archive.is] picture on the right), but actually he needs 15 minute blocks during some portions of the day.

We call that kind “bureau agenda” which I think translates well into “desk diary”.

They were quite different from the agendas I used to have at school (:

For most school mates, they were more like this:

Had je een O’Neill of ging je voor De Familie Doorzon? De oude agenda’s uit je middelbare schooltijd zijn de verpersoonlijking van je eigen puber-ik. Afgelopen weekend startte in het Nationaal Onderwijsmuseum in Dordrecht de toffe tentoonstelling Grow Up over die vuistdikke, volgeplakte agenda’s.
