Mac: when “Save time with right-click sharing from your Google Drive folder” fails…

Posted by jpluimers on 2018/07/09

A few years ago, Google Drive introduced this:

For those looking to share files more quickly, listen up. You can now share with others directly from the Google Drive folder on your Mac or PC. To share a file while inside your Google Drive folder, simply right click the file, select “Google Drive” and then click “Share.” This new feature is rolling out over the next few days.

However, sometimes it fails. And the menu has changed as well.

By now the menu looks like this:

  • “View with Google Drive”
  • “Share using Google Drive”

If those do not appear, then:

Try to stop, then start Google Drive.

If that fails:

Automated “take-down” algorithm simulation: thread by @AlecMuffett: “Regards Article13, I wrote up a little command-line false-positive emulator; it tests 10 million events with a test (for copyrighted material […]” #Article13

Posted by jpluimers on 2018/07/08

Simulation of the proposed law effects are easy: [WayBack] Thread by @AlecMuffett: “Regards Article13, I wrote up a little command-line false-positive emulator; it tests 10 million events with a test (for copyrighted material) […]” #Article13

What it shows that an automated test for content-originality only succeeds when there are a truckload of copyrighted-material uploads than original-content uploads:

about 1 in 67 postings have to be “bad” in order to break even

So if you have less than 1% false uploads, even with a 98.5% accuracy (which is very very good for a take-down algorithm!), you will piss off far more good items wrongly marked as false positive, than bad items correctly marked bad.

When the accuracy gets less, you piss-off far more original-content uploads, but also catch less copyrighted-material uploads..

This is called the a far less “sexy” term False positive paradox – Wikipedia, which is a specialisation of the far mor dull sounding Base rate fallacy – Wikipedia

Online markup conversion from markdown to mediawiki: pandoc

Posted by jpluimers on 2018/07/06

Since Mediawiki needs an extension to display Markdown, and many MediaWiki installations do not have that extension, I was looking for an online conversion from markdown to MediaWiki markup.

Luckily the Pandoc try has this conversion: [WayBack] Try pandoc! Markdown(pandoc) -> MediaWiki

These links helped me get there:

A Wi-Fi enabled 1990 Macintosh Classic built with LEGO, powered by a Raspberry Pi Zero running docker and a 2.7″ e-paper display by EmbeddedArtists.

Cool stuff!

Raspberry Pi zero W notes

Posted by jpluimers on 2018/07/06

Launch dates:

Now you only need a memory card and a camera module to make a nice “CCTV” system with plenty of choice. More details here:

Depending on what and when you record video, you might want to consider an IR capable camera. In Raspberry Pi land, they call them NOIR (which stands for No IR, meaning they leave out the IR filter which means they can record IR).

You can use Linux API calls directly from Delphi 10.2 and up

Posted by jpluimers on 2018/07/05

Paul TOTH figured this out:

you can use any Linux API but it’s not trivial.

  1. you have to install the “dev” library under Llinux, like “apt-get install xxx-dev” for the xxx API
  2. you have to update the Linux DSK in Delphi
  3. you can declare the API as externals function as usual
  4. now you can compile and deploy the application.

If you miss the steps 1 or 2 you’ll have a linker error.

Source: [WayBack] Dear… Delphi 10.2 Tokyo, can i use linux api directly? like ‘fcntl(….)’.

And there is this great blog post that I found later by [WayBack] Allen Drennan: [WayBack] Importing third-party Linux libraries on Delphi 10.2 Tokyo – grijjy blog

I totally forgot that Delphi has had a function to get the current executing thread – Stack Overflow

Posted by jpluimers on 2018/07/05

While updating some old code fiddling with the[WayBack] GetThreadId function, I wanted to have some TThread wrapper around it. I had totally forgotten there has been already a means for this since Delphi 2009 (which initially had a bug, but that was worked around at first and fixed later): [WayBack] CurrentThread.

The latest version of Delphi, Delphi 2009, has a CurrentThread class property on the TThread class.

This will return the proper Delphi thread object if it’s a native thread. If the thread is an “alien” thread, i.e. created using some other mechanism or on a callback from a third party thread, then it will create a wrapper thread around the thread handle.

Visual Studio – Add File As Link

Posted by jpluimers on 2018/07/04

Since I forget where they hid the [WayBack] Visual Studio – Add File As Link feature, two images from the linked post:

  1. The icon in the link is different from the normal file:
  2. Adding as a link is  not a separate menu item, but a modification of the file open dialog overlaying the default Add button with two more options: Add; Add as Link (note Show Previous Versions is a feature of non-Home version of Windows Vista and up).
    Do not double click the file name, as that will add (AND COPY TO THE CURRENT PROJECT DIRECTORY !!!1!!!) that file to your current project.

A step by step instruction is at [WayBack] c# – Add File as a Link on Visual Studio – Debug vs Publish – Stack Overflow.
