A great guide is at PeStudio Standard [WayBack] which despite the name does an in-depth explanation on how to use this great tool.

Warning: C64 geek pr0n! A Mind Is Born

Posted by jpluimers on 2017/04/20

Geek pr0n on the C64:

Making a demo in just 256 bytes would be a formidable challenge regardless of platform. A Mind Is Born is my attempt to do it on the Commodore 64. In the absence of an actual 256-byte compo, it was submitted to the Oldskool 4K Intro compo at [WayBack] Revision 2017, where it ended up on 1st place.

use vmrun – via How do I find the IP address of a virtual machine using VMware Fusion? – Super User

Posted by jpluimers on 2017/04/20

Note this works only when the VMs have VMware Tools installed (more on that below):

VMWare provides, not surprisingly, a built in tool for this, vmrun. It’s under /Applications/VMware Fusion.app/Contents/Library/vmrun although it has moved around in other Fusion releases a bit.

🍺 vmrun list Total running VMs: 1 .docker/machine/machines/myvm.vmx
🍺 vmrun getGuestIPAddress ~/.docker/machine/machines/myvm.vmx 172.16.213.128

via: How do I find the IP address of a virtual machine using VMware Fusion? – Super User [WayBack]

vmrun [WayBack] is barely documented and most of is in PDF of which this is the most recent I could find: www.vmware.com/pdf/vix180_vmrun_command.pdf [WayBack]

Based on the above path, I added this to my ~/.bash_profile file:

alias vmrun='/Applications/VMware\ Fusion.app/Contents/Library/vmrun'
alias vmrun-list-running-VMs='vmrun list | grep vmx'
vmrun-list-ipv4-of-running-VMs()
{
  vmrun-list-running-VMs | while read line ; do echo $line && vmrun getGuestIPAddress $line; done
}

Now I can do this:

$ vmrun-list-ipv4-of-running-VMs
/Users/jeroenp/VM/W81Entx64DelphiRegression.vmwarevm/W81Entx64.vmx
172.16.172.135

These are the messages I observed:

The first one means a machine is running but has no VMware Tools installed. For an OpenSuSE machine you can install it with zypper install open-vm-tools, for other Linux systems read VMware Tools auf Ubuntu, Mint, CentOS oder openSUSE installieren | ITrig [WayBack]

Dark corners of Unicode / fuzzy notepad

Posted by jpluimers on 2017/04/20

You think you know Unicode? Think again, then read [Wayback] Dark corners of Unicode / fuzzy notepad.

On basics, sorting, comparison, decomposition, composition, width, whitespace, encoding, emoji, interesting code planes and dark corners. Lots of dark corners.

The examples are in Python, but hold for almost any programming language

When BRCC32 throws `Fatal error Illegal macro definition in command line or defines page.` in a DUnitX project

Posted by jpluimers on 2017/04/19

I had a Fatal error Illegal macro definition in command line or defines page. thrown by BRCC32.exe in one of my Delphi projects.

As cgrc.exe could build the .rc file [source in Russian; WayBack], I reproduced it from the console with an Empty.rc file that has no content. That way I could rule out file content: now it had to be command-line arguments which is a different cause than any of the search results I found before.

My project was based on one of the DUnitX test projects. It ran in Delphi XE8, but the Delphi version doesn’t matter as BRCC32 hasn’t been updated since 1999.

Further below are the failure/success examples; this went wrong:

  1. DUnitX uses the DUNITX-DEBUG define to enable debugging of DUnitX itself in DUnitX.inc which also supports the DUNITXDEBUG define in the same area.
  2. Delphi will translate a .RC file in a project into a BRCC32.exe call adding the project conditional defines and search paths
  3. BRCC32.exe doesn’t like hyphens in conditional defines throwing a non-descriptive error Fatal error Illegal macro definition in command line or defines page.

So either removing DUNITX-DEBUG or changing it into DUNITXDEBUG solves the problem. Hence my pull-request.

When your markdown README files on GitHub are broken as of lately

Posted by jpluimers on 2017/04/18

Basically below gist tells it all.

Many repositories on GitHub do not have whitespace between the # and headings. This is against the specs, so GitHub fixed their rendering engine. Which means now many files do not render nicely any more.

So if you have headings like this:

##text

Fix them to be like:

## text

If your GitHub repository has less than 50 starts, you did not get an automatic pull request to fix it from https://github.com/bryant1410/readmesfix so you can either:

–jeroen

Recently, GitHub introduced the change in how atx
headers are parsed in Markdown files.

##Wrong

Correct

While this change follows the spec, it breaks many existing repositories. I took the
README dataset which we created
at source{d} and ran a simple
regexp PySpark job.
It appeared that more than 500,000 repositories have README files which are rendered
with invalid headers.

Among those 0.5mm, there are more than 10,000 which have more than 50 stars. They were
uploaded to data.world.

Bash that JSON (with jq) — Librato Blog

Posted by jpluimers on 2017/04/18

Glueing together APIs requires working with JSON: parsing it, extracting it, transforming it. JQ is a fast, lightweight, flexible, CLI JSON processor, that does the job well. Learn how to use it by getting your hands dirty with a JSON blob that represents the open issues in the public Docker GitHub repository.

Delphi and the joy of Compiler Intrinsics – I cant use “Length” as a TFunc…

Posted by jpluimers on 2017/04/18

One of the reasons I favour using RTL based functionality over Delphi Intrinsic Routines like Length, Abs and others is that you cannot use compiler intrinsics in Generics. For instance Length is not compatible with TFunc<string, Integer> unless you declare it yourself like function StringLength(value: string): Integer; as otherwise you get en E2029 error (in this case the cryptic '(' expected but ';' found).

It’s one of the many areas where the Delphi compiler developers took a shortcut, but in this case I think the results are somewhat good.

Other reasons for using the RTL over compiler intrinsics have to do with scoping: the intrinsics are in the global scope which can clutter what you’re trying to work on.

So I much rather use the file and stream related functions when I’m actually working with a file or stream. For instance Assign for me has nothing to do with a file outside of a file context (it’s the reason AssignFile exists in the first place).
