Show missing hard disks in the Finder sidebar | MacIssues

Posted by jpluimers on 2014/10/23

Besides the two solutions to the Show missing hard disks in the Finder sidebar problem, I also learned this shortcut today:

open a Finder window and press Shift-Command-C to go to the top level of your computer

Thanks Tophler Kessler!

Barry Kelly on how the Delphi Compiler used to be compiled (via: Google Groups)

Posted by jpluimers on 2014/10/23

not 100% accurate any more (now that the compiler gets more and more LLVM), but still accurate for most of the x86/x64 parts: Barry Kelly explaining how the Delphi compiler is built.

Some more of his posts.

Barry Kelly on “Implementing Closures” in Delphi (via: Google Groups)

Posted by jpluimers on 2014/10/22

It is always nice to see one of the compiler engineers write down how something was implemented.

In this case, Barry Kelly explains in comp.compilers on Implementing Closures in Delphi 2009. The post is about 4.5 years old, but still very relevant.

About 9 months earlier, he participated in a Reddit thread about a similar topic. Worth reading too!

Max OS X: Tunderbolt Ethernet trouble shooting (via: Ask Different)

Posted by jpluimers on 2014/10/20

Thunderbolt to Gigabit Ethernet AdapterEvery once in a while my Gigabit Thunderbolt Ethernet adapter would show this in the Network Settings:

Status: Cable Unplugged Either the cable for Thunderbolt Ethernet is not plugged in or the device at the other end is not responding.

That’s not much use: it does not tell if the Thunderbolt or the Ethernet side has a problem.

Luckily, the How to force Thunderbolt-ethernet connection when switching networks without restarting computer? at Ask Different indicates the System Information will give you more information about the Thunderbolt side of things. Read the rest of this entry »

Some linkes Apple Retina MacBook with GSoD or sleeping issues

Posted by jpluimers on 2014/10/17

Last year, I had a thing similar to GSoD (not the ATI GSoD): a grey screen when waking up my Retina MacBook Pro. Nothing but rebooting helped. And I have not found a cause, but it also did not re-appear.

Some links on Macs having GSoD, or sleeping issues:

Some on-line XML tools I use often

Posted by jpluimers on 2014/10/16

A big part of the cloud is not about storage, it is about on-line tools that run in your web-browser so you do not have to install them locally.

Quite a bit of my XML work can be done with on-line tools like these:

Continua v1.5.0.338 got released last week (via: Version 1.5 History | Continua CI – Page2RSS)

Posted by jpluimers on 2014/10/15

Two changes I really like in the new v1.5.0.338 build of Continua CI version log history:

  • Update: Now logging the environment variables passed to actions in the build log
  • Update: Better messages when handling errors expanding variables

That makes debugging build issues a lot easier, as many of them are related to (environment) variables.

The Delphi MESSAGE directive: don’t forget quotes!

Posted by jpluimers on 2014/10/15

The Delphi MESSAGE directive is a very powerful one, you can generate compiler hints, warnings and errors with it, even fatal ones that abort compilation.
The compiler will return error codes H1054 (hint), W1054 (warning), E1054 (error) or F1054 (fatal error), which in the documentation are known under the catch-all x1054.

You need to take a bit of care with message directives, especially with the quotes. For instance

{$Message Error 'Not implemented'}

gives you the error below, but continues compiling:

[DCC Error] E1054 Not implemented

However, if you forget the single quotes

{$Message Error Not implemented}

it gives you error E1030  (not x1054), which is a bit confusing as it is a catch-all for invalid directives:

[DCC Error] E1030 Invalid compiler directive: 'message'

Here is a full example (now moved to bitbucket) of all the message directives and compiler reactions you can get: Read the rest of this entry »
