64bit

Visualizing address space We have seen claims of “that should be enough” proven false so often. We somehow knew that 16 bit of address space would run out some day. We're rapidly approaching the point where 32 bit will no longer be enough to store the number of seconds since epoch (1970-01-01), and it has not been enough to address all the memory on our hard drives for quite a while. So it's natural when we are reluctant to believe that 64 bit will be “enough forever”.

Amiga's LibraryBase AmigaOS was an operating system that did not support memory protection. All tasks ran in a single (physical) address space. Of course this is not desirable from a modern OS standpoint. But how it was done can serve as an architectural example to hobbyist

Cygwin Getting the Cygwin Installer The Cygwin installer executable is available at https://cygwin.com/setup-x86_64.exe. You will need it again later on, as it is also the package manager for Cygwin. So make sure you save it (instead of just executing it this once). Spaces in Path

Broken graphics on boot Some graphics cards don't really “play ball” with the default Linux Mint setup. Luckily this is easy to circumvent. LiveUSB Just select “compatibility mode”. You will get a much lower resolution, but that is good enough for installation.

Shell Logfile Something that makes product support really difficult is if the interesting output from the customer's script run doesn't end up in the logfile (or the logfile says something different from what the customer saw). Especially if the customer already closed the window and can only tell you what he saw from the back of his head. Fortunately, there's a very easy way to make sure you catch all of your script's output.

Boost.Spirit Boost.Spirit is a framework for writing parsers. In a sense, it's a replacement for the Lex / Flex and Yacc / Bison tools. One of the advantages of Boost.Spirit is that it does this in plain C++ source, removing the dependency on additional tools, their individual syntax and build steps.

SSTR() Note: The C++11 construct std::to_string( x ) is more efficient than this. See end of article for perfomance comparisons. Preface Quite frequently, a C++ coder will face the issue of turning some value or object into its string representation (usually for output of some kind). Conveniently, when you want to write to terminal or a file, this can be done quite easily using the commonplace

Creating a two-way SVN <> GitHub sync Intro When migrating PDCLib from Bitbucket / Mercurial to a local Subversion, I wanted to provide the advocats of Distributed VCS with a way to get the PDCLib sources “their way”. As Erin Shepherd pointed out in one of the many emails we exchanged, Git seems to have pretty much won the Version Control battle. I still much prefer Subversion, but I realize that being present on GitHub would certainly not hurt the project.

Vim Studio Last job, I was working on C# with JetBrain's Rider IDE. Which has a really nice Vim plugin, IdeaVim. I was content. Now I am back to working on C++, with Visual Studio. Which has left its Vim plugins (VimEmu, VsVim) in the dust with the 2022 update. Things just don't work all that nicely.

Why People Hate Microsoft ...and Linux. In a discussion on OSDev.org, the question “why do software developers hate Microsoft?” came up. I wrote my take on the subject, and user eddyb remarked: " Maybe it should be put somewhere on the front page or given a wiki page. That's a really good explanation Solar, thanks :)
