During a recent code review, I bumped into a couple of C# constructors having boolean parameters, leading to the dreaded magic booleans code smell.
This reminded me of the infamous Avoiding Booleans post on Coding Horror, which now is almost 10 years old.
To celebrate, I will coin the Dutch phrase when marking these in a review:
Boolean parameters en literals zijn vrijwel altijd een zwaktebod. Een teken dat beter nagedacht moet worden over het doel van de code.
The Dutch word zwaktebod is used when bidding Bridge using the Acol system. It is the equivalent of a “weak takeout” response to a bid of 1 NT (notrump or no trump, in other languages sometimes sans atout).
The English translation is just about this:
Boolean parameters and literals virtually always are a sign of weakness. It indicates you need to give more thought to the goal of the code.

Thanks [Wayback] Jørn Einar Angeltveit for sharing this a while ago:
A session by Jon Skeet and Tony the Pony (which has strong teeth) presented during the Polish DevDay 2013 in Kraków, Poland.
[Wayback] +Jon Skeet’s speech [Wayback] “Back to basics” is really a good watch.
In a funny way, he explains why the simplest fundamentals of computer software text, dates and numbers can cause some real headache for the programmer…
In case you didn’t know: Jon Skeet is “Chuck Norris” on [Wayback] stackoverflow.com:
The subtitle is “the mess we’ve made of our fundamental data types”.
Some of the topics covered:

When installing SQL Server 2008 Service Pack 3 related updates, some don’t like compressed directories (even if the database files themselves are uncompressed).
I found this holds at least for KB2977321 and KB2285068.
For x86 systems, ensure these directories are not compressed:
C:\Program Files\Microsoft SQL Server
C:\Program Files\Microsoft SQL Server Compact Edition
For x64 systems, ensure these directories are not compressed:
C:\Program Files\Microsoft SQL Server
C:\Program Files x86\Microsoft SQL Server
C:\Program Files x86\Microsoft SQL Server Compact Edition

Older Windows versions than 8.x will not correctly expand %APPDATA% or %LOCALAPPDATA% in environment variables: User variables are not resolved correctly in Windows..
This even happens when the registry storage of the environment variables are marked as REG_EXPAND_SZ under these keys:
Basically there are four categories of Windows versions:
- For Windows 10.x this is fixed.
- For Windows 8.x and Windows Server 2012 R2, there are updates in KB2919355.
- For Windows 7.x and Windows Server 2008 R2, there is a hotfix.
- For older Windows versions, there is no solution.

Great post by Marjan Venema when you need to migrate your old Delphi programs to the modern Delphi world: [Wayback] 20 resources on migrating to Unicode with Delphi | Software on a String.
I’m glad that some of the links overlap with what I posted and presented in the past at:
Well done Marjan!
