FastMM4 FullDebugMode quick tip: don’t forget to give your EXE access to the correct FullDebugMode.dll
Posted by jpluimers on 2014/03/06
If you run FastMM4 in FullDebugMode, then here are two tips that new (and sometimes existing users) often overlook:
- If you set the
FullDebugModedirective in the IDE, build your project. - Don’t forget to give your EXE access to FastMM_FullDebugMode.dll (x86), or FastMM_FullDebugMode64.dll (x64) which are stored in the FastMM4 download and in the precompiled directory of the source code.
Either put that DLL in your path, or copy it to your EXE directory. - Make sure your EXE can write in the directory of the EXE.
The first makes sure all units are compiled with FullDebugMode (Delphi does not always do that automagically).
The second makes sure your EXE can access the DLL that writes out your *MemoryManager_EventLog.txt file containing memory leaks and other issues FastMM4 detected.

When DelphiSpeedup cannot register itself in Delphi on Windows Vista/7/8
Posted by jpluimers on 2014/03/06
Every now and then I need to go back to an old Delphi version, which nowadays means try and get it and all the tools installed on something newer than Windows XP.
When installing on Windows Vista and up (I usually run Windows 7 or 8.1), the DelphiSpeedUp installer barfs with something like this:
---------------------------
Installdelphispeedup105
---------------------------
Cannot register DelphiSpeedUpLoader.bpl.
---------------------------
OK
---------------------------

Not only only important in Windows PowerShell: “Whitespace, Please” (via: TechNet Magazine)
Posted by jpluimers on 2014/03/06
In this series of PowerShell postings, the below quote by Don Jones from Concentrated Technology is a must:
Proper formatting, including a little whitespace here and there, can make your Windows PowerShell commands a heck of a lot easier to understand.
But please don’t limit this to PowerShell code.
I see too many code at clients, even at conferences and magazine articles that are badly formatted.
Even more important: when you ask or provide for help on a forum or community site: please properly format your code examples. That makes it much easier for your audience (often yourself) to grasp the meaning.
For PowerShell: note that most syntactic elements provide for a very natural line continuation (so you can write really readable code), except for CmdLets, so often you will see { at the end of a line to make the most readable code.

Time for a new “-goto cleanup;+goto fail;” T-Shirt; The Story of the GnuTLS Bug (via: existential type crisis)
Posted by jpluimers on 2014/03/05
A new *n*x bug got discovered in TLS certificate handling that is similar to the recently discovered iOS and OS X “goto fail” security issue.
This time the fix is performing a few replacements linke this:
-goto cleanup;
+goto fail;
Plus one addition:
+fail: // ADDED
+ result = 0;
Applications depending on GnuTLS are affected (there are other libraries providing TLS like OpenSSL), which are many.
Two must-do things:
- Closely watch the Linux, BDS, other *n*x and application security updates, as exploits will be available soon
- Read via: existential type crisis : The Story of the GnuTLS Bug as it explains the bug, tracks down the cause, and talks about “lessons to learn”.
I’m with Jan Wildeboer here and updates should get in very soon: Read the rest of this entry »

PowerShell: Do not take a shortcut while testing NULL values.
Posted by jpluimers on 2014/03/05
A while ago I found a blog post explaining how to shortcut testing NULL values with PowerShell.
Do not do that!
I agree with the quote on the blog:
One thing you may not forget is that Powershell is a lot more friendly for NULL values than C#, so don’t forget to check your objects for NULL values. In Powershell this is very clean and easy to do.
But it is also easy to get wrong:
To see if a variable is null, simply check:
If (!$Variable) {some action}Conversely, to verify if the variable has any value:
If ($Variable) {some action}
Just a few examples. Now quess the outcome for all of them.
$a=$null; if ($a) {"'$a' has VALUE"} else {"'$a' is NULL"}
$a=$false; if ($a) {"'$a' has VALUE"} else {"'$a' is NULL"}
$a=0; if ($a) {"'$a' has VALUE"} else {"'$a' is NULL"}
$a=''; if ($a) {"'$a' has VALUE"} else {"'$a' is NULL"}
$a=""; if ($a) {"'$a' has VALUE"} else {"'$a' is NULL"}
$a=1; if ($a) {"'$a' has VALUE"} else {"'$a' is NULL"}
Now take an educated guess on the outcome. Read the rest of this entry »

One of the niceses PowerShell 3.0 new features: Simpler Where Filter Syntax
Posted by jpluimers on 2014/03/04
You can check out which PowerShell you have by executing the $Host.Version or $PSVersionTable.PSVersion on a line. You can even switch versions by applying the PowerShell -version switch on the command-line and they will both change.
One of the great features of the new PowerShell 3.0 features (besides New and Improved PowerShell 3.0 Cmdlets) is a simplified Where Filter Syntax.
So: this is how I get the PowerShell version information the easy way from a command prompt:
PowerShell $PSVersionTable.PSVersion
