Be sure to read the details in Trying to recover from enhancement software that generates fake input incorrectly – The Old New Thing [WayBack] (much more Old New Think stuff below):
The most insightful part for me was this diagram listing where various methods enter the message pipeline (I added the GetMessage/PeekMessage entry):

The first implementation of Compiler Explorer supports many versions of the gcc, clang and icc compilers on ARM, ARM64, AVR and x86 targets.
On the left you type your C++ code, on the right you see the resulting assembler code optionally with byte code and colorised so you can correlate the C++ lines with the assembly.
A great way to start the year: learning new things!

A long while ago, but still an interesting discussion: Is there a predictable order of execution for Class Constructors? leading to these links:

Some of the [Wayback] Ken Thompson – Wikiquote entries come from a great [Wayback] 1983 ACM Turing Award Acceptance Lecture [Wayback] “Reflections on Trusting Trust”.
That lecture used to be on http://cm.bell-labs.com/who/ken/trust.html
But it isn’t, and was not in the WayBack machine and neither in the Google Cache [Archive.is] because of the [Wayback/Archive.is] robots.txt. Historic link rot galore!
Edit 20210728: by now it is in the Wayback machine again; the earliest archived copy is from 2001, it also shows that as of april 2015 it is gone from the bell labs server.
The lecture is about [Wayback] compiler viruses and viruses actually did this at least a few times: Wayback: Delphi in 2009 and to [Wayback] XCode in 2015.
A few nice links from [Wayback] ACM Classic: Reflections on Trusting Trust – Google Groups though:
And archived versions of (I hope accurate) copies of the article:
Finally I found a PDF copy of the original ACM prints that Greg Ganger of Electrical and Computer Engineering at Carnegie Mellon University has online. It’s archived too.

In the continued “floating point code is hard for most software developers” series:
[WayBack] Why does the Windows calculator generate tiny errors when calculating the square root of a perfect square? – The Old New Thing
Because it doesn’t know that it’s a perfect square.

Below is the the speaker line up. It’s an awesome bunch of guys and there’s plenty coverage for English speaking attendees: English sessions are below the speaker list.

There are odd things with the InitialKeyboardIndicators registry setting. Technet only documents bitflag value 2.
According to the docs it should be a bitflag, but sometimes you encounter InitialKeyboardIndicators value 2147483648 (0x80000000) especially as part of the .DEFAULT profile at HKEY_USERS\.DEFAULT\Control Panel\Keyboard.
The problem I had was having these symptoms:
InitialKeyboardIndicators=0 in my local profile at HKEY_CURRENT_USER\Control Panel\Keyboard.After reading Num Lock problem: Strange number in InitialKeyboardIndicators in Registry, I set both values to 0.
Now that it is 0 in both at HKEY_USERS\.DEFAULT\Control Panel\Keyboard and HKEY_CURRENT_USER\Control Panel\Keyboard, symptoms 4-5 still hold. Strange.
It is not the same problem as Num Lock state not retained after resume from Hybrid Shutdown in Windows 8 and Windows Server 2012.
If it persist, I might just put a script in: [Partially Solved: re-wired keyboard lol] Registry key “InitialKeyboardIndicators” NEVER keeps NumLock ON + ScrollLock ON (6) at startup and reverts back to NumLock ON (2).
