Bitsavers published 2 new Logitech PDFs:
Who didn’t have a Logitech mouse back then?
I had the C7, various MouseMans, and a few more modern mice. Why not all mice? I developed RSI in the DOS era, ending up with TrackPoints and more recently Apple touchpads)
I remember the Logimouse C7, not because it was from Logitech, but because it was available from so may OEMs. Long before Logitech built OEM mice for Apple, they were founded in Apples, Swizerland.
The cool thing: the Programmers Toolkit had examples in Modula-2. I used that as a base to write quite some Turbo Pascal code for mouse handing.
Oh: Bitsavers does have a Logitech Modula-2 PDF online too for quite some time. I mentioned that in More Old Micro Cornucopia issues on BitSavers from 1987 and 1988.

Wow, I thought WPS always required a button press on a device.
It appears it doesn’t on many device, and cracking therefore is way to easy: How to Crack a Wi-Fi Network’s WPA Password with Reaver.

I bumped into the below answer that I gave a while (what is 4 years in a developer’s life ) on StackOverflow.
It is about Delphi Design Patterns. Sepcifically the Factory Pattern, and explains how virtual constructors implement it.
They are one of the 3 corner stones on which the component based Delphi form designer and object inspector are built:
- Virtual constructors
- Properties (events are just a special form of property)
- Run-Time Type Information.
So here it goes: Read the rest of this entry »

A while ago, I wrote about .NET/C# duh moment of the day: “A char can be implicitly converted to ushort, int, uint, long, ulong, float, double, or decimal (not the other way around; implicit != implicit)”.
There is another duh moment having to do with the various C# operators like += which is being described as being
a += b
is equivalent to
a = a + b
You might think that this also holds:
a += b + c
is equivalent to
a = (a + b) + c
But Eric Lippert has explained this is not the case: it is equivalent to:
a = a + (b + c)
In his explanation, he also shows the confusion can get you very surprising results if you mix string, chars and ints in the expression: depending on the statement and ordering, you either concatenate characters, or add ints to characters.
He also recommends you should not do concatenation: either use String.Format, or StringBuilder. I totally agree with that.
Recommended reading!

2 more issues got on-line both close to a 100 pages each:
So the only issues missing are #28, #30 and #31.

I still see a truckload of projects that connect to SQL Server do this using OLE DB or the Native SQL Client.
All OLE DB access to SQL Server has been deprecated, not only from regular access, but also from SSIS.
These are the only ways you should connect to SQL Server:
- SqlClient (managed code)
- JDBC (Java)
- ODBC (for native code)
For instance, these have been deprecated (for each one, I linked to the oldest SQL Server version where they were made available for):
- SQLOLEDB
- SQLNCLI
- SQLNCLI10
- SQLNCLI11
- SQLXMLOLEDB.3.0
- SQLXMLOLEDB.4.0

Every once in a while, a hidden POWERPNT.EXE consumes 100% of one CPU core (on a single core, that is deadly, on a multi-core system it drains your battery pretty fast).
This was the cause:
One reason is you have preview pane enabled and have selected a PowerPoint File. To preview it an invisible copy of PowerPoint is opened and may not close when you deselect. This doesn’t normally use much cpu though.
