Windows software developers – High DPI awareness: the developer Y2K (or is it EUR introduction) of our time.

Posted by jpluimers on 2014/11/05

An interesting statement by Steve Maughan:

Looking at how many High DPI awareness or lack of is the developers Y2K of our time.

Looking at the trouble Windows and Windows applications in general have with High DPI (more in general: resolution independence). I think it rates even higher: as the EUR introduction problem of our time.

What do you think?

Windows Timer Resolution: Megawatts Wasted (via: Random ASCII)

Don’t increase your Windows Timer Resolution. And keep an eye on programs that do:

Raising the Windows timer frequency is bad. It wastes power and makes your computer slower. Routinely doing this in all sorts of programs that end up sitting idle for hours really needs to stop.

You can use ClockRes to monitor the time resolution and what programs changed it.

Reminder to self: you cannot repeatedly draw anti-aliased text without damaging the background

Posted by jpluimers on 2013/04/11

A small duh moment when I found this out myself the hard way: when repeatedly drawing anti-aliased text, it will alter the background on each draw.

So you cannot do that. Not in Delphi, not in .NET, not in Cocoa, nowhere (:

Great session on how to prevent SQL Injection Myths and Fallacies

Posted by jpluimers on 2012/08/15

A few weeks ago, Bill Karwin did a must watch webinar on the prevention SQL Injection titled  “SQL Injection Myths and Fallacies“.

Bill Karwin (twitter, new blog, old blog, Amazon) is famous for much work in the SQL database community, including InterBase/Firebird, mySQL, Oracle and many more.

He also:

Anyway, his webinar is awesome. Be sure to get the slides, watch the replay, and read the questions follow up.

How to install Windows 7 on a virtual hard disk (VHD) in 10 steps (via: Guides & Tutorials)

Posted by jpluimers on 2012/03/12

Handy when working with Microsoft Surface: install your development environment on a separate VHD that you can boot as your physical machine (Microsoft Surface SDK does not like being run in a Virtual Machine):

If you accept the constraints described above, I propose the following procedure, which I think is the easiest way to install Windows 7 on a virtual disk in multi-boot

Note: Within the VHD you can still access all the files on your physical HD.
