Simple computer graphics demos are often developed as console applications. Having the console window is simply convenient for debug output. However, if we then show these demos on our stereo powerwall, the console window flashing on program start is massively disturbing. That is why I take some time and wrote a little tool. It starts the console application, hides the console window, but captures the output. This way, we can still check what happened if something does not work.

I present the HiddenConsole:

NuGet is a handy package system for Visual Studio. Originally meant for Dotnet libraries it was extended some time to support native C++ projects as well. The only catch is, that the packages need to be made especially for NuGet. There are some, but by far not all which one (I) needs for the daily work. Most problematic is that many packages do not support Visual Studio 2013. And that is even today, as Visual Studio 2015 is almost here.

So there is only one thing to do: join the fray! Well, I could stay out of it and continue to grumble about it, but let’s just keep that as plan b. So, here it is; my first NuGet package:

the AntTweakBar v1.16

(with kind support of the author)

And this will not be the last you’ve seen of me.

Today I am presenting another small tool of mine: the ShutdownPlannerGUI

ShutdownPlannerGUI.zipShutdownPlannerGUI.zip Simple GUI for planned Shutdowns of MS Windows
[188 KB; MD5: 45cb64eef13ea47e98a7dcde0773e6f1; More Info]

The basic idea is simple: it is a small GUI, slapped together in C#, around the Shutdown command-line utility. It is about the timer, specifying when the system is going to shut down. The GUI provides several text boxes to conveniently enter the time in hours, minutes and seconds. And that is it.

The ESF-funded junior research group VICCI dealt from 2012 until the end of 2014 with the development, control and integration of cyber physical systems (CPS) at the Faculty of Computer Science of the Dresden University of Technology. The scope includes smart home environments and supporting people in the ambient assisted living.

My work package for visualization and visual analysis has within the project investigated three essential aspects and corresponding solutions:

  • visual analysis of complex, multi-dimensional, multimodal, dynamic space-time data,
  • visualization in heterogeneous, mobile and distributed IT infrastructure, and
  • implementation of visualization systems and components.

Today I am writing about the visual analysis of complex space-time data.

teaser

Visual analysis serves as administrative overview of a current CPS, mainly for security reasons, as assistance during development, and the operation of the system. Particularly interesting are out-of-the-ordinary (erroneous) behavior and the formation of emergent system properties. For this a visual exploration with minimal previous assumptions is necessary. For example, certain data, like forces acting upon joints of a robot arm, be visualized more effectively by representations in geometrical context. This assumption however reduced the generality of visualization.

I thus developed a corresponding visualization of data collected by the CPS using coordinated views of continuous-time scatter plots, continuous-time parallel coordinate plots and temporal heatmaps. This application is capable of interactive real-time representation of generic multi-dimensional data and offers the means for a visual analysis. The developed system was published in the journal Computer Graphics Forum, the leading European Journal on Visualization. In the context of the evaluation, live data from our laboratory CPS war visualized, presented and discussed with a broad audience.

Once again, it is time for one of my little tools, which the world does not need (but I do). The idea is simple: think of a series of files in one directory, e.g. music files of a audio book or video files of a TV series. Every once in a while you watch/listen to one of the files and days later you do not remember, which was the last file you have seen. My tool registers to the context menu of the Windows Explorer and provides a simply way of setting a bookmark at the file in the directory. The bookmark is an empty file with the same name, additionally using an extra file name extension). The whole thing is no shell extension, but a simple, normal DotNet application which writes to the right places in the registry. Simple, not elegant, but working.

Software should solve problems. Sometimes this is the case.

I had a problem:

I have a somewhat older convertible laptop, an ASUS Aspire 1820PT. A nice and cheap convertible of it’s time. With touch screen support for up to two fingers and with an acceptable computational power. I have upgraded it in the meantime with an SSD and I am now running Windows 8. So far so good. The problem, however, is that the tilt sensor is no longer supported by Windows 8. 🙁

So I needed a solution. Hacking drivers or even writing drivers myself is not up my alley. I am an application developer. But, if something does not work automatically (anymore), we just need to make the manual use as comfortable as possible. That’s why I wrote a tiny tool: the DisplayRotator.

The idea is simple: the tool is attached to the taskbar. As soon as it is started it shows DisplayRotatorScreena simple window with four buttons for the four possible display rotation settings. Press one of these buttons and the display settings are changed accordingly. With this, I can setup my desktop orientation of my convertible with two clicks, even two tapps with my finger, and rotate the desktop aynway I like.

And, because I can, the zip also contains the source code of the tool. It is written in C# and naturally uses the Windows API to change the display settings. Nice and easy. With the same code basis all display settings can be changes, like screen resolution and refresh rate. Even detaching or attaching monitors to the desktop is possible. Ok, the code for these functions is not in the tool, but the API calls are the same.

Maybe the tool can be of use to someone else too.

The last few weeks were packed with work. That’s why I had to distract myself and power down my brain a bit. So I tried something new and created three little fonts. Each only contains glyphs for the digits 1, 2, 3, 4, and 5 and represents them as tally marks. Since these files are simple and small, their are free for download and free for any use anyone would like:

I believe there are many people out there, which did not think this day would come. To all of those, I like to kick you in your shins, at least virtually. If I say I am doing something, then I will do it!

There is a newer Version of this File available
[129 KB; MD5: 7868fdb2a0f1c26d28cb88c618bf21e3; More Info]

Therefore, here it is: Mr. Burns TOK (Version 3.0)

Completely rewritten in C# for better maintainability and future bugfixing. Simply download and run (no Setup).
All you need is the Dotnet 2 Framework, which you most probably already have on your machine.
