Fireballs and ToolTips

So this probably my first none software related post ( /hurray?). Anyways I’m still learning and tinkering around with WordPress (will probably eventually change to a custom theme) and learning PHP.

You might have noticed I had just installed Now Reading Reloaded plugin, so that I can attempt to try and keep track of books I have read/reading. Will add the large list of books I have already read soon.

I have just finished reading Raymond E. Feist’s new book “Rides a Dread Legion”. Although not the best book he has written, it is still quite good (and I am pretty thankful he is still writing additional novels). I think the problem for me is that Pug&Party have just gotten so powerful that I am just surprised when something exists that can even be bothersome to them. This novel had introduced the new spell lore of Demonology; one of the key reasons for my enjoyment of the book. It was very interesting reading the experiences of someone who had through trial and error mastered the art vs. through studies.


What is people’s fascinations or rather intrinsic need to desire everything in a user interface to have a tooltip? I really value the information most tooltips provide however I think that there are a lot of applications (including the one I am developping on) that have gone to far to place a tooltip especially when it is unneeded.

Today I noticed one of the applications I have been using has tooltips for the “OK” & “Cancel” buttons, with the tooltips saying “OK” and “Cancel”as well.

This really brings up an issue taught in my User Interface course to build user interfaces under the assumption that every piece of software you will write can be assumed to be operated/used by someone who has the IQ of a shovel. Where has the idea of developping for power users’ disapeared to? I understand the benefits that developping for all users in an attempt to achieve a curb-cut phenomenon, however the choice to develop a lightweight/simple implementation designed for power users seems to be neglected.

Threads and Images

So trying to learn a bit about concurrent programming prior to my class next semester and thought a good way to learn would be to write a simple application. Kinda odd how simple apps seem to grow so quickly into something that is beyond my scope of knowledge.

I wanted to originally write a simple image manipulation tool, as I thought it would be neat to look into really basic manipulatoin and try and perform them on separate threads. I had initially thought of doing it somewhat similar to what I head learned in CS370 of breaking the image into smaller images and offloading the processing onto small threads. There seemed a pretty good class offered in the .NET framework for this sort of thing; the threadpool class.

However nothing turned out as I had expected and trying to use the threadPool class was nightmarish. I think partially the reason may be is that I am not setting up the image object properly so that multiple threads can access it. I guess the two approaches were either:

  1. Manipulate the actual image file and refresh the component with the new image every time a thread is done executing
  2. Manipulate the pixels that are actually being displayed.

Either or it didn’t seem to work.

Scaling Back

Decided to scale back my attempts and just decided to go for a 1 thread (backgroundworker) approach. I had succesffuly done grey scaling (which was neat to learn on how something so simple can actually be pretty intense if you want to make the greyscale perfect). I had chosen to use the values :

I then tried to put RGB sliders, however I seemed to have hit a wall in making the sliders feel really responsive. I guess I would appreciate help from anyone if they have any ideas on how to do it.

Here is the application with an image greyscaled.
