Reaction Time Tester

I wrote this Silverlight app for my Cousin. The trickiest part was raising an event after a random amount of time for the "Wait..." portion of the test. I ended up using a "DispatcherTimer" and set the interval to a Random amount of seconds.




Have Fun!

How to Turn Off Microsoft Arc Touch Mouse Scroll Sound Vibration

Image
I recently purchased a Microsoft Arc Touch Mouse and wanted to turn off the middle button wheel scroll sound vibration.

It is possible, however perhaps not obvious.  First you need to download the "Mouse and Keyboard Center" executable available on this page http://www.microsoft.com/hardware/en-us/p/arc-touch-mouse#support.

(direct link Win8 x64: http://download.microsoft.com/download/F/4/7/F470FE38-7D5E-4BE2-BCA1-E333C28027A0/MouseKeyboardCenter_64bit_ENG_2.3.188.exe )


Run the executable and install the software.  After the software is installed, turn off "Vibration." See image below:




Hope this helps,

Hacker News Dataset October 2016

Our latest project on Sizzle is a visualization of the Top 10k Posts of All Time on Hacker News.



To create the visualization, we first needed to collect the data.

I noticed that there was an old copy of the hacker news dataset available on Big Query. But I needed an up-to-date copy, so I looked into the Hacker News Firebase API.

The API allows you to get each item by Id. You can start by retrieving the current Max ID, then walking backwards from there. (Items my be stories, comments, etc., it's the same API endpoints for all types of items.)

There is no rate limit, so I created the following script that will generate a text file with 10MM lines containing all of the URIs to retrieve. (we will then feed this file into wget using xargs)

Note: 10MM items was ~5 years worth of data.

That script takes about 10 minutes to produce a file that's around 560MB in…

VirtualBox Right-Click Windows Taskbar On Mac

Using VirtualBox on my Mac (in windowed mode, not full screen), I noticed that right-click on the Windows taskbar was not working. I commonly use right-click on the task bar to launch an application as administrator, pin an application to the taskbar, etc. I could two-finger click on other windows to get the right-click menu to appear, but that did not work on the taskbar.
To get the right-click menu to appear on the windows taskbar, I had to hold down the "host key" which for me was the left Mac command key, and single-finger click the item in the taskbar.

Hope this helps! Aaron
