Eye Tracking Project Notes

One of the main reasons I bought a 3d printer was to explore the idea of creating a headset with a medium to low end camera attached to it.  With a enough luck create a device that would work by tracking the eye. At the moment I'm putting this project on hold but I want to look at these resources later.

Angular: Custom Value Checkbox

Sometimes the dba won't change a field's datatype in the database which why handle all my databases now days. Just some quick notes for handling custom values to send back to the database for a form post. Using angular 1.5... <input type = "checkbox" ng-model = "item.selected" ng-true-value = "'TRUE'" ng-false-value = "'FALSE'" />  - " add quotations because it's an angularjs expression and it also needs to be a constant"  Resources http://plnkr.co/edit/ehXObXaXicC1BvKyQtmI?p=preview Angular view not updating when checkbox clicked Passing dynamic value with single quote as a ng-true-value expression fails

Don't Prompt for Permissions without the User's Direct Interaction

Image
For all the applications out there! Stop pushing for permissions and stop probing for information without reason. Regardless of your necessity for a feature a user is the right for not installing or using an app without clear intent. Action from the user are a direct link from the developer to the client for clear reason and intent on why they need permissions. I see this now and again with website using geo-location and never giving a reason on why the need the permissions but sure enough its the first prompt I get on their site...  This why I really like the recent changes with android its a little annoying for coding but the information needed for the user on why you need some information is clear. I always have to fight with project managers on whats initiate and I can be more direct on why I need something than from what you are asking me to do. There is still room for error (security issues) with a client if they still don't trust an application which I always say they can j

VS 2015 - The Operation Could not be Completed Invalid Pointer

This bug appears to happen in both visual studio 2015 and 2010 but I've only run into it for 2015. I'm not sure what I did to cause this other maybe moving around projects. I don't think that was the cause but I do sometimes delete the appdata folder. My solution for this bug is simple delete the AppData folder again (hahah).   I found from other sites that is the  ComponentModelCache folder  specifically that you want to delete. It goes without saying close all visual studio windows before doing this.   Folder Under: C:\Users\{YourUsername}\AppData\Local\Microsoft\VisualStudio\14.0\ ComponentModelCache

User-Agent Styled Web Applications

   This idea came from awhile back when I was working on my project rustkickers. The purpose of the site is to provide documentation on all things motor related. While working on a demo for the site used a old car manual to create some of the designs. That goes me thinking why not make multiple site designs around different car manufactures. Then even further down the rabbit I landed here, which is what this article. Another thought but a cool one I think and yes I know you can't trust the user-agent but it doesn't matter its just the style not the content.  Intial Solution Optimizing content for different browsers Filter based on webkit Chrome conditional comments Is there any equivalent to IE conditional comment for chrome and safari? IE10 CSS Hacks load webfonts through the offline storage cache manifest After playing around with this idea for awhile I figured handling this is the frontend at all was not worth it because of performance.

Fixing Chrome Settings - Windows Registry

Take a look at your policies! Always messing with things and there are three keys when it comes to chrome that need to be setup probably for you to enjoy the internet. Check them out either with "regedit" or chrome://policy/ Adding the correct Policies! “Sign in to Chrome” missing; No syncing options in chrome://settings Can’t update, can’t sync? no problem. just add these three keys, even if the Chrome key isn’t there just create it and add the children keys. HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Update\UpdateDefault HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome\SigninAllowed HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome\SyncDisabled @="0" Extra Registry Stuff (Windows 7) I didn't want to make another article on this stuff but had use for it. wallpaper-in-windows-7-locked-down-by-domain-group-policy HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer theme-allow-prevent-changing Carry ou

Jquery Plugin: Testing with (SauceLabs, Qunit, Travis-CI)

After looking around I found a project that worked great on desktop but not on so much mobile I figured I would fork it and figure out how I could improve. Build on Travis: https://travis-ci.org/fassetar/jquery-maskmoney Build on Sauce Labs: https://saucelabs.com/u/fassetar2 Since don’t need to write the tests I simply want to run the tests on multiple devices so I can see them fail on mobile. Using the  jquery-boiler as an example for creating the setup, I ran into multiple issues which I was able to correct as some heavy reading.

UI-Bootstrap Collapsible Sticky Footer

    I could have done this a lot of ways and ultimately I made it work with javascript modifying the class names. I also had to create multiple class names which I didn't like to much, I might come back and improve this but for now this is was I got. Also I call bootstrap+angularjs = ui-bootstrap, not sure if that's common sense but thought I should include it somewhere in my notes. Working Example: http://plnkr.co/edit/2N9ENlbw3bSvg1W9n0ch?p=preview This little css was key to prevent any kind of animation on the collapse, which would result in a scrollbar appearing on the body. A scrollbar can appear when the content's too long but not on the sticky foot duh! .no-animate { transition-duration: 0.0125s; } Research Angular-UI Bootstrap Collapse without animation - Stack Overflow http://jsfiddle.net/paulalexandru/Z2Lu5/  - Was looking at this to see if I could reuse it but I ended but just doing my own thing.

Installing Windows on Acer chromebook 15 cb3-532

Much of my notes are just small problems I faced (what's new!) haha. Either way this was a really fun project to do for a friend and I got excited once I research all the information. You can find instruction videos but what helped me the most was the coolstar website. Sadly they don't have parameters in the url so I can link the machine I used in this article. -  https://coolstar.org/chromebook/windows-install.html Scared of messing with the bios? Don't be!    So you need to first remove the screw to put a legacy bios on the machine. Its easy to backup the chrome os one and with the same steps to change it. You can go back in and revert to the chrome version bios. Its that last part that had me worried and its very easy to do.  Problems getting into Developer Mode?   Follow the instructions to the letter, during the step to disable the OS verification, press Ctrl-D to boot into os. If you hear two beeps I would go back to set one. I got in a loop where it s
