The picture above shows some research done by some UTD students for their UT Design program.
Their results showed the specs claimed by Xbee modules were far superior to reality. They said they experienced an overwhelming amount of noise at about half of the rated distance and both the peak and idle current ratings were inaccurate.
The following snippet of Jquery will prevent alerts from showing in internet explorer:
if ($.browser.msie) { window.alert = function() { }; };
It detects if the browser is IE, then disables the alert function with a blank if it is IE. The alert happens only in IE, that's why it checks to see if the browser is IE.
I did this because there is some code I can't change on a sharepoint page which is causing an alert (which doesn't actually cause any real issues). Adding this code to the part of the page I can change will stop the error.
About the alert: It says "Hit error fn!" and it happens in the following span after an ajax call fails: <span id="ctl00_LogUserActivity1">
I've been using SPJS charts to make google charts with data from sharepoint lists. If you use a custom drop-down filter, you may want to dynamically select items in the drop-down like I did.
An example: You're using a drop-filter which filters the results by week, but you always want it to select last week.
Snippet:
function manualLoad(){ loadManually = false; spjs_GenerateChart();
Date.prototype.getWeek = function() { var onejan = new Date(this.getFullYear(),0,1); var today = new Date(this.getFullYear(),this.getMonth(),this.getDate()); var dayOfYear = ((today - onejan + 1)/86400000); return Math.ceil(dayOfYear/7) };
The “Hackathon” was a programming competition sponsored by Ericsson to solve some of the North Texas Food Bank’s problems.
We made a scheduling system that allows people to see which days need more volunteers, then sign up to volunteer. The coolest part is that it would call people with a prerecorded message reminding them of their appointment.
It matches the number of weeks calculated in excel and all the calculators I could find on the internet.
Update: I also needed to add a 0 before the "Week" if the number is less than 10, because it will cause an error in sorting otherwise.
Here's the formula to add a 0 if the number is less than 10: =IF((INT((Date-DATE(YEAR(Date),1,6)+(TEXT(WEEKDAY(DATE(YEAR(Date),0,1)),"d")))/7)+1)<10,"0"&(INT((Date-DATE(YEAR(Date),1,6)+(TEXT(WEEKDAY(DATE(YEAR(Date),0,1)),"d")))/7)+1),(INT((Date-DATE(YEAR(Date),1,6)+(TEXT(WEEKDAY(DATE(YEAR(Date),0,1)),"d")))/7)+1))&" "
(Note: the &" " part forces it to be a string rather than a floating point value)
