    - by ross Hulford

There all lots of scalable bg images out there but none I can find that do this, any help would be appreciated.

  • JavaScript: How do I create an Array into another Array?

    - by Timnkd
    I have the following JavaScript Array: var jsonArray = { 'homes' : [ { "home_id":"203", "price":"925", "sqft":"1100", "num_of_beds":"2", "num_of_baths":"2.0", }, { "home_id":"59", "price":"1425", "sqft":"1900", "num_of_beds":"4", "num_of_baths":"2.5", }, // ... (more homes) ... ]} I want to convert this in an Array like such (pseudo code): var newArray = new Array(); newArray.push(home_id's); How can I do that? Notice how the newArray only has home_ids from the big jsonArray array.

  • Making firefox refresh images faster

    - by Earlz
    I have a thing I'm doing where I need a webpage to stream a series of images from the local client computer. I have a very simple run here: http://jsbin.com/idowi/34 The code is extremely simple setTimeout ( "refreshImage()", 100 ); function refreshImage(){ var date = new Date() var ticks = date.getTime() $('#image').attr('src','http://127.0.0.1:2723/signature?'+ticks.toString()); setTimeout ("refreshImage()", 100 ); } Basically I have a signature pad being used on the client machine. We want for the signature to show up in the web page and for them to see themselves signing it within the web page(the pad does not have an LCD to show it to them right there). So I setup a simple local HTTP server which grabs an image of what the current state of the signature pad looks like and it gets sent to the browser. This has no problems in any browser(tested in IE7, 8, and Chrome) but Firefox where it is extremely laggy and jumpy and doesn't keep with the 10 FPS rate. Does anyone have any ideas on how to fix this? I've tried creating very simple double buffering in javascript but that just made things worse. Also for a bit more information it seems that Firefox is executing the javascript at the correct framerate as on the server the requests are coming in at a constant speed. But the images are only refreshed inconsistently ranging from 5 times per second all the way down to 0 times per second(taking 2 seconds to do a refresh) Also I have tried using different image formats all with the same results. The formats I've tried include bitmaps, PNGs, and GIFs (GIFs caused a minor problem in Chrome with flicker though) Could it be possible that Firefox is somehow caching my images causing a slight lag? I send these headers though: Pragma-directive: no-cache Cache-directive: no-cache Cache-control: no-cache Pragma: no-cache Expires: 0

  • Collision free hash function for a specific data structure

    - by Max
    Is it possible to create collision free hash function for a data structure with specific properties. The datastructure is int[][][] It contains no duplicates The range of integers that are contained in it is defined. Let's say it's 0..1000, the maximal integer is definitely not greater than 10000. Big problem is that this hash function should also be very fast. Is there a way to create such a hash function? Maybe at run time depending on the integer range?

  • How can I visually format JSON data (programmatically)?

    - by Ian Robinson
    I'm working with big blobs of JSON. These blobs change slightly over time and a revision history is kept. I'd really like to be able to do a visual diff on them, but my problem is they're being stored without any formatting at all - everything is on one line, so that makes it a little hard to see what changed. Is there a good way to programatically format them ala http://jsonformat.com/ or http://jsonformatter.curiousconcept.com/?

  • Speeding up Math calculations in Java

    - by Simon
    I have a neural network written in Java which uses a sigmoid transfer function defined as follows: private static double sigmoid(double x) { return 1 / (1 + Math.exp(-x)); } and this is called many times during training and computation using the network. Is there any way of speeding this up? It's not that it's slow, it's just that it is used a lot, so a small optimisation here would be a big overall gain.

  • How to start x-axis labels(dates) from 0th position without using set_range(..)

    - by Rishi2686
    Hi there, First of all, I am really a newbie for flash charts. I have problem in using it. I am developing an app which gets values from database for chart. I have a line on chart, there are dates on x-axis starting from 0th position. I have dates 03-06-2010 and 05-06-2010 right now and may increase in future. When I set range of 1 month i.e 1st jun to 30th jun , it does not show lines but show values on y-axis. When I use range, i am not able to pass array of above two dates from database to chart, and viceversa. Here is my code-snippet can you give some hint. $x = new x_axis(); $x->set_range( mktime(0, 0, 0, 6, 1, date('Y')), // <-- min == 1st Jan, this year mktime(0, 0, 0, 6, 16, date('Y')) // <-- max == 31st Jan, this year ); $x->set_steps(86400); $labels = new x_axis_labels(); $labels->text('#date: jS, M Y#'); $labels->set_steps(86400); $labels->visible_steps(1); $labels->rotate(90); //$labels->set_labels($data_4); // date_4 is array of database values $x->set_labels($labels);

  • what is the most elegant way of showing first week in a month

    - by ooo
    In C#, i want to show the first week in a calendar (in a html table) and i am trying to figure out the most elegant algorithm to generate the right days. If the first day of the week is not Sunday, i want to show the days of preceding month (like you would see on a regular calendar). So, as an input you have a current month. In this case May. I want to generate this: Month: May <table> <tr> <th>S</th> <th>M</th> <th>T</th> <th>W</th> <th>TH</th> <th>F</th> <th>Sa</th> </tr> <tr> <td>25</td> <td>26</td> <td>27</td> <td>28</td> <td>29</td> <td>30</td> <td>1</td> </tr></table> so it should display something like this (ignore the alignment) S | M | T | W | Th | F | Sa | 25 - 26 - 27 - 28 - 29 - 30 - 1 given that each month would have the start of day be a different day of the week, i am trying to figure out an elegant way to get the values of this data using the DateTime object. I see it has a dayofweek property on a date. i am generating this table in C# on my server to pass down to a html page.

  • Is passing a struct value to a method by-reference in C# an acceptable optimization?

    - by Arc
    Say I have a struct: struct MyStruct { public int X public int Y } And a method in some class that is iterated over many times elsewhere: public bool MyMethod( MyStruct myStruct ) { return ... } Is changing the MyMethod signature to the following an acceptable optimization? public bool MyMethod( ref MyStruct myStruct ) If so, how much of an advantage would it really be? If not, about how many fields would a struct need for a big enough advantage using ref this way?

  • sortable list using jquery ui not passing updated list order

    - by Matthew Berman
    I am following the sortable lists railscast and got everything working except when I sort, the same (original) order gets passed to the update method each time, so it doesn't update the true order.

  • DateChooser is behaving strangely

    - by Tam
    I'm writing a Flex application and I came across what I think is a weird problem. I want to create a text box and a DateChooser as the datefield didn't do what I wanted and it's Halo so I can't skin it easily. I want the DateChooser to show when I click on the text input. Here is an except from my code: <s:TextInput id="wholeDate" width="100" mouseOver="stopChangeToNormal();" paddingRight="10" click="date1.visible = true" focusOut="date1.visible = false"/> <s:Button label="Go" width="70" /> </s:Panel> <mx:DateChooser id="date1" visible = "false" change="useDate(event);" mouseOver="changeToNormalState = false;" y="{wholeDate.y + buttonsGroup.y + 20}" x="{wholeDate.x + buttonsGroup.x - 175 }" /> The weird thing is that it works as I wanted if I make it visible = "true" to start but if I have it visible="false" it doesn't work! It shows but the date I select doesn't show in the box as it does if I have it as visible="true", but I don't want it to be visible initially. Any ideas?

  • Appropriate collection for variable-depth list?

    - by George R
    If I wanted to have a collection that described the (recursive) contents of a root directory, including directories and files, how would I store them? Or do I need to come up with an object that holds: -Current directory -Parent directory -Files in directory ..and slap them all in one big list and manually work out the relationship at runtime from each entries Parent directory.

  • Should I move this task to a message queue?

    - by Fedyashev Nikita
    I'm a big fan of using message queue systems(like Apache ActiveMQ) for the tasks which are rather slow and do not require instant feedback in User Interface. The question is: Should I use it for other tasks(which are pretty fast) and do not require instant feedback in User Interface? Or does it in involve another level of complexity without not so much benefits?

  • string in c++,question

    - by user189364
    Hi, I created a program in C++ that remove commas (') from a given integer. i.e. 2,00,00 would return 20000. I am not using any new space. Here is the program i created void removeCommas(string& str1,int len) { int j=0; for(int i=0;i<len;i++) { if(str1[i] == ',') continue; else { str1[j] =str1[i]; j++; } } str1[j] = '\0'; } void main() { string str1; getline(cin,str1); int i = str1.length(); removeCommas(str1,i); cout<<"the new string "<<str1<<endl; } Here is the result i get : Input : 2,000,00 String length =8 Output = 200000 0 Length = 8 My question is that why does it show the length has 8 in output and shows the rest of string when i did put a null character. It should show output as 200000 and length has 6.

  • Very Urgent :How to start a new session if a user click on the new tab in IE or mozilla on websphere

    - by ha22109
    Hi, I have one "user search" portlet on the home page of one application running on websphere portal server.Which display the matching user records as per the search criteria filled in the search form.I have requirement to have a "back to search input" link on the results page which onclick should show the filled form on the input jsp. The issue which i am facing is if i open the application in two diff tab of same IE browser and start giving some search criteria and submit and same time search for some other input from other IE tab (in the same browser)and then go back to previous tab and click on "back to search input" link then instead of showing me the first input it will show me the imput which i entered in the next IE tab. I am setting and getting the bean(form bean) through portlet session.but in the two diff tab of same IE it will be the sae user session (and may be the same portlet session..) Please tell me solution for this. The one thing to be notice here is i can access this "user search" application even without doing login also.so it must be taking the default portlet session in this case. what wil happen once i login and then search,will it going to overwrite the portlet session and http session or howz is that?

  • SQL code to display counts() of value retrieved from another column

    - by Doctor Trout
    I have three tables (these are the relevant columns): Table1 bookingid, person, role Table2 bookingid, projectid Table3 projectid, project, numberofrole1, numberofrole2 Table1.role can take two values: "role1" or "role2". What I want to do is to show which projects don't have the correct number of roles in Table1. The number of roles there there should be for each role is in Table3. For example, if Table1 contains these three rows: bookingid, person, role 7, Tim, role1 7, Bob, role1, 7, Charles, role2 and Table2 bookingid, projectid 7, 1 and Table3 projectid, project, numberofrole1, numberofrole2 1, Test1, 2, 2 I would like the results to show that there are not the correct number of role2s for project Test1. To be honest, something like this is a bit beyond my ability, so I'm open to suggestions on the best way to do this. I'm using sqlite and php (it's only a small project). I suppose I could do something with the php at the end once I've got my results, but I wondered if there was a better way to do it with sqlite. I started by doing something like this: SELECT project, COUNT(numberofrole1) as "Role" FROM Table1 JOIN Table2 USING (projectid) JOIN Table3 USING (bookingid) WHERE role="role1" GROUP BY project But I can't work out how to compare the value returned as "Role" with the value got from numberofrole1 Any help is gratefully received.
