La publicité plus efficace sur l'iAd d'Apple que sur la télévision ? Oui d'après une étude de Nielsen

La publicité plus efficace sur l'iAd d'Apple que sur la télévision ? Oui d'après une étude de Nielsen Les annonces sur iAd (la plate-forme de publicité mobile d'Apple) seraient deux fois plus efficaces que celles diffusées sur les écrans de télévision. C'est en tout cas la conclusion d'une étude menée par le cabinet Nielsen sur une campagne publicitaire de cinq semaines pour les produits de la firme Campbell. L'étude aurait constaté que les personnes ayant vu l'annonce sur iAd étaient deux fois plus susceptibles de se rappeler le produit que celles qui l'ont vu sur un écran de télévision.

- by Nguyen Phi Vu

I have read many posts for installing Oracle Database 10g XE Server in Ubuntu, such as this But I get an error: E: Unable to locate package oracle-xe when execute the command sudo apt-get install oracle-xe At the previous step (sudo apt-get update), it also notices that E: Some index files failed to download. They have been ignored, or old ones used instead. Did any one meet and solve this problem? I have searched for this problem but got no proper answer.

Simple 2d game pathfinding

- by Kooi Nam Ng

So I was trying to implement a simple pathfinding on iOS and but the outcome seems less satisfactory than what I intended to achieve.The thing is units in games like Warcraft and Red Alert move in all direction whereas units in my case only move in at most 8 directions as these 8 directions direct to the next available node.What should I do in order to achieve the result as stated above?Shrink the tile size? The screenshot intended for illustration. Those rocks are the obstacles whereas the both ends of the green path are the starting and end of the path.The red line is the path that I want to achieve. http://i.stack.imgur.com/lr19c.jpg

2D pathfinding - finding smooth paths

- by Kooi Nam Ng

I was trying to implement a simple pathfinding, but the outcome is less satisfactory than what I intended to achieve. The thing is units in games like Starcraft 2 move in all directions whereas units in my case only move in at most 8 directions (Warcraft 1 style) as these 8 directions direct to next available nodes (they move from a tile to next neighboring tile). What should I do in order to achieve the result as in Starcraft 2? Shrink the tile size? On the picture you can see a horizontal line of rock tiles being obstacles, and the found path marked as green tiles. The red line is the path I want to achieve.

How to right align the search box [closed]

- by Hai Vu

I am a newbie in HTML, CSS. I am working on a simple web app using CherryPy and ran into the following problem. The page I serve has a h1 title and a form for search box. I would like to lay them out on the same line with the h1 left aligned and the form right align, like this: My H1 Title here [ ] Search But instead, I got them in two separate lines: My H1 Title here [ ] Search My HTML code: <span class="header"> <h1>${pagetitle}</h1> </span> <span class="searchbox"> <form> <input type="text" name="searchterm"> <input type="submit" value="Search"> </form> </span> My CSS: span.header { text-align: left; } span.searchbox { text-align: right; } I have tried to work around using table, but was told to use span to do the right thing. I appreciate your help to set it right.

Percentage calculation around 0.5 (0.4 = -20% and 0.6 = +20%)

- by Micheal

I'm in a strange situation where I have a value of 0.5 and I want to convert the values from 0.5 to 1 to be a percentage and from 0.5 to 0 to be a negative percentage. As it says in the title 0.4 should be -20%, 0.3 should be -40% and 0.1 should be -80%. I'm sure this is a simple problem, but my mind is just refusing to figure it out :) Can anyone help? :)

where should we place HIDDEN variable in JSP

- by micheal

I need to use Hidden variables in my JSP for session tracking. this is the code: <input type="hidden" name="REQ_TOKEN" value="<%=session.getAttribute("SESN_TOKEN").toString()%>" /> i am using this to compare the request token with session token, so only when both are equal i will evaluate that request otherwise i will throw an error. Now the problem is, when i place this code inside <form></form> tags, it is working fine. Unfortunately there are some JSPs in my application where we dont have tag(I know that sounds weird!). where can i place my code so that it will work? Cant i use Hidden variables without FORM tag???

hi all, we were maintaining an MS Access application. Person who actually developed the application used copyrighted code. Now we want to remove that code and re-write that logic. Problem is we dont know what is the copyrighted code and what is not.

Making a JQuery tooltip retrieve a new value every time the mouse moves.

- by Micheal Smith

As i am developing an application that makes use of a tooltip that will display a different value when the user moves the mouse. The user mouses over a table cell and the application then generates a number, the further right the cursor moves in the cell, the higher the value increases. I have created a tooltip that runs and when the cursor mouses over the cell, it does indeed show the correct value. But, when the i move the mouse, it does not show the new value but just the older one. I need to know how to make it update everytime the mouse moves or the value of a variable changes, Any ideas for the problem? <table> <tr id="mon_Section"> <td id="day_Title">Monday</td> <td id="mon_Row"></td> </tr> </table> Below is the document.ready function that calls my function: $(document).ready(function() { $("#mon_Row").mousemove(calculate_Time); }); Below is the function: <script type="text/javascript"> var mon_Pos = 0; var hour = 0; var minute = 0; var orig = 0; var myxpos = 0; function calculate_Time (event) { myxpos = event.pageX; myxpos = myxpos-194; if(myxpos<60) { orig = myxpos; $('#mon_Row').attr("title", orig); } if (myxpos>=60 && myxpos<120) { orig=myxpos; $('#mon_Row').attr("title", orig); } if (myxpos>=120 && myxpos<180) { orig=myxpos; $('#mon_Row').attr("title", orig); Inside the function is the code to generate the tooltip: $('#mon_Row').each(function() { $(this).qtip( { content: { text: false }, position: 'topRight', hide: { fixed: true // Make it fixed so it can be hovered over }, style: { padding: '5px 15px', // Give it some extra padding name: 'dark' // And style it with the preset dark theme } }); }); I know that a new value is being assigned to the cells title attribute because it will display inside the standard small tooltip that a browser will display. The JQuery tooltip will not grab the new value and display it, only the variables initial value when it was called.

php - comparing timestamp dates to make sure user is of minimum age

- by Micheal Ken

When a user signs up the system has to check that they are old enough to do so, in this example they have to be atleast 8 years old $minAge = strtotime(date("d")."-".date("m")."-".(date("Y")-8)); $dob = strtotime($day."-".$month."-".$year); $minAge = 01-03-2004, $dob = 01-02-2011 I basically need to make sure this person was born before 2004 but I want to know whether I have to convert the timestamps to do a comparison or whether there is a more efficient way. Any help is appreciated, thank you

Neural Network Inputs and Outputs to meaningful values

- by Micheal

I'm trying to determine how to transform my "meaningful input" into data for an Artificial Neural Network and how to turn the output into "meaningful output". The way I can always see of doing it is by convering everything to categories with binary values. For example, rather than outputting age, having a 0-1 for <10, a 0-1 for 10 - 19, etc. Same with the inputs, where I might be using for example, hair colour. Is the only way to turn this into input to have Blonde 0-1, Brown 0-1, etc? Am I missing some entire topic of ANNs? Most of the books and similar I read use theoretical examples.

What is the syntax for Dsynchronize "exclude filter" for files 's full path to exclude bin\* and obj\* of a C# solution?

- by Nam G. VU

Dsynchronize is a great free tool to sync two folders. I'm using it to sync two solutions checked out from two different TFS Team Collection. I want to exclude the following: All files in bin folder All files in obj folder I tried bin\*; obj\* but it doesn't work. How can I do that? ps. Though, trying *.g.* and *cache* help to exclude the files whose names match with the filter. It seems the filter is applied to the file name only NOT the full path of the file

TrueCrypt drive letter not available

- by Tono Nam

With c# or a batch file I mount a trueCrypt volume located at A:\volumeTrueCrypt.tc With c# I do: static void Main(string[] args) { var p = Process.Start( fileName:@"C:\Program Files\TrueCrypt\TrueCrypt.exe", arguments:@"/v a:\volumetruecrypt.tc /lw /a /p truecrypt" ); p.WaitForExit(); } the alternative is to run the command on the command line as: C:\Windows\system32>"C:\Program Files\TrueCrypt\TrueCrypt.exe" /v "a:\volumetruecrypt.tc" /lw /a /p truecrypt Either way I get the error: Why do I get that error? I was able to run that command the first time. The moment I dismounted the volume and tryied to mount it again I got that error. I know that drive letter W is available because it shows as an available letter on true crypt if I where to open it manually: If I where then click on the button mount and then type the password truecrypt (truecrypt is the password) then it will successfully mount on drive w. Why I am not able to mount it from the command line!? If I change the drive letter on the command line it works. I want to use the drive W though. In other words executing "C:\Program Files\TrueCrypt\TrueCrypt.exe" /v "a:\volumetruecrypt.tc" /lz /a /p truecrypt will successfully mount that volume on drive z but I do not want to mount it on drive z I want to mount it on drive w. The first time I ran the batch it ran fine. Also if I restart my computer I believe it should work. More info on how to use trueCrypt through the command line can be found at: http://www.truecrypt.org/docs/?s=command-line-usage Edit I was also investivating when does this error occures. In order to generate this error you need to follow this steps. 1) execute the command: (note the /q argument at the end for quiet) "C:\Program Files\TrueCrypt\TrueCrypt.exe" /v "a:\volumetruecrypt.tc" /ln /a /p truecrypt /q "C...TrueCrypt.exe" = location where trueCrypt is located /v "path" = location where volume is located /n = drive letter n /p truecrypt = password is "trueCrypt" /q = execute in quiet mode. do not show window note I am mounting to drive letter n 2) now volume should be mounted. 3) Open trueCrypt and manually dismount that volume (without using command line) 4) Attempt to run the same command line (without the /q so you see the error) "C:\Program Files\TrueCrypt\TrueCrypt.exe" /v "a:\volumetruecrypt.tc" /ln /a /p truecrypt 5) an error should show up So the problem ocures when I manually dismount the volume. If I dismount it from the command line I get no errors. But I think this is a bug from trueCrypt

How to change font/number/bullet format for the whole list

- by Nam Gi VU

Hi, Let's look at a sample word 2010 file here. In this file you can see that the first group of text has their indent modified. The 2nd, 3rd group keep their default format. I want to apply the changed I've made in the group 1st so group 2nd and 3rd and for the new group I'm going to add instead of recieving the default indent. How can I do that? ps. Currently what I have to do is quite boring: Copy group 1 and paste to create new group to get the formatted, then remove the old text, adding new text :(

How to transfer data between two netowks efficiently

- by Tono Nam

I will like to transfer files between two places over the internet. Right now I have a VPN and I am able to browse, download and transfer files. So my question is not really how to transfer the files; Instead, I will like to use the most efficient approach because the two places constantly share a lot of data. The reason why I want to get rid of the vpn is because it is two slow. Having high upload speed is very expensive/impossible on residential places so I will like to use a different approach. I was thinking about using programs such as http://www.dropbox.com . The problem with dropbox is it only enables 2 GB of storage in order for it to be free. I think the deals they offer are ok and I might be willing to pay to get that increase in speed. But I am concerned with the speed of transferring data. Dropbox will upload the file to their server then send it from the server to the other location. I will like it even faster lol. Anyways I was thinking why not create a program my self. This is the algorithm that I was thinking let me know if it sounds to crazy. (remember my goal is to transfer files as fastest as possible) Things that I will use in this algorithm: Server on the internet called S ( has fast download and upload speed. I pay to host a website and some services in there. I want to take advantage of it) Client A on location 1 Client B on location 2 So lets say on location 1 20 large files are created and need to be transferred to location 2. Client A compresses the files with the highest compression ratio possible. Client A starts sending data via UDP to client B. Because I am using UDP I will include the sequence number on each package. Have server S help speed up things. For example every time a package is lost we can use Server S to inform client A that it needs to resend a package. Anyways I think this approach will increase the transfer rate. I do not know if it is possible to start sending data meanwhile it is being compressed. Also if it is possible to start decompressing data even if we are not done receiving all the info. Maybe it will be faster to start sending the files right away without compressing. If I knew that I will always be sending large text files then I will obviously use the compression. I need this as a general algorithm. So i guess my question is should using UDP over TCP could increase performance by using an extra server to keep track of lost packages? and How should I compress files before sending? compressing a 1 GB file with the highest compression ration takes about 1 hour! I will like to take advantage of that time by sending it meanwhile it is compressed.
