• Find location of current m-file in Matlab

  - by Jordi

  I'm working on my Matlab code in a number of different locations and it would really help if I could make the code aware of its location on the computer. I think there is a function that gives me exactly this information, but I can't remember what it is called or find it on Google. The idea is that I have a function myFunc that needs a file in its own directory, which can be in different locations on different computers. So in myFunc I want to do something like this: dir = theFunctionImLookingFor; system(fullfile(dir, 'someApp.exe')); (it could also be that the function I'm looking for doesn't return the directory, but the directory + m-file name, but that makes little difference to me) Thanks for any help!

• Should I use "id" or "unique username"?

  - by roa3

  I am using PHP, AS3 and mysql. I have a website. A flash(as3) website. The flash website store the members' information in mysql database through php. In "members" table, i have "id" as the primary key and "username" as a unique field. Now my situation is: When flash want to display a member's profile. My questions: Should Flash pass the member "ID" or "username" to php to process the mysql query? Is there any different passing the "id" or "username"? Which one is more secure? Which one you recommend? I would like to optimize my website in terms of security and performance.

• jQuery .ajax request failing

  - by user1644808

  I currently have a jQuery ajax request set up like this $(document).ready( function() { $.ajax({ url : "http://www.my-computer.com:51000/getJson", cache : false, dataType: "json", success : renderPage, error: handleError }) }); If I manually naviate to http://www.my-computer.com:51000/getJson, I see it returns a json string correctly, but with the above request, I always fall into "handleError" method, with textStatus "error" and not much helpful information. Can anyone help? Thanks! EDIT: sorry about the my-computer domain. this stackoverflow submission won't let me input localhost, so I put in an arbitrary domain instead. I've tried firebug, but had no luck in getting the json back.

• mysql join with a "bounce" off a third table

  - by Enkay

  I have 3 mysql tables. companies with company_id and company_name products with product_id and company_id names with product_id, product_name and other info about the product I'm trying to output the product_name and the company_name in one query for a given product_id. Basically I need information from the names and companies tables and the link between them is the products table. How do I do a join that needs to "bounce" off a third table? Something like this but this obviously doesn't work : SELECT product_name, company_name FROM names LEFT OUTER JOIN companies ON (names.product_id = products.product_id and products.company_id = companies.company_id) WHERE product_id = '12345' Thanks!

• Care to be taken when serving static content (JS, CSS, Media) from different domain?

  - by Aahan Krish

  Let me try to explain by example. Say website is hosted at example.com (NOT www.example.com). In order to serve static content cookie-free, I've chosen to use a different domain example-static.com. Now, lets consider that my static content is currently served like this: http://example.com/js/script.js http://example.com/css/style.css http://example.com/media/image.jpg ** Now I create a CNAME record aliasing example-static.com to my main domain i.e. example.com so that the static content is served as such: http://example-static.com/js/script.js http://example-static.com/css/style.css http://example-static.com/media/image.jpg ** Is that all I have to do? Will all browsers execute JavaScript files and load web fonts without any security concerns? OR should I be using some .htaccess rules to modify header information and the like? PS: It would be great if you can provide what rules should be added, if need be.

• Weird behavior of curl and facebook

  - by monthon1

  Here is the code: $ch = curl_init( 'https://graph.facebook.com/btaylor'); curl_setopt( $ch, CURLOPT_USERAGENT, '' ); curl_setopt( $ch, CURLOPT_RETURNTRANSFER ,true); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); $data = curl_exec($ch); print_r( $data) ; curl_close($ch); It shows few informations from facebook. It works on my localhost, but when I try to run it on my server it just doesn't work, returns a blank site. I tried to use this code with others sites like example.com and It works, so I thought, that its becouse of facebook blocks my ip (i dont know why it would be true), so I checked it. I have run it with curl_setopt($ch, CURLOPT_PROXY, 'myproxy'); But it still doesn't show any information. I am trying to fix it all day, but its to difficult. Have you got some ideas?

• Processing variable number of form fields

  - by a_m0d

  I am working on a form which displays information about orders. Each order has a unique id, but they are not necessarily sequential on the form. Also, the number of fields can vary (one field per row on the form). The input into the form will not be mapped straight into the database, but will be added to the current value in the database, and then saved. An example of the form is in the picture below - the callout on the right shows the id for each row. I know how to generate the form like this, but I can't work out how I can easily process each of these rows reliably. I also know how to give each of the fields a unique identifier, like name="row-23", but how can I translate that name so that I can update the related record in the database?

  Suppose I have the following class. public class gen<T> { public gen(){ } Class<T> class(){ //something that figures out what T is. } } How can I implement the class() function without pass any additional information?

• Consolidating data in SharePoint from different sites based on variable site naming

  - by Mughrabi

  Hi, am working on a project where I want to pull data from different lists in SharePoint and have these data imported into a single list. The list has the same attribute everywhere; it is located in different sites. I have a list which contains all the site names and URL to those sites. The idea is to read from this list all the site names and then go to each one of those sites and try and pull the information from the list under that particular site, in synchronies matter. Data that are pulled from last week’s process do not need to be pulled again. Can someone guide me in explaining what would be the best way to doing this solution? Am using SharePoint 2007

• Effective Entity Update In Hibernate ?

  - by Tony

  I've always wanted to know How can I update an entity effectively in hibernate just as by using SQL. For example : I have a product entity , has a field name createTime , when I use session.saveOrUpdate(product) ; I have to get this field from database and then set to product then update , actually whenever I use session.saveOrUpdate() , I updated ALL fileds , even if I just need update only one field. but most time the value object we passed to DAO layer can't contain all fileds information , like the createDate in Product , we seldom need to update this field. How to just update selected fields ? Of course I can use HQL , but that will separate save and update logic . It would be better If Hibernate has a method like this : session.updateOnlyNotNullFields(product); How can I do this in Hibernate ?

• What are my options for streaming for silverlight?

  - by Will I Am

  I would like to implement limited scope streaming (LAN, multicast, even broadcast) where the client is implemented in silverlight. More importantly, I would like to stream from a desktop OS, not a server OS. As a result, I can't use the MS media server, which I believe requires WS2003 or WS2008. Ideally the solution would have some sort of API so I can plug in or provide a custom frame source. If I need to encode my own video, how can I encode using H.264 or another Silverlight supported codec? if I need to implement my own server, where can I find information about how a client starts to receive a stream? thank you! I know, it's a lot of questions, but it basically boils down to "how do I stream from a non-server OS?"

• Return a URI for local resource from a webservice

  - by peterkellyonline

  I want to design a webservice that returns a URI to a local resource on the webserver. What is the best (simplest) way to do this in C# using .asmx webservice? Or in other words - how can I get the URI for a physical file path in a webservice? Build a URI using the Uri class and the [WebService] namespace attribute? I know there is Server.MapPath(); that converts a virtual path into the corresponding physical path. I am looking for a way to do the opposite - having the physical path, I want to get not only the virtual path but the full URI. So if the webservice URI is http://some.server.com/services/example.asmx, the virtual path to the file I want to return is /Updates/file.xml and the physical path to that file is C:\Updates\file.xml what is the best way to get the URI http://some.server.com/updates/file.xml from that information? Thanks

• Sorting a value pair in Javascript

  - by Bradley M. Davis

  I must be missing the proper term or else I'm sure I could find the answer by searching... in any case, here's what I want to do. Through javascript, I get four variables (A, B, C, and D) that I would like to sort, and still keep track of the variable name (since it's encoded with meaning information). Sample Data: A = 2; B = 1; C = 4; D = 3; What I need to do now is sort them in value order (4,3,2,1) such that I can actually know the variable name ordering (C,D,A,B).

• Java long task - Did it stop writing to file?

  - by rockit

  I am writing a lot of data to a file, and while keeping my eye on the file it eventually stopped growing in size. Essentially my task is getting information from a database, and printing out all non-unique values in column A. Since there are many rows to the database table, and the database table is across my network, this is taking days to complete. Thus I'm concerned that since the file isn't growing, that it isn't actually writing to the file anymore. Which is odd, I have no "catch"'s in my code, so if there was a problem writing to file, wouldn't it have thrown an error?! Should I let the task complete (estimate 2-3 days from today), or is there something else that I don't know going on here making my application not write to the file?! my algorithm goes something like this Declare file Create new file Open file for writing get database connection get resultset from database for each row in the resultset - write column "A" to file - if row# % 100000 then write to screen "completed " + row# + " rows" when no more rows exist close file write to screen - "completed"

• Serving images from Amazon S3 in PHP application

  - by luckytaxi

  So it just occurred to me that once I upload profile pics to S3, I have to figure out a way to keep track of the files. For example, if "susan" uploads 3 profile pics, I need to recall those 3 pictures and display it on her profile page if someone views her page. With that said, would the following work? User uploads picture from form Save file information (filename, user info, etc...) into DB and reference URL from S3 Upload photos to S3 When displaying pictures, I'll query the DB for the info and display the images from S3 accordingly.

• user height and weight in sql

  - by Samuel

  We are planning to capture a user's height and weight and am looking for ideas on representing them in sql. I have the following questions in mind weight can be expressed in kilograms and grams and height in meters and centimeters, so should I capture them as a BigDecimal with an appropriate precision and scale or capture them as vanilla strings and do the manipulation in the user interface. Note: I am planning to capture the kilograms and grams separately in the user interface. should the metric of measurement be part of the sql (i.e. the end user might want to view this information in pounds, inches according to his preference) OR Should I just support kilograms / meters in the database and do the conversion while showing this in the user interface

• Filling a LOV in Oracle Apex based on data in another text box

  - by Martin Pugh

  I am fairly new to Oracle Apex, and have a problem. Our application currently has a method of entering data, with several text boxes and Optional List of Values. I would like to have an LOV based on information in another text box like so: select APPOINTMENT_ID PATIENT_ID from APPOINTMENT where PATIENT_ID = :P9_PAT_NUM where P9_PAT_NUM is a patient number in a text box. However, this would apparently only work if the text box has already been submitted, else it assumes the text box is null. Is there any way to get this working with an LOV, or perhaps some other method?

• Traffic consumed by Team Foundation Server 2010

  - by micha12

  We are currently selecting a source control and issue tracking software, and are looking towards Team Foundation Server 2010. Some participants of our project often have slow Internet connection (for example during travel), and therefore it is important for us to have a source control system that does not consume too much traffic. I was unable to find information on traffic consumption when using TFS 2010. Does anyone has such info? Does TFS 2010 support traffic compression? Do other source control systems (like SVN, for example) produce less or more traffic than TFS 2010?

• MySQL Join issue

  - by mouthpiec

  Hi, I have the following tables: --table sportactivity-- sport_activity_id, home_team_fk, away_team_fk, competition_id_fk, date, time (tuple example) - 1, 33, 41, 5, 2010-04-14, 05:40:00 --table teams-- team_id, team_name (tuple example) - 1, Algeria Now I have the following SQL statment that I use to extract Team A vs Team B SELECT sport_activity_id, T1.team_name AS TeamA, T2.team_name AS TeamB, DATE_FORMAT( DATE, '%d/%m/%Y' ) AS DATE, DATE_FORMAT( TIME, '%H:%i' ) AS TIME FROM sportactivity JOIN teams T1 ON home_team_fk = T1.team_id JOIN teams T2 ON ( away_team_fk = T2.team_id OR away_team_fk = '0' ) WHERE DATE( DATE ) >= CURDATE( ) ORDER BY DATE( DATE ) My problem is that when team B is empty, I am having irrelevant information .... it seems that it is returning all the combinations. I need a query that when team B is equal to 0, (this can occur in my scenario) I get only Team A - Team B (as 0) once.

• How do I remotely obtain a system's network shares and connections?

  - by Mick

  I'm looking for a way to obtain information similar to the following console applications, remotely: net use net share netstat -ano However, I need to be able to do this without running a 3rd party application on the system. This effectively rules out using psexec to execute the command remotely, because psexec would then be installed as a service. I should add that I have administrative credentials on the remote system. I've considered using WMI's remote execution ability, but that requires me to write output to a file and then retrieve it. It's possible, but I'd like to know if anyone has a better way. I am using Delphi 2010.

• android spectrum analysis of streaming input

  - by TheBeeKeeper

  for a school project I am trying to make an android application that, once started, will perform a spectrum analysis of live audio received from the microphone or a bluetooth headset. I know I should be using FFT, and have been looking at moonblink's open source audio analyzer ( http://code.google.com/p/moonblink/wiki/Audalyzer ) but am not familiar with android development, and his code is turning out to be too difficult for me to work with. So I suppose my questions are, are there any easier java based, or open source android apps that do spectrum analysis I can reference? Or is there any helpful information that can be given, such as; steps that need be taken to get the microphone input, put it into an fft algorithm, then display a graph of frequency and pitch over time from its output? Any help would be appreciated, thanks.
