• Twitter xAuth vs open source

  - by Yorirou

  Hi I am developing an open source desktop twitter client. I would like to take advantage on the new xAuth authentication method, however my app is open source which means that if I put the keys directly into the source file, it may be a vulnerability (am I correct? The twitter support guy told me). On the other hand, putting the key directly into a binary also doesn't make sense. I am writing my application in python, so if I just supply the pyc files, it is one more seconds to get the keys, thanks to the excellent reflection capatibilities of Python. If I create a small .so file with the keys, it is also trivial to obtain the key by looking at the raw binary (keys has fixed length and character set). What is your opinion? Is it really a secutiry hole to expose the API keys?

• How to return radio checked object with jQuery ?

  - by Kim

  HTML <input type="radio" name="rdName" id="uniqueID1" value="1" checked="checked"> <input type="radio" name="rdName" id="uniqueID2" value="2"> <input type="radio" name="rdName" id="uniqueID3" value="3"> jQuery #1 $('input:radio[name=rdName]:checked').val(); jQuery #2 $('input[name=rdName]:checked'); jQuery #1 gets the value of checked radio, but I need to get the whole object to get the ID. jQuery #2 get this (from Chrome Dev console). Object "0" is the actual object I need, but I am unable to just that. 0: HTMLInputElement constructor: function Object() context: HTMLDocument length: 1 prevObject: Object selector: input[name=rdName]:checked __proto__: Object Any ideas how to isolate the needed object ?

• Regex in Flex 3: How to Wrap Quotations Around a Dynamic String?

  - by Laxmidi

  Hi, I need some Regex help. I need to find beacon_ followed by an alphanumeric code and then wrap it in quotation marks. For something static, like the example, below it's straight forward. myReturn = myReturn.replace( 'id=beacon_80291ee9b3', 'id="beacon_80291ee9b3"'); But, my problem is that the part after beacon is a random alphanumeric code. (However, it is always the same length). For example, the beacon part could be: beacon_c8ac873136 beacon_dc83b5953e beacon_7a910d03d8 etc. The haystack that I'll search will look like: myReturn = "blah blah id=beacon_80291ee9b3 blah blah"; Thanks. -Laxmidi

• what database should i choose ?

  - by MemoryLeak

  I use winforms to develop a desktop application, and right now I plan to use SQL server express, but the problem is, if i use sql server express, then the installation is much trouble, i need to install sql server first, and install my own applicaiton. Then I tried to use access 2003 as my database, then I only need to copy the mdb file with my application. But the access 's function is not that strong, the text length is limited to 255 byte. Is there any other database solution, which is easy to integrate to my application, and easy to install after i develop my application ? Many many desktop application have their own database, and easy to install and easy to use, what database do they use ?

• Hibernate @Index on @Enumerated field doesn't work

  - by mlaverd

  I am using Hibernate to talk to my DB. I have one field that is an enumeration and it is going to be used in a slow query. So I'd like to index it. I've put the following annotations on the field: @Column(name="RIGHT_TYPE", unique=false, nullable=false, length=10) @Enumerated(EnumType.STRING) @Index(name = "ABC_INDEX") protected RightType rightType; However, I don't see any index on that field created. But I can create one manually if I wish so. Why is that? Is there any way to force Hibernate to make it happen?

  - by Bernie Perez

  I am trying to benchmark some code. I am sending a String msg over sockets. I want to send 100KB, 2MB, and 10MB String variables. Is there an easy way to create a variable of these sizes? Currently I am doing this. private static String createDataSize(int msgSize) { String data = "a"; while(data.length() < (msgSize*1024)-6) { data += "a"; } return data; } But this takes a very long time. Is there a better way?

  I have added a install for Silver light to my MDT server, so it can get installed when the image gets deployed. When I boot them machines it is asking me to install the applications, how can i get it to auto install the apps without prompting.

• Manually closing a port from commandline

  - by codingfreak

  Hi I want to close an open port which is in listening mode between my client and server application. Is there any manual command line option in Linux to close a port ?? NOTE: I came to know that "only the application which owns the connected socket should close it, which will happen when the application terminates." I dont understand why it is only possible by the application which opens it ... But still eager to know if there is any another way to do it ??

• Test for empty jQuery selection result

  - by fsb

  Say I do var s = $('#something'); and next I want to test if jQuery found #something, i.e. I want to test if s is empty. I could use my trusty isempty() on it: function isempty(o) { for ( var i in o ) return false; return true; } Or since jQuery objects are arrays, I suppose I could test s.length. But neither seem quite in the idiom of jQuery, not very jQueryesque. What do you suggest?

• Enable Datepicker only when first field has a value

  - by Syed Abdul Rahman

  Right now, the End Date selection is disabled. I want to only enable this when a Start Date is selected. if( $('#datepicker1').val().length === 0) { $('#datepicker2').datepicker("disable"); } else { $('#datepicker2').datepicker("enable"); } This clearly does not work. If I insert value = 'random date' into my first input field, it works fine. I'm not too sure on how do this. Clearly not as easy as I had hoped. My other problem, or hope, is to disable the dates including and before the first selection. You know, pick Start Date, and every date before and said date for the next picker would be disabled. But that is a whole other problem.

• Can you create ACLs with open vSwitch on XenServer 5.6FP1 without using the DVS appliance?

  - by bwizzy

  I have a pool of XenServer hosts running the Free version of XenServer 5.6 FP1. I was wondering if I change the network backend to use Open vSwitch if I can specify ACLs on individual network VIFs without needing to use the DVS appliance (distributed virtual switch) which requires an Advanced License or higher. Basically I'm looking for a way to isolate VMs on my network so that if a user had root access on the command line they couldn't access other servers they should not be able to (without using a VLAN).

• script to su with password in script without root

  - by Triplell89

  I have scripted a process that involves updating symbolic links on files located on 3 different machines. On those machines exists 4 users each, who each need to have these links updated. Using su, is there a way to pass the password argument to the command on a single line, without invoking sudo as the users will not have admin rights? My only alternative solution at this point is to ssh around, however I would like to be able to do this without hardcoding in a bunch of hosts/ips.

• Convert void* representation of a dword to wstring

  - by graham.reeds

  I am having dumb monday so my apologies for posting such a newbie-like question. I am using CRegKey.QueryValue to return a dword value from the registry. QueryValue writes the value into void* pData and the length into ULONG* pnBytes. Now there is a way of getting it from pData into a wstring probably via stringstream. The closest I came was getting the result as a hex string. I was about to work on converting the hex representation to a dword and then from there to a wstring when I decided that was just dumb and ask on here instead of wasting another hour of my life on the problem.

• Mount Windows share on Linux boot

  - by Delameko

  I'm running VirtualBox in Windows. I have Linux 10.04 installed as a VM. Whenever I log in I have to run to following command to mount my shared Windows web dev folder: sudo mount.vboxsf web_apps /mnt/web_apps Where can I put this line (minus the sudo) so that it will run once when Linux boots up? I'm guessing there must be a root .profile or .login script that runs at some point?

• Reading files from an embedded ZIP archive

  - by aix

  I have a ZIP archive that's embedded inside a larger file. I know the archive's starting offset within the larger file and its length. Are there any Java libraries that would enable me to directly read the files contained within the archive? I am thinking along the lines of ZipFile.getInputStream(). Unfortunately, ZipFile doesn't work for this use case since its constructors require a standalone ZIP file. For performance reasons, I cannot copy the ZIP achive into a separate file before opening it. edit: Just to be clear, I do have random access to the file.
