• Help Auditing in Oracle

  - by enrique

  Hello everybody I need some help in auditing in Oracle. We have a database with many tables and we want to be able to audit every change made to any table in any field. So the things we want to have in this audit are: user who modified time of change occurred old value and new value so we started creating the trigger which was supposed to perform the audit for any table but then had issues... As I mentioned before we have so many tables and we cannot go creating a trigger per each table. So the idea is creating a master trigger that can behaves dynamically for any table that fires the trigger. I was trying to do it but no lucky at all....it seems that Oracle restricts the trigger environment just for a table which is declared by code and not dynamically like we want to do. Do you have any idea on how to do this or any other advice for solving this issue? thanks in advance.

• What's the easiest way to use OAuth with ActiveResource?

  - by Barry Hess

  I'm working with some old code and using ActiveResource for a very basic Twitter integration. I'd like to touch the app code as little as possible and just bring OAuth in while still using ActiveResource. Unfortunately I'm finding no easy way to do this. I did run into the oauth-active-resource gem, but it's not exactly documented and it appears to be designed for creating full-on API wrapper libraries. As you can imagine, I'd like to avoid creating a whole Twitter ActiveResource API wrapper for this one legacy change. Any success stories out there? In my instance, it might be quicker to just leave ActiveResource rather than get this working. I'm happy to be proven wrong!

• iphone: mechanical drawing & layers

  - by d_CFO

  I need to do a bit of mechanical drawing. I can (1) display the part’s image, [self.view addSubview:thePartAsImageView]; (2) implement two sliders (one horizontal for part’s width and one vertical for part’s height), heightSlider.transform = CGAffineTransformRotate(heightSlider.transform, 270.0/180*M_PI); (3) display the corresponding values (dimensions) as the user moves the sliders, and even (4) draw the dimensioning lines with arrowheads: CGContextAddLineToPoint What I can’t do is (5) remove those lines after I’ve drawn them. What I want is “if userTouchedTheHorizontalControl then eraseTheLinesForTheVerticalControl.” If I understand correctly – first, that Quartz composites everything to a single layer, and second, that CALayer, GeekGameBoard and so on only work on Mac -- then I have to do something different. But isn’t there something I can do other than switch to Open GL?

• AdMob Android integration - what permissions to ask for?

  - by AngryHacker

  In the various videos on the AdMob integration, I've seen that only permission to access the internet is asked for: <uses-permission android:name="android.permission.INTERNET" /> Not that I am an expert in advertising, but wouldn't AdMob need the user's geographic location as well, so that they can serve location specific ads? Or avoid serving certain ads based on a location, like maybe not offering me a Big Mac if I am in India or not adverting a ham sandwich if I am in an Arab country? If AdMob needs those permissions, how do I ask for them?

• capistrano put() and upload() both failing

  - by Kyle

  With capistrano, I am deploying a Rails application from Mac OS X 10.5 to CentOS 5.2 Note that deploy.rb and the server environment have not changed in over a year. There is a task within our deploy.rb file called upload: put(File.read( file ),"#{shared_path}/#{filename}", :via => :scp) This fails each and every time with the following exception: No such file or directory - /srv/ourapp/releases/20100104194410/config/database.yml My local copy of config/database.yml is failing to upload properly. I've verified it's not our internet connection, as this happens on three different connections and two different systems. I've also tried to swap out put() for upload() but get the same result; also, dropping :via = :scp, and/or trying to force :sftp instead similarly fails. Relevant info: $ cap -V Capistrano v2.5.10 $ ruby -v ruby 1.8.7 (2008-08-11 patchlevel 72) [i686-darwin9.6.0]

• advice on setting up SVN

  - by Vivek Chandraprakash

  I'm trying to setup an svn server. I maintain couple of websites based on asp. There are three environments currently. Development: Any new modules/enhancements will be done in this environment Staging: Mirror of production Production: The public facing website. Currently when there's an update to the website, this is what we do do the update in development copy file to staging copy file to production In production we take a backup of the old file by renaming it. I would like to make it simpler by installing SVN and stop the file renaming thing. But im not sure how many repositories to have per website. should be it be three or two? I'm absolutely new to svn. Just installed it in a linux based server (ubuntu). Can you pls advice how to go about it? Thanks -Vivek

• How did Perl gain a reputation for being a write-only language?

  - by Andrew Grimm

  How did Perl gain a reputation (deserved, undeserved, or used to be deserved, no longer so) of being a "write only language"? Was it The syntax of the language Specific features that were available in the language Specific features not being available in the language (or at least old versions of it) The kind of tasks Perl was being used for The kind of people who use Perl (people who aren't full-time programmers) Criticism from people committed to another language Something else? Background: I'd like to know if some aspects that gave Perl the reputation of being write-only also apply to other languages (specifically ruby). Disclaimer: I recognise that Perl doesn't force people to do write-only code (can any language?), and that you can write bad code in any language.

  - by Mambley

  Hello, I am trying to code and style a box which will contain a post.

If you please check the following url, you can check what i need to accomplish. http://dl.dropbox.com/u/3696224/postBox.jpg If you notice it has: one border around all the box with a dark gray (#cccccc); (border) a small space between that border and other light gray (#f7f7f7), almost white; and only then the content with a white background; Any suggestions? Very sorry for English grammar, thanks in advance. Regards PS - I almost forgot, i don't know is if needed or not, but the all around the box i have a box-shadow (i know how to do this part)

• Tripple-wrapping fails: \colorbox ? \NewEnviron ? \newenvironment fails

  - by o_O Tync

  Hello! I am trying to wrap an environment created with \NewEnviron (package 'environ') into an old good \newenvironment: \NewEnviron{test}{\colorbox[gray]{0.7}{\BODY}} \newenvironment{wrapper}{\begin{test}}{\end{test}} \begin{wrapper} debug me \end{wrapper} However, this gives me a strange error: LaTeX Error: \begin{test} on input line 15 ended by \end{wrapper}. LaTeX Error: \begin{wrapper} on input line 15 ended by \end{document}. If I replace \NewEnviron{test}{aaa(\BODY)bbb} with \newenvironment{test}{aaa(}{)bbb} — everything works as expected! It seems like \NewEnviron fails to find its end for some reason. I'm trying to do some magic with 'floatfig' wrapped into a \colorbox so I need a way to convert \colorbox to an environment and wrap it into another one. I can define a new command but it's not a very good idea. Thanks in advance!

• Good learning resources for JNDI implementation (JBoss 5)

  - by iandisme

  I have been working with JavaEE/EJB3 web apps for about half a year now. Until recently, I haven't had to touch a lot of the behind-the-scenes stuff, just the meat of the code. I have been wrestling with JNDI problems, and though I've solved a couple of them, I'm pretty much just doing the whole cargo cult copy-paste routine. It would really help me to better understand JNDI; my understanding of it right now can be summarized as "it's that thing these classes sometimes do to find other classes." My question is, has anyone had success learning JNDI/EJB3/related topics from a book or online content? I've googled for it but the stuff that comes up is old or specific to a certain framework I'm not using. I'm looking for something that's either JBoss-specific or generic enough to be useful anyway.

• WPF Application - Role Management Recommendations

  - by David Ward

  I have a WPF application with a WCF service layer and a SQL database. I now want to restrict elements of the application so that certain functions are only available to those users with a particular role. For example, you will only be able to navigate to the settings screen if you are an administrator. I would like a user to be a member of 1 or more authorisation groups and each authorisation group to have 1 or more roles associated. A long time ago I used AzMan (Authorisation Manager) to do a similar thing. Does anyone think that there are better approaches? Is AzMan "old news"? Alternatives? Thanks.

• is it possible to lock oracle 10g database table with C#/(ADO?).NET 2.0

  I have a table that contains a maximum value that needs to be get and set by multiple programs. How can I lock the table for a while when old value is got and new is updated in C#? In other words: string sql = "lock table MaxValueTable in exclusive mode"; using (DbCommand cmd = cnctn.CreateCommand()) { cmd.CommandText = sql; // execute command somehow!! } maxValue = GetMaxValue(); SetMaxValue(maxValue + X); sql = "lock table MaxValueTable in share mode"; using (DbCommand cmd = cnctn.CreateCommand()) { cmd.CommandText = sql; // execute command somehow!! } -BR: Matti

• Unable to add Solution to TFS 2010 due to existing (invisible)binding

  - by Refracted Paladin

  I have a smallish utility library I made that I had created in TFS Beta 2 to test out TFS. I now have TFS rc1 installed(and Beta 2 uninstalled) and am trying to add my Solution to TFS. I get an error saying that it is already bound to my old TFS, which was on a different system then this one. Strangely, when I go into Source Control and look at the bindings it says there aren't any. Also, I manually deleted the .vss and .vsc files and it still does it. Ideas? I looked through the numerous other SO topics related to this but unless I missed one none of them are dealing with my issue. Ideas?

• Pyparsing CSV string with random quotes

  - by gtfx

  Hey, I have a string like the following: <118date=2010-05-09,time=16:41:27,device_id=FE-2KA3F09000049,log_id=0400147717,log_part=00,type=statistics,subtype=n/a,pri=information,session_id=o49CedRc021772,from="[email protected]",mailer="mta",client_name="example.org,[194.177.17.24]",resolved=OK,to="[email protected]",direction="in",message_length=6832079,virus="",disposition="Accept",classifier="Not,Spam",subject="=?windows-1255?B?Rlc6IEZ3OiDg5fDp5fog+fno5fog7Pf46eHp7S3u4+Tp7SE=?=" I tried using CSV module and it didn't fit, cause i haven't found a way to ignore what's quoted. Pyparsing looked like a better answer but i haven't found a way to declare all the grammars. Currently, i am using my old Perl script to parse it, but i want this written in Python. if you need my Perl snippet i will be glad to provide it. Any help is appreciated.

• Password reset by email without a database table

  - by jpatokal

  The normal flow for resetting a user's password by mail is this: Generate a random string and store it in a database table Email string to user User clicks on link containing string String is validated against database; if it matches, user's pw is reset However, maintaining a table and expiring old strings etc seems like a bit of an unnecessary hassle. Are there any obvious flaws in this alternative approach? Generate a MD5 hash of the user's existing password Email hash string to user User clicks on link containing string String is validated by hashing existing pw again; if it matches, user's pw is reset Note that the user's password is already stored in a hashed and salted form, and I'm just hashing it once more to get a unique but repeatable string. And yes, there is one obvious "flaw": the reset link thus generated will not expire until the user changes their password (clicks the link). I don't really see why this would be a problem though -- if the mailbox is compromised, the user is screwed anyway.

• Mono - Uri class

  - by Jonathan.Peppers

  I am making an HttpWebRequest at a url similar to this: "http://mysite.com/search?query=my+search+string" Problem is, the Uri class escapes it with %, and the site I'm making the request against can't handle the escaped characters. (I have no control to fix the site) So tried this [Obsolete] constructor: new Uri(myUriString, true); But it did not seem to make any difference, when debugging, my Uri still got escaped. I am running this on a Mac with Mono, but I have not tried it on standard .Net on Windows to see if it has the same behavior. Is there another way to get around this issue?

• How to not check in Eclipse specific project files?

  - by futlib

  I don't want to force people into using a specific IDE for development, so our projects look basically like this: SomeProject src lib build.xml No IDE specific files whatsoever. However, many people prefer Eclipse and it is their valid complain that it is annoyingly difficult to set up an Eclipse project from an Ant build file if that project is checked into a VCS. That's a very old bug, so I don't really expect it to be fixed soon. I don't want all those weird Eclipse project files in the project root, but if it was the only way, I would accept having the eclipse project files in a subdirectory "eclipse". I thought Eclipse's linked resources were capable of just that, but I was wrong, it doesn't really work. How do you solve this problem? Are you checking in the .settings directory. etc. into your project's root?

• Does mod_rewrite in subdirectories' .htaccess override higher levels?

  - by Ryan

  I'm using mod_rewrite to map my old directory structure to a new one. I have the following rule in my top-level .htaccess file, and it works: RewriteEngine On RewriteCond %{REQUEST_URI} /blog/archives/(.*) RewriteRule ^.*$ /archives/%1 [L,R=301] As you can guess, this takes http://example.com/blog/archives/00001.php and redirects it to http://example.com/archives/00001.php. But when I add these rewrite rules to the .htaccess file in the /blog directory RewriteEngine on RewriteRule atom.xml$ /atom.xml [L,R=301] the top-level redirect no longer works. If I move the rule in the /blog .htaccess file to the top-levle file both rules work. Can someone explain what is happening here?

• svn hangs when connecting to server but only for me!

  - by vgm64

  I've checked out two repositories with svn and they both have some odd behavior when using commands like svn -u status. That command in particular will hang, and top says the process is sleeping. I can check out and update those repos (usually), but this in particular will hang until I kill -9 it. It doesn't happen on anyone else's computer (I'm running Mac OSX 10.6) who uses these repos. I just checked out a fresh clean version of one of the repos, and did svn -u status and it froze. Anyone have any thoughts? Could some settings be corrupted?

• Find missing birth days in Apple Addressbook

  - by Felix Ogg

  I am trying to clean the holes out of my Mac address book. As a first step I want to ask all my friends for their birth day, to be able to congratulate them with cheesy Hallmark cards. I need a "group" in my address book, to mailmerge personalized messages from. This is the Applescript I came up with: tell application "Address Book" make new group with properties {name:"No Birthday"} set birthdayPeople to (get every person whose birth date is greater than date "Monday, January 1, 1900 12:00:00 AM") repeat with i from 1 to number of items in people set thePerson to item i of people if not (birthdayPeople contains thePerson) then add thePerson to group "No Birthday" end if end repeat save end tell It breaks, but from the error messages I cannot deduce what is wrong: Result: error "Can’t make «class azf4» id \"05F770BA-7492-436B-9B58-E24F494702F8:ABPerson\" of application \"Address Book\" into type vector." number -1700 from «class azf4» id "05F770BA-7492-436B-9B58-E24F494702F8:ABPerson" to vector (BTW: Did I mention this is my first AppleScript code, EVER? So, if this code can be simplified, or made more elegant, that is welcome too.)

• Is it actually possible to connect to ActiveMQ via XMPP and query/browse queues using "AciveMQ.Agen

  - by Oleg Kiorsak

  I tried what I think are 4 most popular XMPP (aka "Jabber") clients (Spark, Pidgin, Psi, Pandion) to connect to ActiveMQ instance (Apache ActiveMQ ver. 5.3.0) on XMMP connector with an idea to use the "AciveMQ.Agent chatroom" for querying queues/etc and no success at all Some of them fail with 'Unknown error', some don't fail but kind of "hang"... interestingly, some communication does indeed reach the ActiveMQ side, because when I close a client it spits an exception "could not close" or something to that effect... and if I try "register new user" option (present on most clients" the ActiveMQ also spits some most cryptic warning message But I was never able to get to the point when I could see or specify "ActiveMQ.Agent" as chatroom and issue any commands... Before I waste any more time on this curious feature, I would like to hear whether anyone had any success with it? Thank you! PS: BTW, the book "ActiveMQ in Action book" http://www.manning.com/snyder/ shows that it is apparently works and is very easy using some Mac client (AdiumX), but I wanted it on a Windows PC ;)

• FileReference and HttpService Browse Image Modify it then Upload it

  - by user177787

  Hello, I am trying to do an image uploader, user can: - browse local file with button.browse - select one and save it as a FileReference. - then we do FileReference.load() then bind the data to our image control. - after we make a rotation on it and change the data of image. - and to finish we upload it to a server. To change the data of image i get the matrix of the displayed image and transform it then i re-use the new matrix and bind it to my old image: private function TurnImage():void { //Turn it var m:Matrix = _img.transform.matrix; rotateImage(m); _img.transform.matrix = m; } Now the mater is that i really don't know how to send the data as a file to my server cause its not stored in the FileReference and data inside FileReference is readOnly so we can't change it or create a new, so i can't use .upload();. Then i tried HttpService.send but i can't figure out how you send a file and not a mxml.

• subversion merge back to trunk

  - by Berryl

  I set up a branch several weeks ago. When some changes were made to the trunk, SVN was committing to the branch, and not the trunk. The changes were minor and applicable to the branch anyway, so I assumed this is how the branch should work. Now that the branch work is finished, I merged back the branch back to my working trunk, assuming SVN would replace the old trunk with the new branch in the repository as well. That is not the case though. My repository trunk is out of date. I would like to make the repository trunk be same as the branch and then delete the branch. How can I do this? Cheers, Berryl Note: I am using tortoise / visualvsn client.
