• What is the best practise for relational database tables in mysql?

  - by George

  Hi, I know, there is a lot of info on mysql out there. But I was not really able to find an answer to this specific and actually simple question: Let's say I have two tables: USERS (with many fields, e.g. name, street, email, etc.) and GROUPS (also with many fields) The relation is (I guess?) 1:n, that is ONE user can be a member of MANY groups. What I dis, is create another table, named USERS_GROUPS_REL. This table has only two fields: us_id (unique key of table USERS) and gr_id (unique key of table GROUPS) In PHP I do a query with join. Is this "best practice" or is there a better way? Thankful for any hint!

• Advanced Registry Monitoring

  - by RyanTimmons91

  I'm attempting to create a small utility to watch for the creation (or modification) of a specific registry key, and to kill the process responsible for causing that registry modification. I have had success in watching the changes to the registry via a class called 'RegistryMonitor', however it does not give you any information on what process initiated the registry call, through some googling I found that a library called 'EasyHook' should be able to do what I want, but all the documentation states that its designed for a per-application hook. The program itself is a temporary security patch, until our vendors come out with an official security update. As best I can tell there isn't a way to do exactly what I want to accomplish from C#, which is the only language I can comfortable write, test and execute software in. Any help on this would be appreciated I'm considering watching the registry changes via the program I already have, then if the change is discovered (the pc is already infected) running RKill and locking down the PC to prevent the issue from getting any worse

• ActionScript - One Button Limit (Exclusive Touch) For Mobile Devices?

  - by TheDarkIn1978

  two years ago, when i was developing an application for the iPhone, i used the following built-in system method on all of my buttons: [button setExclusiveTouch:YES]; essentially, if you had many buttons on screen, this method insured that the application wouldn't be permitted do crazy things when several button events firing at the same time. problematic: ButtonA and ButtonB are available. each button has a mouse up event which fire a specific reorganization/layout of the UI. if both button's events are fired at the same time, their events will likely conflict, causing a strange new layout, perhaps a runtime error. solution: application buttons cancel any current pending mouse up events when said button enters mouse down. private function mouseDownEventHandler(evt:MouseEvent):void { //if other buttons are currently in a mouse down state ready to fire //a mouse up event, cancel them all here. } of course it's simple to manually handle this if there are only a few buttons on stage, but managing buttons becomes more and more complicated / bug-prone if there are several / many buttons available. is there a convenience method available in AIR specifically for this functionality?

• Change URL of a saved HTML file

  - by Paul Camilleri

  I am new to HTML so this question might sound a bit lame. Anyways I have a saved webpage on my desktop that when i open it in google chrome i want it to show a specific URL instead of its current location. Any ideas how i might get this to work? I tried using the history.pushState but i have no idea why it is not working. I created a simple page for now to test it: <html> <head> <script> function setURL() { history.pushState("Test","page2", "www.test.com"); } </script> </head> <body> <button type="button" onclick="setURL()">Set Url</button> </body> </html> Any help would be greatly appreciated. Thank you

It'll contain both characters with int or decimal numbers eg A12B32.25C-456D-75.E75 I'll know that this will start with A and ends with E I think I can use "^" and "$" right? but i'm bit lost in other parts to check for character and int or decimal.

• Django: Is it possible to attach media files (css, javascript etc) to a View-class?

  - by mrmclovin

  I can't fins any information on how to define css or javascript files in a view like: class MyView(View): .... class Media: css = { 'all' : 'mystyle.css' } If you have a form you can do like: class MyForm(ModelForm): .... class Media: css = { 'all' : 'mystyle.css' } And then in the template you can print the files like; {{ form.media.css }} I like that Syntax very much and I like to keep the View-specific css files in the app-directory. Does anyone know if it's possible? Thanks!

• Rails: updating an item along with associated items

  - by shmichael

  Suppose I have a simple to-do list application. The application contains two models: lists (have an owner and description) items (have name and due-date) that belong to a specific list I would like to have a single edit screen for a list in which I update the list attributes (such as description) and also create/delete/modify associated items. There should be a single "save" button that will commit all changes. Unless save is pressed, any change to the list and the items should be forgotten. I wasn't able to find an elegant best practice for this. Would greatly appreciate any suggestions and/or references to existing implementations.

• Entering If Statement Despite Not Meeting Condition

  - by msmf14

  This is a specific problem, but I can't seem to figure out what is wrong. else if (X == 2) //move left { if (Level[X-1][Y] == 0); { cout << Level[X-1][Y] << "\n"; cout << "\n MOVING LEFT from RIGHT\n"; //PROBLEM IS HERE Level[X][Y] = 1; // block it X = X - 1; moved = 1; } } What I am doing is I am checking if Level[X-1][Y] is 1, indicating a column, so I can not move my player there. However for some reason, despite it being 1 and not 0 (as indicated by the output), the IF statement is still accessed. Any help will be appreciated.

• Does the '#' modifier for cropping images in Paperclip work only for square images?

  - by user3451384

  It is very well documented that you can create square thumbnails with center cropping with Paperclip (4) and Rails (4). I would like to have an image of very specific dimensions (e.g. 200x100) and if input an image of let's say 800x200 it is first resized to 400x100 and then the width (400) is cropped down to 200 pixel from the center (i.e. 100px cut from the right and 100 px cut from the left). I tried with 200x100# and it does not appear to work (i.e. the '#' has no effect). I have found that I could adapt other solutions such as this, but I was wondering if '#' is supposed to work only for cropping to square images, or is a Paperclip bug or I am doing something wrong...

• [jquery] Autogrow Textarea '+' Parent div height

  - by Shishant

  Hello, My Html is like this: <div style="height: 90px;" class="tabtextarea"> <div>Description:</div> <textarea style="height: 85px;">TEXT...</textarea> </div> As you can see textarea is contained within a div with specific height so that it doesnt break layout on some browsers due to float styling and etc I am using. I saw few jquery plugins that resize the textarea but is there any solution with which I can resize parent div too? There is no need for live resizing, resizing just once when page is loaded is preferred as the data is already populated in it. Thank You.

• Need to sync two lists with atrribute time, but times aren't equal

  - by virgula24

  I gonna try to describe my problem the best i can. I have two lists, one with audio frames and other with color frames (not relevant). Both of them have timestamps, they were captured at the same moment but at different instants. So, i have like this: index COLOR AUDIO 0 841 846 1 873 897 2 905 948 3 940 1000 the frames start at high numbers because they were captured and then trimmed to specific parts, but im shot, frame 0 is synced with only 5ms apart(timestamp in ms). On every case i have, the audio frames count is less than the color count. I need to make them have the same count. The stating frames may be coloraudio, color

• How can I get the Forever to write to a different log file every day?

  - by user1438940

  I have a cluster of production servers running a Node.JS app via Forever. As far as I can tell, my options for log files are as follows: Let Forever do it on its own, in which case it will log to ~/.forever/XXXX.log Specify one specific log file for the entire life of the process What I'd like to do, however, is have it log to a different file every day. eg. 20121027.log, 20121028.log, etc. Is this possible?

• What is the right way to modify a wordpress query in a plugin?

  - by starepod

  Basically i am playing with a plugin that allows future-dated posts on archive pages. My question is broader than this specific functionality, but everyone likes some context. I have my head around many of the plugin development concepts, but must be missing something very basic. I can successfully rewrite a query that gives me the results i want like this: function modify_where( $where ) { global $wp_query; // define $year, $cat, etc if( is_archive() ) { $where = " AND YEAR(wp_posts.post_date)='".$year."' AND wp_term_taxonomy.taxonomy = 'category' AND wp_term_taxonomy.term_id IN ('".$cat."') AND wp_posts.post_type = 'post' AND (wp_posts.post_status = 'publish' OR wp_posts.post_status = 'future')"; } return $where; } add_filter('posts_where', 'catCal_where' ); However, if i attempt to create a new WP_Query('different_query_stuff') after the main loop the new query uses the same WHERE statement outlined above. The question is : What am I missing? Thanks.

• Byte manipulation in PHP

  - by Michael Angstadt

  In PHP, if you have a variable with binary data, how do you get specific bytes from the data? For example, if I have some data that is 30 bytes long, how do I get the first 8 bytes? Right now, I'm treating it like a string, using the substr() function: $data = //... $first8Bytes = substr($data, 0, 8); Is it safe to use substr with binary data? Or are there other functions that I should be using? Thanks.

• Cant handle it (jQuery hanlder understanding needed)

  - by chainwork

  I'm embarrassed to even ask BUT could someone help me understand what a "handler" is. I am new to jQuery and the API constantly has references similar to the following: toggle( handler(eventObject), handler(eventObject), [ handler(eventObject) ] ) I scratch my head and say to myself "what the hell is a handler". Then I check my 2 jquery books and don't really see anything specific there. I get what an event handler does, it handles an event. But the word handler in the above context confuses me including "eventObject". I tried to google it but could not really find a really clear definition of what exactly a handler is as it relates to jquery. Thanks for your help =]

• How to turn one server into many servers? (Virtualization/VMWare)

  - by user1229962

  I'm hoping for a high level discussion of this problem I know is quickly approaching my application. I have a server that binds on a specific port and manages TCP Sockets from my clients. I know that it is common practice to use VMWare to virtualize servers and run multiple servers at once. How can a single server design be changed to support multiple servers? Multiple servers can't bind to the same port. If I had to guess I would say a proxy server binds to the port and then sends connections off to the other servers to be handled as if it was still a single server application. I'm wondering what options there are and what are the common practices for solving this problem? Thanks in advance!

• Vim: `cd` to path stored in variable

  - by tsyu80

  I'm pretty new to vim, and I'm having a hard time understanding some subtleties with vim scripting. Specifically, I'm having trouble working with commands that expect an unquoted-string (is there a name for this?). For example cd some/unquoted/string/path The problem is that I'd like to pass a variable, but calling let pathname = 'some/path' cd pathname will try to change the current directory to 'pathname' instead of 'some/path'. One way around this is to use let cmd = 'cd ' . pathname execute cmd but this seems a bit roundabout. This StackOverflow question actually uses cd with a variable, but it doesn't work on my system ("a:path" is treated as the path as described above). I'm using cd as a specific example, but this behavior isn't unique to cd; for example, the edit command also behaves this way. (Is there a name for this type of command?)

• SQLite Queries for dates

  - by user2909616

  I have a SQLite data base which I am pulling data for a specific set of dates (lets say 01-01-2011 to 01-01-2011). What is the best way to implement this query into SQL. Ideally I would like the following line to run: SELECT * FROM database where start_date < date_stamp and end_date date_stamp This obviously does not work when I store the dates as strings. My solution (which I think is messy and I am hoping for another one) is to convert the dates into integers in the following format: YYYYMMDD Which makes the above line able to run (theoretically). IS there a better method? Using python sqlite3 Would the answer be any different if I were using SQL not SQLite

• Looking for another regex explanation

  - by Sam

  In my regex expression, I was trying to match a password between 8 and 16 character, with at least 2 of each of the following: lowercase letters, capital letters, and digits. In my expression I have: ^((?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[a-z])(?=.*[A-Z]).{8,16})$ But I don't understand why it wouldn't work like this: ^((?=\d)(?=[a-z])(?=[A-Z])(?=\d)(?=[a-z])(?=[A-Z]){8,16})$ Doesnt ".*" just meant "zero or more of any character"? So why would I need that if I'm just checking for specific conditions? And why did I need the period before the curly braces defining the limit of the password? And one more thing, I don't understand what it means to "not consume any of the string" in reference to "?=".

• Selecting only the entries that have a distinct combination of values?

  - by Theodore E O'Neal

  I have a table, links1, that has the columns headers CardID and AbilityID, that looks like this: CardID | AbilityID 1001 | 1 1001 | 2 1001 | 3 1002 | 2 1002 | 3 1002 | 4 1003 | 3 1003 | 4 1003 | 5 What I want is to be able to return all the CardID that that have two specific AbilityID. For example: If I choose 1 and 2, it returns 1001. If I choose 3 and 4, it returns 1002 and 1003. Is it possible to do this with only one table, or will I need to create an identical table and do an INNER JOIN on those?
