  • Want to improve my simple site/db backup script with auto removal of old backups.

    - by Robert Robb
    I have the following simple script for backing up my website files and db. The script is run each day via a cron job. #!/bin/sh NOW=$(date +"%Y-%m-%d") mysqldump --opt -h localhost -u username -p'password' dbname > /path/to/folder/backup/db-backup-$NOW.sql gzip -f /path/to/folder/backup/db-backup-$NOW.sql tar czf /path/to/folder/backup/web-backup-$NOW.tgz /path/to/folder/web/content/ It works great, but I don't want loads of old backups clogging my system. How can I modify the script to remove any backups older than a week when the script is run?

  • Has anyone got a simple step by step Mozilla plugin tutorial.

    - by s1mm0t
    I'm trying to create a Mozilla browser plugin for the sole purpose of detecting with javascript whether or not an application that I have written is installed. This was inspired by another stackoverflow question and answer on a similar subject. All I want really is a HelloWorld type example as what I need to write will be even simpler than that. There is a lot of information on the Mozilla website, but as a plugin noob and a C++ novice I'm experiencing information overload. I just need a step by step "this is how to create your first simple plugin". I have already written the IE equivalent by following this ATL tutorial. This is the kind of level of guide that I would ideally like to find. Please note, this is specifically about Mozilla plugins and not extensions - Googling this subject brings up a lot of information about extensions in addition to plugins.

  • Junit (3.8.1) testing that an exception is thrown (works in unit test, fails when added to a testSui

    - by Mike Cargal
    I'm trying to test that I'm throwing an exception when appropriate. In my test class I have a method similar to the following: public void testParseException() { try { ClientEntitySingleton.getInstance(); fail("should have thrown exception."); } catch (RuntimeException re) { assertEquals( "<exception message>", re.getMessage()); } } This works fine (green bar) whenever I run that single unitTest class. However, when I add that test to a testSuite, I get a red bar Unit test failure reported on the exception. One more thing... it works in the testSuite, if it's the first test in the suite. Actually, I'm doing two of these tests and just figured out that if I make them the first two tests in the suite, all is good, but I get this failure if a "regular" test precedes it. So I have a work-around, but no real answer. Any ideas? Heres'a stack trace of the "failure" java.lang.RuntimeException: ProcEntity client dn="Xxxxxx/Xxxx/XXX" is defined multiple times. at com.someco.someprod.clientEntityManagement.ClientEntitySingleton.addClientEntity(ClientEntitySingleton.java:247) at com.someco.someprod.clientEntityManagement.ClientEntitySingleton.startElement(ClientEntitySingleton.java:264) at org.apache.xerces.parsers.AbstractSAXParser.startElement(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanStartElement(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl$FragmentContentDispatcher.dispatch(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanDocument(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XMLParser.parse(Unknown Source) at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source) at com.someco.someprod.clientEntityManagement.ClientEntitySingleton.parse(ClientEntitySingleton.java:216) at com.someco.someprod.clientEntityManagement.ClientEntitySingleton.reload(ClientEntitySingleton.java:303) at com.someco.someprod.clientEntityManagement.ClientEntitySingleton.setInputSourceProvider(ClientEntitySingleton.java:88) at com.someco.someprod.clientEntityManagement.test.TestClientBase.setUp(TestClientBase.java:17) at com.someco.someprod.clientEntityManagement.test.TestClientEntityDup.setUp(TestClientEntityDup.java:8) at junit.framework.TestCase.runBare(TestCase.java:125) at junit.framework.TestResult$1.protect(TestResult.java:106) at junit.framework.TestResult.runProtected(TestResult.java:124) at junit.framework.TestResult.run(TestResult.java:109) at junit.framework.TestCase.run(TestCase.java:118) at junit.framework.TestSuite.runTest(TestSuite.java:208) at junit.framework.TestSuite.run(TestSuite.java:203) at junit.framework.TestSuite.runTest(TestSuite.java:208) at junit.framework.TestSuite.run(TestSuite.java:203) at org.eclipse.jdt.internal.junit.runner.junit3.JUnit3TestReference.run(JUnit3TestReference.java:128) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:460) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:673) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:386) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:196)

  • Python noob question - why is my simple regex not working?

  • What would you recommend to do simple 2D Graphics?

    - by Tom Ritter
    I want to build a program that will (as part of what it's doing) display lines organically growing and interacting horizontally across the screen. Here's a sample image, just imagine the lines sprouting from the left and growing to the right: The lines would look like the lines used on Google Maps Transit Overlay or OnNYTurf's transit pages. It's a personal project, so I'm open to just about any language and library combination. But I don't know where to start. What have you used in the past to create graphics that are similar to this? What would you recommend? I want it to run on Windows without any extras needed (.Net is fine), and it doesn't have to run elsewhere. I needs to run as an actual program, not javascript in the browser. There's obviously no 'right' answer to this, but the purpose isn't to start an argument about X better than Y but rather just find a list of graphics toolkits that do simple 2D graphics that people recommend because of their ease of use or community or whatever.

  • How to reduce simple cpp application size? (compiled with RAD Studio 2010 cpp builder)

    - by peterg
    I am using rad studio 2010 cpp builder. I've created a new SDI application, added a TCppWebBrowser control and a simple button that onclick trigger the .navigate for the TCppWebBrowser, I compiled it and I got a 1.20mb file, I was expecting less than 700kb at least. How can I reduce the size of the compiled exe? I don't want to use "build with runtime packages", I know that will make it very small but I want to get all the necessary packages and dependencies inside the exe but maybe I am getting more than I use, I tried unchecking/removing a lot of design packages (in project/options/packages) I don't use but the file size didn't decreased. Also I was thinking maybe the TForm component that comes with RAD Studio is giving me more stuff than I need and that could make the file bigger, I mean I only need to drop a webbrowser control and a few buttons in the form, maybe there's a minimal form component I could use to replace TForm. Any suggestions will be appreciated.

  • Glassfish V3 won't start

    Hi everybody, I installed NetBeans 6.8 and tried to run the GlasshFish V3 server. I'm working under Windows Vista 32 Bits. First, it won't run.

  • How to add event listners / signals to a simple superman class?

How to add such event listner and event function to my class?

  • What task can I automate in Python that's fun, simple, and useful?

    - by froadie
    I'm trying to learn Python. I'm going to eventually be using it at work, but I don't have an active project in it as of now. I've been reading through some documentation and would like to learn some basics, but I learn best when actually coding. So I'm thinking of attempting a small Python project just to sort of "get my feet wet" in Python. While reading/asking around, I've often heard people say that if you need a Python project you should automate some task you do on your computer on a day-to-day basis. Maybe I'm not so imaginative, but I can't think of anything I'd like to automate... Does anyone have any ideas of something simple, fun, and not too time-consuming that someone can automate to get some basic experience in Python? Something that they would come out of feeling like they accomplished something fun and useful?

  • Is there any simple way to test two PNGs for equality?

    - by Mason Wheeler
    I've got a bunch of PNG images, and I'm looking for a way to identify duplicates. By duplicates I mean, specifically, two PNG files whose uncompressed image data are identical, not necessarily whose files are identical. This means I can't do something simple like compare CRC hash values. I figure this can actually be done reliably since PNGs use lossless compression, but I'm worried about speed. I know I can winnow things down a little by testing for equal dimensions first, but when it comes time to actually compare the images against each other, is there any way to do it reasonably efficiently? (ie. faster than the "double-for-loop checking pixel values against each other" brute-force method?)

  • How to create a simple server/client application using boost.asio?

    - by the_drow
    I was going over the examples of boost.asio and I am wondering why there isn't an example of a simple server/client example that prints a string on the server and then returns a response to the client. I tried to modify the echo server but I can't really figure out what I'm doing at all. Can anyone find me a template of a client and a template of a server? I would like to eventually create a server/client application that receives binary data and just returns an acknowledgment back to the client that the data is received.

  • JavaScript and PHP filename coding conventions

    - by Tower
    Hi, I would like to know the popular ways of naming files in JavaScript and PHP development. I am working on a JS+PHP system, and I do not know how to name my files. Currently I do for JS: framework/ framework/widget/ framework/widget/TextField.js (Framework.widget.TextField()) Framework.js (Framework()) So, my folders are lowercase and objects CamelCase, but what should I do when the folder/namespace requires more than one word? And what about PHP? jQuery seems to follow: jquery.js jquery.ui.js jquery.plugin-name.js so that it is jquery(\.[a-z0-9-])*\.js but ExtJS follows completely different approach. Douglas Crockford only gives us details about his preference for syntax conventions.

  • How can Perl's XML::Simple ignore HTML embedded in XML?

    - by Miriam Raphael Roberts
    I have an XML file that I am pulling from the web and parsing. One of the items in the XML is a 'content' value that has HTML. I am using XML::Simple::XMLin to parse the file like so: $xml= eval { $data->XMLin($xmldata, forcearray => 1, suppressempty=> +'') }; When I use Data::Dumper to dump the hash, I discovered that SimpleXML is parsing the HTML into the hash tree: 'content' = { 'div' = [ { 'xmlns' = 'http://www.w3.org/1999/xhtml', 'p' = [ { 'a' = [ { 'href' = 'http://miamiherald.typepad.com/.a/6a00d83451b26169e20133ec6f4491970b-pi', 'style' = 'FLOAT: left', 'img' = [ etc..... This is not what I want. I want to just grab content inside of this entry. How do I do this?

Here's the incredibly simple class I am attempting to declare: Class abc { $a = “Hello!”; } Is there some setting on PHP that i need to turn on? I feel like this is one of those 'did you check if the TV is plugged in' type of issues....

  • Which containers / graphics components to use in a simple Java Swing game?

    - by rize
    I'm creating a simple labyrinth game with Java + Swing. The game draws a randomized labyrinth on the screen, places a figure in the middle, and the player is then supposed to find the way out by moving the figure with arrow-keys. As for now, I'm using a plain background and drawing the walls of the labyrinth with Graphics.drawLine(). I have a custom picture of the figure in a .gif file, which I load as a BufferedImage object. However, I want the player to see only part of the labyrinth at a time, and the screen should follow the figure in the game, as the player moves around. I'm planning to do this by creating an Image object of the whole labyrinth when it is created, and then "cutting" a square around the current position of the figure and displaying this with Graphics.drawImage(). I'm new with Swing though, and I can't figure out how to draw the figure at different positions "above" the labyrinth without redrawing the whole thing. Which container/component should I use for the labyrinth and then for the figure to achieve this?

  • What is a simple way to combine two Emacs major modes, or to change an existing mode?

    - by Winston C. Yang
    In Emacs, I'm working with a file that is a hybrid of two languages. Question 1: Is there a simple way to write a major mode file that combines two major modes? Details: The language is called "brew" (not the "BREW" of "Binary Runtime Environment for Wireless"). brew is made up of the languages R and Latex, whose modes are R-mode and latex-mode. The R code appears between the tags <% and %. Everything else is Latex. How can I write a brew-mode.el file? (Or is one already available?) One idea, which I got from this posting, is to use Latex mode, and treat the code of the form <% ... % as a comment. Question 2: How do you change the .emacs file or the latex.el file to have Latex mode treat code of the form <% ... % as a comment?

  • What's a simple way to web-ify my command-line daemon?

    - by dreeves
    Suppose I have a simple daemon type script that I run on my webserver. I run it in a terminal, with gnu screen, so I can keep an eye on it. That works fine (incidentally, I use this trick). But now suppose I'd like to make a web page where I can keep an eye on my script's output. What's the easiest way to do that? Notes: This is mainly for myself and a couple co-hackers so if websockets is the answer and it only works on Chrome or something, that's acceptable. This question is asking something similar: http://stackoverflow.com/questions/1964494/how-to-make-all-connected-browsers. But I'm hoping for a simpler, quick-and-dirty solution, and especially a general way to quickly do this for any script I might want to keep an eye on from a browswer.

  • How to use List<T>.Find() on a simple collection that does not implement Find()?

    - by Bilal
    Hi, I want to use List.Find() on a simple collection that does not implement Find(). The naive way I thought of, is to just wrap it with a list and execute .Find(), like this: ICollection myCows = GetAllCowsFromFarm(); // whatever the collection impl. is... var steak = new List<Cow>(myCows).Find(moo => moo.Name == "La Vache qui Rit"); Now, 1st of all I'd like to know, C#-wise, what is the cost of this wrapping? Is it still faster to 'for' this collection the traditional way? Second, is there a better straightforward way elegantly use that .Find()? Cheers!

  • Want to build simple SQL admin interface to change a few values in a table.

    - by Adam McC
    i am currently building a system in MSSQL 2K5. i have a table that holds information about certain insurance schemes such as overheads and other things. these values will change occasionally and currently i administer the database straight through the management Studio. i would like to build a simple interface that will allow my colleagues to change these values by selecting the company in a dropdown and the current values will populate. they can then edit these values and submit them to the database. is this possible in the current Visual Studio supplied with MSSQL server 2K5 or do i need to get another product. i am confident that with the help of stack overflow and google i can build this myself, but i need pointed in the right direction as to which environment would be easiest and best to start building it.

  • MVC (model-view-controller) - can it be explained in simple terms?

    - by DVK
    I need to explain to a not-very-technical manager the MVC (model-view-controller) concept and ran into trouble. The problem is that the explanation needs to be on a "your grandma will get it" level - e.g. even the fairly straightforward explanation offered on MVC Wiki page didn't work, at least with my commentary. Does anyone have a reference to a good MVC explanation in simple terms? It would ideally be done with non-techie metaphor examples (e.g. similar to "Decorator pattern is like glasses") - one reason I failed was that all MVC examples I could come up with were development related. I once saw a list of pattern explanations but to the best of my memory MVC was not on it. Thanks!

    Hi, So using the regular MongoDB library in Ruby I have the following query to find average filesize across a set of 5001 documents: avg = 0 total = collection.count() Rails.logger.info "#{total} asset creation stats in the system" collection.find().each {|row| avg += (row["filesize"] * (1/total.to_f)) if row["filesize"]} Its pretty simple, so I'm trying to do the same using map/reduce as a learning exercise. This is what I came up with: map = 'function(){emit("filesizes", {size: this.filesize, num: 1});}' reduce = 'function(k, vals){ var result = {size: 0, num: 0}; for(var x in vals) { var new_total = result.num + vals[x].num; result.num = new_total result.size = result.size + (vals[x].size * (vals[x].num / new_total)); } return result; }' @results = collection.map_reduce(map, reduce) However the two queries come back with two different results! What am I doing wrong?
