• How much RAM used by Python dict or list?

  - by Who8MyLunch

  My problem: I am writing a simple Python tool to help me visualize my data as a function of many parameters. Each change in parameters involves a non-trivial amount of time, so I would like to cache each step's resulting imagery and supporting data in a dictionary. But then I worry that this dictionary could grow too large over time. Most of my data is in the form of Numpy arrays. My question: How would one go about computing the total number of bytes used by a Python dictionary. The dictionary itself may contain lists and other dictionaries, each of which contain data stored in Numpy arrays. Ideas?

• Hudson's FindBugs plugin reports line number "-1" for bugs. Ideas?

  - by John B.

  Greetings, I have a simple test project set up in Hudson and the project's build process (a batch file) generates a findbugs.xml file. This is processed by Hudson's FindBugs plugin but it shows the line number of the bugs as "-1" instead of their actual line number. A coworker suggested I enable debug info for the compiler. I used the -g "Generate all debugging info" option for javac but nothing seemed to change. My build command is: javac -g -classpath C:\testWebApp1\src -d C:\testWebApp1\build C:\testWebApp1\src\*.java The only other thing in the build.bat file is a call to the FindBug tool (text UI). Here is what the FindBugs Plugin says about the first bug: File: GenerateHellos.java, Line: -1, Type: UUF_UNUSED_FIELD, Priority: Normal, Category: PERFORMANCE Any ideas? Thanks a ton!

• How to profile my C++ application on linux

  - by richard

  HI, I would like to profile my c++ application on linux. I would like to find out how much time my application spent on CPU processing vs time spent on block by IO/being idle. I know there is a profile tool call valgrind on linux. But it breaks down time spent on each method, and it does not give me an overall picture of how much time spent on CPU processing vs idle? Or is there a way to do that with valgrind. Thank you.

• postback __EVENTTARGET ID in Page.Request.Form has $ not _ in ASP.NET

  - by Industry86

  I am using the ToolkitScriptManager from the Ajax tool kit and I am having a problem finding my button's ID. My ID's on my controls come back with $ symbols instead of _ symbols, like the following: Grid$ctl06$insertButton This obviously causes problems when attempting to find the control from the Page.Request.Form keys. I cannot seem to find the determining factor that would cause this. Now, I know this is the name and in my source I see that the ID is with the _, so why is the Page.Request.Form showing up with the $ symbol instead? Anybody encounter this before?

• How do I get the icons of TinyMCE to show?

  - by ggfan

  I installed TinyMCE and I have the textbox and the functions work(such as , ) but I don't see the tool box that has displays all the functions. Like in this example. How do I get the images to show? All I have is the textbox. I used the code from the example link and theirs has the images and all I have is the textbox. What part do I edit to be able to see the icons? //my source link <script type="text/javascript" src="/tinymce/jscripts/tiny_mce/tiny_mce.js"> tinyMCE.init({ // Example content CSS (should be your site CSS) content_css : "style12.css", // Drop lists for link/image/media/template dialogs template_external_list_url : "/tinymce/examples/lists/template_list.js", external_link_list_url : "/tinymce/examples/lists/link_list.js", external_image_list_url : "/tinymce/examples/lists/image_list.js", media_external_list_url : "/tinymce/examples/lists/media_list.js",

• replace \n and \r\n with <br /> in java

  - by Bala R

  This has been asked several times for several languages but I can't get it to work. I have a string like this String str = "This is a string.\nThis is a long string."; And I'm trying to replace the \n with <br /> using str = str.replaceAll("(\r\n|\n)", "<br />"); but the \n is not getting replaced. I tried to use this RegEx Tool to verify and I see the same result. The input string does not have a match for "(\r\n|\n)". What am i doing wrong ?

• Will an IO blocked process show 100% CPU utilization in 'top' output?

  - by Alex Stoddard

  I have an analysis that can be parallelized over a different number of processes. It is expected that things will be both IO and CPU intensive (very high throughput short-read DNA alignment if anyone is curious.) The system running this is a 48 core linux server. The question is how to determine the optimum number of processes such that total throughput is maximized. At some point the processes will presumably become IO bound such that adding more processes will be of no benefit and possibly detrimental. Can I tell from standard system monitoring tools when that point has been reached? Would the output of top (or maybe a different tool) enable me to distinguish between a IO bound and CPU bound process? I am suspicious that a process blocked on IO might still show 100% CPU utilization.

• What to do with someone who can only use "the one true language"?

  - by Rob Wells

  G'day, How do you work with someone when they haven't been able to see that there is a range of other languages out there beyond "The One True Path"? I mean someone who hasn't grown up to realise that the modern software professional has a range of tools in his toolbox. Someone who has a well-equipped toolbox and then selects the best tool for the job at hand. The person who's knee jerk reaction is, for example, "We must do this is C++!" "Everything must be done in C++!" What's the best approach for these people? How do you open them up to the fact that "not everything is a nail." cheers,

• How to use AOP to intercept a method call in super on an argument?

  - by hleinone

  I'm extending a class and overriding a method. All I want to do is to call super, but with a modified argument that gets intercepted upon one of its methods is called. An example makes it more clear: // Foo is an interface and also this method is part of an interface @Override public void foo(Foo foo) { // I want to intercept the call to foo.bar() in super super.foo(foo); } I'd rather use a tool that doesn't require a compiler of its own. What would be the optimal one?

• using different string files in android

  - by boreas

  I'm porting my iPhone app to android and I'm having a problem with the string files now. The app is a translation tool and users can switch the languages, so all the localized strings are in both languages and they are independent from what locale the OS is running. For iOS version I have different files like de.strings, en.strings and fr.strings and so on. For every target with specified language pair I read the strings from the string tables, e.g. for de-fr I will include de.strings and fr.strings in project and set the name of the string tables in the info-list file and read strings from them. In the end I have one project containing different targets (with different info-list files) and all are well configured. I'm intending to do the same on android platform, but Is only one strings.xml allowed per project? How do I set different build target? How do I specify per target which strings.xml it should read?

• How do I learn Scheme?

  - by Gautam

  Hey, I'm a relative newbie to programming. I've picked up some very basic Java (File I/O, GUIs, inheritance) and would like to take a look at functional programming - in particular, I would like to learn Scheme. I'm having some trouble finding a Scheme implementation I can understand. Interpreters are weird; I'm not sure how to save my programs and create executables. I've downloaded PLT Scheme, but I would prefer using something less condescending, something similar to NetBeans. Is there a plugin or tool that will allow me to quickly and easily create and manage Scheme programs? All help is appreciated!

• Change Message on Sony Reader to “Do not disconnect”

  - by Martin Broerse

  When I connect a Sony Reader to an USB port “USB connected” is shown on the Reader. When the Sony “Reader Library” software is started this message changes to “Do not disconnect”. I want to implement this in a software tool to. There seems to be no file locked. Perhaps it is done via ebookUsb.dll. Does anybody know how this is done from any programming language? I like to see an example.

• Stylesheets loading but styles not showing...

  - by echobase

  Hi- I have a website I created in VS2010 and am trying to run with IIS7. My website starts in all major browsers but for some reason the styles are not applied even though I've confirmed using Firebug that the stylesheets have indeed loaded. Also, when I use the inspect tool to click on an element, I can see in the right-side box the specific styles that are supposed to be applied. I thought this might be a permissions issue but I think I've got those set properly. Any help would be appreciated. Thanks.

• Which language shouöd I take?

  - by Kovu

  Hi. I will build an application, that will be like a mix from a trojaner and a remote tool. It will be a spy programm for our company, so the IT Admin and Managment can see what the people are doing or not. (Only for explayning, please don't discuss about "uhhh tahts not ok"). I must choose a language for that. My best knowlegde is in C#.Net and VB.Net, but one main feature should be: No framework must be installed - so DotNet is out of the run. I decided to VB6 and a few minutes ago I ask for a IDE and some people say: Don't use it, it's too old. So, I must ask: What language do you prefer for such an project?

• How can I edit a js file sent by the server before it gets to my browser?

  - by pstone

  During a normal browsing session I want to edit a specific javascript file before the browser receives since once it gets there it's impossible to edit. Is there are any tool for this? For what I need it I can't just save it and edit it on my disk. I'm ready to learn how to program it myself but if anyone can point out more or less what I have to do I'd be very grateful. I'd have to intercept the packets until I have the whole file while blocking the browser from receiving it any part of it, then edit it manually and forward it to the same port. I don't think I can do this by just using pcap, I've read a bit about scapy but I'm not sure if it can help me either. Thanks in advance.

I have added *.cl under Tool/Text editor/File extensions and copied usertype.dat into the common7/ide folder, but VS underlines keywords like float4 or cross. Is it necessary to add some key in registry or can somebody propose a tutorial? Thanks in advance. PS i have already asked similar question old one question, but now i am looking explicit for a solution with vs2010. It is not bad, but really nerves and deflects me from programming tasks.

• database encryption questions

  - by 5YrsLaterDBA

  We are using Sybase SQL Anywhere 11. We need to encrypt some of our tables in our database. I followed the instruction and did it. We selected the "strong" option with encryptionKey and AES256_FIPS algorithm. But there are something I am not clear about them. It will require encryptonKey when we create the database, remove the database and start the database server but it will NOT require encryptionKey when we stop the database server and connect to the server to create tables and add data. Why there is NO encryptionKey asked when we connect to it or try to stop the server? I am doing something wrong? don't know how to test the encryption? I still can see all plain text in the encrypted tables when I use Sybase Central tool. If somebody knows the database user name and password, he/she can connect to the database and read the content without the encryptionKey. is this right?

• Catching uncaught exceptions

  - by kajyr

  Hi everybody. In my workplace we are mantaining a lot of ecommerce websites, some coded better than others. On some of those, sometimes uncaught exceptions are thrown, and showed by the alertbox from the flash player debug (If you have it installed). To rise the average user experience I'd like to report all those exceptions throught a in house tool we already have. Is there a way to catch those exceptions? Maybe the flash player debug exposes them to javascript, or in some other way.

• Find and list all functions/methods in a set of JavaScript files

  - by Dan Milstein

  Is there a way to read a set of JavaScript files, and output a description of where every function/method is defined? I realize that this is likely impossible in full generality, due to the extreme dynamic nature of the language. What I'm imagining is something which gets the (relatively) straightforward cases. Ideally, I'd want it figure out where, e.g. some method got attached to string or hash or some other fundamental class (and also just let you find all the classes/functions that get defined once in one place). Does such a tool exist?

• Rendering sub tools on vertical toolbar

  - by user146780

  I was wondering how ex Photoshop and Expression Design render sub tools. These show up when for example you hold your mouse down on the fill tool, a sub menu comes up to your right with the fill and gradient tools. I'm just not sure how to go about this because this sub menu would essentially have to be an extension of my toolbar, but then it would find itself on my Frame control. How is this handled? Would it be a good idea to just paint on my frame?

• Outlook 2007 plugin

  - by JL

  I am about to embark on my first outlook 2007 plugin. I would like to create a new tool bar that will have a button that will initially be disabled. When the user selects a message the button should be enabled... but only if the email is of a certain type of email... This is where I need your expert advice, is there a way to quickly flag an email in outlook, so that in the email select event you can look for a property of that email... for example... on_select if mail.type = "FromISP" then I would prefer not to use the from field.... the other thing is during the send process I need to set the flag, I am doing this again using .net so I have full control over how the mail is created. Any ideas would help... Thanks

• How to extract data from Google Analytics and build a data warehouse (webhouse) from it?

  - by nkaur301

  I have click stream data such as referring URL, top landing pages, top exit pages and metrics such as page views, number of visits, bounces all in Google Analytics. I am required to build a data warehouse from scratch(which I believe is known as web-house) from this data. My questions are:- 1)Is it possible? Every day data increases (some in terms of metrics or measures such as visits and some in terms of new referring sites), how would the process of loading the warehouse go about? 2)What ETL tool would help me to achieve this? Pentaho I believe has a way to pull out data from Google Analytics, has anyone used it? How does that process go? Any references, links would be appreciated besides answers.
