  • Finding vars from dynamically created namespaces in clojure

    - by Tom Crayford
    The following test fails: (ns clojure_refactoring.rename-fn-test (:use clojure.test)) (deftest test-fn-location (in-ns 'refactoring-test-fn-rename) (clojure.core/refer-clojure) (defn a [b] (inc b)) (in-ns 'clojure_refactoring.rename-fn-test) (is (not= (find-var 'refactoring-test-fn-rename/a) nil)) (remove-ns 'refactoring-test-fn-rename)) That is, find-var (of a var I've just created, in a namespace I've just create) returns nil. This behaviour doesn't happen at the repl, where typing out the steps of the test works just fine. Am I doing something wrong, or is this just something that doesn't work in clojure right now?

  • How to get the parameter names of an object's constructors (reflection)?

    - by Tom
    Say I somehow got an object reference from an other class: Object myObj = anObject; Now I can get the class of this object: Class objClass = myObj.getClass(); Now, I can get all constructors of this class: Constructor[] constructors = objClass.getConstructors(); Now, I can loop every constructor: if (constructors.length > 0) { for (int i = 0; i < constructors.length; i++) { System.out.println(constructors[i]); } } This is already giving me a good summary of the constructor, for example a constructor public Test(String paramName) is shown as public Test(java.lang.String) Instead of giving me the class type however, I want to get the name of the parameter.. in this case "paramName". How would I do that? I tried the following without success: if (constructors.length > 0) { for (int iCon = 0; iCon < constructors.length; iCon++) { Class[] params = constructors[iCon].getParameterTypes(); if (params.length > 0) { for (int iPar = 0; iPar < params.length; iPar++) { Field fields[] = params[iPar].getDeclaredFields(); for (int iFields = 0; iFields < fields.length; iFields++) { String fieldName = fields[i].getName(); System.out.println(fieldName); } } } } } Unfortunately, this is not giving me the expected result. Could anyone tell me how I should do this or what I am doing wrong? Thanks!

    - by Tom
    Hi, Here's what I want: I have an element in my html code, and I want to assign a function to the onClick event, depending on some conditions to be known down the road.

  • C# How to output to GUI when data is coming via an interface via MarshalByRefObject?

    - by Tom
    Hey, can someone please show me how i can write the output of OnCreateFile to a GUI?

  • How do I change the name of an application tab?

    - by Tom Rom
    I'm working on a facebook page for a client and with the new profiles pages starting to roll out I've come across an issue with the name of the app I created. The original profiles which most of you will see here - http://www.facebook.com/DrMartyBecker says "Welcome" as the tab name. On the new profile pages the tab says 'drMARTY', I can't find the place where I can modify the name. So i was wondering if there was a way to change this and where. Thanks for the help!

    - by Tom

I had a project running in VS2008 and when i went back to it, the code from another project had been swapped in the Program.cs class. I havent made any mistakes, im not talking about some code- i mean the whole project had been swapped out. Its as if the .proj files or .soln files had been swapped from their project folders??? EDIT Ive restarted laptop, opened the code again and its still showing the wrong code BUT when i execute it, its the right code?!?!?!

    I'm developping a web application in Eclipse and I'm using maven, spring and tomcat. Now the problem I have is that debug as = debug on server doesn't work. I just get exceptions. (and yes I've created the server) If I use the mvn command to compile it, put the war in my tomcat webapps dir and start my tomcat the application works fine. But for the functionallity I'm now working on debugging would be usefull.

  • Using arrays in Jquery

    - by Tom
    Here is a code: <input type="button" id="array[1]" value="Value1" /> <input type="button" id="array[2]" value="Value2" /> <input type="button" id="array[3]" value="Value3" /> And I want to do something like that: $('#array').click(function() { id = this.id; $.ajax({ here goes type, url, data and else }); }) I want to id add array's number. For example, if I click button where id is array[3] so id gets value of 3 in Jquery's function. Hope you got what I mean.

  • Want to check fields for data fast.

    - by Tom
    We have a database setup that consists of two parts: a static structure, and dynamic additions. For each database, the dynamic can be different, and sometimes we don't have data for all the dynamic fields. Rigt now, we check for empties by looking at the total count of records in the entire table, but we want to move to a more refined method of checking for empties if possible. Is it possible to quickly check through several hundred fields and see which ones are empty and which ones are populated?

  • Reboot windows machines at a certain time of day and automatically login with Python

    - by Tom
    I know how to reboot machines remotely, so that's the easy part. However, the complexity of the issue is trying to setup the following. I'd like to control machines on a network for after-hours use such that when users logoff and go home, or shutdown their computers, whatever, python or some combination of python + windows could restart their machines (for cleanliness) and automatically login, running a process for the night, then in the morning, stop said process and restart the machine so the user could easily login like normal. I've looked around, haven't had too terribly much luck, though it looks like one could do it with a changing of the registry. That sounds like a rough idea though, modifying the registry on a per-day basis. Is there an easier way?

  • Find objects between two dates MongoDB

    - by Tom
    I've been playing around storing tweets inside mongodb, each object looks like this: { "_id" : ObjectId("4c02c58de500fe1be1000005"), "contributors" : null, "text" : "Hello world", "user" : { "following" : null, "followers_count" : 5, "utc_offset" : null, "location" : "", "profile_text_color" : "000000", "friends_count" : 11, "profile_link_color" : "0000ff", "verified" : false, "protected" : false, "url" : null, "contributors_enabled" : false, "created_at" : "Sun May 30 18:47:06 +0000 2010", "geo_enabled" : false, "profile_sidebar_border_color" : "87bc44", "statuses_count" : 13, "favourites_count" : 0, "description" : "", "notifications" : null, "profile_background_tile" : false, "lang" : "en", "id" : 149978111, "time_zone" : null, "profile_sidebar_fill_color" : "e0ff92" }, "geo" : null, "coordinates" : null, "in_reply_to_user_id" : 149183152, "place" : null, "created_at" : "Sun May 30 20:07:35 +0000 2010", "source" : "web", "in_reply_to_status_id" : { "floatApprox" : 15061797850 }, "truncated" : false, "favorited" : false, "id" : { "floatApprox" : 15061838001 } How would I write a query which checks the *created_at* and finds all objects between 18:47 and 19:00? Do I need to update my documents so the dates are stored in a specific format? Thanks

  • Best workflow with Git & Github

    - by Tom Schlick
    Hey guys, im looking for some advice on how to properly structure the workflow for my team with git & github. we are recent svn converts and its kind of confusing on how we should best setup our day-to-day workflow. Here is a little background, im comfortable with command line and my team is pretty new to it but can follow use commands. We all are working on the same project with 3 environments (development, staging, and production). We are a mix of developers & designers so some use the Git GUI and some command line. Our setup in svn went something like this. We had a branch for development, staging and production. When people were confident with code they would commit and then merge it into the staging. The server would update itself and on a release day (weekly) we would do a diff and push the changes to the production server. Now i setup those branches and got the process with the server running but its the actual workflow that is confusing the hell out of me. It seems like overkill that every time someone makes a change on a file they would create a new branch, commit, merge, and delete that branch... from what i have read they would be able to do it on a specific commit (using the hash), do i have that right? is this an acceptable way to go about things with git? any advice would be greatly appreciated.

  • Call a non member funcion on an instance before is constructed.

    - by Tom
    Hi everyone. I'm writing a class, and this doubt came up. Is this undef. behaviour? On the other hand, I'm not sure its recommended, or if its a good practice. Is it one if I ensure no exceptions to be thrown in the init function? //c.h class C{ float vx,vy; friend void init(C& c); public: C(); ~C(); }; //c.cpp C::C() { init(*this); } void init(C& c) //throws() to ensure no exceptions ? { c.vx = 0; c.vy = 0; } Thanks in advance

  • Stackoverflow interesting tags

    - by Tom
    So, that's how works Interesting Tags: I add into them my interested tags like php, mysql, jquery and so on. Then, if any of questions has the same tags as mine it makes background orange. I understand how to use jquery to do that (there were related questions to that), but without mysql it can't be done. Now, here is a question. How is it done? I imagine like that: There is a row in mysql for every member, let's call it "interested_tags". After I write and submit my tag through input, it is being written in a row "interested_tags". Then, the main page has a query which shows all answers and it always checks answer's with mine tags with strpos like this if(strpos($question_tags, $my_tags) === true) {        //and here will be made background orange } Am I thinking right or is there any way to do it?

  • Why Is Java Missing Access Specifiers?

    - by Tom Tresansky
    Does anyone understand why Java is missing: An access specifier which allows access by the class and all subclasses, but NOT by other classes in the same package? (Protected-minus) An access specifier which allows access by the class, all classes in the same package, AND all classes in any sub-package? (Default-plus) An access specifier which adds classes in sub-packages to the entities currently allowed access by protected? (Protected-plus) I wish I had more choices than protected and default. In particular, I'm interested in the Protected-plus option. Say I want to use a Builder/Factory patterned class to produce an object with many links to other objects. The constructors on the objects are all default, because I want to force you to use the factory class to produce instances, in order to make sure the linking is done correctly. I want to group the factories in a sub-package to keep them all together and distinct from the objects they are instantiating---this just seems like a cleaner package structure to me. No can do, currently. I have to put the builders in the same package as the objects they are constructing, in order to gain the access to defaults. But separating project.area.objects from project.area.objects.builders would be so nice. So why is Java lacking these options? And, is there anyway to fake it?

  • Canvas draw calls are rendering out of sequence

    - by Tom Murray
    I have the following code for writing draw calls to a "back buffer" canvas, then placing those in a main canvas using drawImage. This is for optimization purposes and to ensure all images get placed in sequence. Before placing the buffer canvas on top of the main one, I'm using fillRect to create a dark-blue background on the main canvas. However, the blue background is rendering after the sprites. This is unexpected, as I am making its fillRect call first. Here is my code: render: function() { this.buffer.clearRect(0,0,this.w,this.h); this.context.fillStyle = "#000044"; this.context.fillRect(0,0,this.w,this.h); for (var i in this.renderQueue) { for (var ii = 0; ii < this.renderQueue[i].length; ii++) { sprite = this.renderQueue[i][ii]; // Draw it! this.buffer.fillStyle = "green"; this.buffer.fillRect(sprite.x, sprite.y, sprite.w, sprite.h); } } this.context.drawImage(this.bufferCanvas,0,0); } This also happens when I use fillRect on the buffer canvas, instead of the main one. Changing the globalCompositeOperation between 'source-over' and 'destination-over' (for both contexts) does nothing to change this. Paradoxically, if I instead place the blue fillRect inside the nested for loops with the other draw calls, it works as expected... Thanks in advance!

  • How can I use SCM on linked files in VS2008 projects?

    - by Tom Bushell
    Background: I'm using Visual-SVN V. 1.7.5 with VS2008. I'm fairly new to SVN. I have a Solution that uses source files that will be shared with other Solutions. I've put these files in a folder called "Shared", and added them to my Solution using "Add - Existing Item... - Add As Link" which works fine as far as VS2008 is concerned. But when I try to add the linked files to SVN using the "Add to Suversion" menu item on the file's context menu, I get a warning: "...not added to Subversion because it is out of working copy. Please setup working copy root using Visual SVN - Set Working Copy Root menu". I tried this, but this seems to change the root directory of the whole solution - not what I want to do. Googling and searching SO indicates that I may want to set up some SVN Externals. I tried to follow the examples, using the command line for the first time with Visual-SVN. But I just got a bunch of error messages I didn't understand. Questions: Are Externals the way to go here? If so, can someone provide some detailed, step-by-step help on how to do this with Visual-SVN?

  • How to embed a google map with a changeable area?

    - by Tom
    I haven't worded this very well But basically, I'd like to embed a map on my site - but the area it shows will change. I've tried doing this, but it never seems to work as it will focus on the wrong area - the old area, rather than the new area. Basically, I'd like a google map code that uses $place as a location. Thanks.
