• Git in terminal

  - by goodcow

  I tried making my first repo on github. I copy pasted their code while on the directory of my entire system (I think that was a mistake). As a result, the terminal line always says ~ git:(master) ? before every command. It does not go away even when I quit terminal. I am using zsh. The code I pasted was: touch README.md git init git add README.md git commit -m "first commit" git remote add origin https://github.com/***/***.git git push -u origin master On top of that, I can't even seem to figure out how to add my files to the repo. Help on how to not always have git:(master) before every bash command and how to make a repo? Thanks!

• How/When/Where to Extend Gem Classes (via class_eval and Modules) in Rails 3?

  - by viatropos

  What is the recommended way to extend class behavior, via class_eval and modules (not by inheritance) if I want to extend a class buried in a Gem from a Rails 3 app? An example is this: I want to add the ability to create permalinks for tags and categories (through the ActsAsTaggableOn and ActsAsCategory gems). They have defined Tag and Category models. I want to basically do this: Category.class_eval do has_friendly_id :title end Tag.class_eval do has_friendly_id :title end Even if there are other ways of adding this functionality that might be specific to the gem, what is the recommended way to add behavior to classes in a Rails 3 application like this? I have a few other gems I've created that I want to do this to, such as a Configuration model and an Asset model. I would like to be able to add create an app/models/configuration.rb model class to my app, and it would act as if I just did class_eval. Anyways, how is this supposed to work? I can't find anything that covers this from any of the current Rails 3 blogs/docs/gists.

• Can't move li elements from one unorderted list to another

  - by Roland

  I have two un-ordered list <ul id="#list1"> <li>one</li> <li>two</li> </ul> <ul id="#list2"></ul> and two buttons <input id="add" name="yt1" type="button" value="<<" /><br /> <input id="remove" name="yt2" type="button" value=">>" /> If the button with the id add is pressed all elements from #list1 should be move to #list2. How do I move elements from one list to another using JQuery I though of something like the below, but not sure how to do the actual moving $("#add").click(function(){ $("#list1 li").each(function(){ //Do not know what to put in here } })

• Control iTunes from Spotlight (or similar)

  - by joshhunt

  Is there some sort add on or program that lets me easily change (and choose) songs using keyboard shortcuts (or perhaps Spotlight)? The ideal program would add iTunes indexing to Spotlight and allow me to change songs by searching for them in Spotlight (but then not switch the focus to iTunes). I do believe that there was a plugin for Launchy on Windows to do a similar thing. Is such a program available?

• how to save state of dynamically created editTexts

  - by user922531

  I'm stuck at how to save the state of my EditTexts on screen orientation. Currently if text is inputted into the EditTexts and the screen is orientated, the fields are wiped (as expected). I am already calling onSaveInstanceState and saving a String, but I have no clue on how to save the EditTexts which are created in code and then retrieve them and add them to the EditTexts when redrawing the activity. Snippet of my code: My main activity is as follows: public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // get the multidim array b = getIntent().getBundleExtra("obj"); m = (Methods) b.getSerializable("Methods"); // method to draw the layout InitialiseUI(); // Restore UI state from the savedInstanceState. if (savedInstanceState != null) { String strValue = savedInstanceState.getString("light"); if (strValue != null) { FLight = strValue; } } try { mCamera = Camera.open(); if (FLight.equals("true")) { flashLight(); } } catch (Exception e) { Log.d(TAG, "Thrown exception onCreate() camera: " + e); } } // end onCreate /** Called when the back button is pressed. */ @Override public void onResume() { super.onResume(); try { mCamera = Camera.open(); if (FLight.equals("true")) { flashLight(); } } catch (Exception e) { Log.d(TAG, "Thrown exception onCreate() camera: " + e); } } // end onCreate /** saves data before leaving the screen */ @Override protected void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); outState.putString("light", FLight); } /** called when exiting / leaving the screen */ @Override protected void onPause() { super.onPause(); Log.d(TAG, "onPause()"); if (mCamera != null) { mCamera.stopPreview(); mCamera.release(); mCamera = null; } } /* * set up the UI elements - add click listeners to buttons used in * onCreate() and onConfigurationChanged() * * Set the editTexts fields to show the previous readings as Hints */ public void InitialiseUI() { Log.d(TAG, "Start of InitialiseUI, Main activity"); // get a reference to the TableLayout final TableLayout myTLreads = (TableLayout) findViewById(R.id.myTLreads); // Create arrays to hold the TVs and ETs final TextView[] myTextViews = new TextView[m.getNoRows()]; // create an empty array; final EditText[] myEditTexts = new EditText[m.getNoRows()]; // create an empty array; for(int i =0; i<=m.getNoRows()-1;i++ ){ TableRow tr=new TableRow(this); tr.setLayoutParams(new LayoutParams( LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT)); // create a new textview / editText final TextView rowTextView = new TextView(this); final EditText rowEditText = new EditText(this); // setWidth is needed otherwise my landscape layout is OFF rowEditText.setWidth(400); // this stops the keyboard taking up the whole screen in landscape layout rowEditText.setImeOptions(EditorInfo.IME_FLAG_NO_EXTRACT_UI); // add some padding to the right of the TV rowTextView.setPadding(0,0,10,0); // set colors to white rowTextView.setTextColor(Color.parseColor("#FFFFFF")); rowEditText.setTextColor(Color.parseColor("#FFFFFF")); // if readings already sent today set color to yellow if(m.getTransmit(i+1)==false){ rowEditText.setEnabled(false); rowEditText.setHintTextColor(Color.parseColor("#FFFF00")); } // set the text of the TV to the meter name rowTextView.setText(m.getMeterName(i+1)); // set the hint of the ET to the last submitted reading rowEditText.setHint(m.getLastReadString(i+1)); // add the textview to the linearlayout rowEditText.setInputType(InputType.TYPE_CLASS_PHONE);//InputType.TYPE_NUMBER_FLAG_DECIMAL); tr.addView(rowTextView); tr.addView(rowEditText); myTLreads.addView(tr); // add a reference to the textView myTextViews[i] = rowTextView; myEditTexts[i] = rowEditText; } final Button submit = (Button) findViewById(R.id.submitReadings); // add a click listener to the button try { submit.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { Log.d(TAG, "Submit button clicked, Main activity"); preSubmitCheck(m.getAccNo(), m.getPostCode(), myEditTexts); // method to do HTML getting and sending } }); } catch (Exception e) { Log.d(TAG, "Exceptions (submit button)" + e.toString()); } }// end of InitialiseUI I don't need to do anything with these values until a button is clicked. Would it be easier if they were a ListView, i'm guessing I would still have the problem of saving them and retrieving them on rotation. If it helps I have an object m which is a string[][] I could temporarily somehow store them in

• Make Codeigniter ignore directory

  - by Noah Goodrich

  I have Codeigniter installed and working for my main site. But I am now trying to add an add-on domain to the same hosting account, so I can have two sites running on the same hosting. Add-on domains make a new folder in the main public_html folder to store the web files. How can I get Codeigniter to ignore this directory? The site doesn't load properly when I try and view it. I have an SSL on the main site too and redirection for www URLS. Here's my .htaccess file: RewriteEngine on Options +FollowSymLinks RewriteBase / RewriteCond %{HTTP_HOST} ^www\.mysite\.co.uk$ [NC] RewriteRule ^(.*)$ http://mysite.co.uk/$1 [L,R=301] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ /index.php/$1 RewriteCond %{HTTPS} off RewriteCond %{REQUEST_URI} (site|sections|here) RewriteRule ^(.*)$ https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L] RewriteCond %{HTTPS} onsite|sections|here) RewriteRule ^(.*)$ http://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]

• Url Rewriting with Querystrings

  - by Alon

  In IIS 7.5, I'm trying to rewrite a Url such as /about to /content.asp?p=about, with support for QueryString-s, so if the orginal Url was /about?x=y, it should rewrite to /content.asp?p=about&x=y. The basic rewriting is now working, but when I'm trying to add a QueryString it doesn't work. Tried both /about?x=y and /about&x=y. My current rule: <rule name="RewriteUserFriendlyURL1" stopProcessing="false"> <match url="^([^/]+)/?$" /> <conditions> <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" /> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" /> </conditions> <action type="Rewrite" url="content.asp?p={R:1}" /> </rule> How can I fix this? Thank you.

• Problem with increment in inline ARM assembly

  - by tech74

  Hi , i have the following bit of inline ARM assembly, it works in a debug build but crashes in a release build of iphone sdk 3.1. The problem is the add instructions where i am incrementing the address of the C variables output and x by 4 bytes, this is supposed to increment by the size of a float. I think when i increment at some such stage i am overwriting something, can anyone say which is the best way to handle this Thanks C code that the asm is replacing, sum,output and x are all floats for(int i = 0; i< count; i++) sum+= output[i]* (*x++) asm volatile( ".align 4 \n\t" "mov r4,%3 \n\t" "flds s0,[%0] \n\t" "0: \n\t" "flds s1,[%2] \n\t" //"add %3,%3,#4 \n\t" "flds s2,[%1] \n\t" //"add %2,%2,#4 \n\t" "subs r4,r4, #1 \n\t" "fmacs s0, s1, s2 \n\t" "bne 0b \n\t" "fsts s0,[%0] \n\t" : : "r" (&sum), "r" (output), "r" (x),"r" (count) : "r0","r4","cc", "memory", "s0","s1","s2" );

• Design guidelines for cache mechanism

  - by Delashmate

  Hi All, I got assignment to write design for cache mechanism (this is work assignment, not homework), This is my first time writing a design document, Our program display images for doctors, and we want to reduce the parsing time of the images So we want to save the parsed data in advance (in files or inside database) Currently I have several design key ideas: Handle locks - each shared data structure should be handled, also files Test - add test to verify the data from the cache is equal to the data from the files To decouple the connection to the database- not to call directly to the database Cleanup mechanisem- to delete old files if the cahce directory exceed configurable threshold Support config file Support performance tool in the feature I will also add class diagram, data flow charts, and workflow What do you think I should add to the key ideas? Do you know good link to atricales about design? Thanks in advance, Dan

• Adding code to the beginning / end of methods in runtime dynamically

  - by Irchi

  I know instrumentation is a technique to add trace code dynamically into the methods to enable tracing and debugging. I was wondering if this is only a "Trace" option, hard coded into the CLR to add only trace code, or is there the ability to add any code to the methods? For example, I want to check for a condition in the beginning of every single method call in a certain class (say for permissions). Can I do this via adding dynamic code to the beginning of the methods in execution time? I'm not sure how this trace "instrumentation" thing works, but I'm wondering if this can be used for other goals too, or not.

• filter functions problem

  - by Adam

  I'm working on a search component for an app I'm working on and I needed to add some filters to it. I've found an example and got the first filter working fine. Now I'm trying to add a second filter I'm running into problems... In the example I found they use filterFunctions, but I only get an option for filterFunction, why is that? Here's the example code productsCollection.filterFunctions = [ filterByPrice, filterByType, filterByCondition, filterByVendor ] And this is what I'm trying acData.filterFunction = [filterByStatus, filterByDate] but with this code I get the following error message - 1067: Implicit coercion of a value of type Array to an unrelated type Function. Why am I getting this error and how would I go about add multiple filters to my Array Collection? Thanks!

• How to inflate a view in a determined position?

  - by Tivie

  I have an activity with an "Add" and a "Delete" button. The "Add Button" inflates a view, the "Delete Button" removes a selected View. When I inflate a view with the "Add Button", it is automatically drawn below any previously infalted view. I would like to give the user the possibility to move each inflated view up and down, so he could change the order they are show in screen (in a drag'n'drop kind of effect) +---------------------+ +---------------------+ | +-----------------+ | | +-----------------+ | | | View 1 | | | | View 2 | | | +-----------------+ | | +-----------------+ | | | --> | | | +-----------------+ | | +-----------------+ | | | View 2 | | | | View 1 | | | +-----------------+ | | +-----------------+ | +---------------------+ +---------------------+ Is it possible to specify the "position" in which each view is inflated? (for instance, below or above the currently selected view?) If not, what is the best way to accomplish the desired effect? (feel free to ask for any piece of code, if you think it might help)

• lwjgl isKeyDown canceling out other keys

  - by AKrush95

  While trying to create a simple game where a square is manipulated via the keyboard keys, I have come across a small, rather irritating problem. I would like it to work so that when the opposite directional key is pressed, the character will stop; the character may move the other two directions while stopped in this situation. This works perfectly with LEFT and RIGHT held down; the player may move UP or DOWN. If UP and DOWN are held down, however, the player will not move, nor will Java recognize that the LEFT or RIGHT keys were pressed. import java.util.ArrayList; import java.util.Random; import org.lwjgl.*; import org.lwjgl.input.Keyboard; import org.lwjgl.opengl.*; import static org.lwjgl.opengl.GL11.*; public class Main { private Man p; private ArrayList<Integer> keysDown, keysUp; public Main() { try { Display.setDisplayMode(new DisplayMode(640, 480)); Display.setTitle("LWJGLHelloWorld"); Display.create(); } catch (LWJGLException e) { e.printStackTrace(); } p = new Man(0, 0); keysDown = new ArrayList<>(); keysUp = new ArrayList<>(); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrtho(0, 640, 480, 0, 1, -1); glMatrixMode(GL_MODELVIEW); while (!Display.isCloseRequested()) { glClear(GL_COLOR_BUFFER_BIT); checkKeys(); p.draw(); Display.update(); Display.sync(60); } Display.destroy(); } public void checkKeys() { ArrayList<Integer> keys = new ArrayList<>(); keys.add(Keyboard.KEY_A); keys.add(Keyboard.KEY_D); keys.add(Keyboard.KEY_W); keys.add(Keyboard.KEY_S); for (int key : keys) { if (Keyboard.isKeyDown(key)) keysDown.add(key); else keysUp.add(key); } keysDown.removeAll(keysUp); keysUp = new ArrayList<>(); int speed = 4; int dx = 0; int dy = 0; if (keysDown.contains(keys.get(2))) { System.out.println("keyUP"); dy -= speed; } if (keysDown.contains(keys.get(3))) { System.out.println("keyDOWN"); dy += speed; } if (keysDown.contains(keys.get(0))) { System.out.println("keyLEFT"); dx -= speed; } if (keysDown.contains(keys.get(1))) { System.out.println("keyRIGHT"); dx += speed; } //if (keysDown.contains(keys.get(0)) && keysDown.contains(keys.get(1))) dx = 0; //if (keysDown.contains(keys.get(2)) && keysDown.contains(keys.get(3))) dy = 0; p.update(dx, dy); } public static void main(String[] args) { new Main(); } class Man { public int x, y, w, h; public float cR, cG, cB; public Man(int x, int y) { this.x = x; this.y = y; w = 50; h = 50; Random rand = new Random(); cR = rand.nextFloat(); cG = rand.nextFloat(); cB = rand.nextFloat(); } public void draw() { glColor3f(cR, cG, cB); glRecti(x, y, x+w, y+h); } public void update(int dx, int dy) { x += dx; y += dy; } } } That is the code that I am working with. In addition, I am unsure how to compile an executable jar that is using the lwjgl library in addition to slick-util.

• Solr adding document cycle & wait on response issue

  - by user1585896

  I am trying to send http post request to Solr for adding 50000 documents (all individual request one after another in while loop). I am using DefaultHttpClient in java to connect to Solr and when I use execute method on my HttpPost Solr takes 3 to 4 ms to response. I have commit=false, autoCommit=false, autoSoftCommit=false. My question is why it takes that much time to response and why cycle it follows to add new document. Basically I want to send add request but do not want to commit to see how many request can Solr handle without doing any kind of commits(without having to do any disk access). My guess is with above parameter tuned off I should be hitting Solr about 10000 times every second, but my result is 300 times a second. I am generating random data to add in my code.

• Not a statement?

  - by abelenky

  I have a simple little code fragment that is frustrating me: HashSet<long> groupUIDs = new HashSet<long>(); groupUIDs.Add(uid)? unique++ : dupes++; At compile time, it generates the error: Only assignment, call, increment, decrement, and new object expressions can be used as a statement HashSet.Add is documented to return a bool, so the ternary (?) operator should work, and this looks like a completely legitimate way to track the number of unique and duplicate items I add to a hash-set. When I reformat it as a if-then-else, it works fine. Can anyone explain the error, and if there is a way to do this as a simple ternary operator?

• Association in Entity Framework 4

  - by Marsharks

  I have two tables, a problem table and a problem history table. As you can expect, a problem can have many histories associated with it. CREATE TABLE [dbo].[Problem]( [Last_Update] [datetime] NULL, [Problem_Id] [int] NOT NULL, [Incident_Count] [int] NULL ) ALTER TABLE [dbo].[Problem] ADD CONSTRAINT [PK_Problem] PRIMARY KEY CLUSTERED ( [Problem_Id] ASC ) CREATE TABLE [dbo].[Problem_History]( [Last_Update] [datetime] NULL, [Problem_Id] [int] NOT NULL, [Severity_Chg_Flag] [char](1) NULL ) ALTER TABLE [dbo].[Problem_History] ADD [Create_DateTime] [datetime] NOT NULL ALTER TABLE [dbo].[Problem_History] WITH CHECK ADD CONSTRAINT [FK_Problem_History_Problem] FOREIGN KEY([Problem_Id]) REFERENCES [dbo].[Problem] ([Problem_Id]) The problem is when I drag this into an Entity Model, the associations are not included. Any ideas? I would like to point out that the problem history table has no separate key of its own, it shares the problem id

• contain new elements of an "instance" in javascript

  - by iamnotmad

  Hi, so I know there are tons of ways to simulate inheritance and other OO features. I have chosen one to use for my project and am wondering if I can create an instance and add stuff to it and keep it contained (within braces). Consider the following: function BaseClass(){ <this.stuff here> } function SubClass(){ this.superClass = BaseClass(); this.superClass(); <this.other stuff here> } myObj = new SubClass(); so myObj is an instance of SubClass. I can add things to myObj like: myObj.blah = "funtimes"; What I would like is to be able to add stuff to the "instance" and keep it organized in braces much like the constructor. psuedo code like: myObj = new SubClass() { var blah = "funtimes" <more instance specific stuff here> } Is something like this possible? Thanks!

• Is call to function object inlined?

  - by dehmann

  In the following code, Foo::add calls a function via a function object: struct Plus { inline int operator()(int x, int y) const { return x + y; } }; template<class Fct> struct Foo { Fct fct; Foo(Fct f) : fct(f) {} inline int add(int x, int y) { return fct(x,y); // same efficiency adding directly? } }; Is this the same efficiency as calling x+y directly in Foo::add? In other words, does the compiler typically directly replace fct(x,y) with the actual call, inlining the code, when compiling with optimizations enabled?

• Error 1005 when adding a foreign key constraint on mysql table

  Hello, I have a problem when upgrading a django and mysql app with south. I've tried to make a sql-based upgrade with the code generated by the django sqlall command and I have a similar problem. Here is the sql code: CREATE TABLE `programmations_basissupport` ( `id` integer AUTO_INCREMENT NOT NULL PRIMARY KEY, `value` numeric(6, 0) NOT NULL ) ALTER TABLE `programmations_concert` ADD `basis_support_id` integer AFTER program_status_id; ALTER TABLE `programmations_concert` ADD CONSTRAINT `basis_support_id_refs_id_1e4ed8d7` FOREIGN KEY (`basis_support_id`) REFERENCES `programmations_basissupport` (`id`); An error is raised when adding the FK constraint: ERROR 1005 (HY000): Can't create table 'apidev_mnl.#sql-106e_632b00a' (errno: 150) Does anybody have an idea?
