• Where happens merging in SVN - on the client or server?

  - by Malcolm Frexner

  At my company we evaluate working with feature branches. We want to use mergeinfo to track merging. I have issues in some of our tested projects where merging a trunk that has only little changes into branch leads to lots of changed files because of the changed mergeinfo. I read that this behaviour improoved between version 1.5 and 1.6. Does this mean if I update the SVN - server from 1.5.6 to 1.6 I can expext some improvements when merging, or does this depend on the client (which is 1.6.11)?

• [org-mode]: repeating task in every Mon, Wed, Fri at 18:00, need help with sexp.

  - by zeroDivisible

  Hello, As I had written in title, I need a little help with improvement of this sexp: * TODO remeber about thingie. SCHEDULED: <%%(or (= 1 (calendar-day-of-week date)) (= 3 (calendar-day-of-week date)) (= 5 (calendar-day-of-week date)))> Now it shows itself in the following days, but I would like to change two things about it: How can I also schedule on specific hours (i.e. 18:00 - 20:00) in the following days How can I made this task repeat itself, just like it repeats itself with <2010-05-13 Wed +1w> (by repetition I mean something like it automatically logs the closing date and time and comes back to the TODO state). I will be grateful for any help. Best regards, Mike.

• Help constructing query - Compare columns and replace numbers

  - by Tommy

  I have a feeling that this query is pretty easy to construct, I just can't figure it out. I want to replace all numbers in table X column C, with numbers in table Z column A, where numbers from table X column C matches numbers in table Z column B. I hope that makes sense. Perhaps a little background information will make it clearer. I've converted from one CMS to another, and the module I used to convert mapped the ids to the new database. Table X column A is the new id's. Table X column B is the old id's. Table Z is the table for an image gallery that I migrated, and column C contains the id's of the images owners. Can anyone crack this nut?

• Random walk- Brownian Motion

  - by Sam

  I've been assigned the project of creating a simple console app. that models brownian motion in a 2D plane. I wasn't given much information on how to do so (and I'm hoping that it's a pretty popular assignment so that I could get some insight) just that it relies on random number generation. I researched brownian motion for a little bit and saw some formulas that looked complicated, but by the description is just seems to have to move randomly within a certain number interval. Can anyone clarify? Am I to create a program that continually creates a random number in an interval and then modify the particles "x" and "y" coordinate or is there more to it? Thanks for any help.

• different for loops java

  - by Ayrton

  I'm having some difficulties with the following problem: I'm making a little game where you're at a specific spot and each spot has each some possible directions. The available directions are N(ord),E(ast),S,W . I use the function getPosDirections to get the possible directions of that spot. The function returns the directions into an ArrayList<String> e.g. for spot J3: [E,W] Now the game goes like this: 2 dice will be rolled so you get a number between 2 and 12, this number represents the number of steps you can make. What I want is an ArrayList of all the possible routes e.g.: I throw 3 and I'm currently at spot J3: [[E,N,E],[E,N,S],[E,S,E],[E,S,S],[W,N,E],[W,N,S],[W,S,E],[W,S,S]] How would obtain the last mentioned Array(list)?

• Password protect web pages on Windows CE 6

  - by Chris

  I am using the default web server for WinCE 6 and wish to password protect certain folders. The default VROOT /remoteadmin/ is password protected, and this works but my configuration doesn't work. I have tried mimicking these settings on my own folders but to little success. Here is how one looks: In the HKLM\Comm\HTTPD\VROOTS key I have created a subkey called /web/configuration (this folder actually exists on the box). The following values are in this key A = 1 DefaultPage = config.html Path = /hard disk/webroot/web/configuration/ UserList = ADMIN This is nigh on identical to the settings in /RemoteAdmin/ but /RemoteAdmin/ requests a password and /web/configuration doesn't (even after reboot).

• Accessing hard-coded data in a C# application.

  - by haymansfield

  I'm trying to avaid hardcoding in a .net 2.0 soon to be 3.5 application. I have a large enumneration which I wish to map 1 to 1 to a set of strings. Each enumerated value will also map to 1 of 2 values indicating an action. The existing code does this with a big switch statement but this seems ugly to me. Is there a better way of storing and accessing the data? I've thought about resx files but when you consider that the designer file contains just as many hardcoded values it seems a little pointless. Is embedding an xml file in the assembly a good idea? Is a big switch statement not as bad as it seems? Is there a better solution?

• Any tips on switching from bash to zsh if often using shell inside of emacs?

  - by justingordon

  Related to this question: Advantages and disadvantages between zsh and emacs' (e)shell, I've read some great things about zsh, when using M-x shell, my familiar emacs shell seemed like it would need some customizations. I also use evil-mode in shell mode, so that means I use vi keystrokes for shell editing. Took a little while to get accustomed to this, but I really like it. Any advice or tips on going from bash to zsh if one uses emacs? Or better off adding the file completion mentioned in this question: Worth switching to zsh for casual use?.

• /form making table go odd

  - by noryb009

  I have a table (3x3) that counts "< /form" as space in IE. The code for 1 td looks like: <style type="text/css"> table { border-width: 0px; border-collapse: collapse; padding: 0px; } td, th { padding: 0px; } </style> <table><tr><td><form name="form" action="index.php" method="post"><input type="hidden" name="from" value="a" /><input type="image" src="pic1.gif" alt="1" name="submit" value="submit" /></form></td> There is no spaces anywhere outside the tags. Inside the td, there is a form, with a hidden field and a picture. Firefox shows only the picture, but IE has spaces between the rows. I did a little debugging, and found it was from the /form. Does anyone know a fix to this?

• Generating Fibonacci series in F#

  - by photo_tom

  I'm just starting to learn F# using VS2010 and below is my first attempt at generating the Fibonacci series. What I'm trying to do is to build a list of all numbers less than 400. let fabList = let l = [1;2;] let mutable a = 1 let mutable b = 2 while l.Tail < 400 do let c = a + b l.Add(c) let a = b let b = c My first problem is that on the last statement, I'm getting an error message "Incomplete structured construct at or before this point in expression" on the last line. I don't understand what I'm doing wrong here. While this seems to be an obvious way to build the list in a fairly efficient way (from a c++/C# programmer), from what little I know of f#, this doesn't seem to feel to be the right way to do the program. Am I correct in this feeling?

• What format is your documentation in?

  - by Ek0nomik

  I am going to be writing documentation for two web services that I developed, and I started wondering what people on here do for documentation. Do you create it in an HTML file so it can be viewed in the browser? Word document? Wiki? What do you guys/gals use? I was originally leaning towards creating an HTML page since it seems a little more open and friendly than a word document. Plus I can use the prettify javascript to make code samples look nice. Our company has a Sharepoint though, so an HTML file may not be the best choice given that most documentation is put up in spreadsheets and word documents.

• What is the best signature for overloaded arithmetic operators in C++?

  - by JohnMcG

  I had assumed that the canonical form for operator+, assuming the existence of an overloaded operator+= member function, was like this: const T operator+(const T& lhs, const T& rhs) { return T(lhs) +=rhs; } But it was pointed out to me that this would also work: const T operator+ (T lhs, const T& rhs) { return lhs+=rhs; } In essence, this form transfers creation of the temporary from the body of the implementation to the function call. It seems a little awkward to have different types for the two parameters, but is there anything wrong with the second form? Is there a reason to prefer one over the other?

• undo or reverse argsort(), python

  - by Vincent

  Given an array 'a' I would like to sort the array by columns "a.sort(axis=0)" do some stuff to the array and then undo the sort. By that I don't mean re sort but basically reversing how each element was moved. I assume argsort() is what I need but it is not clear to me how to sort an array with the results of argsort() or more importantly apply the reverse/inverse of argsort() Here is a little more detail I have an array a, shape(a) = rXc I need to sort each column aargsort = a.argsort(axis=0) # May use this later aSort = a.sort(axis=0) now average each row aSortRM = asort.mean(axis=1) now replace each col in a row with the row mean. is there a better way than this aWithMeans = ones_like(a) for ind in range(r) # r = number of rows aWithMeans[ind]* aSortRM[ind] Now I need to undo the sort I did in the first step. ????

• UITableView animations for a "lazy" UI design?

  - by donuts

  I have a UITableViewController that allows the user to perform editing tasks. Now, once a user has committed his change, the table view doesn't directly change the model and updates the table, rather "informs" the model what the user wants to do. The model in turn updates accordingly and then posts a notification that it has been changed. As far as I've seen, I need to begin/end updates on the tableview and in between change the model to its' final form. My changes though, are asynchronous and cannot guarantee to update the model before 'tableview endupdates' is called. Currently, each time I receive a 'model did change' notificaiton, I reload the entire table. So, how can I really make cell animations (delete/insert) work? Should the model fire a notification for each little change instead of the entire table?

• Split Entire Hash Range Into n Equal Ranges

  - by noxtion

  Hello. I am looking to take a hash range (md5 or sha1) and split it into n equal ranges. For example, if n=5, the entire hash range would be split by 5 so that there would be a uniform distribution of key ranges. I would like n=1 to be from the beginning of the hash range to 1/5, 2 from 1/2 to 2/5, etc all the way to the end. I am new to hashing and a little bit unsure of where I could start on solving this for a project. Any help you could give would be great.

• Robust Way of Selecting All Text in Textbox

  - by Emil

  I'm trying to have the content of the an HTML textbox be selected fully onFocus. I know the simple solution of putting a onfocus="this.select()" on the component but this is not a good solution because if a user double clicks into the area the selection is lost and in browsers like chrome it is rarely working like it should and just reverts into input form. I have searched on Google for a little while and can't find a good solution, most suggestions are of this simple solution. What I would like it is that the selection inside the textbox not change once selected and if possible the user should not be able to edit the content of the textbox, for example if you have used AdSense when you grab code from AdSense the selection never changes and your unable to alter the code in the textbox. Any solutions would be appreciated.

• Porting Windows C++ to Standard (Linux) C++ - WSAGetLastError()

  - by Donal Rafferty

  I am currently porting some Windows mobile C++ code to standard C++. So I am trying to find alternatives for windows specific functions. I have had very little luck in finding a standard C++ function that can help me replace the WSAGetLastError() windows specific function. WSAGetLastError() returns error numbers for errors that occur with sockets in windows. So I was wondering if anyone was aware of a way to replace this function in standard c++? A way to get different error numbers for different outcomes of connecting/dissconection a socket would be sufficent.

• Calling Google's Custom Search API via Python

  - by user353829

  I am writing in Python a module that will query Google's Custom Search API and return all listings of domain 'example.com' I Have been reading instructions at https://code.google.com/apis/customsearch/v1/getting_started.html and am a little stumped at the moment. Are my assumptions listed below correct? For example, to search for results that has 'example.com' in the URL, the query is: *'https://www.googleapis.com/customsearch/v1?key=my_key&cx=017576662512468239146:omuauf_lfve&q=site:example.com*' *key=my_key*: value of key given by google cx=017576662512468239146: name of the search engine (google)? *omuauf_lfve*: I have no idea what this is q=site:example.com: This should return all results with 'example.com'; e.g. www.a.example.com, b.example.com, example .com

• Using PHP to determine if a remote file has been replaced?

  - by Rob

  I have a MySQL database with some URLs in it. One URL per row. Each URL has my script on it. What I am wanting to do, is check if the file is still there via a PHP script. Not check if it 404'd, but rather check if it has been modified or replaced. Is this possible? If so, how would it be accomplished? I was thinking making the remote file echo some string, and having the local file check the page for that string, but that seems a little inefficient and sloppy.

• Can I learn the iPhone SDK and complete an app by September?

  - by Kuro

  Hi everyone, I'm wondering if it's realistically possible to learn the iPhone SDK and complete an app by the end of this summer. The app shouldn't be too difficult, it would just interact with my site's API and essentially just fetch, create, and edit resources. I already have a little experience with the SDK (and I'm comfortable with Objective-C), so I'm not completely new to it. Although here I things I don't know how to do and what I'd need to learn: Log in to my site using basic http authentication and store the user's username/password for all future requests Implement a toolbar at the bottom to navigate between different views Fetch and parse xml into list items Do POST/PUT requests to create/edit a resource on my server Are there any good resources available to learn how to do those tasks above? Thanks!

• Is JSONRequest a global Javascript object ?

  - by Anth0

  My goal is to asynchronously call a URL via POST request (REST Webservice) to increment a statistic on one of my object. I am a newby web developper and I discovered JSON yesterday. Since JSON seems a lot popular and handy I went to www.json.org and discovered a JSONRequest object which seems to able one to send POST/GET request asynchronously but I can't get it work. Is it a global Javascript object or do I need to add some files ? I am a little bit confused since I've found a Firefox plugin extension for JSONRequest but I don't understand its purpose.

• How do I display each view once as they are loaded, in Android?

  - by Joe Masilotti

  I have an Android application that works off of a smaller database, around 300 entries. To view the database, I have created a custom view that contains individual rows of data. Then I query the database, and add each line to a newly created custom view. The problem is that it takes a little white for all of this to be created/loaded, so when you open the application, it sits for a few seconds. How can I load one line of data, then display it, then the next, append it, etc.?

• SQL Query, return value from table with no join

  - by jdenomme19

  I'm hoping for an idea on the best way to approach what I'm trying to do. I have a table with a list of transactions. Each transactions has a PostDate in DateTime format. I have another table holding the fiscal period values. This table has the following columns; FiscalYear, FiscalMonth, StartDate, EndDate. I'm trying to write a query that will return all values from my transactions table, along with the FiscalYear and FiscalMonth of the PostDate. So I guess I'm just trying to return the FiscalYear and FiscalMonth values when the PostDate falls between the StartDate and EndDate. I've tried using a Subbuery, but I have little experience with them and kept returning an error message that the subquery was returning more than 1 value. Help would be appreciated SELECT Transactions.PostDate, Transactions.TranKey, Transactions.CustKey, (SELECT FiscalPeriod.FiscPer FROM FiscalPeriod WHERE (Transactions.PostDate > CONVERT(Datetime, FiscalPeriod.StartDate, 102)) AND (Transactions.PostDate < CONVERT(DATETIME, FiscalPeriod.EndDate, 102))) AS FisPer FROM Transactions

• Get data from Joomla jos_users table

  - by RobertR

  Hello, world! I'm trying to build a little bit advanced users system using Joomla, but I stuck at one spot. I added new field on Joomla's jos_users table, but when I wanted to get that field out, like "echo" - it didn't worked at all. Any other data, even password field I can get without problems. Of course, I added new value in /var/www/<project>/libraries/joomla/user/user.php like this after line 40. /** * The users address name * @var string */ var $address = null; What might be the problem here? Or what I did wrong, or what I didn't do at all? Thanks for replies! Cheerio
