• How to access hidden template in unnamed namespace?

  - by Johannes Schaub - litb

  Here is a tricky situation, and i wonder what ways there are to solve it namespace { template <class T> struct Template { /* ... */ }; } typedef Template<int> Template; Sadly, the Template typedef interferes with the Template template in the unnamed namespace. When you try to do Template<float> in the global scope, the…

• Graphical Sudo for Mac OSX

  - by Johannes

  Hi. I'm designing a little software in java. Don't know the term/definition to what I'm doing, but I'm prompting commands from java to the terminal. Something like this: Process process = Runtime.getRuntime().exec("command"); I've done this before in linux, and I used the gksudo for commands that required root password. Is there any "gksudo"…

• Is there a way to download the rendered view of a google motion-chart as a .png?

  - by Johannes Meier

  I am using Google motion-charts in a web-site developed in python/django. Is there a way to save the rendered view of a google motion-chart as an image (server-side)? For the more basic chart types - such as scatter diagrams - the command chart.download('scatter-random-marker-sizes.png') works fine, but I have not found an equivalent for…

• Correctly Applying an Open Source License

  - by Johannes Rudolph

  My question consists of multiple points that are inherently related, I apologize for that. I tried splitting it up a little more, but I would keep repeating myself. What exactly is required to apply an open source license to a code base that is my Intellectual Property? A lot of Open Source projects include a full copy of the license…

• TFS How does merging work?

  - by Johannes Rudolph

  I have a release branch (RB, starting at C5) and a changeset on trunk (C10) that I now want to merge onto RB. The file has changes at C3 (common to both), one in CS 7 on RB, and one in C9 (trunk) and one in C10). So the history for my changed file looks like this: RB: C5 -> C7 Trunk: C3 -> C9 ->…

• Predefining C Array

  - by Johannes Jensen

  In C, when defining an array I can do the following: int arr[] = {5, 2, 9, 8}; And thus I defined it and filled it up, but how do I define it in my .h file, and then fill it in my .c? Like do something like int arr[]; arr = {5, 2, 9, 8}; I'm pretty new to C, not sure how it would look any suggestions?

• Usage of Assert.Inconclusive

  - by Johannes Rudolph

  Hi, Im wondering how someone should use Assert.Inconclusive(). I'm using it if my Unit test would be about to fail for a reason other than what it is for. E.g. i have a method on a class that calculates the sum of an array of ints. On the same class there is also a method to calculate the average of the element. It is…

• Function with parameter type that has a copy-constructor with non-const ref chosen?

  - by Johannes Schaub - litb

  Some time ago I was confused by the following behavior of some code when I wanted to write a is_callable<F, Args...> trait. Overload resolution won't call functions accepting arguments by non-const ref, right? Why doesn't it reject in the following because the constructor wants a Test&? I expected it to take…

• XMLEncoder and PersistenceDelegate

  - by Johannes Rössel

  I'm trying to use XMLEncoder to write an object graph (tree in my case) to a file. However, one class contained in it is not actually a Java bean and I don't particularly like making its guts publicly accessible. It's accessed more like a list and has appropriate add methods. I've already written a custom…

• C callback functions defined in an unnamed namespace?

  - by Johannes Schaub - litb

  Hi all. I have a C++ project that uses a C bison parser. The C parser uses a struct of function pointers to call functions that create proper AST nodes when productions are reduced by bison: typedef void Node; struct Actions { Node *(*newIntLit)(int val); Node *(*newAsgnExpr)(Node *left, Node *right);…

• Examples of ISO C++ code that is not valid C++/CLI

  - by Johannes Schaub - litb

  I've seen contradictory answers on the internet with regard to whether C++/CLI is a superset of C++ or not. The accepted answer on this question claims that "technically no", but doesn't provide an examples of non-C++/CLI code that conforms to ISO C++. Another answer on that question cites a book…

• Why do C++ streams use char instead of unsigned char?

  - by Johannes Schaub - litb

  I've always wondered why the C++ Standard library has instantiated basic_[io]stream and all its variants using the char type instead of the unsigned char type. char means (depending on whether it is signed or not) you can have overflow and underflow for operations like get(), which will lead to…

• MEMORY(HEAP) vs. InnoDB in a Read and Write Environment

  - by Johannes

  I want to program a real-time application using MySQL. It needs a small table (less than 10000 rows) that will be under heavy read (scan) and write (update and some insert/delete) load. I am really speaking of 10000 updates or selects per second. These statements will be executed on only a few…

  - by Johannes Rössel

  I have an advanced function in PowerShell, which roughly looks like this: function Foo { [CmdletBinding] param ( [int] $a = 42, [int] $b ) } The idea is that it can be run with either two, one or no arguments. However, the first argument to become optional is the…
