Answer : There's already an issue reporting this error message. The workaround until the next release is to install glob for the project ( npm install --save glob ) Regarding the commands, according to their repository under Generating and serving an Angular2 project via a development server the commands are as follow ng new ponyracer : This command will create a project named ponyracer (a folder named ponyracer with all the set up in it). ng serve : This command will run the live reload server to serve the application so you can see it in your browser. PS : If you test the solution suggested in the issue it would be nice of you to report if it worked or not. PS2 : I tested now (I fixed my error) and I cannot reproduce your error. I'm using node v5.5.0 and npm v3.7.3. Can you specify which node and npm versions are you using? I had the same error on Windows 10, D:\Code\AngularJS>ng new greetings-ac Cannot find module 'glob' Error: Cannot find m

Answer : Historically, the first extensions used for C++ were .c and .h , exactly like for C. This caused practical problems, especially the .c which didn't allow build systems to easily differentiate C++ and C files. Unix, on which C++ has been developed, has case sensitive file systems. So some used .C for C++ files. Other used .c++ , .cc and .cxx . .C and .c++ have the problem that they aren't available on other file systems and their use quickly dropped. DOS and Windows C++ compilers tended to use .cpp , and some of them make the choice difficult, if not impossible, to configure. Portability consideration made that choice the most common, even outside MS-Windows. Headers have used the corresponding .H , .h++ , .hh , .hxx and .hpp . But unlike the main files, .h remains to this day a popular choice for C++ even with the disadvantage that it doesn't allow to know if the header can be included in C context or not. Standard headers now have no extension

Answer : Maybe this is the picture you are looking for. I refer to a path tracing the oriented edge as a a a , and its inverse as a − 1 a^{-1} a − 1 . Note that every continuous path on the dunce cap (any CW-complex really) can be continuously deformed to trace only edges (of the given CW-structure). This should be somewhat visually intuitive, by straightening your path along edges, vertex to vertex. Thus if the path a a a is trivial, so is any other path (do you see why?). A comment as to what deformations are allowed - you are free to push your path anyway you want, and over edges (reemerging on any of the copies of the edge, noting orientations). This is what happens between the first and the second image. The one important rule is that you CANNOT ever move the basepoint (=initial and final point of your path). Note that I did not move the basepoint passing from the first to the second picture, as the three corners of the triangle are literally the same point of the dunce cap.

Defined in header <stdio.h> void perror ( const char * s ) ; Prints a textual description of the error code currently stored in the system variable errno to stderr . The description is formed by concatenating the following components: the contents of the null-terminated byte string pointed to by s , followed by ": " (unless s is a null pointer or the character pointed to by s is the null character) implementation-defined error message string describing the error code stored in errno , followed by '\n' . The error message string is identical to the result of strerror ( errno ) . Parameters s - pointer to a null-terminated string with explanatory message Return value (none). Example # include <stdio.h> int main ( void ) { FILE * f = fopen ( "non_existent" , "r" ) ; if ( f == NULL ) { perror ( "fopen() failed" ) ; } else { fclose

Example 1: 20 minute timer for good eyesight every 20 minutes look out the window at something 20 feet away for 20 seconds Example 2: 20 minute timer For the 20/20/20 rule you can also close your eyes for 20 seconds and get the same results because it relaxes the mucles in your eyes.

Answer : One advantage that no one else has pointed out is that binary search tree allows you to do range searches efficiently. In order to illustrate my idea, I want to make an extreme case. Say you want to get all the elements whose keys are between 0 to 5000. And actually there is only one such element and 10000 other elements whose keys are not in the range. BST can do range searches quite efficiently since it does not search a subtree which is impossible to have the answer. While, how can you do range searches in a hash table? You either need to iterate every bucket space, which is O(n), or you have to look for whether each of 1,2,3,4... up to 5000 exists. (what about the keys between 0 and 5000 are an infinite set? for example keys can be decimals) Remember that Binary Search Trees (reference-based) are memory-efficient. They do not reserve more memory than they need to. For instance, if a hash function has a range R(h) = 0...100 , then you need to allocate an array of

Example: how do you make a list that lists its items with squares? css ul .b { list-style-type : square ; }

Example: css opacity example .opacity30 { opacity : 0.3 ; filter : alpha ( opacity= 30 ) ; /* For IE8 and earlier */ }
