32,670,160 | 0 | <p>The symbol <code>&</code> is the <code>and</code> logical operator. You can use it for multiple conditions in your <code>while</code> loop.</p> <pre><code>while (user_input ~= 256 & user_input ~= 128 & user_input ~= 64) prompt = 'Please enter one of the listed gray levels (256, 128, 64, 32, 16, 8, 4, 2). '; user_input = input(prompt); end </code></pre> <p>As beaker pointed out, what you ask is to ask for input as long as it is not one of the following values : 256, 128 or 64. Using the <code>or</code> logical operator would mean that <code>user_input</code> should be 256, 128 and 64 at the same time to break the loop.</p> <hr> <p>You can also use <a href="http://fr.mathworks.com/help/matlab/ref/ismember.html" rel="nofollow"><code>ismember</code></a>.</p> <pre><code>conditionnal_values = [256, 128 , 64] while ~ismember(user_input, conditionnal_values) prompt = 'Please enter one of the listed gray levels (256, 128, 64, 32, 16, 8, 4, 2). '; user_input = input(prompt); end </code></pre> <hr> <p>An other way to go, proposed by Luis Mendo, is to use <a href="http://fr.mathworks.com/help/matlab/ref/any.html" rel="nofollow"><code>any</code></a></p> <pre><code>conditionnal_values = [256, 128 , 64] while ~any(user_input==conditionnal values) prompt = 'Please enter one of the listed gray levels (256, 128, 64, 32, 16, 8, 4, 2). '; user_input = input(prompt); end </code></pre> <p><code>user_input == conditionnal_value</code> returns an array composed of 1s and 0s depending on if values of <code>conditionnal_values</code> match with <code>user_input</code>. Then any finds if there is at least one <code>1</code> on this array. Then we apply <code>~</code> which is the <code>not</code> operator.</p> |

The paths start at the same node and end in the same node. How can I draw this with d3?</p> <p><a href="https://i.stack.imgur.com/ttriI.jpg" rel="nofollow noreferrer">This is the desired output</a></p> <p>Some nodes repeat themselves in different places. For example D happens after C and it also happens after A. Also C happens after A and after D. The start and end is always the same but everything in between is not.</p> <p>I tried using treant JS and D3 but so far nothing I have done has worked.</p> <p>Thanks</p> |

But if I use the curly braces it works:</p> <pre><code>:math:`\alpha` </code></pre> <p>does not compile</p> <pre><code>:math:`{\alpha}` </code></pre> <p>gives me the symbol I want</p> <pre><code>:math:`{\\alpha}` </code></pre> <p>gives me the word 'alpha' written as adjacent math variables a, l, p, h, a.</p> |

4,730,448 | 0 | <p>I'm not sure php is the right tool here. Why not use something that is closer to the shell environment, like a bash script?</p> <p>The only reason I can imagine you want to use PHP is so you can start the process by clicking a link on a page somewhere, and thereby punch a large hole in whatever security your system supposedly has. But if you really must, then it is still easier to write a script in a more shell friendly language and simply use php as a gateway to invoke the script.</p> |

39,507,229 | 0 | Forms authentication for Web API invalidated by external assembly? <p>We have a site that uses Forms-authentication through a custom MembershipProvider and Web API that we're now having an unexpected problem with. </p> <p>The site uses EPiServer CMS, but I think the problem is general enough that the question can probably be answered without any knowledge of EPiServer. </p> <p>The problem started when we upgraded EPiServer to the latest version - this also gave us a new assembly for their Service API which basically is a REST API for integrating with their CMS that is setup on a specific route on the site automatically - just by including the assembly in the bin-folder. </p> <p>This new version of their Service API uses OWIN and configures their API to use Bearer-authentication and as far as I can understand also ClaimsIdentity, which would be fine except this suddenly also applies to <em>our</em> implementation of Web API, causing the HttpContext.Current.User to be a ClaimsIdentiy that's not authenticated. Removing the Service API-assembly makes it a FormsIdentity again. </p> <p>The Forms-authentication continues to work fine on the website itself, it is just the WebAPI that is affected by this. </p> <p>So we're looking for a way to fix this, any ideas would be greatly appreciated!</p> |

You could replace <code>document.getElementById("submit").style.visibility = "hidden";</code> with <code>$("#submit).hide();</code></p> |

22,508,449 | 0 | <p>I think you are trying to assign the various objects to the top level environment. Functions have their own environments, so assignments there exist only during the evaluation of the functions (which is why you can see the objects when <code>debug</code>ging). As soon as you your function returns, the objects in the body of the function cease to exist.</p> <p>In order to work around that, you can use <code><<-</code> (i.e. <code>Butterfly_data <<- read.csv(...)</code>), as well as anytime you modify those objects within the function.</p> <p>Please keep in mind that <code><<-</code> use is generally discouraged, and there is almost always a better way to do something than using <code><<-</code>.</p> <p>For example, in this case, you could have returned a list with all your objects, and written a separate function that runs through the lists and produces the heads:</p> <pre><code>Extremes <- function(siteno) { # bunch of stuff return(list(Precip=Precip, Tmax=Tmax, Tmin=Tmin)) } data.list <- Extremes("mysiteno") lapply(data.list, head) # view the heads list2env(data.list) # if you really want objects available at top level directly </code></pre> |

3,967,400 | 0 | Create or manipulate EPS files using .NET <p>I have to create thousands of individual EPS (Encapsulated PostScript) files. These files will be printed by a company that uses a Roland printer and software. The printer software only accepts eps files.</p> <p>So this is the procedure I've implemented using a custom vector graphics library:</p> <ol> <li>Create an individual bitmap (this works)</li> <li>Draw a rectangle around the bitmap in a certain named color (the color must be named "CutContour" YMCK (0, 0.9, 0, 0). The color itself isn't important, but the name must be set to "CutContour".</li> <li>Save the graphics in the EPS format</li> </ol> <p>Now, using some custom library I was able to do all the steps I've described, but the library apparently doesn't support color names (spot colors?).</p> <p>Another strategy I tried in my desperation: I've created a working example file in EPS using CorelDraw (I even did it with Adobe Illustrator).</p> <p>Using a hex editor I extracted the first part of the file until the bitmap information and the bottom part after the bitmap. Using both parts I was able to "inject" the individual bitmap and created new "Frankenstein" eps files just by concatenating the parts.</p> <p>I could open these files in CorelDraw, but they must be somehow corrupt, because the company that prints the images can't open them on their machines. Also, I have some other issues with that files. I guess there is some binary information at the end of the file that's somehow related to the bitmap.</p> <ol> <li>Does anybody know some other library or clever way to get the desired result?</li> <li>Does anybody know who I could manipulate the created eps file in order to draw the rectangle using the "CutContour" color name?

2,705,938 | 0 | <p>The bracket <code>[</code> is a <code>test</code> operator, which you can think of as an if statement. This is checking to see if the shell variable RABBITMQ_NODE_IP_ADDRESS is empty. Unfortunately, if you try to compare to an empty string <code>""</code>, the shell eliminates it before it does the test and your binary comparison operator only gets one (or maybe zero) operands. To prevent that error, it is a common practice to concatenate an "x" on each side of the <code>=</code>. Thus, instead of</p> <pre><code>[ "" = "<variable>" ] </code></pre> <p>becoming [ = value ] and yielding an error,</p> <pre><code>[ "X" = "X<variable>" ] </code></pre> <p>becomes [ X = Xvalue ]</p> <p>and the comparison may continue</p> |

18,603,273 | 0 | NodeJS Code Coverage of Automated Tests <p>As part of a custom testing framework for a NodeJS REST API, I'd like to automatically detect when my tests are no longer providing proper coverage by comparing all <em>possible</em> outcomes with what the test suite received. </p> <p>What methods exist for doing this? We can assume that it's being used for a REST API with a list of entry functions (API endpoints) that need coverage analysis, and each entry function will end with a known 'exit function' that responds to the requester in a standard way. </p> <p>Here's what I've found so far:</p> <p><strong>1: Basic solution (Currently implemented)</strong></p> <ul> <li>When writing each REST endpoint, manually create a list of all the possible outcome 'codes' [Success, FailureDueToX, FailureDueToY] for example</li> <li>After the tests have run, ensure every code in the list has been seen by the test suite for each endpoint. </li> </ul> <p><em><strong>Pros:</strong></em> Very basic and easy to use; Doesn't change performance testing times</p> <p><em><strong>Cons:</strong></em> Highly prone to error with lots of manual checking; Doesn't flag any issues if there are 5 ways to 'FailDueToX' and you only test 1 of them. Very basic definition of 'coverage'</p> <p><strong>2: Static analysis</strong></p> <ul> <li>Parse the code into some sort of parse tree and look for all the instances of the 'exit function'</li> <li>Traverse up the tree until an API Endpoint is reached, and add that exit instance to the endpoint as an expected output (needs to keep a record of the stack trace to get there via a hash or similar)</li> <li>When tests are run, the endpoints return the stack trace hash or similar and this is compared to the expected output list.</li> </ul> <p><em><strong>Pros:</strong></em> Automatic; Catches the different branches that may result in the same output code</p> <p><em><strong>Cons:</strong></em> Generating the parse tree is non trivial; Doesn't detect dead code that never gets run; test suite needs to be kept in sync</p> <p><strong>3: Profiling</strong></p> <p>I've done this in the past on Embedded Systems with <a href="http://www.ghs.com/products/safety_critical/gcover.html" rel="nofollow">GreenHills Code Coverage Tools</a></p> <ul> <li>Start up a profiler like <a href="http://blog.nodejs.org/2012/04/25/profiling-node-js/" rel="nofollow">dtrace</a> and record the stack log for each test separately</li> <li>Parse the stack log and assign the 'test' to each line of code</li> <li>Manually analyse the code-with-annotations to find gaps.</li> </ul> <p><em><strong>Pros:</strong></em> Semi Automatic; Gives more information about total coverage to a developer; Can see </p> <p><em><strong>Cons:</strong></em> Slows down the tests; Unable to do performance testing in parallel; Doesn't flag when a possible outcome is never made to happen. </p> <p>What else is there, and what tools can help me with my Static Analysis and Profiling goals? </p> |

I tried to use mDb.execSQL() but that only returns void. Any help on how to do this would be appreciated. The code is:<br> public int getRowNumber(){ return mDb.execSQL("SELECT COUNT(*) FROM notes");} I get an error that says "cannot return void result". </p> |
