Example: how to make image responsive bootstrap 4 <img src= "..." class= "img-fluid" alt= "Responsive image" >

Answer : There is an implementation in my TypeScript utilities based on JavaScript GUID generators. Here is the code: class Guid { static newGuid() { return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) { var r = Math.random() * 16 | 0, v = c == 'x' ? r : (r & 0x3 | 0x8); return v.toString(16); }); } } // Example of a bunch of GUIDs for (var i = 0; i < 100; i++) { var id = Guid.newGuid(); console.log(id); } Please note the following: C# GUIDs are guaranteed to be unique. This solution is very likely to be unique. There is a huge gap between "very likely" and "guaranteed" and you don't want to fall through this gap. JavaScript-generated GUIDs are great to use as a temporary key that you use while waiting for a server to respond, but I wouldn't necessarily trust them as the primary key in a database. If you are going to rely on a JavaScript-generated GUID, I wo

Answer : Can I use more the 16 colours in a Windows batch file? No, as most most Windows apps only support 16 colours. However, in the Windows 10 Insiders Build #14931 the Windows Console was updated to support 24-bit RGB true color. Unfortunately as mentioned above most Windows apps cannot make use of this enhancement (yet). However, using Windows Subsystem for Linux (WSL), Linux scripts and tools can use the Console's new 24-bit color support: One of the most frequent requests we receive is to increase the number of colors that the Windows Console can support. We love nothing more than to deliver features you ask for! But rather than just add a few more colors, or limit our console to a mere 256 colors, in Windows 10 Insiders Build #14931, we’ve updated the Windows Console to support full, glorious 24-bit RGB true color! This is actually a little tricky to demo since most Windows apps only support 16 colors at most whereas the Linux world has broadly supported 256 col

Answer : Implementation 1 returns the magnitude of the vector that would result from a regular 3D cross product of the input vectors, taking their Z values implicitly as 0 (i.e. treating the 2D space as a plane in the 3D space). The 3D cross product will be perpendicular to that plane, and thus have 0 X & Y components (thus the scalar returned is the Z value of the 3D cross product vector). Note that the magnitude of the vector resulting from 3D cross product is also equal to the area of the parallelogram between the two vectors, which gives Implementation 1 another purpose. In addition, this area is signed and can be used to determine whether rotating from V1 to V2 moves in an counter clockwise or clockwise direction. It should also be noted that implementation 1 is the determinant of the 2x2 matrix built from these two vectors. Implementation 2 returns a vector perpendicular to the input vector still in the same 2D plane. Not a cross product in the classical sense but c

Answer : You likely have driver corruption issue. You can try to remove all printer driver and reinstall them. A similar thread exists over technet: http://social.technet.microsoft.com/Forums/en/itprovistaprinting/thread/3e47b7b6-00a3-47e1-9e28-e615fbff5f87 but that particular thread is for windows vista so the answer may or may not work. Since it worked, here's the text from the linked document (Originally by Arthur Xie, a Microsoft Employee): Remove a printer Click the "Start" button, type PRINTER in the search box and press Enter. Find the icons of installed printers, and delete them. Right-click on the blank part of the window, and choose "Run as administrator"->"Server Properties". On the Drivers tab, select the listed printers and click the Remove button. Please then select Remove driver and driver package. Open Start menu, input APPWIZ.CPL in the Search box and press ENTER to launch "Programs and Features". Try to rem

Answer : You should try assign GIDSignInButton not to the Button Object from the Object library but to the the View Object instead It's work for me. It will look like this using UIView instead of UIButton. That's because GIDSignInButton is a subclass of UIView, not UIButton. Add to the storyboard / nib a regular UIView and change it's class to GIDSignInButton instead. From google doc: Add a GIDSignInButton to your storyboard, XIB file, or instantiate it programmatically. To add the button to your storyboard or XIB file, add a View and set its custom class to GIDSignInButton. You can create UIButton and then on its action method you can write this code for signing via google: GIDSignIn.sharedInstance().signIn() It works for me, in this way you can customize UIButton according to your requirement and also perform signin by using google

Answer : Currently what's working best for me on linux is the following: epstopdf foo.eps pdf2svg foo.pdf foo.svg I believe the first command is a wrapper for ghostscript, and the second is a wrapper for calls to the Poppler and Cairo libraries. On ubuntu, they're in the packages texlive-font-utils and pdf2svg. Gradients come out looking right, but don't seem to be editable in inkscape. I tried using inkscape and uniconverter for this purpose, and as of Jan 2013, both seemed broken when tested on an example containing nothig but some very simple line art. Inkscape throws errors and can't open the eps file. Uniconverter crashes. Scribus and sk1 may work, but seem awkward and not really suited for this task. Uniconvertor is currently the most convenient option. It's a command-line tool that shares code with the sK1 Project. You won't have to bother cropping the image in sK1 if you use uniconvertor, so it's more automated. Run it like this: uniconvertor befo
