Answer : There are multiple issues... The selector $('.nav li') does nothing because you have no .nav class used anywhere in the markup. It should be $('.navbar-nav .nav-link'). You have style="color:white" on the links which will override any changes you make with the active class. You have no CSS for the active class, and by default Bootstrap active class on navbar-dark is going to be white. What color are you trying to set? Set active in the nav-link instead of the li, .navbar-dark .nav-item > .nav-link.active { color:white; } $('.navbar-nav .nav-link').click(function(){ $('.navbar-nav .nav-link').removeClass('active'); $(this).addClass('active'); }) Demo: https://www.codeply.com/go/I3EjDb74My

Answer : UTU = Universally throughput unlimited There exist UTU balancers for 3, 4, and 5 belts, and likely for any number of belts . Examples are given in this Jupyter notebook, along with a Python implementation of an iterative algorithm for computing the flow for any set of belts and splitters . I will quote some of the notebook here for those who don't wish to follow the link. I refer to splitters as junctions, since that's how they really function. Each belt is composed of unit length segments, referred to in the game as tiles. In the model, we imagine each belt flowing from left to right along coordinate direction x x x and each junction uniting two belts at the left edge of a given tile. Note that some balancers used in practice contain loops and could not be represented by our model without an infinite length belt. The state of a belt tile is represented by a density 0 ≤ ρ ≤ 1 0 \le \rho \le 1 0 ≤ ρ ≤ 1 and a velocity 0 ≤ v ≤ 1 0 \le v \le 1 0 ≤ v ≤ 1 . T

Answer : (updating @ÁlvaroG.Vicario answer and comments, and complementing this answer... This is a Wiki, please edit to enhance ) Example: for CSS3 (and HTML5) there are new explicit rules, as " font-face property must be case-insensitive".[2] Context W3C interoperating standards, mainly XML, HTML, CSV and CSS. CSS general rules CSS2 (a W3C standard of 2008) fixed basic conventions about "Characters and case", and CSS3 (a W3C standard for 2015) added something more. By default "all CSS syntax is case-insensitive (...)" [1] There are exceptions , "(...) except for parts that are not under the control of CSS"[1] 2.1. element names are case-sensitive in HTML5 (?) and XML, but case-insensitive in HTML4. 2.2. identifiers (including element names, classes, and IDs in selectors) are case-sensitive. HTML attributes id and class , of font names, and of URIs lies outside the scope of the CSS specification. .... The Case

Answer : After my initial struggle with the link and controller functions and reading quite a lot about them, I think now I have the answer. First lets understand , How do angular directives work in a nutshell: We begin with a template (as a string or loaded to a string) var templateString = '<div my-directive>{{5 + 10}}</div>'; Now, this templateString is wrapped as an angular element var el = angular.element(templateString); With el , now we compile it with $compile to get back the link function. var l = $compile(el) Here is what happens, $compile walks through the whole template and collects all the directives that it recognizes. All the directives that are discovered are compiled recursively and their link functions are collected. Then, all the link functions are wrapped in a new link function and returned as l . Finally, we provide scope function to this l (link) function which further executes the wrapped link functions

Answer : Instead of justify-content to center content you could add additional columns before and after your content, both with 1fr . Then position the first div and the div after .line to the start at the second column. Fiddle * { box-sizing: border-box; } .outer { width: 80%; margin: 0 auto; } .wrapper { border: 2px solid #f76707; border-radius: 5px; background-color: #fff4e6; display: grid; grid-template-columns: 1fr repeat(3, auto) 1fr; } .wrapper>div:not(.line) { border: 2px solid #ffa94d; border-radius: 5px; background-color: #ffd8a8; padding: 1em; color: #d9480f; } .wrapper > div:first-of-type, .line + div { grid-column: 2; } .line { grid-column: 1 / -1; height: 1px; background: black; } <div class="outer"> <div class="wrapper"> <div>1111111</div> <div>222</div> <div>3333333333</div> <div class="line"></div>

Answer : Many system calls will report the EINTR error code if a signal occurred while the system call was in progress. No error actually occurred, it's just reported that way because the system isn't able to resume the system call automatically. This coding pattern simply retries the system call when this happens, to ignore the interrupt. For instance, this might happen if the program makes use of alarm() to run some code asynchronously when a timer runs out. If the timeout occurs while the program is calling write() , we just want to retry the system call (aka read/write, etc). the answers here are really good and i want to add some internal details : System calls that are interrupted by signals can either abort and return EINTR or automatically restart themselves if and only if SA_RESTART is specified in sigaction(2) and the one responsible for this task is the restart_block which used to track information and arguments for restarting system calls

Answer : You should probably take a look at the rsync-related tools: rdiff and rdiff-backup . The rdiff command lets you produce a patch file and apply it to some other file. The rdiff-backup command uses this approach to deal with entire directories, but I'm guessing you're working with single-file disk images, so rdiff will be the one to use. xdelta can do everything you want. Fair warning though, if your images aren't very similar, you can end up with a very large patch, because xdelta uses half of the defined memory buffer for finding differences. More information is available at the TuningMemoryBudget wiki page. Increasing the buffer size may help out quite a bit. bsdiff is another option, but it's very RAM hungry and completely inappropriate for anything the size of a disk image. bsdiff is quite memory-hungry. It requires max(17*n,9*n+m)+O(1) bytes of memory, where n is the size of the old file and m is the size of the new file. bspatch

Answer : On opening the developer tools, with the developer tools window in focus, press F1 . This will open a settings page. Check the "Auto-open DevTools for popups". This worked for me. UPDATE 2: See this answer . - 2019-11-05 You can also now have it auto-open Developer Tools in Pop-ups if they were open where you opened them from. For example, if you do not have Dev Tools open and you get a popup, it won't open with Dev Tools. But if you Have Dev Tools Open and then you click something, the popup will have Dev-Tools Automatically opened. UPDATE: Time has changed, you can now use --auto-open-devtools-for-tabs as in this answer – Wouter Huysentruit May 18 at 11:08 OP: I played around with the startup string for Chrome on execute, but couldn't get it to persist to new tabs. I also thought about a defined PATH method that you could invoke from prompt. This is possible with the SendKeys command, but again, only on a new instance. And DevTools do

Answer : Yes. It is possible to jump to a specific stepper by using selectedIndex property of the MatStepper . Also, MatStepper exposes public methods next() and previous() . You can use them to move back and forth. In your template: Add an id to your stepper e.g. #stepper . Then in your goBack() and goForward() methods, pass the stepper id: <mat-horizontal-stepper #stepper> <!-- Steps --> </mat-horizontal-stepper> <!-- second option --> <div> <button (click)="goBack(stepper)" type="button">Back</button> <button (click)="goForward(stepper)" type="button">Next</button> </div> .. and in your typescript: import { MatStepper } from '@angular/material/stepper'; goBack(stepper: MatStepper){ stepper.previous(); } goForward(stepper: MatStepper){ stepper.next(); } Link to stackblitz demo . You can also use ViewChild to get a reference to
