TikZ provides syntax similar to DOT which you can use to tighten up your graph drawing code considerably. \documentclass{standalone} \usepackage{tikz} \usetikzlibrary{graphs,quotes,arrows.meta} \begin{document} \begin{tikzpicture} \graph[nodes={draw,circle},edges={-{Stealth[]}}] { ...

TikZ implements several algorithms for automatic graph layouts (requires LuaLaTeX). \documentclass{article} \usepackage{tikz} \usetikzlibrary{graphs,graphdrawing,quotes} \usegdlibrary{force} \begin{document} \begin{tikzpicture} \graph[spring layout] { A -> ["1"...

Thorup's algorithm for single source shortest path for undirected graph has the time complexity O(m), lower than Dijkstra. Basic ideas are the following. (Sorry, I didn't try implementing it yet, so I might miss some minor details. And the original paper is paywalled so I tried to reconstruct it fr...

ls shows files and directories in present working directory. (if no arguments are passed.) (It doesn't show hidden files which starts with . by default.) user@ubuntu14:/usr$ ls bin games include lib lib32 local sbin share src To see all files (hidden files/folders also). Use ls -a OR l...

For Adding this to project you can find official doc easily but in this example I'm going to highlight some of the key areas to be taken care of. Step 1 :- Add google service dependencies { ... compile 'com.google.android.gms:play-services-appindexing:9.4.0' ... } Step...

For simple multi-threaded code, using synchronization is acceptable. However, using synchronization does have a liveness impact, and as a codebase becomes more complex, the likelihood goes up that you will end up with Deadlock, Starvation, or Livelock. In cases of more complex concurrency, using A...

type Meter = Double This simple approach has serious drawbacks for unit handling as every other type that is a Double will be compatible with it: type Second = Double var length: Meter = 3 val duration: Second = 1 length = duration length = 0d All of the above compiles, so in this case un...

An alternative to forever on Linux is nohup. To start a nohup instance cd to the location of app.js or wwwfolder run nohup nodejs app.js & To kill the process run ps -ef|grep nodejs kill -9 <the process number>

You need Node Package Manager to install the project dependencies. Download node for your operating system from Nodejs.org. Node Package Manager comes with node. You can also use Node Version Manager to better manage your node and npm versions. It is great for testing your project on different node...

You can also set multiple sort descriptors, to sort by one attribute within another. For example, return all entries ordered by date, and by name within each date: let fetchRequest = NSFetchRequest(entityName: "NAME_OF_ENTITY") let sortDescriptor1 = NSSortDescriptor(key: "name"...

You can set the path to bcomp.exe git config --global difftool.bc3.path 'c:\Program Files (x86)\Beyond Compare 3\bcomp.exe' and configure bc3 as default git config --global diff.tool bc3

The keywords can also create scopes in order to (un)check multiple operations. short m = 32767; short n = 32767; checked { int result1 = (short)(m + n); //will throw an OverflowException } unchecked { int result2 = (short)(m + n); // will return -2 }
