Construct NetworkX Graph From Pandas DataFrame

Answer : NetworkX expects a square matrix (of nodes and edges), perhaps* you want to pass it: In [11]: df2 = pd.concat([df, df.T]).fillna(0) Note: It's important that the index and columns are in the same order! In [12]: df2 = df2.reindex(df2.columns) In [13]: df2 Out[13]: Bar Bat Baz Foo Loc 1 Loc 2 Loc 3 Loc 4 Loc 5 Loc 6 Loc 7 Quux Bar 0 0 0 0 0 0 1 1 0 1 1 0 Bat 0 0 0 0 0 0 1 0 0 1 0 0 Baz 0 0 0 0 0 0 1 0 0 0 0 0 Foo 0 0 0 0 0 0 1 1 0 0 0 0 Loc 1 0 0 0 0 0 0 0 0 0 0 0 1 Loc 2 0 0 0 0 0 0 0 0 0 0 0 0 Loc 3 1 1 1 1 0 0 0 0 0 0 0 0 Loc 4 1 0 0 1 0 0 0 0 0 0

Angular 7 Test: NullInjectorError: No Provider For ActivatedRoute

Answer : You have to import RouterTestingModule import { RouterTestingModule } from "@angular/router/testing"; imports: [ ... RouterTestingModule ... ] Add the following import imports: [ RouterModule.forRoot([]), ... ], I had this error for some time as well while testing, and none of these answers really helped me. What fixed it for me was importing both the RouterTestingModule and the HttpClientTestingModule. So essentially it would look like this in your whatever.component.spec.ts file. beforeEach(async(() => { TestBed.configureTestingModule({ declarations: [ProductComponent], imports: [RouterTestingModule, HttpClientTestingModule], }).compileComponents(); })); You can get the imports from import { RouterTestingModule } from "@angular/router/testing"; import { HttpClientTestingModule } from "@angular/common/http/testing"; I dont know if this is the best solution, but this worked for me.

Connecting To Remote SSH Server (via Node.js/html5 Console)

Answer : This is easily doable with modules like ssh2 , xterm , and socket.io . Here's an example: npm install ssh2 xterm socket.io Create index.html : <html> <head> <title>SSH Terminal</title> <link rel="stylesheet" href="/src/xterm.css" /> <script src="/src/xterm.js"></script> <script src="/addons/fit/fit.js"></script> <script src="/socket.io/socket.io.js"></script> <script> window.addEventListener('load', function() { var terminalContainer = document.getElementById('terminal-container'); var term = new Terminal({ cursorBlink: true }); term.open(terminalContainer); term.fit(); var socket = io.connect(); socket.on('connect', function() { term.write('\r\n*** Connected to backend***\r\n'); // Browser -> Backend term.o

Convert .pfx To .cer

Answer : PFX files are PKCS#12 Personal Information Exchange Syntax Standard bundles. They can include arbitrary number of private keys with accompanying X.509 certificates and a certificate authority chain (set certificates). If you want to extract client certificates, you can use OpenSSL's PKCS12 tool. openssl pkcs12 -in input.pfx -out mycerts.crt -nokeys -clcerts The command above will output certificate(s) in PEM format. The ".crt" file extension is handled by both macOS and Window. You mention ".cer" extension in the question which is conventionally used for the DER encoded files. A binary encoding. Try the ".crt" file first and if it's not accepted, easy to convert from PEM to DER: openssl x509 -inform pem -in mycerts.crt -outform der -out mycerts.cer the simple way I believe is to import it then export it, using the certificate manager in Windows Management Console. If you're working in PowerShell you can use something like the follo

Compressing A Folder With Many Duplicated Files

Answer : Best options in your case is 7-zip. Here is the options: 7za a -r -t7z -m0=lzma2 -mx=9 -mfb=273 -md=29 -ms=8g -mmt=off -mmtf=off -mqs=on -bt -bb3 archife_file_name.7z /path/to/files a - add files to archive -r - Recurse subdirectories -t7z - Set type of archive (7z in your case) -m0=lzma2 - Set compression method to LZMA2 . LZMA is default and general compression method of 7z format. The main features of LZMA method: High compression ratio Variable dictionary size (up to 4 GB) Compressing speed: about 1 MB/s on 2 GHz CPU Decompressing speed: about 10-20 MB/s on 2 GHz CPU Small memory requirements for decompressing (depend from dictionary size) Small code size for decompressing: about 5 KB Supporting multi-threading and P4's hyper-threading -mx=9 - Sets level of compression. x=0 means Copy mode (no compression). x=9 - Ultra -mfb=273 - Sets number of fast bytes for LZMA. It can be in the range from 5 to 273. The default value is 32 for normal mode and 64 for maximum

ADB Root Is Not Working On Emulator (cannot Run As Root In Production Builds)

Answer : To enable root access: Pick an emulator system image that is NOT labelled "Google Play". (The label text and other UI details vary by Android Studio version.) Exception: As of 2020-10-08, the Release R "Android TV" system image will not run as root. Workaround: Use the Release Q (API level 29) Android TV system image instead. Test it: Launch the emulator, then run adb root . It should say restarting adbd as root or adbd is already running as root not adbd cannot run as root in production builds Alternate test: Run adb shell , and if the prompt ends with $ , run su . It should show a # prompt. Steps: To install and use an emulator image that can run as root: In Android Studio, use the menu command Tools > AVD Manager . Click the + Create Virtual Device... button. Select the virtual Hardware, and click Next . Select a System Image. Pick any image that does NOT say "(Google Play)" in the Target column. If you dep

Double Border Css Code Example

Example 1: dashed lin in css hr { border : none ; border-top : 1 px dashed #f00 ; color : #fff ; background-color : #fff ; height : 1 px ; width : 50 % ; } Example 2: css border style /* * border-style: solid: A solid, continuous line. none (default): No line is drawn. hidden: A line is drawn, but not visible. this can be handy for adding a little extra width to an element without displaying a border. dashed: A line that consists of dashes. dotted: A line that consists of dots. double: Two lines are drawn around the element. groove: Adds a bevel based on the color value in a way that makes the element appear pressed into the document. ridge: Similar to groove, but reverses the color values in a way that makes the element appear raised. inset: Adds a split tone to the line that makes the element appear slightly depressed. outset: Similar to inset, but reverses the colors in a way that makes the element appear slightly raised. */ /* Example using the typical solid borde

Can Someone Explain Where Applicative Instances Arise In This Code?

Answer : This is the Applicative instance for ((->) r) , functions from a common type. It combines functions with the same first argument type into a single function by duplicating a single argument to use for all of them. (<$>) is function composition, pure is const , and here's what (<*>) translates to: s :: (r -> a -> b) -> (r -> a) -> r -> b s f g x = f x (g x) This function is perhaps better known as the S combinator. The ((->) r) functor is also the Reader monad, where the shared argument is the "environment" value, e.g.: newtype Reader r a = Reader (r -> a) I wouldn't say it's common to do this for the sake of making functions point-free, but in some cases it can actually improve clarity once you're used to the idiom. The example you gave, for instance, I can read very easily as meaning "is a character a letter or number". You get instances of what are called static arrows (see "A

Can Not Start Elasticsearch As A Service In Ubuntu 16.04

Answer : I found the solution for this issue. The solution comes from this discussion thread- Can’t start elasticsearch with Ubuntu 16.04 on elastic's website. It seems that to get Elasticsearch to run on 16.04 you have to set START_DAEMON to true on /etc/default/elasticsearch . It comes commented out by default, and uncommenting it makes Elasticsearch start again just fine. Be sure to use systemctl restart instead of just start because the service is started right after installation, and apparently there's some socket/pidfile/something that systemd keeps that must be released before being able to start the service again. The problem lies on log files, "No java runtime was found." Jul 30 18:28:13 dimik elasticsearch[10266]: [warning] /etc/init.d/elasticsearch: No java runtime was found Here's my solution to the problem. Check elasticsearch init file sudo nano /etc/init.d/elasticsearch search for . /usr/share/java-w
