This uses the Dropbox Java SDK to create a shared link for a file at the Dropbox path /test.txt: try { SharedLinkMetadata sharedLinkMetadata = client.sharing().createSharedLinkWithSettings("/test.txt"); System.out.println(sharedLinkMetadata.getUrl()); } catch (CreateSharedLinkW...

This example uses the Dropbox .NET library to get a shared link for a file, either by creating a new one, or retrieving an existing one: SharedLinkMetadata sharedLinkMetadata; try { sharedLinkMetadata = await this.client.Sharing.CreateSharedLinkWithSettingsAsync (path); } catch (ApiException...

On Windows you can install Scollector as a service using the -winsvc="install" flag. On Mac and Linux you must manually create a service or init script. For example here is a basic systemd unit file: #Scollector unit file saved to /etc/systemd/system/scollector.service [Unit] Descriptio...

#Example of a PowerShell external collector. See http://bosun.org/scollector/external-collectors for details #This file should be saved in C:\Program Files\scollector\collectors\0\mymetrics.ps1 since it is a continuous output script #scollector.toml should have ColDir = 'C:\Program Files\scollecto...

The following can be saved as main.go. After you update the EDITME settings and build the executable it can be used as a continuous external collector. package main import ( "fmt" "log" "net/url" "strconv" "time" &...

The following Go file can be compiled into a continuous external collector that will query a MSSQL server database that uses the StackExchange.Exceptional schema.

In classes, super.foo() will look in superclasses only. If you want to call a default implementation from a superinterface, you need to qualify super with the interface name: Fooable.super.foo(). public interface Fooable { default int foo() {return 3;} } public class A extends Object impl...

In case you have accidentally commited a delete on a file and later realized that you need it back. First find the commit id of the commit that deleted your file. git log --diff-filter=D --summary Will give you a sorted summary of commits which deleted files. Then proceed to restore the file b...

To restore a file to a previous version you can use reset. git reset <sha1-of-commit> <file-name> If you have already made local changes to the file (that you do not require!) you can also use the --hard option

To recover a deleted branch you need to find the commit which was the head of your deleted branch by running git reflog You can then recreate the branch by running git checkout -b <branch-name> <sha1-of-commit> You will not be able to recover deleted branches if git's garbage col...

string s = "Foo"; string paddedLeft = s.PadLeft(5); // paddedLeft = " Foo" (pads with spaces by default) string paddedRight = s.PadRight(6, '+'); // paddedRight = "Foo+++" string noPadded = s.PadLeft(2); // noPadded = "Foo" (original string...

Some regex flavors (Perl, PCRE, Oniguruma, Boost) only support fixed-length lookbehinds, but offer the \K feature, which can be used to simulate variable-length lookbehind at the start of a pattern. Upon encountering a \K, the matched text up to this point is discarded, and only the text matching th...

Variable substitutions should only be used inside double quotes. calculation='2 * 3' echo "$calculation" # prints 2 * 3 echo $calculation # prints 2, the list of files in the current directory, and 3 echo "$(($calculation))" # prints 6 Outside of doubl...

The above type handler can be installed into SqlMapper using the AddTypeHandler method. SqlMapper.AddTypeHandler<IHtmlString>(new IHtmlStringTypeHandler()); Type inference allows you to omit the generic type parameter: SqlMapper.AddTypeHandler(new IHtmlStringTypeHandler()); There's als...
