In Chrome, when you open a link in a new background tab (e.g middle click), any videos on that page (YouTube etc) will not start to play until you directly visit that tab (bringing it to the foreground). This is is something I make use of quite often, however this behaviour is not the default in Firefox. Thankfully though, due to the great configuration options in Firefox, this can easily be fixed:
Type about:config in the search bar to open up all of the configuration options.
Filter the results by entering autoplay into the search box.
Toggle the preference media.block-autoplay-until-in-foreground to true.
From then on, any videos will not begin until you bring that tab into the foreground. When media is being blocked from playing, a play icon will appear in the tab (similar to the mute button for audio). You can click on this to begin playing without bringing the tab to the foreground.
Similarly to how you can hold shift whilst you right click on a directory within Windows explorer to open a new command prompt at that directory, it is also possible to do the same with the new WSL Bash. This can make it much easier to work with files within explorer from within the WSL as opposed to lengthy cd commands to the relevant mnt.
To add the new context menu item for Bash within explorer, you need to create a new key within the registry and a few new values underneath it:
Open the registry editor by searching for regedit or going through Win+R. You will need admin privileges to open the editor.
(Optional) Backup your registry via File->Export.
Navigate to the key HKEY_CLASSES_ROOT\Directory\Background\shell.
Create a new key called WSL under shell and and another key underneath WSL called command. This should reflect the structure in the cmd key within shell. The newly created structure should be HKEY_CLASSES_ROOT\Directory\Background\shell\WSL\command.
Change the Default value under the WSL key to the value you want to see in the context menu e.g. ‘Bash Prompt Here’.
(Optional) Create a new String value called Icon under the WSL key with a value of %USERPROFILE%\\AppData\\Local\\lxss\\bash.ico. This will make the bash icon appear in the context menu as seen in the screenshot above.
Change the Default value under the command key to cmd.exe /c pushd "%V" && bash.exe.
Exit the editor and test by right clicking the white space within any directory in Windows Explorer.
You should something corresponding to the screenshot. Selecting the new menu item will open up a new WSL Bash prompt starting at the current directory.
Here is the contents of a .reg file you can also use instead of the above. Simply copy the contents into a file with the .reg extension and then double click on it to merge it into your registry.
If you have accidentally committed a password or other sensitive data to your Git repository, make sure to remove it before pushing it to GitHub or making it open source. When working with databases or other external systems, it’s incredibly easy to put a password into a configuration file, commit it and forget about it - only for it to be subsequently completely visible to everyone on the internet thereafter.
Thankfully, there are a few ways to remove private data from your Git repos. The most bare-metal approach would be to use the git-filter-branch command which is able to rewrite your Git history whilst applying filters. It’s a very powerful command and therefore has many configuration options and is quite difficult to use directly.
A much easier solution is to use the BFG Repo Cleaner. This is a separate tool which offers a much faster and simpler method of cleaning your repo of private data or very large files.
To make use of this tool, first make sure you have Java installed and available on the PATH - follow the steps in this post to do so. Then download the .jar file from their site.
Find sensitive data within your repository
If you have a password or other credential that you think you may have accidentally committed into your repo, run the following command to find out. This uses the ‘pickaxe’ option of git log to find revisions in which the number of occurences of a search time has changed.
$ git log -S<password>
From the docs:
-S Look for differences that change the number of occurrences of the specified string (i.e. addition/deletion) in a file.
-G: looks for differences whose added or removed line matches the given regexp, as opposed to -S, which “looks for differences that introduce or remove an instance of string”.
–all: searches over all branches and tags
Remove passwords and private data using BFG
Create a file called passwords.txt, in which place all your passwords or sensitive data.
Run the command $ java -jar bfg.jar --replace-text passwords.txt <your-repo>
More documentation and examples, along with how to remove large files from your repo can found on the BFG project page.
Note: This will completely rewrite your Git history, the hashes or all commits will be re-generated.
Visual Studio Code has now replaced Sublime Text as my editor of choice due to it’s speed and first class support for a number of features that were previously only available through extensions (of varying quality and often outdated). One such example is a live preview of a markdown page - something essential when writing blog posts or pretty much any documentation these days.
Thankfully, Visual Studio Code not only provides native support for Markdown, but also a great live preview of the results as you type - all without any extensions. To enable the live preview within a new editor tab, use the keyboard shortcut Ctrl+Shift+V when any Markdown (.md) file is open. This works, but it’s much better to have the live preview of the HTML in a split editor so you can see it as you type. VS Code allows you to do this through the shortcut Ctrl+K V. Alternatively, for either of these options you can go through the Command Palette Ctrl+Shift+P and select either of the ‘Markdown Preview’ options.
As of version 1.9, the markdown preview and editor window both scroll in sync. The preview window now loads in local files and you can also now double click on any element within the preview to jump directly to the corresponding line in the editor tab.
Spelling and grammar checking isn’t currently available within Visual Studio Code out of the box (hopefully this will also be added in a future update). There is however a great extension available on the marketplace which does a great job (when the API it relies on is up).
Thanks to the awesomeness that is the WSL Windows Subsystem for Linux, you can now install and use a load of tools on Windows just as you would do under Linux. Previously I used to run Jekyll (running under Ruby) solely through a Unix based environment - creating new blog posts through a system of SSH and SFTP. Ruby development on Windows has never really been that great, but now the whole process has got much easier - run everything locally through the WSL layer.
The first step is to install Ruby. Following the instructions from their site:
