Renaming Terminator Tabs Under XFCE4

Posted on by rchapin

Sometimes I need to have quite a few tabs open in a terminal window. For some reason, under XFCE4 when I press CTRL+Alt+A, which is defined as the keyboard shortcut to rename a tab, it hides the window.

The only way that I was able to get it to work was to re-label the shortcut to CTRL+Alt+Z under PreferencesKeybindings in Terminator.→ Continue reading “Renaming Terminator Tabs Under XFCE4”

Configuring VSCode to Use Build Tags in GoLang to Separate Integration and Unit Test Code

Posted on by rchapin

One of the ways to separate unit and integration test code in golang is to use build tags.

A TLDR; on build tags is that it is a way to tell the compiler which source code to include or ignore when doing a build.

For example: if we have the following golang code:

// +build integration

package integration

import "testing"

func TestSomething(t *testing.T) {
	// Some test code
}

Then this code will only be compiled if we run the → Continue reading “Configuring VSCode to Use Build Tags in GoLang to Separate Integration and Unit Test Code”

VSCode Change Indent for File Explorer Tree

Posted on by rchapin

For me, I have a hard time distinguishing between the folders, sub-folders, and files in the file explorer of VSCode because the indent is not very pronounced.

In order to increase the indent go to File -Preferences -Settings. Search for “indent” and then click on Workbench in the left-hand side navigation pane of the settings window and scroll down to Workbench Tree: Indent and then enter the number of pixels for the tree indentation. I doubled it, going → Continue reading “VSCode Change Indent for File Explorer Tree”

Visual Studio Code Cheat Sheet under Linux

Posted on by rchapin

As I’m still learning vscode, I’m keeping track of a cheat sheet for shortcuts and other functionality for the IDE.

The following is under Linux, specifically Debian 10 with XFCE.

Keyboard Shortcuts

  • Edit a string in the entire file that matches exactly the string that you have highlighted. For example: you might have a comment, or a variable name, in a file that you want to find and change globally. Highlight the string and then type CTRL+Shift+L then type the

VSCode Keyboard Shortcut to Navigate Between Split Panes

Posted on by rchapin

In general, I cannot stand using a mouse. It hurts my hand and takes up a ton of time having to move my hand from the keyboard, to the mouse, move the mouse, click, and then move back to the keyboard.

I am a relatively new VSCode user and was pleased that it has a really good vim emulator. I almost always write code in a split screen so that I can either see two different files at the same → Continue reading “VSCode Keyboard Shortcut to Navigate Between Split Panes”

[SOLVED] Deleting remote git branch; By default, deleting the current branch is denied, because the next remote: ‘git clone’ won’t result in any file checked out, causing confusion

Posted on by rchapin

This is a common error encountered where you are renaming your default branch for the repository. If you have a repo hosted on GitHub or some other third-party service, there is likely some way in the GUI to change the default branch for a repo.

If you are hosting your own internal git repository you will need to SSH to that server and “checkout” a different branch from the one that you are trying to delete. In reality, the remote → Continue reading “[SOLVED] Deleting remote git branch; By default, deleting the current branch is denied, because the next remote: ‘git clone’ won’t result in any file checked out, causing confusion”

[SOLVED] Upgrading Apache Kafka 2.7 to Java 11 Changes authenticationID sent to ZooKeeper Enabling Only 1 Kafka Broker to r/w znodes

Posted on by rchapin

The title of this post is a bit of mouthful and requires a bit more explanation.

I am running a pure open-source version of Kafka (currently running 2.7) and am using SASL/GSSAPI connections between all of the brokers and ZooKeeper. Currently, the whole system, including ZooKeeper, is running Java 8 and it is long-overdue to be upgraded to Java 11.

Upgrading Kafka to Java 11 causes the server to send an incorrect authenticationID String to ZooKeeper which results in the → Continue reading “[SOLVED] Upgrading Apache Kafka 2.7 to Java 11 Changes authenticationID sent to ZooKeeper Enabling Only 1 Kafka Broker to r/w znodes”

Baseline Settings for a VirtualBox Instance for a GUI under Debian 10

Posted on by rchapin

The following is a list of the basic VirtualBox settings to start with when using a VM with a GUI. Make sure that you have also installed the Oracle VM VirtualBox Extension Pack that is compatible with your version of VirtualBox and that you have installed the Guest Additions in the VM itself.

  • System
    • Motherboard
      • 4+GB of RAM, or whatever you have available
    • Processor
      • 2+ CPU (if you have the available cores/threads)
  • Display
    • As much Video Memory as you can

message=class configured for SSLContext: sun.security.ssl.SSLContextImpl$TLSContext not a SSLContext When Mocking Static Methods in Class

Posted on by rchapin

When mocking static classes with Junit4, Mockito and PowerMock, you may see the following log messages after annotating your test class if the code that you are testing is making HTTP connections:

message=class configured for SSLContext: sun.security.ssl.SSLContextImpl$TLSContext not a SSLContext

Your annotations for the class (or method) typically include the following:

@RunWith(PowerMockRunner.class)
@PrepareForTest({ SomeClassYouWantToMock.class })

This may cause some confusion, especially if whatever other code that you may have ONLY uses HTTP. Add the following to your annotations to tell → Continue reading “message=class configured for SSLContext: sun.security.ssl.SSLContextImpl$TLSContext not a SSLContext When Mocking Static Methods in Class”
