Here’s a story about a command-line app named speed-test that gives you network speed information from the command line.
Multiple sources, including AppleInsider.com, are reporting that Walmart plans to deploy 100,000 Mac computers to save on employee PC costs. From that article: “IBM noted that PC users drive twice the number of support calls compared to Mac users, and that PC support tickets require desk side support by IT personnel five times as often. The company's own analysis showed that each Mac deployed saves the company $270 in support costs compared to a Windows PC.”
I was going to write a little application to let me annotate my MacOS screen during presentations, but the Ink2Go product looks like it does exactly what I was thinking. As I’m creating a video presentation, such as when showing how to write some Scala or Android code, I want to be able to draw on the screen, such as writing text, arrows, circles, and boxes to highlight parts of the screen. Ink2Go looks like what I want.
I wrote earlier about how to use the
javapackager command to create a macOS application bundle from a Java application, so I won’t repeat all of that information here. Instead, in this article I just want to show how to display an image that’s stored in the Contents/Resources/Java directory of a Mac/Java application bundle.
If you’re interested in packaging Java applications on macOS, this is a good `javapackager` video on YouTube.
This is a good guide for things to be aware of when creating Mac/macOS applications using Java. It mostly includes a lot of information about the com.apple.eawt.AppEvent library/classes.
As a note to self, this apple.com Maintaining Your Signing Identities and Certificates page contains information on signing identities, certificates, provisioning profiles, developer accounts, developer id certficates, the keychain access app, exporting certificates, and more.
I recently learned how to use the Java javapackager command to build a macOS application bundle — i.e., a regular macOS application — from a Java application. In this tutorial I’ll show how to create a Mac application bundle from a simple Java class, in this case a Java Swing class.
As I learned recently, the Mac/Java AppBundler tool is a little out of date these days, but you can still use it with Java 8 and MacOS 10.12 to build Mac/Java applications. One problem you can run into is getting this ugly Info.plist error:
If you’re using the Oracle AppBundler to build a Mac/MacOS application bundle from a Java application and run into this error when running Ant:
NoSuchFileException: <directory path here> Info.plist
I have found that the problem is that I have not set and exported
JAVA_HOME. To set and export
JAVA_HOME on MacOS 10.12, I use this command in the shell script I use to build my Mac/Java app:
