Speed up Netbeans in Ubuntu Linux

Java Netbeans is a pretty decent editor for PHP code. I use Linux Ubuntu now for my primary desktop computer, so it’s quite convenient and easy to get running.

One issue is that in default configuration the program is a bit slow feeling.

Doing a quick search I found this page:

http://performance.netbeans.org/howto/jvmswitches/

Which describes a few command line parameters that might help the IDE function faster.

I’m currently running the command “/usr/bin/netbeans -J-Xverify:none -J-Xmx384m -Dsun.java2d.opengl=true”

Basically, it removes one unnecessary verification check, adds 256mb of RAM to the default RAM pool the program can use, and attempt to use OpenGL to render the IDE. I am currently using closed-source video card drivers, so your mileage could very with that last parameter.

You can modify your default system menu link by doing this:
Right-click on the “Applications” dropdown system menu. Select the “Edit Menus” list item.
Click the Programming menu and then the Netbeans X.X icon. There will be a Properties button where you can modify the command being called. Just add the parameters you would like to try out in there.

Overall I feel a noticeable improvement in scrolling, auto-completion pop-ups, and switching between tabbed documents with the limited bit of testing I’ve done so far.

ChatGPT is a new, and faster, way to do programming!

Currently ChatGPT is in a free “initial research preview” . One of its well known use cases at this point is generating software code. I’ve also just used it to write most of this article… Well, actually a future article about cleaning up SRT subtitle files of their metadata faster than I have been by hand with Notepad++ and its replace functionality. Update: I recorded a screencast of writing the SRT subtitle cleaner application loading and processing portion. I relied heavily on ChatGPT for code. It was a fun process! https://youtu.be/TkEW39OloUA ChatGPT, developed by OpenAI, is a powerful language model that can assist developers in a variety of tasks, including natural language processing and text generation. One such task that ChatGPT can help with is creating an SRT cleaner program. SRT, or SubRip Subtitle, files are commonly used to add subtitles to video files. However, these files can become cluttered with unnecessary information, such as timing lines or blank spaces. To clean...

Theme error in 2010s Android App after AppCompat Migration

I plan on releasing a lot of my old work as GPL open source, but most of it has aged to the point that it no longer functions, or if it does work it’s running in compatibility mode. Basically it’s no longer best practices. Not a good way to start off any new public GPL projects, in my opinion. The current project I’m working on is an Android app that calculates star trails meant to help photographers get or avoid that in their night time photos. For now I’m going to skip some of the import process because I didn’t document it exactly. It’s been mostly trial and error as I poke around Android Studio post import. The Android Studio import process… Removing Admob Google Play code before the project would run at all. After removing dependencies, it kind of worked, but when running it in the emulator it shows a pop-up message saying that the app was developed for an old version of Android. Going through the process of updating code to match current best practices… I had the IDE convert the ...

Printing to file in Linux WINE

I noticed that this post has been sitting as a draft since 2011. At this point I have no idea if it’s useful or what I was even doing, but I might as well make it public in case someone can find it helpful! So I’ve been trying to get one of those PDF print drivers working in WINE without success. I then came upon a process that might work. When printing you need to select the checkbox “Print to file” that creates a .prn file. Just Linux things... I was using a program that only has printing facilities, but I want to export around 100 pages of text and images. Once you have the .prn (postscript) file, you can do any number of things to it. In my case I want the postscript file to be converted to HTML. I am also considering PDF format because that has more conversion options to eventually get me to HTML or plain text. sudo apt-get install cups-pdf Or it looks like that package might have changed to this… sudo apt-get install printer-driver-cups-pdf Where PDFs would be generated in /home/...
