Thread Pools

Thread pools on the JVM should usually be divided into the following three categories:

1. CPU-bound
2. Blocking IO
3. Non-blocking IO polling

Each of these categories has a different optimal configuration and usage pattern.

• stage 1: You believe you can make Go do object oriented programming. You want to do this by using clever struct embedding.
• stage 2: You believe goroutines will solve all of your problems. You want to use goroutines for anything and everything that you can, who cares if the code becomes a bit more complicated
• stage 3: You believe that instead of object oriented programming, interfaces will solve all of your problems. You want to define everything in terms of interfaces
• stage 4: You believe channels will solve all of your problems. You want to do everything from synchronization, returning values, and flow control using channels.
• stage 5: You now believe Go is not as powerful as people claim it to be. You feel like you're stripped of all of the nice tools and constructs that other languages provide.
• stage 6: You realize that stages 1~5 were all just your imagination. You just didn't want to accept the Go way. Everything starts to make sense.
• stage 7: You are now at peace

Quick Tips for Fast Code on the JVM

I was talking to a coworker recently about general techniques that almost always form the core of any effort to write very fast, down-to-the-metal hot path code on the JVM, and they pointed out that there really isn't a particularly good place to go for this information. It occurred to me that, really, I had more or less picked up all of it by word of mouth and experience, and there just aren't any good reference sources on the topic. So… here's my word of mouth.

This is by no means a comprehensive gist. It's also important to understand that the techniques that I outline in here are not 100% absolute either. Performance on the JVM is an incredibly complicated subject, and while there are rules that almost always hold true, the "almost" remains very salient. Also, for many or even most applications, there will be other techniques that I'm not mentioning which will have a greater impact. JMH, Java Flight Recorder, and a good profiler are your very best friend! Mea

Batch convert svg|pdf|eps|emf|wmf|ai|ps|cdr to eps|pdf|png|jpg|tiff|svg|ps|emf|wmf

Batch converter for Windows using Inkscape with the command line
InkscapeBatchConvert is an easy to use solution to quickly convert all files of a folder to another type without the need to open Inkscape. The program uses Windows Batch scripting and will only work on Windows.
Tested with Inkscape 1.0.x - 1.3.x ✅ (The last version that supports Inkscape 0.9.x can be found here)

Usage

1. Download _InkscapeBatchConvert.bat
2. Put it in the folder where you have files you wish to convert (will also scan on all subfolders for files of input type).
3. Then double click the file to start it.
