(In case you're wondering, I also had to add a clone() to the set method, because otherwise the caller might call the set method, but keep the reference that it passed to it and modify it later.) Java offers no solution for this problem. What if, instead of a vector, it was an image? And what if it was accessed many times per second? This could quickly become impossibly slow. The second problem is that returning an entire copy might be SLOW. Since the user will have no way to tell if he's getting the actual position or a copy of it (unless he enters the original source or look in the documentation), he might try to modify the position that he got, and then be surprised that it doesn't work. There are two major problems with this: First, the previous code STILL COMPILES. In other words, you're now returning a full copy of the object. Private Vector3f position = new Vector3f() Since Java lacks this feature, you are forced to use annoying workarounds (such as keeping pools of objects) if performance becomes critical. Stack building makes this much faster, not to mention EASIER. In many situations, you will have to allocate many small temporary objects and then never use them again. Not only does it involve complex algorithms for determining WHERE to allocate the memory, but it also means that you're giving more work for the garbage collector when you're done with the object. For the rest of this post, I will write snippets in both C++ and in Java to illustrate the differences.Ĭreating objects on the heap is slow. Three, in particular, have always bothered me: stack building, operator overloading, and const-correctness. Since the software is free, it does not have commercial support meaning when a user encounters a problem, they will have to figure out how to solve the problem or ask for help in the community forum.This is a mostly off-topic rant that is being posted because I know that a good portion of our user base is composed of programmers.Įver since I started working with Java, a few months ago, there have been many things that I have felt SHOULD be there, but aren't. Some of the shortcomings of the software may include the complexity of the user interface may be a problem for new users. It is also compatible with Windows, Linux, and MacOS and there are tools to modify the text styles of the subtitles. Advanced features like task automation ease the user’s work in making the perfect subtitles. The software is also completely free and open- source meaning that anyone is open to contributing to it. The advantages of using Aegisub as a tool for creating and editing subtitles include it supports many subtitle file formats giving more flexibility to the users. The subtitle formats that are supported by this software are ssa, srt, sub, txt, ass, mkv, mks, and mka, and more which gives users more flexibility to be able to use any media platform to play the videos. Another feature of value in Aegisub is the automation of tasks like spell checking, correcting grammar errors, and the generation of subtitles from a script or speech recognition software. The software has a specialized tool that supports subtitles for karaoke and songs where users can match lyrics with audio and rhythm of the song. Also, it can support many subtitle tracks which help in translation and working on subtitles in different languages. There are options in the text editing tools that allow users to change the font, style, size and color of the subtitles so that they can match the standards of the video. It also contains powerful tools that aid in tasks like typesetting, timing, editing and translation of subtitles. With aegisub, the users of the software can arrange the subtitles according to the time of the audio or video playing. The live preview assists users to see how the subtitles will look in the video when they have been fitted together. Some of the features that this software has include a video player built in so that the user can view the video while working on the subtitles to match them well. The program was developed in 2008 by Niels Martin Hansen and it is supported in 17 languages. When a user needs to create new subtitles or edit those that are already on the web, aegisub is the best tool to use. Many people will view videos that have subtitles rather than videos that lack thus it is important to include them. Adding subtitles will help the video reach many language-speaking people in different countries. Subtitling videos are important because they help people who do not hear well to understand the content of the video when they read the subtitles. Aegisub is a software that allows people to create subtitles and they can also modify them.
