lxsplit : split and join files

lxSplit is a simple tool for splitting files and joining the splitted files on unix-like platforms, such as Linux, FreeBSD, OpenBSD, etc.

lxSplit splits and merges files with the -s and -j flags respectively. Starting with version 0.2.1, lxSplit can handle large files (>= 4 GB) both when splitting and joining.

It can be installed from the ubuntu software centre.

Usage:
To split a big file into smaller pieces of 15 MB each, run the following command:
lxsplit -s hugefile.bin 15M
Output size can be given in (M)egabytes, (k)ilobytes and (b)ytes.

To merge (join) the already split pieces into the original big file, run this command:
 lxsplit -j smallfiles.bin.001
All resulting files (from either splitting or joining) will be placed in the current directory.

It has got 412 billion stored pages and you may look into older versions of any website or you can get link to any software/tool which used to be a website. All you have to do is, provide a link or part of a link to search. For example, to know how my website used to be in 2013, just type http://www.thechaithanya.com and you can see a calender with some of the dates highlighted, on which they had the snapshot of my website. You can even provide a part of link. For example, to get the link of older version of Android ADT, search using http://dl.google.com/android/adt/* You can find a set of links and...

Setting JVM Heap size at runtime

To set the JVM heap size, compile the program normally. For example, consider Runtime.java program. Compilation: javac Runtime.java Now, to set minimum heap size(let, 16 MB) required by JVM, run the program as follows : java -Xms16m Runtime  We can also restrict maximum size(let 512 MB) utilized by JVM: java -Xmx512m Runtime  Both these options can also be combined to specify upper and lower bounds of JVM heap size: java -Xms16m -Xmx512m Runtime Now you can run a program that requires huge computational space.
