Hi all, I'm working on a new feature for JITWatch1 to produce a report of suggestions where methods could be optimised and one area I'm looking at is highlighting hot methods that were too big (by HotSpot's limits) to be inlined. I've started by looking at Collections.sort after I discovered that j.u.ComparableTimSort.mergeAt(int) was hot but too big for inlining (356 bytecodes vs 320). I tried splitting that method into 2 smaller methods and rebuilding rt.jar and measured a 2.4% increase in performance using jmh when sorting a 1 million entry List of Integer. The same boost could not be achieved by a quick tune of -XX:FreqInlineSize and -XX:MaxInlineSize. Have written up the experiment on my blog2 and would appreciate any feedback as to whether my experiment and measurements are valid (this is my first play with jmh) and whether there could be anything to be gained by refactoring core classes with HotSpot inlining in mind.
Perhaps the exercise is moot now that a lot of the core libraries are being rewritten to use streams and lambdas? Many thanks, Chris @chriswhocodes 1 2 Martijn Verburg 03:18.

There are a lot, but most could be filtered away (mac specific, GUI code, com.sun even perhaps, CORBA, etc.) Might be worth pursuing if we want to polish some peanuts for Java 12;-) Regards Heinz - Dr Heinz M.

I always wanted my system to talk to me. Here is one project where in I almost did that. This is a Java based project which reads your unread mails info of your Gmail. To those who don’t know, Gmail provides RSS Feed of your mails. It asks for username and password, then it will show simple XML file containing the information about unread mails. By default it displays unread mails in inbox. Civilization 2 multiplayer gold free download. You can also see the unread mails in specific labels like spam, trash.
To do that just append the label at the end of above url like this. The URL uses simple HTTP Authentication. So you can download the XML file using two ways: 1. By providing username and password in the URL itself like this: 2. By providing Username and password in the headers while requesting the URL. So, after downloading the XML, which is darn simple to parse, you can extract the unread mails info quite easily.
In this series of posts we will develop a Simple Java Application from scratch to extract the information from that XML file and pass it to a VB Script which spells your mails. That’s it for now, Do check my. Man is documentation viewer for Unix. It is like your local Unix wiki. It holds the documentation for almost all commands. Finding commands: man -k 'command description' If you want to find all the compilers that are installed in your system run man -k compiler View command documentation: man 'command' You can see man page for man itself with man man Traversing man pages: Keyboard shortcuts for traversing a man page is similar to that of VI. J - Scroll one line up k - Scroll one line down h - Move one character to the left l - Move one character to the right Ctrl + u - Scroll half screen up Ctrl + d - Scroll half screen down Ctrl + f - Scroll full screen down Ctrl + b - Scroll full screen up Searching in man pages: man supports powerful regular expressions to search for a string.
/PATTERN - Search for PATTERN after the cursor position?PATTERN - Search for PATTERN before the cursor position Exiting from man If you want to leave man page, just type q (no Return Key required) That’s it for now, in the next post we will see how to create files and directories in Unix environment,. In this series of posts, we will learn the basic (i mean to say, absolute basic) commands you have to know if you want to operate any Unix based systems (Solaris, Linux, Mac, etc.,) like a geek. General structure of Unix commands: cmd options arguments The square brackets indicate that options/arguments are optional. While some commands require more than one option/argument, others can work without any of them.
We can specify multiple options for a command. Each option starts with a delimiter - Most commands support eight short/long/both versions for options.

If there is a shorter version available, avoid using long versions, because it lets you use multiple options with a single - like this: cmd -abcd Where a, b, c and d are options to cmd ls command ls is a short form of list. It lists all the files and folders. Like many Unix commands, ls also accepts many parameters.
Basic form: ls OPTIONS DIRECTORY/FILE/NONE List Directory contents: ls #List current directory contents ls DIRECTORYNAME #List contents of DIRECTORYNAME List all files and folders: The above command lists all (well, almost) the files and folders inside the directory. If you want to see even hidden directories and files use: ls -a #List hidden directories/files as well Show detailed information: ls -l #Show more information about all entires (except hidden) ls -lh #Same as above except with file sizes now in human readable format Each line in the above output gives information about a particular file (you can see file name at the end of each line). This is one of my favorite tricks. If you are using Ubuntu (any other unix based systems will do), just navigate to the cache directory of the google chrome (google chrome is called chromium on ubuntu) and execute the following command. Vlc `file. sed -n 's/^ (.
).Flash Video./ 1/p'` You will be surprised to see the number of videos you have in your system (the command will take sometime to execute). Note: This trick doesn’t work if you clean your cache via browser itself or using applications like ccleaner.
Here are the paths for cache directories of chrome under windows and ubuntu. /.cache/chromium/Default/Cache/ - for Ubuntu%LocalAppData% Google Chrome user data default cache - for Windows 7 Understanding the above command Let’s break the above command and see what it actually does. Step:1 – Selecting all the flash videos in the folder The very first step in achieving our goal is to select all the Flash Video files in the cache folder. You might think it is straight forward just run the command ls.flv But that doesn’t work. Because the files inside the cache folder won’t have extensions.
So we have to find another way of selecting Flash Videos from a bunch of other files. There is a command called file which outputs the type information of the given file irrespective of its extension. Take a look at the following screenshots to get a clear understanding of what the command does. File command example Ok, now we need a way to select files based on the output given by file command.
We can use sed for this purpose. Just pipe the output from file into sed to extract file names that has the string “Flash Video” in its file descriptor. File. sed -n 's/^ (.
).Flash Video./ 1/p' if you can’t understand what are those strange symbols in the above command, make a search on google about regular expessions. Step:2 – Playing the selected files in vlc media player Using command substitution, we can pass the selected files list to vlc. Vlc `file. sed -n 's/^ (. ).Flash Video./ 1/p'` Command substitutions can be performed using Back Ticks or $.
That’s it.,.

Xerces2 is the next generation of high performance, fully compliant XML parsers in the Apache Xerces family. This new version of Xerces introduces the Xerces Native Interface (XNI), a complete framework for building parser components and configurations that is extremely modular and easy to program. The Apache Xerces2 parser is the reference implementation of XNI but other parser components, configurations, and parsers can be written using the Xerces Native Interface.
