CCFinderX, the new CCFinder

Finding code clones is far from trivial. For a nice explanation about the challenges of finding clones in source code, I suggest reading: "Comparison and evaluation of code clone detection techniques and tools: a qualitative approach". You can start by reading sections 2 and 6.

There are at least two tools with source code available under permissive free software licenses. Deckard and CCFinderX. CCFinderX is an evolution of CCFinder, made by the same author.

Deckard is easy to build and test, however CCFinder was not. For Linux users, I made a fork from gpoo/ccfinderx, and made some changes to simplify the build on Linux. The main change is to separate the core from the GUI. I have now two repositories:

https://github.com/petersenna/ccfinderx-core

and

https://github.com/petersenna/ccfinderx-gui

Both are clones from gpoo/ccfinderx, but I've spited things. At the moment the GUI do not work but you can build CCFinderX-core without wired OpenJDK dependencies. And it works producing textual output. My goal with this repositories is provide source code that can be compiled, packed, and distributed.

Sorry, but I do not understand the code either. Good luck!

Toshiba R830 and 16GB of RAM

Image
The datasheet of Toshiba R830-10P mentions that the maximum memory capacity is 8GB. See it  here . But Intel says that the i7-2620M supports up to 16GB of RAM. See it here . I have asked for help on Toshiba Forums. Nothing useful from there. See it here . I was curious as I have a very particular need for 16GB of RAM. Today I decided to give it a try. I bought two Patriot PSD38G13332S (8GB PC3 - 10600 1333MHz CL9 SoDimm) and installed it on the notebook. It just worked. So if you have the need for 16GB of RAM and a similar notebook from Toshiba, you can install 16GB of RAM.

Five steps to create Fedora chroot jail using yum

Pre-Notes: - This will work only if your Linux Distro is based on RPM and YUM. I have tested it on Fedora but it may also work on RHEL and Centos... It will NOT work on Ubuntu, Debian, Suse... - The operating system and its version will be the same inside and outside the chroot jail. - On the example, the chroot will be placed at: /chroot/devel - To install different version of Fedora or other RPM based distro, it will be necessary to manage yum package repositories outside the jail. The five steps: # 1 - Create the chroot directory $ sudo mkdir -p /chroot/devel/var/lib/rpm # 2 - Initiate rpm db on chroot $ sudo rpm --root /chroot/devel --initdb # 3 - download Fedora Release package. # If you do not want Fedora, download the correct *-release package and use it # on step 4. There are examples on the references. $ yumdownloader --destdir=/tmp fedora-release # 4 - Install downloaded Fedora release inside chroot $ sudo rpm --root /chroot/devel -ivh /tmp/fedora-release*r

How to recompile software with hardware optimization?

This may be useful for compiling local applications that you want to run faster. Try this on your computer: $ echo "" | gcc -march=native -v -E - 2>&1 | grep cc1 On my computer it has returned:  /usr/libexec/gcc/x86_64-redhat-linux/4.6.1/cc1 -E -quiet -v  - -march=corei7-avx -mcx16 -msahf -mno-movbe -maes -mpclmul -mpopcnt -mno-abm -mno-lwp -mno-fma -mno-fma4 -mno-xop -mno-bmi -mno-tbm -mavx -msse4.2 -msse4.1 --param l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=4096 -mtune=corei7-avx This command probes the local computer for optimization flags. To use it: $ CFLAGS=" [blue string from above] " ./configure You may consider adding the "-O3" flag. The -O3 flag enables levels 1, 2 and 3 of compile time optimization. There are more information about -O3 on gcc man page. For doing it, instead of previous line, use: $ CFLAGS="-O3  [blue string from above] " ./configure From:  http://blog.mybox.ro/2011/11/02
