Hi, I have a weird problem with RSync: On a NAS are about 1,2 TB data. When I plug in a harddisk and make a backup with RSync, "df -h" shows the backup disk filling up to nearly 1,2 TB. But after RSync has finished, there are only 3.7 GB on the backup disk. System: Linux nas 2.6.37-gentoo-r4 #1 SMP Tue May 3 19:54:31 CEST 2011 x86_64 Intel(R) Atom(TM) CPU 330 @ 1.60GHz GenuineIntel

Hello all, I am implementing some simple obfuscation transformations in LLVM. One of the obfuscations involves searching for particular constants, and "unrolling" them throughout a procedure using arithmetic. In effect, certain constants are broken up into smaller constants and recombined as needed using the appropriate operators. I perform this on intermediate LLVM instructions. After

Matt, The LLVMCore library provides constant folding automatically. So, when your obfuscated module is read in and the assembler re-creates your constants, the arithmetic is done automatically and the constants are folded. To see where this is done, see lib/VMCore/ConstantFold.cpp Reid. On Thu, 2007-12-13 at 02:22 -0600, Matt Fredrikson wrote: > Hello all, > > I am implementing some

Dear OpenSSH team, First of all thanks a lot for your good work on developing such a usable peace of software. Nice job. As you may know, we have some issues using OpenSSH in Iran. Recently the government did some packet filtering on some protocols, including SSH. We don't know what exactly they've done but it appears to be some routing rule that prevents SSH protocol to initiate a

HI, I am interested in whether LLVM bit-code is ready for a distribution format(stored in software distribution package); is it easy to revert LLVM IR to C/C++ source code like Java byte code? My understanding is that. 1. LLVM IR is more like assembly code, so it is not easy for reverse engineering. 2. If it is easy for reverse engineering, does it mean it is not suitable for distribution

Hi folks, I''m a newbie in the Ruby land, The Ruby language and RoR looks really great but I think in my situation there is a problem, we are an ISV that sells web application and we don''t want our clients see our source code, I searched the web but couldn''t find any way to compile and\or obfuscate ruby code (in web (RoR)), is there such tool available for the language?

The other thread brought to my attention that only the <email> syntax obfuscates mailto links. Plus, while the entity encoding technique probably fools some scrapers, I doubt it's all that effective. Even Gruber uses the Hivelogic Enkoder [1]. So, what are people using for obfuscation and are you using any scripting or automation (filter that takes a pass before or after Markdown) to

LLVM IR represents higher level than assembler code, it keeps some names and it is easier to revert the IR to source code than a binary format. The main task of LLVM IR is code generation. I don't think adding obfuscation has particular worth, those who need it can use tools and approaches specifically aimed at obfuscation. Even simple rename of identifiers in source code makes C/C++ file

Hi All, Is this possible to generate LLVM IR from any static/dynamic link library? I have some static and dynamic link library and I want to generate LLVM IR as I want to obfuscate these libraries. Is there any way to do the same. Please give me some pointers on this. Thanks, Deep -------------- next part -------------- An HTML attachment was scrubbed... URL:

I just made a rails application that I plan to sell and dsitribute. I want to distribute it without having to worry about someone stealing the code and selling their own version. How do I do this? Is there a ruby obfuscator or anything that can keep someone from seeing the code? Thanks for your help. -- Posted via http://www.ruby-forum.com/.

Based on this you are not using SIS, so I wonder if those are some old emails when you were using SIS? Can you provide an example corpus of such mail? You can use e.g. https://www.dovecot.org/tools/dbox-anonymize.pl https://www.dovecot.org/tools/maildir-obfuscate.pl https://www.dovecot.org/tools/mbox-anonymize.pl https://www.dovecot.org/tools/mdbox-obfuscate.pl to obfuscate the mail.

Well, I've just added another directory to not make the redirected folders a the root. And, Favorites and Documents do work. Goog suggestion to check the Windows event viewer.

I'd like to know if there is any known project doing obfucated code generation or software watermarking in LLVM. The [obfucation/software watermarking] in machine instruction level usually requires to insert dead code, constant "unfolding", computationally intensive "opaque predicate", redundant calculation, duplicated calculation, etc, which all make the program

Hi all, I'm working on usability and accessibility for a project that uses Markdown. When I tried out a screenreader on the automatic e-mail links, I noticed that there's nothing there semantically due to obfuscation. I think that obfuscation in this way is a neat feature, I hadn't heard about it before. This would be even better if there was a way to both obfuscate e-mail

=== 1. Camping on Rack === I''ve just finished rewriting Camping to use Rack in the "core". I got rid of (a little less) than 1kB in camping.rb and removed lots of un-necessary files (lib/server/*.rb, fastcgi.rb & mongrel.rb). bin/camping does now only provide WEBrick, Mongrel and console-support and should only be used in development. It uses Rack::ShowExceptions to catch
