obfuscation

I use Typescript command (tsc) to create a single Javascript file containing all plateform classes. tsc "./Main.ts" -out "./script/myProject_debug.js" --declarations Then, I want to obfuscate this file with Google Closure (compiler.jar) like this : java -jar ./compiler/compiler.jar --compilation_level ADVANCED_OPTIMIZATIONS --js "./script/myProject_debug.js" > "./script/myProject.js". But when I execute the resulting obfuscated/optimized code, I got this following error : Uncaught TypeError: Cannot read property 'prototype' of undefined Which matches the following non-obfuscated JS code

What should I know about code obfuscation in Delphi? Should I or shouldn't I do it? How it is done and is there any good tools (commercial/free) to automate it? Why would you need to? As a whole Delphi does not decompile back, unlike .net, so, while decompilation is always a bit of a risk, Ive never found a decompiler that actually did it to a useful way, lots of areas got left as assembler and so on. If people want to rework your work, they can, no matter what, obfuscation or not, heck, some coders write almost naturally obfuscated code (having worked with a few) My vote therefore, is

I have to extract values from a variable that may be None, with some defaults in mind. I first wrote this code: if self.maxTiles is None: maxX, maxY = 2, 2 else: maxX, maxY = self.maxTiles Then I realized I could shorten it to: maxX, maxY = self.maxTiles if self.maxTiles is not None else (2, 2) But then I realized this might be the most succinct and easily readable: maxX, maxY = self.maxTiles or (2, 2) Is the latter acceptable, or too hackish? About, specifically, self.maxTiles if self.maxTiles is not None else (2, 2) I've found that "double negatives" of the general form if not A: B else: C

I want to obfuscate a war file using proguard,how can i do so ? Please explain me the steps I'm puzzled by this question. As other Java obfuscators, Proguard obfuscates the compiled bytecode (.class files) by renaming every variable, method etc. it considers safe to rename. I suppose you know this and know how to use Proguard for class files since you specifically asked about it. If not, read the proguard manual. As for war files, you can extract the class files from war (or jar) by unzipping it. (yes, a war is a normal zip file). Then you can run them through Proguard and zip it up again. You

It appeared as an answer in a question I asked about code that is too clever . But it's too clever for me to tell whether it's simply a joke. If it's not, I'd be interested to know how it works, should anyone care to explain.

I've recently learnt that the company that will handle the installation of one of our core products have previously tried to reverse engineer suppliers' work in evil purposes. Due to this I want to learn more about how to protect our work and so far I have thought of the following: 1) Obviously to use an obfuscator. Question is which one. 2) Encrypt config files as much as possible (especially endpoint information). 3) Move as much of the logic as possible to the web service. 4) Use SSL for data transfers. The project is written in C#/WPF and connects to a set of web services hosted on a IIS 7
