1388 - JavaScript | 2013-11-27

Sigflup calls in a "off the cuff" episode about JavaScript from the Hospital.

From Wikipedia, the free encyclopedia

JavaScript (JS) is an interpreted computer programming language. As part of web browsers, implementations allow client-side scripts to interact with the user, control the browser, communicate asynchronously, and alter the document content that is displayed. It has also become common in server-side programming, game development and the creation of desktop applications.
JavaScript is a prototype-based scripting language with dynamic typing and has first-class functions. Its syntax was influenced by C. JavaScript copies many names and naming conventions from Java, but the two languages are otherwise unrelated and have very different semantics. The key design principles within JavaScript are taken from the Self and Scheme programming languages. It is a multi-paradigm language, supporting object-oriented, imperative, and functional programming styles.
The application of JavaScript to uses outside of web pages—for example, in PDF documents, site-specific browsers, and desktop widgets—is also significant. Newer and faster JavaScript VMs and frameworks built upon them (notably Node.js) have also increased the popularity of JavaScript for server-side web applications.
JavaScript was formalized in the ECMAScript language standard and is primarily used as part of a web browser (client-side JavaScript). This enables programmatic access to computational objects within a host environment.

0917 - Uber Leet Hacker Force Radio 6 | 2012-02-06

In a welcome return to HPR, SigFIUP talks to us about two of her projects:


concr is an encryption framework for use to partially encrypt configuration files, or any file for that matter. concr is for use in UNIX systems and consist of two parts, libconcr and confcrypt. libconcr is an API for reading partially encrypted files and generating keys. confcrypt is a user-application for encrypting files using keyfile database or manually specified keys.

concr leverages the own-by-root aspect of programs in UNIX systems and stores it's decryption key inside of the application. Applications that use libconcr must be installed with execute-only permissions.

When an application is linked with and makes use of concr it, when run for the first time, will generate a copy of itself containing a private rsa-key and output a public rsa-key. confcrypt is a user program that encrypts messages to be decrypted by second runs of the application. concr provides an api similar to that of libc for reading in files thus making it transparent to the application developer what is and is not encrypted in those files.


yesplz is a screeenshot uploader command line utility written by sigFLUP that will take a screenshot, tag your photo, log into, post the picture to your photo album, and return an ascii bunny on success.

In order for it to work, you must have an account at but that is free and you can enter nothing but fake information into it.

Then simply run yesplz --help to see the possible tags and instructions for yesplz.
