Introduction to the Application of eBPF in Golang
Most of the time, when we develop software or even use software, we play within the safe boundaries of the operating system. We might not know how the network interface welcomes that IP packet, nor how the filesystem handles the inodes when we save a file. This boundary is called user space, which is where we write applications, libraries, and tools. But there's another world, kernel space, where the operating system's kernel resides and is responsible for managing system resources such as memor...

A Python Optimization Anecdote
Hi! I’m Pavel and I interned at Dropbox over the past summer. One of my biggest projects during this internship was optimizing Python for dynamic page generation on the website. By the end of the summer, I optimized many of dropbox.com’s pages to render 5 times faster. This came with a fair share of challenges though, which I’d like to write about today:The ProblemDropbox is a large website with lots of dynamically generated pages. The more pages that are dynamically generat...

Python Deserialization Attack Introduction: How to Build a Python Pickle Bomb
This article introduces an old and classic unsecured Python data serialization feature (the pickle library) and demonstrates how a red team attacker can exploit it to create a malicious binary or text data file that executes remote code or commands upon deserialization. The following attack flow diagram illustrates this process: We will follow 3 steps with the program code to show how Deserialization Attacks Work: [ Step1 ] Crafting Malicious Data: An attacker crafts a malicious payloa...

PHP Security
1. IntroductionWriting PHP applications is pretty easy. Most people grasp the syntax rather quickly and will within short time be able to produce a script that works using tutorials, references, books, and help forum forums like the one we have here at PHP Freaks. The problem is that most people forget one of the most important aspects that one must consider when writing PHP applications. Many beginners forget the security aspect of PHP. Generally, your users are nice people, they will...

A re-introduction to JavaScript
Introduction Why a re-introduction? Because JavaScript has a reasonable claim to being the world's most misunderstood programming language. While often derided as a toy, beneath its deceptive simplicity lie some powerful language features. 2005 saw the launch of a number of high-profile JavaScript applications, showing that deeper knowledge of this technology is an important skill for any web developer. It's useful to start with an idea of the language's history. JavaScript was created in 1...

True Scala complexity
Update 2: Sorry for the downtime. Leave it to the distributed systems guy to make his blog unavailable. Nginx saves the day.It’s always frustrating reading rants about Scala because they never articulate the actual complexities in the core language.Understandable—this post is intended fill that gap, and it wasn’t exactly easy to put together. But there’s been so much resistance to the very thought that the complexity exists at all, even from on up high, that I thou...

Cross Browser HTML5 Drag and Drop
HTML5 Drag and Drop has been talked about a lot lately, but it’s hard to find really useful information about implementing it across multiple browsers.Mozilla, Apple and Microsoft all have pages describing how to use it, but their examples seem to work only in their particular browser (Apple’s example doesn’t even work in their own! Updated, Jan. 11, 2009: Although I have not been able to get this example working on Safari 2.0.4 and 3....
