  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...

  Learn How to Write iOS Apps

My friend contacted me on twitter and asked for advice on different sources on how to learn iOS apps. Since this paragraph will already exceed 140 characters, I'm posting here, instead. (Obviously, reading this blog regularly is a great way to pick up some iOS development tricks) To get started, some people buy a book or find some good online tutorials. I tried both approaches, and the online tutorials were definitely better. I found Stanford's class on iPhone Development, available for free...

  If Multitasking Is Impossible, Why Are Some People So Good at It?

"Multitasking means screwing up several things at once," somebody once said, wrongly. In fact, we don't do many things at once, ever. We do many things in quick succession. And some of us are very good at it.Nagy-Bagoly Arpad/ShutterstockEverybody multitasks. We have conversations while driving. We answer email while browsing the Web. It's hard to imagine living any other way. What would be the alternative, removing the seats from your car to ensure you only drive alone? Block every website not ...

  Could coding be the next mass profession?

Like farming was in the 17th century, factory work during the industrial revolution, construction during the Great Depression, and manufacturing after World War II. Better, because writing code is a creative act which can be done with or without a traditional (antiquated?) office-based job, and can create enormous personal and economic value. Most young people start in jobs that don’t have much of a future. Most don’t get higher education – only a third get a...

  Lessons from the Trenches

I believe that making a game is part art and part science, so it's no wonder that managing a game project is also part art and part science. Clearly if it was all science then the industry would get a collective F for not having made any significant progress over the last decade - all one has to do is just glance at the published postmortems to see that the same patterns are repeated over and over.A game has to be fun, engaging, grab users in the first two minutes and also keep their a...

  Rebirth of Microsoft?

Only from the point of view of design and products, Microsoft may seem like an ongoing decline of the old giant: IE browser market share continues to drop, PC market continues to shrink where Windows depends on and tablet PC market gets rapid expansion, Windows Mobile, Windows phone perform not so well, even CEO Steve Ballmer is often ridiculed and accused. All these seem to indicate that Microsoft's golden era is over. But on the other hand, while its net profit for the past two years has ...

  Test-Driven Development? Give me a break...

Update: At the bottom of this post, I've linked to two large and quite different discussions of this post, both of which are worth reading... Update 2: If the contents of this post make you angry, okay. It was written somewhat brashly. But, if the title alone makes you angry, and you decide this is an article about "Why Testing Code Sucks" without having read it, you've missed the point. Or I explained it badly :-)Some things programmers say can be massive red flags. When I h...

  Deep Dive into Spin Locks in Golang

In concurrent programming, a Mutex is a commonly used synchronization mechanism to protect critical resources and prevent data races. However, in certain specific scenarios, especially when the lock-holding time is short and the number of threads is limited, a more lightweight lock known as a Spin Lock can provide higher performance. What is a Spin Lock A Spin Lock is a form of busy-wait lock. When a thread attempts to acquire a lock held by another thread, it continuously checks the lock's stat...

  For Google CEO Larry Page, a Difficult Premiere Role

When Google Inc. co-founder Larry Page announced that he would take over as chief executive earlier this year, he promised that he would shake up the Internet search giant to speed up decision making. Instead, much of the shaking up has happened to the new CEO.Challenges have piled up for Mr. Page since he assumed his post in April. They include a broad U.S. antitrust probe of the company's practices; the settlement of a long-running criminal investigation into Google's adver...
