  Why Dynamic Programming Languages Are Slow

In a statically typed language, the compiler knows the data-type of a variable and how to represent that. In a dynamically-typed language, it has to keep flag describing the actual type of the value of the variable, and the program has to perform a data-dependent branch on that value each time it manipulates a variable.  It also has to look up all methods and operators on it. The knock-on effect of this on branching and data locality is lethal to general purpose runtime performance. T...

  Why I Quit My Job to Start a Tech Company

Back in November of 2006, before NY Mag and TimeOut put startups on the cover, before the “tech bubble”, before Twitter and Foursquare were popular, before working at a startup in NY was considered a reasonable thing to do, I was a private equity investor for a $1.6 billion fund called Quadrangle Group. It was just my third year out of college and I made a little over $250,000. For a Brazilian immigrant who spent most of his childhood kind of worried he would have to do physica...

  Applying Large Language Models (LLMs) to Solve Cybersecurity Questions

In this document, we will introduce some test, experiment and analysis conclusion about applying Large Language Models (LLMs) to solve cybersecurity questions. Introduction Large Language Models (LLMs) are increasingly used in education and research for tasks such as analyzing program code error logs, help summarize papers and improving reports. In this project, we aim to evaluate the effectiveness of LLMs in solving cybersecurity-related questions, such as Capture The Flag (CTF) challenges, ...

  Why we don’t hire .NET programmers

Skip my post and read this one instead.  It says the same thing, but less offensively.  (Or, rather, more offensively to Facebook and Google employees, less offensive to .NET developers, though the underlying message is the same.) Tuesday midnight edit: After >500 comments, >1000 tweets, and >1000 Facebook likes, I’m closing comments on this thread so we can all get back to work.  The very last comment takes the cake, however, and is a fitting close.  Th...

  Impact of AI on UI/UX design

The growth of computerization and Artificial Intelligence implanted into our regular daily existences in the course of recent years is only productive, we're no longer talk about fantasy since machines are going on at this very moment. This quick advancement has propelled a radically new age of designers to search for client-focused arrangements through the extent of these innovations. Along these lines, we need to investigate what this implies for UX plan in 2018 and what standards we should gr...

  The mystery of Duqu Framework solved

The Quest for Identification In my previous blogpost about the Duqu Framework, I described one of the biggest remaining mysteries about Duqu – the oddities of the C&C communications module which appears to have been written in a different language than the rest of the Duqu code. As technical experts, we found this question very interesting and puzzling and we wanted to share it with the community. The feedback we received exceeded our wildest expectations. We got more than 200...

  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...

  Go Lacks Ternary Operators. Here Are Some Equivalents

If you were like me, a pure Java developer before writing Go, you must be wondering why Go doesn’t support the ternary operator like return a > 1 ? 0 : 1. Most mainstream languages like C and Java are supportive of ternary operators; languages like Python and Ruby support the simplified if-else one-liner, such as a = 0 if a > 1. However, Go is not among them. And it is not only about adding operators but also a concept of coding in a more convenient way, such as the ?: expression can...

  Transparency in Cloud Services

37signals recently launched public “Uptime Reports” for their applications (announcement). The reaction on Hacker News was rather tepid, but I think it’s a positive development, and I applaud 37signals for stepping forward. Reliability of cloud applications is a real concern, and there’s not nearly enough hard data out there. Not all products are equally reliable; even within 37signals, the new reports show a 3:1 variation in downtime across apps. That said, ...

  Web Symbols typeface

There are those points in every interactive designer’s career when he becomes fed up with producing the same set of graphics all over again for every website he designs. It could be the social network icons, gallery arrows or any number of his «signature» butterflies for the footer of each of his projects. Similar for interactive developers that have to slice the same GIFs and PNGs each time art-director asks them to.U...
