  What is Hystrix and How does Hystrix work

Background In distributed systems, there is one effect where the unavailability of one service or some services will lead to the service unavailability of the whole system, this is called service avalanche effect. A common way to prevent service avalanche is do manual service fallback, in fact Hystrix also provides another option beside this. Definition of Service Avalanche Effect Service avalanche effect is a kind of effect where the service provider fails to provide service which causes t...

  SQL Injection through HTTP Headers

During vulnerability assessment or penetration testing, identifying the input vectors of the target application is a primordial step. Sometimes, when dealing with Web application testing, verification routines related to SQL injection flaws discovery are restricted to the GET and POST variables as the unique inputs vectors ever. What about other HTTP header parameters? Aren’t they potential input vectors for SQL injection attacks? How can one test all these HTTP parameters and whic...

  How Computers Boot Up

The previous post described motherboards and the memory map in Intel computers to set the scene for the initial phases of boot. Booting is an involved, hacky, multi-stage affair – fun stuff. Here’s an outline of the process: An outline of the boot sequence Things start rolling when you press the power button on the computer (no! do tell!). Once the motherboard is powered up it initializes its own firmware – the chipset and other tidbits – and tries to ...

  PHP: a fractal of bad design

Preface I’m cranky. I complain about a lot of things. There’s a lot in the world of technology I don’t like, and that’s really to be expected—programming is a hilariously young discipline, and none of us have the slightest clue what we’re doing. Combine with Sturgeon’s Law, and I have a lifetime’s worth of stuff to gripe about. This is not the same. PHP is not merely awkward to use, or ill-suited for what I want, or suboptimal, or...

  The Mature Programmer

1. The Mature Programmer The mature programmer manages their own time and productivity well. The MP knows that maintenance is as much work as the initial writing and code always takes longer than you think. The MP knows that any changes to code can introduce bugs, no matter how seemingly trivial. The MP knows that premature optimization is foolish and dangerous. The MP knows that sexy coding like writing big complex systems from scratch is rarely the best way to go. The MP does not get...

  How big are PHP arrays (and values) really? (Hint: BIG!)

Upfront I want to thank Johannes and Tyrael for their help in finding some of the more hidden memory usage. In this post I want to investigate the memory usage of PHP arrays (and values in general) using the following script as an example, which creates 100000 unique integer array elements and measures the resulting memory usage: <?php $startMemory = memory_get_usage(); $array = range(1, 100000); echo memory_get_usage() - $startMemory, ' bytes'; How much would you expect it to ...

  What Can We Learn From Dennis Ritchie?

As we noted earlier this week, one of the founding fathers of UNIX and the creator of C, Dennis Ritchie, passed away last weekend. While I feel that many in computer science and related fields knew of Ritchie’s importance to the growth and development of, well, everything to do with computing, I think it’s valuable to look back at his accomplishments and place him high in the CS pantheon already populated by Lovelace, Turing, and (although this crowing will be controversial, at lea...

  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...
