Kill 'em All — DDoS Protection Total Annihilation! TONY MIU TECHNICAL DIRECTOR, BLOODSPEAR RESEARCH GROUP WAI-LENG LEE VP OF ENGINEERING, BLOODSPEAR RESEARCH GROUP With the advent of paid DDoS protection in the forms of CleanPipe, CDN / Cloud or whatnot, the sitting ducks have stood up and donned armors... or so they think! We're here to rip apart this false sense of security by dissecting each and every mitigation techniques you can ....
HTTP Time Bandit VAAGN TOUKHARIAN PRINCIPAL ENGINEER, QUALYS TIGRAN GEVORGYAN ENGINEERING MANAGER, QUALYS While web applications have become richer to provide a higher level user experience, they run increasingly large amounts of code on both the server and client sides. A few of the pages on the web server may be performance bottlenecks. Identifying those pages gives both application owners as well as potential attackers the chance t....
Pwn The Pwn Plug: Analyzing and Counter-Attacking Attacker-Implanted Devices WESLEY MCGREW RESEARCH ASSOCIATE, MISSISSIPPI STATE UNIVERSITY Malicious attackers and penetration testers alike are drawn to the ease and convenience of small, disguise-able attacker-controlled devices that can be implanted physically in a target organization. When such devices are discovered in an organization, that organization may wish to perform a forensic....
Transcending Cloud Limitations by Obtaining Inner Piece ZAK BLACHER With the abundance of cloud storage providers competing for your data, some have taken to offering services in addition to free storage. This presentation demonstrates the ability to gain unlimited cloud storage by abusing an overlooked feature of some of these services. Zak Blacher is currently pursuing a Masters of Mathematics in Computer Science, and expects to be..
Hacking Driverless Vehicles ZOZ CANNYTROPHIC DESIGN Are driverless vehicles ripe for the hacking? Autonomous and unmanned systems are already patrolling our skies and oceans and being tested on our streets and highways. All trends indicate these systems are at an inflection point that will show them rapidly becoming commonplace. It is therefore a salient time for a discussion of the capabilities and potential vulnerabilities of these sy....
Many web developers know about SSL, but it is very common to see it only partially deployed, or not deployed where it should be. This basic guide on when and how to deploy SSL will help you avoid the most common mistakes. via A basic guide to when and how to deploy HTTPS — Erik Romijn.
On seeing WarGames for the first time in the 1980s, I wondered which magazine it was. Later, after seeing it on TV and on VHS/DVD, the same question kept nagging at me. I believed that I would one day get to the bottom of this matter. I correctly assumed that the magazine was a real world magazine with a fake advertisement added to it. Through some effort and persistence I finally achieved my goal on 2013-02-24 at 5:30pm.

Octopress and S3 I’ve finally moved this site over to Octopress and S3. There is a lot of work to be done, the most pressing of which is fixing leftover broken images, implementing code highlighting, and fixing some theme stuff (like the navigation links), but other than that it’s going ok. The move overall was pretty hassle-free with no real problems. I ended up with the following setup:
Hi Edg3e, I hadn't looked into using Voiceover to activate app switching and so on - that's... interesting. It takes away one of the few things I preferred about the Surface, whilst adding some of its own new annoyances. Progress, I guess? I sympathize with the copy and paste - often I wanted to take some text from the console and put it into a bug ticket; I ended up writing a small script that uses our bug tracker's API to add a comment ....

A little over a year ago I wrote a post about using Beyond Compare on Mac via Wine. A native version is now in beta and open to everyone! If you haven't tried Beyond Compare, I suggest you do. If you have you already know how awesome it is. I've been testing the Alpha for many months now and thought I'd throw together some instructions for getting it going with git.

I think that turbolinks is great: it makes it easy to add AJAX PushState to your Rails Applications. The only problem with that is that we can’t use it any WEB application, because it’s a Ruby Gem. So I did some ugly-but-easy hacks and add it to this very site. I will describe the steps below.
This book was amazing, I was thinking that the amount of pages the book offers wouldn’t be able to tell a good story but this…
Figure 1: Sample screenshot editing my .vimrc Vim is an excellent text editor. I've used it for many years and like most vim users, have collected a fairly large collection of settings in my .vimrc and learned how to grok my vim usage effectively through a lot of trial and error. To that end, I've tried to assemble a useful overview of my experience with vim. Foreword: Why? Why would you want to even put in the effort to ....
From a certain version of the “jetty” package in Debian Linux, if the web application didn’t start up (servlet init() throws an Exception), this error wasn’t logged anywhere. The solution is to install the libjetty-extra package. sudo apt-get install libjetty-extra It took some amount of experimentation to find the solution. I don’t know why you’d ever want to not log errors; i.e. why the logging of errors is an “extra”.
Recently, Phil Robertson of the sensational cable TV program Duck Dynasty has drawn quite a bit of flack for his very Christian views kept largely hidden until now through A&E’s refusal to air his more candid statements. Setting personal opinions aside though and totally disregard the absurdity of crucifying Phil for his beliefs because today’s hyper-sensitive, disgustingly entitled society seeks to vilify everyone who challenges their nu..

When I joined college I was a pretty bad swimmer. During freshman year I took some beginner/intermediate swimming classes and learned proper swimming technique for stomach crawl, breaststroke and butterfly. The next year I saw this class called Master’s swimming, spoke to the coach and signed up for it. I was by far the weakest swimmer in the class. Everybody else had great stamina and technique. We would do series of 50 metres swimming f....
Well, One Game a Month is done! I’ve managed to complete 12 games for the year. My motivation by the end was lacking, so I took it kind of easy this month and made a very simple and quick game called Simon Says . Last month’s game, 9 to 5 , took much longer due to the number of art assets required. I’ll write a proper post about the challenge, how everything went, etc later.

I needed a script that checks: whether a cronjob ran at its determined date (that means it runs regularly) if the cronjob ran successfully It should also be monitor-able via Nagios . That means, it should provide a meaningful output for when something went wrong with the cronjob, e.g. “ CRITICAL : cronjob did not run!” Of course, someone already had the same requirements and built a Perl-script for it, which in turn can be used as ....

Introduction The first thing I did when I started programming in Go was begin porting my Windows utilities classes and service frameworks over to Linux. This is what I did when I moved from C++ to C#. Thank goodness, I soon learned about Iron.IO and the services they offered. Then it hit me, if I wanted true scalability, I needed to start building worker tasks that could be queued to run anywhere at any time. It was not about how many..
I wrote a couple months back about exploring FDWs. Its become quite clear to me, despite still having ample room for improvement, they’re not getting enough attention. Foreign data wrappers are perhaps better thought of as a foreign table, or even better yet as a view into some remote data source. They don’t take care of auto-updating or syncing data, thats all up to you, but it gives you a straight forward mapping to work with remote data ....

Talking about Node.js history, it’s talking a little bit about V8 history.

So lets begin talking about Node.js origins, the V8 javascript engine. V8 is an opensource project by Google and it is in the very core of Google Chro....
