In my last post, I wrote about four integration scenarios using databases: Reference data, Consolidated view, Subscription and Publishing. Of these, the Consolidated View scenario requires the most interaction between the server and the client roles. This post will examine how to make the pieces fit together. Consolidated view joins the data of multiple clients into a consolidated view. This makes you able to create administrative applicati..
In my last post on using the database for integration, I argued that the best metaphor for creating systems that are interconnected is that of One-Large Database. Carl-Henrik asked some very relevant questions about this, which I will interpret (for now) mainly as “how do you avoid drowning in complexity”. This post will address the issue of maintainability, especially when things grow to be large. The On Large Database metaphor is mostly u..
I got the following addition on my Dell XPS LED code from David Pritchard. The new version of the code has a “-touchpad” argument. Specify “-touchpad 1” to turn the XPS 2 touchpad light on, “-touchpad 0” to turn it off. Here is the updated source code and executable. The executable should work without Cygwin now. (Note to self: Use “-mno-cygwin” gcc option to strip out the dependency)
I started to get errors when using gmail. Gmail is normally very reliable. I would enter the URL in Firefox, the white background with “Loading…” top-left would appear, then a little later “This appears to be taking longer than normal” would appear, and that was it. It turned out, I only got the errors when using a T-Mobile UMTS card (in Austria). This has an option to “compress images” which is on by default. This means that JPEGs look..

Honking Cars in Egypt, especially Cairo honk all the time. Day and night. If we woke up at 4 am in the hotel room, there would be cars honking outside. The honk to wake up pedestrians or other cars, taxis honk to attract the attention of potential customers, and often, it seems like they honk just for the fun of it. Security There’s a ton of policemen in Cairo, easily recognizable by their white uniforms.
After a rather unsuccessful day, we decided to have a more aggressive program the last day in Cairo. We started out early with a subway trip to Coptic Cairo. It seems that very few tourists are using the subways, which is a pity because it is a pretty good system. If they only could have any information in English. We had to trust the ticket guy who said it was LE 2 for both of us.
We had a late start on Wednesday. We are going to take the train to Alexandria, and we want to make sure that we get the tickets, so we start with a trip to Ramsees railway station. I had expected the trains (which seem nice from the guidebook) to be much used by tourists, but as it turned out, all the information was in Arabic, with the platform numbers, and the word “platform” as the only thing in English.
In Cairo, we have noticed a recurring theme. Many places that are visited a lot by westerners are sectioned off from the rest of the city. When Egypt was a British colony, the colonialism was expressed by importing British culture into Egypt. With modern colonialism, a section of the western world is placed wholesale as a small colony inside the city. After a rather tiresome day, we didn’t feel like we had the energy to go egyptian style ag..

Abstract: This presentation looks at several scenarios of aggressive self defense. It applies the law to each of the participants in various schemes to the aggressor and to the defender. We see where simple self defense options could actually result in prosecution to the aggressor; prosecution of the defender; prosecution of both; or, be faulted for screwing up an investigation rendering a prosecution impossible. Many of the legal rationale....

Abou el-Sid is located in Zamalek along the Sharia 26th of July. The doorman for the hotel hailed a cab for us (and got a bit of baksheesh for that, I don’t know if that was right), and negotiated an overpriced fee. :-) The traffic is seeming more and more what people warn that Cairo traffic will be like. Previously, we’ve felt that despite the messiness of the picture, things have been managable.
Philip R. Zimmermann is the creator of Pretty Good Privacy. For that, he was the target of a three-year criminal investigation, because the government held that US export restrictions for cryptographic software were violated when PGP spread all around the world following its 1991 publication as freeware. Despite the lack of funding, the lack of any paid staff, the lack of a company to stand behind it, and despite government persecution, PGP..

Abstract: Birth, School, Work, Death. Imagine every web search you've ever done placed on a timeline of your life. Is there anything on that list you wouldn't want your mother (or employer) to know about? How about the aggregate web searches of your entire company? What if they fell into the hands of a competitor? Recent trends indicate that we can no longer rely on the privacy policies of individual web companies to keep this information ....
Abstract: In the first half of this session, Paul Simmonds will present on behalf of the Jericho Forum taking participants through the initial problem statement and what people need to go away and start implementing. Topics will include: 1. De-perimeterization - the business imperative 2. From protocols to accessing the web - the technical issues 3.

Abstract: Binary disassembling and manual analysis to find exploitable vulnerabilities is a cool topic. What's cooler? Saving yourself hours of time and brain rot by letting a program do the hard parts for you! In this talk, we will dissect a well-known exploitable vulnerability as well as an open source tool for automatically detecting that vulnerability. By the end of the talk, you will understand the basics of static code analysis, expl....
Abstract: The Church of Wifi (reformed) has been busy coming up with new and wonderful wireless shenanigans. At Shmoocon we sped up WPA cracking 3 fold, at Layerone we made it even faster, now we take it even further, to places and sizes not dared before: WPA2! When we aren't breaking WPA or cavorting with Evil Bastards, we are thinking about the future. With so many networking devices running embedded OSS software, they are almost whole ....

WarRocketing : Network Stumbling 50 sq. miles in <60 sec. Rick Hill, Senior Scientist, Tenacity Solutions, Inc. Abstract: Network "stumbling" has taken many forms since Marcus Milner first released Netstumbler in May 2001. Historically, stumbling aficionados preferred data collection method has been Wardriving. Almost everyone owns a car and it's easy to fire up your laptop and drive around. Of course, other methods exist, creative soul....
Abstract: Trusted computing is not inherently evil. It sounds scary, but it's true. While the public perception of trusted computing is that content providers will use trusted computing to enforce their digital rights and take away our civil liberties (whew! a mouthful), the reality is that there is a lot of good to be done by trusted computing. For more than thirty years, computer scientists have been trying to find ways to make trusted ....
Abstract: The proliferation of malware is a serious problem, which grows in sophistication and complexity every day, but with this growth, comes a price. The price that malware pays for advanced features and sophistication is increased vulnerability to attack. Malware is a system, just like an OS or application. Systems employ security mechanisms to defend themselves and also suffer from vulnerabilities which can be exploited. Malware is n....
Abstract: Smart phones are the new favorite target of many attackers. Also most current attacks are harmless, since these mostly rely on user mistake or lack of better knowledge. Current attacks are mostly based on logic errors rather then code inject and often are only found by accident. The talk will show some real attacks against smart phones and the kind of vulnerability analysis which lead to their discovery. Bio: Collin Mulliner is..
