Presented 9/12/2009 at jQuery Conf 2009.
Like any good Javascript framework would, jQuery includes Ajax functionality into its core. In particular, though, jQuery has some interesting ways it approaches event handling with Ajax responses. We’re going to dive into this Ajax event mechanism, and see what fun we can have with extending it.
This talk will first review the various Ajax events and some common ways they are used. Then, we’ll investigate jQuery source code and see how each is accomplished. Armed with this knowledge, we’ll talk about some scenarios where you might want to extend these events with extra functionality, or even add your own custom Ajax events.
To move from the theoretical into the concrete, we will discuss two jQuery Ajax plugins I released, mpAjax and flXHRproxy, and look at how each needed in its own way to hook into the Ajax event mechanism and extend it.

Here are the key steps to convert a color image to a binary image in LabVIEW:
1. Read in the color image using the Read PNG or Read JPEG VI. This will return an image structure.
2. Use the Color To Gray VI to convert the color image to grayscale. This removes the color information and leaves only the luminance.
3. Apply a threshold to convert the grayscale image to binary. Use the Threshold VI and choose an appropriate threshold value (usually 128 for 8-bit images).
4. The output of the Threshold VI will be a binary image, where pixels above the threshold are white (255) and pixels below are black (0).
5. You can now process the binary

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Webinar Recording: https://www.panagenda.com/webinars/hcl-notes-and-domino-license-cost-reduction-in-the-world-of-dlau/
The introduction of DLAU and the CCB & CCX licensing model caused quite a stir in the HCL community. As a Notes and Domino customer, you may have faced challenges with unexpected user counts and license costs. You probably have questions on how this new licensing approach works and how to benefit from it. Most importantly, you likely have budget constraints and want to save money where possible. Don’t worry, we can help with all of this!
We’ll show you how to fix common misconfigurations that cause higher-than-expected user counts, and how to identify accounts which you can deactivate to save money. There are also frequent patterns that can cause unnecessary cost, like using a person document instead of a mail-in for shared mailboxes. We’ll provide examples and solutions for those as well. And naturally we’ll explain the new licensing model.
Join HCL Ambassador Marc Thomas in this webinar with a special guest appearance from Franz Walder. It will give you the tools and know-how to stay on top of what is going on with Domino licensing. You will be able lower your cost through an optimized configuration and keep it low going forward.
These topics will be covered
- Reducing license cost by finding and fixing misconfigurations and superfluous accounts
- How do CCB and CCX licenses really work?
- Understanding the DLAU tool and how to best utilize it
- Tips for common problem areas, like team mailboxes, functional/test users, etc
- Practical examples and best practices to implement right away
