I've been working on getting WPA encryption to work on Haiku. While I haven't been able to invest as much time as I hoped for before, I made a bit of progress that at least justifies a small status update.
The first part of WPA related work has actually happened while I was working on the network stack for Haiku Inc., as it was not possible to inject packets into the network - while you could easily monitor all incoming packets, there was no mechanism to send packets for arbitrary protocols. I've extended the AF_LINK protocol to be able to deliver that mechanism.
In an attempt to move on and get on to just the Haiku API, here are the final three lessons on C++. Lesson 3 introduces C++ file streams, formatting and printing using C++ streams, and lightly touches on exceptions. Lesson 4 takes a break from actual coding and spends time on a critical development tool: source control – what it is, how it is used, and why it is used. Lesson 5 ties together all of the C++ concepts covered in this series with a project. I hope you enjoy them.
Lesson #2 in my new series of development tutorials continues with a fast and furious course through the rest of the Standard Template Library with some of the Standard C++ library thrown in for spice. We learn about associative STL containers like map and set and examine the C++ string class.
Programming with Haiku, Lesson 2
On behalf of the Haiku Support Association (HSA), we'd like to invite you to our 23rd BeGeistert meeting on the weekend of 23./24. of October 2010. It will be held as usual in the nice conference rooms of the youth hostel in Düsseldorf, Germany.
BeGeistert is an excellent opportunity to mingle with and learn from other users and developers from all over Europe (and beyond: this year we're happy to be joined by Rene Gollent, flying over from the US, and Christof Lutteroth and Clemens Zeidler from New Zealand!). Hear about other people's projects or present your own, meet many of Haiku's core developers and discuss the future of Haiku. Or present your favorite KDL and see if our gurus can successfully debug it...
Google Summer of Code 2010 is now over. It was a wonderful experience, and I learned a lot about Haiku’s internals, about file system development, and about myself. I successfully completed my proposal to a point an initial version of the Ext3 file system is available to the Haiku kernel for testing. There are some things that remain to be completed, like sparse files, proper revoke support, multi-transaction truncation and some more thorough testing, but overall, it was successful.
This weekend was my second year at the Ohio LinuxFest at the Greater Columbus Convention Center in downtown Columbus, OH. I arrived at the convention center at about 7:15am. Unlike last year, there was hardly anyone there outside of the OLF staff doing checkin and a few vendors. Joe Prostko was already there, having stayed at a hotel nearby the night before. It was good to see him again. We started talked for a bit and then started getting the table set up. I made sure that we had enough supplies for the table and each of us had brought a demo machine. Joe brought an MSI Wind netbook which was running a nightly build and I brought my Dell Latitude D620 running an almost-stock Alpha 2. Both machines proved to be valuable for demoing different aspects of Haiku that day. Soon enough we started seeing some traffic.
Since I started publishing my Learning to Program with Haiku lesson series back in January, I have, on many occasions, seen comments asking for lessons aimed at current codemonkeys who want to break into development for Haiku. Here begins a new series of programming lessons aimed at people who already have a basic grasp on C++: Programming with Haiku.
The direction of the series is pretty straightforward. First, we’ll be spending some time (i.e. the first unit) delving into some less-commonly-used features of C++ which show up in Haiku from time to time. This is partly to bring up to speed those who are picking up the series after finishing the first one, but also to examine ways that features like containers from the Standard Template Library can be effectively used in combination with the Haiku API. There’s even a quick primer on source control thrown in for good measure – something which any developer should at least understand, if not use religiously. Following the first unit we will dig into the API. Depending on how things work out, there may or may not also be a crash course on GUI programming in there before diving into the kits themselves. Some of the lessons will deal directly with getting to know a particular kit. Others will examine important topics or the “Haiku way” of getting a task done. They should provide a good working knowledge of Haiku development methods that can easily be expanded into more advanced usage.
It was a fine, sunny morning in Brisbane, Australia: home of the Third Annual Haiku Down Under Virtual Conference for Haiku Users and Developers. Virtual in the respect that the event was streamed live over the Internet via the uStream service. We accept (and regret) that this service requires Flash, so you can’t use Haiku to view this event, you must use another OS like Windows, Mac or Linux.
This year, HDU (short for Haiku Down Under; not slang for How Dare yoU) were able to book a conference venue at The University of Queensland with projector, white board and limited seating where myself, Sikosis was joined by BeMark and Mojodale.
The coding period of the Google Summer of Code is now over since this Monday,
and it's time to give to the Haiku Community a debrief of what has been done on
my initial project, what has been modified, and what remains to do.
The fundamental parts of the journal code are finished. Although they still need more testing, and they can change as more of the Ext3 code is written, they are ready for supporting the first steps in write support for ext2 and ext3 volumes. This blog post explains the code, and how it is organized to handle ext2 and ext3 volumes.
