Several things I've been meaning to post but haven't gotten around to it.

For starters we finally have our dog, he's a 4 year old adopted greyhound and his name is Seamus.

The breed's supposed to make exceptional pets and he's doing great so far. Remarkably calm and well behaved, almost never barks, completely leash trained and batting 100% on house training so far too. Still haven't had much luck getting him assimilated with the cats, he's prone to try to get too close to them, they hiss, he barks, they freak out. One's pretty unphased by him but the other is still terrified.

Up and running with Fedora 9 on both my work system and my desktop. preupgrade failed on both, first due to this bug, and the second system failed with an unable to find stage2.img message (iirc), haven't debugged this one yet. In both cases I resorted to a trusty (completely unsupported and probably dangerous) live yum upgrade. Working great on both systems post upgrade, stuck with the nouveau driver for now but it's behaving nicely with just an occasional switch to the console and back to alleviate this slight performance problem. I'm actually strongly considering replacing my desktop system as it's about 3 years old now, ridiculously loud, and refuses to suspend/hibernate which I'd like to use every night. Have my eye on Dell Inspiron 530 so far but suggestions would be appreciated. I read that it's pretty quiet, and within the price I'd like to spend to get a quad core system with a integrated Intel graphics (really sick of dealing with binary graphics drivers).

Rounder 0.0.1 is pretty much ready, like packaged up and ready to roll pending just a little bit of testing. It should have been released several weeks ago but I've been distracted because...

It's been a *HUGE* month for PS3 owners. Gran Turismo 5 Prologue, Grand Theft Auto 4, a new Warhawk expansion pack, there's just too much to find the time for. GT5p is visually stunning but I didn't find as addictive as I thought I would, just not enough content to keep me going and the online play really sucks. (chaotic, rude drivers, and no way to play with friends yet, just random matchups) Once GTA4 hit I've left it aside for now but will be returning sometime soon. GTA4 on the other hand is just stunning, easily the greatest game I've ever played. It looks fantastic but most importantly the whole city just feels alive. I could wander the streets in this game for hours on end, really enjoying it and the break from fast paced online gaming. Had some good times just screwing around in free roam with friends in the multi-player mode as well, but spending most of my time enjoying the single player experience.

I've caved and joined another cursed social networking site. You can find me as dgood on twitter.

I guess that's it.

I rewrote most of the GTK table code earlier in the week (have I mentioned how much I love Glade 3?) to now look *almost* like something that could actually resemble a poker table. Should now seat 10 players instead of the previous 4. Dozens of general gameplay commits to keep things running smooth, it's actually quite playable at the moment, we ran through several hands in a network game a couple nights ago and it seemed to be working fine, although it's a little disorienting when you're used to the sounds in actual online poker clients.

Between bowes and Kenny we've got a curses UI moving along, as well as a replacement hand evaluator that's not quite finished but when it is, will relieve the dependency we have on the non-Python pokereval code. Another friend is reportedly hacking on support for various graphical cards which will be an awesome addition.

"sudo python setup.py install" should now get you an installed and playable version of rounder-server, rounder, and rounder-txt (not yet completed).

Account creation is stalled due to some missing functionality in Twisted for anonymous logins when using perspective broker. Fix is coming out in Twisted 8, not yet in Fedora so I'm waiting for that to appear before I apply the patch to start us down the path. Once it's in logins will be anonymous, your avatar received then will only allow you to do certain things, among them create yourself an account, and of course login. This and chat (which will be super easy) are the only two things on my mind grapes that need to be done for a 0.0.1.

More info available on the project page for those interested.

After two days of obsessive coding Rounder is now in a playable state.

If you'd like to try it out:

1. Manually install the dependencies listed on the rounder project page.
2. git-clone http://anongit.dangerouslyinc.com/rounder
3. Spawn a server by running the rounder-server script in the top level of the source. Will be listening on port 35100 and can accept outside connections provided your firewall allows them through. Four $1/2 limit hold'em tables will be automatically created.
4. Run the client with the rounder script. (again top level)
5. Login as player0 (or player1 - player9) / password. Each login can only login once, although if someone closes their client that login should be freed up again.
6. Double click a table and claim a seat
7. Repeat with another client and username, or have a friend connect remotely.
8. A player at the table must hit the Deal button to kick off a new hand.
9. Act as prompted throughout the hand and repeat when the hand ends.

Should be able to play for a good long while. Things may start going wonky as you near 0 funds, most likely if you have to post a blind that puts you all-in.

Meanwhile Kenny & jbowes have kicked off a curses text client that's shaping up nicely (see rounder.ui.curses package), my wife's going to take a shot at Gimping up a table graphic for use in the background, and I've started writing up an architecture document to walk through the high level layout, layers, and some of the decisions made for anyone looking to get involved.

Getting really close to a point where we could do a 0.0.1 release. Some important things that still need taking care of:

• Distutils installation. (setup.py)
• Account creation. (accept requests from clients but only create the accounts in memory)

Moving into our house in about a week and a half so probably won't release until after that, but wheels are in motion. Until then feel free to checkout and tinker!

Big milestone in rounder development tonight. Brace yourselves for what's likely the most unattractive poker interface ever created:

This is two clients connected to a server, viewing the same table, with the first network events being dispatched and rendered. (player joined table and player left table) It's not a hard scenario to replicate if you have the source checked out and the dependencies installed, just fire up rounder-server, then run the rounder executable right in the top level directory as many times as you like. The server is configured to accept about 10 logins of player0/password, player1/password, etc.

Things have been moving along drastically faster lately, I've been finding about an hour a night to hack on it as opposed to the previous average of few hours a month. Meanwhile Kenny has jumped into the fray with a patch I consider quite impressive. Following my previous development update post bitching about the logic involved with handling all-ins, he started reading code and composed a much simpler and more logical way to handle this core engine logic and implemented the whole thing.

Tonight's milestone, while quite unimpressive visually, indicates that there's a LOT of plumbing in place. Seeing those little events fly back and forth was extremely fulfilling. Getting a hand to play through is now a matter of hooking up a minimal amount of code to fire off a poker hand, and continuing to add client support for incoming events from the server. (most of these are implemented and being sent out server side, although I'm sure there'll be a few to come down the line)

Still a pile of work to be done before a 1.0 but we're getting there. All the project info you desire is available here.

Rounder (my attempt to build an open source poker client/server/community started last March) development continues at a slow and not so steady pace. I've basically been averaging two (short) coding sessions a month since October thanks to work and my stupid (i.e. awesome) PS3. Going to try to bump that up to a couple times a week and so far so good since overcoming a bit of an unpleasant hurdle I've been screwing around with for literally months. (handling all-in calls/raises)

Basic architecture overview, a core poker engine (objects like players, tables, games, and limits), and a networking layer consisting of a server objects (creates and organizes engine objects) and a client object (bad name as this exists on the server and dispatches events and action prompts to connected clients). The client side program isn't really written yet, everything is currently driven through unit tests.

Status right now, engine is quite functional but even after months of hammering on edge cases and writing any test I could think of to make the thing break (then fixing it), I'm absolutely certain there's still problems in there. Coding poker logic has turned out to be a bit of a challenge, just so many deviations and one off situations, and I've had a lot of trouble coming up with ways to keep the code clean and logical. It's well compartmentalized and objects should have pretty well defined responsibilities, but there's still a lot of if/else cruft in them.

Now that I'm relatively happy with how things behave when you get down to all-in calls and raises, I returned to defining the missing events sent out to all a tables observers whenever something happens. This is pretty far along and most events are now defined, soon it'll be time to write the client to actually listen for them.

Unit tests remain a thing of beauty, no disk/network access compromises (Ran 87 tests in 2.435s) and great effort has been made to keep the code *extremely* testable.

I'm concerned about the decision to use Twisted for the networking layer. It seems awesome for Python but I have this nagging feeling that sooner or later, I'll want to write clients in something other than Python.

Roadmap:

1. Finish off event notifications.
2. Return to edge case testing for a few more things.
3. Write account creation glue.
4. Complete server code to spawn a single table. (i.e. someone creates a server, friends can connect by IP and play)
5. Write a really ugly and simple GTK client to actually be playable.
6. Implement database layer. (sqlalchemy, may have to be bumped up in priority)
7. Complete server code to manage creation of tables/games.

So still a long way to go. For anyone interested in jumping into the pool the project is written in Python and stored in Git. You can browse source at this location and clone with git-clone http://anongit.dangerouslyinc.com/rounder.
