Booting baby!

2008-12-19T00:09:00.000-08:00

Finally we know that our AOT is not creating soooo much garbage code :) At least we have a small bootable example binary, compiled using our AOT compiler. Long story short:

New website, Linkers, and much more

2008-12-04T17:34:00.001-08:00

So we finally moved from our old redmine system to a new website. We're now hosted at codeplex.com and www.mosa-project.org now redirects to www.codeplex.com/mosa

The main reasons were the instabilites we encountered with the home-server we used before.
But that's not the big news. The big news are that the compiler is finally getting more and more stable and reaching all the functionality we've planned for 0.1

The PE Linker grover worked on is working and I finally got the ELF32 Linker to produce valid ELF files.

Here some screens:

Invoking the compiler

Running objdump to check if the file is valid

Testing iCloud

2008-11-18T11:14:00.001-08:00

As I'm more than interested in OS development I _had_ to take a look at the iCloud Beta Program, and today I was confirmed to be part of the beta program *yeah*

So, to make it short, here some screenshots, and a screencast.

LongOperandTransformationStage completed

2008-11-12T12:14:00.001-08:00

A few minutes ago I implemented the last remaining missing method, ExpandURem, and it's finally working. So the LongOperandTransformationStage class is now completed and passing it's tests.

There're more and more issues that we're solving and I'm very optimistic that we'll be able to release the first milestone by the end of november or at least before christmas.

Toying around with VS 2010

2008-11-06T19:02:00.001-08:00

Ok, there's a new feature in VS 2010 called "Code Metrics".

Here the results:

Average Maintainabilty Index: 81.46
Average Depth of Inheritance: 3.1
Average Class Coupling: 96.47

I also tried to view the new class diagrams, but this feature still seems to be buggy as it crashed with a COM xception.

Visual Studio 2010 CTP & Mosa

2008-11-06T12:16:00.001-08:00

This night I've finally downloaded Visual Studio 2010 CTP Pre-Beta. As it comes as an VirtualPC Image configured with a pre-installed Windows Server 2008 it needed a little bit of tweaking to get it running in VMWare Fusion. But finally it's working.

Now I'll toy around a bit and test if Mosa runs on Visual Studio 2010. Report coming later...

Long time no see, long time no bug (until now)

2008-10-28T06:47:00.000-07:00

Yesterday we introduced new testcases containing constants to test our arithmetic operations we've implemented so far. Now we have a pretty big new buglist that we've to fix now :)

Well, better test and fix than ship and cry.

The tests revealed severe bugs, for example in our x86.LongOperandTransformationStage class. We're fixing those bugs at the time I'm writing these lines.

Stay tuned, we'll have knocked those bugs done as soon as we can and I'll tell you about it here.

2nd meeting finished

2008-10-18T14:44:00.000-07:00

The 2nd meeting just finished some minutes ago.
You can find the log here.
As assumed earlier, nothing special has been mentioned.

Meeting

2008-10-18T11:36:00.000-07:00

So, 1 hour left until our second meeting starts. I'm waiting to see what it'll bring up this time.
Though by looking at the topic list it's more a current status meeting than a meeting to decide MOSA's development in the future.
Well, we'll know more in about 3 hours when the meeting is over.

Until then: Stay tuned.

Moving to another testing environment

2008-10-13T20:04:00.000-07:00

As XP screwed up itself again I decided to remove it and install Vista in the VM instead.
So now grover and I will be able to compare MOSA's behaviour on XP and Vista.
Shouldn't make any difference at all, since we're not relying on the system underneath (apart from having to use Visual Studio for development).

Furthermore I'll now be able to use Pex (unfortunately there's no version for XP availabe) to generate some more random testcases for MOSA.

Merchandising

2008-10-13T04:25:00.000-07:00

As I've been posting some few news about MOSA on my private blog, I want to use this blog here also to present the first MOSA Merchandise article! Have a look and be amazed ;)

Rasterizer on its way

2008-10-13T02:55:00.001-07:00

As I had some free time yesterday evening I dived a bit into Pictor's rasterizer and worked on it. It's far from being finished, but the main algorithm is implemented and only smaller things have to be done to finish at least the rasterizer.

Crush'em baby!

2008-10-12T19:33:00.000-07:00

Just ran the last update to see how the testcases are doing. And they're doing just fine! In the last few hours we crushed the bugs really hard and put them at a significant loss in the big code battlefield and decimated their army from 48 failed testcases down to 15. We won't give them one minute to rest. We'll go out there, hunt 'em, pursue 'em, annihilate 'em!
Seems that the great victory of 0.1 is within spitting distance!

Welcoming a new member on the Development Team

2008-10-12T15:38:00.001-07:00

I want to hereby welcome our new member on the team. He's been helping a lot by creating issues and helping with minor bugfixes, so we decided to take him in and hand over the mosacl sub-project to him to let him make his first steps.
He's still young, but we have high expectations in him to become a good developer and team member.
So let me say: Welcome Boddlnagg!

Pictor added to Redmine

2008-10-12T15:28:00.000-07:00

We've finally added our Pictor library to the project's Redmine system.
Find out about it here. To cite Pictor's description:

Pictor is a vector graphics API to give operating systems a direct possibility of creating and displaying vector graphics. Pictor is capable of creating artifact free, anti-aliased and resolution independent images.

Pictor still has a long way to go and I doubt it'll be included in the 0.1 release as it isn't even near being stable or already functional. Furthermore, I just lack the time to concentrate on Pictor as we're all busy to remove the last bugs and add the last testcases to get 0.1 done. In addition there's a seminar work I have to prepare and write. So please don't expect much progress on Pictor in the next few weeks. I think somewhere between 0.2 and 0.3 I'll have the time I need to work on Pictor. So far only basic parts like the rendering buffer are working. So I expect it to be included in a release for the first time somewhere between 0.4 and 0.7

Approaching Release 0.1

2008-10-12T15:04:00.000-07:00

We've been quite busy in the last few weeks developing on MOSA and now we're not so far away from our first official release (0.1). There's only a small number of testcases left that need to be fixed and some minor features to implement.
So I expect 0.1 to be released end of november, or to put it another way: release ~ O(11/30/2008).

I hope that our first release won't reveal any crashing parts, as we've been testing it thoroughly (nearly 3000 testcases up until now).

So stay tuned and I hope you'll have fun with our first release!

This blog's purpose

2008-10-12T14:55:00.001-07:00

I've created this blog to seperate it from my personal blog at rootnode.de where I mostly blog about private things and otherr development stuff. I'll use this place here to blog about the development on MOSA (http://www.mosa-project.org) only.
