Wow, a long period of time without a diary entry. )-: Lots of things have happened. Most notably my girlfriend and I got engaged! (-:

Much PhD work happened, too. A lot less Linux NTFS work happened unfortunately. I have certain doubts as to whether much Linux NTFS work will happen before I finish my PhD next summer but we will see...

I hope to be able to do some API cleanups to the NTFS library and to make a formal release as the last one was ages ago and we now have two new utilities longing to make public appearances (ntfsundelete and ntfsresize).

Another month over. Today we celebrate a big milestone in the development of the new NTFS driver. We now have working file data overwrite via mmap(2) working! And it even worked first time... (-8

My fingers are itching to get the write(2) based overwrite code done and dusted, too, so I can make a formal release to LKML and the world at large. Hopefully it will all have happened by the next time I remember to write a diary entry. (-;

It has been a long time since the last entry! How time flies...

Too many things have happened to list, Linux wise, libntfs has made very good progress, API freeze hopefully will be possible in the near future. The ntfs driver has made a lot of progress, too, to the extent that there are only two items on the ToDo list (NFS exporting and i_size overflow investigation) left before I begin to attack the long awaited write support.

Today we had our summer here in Cambridge, UK! Sunny and nice and warm. (-: Most likely it will start raining again tomorrow... It's been a particularly wet and unpleasant summer this year. At least I managed to spend a week in Scotland and a week in France where I enjoyed much nicer weather. (-:

Let's when I next remember to write a diary entry...

Almost a month without an entry... Oh well, better late than never. (-:

Released an update to the NTFS Linux kernel driver today. Nothing major. Just wanted to push it out in celebration that I finally have a booting 2.5 kernel again.

Have been hacking away on the ntfs library from the linux-ntfs package on Sourceforge. Dumped about a quarter of the code and started again, now going for a proper API which should hopefully not need to change once I am done hammering it out. Most of the code is modified or rewritten now, lots of code ported from the new ntfs driver, and I improved it on the way so it needs porting back into the driver now. (-8 Time has come for adding more features to the library but that is a slower process.

Not much else happening, much PhD work, also am sick for second week now but getting better slowly... )-: Oh well, gives me more time to sit at home, sip hot beverages and chat on irc. (-:

I should try and update this diary more frequently I guess. Perhaps next time... (-;

Finished the new NTFS Linux kernel driver (read-only)! Posted it and got some excellent feedback so far. Speedwise it definitely is a significant improvement. I am happy! (-8

Went to Richard M. Stallman's lecture on software patents this afternoon. Brilliant talk. RMS certainly is a very good speaker. And I fully agree with him, too. Software patents are evil full stop!

Had a feature request for mkntfs - to add ability to disable content indexing. Did that and while at it added ability to enable compression, too. After some small cleanups released Linux-NTFS 1.6.0.

Went on holiday to Austria for two weeks and enjoyed some great skiing in St. Anton am Arlberg. Had all kinds of bad weather ranging from two days with sun shine over rain, hail, snow, blizzards, and some real full blown snow storms. Fun, fun. (-:

Managed to sneak in some ntfs tng development into a few of the evenings so the driver is moving along nicely. Now have the options from the previous driver all supported but giving messages about them being deprecated and generally loads of code cleanups and enhancements. Noticed a few subtleties which require quite a bit of a rewrite of my readpage methods. Oh well, better now than after having gone into the kernel... That delays the driver quite a bit more than anticipated, so it won't be being submitted for kernel inclusion yet.

Been very busy with PhD work. First chapter is finished (results wise) and exciting results for the next one appeared which is fanfabulous. (-8

Ntfs tng is now feature complete read-only. It now reads all ntfs volumes from all windows versions (nt4/2k/xp) I threw at it and produces identical output as the old ntfs driver. - Some code cleanup left to do, some small odds and sods to implement /cleanup, bring up to speed with the latest 2.5.x offering and it's ready for the masses. The only thing then remaining is the fact that ntfs tng requires gcc-2.96 or later compiler which some people are not happy with, so I will probably have to play some dirty tricks to fix this temporarily. (Will revert them out once the kernel officially requires gcc 2.96 or later.)

Am leaving for a fortnight of internet deprived skiing holiday so no entries for a while! (-:

More fun with ntfs tng. Many cleanups, like the $ signs in identifiers are all gone now (now should compile on all architectures as long as they use gcc-2.96+), debug output is improved and can be switched on/off via sysctl/proc interface. Cleaned up mft bitmap handling and enabled loading of the complete run list. The mft data is already done which means we now should be coping with any possible mft a user will ever throw at us. (-: As it is all working nicely now I tagged a 0.0.6 release as the next set of changes is going to be enabling of full attribute list / multiple attribute extents support which may destabilize things.

Went to a charity quiz-night. Didn't win but had a lot of fun nevertheless. (-:

Had a play with encrypted ntfs directories and the ntfs 3.x extended system files. Adapted ntfs tng to cope with both and found a buglet in the process. Now all is happy.

Had a look at the compile warnings report for linux-ntfs 1.5.1 for powerpc. It seems powerpc use char == unsigned char which was breaking some signed char comparisons. Fixed that. Now need a powerpc person to test. (-;

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.

Keep up with the latest Advogato features by reading the Advogato status blog.

If you're a C programmer with some spare time, take a look at the mod_virgule project page and help us with one of the tasks on the ToDo list!
