New proposed frontpage for reactos.com
by Jason Filby 29 Mar '05

29 Mar '05

Hi all A new proposed frontpage for reactos.com can be found here: http://reactos.com/newsite/reactos_index.html None of the links go anywhere yet. ezPublish will be phased out and most of the content hosted in a wiki (editable only by people trusted in the project). The wiki/forums/blogs would require a bit of a face-lift so as to look similar. Comments? Cheers Jason

Will RC2 be == final actually RC2 --------- So this is what I wanted to send yesterday. However my smtp-provider didn't work as I would have liked to. Thus I'm doing the LABEL now. __now

Would it be possible to go ahead and port some of the Wine advapi32 SCM code? Its able to install and run services such as the Windows Installer so that might solve a few problems we are facing with the Msi service and CoLinux.

RE: [ros-dev] ping Alex regarding log2() for scheduler
by Waldo Alvarez Cañizares 29 Mar '05

Can't that one be transformed to do a Bit Scan Reverse? I guess there are alogorithms for it too. Try near the link I provided. Or try the Angner Fog's optimization manual. If that does not works you could try SuperOptimizer. Is a program that finds algorithms in assembler for some arch (x86 included of course) by means of trying instructions using bruteforce (you can use several computers if you want), usually can be converted back to a HLL. This function is little enought to let superoptimizer work. Find it, is open source software, a little complex and MACROfied piece of code but somehow modifiable to suit your needs.

call for an atapi tester
by Hartmut Birr 29 Mar '05

29 Mar '05

Hi, does anyone own a motherboard with an intel chipset and with an ICH5/6 io controller hub? I've modified atapi a little bit. Atapi may detect the second ide (SATA) controller of an ICH5/6. I'm interested on the debug output from atapi while booting. - Hartmut M:\Sandbox\ros_work\reactos>set SVN_EDITOR=notepad M:\Sandbox\ros_work\reactos>d:\programme\subversion\bin\svn.exe diff drivers\storage\atapi\atapi.c Index: drivers/storage/atapi/atapi.c =================================================================== --- drivers/storage/atapi/atapi.c (revision 14209) +++ drivers/storage/atapi/atapi.c (working copy) @@ -123,7 +123,15 @@ ULONG Dummy;

Changing syntax style of files to ms style...
by Gregor Anich 29 Mar '05

29 Mar '05

Hi! Sorry if I sound a little harsh, but I am upset by the fact that i don't understand what has driven someone to change the style of a file when adding one line of code from the old (whatever) style to ms style (where '{' and '}' are on the same line as the if/else keywords - that makes multiline if/else blocks unreadable to me, I esp. dislike it when the if-expression is also multiline - like if (some_very_long_expression_which_does && not_fit_onto_a_signle_line) { ... } ) I am not sure, but I think it was Alex. Would you please tell me why you changed the style of the file? I am pretty much used to the old style, esp. if i have been working on the file before it's strange for me to see the syntax changed in a way which i dislike as much as the ms style or whatever it is. :-/

Can you point me to time/date/subject you refer to. Just Wierd that i make one implention of taskmgr their where better than the previous then some just take some of the work modify it and credit themself.. i where planning of release the version today with network status and user tab also an vc++ comp. but can see it dont matter.. :-) > > To talk about something else i start a new projekt called CubeOs > > and i would like to know if their are any special copyrights in reactos..? > Just curious: what is the project about? Its an Reactos Clone did alot of work my self and with some developers not to make a competition but to make an alternativ with some of my ideas and visions it has allways been my dream... hope its okay with the reactos team.. By the way thx for your german translation its a littel useless now on reactos but will be very happy to use it on CubeOS Greetz Thomas

Wine has a good bit of that implemented using a pipe for communitcation but I assume on Windows its all LPC/RPC to support "net start servicename". Anyway if no one objects I will look at importing the hackish Wine code and see if I can make it work. Thanks Steven __________________________________ Do you Yahoo!? Yahoo!
