 |

I have added a 10MB highly random file to http://www.metacompressor.com/uploads.aspx
as file13 :-) You can try your luck and submit a command line
compressor/decompressor as zip file at http://www.metacompressor.com/submit.aspx
to be tested live.
Code: LongNightsDebugging
Keep it clean, don>t spoil the fun.
It run at Windows 2008 server 64bit (support 32bit) at 1-4 CPU cores
4,0Ghz+ 45nm, 2GB DDR3-1600+. If you use more then one core and as
compiler Visual Studio enable then gcServer for quicker runtimes, see
http://msdn.microsoft.com/en-us/library/ms229357.aspx
Note: some compressors are not Vista/Win2008 User Account Control
(UAC) command line ready, like paq8o9 what give error: tmpfile:
Permission denied. |

Thanks, be aware file5 is 2GB not all compressors support this size.[/quote]

excellent security MODEL not necessarily implemented to full extent. I
am creating a language called JAM at present which should compile the
syntax of java with a slightly modified class library. I can not use
the C compilier I have as it is propriotary (for Amiga, Inc. SDK) and
well you could always fix my java classes of open squirt, it just
needs the bias element class writing correctly as per the pdf. and a
few modifiers in the carrier class to take into account the more
efficient underflow count block processing method.
ah well thats all folks...
jacko.
p.s. i still wonder why j2c is not built as p2c and f2c and etc...
p.p.s. why wernt the radio>s seperated more so as to lower the shot
noise corelation?? |

I checked this for paq8o10t.exe, after opening the input file and
creating the output file paq8o10t.exe try to create a file in the root
C:\t3no:
Operation: CreateFile
Path: C:\t3no
Result: ACCESS DENIED
Desired Access: Generic Read/Write, Delete
Disposition: Create
Options: Synchronous IO Non-Alert, Non-Directory File, Delete On Close
Attributes: N
Sharemode: Read, Write, Delete
AllocationSize: 0
Why not read the TEMP or TMP environment variable and use that path
for this temp file? |
