• What's the best way to learn image processing?

  - by rdasxy

  I'm a senior in college that hasn't done much image processing before (except for some basic image compression on smartphones). I'm starting a research project on machine learning next semester that would require some biomedical image processing. What's the best way to get up to speed with the basics of image processing in about two months? Or is this impractical? It's my impression that once I'm good with the basics learning more from other resources would be easier.

• Unpacking a ZTE ZXV10 H108L router firmware

  - by v3ng3ful

  I binwalked a firmware of a ZTE ZXV10 H108L, and got some encouraging results of uImage uboot, and LZMA compression, as well as a Squashfs 3.0 LZMA compressed filesystem. 256 0x100 uImage header, header size: 64 bytes, header CRC: 0xE70BCBB9, created: Thu Nov 10 04:54:54 2011, image size: 804172 bytes, Data Address: 0x80002000, Entry Point: 0x80266000, data CRC: 0x6EFE90F1, OS: Linux, CPU: MIPS, image type: OS Kernel Image, compression type: lzma, image name: MIPS Linux-2.6.20 320 0x140 LZMA compressed data, properties: 0x5D, dictionary size: 8388608 bytes, uncompressed size: 2637958 bytes 851968 0xD0000 Squashfs filesystem, big endian, lzma signature, version 3.0, size: 2543403 bytes, 632 inodes, blocksize: 65536 bytes, created: Thu Nov 10 04:56:12 2011 Now what I did is, to test several portions of the file (320byte-end, 851968byte-end, and many more) using dd, and trying with certain tools to uncompress/unpack the filesystem of the firmware. After some digging I found out the best tool to do this is the firmware_mod_kit, that understands a squashfs-lzma v3 filesystem. Although I ended up really frustrated as unsquashfs-lzma v3 reported a cold "zlib::uncompress failed, unknown error -3". Do you have any ideas? Could it be that, the firmware is corrupted on purpose to discourage attempts like this? Router file Thanks

• Apache log rotation: logrotate vs rotatelogs vs chronolog

  - by Enrico

  I have been researching log rotation for my server which hosts ~5 fairly high traffic sites. From what I can tell, my options are to use logrotate or to use piped logging with either rotatelogs or chronolog. logrotate requires a restart of apache and both SIGHUP and SIGUSR1 restarts are less than ideal on high traffic sites, because either you drop a bunch of connections or you need to delay compressing the old log until all child processes have died naturally. Also, downtime can be quite significant if compression is enabled. Would using logrotate - without compression and with graceful restart - and compressing old logs after the fact be the best way to minimize downtime? chronolog and rotatelogs sound promising, but are not well documented. I couldn't find examples of using either in combination with vhost specific logs. The chronolog website says, "when the expanded filename changes, the current file is closed and a new one opened". Is this globally? Or is that per AccessLog, CustomLog or ErrorLog directive? Is there a significant difference between chronolog and rotatelogs?
