Apple Hints at 'Big' Event at MWSF:
Apple's web site front page today has a big bold comment on Macworld SF (Jan 7-11th) saying "This one is big - Even by our standards". Everyone is expecting new iMacs with LCD display, "G5" (7460 at least) tower systems with DDR memory, possibly a new Cinema display and perhaps even new Apple software. There have also been hints of a new "revolutionary device" to be announced. Only time will tell, but this could be the best Expo in years I think.

OS X PPP Authentication Credentials Disclosure Vulnerability:
Matthew Culmore sent a link to a Security Focus alert page on this issue. The page is dated Dec. 29th, but notes "Mac OS 10.0" as vulnerable but has no version listed in the "not vulnerable" field.
The Discussions page notes:

    " An issue has been reported in Mac OS X which could disclose the authentication information for a PPP connection.

    If a user has established a PPP connection, executing a ps command will not only display the information about current processes running, but will disclose the PPP username and password for Internet Connect.

    Their solutions page notes

    Currently the SecurityFocus staff are not aware of any vendor-supplied patches for this issue. If you feel we are in error or are aware of more recent information, please mail us at: vuldb@securityfocus.com "

A Note about G4 CPU Temperature Variations from Chip to Chip:
Last Friday's news page had some comments on reader reports of CPU temperatures from G4 Cubes (dual and single G4 CPUs). I've commented many times in the past that the temperatures reported with software utilities with G4 CPUs is not literally accurate (and the feature has been removed from rev 2.1 and later 7450s for instance) but thought they would be useful for relative comparisons. What I did not realize was that one potential reason for the wide range of reported temperatures could be variations from even the same model/revision of the CPU. Engineer Tim Seufert wrote that he's seen a 28 degrees C variation between the two G4 CPUs in his DP tower. (I know OS 9 doesn't balance the load well on both CPUs so one will run hotter than the other - but that's a huge difference.) Tim wrote:

    "BTW, about those dual processor Cubes... I don't think you'll find anything of worth by comparing temperatures, because the 7400 temp. sensor has a lot of variation from one processor to the next. For example, in my dual 500 tower the two CPUs are about 28 degrees C apart (as reported by a utility called ThermoGraph which supports multiple CPUs). They are both in good contact with the heatsink so that's pretty much impossible -- it's just that from one sample to the next you can get very different offsets from true temperature. (The G3 usually had a consistent offset for each CPU version, so you could apply a known correction.)
    Tim Seufert "

(Note: I forgot to mention the Thermograph page has this note on temperature accuracy:

    " "Note: Motorola documents the relative accuracy of the temperature measurements from the processor to be 12*C (21.6*F). Your measurements may vary." "

(The above may refer to G3 CPUs but just a FYI.)
On my Dual G4/500 Cube (2.9 rev 7400 G4s) in OS 9 I saw an appx 15C max difference using ThermoGraph in the two CPUs when running the Altivec Fractal Carbon demo, which uses both CPUs. OS X supports SMP at the core so it may better distribute the load on both CPUs, but Thermograph is not OS X compatible. I have not yet tested ThermoInDock (an OS X compatible temperature utility) to see what it reports with this dual G4 modified Cube. (The author's site is not accessable lately to see if it supports dual CPUs.)
I wonder how XLR8 handles this in their Dual G4 upgrades; their software reports/monitors both CPUs for overtemperature conditions. I can't beleive they would sample/test CPUs to match them in pairs.

To those that have written to ask - as soon as I can I will post my photos taken during the install/mods for the Duet in my Cube. With all the other work here and the holidays, I have not had time to write up the article and edit/trim the photos down to web page size. I used the Sonnet heatsink adapter, but I really don't like the fact it stresses the CPU card despite some mods I made to try to reduce the card bowing. Until I can make a better adapter plate however, that is what I am running. So far I've not seen any problems, but I wonder if this stress could cause circuit board de-lamination in long-term use. (Perhaps not.)

There are two previous articles on Dual G4 CPU modules in Cubes linked on the Systems page, Cube section for readers that missed the past links here.

More on PB G4 Gigabit Ethernet Low Memory Bandwidth:
In a follow-up to past comments on the PB G4 first models (7410 CPUs) having higher memory bandwidth than the later Gigabit Ethernet models (550/667 7451 CPUs) which one reader reported making a significant difference in Logic audio tests (see the update to this prev. article), Tim Chung wrote that a Japanese site has noted better memory bandwidth/apps performance after waking from sleep in OS 9.
To try and verify this personally, I tested a PB G4/667 here using CineBench2000, GaugePro and Throughput 1.5 and see no real difference in performance before or after waking from sleep. (I have the 4.2.9 firmware update applied, but other than some variation in the shading test in Cinebench from run/run - clean boot scores vs after waking from sleep show no real difference on this system. And scores are not really improved over those I noted in the previous article run before the 4.2.9 firmware update. Tim commented on a rev 11 Uni-N, but the PB G4/667 here has rev 17, as does the 2001 iBooks. PB G4/400 and PB G4/500s had rev 8 from what I've seen. The later revs had much higher Firewire port benchmark scores for instance.)

Despite the fact I do not see any gains after waking from sleep in tests so far with this PB G4/667 - if any readers see a gain in any test after waking from sleep with any model of Powerbook G4, let me know the details. [Note: Do not run OS 9 benchmarks in OS X classic mode - boot into OS 9 for these tests. It may not affect all benchmarks but I've seen ATTO's benchmark report 200+MB/sec rates for instance when run on Firewire drives in OS X classic, clearly inaccurate since Firewire has a 50MB/sec max interface spec and no single drive can deliver near those rates. OS X's cache I suspect is the reason for these inflated scores. Also repeat the tests several times if you can as I've seen more than what I consider normal variation in the shading scores of Cinebench from run to run, even after a clean reboot.)
For those that don't read the past reviews/articles here that link these benchmarks, you can download Cinebench 2000 here (set display mode to 1024x768, millions colors) and Throughput 1.5 is available here.

OS X iTunes Support File for LG GCE-8160B IDE CDRW:
" Mike, I'm a frequent visitor to your site. I am writing as I have purchased a LG GCE-8160B from Best Buy today. It appears it should burn properly from Disc Burner and Toast, but I was disappointed to find iTunes didn't recognize it.

I used HexEdit to look at the LGCDR.device-plugin file in OS X, but was unable to simply replace the model number in the file. Apparently for some reason the vendor for this drive is listed in System Profiler as HL-DT-ST. I then tried modifying one of the vendors with the same number of characters as HD-DT-ST. I ended up using Matshita, because it had a drive that had the same number of characters as "CD-RW GCE-8160B" and appeared from the functions underneath the vendor listings in HexEdit to support the same commands or function calls to the drive.

The modified file appears to work properly from iTunes. I have attached the file that should be dropped in /System/Library/PrivateFrameworks/DiscRecording.framework/Versions/A/DevicePlugins directory.
Itunes should burn fine with this file, although it only burned at 8X on my 16X burner (but that could have been the media, all I have are older CDRs from a spindle I had).
Clint "

I'll be adding his modified file download to the FAQ's CDROM/CDR section in the next 24 hours.
