Although USB to Ethernet adaptors are cheap and plentiful, Mac OS X drivers are not.
USB-to-Ethernet offers you USB to Ethernet Adaptor Drivers.
There are two basic catagories of USB-To-Ethernet adaptors:
- USB 1.1 devices that use a Pegasus driver.
- USB 2.0 devices that use a AX8817x driver (or its successor, the AX88772).
Each disk image includes an installer for Panther or Tiger, and a "src" folder containing the corresponding xCode projects.
Installation
Download and mount the appropriate driver disk image listed above, run the corresponding installer for Panther or Tiger, and then restart your system as suggested. The Installer will ask you to authenticate so it can place the corresponding driver in "/System/Library/Extensions/" with the correct file permisions to load as a kernel extension.
Next, plug-in your Ethernet adaptor with a live Ethernet cable attached. When you open the Network Preferences panel, it should inform you that a new port has appeared and ask if you want to enable it. Enable the new port and apply your network settings. Thats it.
Each driver is pre-configured to recognize a handfull of common devices. If your device does not appear to be recognized by the driver, you might have to add it to the Info.plist file, which is located inside the USBPegasusEthernet.kext or USBAx8817x.kext directory. You can use the System Profiler or USBProber tool to find the corresponding Product ID and Vendor ID.
To uninstall the driver, make sure any USB adaptors are disconnected, and then drag the corresponding driver in /System/Library/Extensions/ USBPegaususEthernet.kext or USBAx8817x.kext to the trash. You may need to authenticate that you have administrator privileges.
USB 1.1 Performance
The Pegasus chipset provides a USB 1.1 compatible implementation which could be a concern for some users. USB 1.1 runs at 1.5 Mbps (low speed) or 12 Mbps (full speed). For best performance, its important to isolate any low speed devices on a separate bus. Mice and keyboards often run at low speed.
Using the Link Rate tool in IPNetMonitorX, I measured the link rate to another device on my LAN as 6 Mbps. The built-in Ethernet on my 12" PBG4 reported 44 Mpbs. When I measured the link rate to the next hop router through my cable modem, it reported 1 mbps. It didnt make any difference whether I used Ethernet built-in or the USB-To-Ethernet adaptor. Finally, I downloaded a 2.2 MB file to compare the throughput using the Monitor tool.
Both downloads took 5 seconds, but Ethernet built-in reached a peak rate of 589 KBps versus 579 kBps. Repeating the experiment several times produced similar results. Ethernet built-in might be 1-2% faster, but performance was clearly limited by the speed of my cable modem (Your Mileage May Vary).
USB 2.0 Performance
The AX8817x chip set provides a USB 2.0 compatible implementation which runs at up to 480 Mbps (high speed), so it should be possible to keep up with 100 Mbps fast ethernet as long as there are no other slower devices on the same bus. To test this I copied a 64.8 MB music file to my PBG4 laptop connected through a LinkSys USB200M Ethernet Adaptor (en3) and compared this to the same file transfer using Built-in Ethernet (en0).
Both transfers reached 10 MBps (80-90 Mbps) and took about 10 seconds. I repeated the test in the other direction.
While the USB-To-Ethernet adaptor was slightly slower, at 80 Mbps there was little noticeable difference. Files moved quickly from one system to another via 100 Mbps fast Ethernet. Copying the same file using AirPort wireless took 50-90 seconds.
Stability
While other USB-To-Ethernet drivers are reported to be buggy, I havent encountered any stability problems to date. The adaptor turns off when the computer goes to sleep and comes back on when the computer awakes. It does not support "Wake On LAN" at this time.
Wrap Up
This USB-To-Ethernet Adaptor combination could be an attractive solution for a Mac Mini, or old iBook used as an Internet gateway or server. Im particularly fond of using old laptops as servers since they are compact, quiet, use little energy, and include their own battery backup.

Discordian Date 1.2 brings a new and useful widget which is a principle concerned with the nature of disorder vs. order. Among other things, it purposefully contradicts itself in a number of ways. One of its benefits is a very regular calendar: All years have the same number of weeks and a new year always starts on the beginning of a week. However, the Principia Discordia is somewhat vague over how leap days should be applied - therefor, the widget can display the current date aligned either to the Julian or the Gregorian calendar.

Requirements: Mac OS X 10.4 or later

Trojan Wrangler 1.0 is a simple to use, yet sophisticated utility which scans media files for the resources that Mac OS X uses to locate code. There's some concern that Trojan horse programs can be hidden in certain media files (MP3, AAC, GIF, JPEG). There are plenty of other ways to disguise programs as other sorts of files so unsuspecting users can be tricked into running them, but if this particular issue is a concern Trojan Wrangler will let you scan any downloaded media files for hidden code.

The Tunatic database is maintained by the Tunatic community itself through a program called Tunalyzer. Tunalyzer (when installed and enabled) scans your computer for music. When it finds a song that is not in Tunatics database yet, it analyzes it and sends its audio fingerprint and metadata (title, artist, etc.) to the Tunatic server. Thus, that song can later be identified by other Tunatic users.
The more users install and enable Tunalyzer, the more songs can be identified through Tunatic. You have the power to make Tunatic better! :^)
Where does Tunalyzer look for music?
Tunalyzer looks for music in the "Music" folder in your home folder. Tunalyzer looks for mp3 or AAC files with metadata (title, artist, etc.)
If your "Music" folder contains mp3 or AAC files with inaccurate metadata, please dont enable Tunalyzer.
How much CPU/bandwidth will Tunalyzer consume?
Tunatic works in the background, when no user activity (mouse motion, keystrokes) occurs. Thus, Tunatic doesnt interfere with your work. And since audio fingerprints are highly compressed, Tunatic consumes very little network bandwidth.
What about privacy?
We are concerned about privacy. None of your personal information is collected by our software (Tunatic and Tunalyzer) or transmitted by our software from your computers to ours. IP addresses may be recorded for security purposes.
Enhancements:
- Tunalyzer now logs its activity. Click "View Log..." to see the log of processed tracks.
- You can now choose the location where Tunalyzer will search for music files. Click the "Choose Search Path..." button.

Requirements:

• Mac OS X 10.4 or later.

jscl-meditor aims to provide a free and open source Java symbolic computing library with a mathematical editor front-end. There are several computer algebra systems available on the market, most of them developed in other languages, mainly C/C++ and Lisp.
But the benefits of using java in symbolic computation are great. Aside from being widely used and to comply with various standards, this language has two features of concern : readability and portability.

The symbolic capabilities are currently:
- polynomial system solving
- vectors and matrices
- factorization
- derivatives
- integrals (rational functions)
- boolean algebra
- simplification
- geometric algebra
- java code generation
- graphical rendering of math expressions
