U111-M Q&A, Compatibility with Mac OS X? on EverythingHerePlus.com Store blog - Plus U111-M on OpenBSD and Linux updates!

The store blog from EverythingHerePlus.com answers questions regarding U111M compatibility with Mac OS X in Store EverythingHerePlus.com: U111-M Q&A, Compatibility with Mac OS X?. Of interest is the OpenBSD work around testing we did. U111M units with the most current firmware (1.05 above) work just fine with OpenBSD, with the exception of PCMCIA PC Card hot-swapping. As long as the card is inserted in the U111-M prior to connecting, the OpenBSD kernel recognizes it. In fact, there's no need to reboot between PCMCIA PC Card exchanges. Unplugging and plugging in the U111M on the USB bus is all that's necessary to recognize a new card.

Using OpenBSD, we were able to read, write, format, create binary images from, and write binary images to PCMCIA PC Card SRAM and ATA Flash. These capabilities, using just standard command line Unix utilities, are features once exclusively part of expensive, proprietary, Windows software packages. Now, using the U111-M with OpenBSD or Linux provides important low level features often needed with equipment from Honeywell, Canon, Epson, and others.

EverythingHerePlus.com will soon have detailed instructions for these operations.

U111-M USB to PC Card Read-Writer 1 Slot PCMCIA PC Card ATA Flash and SRAM Memory Cards

The U111-M is an external read-writer for PCMCIA PC Card SRAM, and ATA Flash memory cards. The U111-M works without additional software or drivers on supported operating systems, treating both SRAM and ATA Flash as standard removable USB mass storage devices. Used in concert with a Type II PC Card adapter, the U111M USB to PCMCIA Memory PC Card drive will work with a variety of consumer memory cards including CompactFlash and SD Cards. Used with desktop or notebooks computers, the U111-M USB to PC Card Read-Writer 1 Slot PCMCIA PC Card ATA Flash and SRAM makes copying files to and from PCMCIA PC Card SRAM and PCMCIA PC Card ATA Flash devices simple and straight forward without confusing software interfaces.

The U111-M comes with a USB 'Y' for use on rare systems with underpowered ports. Simply plug in the additional power only connection in order to provide necessary current. The U111M provides an inexpensive, hassle free solution to deploying legacy PCMCIA PC Card memory SRAM and ATA Flash cards on modern Linux and Windows computers with USB 1.1 or USB 2.0 ports.

FireWire 800 Hubs for New iMacs and Macs as easy as 3, 4, 5!

The recent transition to 9-pin FireWire 800 across Apple's product line has many people scrambling to find FireWire 800 hubs. Not to worry, EverythingHerePlus.com offers 3, 4, and 5 port FireWire 800 Repeater Hubs. Great for new Macs, iMacs, and other computing environments utilizing high performance FireWire 800 peripherals.

FireWire 800's sustained performance, coupled with other advantages like long cable runs, the ability to daisy chain, and more, make it one of the best and most versatile standards. With a theoretical maximum throughput of 800Mbps, FireWire 800—also known as IEEE 1394b, can typically deliver 80MBps (megabytes per second) performance when used with high end external hard drives like those by G|Tech.

FireWire is a true peer-to-peer technology, unlike the prosaic USB standard. Connectivity terminology for FireWire 800 Repeater Hubs is a little different than those that use star topologies exclusively. The count on a FireWire 800 Repeater Hub comprises the total available ports, since a host computer is considered another peer level device. In other words, plugging a computer into a five port FireWire 800 Repeater Hub leaves four available ports left.

These five, four, and three port FireWire 800 hubs are great for the new Mac Pro, MacBook Pro, iMac and other computers deploying FireWire 800. The 3 port FireWire 800 Repeater Hub edition is a highly portable plastic model, great for traveling. The 4 port and 5 port FireWire 800 Repeater Hub models are constructed from sturdy aluminum and are great for studio and industrial applications. All three FireWire 800 Repeater Hubs accept the optional (purchased separately) PS-12VDC-UB 12VDC 3A External Power Supply to power devices that run off bus power.

Using 6-pin to 9-pin cables or FireWire cable adapters allow FireWire 800 hubs to work with FireWire 400 device of both the 6-pin and 4-pin variety. In fact, since FireWire 800 is backward compatible, investing in a FireWire 800 Repeater Hub for use in mixed FireWire 800 and FireWire 400 environments is the higher performance, and more economical choice.

Paul Graham's "The Roots of Lisp"

Paul Graham's The Roots of Lisp, a cogent essay dealing with John McCarthy's astonishing 1960's paper which introduced the LISP language, and more importantly, the functional model of programing.

Graham stresses his essay is more important today than ever, given how more languages have moved (albeit in a piecemeal fashion) towards the LISP model. Working with seven primitive operators, the paper shows how the entire language is built. Most importantly, the paper shows the LISP trademark, how to write the language in itself.

An interesting aspect for Scheme programmers like myself is the discussion of dynamic versus lexical scoping.

Reading the paper reminds us of why functional languages, especially LISP based ones, aren't just the best for expressing algorithms, but are the most elegant models of programming since the are easily transcribed in mathematical notation.

I can't recommend The Roots of Lisp enough. The paper is available for free download on Paul Graham's site.
