Get Sun Certified for the Java1.4 platform! Now that I've got it, I can recommend it (yes, this is where I've been hiding out for the past few months). I highly recommend this book from Amazon.com to help you study for the Sun Certified Programmer's exam for Java 1.4 (310-035). The book comes with a CD-ROM that includes a PDF version of the book and several simulated exams that will prepare you for official version available at your local Prometric Testing Center. If you already have your java certification, be sure to check out SunEd's other certification programs.
Remote CW with RKI 1.05 and Sparkfun FT231X breakout board
I've created a workable solution for sending CW via a "straight key" to my remote Flexradio 6600 at the lake using RemoteKeyerInterface (RKI) and a simple Serial/USB circuit. RKI is only available for Windows. RKI enables you to use paddles or a straight key to send CW through a remote Flex‑6000 transceiver. After several iterations I've settled on a design using the Sparkfun FT-231x breakout board and RKI v1.05 that was originally posted by Gary KT7AZ on the RKI groups.io forum . However, to send CW reliably via a straight key - there were two main problems I had to solve. First, I had to resolve the network latency and buffer bloat in my shack's network by setting up a router with Smart Queue Management. The Ubiquity EdgeRouter was recommended by a friend of mine (Larry N1FG) and has been working great. I'm using the 4 port Edgerouter X which was only $50 at microcenter (open box special). No more audio stuttering or dropped packets, which kills
