Press release here. CP/M was significant in the history of the development of the IBM PC as IBM famously approached Kildall to license CP/M for the OS for the first IBM PC, but failing to work a deal approached Bill Gates at Microsoft instead.

Ars Technica has a fantastically detailed review (25 pages) of the latest OS X release, Yosemite. I’m browsing though the article as my 5.1GB download is slowly coming across the tubes. Maybe sometime tonight it will have completed and I’ll be ready to install
In the meantime, I’m wondering whether I like the ‘flat’ UI look, and prefer the 3d style icons and shadows in my dock, but I’m sure I’ll get used to it.

MCON ON : monitor all packets to/from other stations, not just your station
MCOM ON: monitor all packets sent (including ack packets etc)
MONITOR ON: turn on monitoring while not connected

Just tried to start up Parallels and got an error message that the Parallels service could not start – the link to this article says this is due to the last OS X update, and there’s a link to a download for an update to Parallels to address the issue.

I’m still learning what the different commands are, but here’s what I’ve worked out so far (some of this might be wrong, if so leave me a comment!)
- c callsign : connect to callsign
- c callsign1 via callsign2 : connect via some other station you can hear
- unproto name via call1, call2, etc : sets the routing list of stations where your want your packets to be sent when in conv mode (?)
- when you connect (c) direct to another station, you enter conv mode with that station
- conv: enter conv mode when not directly connected to another station (packets are broadcast to the stations in your unproto string)
- Ctrl-C : to exit conv mode, and get back to cmd: mode
- perm : write settings to eprom
Useful commands when connected to someone’s bbs:
- l : list all messages
- lm : list messages to me
- b : list broadcast messages
- s callsign : send message to callsign
- r # : read msg #
- b (bye) : exit

I’m transferring some apps downloaded for my Atari ST (don’t ask) to floppies that are formatted with 80 tracks and 8 or 9 sectors, on double density disks (formatted on the ST). From what I understand these are MS-DOS readable but not exactly FAT format. Anyway, they don’t seem to mount by default on Ubuntu as it doesn’t know what format they are, but forcing a mount with this seems to work:
sudo udisks --mount /dev/fd0
seems to do the job (tip from here)

Since having my Amateur Radio license just over a year, I’ve yet to go all out on a contest and work every hour permitted, but I have enjoyed the opportunity to work some contacts for my log. Last year’s California QSO Party I only worked a few QSOs. If I remember back to last year, I did call CQ for 20 mins or so and didn’t get any takers, so did some search and pounce and picked up a handful of contacts:This year I worked a couple of hours over Sat and Sun, and got significantly more that my 8 QSOs last year, but nowhere close to K6Y’s score. I’ve submitted my log and will wait for the final scores to be published All in all, had a good result this year!

I’ve used Log4J 1.x for ages, and not even realized that the 1.x code line is not maintained any more, it seems all the activity is on 2.x as the latest maintained version of the framework.
To move from 1.x to 2.x, there’s a few changes:
If you’re using Maven for your dependencies, replace
The API has changed from:
Sample xml config – use filename log4j2.xml instead of log4j.xml (or log4j.properties):
<?xml version=”1.0″ encoding=”UTF-8″?>
<Console name=”STDOUT” target=”SYSTEM_OUT”>
<PatternLayout pattern=”%C – %m%n”/>
<Logger name=”example.logger.name” level=”debug”/>
Additional useful info here.

The messaging subsystem in Wildfly is enabled in the standalone-full.xml config (not standalone.xml).
To add a new queue, search for <subsystem xmlns=”urn:jboss:domain:messaging:2.0″>, and then within the <hornetq-server> section, add a new <jms-destinations> if it doesn’t exist already, and define your queue name and JNDI lookup:

JavaOne 2014 wrapped up today, and was another great year, with plenty of awesome sessions. James Gosling played an active part in the Q&A during the Community Keynote this morning, and also gave a retrospective of the development of Java. He was wearing one of his Nighthacks Diner shirts, which I think we’re given out as a special prize at a JavaOne several years back (based on the painting by Edward Hopper, ‘Nighthawks Diner’). I seem to remember the design on this particular shirt, so did some digging in my photos from JavaOne conferences in the past, and here you go:
This is from JavaOne 2009 – I believe James was visiting some of the exhibitions in the Exhibition Hall:
And from this morning during the Community Keynote:
