Dirk Eddelbuettel: RcppBDT 0.2.3
A new release of the RcppBDT package is now on CRAN.
Several new modules were added; the package can now work on dates, date
durations, "ptime" (aka posix time), and timezones. Most interesting may be
the fact that ptime is configured to use 96 bits. This allows a precise representation
of dates and times down to nanoseconds, and permits date and time
calculations at this level.
The complete NEWS entry is below:
Changes in version 0.2.3 (2014-04-13)Courtesy of CRANberries, there is also a diffstat report for the lastest release. As always, feedback is welcome and the rcpp-devel mailing list off the R-Forge page for Rcpp is the best place to start a discussion. Update: I just learned the hard way that the combination of 32-bit OS, g++ at version 4.7 or newer and a Boost version of 1.53 or 1.54 does not work with this new upload. Some Googling suggests that this ought to be fixed in Boost 1.54; seemingly it isn't as our trusted BH package with Boost headers provides that very version 1.54. However, the Googling also suggested a quick two-line fix which I just committed in the Github repo. A new BH package with the fix may follow in a few days.
- New module 'bdtDt' replacing the old 'bdtDate' module in a more transparent style using a local class which is wrapped, just like the three other new classes do
- New module 'bdtTd' providing date durations which can be added to dates.
- New module 'bdtTz' providing time zone information such as offset to UTC, amount of DST, abbreviated and full timezone names.
- New module 'bdtDu' using 'posix_time::duration' for time durations types
- New module 'bdtPt' using 'posix_time::ptime' for posix time, down to nanosecond granularity (where hardware and OS permit it)
- Now selects C++11 compilation by setting
CXX_STD = CXX11insrc/Makevars*and hence depend on R 3.1.0 or later this gives gives uslong longneeded for the nano-second high-resolution time calculations across all builds and platforms.

Wow. 3G delta. I haven t booted this laptop for a while I think I m finally ready to make the move from gnome2 to gnome3. There are bits that still annoy me, but I think it s off to a good start. Upgrading perl from 5.10 to 5.14.
For the past few years I've been running a simple service to block blog/comment-spam, which is (currently) implemented as a simple JSON API over HTTP, with a minimal core and all the logic in a series of plugins.
One obvious thing I wasn't doing until today was paying attention to the anchor-text used in hyperlinks, for example:

Zoe did indeed sleep in this morning, by a whole 30 minutes. It was nice. She
seemed no worse for wear for her lip injury, and it was looking better this
morning.
Wow, "bimonthly" is ambiguous. I had my "every two month" in person
co-parenting sync up lunch with Sarah today. Phew, that was a mouthful. Anyway,
I had that today, and normally that would fall on a Kindergarten day, but it's
school holidays. So we paid grandma and grandpa a visit, and they looked after
Zoe for me so I could make the meeting.
Mum and Dad have been away on a driving holiday, so Zoe hasn't seen them for a
while, and it's been even longer since we've been to their house. She really
loves going to their house because it's big, with a big back yard with a swing
set. There's all sorts of exciting things like grandpa's worm farm, a sand pit,
a china tea set, a piano, a tricycle and remote controlled cars. Zoe basically
just works her way around the house entertaining herself. It's great. I usually
get to put my feet up and read the newspaper.
After I got back from my lunch meeting, we headed over to Greenslopes Private
Hospital to visit my cousin, who's just had major surgery. On the way, Zoe
napped in the car. I made a brief side trip to clear my post office box along
the way.
Amusingly, Zoe wakes up from short naps in the car way better than at
Kindergarten. I don't know if it has anything to do with the quality of sleep
she's getting or what it is, but I easily woke her up and extracted her from
the car when we arrived at the hospital. No meltdowns. And that's pretty
typical of car naps.
I've had a discomfort in my right ear for the last couple of days, and it grew
into increasing pain throughout the day today. It got to the point where, while
I was driving home, that I deciding to get it looked at by a doctor, ASAP. One
of my favourite things about being back in Australia is the availability of
