A new release 0.4.16 of RQuantLib arrived at CRAN earlier today, and has been uploaded to Debian as well.
QuantLib is a very comprehensice free/open-source library for quantitative finance; RQuantLib connects it to the R environment and language.
The release of RQuantLib comes agaain about four months after the previous release, and brings a a few small updates for daycounters, all thanks to Kai Lin, plus a small parameter change to avoid an error in an example, and small updates to the Docker files.
Courtesy of my CRANberries, there is also a diffstat report for the this release. As always, more detailed information is on the RQuantLib page. Questions, comments etc should go to the new rquantlib-devel mailing list. Issue tickets can be filed at the GitHub repo.

After two long years of COVID hiatus, local Debian events in Montreal are back!
Last Sunday, nine of us met at 
If everything goes according to plan, our next meeting should be sometime in
June. If you are interested, the best way to stay in touch is either to
Finally, TIL, what can all be the reason for systemd services to hang indefinitely. The internet is flooded with numerous reports on this topic but no clear answers. So no more uselessly marked workarounds like: 
AX.25 is a tough protocol to use on UNIX systems. A lot of the support in
Linux, specifically, is pretty hard to use, and tends to be built into the
reptilian brain of the kernel. 
I first heard Virginia Astley via Lauren Laverne, who played (I think) "With my
eyes wide open" from her first album, "From Gardens Where We Feel Secure". Mostly
ambient, a conceptual piece about a garden in an English Summer, spanning dawn to
dusk. Bucolic ambient, dream pop.
It was a little outside my wheel-house, but I loved it, and wanted to find out
more. I soon learned that official, physical copies of it were rare and
expensive.
Previously: 
Traditional network access controls work by assuming that something is trustworthy based on some other factor - for example, if a computer is on your office network, it's trustworthy because only trustworthy people should be able to gain physical access to plug something in. If you restrict access to your services to requests coming from trusted networks, then you can assert that it's coming from a trusted device.
I wanted to understand how kids between 10 and 18 conceive the internet.
Surely, we have seen a generation that we call digital natives grow up with
the internet. Now, there is a younger generation who grows up with pervasive
technology, such as smartphones, smart watches, virtual assistants and so on.
And only a few of them have parents who work in IT or engineering
The youngest respondent, a 9 year old girl, drew a screen with lots of people
around it and the words film, series, network, video , as well as a play
icon. She said that she mostly uses the internet to watch movies. She was the
only one who used a shared tablet and smartphone that belonged to her family,
not to herself. And she would explain the net like this to an alien:
A 10 year old boy represented the internet by recalling user interface
elements he sees every day in his drawing: a magnifying glass (search
engine), a play icon (video streaming), speech bubbles (instant
messaging). He would explain the internet like this to an alien:
A 12 year old girl imagines the internet like a second, intangible, planet
where Google, Wikipedia, Facebook, Ebay, or H&M are continents that one enters
into.
A 15 year old boy knew that his family s devices are connected to a home router
(Freebox is a router from the French ISP Free) but lacked an imagination of the
rest of the internet s functioning. When I asked him about what would be behind
the router, on the other side, he said what s behind is like a black hole to
him. However, he was the only interviewee who did actually draw cables, wifi
waves, a router, and the local network. His drawing is even extremely precise,
it just lacks the cable connecting the router to the rest of the internet.
A 17 year old girl would explain the internet to an alien as follows:
That s why a discussion space about saying NO did not seem out of place
at the feminist hackers assembly :) I based my workshop on the original,
created by the Institute of War and Peace Reporting and distributed
through their holistic security training manual.
I like this workshop because sharing happens in a small groups and has
an immediately felt effect. Several people reported that the exercises
allowed them to identify the exact moment when they had said yes to
something despite really having wanted to say no. The exercises from the
workshop can easily be done with a friend or trusted person, and they
can even be done alone by writing them down, although the effect in
writing might be less pronounced.
