I want to announce a new scientific journal: Open Research Computation.
I think it sounds quiet interesting, citing their aims & scope:
Open Research Computation publishes peer reviewed articles that describe the development, capacities, and uses of software designed for use by researchers in any field. Submissions relating to software for use in any area of research are welcome as are articles dealing with algorithms, useful code snippets, as well as large applications or web services, and libraries. Open Research Computation differs from other journals with a software focus in its requirement for the software source code to be made available under an Open Source Initiative compliant license, and in its assessment of the quality of documentation and testing of the software. In addition to articles describing software Open Research Computation also welcomes submissions that review or describe developments relating to software based tools for research. These include, but are not limited to, reviews or proposals for standards, discussion of best practice in research software development, educational and support resources and tools for researchers that develop or use software based tools.
You may also be interested in a more detailed announce: Can a journal make a difference? Let’s find out.
Just wanted to create an expression, existing of some mathematical annotation and a value of an R object. Wasn’t that intuitive!
Each single goal is easy to reach, for example to combine a value of an R object with text just use
To have a plot title with an \(\alpha_1\) you can use
But to let the the title of a plot contain objects and Greek letters isn’t that easy. Those of you who think it’s just about combining
expression might try it on their own and come back head-ached after few minutes of unsuccessful testings.
The problem is, that
expression interprets chars as expression and not as object identifier, of course, how should it know whether you mean the var
alpha or the Greek letter!? The solution is called
substitute ! With
substitute you can replace objects inline, here is a small example:
substitute got a list what to substitute and replaces the
paste with the content of
var . Run
eval to evaluate to result:
Now it’s easy to create a more complex plot title:
Go out and produce imposing graphs! (-;
Here is the error:
Aha, too many open files.. So I had to install everything piecewise in a disturbing manner..
iptables 1.4.6-2 -> 1.4.10-1 before
xtables-addons-common 1.23-1 -> 1.26-2 is a bad idea and fails for some reasons. So try to do it the other way round.
if you haven’t noticed yet: SSL is turned off…
Of course it isn’t really turned off, all content is still available through encrypted connections (all links are still working), but it’s disabled by default.
I got a lot of mails during the last weeks, telling me that there is a problem with my SSL cert.
Yes, your browser is completely right, my cert isn’t valid because I’ve signed it by myself.. To get a trusted certificate that your browser recognizes to be valid is very expensive. For a cheap one I still have to pay about $100, that’s neither worthy nor affordable for me and my private blog. But I’m always interested in ideally offering secure mechanisms, so I tried to provide SSL.
Another reason for SSL was my auth stuff. Wordpress doesn’t provide both SSL and SSL-free access. In an installation you have to decide whether to use
http://... for URL’s. So all links are either to SSL encrypted content or the next click is unencrypted. Don’t ask me why they don’t check whether SSL was turned on/off for the last query and decide afterwards on using SSL for all further links.. However, I didn’t want to authenticate myself unencrypted and so I enabled SSL by default.
To be congenial to my visitors I turned off SSL, until somebody sponsors a valid certificate. There are also many disgusting tools having problems with my website, so it might be the better way to deliver unencrypted contend. The information on my site isn’t that secret ;-)
As a consequences you aren’t able to register/login anymore. I scripted a little bit to find a secure way for authenticating myself, but you aren’t allowed to take this path :-P Nevertheless, comments are still open and doesn’t require any authentication.
If you can find any SSL zombies please inform me!
