R - MAKING A SLIGHTLY MORE COMPLEX TREEMAP
Hi ! A few months ago, I indicated that I wanted to show a way to represent treemaps in a slightly more advanced form.
R - INSTALL PACKAGES IN DIFFERENT WAYS
Hi ! Recently I had to debug a problem installing R packages with OpenBSD. To put it simply, I needed to use “httpuv-1.6.6 and +” but at the very end of the installation I collected a “core dump”. Since I haven’t found the reason yet, I’ll come back to this in a later post.
FREEBSD - CONVERTING IMAGES TO PDF (DEALING WITH 'ENCRYPTED FILES')
Hi ! I recently had another request to make a single PDF file from some small PDF files.
ZEEK - USING SOME INTELLIGENCE
Hi ! It’s time to talk a bit about the Zeek tool again. I’m not going to go into the details of what it is and allows you to do because there are sites that will be much better than me for this.
FREEBSD - USING SILK
Hi ! When we talk about seeing things, it is tempting to imagine the presence of images, but this is not always the case. Take the network, for example, knowing what’s happening at the data level involves capturing that data and analyzing it.
FREEBSD - CONVERTING IMAGES TO PDF
Hi ! I recently had a request to: Produce PDF documents from various images (5) in JPEG format; Make a single PDF file from the 5 small PDF files. My server at home is FreeBSD (yes, I use and abuse of “JAILS”) so let’s look at the software needed for the maneuver.
R - MAKING A SIMPLE TREEMAP
Hi ! I think you have understood that I find a representation of data in the form of a treemap very good.
GAWK - DEALING WITH NESTED COMMAS
A few posts ago, I was echoing the possible presence of nested commas in CSV file fields.
ZEEK - ADDING GEOIP TO 'CONN.LOG'
Since I’m a fan of seeing things, why not identify where the network connections are coming from. In the previous post, I talked about one of the strengths of Zeek which is the availability of packages. Precisely in the case that interests us, we will use the one named “geoip-conn”.
ZEEK - REPOSITORY FOR PACKAGES
Zeek is a very good tool for analyzing network flows and one of its great strengths is, in my opinion, the fact that it is possible to easily adapt it to your environment.
