The PDL project is starting a quarterly colloquium on subjects relevant to PDL users. The colloquia is a great opportunity to learn about PDL, as well as socialize and meet other PDL users.
If you are not a developer, but would like to contribute to PDL, please consider doing a presentation for a colloquium. Please write to the PerlDL list if you are interested.
TITLE: Introduction to PLplot - A modern scientific plotting library
DATE: TBA Tell us when you can come
TIME: TBA Tell us when you can come
WHERE/HOW: Slideshare, IRC, and VoIP. See the instructions below.ABSTRACT: PLplot describes itself as
a cross-platform software package for creating scientific plots. To help accomplish that task it is organized as a core C library, language bindings for that library, and device drivers which control how the plots are presented in non-interactive and interactive plotting contexts.In this talk, I will focus on using PDL's binding for PLplot, created by Doug Hunt. The bindings for PDL come in two flavors. The high-level commands are meant to create nice plots with one or two lines of code. The low-level commands are tied to PLplot's C bindings and although they are more powerful than the high-level commands, they are also more tedious. In this talk, I will explain both sets of commands, starting with the high level commands.
FORMAT: 45min presentation using Slideshare and VoIP followed by Q&A and open discussion.
None yet. This section will have links to webcasts of previous presentations with slides and audio.
In order to participate in the colloquium, you will need the following up and running:
- A web browser. The slides will be posted on Slideshare, so you will need a browser in order to view them.
- An IRC client, or use mibbit. We will use IRC (internet chat) to coordinate who is speaking during the open conversation and possibly to pick a SIP conference room before the talk gets going. The IRC channel will be the #pdl irc channel on irc.perl.org. If you don't have an irc client or don't want to download one, this link will start a mibbit session for you on the channel.
- A SIP client. When you think VoIP you probably think skype, but skype does not allow for large gatherings of people at the same time. Instead, we will use a similar but free technology called SIP. You can find SIP clients from this handy wikipedia page. You'll need to install your client and be sure it works before coming to the colloquium, or you won't be able to hear the speaker.
A couple of notes for how the colloquium will likely be conducted:
- Throughout the talk, the speaker will be responsible for directing the audience through the slides. This is very similar to what you would experience with a conference call, so the speaker will say things like "Moving onto slide 12, we see ..."
- If you have a short question during the talk, you can post it directly to irc and let the speaker answer the question. If you have a long question, you can post on the irc channel something like "I have a question." The speaker can then acknowledge your question when they come to a good stopping point.
The audio portions of the talk, and possibly the open discussion afterwards, will be recorded and may be distributed. By participating, you agree that you are OK with us distributing that audio, including things that you may say.
We will record the talks so that we can turn the slideshow into a slidecast, which ties slide transitions to certain points in the recording. If we keep this up for a number of talks, we will have a number of media-rich talks on how to use various facets of PDL, providing a nice alternative to our written documentation.
Recording the discussion will also allow us to create effective slide notes making the information content of the audio more amenable to archival and searching operations.
