What pollen people do?

Scientists definitely are multi-talented people. While we’re required to practice critical thinking on both our own and colleagues works, we also have to master many other skills. Apart from the acquisition of data, we need to properly store a numerical version of them, eventually to compute statistics on them. We need knowledge of graphical processing software to represent our results nicely, and write valuable scientific papers out of them. We sometime teach to students, that requires synthesis, pedagogic, and oral capabilities. We have to deal with paper work, which sadly tends to increase. We need to write applications for positions and/or for grants (and, ironically, so that we can do our job – are you going to the office and think “let’s first find the money to do my job”? – ). The list is endless, and there is no doubt I forgot important examples. Icing on the cake, we’re in an arena of competition, struggling for visibility and high impact factor (I should write about this guy, one day).

About one of the rarest pollen

Few days ago, I found a strange pollen grain that I couldn’t identify. All candidates I had in mind did not perfectly match what I could see at the microscope. Is it a strange Fabaceae, a strange Gentianaceae, a strange Helianthemum? No idea. Even with the rescue of my colleagues Burgi and Daniela, we couldn’t come to a convincing decision.

New year, new site

It’s been a month I haven’t posted anything here. Christmas and New Year holidays got me. Then the website has been under maintenance for a couple of days. Ironically, I’m currently enjoying all Star Wars movies (of course, in the right order). https://giphy.com/embed/ArrVyXcjSzzxe

Yoda is always a source of inspiration and motivation. So, I should not try to post here regularly, but just do it.

I’ve been busy last week performing XRF measurements. The XRF machine needs some attention every now and then, but otherwise leaves me quite some free time. I invested it in learning more what really happens behind the scene. Finally, this is another kind of these tools that I love: from a very simple mechanism, a lot is inferred. Human ingenuity really fascinates me!

I’m drafting some more posts at the moment, they’ll come in the next days 🙂

dat@osu

In the last years, it has been acknowledged that an important and significant proportion of valuable data produced by scientific institutions remains unpublished, or, worse, unmanaged. Such data aren’t visible at all, neither to the public audience—which often happened to have paid for them—, nor to the scientific community that could benefit from them.

stabiliseR, take 2

Some time ago I presented you a software to better estimate how relient palynological counting data can be, which I called stabiliseR. I’ve been working on a slightly different approach to represent the same information, and make it more appealing. I came to this animated bar chart:

As you can see, each taxa proportion gets closer to its final value as the total count increases, and variations tend to decrease. The tidyverse and ggplot approach/magic made it very easy to impletement. You first need the gganimate package and then to include a frame argument in your plot’s aesthetics.

This will create a normal plot, ignoring the frame argument. But the gganimate() function can actually understand what it means:

This will create a GIF in your working directory with as many different frames as values in the variable_to_animate provided to the frame argument. It’s that easy!

Follow a project's progress

As the end of a projet is getting closer, it is often time to show synthesis of the work achieved. For every project I’m dealing with, I keep up-to-date a (simple) Excel file of the samples I collected and analysed, but I thought about a nifty graph that could get the job done in a nicer way 🙂

Learning Qt

One year ago, I told a friend—who happens to be an expert in computer science—I have a dream project. I would like to create my own software. After defining my needs and strategy, he advised me to look for Qt. Qt is a language (C++-based) and environment for software and user interface development.

Recently, after a couple of frustrating experiences with the current solutions, I took the time and started to learn with language, thanks to video tutorials from ProgrammingKnowledge. So far I’ve learnt how to display text on the user interface, how to add push buttons, check and radio boxes, how to interact with user using dialogs, how to create menu options, and how to arrange all that in specific layouts and multiple views. The basic for building a user interface. Now, I need to learn the data handling that a software has to do at some point.

I’ll let you know about the progress 🙂 The big question is, what is this secret software I want to build…
