Adding an efficient, higher-level project view layer to Things 3: a proposal

Task manager applications are great. They help you get things out of your head and easily accessible. One of the major issues with task manager applications is higher level planning, particularly on the fly decision about committing or not a new project. This is because you need in one look an overview of everything going one right now, including deadlines. This is something not easy to do only with a Task Manager and your electronic calendar apps. Also for what I am thinking about, a planning software is not that useful either. I tried OmniPlan for that purpose alone, maintenance is higher than I would like and I am still not convinced this is the best way of doing it.

A Truely Portable 2TB Backup Drive – the Samsung SSD T5

I was recently in need of a new portable backup drive that uses directly a USB-C or Thunderbolt 3 port to go with my new MacBook Pro. I saw a few SSD options and asked my University store. I was propose the tiny, 51g (1.8 oz) 2TB Samsung T5 drive. If like me, you have been using computer for a long time, boy is this unit small for 2TB capacity. I still remember a time were we would leave the home computer ON once we have program a game (from a printout you would get in a specialized computer magazine) because there was no saving option…

Free, multi-platform pro-like applications for students

Free software is software that gives you the user the freedom to share, study and modify it. We call this free software because the user is free

Going through graduate studies (or even undergraduate studies), is about creativity, hard work and learning not to loose information, not to drop the ball on ideas and projects. In order word, part of it is also about being able to put your ideas to work for you in an efficient manner. In the following are a few applications to help you along the way. Of course, nothing precludes the good old pen and paper. I personally really enjoy my Lamy 2000 fountain pen and a Leuchtturm 1917 whitelines notebook (but this is for another post!).

Things 3: clean, efficient and simply beautiful!

Ever since moving all of my projects an tasks planning digital, I have used a dedicated task manager. I started with Cultured Code Things over 11 years ago with the very first beta; something like version 0.7b – can find my old e-mail about it. When it came out, Things was not only the most intuitive and beautiful dedicated task manager on the market but also the best (at least mac-wise).

A new list of predatory (blacklist) journals is available…for a fee

Beall’s list of predatory journals has found a “commercial” replacement. Let’s see how much it will cost to access.

Exciting!

New opening for MSc and PhD students in our research group

See the announcement in French and English for all the details. Our graduate program is CAMPEP accredited. Please note that formal teaching is done in French but research activities can be conducted in English.

We are located in the middle of the Old Quebec City, classified as a UNESCO world heritage treasure.

New publication by our group on Quantum Dots as radiation nano-dosimeters.

Systematic characterization of semiconductor colloidal quantum dots (cQDs) response to ionizing radiation must be performed to use them in radiation detection. In this study, the robustness of multi-shell (MS) and core/shell (CS) cQDs was investigated under irradiation. Radioluminescence (RL) measurements with kV and MV photon beams revealed a better resistance of MS cQDs to ionizing radiation, with their spectra fluctuating by barely ∼ 1 nm. A systematic signal recovery between subsequent irradiations was noticed for MS cQDs only. A beam energy dependence of the RL stability was detected between kV and MV energies. At the same point of dose cumulated, the RL signal loss for the kV beams was observed to be ∼6-7% smaller than that of the MV beam, for both types of cQDs. These results demonstrate that MS cQDs are better candidates as ionizing radiation sensors than CS cQDs, especially in the kV energy range.

PLOS ONE: How Many Is Too Many? On the Relationship between Research Productivity and Impact

Clearly if you do not published, you can never be cited…However, interesting to see that the Natural sciences field seems to taper-off more quickly than the life science field.
