Day *4* Q&A - HackMD

# Day *4* Q&A   - Zoom: https://uu-se.zoom.us/j/66409709879 Passcode: 583470 - Material: --------------------------------------------------- ## A coordinate in 3 dimensions What are their elements? - Richel: left, right, personnumber - Camille: cartesian or polar or spherical system of coordinates? You can pick, maybe a coordinathas x, y, z, system? - Pontus: x, y, z. - Harald: x, y, z/radius, azimuth, elevation - Jesper: x,y,z - . - x,y,z - [x,y,z] - Urs: x, y, z (struct) - - RJD : [x,y,z] - - bz: x, y, z - - ah: x, y, z ## A speed in two dimensions - Jesper: x,y; like a vector from origo (struct) - Pontus: x, y. ~~Class (x > 0, y > 0) ~~ - RJD: direction, velocity, acceleration; - direction, dx\/dt, dy\/dt - Urs: v (> 0, class) - Harald: v_x, v_y / angle, amplitude - Veector X, Vector y - v_x, v_y, both class - ah: x, y, speed/velocity - - - - - ## A circle - RJD: radius (non-negative, class); coord of centre (structure) - Camille: coordinates of the center (reusing the first class of the exercise?), radius > 0 --> class - Jesper: radius (>0), position of center (x,y) (class) - Pontus: radius > 0. Class - Urs: radius (> 0, class) + center coordinates x, y (struct) - Radius & center, class due to non-negative radius - Harald: center coordinate, radius (class) / list of coordinates (class?) - center (x, y), radius (r) - radius (diameter), x, y - radius (>0), origin (x,y) - A list of arbertrary coordinates that are on the rim of the circle[Lars trhowing a spanner in the works] ## A square - Camille: position of one corner + which corner + length of 1 side (>0) --> class - Urs: side length (> 0, class) + coordinates of a corner or the center x, y (struct) - position (x,y), side length (>0) (class) - coords for the four ends, restrictions on distance between points, non-negative distances or area so class - length, center - Pontus: width, height > 0. Class - corner point (x,y), length, width ## Class design? Which classes does the project need? Together: - make an alphabetic list of structures in the shared document - add exactly 1 maintainer to each struct Put the list on the GitHub project repository Form: - Bacteria (Bacterium): Camille - it looks like there is a duplicate below, isn't it? +1 - BactParam: bacterial characteristics - in case of different species e.g no of flagella, wall thickness, sugar preference (alex) - Bacterium (class): Pontus - Coordinate (x, y): Pontus - Environment (Space, nutrients, bacteria, temperature), Harald - Food concentration (class), Cormac - we have this redundantly (nutrients) - Motion type (run/tumble, timer): Jesper - Nutrients (coordinates, concentration), Urs - Run (length, direction, rotation), Josefine - Spin direction, Thanadol - Speed: Camille - Shape: Shape, size of the bacteria, Yuhe - Threshold : RJD: concentration threshold for initiating tumble - Tempreture put in enviromnt?, Harald - Tumble (direction, rotation), Josefine # Day 4 feedback ## What went well? - The pull request part was really imprssive - Found the pull request aspect of the practical useful +1 - Git pairing is more efficient - . - Hands on - Refelcting on earlier feedback +1 - CI is quite cool. HackMD is good for discussion - Testing proper git workflow +1 - Practising with opening issues, assigning them, opening pull requests on GitHub, as well as dealing with merge conflicts - Interactive - enthusiastic teaching! +2 - Nice practice time and pair coding - Going back to revise the pull requests. I learnt alot from that. +1 - Responded to feedback - Frequent breaks. +1 ## What held us back? - Made a mistake on a pull request and got time shortage for merge part - PR opened when the develop branch failed seems not update automatically when develop was fixed - correct pull request was overwirtten - exercise goals not always clear - Material should be more informative - Screensharing on linux - [Richel moved this to here] I couldn't start my own HackMD doc for live coding with subscribing. ## What can we improve? - Speed a litte bit to make decrease in the lecture part - More discussion around appopriate classes/structs for solving project. - Work with an established exercise - I would have liked more indept discussion about data structures and algorithms. Here you didn't say much more than that they are concepts you can use. (+1) - write some light program thats can actually do something, e.g., visualize the bacteria moving? - explain how to setup CI locally? so it automatically check the sutomation before push - It may sometimes make sense to be in groups of 3 (vs 2) - but I guess this is subjective - HackMD pages for shared coding? Maybe I missed it but I think it could be better than screensharing. - Students get thier own mini projects to go thru all the practices. Rather than scattered excercises. - state goals before each break out room
