Assumption: CSV file has a header and then lots of data.

Reality: My parser works fine!

After four years: PD has changed their outputs and now suddenly the header can appear in the middle because more non-static data has become available and all graphs are wrong from that point on.

Me: Time to dust off this project, reimplement the CSV extraction, change the graphing engine and redo the UI.

Life of a tools guy at work 🙂

#Dublin Bus has launched Dublin Bus Innovation (DBI), a new initiative to accelerate practical #innovation and improve customer experience in #Ireland. The launch includes a €60,000 seed funding challenge, divided into four €15,000 awards across #Data & #Visualisation, #Optimisation, Collaboration, and Smart #Cities. The company is inviting employees, stakeholders, and the public to submit bold ideas via its Innovation portal, with selected proposals receiving expert guidance and funding. Minister James Lawless highlighted DBI’s role in shaping Dublin’s future #transport, while CEO Billy Hann said it supports the city’s evolving mobility needs.

Everybody knows Escher's waterfall picture: A perpetual motion machine where water from the base of a waterfall appears to run downhill along the water path before reaching the top of the waterfall.

The house at the bottom left, that is at level -1 when you are at the top of the waterfall, and level 0 or higher when you take into account that water flows down, back to the top of the waterfall here.

At https://maps.app.goo.gl/yi7uqCZrk9tfiNWF7, you will see the front of the Cincotta Chemist. It's at street level 0. Zoom out a little bit and then look at the other side of the building, at https://maps.app.goo.gl/gGzBdaqtnodKcm5H6.

At street level 0 (if that stupid truck wasn't there....) you would see the entrance of the Caringbah family practise, and next to it you have the escalator ("Lift to shops") to the Cincotta Chemist.

I've been trying to get the shops in my area in the OpenStreetMap, properly with levels etc. This Cincotta Chemist is both at level 1 and at level 0, the same as the house on the Escher's waterfall. Or the escalator is going from level 0 to level 0. I just cannot get it working.

At the end I just ignored the escalator. ignored that there is a part of the chemist above the doctors, and everything is happy in my head now.... (Except for that gnawing feeling that there is a part of the map wrong)

The image depicts a watermill with an elevated aqueduct and waterwheel as the main feature. The aqueduct begins at the waterwheel and flows behind it. The walls of the aqueduct step downward, suggesting that it slopes downhill. The aqueduct turns sharply three times, first to the left, then to the right, and finally to the left again. The viewer looks down at the scene diagonally, which means that from the viewer's perspective the aqueduct appears to be slanted upward. The viewer is also looking across the scene diagonally from the lower right, which means that from the viewer's perspective the two left-hand turns are directly in line with each other, while the waterwheel, the forward turn and the end of the aqueduct are all in line. The second left-hand turn is supported by pillars from the first, while the other two corners are supported by a tower of pillars that begins at the waterwheel. The water falls off the edge of the aqueduct and over the waterwheel in an impossible infinite cycle; in his notes on the picture, Escher points out that some water must be periodically added to this perpetual motion machine to compensate for evaporation. The use of the Penrose stairs is paralleled by Escher's Ascending and Descending (1960), where instead of the flow of water, two lines of monks endlessly march uphill or downhill around the four flights of stairs.[2]

Frockly - Vos formules Excel enfin visibles et manipulables

https://fed.brid.gy/r/https://korben.info/frockly-formules-excel-blocs-visuels.html

<p><strong>RyuU12358</strong> n'est pas un personnage de manga cyberpunk... Non, c'est un développeur japonais qui a eu une idée toute bête. Il s'est demandé si on pouvait VOIR la structure des formules Excel au lieu de les lire comme on lirait un roman écrit en russe ?</p>
<p>Parce que bon, les formules de tableur imbriquées, c'est le cauchemar de pas mal de monde. Vous savez, ce genre de truc : <code>=IF(AND(SUMIF(A:A,B2,C:C)>100,VLOOKUP(D2,E:F,2,FALSE)="OK"),CONCATENATE(G2," - ",H2),"Erreur")</code>.</p>
<p>Et encore, j'ai pris un exemple gentil.</p>

<p>Le problème, comme le souligne très justement le créateur, c'est pas que ces formules sont complexes. C'est que leur structure est planquée à l'intérieur d'une seule ligne de texte, du coup, à chaque fois qu'on doit les modifier, on repart de zéro pour comprendre comment tout s'imbrique.</p>

#TIL about a data visualisation system called #Got;

"got protocol and all client side / frontend tools are open source
Mainly driven by the GotHub Team
GotHub and our work is funded by operating the GotHub.io platform and other alongside services
GotHub.io is a hosted Got-Provider"

Anyone know anything about this?
