Professor essentially doing a dance to show data visualisation:
“Hey pay attention! I’m trading my dignity for your education”

Wow my job sucks right now. Un fuckin believable.
I got hired a month ago as a programmer. Everything went fine at first, then my Boss asked if I could do 3D modeling, and I could, I used Maya for 4 years, but I told him I only can do simple low poly models. A partner company of ours needed some help in their 3D department and I had to help.
Well, I thought, a small 3D project from time to time would be nice and refreshing, especially since it was very easy geometry, my Boss even showed me some previous projects and That was totally doable even for me.

So i started out making the first few models in blender, because we dont have anything else. After a day of getting used to blender i sent off the first models and it all began.

They wanted detailed, high poly models of some mechanical parts, my Boss originally told me it was just an abstract visualisation... fuck me...

Well I agreed to it so had to do it. The partnering Company started to change things, seemingly at random. Had a model completely modelled, textured and animated, now they want to change the model so I have to redo the UVs, the texture and the Animation god fucking damnit.

But still I thought ok, its only for a bit. Now my boss accepted even more work. Because of endless reworks I couldnt finish even one model and have to already make the new ones.

Now my boss is pissed because that company is pissed that i cant know what they want.

Big pile of misscommunication.
I hope this is over soon but I overheard that more is coming...

I just lost faith in the entire management team of the company I'm working for.

Context: A mid sized company with
- a software engineering departmant consisting of several teams working on a variety of products and projects.
- a project management department with a bunch of project managers that mostly don't know shit about software development or technical details of the products created by engineering.

Project management is unhappy about the fact that software engineering practically never sticks to the plan regarding cost, time and function that was made at the very beginning of the project. Oh really? Since when does waterfall project management work well? As such they worked out a great idea how to improve the situation: They're going to implement *Shopfloor Management*!

Ever heared about Shopfloor Management? Probably not, because it is meant for improving repetitive workflows like assembly line work. In a nutshell it works by collecting key figures, detecting deviation in these numbers and performing targeted optimization of identified problem areas. Of course, there is more to Shopfloor Management, but that refers largely to the way the process just described is to be carried out (using visualisation boards, treating the employee well, let them solve the actual problem instead of management, and so on...). In any case, this process is not useful for highly complex and hard-to-predict workflows like software development.

That's like trying to improve a book author's output by measuring lines of text per day and fixing deviations in observed numbers with a wrench.

Why the hell don't they simply implement something proven like Scrum? Probably because they're affraid of losing control, affraid of self managed employees, affraid of the day everybody realizes that certain management layers are useless overhead that don't help in generating value but only bloat.

Fun times ahead!

Good Visualisation.

Time to rant about JavaScript tutorials.

If you don't know the 'jQuery basic arithmetic' joke, Google it now. It'll make you laugh, promised.

In that manner i just remembered a JavaScript tutorial my fiancee tried to follow when she did an internship at the company i work for last year.

She was tasked to create a temperature interface for our server rack, which she wanted to do via an Arduino and a webserver aswell as an SQL database.

The Arduino part wasn't really a problem, but since she had no experience with js she very closely clinged to a chart visualisation tutorial.

All of that worked very well, but beeing the person i am i looked at the code and found something off.

The chart library had no dependencies to external libraries or any local files for any of them. Though the tutorial used a jQuery import.

So why did it use jQuery?
Well...
To load the chart initialization after the page has loaded.

So they pulled the entirety of jQuery in just to do what fucking window.addEventListener('DOMContentLoaded',function(){...}); could have done.

I wonder how many people who just want something to work did this shit. I hate it that so many tutorials do not adhere any kinds of standards, override behavior because they don't like it, even though it may have a very good reason to exist, pull entire libraries in for something vanilla <language> can do in 3 lines, etc.

Fuck.

aaAAaaAaaAaaAaAAAAAaAaaa floating points!

I debugged my algorithm for quite a while, wondering why it sometimes gives out "Circle(Point({1.7976931348623157E308,1.7976931348623157E308}),1.7976931348623157E308)" as the smallest circle around a group of points.
Figured out that it sometimes just never found any circle defined by two or three of the points which included all points (which is mathematically impossible).
Then finally I made it print out the points it thought were not inside the circle:
"1,7,8: Circle(Point({0.6636411126185259,0.535709780023259}),0.4985310690982777)
skip, 1 not inside"
So it defined the circle with 1 being on the edge, but then thought 1 was outside. Thank you, floating point Math.

For anyone wondering about the notation: That way I can directly copy/paste it into Geogebra to have a visualisation.

Literally removing the sleep(10);

Nah jokes aside, reworking my entire code from scratch based on what I drew up on a board.

Sometimes visualisation of processes and control flow can really help you write better code.

Project idea: make a fucking neural network visualizer, that gets my fucking model and gives me a proper fancy fucking visualisation in jpeg. 😐

I'm angry cuz I have to make that shit manually rn, and shit ain't playing nice.

Generally devs who are too arrogant to accept help or constructive criticism. There’s this data visualisation library that missed a specific feature that psychologists use quite frequently, so I added it myself and opened a PR. The maintainer closed it because people should use whatever he’d already implemented. It’s like not giving someone the option to listen to disco because rock music is better. Yeah, cool story bro. Now all my visualisation projects depend on my fork instead. Same with the now abandoned Material Design Library devs. They didn’t have a drop down with free input, so I opened a PR with my solution. Closed as it was out of scope, simply because Google didn’t specifically include that in the Material specs, only an input and a drop down separately which my solution matched. I also opened a PR for an obviously missing feature (being able to validate forms via JS), closed as this behaviour wasn’t in the Material specs either. No wonder MDL died before it was ever finished.

@lazyDev reminded me of the time my bid for a project was rejected because I'm a white man. Never mind the fact that I have built my career around data management, visualisation and modelling and the only other competing bid was from someone who had experience in mobile development and little else. I checked up on the company and the project just now, and they've posted the project up again. I've made a bid just like I did before, only this time I've tripled my price. Let's see if they change their minds.

Should i be posting on devRant to hire a fellow devRanter for a project in my company? (temporarily but may become constant if we click well)

More info:
Looking to hire a mostly frontend react dev.

The project is about graph visualisation and traversal.

Our stack is python (flask, appbuilder, SQLalchemy), react, react d3-graph, jest.

Must know how to use git and pull-requests.

(The software is based on Apache superset)

The code is a bit of a mess. But let's be honest, which big project isn't?

The challenge of interesting side projects is that it's not just the thing. It's the thing then a whole-ass visualisation library. Or tooling for whatever stupid thing I want to do.

Also then I get bored and start on the next thing.

Just sat through a demo of some clicky-draggy data visualisation stuff.

The guy showed us how you can write a custom script that takes a user input and pokes it into a sql command using string concatenation, so a very obvious injection vulnerability.

Ok, so it's only a demo. But you wouldn't do a demo with an example user called Captain Cock, so why do a demo with a screamingly obvious security hole?

Whole thing was basically pivot tables in a short skirt anyway.

What's your favourite Data analytics/ visualisation tool? and why ?

How can you create Histogram Visualisation using python?

Was using an open source piece of software for data storage and visualisation to work with the loggers my company makes. When importing old data for historical views, some of the csv imports would fail without any specific error messages.

It took me a couple of hours but after looking at their csv parser and making my own little one to test with, I eventually found out that it was all down to the way datatime (I think it was?) in java deals with DST, which apparently was to just fuck shit up.

Anyhow, a few simple lines added into the parser later and it all works just fine.

Was super proud of that one as it was the first time I actually looked somewhat good in front of my senior dev.

Power BI: wonderful tool, pretty graphics, and can do a lot of powerful stuff.

But it’s also quite frustrating when you want to do advanced things, as it’s such a closed platform.

* No way to run powerquery scripts in a command line
* Unit testing is a major pain, and doesn’t really test all the data munging capabilities
* The various layers (offline/online, visualisation, DAX, Powerquery, Dataset, Dataflow) are a bit too seamless: locating where an issue is happening when debugging can be pain, especially as filtering works differently in Query Editing mode than Query Visualisation mode.

And my number 1 pet peeve:
* No version control

It’s seriously disconcerting to go back to a no version control system, especially as you need to modify “live code” sometimes in order to debug a visual.

At best, I’ve been looking into extracting the code from the file, and then checking that into git, but it’s still a one-way street that means a lot of copying and pasting back into the program in order to roll back, and makes forking quite difficult.

It’s rewarding to work with the system, but these frustrations can really get to me sometimes

Multiple questions :
Who shall do the d3 driven data visualisation - which role?
Where are the asp.net people?
Why automation companies work preferably in asp.net?

Which Java GUI shall I learn in 2021? I see people are demonizing swing and telling its obsolete, so it would be really helpfull if someone gives an nice Java stack example for developing windows application focused on PLC and other external controller like arduino, raspberry etc, control and visualisation., in general, automation and industrial monitoring and controls.

I got to a point where I have a multi-level recursive promises within loops and my mental map is by far not enough to process this. I wish there were some visualisation tools for this - though I don't even know how it could look like. All I know is that at some point I'm returning a wrong promise and the recursion is not correctly handled.

I wouldn't be doing THAT alternative job,

but i guess doing archvis would be an idea. Or doing other 3D visualisation stuff such as creating furniture or stuff like that. Seems to pay well.

It just has to be something, where you can be creative, while also not being held like a slave.

i dunno man
