I don't use it very often but I may have to update the "I have strong skills in python" part of the CV
>>> def add_two_nums(): num1 = input("Enter the first number you want to add: num2 = input("Enter the second number you want to add: ") if num1.isdigit() and num2.isdigit(): pass else: print("Error: One or both of the numbers you entered are not numbers. Enter a number numbskull") sum = num1 + num2 print(f"The sum of the two numbers is: {sum}") ... add_two_nums() Enter the first number you want to add: 6 Enter the second number you want to add: 7 The sum of the two numbers is: 67

Quick sunburst plot in python this morning. Better labelling of each layer would have been nice but I couldn't work it out

Just found out that pressing Tab in the Linux Terminal autocompletes the file name. So much time checking spelling and making mistakes that could not have been wasted.

Popped onto my Windows partition because I needed a Windows program. It decided to update itself without asking. It's now nerfed my Linux partition somehow and copilot has reactivated itself on the windows side.

Luckily everything is backed up.
It's time to wipe the laptop and go all in on Fedora

Has flashbacks to his master's thesis they he thought would be a good idea to write in LaTeX in RStudio
freecodecamp.bsky.social freeCodeCamp.org @freecodecamp.bsky.social · Dec 20
LaTeX is a typesetting system you can use in technical & academic writing. And website-based apps like Overleaf let anyone read, write, & compile LatTeX-based scripts online. But here Fahim shows you how to run your LaTeX projects locally (& for free) on Windows.

One has to ask, did they even bother with a power review?

Still the paper got traction on the BBC and other news websites and, in the end, that's all that matters

You remember that Nature Aging paper about how multilingualism protects against accelerated aging? Well…

Here's a good one. Rendering my quarto html in #positron causes loads of errors implying that quarto isn't installed correctly (I've uninstalled and reinstalled multiple times) but if render the same html in #RStudio, it renders with no drama

Anyone here better with the ggsankey package than I am? - I am trying to label the flow with the number of people transitioning through each stage. I have found no examples on the internet of labeling the flow (plenty labeling the nodes).

I have below what I need to try

Looked at the percentage of Oxbridge educated people who have won various British Literary Prizes for #TidyTuesday. I used ggbrick and, as the bricks of look like books, tried to make it look like they were in bookshelves with meh results.

If anybody has any good tips/resources for a statistical programmer who has a technical interview as a data scientist, let me know. I've not done one before

(Background is epidemiology and clinical trials but this would be in health data science looking at massive datasets)

As a Welshman, taking the opportunity to ignore the English and focus only on Wales for #TidyTuesday. Looking at the average weather for Wales in 2024 and now I've made myself homesick.

I do like #positron but RStudio allows me to create .tex files from new.

Anyone know how I could get this on #positron, or is not a thing yet?

Tried the datapasta package out, which is a form of minor miracle to get the country codes for the players.

Managed to crack a map of grandmasters per country before flying home to the UK for a break
