ImageXav··on UK: No-fault evictions to be banned in reform of rental sector
Someone earning $125k in London is in the top 1% of salaries. They would be able to quickly save up enough for a deposit. Not many 25 year old are making that, even in tech!

The Median salary in the UK is around £34000 last I checked on the ONS website. Anyone in London on the Median income is struggling at the moment due to high rents, energy bills and food costs.

ImageXav··on Ask HN: What desktop to buy for home based AI/ML in 2023
Not at the moment. I have a few hypotheses that I'd I'd like to test and I've reached the bounds of what Colab can do.

I was thinking of going for a 3090 but wasn't sure whether it was worth it due to the price still being quite high, it would certainly blow my budget out of the water. What kind of models are you planning on using it for?

AMD Ryzen 9 processors definitely seem worth looking into though, thanks.

The problem with Colab is that I tend to run into two issues:

1. Disconnect during training 2. Not enough storage

I tends to work on somewhat mid/large models and TB+ datasets so I run into these issues frequently enough that it's become a hurdle I want to avoid going forward. I suspect this might make online compute expensive too though I've not looked at pricing plans. Where would you recommend buying personal cloud compute?

ImageXav··on Python 3.12.0 is to remove long-deprecated items
How does pyenv compare with conda, mamba, pip and poetry? I typically use conda but ever since they broke with python 3.10 I have been considering moving to other environment managers.
ImageXav··on Ask HN: What are some of the best books you have read in 2022?
Ursula Le Guin has a gift for punchy prose. I've also read The Dispossessed and The Left Hand of Darkness by her and her ability to come up with truly novel, unique storyline and views of the world is incredible.
ImageXav··on A look inside Feynman’s calculus notebook
What strikes me here is the willingness of the father to equip Feynman with the right tools and admit to his shortcomings. The 'practical man' series also sounds interesting. Is there an modern version of these books? Or do the originals stand the test of time?
ImageXav··on Buddhism has found a new institutional home in the West: the corporation
I suspect you might enjoy reading the rest of the article. It goes into some depth on what Buddhism was, is and how it has been adapted in the West to mostly focus on meditation and why. Rather than a critique of "Western Buddhism" it is an exploration of it in a wider context. The term appropriation might have been off-putting due to its current cultural load, but in this context it is not wrong.

For others that are curious about meditation and Buddhism, I would suggest reading the article and making up your own mind, rather than the comments here.

ImageXav··on Ask HN: Which book would you pick to re-read for the rest of your life?
I would have to say Bertrand Russell's The Problems of Philosophy. A short book, it covers the limits of knowledge and how to think about the world.

Every time I read it I discover something new, and it would be a good companion guide through life if I could read nothing else.

ImageXav··on Python for Data Analysis, 3rd Edition
Does polars have N-D labelled arrays, and if so can it perform computations on them quickly? I've been thinking of moving from pandas to xarray [0], but might consider poplars too if it has some of that functionality.

The Yougov poll is an interesting exercise in seeing how public perception does not align well with available data [0].

Section 3 of the link breaks down how many people have been identified as at risk from particular ideologies.

'Mixed, unstable or unclear' accounts for 51%.

Islamic extremism is 24%.

Right-wing extremism is 22%.

Left wing extremism is less than 3%.

So, the data aligns well with what the original commentator was suggesting.

ImageXav··on As professors struggle to recruit postdocs, calls for change in academia
Ah that makes sense. The rules have changed since, though a part time PhD would still take 6-7 years.

I imagine that must have been quite interesting!

ImageXav··on As professors struggle to recruit postdocs, calls for change in academia
Arethuza, I'm a bit confused by this comment. PhDs in the UK don't last over 4 years. Would you mind clarifying?

From a personal perspective I don't regret my PhD, though it was charity funded so it was topped up to be around £20 000 instead of the usual £14000ish per year. It was an opportunity to engage with a small group of experts in research that was engaging and of use to the wider world, and present it internationally. I also tried to start a start-up during this time, but the underlying idea failed to pass preliminary trials (I work in healthcare). So the two are not mutually exclusive.

People's experience tends to vary. I think a lot depends on how much you research the group and supervisors you will be working with beforehand, and how much you engage them in the research you do.

ImageXav··on Ask HN: Examples of good technical writing?
The book is "Improving almost anything - Ideas and essays" and can be found on Amazon, but I think the Wiley description [0] does it more justice. His writing is accessible and full of witticisms such as "When Murphy speaks, listen" (referring to Murphy or Sod's Law). His works are good building blocks for all kinds of research.

ImageXav··on Ask HN: Examples of good technical writing?
Code: The Hidden Language of Computer Hardware and Software by Charles Petzold is an excellent work that very clearly guides the reader through the components and steps that lead to the sophisticated computer systems we have nowadays. Each step is explained with no logical leaps and could be followed by a young child.

Improving almost anything by George Box blew my mind. As children and even as university students we have been lied to. We have been told that experiments must be carried out one at a time to assign effects. This is patently false. In fact, we miss out on potential interaction effects (think temperature and time in cooking) by using one factor at a time experimentation. In this book he discusses many now old but fundamental techniques by which large improvements in models can be gained with minimal data. It has helped me in my career immensely and made me aware of many usual methods and fields of study.

ImageXav··on Ask HN: What game do you wish existed?
Myths & Legends MMORPG

A replica of our planet, where you can play as either a hero or creature from ancient mythology. Your choice is limited by your location, so you can learn about the stories of cultures that previously inhabited your location.

Who or what you are affects the world around you, and players could join to expand their 'nation' into other countries, giving birth to new mythological creatures and heros based on how the cultures mix.

A giant but fun mythology lesson, effectively!
