complex_pi··on Software Engineering fundamentals matter more
Maybe it looks like reasoning, and maybe that's enough for some.
complex_pi··on The deadly rise of giant trucks and SUVs
Where I live (western EU) it's simple. If the speed is limited to 25 km/h it's an e-bike. Above it's a speed pedelec and requires registration plate + insurance.
complex_pi··on French physicist and media star loses doctorate after plagiarism investigation
Academia is very broken. That's it actually.

It's a long time that the incentive and job structure make universities a very toxic environment. Professors are basically running a 40 years race (about from bachelor or master graduation to retirement). It is still amazing that some good comes out of it.

complex_pi··on AI Made Writing Code Easier. It Made Being an Engineer Harder
I played the blog post game (using chatgpt).

Prompt: "The text of the blog article is copy-pasted below. Please summarize it in one parargaph."

Result: "The blog article explores the paradox that while AI has made coding easier by automating many tasks, it has also made the role of software engineers significantly harder. AI tools have raised expectations for productivity, leading to increased workloads and burnout without corresponding support or recognition. Engineers, especially juniors, are now expected to take on broader responsibilities—ranging from product thinking to deployment—while the hands-on act of writing code has diminished. This shift in roles and expectations is often unacknowledged by leadership, creating a disconnect between those who use AI tools and those who manage the work. The article emphasizes the growing complexity of the engineer's job, the burnout that results from unrealistic demands, and the identity crisis many engineers face as their core role changes. It calls for better leadership, structured training, and realistic expectations to avoid the erosion of trust and talent in the industry."

Whatever. Blog posts about AI that dance around the topic are not that valuable. For a project, you'll hire somebody, not some AI (as bcachefs' author does). What matters is that you trust a person to do the job, and expecting them to churn code is useless. The real benefits of someone appear on their CV (experience, known technologies, human abilities -- communication, empathy, understanding).

AI generated content is an existential threat to human knowledge.

complex_pi··on Europe’s next-generation weather satellite sends back first images
EUMETSAT publishes data as CC-BY 4.0 past a timeliness of 1 hour https://www.eumetsat.int/data-policy/eumetsat-data-policy.pd...

Look for your dataset here https://data.eumetsat.int/ (Note: you need registration but it is free).

complex_pi··on Contrails Map
It's not specifically about logic. It is possible to model and measure the radiative effect of contrails.
complex_pi··on Over-regulation is doubling the cost
The EU also has regulations, but somehow it does not make insulin as expensive as in the US. Maybe the existence of a regulation is not the issue here.
complex_pi··on Armed police handcuff teen after AI mistakes chip bag for gun in Baltimore
Agree on that (that AI should not be in the loop and that humans are ultimately to blame).
complex_pi··on Armed police handcuff teen after AI mistakes chip bag for gun in Baltimore
The end result is the same to be honest.
complex_pi··on The collapse of the econ PhD job market
Welcome to the world. A PhD guarantees nothing, tenured position barely exist anymore. Weird that economists did not realize this yet...

complex_pi··on Europe's first geostationary sounder satellite is launched
NOAA/NASA (USA), EUMETSAT (European organization), JMA (Japan), KMA (Korea), and CMA (China) all have a geostationary satellite (one or more actually). So, northern hemisphere countries, but the coverage is global thanks to the fact that you need to be, as you say, above the equator.
complex_pi··on Europe's first geostationary sounder satellite is launched
In meteorology, you also have ecmwf.int (the European Center for Medium-Range Weather Forecasts).
complex_pi··on Europe's first geostationary sounder satellite is launched
If the question is about satellite vs ground instrument: the geographic coverage from the satellite is much greater. Geostationary instruments over Europe cover the Atlantic Ocean, Europe, Africa, the Middle East.

If that was not the question, can you provide more detail?

complex_pi··on I Don't Like NumPy
NumPy allowed a PEP for the in-memory representation of arrays in Python. This is tremendous useful for making APIs.
complex_pi··on I don't like NumPy
NumPy allows a lot of science to happen. Grievance is fine but a little respect is as well.

NumPy is the lingua franca for storing and passing arrays in memory in Python.

Thank you NumPy!

complex_pi··on Why does storing 2FA codes in your password manager make sense?
A file-based password manager ils something you have (the file) and something you know (the master password) provided you have a timeout on the password manager and a safe screensaver. (In reply to some comments below).

It does require some thought / hygiene but seems a fair compromise.

complex_pi··on I prefer rST to Markdown
I can't test (no computer right now) but can't include directives achieve what you want?
complex_pi··on The Puzzle of How Large-Scale Order Emerges in Complex Systems
The author of the article, Philip Ball, wrote an excellent book on order almost 20 years ago: Critical Mass https://philipball.co.uk/critical-mass-how-one-thing-leads-t... He also wrote many other interesting books but "Critical Mass" really reviews a lot concerning emerging phenomena in complex systems from the point of view of a condensed matter physicist.
complex_pi··on Tmux is worse-is-better
As tmux is discussed: my setup is xterm + tmux with 'C-o' as the key binding. Conflicts with nothing I use and allows me to start screen while in tmux (don't ask :-O but sometimes tmux is local and I want a remote screen). The binding is also ok whether you use vi or emacs. What else could you want?
complex_pi··on Most of Europe is glowing pink under the aurora
I stayed up until about 1AM only. Views from the mountains are hard to match in any case 8-)
complex_pi··on Most of Europe is glowing pink under the aurora
Well visible in Belgium starting around 23:30 ! Even with the naked eye ! (From outside the city)
complex_pi··on Linux being secure is a common misconception
The macs I support in my private circle run very well without an antivirus. It is anecdata of course but about 15 years of it for several "lambda" users.
complex_pi··on Fortran 2023
Besides the technical part, Fortran's community has evolved a lot as well since 5-10 years. See the community paper here: https://arxiv.org/abs/2203.15110 "The state of Fortran" (not an author myself)
complex_pi··on Governments turn to Open Source for sovereignty
The EU has their own mastodon instance at least. Only for official accounts but it means they are part of the federated network
complex_pi··on macOS Sonoma Broke Grep
To all who suggest nix or docker or whatever. Please consider that it should not be necessary in the first place. 20 years ago Apple advertised its laptops as "real Unix on your laptop" which rightly appealed to a lot of scientists

It is fair from the user to expect some stability here.

complex_pi··on Things Every Hacker Once Knew (2017)
Firefox supported FTP until a few months ago. Not sure which version though, but it is fresh in memory: I had some such URLs in my history that couldn't be displayed anymore
complex_pi··on I wouldn't be productive enough for today's academic system (2013)
The current academic system produces (in small quantity of course) interesting science by chance and not by design. Local funding agencies only reward what's fashionable and are (mostly ) unable to fund anything new

Pursuing in academia is not smart at the individual lebel, that indeed expels a lot of talented individuals.

complex_pi··on LibreOffice 24.2 Will Succeed LibreOffice 7.6
Primary office program since a decade or so. I don't own MS Office and for many purpose it is quite convenient to have/be able to use files on disk (admin forms, attachments and downloads, etc). I use cloud tools when needed but I am very happy with LibreOffice otherwise.
