Just realizing how little I use social media to promote my work, so let me take a little time to talk about fmdtools.
Basically, fmdtools is a Python library for performing research into complex systems #resilience, focusing heavily on modeling and simulation.

my issue with the hand wringing is that you've already lost it, this is the culture writ large, we're all just trying to cope that years of putting off dev of internal talent and process outside of orgs like GOOG has basically condemned us to a landscape where the baseline is de-facto vibe coding

VTA's inability to prevent or quickly end the strike is embarrassing and reflects really poorly on how much they value the public being able to rely on their system.
As the region is facing a tepid ridership recovery, it makes no sense to set roadblocks in front of transit use

Reminder: No bus or light rail service until further notice. We know how much our community depends on transit, and we’re working hard to resolve the labor dispute. For more information visit our website vta.org. Riders check Transit App for alternative transportation options.

It also kind of relies on the idea that scientists are inherently mobile and cosmopolitan enough to pick up and leave their families on the drop of a hat
Pet peeve: I hate how often ppl claim “all the researchers will just move to Europe/Canada!” You vastly under-estimate how little money there is there vs the USA- and unless that changes ASAP this loss is just going to decimate global science, full stop. 🧪🔭

I review 20+ of papers a year—it's my job as a scientist. The public pays my salary and trust me to use my time wisely to advance science. Through peer review, I do exactly that. I spend two or three weeks a year reviewing, but I’ve never wasted a day reviewing a paper, and never will.

Reading through the lines, it sounds like a lot of the team might set up a contract shop where they can charge the government (and private enterprise) much more money for the same stuff they were delivering in-house.

The whole paper is an absolute nightmare funfair ride through the behaviours that have become almost instantaneously widespread through the professional world - something Microsoft have invested billions into accelerating and worsening no matter the consequences.
![Integrate partial response (36/319). GenAI excels at generating
large amounts of information that appear relevant, and not all of it is
useful. Participants viewed the process of selectively incorporating
the relevant parts of GenAI output into their tasks as critical thinking. For example, when P188 used ChatGPT to help her summarise
her past work as an auditor for her resume: “some of the information
provided did not particularly relate to my role and even to the country
I was working in. So rather than copying over everything, I had to
critically evaluate what would apply, the regulations mentioned - do
they apply to the country I work in.”
Modify style to be appropriate for the task (45/319). Finally, participants reflected not only on what to incorporate from the response,
but also how to incorporate it. They might add a “personal touch”,
or adjust the tone to align the response with their intended style.
For example, when P210 used ChatGPT to revise his paper abstract,
he had to rephrase the output with a scientific tone because “often
the AI writes awful stuff like “our groundbreaking and fundamental
analysis shows...” that sounds too emphatic and does not fit the scientific style.” Participants also attempted to make the GenAI output
read less “AI-generated” and more personal, as P254 noted: “I did
make sure it [email composed by ChatGPT] read properly and made
sense and did sound like an email that I had composed myself and
that a colleague would send.”](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:66lbtw2porscqpmair6mir37/bafkreif5dnepr47saibv35elavhgduji6omakx6n423tswq62cbwbdrhx4@jpeg)
![Complementing our quantitative findings, knowledge workers’
trust and reliance on GenAI (83/319) doing the task can discourage them from critically reflecting on their use of the tools. Users
often adopt a mental model that assumes AI is competent for simple
tasks. This was influenced by users’ prior experience with GenAI
tools, where the AI had proven trustworthy for specific tasks, as
P289 noted: “With straightforward factual information, ChatGPT
usually gives good answers.” For instance, P275 remarked: “It’s a
simple task [make a passage professional] and I knew ChatGPT could
do it without difficulty, so I just never thought about it, as critical
thinking didn’t feel relevant.” This mental model, however, can lead
to overestimating AI capabilities. Some users, like P185, believed
the information provided by GenAI tools was always truthful and
of high quality, while others (e.g., P143, P236) assumed the outputs
would consistently and accurately reflect referenced data sources.
Complementary to the perception of AI as being competent and
capable, some participants expressed self-doubt in their ability to
perform tasks independently, such as verifying grammar in text](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:66lbtw2porscqpmair6mir37/bafkreibvgjnpudfgl7nvl6l2zt2ywi44tk4x6mnyz32c6skkkrz2ute5nu@jpeg)
