I'm Director of IT at my company & I have been pushing us into going paperless wherever possible, I've mostly sold it as a money saving & green initiative, but the primary reason is I want to minimize the amount of time I or my team spend dealing with these infernal machines.

I like this rule of thumb for development with LLMs. I think there are things where I personally need to broaden this slightly (I know there is a problem in this Makefile, I know it's happening here, but I can't figure out the right Makefile syntax so let's ask Claude),but it's a good theory of mind

I think "lowering the activation energy" is a very good phrase to describe this feeling (I say as a physicist lol). I have overcome writing blocks just typing in single sentences and saying "I am thinking of a word to describe X thing, but it's not Y" instead of spending minutes with a thesaurus

A line graph titled "Emotions While Coding With Claude" plotting enthusiasm over a 15-minute timeline. The graph features a purple line that oscillates wildly and chaotically between two extreme states labeled on the Y-axis: the peak is labeled "Programming will change forever," and the trough is labeled "This is the stupidest machine I've ever interacted with." The visual illustrates a rapid, repetitive cycle of extreme optimism and frustration.

Anthropic made a very conscious decision to not do any kind of image or video generation unlike OpenAI and XAI, which 1. cuts off a potentially really ugly legal liability tail, 2. is much cheaper to train and serve, especially without video, and 3. makes the product far more enterprise-friendly.

he integration of Gemini into their larger toolchain seems to be hurting the perception amongst my colleagues and friends. Even my friends doing very significant scientific software development and getting benefit from tools like Claude hate Gemini integration in Gmail.

I had my computational astrophysics attach chat logs if they used AI and I have to say I got tremendous joy from a couple of them where at one point a student told GPT "this seems more complicated than what my professor was doing" and then GPT course corrected to giving more helpful advice

Honestly? Congratulations, your hardware *and* software are both working incredibly well and responding nearly instantly. All QA testing is a kick in the balls. (Tellingly, many people’s reaction to this is schadenfreude about AI, though this robotics demo likely has little to do with LLMs.)

Iβ€˜d be happier if I ran the world and the people who run the world seem like they’d be happier if they were mildly popular on social media, so perhaps we could work out some form of trade.

You might think that so many Millennials are lawyers because the Great Recession thrust a lot of young people into grad school but really it's because we got exposed to property law at a young age while dealing with counterparties reneging on the terms of a pre-negotiated Kadabra trade

Slain M.I.T. Professor Was a β€˜Brilliant Scientist’ and a Beloved Colleague

This is a nice write up. It's painful to read and continue to be reminded that he's gone, but the NYT talking to Steve and Alex and Ellen makes me feel like Nuno's life is being eulogized in a way that it deserves, commensurate with the profound positive impact he had www.nytimes.com/2025/12/20/u...

Definitely would have said Soma or Life is Strange in 2015, but I think one of the games I most think of now when I think about what games can be art-wise is Undertale. Helps Undertales ranking that its soundtrack, especially Megalomania, is still part of my work music rotation.

I want some goddamn accountability for my friend and colleague who is gone now because these dumbasses just want to cosplay running the FBI with aviator sunglasses and jackets. I can't even put into words the raw rage I feel that Nuno is gone because of these shitheads losing the shooter after Brown

My friend and colleague is dead because these dumbasses want to wear aviator sunglasses and an FBI jacket and I and the rest of my colleagues just have to live with the fact that Nuno is gone because the shooter was running around New England 48+ hours after Brown.

The self-congratulatory tone of this press conference is astonishing. Law enforcement misidentified the initial suspectβ€”againβ€”then allowed the actual perpetrator to be completely in the wind for 48 hours, during which time he went on to kill again

The other thing that doesn't help on the job market front is my friends and colleagues who are doing the faculty shuffle to get out of certain states. I've been fortunate enough to get a couple interviews, but have lost to folks I know who are already faculty and just trying to move

Until I get evidence to the contrary, I'm blaming Professor Nuno Loureiro's murder on the FBI incompetently failing to prevent an interstate killing spree

19.12.2025 04:13 β€” πŸ‘ 311    πŸ” 45    πŸ’¬ 2    πŸ“Œ 3

apparently the shooter may have shot himself in the storage facility after killing the MIT professor. im glad they eventually figured out his identity, but i can't help but feel that if the FBI was better at their job, they could have prevented the murder of this professor. there was a 2 day period
