rjurney··on The moral panic over data centres is foolish
Local outrage over construction is the only protest people have against their wholesale replacement at work. They're totally fucked, and you know it. And you aren't. Have empathy.
rjurney··on Paul Atkins misreads Adam Smith and the American founding
This was number one, I wish it still was. The founders railed against precisely the kind of aristocratic, authoritarian corruption this administration represents.
rjurney··on New Orleans is testing Carbyne’s AI-powered Emergency Call Triage software
It is this or wait on hold forever... triage it should be able to handle.
rjurney··on Discontinuation and reinitiation of dual-labeled GLP-1 receptor agonists
So try Mounjaro. It works better.
rjurney··on I think nobody wants AI in Firefox, Mozilla
I've tried the Perplexity browser and... I can't figure out what it does or how it is better?
rjurney··on Kafka is Fast – I'll use Postgres
One bad message in a Kafka queue and guess what? The entire queue is down because it kills your workers over and over. To fix it? You have to resize the queue to zero, which means losing requests. This KILLS me. Jay Kreps says there is no reason it can't be fixed, but it never had been and this infuriates me because it happens so often :)
rjurney··on Ask HN: I made a new kind of AI, how do I make money from it?
You need a sales / product cofounder to be CEO. Create a compelling demo of it doing amazing things, then put all your energy into finding a cofounder. Startups are a team sport and you need help with customer development.
rjurney··on Altered states of consciousness induced by breathwork accompanied by music
This is not a surprise to anyone that has engaged in prolonged meditation, especially across more than one day. It makes shortcuts like psychedelics look foolish. During a ten day Vipassana retreat time slowed down to such a great extent it changed my entire perception of time thereafter. The space provided by the mental quiet created by Anapana is so profound.

TLDR Anapana: Sit comfortably and monitor the sensation of the breath exiting the nose and return to it as your thoughts wander. Don't get mad when you wander, it's part of the process. Just return and try to maintain equanimity, to not react. If you get frustrated at first, you can increase your exhale slighlty to make it more noticeable.

That's about all there is to it. After you do this for a while your thoughts become less and less frequent and... you only have important, creative thoughts :) It turns out conscious thought is just a refection of a deeper process and most of it is garbage: worries, self doubt, fears.

I have just inspired myself to take up daily Anapana by writing this...

rjurney··on The ‘white-collar bloodbath’ is all part of the AI hype machine
Workers in denial are like lemmings, headed for the cliff... not putting myself above that. A moderate view indicates great disruption before new jobs replace the current round being lost.
rjurney··on I let Claude Code write an entire book
As a writer, this is deeply comforting. The book is total shit. It sounds like an AI, not like something a person would connect with for even a moment. Not even in the opening lines.
rjurney··on Ask HN: What will tech employment look like in 10 years?
When AI is cheap, why use juniors, regular software engineers or off-shore labor at all? AI replaces these things. Why not use the best available talent to oversee and guarantee the work of coding agents? To define requirements and translate them into maintainable code? This is the trend. It takes mastery to produce good, maintainable code from vague requirements using coding agents. This seems like value add a human will continue to provide.

I also see the blending of engineers and data scientists with product managers.

Yes, you rarely hear specifics like this as to where new jobs will come from. Hear, hear!
rjurney··on Gemini 2.5 Flash
I am building a knowledge graph using BAML [baml-py] to extract documents [it's opinionated towards docs] and then PySpark to ETL the data into a node / edge list. GPT4o got few relations... Gemini 2.5 got so many it was nuts, all accurate but not all from the article! I had to reign it in and instruct it not to build so vast a graph. Really cool, it knows a LOT about semiconductors :)
rjurney··on Pico.sh – SSH powered services for developers
I don't really mean you, but let's say you are compromised... if I put a localhost http server up on the web using your stuff, am I now compromised? Not clear how this would work...
rjurney··on Pico.sh – SSH powered services for developers
This thing is really cool, I want to pipe data between systems... can I trust you to have that kind of access?
rjurney··on US appeals court rules AI generated art cannot be copyrighted
Well... that's one solution the the problem.
rjurney··on GIMP 3.0
There isn't one for those three apps.
rjurney··on GIMP 3.0
I'm really tired of shelling out $90/month for Photoshop, Illustrator and Acrobat...
rjurney··on Mistral OCR
What about tables in PDFs?
rjurney··on Seeing Through the Spartan Mirage
Sparta buried her war dead on the field in mass graves. A hoplon shield isn't useful to carry a body in the first place. This is the first I've heard that attributed to Plutarch, however...
rjurney··on You're not a senior engineer until you've worked on a legacy project (2023)
You're not a... engineer, engineer if you haven't worked on a legacy project. You're a junior engineer. Title inflation.
rjurney··on Fluoxetine promotes metabolic defenses to protect from sepsis-induced lethality
Usually they fuck with something like extra sweating or a little trouble sleeping. Severe side effects are very rare, they are widely used because they are so well tolerated. My own anecdote is: most elderly people should be on Cymbalta because they live in so much pain. I've been offered Prozac for chronic pain, I bet it would help them too. Boomers suffer needlessly. Get them on Prozac, please.
rjurney··on Fluoxetine promotes metabolic defenses to protect from sepsis-induced lethality
I just object to the use of anecdotes on the internet from actual doctors.
rjurney··on Building a personal, private AI computer on a budget
Okay, wow I've never heard of one of those!
rjurney··on Fluoxetine promotes metabolic defenses to protect from sepsis-induced lethality
His comment isn't a medical opinion. It's a sarcastic anecdote.
rjurney··on Fluoxetine promotes metabolic defenses to protect from sepsis-induced lethality
Sorry, what does this have to do with the study? Obviously reuptake inhibitors save many lives and you're acting like they're all unusable. As a doctor, isn't this irresponsible?
rjurney··on Fluoxetine promotes metabolic defenses to protect from sepsis-induced lethality
This is beautiful. So many boomers have severe chronic pain and depression... get them on Prozac and address these issues while protecting them from Covid-19 related complications.
rjurney··on Building a personal, private AI computer on a budget
A lot of people build personal deep learning machines. The economics and convenience can definitely work out... I am confused however by "dummy GPU" - I searched for "dummy" for an explanation but didn't find one. Modern motherboards all include an integrated video card, so I'm not sure what this would be for?

My personal DL machine has a 24 core CPU, 128GB RAM and 2 x 3060 GPUs and 2 x 2TB NVMe drives in a RAID 1 array. I <3 it.

rjurney··on Ingesting PDFs and why Gemini 2.0 changes everything
I've been using NotebookLM powered by Gemini 2.0 for three projects and it is _really powerful_ for comprehending large corpuses you can't possibly read and thinking informed by all your sources. It has solid Q&A. When you ask a question or get a summary you like [which often happens] you can save it as a new note, putting it into the corpus for analysis. In this way your conclusions snowball. Yes, this experience actually happens and it is beautiful.

I've tried Adobe Acrobat AI for this and it doesn't work yet. NotebookLM is it. The grounding is the reason it works - you can easily click on anything and it will take you to the source to verify it. My only gripe is that the visual display of the source material is _dogshit ugly_, like exceptionally so. Big blog pink background letters in lines of 24 characters! :) It has trouble displaying PDF columns, but at least it parses them. The ugly will change I'm sure :)

My projects are setup to let me bridge the gaps between the various sources and synthesize something more. It helps to have a goal and organize your sources around that. If you aren't focused, it gets confused. You lay the groundwork in sources and it helps you reason. It works so well I feel _tender_ towards it :) Survey papers provide background then you add specific sources in your area of focus. You can write a profile for how you would like NotebookLM to think - which REALLY helps out.

They are:

* The Stratigrapher - A Lovecraftian short story about the world's first city. All of Seton Lloyd/Faud Safar's work on Eridu. Various sources on Sumerian culture and religion All of Lovecraft's work and letters. Various sources about opium Some articles about nonlinear geometries

* FPGA Accelerated Graph Analytics An introduction to Verilog Papers on FPGAs and graph analytics Papers on Apache Spark architecture Papers on GraphFrames and a related rant I created about it and graph DBs A source on Spark-RAPIDS Papers on subgraph matching, graphlets, network motifs Papers on random graph models

* Graph machine learning notebook without a specific goal, which has been less successful. It helps to have a goal for the project. It got confused by how broad my sources were.

I would LOVE to share my projects with you all, but you can only share within a Google Workspaces domain. It will be AWESOME when they open this thing up :)
