reallymental··on AutoChain, lightweight and testable alternative to LangChain
LangChain is just too much, personal solutions are great, until you need to compare metrics or methodologies of prompt generation. Then the onus is on these n-parties who are sharing their resources to ensure that all of them used the same templates, they were generated the same way, with the only diff being the models these prompts were run on.

So maybe a simpler library like Microsoft's Guidance (https://github.com/microsoft/guidance)? It does this really well.

Also LangChain has a lot of integrations, that just pop up as soon as new API for anything LLM pops up, so that helps with new user onboarding as well.

reallymental··on Case study: Algorithmic trading with Go
Do count me in as well! Literally in the middle of building something like this myself.

I've also got a few questions regarding the way you manage memory, so I might ask you a couple !

reallymental··on Show HN: gpt-engineer – platform for devs to tinker with AI programming tools
Just a quick thing I loved about your gif at the end, the font and the theme of your Vim settings! Really loved it, do you mind sharing your .vimrc?
reallymental··on Native JSON Output from GPT-4
Is there any publicly available resource replicate your work? I would love to just find the right kind of "incantation" for the gpt-3.5-t or gpt-4 to output a meaningful story arc etc.

Any examples of your work would be greatly helpful as well!

reallymental··on Lessons Learned Reproducing a Deep Reinforcement Learning Paper (2018)
This feels exactly like the loop I'm stuck in right now, making me rely on sudden waves of motivation to complete such projects rather than curiosity driving me. Have you ever come out of this cycle before? I.e. Become more effective in planning a project so it doesn't lead one directly into a death-loop like above?

On a side-note, love your writing style, it's dry and sprinkled with the right amount of humour.

reallymental··on A GPT in 60 Lines of NumPy
Scope-dependent imports. What if a package is just required for that particular function, and once that function is done, the imported package is no longer required?
reallymental··on Jetnet Acquires ADS-B Exchange, a community-fed ADSB aggregator
Is there any service like this for AIS data?
reallymental··on Digging 10 miles underground could yield enough geothermal energy to power Earth
I, and the director of the movie "The Core", agree completely.
reallymental··on Funding Is All You Need: Getting into Grad School by Hacking the NSF GRFP
Umm not to be a wet blanket, but you're EXCEPTIONALLY well qualified.

I'm not downplaying your achievement, it's incredible that you've done everything that you have including getting the grant.

The only caveat being that you didn't have a network. I think that's what doing a masters programme is for... developing a network, that will lead you to an advisor and hence a "formal" PhD programme.

I don't have a PhD, but I would love to go back to school and get one. Been rejected 4 times now so I guess my time is running out or already has.

I love that options like this exist, in your searches have you found something for Canadian citizens/PR holders (I'm not a US citizen so this method won't work)?

reallymental··on Ask HN: Anyone Have Expertise in Trigonometry?
Considering that only one of those circles' radius is variable, and the other two circles intersect with the yellow loop, you can determine the equation of the yellow loop, which will give you the position of the white point, at any time, in constant time.
reallymental··on The Daily Wrong: AI-Generated Lies Every Day
This must be one of the best/most entertaining posts I've seen on HN.

Especially the bit about Gillette making razors for babies. Literally something that could become true in a parallel universe.

Incredible work!

Hi HN, I've been working on Data Science problems exclusively for the past 5 years, and gained a lot of supporting knowledge related to ML infrastructure during this time.

I'm most proficient in GIS and financial time-series datasets, like locations of shipping vessels/flight tracking/road traffic tracking as I've spent the most time with trading houses correlating paper contract prices to the movement of these physical assets.

I've got 7-8 years of experience with Python in general, and I'm really proficient with PostgreSQL (for any back-end task) and establishing pipelines for Machine Learning (ML) tasks (using Prefect for the past year or so).

I also work on data science problems exclusively, without the adjoining back-end problems (e.g just give me the data set and you'll get back a model).

Over the past 3 years, I've also become quite proficient in Golang and if you have some projects in Golang, I'd like to work on them as well.

reallymental··on Show HN: Bhagavad Gita Android App for searching verses by topics like anxiety
Wow it's safely been a decade and a half since I've even thought about these episodes! Thanks for bringing it's memory back to life.

On a slightly different note, these episodes (essentially, plays) didn't capture some of the spirit that the book shares. The book is more sombre in my opinion, it informs the reader of the things that happened (albeit in a Hardcode history - like manner, very fantastical and poetic), and it doesn't offer any pre or post-amble. A drive-by epic, if you'd like.

reallymental··on I found my Grandpa’s notes 20 years after he died (2020)
An alternative comment:

I've found people's handwriting deteriorate as time has gone by... cursive is rarer to come by (leaving the 'legibility' argument aside), typing has certainly contributed to this, but some people still write on boards to explore ideas and boy are those diagrams and writings unreadable.

If the author posted some samples of the grandfather's notes (withholding personal information), that would have added a very personal touch to the article indeed, and also ensured his ancestor's work gets recorded by archive.com.

edit: grammar.

reallymental··on Twitter is blocking tweets that criticize the Indian government
Yeah I think "democracy" means the exact opposite of what you've said there. The people have asked for free speech, not censorship.

And dragging the British East India Company into every argument about India sheds more light into the inadequacy of us Indians to move past it. We're supposed to be healing ourselves by constructively criticizing our behavior towards others and ourselves...not by endlessly blaming the past for our current actions.

Disclaimer: I am Indian.

reallymental··on Indian Government Breached, Massive Amount of Critical Vulnerabilities
Is there any financial incentive to secure an Indian citizen's data ?

In fact, there's more financial incentive to make things leaky, less work needs to be done to peek into your neighbors yard, and the vast (vast, vast) majority of the people cannot give a damn about this.

Frankly, I'm surprised they replied with an acknowledgement and tried to fix some vulns.

Expect no more changes.

reallymental··on Reddit and Robinhood gamified the stock market, and it’s going to end badly
I think the comparison to 1928, and 2021 may be incorrect.

If we were to assume they're both very similar, there would have been a bailout of banks around 1916 leading to QE and the rise in tide after. There was even a pandemic + war around 1918, so a crash should have occurred around then. And the "fundamental" drivers seemed to have been people buying stocks on credit (now margin) and the easy availability of credit. I don't really see the easy availability of credit now, except for the stimulus checks, and they're a write-off, not a liability for the gov.

If anything, we're in for another roaring 20's. But we must all buy raincoats in these 20's as we know what came after.

I'm not a historian, nor am I right about many things, so please correct me if I'm wrong.

reallymental··on Show HN: A high-performance TensorFlow library for quantitative finance
I understand that this is google's library, and they're promoting TensorFlow's usage, and subsequently the usage of TPU's.

But this can just as easily be done in Pytorch right? Yes we can't have GPU's there but having your model train 50% slower (exaggeration) is better than having to spend 150% of the time taken in Pytorch to debug anything in TensorFlow.

I may be beating a dead horse here, but why doesn't google just accept that TensorFlow needs to be redesigned for more ease of use?

Can anyone point out the benefits of TensorFlow over Pytorch (besides TPU's) ? It's been a few years since I've used TF and I may have missed something.

reallymental··on Traffic Simulator
Perhaps these questions are appropriate for this post.

I'm beginning to delve into this space and I've not managed to get any satisfactory answers to these questions, despite my month(s) long search.

1) How does one build a traffic (i.e state-space system), forgetting the visualization aspect of things ? Just generating sparse matrices, and adding elements to interact (add/subtract) from these matrices would be a great start! Any way to do this in a compiled language ?

2) Are there any libraries out there that help you simulate traffic in an existing network of roads, extracted from OpenStreetMaps perhaps?

reallymental··on New Reddit’s PageSpeed Insights
- Avoid an excessive DOM size: 1658 elements.

That's insane.

reallymental··on VR health appointments can help patients address eating disorders
CBT (Cognitive behavioral therapy) is a flavor of what you're describing.

It's very effective if administered properly, and regularly, just like "working out your brain".

I did read the article, in the hopes that VR might actually bring something to the table.

I did find the "collaborative playful activity to improve patient-therapist relationship" part quite condescending (to both patient and doctor). Are none of them capable of having a conversation and reach a middle ground from where they can communicate effectively?

Is this VR solution for cases that severe?

I didn't find answers to the questions above.

But CBT works, to an extent. This (Virtual Reality Exposure Therapy (VRET)) might work too, but the article needs to tone down the condescension.

reallymental··on California Is in Trouble – 340k Public Employees with $100k Paychecks
Through just a cursory reading of who's getting P-P-P-PAID,

- 109,627 teachers and school administrators.

- 66,403 college and university employees.

- 62,204 State of California employees – including a nurse.

- 45,718 city and town employees: including 1,420 municipal administrators and employees who out-earned the California governor – the highest paid state governor ($202,000).

Notably we have teachers, college and uni employees (not sure of the % of admin vs educators here), and state employees (not sure of the admin vs essential workers here as well, whatever the definition of essential)

And they name-and-shame some of these employees as well.

What's the matter here? Bloated admin costing money? or competition costing money? The article attributes it to both.

So why shouldn't the gov. workers get paid? Singapore does that (but they actually have a functional gov.).

But paying gov/school/college workers well has got to be a good thing! Incentivizing them/others to strive to do a better job/game whatever metric to get that job, which cannot be entirely corrupt.

There's a nurse in there well.

California does not seem to be in trouble because of these people who are highly paid.

California is grasping to find a patsy to blame.

reallymental··on Almost Realtime Live Data Visualization in QGIS – Air Traffic Use Case
Finished a project very analogous to this, with marine vessel traffic data (AIS mostly).

It's fun to visualize these patterns, but the business case soon ran out. People don't really care about absolute numbers. Diff is what matters the most.

Most of the analysis is "OK, how does this value compare with one week ago". Can't really do that in QGIS/ArcGIS... no matter how pretty the visualization.

In the end, time series always emerges victorious in capturing the right information/visualization ratio.

reallymental··on Usbkill – anti-forensic tool to halt computer when new USB device is connected
"Tip: Additionally, you may use a cord to attach a USB key to your wrist. Then insert the key into your computer and start usbkill."

This line particularly caught my eye. I wonder what's the percentage of people (I'm presuming people working in security or those who are trying to avoid detection) go to this extreme?

Is is even extreme?
