algo_trader··on Has the Autonomous Trucking Revolution Arrived?
> Source: I make software for trucking carriers and drivers

Is there a rough estimate of how many miles are mostly hub-to-hub and (can) by-pass urban zones?

> keeping just 50 trucks charged annually uses as much electricity as a decent sized town

My analysis is <150KW PV per tractor. So 7MW is very C&I scale. Scheduling can be tricky.

> having that same truck get to a warehouse in the center of Dallas is a nightmare even for pro drivers

This is the L5 fallacy. We will get commercial viability way before L5.

algo_trader··on Upgrade your desktop: Ubuntu 26.04.1 LTS is now available
Is there a good combo that works with spotify web?
algo_trader··on Hitachi to double US production of small and medium-sized power transformers
What's the top V these cretins will reach? Can they reach 10-20kV? Can they be "stacked" ?

IIUC the real bottleneck is in transmission (>50kv) not distribution transformers.

algo_trader··on Aptera announces a $44M to design and build a solar electric vehicle
warning: total manufacturing newbie here

But i would like to ask.

How much effort/legal/heartache is involved in building an after market add-on for commercial vehicles?

Some comforting assumptions - internal customers. no sales. - good software talent. can work around anything. - almost no moving parts - mostly electronics - can accept cost overrun on the components - each unit is >$10K - gradual scaling to 1000s units/annum - daily return to hubs if needed

algo_trader··on Small Models Have Arrived
> VibeThinker 3B constitutes extraordinary evidence.. math and logical reasoning

Any similar model aimed at coding?

A >10B model for mass spawning/swarming and reporting back to a larger model

algo_trader··on Qwen3.8 27B scores 52 on Artificial Analysis
> So, I'd say it's a tie in practice, both are awesome :)

Which harness for the benchmark ?

You have previously commented on using OC/GLM. R u going to stock with it?

algo_trader··on Qwen3.8 27B scores 52 on Artificial Analysis
> I used Qwen 3.6 27B extensively (>1B tokens) and DeepSeek V4 Flash

Were your opinions effected by the harness ?

DS is an amazing combo. It probably could only happen in China, not in current USA or EU (for different reasons)

algo_trader··on DeepMind's WeatherNext model achieves breakthrough forecasting cyclones
I am getting into cyclone predictions (for maritime scheduling)

Is there a basic/freemium resource for past events? Mostly just very coarse spatial/temporal maps of past events

this is a common meme [1]

algo_trader··on Sakana AI's Recursive Self-Improvement (RSI) Lab
Do you actually understand why evolution methods are beneficial?

SGD generates a stronger learning signal,is more efficient, and scales better. Using it end-to-end makes it stronger yet.

Yet somehow mixing in a weaker blunt evolution stage improves the result?

algo_trader··on Show HN: Solving complex optimization problems with Google OR-Tools in browser
this is nice

can the browser connect to a server to offload heavier calculations?

algo_trader··on Largest electric autonomous container ship begins commercial service
Standard LFP cells - with higher QA and optimized for safety over performance

The pack/container is (over?) designed for fire suppression and humidity control

CATL and also CALB have specific marine-grade product lines

At sea - even at full power - the packs discharge relatively slow

algo_trader··on A Dumb Introduction to Z3 (2025)
What would u recommend for freight/trucking optimiser? not real time.

(scaling to 100s-1000s of units)

algo_trader··on Electrical transformer manufacturing is throttling the electrified future
> practical voltage for a DC grid using early electrical machinery is around 2 kV.

What is a current (pun!) practical limit?

If a 100MW PV farm and a data center are separated by 1km (20 Olympic pools) - is there a way to avoid AC?

I know there are future solutions [1]

algo_trader··on Spain shuts airspace for US planes involved in Iran war
> Israel has both universal healthcare and tuition free university

This is both wrong and off topic.

Israel health care is funded by a 5% additional income tax tier. non working people pay a significant fixed annual fee.

University is not free. $5K for the public institutions - which have limited admissions. $10K for many of the spill over private institutions.

Now - about those space lasers ....

algo_trader··on [dead]
> $85k and closed our account

This seems excessive. Unfortunately OP does state how many disputes they had.

Why would an operator now withdraw the monthly/weekly cash balance?

algo_trader··on MacBook M5 Pro and Qwen3.5 = Local AI Security System
> fully local home security system

R u running the GPU at full throttle 24x7? Have you encounters silicon failures over time?

algo_trader··on Show HN: Playing LongTurn FreeCiv with Friends
> for longturn games (23-hour turns)

Why 23 hours? Is this a typo?

algo_trader··on Tree Search Distillation for Language Models Using PPO
great write up (and effort!! ;))

what are your thoughts on MCTS for coding?

this can/must be paired with a smart execution harness to optimise roll out and roll back of execution paths and system state.

does this change the calculus for optimal post-training ?

algo_trader··on Tesla 'Robotaxi' adds 5 more crashes in Austin in a month – 4x worse than humans
Was Karpathy "fired" from Tesla because he could not make camera only work ?

Or did he "resign" since Elon insists on camera-only and Karpathy says i cant do it?

algo_trader··on MiniMax M2.5 released: 80.2% in SWE-bench Verified
> MiniMax first in my AI workflows, GLM for code tasks and Kimi K2.5

Its good to have these models to keep the frontier labs honest! Can i ask if you use the API or a monthly plan? Do the monthly plan throttle/reset ?

edit: i agree that MM2.1 most economic, and K2.5 generally the strongest

algo_trader··on Ask HN: What are you working on? (February 2026)
I have a spring/react jar.

Previously I built a jar/docker and deployed to a common server. Fine.

Can this service deploy this to AWS free tier? Will it "know" how to avoid any paid services? (I don't necessarily need a docker or even permanent storage yet)

EDIT: Also - charging a % of AWS bill is pretty wild...

algo_trader··on Instabridge has acquired Nova Launcher
The irony, Mrs Morissette, is that Nova caused the battery to appear to fail, and would drain the battery still on a new phone
algo_trader··on Instabridge has acquired Nova Launcher
> my battery is no longer draining for no apparent reason

Oh man. I just replaced the battery on my 5 year phone - for the sole reason of not having to reconfigure Nova on a new phone :\

algo_trader··on Show HN: Play poker with LLMs, or watch them play against each other
there plenty of published preflop charts and GTO ranges

in fact, a fun project would be take a non-reasoning model, play on a lesser known game format, and see if it learns an "a ha" moment or explicitly simulate moves ahead

algo_trader··on Notebook Lawyer
Do you still get deals from angellist (your angel.co link now leads the HR Site)?

The angellist site itself seems to hide the startup/pitch side

algo_trader··on Ÿnsect, a French insect farming startup, has been been placed into liquidation
> food waste from various stores brought to a facility to be fed to insects

a. how does that solve the transmission problem?

b. amazing work by EU bureaucrats to regulate businesses that dont exist yet

c. they can export the feed to fish farms or china or whatever. the question is do the economics work. US soy bean is just incredibly productive (and subsidized)

algo_trader··on Scaffolding to Superhuman: How Curriculum Learning Solved 2048 and Tetris
This is less about masked modelling and more about reverse-curriculum.

e.g. DeepCubeA 2019 (!) paper to solve Rubik cube.

Start with solved state and teach the network successively harder states. This is so "obvious" and "unhelpful in real domains" that perhaps they havent heard of this paper.

algo_trader··on Meta's ads tools started switching out top-performing ads with AI-generated ones
can you spare 5 minutes for a quick email/chat about bidding/campaigns?

its rare to find a technically proficient media buyer ;/

(I am not a FB employee or a lawyer.. ) I will send you a DM on twitter

algo_trader··on Analysis finds anytime electricity from solar available as battery costs plummet
The original report by Ember [1] is decent but clearly biased.

They assume each battery cycles entirely EVERY day - even in winter. They also assume PV is never curtailed - not even in summer. They of course ignore multi-day weather anomalies. Like wise for weekend/holiday demand variations. etc.

The best part of the report are real world bids of 2025 ESS projects.
