Agents should get better with experience. We teamed up with @tolokaAI to measure that.
Toloka evaluated xmemory on closed datasets. No peeking at the data. No tuning to the benchmark. Just learning from failures and measuring what improves.
📈 The results: 26% lower token costs when xmemory replaced document search as the policy store. And adding lessons from past runs lifted scores by 4.8 percentage points on held-out tasks.
💡 It means with memory, a mid-size open-weight model scored 0.75 – beating Sonnet 5 at 0.68 and GPT-5.6 Terra at 0.69 without memory.
This experiment is just the beginning of what memory can unlock. We see even bigger gains on longer-horizon tasks, where every lesson has more chances to pay off.

This is what entrepreneurialism feels like. xitter.cf/tannokasa9/status/2079…

The UK has a far flatter income distribution than the Communist Soviet Union.
The UK take home minimum wage for working a full time job (40-hours) is now £22,555.
At £100k salary, the take home is £68,558.
That is a net income ratio of 3.04:1
We are now at the point where the wage compression and taxes in the UK means that the difference between minimum wage and a top 5% salary is a net income difference of only ~3x.
In the USSR using the same comparison, this figure never fell below 5:1
It's actually even worse in reality because the person earning £100k in the UK often has student loans.
Britain is nominally capitalist but functionally communist. China is nominally communist but functionally capitalist.
Funny how that works.

Time for the next post - this time focused on Desktop UI Agents:

Today we’re sharing our first blog post: “Schema as the Core of Reliability.”
Our view is simple:
AI memory breaks down when facts are stored as unstructured text and reconstructed later. That approach can work for thematic recall, but it becomes fragile when systems need to answer exact questions, maintain state, support workflows, and drive automation.
In the piece, we explore why:
- Search can recover context, but memory must support facts
- Graph RAG is a meaningful step forward, but not the endpoint
- Reliable memory needs structure - types, relations, constraints, deduplication, provenance
- Schema is not decoration - it is the contract that makes memory observable, enforceable, and dependable
If AI systems are going to do more than sound coherent - if they are going to make decisions, trigger workflows, and operate over long horizons - memory has to become a governed system of facts.
That is where reliability starts.

Citadel Securities published this graph showing a strange phenomenon.
Job postings for software engineers are actually seeing a massive spike.
Classic example of the Jevons paradox. When AI makes coding cheaper, companies actually may need a lot more software engineers, not fewer.
When software is cheaper to build, companies naturally want to build a lot more of it. Businesses are now putting software into industries and tools where it was simply too expensive before.

I can’t believe I only just now found out about this four years late while trawling through settings, but windows terminal has (literally!) “Quake Mode”, where win+backtick/tilde opens/closes a terminal at the top of your screen.

It's probably hard for Americans to imagine this because it's their normal
But being European and living in Europe and being radically honest when I arrive in America the main feeling I get is just endless abundance
Non-honest (I'd say many to most) Europeans will not be able to deal with this abundance and start coping "zOmG but if you hit your knee you will go bankrupt cause healthcare bills" and "look at the homeless tents" and "lol look at the Amerifats!!!"
Even if fully true, that's kinda besides the point, the range of America is much wider, the bottoms are lower and the peaks are higher
People are (in some ways literally) hungry to work and climb the social ladder which even if worse now than it ever was is still much more present in America than it is in Europe
I can barely get people to come to my house to do construction work in Europe, while in America I'd have them working the same day, because people want money, because unlike Europe there's not much free gov money
That makes the system more oiled in a way because people WANT to work and that makes people work and build things
The problem is most Europeans will never ever respect "the hustle", they're stuck in the socialized welfare systems that worked in the 1960s and fairness, which is an absolutely beautiful ideal but stops working when you run out of money like Europe does now in 2025

Wait, so the reason 115200 baud is a common bit rate for UART is because its a multiple of 9600 (x12=115200).
And 9600 baud was commonly used because its 32*300 baud.
And 300 baud was used because its the lowest common denominator of 50Hz and 60Hz.
And that was used because telecom signals used to be clocked to the mains frequency?
So many examples of engineers just adapting around legacy systems because its easier to build upon stuff than reinvent stuff lol

I'm about to do something I think I've never done before, which is assert every bit of whatever authority I have as the person who discovered and wrote down the rules of open source.
After ten years of drama and idiocy, lots of people other than me are now willing to say in public that "Codes of Conduct" have been a disaster - a kind of infectious social insanity producing lots of drama and politics and backbiting, and negative useful work.
Here is my advice about codes of conduct:
1. Refuse to have one. If your project has one, delete it. The only actual function they have is as a tool in the hands of shit-stirrers.
2. If you're stuck with having one for bureaucratic reasons, replace it with the following sentence or some close equivalent: "If you are more annoying to work with than your contributions justify, you'll be ejected."
3. Attempts to be more specific and elaborate don't work. They only provide control surfaces for shit-stirrers to manipulate.
Yes, we should try to be kind to each other. But we should be ruthless and merciless towards people who try to turn "Be kind!" into a weapon. Indulging them never ends well.

I'm not against VC but I feel there's 2 types of VC startups
1) have an idea, build a product, get product market fit, grow, realize they need money, raise money, use it where they need it, improve product, get more users, when it makes sense either sell or IPO
2) move to SF, network with SF people, raise money from VCs that are now your friends, make a big flashy announcement that you have $$$ now, use the $$$ to rapidly pump your user numbers, now figure out how to sell the thing to friend of a friend's company for $500M
I think the first is building a startup, while the second is just high-level financial and social engineering
You can often predict a company's course if their announcements talk more about how much investment they got than their product
If I'd raise $50M maybe I'd not even tweet it? Just use it to improve the product and get more users and talk about that
Having $$$ in the bank tells me absolutely nothing about why I should use your product, it's not my money, it's your money, it benefits me as a customer exactly zero
If you post some really cool new feature you build, that makes me want to sign up and become a customer though

Did you know your MacBook has a sensor that knows the exact angle of the screen hinge?
It’s not exposed as a public API, but I figured out a way to read it and make it sound like an old wooden door.
