arj··on DeepSeek v4.1 Flash
Having this available to find and fix security stuff is a big deal. The model of really good.
arj··on Bun 1.4
Bun is still massive, my hobby attempt at smaller confined js/wasm https://github.com/arj03/seedkernel/
arj··on DeepSeek V4 Pro 0813
That said. It is really good at security review at max settings. Just ran one, it came to 0.15$
arj··on DeepSeek V4 Pro 0813
Been testing this on hobby project https://github.com/arj03/seedkernel/. Latest flash was a big step up. Pro feels really slow compared. Claude opus is still better day this level.
arj··on Claude Opus 5
On a Friday, I'm out of tokens ;-)
arj··on DSpark: Speculative decoding accelerates LLM inference [pdf]
You ask me what I think. So far deepseek has been very consistently trying to advance state of the art research in a transplant and public way by writing papers and publishing working code. They are also not at the mercy of the stock market in the same way many Americans companies are. Before anyone assumes too much, I live in Europe.

Not everyone is motivated by greed
arj··on Baochip-1x: What it is, why I'm doing it now and how it came about
It seems it had hardware support for secure mesh. Anyone know what that is?
arj··on Tesla Sales Fall Off a Cliff Globally, Including Germany, Australia, and China
Good riddance
arj··on Grok3 Launch [video]
Still no post on their official blog. How disappointing.
arj··on PQConnect: Automated Post-Quantum End-to-End Tunnels
Does not seem like the source code is available?
arj··on New discovery reveals how diatoms capture CO2 so effectively
I was looking into the numbers and what I could find was that is more like 350 than 750. Source: https://climate.mit.edu/ask-mit/how-much-carbon-dioxide-does.... Still interesting fact not often cited.
arj··on Since spring of 2023, the world has been warmer than climate models anticipated
Coal in China is declining.

"In the first half of this year, China permitted only 10% of the new coal plants as the same period last year."

arj··on Since spring of 2023, the world has been warmer than climate models anticipated
We have a finite amount of carbon left. Each year we are already exceeding our share. This in itself means that future generations have less. At the same time, some people use more than others. It's not a matter if degrowth but about sharing ressources fairly.
arj··on Since spring of 2023, the world has been warmer than climate models anticipated
We all live in the same planet, the most reasonable way to share this is that we get an equal share. For far to long certain countries have taken up much more of their share. To such a point that our whole carbon budget has been used in a single or two generations. Now is the time for those better of to contribute their fair share in solving this mess.

You mean China that built more solar last year than the rest of the world combined? Not to mention batteries.
arj··on Empathy for the user having sex with your software
Serious question. Do you put buttplug.io on your CV? :)
arj··on Denmark recalls Korean ramen for being too spicy
The spice must flow
arj··on How I think about debt
It is
arj··on My productivity app is a never-ending .txt file (2022)
I have a similar system, I have the latest 3 + active in one org buffer and the rest in separate files. Mostly use org mode for expanding headers. Super fast search for anything is the killer feature.

arj··on Billions in 'unknown' funds flowing into Canada's housing market [video]
Denmark also has no capital gains tax and the housing prices has also gone up like crazy over the last year.

I guess the thinking must be that if it were taxed and say you bought a house for 500k and a decade later it is worth 750k and you have to move for another job to a place where a comparable house would also be 750k$, then you can't afford the "same house" any longer because you have to pay tax on the 250k gain. The funny thing is I don't think we would see this kind of increase on the house price if it where taxed, making the point pretty mood.

Does anyone know of a country with tax on capital gains from selling a house and how the prices on houses are there?

arj··on Scuttlebutt – A decentralized secure gossip platform
There is a browser based demo you can try out at: https://between-two-worlds.dk/.

It's the latest build of https://github.com/arj03/ssb-browser-demo.

If you need an id to follow to get some data, you can try following @6CAxOI3f+LUOVrbAl0IemqiS7ATpQvr9Mdw9LC4+Uv0=.ed25519. You need to manually add either a room or a pub under connections first.

arj··on Scuttlebot: Peer-to-peer database, identity provider, and messaging system
Can run directly (https://github.com/arj03/ssb-browser-demo) in the browser as well.
arj··on SQL Operations Studio
This is actually quite decent for a first version. I can see that it has git integrated. What workflows do people use to combine git and sql?
arj··on HTTP is obsolete. It's time for the Distributed Web (2015)
But it is scaleable. On scuttlebot you follow people just like you have friends in real life. I also don't need to ask the government permission to talk to that person. That is DEcentralized for you right there.
arj··on Show HN: Get encrypted data from people that don’t know how to encrypt
This is really smart, especially with something like protonmail.
arj··on Instant.io – Streaming file transfer over WebTorrent
Does anyone know if this works privately. Or if there is a good way to seed files only between friends?
arj··on A Conflict-Free Replicated JSON Datatype
That last part is a good summary of CRDT versus OT.

Also nice project. I think a section on conflict handling would be a good addition to your README on github. It is the first thing I look for when looking at systems in this space :)

arj··on Tor Browser 4.0 is released
The ability to update easily is a very nice addition
arj··on Show HN: Streisand – Silence censorship, automate the effect
Sweet thanks, great project!
