mhmmmmmmon SkillsBench: Benchmarking how well agent skills work across diverse tasks

I don't think thats necessarily true, they aren't really capacity constrained in practice (they might be behind the scenes and adjust training on the fly, but thats speculation), so wasting tokens effectively helps utilize their (potentially idle) inference GPU's

mhmmmmmmon Cursor 1.0

They add Claude Code to the pro plan yesterday: https://x.com/_catwu/status/1930307574387363948

mhmmmmmmon TradeExpert, a trading framework that employs Mixture of Expert LLMs

Removing the "Market expert" which uses OHLCV (Open, High, Low, Close, Volume) also drops the sharpee from 5.01 to 1.88 while also increasing the max draw down to 13.29% (v.s. 9.70% for the index). I'd be very surprised if the pre training of the base model was the only source of leakage...

mhmmmmmmon Claude's system prompt is over 24k tokens with tools

They certainly do, and also offer the tooling to the public: https://docs.anthropic.com/en/docs/build-with-claude/prompt-...

They also recommend to use it to iterate on your own prompts when using Claude Code for example

mhmmmmmmon Ladder: Self-improving LLMs through recursive problem decomposition

There is https://www.rwkv.com/ which is an LLM based on RNN's, thus having "infinite" context length, it comes with its own tradebacks though. (Notably that its impossible to actually store infinite information in the network, so it prunes based on which information it finds more important.)

mhmmmmmmon Bybit loses $1.5B in hack

https://x.com/tayvano_/status/1847877011462901915 This thread has some info about very similar past attacks, should give some insights into the level of sophistication that goes into something like that.

mhmmmmmmon Bybit loses $1.5B in hack

Bybit was quite literally using Gnosis Safe for the compromised wallet.

mhmmmmmmon Javier Milei backtracks on $4.4B memecoin after 'insiders' pocket $87M

> This is not something you can just log in on Binance and buy with cash in a single click.

You would've definitely been able to buy it with cash and a few clicks, for example using moonshot. (And I'm sure a couple other / similar platforms)

mhmmmmmmon Can LLMs write better code if you keep asking them to “write better code”?

Is reliably detecting if code has any infinite loops feasible? Sounds like the halting problem.

mhmmmmmmon Jump Trading, Virtu and the 'hidden optical fibre cable' under an Ohio field

So now I probabilistically spam a ton of different orders to on average get my desired fill... This just turns it into a "whoever is best at DoS'ing the exchange" game. As the orderbook fills with competitor orders it makes sense for yourself to also spam orders so each of your orders maintains the same probability of being filled

mhmmmmmmon Jump Trading, Virtu and the 'hidden optical fibre cable' under an Ohio field

Taiwan Stock Exchange used to have quantized trading times (read "frequent batch auction"), but it led to worse price discovery and a bigger bid ask spread: https://focus.world-exchanges.org/articles/citadel-trading-a...

> Our analysis of the TWSE’s transition clearly demonstrates that continuous trading results in better liquidity provision, lower bid-ask spreads, more stable prices and enhanced price discovery, as well as higher trading volumes.

mhmmmmmmon Jump Trading, Virtu and the 'hidden optical fibre cable' under an Ohio field

CLOB's force market participants to compete on pricing (which is only indirectly related to latency, since you can quote tighter if you know your orders won't get picked off by other, faster, traders) Taiwan used to have Batching style auction and it ultimately led to worse prices: https://focus.world-exchanges.org/articles/citadel-trading-a... > Our analysis of the TWSE’s transition clearly demonstrates that continuous trading results in better liquidity provision, lower bid-ask spreads, more stable prices and enhanced price discovery, as well as higher trading volumes.

mhmmmmmmon An anonymous donor just sent 299 Ether (equivalent to 393k USD) to redox_OS

Interesting sidenote: The donor also left a message for two other operating systems, "Qubes address? GrapheneOS address?". https://etherscan.io/tx/0xca5bb04204f446f73a510ea02b2bd7c01e...

the remaining 2 companies could be anything, just not banks.

mhmmmmmmon Ask HN: How to ask employer to match inflation rate, independent of pay rise

Inflation incentivizes spending, money sitting in a bank account doesn't make the charts go up.

mhmmmmmmon Some interesting malware I found

Not so sure about that in this day and age: https://googleprojectzero.blogspot.com/2019/08/a-very-deep-d...

mhmmmmmmon Solar-powered robotic beekeeping

I mean a generation of bees takes atleast a year since only the queen is really reproducing, the worker bees themselves aren't exposed to any evolutionary pressure since they can't reproduce. (I guess they are by proxy, once their queen dies so does their lineage)

mhmmmmmmon Almost every publicly available CVE PoC

There is Exploit-DB which contains a list of PoC for a lot of services, if their count is to be believed its almost at 45k different PoC.

mhmmmmmmon Attacking an Ethereum L2 with Unbridled Optimism

You still have transaction costs in the form of transport costs to get the gold to your personal location.

mhmmmmmmon A Quadrillion Mainframes on Your Lap

> I wish there existed a modern cross-platform open source reactive GUI framework which was less of a resource hog than Electron

Flutter (Desktop) comes pretty close to that. Its really fast to write and your code works on IOS/Android/MacOS/Windows/Linux unless you need Platform specific API's, and even that is possible.

mhmmmmmmon Earth system impacts of the Great Dying in the Americas after 1492 (2019)

mhmmmmmmon Apple announces Self Service Repair

This is great! I wonder what the prices will look like, there has to be a catch...

mhmmmmmmon Will the climate crisis force America to reconsider nuclear power?

Modern Nuclear reactors are incredibly save.

mhmmmmmmon Ask HN: Freelancer? Seeking freelancer? (November 2021)

Just a heads up: the E-Mail on your resume isn't displaying properly: "Email: ${first_name} + ‘@’ + ${domain}"

mhmmmmmmon US Series I Savings Bonds Now Yielding 7.12%

This particular Bond yields current inflation levels:

"How is the interest rate of an I bond determined? The interest rate combines two separate rates:

A fixed rate of return, which remains the same throughout the life of the I bond.

A variable semiannual inflation rate based on changes in the Consumer Price Index for all Urban Consumers (CPI-U). The Bureau of the Fiscal Service announces the rates each May and November. The semiannual inflation rate announced in May is the change between the CPI-U figures from the preceding September and March; the inflation rate announced in November is the change between the CPI-U figures from the preceding March and September."

So its fairly safe to assume that current inflation levels are indeed 7%.

mhmmmmmmon Avoiding bot detection: How to scrape the web without getting blocked?

Its fairly trivial, some stuff needs a modified browser executable or some JavaScript magic but it wont take you longer than 2-5 Hours to bypass most of the heuristics, disabling the window.navigator.webdriver flag and getting a residential IP is on its own enough to get single click captchas every 1-2 tries for example. To be fair I haven't looked into it since 2019 but i doubt that its gotten much harder.
