> Among the records revealed during the discovery process in these cases are intercepted Signal chats, ...

I asked claude how ICE was able to intercept signal chats and it seems like it wasn't a failing of signal's encryption, but rather there were some semipublic signal chats that agents were able to join.

And once they joined these signal chats, they launched a privilege escalation attack - in claude's words:

> In one case, an activist posted a license-plate lookup tool, hosted on Fly.io, to an infiltrated chat. Agents then got the service’s DNS queries, Stripe data, SSH logs, and the signup IP, and matched them with DMV records and Thomson Reuters CLEAR data to find a driver’s license number and other personal records. This was reportedly done by buying data from a commercial broker rather than getting a warrant.

I don't understand your position.

First you say you don't like that they're accessing the corporate bond market, which is something all public companies can do.

Then you say they should've IPO'd earlier when they were even earlier stage and riskier .. which would allow them to issue bonds even earlier?

What is your position? Or are you complaining for the sake of complaining?

claude code and friends will make it much easier to rewrite python/js/$memory-hungry code in rust.

Overheard at a battery conference: western battery suppliers are actually copying (or in your words, stealing) the Chinese electrolyte formulas and other designs.

Great artists steal, the US and Europe play the same game.

Re:Tell HN: Disable adblocker when researching startup ideas on Friday February 11, 2022 @03:45PM (#30306776)
I jot down my notes in a google doc and paste links that I want to save.

If I really like an idea, I'll use these notes to write out a larger form memo that touches on GTM, product strategies, tech stacks, competition, etc.

Tell HN: Disable adblocker when researching startup ideas

Like many of us on here, I do all my web browsing with ublock origin enabled and am pretty happy with that.However, researching startup ideas is the exception where I do want to see ads and prior work and others trying to sell their services. Ads very helpfully highlight potential competitors and now I do my research in a dedicated browser session without adblockers :)

Re:Amazon hid its safety crisis on Tuesday September 29, 2020 @06:30PM (#24633804)
At the risk of defending a faceless megacorporation, I'm curious what injuries per package look like at Amazon vs "Industry Average".

According to the article, productivity expectations per worker doubled with robotics, and Amazon has about double the injury rate per worker, so my super rough back of the envelope calculation says they should fare similarly on that metric.

If the industry alternative takes twice as many workers to do the same job, ultimately leading to approximately the same number of injured workers, has Amazon really created a safety crisis?

Have you heard of this thing called quantum computing?
The article did say that the motivation for doing so was because AWS credits were running out .. why prematurely optimize a free resource? :)
Re:Show HN: Coronavirus Mask Usage Simulations on Friday May 22, 2020 @04:06PM (#23276335)
I built some coronavirus simulations to explore the impacts of our actions in a virtual environment - let me know what you think!

Goals of this project are to spread high quality information around and use some basic monte carlo / bayesian ideas to show the impact of individual actions on the individual.

You may also be interested in https://coronavirus.simrnd.com/shopping_solo/, an earlier simulation that explores the impact of sending out 1 person to shop vs 2 per household.

The simulation engine is written in Rust at https://github.com/jinpan/covid-simulations, which is compiled to WASM to run on the browser.

Yeah that would be incredibly useful for testing policy in a simulated environment before releasing into the wild :)

One of the hardest challenges is "How do we choose realistic parameters for how the virus spreads? Infection duration? Mortality?"

But if we can incorporate the latest research and Monte Carlo simulate with ranges for the above parameters and find policies that are robust against those parameters, I think it would be an enormously powerful policy tool. Additionally, I think it could bring transparency into the decision process, something the public lacks.

If you want to contribute to the effort I started, the simulation code is open source at https://github.com/jinpan/covid-simulations. The engine is in Rust, which is then compiled to wasm.

Semi-related: I'm working on agent-based simulations for coronavirus, exploring our individual actions affect outcomes.

In the first simulation, I take a look at single/dual shopper households and explore how choice affects viral spread on a societal level, and then on am individual household level.

> Legendary investors Stan Druckenmiller and David Tepper were the latest to weigh in after a historic market rebound, saying the risk-reward of holding shares is the worst they’ve encountered in years.

True, but what are they going to do about it?

They would be hard-pressed to find a rewarding asset class today that has billions in liquidity, with less risk.

If they hold cash/tbills, they risk losing a good chunk to inflation from the new monetary policies.

They could try to hedge for a market crash, but timing it seems difficult - the market can remain irrational longer than they can remain solvent. And hedges are aren't cheap with the higher IV levels today.

I've been working on a coronavirus simulator in rust/wasm.

https://coronavirus.simrnd.com/about/ is a draft of the intentions of the project, and the source code is at https://github.com/jinpan/covid-simulations.

I'm aiming to publish a blog post with some initial simulation results by the end of the week.

I gradually graduate a notebook by extracting what I can into libraries, and importing those utilities into the notebook. Eventually the logic in the notebook becomes trivial enough to easily convert into a production program.

I'm interpreting this as (maybe unintentionally) creating new forms of debt - next time you want to visit the zoo, you may need to resolve some favors to the zookeeper that let you into the yak exhibit.

The persuasive effects of these fake friends on (political) advertising are terrifying.

Re:It’s Time for Some Queueing Theory on Thursday June 27, 2019 @01:24AM (#20291942)
Another fun surprising result from queuing theory is that if you have a buffer of pending RPC's that have some deadline, it is better to service them in a "unfair" LIFO order, as opposed to a fairer FIFO order. [0] goes into more gory details.

In the bank example from the article, LIFO would dramatically shorten the median wait time (~5 minutes), at the cost of really upsetting customers [1]. In the case of a support queue, where the waiters are blind to each other, this cost could be reconsidered ...

Rivest invented the 3-ballot voting protocol (see https://en.wikipedia.org/wiki/ThreeBallot)

The trick to the 3-ballot voting protocol is that not everyone can validate their vote. However, when a group of voters band together, they should be able to validate that a subset of their votes (1/3) were registered with high probability.

With a sufficiently large group of voters checking results, the law of large numbers comes into play and they can statistically detect the presence of voting fraud.
