clysm··on Data centers in space makes no sense
3. There are WAY more things to get corrupted on a computer system than tokens. And non-determinism does NOT mean it’s tolerant to faults. Random values are intentionally introduced at the right moment for LLMs.
clysm··on Show HN: An interactive map of US lighthouses and navigational aids
Nothing in Michigan? The state with the most light houses out of any in the US?
clysm··on Mathematicians have found a hidden 'reset button' for undoing rotation
Kind of like… a “hidden reset”…
clysm··on Scammed out of $130K via fake Google call, spoofed Google email and auth sync
Chase bank…
clysm··on I bought the cheapest EV, a used Nissan Leaf
No. It’s 100% a design choice by the manufacturer to make them look weird.

Even with the benefits of EV packaging, manufacturers chose to make them “different” on purpose, which really put off the vast majority of buyers. Tesla had so much success because they were practically the first manufacturer to make something look somewhat normal and have good stats.

Now, BMW finally learned and has their 4 and 5 series EV cars share a common platform with the ICE. There is no physical difference in style other than the front grill.

clysm··on GitHub pull requests were down
Why is this linking to a merged PR, or a PR at all, and not a status page?
clysm··on I tried living on IPv6 for a day
More than just IPv4 priorities, almost all other IPv6 addresses are given higher priority which makes routing between ULAs on an internal network problematic.

That draft doc seems to fix multiple problems at once.

clysm··on The day someone created 184 billion Bitcoin (2020)
A forced migration is basically just making a brand new system. It’s not a “protocol fix”.
clysm··on The day someone created 184 billion Bitcoin (2020)
And what happens to all those cold wallets where people can recover the secret key or forge signatures for it? They money is just gone, either by thieves or the network disallowing them to be spent.
clysm··on The day someone created 184 billion Bitcoin (2020)
It helps build a new system, but all existing wallets would be hackable until they migrate. And we expect everyone to have the time and resources to do that? For a “store of value” system?

All of my hardware wallets are now worthless? All of the hardware security modules used for wallets managed by corporations no longer work?

It's an absolute mess for so many reasons that a "protocol fix" just doesn't cover.

clysm··on The day someone created 184 billion Bitcoin (2020)
I really hate the “someone will certainly solve this problem!” mentality.

You can’t just magically update the protocol to work around the ability of someone to break elliptic curve cryptography. That not how this works. It’s not how any of this works.

clysm··on LLMs should not replace therapists
Except LLMs that tell the student wrong answers, or the person needing therapy to kill themselves.
clysm··on Next month, saved passwords will no longer be in Microsoft’s Authenticator app
It is that trivial. The problem is vendor lock-in and no common, defined way to export/import them securely (which is going to change soon).
clysm··on Bypassing GitHub Actions policies in the dumbest way possible
I’m not seeing the security issue here. Arbitrary code execution leads to arbitrary code execution?

Seems like policies are impossible to enforce in general on what can be executed, so the only recourse is to limit secret access.

Is there a demonstration of this being able to access/steal secrets of some sort?

clysm··on The Xenon Death Flash: How a Camera Nearly Killed the Raspberry Pi 2
> Most PCBs aren’t distributed to consumers as bare PCBs, so this issue rarely appears to end users.

In terms of hobby/maker electronics, embedded systems, etc., which the Raspberry Pi falls under, yes they absolutely are. The entire Arduino ecosystem is like this.

clysm··on A server that wasn't meant to exist
Why the hell is there a line break after every sentence?
clysm··on Claude's system prompt is over 24k tokens with tools
No, it’s not a threshold. It’s just how the tech works.

It’s a next letter guesser. Put in a different set of letters to start, and it’ll guess the next letters differently.

clysm··on Sycophancy in GPT-4o
Absolute bull.

The writing style is exactly the same between the “prompt” and “response”. Its faked.

clysm··on Samsung Q990D unresponsive after 1020 firmware update
Yes it does work… with an A/B update system.

Android systems can do this today. After an orderly shutdown of new software, then it can mark the new stuff as good and not allow older software to boot.

clysm··on New battery-free technology can power devices using ambient RF signals
You create an RF shadow, not a black hole.
clysm··on New battery-free technology can power devices using ambient RF signals
Harvesting RF ambient noise is not new. Here are some commercial products:

Also, crystal radios are really old.

clysm··on Why does storing 2FA codes in your password manager make sense?
> There was and is absolutely nothing wrong, and quite a lot right, by having the 2FA program completely separate from your password vault.

Did you read the article? That's what they say.

> For maximum security, you can store your 2FA token elsewhere ... but for general purpose use, storing your 2FA in your password manager is an acceptable solution due to the convenience benefits it provides.

clysm··on SSH Artwork
Where's the proof that this works?

It's a brute forcing tool with the goal of finding the desired fingerprint, but there's no demonstration of it actually working.

clysm··on EUCLEAK Side-Channel Attack on the YubiKey 5 Series
Doubtful once the attack is refined. Their capture requirement of 200 traces is trivially low.
clysm··on Anomalous contribution to galactic rotation curves due to stochastic spacetime
The fuck... I can't believe what I've just read. That's like saying Newton set us back over a hundred years.

There was no regression because of Einstein.

clysm··on How to (and how not to) fix color banding
Yes, on the first gen of retina display, LG panels were prone to image retention, while the Samsung's were not.
clysm··on Linux: Ext4 data corruption in 6.1.64-1
> so it's nothing to worry about

Except for debian bookworm stable.

clysm··on A software epiphany
People are refusing to read out of principle. We shouldn't have to work around a bad and annoying "feature" of a site.
clysm··on Android 14 introduces cellular connectivity security features
Lockdown mode is iOS 16.
clysm··on Corporate profits account for almost half the increase in Europe’s inflation
Show me how many new auto companies and farmers entered the market then to solve the supply and costing issues that we continue to have.

The theory sounds great in an Econ 101 classroom, but is problematic in practice.
