Just move your funds from mutual funds tracking NASDAQ (if you own any) to a different fund tracking S&P. Inconvenient but not the end of the world. You still have about two weeks to do so; I did this last week. Then in 6+ months when lockups expire and insiders have dumped, you can move money back if you'd like.

Also, SpaceX only sold a tiny portion, and Elon is only a trillionaire based on unrealized value of unsold stock. If it crashes before he sells any, he might go back to being a "normal" centi-billionaire.

IMO the US administration actions are less about actually caring whether foreigners have access to these tools, and more about legal/political precedence. In the US there's a long history of executive or legislative branches crying "national security" to shut down things they don't like, and courts will rarely stop them (or do so extremely slowly after months of deliberation.

(The other common cry is "child sex abuse" but for obvious reasons this administration is less interested in talking about that particular topic.)

Idk what they're using for serving, but it's truncated in the raw HTML, not just the presentation layer. So probably a bug on the backend somewhere? The linked github repo doesn't seem to have the contents of the post.

Nice to see some catch-up with Anthropic and others, but this doesn't actually offer cloud coding agents (my favorite Claude and Cursor capability).

I want to code from my mobile device when my laptop is off or unavailable, pushing PRs directly to GitHub. Codex mobile only works with a desktop machine, at which point, I'll just use that machine, what's the point.

I experimented with setting up a dedicated openclaw instance for coding via chats on mobile, but now that cursor and Claude both offer easy coding from the Web/app, I have had it turned off for weeks.

I avoided this exact scam. The most important thing is to never trust an incoming phone number. If they can't give you a publicly posted phone number that you can call inbound, they are a scammer.

Google has dozens of properties and it is easy to generate an email from one of them that seems to confirm the attacker's identity. Never trust any of these to identify a legitimate representative.

Can anybody understand how it detects cheating (throwing your phone off a tall building)?

Assuming it's just using the accelerometer to detect freefall, is there any way to distinguish ascent and descent? GPS is probably too inaccurate and too high-latency to assist here.

Perhaps it can tell the difference between reaching terminal velocity and crashing into the ground, and it penalizes the former?

I also recently went through the Coinbase interview process, and was pleasantly surprised that they offered this compensation for the take-home interview part.

Overall, a 4-6 hour task, to be completed on your own over a 1-week period, seems reasonable to me.

This proof is nearly equivalent to that proof, but uses the sine function to generate a contradiction. The crucial step involves the fact that:

1 + 2 * product(p', p')

must be divisible by some prime number, where

product(p', p')

is the product of all primes you were talking about.

I would be surprised if this doesn't constitute a violation of Terms of Service somewhere along the line? Something that could provide grounds for one of the telecom companies involved to have it taken down, if it were to be successful.

Basically, it means that you can send information (in one direction only), without paying for use of the telecom network. Taken to an extreme, it should be possible to create a "free walkie talkie" app that worked all over the world, for free, by repeatedly calling back and forth but never connecting the call.

I recently spent some time working on exactly this, in 2D:

To see what it looks like, you can check out this youtube video:

I wrote an engine that modeled object positions as "timelines", where position varies with time, and demonstrated the basic relativistic effects (length contraction, time dilation, and frequency shifting). Unfortunately, I never really figured out how to turn these into actual game mechanics.

I recently spent some time trying to turn a 2D simulation of Special Relativity into a game:

A friend of mine setup a simple PHP-based proxy while he was in high school, to get around the firewall.

Then, he modified it slightly to scrape facebook username/passwords, and gave the URL to all his friends. :)

I wonder whether modern security practices (e.g. https everywhere) will make proxies less lucrative (and therefore less common).
