<p>They probably update these answers offline. I tried "how do you profit from options" and got:<p>> Call Options: You buy these when you believe a stock's price will go up. If the stock rises past your strike price, the option's value increases, allowing you to sell it for a profit or exercise it to buy the stock at a discount.<p>> Put Options: You buy these when you believe a stock's price will go down. If the stock falls below your strike price, you profit.<p>Which leaves me wondering if changing the search textually busts some cache that they update using a slower/smarter model.</p>

<p>I don't know how much it has to do with the administration and the top-level comment here was flagged so I'm lacking context but American exceptionalism is instilled here from birth so it does not surprise me in the slightest that founders grow up with the idea that they are built different and destined to change the world. Acting out the fantasy via fraud takes a special kind of person. It's not clear to me whether the dishonesty is uniquely American but I somewhat doubt it. The color of the delusion is, however.</p>

<p>If someone cared enough to spend money on this I think it would be an easy to medium difficulty project to use an FPGA and a CSI-2 IP to pretend to be the sensor. Good luck fixing that without baking a secure element into your sensor.</p>

<p>You're off base here for what may be a rather subtle reason. While I am not a marxist, I do think that the purchasing behavior of the wealthy makes much more sense when you think about things in terms of the labor theory of value.<p>The evidence for this is all around us. As automation of manufacturing has brought former luxuries into reach for middle-class families, those with means move on to consuming items that require more and more labor to produce. "Handmade" scented soaps. "Artisanal" cheeses. Nobody with money wants their wedding invitation to arrive at a destination with machine-canceled postage. It's tacky. Too automated, too efficient. In fact, I bet the ultra-wealthy don't even use postal mail for delivering their invitations, because it's not labor-intensive enough to be tasteful. Private couriers are probably the move. You can see this pattern over and over again once you know what to look for.<p>There will always be a demand for human labor, because value is a human construction. That said, the rate at which the economy will change because of AI (if the True Believers are to be believed) is probably too fast for most workers to adapt, so you may not be entirely wrong in your conclusion depending on how thing shake out, but the way you got there is bogus imo.</p>

<p>Over the last few weeks I’ve been hard at work building a FOSS maps app for Android from the ground up based on Material 3 components and industry standard maps tooling. It has online and offline modes, and integrates well with self-hosted maps services like Headway[0] deployments. I’m really quite pleased with it and I hope others enjoy using it as much as I’ve enjoyed making it. I’m about 2 weeks in to development so expect some bugs. But it has most of the features you’d expect like search, directions and navigation. It’s shockingly usable already.<p>I’ve been yearning for something better in the FOSS maps space for a long time. I don’t think I’m the only one. I’m really hopeful that Cardinal Maps can grow into that something for myself and others.<p>If you’re stoked about this project I’d appreciate contributions and beta testers. There’s an obtainium link in the repo README.md if you want updates. :)<p>[0] <a href="https://github.com/headwaymaps/headway" rel="nofollow">https://github.com/headwaymaps/headway</a></p>

<p>My guess is that they're using FastText for semantic search, so it's more likely to break queries like "coffee near me" than address search, the latter likely being handled by tantivy. For context, I've also written a geocoder [0] based on tantivy. :)<p>[0] <a href="https://github.com/ellenhp/airmail" rel="nofollow">https://github.com/ellenhp/airmail</a></p>

<p>There are a few piece of this that rely on proprietary data, especially the FastText training step, so that's a dead-end unfortunately (would love to be proven wrong). I'd consider subbing in a small bert model with a classifier head for something FOSS without access to tons of user data, but then you lose the ability to serve high qps.</p>

<p>Sibling commenter covered most of what I have to say but the other reason this is wrong is because many bicycles can go 20-30mph, and I'm just going to leapfrog you anyway at the red light you're racing me to wait at.<p>Other times cars try to kill me to save themselves a few seconds:<p>1. turning right into a parking lot ahead of me<p>2. turning right out of the parking lot ahead of me<p>3. rushing to open their driver's side door right in front of me so they can get out and get to their destination faster<p>I've had a crash for #1 and #3, so this isn't theoretical. Watch for bicycles.</p>

<p>Well there are two competing factors, one of which you pointed out--not every woman who experiences harassment reports it. The other which may be less obvious is that the people who behave this way tend to do so not only repeatedly but frequently. Eventually they may harass the wrong woman and get reported. Without knowing the numbers I can't speculate more about whether lyft knew about the driver who harassed me.</p>

<p>I've been treated to the the "you're so beautiful, do you have a boyfriend" act about 2% of the time[0] I get into a stranger's car pretty much across the board, which makes me a little bit skeptical about whether these companies do meaningful oversight. It's possible that these incidents go mostly unreported though. I didn't report mine.<p>As an aside, this is why I generally trust public transit more whenever it's an option. The worst case scenario is just so much less sinister when there are other people around than it is in a car alone with a stranger.<p>[0] once in a lyft in seattle, the other in a taxicab in barcelona. figuring I've taken about 100 lifetime solo car rides with strangers which is probably an overestimate.</p>

<p>> existing remotely exploitable wireless security vulnerabilities<p>That's just it though, in my opinion being able to flash the thing at all would count as a remotely exploitable wireless security vulnerability. The first thing I'd do if mine was flashable is lock it down to make sure it was no longer flashable. Does that make sense? I might not be articulating myself well here.</p>

<p>Disclaimer I don't have a pacemaker: As a biohacker, I think this is a really bad take. I regularly put things [1] in my body of questionable provenance, and then cut them out of myself without anesthesia when they don't suit me anymore, but I like being alive too much to mess with a medical device like a pacemaker. Pacemaker hacking sounds hardcore and like, respect to anyone who does it but I don't think it should be easy to flash one of those things because I'd really prefer nobody do that to me in my sleep.<p>[1]. <a href="https://dangerousthings.com/" rel="nofollow">https://dangerousthings.com/</a></p>
