<p>No, we can't. It's an ultra-low-power embedded ARM Cortex-M33 (successor to Cortex-M4) processor, the right language to use when programming it is C++. You want a minimum of abstractions and a close-to-the-metal programming environment to maximize battery life.<p>Be grateful it's C++, it could be raw C.</p>

<p>Neat! I've got a slice that's under 10 miles long going south into town, but I've also got 14 slices to the north (the ones that don't intersect with a couple up-state cities) that are over 3000 miles long.<p>Vancouver is similarly interesting, a lot of great-circle 2000+ mile segments that reach over towards New England, but everything west or north is invalid.<p>Would be neat if instead of a single yellow petal to 100k, each petal was a color gradient to 1k, 2k, 10k, 20k, 100k, 200k, or 1M people!</p>

<p>I love the Garmin pogo chargers. I've got a few of their $3 puck cables scattered about my home, car, and office, a USB-C to Garmin adapter in my keychain and backpacking kit, and someone recently made a neat little portable battery that I wore under my strap in an ultra to recharge mid-activity.<p>Yeah, if you only use the stock Garmin cable (why isn't it at least right-angle?!) it kinda sucks, but there are lots of products that do it really well:<p><a href="https://www.amazon.com/dp/B0F5L632HM" rel="nofollow">https://www.amazon.com/dp/B0F5L632HM</a><p><a href="https://www.amazon.com/dp/B0D4F71WQC" rel="nofollow">https://www.amazon.com/dp/B0D4F71WQC</a><p><a href="https://www.amazon.com/dp/B07N18DX6Y" rel="nofollow">https://www.amazon.com/dp/B07N18DX6Y</a><p>I would much rather these totally waterproof surface-level pads that put the spring pogo pins in the cable than give up internal device volume to a USB receptacle or magnetic charging coils.</p>

<p>It matches my lived experience.<p>My body battery and stress often starts declining for no apparent reason and then 12-24 hours later I feel the symptoms of an illness. Similarly, when in a tough training block, HRV is a great tool to gauge how hard I ought to be able to go: I've tried to push through and just do a tough workout anyways when it's out of range, but failed to complete the workout in good form, or felt superficially crappy but had good training readiness according to the watch and was able to do better than expected.<p>The same holds true in the other direction, I don't log into Connect or scroll through the multitudinous widgets of data often enough to really keep tabs on this stuff, and when I get sick or feel good or bomb a workout or succeed at a workout when I felt off, the metrics consistently back up the actual results.<p>Personally, I've been thinking about jumping ship to a Coros Apex 4 if my battered Fenix 6 ever gives up the ghost - Garmin's prices are insane these days. At $270, this is cheap enough in comparison to a $1200 Fenix 8 Pro to take the chance. I could buy this and a $480 Apex 4, and then decide I didn't like either of them and go back to a used Forerunner 955, before spending as much as a new top-end Garmin.</p>

<p>There are only about 400 units in existence, and they just started shipping June 30:<p><a href="https://www.kickstarter.com/projects/unawatch/meet-una-the-modular-gps-sports-watch/posts" rel="nofollow">https://www.kickstarter.com/projects/unawatch/meet-una-the-m...</a><p>so it's been out for less than a month. That's why you've seen zero reviews on websites, it's an indie Kickstarter. They don't have the marketing budget of a big wearables brand.<p>It has a GPS, IMU, and heart rate sensor: That's enough, obviously, to track activities, workouts, and health which their competitors do with the exact same set of sensors. It remains to be seen how accurate those are, or how well the manufacturer and community can develop useful algorithms to turn raw sensor data into activity logs and actionable health insights, but step 1 is to release an MVP to get people wearing the watch and logging data, and step 2 is to use the data to improve the algorithms.</p>

<p>In my experience, a spec is often public (or available for purchase by the public from a standards committee for a few hundred dollars, close enough in business terms), but the source code for your competitor's implementations is not available for any price. The first barrier to entry to become a competitor in many industries is to implement an 835 page (note that those are rookie numbers) spec, building software that is compatible with existing data formats or legal frameworks or network protocols or hardware or whatever.<p>This is another example of the many invisible silos that developers end up in:<p>1. Some are developing enterprise software for use by their own employer, the spec only exists because it's useful to help the dev team manage the project. In this case, it's totally reasonable to expect the spec to co-evolve with the code.  If the release gets pushed out to Q3 or the target has to be adjusted due to unforseen implementation difficulties, so be it.<p>2. Some are developing contract software for their customers. The spec exists as a communication tool and requirements that allows the developers to know what to build and to inform the customer that what they've built has reached a certain phase of the billing process (including completion).  You're on a clock, and if you're late or you don't do what you said you'd do then your customer isn't going to pay you.<p>3. Some are developing software for abstract customers - either B2B or B2C. Often, the specs here are regulatory or industry-standard, implementing the spec is the function of the business.  You're releasing updates and new products to make year-end sales targets or snipe announcements by your competition, and advertising compatibility with various standards is a crucial bullet point in the sales presentation.<p>Bug reports, feature requests, and especially deadlines have different meanings in each context. The way AI development agents can be used in each silo also varies enormously!</p>

<p>If you're willing to put a little time into video editing, a 360 cam is great. The insta360 tools can make that a little easier if you want something simple.<p>If you just want to store a snapshot of the moment as it was captured, a regular camera that you pointed in the right direction is better.</p>

<p>I think that any workflow that requires the user to stare at the tokens being generated live is using it wrong. Delegate, don't stare!<p><a href="https://mikeveerman.github.io/tokenspeed/?rate=10&mode=text" rel="nofollow">https://mikeveerman.github.io/tokenspeed/?rate=10&mode=text</a><p>You think of an idea that you want to have the LLM process, queue it up, and go back to what you were doing. Once you've finished reading the next article on HN about a 5 tps Xeon, your task will be complete. It's kind of like using a 3D printer: It doesn't matter if a print takes 10 hours, because when you come back in the morning it will be done.<p>Yes, with top-tier GPU farms you can hit hundreds of tokens per second. But if the old Xeon in the closet can get useful work done at 5 tokens per second, there are lots of people and lots of use cases where a free, unlimited 5 TPS stream is worth more than paying a dollars per day to get access to a 500 TPS source.</p>

<p>Humans easily anthropomorphize things that are not humans, ascribing human attributes like motive and comprehension and emotion to objects and processes that are not people who can have those attributes.<p>Claude is not a human.<p>It is overwhelmingly easier to anthropomorphize Claude or Siri or an LLM that communicates with you more eloquently than your boss than it is to anthropomorphize a cranky, tired starter motor. It's often easier to do than it is not to do, and sometimes, it's a useful abstraction. But it's not precise or correct, and can result in errors.<p>It could also just be that they're getting confused when using tools configured without a username dedicated to the tool. It's easy to end up with a comment or commit message that says "I prefer X over Y" posted on Alxndr's account and have coworkers confused whether that's the LLM or the human making that statement.</p>

<p>What they meant when they said "planets" was the 8 (previously 9, previously to that 8, previously 7...) known and named planets in our own solar system. A hypothetical "Journal of Planets" that was actually about solar system astronomy wouldn't necessarily have known what to do with a new paper about 51 Pegasi b published 30 years ago. They're thinking "when we said planets, we actually always meant solar system planets, it just never came up until now".<p>The reviewer of this paper is saying that by biology they always meant naturally evolved cellular biology, not synthetic biology - there's just never been an example of the latter before.<p>I think the take is wrong, the receiving journals should be excited to expand their scope rather than frustratedly redefine their scope more narrowly, but definitions and categorization are hard.</p>
