Don't misunderstand me: mavlink gets the job done which is better than nothing. But its use requires careful consideration about scope and error handling -- more careful than should be necessary if COTS were used instead. I seriously wish I could have a few years to rewrite the whole stack.

> I am tolerating it for now for gimbal operations

Make sure you're using latest (there was a recent fix to a crash in the gimbal manager and reconnect code recently). The mavlink guys are usually pretty responsive to mavlink support questions on Github issues and discord. Many of the vendors are also on discord, useful if you're integrating with components.

> I need 1 byte for payload size, 1 byte for message type, maybe 1-2 for CRC... the rest of the header is a liability for OTA transmission time.

Yup, exactly. If the component and you are both already connected to an IP network then there are more industry standard protocols to use which perform better (battery, bandwidth, latency, the whole shebang) perform in a more expected behavior (a single message to a single IP destination is has well-defined routing rules, but a single mavlink message is likely broadcasted and possibly broadcasted multiple times (even when deployed to a single system), and can be secured better because security tools talk IP.

You mention DroneoCAN - I assume that's a typo for DroneCAN [0]. Can you use ROS2 [1]?

Contrast ROS2 with mavlink. The communication layer between different ROS2 components (nodes) can be changed for different implementations of transport and I've seen things like shared-memory (same-host, saw it at a drone conference) or replacing with another COTS (I don't remember which one though, but I think it was ZeroMQ or based on it).

If you can provide a ros service then that's a step in the right direction as far as I'm concerned. ROS already has existing services to interface with CAN [2]. Even if you have some specific reason to need DroneCAN, there appears to be a an example for using ROS2 to talk to DroneCAN [3].

I don't know! I think the subtext of the article is that the Tsimané have, ceteris paribus, a lower incidence of dementia --- that if you could keep the lifestyle and environment constant and raise the at-birth life expectance of these people to modern standards, they'd still have low rates of dementia. I'm wondering if that's true, and how you'd go about investigating that.

> If you are an extreme introvert or find it difficult to be assertive you have a tremendous amount of catching up to do

This can be a good thing. "Natural born leaders" by personality type tend to be overconfident and ignore their blindspots because they've never had a reason to challenge their ability.

Introverts, for example, are acutely aware that leading and managing doesn't come naturally and is a skill that is continually learned and built upon. In the long-run, introverts can be excellent leaders because they're aware of what it takes to be a good leader and they put an emphasis on professional development to get where they need to be.

Not to say extroverts are worse leaders. Both introverts and extroverts can be terrible leaders/managers. The best leaders/managers are the ones who have the self-awareness to reflect on themselves, identify their week points, and constantly improve.

It seems crazy to me that you think people are incapable of doing things to add or detract from the happiness of others.

AI is going to push data autonomy hard. Users are going to want to subscribe to different models for different things, and plug those models into whatever they're using. Everyone is going to support it, and to make it work there needs to be data exchange. Companies that don't support it to try and keep the data walled are going to hemorrhage customers.

In my experience they could reliably cut out the recruiter and hiring manager interviews.
That's not crazy. Some of these are probably what 30 minutes? Tech interviews 60 mins? So what, five hours?

Remember when on-site interviews meant an hour total commute plus say six hours of total interview plus lunch event. Some high demand companies put candidates through more than one round of that. Not to mention if you were flying from out of town... I remember a friend who interviewed with Google and got stuck in SF for three weeks due to snow storms on the east coast and got fired from Accenture as a result.

The article itself was a bit too holier-than-thou for me but I want more robotics content here on HN so let's hijack this thread and share robotics passion!!

My own shitty first foray into robotics is an RPi that I can talk to [2].

If you didn't see "the coolest robot I've ever built" you gotta watch that... so inspiring [3]

Latent Space has a robotics demo day coming up, pretty curious to see what comes out of that [4]

Some stream-of-conscious thoughts about why I'm drawn to robotics:

* The maker / hacker / homebrew communities that are basically just using robots to express art. Maker Faire, Burning Man, etc.

* The satisfaction of writing code and seeing something physical happen. Last week I was trying to figure out how to get a shitty third party Amazon robot hat [5] to actually do something useful so I was iterating through the GPIOs and I somehow made it actually smoke. I'm weirdly proud of messing up so badly that my hardware actually smoked!

* The joy of demystifying hardware and learning all the layers of abstraction just within hardware

> You’re socializing around your wife being abusive.

Not at all, for all they know you're living some 1950s lifestyle where your wife has dinner on the table just as you get home, and it'll be cold if you're late. Or if they prefer, they can imagine you're a progressive modern father, going home to change diapers and help with bedtime. Or they can imagine you're deeply in love, and eager not to disappoint your best friend in the whole world.

There really is nothing abusive about a man saying he likes his wife to be happy. Making an effort to make the other person happy and them making an effort to make you happy is the whole point of a relationship, isn't it?
This hasn't been our experience. Our public school kids are learning things we never would have dreamed of at their age. I distinctly remember being surpised at the worksheets on platonic solids that my kindergartener was assigned.

Same with the </canvas> tag. Are these closing tags needed for some "reason"?
I suspect the second (and third) line is included by mistake. Also, if we are counting bytes, the closing pre tag is required and should be counted. The game also relies on filtering out non-arrow key presses but this code isn't compressed or counted at all. The instruction "Do not press any other keys" seems superfluous with the extra onkeydown code added.

Why was this code and a lot of similar code posted to github only 2 hours ago?
Respect for citations. I'll read into this over the next few days.

I tend to treat papers as disinteresting until someone has asked me to tear a new hole in one (I can only really do that mathematically) or they have been reproduced. Decreases cognitive load when someone says "check this out".
"Swift for Tensorflow" never had any real backing apart from the announcement though.
Here's the abstract of the actual paper: https://pubmed.ncbi.nlm.nih.gov/38277296

> "Conclusions: The modern 'epidemic level' of advanced dementias was not described among ancient Greco-Roman elderly. The possible emergence of advanced ADRD in the Roman era may be associated with environmental factors of air pollution and increased exposure to lead. Further historical analysis may formulate critical hypotheses about the modernity of high ADRD prevalence."

Air pollution has near-zero explanatory power, though. See: "Global, regional, and national burden of Alzheimer's disease and other dementias, 1990–2019" at: https://www.frontiersin.org/articles/10.3389/fnagi.2022.9374...

"High-income North America" has the highest age-standardized incidence rate, whereas smog-shrouded South Asia has the lowest. East Asia, infamous for industrial and urban air pollution, is also fairly low on the list. From this data, there's apparently zero correlation between pollution and incidence rate.
True. But everything is trivia at a point.
Anything an iPad can’t do ?
I don't have to be in the business or habit of making laughably naive or galaxy-brain futurist predictions to acknowledge that habitable square-footage of land available to occupy is for all intents and purposes fixed. I'm not making any predictions, just noting that if we're growing above replacement rate indefinitely we will eventually run out of space barring eventual expansions off the planet. Even if every city on earth became as dense as Tokyo, even if we created all food production in sunless underground bunkers or skyscraper food farms, even if all nutrition becomes paste from compostable tubes, a society that inherently requires population growth indefinitely to function effectively has to get off-planet at some point.

This is especially true if you value (as I certainly do) the ongoing existence of land not just for farming and habitation but for the diverse ecologies of flora and fauna to continue to exist. I'm certainly more pessimistic than optimistic about how the rest of the natural world would fare in the next 150 years if we continue on as we have been.

But honestly, this to me is a sideshow: given our ability to produce efficiently and often autonomously, we shouldn't require a reliance on constant population growth to function effectively. Maybe that's where I'm being laughably naive.
This seems useful, thanks!
I didn't know that. I self host this on my own hardware in my office. If I wanted encryption at rest, I would just do it at the hard disk level I suppose.
When was that?

The law was changed from 2022 (I delayed starting my divorce proceedings by a few months to benefit from it) and we now have no-fault divorce. Essentially, all it needs is for one party to want to divorce and the a certain lapse of time after you married. The only grounds for opposing it are very narrows ones like jurisdiction.

The divorce case is separate from those over money and children which are also optional. You can just have informal agreements over both unless someone wants to go to court. That is why I spent very little time in court - in fact the divorce itself happened with need to attend hearings with the application made through the family court website.

Even before the change judges would try and find for an allegation of a fault (usually "unreasonable behaviour") and most lawyers advised clients not to contest divorces. One lawyer I consulted told me that in the previous 20 years he dealt with one contested divorce (contesting the end of the marriage that is, obviously going to court over child and financial arrangements is common).
I don't use autofill precisely because I have no insight into the algorithm behind it. I suspect it's very "stupid," but I don't know exactly how stupid it is.

It sounds like he didn't realize or notice that autofill was using adjacent cells (from other countries, in this instance). That behavior would shock me as well. I thought autofill only took columns of data into account.
Exactly! Very well explained.

But:

>MIT license still applies to the old code that did not change, from the point of view of a recipient of the combination, the results looks like a relicense.

That's again not true, you cannot delete the MIT license from that file, it's not important if you changed it, the original license is still there plus your license that don't contradicts the MIT license like "our license allows to delete all prior licenses" yes your added code is exclusively under your license but the whole file is MIT+ that was partially confirmed with the BSD and AT&T lawsuit (when AT&T took BSD code deleted the license and lost because AT&T "stole" more code as Berkley hmmm f're'e-licensed ;)

Taking off my devil's advocate hat for a moment - I disagree here. Many places in the world already redefine "factual information" with their own definitions that are based on e.g. their political or cultural views. Pretending it doesn't happen is not a satisfactory choice for me.

My play on being a devil's advocate is exactly going along this line - if we lose a part of the ability to convey facts because we lose an ability to read, then where exactly does this lead us to?

Even when they step away from Markdown, like for example the canvas feature (https://obsidian.md/canvas), they make sure to build it on top of JSON files instead of inventing a more proprietary format.

Does any of the competition use it? Not that I'm aware of. If Obsidian disappeared tomorrow, could anyone reasonably replicate it? Yes.

If you don't want to pay for sync, you have other options. If you want to publish your notes, you have other options. Technically you need a subscription to use it for commercial purposes, but they have no way of enforcing that, plus there's a carve out for freelancers and for those like me working for NGOs.

The point I'm trying to make is that not only are they user-funded, but all of their revenue comes from the most optional subscriptions you're gonna find in a for-profit product.
That's why I'm doing it in their stead - see the sibling comment.

"Do you feel like you’ve accomplished more than your peers? Led a more fulfilling and liberating life that allowed you to focus on yourselves? Or did that get old past age 40?"

I often feel that I did not manage to accomplish enough, personally. But:

- I know people who are immensely more affluent than me (high school fellows) who did not have any child, either, and did not need to work.
For me they accomplished even less than me.

- On the other hand, both my sister (who is 3 years older and has a son) and another friend of mine (former colleague) I would say made good use of their time and resources, because they lived what to me looks like a full life, managed to pursuit their interests, cultivate hobbies etc... and also raised a decent human adult on top, which is quite an achievement in itself.

What I am trying to say is "if I had won scientific or sport prizes or written a successful book... maybe I could say this would have been impossible if I had to take care of one (or more probably more than one) child".
And I cannot even say that I decided to not have children because I was focused on winning a Nobel (or developing my startup, or become a renowned martial artist...) and yet EVEN WITHOUT THE CHILD I failed for some other reason.

I have a normal life, some stuff I did may seem huge to others (assuming they share some of my interests) but while I can dream of having the money of my former schoolmate and say "boy, what I could have done if I were in his place" I am pretty sure that nobody is thinking "wow, if I had lived a childen-free adulthood like Pamar...".

I am not regretting it (maybe I'll soon do when it is time to retire, will keep you posted) but I would never say to anyone "if you want to live your life to the fullest, like me, forget having children", either.

The most frequent ending in the card game I mentioned is that as soon as it becomes apparent that one player will lose, they take everyone else with them.

> The West has pretty unilaterally proclaimed Ukraine to be the morally right side fighting for its freedom and that the West stands besides it in its rightful cause.

I think that’s essentially true in Europe (modulo Hungary, maybe), but it’s somewhat more ambivalent in the US; the presumptive Republican candidate for president is all but aligning with Russia on this one.

To some extent this is probably to be expected; Putin has designs on EU states, particularly Poland, as a next step (you could question how realistic a Russian attack on Poland actually would be, but that does seem to be Putin’s thinking), whereas for the US, the consequences of Ukrainian defeat, while fairly dire, would be more nebulous.
I feel like if you believe my conclusion was that "Julia is faster" then you are missing the point.

The point is that the original blogs claims of "Mojo is faster" isn't right - it's comparing different programs. That implementation in Mojo is faster than Needletail - but that doesn't say very much and I prove it by also beating Needletail in Julia by using the same algorithm as Mojo does. So it's the algorithm. Not Mojo. Not Julia.

Also, did you even read my discussion on how much a parser ought to validate? Your resume is completely missing the point.

The headline isn't blaming Excel. "Undisclosed tinkering in Excel" is not far from the accurate headline: "Misuse of commonly-used Excel tool..."

The interesting thing is that a supposedly sophisticated person was using an unsophisticated tool and then relying on the data it produced. Failing to mention "Excel" in this case is doing a disservice to the thrust of the problem.
The challenge is twofold on “elite” private trackers:

That's what people say right before the exponential function (or rather, X^n) elipses them

"Sure, the machines can do X really well, but what about Y"

Y is just X with more variables. The machines will be able to do better than 95% of humans in a couple years, and then eventually better than all humans. But doing better than 95% already means they will be preferred everywhere.

And the swarms is the key!
They actually do not hide the main reason and state it first:
"If we start paying everyone the highest wage our compensation costs would increase greatly, we can hire fewer people, and we would get less results."
That's why I like their approach and communication. As a Ukrainian, I would be happy to work for CA salary here, but I do understand that a good local market rate is enough for me if the job is great.

EDIT: and one more thing to add here: as an employer, you usually prefer to hire people whose motivation is not only money. You want to work with people who like the job and their colleagues. The current market practice is to pay local rates. Thus any company that pays much more, has to address the challenge of filtering out people with "incorrect" motivation.
