The first time I witnessed a vectored model rocket, was in 1996.

It was launched at the 5th Annual Scottish International Rocket Weekend, in Kelburn Country Park, Largs, Scotland. [0]

I was 17 years old and a member of the Paisley Rocketeer's Society [1] - one of the oldest model rocket clubs in the world, led by the late John Stewart.

Gyroc 1's vectoring was accomplished by controlling a model rocket engine by way of 2 axes controlled by a gyroscope. Subsequent Gyrocs have been made and flown. [2] (Note: the article states 1995 but the 5th IRW was in 1996 ;) )

The model rocket launched to a height of about 1-2 metres, and only managed to hover for a couple of seconds before the model rocket engine was spent, but at the time it was a glorious flight.

Windows CE was provided as a sort of alternative API for development. Part of the reason some developers stayed away from the Saturn was because it was difficult to develop for; another was that Windows CE could make it easier to port games to the system from PC. However, the 'standard' development toolset for Dreamcast was usable enough that few people bothered making games on top of Windows CE.

Huh, as another commenter said, some people are just more susceptible than others but I've worn headphones for many hours a day to no ill effect. There should be no clamping pressure on the ears, the weight should be on the headband. Might be worth looking at different options. Over-ear vs On-ear can make a difference.
Surely the reduction in land used must have a significant environmental impact. For the crops in question, you are talking about the ability to have a 2-acre building surrounded by a 718 acre nature reserve to get the same results as a 720 acre monocrop. I find it hard to believe that the long-term environmental impact of installing equipment would actually outweigh preserving 99.7% of the land.
> And having two completely separate internets (IPv6 and IPv4) forever isn't a wasteful burden?

Your proposal would force maintaining IPv4 for longer and in more networks: every IPv6 router would have to have IPv4 connectivity and probably a routeable IPv4 address, so it wouldn't even solve the address exhaustion problem for long (perhaps not even at all).

> Not requiring backwards compatibility in IPv6 guaranteed that IPv4 would be around forever. IPv4 is never, ever going away because of this.

IPv4 has already been eliminated from newer edge networks, and for those networks the vast majority of upstream traffic is IPv6. No doubt those networks will have to maintain 464XLAT for a long time as the long tail of upstream sites that are only v4-accessible, but they'll be able to have a smaller and smaller pool of 464XLAT servers and outsource the v4 connectivity support further and further upstream (just as with Usenet), until eventually v4 connectivity becomes a paid add-on and then goes away entirely. Home routers for use with PCs will probably have to offer 4over6 for a long time, because it's hard for an ISP to be confident all their users are up to date, but that doesn't actually reduce the benefits that much (all your internal network management can still be v6, only the little home user LANs are v4), and organisations that manage all their endpoint devices don't even need that much.
I think that's a neat concept. I feel it can also be destructive. It seems like a lot of modern problems will never be solved until decide to move on. Whole wars have been fought for what happened hundreds of years ago because people won't move on to a new world where people are people rather than this culture or that culture and they're "so different". History is great and all but you have to put it into perspective or old wounds will never heal.
What's the best strategy when playing HORSE? (basketball)
I imagine companies that choose to do a split or go back to the office are doing so to justify an existing capital investment they've already made. At my 2k-person company there is overwhelming support to keep the office open as a place to socialize than for real productivity. Seems to me it might be cheaper to just give employees a small budget for recreation than to invest in facilities, security, food, and A/V so people can escape their kids every now and then.
Does anyone here already tried ANC on these new true wireless earbuds ? Does a better better isolation always imply to a better sound quality ?
Might try different pairs. My cans for recording are HD180s, pretty standard and they really squeese your head.

My bose quiet comfort are comfortable for maybe an hour or two before i even notice I am wearing them.

From there small in ear with noise cancelling can be good

If your ears stick out or are bigger you should really go to a best buy or music shop or whatever and try on cans until you find ones that fit

Yes you are correct, root cause != person to blame. But....

That is such a over simplification and ignores a lot, most, of the issues in the GFC.

* Regulatory capture

* Illegal behaviour by trusted actors (chiefly banks)

* Corrupt judges

* Carelessness by trusted agencies e.g., credit rating agencies

Long long list of the collection of failures in the international financial system in general and American civil society in particular.
I really appreciate this list. It's cool to see how people work, and I'm sure the folks building the services you're using appreciate the kind words.

I also had kind of a strange reaction to it, which I tried to figure out, and I'll explain it in case it's at all representative of other reactions being posted here.

I think it's just kind of intimidating to read a list of SaaS someone else uses. After reading the whole list, in the back of my head I'm imagining the burden of learning all of these all at once, of managing a dozen new passwords and payments I'm not currently managing, etc, and I'm not imagining an improvement to my own workflow because my work doesn't match yours.

It's easy to imagine getting zero or negative value out of any SaaS if it's not solving a problem I personally have.

But on the other hand it's hard to imagine getting less than 12/mo for any service that is doing something for me. And it's hard to imagine that a 3 person team mistakenly believes they like some service they're using.

So I'll skip the judgment about how you're spending money on improving your work environment and say thanks for the post.
> Your empathy is appreciated but unaccepted, this is not the goal. Again, the goal is to debate a point and find a correct answer.

Ironically but very relevantly to this conversation, it seems we disagree on the goal. :)
The Remarkable tablet!

It has completely replaced paper for me. Diagraming, reading, etc. I waited 5 months for the device, and it was definitely worth the wait.
There are package-free / fully reusable packaging grocery stores popping up. I really think its something that could become the norm with pretty little pain for people. Worth looking to see if there is one in your area to push the death of single-use plastics along.
That's an absolutely feature. Road noise is a big fatigue on bikes and older loud cars.
For anyone interested in neural nets Backgammon makes a fascinating example. Essentially, AI computes the value of each position. Like a dome roof, the entire height could be off by a fraction of a percent, but all that matters is the relative values of the possible next moves. These valuations converge much faster than the overall function.

> I'm pretty sure you could also maintain a temp table and use some kind of "insert...where...returning" construct to squeeze that into a recursive query.

I'm not sure if this is possible in SQLite, as far as I know the WITH clause is limited to SELECT statements.

> Are they actually efficient in sqlite even for trees?

Recursive common table expressions work by adding returned rows to a queue and then performing the recursive select statement independently on each row in the queue until it's empty.

You can use WITH RECURSIVE to traverse a tree by adding the root node to the queue and recursively visiting adjacent rows until the queue is empty. This works correctly and quickly because trees have only a single path between nodes. If you try the same query on a DAG though it will return every path to a given node, you then have to perform a GROUP BY to find the shortest path outside of the recursive query. In the worst case, if you have a graph with many paths between nodes, this method is exponentially slower than a standard BFS.
Taskord Changelog – v1.0.3 – Dec 27
It's interesting how this varies between manufacturers, even though they're all using the same sensors.

I've used a Nissan SUV and a Honda car with the ACC/LKAS systems. The Nissan has automatic steering more than just lane keep 'assist' - there's a somewhat sharp curve on a highway where the Nissan takes it well, but the Honda has limited steering torque available and just gives up + turns off LKAS in the middle - which is a bit scary, especially since the audio alert is either quiet or not always triggered.

On the other hand, the Nissan has the same issue with merging cars that you mention, but the Honda seems to have an uncanny ability to recognize it and slow down / make space, just like a human would. Maybe their camera system detects blinkers, or their radar is more sophisticated? I haven't driven it enough to get a lot of insight on this.

Overall it seems like all three systems are just bad enough to require constant attention - each has weaknesses that make it unreliable in the right scenario, and other manufacturers have those specific issues resolved but have their own issues. Except maybe Tesla.

Nissan has had this since 2018, I wonder how their latest implementation is doing. And also the ones from more expensive brands. Honda's 2020 systems also have low speed follow which works for city driving where you come to complete stops, but my car is a manual transmission so I don't have that feature to try.
I get 'vertigo' from ANC headphones. This sounds like my personal hell
The mathematical treatment of the underlying 4-parameter curve family is coming soonish; this blog focuses on the UX, which I think is also a very interesting and challenging problem.
Amway is weird. It's almost a quasi-religious cult.
I'll give an example to illustrate.

Situation: my software service stops working because it ran out of disk space.

Insufficient focus on root cause: I add more disk, do nothing else, and assume it's solved.

Excessive focus on root cause only: I investigate, find there's a leak where old data never gets deleted, call it the root cause, fix the leak, and do nothing else.

Balanced approach: I fix the leak AND stop running at such tight margins (allocate breathing room) AND add automated monitoring for low disk space.

The lesson to look for the root cause is valuable. Without it, disk space fills up rapidly and my other measures to insulate against that can only go so far. But if it's all I do, that's also bad.
I love the two-finger point.
None.

But seems like the trend of the last 10 years is to rewrite every single already existing Unix tool in Rust or node.js. Throwing out code is more fun than reading man pages I guess.

This saddens me. It looks like the average dev in 2020 believes he needs to pollute his working environment with thousands of seemingly useless tools to be productive.

fzf, silver searcher, ripgrep, etc.

I will be downvoted to hell, because these people genuinely believe they need these tools, and will find whatever performance or feature argument to explain why. But from my experience, I am much faster at any command line task than pretty much anyone using these fancy stuff, even though I stick to bash, vim, and coreutils...

The inner image is just an image but there is a component around that. I am not a front end person and don’t have a theory but I’m also curious now.
If you are able to afford it, I've found the more expensive noise canceling headphones to be dramatically better, softer and more comfortable for long wearing. I'm def not an audiophile, so I'm more talking comfort than anything else... The one I've been really impressed with is the Bose Quietcomfort 35 II. They're usually $300 but often on sale on Amazon for $200.
The current crisis in cosmology and how we got here
I find the people who think there is such a thing as an American Nazi movement are the ones whose idea of what a Nazi is comes from Marvel comics' Hydra.

A simple question: have you actually read Mein Kampf or the Communist Manifesto?
Sure, but it’s a completely unsubstantiated leap to suggest that this means the store revenue will be ‘dropped’.

Both users and many developers benefit from the store for reasons already outlined in ways that the web can’t replicate.

It’s not going to be ‘dropped’ just because streaming games don’t fit the model.

I don’t know anything about payments or the EU regulations but it feels kind of stupid to not specify the maximum amount of time allowed? Is it just bad documentation or does that date/interval have to be secret for some reason?

Everyone and their grandmother uses the C Preprocessor. However comparatively few people have heard about its cousin m4 which was invented by the same people. m4 never caught on because it isn't very pleasant to use. I'm surprised no one here has mentioned it, since its existence is living proof of just how successful and amazing the C preprocessor is. https://wolfram.schneider.org/bsd/7thEdManVol2/m4/m4.pdf
I am happy for the the fact that lot of people have been lifted from poverty.

What I am not happy about is all of us, all 8 billion of us, being able to afford everything we can and hoard useless electronics and plastic doo-dads, waste a ton of resources and live an excessive life. But, "We in the west have it so they should also" is a controversial take on this.

We as Americans waste a lot of resources. That shouldn't be the role model for others.
A poster asked something similar on the What if you could do it all over thread. [0]

Although I don't know much about your life, I am going to venture a guess that if you were in this position in the first place, you are bound have marketable skills and are very privileged. Note that I am not doing the "but the kids in Africa" argument but its reverse. You have already won a lottery and can focus on the prize you did win instead of robbing yourself of happiness by looking at even larger jackpots. I am not saying that you are not allowed to be sad, rather just trying to wake you up to the insane bounty you do already have.

Doesn't it fill you with joy to know that you are leading a freer and more comfortable life than 99.999...% of people who ever lived? The quality of your life is already fundamentally equivalent to those wealthy people you torture yourself about. i.e. you can more or less afford to have a life rich in chosen experiences and organize it the way you want. You already have access to all the good things in life other than the sort of megalomania and diminishing return based entertainment that billionaires like to spend their time with.

By definition it will be hard to stop your feelings through rational argumentation. So what I'm saying is to just wake up to the things you have.

That does not ring true. Crusades were mostly forgotten until the rise of Arab and Turkish nationalisms. They were then appropriated into nationhood folklore.
> I mean, not finding a record in a database is not an error, nor is getting a response to a HTTP request with status code 3xx or a 404 or a 409.

But in some languages, exceptions would be used to handle these cases. Admittedly, those languages are usually higher level than C/C++ (but both Java and Python would probably find it common to handle a 3xx or a 404 or a missing row with an exception)

At a high level, I think the important thing is that funct() -> Result<T> and func() -> T that may throw/raise an exception are basically equivalent. Result may require slightly more explicitness at (at least) one call site, but ultimately both allow you to return a T, or report some non-T result, in a structured way. The only difference is that exceptions force you to handle the result explicitly (although that may just mean a single call to value! or VALUE_OR_DIE, or whatever the "get the T or segfault/panic" method is). In this way, I really do think checked exceptions are highly analogous to Result types.

Implementations may have different performance tradeoffs, but those aren't implicit in the choice of exception vs. result.
Recently I started a job that has me using a headset with ANC (active noise cancellation). It was OK for the first week or two but then I noticed my head hurt. My ears felt full and I had ringing in my ears that was quite loud. I have mild (self-diagnosed) tinnitus but this was beyond that by a significant amount.

I'm aware of how noise cancelling technology works it's by creating an opposing sound wave of equivalent energy to nullify the unwanted sound wave.

My theory is when I am off a call and I have the headset on my head with ANC enabled it's working to cancel the background noise. It's only needed on a call but it's obviously on all the time. These are not cheap headphones I've seen them for $300 so not cheap but I'm sure not the highest end.

I've tried taking them off, put around my neck, on my head between calls. But a few times I've fumbled them and hung up on someone or picked up before I was ready. My solution was to turn off ANC which made the sound clearer and my ears don't ring as bad as with ANC on.

My own anecdotal evidence but there is an obvious effect on my ears. I was about to go to the doctor the ringing was getting so bad.
When Tesla pops, it will potentially lose 80 or 90% of its values over a couple days/weeks. Even though that's only 2% of the SP500, it will trigger a panic sell for related companies in the same industry, and it might eventually become a macro indicator.
> the entire message you are delivering here is to attack America with this strawman and claim (now) that almost everyone else is governing better.

I am trying to help - you are perceiving that as an attack and you continue to incorrectly try and tell me how I think - an obvious impossibility.

> and claim (now) that almost everyone else is governing better.

Throughout this thread I talk about looking to countries that are doing things better, obviously not every country!

You choose to misrepresent a throwaway joke comment as having some deeper meaning: “What most every other country manages to do for breakfast” is an allusion to the now mostly obsolete habit of reading about international news in the morning paper, nothing nefarious.
AirPods Pro certainly has much better bass with ANC on, and I'd say overall sound quality too. It also sounds louder, although I'm not sure if that's just perceptual: higher sound levels are fine to me with ANC off, but are unbearably loud with it on. That's in both loud and quiet surroundings.
Ask HN: Giving new co-founder 40% equity at seed round?
I have a C-Corp and want to bring in a new 30-40% co-founder at a possible upcoming $5M valuation seed round.

The problem is, every scenario I look at ends up with him paying unaffordable taxes, even if he vests 10%/year -- he is just out of college. We have minimal cash and may not be able to restructure the shares before the seed round if it's expensive to do so. (The seed round isn't guaranteed but looks promising.)

I own 90% currently (RSUs reverse vesting), we have a 10% early investor (preferred stock), and our current legal fees are deferred until the seed round (would it be typical for them to do this restructure, even if the seed round isn't guaranteed?). Even then, our current valuation is about $1M based on the early investor, which would still impart some taxes (especially with reverse vesting).

With RSUs and options, I believe he'd have to pay for the stocks at the new $5M valuation. We could maybe buy back some of his shares to help pay the taxes, but I doubt investors would consider that good use of their money? Either way, I don't want to lead our new co-founder on if there's no way to structure this.

Would any of you have any idea how I might be able to make this work? Would be super appreciated. (He's been integral from the very beginning, which is why I wanted to give about equal equity instead of a seed-round-funded market salary.)
Got a kick out of seeing this post. If I am not leaping to the wrong conclusions from your user name, then I know who you are and I'm the original author of that backgammon game :). I worked with your Dad to publish it back in 1990 or 1991. And yes, we got complaints all the time about die rolls favoring the computer player. At least as of a few years ago you could still find some archived usenet threads where we tried to put those to rest by discussing the architectural features you alluded to, as well as publishing some multi-million roll statistical distributions. I recall that Joe Celko brought up the situation in one of his digressions on pseudo-randomness. Thanks for the walk down memory lane.

So, are these the numbers?

TBW is 600 TB, but you do 3TB/year across four disks, and I'll be generous and say you do .75/SSD/year.

so in 750 years you'll hit the rated TBW?

If you did a full 3TB/year on the one SSD, you hit it in 200 years?
