i use yi home camera (4 pack on amazon for $72 currently) which runs over wifi and firmware via https://github.com/roleoroleo/yi-hack-Allwinner-v2. this bypasses the app and internet connection entirely. you will need some microSD cards to flash and run the cameras.

this exposes RTSP/ONVIF and also allows for local motion detection and recording capabilities.

i also use https://www.scrypted.app/ to handle MQTT for motion detection events from the camera and restream to apple home to take advantage of notifications on my phone, remote streaming, etc.

this works fairly well, the downsides are that the install process is probably more involved than it should be, and the stand it comes with is just /ok/ but the mounting bracket is such that you can 3d print your own fairly easily. 1080 stream quality is good enough tho i'm sure there are better quality cameras on the market.
I discount the early days because I don't think most professionals would rely on a language pre-1.0 that advertises it will stabilize at 1.0, so regardless of whether it spends 6 months or 10 years pre-1.0, with regard to wider adoption you'll only be able to make limited inferences about what that period means.

For example, you say 17 years, but it was a side project for the first four of those, and was only publicly announced as Rust from 2010 on from what I can find (given there's no way my memory is that good), but the following two announcements back that up.[1][2] If it's not really public or being advertised, I'm not sure how that can count towards adoption over time. Additionally, if it's advertised but with the caveat that it's pre-release and just for playing with as a proof of concept, should that count towards the adoption timeline? Counting periods when people were specifically warded off in a project's lifetime also seems odd to me, but your assessment would also use that as an indicator of what it's achieved over time.

I wouldn't say a novel languished in obscurity for a decade just because the author mentioned they were working on it at some point, I would assess it from the point it was released as a complete work and presented to people as a finalized product they could read expecting a full story.

Prigozhin, audio statement at 00:31 BST, stating that Gerasimov "gave an order for planes to bomb moving Wagner columns". It is unclear if these columns exist in reality:

"Just now, the Head of General staff gave the order to raise planes and open fire at columns moving through civilian cars, through trucks. He doesn’t care whom to kill. They’ve been killing own civilians for 1,5 years now instead of fighting with the enemy.

I want to say thank you to the pilots who, as it just became known, refused to obey criminal orders."

Interesting. I just got finished working on some JavaScript to auto detect two-finger trackpad scroll vs a physical mousewheel and wondered why this kind of thing isn’t built into the OS.
My fascination goes to the way the content of the book is shared. Normally the unwashed masses would only be allowed to see a picture of the cover with a comment about the binding. Today it is different, we get selfies that show us, be it at unreadable distance, the inside of the book. I feel like I've seen an exposed ankle in the Victorian age, improperly exposed to something.

Is this a joke? I keep seeing this sentiment on this comment section but this is the complete opposite of my experience in Europe ( don't live there anymore though). Maybe it was just France, but every single inconsequential start up was labelled as the next Google and every city was the new SV. every tiny corporation had to have its army of "cadres" and European businesses' love for countless "initiatives" , buzzwords, blockchain, greenwashing... And so on would make American big tech look downright bullshit free in comparison.

I'm not American and even then it left me with a weird feeling of little man syndrome.
seems doubtful that James Cameron would care much about promoting a 30 year old movie that was widely rumored as a vehicle for him to get studio funding for his deep sea explorations (ie not clear he has much attachment to it).

Even strictly monetarily, spending 5 minutes on avatar 3 would probably be a much better return in terms of time spent : money earned.
The link for "Connections" (I've been calling them geo-graphs or network maps) seems to be broken, which is a shame. I've had a hard time finding good libraries for them, and they're hard to get right for a few reasons:

- if you zoom out to show the world, map projections wrap around the antimeridian (e.g. you turn right at Kamchatka, loop around and hit Alaska.) if you want your edges to wrap (i.e. follow a great arc) rather than taking the long way around (i.e. drawing a line all through Europe and Asia), you have to do spherical math.

- if you want a multigraph (multiple edges between any pair of nodes), you need to have a way for those edges to "curve" rather than following a straight path (great arc.) this makes the math much more complicated, especially keeping numerical stability and accounting for coordinate singularities.

- now imagine all the fiddly bits of making the arrowheads touch the nodes at the right place, scale in width properly, etc. if you're really committed, you'll use lat/lon for every vertex of every poly you render. if not, there will be distortions. it's a trade-off.

- now imagine updating all of that while panning and zooming, and keeping it efficient and smooth.

I made a component for this, I'll try to open-source it, but I'm curious how other people have tackled the same issue. Did I just over-engineer the hell out of it doing spherical trig, vector math and iterative methods, or is it plain hard?
Honestly, at this point I've given up on worrying about humans surviving. Our "leaders" have made it pretty clear that "long-term survival" is just not on their agenda, and we've allowed them to amass enough "wealth", "power", and weapons to make changing their minds pretty much impossible. What I worry about now, more than anything else, is that humanity has reached a level of destructiveness that we may trigger something literally catastrophic to this planet's ability to support life at all. What an incredible loss that would be.
You need to provide context around your role because;

If you are an engineering manager than it is probably expected that you attend meetings most of your time spend and you shouldn't be wired in to write code as is expected from an IC.

If you are an IC, escalate to your manager. However, if those meetings are with your direct team to discuss product roadmap, PR reviews, solution design, sprint planning, epic grooming, etc, then your manager will probably tell you that you should attend those meetings.
> Slotmap uses unsafe everywhere, it's a memory usage pattern not supported by the borrow checker.

Author of slotmap here. This is patently false.

Yes, the slotmap crate uses a lot of unsafe to squeeze out maximum performance. But it is not 'a memory usage pattern not supported by the borrow checker'. You can absolutely write a crate with an API identical to slotmap without using unsafe.
Pretty dramatic, it didn't even slow down despite the clear warning sign before the also clear stop sign itself.

I'm guessing those sites probably ruined their reputation by selling out their users, refusing to listen to them and belittling their genuine concerns about UX and API access.
Totally an armchair opinion, but I think Prigozhin is a toast and he knows it. He cannot fight (troops hated, plus ranks decimated in Bakhmut) and cannot hide (no one will take him). He may be just trying to go down with a bang. My 2c.

You're looking at it myopically as well.

JS has this semantic and the interfaces are designed with that in mind.

Take C# for example. There is a List<T>.ForEach() function that passes the value to the delegate. Fine. But what if I require the index as well? I can't use List<T>.ForEach() in that case, because ignoring extra arguments is not part of C# function call semantics.

The interface of map() has been designed to be as flexible as possible to cover use cases outside of just passing the current value. This matches perfectly with JS function call semantics that allow any number of arguments by default.

Why doesn't parseInt() *always* require two parameters? Why is one design decision "strange and unique" (e.g. map() passing 3 arguments) while the other (parseInt() accepting one or two arguments) is perfectly fine? I also would be careful with citing the STL as being sound when it comes its interface design :)

JS is different from other languages - big whoop. The same complaints about seemingly strange design decisions can be made for any sufficiently old and widespread language - JS isn't unique in this regard.

There actually annoying strangeness in other things, e.g. confusing type conversions in places (e.g. ("" == false) === true; [1, 2, 3] + [4, 5, 6] === "1,2,34,5,6"), which is why "==" should never be used if you want to retain your sanity.

The interfaces and standard functions, however, are as offensive or inoffensive as those in most other languages.
When your job consists of not being 'a lazy idiot', being one is nothing short of bad faith behaviour.
It’s self reinforcing. Other people spent more than 4 hours on it and lied, so their expectation of what can be achieved in 4 hours is warped. It’s really just a way of selecting for liars, although that goes for most interview tactics.
I keep harping on Visual Studio, but I learned programming with Borland Turbo Pascal (and later Turbo C/C++) on a 4.77MHz machine with 512k memory.
It was orders of magnitude more responsive than VS on my current 16 core 3.5GHz 128GB machine.

The only exceptions are: 1) the actual build, which is faster on the modern machine, but only for a large number of source files and 2) reading and writing files - a floppy disk cannot beat an nvme drive of course.

What’s the advantage of DC? You presumably still need to step down from high voltage or you end up with expensive thick wiring to avoid resistive losses.
No..

SpaceX funding comes from the members of ESA. The member countries are proportionally awarded contracts developing things for ESA in return.
Especially when:

1) The "revenge" crime involves intruding upon accounts maintained by third parties -- in this case, cell carriers, Google, and Dropbox.

2) The theft of IP was suspected, not proven, and accessing those accounts would, at best, only confirm that it had occurred.
The key word is "repeatedly" - the issue isn't just one comment, it's that your account has a pattern of commenting in the flamewar style, which I suppose could be described as the popular internet commenting style that combines snark, swipes, name-calling, and tropes with indignant, grandiose rhetoric. Your account has been posting a ton of these - here are a few examples I just randomly picked out:

I don't want to ban you, so if you'd please review https://news.ycombinator.com/newsguidelines.html and recalibrate, we'd appreciate it.
No. They just need to award contracts to companies in the member countries. It creates plenty of jobs.

Regardless of whether wages match inflation completely or how long they take to do so, the fact is that if solar panels cost the same in dollars as they did 10 years ago, the average person's wage buys more of them.

You could counter-argue that other things gone up by so much that despite this, people have less money to spare for solar panels. But given that solar panels are competing with some of those things, importantly fossil fuels, it's still important to be clear that they are getting cheaper - as the trend continues a solar panel pays for itself more and more quickly.

We were recommended Breville. They are more on the pricey end. But we did get them second hand via FB marketplace.
> Your attitude of nobody is allowed to show any pride in anything related to fossil fuels and its general bad and shouldn't be done is simply no way to go forward.

Not saying it should not be done at all. Reusable rockets would be nice, if they were used like the non reusable ones (i.e. rarely). But that's not how technology works: if the technology becomes cheaper, we don't use the same amount for cheaper; we use more.

Can you seriously look at SpaceX and think that they just want to send a few rockets per year, for a fraction of the cost?

> Just like with aviation we need to consider what regulation we want to apply to these things.

That's the thing: if you regulate the rockets market such that it does not start polluting orders of magnitudes more, then it is not a viable market.

> Earth observation sat measure climate change. [...] GPS is a vital technology for so many industries.

We did not need SpaceX for that. Compared to Starlink, Copernicus and all the GNSS satellites (GPS, Galileo, Glonass, ...) just don't count. GPS is something like 30 satellites. Starlink wants to send tens of thousands.

Well that was a dumb thing to do! You could of flashed it with OpenWrt and had a dam good router.
Takehomes have been ruined as a concept by companies that spam them out before applying a first pass.

I’ve passed interviews at demanding companies like hedge funds, Google, Facebook, Snap. Not once have I “passed” a take home interview even when I know I got the solution correct. Sorry, but I refuse to do them now. Companies need to be able to show a token investment in time with an actual engineer interviewing me for me to be convinced they are actually considering me as a candidate and didn’t just send me a takehome link without any due diligence because it costs them nothing to do so.
Unfortunately, at this point some of the slow layers are in hardware, or immediately adjacent to it. For example, AFAIR[0], the time between your keyboard registering a press, and the corresponding event reaching the application, is already counted in milliseconds and can become perceptible. Even assuming the app processes it instantly, that's just half of the I/O loop. The other half, that is changing something on display, involves digging through GUI abstraction layers, compositor, possibly waiting on GPU a bit, and then... these days, displays themselves tend to introduce single-digit millisecond lags due to the time it takes to flip a pixel, and buffering added to mask it.

These are things we're unlikely to get back (and by themselves already make typical PC stacks unable to deliver smooth hand-writing experience - Microsoft Research had a good demo some time ago, showing that you need to get to single-digit milliseconds on the round-trip between touch event and display update, for it to feel like manipulating a physical thing vs. having it attached to your finger on a rubber band). Win2K on a hardware from that era is going to remain snappier than modern computers for that reason alone. But that only underscores the need to make the userspace software part leaner.

> The EU or US could just decide to pay for it.

That sounds logistically very difficult. The government would need to decide _which_ standards are worth paying for. You certainly couldn't have everyone who wants to just bill the government for however much they decide their standard "costs" to develop.

Unless it's a standard that you need to follow by law, it doesn't make sense for the government to be in charge of making it public.
> Economic feasibility due to engineering problems.

The question then becomes, who's actually saying this? It's certainly not real engineers. In fact, real engineers have pointed out that it is much cheaper to distribute hydrogen than electricity:

>BRINK: How do you move the hydrogen from the solar farms?

> AD VAN WIJK: By pipeline. That’s the interesting thing: It is about 10 times cheaper to transport energy by a hydrogen pipeline than by an electric cable. That makes it possible to transport electricity very cheaply from somewhere like North Africa to the demand centers in Europe, for example.

https://www.brinknews.com/could-hydrogen-replace-the-need-fo...

And all of this is happening under the auspices of effectively free hydrogen due to a combination of subsidies and cost reduction. This should really raise the question of how any of the alternative ideas are going to compete with this, not how whether this idea can work.
