Is remote sensing through 5G antennas possible?
Many here might already know that the controversial new 802.11bf wifi standard, set to be introduced in 2024, will enable active "remote monitoring" of movements or objects through the microwaves the devices themselves emit. Microwave sensing works similar to the more well known radar or ultrasound.

I'm trying to find out if remote sensing/monitoring is something that's in practice possible with the 5G antennas that are installed everywhere now. I've searched for papers but might not know the exact terminology, so I didn't find anything. I know it's theoretically possible and what made me wonder is that with the new wifi standard they're shortening the wavelength specifically to get higher resolution imagery. I've seen the argument brought up many times that 5G doesn't bring much speed advantages and that many people don't understand why they increased the frequency so much, which creates some problems (like shorter working distance, for example). Now maybe I'm going full conspiracy here, but it would make perfect sense to do this if one of the goals were monitoring the movement of EVERYTHING in the range of the mobile network antennas. Is this a thing that could practically be done? Feel free to tell me I'm crazy, but please do include an explanation with a source for why or why not.

What motivates you the most - money or alignment with your natural interests? Look around the job market and pick a position to focus on that strikes a reasonable balance between the two.

Embedded systems engineers command great salaries, so do full stack engineers. I wouldn't recommend game development if you want to continue enjoying it as a hobby, the industry notoriously burns people out quickly.

Once you've decided on a position to focus on, search through a bunch of job postings and take notes on the skills and technologies that employers are looking for. Study those skills and technologies by reading books and working on toy problems that interest you. Putting together an open source project is a great way to demonstrate these skills to potential employers, but definitely not necessary. Be on the look-out for jobs and employers that seem particularly interesting to you.

When you feel reasonably in touch with the basics and fundamentals, start applying for positions. Start out with employers and positions that you don't particularly care for, use the interviews to practice your rhetoric and build your confidence.

Make sure to have trusted friends/coworkers/mentors in the field review your resume and give you feedback. I avoid listing any particular technologies on my resume, because sometimes they can box you in - but admittedly some employers will be looking for X Y & Z technology listed on your resume, so don't be afraid to make small tweaks for specific companies and positions you are really interested in. Don't be afraid to embellish your resume and work history - it's okay to say you led a team even if that responsibility was never formally acknowledged. Don't outright lie though, and be very prepared for interviewers to ask in depth questions about your prior experience - I usually bring a notepad with talking points to help me remember all the details of projects I've worked on. Don't be afraid to admit a lack of professional experience with some technology - having experience with such technology on personal projects can go a long way towards demonstrating aptitude.

Finally apply to those jobs and employers that stuck out to you - the ones you really wanted or were interested in learning more about. Try to give off a vibe of ambition and hunger to achieve, managers will pick up on those traits, whether consciously or subconsciously. Technologies come and go but soft skills are very important so feel free to mention that you're a great technical writer or that you are an excellent mediator of conflict, etc - it can help fill the gaps of experience or knowledge in a domain.

Most of all believe in yourself and your capacity to learn and grow - that will be the primary factor in your success.
Data formats like Parquet/Arrow and DataFusion are optimised for high speed read/write (and the processing) of large amounts of data, which is generally what you’re going to be using them for.

Additionally, as others have mentioned, clustered processing for larger-than-machine/ram datasets is a bit easier to manage compared to setting up a database cluster.

Another benefit is ephemeral-compute: we have Kubernetes cluster, and a particular message in a Kafka topic can kickstart a a spark job across several machines in the cluster (possibly causing auto scaling) which processes the x-TB’s of data it needs to, writes the results out and then finishes. Faster, cheaper and more suited than keeping a multi-node db cluster going.

Also lets us run non-SQL stages with less bottlenecks: bulk ML scoring, bulk data enrichment, etc.
Certainly we have been going along under an EUA, without individual prescriptions.

I'm just as ignorant as you, and your point about the flu shot is a good one. I'm not aware of a prescription being required for that.

But as I read the document, it implied that with a regular approval and without the EUA, a prescription would be required and so that was one of the reasons for renewing it.
If it ignores HDCP, doesn't that prevent you from using it to play Netflix and Amazon Prime content?
simple analogy was simple..

Would you prefer comparing it to gold ? Art ? collecting sneakers ? or Comic books ? how about buying land ?

Edit: I should probably clarify..People buy/collect lots of things in the _HOPE_ they'll increase in value. BTC and crypto in general is not unique in that regard.

What’s wrong with professionalization?
The other day I found an interesting webpage linked from https://news.ycombinator.com/item?id=28232716 that outlines the practical accessibility of hiring researchers for things. There are a lot of possibilities here: a domain expert could autonomously take the subject further, or they could provide targeted insights that factor in your strengths/areas of expertise, or they could even work with the original reporters (who likely have private access to a tonne more info, and might be willing to follow up with it further if independent funding is possible, etc).

(The thread the above comment is from was also very interesting too.)
So in this hypothetical is the person directing traffic completely oblivious to the existence of self driving cars? Pretty sure we can assume traffic cops in the future will be trained to deal with self driving cars and use only use gestures from a predefined list.
Surprised this is downvoted when it was exactly what the OP was asking for. Good job orange website.
Its quite possible we really underestimate the level to which state enterprise plays a role in innovation. Its sort of like we think "oh in the 80s sure but not anymore!". Ditto pharmaceutical "technology" with really heavy basic research funded by universities.

I have no idea where the line is though, and its hard to say what might've happened in a better "market".
ETL pipeline is a perfect fit for Datafusion and its distributed version Ballista. Personally, this is the main reason I am investing my time into Datafusion.
In that case, the alternative i that, if you finish something an hour before EOD, you go for a walk or watch some TV show. Then come back and push your code.
> There also seems to be an additional barrier of US carriers imminently requiring VoLTE, and in some cases only allowlisting a small number of models.

Is this all carriers, or just some? I know that AT&T is the main one since I'm affected by it (their whitelist arbitrarily removes my OnePlus 6 from being supported this February despite the phone supporting VoLTE), but I heard that other carriers such as T-Mobile are still working without VoLTE. Either way, the whole "requiring VoLTE" thing could even be a problem for some custom ROMs (not even GNU/Linux phones) since I believe VoLTE support is something that ROMs sometimes miss, which will be pretty bad. While I'm not a full "privacy" user (yet), I use custom ROMs for extending the lifetime of my phone and getting newer updates than I would on the stock ROM, and carrier limitations could seriously threaten a lot of things.

> Not really. L5 is impossible, period.

Agreed.

> L5 which means 100.000% covered, will not happen, but the PR people will continue to use the term.

Which is precisely why so many people are critical of the term "fully autonomous".

> 99.999% cases covered

What cases? The point is that edge cases are the issue with autonomous driving. I can fall asleep on a train or a plane because I know there is human conductor who can handle the edge cases. This doesn't exist with L4. Everything else that doesn't let me fall asleep (read a book, look at my phone, etc.) is only marginally better.

> assuming there was a way to safely stop.

That's a pretty damn strong assumption.
The "Concept" idea is very cool... seems like it would make it really easy to construct refinement types and build validation into the type system.

> I don't really have a point other than to say that resettling refugees isn't as simple as "oh just give them a place to sleep and some cash and the rest will take care of itself", like it's via osmosis or something that they inculcate the values and culture of the new "home" they find themselves in. This isn't software you can install, it's much harder than that.

Everyone understands that, including the Airbnb people. I don't think there's actually anybody mistaking the context as you're suggesting. Over a million poor immigrants - most of them de facto refugees trying to escape from very dangerous third world poverty in Latin America - enter the US every year with essentially nothing, looking to start a new life. Tens of millions of people from that context across the last 30 years alone. This is an old, understood, persistent process in the US.
>I am pretty sure Sputnik V is fine. It has been administered to tens of millions inside Russia itself. If there were massive problems with it, we would know by now.

No, we wouldn't. Because most of the Vaccine AEFI tracking is based on voluntary reporting, and is known to only report around 1% of the events.

Even if it was not the case, we wouldn't still know without a control group. Basically this is why systematic trials are done to measure these things.

So this logic does not absolve Sputnik vaccine, or any other current vaccines in use.

Hotel. I don't quite understand the point you're making.
The good thing with state innovation is that it doesn’t necessarily end up with the question: “and how do we make money from this?”, which too frequently is answered by “oh we’ll just sell people’s data”.
“The alternative to occupation would be a more complete destruction of the country.”

You seem to be conflating a theocratic regime being in charge with the bloodshed of war, or as you call it, occupation. A great many people died and were horribly injured throughout the 20 year war. But you think the wrong regime would have been a “more complete destruction?”
Having some very widely used things being 0 indexed, and others 1 indexed, kind of points to a problem in the language, regardless of if it's technically a language syntax issue:

At the end of the day you're still going to have a ton of time wasted by devs having to check, and there will be bugs eventually of things being not converted or double converted between the two index schemas
Yes, you are right. So either way, these vaccines has not passed through proper safety evaluation.

Just because something is not possible, does not make it any less required.
No different then 'collecting' funko pops, spoons, sneakers, comic books, and a host of other things and hoping they increase in value.
Flask was incredible and a joy to build with, but it's not the future. It's only the present in that so any legacy apps exist that use it and because people who don't knew better will likely still stumble upon it first and use it for their new project.

But we are at the point where async python has really taken off, as well as where the performance gains are just impossible to ignore except for apps thats are either dead-simple or that are super CPU-bound. And FastAPI is unquestionably leading the pack with regards to async frameworks, so it makes sense to target that. (Also, yes, he's the creator.)

(Additionally, FastAPI is using Starlette under-the-hood, which is built on ASGI, part of the point of which is to standardize async servers and frameworks to allow for wide compatibility. Anything that works on Starlette or any ASGI framework will work with FastAPI, and vice versa unless the component is tightly coupled to FastAPI-specific code.)

Which apparently failed quite dramatically for my interpreter since he still holds views that clash with the mean understanding of what's politically acceptable in the United States. Perhaps that's my fault. To that end, no I don't think everyone "understands" this.
Tons of games have ping systems that are comparable if not much more advanced. Dota 2 has had pinging since 2013 and expanded features like a chat wheel in 2017. Idk how patents work but it’s hard to believe EA gets to claim this as their thing when prior art exists
You are right. We do need systematic trials to confidently makes statements like the one I made. Thank you for pointing out the error in my logic.
YES! I still remember the earlier days of Google, when it was not only returning results, the results were a delight to click through. I genuinely felt happy using it. Infoseek was good in a way that it let you search within searched results, so you could filter down. Alta Vista was definitely larger, but Google was pure magic. Not only relevant but digs up interesting and rewarding well researched information sitting around in a little corner of a web.
The US didn't. The anti-US propagandists will lie and claim the US created the Taliban in the process of supporting the Mujahideen against the Soviets, which is a stretched fiction. Back in reality, there were and are many powerful regional factions in Afghanistan, many disparate groups of Mujahideen. The Taliban came into existence long after the Soviets left Afghanistan.

Datafusion, and Ballista by definition, also provides a Dataframe API that let's you construct queries programmatically. It also has preliminary support for UDFs.

We also have community members implementing Spark native executors using Datafusion, which showed significant speed improvements in the initial PoC.
I had no idea, fascinating! Is this because of uneven magnetic “hot spots” or something?

Show HN: Altilunium Hivemind
Interesting idea but there's a lot of edge cases to think through. Maybe this could be implemented with a custom front-end that interacts with the HN API?

HN is still working on rolling out some basic usability features such as pagination. Not to shoot down your idea, but realistically stuff like this won't make it into HN for a long time. And that might be a good thing - HN prides itself on relatively simple UX and fairly straightforward rules for ranking articles and comments (even though behind the scenes there is more sophistication, e.g. voting ring detection, etc).
I wonder how you go about proving to Airbnb that you are an Afghan refugee.
Oh yeah, the first paragraph is an absolute doozy:

'As I argued in part I, scientism—the view that all real knowledge is scientific knowledge—is either self-refuting or trivial. Moreover, consistently pursued, it leads to the “eliminative materialist” position that the human mind itself is a fiction—that there are no such things as thinking, perceiving, willing, desiring, and so forth. This position is not only incoherent, but undermines the very possibility of science itself—the very thing scientism claims to champion.'

It makes absolutely no logical sense that consistently pursuing scientific thought would only ever describe the human mind as a fiction. The author is a bizarre fantasist who not only doesn't understand science, he doesn't understand science itself or is deliberately mis-representing science as some kind of philosophy or religion that purports to offer "truth". i.e. quoting again:

'Hypnotized by the unparalleled predictive and technological successes of modern science, contemporary intellectuals infer that scientism must be true'

It's nonsense. Who are these contemporary intellectuals? Despite all these conservative think-tankers trying to conflate science with philosophy or religious pursuits, nobody expects science to deliver the truth, they expect it to deliver results. He can pray for some I guess.
>The beauty of science is that now that the vaccines are out there it becomes easier to independently access them and move our knowledge further in the right direction.

If 20k people are helped, and it also happens to benefit Airbnb, then that's fine by me.

If, on the other hand, Airbnb benefits from HURTING 20,000 people, then we would have a conversation.
True, if you build something inside a rackmount case then it can be whatever you want. However, from what I could tell empty rack mount case & rails are still a bit of a premium. Were you able to get rack mount case w/ rails at decent prices? Seems each one would have to be at least a 2U to fit a normal ATX PSU ( I guess you could use an ITX or small PSU but those can be more expensive for the same wattage).

How did you handle the system & case fans? Did you rack cases have the standard fans and were you able to configure those to be slow/quiet?
Look at the miracle of the covid mRNA vaccines. Moderna was state sponsored years ago to develop the tech.
The real interesting thing in fact is that I did not even conclude issues that you meant. At the moment I focused only on ml/dl algorithm and its ‚accuracy’, but its center of gravity lays stricly in form of gathered dataset. It gives me that feeling that I am missing something right now and it wont be usable on production level. Indicating what set you could build from predicted bricks should not be hard because as far as I know there are official APIs which allows you to gather specific information about each set. Thank you for explaining part of your side project, it was really interesting!

> Most of the commercial value is achieved at Level 4.

There are two markets:

- Level 4 driverless taxis (~$500B market)

- Level 5 driverless cars for every human being (~$10T+ market)

So, most of the commercial value for Uber, Lyft, etc. is from L4, but L5 is where the most overall economic value is.

But L4 has to be achieved in all locations, otherwise that TAM is highly variable.
If you're not interested in having a rational discussion about it, you can just say so.
In the automotive industry we called this "level 2.999." I've moved on from automotive now, but in my experience nearly all of the new vehicle features in development, big or small, are developed at that level.
