Yes of course.

There are different sensor sizes in cameras, roughly speaking you have 2 different sizes that are popular (there are others): Full-frame and Cropped sensor. Full frame cameras (like the ones in the video) will let in much more light than cropped sensors. A smartphone sensor is smaller than even the cropped sensor size.

The more light the sensor can capture the faster it can take a photograph, the better the bokeh it produces will be. Mega-pixels are not necessarily related to sensor size but to sensor density. A bigger sensor will still capture significantly more light and so images will come out much sharper in the same amount of time. Also, with cameras you can modify all the parameters required to take a picture (mainly aperture and shutter time) so you have more flexibility to take good pictures. There are two ways of letting more light into the sensor one is to simply open up the lens more (lower the `f` value) and the other is to let the sensor be exposed to light for longer (increase shutter time).

Also 55mm f2.8 means is the lens, lenses have a length, a short focal length (like 11mm for example) will take very wide photos and a large focal length (85mm) will take close ups or "zoomed in" pictures. For wild life photography it's not unusual to see lenses that are like 300mm. The `f` factor is how wide the lens will open and the lower the number the more light it will let in. So for example an 11mm f1.8 will let in much more light in than an 11mm f3.5. The more light the lens lets in the faster you can take a picture and still have it be sharp.

Phone cameras are extremely limited in what they can do with optics, there are many optical tricks you can implement to have different focal lengths on a phone, for example, having 3 lenses: a "zoom" one, a "wide" one and the "regular" one. But ultimately a 11mm f1.8 on a camera will be incredibly better quality than whatever a phone can accomplish in such reduce size.

I hope that explains things a little better :)

Anybody ever build one of these? I made a "sardine can" antenna (https://www.iw5edi.com/ham-radio/1687/sardine-can-antenna) a while back. These type of things look simple, but there are places where the instructions are inadequate or they use some part that isn't available anymore.
More power to you if it's helpful to you.
I don't think it's really possible to seriously consider Haskell as somehow less "dizzyingly complex" than rust unless you're already a math postgrad. I like haskell, don't get me wrong, but it is not in any way simple to write or read or work with by comparison. And while rust has some heady concepts in its design, for the most part even advanced users don't actually need to understand most of them to use it (I think this is actually rust's biggest innovation).

I do wish rust had borrowed syntactically more from haskell than C++, though.
As much as I dislike facebook. Florida is going about this the wrong way. States should simply ban social media, especially for children. It should simply be illegal or highly restricted.

Sounds harsh, but the world would be a better place. Also, government agencies and political candidates should be banned from interacting on social media that is not federated. That is it.

Unfortunately, politicians don't understand the meaning of federated.

This should be done as an anti-trust action, and facebook should be broken up. Twitter should also be broken up, but it is an utterly useless product, so probably just liquidated.

Social media should be for trashy pursuits, not serious discourse. Those should be done on open fora. Hacker news as well ought to be federated.
Adam (cofounder) - great question! Yes, this situation is very common for our use-cases. Ditto supports the concept of `eviction` [1]. For example, imagine a restaurant that wants to store all of today's orders in their devices, but then evict the data when they close out at end of day (and data is synced into Cloud backend). Eviction is a core concept because we consider devices using Ditto's SDK a "Small peer" that should only have the data it wants - queries define which data is synced and you can always evict anything unneeded. Conversely, the server version of Ditto is a "Big Peer" that is a cluster designed for scalability and fault tolerance, so it wants to capture everything. Another way to put it is selfish vs. greedy replication.

To help users with eviction, we are adding support for dynamic queries, for example, using "now" for a date in the query to aid in creating TTL logic. In addition, to built-in TTL as well.

Satellite comms are definitely a great fit for another reason, since Ditto's replication is "delta-based" it will only sync differences. Our protocol is designed to overlay on top of custom arbitrary links, including unreliable ones. Not familiar with CCSDS, but we have explored Link16, and even built-in we replicate over BLE GATT.

Hope that helps and perhaps we can get Ditto into space!

Not quite, but as mass increases relative to Earth, launch vehicles become increasingly ridiculous. Many "super-Earth"s would need something like a Saturn V to get to their equivalent of the ISS, or maybe even their equivalent of Sputnik, depending on exactly how "super".

When you start to get into gas giant mass, chemical launch starts to become really close to impossible instead of just wildly unaffordable.

My Chinese friends tell me when they were kids, all students' grades were made public, so everyone knew exactly how each student was performing. Also, a student's grades were a direct reflection of the family. So, if a student was doing poorly, everyone knew about it, people generally looked down on the parents, like the poor performance was all their fault. I've heard stories about managers at work talking to employees about their child's performance in 3rd grade.

My friends are all in their 50s, and they all tell me they still have nightmares about school back in China. Not sure if school in China is still like that, though.

The difference is that it takes very little lead to make a lead acid battery because the entire car is not powered only by that battery.. that is not the case with EVs. It is estimated that it takes 500,000lbs of ore needs to be mined to get enough material for a single EV car's battery

We haven’t even come up with a material strong enough to build a space elevator here on earth. On a heavy planet you need an even higher strength to weight ratio.

Your space platform would practically have to be a floating city, since mountains won’t even be as high.
People used private forums before? Pretty much every country and even cities have their own subreddit, games all have their own "official" subreddits, and every hobby under the sun also has their own subreddit. I think that's what forums would be replacing. Maybe I'm not old enough but forums were rarely a very private affair, imo.
'Human error' emerges as factor in Optus (AU) hack
The audio format (mono, stereo, 2.1,5.1, etc…) isn’t proprietary. The encoding scheme and codecs are i.e Dolby. However, this is a bit more complicated then what maybe is apparent.

The post production sound department for a film will create and mix the sound to a specific format (usually 5.1) and depending on how it will be distributed, Dolby (or other) is used for encoding the distribution.

Dolby has been popular because it solves for cases when someone only has stereo or when a theatre doesn’t have a specific capability (Atmos) by mixing down or up the film’s delivery format.

It is preferred that audio sources are uncompressed PCM in the WAV format. Most audio in a film is actually mono, but is mixed to a surround format with various effects and processing applied to achieve a desired effect.

When the mixing process is complete, it is then rendered to a delivery format which is usually a lossless format and/or a property format.

It is worth mentioning that the sound mix for cinema distribution is not the same for digital distribution.
Assuming they want to upstream their changes, that kind of runs in conflict with the Linux kernel community's "contribute under your real name" policy. Of course, given the general queering of hacker and open source culture we've seen over the past half-decade or more, it may be that demands for use of "real" (legal/dead) names is now considered outdated and marginalizing.

100% difference in rate is fairly close? I get that these are small rates to begin with, but if your margin of error includes the entire range between 0 and your predication in the first place, does your prediction have any value?
It is what it is. As far as I know, there aren't any viable open source pacemakers. The existence of pacemakers is a wonderful modern marvel, and for-profit companies made it happen. It's likely $100 in materials, but my insurance probably paid at least $30K for the device and two leads. Considering how much engineering went into building it, I think it's a fair price. I once heard that there's roughly a 2:1 ratio between requirements and lines of code.
Yes, I saw. It's kind of an awful feature though.

I think the best approach to a mix of forum and discord-like communities is the app "aether.app" though it had a weird protocol behind it and has been abandoned. But the UI/UX although still perfectible seemed to hit a very nice sweet-spot for me.
False solution? Why because mining isn't being done responsibly in some part of the world?

You could say the same thing about literally anything as no supply chain is perfect. But if there's a problem somewhere, like with mining, you zero in and fix it. The fact that a problem exists doesn't invalidate the entire system.

First principles approach - there's no shortage of materials in the crust, no shortage of energy from the sun, and no problem with cars. Your argument is that they're 'unscalable' well they don't need to be because the population will soon be declining.

> Rust isn't really all that hard. I can write it as fast as I can write Python typically, so that friction you probably feel will go away...entirely.

I hear this a lot. Having written both, it seems to me that the only way to reasonably have this thought is that one never learned to use the repl in Python. This gives me a, say, 2-10x improvement in implementation speed, at least for exploratory-kind of coding.
Sounds like a fun way to go OOM :')
The only FTA 24 hour news channel we have in Australia is government funded, no advertising. Not sure if its existence helps prevent the proliferation of the sorts of channels that seem to exist in the US, though it hardly has any significant viewer numbers.
Fantastic point!

That's almost the same type of response the actual Typhoid Mary had to being told to quarantine and stop preparing food for people. It didn't affect her so it couldn't be real and fuck everyone else. If you think taking any step that has a marginal effect on you in protection of society will count as the "worst non-answer" then you should be afraid of authority figures because you are engaging in the type of society damaging behavior they are charged with mitigating
In demo terms it's an "effect".
Congrats to DeepMind! But why did they give the prize to just two members of the alphafold team rather than everyone on the team?

By contrast, the breakthrough prize in physics was awarded to the entire event horizon telescope collaboration for their image of the supermassive black hole.

I would have assumed that the prize for alphafold would also been awarded to the whole team.
I tried to set up a community with left-leaning people (politics). So we didn't really want the owner - admin - moderator structure that discord offered, instead we wanted a more open way for the community to self manage.

The biggest problem came from the fact that we had been all in a discord server in the past that was deleted by the owner after a political disagreement. So in order for that to not happen again we wanted to have a more "community owned" system so that no one would be able to wield such power without some degree of community acceptance.

Sadly, it was not possible to do such a thing on discord as there ALWAYS has to be an owner to the server that's a single individual. Some of these problems can be solved through bots (you can implement very good voting bots) but you're always fighting against the natural structure of the platform, so no solution is ideal.
Seems to be a popular aesthetic for synthwave compilations on YouTube: https://www.youtube.com/watch?v=ICcFMBzOnYs

I wonder if Drive originated this aesthetic or if it's just coincidence.
Then Emacs is an IDE and Vim is an IDE. VS Code is just a text editor that has extensions for specific programming languages, just like Emacs and Vim. The confusion is just because it happens to be named after an actual IDE Visual Studio, which it has little to do with just for marketing purposes (like how JavaScript has little to do with Java).
Try adjusting for population instead of using raw numbers.
Then account for the fact they test for everybody and anybody for Covid. Not so for the earlier pandemics. Totally different measurements. Imagine if they did the same test protocol back then like they did today. Only then can you compare.

The use and abuse of raw data has been a hallmark of the last 2.5 years. Whatever number makes Covid sound worse is the number that gets published and spread. Anything suggesting it isn’t as bad as predicted is buried as a conspiracy or “not peer reviewed”.
It's possible to start with tests and then generate the code, using tests to ensure it is correct. Humans iterate many times on a piece of code - write, execute, compare with your desired output, AI should work step by step with executions and feedback too.

Unsurprisingly, you're were absolutely correct.

It wouldn't invalidate anything because I can list countless examples of scams, hacks, rugpulls, wallet drainings, fraud, ransomware enablement that the crypto space is responsible for. Any example of the opposite doesn't change the fact that the negative aspects are significantly greater than whatever source you can provide.

The list of course is too large for this comment section so somebody has already done parts of the work. [0]

Any user would be very lucky to get their money back in these situations, but like I said, no refunds or consumer protection in the crypto space when you lose your money.

EDIT: So? My point still stands about accountability, regulations or not, even Paypal knows the buying and selling of crypto assets is completely unregulated after 15 years.

The main point of this thread is that there is more evidence of broken smart contracts causing more damage to consumers and there is nobody to hold scammers accountable when a rugpull happens.

Because nobody is going to get their money back for them.

How is crypto, this brittle, 'decentralised' broken and unregulated system going to augment or replace the current financial system?

Mines will open as demand goes up. No shortage of lithium whatsoever. No technical breakthrough needed. The batteries we have today are good enough. There is plenty of opportunity to mine cleaner and more responsibly, but that's just a policy issue. Not insurmountable.
And then you have the problem of freight trains competing with passenger trains for the same track.
Oh jeez, I quit Twitter and it's followed me here.
I think this problem will resolve itself. Nvidia pulled out all of the stops with the 4090 because they thought (hoped) they were going to be able to sell it in an insatiable market that was begging for the biggest most powerful die possible, mostly because of mining. Gamers have no appetite for such a monstrosity (the gpu equivalent to national lampoon’s family truckster), and there aren’t really any games on the horizon that requires the 4090’s sheer power. Nvidia is probably going to have no choice but to make smaller, cooler dies with more modest gains relative to lovelace in their next generation because thats what the market will force them to do.
I have worked off and on with an overseas engineering company. The department I work through has a secretary who left his South Asian home and family to work there in basic accomodations sending home every overtime hour he could get his hands on. One of the best days I can remember in an office is being introduced to his son the recent engineering graduate who just joined the company. Following the success of that young mans career as he went to better and better jobs makes me smile and shields me a little from the over woke virtue signaling brigade of people who probably mean well but tend to let their outrage at a problem get in the way of actually fixing it.

> Can you imagine all the piles of green chips everywhere if the assembler just kept dumping them until it clogged?

Isn't that effectively the same thing as when the belt stops? You've just added a bit more buffer before everything seizes up, and some extra cleanup.

I'm not even sure you can say factorio has backpressure; the factory getting overloaded doesn't trigger slower production rates in prior parts of the system. The queue gets full and stops accepting input, and the prior machines stop sending input as a result (they could alternatively send input and it be dropped & deleted ala software systems, but that's just making it harder to debug because you don't see the whole thing freeze; the problem/solution is still the same)
I was under the impression that there were no Dolby Vision reference monitors, and that different players, like Sony and Oppo, output Dolby Vision encoded 4K Blu-rays differently, and thus there is no ’correct’ interpretation of the metadata.

This is opposed to HDR which has reference monitors and should look exactly the same on different, calibrated systems.
No. There was an internal nvidia presentation from a few years ago that stated that moving data was the hard part. (I can't find the presentation any more, but if anyone can find it, please post it below.)

Previously graphics cards were essentially designed with a single area of the card handling computation, and another area holding memory. Data would need to be moved from the memory, to the computation area, then back again if there were changes that needed to be stored.

As the computation and the memory demands became larger, those areas had to handle more, but so did the bus between those two areas. What was a negligible overhead for the bus became more pronounced as it had to handle more data.

Eventually the energy overhead of transporting that much data across that distance started constraining what was possible with graphics cards.

That is why graphics card architectures have shifted over time to place memory cache units next to computation units. The less distance the data needs to travel, the smaller the power requirements. It's also led to the investment and adoption of stacked memory dies (why grab data from 5cm away in the x-y plane when we can stack memory and grab data 5mm away in the z-direction).
I think that Taku-App is a good idea and I would like to try it out.

The problem is that there are too many options for people to choose from. You have to go through the whole process of signing up for an account, which can be time-consuming for some people.

My solution would be to make it easier for people to sign up, so they don't have to go through all of that trouble.
I know with the rest of their code base signal has stated that their code being open source is mainly for audit-ability, not collaboration. Maybe that what’s going on here?

Right? Floor space is at an all-time premium with high housing costs. And most people I know have a stack of books/etc. to rise the monitor anyway.
This is factually false, and I'm wondering why you'd say that.

Some of the more common malloc implementations out there are dlmalloc, jemalloc, and tcmalloc. Here is where they call munmap.

https://github.com/jemalloc/jemalloc/blob/c0c9783ec9289e6d1d...

Note that not all allocators work this way, you can see that tcmalloc will instead MADV_DONTNEED. (You can find munmap in tcmalloc, but it's not being used to free memory.)
