> other comments that question the ratio of benefit vs. risk

I think it is important to note that different people will have different inputs into benefits and risk. E.g. a 24 year old male living alone probably doesn't have a use case for elderly fall detection, etc. But, a 75 year old woman living alone probably does.

Also, I am of the opinion that is possible to do this properly (i.e. securely and privacy preserving). Case in point: people carry microphones (in phones) that can record any audio with them... but they do it because they trust that their phone is secure and private.
It doesn't seem at all line they're claiming that lab escapes never happen. Just that this particular lab is known for being extremely safe, and that it's therefore unlikely it would have had a leak.

For a leak of such a virus to happen from a BSL4 facility that routinely handles much more contagious viruses, you would need incompetence or funding issues, yes.
This seems like the misuse of impressive sounding words. The hypothesis has nothing to do with US law. It’s a question of whether there is sufficient empirical evidence in support of the prevailing hypothesis, that the virus originated from a market in Wuhan.
Okay. China created it. Now what? I have yet to see anyone explain what they would do with the result that is somehow beneficial.

Does knowing this help fight it? Does it help stop it? Does it help treat it? Does it help stop the spread?

Let's say China even INTENTIONALLY did it. Then what? You gonna invade China? Exactly how are you gonna make someone like Apple pull out of China when they should already be doing that NOW for other reasons?

I regard the "lab leak hypothesis" like I regard news about celebrities--worthless and unactionable.

It's simply a "boogeyman" to focus hate to create the "in group" and the "out group" for propaganda purposes.

> lights turning on automatically when you enter a room

Was this really it? Or did they have some use-case not currently covered by motion sensors?

I can see some potential use for security (cheap REX sensors can be easily tricked, allowing unauthorized access into secure areas). The fix is obvious (stop cheaping out on your REX sensors) but I can envision someone trying to bill wifi sensing as the hip new solution for REX systems.
> I can link a raspberry pi anywhere in the world to my XMPP server with a few lines of Python and some libraries.

Once again, "I, as a tech-savvy person, can operate my highly-customized XMPP setup everywhere", while ignoring that most people do not run their own servers.

> they discourage people from using other clients

This was discussed numerous times various platforms and proven wrong.

> I can verify that my server isn't tracking users

As discussed before on this page, most XMPP users don't run their own XMPP server but use a public XMPP server on the internet. Nobody can check whether this public XMPP server tracks its users without accessing the server itself.

> all of your eggs in a centralized basket, both in terms of privacy and reliability.

So, do you assume the Signal network infrastructure consists of a single server?

> Do not know of a single XMPP client that requires a phone number

At least Quicksy (from the Conversations developer who bragged in a public video about copying WhatsApp/Signal) and Kontalk require a phone number. They even market the phone number requirement as a benefit in comparison with other XMPP clients.

> most people will tell you

I could just claim the opposite. Without any sources, it remains an assumption.

> Signal doesn't

Signal does. You wrote, you use Signal. Did you ever join a Signal group? There is a dialog when entering a group the first time.

Those costs are amazing. I just compared two state universities I'm familiar with, and the fees are vastly different - but the schools are ranked similarly. These are relatively low ranked. Heck, I just compared to a different top 10 state school, and it is cheaper than one of the no-rank schools.

I guess it all comes down to which state you live in.

If China screwed up and didn’t follow proper first world standards for their research and directly caused 2 years of hell for the rest of the world then they deserved everything that would have come their way. To hell with the future of science in China, some fuck ups are too big to sweep under the rug. Sometimes you need destructive anger. Sometimes you need raw political backlash.

It’s really bizarre to me that western scientists would feel more obligated to defend the future of scientific progress in a foreign communist country (especially one that’s currently engaging in an ethnic cleansing not seen since WWII) over their obligation to their own country and more importantly, than their obligation to the truth. These people have taken scientific and technological progress as their god and it’s impossible to understand their actions if you haven’t.

Software "Engineering" is not really an Engineering discipline, such as Civil Engineering, where there are norms, standards, accepted practices, regulations, and a body of knowledge that hasn't changed much in hundreds of years. Or compare it to Mechanical Engineering, which is similar.

In comparison, Software is a very young field, and is not regulated at all. Open any EULA and you will see that you are indemnifying the vendor from any sort of liability to the maximum extent possible. Further, software is only loosely limited by physics: almost anything that you can imagine can be built using software, so software creations are incredibly complex, and are all man-made, with extensive combinatorial inputs that simply can't be tested or are not feasible to test economically. Also consider that fact that software is almost always purpose-built and not comparable to a mass-produced artifact such as an IC engine, or a girder, or a length of rebar, or a chemical reagent. So the methods of Industrial Engineering, which concern themselves with quality control in the face of uncertainty do not neatly apply to the software world. The rate of change of software artifacts is just mind-boggling: once a bolt is produced, that's it. It doesn't need to be continuously maintained, updated, or improved, because it simply doesn't possess the malleability of code. If you fasten it with the right amount of torque, you are probably good for an indefinite length of time and can expect to simply forget about it. The software equivalents of nuts and bolts, such as compilers, are nowhere near as simple as nuts and bolts: they are whole universes in their own right, and every detail of that universe is man-made, conceptualized from scratch.

I could go on, but given that software is so complex, it is to be expected that it doesn't hold up to your notions of quality.

If you want to look at large codebases that have maintained a high quality, the obvious recommendation is the Linux Kernel. Another is the Go Standard Library, which is very readable and well-written. I think musl, a minimal libc replacement, is also considered very well-written (but perhaps it's not a huge codebase). Postgres source is also widely known to be pretty good for such a complex codebase that is worked on by a large group.
It's not a science page on Reddit, the source is a published virologist who himself cites dozens and dozens of sources.

I find it odd that people are commenting about how this doesn't inspire confidence, but "rootclaim" as well as an editorialised headline from the telegraph is.
The difference is the light gathering size.

The larger the aperture, the smaller the resolved object that we can look at. For example, looking at the central black hole of M87 which is on the order of "diameter of the solar system" ( https://xkcd.com/2135/ ).

However, the only reason we are able to resolve it is that it is so bright.

But if you want to look at dim objects, then the area of the light gathering is the important value. That is why Arecibo was so important ( https://ui.adsabs.harvard.edu/abs/2005AAS...207.2907D/abstra... )

For the HSA - it used the largest of the radio dishes available - https://science.nrao.edu/facilities/vlba/HSA

The Green Bank Telescope 100m and the Effelsberg 100m telescopes are much more sensitive than the VLA... but the VLA can resolve 0.2 and 0.04 overall.

So yes, we could send up a bunch of 3m space telescopes out to the L2 point - but how many individual miniature instruments are we going to need to make for each, how much propellant will be needed for each, how will you keep the cold side cold (size matters)?

While I'm not a rocket scientist, I'm not sure that those are easy problems to solve... and I feel like they're much harder problems to solve than ones that the JWST and the current line of telescope proposals have.
If not even Microsoft is willing to make that investment (given its vast resources), it's unlikely any smaller players would. I agree with the sentiment (diversity is good), but it's extremely expensive to build a browser. Maybe that's the real issue.
The civil war ended in 1949. So this was an attempt of invasion after the end. What happened after 1949 in both Taiwan and China was horrible. But thankfully Taiwan is thriving now. If only could get over it’s illegitimate claim to Taiwan so my family and I can feel safe.
This is extremely impressive. It’s the first GAN I have seen which lets you tweak the result in a meaningful way rather than being just random.

I think the speed that GANs have come in to the world has really shaken people up and it’s hard to process what this all means and what it will result in. Especially the ones which generate based on real people.

But the feeling this gives me, is what happens for the future of art. Sure, this example is no where even close to replacing real artists, but it’s already generating images better than I can draw after a year of practice. It does give me a feeling of “what is the point”. Which might be an irrational feeling, but I’m sure others feel the same.
Yes, Quicksy from the Conversations developer who bragged about copying main features of WhatsApp and Signal.

Another one is Kontalk, https://www.kontalk.org/.

Both XMPP clients require a phone number, and both present the phone number as a benefit in comparison with other XMPP clients without this requirement.
It’s funny that you mention that. When I was reading the article, it occurred to me how biphasic (or multiphasic) sleep resembles the schedule of a newborn’s parents. To me the lack of artificial lighting is a more compelling explanation, but who knows there could be many factors that contributed to the habit.
I seem to notice this particularly often with a subset of developers. People who have a very strong "who moved my cheese" mindset. They are used to doing things a certain way. An approach that is simple to understand, but takes a very long time to get anything done. Ie, writing vanilla HTML without any frameworks. Besides, they aren't the ones paying for a team of developers, so they don't really see a downside in spending 1 month to do something that could have been done in a week.

And then all of a sudden, everything starts changing. Nobody wants to hire a vanilla JS/HTML developer anymore, they want react developers. And these react kiddies are able to put together a webapp that looks so much nicer, has more functionality, and they are able to do it in less time.

They decide to try learning react, but find themselves with a tough problem they haven't dealt with in a while - being outside their comfort zone. They are so used to doing things a certain way. They know exactly how to do it. They can do it blindfolded. And all of a sudden, they find themselves having to change everything up. Overnight, they go from feeling like experts to feeling like novices. And they hate it.

If they pushed through it, they would eventually gain mastery over it and learn to evaluate this new technology fairly on its merits. But they never do master this new technology. Feeling like a newbie is too psychologically painful. But they also recognize how much of a disadvantage they are at by not riding this wave that is taking over the industry. And so, rather than expressing indifference or acknowledging personal taste, they lash out with tremendous resentment and anger.

I get it. Change is scary. But it gets even scarier when you try to resist it instead of embracing it.
Why does every solar geoengineering project seem to pretend that decreasing solar radiation wouldn't impact photosynthesis which also binds CO2, and, uh, supports the entire food web / our civilization?

We already are massively stressing the biosphere: mass extinctions, mass destruction of habitat, mass disruption of migration patterns, warming, plastic pollution, invasive species.

And the suggestion is to reduce incoming photosynthetic energy by percentage points????????

I get that photosynthesis happens in a narrow band of frequencies compared to other solar radiation that would be absorbed then emitted back/trapped as IR radiation... but still, geoengineering should focus on methods that explicitly track the bound/removed CO2.

Note I do not for a second believe that schemes for sequestration by pumping CO2 deep underground won't have huge amounts of ignored/undetected leakage, especially since it is a petroleum industry scheme that already pretends massive methane leaks aren't occurring far more than is accounted for in current petrol extraction.

Kind of. The Posse Comitatus Act doesn't apply to the Navy. However, the DoD and/or the DoN has regulations that align with the Posse Comitatus Act. So it's not the military as a whole which is forbidden, just part of it, and the other part can change their own rules to allow it.

Intense preemphasis and equalization are table stakes for high speed serial these days. Have been since PCIe3. By Gen5, the fundamental lobe goes to 32GHz, and the mandates are steep. It has to be able to fish the signal up after the dielectrics have eaten all but a few parts per thousand of the high frequency energy! Compared to modern transceivers -- these new ones or even, if you'll indulge my speculation, the transceivers in your own computer that are going unused by the dozen -- compared to those, dual simplex 10Gb/s just looks... old. The price doesn't really match up, and I wonder if it's a business thing or if there is an unfortunate design choice that baked in some manufacturing difficulty.
I can’t understand why the GP comment is flagged. If you can look past all the “culture war” stuff, this is pointing out some of the limits of algorithmic creativity.

It does not do well generating instances with features that are not well represented in the training dataset.

Compare this to human creativity. I suspect that fulfilling GPs request would be almost trivial for a human professional artist.

To be clear this is an amazing achievement, a creative use of the technology, and a positive contribution to the world. Pointing out limitations (i.e. areas with potential for future innovation) does not diminish it.
> As an industry, we should be deeply ashamed at how much of the world's time and resources are wasted running poor software so a company can save a few bucks.

This seems like you are saying everyone should write in assembly or c language for ever task possible, since that's the only way to avoid "wasting the worlds resources running poor software". At some point the trade offs are not solely "so that a company can save a few bucks", the trade offs also are things like "why spend 1 year writing a simple server which I can write a far superior server in say python/go/etc. in a few minutes". Yes, I understand you may be more specifically talking about Electron here, but at what point are you allowed to stop focusing on saving a few KB of ram or CPU cycles and focus on actually getting things done? Feeling productive? More platforms?
Patterns of Distributed Systems – Replicated Log
As a veteran of IF and many other diet experiments, I think the primary value of IF is mental training to tolerate hunger. Secondarily, it’s a structured way to make drastic calorie cuts more mentally tolerable. Thirdly, it opens up a lot of time and attention for other things. I built an elite fitness level on IF, but I was getting very light-headed in training, so I stopped and then I could never train because I was always full or hungry. The best solution seemed to be what so many elites settle on, which is taking nutrition only during training sessions, and then one big meal before bed. It was hard to focus on work though, and I had to admit to myself that they don’t have that problem, but I do.

So, in conclusion: yes, do it. Use the ‘one meal a day’ version. Exercise at the end of the fast, which is going to suck at first, but tell yourself that it is mental training, and admit to yourself that this is what you actually need more than the physical diet right now.
