Vehicle Driving Simulators
This consists of three major parts:
1) The game engine that simulates the physics of different driving scenarios and rendering them to the drivers display.
2) A six DOF motion platform that is used to recreate the motion of the vehicle.
3) The vehicle body mounted on-top of the motion platform that has the steering wheel and other controls exactly like a real vehicle.

The driver inputs are read and fed into the game engine which outputs the rendered video to the vehicle LCD's. The output from the game engine is also used to control the 6-DOF motion platform to recreate the physical motion one experiences while driving.
Norway seems to have timed the contagion enough to be able to handle it and mitigate, but you never know until too late as curve remains exponential. On the other hand, we get critizised for not having enough deaths and infected. The counter argument is that mitigation and herd immunity could take years, though other examples show we'll soon be able to open up kindergartens, schools, unaffected communities etc. and not remain in "lightweight" lockdown.

This may not be over for years, though we will grow to be able to handle it. There's yet not enough evidence which strategy is "best", however avoiding full-blown crisis and delaying unknown unknowns seems prudent.

Apple waives 30% cut from video subscription apps
I keep hearing from friends in Germany that the death numbers reported are completely bollocks. They say the people who die with pre-existing conditions aggravated with the coronavirus are not counted, nor the people who are not tested after deceasing. Whereas in Italy seems everything that dies in the medical system these days is being counted.

Would love to see someone confirming or disproving this...
> easy to destabilize public confidence in voting outcomes

The last few years of politics in the US has highlighted for me how brittle electoral democracy really is, and how important the public's presumption of fair elections is to the system functioning.

Those of us who work in the software industry and know how the sausage is made should consider using our voices and experience to share with family and friends just how buggy software is in the real world, and how inevitable problems are, both due to malice and simple mistakes.

Yes, you can have e2e encryption videoconferencing with large groups of people - just not using webrtc (unless you do some crazy hacks - mentioned in my other comment).

By definition, a transcoding server or supernode (acting as an MCU - Multipoint Conferencing Unit) would be a MITM, so that wouldnt be e2e encrypted.

A simple way with WebRTC for a small conference, would be to transcode on the origin and provide multiple streams to peers - one for thumbnails, one for higher quality, low bandwidth fallbacks, etc. This doesnt scale well, but it works nicely for small conferences.
People who care and have the time to spare might, but this is standard PR crisis mitigation technique and the goal is to have a large mass of the users thinking "ah, this was just a mistake made under pressure in crazy times, zoom is ok now, still convenient".

I could only image being blind and having to navigate a world that is completely flat. Knobs and controls add something to grab onto. to me it's also safer, if I'm driving and want to change the radio channel, i can feel for the knob without having to take my eyes off the road. i can't do this with a flat, touchscreen display and I also find that voice command work most times but, on the time they don't, i get frustrated and that's not good when driving either as it can cause road rage.

How to Block Facebook Web Trackers at the Firewall
While this is amazing site for reference, it usually doesn't replace buying sheet music that you intent to perform. Sheet music is generally printed in various large formats (which is nicer for reading music, but means you need a large format printer). Scaled down to common sizes will make the music to small.

So if anyone is looking for a product to produce: A large format B&W laser printer that is consumer priced - basically a musicians printer. There are consumer priced large format printers, but they all seem to be inkjet.
I upvoted you in a (futile?) attempt to restore some balance.
<rant>

The people behind Zoom have no obligations to you (not you, OP, the general 'you') at all.

They built the product with the Facebook SDK wired up to report your activity back to Zuckerberg. They told you about it in the T&Cs which you agreed to. They built the product, as they rightly point out, for a different, constrained market where Zoom gatecrashing wasn't considered - not the whole world in a pandemic crisis, where people will always try to exploit platforms for exposure and profit.

If you don't like Zoom or what they are doing, don't use it. They owe you nothing. Acting like Zoom have some kind of social responsibility to you because it's suddenly the most convenient tool when you're stuck at home is ridiculous.
Governments could only get the data down to the range of individual mobile cells, which is way too large to use for any useful contact tracing.

That's why BLE works, it's because it's a very low distance technology only phones actually within a distance that are relevant are going to show up.
When you can put more transistors, you have to use them for something. You can either put more cores, but that requires for software to be written in a way to utilize those cores and that's not always easy task or even possible. Or you can use those transistors to make some common operations faster and that potentially will increase performance with little rewrites (or even with no rewrites for libraries).

"This is enough" will be said when we wouldn't be able to put more transistors. I think that it won't happen in the next 10 years, but, of course, it'll happen eventually.

Beautiful stuff. Brian, thanks for writing that up - I don't think I have used Screamer in 20 years, but I will put playing with it on my TODO list.

I have been using Common Lisp for about 38 years for research and building commercial products, and it is amazing how portable code is through the decades.
Agreed. I think a way through this may be to emphasize the notion of 'performance rights' over 'copyrights'. So distributing a work digitally, for consumption on a personal device, would be free of encumbrances. But performing the work, which would include physical embodiment, e.g. turning into an actual book, or entertaining an audience, would be something that could be controlled and monetized by the author.

I am an orchestra musician moving from live concerts to streaming in these Corona times. Imslp is a great resource, since many publishers are low on staff, or have stopped renting out music entirely since last week.

not only that, the music can be live-streamed witout paying royalties. it is great for us as a way to figure things out with streaming.

In some cases especially hardware, it is essential that PID tuning is done safely.

I remember reading somewhere that nowadays a significant chunk of the instructions isn't actually implemented on the CPU using transistors, but by using CPU microcode to sort of emulate these instructions by combining existing ones. Someone correct me if I'm wrong.

A lot will have to happen _during_ lockdown, you can't just sit idly by. Basically it will buy time.

Of course the virus will still spread once lockdown is lifted, but for countries like the US (not even to mention Italy and Spain) who started behind the curve any time you can buy to bolster your response should be taken.

The intent of "Wi-Fi 6" is to start versioning Wi-Fi numerically (i.e. the next major rev will be Wi-Fi 7) instead of the IEEE's ever-lengthening 802.11 alphabet soup.

It's just a coincidence that we're also talking about 6 GHz at the same time. No formal relation.
It is encrypted, yes. The discussion is over end-to-end encryption - i.e. is there a middle server that has access to the unencrypted streams, or do peers communicate directly with each other. This depends on your implementation.
I wonder what effect your proposal would have on open source software.
Also, there's a thing called "calendar". One can send invitation for a specific time (via another cutting edge tech, "email"), and include an URL to the meeting.

There are two aspects to this, first you hired the wrong person and, second, the financial situation gets bad enough that head-count needs to be cut.

Regarding the first problem, 6 months should be enough to decide whether the new hire fits or not.

The second problem is a little bit tougher. There are two solutions, so. The first one is fixed-term contract, 1 year, 2 years. These can be extended (twice, if I remember well), which can be good solution for start-ups where long-term revenue is hard to gauge. The second is simple lay-offs. For young companies not that much a problem if there is a clear economic reason. You just close a department.

If cutting long-term employees is a problem, maybe the underlying root cause is bad head-count planning, read over hiring above needs and the companies cash-flow. Employers complaining about "firing is so hard in Germany" is a little bit lazy if you ask me. Don't over hire to beginn with, also helps in situation like Corona as the cash position is much better.
I think you have a couple of things mixed up. A stun server is different from a signaling server. Jitsi is an SFU, which is neither. The behavior you describe with combining streams is what we call an MCU. An SFU is simpler and just forwards streams. Most of the logic of an SFU is in controlling RTCP protocols, which are typically aimed at one-to-one use cases. An SFU has to make this work for a one-to-many use case.

> 1) Transmission via surfaces is thought to be important (afaik).

According to Hendrik Streeck, a leading researcher in Germany, this may not be the case: https://youtu.be/VP7La2bkOMo?t=231

They are working on a more formal study of this but indications are that the viruses that other teams have found on surfaces may be "dead" (in the sense that they cannot actually replicate anymore and therefore are not bioactive relatively soon after leaving host organisms).

Video only in German, sorry, sure this will get publicized internationally if the study confirms the indications.
I use it in Firefox all the time with no difficulties. The only thing that doesn't work for me is selecting an external (USB PnP) microphone, but apparently that's due to a longstanding bug in Firefox that Jitsi is doing its best to work around.
The infections in Germany were the same as Italy after the same period.

Italy is getting better now but it was already a hard hit when being at the same level as Germany is now.

If the numbers are right, things are already at its worst in Germany while still being much better than Italy at its worst.

This. The leader is the target and his/her actions will be scrutinized and critisized.

Yet if you build upon your team and create mutual trust, people will follow you and work really hard. That's the rewarding part of the job.

Regarding higher-ups, you have to choose wisely, most of the time it's very difficult because you give them what they want, but it costs a lot of time, energy and money.

Be pedagogic, explain, and explain. The most difficult part is when you want to take action that doesn't give reward instantly (CI/refactoring/...). Until they've been bitten by this, they won't understand. But you won't know beforehand, so ask the question in interviews !

Promote your best teammates eagerly and give them responsibilities.

Share as much information as possible with the team.

Enforce collective decision processes based on technical merit and cost (RFC-style), to rally everyone to the chosen solution.
I see! I didn't mean tiered caching. I meant, if a thousand clients simultaneously request a cacheable resource from the same colo that lacks the resource, only one request should make it to your origin, and the response should be streamed to every client. This is possible in Fastly but IIRC it depends on what combination of http and https your client and origin connections are using.

Thanks for making OBS!!

Yesterday they still wanted to publish the source code and architecture as open-source, seems they're already back-pedalling on that though and only want to give access to partners. Personally I think a full open-source approach would be better.
I read this the other way around.

The death numbers from Italy were completly insane, because they counted in people who would have died anyway and just happened to be infected by the virus at the time of death.

Don't know which is true.
Shift – A Quarantine Movie
They have _actively_ engineered solutions that are bad for the users with no justification. It was extra effort, which means less speed and more complexity in order to get them in place.

This has nothing to do with delivering fast.
The clients could control which video streams they want to subscribe to without the server decrypting them.

If you want to support thumbnail/fullscreen versions of streams, the clients could just send along two streams or use a codec that supports this kind, like h.264 SVC.
This is way cool, yet violent!

Substantial to whom ? Often people who downvote will prvoide additional information as to their reasoning which can be substantial or insubstantial like any other comment.
"We didn't design for for scaling overnight" is different from "we did care for security until we got caught"

However small or big, a company shouldn't be selling data without user consent, shouldn't use terms end-to-end encryption while make otherwise claims.

You are correct. I didn't know that, and now I found the actual statement from the NY DOE

As for serology tests, I may be jumping the gun, but only a bit. My employer started paying for coronavirus home test kits in the UK, with the aim of having people come back to work if they show the antibodies. They don't have anything similar in the US simply because there's no FDA approved similar kit. But this will probably change soon.
Isn't that just for text? I know Signal uses WebRTC for Audio & Video and doesn't yet support group chats, (unless something changed recently)?
There is no actual urgent need for software engineer to be more "leaderish". It is totally okay just to do your individual contribution, build expertise, give good task estimations, solve problems, things like this.

I beleive it is a better idea to get strait feedback from your manager about actual cause of your discharge. Maybe you are just plain wrong about it.
"Until we can secure digital voting systems, we shouldn't use them."

Someone, please remind me again, why do we need digital voting systems? For the convenience of getting the results a couple of hours earlier? To save the climate? To eliminate recounts? Because using paper ballots feels too archaic for our high-tech modern society?

People tend to speak about electronic voting as a settled matter. I must have missed the debate.

Not sure if this answers your specific questions - but I found an article written by a dev from Jitsi, describing the architecture of Jitsi Meet:

Improving Scale and Media Quality with Cascading SFUs

https://webrtchacks.com/sfu-cascading/ (November 2018)

Edit: Based on another Jitsi dev's comment in this thread: SFU stands for "Selective Forwarding Unit", which was extracted to a standalone project, Jisti Videobridge.
I don't think you've read my comment correctly (maybe I wasn't clear sorry).

I never said the app is useless, I said that "claiming to respect privacy" on a website is not useful if you don't prove it with open code.
Yes, I don't really know what's true.

I can just have assumptions on what is reported.

To me it seems that the US is spiraling out of control, Italy and Spain had shitty health systems so they didn't do well and Germany doing okay.

But yeah, could be totally wrong reporting.
Mine do, and it doesn't help. I only have 1 desk in my apartment where 2 27" monitors can be placed and it's my personal desk. So now I'm working from my wife's desk that she doesn't use right now (and I can restore it easily), it has space for 1 monitor + laptop. It's not perfect, but I'm not complaining. And I am indeed lucky to even have 2 desks in 70m2 apartment and a dedicated office. (No kids).
