> I can set up a netcode.io server and cause it to list any IP addresses I want as "server addresses", then cause a netcode.io client accept that challenge token and permit traffic to that address.

No you can't since netcode.io authenticates packets with a public/private key pair and a sequence id. If either the sequence id has been seen recently or key sig fails it won't accept the connection.

Netcode.io was built by someone who dealt with millions of clients and shipped many high volume games so this isn't anything new.

> If all you want to do is avoid head-of-line blocking on the player's network connection, then multiplexing several TCP connections (even websockets!) will provide the same latency and throughput guarantees that UDP will, getting correct NAT behaviour and resistance to D/DoS for free. Simply drop and reconnect any link on packet loss (trivial to detect on either side), and you only need enough connections to handle the maximum number of dropped packets you can tolerate within the time it takes to reconnect.

> I've seen at least one game on HN use this trick in the last year, so I know it isn't unknown.

Nope, nope and nope.

For one, packet drops tend to happen in bursts so your multiplexed TCP/IP clients just means you're resilient to N+1 drops. Detecting a packet drop is not trivial and you need to go through a whole syn/syn-ack/ack if you recreate. Dropped TCP/IP sockets also don't clean up immediately so you can easily exhaust your available socket resources with this technique.

I played the game that you mentioned and if you seen in the comments the netcode was not ideal. It was pretty obvious that there was some head-of-line blocking even with multiple sockets. Compare that to something like Subspace that ran on a single 250-400ms 56K connection seamlessly back in '99.

Look, I'm sure you're an expert in WebRTC but you don't understand the technical requirements for a realtime netcode. Rather than trying to tell us how we're 'wrong' try listening instead. Games have a pretty unique set of requirements which is exactly why you haven't seen off the shelf solutions like WebRTC gain any traction.
Right. It makes sense to prioritize what you really needs vs. nice to haves. And very few laptops don't have compromises of some sort.

You could look at it this way -- as an experiment, you could buy a cheap Chromebook that runs GalliumOS well (check the wiki first for compatibility). If it doesn't work out, you're only out $300 or so and some time. You could then revert it to ChromeOS and still have a machine for travel or guests that you don't care too much about if it gets broken or stolen. Or you could give it to a a friend or relative who is not very computer savvy and just wants to surf the web.

> How in the world they could jump to conclusions before the people actually doing the investigations certainly beats me. I could see it as being a miscommunication, but this was not a one-off incident.

It is probably just human nature. Many people will continue to think and do what they did before, even after having the error of their ways explained to them. While you might expect a person in a position of responsibility to act more responsibly, it also seems possible that such a person might consider himself to be more competent than average, which would exacerbate the Dunning-Kruger effect - in this case, thinking his hunch about the debris is as good as a conclusion by crash investigators.

A false report of more debris being found might be a misunderstanding of the original find being reported through different channels at different times. An impulsive person, eager to say something, might not consider that possibility before making an announcement.

I think it is rarely that extreme. Preference for stability rarely means complete inability to deal with instable situations. Also, let's not overstate instability of average tech job. It is not that bad.
haha no worries at all!

I started where most people would I think! Alibaba! I sorted and filtered for suppliers that said they could do OEM and I originally contacted about 10 of them - eventually ordered samples from 6 and then when they came in I actually took all the samples apart and examined the boards, the soldering, the wiring etc so I could find which ones were made with higher quality parts and better construction practices.

I had the first shipment sent to my house because I was still afraid after wiring 10k to China I was just going to receive boxes of coal - My next few shipments however are slated to go directly to Amazon because I now feel I can trust my suppliers.

I'm happy to go into more detail if this is helpful?

I worked in a company with a lot of 18-25 year olds recently.Based in Barcelona but a very international mix of people. They seemed to do a lot of drinking and a lot of social media (we had a work trip to Rome one weekend and they looked nervous when they didn't have wifi or their phone was out of charge).

As it was a very international crowd out of their home countries and most working in sales maybe it captured a fairly extroverted sample of the age group.

I'm not the OP, but here's what I did at NASA that I found interesting:

- Developed the space lidar that will measure the polar ice cap melting

- Created a dashboard to monitor a spacecraft in deep space (and then ran ops for it)

- Developed learning models on a top500 supercomputer

- Optimization of 1000-GPU (yes) detailed simulation of the earth's magnetosphere

Yes, I knew that the industry will pay more, but honestly, I was young and just wanted to have a good time and stay around family in the area. The other jobs in the area didn't seem as exciting.

> Rainbow Grocery was sold out of its Fountain of Truth spring water

Although it's currently the zeitgeist to mock "Silicon Valley elites" at every opportunity, Rainbow Grocery in SF is cut from the same cloth as Berkeley Bowl in the East Bay, i.e. serving the wealthy hippies that have lived in Berkeley (and to a lesser extent the rest of the Bay) for many decades. Some of those made their money from tech in SV, many did not.

While I'm sure the author had a fit of ecstasy when they found that the Jucero CEO was a fan of this product, this really has little to do with "Silicon Valley elites"; this is the same extreme hippie contingent that oppose vaccination (the hint is in the product name: "Fountain of Truth" is clearly marketed at spritualists not technologists).

> While I can understand the stance of the catholic church I still think that logically you cannot oppose abortion, while supporting the death penalty

I think that the Catholic view is that murder is defined as "intentional taking of innocent human life" and that it is immoral. In this case you are not intentionally taking an innocent life. Similarly in case of abortion, the church does not oppose treatments that could save the mother's life that could cause the child's death. Here, your intention is to save the mother's life, not to hurt the child. The loss of child's life is an unintenional but unavoidable side effect : https://en.m.wikipedia.org/wiki/Abortion_and_the_Catholic_Ch...

Had the same experience with my son's ear infection on a holiday weekend. Received a bill for $900. I refused to pay it, I wrote them and said I had asked to receive an itemized list of charges for a typical ear infection and had been refused and that if these prices were known at the time of the service I wouldn't've undertaken the service.

So of course they came down to $450 without even batting an eye. Complete madness. I've still never paid it, with no apparent consequences.

> a very strange and questionable interpretation

Two lawyers I've talked to about agree with my interpretation. Dan Geer has also been warning[1] about the consequences of the Kyllo decision.

> that doesn't mean the general public uses Alexa to listen to people

The Kyllo decision doesn't dep[end on the use, only if the public is generally familiar with the technology. I linked to the court's opinion in my previous [1]; the complete opinion is at the end of section (b) on the first page:

>> obtaining by sense-enhancing technology any information regarding the home's interior that could not otherwise have been obtained without physical "intrusion into a constitutionally protected area," Silverman v. United States, 365 U. S. 505, 512, constitutes a search--at least where (as here) the technology in question is not in general public use.

The court did not specify how the general public was using the technology or the purpose for using it. Justice Stevens dissent specifically addresses this problem

> Despite the Court's attempt to draw a line that is "not only firm but also bright," ante, at 12, the contours of its new rule are uncertain because its protection apparently dissipates as soon as the relevant technology is "in general public use," ante, at 6-7. [...] it seems likely that the threat to privacy will grow, rather than recede, as the use of intrusive equipment becomes more readily available.

> the general public does emit unshielded heat signatures

This is irrelevant. Of course they do. However, the court observed that the general public \ was not using thermal imaging cameras to receive those emissions, and thus the had an expectation of privacy about their heat signatures. Note that this expectation co9ud change if most cellphones start including the newer "multispectral imaging" devices.

> but doesn't observe those signatures

People using an Alexa do expect that some of their speech will be recorded and transmitted to a large business over the internet.

Agreed. Just turned 22 this past October. I had a very similar experience in that I couldn't go somewhere unless my mother had met their parents (which rarely happened) and like yourself I was hooked to my tech. It has payed dividends career wise but I didn't get to be too social growing up.
Sorry this is just such a bad, bad, bad example. It completely ignores so many facts:

1) Your example ignores accidents that happen: people get sick even when they've got healthy lifestyles, people are hurt in accidents, etc. Sometimes you have a baby prematurely born that has to stay in the NICU for months, already running up a $1 mil bill before they've even come home. Childhood cancers.

2) A lot of what gets people unhealthy is also things that they aren't aware of. We've only in the past 5-10 years had more awareness of just how much sugar is in EVERYTHING. Same goes for chemicals, pesticides. These are all choices that consumers haven't actively made, but were made for them by money'd interests.

3) Would you say the same about your parents? About your loved ones? About your children that ate too much candy, or drove too fast in their teenage years? Probably not.

My opinion is that American society (of which I'm a part of) has gone too far in the direction of individuality and "I've got mine, screw you" – and we're all suffering for it. We no longer think as a collective, but instead just look at everything through the lens of ourselves. Healthy people included. You just don't know it yet.

I have a lot of respect for moxie helping create the signal protocol. I think the problem is many extend that respect to take his word as gospel for everything else, including stuff like this that is total nonsense.

1) We -can't- just take the backend of signal and deploy our own because all clients are hardcoded to use Signal central servers. You currently -must- trust central Signal servers to not store metadata and the government their servers live under. You totally can have end to end encryption -and- have federation as Matrix.org and Riot.im have well demonstrated.

2) There is no reason at all you need to be centralized to encrypt SMS via the signal protocol. The Silence project has already demonstrated this https://silence.im/
You can design a bus for these tunnels fairly easily. However, 140mph under a city vs 3 mph at street level and buses lose unless they have 47+ passengers but a 50 passenger bus costs 2-3 car slots easily so it's a wash.

PS: I-66 really does have 3mph traffic as it will take 30+ minutes to travel 10 miles. As in I was happy if that part was under 30 minutes, and not surprised if it took 40 minutes as the average was well over 30.

I disagree. It's not a straw man at all.

Your assume that
A) big things can only ever get done by companies.
B)A CEO 'owns' a company's assets.

I'll give credit to him for creating and acquiring funding for the organization. I'll give him credit for publicizing his vision. Each and every rocket/car however, was massively subsidized by taxpayer dollars, and made feasible by hundreds of people WORKING TOWARD A COMMON GOAL.

The practice of abstracting away hundreds to thousands of people's hard work and financial support, involuntary or not, is disingenuous at best and downright dishonest at worst.

Abstraction is evil. Abstraction is what turns "people" into "human resources".

And before the inevitable "That's not practical!" or "That's unreasonable!": It really isn't. Most people have just gotten so used to credit for their own work being sacrificed to someone else that nobody points out how incredibly screwed up the practice is.
No, but the underlying hardware that perviously hosted two m5.xlarge instances may instead host one M5.xlarge and one M5.medium, so that performance is not degraded.
That's right. Sometimes part of the fun is having an understanding of what the theory is useful for, and how it could impact science overall in the medium and long term, even if we don't get anything at all about the workings of the theory itself.

Elon Musk always plays pretty close to the line. If Tesla wasn't so leveraged, doubtless Musk would immediately start trying to expand to more and more Gigafactories until it was.

The situation for SpaceX is different. SpaceX got 18 successful launches last year, several of them with reused rockets and most of them recovered afterward (no unsuccessful landing attempts, though a few were intentionally expended for performance reasons).

Their only real domestic competitor ULA which launches Atlas and Delta, long held as the giants in American space launch, only had a total of 8 launches, all expended of course.

Not only does SpaceX have a huge technological moat in the form of operational space launch reuse, but operationally their Falcon 9 (which had complete success in 2017) is out-launching everything else, including both the Chinese DF-5 (which had a failure) and the Russian R7/Soyuz (which also had a failure).

And their future products build tremendously on this already sizable lead:

1) Falcon Heavy, completed pad fit checks by the end of the year and now getting ready for a static fire and launch in a couple weeks, is even MORE reusable (3 cores recovered, counting for 27 out of 28 of the engines) and MORE powerful than any other rocket launching today. Dragon Crew also nearing completion and will be the first (of 3 total vehicles nearing completion) to return Americans to orbit on a domestic vehicle, likely this year.

2) A satellite constellation which is readying satellite prototype launch in the next month or two, has the potential of making SpaceX a telecomm giant. The scale of this constellation would not be feasible without the reusability tech they've developed.

3) And BFR, which will further cement their space launch tech moat, make launching the full version of the potentially-extremely-profitable satellite constellation WAY cheaper, and potentially open several new markets.

SpaceX is like Tesla after a full ramp-up of the Model 3 selling as many cars as Toyota does but in a world where no one else has an electric car for sale. So understandably (for Musk), he's leveraging this position to make things like BFR a reality.

Both companies are in extremely good positions compared to 2008 when both companies nearly went under. SpaceX in particular. And given the fact that Elon was able to save both, it means a market down-turn is something he has seen before and he has some powerful strings to pull in case the market has some major problems.
If your parents had eliminated screens when you were very young (including theirs) save maybe one publicly-placed crappy terminal for wikipedia or looking up business hours or maps or learning you some programming or whatever, but loosened the reigns on hang-outs and travel, do you think you'd have still felt isolated because all your friends were still online most of the time?
