>Would the heat expelled be bright enough to be picked up in this type of imagery?

I would assume so. It probably takes a lot of energy to rip open a hole in spacetime, much less keep it open, and the only things we know of that can do anything like that are black holes. But unlike black holes, a wormhole wouldn't have an event horizon (otherwise you wouldn't be able to go in and come back out) so all of that energy can't be captured, it has to radiate somehow (as it does even with black holes as Hawking radiation.)

Also, the endpoints may have their own accretion disks or there may be red or blue-shift effects that may be detectable, due to the relativistic effects of the endpoints and dark energy expansion.

Basically, this seems like a "stealth in space" problem, and the consensus is that there "ain't no stealth in space[0,1]."

Space is very, very empty and very, very uniform in temperature, as well as being an insulator because it's a vacuum... anything warmer than cold space itself is going to be hot enough to be noticed. The second site linked there mentions that it would be possible to detect a Space Shuttle using its thrusters from across the solar system with current technology. A wormhole big enough to see an entire star through should definitely be giving off something.

>Can energy be expelled in ways not visible to these types of devices possibly?

Not without using more energy and generating more heat. You can't escape the laws of thermodynamics.

>I’m curious if they should try imaging the stars in another sort of way than the past and present catalogues have done in order to possibly capture this any sort of anomalies that we may not currently be aware of.

I'm sure they've put a lot more effort into considering reasonable alternatives than you or I have. But AFAIK, many models of wormholes exist in various physics models, and require exotic matter with negative mass (also only known to exist in theory) to allow any sort of traversal at all, so it's not surprising that astronomers haven't tried ruling them out since at the moment we don't even know if they exist or, if they do, what properties they have.

Can you give an example for one such lie coming from Ram Dass? I'm not saying there isn't one because I'm not familiar with his work but I'm familiar with another "flawed" guru, Alan Watts. And while you may not enjoy his ideas or think he is correct it would be very hard to call him a liar because what he does is simply take reality and give you another angle to look at it from.

These spiritual gurus are like a distinct type of art. Not everyone is partial to it but certain segments of the population are more likely to find something in it that moves them. You may call these people fools but it's not much different then holders of one political viewpoint viewing the holders of the opposing one as fools. These are just perspectives, there are no absolute right and wrongs here (leaving aside some extremes), because the human experience cannot be narrowed down to science.

The US was formed with checks and balances amongst the branches of government yet there seems to be no checks and balances against government spending or taxation.

The fact that the Laffer curve[1] is a thing leads me to believe that government will continue to tax until the maximum taxation is achieved, or beyond.

Do EEs have to do any projects as part of their curriculum. I'm just an SE by training, but have done some electronics purely as a hobby. A power, resistor, LED circut is bassically my hello world for any electronics project I do. I cant imagine getting through any of my hobby projects without calculating an LED resistor at least 1. Although, at this point I always use the same LEDs, so I could get away with just looking at what I used last time.
There will always be excuses to "wait and see" just as there always have been, going back to the 19th century. After the instant crisis, it will be even easier to make the excuse. It is just more of the same denialism, and just as dishonest as any.
From your comment, it sounds like maybe you're one of the founders I was talking about.

1) Fair compensation, yes.

2) It's unfair to ask someone to have the responsibility for the success of a huge part of your business without making sure they have significant upside if they succeed.

3) Yes, I want a logical hiring process. The horror.

4) Fair. Not "custom negotiated", just fair. The fact that the industry norm is to fuck over your employees should fill you with shame, not be an excuse you hide behind to do the same thing.

5) I doubt I'll take that much, but I like that the company understands that they'll get the best work from employees who are taking care of themselves and their families.

If you're representative of a typical NYC founder, then yes, I'm glad I didn't join a startup.

Sorry that was your experience. Just so everyone else reading this does not get the wrong idea, not all startups are like this. Many are, many are not. 10-year exercise windows are becoming more common. Flexible remote work is also more common (in fact, startup I'm at now as co-founder, we let people work from wherever the hell they want... while my friends at large tech co's have to work out of an office, even if they are allowed to WFH like once or twice a week). And we work hard but let people take as much time off as they need, whether that's vacation or just a day or half day here or there to deal with some family thing.

If you're reading this, please know that not all startups will "bleed you dry". And on the other hand, many big tech co's will!
Show your work, because I flat out do not believe you. Just the fact that you were investing in these startups, acquiring them, and working as a CEO at a unicorn indicates that you have a vastly skewed perception of the typical startup.
This outcome reminds me of an internal memo from my current company, written after a visit to Boeing and Amazon for lessons on digital transformation.

In my experience asking questions on irc is pretty much useless. A lot of times you just get try hard's they don't even understand what you are trying to do that are determined they know more than you about what you are doing. It's just frustrating. If I got a question I typically just sit on it for a day two, and figure it out or ask on a forum. As far as chat, I much prefer something like rocketchat/slack/mattermost because of the embedded data that comes with it. A friend posts a funny YouTube video I just click play I don't have to load open a browser and navigate to the link. When someone posts a link you get meta data with the link so you can decide if you want to click it or not. It's more streamlined that way IMO. IRC could easily integrate this stuff but development of the standard hasn't really progressed that I have seen.
Google at least is insanely profitable. Are Stripe and Airbnb?

Seems to me that there's less risk in the Google stock than the others, because the others need a lot of potential future upside to justify their high valuations absent major profits, and if that upside fails to materialize the valuations will tank (as we're seeing with, e.g., Lyft).
> It seems to me that the primary difference is your ability to reverse course once you have relocated if you aren't the guy at the absolute top. Rather, it's not the switching cost going in, so much as the switching cost going out - it's the same problem you'd face joining Scientology.

Yes, indeed. That is the essential question for Patchwork-based ideologies. However, that is something they actively try to think about

> The answer is that meaning of "efficient" can vary widely depending on who wields power. At our current evolutionary state communalism works up to about 150 people. Beyond that, you need a higher level of government, and historically that means some form of authoritarian government. Since this idea is being proposed by tech-funded billionaires, I can apply a filter to history to glean some insight as to what happens when a group of wealthy sociopaths are given absolute rule over a state. Since I value popularly elected, republican forms of government and free markets empowered by organized labor, I would naturally oppose an experiment that will very obviously lead to more autocracy, servitude, and exploitation by billionaires seeking to bestow feudal fiefs on themselves.

Ok, but how exactly does an experiment lead to that? If that is the outcome that it generates, and people do not prefer that outcome, then they simply will not move there. So, if you are correct in your diagnosis, you have absolutely nothing to worry about. The only thing you do have to worry about is discovering that your preconceptions were not accurate.
So there are actually three tech revolutions going on in parallel:

1) Kuberentes
2) Microservices.
3) AI

All of them are based on open source, and all of them are permissionless (I.e. the startup does not need permission from a big company, e.g. an app store owner).

They also erode the build-in advantages of big tech:

1) Kubernetes erode cloud lock-in on compute/storage.
2) AI is best serve on the edge.

I would say that everything today is up for grab.
I'm not sure that's true for LSD. It's much stronger per mg than other such drugs and as a result tends to be added to other things rather than having things added to it.
Human trafficking is a risk in any scenario, though. It's unclear why that's a salient issue here.
These People Almost Became Famous. Until They Didn’t
Thank you for the comment. I learned a few things about licensing. The main reason I chose GPL was because I don't want someone else building a commercial closed source application based on my app; others can still fork the project and modify it.

I don't intend to release this app on any other platform but others who want to may feel free - I think GPL allows for this. In the end, I don't really care what others do with my app as long as they consult me about what they want to do with it, which MIT is too loose for. If others want to release an app based on mine, they can feel free.

> like addresses in Japan, those are hard!

They aren't hard but indeed easy and very logical. It all started with the Chinese system of starting with the largest geographical entity and going to the most specific one [1]. Later its adopted both in Korea and Japan. It's been the same for dates Year-Month-Day (largest, smaller, smallest). There is no confusion whether it's DD/YY or MM/YY. Funny enough the currency symbol for Yuan and Yen is same character (¥).

So if you understand Chinese, Korean or Japanese language the systems are same.

In Japan the addresses start with the largest geographical entity and proceed to the most specific one. [2]

Well, by forcing the "bad people" into less popular apps they become much easier to identify through other metadata as the popular apps account for the vast majority of the "everyday person" traffic..

I think to get a balanced perspective we should appreciate the dilemma & work done by the govt security people. Their job is to fight the terrorists, pedophiles, forced sex traffickers, and many other "very bad people" - which is easier said than done. In the future WMDs will become cheaper, easier to produce and more powerful, so the issue is becoming more acute. They understandably want better tools to increase their chances of success & reduce likely traumatic failures. They seem to be doing ok with terrorists in the West at the moment, but failing badly with the other categories.

The risk of abuses against everyday civilians are there and I don't have the solutions. But I would presume that the majority of people will trade off a significant reduction to their privacy for a slight increase in physical safety, so that will likely happen. Vastly improving the governance & oversight of the security agencies is one way forward. Otherwise when the next disaster strikes, the security agencies will rapidly make a successful grab for more power.

Morse code isn't binary, it's trinary.

You have 3 signals: dots, dashes, and spaces.

Here's the relevant extract from the wikipedia article on Morse Code:

> Each Morse code symbol is formed by a sequence of dots and dashes. The dot duration is the basic unit of time measurement in Morse code transmission. The duration of a dash is three times the duration of a dot. Each dot or dash within a character is followed by period of signal absence, called a space, equal to the dot duration. The letters of a word are separated by a space of duration equal to three dots, and the words are separated by a space equal to seven dots

Hello, I have tried the Lytro Illum some time back for a week or two.

Other than being very slow, the lens not showing the real focal lenght (instead the equivalent focal length), I found the output lacking in both sharpness and colour. The desktop app for editing was very, very slow (on a quad core xeon), and the worst thing was... no one wants to click your picture to see it animate. You could output a video with a focus pull, but then, who would watch it?

At least for me, the process of taking the pictures, editing and the output being ignored, made it uninteresting for me. Any other questions?
