That figure of 10 to 15 kJ can be very misleading about what it takes to propel something to such speeds. Put into 'TNT equivalent', it would take the entire energy of 50g of TNT to boost a 100g bolt by just 2 km/s. It's difficult to concentrate that much energy per mass in an explosion (which is leaky). To add further, most ASATs (including the Indian test) doesn't use explosives, but make a direct hit (hit to kill) from a suborbital trajectory (one that has much less energy than an orbital interceptor). The boosting comes mostly from fragmentation mechanics.

The satellite will still fragment with some fragments getting boosted up to a higher velocity. In addition, the propellants on the satellite and the kill vehicle might add velocity to the fragments too - though arguably less energy than if it was TNT. So, previous studies on US and Chinese ASAT debris cloud can be considered for a fair assessment. The Chinese test was at a higher altitude of 865km and US test was at a similar altitude. 'Gabbard plot' of these debris show the maximum altitude to be only around 3900 km for both tests. There could be untracked particles at higher orbits, but remember that the velocities of the debris is a random distribution (not sure which one) that tapers at extreme values. Odds of any debris crossing geostationary orbit is very low.

There is one additional significant point to consider. Boosted orbits mostly retain the altitude at interception (it's the diametrically opposite part of the orbit that gets affected). This is evident from the Gabbard diagram, where apogee and perigee plots intersect in cross shape with a horizontal line at the altitude corresponding to intercept altitude. This means that most debris come down to atleast 300km. Since the drag at this point is significant, the apogee (maximum altitude) of the debris would decay rapidly - thus mitigating risk to higher satellites. With that odds, a debris crossing geostationary orbit could more likely be from some previous in-orbit explosions than from any ASAT test.

While you are right that having and endorsement is a hard requirement, if seems BYU makes it as easy as they can for a religious-backed university to get it. I found nothing so far that says you must pay tithe or must attend some services so you’ll have to provide sources for that.

I think the biggest thing you understate in your post is the percentage of students who attend BYU and are active Mormons. Figure I found says that this number is close to 98%! I feel bad for your situation, but you should have switched universities when you discovered your atheism before things got that bad.

Simply put BYU is not for non-religions and non-conservative people. With so many other great choices in the US and the world it feels disingenuous to once again attack Mormons for simply trying to do their own thing.
I think it's funny how "not possible" or "not even remotely likely" answers are just dismissing the possibility of this being debris from low earth orbit.

Sure, it's unlikely. But unlikely bugs do happen in computation, too. We _cant_ know.

> It is CRAZY expensive and the pricing is not really transparent - in our case we had 20 MB of data, 4 1000RUs collections and multi-master write in Western and Northern Europe. The monthly bill? 300 EUR even though Azure Portal was displaying 1/6 of that cost - apparently for multi-master you multiply by the number of regions + 1 (2+1 = 3) and for geo-redundancy only by the number of regions (2), thus the 6x higher cost. The result of that was that we were paying several times more to manage 20MB of data than for all the remaining data - hundreds of GB.

I get your point and they should definitely fix either the cost calculation, or paste a disclaimer for multi-region pricing. But I want to (sincerely) ask how you could assume that multi region would _not_ cost more than single region.
>Couldn't this same logic be applied to everything attributed to US intelligence? Maybe someone else fabricated the CIA Vault7 leaks, because surely the CIA is too smart to get caught.

No, because documentation is easier to corroborate and harder to deny (and indeed the CIA doesn't deny vault7 is theirs).

A string of IP addresses and a narrative, on the other hand... yeah that's rather more circumstantial.

If tomorrow there is a leak of Russian documents corroborating the American story that arent obviously fabricated then I'll take that as clear evidence that it was true.

>You're willing to go out of your way to believe in mass delusion or conspiracy within the media and intel communities to avoid believing that maybe Russia did hack the DNC.

I don't think that clear attribution of hacks is ever really possible and whichever narrative takes hold will generally be believed in perpetuity.

I think the intelligence agencies aren't above a little self delusion, no, and I also think the fact that it's unlikely evidence will emerge to corroborate or disprove the hypothesis (hack evidence disappears very quickly) makes self delusion, where it does exist, a little easier.

The "Russians hacked the power plant" story demonstrates what kind of blow back happens when they do drink their own kool aid (zero) and serves as a clear examppe that they are perfectly capable of self delusion when it comes to the topic of Russian hacking.

>Or maybe Russia did hack the DNC and Assange is the only one lying about their source?

Anything is possible. However, it's worth noting that the "assange is a Russian spy" story is similarly convenient to the "Russians hacked our power plants" and it similarly rests on extraordinarily weak evidence.

The spirit of McCarthy lives and it's way more pissed about the collateral murder video getting out than it is about the murdered journalist in the video. Obviously.

> Why have a monopoly on DNS?

Because for now it's the only mechanism that we all use to do lookups. Magnet links are too tedious to give out over the phone - domain names are catchy and memorable and can be easily said over the phone. This is why people brute force Tor .onion addresses to something memorable, like Facebook's .onion https://facebookcorewwwi.onion/ And I suspect if you start using magnet links that people will find a way to make them memorable too
Usually when you're working on the scale of operating systems, you have people focusing on particular areas e.g. kernel teams, networking teams, graphics teams etc and you also have their corresponding test teams. So no one person usually even has understanding of the entire source code.

Rust does have a procedural macro system which can be used to do these things. Surely actual procedural macros are better than hacking the template system to generate custom code, which is the typical approach in C++.
I can see some of these stats in action. Where I live (Bay Area) Lyft is always more expensive (I typically check them both), sometimes by a lot. While in Manhattan I find Lyft cheaper about a third of the time. So no surprise I take more uber rides.

Yes - on their operational security.

Uber IPO filing: Biz model relies on misclassifying drivers as contractors
From the original paper (http://cnnlocalization.csail.mit.edu/Zhou_Learning_Deep_Feat...):

"A class activation map for a particular category indicates the discriminative image regions used by the
CNN to identify that category"

So, it's mostly what you said, but the maps you get are specific to the particular trained network you're using; the class activation map tells you, for a given network, for a given image, for a given class, which image regions did that network consider relevant to that class.

For learning more about interpreting neural nets I would highly recommend the posts on distill.pub; https://distill.pub/2018/building-blocks/ and https://distill.pub/2019/activation-atlas/ are probably most pertinent.

Hi Marcel!

I'm thinking of something that would be a lot like Smalltalk, but with strict separation between program and metaprogram. (In the spirit of Alan Kay's notion of fences between metaboundaries). The IDE would run in a separate process from the program, and attach to the program via operating system debugging facilities.

I think most of the problems with Smalltalk can be traced back to its origin as an operating system and the mingling of the program and tools for writing the program in the same image. Eg, shrink scripts for deployment.

Let’s look at those reasons.

We will have a monopoly on X because that’s what we all use and that’s how we’ve always done it. No alternatives are needed.

- Well does that reason work well in any other area of life?

“Too tedious to give over the phone” - usually you give a business card or email a link of sms a link. And all you can give over the phone is

A easy to pronounce domain name
With no ambiguities
With a common tld

And even then, ALL you can do is give out the homepage. Any other resource deeper on your site — and you don’t use your phone do you?

Do you use the phone to give out the URL of an article on nytime.com or video you posted on youtube? Thus the VAST MAJORITY of links you don’t give out on the phone.

If you DO want to give something out on the phone then people can just google for it. Or use another search engine

DNS is literally the search engine with the least features. Google lets youfind any resource within your site, and even lets you misspell stuff. How is that not strictly better?

To summarize:

ICANN monopoly is replaced with search engines, which do far more than find your homepage from an exactly spelled domain

Magnet links can be memorable via search engines

Links are usually NOT to the homepage and are not really human dictated anyway (eg youtube)

Tunnelling an internet resource address through a phone conversation is pretty bad anyway, but better to allow innovation in it like searchh engines or just text the link afterwards (as most people do)

Links are usually replaced with nice-looking thumbnails and titles in UI

In Javascript and other languages, it’s no big deal to hold magnet links in variables.
What I see people missing here is the transportation aspect - land is only scarce in San Francisco if it’s permanently limited to a 7 by 7 mile square. Transportation increases the viable size of where you can live to access the city. So make land less scarce by building fast transit from other places.

That all said, it’s also a joke to think that SF uses its land wisely. What’s at the 24th st mission BART stop? A 1 story McDonald’s, what a great use of prime real estate to protect a treasured cultural relic.

Yes, I do know why I thought about adopting a dog. It's because I love dogs, and have wanted one since I was a kid, and a really cool dog happened to walk past my window at the time while I was at talking to my friend.

I never Google dog photos or anything dog related really. I have no real reason to. Also, all the ads are see are usually either finance related or tech related. The huge influx of dog adoption adverts was most certainly an anomaly. I dismissed it the first time, but the second time, it was harder to put it down to chance.

I could be wrong, and maybe they aren't listening in, however at this point, I can't say with certainty that they're not. My suspicion is officially raised!

Any US citizen interested in zero equity seed money from the US government should investigate SBIR (of which this is the NSF component), a program overseen by the Small Business Administration, but run through the departments. (You end up paying in other ways — but you should be aware of it as an option.)

Every US government research program must provide 3% of its R&D to small businesses, with the goal of seeding American innovation outside of major conglomerates.

Personally, I view results driven government seed money as a viable answer to many questions the US faces — but it requires we pull together behind a vision of free people engaged in small commerce, something the US left wing seems to vehemently oppose.

I’m a capitalist, though: I believe the best way to cause human flourishing is expansive commerce coupled with individual freedoms, and suggest anyone disputing the social value of that show me a system that’s uplifted as many minorities out of poverty as, say, McDonalds franchising.

This title ('The infamous “AI gaydar” study was repeated – couln't be reproduced') is very incorrect; it does not correctly summarize either the linked article or the actual paper (https://arxiv.org/pdf/1902.10739.pdf) that the article is discussing.

From the abstract on the actual paper:

> Using a new dataset of 20,910 photographs from dating websites, the ability to predict sexual orientation is confirmed... While demonstrating that dating profile images carry rich information about sexual orientation these results leave open the question of how much is determined by facial morphology and how much by differences in grooming, presentation and lifestyle. The advent of new technology that is able to detect sexual orientation in this way may have serious implications for the privacy and safety of gay men and women.

So, the study was repeated, and could be reproduced. However, it's still not clear if there's any merit to the facial morphology hypothesis, vs. the (less worrying) hypothesis that the models are just picking up on differences in grooming and presentation.
