There are plenty of sats that have just stopped working, even broken apart, for unknown reasons. Telling the difference between a defect and a meteor impact is mostly impossible. Lots of spacecraft have just stopped working for unknown reasons. Until we start inspecting every failed satellite, as we do aircraft, we won't really know.

And note where the 2009 collision happened: over the arctic. This was one polar orbit colliding with a near-polar orbit, right in the danger zone I mentioned above.

this is the same kind of situation in Denmark, I've lived most of my life outside of Denmark, after I cam back in my early 40s I went to the Doctor and said innocently "well I guess I'm getting to that age now where I should have an annual checkup." There was no explaining the concept to him.

Looking over some basic info, I'm kind of surprised that I haven't tried this before. This is because I've played around with Jungian active imagination techniques and IFS.

In the first case (and I haven't really researched this deeply) one way is to enter a recent dream world while awake and "allow" it to play out, talking to the people inside and letting them respond. The approach you decide take with the people is somewhat circumscribed by Jung's archetypes, where you may encounter a guide of the opposite sex, embodied neuroses, other advisors, and eventually connecting with a "Great Man" or God-man figure (the "Self") who is your ultimate truth or something and lets you truly grow (don't think I've gotten this far). According to Jung, the archetypes you encounter are part of the human unconscious mind the same way that eyelashes are part of the human body, and they both give rise to and provide a key to interpreting human religion and spirituality.

In IFS, you meet or summon "parts" of your psyche that may be malfunctioning or acting up because of past trauma or defense mechanisms, getting to know them and healing them. Once they're healed they can help you out, tulpa-style. But the emphasis is on letting them take shape, not creating them. In IFS, you have to be able to connect to your core, non-judgmental spiritual "base" (which is called "Self" in IFS) before talking to the parts.

So this leads to my questions about tulpamancy. How "freeform" are the decisions people make when creating tulpas -- do you see enough commonly shared traits between people's tulpas that would make you think you could "systematize" access to them like above? Do you think that the tulpas are always there in the mind in some form and you're just bringing them out or changing them, or are you actually casting them into existence? Do people ever make mistakes with their tulpas that cause them to be malicious rather than benevolent thoughtforms? Do you have any personal opinions about Jung or IFS?
That seems like an _extremely_ high rate of failure. Are these embedded spot lights or something?
Ah, you're right, I didn't think it through. It does feel like there must be a way to play with the bits so that you can retrieve it in a single pass, though - that'd be a much more interesting problem :).

You're wrong. Remember that XOR works on individual bits. If what you're saying was true, then swapping bits that are both set to 1 would also fail, which means this algorithm wouldn't work at all.

Edit: Ignore this post, I misread the original post as saying swapping the same values would fail.
I don't see how the problem corresponds to erasure coding.
Typically in erasure coding you know the locations of the erasures.
Here, you don't know the location.

How Should We Read?
I've known of XOR tricks since the 80s, when you would "undraw" a graphic on the screen by redrawing it with XOR. But only recently I learned that the implementation of multiport memory for CPU caches and the likes often uses a design based on multiple storage copies and XOR to get the last valid written result. Amazed that the CPU's cache is doing that kind of trick all the time just during regular code execution.
The problem is: It's not a viable metric in any way, meaning, it's not a metric at all. It's just another incentive for some "alternate reality".

Depends where you're coming from. Visitors from other EU countries (and the UK, for now) will use their existing data plan, since the EU enforces free roaming amongst member countries. If I was coming from elsewhere, I would likely do the same, unless I'd be there long enough to justify buying a local SIM card.
In 2015 I did several months of due diligence in this market - price comparison for diagnostic imaging - before concluding that it wasn't feasible to build the product we wanted to build. This new law provides the data that we were unable to access (at scale) on our own.

From the data we did get our hands on, I remember seeing price differences like $200 vs $4k for the exact same procedure. The low cost provider was usually a private practice radiologist in a small shopping mall type retail location who ran a very efficient, low overhead practice. They were terrible at marketing and ran discounts for volume from certain channels. They were only open Monday to Friday from 8am to 4pm, read times could often (but not always) be slow, they handled the least complex cases and no emergencies. Cash pay up front from patients resulting in no/minimal collections. The high cost provider was usually a large University affiliated medical center who ran a less efficient, high overhead radiology department but who also, in their defense, had to handle more complex cases as well as be open 24/7 to service one or multiple emergency departments with faster read times. Lots of fighting with insurance companies for eventual reimbursement. Lots of bad debt that went to collections and had to be written down.

If you pay University prices for a simple MRI you are effectively subsidizing the ED admit who needs a complex imaging procedure in the middle of the night. If consumers start to shop for MRIs the way they shop for airline tickets - which they probably should - one downstream effect will be to remove billions of dollars of "subsidies" from the most well-resourced radiology departments in the country. If I remember correctly the diagnostic imaging market was something like $150 billion/year in 2015, and probably even bigger now, i.e. plenty of potential fat to cut.
It wasn't rushed, the science was ready to go early last year and all they did was accelerate the first trial phases, the Phase 3 trials went quickly because infections were so widespread.

That there are multiple candidate vaccines targeting the spike protein without using the virus directly is strong evidence that the science was ready (using mRNA, viral vector and other technologies).
> As I got closer, though, I started to believe that if the rumor was true, I would never have been able to justify to myself that I had stayed at my desk and turned down an escape from the pandemic.

I just recently got my first shot of the Moderna vaccine last week. When I learned that I would be getting it, I went through the same euphoric excitement the author is describing. Then it slowly dawns on you that this is simply a bandaid. Something to stop the massive amounts of deaths. It's not going to miraculously end everything and make the world go back to normal. There is no "escape". You're not going to be hopping on flights, vacationing, and going to bars again any time soon.

This is a real mistaken mindset that I think people are going to have to come to terms with. The vaccine is not a silver bullet. It doesn't just make the virus magically bounce off of you like a force field. You will still get infected if you are exposed, and can very well still transmit it. The vaccine simply keeps you from developing severe disease.

We (the human race) have a long, slow, painful slog ahead of us to return to anything even resembling what things were like in Fall 2019. The virus is going to become endemic. Overall population vaccine uptake will most likely look like Flu vaccine rates (<50%). And that means life will never be quite the same.
Lol. Well, that's why I ended with:

> But at that point, I'm interviewing for someone who has passed a data communications class.

This is basic data-communications stuff. But there's a reason why data-communications isn't exactly a commonly taught subject: its niche and not really generally applicable IMO.

My main point is that the XOR-trick is a decent data-communications question. But I don't know how generally applicable it is to other programming fields.

> On the other hand, the goal is also to increase the vendor lock-in, by providing everything inside their garden walls, so that people keep going further into giving up any side channel and into putting all their eggs into the same Github basket.

That's also true but where do you draw the line with vendor lock-in and convenience?

If you use Google's mailing list service then you're locked into Google. What if they decide to drop that like many other services in the past?

If you use a self hosted forum / mailing list instead, the repo owner is on the hook for setting up and configuring a server along with potentially registering a domain name just for that aspect of an open source repo. With something like Discourse that could be like $20 / month + domain just for 1 instance of it.

If you decide to use Discord or Slack as a side channel for casual chatting or feature requests then you're locked in there too and there's no persistence (at least not with Slack) or SEO discoverability.

That and with any of the above solutions chances are folks will end up reporting bugs in those side channels which means someone needs to go back and write them up as proper issues, often times that'll be the repo owner. Plus now all users need to jump through hoops by registering on those external platforms to give a feature request on a project on GitHub.

I hate the idea of vendor lock-in but at some point integrated platforms make sense because the alternative is worse. As a developer I really like having my code, CI, issues and a place to chat all in 1 spot. If GitHub dies, that's fine there's always Gitlab. If Gitlab dies, there's always Bitbucket but at this point the developer community would likely revolt and come up with a new solution.

This does not match my experience. I bought 12 Philips Hue bulbs in June of 2013. They run an average of 15 hours per day across three color/brightness profiles, and in these 7.5 years only one has failed.
Because it means that if you buy a fixture with built-in LEDs and a more reliable power supply it'll be a very reliable light.

The problem is that trying to cram a tiny power supply and a hot LED chip into a small bulb without a good heat sink is inherently unreliable.

Especially if you put that bulb into a completely enclosed light.

I went in 2018 and spoke with some of the employees working there. It’s very true. Almost no one lives in the city proper anymore; everyone commutes from outside.

On a related note if you decide to go: the city proper is very much a tourist trap. The food is not good and everything is overpriced. If you decide to go I wouldn’t spend more than a day inside the city itself. I had a much better experience taking the water taxi to the surrounding islands. The food is better, people are nicer, it’s way less crowded and the sights are just as good.

In Ireland, there were strong norms in favor of marriage and strong taboos against divorce, and all those other things.

There was also a semi-hidden system of forced labour for those women that did have children out of wedlock. The "mother and baby" homes. The amount of abuse involved was horrific and the country is still untangling and confronting it decades later.

Be wary of changing a system where the abuse is borne silently because there is no way out for one that makes it visible and thinking that is worse because just now you can see it.

Divorce rates are on their way down in the West. The transition period is definitely rough, but eventually the cultural norms adapt.

I would be interested to see if you canvas the views of Bangladeshi women on the comparative systems.
