These are relatively cheap prototypes. No engines, just the fuel tanks and body. Cheap stainless steel, fabricated in weeks. If this was Boeing, it'd set them back years. The whole idea is to crank out a steady stream of cheap prototypes to iterate design ideas and fixes rapidly.
By commercial, I mean commercial users using hobbyist spectrum. These would interfere with the hobbyist use. Instead, if you're a commercial user you go to your RSM or whatever and licence a bit of spectrum.

If you want to design and build something meshy, go for it. If you're licensed and obeying the rules, you can use the ham radio spectrum for your experimentation. I'd encourage that. But when you want to take it commercial by selling access, licence some spectrum to use for it and then you don't have to use callsigns, can use encryption, etc to your heart's content.

The purpose of the ham band allocations is to be a place where people can experiment with radio (or ragchew if that's more their thing), they're qualified to some degree so are less likely to interfere with others doing the same, and they're not being stomped on by companies using it as a space to do their ISP wireless data backhaul or whatever.

By "build a meshnet in the Ham radio spectrum and sell access" you're taking something that's a public good (with some conditions) that others had access to and reselling it, making it harder for others to do the same.
Both guesses are wrong.
Unfortunately the wayback machine didn't cache the CDC's page on guidelines until recently, but an article in US based Vox from February says:

https://www.vox.com/recode/2020/2/13/21128209/coronavirus-fe...

"Currently, the Centers for Disease Control and Prevention (CDC) advises against people in the US using face masks because most people who aren’t trained medical professionals may not know how to fit them properly, and the risk of exposure in the US is so low to begin with."

Many people spoke out prominently against wearing masks in Germany, including Christian Drosten [1], der Spiegel [2] and Robert Koch Institute.

Yes, if you read between the lines the statements were often hedged, and not strictly speaking wrong: you should not wear masks (because healthcare workers need them more), masks dont protect (you) from coronavirus, there is no study that shows masks protect against the novel coronavirus (specifically). The general public just reads that you should not wear masks, period.

Some people experienced hostility for wearing masks in public. You can get laughed at or coughed at. Asians wearing masks are avoided like they have the plague. And an old lady sneered at me (no mask) for keeping the required 2m safety distance in the supermarket, as if I was an idiot.

That being said, most people are behaving exemplary and respecting physical distancing, and I hope the attitudes regarding masks will shift with time.

This is an early manufacturing path-finding test article and test, not a test article and test designed to validate that the system is safe. The procedures, design, manufacturing techniques, and everything else are still being developed and certainly haven't been validated yet. Failures are expected.

It is a good thing that there is nothing inherently wrong with the design, just because that would mean more re-design work for SpaceX. A procedural issue (possibly this failure), a manufacturing defect (MK1 failure), a failure due to a temporary hack (SN1 failure), etc are all understandable errors and easily fixable at this point in time.

Starship isn't really being driven by the "boots on the moon by 2024" push by the government. Starship is a private venture being developed on their own schedule (and with their own money).

> Out of curiosity how come you have such detailed familiarity with the topic?

I developed the typical Lyme symptoms after spending a lot of time outdoors in a Lyme area and removing ticks from myself several different times. I tested positive for Lyme under the relatively strict CDC criteria from a trusted laboratory. A 28-day course of Doxycycline changed something, but the fatigue and general malaise stuck around. I've spent the next decade consuming every bit of research I could find on the topic.

I'd love as much as anyone for this already FDA-approved antibiotic like Azlocillin to be a miracle cure for my problems. I would gladly welcome properly structured RCTs. However, I've learned to be extremely skeptical of antibiotic therapies for Lyme. Patients who self identify as having "chronic Lyme" are notorious for holding strong beliefs that antibiotics improve their condition after reading about hidden spirochetes and undetectable infection theories for years, but double-blind studies show no benefit.

I think the much more likely explanation is that Lyme can trigger long-lasting alterations in the body somewhere, even after the infection is eliminated.

Sadly, the topic has become so political that mainstream researchers won't touch it. Now that "chronic Lyme" is so closely intertwined with the alternative medicine community, anyone who denies the persistent infection theory is treated as if they are denying the persistent symptoms of sufferers. That couldn't be farther from the truth for me, as I suffer the symptoms myself.

The topic is so politically charged that I only use my pseudonymous alternate account for discussing it online. I've had chronic Lyme sufferers dox me and send vaguely threatening messages in the past, just for discussing the research online. It's no wonder that more researchers don't want to investigate Lyme disease.

noisy channels have information capacity.

reports are that the loss of sense of smell and taste are severe, sometimes total. things 'taste weird' or have no taste at all. it doesn't matter what the person's sense of smell was before - the magnitude of change reported by a noticeable amount of individuals in a geotemporal cluster is enough to trigger an alert. the key is 'noticeable amount', so you measure background noise first.

This is not bad, this is how progress is made in this industry - These are not fully operational prototypes, they are parts fabricated purely for the purpose of testing the behavior of designs far beyond required limits, the purpose of these tests at this stage is to collect useful data not prove designs.

> I wish people would qualify their “Apple Hate” every time they mention it.

Sure, let me do that: Apple is a corporation and it is stupid to believe that they care more about you than making profits.

This applies to any corporation. I've particularly noticed that the US citizens are increasingly buying into this propaganda that corporations can better protect their rights than a democratically elected government. And that is just sad and dangerous. We should be campaigning for our privacy rights directly with the government, and not just hope that some corporation will act benevolent towards us.

(And it is not a coincidence that this "news" came up in the social media feeds when the [news about exploits that granted unauthorised access to your camera through Safari is going around](https://www.ryanpickren.com/webcam-hacking-overview).)

The issue here is that instead of adding a physical switch to disable the microphone and camera, Apple is again asking its users to blindly trust it. We just have to take their word for it that it will work. They can always blame a bug in the firmware if somebody finds a way to exploit it tomorrow ...

(Note: I mentioned the Safari exploit only to point out that there is some negative news which obviously a corporation would like to bury with some positive publicity. It is commendable that Apple paid the discoverer a nice bounty and will be fixing it soon.)

I'm fascinated that, as far as I can tell, there's a lot of disagreement here about whether this is "mumbo jumbo" or not, when nobody is addressing the major aspect that differentiates reiki from other non-traditional medicines -- which is that it is based on touch.

We're social animals. I've never had reiki but I have spent some time in hospitals. You know what you NEVER get in a hospital? Someone touching you in a way that isn't associated with a (usually painful) medical procedure. There is literally no aspect of hospital life that accommodates human sociality. So the idea that someone comes in to your hospital room and touches you gently and that makes you feel better? OF COURSE it makes you feel better. In the same way that therapy dogs make you feel better. It's social touch. It's pleasant. It addresses an incredibly deep-seated need in the human psyche, one that if it is not met eventually results in - if nothing else - significant mental health issues.

So it seems to me that the right scientific study to do here is not whether reiki improves on (say) chemotherapy outcomes; it's whether any sort of touch therapy, including therapy animals or just regular hugs from family, results in improved outcomes.

>Even the other treatment outlined in this blog post (disulfuram) has an open study that is still looking for volunteers. That tells you a little bit about the level of need (modest, but not zero) and the disinterest of the patient community in advancing science (you can draw your own conclusions here).

This shows a lack of empathy. Patients are either too sick to travel or lack the money. And how would they hear about this trial when so many doctors, like you, deny the severity of the problem? But the main reason is that patients don't need the trial, Lyme communities are full of people taking disulfiram on their own and finally recovering.

It is likely test like that was planned long in advance and peoples schedules were planned so that right people were available for the test.

Including a counter in each UDP packet does not make ECB mode equivalent to CTR mode.

Let's assume the counter is at the start of the packet. An AES block is 16 bytes, so the counter ensures the first 16 bytes of ciphertext are unique across packets. But any patterns in the remainder of the packet are preserved, within and across packets.
I think that PostgreSQL itself is great. However, the developer client tools (pgAdmin) leave something to be desired. The old pgAdmin3 was fine, if lacking bells and whistles.

Can anyone recommend a good client for PostgreSQL?

Hi Team,

I hope you and your family are staying healthy. I am reaching out on behalf of LogN (https://www.logn.co/) as I saw on News.YC that your company is looking for software engineers.

We provide contract engineers in Central America (timezone: PST+1, EST-2). Three of our engineers are available to start a new engagement as soon as April 1st. They just rolled off of another long term project for a company that is funded by Benchmark Capital. Here are their resumes. (https://docs.google.com/spreadsheets/d/1A4nHUDWcHr9F4fVxYC0b...) They have also worked with several US-based startups and big enterprises. Please let us know if any of them is a good fit for your needs and we can help schedule a zoom interview with them. You can find more information about our services here. (https://www.dropbox.com/s/pu7f2o3x2yvi8vn/LogN-Services.pdf?...)

> This is what capitalism is in its essence - a complex decentralised pricing mechanism where every human's choices is taken into account on the free market.

That's what capitalism is in a world populated by Homo economicus. We have to deal with it in a world populated by Homo sapiens, who are notably clumsy at separating capital allocation concerns from social dominance concerns (when we even bother to try).
We've had 10 years of frothiness in venture markets. Many employees under 30 don't even know what a downturn looks like. They're used to high pay, constant calls from recruiters, and venture capital flowing into their companies. Even the companies who flop, no big deal, just go down the street to the next company. I worry that that generation is going to have the most difficulty with these changes. They'll wonder why things are contracting, why difficult decisions need to be made, can't we just wait this one out...?

I've never seen anything like COVID-19. I lived through the dot-com bubble, watching friends who want from an IPO party to crying and packing up their car back to Iowa within 6-months. Tech contracted and survived. Then there was the 2008 financial crisis. In that case, the damage was spread out beyond tech centers. Capital markets dried up and life seemed very uncertain for awhile.

With COVID-19, we went from extreme prosperity to an unprecedented shutdown of global economies with massive uncertainty as to how long this will last. Every business will be affected, the vast majority of them negatively.

I really wonder whether everyone is prepared for what it means to live in scarcity instead of abundance.

It doesn't matter for coding or functionality, but it is nice when you're manually eyeballing the results of 'SELECT * ...' statements or browsing tables with something like Navicat, or looking at schema dumps - to have your fields ordered in some way that makes sense to you, rather than strictly in the order they were created.

Sure, you can list the fields in the order you want in a SELECT statement, but that's tedious - it's handy to have something reasonable in the table definition.

I always used to be a bit lackluster about the idea of deploying smalltalk applications for a similar reason - too powerful introspection and debug tools that are too easy for an end user to open accidentally, and be confused by.

But now, switching between a terminal that uses shift-ctrl-c for copy, and outlook/o365 in chrome, I often accidentally open developer tools in my email "application"... And wonder how much better we might be off with a solid smalltalk (or strongtalk, self) system -- than the current mix of crappy web apps and crappy electron behemoths...

I should note that it's generally possible to strip out/hide and disable most of the introspection stuff from smalltalk applications and ship more end-user style applications.
