Radio and television, I think. They were a medium for non-literates to also participate in learning and exploration, in a way they couldn’t if the only way to do so was through reading.

How can one make any functional claims of value without some functional testing? What am I missing?
I’m sure its cool they’ve been able to design and 3D print a complex structure - however, the company blog appears to only link to additive manufacturing companies: I couldn’t find a subsequent link where this engine has been (even) ground tested, demonstrating basic validation of the design in test / fire conditions: till that happens, this is just (imo) a cool looking untested, unvalidated design and therefore, untested, unvalidated algorithmic design..
None of the reports covering this even mention any testing, or any anticipated testing. Is it an art piece?
Based on his analysis, it does seem like Musk really has succeeded in shooting himself in the foot. There was a recent decision, again covered by Matt Levine, in the Delaware Chancery, where (from what I can understand), in a similar situation, the Chancery compelled the buyer to complete the purchase, notwithstanding their attempts to exit the agreement [3].

'The FDA’s eventual decision to ignore the advice of its advisory committee and approve the drug, it says, was based on aducanumab’s ability to lower levels of amyloid plaques in the brain — protein clumps that some scientists think cause Alzheimer’s.'
...
With aducanumab, the agency has shown that it is willing to push the paradigm to a broader set of people. One reason that decision has attracted criticism is that decreased levels of amyloid plaques are an unvalidated and contentious marker of a drug’s activity.
In large trials of other Alzheimer’s drug candidates, amyloid lowering has not led to cognitive benefits, and this has made it a sticking point for researchers.' [0]
Then, Thud, the game loosely described by Sir Terry Pratchett in Thud!
It is a membrane keyboard, not mechanical, but it works well for me. The numpad is separate from the main keyboard, so that works well too.
It is wireless - which is a good thing and a bad thing. Good because it is convenient, bad because unlike the logitech M series, if you lose the usb radio, I don’t think you can order a replacement, so the keyboard becomes useless.

The website of the Nintendo founder's family office. It..is just beautifully designed, and a homage to the original game consoles and the entire art form of PC gaming when it started.

But if it comes down to it, I’m actually completely ok with such an approach.
How is this any different than mandating the small pox vaccine, or the polio vaccine?
The vaccine dramatically lowers the probability of a severe infection; reduces the burden on healthcare systems - which in, in many countries apart from the US (for instance, Canada) is a public good. And therefore enables hospitals to provide care for patients with other diseases; patients who need urgent surgical procedures.
Even where there is private healthcare, it still is a public resource.
One possible symmetric response to people who refuse to get vaccinated is to deny them access to healthcare if they get a covid infection and need medical care - But I think that is far more draconian and inhumane, and is arguably more akin to medical apartheid, than denying those who chose to remain unvaccinated (without broadly accepted medical reasons) access to public goods when they do not accept their responsibility towards public welfare.
Wish you and yours a fantastic year ahead!
Another thing that is unique to large corps (Reliance, Amazon) is the network / conglomerate leverage they can bring to bear. Hina Khan's argument against Amazon resonates here too.
To quote from the work [1] that (I think) put her on the tech-regulation radar:
'This Note argues that the current framework in antitrust -specifically its pegging competition to "consumer welfare," defined as short-term price effects -is unequipped to capture the architecture of market power in the modern economy. We cannot cognize the potential harms to competition posed by Amazon's dominance if we measure competition primarily through price how integration across distinct business lines may prove anticompetitive'

So I’m imagining a solid block of iodine (it is in cold space), and when the engine needs thrust, some current from the solar cells is passed through a heating element to drive sublimation + lots of complex rocket science that I do not know of.
If you are referring to the noble gases, I don’t think they are cooled to the point of solids; just high pressure liquids..
I am learning to design PCBs, and while I have a basic understanding of the components (viz. resistors, diodes, transistors, etc) as the board gets populated with more components, (consider, for instance, an arduino dev board), it is just very challenging to build a model of how the entire board works - the logic etc.
Further, a good part of modern microcontroller boards is dedicated to (I think), power delivery and conditioning.
Getting a functional model / representation of the entire board in my head has been a huge, as yet insurmountable, challenge.
Are there any good games that can help me wrap my head around these concepts?
Switched to iPhone after being on android all this time (with a brief dalliance with Microsoft phone on the lumia 910, which I think is still one of the best smartphone UIs) for the same reason as parent.

Why should my citizens give up basic development and quality of life when the prime drivers of global warming most recently withdrew from the Paris agreement in a fit of right wing nationalistic self interest, because they felt their lifestyles / livelihoods were threatened? India and China have shown far more maturity than the US in sticking with the agreement and continuing to work with the world to find a path.
CN is where most manufacturing is, even though consumption is in again the rich nations. [2]
Yes, the impact of global warming will be disproportionately borne by counties such as India and pretty much all of Africa if the worst of climate change isn't mitigated. But I am screwed anyway if I cut my development to meet emission targets. So I'd rather develop rapidly to build the economic and infrastructure wherewithal to withstand the climate change disruption; the biggest producers / consumers of the carbon economy are still driving climate change [3], and those guys (including Australia) aren't too keen on actually making the painful decisions they need to. Why ask me?
The US automobile industry still promotes gas guzzling trucks. Ford has completely stopped selling sedans in the US, because sedans, though fuel efficient, are not profitable. Because the US can't be arsed to extend / demand / price for the fuel efficiency standards for trucks. And John Kerry has the temerity to come preach to the rest of the world.
China is already the world's largest manufacturer and consumer of electric vehicles. They have a remarkably impressive mass rapid transport system. They are doing more than the US and EU are, at this point [4]. Let us see the US invest in mass rapid transport; in rail networks. I've lived in the US for almost 10 years; while I get that some parts of the vast country are too low in population density to support or justify mass transit, that's simply not the case for the ACELA corridor, or the large cities and economic regions on the coasts. These are hard social changes, and none of the OCED countries have demonstrated the necessary will-power and willingness to accept some disruption to their lives; don't ask others do to what you aren't willing to do first.
The EU has started to some limited extent, but there's barely any carbon intensive manufacturing left in the EU: all of it has been outsourced to CN and other developing nations. Once I see them start imposing a carbon consumption tax, then I'll accept they are actually serious about climate change. Come preach / pontificate to me then, or ask me to make my own hard choices in terms of such trade-offs.
I didn't create this problem. It is my shared responsibility to solve the problem, because I have benefited from the carbon powered technological and trade innovation. But don't expect me to assume the lion's share of the burden while the countries that drove, still drive climate change, pay lip service to making the hard choices they need to be doing as well. :shrug:

Edit: Clarified and expanded on a few points, corrected spelling & grammatical errors.
I still remember a hard-bound, deep blue coloured (roughly) notebook sized book that had these amazing DIY projects for space, including a rover etc. I don't think I could ever make the more complicated ones- they required woodwork etc which I simply didn't have access to as a child. But they helped me dream and develop an interest in making stuff of my own, and they are one of the reasons why I still love tinkering.
I wish I could get hold of that book once again, but I can't even recall it's name!

Ithaca is just such a wonderful place to live, winters included!
The tea can be salty (J&K), incredibly sweet with thickened milk, with spices (cardamom, ginger among others), brewed with bhang (wet cannabis leaf), boiled with milk, leaves spices and sugar at the same time, or with each ingredient added in some specific order..
The possibilities are limited only by one's imagination, and my imagination often falls short of reality. :D
As you allude to, I've also experienced something like this & lost someone close. I know how heart-wrenching it can be, and how debilitating it is to just stand by and watch.
The very best to you & more power to the two of them!
The front end definitely can be much much better; but the issue is very simply there are not enough tickets to match the demand.
"From 29 tickets booked in a day in 2002, it has reached to 13 Lakh tickets a day as of now. It is reported that the IRCTC system is currently capable of booking 15K tickets a minute online and can handle 3 Lakh concurrent users to handle any surge in demand." [1] (13 lakhs is 1.3 million)
"Of the 15 million passengers who climb aboard one of 8,520 trains each day, about 550,000 have reserved accommodations. Their journeys can start in any part of India and end in any other part, with travel times as long as 48 hours and distances up to several thousand kilometres. The challenge is to provide a reservation system that can support such a huge number-regardless of whether it’s measured by kilometres, passenger numbers, routing complexity, or simply the sheer scale of country. " [2]
If anyone has better references on the frankly astounding technical accomplishment that the CRIS Passenger Reservation system, please share.
"Passenger Reservation System (PRS): A nationwide online passenger reservation and ticketing system, developed and maintained by CRIS, was developed in C and Fortran on a Digital OpenVMS operating system using RTR (Reliable Transaction Router) as middleware. Also known as CONCERT (Country-wide Network of Computerised Enhanced Reservation and Ticketing), it interconnects the four regional computing systems (in New Delhi, Mumbai, Kolkata and Chennai) into a national PRS grid. It allows a passenger anywhere to book train tickets from any station to any station. PRS handles reservations, changes, cancellations and refunds, reserving over 1.6 million seats and berths daily. Complex rules, validations and fare-computation techniques are interwoven in the application" [3]

Now, one can absolutely argue about whether this form of rate limiting is the right approach, but to circumvent something that is clearly prohibited & charge money to do that is illegal.
This does not mean that I think the current system is perfect OR that there aren't other players who also have backdoors into the process; just that the action is not as egregious as 'BUREAUCRATS STIFILING INNOVATION'. There is more nuance needed here [1].
"According to the sources, the apps enabled users to book Tatkal tickets bypassing security checks on the IRCTC portal. His mobile applications were unauthorized and had features to bypasses Completely Automated Public Turing Test (CAPTCHA), a security measure that users must fill in while logging in to IRCTC. As per reports the apps also bypassed other security measures installed by the IRCTC." ... "However, railway officials clarified Yuvrajaa bypassed the railway system and made money illegally which is a crime. He wasn’t event an authorized agent registered with IRCTC to book tickets. RPF has registered a case under section 143 (2) of the Railways Act (penalty for unauthorised carrying on of the business of procuring and supplying of railway tickets).
Developing an unauthorised software bypassing e-ticketing system is an offence. Such applications defeated the purpose of having a first-come-first-serve system and benefit only a few who use the software."
This govt., like most Indian govts, has a stupidly archaic & top-down / low-trust / risk-averse / bean-counter approach to innovation and transparency (case in point, the Covid tracking app Arogya Setu's sordid development & transparency issues), but this specific incident isn't the right stick, IMO. :)

Going out further afield, exploring forms of intelligence & cognition that are very different from humans, Peter Watt's blindsight (firefall) series is an idea-filled, dense, very satisfying read. [2]

For PC-based training sims, we'll probably get the HTC Vive. And the Pico for the quest equivalent.
Re reservatol, the jury is really out on that one too. [3,4]
