The Wodge: can London's tallest new skyscraper survive the Covid era?
I'm quite fascinated about how an idea like this gets as far as somebody founding a company when, as several people here (as well as the linked videos) have argued quite convincingly, it appears to be easily debunked.

Are the founders knowingly trying to scam investors? Are they just naive/stupid?

Or am I (and the debunkers) being too negative, and this is just the first iteration of an idea that could one day change the world?

What's really going on?
We already have that in the form of LiFePO4 batteries. They last over 2000+ cycles, use no rare/expensive/conflict minerals and are safe. Also just recently they crossed the $100/kWh barrier in some markets:

https://about.bnef.com/blog/battery-pack-prices-cited-below-...

An ISO container(40ft) of those can store 10-15MWh.

For the cost of the Astravets Nuclear Power Plant in Belarus ($11bln, 2GW) you could have 80GWh worth of batteries - that's a week of backup power for one million households in the EU.

One disadvantage of them has always been their performance in terms of power and energy density, but given that they're currently installed in Chinese-made Teslas, I guess it's more or less a solved problem.
Thousands of tons is a very small amount of mass for gravitational energy storage. The capacity of small pump storage reservoirs is measured in millions of tons. Also one probably wouldn't want to use a somewhat toxic and slightly radioactive material at large scale.
The author makes the claim that these constraints lead to more creativity and perhaps focus. I mean we both probably wouldn't be here if we knew we only had one hour of battery power for the day.

I have never met a modern or progressive thinker who would condemn someone's lifestyle choice: I have only ever heard that as a criticism levelled by reactionaries who have only been exposed to an echo chamber. It is those people who seem to be most unhappy with the choices of others.
But these apps are explicitly designed to be decentralised and avoid state control! I'm no fan of e.g. the capitol rioters, but the analogy with IBM and the Nazis seems to get things backwards. The rioters don't control the government apparatus, they are trying to subvert it. And the use of this technology is to aid that by preventing centralised censorship and snooping.

If you really want to power past Godwin's law, then you could compare them to Hitler in the 1920s, subverting the Weimar constitution.

Not a too original counterargument, but: whenever anyone starts creating more money that you hold, the value of what you have gets smaller.
It sounds weirder than it actually is:

from: https://en.wikipedia.org/wiki/Amiga_4000
The three ISA slots can be activated by use of a bridgeboard, which connects the Zorro and ISA buses. Such bridgeboards typically feature on-board IBM-PC-compatible hardware, including Intel 80286, 80386, or 80486 microprocessors allowing emulation of an entire IBM-PC system in hardware.

from: https://en.wikipedia.org/wiki/Motorola_68040
The 68040 offered the same features as the Intel 80486, but on a clock-for-clock basis could significantly outperform the Intel chip in integer and floating point instructions. However, the 80486 had the ability to be clocked significantly faster without suffering from overheating problems.

Haskell functions are pure, which means they can only access/use what is in their parameters, so unless you pass in some extra context (typically using a monad or an effect), you do not have access to the "outside world".
Yes, they have opt-in e2e secret chats.

Has anyone had a look or knows of production systems made with a Haskell-like language named Curry? (https://curry-lang.org/)

Sounds a lot like Haskell with Prolog...

“ Curry is a declarative multi-paradigm programming language which combines in a seamless way features from functional programming (nested expressions, higher-order functions, strong typing, lazy evaluation) and logic programming (non-determinism, built-in search, free variables, partial data structures). Compared to the single programming paradigms, Curry provides additional features, like optimal evaluation for logic-oriented computations and flexible, non-deterministic pattern matching with user-defined functions.”
Vintage cars might still have much of the same appeal because they have tended to become increasingly more complicated. Perhaps a stronger example would be antique books or furniture.
It works for the moment, but regardless of how you feel about the ethical debate here, the reality is that censorship resistant platforms will emerge to cater to the growing population of deplatformed/censored/banned/cancelled content creators and participants.

Whatever form that innovation takes, I wonder if it will ultimately be the new standard and we'll all ultimately be on it and be facing the same problem again.

I am not shilling for Telegram. I have no reason to. I can switch to Signal with my most important contacts in the space of one hour if I wanted to. I never invested any money in them either. I won't get sad if they get nuked from orbit tomorrow.

But it's really baffling how non-constructive most Telegram HN coverage is, both articles and comments. Sure, they have no bulletproof end-to-end encryption of messages. So, like 99.9% of all apps on all app stores then? Some generic marketing on the homepage using vaguely non-accurate language ("secure chats")? So, again, like 99.9% of the apps that have a page and put marketing lingo on them?

What's so uniquely awful about Telegram?

It's legitimately intriguing how hostile HN gets at the mention of Telegram. There might be some interesting sociological study hidden there somewhere.
Probably the bars are square and thus act like corner reflectors (retroreflectors), giving a very bright radar return similar in intensity and position to the right angle at the base of a wall.
AWS isn't like a supermarket. Depending on the context it's better analogised to something like a car rental chain or a large shopping centre. They're providing ongoing, rented, commodity infrastructure that is subject to acceptable use policies.
> USB-3.X cables features 8 wires.

Nope... it's even more complicated. Up to "3.2 Gen 2x1" they have 8 wires, but "3.2 Gen2x2" has 12 wires. There's two pairs of RX and TX each, i.e. RX1- RX1+ RX2- RX2+ TX1- TX1+ TX2- TX2+ D- D+ PWR GND = 12.

And... that's still not correct: USB-C to USB-C cables have an additional CC line which carries the Type-C extra negotiation (e.g. alt mode switch, power levels.)

And just to fuck users over even more, there is a difference between a 13-pin full-function "USB 3.2 Gen2x2" cable and a 13-pin full-function Thunderbolt cable: the Thunderbolt cable reports an extra "vendor descriptor" on the Type-C negotiation channel, indicating support for TB. The cables are otherwise physically identical, but these extra bits come with a ~$15 markdown.

(Oh and the PWR/GND lines can be 3A or 5A, but at this point...)

The article is, however, correct in its conclusion: a "Thunderbolt" cable will always work for all USB standards. The only free variable on a TB cable is whether it does 3A or 5A for power.
Not scorned, just a little bored of being told by advocates how the cloud will do wonders for my businesses or my clients and then seeing the end results not live up to the hype.

I'm not saying there are no benefits to cloud deployment. It does have some clear advantages, and I've repeatedly cited the rapid deployment of the hardware and connectivity in this very discussion, for example. It hasn't come up much so far in the parts of the discussion I've been in, but I would never claim there is no-one with a good use for the more niche services among the hundreds available from the likes of AWS, either.

However, I mostly operate in the world of smaller businesses, and in this world simplicity is king when it comes to infrastructure. We are interested in deploying our software so people can run it, whether that's for a client's internal use or something that's running online and publicly accessible. Setting up a new server is mostly a case of installing the required OS and hosting tools, and then our software will take over (and that work would be essentially the same wherever it is hosted), once you have the hardware itself installed and connected. Configuring a new office network is something you'd probably do in a day, again once the physical aspects have been completed. You slightly mangled the timescales I actually suggested in your quote, BTW.

These systems are often maintained by a small number of team members who have the relevant knowledge as a sideline to their day jobs. And this approach has been working for decades, and continues to work fine today. Perhaps I have just never met the bogeyman where the operational requirements to maintain the IT infrastructure for a small business (say up to 50 people) are somehow unmanageable by normal people with readily available skills in a reasonable amount of time, so the arguments about somehow radically improving efficiency by outsourcing those aspects to cloud services have never resonated much with me. It's a big world, and of course YMMV.

I’m amazed so many modern smartphones don’t automatically scrub personally-identifying information from EXIF data, especially when posting an image via app or web form. This is not a new problem; the staff at 4chan added EXIF scrubbing circa 2014. Your average website can’t be trusted to get this right, so phone OS developers should save users from themselves.
If they haven’t tried taking over the government yet, I’d say, wait.
Would a better design not to bore downwards instead of build upwards? This seems like such an over-engineered concept that could be simplified and compartmentalised drastically.

There's a whole host of negatives I see in this implementation, not to mention the downsides of erecting a crane-line structure and public opinion.

Clearly you haven't had the pleasure of completing any production grade projects using 'Xilinx Vivado', or for an even richer experience they're repackaged Eclipse 'Xilinx SDK'.

I really hope yosys matures and is adopted in large numbers in industry, to become a de-facto gcc equivalent for FPGA compilation. Decoupling FPGA designs from the half-baked tools that vendors push out would be real progress.

I can't even get Amazon to deliver/resend/refund items that never got to me grumble. I've had multiple orders lost for a month plus now and they're like "blah blah covid, please wait".

Or then I accepted an invite to Halo Band and it died on me 2 and a half months in, just stopped charging... not only did the support agent tell me to try using my phone charger (the Halo uses a proprietary connector...) to charge it, he then insisted I needed to buy a replacement power adapter and try that before they'd do anything. For a beta product that was (is?) invite only. Eventually I got Amazon to send me a new device, which came in a plastic baggy wit no bubble wrap dropped into one of their soft mailers with a refurb sticker on it...

I'm going to need them to get all of their departments on the same page.
> What's so uniquely awful about Telegram?

Telegram puts its users in danger by lying to them. They claim to be a secure, encrypted messenger but do not actually encrypt chats.

Then there’s the backdoor...

I'm a hard no on this. I work in education, where everything went from in-person to online in the course of a few weeks and everyone (expectedly) hated it. synchronous online destroyed the previous advantage of online (asynchronous) and hasn't found a way to provide any benefit over synchronous in-person.

there is a clear opportunity for better video experience online but I expect that 2021 will be the year that everyone runs screaming for the classroom and office.

I never share my location with anyone other than by telling them in normal language than I am at some specific location ("the ferry terminal at Marstrand" or something like that). I don't give the few apps I still use - I try to use self-hosted web services where possible - access to location data, other than those which need it to function (OsmAnd~ etc.). To use some WWII-related terms, "Feind hört mitt" (seen om german-language equipment, it means "the enemy is listening in"), "En svensk tiger" (a Swede stays silent (so that the enemy can't listen in)) or, more tangentially related "loose lips sink ships".
I am aware of that, which is why I expressly stated a related condition of restoring those person's rights as citizens by linking the temporary suspension of those rights to continued education (remediation of the citizen being failed by the state).

Nothing to do with the CPU or components - it's simply due to the lack of WAN connectivity.

Old computers contained firmware by the way - BASIC and the OS weren't loaded from disk, they were stored on internal ROM.

The only reason built-in functionality didn't change, was again just due to the lack of WAN connectivity. You can achieve the same level of privacy today by just not connecting to the internet and using your machine offline only.

If the fork is closer to the final result that most people want, it's a no-brainer that developers, maintainers and the community will follow. There's no incentive to stay behind.

It's worth studying the case of OpenOffice.org and MySQL. Both of these weren't satisfactory to the community for <reasons>, so the community forked them and did all the high-demand feature implementation on the fork. Now the original projects that were forked from are near-ghost towns.

Thanks for sharing, but honestly, what does your comment add to a discussion of the post, which is about what works for them? You're making a rude comment that assumes they don't already know these things. Have you considered the possibility that the tiny slice of the world you've experienced is just that?
Yes, TB (both 3 & 4) cables always have all USB features. They can still be 3A or 5A for power delivery though.

As far as hubs are concerned... they're designed for TB uplinks; AFAIK most silicon that exists can fall back to USB3 with significantly reduced functionality but you're gambling again at that point. I'd recommend against it.
ML and NLP surveys are outdated basically the minute the author hits send nowadays. With GPT-3 all of these old school NLG companies seem quaint. Much of their functionality can be replicated in minutes with GPT-3, even by non-technical users familiar with prompt design. As soon as OpenAI offer fine tuning OOTB (coming soon) NLP/G will be all but solved for 99% of use cases.

Trying to engage with the MAGA crowd has been an exercise in futility. Despite no evidence of election fraud on the scale that would overturn the result and every institution in the country asserting the election was free and fair, they refuse to accept it. When they do not act in good faith, incite violence and commit terrorist activity - I think these actions, which were the last resort, is the only sane thing to do.

Can we get some better sources? This seems like an awful lot of hearsay, and there have been several comments from HN readers in this thread[0] and another[1] indicating that there is no public evidence to support these claims. Given that the author is alleging this is a crowdsourced effort, such evidence should be trivial to locate, but none has surfaced.

Audio carries 80% of the intellectual content of most telepresence. That's why when there's a live cross on TV News and the video works but the audio is missing, they give up and return to the studio until the audio is up.
eludes -> alludes
That's ridiculous circular logic. The story is valid because it's not being covered? Millions of stories are not covered by the news every day. A functionally infinite number of non-stories are not covered by the news every day. The non-coverage of a story has no bearing on its validity.

Your claim is also invalid on its face—the election theft narrative is being spoken about endlessly. Trump's claims are headline news every single day. A significant fraction of the population believe it. So to claim that the story is being "censored" is simply wrong on the facts.
That is impossible with almost all non-trivial software. Testing proves only the presence of errors not their absence.
Well, sue them. I don't think all other messengers save for maybe Matrix and Signal are any better.

Even better, make a messenger that does encrypt chats. Make it paid. Prove its end-to-end encryption properties. I'll buy it and advocate for it to my friends and family.

In any case, the constant hate is (a) very tiring and (b) very uncharacteristic for HN.
Pre-Google Reader, nearly all RSS readers were desktop apps with no synchronisation. Then Google Reader launched, was free, fast, available anywhere, was always up to date with how far you’d read, and came from a reputable household name.

After Google Reader launched, other companies built basically the same thing, and some of them flourished after Google Reader was shut down. But none of them have met all of the above points.
I think a step between what we have now and full human replacement will be roads that are certified for fully automated driving. Those roads would avoid features that confuse the automation, or have some sort of passive or active assistance installed.

There are already places that regularly confuse human drivers, and those do get fixed (though usually only after someone dies). I don't see why we couldn't do the same for driving robots, especially when they get more common over time.
