Replicating the experience of in-person communication much more closely than video and 2D displays will ever do. That's a noble research goal if nothing else, I don't get the skepticism.

There are several reasons 3D content and previous generation displays didn't take off, but there's no reason to believe a revolutionary new approach and product couldn't change this (e.g. electric cars were invented in the 19th century and are only now becoming popular). AFAICT the real time photogrammetry they're using here along with the no-glasses 3D display is a major leap forward. If they can get it cheap and reliable enough to mass market, it would be a game changer.

I certainly know what kind of display and teleconferencing software I want when the next pandemic hits, and it's not what we have now.
For Doom specifically, which uses a P2P networking model, yes, that probably would have been technically superior. It would have taken more work, though -- this demo was thrown together pretty fast. Durable Objects could still have been used for setup, yes.

Most modern games use a client/server model, in which case the possible role of Durable Objects is a lot clearer.
Doesn't matter. Anything that is not the main goal (in that case, the checkout process) should be isolated and not break it.

Whoa, hello everyone, founder here.

I wasn't sure what would happen if I posted on HN but I just wanted to say thank you to everyone checking Sparel out and signing up, this means a lot to me, especially because I'm not funded, and I'm going at this alone but not really because everyone wants to help. This is just... incredible.

Please keep the feedback coming. I'm also very curious to know what your job title is? I'm trying to dial in the target audience - it's jumped a few times but I think I might be getting closer.

Sparel has been my passion project for the last few months. It started as a Notion doc, then a Miro doc... and then back to Notion, and then a web app. This is driven by my own need to expand how I solve problems. I'm fascinated with the type of problem-solving behind big projects like landing a rover on Mars... I would love to bring the magic that goes behind solving stuff like that to everyone regardless of background in problem-solving. To me, that would be amazing.
I hate this issue.

The answer is "yes", but in practice the question isn't that simple.

The use of a technology by criminals should not necessarily mean the technology needs to be curbed.

Insofar as we know criminals are using it, I'd ask "how" - and can we innovate on the law enforcement side without unnecessarily interfering with the lives of civilians?
Haha yikes. I'm not saying that your idea wouldn't work, but I'm definitely not going to do it. :)
Under the hood, spaces are rooms - and we made the decision to keep using a # sigil to refer to them, given the act of joining and being invited and having multiple aliases etc is the same as a room. When you say “hey, come join #community:matrix.org” does it really matter if the thing you are joining is a room or a set of rooms?

That said, it’s subjective, and we went back and forth on it. My original proposal had a twigil of #+wherever:example.com, which in retrospect was daft. I think it was a member of the community who proposed just using plain # aliases - hard to tell given https://github.com/matrix-org/matrix-doc/pull/1772 is so heavily commented that it crashes if you expand the comments :/
HVEC is no longer king of the hill when it comes to compression efficiency. AV1 and the upcoming VVC do better.

That said, my intuition is they aren't doing a pure video encoding solution. The fact that they talk about 3d modeling leads me to believe they are doing a combination of model + texture to get the realistic results. That would significantly decrease the amount of bandwidth and computational power needed. Over a low bandwidth situation you'd simply need to send model updates and do some smart interpolation to determine what things should look like.

Similar to the concept that playing a 3d game requires MB of resources but recording the same game at 8k would require a boatload more memory.

My assumption is they are using LIDAR to get a good model, high quality cameras to texture things, and a nice AI to stitch things together and interpolate when data isn't arriving fast enough.
Makes sense in theory but that’s not what I see in practice.
Yes, and also yes, it is a meme. Money itself is just a meme, we just don’t all agree to its definition. Bitcoin as a meme is self reinforcing, incentivizing meme, with so many self defense mechanisms — it’s crazy. Highly contagious too! Groundbreaking and game changing in its very existence. What I wonder about constantly “is it the greatest meme”? Bitcoin consumes the lives and speech patterns of its advocates far stronger than any religion. It’s easy from the outside to say “that’s not rational”. Can we ever go back to less?

Argument: money is a meme. Bitcoin could be the strongest meme ever, as demonstrated by its consumption of energy, a proxy for human perceived value. Arguing over energy is just arguing over human preference.

You can’t block access to a peer to peer network unless you block internet access (in which case you can access it via satellite). Blocking Twitter/Github etc access is pretty easy since they are centralized legal entities to which you can issue subpoenas, force the ISPs to block their DNS, raid their servers etc.

Blocking based on traffic analysis is easily bypassed by using a VPN/tor

Isn't that only for Bitcoin Cash?
...you do realize that most of the world's money supply exists in the form of derivatives, right? A single-digit percentage is actual cash. You're committing a strawman. They didn't say anything about how the proportionality of crypto's use breaks down - they simply stated that it has achieved the basic use it set out to. And they're 100% correct - I use crypto to buy things quite regularly (email, VPN, etc), and will continue to. Really, the only thing preventing me from doing so more often is hard-headed people refusing to support it, because it's "mostly speculative."

Show HN: Railway – Deploy Rails to AWS with Ansible
At the start of the year I decided it was time to move my company's app from Heroku to AWS. Main reason was that our clients were on South America, where Heroku does not have a datacenter. At the time I did not find a guide on how to do this, so I had to spend an entire week (~40 hours), learning about AWS and Ansible, and feeling like I was continuously banging my head against a wall. Fast forward a few months, and we have an entire repository of playbooks that can, with a single command, do most of the things that Heroku did for us.

So I decided it might be worth to open source the entire thing, if only to save others some of the frustration I felt. I named the project "Railway"and here's what you get:

1 - Create a custom AMI with everything a Rails app need;
2 - Create a staging environment with webservers, workers, cache and job redis instances, postgres database and support for up to 9 branches of your app at the same time;
3 - Create a production environment with load balanced webservers, workers, cache and job redis instances, postgres database with a read replica;
4 - Deploy to staging;
5 - Deploy to production using rolling restarts;
6 - Update production servers to get the latest security updates;
7 - Upgrade production servers to a new AMI with zero downtime;
8 - Compile ImageMagick and Libvips from source in order to get more up to date versions than what is available in Ubuntu's repositories.

As you can imagine this is not an easy project to use. That’s why I included guides for instaling, running everything for the first time, customizing for your own app and the day to day workflow.

I hope this is useful for people who have considered moving from a PaaS to a IaaS before, but didn’t know where to start.

How big does n need to be before the expected runtime is less than n/2? And at that n, what gate fidelity is necessary to ensure that the answer will usally be correct?

It's getting downvoted because it is repetitive, with thousands of effectively identical copies being posted on HN yearly. It is not insightful. It is not clever. It's not reacting to the story, except for lazy pattern matching. It is just a tired meme that's been flogged all the way down to the bone by now.

(It's probably also not true, when compared to Google's peers. Amazon and Microsoft similarly throw a bunch of stuff on the wall, and unceremoniously kill the failures, but neither their launches nor cancellations get this reaction.)

Oh, Windows 7? That does explain it. Windows TCP stack really improved in 8.1. The main change there is the auto send buffer tuning which allows automatic growing of SNDBUF. Let me see if we can put a dirty hack^W^Wworkaround for Windows < WIN2012R2SERVER that would unconditionally set SO_SNDBUF to something like 1Mb.

>> Within the decade, Google aims to build a useful, error-corrected quantum computer. This will accelerate solutions for some of the world’s most pressing problems, like sustainable energy and reduced emissions to feed the world’s growing population, and unlocking new scientific discoveries, like more helpful AI.

Are "sustainable energy", "reduced emissions to feed the world's growing population" and "unlocking new scientific discoveries like more helpful AI" goals that Google is currently working towards?

Regarding the need to feed "the world's growing population", note that absolute increase in global population per year has levelled off for several decades and may even be decreasing:

If you think that buying into an MLM Ponzi Scheme is a good hedge against inflation, all the power to you.

But in the long run, it's not.

There are no cryptos which effectively server as either currencies or good stores of value. There are always many better alternatives in both cases.

If you want to opt out of currency - that's rational - you can buy land, low-overhead ETFs, indexes, bonds, gold, other currencies, Gold, commodities, and all of the above.

Consider the obvious problem with your stated benefits of crypto: for every supposed benefit, there are already other, better solutions.

The only thing crypto can do, that others cannot, is make you rich, quickly, by doing nothing, by getting others in to the pyramid.

In the long run, crypto has a role, but there's no crypto on the horizon that's really useful. Some day.
Marketing would have made this name up.

I know it’s “fact” but is there any actual proof that demand during/from Covid and new generation of hardware worthy of upgrading to isn’t the actual increased demand for GPUs rather than miners?

I “know” miners are buying cards up and converting energy to heat while many would list climate change as important to them... but is there any proof it’s miners driving the demand?
The brain, right? Without which there is no embarrassment.
The fact that this has 1000+ comments should give pause to anyone thinking crypto is a gimmick
This won't really do anything for availability or reducing scalper pricing. Miners are a sizeable proportion of sales but far from the majority. Gamers will be able to buy more of these GPUs but less of the non-LHR or AMD GPU's. GPU prices won't actually change.

The real reason Nvidia is doing this is that when mining profitability inevitably drops, either because of a crypto price crash or Ethereum moving to Proof of Stake, the miners will flood the used market and ruin Nvidia's profits for a few quarters. Nvidia is trying to get miners to buy mining-only cards, because those can't be sold to gamers down the line. They'd rather mining cards become e-waste in a few years than get resold.

People think Nvidia is doing this to try to help them get better prices now, but really Nvidia is trying to extract more money from gamers in the long term.
This list seems silly. For example:

I think one of the major aspects of this technology is that the person you are talking with appears in its real size, with the same ratio than in real life. Something you cannot do with a smartphone, except if you are referring to a projector.
You can call it dramatic, I call it reality when I make three times in CA what I did in Dallas doing the same job.

The problem is that an engineer, doing the same job, in a state that is wage suppressed can only retire in a state with even lower cost of living. When you have engineers in coastal areas on average making ridiculous sums over their counterparts in other states when nearly all the products are subject to the same taxes and distribution pipeline that begins to sound a bit problematic, don't ya think?

The problem largely lies in reward structure: coastal engineers tend to get a lot more in terms of RSUs but will get similar cash compensation. When you add inflation and home prices (which are savings vehicles) on top it compounds the problem into what we have today. As I said, some is on the state, some is on companies.

The net outcome is that an engineer retires from SF, can move anywhere they want but picks Texas. They buy a house in cash, most likely beating out native Texans and drive the cost of goods up while salaries remain low. They live like kings while the people who actually built up a community and contributed taxes to the state get priced out. This whole paragraph is just paraphrasing state-to-state income inequality though, feel free to read up on it's effects.

> Why would companies artificially push engineers to the areas where they command these disproportionately large salaries?

Because now that this paradigm exists it's rife for exploitation. Companies will pay engineers in Texas without giving them the same RSUs as their coastal counterparts. That's a savings. So sure, they pay people in SF more but they pay everyone else substantially less (beyond cost of living differences). Therein lies the rub.
BTC seems to be about 10 times more volatile than the dollar on a daily basis. Like, last friday, the dollar was down about 0.4% and BTC was up or down 4-5% intraday.

This seems to me kind of like the argument that the government is "just" another gang of armed bandits.

There is a huge amount of value in predictable taxation rather than random robbery. Partly because of the variance, and partly because government has more of a long term interest in the viability of the citizenry, even if it weren't especially democratic per se.

And similarly, there's a huge value in a currency that gradually loses value over time rather than being up or down 5% in a day and 30% in a few weeks.

The whole point of currency is that it's not a long term investment asset, but a tool for trade, isn't it? So why would long run inflation be relevant?

I'd posit that much of the back sliding of social outcomes for western citizens is that their nations now have to compete with places like China that were once 'developing', but are now technologically advanced, and they can also permit factories to use their populations as slaves.

The US and even other countries like Australia, UK, France etc. are willingly voting in governments that dismantle social policies and workers' rights for 'more jobs'. Without protectionist policies, there's no way to reconcile the increased labour costs in western nations, let alone personal liberties. If China is permitted to ascend without improving the rights of its people, that's the country we will have to match.
If one's motivation for using green energy is to make the environment not go to crap as fast, then using green energy to mine crypto doesn't help anything and the use of green energy is nothing but a fig leaf.

If one wants to mine crypto, then do it as cheaply as possible instead. It really doesn't matter what the source of energy is. The entire system of crypto mining is inherently about who can use the energy the cheapest. Whats more, if someone gets energy cheaper it forces others to consume more power too.

If crypto is mined, it really doesn't matter what it uses power it - mining crypto is still increased consumption of power. Someone else is going to have to use non-green energy to do whatever they're going to do.

Could you explain blacklisting? What does this mean? Couldn't there be an API to probe whatever information the developer needs to determine acceleration?
Ed: obviously this does not solve the bigger service of providing "magic" scale up/down, though.

It looks like the "branching schema" is essentially:

CREATE DATABASE branch_name WITH TEMPLATE main;

I might actually have to try this - I hadn't really thought template dbs would be all that useful in pg - but this branch and test för dev use-case is interesting.

Then there's COPY (for data) and rename to "promote" a branch with data (one would probably want to run DDL on main db though:

ALTER DATABASE branch_name RENAME TO main; -- would have to move old main out of the way first - but might be possible in same transaction?
Thanks, I've edited my comment.
That's not the point: the point is that Nvidia want to still have regular customers who, when they think "I need a gaming rig" think "Nvidia".

If Nvidia becomes "GPUs are cryptominers", then once demand dries up, their marketshare is zilch, and no one's writing games optimized for Nvidia cards anymore, and there's a big pile of bugs they've not fixed with new games trying to use Nvidia cards.

Our source-of-truth data store is Postgres, with a Memcached cache on top.

Most of our queries are "pointer chasing" - we follow a reference from one record in memory to fetch another record from the data store. To optimize recursive pointer-chasing queries, we cache the set of visited pointers in Memcached.

We use Elasticsearch for search features like QuickFind.
