You're absolutely right! The biggest things I learnt from that were:

- overprovision resources for big demos by a significant amount

- test your demo before you give it

- deploying pets (servers you ssh into and lovingly configure) instead of cattle (instance abc123 that's created automatically) means you can't scale them as easily

- if you have concerns about a big demo, particularly ones that could be fixed by spending $10 on EC2 instances, you should fix them yourself instead of emailing the tech lead and assuming he'll handle it

- spinning up processes with phusion passenger is awful[0] and we should have been using something threaded like puma

That being said, the same footguns apply at various points as you scale, because Ruby's GVL still exists, and because even though threads are lighter weight than processes, they're still relatively expensive to switch between and to maintain in memory compared to e.g. Go/Elixir lightweight threads or evented IO.

Unfortunately (or perhaps fortunately) the problems with threaded IO start applying well above 20 concurrent users, so I don't have any fun stories about failed demos involving Puma instead of Passenger.

[0] Specifically, Rails processes take up a lot of memory, none of it is shared, context switching between processes is pretty expensive, and so you're limited to a smaller number of processes that can become IO-bound very easily
Incorrect.
The proof of work difficulty scales automatically. If the miners/hash-power reduces then blocks become easier to mine.

The Bitcoin blockchain could subsist on a minuscule fraction of todays energy usage if the majority of miners decided to throw away their investments and stop mining.
For context... I don't think Gentoo has statistics for the relative number of users on each architecture, but Debian does (at https://popcon.debian.org/, scroll down to "Statistics per Debian architectures").

Relative to 185,729 samples from users on amd64, there are:

5 users on alpha
8 users on hppa
5 users on ia64
5 users on m68k
7 users on s390x

This is a vanishingly small number of users we are talking about here. Most of these architectures have been out of production for the last 10-15 years; they're largely only used by retrocomputing enthusiasts, not as production systems.
The command to show dotfiles is the two most commonly used modifier keys, plus a dot. If you told someone the shortcut was mnemonic but didn't tell them the specific keystrokes, they'd probably be able to guess with a minute or so of experimentation.

Replying because of this - are you using libinput instead of the synaptics driver? Libinput is really a very big downgrade, and hardly has any configurability. I would be very surprised if you were unable to tweak Synaptics to meet your needs. I find my touchpad far smoother and easier to work with than any Apple touchpad I've ever tried.

For reference, here are the settings for pointer motion alone that are exposed with the Synaptics driver in KDE. https://i.imgur.com/W0dDs2j.png

It looks that way to me too.

I converted the conversion rates from unique-trial-paid for each scenario. It looks like 0.846% for credit card required upfront and 0.264% for no credit card required. So *net conversion is ~3.2x higher when a credit card __is__ required upfront.*

Showing my work:

I eyeballed each bar chart and turned it into a data table. I'm getting median unique-to-trial conversion rates of 3.1% (credit card required) and 6.1% (credit card not required). I'm then adjusting these to account for the % of "don't know" responses. So, adjusted medians of 1.8% (cc required) and 3.3% (cc not required).

Following the same process for trial-to-paid yields medians of 47% (cc required) and 8% (cc not required).

Multiplying each pair yields 0.846% (cc required) and 0.264% (cc not required) unique-to-trial-to-paid.

that would be a bad idea since the tiles are ever changing. the master copy of the data is in a vector format. the idea is you want to run the (free) software engine that turns the vector data into various zoom levels of raster tiles, on demand. the vector data is really quite small, an entire large-population US state with many complex cities is under a few hundred megabytes.

In Firefox, by default, you can search for text of an element using forward slash. Then you hit escape and hit enter to activate it, or tab to navigate past it. That alone made 90% of websites practically mouseless for me
I should have added: regulate them to increase competition. When the long distance telephone market was deregulated in the 1990s, ending the monopoly of the Bell Operating Companies, prices crashed rapidly and service quality improved - albeit for a time.

Similarly, when you “don’t have a choice” except to work with, say, Google, there is no incentive for them to provide good service. Find a way to introduce competition and everything magically transforms.
I love new languages, and I love that you have all the basic elements of webapps as first class citizens.

....and then I saw that the page is still written using React and db access uses Prisma. They are not dependencies, you have to now about them, and their syntax and how they work.

What is the incentive for me as a developer to learn both them and wasp? Especially since there are multiple places where the wasp layer is a thin layer over the underlying capability supported by those dependencies.

Dont get me wrong. I say go bigger and make it a full-fledged DSL that generates react and prisma code without making them __visible at all__. That way nobody has to learn anything but wasp. Sure, you will be limited by whatever your underlying implementation layer is, but you can now switch from them easier, and its likely to last longer (there __was__ a time before React, and like will be one after too).

Can you be the +1 layer that people dont have to look under? More specifically:

1. Can you have inline .js files? Even better: Can you bring the page content _into_ wasp's syntax? It currently says a webapp has pages and routes, how about expanding to say a webapp has components, elements and text?

2. Same question for storage schemas and migrations. Would that help with NoSQL integrations (vs expecting Prisma to support them)?

3. Can you eliminate the "Note:" sections in https://wasp-lang.dev/docs/language/basic-elements? Those are the leaks in the abstraction called wasp. And if the answer is no, then should there be a better abstraction?
Linode, DigitalOcean, or a $200 used server from EBay. Both Linode and DO also have really good Kubernetes services. AWS and alike force users to stick to their ecosystem of products, and come with all sorts of weird pricing models. And if you really need some sort of serverless features or BaaS, you can just self-host that on a VPS.
If I was going to go mouseless, it would be to just use a touch screen. But then I'm much more keen on front end stuff. It would have to find a way to decrease the amount of inputted text right down though.
> If someone posts something in your forum. Can you legally repost in twitter saying.. so and so just posted?

It may constitute fair use. Publishing their work in a book and profiting from it is another story.

> When you post in a public forum do you automatically assign the copyright as public domain by virtue of where you posted and who can see it?

No.

> Facebook owns all of the content you post (pictures/posts/videos).

As the sibling says, they do not.

> Doesn't this apply to all/most sites with user generated content?

No. A given website may state that as a condition of its use, users must assign copyright to anything they post to the owners of the company. This is not a common condition.
The part that impressed me:

"The amount of electricity consumed every year by always-on but inactive home devices in the USA alone could power Bitcoin for 1.8 years"

In other words idle devices in US could power all of Saudi and Netherlands. And all it would take to reduce that is some proper thoughfull design.

You are not the customer. You do not buy the SCADA system.

You are the consumer. You want pure water. That I believe. The people buying the SCADA system want to be able to look at a dashboard while staying at home in their slippers during COVID-19. Worse yet, the SCADA system might have already been bought some time ago -- as is very common -- and adding "Hey I want to look at this from home!" might have happened a decade after the purchase.

All of this is based on the premise that

1) Countries want external control of their international transactions

2) They accept Bitcoin as said thing.

They are sort of , to some degree, forced to 1, by the US Govt. there is likely near zero chance they WANT this as a property though.

2) This is also not very likely. With some 70% of BTC being mined inside of PRC and a 51% attack possible, there is a lot of trust required of the Chinese govt. Unless this changes, I don't see countries wanting this to happen, either.

So while what you say is theoretically possible, I don't think it's very likely. I think what will happen, and what already is happening to some degree, is countries are just deciding to convert in direct currency transactions and not use USD as the base contract amounts, because the US reserve currency status is slowly declining. I.e. they are using the dominant currency in their region ( Yuan/Yen, Euro, USD, etc)

It's unknown how the US will respond at this point, with Trump in office they were basically ignoring the problem(that I'm aware of). How Biden's team will handle this is still unknown(or if they also will kick the can down the road).

We do see some corporations using BTC as a store of "cash", TSLA the latest big company to do so. It's still unknown if this is just a short-term thing to make some extra dollars on otherwise boring cash, or if this will be a long-term situation.
To be fair the difference in bitrate between 1080/4k is probably (in my opinion) a bigger difference than the pixel count, uncompressed 1080 looks pretty damn good.

The sibling comment to mine interpreted you correctly and I apologize for misunderstanding your intent.

For what it’s worth where I was going was all as explicit as I could make it, and based on a perception that you were reacting negatively to an article openly discussing a sex work publication.

Sorry again, and I appreciate your productive clarification.
Edit: A warm mention of Steven Black's hosts, https://github.com/StevenBlack/hosts for those interested in more of OP's subject.

Use both methods instead of just one. They differ in nature, and can be implemented at different perimeters of your network. Maybe there exists certain chokeholds in the network where multiple devices can be protected in one go?

Personally, I would have pure IP blackhole routing performed in the router providing WAN access to internal networks. A blanket protection for all desktops and 802.11 devices inside.

Many devices today are locked-down and editing hosts records can be untrivial. Instead of relying on 0.0.0.0 routing through hosts, the same effect can be obtained by setting up a personal DNS server e.g. bind9 with RPZ's listing the targeted domains[1].

Why all that hassle? Because an unrooted smartphone with a Wireguard link to the DNS server (or full-on VPN using that DNS server), can have lookups made through the server you control. And that DNS service is available to use on any local network/Wi-Fi one has to use. IIRC 3G/4G/5G WAN routes were harder to get right, but I think it was possible. One could always route all traffic through a purposeful VPN.

Defense in depth.

Please provide your detailed analysis of the cost of operating any maintaining software at scale to back up your arguments. Please site sources and make sure your data comes from enterprises at the same scale as Apple. You comment is a rant with no data.

I have run product teams as well as run production customer facing networks. It is never as simple as your comment says. While I can GUESS on 20+ years of experience in the space that Apple is likely making a nice profit on their cut, I in no way believe it “free”.

Also please tell me why a company is not allowed to profit on their work? Where is the bill to open the Google Play store, or the Samsung store, or the XYZ store for your TV apps?

I personally am very happy with the knowledge that in general the Apple Store is safe for my non-techie wife and kids. I cannot say the same thing for Google that my in-laws use, having been forced to remove the spam apps the Google store happily allowed them to install. Reviewing an application is not a 100% software / script driven function. Apple seems to set the bar on quality and trust for that. I am happy to pay to live in that system.

This is being driven by someone that is pissed at Apple because they could not deal with the terms required to provide an application in the Apple ecosystem.

It’s a variety of factors. Lower TTLs are normal and respected by DNS servers. Caching is invalidated more intelligently. There are fewer mismanaged DNS implementations on local networks. Generally, computing has outpaced the demands of DNS.
I don’t understand this at all. No matter what happens, my hands are mostly on the keyboard.

Plus the mouse can only point at or navigate to things on or adjacent to the screen. If I want to navigate to a symbol not on screen or run an arbitrary command then resume typing, I don’t see how the mouse helps me go faster.

If you think BTC is anonymous you have a mistaken understanding of how permanently public blockchain transactions are.

A given transaction might be "anonymous" today(for some definition of anonymous), but chances are it won't be anonymous at some point in the future. This may or may not matter given your definition of anonymous, but to think your transaction will STAY anonymous forever is just asking for trouble.
