But the underlying principal is the same. You require participants to spend X time in a problem with no shortcuts. Changing the problem does not allow you to bypass this issue. If you choose a problem that requires less time to calculate, you increase the probability that someone spams the network with fake data.

You either have a centralized system that can cheaply tell you if something is legitimate, otherwise this is the only way to protect a decentralized system. To my knowledge, there is no altcoin with any significant amount of use that does not use this principal. Please tell me which altcoins do not use this principal.

Customers don't care how long a transaction takes for the merchant.

Have you ever tried selling anything for bitcoin? Nearly no one will use it even when being told of all the "benefits". They don't want to wait 30+ minutes. When they see they need to give some exchange a scan of their passport and wait 3-5 days to link their bank account, and losing the ability to do a chargeback, they never think about using Bitcoin again.

If it becomes worth it to break bitcoin, these vulnerabilities will be used, discovered faster, and likely won't be published before someone uses it to profit off Bitcoin and crashing the price.

Bitcoin is priced this high because uneducated people expect it to replace paypal and credit cards but it will never be able to because 1 transaction take 30+ minutes and that is by design. The faster they make transactions take, the higher chance of forgery. Other crypto-currencies that attempt to have faster transactions are simply trading safety for speed.

Ok and how will you pay the guy who owns the lumber if you have nothing he wants? And the guy who owns the construction bots? And the owner of the land?

And I can spend money I get from Paypal as soon as I get it. I don't have to wait 1 hour.

As someone that has actually tried to sell things with bitcoin, there are major flaws with it, and they will never be fixed because these problems are inherent to blockchains. And people trying to get rich quick keep spamming forums and HN with blockchain technology X Y Z without acknowledging these problems.

1. It is really annoying to buy. You need to go out of your way to link your bank account and passport/driver's license at any major exchange, and this takes days or even weeks. You cannot buy it instantly with a credit card or paypal unless you find a shady seller with bad rates. No one wants to sell bitcoin for something that could be chargebacked.

2. No chargebacks. Good for sellers but not for buyers. People might be able to live with this if it weren't for the other 2 major problems.

3. Payment takes forever. Waiting for the recommended amount of confirms will take at least an hour?

These problems are deal-breaking and can never be fixed when using blockchain technology.

Routers handle bgp updates much faster. Anycast routing is much more superior to geolocation which gives a completely incorrect location as high as 10% of the time. Anycast ips are also the best way to handle DDoS attacks. Attackers can easily shut down ips listed in DNS while people's ISP and browser repeatedly try to access the same dead IP for hours.

If DNS was an acceptable option, I would have gone with that instead of paying a CDN for an anycast solution.

These are all from my personal observations, they are not something I just heard from "ISP/networking people".

Certainly too expensive for a small deployment which is why people buy from CDNs instead of setting up their own.

If it was as easy as just doing dns geolocation (which is awful due to geolocation failing and ISP caching), few people would bother buying from CDNs.

I'm really suprised they didn't look at all the stories of people before trying to start image or video hosts on Cloudflare and getting booted, as if all the other image hosts were too stupid to use Cloudflare for $200/month instead of paying CDNs tens of thousands a month.

Now with type inference and intelligent autocomplete, these features add back efficiency to the point of making them as fast, if not faster to develop non-enterprise sized programs.

Usually they are so good at their subject that they tend to skip steps in their explanations and forget how difficult a certain concept is and expect everyone to breeze through it.

Unfortunately, universities optimize for research rather than teaching.

> I posted it on Reddit, Digg, and a couple forums that I frequent at the same time.

Imgur was never a reddit exclusive thing. It was just mentioned to advertise and gain loyalty from reddit users.

Hardly for "any programming language".

Cloudflare is not an official government entity. As a business you have the right to refuse service to anyone. Refusing these websites service is not the same as being thrown in jail.

The link in question.

You think they are going to amplify on servers they own?

Dozens of ddos for sale websites being advertised on hackforums being protected by Cloudflare.

1) offline mode

You can't search the code inside a repository, and the back and forward buttons on the browser don't even work correctly. Can't view a single file history either and it is probably missing a lot more.

otherwise why would people bother stating the "or your money back" part?

I don't know how many times I tried to run a php web app just to find out a random php5-* extension was missing, and then having to guess which one.

And young is when you are in your early teens, I think he was a junior in college when this happened and his frontal cortex should have been fully developed by then.
