Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

• A Turkish translation can be found here, contributed by agyild.
• There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

// 🔥 Node 7.6 has async/await! Here is a quick run down on how async/await works

const axios = require('axios'); // promised based requests - like fetch()

function getCoffee() {
  return new Promise(resolve => {
    setTimeout(() => resolve('☕'), 2000); // it takes 2 seconds to make coffee
  });

In general, a cache is a "more local" copy of a memory resource that you want to access.  
Its a copy that is faster to access than the original, but that memory is also more expensive.  

This link, provides some measurements that illustrate the benefits: http://norvig.com/21-days.html#answers

Disk cache is RAM memory, that contains a copy of the information on the disk.  
Typically, when you access something on the drive, the whole page is brought into cache, on the assumption that the next access will be in that page.   
The first disk seek might take 8ms, while seeks from cache 100 ns  (many times faster - note nanoseconds instead of milliseconds)

Memory cache is the same concept, but the cache is located on the CPU chip.  So the original memory access is 100ns, the L1 cache access can be 0.5 ns.
