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 Russian translation of this article can be found here, contributed by Timur Demin.
• 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.

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

enum { BMAX = 32, BMIN = BMAX / 2, BHEIGHT = 6 };

struct BNode {
    uint32_t length;
    Key keys[BMAX];
    union {
        BNode *children[BMAX];
        Value values[BMAX];
    };
};

ServiceWorker for github pages

This is a ServiceWorker template to turn small github pages into offline ready app.

Why ?

Whenever I make small tools & toys, I create github repo and make a demo page using github pages (like this one).
Often these "apps" are just an index.html file with all the nessesary CSS and JavaScript in it (or maybe 2-3 html/css/js files). I wanted to cache these files so that I can access my tools offline as well.

Notes

Make sure your github pages have HTTPS enforced, you can check Settings > GitHub Pages > Enforce HTTPS of your repository.
