• any: magic, ill-behaved type that acts like a combination of never (the proper [bottom type]) and unknown (the proper [top type])
  • Anything except never is assignable to any, and any is assignable to anything at all.
  • Identities: any & AnyTypeExpression = any, any | AnyTypeExpression = any
  • Key TypeScript feature that allows for [gradual typing].
• unknown: proper, well-behaved [top type]
  • Anything at all is assignable to unknown. unknown is only assignable to itself (unknown) and any.
  • Identities: unknown & AnyTypeExpression = AnyTypeExpression, unknown | AnyTypeExpression = unknown

• Prefer over any whenever possible. Anywhere in well-typed code you're tempted to use any, you probably want unknown.

Set up an Upspin server backed by Google Drive

Overview

The purpose of this document is to explain how to deploy an Upspin server on a Debian or Ubuntu based machine - which can be a Raspberry Pi - and, optionally, use Google Drive to back the data.

Effectively, this will give you all the nifty advantages Upspin gives you in terms of file sharing without requiring a costly server.

Algorithm

1. A secret byte you want to read is stored at inaccessible memory location priv_mem.
2. The sender triggers an access exception by attempting to read priv_mem.
3. Due to CPU optimization (out-of-order execution), the load of secret from priv_mem and the use of its value in (4) and (5) below may execute before the exception is triggered.
4. Calculate an offset into a known array probe by multiplying secret by the width of a cache line (or whatever block size the CPU typically fetches, like a 4096-byte page). This guarantees each of those 256 possible offsets will cache separately.
5. Load probe[offset], which causes the CPU to cache exactly one chunk of of our array, populating one cache line.
6. The exception finally triggers, clearing the modified registers...but cached data is not excised.
7. Iterate over all 256 offsets into probe to find out which one loads fast. You've determined the value of secret.
