While it is owned by Norway's state oil company, it supplies the UK National Grid and receives UK government subsidies.

Those aren't the costs of generating the energy. They receive ~£140/MWh in government subsidies, and ~£49/MWh for wholesale supply.

Well, it shows that Google can develop a new transport layer protocol over UDP.

lumisota | 8 years ago | on: Lying to TCP makes it a best-effort streaming protocol
Your point about resegmentation (in combination with loss or out-of-order delivery) is why a framing layer, like the one in Minion, is necessary. The Minion paper [3] does a good job of illustrating the problem.
lumisota | 8 years ago | on: Lying to TCP makes it a best-effort streaming protocol
Indeed. Though that issue sort of validated the approach: middlebox vendors will latch on to any unencrypted bits they can. The only way to stop that is to encrypt _everything_.
lumisota | 8 years ago | on: Lying to TCP makes it a best-effort streaming protocol
QUIC demonstrates a better approach: encrypt everything, limiting the ability for middleboxes to make assumptions about behaviour.
lumisota | 8 years ago | on: Lying to TCP makes it a best-effort streaming protocol
It’s been shown that leaving holes in the sequence space isn’t good for middleboxes [0]. Wanting TCP to behave more like UDP is a reasonable goal (e.g., for reachability), but you throw the benefits away if 20% of connections are disrupted by middleboxes. Other approaches, like Minion [1] or TCP Hollywood [2], see deployability because they adhere to the assumptions made about TCP by middleboxes.

No prices on the shelf in this article: https://www.recode.net/2017/5/24/15683852/amazon-books-nyc-t...
Maybe it depends on the state, and its laws on price marking.

Apple's signing the updates anyway; HTTP will be much more performant.

This is how Amazon Books stores work. Prices aren't displayed on the shelf, but using an app. The price is different for Prime members vs. non-Prime members.

A Prime subscription isn't required to use the store.

Isn't it up to the bank to allocate its resources responsibly?
lumisota | 8 years ago | on: Now that the FCC has repealed net neutrality, let’s adopt it in California
Sorry; I (and presumably your original comment) meant the designation of Internet service providers as common carriers under Title II. This designation was applied in 2015.
lumisota | 8 years ago | on: Now that the FCC has repealed net neutrality, let’s adopt it in California
Title II was only introduced as a result of the Open Internet Order (from 2010) being overturned. Net neutrality principles have been sanctioned by the FCC since 2005; removing title II designation and moving away from these principles is a shift that should not be understated.
