I don't see why the escapee needed to register a domain similar to that used by the officialdom. Nowhere in the article is it implied that the escapee needed to be able to receive email at the correct address. Even if that were the case, adding a Reply-To would probably have sufficed.

I'd say registering a domain and setting up email is at least as difficult as setting the "From" field :).

The "my3" account management interface on three mobile appears to have suffered from a +The Daily WTF moment...

My God, I love PostgreSQL. It was a long road to this opinion, beset on all sides by distractions such as SQLite, MySQL and NoSQL but I've seen the light. It Just Bloody Works.

Welcome to the love I discovered in 1999 :)

As usual, this is more flattery than divination but it contained the lovely "tell":
> Giggles when someone says the phrase "This is recorded on sticky-tape and rust"
Indeed, I did giggle when I saw that but I seriously doubt that anyone a) under the age of 30 or b) who didn't grow up watching UK TV would get that.

A few Masters student projects ago, we had someone in the lab experimenting with "sudoku codes" where one transmitted information in the form of unsolved sudokus with more digits given than necessary but with some of them possibly corrupted. I wondered at the time what the theoretical entropy of a solved soduku is. According to this page, there are 6,670,903,752,021,072,936,960 solutions or, approximately, 72 bits. An individual digit in a sudoku grid encodes about 9-and-a-half bits (1 of 9 digits in one square in a 9x9 grid) so, in an information theoretic sense, you should always need at least 8 filled in digits for the sudoku to be soluble.

You need at least 17 for it to be uniquely soluable.

I'm doing a big staff survey which has been sent around to members of staff. The following question popped up as the first question in a section with no context and with no definition of which "communications" from whom about what. Oh, the irony...

Strongly Agree to Strongly Disagree. Oh for a "not applicable"(!)

A 1972 preview of the technical wonder which was a TV camera which could be lifted by one person. Think of this next time one complains that the two cameras in your pocket do not have sufficient megapixelage.

The caught my eye in light of my declaration of love for PostgreSQL yesterday. The top reddit comment is unusually mirthful: "99% of projects would be better off with a relational database. [...] People are excited about mongo because "it's javascript!". These people are morons."

It's probably a little strong to say that (and MongoDB has more than a little C-ish in its implementation) but it is certainly true that its easy to start using MongoDB without fully grokking where it is appropriate.

If you're interested in the origin of "this is recorded on sticky-tape and rust" from my previous post, see 8:57 in this video. The Secret Life of Machines with +tim hunkin is among some of the best television made IMHO :).

Part three of my home-built 6502 based computer series. In this episode we have an OS! It has a command line and can run programs uploaded via XMODEM and everything.

2MHz if it's the one I think you're talking about. (I.e. the processor crystal and not the VIA. The numbering of components varies a little over time in my schematics.) It's actually a self-contained oscillator; put 5V across it and a clean 2MHz clock comes out.

In principle my system could go higher in clock speed but I'm aiming for BBC Model B-era computing as a broad goal.

I found a few moments last night to properly eradicate polymer.js from my personal website and slim the theme a little. I've gone back to bootstrap. Material design and polymer may be great for single-page apps on Chrome but a small personal site is better off moving a little back from the bleeding edge.

The Alexandra Arms in Cambridge has managed to source the rare vegetarian venison for their burgers.

Affordable. Silly. Decent. Reasonably priced beer, cheesy music and a good place for a post dinner drink and chat.
