Word Ladder Solver

This is a repost promoting content originally published elsewhere. See more things Dan's reposted.

It’s likely that the first word ladder puzzles were created by none other than Lewis Carroll (Charles Lutwidge Dodgson), the talented British mathematician, and author of the Alice’s adventures. According to Carroll, he invented them on Christmas Day in 1877.

A word ladder puzzle consists of two end-cap words, and the goal is to derive a series of chain words that change one word to the other. At each stage, adjacent words on the ladder differ by the substitution of just one letter. Each chain word (or rung of the word ladder), also needs to be a valid word. Below is an example of turning TABLE into CROWN (this time, in nine steps):

TABLE → CABLE → CARLE → CARLS → CARPS → CORPS → COOPS → CROPS → CROWS → CROWN

In another example, it take four steps to turn WARM into COLD.

WARM → WARD → CARD → CORD → COLD

(As each letter of the two words in the last example is different, this is the minimum possible number of moves; each move changes one of the letters).

Word ladders are also sometimes referred to as doublets, word-links, paragrams, laddergrams or word golf.

Nice one! Nick Berry does something I’ve often considered doing but never found the time by “solving” word ladders and finding longer chains than might have ever been identified before.

Non Stop Hammer Ti.me

You know how sometimes I make a thing and, in hindsight, it doesn’t make much sense? And at best, all it can be said to do is to make the Internet more fun and weird?

Things that make it awesome:

  • Well, the obvious.
  • Vanilla Javascript.
  • CSS animations timed to every-other-beat.
  • Using an SVG stroke-dasharray as a progress bar.
  • Progressively-enhanced; in the worst case you just get to download the audio.
  • PWA-enhanced; install it to your mobile!
  • Open source!

The British-Irish Dialect Quiz

What is your name for the playground game in which one child chases the rest and anyone who is touched becomes the pursuer?

Pretty accurate for me, although my answers to some of the questions – representing the diversity of places around Great Britain that I’ve lived and some of the words I’ve picked up along the way – clearly threw it off from time to time!

Review of Exeter Gardens

Moderately well-tended but short walk between Oxford Road and Exeter Park, squeezed between Exeter Hall and The Key doctors practice. Nice decking and benches, but otherwise nothing to recommend it except as a route to the park itself.

Review of Grovelands Play Area

This review of Grovelands Play Area originally appeared on Google Maps. See more reviews by Dan.

Small play area with the bare essentials for keeping a small child distracted: swingset, roundabout, small climbing frame with slide. All metal equipment, so gets cold in the winter! Might as well make the extra walk to nearby Exeter Park!

Review of Exeter Park Play Area

This review of Exeter Park Play Area originally appeared on Google Maps. See more reviews by Dan.

Since the 2018 renovation of the play area and the surrounding park, this has gone from being a good to a great place to take small children. Play equipment includes a well-equipped sandpit, multiple climbing frames with monkey bars, firemans poles, and slides, “little ones” area with miniscule frames, musical instruments, see-saw, swings of various kinds including a large tyre swing, rope climbing frames, and a “racing” pair of ziplines. Exercise equipment is also available nearby, as are plenty of benches including picnic benches and a reasonable-sized (free) car park.

Review of Exeter Recreational Ground

Excellent, conveniently central play area for Kidlington. Renovated in 2018 with new play and exercise equipment including trampolines, not one but two ziplines, and a wonderfully imaginatively-imagined sandpit, it’s equipped to keep little ones entertained for hours. There’s also a large field for sports/dog-walking, a community space, and an adequate amount of (free) car parking.

Review of Grovelands Superstore Handy Stores

This review of Grovelands Superstore Handy Stores originally appeared on Google Maps. See more reviews by Dan.

A surprisingly wide selection of goods available at just about any time you might need it, served by friendly staff. Plenty of parking if coming by car, conveniently just off the main road through Grovelands estate.

Codecademy vs. The BBC Micro

This is a repost promoting content originally published elsewhere. See more things Dan's reposted.

If you google “learn to code,” the first result you see is a link to Codecademy’s website. If there is a modern equivalent to the Computer Literacy Project, something with the same reach and similar aims, then it is Codecademy.

“Learn to code” is Codecademy’s tagline. I don’t think I’m the first person to point this out—in fact, I probably read this somewhere and I’m now ripping it off—but there’s something revealing about using the word “code” instead of “program.” It suggests that the important thing you are learning is how to decode the code, how to look at a screen’s worth of Python and not have your eyes glaze over. I can understand why to the average person this seems like the main hurdle to becoming a professional programmer. Professional programmers spend all day looking at computer monitors covered in gobbledygook, so, if I want to become a professional programmer, I better make sure I can decipher the gobbledygook. But dealing with syntax is not the most challenging part of being a programmer, and it quickly becomes almost irrelevant in the face of much bigger obstacles. Also, armed only with knowledge of a programming language’s syntax, you may be able to read code but you won’t be able to write code to solve a novel problem.

So very much this! I’ve sung a song many times about teaching people (and especially children) to code and bemoaned the barriers in the way of the next (and current!) generation of programmers, but a large part of it – in this country at least – seems to come down to this difference in attitude. Today, we’ve stopped encouraging people to try to learn to “use computers” (which was, for the microcomputer era, always semi-synonymous with programming owing to the terminal interface) and to “program”, but we’ve instead started talking about “learning to code”. And that’s problematic, because programming != coding!

I’m a big fan of understanding the fundamentals, and sometimes that means playing with things that aren’t computers: looms, recipe cards, board games, pencils and paper, algebra, envelopes… all of these things can be excellent tools for teaching programming but have nothing to do with learning coding.

Let’s stop teaching people to code and start teaching them to program, again, okay?

Mark Zuckerberg asks governments to help control internet content

This is a repost promoting content originally published elsewhere. See more things Dan's reposted.

Mark Zuckerberg

Mark Zuckerberg says regulators and governments should play a more active role in controlling internet content.

In an op-ed published in the Washington Post, Facebook’s chief says the responsibility for monitoring harmful content is too great for firms alone.

He calls for new laws in four areas: “Harmful content, election integrity, privacy and data portability.”

It comes two weeks after a gunman used the site to livestream his attack on a mosque in Christchurch, New Zealand.

“Lawmakers often tell me we have too much power over speech, and frankly I agree,” Mr Zuckerberg writes, adding that Facebook was “creating an independent body so people can appeal our decisions” about what is posted and what is taken down.

An interesting move which puts Zuckerberg in a parallel position to Bruce Schneier, who’s recently (and especially in his latest book) stood in opposition to a significant number of computer security experts (many of whom are of the “crypto-anarchist” school of thought) also pushed for greater regulation on the Internet. My concern with both figureheads’ proposals comes from the inevitable difficulty in enforcing Internet-wide laws: given that many countries simply won’t enact, or won’t effectively enforce, legislation of the types that either Zuckerberg nor Schneier suggest, either (a) companies intending to engage in unethical behaviour will move to – and profit in – those countries, as we already see with identity thieves in Nigeria, hackers in Russia, and patent infringers in China… or else (b) countries that do agree on a common framework will be forced to curtail Internet communications with those countries, leading to a fragmented and ultimately less-free Internet.

Neither option is good, but I still back these proposals in principle. After all: we don’t enact other internationally-relevant laws (like the GDPR, for example) because we expect to achieve 100% compliance across the globe – we do so because they’re the right thing to do to protect individuals and economies from harm. Little by little, Internet legislation in general (possibly ignoring things like the frankly silly EU cookie regulation and parts of the controversial new EU directives on copyright) makes the Internet a safer place for citizens of Western countries. There are still a huge number of foreign threats like scammers and malware authors as as well as domestic lawbreakers, but increasing the accountability of large companies is, at this point, a far bigger concern.

Bald Eagle Trio Seen Taking Turns Caring For Eggs In Illinois Refuge

Eagle1 webcam showing Starr with Valor I and Valor II

So… two eagles, Valor I (male) and Hope (female) raised some chicks in a nest. Then Valor II (another male) came along and tried to displace Valor I, but he wouldn’t go, so the pair of them both ultimately cooperated in raising Hope’s chicks, even after Hope was driven away by some other eagles. Later, another female, Starr, turned up and Valor I and Valor II are collectively incubating three eggs of hers in the nest.

I’ve known (human) polyamorous networks with origin stories less-complicated than this.

Generating More of My Favorite Aphex Twin Track

This is a repost promoting content originally published elsewhere. See more things Dan's reposted.

“aisatsana” is the final track off Aphex Twin’s 2012 release, Syro. A departure from the synthy dance tunes which make up the majority of Aphex Twin’s catalog, aisatsana is quiet, calm, and perfect for listening to during activities which require concentration. But with a measly running time just shy of five and a half minutes, the track isn’t nearly long enough to sustain a session of reading or coding. Playing the track on repeat isn’t satisfactory; exact repetition becomes monotonous quickly. I wished there were an hour-long version of the track, or even better, some system which could generate an endless performance of the track without repetition. Since I build software for a living, I decided to try creating such a system.

If you’d like to try the experience before you read this whole article (although you should read the article), listen here. I’m sure you’ll agree that it sounds like “more aistsana” without being aistsana.

Spoiler: the secret is Markov chains of musical phrases.

Google’s Three Gender Emoji Future

This is a repost promoting content originally published elsewhere. See more things Dan's reposted.

Coming to Android this year: a third gender option for emojis such as Police Officer, Zombie, Person Facepalming, Construction Worker and People With Bunny Ears.

Revealed by Google in a submission to the Unicode Consortium last week, these changes signal a new direction from Google which has in recent years played ball with other vendors in overlooking Unicode guidelines, in favor of cross platform compatibility.

Above: Google will introduce a distinct appearance for emojis which don’t specify any gender in 2019. Image: Google designs / Emojipedia composite.

In giving public notice via Unicode, Google hopes that other vendors will join them in this effort to standardize many of the emoji which don’t specify a gender.

This builds on an initial few gender inclusive revisions made by Google in 2018.
