Bumblebees surprise scientists with ‘sophisticated’ social learning

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

First, bees had to push a blue lever that was blocking a red lever… too complex for a bee to solve on its own. So scientists trained some bees by offering separate rewards for the first and second steps.

These trained bees were then paired with bees who had never seen the puzzle, and the reward for the first step was removed.

Some of the untrained bees were able to learn both steps of the puzzle by watching the trained bees, without ever receiving a reward for the first step.

Bee in experimental box

This news story is great for two reasons.

Firstly, it’s a really interesting experimental result. Just when you think humankind’s learned everything they ever will about the humble bumblebee (humblebee?), there’s something more to discover.

That a bee can be trained to solve a complex puzzle by teaching it to solve each step independently and then later combining the steps isn’t surprising. But that these trained bees can pass on their knowledge to their peers (bee-ers?); who can then, one assumes, pass it on to yet other bees. Social learning.

Which, logically, means that a bee that learns to solve the two-lever puzzle second-hand would have a chance of solving an even more-complex three-lever puzzle; assuming such a thing is within the limits of the species’ problem-solving competence (I don’t know for sure whether they can do this, but I’m a firm bee-lever).

But the second reason I love this story is that it’s a great metaphor in itself for scientific progress. The two-lever problem is, to an untrained bee, unsolvable. But if it gets a low-effort boost (a free-bee, as it were) by learning from those that came before it, it can make a new discovery.

(I suppose the secret third reason the news story had me buzzing was that I appreciated the opportunities for puns that it presented. But you already knew that I larva pun, right?)

BBC News… without the crap

Did I mention recently that I love RSS? That it brings me great joy? That I start and finish almost every day in my feed reader? Probably.

I used to have a single minor niggle with the BBC News RSS feed: that it included sports news, which I didn’t care about. So I wrote a script that downloaded it, stripped sports news, and re-exported the feed for me to subscribe to. Magic.

RSS reader showing duplicate copies of the news story "Barbie 2? 'We'd love to,' says Warner Bros boss", and an entry from BBC Sounds.
Lately my BBC News feed has caused me some annoyance and frustration.

But lately – presumably as a result of technical changes at the Beeb’s side – this feed has found two fresh ways to annoy me:

  1. The feed now re-publishes a story if it gets re-promoted to the front pagebut with a different <guid> (it appears to get a #0 after it when first published, a #1 the second time, and so on). In a typical day the feed reader might scoop up new stories about once an hour, any by the time I get to reading them the same exact story might appear in my reader multiple times. Ugh.
  2. They’ve started adding iPlayer and BBC Sounds content to the BBC News feed. I don’t follow BBC News in my feed reader because I want to watch or listen to things. If you do, that’s fine, but I don’t, and I’d rather filter this content out.

Luckily, I already have a recipe for improving this feed, thanks to my prior work. Let’s look at my newly-revised script (also available on GitHub):

#!/usr/bin/env ruby
require 'bundler/inline'

# # Sample crontab:
# # At 41 minutes past each hour, run the script and log the results
# */20 * * * * ~/bbc-news-rss-filter-sport-out.rb > ~/bbc-news-rss-filter-sport-out.log 2>>&1

# Dependencies:
# * open-uri - load remote URL content easily
# * nokogiri - parse/filter XML
gemfile do
  source 'https://rubygems.org'
  gem 'nokogiri'
end
require 'open-uri'

# Regular expression describing the GUIDs to reject from the resulting RSS feed
# We want to drop everything from the "sport" section of the website, also any iPlayer/Sounds links
REJECT_GUIDS_MATCHING = /^https:\/\/www\.bbc\.co\.uk\/(sport|iplayer|sounds)\//

# Load and filter the original RSS
rss = Nokogiri::XML(open('https://feeds.bbci.co.uk/news/rss.xml?edition=uk'))
rss.css('item').select{|item| item.css('guid').text =~ REJECT_GUIDS_MATCHING }.each(&:unlink)

# Strip the anchors off the <guid>s: BBC News "republishes" stories by using guids with #0, #1, #2 etc, which results in duplicates in feed readers
rss.css('guid').each{|g|g.content=g.content.gsub(/#.*$/,'')}

File.open( '/www/bbc-news-no-sport.xml', 'w' ){ |f| f.puts(rss.to_s) }
It’s amazing what you can do with Nokogiri and a half dozen lines of Ruby.

That revised script removes from the feed anything whose <guid> suggests it’s sports news or from BBC Sounds or iPlayer, and also strips any “anchor” part of the <guid> before re-exporting the feed. Much better. (Strictly speaking, this can result in a technically-invalid feed by introducing duplicates, but your feed reader oughta be smart enough to compensate for and ignore that: mine certainly is!)

You’re free to take and adapt the script to your own needs, or – if you don’t mind being tied to my opinions about what should be in BBC News’ RSS feed – just subscribe to my copy at: https://fox.q-t-a.uk/bbc-news-no-sport.xml

RSS > ActivityPub

RSS is better than ActivityPub1.

Photograph of a boxing match, but with the heads of the competitors replaced with the ActivityPub and RSS logos (and "AP" or "RSS" written on their clothes, respectively). RSS is delivering a powerful uppercut to ActivityPub.
A devastating blow by RSS against a competitor 19 years his junior! For updates on this bout as it develops, don’t forget to subscribe… using either protocol.

When I subscribe to content, I want:

  • Resilient failsafes. ActivityPub has many points-of-failure. A notification might fail to complete transmission as a result of downtime, faults, or network conditions, and the receiving server might never know. A feed reader, conversely, can tell you that an address 404’d or the server was down.
  • Retroactive access. Once you fix the problem above… you still don’t get the message you missed: it’s probably gone forever – there’s no retroactive access. The same is true when your ActivityPub server connects with a peer for the first time: you only ever get new content after that point. RSS, on the other hand, provides some number of “recent” items the moment you first subscribe.
  • Simple subscriptions. RSS can be served from a statically-hosted single file, which makes it suitable to deploy anywhere as well as consume using anything. It can be read, after a fashion, in anything from Lynx upwards.

RSS ticks all these boxes. If I can choose between RSS and ActivityPub to subscribe to your content, and I don’t need a real-time update, I’m probably going to choose RSS.

About a month later, Matthias Pfefferle wrote a great post that makes a good “next stop” if you’re on a deep dive…

Footnotes

1 I feel like this statement needs a few clarifications and caveats, but my hot take looks spicier if I bury them in a footnote!

  • By RSS, I mean whichever pull-based basic HTTP you like, be that Atom, JSON Feed, h-entry, or even just properly-marked-up HTML5: did you know that the <article> element is intended to be suitable for syndication use?
  • Obviously I appreciate that RSS and ActivityPub are different tools for different jobs, and there are doubtless use-cases for which ActivityPub is clearly the superior solution.
  • I certainly don’t object to services providing both RSS and ActivityPub as syndication options, like Mastodon does, where both might be good choices.

Young Squirrel Talking About Himself

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

This week, Parry Gripp and Nathan Mazur released Young Squirrel Talking About Himself.

You might recognise the tune (and most of the words) from an earlier Parry Gripp song. The original video for the older version is no longer available on his channel, and that’s probably for the best, but I was really pleased to see the song resurrected in this new form because it’s fabulous. I’ve been singing it all day.

Magical

For World Book Day (which here in the UK is marked a month earlier than the rest of the world) the kids’ school invited people to come “dressed as a word”.

As usual, the kids and teachers participated along with only around two other adults. But of course I was one of them.

This year, I was “magical”.

Cable Gore

If you enjoy a bit of “cable gore”, let me introduce you to the fusebox cupboard at my house, with its plethora of junctions, fuses, breakers, switches, timers, and cabling everywhere! Banana for scale.

A cupboard the height of a fully-grown adult containing several fuseboxes (two large, one medium, and a handful of single-fuse ones, with a mixture of traditional fuses and RCD breakers), a large switch toggling between mains and a generator, a mains timer, and copious wiring. There's a banana in there too.

Out as Poly at Work

During one of the periods today that Facebook wasn’t down, a friend who makes use of the platform shared a Facebook post with me, which read:

Has anyone informed work/colleagues about being ENM and how was it received?

I’ve informed a few colleagues but I am considering informing my team as part of my Team Champion and EDI role.

I’ve been “out” at every one of the employers1 since I entered into my first open/nonmonogamous relationship a couple of decades ago.

I didn’t do so immediately: in fact, I waited almost until the point that coming out was an academic necessity! The point at which it was only a matter of time before somebody thought they’d caught us “cheating”… or else because I didn’t want to have to lie to coworkers about e.g. from whom a romantic gift might have come.

Laptop and mug alongside a notebook and pencil. In the notebook is written "TODO: 1. Come out to colleagues. 2. ???. 3. Profit."
I guess I’ll squeeze in “come out to colleagues” in between the project planning meeting and working on rolling out the server upgrades.

Here’s how it went to be “out” at each of the three full-time jobs I’ve held over that period:

SmartData

We lived and worked in and around a small town, and in our small tight-knit team we all had a reasonable handle on what was going on in one another’s personal lives. By the time I was actively in a relationship with Ruth (while still in a relationship with Claire, whom all my coworkers had met at e.g. office parties and the like), it just seemed prudent to mention it, as well as being honest and transparent.

This photograph – featuring some of my coworkers – was taken in 2005. At that point, they probably all thought of me as a regular, normal person. At least, as far as my relationship structure was concerned. Not in any other way. Obviously.

It went fine. And it made Monday watercooler conversations about “who what I did at the weekend” simpler. Being a small team sharing a single open-plan office meant that I was able to mention my relationship status to literally the entire company at once, and everybody took it with a shrug of noncommittal acceptance.

The Bodleian Libraries

The Bodleian Libraries was a much bigger beast, and in turn a part of the massive University of Oxford. It was big enough to have a “LGBT+ Staff” network within its Equality and Diversity unit, within which – because of cultural intersections2 – I was able to meet a handful of other poly folk at the University.

Dan poses with Bodleian coworkers in front of a party feast in a low-ceilinged office.
This motley crew were exactly as warm and accepting a bunch as you could ask for.

I mentioned very early on – as soon as it came up organically – the structure of the relationship I was in, and everybody was cool (or failing that, at least professional) about it. Curious coworkers asked carefully-crafted questions, and before long (and following my lead) my curious lifestyle choices were as valid a topic for light-hearted jokes as anything else in that fun and gossipy office.

And again: it paid-off pragmatically, especially when I took parental leave after the birth of each of our two kids3.

It also helped defuse a situation when I was spotted by a more-distant coworker on my way back from a lunchtime date with a lover who wasn’t Ruth, and my confused colleague introduced herself to the woman that she assumed must’ve been the partner she’d heard about. When I explained that no, this is a different person I’m seeing my colleague seemed taken aback, and I was glad to be able to call on a passing coworker who knew me better to back me up in my assertion that no, this wasn’t just me trying to lie to cover some illicit work affair! Work allies are useful.

Automattic

I’ve been with Automattic for four and a half years now, and this time around I went one step further in telling potential teammates about my relationship structure by mentioning it in my “Howdymattic” video – a video introduction new starters are encouraged to record to say hi to the rest of the company4.

Framegrab from Dan's Howdymattic video showing him making a "V" shape with his fingers alongside a diagram of his V-shaped relationship.
Some full-on MSPaint grade titling made it into that video, didn’t it?

A convenient side-effect of this early coming-out was that I found myself immediately inducted into the “polymatticians” group – a minor diversity group within Automattic, comprising a massive 1.2% of the company, who openly identify as engaging in nonmonogamous relationships5!

That was eye-opening. Not only does Automattic have a stack of the regular inclusivity groups you might expect from a big tech company (queer, Black, women, trans, neurodiverse) and a handful of the less-common ones (over-40s, cancer survivors, nondrinkers, veterans), they’ve also got a private group for those of us who happen to be both Automatticians and in (or inclined towards) polyamorous relationships. Mind blown.

My relationship structure’s been… quietly and professionally accepted. It doesn’t really come up (why would it? in a distributed company it has even less-impact on anything than it did in my previous non-distributed roles)… outside of the “polymatticians” private space.

In summary: I can recommend being “out” at work. So long as you’d feel professionally safe to do so: relationship structure isn’t necessarily a protected characteristic (it’s complicated), and even if it were you might be careful about mentioning it in some environments. It’s great to have the transparency to not have to watch your words when a coworker asks about “your partner”. Plus being free to be emotionally honest at work is just good for your mental wellbeing, in my opinion! If you trust your coworkers, be honest with them. If you don’t… perhaps you need to start looking for a better job?

Footnotes

1 I’m not counting my freelance work during any of those periods, although I’ve been pretty transparent with them too.

2 Let’s be clear: most queer folks, just like most straight folks, seem to be similarly-inclined towards monogamy. But ethnical non-monogamy in various forms seems to represent a larger minority within queer communities than outside them. There’s all kinds of possible reasons for this, and smarter people than me have written about them, but personally I’m of the opinion that, for many, it stems from the fact that by the time you’re societally-forced to critically examine your relationships, you might as well go the extra mile and decide whether your relationship structure is right for you too. In other words: I suspect that cis hetro folks would probably have a proportional parity of polyamory if they weren’t saturated with media and cultural role models that show them what their relationship “should” look like.

3 Unwilling to lie, I made absolutely clear that I was neither the father of either of them nor the husband of their mother (among other reasons, the law prohibits Ruth from marrying me on account of being married to JTA), but pointed out that my contract merely stipulated that I was the partner of a birth parent, which was something I’d made completely clear since I first started working there. I’m not sure if I was just rubber-stamped through the University’s leave process as a matter of course or if they took a deeper look at me and figured “yeah, we’re not going to risk picking a legal fight with that guy”, but I got my leave granted.

4 If you enjoyed my “Howdymattic”, you’ll probably also love the outtakes.

5 There are dozens of us! Dozens!

Sonarr > Huginn > Slack

I use a tool called Sonarr to, uhh1, keep track of when new episodes of television shows are released, regardless of what platform they’re on (Netflix, Prime, iPlayer, whatever) and notify me so I remember to watch it.

For several years, I’ve used IFTTT as the intermediary, receiving webhooks from Sonarr and translating them for Slack:

A series of webhooks sent from Sonarr to IFTTT to Slack.
This worked for years, but it’s time to retire it.

IFTTT‘s move to kill its Legacy Pro plan2 – which I was on – gave me reason to re-assess this configuration. It turns that the only Pro feature I was using was an IFTTT “filter” to convert the Sonarr webhooks to a Slack-friendly-format.

Given that I’m running an installation of Huginn on my home network anyway, I resolved to re-implement this flow in Huginn and cancel my IFTTT subscription.

A series of webhooks sent from Sonarr to Huginn to Slack.
Raven-powered automation is the new hotness.

This turned out to be so easy I wonder why I never did it before.

First, I created a Webhook Agent and gave the URL to Sonarr.

Then I connected that to a Slack Agent with the following configuration:

{
  "webhook_url": "https://hooks.slack.com/services/...",
  "channel": "#sonarr",
  "username": "Sonarr",
  "message": "*<https://thetvdb.com/?tab=series&id={{series.tvdbId}}|{{series.title}}>*\nNew episodes:{% for episode in episodes %}\n• S{{episode.seasonNumber}}E{{episode.episodeNumber}} {{episode.title}}{% endfor %}",
  "icon": ":tv:"
}
I’ve omitted my Slack webhook URL so you don’t spam me. I tried for far too long to get the pluralize filter to work so it’d say “episode” or “episodes” as appropriate before realising I didn’t care enough and gave up.

Then all I needed to do was re-emit some of the previous webhooks to test it:

Slack chat window showing notifications: (1) a new episode of Resident Alien, announced by IFTTT, (b) the same episode, announced by "Sonarr", (c) two episodes of Marvel's Spidey and His Amazing Friends, also announced by "Sonarr".
As a bonus, I swapped out the IFTTT logo for Slackmoji’s :tv: icon and added the “Sonarr” username, as shown in my code sample.

Now I’ll continue to know when there’s new television to watch3!

I love the power and flexibility that Huginn provides to help automate your life. It does many of the things that I used to do with a handful of cron jobs and shell scripts, but all in one convenient place.

Footnotes

1 I’ve heard there are other uses for the tool. Your mileage may vary. Don’t forget to pay for your content, if possible.

2 Like many others, I originally signed up to the plan under the promise that the price would be honoured forever. Turns out “forever” means “three years”: who knew?

3 It’s especially useful when you’re between seasons or a show is on hiatus to be reminded that it’s back and I should go and watch it. Hey, there’s a thought: I wonder if I can extract the subtitles from shows and run them through a summarising LLM to give me a couple of paragraphs reminding me “what happened last series” if the show’s been on a long break?

Freedom of the Mountain

During a family holiday last week to the Three Valleys region of the French Alps for some skiing1, I came to see that I enjoy a privilege I call the freedom of the mountain.

In black skiwear, Dan looks into the camera from a bench in the snow, his skis upright behind him.
“Mornin’. Let’s go skiing.”

The Freedom

The freedom of the mountain is a privilege that comes from having the level of experience necessary to take on virtually any run a resort has to offer. It provides a handful of benefits denied to less-confident skiers:

  • I usually don’t feed to look at a map to plan my next route; whichever way I go will be fine!
  • When I reach one or more lifts, I can choose which to take based on the length of their queue, rather than considering their destinations.
  • When faced with a choice of pistes (or an off-piste route), my choice can be based on my mood, how crowded they are, etc., rather than their rated difficulty.
A snow-covered Alpine glacier sandwiched into a gully of exposed rocks.
Let’s tear this up, yo.

The downside is that I’m less well-equipped to consider the needs of others! Out skiing with Ruth one morning I suggested a route back into town that “felt easy” based on my previous runs, only to have her tell me that – according to the map – it probably wasn’t!

Approaching the Peak

The kids spent the week in lessons. It’s paying off: they’re both improving fast, and the eldest has got all the essentials down and it’s working on improving her parallel turns and on “reading the mountain”. It’s absolutely possible that the eldest, and perhaps both of them, will be a better skier than me someday2.

I’m not perfect, mind. While skiing backwards and filming, I misjudged the height of an arch and hit the back of the head with it… despite the child shouting to warn me! 😅

Maybe, as part of my effort to do what I’m bad at, I should have another go at learning to snowboard. I always found snowboarding frustrating because everything I needed to re-learn was something that I could already do much better and easier on skis. But perhaps if I can reframe that frustration through the lens of learning itself as the destination, I might be in a better place. One to consider for next time I hit the piste.

My very first “ski-o-cache” was 9 years ago, down in La Tania: this was my second! Found the host easily at the coordinates and found the cache in the third hiding place I tried. It’s quite stiff and hard to extract right now! Needed to wait to return it while some other skiers took pictures of one another at the GZ, but got there in the end. Salutations d’Oxford, en Angleterre. MPLC!

I’m pretty sure that Wally/Waldo, Woof, and Wizard Whitebeard must be out on this mountain somewhere, too.

Geohashing expedition 2024-02-10 51 -1

This checkin to geohash 2024-02-10 51 -1 reflects a geohashing expedition. See more of Dan's hash logs.

Location

Field between Cumnor and Appleton, West Oxfordshire

Participants

Plans

I haven’t hashed for long enough that my home graticule got marked as inactive. I’ve got a little free time this morning, so let’s fix that!

Expedition

It took two attempts to reach this hashpoint.

The first attempt saw me set off around 09:40, with a plan to drive over the world’s stupidest toll bridge (paying 5p for the privilege), park up in Cumnor somewhere, then work down the Cumnor-Appleton footpath before dipping into the fields (which are likely to be fallow this time of year) to claim the hashpoint. I suggested to take the dog, and the 7-year-old child asked if he could join me too, so the three of us with our eight legs set off.

This winter’s seen heavy rain around these parts, and the stream that runs alongside the footpath had broken its banks and flooded the fields. The water had receded, but the ground remained extremely boggy. That kind of thick, wellie-sucking mud that means that if you stop walking for more than a couple of seconds, you might as well give up and say you live there now because your boot is never coming back.

The kid found the going especially-tough, especially after a particularly-deep puddle splashed over the edge of his wellies, and asked to turn back. The dog was finding it a bit challenging too! So we doubled-back and found a geocache a little way off the path. We’ve generally been disappointed by Cumnor’s geocaches and especially this series, finding them to be ill-maintained or completely absent, but it looks like the cache owner has been working on repairing and replacing them towards the tail end of last year and this one was soon found. I drove the dog and child home (back across the toll bridge), then came back out myself (paying the fivepence toll a third time). So began the second attempt:

Unburdened by short-legged dogs and damp-footed kids, I made better progress. At points, the path was completely flooded-out, but this gave me an excuse to walk along the “tramlines” of the cultivator that must’ve been working in the field last year, which put me on a better course to reach the hashpoint. By 11:06 I was well within the circle of uncertainty and declared the mission a success.

Then I plodged back through the mud, changed my footwear, and drove over the toll bridge a fourth time. The attendant, clearly sick of seeing me driving back and forth, took pity on me and let me off without paying yet another 5p piece, so that was nice.

Found after trying a few different hosts while out on an expedition to try and reach the 2024-02-10 51 -1 geohashpoint with the 7-year-old and the dog. The path to the hashpoint is really waterlogged and the little man said his wellies were leaking so we doubled back and retrieved this cache. Extracting the log was a bit of a challenge owing to tune container shape but we managed in the end. TFTC.
