+title: How I read things on the Internet now (no, of course I don't leave the terminal!)
+description: >-
+  I've been sprucing up how I follow what's happening on the Internet. I can
+  now read all the things I want to read pretty efficiently, and enjoy doing
+  it, which is exciting.
+pubDate: 2025-01-19
+---
+
+## The problem
+
+I like to read things on the Internet sometimes. Or listen to things. Or watch
+things.
+
+Some interesting people write blog posts. Some beautiful people make music. Some
+silly people make comedy sketches. Sometimes my friends are sharing stuff with
+their friends, which means me (WIP on that front: I'll get back to that).
+
+I want to know about it. I want to read interesting things that will educate
+me. I want to hear beautiful music. I want to hear about what my friends are up
+to.
+
+I can't read everything as it comes in, it's too much: I'll need to sift a lot
+of it out quickly. I'll need to sift through it regularly to stay on top of it:
+like, several times a week, if not daily. And sometimes, while I'm doing my
+daily sifting, I'll find something I really want to read, but I haven't got
+time right now: I'll save this for the weekend.
+
+For a while, I've been hosting [CommaFeed][commafeed] on [PikaPods][pikapods].
+This has been OK ([OMG, RSS is cool][rss]), but the interface is just clunky
+enough to make it a chore to use. That means I don't sift through stuff
+regularly, and that means my feed piles hundreds of unread posts high.
+
+It also hasn't been any good for distinguishing between stuff I don't want to
+read *ever*, and stuff I don't want to read *right now* but will get round to
+later. I could in theory use the bookmarking feature built-in to my browser,
+but removing things after I've read them is too clunky, so I don't do it.
+
+## The solution
+
+Every morning, I open my terminal and run [newsboat][newsboat].
+
+![newsboat showing how many unread posts I have at a glance in the opening view](./newsboat.webp)
+
+I know the unread count is pretty fresh, because I've set up a systemd service
+to run newsboat at startup to fetch the feeds.
+
+I press `l` twice to open a post. Then I press `n` to navigate to the next
+unread post until I run out of unread posts.
+
+![newsboat displaying a post](./newsboat-post.webp)
+
+If I encounter something I want to read later, but don't have time right now, I
+press `b`, which runs a home-made bookmarking script. Here it is:
+
+```bash
+### readlater.sh ###
+
+# newsboat passes a few arguments:
+# the first one is the post URL
+url="$1"
+
+# I turn the URL into a suitable filename
+filename=$( \
+  echo $url | \
+  sed "s/.*:\/\///" | \
+  sed "s/\//./g" | \
+  sed "s/\.html\$//g" \
+)
+filename="$filename".html
+
+# If I've already got this in my reading list,
+# I don't add it again
+if [[ -a "$HOME/readlist/unread/$filename" ]]
+then
+  exit 0
+fi
+
+# Otherwise, I download the post with curl
+# and pipe it to a file in my reading list
+# folder, ~/readlist/unread
+curl "$url" > "$HOME/readlist/unread/$filename"
+```
+
+I can also run this script manually and pass it a URL of my choice at any time,
+say, if I find an interesting article while browsing the Web.
+
+When I want to read from my reading list, I run `readnow.sh`, which simply
+opens my reading list folder, `~/readlist/unread`, in my terminal file browser
+of choice: namely, [ranger][ranger].
+
+![ranger showing the contents of my reading list with a preview](./ranger.webp)
+
+Although ranger has a preview, I'll typically open the file up in my terminal
+web browser of choice, which is [w3m][w3m] (plus a couple of custom
+key-bindings). I've configured this to be my preferred web browser in ranger by
+shifting it to the top of the list of HTML browsers in
+`~/.config/ranger/rifle.conf`.
+
+```conf
+### ~/.config/ranger/rifle.conf ###
+
+...
+
+ext x?html?, has w3m,               terminal = w3m "$@"
+ext x?html?, ...
+
+...
+```
+
+Having configured my default web browser in my ranger config, all
+I need to do is press `l`.
+
+![A post displaying in w3m](./w3m.webp)
+
+No ads, no cookie popups, no giant banner images taking 2 seconds to load and
+shifting the content all over the place: just the text I want to read. Isn't it
+beautiful?
+
+Once I'm finished reading the post, I'll press `q` to quit w3m and return to
+ranger. Assuming I don't need to read it again, I'll press `dm` to move the
+post to `~/readlist/read` - my way of marking a post as 'read'.
+
+I've done this by writing a super simple script, `markread.sh`:
+
+```bash
+### markread.sh ###
+
+filename="$(basename $1)"
+
+if [[ -a "$HOME/readlist/unread/$filename" ]]
+then
+  mv "$HOME/readlist/unread/$filename" "$HOME/readlist/read/$filename"
+  echo "Marked $filename as read."
+else
+  echo "I couldn't find a file in ~/readlist/unread with the name: $filename"
+fi
+```
+
+...and hooking it onto the custom keybinding, `dm`, in ranger:
+
+```conf
+### ~/.config/ranger/rc.conf ###
+
+...
+
+# map `dm` to run markread.sh in the shell, providing the active filename
+# as the first and only argument
+map dm shell markread.sh %f
+
+...
+```
+
+## The result
+
+I can now keep up to date, and I enjoy doing it.
+
+I get not everyone likes to live in the terminal. I think the key takeaways
+are:
+
+- Make it really easy to sift through new posts
+- When you sift, sift through every post, and for each one, either read it
+  straight away, or add it to your reading list
+- Sift daily
+- Make it really easy to add things to your reading list
+- Make it really easy to browse, read things, and mark things read in your
+  reading list
+- Set aside time to catch up on your reading list
+- Make the whole thing joyful (both because joy is good, and because you won't
+  do it otherwise)
+
+## Next steps
+
+I still haven't really figured out social media. I'd like to stay up to date
+with what my friends are doing, especially the ones I don't see very often. If
+my friends are posting stuff on the Internet, I'd love to see it.
+
+I still need to know:
+
+- Are my friends posting stuff on the Internet?
+- If so, where?
+- What's the best way of subscribing to their posts - even if they live on
+  different websites and in different formats?
+- What's the best way of sending and receiving comments/replies/reactions?
+
+TBC. Answers on a postcard please.

+title: Why scientists need philosophers
+description: This is a practice essay, OK? Don't shoot me if it's no good.
+pubDate: 2025-01-24
+---
+
+I've recently been working at a
+[Philosophy of Science MOOC]([phil-sci-coursera]) on Coursera, the online
+courses website. Later on, they set you an exercise to write a short essay
+addressing how philosophy can contribute to science.
+
+So this is my punt. Life is too short to revise or, hell, even research this, so
+don't take any of this as my settled opinion or as my best work. Whatever. With
+that caveat in mind, it might still be entertaining at least, or maybe even
+spark some thoughts.
+
+---
+
+Walk into a particular room in the Science Museum in Kensington, and you will
+find yourself enveloped in a cavern of ironmongery and miscellanea. The shelves
+droop under the weight of bolts, files, screws, bits, grinders, saws,
+protractors, clamps and pins. The inventory scrolls endlessly past you, voices
+reciting the lists of trinkets like an incantation.
+
+This is the workshop of James Watt, meticulously reconstructed from the
+original as it was left in his home in Birmingham after his death. This
+entrancing space invites you to imagine a tireless creative, endlessly
+tinkering away at his next contraption.
+
+And yet for all that - and for all his immense valorisation as the lynchpin of
+Britain's industrial revolution - Watt was reluctant to think of himself as the
+engineer everyone else loved. He aspired to be remembered not as an engineer
+but as a scientist.
+
+To understand why James Watt, one of the most admired engineers who ever lived,
+wished he were famed as a scientist instead, is to understand something
+essential about modern Western thought.
+
+In Watt's lifetime, scientists increasingly became the elite of society. In the
+nineteenth and twentieth century, this trend only gathered pace. We constructed
+our modern public health infrastructure on the advice of pathologists and made
+medicine scientific. We funded scientific expeditions to map the world, even to
+its remotest corners (in part to help us conquer it). We adopted radical new
+economic policies in response to scientific economic theories. We built vast
+infrastructure networks to communicate waves of invisible energy discovered by
+pioneering physicists, and built nuclear plants to generate more of the stuff
+by means of nuclear science. We even designed social programmes on the basis of
+scientific anthropology. By the end of the twentieth century, scientists were
+our prophets, priests and kings. Or so we thought.
+
+In the 1990s, at the so-called 'end of history', it was assumed that there
+would be no more need for social upheaval. Humanity had arrived at the ideal
+system of social organisation. And among other ideologies - secularism,
+libertarianism, democracy - an essential part of the package is that science
+was our ultimate and incontestible way of securing knowledge about the world.
+
+Yet now, that certainty is broken. Religious fundamentalism, whether Christian,
+Muslim, Hindu, or else besides, is politically empowered in many places,
+together with its rejection of science.
+
+At the same time, the myth of science is ever more punctured. The supposedly
+scientific West has increasingly come to appreciate that their scientific
+heritage also includes much we would rather ignore - phrenology, race science,
+systematic blindness to female bodies in medicine.
+
+Meanwhile, scientists themselves are noticing that their holy calling has
+turned out to be rather less holy than they had hoped. They find science
+pulled between the competing demands of truth and tenure. Scientific knowledge
+is locked behind the paywalls of exclusive journals, which even many academics
+struggle to access, never mind the general public.
+
+What then for science in the twenty-first century?
+
+Yet there is another story available. It starts with confessing that the old
+stories got things wrong in important ways. When we put ideology aside, science
+has not been on an uncontested march to universal acceptance since Galileo.
+There has been continual change, continual conflict, continual readjustment of
+our ideas to the changing demands of the age.
+
+In Galileo's day, it may have been a fight to establish that there was much to
+be seen by simply looking. As empirical observation started to prove its worth
+in the early modern period, thinkers wrestled with new problems: how to
+reconcile the evidence of Scripture with the evidence of the senses? How to
+understand how sensation can give us knowledge at all, granted that any
+observer may be vulnerable to illusions, tricks and dreams? And if that's how
+sense data work, what then for our mathematical or logical knowledge, which
+seems to already bind the world even before we start experiencing it?
+
+This centuries-long struggle culminated in the work of Kant, who in his 1786
+magnum opus, the _Critique of Pure Reason_, set out a masterful - if infamously
+obscure - system, which enabled thinkers to understand just how empirical
+knowledge might work.
+
+Yet two generations later, Charles Darwin lit the flame under new controversy
+about the relationship between scientific and religious knowledge. His bizarre
+and wildly imaginative theory of evolution by natural selection challenged the
+Genesis Creation accounts, and this was soon to be followed up with the theory
+of tectonic shift.
+
+Some said that where scientists contradicted the authority of Scripture, the
+word of God must always win. Others said that science alone had the keys to
+knowledge, and if what the Bible said couldn't be proven scientifically, then
+it couldn't be accepted. Some said that science and religion were two
+incommensurable attempts to study the same subject matter, while others said
+that they covered completely separate spheres.
+
+Gradually, all of these views moved to the extremes. Now, most people (though
+not all) agree that science and religion have overlapping spheres, and can
+inform one another, but neither the Book of Nature nor the Book of Scripture
+has the decisive final say.
+
+Now, in our post-Christendom Western context, it's more important than ever to
+understand how science and religion can talk to one another. Religious
+minorities - as all religions now are in the West - are vulnerable to the risk
+of becoming epistemic islands, cut off from the knowledge of the rest of the
+community, unless we can find ways that science can talk across creedal
+differences.
+
+We need, too, for scientifically marginalised communities, such as non-white
+people, whom science has ignored, or worse, to be more tightly integrated into
+science, both so that knowledge might increase, and so that the benefits
+knowledge gives might be fairly shared.
+
+In light of these urgent needs, today's philosophers are considering science
+not just as an epistemic problem, but as a social problem. As philosophers once
+established science as the bedrock of modern knowledge, so philosophers today
+have the task of figuring out how science can glue together our societies.
+
+Science has been at its most dangerous when it hasn't been questioned. At all
+times, as long as we practice science, we need to consider what it means, what
+it means to do science well, how it can generate knowledge, and how it ought to
+be used as a powerful instrument of change.
+
+And perhaps that might justify James Watt in his obsession to be seen as a
+scientist: since we can't get by just with practitioners. We need people who
+can see our practices from the outside and shine a mirror back on us. If we
+want science, then we need philosophers.
