Just finished watching Borgen: Power and Glory and wanted to give a few thoughts on it.

Initially the most surprising thing about Borgen: Power and Glory is how similar it is to the 2010s series. Who's still here? The ubiquitous Søren Malling is back as a slightly rounder Torben Friis, whose story arc was the standout of series 3. Of course Nyborg is back, and looking much the same; Katrine Fønsmark returns with a more harried visage. A new actor plays Magnus, well-cast; Laura shows up as well, sadly only for a couple of brief cameos. Søren Ravn, also one of the highlights of series 3, is back as well. The themes tread familiar ground of power and negotiation in the political and personal sphere.

Of course, the show had to be updated for the 2020s. One notable absence is the open sexism in the newsroom. In the original series, TV1 newsroom cads would frequently assess female anchors candidly on their looks, unopposed by Friis. Not so here: Katrine Fonsmark now heads up TV1. One may find this a pristinely 'woke' appointment on the surface, but the wrinkle lies in her constant conflicts with her staff. Fonsmark, who was an intransigent rebel under Torben Friis's direction becomes, in effect, "the establishment", makes numerous concessions to pragmatism, and is in turn forced to question herself by young staffers. Mie's request for maternity leave echoes Katrine's similar injunction to Friis in Borgen, when she asks for permission to date Kasper. Fonsmark mishandles this, and the situation explodes in her face through social media. The tweets and messages sent by the characters appear on the screen to advance the plot, unlike the original series where these happened mainly by phone. This is only partially successful: it contributes to a pacing problem with the show.

Fonsmark feuds with the West Asian-looking star anchor, Narciza Aydin, who continually breaks agreements with interviewees in order to focus on pressing human rights issues. Fonsmark falls into the role that Friis formerly had with respect to herself, acting as a constraining force on a maverick reporter. However Narciza is presented rather unsympathetically (and don't you think her name is rather on-the-nose?) Fonsmark, on the other hand, seems to handle the situation rather badly, bulldozing through the office and nakedly asserting her authority. One wonders if the writers are pointing out that this, too, has changed, that these tactics no longer works in a modern office environment; whether, put bluntly, these entitled millenials are not respecting the chain-o'-command. Regardless, the viewer feels sorry for Fonsmark, for whom this conflict with Narciza precipitates a small-scale mental breakdown.

The figure of Asger Holm Kierkegaard is an interesting one. He is something of a nebbish, sharply dressed but lacking street-smarts, and somewhat lacking in a certain masculine strength -- witness his fear of flying and perpetual motion sickness. One wonders if he's intended to replace Kasper Juul. Juul was an archetype of toxic masculinity: promiscuous, troubled, emotionally inarticulate, and supremely square-jawed. Asger is few of these things, though arguably he is promiscuous, entering into an affair with the Greenlandic ambassador's wife. I enjoyed this plotline for its workaday nature: the affair was not glamourized, but rather presented as something ignoble, slightly sordid but still rather touching. The plotline with Tanja I largely did not follow, although Malik was a good character; shame that he had to die to progress the storyline.

Nyborg's storyline is good, though the international politics are sometimes inscrutable. The intense coalition politics of Borgen seems to be largely absent here, which makes sense plot-wise given Nyborg's status as foreign minister rather than PM, but I slightly rued its absence nonetheless. Nyborg's moments with Magnus are great fanservice for viewers of the original series. Their arguments and battles seem wholly believable. Nyborg's descent into cynical political manouevring, aided and abetted by Laugesen, also seems realistic, troubling as it is. Laugesen is well used here as the Dark Lord of spin. Magnus always had a troubled relationship with his mother, so the foreshadowing of the original series plays well here.

The show has been reworked to have an overarching plot for the whole series, rather than a "monster of the week" story structure, as the original series had. This mode is certainly de rigeur for a modern prestige TV series. However the show suffers from questionable pacing. The first 30 minutes of every hour-long episode struggles to keep the viewer's attention as it sets up the drama of the final half. There are facts, figures, and dialogue flying around as fast as the eye can see; blink and you could miss a key plot point. This was the biggest issue with the show to me. It would probably benefit from a second watch.

The basic Puppet template that I use to deploy is this:

class main::my_app($server_name, $owner, $group) {
    $web_root = '/srv/http/my-app'
    $backend_root = '/usr/local/lib/my-app'
    $wsgi_path = "${backend_root}/my-app.wsgi"

    file { $backend_root:
        ensure => directory,
        owner => $owner,
        group => $group,
        mode => '0755'

    apache::vhost { $server_name:
        port => '80',
        docroot  => $web_root,
        wsgi_application_group => '%{GLOBAL}',
        wsgi_daemon_process => 'my-app',
        wsgi_process_group => 'my-app',
        wsgi_daemon_process_options => {
            home => $backend_root,
            python-path => $backend_root
        wsgi_script_aliases => { '/' => $wsgi_path }

Here, wsgi_script_aliases is the really key point, as this is the canonical way to specify the entry point for a WSGI application. The other settings here are mostly form-filling.

  • Permissions are set user-wise to allow syncing code easily from a dev machine.
  • The value of wsgi-daemon-process needs to be unique across the whole server.
  • Name the .wsgi file with the basename of the project.
  • The Flask entry point should be 'app.py' as is customary.
  • This then allows the .wsgi file to import the app directly.
  • You can touch the script file to force a code reload. This will reload all the code, equivalent to a full process kill and restart.

The contents of my-app.wsgi can just be something like this, in the case of a Flask application:

from app import app

application = app

mod_wsgi expects the name application to contain a WSGI app.

At $WORKPLACE I've been observing with interest the different species of interactions that can happen during group chat. Let's divide them into three different areas.

$WORKPLACE_ALPHA -- An agency. This was fun, we set up bots that created a lot of noise in the channel. Remember this was pre-covid, so the chat service in question, HipChat, was a side channel, not a hard requirement for communication. Everything was conducted in a single main channel, all real-time work collaboration went through here. There was no threading. As the team was small, we were all able to keep track of things fairly well, we would sometimes go into DMs if things got complicated.

$WORKPLACE_BETA -- This was a much more stoical workplace Slack, with zero real "banter" and no arguments. I felt quite apprehensive about posting in this Slack. There were only a few channels and little activity; few problems required real-time collaboration to resolve, and if that did become necessary, it was done in DMs. Email was still heavily used here.

$WORKPLACE_GAMMA -- They use Slack as a real "replacement for email", in the way it's supposed to be used. This means a lot of channels, a LOT of threading, heavy reliance on emoji reactions, and while it does feel casual, there's also not much off-topic chat because of the emphasis on signal.

There is still heavy disagreement on the relative merits of coarse-grained vs fine-grained channels. I tend to favour coarse-grained channels, but on the other hand, when you have automations and other non-natural inputs affecting channels, channels can end up functioning more like a specialized Twitter stream or similar, in which case that channel does need to be fine-grained. It's clear that there's a positive correlation between large and coarse-grained channels and off-topic banter. (I don't mean to thereby claim that fine-grained is preferable, or the converse.)

I had to download a bunch of files from a Cloudflare-protected site. Said site is annoying to scrape, because it is heavily using JS to generate unguessable links. Selenium is a possibility but I found that it would be defeated by these Cloudflare CAPTCHAs. Cloudscraper is not feasible either because links are not present in the downloaded HTML directly.

It's an acceptable solution to click the links manually in this case, but then another problem emerges. Firefox's download manager is rather substandard. This isn't an issue in most cases, but in this particular case it was a limiting factor, as downloads would fail and not be retried. Firefox also doesn't limit in-progress downloads, meaning they would saturate the connection and fail.

One possibility is you can use aria2c in daemon mode, and use a Firefox extension to add downloads to it. Aria2c will then queue the downloads and run them in order, with optional retry. The extension embeds something called AriaNg, which provides a nice web interface on top of the aria2c daemon, so it's actually quite friendly. The only tricky part is that you may need to start aria2c yourself. You can do that using the config below, which I took from the Arch wiki.

Here I've been attempting to detail my setup that I revised as of the end of 2021.

DHCP configuration -- This is done using isc-dhcp-server on Debian. I use the network range 192.168.0.x for my internal network, being fairly small. Dynamic DHCP assignments are restricted to the .16 - .127 range. I create host stanzas to store reservations, e.g.:

host sprinkhaan {
  hardware ethernet DC:53:60:F3:A7:FF;

I use option domain-search "phys.solasistim.net" to set up the default search domain for all DHCP clients.

DNS configuration -- This is done using BIND. All hosts receive as their DNS server. This forwards to my ISP's DNS servers (Zen, who have been great so far). Using BIND I am able to create "split-horizon" DNS so that e.g. my Puppet server resolves to an internal IP when requested internally. The main zone file defines all hosts in phys.solasistim.net. (The original idea here was to draw a sharp distinction between physical and virtual hosts, but I've become less certain on this. Still, it's good to use a separate domain from the real solasistim.net.) The downside of this setup is that some duplication of the assignments is needed, specifically the fixed-address setup in dhcpd.conf needs to be essentially replicated in solasistim.zone. This doesn't actually matter much in practice because I don't add hosts very often.

PPP interface -- This is done using pppd and a Draytek Vigor 130. The provider file that I use for pppd is fairly standard. I based it on a useful post from a person called Ruben. The only real difference between the two configurations is that I do have to provide my real account password in chap-secrets.

Firewall configuration -- I use nftables. There's only one really notable thing that I do in nftables, which is a bit complicated, and that's clamp my TCP maximum segment size to my path MTU.

table inet filter {
    # ...
    chain forward {
        # ...
        tcp flags syn tcp option maxseg size set rt mtu
        # ...

You can find more information on this at the nftables wiki. This problem manifests itself in strange ways with some web sites simply timing out when you attempt to connect to them, while most sites work fine. For instance lbc.co.uk and atlassian.net had this strict MTU requirement as of late 2021. There may also be other ways to address this. I know that setting MTU on clients also resolves the issue, but not all devices seem to respect the MTU setting when it's sent in DHCP. It may also be that setting mtu in /etc/network/interfaces will make a difference -- I have never tried this.

Interface configuration -- In /etc/network/interfaces, we create the regular ppp0 interface that is used for WAN access.

auto ppp0
iface ppp0 inet ppp
    provider zen

We create a bridge between two interfaces. One has a Wifi AP and one has a hardware switch.

auto br0
iface br0 inet static
    bridge_ports eno2 eno3

The wifi AP and switch just use their standard Draytek firmware for configuration, which seems to work fine so far.

A few notes/updates: The Vigor 130 has a CLI interface that is accessible via telnet (I believe). This allows some more advanced operations to be performed. There were also some concerns about whether the Zen connection should be Annex A or Annex B. I think we eventually came to the conclusion that it should be Annex A. During the setup of the line, there were frequent connection drops, where the pppd log would read "Modem hangup". These eventually seem to have just gone away without further intervention on my part. I can only assume this was the "line training" phase that is much discussed on UK broadband forums.

There's a genre of blog posts that frequently get linked on Hacker News, which are basically attempts to explain why problems that seem conceptually simple are very complex when attempted within an organization.

I'm referring to these as Chesterton's fence posts. There's an analogy to the eponymous principle: those not directly involved in the day to day materiality of commercial software production cannot see the looming network of past failures that has led to the current abundance of caution. Of course, one could still make an argument that some of these temporal drags on tasks completion are due to organizational dysfunction rather than prudence.

A similar, famous example on HN is that of Dropbox, famously dismissed as something trivially accomplishable via rsync -- a fact that's not wrong, but is nonetheless missing the point.

This is an extract from an unpublished paper. I first heard of this concept on the excellent Talking Politics podcast (RIP).

The Copernican principle (or Copernicus method) is a concept developed by American astrophysicist J. Richard Gott. The principle was first hypothesized by Gott in 1969. It is a probability-based method that allows estimating the potential lifespan of observable objects without any further information, other than the dates of their observation.

The method is based on dividing the hypothetical lifespan of a thing into four quarters. It yields a lower bound on the future lifespan of a thing and an upper bound.

If I am observing the object at the beginning of the middle period, there are three quarters of its lifespan left to go. That means that the future is three times as long as the past. However if one assumes one is at the end of that middle period, the future is only one-third as long as the past.

The canonical example used by Gott is the Berlin Wall. Here are the facts we know in this application:

  • We visited the wall in 1969.
  • The wall is eight years old at that time.

Thus the lower bound for the time-left is given by 8 × ⅓, that is, two and two thirds. This would mean that the earliest date for the "end" of the object, i.e. the collapse of the Wall, is two-thirds of the way through 1971.

The upper bound, on the other hand, is given by 8 × 3, 24 years. This means that the upper bound for the fall of the Wall is 1993.

The Copernicus method would claim that there is a 50% chance that the lifespan falls into these bounds.

As one can see this produces a fairly wide interval: just over 21 years in the case of an 8-year-old object. A 45-year-old object gives an interval of 120 years. In fact, the interval size is given by 8x/3, or equivalently, multiplying by two and two thirds. So these bounds are very large, and remember they're always mediated by the condition that the probability of these bounds being true at all is given at only 0.5.

A similar concept is the `Lindy effect' which was first named by Albert Goldman. Goldman's concept was rather divorced from the one that is current now, though: that concept finds its ancestor in Benoit Mandelbrot. The point can be crudely summarized in the following manner: the future predicted lifespan of a thing varies proportionally to its past lifespan.

It's unclear whether the Copernican method applies to repeated 'observations'. For instance, if Gott were to revisit the Berlin wall in, say, 1975, would the same calculation apply? Do we gain any more information by having that six-year gap, beyond the fact that the wall is now 14 years old?

One can use this information to create heuristics based on how long a future piece of knowledge is likely to be valuable for. For instance, SQL was created in 1974, making it 48 years old as of this writing. The lower bound for SQL's lifespan is thus 2038, making it likely a worthwhile investment. However SQL is an extreme outlier in this scenario. As a matter of simple mental arithmetic, if one decides to focus on current media from 1992, such media has lasted thirty years: one can see the lower bound of its lifespan under the Copernican principle would be ten years.

Of course, this only applies in the scenario where we lack other information. If we assume that certain allegations cast a shadow over Woody Allen's career, it may not be prudent to assume that simply because of the empirical fact of his film presenting itself to consciousness that the Copernican principle applies. The lifespan may be artificially shortened, or behave nonlinearly.

Friends described opposite impulses in Schubert’s personality. Johann Mayrhofer, a poet and librettist, defined it as “tenderness and coarseness, sensuality and candour, sociability and melancholy”. More dramatically Joseph Kenner, another acquaintance, said long after Schubert’s death: “His body, strong as it was, succumbed to the cleavage in his souls, as I would put it, of which one pressed heaven-wards and the other bathed in slime. Anyone who knew Schubert knows how he was made of two natures, foreign to each other; how powerful the craving for pleasure dragged his soul down to the slough of moral degradation.”

It's about that time of the year where I do an upgrade from oldstable->stable, so here's the notes on Bullseye.

Upgrading notes:

  • Dropped npm patch for old node versions.
  • Upgraded syncthing config file to new version v32.
  • Dropped backport spec for gcc-doc now present in bullseye.
  • Dropped MELPA request for haskell-mode now present in bullseye.
  • Upgrading PHP to 7.4.
  • A few emacs packages have been renamed to have an elpa- prefix.
  • Emacs package no longer has a version suffix in its package name, just being emacs instead.
  • /usr/bin/python no longer installed by default -- this is a problem for the non-packaged version of youtube-dl. I haven't found a good solution for this yet. I'm probably going to be evaluating yt-dlp for my needs.
  • Use Debian's /etc/ssl/openssl.cnf, dropping my own.
  • Drop some older pip packages and a few that are more trouble than they're worth.
  • Drop custom package of archive puppet module as now available in bullseye.
  • tt-rss upgraded and was thoroughly broken, not sure how. It doesn't matter too much in my case. I had to manually reapply the database schema.
  • Manually upgrade postgresql clusters to v13.
  • Something new called Tracker exists, I've yet to investigate this.
  • Whonix packages for monero-gui look broken, but the old ones for buster work fine.
  • ddclient Linode support patch refreshed.
  • python-rgain dropped, replace it with pip package rgain3 for anankasm.

Overall this was a fairly smooth upgrade, especially because Puppet only had a minor version bump so it wasn't necessary to purge and regenerate all of the Puppet client certificates (which is normally the biggest pain point).

Yow! x3
