Suggestions & Concerns / Allow markdown for post formatting
« on: June 30, 2020, 01:47:29 AM »
Markdown is much easier to write than BBcode, being little more than structured plain text. It would be nice if we could use it to format posts.

For example, here's some BBcode:

Code: [Select]
[size=1.4em][b]Heading[/b][/size]

I like [b]bold[/b] and [i]italic[/i] and also [url=https://www.youtube.com/watch?v=g1p5eNOsl7I]links[/url].

[size=1.2em][b]Subheading[/b][/size]

[list]
[li]Do you like green eggs and ham?[/li]
[li]I do not like them, Sam I Am.[/li]
[/list]

[code]
#include <stdio.h>
int main(int argc, char **argv) {
    printf("Write in C\n");
}
[­/code]

[tex]\mathrm{e}^{\mathrm{i\pi}} + 1 = 0[/tex]

Now here's the same thing, written in markdown using pandoc's inline LaTeX extension:

Code: [Select]
# Heading

I like **bold** and *italic* and also [links](https://www.youtube.com/watch?v=g1p5eNOsl7I).

## Subheading

* Do you like green eggs and ham?
* I do not like them, Sam I Am.

```
#include <stdio.h>
int main(int argc, char **argv) {
    printf("Write in C\n");
}
```

$\mathrm{e}^{\mathrm{i\pi}} + 1 = 0$

As you can see, the markdown version is much easier to read and edit in its raw form.

However, I don't want to switch between markdown and BBcode. BBcode can do some more complex things that don't suit the simplicity of markdown, and so they should both be available, and it should be possible to combine them. This will be tricky with SMF's awful BBcode parser, but I believe the benefits should be worthwhile.

Technology & Information / OpenBSD 6.7
« on: May 24, 2020, 05:57:36 AM »
OpenBSD 6.7 was released this week. See the full release announcement for the (many, many) improvements made. Aside from the usual incremental progress, the main ones I'm interested in are the adoption of FFS2 as the default filesystem on most platforms, and extra hardware support, particularly for newer Intel Wi-Fi chips and the Pinebook Pro.

I decided to throw a fresh install of 6.7 on my Pine A64+ board. Here's the dmesg:

As you can see, I've been accumulating quite a lot of IPA key combinations. This is helpful for unambiguously representing pronunciation across a variety of different languages. The logic for which combinations produce which letters isn't always consistent, but it makes sense to me (it's usually based on the orthographies of languages I have already learnt, or else visual similarity to the IPA letter).

Arts & Entertainment / Пардисфла reviews Dutch Zappa concerts
« on: April 13, 2020, 12:31:51 AM »
Zappa had a number of good shows in the Netherlands over the years, culminating in the famous "rehearsal" concert in Rotterdam in 1988, in which Ed Mann rehearses the percussion lick from Dickie's Such an Asshole live on stage (as heard on Make a Jazz Noise Here). However, I have not heard most of them, so in this thread I will listen to each one throughout his career and review it here.

This will be markedly different from my previous threads reviewing individual tours, as this thread will span many different tours with many different bands across his entire career.

Unfortunately, no Dutch concerts between 1971 and 1976 have recordings available, and so—in order to avoid the omission of a seminal part of Zappa touring history—I will be substituting the shows for several tours with adjacent ones from neighbouring countries (the UK in 1972, Belgium in 1973-74). After all, Brussels is an enclave within Flanders, which everyone knows belongs rightfully to the Dutch.

See ye soon for the first show!

Technology & Information / Axe-Parrett Canal
« on: April 05, 2020, 05:21:00 PM »
Currently, the two neighbouring EU states of France and Ireland must route ships around Land's End in Cornwall to transport goods without them leaving and re-entering the EU (and thus being subject to foreign taxation). This is clearly not ideal, but I have just the solution!

Within the county of Somerset, England, the River Parrett flows into the Bristol Channel through low-lying land via Bridgwater down from the town of Langport, where it reaches an elevation of about 10 metres. From there, its tributary the River Isle continues up to reach an elevation of 20 metres shortly before the town of Ilminster.

Meanwhile, in Devon, the River Axe flows into the English Channel at Axmouth, coming down (somewhat more steeply than the Parrett) from Axminster, where it is also at an elevation of about 20 metres.

Now, the Panama Canal has established an engineering precedent for passing heavy maritime loads through changes in elevation of up to 26 metres. Also, Ilminster and Axminster are separated by about 20 kilometres of relatively low land between two mountain ranges. The highest elevation in this section is about 100 metres, near the town of Chard, which lies in Somerset close to the border with Devon.

My proposal is this: Widen and deepen the Parrett, Isle and Axe rivers along this course to permit the passage of typical container ships. Then, construct a 20-kilometre canal in a new cutting between the towns of Ilminster and Axminster, to connect the two river systems. The pièce de résistance of this engineering project would be a short 1-kilometre tunnel under the highest point on the route, to avoid slicing the eastern half of Chard in two while permitting a typical 65 metres of air draft for passing ships.

Naturally, some additional work would be needed, for instance at Bridgwater where a new route around the town would be required to avoid the demolition of any existing low-level bridges, and to carry the M5 motorway over the route with enough clearance for container ships to pass. But these are all solvable problems with historical precedent.

Once this project is complete, passing ships will be subject to a nominal tariff rather than being treated as leaving and re-entering the EU, and thus avoid any taxation on their cargo. Maritime traffic between Cherbourg and Dublin will then be able to avoid the lengthy detour around Land's End, delivering economic benefits for the EU on par with Boris Johnson's proposed bridge to Northern Ireland.

For an illustration of the topography involved, see this topographic map of Devon.

Arts & Entertainment / Reviewing the reviewer: The Christgau picks
« on: June 14, 2019, 07:46:57 PM »
In the grand tradition of threads about listening through a set of recordings with a collective theme, I have decided to review all of the top album of the year picks from the supreme cuntface himself, Robert Christgau. As it turns out, these are all albums I have never heard before, which makes things a lot more interesting. Christgau tends to be pretty scathing about the sort of music I do like, so who knows how this will turn out?

For each album, I will first listen to the music and review it, and only then read Christgau's review and add my comments (except for the first pick, which I've already glanced at his review for). I will then give his grading of the album a grade. Sounds fair, right?

The list of albums included is nicely collated from his yearly (since 1974) Dean's Lists on Wikipedia, for those following along at home.

See you (hopefully) tomorrow for a review of Joy of Cooking, FES.

The forum and homepage were offline from about 00:07 to 06:05 UTC on 2019-01-23. The cause was the database partition running out of disk space while the admin was asleep.

In the short term, I've just added more space. The long-term fix is to set up proper monitoring so we know well in advance when this sort of thing is going to happen.
