ko February-01

While this logo was originally intended for last month and the first daffodils are already starting to bloom, the snowdrops aren’t gone just yet. Unfortunately neither is the war.

A big thanks to @comphilip, whose non-touch improvements (#8859, #8877, #8892) have now made all of the most important functionality available to non-touch users.

KOReader 2022.02 “Україна”

15:55 · Filed under Software

As one of the maintainers of KOReader, a versatile a document and image viewer, I’m proud to announce the latest release.


koreader-2022 02

This month there’s been a fairly big change on PocketBook. The rendering is now handled directly with inkview (#8727) This may result in some visual differences, but in principle it should work more dependably.

Terminal emulator

The terminal emulator has been completely rewritten, and it’s now a real vt52 emulator (#8636).

Speaking of the shell on a device, whether directly on the device through a terminal emulator or using SSH, you might want to put run some programs that aren’t easily available. At this point you have three options:

  1. Compile your own. Doesn’t sound very attractive? I agree. But in case you want to, we have specialized toolchains available. The very same which are used to build KOReader.
  2. Our own @NiLuJe has created precombined bundles of tools for Kindle and for Kobo.
  3. Many a Linux distro such as Debian provides precompiled packages for various ARM architectures. You can use these through a chroot. See some basic info here, which depends on sudo apt-get install debootstrap qemu-user-static schroot. The advantage is that once you have this set up, you can just apt install elinks inside the chroot. See the picture of my H2O running Elinks showing the tweakers.net website. If this interests you, here’s my quickly cobbled together start-debian.sh script to serve as inspiration.

#!/bin/sh
mnt=/mnt/onboard/.adds/debian/debian

mount $mnt/../debian.img $mnt

mount -o bind /dev $mnt/dev
mount -t devpts devpts $mnt/dev/pts
mount -t proc proc $mnt/proc
mount -t sysfs sysfs $mnt/sys
mount -t tmpfs tmpfs $mnt/tmp

chroot $mnt /bin/bash

umount $mnt/dev/pts
umount $mnt/dev
umount $mnt/proc
umount $mnt/sys
umount $mnt/tmp

umount $mnt

KOReader 2022.01 “Union of Utrecht”

10:23 · Filed under Software

As one of the maintainers of KOReader, a versatile a document and image viewer, I’m proud to announce the latest release.


KO january A-01

The Pragmatic Sanction of 1549, as well as the Unions of Atrecht and Utrecht are important markers in the history of the low countries. We should be wary of attaching too much importance to such historical facts, but it’s certainly defensible that the present-day nations of the Netherlands and Belgium sprang from these pro- and anti-Spanish alliances.

The Union of Utrecht is best characterized as a military alliance to defend freedom of religion against a governor who was not prepared to make even a single concession. By signing the Union of Utrecht, the eternal departure from Spanish king Philip had been made official. Formally this didn’t happen until two years later, when Philip decided to declare William of Orange a wanted man. This directly led to the States-General declaring the Act of Abjuration. Not only did the States-General not leave a shadow of a doubt as to their thoughts on the matter, but it made reconciliation impossible. A total victory over the Spanish was the only solution. So it goes.

Book Map and Page Browser

Perhaps the most interesting additions this month are the Book map and Page browser (#8613). The book map shows a map of the content of a book, including the ToC, bookmarks, read pages and non-linear flows. The page browser shows thumbnails of pages. There are quite a few explanatory screenshots in this comment, or of course you can just play with it yourself.

File Browser

The file browser has been expanded with a basic select mode (#8595), making it easier to apply certain actions like deleting or moving to multiple files at once. Additionally, there’s a new display for the number of files and subfolders in folders (#8598).

All the Rest

KOReader 2021.12 “Belisarius”

16:30 · Filed under Software

As one of the maintainers of KOReader, a versatile a document and image viewer, I’m proud to announce the latest release.


KO DECEMBER-01

Around this time of year back in 533, Belisarius defeated the Vandals in the Battle of Tricamarum. Incidentally, there are also some amusing legends surrounding Belisarius’ menorah. According to Procopios, after Belisarius took Carthage in 534 a menorah was part of the loot. But once the lamp arrived in Constantinople, a Jew visiting Justinian pointed out that the religious artifact had brought disaster to every city it had ever been in: Jerusalem had been conquered by the Romans, Rome had been sacked by the Vandals, and Carthage in turn had been conquered by the Byzantines. On second thought, The Menorah of Destruction would’ve been a more exciting name for this release, wouldn’t it? Maybe next year.

Hiding under the unassuming commit message speaking of group operations, the file browser now supports applying actions to multiple files (#8536). It works through the Select files action in the Plus (+) menu.

The event dispatcher can now be used to set a specific font face (#8555).

And last but not least, hanging punctuation has been made just a little more beautiful (#8528).

KO NOVEMBERLEAFS1-01

Did you know that mosquitoes are supposed to crawl up into their winter holes by late September in northern hemispheres? If you didn’t, don’t feel bad, because apparently the mosquitoes don’t know either. The weather’s too mild which is confusing them.

As always there have been many optimizations, most noteworthy this month the improved Japanese support thanks to @cyphar (#8312, #8372, #8446).

As one of the maintainers of KOReader, a versatile a document and image viewer, I’m proud to announce the latest release.


koreader-2021-10-seagull-fs8

You can see many seagulls out and about this time of year, often even far inland.

The biggest news this month may well be @zwim‘s new Autowarmth plugin (#8129), which improves on and replaces all prior implementations. In advanced mode, it offers a smorgasbord of customization options, but luckily there’s no need to dive into the nitty gritty of all the different kinds of dusk and dawn. Who knew there were so many!

Web Apps Opera Bork Edition

18:43 · Filed under Android, Browsers, Opera, Scripting, Software

It’s been 18 years since Opera published their classic bork edition, to protest that MSN would have loaded properly in the browser if only it were served the same code as Internet Explorer.

“Hergee berger snooger bork,” says Mary Lambert, product line manager desktop, Opera Software. “This is a joke. However, we are trying to make an important point. The MSN site is sending Opera users what appear to be intentionally distorted pages. The Bork edition illustrates how browsers could also distort content, as the Bork edition does. The real point here is that the success of the Web depends on software and Web site developers behaving well and rising above corporate rivalry.”

Since I’m a Vivaldi user, today’s the first time I noticed that Chrome on Android artificially restricts installing webpages as apps on the homescreen. Only webpages that specify a manifest.json can receive such a hallowed treatment, instead of every single webpage ever made. For the rest of the internet, there’s only a shortcut. While the situation is not quite comparable, I found the design principle sufficiently distasteful to revive Opera’s classic bork script, in this case specifically targeting the Chrome browser.

You can put it on your website or in your TamperMonkey to remind you when you accidentally open Chrome. The classic result looks like this:
