Adventures in Unicode's math plane

The Unicode charset has a complete plane (a subset of codepoints) dedicated to the humungous plethora of symbols used in math formula and definitions. For some reason, the creators felt that re-defining the usual latin characters in varios stylings was a necessity. I won't argue on that.

We can benefit from this odd inclusion to use special text effects in places where it's not possible, e.g. social networks. So, given that we have this text snippet:

From George Orwell's 1984:

He gazed up at the enormous face. Forty years it had taken him to learn
what kind of smile was hidden beneath the dark moustache. O cruel, needless
misunderstanding! O stubborn, self-willed exile from the loving breast! Two
gin-scented tears trickled down the sides of his nose. But it was all
right, everything was all right, the struggle was finished. He had won the
victory over himself. He loved Big Brother.

We can play with several styles. For example, using bold serif symbols:

Please take note that what you see is completely dependent on the fonts you have installed in your system. For example, on my Ubuntu 19.10 I don't see the h letter. I have no clue on why (I also don't give a damn).

New ActivityPub support in Gruta

I have implemented partial ActivityPub support in pygruta, the Python port of my decades-old web CMS software Gruta. It has been implemented as two big blocks; the first one is a daemon process that, getting queries redirected from the web server,

  • Answers to webfinger GET method requests,
  • Answers to ActivityPub actor (user) GET method requests,
  • Accepts (and confirms) follow commands from POST method requests and registers the follower,
  • Accepts un-following commands from POST method requests and de-registers the follower,
  • Accepts messages (direct or public) from any ActivityPub user from POST method requests and stores them in a special topic as Gruta stories.

On the other hand, a command-line tool (triggered by cron) does the following:

  • Collects a story feed (the same set of stories that would be used in an ATOM or RSS feed) and sends it to all registered followers as public ActivityPub notes.

As of now, you cannot answer to a message sent from this network. I've yet to find a way of doing it, but most probably it would be by writing a standard story and using a special destination field or searching for a mention inside the story content matching the @user@host standard way of mentioning.

It has been a very tedious work, as the documentation is poor and confusing and you never get helpful feedback from errors. I did the development against different software (Mastodon, Friendica and Pleroma), but only got it working for the first one (it's the most common out there, though).

You can follow my id @angel@triptico.com from this network.

A function to decode utf-8 in streaming mode

This is my C language function to decode utf-8 into wide characters, a byte at a time. It also detects encoding errors.

/**
 * mpdm_utf8_to_wc - Converts from utf8 to wchar (streaming).
 * @w: convert wide char
 * @s: temporal state
 * @c: char read from stream
 *
 * Converts a stream of utf8 characters to wide char ones. The input
 * stream is read one byte at a time from @c and composed into @w
 * until a Unicode codepoint is ready. The @s integer keeps an internal
 * state change and must be set to 0 before the stream is read. It
 * detects encoding errors; in this case, the special Unicode
 * char U+FFFD is returned.
 *
 * When 0 is returned, a new wide char is available into @w. If
 * the stream is interrupted in the middle of a multibyte character,
 * the @s state variable will not be 0.
 */
int mpdm_utf8_to_wc(wchar_t *w, int *s, char c)
{
    if (!*s && (c & 0x80) == 0) { /* 1 byte char */
        *w = c;
    }
    else
    if (!*s && (c & 0xe0) == 0xc0) { /* 2 byte char */
        *w = (c & 0x1f) << 6; *s = 1;
    }
    else

Sobre la creaciรณn de canales de Telegram

Hace unos dรญas investiguรฉ para un amigo cรณmo crear y usar canales de Telegram y le enviรฉ este email contรกndole lo que he averiguado. Lo adjunto aquรญ para que no se pierda:

Hola. He investigado sobre los canales de Telegram y cรณmo automatizarlo. Como siempre todo es complicado y confuso. Te lo cuento aquรญ porque maรฑana seguro que se me ha olvidado.

Lo primero es crear un canal. Eso ya lo has hecho.

Lo segundo es crear un bot. Es una especie de usuario de Telegram que no es un usuario pero que puede postear en canales. Para crearlo hay que hablar con otro bot que se llama BotFather. Ahรญ hay que darle comandos tipo IRC para crear tu bot (sรญ, es asรญ de confuso). Hay que mandarle el mensaje /newbot y รฉl (como en un chat robรณtico) te pide el nombre del bot y el nombre del usuario del bot (no sรฉ muy bien cuรกl es la diferencia ni por quรฉ hacen falta dos nombres y por quรฉ no puedes ponerle el mismo). Despuรฉs de esto te da una cadena de texto mรกgica que es un identificador autenticado del bot para poder postear desde fuera.

Luego tienes que ir al canal y aรฑadir al bot como administrador. Solo funciona si lo haces desde el mรณvil, desde el ordenador no lo he conseguido. Tienes que buscar el nombre del bot desde la lupa porque no te sale automรกticamente tu lista de bots.

Una vez hecho esto un par de veces (a la primera no me ha funcionado), ya le puedes mandar comandos al bot por HTTP para postear en aquellos canales en los que estรก autorizado. Esto se hace con una query como la que sigue:

 https://api.telegram.org/botIDENTIFICADOR_DEL_BOT/sendMessage?chat_id=@CANAL&text=Hola%20caraculo

Esto se puede hacer directamente con el comando curl del Linux o desde algรบn programa, es una peticiรณn HTTP normal.

Eso publica en modo texto. Hay un modo especial HTML que es MUY limitado y solo acepta negrilla, cursiva, enlaces y poco mรกs. Con eso hay que montรกrselo todo. En concreto, NO acepta <p> para separar lรญneas ni tรญtulos <h1>, <h2>, etc ni nada de eso, asรญ que hay que hacer una especie de conversiรณn (no es que ignore los tags, es que casca y te rechaza el envรญo).

Leyendo por ahรญ he descubierto que el modo HTML sรญ acepta cortes de pรกrrafo pero hay que meterlos a pelo, es decir, metiendo %0A (ascii del line feed). Para aรฑadir imรกgenes hay otro truco, que es ponerlas como enlaces (NO como imรกgenes). Si dejas el texto del enlace vacรญo o con un espacio lo ignora. La gente dice que le pone un carรกcter Unicode especial que es el "separador que no ocupa espacio" pero a mรญ me lo rechaza.

Este comando funciona y genera una entrada mรกs o menos bonita:

 curl 'https://api.telegram.org/botBLA_BLA_BLA/sendMessage?chat_id=@nutriguia&parse_mode=HTML&disable_web_page_preview=false&text=<b>Title</b>%0AThis is a <i>test</i>. <a href="https://triptico.com/img/mp.png">ยท</a>'

Asรญ que se podrรญa hacer un programita que instalado en un cron coja, por ejemplo, el feed ATOM o RSS de Nutriguรญa, magree un poco las entradas, las deje aceptables para el Telegram y las envรญe con sendas peticiones HTTP como las que te he comentado arriba.

Quizรก alguien ha hecho ya ese programa, no he investigado mรกs allรก.

On selecting text in the Minimum Profit Text Editor

As this is a question I have to answer periodically here are my final words on it.

The Minimum Profit Text Editor has three selection modes: "movement", "block" and "vertical".

The "movement" one is the way of selecting text that is implemented everywhere and is somewhat of a standard: by pressing the shift key and using any of the movement actions (left, right, word left, word right, up, down, page up, page down, beginning of line, end of line, beginning of document or end of document) or by left clicking and dragging with the mouse. Additionally, you can right-click and drag to extend the selection. Once the block is marked any movement key deselects it. Typing something replaces the selection. Hitting del or backspace erases the selected text. Though this mode is what new users expect, it works weakly on non-GUI interfaces because of lacking or defective support in the underlying libraries and systems.

The "block" selection mode is an older style one (and the first one that MP had): by pressing a key (f9 by default) you mark the beginning or end of the marked text. The selection survives any movement (indeed, it's the only way block selection can be done, by moving to another place and marking the other end) and you can extend the block above or below whenever you want. Replacing and erasing works as expected. Additionally, most operations like search, replace, etc. only apply to the marked text if there is one (this is very useful). The selection only disappears when copying, erasing, replacing, mouse-clicking or unmarking (by pressing the f8 key). This is the way I copy and paste; I never use the standard way (I know you don't care).

The "vertical" selection mode also works by marking the beginning or the end of the block, but the selection forms a square shape (x, y to x', y') instead of a line-flow one. By default it's done by hitting ctrl-b. The selection can also be extended repeatedly. As in "block" mode, marked text is disabled after copying or by pressing f8. I never use this option and never did (it was implemented by a fellow programmer).

I agree that the "movement", "block" and "vertical" terms are a sloppy way to describe the operations they do.

Why the Minimum Profit Text Editor is not part of Debian

Yesterday I received three different emails asking me why the Minimum Profit text editor is not included in the Debian linux distribution, a question most probably arised due to the recent release of Debian 10. One of the messages even mentioned that it was called mped there, so he must be a very long time user. Anyway, this is a briefing I gave to a user many years ago (2011):

"And regarding linux distrubutions, I know for sure that it's at least part of Gentoo, Puppy Linux and there is even a *BSD port. It also used to be part of Debian, but I had very bad luck there: someone picked it up and became its maintainer, for later forgetting about it and not following version updates. It happened that when the first stable distribution that became UTF-8-enabled by default (don't remember what was its name, maybe sarge), "Upstream" MP was already at its 5.x version, but Debian got still a 3.x, which had the very nasty habit of destroying UTF-8 files. I posted an RC bug regarding this, but it went released anyway, probably mangling every user file that tried it and most probably losing users. Later, the maintainer was considered as Missing-in-action and the package orphaned; another time later the QA equipment took control and updated it to the latest 5.x version, what made me happy for a time; but just on the verge of the release of current stable version the package was deleted with the message "few users; alternatives exist" and disappeared from their database. This last version is still what got migrated to Ubuntu, where it still exists, but probably unmaintained and forgotten."

Those "latest stable versions" of Minimum Profit and Debian I talked about in that paragraph were the ones back on 2011 (whichever they were). MP is no longer on Ubuntu and I don't know nor care if Gentoo or Puppy Linux even still exist (they were popular distributions those days).

Anyway, the Minimum Profit text editor is alive and well and having periodic updates. It's public domain software and can be built from source code for virtually any platform. Portable (i.e. no installation needed) binaries exist for MS Windows (32 or 64 bits, GUI or console versions). It's probably better that the text editor you are using now.

I also think that few users, alternatives exist is a reason can be given for the deletion of most of us.


MP: Not only for text-editing but also for pipe-turning.

Disk partitions and UDF formatting on MS Windows

Partition manager

Open cmd.exe and run

 diskmgmt.msc

Formatting a disk as UDF

 format x: /fs:UDF

Using the UDF filesystem in USB sticks

The best way of using USB sticks for sharing information between Linux and MS Windows systems is to have them formatted with the UDF filesystem. On MS Windows it's fully supported (read-only on XP, though) while on Linux is much better that FAT monstrosities because permissions and owners are preserved.

To format an USB stick, use the mkudffs program:

 mkudffs -b 512 --media-type=hd /dev/{full disk device}

You also probably want to delete all partitions in the stick to avoid it being wrongly detected.

Someone said these UDF-formatted sticks also work correctly on MacOS (didn't try).

Estos nรบmeros son cadenas de cuatro dรญgitos que sirven como contraseรฑa para telรฉfonos mรณviles, tarjetas de crรฉdito y otros dispositivos que potencialmente contienen informaciรณn sensible. Si tu nรบmero estรก en esta lista, se considera vulnerable y deberรญas cambiarlo inmediatamente.

Cรณmo ponerle una radio normal a un Jeep KJ / Liberty / Cherokee

Hace falta lo siguiente:

  1. Un adaptador ISO para alimentaciรณn y altavoces (10,03 โ‚ฌ)
  2. Un adaptador para la antena (7,99 $)
  3. Un adaptador/carcasa para encajar la radio (11,98 $)
  4. Una radio (35,63 โ‚ฌ)

La radio vale cualquiera siempre que lleve doble conector ISO. Como yo no querรญa CDs ni mierdas, comprรฉ la mรกs barata, que tuviera radio, tarjeta SD y USB. Ya que los Jeep llevan el reloj en la radio y la vamos a sustituir, tambiรฉn conviene que la radio tenga reloj.

Ademรกs de lo mencionado arriba tuve que comprar cuatro tornillos para enganchar la radio a la nueva carcasa. En casa siempre tengo un millรณn de tornillos pero como era de esperar no me valรญa ninguno.

Para cambiarla hay que seguir los pasos obvios:

  • Montar la radio en la nueva carcasa.
  • Enchufar el nยบ 1 y el nยบ 2 en la radio.
  • Quitar el cenicero de al lado de los cargadores de mechero y sacar el tornillo que hay ahรญ.
  • Tirar para sacar todo el frontal.
  • Sacar la radio quitando los cuatro tornillos de las esquinas (que nos valdrรกn luego para poner la nueva carcasa).
  • Quitar el cable de datos y el de antena.
  • Conectar el nยบ 2 al cable de la antena.
  • Conectar el nยบ 1 al cable de la radio.
  • Meter con cuidado, atornillar y volver a colocar el frontal.

La รบnica contrapartida es que los mandos del volante ya no sirven, pero puedo sobrevivir sin ellos.

BtSync

Es un bittorrent personal, que hace que puedas compartir archivos que se sincronizan en todos tus ordenadores, a la forma de Dropbox o Google Drive. Una de las diferencias es que, al no depender de una ยซnubeยป externa, no tienes ninguna limitaciรณn de espacio de almacenamiento ni nadie puede mirar lo que guardas.

Estรก basado en ยซsecretosยป; cada vez que se instala el programa en un equipo, pregunta si ya tienes un secreto (proporcionado por instalaciones previas) o si crea uno nuevo. Todos los equipos que compartan un secreto comparten los archivos asociados. Un secreto es sรณlo una cadena larga de caracteres.

No se limita a un directorio; puedes tener todos los que quieras con sus correspondientes secretos, asรญ que puedes compartir con diferente gente diferentes directorios, incluso con permisos limitados (es decir, por ejemplo, puedes compartir conmigo tu carpeta de MP3 en modo sรณlo lectura, de forma que yo no pueda borrarte ni aรฑadir nada).

Este es el secreto (sรณlo lectura) para mi colecciรณn de imprescindibles de mรบsica clรกsica, que siempre mantengo por debajo de 1GB y que cambio a menudo:

 R2FWMUHX7AX5CMJ7NZHR5PFP5FN5ICAKR

Para usarlo, instala BtSync, crรฉate una carpeta y dile al BtSync que la aรฑada dรกndole este secreto.

Existen versiones para MS Windows, Mac y Linux (no es software libre).

HOWTO install Linux from grub with an USB pendrive

I had a fucked up installation where only GRUB2 survived. The machine CD drive is broken and the BIOS is so old that it doesn't allow booting from USB.

  1. Install an ISO onto an USB drive using pendrivelinux.com.
  2. Insert the USB into the fucked linux and switch it on.
  3. On the grub> prompt, type ls (hd and press the tab key to auto-expand until you find the USB drive (it's most probably (hd1,msdos1)).
  4. Type set root=(hd1,msdos1).
  5. Type chainloader +1.
  6. Type boot.

An algorithm to play random music

Are you playing your huge music library in random mode for hours or days and fed up of listening the same fucking songs all over again, while never hearing others? So do I.

Regardless of what Steve Jobs and other morons think, their music players are fucked up, specially their shuffle functions. Music players running in random mode should keep the last time a song was played into account.

This is the algorithm to select which song to play next:

  1. Sort all songs by the last time they were played, in ascending order (never played ones fall at the beginning of the list, recently played songs fall at the end).
  2. Pick a given set from the beginning of the list (like, say, the 10% of them).
  3. Pick one song from this set at random.
  4. Get the author of this song and test if another song by the same author was played recently (like, say, the 10% of the last played songs). If it is, jump back to previous step.
  5. store current time as its playing time, and play it.

This way, new songs added to the set have the higher chance of being played soon, as they are at the top. Songs played a long time ago will follow. And the song that have just played won't be heard for a long time.

Implement this in your music players, scumbags.

Update: I've improved the algorithm by adding a step that spreads the authors.

HOWTO check passwords without sending them on the clear

There is a simple method to check for a valid secret among two parts without sending it on the clear. This note explains how.

  1. The server accepts a connection from the client and builds a random token (a text string). This string is sent to the client.
  2. The client concatenates the random token to the password and feeds the resulting string to a cryptographically-secure hashing function like, for example, sha1. The client sends the hash to the server.
  3. The server does the same operation (concatenating the random token to the password and hashing it) and compares the resulting hash with the one the client sent.
  4. If they match, the password is accepted and the connection goes on, otherwise is dropped.

This algorithm is related to the "salt" in UNIX passwords and to the Diffie-Hellman algorithm.

Example:

The server will only accept connections from clients that know that the password is seeKriT.

A connection is started. The server creates a random token and sends it to the client:

 OK 42d4df05

The client takes that, concatenates the password and feeds it to the sha1 hash engine:

 sha1("42d4df05seeKriT") = b0f3bd621ba92f5c26261d36a8ffb9cb3b7b399d

That monstrosity is sent to the server:

 b0f3bd621ba92f5c26261d36a8ffb9cb3b7b399d

The server then does the same concatenation + hashing:

 sha1("42d4df05seeKriT") = b0f3bd621ba92f5c26261d36a8ffb9cb3b7b399d

and tests for the result. As they are the same, it assumes the connection is valid and returns

 ACCPTD

or otherwise, if the hashes do not match, returns

 FCKYOU

and closes the connection.

Reformatting / indenting a Cascade Style Sheet file

If you need to compare two CSS files, the freestyle formatting can drive you crazy. You can use this little Perl script to reformat / reindent them. Or if you just want a tidier file.

 #!/usr/bin/perl
  1. Formats a CSS file from STDIN
  2. Angel Ortega <angel@triptico.com>
  3. Public domain
 my $css = join('', <STDIN>);
 $css =~ s/\s+/ /g;
 my $in = 0;
 foreach my $c (split(/(\s*\{\s*)|(\s*\}\s*)/, $css)) {
 	if ($c =~ /\{/) {
 		print " {\n";
 		$in = 1;
 	}
 	elsif ($c =~ /\}/) {
 		print "}\n";
 		$in = 0;
 	}
 	else {
 		if ($in) {
 			foreach my $sc (split(/\s*;\s*/, $c)) {
 				print "\t$sc;\n";
 			}
 		}
 		else {
 			print $c;
 		}
 	}
 }

I agree that, if comparing two CSS files is the aim, sorting the entries alphabetically would also be great; I left that as an exercise for the reader.
