Emacs - Buffer is read-only: #

Si tenemos permiso de escritura a un archivo, pero no tenemos permiso de escritura en el directorio donde reside este, es decir no podemos crear el archivo temporal en el directorio donde esta ubicado el archivo que queremos modificar. Emacs nos da el error como Buffer is read-only o write protected

Para eso podemos apuntar los archivos de backup y los de guardado automático a una dirección distinta que en la que esta ubicado el archivo a editar. Para esto editamos el archivo .emacs en nuestro HOME y agregamos la siguiente indicación

;; apuntar los archivos de backup
(setq backup-directory-alist
`((".*" . ,temporary-file-directory)))

;; apuntar los archivos que se guardan automaticamente
(setq auto-save-file-name-transforms
`((".*" ,temporary-file-directory t)))

Stats

This page can appear if you have not enabled statistics. To enable statistics, log into your Moodle as an administrator. Then, in the Site Administration menu, under Server --> Statistics ensure that they are enabled.

If you have enabled Statistics recently you should note that statistics are collected by a background task and take some time to become available. Try again later, but do note the time for statistics job to be run in the Site Administration page noted above.

Statistics
From MoodleDocs
Jump to: navigation, search

Location: Administration > Server > Statistics


If you enable site statistics, Moodle will gather statistics about each course and for the whole site, and produce graphs displaying them.

The statistics graphs and tables show how many hits there have been on various parts of your site during various time frames. They do not show how many distinct users there have been. They are processed daily at a time you specify. You must enable statistics before you will see anything.
Enabling site statistics

1. Access Administration > Server > Statistics (or Site Administration > Advanced features in 2.0 onwards).
2. Tick the "Enable statistics" checkbox.
3. As stats processing is quite resource intensive, it is recommended that you should set the stats processing to start in the early morning.
4. Click the "Save changes" button.

TIP: Set the stats processing to start an hour before your automated course backups are scheduled to start, then set the maximum runtime to 1 hour. This ensures that stats are not being processed at the same time as course backups are being made.

Statistics not working?

If statistics isn't working and you have checked all the obvious (such as whether it's enabled), check Administration > Modules for any old hidden modules in the database which miss the files in the moodle/mod folder on your server. If you find any, they should be deleted.

You can also try limiting the length of time logs are kept for to reduce the size of the tables. Go to Administration > Server > Cleanup to set this.

To run stats manually, go to the database, go to the mdl_config table and set statslastdaily, statslastweekly and statslastmonthly to 0 (leave statslastmonthly alone if you think it might be large logtables causing the problem). Then go to Administration > Server > Statistics and set statsruntimestarthour to 5 mins ago. Then visit http://www.yoursite.com/admin/cron.php. You should see output there saying that stats are processing, but be patient if it appears to hang - this can take between 5 mins and several hours depending on how big your site is, so just leave it going.

Moodle - Depurar errores

Usando moodle 1.9.3 (Build: 20081015)

Para poder ver los mensajes de error que moodle muestra hay que entrar como administrador.

Dentro del panel de Administración del Sitio seleccionar Servidor / Depurando

En "Depurar mensajes" (debug) Seleccionar "DESARROLLADOR: mensajes extra de depuración Moodle para desarrolladores".


Documentación sobre el tema en:

http://docs.moodle.org/en/Debugging#How_to_turn_on_debugging

How to turn on debugging

Go into the admin screens, and look under Administration > Server > Debugging (In Moodle 2.0 it is Site administration ▶ Development ▶ Debugging). Set the...

* Debug messages to ALL, and
* Display debug messages to Yes.

(You must do both). There is rarely any advantage in going to Developer level, unless you are a developer, in which case it is strongly recommended.

Once you have got the error message, and copied and pasted it somewhere, you are recommended to turn debugging back off again.
