This constant keeps track of the MBR Total Size.

This size is calculated like so:

These values are derived from:

446 bytes - Bootstrap size.
 64 bytes - Partition table size.
  2 bytes - Signature size.

On the www there is also the 446 commonly used with “dd”. You can use 446 bytes to overwrite or restore your /dev/XYZ MBR boot code only with the contents of $mbr.backup.file.

You can use 512 bytes to overwrite or restore your /dev/XYZ the full MBR (which contains both boot code and the drive’s partition table) with the contents of $mbr.backup.file.

#

Roebe.date_sort_based_on_filename

This method will sort an array of filenames, based on the date that these files have. By default we will top-sort the most recent file, so oldest files will be shown last.

So if we have “22.05.2023-foobar1.mp4” and “22.03.2011-foobar2.mp4” then this method will return a sorted Array where foobar1.mp4 will appear as first element, and foobar2.mp4 will appear as the last element.

This method was added in May 2023. The reason was that I noticed that in different of my gems I needed this functionality, so it made sense to put the code into one toplevel method that other projects could re-use, as-is.

Invocation examples:

Roebe.date_sort_based_on_filename(%w( 11.01.2021-foobar3.mp4 22.05.2023-foobar1.mp4 22.03.2011-foobar2.mp4 ))

.enter_chroot(which_variant = :depot_chroot, chroot_target = '/Depot/Chroot/', use_this_path_for_env = '/usr/bin/env') ⇒ Object

#

Roebe.enter_chroot

This method can be used to enter a chroot environment.

I am not sure whether this is possible from ruby - but at the least the shell-syntax can be shown on the commandline, which is one use case for this method here.

.generate_konsole_css_file(save_into_this_file = 'konsole.css', use_this_colour = :skyblue) ⇒ Object

#

Roebe.generate_konsole_css_file

The second argument specifies which colour is to be used for the active tab.

To invoke this method from the commandline, do:

roebe --generate-konsole-css-file

Then you can load this into KDE konsole. Go to:

Settings -> Configure Konsole -> TabBar
Specify the path to this css file, then activate the checkbox
and click on "Apply".

Most html-colours appear to work - at the least skyblue and others.

#

Roebe.install_roebe_addons

This method here will install some of my addons, from a remote website.

This helps me setup a “workstation” on a linux environment that happens to have ruby. It MUST also work when openssl is not available - using “gem install name” is not an option because this depends on openssl itself.

We will use a very naive approach here - we will simply install from shevegen.square7.ch, where the respective gems are assumed to reside. For this to work, the remote URLs obviously must have the specific gem.

We could just use the main array right? Hmm. Anything against this?

.prettify_url(i = :installation, shall_we_replace_the_localhost = :default) ⇒ Object

#

Roebe.prettify_url

This will delegate towards class BeautifulUrl, since as of July 2011.

This method is to be used consistently whenever we seek a “correct” URL that has been pre-registered in the BeautifulUrl namespace.

We purposely do not make use of Arrays, because we want to return something.

Usage example:

Roebe.prettify_url(:installation) # => "/home/x/DATA/PROGRAMMING_LANGUAGES/RUBY/src/rbt/lib/rbt/yaml/installation_procedere.yml"

It will return a String.

@return [String]

This method was changed in February 2022, aka renamed from “run” to “run_shell”, as it conflicted with “class Roebe::Run”. This was announced to be a possibility for a rename-operation back in September 2020, so it should not have come as a surprise.

.run_this_sinatra_app(i = 1) ⇒ Object

#

Roebe.run_this_sinatra_app

This method can be used to “lazily” start a sinatra-app from one of the roebe/www/ .sinatra files.

Currently (April 2022) this method is limited to require numbers as input, but in the future we may also make use of BeautifulUrl to find the appropriate .sinatra file instead.

Usage examples:

Roebe.run_this_sinatra_app(1)
Roebe.sinatra(2)

.set_alias(number, to = '') ⇒ Object

#

Roebe.set_alias

This method is a bit different than the other ones above, as it is generic.

How to use this method?

Simply pass, as the first argument to this method, the number that you seek to change, such as 6.

As second argument to this method, just like the methods defined above, you can assign the text that is to be used for that number.

Note that this method will begin to count at 1 rather than 0.

Specific usage example for this:

Roebe.set_alias(3, 'foobar')

#

Roebe.set_background (background tag)

Use this to change or set a new background. Ideally, it should work on different WMs/DEs and also on Windows.

This method accepts one (optional) argument.

If you wish to have a completely black background, do this:

setbg BLACK

The important options for fbsetbg are:

-f  Set fullscreen wallpaper (this is the default)
-c  Set centered wallpaper

.to_movie(i = @_, store_here = '/Depot/Video/output_images.avi') ⇒ Object

#

Roebe.to_movie

Use this method to create a little movie from different image files, by making use of mencoder.

We will use the current directory as input.

More information about this can be obtained from here:

.to_mp3(i = ARGV) ⇒ Object

#

Roebe.to_mp3

Method to convert an audio file to a .mp3 file, e. g. a .wav file into a .mp3 file.

Keep in mind that lame can not convert all .wav files. For example, Microsoft’s “ADPCM codec” can not be converted by lame. Lame may output the error message “Unsupported data format: 0x0011”, so use ffmpeg instead. Ffmpeg has no problem with that codec.

.trad(i = ARGV) ⇒ Object

#

Roebe.trad

The input is downcased because otherwise downstream errors may occur, e. g. Liblzma versus liblzma, whereas only lzma is registered.

Since as of 26.08.2022 the old code in this class has been deprecated and removed. RBT itself offers this functionality now, via class RBT::CompileInTraditionalManner.

end

.traditional_fibonacci(i = 1) ⇒ Object

#

Roebe.traditional_fibonacci

The fibonacci sequence starts with 1.

The previous two numbers will determine the next value to be used.

Examples:

1 + 1 =  2 (This is our 3rd value)
1 + 2 =  3 (4th)
2 + 3 =  5 (5th)
3 + 5 =  8 (6th)
5 + 8 = 13 (7th)

This method is also called the “traditional Fibonacci” implementation. It is very slow the larger the input-number will be, thus it is not really too terribly useful.

.traurige_oder_fröhliche_zahl(i) ⇒ Object

#

Roebe.traurige_oder_fröhliche_zahl

Es handelt sich dann um eine fröhliche Zahl, wenn folgende Rechenvorschrift mit einer endlichen Anzahl an Iterationsschritten zur Zahl 1 führt:

(1) Es wird jede Ziffer der gegebenen Zahl quadriert.
(2) Die Quadrate werden summiert.

Auf die Summe wird wieder diese Rechenvorschrift ausgeführt. Wird eben die Zahl 1 erreicht, dann ist die Berechnung am Ende angekommen.

Folgende Beispiele repräsentieren fröhliche Zahlen:

23 → 2 2 + 3 2 = 13 → 1 2 + 3 2 = 10 → 1 2 + 0 2 = 1
97 → 9 2 + 7 2 = 130 → 1 2 + 3 2 + 0 2 = 10 → 1 2 + 0 2 = 1
 7 → 7 2 = 49 → 4 2 + 9 2 = 97 → 9 2 + 7 2 = 130 → 1 2 + 3 2 + 0 2 = 10 → 1 2 + 0 2 = 1

.try_to_extract_this_gem(i) ⇒ Object

#

Roebe.try_to_extract_this_gem

Use this method if you wish to extract a ruby .gem archive. Normally you could - and should - use the “gem” utility for this, but sometimes, for various reasons, you may have to use a non-gem based method to extract .gem files. This is why this method exists.

Presently (past July 2017), we will make use of “tar” to extract a .gem file but this may change at a later time, perhaps even using a ruby-internal way instead.

.update(install_how = :both) ⇒ Object

#

Roebe.update (iruby tag, update tag)

Purpose of this little method is to update my personal ruby projects, no matter what. We will also dump into the directory /Depot/Temp/MyGems (My custom addons)

Since as of Feb 2015 we will also put these .gem files into an archive directory.

The first argument ‘install_how` can be either of these 3 values:

:gem or :setup or :both

To invoke this method from the commandline, do:

rupdate

.update_pciids(i = :ruby_way, remote_url_to_use = 'http://pci-ids.ucw.cz/v2.2/pci.ids') ⇒ Object

#

Roebe.update_pciids

There are two ways how to use this method:

(a) the :ruby_way
(b) the :pciutils_way

The default is the ruby way; the variant with pciutils exists primarily so that we can remain compatible with the shell script called update-pciids, which comes from the “pciutils” suite.

This method can also be called from the commandline, by issuing a command like:

roebe --update-pciids
