Introducing Aranduka

Yes, it's yet an­oth­er pro­gram I am work­ing on. But hey, the last few I start­ed are ac­tu­al­ly pret­ty func­tion­al al­ready!

And... I am not do­ing this one alone, which should make it more fun.

It's an eBook (or just any book?) man­ager, that helps you keep your PDF/­Mo­bi/F­B2/what­ev­er or­ga­nized, and should even­tu­al­ly sync them to the de­vice you want to use to read them.

What works now? See the video!

In case that makes no sense to you:

  • You can get books from Feed­­Book­s. Those books will get down­load­­ed, added to your database, tagged, the cov­­er fetched, etc. etc.

  • You can im­­port your cur­rent fold­er of books in bulk.

    Aran­­du­­ka will use google and oth­­er sources to try to guess (from the file­­name) what book that is and fill in the ex­­tra da­­ta about it.

  • You can "guess" the ex­­tra da­­ta.

    By mark­ing cer­­tain da­­ta (say, the ti­tle) as re­li­able, Aran­­du­­ka will try to find some pos­si­ble books that match then you can choose if it's right.

    Of course you can al­­so ed­it that da­­ta man­u­al­­ly.

And that's about it. Planned fea­tures:

  • Way too many to list.

The goals are clear:

  • It should be beau­ti­­ful (I know it is­n't!)

  • It should be pow­er­­ful (not yet!)

  • It should be bet­ter than the "com­pe­ti­­tion"

If those three goals are not achieved, it's fail­ure. It may be a fun fail­ure, but it would still be a fail­ure.

Very pythonic progress dialogs.

Sometimes, you see a piece of code and it just feels right. Here's an example I found when doing my "Import Antigravity" session for PyDay Buenos Aires: the progressbar module.

Here's an example that will teach you enough to use progressbar effectively:

progress = ProgressBar()
for i in progress(range(80)):
    time.sleep(0.01)

Yes, that's it, you will get a nice ASCII progress bar that goes across the ter­mi­nal, sup­ports re­siz­ing and moves as you it­er­ate from 0 to 79.

The progressbar module even lets you do fancier things like ETA or fie transfer speeds, all just as nicely.

Is­n't that code just right? You want a progress bar for that loop? Wrap it and you have one! And of course since I am a PyQt pro­gram­mer, how could I make PyQt have some­thing as right as that?

Here'show the out­put looks like:

progress

You can do this with ev­ery toolk­it, and you prob­a­bly should!. It has one ex­tra fea­ture: you can in­ter­rupt the it­er­a­tion. Here's the (short) code:

# -*- coding: utf-8 -*-
import sys, time
from PyQt4 import QtCore, QtGui

def progress(data, *args):
    it=iter(data)
    widget = QtGui.QProgressDialog(*args+(0,it.__length_hint__()))
    c=0
    for v in it:
        QtCore.QCoreApplication.instance().processEvents()
        if widget.wasCanceled():
            raise StopIteration
        c+=1
        widget.setValue(c)
        yield(v)

if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)

    # Do something slow
    for x in progress(xrange(50),"Show Progress", "Stop the madness!"):
        time.sleep(.2)

Have fun!

For the Win

Review:

A re­al page turn­er. Tak­ing ad­van­tage of it be­ing CC, I think I may at­tempt trans­lat­ing it to span­ish (ar­gen­tini­an flavour)

The first english Issue of PET (our Python Magazine) is out!

Hell yeah! It has been a lot of work but it's out at http://re­vista.python.org.ar

Some ar­ti­cles:

  • PyAr, The His­­to­ry

  • from gc im­­port com­­mon­sense - Fin­ish Him!

  • Pain­­less Con­cur­ren­­cy: The mul­ti­pro­cess­ing Mod­­ule

  • In­­tro­­duc­­tion to Unit Test­ing with Python

  • Taint Mode in Python

  • Ap­­plied Dy­­namism

  • Dec­o­rat­ing code (Part 1)

  • We­b2Py for Ev­ery­­body

It's avail­able in pret­ty much ev­ery for­mat any­one can read, and if your favourite is not there, we will make it for you or may I be smote by the fly­ing spaghet­ti mon­ster's nood­ly ap­pendage!

AFAIK there is no oth­er Python mag­a­zine be­ing pub­lished (feel free to cor­rect me), so it's kind of a big thing for us in PyAr (the Ar­genti­na Python com­mu­ni­ty) that we are do­ing one, and in two lan­guages.

But why stop here? Want it to be avail­able in your lan­guage? Con­tact us at re­vistap­yar@net­man­ager­s.­com.ar it may be doable!

And of course, very soon there will be a call for ar­ti­cles for Is­sue 2, and trust me: that one's go­ing to be epic: this one was just a warmup.

Review:

Some things were fun, but it's not my cup of tea.
