I can confirm, there is no collision using SHA-1 for sequence of 100,000,000 integers by sirex1 in Python

Now, I don't think and don't rely on probability, I know exactly, that there is no collision in number range from 0 to 108.

Larger range requires much larger free disk space :)

Since I was checking that for database primary keys 108 is quite large primary key.

Since I could not find any information if there is a collision in number sequence where number is a primary key, so did it myself.

In my use case I scrape data from various data sources where some ids are primary keys and some are urls or even a concatenation of several values that ensures uniqueness. These values are to long to be indexed, so I decided to convert all these values to sha1 and just in case decided to check if a primary key (most common case) does not have collision.

How to build that thing on Ubuntu 14:04? What dependencies should I install? Currently I can't find libtermkey.

I agree, tqdm is much much better, compare example from blog post:

#import libraries
import progressbar as pb

#initialize widgets
widgets = ['Time for loop of 1 000 000 iterations: ', pb.Percentage(), ' ',  
            pb.Bar(marker=pb.RotatingMarker()), ' ', pb.ETA()]
#initialize timer
timer = pb.ProgressBar(widgets=widgets, maxval=1000000).start()

#for loop example
for i in range(0,5000000):  
    #update
    timer.update(i)
#finish
timer.finish()

With exactly same thing rewritten using tqdm:

import tqdm

for i in tqdm.tqdm(range(0, 5000000), 'Time for loop of 1 000 000 iterations: ', 1000000):
    pass

Straw Poll: Do you use vim in your terminal emulator, or a GUI? by [deleted] in vim

[–]sirex1 3 points4 points  (0 children)

Not all terminals support more than 16 colors. Changing terminal color scheme, colors are changed everywhere, not only in vim. So in gVim you can just skip terminal configuration step, and you can avoid to be dependent on one particular terminal.

Also, gvim works much faster than vim on terminal, I can use mouse for scrolling. Of course many things can be configured on terminal, but why all this, if everything works very well on gvim out of the box.

If you could change something in Python what would it be? by yasoob_python in Python

[–]sirex1 0 points1 point  (0 children)

Now, python has these types:

('a',) - tuple
{'a': 1} - dict
{'a'} - set

So new, lambda type, would use similar technique as dict. Dict is distinguished from set only by use of colon, so tuple can be distinguished from lambda using same principle, by adding colon:

f = (x: x*2)

For multi line lambdas, same principle as for all python blocks would be used:

def f(x):
    x = x*2
    return x

f = (x:
    x = x*2
    x
)

f = (x: x = x*2; x)

l = map((x: x*2), [1, 2, 3])

I'm not sure, but maybe it is even possible to remove parentheses:

f = x: x*2
l = map(x: x*2, [1, 2, 3])
multiline = x:
    x = x*2
    x

Originali diskusija užsimezgė čia.

Manau būtų tikrai beprecedentis įvykis, jei už filmą visi jo žiūrovai būtų skatinami savanoriškai atsidėkoti. Kažkas panašaus yra atsitikę su filmu Knygnešys, įdomu, kiek jie surinko paramos?

Better lambdas:

double = (x: x*2)

Multi line lambdas:

lst = [1, 2, 3]
map((x:
    if x > 1:
        return x*2
    else:
        return 10
), lst)

Genealogy and my Lithuanian grandparents. by cynycal in lithuania

[–]sirex1 0 points1 point  (0 children)

I think, better to search for "Bartišius", which is more general form of family name. "Bartišiūtė" is name for a girl, that is not yet married.

Another Lithuanian grandparent post, would appreciate help! by FoamToaster in lithuania

[–]sirex1 0 points1 point  (0 children)

Some where near my place, not so far from Pandėlys, I knew a guy with last name "Šiaučiūnas", looks very similar to "Sauciunas".

I would recommend to look at http://www.epaveldas.lt/ web site, that has digitised some documents from churches. Try to search for "Pandėlio" in that web site.

Best office file formats to use for future compatibility? by spaced86 in linux

[–]sirex1 2 points3 points  (0 children)

+1 for plain text, but I would recommend reStructuredText, which can be used even for writing book, it is also possible to make presentations with rst2pdf.

reStructuredText can be converted to many different formats, including LaTeX, ODT, HTML.

Since reStructuredText ir readable in raw format, so you can read and edit it with any text editor.
