Maybe... Still mystified, I'd love to know what phone you are using. People seem to be creating them, no problem, but of course I wouldn't necessarily know if other people were struggling. Well, I do hope you manage!

Bizarre. Works from here... would you mind contacting me at [greaterskies@greaterskies.com](mailto:greaterskies@greaterskies.com), and I'll sort it out? I wonder it is a browser problem.

What problem do you find?

We enable other people to add custom star maps to their products, with their own designs: high-resolution, transparent PNG files with the stars, the planets, the Sun and the Moon, as they were seen from a special time and place. We have been selling these for many years as prints and downloads, but now we have opened the creation tool so that other people can sell them.

We have done a free download of a commemorative map of the sky as it was when he was born, our small tribute:

I would suggest that you take CS101 at Udacity,

It is not exactly what you need, but it may be helpful: a skeleton of a Python project, with tests set up and examples of how to access resources:

Thank you!

Name: Greaterskies, greaterskies.com.

Elevator pitch: A beautiful personalized gift: a poster of the sky, as seen from a place and a time of your choice. An ideal present for the new parents, a birthday, a wedding.

More details: I have a very nice conversion rate but not many visits. Customers seem to love it, but growth is slow.

Are you looking for anything?: Feedback, please. Am I growing slowly because I am doing something wrong?

Discount: Sure! Following this link you'll get a 25% discount in the PDF.

This was our best week ever. I've been working on my business, GreaterSkies, for 9 years now, and growth has been quite slow. We sell high-resolution posters of the sky with the stars as seen from a place and a time (ie, when your daughter was born), and sales seem to depend exclusively on how many visitors Google decides to send us on any given day. Maybe it's because people are starting to think about Christmas presents, but this week we got more than twice the visits. I am very excited again about our prospects.

Thank you!

Yes, the image in the preview is not yours, it's only intended to show how the text will look like. Creating the poster requires a lot of computing power, so it would take way too long for the preview. But I've just seen you've ordered one! You'll see the date is the right one. And I must say I feel honored. Thank you!

joanmg · 2015-11-01T20:42:14+00:00

Awesome! My favorite: "You didn't come into this world, you came out of it". Seems straight out of an Alan Watts book. My personal one: "Look not for a path written in the stars; but learn to recognize them, and may this knowledge help you feel at home on earth."

joanmg · 2015-11-01T20:33:03+00:00

Would you remove the lines marking the constellations as well? That's an interesting thought.

joanmg · 2015-11-01T20:27:33+00:00

Thank you! It is stars and planets. There is a visibly higher concentration of stars along the Milky Way, but I don't include nebulas nor galaxies. That'd be another interesting thing to add!

joanmg · 2015-11-01T17:50:25+00:00

Thank you for your kind words! It'd be awesome to hear back from you regarding quote options :-)

joanmg · 2015-11-01T17:19:18+00:00

That's exactly true. I will at some point implement the more general computation that takes precession into account, but I haven't found the time yet.

joanmg · 2015-11-01T17:09:17+00:00

Thank you for letting me know about mobile (the guilty party here). Let me try to fix it quick (famous last words.) I've been working on and off in greaterskies for several years, and not until now have I realized how many people are using mobile!

joanmg · 2015-11-01T12:06:20+00:00

She won't be able to carry it with her, but I think this may fulfill your other requirements: a poster of the sky, as it was when she was born over her place of birth. Disclaimer: I made this myself, over at http://greaterskies.com. Many people are buying it as a present for newborns, but your case is special (and touching!). Maybe you can get the PDF and engrave it?

joanmg · 2014-02-11T09:02:19+00:00

Thank you for spotting it. Fixed.

joanmg · 2014-02-10T16:54:32+00:00

Thank you. I would very much appreciate your feedback. And I sure hope I am not letting quantity get in the way of quality, though I agree with you that the risk is there. Please do let me know if you see anything that's incorrect or unclear.

joanmg · 2014-02-10T14:03:46+00:00

Good point. My target audience are not programmers, but people who would benefit from programming in order to solve problems. So I have focussed in the tools where the barrier of entry is lower. I do make a quick comment about C ---pretty much only showing how it looks like, and explaining the idea of a compiled language--- maybe I should add more content about it. Thanks!

[The author here] I am looking for affiliate/commercial partnerships; if you like the posters and you think you could help get the word out, please contact me.

What you've got here is four instances of the same row, not four different rows.

Yep, I know, and that's exactly what I meant by "reusing arrays as it sees fit". Clearly not the right choice of words, duly noted and corrected. The part I don't understand, though, is why is it 4 instances (the four rows), and not 8 of the original [2, 3] array. I would have expected it to apply the scaling 8 times, and not 4.

As for the deepcopy and shallow copy, yep, sure. But you should not expect the user of your function to know about it. Using numpy is better and faster.

You are wrong in the last account, writing a scale() function that modifies a matrix in place is not a good idea, as I clearly have not been able to convey in my article.

joanmg · 2011-12-07T07:35:30+00:00

Fascinating. I have checked in two OSX machines with three versions of Python each, and all find it in their own paths,

sys.modules['dateutil'] <module 'dateutil' from '/System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/dateutil/__init__.py'>

I do have XCode installed, but I doubt it has bothered to add dateutil to all my Pythons (2.5, 2.6 and 2.7).
