Kiwi PyCon, DjangoCon US, and PyCodeConf Recap

I just got back from a long conference circuit, attending and speaking at PyCon Australia, Kiwi PyCon, DjangoCon US, and PyCodeConf.  It was a ton of work, but it was a blast.

I got to blog about PyCon Australia already, but then the time in between the other conferences was just a bit too hectic to blog.  

Kiwi PyCon 2011

I gave the opening keynote speech at Kiwi PyCon in Wellington, New Zealand. The talk was meant to be mildly provocative but in an inspiring, “go out and code” kind of way.

The Pythonistas of New Zealand are amazing. I met more Twisted devs than I’ve ever met in my life, attended tons of hardcore Python talks by women, and ones by men too, and learned all sorts of new things. I was also blown away by the hospitality of the conference organizers, particularly Tim McNamara and Richard Shea.

After the conference, I spent a couple of days going around the countryside and southern island coastal towns with Danny. It was spectacular.

DjangoCon US 2011

I co-presented the Django Package Thunderdome with Daniel Greenfeld. Here we presented the results of a survey of the most recommended third-party packages of the Django world.

I got to attend with several of the LA PyLadies as well as others whom I knew online through IRC #pyladies and the PyLadies Sponsorship Program. Hanging out in the unofficial PyLadies welcome suite was more fun than should be allowed :)

The DjangoCon US organizers (Sean O’Connor and Steve Holden) let us get away with tons of things, including selling “Djangsta” shirts to benefit PyLadies and setting up a PyLadies welcome table beside the registration desk.

PyCodeConf 2011

I attended and spoke at the first ever PyCodeConf, a new kind of Python conference with a radically different format. Speakers are invited to speak about whatever they desire relating to the theme (“The Future of Python”), in front of a room of round tables. In between talks there are long breaks to encourage discussion. As a result, talks are edgier, and you really get to know people and possibly shape the future together.

I gave a talk about how third-party package ecosystems either form and flourish or don’t form, depending on various factors. I brought up packaging patterns and anti-patterns seen in the Python package ecosystem as well as those of other languages.

This was a conference with a superstar lineup, including many notable woman speakers whom the organizers went out of their way to invite.  It was very thoughtfully planned by the organizers of CodeConf and JSConf (Tom Preston-Werner, Chris Wanstrath, and Chris Williams), and the attention to detail really showed.  

The informal chats and bonding during the after-hours parties made this conference especially worthwhile. There’s something special about talking to other developers while you’re in a 14th floor swimming pool.

Summary

Overall it was thrilling to get my thoughts out there and try to inspire people all over the world. It was also quite nerve-wracking and stressful, but I’m glad I did it.

I learned tons and am already applying much of that knowledge directly to projects at work at Cartwheel Web.  If your employer doesn’t already send you to Python conferences, you should ask to be sent.  You come back with experiences, connections, and knowledge that are priceless.

Thank you, PyCon AU

I managed to squeeze my personal Python wishlist into this keynote speech about diversity in Python.  

More image processing options besides what we have in PIL 1.1.7, please.  More attempts at Python in the browser. More Python packages in general.  More diversity of Python packages.  More diverse Python open-source package authors from all walks of life.  

“There should be one — and preferably only one — obvious way to do it” is about the design of Python as a language, not about artifically limiting the diversity of packages.  Let’s tap as many untapped resources as possible and try to grow the Python package ecosphere.

PyCon Australia was beyond amazing.  There is something special about the atmosphere there, a feeling of openness that promotes open discussion.  There was a talk by Richard Jones evaluating/comparing Python microframeworks, and a talk by Graham Dumpleton comparing web hosting mechanisms, including comparisons of web servers.  It was great to see these types of comparison/overview talks, and I think the friendly audience was what made presenting such topics possible.

I got to host the “Women in Python” breakfast and meet many of the thirty-five women who attended the conference.

Also, I was thrilled to see several female speakers presenting interesting Python talks: Brianna Laugher giving a talk on Zookeeper (Pylons-based conference management software powering linux.conf.au), Georgina Wilcox and Katie M. Bell giving a talk about teaching Python, and of course Mary Gardiner of the Ada Initiative giving a keynote speech about Python open-source projects (Plover, Software Carpentry, Calibre, Sugar).  

Finally, it was great to talk to Elena Williams who was inspired to get started on organizing DjangoCon AU and co-organizing PyLadies groups in Australia with Jenny Nguyen and Kathleen O’Toole.  Also, I hear that Brianna Laugher and Rhydwyn are planning to teach a women’s Python workshop in Melbourne, possibly with Melbourne PUG.  And Elena and Jenny may be starting Python user groups at their universities.  It’s very exciting.

How to create Sphinx docs the Python / Github / Read the Docs way

This is a full walkthrough of how to document a Python package, using https://github.com/audreyr/django-startcbv as the sample package to be documented.  It probably works for non-Python packages too.
Follow along with documenting a Python package of your own.  Or try it with one of those poor, undocumented, lonely Python packages out there!

At the command line:
</div><div>pip install Sphinx==1.0.7 (or whatever the latest version is)</div><div>mkdir docs</div><div>cd docs</div><div>sphinx-quickstart</div> <div><div><meta http-equiv="content-type" content="text/html; charset=utf-8">

Enter something like the following at the prompts:
</div> <div>> Root path for the documentation [.]: </div></div><div><div>> Separate source and build directories (y/N) [n]: </div></div><div>> Name prefix for templates and static dir [_]: </div><div><div>> Project name: django-startcbv</div> <div>> Author name(s): Audrey Roy</div></div><div><div>> Project version: 0.1</div><div>> Project release [0.1]: </div></div><div><div>> Source file suffix [.rst]:</div></div><div><div>> Name of your master document (without suffix) [index]: </div> </div><div><div>> autodoc: automatically insert docstrings from modules (y/N) [n]: y</div><div>> doctest: automatically test code snippets in doctest blocks (y/N) [n]: </div><div>> intersphinx: link between Sphinx documentation of different projects (y/N) [n]: </div> <div>> todo: write "todo" entries that can be shown or hidden on build (y/N) [n]: </div><div>> coverage: checks for documentation coverage (y/N) [n]: </div><div>> pngmath: include math, rendered as PNG images (y/N) [n]: </div> <div>> jsmath: include math, rendered in the browser by JSMath (y/N) [n]: </div><div>> ifconfig: conditional inclusion of content based on config values (y/N) [n]: </div><div>> viewcode: include links to the source code of documented Python objects (y/N) [n]: y</div> </div><div><div>> Create Makefile? (Y/n) [y]: </div><div>> Create Windows command file? (Y/n) [y]: </div></div><div><meta http-equiv="content-type" content="text/html; charset=utf-8">

At the command line:
</div><div>make html</div><div><meta http-equiv="content-type" content="text/html; charset=utf-8">

Add to docs/conf.py:
</div><div><div>sys.path.insert(0, os.path.abspath('../startcbv'))</div><div>sys.path.insert(0, os.path.abspath('../test_project'))</div> <div> </div><div>import settings</div><div>from django.core.management import setup_environ</div><div>setup_environ(settings)</div></div><div>

Add to your .gitignore file:
</div><div>_templates</div><div>_static</div><div>_build</div></div><div><meta http-equiv="content-type" content="text/html; charset=utf-8">

Create docs/ref_startcbv.rst:
</div><div>==========================</div><div>Reference for startcbv app</div> <div>==========================</div><div> </div><div>The startcbv app gives you the management command "python manage.py startcbv things".</div><div> </div><div> </div><div>``startcbv management command``</div> <div>===============================</div><div>.. automodule:: management.commands.startcbv</div><div>    :members:</div><div>    :undoc-members:</div></div><div><meta http-equiv="content-type" content="text/html; charset=utf-8">

Copy and paste your installation and usage instructions from README.rst into docs/installation.rst and docs/usage.rst.  I know it’s annoying.  There’s no good way to symlink your Github readme content to your Read the Docs Sphinx readme content (yet). 
Add to docs/index.rst so that it looks something like:

</div><div><div><div>.. django-startcbv documentation master file, created by</div><div>   sphinx-quickstart on Mon Jul 11 21:34:47 2011.</div> <div>   You can adapt this file completely to your liking, but it should at least</div><div>   contain the root `toctree` directive.</div><div> </div><div>Welcome to django-startcbv's documentation!</div><div>===========================================</div> <div> </div><div>Contents</div><div>-----------</div><div> </div><div>.. toctree::</div><div>   :maxdepth: 2</div><div>   </div><div>   installation</div><div>   usage</div><div>   </div><div>API/Reference Docs</div> <div>--------------------</div><div> </div><div>.. toctree::</div><div>   :maxdepth: 2</div><div> </div><div>   ref_startcbv</div><div> </div><div>Indices and tables</div><div>==================</div><div> </div> <div>* :ref:`genindex`</div><div>* :ref:`modindex`</div><div>* :ref:`search`</div></div></div><div>
Commit and push it all to Github:

</div><div>cd ~/code/django-startcbv</div> <div>git add .</div><div>git commit -m "Added Sphinx docs."</div><div>git push</div><div>
Go to readthedocs.com and create an account.  
Enter something like the following:

</div><div>Name: django-startcbv</div> <div>Repo: http://github.com/audreyr/django-startcbv.git</div><div>Repo type: Git</div><div>Description: Management command to start an app with class-based views.  You use "python manage.py startcbv ".  It's very fresh and unstable, so use at your own risk, but it does work!
Project URL: https://github.com/audreyr/django-startcbv</div><div>Tags: ”class-based views”, Django, management</div><div>Default branch: (blank)</div> <div>Use virtualenv: (unchecked)</div><div>Requirements file: (blank)</div><div>Documentation type: Sphinx HTML</div><div>
Click Submit.

Now go to your project on Github (something like https://github.com/audreyr/django-startcbv) and click Admin > Service Hooks > ReadTheDocs.  Scroll up.  Check “Active”.  Click “Update Settings”.  From now on, whenever you do a “git push”, your readthedocs.com / rtfd.org docs will be auto-updated.
That’s it.  You’re done.

Note: you may have also heard of hosting your docs on http://packages.python.org/.  It’s another place to host docs but requires manual updating by the PyPI staff.  Personally, I like using ReadTheDocs instead, though, because:
  • the Github hooks keep my docs up-to-date without manual intervention.  Whenever I update my .rst files, I don’t have to re-upload my docs!
  • the docs are easier to find via search engines
Also, whatever you do, don’t use a wiki or a blog post for your package’s official docs.  Informally taking notes on your blog like this is fine, but if you’re writing up docs for your Python package, take the extra step of copying and pasting the text into ReStructuredText files and generating Sphinx docs.  Why? People will be more likely to use your package, and your users will all thank you for your diligent documentation efforts.
Finally, whenever you do something complicated without documenting it, imagine the documentation donkey (a cross between the Django pony and the Shrek donkey) kicking you the next time you can’t figure out how to retrace your steps.

Call to Action: PyLadies Seattle + Sydney, AU + Wellington, NZ

PyLadies is a worldwide community of ladies and supporting gentlemen who use the Python programming language.
We are currently putting together an open-source PyLadies kit.  I hope it’ll help Pythonistas in various cities start their own local chapters.  There’s not much in there yet, but there will be.  We’ll be putting the contents up on Read the Docs (rtfd.org) shortly.
https://github.com/pyladies/pyladies-kit

I would like to help interested Python developers (hey women & men, I’m talking to you!) start PyLadies chapters in other cities, starting with inaugural PyLadies meetups on these dates.  Email me at audreyr@pyladies.com if you will be available, and suggest a few good times:
Seattle PyLadies
July 7 or 10, 2011

Sydney, Australia PyLadies
August 19 or 24, 2011
Wellington, New Zealand PyLadies
August 29, 2011

How this works:  This is a meetup for beginner through advanced Python developers who are interested in gender diversity.  It is not a workshop.  We’ll get together somewhere, ideally at a local Python company willing to step forward and host the event.  (I’ll thank you with all my heart for helping improve diversity in the Python world if your company hosts.)
I’ll walk you through the kit and help you build a PyLadies chapter in your city.  I have some important tips and tricks to make it happen, including:
  • Get as many ladies as possible from the first 2 or so meetups to commit to being co-organizers.  The more people feel personally invested in the group from the start, the better.  2-10 is a good number.
  • If you’re a gentleman, encourage the ladies to both lead and take credit.  Step back and take a supporting volunteer role.  Empower them by letting them become known leaders.  
We’ll go around the room with introductions, telling each other a bit about what we all do.  

When we’re done talking and planning, we’ll go out for drinks to celebrate and start building friendships with other locals who care about diversity in Python.  
There’s something magical about being in a room of female Python developers, or even just being a man in a room of Python developers where 60% are experienced female devs.  As your chapter grows, you’ll see “Diversity as a Dependency” (as Anna Martelli Ravenscroft puts it) begin to happen in real life.

D+A

I met the amazing Danny Greenfeld last year and fell madly in love.  

Here we were tangoing at PyCon 2010.

2010-02-20 23.21.30

Here we are in front of the Lawrence Journal-World headquarters in Lawrence, KS, birthplace of the Django web framework. We love Lawrence!

Me and Audrey in front of Django's birthplace

Here he was doing djymnastics around me at Djangocon 2010.  (Thanks, Shawn Rider, for making this awesome video.)

Here we were at PyCon 2011 leading the Packaginator sprint together. Danny’s on the left, cut off a bit by the camera, but you can see the smile on our faces.  If you zoom in and look closely, you can see that Danny’s arm is around me.

Packaginator sprinters!

We wouldn’t have found each other if not for the following things and people:

  • The PyCon 2010 diversity grant.  If not for this, I would have been shy to attend PyCon.  I applied for the grant on a whim.  When I got it, I was terrified of going and not knowing anyone, but I knew I had to go.
  • Gloria W. Jacobs, whom I shared a room with at PyCon and who encouraged me to go out and meet some of the amazing people at PyCon.
  • James Bennett and his Django tutorial at PyCon 2010, where Danny and I met for the first time.
  • Barbara Shaurette, whom I recognized from following her blog/Twitter and recognizing her bright red hair from her avatar.  She introduced me to Danny and is the real main reason we met, actually!  She was super nice when I asked to see her Django pony tattoo.
  • Jennifer Leech and her impromptu PyCon 2010 tango BOF hallway track that Saturday night.  Before then, I had shaken Danny’s hand but had never embraced him.  Chris Adams and Tom Brander taking photos of us at this, which turned out to be our very first date.
  • Steve Holden and his PyCon 2010 party.
  • Katie Cunningham and Chris Adams encouraging us to be together at the party.
  • Zed Shaw for teaching us Argentine tango after he heard that we liked tango, and teaching me how to do a Judo hip throw simultaneously so that I could throw him happily.
  • Honza Kral for teaching Danny how to dip me properly.
  • James Tauber, Brian Rosner, the Pinax framework and the PyCon 2010 Pinax sprint.

Getting outgoing email to work in Django and Pinax

Django and Pinax steps(I’ve got Django 1.2, Pinax 0.9a1)

First, install postfix (an SMTP server) on your VPS (in my case, a Linode node or Rackspace Cloud server).
sudo apt-get install postfix Enter “yourdomain.com” when it asks you for it.  There, now you have your own SMTP server.

Add something like this to your settings.py so that outgoing mail comes from postfix.
DEFAULT_FROM_EMAIL = ‘Your Site <yourdomain-noreply@yourdomain.com>’
EMAIL_BACKEND = ‘django.core.mail.backends.smtp.EmailBackend’
EMAIL_USE_TLS = True
EMAIL_HOST = ‘localhost’
EMAIL_HOST_USER = ‘yourdomain-noreply@yourdomain.com’
EMAIL_HOST_PASSWORD = ”
EMAIL_PORT = 25
EMAIL_SUBJECT_PREFIX = ‘[Your Site] ’ If your site uses Django but not Pinax, you’re done.  To test it, restart Apache or touch your wsgi file, then enter the following 2 lines in a “python manage.py shell” (I hope you’re in your virtualenv) at the prompt:
from django.core.mail import send_mail
send_mail(‘Subject here’, ‘Here is the message.’, ‘from@example.com’, [‘to@example.com’], fail_silently=False)
…and if you got an email in your “to@example.com” account, you’re all set.  

Additional Pinax steps
If your site uses Pinax, that last step probably didn’t send you an email.

Pinax has an app in it called django-mailer that replaces Django’s send_mail with its own queuing version.  Mail gets queued up (you can see it in your admin section’s Home > Mailer > Messages) until you or a cron job run the command “python manage.py send_mail”.  
Try running ”python manage.py send_mail” (still in your virtualenv).  You should get an email.

Make sure you have all the Pinax apps’ email settings in your settings.py.  These depend on your particular desired configuration, but the ones that should be True for sure are ACCOUNT_REQUIRED_EMAIL and ACCOUNT_EMAIL_VERIFICATION.
ACCOUNT_OPEN_SIGNUP = True
ACCOUNT_REQUIRED_EMAIL = True
ACCOUNT_EMAIL_VERIFICATION = True
ACCOUNT_EMAIL_AUTHENTICATION = False
ACCOUNT_UNIQUE_EMAIL = EMAIL_CONFIRMATION_UNIQUE_EMAIL = False
EMAIL_CONFIRMATION_DAYS = 2
EMAIL_DEBUG = DEBUG

Now, the last thing you need is a cronjob to send the queued mail every minute, and to retry the deferred mail every 20 min.  How do you create this cronjob?
“crontab -e” opens up an editor.  Enter something like the following 2 lines.  ”env” is my virtualenv, and “djangopackages” is my Pinax project directory.  I have a blank line at the end of mine, which you might need.
* * * * * (cd /home/dp/djangopackages; ../env/bin/python manage.py send_mail » ../cron_mail.log 2>&1)
0,20,40 * * * * (cd /home/dp/djangopackages; ../env/bin/python manage.py retry_deferred » ../cron_mail_deferred.log 2>&1)

If you haven’t picked a default editor yet, it’ll give you a choice.  I like nano for this kind of thing because it behaves like a normal text editor.  Save the file and exit.  The cronjob should be automatically installed.  
Now restart Apache and try signing up for an account on your Pinax site.  You should receive an account verification email within a minute or two.  Check your Spam and All Mail folders.  You’re done.

If you didn’t get one, it’s probably an issue with the paths specified in your cronjob or access permissions.  Make sure your virtualenv’s set up properly and that the path to its Python is correct.  And make sure ../cron_mail.log and ../cron_mail_deferred.log are writeable.  Try “touch cron_mail.log” from the appropriate directory.  
Other notes

You can set up your project to use Gmail’s SMTP server, but Postfix is easier.  Gmail uses a different port for SMTP than the usual port 25.  I think it’s port 587.  But this only works for addresses like yourname@gmail.com. I believe.  I don’t think you can do this with Google Apps for Domains.
If your Pinax site is live, don’t do “python manage.py send_mail” until you’ve made sure the message queue is clear except for your own email address.  You could accidentally send out emails to all your users, like I did a couple of hours ago.  Those delayed confirmation emails will all have broken links and confuse your users.

How to optimize large image files for the web, the command-line way

I use Inkscape to draw all my vector graphics nowadays.  Inkscape has an analagous “Export Bitmap” feature that lets you export PNGs, but it’s pretty basic (I assume by design).

But what do you do once you’ve got that 400k Twitter background .png file exported from Inkscape?  
Or what if you want to do better than the image compression options in Adobe Photoshop or Illustrator, or even the GIMP?

Here are 2 decent options, assuming you’re starting with a lossless PNG file:
  • optimize the PNG by throwing out unused data and reducing colors
  • convert it to a lossy JPEG (hopefully not too lossy, eek)
GIF is not really an option now that PNG files are well-supported, unless you’re making lovely dancing animated GIFs.  
BMP?  TGA?  Other formats?  These aren’t good for web graphics.  It’s 2010, and web-suited bitmaps are JPG, PNG, GIF.  

Side note: I hope vector formats like SVG will be more supported by web applications (e.g. as Twitter avatars and background designs) in the near future, but it’s a steep uphill battle.  I don’t think it’ll happen until cameras are capable of taking vector photos.
The starting image

Before trying either option, here’s the image that I began with.  This is the PNG that Inkscape generated via Export Bitmap:

Option 1: Shrinking the PNG into a smaller PNG
I used OptiPNG to trim the useless data, shrinking my file from 389k to 318k.  This step doesn’t lose any image data.  
$ sudo apt-get install optipng
$ optipng twitter_bg.png

In particular, OptiPNG trimmed the alpha data from my PNG, which didn’t have any transparency.  These were just wasted bytes.
Then, I used Pngnq to quantize the image.  In other words, to decrease the number of colors in the image to an optimized smaller set of colors.  

(Photoshop and Illustrator let you choose the number of colors in the “Save To Web” tool.  Here we are doing the same thing manually.)
$ sudo apt-get install pngnq
$ pngnq -n 256 -s 1 -e b.png twitter_bg.png

The parameters I chose here are:
  • -n 256:  256 colors, which is the max resulting palette in pngnq.  Less than that would be too little to do my gradients justice.
  • -s 1:  Sample every pixel during its palette-picking algorithm.  The default is 3, but I found that s=1 improved certain parts of my image drastically.  The only drawback is a slightly longer wait (a couple seconds longer for my image).
This 256-color quantization can look pretty drastic if you’ve got a lot of gradients, as was my case.  But it shrunk my 318k PNG down to a tiny 99k.  Here’s the resulting image:

Option 2: Converting the PNG to a JPEG, lossily
You can convert from PNG to JPEG using GIMP if you’re more comfortable with a GUI than with the command line.  You have less control over the way the result looks, but it’s often good enough for web viewing purposes.  

I don’t know what’s under the hood of the GIMP, and googling it for a few minutes didn’t tell me.  Supposedly resizing images downward in GIMP isn’t as good as you can get with the right parameters in ImageMagick.  But this is just a rumor.  If I remember to look into it when I have some free time, I will.  Who knows, GIMP might even be using ImageMagick for downscaling.
Anyhow, you probably have ImageMagick installed already (unless you’re on Windows, then you probably want to install it through Cygwin), so just go ahead:
$ convert -compress JPEG -quality 87 twitter_bg.png twitter_bg.jpg

I found that 87% compression was the lowest I could deal with.  But even that gave me a 187k image, and that was with enough blurriness to be mildly noticeable.  Note the artifacts in the rainbow bands.

I’d rather give up colors and have zero blurriness than keep all the colors and have mild blurriness.  Which is why I went with PNG color quantization in the end.
ImageMagick gives you a lot of other compression options.  I tried compressing to various degrees using JPEG2000 rather than JPEG compression, but I didn’t notice enough improvement one way or another.  JPEG compression just looks bad when you’re dealing with vector graphics or text.  You need those crisp edges.  Lossy JPEG is more of a photo type of compression.

Summary
There, I’ve written up as much as I could about the 2 options that were reasonable to me.  Pick option 1 if you’re dealing with bitmaps exported from Inkscape or other vector graphics.  

But try option 2 if you’re okay with some blurriness due to lossy compression artifacts.
Not all image compression is the same!  It’s worth experimenting with various image compression tools and libraries.  

And if you try them all and still hope for better compression or quality, do some research on image compression algorithms and a little coding :)

How to make perfect sweet potato fries

Last month my friend Ruza and I tested various combinations of sweet
potato fry cooking methods. Here are the results of our experiments.
I was hoping to post this as an instructable, but I forgot to
photograph the fries that won the experiment (they got eaten too
fast). Most optimal: very crisp outsides of 90% of fries, with fully cooked
middles. Only about 10% burnt. I wish I had a final photo of these
ones. You won’t find any sweet potato fries as good in any
restaurant.

1. Slice a sweet potato into fries of variable length x 5/8” width x
3/16” depth.
2. Soak uncooked fries in water for 30-45 min.
3. Bring salt water to a boil, then add fries and boil them for 7-10 
min or until tender enough to eat.
4. Drain cooked fries and transfer to a pan containing 3 tbsp hot
olive oil. Cook on low heat roughly 10 min or until they transform
from floppy to crisp, flipping as needed.

Very delicious and interesting low-fat, extra-sweet (due to
caramelization in oven not added sugar), chewy fries:

1. Same as above.
2. Same as above.
3. Coat baking sheet with olive oil spray. Lay uncooked fries in a
single layer on baking sheet. Coat top surface of fries with another
light layer of olive oil spray. Sprinkle with salt and pepper.
4. Bake at 250 F for 2 hours. Far less tasty variations:

Pan-frying the fries without boiling them first results in crisp but
40% burnt fries. The fries’ insides take longer to cook through,
leaving the outsides to burn in the meantime. Pan-frying over medium-high heat rather than low heat results in 66%
burnt, 34% undercooked fries. Burnt fries still taste great, but they
could be far greater.

Soaking uncooked fries overnight, then boiling and frying them removes
most of their sweetness. Unsweet sweet potato fries are disgustingly
inedible. They look good, but it’s false.
Baking fries at 375-400 F for 40 min without any pre-soaking results
in well-cooked but non-crispy fries. They become floppy and fall
apart from their mushy floppiness. They taste great, especially when
eaten with a fork like typical oven-roasted vegetables. In contrast,
regular potato fries cooked in this way become crispy.

Other notes: I don’t know if the 30-45 min of soaking makes a noticeable difference.

Smaller sweet potatoes are easier to handle while slicing.

Serving static websites with Amazon S3+CloudFront, GoDaddy, Nginx, and a VPS

S3 is good for serving static files in situations where you may need
to deal with unexpected spikes in traffic. You can use any S3 
uploader such as S3Fox or S3 Organizer to create a bucket for your
files and then upload them. This requires no programming. With a couple more clicks, you can turn an S3 bucket into a CloudFront
bucket. Then, the bucket can be used as a simple content delivery
network. I pointed http://cdn.fuzzyrainbow.com to my CloudFront
bucket by editing my GoDaddy control panel cname settings for
fuzzyrainbow.com.

You’d be able to use the S3/CloudFront bucket as-is as a static web
server if it weren’t for Amazon’s inability to serve default index
pages. I fiddled with S3, CloudFront, and GoDaddy for a bit, but I
couldn’t get http://www.fuzzyrainbow.com to automatically serve
index.html. My quick solution to this was to install Nginx on my VPS to serve the
default index page and the .js files. I put those files into a
directory on my VPS and edited my nginx.conf to serve those files.
The images and stylesheets linked from index.html are retrieved from
http://cdn.fuzzyrainbow.com, my fancy little CDN.

I’ve put up the files for http://www.fuzzyrainbow.com here:

Pulling personal data out of OpenSocial containers and into a standalone website

I’ve been struggling with the OpenSocial docs and various samples,
trying to find a way to pull my personal data out of my Orkut profile. First I tried out the OpenSocial Python Client library samples and the
Google Friend Connect Chow Down sample. I didn’t fully understand
what was going on, but I saw that I’d need a consumer key & secret.
(I just learned about GFC yesterday and am still trying to figure out
what it can and can’t do.)

I created my own gadget.xml, uploaded it to a server, and added it to
my Orkut sandbox profile page. I verified my ownership of gadget.xml
with Google’s “Gadget Ownership Verification” tool, at
https://www.google.com/gadgets/directory/verify. That gave me my
Orkut gadget consumer key and secret. Then, I discovered some interesting info here:
http://sites.google.com/site/oauthgoog/2leggedoauth/2opensocialrestapi
1. Orkut only supports 2-legged OAuth.
2. A 3rd party site containing no gadget needs to use 3-legged OAuth
to retrieve a user’s Orkut profile data.

What is 3-legged OAuth? For example: your website has a “Login with
Twitter” link that sends you to Twitter for approval, upon which
Twitter sends you back to your website with an access token. In contrast, a 2-legged OAuth example: your Orkut (or Hi5, Ning,
MySpace, whatever) gadget requests data from your own personal API
server, for use in the gadget itself. In this case, your gadget uses
a shared secret from the OpenSocial container to sign its requests.

I guess I have 3 options now:
1. Give in and have everything live inside of an Orkut gadget
2. Create an Orkut gadget that pushes my profile data to my server and
then sends me to my website
3. Switch to another OpenSocial container that supports 3-legged OAuth
(if any exist) or to another social media site that has it (Twitter?
maybe Facebook Connect?) To be continued…

{Filename?} Price It By Phone, and the Twilio API

I won the Twilio+AppEngine contest with Price It By Phone, an app that lets you look up Amazon.com book prices by touch-tone phone.  Right now it’s up and running at http://price-it.appspot.com.

If you try it and run into problems, please let me know!

My interview with Twilio is here.  I like the Twilio API a lot.  It’s the easiest-to-use API imaginable.  You set up your Twilio phone number with a URL to post to.  Then, when you call the phone number, Twilio sends a POST request to that URL with the caller phone # and the digits entered as parameters. 

They have a Twilio-AppEngine sample among their demo apps.  This is awesome.  As you can see, I’m back to really liking GAE again, a lot.I’m putting a bit more time into Price-It and hoping to launch v2 soon.  Features that I want to put into it for sure:  support for ISBNs with Xs and any other chars that appear in them, user accounts, verifying your phone # before you’re allowed to see your book lookup history, being able to delete your history.  Possible features to be added: integration with Amazon wish list, FB connect. 

Also, I want to make it look web2.0 shiny, with cute illustrations and bright, designed gradients.  Yes, I know that the dark, trippy background doesn’t have mass appeal.  Sometimes I make art for the sake of making myself happy :)  View the page’s source code to see how it’s done. If you have other feature ideas, I’d be interested in hearing them.
