Lessons Learned from Kathmandu

Published on Monday, January 14, 2013

Our first trip to Kathmandu is now over, so there are some lessons learned I should scribe. Some of these are obvious, and which we abide by whenever travelling, and some we simply forgot in our (very) impromptu trip to Nepal.

1) When agreeing on a price, make 100% sure the other person states the price back to you. I thought a price had been agreed to when the other person responded "ok ok, you are a lucky man", but this does not count. As they say, reconfirm, reconfirm, reconfirm.

2) When arriving at the airport, make sure you have small bills, too. We had 3x 100RS, 1x 10RS, and then a few 500RS. The price we negotiated was 440RS, and it would have been nice to have paid the exact amount.

3) Kathmandu is polluted and dirty. I cannot emphasise this enough. It is dirtier than probably any other city we have been to. If we come back, we will be bringing masks. I know this sounds silly, to wear a mask, but any local on a motorbike or in a taxi wears a mask, and many just walking around. Instead of the normal cloth masks that many people use, I would probably bring a make with finer grained material (maybe not N95 quality), and something with activated carbon. I'd probably get a mask like one of these. We ultimately tried to avoid walking on main roads, but having some activated carbon absorb something would have made it a little less unpleasant.

4) My wife's tip: bring dirty cloths, and throw them away after the trip. Or just bring black. Her beautiful blue jacket is now pretty filthy, with grease covering parts of it.

5) Bring some toilet paper. Similar to other parts of Asia, the bathrooms don't have any.

6) Bring a flashlight. The load shedding makes the city dark, and if you go out, you will want a flashlight. There aren't any lights. We only used it a few times, but I am really glad we brought two flashlights with us.

7) Bring vitamin C and lots of hand sanitizer. We did, like we always do when we travel, and I'm really glad we did. Everybody is coughing or sick, and everybody spits. It is similar to the situation in China, i.e. everyone spits. Then everybody gets sick. Bring hand sanitizer.

8) If you take a bus somewhere, try to ask when you buy tickets to sit on the left side in the middle. The front is a no-go for me. We typically had seats in the rear right, but on the curvy roads I think the left middle would be safer, as oncoming buses won't hit you. One bus on the way back had the left side decimated. If you do a search on "nepal bus crashes" in images.google.com, you will quickly see why you don't want to be in the front row.

9) Our hotel rooms all typically had just one power outlet. If you bring multiple electronic devices, bring some way to  charge more than one at a time. Something like like this travel charger would work well.

10) Bring clothing to stay warm at night. We travelled to Nepal in winter, and all our rooms got pretty cold at  night.

Enjoy!

Migrate Custom Blog to Blogger

Published on Thursday, January 10, 2013

For the last ten years I have run this website from various systems. First it was on Wordpress, then Mambo, then Joomla, and since early 2006 it has been running on custom code written using Django. I used this site as a learning tool for Django, re-wrote it after gaining more knowledge of Django, and then re-wrote it again when Google released App Engine. However, I recently realised that for the last few years I have spent more time writing little features than actually writing. I have entire trips that I never wrote because I was too busy writing code.

This week it all changed. I did the unthinkable. I moved this website to Blogger.

After evaluating some of the features of blogger, i.e. custom domains, location storing, ability to filter on labels, custom HTML/CSS, great integration with Picasa, and their mobile app, I realised I could virtually replace everything I had previously custom made.

This post gives a technical description how to migrate a site running Django, but readily applies to any blog running on custom code. I initially spent a fair bit of time trying to figure out how to convert my existing RSS feed into something Blogger could accept, but every solution required troubleshooting. I soon remembered why I love Django so much, and that it would be trivial to generate the correct XML for import.

1) Create Blogger Template
I wanted to keep my design, so I hacked it to support Blogger. Take one of the existing templates, edit the HTML, and adjust it for your design. If you've worked with templates before this shouldn't be too difficult.

2) Generate Sample XML
The first step was to generate a sample XML file from Blogger to see what would be needed for import. Create a sample post with a unique name and a few labels, and location. In Blogger, go to Settings->Other and click Export Blog. The first 90% of the file will be for your template and other settings, but eventually you will find a section with <entry> elements in it. Copy this sample element out - this will become your template.

3) Format Template
Using the sample section from the blog export, format it so the view you will create populates it correctly. A note of caution: the template needs time in ISO 8601 format, you need the <id> element, and the location element needs coordinates if there is a name. It won't import later if there is a name with no coordinates. My template looks like this:

feeds/rss.html

{%  load blog_extras %}
{% for entry in entries %}
    
        tag:blogger.com,1999:blog-1700991654357243752.post-{% generate_id %}
        {{ entry.publish_date|date:"Y-m-d" }}T10:30:00.000123
        {{ entry.publish_date|date:"Y-m-d" }}T10:30:00.000123
        
        {% for tag in entry.tags %}
            
        {% endfor %}

        {{ entry.title }}
        {{ entry.content }}

            kelvin@example.com
            
        
    
{% endfor %}

This isn't really RSS, so if you are pedantic you can name it something else. You will notice I loaded some template tags in there ("blog_extras"). This is for generating the random number, as this is needed for the ID element.. Here's the template tag.

blog_extras.py

# 'import random' at beginning of file
def generate_id():
    id = ""
    for x in xrange(1, 7):
        id = id + str(int(random.uniform(400, 900)))
    id = id + "8"
    return {'obj': id}
register.inclusion_tag('blog/generate_id.html')(generate_id)

/blog/generate_id.html

{{ obj }}

4) Create Code To Populate View
This section should be easy if you have written your blog in Django. Simply populate the template, what I have shown as "rss.html" above

blog/views.py

def show_rss(self):
    q = Entry.all()
    q = q.filter("genre !=", "blog")
    entries = q.fetch(500)
    return render_to_response("feeds/rss.html", {
        'entries': entries,
        }, mimetype='text/plain')

I did a filter on the model to not include "blog" entries - these are my travel stories, and I exported them separately. Remember that this is all happening on App Engine, so you will need to adjust if using Django's normal ORM.

5) Download Entries
Visit the URL you mapped to the "show_rss" function in urls.py, it should generate your list of entries. Copy and paste those entries into the exported XML from Blogger where you took out the original <entry> element.

6) Import Entries
Now go to Blogger and import your blog. With any luck you will have imported all your entries. You will probably need to do this a few times as you tweak the text. I had to remove some newlines from my original posts.

Optional Steps

7) Create Redirect URLS
Links in Blogger appear to only end in .html, which is a problem for links coming from Django. Luckily, Blogger includes the ability to add redirects. Go to Settings->Other-Search Preferences. You can then edit redirects there. I generated a list of my old URLs and combined that with a list of the new URLs. Hint: you can use Yahoo Pipes to extract a list of URLS from a RSS feed. If you open any of the links in Excel and split on forward slashes, remember that it will cut off leading zeros. Set that field to TEXT during import.

I decided not to create redirects for every entry, as I didn't really have time, and it only probably matters if somebody links directly to that page. I opened Google Analytics and looked at the Search Engine Optimisation page and sorted it by the most used inbound links. After getting down to entries that only had 1 inbound request per month I stopped creating redirects.

8) Host Stylesheets and Images Externally
Blogger won't host host files, so you need to work around this problem. All my images are generally from Picasa, except very specific website related ones. I moved those to Amazon's S3 and updated the links. I did the same with my CSS. You could probably store them in Google Storage, too.

9) Create Filters on Labels
If you had any previous groupings you can still link to them using label searches (in my case I actually added the "genre" as a label). The syntax is "/search/label/labelname/", as you can see in my howtos section link.

10) Update Webmaster Tools
If your site is part of Google's Webmaster Tools, you will want to login and take a look that things are OK. You will also probably want to update your sitemap (send Google your atom.xml feed).
