Now I use: “Silver is the New Black” – Silver is the New Black. Howdy! This theme, Silver is the New Black, is now retired.

I am going to try these until i get one i like. But first

google how to backup my wordpress.com blog

I am now doing Download your content

I Choose the New Theme

[copied from my notes in MS Word]:

webdesignerdepot

·         OneColumn

·         White Paper

·         WP Jurist

·         Best Theme

None of the above show up for free in wordpress.com

I try

·        TRVL – it’s OK [too dark, nice and wide & big]

·        Truly Minimal – seems better than TRVL – I like it – my pic shows up – Python Notes page might be a bit goofy ala code – kind of OK

·        Ryu – TOO BIG – NO MAYBE

·        Superhero – not bad – goofy black bar follows down NG!– Truly Minimal is better

·        Responsive – Feature-full theme with numerous page layouts, widget areas, custom menu areas, breadcrumb naviagtion, a homepage template, social icons, and responsive CSS. PRETTY GOOD

·        Forever – I am using this in the web2py book – not for here

·        White as Milk – NO GOOD

·        Sapphire – bad paragraph spacing like my present theme

·

between Responsive & Truly Minimal

Responsive – looks confused with my formatting

Truly Minimal – looks less confused with my formatting

I choose Truly Minimal

Result – Better than a jab in the eye with a sharp stick. The pages aren’t compact enough top to bottom.

App Engine MVC

I just scratched an itch to break out the App Engine Guestbook Tutorial into what satisfies me as a simple MVC framework (file/directory structure). The main benefit is to do data hiding on the model and controller (handler) classes to get them into different modules and so improve readability for me.

Small Changes

  • Figuring out the imports was a bit tricky.
    There may be a better way but this worked.
    GuestbookM.py (the Guestbook Module) contains the class Guestbook, etc..

  • In class MainPage
    NOW:
    path = os.path.join(os.path.dirname(file), ‘../v/templates/MainPage.html’)
    WAS:
    path = os.path.join(os.path.dirname(file), ‘index.html’)

  • I used the guestbook6_templates.py version available here. The index.html file is now in MainPage.html. The app name is jmvc. Here is the file structure:

jmvc/
    c/
        __init__.py
        GuestbookM.py
        MainPageM.py
    m/
        __init__.py
        GreetingM.py
    v/
        stylesheets/
            main.css
        templates/
            MainPage.html
            __init__.py
    app.yaml
    main.py

All init.py files are blank. As I said before MainPage.html is the same as index.html in the non MVC code. Here is the source for each of the remaining files :

# app.yaml

application: jmvc

runtime: python
api_version: 1
