Want to learn to Program in Python? Why not have a whole lot of fun while doing it!

My reddit post on learning Python by implementing computer games has over 300 upvotes! I do agree that programming should be fun and that learning from games is way more fun that a dry textbook. Of course, later you would want to learn from these legendary text:

  • Structure and Interpretation of Computer Programs – Python implementation of examples

the MIT book that replaced the legendary SICP (even though that has been re-implemented in Python). And the also Algorithms in Python will help you pass all those starchy, stiff job candidate tests.

The necessary zend_extension line could not be found in the configuration.

Part Zero of this puzzle:

You cannot simply copy 00-ioncube.ini to the directory they tell you to. You must symlink it from /etc/php5/mods-available into /etc/php5/fpm/conf.d 

Part One

The first part of this puzzle has been solved after many an hour of hacking, and it came from this StackOverflow thread, where an individual stated:

You can output the php.ini file path with phpinfo(INFO_GENERAL); Did you restart your web server ?

Are you using php-fpm (php5-fpm) so then you have to restart php-fpm also..

So the problem I was having was that after adding that file, it was not being recognized by the server as an additional file to be parsed because php-fpm had not restarted and it was returned a cached list of files.

schemelab@schemelab2:~/domains/org/metaperl/tmp$ sudo service php5-fpm restart
Restarting PHP5 FastCGI Process Manager: php5-fpm.
schemelab@schemelab2:~/domains/org/metaperl/tmp$ sudo service apache2 restart

A different view of Google

From this reddit thread we have this dirt on G:

They stole search from RankDex, gmail was in beta for 8 years and the search still sucks balls, google maps is allright, android was acquired by them and is still in beta (not officially, but have you seen the problems they’re having?), chrome started out promising but gets worse and worse, Google voice was a neat idea that was stillborn and their mismanagement of G+ and hangouts is legendary. Reader, iGoogle, Google Talk, Google Health, Knol, Picnik, Buzz, Wave, aardvark, notebook, dictionary, dodgeball, jaiku, lively, pagecreator, answers, Google Plus, Google Glass, Google Nexus Q, etc. etc. etc. There’s more dead projects than live ones.

If you cannot install wordpress themes because you get the error “installation failed unable to create directory”, help is on the way

I just unpacked a fresh install of WordPress 5.2.1… at first I could not upload themes. But this was fixed by chmod 777 wp-content/uploads.

Then the themes installed via ftp would installed, giving me the error “could not create directory”. I fixed it by doing this:

Just login to your webserver. Then change directory to the root of the wordpress site. And type in the following incantation:

sudo chown -R www-data:www-data .

.. tada! And dont forget the dot at the end of that command.

HTML is a data structure

From reddit user remy porter in the thread “Is Separating HTML and JavaScript Harmful? ” we have:

The problem is that most frameworks misunderstand what HTML is.

HTML is a data structure. Specifically, it’s a semantic data-structure for holding human-readable information. It is the backing-store of a presentation layer, it is not, itself the presentation. CSS is a rule-based system for defining how to map that backing-store into actual rendering. JavaScript is a tool to manipulate that data.

The purpose of our MV- frameworks is mostly to map actual data- XML or JSON- to our HTML backing store. Their mistake is thinking of the HTML as a view- HTML does not have the concept of a “View”, and bolting the view on is awkward and leads to all sorts of tooling issues- which is mostly what the author is complaining about. These are valid complaints, but they don’t arise from separation- they arise from leaky abstractions.

 

 

scala book pdfs

When I wanted to learn Scala, my first steps were to get Scala, SBT and Intellij IDEA installed. And then I needed to get IntelliJ IDEA to know about my locations for scala, scalac, and sbt.

The next step was to find some offline resources, so I could learn on the train. Here are enough resources to get you going:

Happy hacking!
