Redcarpet instead of kramdown as markdown renderer

Vieux Port de Montréal, October 2015 - Oneplus oneRedcarpet is the engine written in C by Github, It’s also known as Github flavored markdown. I’ve been using kramdown since the beginning but apparently redcarpet has some cool features like autolinking.For example if you put a link in your post without using <url> notation or [url text](url), kramdown does not convert those urls into <a> tags. Instead it renders them as raw text in <p> tag.Here is my config.yaml:markdown: redcarpetkramdown: input: GFM hard_wrap: falseredcarpet: extensions: ["autolink", "fenced_code_blocks"]Here is the full list of available redcarpet extensions:https://github.com/vmg/redcarpetBtw fenced codeblocks kicks ass, just put your code like this:```foo.bar()```

Serving subdomains of localhost, no apache2 conf needed

Trabzon, August 2015 - Oneplus OneFor my latest project, I implemented subdomain handling, however, I wasn’t able to test it from my local; pushing to production and try from the real domain and subdomain was so hard. When I look at the tutorials, they are mostly php stuff containing apache2 configurations, virtualhosts etc. I needed a simple method for this. Modify content of hosts file$ sudo nano /etc/hosts Example configuration127.0.0.1 localhost127.0.0.1 hakan.localhost Install web.py just for the sake of trial.$ sudo easy_install web.py Create a file$ touch main.py Paste this content:import web urls = ( '/(.*)', 'hello')app = web.application(urls, globals())class hello: def GET(self, name): if not name: name = 'World' return 'Hello, ' + name + '!'if __name__ == "__main__": app.run() Run the file.$ python main.pyOpen browser and go:

Rename files sequentially in a folder #bash

The output will be something like 0001.jpg, 0002.jpg etc. You can change the number of digits by modifying %04d part.a=1for i in *.jpg; do new=$(printf "%04d.jpg" "$a") #04 pad to length of 4 mv -- "$i" "$new" let a=a+1doneThanks SO

Weekly Roundup - 1

Flat Montreal is Flat - October, 2015 I read a lot of blog posts, RSS feeds, watch too many videos, solve too many big/little problem during the week. So instead of keeping them in my Keep; I decided to put small snippets here so that I can find them again easily and also maybe some other people can see it. I don’t know if I can write this every week. However, I’m a huge fan of HighScalability’s “Stuff the internet says on scalability” series. I’d like to do something like that. Since I’m not a master like them, mine will be a lot simpler, less sophisticated of course. I will also try to put some photos that I take on the way of being smartphone photographer :P Write ahead logginghttps://www.sqlite.org/wal.html A cool site:http://foundmagazine.com/ Another addictive game:https://play.google.com/store/apps/details?id=com.ketchapp.stack Google’s cute programming memories: https://bar.foo/ [web.py] CSRF decorator is not complaint with app process...

Solving mongodb's user creation problem

I have been test driving mongodb with some serious projects. I have always had difficulty in creating users in any database. Mongodb was no surprise.Here is the working command for me. Error 2016-02-16T01:28:27.570+0000 Error: couldn’t add user: User [email protected] already exists at src/mongo/shell/db.js:1004 First add the user: mongo localhost:12346> use admin> db.createUser({ user: "test1", pwd: "test", roles:[ { role: "readWrite", db: "isimibul-dev" }]}) Now connect by using the user:mongo localhost:12346/mydb-dev -u test1 -p testOne side note: If you are having difficulties with connecting to the DB, you can change auth mechanism to MONGODB-CR, this is the old system used back in the days of v2.4; now SHA is used for auth, if you are using an updated version like v3, just use SHA as auth mechanism.
