I have made a javascript equivalent, compose your mazes and get them solved. P.S. don't try to put more than 3-4 cars! the algorithm is not optimized yet.
Ryan Bates continuously provide useful Rails tips in this railscasts.com . I had written a bash script for downloading the videos of the episodes in the past. I do not like streaming much and I'd rather keep the episodes for reference. One downside of the script is that I had to check the rss feed or the website for new episodes, and run the script manually passing the correct paramters (start and end of episode ids to be downloaded) Now I decided to get rid of the silly step. so I ported my script to ruby, and it runs down to download whatever episodes are missing using the rss feed and checking what is already present. The script uses simple-rss gem, so you'll have to get that installed. It also uses wget for downloading. I didn't bother using net/http of ruby, wget is fine for me as a linux user. The script flow is simple: Check the current files in the download directory (collecting information) Grab the rss of railscasts.com Iterate over rs...
While working with data, we tend to deal a lot with CSV files. It is more efficient and trivial to manipulate csv data either through command line tools or through programming languages like ruby. However, occasionally we need to convert files to MS Excel format before sending them to 3rd party. Gnumeric is a wonderful opensource spreadsheet program. It contains a command line convertion tool called ssconvert that can be used to perform direct conversion among lots of supported formats easily from the command line. For example, conversion from csv to xlsx can be done via ssconvert file.csv file.xlsx OR ssconvert file.csv --export-type=Gnumeric_Excel:xlsx It can be installed in ubuntu via apt-get install gnumeric In order to convert lots of files, I wrote a simple bash script that will process all csv files in the current directory and generate the corresponding xlsx files. The script came pretty handy in data preparation. I believe i can be h...
Entrepreneurship has become one of the one of the most interesting topic in the business side in any country in the world. While it is digging its way in the middle east, there is some sort of confusion and a lot of aspects related to that topic. A Startup can act and advance to tackle business opportunities in a way that competes with large enterprises. and most of the times, they need to be supported by Investors to back them up. One of the things that started to really bother me in the culture is the definition of success of a startup. No one denies that a decent revenue generating startup is a successful one. However, some people believe that just raising an investment is a success.... umm, debatable. I believe we can make some kind of analogy with some entities that showed up in the past decade like biznas and skybiz (I'm sure some of you will remember those names). they used an invalid scheme summarized as: People can register and join the network for a fee (as an i...
