Using request library for Pirates  Few years ago using urllib2 was a simplest way for sending and receiving  HTTP Request. But now I'm using  Request library . This  is more simple and powerful. Unfortunately Request is not include in default install and Pip  should be used .  Installation  Procedure is really simple  and near to standard : MacBook-Pro-Hohlov:pirates skhohlov $ virtualenv ./env New python executable in ./env/bin/python2.7 Also creating executable in ./env/bin/python Installing setuptools, pip, wheel...done. MacBook-Pro-Hohlov:pirates skhohlov $ source ./env/bin/activate ( env ) MacBook-Pro-Hohlov:pirates skhohlov $ ( env ) MacBook-Pro-Hohlov:pirates skhohlov $ ( env ) MacBook-Pro-Hohlov:pirates skhohlov $ pip install requests Collecting requests Using cached requests-2.13.0-py2.py3-none-any.whl Installing collected packages: requests Successfully installed requests-2.13.0 You are using pip version 7.1.2, however ...

Programming is easy. Really easy. Many years ago programming requires good skills in hardware and software. "How computers works" was really important question 30 years ago. Cracking Enigma computer or first computer at a nuclear submarine were more simplest the modern cell phone.  This is a reason why building mathematical solution requires perfect engineering skill. Computer is more powerful now and  tarting programming does not requires long term eduction. For example: driving car does not requires deep knowing in  engines and physics, you are driver not mechanics. Downloading software.  First  download  python. python   Also text editor  or powerful IDE is needed. I like Emacs but a lot of peoples love pycharm. You can download it  from  PyCharm . Python is really popular and a lot of system have it included. I'm planning  to use some additional libraries  for our application. It is good idea do not touch your ori...

Plarium again. How to start programming due to game playing.  I would like to say that writing a small script which is helping to have advantages against other peoples is not good. Writing  this post I have a goal to prepare a way to the fanny world of the programming.  I hope this article helps to use computer not a game machine only.  Previous article related to this one  is placed at : old script Requirements Internet browser with developer tools. Firefox or chrome are a good choice.  Both of them can be installed at the any popular operations system.  Download links are there:  https://www.mozilla.org/uk/firefox/new/ and https://www.google.com/chrome/browser/desktop/index.html. Also developer extension is needed: this is for firefox Plarium company uses flash and flash decompiler (in some case debugger) is required. I've used   JPEXS Free Flash Decompiler . Download link is here : https://www.free-decompiler.com/flash/download/...

few notes about google games. Goggle informed that access to the all games be closed after June, 30. I played "Pirates: Tides of fortune" and decided to limit my game time using small script. Detail is below. Some history First internet games were updated network games only. 15 years ago internet connection requires a lot of money and nobody had a problem with lagging of the other players. Usually games uses personal communication protocol. Warbirds, Aces High and Eve online use this way. Next part use a browser and trivial HTTP protocol. One of the popular game in this area is travian . Travian player uses browser and every browser (PC, cell phone, tablet) can be used for playing. Of course, popularity of the game is related to graphics. Trivial HTTP does not have good power in this and other technology is used for this side. One of them is Flash . Unfortunately flash requires a lot of CPU : "Pirates" was near to froze at my old celeron with ...

Lists are native part of the Python language and this part makes programming easy and speedy. But every Moon has a dark side and I would like to add some light to it. Problem of the list is heavy resource's usage. Everyone should keep in mind this during coding. Simple example from python tutorial: myfile = open("myfile.txt") myfile.readlines() Python opens file and creates a list from each line in it. Simple script below provides some information about executing speed and memory usage: #!/usr/bin/python import datetime import resource currenttime = datetime.datetime.now() print "="*20 print "Creating a file " print "="*20 myfile = open("textfile.txt", "w") simplerange = xrange(10000000) try: for i in simplerange: myfile.write(unicode(datetime.datetime.now())) myfile.write('\n') finally: myfile.close() timespend = datetime.datetime.now()- currenttime print timespend print "=...

I have few services which use MySQL as database server. I would like to have information about load in PNG  image  or  in Cacti app. MySQL   has  performance information at 'SHOW STATUS' command. Values  which  are monitored :   threads_running, threads_connected, thread_cached, slow_queries  Of course,  it is really easy to add more variables. Connection to MySQL is accomplished by MySQLdb  module. Typical example of usage is below : import MySQLdb mydb = MySQLdb.connect(host = 'hostname', user = 'username', password = 'secret', database = 'mysatabase' ) mycursor = mydb.cursor() mycursor.execute('SQL command') sqlresult = cur.fetchall() Storing data in rrd file is aviable via rrdtools package. This one is present in debian and Centos OS. example of creating file is below: import rrdtool rrdtool.create("myfile.rrd" , "DS:value1:data...
