Ways to Run Python
- IPython is is recommended (http://ipython.org) (requires pyreadline)
- Also recommend running in a virtualenv sandbox for custom control of the environment.
- See the cheeseshop for package downloads (http://pypi.python.org)
virtualenv
- Creates an isolated python environment customized to your version and dependency requirements
- Comes with distribute, easy_install, and pip
- Allows control of environments where root authority is lacking
- Install and activate/deactivate:
- python virtualenv.py --distribute <new env>
- cd <new env>
- source bin/activate (or deactivate)
pip
- pip is the newest python package manager tool
- pip install <package name or package file>
- pip search <package name>
- Use --upgrade option for existing packages

Reserved for use by Python
tuple Type
- Tuples are sequences of other objects that cannot be changed (they are “immutable”)
- Tuples can contain any type of object, and can be sliced (remember, they’re ordered)
- A one element tuple is formed by (element,) where the comma makes it a tuple
- Examples:
tup = (1, "a", 3)
tup = tuple()
tup = (1,) # Comma needed for single element
gen = (x**2 for x in range(1,4)) # Not a tuple!
list Type
- Lists are sequences that can be changed (“mutable”)
- Lists can contain other object types and be sliced
- A list is a set of objects separated by commas and closed in square brackets
- Examples:
lst = [1, "a", 3]
lst = list()
lst = [x for x in xrange(5)]
dictionary Type
- A dictionary (“dict”) type is a set of expressions that are associated 1 to 1 with other expressions
- A dict provides a handy “mapping” between a “key” expression and its associated “value” expression
- A dict is not an ordered sequence, it’s a mapping.
- Examples:
dic = {"a": 1}
dic = dict(a=1)
dic = {x: ord(x) for x in range(97, 107)}
set Type
- A set is a mutable group of unordered immutable objects with unique values i.e. no duplicates (so the set is mutable, but not the objects within it)
- Uses the ‘{}’ symbols just like a dictionary, but doesn’t have ‘:’ i.e. no key/value pairs
- Slicing is not allowed (why?), but iterators work
- Set operations are powerful, but perhaps not the most efficient
- Examples:
st = {1,2,2,3}
st = set(1,2,2,3)
st = {x for x in range(1,4)}
yield Statement
- yield is similar to return, but suspends execution of the called function instead of ending the function
- On the next call to the function, yield picks up where it left off, with all identifier values still holding the same values i.e. loses its stack entry
- Appearance of yield signals a generator
with Statement
- The with statement is used to run a suite of other statements under a “context manager”
- Special methods __entry__() and __exit() are called to setup and takedown a “context”
- Common for doing i/o (which auto-closes the file handle) and threading (which auto-acquires and releases lock)
import & from Statements
- To make a set of identifiers in another module available for use by your module, you must first use import or from
- import pulls in identifiers from module(s) but the module name must be used as a prefix (only module name is added to local namespace)
- from pulls in identifiers from modules but avoids need to prefix with the module name (identifier is added to local namespace)
The calculator package
calculator
__init__.py
operations
__init__.py
arithmetic.py
display
__init__.py
scientific.py
algebraic.py
File Objects
Use the with statement if possible.
Why?
with open(“file_path”,<mode>) as fh:
# <mode> = “r” for read only; ”rb”
# “w” for write only; “wb”
# “a” for append
for line in fh:
<suite>
all_contents = fh.read() # read all chars
one_line = fh.readline()
as_list = fh.readlines()
JSON
- An “object” is an unordered set of name:value pairs (called “members”) separated by commas and surrounded by curly braces
- { Name1:Value2, Name2:Value,… }
- An “array” is a set of “elements” surrounded by square brackets
- [ element1, element2,… ]
- Elements are strings, numbers, true, false, null, object, array
JSON
- Strings are made of:
- Unicode chars (\uhhhh)
- \,\\,/,\b,\f,\n,\r,\t
- Numbers are signed integer, decimal, or exponent (“e”) flavors only
- Whitespace is fine
json Module
- import json
- Python object to serialized JSON object:
json.dump(python_obj, fo, **kwargs)
json.dumps(python_obj, **kwargs)
JSON serialized object back to Python object:
python_obj = json.load(fo, **kwargs)
python_obj = json.loads(string, **kwargs)
Note: JSON is not a ”framed” protocol
i.e.can’t append multiple JSON objects to same file
json Module
- JSON keys in key/value pairs are always strings. Unlike Python.
- Default json module encoder only encodes “ASCII-compatible” strings. Use u for other encodings
- Same name in name:value pairs uses the last one
- Out of range floats are handled correctly (nan, inf, -inf)
Python to JSON Translations
dict -> object
list, tuple -> array
str, unicode -> string
int, float -> number
True, False -> true, false
None -> null
Complex Serializations
- Accessing a deep object serialization can be a challenge
- Remember: only simple objects, maps, and arrays compose a JSON serial object
- Use subscriptions and keys to get around
pickle and shelve
- The pickle module does a similar job to JSON, but is Python specific
- Not good for machine data interchange
- Allows multiple pickled objects to be dumped to the same file (and must be loaded in same order on way back) but shelve is better solution
- The shelve module essentially provided a persistent dict for pickled objects in a database
Performance
- The builtin json module can be slow
- Other pypi packages have C extensions to speed them up e.g. simplejson, yajl, python-cjson, and UltraJSON
ReST
- A simple, client/server web services API currently in favor
- Way of locating and manipulating “resources” (usually XML or JSON documents) on a network
- Commonly based HTTP protocol (GET, POST, PUT, DELETE)
- Stateless (all state on client or server)
- Simple, predictable resource pathing scheme based on URL
ReST
- ReSTful services generally map a CRUD interface (Create, Read, Update, Delete) by URL mappings that embed data e.g.
GET v2/{tenant_id}/servers
- HTTP POST -> Create
- GET -> Read
- PUT -> Update
- DELETE -> Delete
- HTTP GET calls to a ReSTful service should not change state i.e. read only
Openstack ReST API
- Openstack uses ReST to implement it’s user-controlled cloud provisioning service
- Requires a set of “endpoint” URL’s which have service request data appended e.g.
- Adding “v2.0/tokens” to the Identity service “endpoint” URL, inserting login credentials, and POST’ing will return a “token” that allows use of the v2.0 API
- e.g. Adding “v2/{tenant_id}/servers/ips for the Compute service will return server IP addresses
Openstack ReST API
- See the Openstack API Reference at http://api.openstack.org/ for complete API
- Workflow to use Openstack API:
- Obtain tenant id and API key and authenticate (24 hour timeout)
- Extract token id and appropriate endpoint URL for the desired service from the response
- Send API request(s) to the appropriate service endpoint(s) including the X-Auth-Token HTTP header for each request
- If a 401 HTTP response occurs, re-authenticate
urllib2 Module
- Client functions to access URL’s
- import urllib2
- urllib2.urlopen(url[,data]) is a common call signature, where url is the URL of the target resource, and data is to be sent to the server
- Only HTTP uses data currently. If data exists, it must be URL encoded
- If data exists, HTTP GET becomes a POST.
MySQLdb DB-API
- Connection.cursor() emulates a cursor (MySQL does not support cursors directly)
- Connection.commit() and Connection.rollback() work for transactions
- User Guide at http://mysql-python.sourceforge.net/MySQLdb.html
- API at http://mysql-python.sourceforge.net/MySQLdb-1.2.2/
MySQLdb DB-API
- Examples:
import MySQLdb
lab_conn = MysqlDB.connect(host=“x”,
user=“me”,
passwd=“secret”,
db=“lab”)
lab_cursor = lab_conn.cursor()
lab_cursor.execute(“select * from bugs
where bug_type = %s
and genus = %i”,
(“butterfly”,3))
results = lab_cursor.fetchall()
Python Spawned Processes
- Python can spawn and control entire processes using the subprocess module
- Generally means redirecting the basic file descriptors (stdin, stdout, stderr) to gain programmatic access
- Forks a new process and uses pipes for redirection
- As usual, beware of invoking a process based on direct or indirect user input
subprocess.call()
- Use subprocess.Popen class for most use cases, unless a convenience method fits
- Run command specified in args and *, wait for completion, and return exit code:
- subprocess.call(args, *, stdin=None, stdout=None, stderr=None, shell=False)
- Don’t use pipes for stdout or stderr
- Only use shell=True if need shell features
subprocess.check_call()
- check_call() raises CalledProcessError exception if exit code not 0:
subprocess.check_call(args, *, stdin=None, stdout=None, stderr=None, shell=False)
- Don’t use pipes for stdout or stderr
- Only use shell=True if need shell features
subprocess.check_output()
- check_output() returns process output as a byte string:
my_out = subprocess.check_output(args, *, stdin=None, stdout=None, stderr=None, shell=False, universal_newlines=False)
- Don’t use pipes for stdout or stderr
- universal_newlines is to convert all line endings to \n
subprocess Module
- Can use subprocess.PIPE in stdin, stdout, stderr
- Can subprocess.STDOUT in stderr
- subprocess.Popen(args) constructor has many keyword args too.
- See http://docs.python.org/library/subprocess.html#module-subprocess
- Popen args should be a string or sequence (sequence preferred)
subprocess Module
- Note: if args is a string, must use shell=True to specify args
- Once again, don’t use shell=True with user entered data.
- shell=False does not call a shell either directly or indirectly, allowing all characters (even metacharacters) to be passed safely
subprocess Module
poll() sees if child is terminated
wait() waits for child to terminate
communicate(input=None) sends input to child stdin. Use instead of stdin.write()
send_signal(signal) sends given signal to child
terminate() and kill() send respective signals to child
subprocess Module
- Popen.std* are file objects if std*=PIPE was used in Popen constructor
- Popen.pid is child process ID
- Popen.returncode is child exit code. Set by poll(), wait(). None if child not terminated. If negative, indicates child was terminated by that signal number.
Python Decorators
- Decorators are syntactical sugar for function wraps
- Start with '@' followed by the decorator name
- The decorator immediately precedes the decorated function and is called instead when the decorated function is called
Decorator Example 1 (No Arguments)
def make_bold(fn):
def wrapped():
return "" + fn() + ""
return wrapped
def make_italic(fn):
def wrapped():
return "" + fn() + ""
return wrapped
@make_bold
@make_italic
def hello():
return "hello world"
print hello() #returns hello world
Python Decorators
- The decorated function reference is passed to the decorator, which can call it or replace it
- Decorated function arguments are also available to the decorator
- The decorator returns a new function which is executed
- See the built-in @property for an example
- Another example: @logging could add transparent logging to under-lying functions
Decorator Example 2 (With Arguments)
import string
def make_boring(fn):
def wrapped(var):
return fn(var.strip(string.punctuation).lower())
return wrapped
@make_boring
def print_me(var):
print(var)
print_me("HELLO WORLD!!!!!") #returns "hello world"
Threads
- Threads are independently scheduled streams of instructions that run within a single OS process
- Threads have their own stack, registers, scheduling attributes, priorities, signal mask, and thread local memory
- Threads allow logical concurrency of execution (and possibly parallel execution if configured)
- Threads introduce the need for synchronization!
Threads
- Threads share the same instructions (bytecodes) same identifier bindings, same open files, and other resources
- Threads cannot exist outside of an OS process
- Threads are “lightweight” – the overhead of creating them is much less than creating a real process
- Threads are used for capturing a higher % of available cycles on a single CPU, realtime systems, an asynchronous event handling.
Threads
- Thread synchronization
- coarse (involving an entire call)
- fine (a section of code)
- very fine (a single identifier)
- Thread synchronization failure can cause “deadly embrace” and/or “race conditions”
- Use thread-safe libraries
Threads
- User threads vs. kernel threads
- A programming abstraction
- Kernel thread designs differ substantially by OS
- Threads may or may not be implemented in the kernel
- “Green” threads are only implemented in the user process, and not mapped to kernel threads
POSIX Threads
- POSIX (Portable Operating System Interface for Unix) established the POSIX threads (pthreads) standard
- Pthreads provides a standard interface to maximize available machine resources and minimize complexity e.g. in parallel programming, load balancing, problem partitioning, communications handlers
- Most OS vendors and modern languages have ported the pthreads model, including Python
CPython Threads
- CPython does map user threads to actual kernel threads, BUT…
- CPython is not “thread safe”
- CPython forces a thread to obtain the Global Interpreter Lock (GIL) before running, effectively serializing threads to protect Python interpreter memory
- CPython forces GIL release every 100 bytecode instructions, allowing other threads to run
CPython Threads
- Thread-safe C extensions bypass the GIL
- Any blocking I/O also releases the GIL
- There exists ways to minimize or eliminate the effect of the CPython GIL
- run in optimized mode
- run under a C extension such as a shared library
- run under subprocess
- call time.sleep()
- set sys.setcheckinterval()
Threading Models
- Some common threading models exist:
- Boss/worker
- Boss thread creates worker threads, then loops receiving work requests from a queue or socket
- Worker threads loop on work requests from Boss
Threading Models
- Peer
- All threads work on the backlog without a “manager” thread
- All threads generate their own work requests
- Pipeline
- Each thread does a stage of a work pipeline
- Each thread accepts work from “previous” thread, passes to “next” thread
threading Module
- Main objects are:
- wait for a condition using a lock:
threading.Condition()
- wait for an event:
threading.Event()
- lock a critical section or variable:
threading.Lock() or RLock()
- classic semaphore acquire and release based on count:
threading.Semaphore()
threading Module
- Semaphore with a constained upper bound:
threading.BoundedSemaphore()
- Create a thread:
threading.Thread()
- Run a thread after timer expires:
threading.Timer()
- To create a thread, call Thread constructor with a callable object (or override run() method), then the thread start()
threading Module
- Calling another threads join() causes the caller to wait for thread to end
- Pass arguments to new thread using the args and kwargs keywords
- Locks have acquire() and release() methods that can be automatically invoked on the with statement
threading Module
- Condition variables have a wait() to wait for the condition to be reached
- Condition variables also have notify() and notify_all() that can be used to indicate to other threads that the condition variable has changed
- Semaphore objects also have acquire() and release() for easy use with with
- Event objects have set(), clear(), and wait() which indicate if event has happened or not
Multiprocessing Module
- Process-based (heavy) threads
- Similar semantics and methods to threading module
- Bypasses GIL issues
Multiprocessing Queue
- Thread safe
- Equivalent to Queue.Queue
- Provides easy producer/consumer patterns
- Works between processes
- get() and put()
Multiprocessing Pipe
- A second method for inter-process communication
- Cannot share same Pipe end among multiple processes
- Can connect two processes where each takes one end
- send() and recv()
Multiprocess locking
- May need to use cooperative locking across processes
- Same lock semantics as threading module
- Works across address spaces (processes)
Multiprocess sharing
- 2 shared memory facilities across processes
- Try to avoid -- better to use message passing
- multiprocessing.Array and multiprocessing.Value
- multiprocessing.Manager
- See http://docs.python.org/2/library/multiprocessing.html#module-multiprocessing
Test Driven Development
- Best early detection of bugs:
- Pair programming
- Continuous Integration
- Test Driven Development
- Test Driven Development (TDD) says essentially:
- Write a test that for a proposed feature and verify it fails
- Write the minimal amount of code to make the test pass
- Refactor
- Repeat
unittest Module
- Derive a class from unittest.TestCase
- For a test runner, unittest.main() is the default, or roll your own
- Simple test to see if two values were multiplied correctly:
import calculator.operations.arithmetic as arith
import unittest
class TestCalculations(unittest.TestCase):
def test_multiply(self):
""" test multiply 2 * 2 """
testVal = arith.mult(2,2)
self.assertEqual(testVal, 4)
if __name__ == "__main__":
unittest.main()
unittest Module
- If a test fixture is needed to setup/takedown the calculator for each test, we can add methods setUp() and tearDown()
- The naming standard is that each test method name start with test
- For unit tests, the TestCase class offers (3) primary verifiers:
- assertEqual(): result is equal to the value we expect
- assertTrue(): result is a True assertion
- assertRaises(): result is the Exception we expect
unittest Module
There are more assert methods to make life easy:
- assertNotEqual(): a != b
- assertTrue(): a is True
- assertFalse(): a is False
- assertIs(): a is b
- assertIsNot(): a is not b
- assertIsNone(): a is None
- assertIsNotNone(): a is not None
unittest Module
And some more:
- assertIn(): a in b
- assertNotIn(): a not in b
- assertIsInstance(): isinstance(a, b) is True
- assertIsNotInstance(): isinstance(a, b) is False
- assertGreater(a, b): a > b
- assertRaises(ex): raises ex
- assertRegexMatches(x, re): regex.search(x) is True
mock Module
- Mock is a library for testing in Python. It allows you to replace parts of your system under test with mock objects and make assertions about how they have been used
- Mock is now part of the Python standard library (versions 3.3+)
- Mock is designed for use with unittest. Mock is based on the ‘action -> assertion’ pattern instead of ‘record -> replay’ used by many mocking frameworks
mock Module
"Mock" and "MagicMock" objects create all attributes and methods as you access them and store details of how they have been used. You can configure them, to specify return values or limit what attributes are available, and then make assertions about how they have been used.
>>> from mock import MagicMock
>>> inst = Class()
>>> inst.method = MagicMock(return_value=3)
>>> inst.method(3, 4, 5, key='value')
3
>>> inst.method.assert_called_with(3, 4, 5, key='value')
mock Module
"side_effect" allows you to perform side effects, including raising an exception when a mock is called.
>>> mock = Mock(side_effect=KeyError('foo'))
>>> mock()
Traceback (most recent call last):
...
KeyError: 'foo'
>>> values = {'a': 1, 'b': 2, 'c': 3}
>>> def side_effect(arg):
... return values[arg]
...
>>> mock.side_effect = side_effect
>>> mock('a'), mock('b'), mock('c')
(1, 2, 3)
>>> mock.side_effect = [5, 4, 3, 2, 1]
>>> mock(), mock(), mock()
(5, 4, 3)
mock Module
The patch() decorator / context manager makes it easy to mock classes or objects in a module under test. The object you specify will be replaced with a mock (or other object) during the test and restored when the test ends.
>>> from mock import patch
>>> @patch('module.ClassName2')
... @patch('module.ClassName1')
... def test(MockClass1, MockClass2):
... module.ClassName1()
... module.ClassName2()
... assert MockClass1 is module.ClassName1
... assert MockClass2 is module.ClassName2
... assert MockClass1.called
... assert MockClass2.called
...
>>> test()
mock Module
Things to remember about "patch":
- When you nest patch decorators the mocks are passed in to the decorated function in the same order they applied (i.e. the order that decorators are applied). This means from the bottom up, so in the example above the mock for module.ClassName1 is passed in first.
- Be mindful of namespace when using patch. It matters that you patch objects in the namespace where they are looked up.
mock Module
"patch" can also be used with context managers:
>>> with patch.object(ProductionClass, 'method', return_value=None) as mock_method:
... thing = ProductionClass()
... thing.method(1, 2, 3)
...
>>> mock_method.assert_called_once_with(1, 2, 3)
mock and unittest Module
Adding "patch" decorators to many methods can become cumbersome. For Python 2.6 or more recent you can use patch (in all its various forms) as a class decorator. This applies the patches to all test methods on the class:
>>> @patch('mymodule.SomeClass')
... class MyTest(TestCase):
...
... def test_one(self, MockSomeClass):
... self.assertTrue(mymodule.SomeClass is MockSomeClass)
...
... def test_two(self, MockSomeClass):
... self.assertTrue(mymodule.SomeClass is MockSomeClass)
...
... def not_a_test(self):
... return 'something'
...
>>> MyTest('test_one').test_one()
>>> MyTest('test_two').test_two()
>>> MyTest('test_two').not_a_test()
'something'
mock and unittest Module
An alternative way of managing patches is to use the patch methods: start and stop. These allow you to move the patching into your setUp and tearDown methods.
>>> class MyTest(TestCase):
... def setUp(self):
... self.patcher = patch('mymodule.foo')
... self.mock_foo = self.patcher.start()
...
... def test_foo(self):
... self.assertTrue(mymodule.foo is self.mock_foo)
...
... def tearDown(self):
... self.patcher.stop()
...
>>> MyTest('test_foo').run()
WSGI
- Web Server Gateway Interface (PEP333)
- Standardized interface to web app server to allow portability of apps
- WSGI app is a callable with parameters for environment dictionary and a callback function that sets HTTP response code and headers
- WSGI server simply calls the WSGI app and waits for completion, then returns the response to the client
- Almost all python app servers and apps are WSGI compliant
ReST API's
- Exposes resources with a lightweight service architecture
- An architecture, not a standard
- Multiple "maturity" levels (Richardson)
Level0 ReST
- Uses a single URI to access resource
- Tunnels an opaque payload
- Frequently uses a non-static name as part of URI e.g. a procedure-like name
- Receiver returns an opaque payload for application-specific interpretation
- Uses only minimal transport verbs (usually just GET or POST if HTTP)
Level1 ReST
- Similar to Level0 but uses multiple URI's to access resource
- Each URI reveals a separate element of the resource
Level2 ReST
- Frequently referred to as the "CRUD" level
- Mapped to GET, POST, PUT, DELETE (if using HTTP)
- Uses more facilities of the transport layer:
- HTTP headers for meta information
- HTTP response codes
Level3 ReST
- Highest level
- Level3 + uses a noun for URI base
- Implements HATEOS (Hypermedia As The Engine Of Application State)
- HATEOS provides an application-driven protocol using meta data for dynamic "next step" selection

--- layout: main title: "About Me" description: "" group: navigation ---
I entered the United States Army when I was 17 as a 98G Cryptolinguist. I was assigned to the Korean Language and spent the next year and a half learning Korean to a level of functional fluency. I graduated the course and received my Associates of Arts in Korean Language from the Defense Language Institute. Following language training, one of the most difficult courses I will ever have to take, I began work with the a joint-service team working for the National Security Agency. I was only able to be an intelligence analyst, the original job I enlisted for, for a short while. Shortly after beginning work with the Agency, my aptitude for software development was recognized and I was recruited to be on a software development team to build database-driven web applications for analysts.
I was in the military for a total of seven years and worked for the National Security Agency for the last 4 and a half years of my term. For my contributions to software development and enhancement to the various missions I was able to work on or for, I was awarded the Joint Service Commendation Medal by the National Security Agency and the Department of Defense.
Since my work for the government I have held positions doing large dataset cloud analytics using Java frameworks such as Hadoop, Cloudbase and HBase and for the past few years I have focused my career on Ruby on Rails applications and front-end development for javascript heavy applications built to utilize HTML5, CSS3 and modern javascript techniques.
Aside from all of my professional endeavors, I have a 9-year-old daughter and a wife from Melbourne, Australia. I love learning new things all the time. In the past few years I've applied my logical approach to problems to cooking and I love it. Despite what most people say, I think cooking is easy and just like building a lego set -- follow the directions. I also have a passion for movies. I worked as a writer and editor for TheFilmStage.com and covered film festivals as a film journalist writing film reviews and news. I like to keep my interests varied and unique.

While meandering around my local department store, I spotted a seed rack with some Heavenly Blue Morning Glory seeds. Hearing and reading about the LSA chemical in the seeds I decided it would definitely be a wise investment. So I bought five 1.8 gram packages and took them home.
Upon arrival, I took the seeds out of their packages and let them sit in a mixture of a very small amount of dish soap and about a cup of water. I was not too sure about pesticides or other factors and thought this to be a wise idea. After a day I let the seeds dry for a day. Once they were dry I put them back in their packages and rolled up them up tightly. The same could be done by wrapping them in a thick magazine cover or other such material. While wrapped, I took a hammer and pounded on each pack about a dozen times on each side.
When the seeds were crushed to my satisfaction I fed the debris through a window screen. I did this because I had read that the black coats made one very sick and the active ingredient was inside the seeds anyway. So, with the yellowish white powder sifting through and the black coats staying on top I created a pile of just the good stuff. I mixed this powder with some water and drank it down. It didn't taste too bad but made me sort of gag for one reason or another. Therefore, a separate glass of water to chase it down would not be a bad idea.
About a half an hour later I experienced very mild nausea, almost unnoticeable; nothing like the extreme diarrhea that I have heard about that comes after morning glory seed ingestion. So, I made use of the substance that has been used for nausea for thousands of years: Cannabis Sativa. After maybe four or five hits, I barely caught a vibe, but sure enough my stomach felt very settled and I felt very nice.
After I was done smoking I settled down to listen to some Medeski, Martin and Wood tunes and closed my eyes for 45 minutes or so without sleeping and got up to change the CD. After standing, I was very well aware that 'something' was going on. Just a slight change in perception, nothing too noticeable. So, I kind of chilled out for a while with this strange sort of buzz that soon climaxed into the peak of a trip approximately two hours after ingestion. This trip felt very natural and almost kind of chilled out. I was grooving to some Allman Brothers and watching the walls wave and flow to an extreme like I'd never seen before while this calm and collected.
 Motion was frame-by-frame, but flowing in my head at the same time. I couldn't help but to get up and dance to the music playing. I could hear several melodies emerging that I had never heard before and every note of it sounded amazing. I got totally lost in the music and my dancing and I must have been grooving for at least an hour (the Allman Brothers have some fairly lengthy jams). Exhausted as I was now, I laid down on my bed and drank some water. Without thinking about it I took the cap off the bottle and started chewing on it. After this point there isn't too much to recap (no pun intended), because I pretty much just laid on my bed and chewed on the cap for about 4 hours and stared at the ceiling letting random thoughts run through my mind. The bottle cap felt more than good to chew on, it felt great. I savored this white piece of plastic for hours, for a reason I cannot explain.
I don't remember too much after the bottle cap, except that I felt chilled out enough to go to sleep; which I've never done before while tripping. I woke up the next day feeling fine and almost refreshed. I was quite impressed with the turnout of the trip and the fact that I had a full-blown experience with almost no amount of nausea. I attribute this to my screening method and the cannabis. I would, however, recommend a smaller dose for those experimenting with this the first time. Three packs or 5.4 grams would probably be a good stepping stone to larger trips and deeper exploration. Have fun, and be careful.

Colored marbles are hidden behind some of the cells in the grid below.
Move the top right corner of the rectangle so that it contains exactly 2 marbles of each color. You can click on a cell to move the corner to that cell.
On the right side of the grid, the number of marbles of each color in the rectangle is displayed.
Note : in the final version, the goal will be to minimize the number of clicks. You can restart at any time to try to improve your score, but then the marbles change their positions. The positions of the marbles will actually be set while you click, so that you can't just be lucky.
To find the correct rectangle with a small number of steps, a strategy, or algorithm was needed. A good algorithm in this case, was to start from the top-left corner of the grid.
At each step :
With this method, you are guaranteed to find the solution, sice for each height, you will find the widest rectangle that doesn't have more than 2 marbles of each type. If there is a solution, it will be one of these.
To solve this task and get a good score, it was necessary to invent an algorithm, and apply it on the grid.
One possible algorithm, explained in the solution, corresponds to a 2D sliding window. A sliding window algorithm is an algorithm that is often used when you are looking for an interval of positions on an axis, such that the content of the interval satisfies some constraints and/or maximizes (or minimizes) some value. The idea is to move the beginning of the interval step by step, and at each step, increase the end of the interval until a constraint is broken.
In this case, it is a 2D sliding window in the sense that the beginning and end of the interval are represented on 2 different axis.


Despite the copious amount of information available concerning the toxicity and fatality of this plant, (and others of it's kind) it seems that there are those who still view nightshade as some sort of recreational joyride. It is NOT. It is an entity unto itself, and it's Saturnian nature will test those foolhardy enough to trifle with it within an inch of their lives.
My personal experience with it has never been of the aforementioned nature as I have taken the utmost care and respect when using this Herb. Therefore this is not so much a submission of my experience as it is a list of guidelines for the responsible use of belladonna.
 What you may at first perceive as a lack of effect is quite possibly a trick. This plant has many.
3.Belladonna tends to have a cumulative affect also adding to the danger of overdose. Therefore a serious time commitment is needed to avoid a negative experience.
4.Belladonna should be taken slowly and allowed to build up slowly so that a symbiotic relationship may be established with the plant.
5.An inability to perceive Belladonna's affect at first is normal. Chances are you are experiencing it, but it's early effects have come on so furtively that you cannot at first perceive your altered reality. Rest assured you will. I find that I experience a single point of memory compression, which allows me to re-analyze the experience and pinpoint my entrance point to the land of the dead.
6.If you are using this plant for the first time I recommend using the leaves rather than the berries as the leaves usually contain a more regulated amount of poison. My experience with a berry tincture is usually more intense.
7.STAY HYDRATED-this plant will dehydrate you
8.Have a baby-sitter for the first time. No really.
RECOMMENDED DOSAGES:
Dried leaf 1/2-2 ounces (do not exceed)
Berry tincture 1-15 drops (I start with 5)
I do not recomment eating the berries raw.

Jeff’s solution was to inline-block the whole list. That keeps the list only as wide as the natural width of the content, allowing the bullets to leave the left edge and travel with the centered content. As long as there are block-level elements before and after, that is a good solution. By way of an alternative, if the goal is to shrink the width of the list to the width of the content, that could also be achieved like this without stopping the list from being block-level:

Usually when I'm high I come online and read through some of the experience reports. I always think to myself that I should write one except for the fact I have never really had a truly exceptional high, until now.  I am writing this report about 45 minutes after I finished smoking it, and still on a good high :) I have been using crystal for about the past 10 months, on and off, sometimes I will use it 3 or 4 times in a week, sometimes I will go for a month without even touching it. I have of course been using weed since high school (haven't we all lol), and have use extacy and ghb on occasion.
Anyways, I hadn't used meth for about a week prior to this experience and I was kind of looking forward to getting high, as I had just bought a glass bulb pipe the day before. This was my first real time smoking meth, a while back I had taken a few hits from a pipe after I was already high from snorting, but didn't really feel anything, ever since I have always snorted it. Usually to get a good high going when I snort I use about 2 or 3 fat lines.
I got home around 1:20p.m. and got out my stash of crystal, my lighter, and my new pipe and sat down at my dining table. I usually get high with friends before going to a party or sometimes I snort a line or two before heading out to the gym. Today I had no plans and my mom wasn't coming home from work for a few hours so I thought I'd try and see just how high I could actually get from it. I took out a medium sized crystal, what I guessed would have been about 3 medium-large lines if I had snorted it and put it through the hole in the top of the pipe. I lit up and took a big hit, which I held in my lungs for about 30 seconds or so.
I repeated this maybe half a dozen times and perhaps I wasn't getting enough smoke, because I went through the first crystal and smoked up its residue as well, and had a nice high going but wasn't really getting the 'rush' everyone talks about. A slight tingly feeling had started to occur but nothing unlike what I've felt from snorting the same amount. I already had it in my head that I wanted to get really high and of course once I reach that point there's no stopping me :) I took out another crystal, this one almost twice the size of the first one and put it in the pipe. After a few big hits, most of it had liquified.
At this point I took out another crystal and crushed it up to make two medium sized lines, which I snorted. The next hit I took from the pipe I held in about 30 or 40 seconds and when I slowly blew it out, this intense warm rush of euphoria washed over my whole body. I have never felt anything like it and with each breath I took in and out another wave enveloped me. This continued through the end of the second crystal that I was smoking. Now usually to get a feeling like I had right then would have been more than enough, but I took out another crystal, this one so large I had to break it up in 3 pieces to get it through the hole in the top of the pipe. I glanced over at the clock for a second and was shocked. I had already been smoking for 50 minutes!
It felt for a second like I lost track of time, and each breath I took this rush of pleasure kept coming over me. I was starting not to care about anything except the rush. I started smoking the third crystal and each time I took a hit the feeling became more and more intense. Each time I held in the smoke and then blew it out, it became more and more intense. I thought I should write this report while I'm still high from it :) so that I could better describe what the feeling was like, but to put it into words is still hard. I was savoring each hit and between hits my body would start to sway and the warm rushes I felt were incredible, it was the best feeling I have ever had from anything, any drug, sex, anything. I am a very strong willed person who always looked down upon addicts, but at this moment I realized why a person would become addicted.
I don't know why but I felt the need to start softly talking out loud as I was swaying back and forth. I kept saying in this really slow, faded sounding voice 'This feels so good oh my god.' and each time after I said it I would take a breath and exhale and the waves would become even more intense. I have had some really good highs before on weed, exstacy, ghb, and of course crystal, but none that even came close to what I was feeling. My 'good' highs before on meth had come after snorting maybe 5 lines instead of the usual 3, but this high was completely different. Usually I become full of energy and feel like I can do anything when I snort a few lines of meth, but I have never felt a euphoria like this one.
Another point I think I should mention is that when I get high on anything, I usually stay fairly grounded in reality, while at the same time enjoying the high. I think the reason for this is that I'm very self aware, but this high was different. For a few minutes I completely lost myself in its warmth, feeling completely happy, very aware of things but at the same time very chilled out, almost like a perfect high on some really good herb combined with a perfect high from snorting, magnified 10 times over, but with the warm rushes and incredible intense feeling of pleasure, to compare it to any previous high I've had from snorting or smoking weed would not even begin to come close. I wasn't extremely energized like I usually am, all I wanted to do was just sit back and lose myself in this high's exquisite pleasure.
As I finished off the last of the third crystal, I realized there was a large amount of residue still in the pipe. At this point, although I was still very high, it crossed my mind to look at the clock, for I had started at 1:30 and my mom gets home at 4, so I wanted to make sure I'd have time to clean up and spray some air freshener before she got back. When I looked at the clock it was 2:45. I had been smoking for an hour and 15 minutes! It felt like only seconds since I started, I started to think that maybe I should start cleaning up because it might take me a while in the state I was in, but all I wanted to do was bring my high further along.
I started lighting up the residue in the pipe and took a hit. As I breathed out, I felt the most incredible rush yet of the session, my whole body and face started to sway back and forth as I whispered out loud how much pleasure I was in. At this point I started to have trouble controlling my movements and I dropped the pipe on the table where the bulb part of it shattered, making a mess all over the table. I thought for a second that this would end my experience, but then I looked at the stem of the pipe, still intact, and still filled with residue. After about 3 more large hits, my lighter completely ran out of fluid! Even with some of my marathon weed sessions with a friend, that has never happened.
I drifted out of consciousness again for a few seconds, as with each breath the warm rush of euphoria continued to course through my body. I wish I could explain this better, but the pleasure I felt is indescribable, no matter what words I use, as I read back through it, they don't fully capture the intensity of the experience. It felt like I was in heaven and experiencing a world of warmth and pleasure that I never imagined existed. It continues to amaze me how different this high was from snorting. If I had snorted the amount that I just smoked, I would have had the energy to run a marathon for days, lol. This high was unlike any high I've had from meth, or anything else, ever. Although when I snort it, I do get a bit of a rush it was nothing even close to what I felt this time.
After sitting at my table for a few minutes after the lighter ran dry, pondering what had just happened to me, and if I had learned anything about myself from it, as I always do during and after a high on anything, I came to the conclusion that I hadn't really discovered anything, all my energy was concentrated on feeling the magnitude of this incredible high, I hadn't even a chance to introspectively look at myself. I chuckled at this thought, thinking for a minute that this is what an addict must feel like. I am disciplined enough not to allow myself to become addicted to a drug, whenever I begin to think I am using too much, I take a few days off to let my body recover, but this high did show me the power that a drug like meth can have over someone.
I am not planning on smoking that much again for a long ass time because I don't want to build a tolerance to it, but for a few seconds at the end of my session when I was thinking about it and still enjoying the feeling, I felt like I would do anything to stay in a state of such bliss. A last thing about this high that was different from my previous highs, is that about 15 minutes after I finished smoking, the warm rushes were almost gone, and I was actually not nearly as energetic as I would have been if I had snorted say 3 or 4 lines. And I went through nearly 1/2 a gram.
From my experience it seems that smoking produces an incredible rush, although the high after the rush is not as fun as it is with snorting. Snorting, however doesn't really produce that much of a completely euphoric effect, more of an all around sense of well being. Anyways, having thought about all this for a while, I finally got up from the table and went about cleaning up the mess I had made. I washed my hands when I was done and I looked at my right thumb, which was almost rubbed raw from flicking the lighter so much. While I was high, I didn't even feel it.
All in all I'm very glad I had this experience, as I would go as far to say that it was really the best feeling of my life. It seems to me that is a bit pathetic to make a statement like that, but I am simply giving as honest a description as I can. As I'm writing this, I am thinking of how I will describe it to my best friend, whom I have shared some insane highs with, or if I will forgoe the description and tell him to just try it himself :) It was definitely a great experience, although not an overly productive one, and while it was fun, I do not plan on smoking that much meth again for a long time.

Stack
public class Stack: Container
The Stack
widget is a container which only shows one of its children at a
time. In contrast to Notebook
, Stack
does not provide a means for users
to change the visible child. Instead, the StackSwitcher
widget can be used

Transitions between pages can be animated as slides or fades. This can be
controlled with transitionType
property. These animations respect the
“gtk-enable-animations” setting.

Modern Abstract Spotlight: Chameleon by Logy Games
If you’re a fan of light chess variants and unique components, you’ll love Chameleon by Logy Games. Mitsuo Yamamoto is the designer behind the game and the company which produces these hand-made ceramic sets. At its core, Chameleon is a small chess game reduced to the movements of kings, knights and bishops. Every piece has a “nature” and can always move one space any direction like a king. The “nature” is essentially the middle color of each piece (black or white). This determines if a piece can move like a knight or bishop depending on what square it’s on.
The variable moves can be summed up with the following:
If the piece’s nature matches the square color, it moves like a bishop.
If the piece’s nature doesn’t match the square, it moves like a knight.
The goal is to either capture all your opponents pieces or move one of your pieces to the other side of the board without being captured on the next move.
I would highly recommend it to any fans of simple abstract strategy games. If you want to give it a try, it’s pretty easy to make your own version.
Here is also a print and play image that was made available on the Kickstarter campaign page.

Remember the quadratic formula? It looks something like this:
$fraction(-b+square_root(b^2-4ac), 2a)$
But that's just some expression. If you think a little harder, you might remember its immediate context and meaning: If you have three known quantites $a, b, c$ and some unknown $x$, but you know that $ax^2 + bx + c = 0$, then you can deduce the value of $x$--it is the expression you see above.
But when does that happen? Mathematics is always concerned with "finding $x$" almost as a game in its own right, but really the quest for $x$ most often starts with a real problem. Maybe we want to predict the motion of a canonball. We intuitively know the arc through the air resenbles a parabola, and maybe even remember that the quadratic equation above also looks like a parabola. So if we know some physics maybe we can model the canonball with a quadratic equation, whereupon this formula will let us deduce things about it's trajectory.
We start with a real-world problem, model it as a mathematical one, use mathematics to solve the model, and then interpret the results as predictions about the real world. In the case of the canonball, the mathematical model is an equation, and the mathematical technology that takes us through the bottom half of that picture is the quadratic formula.
This is not uncommon: An equation simply captures the numerical relationships between numbers. If we can solve equations, that simply means that we can deduce numerical consequences from these relationships. Scientific laws are often about relationships between measurable quanities--that is, equations. Applying scientific laws, then, is about deducing the consequences of those relationships in various specific situations. That is, solving equations.
The lowly quadratic formula makes a very brash claim, then: Any time you have a relationship between numbers that is quadratic, a single formula will furnish all the consequences of that relationship without exception. When we happen on something so powerful and striking, it is valuable to ask how this came about and how far we can push that mechanism to get even more powerful results.
This document will be a journey of thinking deeply about simple things. Broadly, the direction of this journey will be toward the generalisation of the quadratic formula to cubic equations: $ax^3 + bx^2 + cx + d$. However, the real goal is an effective understanding of equations of this kind, and the technology that helps to solve them not just numerically, but in a way that gives us a precise understanding of how those solutions depend on the situation we were given and change with it.
We will gently but unapologetically introduce abstractions from the field of abstract algebra when useful, and will equally unapologetically gloss over others. By the end, you will have exposure to high level ideas from group theory, discrete harmonic analysis, and Galois theory. Those names, however, will still more or less be just words, as that's all they ever really are.
Our goal is to solve the cubic equation $x^3 + bx^2 + cx + d = 0$ with rational coefficients. We will start by thinking about a simpler case: the quadratic formula. $x^2 + bx + c = 0$. Equivalently, if $x^2 + bx + c = (x-alpha()_1)(x-alpha()_2)$, we want an explicit formula for $alpha()_1$ and $alpha()_2$ in terms of $b$ and $c$ that uses only elementary operations (arithmetic operations and taking roots).
Let's start with an example: $x^2 + 1 = 0$. We know the solutions to this: $i$ and $-i$. In fact, we know a relationship between these two solutions: They are complex conjugates of another, which we will denote with a $tau$: $-i = tau(i)$. This is not a coincidence, but a result of the following observation: If we have a complex number $alpha()$ that is a root of this equation: $alpha()^2 + 1 = 0$, then we can take complex conjugates of both sides:
$tau(alpha()^2 + 1) = tau(0)$
Certainly $tau(0) = 0$, so the right side is easy to simplify. But the left side also simplifies: The important point is that with complex conjugation, it doesn't matter whether you first add two numbers and then conjugate them (like $tau(a+b)$) or conjugate them first and then add them (like $tau(a)+tau(b)$)--the result is the same: $tau(a+b) = tau(a)+tau(b)$. And similarly for multiplication.
This property is really quite rare in the world of mathematics: $square_root(1) + square_root(4)$ is 3, and not $square_root(5)$, $sin(pi())+sin(pi())$ is -2, and not $sin(2pi())$ (which is 0), and $1^2 + 2^2 = 5$ and not $3^2$. This property is also pretty rare in the real world: If you put on your socks and then your shoes, the result will be quite different to if you put on your shoes first and then your socks! When an operation can be done before or after both addition and multiplication with the same result, it is therefore quite special. Such operators are called "homomorphisms" (literally "same shape").
The fact that $tau()$ is a homomorphism allows us to rewrite the equation as
$tau(alpha())^2 + 1 = 0$
That is, $tau(alpha())$ is also a solution to $x^2 + 1 = 0$! This is a very general fact: If we have any polynomial $f(x)$ with rational coefficients, then $tau(f(alpha())) = f(tau(alpha()))$, so if $2+i$ is a root of $f(x)$, then you know immediately that so too is $2-i$.
Now let's take a different example: $x^2 - 2 = 0$. Any elementary student will tell you the solutions to this are $square_root(2)$ and $-square_root(2)$. However
We start with the $alpha()_1 = sig(alpha())$

M : You donot treat the computer as others do, you treat as if it were part of you, you talk to him and he answers, he explains and you understand better, and it has been happening for years .... ever wondered why? beacause you are not very much different from ur friend.

N : yes
M : you will have to let it go, you will have to let it all go anger fear doubt and disbelief, free your mind and your body would follow.
N : But you said i donot have one ...
M : oh i did??!! well thats true, but to get out, you must first convince yourself that you are very much inside.
N : It seems to me that you like to confuse people ...
M : I love to let them discover... Do you remember you poped when I had explained it to you.
N : Yeah it was too much for me...
M : thats the way for every body ..but your age was a challenge ..you were too old to get free. Didn't you see the other potentials? they were all kids. And that Mojo even called you a geriatric!!
N : Yeah! but why is age a problem, ...
M : the more you live the more you store the patterns the more logical you get
N : is logic bad?
M : it relies on probability, certainties and treats exceptions as aberrations.
N : so?
M : it is built on rules and thats what makes it weak
N : Quantum leaps are not an every day affair are they?
M : i guess not! they are rare specially in simulations where they are generally treated as bugs.
N : Is there a way out?
M : yes there is ... change the paradigm and frame of reference.
N : From ampliude to frequency, from knowledge to essence, from matter to mind ..isn't it?

M : yes but thats not enough, mind always tries to go back ..look at him .. he would one day ditch us. He is tired of this place, he is tired of fighting, tired of eating that God da.n goop every day. All the single cell protiens could not raise even a dendrite out his dead neurons.
N : (laughs) true! i don't like him myself.
M : it is not the question of likes and dislikes it is the question of beliefs and disbeliefs. Even after seeing the red petals growing from unfathomably large black stems, he wants to go back ..he believes in those pods and i believe in this hovercraft.
N : ethics are a tough science
M : yes they are ... however you cannot deny that you feel happy if you adhere to them. So do you still look at the woman in the red dress (squints)
N: (chuckles) well .. not quite!
M : look again ..pointing towards his back
N: (turns, expecting to see the same old sentient program aiming a 0.5AE at his forhead, but he has gone, instead there is nothing but light. Is it the "door" the door of light , brilliant flash of light is rising with power of billion suns , embracing in it everything that falls in way , its his turn now , unmindfully he streches open his arms in a desperate attempt to grasp all that he can, his jacket is flying with the air, he can not keep his wonderstruck eyes open for long they slowly close and lips go still but he is smiling, he mingles with light and soon there is only light that remains .. his friend smiles with the usual charisma and says"you deserved it" and departs)
A shreaking voice of some alarm cuts through the bliss ... and soon the trance ends, it is the same 101 and same old bed ... and yes its 9:18am again!

That is when it hit me — there could be a “global basis” for beauty, and it certainly was not one where “ethnic” beauty was going to be embraced in terms that I was comfortable with. Yes, while a range of skin colors is likely to be celebrated on billboards worldwide, there is less-than-desirable variability in the type of features being represented. In other words, the Asian model is still likely to have high cheek-bones and larger eyes, while the Black model is likely to have a thinner nose.
