Basic six steps to follow in any data science project
Before starting any data analysis tasks, we must have a clear goal about our results or output.We need to understand the data and problem to get meaningful results from our analysis.
Exploratory Data Analysis (EDA) phase of a data science project helps us to analyze our datasets, summarize their main characteristics, understand their variables and relationships between them, in order to formulate some sort of hypotheses. In this post, we will delve in important EDA techniques which are used by every data scientist/analyst.
Step 1 : Import all the required libraries.
We will import numpy and padas
#import the libraries
import numpy as np # we will use np as an alias for numpy
import pandas as pd # very well accepted alias for pandas is pd
Numpy: It is a fundamental tool for scientific computing. It has a very efficient array of operations and provided high-level mathematical functions. It is very good for homogeneous data types but in the real world, we have heterogeneous datasets( numerical as well as categorical features).
To tackle this heterogeneous dataset, we use pandas.
Pandas: is built on top of Numpy which allows operations on tabular data. The tabular data structure consists of rows and columns. In terms of pandas, we call it a data frame. On the data frame, we use different kinds of functions and joints.
In Pandas: Rows is an observation and column is features or attributes.
Step 2: Read the data
Once the data is imported, we will read the data in the data frame. In our case, we will read two excel files and load them into our data frame.
df_08 = pd.read_excel("data/all_alpha_08.xls", sheet_name=0)
Step 2.1 : Learn more about the data
Once we have data in our data frame, we will learn about the data by using some functions on it. Following functions are very common for this purpose.
-
head()
-
info()
-
duplicated()
-
describe()
-
how many rows have missing values
Pandas documentation is the best place to discover and understand these functions. For the sake of completing this course, I will copy and paste about them.
1. head()
DataFrame.head(n=5)1 returns the first n rows for the object based on position. It is useful for quickly testing if your object has the right type of data in it.
n: int, default 5
df_08.head()
2. info()
This method 2 prints information about a data frame including the index type and column types, non-null values and memory usage.
df_08.info()
3. duplicated()
Return 3 boolean Series denoting duplicate rows, optionally only considering certain columns. For finding the number of duplicated rows, we will use the sum function on the data frame.
example: sum(df_08.duplicated())
#no of duplicated rows in df_08
sum(df_08.duplicated())
4.describe()
Generate descriptive 4 statistics that summarize the central tendency, dispersion and shape of a dataset’s distribution, excluding NaN values.
df_08.describe()
5. Find how many rows have missing values
This function 5 takes a scalar or array-like object and indicates whether values are missing (NaN in numeric arrays, None or NaN in object arrays, NaT in datetimelike).
In order to find all the rows, which has missing values, we will do a sum over it, as shown below.
# numbers of rows which have missing values
sum(df_08.isnull().any(axis=1))
# nunique() returns number of unique elements in the object.
df_08.nunique()
Step 3 : Drop unnecessary columns
Drop all the unnecessary columns which we don’t need by using drop
function.
We use inplace=True
which tells the Dataframe, to copy the data frame back into the original df object.
df_08.drop(columns=["Stnd", "Underhood ID","FE Calc Appr","Unadj Cmb MPG"], inplace= True)
df_08.info()
Step 4: Rename all column labels to replace spaces with underscores and convert everything to lowercase(Underscores can be much easier to work with in Python than spaces).
Being consistent with lowercase and underscores also helps make column names easy to remember.
df_08.columns = df_08.columns.str.lower().str.replace(' ','_ ')
df_08.info()
Step 5 : Clean the data
There are three common things to do in this part.
1. Missing data
In every dataset, we have some missing values. It can be handled by imputing or removing them. Imputation is done by mean, median or backward or forward fill.
In case we are doing imputation, we use fillna
function on the data frame for filling the data.
For removing the data we use dropna()
on the dataset.
We will be just removing the missing values.
df_08.dropna(inplace=True)
2. Duplicates
As discussed earlier, there is a duplicated
function, for checking the duplicated rows. It show’s the result in True
or False
.
We can find the number of rows which are duplicated with the following command:
sum(df.duplicated())
In order to remove the duplicates we use
df_08.drop_duplicates(inplace=True)
print df_08.duplicated().sum()
The sum of duplicated
function is zero, which means there are no duplicates rows anymore.
df_08.info()
df_08.head()
In cyl
column, string is attached to the integer. The data is dirty, so we will extract the integer from it, with the following way.
# extract int from string.
df_08['cyl'] = df_08.cyl.str.extract(r'(\d+)', expand=True)
3. Incorrect data types:
There are scenarios when the rows are not in the same datatypes. For example, dates are in String type. It will be more convenient to work with the date datatypes. We can change the string datatypes to date datatypes by the following command.
df['timestamp'] = pd.to_datetime(df['timestamp'])
There are two types of data, numerical and categorical data. All the algorithms understand numerical data. All the data should be converted into numerical data. We need to change some of the data types to float or int.
We will change some of the datatype to float
datatypes.
# 2008: convert int to float.
df_08['air_pollution_score'] = df_08['air_pollution_score'].astype('float')
df_08[df_08['air_pollution_score'] =='6/6'].head()
As we can see, this row has two fuels “ethanol/gas” and its air_pollution_score is 6/6
. It would be better, if we create two different rows of these values by keeping the same values of the other columns.
# finding the number of rows which contains '/'.
sum(df_08['air_pollution_score'].str.contains('/'))
# copying the data which has two values into a new dataframe
double_fuel_08 = df_08[df_08['fuel'].str.contains('/')]
double_fuel_08_1 = double_fuel_08.copy()
double_fuel_08_2 = double_fuel_08.copy()
We will seperate columns which has two values in every rows and then split the data frame into two data frame to store two rows vlaues.
columns_to_split = ["fuel","air_pollution_score","city_mpg","hwy_mpg","cmb_mpg","greenhouse_gas_score"]
for col in columns_to_split:
double_fuel_08_1[col] = double_fuel_08_1[col].apply(lambda x: x.split("/")[0])
double_fuel_08_2[col] = double_fuel_08_2[col].apply(lambda x: x.split("/")[1])
Checking the data frame if it splitted in a desired way
double_fuel_08_2.head()
Now we will delete the rows which contains ‘/’ from double_fuel_08
and add two newly created data frame.
double_fuel_08.index
df_08.info()
Dropping the rows
df_08.drop(double_fuel_08.index, inplace=True)
df_08.info()
# checking all the rows which contains '/'
df_08[df_08['fuel'].str.contains('/')]
Appending the two data frame with two distinct values into one data frame.
rows = double_fuel_08_1.append(double_fuel_08_2)
rows.head()
df_08 = df_08.append(rows, ignore_index=True);
df_08.shape
3.1 Converting the rest of the columns into float
# convert object to float
df_08['air_pollution_score'] = df_08['air_pollution_score'].astype('float')
df_08['air_pollution_score'].dtype
column_list=['city_mpg', 'hwy_mpg', 'cmb_mpg','greenhouse_gas_score']
for col in column_list:
df_08[col] = df_08[col].astype('float64')
df_08.dtypes
Step 6: Exploring with Visuals
For numerical datatypes, to understand the variable visually is with a histogram. To get the histogram of a pandas series, we can use the hist method, as shown below.
df_08["cmb_mpg"].plot(kind="hist", title="combined mpg in 2008");
#Describe the correlation between displacement and combined mpg.
df_08['displ'].corr(df_08['cmb_mpg'])
Conclusion:
In this post, you learned about Exploratory data analysis(EDA) which is very important in every data science project. These basics steps should be mastered by a data analyst/scientist. As we can see, these steps are easy to remember and practice. Take a data set and practice this method to have more confidence. In case you are not able to remember, then there is no problem. You can always search and find their solutions. As I said in an earlier post, you should know how to find the solutions for problems as a data scientist/analyst. I hope, this helps and motivates you to explore more about EDA and other phases of a data science project.

Liverpool have employed Sam Allardyce’s former go-to psychologist Lee Richardson
by Biscan's BootsThere’s a mighty interesting interview with Jurgen Klopp by James Pearce in the Athletic at the moment, and we’d encourage you to give it a read.
The boss speaks in length about the current positivity in the club, how he has brought it about and why the players have to manage themselves as well as he does.
After all – there are 20-dd hours a day when they’re not training and he has no control!
The piece of news that is quite a revelation though is that Klopp hired a sport psychologist in the summer – who works casually at Melwood and is available to the players whenever they need him rather than anything more formal.
“Sports psychologist Lee Richardson has been working with the club’s players since July and has his own office at Melwood where he’s based for three days each week,” Pearce writes.
“The former Watford, Blackburn Rovers and Aberdeen midfielder was recruited from Hull City by Liverpool’s medical rehabilitation and performance manager Phil Jacobsen.
“Richardson had a brief stint in management with Chesterfield a decade ago before changing careers. He has previously been part of Sam Allardyce’s staff as psychologist for West Ham and then Crystal Palace.”
We think some will be shocked to hear a former backroom staffer to Allardyce was headhunted by Klopp – but the manager has brought in a whole host of specialists in certain fields over the past few years and perhaps the only surprise is that a sports psychologist wasn’t part of the team sooner.
Liverpool have a throw-in coach in Thomas Gronnemark, a nutritionist in Mona Nemmer and an expert sports scientist and fitness specialist in Andreas Kornmayer – to name but a few.
Klopp has never been arrogant enough to think he knows it all – which is part of the reason too why he was so happy to work with Michael Edwards and the scouts on transfers instead of having full authority.

1) Copying files between projects in the same solution within the IDE
DOES NOT ACTUALLY COPY the files. Any changes made to any of the "shortcuts"
will affect the file(s) that you were planning on not modifying. In order to copy the files you will need to do it with the actual file-system.
2) Even though VS2010 has installs the
<initializer_list>
header, it doesn't work and yields output similiar to this:
c:\program files\microsoft visual studio 10.0\vc\include\initializer_list(13): error C2143: syntax error : missing ';' before ''template<'' |
Microsoft says:
As you probably know, we license our C++ Standard Library implementation from Dinkumware, whose master sources target many compilers. When we updated our implementation to the latest version of their master sources, we picked up their support for initializer lists in addition to rvalue references, forward_list, and so forth. Because we decided against implementing initializer lists in the VC10 compiler (due to time constraints, we picked 6 Core Language features to implement in VC10), I stripped out the support for initializer lists that had made it into our headers (it was protected by a macro that was never defined). Unfortunately, I simply forgot that we had picked up <initializer_list> itself. Oops.


The Ti.Healthkit.Statistics class represents the result of calculating the minimum, maximum, average, or sum over a set of samples in the HealthKit store. HealthKit creates statistic objects using either a Ti.Healthkit.StatisticsQuery or a Ti.Healthkit.StatisticsCollectionQuery. For the statistics query, it performs the specified calculations over all the samples that match the query. For the statistics collection query, it partitions the matching samples into a set of time intervals and performs the calculations over each interval separately.
When requesting data from a statistics object, your request must match the options you used when creating the query. For example, if you create a query using the STATISTICS_OPTION_DISCRETE_AVERAGE option, you must access the results using the getAverageQuantity
method.
The start of the time period included in these statistics. (read-only)
This property contains the start date for the statistics. If you calculated these statistics using a statistics query, this is the earliest start date from all the samples that match the query. If you calculated these statistics using a statistics collection query, this is the start of the time interval for that particular collection of statistics.
The end of the time period included in these statistics. (read-only) This property contains the end date for the statistics. If you calculated these statistics using a statistics query, this is the latest end date from all the samples that match the query. If you calculated these statistics using a statistics collection query, this is the end of the time interval for that particular collection of statistics.
The quantity type of the samples used to calculate these statistics. (read-only)
The quantity type from the statistics query used to generate these statistics.
An array containing all the sources contributing to these statistics. (read-only)
Returns the average value from all the samples that match the query. If
the source
parameter is specified, only samples created by that source
are used.
Returns the maximum value from all the samples that match the query. If
the source
parameter is specified, only samples created by that source
are used.
Returns the minimum value from all the samples that match the query. If
the source
parameter is specified, only samples created by that source
are used.
Returns the sum all the samples that match the query. If
the source
parameter is specified, only samples created by that source
are used.


Entity references cannot be properly resolved as DTD part and all external stuff is completelly ignored. A callback interface can be established for this purpose:
public interface EntityReferenceResolver { NodeList resolveEntityReference(EntityReference ref) throws IOException; }
Attribute values should report DTD defined defaults as it cannot be also retrieved from token chain. In this case can be also introduced a callback or does not stay fully with DOM spec. But is it violation of spec? We are contruction DOM without DTD knowledge so there are not default attributes declared.

async-rx¶
Versions following Semantic Versioning
Overview¶
A free implementation of “rx” alias “react” alias “the power of observable pattern and his children” for application server side.
Implementation is based on:
async function with curio framework
user Protocol declaration for type checking
our friends: poetry, flake8, black, isort, pytest, mypy, sphinx, tox, travis …
a taste of namedtuple
a lot of closed variable, clojure function, inner function
a taste of curiosity
shake it, again a little bit and tadaa !
Installation¶
Install this library directly into an activated virtual environment:
$ pip install async-rx
or add it to your Poetry project:
$ poetry add async-rx
Note about Python version support:
python code and test use python 3.8+
typing extensions give us an optional python < 3.8 support
API and Usage¶
After installation, the package can imported:
$ python
>>> import async_rx
>>> async_rx.__version__

A short sample¶
With this amazing observer:
class ObserverCounterCollector:
def __init__(self):
self.on_next_count = 0
self.on_completed_count = 0
self.on_error_count = 0
self.items: Any = list([]) # a bad idea isn't it
async def on_next(self, item: Any) -> None:
"""Process item."""
self.items.append(item)
self.on_next_count += 1
async def on_completed(self) -> None:
"""Signal completion of this observable."""
self.on_completed_count += 1
async def on_error(self, err: Any) -> None:
self.on_error_count += 1
We will going to select odd number:
async def _predicate(item: int) -> bool:
return item % 2 == 0
seeker = ObserverCounterCollector()
observable = rx_range(start=0, stop=100) # create an observable of [0, 1, ..., 99]
sub = await rx_filter(observable=observable, predicate=_predicate).subscribe(an_observer=seeker) # filter and subscribe
sub() # release resource
# we have :
assert seeker.on_next_count == 50
assert seeker.on_completed_count == 1
assert seeker.on_error_count == 0
assert seeker.items[0:6] == [0, 2, 4, 6, 8, 10]
Your new on react/rx and wanna taste it ?¶
First question: Where to begin ?
If you read this page, you probably ever doing lot of search on google & co, and probably loose as me about react component in html/js/whatever. I can’t purpose your the best state of the explanation, but… AMHPOV, if you like to known how slug are done behind the scene, you should remember:
what is Observable pattern (or listener, alias callback)
what is an event emiter (something which send event ?)
ok, with this in mind:
an observer receive event from an observable when he subscribe on it
events are “on_next(item)”, “on_completed()”, and … “on_error(err)”
Take a look in “protocole.py” and come back :)
Did you see Observer/Observable/XXXHandler/Subscribe ? And Subcription (yes it will called for unsubscribe) ?
So rx_from([1, 2, ...])
create an observable which will send items of list in sequence when an observer subscribe on it.
Take time to look at test unit :)
You can go into observable module and see all rx_from, rx_defer, rx_last, …
But but but, what is a freaking “subject” ?
It’s like an observer AND an observable which can multicast items from an observable to several observers. As it is an observer, it can receive data from somewhere. As it is an observable, observer can subscribe on it.
Take a look under subject module and test unit, see what is a replay_subject, funny no ? See the function subject.

Its like a subject which you can connect/disconnect as you want or automatically (with a call on ref_count). “connect” mean that subject start to receive from observable, so items will be send on observers.
I hope this could help you a little bit :)

This site is made using Jekyll, hosted on github pages and the theme started as Akshay Argayl’s Jekyll Mono Theme, but has been altered a bit.
Picking colors has always been a bit of a mystery to me, so I used pictalicious and palletton to try to do so somewhat scientifically.


Blog Entry
An important part of creating a webpage is placing each piece (or element) of your webpage in the correct spot. You wouldn’t want text boxes to overlap with images or even an image next to a text box, when it’s actually suppose to be placed above the text box. In CSS we call this positioning and it’s exactly what it sounds like. There are different ways to control the positioning of elements on a webpage and one of the most important ones uses the display property. To understand the display property in CSS, it’s important to picture each element on a webpage as a box. So, when you use the display property to adjust the position of an element, whether its text or an image, think of it like you are positioning the box that the element sits in.
Two important values of the display property are, block and inline-block . When you give an element the property of block, the element is set to take up the entire width of a screen. Therefore, the only open location for other elements to take would be the space above and below. When an element is set to inline-block, the element retains the block shape but will now default to sitting next to (or inline) with the other elements.
In the first example that I’ve included below you will see each element with the value: block. Even though it looks like you could fit more than one element next to each other, using block stacks the elements on top of one another. On the right side of the image, you will see the CSS coding that gives the element div a display of block.
In the second example, you will see the elements with a display value of inline-block. Instead of being stacked up on top of each other, they are laying on the same line in the webpage. On the right of the image, you will notice that all of the elements have been given a display value of inline-block.


UDecide Sri Lanka was established in 2018. It is the first of its kind in Sri Lanka and is driven by an energetic and diverse group of individuals for the purpose of promoting the practice and use of mediation among diverse groups in Sri Lanka, including students, undergraduates and professionals in the commercial and industrial sectors of the country. UDecide believes problems should be solved by the parties themselves, in a manner that is beneficial to everyone. This is only possible through Mediation. The current justice system is adversarial, where relationships rarely survive a dispute. UDecide wishes to change this, and connects with schools, universities and corporations to conduct awareness and training programs regarding the importance of amicable and mutually beneficial conflict resolution. In addition to this, as a Mediation platform, UDecide provides services and assistance to anyone who wishes to solve their disputes in an effective manner.
We conduct awareness Raising workshops in schools, universities, teacher training colleges and cooperate entities, with a view to promote mediation practice and use of mediation among all sectors of the community as a mode of amicable, efficient and effective dispute resolution.
We conduct professional mediator training programmes in partnership with international training institutes, for professionals aspiring to become mediators.
We conduct peer mediator training programmes for school students and university undergraduates, in order to promote mediation as an amicable and effective dispute resolution mechanism in schools and universities, while sharing the concept that peers can empower each other through mediation. Project Peer Power is specially designed for this purpose, where students are trained through the Peer Mediators Hub and continuously guided and supervised by us, UDecideSL.

--- layout: post title: ! 'Rails 2.0.4: Maintenance release' categories: - releases author: David published: true date: 2008-09-03 09:43:00.000000000 +01:00 ---
Thanks to Git it’s been a lot easier to maintain older branches of the code base, so we’ve taken the opportunity to backport a bunch of bug fixes to the 2.0 branch and here’s the release for that.
The only major issue is that we’ve fixed the REXML DoS vulnerability with a monkey patch that ships in the box. So if you’re on 2.0 and haven’t dealt with the issue already, you can upgrade to 2.0.4 and get it fixed.
You can install with: gem install rails --version 2.0.4
UPDATE: The actual 2.0.4 gem didn’t get published yesterday due to a bug in the release script. It’s been fixed and 2.0.4 is actually available on the main gem repository. Sorry about that!

Kanye West’s Sunday Service teams with Joel Osteen’s megachurch
by Sara DornChristianity will get a star-powered boost from two of the religion’s most famous disciples — when Kanye West’s Sunday Service comes to Joel Osteen’s Lakewood Church.
Osteen will interview the rapper-turned-evangelist Sunday at his 17,000-seat megachurch in Houston, a church representative told the Houston Chronicle.
The interview will air live on Sirius XM at 11 a.m. West will return at 7 p.m. for a performance with his gospel choir.
The rapper began dabbling in the religious arena earlier this year with his pop-up choir performances. The “Sunday Services” feature only music, and no preaching, but have a “Christian vibe,” West’s wife, Kim Kardashian, said in an April interview with Elle magazine.
West is currently promoting his new album, “Jesus is King.”
The flamboyant televangelist is expected to ask him about his “journey to his faith” in the 15-20 minute Q&A, Lakewood representative Donald Iloff told the Chronicle.
“Kanye and Joel are friends,” Iloff said. “He’s been wanting to come out for some time and it just worked out for this weekend.”

I’m currently a graduate student at the University of Illinois at Urbana-Champaign where I’m pursuing a doctorate in Informatics with a focus in Spatial Informatics. At UIUC I work as a research assistant under Dr. Shaowen Wang at the CyberInfrastructure & Geospatial Information Laboratory (CIGI) and CyberGIS Center for Advanced Digital and Spatial Studies. In these labs, I am part of the “Algorithms & Systems” and “Spatial Modeling” groups which allows me to explore deploying complex systems on Kubernetes and simulating complex socio-economic phenomena.
I have an interdisciplinary background which includes a Bachelors in Mathematics and Financial Economics with Honors in Computer Science and Math. This interdisciplinary undergrad from a liberal arts institution is now being supplemented by an intersectional graduate program that fits my research interests perfectly. I’m passionate about solving complex, data-driven, socio-economic problems involving space and connectivity, spurred on by an interest in graph theory and topology.
Some cool stuff I’ve been a (small) part of:

Create Exe from a Java Project with Many Jars Included
With 3 steps you can easily create an exe file from your project that may have many included jar libraries (mine had 14 jars). I used Netbeans 8.0.2, lauch4j 3.16, and Linux Netrunner 14 for this process.
1) Create your xml file with launch4j: It is required on the build level and will be done only one time. Simple details will be enough like min jre level and name etc.Here what I use as xml file for launch4j.It just takes icon file and min jre.
Create a folder and name it misc under your project folder (Mine is /home/mstf/NetbeansProjects/MyProject/misc).Your one jar file will be exported to exe folder ( which you don’t have to create since it will be created automatically) and put this temporary xml to misc folder with the name l4j-myapp.xml
2) Add a new build target to your build.xml to run Launch4j automatically.It can found under your project on the Files tab.
Open build.xml and add these target code before the </project> closing. You need to update your lauch4j folder by using location after the <property name=”launch4jexe.dir” tag. Also you can give any name to your one jar output file but it is not important.Save the build.xml file and close it.
3) The last step is creating your exe. Now again using the same Files tab click right on the build.xml and click on Run Target -> Other Targets -> package-for-lauch4j
Compile output will be like this and if there is no error you can get your exe under exe folder.


ONE HUNDRED AND ONE DALMATIANS (1961) A film review by Steve Rhodes Copyright 1996 Steve Rhodes
RATING (0 TO ****): *** 1/2
Since it is just slightly less than 101 days until the opening of the live action remake (with Glenn Close, Jeff Daniels, Joan Plowright and Joely Richardson) of Disney's 1961 classic ONE HUNDRED AND ONE DALMATIANS, we decided to watch the original cartoon version. What fun it is.
As the show starts, a Dalmatian named Pongo (voice by Rod Taylor) is contemplating ways to play matchmaker with his happy but recluse owner and song writer, Roger Radcliff (voice by Ben Wright). He does this by looking for a woman with a female dog heading for the park. After rejecting several unacceptable ones, he finds Anita (voice by Lisa Davis) and her Dalmatian Purdy (voice by Cate Bauer). As one of many delightful little aspects of the film, notice how the owners and their dogs look so much alike.
Soon Anita and Roger are married, but in a twist it is the dogs who are expecting. Into their happy life comes hyper-evil Cruella De Vil (voice by Betty Lou Gerson). She is a classic cartoon figure of a villain - very exaggerated, but effective. She is as thin as a rail, but wears an extra thick fur coat. She has hair that is half black and half white, and she smokes mile long cigarettes in a cigarette holder. Although she could make great anti-smoking ads, here her evil is manifested in her obsession for animal furs. When she demands to know when the pups will arrive, everyone is on their guard. Soon over a dozen pups arrive and are they ever cute.
The drawing for the picture is a blend of the real and the romantic. Indoor scenes are highly detailed, but the outdoor scenes have the look of a kid's storybook with the windows and doors lit up. The music (George Bruns) and songs are tuneful, but not memorable which works with lightheartedness of the script by Bill Peet, which is based on a book by Dodie Smith.
What is special about the movie are the small scenes. My favorite has all of the pups watching a black and white TV show about a cowboy and a dog. The pups are fascinated by it much as a human child would be. The most precious part is the plethora of little wagging tails.
The tension in the story is supplied by a pair of bungling dognappers named Horace (voice by Frederick Worlock) and Jasper (voice by Pat O'Malley). Cruella employs them to steal Dalmatian pups from all over town, and they end up getting ninety-nine of them including Pongo and Purdy's. There is another delightful scene where the bad guys and the pups watch Sunday's episode of "What's My Crime?" Perhaps those of you too young to remember "What's My Line?" will not be quite so enchanted by it as I was, but it is a cute scene.
Soon Pongo and Purdy use that time honored tradition of "the barking chain" to find where their pups are hidden.
ONE HUNDRED AND ONE DALMATIANS is not great drama, but it is a children's story well told. It should delight people of all ages. >From start to finish it is a very sweet show.
ONE HUNDRED AND ONE DALMATIANS runs just 1:29. It is rated G, and there is nothing to offend or scare anyone of any age - a great piece of family entertainment. Jeffrey (age 7) loved it as did I. I recommend it to you strongly and give the picture *** 1/2.
**** = One of the top few films of this or any year. A must see film. *** = Excellent show. Look for it. ** = Average movie. Kind of enjoyable. * = Poor show.  Totally unbearable.

Stream is a Duplex stream
subclass that implements the HTTP/2 Stream
concept. It has two 'sides': one that is used by the user to send/receive data (the stream
object itself) and one that is used by a Connection to read/write frames to/from the other peer
(stream.upstream
).
var Duplex = require('stream').Duplex;
exports.Stream = Stream;
Event: 'headers' (headers): signals incoming headers
Event: 'promise' (stream, headers): signals an incoming push promise
Event: 'error' (type): signals an error
headers(headers, [priority]): send headers
promise(stream, headers): promise a stream
reset(error): reset the stream with an error code
upstream: a Flow that is used by the parent connection to write/read frames that are to be sent/arrived to/from the peer and are related to this stream.
Headers are always in the regular node.js header format.
The main aspects of managing the stream are:
function Stream(log) {
Duplex.call(this);
this._log = (log || logging.root).child({ component: 'stream' });
this._initializeManagement();
this._initializeDataFlow();
this._initializeState();
}
Stream.prototype = Object.create(Duplex.prototype, { constructor: { value: Stream } });
PUSH_PROMISE and HEADERS are forwarded to the user through events. When error happens, we first close the stream.
Stream.prototype._initializeManagement = function _initializeManagement() {
this.on('PUSH_PROMISE', function(frame) {
this.emit('promise', frame.promised_stream, frame.headers);
});
this.on('HEADERS', function(frame) {
this.priority = frame.priority;
this.emit('headers', frame.headers);
});
};
For sending management frames, the this.upstream.push(frame)
method is used. It notifies the
state management code about the sent frames (using the 'sending' event) so we don't have to
manage state transitions here.
Stream.prototype.promise = function promise(stream, headers) {
stream.emit('promise_initiated');
this.upstream.push({
type: 'PUSH_PROMISE',
promised_stream: stream,
headers: headers
});
};
Stream.prototype.headers = function headers(headers, priority) {
this.upstream.push({
type: 'HEADERS',
priority: priority,
headers: headers
});
this.priority = priority;
};
Stream.prototype.reset = function reset(error) {
this.upstream.push({
type: 'RST_STREAM',
error: error
});
};
The incoming and the generated outgoing frames are received/transmitted on the this.upsteam
Flow. The Connection object instantiating the stream will read
and write frames to/from it. The stream itself is a regular Duplex stream, and is used by
the user to write or read the body of the request.

var Flow = require('./flow').Flow;
Stream.prototype._initializeDataFlow = function _initializeDataFlow() {
this.upstream = new Flow();
this.upstream._log = this._log;
this.upstream._send = this._send.bind(this);
this.upstream._receive = this._receive.bind(this);
this.upstream.on('sending', this.emit.bind(this, 'sending'));
this.upstream.on('receiving', this.emit.bind(this, 'receiving'));
this.upstream.on('error', this.emit.bind(this, 'error'));
this.on('finish', this._finishing);
};
The _receive
method (= upstream._receive
) gets called when there's an incoming frame.
Stream.prototype._receive = function _receive(frame, ready) {
this._log.debug({ frame: frame }, 'Receiving frame');
var callReady = true;
if (frame.type === 'DATA') {
var moreNeeded = this.push(frame.data);
if (!moreNeeded) {
this._receiveMore = ready;
callReady = false;
}
}
else {
this.emit(frame.type, frame);
}
if (frame.flags.END_STREAM) {
this.push(null);
}
if (callReady) {
ready();
}
};
The _read
method is called when the user side is ready to receive more data. If there's a
pending write on the upstream, then call its pending ready callback to receive more frames.
Stream.prototype._read = function _read() {
if (this._receiveMore) {
var receiveMore = this._receiveMore;
delete this._receiveMore;
receiveMore();
}
};
The write
method gets called when there's a write request from the user.
Stream.prototype._write = function _write(buffer, encoding, ready) {
var moreNeeded = this.upstream.push({
type: 'DATA',
data: buffer
});
if (moreNeeded) {
ready();
} else {
this._sendMore = ready;
}
};
The _send
(= upstream._send
) method is called when upstream is ready to receive more frames.
If there's a pending write on the user side, then call its pending ready callback to receive more
writes.
Stream.prototype._send = function _send() {
if (this._sendMore) {
var sendMore = this._sendMore;
delete this._sendMore;
sendMore();
}
};
When the stream is finishing (the user calls end()
on it), then we have to set the END_STREAM
flag on the last frame. If there's no frame in the queue, or if it doesn't support this flag,
then we create a 0 length DATA frame. We could do this all the time, but putting the flag on an
existing frame is a nice optimization.
var endFrame = {
type: 'DATA',
flags: { END_STREAM: true },
data: new Buffer(0)
};
Stream.prototype._finishing = function _finishing() {
delete endFrame.stream;
var lastFrame = this.upstream.getLastQueuedFrame();
if (lastFrame && ((lastFrame.type === 'DATA') || (lastFrame.type === 'HEADERS'))) {
this._log.trace({ frame: lastFrame }, 'Marking last frame with END_STREAM flag.');
lastFrame.flags.END_STREAM = true;
this._transition(true, endFrame);
} else {
this.upstream.push(endFrame);
}
};

Streams begin in the IDLE state and transitions happen when there's an incoming or outgoing frame
Stream.prototype._initializeState = function _initializeState() {
this.state = 'IDLE';
this._closedByPeer = false;
this.on('sending', this._transition.bind(this, true));
this.on('receiving', this._transition.bind(this, false));
};
Only _setState
should change this.state
directly. It also logs the state change and notifies
interested parties using the 'state', 'active' and 'inactive' event.
var ACTIVE_STATES = ['HALF_CLOSED_LOCAL', 'HALF_CLOSED_REMOTE', 'OPEN'];
Stream.prototype._setState = function transition(state) {
if (this.state !== state) {
this._log.debug({ from: this.state, to: state }, 'State transition');
var wasActive = (ACTIVE_STATES.indexOf(this.state) !== -1);
var isActive = (ACTIVE_STATES.indexOf(state) !== -1);
this.state = state;
this.emit('state', state);
if (!wasActive && isActive) {
this.emit('active');
} else if (wasActive && !isActive) {
this.emit('inactive');
}
}
};
_transition
is called every time there's an incoming or outgoing frame. It manages state
transitions, and detects stream errors. A stream error is always caused by a frame that is not
allowed in the current state.
Stream.prototype._transition = function transition(sending, frame) {
var receiving = !sending;
var error = undefined;
var DATA = false, HEADERS = false, PRIORITY = false, RST_STREAM = false, SETTINGS = false;
var PUSH_PROMISE = false, PING = false, GOAWAY = false, WINDOW_UPDATE = false;
switch(frame.type) {
case 'DATA' : DATA = true; break;
case 'HEADERS' : HEADERS = true; break;
case 'PRIORITY' : PRIORITY = true; break;
case 'RST_STREAM' : RST_STREAM = true; break;
case 'SETTINGS' : SETTINGS = true; break;
case 'PUSH_PROMISE' : PUSH_PROMISE = true; break;
case 'PING' : PING = true; break;
case 'GOAWAY' : GOAWAY = true; break;
case 'WINDOW_UPDATE': WINDOW_UPDATE = true; break;
}
switch (this.state) {
All streams start in the idle state. In this state, no frames have been exchanged.
When the HEADERS frame contains the END_STREAM flags, then two state transitions happen.
case 'IDLE':
if (HEADERS) {
this._setState('OPEN');
if (frame.flags.END_STREAM) {
this._setState(sending ? 'HALF_CLOSED_LOCAL' : 'HALF_CLOSED_REMOTE');
}
} else {
error = 'PROTOCOL_ERROR';
}
break;
A stream in the reserved (local) state is one that has been promised by sending a PUSH_PROMISE frame.
case 'RESERVED_LOCAL':
if (sending && HEADERS) {
this._setState('HALF_CLOSED_REMOTE');
} else if (RST_STREAM) {
this._setState('CLOSED');
} else if (receiving && PRIORITY) {
/* No state change */
} else {
error = 'PROTOCOL_ERROR';
}
break;
A stream in the reserved (remote) state has been reserved by a remote peer.
case 'RESERVED_REMOTE':
if (RST_STREAM) {
this._setState('CLOSED');
} else if (receiving && HEADERS) {
this._setState('HALF_CLOSED_LOCAL');
} else if (sending && PRIORITY) {
/* No state change */
} else {
error = 'PROTOCOL_ERROR';
}
break;
The open state is where both peers can send frames. In this state, sending peers observe advertised stream level flow control limits.
case 'OPEN':
if (frame.flags.END_STREAM) {
this._setState(sending ? 'HALF_CLOSED_LOCAL' : 'HALF_CLOSED_REMOTE');
} else if (RST_STREAM) {
this._setState('CLOSED');
} else {
/* No state change */
}
break;
A stream that is half closed (local) cannot be used for sending frames.
case 'HALF_CLOSED_LOCAL':
if (RST_STREAM || (receiving && frame.flags.END_STREAM)) {
this._setState('CLOSED');
} else if (receiving || (sending && (PRIORITY || WINDOW_UPDATE))) {
/* No state change */
} else {
error = 'PROTOCOL_ERROR';
}
break;
A stream that is half closed (remote) is no longer being used by the peer to send frames. In this state, an endpoint is no longer obligated to maintain a receiver flow control window if it performs flow control.
case 'HALF_CLOSED_REMOTE':
if (RST_STREAM || (sending && frame.flags.END_STREAM)) {
this._setState('CLOSED');
} else if (sending || (receiving && (WINDOW_UPDATE || PRIORITY))) {
/* No state change */
} else {
error = 'PROTOCOL_ERROR';
}
break;
The closed state is the terminal state.
case 'CLOSED':
if ((sending && RST_STREAM) || (receiving && !this._closedByPeer) ||
(receiving && (WINDOW_UPDATE || PRIORITY))) {
/* No state change */
} else {
error = 'STREAM_CLOSED';
}
break;
}
Noting that the connection was closed by the other endpoint. It may be important in edge cases. For example, when the peer tries to cancel a promised stream, but we already sent every data on it, then the stream is in CLOSED state, yet we want to ignore the incoming RST_STREAM.
if (receiving && (RST_STREAM || frame.flags.END_STREAM)) {
this._closedByPeer = true;
}
Sending/receiving a PUSH_PROMISE
if (PUSH_PROMISE && !error) {
assert(frame.promised_stream.state === 'IDLE', 'Promised stream is in invalid state (' +
frame.promised_stream.state + ')');
frame.promised_stream._setState(sending ? 'RESERVED_LOCAL' : 'RESERVED_REMOTE');
}
Common error handling.
if (error) {
var info = { error: error, frame: frame, state: this.state };
if (sending) {
this._log.error(info, 'Stream error: sending illegal frame.');
throw new Error('Sending illegal frame (' + frame.type + ') in ' + this.state + ' state.');
}
reset
method.
This will automatically cause a transition to the CLOSED state. else {
this._log.error(info, 'Stream error: received illegal frame.');
this.state = 'CLOSED';
this.reset(error);
this.emit('error', error);
}
}
};


The inside approach has following advantages:

My girlfriend 'K' and I decided to eat a fair amount of shrooms on a sub sandwich one morning. I might've had slightly more (about 3 g), and she had done it once before, which might account for what happened later.
After 40 minutes or so, we left my place and started walking to hers. K started feeling her body dragging her down, and I had a similar sensation that my body weight was seperating to my head and my feet. I increased talkativeness almost to the point where she was annoyed by it and said I was having 'diarrhea of the mouth'. We resolved this issue quickly before we stepped into her place so we wouldn't have a negative mindset going into the trip and into her house where her roommate was.
Once inside, she got ready for trekking around outside and talked to her roommate while I walked in circles, restless in the kitchen, only stopping to observe that the kitchen counter was bubbling up and breathing. I enjoyed this visual and K enjoyed that I was liking it, so we quick went outside to look at the beautiful landscape-like scenary. K talked about the beauty nature while I talked about the advantages of machinery. From this point on our trips seemed to be separated and I never enjoyed it to the fullest because she would always have a different perspective, mentally or physically, than mine, and it was difficult to share anything, even emotions.
It was more than an hour into it, but after this time became distorted, as well as memory and vision. I remember being amazed how different this drug was than any I had done before (alcohol, marijuana, x, dxm) and being somewhat amazed at how I could change my perspective to focus on a wider view than ever before or more intricate than ever before. I saw trails of motion as they flashed all colors of the rainbow for a second before vanishing, and K enjoyed making the trees around us dance. I began poetically philosophizing, saying things like 'the only way our minds can truly communicate is through touch' because I could tell her in words what I was seeing but she would never truly know. I knew she felt the same. It seemed that humor and seriousness flipped on and off like a switch as we observed different scenes around us.
It must've been 2 hours that passed when things really started getting crazy. K and I laid together and kissed, feeling extreme sexual urges, but resisting, as we were in a public area. We laid and looked upward and the trees and sky. I didn't recognize the sound of the river next to us as water, and things started morphing beyond my control. The spaces of sky in the trees above us filled intensely with color as my body was rushed with emotion and I felt as if I was figuring something out about the universe and K also felt a feeling of 'getting somewhere' or 'seeing the light'.
We noted that everything in the universe is a cycle and our trip, too, was creating cycles of emotions and thoughts. We also noted that our bodies felt like they weren't ours, that we were solely minds trying to escape to something better but using our bodies as vessels to get us there. Visuals intensified as K's face turned into an ogre or lizard and I really believed what I was seeing. I also saw dark worlds inside of her hair. K believed that she could jump inside of my mouth. She was enjoying, but I was growing more scared.
Suddenly out of nowhere I grew nauseous and threw up pretty quickly. Then things spiralled out of control for me and I felt very sick and negative. I didn't have the energy to stand up as I could barely control my body, and I grew VERY dizzy every time I stood up. K kept telling me that I could control it, but I tried and tried to no avail. I felt like I was going to die. I had to lay around for about an hour or more while the physical sickness went away, however during this period my memory totally messed with me. I began rapidly forgetting what was outside of the area around us, and I totally forgot my purpose. I remembered words, like student, and college, but could not think of why I was that word, or what that even meant.
I then thought of who I am, and past memories, and couldn't think of anything but vague words. These words connected to no memories or ideas at all. A good friend of mine even called my cell phone at this time and K tried to get me to talk, but I could only wonder if I knew him or not. It seemed like I should. A car drove by in the distance playing a song on the radio that I recognized and I had the feeling that the noise was a band- 4 different people. That made me wonder how many different people there actually are on the world. It felt like maybe 20 or 30 or so. Including that band (which I don't know personally).
So about 4 hours passed until I could finally walk back to her place and clean myself up. I was still dizzy as everything around me was breathing and moving and I still saw patterns of lines that weren't supposed to be there. I felt slight nausea and only felt better if I blew my nose as hard as possible because I felt like I was blowing the mushrooms out of my nose (I know, it doesn't make sense). Other than that, I laid on the floor and watched the clouds until my trip had diminished.

How To Make a Branch in Webstorm
In this section I will show you how to make a branch in webstorm to eventually be uploaded to github. First I should
define what a branch is:
Branch: A branch is a copy of your code that you can work on without effecting the master branch. This is helpful
to be able to make changes to your code and test things before you implement them into your Master branch.
Master Branch: Your master branch is your main branch where all your code goes that you know works.
Every other branch will be eventually merged into the master branch.
When you start your project you will automatically be in your master Branch which you can see on the bottom right
of webstorm. To create a new branch you would click where it says master on the bottom right,
then click, "+ New Branch". You will then be prompted with a box to name your new branch. I named mine
"explainHowToMakeNewBranch".
You will now see your new branch. You can now make changes freely without worrying about
messing up your master file. Once you like what you've done and want to commit to github, you can follow
the instructions on the how to make a commit page of this tutorial. You can then also merge this branch into the master
which I will cover in another section.
