This example shows how Telerik Calendar for ASP.NET MVC can be used to navigate to Action method passing the clicked date.
Selection(...) method gives the ability to set an Action method and a collection of dates. Calendar will render action links for every date in the collection. Thus if the date is part of the rendered month view, the day will be wrapped in a link tag with URL pointing to the Action method.
If only Action method is set, then all days will be wrapped in links with URL to the defined Action.

const picker = new tempusdominus.TempusDominus(document.getElementById('datetimepicker1'));
picker.viewDate
returns the pickers current view date.
There are a number of function here that allow for retrieving the selected dates or adding to them.
Returns an array of DateTime
of the selected date(s).
Returns the last picked DateTime
of the selected date(s).
Returns the length of picked dates -1 or 0 if none are selected.
Adds a new DateTime to selected dates array. Use this function with caution. It will not automatically refresh the widget or do any validation.
Sets the select date index (or the first, if not provided) to the provided DateTime object.
Formats a DateTime object to a string. Used when setting the input value. It is possible to overwrite this to provide more complex formatting with moment/dayjs or by hand.
Parse the value into a DateTime object. This can be overwritten to supply your own parsing.
Tries to convert the provided value to a DateTime object. If value is null|undefined then clear the value of the provided index (or 0). It is possible to overwrite this to provide more complex formatting with moment/dayjs or by hand.
Returns true if the target date is part of the selected dates array. If unit is provided then a granularity to that unit will be used.
Returns the index at which target date is in the array. This is used for updating or removing a date when multi-date is used. If unit is provided then a granularity to that unit will be used.
Clears all selected dates.
Emits Namespace.events.change
with the last picked date.
In previous version there was a function to read/write to each of the provided options. This made it easy to
use
but made the code bulky and harder to maintain. updateOptions
replaces those functions and
takes an
object of new options. This allows for multiple options to be set at the same time and works the same way as
when
setting up the picker.
If the optional reset
flag is provided then new options will be merged with the default values.
Shows or hides the widget
Namespace.events.hide
- if the widget is hidden after the toggle call
Namespace.events.show
- if the widget is show after the toggle call
Namespace.events.change
- if the widget is opened for the first time and the
input element
is empty and options.useCurrent != false
Shows the widget
Namespace.events.show
- if the widget was hidden before that call
Namespace.events.change
- if the widget is opened for the first time and the
useCurrent
is set to true or to a granularity value and the input element the
component is
attached to has an empty value
Hides the widget
Namespace.events.hide
- if the widget was visible before that callAllows developers to add/remove classes from an element. During the grid generation code, this function is called.
It provides the unit that is being generated (i.e. displaying the main date view), the date time object being effected, the current set of css classes and the container element.
Check out the example paint plugin.
Destroys the widget and removes all attached event listeners. If the picker is open it will be hidden and the event fired.
Disables the input element and the component is attached to, by adding a disabled="true"
attribute
to
it. If the widget was visible before that call it is hidden.
Namespace.events.hide
- if the widget was visible before this callEnables the input element and the component is attached to, by removing disabled
attribute from
it.
Clears all selected dates. This is a short cut to picker.dates.clear()
Instead of adding event listeners to the pickers element, you can use the subscribe method. You can provide a single event to listen for or an array of events. When providing an array the number of callbacks must be the same as the number of events.
The subscribe method returns an unsubscribe method or an array of methods if multiple events are provided.
Calling
unsubscribe remove the callback from the event listeners. Unsubscribing will not prevent
addEventListener()
from working.
const subscription = picker.subscribe(tempusdominus.Namespace.events.change, (e) => {
console.log(e);
});
// event listener can be unsubscribed to:
subscription.unsubscribe();
//you can also provide multiple events:
const subscriptions = picker.subscribe(
[tempusdominus.Namespace.events.show,tempusdominus.Namespace.events.hide],
[(e)=> console.log(e), (e) => console.log(e)]
)


Fortran + FastCGI + nginx : Possibly the fastest combination for certain web applications?
By Ricolindo dot Carino at gmail dot com
Below is an example of a simple FastCGI Fortran application that runs with the nginx webserver.
Instructions for GNU/Linux and MS Windows XP are provided.
The following instructions were tested to work in the following environment:
- Lenovo ThinkPad X200
- GNU/Linux, Ubuntu 12.04
- gfortran and spawn-fcgi installed using Ubuntu Software Center
- User is 'heeds', with 'sudo' privilege.
Part A. Download, install and configure nginx
- Download nginx (v.1.2.5) sources from http://nginx.org/en/download.html
- Unzip to /home/heeds
- Change working directory to nginx sources
$ cd /home/heeds/ngingx-1.2.5
- Install nginx
$ ./configure --without-http_rewrite_module --without-http_gzip_module
$ make
$ sudo make install
- Run nginx
$ sudo /usr/local/nginx/sbin/nginx
If the error "nginx: [emerg] bind() to <IP_ADDRESS>.80 failed ...", it means another process is using
port 80 - most probably Apache. Stop Apache, then start nginx as follows:
$ sudo service apache2 stop
$ sudo /usr/local/nginx/sbin/nginx
- Open browser, go to http://localhost. Browser should display 'Welcome to nginx!'
- Edit the nginx configuration file
$ sudo gedit /usr/local/nginx/conf/nginx.conf
Change section "location"
From:
location / {
root html;
index index.html index.htm;
}
To:
location / {
root /home/heeds/HEEDS/web;
index index.html;
}
Save and exit editor.
- Create /home/heeds/HEEDS/web/index.html as follows:

 Welcome to HEEDS via nginx!

</preb>
- Reload nginx
$ sudo /usr/local/nginx/sbin/nginx -s reload
- Reload browser. Browser should display 'Welcome to HEEDS via nginx!'
Part B. Download and install FastCGI
- Download the FastCGI development kit from http://www.fastcgi.com/dist/
- Unzip to /home/heeds/
- Change working directory to FastCGI sources
$ cd /home/heeds/fcgi-2.4.1
- Install FastCGI
$ ./configure
$ make
$ make install
- Run FastCGI example/echo
$ cd /home/heeds/fcgi-2.4.1/example
$ spawn-fcgi -a <IP_ADDRESS> -p 9000 ./echo
- Re-edit the nginx configuration file
$ sudo gedit /usr/local/nginx/conf/nginx.conf
Change section "location"
From:
location / {
root /home/heeds/HEEDS/web;
index index.html;
}
To:
location / {
root /home/heeds/HEEDS/web;
fastcgi_pass <IP_ADDRESS>:9000;
fastcgi_index index.html;
include fastcgi_params;
}
Save and exit editor.
- Reload nginx
$ sudo /usr/local/nginx/sbin/nginx -s reload
- Reload browser. Browser should display 'FastCGI echo', etc. Successive reload
will increment the 'Request number'
- Kill the 'FastCGI echo' process
$ kill -9 9066 (the actual Process ID appears after the Request number)
- Reload browser. Browser should display 'An error ocurred.'
Part C. A simple FastCGI Fortran application
- Save Fortran code in Section III below as /home/heeds/fcgi-2.4.1/example/fortran_fcgi.F90
- Compile as:
$ gfortran -o fortran_fcgi fortran_fcgi.F90 -lfcgi -Wl,--rpath -Wl,/usr/local/lib
- Execute as:
$ spawn-fcgi -a <IP_ADDRESS> -p 9000 ./fortran_fcgi
- Reload browser. Browser should display 'fortran FastCGI', etc. Enter some text in the
Username & Password fields, then click Login. Also click on the available links.
- Clicking 'Stop' will terminate the fortran_fcgi and the spawn_fcgi processes.

Section III. fortran_fcgi.F90 - A simple FastCGI application in Fortran
!
! Demonstration Fortran FastCGI program, to run with the nginx webserver
! By<EMAIL_ADDRESS>and<EMAIL_ADDRESS>!
! Requires:
! - the FLIBS modules cgi_protocol and fcgi_protocol
! - the FastCGI library
! See 'readme' for setup instructions of the compiler, nignx, and FastCGI library
!
! See 'makefile' for compile and execute commands. In summary,
! To compile test_fcgi.f90 : make
! To execute as FastCGI process : spawn-fcgi -a <IP_ADDRESS> -p 9000 ./test_fcgi
! The "-a <IP_ADDRESS>" and "-p 9000" options to spawn-fcgi must match the
! "fastcgi_pass <IP_ADDRESS>:9000;" in nginx.conf
!
! Notes:
! 1. Example 2 is from FLIBS test_cgi.f90
! 2. Customize routine respond() for your own application
!
program test_fcgi
use fcgi_protocol
implicit none
type(DICT_STRUCT), pointer :: dict => null() ! Initialisation is important!
logical :: stopped = .false. ! set to true in respond() to terminate program
integer :: unitNo ! unit number for a scratch file
! open scratch file
open(newunit=unitNo, status='scratch')
! comment previous line AND uncomment next line for debugging;
!open(newunit=unitNo, file='fcgiout', status='unknown') ! file 'fcgiout' will show %REMARKS%
! wait for environment variables from webserver
do while (fcgip_accept_environment_variables() >= 0)
! build dictionary from GET or POST data, environment variables
call fcgip_make_dictionary( dict, unitNo )
! give dictionary to the user supplied routine

BestBoard is my captstone project for the WDI program at Galvanize. It is an app that was conceived as a means of improving productivity, communication, and transparency for 501(c)3 Boards of Directors.
Per the WDI curriculum, this was an app built in less than two weeks and prominently featuring a technology that I had not used before. My unfamiliar technology here was React.js (and corresponding React libraries), which I had never personally used prior to this project.
BestBoard's current iteration has features such as account creation (protected with auth via bCrypt and JWT), voting management, static payment processing with Stripe, a calendar via React Big Calendar, data visualization with Chart.js, admin features and full CRUD functionality.
Still needed: I believe this app needs dynamic payment processing, task management tracking and document uploading to be truly complete. But who am I kidding? That's probably barely scratching the surface.

Property price prediction¶
In this tutorial, you will learn:
The basics in macroeconomic analysis
The ways of analyzing macroeconomic indicators
The ways of analyzing real estate market data
How to build a property price prediction model
Intro to macroeconomic analysis¶
As we have discussed in the first tutorial, macroeconomic analysis is a way of
investigating the macroeconomic indicators that influence the stock market.
In this module, we will first analyze the macroeconomic indicators and explore how
the indicators affect the stock prices in Hong Kong.
Then, we will specifically analyze the Hong Kong real estate market, as we believe
that it is one of the most important macroeconomic indicator that can reflect the
Hong Kong’s economy.
In addition, we will build a property price prediction model to predict the house price
of Hong Kong.
Macroeconomic indicators in Hong Kong¶
Before proceeding, first import some necessary libraries needed for this module.
import random
import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
import pandas as pd
import numpy as np
from sklearn.model_selection import train_test_split
from sklearn.preprocessing import LabelEncoder
After importing the libraries, let’s have a look at the data. The data contains 8
different macroeconomic indicators collected from 2016 to 2020.
Use
df.info()
to print information of all columns.Univariate analysis¶
In univariate analysis, use
pandas.Dataframe.describe()
to examine the
distribution of the numerical features. It returns the statistical summary such as mean,
standard deviation, min, and max of a data frame.For a better understanding of the statistics summary, use
seaborn.distplot()
to visualise the results with histograms.# Statistical summary
print(df[feature_name].describe())
# Histogram
plt.figure(figsize=(8,4))
sns.distplot(df[feature_name], axlabel=feature_name);
Bivariate analysis¶
In bivariate analysis, we are going to study the correlations between
a macroeconomic indicator and the Hang Seng Index.
Use
matplotlib.pyplot.scatter()
and seaborn.regplot()
to
visualize the relationship between two features.x = df[feature_name]
y = df['hsi']
plt.scatter(x, y)
plt.xticks(rotation=45)
fig = sns.regplot(x=feature_name, y="hsi", data=df)
Then, use
pandas.Dataframe.corr()
and seaborn.heatmap()
to compute
a pairwise correlation of features and visualize the correlation matrix.fig, ax = plt.subplots(figsize=(10,10))
cols = df.corr().sort_values('hsi', ascending=False).index
cm = np.corrcoef(df[cols].values.T)
hm = sns.heatmap(cm, annot=True, square=True, annot_kws={'size':11}, yticklabels=cols.values, xticklabels=cols.values)
plt.show()
According to the above figure, we can see that house price, GDP, population, imports,
composite consumer price index , total exports, and year are positively correlated to the
Hang Seng index, while both seasonally adjusted unemployment rate and not seasonally
adjusted unemployment rate are negatively correlated to the Hang Seng index.
The Hong Kong real estate market¶
As shown above, the house price in Hong Kong has a strong positive correlation with the
Hang Seng Index. In fact, the properties and construction sector accounts for over 10%
of weighting in the Hang Seng Index (Hang Seng Indexes Company Limited, 2020), and thus
the real estate market data is a source of volatility in the Hong Kong stock market.
While Hong Kong’s real estate market is a constant topic of discussion, it will be worth
analyzing the Hong Kong real estate market data. Using the same data analysis
technique used for the above analysis, we will now analyze Hong Kong residential
market transaction records.
Data pre-processing¶
Before analyzing the transaction records:
1. Derive some useful features from existing features.
# Add new features
df['month'] = pd.to_datetime(df['RegDate']).dt.month
df['year'] = pd.to_datetime(df['RegDate']).dt.year
2. Drop unmeaningful features and features with too many missing values
# Drop unnecessary columns
df = df.drop([feature_name], axis=1)
3. Handle missing values by replacing NAN with a mean value of a feature
# Handling missinig values
# Fill with mean
feature_name_mean = df[feature_name].mean()
df[feature_name] = df[feature_name].fillna(feature_name_mean)
Label encode categorical features
le = LabelEncoder()
le.fit(list(processed_df[feature_name].values))
processed_df[feature_name] = le.transform(list(processed_df[feature_name].values))
Economic indicator analysis¶
In economic indicator analysis, we will explore how the macroeconomic indicators affect the
monthly average house price per saleable area in Hong Kong.
The transaction records from Centaline Property will be used for this analysis.
Before analyzing the data, calculate the monthly average house price per saleable area.
Then, join the data with economic indicators by year and month.
# calculate the monthly average house price
df = df.groupby(['year','month'],as_index=False).mean()
df = df.rename(columns={'UnitPricePerSaleableArea': 'AveragePricePerSaleableArea'})
Using the bivariate analysis method we learned, a pairwise correlation of features
is computed and visualized. The result shows that population, year, composite consumer price index,
GDP, imports, and total exports are positively correlated to the monthly average
house price per saleable area in Hong Kong, while both unemployment
rates are negatively correlated to the monthly average house price per saleable area in Hong Kong.
Transaction record analysis¶
In transaction record analysis, we will examine the relationship between features describing
the house and the individual housing prices of Hong Kong.
The transaction records from Midland Realty will be used for this analysis.
In univariate analysis, the distribution of Hong Kong’s house price is examined.
The housing price of Hong Kong has a mean of 9 million HKD and a standard deviation
of 13 million HKD. The skewness and kurtosis were 26.9 and 1526.4 respectively,
showing that the housing price of Hong Kong is skewed positively to a very high
degree.
# Distribution
print(df['price'].describe())
# Skewness and kurtosis
print("Skewness: ", df['price'].skew())
print("Kurtosis: ", df['price'].kurt())
#output:
count 1.664090e+05
mean 9.133268e+06
std 1.310856e+07
min 5.500000e+05
25% 5.200000e+06
50% 6.830000e+06
75% 9.500000e+06
max 1.399000e+09
Name: price, dtype: float64
Skewness: 26.927207752922435
Kurtosis: 1526.4066673335874
In order to get a better result for the bivariate analysis, outliers are
removed by using standard deviation.
# Calculate mean and standard deviation
data_mean, data_std = np.mean(df[feature_name]), np.std(df[feature_name])
# Calculate upper boundary
upper = data_mean + data_std * 3
# Remove outliers
df = df[df[feature_name] < upper]
In bivariate analysis, the correlation coefficient between the features describing
the house and the house price is computed. 7 features with the highest correlation
is selected and shown below.
According to the above figure, the housing price in Hong Kong has (1) a strong positive
correlation with saleable area; (2) a moderate positive correlation with last
transaction price; (3) a moderate positive correlation with gross area; (4) a moderate
positive correlation with number of bedrooms; (5) a weak positive correlation with
floor; (6) a weak negative correlation with region; and (7) a weak negative correlation
with building age.
The full implementation of the economic indicator analysis and transaction data analysis
could be found in
code/macroeconomic-analysis/
in the repository.Property price prediction with machine learning¶
Based on the transaction data analysis, let’s build property price prediction models.
Train-test split¶
Use
sklearn.model_selection.train_test_split()
to split the data with the ratio
of 8:2. The input variables are the top 7 features selected from the analysis, and
the output feature is the house price.feat_col = [ c for c in df.columns if c not in ['price'] ]
x_df, y_df = df[feat_col], df['price']
x_train, x_test, y_train, y_test = train_test_split(x_df, y_df, test_size=0.2, random_state=RAND_SEED)
Log transformation¶
Before training the model, transform
y_train
using log function to normalise the highly
skewed price data. In this way, the dynamic range of Hong Kong’s property price can be reduced.log_y_train= np.log1p(y_train)
Training the model¶
In total, 4 different types of predictive models will be built:
XGBoost
Lasso
Random Forest
Linear Regression
Train the models with
x_train
and y_train
, and use the
models to make the predictions.import xgboost as xgb
# XGBoost
model_xgb = xgb.XGBRegressor(objective ='reg:squarederror',
learning_rate = 0.1, max_depth = 5, alpha = 10,
random_state=RAND_SEED, n_estimators = 1000)
model_xgb.fit(x_train, log_y_train)
xgb_train_pred = np.expm1(model_xgb.predict(x_train))
xgb_test_pred = np.expm1(model_xgb.predict(x_test))
Evaluate accuracy¶
Then, evaluate the performance of each model by root mean square log error (RMSLE).
The reason why RMSLE is used is because the price values are too big, and RMSLE prevents
penalising large differences between actual and predicted prices.
from sklearn.metrics import mean_squared_log_error
def rmsle(y, y_pred):
return np.sqrt(mean_squared_log_error(y, y_pred))
#output:
XGBoost RMSLE(train): 0.1626671056150446
XGBoost RMSLE(test): 0.16849945199484243
The train model RMSLE and the test model RMSLE are 0.1627 and 0.1685 respectively.
XGBoost uses a more accurate implementation of gradient boosting algorithm and
optimised regularisation, and hence, it gives a better result than other models.
However, in this case, the result shows that the model is slightly overfitting the train data.
The below figure shows the graph of actual and predicted property price for XGBoost.
plt.figure(figsize=(5,5))
plt.scatter(y_test,xgb_test_pred)
plt.xlabel('Actual Y')
plt.ylabel('Predicted Y')
plt.show()

Before starting, let's setup your profile in these few quick steps. If you want to skip this for now, you can go straight to your dashboard and come back to this later by going into "settings" under your user menu.
If you don't have a profile photo, let's add one:
Which school do you train at?
Your school must be listed with Google to be saved. Selecting a school will add you to the school's public members list. You can update your school at anytime.
What is your rank?
Already put in some mattime?
If you've already spent some time on the mats, let's (roughly) calculate your hours. New session hours will be added onto this. Otherwise, you can leave these as is.


As a power user I want to have my own profile I can use to post my own recipes as well as brows and rate the recipes
other people add.
Name; Susan Grimble
Age; 68 years and counting
profession; I'm retired from the post office. I stay busy looking after my grand kids after school
and participating in bake sales for local fundraisers.
Technology; I do well with basic tools on my desktop and can use the internet moderately well but I dont
own a cell phone. I can use popular websites with no trouble and enjoy looking up information on sites like wikipedia
and cooking forums. I prefer to use google chrome to search, my grand kids tell me its the best one. my home computer came
with windows seven which was nice but my grandson updated it to windows ten, I liked seven better but I'll use ten.
Attitudes and Behaviors; Susan stays busy with all the little things she likes to do. They say retirement is
the number one killer of people in her situation but not for Susan, she finds ways to keep moving and active. she does sit
and watch the Martha Stuart show every time its on but aside from that she stays engaged most of her waking hours. The
things she likes most are her grandkids and showing off her culinary skills.
Frustrations and Needs; Susan doesn’t care for idle time, she wants to keep moving but even she has to
sit down sometimes. During these times she likes to stay engaged but that can be challenging when retired. She wants to
show off her skills in the kitchen but bake sales don’t happen as often as she would like. Susan is great at the recipes
she knows but would like to continue learning and showing off her superior cooking skills with new dishes.
Goals; Susan needs to stay mentally and physically engaged if she can do that by learning more about
the art of cooking all the better. She also has a need to show off her skills and would like to help the community if possible.
Susan wants to learn as many as three new recipes a day and improve on them if she can.

In the following code snippet, I add a declaration to the environment and then try to evaluate it. However, I get an error message stating that the declaration doesn't exist. Does add_decl
create VM code for the added declaration?
example : unit := by do let my_name : name := "foo", add_decl $ mk_definition my_name [] `(unit) `(unit.star), -- get_env >>= λ env, trace $ env.contains my_name, decl ← mk_const my_name, -- eval_expr unit decl, eval_expr' unit decl, skip
I have rewritten my code to work around this. My command adds a declaration to the environment if it doesn't exist yet, and in either case, then I do something with its value. I now rewrote the code so that I don't have to evaluate the newly added declaration. Evaluating a declaration added by a previous invocation of the command works fine.
If someone finds this stream by searching: beware that if you write a command that adds a declaration to the environment if it doesn't exist yet (and then do something else), you will probably run into problems:
If file A and file B both add the same declaration to the environment, then file C which imports both of these files will raise the error that some declaration has been defined twice.

Ruby's enumerable module includes a nifty little method called #cycle. It's just like the #each method, only it won't stop iterating unless you tell it too. Once it iterates throught the last object, it will start right back at the beginning and keep going, unless you've specified a specific amount of cycles for it to run, or a specific breaking point. Lets look at an example. If we ran the code:
[1,2,3,4,5].each {|num| p num}
puts
[1,2,3,4,5].cycle(1) {|num| p num}
12345
12345
[1,2,3,4,5].each {|num| p num}
puts
[1,2,3,4,5].cycle(3) {|num| p num}
12345
123451234512345
Another interesting use of the #cycle method is that it can be used in conjunction with break to only stop running when a specific event has occured. As a simple example, lets try running something like:
i = 0
(1..10).to_a.cycle {|num| print "#{num} "; i += 1; break if i == 15}
1 2 3 4 5 6 7 8 9 10 1 2 3 4 5
Notice how it stops printing numbers halfway through the second cycle?Here, we quickly converted the range 1-10 to an array, and ran #cycle on it. But we didn't include a parameter to tell the code when to stop running. The only reason this sucker stops at all is because of the break we input at the end of the block. By including a counter "i" and increasing the value of it at every iteration through "i += 1", we can tell the code exactly when we want it to stop running, even if its only partially through the current cycle.
There are a lot of simple ways that #cycle can be used to quickly perform some tasks. I won't get too into those because there are other great resources explaining them. If you're interested, try:
Global Nerdy
Instead, I figured I'd dive into what I think would be practical applications of the #cycle method.
 You might decide to divvy up the chapters of the book by cycling through your group of friends - each taking one chapter, and then starting from the first person again. It may behoove you to write some code to figure this out. You might start with an array including your groups names:
team = [:mike, :adam, :emily, :sarah, :ken, :barbie]
Let's assume there are 100 chapters to allocate. You might then write:
i = 1
counts = {}
team.cycle {|name| counts[name] == nil ? counts[name] = [i] : counts[name] << i; i += 1; break if i == 101}
- counts[name] == nil ? -- We're asking, does the counts hash include the current name as a key, and does it have a value?
- ? counts[name] = [i] -- If there is no value (meaning the code prior to the "?" is true), then lets set the value for this key equal to an array that holds the current number we are on.
- : counts[name] << i; -- If the key already exists and has a value (which would be an array established in the prior step), lets add into that value the current number
- i += 1; -- Every time we add in a number, we want this counter to go up until we've allocated all 100 chapters
- break if i == 101 -- This determines when the cycles stop.
p counts
We'd get:{:adam=>[2, 8, 14, 20, 26, 32, 38, 44, 50, 56, 62, 68, 74, 80, 86, 92, 98], :emily=>[3, 9, 15, 21, 27, 33, 39, 45, 51, 57, 63, 69, 75, 81, 87, 93, 99], :sarah=>[4, 10, 16, 22, 28, 34, 40, 46, 52, 58, 64, 70, 76, 82, 88, 94, 100], :ken=>[5, 11, 17, 23, 29, 35, 41, 47, 53, 59, 65, 71, 77, 83, 89, 95], :barbie=>[6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, 96], :mike=>[1, 7, 13, 19, 25, 31, 37, 43, 49, 55, 61, 67, 73, 79, 85, 91, 97]}
We might clean up the output a little by using:counts.each {|k, v| p k, v}
:adam
[2, 8, 14, 20, 26, 32, 38, 44, 50, 56, 62, 68, 74, 80, 86, 92, 98]

What if you wanted to assign random chapters to you and your friends? This gets a bit more complicated, and before I take you through this let me preface this by saying that there are likely better ways of getting to the result in this example. I'd love to hear your feedback if you're aware of any!
Here is the ending code:
def randassign(team, count)
numbers = []
i = 0
count.times {|num| numbers[i] = i+1; i += 1}
rands = {}
j = 0
team.cycle do |x|
position = rand(count-j)
if rands[x] == nil
rands[x] = [numbers[position]]
else
rands[x] << numbers[position]
end
j+=1
numbers.delete_at(position)
break if numbers.count == 0
end
rands.each {|name, numbers| p name, numbers.sort}
end
randassign(team,50)
:adam
[2, 5, 10, 14, 16, 25, 44, 48, 50]
:emily
[1, 4, 7, 26, 28, 33, 38, 40]
:sarah
[17, 21, 22, 23, 32, 42, 43, 47]
:ken
[3, 13, 15, 19, 27, 29, 37, 39]
:barbie
[6, 11, 12, 18, 20, 36, 41, 45]
:mike
[8, 9, 24, 30, 31, 34, 35, 46, 49]
:adam
[1, 17, 21, 23, 27, 30, 44, 47, 48]
:emily
[3, 7, 11, 19, 22, 38, 41, 43]
:sarah
[2, 5, 12, 16, 20, 25, 36, 45]
:ken
[8, 10, 14, 18, 28, 34, 35, 49]
:barbie
[4, 9, 31, 32, 37, 39, 42, 46]
:mike
[6, 13, 15, 24, 26, 29, 33, 40, 50]
def randassign(team, count)
numbers = []
i = 0
count.times {|num| numbers[i] = i+1; i += 1}
rands = {}
This line just establishes an empty hash that will ultimately hold each team member name as a key, with corresponding arrays of chapter numbers as values.Now comes our implementation of #cycle:
j = 0
team.cycle do |x|
position = rand(count-j)
if rands[x] == nil
rands[x] = [numbers[position]]
else
rands[x] << numbers[position]
end
j+=1
numbers.delete_at(position)
break if numbers.count == 0
end
j = 0
team.cycle do |x|
position = rand(count-j)
Next, we have:
if rands[x] == nil
rands[x] = [numbers[position]]
else
rands[x] << numbers[position]
end
The next 3 lines are really important:
j+=1
numbers.delete_at(position)
break if numbers.count == 0
end
Finally, the last line of code just outputs the completed rand hash in a clean, sorted manner:
rands.each {|name, numbers| p name, numbers.sort}
Try it for yourself!I had a lot of fun working through this exercise and learning about #cycle. Feel free to tell me my example is terrible and that there are better ways of doing that. Hopefully you learned something from this post!

pop3d - Tcl POP3 server implementation
This command creates a new server object with an associated global Tcl command whose name is serverName.
The command serverName may be used to invoke various operations on the server. It has the following general form:
Option and the args determine the exact behavior of the command.
A pop3 server can be started on any port the caller has permission for from the operating system. The default port will be 110, which is the port defined by the standard specified in RFC 1939 (http://www.rfc-editor.org/rfc/rfc1939.txt). After creating, configuring and starting a the server object will listen for and accept connections on that port and handle them according to the POP3 protocol.
Note: The server provided by this module will handle only the basic protocol by itself. For the higher levels of user authentication and handling of the actual mailbox contents callbacks will be invoked.
The following commands are possible for server objects:
After this call the server will listen for connections on its configured port.
After this call the server will stop listening for connections. This does not affect existing connections.
Destroys the server object. Currently open connections are handled depending on the chosen mode. The provided modes are:
Destroys the server immediately, and forcefully closes all currently open connections. This is the default mode.
Stops the server from accepting new connections and will actually destroy it only after the last of the currently open connections for the server is closed.
Returns a list containing all options and their current values in a format suitable for use by the command array set. The options themselves are described in section Options.
Returns the current value of the specified option. This is an alias for the method cget. The options themselves are described in section Options.
Sets the specified option to the provided value. The options themselves are described in section Options.
Returns the current value of the specified option. The options themselves are described in section Options.
Returns a list containing the ids of all connections currently open.
Returns a list suitable for [array set] containing the state of the connection referenced by id.
The following options are available to pop3 server objects.
Defines the port to listen on for new connections. Default is 110. This option is a bit special. If port is set to "0" the server, or rather the operating system, will select a free port on its own. When querying -port the id of this chosen port will be returned. Changing the port while the server is up will neither change the returned value, nor will it change on which port the server is listening on. Only after resetting the server via a call to down followed by a call to up will the new port take effect. It is at that time that the value returned when querying -port will change too.
Defines a command prefix to call whenever the authentication of a user is required. If no such command is specified the server will reject all users. The interface which has to be provided by the command prefix is described in section Authentication.
Defines a command prefix to call whenever the handling of mailbox contents is required. If no such command is specified the server will claim that all mailboxes are empty. The interface which has to be provided by the command prefix is described in section Mailboxes.
Defines a command prefix to call for opening the listening socket. This can be used to make the pop3 server listen on a SSL socket as provided by the tls package, see the command tls::socket.
Here we describe the interface which has to be provided by the authentication callback so that pop3 servers following the interface of this module are able to use it.
This method is given a username and has to return a boolean value telling whether or not the specified user exists.
This method is given a username and has to return a two-element list containing the password for this user and a storage reference, in this order.
The storage reference is passed unchanged to the storage callback, see sections Options and Mailboxes for either the option defining it and or the interface to provide, respectively.
Here we describe the interface which has to be provided by the storage callback so that pop3 servers following the interface of this module are able to use it. The mbox argument is the storage reference as returned by the lookup method of the authentication command, see section Authentication.
Deletes the messages whose numeric ids are contained in the msgList from the mailbox specified via mbox.
This method locks the specified mailbox for use by a single connection to the server. This is necessary to prevent havoc if several connections to the same mailbox are open. The complementary method is unlock. The command will return true if the lock could be set successfully or false if not.
This is the complementary method to lock, it revokes the lock on the specified mailbox.
Determines the size of the message specified through its id in msgId, in bytes, and returns this number. The command will return the size of the whole maildrop if no message id was specified.
Determines the number of messages in the specified mailbox and returns this number.
Returns a handle for the specified message. This handle is a mime token following the interface described in the documentation of package mime. The pop3 server will use the functionality of the mime token to send the mail to the requestor at the other end of a pop3 connection.
The option -socket (see Options) enables users of the package to override how the server opens its listening socket. The envisioned main use is the specification of the tls::socket command, see package tls, to secure the communication.
package require tls tls::init \ ... pop3d::new S -socket tls::socket ...
This document, and the package it describes, will undoubtedly contain bugs and other problems. Please report such in the category pop3d of the Tcllib Trackers. Please also report any ideas for enhancements you may have for either package and/or documentation.
When proposing code changes, please provide unified diffs, i.e the output of diff -u.

public final class RobotAPI
This is the robot's interface with the world. This class includes the sensor and actuator methods that a robot can execute.
The field is 152.5cm by 274cm. Each goal is 50cm wide. The *goalkeeper area*, centered on the goal, is 100cm wide by 22.5cm deep. In the coordinate system used in the simulation, the *center of the field* is (0,0) with +x to the right (east) and +y up (north). The team that starts on the left side (or *west field*) is called the *west team* and the team on the right (or *east field*) is called the *east team*. The following schema sketches the main points for the west field (coordinates are in meters).

RED CORNER
By Harvey Karten, Ph.D. MGM Director: Jon Avnet: Writer: Robert King Cast: Richard Gere, Bai Ling, Bradley Whitford, Byron Mann, Tsai Chin, James Hong, Robert Stanton.
A colleague swears that he saw a picture in one of those gossip magazines featuring Richard Gere with Cheryl Crawford on one arm and the Dalai Lama on the other. Why not? No words can better sum up the Richard Gere who eats up the screen in "The Red Corner," a picture which is so cleverly digitalized that you'd swear that the action was taking place in and around Beijing's Tienanmen Square. With an opening timed to coincide with the high-profile visit of China's president, Jiang Zemin, "Red Corner" is an effective representation of Gere's views on the current Chinese regime while demonstrating that he has the highest regard for its pretty women. (The dreamily intense, socially-conscious 48- year-old actor made an impassioned plea for the sovereignty of Tibet at the 1992 Academy Awards ceremony, a year after campaigning for worldwide AIDS awareness. If you're not too clear on the connection between China's human rights abuses and the situation in its western province, see the equally politically-correct movie, "Seven Days in Tibet.")
While some films made by Chinese themselves such as "The Story of Qui Ju" more artfully criticize that country's political conditions, they cannot match Hollywood for the slick melodrama which director Jon Avnet delivers for his audience. Gere, his hair grayed over and closely cropped, is cast in the role of an businessman competing for a lucrative contract in a potentially huge market. China is undergoing radical change, some of its younger politicians eager to bring in sexy Western entertainment to replace some of the more stolid forms of diversion. Jack Moore (Richard Gere) is competing with a German executive on a plan to bring in American satellite technology to one fourth of the world's population. Seduced by a model, Hong Ling (Jessey Meng)--who seems intent on sketching Moore's long nose--he wakes up in a hotel to discover his playmate murdered and is dragged away by police.
The bulk of the story deals with Moore's unfortunate experience with the Chinese legal system and his more fortuitous relationship with his lovely, intelligent and charming attorney, Shen Yuelin (Bai Ling), who has been appointed by the court to defend him. Insisting that the best defense is a guilty plea--which would almost automatically spare him from an ignominious execution within a week of the trial's conclusion--Shen is frustrated by her client's insistence on proving his innocence.
Director Avnet allows considerable time for romantic and sentimental attachments to develop between client and lawyer. She is unmarried in a culture that considers singularity to be offensive but complains that China's one billion men are too threatened by her intelligence to ask her out. He is a widowed graduate of Harvard College and Stanford Law School, all the more desirable to Shen because he did not grow up as the pampered son of a capitalist family- -he worked his way through higher education serving at rich people's parties.
Nor does Avnet disappoint the action-adventure crowd, cramming an absurd, though heart-pounding chase as a handcuffed murder defendant rushes toward the American Embassy in a dash for sanctuary.
As in so many paranoid thrillers, the American officials are almost as villainous as the real enemy, in this case providing the businessman with little help because sensitive trade talks are under way between the U.S. and China--a clear reference to President Bill Clinton's alleged refusal to insist more strongly that China takes steps toward greater human rights in return for lucrative agreements with the States.
"The Red Corner" has its heart in the right place, even allowing its lead Chinese actress to argue that the U.S. is no paradise but rather a country with only one-sixth of China's population but with ten times its murder rate. Politically, though, the movie--from Robert King's screenplay--is whipping a dead horse since we all know by now that Communist regimes tend to be brutal, xenophobic, and reactionary. But a now mature Gere looks good on the screen and Bai Ling may even give China's premier performer, Gong Li, some heady competition. With its Casablanca-like finale, chase scenes, and political purport, "The Red Corner" is a well-made, if generally by-the-numbers, sentimental thriller, balancing the anti-Fascist agenda of a Costa-Gavras with the anti- Communist program of Jon Avnet. Rated R. Running Time: 119 minutes. (C) 1997 Harvey Karten

Huey Lewis Cancels Shows Due to Hearing Loss
By Alex Young |
"Two and a half months ago, just before a show in Dallas, I lost most of my hearing," Lewis said in a statement Friday. "I can't hear music well enough to sing. The lower frequencies distort violently making it impossible to find pitch."
After seeing a variety of ear specialists, including the Mayo Clinic and the Stanford Ear Institute, doctors diagnosed Lewis with Meniere's disease, which can cause hearing loss, tinnitus and vertigo. Doctors also recommended that Lewis discontinue touring until the condition improved.
"Therefore the only prudent thing to do is cancel all future shows," Lewis wrote. "Needless to say, I feel horrible about this and wish to sincerely apologize to all the fans… I'm going to concentrate on getting better, and hope that one day soon I'll be able to perform again."
Lewis and the News had six shows scheduled for the spring and summer, including a gig at San Francisco's Outside Lands festival, and were also on board to open for Jimmy Buffett for a stretch of dates.
In 2011, Ryan Adams was forced to take a two-year hiatus from touring due to his own battle with Meniere's disease. "All of a sudden you start seeing double and then my hand starts shaking, and then it's like you're in an elevator and the bottom just drops out and your bones feel 1,000 pounds," Adams told Rolling Stone in 2014 of his symptoms.

Billie Eilish calls out fake fans over booing incident
by Algoa FMSinger Billie Eilish is calling out fake fans for booing her as she left a US talk show earlier this month.
In a video posted online of the "Listen before I go" hitmaker leaving "Jimmy Kimmel Live!", a crowd can be seen booing the 17-year-old, apparently because she did not stop to sign autographs for waiting fans, reports aceshowbiz.com.
"The only reason I'm making this video is that I saw a video of this all happening and I just wanted to clarify what actually happened...," she says in a post on Instagram.
She added: "Because if you watch the video it looks like I'm walking by a bunch of fans and completely ignoring them and not saying hi to them, which is not what happened."
Eilish further claims the people booing were not genuine fans, but professional autograph hunters seeking to make money from her signature.
"I started to walk away because I realized none of these people actually cared about anything that had to do with me as a person," she added.
"I walked over there only to say hi, only to hug people and I got pictures of me shoved into my f**king face. I got no love whatsoever, so I left and then I got booed and called a little b**tch and got told I was going to lose my Grammy nominations. The fact that people can switch up like that..."
 I'm like, 'Bro, I'm 17'."

java.lang.Object java.security.Policy
public abstract class Policy
This is an abstract class for representing the system security policy for a Java application environment (specifying which permissions are available for code from various sources). That is, the security policy is represented by a Policy subclass providing an implementation of the abstract methods in this Policy class.
There is only one Policy object in effect at any given time.
The source location for the policy information utilized by the Policy object is up to the Policy implementation. The policy configuration may be stored, for example, as a flat ASCII file, as a serialized binary file of the Policy class, or as a database.
The currently-installed Policy object can be obtained by
calling the getPolicy
method, and it can be
changed by a call to the setPolicy
method (by
code with permission to reset the Policy).
The refresh
method causes the policy
object to refresh/reload its current configuration.
This is implementation-dependent. For example, if the policy
object stores its policy in configuration files, calling
refresh
will cause it to re-read the configuration
policy files. The refreshed policy may not have an effect on classes
in a particular ProtectionDomain. This is dependent on the Policy
provider's implementation of the
implies
method and the PermissionCollection caching strategy.
The default Policy implementation can be changed by setting the value of the "policy.provider" security property (in the Java security properties file) to the fully qualified name of the desired Policy implementation class. The Java security properties file is located in the file named <JAVA_HOME>/lib/security/java.security, where <JAVA_HOME> refers to the directory where the JDK was installed.
