# Webserver
- typically listens on ports 80 (HTTP) or 443 (HTTPS)
- designed to be state-less, i.e. each request is independent
- plenty of open-source software
- [Apache httpd](https://httpd.apache.org/)
- [nginx](https://nginx.org/en/)
- [express.js](https://expressjs.com) (that's for today!)
- serves static files ("web sites")
- serves endpoints ("api")
+ almost always linked to a database
+ e.g. a student database
+ GET lists all
+ GET retrieves `af42f`
+ POST creates new student
---
# Agenda
- getting started with Expressjs
- basic requests
+ header
+ URL parameters
+ body and content-types
- defining endpoints
+ verbs
+ variables
- promises
- connecting to mongo
- connecting to mysql
+ avoiding query injection
---
# Express.js
Install node.js (with npm) and express.js
```shell
$ npm install express
```
Create a `.js` file for your app:
```js
const express = require('express')
const bodyParser = require('body-parser')
const app = express()
app.use(bodyParser.text())
app.use((req, res) => { // react to any requst
console.log(req)
res.status(200).end() // sends 200 OK, no body, closes connection
})
app.listen(3000, () => console.log("Server ready on port 3000"))
```
Run it!
```shell
$ node app.js
```
---
# Syntax Refresher
We use javascript _interpreted on the server side_ -- use ES6!
```js
const a = 4 // block-scoped constant, java: final
let b = 3 // block-scoped variable, like java variable
var c = 2 // just like before: execution context scoped
```
```js
// anonymous function, old style
var square = function (arg) {
return arg * arg;
};
// lambda expression, new style
const square = (arg) => arg * arg
```
```js
var wrap = function (arg) {
console.log(arg);
return {val: arg};
};
const wrap = (arg) => {
console.log(arg)
return {val: arg}
}
```
---
# Express.js: Application-level Middleware
```js
var app = express()
app.use((req, res, next) => {
console.log('Time:', Date.now())
next()
})
```
_Middleware_ is a callback with three arguments.
`req` and `res` are the [request](https://expressjs.com/en/4x/api.html#req) and [response](https://expressjs.com/en/4x/api.html#res) objects, `next` (optional) is the next middleware.
`app.use(middleware)` triggers for every request that comes in.
---
# Specific Middleware
```js
const bodyParser = require('bodyParser')
// treat all request bodies as text/plain
app.use(bodyParser.text())
// treat all request bodies as application/json
app.use(express.json())
// serve all files in folder 'static'
app.use(express.static('static'))
// attach middleware to path (but all HTTP verbs)
app.use('/my/endpoint', (req, res, next) => {
console.log('someone accessed /my/endpoint')
next()
})
// attach middleware to path and verb
app.get('/my/endpoint', (req, res, next) => {
console.log('someone called GET /my/endpoint')
next()
})
```
---
# Accessing Headers, URL Params and Body
```js
const express = require('express')
const app = express()
app.get('/', (req, res, next) => {
console.log(req.headers)
console.log(req.params)
console.log(req.body)
res.status(200).send("Hello World!")
})
app.listen(3000, () => console.log("Server ready on port 3000"))
```
---
# Responding to Requests
```js
const express = require('express')
const app = express()
app.get('/', (req, res) => {
// status 200 and content-type text/html are set automatically
res.send("Hello World!");
})
app.post('/', (req, res) => {
// content-type application/json is set automatically
res.status(201).json({'key': 'value'});
})
app.put('/', express.json(), (req, res, next) => {
console.log(req.body)
res.status(200).end()
})
app.listen(3000, () => console.log("Server ready on port 3000"))
```

---
# Defining Endpoints
Serve static files via `app.use(express.static('folder'))`, e.g. `GET /index.html` would deliver `folder/index.html` (if exists).
_Endpoint_ of an API is where the logic is; defined by _path_ and _verb_.
```js
// GET /students/?var=value
app.get('/students/', (req, res, next) => {
// res.query.var == 'value'
res.status(200).json([]).end() // return empty array
})
// GET /students/fjdk
app.get('/students/:id', (req, res, next) => {
console.log('requested student ' + req.params.id) // "fjdk"
res.status(404).end()
})
// PUT /students/asdf {"key": "value"}
app.put('/students/:id', express.json(), (req, res, next) => {
// req.params.id == 'asdf'
// req.body is json, {key: 'value'}
})
```
---
# Refresh: Promise
A `Promise` is an object that can be resolved or rejected.
```js
somePromise
.then((arg) => {
console.log('everything seems cool: ' + arg)
})
.catch((err) => {
console.log('oops, some error: ' + err)
})
```
If the promise is resolved, the `.then` callback is executed.
If the promise is rejected, the `.catch` callback is executed.
One catch for all chained `.then` is enough (and placed last).
---
# MongoDB
Schemaless database (read: key-value store).
No table layout required, directly JSON-compatible.
Has databases and collections.
Instead of primary key: implicit `_id` field
noSQL, but has similar (yet less powerful) query language
Docker:
---
# Mongo from Express
```shell
$ npm install mongodb
```
```js
const express = require('express');
const mongo = require('mongodb');
var app = express()
const url = 'mongodb://localhost:27017/mydb';
// insert into
mongo.MongoClient.connect(url)
.then(conn => conn.collection('riko493'))
.then(coll => coll.insertOne({name: 'korbinian', user: 'riko494'}))
.catch((err) => {
console.log(err);
});
```
---
# Mongo from Express
```js
// find all objects in 'riko493'
mongo.MongoClient.connect(url)
.then(conn => conn.collection('riko493'))
.then(coll => coll.find().toArray())
.then(hits => console.log(hits))
.catch((err) => {
console.log(err);
});
// find objects in 'riko493' that match {user: 'riko493'}
mongo.MongoClient.connect(url)
.then(conn => conn.collection('riko493'))
.then(coll => coll.find({user: 'riko493'}).toArray())
.then(hits => console.log(hits))
.catch((err) => {
console.log(err);
});
```
- `deleteOne(query)`: delete the first hit
- `findOne(query)`: return the first hit (no promise)
---
# mysql
One of the most popular databases (and query languages)
Tables and views need to be defined; `ALTER TABLE` expensive.
Primary and secondary keys; not directly JSON compatible.
Powerful SQL language with views and joins.
Docker:
---
# mysql from Express
```shell
npm install mysql2
```
```js
const express = require('express')
const mysql = require('mysql2/promise') // wrap everything in promises
const app = express()
mysql.createConnection({
host: host,
user: 'user',
password: 'dbpassword',
database: 'mydb'
})
.then((conn) => conn.query('CREATE TABLE riko493 '
'(id varchar(10) not null, name varchar(20), '
'primary key (id))'))
.then((result) => console.log(result))
.catch((err) => console.log(err));
```
Use any sql query in `conn.query(...)`
---
# SQL Query Injection
![xkcd327](/assets/xkcd327-exploits-of-a-mom.png)
```js
body = {id: 'af24', name: 'Peter'}
db.query('insert into riko493 (id,name) values ('`+body.id+',"'+body.name+`'"")')
```
```js
body = {id: 'af24', name: 'Robert"); DROP TABLE riko493'} // oops...
```
Instead, use query argument replacement:
```js
db.query('insert into riko493 (id,name) values (?,?)', [body.id,body.name])
```

What do we want? Banks! When do we want them? Banks! You asked for them (or at least someone did), and now Google Pay is delivering, adding another 28 institutions
It's been several weeks since we last checked in to see the progress Google was making towards its apparent goal of signing every single financial institution in America up for Google Pay support.

Contains functions to calculate power and sample size for
various study designs used for bioequivalence studies.
See function known.designs() for study designs covered.
Moreover the package contains functions for power and sample size
based on 'expected' power in case of uncertain (estimated) variability
and/or uncertain theta0.
—–
Added are functions for the power and sample size for the ratio of
two means with normally distributed data on the original scale
(based on Fieller's confidence ('fiducial') interval).
—–
Contains further functions for power and sample size calculations based on
non-inferiority t-test. This is not a TOST procedure but eventually useful
if the question of 'non-superiority' must be evaluated.
The power and sample size calculations based on non-inferiority test may
also performed via 'expected' power in case of uncertain (estimated)
variability and/or uncertain theta0.
—–
Contains functions power.scABEL() and sampleN.scABEL() to calculate power
and sample size for the BE decision via scaled (widened) BE acceptance
limits (EMA recommended) based on simulations.
Contains also functions scABEL.ad() and sampleN.scABEL.ad() to iteratively
adjust alpha in order to maintain the overall consumer risk in ABEL studies
and adapt the sample size for the loss in power.
Contains further functions power.RSABE() and sampleN.RSABE() to calculate
power and sample size for the BE decision via reference scaled ABE criterion
according to the FDA procedure based on simulations.
Contains further functions power.NTIDFDA() and sampleN.NTIDFDA() to calculate
power and sample size for the BE decision via the FDA procedure for NTID's
based on simulations.
Contains further functions power.HVNTID() and sampleN.HVNTID() to calculate
power and sample size for the BE decision via the FDA procedure for
highly variable NTID's (see FDA Dabigatran / rivaroxaban guidances)
—–
Contains functions for power analysis of a sample size plan for ABE
(pa.ABE()), scaled ABE (pa.scABE()) and scaled ABE for NTID's (pa.NTIDFDA())
analysing power if deviating from assumptions of the plan.
—–
Contains further functions for power calculations / sample size estimation
for dose proportionality studies using the Power model.

Here are the list of the project that i have done;
- my-favorite-game https://github.com/Alex20-c/Favorite-game/tree/master
- my-first-website https://github.com/Alex20-c/first-website
About me;
Just completed with highschool last year,i have no job experience bacause i have never been employed.
I decided to take programming classes because i want to be able to solve any technical problems
that i will encounter in the world of codind and also equipe myself with technical skills.
Current intrest/Hobbies/akills
- Current intrests - Joining the next module
- To become a professional web developer
- To be equiped with technical skills
- Hobbies - Playing video games
- Swimming
- Playing table tennis
- Travelling
- skills - Junior programmer


A module containing various useful functions.
An array of ints representing the Ruby version number.
Returns whether this environment is using ActionPack version 3.0.0 or greater.
@return [Boolean]
# File lib/haml/util.rb, line 164 164: def ap_geq_3? 165: # The ActionPack module is always loaded automatically in Rails >= 3 166: return false unless defined?(ActionPack) && defined?(ActionPack::VERSION) 167: 168: version = 169: if defined?(ActionPack::VERSION::MAJOR) 170: ActionPack::VERSION::MAJOR 171: else 172: # Rails 1.2 173: ActionPack::VERSION::Major 174: end 175: 176: # 3.0.0.beta1 acts more like ActionPack 2 177: # for purposes of this method 178: # (checking whether block helpers require = or -). 179: # This extra check can be removed when beta2 is out. 180: version >= 3 && 181: !(defined?(ActionPack::VERSION::TINY) && 182: ActionPack::VERSION::TINY == "0.beta") 183: end
Returns whether this environment is using ActionPack version 3.0.0.beta.3 or greater.
@return [Boolean]
# File lib/haml/util.rb, line 189 189: def ap_geq_3_beta_3? 190: # The ActionPack module is always loaded automatically in Rails >= 3 191: return false unless defined?(ActionPack) && defined?(ActionPack::VERSION) 192: 193: version = 194: if defined?(ActionPack::VERSION::MAJOR) 195: ActionPack::VERSION::MAJOR 196: else 197: # Rails 1.2 198: ActionPack::VERSION::Major 199: end 200: version >= 3 && 201: ((defined?(ActionPack::VERSION::TINY) && 202: ActionPack::VERSION::TINY.is_a?(Fixnum) && 203: ActionPack::VERSION::TINY >= 1) || 204: (defined?(ActionPack::VERSION::BUILD) && 205: ActionPack::VERSION::BUILD =~ /beta(\d+)/ && 206: $1.to_i >= 3)) 207: end
Assert that a given object (usually a String) is HTML safe according to Rails’ XSS handling, if it’s loaded.
@param text [Object]
# File lib/haml/util.rb, line 249 249: def assert_html_safe!(text) 250: return unless rails_xss_safe? && text && !text.to_s.html_safe? 251: raise Haml::Error.new("Expected #{text.inspect} to be HTML-safe.") 252: end
Returns an ActionView::Template* class. In pre-3.0 versions of Rails, most of these classes were of the form `ActionView::TemplateFoo`, while afterwards they were of the form `ActionView;:Template::Foo`.
@param name [#] The name of the class to get.
For example, `:Error` will return `ActionView::TemplateError` or `ActionView::Template::Error`.
# File lib/haml/util.rb, line 217 217: def av_template_class(name) 218: return ActionView.const_get("Template#{name}") if ActionView.const_defined?("Template#{name}") 219: return ActionView::Template.const_get(name.to_s) 220: end
This is used for methods in {Haml::Buffer} that need to be very fast, and take a lot of boolean parameters that are known at compile-time. Instead of passing the parameters in normally, a separate method is defined for every possible combination of those parameters; these are then called using {#static_method_name}.
To define a static method, an ERB template for the method is provided. All conditionals based on the static parameters are done as embedded Ruby within this template. For example:
def_static_method(Foo, :my_static_method, [:foo, :bar], :baz, :bang, <<RUBY) <% if baz && bang %> return foo + bar <% elsif baz || bang %> return foo - bar <% else %> return 17 <% end %> RUBY
{#static_method_name} can be used to call static methods.
@overload def_static_method(klass,
name, args, *vars, erb) @param klass [Module] The class on which to define
the static method @param name [#] The (base) name of the static method
@param args [Array
(**not** to the ERB template)
@param vars [Array
to be made available to the ERB template
@param erb [String] The template for the method code
# File lib/haml/util.rb, line 349 349: def def_static_method(klass, name, args, *vars) 350: erb = vars.pop 351: powerset(vars).each do |set| 352: context = StaticConditionalContext.new(set).instance_eval {binding} 353: klass.class_eval(def #{static_method_name(name, *vars.map {|v| set.include?(v)})}(#{args.join(', ')}) #{ERB.new(erb).result(context)}end) 354: end 355: end
A version of `Enumerable#enum_with_index` that works in Ruby 1.8 and 1.9.
@param enum [Enumerable] The enumerable to get the enumerator for @return [Enumerator] The with-index enumerator
# File lib/haml/util.rb, line 294 294: def enum_with_index(enum) 295: ruby1_8? ? enum.enum_with_index : enum.each_with_index 296: end
Checks to see if a class has a given method. For example:
Haml::Util.has?(:public_instance_method, String, :gsub) #=> true
Method collections like `Class#instance_methods` return strings in Ruby 1.8 and symbols in Ruby 1.9 and on, so this handles checking for them in a compatible way.
@param attr [#] The (singular) name of the method-collection method
(e.g. `:instance_methods`, `:private_methods`)
@param klass [Module] The class to check the methods of which to check @param method [String, Symbol] The name of the method do check for @return [Boolean] Whether or not the given collection has the given method
# File lib/haml/util.rb, line 286 286: def has?(attr, klass, method) 287: klass.send("#{attr}s").include?(ruby1_8? ? method.to_s : method.to_sym) 288: end
Returns the given text, marked as being HTML-safe. With older versions of the Rails XSS-safety mechanism, this destructively modifies the HTML-safety of `text`.
@param text [String, nil] @return [String, nil] `text`, marked as HTML-safe
# File lib/haml/util.rb, line 239 239: def html_safe(text) 240: return unless text 241: return text.html_safe if defined?(ActiveSupport::SafeBuffer) 242: text.html_safe! 243: end
Maps the key-value pairs of a hash according to a block. For example:
map_hash({:foo => "bar", :baz => "bang"}) {|k, v| [k.to_s, v.to_sym]} #=> {"foo" => :bar, "baz" => :bang}
@param hash [Hash] The hash to map @yield [key, value] A block in which the key-value pairs are transformed @yieldparam [key] The hash key @yieldparam [value] The hash value @yieldreturn [(Object, Object)] The new value for the `[key, value]` pair @return [Hash] The mapped hash @see # @see #
# File lib/haml/util.rb, line 82 82: def map_hash(hash, &block) 83: to_hash(hash.map(&block)) 84: end
Maps the keys in a hash according to a block. For example:
map_keys({:foo => "bar", :baz => "bang"}) {|k| k.to_s} #=> {"foo" => "bar", "baz" => "bang"}
@param hash [Hash] The hash to map @yield [key] A block in which the keys are transformed @yieldparam key [Object] The key that should be mapped @yieldreturn [Object] The new value for the key @return [Hash] The mapped hash @see # @see #
# File lib/haml/util.rb, line 47 47: def map_keys(hash) 48: to_hash(hash.map {|k, v| [yield(k), v]}) 49: end
Maps the values in a hash according to a block. For example:
map_values({:foo => "bar", :baz => "bang"}) {|v| v.to_sym} #=> {:foo => :bar, :baz => :bang}
@param hash [Hash] The hash to map @yield [value] A block in which the values are transformed @yieldparam value [Object] The value that should be mapped @yieldreturn [Object] The new value for the value @return [Hash] The mapped hash @see # @see #
# File lib/haml/util.rb, line 64 64: def map_vals(hash) 65: to_hash(hash.map {|k, v| [k, yield(v)]}) 66: end
Concatenates all strings that are adjacent in an array, while leaving other elements as they are. For example:
merge_adjacent_strings([1, "foo", "bar", 2, "baz"]) #=> [1, "foobar", 2, "baz"]
@param enum [Enumerable] @return [Array] The enumerable with strings merged
# File lib/haml/util.rb, line 115 115: def merge_adjacent_strings(enum) 116: e = enum.inject([]) do |a, e| 117: if e.is_a?(String) && a.last.is_a?(String) 118: a.last << e 119: else 120: a << e 121: end 122: a 123: end 124: end
Computes the powerset of the given array. This is the set of all subsets of the array. For example:
powerset([1, 2, 3]) #=> Set[Set[], Set[1], Set[2], Set[3], Set[1, 2], Set[2, 3], Set[1, 3], Set[1, 2, 3]]
@param arr [Enumerable] @return [Set
# File lib/haml/util.rb, line 95 95: def powerset(arr) 96: arr.inject([Set.new].to_set) do |powerset, el| 97: new_powerset = Set.new 98: powerset.each do |subset| 99: new_powerset << subset 100: new_powerset << subset + [el] 101: end 102: new_powerset 103: end 104: end
Returns the environment of the Rails application, if this is running in a Rails context. Returns `nil` if no such environment is defined.
@return [String, nil]
# File lib/haml/util.rb, line 154 154: def rails_env 155: return Rails.env.to_s if defined?(Rails.root) 156: return RAILS_ENV.to_s if defined?(RAILS_ENV) 157: return nil 158: end
Returns the root of the Rails application, if this is running in a Rails context. Returns `nil` if no such root is defined.
@return [String, nil]
# File lib/haml/util.rb, line 143 143: def rails_root 144: return Rails.root.to_s if defined?(Rails.root) 145: return RAILS_ROOT.to_s if defined?(RAILS_ROOT) 146: return nil 147: end
The class for the Rails SafeBuffer XSS protection class. This varies depending on Rails version.
@return [Class]
# File lib/haml/util.rb, line 258 258: def rails_safe_buffer_class 259: return ActionView::SafeBuffer if defined?(ActionView::SafeBuffer) 260: ActiveSupport::SafeBuffer 261: end
Whether or not ActionView’s XSS protection is available and enabled, as is the default for Rails 3.0+, and optional for version 2.3.5+. Overridden in haml/template.rb if this is the case.
@return [Boolean]
# File lib/haml/util.rb, line 229 229: def rails_xss_safe? 230: false 231: end
Whether or not this is running under Ruby 1.8 or lower.
@return [Boolean]
# File lib/haml/util.rb, line 268 268: def ruby1_8? 269: Haml::Util::RUBY_VERSION[0] == 1 && Haml::Util::RUBY_VERSION[1] < 9 270: end
Returns the path of a file relative to the Haml root directory.
@param file [String] The filename relative to the Haml root @return [String] The filename relative to the the working directory
# File lib/haml/util.rb, line 18 18: def scope(file) 19: File.join(File.dirname(File.dirname(File.dirname(File.expand_path(__FILE__)))), file) 20: end
Silence all output to STDERR within a block.
@yield A block in which no output will be printed to STDERR
# File lib/haml/util.rb, line 129 129: def silence_warnings 130: the_real_stderr, $stderr = $stderr, StringIO.new 131: yield 132: ensure 133: $stderr = the_real_stderr 134: end
Computes the name for a method defined via {#def_static_method}.
@param name [String] The base name of the static method @param vars
[Array
# File lib/haml/util.rb, line 366 366: def static_method_name(name, *vars) 367: "#{name}_#{vars.map {|v| !!v}.join('_')}" 368: end
Converts an array of `[key, value]` pairs to a hash. For example:
to_hash([[:foo, "bar"], [:baz, "bang"]]) #=> {:foo => "bar", :baz => "bang"}
@param arr [Array<(Object, Object)>] An array of pairs @return [Hash] A hash
# File lib/haml/util.rb, line 30 30: def to_hash(arr) 31: arr.compact.inject({}) {|h, (k, v)| h[k] = v; h} 32: end
Disabled; run with --debug to generate this.

--> I shot this photo during my recent trip to Ladakh, on the way from Leh to Nubra Valley. There was a traffic jam just a half hour out of Leh, since The Dalai Lama was visiting the Nubra valley that day. People had got out of their cars and buses and were climbing up the hills to try to find out why the delay. It was early in the morning maybe around 8:30 a.m, but the sun was bright already (the sun rises well before 5:30 here during this time of the year). That explains the exposure compensation that I had to make during processing.
--> What I liked about this picture is the expression of the lady. I think the sepia tone accentuates this expression. The snap was shot in full colour and later turned into monochrome during RAW processing.
--> What I did not like about this picutre is the focus. This is all the more visible if you look at the lady's eyes, which are .. well .. blurred. Ditto with the string of beads she is wearing.

Dev Update 137: New high impact tasks
Hello contributors,
You may have noticed we've made a few changes to the DuckDuckHack list of main issues. Whereas it used to be dedicated to the Programming Mission, now it lists general high priority tasks that we're looking for help with. These tasks should have the biggest impact and will include issues from all our repositories, not just Instant Answers.
The list will be updated as we generate and categorize more issues, but in the meantime below is a selection of tasks we'd love help with...

Quick Tip
Here's something I use a lot at the command line — especially handy when you make a typing error. It's one of many keyboard shortcuts but definitely worth memorizing. Are you ready? Here it is:
[Ctrl]+[A]
That will take your cursor to the start of the current command, before you press Enter. You can remember it by recalling that A is the start of the Roman alphabet, and by association represents the start of the command you're typing. So when would you use it? Let's say I've just typed this command:
fmpeg -i myvideo.mp4 -acodec libvorbis -aq 5 -ac 2 -qmax 25 -threads 2 myvideo.webm
Notice the typo? fmpeg should be ffmpeg so I just hit [Ctrl]+[A] to jump to the start of the line and correct it, saving lots of cursor pressing. Very simple but a big timesaver over the years.

ClimateMaster Units
Closeup Look
U.S. Department of Energy: Geothermal Heat Pumps
ClimateMaster Geothermal Systems The ground absorbs nearly half of the solar energy our planet receives. As a result, the earth remains at a constant, moderate temperature just below its surface all year round. However, air temperature varies greatly from summer to winter, making air source (traditional) heating and cooling least efficient when you need it the most.
Geothermal heating and cooling systems take advantage of the stable temperature underground using a piping system, commonly referred to as a “loop.” Water circulates in the loop to exchange heat between your home, the geothermal heat pump, and the earth, providing heating, cooling, and hot water at remarkably high efficiencies. In fact, ClimateMaster geothermal heating and cooling systems are 400-600% efficient and can cut your heating, cooling, and hot water costs by up to 80%.
Geothermal HeatingDuring the winter, ClimateMaster geothermal heating and cooling systems absorb heat stored in the ground through the water that circulates in its underground loop. This heat is carried to the geothermal heat pump where it’s concentrated and then sent as warm, comfortable air throughout your home.
When you need heating the most, the air outside is coldest. As a result, a traditional air source heat pump works hard to extract the amount of heat from the cold air needed to properly heat your home. In contrast, a geothermal system consumes less energy as it easily absorbs heat from the abundant supply stored below ground, making geothermal heating significantly more energy efficient.
Gas furnaces burn natural gas to provide heat for your home and are only 98% efficient, while geothermal systems use significantly less energy collecting heat from the earth, achieving 400-600% efficiencies.
Geothermal Cooling During the summer, ClimateMaster geothermal heating and cooling systems absorb heat from your home and transfers it to the underground loop where it is then absorbed by the cooler earth. The geothermal heat pump uses the cool water returning from the earth to create cool, dehumidified air for your home.
When you need cooling the most, the outside air is hottest. A traditional air source heat pump must work hard to force the heat from your home into the already heat saturated air. In contrast, a geothermal heat pump consumes less energy as it easily rejects heat into the cool earth, making geothermal cooling significantly more energy efficient.

THE GOOD, THE BAD AND THE UGLY (IL BUONO, IL BRUTTO, IL CATTIVO) A Film Review Copyright Dragan Antulov 2000
Even in the heavenly realm of the Best Movies Ever Made there are titles that happen to be more obscure than others. THE GOOD, THE BAD AND THE UGLY is one of them. For most of the people it is nothing more than a cool title. Obscurity of this film is easy to explain - it was made decades ago, its length is epic and it belongs to the much despised genre of spaghetti westerns. Most of the people would have trouble connecting words like "spaghetti western" and "epic", unless director in charge happens to be Sergio Leone. THE GOOD, THE BAD AND THE UGLY, made in 1966, represents the final segment in his celebrated Man With No Name movie trilogy.
Unlike most of the final segments in movie trilogies, THE GOOD, THE BAD AND THE UGLY might be viewed as a prequel to first two films - A FISTFULL OF DOLLARS and FOR A FEW DOLLARS MORE. The plot is set in American Southwest during the Civil War. Tuco Ramirez (played by Eli Wallach) is a Mexican bandit with a bounty on his head. That means that he is targeted by many bounty hunters and similar shady characters interested in quick cash. The smartest of them all is Man With No Name a.k.a. Blondie (played by Clint Eastwood) who not only manages to capture Tuco but also finds a way to make him more profitable. After handing Tuco over to authorities, Blondie arranges his escapes, shares the prize money and repeats the scheme in the next county. After a while, the partnership goes sour and Tuco is left in the desert without a penny. Furious Tuco begins tracking down his former partner, but before he gets his revenge, an unusual set of events would cause him to reconsider. Both Tuco and Blondie find out about huge pile of stolen Confederate gold, but each of them knows only a part of the exact location. So, two of them decide to set aside the past differences and strike another partnership in order to get their hands on the gold. However, before they find this treasure, they must face the battling armies that stand in their way. But the deadlier obstacle to their plans comes in the form of Angel Eyes (named Sentenza in Italian version, played by Lee Van Cleef), ruthless but efficient professional killer who also knows about the hidden gold.
Same as in the first two parts of the trilogy Sergio Leone paints a revisionist picture of the Old West. Instead of using its primordial state as the perfect setting for the archetypal and simplistic fight between Good and Evil, Leone shows Old West as a place where the lack of civilisation leads to the utter lack of morality.  Therefore, the line that separates heroes from villains in this piece is blurred - they all have the same motives and same lack of scruples. Such moral ambiguity is underlined even in the title of the film, quite ironic in the context of the story and its characters. Leone used such motives in the first two films, but this time it gives it another dimension. The story is set in the broader context of American Civil War and the murderous quest by three major protagonists is dwarfed by the sheer amount of carnage and destruction that goes around them. In their quest for the gold they might kill dozens of people, but the war kills thousands. Leone's pacifist and anti- militarist stance in this movie was not just in tune with the opposition towards Vietnam War, quite popular stance among late 1960s European intellectuals. It was also inspired by the events in European past that found way to reflect them in this film. The movie was shot on location in Spain, country which endured its own civil war, with atrocities and destruction not very different from those depicted in some of the movie's most memorable scenes. The battle scene in the film, although one of the most spectacular in the history of western and although it features uniforms weapons and military equipment of 1860s America, is actually more inspired by the traumatic experiences of Italian military in 20th Century, especially WW1 and utter pointlessness and bloodbath symbolised in twelve Battles of Isonzo 1915-17.
Background of Civil War not only puts moral alignment of the characters in another context, it also gives opportunity for Leone to paint brighter or darker shades in their characters. Epic scope of the story allows Leone to also give some hints about their background. In doing that, Leone is playing with old western conventions. Angel Eyes is named Bad solely because he wears black hat; only later we see finally justify that perception when we see him as ruthless and sadistic. Lee Van Cleef obviously enjoyed playing this role, so different from righteous Colonel Mortimer from FOR A FEW DOLLARS MORE; there was only one good thing about Angel Eyes - he always adhered to his own code of professional killer. Clint Eastwood, the star of this vehicle plays the character which is the only link with two other films.  Eastwood is great as usual, playing the same immoral yet capable, intelligent character we enjoyed seeing in first two films. There is, however, some opportunities for Eastwood to show some subtle hints about his character's humanity, especially in the last segments of the film. Eastwood and Van Cleef are, however, dwarfed by the third major actor - Eli Wallach who found the role of his career in Tuco. Unlike the previous Mexican bandit role he had played in THE MAGNIFICENT SEVEN, Wallach gives great texture to his character. His Tuco is neurotic, clumsy, not very bright and he would be considered a laughing stock without his deadliness with pistols. By the usual western standards, he is not very nice person, but Wallach finds a way to make him likeable to the audience. In the end, even Leone gives opportunity to this character to tell his side of the story, in a memorable verbal exchange with his brother, played by Luigi Pistilli. This scene not only features Tuco's humanity, but also gives opportunity for Leone to implement his Marxist views in showing the poverty as the major cause of the crime.
Apart from the actors (including the supporting cast), THE GOOD, THE BAD AND THE UGLY, excels in flawless direction. With this film Sergio Leone finally matured as serious movie artist and developed his own style which many critics called "baroque". The film lasts more than two and a half hours (even longer in Italian version), but not a single scene looks unnecessary or overlong. Leone's directorial skills are at his finest, and he is equally effective in long panoramic shots (which lose much of its impact on TV, being subjected to pan&scan butchery) and his trademark short extreme close-up. Superb editing mixes those elements in perfect combination. But the most memorable element is, of course, the music. Ennio Morricone, in his long and hyperproductive career worked with many directors, but none of them used his talents as much as Leone. Entire scenes in the film are staged around Morricone's music, and not the other way around. Those themes are not self- serving - they provide the atmosphere of the film and, according to each scene, this atmosphere might be sentimental, melodramatic and sometimes even ironic (including the title theme, most recognisable, which gives humorous angle to certain events on the screen). Morricone's soundtrack is one the most powerful in the history cinema and it alone is the reason why this film should be so highly appreciated.

There is no Antimemetics Division
by qntm, 2020.
I first became aware of this book when I noticed that the good folks over at The SCP Foundation have kept themselves busy in the years since I last looked over their peerless and endlessly enthralling wiki of dry and tantalizing protocols with which to "Secure, Contain, and Protect" a catalog of creepy anomalous artifacts.
One of the arcs to break the churning surface of that crowd-sourced fictional milieu is that of the Antimemetics Division:
"An antimeme is an idea which, by its intrinsic nature, discourages people from spreading it. Think of ideas that you wouldn't share - passwords, taboos, shameful secrets.
Anomalous antimemes are another matter entirely. How do you contain something you can't record, or remember? How do you fight an enemy when you can never even know you're at war?
Welcome to the Antimemetics Division.
No, this is not your first day."
Intrigued, I started clicking around, and as is the way of SCP, discovered many hours had passed. Shortly afterwards, I realized the arc has been collected into this book.
Occasional SCP entries, in the format we know and love, intertwine a short but intense tale of memetic hazards, populated by a few of the Division's finest - those rare individuals who can go from the standing start of a hint that their memories can't be trusted, to a well-executed plan based upon a stack of assumptions about what might be needed, and what might already have been done that they can count upon, even though they no longer remember any of it, without ever retaining any knowledge of their situation, or what they're up against. I don't think I've ever been so impressed by the sheer depth of a character's resourcefulness and initiative.
The journey does contain world-ending hellscapes, with some gore, which might not be everyone's cup of tea. But it's short and somehow manages to stay light in tone, so isn't emotionally arduous on that front.
Probably my favorite fiction of the year.
For those like me with an epub fetish, you can buy There is No Antimememtics Division in many formats, including Amazon links, EPUBs, or free-to-read online, at the author's site.

IBM's Deep Blue, which defeated chess grandmaster Kasporov, is a reactive machine that sees the pieces on a chess board and reacts to them.
2. Limited memory:
Limited memory AI is mostly used in self-driving cars. They will detect the movement of vehicles around them constantly. The static data such as lane marks, traffic lights and any curves in the road will be added to the AI machine. This helps autonomous cars to avoid getting hit by a nearby vehicle. Nearly, it will take 100 seconds for an AI system to make considered decisions in self-driving.
3. Theory of mind:
Theory of mind artificial intelligence is a very advanced technology. In terms of psychology, the theory of mind represents the understanding of people and things in the world that can have emotions which alter their own behaviour. Still, this type of AI has not been developed completely in the society.
4. Self-awareness:
Self-aware AI is a supplement of the theory of mind AI. This type of AI is not developed yet, but when it happens, it can configure representations about themselves. It means particular devices are tuned into cues from humans like attention spans, emotions and also able to display self-driven reactions.

I have a usecase in my side project wherein I needed to get the thumbnail for a vimeo video. Getting this is relatively easy through vimeo’s Video Request API.
I think it’s trickier to extract the video ID from the vimeo URL. There are multiple valid Vimeo URLs. Based on this link, here are a few of the valid links:
- http://vimeo.com/12345
- http://player.vimeo.com/video/12345
- http://player.vimeo.com/video/12345?test=value1
- http://player.vimeo.com/video/12345/?test=value1
- http://vimeo.com/channels/vimeogirls/12345
- http://vimeo.com/groups/shortfilms/videos/12345
I tailored this gist by wwdboer in Ruby to extract the correct id from a given vimeo URL.
def self.vimeo_id(url)
match = url.match(/https?:\/\/(?:[\w]+\.)*vimeo\.com(?:[\/\w]*\/?)?\/(?<id>[0-9]+)[^\s]*/)
match[:id] if match.present?
end
This method will return the id if present, and nil
if not.


Chapter 4 Metadata Specification
4.1 Introduction
In the previous chapter, we learned about the IM & PMP indicators and how they are stored and constructed in the Data Hub. That is essential knowledge for you to start monitoring IM indicator data from the source to how they are presented in the IM Data Hub.
In this chapter, we’ll dive deep to the bottom and explore what lies beneath the IM Data Hub, the metadata. Metadata is data about data.
Let’s get started!
First, I’d say anything in the data hub contains metadata. Metadata defines what, why, where, and how parts are set up in the data hub. They provide references to different objects in the data hub.
Already you are familiar with datasets, data elements, or you might have heard of sections in the other chapters. All these are essentially metadata themselves.
IM Data Hub Metadata are specified in either CSV, JSON or XML formats are available at the metadata API endpoint:
https://im-dev.psi-mis.org/api/metadata
Metadata has a name, uid, code that uniquely identifies the object in the hub. It also has a sharing setting that defines the access group. We’ll talk about the access group in the following chapter.
All IM Data Hub metadata can be accessed individually by specifying their names or ids on the API endpoint. For example, the metadata for a data element with the short name suspected malaria cases
is accessed at:
In the following sections we discuss IM Data Hub metadata in three main groups;
- Organization Unit stores information about the location where IM indicator data is reported, analyzed, or presented.
- Metadata that specifies what, why, and how IM Data Hub components are set up. They include; datasets, data elements, sections, data elements groups & group sets, organization unit groups & group sets, indicators, indicator groups, categories, categories, combo, & combinations. e.t.c
- Core Metadata - any metadata that is shared publicly for re-usability across the data hub.
4.2 Organization Units (OU)
Organization Units specifies the location or where IM indicators are collected, analyzed, or presented on a dashboard.
There are two main types of OUs in the data hub.
- Test - a list of OUs for development and testing objects in the data hub. This is where we have been doing our practices.
- World - a list of OUs for production or real use in the data hub.
The main master list is accessible here
They are structured in the form of a tree or through a hierarchy to allow entries, data processing, and drill downs/ups on the dashboard. They also define access levels in the data hub. We’ll discuss access levels in chapter 5.
IM Data Hub OUs are grouped into OU groups and group sets for disaggregation of IM indicators data. We discuss the groups in section @ref{ougroup}
4.2.1 OU Trees
As we mentioned above, IM Data Hub OUs are organized in a tree-like structure that provides different levels for reporting, data processing, and presentation of IM data; in this section, we describe the OU structure by country (Fig X).
The structure is in the form hierarchy and begins with the country to subnational level 4.
| Country | Subnational level 1 | Subnational level 2 | Subnational level 3 | Subnational level 4 |
|---|---|---|---|---|
| Cameroon | Region | District | Aire de santé | Facility |
| Cote d’Ivoire | Region | District | Facility | / |
| DRC | Province | Zone de santé | Aire de santé | Facility |
Kenya County Sub-county Ward Facility Ghana Region District Sub-district Facility Mali Region District Aire de santé Facility Niger
Sierra Leone Province District Chiefdom Facility Zambia Province District Facility /
4.3 Metadata
Metadata have name
, uid
, code
at the minimum for uniquely identifying them in the hub. Others also contain short names
for unique identification.
In the following sections, we discuss the names
, uid
, code
, short name
and sharing setting
for different kinds of metadata in the data hub.
###’ data elements


This is an object for handling textual content and ajax requests. The type attribute returns the value text
. The following primitive values define the object:
To be considered as text type, the input value must be a String that does not meet the criteria for defining date, time, number or null (empty String).
The returned object has the following characteristics:
See the menu for more details.
The toString
and valueOf
methods return the browser default value.


array array_pad ( array $input , int $pad_size , mixed $pad_value )
array_pad() returns a copy of the input padded to size specified by pad_size with value pad_value. If pad_size is positive then the array is padded on the right, if it's negative then on the left. If the absolute value of pad_size is less than or equal to the length of the input then no padding takes place. It is possible to add most 1048576 elements at a time.
Returns a copy of the input padded to size specified by pad_size with value pad_value. If pad_size is positive then the array is padded on the right, if it's negative then on the left. If the absolute value of pad_size is less than or equal to the length of the input then no padding takes place.


Britain charges man arrested at Heathrow Airport with terrorism offense

public interface Part
The Part
object is used to represent a part within
a request message. Typically a part represents either a text
parameter or a file, with associated headers. The contents of
the part can be acquire as an InputStream
or as a
string encoded in the default HTTP encoding ISO-8859-1 or in
the encoding specified with the Content-Type header.
