grubhub
Businessmodel of GrubHub
Customer Segments
According to the GrubHub’s own information, it serves around 7 million active diners – categorised as users that have placed an order in the last 12 months – and processes more than 267,000 daily orders.
The GrubHub ordering and delivery platform is targeted at consumers that either do not have the time, capability or inclination to cook for themselves, and caters to those that want to have food delivered to their doorstep on demand. The service allows users to order food from local restaurants, rather than from large, established chains that operate their own delivery service.
GrubHub also provides its services to companies, offering corporate accounts through its sister brand Seamless. GrubHub’s service is currently available only to users across the US, where GrubHub serves more than 1,000 towns and cities, as well as in London, UK.
Value Propositions
GrubHub’s principal value to consumers is the accessibility, efficiency and breadth of its delivery platform. GrubHub enables users to order food from home or on the go, offering a wide choice of local restaurants and international cuisines, with its network including a number of restaurants that would not otherwise process delivery orders. The GrubHub platform also allows users to track their orders in real time, with customer support available on a 24-hour basis for customers that experience issues.
GrubHub also provides value to its restaurant partners, increasing their visibility and marketing reach through its online platform and enabling small businesses to complete online orders. The Company’s delivery partners are also able to earn a reasonable wage on a flexible, part-time basis, working as and when they wish.
Channels
The GrubHub platform can be accessed via the Company’s mobile and desktop websites at www.grubhub.com, or through its iOS and Android mobile apps. According to the Company’s own information approximately 60% of GrubHub orders are placed through mobile channels.
Customer Relationships
The GrubHub platform is available to consumers on a self-service basis. Customers are able to register an account, browse menus and place orders without any direct interaction with GrubHub, all via the Company’s website and mobile apps.
Delivery partners are able to apply to join the GrubHub fleet through an online form, while restaurants are required to call the Company directly in order to join the Company’s network.
GrubHub offers 24-hour customer support services and provides FAQs and information for customers on its website. It also connects with its customers and partners via its Facebook, Twitter, Instagram and YouTube accounts.
Key Activities
GrubHub develops and operates an online and mobile platform for restaurant pick-up and delivery orders. The Company’s platform allows users to place orders from a range of local restaurants and track their orders in real time.
It also provides a re-order service that allows customers to place repeat orders from their favourite restaurants.
Additionally, GrubHub manages a network of restaurant partners, with which it negotiates variable commission rates, and independent delivery partners.
Key Partners
GrubHub’s key partners are its network of restaurants across the US and London and its team of independent delivery partners. The Company includes around 44,000 restaurants in its delivery network, primarily comprising smaller, local businesses that do not have their own delivery service or online ordering system.
Where the Company’s competitors have put a greater emphasis on major cities, GrubHub has sought to partner with restaurants across many of the US’ smaller cities and towns, such as Dynasty Restaurant in Agawam, Massachusetts and A2Z Deli in Ashburn, Virginia.
GrubHub also collaborates with a fleet of independent delivery partners, who can be anyone that fulfils the Company’s criteria of having a reliable vehicle, clean driving record, car insurance and valid driver’s licence.
Key Resources
GrubHub’s key resources are its online delivery platform, its IT infrastructure, its network of delivery and restaurant partners, and its personnel.
The Company’s customer support personnel are particularly important, allowing customers to access customer assistant 24-hours a day and seven days a week.
GrubHub is recorded as the applicant in one patent application held by the US Patent and Trademark Office entitled ‘System, method and apparatus for managing made-to-order food tickets for a restaurant service’. It is also named as the assignee in two further applications for ‘Utility for determining competitive restaurants’ and ‘Utility for creating heatmaps for the study of competitive advantage in the restaurant marketplace’.
Cost Structure
GrubHub incurs costs through the development of its online platform, the maintenance of its IT infrastructure, and the retention of its full-time personnel.
While the Company does not have to own and operate its own fleet of delivery vehicles, GrubHub does pay its independent delivery partners an hourly salary.
The Company also operates offices in Chicago, New York and London, accruing rental and utility costs.
Revenue Streams
GrubHub generates revenue by collecting commissions on every order made through its platform. The Company has a variable commission rate, allowing its partners to choose their own rate of commission at or above GrubHub’s base rate.
The average commission is reported to be around 13.5%. Restaurants are incentivised to pay higher rates, however, as those offering larger commissions are generally placed higher in GrubHub’s search order than those with lower rates.
In 2015 GrubHub drove $2.4 billion in gross food sales across the US and London, generating $361.8 million in annual revenue, an increase of 43% on the previous year.


Lostintranslation cut for Cheltenham Gold Cup after winning Betfair Chase
by Will O'CallaghanLostintranslation is the new favourite for the Cheltenham Gold Cup after winning the Betfair Chase at Haydock under the ride of Robbie Power.
Colin Tizzard's charge pulled clear in a battle to overcome defending champion Bristol De Mai by one-and-a-half lengths at the finish line.
Nigel Twiston Davies' grey had been bidding to win the Grade One for the third successive year.
Frodon was a further 24 lengths behind Bristol De Mai with Ballyoptic in fourth.
It's a fourth win for Tizzard in the opening Grade One of the British National Hunt season and first since Cue Card's success in 2016.
"I got there way too soon after he travelled so well into the race. Bristol De Mai is a very good horse round here so that was a brilliant performance to beat him," Power told Racing TV.
"We're dreaming of the Gold Cup now. He was a very good novice last season but didn't know how he'd fare in the big boys' league. He's proven how good he is, roll on the King George!"

Enterprise UMA
The Gluu Server implements UMA in a way that enables the protection of any web resource. Through the oxTrust interface, the server admin can write custom authorization interception scripts which may contain logic to grant (or forbid) access. All terminology used by this page is borrowed from UMA and Connect specs.
UMA in Action
The diagrams below detail how the various UMA actors interact.
Some helpful definitions:
- Resource Owner (RO): An OAuth resource owner that is the "user" in
User-Managed Access. This is typically an end-user (a natural person)
but it can also be a corporation or other legal person.
- Resource Server (RS): Where the resources are held.
- Authorization Server (AS): A server that governs access based on resource owner policies.
- Requesting Party (RP): An end-user, or a corporation or other legal
person, that uses a client to seek access to a protected resource. The
requesting party may or may not be the same party as the resource owner.
- Client: A web or native app that is used to access a digital
resource.
- Protection API Token (PAT): An entity seeking protection API access
MUST have the scope "uma_protection". An access token with at least
this scope is called a protection API token (PAT) and an entity that
can acquire an access token with this scope is by definition a resource
server.
- Requesting Party Token (RPT): the token that a client presents to a
resource server when trying to access a protected resource.
- Authorization API Token (AAT): An entity seeking authorization API
access MUST have the scope "uma_authorization". An access token with
at least this scope is called an authorization API token (AAT) and an
entity that can acquire an access token with this scope is by
definition a client.
UMA Authorization Workflow
Detailed Authorization Overview
UMA Authorization Token Workflow
UMA Authorization Complete Sequence
Discovery
The Gluu Server exposes an endpoint for discovering information about
UMA Provider configuration. A resource server or client can perform an
HTTP GET on https://domain.com/.well-known/uma-configuration
to
retrieve a JSON object indicating the UMA Provider configuration.
Gluu Server response for UMA configuration MAY contain standard properties (defined by UMA specification) as well as custom properties (extension that is out of scope of this document). Gluu Server guarantees property name uniqueness within response.
The following is an example of a GET request to the UMA configuration discovery endpoint:
{
"version": "1.0",
"issuer": "https://gluuserver.org",
"pat_profiles_supported": [
"bearer"
],
"aat_profiles_supported": [
"bearer"
],
"rpt_profiles_supported": [
"bearer"
],
"pat_grant_types_supported": [
"authorization_code"
],
"aat_grant_types_supported": [
"authorization_code"
],
"claim_profiles_supported": [
"openid"
],
"dynamic_client_endpoint": "https://gluuserver.org/oxauth/seam/resource/restv1/oxauth/register",
"token_endpoint": "https://gluuserver.org/oxauth/seam/resource/restv1/oxauth/token",
"user_endpoint": "https://gluuserver.org/oxauth/seam/resource/restv1/oxauth/authorize",
"introspection_endpoint": "https://gluuserver.org/oxauth/seam/resource/restv1/host/status",
"resource_set_registration_endpoint": "https://gluuserver.org/oxauth/seam/resource/restv1/host/rsrc",
"permission_registration_endpoint": "https://gluuserver.org/oxauth/seam/resource/restv1/host/rsrc_pr",
"rpt_endpoint": "https://gluuserver.org/oxauth/seam/resource/restv1/requester/rpt",
"authorization_request_endpoint": "https://gluuserver.org/oxauth/seam/resource/restv1/requester/perm",
"scope_endpoint": "https://gluuserver.org/oxauth/seam/resource/restv1/uma/scopes"
}
The JSON object returned includes the following configuration information:
version
: the supported UMA core protocol version.
issuer
: the uri of the issuing authorization server.
pat_profiles_supported
: the supported OAuth token types used for
issuing Protection API Tokens (PATs).
aat_profiles_supported
: the supported OAuth token types used for
issuing Authorization API Tokens (AATs).
rpt_profiles_supported
: the supported Requesting Party Token (RPT)
profiles.
pat_grant_types_supported
: the supported OAuth grant types used for
issuing PATs.
aat_grant_types_supported
: the supported OAuth grant types used for
issuing AATs.
token_endpoint
: the uri to request a PAT or AAT.
authorization_endpoint
: the uri to request authorization for issuing a
PAT or AAT.
introspection_endpoint
: the uri to introspect an RPT.
resource_set_registration_endpoint
: the uri for a resource server to
register a resource set.
permission_registration_endpoint
: the uri for a resource server to
register a requested permission.
rpt_endpoint
: the uri for the client to request authorization data.
dynamic_client_endpoint
: the uri for registering a dynamic client.
Resource Registration
To let the Gluu Server know which resources are protected by UMA they must be registered. Resources are described by the following properties:
- name: name of resource
- scopes: scopes that are available for this resource
- type: type of resource (it can be string, uri or what ever, basically it is up to Resource Server what type it should be).
- icon_uri: uri to the icon.
These are standard properties however a resource description MAY contain custom properties.
Register resource via oxTrust
UMA Scopes
UMA Scopes are bound to resource sets and are used by policies to check whether the specified user has access to the resource. An UMA Scope is described in JSON and has the following properties:
- name: name of scope (e.g. View photo, Edit photo)
- icon_uri: optional property to specify an icon for the photo
An example of a typical JSON document of scope can be seen here:
{
"name": "Add photo",
"icon_uri": "http://www.gluu.org/icons/add_photo_scope.png"
}
The scope JSON MAY contain custom properties which are out of scope of this document.
Define UMA Scopes via oxTrust
Implementation specificity
The following types of scopes exist:
- internal: hosted on oxAuth (must provide a scope description).
- external: hosted on other servers.
- external_auto: a scope hosted on another server but which is automatically added during resource set registration or update.
Note: there is no uri for an internal scope because it is configurable and depends on oxAuth hosting.
UMA url = uma_scopes_endpoint + "/" + oxId;
http://gluu.org/uma/scopes/view = http://gluu.org/uma/scopes + "/" + view
A server has to provide a scope description as JSON document. The following uri is in use: http://gluu.org/uma/scopes/view
Note: The scope endpoint has to be present in UMA configuration to make it discoverable.
External sample ldif
dn: inum=@!1111!8990!BF80,ou=scopes,ou=uma,o=@!1111,o=gluu
displayName: View
inum: @!1111!8990!BF80

objectClass: oxAuthUmaScopeDescription
objectClass: top
oxType: internal
oxId: View
oxIconUrl: http://seed.gluu.org/uma/icons/view_scope.png
UMA Policies
UMA Policies protect UMA Resources. The protection of resources are made via scopes. Gluu Server evaluates all policies (identified by scopes) in order to grant access.
The UMA Policy main properties are:
- scopes: policy protects resources by scopes.
- authorization script: script that is evaluated in order to grant or deny access (script basically returns true or false to the server).
- name: it is best to provide an easily understandable name to the policy so that it is clear what the policy protects.
Define Policies
Within the oxTrust interface the Gluu Server admin can define UMA policies (pictured below). To achieve this, navigate to Configuration > Manage Custom Scripts > UMA Authorization policies.
You can find more information on crafting UMA policies as well as an example script here.
Algorithm
The algorithm follows theses rules:
- Policy protects resources based on scopes. If a scope is protected by a policy then during RPT authorization such a policy script has to return true in order to authorize access to resource, otherwise authorization is denied.
- Scope can be protected by multiple policies. If one scope is protected by multiple policies then all policies have to return true to authorize access. If at least one policy returned false then the authorization is denied.
Requesting party trust elevation
This section defines the OX claim profile for UMA. Following is a summary:
- Identifying uri: http://gluu.org/uma/profiles/uma-claim-gluu-1.0
- Profile author and contact information: Michael Schwartz and Yuriy Zabrovarnyy<EMAIL_ADDRESS>- Updates or obsoletes: None; this profile is new.
- Syntax and semantics of claim data: As defined below.
- Claims gathering method: As defined below.
- Error states: "need_reauthentication" in case AAT is not "strong" enough.
- Security and privacy considerations: None additional.
- Binding obligations: None additional.
If an authorization server supports the OX claim profile, it MUST supply the "ox" value for one of its "claim_profiles_supported" values in its configuration data.
To conform to this option, the authorization server MUST do the following:
- send "need_reauthentication" error in case AAT does not correspond
to authentication level and (or) mode of authorization policy.
Together with error authorization server MUST provide:
- domain_auth_level - REQUIRED. authentication level required to satisfy authorization policy.
- domain_auth_mode - REQUIRED. authentication mode required to satisfy authorization policy.
- authentication_uri - OPTIONAL. authorization server authentication uri for re-authentication with required authentication level and mode
For example:
HTTP/1.1 403 Forbidden
Content-Type: application/json
Cache-Control: no-store
{
"status": "error",
"error": "need_reauthentication",
"domain_auth_level":20,
"domain_auth_mode":"duo",
"required_acr_level":2,
"required_acr_uri":"http://example.com/global_acr",
"authentication_uri":"http://seed.gluu.org/oxauth?auth_level=20&auth_mode=duo&client_id=..."
}

The problem: http://www.tanach.us/Tanach.xml#Installation.
To show on screen (and print) acceptably texts with vowel points and cantillation (and without them), we need good fonts. It would be nice to be able to force the browser to show a page using a specified font, and there is even a declaration for that in CSS (TODO), but it is not universally supported by modern browsers/operating systems, so the user will need to install a decent font if he is not satisfied with the quality of the pre-installed ones. Font installation is easy, but we need to provide the fonts to install.
We need to be able to install fonts in cross-platform formats.
It happens that there are both a vowel and a cantillation sign under a letter (vowel is printed first in such cases (TODO)). How can we make sure that vowel and cantillation sign do not overlap?
Apple developed font format that allows inclusion (in form of tables) of instructions about combining glyphs. This format used to be called GX, and is now called AAT - Apple Advanced Typography [AAT]. It is currently supported only on MacOS (there are plans to support it in HarfBuzz [HarfBuzz] in the future (TODO)), so we can not use it.
SIL International is developing AAT replacement for Windows - Graphite [Graphite]. This format allows inclusion into the font of a program in a special language. This program then chooses and places glyphs. This format is supported on Windows and Linux, but requires installation of programs in addition' to fonts, so we can not use it.

Mat Sabu: No plans to buying new fighter jets yet
by BY AZRIL ANNUARKUALA LUMPUR, Nov 21 — Defence Minister Mohamad Sabu said the government did not plan to purchase new fighter jets and will continue with its existing fleet for the duration of the 12th and 13th Malaysia Plans.
Mohamad or Mat Sabu told Dewan Rakyat during Question Time that his ministry only plans on maintaining the US-made F/A-18D Hornet and Russian-made Su-30MKM.
“The current requirement is to procure Maritime Patrol Aircraft (MPA) and Medium Altitude Long Endurance Unmanned Aerial Vehicle (MALE UAV) as well as light fighting capabilities and training our pilots through the procurement of Light Combat Aircraft (LCA) to improve the Royal Malaysian Air Force's capabilities and its combat readiness.
“Even though we are not looking at purchasing new fighter jets, the Defence Ministry is still studying the offer from the Russian government,” said Mohamad Sabu in his reply to Pasir Mas (PAS) MP Ahmad Fadhli Shaari.
The Opposition lawmaker asked if the government was open to Moscow's offer to take back 28 problematic Su-30MKM and MiG-29 fighter jets if Malaysia bought replacements.
Currently, local firm ATAC maintains and operates the fleet at cost of RM200 million a year.
The minister also told the Lower House it would be cheaper to use unmanned drones than fighter jets for border patrol and reconnaissance flights.

We officially know when Harry Styles' new album is coming out, and we are so ready
by Alex Isaacs
Cape Town – A few weeks ago, Harry Styles released his long-awaited new single, Lights Up.
It's a guitar-driven, upbeat tune that is a step toward a more contemporary sound than his previous work on his debut album, which contained the melancholy Sign of the Times.
This more upbeat track gave fans hope that Harry's new album would be arriving soon and after what feels like an eternity the former One Direction member has finally let us know when his sophomore album will be released and its title.
The 25-year-old revealed on Twitter that the album will be dropping on Friday 13 December and its title is Fine Line.
Harry will celebrate the release of the album with a special event, titled Harry Styles – Fine Line Live at the Forum – One Night Only, in Los Angeles on Friday, 13 December.
Fans who pre-order Fine Line through his official store will gain exclusive access to pre-sale tickets, which will become available Thursday, 7 November.
Tickets will be available to the general public beginning Friday, 8 November. There is a 2 ticket maximum per purchase, and tickets will be mobile-only.
On 16 November, the singer is set to host NBC's Saturday Night Live for the first time and will perform new music from the album, along with the television performance debut of Lights Up.

Tricks for common situations
Here’s a topic overview:
Matching EOF (End Of File)
Ahh Sir, you’ll be needin what us parsers call epsilon:
rule(:eof) { any.absent? }
Of course, most of us don’t use this at all, since any parser has EOF as implicit last input.
Matching Strings Case Insensitive
Parslet is fully hackable: You can use code to create parsers easily. Here’s how I would match a string in case insensitive manner:
def stri(str)
key_chars = str.split(//)
key_chars.
collect! { |char| match["#{char.upcase}#{char.downcase}"] }.
reduce(:>>)
end
# Constructs a parser using a Parser Expression Grammar
stri('keyword').parse "kEyWoRd" # => "kEyWoRd"@0
Testing
Parslet helps you to create parsers that are in turn created out of many small parsers. It is really turtles all the way down. Imagine you have a complex parser:
class ComplexParser < Parslet::Parser
root :lots_of_stuff
rule(:lots_of_stuff) { ... }
# and many lines later:
rule(:simple_rule) { str('a') }
end
Also imagine that the parser (as a whole) fails to consume the ‘a’ that
simple_rule
is talking about.
This kind of problem can very often be fixed by bisecting it into two possible problems. Either:
- the
lots_of_stuff
rule somehow doesn’t placesimple_rule
in the right context or - the
simple_rule
simply (hah!) fails to match its input.
I find it very useful in this situation to eliminate 2. from our options:
require 'rspec'
require 'parslet/rig/rspec'
class ComplexParser < Parslet::Parser
rule(:simple_rule) { str('a') }
end
RSpec.describe ComplexParser do
let(:parser) { ComplexParser.new }
context "simple_rule" do
it "should consume 'a'" do
expect(parser.simple_rule).to parse('a')
end
end
end
RSpec::Core::Runner.run(['--format', 'documentation'])
Output is:
Example::ComplexParser simple_rule should consume ‘a’
Finished in 0.00094 seconds (files took 0.29367 seconds to load) 1 example, 0 failures
Parslet parsers have one method per rule. These methods return valid parsers for a subset of your grammar.
Error reports
If your grammar fails and you’re aching to know why, here’s a bit of exception handling code that will help you out:
parser = str('foo')
begin
parser.parse('bar')
rescue Parslet::ParseFailed => error
puts error.parse_failure_cause.ascii_tree
end
This should print something akin to:
Expected "foo", but got "bar" at line 1 char 1.
These error reports are probably the fastest way to know exactly where you went wrong (or where your input is wrong, which is aequivalent).
And since this is such a common idiom, we provide you with a shortcut: to get the above, just:
require 'parslet/convenience'
parser.parse_with_debug(input)
Reporter engines
Note that there is currently not one, but two error reporting engines! The default engine will report errors in a structure that looks exactly like the grammar structure:
class P < Parslet::Parser
root(:body)
rule(:body) { elements }
rule(:elements) { (call | element).repeat(2) }
rule(:element) { str('bar') }
rule(:call) { str('baz') >> str('()') }
end
begin
P.new.parse('barbaz')
rescue Parslet::ParseFailed => error
puts error.parse_failure_cause.ascii_tree
end
Outputs:
Expected at least 2 of CALL / ELEMENT at line 1 char 1. `- Expected one of [CALL, ELEMENT] at line 1 char 4. |- Failed to match sequence ('baz' '()') at line 1 char 7. | `- Premature end of input at line 1 char 7. `- Expected "bar", but got "baz" at line 1 char 4.
Let’s switch out the ‘grammar structure’ engine (called ‘Tree
’)
with the ‘deepest error position’ engine:
class P < Parslet::Parser
root(:body)
rule(:body) { elements }
rule(:elements) { (call | element).repeat(2) }
rule(:element) { str('bar') }
rule(:call) { str('baz') >> str('()') }
end
begin
P.new.parse('barbaz', reporter: Parslet::ErrorReporter::Deepest.new)
rescue Parslet::ParseFailed => error
puts error.parse_failure_cause.ascii_tree
end
Outputs:
Expected at least 2 of CALL / ELEMENT at line 1 char 1. `- Expected one of [CALL, ELEMENT] at line 1 char 4. |- Failed to match sequence ('baz' '()') at line 1 char 7. | `- Premature end of input at line 1 char 7. `- Premature end of input at line 1 char 7.
The 'Deepest'
position engine will store errors that are the
farthest into the input. In some examples, this produces more readable output
for the end user.
Line numbers from parser output
A traditional parser would parse and then perform several checking phases, like for example verifying all type constraints are respected in the input. During this checking phase, you will most likely want to report screens full of type errors back to the user (‘cause that’s what types are for, right?). Now where did that ‘int’ come from?
Parslet gives you slices (Parslet::Slice) of input as part of your tree. These are essentially strings with line numbers. Here’s how to print that error message:
# assume that type == "int"@0 - a piece from your parser output
line, col = type.line_and_column
puts "Sorry. Can't have #{type} at #{line}:#{col}!"
Precedence climber
You might want to implement a parser for simple arithmetic infix expressions such as `1 + 2`. The quickest way to do this with parslet is to use the infix expression parser atom:
infix_expression(
match('[0-9]').repeat,
[str('*'), 2],
[str('+'), 1]) # matches both "1+2*3" and "1*2+3"
Please also see the example and the inline documentation for this feature.

Clone the gae-init project to get the code locally on your computer using Git:
$ git clone https://github.com/gae-init/gae-init.git phonebook
If you are more familiar with Mercurial use:
$ hg clone https://bitbucket.org/gae-init/gae-init phonebook
This will create a new directory that is called phonebook

Login System Tutorial Part 7 - Logout¶
In this tutorial, we will talk about logging out a user account from the home page.
First of all, go to home.html in the templates folder and add logout button below the user login status.

Login as {{.User}}
{{if eq .OTP true}} with {{else}} without {{end}}
2FA Authentication

{{.Message}}

<form method="POST">

</form>

Now go to login.go in views folder and apply the following codes below to delete the cookie when the user logged out his account:
if r.FormValue("request") == "login" {
// Some codes
}
// Check if the request submitted is logout
if r.FormValue("request") == "logout" {
// Assign the message to the Message field of userContext
userContext.Message = "User has logged out."
// Logout the user in uAdmin
uadmin.Logout(r)
// Deletes the cookie
usersession := &http.Cookie{
Name: "user_session",
Value: "",
MaxAge: -1,
}
http.SetCookie(w, usersession)
// Pass the userContext data object to the HTML file
uadmin.RenderHTML(w, r, "templates/login.html", userContext)
return
}
Run your application. Go to the login path in the address bar (e.g. http://localhost:8080/login/). Assign the username and password in the login form (e.g. admin, admin). Click Login button to submit.
As expected, the logout button has been created in the form. Click Logout button and see what happens.
Result
Now check the user_session cookie to ensure that it was deleted.
Click here to view our progress so far.
In the next part, we will discuss about reading a cookie and getting the user from the model based on the value of the cookie to ensure that the user is active.


This keyboard is designed for the Tamil language and based on the Tamil typewriter layout. The keyboard is designed for users who are familiar with both this layout and the Tamil script, and is intended for use with a normal QWERTY (English) keyboard.
This keyboard layout is based on the Tamil typewriter, with separate keys for consonants, vowels and vowel components. Most of the characters used in Tamil are combinations of consonants and vowels, and these do not appear on the keyboard. Instead, the appropriate vowel component is typed after the consonant.
For example, the standalone vowel இ is entered by typing ,, but in combination with a consonant, the ி component (p key) is usually typed instead, after the consonant, and the consonant-vowel combinant will be displayed. Pressing Backspace once will delete only the vowel component, so the character displayed on the screen will change back to the consonant, and change again if a different component is typed.
Grantha letters, which are used for typing Sanskrit, appear on the keyboard and are treated as normal consonants.
| Language | Phrase | Meaning | Type the following keys |
| Tamil | தமிழ் | "Tamil" | jkpH; |
The visible keyboard layout consists of the eighteen consonants க ங ச ஞ ட ண த ந ப ம ய ர ல வ ழ ள ற ன, the five Grantha consonants and SRiiஸ ஷ ஜ ஹ க்ஷ ஸ்ரீ, eleven vowels அ ஆ இ ஈ உ ஊ எ ஏ ஐ ஒ ஓ, a range of vowel components and combinants characters, and the Pulli ் and Aytham ஃ marks, as well as various punctuation marks. The majority of characters are typed using a combination of keystrokes.
Although many Tamil characters are typed using separate keys for consonants and components, the characters that appear on screen will be combinants, which the computer sees as a single character. This means that while two (or more) keystrokes are required to display most consonant-vowel combinants, when you use the arrow keys to move the cursor through the text, only a single keystroke is needed to move past each character. Moving the cursor to the left of a combinant character and pressing Delete will erase the whole character, but if you move the cursor to the right of a combinant and press Backspace, only the vowel component will be erased. This is the case whether the vowel component appears to the left or right of, above or below the consonant.
The standalone vowel characters which are on the keyboard will produce that character and will not combine with consonants. Long vowels have their own keys. Vowel-consonant combinant characters are entered either by typing a specific key for that combinant or by typing the consonant and vowel components separately.
Vowel components that combine with consonants are always typed after the consonants, even when the vowel component appears before (to the left of) the consonant component (such as ெ or ே). If vowel components are typed before a consonant, they will not be combined with that consonant.
Because the consonants contain the implicit vowel அ, to produce a pure consonant it is necessary to add the Pulli mark ் by typing a semicolon ; immediately after the consonant. Any vowel component that is typed immediately after typing the Pulli mark will not be combined with the consonant. However, because this keyboard acts in a similar way to a typewriter, it is possible to type a preceding vowel component followed by a consonant and the Pulli mark, or even a standalone vowel followed by the Pulli mark, producing odd combinations such as மெ் or அ். In every case, a consonant-Pulli mark combinant behaves the same way as a consonant-vowel combinant when you use the arrow, Backspace and Delete keys.
This character is entered by typing _ (Shift+Underscore or Shift+Hyphen). Currently, some browsers do not display this character correctly.
Note: for a complete table of characters and keystrokes, click here.
The following table gives specific examples of how to input characters based on the consonant க. The Grantha consonants, which are entered with [S*] key combinations, use the same input method. Examples of these with the consonant ஜ are also given below.

Organization
This book has 20 chapters. Each chapter is devoted to a particular
kind of recipe, such as algorithms, text processing, databases, and
so on. The 1st edition had 17 chapters. There have been improvements
to Python, both language and library, and to the corpus of recipes
the Python community has posted to the cookbook site, that convinced
us to add three entirely new chapters: on the iterators and
generators introduced in Python 2.3; on Python's
support for time and money operations, both old and new; and on new,
advanced tools introduced in Python 2.2 and following releases
(custom descriptors, decorators, metaclasses). Each chapter contains
an introduction, written by an expert in the field, followed by
recipes selected from the online cookbook (in some casesabout
5% of this book's recipesa few new recipes
were specially written for this volume) and edited to fit the
book's formatting and style requirements. Alex (with
some help from Anna) did the vast majority of the
selectiondetermining which recipes from the first edition to
keep and update, and selecting new recipes to add, or merge with
others, from the nearly 1,000 available on the site (so, if a recipe
you posted to the cookbook site didn't get into this
printed edition, it's his
fault!). He also decided which subjects just had
to be covered and thus might need specially written
recipesalthough he couldn't manage to get
quite all of the specially written recipes he
wanted, so anything that's missing, and
wasn't on the cookbook site, might not be entirely
his fault.
Once the selection was complete, the work turned to editing the
recipes, and to merging multiple recipes, as well as incorporating
important contents from many significant comments posted about the
recipes. This proved to be quite a challenge, just as it had been for
the first edition, but even more so. The recipes varied widely in
their organization, level of completeness, and sophistication. With
over 300 authors involved, over 300 different
"voices" were included in the text.
We have striven to maintain a variety of styles to reflect the true
nature of this book, the book written by the entire Python community.
However, we edited each recipe, sometimes quite considerably, to make
it as accessible and useful as possible, ensuring enough uniformity
in structure and presentation to maximize the usability of the book
as a whole. Most recipes, both from the first edition and from the
online site, had to be updated, sometimes heavily, to take advantage
of new tools and better approaches developed since those recipes were
originally posted. We also carefully reconsidered (and slightly
altered) the ordering of chapters, and the placement and ordering of
recipes within chapters; our goal in this reordering was to maximize
the book's usefulness for both newcomers to Python
and seasoned veterans, and, also, for both readers tackling the book
sequentially, cover to cover, and ones just dipping in, in
"random access" fashion, to look
for help on some specific area.
While the book should thus definitely be accessible
"by hops and jumps," we
nevertheless believe a first sequential skim will amply repay the
modest time you, the reader, invest in it. On such a skim, skip every
recipe that you have trouble following or that is of no current
interest to you. Despite the skipping, you'll still
get a sense of how the whole book hangs together and of where certain
subjects are covered, which will stand you in good stead both for
later in-depth sequential reading, if that's your
choice, and for "random access"
reading. To further help you get a sense of what's
where in the book, here's a capsule summary of each
chapter's contents, and equally capsule bios of the
Python experts who were so kind as to take on the task of writing the
chapters'
"Introduction" sections.
- Chapter 1, introduction by Fred L. Drake, Jr.
-
This chapter contains recipes for manipulating text in a variety of
ways, including combining, filtering, and formatting strings,
substituting variables throughout a text document, and dealing with
Unicode.
Fred Drake is a member of the PythonLabs group, working on Python
development. A father of three, Fred is best known in the Python
community for single-handedly maintaining the official documentation.
Fred is a co-author of Python & XML
(O'Reilly).
- Chapter 2, introduction by Mark Lutz
-
This chapter presents techniques for working with data in files and
for manipulating files and directories within the filesystem,
including specific file formats and archive formats such as
tar and zip.
Mark Lutz is well known to most Python users as the most prolific
author of Python books, including Programming
Python, Python Pocket Reference, and
Learning Python (all from
O'Reilly), which he co-authored with David Ascher.
Mark is also a leading Python trainer, spreading the Python gospel
throughout the world.
- Chapter 3, introduction by Gustavo Niemeyer and Facundo Batista
-
This chapter (new in this edition) presents tools and techniques for
working with dates, times, decimal numbers, and some other
money-related issues.
Gustavo Niemeyer is the author of the third-party
dateutil module, as well as a variety of other
Python extensions and projects. Gustavo lives in Brazil. Facundo
Batista is the author of the Decimal PEP 327, and of the standard
library module decimal, which brought
floating-point decimal support to Python 2.4. He lives in Argentina.
The editors were delighted to bring them together for this
introduction.
- Chapter 4, introduction by David Ascher
-
This chapter includes recipes for many common techniques that can be
used anywhere, or that don't really fit into any of
the other, more specific recipe categories.
David Ascher is a co-editor of this volume. David's
background spans physics, vision research, scientific visualization,
computer graphics, a variety of programming languages, co-authoring
Learning Python (O'Reilly),
teaching Python, and these days, a slew of technical and nontechnical
tasks such as managing the ActiveState team. David also gets roped
into organizing Python conferences on a regular basis.
- Chapter 5, introduction by Tim Peters
-
This chapter covers techniques for searching and sorting in Python.
Many of the recipes explore creative uses of the stable and fast
list.sort in conjunction with the
decorate-sort-undecorate (DSU) idiom (newly built in with Python
2.4), while others demonstrate the power of heapq,
bisect, and other Python searching and sorting
tools.
Tim Peters, also known as the tim-bot, is one of
the mythological figures of the Python world. He is the oracle,
channeling Guido van Rossum when Guido is busy, channeling the
IEEE-754 floating-point committee when anyone asks anything remotely
relevant, and appearing conservative while pushing for a constant
evolution in the language. Tim is a member of the PythonLabs team.
- Chapter 6, introduction by Alex Martelli
-
This chapter offers a wide range of recipes that demonstrate the
power of object-oriented programming with Python, including
fundamental techniques such as delegating and controlling attribute
access via special methods, intermediate ones such as the
implementation of various design patterns, and some simple but useful
applications of advanced concepts, such as custom metaclasses, which

My name is Jaiven Smith, I was born and raised in Lexington, Kentucky, and I am currently a first-year student at the University of Kentucky. Throughout my years in high school, I enjoyed challenging myself in Bryan Station's Information Technology program. As a result of my participation, I was able to learn many skills including Studio Directing and Performance, App Development with the Ionic Framework, Photography, and so much more. I've been able to take these skills with me to Washington DC for the Congressional App Challenge, as well as to Silicon Valley to talk to tech companies about the future of our projects. Let's make something together!
I conducted surveys, created presentations, and developed a marketing strategy for a mobile app. Overall, our project "Phones Down" was deemed "best in the state" out of hundreds of competitors.
On a new team of peers, I was able to guide a project from beginning-to-end. Using a hybrid development process we were able to completely finish a mobile app and develop a unique marketing strategy for it. The App is called "Informed".
As a marketer on this team, it was my job to make sure people understood how our app worked and how it would benefit our users. This project was called "LexApp", it was designed to help the citizens of Lexington, Kentucky get involved with local government.
In my free time, I love to take pictures, play guitar, go to the gym or anything that challenges me to be a better person.
I believe in doing something little every day to contribute to an overall, happy and healthy life.


A Classy Bike
Classes in Ruby
March 26, 2016
A while back I accompanied my partner on his quest for a new bike (SPOILER: no, he didn't buy a vintage Schwinn Sting-Ray). He had signed up to do a 7-day, 550-mile fund-raising ride from San Francisco to Los Angeles, and his previous bike was about 100 pounds of stone and bear sinew. OK, that last part is an exaggeration, but seriously, bikes have come sooo far and have substantially diversified since his previous 1990's bike. Still, no matter the great diversity and numbers of bicycles today,there are a lot of attributes and behaviors that all bikes share.
When we write software, we need a way to easily model real-world objects. So as not to constantly duplicate our efforts, it's nice to have a software template from which to create multiple of the same type of object. But no matter how similar two objects are, they also usually have differences. How to resolve this conundrum?
For example, let's say Freewheelin Bicycles Ltd needs to create an inventory of all the bikes it manufactures as well as model, in software, how each bike performs under different conditions. Each time they design a new bike, it has to be represented in the system. All bikes have many types of attributes and behaviors in common. All bikes have a name, a type, a size, a color, a number of speeds, a component set. All bikes can brake, can turn, can switch gears. But each model has different values for these attributes (e.g. type: mountain, road, racing; color: red, black, white) and different methods for performing those behaviors (e.g. brake: hand brake, coaster brake).
The way we make this easier in software is by declaring a Class of Bicycle. A Class is like a template, from which you can specify different specific bikes. A Class contains attributes and behaviors. When you create a new individual copy of a Class, it's called an instance, or an object, of that Class. In Ruby, an instance's attributes are instance variables and an instance's behaviors are methods. In our example, we have the Class Bicycle with attributes name, type, size, color, number of speeds, and component set, and with methods brake, turn, and switch gears. Freewheelin Bicycles Ltd has just come out with a new road model, the Screamer. To represent this in the software, we make a new instance of the Bicycle Class. This instance we'll give the name Screamer, type road, color red. We'll also specify how to brake, turn, and switch gears on the Screamer. The Ruby Class will look like this:
And the code to create the new Screamer instance of Class Bicycle:
class Bicycle
@name
@type
@size
@color
@num_gears
@component_set
def initialize(new_name, new_type, new_size, new_color, new_num_gears,
new_component_set, new_stock)
@name = new_name
@type = new_type
@size = new_size
@color = new_color
@num_gears = new_num_gears
@component_set = new_component_set
@stock = new_stock
def brake
# code to model braking goes here
end
def turn
# code to model turning goes here
end
def switch_gears
# code to model switching gears goes here
end
end
screamer = Bicycle.new("screamer", "road", 26, "red", 21, "Shimano", 5)
Now, when we want to see how many Screamers there are, or what color it is, we can access the variable screamer.
You've just had a quick, simple introduction to what a Class is, how it works, and how to create one in Ruby. Now scamper off on your Sting-Ray and write some code!

AR Map
AR Map with Live Location
Unity 3D
Problem
Opening maps, waiting for it to load and searching your location in a small screen of a mobile can be sometimes frustrating & pretty boring as well. Boring why? I mean it's not in AR ofcourse :).
The Solution
This AR application provides a interesting solution to the problem. By using the power of MapBox SDK and AR Foundation, it can successfully show us a 3D map in augmented space with the precise location of the user. The user would know their exact location (no matter whichever part of the world they are from) and also get entertained by using a different kind of app rather than the same monotonous boring one. The app also provides 3D elevation to houses/buildings with polygons and also shows proper elevation in places like hills etc. Points of interests such as restaurants, services, transport facilities, etc are also shown on the map with suitable icons
Tech Stack
- Unity3D
- Google AR Core & AR Foundation
- MapBox SDK
- Blender
Version 1.2
Notable Changes
- With v1.2, the user can also see a version of the map with satellite imagery which gives a more accurate description of the environment like hills, plains etc with ofcourse elevation.
Version 0.7
Notable Changes
- The app also provides 3D elevation to houses/buildings with polygons and also shows proper elevation in places like hills etc.
- Added points of interests such as restaurants, services, transport facilities, etc on the map with suitable icons

DEPRESSION IS A COMMON BUT SERIOUS MEDICAL THAT AFFECTS PEOPLE OF EVERY AGE, RACE, ETHNICITY, AND INCOME LEVEL. WITH THE RIGHT TREATMENT AND SELFCARE, EVEN PEOPLE WITH THE MOST SEVERE DEPRESSION CAN FEEL NORMAL AGAIN
Major depression is different than “the blues,” and it certainly is not a
sign of weakness. The exact cause is unknown, but it is most likely caused by
a combination of genetic and environmental factors.
Common symptoms of depression include:
If you think that you are experiencing depression, it is important that you visit your health care provider as soon as possible. In order to make a diagnosis, he/she may:
If you are diagnosed with depression, one or more of the following modes of treatment may be recommended:
An important part of overcoming depression is to take good care of yourself mentally AND physically:

9.1. How to Change the Configuration from the Default Configuration¶
Table of Contents
9.1.1. Structure of configuration file¶
Nablarch configuration consists of the configuration files in the default configuration and configuration files in the PJ deliverables.
Structure of the configuration file is shown below.
| Module | Description |
|---|---|
| Default configuration (jar) | Default configuration is packaged in the jar format such as nablarch-main-default-configuration-XXXX.jar and nablarch-testing-default-configuration-XXXX.jar, and distributed as Maven artifacts.|br| Some items have values set for placeholders, and some have only placeholders defined.|br| For items that are changed very rarely, placeholders are not used and values are set directly. |
| PJ deliverables | When using the archetypes provided by Nablarch, the dependency on the default configuration (jar) is set in advance. In the component configuration file of PJ deliverables, the components are provided immediately after they are generated from the archetype, with default values set. |
9.1.2. How to customize¶
<IP_ADDRESS>. Pattern of customization¶
Following are the patterns by which the configuration files of PJ deliverables can be customized.
- Overwriting environment configuration values
- Overriding environment configuration values
- Overriding the component definition
- Customization of handler configuration
The details will be described later.
9.1.3. Customization procedure¶
<IP_ADDRESS>. Overwriting environment configuration values¶
The environment configuration values that are frequently changed in PJ are configured in the configuration file of a blank project generated by the archetype.
See Item Name Rule for Environment Configuration Valuesfor the naming rules for configuration item names.
<IP_ADDRESS>.2. Modifying the configuration items where TODO comment is embedded¶
TODO comment is embedded in the configuration file (config file) at places to be modified almost certainly in each project, such as DB connection configuration. Modify the set values at such places.
<IP_ADDRESS>.3. Changing the default value if the PJ requirements are not met with the default value¶
Check the Default configuration list
and wherever the default value does not meet the PJ requirements, modify the configuration file (config file).
<IP_ADDRESS>. Overriding environment configuration values¶
If you want to override the environment configuration values configured in the configuration file (config) of the default configuration, redefine them with a placeholder of the same name.
In the Default configuration list
, you can check the contents configured in the default configuration.
<IP_ADDRESS>. Overriding the component definition¶
If a placeholder is not used for the property of the component in the component configuration file of the default configuration that you want to change, or if you want to change the component itself to a different class that you customized in the project, redefine each component in the component configuration file of the PJ deliverables.
The settings for which placeholder is not used can be checked in the default configuration in the Default configuration list
.
If you need to change the component definition from the default settings, follow these steps to redefine the component.
<IP_ADDRESS>.1. Defining a component with the same name¶
Identify the component to be changed from the component definition (xml) of the default configuration, and fetch the component name.
For example, when replacing the following component, you can see that the component name is idGenerator
.
<!-- Numbering module configuration -->
<component name="idGenerator"
class="nablarch.common.idgenerator.TableIdGenerator">
<!-- Numbering table definition -->
<property name="tableName" value="ID_GENERATE" />
<property name="idColumnName" value="ID" />
<property name="noColumnName" value="NO" />
</component>
Define a component with the same name as the component you want to replace in any component configuration file.
[Contents of the redefinition file]
<!-- Numbering module configuration (use Oracle sequence) -->
<component name="idGenerator"
class="com.example.common.idgenerator.OracleSequenceIdGenerator">
<property name="idTable">
<map>
<entry key="1101" value="USER_ID_SEQ"/>
</map>
</property>
</component>
Tip
If more than one component definition has the same name, the setting described later takes precedence.
Redefine components using this Nablarch specification.
<IP_ADDRESS>.2. (When a component configuration file is created) Read the created component configuration file¶
The description example of the component configuration file is shown below.
<!-- Previous is omitted-->
<!-- Numbering function -->
<import file="nablarch/common/idgenerator.xml" />
<!-- Read component definition of PJ and override the default component definition -->
<import file="pj_component.xml"/>
</component>
</component-configuration>
<IP_ADDRESS>. Customization of handler configuration¶
Based on the handler configuration of the generated component, examine the necessary handler configuration for PJ.
An example of customization is given below.
- A dedicated handler will be added to support feature phones.
- Handlers of functions not used by PJ will be excluded.
In the component configuration file
(XXX_component_configuration.xml
) generated by the Maven archetype,
the minimum handler configuration for the processing architecture is defined in advance.
To change the handler configuration in PJ, edit this file.
9.1.4. Example of configuration change¶
See below for specific examples of changing the configuration of the component configuration file and the configuration file (config file).
- Procedure for Changing the Message ID and Message Content
- Procedure to add available characters
- Procedure to rename a table used by Nablarch framework

STILL
ON THE
JOURNEY
Web Extension for the Colorblind
Usability Study and User experience
Color vision deficiency affects hundreds of millions of people in the world today. The problems colorblind people experience while interacting with computers, specifically when using web browsers, is our primary concern. Our project aims to find and prototype a solution for colorblind people when viewing and interacting with modern web applications. Through this project, we want to apply design skills to these specific individuals and address some of the challenges in their daily life. To better understand our target audience, we conducted interviews with a group of colorblind people to determine their requirements and expectations of our project.
Our research shows that there are currently no sufficient solutions offered in this area to help colorblind people identify color better in this context. However, this remains a problem since these users still want some kind of assistance when working with web pages, which is not being sufficiently addressed. After conducting interviews with colorblind people, we decided to create a web browser extension to help users view visual data on the Internet more easily, specifically in web applications that use a lot of color to convey information.
Collaborated with four students with different backgrounds, we are seeking for answers to best aid colorblind people in viewing and interacting with modern web applications. In this project, I went through the entire process of doing an HCI project, starting from filling IRB forms to making presentation of the work after several times of iteration. The methods we used include a combination of rigorous and empirical field studies and lab based evaluation techniques.
The above pictures patially demonstrated the process of our team doing the usability studies.
This responsive data visualization helps identify which state has the worst drivers. Road traffic safety is one of the major concern in the world. The road collision problem is acute since the number of victims are overwhelming and the situation is severe. Since the USA is the country on the wheels, we wonder how the situation is here.
This visualization can be viewed using phone or tablet as well.
You can play around the visualization and see what you can find.
Tracking and Tracing System of Agriculture
Usability Study and User Interface Design
This platform has already been used in China by hundreds of factories and farms. I joined the team in 2013 to provide advice and help improve the user experience of the system. I learnt a lot during investigation and interview, which became great asset of my future UX study. The screenshots above tell the improved interface.
MarketSmith Tools
Quality Assurance
This summer (2016), I was doing an internship as a QA in a company based in Hangzhou. I was in the MSTools team, which was cooperating with other companies to develop the MarketSmith Global. My major responsibility is to test the performance and give suggestions about user experience.
Right Search Engines for Travel Planning
Usability Study
To compare different search engines and evaluate their guidance for users, we aim at helping them make travel decision efficiently. When users are not familiar with their travel destinations and have no specific plan, they tend to start with using search engines to assist them find out places of interests. Specifically, we want to concentrate on how much valuable information they can get to build an initial picture of the destination by searching on different engines.
This is an interactive data visualization. The interface uses dynamic elements to show more information than can be presented in a single view, as Shneiderman’s formula: “overview first, zoom and filter, then details on demand.”
The topic is about the hottest movie Captain America: Civil War. The visualization is more like a movie guide which provides an intuitive wayto present the relationships and information of characters.

Mobile Membership Credit Management System
Mobile Application
This is a mobile software which manages the member credit for online shopping. I was the project manager in the team and worked with four other students who had different strengths. Basically, I took charge of the project planning, requirements analyzing, and testing. And I also did the front end design work. Above is how the mobile application looks like.
I learnt a lot from this team experience like how to manage time and coordinate teammates to work together even at the end of the semester when they were quite occupied and busy preparing for the examinations.
Digital Pic Frame for Nursing Home Residents
Usability Study
This design aims to improve life quality of people in nursing home and is more than a digital photo frame. Through investigation, we discovered that residents valued the family visits most and wanted more connection with their families. So the photo album idea bumped into our mind and we want to use an intuitive technology to assist residents share photos with their cared ones as well as their feelings.
The design process involving conducting interviews, creating personas and identifying problems, brainstorming individually, holding group meetings, and making prototypes, etc..
Residents in nursing house seek the warmth of home and our design provides such a channel to exchange photos without the need of much knowledge of technology. They will use a digital photo frame as device and in the mean time, their families will have application installed on their phones or computers to share photos and feelings together.


How can I add an attachment to a message?
To attach files to your email messages, do the following:
NOTE: When attaching files to your email message, they must be encoded and in doing so, will increase in size. The attachments sent with email have to be translated into a different format so that other email programs can read it. This type of transformation will add about 33% to the original size of the attachment. Therefore, due to the translation a 2MB attachment may turn into a 2.66MB email after encoding.

Analysis of Wario Ware: "It pushes the boundaries of game size and complexity, the speed at which we can adapt to new games, and game fictions, to the breaking point. Through these formal experiments, WarioWare demonstrates how complexity can be achieved through combining micro games into bigger games, the range of free play between fiction and rules available to designers, and the role of continuity in games."

Dr. Dre to be honoured by the Grammys for his trailblazing production work
"Dre breaks boundaries and inspires music creators across every genre"
Dr. Dre is going to be honoured by the Grammys for his trailblazing production work.

The Recording Academy announced on Friday (November 1) that it will salute the six-time Grammy-winning producer at the 13th annual Producers & Engineers Wing. Taking place on January 22, 2020, the event will kick off Grammy Week ahead of the 62nd annual Grammy Awards on January 26.
Deborah Dugan, President/CEO of the Recording Academy, called Dre “an influential force in music.”
“Dre breaks boundaries and inspires music creators across every genre,” she said. “His evolution as a producer solidifies him as a leader of the pack within our industry, and we watch in amazement as he continues to shape the future of music.”
Dr. Dre (real name Andre Young) is one of music’s most revered producers, engineers, and overall artists. Producing hits for everyone from Snoop Dogg, Eminem and Kendrick Lamar to Gwen Stefani, Alicia Keys and Mary J. Blige, he started his career in the early 1980s as a DJ for the World Class Wreckin’ Cru before becoming a member of legendary West Coast rap group N.W.A.
Delivering two classic albums in the form of ‘The Chronic’ and ‘Chronic 2001’, the 2018 Grammy Hall of Fame inductee founded Beats Electronics with Jimmy Iovine in 2008 before selling it to Apple for $3 billion in 2014.
Meanwhile, Eminem once nearly went on a huge tour with Snoop Dogg and Dr. Dre, according to 50 Cent.
Speaking to Big Boy TV, the rapper said the jaunt would have been worth “collectively, over $100 million (£80.2 million)” if it had gone ahead. But Eminem turned it down because he was concerned about not seeing his daughter Hailie for so such a long period on a lengthy tour.
