Ruby Classes
This week's techincal topic pertains to a critical concept in Ruby programming, which is the utilization of classes
So, what exactly are classes? Very simply, think of a class as a group of like items/things. Consider the animal kingdom, in which science separates groups of animals into classes based on their characteristics. These classes include birds, reptiles, mammals, and so on, with each class containing species that share similar characteristics. For example, laying eggs is a characteristic which all birds share, and is therefore one reason why birds are grouped together in the same class.
This concept is utilized in programming for much the same reason. By creating classes in our programs, we enable the creation of objects which are instances of these classes. These objects share many similar characteristics, and also behave alike in that they can perform the same methods.
Now let's go over a few topics so that you can create your own classes and use them in your programs!:
Creating a Class
Using code to form a new class is very simple and straightforward. Let's say that we want to create a new Bird class:
------------------------
Creating Instances of a Class
Excellent! Our Bird class now exists. So, now what? The purpose for creating any class is to allow yourself to use it later for the intention of creating an instance of that class. An instance of a class is an object which possesses all of the characteristics of the class. Sticking with our "bird" theme, let's say we want to create a new object of the Bird class, called Bob. We would do so with the following code:
------------------------
Variables and Variable Scope
Revel in your new creation of life! Bob the bird now exists thanks to you. But as it stands, he can't really do much because this essentially an empty class with no characteristics, and no methods for Bob to use. Furthermore, and additional instances that we create will be IDENTICAL to Bob, which seems kind of pointless right? We need to give this class some properties, and then we can use those properties to differentiate between different instances.
As we attempt to make the Bird class more unique, consider some potential qualities of birds that would be useful to define:
Color
Size
Can it fly?
So that our program can remember these various properties about Bob and his friends, we'll need to store their values inside variables. Remember, a variable is just a placeholder for a value, which can be accessed/manipulated during a program. The extent of that access/manipulation is contingent upon another importance concept in programming: variable scope.
Why is variable scope important? Sometimes we may not want all of our variables to be accessible by every part of the program at a given time. Placing restrictions on this access keeps our program structured, and also allows for secure expandability later on. There are four main types of variables that we use in the creation of our class:
- Global: A global variable is one that is the most accessible, including across all methods and all classes within a program. They are preceded by a $.
- Class: A class variable is available across different objects within a class, but not across different classes. They are preceded by @@.
- Instance: Instance variables can be utilized across different methods within a class. They are preceded by @.
- Local: And finally, a local variable is one that can only be accessed inside the method in which they were defined. Local variables are preceded with nothing.
Now that you understand variables, let's give the Bird class some properties (using an initialize method), and store those values inside some instance variables to be used later in the program:
----------------
Instance Methods
Now that Bob and any other instances of our Bird class have unique characteristics that are supplied by the user, let's make some methods that we can call on these objects to make them do things for us!
To do so, we'll need to code a few instance methods. These methods will only apply to instances of the bird class, and can be called at any given time. The code for doing so is as follows:
If you look at the end of the program, you'll see that we called the can_it_fly method by simply typing objectname.methodname. The result is:
CONGRATULATIONS! You've just created your first class, as well as an instance of that class with unique properties, and a method you can call on the instance to display a result. Go forth with your new knowledge, and keep it CLASSY!

In this section you will get familiar with the right-angled
library. You will see its possibilities on the
live examples. Also we provide the links to the sections with more details for each of the right-angled
aspects.
right-angled
is the library for constructing functional data tables (aka data lists, data grids). Also,
it has a very useful selection and filter models. They can work even without lists, but they go much better with them.
The main feature providing the basis for the library is unobtrusiveness seen in the following:
right-angled
provides directives instead of components whenever it’s possible.
There are only several components in right-angled
and they act just as visibility containers without any
additional markup. Again, it is 100% up to you how the app will structured and look.
right-angled
provides several useful services which
you can inject and use to implement your components easily). Nevertheless, we are sure that creating a new component
will give you more pleasure, than learning dozens of options and trying to style an alien one with the markup that
cannot be modified.
right-angled
, except angular,
is the e2e4 library created by us. This library
implements the functionality for the lists in abstract manner with no dependencies at all.
right-angled
To use the right-angled
library we should install it via npm by the following command:
npm install right-angled --save
Next, we import the RTModule
and add it to AppModule
imports array. Also, it is possible to
use the functionality part by part. For that there are such modules as RTListsModule
, RTSelectionModule
,
RTFiltersModule
and RTMiscModule
.
Below there is an example of the code which we will turn into the list. As you have noticed, it is the simplest angular
component with the template representing regular markup with the use of bootstrap library. The use of bootstrap
is not necessary, actually. The reason we have used it is just because of
its popularity among the software developers, so the sample markup looks familiar to most of you.
In order to turn the component into the list, we need to add rtList
directive in the template. This directive
takes one parameter – data request function. This function should return Promise
, Observable
,
or EventEmitter
with the resulting data. As in the example below, we inject AirportsService
class into our component and use its getAirportsList
method.
Our list already sends the sorting parameters in the request. But we need the way to change them through UI. In the example
below, we add rtSort
directive into the table headers template to do this. The component code doesn’t
require any changes.
rtSort
directive gets the string with the sorting identifier as a parameter. This identifier will be sent
to the server when requesting data. In the most obvious case, it can coincide with the column name. However, remember
about sql injection when developing backend!
In the example below, sorting will be made by click on column headers; holding Ctrl
allows sorting several
columns.
Our list does not look good when loading data. We can fix this situation using rt-list-state-progress
component.
This component will render the nested markup while data loading.
In the example below we add rt-list-state-progress
component with the div
inside which is styled
to display progress bar. Additionally, we add rt-list-state-done
component to display notification about
successful data loading. The code of our component has not been changed.
The same technique can be used to display specific content when there are errors, or no records loaded and so on. See more details here.
In the example below we add rtSelectionArea
directive into tbody
element specifying it as the
selection area.
Then we add rtSelectable
directive into tr
element specifying, that the row is becoming selected
element.
Moreover, with the use of angular
class
directive, we add the selected
class to
the table row, when the selected
property of the rtSelectable
directive becomes equal to true
.
The component code has not been changed.
Now the table reacts to the following actions:
Ctrl
held selects clicked element keeping the previous selections.Shift
held selects the sequence of the elements from the last selected element to the
clicked one.↑
key selects the previous element. Or it selects the first element in the list, if there
were no earlier selections.
↓
key selects the next element. Or the first element in the list, if there were no earlier
selections.
Ctrl + ↑
selects the first element in the list.Ctrl + ↓
selects the last element in the list.Ctrl + A
selects all elements in the list.Tab
and Shift + Tab
moves you up or down the list.With the help of the selection it is possible to implement multitude of useful things: displaying master-detail, inline edit, grouped lists, context menus, and so on. And it can be also used without the lists at all. All details are available in the Working with selection section.
In the example below we add buttons for data loading, canceling requests and resetting list parameters. These buttons use
the additional rtList
methods in their click
event handlers.
In the example below we add the second list to the template, which is assigned to the same component. Then we add the paged pager and buffered pager components, described in the section about the paging, into these two lists
In brief, there are several utility components and directives in right-angled
library, which can be used
to construct a reusable and functional pager component. Such a pager can be used for all the lists in your project. This
is particularly what we did in the section about the paging using
here its result.
We also change the data fetching function from getAirportsList
to getAirportsPagedList
, in
order to get the data with the paged structure.
Pay attention to the fact that reset
button now resets the paging settings also.
In the below example, we add two inputs to filter the data in the list. The component template in this case is just regular HTML markup. At the same time, the component code looks interesting.
First, we annotate the added airportName
and countryName
properties by the @filter
decorator.
Second, we add the onListInit
event handler, in which we register our component as a filter by calling registerFilterTarget
method of the received RtList
service.
As a result, we get the following:
airportName
property it is its initial value that is null
. And for the countryName
property it is the
"Iceland" string specified through the @filter
decorator additional settings
In the example below you can see that we add the rtDemoSerializeToQueryString
directive, implemented in
Persist lists state section, into the list template.
Now the state of list parameters will be reflected in queryString
on every data request. If you change any
of the list parameters and reload browser page, the values of the list properties will be restored from queryString
parameters.
We also have used the loadOnInit
option of the rtList
directive to switch off the automated
data loading and not to write anything to queryString
before you read this section.
Of course, the reflection in queryString
is not the only way to work with the list state. You can get more
details about state persistence in Persist lists state section.
Instead of implementing the fully functional backend, we will use a simple json
-file with the data about
99 airports, which we will process in AirportsService
with the help of the lodash library.
To work with the simple lists we have implemented getAirportsList
method. This method gets single parameter
which implements AirportsListRequest
contract and specifies filter and sorting parameters.
This method returns Observable
with first five Airport
objects from the whole collection, since
99 records is too much and we do not have paging in the several first examples of our quick tour.
To work with paging we have implemented getAirportsPagedList
method. This method gets single parameter which
implements AirportsPagedListRequest
contract. AirportsPagedListRequest
extends AirportsListRequest
contract and adds two additional properties:
skip
property specifies the number of records to skip on next data request.
take
property specifies the number of records to take on next data request.
This method returns the object which implements AirportsListResponse
contract. Such object contains array
of airports and the totalCount
and loadedCount
properties, which specify the total number of
records regardless paging and number of records loaded as a result of the executed data request.
You can see below the source code of the mentioned classes and interfaces below.

This protocol is for northern blotting/dot-blotting to detect specific
RNAs via chemiluminescence, using biotinylated DNA oligo probes. Gels etc
are optimized for detection of 0.5-4kb mRNA transcripts.
Much of it is adapted from ULTRAhyb-Oligo and Brightstar BioDetect
commercial protocols, or from Nonisotopic Probing, Blotting, and
Sequencing (Kricka, ed; chapter 5).
For abundant RNAs, it is possible to reduce the lengths of the (many)
hybridization, wash and block steps while still obtaining a clean blot
with low background - test probes and sample the slow way first.
Ingredients
-
1X TBE, 0.5X TBE. Make from 10X stock.
-
RNase-free agarose
-
Gel casting, running and electroblotting equipment (BioRad Minigel system,
Biorad Criterion or Protean blotter)
-
RNA ladders: ThermoFisher RiboRuler HR (#SM1821) is good for 200-6000nt mRNAs.
DynaMarker® Prestain Marker for RNA High (Biodynamics #DM260) is a prestained
ladder made of polysaccharides useful for seeing the gel run and or successful
membrane transfer, but it runs larger than advertised length on TBE-agarose gels.
-
Positively charged nylon membrane (BrightStar-Plus Positively
Charged Nylon Membrane, or Roche 11-209-299-001, or Bio-Rad Zeta-Probe #1620154)
-
UV crosslinking box, e.g. Stratalinker.
-
ULTRAhyb-Oligo buffer (Life/ThermoFisher AM8663)
-
DNA oligo probes: 5’ biotinylated, 36-45nt long, 60-75C hybridization
temperature, 45-65% GC-content, in
10uM working solution. Or use biotinylated oligo-dT
probes (Promega #Z5261) at 5 pmol/uL for mRNA.
-
Stringency wash buffer: 2X SSC (300mM NaCl, 30mM sodium citrate, pH
7.0), 0.5% SDS. Make from 20X SSC stock (Life/ThermoFisher, AM9770).
-
NB strip buffer: 0.1X SSC, 0.5% SDS.
-
Streptavidin-AP conjugate (Life/Thermo Fisher #S921)
-
CDP-Star® Luminescent Substrate (0.25 mM Ready-To-Use), (Life/ThermoFisher #T2146)
-
Wash buffer: 1X PBS, 0.5% SDS. Make a 5X concentrate with 5X PBS and 2.5% SDS.
-
Blocking buffer: 1X PBS, 0.5% SDS, 0.1% I-Block reagent.
-
Assay buffer: 0.1M DEA (diethanolamine), 1mM MgCl2, pH 10.0.
Note: the BrightStar BioDetect Nonisotopic Detection Kit (Life/ThermoFisher AM1930),
contained CDP-star, Strep-AP, 5X wash buffer, 1X blocking buffer, and 10X assay buffer, but was not
produced after 2014.
Make wash, block and assay buffer fresh every month.
Be fastidious about cleanliness and avoiding degradation!
-
Use RNAse-free equipment and solutions to run gel and transfer so
you get a clear single band, and do not degrade your sample.
-
Only ever touch the membrane with forceps, i.e. not with your skin,
sweat, etc, to avoid background.
Dot Blot
To check if your probes and buffers are working without running a gel.
- Gently pipette 10uL of each RNA sample onto positively charged nylon membrane
on vacuum (fritted glass plate). Dry membrane.
Northern Blotting
-
Cast a 1.5% agarose gel in 1X TBE buffer with 1:10000 SYBR safe and
allow to set.
-
Put 1uL (or other measured amount) of each RNA sample into total
10uL of 1X RNA loading buffer (NEB). Heat the tubes at 65 C for 5 min
to denature RNA and then immediately place the tubes on ice.
-
Load samples on the gel along with 5uL RNA ladder/markers. Run the gel
in 1X TBE buffer at 100 V for 30min, or until the first bromophenol
blue dye reaches the bottom of the gel.
-
Turn off the current, remove the gel, and transfer the RNA onto a
positively-charged nylon membrane. Use a pencil to mark the sample
side of the membrane. Assemble gel sandwich according to picture on blotter instructions
(RNA is negatively charged, so gel near negative electrode and
membrane near positive electrode), use a standard Western blotting
apparatus with 0.5X TBE buffer at 1 amp for 1 h. Trim off the
portions of the gel that do not contain the samples to decrease the
size of the membrane and use of smaller amounts of reagents in
subsequent steps.
-
Crosslink RNA to the membrane by UV at 300 mJ/cm2; keep the
membrane wet during crosslinking. Then dry the membrane; sample side
faces up throughout.
Hybridization
-
If necessary, reheat ULTRAhyb-Oligo to 42-68 C to dissolve all
precipitated material.
-
Prehybridize the blot for 10 min at 42 C with gentle agitation (incubator
at 42 C with 40rpm shaking). Use 1 mL ULTRAhyb-Oligo Hybridization
Buffer per 10 cm2 of membrane; volumes shown here are for
minigel-sized blot, about 100 cm2. Be certain that enough solution
is present to keep the membrane uniformly wet for all subsequent steps.
[step:prehyb]
-
Add 5 nM of the end labeled oligonucleotide (0.5 ul of
10 uM working solution per mL of buffer). Since it is
important that undiluted probe solution does not touch the membrane,
pour the ULTRAhyb-Oligo solution from the prehybridization into a 50
mL conical tube, add the labeled probe, mix by swirling, and then
immediately pour the solution back into the container with the blot.
-
Hybridize overnight (6-24hr) at 42 C with gentle agitation. It may be
possible to reduce the hybridization time down to 1hr for detection of
relatively abundant RNA.
-
Wash the blot 2x30 min. Pipette off hybridization solution
and save in 10mL tube, this can be reused multiple (~5) times.
Immediately pour at least 50 mL stringency wash buffer onto the blot
and incubate at 42 C for 30 min with gentle agitation. Repeat with fresh
stringency wash buffer.
Detection
-
Measure the surface area of your membrane to determine the amounts
of the washing and assay buffers needed. For example, for a 10 x 10 cm membrane (100
cm2), 100 mL of washing buffer and 30 mL of assay buffer are
needed (the volumes below are given for a 100 cm2 membrane).
Place the membrane sample side up in a plastic box of similar size,
at room temperature on a rocking shaker at medium speed (10-20 rockings/min).
Do not allow the membrane to dry throughout the entire procedure.
-
Wash the membrane 2 times, 5 min each, in 20 mL 1X washing buffer.
-
Wash the membrane 2 times, 5 min each, in 10 mL 1X blocking buffer.
-
Wash the membrane once for 30 min in 20 mL 1X blocking buffer.
-
Incubate the membrane for 30 min in 10 mL of conjugate solution
(10 mL blocking buffer plus 1 ul of streptavidin-alkaline phosphatase
conjugate).
-
Wash the membrane once for 15 min in 20 mL 1X blocking buffer.
-
Wash the membrane 3 times, 15 min each, in 20 mL 1X washing buffer.
-
Wash the membrane 2 times, 2 min each, in 15 mL 1X assay buffer.
-
Incubate the membrane in enough CDP-star solution to cover, about
1mL, for 5 min. Rotate by hand to make sure that the solution evenly
covers the entire membrane.
-
Take out the membrane with forceps. Let the excess of CDP-star
solution drip off, place the membrane on clear plastic wrap and
wrap, ensuring no air bubbles are left.
-
Image the membrane on the Chemi-doc or other digital imager. Use
chemiluminescent detection with signal accumulation mode, for
example 45 images, 900 s. The CDP-star reaches peak light emission in
2-4 h, and the light emission persists at the high level for several
days, so you may get a better image by waiting an hour
to image. SYBR safe also tends to transfer to the membrane with
rRNA, sometimes enough to be seen by the naked eye, but is
visualizable on Cy3 channel; unfortunately Xylene Cyanol
is also transferred, visible as a lower-molecular
weight bright blur on this channel so tRNA is not visible.
Stripping and re-probing
Membranes may be stripped and re-probed multiple times (at least 4);
they can be left in wash or block solution overnight, or frozen in
plastic wrap at -20 C for weeks.
-
Remove membrane from plastic wrap, place membrane in a plastic tray
that can survive 100 C liquids, covered by a minimal amount of NB
strip buffer. Do not dry membrane, which may stick previous probes
to membrane.
-
Twice: Heat 50mL NB strip buffer to boiling, in the microwave. Empty
previous liquid, and pour boiling strip buffer over membrane
in tray. Allow to cool to room temperature on rocker, about
15 minutes.
-
Restart hybridization with new probes and continue as before.

CSM offers group tutoring to all students in these four classes. Students are sorted into one of the timeslots of their preference. Session are held weekly, in the same room typically in Soda or Cory, for 1 hour to 90 minutes during times ranging from 9:00 AM to 7:00 PM. Mentors will go over a worksheet in section with extra problems to be worked on in groups. Homework, lab, and project help will not be provided during these sessions.
Students enrolled in group tutoring are eligible for 1 unit of P/NP credit. Grades are based on attendance. Those attending the session for a grade are required to attend 90% of weekly assigned sessions.
More in-depth expectations here.
Check out our Scheduler website around 2 weeks into the semester to sign up! Create an account, confirm your email, select a class, and enroll in a empty section.
Yes. CSM's biggest priority is reaching out to as many students as we can. However, if you aren't enrolled on Telebears, you will still be required to regularly attend the specific section you are assigned to.
Yes! Each student can receive 1 unit of P/NP credit. We will provide you the appropriate CCN when the time comes. You are not required to enroll. You must attend 90% of your assigned weekly sessions in order to pass.
Feel free to email us at<EMAIL_ADDRESS>if you have any questions or concerns!


The Problem
The definition of done hinges completely on erroneous homosapiens.
-
We get elbow-deep into code we don't fully understand.
-
We sometimes justify shortcuts.
-
No matter how hard we fight it, we remain sentient beings.
We've all been there, where we're tired of writing tests and justify our shortcomings to ourselves.


You Can Count on Me
You Can Count on Me is a movie starring Laura Linney, Matthew Broderick, and Amy Ryan. A single mother's life is thrown into turmoil after her struggling, rarely seen younger brother returns to town.

Hey there! If you've found your way here, then I'm pretty sure you want to know more about me so let's get started. I am currently a junior at Cornell University and I'm studying Information Sciences with a focus on User Experience and Networks/Crowds/Markets. So far, I have learned about basic programming, objects-oriented programming, front-end web development, and back-end web development. I really enjoy working with computers and enjoy figuring out more ways to interact with them. Below, I have included some projects I've worked on that can demonstrate my knowledge.
This was a group project done for an on-campus client named Mediocre Melodies. This project tested my creativity, requiring me to cater to design choices of the client while maintaining thematic unity and balancing unique design with user experience and functionality. I also learned how implement a form which will return results to the president of the student committee when submitted. Most importantly, this project also served to improve my leadership and teamwork abilities.
Miralrio Landscaping was another group project done for a client where I developed my database skills. It incorporated the use of php and SQL to include functions that customers might find helpful while reducing work for the client. Some functions include the quotes page and the tagging of pictures. This project also allowed me to demonstrate clean, simple, UI and focus more on user experience.
An independent project done for class that demonstrates my backend knowledge. I was required to create a site that allowed uploading, deleting, and tagging of pictures from the database while logged in. The login function also allowed me to experience a little bit about hashing, security, and sessions. Test it yourself! (login:seedData,pass:12345)
Click to learn about my experience with each:
I have 3 years of experience in Java from highschool and from UIL competitions. I also have one semester of more advanced Java from a college class about objects-oriented programming where we worked on many different topics. While it has been a long time since I have wielded Java, my solid foundation in this language will allow me to work with it seamlessly.

| Assembly Language Assembly language uses easy-to-remember commands that are more understandable to programmers than machine-language commands. Each machine language instruction has an equivalent command in assembly language. For example, in one Intel assembly language, the statement Ħ°MOV A, BĦħ instructs the computer to copy data from location A to location B. The same instruction in machine code is a string of 16 0s and 1s. Once an assembly-language program is written, it is converted to a machine-language program by another program called an assembler. Assembly language is fast and powerful
because of its correspondence with machine language. It is still difficult
to use, however, because assembly-language instructions are a series of
abstract codes and each instruction carries out a relatively simple task.
In addition, different CPUs use different machine languages and therefore
require different programs and different assembly languages. Assembly
language is sometimes inserted into a high-level language program to carry
out specific hardware tasks or to speed up parts of the high-level program
that are executed frequently. |

#include <array_ops.h>
Reverses variable length slices.
This op first slices input
along the dimension batch_dim
, and for each slice i
, reverses the first seq_lengths[i]
elements along the dimension seq_dim
.
The elements of seq_lengths
must obey seq_lengths[i] <= input.dims[seq_dim]
, and seq_lengths
must be a vector of length input.dims[batch_dim]
.
The output slice i
along dimension batch_dim
is then given by input slice i
, with the first seq_lengths[i]
slices along dimension seq_dim
reversed.
For example:
# Given this: batch_dim = 0 seq_dim = 1 input.dims = (4, 8, ...) seq_lengths = [7, 2, 3, 5]
# then slices of input are reversed on seq_dim, but only up to seq_lengths: output[0, 0:7, :, ...] = input[0, 7:0:-1, :, ...] output[1, 0:2, :, ...] = input[1, 2:0:-1, :, ...] output[2, 0:3, :, ...] = input[2, 3:0:-1, :, ...] output[3, 0:5, :, ...] = input[3, 5:0:-1, :, ...]
# while entries past seq_lens are copied through: output[0, 7:, :, ...] = input[0, 7:, :, ...] output[1, 2:, :, ...] = input[1, 2:, :, ...] output[2, 3:, :, ...] = input[2, 3:, :, ...] output[3, 2:, :, ...] = input[3, 2:, :, ...]
In contrast, if:
# Given this: batch_dim = 2 seq_dim = 0 input.dims = (8, ?, 4, ...) seq_lengths = [7, 2, 3, 5]
# then slices of input are reversed on seq_dim, but only up to seq_lengths: output[0:7, :, 0, :, ...] = input[7:0:-1, :, 0, :, ...] output[0:2, :, 1, :, ...] = input[2:0:-1, :, 1, :, ...] output[0:3, :, 2, :, ...] = input[3:0:-1, :, 2, :, ...] output[0:5, :, 3, :, ...] = input[5:0:-1, :, 3, :, ...]
# while entries past seq_lens are copied through: output[7:, :, 0, :, ...] = input[7:, :, 0, :, ...] output[2:, :, 1, :, ...] = input[2:, :, 1, :, ...] output[3:, :, 2, :, ...] = input[3:, :, 2, :, ...] output[2:, :, 3, :, ...] = input[2:, :, 3, :, ...]
Arguments:
input.dims(batch_dim)
and max(seq_lengths) <= input.dims(seq_dim)
Optional attributes (see Attrs

Returns:

A demonstration of how you can combine the different RGraph chart types onto a
single SVG
tag. Here a Bar chart is being combined with a filled Line
chart - a common combination. Both charts are using the labelsAbove
option and they both also have a center X-axis
.
The Line chart marginInner
property has been set such that the points on the Line
chart line up with the center of each section of bars.
The Line chart is filled with a semi-opaque color so that you can see the bars behind the line.
Both the Line and Bar have the labelsAbove
property stipulated so that there are
labels above each point/bar that show you the exact value.
When the screen size is smaller the size of the text is reduced and the CSS
float
on
the SVG
tag is removed.
  , Put this where you want the chart to show up:

This is the code that generates the chart - it should be placed AFTER the
div
tag:

I love coding because there are so many interesting things I am able to do. Lately, I've grown interested in machine learning and especially natural language processing. Imagine being able to just parse a document for meaningful information. Oh, the power!!
Listed below are a few things that I find interesting (and that use ML and/or NLP) and will be working on in the next few months:
- An Alexa skill
- Scraping data from ELMS
- Facial recognition
- Video transformation in real time

The web consits of:
-HTML(Hyper Text Mark-Up Language)
-Hyperlinks
-30 billion pages
HTML includes:
-Text Content
-Markup
-References to other documents, i.e. video & images
Mark-Up is the way the code is written. It contains the opening and closing tags with the contents between the tags. This is called the Element.
Example: <Opening Tag>Contents<Closing Tag>
Attributes allow us to put hyperlinks or images into documents.
-hyperlink attributes use the anchor= < a > tag; an example of this would be for Google
-images are also tagged similarly using the < img > tag; an example of this would be for
In HTML, all lines of text are written on one line unless they are forced onto multiple lines using Break Tags or Paragraph tags
-Break Tag= < br > :This tag start text on a new line
-Paragraph Tag= < pr >: This Tag needs an opening and a closing tag. This tag has content inbetween the tags.
Inline tags break line ands start new ones.
Block tags create an "invisible box" around text which has depth and height.
Example Inline tags = Bold Tags, Emphasis tags and Image tags.
Example of Block Tags= Paragraph tag.

1st Wave of Coffee The first wave of Coffee dates back to the 1800s when this beverage consumption started to grow exponentially, brands such as Folgers and Maxwell House are an example of the forerunners of this wave. Quality was not important as price in this wave. A great innovation in this wave was the Vacuum packing which took the air out of the coffee tins to maintain the freshness of the beans. There was zero knowledge about the origins of the coffee or processes. The focal point of this wave was to make coffee a widely consumed product, to become a mass market product which could be found in every household. An innovation which marked this first wave was the invention of instant or soluble coffee which made the preparation of coffee a fast and convenient way to make this beverage.
2nd Wave of Coffee The second wave of Coffee started in the 1970s especially with the birth of the now coffee giant Starbucks which understood that people needed to see coffee as a whole experience rather than just as a beverage. Customers started expressing the desire to know more about the origins of their coffees and the unique roasting styles, thus bringing the start of the specialty coffee era. The most important characteristic of this wave, is that the coffee experience evolved from just a quick caffeine fix to a point of encounter, thus making coffee shops a point where people went to have social interactions and giving coffee a special place in the social dynamic.
3rd Wave of Coffee The third wave of Coffee as a term was first used by Trish Rothgeb back in 2002 published in the Roasters Guild Publication defining the three Coffee movements as “waves”. This wave is characterized by a market made up of much more sophisticated coffee consumers, that are interested in having an exceptional cup of coffee rather than just a cup of who-knows-where this came coffee from? An important feature of this wave is that of the Specialty Coffee which was a turning point on the coffee industry. The quality of the coffee became very important, and with it, a lot of other aspects of the coffee such as the formation and professionality of the barista, the traceability of the coffee beans, micro roasters and fair-trade coffee just to mention a few.
Affogato
Traditional Italian drink which consists of a scoop of gelato (ice-cream) and a shot of espresso.
Americano
It’s a type of Coffee drink prepared with a shot of espresso and then diluted with hot water.
Arabica
Coffea Arabica or just Arabica is also known as the Arabian Coffee. This is one of the two main species of Coffee, it
is regarded as the one with a rich and complex organoleptic profile and better quality, no wonder why it represents
approximately the 60% of the worlds coffee production. Arabica is grown all over the world, in regions such as
Africa, Latin America, and Southeast Asia. It is thought to be the first type of Coffee to be cultivated in the
world.
Aroma
Aroma is the olfactory aspect of the sensorial analysis coffee. The Aroma of each Coffee is composed by around 800
substances, guess that’s why we love it so much! The Specialty Coffee Association analyses the aroma of ground coffee beans to judge its grade.
Barista
Barista is a remarkable profession which consists of having the knowledge to prepare the perfect beverage for every
customer. Barista is the great guy or gal that we have to thank for lifting us up in the morning.
Bean
The seed of the coffee cherry is better known as “The Bean” which is later roasted and ground to make
that delicious beverage we all love, especially in the mornings.
Bitter
Bitterness on coffee is a characteristic of the flavor which is harsh and not sweet, for example; Dark Roasts are
made intentionally to give a bitter taste.
Body
The body of the coffee is intended to explain the texture of the beverage, it ranges from thin, delicate, juicy,
syrupy and heavy.
Bloom
The process of pouring a small amount of water to the coffee grounds to prepare the process of extraction saturating
and degassing the grounds.Normally freshly roasted coffee contains CO2 and other kinds of gases for about three weeks,
the blooming process is intended for liberating these gases and thus achieving an optimal aroma and flavor.
Brewing Ratio
It is expressed as the ratio of ground coffee mass to water mass used during extraction. It can be expressed with the
European standard which is g/l(grams per liter/ e.g. 60g/l for pour-over coffee) or with the American standard
1:x(e.g. 1:16 it’s the same as 60g/l)
Brewing temperature
One of the most important parameters during the extraction phase is the water temperature. It substantially affects
the organoleptic characteristics of the coffee cup. Usually, temperatures between 92 ° C and 98 ° C are
preferred: low temperatures emphasize the acidity and the fruity scents, while higher temperatures mostly extract the
chocolatey and toasted notes up to the bitter. It is possible to precisely control the water temperature by using
electric boilers with temperature setting or special thermometers for traditional boilers.
Brewing time
It refers to the period of time in which the water comes in contact with the ground coffee, this is when the
extraction happens.There is an optimal brewing time for every method, check out our brewing guides for more details.
Bright
The acidity flavor in coffee is described as bright, it is very common in Central American Coffees such as Guatemala,
Colombia, Costa Rica, Kenia, and Ethiopia. This acidity or bright can be tasted at the tip of your tongue.
Briny
Briny is a salty flavor caused by the excessive exposure of Coffee to heat.
Caffeine
Main natural alkaloid present in coffee, responsible for the stimulating and psychoactive effect of this drink. From
a sensorial point of view, it gives bitter notes to coffee, which is why the Robusta, which contains more caffeine
than Arabica, is characterized by a more marked bitterness. The amount of caffeine contained in the coffee beans
varies according to the cultivar, however, the content of this alkaloid extracted in the drink depends substantially
on the extraction method and on the contact time between coffee and water.
Cappuccino
A traditional Italian drink made from an espresso shot with foamed milk.
The tradition says that there should be a big patch of milk foam surrounded by a thin brown circle.
The Latte Art technique foresees the decoration of the cappuccino with diverse designs obtained thanks to a particular mastery when
pouring the foamed milk.
Chemex
The Classic Hour-Glass coffee maker crafted by the german inventor Peter Schlumbohm in 1941. This particular coffee
maker brews coffee by the pour-over method and it utilizes paper filters. The resulting cup of coffee is
characterized by being very sweet and aromatic.
Cherry
The coffee plant produces a fruit which is very similar to a cherry, and inside it contains the bean.
Coffee berry borer
The berry borer is a beetle-like insect native to Africa which is causing a lot of problems to coffee farmers all
over the world because it infests the cherries ruining the beans.
Coffee leaf rust – Coffee rust, or “la roya”
The Coffee Leaf Rust is a fungus that is affecting the coffee plantations in Central and South America,
causing the plant to lose its leaves thus rendering the plant unable to produce fruits.
Cold Brew Coffee
Cold brew is basically a type of coffee that instead of being brewed with hot water it is done with cold water at a
very slow rate, this method can be drip or immersion. Cold brewed coffee is much less acidic and it is characterized
by a particular flavor development. The cold infusion method exalts all the characteristics in the coffee, both
positive and negative. this is why it is fundamental to use a high-quality coffee to make sure that the resulting cup
is a great one.
Cold Drip Coffee
Cold Drip is an extraction method which consists of leaving cold water dripping over the grounds of the coffee at a
slow rate for many hours, resulting in a brew with many different characteristics as those of hot water coffee
extraction methods.
Cortado
Cortado literally means “cut” in Spanish, it was born in Argentina and has now become popular all over
Latin America, Spain, and Portugal. It’s an espresso with a little dash of milk and can be also prepared with
condensed milk.
Crema
The foam that rests on top of an espresso cup that stems from the dilution of the CO²
gasses from the roasting process into the hot pressurized water used for brewing.
It's color ranges from golden to dark-tan.
Cup of excellence
Cup of excellence or (COE) A contest to decide which is the best coffee grown in a particular country. The COE uses
the Specialty Coffee Association protocol to grade the coffee. Only coffees with a grade of 90/100 or higher can
obtain this qualification. (Approximately 10% of specialty coffee)
Cupping
Also known as the brasilian-tasting method. It is a tasting process utilized by the coffee professionals to test the
coffee’s qualities. This tasting method consists of steeping coarsely ground coffee with hot water in shallow
bowls, then the tasters sniff the coffee to smell the aroma and proceed to slurp the coffee and move it around their
mouths to feel all the flavors.
Current Crop
A term indicating the harvest of the current year emphasizing the freshness of the product. Only these coffees are
allowed for the Qualification of Specialty.
Dark Roast
A type of roast that takes a longer time, normally the coffee beans will lose a lot of their properties and become
more bitter tasted.
Earthy
A characteristic of some coffees who tend to taste like earth or soil, normally Indonesian coffees have this kind of
flavor, but many others do so too.
Espresso
A coffee beverage of Italian origin, normally a very strong which is regularly drunk in small quantities. Traditional
espresso has very solid rules: 7 grams of ground coffee to obtain 30 ml of infusion in 25 seconds.
Extraction
The process of drawing the properties of ground coffee with hot or cold water.
FairTrade
A program intended for the protection of the farmers that certifies that the coffee farmers had been paid a fair
price for their coffee.
Filtered coffee
A Coffee beverage that distinguishes itself from espresso by containing more water in the brewing ratio, and the
absence of the crema. The regular dose is the “mug” (aprox. 235ml) much larger than a 30 ml espresso cup.
Filter coffee can be obtained with different methods such as immersion (French press) or pour over (Chemex).
Flat White
An espresso with a high quantity of steamed milk.
French Press
Also known as coffee plunger or caffetierè, is a coffee maker invented by the Italian Ugo Paolini in 1929.
Green Beans
Coffee Beans before the roasting process.
Grind size
In order to correctly extract all of the coffee flavors and the caffeine, coffee beans must be ground. The ground
measure varies according to the brewing time and the extraction method and the utilized tools.
Hand picking
A harvesting method which consists of selecting only the mature beans by hand, it guarantees a much higher quality.
This is the only accepted method by the Specialty Coffee Association.
History of Coffee
Early evidence says that coffee was first discovered in Ethiopia and then exported to Yemen. If you want to know more
you can read the wikipedia article about the History of Coffee.
Immersion
As its name implies immersion is an extraction method which consists of immersing the coffee grounds in water and
letting the water extract the flavors and aroma. One well-known immersion coffee maker is the French press, also
there’s a cold brew immersion method.
Kopi Luwak
Also known as “World’s most expensive Coffee” is a type of Coffee made with the help of a little
cat-like animal named Asian palm civet (Paradoxurus Hermaphroditus) native to southeast Asia. Coffee cherries are
eaten and then excreting the partially digested beans, and theoretically, it makes the flavor of the coffee even
better. Given the difficulty of finding the civet droppings in the wild, and having to collect them by hand the price
is inflated so much that it has been renamed as the most expensive coffee. The problem with this coffee is that
because of its high demand, some farmers started caging the animals and feeding them only coffee cherries thus
restricting their diet and making them suffer in the process, that’s why many activists have called out
companies that sell that coffee and asking the public to not consume this product.
Latte
Latte literally means milk in Italian, and this beverage is made with a shot of espresso and a lot of latte!
Latte Art
The art of decorating coffee drinks with steamed milk, it only serves aesthetical purposes and does not change the
flavour whatsoever.
Lungo
An espresso with a longer extraction time, it contains more water so its flavor is less strong than the regular
espresso.
Macchiato
Macchiato means stained in Italy, it consists of a shot of espresso topped (stained) with a dab of foamed milk.
Micro-lot
Artisanal coffee that comes from a single farm, regularly of a higher quality than the standard.
Mocha
It is a drink composed of a shot of espresso, chocolate syrup, steamed milk, and sometimes whipped cream.
Moka
The traditional Italian home coffee maker, it was invented by Engineer Alfonso Bialetti in 1933, this classical
coffee maker can be found in most Italian households and all over the world.
Natural/dry processing
It is a process in which the coffee cherries are left to dry under the sun before being pulped and de-hulled. The
result is a very sweet coffee compared to the washed process.
Portafilter
The filter basket and handle on an espresso machine.
Pour-over coffee
An extraction method invented in Germany by Melitta Bentz which consists of pouring water in a steady and slowly
manner over a filter cone which contains the ground coffee.
Puck
The small black disk created when the coffee is compressed in the portafilter, it is called puck because it looks
like a hockey puck.
Ristretto
Ristretto means restricted in Italian, it is an espresso pulled short, less water quantity, creating a
super-concentrated shot of espresso. To be considered a ristretto it can have a maximum of 20 ml of drink.
Roasting
The process of heating the beans to be able to extract the great flavors of the bean. During the roasting process,
the coffee beans tend to lose most of their humidity they then start getting brownish and depending on the roasting
time the darker they will get. This process is vital to the development of the flavors that will then be extracted on
a cup.
Roast date
The roast date is used to keep an eye on the freshness of the beans, a rule of thumb is that roasted coffee lasts
fresh for about 2-3 months, depending on the type of roast and the way it is stored, but if you want to be more
precise you should ask your roaster directly how long it stays fresh.
Roasting Degree
Roasting degree refers to how light or dark is the bean after the roasting process, there are many types of roasting
such as first crack, city roast, full city, second crack, Vienna, French roast, charcoal, etc..
Roast profile
A roast profile represents the effects of how the airflow and the heat are controlled during the roasting which
determines how quickly the beans arrive at a roasting degree.
Robusta
The second of the two main species of coffee, its scientific name is Coffea Canephora and it is characterized by
having a smaller and rounder bean. Its organoleptic profile is less rich and complex compared to that of the Arabica.
Usually, it is used in mixes intended for espresso because it gives a strong bitter note and a more consistent crema.
It has a higher index of caffeine than arabica and because of this motive, it is usually not used for the filter
coffee. From a botanical point of view, the Robusta plant is more studier and more productive than its similar
Arabica.
Q Grading
Q grading is the process of the coffee being analyzed by professionals called Q graders, whose job is to evaluate the
coffee and in that way determine its quality and its market value.
Seasonal coffee
Coffee is an agricultural product with its own seasonality, that varies depending on the producing countries. A
seasonal coffee refers to the small/medium production lots. Because its processes are less industrialized and
normally a higher quality it means that these beans will not be available all year long. Seasonal coffee is different
from commercial coffee because commercial coffee has such great volumes that it can be available all year long.
Semi-washed honey process
This style of processing the coffee which is a mix of the dry processing and the washed these terms often refer to the same style of processing, where the first stages of the above are followed up until the cherries are pulped. Then, instead of fermenting the coffee in tanks, it is sent to be dried while the mucilage is still intact and stuck to the seeds. As the seeds dry, the mucilage loses a good deal of moisture but can contribute a greater degree of sweetness to the seeds (perhaps because less fermentation is taking place, meaning fewer sugars are being consumed by microorganisms). Once dried, the seeds may be washed to remove the stuck on pulp, or simply proceed to de-hulling. The green coffee seeds may also be dried again to reach the desired moisture content, as drying coffee in this state can take longer than the washed process. This process can also introduce complications that lead to flavor degradation, including mold growth, rot, and pests which are attracted to the sweet-tasting mucilage as it dries in the open air. These coffees must be carefully attended to during drying to properly maintain their flavor.
Single Origin
A type of coffee which is not a blend, to be considered single origin it has to come from only one producing country,
sometimes from a specific region or plantation
Syphon
A coffeemaker that utilizes vacuum pressure and a series of containers for brewing the coffee.
Specialty coffee
For a Coffee bean to be qualified as “Specialty” it has to be graded at least 80 points or more out of
100, this grading system was invented by the (SCA: Specialty Coffee Association) and it is used on green beans, so
this means that the grading is done with the raw material and it does not account for any post-processes such as
roasting.
Strip picking
A harvesting method which consists in stripping all the coffee cherries in a branch, usually also the leaves. In this
way, the harvest is not homogeneous because alongside the mature cherries there will also be unripe and over mature
cherries. This method is usually used for massive plantations with low quality. Strip picking can be done by hand or
with mechanical devices made for this purpose.
Tamper
A device that is used to press the ground coffee into the coffee basket to prepare it for extraction.
Terroir
Terroir is a French expression that comes from terre “earth”, it means a well-defined area and the set of
all the environmental characteristics that affect a crop or a product. It is also used in other industries such as
wine, agave, tomatoes, chocolate, maple syrup, and cannabis. It includes conditions such as type of soil, average
temperature, elevation, atmospheric pressure, annual rainfall, amount of sunlight, etc…
Terroir is a very important characteristic when during the Specialty Coffee grading process.
Trigonelline
Another natural alkaloid present in coffee, it is responsible for the diuretic properties of this drink.
Old Crop
A term indicating the harvest of the previous year. This coffee can still be roasted and consumed but its
organoleptic profile will be much poorer than a Current Crop.
V60
V60 is Hario’s signature drip brewer, it is name comes from the 60-degree angle of the cone’s profile.
Wet/washed processing
This method involves using water through most of the steps of Coffee processing, and it is considered to be the best
method to achieve high-quality coffees.
AW = Await the allotted time
FE = Finish Extraction at the alloted time
FP = Fast Pour of water on the method
PI = pre-infuse or bloom the coffee for the allotted time
RS = Rao spin, spinning the method to swirl the coffee bed and increase the extraction by forcing the coffee to form new flowing paths
SP = Slow Pour of Water on the method
Choose your skill level according to your comfort with using different methods,grinds and recipes.
You don't know much about coffee but is willing to take the first plunge in this amazing world. You will be directed to the easiest methods.
You are already more than a neophyte, and already has more than one method, you will be directed to percolation and infusion methods to help improve your skills.
After trailing the unknown coffee realms, you have arrived at it's fringe, beyond here it's all about experimenting with different grind profiles, machines and methods.
We won't limit your creativity, which means you can see whatever you feel like. The world is your oyster, go wild!
Percolation Methods are those that the water only comes in contact with the water that is used for brewing during the time that it's flowing through the method. Usually results in a milder but more delicate brew.
Infusion Methods are those that the water is in constant contact with the hot water, thus extracting less nuanced flavors but stronger bodied ones.

Bionic Showdown: The Six Million Dollar Man and the Bionic Woman (1989) A film review by Timothy Voon Copyright 1997 Timothy Voon
The 1989 BIONIC SHOWDOWN should have been one of those tele-movies long forgotten in the whirlpool of ordinariness surrounding the 80's. If not for a then unknown, but now well known star known as Ms Sandra Bullock, this movie would not have come to my attention at all. In this particular episode of metallic hardware, Sandra is the latest instalment or should I say successor, of the Bionic Woman aka Jamie Summers (Lindsey Wagner). Back with old flame Steve Austin (Lee Majors), whose circuits are getting outdated as quickly as CPU's come in and out of vogue, they once again battle the forces of evil.
Moving away from the popular theme of Bionics vs Cyborgs, the plot has been redirected towards a scenario more common ground to the 80's - namely the cold war between the east and west. Playing on the hot prospect of tense relationships between the Soviet Union and the United States, the villains aim to antagonise all concerned in order to generate self-profit. Their wild card comes in the form of a new bionic man.
So where does Ms Bullock fit into the big scheme of things? Well, she's a young woman who was crippled during her childhood, and carries with her intelligence, wit, sensitivity and humour. These characteristics become evident in movies like SPEED and WHILE YOU WERE SLEEPING, are present a decade ago. Even in this early piece of acting, she is beginning to show the elements of vulnerability that make people love and want to protect her. This is a weapon more powerful than bionics if you ask me.
As for Jamie Summers and Steve Austin, surviving the eighties has become harder than just reliving the seventies. With good humour and humility, they graciously make room to the new generation of bionics that has emerged to replace them. Jamie gets to pull a door apart and uses her bionic ear only once. Steve gets to flex his bionic muscles, but gets badly beaten by the new bionic on the block. Sad to say they are a living testimony of the changing times and rapidly advancing technology.
However, the spotlight in this movie falls on Sandra. She is left with the difficult task of defeating the evil bionic. For some unknown reason she is technologically weaker than her male counterpart, and has to use her brains instead of her brawn to defeat the villain. All that starts well also ends well, but one gets the benign feeling that this movie was intended to spawn a new tele-series. But time has revealed that this was not to be and fortunately so, otherwise Sandra Bullock may not be the movie star we know today.

Coding is the language of the future, and every girl should learn it. As I've learned from watching girls grow and learn in our classrooms, coding is fun, collaborative and creative.

Object Controls are a lightweight attempt to make manipulating objects in three.js slightly easier. I'm open to suggestions, and would love to hear if / how you use it, so please hit me up on Twitter if you have any questions / concerns / comments / general hatred.
Controlling objects in three.js is already very easy, and you can see some great examples of how to do it yourself by looking at some three.js examples:
But if you want to not have to implement it yourself, these controls are a great place to start! To see what can be done with them, Check out some of the following projects:
There is also bunch more examples you can check out if you are more of a 'stare at the code' human being:
But lets talk about how to actually use the code!
First off include the script:
<script src="PATH/TO/ObjectControls.js"></script>
Do all the thing that you would normally do with threejs, like setting up the renderer, scene and camera. Once you have done all this you can initialize the controls:
objectControls = new ObjectControls( camera );
The 'camera' is passed into the ObjectControls , as the 'Eye' of the raycast. You could pass in a different 'eye' if you want, but it probably won't make too much sense...
Within your 'animate' loop, make sure that you update the objectcontrols, like so:
objectControls.update();
This is all you have to do to set up the Object Controls. But so far they don't do anything, so lets see how we can change that!
The object controls are used by adding meshes to them. All of the logic of what happens when the meshes are interacted with is added to the mesh, so it controls itself! Here's a basic example of how to add meshes to the object controls:
var mat = new THREE.MeshNormalMaterial();
var geo = new THREE.IcosahedronGeometry( 10 , 1 );
var mesh = new THREE.Mesh( geo , mat );
// This is what will be called when
// the mesh gets hovered over ( intersected
mesh.hoverOver = function(){
}
// This is what will get called when
// the mesh gets hovered out ( unintersected )
mesh.hoverOut = function(){
}
// This is what will be called if teh mesh
// is both hovered, and the mousedown / touch happens
mesh.select = function(){
}
// This is what will be called if the mesh
// is selected and than becomes 'deselected'
// AKA the mouse gets released
mesh.deselect = function(){
}
// This is what will be called
// every frame on the mesh while it is
// selected
mesh.update = function(){
}
In addition to controling a mesh as shown above, you can also control an Object3D with child meshes. Then events are triggered on the Object3D whenever any of its child meshes are intersected. To enable, set recursive:true in the params passed to the ObjectControls constructor, as shown in the HighlightGroup example.
As usual, although the code is stable, this is still a work in progress, so if you see any problems, please please please let me know! Also, if there is something you want to see implemented, have any other suggestions, or use the code for anything I'd love to see how you used it, so hit me up on Twitter
