STEAD SOCIETY
(Science, Technology, Engineering and Arts Development Society) is a new organization within students at Fourah Bay College
and Njala University that is taking an innovative approach to support minorities in STEAM fields and also promote Human
Capital Development in Sierra Leone. The mission of STEAD is in TWO bigger fold:
-
To foster interaction and collaboration within students that are passionate about STEAM
-
To use innovative and creative ideas to provoke thought discussions and engagement of issues
affecting students, minorities in STEAM and the country
We plan to achieve these goals by advocating for more practical knowledge
in the STEAM field and also train the young generation to identify and master
their profession for the benefit of the nation and promote human capital development in Sierra Leone. The above goals comprises of greater efforts from STEAD to foster communication within the STEAM community and the greater public, and in doing so, help to bring a voice to students and minorities facing challenges in the STEAM field and also to invest in human capital development.
OBJECTIVES FOR THIS STEAD LAB
- “STEAD” Recommend, Sensitize, train and educate students and youths that are passionate about STEAD to take part in providing educative and innovative solutions to solve pressing life challenges in their School, College, Community and their nation as a whole.
- ”STEAD” discourages any form of discrimination that will perpetrate among ethnics, region, disabilities, and political cause
- ”STEAD” we help the government in fulfilling their core goals. That is, quality education and human capital development by offering our service in terms of mentorship, tutorials and projects for school going children, university students and youth across the country in science, Technology and Innovation.

Digital Logic
Basic Introduction
We are in “Information age” since digital systems have such a prominent and growing role in modern society. They are involved in our business transactions, communications, transportation, medical treatment and entertainment. In industrial world they are heavily employed in design, manufacturing, distribution and sales.Analog System
Analog systems process analog signals (continuous time signals) which can take any value within a range, for example the output from a speaker or a microphone.Digital System
Digital systems process digital signals which can take only a limited number of values (discrete steps), usually just two values are used: the positive supply voltage (+Vs) and zero volts (0V). Digital systems contain devices such as logic gates, flip-flops, shift registers and counters. The general purpose digital computer is a best known example of digital system.Generic Digital computer structure
Working principle of generic digital computer:
Memory stores programs as well as input, output and intermediate data. The datapath performs arithmetic and other data-processing operations as specified by the program. The control unit supervises the flow of information between the various units. A datapath, when combined with the control unit, forms a component referred to as a central processing unit, or CPU. The program and data prepared by the user are transferred into memory by means of an input device such as a keyboard. An output device, such as a CRT (cathode-ray tube) monitor, displays the results of the computations and presents them to the user.Advantages of digital system:
- Have made possible many scientific, industrial, and commercial advances that would have been unattainable otherwise.- Less expensive
- More reliable
- Easy to manipulate
- Flexibility and Compatibility
- Information storage can be easier in digital computer systems than in analog ones.
- New features can often be added to a digital system more easily too.
Disadvantages of digital system:
- Use more energy than analog circuits to accomplish the same tasks, thus producing more heat as well.- Digital circuits are often fragile, in that if a single piece of digital data is lost or misinterpreted, the meaning of large blocks of related data can completely change.
- Digital computer manipulates discrete elements of information by means of a binary code.
- Quantization error during analog signal sampling.
Information Representation
Signals
- Information variables represented by physical quantities. - For digital systems, the variables take on discrete values. - Two level or binary values are the most prevalent values in digital systems. - Binary values are represented abstractly by: i) digits 0 and 1 ii) words (symbols) False (F) and True (T) iii) words (symbols) Low (L) and High (H) iv) and words On and Off. - Binary values are represented by values or ranges of values of physical quantities<
What are other physical quantities representing 0 and 1?
CPU: Voltage
Disk: Magnetic Field Direction
CD: Surface Pits/Light
Dynamic RAM: Electrical Charge
Number Systems
Here we discuss positional number systems with Positive radix (or base) r. A number with radix r is represented by a string of digits as below i.e. wherever you guys see numbers of whatever bases, all numbers can be written in general as:Most Significant Digit (MSD) Least Significant Digit (LSD)
Integer portion (n digits) Fractional portion (m digits)
in which 0 ≤ Ai < r (since each being a symbol for particular base system viz. for r = 10 (decimal number system) Ai will be one of 0,1,2,…,8,9). Subscript i gives the position of the coefficient and, hence, the weight ri by which the coefficient must be multiplied.
HEY! Confused? Don’t worry! I will describe specific number systems (r=2, 8, 10 and 16) used in digital computers later one by one, then the concept will be quite clear.
In general, a number in base r contains r digits, 0, l, 2... r- 1, and is expressed as a power series in r with the general form: (Number)r = An-1 rn-1 + An-2 rn-2 + … + A1 r1 + A0 r0 + A-1 r-1 + A-2 r-2 + … + A-m+1 r-m+1 + A-m r-m
Decimal Number System (Base-10 system)
Radix (r) = 10 Symbols = 0 through r-1 = 0 through 10-1 = {0, 1, 2... 8, 9}I am starting from base-10 system since it is used vastly in everyday arithmetic besides computers to represent numbers by strings of digits or symbols defined above, possibly with a decimal point. Depending on its position in the string, each digit has an associated value of an integer raised to the power of 10.
Example:
decimal number 724.5 is interpreted to represent 7 hundreds plus 2 tens plus 4 units plus 5 tenths.
724.5 = 7 X 102 + 2 X 101 + 4 X 100 +5 X 10-1
Binary Number System (Base-2 system)
Radix (r) = 2 Symbols = 0 through r-1 = 0 through 2-1 = {0, 1}A binary numbers are expressed with a string of 1'sand 0's and, possibly, a binary point within it. The decimal equivalent of a binary number can be found by expanding the number into a power series with a base of 2.
Example:
(11010.01)2 can be interpreted using power series as:
(11010.01)2 = 1 X 24 + 1 X 23 + 0 X 22 + 1 X 21 + 0 X 20 +0 X 2-1 + 1 X 2-2 = (26.25)10

What does profile-guided optimization mean?
Some languages have a JIT (Just In Time) compiler available at runtime, that can optimize the executed code depending on current execution patterns. This is, in large part, the cause of the performance of Lua and the JVM. They can start a bit slow, but by accumulating information on actual running code, they make it faster and faster for the current load. PfLua is a great example: the firewall rules are optimized again and again, until the current network traffic is handled as quickly as possible.
When you use other languages, such as C, you usually cannot optimize the application once it is compiled. Except when you use an optimization technique known as Profile-Guided Optimization. From Wikipedia :
Profile-guided optimization (PGO, sometimes pronounced as pogo), also known as profile-directed feedback (PDF), is a compiler optimization technique in computer programming that uses profiling to improve program runtime performance.
It relies on profiling the compiled application, while it runs with the expected, real world load (web traffic, calculations, etc), and feed this profiling information to the compiler. On the next build, the compiler will have more information on which parts of the program are less used, which branches are taken more often, the expected values in a range, etc. Instead of guessing how the program would behave to choose optimizations, the compiler has true information, and can optimize more precisely. There's one issue with the process: you need two compilations and a profiling run to generate the final executable. But it gets easier when you automate it, as we can see in the Firefox build process.
PGO in LLVM
While it has been available in other systems for a long time (Visual Studio 2005, the Intel compiler ICC for Itanium), it appeared recently in LLVM. It has since then been applied successfully to XCode (Objective C, Swift) and LDC, the D compiler.
LLVM has a great feature: it uses an Intermediate Representation code (IR), which is a kind of high level assembly language. It applies its optimizations and machine code generation to that representation. If you make a compiler for a new language, targeting the LLVM IR will give you these features (nearly) for free.
In practice, compiler frontends choose which features they use, so you may not access everything LLVM has to offer. In particular, the Rust compiler, as of now (April 2016), provides a llvm-args option, but that option filters what you can send to LLVM, so we cannot use PGO here.
PGO in Rust
Still, with rustc, you can generate directly the IR, or its binary encoding, named bitcode:
rustc --emit llvm-bc main.rs
# or, with cargo:
cargo rustc -- --emit llvm-bc
The approach I tried here is to take that bitcode, and manually apply LLVM's transformations until I get a compiled executable. This is not really usable for now, especially because I chose an example with very few dependencies. With more dependencies, the compilation and linking will get more complex and unmanageable manually.
LLVM comes with a few commands that you can use to build code manually. The first one is opt, and it applies optimizations and instrumentation on the bitcode file (here, the file target/release/pgo.bc):
opt-3.8 -O2 -pgo-instr-gen -instrprof target/release/pgo.bc -o pgo.bc
The new bitcode file contains code to profile the end application (mainly by counting how often we use each code path). We can now convert that bitcode file to an object file, and link it using clang:
llc-3.8 -O2 -filetype=obj pgo.bc
clang-3.8 -O2 -flto -fprofile-instr-generate pgo.o -L/usr/local/lib/rustlib/x86_64-apple-darwin/lib -lstd-ca1c970e -o pgo
Note: I built my own rustc from source, so your libstd file may not have the same hash. Since Rust (as of April 2016) uses LLVM 3.7, we can use LLVM 3.8's PGO features, since the bitcode format is apparently backward compatible. I use OS X, and Homebrew's LLVM 3.8 has compilation issues, so I needed to build the compiler runtime from source. It's a proof of concept, not production code ;)
We will now run the program we just built, preferably with production data and traffic. It will automatically generate a default.profraw file, containing the profiling information. This file must be transformed to a format that opt will understand with llvm-profdata:
llvm-profdata-3.8 merge -output=pgo.profdata default.profraw
This .profdata file will now be used in the compilation steps:
opt-3.8 -O2 -pgo-instr-use -pgo-test-profile-file=pgo.profdata target/release/pgo.bc -o pgo-opt.bc
llc-3.8 -O2 -filetype=obj pgo-opt.bc
clang-3.8 -O2 -flto -fprofile-instr-use=pgo.profdata pgo-opt.o -L/usr/local/lib/rustlib/x86_64-apple-darwin/lib -lstd-ca1c970e -o pgo-opt
We now have an executable compiled using profiling information. Is it fast?
The benchmarks
The program I tested is a n-body simulation. It was a great test target since libstd is the only dependency, and the load factor depends on a number given as command line argument. Here is a test with time (I know it's not the most precise benchmarking tool, but for a tenth of second precision, it works alright):
$ time ./target/release/pgo<PHONE_NUMBER>
-0.169075164
-0.169051540real 1m22.528s
user 1m22.214s
sys 0m0.173s$ time ./pgo-opt<PHONE_NUMBER>
-0.169075164
-0.169051540real 1m9.810s
user 1m9.687s
sys 0m0.070s
As it turns out, we gain nearly 15% in running time on this program. Other examples could have less impact, but this is encouraging! So, what happened inside our program?
The generated code
I provide assembly dumps of the normal program, generated with cargo --release, and the one optimized with PGO. Mostly, the code has been reordered, probably to fit better in cache lines. You can also consult PDF files with call graphs: normal, PGO optimized.
The whole code for this article is available here if you want to reproduce the results or tinker with optimizations yourself.
This is a proof of concept, demonstrating that profile guided optimization could work in Rust. It is probably worthy of integration into rustc, but there's a lot of work before it could be usable. Still, there's a github issue where you can weigh in, if you would like this optimization in your applications.

Class: Aws::DynamoDBStreams::Client
| Inherits: |
Seahorse::Client::Base
|
| Defined in: |
(unknown) |
Overview
An API client for Amazon DynamoDB Streams. To construct a client, you need to configure a :region
and :credentials
.
dynamodbstreams = Aws::DynamoDBStreams::Client.new(
region: region_name,
credentials: credentials,
# ...
)
See #initialize
for a full list of supported configuration options.
Region
You can configure a default region in the following locations:
ENV['AWS_REGION']
Aws.config[:region]
Go here for a list of supported regions.
Credentials
Default credentials are loaded automatically from the following locations:
ENV['AWS_ACCESS_KEY_ID']
andENV['AWS_SECRET_ACCESS_KEY']
Aws.config[:credentials]
- The shared credentials ini file at
~/.aws/credentials
(more information) - From an instance profile when running on EC2
You can also construct a credentials object from one of the following classes:
Alternatively, you configure credentials with :access_key_id
and
:secret_access_key
:
# load credentials from disk
creds = YAML.load(File.read('/path/to/secrets'))
Aws::DynamoDBStreams::Client.new(
access_key_id: creds['access_key_id'],
secret_access_key: creds['secret_access_key']
)
Always load your credentials from outside your application. Avoid configuring credentials statically and never commit them to source control.

Constructor Details
.new(options = {}) ⇒ Aws::DynamoDBStreams::Client
Constructs an API client.
Instance Method Details
#describe_stream(options = {}) ⇒ Types::DescribeStreamOutput
Returns information about a stream, including the current status of the stream, its Amazon Resource Name (ARN), the composition of its shards, and its corresponding DynamoDB table.
You can call DescribeStream at a maximum rate of 10 times per second.
Each shard in the stream has a SequenceNumberRange
associated with it. If the SequenceNumberRange
has a StartingSequenceNumber
but no EndingSequenceNumber
, then the shard is still open (able to receive more stream records). If both StartingSequenceNumber
and EndingSequenceNumber
are present, then that shard is closed and can no longer receive more data.
#get_records(options = {}) ⇒ Types::GetRecordsOutput
Retrieves the stream records from a given shard.
Specify a shard iterator using the ShardIterator
parameter. The shard iterator specifies the position in the shard from which you want to start reading stream records sequentially. If there are no stream records available in the portion of the shard that the iterator points to, GetRecords
returns an empty list. Note that it might take multiple calls to get to a portion of the shard that contains stream records.
GetRecords
can retrieve a maximum of 1 MB of data or 1000 stream records, whichever comes first.
#get_shard_iterator(options = {}) ⇒ Types::GetShardIteratorOutput
Returns a shard iterator. A shard iterator provides information about how to retrieve the stream records from within a shard. Use the shard iterator in a subsequent GetRecords
request to read the stream records from the shard.
A shard iterator expires 15 minutes after it is returned to the requester.
#list_streams(options = {}) ⇒ Types::ListStreamsOutput
Returns an array of stream ARNs associated with the current account and endpoint. If the TableName
parameter is present, then ListStreams will return only the streams ARNs for that table.
You can call ListStreams at a maximum rate of 5 times per second.
#wait_until(waiter_name, params = {}) {|waiter| ... } ⇒ Boolean
Waiters polls an API operation until a resource enters a desired state.
Basic Usage
Waiters will poll until they are succesful, they fail by entering a terminal state, or until a maximum number of attempts are made.
# polls in a loop, sleeping between attempts client.waiter_until(waiter_name, params)
Configuration
You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. You configure waiters by passing a block to #wait_until:
# poll for ~25 seconds
client.wait_until(...) do |w|
w.max_attempts = 5
w.delay = 5
end
Callbacks
You can be notified before each polling attempt and before each
delay. If you throw :success
or :failure
from these callbacks,
it will terminate the waiter.
started_at = Time.now
client.wait_until(...) do |w|
# disable max attempts
w.max_attempts = nil
# poll for 1 hour, instead of a number of attempts
w.before_wait do |attempts, response|
throw :failure if Time.now - started_at > 3600
end
end
Handling Errors
When a waiter is successful, it returns true
. When a waiter
fails, it raises an error. All errors raised extend from
Waiters::Errors::WaiterFailed.
begin client.wait_until(...) rescue Aws::Waiters::Errors::WaiterFailed # resource did not enter the desired state in time end
#waiter_names ⇒ Array<Symbol>
Returns the list of supported waiters. The following table lists the supported waiters and the client method they call:
| Waiter Name | Client Method | Default Delay: | Default Max Attempts: |
|---|

Oil dips in Asia on waning trade optimism
by Omkar Godbole- Oil is flashing red, possibly due to waning US-China trade optimism.
- Risk has come under pressure in Asia with Nikkei falling 1%.
Oil prices on both sides of the Atlantic are flashing red amid warning US-China trade optimism and the resulting risk-off tone in the global markets.
At press time, a barrel of Brent is changing hands at $62.20, representing a 0.35% drop on the day. WTI is also trading in the red at $56.90 per barrel.
The losses could be associated with reports stating that the phase one" U.S.-China trade deal could slip into next year.
Some observers are worried that trade talks may fall apart due to the renewed political tensions between the US and China. The world's second-largest economy on Wednesday condemned a US Senate bill aimed at protecting human rights in Hong Kong. Meanwhile, US President Donald Trump said he is inclined to raise tariffs on Chinese imports if a trade deal is not reached.
As a result, the risk has come under pressure in Asia. The futures on the S&P 500 are currently reporting a 0.10% drop. The index fell by 0.38% on Wednesday. Stocks in Asia are also losing ground with Japan's Nikkei shedding 1.15% and the Shanghai Composite reporting a 0.20% drop.
China's Vice Premier Liu He was out on the wires a few minutes before press time stating that he is cautiously optimistic about reaching a trade deal. USD/JPY has bounced up more than 20 pips on Liu He's comments, however, equities continue to operate on slippery grounds.
Oil, therefore, is struggling to extend Wednesday's 3% gain. The black gold picked up a strong bid during the US trading hours on Wednesday after official data showed crude inventories in the United States increased by 1.4 million barrels for the week ending Nov. 15, less than the 1.6 million barrels analysts surveyed by S&P Global Platts.

typekind =
[ `Lower | `Upper ]
Distinguish between lower and upper bounds
val empty : int -> int -> t
Returns an empty approximation that does not contain any non-trivial information. That means, that every upper bound is infinite and every lower bound is minus infinite. The first parameter should be the count of transitions in the program. The second parameter should be the count of program variables.
val create : Program.t -> t
val time : t -> TransitionApproximation.t
val size : t -> SizeApproximation.t
val cost : t -> TransitionApproximation.t
val to_string : ?html:bool -> Program.t -> t -> string
val equivalent : t -> t -> bool
Timebound related methods
val timebound : t -> ProgramTypes.Transition.t -> Bound.t
Returns a timebound for the transition.
val timebound_id : t -> int -> Bound.t
Returns a timebound for the transition id.
val program_timebound : t -> Program.t -> Bound.t
Returns a timebound for the program.
val add_timebound : Bound.t -> ProgramTypes.Transition.t -> t -> t
Adds the information that the specified bound is a valid timebound for the given transition. The resulting approximation is guaranteed to be at least as good as the old approximation.
val all_times_bounded : t -> ProgramTypes.Transition.t list -> bool
val is_time_bounded : t -> ProgramTypes.Transition.t -> bool
Costbound related methods
val costbound : t -> ProgramTypes.Transition.t -> Bound.t
Returns a costbound for the transition.
val program_costbound : t -> Program.t -> Bound.t
Returns a costbound for the program.
val add_costbound : Bound.t -> ProgramTypes.Transition.t -> t -> t
Sizebound related methods
val sizebound : kind ->
t -> ProgramTypes.Transition.t -> Var.t -> Bound.t
Returns a sizebound of the specified kind for the var of the transition. A sizebound is expressed in relation to the input variable values of the program.
val add_sizebound : kind ->
Bound.t ->
ProgramTypes.Transition.t -> Var.t -> t -> t
Adds the information that the specified bound is a valid sizebound for the given variable of the transition. The resulting approximation is guaranteed to be at least as good as the old approximation.

Level up your programming skills. There’s a gap when you’re past the basics but real-world problems leave you swamped by details and wandering down rabbit holes. Exercism aims to fill that gap with lots of small, self-contained practice problems with just enough complexity to stretch your mind around new concepts.

Exceptions best practices in Haskell
I consider the safe-exceptions library uncontroversial, simply addressing the reality of exceptions in GHC today. This blog post is the opinionated part: how I recommend you use exceptions in Haskell, and how to structure your code around them.

Use MySQL safely in Yesod applications
With the latest version of the mysql library, we now have the machinery needed to use it properly in a concurrent setting. In the past, any multi-threaded use was a little risky, although in practice it seems to have been satisfactory for applications which were not too demanding.
-
Designing APIs for extensibility
Design your APIs from the outset to be extensible. There are common techniques employed in the Haskell world to make APIs that are resilient to changing feature-sets, and by employing them early on in your design process, you can hopefully avoid the painful choices between a better API and happy users.

Flame graphs for GHC time profiles with ghc-prof-flamegraph
Visualizing profiling data is a common problem, and one neat solution is to use flame graphs to get a high-level view of where time is spent, and why it is spent there. That’s why we wrote ghc-prof-flamegraph, a new utility useful for turning textual .prof reports into a pretty picture.

If you want to make anyone on the core Elm team roll their eyes, just pick a feature that Haskell has and say, “Elm should have it too.” Typeclasses is the most common way to play the game, but you’ll get extra hipster points if you say higher-kinded types.

14.4. Assignment OperatorsWe covered the assignment of one object of class type to another object of its type in Section 13.2 (p. 482). The class assignment operator takes a parameter that is the class type. Usually the parameter is a const reference to the class type. However, the parameter could be the class type or a nonconst reference to the class type. This operator will be synthesized by the compiler if we do not define it ourselves. The class assignment operator must be a member of the class so the compiler can know whether it needs to synthesize one. Additional assignment operators that differ by the type of the right-hand operand can be defined for a class type. For example, the library string class defines three assignment operators: In addition to the class assignment operator, which takes a const string& as its right-hand operand, the string class defines versions of assignment that take a C-style character string or a char as the right-hand operand. These might be used as follows: string car ("Volks"); car = "Studebaker"; // string = const char* string model; model = 'T'; // string = char To support these operations, the string class contains members that look like // illustration of assignment operators for class string class string { public: string& operator=(const string &); // s1 = s2; string& operator=(const char *); // s1 = "str"; string& operator=(char); // s1 = 'c'; // .... };
Assignment Should Return a Reference to *thisThe string assignment operators return a reference to string, which is consistent with assignment for the built-in types. Moreover, because assignment returns a reference there is no need to create and destroy a temporary copy of the result. The return value is usually a reference to the left-hand operand. For example, here is the definition of the Sales_item compound-assignment operator:
// assumes that both objects refer to the same isbn
Sales_item& Sales_item::operator+=(const Sales_item& rhs)
{
units_sold += rhs.units_sold;
revenue += rhs.revenue;
return *this;
}

Frameworks and Responsive Design
Grid-Based Design
HTML starts off arranging itself line by line, it's simple with just html to arrange elements vertically
in the way you'd like. Grid-based design involves splitting the webpage into columns and rows, this allows
content to sit side by side.
This can be done in a simple way by predefining a row class and column classes set at useful widths, each
row class uses flex box to fit the columns nicely side by side and a set of columns is chosen such that together they
take up the exact full width of the row-container they sit in. Any group of elements can be made to fit into the grid
by adding one of the column classes to it's HTML tag
Responsive Design
A webpage designed for a computer screen might not be that friendly on a phone screen, and vice versa. Responsive design is the practice of making webpages that adjust to the specific screen and device they are being viewed on so that the user experience is consistent/smooth across all devices.

Semantic Structure of HTML
While translating a design into HTML a first step is to split the page into rectangular portions, in a grid layout or some other format. The next is to choose which elements are of the same type, which ones are the most important etc. and set appropriate HTML tags. This allows for easy management, easy to read code and simple CSS access. This choice of types of HTML tag is the semantic structure.
Responsiveness without Scripting
I'm finding it interesting and user friendly that so much interactiveness and responsiveness is available with just HTML and CSS. I had expected the task of querying the device size and view window size to be part of the javascript.

Getting Started
Add gulp
$ npm install -g gulp
then, clone or fork this repository:
$ git clone -b master --single-branch https://github.com/nanopx/frill.git MyNewApp
$ cd MyNewApp && npm install
If you have your own repo...
Rename remote from origin
to upstream
$ git remote rename origin upstream
Set origin
to your repo
$ git remote add origin YOUR_REPO.git
Fetch updates from your repo
$ git fetch origin
NOTE: If any conflicts occur, fix them using your editor
Set master
branch's remote to origin/master
$ git branch master -u origin/master
Finally, push frill into your repo
$ git push
If your cloning from your existing frill repo, you'll need to add upstream
$ git remote add upstream https://github.com/nanopx/frill.git
Building your app
$ npm run build
or
$ gulp build
Run app and watch for changes
$ npm run watch
or
$ gulp
Run your app as a daemon
Start app
$ npm start
Stop app
$ npm stop
Restart app
$ npm restart
See forever for more information.
Deploying your app
Install Shipit
$ npm install -g shipit
Configure deployments
inside ./config/default.js
to your environment, then
For production
$ shipit production deploy
For staging
$ shipit staging deploy
shipit (environment) pwd
, shipit (environment) start
, shipit (environment) stop
, shipit (environment) restart
is configured by default.
See Shipit and shipit-deploy for more information.
Testing your app
$ npm test
exports
NODE_ENV=test
automatically
or
$ NODE_ENV=test gulp test
IMPORTANT: You should always use
test
for yourNODE_ENV
environment variable to make sure that your production/development database will not be affected by tests
Updating frill
Fetch changes from frill
$ git checkout master
$ git fetch upstream
$ git merge upstream/master

About CircleCI and Code Climate
NOTE: If your're planning to use Travis CI or anything else, you might want to skip this part.
If you're using CircleCI, then you must check the configuration inside ./circle.yml
.
By default, it uses npm run test-cov
for testing, which executes tests and measures the coverage of your code using Istanbul, and sends statistics to Code Climate by running npm run code-climate
after the test.
If you don't want to use Code Climate, simply remove the following configurations inside ./circle.yml
.
test:
override:
- npm run test-cov
post:
- npm run code-climate
If you have decided to use both CircleCI and Code Climate, don't forget to set the CODECLIMATE_REPO_TOKEN
environment variable inside the CircleCI's repo settings.

I have been a regular coffee drinker since the age of 12 (I'm now almost 22). The habit started innocuously; I would have a cup every morning before going off to middle school. Within a year, I was drinking another cup in the afternoon. By high school, I was drinking two or three cups a day. I would quit intermittently and feel pretty good (much better than when I was using caffeine regularly). For various reasons, though, I would keep going back to it.
In the first two years of college I bounced between coffee and tea drinking; I would normally drink four cups of coffee and a coke or up to ten cups of tea every day. For even more energy during finals (and sometimes during other stressful times) I would combine this with Vivarin or with diet pills containing ephedrine.
Within the past year I've experienced an incredible amount of anxiety, possibly as a consequence of this heavy use. To alleviate this, I've often consumed too much alcohol. Along with the alcohol, I would use tobacco products (to which I quickly became addicted). During periods of great stress, my heart would pound and I would feel a stabbing pain at the base of my neck. Needless to say, I was poisoning myself. I realized that to stop one threat to my health I would have to stop them all.
I've recently quit everything all together and, to be honest, can't guarantee that this attempt will be successful. I quit coffee 'cold turkey' three days ago; now I'm waiting for the proverbial light at the end of the tunnel. A testament to the level of my addiction is that I am now incredibly lethargic, with pounding headaches and bouts of nausea. Waves of depression sweep over me. I let myself have a candy bar or a coke, and that helps a little. Subtle signs (no anxiety, a general feeling of well-being in between the withdrawal symptoms) indicate that things will improve and that I've made the right choice.

| lesson 38 The first calendar |
| Future historians will be in a unique position when they come to record the history of our own times. |
| They will hardly know which facts to select from the great mass of evidence that steadily accumulates. |
| What is more, they will not have to rely solely on the written word. |
| Films, videos, CDs and CD-ROMS are just some of the bewildering amount of information they will have. |
| They will be able, as it were, to see and hear us in action. |
| But the historian attempting to reconstruct the distant past is always faced with a difficult task. |
| He has to deduce what he can from the few scanty clues available. |
| Even seemingly insignificant remains can shed interesting light on the history of early man. |
| Up to now, historians have assumed that calendars came into being with the advent of agriculture, |
| for then man was faced with a real need to understand something about the seasons. |
| Recent scientific evidence seems to indicate that this assumption is incorrect. |
| Historians have long been puzzled by dots, lines and symbols which have been engraved on walls, bones, and the ivory tusks of mammoths. |
| The nomads who made these markings lived by hunting and fishing during the last Ice Age which began about 35, 000 B. C. and ended about 10, 000 B. C. |
| By correlating markings made in various parts of the world, historians have been able to read this difficult code. |
| They have found that it is connected with the passage of days and the phases of the moon. |
| It is, in fact, a primitive type of calendar. |
| It has long been known that the hunting scenes depicted on walls were not simply a form of artistic expression. |
| They had a definite meaning, for they were as near as early man could get to writing. |
| It is possible that there is a definite relation between these paintings and the markings that sometimes accompany them. |
| It seems that man was making a real effort to understand the seasons 20, 000 years earlier than has been supposed. |

The char type differs from the string(1) type in the following way: char always represents exactly one character, while string(1) can represent either the null string or a string containing one character. The char type is similar to the char(1) type in that both contain at most one character.
The char type is an index type and can be used, for example, as subscripts, for ranges and case labels. For example, this declaration
| var charCounts : array char of int |
creates an array whose subscripts are characters.
The char type is a scalar type, which implies that its parameters are passed by value, instead of by reference (which is the case for char(n) and string).
Values of the char type can be assigned and they can be compared for both equality and ordering. Explicit char constants are written as a character surrounded by single quotes, for example, 'A'. For details, including how to write control characters, see explicitCharConstant.
Characters can be read and written by get and put statements.
There are 256 char values, corresponding to the distinct patterns in an 8-bit byte. This allows the patterns eos (internal value 0) and uninitchar (internal value 128) to be char values (these patterns are not allowed in the string type; see the string type). All 256 patterns are used, so there is no pattern left to be the "uninitialized value". Uninitialized checking is not done for the char type.
The ord and chr functions convert between the char values and their corresponding numeric representation in a byte. See ord and chr.
In general, you can freely intermix the values of the types char, char(n) and string. This means that catenation (+), comparisons, length and substrings can be applied to any of these types. See char(n) for details about conversions between char, char(n) and string.


func AddContentTypeJson(w *http.ResponseWriter)
AddContentTypeJson adds the content type header to responses.
func ComputeNewValuesRequest() messages.NewValuesRequest
TODO: change docs, from today 26/12/19 ComputeNewValuesRequest will return and empty "missing" field, i.e. it will only ask for new (higher) values TODO: no need to perform any changes when receiving (i.e. inside ComputeNewValuesResponse) since an empty "missing" does not raise any problem ComputeNewValuesRequest computes the list of turn ids needed by the askForNewValues function. One component of the request is the last turn id learnt (last when sorted, i.e. the highest). The other component is a list of 'missing' turn ids. The list is computed starting from 1 and going to the last id. If an element is not found in neither one of the two tables (proposal, learnt) then it's added to the list. e.g.
Turn IDs in 'proposal' table --> P = [1, 2, 5, 6, 10] Turn IDs in 'learnt' table --> P = [1, 2, 8] The message we send will have lastID = 7, missing = [3, 4, 7]
5, 6 are not included since they are dangling proposals and will be handled by askForDanglingProposals. any value higher than 8 (9, 10) is currently ignored, but if any node has info about any proposal with turnID > 8 it will let us know since we told them what our highest turn id was.
func ComputeNewValuesResponse(newValuesRequest messages.NewValuesRequest) messages.NewValuesResponse
ComputeNewValuesResponse returns a NewValuesResponse message containing a amp with values to be learned by the requester. This function is only triggered when a node sends a NewValuesRequest.
func EnableCors(w *http.ResponseWriter)
EnableCors allows requests from anywhere.
func GetLearntValue(turnID int) messages.GenericMessage
GetLearntValue returns a message with the 'learnt' field containing the value (@v) of the proposal with turn ID = @turnID. If the requested turn ID does not exist, the 'learnt' field will contain an empty string.
func ReceiveAccept(acceptRequest messages.GenericMessage) messages.GenericMessage
ReceiveAccept implements the acceptor's behaviour when receiving an accept request. This function compares the stored proposal (@oldP) against the proposal received as input (@newP) and returns an "accept" when @newP is strictly higher or equal to @oldP, otherwise it returns a "decline" message. In both cases @oldP (which might be null) is appended to the final response message. In some cases the acceptor might notice that a value has already been learnt for the requested proposal, in that case this information will also be appended to the response message. This function is very similar to ReceivePrepare, the distinction is made just to avoid multiple small if-else clauses.
func ReceiveLearn(learnRequest messages.GenericMessage) messages.GenericMessage
ReceiveLearn implements the learner's behaviour when receiving a learn request. If the proposed value has not been learnt yet it gets learnt immediately and learn requests with that value are sent to each known node. If the proposed value has already been learnt then no action is performed. If we get a proposal to learn a value which is different from the value we already have for that turn id
func ReceivePrepare(prepareRequest messages.GenericMessage) messages.GenericMessage
ReceivePrepare implements the acceptor's behaviour when receiving a prepare request. This function compares the stored proposal (@oldP) against the proposal received as input (@newP) and returns a "promise" when @newP is STRICTLY higher than @oldP, otherwise it returns a "retry" message. In both cases @oldP (which might be null) is appended to the final response message. In some cases the acceptor might notice that a value has already been learnt for the requested proposal, in that case this information will also be appended to the response message. This function is very similar to ReceiveAccept, the distinction is made just to avoid multiple small if-else clauses.
func ResponseHasLearntValue(responseMessage messages.GenericMessage) bool
ResponseHasLearntValue checks whether the response contains a non empty string in the 'learnt' field. If that is true it means that the responding node has already learnt a value for the current turn id.
func SendAccept(turnID int, seq int, v string) (messageToUser string)
SendAccept sends an accept request to all the acceptors in the network, the values of the accept request are agreed upon during the prepare request, if @v is empty a default value will be assigned to it. SendAccept should only be called when it is right to do so, i.e. when the prepare request was "promised" by a majority of nodes. Calling this function outside the normal flow of the algorithm does not guarantee the correctness of the system. Note that when the node is working in AUTOMATIC mode, this function is called automatically after reaching the quorum for the prepare request.
func SendLearn(turnID int, v string) string
SendLearn sends an learn request to all the acceptors in the network, the value of the learn request are the values agreed upon during the accept request. Note that when the node is working in AUTOMATIC mode, this function is called automatically after reaching the quorum for the accept request.
func SendPrepare(turnID int, seq int, v string) (messageToUser string)
SendPrepare sends a prepare request to all the acceptors in the network, the values of the prepare request are to be provided by the user (except @v which can remain empty).
func SendSeek()
SendSeek calls the function askForDanglingProposals and askForNewValues. Both of those aim to achieve eventual consistency.
func ToJson(i interface{}) string
ToJson is used to marshal interfaces into a valid json string.
| Name | Synopsis |

Welcome to my work term report created for Freshbooks! Here you'll learn about my duties at Freshbooks as a Software Developer as well as learn more about the product and the work I completed this term. Freshbooks is a software as a service company which helps empower small business owners who don't know accounting, manage their expenses, request invoices and much more. First and foremost, the culture and talent at Freshbooks is among the best, I had a great time working there and I truly felt like a full-time employee. The office itself was also amazing, a dog friendly office never failed to put a smile on my face and I think I gained an equal amount of skill at pingpong as I did coding!
At the job, I had many goals which included: - Gain knowledge of a flask and python back-end development - Learn a front-end javascript framework, Ember in this case - Develop my skills in machine learning and data science These were goals as I entered the job, and many I was able to fulfill, as well as many new ones I created a long the way.
At Freshbooks, I worked on team Compass and eventually team Encompass , which has a mandate to help guide users through all stages of the web app and then work on customer acquisition. Lots of my work was focused in either Flask (Python) and EmberJS (Javascript) work. I worked on features using customer data on how to better the product, which included tasks such as: increasing mobile app engagement, SMS integration and iOS push notifications. My everyday consisted of getting into office, attending meetings and standup then getting to code. For every task I did, tests were a large portion of the development, so I was able to learn about various testing suites such as Capybara and the Cucumber tool. As well, I received valuable feedback on all my pull requests from experienced software developers at the company which helped accelerate my learning and progression as a softwarew developer.
In conclusion I had a great time working at Freshbooks and the employees and my team especially made it a great experience. The company truly valued each employee and motivated development and learning, and was a great four months towards my career growth.
