The thought of the race which was to take place within a few days and in which both the Black Growler and the Varmint II were to be contestants was in the mind of every one. In spite of the unwillingness of Sam to express his opinion as to the outcome, Fred insisted repeatedly upon asking what he thought. Again and again Sam evaded a direct reply as in one form or another he explained that all he did know was that the Black Growler would win if she could run more swiftly than the Varmint II.
As to the possibility of developing the required speed he was non-committal.
Conversation did not lag on the voyage down the river. The presence of Mr. Button as well as the fact that Fred apparently was somewhat reserved and uncommunicative concerning his recent experiences in Cape Vincent, caused the Go Ahead boys to neglect the topic of conversation which just then was uppermost in their thoughts. Time did not drag, however, and it was a merry party on the motor-boat which attracted the attention of many of the parties they met. In the most informal manner salutes were given and whistles were tooted whenever boats large or small passed.
In spite of Miss Susie’s apparent carelessness she had provided a most excellent luncheon, to which ample justice had been done by all on board, including Mr. Button.
It was late in the afternoon, however, when the two girls were left at their cottage and the Black Growler sped forward toward Chestnut Island.
As soon as a landing was made Mr. Button at once started for the cottage.
Left to themselves Fred’s three friends quickly turned upon him and eagerly began to question him concerning his experiences at Cape Vincent.
“Where’s your man that wanted the bond?” demanded George.
“Did you get the bond?” asked Grant.
“Did you find out who that fellow is?” inquired John.
“Hold on, fellows,” laughed Fred. “I’ll take you one at a time, but I don’t want you all together. Now then speak up, one of you. What is it you want to know?”
“Did you find out who that man is?” asked John.
“I fancy you’re referring to the gentleman who requested us to deliver to him that five thousand dollar bond?” answered Fred.
“You catch my meaning exactly,” answered John solemnly.
“Well, then, let me say that he is just as big a mystery to me as he is to you.”
“Did he get the bond?” demanded Grant.
“I don’t know.”
“Weren’t you with him?”
“I was, but not all the time.”
“Did he go to the bank?”
“He certainly did.”
“Weren’t you there, too? Couldn’t you see whether they gave him the bond or not?”
“Not being able to see through a foot wall, and a door still stronger, I am unable to give you the information you so courteously request.”
“What do you mean? Can’t you speak in plain English?”
“I’ll do my best,” laughed Fred, who so often had been the object of attention from his friends that now he was rejoiced that in a measure at least the tables were turned. “Well, we were at the bank,” he continued. “My grandfather told me to stay outside while he went into Mr. Reese’s office. They were in there about five minutes and then Mr. Reese came out and asked me to tell our canal-boat friend that his presence was desired in the office, so I went outside the bank and found the man they were looking for, gave him the message and then I went back.”
“Didn’t they want you in the office too?” inquired John.
“I didn’t receive any strong urging to enter,” laughed Fred, “so I decided it was better for me to stay outside.”
“How long were they in there?” inquired Grant.
“I suppose it was about half an hour, but it seemed a good deal longer.”
“Who came out first?”
“The canal-man.”
“Was he alone?”
“Yes.”
“How long before any one else came out?”
“Five minutes anyway, perhaps ten.”
“What did your friend do?”
“He went out of the bank and that’s the last I saw of him.”
“You don’t know then whether he went to the hotel or the station, or came down the river.”
“I have told you just what I know and all I know. I can’t do any more.”
“So we’re just as wise as we were when we began,” laughed George. “We don’t know what has become of our bond nor where the man that wanted it went. We don’t even know whether or not it is in the bank yet.”
“Don’t begin on the list of things you don’t know, George,” said Fred soberly. “It’ll take too much time.”
“It’s a good thing to know that you don’t know.  Now, I know some things and among the things I know, I know that I don’t know some things that I think I know.”
The Go Ahead boys laughed as they all started toward the cottage to prepare for dinner.
The following morning Fred and George were the first to dress and together they made their way once more to the boat-house.
In a room above the slip, in which the graceful little motor-boat was resting, Sam Hodge was found. He had arisen two hours before this time and already had eaten his breakfast and was preparing for the duties of the coming day.
It was because of Sam’s own choice that the room he occupied had been assigned him. And what a strange room it was. Sam had brought many of his own belongings among which were various pictures of the human anatomy, both external and internal. A life-size dummy stood in one corner of the room, the expression on its face being almost human in its dolefulness. In other parts of the room were legs, arms, feet and hands in various stages of completion. Sam explained that his love for the work which he did in the winter, when he was employed in the factory on Broome Street, New York, was present with him throughout the year.
“Yes, I like fooling around a boat in the summer time,” he explained, “but you can’t do that when the ice is about two feet thick. And yet if I go back to New York then I am all out of practice with my feet and legs and arms, so the only thing for me to do is to keep in the game.  I’m finishing up that dummy,” explained Sam to the boys when they entered. “One arm is a bit too long and one of the feet ought to have a number four shoe and the other about a number nine. I have seen people that way, but not very often.”
“I should think you would wake up in the night with the nightmare,” laughed George. “I think I should if I looked out and saw somebody over in the corner of the room still, staring and silent.”
“Yes, some folks is easily scared,” acknowledged Sam. “I’ve been over to Alexandria Bay,” he added.
“When?” inquired Fred quickly.
“Oh, I guess I’ve been over two or three times. I’ve been asking some questions about those men that run the Varmint II.”
“What did you find out about them?” inquired both boys eagerly.
“Accordin’ to what I heard they aren’t much good.”
“What do you mean?”
“Why, I think they are a tough lot,” said Sam, shaking his head. “The two fellows that own the boat are both of them sons of very rich men, who give them all the money they want to use. It hasn’t done the youngsters any good, I guess, from what I heard. They bought the motor-boat expecting that there wouldn’t be anything on the river that could touch her. They say they are pretty sore now that they have found that there is a boat which may give them a hard rub and perhaps take the cup away from them after all.”
“Sam, if you win that race for us—” began Fred eagerly.
“I’m not going to win your race,” broke in Sam. “I’ve heard you say that you’re going to do the steering yourself and if you are, why the only thing I can do is to be a sort of court of appeals. I’ll be there to help you out if something goes wrong. Now, we’re up against a pretty serious proposition. Those fellows are bound to win that race and if they can’t win it one way they are goin’ to win it another.”
“I don’t see how they can win, Sam, if they don’t go faster than we do.”
“Maybe they can win,” suggested Sam, “if we go slower than they do.”
“That’s the same thing,” laughed George.
“Not by a jugful.”
“Why isn’t it?”
“Why, they may not be goin’ so very fast and yet if our boat isn’t in good shape it may be that they’ll keep ahead of us and beat us.”
“Well, that’s just what you’re here for,” said Fred; “to see that nothing does happen to us or to our boat.”
“Are you goin’ to take them girls along that you had yesterday?” inquired Sam abruptly.
“Do you mean in the race?” asked Fred.
“What did you think I meant?”
“Well, we’re not going to take them.”
“Then maybe there’ll be a chance to win out. I wouldn’t promise anything with them on board, especially one of them. She’s all right, but she would want to steer the boat and talk to the crew when it might be that the whole race was dependin’ on what we were doin’ right then and there.”
“No, you can rest easy about that,” said Fred. “There won’t be anybody on board except the Go Ahead boys and you.”
“Well, then,” said Sam, “if that’s the case then we’ll have to keep a sharp watch on the Black Growler.”
Sam’s manner more than the words he spoke impressed the boys with the fact that he was holding back something that he had heard or knew concerning the possibilities of trouble for the swift little motor-boat. Just what they were, neither Fred nor George could conjecture. Their confidence in Sam was great and when they departed from the boat-house they made light of his fears.

“There has to be somebody,” said Fred, “to take the joy out of life. It wouldn’t be worth living if that wasn’t so.”
“Well, Sam does his best,” said George with a laugh, “and the only reason why he doesn’t succeed is because his bark is worse than his bite. We know he doesn’t mean half he says.”
“But why does he seem so worried about something happening to the Black Growler?”
“Oh, I don’t know,” said George. “That’s just one of his notions, I guess.”
It was not long, however, before both boys were excitedly aware that Sam’s forebodings had been based upon a knowledge greater than that possessed by any of the Go Ahead boys.

PullApprove is configured by a .pullapprove.yml
file, which is placed
in the root of your repo.
The basic idea is to organize your reviews into review groups
. Groups might
be split by language or specific areas of your codebase, or
instead might be different types of review that need to be done (e.g. "security"
or "design").
However you decide to organize your groups, you can use the group conditions
to determine when each group is asked to review a PR. When the conditions are met, the group is considered active.
When it is your turn to provide a review, we'll add you as a "requested reviewer" in GitHub. To review the PR, use the interface on github.com to approve or request changes.
A PR is considered approved when all active groups have submitted the required number of approvals. When this happens, we'll send a "success" status check to GitHub, which you can make a requirement of any protected branches.

Test passes if you see two rectangles, one green and one blue, as described below.
The green rectangle should contain a list with items numbered/marked as such: the first two items should be numbered with small latin letters, starting with d. The next three items should be bulleted with a circle. The numbers/bullets should all be inside the green rectangle.
The blue rectangle should contain a list with items numbered/marked as such: the first three items should be numbered with small latin letters, starting with a. The next two items should be bulleted with a circle. The numbers/bullets should all be outside the blue rectangle.


The first chapter of Search Inside Yourself by Chade-Meng Tan offered insight about mindfulness and emotional intelligence.
Mindfulness is defined as 'moment to moment non-judgemental awareness' and/or 'bicep curls for the brain'.
Emotional intelligence (EI) is defined as a 'collection of emotional skills'.
Of particular importance is Chade-Meng's assertion that EI is trainable via:
- attention training e.g. 2 minutes of mindfulness
- self-knowledge and mastery e.g understanding the differences between existential, experiential and physiological selfhood
- creating useful mental habits e.g wishing happiness for each person you meet.
I have been practicing meditation and mindfulness since the beginning of the course and I believe it has gradually improved my ability to be present with dev tasks and loved ones. I plan to continue doing my brain bicep curls!

About
Hello visitor! My name is Michele Piccolini.
I could tell you that I studied
Physics and then Stochastics and Data Science.
That I am now one third Mathematician,
one third Physicist, one third Data Scientist. A monstrous mixture,
a chimera of technical arts.
But this would not truly communicate who I am.
Labels and titles mean little. Don't they?
In order to tell you who I am, let me summon the concept of
duck typing,
which goes like this:
When I see a bird that walks like a duck and swims like a
duck and quacks like a duck, I call that bird a duck.
The meaning is: you are entirely defined by what you do, daily,
and not by what you are supposed to do.
And what I love and what I try to cram in my days as much as I can
is coding. I am someone who loves to code.
This is what I am.

10k 1:1 Mixture of Raji and Jurkat Cells Multiplexed¶
Dataset: 10k 1:1 Mixture of Raji and Jurkat Cells Multiplexed, 2 CMOs
The detailed description of this dataset can be found here.
Preparation¶
Fastq files and feature barcodes are prepared as described here.
QC¶
Threshold: one mismatch¶
In the qc
subcommand, if -1
(read 1) is omitted, bulk mode is enabled. The purpose of bulk mode is to help design and qc feature barcoding assays before the actual single cell experiments. For instance, you may want to estimate 1) how many reads have valid feature barcodes. This may reflect the specificity of the primers used for library construction and could suggest the number of reads needed for sequencing; 2) the distribution of feature barcodes. This reflects the biological aspect of the design.
Use -2
to specify read 2, and -f
to specify feature barcodes. Search range on reads 2 can be controlled by -r2_c
. In this example, only one mismatch is allowed for feature barcode matching (set by -fb_m
). Use -n
to specify the number of reads to analyze (None
is to analyze all reads provided in the fastq file). By default, the distribution of feature barcodes detected is summarized in qc/feature_barcode_frequency.csv
.

Result summary.
98.3% (212,402,382 / 216,070,514) of reads have valid feature barcodes. CMO301_ATGAGGAATTCCTGC and CMO302_CATGCCAATAGAGCG are the most abundant CMOs. They account for all most all of the valid reads. Although the valid read ratio is 1.663171 (132,435,325 / 79,628,216), cells labeled with them separately are mixed at 1: 1 ratio. See here for more details.

# RSpec Mocks
rspec-mocks is a test-double framework for rspec with support for method stubs, fakes, and message expectations on generated test-doubles and real objects alike.
## Install
gem install rspec # for rspec-core, rspec-expectations, rspec-mocks gem install rspec-mocks # for rspec-mocks only
## Test Doubles
A Test Double is an object that stands in for a real object in a test. RSpec creates test doubles that support method stubs and message expectations.
```ruby book = double(“book”) ```
## Method Stubs
A method stub is an implementation that returns a pre-determined value. Method stubs can be declared on test doubles or real objects using the same syntax. rspec-mocks supports 3 forms for declaring method stubs:
```ruby book.stub(:title) { “The RSpec Book” } book.stub(:title => “The RSpec Book”) book.stub(:title).and_return(“The RSpec Book”) ```
You can also use this shortcut, which creates a test double and declares a method stub in one statement:
```ruby book = double(“book”, :title => “The RSpec Book”) ```
The first argment is a name, which is used for documentation and appears in failure messages. If you don’t care about the name, you can leave it out, making the combined instantiation/stub declaration very terse:
```ruby double(:foo => ‘bar’) ```
This is particularly nice when providing a list of test doubles to a method that iterates through them:
```ruby order.calculate_total_price(stub(:price => 1.99),stub(:price => 2.99)) ```
## Consecutive return values
When a stub might be invoked more than once, you can provide additional arguments to `and_return`. The invocations cycle through the list. The last value is returned for any subsequent invocations:
```ruby die.stub(:roll).and_return(1,2,3) die.roll # => 1 die.roll # => 2 die.roll # => 3 die.roll # => 3 die.roll # => 3 ```
To return an array in a single invocation, declare an array:
```ruby team.stub(:players).and_return([stub(:name => “David”)]) ```
## Message Expectations
A message expectation is an expectation that the test double will receive a message some time before the example ends. If the message is received, the expectation is satisfied. If not, the example fails.
```ruby validator = double(“validator”) validator.should_receive(:validate).with(“02134”) zipcode = Zipcode.new(“02134”, validator) zipcode.valid? ```
## Nomenclature
### Mock Objects and Test Stubs
The names Mock Object and Test Stub suggest specialized Test Doubles. i.e. a Test Stub is a Test Double that only supports method stubs, and a Mock Object is a Test Double that supports message expectations and method stubs.
There is a lot of overlapping nomenclature here, and there are many variations of these patterns (fakes, spies, etc). Keep in mind that most of the time we’re talking about method-level concepts that are variations of method stubs and message expectations, and we’re applying to them to one generic kind of object: a Test Double.
### Test-Specific Extension
a.k.a. Partial Stub/Mock, a Test-Specific Extension is an extension of a real object in a system that is instrumented with test-double like behaviour in the context of a test. This technique is very common in Ruby because we often see class objects acting as global namespaces for methods. For example, in Rails:
```ruby person = double(“person”) Person.stub(:find) { person } ```
In this case we’re instrumenting Person to return the person object we’ve defined whenever it receives the `find` message. We can do this with any object in a system because rspec-mocks adds the `stub` and `should_receive` methods to every object. When we use either, RSpec replaces the method we’re stubbing or mocking with its own test-double-like method. At the end of the example, RSpec verifies any message expectations, and then restores the original methods.
## Expecting Arguments
```ruby double.should_receive(:msg).with(*args) double.should_not_receive(:msg).with(*args) ```
## Argument Matchers
Arguments that are passed to `with` are compared with actual arguments received using ==. In cases in which you want to specify things about the arguments rather than the arguments themselves, you can use any of the matchers that ship with rspec-expectations. They don’t all make syntactic sense (they were primarily designed for use with RSpec::Expectations), but you are free to create your own custom RSpec::Matchers.
rspec-mocks also adds some keyword Symbols that you can use to specify certain kinds of arguments:
```ruby double.should_receive(:msg).with(no_args()) double.should_receive(:msg).with(any_args()) double.should_receive(:msg).with(1, kind_of(Numeric), “b”) 2nd argument can any kind of Numeric double.should_receive(:msg).with(1, boolean(), “b”) 2nd argument can true or false double.should_receive(:msg).with(1, /abc/, “b”) 2nd argument can be any String matching the submitted Regexp double.should_receive(:msg).with(1, anything(), “b”) 2nd argument can be anything at all double.should_receive(:msg).with(1, ducktype(:abs, :div), “b”)
#2nd argument can be object that responds to #abs and #div
```
## Receive Counts
```ruby double.should_receive(:msg).once double.should_receive(:msg).twice double.should_receive(:msg).exactly(n).times double.should_receive(:msg).at_least(:once) double.should_receive(:msg).at_least(:twice) double.should_receive(:msg).at_least(n).times double.should_receive(:msg).at_most(:once) double.should_receive(:msg).at_most(:twice) double.should_receive(:msg).at_most(n).times double.should_receive(:msg).any_number_of_times ```
## Ordering
```ruby double.should_receive(:msg).ordered double.should_receive(:other_msg).ordered
#This will fail if the messages are received out of order
```
## Setting Reponses
Whether you are setting a message expectation or a method stub, you can tell the object precisely how to respond. The most generic way is to pass a block to `stub` or `should_receive`:
```ruby double.should_receive(:msg) { value } ```
When the double receives the `msg` message, it evaluates the block and returns the result.
```ruby double.should_receive(:msg).and_return(value) double.should_receive(:msg).exactly(3).times.and_return(value1, value2, value3)
# returns value1 the first time, value2 the second, etc
double.should_receive(:msg).and_raise(error)
#error can be an instantiated object or a class #if it is a class, it must be instantiable with no args
double.should_receive(:msg).and_throw(:msg) double.should_receive(:msg).and_yield(values,to,yield) double.should_receive(:msg).and_yield(values,to,yield).and_yield(some,other,values,this,time)
# for methods that yield to a block multiple times
```
Any of these responses can be applied to a stub as well
```ruby double.stub(:msg).and_return(value) double.stub(:msg).and_return(value1, value2, value3) double.stub(:msg).and_raise(error) double.stub(:msg).and_throw(:msg) double.stub(:msg).and_yield(values,to,yield) double.stub(:msg).and_yield(values,to,yield).and_yield(some,other,values,this,time) ```
## Arbitrary Handling
Once in a while you’ll find that the available expectations don’t solve the particular problem you are trying to solve. Imagine that you expect the message to come with an Array argument that has a specific length, but you don’t care what is in it. You could do this:
```ruby double.should_receive(:msg) do |arg|
arg.size.should eq(7)
end ```
## Combining Expectation Details
Combining the message name with specific arguments, receive counts and responses you can get quite a bit of detail in your expectations:
```ruby double.should_receive(:<<).with(“illegal value”).once.and_raise(ArgumentError) ```
While this is a good thing when you really need it, you probably don’t really need it! Take care to specify only the things that matter to the behavior of your code.
