I remember as early as 2012, if not even earlier, one of my life goals was to become a Java Developer. I've slowly built my foundation since then. I took on a job as a receptionist, and used much of my spare time on self-improvement, taking care of my friends/ family, decluttering, reading books, and taking college courses here and there.
This past year and a half I've buckled down, and taken to studying computer science full time. When I do need my mind to take a breather, I do take in a fair amount of anime, old films, sci fi, superhero movies and various genres of music. I also have recently taken to Islamic patterning and other forms of geometric art as a hobby.
The purpose of this assignment was to use Bootstrap to develop a resume. I have utilized this very beautiful Start Bootstrap - Resume template to implement this resume. So I extend my thanks to those developers for providing this for free. (I only tweaked CSS attributes, changed content, and added my home icon that leads back to my main page.) The source code can be found at: https://github.com/BlackrockDigital/startbootstrap-resume.

Testing Node.js with Mocha and Chai

Why Test?
Before diving in it’s important that you understand why tests are necessary.
Grab the Node/Express sample CRUD application from the repository:
$ git clone https://github.com/mjhea0/node-mocha-chai-tutorial.git
$ git checkout tags/v1
Once you have v1 of the app, manually go through it and test each of the CRUD functions via cURL (or HTTPie or Postman):
- Add new blobs
- View all blobs
- View a single blob
- Update a single blob
- Delete a single blob
This is a tedious process. What if you had to go through this same manual process every single time a new feature got added to the application? That would not only be a massive misuse of time - but unreliable as well. Hence the need for setting up a testing framework for automating the testing of the application, so you can run hundreds of tests in a matter of seconds.
With that, install Mocha:
$ npm install -g<EMAIL_ADDRESS>We installed this globally so we’ll be able to run
mocha
from the terminal.
Structure
To set up the basic tests, create a new folder called “test” in the project root, then within that folder add a file called test-server.js. Your file/folder structure should now look like:
├── package.json
├── server
│ ├── app.js
│ ├── models
│ │ └── blob.js
│ └── routes
│ └── index.js
└── test
└── test-server.js
Now add the following code to the new file:
describe('Blobs', function() {
it('should list ALL blobs on /blobs GET');
it('should list a SINGLE blob on /blob/<id> GET');
it('should add a SINGLE blob on /blobs POST');
it('should update a SINGLE blob on /blob/<id> PUT');
it('should delete a SINGLE blob on /blob/<id> DELETE');
});
Although this is just boilerplate, pay attention to the describe()
block and it()
statements. describe()
is used for grouping tests in a logical manner. Meanwhile, the it()
statements contain each individual test case, which generally (err, should) test a single feature or edge case.
Logic
To add the necessary logic, we’ll utilize Chai (v3.2.0), an assertion library, and chai-http (v 1.0.0), for making the actual HTTP requests and then testing the responses.
Install them both now:
$ npm install<EMAIL_ADDRESS><EMAIL_ADDRESS>--save-dev
Then update test-server.js, like so:
var chai = require('chai');
var chaiHttp = require('chai-http');
var server = require('../server/app');
var should = chai.should();
chai.use(chaiHttp);
describe('Blobs', function() {
it('should list ALL blobs on /blobs GET');
it('should list a SINGLE blob on /blob/<id> GET');
it('should add a SINGLE blob on /blobs POST');
it('should update a SINGLE blob on /blob/<id> PUT');
it('should delete a SINGLE blob on /blob/<id> DELETE');
});
Here, we required the new packages, chai
and chai-http
, and our app.js file in order to make requests to the app. We also used the should
assertion library so we can utilize BDD-style assertions.
One of the powerful aspects of Chai is that it allows you to choose the type of assertion style you’d like to use. Check out the Assertion Style Guide for more info. Also, aside for the assertion libraries included with Chai, there are a number of other libraries available via NPM and Github.
Now we can write our tests…
Test - GET (all)
Update the first it()
statement:
it('should list ALL blobs on /blobs GET', function(done) {
chai.request(server)
.get('/blobs')
.end(function(err, res){
res.should.have.status(200);
done();
});
});
So, we passed an anonymous function with a single argument of done
(a function) to the it()
statement. This argument ends the test case when called - e.g., done()
. The test itself is simple: We made a GET request to the /blobs
endpoint and then asserted that the response contained a 200 HTTP status code.
Simple, right?
To test, simply run mocha
; and if all went well, you should see:
$ mocha
Blobs
Connected to Database!
GET /blobs 200 19.621 ms - 2
✓ should list ALL blobs on /blobs GET (43ms)
- should list a SINGLE blob on /blob/<id> GET
- should add a SINGLE blob on /blobs POST
- should update a SINGLE blob on /blob/<id> PUT
- should delete a SINGLE blob on /blob/<id> DELETE
1 passing (72ms)
4 pending
Since testing the status code alone isn’t very significant, let’s add some more assertions:
it('should list ALL blobs on /blobs GET', function(done) {
chai.request(server)
.get('/blobs')
.end(function(err, res){
res.should.have.status(200);
res.should.be.json;
res.body.should.be.a('array');
done();
});
});
This should be straightforward, since these assertions read like plain English. Run the test suite again. It passes, right? This test still isn’t complete, since we’re not testing any of the actual data being returned. We’ll get to that shortly.
How about testing a POST request…
Test - POST
Based on the code within index.js, when a new “blob” is successfully added, we should see the following response:
{
"SUCCESS": {
"__v": 0,
"name": "name",
"lastName": "lastname",
"_id": "some-unique-id"
}
}
Need proof? Test this out by logging
{'SUCCESS': newBlob}
to the console, and then run a manual test to see what gets logged.
With that, think about how you would write/structure your assertions to test this…
it('should add a SINGLE blob on /blobs POST', function(done) {
chai.request(server)
.post('/blobs')
.send({'name': 'Java', 'lastName': 'Script'})
.end(function(err, res){
res.should.have.status(200);
res.should.be.json;
res.body.should.be.a('object');
res.body.should.have.property('SUCCESS');
res.body.SUCCESS.should.be.a('object');
res.body.SUCCESS.should.have.property('name');
res.body.SUCCESS.should.have.property('lastName');
res.body.SUCCESS.should.have.property('_id');
res.body.SUCCESS.name.should.equal('Java');
res.body.SUCCESS.lastName.should.equal('Script');
done();
});
});
Need help understanding what’s happening here? Add console.log(res.body)
just before the first assert. Run the test to see the data contained within the response body. The test we wrote tests the actual structure and data from the response body, broken down by each individual key/value pair.
Hooks
Up to this point we have been using the main database for testing purposes, which is not ideal since we’re polluting the database with test data. Instead, let’s utilize a test database and add a dummy blob to it to assert against. To do this, we can use the beforeEach()
and afterEach()
hooks - which, as the names suggest, add and remove a dummy document to the database before and after each test case is ran.
This sounds a bit difficult, but with Mocha it’s super easy!
Start by adding a configuration file called _config.js to the “server” folder in order to specify a different database URI for testing purposes:
var config = {};
config.mongoURI = {
development: 'mongodb://localhost/node-testing',
test: 'mongodb://localhost/node-test'
};
module.exports = config;
Next, update app.js to utilize the test database when the environment variable app.settings.env
evaluates to test
. (The default is development
.)
// *** config file *** //
var config = require('./_config');
// *** mongoose *** ///
mongoose.connect(config.mongoURI[app.settings.env], function(err, res) {
if(err) {
console.log('Error connecting to the database. ' + err);
} else {
console.log('Connected to Database: ' + config.mongoURI[app.settings.env]);
}
});
Finally, update the requirements and add the hooks to the testing script:
process.env.NODE_ENV = 'test';
var chai = require('chai');
var chaiHttp = require('chai-http');
var mongoose = require("mongoose");
var server = require('../server/app');
var Blob = require("../server/models/blob");
var should = chai.should();
chai.use(chaiHttp);
describe('Blobs', function() {
Blob.collection.drop();
beforeEach(function(done){
var newBlob = new Blob({
name: 'Bat',
lastName: 'man'
});
newBlob.save(function(err) {
done();
});
});
afterEach(function(done){
Blob.collection.drop();
done();
});
...snip...
Now, before each test case, the database is cleared and a new blob is added; then, after each test, the database is cleared before the next test case is ran.
Run the tests again to ensure they still pass.
Test - GET (all)
With the hooks set up, let’s refactor the first test to assert that the blob from the beforeEach()
is part of the collection:
it('should list ALL blobs on /blobs GET', function(done) {
chai.request(server)
.get('/blobs')
.end(function(err, res){
res.should.have.status(200);
res.should.be.json;
res.body.should.be.a('array');
res.body[0].should.have.property('_id');
res.body[0].should.have.property('name');
res.body[0].should.have.property('lastName');
res.body[0].name.should.equal('Bat');
res.body[0].lastName.should.equal('man');
done();
});
});
Let’s look at the final three tests…
Test - GET (single)
it('should list a SINGLE blob on /blob/<id> GET', function(done) {
var newBlob = new Blob({
name: 'Super',
lastName: 'man'
});
newBlob.save(function(err, data) {
chai.request(server)
.get('/blob/'+data.id)
.end(function(err, res){
res.should.have.status(200);
res.should.be.json;
res.body.should.be.a('object');
res.body.should.have.property('_id');
res.body.should.have.property('name');
res.body.should.have.property('lastName');
res.body.name.should.equal('Super');
res.body.lastName.should.equal('man');
res.body._id.should.equal(data.id);
done();
});
});
});
In this test case, we first added a new blob, and then used the newly created _id
to make the request and then test the subsequent response.
Test - PUT
it('should update a SINGLE blob on /blob/<id> PUT', function(done) {
chai.request(server)
.get('/blobs')
.end(function(err, res){
chai.request(server)
.put('/blob/'+res.body[0]._id)
.send({'name': 'Spider'})
.end(function(error, response){
response.should.have.status(200);
response.should.be.json;
response.body.should.be.a('object');
response.body.should.have.property('UPDATED');
response.body.UPDATED.should.be.a('object');
response.body.UPDATED.should.have.property('name');
response.body.UPDATED.should.have.property('_id');
response.body.UPDATED.name.should.equal('Spider');
done();
});
});
});
Here, we hit the /blobs
endpoint with a GET request to grab the blob added from the beforeEach()
hook, then we simply added the _id
to the URL for the PUT request and updated the name to Spider
.
Test - DELETE
Finally…
it('should delete a SINGLE blob on /blob/<id> DELETE', function(done) {
chai.request(server)
.get('/blobs')
.end(function(err, res){
chai.request(server)
.delete('/blob/'+res.body[0]._id)
.end(function(error, response){
response.should.have.status(200);
response.should.be.json;
response.body.should.be.a('object');
response.body.should.have.property('REMOVED');
response.body.REMOVED.should.be.a('object');
response.body.REMOVED.should.have.property('name');
response.body.REMOVED.should.have.property('_id');
response.body.REMOVED.name.should.equal('Bat');
done();
});
});
});
Conclusion
Hopefully you can now see just how easy it is to test your code with Mocha and Chai. Keep practicing on your own, incorporating a true BDD approach into your workflow. Grab the final code for this tutorial from the repository.


As far as I know, in your case lstClientes must contain pointers, because std::list stores a copy of the object.
In your case, lstClientes contains objects of type Cliente, even if you push_back ClienteJuridico or ClienteNatural.
Changing lstClientes to list<Cliente*> will solve your problem.
Obviously, be careful of memory leaks.
Maybe you would use manager pointers: see http://www.cplusplus.com/reference/memory/
You must make the base's class a virtual method.
About copying, you should store pointers instead of objects (if you are allowed to).
This is kind of what you should have:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
class BaseClient {
public:
virtualvoid Display() =0;
virtual ~BaseClient() {} // Important!
// If you split header/source, put the (empty) body in the source file.
};
class JurClient : public BaseClient {
public:
virtualvoid Display() { std::cout << "Jur. Client"; }
};
class NatClient : public BaseClient {
public:
virtualvoid Display() { std::cout << "Nat. Client"; }
};
And the rest of the code should be like this:
1 2 3 4 5 6 7 8 9 10 11
std::list<std::unique_ptr<BaseClient>> clients;
clients.push_back(std::unique_ptr<BaseClient>(new JurClient()));
clients.push_back(std::unique_ptr<BaseClient>(new NatClient()));
unsignedint ClientID = 0;
for(autoconst& it : clients)
{
std::cout << "Client nr. " << ++ClientID << " is a ";
it->Display();
std::cout << std::endl;
}
Some of the code uses C++11 features (such as std::unique_ptr and range-for.
If you really want to follow a different approach, store all the infos in a single class as follows:
enum ClientType {
CT_NATURAL = 0, // = 0 is important
CT_JURIDICA,
CT_AMOUNT // must be the last one, tells us how many types are there
};
class Client {
ClientType m_ClientType;
public:
Client(ClientType t = CT_NATURAL) // If no ClientType is provided, use CT_NATURAL.
: m_ClientType(t) {}
void Display() const { // Note: Marked as const, since it doesn't modify Client itself.
// static: initialized once
// const: does not change
staticconst std::string TypeToName[CT_AMOUNT] = {
"Persona Natural",
"Persona Juridica"
};
if(m_ClientType < 0 || m_ClientType >= CT_AMOUNT)
std::cout << "Tipo no definido";
else
std::cout << TypeToName[m_ClientType];
}
};
And use as follows:
1 2 3 4 5 6 7 8 9 10 11 12
std::list<Client> clients;
clients.push_back(Client(CT_NATURAL));
clients.push_back(Client(CT_JURIDICA));
clients.push_back(Client(ClientType(42))); // client type of id 42? it does not exist, and will print Tipo no definido.
unsignedint ClientID = 0;
for(autoconst& it : clients)
{
std::cout << "Client nr. " << ++ClientID << " is a ";
it.Display();
std::cout << std::endl;
}

Man who sent chilling six-word letter to Anna Soubry jailed after warning she was 'next' after Jo Cox
Anna Soubry was sent the post, which read "COX WAS FIRST YOU ARE NEXT", by Alden Bryce Barlow, 55, from Doncaster
by James Rodger, https://www.facebook.com/jamesrodgerjournalistA man who sent a "sickening" letter to an MP, suggesting she would be murdered like Jo Cox, has been jailed.
Anna Soubry was sent the post, which read "COX WAS FIRST YOU ARE NEXT", by Alden Bryce Barlow, 55, from Doncaster.
The letter arrived at Ms Soubry's constituency office in Broxtowe, Nottingham, on October 14 this year and was opened by a member of staff, the Crown Prosecution Service (CPS) said.
Barlow admitted sending a letter conveying a threatening message and was sentenced to 12 months in jail at Sheffield Crown Court.
He was also given a 10-year restraining order against Ms Soubry, who is standing as a candidate for The Independent Group for Change (TIGfC) in the General Election.
Barlow was traced using fingerprint analysis and CCTV from the post office counter in Doncaster where he posted the letter.
Ms Soubry, leader of the TIGfC, was previously a Conservative and had several ministerial jobs under David Cameron.
Chief Crown prosecutor Gerry Wareham called the note "sickening" and "ominous" and described it as an "attack on democracy".
He said: "Ms Soubry and her staff in the constituency office understandably found the message deeply disturbing and highly offensive.
"I hope the sentence Barlow received today is of some comfort to Ms Soubry and her colleagues and a deterrent to anyone else contemplating such despicable actions against a parliamentary representative or candidate."
Mrs Cox was Labour MP for Batley and Spen when she was stabbed and shot outside a constituency surgery in Birstall, West Yorkshire, in 2016.

I’ve been fascinated by radio frequency since before I can remember.
I guess it all started with taking apart radios, phones and walkie-talkies as a kid growing up in the 80’s.
From closed system RF & CATV, to IP Networking, WiFi, CDMA, GSM, & LTE and the devices that transmit and receive them, I love it all.
Today I’m just as disruptive, but in a much cooler way.
I build and maintain scalable, hardened platforms that secure and manage the mobile phones, tablets and laptop computers that drive todays mosst innovative technologies.
I absolutely love working at companies where I am surrounded by talented people, and cutting edge technology.
I’ve had the great pleasure of working for some of the best companies in the world. I cut my teeth in RF as a System Tech at TCI Cablevision (now Time Warner) before the birth of the internet. Since then I’ve worked for Nortel Networks, Samsung, Apple, Honeywell, Southwest Airlines, Uber and now Enterprise Holdings.
When I’m not at work, I’m chillin’ at home with my wife and kids, camping, fishing or teaching myself something new. I’m currently learning Python & Javascript. I’m also an amateur DJ & vocal performer specializing in Audio Books.
I’m always interested in connecting with cool people who like to do fun stuff with computers. Reach out and tell me what you’re working on, maybe we can learn from each other! Check back for more as I build out the site!.

Switch statement
Summary
Adds a switch statement to Python.
Limitation: a switch statement cannot contain another switch statement.
There have been 2 PEPs looking at the possibility of adding a switch
statement to Python.
First, in 2001, PEP 275 made
this suggestion. This was later superceded by PEP 3103 written in 2006 by Guido van Rossum and, after a straw poll during
his keynote at PyCon 2007, he rejected it.
In order to “play” with the syntax and try to evaluate the benefit, I decided to implement it. PEP 3103 looks at various possible syntax, and I chose the one which seemed the most in line with normal Python syntax, namely version 1 B. The implementation meant to replace code like:
switch EXPR:
case EXPR_1:
SUITE
case EXPR_2:
SUITE
case in (EXPR_3, EXPR_4, ...):
SUITE
...
else:
SUITE
by:
var_name = EXPR
if var_name == EXPR_1:
SUITE
elif var_name == EXPR_2:
SUITE
elif var_name in (EXPR_3, EXPR_4, ...):
SUITE
else:
SUITE
del var_name
where var_name
is a unique variable name chosen randomly.
Note that I didn’t bother to dedent the inner SUITE
as it is
never shown to the end user and would only complicate the code.
Result
The actual result is not particularly enlightning.
PEP 3103 considers the fact that each SUITE
has two levels
of indentation to be a downside. Personally, after writing some testing
code with it (not saved anywhere), I found the fact that, due to having
all the case
statements indented make the code stand out better than
having a traditional if/elif/else
suite; so, I consider the extra
indentation to be a bonus. However, perhaps I might feel otherwise if I
always limited myself to having line with no more than 79 characters
which was the norm when the PEP was written.
switch.py
Implements something similar to version 1.B of PEP 3103
- ideas.examples.switch.add_hook(predictable_names=False, **_kwargs)[source]
Creates and adds the import hook in sys.meta_path
- ideas.examples.switch.transform_source(source, callback_params=None, **_kwargs)[source]
Replaces code like:
switch EXPR: case EXPR_1: SUITE case EXPR_2: SUITE case in EXPR_3, EXPR_4, ...: SUITE ... else: SUITE
by:
var_name = EXPR if var_name == EXPR_1: SUITE elif var_name == EXPR_2: SUITE elif var_name in EXPR_3, EXPR_4, ...: SUITE else: SUITE del var_name
Limitation: switch blocks cannot be part of a SUITE of another switch block.


Cuba Drawn in Group B of the WBSC Americas Olympic Qualifying Tournament
by ACNCuba was included in group B of the Americas Olympic Qualifying Tournament to be played in Arizona, United States, from March 22-26, 2020, in which also appear the squads of Colombia, Canada and Venezuela.
Havana, Cuba.- According to the draw made by the World Baseball and Softball Confederation (WBSC) in the middle of its third congress that is based in Japan, the other Pool is made up by USA, Puerto Rico, Dominican Republic and Nicaragua.
This contest will award a direct berth to Tokyo 2020 and two tickets for the last Olympic qualifying tournament, which will has an intercontinental status in Chinese Taipei, from April 1-5.
The best two teams of each group will advance to the Super Round, in which they will face the sides of the other pool where, after the second stage of the championship, it will be defined the order that will grant the leader the fifth ticket to Tokyo 2020 Olympics.
In addition, those finishing second and third will get tickets to the intercontinental qualifiers with seat in Chinese Taipei, which will also be attended by Holland, China, Australia and the hosts.
Cuba will debut on March 22nd against Venezuela, one day later they will face Canada and close the preliminary phase versus Colombia; the Super Round is scheduled for March 25 and 26.
In the last Pan American Games, the Caribbean island lost with two of the members of this group B: Colombia and Canada, in addition to falling again to the latter in the preliminary round of the WBSC Premier 12 Tournament.
Israel (winner of the Europe-Africa qualifiers), South Korea and Mexico (Premier 12) and Japan as host already earned their berths to Tokyo 2020 Olympic Games. (acn)


I have an idea. It’s an idea I’ve been working on for quite a while now, and it is beginning to take shape, but I don’t think I am allowed to bring my idea to life. Now that sounds weird, right? Censorship isn’t something we are usually okay with, as a free society, and yet in the games industry, it’s par for the course.
Picture this: a first-person shooter-slash-adventure game, based in a city. So far, so sort-of-GTA, right? Here’s the kicker: it’s about drug addiction, the underbelly of society and what it’s like to be dragged kicking and screaming down into it.
This is not a game that glorifies drugs. This is not a game where shooting up some speed makes you “faster”, or morphine giving you more health. This is a game where you must made ends meet, make terrible decisions to feed your addiction or face the horrible withdrawals, and the wrath of the Association – deal drugs, or very bad things happen to people you love. It’s dark, it’s gloomy, it’s going to be hard to play through. It won’t have a happy ending. It’s a real life rendition of what those situations are actually like.
But I am not allowed to make it. Well, okay, I am, as an indie PC game perhaps, but if I wanted to put it on Steam? If I wanted to put it on the upcoming PS4? I can’t. Drugs, even if they are handled this way, are off limits, but screwing a hooker and murdering her (GTA)? Mowing down civilians (in a frankly unaffecting scene from Modern Warfare 2)? These are fine, but a realistic portrayl of drug dealing and the horrors that surround the scene, that is not.
I cannot understand societies take on this. For the record, I’m against the war on drugs; half the things I want to delve into in this game are caused by it directly. But I am not allowed to tackle this issue, if I want to see success? This is not going to just be an “issue” game: I want it to be gripping, exciting, and a massively memorable experience. I want it to be a good game. But I also want to say something: and I’m not allowed.

public interface IContentManagerSession
IContentManager
. A
session is a group of zero or more downloads/uploads that are logically related.
Downloads are performed with
retrieveContent(IContent, IDownloadHandler)
, which takes an
IDownloadHandler
as an argument. The IDownloadHandler
receives the download (possibly in another thread).
Uploads are performed with
#storeContent(InputStream in, IUploadHandler)
, which takes an
IUploadHandler
as an argument. The IUploadHandler
receives the resulting IContent (possibly in another thread).
If one download or upload is canceled, then implementors should cause
all downloads and uploads to be canceled. Any subsequent call to one of
IContentManagerSession
's methods will result in an
OperationCanceledException
.
Sample usage:
IContentManager manager; IContent content1, content2; IContentManagerSession session = manager.createSession("Sample download", 2, null); DownloadAdapter dl = new DownloadAdapter() { public void downloadCompletedEvent(IContent content) { System.out.println("Download completed"); } }; session.retrieveContent(content1, dl); session.retrieveContent(content2, dl); session.join(); session.getErrorStatus();

You're paying too much for car insurance. But there's a solution.
Michigan drivers pay the nation's highest car insurance premiums, averaging $2,400 a year, while nearby states pay less than half that amount.
How do we fix it? The solution is Drivers Choice, a plan to cut rates an average 20% to 50% statewide.
Michigan drivers are forced to pay for unlimited lifetime health insurance, something no other state in America does.
And car insurance companies in Michigan pay outrageous rates for medical treatments like MRIs, CT scans and physical therapy — three to four times as much as private health insurance — because there are no set rates for those treatments.
Drivers Choice would give drivers the freedom to choose the level of health coverage they can afford, while still preserving the best levels of coverage in the nation.
And it would set fee rates for medical treatments so that car insurance companies get the same discounts bargained for Medicare and private health insurance companies.
Tired of paying too much? Find out about Drivers Choice. It's time to fix Michigan's broken no-fault car insurance system. We can't afford not to.
Naomi Williams, Detroit
Mrs. Williams, 85, a retired registered nurse for the Veterans Administration who lives on Detroit's near east side, doesnt drive as often as she used to and hasn't received a ticket in decades. Still, AAA Michigan quoted her $1,542.74 for a six-month policy for her 2015 Buick Verano in 2017. "It's a sacrifice, but I do pay it," she says.
Under the proposed Driver's Choice legislation, Michigan drivers will have more choice in their auto insurance medical coverage that would allow them to save an average of 20% - 50% on their insurance premiums. Choose the option below that best describes you to find out how much you can save based on your actual current insurance bill:*
* Please note this is only an estimate, actual insurance costs will vary.

Sifter is an application produced by a small team of five developers as part of the Digital Tribes Hackathon. We aimed to make an aptitude test for remote controllers disguised as a game. Research has suggested that gamifying the learning process can help make material more enjoyable and also cause a deeper level of understanding.
When you use game-based assessments as part of your recruitment process, you’re not only identifying the best candidates quickly, accurately, and enjoyably. You’re also telling your prospective employees that you’re an innovative employer and that you care about the experience your candidates go through to become a part of your team. Candidates become immersed in the games and forget they’re completing an assessment, which means they’re less stressed, providing you with more authentic data about their performance.
While playing Sifter, the user will be tested in multiple ways. Sifter tests reaction time. It tests the user’s ability to think spatially while under pressure. It tests solving intense problems while multitasking. Most importantly, it tests overall cognitive ability and contains specific components to enhance mental agility and attention span.
The abilities measured by Sifter are critical for almost every role, from entry-level to executive. We feel that Sifter can be a valuable tool for not only finding the right candidate for a particular job, but also for furthering training for employees of any skill level.
Developers:
James J. Sewell, Athena Floudas, Jesse Sewell, Kenji Hirabayashi, Patrick Hildreth

This app is written in Javascript and is therefore compatible with all modern web browsers. We have written the code to be lightweight so it can can be quickly and easily adapted to work with smaller devices such as tablets and mobile screens.

Abstract: We present a method to distinguish direct connections between two neurons from common input originating from other, unmeasured neurons. The distinction is computed from the spike times of the two neurons in response to a white noise stimulus. Although the method is based on a highly idealized linear-nonlinear approximation of neural response, we demonstrate via simulation that the approach can work with a more realistic, integrate-and-ﬁre neuron model. We propose that the approach exempliﬁed by this analysis may yield viable tools for reconstructing stimulus-driven neural networks from data gathered in neurophysiology experiments.

Too many tools and frameworks
The definitive guide to the javascript tooling landscape in 2015.
By Adam Morse
Theodore Sturgeon was a science fiction author, critic, and the basis for Kurt Vonnegut's recurring character Kilgore Trout. He was prolific, authoring over 200 pieces himself and critiquing around 400 others.
In 1958 he published a piece in Venture proclaiming what he called "Sturgeon's Revelation"
I repeat Sturgeon's Revelation, which was wrung out of me after twenty years of wearying defense of science fiction against attacks of people who used the worst examples of the field for ammunition, and whose conclusion was that ninety percent of SF is crud.  In other words, the claim (or fact) that 90% of science fiction is crap is ultimately uninformative, because science fiction conforms to the same trends of quality as all other artforms.
You don't have to bounce a tennis ball very far in San Francisco before it will hit two developers complaining about how many js tools/frameworks there are for development in 2015 and how much unneccessary complexity they add. Doing a search on twitter for 'too many js tools' or 'yet another js framework' returns... a lot of people lamenting the current state of affairs.
This is most likely, the wrong conversation for us as a community, to be having. The presence of bad tools - shouldn't discourage us from wanting more tools or frameworks. There are more books published in a single day than I will ever be able to read in my lifetime. But this does not make me sad. Or overwhelm me. Mostly I think about how excited I am to read the best books that are being published. And this is where we should push the conversation. How do we build better tools? What does that look like?


Light Loop Methods | |
This is the recommended API for looping over light source samples. | |
| AI_API void | AiLightsPrepare (AtShaderGlobals *sg) |

| AI_API void | AiLightsResetCache (AtShaderGlobals *sg) |
| Reset the light cache before running another light loop. More... | |
Light Getter Methods | |
These getters are to avoid slow AiNodeGet*() calls to access light parameters. Only the most common attributes are exposed for now. | |
| AI_API AI_PURE AtRGB | AiLightGetColor (const AtNode *node) |
| Fast getter method for parameter color. | |
| AI_API AI_PURE float | AiLightGetIntensity (const AtNode *node) |
| Fast getter method for parameter intensity. | |
| AI_API AI_PURE bool | AiLightGetAffectDiffuse (const AtNode *node) |
| DEPRECATED: Fast getter method for parameter affect_diffuse. | |
| AI_API AI_PURE bool | AiLightGetAffectSpecular (const AtNode *node) |
| DEPRECATED: Fast getter method for parameter affect_specular. | |
| AI_API AI_PURE float | AiLightGetDiffuse (const AtNode *node) |
| Fast getter method for the light's diffuse shading multiplier. | |
| AI_API AI_PURE float | AiLightGetSpecular (const AtNode *node) |
| Fast getter method for the light's specular shading multiplier. | |
| AI_API AI_PURE float | AiLightGetSSS (const AtNode *node) |
| Fast getter method for the light's SSS shading multiplier. | |
| AI_API AI_PURE float | AiLightGetVolume (const AtNode *node) |
| Fast getter method for the light's volume shading multiplier. | |
| AI_API void AiLightsPrepare | ( | AtShaderGlobals * | sg | ) |
Initialize light loop.
Prepares the given shader globals for looping over lights. The current position and normal are cached so that the evaluation of lights (which might require evaluating filters and tracing shadow rays) can be skipped if nothing changes.
| [in,out] | sg | the shader globals context |
| AI_API bool AiLightsGetSample | ( | AtShaderGlobals * | sg | ) |
Get a sample within a light loop.
After AiLightsPrepare()
has been called, this function should be called inside a while loop. The call returns true if a valid light sample has been set, in which case all the light source related fields in the shader globals context are set:
sg->Li
– incident radiance, same as sg->Liu
* (1 - sg->Lo
)sg->Ld
– normalized vector towards the light samplesg->Lo
– RGB occlusion factor, where (1,1,1) means fully occludedsg->Liu
– unoccluded incident radiance (this is the same as sg->Li
without considering occlusion)sg->Ldist
– distance towards the light sourcesg->we
– weight of the light samplesg->Lp
– pointer to the light's AtNode| [in,out] | sg | the shader globals context |
| AI_API AtRGB AiLightsGetShadowMatte | ( | AtShaderGlobals * | sg | ) |
Get the shadow/occlusion value for the current shading point and the active set of lights.
Shadow occlusion is calculated by accumulating all of the sg->Lo
values for each of the lights weighted by their respective sg->we
values, and then determining the maximum matte value of all the lights. It is this maximum value which is returned. This value can never be greater than 1.0.
It is not neccessary to call AiLightsPrepare()
prior to calling this function. If the light samples have not been set up, then this function will prepare them by automatically calling AiLightsPrepare()
.
| sg | the shader globals context |
| AI_API void AiLightsResetCache | ( | AtShaderGlobals * | sg | ) |
Reset the light cache before running another light loop.
The after calling AiLightsPrepare()
various lighting data are cached so that subsequent calls will incur no overhead. However, if certain values change in the shader globals, that cached lighting data may not be valid and a reset is necessary to compute new data. This is particularly true if you wish to switch from hemispherical lighting to full-sphere lighting, change the surface normal or position, or change tracesets for shadow rays in a particular light loop.

java.lang.Object org.codehaus.aspectwerkz.util.SequencedHashMap
public class SequencedHashMap
A map of objects whose mapping entries are sequenced based on the order in which they were added. This data structure has fast O(1) search time, deletion time, and insertion time.
Although this map is sequenced, it cannot implement
List
because of incompatible interface
definitions. The remove methods in List and Map have different return values (see:
and
Map.remove(Object)
).
This class is not thread safe. When a thread safe implementation is required, use
Collections.synchronizedMap(Map)
as it is documented, or use explicit synchronization controls.

Sigh... I've decided that PyDispatcher is probably the right thing for SQLObject events -- I think it's a predictable and easy-to-understand package for this context, and I really prefer phrasing this in terms of events. But PyDispatcher conflicts with RuleDispatch, because they both use the package dispatch. Not a problem unless you want to use them both at once. Which is certain to happen, since TurboGears added the JSON code I mentioned (that uses RuleDispatch), and also uses SQLObject.
This is annoying. Maybe I'll think again about using RuleDispatch... but I feel unnecessarily forced into the decision.
Have you looked at FibraNet?
It is much simpler than PyDispatcher, and may suit your needs better.
PyDispatcher isn't that complicated, really. Not very complicated at all, at least when I consider what I want to do with it. And it seems better documented than FibraNet.
# Ian Bicking
I agree with the general lament: that an unambiguous namespace means having to deal with packages that have the same name.
You can, of course, get around that in any specific code with import foo as bar.
In this specific case, though, should the JSON code just be reimplemented using PyDispatcher? I must admit to sharing your preference for the simple, hugely flexible PyDispatcher.
# Ben Finney
I may be a little naive about event dispatching mechanisms, but when it comes to simplicity, how simple can they get, and exactly what flexibility is required?
I've used FibraNet (back when it was just called 'EventNet'), the event/signal mechanism in PGU, and PyDispatcher. From my experience, EventNet was the most simple. One line to post an event:
eventnet.driver.post('my_event', arg1=something, arg2=something_else)
and one line to register a callable to receive an event:
@eventnet.driver.subscribe('my_event')
def my_event_handler(event): print event.name, event.arg1, event.arg2
EventNet does force you to keep track of references, and explicitly unsubscribe event handlers, as it does not use weak references. This can result in some extra code.
I've found writing code like this can be either very elegant, or very confusing. This situation gets amplified (for better or worse) once you start using the eventnet.net module, which works well for simple IPC, though I do not know how safe it is.
I am curious, how exactly are you planning to use an event dispatcher in SQLObject, and what problems will it help solve?
How is this simpler:
eventnet.driver.post('my_event', arg1=something, arg2=something_else)Than this:
dispatcher.send('my_event', arg1=something, arg2=something_else)Or listening with:
dispatcher.connect(my_event_handler, 'my_event')It's not a decorator, but that would be very easy to implement. PyDispatcher also has has the concept of "sender", which I find useful, as I'm actually expecting to listen to events on a per-class basis (and SQLObject classes are the senders).
The events I'm proposing are listed in sqlobject.events in the repository -- it could quickly become a core part of how basic concepts like joins and columns are implemented. E.g., a column with a cascade=True setting would listen for a delete event.
# Ian Bicking
PyDispatcher doesn't really apply to the JSON code, so that's not an option. The name conflict doesn't help, because you simply can't have two distributions loaded with the same top-level name (except maybe with the technique PJE mentioned, though that requires repackaging the libraries, at which point I could just rename the package).
# Ian Bicking
Well, I was suggesting that if enough people asked for it, then the authors of the respective packages (i.e., me and Patrick O'Brien) would probably be willing to include that code for compatibility's sake.
Patrick doesn't do much with PyDispatcher these days AFAIK, but I'd certainly be willing to incorporate changes that would let the two packages coexist. Heck, if I recall correctly from our earlier discussion the two packages can actually be dumped into the same directory and both continue to function as expected.
Hmm, should have finished reading the whole comment thread. Apparently Patrick is all over it :) .
I'm more than happy to defer to you, Mike, since you've been shepherding the code for some time now. I appreciate all the work you've done to make the code available, fix bugs, add enhancements, etc.
You know, you could package one or the other so it's a namespace package, as long as there aren't any conflicting names within the two dispatch packages. Just add something like:
try: from pkg_resources import declare_namespace except ImportError: pass else: declare_namespace(__name__)to the end of both dispatch/__init__.py files. The only downside is that it forces both packages' __init__ modules to be loaded when you import dispatch.
I agree, this situation is unfortunate. I would gladly support any solution that will make it easier for people to use both packages. In the mean time, what we have done with Schevo is simply included pydispatcher as a subpackage of schevo. Call it a fork, if you will. Then we use it like this:
from schevo.dispatcher import dispatcher from schevo.dispatcher.errors import DispatcherKeyErrorI don't think this is the ideal solution. And certainly Eggs makes dependency management much more palatable than it used to be, so someone may come up with something better. But if a simple solution isn't forthcoming, then sometimes you just do what you gotta do. You would not offend me in the slightest if you took the same approach with SQLObject. :-)
Yeah, I'm thinking about doing that as well. I could repackage it as pydispatcher, but that makes the installation harder to handle, because I'd have to give that new package a name, and people couldn't install strictly from PyPI if they were using easy_install (unless I registered it, which I don't want to do... unless maybe it was a hidden registration, which might actually work...)

Luxury hotel, Ritz-Carlton, open for business in Perth
Perth’s newest luxury hotel is officially open for business with the launch of the Ritz-Carlton’s 100th hotel on Barrack Street this morning.
The hotel offers 205 guest rooms including 19 suites, which feature views of Perth city and the Swan River.
It is home to Perth’s newest culinary sensation, Hearth, which The West Australian food editor Rob Broadfield predicts will be within reach of international acclaim.
After a smoking ceremony at 5.30am, stakeholders and guests met outside the front door of the hotel at 9am for a welcome to country and ribbon-cutting followed by a toast inside the lobby.
Ritz-Carlton Perth general manager Dario Orsini said the design that had been weaved into the material and fabric if the hotel was profoundly West Australian.
“This place is packed with homages to what Western Australia has to offer to the world,” he said.
“As soon as you walk into the Ritz-Carlton Perth, you know where you are.
“Everything that you will taste, see, feel and touch here is Western Australia.”

Formed from a combination of high-CBD ERB and ACDC strains, a standard Elektra bud has almost 16 percent CBD and less than 0.3 percent THC content. Developed mainly in Oregon, Elektra hemp flowers feel sticky to the touch and have an intense green color peppered with orange stripes. This sativa-dominant hybrid strain is famed for its fabulous forest scent, particularly reminiscent of pine trees.
When smoking Elektra, you might often taste an intriguing mix of tropical flavors, citrus fruits, and earthy tones. Interestingly, some of the same terpenes found in Elektra are also in mangoes, lemons, and pine leaves.

web developer | adventurer
I'm a proud Wellingtonian, but have been living in Auckland or other parts of the world for a few years now. I studied first at Victoria, and then later at University of Auckland, doing a Masters of Speech Language Therapy Practice.
I've begun an adventure in web development!
I was lacking passion for my work and my career and have been looking for something to really get my teeth into. I wanted something with creativity, flexibility and career growth, and realised web development was all that. Once I found Enspiral Dev Academy and saw what an inclusive and supportive culture there was, I knew that's what I was going to do.
There are so many exciting possibilities out there that will surely shift and change as time goes on. I'm happy putting my head down and focusing on gaining knowledge and developing skills, and then I'll be excited to take the next step.

General query requirements
See the Proximity QGraph Guide for a complete description of the QGraph language as implemented in Proximity.
Queries run from the Query Editor are always executed against the entire database.
Queries run from the Proximity Database Browser or from the command line can be optionally executed against the contents of a container.
The QGraph
DTD,
graph-query.dtd
,
must reside in the same directory as the query file.
Make sure that you copy the DTD file from
$PROX_HOME/resources
to the directory
containing the query file before executing the query.
Every query must have at least one vertex.
Every query edge must have vertices at both ends.
Queries must be connected.
Queries must remain connected after any optional or negated elements are removed.
Each vertex and edge in a query must have a unique label (name).
Proximity ignores case when matching attribute names to those in the database. Proximity obeys case when matching attribute values with those in the database.
Condition requirements
Attribute value conditions restrict query matches to objects or links that match the specified attribute value.
Existence conditions restrict query matches to objects or links that have any value for the specified attribute.
Use disjunctive normal form in prefix notation to create complex conditions from simple conditions.
Surround values (i.e., vertex and edge labels or attribute names and values) containing spaces with single quotes.
Annotation requirements
An edge incident to an annotated vertex must be annotated.
The boundary edge of an annotated subquery must be annotated.
At most, only one of two adjacent elements can be annotated; no edges are allowed between two annotated elements.
Constraint requirements
Identity constraints compare IDs with each other.
Attribute constraints compare attribute values with each other.
Mixing IDs and attribute values in a constraint is not permitted. (You may, however, compare values for different attributes as long as they are of comparable types.)
Constraints are only allowed between two vertices or two edges; mixing vertices and edges is not permitted.
No constraints are allowed between two annotated elements.
If one of two items in a constraint is annotated, the other cannot be part of an annotated subquery.
With one exception, Proximity prohibits constraints between
two edges when one of them is annotated. Proximity allows such
constraints when the vertex adjacent to the annotated edge is itself
annotated with [0..]
or
[0..
.
j
]
Constraints can only be combined with AND; OR and NOT are not allowed.
Constraints that cross subquery boundaries require that one
of the items being compared be optional (have an annotation of
[0..]
or
[0..
).
j
]
Surround values (i.e., vertex and edge labels or attribute names and values) containing spaces with single quotes.
Subquery requirements
A subquery must be a well-formed query by itself.
All subqueries must be annotated.
The boundary edge of a subquery must be annotated.
The boundary vertex of a subquery cannot be annotated.
The vertex outside the subquery connected to the boundary edge cannot be annotated.
Update requirements
The QGraph language provides full update functionality; however, Proximity currently implements only the ability to add links using queries.
A query’s match phase is distinct from its update phase; new database elements added by a query do not change a query’s matches.
New database elements added by a query are not included in the query’s results (subgraphs).
You must specify an attribute value for all new links. The attribute value must be constant—the same for all new links added by the query.
Additional Information
See the Proximity QGraph Guide for additional details on the QGraph language and it’s implementation in Proximity.
See Chapter 7, Learning Models for more information on how query elements and labels are used by Proximity’s models.
See Appendix A, Proximity Quick Reference for a summary of how to use the location bar to directly access Proximity database elements including containers and subgraphs.

Bored of solving sudokus normally? Try out this sudoku solver.
Above, is a visualization from Wikipedia, about the sudoku backtracking algorithm.
If you don’t care about any of this, and just want to crank out some computationally solved sudokus, get the code here.
After waiting on the airplane and solving another soduko from the back of a Skymiles magazine, I thought it might be fun to build a sudoku solver. At first, I was planning on implementing essentially a brute force approach, where I would try a possible combination for a cell, and then with that possible cell filled, try to fill out the cell from there. I figured this would be considered brute force.
As it turns out, that approach is a little bit more sophisticated then just basic brute force, and is actually commonly called backtracking. You can read more about it below. The algorithm makes pretty intuitive sense. You find the possible options for a given cell, and then recurse on the given sudoku from there. When you find one that is fully filled and satisfied, you just short out, and keep returning true and then you’ve got yourself the golden sudoku. The solution! Once again, if you’re just interested in grabbing the actual program, you can find it here.
The actual textbook definition of brute-force means to iterate over the entire search space, and check whether that solution is valid. So you can imagine that this would be literally generating all possible values for all open cells. This is also going to be discussed further below.
The program is pretty simple. There is a menu when you first start the program where you can enter in sudoku matrices either from another file, from stdin
, solve a default sudoku, or cycle through a directory. The only other thing to know is that the unfilled spaces on the sudoku are marked by EITHER 0 or -1. You can choose at your fancy. Let me know if there are any issues besides that.
I figured I should throw this here in case some people aren’t totally clear of the rules of sudoku or even what it is. Sudoku is a grid of 9 x 9 cells. That’s 81 cells in total. There are 9 different unique subblocks, with have 9 cells in them. Some of these cells might be filled at the start of the puzzle. There has to be one unique solution to every sudoku puzzle, or else it is not valid. The rules in terms of filling the cells are found below:
And that’s really it! Otherwise then that, it’s just filling in the cells.
Ok so the theory behind backtracking. How is this different than the brute force approach? This site has a pretty good synopsis. One that I probably wish I would have read before just blindly leaping into trying to solve this problem. As the author puts it, recursion is really the name of the game. The idea is that we pick one possible starting option out of a bunch and then we recurse on that solution. If that solution doesn’t work, then we go back to our original assertion, and we try another. Then we recurse off of that as well. If none of the starting options actually work, then there are no solutions to the problem itself. The crux of backtracking is also that when you recurse, you only consider the solutions or guesses that you have already made.
You can also think about this as a graph search problem. Wikipedia provides an interesting way of generalizing the backtracking algorithm.
Note, in the following, P is essentially data that is being taken in and is related to the problem.
def bt(c):
if reject(P,c) then return
if accept(P,c) then output(P,c)
s ← first(P,c)
while s ≠ Λ do
bt(s)
s ← next(P,s)
So how does backtracking differ in runtime than the real brute force, just try every number in every open spot? Well let’s break down each individual runtime.
If we think about having a normal sudoku matrix, with some blank cells, and possible options for each cell (in this case, for normal sudoku it’s just 9), we can think about the brute force runtime being:
for our normal sudoku game. With some variations, there might be more than just nine possibilities for each cell.
Ok so, that’s exponential. Which is obviously not great. What about backtracking?
Before we make any claims, let’s think about the worst case for a second. In the worst case, backtracking could still fail and just revert to a normal bruteforce algorithm!! The concept of backtracking really hinges on the idea that we are able to guess a good starting value for our initial cell. But let’s think about it. Let’s say that we find our cell that we’re going to fill and the correct value for the cell is actually 9, but we’re going to go through and try 1, 2, 3, … 7, 8 all before getting to 9. For each one of those, we recurse on our guess and try all the possibilities.
So you can imagine in the very worst case, that we get really really unlucky and that backtracking still has to fully exhaust our search space. That being said, the expected runtime for our backtracking algorithm is going to be much better in reality. We are most likely going to find a good starting point and then solve the entire matrix, much more quickly than with brute force.
But still… I have to report the worst case runtime as:
I figured I would compute the runtime of a few sudoku’s. These are the ones that came installed in the directory. I just pulled them off this website. Mad props to them for all the free sudokus with the solutions.
Here are some of the runtimes. Note, I am just reporting the time it took to solve the matrix. I did this using python’s time
library. Specifically, this snippet of code:
t0 = time.time()
print("Attempting to solve sudoku from filename: {}".format(filename))
solved = solve_sudoku(matrix)
if solved == None:
print "There is no solution"
else:
print("Solved sudoku with filename: {}".format(filename))
t1 = time.time()
print("Time to solve sudoku: {}".format(t1-t0))
solution_dict[filename[7:10]] = solved
Here are the runtimes:
| Sudoku Name | User Time (sec) |
|---|---|
| sudoku_257.txt | 21.5058 |
| sudoku_258.txt | 3.15790 |
| sudoku_259.txt | 0.07309 |
| sudoku_260.txt | 2.63807 |
| sudoku_261.txt | 4.79477 |
| sudoku_262.txt | 1.11362 |
You can see that most of them were solved with ease, but sudoku_257.txt
the program really chomped on. I’m not totally sure why, but if I were to guess, the backtracking algorithm just didn’t work super great with this one, and it might have reverted to something similar to the brute force algorithm. Regardless, it’s cool to have these variations in the actual program.
I actually struggled a bit with writing the code. It took me awhile to figure out how to cover all my base cases. I realized that this is on Geeks for Geeks, or at least I’m pretty sure, but I wasn’t really about looking at their solution, and I coded mine up from scratch. It’s not the most elequent, but I’m pretty proud of it. I know it could be much prettier, but at the moment, I’m content. I’m sure there are some really nice solutions out there on the web.
Anyway, check out the program here!. It’s got some nice features, such as being able to read in a matrix from stdin, from a file, default, and cycle through a directory and check the inputs. Let me know if anyone has any improvements! The code isn’t fully optimized yet, just a solution, that works and that I’m happy and proud with.
Overall, it was a solid project to work on. Definitely awesome to pick up a new concept like backtracking, as this was my first taste of it in both academics and actual programming. I’m looking forward to learning more about it. As always, definitely feel free to comment or shoot me an email if there are any questions, or anything that I can do a lot better. Always looking to improve.
