As promised, I have returned with the second coding problem
Not much has changed for me in the last day. I’ve attempted a couple Minecraft speedruns, and suffered from some pretty significant allergies. Life is a pleasure as always.
Anyways, on to the problem
Problem 2:
Good morning! Here’s your coding interview problem for today. This problem was asked by Uber. Given an array of integers, return a new array such that each element at index i of the new array is the product of all the numbers in the original array except the one at i. For example, if our input was [1, 2, 3, 4, 5], the expected output would be [120, 60, 40, 30, 24]. If our input was [3, 2, 1], the expected output would be [2, 3, 6].
Follow-up: what if you can’t use division?
My solution:
Again we find ourselves with a fairly simple problem, although today’s was tagged as [Hard] hm… Anyway, we are being given an array and need to return an array which at each element contains the product of each of the elements from the input array excluding the item at the current index. Once again we want to split the problem into 3 pieces.
Input:
An array of integers we’ll call arr
Goal:
Return an array with the product of the entire input array, excluding the element at the current index.
Constraints:
Can we do this without division?
Time to write some code
Anytime I see a challenge constraint I immediately try to solve the problem including that approach first, but for the sake of explanation I will start with the easier version first. The first thing that comes to mind is to iterate through the list and then use nested iteration at each element to get the product. There are a couple key issues with the approach. The first is that this over complicates the problem, we need to use our heads here and not just charge at the problem with for-loops brandished. The second issue is that this algorithm would then have a time complexity of O(n^2) which, in my book, is much to large for this problem.
Let’s start with approaching this from a math perspective
What is the easiest way to get the product excluding a particular element? If we really want to simplify our work we can just multiply each of the elements and then
everytime we want to get the value we simply divide the product by the element in question. The implementation should look something like this:
First I’ll just define my array
const arr = [3, 2, 1]
Next I’ll define my product and division functions with arrow functions
// vvvvv Division vvvvv
const product = (lst) => { // define product function
let prod = 1 // our product variable
for (let num of lst) // loop through values in the array
prod *= num // scale product
return prod //return the product
}
const division = (lst) => { // define the division function
let output = [] //define an output array
const prod = product(lst) // get the total product by calling our previous function
for (let num of lst) // increment through values in the array
output.push(prod / num) // add product/element to output array
return output //return array
}
console.log(`With division: ${division(arr)}`) // output: 2,3,6
The product function will take in our array and multiply each of the elements to give us a total product. Division will divide the product by the element at the current index and add that value to the output array.
A little bit harder…
Now we want to try to do this without using division. I have not yet come up with a solution better than O(n^2), but I’ll keep it in the back of my mind and publish an
edit when I come up with one.
Let’s figure out how we are going to structure this answer… We need to write a function which will take an array and and index to ignore when multiplying the values in
the array. That doesn’t sound too hard, so let’s do it.
const multiply = (lst, index) => { //define a function which takes an array and an index to ignore
let prod = 1; //define a product value
for (let i in lst) { //loop through indexes
if (i === index) //if ignored index, don't multiply
continue //skip loop iteration
prod *= lst[i] //increase product
}
return prod //return product
}
Here we have a function which will loop through the array and anytime it is at the passed index it will simply skip that step and continue with
the process of multiplying the values. It will then return the product. Notice I made use of the continue
keyword here, much to the chagrin
of all my past CS professors, but they can’t take off style points here. HAHA! This could also have been accomplished by using an if statement or
even a ternary statement if you are really feeling feisty, but this is the implementation I chose. Anyway, we now just need a function which adds
each of these values to an output array, much like the first implementation.
const noDivision = (lst) => {
let output = [] //define an empty output array
for (let i in lst) //loop through indexes
output.push(multiply(lst, i)) //append the result of multiply()
return output //return our new array
}
console.log(`Answer without division: ${noDivision(arr)}`) // output: 2,3,6
And there we have it. A solution to the challenge portion of the problem, which returns the same values as the simpler implementation. I guess I’ll call this a succes if this is supposedly a [Hard] problem
So yeah… I’ll see you in the next one
Edit:
It has been brought to my attention that the challenge part of this question can be completed in O(n) by looping through the array twice. The first time from front to back, assigning the value before calculating the product, and then doing the same thing again from back to front. It should look something like this:
const arr = [3,2,1]
const firstPass = (lst) => {
let product = 1
let output = []
for(let num of lst){
output.push(product) // add product to array
product*=num // scale product
}
return output // return output
}
const secondPass = (lst) => {
let product = 1
for(let i = lst.length-1; i > -1; i--){ // loop through array backwards
lst[i]*=product // multiply current value by the product
product=arr[i] // scale the product
}
return lst //return outpur
}
console.log(secondPass(firstPass(arr))) // outputL 2,3,6
I can’t claim credit for this algorithm, as I did not come up with it on my own, but I said I would update this post if I found an O(n) solution, so here it is.
See ya in the next one…

In a not too distant dystopian future, Earth has been submerged in water. The battle for dry land has plunged the world into war, famine and financial chaos. The last vestiges of law in York attempt to restrain the pirate rebels from disrupting order.  You are equipped with just a floating barrel and a musket short of ammo. Whilst traveling ship to ship you begin forgoing morales for meals.
You have seen your share of woe - families butchered, elderly thrown into the waves, witnessed scurvy turn the strongest of men into food for the sharks. Meanwhile, the rich indulged a lavish life on land. Their navy spend their days keeping the outsiders out and their chosen few safe. But you survived... and now you want justice. You aim to unite the pirates, to join the tribes with the common motive of revenge. To provide a place for your children and family to live a life without pain, a life without worry - a life of peace.

In this section, you’ll have a chance to practice the concepts you’ve learned in the videos. First, review the core concepts covered that you’ll need to keep in mind. Then go through the exercises below.
Remember, these are for your own benefit. Feel free to skip them if you don’t find a particular exercise valuable or you get stuck for too long.
When working with an application that uses external packages, you need to
communicate what packages are required for it to run. We do this with a
requiements.txt
file, here is an example:
colorama
prompt_toolkit
Once you have a virtual environment active, you can install all the dependencies with this command:
(env) C:\> pip install -r requirements.txt
Virtual environments are key to having different versions of the same library coexisting on your computer. You create one as follows:
$ python3 –m venv venv
$ . venv/bin/activate
C:\> python –m venv venv
C:\> venv\scripts\activate
Pip is the tool you use on the command line to install and view external packages. Here are some examples:
$ pip list
$ pip install colorama
$ pip install -r requirements.txt
$ pip uninstall requests
Now it’s your turn. In this practice, go back to the tic tac toe game we created back in the chapter on problem solving. Alternatively, if you made it through Connect 4, you can work with that one instead. Your job will be to:
settings > project > project interpreter
.
colorama
as a
dependency.
pip
.colorama
to add colored output to your game.

Fans celebrate Stranger Things Day – the 36th anniversary of Will’s disappearance
The memes are running wild
Today is Stranger Things Day, marking the 36th anniversary of the disappearance of Will Byers, and fans are coming out in force.
Every year on November 6, fans across the internet share all manner of Stranger Things-related content to mark the special day.
As part of the celebrations for Stranger Things Day, Fortnite are bringing back their Chief Hopper and Demogorgon costumes from the game back, which were originally created in partnership with the premiere of the third season of Stranger Things earlier this year.
The crossovers don’t stop there, with SpongeBob SquarePants also getting in on the Stranger Things act.
Elsewhere, fans have been taking the opportunity to create all manner of memes around the show. “today is exactly 36 years old eleven met benny the first person in fact that made her smile,” one wrote.
Fans were also hoping that a release date would be shared for season 4 of Stranger Things to mark today’s events, but at the time of writing nothing has materialised.
Season 4 of the show was officially confirmed back in September along with the tagline: “we’re not in Hawkins anymore,” hinting that the story will take place in settings away from the original location.
In the past, Ross Duffer has said he thinks Stranger Things will be a four-season show, telling Variety, “We’re thinking it will be a four-season thing and then out.”
In response to the comments, the show’s executive producer Shawn Levy told Entertainment Weekly: “Hearts were heard breaking in Netflix headquarters when the Brothers made four seasons sound like an official end, and I was suddenly getting phone calls from our actors’ agents…the truth is we’re definitely going four seasons and there’s very much the possibility of a fifth. Beyond that, it becomes I think very unlikely.”

Stage Fright is a JavaScript powered presentation framework
Stage Fright takes inspiration from Flowtime.js and reveal.js
It's tiny, about 13KB minified and around 4KB gzipped
It supports fragments and comes with a nifty minimap that shows presentation progress
If there are fragments remaining on a slide, the slide in the minimap will be greyed out until all fragments are shown
This is the last fragment on the slide
It even supports Speaker Notes (press s
to start them up)
The markup is designed to be semantic
A vertical grouping of slides is a ._stage--group

Each slide is a section
inside the article, with a ._stage--content
class. Inside is the content wrapper, ._stage--content
. Notes can be added by including an aside
with the ._stage--notes
class as a sibling of the content

The popular image is of Johnny Appleseed spreading apple seeds randomly, everywhere he went. In fact, he planted nurseries rather than orchards, built fences around them to protect them from livestock, left the nurseries in the care of a neighbor who sold trees on shares, and returned every year or two to tend the nursery. His first nursery was planted on the bank of Brokenstraw Creek, south of Warren, Pennsylvania. Next, he seems to have moved to Venango County along the shore of French Creek,[8] but many of these nurseries were located in the Mohican area of north-central Ohio. This area included the towns of Mansfield, Lisbon, Ohio, Lucas, Perrysville, and Loudonville.
According to Harper’s New Monthly Magazine, toward the end of his career, he was present when an itinerant missionary was exhorting an open-air congregation in Mansfield, Ohio. The sermon was long and severe on the topic of extravagance, because the pioneers were buying such indulgences as calico and imported tea. “Where now is there a man who, like the primitive Christians, is traveling to heaven barefooted and clad in coarse raiment?” the preacher repeatedly asked until Johnny Appleseed, his endurance worn out, walked up to the preacher, put his bare foot on the stump that had served as a podium, and said, “Here’s your primitive Christian!” The flummoxed sermonizer dismissed the congregation.

You can edit in the browser before you save it as a PDF or after, using a PDF editor, it detects every field that you can edit in the browser, but it is less pretty to use a PDF editor.
Delete anything you don't want to be permanently on it, use CTRL+P and select save it as a PDF, save.
Depending on the browser, it will say save it as a PDF or print it as a PDF, either will save it as a PDF.
Delete anything you don't want to be permanently on it, use CTRL+P and select your printer, print.
Also, make sure that headers and footers are toggled off for printing.
1. Writing prompt/ideas for characters
2. Making a first level character and you want to have everything already input
3. DM's making new characters for their PC's to interact with and have them documented
4. Use it to merely copy your character onto paper with, if you need something to erase by hand
etc.
It should automatically adjust very well to any screen size.
The only thing I added outside of the PHB was 2 Cleric domains to balance it out statistically by the
builds.
There are three builds in here for clerics, dex, wis, and str-focused. Each has 3
domains inside of it that are possible.
I added
death and arcana to make it so all had 3 each, so it was statistically as likely to get any of
them.
Other than those two domains, everything in this generator is vanilla 5e.
The logical version builds a character that is cohesive together, based on your stats, if anything can be random in this version and still make sense, it is.
The COMPLETELY random version of the generator. Every element inside of this version is random.
You are able to choose from various options like race, class, background, and alignment to accommodate any specific game setting, but I would suggest using all random for a truly random experience.
After the stats and race are generated, the generator decides how to fill in the rest based on just
those two at the start.
It goes down a flowchart of possible classes based on the stats, and
picks the best one from the stats given, after racial
bonuses.
It shouldn't give you a class that doesn't fit a build, if a character doesn't have a clear
build for a class, it gets replaced.
After that it is really just more of the same logic, it
takes all the information given to it before the present
step and decides.
For example, if you have higher dexterity than strength, it'll give you a dextrous weapon if
your class starting equipment allows it.
There should be no errors, visual bugs, or technical errors, if there is contact me.
If you think
there is something I could do to make it better, feel free to contact me as well.
There is no
harm in making a suggestion.
Tweet me @LeviBlodgett or email me at<EMAIL_ADDRESS>Here are the facts:
Statistically, rolling gives you an average of the highest stats, with the
highest ceiling.
Standard array has the lowest risk and most consistency.
Point buy is the
best for the consistent optimization some players
seek.
(Although this generator has 65 combinations for in random order, so not all combinations are
necessarily optimal)
Stat total averages:
Rolling for stats total stats = 73.47 average
Standard array total
stats = 72 average
Point buy total stats = 72.32 average
If I'm rolling 4d6 and taking the highest 3, then the average is 12.24.
Total stat score = (12.245 * 6) = 73.47
If I'm taking the standard array, then the average is 12.
Total stat score = ((15 + 14 + 13 + 12 + 10 + 8)/6) = 72
If I'm taking point buy system, there are 65 possible combinations, and I calculated the average
below.
Total stat score = ((65 combinations added together)/65) = 72.32
((69 + 70(2) + 71(15) + 72(17) + 73(20) + 74(7) + 75(3)) / 65) = 72.3231

XGC(1) XGC(1) NAME xgc - X graphics demo SYNOPSIS xgc [-toolkitoption ...] DESCRIPTION The xgc program demonstrates various features of the X graphics primi‐ tives. In X, most of the details about the graphics to be generated are stored in a resource called a graphics context (GC). The xgc program provides a user interface for setting various GC components. Pressing the "Run" button causes these results to be displayed in the large draw‐ ing window on the right. Timing information is displayed in the window immediately below. The items in the upper left hand window work as follows: Function - specify the logical function with which primitives will drawn. The most usual setting is "set", i.e. simply to render pixels without regard to what has been drawn before. LineStyle - specify whether lines should be drawn solid in foreground, dashed in foreground or alternating foreground and background. CapStyle - specify the appearance of the ends of a line. JoinStyle - specify the appearance of joints between consecutive lines drawn within a single graphics primitive. FillStyle - specify whether lines, text and fill requests are solid, tiled with a pixmap or stippled. FillRule - specifies the rule used to fill polygons. The EvenOdd rule means that if areas overlap an odd number of times, they are not drawn. Winding rule means that overlapping areas are always filled, regardless of how many times they overlap. ArcMode - specifies the rule for filling of arcs. The boundary of the arc is either a Chord or two radii. planemask - specifies which planes of the drawing window are modified. By default, all planes are modified. dashlist - specifies a pattern to be used when drawing dashed lines. Line Width - specifies the width in pixels of lines to be drawn. Zero means to draw using the server's fastest algorithm with a line width of one pixel. Font - specifies the font to be used for text primitives. Foreground and Background - specify the pixel values to be applied when drawing primitives. The Foreground value is used as the pixel value for set bits in the source in all primitives. The Background value is used as the pixel value for unset bits in the source when using Copy Plane, drawing lines with LineStyle of DoubleDash and filling with FillStyle of OpaqueStippled. Percentage of Test - scrollbar permits specifying only a percentage of the test to be run. The number at the left indicates the current set‐ ting, which defaults to 100%. The window labeled "Test" permits choice of one a number of graphics primitive tests, including Points, Segments, Lines, Arcs and Filled Arcs, 8-bit Text and Image Text, Rectangles and Filled Rectangles, Image draws, as well as Copy Plane and Copy Area. The window to the right of this has buttons which permit record/playback of the primitives rendered. OPTIONS Xgc accepts all of the standard X Toolkit command line options. X DEFAULTS This program accepts the usual defaults for toolkit applications. ENVIRONMENT DISPLAY to get the default host and display number. XENVIRONMENT to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property. SEE ALSO X(7) BUGS This program isn't really finished yet, but it probably never will be, since it only demonstrates the original X11 core protocol rendering oper‐ ations, which few modern programs use anymore. AUTHORS Dan Schmidt, MIT X Version 11 xgc 1.0.3 XGC(1)

Linear regression (pynance.learn.linreg
)¶
-
pynance.learn.linreg.
predict
(features, model)[source]¶ Generate predictions from features and model.
New in version 0.5.0.
Parameters: features : ndarray
Features from which to generate predictions
model : ndarray
Regression model.
Returns: predicted : ndarray
Predictions generated from features using model.
-
pynance.learn.linreg.
run
(features, labels, regularization=0.0, constfeat=True)[source]¶ Run linear regression on the given data.
New in version 0.5.0.
If a regularization parameter is provided, this function is a simplification and specialization of ridge regression, as implemented in scikit-learn. Setting solver to ‘svd’ in
sklearn.linear_model.Ridge
and equating our regularization with their alpha will yield the same results.Parameters: features : ndarray
Features on which to run linear regression.
labels : ndarray
Labels for the given features. Multiple columns of labels are allowed.
regularization : float, optional
Regularization parameter. Defaults to 0.
constfeat : bool, optional
Whether or not the first column of features is the constant feature 1. If True, the first column will be excluded from regularization. Defaults to True.
Returns: model : ndarray
Regression model for the given data.


Provision of public infrastructure and services is heavily dependent on data – higher quality, timely data translates into more effective project design, implementation, and evaluation. Traditional methods for public sector data collection can be inefficient – for example, in the transport sector, travel times are often estimated using stopwatches, and common origin-destination pairs are derived through decennial household surveys.
Increasingly, the private sector is generating data that could be re-purposed to complement traditional public-sector data collection methods – for example, using fleet GPS data to estimate speeds or mobile operator data to determine travel patterns.
Rather than expend public resources collecting data that is already collected, the public sector should seek the comparative advantage of the private sector. In so doing, entirely new public good use cases could be discovered and implemented.
There is a persistent market failure in the international development community between the supply of private sector data and the demand for its use.
On the supply side, companies engaged in a range of businesses – e.g., ridesharing, social media, financial transactions, retail, shipping, mobile operators – generate data that can be repurposed for public good. However, since that “public good” may be in a sector outside the firm’s expertise, identifying an efficient public use would require intervention of a third party.
On the demand side, companies are approached daily with data requests from academics, NGOs, governments, and international organizations. For mid-size and small companies especially, the burden of responding to this disaggregated demand can be overwhelming – processing requests, understanding needs, signing bilateral legal agreements, assigning technical staff to respond to questions, ensuring data security – all of which would be outside the scope of the company’s core business objectives.
In practice, many companies are amenable to sharing data for public good, so long as: (a) the sharing would not compromise the company’s competitive advantage or the privacy of its customers; and (b) sharing would require no time or resources on their part.
Since international organizations have similar aims and government counterparts, they are coordinating data sharing agreements through a new International Consortium for Data Collaboratives.
Consortium negotiates data sharing agreement with data partner.
Framework agreement signed. All future data requests from Consortium members are made using a template, which is linked to the framework agreement and does not require additional signature.
Project and research proposals are solicited from Consortium staff through open process on the Data Collaboratives web platform. Partner may opt to review proposals.
Data securely and responsibly managed though Data Collaboratives IT architecture and formal data management procedures.
Partner kept updated on research and products through own branded web portal.
Derived data products and algorithms shared with data partner and, where appropriate, with the public and third parties.

INVITE YOU TO JOIN THEM AT THE CELEBRATION OF THEIR WEDDING
OUR LADY OF LOURDES CHURCH 2167 SPARROW STREET LOS ANGELES, CALIFORNIA


All javascript files located in scripts/source/ are changed , and now mochaUI works only with last mootools 1.4.5-full-nocompat distribution
Text editor CKEDITOR integration. For detail about CKEditor see http://cksource.com/
You should enabled PHP for this demo to work.
Check source file pages/CKEditor.php
Modals should now be created with new MUI.Modal() rather than new MUI.Window({type:'modal'}).
Added three new themes: Orange , igexao ,gureva and source Adobe Illustrator file: mochaUI-0.9.5-graphics.ai.
As they are developed their implementation may change a great deal,
though their file structure will probably remain basically the same.
Themes go in individual folders in the themes directory. Each theme needs a css folder, and images folder.
The CSS has been separated into style sheets that correspond with the various JavaScript files. Layout.css goes with Layout.js for instance. The style sheets that were in the css folder are now in themes/default/css/.
Each theme should have the same number of stylesheets and corresponding names. So if Theme 1 has a Layout.css, Themes 2 and 3 should also have a Layout.css.
You can change the themes directory path in Core.js.
Test IFRAME windows with three RSS feeds
The contentBgColor option has been removed from the Window Class, and the panelBackground option has been removed from the Panel Class. You should now use CSS for changing these colors. The addClass option in both the Window Class and Panel Class is helpful when styling some windows or panels differently than others.
As a matter of fact, all of the color options in Window.js are being deprecated. They should now be defined in the CSS.
If you set the background color of .mochaTitlebar, a gradient will be created from that value. The gradient will start with the value you gave plus 20% white, and end with the value you assigned plus 20% black. So the color in the middle of the gradient should be the color you defined.
If you want more control over the start and end colors of the gradient then set the background-image of .mochaTitlebar in the following way. Here we got a bit creative using a query string appended to a background image.
background: url(../images/spacer.gif?from=fafafa&to=e5e5e5);
"from" is the top color of the gradient. "to" is the bottom color of the gradient. Both must be hex values without the leading # sign.
To style some windows or panels differently than others use the addClass option. The example windows created from with JSON for instance have been given the class, "jsonExample". We can change their title bar color like so:
.jsonExample .mochaTitlebar { background-color: #6db6db; }
Split panels and windows are new as well, though they should be production ready. If you find any bugs with them let me know.
It is now considerably easier to fire window methods and some new methods have been added. It is possible I will shorten the chain further before the next release and make "retrieve('instance')" unnecessary.
// Returns the window's Class instance $('myWindow').retrieve('instance').close(); $('myWindow').retrieve('instance').minimize(); $('myWindow').retrieve('instance').maximize(); $('myWindow').retrieve('instance').restore(); $('myWindow').retrieve('instance').center(); $('myWindow').retrieve('instance').showSpinner(); $('myWindow').retrieve('instance').hideSpinner(); $('myWindow').retrieve('instance').hide(); $('myWindow').retrieve('instance').show(); $('myWindow').retrieve('instance').resize({width:500,height:300}); // Returns the window element $('myWindow').hide(); $('myWindow').show(); $('myWindow').shake();
Form in window shows basic form validation. Form was submited using Mootools Form.Request Ajax class.This class is not part of Mocha.
Please notice that you should update formWindow_content or mainPanel_pad with returned data.
Using Form.Request is highly recomended.
Is canvas based PIE chart. Script converts HTML table with class="pieChart" and two series, intoPIE Chart with results. Input HTML table:

Browser	 Value

Safari 	 180

Firefox	 210

IE 	 30

Opera 	 120

new MUI.Require({ css: ['scripts/canvas/css/piechart.css'], //images: [MUI.path + 'scripts/images/background.gif'], js: ['scripts/canvas/scripts/piechart.js'], onload: function(){ //new MyPlguins.MyGadget(arg); PieChart.implement(new Options); new PieChart(); } });Or if piechart.js is already loaded in  section
PieChart.implement(new Options); window.addEvent('domready', function(){ new PieChart(); });

"Two roads
diverged in a wood, and I—
I took the one less travelled by,
And that has made all the difference."
-- Robert Frost
Despite being written in the early part of the 20th century I often wonder if Robert Frost’s famous poem might actually have been about programming. Unless you’re writing a trivial piece of code every function has a happy path and a number of potential error paths. If you’re the optimistic kind of programmer you’ll likely take the well trodden path and focus on the happy outcome and hope that no awkward scenarios turn up. This path is exemplified in the original version of that classic first program which displays “hello, world!” on the console:
main()
{
printf("hello, world\n");
}
A standards conforming version of this classic C program requires the main function to be declared with an int return type to remind us that we need to inform the invoker of any problems, but luckily we get to remain optimistic as we can elide any return value (only for a function named main) and happily accept the default – 0. Consequently, irrespective of whether or not the printf statement actually works, we’re going to tell the caller that everything was hunky-dory.
The classic C version relies on a spot of “legal slight-of-hand” to allow you to put the program’s return value out of mind whereas C# and Java needed to find another way to let you ignore it so they allow you to declare main without a return type at all:
public class Program
{
public static void Main(...)
{
// print "Hello World!"
}
}
Of course these languages use exceptions internally to signal errors so it doesn’t matter, right? Well, earlier versions of Java would return 0 if an uncaught exception propagated through main so you can’t always rely on the language runtime to act in your best interests [1]. Even with .Net you can experience some very negative exit codes when things go south which will make a mockery of that tried-and-tested approach to batch-file error handling everyone grew up with:
IF ERRORLEVEL 1
Unless you know that Main can also return an exit code I don’t think it should be that surprising that people have resorted to silencing those pesky errors with an all-encompassing try/catch block:
public static void
Main(...)
{
try
{
// Lots of cool application logic.
}
catch
{
// Write message to stderr.
}
}
I wonder if this pattern is more common than even I’ve experienced as PowerShell has taken the unconventional approach of treating any output on the standard error stream as a sign that a process has failed in some way. This naturally causes a whole different class of errors on the other side of the fence that could be considered worse than “the cure”.
Back in the world of C and C++ we can be pro-active and acknowledge our opportunity to fail but are we still being overly optimistic by starting out by assuming success?
int main(int argv,
char **argv)
{
int result = EXIT_SUCCESS;
// Lots of cool application logic.
return result;
}
It’s generally accepted that small focused functions are preferable to long rambling ones but it’s still not that uncommon to need to write some non-trivial conditional logic. When that logic changes over time (in the absence of decent test coverage) what are the chances of a false positive? When it comes to handling error paths I’d posit that it’s categorically not zero.
The trouble with error paths are that they are frequently less travelled and therefore far less tested. A bug in handling errors where the flow of control is not correctly diverted can lead to other failures later on which are then harder to diagnose as you’ll be working on the assumption of some earlier step having completed successfully. In contrast, a false negative should cause the software to fail faster which may be easier to diagnose and fix. To wit, assume failure by default:
int result = EXIT_FAILURE;
The term “defensive programming” is one which was well intentioned, and requires an acknowledgement of failure to allow robust code to be written, but it has also been used to cover a multitude of sins – counter-intuitively making our lives harder, not easier. It stems from a time when development cycles were long, releases were infrequent, and patching was expensive. In a modern software delivery process Mean Time to Recovery is often valued more highly than Mean Time to Fail.
Another area where I find an overly optimistic viewpoint is with test frameworks. Take this simple test which does nothing:
[Test]
public void doing_nothing_is_better_than_being_busy_doing_nothing()
{
}
Plato once said that an empty vessel makes the loudest sound, and yet a test which makes no assertions is usually silent on the matter. Every test framework I’ve encountered makes the optimistic assumption that as long as your code doesn’t blow up then it’s correct, irrespective of whether or not you’ve even made any attempt to assert that the correct behaviour has occurred. This is awkward because forgetting to finish writing the test (it happens more often than you might think) is indistinguishable from a passing test.
When practising TDD the first step is to write a failing test. This is not some form of training wheels to help you get used to the process, it’s fundamental in helping you ensure that what you end up with is working code and test coverage for the future. Failing by default brings clarity around what it means to succeed, or in a modern agile parlance – what is the definition of “done”?
In those very rare cases where the outcome cannot be expressed as the absence of some specific operation occurring there are always the following constructs to make it clear to the reader that you didn’t just forget to finish writing the test:
Assert.Pass();
Assert.That(. . ., Throws.Nothing);
The few mocking frameworks which I’ve had the displeasure to use also have a similar misguided level of optimism when it comes to writing tests – they try really hard to hide dependencies and just make your code work, i.e. they adopt the classic “defensive programming” approach which I mentioned earlier. It’s misguided because exposing your dependencies to the reader is a key part of illustrating what the reader needs to know to understand what interactions the code might rely on. If this task is onerous then that’s probably a good sign you need to do some refactoring!
I’m being overly harsh on Hello World, it’s a program intended for educational purposes not a shining example of 100% error-free code (whatever that means). I’m sure a kitten dies every time an author writes “error handling elided for simplicity” but maybe that’s an unavoidable cost of trying to present a new concept in the simplest possible terms. However when it comes to matters of correctness perhaps we need to take the difficult path if we are going to provide the most benefit in the longer term.

G'day,
I have a dash that work fine when I'm logged in.
but when i access it without being logged in or someone without an account try's to view this the I get 0's on all the temp readings and 'Authentication not valid' on the graphs.
The dash is Public and published....Any ideas?
Thanks
Andy
Re: [Solved] Public dash not working
The feeds used by the dashboard also need to be public
Re: [Solved] Public dash not working
I never even saw the public bit in the feeds...
Thanks
Re: [Solved] Public dash not working
Realtime graphs show nothing (I can´t see, neither with mozilla firefox nor chrome):
http://emoncms.org/ewiandr&id=15314
As my realtime graphs, also:
http://emoncms.org/aicanduit
My feeds are public, my dash are public... anything else need to be public ?
When I´m logged in, I can see it OK.
Thanks in advance.

Re: [Solved] Public dash not working
Interesting...
If I log in, I can see my realtime graph and ewian realtime graph.
When I log out, I can´t see none...
Re: [Solved] Public dash not working
Any idea ?
Re: [Solved] Public dash not working
You may have got a better response if you had started your own thread instead of dropping in on someone else's. Especially as the title is marked 'Solved'.

Re: [Solved] Public dash not working
Sorry, meant no more confusing the forum with new threads with similar caption, even on issues that are not solved although the title says it.
Now I´ll open another thread.

Amazon To Open First Full-Service Grocery Store in 2020
by Stephanie MlotAmazon is opening a grocery store in Woodland Hills, Calif., next year.
The news comes after the company published four job openings for the future Los Angeles location.
“Join us as we launch Amazon’s first grocery store,” the posts said.
“We are passionate about creating a shopping experience that customers will love,” Amazon wrote. “If you are customer-obsessed, like learning new things, and want to contribute to end-to-end store operations for a new business, this is the place for you.”
Folks can apply now for a position as zone leader (full-time; starts at $16.90/hour), or grocery associate or food service associate (full-, part-, and flex-time; starts at £15.35/hour).
No further details were revealed.
The tech titan did tell CNET its new store will be different from subsidiary Whole Foods; and, unlike its high-tech Amazon Go shopping experience, the shop will use conventional checkouts.
There is no word, though, on what sort of selection or pricing to expect, nor whether Amazon plans to expand its grocery options into more cities.
In an email to Geek, an Amazon spokesperson provided no additional information.
The Wall Street Journal in March reported on plans to open a chain of Amazon grocery stores in Los Angeles, Chicago, and Philadelphia. At the time, the company had signed more than a dozen leases across LA, including Woodland Hills, Studio City, and Irvine.
Many of the proposed locations, the paper pointed out, are near urban cores and cater to middle-income consumers, stocking prepared foods and mainstream goodies like soda and Oreos.

| hoist {tidyr} | R Documentation |
hoist()
, unnest_longer()
, and unnest_wider()
provide tools for
rectangling, collapsing deeply nested lists into regular columns.
hoist()
allows you to selectively pull components of a list-column out
in to their own top-level columns, using the same syntax as purrr::pluck()
.
unnest_wider()
turns each element of a list-column into a column, and
unnest_longer()
turns each element of a list-column into a row.
unnest_auto()
picks between unnest_wider()
or unnest_longer()
based heuristics described below.
Learn more in vignette("rectangle")
.
hoist( .data, .col, ..., .remove = TRUE, .simplify = TRUE, .ptype = list(), .transform = list() ) unnest_longer( data, col, values_to = NULL, indices_to = NULL, indices_include = NULL, names_repair = "check_unique", simplify = TRUE, ptype = list(), transform = list() ) unnest_wider( data, col, names_sep = NULL, simplify = TRUE, names_repair = "check_unique", ptype = list(), transform = list() ) unnest_auto(data, col)
.data, data |

.remove |

.simplify, simplify |
If |
.ptype, ptype |
Optionally, a named list of prototypes declaring the desired output type of each component. Use this argument if you want to check each element has the types you expect when simplifying. |
.transform, transform |
Optionally, a named list of transformation functions applied to each component. Use this function if you want transform or parse individual elements as they are hoisted. |
values_to |
Name of column to store vector values. Defaults to |
indices_to |
A string giving the name of column which will contain the
inner names or position (if not named) of the values. Defaults to |
indices_include |
Add an index column? Defaults to |
names_repair |
Used to check that output data frame has valid names. Must be one of the following options:
See |

The three unnest()
functions differ in how they change the shape of the
output data frame:
unnest_wider()
preserves the rows, but changes the columns.
unnest_longer()
preserves the columns, but changes the rows
unnest()
can change both rows and columns.
These principles guide their behaviour when they are called with a
non-primary data type. For example, if you unnest_wider()
a list of data
frames, the number of rows must be preserved, so each column is turned into
a list column of length one. Or if you unnest_longer()
a list of data
frame, the number of columns must be preserved so it creates a packed
column. I'm not sure how if these behaviours are useful in practice, but
they are theoretically pleasing.
unnest_auto()
heuristicsunnest_auto()
inspects the inner names of the list-col:
If all elements are unnamed, it uses unnest_longer()
If all elements are named, and there's at least one name in
common acros all components, it uses unnest_wider()
Otherwise, it falls back to unnest_longer(indices_include = TRUE)
.

Launching Spark on YARN
Support for running on YARN (Hadoop NextGen) was added to Spark in version 0.6.0, and improved in 0.7.0 and 0.8.0.
Building a YARN-Enabled Assembly JAR
We need a consolidated Spark JAR (which bundles all the required dependencies) to run Spark jobs on a YARN cluster.
This can be built by setting the Hadoop version and SPARK_YARN
environment variable, as follows:
SPARK_HADOOP_VERSION=2.0.5-alpha SPARK_YARN=true sbt/sbt assembly
The assembled JAR will be something like this:
./assembly/target/scala-2.10/spark-assembly_0.9.0-incubating-hadoop2.0.5.jar
.
The build process now also supports new YARN versions (2.2.x). See below.
Preparations
- Building a YARN-enabled assembly (see above).
- The assembled jar can be installed into HDFS or used locally.
- Your application code must be packaged into a separate JAR file.
If you want to test out the YARN deployment mode, you can use the current Spark examples. A spark-examples_2.10-0.9.0-incubating
file can be generated by running sbt/sbt assembly
. NOTE: since the documentation you’re reading is for Spark version 0.9.0-incubating, we are assuming here that you have downloaded Spark 0.9.0-incubating or checked it out of source control. If you are using a different version of Spark, the version numbers in the jar generated by the sbt package command will obviously be different.
Configuration
Most of the configs are the same for Spark on YARN as other deploys. See the Configuration page for more information on those. These are configs that are specific to SPARK on YARN.
Environment variables:
SPARK_YARN_USER_ENV
, to add environment variables to the Spark processes launched on YARN. This can be a comma separated list of environment variables, e.g.SPARK_YARN_USER_ENV="JAVA_HOME=/jdk64,FOO=bar"
.
System Properties:
spark.yarn.applicationMaster.waitTries
, property to set the number of times the ApplicationMaster waits for the the spark master and then also the number of tries it waits for the Spark Context to be intialized. Default is 10.spark.yarn.submit.file.replication
, the HDFS replication level for the files uploaded into HDFS for the application. These include things like the spark jar, the app jar, and any distributed cache files/archives.spark.yarn.preserve.staging.files
, set to true to preserve the staged files(spark jar, app jar, distributed cache files) at the end of the job rather then delete them.spark.yarn.scheduler.heartbeat.interval-ms
, the interval in ms in which the Spark application master heartbeats into the YARN ResourceManager. Default is 5 seconds.spark.yarn.max.worker.failures
, the maximum number of worker failures before failing the application. Default is the number of workers requested times 2 with minimum of 3.
Launching Spark on YARN
Ensure that HADOOP_CONF_DIR or YARN_CONF_DIR points to the directory which contains the (client side) configuration files for the hadoop cluster. This would be used to connect to the cluster, write to the dfs and submit jobs to the resource manager.
There are two scheduler mode that can be used to launch spark application on YARN.
Launch spark application by YARN Client with yarn-standalone mode.
The command to launch the YARN Client is as follows:
SPARK_JAR=<SPARK_ASSEMBLY_JAR_FILE> ./bin/spark-class org.apache.spark.deploy.yarn.Client \
--jar <YOUR_APP_JAR_FILE> \
--class <APP_MAIN_CLASS> \
--args <APP_MAIN_ARGUMENTS> \
--num-workers <NUMBER_OF_WORKER_MACHINES> \
--master-class <ApplicationMaster_CLASS>
--master-memory <MEMORY_FOR_MASTER> \
--worker-memory <MEMORY_PER_WORKER> \
--worker-cores <CORES_PER_WORKER> \
--name <application_name> \
--queue <queue_name> \
--addJars <any_local_files_used_in_SparkContext.addJar> \
--files <files_for_distributed_cache> \
--archives <archives_for_distributed_cache>
For example:
# Build the Spark assembly JAR and the Spark examples JAR
$ SPARK_HADOOP_VERSION=2.0.5-alpha SPARK_YARN=true sbt/sbt assembly
# Configure logging
$ cp conf/log4j.properties.template conf/log4j.properties
# Submit Spark's ApplicationMaster to YARN's ResourceManager, and instruct Spark to run the SparkPi example
$ SPARK_JAR=./assembly/target/scala-2.10/spark-assembly-0.9.0-incubating-hadoop2.0.5-alpha.jar \
./bin/spark-class org.apache.spark.deploy.yarn.Client \
--jar examples/target/scala-2.10/spark-examples-assembly-0.9.0-incubating.jar \
--class org.apache.spark.examples.SparkPi \
--args yarn-standalone \
--num-workers 3 \
--master-memory 4g \
--worker-memory 2g \
--worker-cores 1
# Examine the output (replace $YARN_APP_ID in the following with the "application identifier" output by the previous command)
# (Note: YARN_APP_LOGS_DIR is usually /tmp/logs or $HADOOP_HOME/logs/userlogs depending on the Hadoop version.)
$ cat $YARN_APP_LOGS_DIR/$YARN_APP_ID/container*_000001/stdout
Pi is roughly 3.13794
The above starts a YARN Client programs which start the default Application Master. Then SparkPi will be run as a child thread of Application Master, YARN Client will periodically polls the Application Master for status updates and displays them in the console. The client will exit once your application has finished running.
With this mode, your application is actually run on the remote machine where the Application Master is run upon. Thus application that involve local interaction will not work well, e.g. spark-shell.
Launch spark application with yarn-client mode.
With yarn-client mode, the application will be launched locally. Just like running application or spark-shell on Local / Mesos / Standalone mode. The launch method is also the similar with them, just make sure that when you need to specify a master url, use “yarn-client” instead. And you also need to export the env value for SPARK_JAR and SPARK_YARN_APP_JAR
Configuration in yarn-client mode:
In order to tune worker core/number/memory etc. You need to export environment variables or add them to the spark configuration file (./conf/spark_env.sh). The following are the list of options.
SPARK_YARN_APP_JAR
, Path to your application’s JAR file (required)SPARK_WORKER_INSTANCES
, Number of workers to start (Default: 2)SPARK_WORKER_CORES
, Number of cores for the workers (Default: 1).SPARK_WORKER_MEMORY
, Memory per Worker (e.g. 1000M, 2G) (Default: 1G)SPARK_MASTER_MEMORY
, Memory for Master (e.g. 1000M, 2G) (Default: 512 Mb)SPARK_YARN_APP_NAME
, The name of your application (Default: Spark)SPARK_YARN_QUEUE
, The hadoop queue to use for allocation requests (Default: ‘default’)SPARK_YARN_DIST_FILES
, Comma separated list of files to be distributed with the job.SPARK_YARN_DIST_ARCHIVES
, Comma separated list of archives to be distributed with the job.
For example:
SPARK_JAR=./assembly/target/scala-2.10/spark-assembly-0.9.0-incubating-hadoop2.0.5-alpha.jar \

Building Spark for Hadoop/YARN 2.2.x
See Building Spark with Maven for instructions on how to build Spark using the Maven process.
Important Notes
- Before Hadoop 2.2, YARN does not support cores in container resource requests. Thus, when running against an earlier version, the numbers of cores given via command line arguments cannot be passed to YARN. Whether core requests are honored in scheduling decisions depends on which scheduler is in use and how it is configured.
- The local directories used for spark will be the local directories configured for YARN (Hadoop Yarn config yarn.nodemanager.local-dirs). If the user specifies spark.local.dir, it will be ignored.
- The –files and –archives options support specifying file names with the # similar to Hadoop. For example you can specify: –files localtest.txt#appSees.txt and this will upload the file you have locally named localtest.txt into HDFS but this will be linked to by the name appSees.txt and your application should use the name as appSees.txt to reference it when running on YARN.
- The –addJars option allows the SparkContext.addJar function to work if you are using it with local files. It does not need to be used if you are using it with HDFS, HTTP, HTTPS, or FTP files.


I am a product-driven software engineer, dedicated to crafting delightful user experiences and building seamlessly with my team. I strive for a light touch both in terms of aesthetics and clear, minimalist code, and am always eager to experiment with new technologies and different design patterns.
I have experience building across the full stack for web and mobile, including creating RESTful APIs, designing database schemas for structured and semi-structured data, and engineering responsive, progressive and accessible user interfaces.
Some of my favorite tools for accomplishing this include: HTML5, CSS3, SCSS, JavaScript (ES5/6), Node.js/Express, jQuery, React, Angular, Git and Webpack.
