Pew Research Center’s main website offers plenty in the way of polished reports, data visualizations and interactives. But there are also lots of methodological musings, puzzles and tangles that you would see if you could flip those picture-perfect research products over (metaphorically speaking).

We’re here to do that part for you.

Since we can’t loop you, our research friends, into our in-office chatter, we’ve created this channel as the next best thing. At Decoded, you’ll find blog posts about some paths taken and some narrowly avoided, including experiments that intrigued us but never saw the light of day. We’ll be talking about survey methods, of course, but also data science, data visualization and even news app development.

Feedback is majorly welcome — so leave your thoughts and questions in the comments or reach out to us via e-mail at info@pewresearch.org.

Thanks for joining us.

Solidity Fundamentals
By: Ferdi Kurt
Tags: Blockchain, Programming, Ethereum, Cryptocurrency, Smart Contracts

Integers

Solidity can manage integers signed/unsigned of various sizes (up to 256 bit) and also fixed point numbers for development (in the form of unfixed/fixed) which are not fully supported by the language yet and can be declared but can not be assigned to or from.

Watch out folks, we are going to talk about a very scary scenario which can cause huge harm.

When uint (unsigned integer) reaches its byte size, the next value added will return the first variable element.

note: 1 byte = 8 bits

Let’s say we have a uint8 , which is 8 bits. This means that the largest number we can store is 1111111 that is equal to 255 . Look at below example. If we execute increment function what will happen? This is called Overflow — it means that our new num_one is 0.
Journey into Data Science. An Introduction to Data

Let’s kick off with asking ourselves a question, What is Data?

→ In simpler terms, Data is a collection of objects and their attributes. Other names for a data object are record, point, vector, pattern, event, case, sample, observation, or entity.

Now, we must know what are Attributes?

→ It is a property or characteristic of an object. Example: Eye colour of a person. This is also known by other names such as variable, field, characteristic, dimension, feature etc.

However, to discuss and more precisely analyse the characteristics of objects, we assign numbers or symbols to them. To do this in a well-defined way, we need a measurement scale. Now, what the hell is a measurement scale?

→ Well, it is a rule (function) that associates a numerical or symbolic value(attribute values) with an attribute of an object. For instance, we classify someone as male or female.

Haiku Tale

Photo by Lina Trochez on Unsplash

Numb voice of silence

Like chime of thoughts in process ;

Hope born from ashes.

Magic which it floors

Like a fragrance from abode

Lantern’s light called — Hope.

The tale seems endless

If art lies in pursuance

Hope — Never gives up.

To the Life it breathes

Hope calms the storms of duress

Like ease in pitch-dark.

To hold onto Life

And rise with the wings of time

Garner — Hope — as guide.
Relationships are Fragile
By: Jocelyn Soriano
Tags: Relationships, Love, Advice, Inspiration, Relationship Advice

Relationships are fragile

The reason why we often hurt more the ones we love the most is because we do not realize this.

We take for granted the people who are always there for us and we are not as careful with their feelings as we are with people we hardly know.

A careless word. A negligent act. We often think we can get away with anything when we are with the people who love us.

While it is true that they will extend to us their utmost understanding, it is also true that they are but human beings after all.

They get hurt. And they get hurt the most by the people they love the most.

Relationships are fragile. It is far easier to protect it and to take care of it rather than to mend it when it is already broken into a million shattered parts.

Must we spend our precious time trying to gather the broken pieces?

Or should we rather spend our moments checking our tongues, saying words of encouragement and holding the hands of those we love the most?

In Memoriam: The Nintendo 3DS Family
By: Dylan Micheli
Tags: Gaming, Culture, Videogames, Games, Nintendo

The Nintendo 3DS was announced at E3 in 2010, and it wasn’t really too different from other DS consoles. Except for the 3D thing.

Games could play with a 3D effect similar to 3D Movies but without the requirement of 3D glasses. A slider on the side of the system allowed players to play with no three-dimensional effects, full 3D effects, or any level in-between. In fact, Nintendo used movie trailers on the E3 show floor to showcase the effect.

The overall form factor was basically unchanged though. Nintendo added a new “slide pad” above the d-pad and motion/gyro sensors, and buffed up the internal hardware to the point where gaming news outlets were comparing it to the full-fledged home consoles of the time. IGN called the design of the system as a “natural evolution of the Nintendo DSi system.”

Mario Kart 7 being played on the 3DS at E3 2011.

When launch came around, reviews were generally positive. There were some complaints about 3D, partially due to the low resolution of the screens, but reviews were good overall. But despite a positive reception from review outlets and record-breaking preorders, the system was still selling below Nintendo’s expectations.

The 3DS retailed at $250 USD, an fairly pricey amount for a handheld console. (The price of the original DS was only $150 at launch, for comparison.) Price cuts later in 2011 saw console sales increases jump up an incredible 260%. Nintendo ended up apologizing to early-adopters that paid the $250 and gave out a series of free Game Boy Advanced games to make up for it.

While the family didn’t sell to the insane amounts of the original DS or Gameboy and Gameboy Color families, the 3DS line still amounted for an impressive 75 million and 380 million units of hardware and software respectively over the course of its lifetime, with a wide variety of different console members.

5 of the 6 different 3DS family consoles (2DS XL not pictured).

One of my personal biggest complaints with the 3DS systems is the sheer amount of them. Aside from the 3DS, there’s the 3DS XL, 2DS, New 3DS, New 3DS XL, and the New 2DS XL. It’s gotta be one of the most complicated naming systems in recent memory, along with the Wii U debacle and the whole Xbox One X/Xbox Series X situation right now.

The introduction of the 2DS was one I found a bit weird, seeing as it removed the main gimmick of the console (the 3D) and also looked like a doorstop. The New 2DS XL though is probably one of the sleekest designs Nintendo has ever produced.

Why Black Votes Don’t Matter in 2020
By: Greg Frankson
Tags: Elections, Politics, Equality, Government, Race

Former Vice-President Joe Biden is very popular with African-American voters in the Democratic Party’s presidential primary. A recent Washington Post-Ipsos poll put Biden’s support at 48% with this key voting constituency.

So what?

The voting preferences of Black people aren’t the problem in Trump’s America. They know he’s a raging racist. They’ve known it since the time of the Central Park Five if they weren’t aware of it before then as one of his unfortunate tenants as far back as the 1970s. Trump’s infamous comments after a white supremacist killed an anti-racism protestor in Charlottesville in 2017 just exposed in an undeniable way what Black people knew all along.

African-Americans proved their belief in Trump’s unfitness for office when they voted overwhelmingly against him on Election Day in 2016. A CNN exit poll found that 89% of African-American voters cast ballots for Democratic nominee Hillary Clinton, compared to 8% for Trump, the standard-bearer for the Republican Party.

After watching him govern for three years, their opinion of Trump’s fit as president hasn’t changed. The WP-Ipsos poll found that 93% of African-Americans prefer any of the Democratic candidates over the president, with 73% saying they were certain they’d cast a ballot on Election Day 2020.

They want Trump voted out of office. Stat.
Getting PAX to You Faster — Introducing Auto-Transfers and Faster Processing
By: David Wells
Tags: Blockchain, Paxos, Paxos Standard, Cryptocurrency

Today we’re excited to announce a new feature on Paxos called Auto-Transfers. This makes it easier and faster to get PAX. When you’re able to get your PAX faster, you can then use it faster. At Paxos, we believe money should move at the speed of the internet. The features we’re building into the Paxos Platform reduce friction and help create a more global economy for our customers.

It’s easy to get started with Auto-Transfers: Once you’re logged in to your Paxos account, designate an ethereum address where you’d like to automatically receive PAX. Then, every time you wire USD to your Paxos account, we’ll instantly convert it to PAX and send it to your designated address.

This feature is really useful if you often deposit USD and transfer it as PAX to the same address again and again. This functionality will save you from repetitive action and get you PAX faster. Take a read through our User Guide to learn how to enable this feature.

There’s more too — we’re also speeding up how quickly we can process your PAX requests. Before, we had windows of time each day when we would process requests for PAX. Soon, we’ll be able to send PAX within minutes for requests below a certain USD threshold. Requests above that threshold may require compliance checks.

We’re constantly working to improve the Paxos Platform. You can expect more updates to our product in the days and months to come.

A Personalised Recommender from the BBC
By: Matt Crooks
Tags: Data Science, Recommendation System, Tf Idf, Recommender Systems

The BBC produces fantastic content that appeals to a mass audience such as Killing Eve and Bodyguard on BBC iPlayer, the Danger Mouse games for CBBC, and Match of the Day on the BBC Sport, to name a few. While it’s great that we can produce content that is enjoyed by so many different people it does create data science challenges around understanding the personalities and preferences of individuals. Episode 1 of Killing Eve, for example, attracted a whopping 26% of the TV audience during first transmission.

Term frequency-inverse document frequency (tf-idf) is a metric most associated with text analysis and, in particular, as a rudimentary search engine. It assigns a weight to each text document that tells us how relevant each one is to a particular search term. The success of tf-idf is largely down to the inverse document frequency part that penalises popular words in the search term. Common words such as “the” carry far less information than more niche words like “BBC”. This is how tf-idf differs from simply counting the occurrences of the search terms in each document.

Here at the BBC, we’re using tf-idf for entirely different applications: recommender systems.

By analysing how our audience interacts with our content we can infer similarity between different TV shows on BBC iPlayer, or articles on BBC News. This allows us to make more relevant recommendations and improve the experience that we offer. In terms of content association, our top hitters that have mass appeal reveal less information about a user’s specific interests. Hence, tf-idf allows us to make recommendations that are relevant on an individual user basis rather than just serving up our top content in all recommendations.

In the next post in this series I will discuss how, with the addition of a network graph community detection algorithm, we can use tf-idf to identify topics or genres of content that are defined by user behaviours. This allows us to enrich our metadata, improve recommendations and audience segmentations.
Peach Mango Smoothie Recipe
By: Crystal Hunt
Tags: Food, Smoothies, Recipe

Peaches are in season right now, and my efforts to get some dehydrated and put away for the winter are being hampered by the fact that they taste AMAZING fresh and I want to eat them all up, not dehydrate them! I compromised with the last case I bough. One third into the freezer, one third into the dehydrator, and one third into our mouths 🙂

I like to start off most mornings with a smoothie of fresh and/or frozen ingredients, and this morning’s concoction was good enough to share.

Ingredients

1 fresh ripe peach (or 1/2 to 3/4 cup frozen peach chunks)

1/2 cup plain greek yogurt, or coconut yogurt or your favourite yogurt alternative

1/2 cup frozen mangos

2–3 tbsp hemp hearts

1 cup chilled ginger lemon herbal tea (or whatever other flavour you want)

dash of vanilla (I use plain yogurt, so the vanilla is good for sweet and flavour — if you use vanilla yogurt then go ahead and skip the vanilla)

optional — if your mangos or peaches aren’t frozen you might want to throw in a few ice cubes to get that super chilly, slushy effect

Equipment

vitamix or other food processor

The Process

STEP 1: Well, there’s really only one actual step to this. Throw everything in the blender and blend it all up until it’s smooth and creamy.

STEP 2: Put it into your stomach, via a glass or your favourite drinking jar!
Scraping Tweets by Location in Python using snscrape
By: Scott Tomlins
Tags: Data Science, Scraping, Twitter, Pandas, Web Scraping

Scraping by Location

When filtering by location there are two options: you can use the near:city tag alongside within:radius or geocode:lat,long,radius . After extensive research I can confirm they yield identical results when used correctly (or should I say, as Twitter interprets them).

As an example, say you wanted to find all tweets about pizza in Los Angeles. This can be achieved using the following code:

Instead of using the city’s name you can use its coordinates:

To compare the results we can use an inner merge on the two DataFrames:

Which returns 50 , i.e. they both contain the exact same rows.

What exactly is this location?

There are two ways to get a location from Twitter; a geo-tag from a specific tweet, or a user’s location as part of their profile. According to Twitter, only 1–2% of tweets are geo-tagged hence it isn’t a great metric to be using; on the other hand a significant amount of users have a location in their profile, but they can enter whatever they want. Some are nice to people like us and will write ‘London, England’ or similar, while others are less useful, putting things like ‘My Parents Basement’.

All the documentation I could find indicated using a location as part of the search would only find geo-tagged tweets, however this isn’t the case. From my investigations I have discovered Twitter have some algorithms working as part of their advanced search that can interpret where a user’s location is from their profile, and assumes all of their tweets come from there. This means when you search for tweets using coordinates or a city name, the search returns tweets that are geo-tagged from that location, or that were tweeted by users with that location (or somewhere close-by) in their profile.

Photo by Lucas Davies on Unsplash

As an example, when I searched for tweets near:"London" I managed to find examples of both:

The first tweet is geo-tagged, and the user does not have a location as part of the profile, i.e. the tweet was found because of its geo-tag. The second tweet is not geo-tagged, and was found because the user has their location in their profile.

The Cost of Love: Appraising the Twelve Days of Christmas
By: Kyla Scanlon
Tags: Economics, Math, Data Science, Tech, Technology

How to get into the holiday spirit? Do some math!

The Twelve Days of Christmas is a Christmas carol that lists out items that a (supposed) lover is purchasing for his love.

The earliest version of the song appeared in a kid’s book titled, Mirth With-out Mischief in 1780. However, the version that we are most familiar with was established by Frederic Austin in 1909.

The gifts are as follows:

One partridge in a pear tree

Two Turtle doves

Three French hens

Four calling birds

Five gold rings

Six geese a-laying

Seven swans a-swimming

Eight maids a-milking

Nine ladies dancing

Ten lords a-leaping

Eleven pipers piping

Twelve drummers drumming

PNC Wealth Management puts together a Christmas Price Index, but I wanted to test their methodology. I always wanted to see what it would have costed when the song was first created (which is easier said than done).

I am going to alternate between £ and $ (due to some of the data sources) but the final analysis will compare the two time periods in $.

Key Assumptions:

I assumed the 1800s were pretty consistent price-wise across the years, so there isn’t a set year that I pulled all the below prices from. However, everything is adjusted to 1875 prices.

I estimated the labor costs to be for 24 hours

I used the History of British Birds (Volume I and Volume II) to get the prices for the birds, but William Yarrell didn’t list out all the birds, so I made some educated guesses

I used Measuring Worth for all my currency conversions and purchasing power estimates.

Also, a note on the money: “Colonists counted their money by the English system of pounds, shillings, and pence — twelve pence (pennies) per shilling, and twenty shillings per pound.”

Source: History of British Birds, Vol 1 and Vol 2

Another note: This was harder than I thought. There might be errors in my bird classifications or my pricing estimates. Sorry in advance, if so!

So behold: the true cost of the 12 Days of Christmas.

June Edition: Bias in the machine

Fairness, bias, and interpretability in artificial intelligence and machine learning models

Photo by Ryoji Iwata on Unsplash

As machine learning applications become more widespread, there has been great interest in implementing algorithms to transform usual business processes to realize efficiencies. From loan approvals to judicial sentencing, consumers and citizens face the reality of a black-box model as the final arbiter behind some of the most important decisions and events in our lives. It has become more critical than ever to understand the question of bias and fairness in the models we create and ensure that they don’t create unintended and/or discriminatory outcomes.

Machine learning bias is not well-addressed, or even well-understood, in data science. But researchers and other practitioners have taken steps to highlight the importance of mitigating sources of bias and finding solutions to prevent harms resulting from them. The following articles are a selection of our best stories on bias, fairness, and interpretability. We hope that they enrich your understanding and act as a resource of best practices when you encounter biases in your own models.

The Wonderfully Delicious Sass of Dill Pickle Soup

The Wonderfully Delicious Sass of Dill Pickle Soup

Quick! Dig out the dill pickle jar hiding in the back of your fridge.

I confess — I am an obsessed lover of pickles. And so years ago when I stumbled upon a restaurant that was famous for their dill pickle soup — I was all in.

The unusual soup was creamy, slightly sour, and had a wonderful texture. I couldn’t wait to try making it at home. Because as much as I loved this soup — they charged $10 for an itty bitty bowl and I’m the kind of soup lover who needs a bowl the size of my head. Maybe you know how I feel.

And so the experimentation began. I’ve tried many varieties and brands and discovered I like a firmer pickle vs a mushy one. And I always make sure to buy a jar of snappy, garlic pickles made in the USA, or Canada or Poland. (The Polish really are rockstars with pickles. So make sure to read the back of the jar.)

When I made my first batch of dill pickle soup and offered it to a friend who claimed to love pickles— she acted strangely. She was being a fickle pickle friend.

Like I had offered her eye of newt from my cauldron.

Her eyebrows went up and she took the most ridiculously small amount on her spoon. I know I rolled my eyes at her.

And then her face lit up and I said, “Told you!” and I offered her a bowl the size of her head too. So if you’re having doubt about eating pickle soup — don’t worry — there’s hope for you yet.

INC4 Partners With bloXroute Labs to Boost Its ETH Mining and Blockchain Engineering Business bloXroute Team Follow Nov 5 · 3 min read

By bloXroute Labs Business Development Shen Chen

The bloXroute Labs team is pleased to announce a partnership with INC4 to collaborate on reducing the ETH uncle rate of INC4’s mining pool, MinerAll, and promoting our BDN (Blockchain Distribution Network) service to INC4’s clients.

INC4 is a privately held development team and blockchain engineering service provider based in Europe. Minerall is their leading on-the-market ETH mining solution. Since mid August, INC4 has deployed the bloXroute BDN Gateway on Minerall’s ETH mining nodes and has already seen an improvement in its ETH block and transaction propagation.

This is a result of the BDN’s advanced network performance features, such as data compression, fast data streaming, and dynamic route optimization. It is also attributed to the network effects collectively created by 13 other ETH mining pools and numerous ETH service providers employing the BDN.

In addition to operating the leading mining pool MinerAll, INC4 is a powerhouse in ETH application development, including full-stack and custom software development. Using the BDN, they can now leverage its fast data propagation to increase performance and differentiation for their clients’ products.

The CEO of INC4 Igor stadnyk commented on the partnership, “It is great to witness something like the emergence of the cryptocurrency market and see that it is constantly evolving with the help of teams like bloXroute Labs. Their BDN illustrates the way miners communicate: Mutual assistance is key. As ETH technologies continue to develop — bloXroute Labs is satisfying the demand of miners.”

Co-Founder and COO of bloXroute Labs Eyal Markovich added, “bloXroute’s BDN is helping both big and small ETH miners by leveling the playing field and eliminating P2P network bottlenecks. The BDN is also enabling all kinds of ETH application developers, users, and ETH traders to improve their performance. With a broad portfolio ranging from ETH mining to application development, INC4 can take full advantage of the BDN. We really appreciate the partnership and look forward to working with INC4 to boost their business.”

About INC4:

Take advantage of raw strings in Swift 5
By: Ashish Kakkad
Tags: Swift Language, iOS, Swift Programming, Swift, iOS App Development

Swift 5 comes with enhancement in string literals delimiters to support Raw Text.

Let’s go with examples

Use of # delimiter

We can use # delimiter with start and end of the strings to use less escape sequences.

fileprivate func useOfHashDelimiter() {

let stringSwift4 = "This is \"Swift 4.x\"."

print(stringSwift4)



let stringSwift5 = #"This is "Swift 5.x"."#

print(stringSwift5)

}

Output:

This is “Swift 4.x”.

This is “Swift 5.x”.

Use of variables with # delimiter

We can use variable with string like \#(variableName)

fileprivate func useOfVariableWithString() {

var intSwift = 4

let stringSwift4 = "This is \"Swift \(intSwift).x\" with variable."

print(stringSwift4)



intSwift = 5

let stringSwift5 = #"This is "Swift \#(intSwift).x" with variable."#

print(stringSwift5)

}

Output:

This is “Swift 4.x” with variable.

This is “Swift 5.x” with variable.

Multiline String with # delimiter

We can use # delimiter in multiline strings too.

fileprivate func withMultilineString() {

let intSwift = 5

let multiline = #"""

This is

Swift \#(intSwift).

"""#

print(multiline)

}

Output:

This is

Swift 5.

Conclusion

Swift is getting more stable day by day!

How Will Hunter Biden’s Legal Troubles Affect Joe Biden’s Presidency?
By: Caren White
Tags: Politics, Government, Biden, Attorney General, Department Of Justice

So how does this affect his father’s cabinet?

The most important thing to bear in mind is that no evidence has been found that Joe Biden had anything to do with his son’s business activities. Yes, Hunter traded on his father’s name and position as Vice President in his dealings with foreign entities but that does not mean that his father was in any way involved.

Joe Biden has been filling his cabinet with people that he has known and worked with for years. The concern is that if he chooses for attorney general someone that is close to him, it could be perceived as a conflict of interest.

After all, wouldn’t you be tempted to go easy on the son of an old friend? Especially a friend who is president and has appointed you to one of the most prestigious jobs in his administration?

Some Republicans have gone so far as to suggest that a Special Counsel be appointed to head the investigation into Biden’s son to ensure there will be no favoritism.

With or without a Special Counsel, if the investigation does not end up with criminal charges and Hunter is declared innocent of any wrongdoing, in the eyes of many people, the DOJ will have a lot of explaining to do about how it arrived at that conclusion.

We have become so accustomed to Trump directing the DOJ, that it will be difficult to switch gears to an administration that respects the independence of the Attorney General and Justice Department.

Many people will remain suspicious that Biden had something to do with dropping the investigation into his son.

Starting off his presidency with his son under investigation shouldn’t affect how Biden functions as president. Previous presidents have had relatives run afoul of the law with no significant impact on those presidents’ abilities to do their jobs.

As long as Biden makes good on his promise of independence for the DOJ, the investigation into his son should have no effect on his presidency.
“The Scrum Values got me fired”
By: Willem-Jan Ageling
Tags: Agile, Scrum, Scrum Master, Areyouserious, Leadership

The organisation — including sufficient management layers — voice that they embrace Scrum in all it’s aspects. This organisation puts a lot of time, money and energy into making everyone ready for this.

This includes:

Expensive Scrum training for all involved.

The teams got encouraged to do Scrum as it should be done.

The organisation seeks publicity to show how they are front-runners on Agile and Scrum. Many organisations do this. You want to be one of the cool kids, right?

One of the topics that is embraced is “Scrum Values”. This means openness, respect, focus, courage and commitment.

“When the values of commitment, courage, focus, openness and respect are embodied and lived by the Scrum Team, the Scrum pillars of transparency, inspection, and adaptation come to life and build trust for everyone.” — Scrum Guide 2017

It should be obvious — the Scrum Values are an integral part of Scrum — but I find that I need to state this specifically.

It all looks beautiful. You would say that everyone is on the same page.

But reality bites. People that show courage and bring forward impediments caused by a top-down management style — impeding self-organisation — are clearly told to stop doing this. Some managers don’t wish to change their behavior and the people working in “their” Scrum Teams are told to “stop calling out”.

One Scrum Master decided to be courageous, to continue to address behaviour that wasn’t in line with what the company agreed on and also wasn’t in line with Scrum. He genuinely believed that the company was serious about Scrum. Within a couple of weeks he was fired.

Way to go Scrum Values! Way to go courage!

What is the lesson here?

Here we are. First people are educated and convinced that the company is going to embrace Scrum. All signs appeared to be on ‘green’. Everything pointed towards a genuine adoption of Scrum. But in the end it was just lip service, at least from the person that fired the Scrum Master. Scrum was for the Scrum Teams only. Any obvious impact on the stakeholders was deemed unacceptable. Management could excuse themselves from everything without being corrected.

Did the Scrum Master forget to reach out to people on the same page, including management? Probably! But it remains remarkable that some could simply ignore company wide agreements.

This is not how it works. If a company embraces Scrum everyone in the company is impacted. It is pivotal that everyone has an understanding what it is and what it is about. Scrum is not a set of practices only. The Scrum Values are an integral part of the framework. Without it Scrum simply DOESN’T WORK!

Here the Scrum Master normally steps in to be:

“Leading and coaching the organization in its Scrum adoption;” — SG

And

“Helping employees and stakeholders understand and enact Scrum and empirical product development;” — SG

But that doesn’t work in the end if the Scrum Teams have to figure it out without support.
September Smiles

September smiles down on me

as rains return, heat slowly subsides.

Once more able to wear clothes, not feeling

like I might expire, returning to knitting, cosy for winter.

September is a time for bees,

harvesting excess honey, breakfast treats

meeting their health needs, check for stores,

planning the busyness of spring and new brood coming.

September is a time for clearing

stripping the old food plants from soil,

planting new winter crops, our favourites,

bright stems of leafy chard, deep green kale curlies.

September is a time for swimming,

maintaining routines in slowly chilling seas.

water smooth as silk, cool sliding against our skin,

at dusk or morning, wild waves coming, laughing crazy free.

September is a time for walking

far through the forests and across the downs

that surround our home, wild yet small, an islands

diminutive offerings compared to vast wilderness.

September is a time for friends

for sharing simple meals and harvesting

or crafting in company, activity, chatting, laughing

stories of summer adventures taken further afield.

September is a time for colours,

slowly changing from green to flames

with smoking fallen wood fires beneath trees,

shared toasting twigs for sausage and marshmallow.
If You Forget Me — Poem by Pablo Neruda
By: Trev Gibb
Tags: Poetry, Love

I want you to know

one thing.

You know how this is:

if I look

at the crystal moon, at the red branch

of the slow autumn at my window,

if I touch

near the fire

the impalpable ash

or the wrinkled body of the log,

everything carries me to you,

as if everything that exists,

aromas, light, metals,

were little boats

that sail

toward those isles of yours that wait for me.

Well, now,

if little by little you stop loving me

I shall stop loving you little by little.

If suddenly

you forget me

do not look for me,

for I shall already have forgotten you.

If you think it long and mad,

the wind of banners

that passes through my life,

and you decide

to leave me at the shore

of the heart where I have roots,

remember

that on that day,

at that hour,

I shall lift my arms

and my roots will set off

to seek another land.

But

if each day,

each hour,

you feel that you are destined for me

with implacable sweetness,

if each day a flower

climbs up to your lips to seek me,

ah my love, ah my own,

in me all that fire is repeated,

in me nothing is extinguished or forgotten,

my love feeds on your love, beloved,

and as long as you live it will be in your arms

without leaving mine.
28. Taste

Imbued with the flavor of a thousand African suns

Nurtured by the delicate hands of African daughters

Daughters of the soil;

Cooling as rain showers on a summer breeze

Refreshing as the dew on a thousand blades of grass

Grass like a duvet spread over rolling hills;

The taste of work

Sweet sweat of the brow

Of Passionate devotion and toil;

A taste of the hills in the city

Of rolling plains and grassy hills

Of sun shiny days and rainy nights;

Intense as the sweeping rivers

As gentle streams gleaming

Feeding the landscape;

The taste of commitment

Of journeys

Of people;

The taste of vision

Of connection

Of friendships;

The taste of satisfaction

Of diversity

In a glass of unity;

The taste of the African Mango.
