A frog at the window
By: A.C. Flory
Tags: Frogs, Australia, Bushfire, Warrandyte

The ledge of my kitchen window is over a metre off the floor of the deck which is, itself, close to two metres off the ground. Yet despite these giddying heights, there was a small frog on the ledge last night, looking in as I looked out:

A frog at the window, looking in

Apologies for the terrible photo. I’m a notoriously bad photographer at the best of times, and I had to blow this photo up quite a bit to make my little friend visible, so the quality plummeted. For those who are interested, my froggy friend is about two inches long from nose to tail and a grey colour with a slight greenish tinge.

As I have a pond near the house, I’m used to hearing frogs serenading each other at night:

The pond in the back ‘yard’ during the lush time of the year

I’m also used to finding them hidden in moist pockets under rocks, but I see them only rarely and never at my window.

After taking a few photos to prove that I wasn’t going mad, I went out and attempted to rescue Sir Frog, but said amphibian would have put Spider Man to shame. The suction pads on his fingers and toes allowed him to jump long distances and stick like glue when he landed.

Clearly those suction cups are how Sir Frog managed to climb up to the deck and from there to the window ledge, but I’m still baffled as to his motivation. Why leave the nice, moist environs of the pond to climb the dry slopes of Mount Everest?

The only explanation that makes even the slightest amount of sense is that Sir Frog came in search of a new, moist habitat in my plant pots. I’ve been growing heaps of tomatoes this summer, and tomatoes require lots of water so…

Far fetched? Perhaps, but most of Melbourne has been in the grip of a long dry spell since the start of February and everything has dried out:

Gum leaves carpeting the ground in Warrandyte

I took this photo about two weeks ago to show how many gum leaves are covering the ground. I raked up that knee high pile from just the steps and the small cleared area shown in the photo.

The whole block is covered with gum leaves shed since the beginning of summer. I know because I mowed everywhere as part of my pre-fire season clean up. Now look at it. Deciduous trees shed their leaves at the end of autumn. Eucalypts shed them during the summer. Low maintenance? Hardly.

The most recent photo shows how dry the soil has become:

Greywater vs no greywater

Areas trafficked by the alpacas are now so dry the earth has turned to powdery dust. You can see the contrast between the area that hasn’t received any grey water and the area that has. In the moist soil, grass and weeds are struggling to come back to life again. In the dry area there is nothing. Perhaps this is why Sir Frog came looking for a new home.

Speaking of Sir Frog, I did manage to rescue him in the end. I put him out in the garden and can only hope that he survives until we get some real rain. In Warrandyte, we’ve had only a millimetre or two since the start of February. It was barely enough to lay the dust. If you think fire season is over, think again.

Midnight Harbour. Sai Kung, Hong Kong

Fragmentation

of our lives.

Same city,

different time zone.

Every good night to me,

I am a woman of philosophy.

Sentiment,

A flaw in the system,

The way,

you see through your brown liquid,

is my way I see through my translucent smoke.

Dimensions frozen,

physics no longer effective.

That night at your place,

over jazz music

I saw you,

looking straight at me,

piercing through my soul.

I knew,

but I never speak of it.

We are pretty much the same,

despite our preferences.

Power BI Modelling — Using a Multi-Fact Model
By: Peter Hui
Tags: Technology, Data Modeling, Data Science, Power Bi, Data Visualization

You know you need a multi- fact table model when…you have a similar but different type of facts

As an example, you may have one table that deals with allocations of resources while another is expenditures. You may have different accounts; one is savings account and the other is a different account. You may have a budget table and you also have an expenses table.

These tables contain similar facts, they both deal with money, but the tracking is different. One table contains columns that are only relevant to budgeting while the other expenses. Also, the budget table aggregates at a monthly level, while the expenses table aggregates at a daily level.

Sometimes you may not be so lucky, sometimes you may get a fact table that is somehow flattened into one, like the one below, and you will soon see some issues with it.

Image by author

It’s hard to navigate the table like this, in scrolling through, you may think that the monthly budget may be the daily budget since there are different levels reflected in this table. The monthly budget is by month and the other by days. Too good to be an example? No, this is a real example I’ve seen.

There is a column that only pertains to the budget table (Donor_Name) and it has no relevance to the expenses. This can become a major problem if new columns need to be added. How about the donor’s dimensions? Perhaps we want to add in the donor’s address and time of donation? These fields, since they pertain to the budget part of this table, will need to have new columns. Adding columns can get out of hand quickly if this fact table is not separated properly.

You know you need a multi-fact table model when…when you have fact tables that naturally fit into an existing model

You can see, however, that some of the columns in this table naturally fit into the dimensions in the data model. It has the necessary dates and region. (The themes are existing)

Image by author

If I want to compare the budget and expenses by regions, the common dimensions (Date and Regions) should be existing in both fact tables.

You know you need a multi-fact table model when… when the fact tables need to be aggregated for comparison

Finally, the reason why you have to separate this fact table is for comparison purposes. We know having one big fact table is confusing, however, we will still need to make aggregated comparisons using it.

Something like this below very basic, but it’s only possible if you have a star schema already set up.

Image by author

To get to a comparison table like will require us to split up the fact table into two and make the relevant joins from there.

Day 541 — Fungi — Haibun Journey Beauty Each Day

Today’s beauty is a giant mushroom in my back yard. I noticed it a week ago. It was about three inches across and was a velvety dark rust with a very thick stem. Over the past week it has gotten large and larger. I have never seen one mushroom last so long in my yard. It’s fun to watch it, but too bad it’s not a portabello mushroom.

Sunlight on the Ocean
By: D Abboh
Tags: Poetry, Heartbreak, Prose, Life, Dreams

Our Eden blooms, against a backdrop of sunlight on the Ocean and the bluest sky. Even the boldest full Moon would think twice — then at least once more, before daring to disrupt this horizon. We are fully ensconced in our bliss, stretching out on an empty sun kissed beach hand in hand. We close our eyes and face the sun, all lit up — we greet the suns dance across our eyelids — with the curves of our smiles. The boundary of time ceases to exist, we are here and now — endlessly. Laying untethered from the daily struggles to assimilate and pay bills — and plan then undo plans — or concern ourselves with the still of the night — or the over thinking — the adulting — we just breath and keep breathing. Everything is well, until suddenly — everything is not.

Seamlessly, our blissful feelings — turn into abject terror. The devil in the detail reveals itself, as we begin to sink. Our picturesque beach, is nothing but quicksand — and a beautiful nightmare. Arms flailing, our hands lose each other — and our cries are silenced by the treacherous sand now filling our noses and lungs. Our demise is swift, we disappear without a trace. Ours was never an ordinary love, the tragedy finally complete with cruel irony — having drowned us without ever getting our feet wet.

All the way along each day, we chose to ignore the hopeless mess we made.

The sand resets whilst the sun still shines across the ocean, sparkling like the contents of a Tiffany jewel box.

In the background the moonlight spills in as it always does, as the sun disappears beneath the ocean just like it always does. The stars arrange themselves like the Universes biggest choir, they twinkle in breathtaking harmony — along to the symphony of yet another stupid love song.

Navigating Directed Graphs
By: Erick Katzenstein
Tags: D3js, Directed Graph, Data Science, Graph, Data Visualization

Introduction

Navigating a large directed graph is an exercise in untangling a hairball. Take the complexity of a city and remove all of its urban planning — at Enigma, this is often the convolution we’re dealing with in our datasets. In the following paragraphs we explore how to unravel these tangled messes and get to tangible insights.

Force-Directed Graphs

The visualization above represents committee-to-committee transactions for the 2017–2018 election cycle (source: FEC). Looks like a lot to figure out, but here’s the kicker: this graph represents just 2,000 transactions, while the dataset has over 850,000 total committee-to-committee transactions.

This chart is a force-directed-graph (FDG), a clever tool for visualizing complex networks with a physics-based simulation. An FDG can be an effective tool for capturing the birds-eye view of a network topology. One can use it to spot local clusters, densities, and overall distribution.

While an FDG is a good summary of a network, it falls short of comprehensive. The above network is useless to study as an interface — we need to use network algorithms to whittle down to valuable areas of focus, and then use different visualizations for more thorough analysis. The case study below is an example of this process.
Election day for in-person voting; extension for mail-in ballots

Philadelphia mail-in ballot. | Jeanette Woods for Gtown Info Hub

Today Philadelphia moves forward with voting and extends mail-in ballots by a week.

Registered voters can expect to vote at their polling locations, for Germantown: Mastery Pickett Charter School, Lingelbach School, Lonnie Young Recreation Center and Happy Hollow Recreation Center according to The Inquirer.

For mail-in ballots, Gov. Tom Wolf issued an executive order that will allow voters to return their ballots by 8 p.m.on June 9.

“I can’t do anything about the election day, but I am extending the time to actually get votes in,” Wolf said at a Philadelphia news conference. “So if you vote and the vote gets in by next Tuesday… it’ll count. An extra seven days.”

If Philadelphia should be put under curfew today, voters will not be affected. The polls will still close at 8p.m., and anyone in line by 8 p.m. will be allowed to cast their vote.

Initially the city postponed the primary election to today, June 2, due to the effects of the coronavirus COVID-19. Philadelphia, Pittsburgh and four other counties are the only PA areas to be allowed to submit mail-in ballots with the new deadline.

Rapid international expansion for Nauticus Blockchain
By: Nauticus Blockchain
Tags: Nauticus, Nts, Blockchain, Cryptocurrency, Bitcoin

The rapid international expansion of Nauticus Blockchain has gathered pace with a new office in Shanghai, a new representative in Taiwan and a signed agreement with Token News in Hong Kong for promotion throughout Asia.

The Shanghai office will focus on eCommerce, strategic alliances and assisting Chinese blockchain projects to list on Nauticus Exchange.

Nauticus has also signed a preliminary agreement with Token News in Hong Kong to market and promote the project in Japan, Korea, Hong Kong and the Philippines.

Token News has been involved in numerous successful projects and is very connected in the blockchain community.

Nauticus has also entered a partnership with a top Taiwanese blockchain expert to promote the project in the province.

“These announcements are only the start of Asian expansion and we will be doing more in other markets within the next few months,” said CEO Bryan Ng, adding the focus was now turning to Europe.

“We are forming partnerships and alliances to help provide a localised service, region by region, country by country. No other exchange is doing this.

“I believe in my team and I’m 100% confident we will conquer the worldwide exchange market and be listed as one of the top exchanges on CoinMarketCap.”

COO Jonathan Chang is currently in London meeting with fund managers and potential partners at events including the Blockchain Alternative Investment Conference.

Nauticus is in the final month of its ICO, having already signed up almost half a million registered users and raising more than $16 million USD ($21.5 million AUD). That’s more than Binance raised during its successful ICO last year.

Previously announced international alliances include blockchain-based Chinese eCommerce platform Jufuchain/Badou Mall, along with Galaxy eSolutions — an eCommerce platform in Hong Kong. Nauticus has also engaged a large Chinese manufacturer to conduct research and development to improve the efficiency of energy intensive blockchain mining machines.

Code Smell 32 — Singletons

The most used and (in)famous design pattern in the world is causing us great harm.

Problems

Coupling

Testability

Accidental implementation problems.

Multi threading issues.

Static methods polluting.

Object creation contract violation.

Bijection mismatch.

Memory issues.

Premature Optimization.

Solutions

Avoid it. Use contextual unique objects. Benchmark object creation.

Examples

Database Access

Globals

Loggers

Helpers

Sample Code

Wrong

God is the archetypical singleton example.

Right

Detection

This is a design pattern. We should avoid it by policy.

We can add linter rules for patterns like ‘getInstance()’ so new developers cannot infect code with this anti-pattern.

Tags

Globals

Conclusion

This is an historical mistake already acknowledged by the community. Nevertheless, lazy developers bring it again and again. We need to reach a consensus on its drawbacks.

Relations

Crypto Slang Glossary

“Stop talking like a nocoiner, DYOR and HODL”

Wait… What…?? Crypto slang could be indecipherable sometimes.. Are you caught in a bind not understanding what others are talking about in the middle of a crypto discussion?

Here are some slang you have to know if you want to sound like an expert：

DYOR — Do Your Own Research

Are you annoyed by the people that just won’t stop asking questions when all the answers are clearly easy to find?

When this happens.. Say “DYOR” !

HODL — Crypto slang for hold your coins.

“HODL HODL HODL and wait for the moon! “ Yup, that’s right. Probably the most frequently used word in the crypto world when it’s at the wake of a price fall.

Nocoiner — A person has no Bitcoin (or other cryptocurrencies)

Symptom 1: A person who likes to talk proudly about how he/she will neeeeever buy and own any coins

Symptom 2: A person just simply doesn’t own any coins

If a person meets any of the symptoms above, then it’s known as a nocoiner, as he/she does not own any coins.

AE(Aeternity) on Coindelta

Details below…

Dear Community,

We are happy to announce that we are listing AE(Aeternity) on Coindelta. Deposits and Withdrawals are now live and trading commences at 9:00 PM today (14th June, 2018).

Aeternity on Coindelta

Things to keep in mind before you start trading :

The withdrawal fee for Aeternity(AE) will be 1.2 AE Minimum deposit for AE is 2 AE

What is Aeternity(AE)?

Aeternity is a new platform for decentralized apps (dapps) launched in testnet in 2017.

Aeternity Features :

It includes a decentralized oracle machine that brings in data from outside sources for use in smart contracts. It also uses prediction markets for various voting and verification purposes within the platform. Project focuses on increasing the scalability of smart contracts and Dapps Aeternity accomplishes scaling by moving smart contracts off-chain. Instead of running on the blockchain, smart contracts on Aeternity run in private state channels between the parties involved in the contracts.

Founded by a long-time crypto-enthusiast and early colleague of Vitalik Buterin, Yanislav Malahov, Aeternity has quickly risen to the top 40 projects in the world by market cap.

Some more information about Aeternity(AE)

Aeternity scales through state channels that run smart contracts. It introduces a new language that supports formal verification and allows to write simpler, safer code. The VM accommodates compiled solidity contracts. Aeternity uses an ASIC-resistant, memory-bound Proof-of-Work (PoW) with less than 15 seconds block time. It features an integrated naming system and oracles, which could be used to request and access data from various data providers.

Most importantly, all components are native features of the Aeternity system. They are not meta layers on top of a blockchain (like Lightning, Raiden, Oraclize), but parts of the core protocol. This ensures unmatched efficiency and significantly reduces the cost of running smart contracts and making lightning fast transactions.

Stay tuned for more announcements!

How to Split a String in JavaScript
By: Javascript Jeep
Tags: Web Development, Coding, JavaScript, Javascript Tips, Programming

Understanding the Split Method in JavaScript

Image taken here.

The split method spilt the string into array of substring based on the pattern provided.

Example

let numbersStr = "1,2,3,4,5"; let numArray = numbersStr.split(","); console.log(numArray); // ["1","2","3","4","5"]

In the above example , the split method will loop through all the character of the string , if the pattern provided is found then the split method will collect the characters looped before finding the pattern and join all the characters as a string and pushed that string into an array .

If we don’t pass any pattern then the entire string will be pushed to an array and returned

numbersStr.split(); // ["1,2,3,4,5"];

If the pattern passed is the first character of the string , then an empty stirng is pushed into the array .

numbersStr.split("1"); // ["", "2,3,4,5"]

Also if the pattern passed is the last character if string , then an empty string is pushed to the resultant array.

numbersStr.split("5")' // ["1,2,3,4", ""]

If we pass pattern as empty string the each character of the string is splitted and pushed into array

numbersStr.split("");

// ["1", ",", "2", ",", "3", ",", "4", ",", "5"]

We can also pass number of split operation to be done by passing the limit param.

numberStr.split(",", 2); // ["1", "2"]

If we pass limit as 0 then an empty string will be returned

numberStr.split(",", 0); // []

Real world Example .

Getting the value from css property in JavaScript .

let divHeight = document.getElementById("div1").style.height; //10px let height = divHeight.split("px"); console.log(height); // "10"

2. Reversing a string

let name = "test"; let splittedArray = name.split(""); // ["t", "e", "s", "t"] splittedArray.reverse(); // ["t", "s", "e", "t"] let reversedString = splittedArray.join(""); // tset

I’ve Locked Myself (Naked!) Outside My Apartment
By: Daniele Ihns
Tags: Shame, Short Story, Humor, Thriller, Adventure

I’m at that age where I’m old enough to know better. Yet, just last week, I locked myself (naked!) outside my apartment.

It was 6 o’clock in the morning and my REM sleep was interrupted by an urgent need to pee. I got up from my bed, 90% asleep, 100% au natural, and rushed to the bathroom (yes, I live alone and during the night it can get really hot when the radiators are on so I sleep without clothes).

Consumed in a new-born style of anger, I smashed closed the door behind me and proceeded to sit on the loo.

Except the loo wasn’t there. I went through the wrong door and was now standing in nature’s garb outside my front door.

As the adrenaline started to kick in, I became 100% awake to the fact that my elderly neighbors would soon be making their way down those stairs, fully dressed, and that would be it. They would take one look at me and my life would be over.

“Oh! The horror!” I could hear them saying, inside my head, in their posh elderly accents.

PANIC. I was desperately trying to re-enact the mindfulness exercises from leadership training and calm my mind just enough so I could think my way out of this situation. But, trust me, there’s no such thing as a naked leader in the corridor at 6 am.

The need to pee was too intense for me to sit down and cry so I ran down to the garbage room in the cellar, trying to dodge as many security cameras as I could on the way.

I opened each of the trash containers looking for anything I could use to hide my shame. A bin bag, an old rag, a cardboard box. Anything would have worked at this point. But nothing prepared me for what I was about to see.

An overcoat! An overcoat?!! An overcoat!!!!

Someone had thrown away a perfectly good black woolen overcoat in the bin exactly when I needed it the most.

It couldn’t be. Something was wrong. Was I still dreaming?

No, I wasn't dreaming. This was actually happening.

I took the coat and ran across town, barefoot, to my ex-boyfriend’s house to pick up the spare key that was still sitting there since we broke up months ago. It’s Autumn. I live in the mountains. It snowed last week.

My ex lives just 10 minutes away but I had to go past the school and across the central park to get there. By now it was already that time when kids are being dropped off and joggers are out and about. They looked at me in a strange way. I couldn’t feel my feet. But at least I had my overcoat.

It’s hard to describe that feeling, a mixture of gratitude with “why me??”

Please pause and try to picture yourself in this situation for a moment.

No, you can’t, because you’re a fully dressed privileged kid who doesn’t know what it’s like to have to explain to your ex why you ended up naked in your corridor at the break of dawn!

The horror! The horror!

We don’t talk enough about plain stupidity…

A New Day

What if?

Photo by Jordan Wozniak on Unsplash

What if I woke up and the nightmares were over?

If I could turn on the news just to hear about a car accident,

my heart would float away with the clouds.

What if all the baseless hate melted into the soil

to be transformed by micro-organisms, watered by rain,

warmed by dawn, until it grew into a radiant love which

stretched tall, reaching for the sky like a sunflower.

What if you saw the flower and gasped, remembering

the first time you noticed the beauty of existence,

when you were a child and you knew what was true.

What if the light of sunrise spread across the world, turning

everything gold and pink for a minute or two, enough

time to remind us to open our eyes and our minds

to reality, which is not hidden in screens but out there.

What if we could learn from the life of our magnificent Earth

that everything is connected and that this is all there is.
Why we’re going public with Secure Data Kit’s product roadmap

Secure Data Kit enables really passionate people all over the world to leverage data for good. We have community members who are dedicating their lives to…

Our members have trusted Secure Data Kit to collect, share and analyze data to support these various causes. We — the Secure Data Kit team — want to show our appreciation for and commitment to these missions by bringing a new level of transparency to our development plan. That’s why we’re publicizing our product roadmap, allowing our members a look into what our team is focusing on now, and what we plan to focus on over the next 12 months.

So, what’s the point of all this?

Collaboration: Our community members share their ideas with us all the time. We’ve always kept track of each request, but have never had a good way to let everyone in on what we’re doing. Publicizing our roadmap will allow us all to be on the same page (literally) when discussing the direction of the product with our members.

Accountability: Because our roadmap has always been hidden from our members in a private internal document, we had a huge lack of accountability. While we typically did a pretty good job of staying on track, publicizing our roadmap will remove any temptation to say one thing and do another. Even more important than seeing our product grow is seeing the trust our members have for us grow, and allowing members the information they need to hold us accountable is a small step in that direction.

The Secure Data Kit Roadmap went live today, check it out!

The Importance of Cultivating Self-Awareness in Parents

The last couple of years, I’ve noticed a shift: the carefree attitude of childhood and “I don’t care what anyone thinks of me” slowly drifting towards fear of the critical eye. While he once jumped in with both feet, he began to hesitate. This left him sometimes scared to try new things and run the risk of looking silly.

Recognizing this, I’d been encouraging him to join different activities outside his (and my!) comfort zone. We’d tried things like a ropes course in the treetops and zip lining. We even attended an entrepreneurship event together, where he was the only child present.

Feel the Fear and Do It Anyways

More recently I began advocating (again) for him to try a different position in soccer. He’d only played one position since joining the league three years ago and held on to it tight.

Given he’s in a recreational league and still young, I knew the window would soon close for him to explore other positions.

With his dad as the coach, one might think I had an in, but that’s not the case. We share different parenting philosophies.

So with a quiet desperation, I appealed to our son, explaining the benefits of trying something new and sharing examples of times when I also tried new things and failed. More importantly, sharing the lessons I had learned and how I had grown from my so called “failures.”

And I didn’t have to look far to find examples. This year he’s seen me get more uncomfortable that I have been in a long time. Leaving my corporate job to pursue a dream, learning about tech, pitching concepts and building a new community left me often feeling like I was riding a rollercoaster.

Throughout my journey, I’ve continued to share my experiences and challenges with him. Things like my struggles with staying disciplined, managing my thoughts (and negative self talk) and cultivating belief in myself.

They reside all along the edge of a city

Hidden behind buildings and freeways

Their souls stifled by cyclical ignorance

Even when people call out the injustice

The pain on the streets still rises alone

Unseen by the systems that manifest it

Dark Ages Act II

PIXABAY Sparklelk

There is nothing new that can be said

About the reasons reason’s fled

Out of the halls of the tasteless

Into our barbarian hands.

It can only be time to begin anew,

(To leave behind what has run askew

In the courts of the uncivilized)

Upon these leveler lands

Opportunity does now arise

To see advantage in these times

Abandon palaces of blame

Build bonds that break walls.

May outcast ones show the way

And assume their rightful place

Connecting us, so none accuse

Another hero calls.

We’ve been dancing on the fringe

For someone to invite us in

Because we’re prone to hesitate

On our common earth.

We’re hoping for a primal place

Waiting one to set a pace

But therein lies the rub:

You or I go first?
Network sparsity and rectifiers
By: Cédric Bellet

Activation functions in networks: the case for rectifiers

In the rest of this article, we examine why rectifiers stand out as a choice of activation function. We start by ruling out linear neurons as candidates for neural networks, then explore the advantages of rectifiers over comparable neurons, like the sigmoid logistic ones.

Linear activation neurons do not stack. N layers of linear neurons are equivalent to a single layer of linear neurons, given how information propagates in neural networks. This defeats the purpose of building neural networks, and a mental note that any good activation function candidate for a multi-layer network will need to be non-linear.

This defeats the purpose of building neural networks, and a mental note that any good activation function candidate for a multi-layer network will need to be non-linear. Sigmoid activation neurons, which we know are able to perform logistic regressions on their own, work fine in deep neural networks too. We simply note that all neurons in a network of such neurons are always active and firing signal.

activation neurons, which we know are able to perform logistic regressions on their own, work fine in deep neural networks too. We simply note that all neurons in a network of such neurons are always active and firing signal. Rectifying neurons are neurons using x → max(0, x) as their activation function. They have no clear use as single neurons but actually do well in deep neural networks. In Glorot et al., we learn that rectifying neurons have three interesting properties:

“Rectifying neurons are an even better model of biological neurons and yield equal or better performance than hyperbolic tangent [and sigmoid] networks in spite of the hard non-linearity and non-differentiability at zero, creating sparse representations with true zeros, which seem remarkably suitable for naturally sparse data.” (Glorot et al., 2011)

What do those properties mean?

1. Biological plausibility

Biological plausibility is the quality of a model being close to biological reality, with the hope that learnings from the model could inform our understanding of biology, or that conversely, that the model could inherit some of properties of the reality it drew inspiration from. Here, biological plausibility is about two things: (a) plausibility of the neuron’s activation function, and (b) plausibility of the neural net’s overall behavior.

(a) Biological neurons are units that receive an electrical current as input, and fire output electrical signals characterized by their frequency if the input current is strong enough. In the absence of input current, biological neurons are not activated, and with increasing current, their fire rate increases.
When life makes up the balance sheet…

It started in 2012 with your aunt. You probably know by now you’re number four in the family, not number three. There was a baby before your nephew Owen came around. The first of your generation was a girl called Juuls. The pregnancy went all fine, until a simple cystitis turned into a ripped appendix. I was at a concert when I got the call. And got someone to drive me to hospital as fast as he could. Invasive surgery followed immediately and your aunt barely survived. She was kept in a coma for two months.

Juuls was born but never grew older than 21 weeks of age.

Life stopped. No-one should ever have to bury his or her child. It was one of the most tragic moments in my life to date. I was lucky to have your mum around. She really helped me keeping me from depression and losing my mind. She managed to pick up the pieces of what was left of me, to keep my head high and to look at a brighter side of life. My sister still lived, and I should be thankful for that. I guess in these times anything we call ‘Fair’ or ‘Justice’ there doesn’t exist. It’s just life.

So, your aunt slowly recovered and life and opportunity found it’s way back into my brain. Only months later, I took a gamble. I always envisioned myself as being an entrepreneur, a starter and creator. Someone who creates business, stories or product from a blank piece of paper. So, together with uncle Thomas and our Finnish friend Vesa, I started a new business in an area I didn’t fully understand. I shared this crazy visionary idea of creating a way to share moving pictures. Just like the ones you’d come across in the stories of Harry Potter. I did a ton of research about creating apps for smartphones and had my contacts in the Dutch Start-up scene. It felt like 1+1=10. We had a dreamteam, a beautiful working product and some investment to get started. A dream come true!

Well, when you land in Schiphol in Amsterdam today, you don’t see a 30 story building with the name Framely on it. Sorry pal, that magical idea didn’t fly. In fact, it was the first time I had to make responsible decisions and bite a bullet. Face reality once again. My start-up failed. My responsibilities didn’t leave me though. Paying tax doing the admin. Paying rent and making sure I got a new gig.. But when you put in the time, the effort the sweat and the tears for so long, killing your darlings isn’t that easy… I was incredibly frustrated with myself, feeling useless and stupid.

While being in this state of sleepless nights and frustration — the most peculiar thing happened to your mum. I thought I had my share, but I was about to learn to true meaning of grit…
