สร้าง Single Page Application ด้วย Vue.js และ Firebase authentication
By: Wattanachai Prakobdee
Tags: JavaScript, Vuex, Bnk48, Vue, Firebase

Authorization check and log out from the app

หลังที่เราทำการ sign-in เราได้ทำการ reload หน้า ซึ่งผลจากการ reload คือทำให้เกิดการ reset Vuex state เป็นค่า initial value ซึ่งเราต้องทำการจัดการปัญหานี้ ด้วยการใช้งาน Firebase ในการแก้ปัญหา โดยที่ทาง Firebase ได้มี method onAuthStateChanged ซึ่งจะช่วยให้เราตรวจสอบว่า user คนนี้ได้ทำการ sign-out ไปแล้วหรือยัง

ทำการเปิด src/main.js และเพิ่ม created() lifecycle hook ของ Vue instance โดยทำการเรียก dispatch autoSignIn โดยส่ง firebaseUser เป็น argument ดังนี้

main.js

/* eslint-disable no-new */

new Vue({

el: '#app',

router,

store,

render: h => h(App),

created () {

firebase.auth().onAuthStateChanged((firebaseUser) => {

if (firebaseUser) {

store.dispatch('autoSignIn', firebaseUser)

}

})

}

})

จากนั้นทำการเพิ่ม autoSignIn action โดยทำการ set ค่า firebaseUser ดังนี้

action.js

autoSignIn ({commit}, payload) {

commit('setUser', payload)

}

ถึงตอนนี้เราก็มี function สำหรับ sign-up และ sign-in และหลังจาก sign-up และ sign-in เรียบร้อยแล้ว เราได้ทำการ redirect user ไปที่หน้า BNK48 ทีนี้เราจะทำ function สำหรับ sign-out และหลังจาก user กด sign-out เราก็จะทำการ redirect user ไปที่หน้า sign-in

อ๋อ ลืมไปเลยครับ เรายังไม่ได้สร้างปุ่มสำหรับ sign-up และ sign-in เลย งั้นมาสร้างพร้อมปุ่ม sign-out เลยละกัน ทำการเปิด src/App.vue

App.vue

ทำการเพิ่ม isAuthenticated property และ toolbarItems property ใน computed โดย isAuthenticated property จะทำการตรวจสอบว่า user ได้ทำการ sign-in แล้วหรือยัง และ toolbarItems property จะเป็น list ของปุ่ม sign-up และ sign-in

isAuthenticated() {

return (

this.$store.getters.getUser !== null &&

this.$store.getters.getUser !== undefined

);

},

toolbarItems() {

return this.isAuthenticated ? [] : [

{

icon: "face",

title: "Sign Up",

link: "/singup"

}, {

icon: "lock_open",

title: "Sign In",

link: "/singin"

}

];

}

และทำการเพิ่ม userSignOut method

methods: {

userSignOut() {

this.$store.dispatch("userSignOut");

}

}

พร้อมทำการเพิ่ม userSignOutใน action โดยทำการ set user state เป็นค่า null พร้อมทำการ redirect ไปที่หน้า login ทำการเปิด src/store/actions.js และเพิ่ม

userSignOut ({commit}) {

firebase.auth().signOut()

commit('setUser', null)

router.push('/signin')

}

จากนั้นทำการเพิ่มปุ่ม sign out โดยเปิด App.vue ทำการแทนที่

...

Mystery ‘Israeli expert’ denies Russian role in Novichok affair
By: Brian Whitaker
Tags: Propaganda, accused of fakery, Russia

Last week a website called News Front published what it claimed was an interview with Alexander Brass — described as a “writer” and “an Israeli expert on international terrorism”. Based on his purported knowledge of the way secret services work, Brass was quoted as saying Russia could not be responsible for the “Novichok” poisonings in Salisbury.

“If the [Russian] GRU needed to kill Skripal, he would now be dead,” Brass allegedly told the website. “This is a well-thought-out strategy of demonisation and international isolation of Russia.”

Within a few days, the “Alexander Brass” interview was also featured by Russia’s Sputnik News and on the website of fantasist David Icke. It was re-published in the US by a right-wing conspiracy-theory-and-pseudoscience website, The Liberty Beacon, and on the website of its European offshoot,

Europe Reloaded.

On Twitter, the interview was promoted by George Galloway, the British former MP and admirer of Saddam Hussein, who described it as “a must read”:

Professor Tim Hayward of Edinburgh University, a prominent figure in the Russia-friendly Working Group on Syria, Propaganda and Media, joined in on Twitter too:

There are doubts, though, about whether Alexander Brass, the writer and Israeli terrorism expert, really exists. A Google search reveals no trace of him except in connection with the News Front interview. Conceivably he was using a pseudonym, though News Front doesn’t say so.

The question of Brass’s identity is relevant because News Front has previously been accused of fakery. The website is based in Crimea and its editor-in-chief is Konstantin Knyrik, a former pro-Russia militiaman who also chairs the Crimean branch of Russia’s ultra-nationalist Rodina party.

News Front publishes in several languages, including German, Spanish, and English, and has been described by Time magazine as “among the better-resourced players in the Russian media ecosystem”. Last year it was the subject of particular concern in Germany where there were reports that it was trying to influence the Bundestag election. A study by the Atlantic Council’s Digital Forensic Research Lab found that News Front was one of the three main outlets for Russian propaganda in Germany, alongside Sputnik and RT.
Ad-injecting malware hijacks chrome, edge, firefox

Tags: Cybersecurity, Google, Malware, Microsoft, Chrome

Source: AVG

Did a higher number of advertisements show up at the top of your search results while looking for items online than usual? You may have fallen victim to the Adrozek malware ad-injection, If you use Microsoft Edge, Google Chrome, Yandex Browser, or Mozilla Firefox.

Cybercriminals have been forcing it on users since at least May 2020, according to Microsoft, and it was detected on over 30,000 computers per day at its peak in August.

“Adrozek illustrates that even threats that are not considered immediate or important are becoming increasingly more complex. And while the primary objective of the malware is to inject ads and refer traffic to certain websites, the attack chain includes advanced activity that enables attackers to gain a strong foothold on a computer,” warned the Microsoft 365 Defender Research Team.

Malware Adrozek is capable of:

Modify browser extensions by inserting malicious scripts to them, which inject ads into search results with extra scripts.

Modifying unique DLLs (browser-dependent) to disable security controls that can detect its behavior

Modify the security settings/preferences of the browser to (for instance) add permissions that allow malicious extensions to have more control over Chrome APIs or prevent browsers from upgrading to the latest versions.

Modifying multiple configurations of systems to monitor the compromised computer even further and maintain persistence

Stealing passwords from users (on Firefox)

Microsoft clarified, “Adrozek is installed via drive-by download on devices.” “We saw 159 separate domains used to spread hundreds of thousands of unique malware samples in our monitoring of the Adrozek campaign from May to September 2020. This infrastructure is bound to grow much further while this initiative is underway.

Via affiliate advertisement programs, the crooks behind this initiative are earning money, i.e., they are paying for traffic referred to associated sponsored sites. Microsoft claims they didn’t see malicious sites pointing to the injected advertising, but that could change easily.

Prevention & Mitigations

Microsoft says its Defender Antivirus on Windows 10 blocks Adrozek malware ad-injecting and other security solutions are likely to do so by now.

Users who were infected were told that their browsers should be re-installed.

“In view of the massive infrastructure used to distribute this threat on the web, users should also learn about the prevention of malware infections and the risks of downloading and installing software from untrusted sources and clicking on suspicious websites for advertisements or links,” Microsoft added.

For companies, for these types of attacks, defenders should look to reduce the attack surface. Control of applications enables organizations to enforce the use of only approved apps and services.

The Attitude You Need to Adopt to Stop Procrastinating Your Workout
By: Devin Arrigo
Tags: Life Lessons, Health, Fitness, Running, Life

Running is a sure-fire way to reconnect with all the good things in your life. It’s a way to remember what you have to be grateful for. And most importantly, it’s a reminder that you’re still alive.

My friend once told me, “I despise running.”

“My legs hurt, my lungs burn, and the whole time I’m in just pain. Why would I do that to myself?”

I get it. Most of the time, running sucks. It’s uncomfortable and usually pretty painful.

However, everyone that runs deals with these exact pains and discomforts. From newbies to experienced runners who’ve been pounding the pavement for several years. Regardless of your experience, running will humble you.

That’s the very nature of running — it’s oftentimes unpleasant. But in that discomfort are powerful lessons about life, gratitude, and perspective.

Your lungs are screaming for air. Your legs are burning and feel heavy. And the whole time, your brain is pleading with you to stop. It’s uncomfortable and painful — it sucks.

But that feeling — the feeling of suck — means you’re alive. It means you’re still breathing. You’re still kicking. You’re still on this earth.

That’s something to be grateful for — breath in your lungs. Don’t despise running just because it’s uncomfortable. Instead, be grateful for the opportunity to reconnect with the little things in life.

A breath of fresh air. A cool breeze of wind. The warm sun shining on your face.

There are always going to be hardships and difficulties in our lives. But running is a way to temporarily avoid the crap and just be. To be alone with yourself. With your screaming lungs and burning muscles.

To reconnect with what it means to be human.

Sure, running isn’t always enjoyable or fun. In fact, it’s usually painful and unpleasant. It sucks. But that feeling of your lungs burning or your muscles aching is a sign that you’re still alive.

Enjoy that feeling. Because tomorrow, it could all be taken away.
Are Black and Brown People Enemies Or Friends?

Tags: White Supremacy, Racism, Equality, BlackLivesMatter, Corporate Culture

White people usually think that brown and black people are allies, and that’s a bit of a myth.

Photo by Mitchell Luo on Unsplash

I once worked in a team led by a bitter, racist, and insecure white lady. She, Linda, was given responsibility for international markets but constantly mocked black and brown people in those countries. I was astonished at how she couldn’t be bothered to even learn how to spell Turkmenistan properly. I mean really, checking the right spelling of that country would take 20 seconds in a quick Goggle search, but she simply couldn’t be bothered.

After working with her for a while, it became clear to me that she thought non-western countries were inferior and she treated people in these countries with disrespect — very different from how she would treat a white American, German, South African, or Australian for that matter.

While her behavior might not have always been apparent to other white colleagues, all the black and brown people on the team knew that she was inherently racist. Unfortunately, leadership did not pick up on this or chose to ignore this and continued to increase the number of black and brown countries under Linda’s responsibility.

Marie Forleo: Mastering the Art of Good Hope Marketing

A simple formula and case study in clear personal branding

Photo by John Schnobrich on Unsplash

You’ve built something.

You’re hoping you can spread the word about what you’ve made. We all know that traditional “hope marketing” doesn’t work. That’s the kind of marketing when you make something or provide a service and just hope the customers will come.

It’s the marketing equivalent of fishing with an empty hook. OK, you’re putting something out there, but there isn’t even any bait on your hook.

There’s no compelling reason for a customer to actually buy something from you. You don’t even know if there are any fish in the water!

But I’d like to propose a new kind of hope marketing: one that really works. It all stems from one simple question.

What do people actually want when they hire you or buy from you?

That’s one of the most important questions in marketing. Think about it:

People visit Facebook, because they want it to entertain, inform or connect them.

People donate to a charity, because they believe the work of the charity will make things better for others

People relocate to a nice area, because they believe it will improve their quality of life.

So when people buy from you, they are hoping for something. It has to be clear what it is they are hoping for; you have to know what it is they are hoping for.

The Broken Chair

An existential poem about the loss and metamorphosis

Photo by Dan Meyers on Unsplash

What becomes of you,

once you’ve changed?

when those cracks cannot

be mended whole again

when you lost

pieces that gave you purpose

Now but a ghost limb longing

crying out, o! great woe

lost child in the mystic woods,

falling headfirst into a well,

wanting warmth again

falling upside down,

image void of

sound.

But as the golden watch did bestow

shaky hands of a carpenter's woes

As the door creaked closed

you knew life had ended

new beginnings sat screaming

once smooth, full moon glisten

now rough and ragged,

dust in an old basement

cancer in an old colon

grows.

The shadows of you

used to be brighter

did you know

that was your final fall?

one last drink,

a soliloquy to tragedy

When you sang

silent hymnals

giving comfort when

nobody asked for it

yet there you were

waiting for hope

to spill out of the river

bed.

and now the world coughs

itself into an early grave

I sit alone thinking of thee

for what happens when

meaning is chipped,

when the coffee smell

no longer migrates

when insomnia becomes king,

and upon that empty wall,

I wonder where you are

I wonder if that piece,

can be mended

anew.

And now what are you?

were you ever just

the thing you allowed

others to see,

or were you more, beyond

that bourbon stench,

and liquor hardened soul

the words that sat

showing us all

the long wait until

rebirth.

At the End of the Rainbow
Tags: Life Lessons, Literally Literary, Poetry, Free Verse, Life

The end of the rainbow came suddenly,

and there was no pot of gold of you.

No wonderfully strong biceps

or big, inviting chest

for me to kiss over and over

and over again.

The chest I want to

hold me so tightly,

to keep me warm,

to lay my head upon.

And no deep voice

that can bring me to my knees

with just one word.

The voice I want to hear everyday,

every night, every second.

No, there is no pot of gold of you

at the end of my rainbow.
Don’t Overdo It: Take It Slow To Avoid Pain
By: Arpit Khemka
Tags: Soreness, Heavy Lifting, Pain Recovery, Inflammation, Physical Therapy

Don’t overdo it to avoid pain. Why do we feel pain in our muscles after a strenuous workout? According to the Hartford Courant, it could just be our body’s way of protecting us.

“It’s actually your body pushing back, a condition that physicians and physical therapists call delayed onset muscle soreness (DOMS). The scientific explanation of it is rather long and involves such things as lactic acid build-up and proton transfers. What’s important to know… is that its purpose seems to be getting you to stop doing whatever it is that you’re doing long enough for your body to repair the damage you’ve already done.”

Says one physical therapist, “Soreness can be a good thing.”

Sore muscles that are felt within a day or so after strenuous activities “are a sign that the strain of heavy lifting or stretching caused microscopic mayhem in the cellular compartments that make up each muscle fiber. White blood cells, nutrients and a host of biochemical agents flood the injury site. Inflammation at the site triggers a biochemical landslide of sorts that wakes up the nervous system’s pain sensors.”

If DOMS should strike, “one should gently stretch and continue to exercise lightly through the soreness,” says the physical therapist. “The key is to use a progressive program.”

That’s exactly what SimpleTherapy is — a progressive, adapting program that will start easy and build up gradually over time, as you advance in readiness. Take a look at the range of SimpleTherapy pain recovery programs available for your needs.
The Therapy of Art
Tags: Self Help, Creativity, Writing, Art, Life

So, what purpose do art and creativity serve during a pandemic? Boccaccio’s The Decameron tells the tale of seven women and three handsome men who flee Florence and the Plague of 1348. They settle down in a country palace for fourteen days and entertain each other with rounds of dirty stories showcasing all facets of humanity. The characters used storytelling as a way not only to survive but to maintain the will to live.

Maybe we’re not so different. The bookstore was right up there with the liquor store in the days before lockdown, and many independent shops are still doing a booming business online. Since self-isolation began, people worldwide have taken to social media to tell their stories, recite their poetry, show off their creative recipes, sing, paint, and entertain each other in any way we can. In Milan, both in Boccacio’s time and now, people took to their balconies to sing and play music.

The need to connect to creativity is eternal and goes both ways.
Don’t Be A Sheep — Follow Your Own Path.
By: Kerry Jane Rider
Tags: Spirituality, Personal Development, Self, Mindfulness, Life

We are affected and influenced by others even when we don’t know it. Social media in particular is renowned for its ability to do this. My Twitter feed is understandably full of posts which I don’t want to read continuously right now not because I don’t care about the topics but because I don’t want my head filled with other peoples’ ideas and projections. I want to take time for myself and make up my own mind how I feel and how I want to react. I don’t need to be coerced or brainwashed in order to reach a rational decision of my own.

We are all individuals with our own unique wiring and our own ways of thinking and doing which won’t suit everyone. That’s fine because we can’t be friends with everyone can we and nor would I want to be if I had to become a bully to achieve that friendship.

What we can do is show respect to everyone and control how we act and react.

I think the most important thing to remember is very simple and that is if we can’t say or do something which helps a situation or makes it better then it is probably best to say or do nothing at all.

We are each the centre of our own world. We are ultimately responsible for ourselves, the way we live our life, the decisions we make, those we help, those we hurt, the causes we put our names too and the stands we make in the name of justice — all relative to our own perception of course. My perception and yours will never be the same. The way we each see and understand something will never be the same. This is why we are unique individuals. Sometimes it is helpful for us to work with the collective and to be a part of the tribe but mostly it is not. We should be very selective about when and how we choose to join forces and know when it is best for us to remain apart.

If you choose to jump on a bandwagon, whatever it is, make sure you do yourself the service of really thinking it through for yourself, in your own way and rationalise it deeply before you find yourself doing or saying something you might spend the rest of your life regretting.

Maybe I should invest in a notepad for all my ideas. Yea I’ll do that.

The Benefit of Constant Contact

PTs: Here’s how to tap into the power of the reminder

By Mark Spencer (VP Marketing of In Hand Health, LLC)

A little encouragement can go a long way. It’s cliché, sure, but it is also fact according to a recent study published in the Journal of the American Medial Association.

The JAMA study included 700 people with heart disease. Half the group received four text messages per week that were customized to its specific needs such as reminders to take a daily walk, tips to quit smoking, and dietary guidelines that reduced consumption of fried and fatty foods. The other half received normal care for their specific conditions without any text messages or other reminders.

At the end of the experiment, the patients who received the texts had lowered their cholesterol and blood pressure levels more than the other group. They also lost more weight and showed higher compliance rates with exercise programs and quitting smoking than the patients who did not receive the texts.

Can this practice be extended to physical therapy patients? It sure can!

There are various methods for sending quick reminders to patients. Whichever method you choose, be sure all communications are secured by HIPAA-level protections first and foremost.

Another consideration is effectiveness of the message delivery. If possible, send your notifications directly to a patient’s smartphone with as opposed to an email address that a patient might not check everyday.

It would also be ideal for the reminders to be part of a bi-directional conversation (patient to therapist, therapist to patient) and captured in a record that can be reviewed at anytime.

If you’re looking for such a solution, Physical Therapy In Hand includes a messaging center that enables secure text messages to be traded between a therapist’s laptop or tablet directly to the In Hand Health mobile app on a patient’s smartphone.

In addition to simple text messages, voice clips, videos, and photos can also be shared in case communications need to extend beyond simple encouraging messages. In the very near future, Physical Therapy In Hand will also include the ability to send notifications that surface immediately on a patient’s smartphone.

One day, a young guy was on an elevator. The elevator stopped at another floor, and another person then got on.

That other person… was Richard Branson.

But the young guy didn’t recognize him.

Branson said, “Hello.” The young guy replied, “I’m sorry, but I think I’m in the wrong elevator. Also, pleasure to meet you.” Branson then looked right in the guy’s eyes and said, “No… you are exactly where you need to be. My name is Richard Branson.”

And then the elevator let the two off… at the top floor.

Who’s the young guy in this story? Here’s the thing: it’s not even a guy at all. In fact, he is the abstract concept… of YOUR POTENTIAL.

Just something to think about.

DEx.top Integrates With Coinbase Wallet & Ledger, Expands International Reach
Tags: Coinbase, Decentralized Exchange, Ledger, Ethereum

Decentralized exchange DEx.top has recently announced integrations with Coinbase Wallet and the Ledger hardware wallet, expanding its availability for international users. Coinbase Wallet is backed by cryptocurrency exchange behemoth Coinbase, which currently boasts over 10 million users, while Ledger is widely recognized as one of the most secure cryptocurrency storage solutions and has over 1 million users across 165 countries.

With this partnership, users now have the option of accessing DEx.top directly through the DApp browser in the Coinbase Wallet app or binding their Ledger wallet to DEx.top for trading.

Formerly known as Toshi, Coinbase Wallet was developed by the Coinbase team itself, with the aim of making cryptocurrency management and decentralized web access as safe and simple as possible. This rebranding is a continuation of those objectives, as the Coinbase team consolidates its efforts to invest in products that will shape the future of the decentralized web. The newly upgraded Coinbase Wallet offers support for ETH, ERC-20 tokens and non-fungible collectibles based on the ERC-721 standard as well as a DApp browser that can access all third-party decentralized applications. Support for BTC, BCH and LTC is expected to be added soon.

Ledger has been no slouch either. It closed the largest Series B round ever raised for a cryptocurrency startup earlier this year, raising $75 million in a round led by Draper Esprit with well-known funds including Draper Dragon and Boost VC also participating. Ledger sold over 1 million wallets in 2017, making it the current largest hardware wallet manufacturer.

Both Coinbase Wallet and Ledger are promising represent strategic partnerships for DEx.top, which now benefits from greater access to Ledger users (who tend to have larger holdings) as well as Coinbase Wallet’s mobile audience, who can access the exchange without having to create an account thanks to the DApp browser.

DEx.top has previously partnered with two other leading mobile wallets, imToken and Trust Wallet, and is recommended through their DApp browsers. Moving forward, the exchange will pursue development of its product ecosystem through integrations with more DApp browsers and software and hardware wallets to provide greater convenience and utility for users trading on DEx.top.

As a launch event, we’re giving away custom DEx.top Ledger wallets and up to 1ETH to 10 lucky winners! Full contest details are available here.

About DEx.top

DEx.top is a decentralized Ethereum-token exchange based on smart contracts. It introduces the innovative ROC (Replayed On Chain) trading mechanism that leverages synchronized off-chain and on-chain ledgers to enable instant, low-cost trading while ensuring the security of traders’ assets. DEx.top is committed to providing secure, instant and low-cost trading for all its users.

Scatter Plot - A Tool for Descriptive Statistics
By: Koushik C S
Tags: Machine Learning, Artificial Intelligence, Scatter Plots, Data Science, Descriptive Statistics

From the above plots, we could clearly say that both plot have a Linear relationship with positive correlation, but which plot have a stronger correlation?

For that we need something in numbers to compare. Hence we use Pearson’s Correlation Coefficient.

The Pearson coefficient is a type of correlation coefficient that represents the relationship between two variables that are measured on the same interval or ratio scale. The Pearson coefficient is a measure of the strength of the association between two continuous variables. Pearson correlations are only suitable for quantitative variables.

Pearson’s Correlation Coefficient formula is

Pearson coefficients range from +1 to -1, with +1 representing a positive correlation, -1 representing a negative correlation, and 0 representing no relationship. It is independent of the unit of measurement of the variables.

The Pearson coefficient shows correlation, not causation.

The correlation coefficient between the variables is symmetric, which means that the value of the correlation coefficient between Y and X or X and Y will remain the same.

Correlations are very sensitive to outliers. A single unusual observation may have a huge impact on a correlation. Such outliers are easily detected by a quick inspection a scatterplot.

The Pearson’s coefficients for above two plot are 0.59 .Both the plot have same Correlation coefficient because left plot is nothing but Zoomed version of the Right plot.

TYPES OF CORRELATION WITH THEIR RESPECTIVE PEARSON’S CORRELATION COEFFICIENT VALUE

Positive Correlation → X variable increases Y variable also increases.(X is directly proportional to Y)

Negative Correlation → X variable increases Y variable decreases.(X is inversely proportional to Y)

No Correlation → There is no correlation between X variable and Y variable.

From the plot we can see that there exists a curve but the Pearson’s correlation Coefficient is Zero.

Pearson’s correlation coefficient only identifies a linear relationship. If any non-linear relationship exists such as a curve, circle, etc, the Pearson’s correlation coefficient value will be 0.Hence it is always better to visualize any dataset as a scatterplot to find any hidden non-linear patterns.

Correlation is only an association relationship and not a causal relationship.

Correlation is not Causation

From the above pic, we can’t say that if a person owns a cat he is likely to get struck by lightning though there exists a positive correlation. The two variables may have high correlation co-efficient value although there may not be any direct dependence between them. It doesn’t mean that X caused Y to happen or vice-versa.

The Other Side of the Fence

Not All It’s Cracked Up To Be

By Julia A. Keirns

Photograph Copyright Julia A. Keirns

I tried it once — the other side of the fence. I thought my life would be better over there. It wasn’t.

Along the way I hurt many people that I loved. Bridges were burned. It was hard to come back.

From where you currently stand it might look like the grass is greener, but that’s just because it rains all the time. Or maybe it’s because the people who’ve crossed over the fence cry a lot and their tears water the grass.

I can’t say that crossing the fence was completely a bad thing because it made me realize that what I had on this side of the fence was actually pretty good. I had gotten bored and complacent. I was not appreciating what I had and felt that I was not being appreciated either.

Crossing the fence usually requires deception and lies. Sometimes it includes illegal actions, and it always leads to regret. Sorrow and drama are all I found over there.

I vividly remember the day the gate to the fence opened back up to allow me an easy exit and re-entry back to my regular yard full of greenish-brown grass. I don’t remember hesitating. All I remember is being accepted back with open arms and glad hearts.

If I ever again begin to think that the grass is greener on the other side of the fence, I think I will just get out the watering hose and water my own grass. Maybe I will even toss out a little fertilizer while I’m at it.

Unleashing Your Daemons: Creating Services on Ubuntu

It’s not black magic, but it’s close enough

Photo by chester wade on Unsplash.

Lately, I’ve contacted several companies to ask if they were looking for new interns this summer. I haven’t yet finished my CS degree, but I want to get a feel for the real world outside the university. As a challenge, one of these companies asked me to build and deploy a small RESTful API.

Building the API was easy enough — nothing an ambitious CS student can’t handle. Once I was done polishing the final product, I uploaded the source code of my API via SFPT to the server where I wished to deploy it. I then SSH’d said server and ran the API, and it worked! But as soon as I logged out of the server, the API stopped. I couldn’t maintain an SSH session to the server 24 hours a day until the company reviewed my API. I needed the API to run autonomously on the server.

I needed to unleash a Daemon.

While unleashing a Daemon sounds fancy and exciting, I’m sorry to tell you it is actually quite the opposite. The Daemons (or services) we are going to be fighting here are just background processes that run on their own with no interaction from the user. However, I’m not exaggerating if I say I felt like a demon slayer once I had my API running as a background process.

All jokes aside, creating a Daemon is quite an easy task if you know what you are doing. Let’s get straight to it!

I always think about her every time idleness would knock on my door.

The following day after taking an entire day of strolling, just before dinner I arrived at the apartment with an amazing smell of Asian food. Comfort, I thought.

I stood at the front door of the kitchen area, and shared with her the places I saw and visited — the Eiffel Tower, Musée du Louvre, Sainte-Chapelle de Paris, and many others. She was busy cutting the vegetables, frying the chicken, and mixing sauces. She said she was cooking for her community — “Asian thing you know. I will cook for you too,” she smiled.

As our conversation progressed, she asked me questions I thought were too personal, but I didn’t mind. She was curious about my life back home, my love life, and even what I do for a living. I told myself it was fine to open up. She’s a stranger.

Then it was her turn — she shared with me about her story, how she was madly in love with a man. They both went to theatre workshops. They were artists. Then she said with her face full of nostalgia, reminiscing — “I’ve been married for years but there are nights that I would still dream about this guy I loved and cared so much when I was in Hungary.” I didn’t know what to respond but I said, even though unsure — “Maybe there are things in life that we can never forget, especially if it impacted us so much. It is alright to feel it, to reminisce maybe. And that’s beautiful. It is yours to keep.”

When it was about time for me to leave as I had to go back to Brussels, I helped her with her stuff to carry three floors to the ground. There was no elevator. She booked an Uber. Yet before she entered the car, she grabbed my hands, she looked at me and said, “I just want you to be happy.”

Her farewell to me wasn’t goodbye. Her words stayed. Maybe because until today she helped me realize a lot of things.

Maybe #Paris wasn’t called the City of Love only for those who had good and fairytale-like love stories. I was convinced it is also a place for those who experienced a kind of love that has been transforming in many ways.

It was a beautiful encounter to remember.
Robots and Religion: Mediating the Divine.

Tags: Philosophy, Religion, Artificial Intelligence, Robotics, Technology

Some 100,000 years ago, fifteen people, eight of them children, were buried on the flank of Mount Precipice, just outside the southern edge of Nazareth in today’s Israel. One of the boys still held the antlers of a large red deer clasped to his chest, while a teenager lay next to a necklace of seashells painted with ochre and brought from the Mediterranean Sea shore 35 km away. The bodies of Qafzeh are some of the earliest evidence we have of grave offerings, possibly associated with religious practice.

Although some type of belief has likely accompanied us from the beginning, it’s not until 50,000–13,000 BCE that we see clear religious ideas take shape in paintings, offerings, and objects. This is a period filled with Venus figurines, statuettes made of stone, bone, ivory and clay, portraying women with small heads, wide hips, and exaggerated breasts. It is also the home of the beautiful lion man, carved out of mammoth ivory with a flint stone knife and the oldest-known zoomorphic (animal-shaped) sculpture in the world.

We’ve unearthed such representations of primordial gods, likely our first religious icons, all across Europe and as far as Siberia, and although we’ll never be able to ask their creators why they made them, we somehow still feel a connection with the stories they were trying to tell.
If He Seems Emotionally Unavailable, Look Again
By: The Good Men Project
Tags: Life Lessons, Emotional Intelligence, Vulnerability, Relationships, Love

I don’t know the real deal between the two of you in particular, but I can tell you what I’ve learned over the years from my work with couples. So many men seem emotionally unavailable to their partners. And here’s my take on why:

Men are not socialized to be in touch with their emotions.

This does not mean that they do not have emotions, but that many men are not terribly adept at “going there” and actually accessing them. Boys as early as 5 years old are told to be “big boys” and not cry. They become experts at turning their painful emotions off.

They may seem “emotionally limited” and indeed may have a hard time accessing their emotions, but the emotions are there. Your man has emotions. He just might need a little help getting to know them a little more.

There’s a constant pressure on men to be the best — to earn enough, to be tall enough, to be smart enough.

So many men just wind up feeling inadequate, and the message that they are okay just as they are doesn’t come through often enough. It’s not that he doesn’t want you to know about him. More likely he doesn’t think his emotional experience really matters, if he can even access it, and he’s probably learned that there’s really no point to it.

His world gets thrown upside when you’re dissatisfied with him, and the only thing he knows to do is either get defensive or shut off.

Men want to make their partners happy. Doesn’t everyone?

What he doesn’t realize is that you want him and his emotional presence and experience more than anything. When you’re not getting that, he just gets the message that he can’t get it right, so he feels hopeless and doesn’t even bother trying.

This, understandably, leaves you feeling more frustrated, abandoned and hopeless that he even has what it takes to be in a committed relationship. Sadly, so many women feel like their partners just don’t care enough about them, when in reality, I see men who are feeling so damaged and scared underneath a calm, cool exterior, who want more than anything to make their partners happy, they just don’t know how.

Often, when they try, they don’t get it right enough, and the message that they’re inadequate and unsatisfactory is reflected back to them.
Insolar Launches MainNet and New Native Token
By: Rochelle Guillou
Tags: Insolar, Daily Mover, Crypto, Business, Blockchain

INS FCAS is up 18.56% over the last two weeks. User Activity climbed 126-points (44.06%) and Developer Behavior ascended 65-points (9.98%). Price is up 18.75% over the same time period.

What is INS?

INS is the native token of the Insolar Blockchain Platform, an enterprise-focused blockchain that can be leveraged for both public and private solutions. The team’s unique approach to network consensus enables transactions to be executed by only one node, and validated by a subset of nodes, thus greatly improving scalability and speed.

It’s also important to note that all objects on the Insolar platform are in essence smart contracts. These smart contracts communicate with each other through messages, which makes the platform inherently interoperable with conventional systems and existing enterprise blockchain solutions such as Hyperledger Fabric.

Goodbye INS; Hello Brave New World

On February 3rd the Insolar team announced the launch of its MainNet, which spiked its User Activity up 126-points (44.06%), driving FCAS up 93-points (18.56%). Developer Behavior also went up 65-points (9.98%) as more code contributions came in. Key components of the Insolar MainNet include the Insolar Wallet, Insolar Explorer, and a secure, third-party audited architecture.

The Insolar MainNet also marks the debut of Insolar’s native coin, XNS, which will replace its longstanding ERC20 token, INS. This explains the drastic increase in User Activity we’re witnessing, which is likely to level-off as less holders of INS swap their tokens for XNS. This new native token will be used for on-chain payments, staking, and eventually decentralized governance of the network.

Our Hot Take

Insolar is actively breaking barriers to blockchain adoption by removing the need for enterprises to even understand what blockchain technology is — they just need to know what it does and the problems it solves. The network’s cloud based storage means business users can join without setting up their own node, buying computing power from providers via a capacity hardware marketplace.

This also reduces the cost of operation for businesses who no longer have to purchase and store expensive IT equipment to participate in the network. The team took two years to test its platform before MainNet launch, now revealing a clean and simple web interface for businesses to seamlessly scale their blockchain pilot programs without investing in people or infrastructure.
