in praise of mediocrity

But there’s a deeper reason, I’ve come to think, that so many people don’t have hobbies: We’re afraid of being bad at them. Or rather, we are intimidated by the expectation — itself a hallmark of our intensely public, performative age — that we must actually be skilled at what we do in our free time. Our “hobbies,” if that’s even the word for them anymore, have become too serious, too demanding, too much an occasion to become anxious about whether you are really the person you claim to be.

If you’re a jogger, it is no longer enough to cruise around the block; you’re training for the next marathon. If you’re a painter, you are no longer passing a pleasant afternoon, just you, your watercolors and your water lilies; you are trying to land a gallery show or at least garner a respectable social media following. When your identity is linked to your hobby — you’re a yogi, a surfer, a rock climber — you’d better be good at it, or else who are you?

Zajtra ráno prednášam informatikom o konečných stavových automatoch a Turingových strojich. Pri tej príležitosti

It’s rare for a CS major to graduate without getting a healthy dose of NP-completeness and Turing machines, two beautiful areas of theory that would be enjoyable if they didn’t end up creating bad instincts. One biologist asked me to solve a problem in DNA sequence matching and I came back to him with the claim that it was NP-complete, a class of problems that can take a very long time to solve. He didn’t care. He needed to solve it anyway. And it turns out that most NP-complete problems are pretty easy to solve most of the time. There are just a few pathological instances that gum up our algorithms. But theoreticians are obsessed with the thin set that confound the simple algorithms, despite being rarely observed in everyday life.

The same problem happens with Turing machines. Dutiful CS students learn nihilistic results like Rice’s Theorem, which shows that we really can’t analyze computer algorithms at all. But Turing machines are a pretty bad model for how our regular machines operate and it’s often very easy to create software that does smart things with our code. Any CS major who doesn’t take these theoretical results with a healthy dose of salt risks giving up when a perfectly usable answer is close at hand.

The radical moral implications of luck in human life

It’s not difficult to see why many people take offense when reminded of their luck, especially those who have received the most. Allowing for luck can dent our self-conception. It can diminish our sense of control. It opens up all kinds of uncomfortable questions about obligations to other, less fortunate people. Nonetheless, this is a battle that cannot be bypassed. There can be no ceasefire. Individually, coming to terms with luck is the secular equivalent of religious awakening, the first step in building any coherent universalist moral perspective.

Lego Wants to Completely Remake Its Toy Bricks

It wants to eliminate its dependence on petroleum-based plastics, and build its toys entirely from plant-based or recycled materials by 2030. The challenge is designing blocks that click together yet separate easily, retain bright colors, and survive the rigors of being put through a laundry load, or the weight of an unknowing parent’s foot. In essence, the company wants to switch the ingredients, but keep the product exactly the same.

Na ministerstvo vnitra míří i Tibor Gašpar, policejní prezident, který byl nucen na nátlak veřejnosti odstoupit. Stal se poradcem slovenské ministryně vnitra Denisy Sakové (SMER – sociálna demokracia). A aby toho nebylo málo, Gašpar se stal poradcem i českého ministra vnitra za sociální demokracii Jana Hamáčka. Protože SMER se vždycky dokázal postarat o „Svoje lidi“. A „Naši lidé“ na oplátku konají, když nemají, a nekonají, když mají.

True, it’s often difficult for customers to articulate what they want. But what’s missed is that they’re often much better at pinpointing what they don’t want or like. What you should hear when customers say they want a faster horse is not the literal but instead that they find travel by horse to be too slow. The savvy product person can generalize that to the broader need of traveling more quickly, and that problem can be solved any number of ways that don’t involve cloning Secretariat or shooting their current horse up with steroids.

Porušili ste všetky moje práva, píše režisérka filmu o pôrodoch riaditeľovi nemocnice

Nespravodlivé je to, že Vaši zamestnanci a zamestnankyne porušili všetky moje práva, ako rodiacej ženy aj ako filmárky. Nebudem analyzovať, akým spôsobom sa v jednej z Vašich pôrodníc narodila naša dcéra. S následkami neprofesionality zdravotníckeho personálu sa vyrovnávame dodnes, rovnako ako tisíce ďalších rodín.

Nefér je tiež to, ako ma Vaši zamestnanci verejne osočovali, ako o mne klamali (prof. Borovský, Antolská), ako mi prehľadávali facebookový profil a vysmievali sa našim protagonistkám (doc. Záhumenský, Ružinov) alebo ako na tlačovej konferencii zneužili moju zdravotnú dokumentáciu (doc. Rusňák, Kramáre). Nezaslúžila som si ani vyhrážky konkrétnych pôrodníkov, ktoré sa ani neobťažovali posielať anonymne. Film síce vznikol za bývalého riaditeľa, ale toto všetko sa udialo pod Vaším vedením.

How to Pick a Career (That Actually Fits You)

For most of us, a career (including ancillary career time, like time spent commuting and thinking about your work) will eat up somewhere between 50,000 and 150,000 hours. At the moment, a long human life runs at about 750,000 hours. When you subtract childhood (~175,000 hours) and the portion of your adult life you’ll spend sleeping, eating, exercising, and otherwise taking care of the human pet you live in, along with errands and general life upkeep (~325,000 hours), you’re left with 250,000 “meaningful adult hours”. So a typical career will take up somewhere between 20% and 60% of your meaningful adult time.

starší rozhovor s N. K. Jemisin, od ktorej teraz čítam druhú knihu (prvá bola táto)

“As a black woman,” Jemisin tells me, “I have no particular interest in maintaining the status quo. Why would I? The status quo is harmful, the status quo is significantly racist and sexist and a whole bunch of other things that I think need to change.”

o meteorite, ktorý vyhubil dinosaury (z tejto knihy):

“The meteorite itself was so massive that it didn’t notice any atmosphere whatsoever,” said Rebolledo. “It was traveling 20 to 40 kilometers per second, 10 kilometers — probably 14 kilometers — wide, pushing the atmosphere and building such incredible pressure that the ocean in front of it just went away.”

These numbers are precise without usefully conveying the scale of the calamity. What they mean is that a rock larger than Mount Everest hit planet Earth traveling twenty times faster than a bullet. This is so fast that it would have traversed the distance from the cruising altitude of a 747 to the ground in 0.3 seconds. The asteroid itself was so large that, even at the moment of impact, the top of it might have still towered more than a mile above the cruising altitude of a 747. In its nearly instantaneous descent, it compressed the air below it so violently that it briefly became several times hotter than the surface of the sun.

“The pressure of the atmosphere in front of the asteroid started excavating the crater before it even got there,” Rebolledo said. “Then when the meteorite touched ground zero, it was totally intact. It was so massive that the atmosphere didn’t even make a scratch on it.”

Unlike the typical Hollywood CGI depictions of asteroid impacts, where an extraterrestrial charcoal briquette gently smolders across the sky, in the Yucatan it would have been a pleasant day one second and the world was already over by the next. As the asteroid collided with the earth, in the sky above it where there should have been air, the rock had punched a hole of outer space vacuum in the atmosphere. As the heavens rushed in to close this hole, enormous volumes of earth were expelled into orbit and beyond — all within a second or two of impact.

Ministerstvo školstva, vedy, výskumu, športu a stravovania

Cena je pomerne ľahko odhadnuteľná. Ide o dotáciu 1,20 eura na každý obed pre približne pol milióna detí, pričom teraz už štát platí obedy asi desatine detí. Navyše to teda bude v porovnaní so súčasnosťou stáť 100 miliónov eur ročne.

To je až pätina súčasných výdavkov na základné školstvo, čiže by šlo o dramatický skok o sumu, ktorá by napríklad na dlhé roky vyriešila debatu o nízkych platoch učiteľov. Nečudujme sa preto, že nielen v bohatších regiónoch sa mnohí riaditelia škôl pýtajú, či by sa peniaze na obedy zadarmo nedali využiť v školstve inak.

Môžeme sa len domnievať, že to bol bok niekoho zo samotného ministerstva, keďže na tabuľke, či neexistujúcej analýze pracovalo. Už je to aj tak jedno. Ministerstvo tabuľku, teda vlastne analýzu stiahlo. Prečo? Lebo podľa ministerky nechcelo plytvať verejnosťou. Nie. Nemám tam chybu. Plytvať verejnosťou!

Interrupcie nie sú o svedomí alebo náboženstve, ale o právach žien

Slovenské ženy nie sú nezodpovedné a sebecké, ako sa nás snažia presvedčiť naši protiinterrupční populisti.  V roku 2017 bolo vykonaných  6 102  umelých prerušení tehotenstva, čo je oproti 47 901 v roku 1990 pokles o viac ako 87 %, čo je jeden z najpozitívnejších trendov v Európe. Stalo sa tak predovšetkým vďaka osvete o plánovaní rodičovstva, používaniu antikoncepcie a sexuálnej výchovy. Aj rozdeľovanie žien na tie „dobré“, ktoré rodia deti a tie „sebecké a zlé“, ktoré chodia na interrupcie, je nezmyslom. Sú to tie isté ženy, len majú deti v iných obdobiach svojho života – vtedy, keď sa pre ne zodpovedne rozhodnú.

Nič tak neovplyvní život ženy ako dieťa. Nielen na deväť mesiacov. Na celý jej život.  Ak teda ona nesie zodpovednosť a následky, nesmie jej byť odňaté ani právo rozhodovať.

ako začať minimalizovať odpad

Úplne prvý krok je nosiť si so sebou plátenú tašku. Ja ich mám asi šesť až osem. Už som si tak odvykla od igelitiek, že aj keď si medzi kamarátkami posúvame detské veci, dávame ich aj s taškou. Dve mám v taške od kočíka, jednu v kabelke a jednu v ruksaku. Ak ich mám viac, nemusím sa na ne sústrediť. Odvykla som si úplne aj od mikroténových vreciek. Mám výbavu plátených. Na zeleninu, ovocie, chlieb a pečivo. Minule môj manžel doniesol asi po trištvrte roku domov mikroténové vrecko, zdalo sa nám to divné.

Are Kids the Enemy of Writing?

Writing was a practice. The more you wrote, the better a writer you became and the more books you produced. Excellence plus productivity, that was the formula for sustained success, and time was the coefficient of both. Children, the great man said, were notorious thieves of time. Then there was the question of subject matter, settings, experiences; books were hungry things, and if you stayed too long in any one place, they would consume everything and everyone around you.

pretože (tento článkok sa volá What Do We Do with the Art of Monstrous Men? a je v ňom ešte kopa iných vecí)

There are many qualities one must possess to be a working writer or artist. Talent, brains, tenacity. Wealthy parents are good. You should definitely try to have those. But first among equals, when it comes to necessary ingredients, is selfishness. A book is made out of small selfishnesses. The selfishness of shutting the door against your family. The selfishness of ignoring the pram in the hall. The selfishness of forgetting the real world to create a new one. The selfishness of stealing stories from real people. The selfishness of saving the best of yourself for that blank-faced anonymous paramour, the reader. The selfishness that comes from simply saying what you have to say.

Moms don’t need more mugs and wine glasses – neskoro, ale aj tak:

And there you have it, what moms would love on the big day: Get out of her hair (if the kids are little), spend time with her (if you’re a teen, but be sure to smile), and track her down in Greece (if you’re an adult). Moms are forged through the bubbling lava of no sleep, kindergarten graduations, slammed doors and 2 a.m. calls that begin, “I crashed the car, but I’m okay.”

planet or plastic?

Because plastic wasn’t invented until the late 19th century, and production really only took off around 1950, we have a mere 9.2 billion tons of the stuff to deal with. Of that, more than 6.9 billion tons have become waste. And of that waste, a staggering 6.3 billion tons never made it to a recycling bin.

Brandi Carlile: The Mother

Welcome to the end of being alone inside your mind
Tethered to another and you’re worried all the time
You always knew the melody but you never heard it rhyme

She’s fair and she is quiet, Lord, she doesn’t look like me
She made me love the morning, she’s a holiday at sea
The New York streets are as busy as they always used to be
But I am the mother of Evangeline

The first things that she took from me were selfishness and sleep
She broke a thousand heirlooms I was never meant to keep
She filled my life with color, cancelled plans and trashed my car
But none of that is ever who we are

Outside of my windows are the mountains and the snow
I hold you while you’re sleeping and I wish that I could go
All my rowdy friends around accomplishing their dreams
But I am the mother of Evangeline

They’ve still got their morning paper and their coffee and their time
They still enjoy their evenings with the skeptics and their wine
Oh but all the wonders I have seen I will see a second time
From inside of the ages through your eyes

You were not an accident where no one thought it through
The world has stood against us, made us mean to fight for you
And when we chose your name we knew that you’d fight the power, too

You’re nothing short of magical and beautiful to me
I would never hit the big time without you
So they can keep their treasure and their ties to the machine
Cause I am the mother of Evangeline

They can keep their treasure and their ties to the machine
Cause I am the mother of Evangeline

Brandi Carlile: The Joke

You’re feeling nervous, aren’t you, boy?
With your quiet voice and impeccable style
Don’t ever let them steal your joy
And your gentle ways, to keep ’em from running wild
They can kick dirt in your face
Dress you down, and tell you that your place
Is in the middle, when they hate the way you shine
I see you tugging on your shirt
Trying to hide inside of it and hide how much it hurts

Let ’em laugh while they can
Let ’em spin, let ’em scatter in the wind
I have been to the movies,
I’ve seen how it ends
And the joke’s on them

You get discouraged, don’t you, girl?
It’s your brother’s world for a while longer
We gotta dance with the devil on a river
To beat the stream
Call it living the dream, call it kicking the ladder
They come to kick dirt in your face
To call you weak and then displace you
After carrying your baby on your back across the desert
I saw your eyes behind your hair
And you’re looking tired, but you don’t look scared

Let ’em laugh while they can
Let ’em spin, let ’em scatter in the wind
I have been to the movies,
I’ve seen how it ends
And the joke’s on them

Let ’em laugh while they can
Let ’em spin, let ’em scatter in the wind
I have been to the movies,
I’ve seen how it ends
And the joke’s on them

Stephen Hawking dies at 76; His mind roamed the cosmos

Overlooked

Obituary writing is more about life than death: the last word, a testament to a human contribution.

Yet who gets remembered — and how — inherently involves judgment. To look back at the obituary archives can, therefore, be a stark lesson in how society valued various achievements and achievers.

Since 1851, The New York Times has published thousands of obituaries: of heads of state, opera singers, the inventor of Stove Top stuffing and the namer of the Slinky. The vast majority chronicled the lives of men, mostly white ones; even in the last two years, just over one in five of our subjects were female.

Picture a leader. Is she a woman?

“People have these prototypes in their head about what a leader looks like,” Dr. McClean said. “When we see an individual, we ask, ‘Do they fit that?’” If they don’t — even if they are acting like a leader — it’s harder to identify them as one. This disconnect does not require assuming that “women are less competent than men in general (e.g., intelligent, smart, organized, levelheaded),”
