Not Everyone Has An Internal Monologue

The Relentless Jeff Bezos

In the spring of 94 web usage was growing at 2300% a year. You have to keep in mind human beings aren’t good at understanding exponential growth; it’s just not something we see in our everyday life. But things don’t grow this fast outside of Petri dishes. It just doesn’t happen. When I saw this, I said, okay, what’s a business plan that might make sense in the context of that growth. I made a list of 20 different products that you might be able to sell online. I was looking for the first best product, and I chose books for lots of different reasons, but one primary reason. And that is that there are more items in the book space than there are items in any other category by far. There are over 3 million different books worldwide in all languages. The number two product category in that regard is music, and there are about 300,000 active music CDs. And when you have this huge catalog of products, you can build something online that you just can’t build any other way. The largest physical bookstores, the largest superstores, and these are huge stores, often converted from bowling alleys and movie theaters, can only carry about 175,000 titles. There are only a few that large. In our online catalog, we’re able to list over two and a half million different titles and give people access to those titles.
Being able to do something online that you can’t do in any other way is important. It’s all about the fundamental tenet of building any business, which is creating a value proposition for the customer, and online, especially three years ago, but even today and for the next several years, the value proposition that you have to build for customers is incredibly large. That’s because the web is a pain to use today! We’ve all experienced the modem hangups and the browsers crash — there are all sorts of inconveniences: websites are slow, modem speeds are slow. So if you’re going to get people to use a website in today’s environment, you have to offer them overwhelming compensation for this primitive infant technology. And I would claim that that compensation has to be so strong that it’s basically the same as saying, you can only do things online today that simply can’t be done any other way. And that’s why this huge number of products looked like a winning combination online. There’s no other way to have a two-and-a-half-million-title bookstore. You can’t do it in a physical store, but you also can’t do it in a print catalog. If you were to print the M’s on a card catalog, it would be the size of more than 40 New York city phone books.

Social Networking 2.0

It is always tricky to look at the analog world if you are trying to understand the digital one. When it comes to designing products, a pattern you see repeatedly is copying what came before, poorly, and only later creating something native to the medium.
Consider text: given that newspapers monetized by placing advertisements next to news stories, the first websites tried to monetize by — you guessed it — placing advertisements next to news stories. This worked, but not particularly well; publishers talked about print dollars and digital dimes, and later mobile pennies. Sure, the Internet drew attention, but it just didn’t monetize well.
What changed was the feed, something uniquely enabled by digital. Whereas a newspaper had to be defined up-front, such that it could be printed and distributed at scale, a feed is tailored to the individual in real-time — and so are the advertisements. Suddenly it was print that was worth pennies, while the Internet generally and mobile especially were worth more than newspapers ever were.
<...>Even that, though, suggests that the company can’t entirely escape its roots: having one identity is a core principle for Facebook, which is great for advertising if nothing else, but at odds with the desire of many to be different parts of themselves to different people in different contexts. Twitter, meanwhile, is unlikely to ever recover from its missed opportunity to dominate the interest graph.
Instead, the role for both products will be as a bridge between attention-focused products on one side, and private interest-defined trusted groups on the other. Their networks still have value, but primarily as a tool for distribution and reach of content that will increasingly be created in one place, and discussed in another.

Red Hat Goes Full IBM and Says Farewell to CentOS

The end of support for CentOS 6 was in November 2020. Since RHEL and CentOS are known for long support cycles, a lot of organizations decided to jump from CentOS 6 to 8 instead of re-platforming on 7 since that maximizes the time until another re-platforming effort would need to be scheduled. Or that is what many in the industry thought.
Then, on December 8, 2020, Red Hat announced that it was going to cut the current CentOS 8 support timeframe down considerably in the process of effectively killing the project. While 2021 may not be impacted, with CentOS 6 EOL on November 30, 2020, and CentOS 8 EOL on December 31, 2021, by January 1, 2022 CentOS 7 will be the only one receiving Maintenance Updates. The CentOS name will live on but in a different part of the ecosystem than it has to date.

Doing Business In Japan

Doing business with Japanese companies frequently resembles It’s A Wonderful Life. “Customer relationships” are not an empty phrase — many business relationships where one is approximately equivalent to a row in the database in the United States are, instead, expected to be relationships between two actual people.
This is occasionally exasperating, as a software person who doesn’t want to have to take someone drinking to sell a single SaaS account, but it is occasionally quite charming. Moving to Japan, particularly small-town Japan, was like visiting an old America that I had heard stories about but had never gotten the opportunity to experience.
For example, when I first came to Japan, I had no computer. I also had no money, because the plane ticket and setting up my household ate all of my savings. In America, this isn’t a barrier to getting a computer, because Dell will do a quick FICO score on you and then happily extend you $2,000 of trade credit.
Dell Japan, on the other hand, set me up with two phone calls with actual human underwriters at two Japanese financial institutions. Both had me fill out rather extensive forms (100+ questions — seriously). The first said “In view of your length of tenure at your employer and length of residence at your apartment, we don’t feel that your situation is stable enough to extend you credit.” The second said “Look, umm, officially, I am supposed to just tell you that we decline your business and wish you luck. Unofficially, the bank doesn’t extend foreigners credit, as a matter of policy. You’ll find that is quite common in Japan. I know, it is lamentable, but I figure that you’d be able to save yourself some time if you knew.”
So I gave up for a while, but mentioned to a coworker later that week that I really wanted a computer to be able to Skype home. He said “Come with me” and we left, in the middle of the work day, to visit a bank. It is a smaller regional bank in Gifu. I’ll elide naming it to avoid the following story being personally identifiable, but suffice it to say it is a very conservative institution.
My coworker got a credit card application and asked me to fill it in. I did so, but told him “Look, two Tokyo banks, which are presumably about as cosmopolitan as Japanese financial institutions get, just shot me down. One of them explicitly did so because I’m a foreigner. The chance of this middle-of-nowhere bank accepting a credit application is zero.”
“Don’t worry, I know the manager. Hey, Taro!”
Taro and my coworker had gone to school together.
“Patrick here just started working with us. He wants to buy a computer to call his parents, diligent son that he is, and needs a credit card to do it. Here’s his application. Make sure it doesn’t get lost in the shuffle, OK?”
Some weeks passed, and I assumed that I had been denied. Then there was a knock on my door early one Saturday morning.
It was bank manager Taro and an older gentleman who introduced himself as the Vice President for Risk Management of the bank. He promptly took over the conversation.
“You have to understand that we’re not one of those banks. We’re not some magical pot of money. Every yen we have is a farmer depositing against a bad harvest or a retiree’s pension, carefully husbanded over a lifetime. That is a sacred trust. We cannot lose their money. The bank has to be appropriately careful about who we lend that money to. Taro here tells me your trustworthy, so that is good. Even trustworthy young men sometimes make poor decisions. I need to know you won’t, so before I give this credit card, I have three questions for you.”
“Will you ever use this credit card to gamble?”
“No, sir.”
“Good. Will you ever use this credit card to buy alcohol?”
“No, sir.”
“Good. Will you ever give this credit card to a woman who is not your wife?”
“No, sir.”
“Good. Think darn hard before giving it to your wife, too. OK, you pass muster. Sign here.”
That was the first of a dozen stories which you wouldn’t believe actually happened about that bank. Taro correctly intuited when I started dating a young lady, and when we broke up, solely based on on my spending habits. He considered that part and parcel with looking out for my financial interests.
Taro stopped me from doing a wire transfer back to Bank of America to pay my student loans during the Lehman shock because Wachovia had gone into FDIC receivership that morning. I told Taro that I didn’t have an account at Wachovia. Taro said that he was aware of that, but that I used Lloyds’ remittance service to send wires, and Lloyds’ intermediary bank in the US was Wachovia, which might or might not be safe to have money in at the moment. I asked Taro how in God’s name does a banker in Ogaki, Japan happen to know what intermediary banks Lloyds uses in North America off the top of his head, and Taro said, and I quote, “There exists a customer of the bank who habitually makes USD wire transfers using Lloyds and, accordingly, it is my business to know this.”
Taro called me on March 12th, the day after the Touhoku earthquake, to say that he was concerned about my balance in the circumstances (I had cleared out my account to pay a tax assessment minutes before the quake) and, if I needed it, to come down to the bank and, quote, we’ll take care of you and worry about the numbers some other time, endquote.
Taro eventually retired from his position, and as part of making his rounds, gave me a warm introduction to the new bank manager. He made it a point to invite me out for coffee, so that he’d be able to put a face to Taro’s copious handwritten notes about my character. Some years after that, a new manager transferred in. I popped by with a congratulations-on-the-new-job gift, mildly surprising the staff, but it felt appropriate.
When I moved to Tokyo, I went to the regional bank’s sole Tokyo office, which exists to serve their large megacorp customers. They were quite shocked that I had an account with the bank (“Mister! Citibank is down the street! If you use our ATMs you’ll get charged extra!”), and even more shocked when I told them that I run a multinational software company through it. “Wouldn’t you get better services with Citibank or Mitsubishi?” The thought of switching never crossed my mind. Indeed, I can’t imagine anything that would convince me to switch. They don’t make numbers big enough to compensate for how much I trust my bank.
Was I a particularly large account to the bank? Nope. It’s the same passbook savings account a 17 year old gets to deposit their first wages into. For 8+ of my ten years in Japan, my balance there was below $2,000.
The bank is one anecdote, but I could tell you about the hair stylist who drops me a handwritten postcard after every appointment, the restaurant that I went to weekly that tried to cater my wedding for free, the glasses shop which invited me to come back for a (free) frame re-bending and cup of coffee any time I was in the neighborhood, etc etc.

Social cooling

  • Kai kurie žmonės jau yra linkę elgtis atsargiau internete ir skirti daugiau dėmesio privatumo aspektams. Tačiau visgi didžiajai daugumai visa tai ir toliau nerūpi arba jų argumentas susiveda į "koks skirtumas, aš neturiu ką slėpti". Viena iš problemų kodėl taip yra - nes pro-privacy argumentai apima daug visokių skirtingų aspektų ir implikacijų ir jie tampa tiesiog kompeksiški ir sunkiau suvokiami.
  • Manau šis saitas nors ir labai kriminalistikai, tačiau supaprastina viską iki labai paprastos ir aiškios "social cooling' koncepcijos.
If you feel you are being watched, you change your behavior. We are becoming too transparent. This is breeding a society where self-censorship and risk-aversion are the new normal. Privacy is the right to be imperfect

Ask HN: What is it like to be old? What advice would you give to younger people?

What's it like to be old? My boss is younger than I am and is absolutely sure he knows more about my job than I do, even though I've been doing it since before he was born and he never did it at all. People on TV keep trying to sell me stuff like Metamucil, some new kind of cane or similar silly gadget, or a scam investment, none of which I want. My grandkids can't understand why I can't read things they're holding right in front of my face until I've spent twenty minutes finding, then cleaning, my glasses. My wife has heard all of my jokes and all of my excuses. She now criticizes the former and laughs at the latter, instead of the other way around. My friends sound like cranky old sticks-in-the-mud who wish they could turn back the clock to a time that wasn't nearly as wonderful as they claim to remember it was. A trip to the supermarket now tires me out and instead of going out with (surviving) friends, I really look forward to taking a nap on the couch. Really. The celebrities I recognize are senile and/or decrepit. The ones who are currently popular are appalling. I don't have enough money to retire but dream of it every day (See the above comment about my boss). Life is fantastic, except when it's not. Whichever it is now, pretty soon, it will be the other one. My advice: Pay attention.
The key is finding a good balance between working hard and playing hard. Your career won't suffer if you take a week long vacation. Your health will be fine if you sometimes volunteer to do a weekend shift. Do both and you can be successful and happy about how you spent your youth.
My advice at mid-50s to younger people is to learn 1. manage your energy for your long term health, 2. enjoy time with the highest quality people you can find (I mean that in terms of good language, hopeful, constructive/collaborative in nature and working on themselves, empathetic to all those around you), and lastly say "yes" to almost everything and enjoy to the max. If my life were a candle, every year it is slowly losing some if its brightness/energy through no fault or effort on my own. I had an unusual situation which aged me faster than I ever wished for-- lost my mid-30s wife to a rare cancer 3 years after diagnosis. A part of me died with her and my heart will never heal. Still I wake up hopeful every day. We are all along for a short ride, enjoy the hell out of it. It could/will disappear in an instant.

There are “only two ways to make money in business: One is to bundle; the other is unbundle.”

Music was one of the things where there was this very clear set of bundles in which the products were sold. It was incredibly profitable for the big music companies and for a lot of the artists. And that got completely pulled apart. But now, we’re getting new sorts of bundling in there.
It’s an effective growth strategy. Once you try to grow the business, it’s an easier out to stay focused on your core and then add things to it. And you become a big bundle again. Which then creates a new vulnerability that you didn’t have when you were the insurgent.

The Truth Is Paywalled But The Lies Are Free

Samsung Galaxy S20 vs. iPhone 11 Pro: A deeper division lurks beneath the spec sheets

  • We've lately been of the mind that comparing Android and iOS phones primarily on a specs, benchmarks, or hardware basis is folly. Most informed buyers - choose between Android and iOS on the basis of software, services, and extremely divergent philosophies about openness, customization, and privacy.
  • It can be astonishing to see the amount of passion or even vitriol in Android vs. iOS discussions across social media and the Web—and by extension, Galaxy S vs. iPhone discussions, since those are the most popular devices to run those operating systems in most markets right now. Yes, this is partly because of highly charged marketing messaging by players in both platforms, tribalist tendencies in people, and the need to justify one's own choices, especially if those choices were costly.
  • But at the heart of things, this division is actually because the two platforms represent different world views on many questions about the relationships human beings should or shouldn't have with tech companies, app developers, and devices. When you look at it through that lens, it makes perfect sense that the arguments can be so emotionally charged.
  • That doesn't mean it's acceptable to be mean or toxic about these differences. It's important to have productive discussions about the issues at hand. But debates comparing the new Galaxy phone to the latest iPhone ultimately aren't really about the megapixels, and we all know it.

What Happened with LEGO

  • As I showed before, LEGO has had $100+ sets for a while. However, only recently have they produced sets even more pricy than that. When we were kids, the $100 set was the pinnacle of LEGO. It was the set we all aspired to own. It was the set we all went straight to at the store. Of course we rarely ended up with that set, but that was our dream.
  • Now, the dream set is closer to the $400 range. It doesn’t mean that LEGO doesn’t make sub-$100 sets. They do, and more than ever. It just means that in comparison the $25 set looks a lot smaller than it did when the largest set was only $100. LEGO pricing has become a victim of its own expanding market.

The Apple Watch, Five Years In

  • Switzerland fought the war against quartz, and guess what, they lost" – and that is a great thing. That meant that the thriving mechanical watch industry of today occupied and continues to occupy an even more precious place in the world – that of the superfluous, but beautiful. The people that read our site for detailed images of A. Lange & Sohne chronographs and Vacheron Constantin tourbillons don't need these objects to tell the time – that’s already been taken care of. They are here to simply sit back and appreciate something that the world doesn’t need anymore.

News in the age of abundance

  • Both cereal and the daily news began as well-intentioned efforts to improve American lives. But just as cereal turned into sugar for the body, news turned into sugar for the mind.
  • Newspapers have folded under the weight of rising competition and falling advertising revenues. To save their businesses, they’ve pivoted from the expensive work of reporting and relied more on cheap tricks like turning tweets and press releases into articles.
  • Writers who want to attract an audience for their ideas have an incentive to stretch or distort facts to give them a compelling narrative arc. In doing so, some journalists omit important details, conflate fact with opinion, and change the meaning of the story.
  • Professionals are outfoxed at every turn by citizen journalists on Youtube, Periscope, and Twitter who are simply savvier, less constrained, more authentic, and less wooden.
  • Words don’t just explain the world. They change how we feel about it.
  • Out of all the money spent on advertising in America, roughly 40% of it goes to television. Even in the age of the Internet, television has kept its grip over American life by changing its product in response to the explosion of the image.
  • In media theory, the “Overton Window” is defined as the range of acceptable opinions in a society. It’s an invisible cognitive prison. Anything inside the window is fair game, but stretch beyond its borders in polite company and you’ll turn heads or be ostracized from conventional social groups.
  • The smart way to keep people passive and obedient is to strictly limit the spectrum of acceptable opinion but allow very lively debate within that spectrum….
  • When media moves from text to images, societies start to worship glamour over truth, emotion over rationality, and youth over wisdom.
  • By encouraging image-based communication, television changed how we think. It paved the way for a dictatorship of the eye over the mind, which creates an emotionally turbulent world which prized looks over logic and passion over reason. It deluded people into thinking the world could be summarized in small nuggets of pre-packaged information. In response, people outsourced their thinking to multinational media companies who “keep them informed.”
  • In the trade-off between entertainment and education, entertainment will always have the final word.
  • Through billboards and banner ads, companies engineer problems so their products can solve them. For example, bad breath wasn’t a problem people discussed until advertising campaigns in the early 20th century invented the problem and swooped in to solve it with products such as toothpaste and mouthwash.
  • Advertisers are applied psychologists. Instead of selling products, they tell people that by buying their products, they will become better versions of themselves. Advertisers know it’s better for their products to be misunderstood than ignored, so they capture consumer attention by focusing on the emotional benefits of purchasing a product instead of using facts, figures, and statistics that most people will ignore.
  • Online publications compete to get stories first, newspapers compete to 'confirm' it, and then pundits compete for airtime to opine on it. The smaller sites legitimize the newsworthiness of the story for the sites with bigger audiences. Consecutively and concurrently, this pattern inherently distorts and exaggerates whatever they cover.
  • Bloggers increasingly write with the authority of a news publication but envy the credibility of journalists. Meanwhile, journalists increasingly write with the speed of the blogosphere but envy the independence of bloggers.
  • In my experience, people who say everybody should pay for news spend most of their time with people who also pay for news, so they overestimate people’s appetite for paywalled information.
  • Subscription publications will reinforce their readers’ perspectives because most people only pay for information they agree with. Thus, an increase in subscription-supported media won’t just fragment information sources. It will fragment society.
  • Obsessive news consumption leads to a negativity bias that distorts our worldviews because creation happens slowly, but destruction happens fast and seizes our attention. Therefore, the kind of rare events that jump to the front pages of the newspaper tend to be negative, while stories about steadily declining poverty rates or improvements in global health rarely make national headlines.
  • It's not the media's role to present the world as it really is. They (media) will always have to compete to engage our attention with exciting stories and dramatic narratives. It is upon us consumers to realize that news is not very useful for understanding the world.
  • The current philosophy is built upon the fundamental lie that news is worthy of consuming every day. Daily news is profitable because it’s an unnecessary habit. Just like cereal, once people make a habit of eating it during their morning routine, they tend to maintain the habit.
  • When we direct our attention to the daily shouts of breaking news, we overwhelm ourselves with irrelevant data and uncommon events. We give rare events too much publicity, which distorts our model of the world. In turn, we mistake chance for certainty and the infrequent for the inevitable. Instead of enriching ourselves with the wisdom of history, we drive ourselves insane with the madness of the moment.
  • The best lack all conviction, while the worst are full of passionate intensity.
  • One of the biggest benefits of writing online is realizing how often I'm wrong about the world. Whenever I publish an essay, I’m surprised by how many people respond with well-reasoned rebuttals I’ve never considered. As the responses have increased, I’ve been humbled by my inability to predict the future
  • No human will ever be able to understand the world. It’s too complex, and we can’t see culture because we’re overwhelmed by its invisible influences. At best, we can build local expertise and useful — but ultimately inaccurate — models of the world. Past a certain point, additional information deludes us because it makes us think we understand the world more than we actually do.
      • The benefits of the Internet are only as strong as your ability to direct your attention. It’s a gift to people with self-control, but a curse to those without it. And while it hurts the average news consumer, savvy ones have never been smarter or more informed.
      • Fathers and mothers have lost the idea that the highest aspiration they might have for their children is for them to be wise — as priests, prophets or philosophers are wise. Specialized competence and success are all that they can imagine.
      • People are expected to have an opinion on every story, but even the experts don’t have enough time in the day to familiarize themselves with every aspect of every story. Without the time to research what we read, we confuse what’s true with what feels right.
      • So skip the news cycle, but double-down on measured consumption. Ignore society’s recommendations for what to consume and refresh your learning habits like you’re shaking an etch-a-sketch. Remember, what you should consume looks nothing like what you were taught to consume, so rebel against the mainstream spotlight, find some trusted curators, chart your own path instead.
  • On the Internet, your rate of learning is limited not by access to information, but by the discipline to ignore distractions.

Staying Motivated by Sending Status Updates to Nobody

  • Kai kurios komandos Google viduje naudoja vidinį įrankį pavadinimu Snippets. Konceptas gan paprastas - tai tiesiog tekstinis laukas, kuriame užpildomi savaitės pasiekimai. Sekančios savaitės pradžioje manageris ir kiti komandos nariai gauna email suvestinę.
  • Principas atrodytų labai paprastas, tačiau jis pasiekia porą gan įdomių tikslų: pirmiausia meet'u metu nebereikia gaišti laiko status update'ams ir galima fokusuotis į kur kas mažiau nuobodžias temas, kaip kad techninės problemos ir jų sprendimo būdai. O taipogi tai padeda objektyviai įvertinti kas iš tiesų buvo pasiektą per savaitę. Kartais, kai praleidi visą savaitę medžiojant vieną bug'ą, atrodo kad visa savaitė tiesiog sudegė ir nieko taip ir nenuveikei, nors iš tiesų vis vien pasiektas koks nors progresas - pvz giliau susipažinta su sistemos veikimu ir atrasti edge case'ai ar pataisyti keli naujai atrasti bug'ai, patikslinta dokumentacija ar patobulinti automatiniai testai.
  • Nors tokia praktika, jog ji priliptų ir nebūtų numetama reikalauja fokuso ir disciplinos, tačiau nedarant tokių retrospektyvų dažniausiai dalį savaitės pasiekimų tiesiog užmiršti ir labiau prisimeni tai, ko nebespėjai padaryti per savaitę.

The diamond invention

  • Tikriausiai visi esame susidūrę su požiūriu ar ir patys jį propaguojame, jog deimantai iš tiesų nėra jau tokie vertingi, jog visa ši industrija iš esmės yra kartelinis susitarimas, kuris laiko dirbtinai išpūstas kainas.
  • Dar 82-aisiais The Atlantic paskelbė išties ilgą, tačiau puikią publikaciją, kurioje itin detaliai ir nuodugniai aprašoma kaip buvo sukurta visa ši deimantų rinka. Pradedant nuo to, kaip atradus milžiniškus deimantų šaltinius Pietų Afrikoje ir pradėjus juos kasti tonomis, buvo sukurta schema, užtikrinanti, jog tai netaptų dar viena commodity preke, apie tai, kaip po didžiosios depresijos ir I pasaulinio karo pardavimai nusirito žemyn ir kaip pasitelkus vieną lyderiaujančių JAV reklamos agentūrų, buvo sukurta pati sėkmingiausia reklaminė kampanija istorijoje, kurios metu buvo atrastas influencerių marketingas. Na ir baigiant tuo, kaip yra kontroliuojama antrinė rinka, sudaromas įspūdis, jog deimantai negali nuvertėti ir jų kaina nuolatos kyla ir galiausiai, kaip ši sužadėtuvių tradicija įskiepyta net Japonijoje - šalyje, kuri turi itin gilias tūkstantametes tradicijas.
The diamond invention is far more than a monopoly for fixing diamond prices; it is a mechanism for converting tiny crystals of carbon into universally recognized tokens of wealth, power, and romance.
N. W. Ayer suggested that through a well-orchestrated advertising and public-relations campaign it could have a significant impact on the "social attitudes of the public at large and thereby channel American spending toward larger and more expensive diamonds instead of "competitive luxuries." Specifically, the Ayer study stressed the need to strengthen the association in the public's mind of diamonds with romance. Since "young men buy over 90% of all engagement rings" it would be crucial to inculcate in them the idea that diamonds were a gift of love: the larger and finer the diamond, the greater the expression of love. Similarly, young women had to be encouraged to view diamonds as an integral part of any romantic courtship.
Since the Ayer plan to romanticize diamonds required subtly altering the public's picture of the way a man courts -- and wins -- a woman, the advertising agency strongly suggested exploiting the relatively new medium of motion pictures. Movie idols, the paragons of romance for the mass audience, would be given diamonds to use as their symbols of indestructible love. In addition, the agency suggested offering stories and society photographs to selected magazines and newspapers which would reinforce the link between diamonds and romance. Stories would stress the size of diamonds that celebrities presented to their loved ones, and photographs would conspicuously show the glittering stone on the hand of a well-known woman.
In addition to putting these plans into action, N. W. Ayer placed a series of lush four-color advertisements in magazines that were presumed to mold elite opinion, featuring reproductions of famous paintings by such artists as Picasso, Derain, Dali, and Dufy. The advertisements were intended to convey the idea that diamonds, like paintings, were unique works of art.
By 1941, The advertising agency reported to its client that it had already achieved impressive results in its campaign. The sale of diamonds had increased by 55 percent in the United States since 1938, reversing the previous downward trend in retail sales. N. W. Ayer noted also that its campaign had required "the conception of a new form of advertising which has been widely imitated ever since. There was no direct sale to be made. There was no brand name to be impressed on the public mind. There was simply an idea -- the eternal emotional value surrounding the diamond."
In its 1947 strategy plan, the advertising agency strongly emphasized a psychological approach. "We are dealing with a problem in mass psychology. We seek to ... strengthen the tradition of the diamond engagement ring -- to make it a psychological necessity capable of competing successfully at the retail level with utility goods and services...."
The idea was to create prestigious "role models" for the poorer middle-class wage-earners. The advertising agency explained, in its 1948 strategy paper, "We spread the word of diamonds worn by stars of screen and stage, by wives and daughters of political leaders, by any woman who can make the grocer's wife and the mechanic's sweetheart say 'I wish I had what she has.'"
De Beers needed a slogan for diamonds that expressed both the theme of romance and legitimacy. An N. W. Ayer copywriter came up with the caption "A Diamond Is Forever," which was scrawled on the bottom of a picture of two young lovers on a honeymoon. Even though diamonds can in fact be shattered, chipped, discolored, or incinerated to ash, the concept of eternity perfectly captured the magical qualities that the advertising agency wanted to attribute to diamonds.
Toward the end of the 1950s, N. W. Ayer reported to De Beers that twenty years of advertisements and publicity had had a pronounced effect on the American psyche. "Since 1939 an entirely new generation of young people has grown to marriageable age," it said. "To this new generation a diamond ring is considered a necessity to engagements by virtually everyone." The message had been so successfully impressed on the minds of this generation that those who could not afford to buy a diamond at the time of their marriage would "defer the purchase" rather than forgo it.

Should the Rich Be Allowed to Buy the Best Genes?

  • Galima gan nesunkiai įžvelgti panašumų tarp to kur buvo IT pasaulis maždaug 1970-aisiais ir tarp to, kur yra šiuo metu genų inžinerija. Ir nors dabar pirmosios kalbos sukasi daugiau apie ydų, kaip genetinių mutacijų ar ligų šalinimą, tačiau riba visgi yra labai slidi. Pvz nutukimo potencialo šalinimas dar genų lygmenyje - tai būtų gydymas ar visgi labiau panašu į genetinį patobulinimą? Akivaizdu, kad šiai sričiai tobulėjant ir išmokus susitvarkyti su pagrindinėmis problemomis, ties tuo tikrai nesustosime. Problema galbūt yra tai, kad išties dar ilgą laiko tarpą tokia galimybė potencialiai save pasitobulinti bus prieinama tik labai mažam, privilegijuotų žmonių tarpui ir net jei jų šalyje galimybės ir būtų apribotos, tačiau yra išties labai sunku reguliuoti, standartizuoti tokius dalykus ir skirtingos šalys įsiveda visiškai skirtingus reguliavimus, tad netruktų atsirasti ir genetinis turizmas.


  • Programėlė pirmą kartą viral patapo dar 2017-ais ir būtent tada ją teko išbandyti ir man. Pamenu, pasijuokiau, kad pasendinus patalpintą nuotrauką, joje atrodau išties panašiai į savo senelį. Tačiau banga kaip staiga uždėjo, taip ir praėjo. Tada atėjo 2019-tų vasara ir prasidėjo antroji ir šį kartą kur kas stipresnė banga. Pirmiausia vajus įsisiubavo po to, kai programėle pasinaudojo kelios pasaulio įžymybės ir populiarumas išaugo iki tiek, jog atrodo, kad ja pasinaudojo ko ne visi, kas tik naudojasi socialiniais tinklais. Tačiau net nespėjus tai bangai nuslūgti, prasidėjo antrasis vajus, tik šį kartą sėjantis paniką ir pasipiktinimą. O tai kilo dėl to, jog į viešumą iškilo faktas, kad app'są sukūrė Rusijos IT kompanija bei tai, kiek milijonų žmonių jau spėjo jiems atiduoti savo duomenis ir galiausiai tai, kad jų licencija yra labai plataus pobūdžio ir iš esmės leidžianti naudoti surinktą informaciją bet kokiems tikslams. Ir taip, aš pilnai suprantu susirūpinimą dėl privatumo (vieta iš priežasčių, kodėl Facebook'e aš nesu užsivadinęs savo tikru vardu ar pavarde jau daugybę metų), bet iš kitos pusės, pirmiausia manau, kad skandalas išsipūtė vien jau dėlto, jog tai rusų apps'as. Taipogi, žmonės savo nuotraukas talpina į bet kokias random programėles, o tada mąsiškai "susirūpina" savo privatumu ir skundžiasi Facebook komentaruose, kuris juo labiau garsėja savo privatumo pažeidimais, kurie yra kur kas didesnio masto, o savo licencijoje irgi turi labai panašių punktų apie tai, kaip gali būti naudojama patalpinta vartotojų informacija. Visa tai yra tiesiog hipokritiška. Tie žmonės, kuriems iš tiesų tai rūpi, jie savo privatumu rūpinasi jau senai, o kiti puolė į masinę isteriją tiesiog dėl herd mentality. Keli straipsniai ta tema:

Xbox hakerių grupuotė

  • Nemažas tačiau išties įdomus editorial'as apie paauglius Xbox hakerius. Smalsumas ir smulkios žaidimų žemėlapių vagystės virto į stambaus masto įsilaužimus, o patraukus jau ir FBI dėmesį, istorija baigėsi kalėjimais, darbo pasiūlymais ir mirtimi.

Senoliai nusikaltėliai

  • Turėdavau tokią mintį, kad jei esi benamis, ko gero turėtų būti didelė paskata tiesiog elementariai vogti. Nekalbu apie dideles vagystes, kaip kad automobiliai ar kitas brangus turtas kur rizika ir pasekmės galėtų būti dideli. Labiau apie nedideles vagystes, kaip pvz maisto produktai iš parduotuvės. Jei pavyksta - ok, turėsi ką pavalgyti. Nepavyksta ir pagauna - nuveš ir palaikys areštinėje, turėsi bent laikinai stogą virš galvos, bus šilta (labai aktualu gi žiemą), o jei užlaikytų ilgiau - tai dar ir pavalgyti gausi. Praktiškai win-win situacija.
  • Nesu tikras, kaip su šia logika yra mūsų šalyje, bet kai kur toks principas iš tiesų veikia. Vienas iš pvz yra Japonija, kuri ir taip turi gan stiprią senėjančios demografijos, mažo gimstamumo, vis labiau užsidarančios visuomenės problemas. Jei neturi artimųjų, kurie padėtų ir pasirūpintų, o pasiekus pensijinį amžių iš bazinės pensijos šalyje nepragyvenama, tai nieko kito nebelieka kaip bandyti vagiliauti. Tad nenuostabu, kad senolių nusikaltėlių lygis šalyje auga jau paskutinius 20 metų. Įdomus ir kiek netikėtas aspektas yra tai, kad pensija būnant kalėjime tai vis vien yra mokama. Tad padarai nedidelį ne smurtinį nusikaltimą, pasėdi kalėjime metus ir išeini jau susitaupęs ir bent jau kurį laiką turi iš ko pragyventi.

Computational photography

  • Long grid'as apie visus pagrindinius computational photography principus. Kitaip tariant, papasakojama kodėl nuotraukos vis gerėja, nors objektyviai iš esmės smarkiai nesikeičia ir apie tai, kad visos esminės fotografijos inovacijos pastaruosius 10 metų vyksta būtent dėka mobiliųjų įrenginių.

I charged $18,000 for a Static HTML Page

  • Istorija, labai puikiai parodanti kokie gremėzdiški ir darbų atžvilgių neefektyvūs gali būti korporatyvai. Tikri laiko siurbikai ir jis deginamas daugybėje susitikimų, laukime ir begalėje elektroninių laiškų. Skaitant kitų industrijoje dirbančių žmonių reakcijas į šį straipsnį, galima nesunkiai suprasti, kad tai toli gražu nėra vienetinis atvejis ir tokios ir panašios istorijos ištiesų nutinka nuolat.

Andy Weir - Digitocracy #shortstory

  • The Martian autoriaus trumputė istorija apie dirbtinį intelektą, valdantį miestus. Kartais morališkai drastiškais būdais, tačiau visgi pasiekianti teigiamus rezultatus. Ar sutiktumei gyventi tarsi mašinos prižiūrimu gyvunėliu, kuriam realiai yra apribotos teisės, tačiau to kaip ir nepajauti ir visgi gyvenimas nuo to mažai corrupt, našesnis, geresnis ir jautiesi laimingesnis.
