Your unit tests only prove that your code does what you think it does. It doesn’t prove that your code does what it should be doing.

According to Sandi Metz: Duplication is better than the wrong abstraction. There is a paradox in software design titled "Use-Reuse Paradox": What's easy to use is hard to reuse. What's easy to reuse is hard to use.

As developers, it’s important to question what truly matters when it comes to the products we build. Marginal technical improvements may feel “more right” and even save a couple of clock cycles, but are they meaningful? Are they worth the time you might invest to achieve them? The answer lies in a very simple question we forget to ask ourselves far too often: “Does this help the user?” You’re not writing code to impress other programmers; you’re writing programs to give users the tools they need to do something.

Most people know so little that if they were transported 200 years into the past, they wouldn't be able to invent anything any quicker --r/Showerthoughts

One of the tingly bits about saving the instance of a Class is serializing. For those who don’t know what the hell is this, the concept is very simple: you can represent an instance of a class as a string, so you can store anywhere, and then restore the instance from that same string. This is very useful to storing instances for later retrieval, like inside files, databases, in memory stores (like redis or memcached), or just anything that accepts text. For example, saving a User class instance with its properties into a Session, so after this is retrieved in the next request we can restore the same User instance without having to pull it out from the Database. Hey, it just an example.

He mentioned how, in Australia, Facebook had been caught designing algorithms to identify stressed, overwhelmed, and anxious teenagers on its network, presumably to assist advertisers who might want to target them. Google has faced its own parade of scandals, which include the accusation that it illegally collects children’s personal information through YouTube, a subsidiary with algorithms that can push viewers toward increasingly polarizing and vile content—from neo-Nazis to Trump-bashing conspiracy theorists. Why? Because that’s likely to keep us most engaged, thus maximizing Google’s ad revenue.

We have not been given the lead in the cosmic drama. Perhaps someone else has, perhaps no one else has. In either case, we have good reason for humility.

A mote of dust. Suspended, on a sunbeam. Our planet is a lonely speck in the great enveloping cosmic dark in all obscurity and all the vastness there is. A pale blue dot.

Millennials love to complain about other millennials giving them a bad name. But as I fumed about this 27-year-old’s post office anxiety, I was deep in a cycle of a tendency, developed over the last five years, that I’ve come to call “errand paralysis.” I’d put something on my weekly to-do list, and it’d roll over, one week to the next, haunting me for months.

So next time you go to write a super clever line of code, think to yourself "Will the benefits of this super cleverness be outweighed by the future issues in maintaining and understanding the code?" And if there is any hesitation at all, then you better not be clever, because 3 months from now you will come across that code and say "What the hell was I thinking?" Then you’ll end up rewriting it anyway.

My head says, "Who cares?", But then my heart whispers, "You do, stupid..."

Hard work beats talent any day of the week!... Not really sure about that.

USB-C normally transfers data by the USB protocol, but it also supports Thunderbolt… sometimes. The 12-inch MacBook has a USB-C port, but it doesn’t support Thunderbolt at all. All other modern MacBook models support Thunderbolt over their USB-C ports… but if you have a 13-inch model, and it has a Touch Bar, then the right-side ports don’t have full Thunderbolt bandwidth.

The management by wandering around ( MBWA ), also management by walking around, refers to a style of business management which involves managers wandering around, in an unstructured manner, through the workplace(s), at random, to check with employees, equipment, or on the status of ongoing work.

“Multitasking is the opportunity to screw up more than one thing at a time.” ~ Anonymous

Hitler’s persuasive impact came from his ability to strategically express emotions—he would “tear open his heart”—and these emotions affected his followers to the point that they would “stop thinking critically and just emote.”

Even if you get what you want more than anything in the world, you will have to give something up. If you want to live an exceptional and extraordinary life, you have to give up many of the things that are part of a normal one.

Capitalism is why there are six empty houses in this country for every homeless person but thousands still freeze to death. Capitalism is why we waste 40 percent of our food while children die of starvation.

Most of us tumble into our lives. We become who we are almost by accident. Most are afraid to look backwards, afraid to find out that maybe we should've done something else.

Do Holograms Have the Right to Free Speech?.... The first amendment gets confusing when you can't shoot the messenger.

Don't fear the robots. They're doing menial work that no human should waste their life for. The real issue is where do we go from here? Answer: universal income. Free people to invent, explore, and appreciate life on the terms only the wealthy have previously been permitted. No fear of starvation and homelessness, no mind numbing widget-making job. Think big!

The most awesome thing about the eye is the real time post processing made by the brain, which transforms an otherwise dull, mostly blurred and monochromatic image in a vivid, complete and vectorized image, so that is crisp even if a part is corrupted by glass lenses, uneven lighting, or movement.
