Deconstructing the CAP theorem

In computing, the so-called CAP theorem (1999-2002) has become both an icon and a bone of contention in the world of databases — a supposed truth about distributed systems. A lot has been written about it since it was formulated, especially around the recent debates on `SQL/noSQL’, but its many hearsay formulations are beset with a number of problems.

If you work with databases, reading this might be wise.

A person should be strong

This entry is part 11 of 72 in the series My Journey

It suggests that a person should aim to be strong, but not just in a physical sense. They should aim to be resilient, free thinking, confident and yet remain humble. They should learn to be self-sufficient and useful to their loved ones and they should be aiming to always progress in some way.

~ Chris Rowat, from «http://www.parkourgenerations.com/node/9399»

Written to have 5 parts, plus the introduction, he’s only completed two parts so far. But if parkour/art d’déplacement/free running you love, read this you must.

What if there is no spending problem?

Summing up: Liberals and conservatives agree that we have a long-term problem, but they argue about what kind of problem: a government spending problem or a healthcare cost problem.

Recently I ran into a potentially game-changing question: What if there is no problem? In other words, instead of being trapped in the dismal liberal/conservative argument about which apocalypse we’re headed towards, what if we’re actually not headed towards an apocalypse at all?

Abandon all hope

Less well known is Prometheus’ second gift. In Aeschylus’ “Prometheus Bound,” the chained Titan is pitilessly interrogated by the chorus. They ask him whether he gave human beings anything else. Yes, he says, “I stopped mortals from foreseeing doom.” How did you do that, they ask? His response is revealing: “I sowed in them blind hopes.”

The distress of the privileged

If you are one of the newly-visible others, this all sounds whiny compared to the problems you face every day. It’s tempting to blast through such privileged resistance with anger and insult.

Tempting, but also, I think, a mistake. The privileged are still privileged enough to foment a counter-revolution, if their frustrated sense of entitlement hardens.

So I think it’s worthwhile to spend a minute or two looking at the world from George Parker’s point of view: He’s a good 1950s TV father. He never set out to be the bad guy. He never meant to stifle his wife’s humanity or enforce a dull conformity on his kids. Nobody ever asked him whether the world should be black-and-white; it just was.

What’s lost as handwriting fades

Cursive or not, the benefits of writing by hand extend beyond childhood. For adults, typing may be a fast and efficient alternative to longhand, but that very efficiency may diminish our ability to process new information. Not only do we learn letters better when we commit them to memory through writing, memory and learning ability in general may benefit.

The real American discipline problem

I agree that America faces a major discipline problem, but I see the lack of discipline at the top: the bankers, the billionaires, the CEOs. Like Mike Rice, they’re out of control and need to face the consequences of their actions.

The Rice video was seen by Rutgers officials months ago, and their response was a wrist-slap: Rice was suspended for three games and told not to do it again. Isn’t that typical of how things go in America?

How to be polite

The practice of politeness is a collection of habits of mind and expression you do on a daily basis. You learn to say “thank you” because you are honestly grateful and “I’m sorry” because you honestly don’t want to contribute to the pain of the world. You learn to say “it’s ok” because you’re honestly forgiving and letting go of small things other people do wrong. This practice makes the rate of unproductive and acrimonious conversations go down, and the enemies you make are usually only the unavoidably unpleasant.

What if secretaries became programmers

But why do women make less? Is it for reasons we can all live with, or is the pay gap an injustice that needs fixing? Several reasons are frequently offered, together with explanations why we can live with those reasons. (Never forget that those are two separate conversations. Even if the whole pay gap could be boiled down to something as simple as “Girls don’t like math”, we’d still need to discuss whether that’s a problem we can or should fix.)

Debt: This time is different

Many seem to believe that if we worked our way out of debt problems in the past, we can do the same thing again. The same assets may have new owners, but everything will work together in the long run. Businesses will continue operating, and people will continue to have jobs. We may have to adjust monetary policy, or perhaps regulation of financial institutions, but that is about all.

I think this is where the story goes wrong. The situation we have now is very different, and far worse, than what happened in the past.

It remembers for keeps

Anyone who works with computers learns to fear their capacity to forget. Like so many things with computers, memory is strictly binary. There is either perfect recall or total oblivion, with nothing in between. It doesn’t matter how important or trivial the information is. The computer can forget anything in an instant. If it remembers, it remembers for keeps.

True friendship

True friendship develops not as a result of money or power, but on the basis of genuine human affection.

This tweet appeared the day I returned from training at the Académie Québécoise d’Art du Déplacement. Clearly I’m becoming a softie in my middling years, but I felt a real connection to the many people I had the privilege of training with. They were strong, humble, joyful, welcoming, and so much more.

Student debt

Put it all together, and even a student who works part-time and attends a second-rate state university can easily graduate owing over $100,000.

Welcome to the professional class, kid. Just don’t expect to keep any of the money you make. And I almost forgot to mention: We’ve let public transportation go to hell, so you’ll need to buy a car. (Here’s another loan.) We’re letting public schools fail, so if you have kids and want them to stay in the professional class, you’ll need to send them to private schools (Here’s another loan.) And we’re going to toss that national-health-care idea out on its ear, but don’t worry, if you get sick you can put it on your Visa.

What’s the constant?

This entry is part 10 of 72 in the series My Journey

This change really seperates people. It’s not going to be like it used to be. You can’t ‘go back to training’ as you once did. That one Jam that you remember is a small part of your whole experience that you remember fondly. It’s one highlight in a long journey, which isn’t just highlights. What’s the constant in these memories?

It’s Parkour.

You don’t have a job, you have a hobby

That’s the only test that counts. It’s not how hard you work, it’s what happens if you stop. If quitting means real hardship for you or your family, you have a job. If you keep at it even though you could spend the rest of your life skipping rocks at your house by the lake, you have a hobby.

I’ve got nothing against hobbies. The Weekly Sift is a hobby. One way to describe the Marxist vision of Utopia is that we’d all be hobbyists, and the world’s work would get done by people who just wanted the satisfaction of doing it. (That vision even works sometimes: Wikipedia, open source software, and so on.)

Overcoming instant gratification

The second way of living is the opposite: eat simple food in moderation, enjoy the Internet but with limits so that we can focus on important work, get away from TV and computers once in awhile to enjoy nature and being active and exercising, shopping less and having less possessions, finding focus and being mindful. It’s not that we don’t indulge in the treats of the first way, but we do it with a little restraint, and consciousness.

The republic of babel

But democracies need to be able to talk. I have to know more than just what you want to do or want me to do. I need to understand why you want what you want, and I need to be able to explain why I want something different. We have to be able to discuss the nuances of our hopes and fears and plans — what’s absolutely essential and what isn’t — so that we can cobble together a solution that we can all live with.
