I would recommend... statistics.

If you already know Python, learning how to do the same things in a different environment doesn't really add a skill to your resume. It probably means you can apply for more jobs/work on different projects but for each job/project you would be the same candidate as before. Almost like branching out your skill tree rather than extending it.

On the other hand, at a time when importing a library and throwing it on a dataset (without understanding what it actually does) is becoming easier, having a comprehensive understanding of probability, statistics, calculus and linear algebra would be a huge differentiator.

As far as languages go, Scala comes up a lot in data science job postings where I live, but my experience is limited only to trying out the Scala API of Spark. Maybe someone with more experience can shed some light on this.
If I remember correctly at a Vault Conference few years ago Dave Chinner say that xFS codebase while actively maintained should be considered legacy since it's not really possible evolve it anymore and the better way to go is a complete re-design so a new filesystem, a thing that will not happen in xFS upstream... I do not find any transcript now, but looking for it somewhere in the web surely exists :-)

So yes, it's rock solid and battle tested, certainly a safe choice respect of btrfs (buggy and not really good in production despite many do not care) or bcachefs (solid, stable, but essentially feature-less in today's implementation) but nothing more... RH and Oracle seems to push it a bit inconstantly but I still have to see any real plan...

Hey Franky47 i saw the lightsaber that you made, i like it very much, i learn a lot from your story, thanks for sharing.

For me i think the greatest accomplishment in 2018 is that i took my diploma in computer things, now i'm working on a project using Laravel && Vue as freelance project i'm working on it all days, i learn a lot of thing every day, sometimes i get depressed but it's normal i get up one more time and try to keep working.

That outlook is a product of the way you look at the data, not the data itself.

How are laptops not reproducing? If you looked at the population of laptops in the world when they were first introduced - and then tracked them through the years, they have clearly started reproducing. They even evolved! The basic shape stays the same, but they are clear evolutionary trends, like the taxonomy, outwinning the poor designs, branches of evolutionary traits etc!

Of course you can choose to look at the people that are building them, but how do you actually know that laptops are not "parasites" for example? Or a symbiotic life form like dogs? Yes, individual humans might take specific actions for building specific laptops, but so what, we take actions to raise and walk dogs also. Do we as humans really have a choice of stopping producing laptops? If not, couldn't it be just as easily seen that laptops actually use us to reproduce? Like flowers use bees to reproduce? You don't see flowers as being less alive because bees are ultimately required for them to reproduce?

Sure, one might need to talk more about the design of a laptop, the basic idea of a computer in a portable interface with certain features - not any individual physical laptop as being alive. But why not? People are surely not only alive in a physical sense. Many of the physical differences and transformations actually don't make much difference. It's the inherent internal something (entity? information? idea? soul?) that is more alive than the physical body itself.

The point is, "property of self replicators in their competition for life and reproduction" - is not a very good metric for consciousness. Many people don't see it as coming from the data itself, and more being a predetermined paradigm or outlook on the world, which someone already comes in with, when they look at the data. When someone with another outlook (for example that consciousness actually uses the physical world, including the reproduction cycle) to its own goals, not the other way around - then the data starts supportnig that too. It's all about how to look at it.

Will there be a colour change for Chinese New Year(春节）, Eid, Diwali, Yom Kippur? Just seems on that a side should be taken. And even if it isn't about religion, why theme it around Santa? Are there not more globally relevant moments or people to highlight?

There's no explanation required. Given the context of the quote, that person was simply being condescending and dismissive.

Effectively, it means "I deem what you do and how you do it to be lacking in worth, therefore you must be a waste of space in the same manner as the worst of the Golgafrincham race".
Why do you assume that every aspect of the world can be understood as "testable science"? What basis do you have for that belief?

In the same sense one could say that people on your side of the argument are simply "uncomfortable" with the notion that not everything can be understood logically and predicted, including big important things in their own life, but also the larger truths of the universe. And so instead of looking at the other experiences and data, which don't fit into an understandable paradigm - they tend to ignore or deny them.

This is a really nice article. "usually ..... A is 440hz". The 'usually' here is an interesting topic by itself: https://en.wikipedia.org/wiki/Concert_pitch

Anyway, I do have some questions:

- regarding the universalness of this. Is it (the transposing of instruments) like this everywhere or is it different in some parts of the world? (some things differ wildly, like the whole 'fixed-do' versus 'movable-do' thing.

- If I look at a score written for an alto sax, How can I tell which note is meant ?

- In jazz, people learn a standard in a certain key, and when that tune is called, it's called together with a key, usually to adapt to some constraint (like the singer's vocal range). The musicians mostly can adapt on-the-fly. Is there something similar in classical music ? (an example would be to transpose Beethoven's 9th from Dm to Em)
It does run a full Python 2 and 3 IDE called Pythonista, including support for making graphical applications, debugging, and even running a limited shell called StaSH with a bunch of PyPy versions of a typical POSIX userland.

There are other IDEs for other languages, too, although Pythonista is the star at the moment.

So it's not as though programming, even graphical using UIKit, isn't possible just because there's no Xcode.

Christmas?! Everyone knows that the red title bar is a memorial to the former Soviet Union:

"On the previous day, 25 December, Soviet President Mikhail Gorbachev, the eighth and final leader of the USSR, resigned, declared his office extinct and handed over its powers—including control of the Soviet nuclear missile launching codes—to Russian President Boris Yeltsin. That evening at 7:32 p.m., the Soviet flag was lowered from the Kremlin for the last time and replaced with the pre-revolutionary Russian flag."

Patreon has been on a spree to ban people that think the wrong way.

Matt Christiansen had a call [1] with Patreon to discuss their banning of Sargon of Akkad. Sargon was notified of the banning by his patrons, not Patreon, and had no recourse to challenge the decision. In the call Patreon made it clear that their platform is;

1) explicitly anti free-speech

2) is not a free market (they can ban you for arbitrary reasons, for things posted anywhere including leaked private messages)

3) their rules are enforced in a subjective manner by design

Considering that they have banned many people that disagree with progressive PC ideology, which seems to be a moving target of increasing religious [2] fervor, I can't see why anyone would trust their platform at this point and rely on it to build their income.

Even progressives might like the so-called TERFs fall on the wrong side of the party-line at some point, so I can't see how anyone can trust their platform as a source of income. Unless you of cause love staking your income on the arbitrary whims of the ideologues at Patreon.

Don't forget that schools and school districts get special educational and volume pricing, so they're not paying the same prices for iPads and apps as consumers. I believe schools and school districts that allow parents/caregivers to rent-to-own iPads may do so at these reduced prices, passing the savings on to parents.

I think a cheap, plastic iPad would be a significant downgrade. You can't broke a hole in the back side of an iPad, and no plastic screen can match the strengthened glass — not only does impact cause it to crack rather than shatter, but I don't think Apple would or even could put their Apple Pencil-compatible touch technology on to plastic.

What do you mean with "not physical"?
Thank you for that concise but clear explanation of what I always felt was lacking with many over-scientified views of profound subjects like consciousness.

We don't push back those models because they are "uncomfortable", make us feel bad, or inferior, or anything like that - but because they are simply non-functional! There are many aspects and phenomena in the world, in human interactions, in my own consciousness - which are simply not explained by the reductionist view! "Based on some complicated network of neurons" is not good enough! I clearly have these phenomena and experience, and this "complicated network" explanation just gives no explanation at all really! While other less scientific models do.

I'm like "sure, I can accept whatever science you can give me and become a fully logical being, but don't ask me to ignore obvious phenomena that I know I have and experience, that is just stupid!".

Your understanding of the reductionist view may be incomplete; it is very functional and there’s no need to ignore phenomena.

Less scientific models can be simpler and functional, but that doesn't mean that they’re more correct.

The concept that artist should come up with new ideas and create something new is narrow. Seeking perfection in somee restricted style and going deeper instead of different is also creativity.

The way I see Bach is that he mastered, refined and perfected the style. People who came afterwards had no choice but do something different. Others are climbing different peaks because Bach stands at the top of Mt. Baroque.

Mozart and Beethoven are geniuses. They started something that has been never perfected. Bach's music does not feel like a work of genius, it feels goodlike and nonhuman.

The best MOOC course I have taken this year is the one I'm currently doing. It is called nand2tetris [1] where you actually build a 16 bit computer all the way from nand gate. Along the journey you will be building the memory, operating system and also writing a compiler. You can follow my journey in tweets [2].

Another great course I'd recommend is Big History[3]. Like nand2tetris,it gives you a great overview of the entire history of our being. From Big Bang to 2018.

Also, I am looking for some great online courses on Distributed systems. It would be good if assignments are challenging and where you have to write a lot of code.

> drag at sea level is a killer.

Yes. Apparently when jet turbines came along they were discounted as ever being useful for commercial/passenger airplanes because they were so incredibly inefficient. I mean, really incredibly inefficient.

What they didn't take into account is that the turbines allow you to fly at much, much higher altitudes. The reduced drag there more than makes up for the lower efficiency. And gets you a smoother ride and higher speeds as well.

Modern turbofan engines are much more efficient, but that's basically because they really are turbo-props with enclosed propellers, though we call them "high bypass turbofans".

And of course if jets have to drop to a lower altitude, for example because their cabin has become depressurised, range is drastically reduced.

For the typematic delay, I have no clue why it is so slow on Linux by default. Probably somebody has set those values 30 years ago and then nobody cared to update them.
I use 'xset r rate 200 40' and when I use another Linux computer, typing feels just broken, super slow (Windows has better defaults than Linux in this regard). The weird part, there is no reason why keystrokes should have such a huge delay. Changing the xset values improves the user experience in a quite dramatic way.

The issue is that components dont build systems. Sure, maybe that get concrete that tests to 35Mpa. But was the embedded steel reinforcement coated properly, or will it rust? Were the balconies and doors sealed? Did anyone wash grout down the drains? And then imagine someone finds a problem, like “leaks” in a sibling comment. Do they revisit the strucutral issues that led to it? Or do they patch it up with a new 3rd party tradie and walk away?

The idea being that your point inspection are finite. And the responsibility will be laundered behind a legal or organizational structure. Youre not going to reach anyone “responsible” for systemic issues. And as soon as you do that youll dampen all relevant investment activity.

Using this kind of rational-choice-based theory assumes complete control of the way your brain processes information and the channels it chooses to focus on, which simply isn't accurate.

How Perfectionism Plays Out in Startups
Any other classic examples of perfectionism at play in a typical startup?
1. Universality of transposition: These conventions apply wherever people use western instruments.

2. Alto sax is always in the key of E flat. That means the note called A flat played by an alto sax would be C on the piano. Likewise tenor is always in the key of B flat. A huge advantage to this arrangement is that the fingering is the same no matter which instrument you are playing; that means it is up to the composer to transpose notes as appropriate. The saxophone family is amazingly cohesive and consistent because Adolphe Sax invented it in one fell swoop.

3. Well-trained classical musicians can transpose at will. I read a story by the composer/pianist Andre Previn whose touring orchestra was late to a concert hall due to the bus driver getting lost. He was playing the piano in a concerto. What he didn’t know was that the entire piano had detuned up half a step. It meant that The moment he sat down to play a concerto in C minor he was therefore playing in C sharp minor. The orchestra caught this immediately and everyone transposed up for the rest of the concert – on the fly.

Edit: I mysteriously screwed up keys of alto and tenor sax, both of which I play. Idiocy caught by klez and duly corrected.
