> At the end of the day, someone has to 'waste' money, in order for companies to earn money

I also used to feel this way, but I no longer think its accurate. This is most obvious in digital business-consumer goods today. Imagine I make a game. And it cost me about $100 to make this game. And you really want this game and would pay $5 just to get to play it. But I'm nice and sell it to you for $1. You certainly haven't wasted any money. And the fact I then sell it to 10,000 other people also doesn't mean you've wasted any money, nor they. Yet I've somehow made an immense amount of profit.

Even in the more difficult scenario of business to business material goods trades, it doesn't hold true. Imagine I sell iron and you need iron to make your widgets. It costs me $4 to produce a single unit of iron, but that's largely because I have an extensively refined and stream lined operation, and am able to benefit from an immense economy of scale. I sell it to you for $10. Well it seems that you must be wasting money, but the reality is that even if you bought the iron mine yourself and started producing your own iron you'd end up spending far more than $10 to create the volume of iron you need. So even though I'm again making immense profit, you're also not 'wasting' money in buying my iron.

This is why even huge companies are not entirely vertically integrated or producing their own supplies in other words. It's because buying from somebody else, even when that person is profiting immensely from the exchange, is not going to be inherently more expensive than if you did it yourself. And this is even true for simple no-skill goods like semi-raw materials. Get into skilled products, like semiconductors, and this all becomes even more true.
The original comment could then still hold, though. Yes, it might be like Slack/IRC/whatever, but better.

Yes, I have also had this experience and I hate how in the end, the code is very hard to read, while the for loop was probably trivial.
My refurb X220 came with Win10, and it would just sit there, burning 25-30% CPU for apparently no reason, doing something probably update related. The battery isn't exactly new, but it's a 6-cell with about 40Wh capacity remaining. That should be good for more than just 1 measly hour.

Apparently Win10 sometimes needs to sit like that for a couple of days after installing, for reasons.

So I ditched it and installed Linux Mint. And whattayaknow, it installed faster, it didn't need any additional drivers and it doesn't idle at 30%. Everything Just Works™.

A 2011-vintage laptop with an i3 (plus 8GB RAM and an SSD) is still a perfectly usable machine today, if you pick the right OS.

I'm still getting that 9-cell battery of course, because you can still get brand new ones.

I would suggest that the biggest group to mourn CRT technology would be our feline overlords. I had several cats that used to perch themselves atop a screen, trying to capture my attention and keeping warm but blocking an air vent in the process.

The switch to DVB-T from PAL saw us recycle our last CRT telly. I threw out my Trinitron computer monitor some years earlier. Its sharpness had deteriorated over time. Text became too fuzzy, perhaps something to do with electrons mentioned in the article.

I miss the vertical pixels - 1600x1200 was a standard but LCDs embraced 1080 panels from the Blu-ray craze. Luckily I have a 1024*1280 LCD (rotated) for A4 documents.

Color/styled text is a weird case, since it tends to be used for improving output (e.g. highlighting a “diff” or code syntax). It can be annoying to have all that helpful highlighting go away just because you added something like a pipe to “less” in your command to keep your text from scrolling away. The real problem is how a program is supposed to know when your pipe is meant to be interactive.

Technically terminals can play the interactive role in place of “less”: ^S/^Q, scrollback and search, etc. If that were more common, programs might not be misusing color/style sequences like this (as there wouldn’t be a common “interactive pipe” use case to support).

It's an experience thing. Color gets in the way in many cases. You need a way to turn it off. If you can't, then when you pipe it to a text file, it turns into garbage.

Worse, many programs break when you start getting fancy. If you would just stop trying to add color to your node programs, stop trying to add emojis, stop trying to control the entire terminal window, then suddenly everything would work much better. If you kick off multiple processes, you can simply console.log() instead of having to set up an RPC interface to communicate with the main process. (This actually happened.) If you stop putting emojis in your error messages, then WebStorm can highlight the stack traces automatically when you run in the debugger, enabling you to jump to the stack trace just by clicking on it. This breaks when you add emojis. (Also happened.) And if you stop adding color, then you can redirect to a file without screwing things up.

In short, stop getting fancy. :)
It clearly does.

I was under the impression that automated layout had gotten a lot better over the past few years. In particular, it's very different than hand layout and works best when you let it go whole hog at a chip, but doesn't really compare well to hand layout on tiny sections.

Don't know the details anymore, but the default experience on major Linuxen was to display plain files in blue color (eg. when listing files using the ls command). So that when you switched to an inverse (white-on-black) video setting from the default black-on-white, you had a hard time to read blue-on-black text for one of the most basic tasks on the command line without resorting to customize terminal colors. Don't know who came up with such a usability fail.
It was possible to do face swap images in photoshop for a long time and people learned not to trust random nude celebrity images, I believe it's the same thing now with video.

There are some fun grey areas where you have someone doing porn who actually looks like a celebrity.

The good news is that you should be able to easily detect a face swap video, by comparing the face against public images that were taken of the celebrity and comparing the rest of the video with porn videos (like Youtube's ContentID).
While that may be true, my point is that it is almost certainly possible to make your code go faster than it is already, and also become more readable in the process.

And so saying that python is either slow or ugly and unreadable is perhaps an unfair characterization. I may be wrong here. I haven't benchmarked the code in question, but I think that even for the algorithm you're trying to do, with the special casing, that function could be significantly simplified.

Edit: I'd be curious to see example data that is passed into this function.
Um, I just wrote a lengthy comment about how this is not exactly the case: https://news.ycombinator.com/item?id=16322795

It's only mentioned in the comment, but the amount of mistakes in tech-related writing, by native English speakers and otherwise, is gargantuan and overwhelming, and I'd wish using something like Grammarly (if safe, open source and so on) was a requirement for putting your writing on the web.

As it is, the quality of writing is so bad, that I (as a foreign speaker) don't improve my English in any way by reading it, and I have to be very careful not to repeat these mistakes in my own writing later.

The fabrication process itself might be the hardest part.

Everything is stitched manually with comfortable size tolerances.

Actually, this might be a false problem .. I don't know how precise the measures need to be in order to fit.

So we might not have to automatize fabrication; just to change how sewing patterns are applied.

I’d like to thank the author for sharing a very practical view of problem solving in the data science space.

Can I suggest julia? Its very easy to understand coming from python, and performant code can be had usually in easy to read implementation of the expressions in whatever paper you are basing your work upon.
That's their job.
I have an impression that there are features in Python that give very little programmer productivity but make the language slow. It should be possible to implement a hypothetical FastPython without such features but with great performance gains. Of course it wouldn't be compatible with most of the libraries. I can imagine though that porting most of the libraries to FastPython still would be a manageable task. I wonder if such projects had been attempted.

Well not actual privacy scandals, but shocking practices that some of the community took so. The most recent was an easter-egg extension covertly installed in about everybody's browsers, and there was a partnering I read of with a German web company.

> Homoiconicity ... same representation internally and externally

That's why it makes little sense. Lisp does not use the same representation internally and externally. Externally programs may be characters in a file or on a display. They are interned by reading them into data structures. Running programs may use different representations and one popular is the internalized representation - which is used by Lisp interpreters.

> SBCL compiles everything to machine code...

If you use its compiler. If you use its interpreter, it doesn't.

http://sbcl.org/manual/index.html#Interpreter

Sure, using an interpreter is observable. That's the reason why they exist. They offer different services to the user. Many Lisp systems offer hooks into the interpreter, which let you watch it working.

> s-expressions are tree representing syntax...

Actually s-expressions are a data format, not a format of the programming language Lisp. S-expressions know very little about Lisp - basically it provides an elaborate/hierachical form of a tokenizer output. The reader parses numbers into number objects, symbols into symbol objects, etc.

But the reader does not know anything about the syntax of Lisp, which is defined on top of s-expressions. Thus the s-expression does for example NOT represent any syntactic informations about the source code: after READ it is not known what a symbol actually stands for. Is it a data object, a function, a special operator, a macro, a variable, a local function, a local variable, a package name, a goto tag, ...? The s-expressions does not tell us. We also don't know what are function calls and what not. Etc.

From an AST I would expect that it represents syntactic information of the programming language Lisp.

To contruct this one needs to traverse the s-expressions: using compilers, interpreters and/or code walker (tools which can traverse code, collect information, maybe transform it).

The ANSI CL spec even lacks a way to access the syntactic information in macros. The facility for that didn't make it into the standard, though implementations provide a quasi-standard way.

My progress was pretty quick due to forced immersion. Essentially:

Year #1
- Self-study with books/audio courses. Got me up to reading simple newspaper articles, struggling with TV news.

Year #2
- Started with a week-long residential Dutch course. It felt like I didn't learn much new grammar or vocab, but suddenly I was thinking in Dutch, no longer mentally translating. Very expensive but definitely worth it.
- Then my company (management consultants) decided I was ready to work full time in Dutch with Dutch clients. The first month was very tiring: I felt 20% IQ points dumber, and could either listen or speak in meetings, not fast enough to do both at once :)

Year 3
- After that, I was ok working in Dutch and speaking it socially.

Year 4
- By the time I left the Netherlands, I was managing a team of 25 Dutch people, doing meetings, performance reviews in Dutch.

I subsequently ended up marrying a Dutch guy. While we left the Netherlands 7 years ago and now live in London, at home we speak probably 30% Dutch/70% English.

Dutch was never a language I expected to learn. But I am very glad I did. The sounds of the language still make me smile :)

I don't know many fellow Americans that are of Norwegian descent but the US fairs better than the UK on lists of human development, happiness, and productivity. That has to mean something.
That may be the case. However, my point is that we started with a rather direct implementation of a formula in a paper. This was very easy to write but took hours on a test set (which we could extrapolate to taking weeks on real data!).

Then, I spent a few hours and ended up with that ugly code that now takes a few seconds (and is dominated by the whole analysis taking several minutes, so it would not be worth it even if you could potentially make this function take zero time).

Maybe with a few more hours, I could get both readability and speed, but that is not worth it (at this moment, at least).

The comment about the benchmark data being large is exactly my point: as datasets are growing faster than CPU speed, low-level performance matters more than it did a few years ago (at least if you are working, as I am, with these large data).

Use 'less -r' to display ANSI color in less.
Nothing too mysterious in the examples in the SEC Alert link. One just has to keep in mind that these ETFs leverage the daily return and then take into account the compounding effects. If you have an index with normally distributed returns with mean m and volatility v, then the long term compound return c is

c = m – 0.5 v^2 .

An ETF which leverages k times will have returns with mean km and volatility kv. The ETFs long term compound return e will be

e = (km) – 0.5 (kv)^2 = k m – k^2 0.5 v^2 = k (m – 0.5 v^2) – (k^2 – k) 0.5 v^2 = k c – k (k – 1) 0.5 v^2.

For k > 1, the second term will always be negative so the ETFs return will always be less than the leveraged compound return of the underlying index.

Whether the leveraged ETF return will be more or less than the underlying index return depends on whether

c > (k – 1) 0.5 v^2 <=> m – 0.5 v^2 > (k – 1) 0.5 v^2 <=> m > k 0.5 v^2 <=> m / (0.5 v^2) > k.

In other words, the leverage k has to be kept less than the m / (0.5 v^2) which is the well known Kelly Criterion.

You could also pipe the output through a program that filters ANSI colour codes. That'd be an extremely simple utility and fix for the problem.
This doesn't make sense. There's no point in disabling color, and even if we need we can just pass the de-facto standard option. The homebrew guy did the right thing, and putting it on the list like "hall of shame" is definitely is not a good idea.
> Sounds painful.

I'm sorry but this is denial. There's an even better solution - quit Twitter and you'll never have to face the fact that Nazis exist.

Or, come to the realistic conclusion that Nazis exist, like global warming and terrorists, and denial won't make them disappear. FWIW Twitter and the gang have drastically increased their anti harassment detection and enforcement, which is a step in the right direction. You're setting the wrong example for the new generation - solution to countering hate isn't a nanny state or fleeing to make believe denial lands.
