kmmlng··on Basic Music Theory
While it can be a good idea to supplement with material like the links you provided, at the end of the day you have to understand and internalize the canonical approach to music 'theory'. Why? Because the main point of it all is that you can communicate with other musicians and it doesn't do you any good if you create your own secret language that no one else understands.
kmmlng··on Let’s avoid talk of ‘chemical imbalance’: it’s people in distress
I think there is an argument to be made here that prescribing medication might be treating the symptoms but not the root causes, which will lead the patient to ignore the root causes, leading to worse outcomes in the long run while an improvement can be observed in the short term.
kmmlng··on Ask HN: Name one idea that changed your life
SA for your own life sounds intriguing. Do you have a concrete example that elucidates how this could be implemented? The concept still seems a little slippery to me.
kmmlng··on Extremely disillusioned with technology. Please help
How has turning to God changed your life? Did it change what you do or how you view the things you do? In other words, would your life look the same to an outside observer but there has been an internal shift in your mind?
kmmlng··on New iPhone SE
In my experience with a fairly recent and expensive set of bluetooth headphones (Sennheiser Momentum 3), it works well most of the time, but in 5% of cases it does not. If you use your headphones a lot, those 5% get annoying very quickly.

Some issues I've noticed:

- My tv (flagship LG OLED) always has trouble connecting to the headphones. I usually have to turn them off and then back on again at least once. Macbook and iPhone rarely have trouble connecting. Connecting on Windows has always worked so far.

- When I'm connected to both my Windows laptop and my phone, in a skype conference on the laptop and get a call on my phone, the skype conference is automatically terminated. FOR ALL PARTICIPANTS. That's insane.

- To make the previous point even worse: except for the ringtone, the audio from incoming calls never even goes to the bluetooth headphones. The audio from outgoing calls does, however. This is all on an iPhone SE.

- Sometimes when I listen to music, or watch a video on a Windows machine, my bluetooth headphones will just pause the playback every couple of seconds. This only happens on Windows.

- If your headphones are connected to multiple devices, you have absolutely zero control over what is happening. You might be listening to music on your phone, but some notification from your computer will interrupt your playback even though the computer is set to silent.

I could go on and on and I've only been using bluetooth headphones for a month. There is a LOT of polish missing here. That being said, this could be a great technology and it's not too far off at the moment. There certainly are some advantages over wired headphones as well.

kmmlng··on Using Anki to remember what you read
My hunch is that Anki is mostly useful for stopping you from forgetting things you have already learned. The actual learning is better done outside of Anki.
kmmlng··on Germany is moving beyond nuclear power, but at what cost?
Note that Jülich was not exactly a typical nuclear power plant: it was a prototype pebble bed reactor linked to a research facility.
kmmlng··on Magnesium and major depression (2011)
I once tried supplementing magnesium while in the midst of moderate depression. Interestingly enough, the effect was not relief, but rather major, absolutely crushing depression (i.e. cannot get out of bed all day depression). I went back to moderate depression after stopping the supplementation and a subsequent second attempt brought back the major depression. By that point I gave up on the whole thing.

Anyone have a similar experience or maybe some insight that might explain this?

kmmlng··on We're Entering a Golden Age of Podcasts
I live in Germany. I can only see German-language podcasts in the app. If I want to see podcasts in English, I need to switch my whole iTunes account to a different country. Of course, that creates problems elsewhere.

I mean, come on. Most of the interesting content is in English. This is a simple feature.

kmmlng··on Elon Musk’s Ultimatum to Tesla: Fight the S.E.C., or I Quit
I think part of the answer might be that Germans invest much less than most other nationalities. They do save, but in times of practically non-existent interest rates, that does not get you very far.
kmmlng··on App-Only Banks Rise in Europe and Aim at Traditional Lenders
Not French, but German here. TANs are obviously used for transactions, but I've never seen them used for login purposes. To add insult to injury, the _only_ permissible password length for my bank was 5 (five!) characters.

Looking to make a switch right now..

kmmlng··on Decline of Global Extreme Poverty Continues but Has Slowed
I think the point is: the problem might be more deep-seated than capitalism. If it were not possible to find this problem in any other societal system, then you could make a convincing argument that it might be exclusive to capitalism. But this is not the case. Other systems have been tried. Regardless of how you feel about these alternative systems, they were considerably different from capitalism and the problem occured there as well.
kmmlng··on Big fish are found deep not because of age, climate, or prey, but because of us
It seems that all these points assume naturally unlimited and indefinite population growth, but it is projected that the world population will reach a certain point and then level off (see https://ourworldindata.org/world-population-growth for some charts).

The basic argument is that increasing the education of women leads to fewer children. You can already see this in developed countries which are actually starting to exhibit negative population growth (e.g. Japan).

kmmlng··on Is going vegan actually helping battle climate change?
While I agree with you about the complexity of the issue, it doesn't seem fair to compare local meat to imported plants. What about local meat vs local plants? Local plants vs imported meat? Imported meat vs imported plants? By cherry-picking a single one of these combinations, you can make either side look favorable.
kmmlng··on Scientists plan huge European AI hub to compete with US
There is a difference between east and west Germany, but not specifically between the Länder.

In 2009 you would have gotten (before deductions) ~34873 in the east and ~37852 in the west. In 2018 it is ~45863 in the east and ~45900 in the west. This is all assuming a full-time E13 position.

kmmlng··on Trial of a blood test that detects eight common forms of cancer
Your sensitivity intuition is a fantastic way to remember it. I had to look it up myself, but hopefully this will finally make it stick :)
kmmlng··on Trial of a blood test that detects eight common forms of cancer
You labelled both TPR and TNR as "specificity". True positive rate should be sensitivity.
kmmlng··on Let Me Ruin This for You: The Schadenfreude of Criticism
Without having more details, I generally wouldn't say one would feel Schadenfreude in your example.

Now, if your acquaintance is obnoxious or is putting everyone down for not being able to afford their dream vacations, then yes, Schadenfreude would apply.

In more general terms, you don't feel Schadenfreude whenever something bad happens to someone. There has to be a sense of "Well, that guy had it coming".

kmmlng··on A Map Showing How Much Time It Takes English-Speakers to Learn Foreign Languages
You'll also have a hard time really internalizing vocabulary. If you're learning Dutch and you already speak English and German, you can quickly get to a level where you are able to read Dutch texts. This is because half of all Dutch words have very similar German or English counterparts. But since you just understand them effortlessly, your brain doesn't actually learn them. You'll find yourself trying to say something in a conversation and the words just won't come to you, even though you would have no problem understanding them in written text.

If that happens you can always flip a coin and just either dutchify the English or the German translation of what you want to say, but it's not the most elegant solution.

kmmlng··on How do you move out of a smarthome?
Not just to Americans. I'm an expat in the Netherlands and interact with lots of people who came here from various different countries. It's bizarre to everyone.

Seems like there are two options. (1) You can do it the Dutch way, i.e. every time someone moves they'll have to take their floors out. Those floors often won't fit into your new apartment, so you're just creating lots of waste. Not to mention all the effort associated with it. You will have to remove the floors, but also the person moving into your place will have had to remove the floors from their old place. (2) You leave the floors in when you move out. Then the new tenant/owner can decide whether to keep them or not. In the worst case, both new and old inhabitant will still decide to remove the floors. In the best case, no one will have to do anything and no waste is created.

So what could possibly be gained from the first way of doing things? Genuinely curious if someone knows the reasoning behind this.

kmmlng··on An Intuitive Explanation of Convolutional Neural Networks (2016)
I would argue that in a signal (1D) you can expect some sort of relationship between consecutive elements. In an image (in essence a 2D signal), you can expect a relationship between consecutive elements not just on the horizontal, but also on the vertical axis.

If you arbitrarily represent a signal as a 2D matrix, then abrupt changes in the gradient on the vertical axis are meaningless. But the same is not true in an image, which is naturally represented as a 2D matrix. Here, a sudden change on the vertical axis usually corresponds to an edge in the image.

If you represent an image as a 1D array, you throw away spatial information. So I'm not sure about the 1D-ness just being in ones head.

kmmlng··on The correlation between IQ and income
Definitely, but the author is still right to point out that black people are overrepresented in the sample. You could argue that there is still a gap between black and white Americans in terms of education, wealth, etc., and IQ is partially influenced by environmental factors such as maternal/paternal education level (http://www.sciencedirect.com/science/article/pii/S0899900707...).
kmmlng··on Ask HN: What do you use Machine Learning for?
I imagine only training on genuine visitors would be tricky with any traditional classification approach. Even having a 90/10% split of positive/negative training data is difficult since a lot of classifiers will just degrade to a majority vote.

Maybe a Restricted Boltzmann Machine or something similar?
