knbknb··on Finland's prime minister wants her country on a four-day workweek
It's a vision, not a plan.
knbknb··on Ask HN: A New Decade. Any Predictions?
Off the top of my head, starting from some course notes on "Digital Transformation" :

Big Data - "I wish I had more data literacy" will be considered desirable by more people of the educated population. Although many people would like to have more (coding and data analysis) skills, often it will be wishful thinking like "Next year I'll be losing weight and get fitter".

Shift to the Cloud - This will continue slowly but steadily through the next 10 years. For IT pros, some classic sysadmin skills - such as patching cables, administering RAID devices, physically ordering PC components and configuring PC operating systems- will become obsolete (because it gets also more complicated. I'm looking at you Windows 10). These skills need to replaced with a "cloud literacy skillset". The tech giants will be pushing their cloud based offerings (because it's all pay-per use or subscription based)

Internet of Things - This will slowly also but steadily continue, as more wireless devices are released into the public space (LoRaWAN). Consequently IPv6 will become more mainstream. Many IoT devices will have many capabilities and see forms of integration, just like smartphones are powerful multitools today.

Innovative Manufacturing - 5G local grids, 3D printing and biotech innovations (tissue growth?) will become more mainstream in all parts of the globe where there is still a middle class.

Cyber Security - In most respects it will get worse, because nobody is able to understand modern processors and microcontrollers anymore. Even the smallest devices will have powerful CPUs in them because it's cheaper than secure special-purpose SoCs. Protecting Your real online identity will be super-important.

Artificial Intelligence - Spectacular applications and discoveries will continue to make national news, as will creepy misuse cases such as instant Face Recognition and deep-fakes.

Blockchain technologies - will become mainstream, as a mechanism to ensure authenticity of digital assets of any kind (e.g. "Live footage" videos). Many people will use it but few will understand it. Cryptocurrencies will find more widespread acceptance, as some central banks adopt them, tech giants promote them, and they can also be used for private banking.

Public health crisis - it continues as society ages. The opioid crisis, obesity and diabetes epidemics, and antibiotics resistance increasingly take their toll. Might also happen during the 2030s. The healthcare market will become more important and see some bizarre developments.

Long term global environmental problems - they will lead to economic collapse in many parts of the globe and to continental-scale dystopia (in Africa, Near/Middle East, Australia).

The 2020s will be completely unlike the 2010-2020 years.

knbknb··on Ask HN: A New Decade. Any Predictions?
I also think that Amazon will get Robotic Picking and Refilling in their Warehouses to work. Of course this will result in an large number of heartless firings of workers.

I doubt their cashierless brick-and-mortar stores will take off. (In 2019 they had such a pilot in Seattle I think).

knbknb··on L.A. is the perpetual dark heart of crime writing
Didn't know this name. I just learned that he was a co-writer for the TV series "The Deuce". Very interesting
knbknb··on Elon Musk tweets using SpaceX’s Starlink satellite internet
Will Starlink, when operational, put price pressure on satellite phone and internet service providers such as Inmarsat?

Or will prices for internet coverage in remote areas just as expensive as before?

knbknb··on Fertility Fraud: Artificial insemination doctors who used their own sperm
If the adult child finds out what happened, and the insemination doctor is still alive, is the child then entitled to a part of the doctor's (future) heritage?

Or if the child finds out when it is still small, or a teenager, will the child be entitled for child support payments from the doctor?

knbknb··on How I Became a Machine Learning Practitioner
How often do you go "back to basics" (read introductory book chapters, or classic papers, etc)?
knbknb··on Data Science Past and Future
This is a great insightful talk; starts with interesting historical perspective. Great video, great slidedeck. Why no comments?
knbknb··on Teach Yourself Programming in Ten Years (1998)
What's his name? I'd like to hear his songs.
knbknb··on What Stress Does to the Brain
The Great Courses has a non-free 24 * 30 min Coure "Stress and the Brain" given by Sapolsky .
knbknb··on Ask HN: When does it make sense to roll your own X?
Polyfilling is also some kind of "roll-your-own X".

https://en.wikipedia.org/wiki/Polyfill_(programming)

In web programming, it might sometimes be useful to write your own polyfill when you need to add a single feature for backward-compatibility reasons. Well, a third-party polyfill library that provides that missing feature perfectly might be available. However, the library is too big (with respect to file size) or adds too much complexity during the build process (by pulling in lots of other dependencies).

knbknb··on Brain imaging study reveals signs of Parkinson’s decades before symptoms appear
In humans (this time, not in mice )
knbknb··on Google's PageRank patent has expired
Maybe Stanford University no longer gets any license fees from Google for this patent. not sure
knbknb··on Ask HN: Is the “The Art of Computer Programming” Worth the Investment?
I recommend to read or even do the mathematical preliminaries, or whatever it is called. The first section(s) of Volume 1 represent 40 pages of very carefully compiled math fundamentals.

I'll read it again when I have the time. The other stuff is admittedly too difficult for me.

knbknb··on A book to learn R and Python in parallel for Data Science
I thought the Python equivalent to Shiny is Bokeh, see https://bokeh.pydata.org/en/latest/docs/gallery.html#gallery) ?
knbknb··on Why Wolfram Tech Isn’t Open Source
I remember this book + I own it. It is a very good book but way over my head. (Additionally, it serves well as a doorstop).

Still I admire the amount of diligence and energy that went into this. Wolfram spent several years _obsessed_ with this stuff. See his 2012 blogpost about his "quantified self" recordings: https://blog.stephenwolfram.com/2012/03/the-personal-analyti...

Maybe A New Kind of Science will create a surge sometime (just like Neural Networks were declared dead for several years, then Deep Learning came along and they took off)

knbknb··on GNU Octave 5.1.0
Matlab has lots of solvers for all types of families of differential equations. I think these are lacking (in their completeness and richness of documentation) in other programming languages ( at least this holds for R - much fewer solvers). I don't know how complete the Octave equivalents are.
knbknb··on This is for the fat ones: what changed it?
If you like to shop for food, buy higher-quality versions of everything. Buy the expensive fair-trade chocolate instead of the plastic bag of chocolate muffins, or the chocolate bar from the vending machine. Or go to a vegetarian restaurant instead of the burger chain.

These measures will reduce your budget for food, especially when your amount of money you can spend in a month is constrained. But you will eat higher quality ingredients and this alone will have a small beneficial impact on your body. Even if you do this to only a certain degree (you still buy junk food once a week, say) it will be beneficial, but more in a subtle way. You might even lose some weight this way, but don't expect too much.

Take a close look at "light" products or "fat reduced" products they are often more expensive and still contain _lower-quality_ ingredients. This also holds for many "vegan" products als well (margarine re-labeled as "vegan butter" for instance)

knbknb··on Alibaba acquires Berlin-based data Artisans for $103M
Software Engineering Radio has recently (Nov.2018) released an 1 hour long interview with Stephan Ewen, CTO of data Artisans: http://www.se-radio.net/2018/11/se-radio-episode-346-stephan...
knbknb··on What Foods Are Banned in Europe but Not Banned in the U.S.?
In Europe, the food industry can legally apply lots of food-altering measures from a large bag of tricks. To name a few: Foaming up stuff, adding water to add weight; using cheap low quality substitutes; removing bitter ingredients from decaying fruit by "steam-cleaning"; enzymes in the bread dough ...

In 2018 or 2017 they removed the import ban for high fructose corn syrup from the USA into the EU. Now HFCS making its way into many supermarket products.

knbknb··on Der Spiegel published around 60 stories from a fraudster
dw - Deutsche Welle. "Germqn Broadcast". https://en.wikipedia.org/wiki/Deutsche_Welle

A broadcast service for promoting the language and culture to an international audience. A bit like "Voice of America". DW is financed by public funds that was allocated on the state level (ARD).

The have offerings such as a "slowly spoken news with transcript" podcast, in German language.

knbknb··on 23andMe Informed Me My Husband and I Are Related
Here is the transcript of a recent, interesting audio podcast with Anne Wojcicki, CEO of 23andMe. https://www.recode.net/2018/10/20/18002614/anne-wojcicki-23a... I think what she argues in the podcast is quite reasonable.

Asked about the biggest mistake her startup made in the founding phase, she answered that " I think that we were overly optimistic about the state of scientific literacy in this country. "

And that is true in general. I live in Germany, I am a 23andMe customer, and from my results I learned quite a bit about myself. Locally, whenever I tried to talk about this genetic testing service, I have never had a deeper conversation about this subject matter, even with highly educated folks. It's similar to non-conversations about email encryption and IT security many of you readers might have had.

knbknb··on Haskell to Perl 6
I think this Haskell version (pugs) came at a time when perl6-development was somewhat stuck, and it enabled the Perl 6 developers to test new language constructs on an improved runtime (I believe); so Haskell was actually key to Perl 6 development. (https://gist.github.com/masak/479846/4908b28645b8815d1afe2b4...)
knbknb··on The Latest Crop of Instagram Influencers: Medical Students
I'm also from Germany, and going through some treatments right now (Surgery/Orthopedics) and I think this comment is too harsh. It overemphasises that some doctors may seem arrogant, or staff may have a negative attitude.

For instance Internet connectivity is not "catastrophically" bad, (could indeed be better, though).

An overlooked trend that has has changed communication patterns with patients for the worse is a trend towards larger joint practices with doctors as employees often not working fulltime. Joint practices tend to have larger, fuller waiting rooms, and which necessarily results in (in my experience) a more stressful doctor-visiting atmosphere.

Moreover, paperwork has become more complex also for patients, e.g. when agreements and waivers (for operations) have to be signed, nobody has the time to explain these. Nobody can explain finer points of medicine prescriptions, and usage of technical helping equipments (e.g. hearing aids). The staff at the front desk can't explain this, and the doctors do not have the time to either.

These are all general problems, not Germany-specific.

knbknb··on Google may shut down its news service in Europe
Is it the content-preview (however small), the content-gathering or the linking that will cost money?

Google could (re-)write the headlines and micro-summaries themselves (using machine-learning technologies) and just provide links, without copying anything from elsewhere for previewing purposes. Embedding no snippets and thumbnails at all from the media-/publisher websites would turn Google News into a text-only site, making it a lot less appealing to the audience.

knbknb··on Mark Shuttleworth is not selling Canonical or Ubuntu – yet
So, 125 Million US$ revenue / 566 employees = $221000 revenue / employee. Not bad for a software company.

According to my own personal regression analysis I did many years ago, a company is sustainable with at least $50000 revenue per employee. That's my personal ballpark number.

knbknb··on Ask HN: What are some of the best technical talks you've heard?
I like the talk by Ryan Dahl, node.js inventor

Original Node JS Presentation, 2009, https://www.youtube.com/watch?v=ztspvPYybIY

In 2018 he gave a follow-up presentation "10 things I regret about node", but that presentation is more for experts.

knbknb··on Forecasting: Principles and Practice
One of the authors, Prof. Hyndman, was also a moderator on stats.stackexchange.com .

knbknb··on Loneliness is pervasive and rising, particularly among the young
Maybe another influencing factor is parents who prefer that their toddlers only have contact with children of other parents who are somewhat like them. Thus, children are encouraged to create fewer friendships from an early age on.

The parents are not overprotective, or rather in a very specific way.

If that is so - (I'm just speculating here) - what we're seeing now is just the beginning of a trend that will continue for a very long time.

knbknb··on OpenAI’s Dota 2 defeat is still a win for artificial intelligence
Was the full list of heroes supported in theses showmatches? Or was this also restricted to a subset of, say, 15 out of 150 (or whatever that number is)?

The announcers/casters were a bit ambiguous about this, AFAIK they said something like : "the teams agreed on a predefined, balanced list of heroes before the game...", and there was no drafting.

(I'm not native speaker, and I don't know much about Dota2 rules)
