tkyjonathan··on Corporate debt nears a record $10T, and borrowing binge poses new risks
> 2007-2008 era financial crisis revealed that the bankers are incompetent at assessing risk.

They are not incompetent at assessing risk. That is entirely their job.

It was that the government intervened in the housing market and to do so, assumed risk from the 1993 Clinton initiative to offer minorities access to mortgages and purchase their own homes.

Mozilo from Countrywide exploited this.

tkyjonathan··on What is energy, actually? (2011)
All countries in the world pursue growth. Forcing them to reduce their energy usage, is a non-starter.

Your best bet would be to reduce the energy consumption of things and have more power sources that have no CO2 emissions like hydro-electric and nuclear.

tkyjonathan··on Is Inequality Inevitable?
And what exactly gives your money compound interest?

Its not like everyone has access to something that offers that..

tkyjonathan··on Is Inequality Inevitable?
Yes, we are all different.
tkyjonathan··on Apple commits $2.5B to combat housing crisis in California
Not to get into a protracted argument, but I do not see this as democracy (or capitalism). I see this as socialist top-down elements in a mixed economy.

As a comparison, you have councils (or soviets) deciding for people, how they conduct their economic activity - in this case, not allowing them to build apartments on land they own.

If you are hoping for a top-down control AND it be enlightened for-the-people AND democratically given this control, then you are looking at the wrong governing model. Especially, if you don't believe that top-down won't benefit at some point tiny interest groups.

> A failure of both democracy and capitalism.

What are you talking about?

It was the Californian governing body that isn't allowing developers to build new cheap homes and apartments, because of NIMBY.

And at the same time, everyone is talking about the evil tech giants, so they are trying to look good. If they would just be left alone, they might spend their resources on - oh, I dont know - making cheaper and better phones so that more people around them world could afford them?

tkyjonathan··on Apple commits $2.5B to combat housing crisis in California
I wonder if that money will be purely to pay for lobbyists against NIMBY.
tkyjonathan··on Lifetime Earnings Are 40-50% Heritable
I have a feeling that this is going to include things like IQ and then we will get into a big racist mess.
tkyjonathan··on Ask HN: Is there a better way to document complex software architectures?
There is a very good way to document software architectures:

I use BPMN 2.0 with DMN

Look it up, see what you think.

tkyjonathan··on New Study Indicates Silicon Valley’s Elite Are Not as Liberal as They Think
Maybe this site should do a survey: How many conservatives friends and co-workers do you know?
tkyjonathan··on The Google Cemetery – A list of dead Google products and why they died
I miss igoogle...
tkyjonathan··on Rust and SPARK: Software Reliability for Everyone (2017)
Used in electronics, I think.
tkyjonathan··on How We Built a Cost-Based SQL Optimizer
Hear, hear
tkyjonathan··on Engineers Shouldn’t Write ETL
In 4 weeks, I was able to create a data mart that had self-healing (we had issues with Python/events missing data which should have reached the existing data warehouse) and the physical data models in it sped up an existing 6 hour ETL task down to 0.15 seconds AND speed up a production query that took 5 seconds per click down to 0.07 seconds.

No team needed or proof of concepts. Actual working data models, up to date tables + ETL code in production.

Background is DBA.

tkyjonathan··on Engineers Shouldn’t Write ETL
ETLs, physical data modelling and data marts/warehouses used to be handled within database admin's task in small to medium sized companies and largely with ETL tools or just SQL.
tkyjonathan··on Philosophy Has Made Plenty of Progress
The reason why philosophy is not keeping up is that there are 'misintegrating' frameworks with in it that take it down the wrong track and can no longer integrate new concepts into it.

But you have that problem in science too like quantum mechanics, string theory..

tkyjonathan··on Philosophy Has Made Plenty of Progress
Philosophy is the study of concepts. To get to something purely theoretical, you need to abstract the precepts of your original concepts. Then it becomes a floating abstraction.

Take for example Einstein: he found some mathematical formulas, proved they were right and then used them as the abstraction for everything else. His example of 'what if I stand on a train traveling at the speed of light and it gets hit by lightning' is no longer something that you can prove in reality.

Ideally, you need precepts and concepts to work together and keep validating that your concepts work in reality.

tkyjonathan··on Philosophy Has Made Plenty of Progress
Philosophy is the study of concepts and you can have philosophy of science.
tkyjonathan··on Philosophy Has Made Plenty of Progress
A bit off-topic, but philosophy has a huge underground following now. Even I started to get into philosophy of systems (general systems theory) as well as pure topics like epistemology, ethics, aesthetics and logic.

If you are out of Uni and never learnt it while in Uni, I recommend looking into Objectivism.

tkyjonathan··on Progress in Philosophy
I dunno.. I'm studying on my own philosophy of systems (general systems theory) and I find it incredibly useful for my line of work. Perhaps philosophy can progress when applied to other fields, like biology, computer science, quantum physics...
tkyjonathan··on Using AWS EC2 instance store vs EBS for MySQL
RDS doesn't fail over to a slave anyway. You would need to do that manually.

If you mean 'I ticked the multi-az box' that is only in the even that the AWS datacenter crashes - it will move RDS for you to another zone. If you have services that cache ip addresses from DNS, you will need to rediscover the database.

tkyjonathan··on Why Can't We Hate Men?
Doesn't the Washington Post have some sort of policies against 'hate speech'?

I mean.. this kind of qualifies as that.

tkyjonathan··on The Decline of the MacBook Pro
They will pry my MacBook pro out of my cold dead hands!
tkyjonathan··on Queryparser, an Open Source Tool for Parsing and Analyzing SQL
You know.. any Data Architect would have done this sort of data governance task for you. You wanted to know which tables where join'd on and which group by's were the most popular? welcome to a concept called query digest from >11 years ago. Sorry, but all I am hearing is 'how can we burn money on a pet haskell project using a team of devs that will forever need to maintain it'. Have the right expert do the right job..
tkyjonathan··on Turning web design mockups into code with Deep Learning
Would be nice if this was in some adobe product. Then you can go from illustrating straight to web site.
tkyjonathan··on What If Sugar Is Worse Than Just Empty Calories?
I don't think you went over that medical summary I provided: Fatty acids do not serve as fuel for the brain, because they are bound to albumin in plasma and so do not traverse the blood-brain barrier. In starvation, ketone bodies generated by the liver partly replace glucose as fuel for the brain.
tkyjonathan··on What If Sugar Is Worse Than Just Empty Calories?
Depends how much you cut back. I think your body/brain needs 120g of glucose a day. https://www.ncbi.nlm.nih.gov/books/NBK22436/
tkyjonathan··on Brain inflammation sows the seeds of Alzheimer’s
"Long-term effects of a ketogenic diet in obese patients".. read the first line. Its 16-24 weeks. Thats not exactly long term. Also, the study was done for people at home, not in a clinical ward.

Try this 8 year study instead https://www.ncbi.nlm.nih.gov/pubmed/20592131 Or if you want a long term RCT, try this 74 week one: https://www.ncbi.nlm.nih.gov/pubmed/19339401

tkyjonathan··on Brain inflammation sows the seeds of Alzheimer’s
Thats not true. Western diet is build on processed foods - which includes lots of processed sugars and processed fats together.

Example, I don't see people eating teaspoons of white granulated sugar all day long.

Doughnuts and ice-cream on the other hand...

tkyjonathan··on Brain inflammation sows the seeds of Alzheimer’s
There are a number of fallacies in your statement. 1) Western societies are large populations that eat meat and eat meat more than other large populations, by far.

2) Inuits live 10 on average less than the local nearby populations and 900 year old Inuit mummies also show signs of advanced osteoporosis.

3) Processed sugar is not a health product and is not the polar opposite of meat. It is in the same category of meat as 'unhealthy' and 'causes inflammation'

4) A whole-foods low-GI plant-based diet has been show to open up arteries and that is important for Alzheimers as people with that disease do show blocked arteries to the brain post-mortem. So while not a 100% prevention, it certainly reduces risk and may even reverse issues.
