imakwana··on Ask HN: How can I learn macroeconomics properly?
This might be a specific aspect of Global Macro investing, but if you are interested in Risk Parity strategies (as popularized and adopted by Bridgewater), below two books by Alex Shahidi of Evoke Advisors cover Risk Parity asset allocation in great detail:

1) Risk Parity: How to Invest for All Market Environments

2) Balanced Asset Allocation: How to Profit in Any Economic Climate

imakwana··on Ask HN: Favorite Nonfiction Books of 2021?
Flash Boys by Michael Lewis
imakwana··on Ask HN: What is your biggest career mistake? What did you learn from it?
+1. It is paramount to pivot the personal career capital/skills to align with the industry trends. I have seen the stagnation take root in my own career currently, working in the same company for 6 years, and it indeed becomes exponentially harder to crack the interviews. The rest of the industry is far ahead of the curve compared to my current employer.
imakwana··on Ask HN: Skill you want to learn in 2022?
How to get better at technical interviewing, this is a skill that has cost me the most in terms of opportunity cost.
imakwana··on Ask HN: Does reading Hacker News makes you happy?
Yes, it is like walking into a coffee shop full of smart people and listening to their conversations. It is inspiring in a subtle and constructive way. The mental models acquired over many years of reading HN are extremely helpful in navigating the tech/career landscape.
imakwana··on Ask HN: Isn't keeping up with tech for your career same as “timing the market”?
An investment analogy can be "Core & Explore" portfolio of skills with pareto distribution (say 80% Core, 20% Explore).

The core skills are those that have stood the test of time over multiple decades (OOP, FP, Operating Systems, Distributed Systems).

The "Explore" portfolio is essentially venture capital like bet on new tools/frameworks/languages. Most of the venture bets will fail, but few of them will have exponential returns where you will get ahead of the rest of the market or discover early that your side-project/prototype is very valuable in the market (e.g. ML, Cloud services, etc).

imakwana··on Ask HN: Books that impacted your work that few other people seem to care about?
The Startup of You by Reid Hoffman and Ben Casnocha. There are lessons in this book which go far beyond conceptual origin of LinkedIn. There are network effects in labor market which can be systematically harnessed to accelerate one's career. It contains lot of those practices which are simple but not easy.

imakwana··on Ask HN: What would you like to see from portfolio aggregator?
From an asset allocation perspective, rebalancing triggers/alerts would be very useful. There are mainly two types: 1) Time based (monthly, quarterly or annually), 2) based on rebalancing bands such as 5/25 (i.e. 5% absolute deviation or 25% relative deviation).

Inside the Machine: An Illustrated Introduction to Microprocessors and Computer Architecture by Jon Stokes.
imakwana··on Ask HN: Career options for digital hardware engineer? Startup? Relocating?
My understanding, from US based hiring perspective, is that MS degree is purely for getting ahead of existing competition in the job market, to potentially stand out among vast pools of BS grads applying for the same position. Moreover, I also believe going through the formal degree helps later in career for rapidly learning new tools/frameworks/languages that is ever changing in industry. I might be biased though and sample size is very small (looking at Austin, Texas's hiring landscape).
imakwana··on Ask HN: Career options for digital hardware engineer? Startup? Relocating?
In a similar boat, currently a Design Verification engineer, planning to apply for Georgia Tech Online Masters in Computer Science (OMSCS) to get out of semiconductor industry and move towards to cloud-computing based software companies for future career growth. I am aware of few of my past colleagues who also followed similar path.
imakwana··on Ask HN: Which books made you the most money?
The Startup of You by Reid Hoffman and Ben Casnocha. It helped me in my early career right after graduation and influenced my career trajectory thereafter. I haven't lived up to the ideal that is set out in the book but it has been a guiding light.
imakwana··on Intel's disruption is now complete
> Semiconductor engineering is still a career suicide though, that haven't changed in the last few decades.

This is so true. I am currently a hardware engineer and planning to switch to software. If you are not in Nvidia, Apple or other mega-growth hardware companies, you are suffering atleast 40% paycut compared to software industry and also working about twice as hard, using obsolete tools and flows, and almost no opportunities for technical advancement or significant impact. Meanwhile the annual raises are cost-of-living adjustments. Its truly depressing.

imakwana··on Ask HN: Steady 4-5% on $5M?
Assuming that in order to preserve wealth you are targeting 4-5% safe withdrawal rate (including inflation adjustments), an all-weather portfolio or risk parity type of portfolios can serve this purpose well and designed to be very resilient and robust to different market environments.

imakwana··on Ask HN: How to get into the chip industry?
For learning below courses and books are very helpful:

1) Online courses: Computation Structures: Parts 1, 2 and 3 - all course materials available on EdX MIT as well as MIT OCW

2) Books: a) Computer Systems: A Programmers Perspective and b) Computer Organization: Hardware/Software Interface

3) Practice Verilog HDL programming for small/medium complexity building blocks such as FIFOs, RAMs, bridges, etc using free simulators like Xilinx ISIM. Courses such as Coursera's Hardware Description Languages for FPGA Design are a good starting point. Lookup most starred repos on Github in verilog and systemverilog languages.

imakwana··on RISC-V: What’s Missing and Who’s Competing
You have absolutely nailed it. Over the past 7 years, I have observed EDA tooling frustrating to the point that RTL design/verification/structural engineers in my $megacorp company abandoned this entire industry and move to software jobs. System-on-chip design industry desperately needs to adopt an open source EDA tool chain from architecture to synthesis and layout. Fortunately we have some amazing developments in this areas over the past year, specifically BlueSpec compiler becoming open sourced, SoC design and simulation framework such as ChipYard based on Chisel and Verilator. Lets hope this open source movement gains momentum and allows rapid innovation in this space.
imakwana··on Ask HN: What book/s do you recommend for learning computer architecture?

imakwana··on S&P 500 triggers 15-minute trading halt for the second time this week
Perhaps trend-line based approach that you described is similar to the strategy called "Value Averaging" which is a valuation based approach to averaging (instead of dollar cost averaging), where CAPE ratio or expected return is used to estimate long term trend.
