Mahjong is like religion. The variant you're most comfortable with is the one you were taught. And no one can agree which is the best.

You should check out Knot dice, which is a fun tactile way to make one.

Naya's Quest is about how the isometric projection can mislead you. (Requires jiggering to get Adobe Flash to work)

The Arduino PID library write up covers more real-world instances such as derivative kick, and set point adjustment. Props to Brett Beauregard for documenting how the code evolves as features are added.

And where we get the word "verdant"
Red Delicious is now a grotesque betrayal of its original version and you know it.
Living situations for a large enough population will have statistical outliers. The students may not have the means of paying room and board.

The second generation of gear claims to have limiters to prevent nerve damage. Kinda like cars installing seat belts and air-bags.

Hopefully the design won't kill users on launch day.

Companies are also taking steps to limit liability due to the virus, which also depresses employment and spending.
Re:Bad Circuit Design on Wednesday June 10, 2020 @07:01PM (#23483189)
This website assumes you've studied CMOS circuit design for analog circuitry (amplifiers, analog-digital converters), and have the corresponding course book. It's a good list of when the linear model breaks down and you actually have to do the analysis.

I really like #3, placing a capacitor on a high-impedance node.

You'll have to factor economies of scale, shipping costs, mulitstep glass-blowing steps, and importation duties.

Finally, it's what the market is willing to pay.

Re:Reviewing Bad Schematics as EE Interview Tactic on Monday December 23, 2019 @10:28PM (#21869612)
That in itself is a Design for Manufacturing question, involving stack-up, Gerber correctness, and drill tolerances.

Dude, I work in RF and it would take me more than a minute to remember some of the answers to these questions.
Re:Ask HN: How many of you have been impacted by a layoff? on Sunday October 13, 2019 @10:18PM (#21244769)
Corporate office cancelled our core server hardware line. I saw the pallets of moving boxes come into the office the night before.

I took the opportunity to upload all of my work to the company servers and close out what tickets I could. Came into work the next day in a suit, trying to maintain some semblance of class.

Hardware development got reduced 66%, myself included.

Saw it coming in the nebulous sense, but the layoffs happened about 6 months before I was ready, since I wanted the last product release on my resume.

Took me almost a year before I found stable employment again. 1/10 would not repeat the experience.

Re:Show HN: Simple monthly passive income calculator on Saturday February 17, 2018 @11:23PM (#16404440)
Great tool, will have to show my family

Did you account for the principal also accruing value while you're saving up?

E.g. In the HY Savings account for a 1K/month passive income, you need $827,586. If you saved $1K/month, and reinvested that income until you got the $827K, it should only take you 20 years, not 23.

The error gets bigger when looking at longer time frames and higher returns.

Not quite sure if this is sarcasm...

Here's my counter-argument in case you were serious.

Dimwit #1: 555's fail when hell freezes over. An engineering intern can make changes and see it work. The PCB will cost more than the electronics. 555 as a component will be available for years.

Dimwit #2: Arduino/ATMEGA are so well documented that the next engineer supporting this should have no problem making appropriate changes even 10 years from now, assuming Microchip sustains the ATMEGA product line.

Senior Software Developer: You've introduced an attack vector [the web interface], increased the BOM cost [the Linux board], programmed it in a language that changes on a yearly basis [node.js]. Not to mention having to provide a Linux image source programmable [preferably eMMC], and ensuring compatibility of the web config for major browsers for the lifetime of the product. All for a blinking LED.

Odd definition of luxury goods, which makes me wary of the division of necessity vs luxury:

The Deutsche Bank Research report defined luxuries as “goods or services consumed in greater proportions as a person’s income increases” and necessities as those goods or services that make up a smaller proportion of spending as a person’s income increases.
