  >> The 2-3 weeks I worked on Git to get that started for example. 
His side-project, kicked-off in 2-3 weeks :). This would be a lifetime project for most people.
blacksmythe··on What the heck is a parser-combinator?

blacksmythe··on What's Y Combinator's conversion rate?
Not sure that the conversion rate is the most important metric.

  >>  Y Combinator... creates more than a billion dollars of value with each class it graduates...
blacksmythe··on We analyzed thousands of interviews on everything from language to code style
The data suggests that it is easier for a C++ programmer to get make a good impression in a non-C++ shop, than at a C++ shop where they likely to test you on C++ edge cases.

Interesting that this effect does not show up for Java programmers.

  >> expensive, hard-to-source hardware engineering skills.
If only that were true.

Lots of hardware engineers have moved into software.

blacksmythe··on Paul Buchheit on Lessons Learned from Investing in 200 Startups

  >> When you sell too early you don’t realize the full potential.
For every company you can find that sold too early, I can probably find 10 companies that had a good chance to sell that they should have taken.
blacksmythe··on Crowdfunding platforms crack down on risky campaigns

  > >This has been true of so many Kickstarter projects, but has hit hard goods especially. 
People with software backgrounds sometime struggle transitioning their skill set to hardware problems. Often the hardware problems turn out harder than expected.

As someone with an EE/hardware background, though, I am deeply impressed at the efforts that succeed, sometimes surprisingly well.

blacksmythe··on Ask HN: Conversation Sparkler App

  >> give you news or trivia related to those things to help you out.
Should the app be named CliffClavin?
blacksmythe··on Why Quantum Computers Might Not Break Cryptography

  >> We can't even get people off SHA1 to SHA2 "because of lower performance." Somehow I doubt the "1 terrabit RSA key" would go over well with them.
So apparently we are going to need quantum processors to generate encryption that is resistant to quantum processors.
blacksmythe··on Don't tell people to turn off Windows Update
I switched my family from Windows to Linux at home because of the work involved in keeping a working Windows machine (with minimal user supervision) connected to the internet.
blacksmythe··on Why Amazon is eating the world
Amazon used to be a very dependable market for quality goods, but you can no longer depend on getting a quality product.

I find Costco on-line to be a very credible Amazon alternative. Costco now fills the niche that Amazon did 2 years ago.

blacksmythe··on Uber hit by legal setback in Europe

  >> have to gains shipped off to billionaires in California?
Uber is operating at a loss. Presently the gains are being shipped from billionaires in California.

blacksmythe··on Machine Learning FAQ
some discussion points:

   Fitting a model via closed-form equations vs. Gradient Descent vs Stochastic Gradient Descent vs Mini-Batch Learning – what is the difference?
   How can I avoid overfitting?...
blacksmythe··on Ask HN: Critique my company

  >> Any ideas how we can get feedback from our new developers on how to improve?
Hire outspoken developers. Dan Luu would be an excellent choice:

blacksmythe··on Speck-Size Computers: Now with Deep Learning

    "The idea is to bring neural networks to the Internet of Things. 
    A lot of motion detection cameras take pictures of branches moving in the wind—that’s not very helpful”
blacksmythe··on The Utter Uselessness of Job Interviews

  >> admit when they don't know something... encourage you to validate that with data
Correlating this with employee performance data might not be the only metric.

My experience is that people that won't admit they don't know something are not necessarily bad employees. Often they are capable employees, although this is a trait I rarely see in the best employees. However, I find they are toxic to a good work environment, since they won't listen to people who do know something.

They do seem to get promoted to management had a much higher rate :)

blacksmythe··on Textbook manifesto (2016)

  >> re-read a text book about a year after I had finished the class...
  >> it really helped me deepen my understanding of the topic generally.
As an endorsement of this comment, 'ChuckMcM has the deepest/broadest knowledge of an enormous range of hardware/engineering issues of anyone I am familiar with who posts frequently on HN.
blacksmythe··on Shenzhen is a hothouse of innovation
What was your path to getting started?

(from beginner to being able to make basic conversation)

blacksmythe··on Shenzhen is a hothouse of innovation

  >> I was motivated enough to spent 7+ months learning basic Mandarin
That is impressive.

I have tried learning Mandarin, and found that in the same amount of time that you could be communicating (at a very basic level) in another language (even one considered 'hard' like Japanese), with Mandarin I am still trying to get tones right.

blacksmythe··on Shenzhen is a hothouse of innovation

  >> early programmable logic (PALs and PLDs) were easy to program with available documentation.
FPGAs now are much easier to use now than early programmable logic (PALs and PLDs). You can do 10x more than you could before (about 1990 IIRC), in 1/10th the time.

The main thing that has shifted is that the bar is higher. 10x more than an early PALs/PLD design is not worth much today.

blacksmythe··on Oscilloscope pong for 1 or 2 players

  >>  I've done the "flip the chip over, super glue, and solder wire wrap wires to the leads" but its not fun.
Depends on your idea of fun, but this is a pretty standard way of breadboarding analog/RF circuits. (not used much as PC board fab has gotten so fast and cheap)

I have done it many times, and I think it is fun :)

blacksmythe··on State of the Seed Market in 2017
Cute tongue in cheek reply.

  >> planting three avocado pips
If you search on "planting avocado seeds", the first page of results are on how to plant them, with little discussion of why not to plant them.

“Ungrafted” trees (like those grown inside from seeds) rarely produce fruit. In order to have an avocado tree that produces fruit, one must graft the seedling."

blacksmythe··on How much your computer can do in a second

  >> It is astonishing how fast a computer is without the overhead most modern languages bring in.
The other interesting thing with high level languages (using Python as an example) is that a small number of features that are not often used keep the language from running significantly faster (see PyPy for example).

Seems like there should be room for a language with slightly reduced set of Python features (Py--) which runs much faster.

blacksmythe··on Tech Interview Torture Chamber

  >>  I have given up entirely on interviewing for SV companies, and work 100% remote now.
Most of the people that I know that work remotely have preferred to work for SV companies, because they pay substantially more. What has your experience been?
blacksmythe··on Are We Different People in Different Languages?
I probably am. My wife could tell if I was speaking English or Japanese on the phone based on my body language.
blacksmythe··on Learn Python 3 the Hard Way

  >> Coursera course by Martin Odersky
Brilliant course.

Unfortunately, the next one in the series is not nearly as good.

blacksmythe··on Cloudflare Reverse Proxies Are Dumping Uninitialized Memory

  >>  top-tier reward of a t-shirt.
A t-shirt still seems entirely too small; closer to insulting than motivating.
