soundsop··on American Indian tribes thwarted in efforts to get coronavirus data
> I fear the erosion in trust between the public and public health agencies is causing permanent damage in our abilities to mitigate future disasters

No, it just means communities/towns/cities/counties/states should not cede responsibility to the bureaucratic organizations.

I think this pandemic will make us safer in the future because local authorities will not trust the WHO or the CDC and move forward with their own planning and actions.

soundsop··on Books I recommend to my software engineering students
My list for all engineering students:

Design of Everyday Things Founders at Work Antifragile

soundsop··on Britain has abandoned its claim to be the world's fifth largest economy
True.
soundsop··on Britain has abandoned its claim to be the world's fifth largest economy
> max size of the economy is linearly tied to population

> why China is going to be on top

India will have a larger population than China (http://statisticstimes.com/population/china-vs-india-populat...) so it should end up on top.

soundsop··on The Nobel Prize in Physics 2017
Me too, although I recognized his name because I read his book Black Holes and Time Warps: Einstein's Outrageous Legacy. That was over 20 years ago.

soundsop··on How to Get Your Apartment Off the Grid
Electricity derived from solar panels and stored in batteries is neither free from cost nor free from carbon emissions. The monetary cost and emission of carbon coincides with the manufacture of the solar panels and batteries rather than the generation and storage of the energy unlike many other technologies.

The costs and emissions of solar-derived electricity may be lower than alternatives but they are most certainly not free.

soundsop··on Marvin Minsky, 1927-2016: the death of a genial skeptic
In general, I like the idea of aggregating the discussion. I will miss how the front page would fill with links about someone who passed away.
soundsop··on Show HN: Print iconic patents for your walls
I created a page at https://society6.com/constantchaos where these can be ordered as prints.

I was so intrigued with the drawings that I started to look for additional patent drawings to add. My favorite new ones are the Gameboy patent drawing and 3 drawings related to Curta mechanical calculators.

I developed my own vectorization and re-rasterization process that I believe offers a slight improvement in faithfulness to the original drawing (took a few tries to get the Curta ones right).

soundsop··on Tarsnap: No heartbleed here
The older posting that is mentioned, which is called Securing an HTTPS Server is a good read: http://www.daemonology.net/blog/2009-09-28-securing-https.ht...
soundsop··on What Heartbleed Can Teach The OSS Community About Marketing
Akamai was notified and completed the patch in advance of public disclosure according to their Heartbleed FAQ: https://blogs.akamai.com/2014/04/heartbleed-faq-akamai-syste...

This raises the question about whether Amazon/AWS was notified prior to public disclosure.

soundsop··on Why I Dropped Dropbox and got OwnCloud
Have you considered the AeroFS (https://www.aerofs.com/pricing)? I have not used AeroFS, but it would be on my list to evaluate for your use case, especially if external storage is undesirable. Pricing seems in line with Dropbox for Business, although this does not take into account the cost of maintaining your own storage.
soundsop··on CPU reliability – Linus Torvalds (2007)
You are correct. I want to clarify that the failure process is electromigration, not electron migration. It is caused by electrons but it is ions in metal that migrate. Wikipedia has a good description: https://en.wikipedia.org/wiki/Electromigration.

I design integrated circuits and one of the constraints in selecting the width of wires is to make sure that the maximum current density is below the electromigration threshold.

soundsop··on H1B Visa Lottery for FY 2014
They do. See http://www.visapro.com/Immigration-Articles/?a=1090&z=48

The first 20,000 applicants with an advanced degree from a US institution have priority.

soundsop··on Pentium-III autopsy
I am a circuit designer and SEM cross-sections are quite commonly used by transistor device designers during design and debug. They also appear in papers about transistor device design. A relevant conference is International Electron Devices Meeting and the related journal paper is IEEE Transactions on Electron Devices. Unfortunately, most of those papers are behind the IEEE paywall.

Chipworks is a company that reverse engineers chips for analysis by competitors. Their websites has lots of cool SEM cross-sections: http://www.google.com/search?cx=w&q=chipworks+SEM&tb...

Even though I design circuits using these devices, I still find the SEMs mindblowing.

soundsop··on Grade inflation: why weren’t the instructors all giving all A’s already?
When I went to grad school in engineering and became a TA, I found out there was a guideline for the undergraduate class average from the department. It was actually presented as the historical class average for informational purposes, with standard deviation, but the implication was that a professor's class average should be close the the historical average.
soundsop··on Why I will never pursue cheating again
It sounds like the course marking scheme is broken.

In my engineering courses (both as a student and TA), assignments were worth very little, or sometimes not handed in at all, and were instead a tool for the student to learn the coursework. Marks were largely based on quizzes, midterms and finals (usually worth 80 to 90% of the course grade). It's not an ideal solution, as there are skills that cannot be tested in these conditions, but it eliminates the need to spend time on detecting cheating on assignments. Of course, it is important to prevent cheating during examinations, but this is a much more tractable problem.

They could also test you on some of the less-recognized words you selected to help identify cheating.

soundsop··on N is a Number : A Portrait of Paul Erdős
The biography of Paul Erdős, The Man Who Loved Only Numbers, is a great read. http://www.amazon.com/Man-Who-Loved-Only-Numbers/dp/07868636...
soundsop··on Paul Graham is right (using AVC’s data)
If p is bimodal, then p = 2*p1 is not possible. Either p = 0 or p = 1. The values in between do not occur.

Then the only thing to quibble over is G. But if you believe p = 1 for a company, what's the point of quibbling over G?

soundsop··on "God's Number" is 20 - Rubik's cube has been "solved"
I see that cube21.org also resolves to the same site, so I guessed they hedged their bets.
soundsop··on New Amazon Kindle announced: $139 WiFi-only, $189 3G, available August 27th
I can't tolerate the jarring flash to black (pixel reset) that occurs when changing pages on e-ink devices. Has this limitation been overcome?
soundsop··on Costly IRS 1099 Mandate Slipped into Health Bill
It is amazing to me how many critical aspects of an open democracy are dependent on rules of house/congress/parliament.

This sort of unrelated/obfuscated clause insertion and the 60-vote requirement to defeat a filibuster are two prime examples.

Will there have to be constitutional amendments saying1) bills must be clear and address only one topic, and 2) simple majorities shall always rule, expect in pre-specified cases, and no parliamentary rules shall override simple majority in letter or in spirit.

Memory ECC won't help if computations are incorrect.
soundsop··on Inside Apple's automatic graphics switching
Interesting that the system switches between two distinct devices at different power/performance points. There is probably some redundancy here, in that the higher power/performance (discrete) GPU likely includes all the elements of the simplified (integrated Intel) GPU. So the discrete GPU could be designed in a way that dials down the power and performance to match the discrete CPU. I know Intel and AMD CPUs include voltage/frequency/power-gating dials for selecting a power/performance point, but I don't know if GPU engines make heavy use of these features.

The simplified GPU being integrated with the CPU probably saves some power from not having to go off-chip to talk to each other. This power savings might be what justifies having two distinct devices.
