oldbuzzard··on HackMIT 2017 Admissions Puzzle
Just looks like a login page to me. No way to see either info on your event or your clever puzzles w/o giving up my personal info :(
oldbuzzard··on Cash for Math: The Erdős Prizes Live On
From the article, I think the "remaining money" may be entirely notional. It talks about Ron Graham chipping in $5k to help cover a $10K bounty.

Besides, these days the money is mostly beside the point. It is like those Knuth reward checks, https://en.wikipedia.org/wiki/Knuth_reward_check. In most cases, certainly the most recent $500 "happy ending" problem, the bragging rights are worth more than the money.

oldbuzzard··on Geometric Constructions Game with Straightedge and Compass
It would be nice to be able to move or get rid of the task completed box to review your solution and look for modifications. Then you could reset and replay. The inability to review after completing is annoying.
oldbuzzard··on Amazon Restaurants
Meh. I have prime and keep getting $10 off coupons but here in Minneapolis I don't see anywhere I want to order from. Bitesquad has places that I order from every now and then. If Amazon had a decent network they might entice me in to becoming a restaurants customer... but as it is, it is like the crappy prime video selection.

oldbuzzard··on Ask HN: Anything Like Carl Sagan's Cosmos for Computer Science?
Gleick's "The Information" and Dyson's "Turing's Cathedral" would be 2 other good pop sci books on the origins of CS.

oldbuzzard··on Ask HN: Who are the other Elon Musk's?
Craig Venter
oldbuzzard··on Weapons of Math Destruction (The Dark Side of Data Science)
The article addresses that a couple of paragraphs down. Thats her whole point.To quote:

"The Nation at Risk report that started it all turned out to be bullshit, by the way -- grounded in another laughable statistical error. Sandia Labs later audited the findings from the report and found that the researchers had failed to account for the ballooning number of students who were taking the SATs, bringing down the average score.

In other words: SATs were falling because more American kids were confident enough to try to go to college: the educational system was working so well that young people who would never have taken an SAT were taking it, and the larger pool of test-takers was bringing the average score down."

oldbuzzard··on This Is Your Life in the Midwest
Wow! My life in the Minneapolis strongly resembles my former life in Seattle. I have walkable/bikeable neighborhods, good local restaraunts and food coops/farmers markets, etc etc

The problem isn't the Midwest, it is suburbia. I've know contractrs at MS like in the article. Plenty of folks in Boston or Northern Virginia or RTP are living in the far suburbs and working in unsatisfying jobs they aren't good at... nothing to do with the Midwest.

oldbuzzard··on We’re in a Low-Growth World. How Did We Get Here?
The Center for Economic Policy Research has a great free pdf ebook on Secular Stagnation from 2014 which has essays from a variety of economic heavyweights discussing the possibility of lower growth going forward.

oldbuzzard··on Emperor Akihito of Japan Raises Possibility of Leaving Throne
How so? Most of these are explicitly apolitical

The monarchy didn't help with Brexit. I suppose it could help broker coalition governments in a parlimentary systems... though Thailand certainly shows how overly broad lese majeste laws and and strong military can have the opposite effect at least with regards to national unity.

oldbuzzard··on Amazon's Chinese Counterfeit Problem Is Getting Worse
Well Yes. That's the irony. If you had even minimal trademark enforcement, the risk ratio would encourage you to manufacture and sell white label and counterfeit jackets as separate firewalled vendors. So one could be shut down without effecting the other. Here the risk is clearly so low they don't even bother... or maybe they have firewalled vendors and the cost of setting up a generic vendor is so low that its less than the dual manufacturing pipeline... either way that's the irony.
oldbuzzard··on How to Raise Brilliant Children
>The first, basic, most core is collaboration.

Particularly ironic since the 2 authors previous book was "Einstein Never Used Flash Cards"... and Einstein managed to publish brownian motion, photo electric effect, and special relativity during his annus mirabilis in 1905, while working at the patent office... no collaboration involved just lots of deep thought.

oldbuzzard··on The Sad Story of Heisenberg's Doctoral Oral Exam (1998)
Sort of a more high stakes version of the Grothendieck "prime"... makes you wonder how many more folks haven't made it through the gauntlet.
oldbuzzard··on Which Hollywood movies feature the most ridiculous code?
Jurassic Park with that weird 3-d graphical tree file system and the girl geek exclaiming roughly "Cool, its Unix!" gets my vote.[1]

oldbuzzard··on Facebook Blocks Internet Pioneer “R.U. Sirius”
Before the Snowden stuff... mmm probably yes.

I'd bet that quote comes from an old issue of "Mondo 2000" and is contempory with the Clipper Chip battles about mandated NSA backdoors in all telecoms circa '93/94.

oldbuzzard··on Who's Actually Buying iPods These Days?
The 240/320gb iPod Classics were insanely popular with DJs and other music folks until Apple cancelled them and still have a strong resale market.

While that may not constitute a viable commercial niche, it does suggest a use case among a tech savvy community.

oldbuzzard··on MGH launches phase II trial of [100yo] BCG vaccine to reverse type 1 diabetes
I've seen BCG described as cave man immuno-therapy for bladder cancer and other apps... it will be interesting to see how it works for diabetes and MS.

Presumably someone has looked at rates of those types of diseases in Eastern Europe, where BCG was used a a vaccine for TB for years.... but I have no idea if it worked preventitively.

oldbuzzard··on Ask HN: What are your recommended reads that are available for free?
Feynman Lectures on Physics

oldbuzzard··on How Suburban Are Big American Cities?
Circa 2008, lots of areas around Greenwood didn't have curbs or sidewalks... everything north of 85th got annexed by Seattle in the 50's and none of it had sidewalks or curbs or storm drains. I bet most of the other sidewalk-less areas are similar annexations.
oldbuzzard··on Inventing an algebraic knot theory for eight year olds (III)
DS8 and I have recently been enjoying Christopher Zeeman's[1] Royal Institution Christmas Lectures[2]. The first one on linking and knotting has the same flavor as the article and could be a good intro for parents doing this at home.

oldbuzzard··on Watson in the Wild: Brewery Master
The site doesn't fail gracefully... if it can't populate fields it just keeps the previous entries.

I'm in Minneapolis and if I look at a brewery and then look at Dangerous Man, it can't find the beer list so it just keeps the listing for Harriet or Fulton or whoever I clicked on before. For a spotlight app that is a pretty glaring bug...

oldbuzzard··on What Books Could Be Used to Rebuild Civilization?
Kevin Dunn's "Caveman Chemistry"[1] is a fun book.

Instructions for tinkerers "for making bronze from metal ores; glass from sand, ashes, and limestone; paper from grass or straw; soap from fat; alcohol from honey; photographs from egg whites; chlorine from salt water and celluloid from cotton."[2] among other things.

oldbuzzard··on Math from Three to Seven: Chapters One and Three [pdf]
Alexander Zvonkin's book is worthwhile both for math pedagogy and Soviet insight... the OP doesn't link the full book... either http://www.ams.org/bookstore-getitem/item=MCL-5 or http://www.amazon.com/Math-Three-Seven-Mathematical-Preschoo... is a great example of a preschool Math Circle.

If math pedagogy is your main interest any of the MSRI Math Circle Library books are worthwhile. This includes "Circle in a Box" which is a Math Circle starter kit freely available here http://www.mathcircles.org/GettingStartedForNewOrganizers_Wh...

oldbuzzard··on What if Finland’s great teachers taught in U.S. schools?
As to income viability...

The large government run National Household Education Survery which is the best data available shows little difference in homeschool and public income demographics. Over the last 4 surveys('99,'03,'07,'11) homeschoolers have had ~20% in poverty and 50+% within 200% of poverty.

http://www.responsiblehomeschooling.org/homeschooling-101/ho... is a decent summary of the data with links to the most recent Department of Education surveys.

http://www.responsiblehomeschooling.org/wp-content/uploads/2... is a single graph of the above data from 2003

oldbuzzard··on Ask HN: How much screen time do you let your kids have?
The problem is that some "interactive stuff", like Farmville and Candy Crush and to some degree Angry Birds, is more similar to a Skinner Box than any true interactive environment. Books and puzzle are much less likely to push those buttons.

Also I think there is a worthwhile kinesthetic element on puzzles that is lost online. That could vary from learning to precisely line up puzzle pieces to other things. For instance my younger DS enjoys both the ipad and physical versions of Rush Hour/RHjr. Honestly, setting up the board in physical version is more of a sequencing challenge than solving the puzzles... I know... that makes no sense... however I've seen it again and again. The physical version teachs a superset of the sequencing, planning, and visual skills of the app.

oldbuzzard··on James Watson to be the first person to sell his Nobel Prize
This is offensively pedantic. If you can't see the difference between donating medals for war relief and selling them personal gain then nothing I can say will help.

Bohr and Kroghs actions are inspiring. Gunter Blobel donating his entire monetary reward for rebuilding cultural artifacts in Dresden is laudable... I have no doubt other science laureates, Pauling(?), have generously used the Nobel resources for humanitarian purposes.

Selling your medal for personal gain is just crass.

PS. For more on Bohr, Nazis, and Nobel's check this out.. http://www.npr.org/blogs/krulwich/2011/10/03/140815154/disso... Dissolving and later recasting prizes to keep them from Hitler is pretty cool.

oldbuzzard··on Ask HN: Looking for a dense book on algorithms
On the other hand if you like wordy, I would quite recommend "Compared to What"[1] by Rawlins...

[1] http://www.amazon.com/Compared-What-Introduction-Algorithms-...

oldbuzzard··on Ask HN: Looking for a dense book on algorithms
OK. So Cormen's "Intro to Algorithms"[1] or Knuth[2].., but be prepared to be gobsmacked and have a graduate level math background...

oldbuzzard··on How I Rewired My Brain to Become Fluent in Math
I found the article rambling and mostly pointless...

However, if you have a weak background in math and want to get up to speed before going into calculus and beyond, I have 2 suggestions.

1) Lial's Basic College Math[1] is adequate and will get you up to speed. 2) Serge Lang's "Basic Mathematics" is great and will cover all you need to go into a rigorous theory based college math class.

[1] http://www.amazon.com/s?ie=UTF8&field-keywords=lials%20basic... The editions basically the same... pick the cheapest
