sadfaceunread··on Human-Powered Helicopter Wins the $250,000 Sikorsky Prize
Pretty cool result. I'd wonder what the performance would be with ~150 lb of batteries, motors and electronic sensors/controllers instead of a human. I wonder if given the same mechanics of this system a human is the optimal motor just because of the built-in automation and control system (probably not).
sadfaceunread··on Yelp Hipster Finder
Kinda interesting but I wonder if it is normalized at all for the yelp review density in a given area. See xkcd: http://xkcd.com/1138/ as I draw some unusual correlations in the Boston maps.
sadfaceunread··on Disappointing Unsealing Decision in Aaron Swartz Case
Another perspective: http://tech.mit.edu/V133/N26/swartz.html Swartz's lawyers initially sought complete release of information with no redaction of identifying information (including SSNs and Birthdates see: Pre-motion statements and the actions regarding maintenance of certain records they were obligated to destroy at the end of the prosecution). Clearly balance is needed and the employees of the victims in a criminal prosecution (JSTOR, MIT) deserve reasonable protection.

edit: Minor increase in clarity, re:reply

sadfaceunread··on Got accepted in an accelerator. What kind of visa?
You are screwed. This is way way too little time to get your visa situation in order. Consult an immigration professional immediately to have any hope of success.
sadfaceunread··on MIT supports release of Swartz case documents, if redacted for employee privacy
This is not a particularly accurate title. MIT could release the records at any point (they are MITs to do with whatever they please), and in fact already committed to do so once redaction had occurred.

MIT actually expressly opposes in this document the Keker & Van Nest LLP proposed modification of the protective order, without redaction. And in fact brings up a serious procedural misconduct of Keker & Van Nest LLP (they should have already destroyed any copies they possessed already because the criminal case was fully concluded).

sadfaceunread··on Letter from MIT President on Releasing Aaron Swartz Documents
Some actual reporting on this issue besides just the letter from the MIT President can be found at http://tech.mit.edu/V133/N13/swartz.html

Apparently JSTOR also supports redaction: " JSTOR’s response was similar to MIT’s. “We believe the information we provided to the United States Attorney’s Office in this case should be made open and available to the public. In a letter dated Feb. 25, we agreed to the lifting of the protective order so long as the articles downloaded from JSTOR were not released and the identities of our staff are protected,” said Heidi McGregor, a JSTOR spokeswoman, in an email to The Tech. “We do not agree that individuals’ names need to be included with these materials to serve the public interest.” "

" “Although the United States and representatives of Mr. Swartz agreed on many proposed modifications to the ­order, the United States and Mr. Swartz’s representatives did not reach agreement on the scope of the redactions,” Pirozzolo said.

“The United States expects to respond to the motion within the time provided by the district court rules,” he said. “It will also request that individuals potentially affected by the modification of the order be given an opportunity to be heard on the proposed modifications.” "

Given that last part you can certainly expect the MIT documents to come out much much faster than Gov documents.

sadfaceunread··on Letter from MIT President on Releasing Aaron Swartz Documents
He almost surely has gathered a team to help with the paper shuffling and related activities required to produce a large investigative report.

Everything else that has ever been said indicates that the report will be out in 2013. If you look carefully , (;)) you can find some Abelson quotes on the web discussing this.
sadfaceunread··on The 50 million dollar lie
+1.

The blog author saying there is no clear trend in his random blob of points is misleading. The trend is there, it is just difficult to tell the density of points in his scatter plot because of the marker size and plot size.

sadfaceunread··on Aaron Swartz's Lawyer: MIT Refused Plea Deal Without Jail Time
Insider here. Almost all legal representation and interactions of the Institute flows through the Office of General Council.
sadfaceunread··on MIT and Aaron Swartz
As a member of the MIT community, I honestly do not feel very bad about how MIT (Administration) handled this situation. MIT's tradition of careful and thoughtful rule breaking clearly recognizes that rules will be enforced and that the police may be involved in criminal matters.

MIT does not and should not decide prosecution strategy. This was not a civil case, but a criminal prosecution in the American tradition of criminal justice. The victim is not the one prosecuting the crime but rather the government prosecutes on behalf of all people, not on behalf of the victim exclusively.

So this is ONLY on Kindle devices? Do kindle targeted apps suffer from an inability to use google/bing?
sadfaceunread··on Scientists build the first all-carbon solar cell
Actually this is I believe the second published all carbon solar cell.

First one came out of MIT http://web.mit.edu/newsoffice/2012/infrared-photovoltaic-062...

sadfaceunread··on Texas Students Revolt Against Mandatory RFID Tracking Chips
So if this is being used to track attendance what is to stop someone from just carrying their friends id for the day through the EZ-pass at the entrance?

If a student lobs their id over the fence, then walks out of the campus is the system going to think they were at school all night?

Seems very problematic to implement an EZ-pass style system.

sadfaceunread··on Shin Mochizuki has released his long-rumored proof of the ABC conjecture
This paper is 4th in a sequence. There is a mistake on page 59 of the third paper according to some other math blogs. Not sure how this may impact other results subsequently.
sadfaceunread··on Ask HN: Apple closed our entire app store
Post the termination notice in full perhaps?

How many apps went down? Did you violate iTunes/App Store T+C in some noticeable way? Finally, did you violate someone elses rights copyrights, trademarks, intellectual property such that they may have sent a demand letter to Apple?

Perhaps in retrospect, having all the apps tied to a single entity was a bad service for your clients representing a single point of failure.

sadfaceunread··on Show HN: We allow teachers to print out "Scantrons" and scan for results via fax
This is one of the most interesting companies I've seen posted on HN in a while. Good luck achieving market penetration.

I'd put up a pdf of a generated assignment that can be scan/fax graded online right away in an easy to access fashion. That is what I most wanted to take a look at, and it looks like the demo won't render the document.

Do you put a QR code on each assignment to uniquely identify a student? So papers have to be handed out precisely to each student? Or do you have students bubble in names/identification numbers?

How are you going to handle the kind of problems that would be created by using this technology in a class of <8th graders? Crumpled/dog eared papers, intentional attempts to make forms hard to computer read. Have you thought about linking to Amazon's Mechanical Turk to have human grading of difficult to parse entries?

Is your product going to be crushed by computers/tablets for every student in future classroom environments? If assignments are all digital (i.e some college textbook environments like 'Mastering Physics') the scan to grade edge slips out. Especially when providers can offer prewritten educational material questions/exams/content as part of their platform.

sadfaceunread··on 3 caculators = 3 different answers to one math problem
Comments on the original post indicate that if you do 6/7(1+2) then you get 2 as well and the iPhone is just throwing away whatever digit is in the position of the 7.
