Comment Blue Book Test (Score 1) 160

I never really felt that any of the research papers I did 15 years ago were all that impactful in what I actually learned in college. Really all it takes for a professor to make sure students are actually learning the material is to make written, in-class tests/quizzes the majority of the grade- something like 80 - 100% of the grade. I remember many of my upper level college classes were blue book essay tests that had to be done in the span of 90 minutes and open ended diagramming, reasoning, or math problems.
That doesn't solve grading the 300+ student classes without incurring additional cost overhead of needing more grad students to grade though. I think the biggest problem is that many professors at many universities would rather not be teaching at all, so they go with the minimum required effort when it comes to evaluating theirs students.

Submission + - Florida journalist raided, computer seized, in unauthorized access investigation (miamiherald.com) 1

FriendlySolipsist writes: Independent journalist Rebekah Jones, a scientist fired by the Florida state government because, she said, of her refusal to manipulate official COVID-19 data releases to coincide with political considerations and who now operates web site floridacovidaction.com, had her home raided by the FL state police who seized computers and cell phones, the Miami Herald reported. The FDLE affidavit in support of the raid was published by the Herald — https://www.miamiherald.com/la... — and asserts that an unauthorized internal message was sent to the "ReadyOps" system within the state Department of Health from an IPv6 address associated with the Comcast account at Jones residence.

How a Tiny Bit of Lacquer Grounded New Falcon 9 Rockets For a Month (arstechnica.com) 21

On October 2, SpaceX automatically aborted the launch of a Falcon 9 rocket (with just two seconds left in the countdown) after two of its first-stage engines ignited early. Investigating the problem ended up delaying the October 31st launch of four astronauts to the International Space Station until November 14, reports Ars Technica, citing a teleconference with SpaceX's Hans Koenigsmann.

"Had the abort not triggered, it is likely that nothing bad would have occurred, but Koenigsmann said that under certain extreme scenarios, rattling from an early ignition may cause significant damage to the Merlin engines." SpaceX technicians removed the two engines and shipped them from Florida to the company's test site in McGregor, Texas, where they were able to replicate the problem. They found that a relief valve within the gas generator — a tiny rocket within the engine that starts up and powers its machinery — was clogged with a masking lacquer akin to nail polish. They were able to show that removing the lacquer from the vent hole allowed the engines to start up normally. This lacquer is applied during an anodizing process to treat aluminum components of the gas generator. It is supposed to be subsequently removed, but in the case of these two engines, a tiny amount of the material had been trapped within a bore hole less than 2mm across...

After this, SpaceX inspected other engines across its fleet (the company inspected new boosters only, as Falcon 9 first stages that have already flown are not subject to this issue). SpaceX found that two of the engines on the Falcon 9 rocket that will be used for the Crew-1 launch also had this problem. Those two engines are now being swapped out for new Merlins...

This lacquer issue came as a surprise given that SpaceX has literally launched hundreds of new Merlin 1D rocket engines over the last decade and, until now, had not seen this problem with the masking agent. "It's certainly possible that we had cases of it earlier, and they were appreciably so harmless that we completely missed them," Koenigsmann said. It is also possible that a small process was changed so that all of the lacquer was not removed, as this particular treatment is done by an outside vendor. But, he admitted, "It's difficult to explain how this works for so many years and then, suddenly, you see this coming up in the data."

What Koenigsmann seems confident in is that the issue will not occur again.

Hulu, AT&T To Test 'Pause Ads' In 2019, Automatically Playing Commercials When You Hit Pause (macrumors.com) 188

An anonymous reader quotes a report from MacRumors: Streaming TV services offered by companies like Hulu and AT&T are testing the waters for a new type of advertising called "pause ads." The idea behind pause ads is that instead of facing forced commercial breaks at specified interludes, users would be more accepting of ads that play when they choose to pause a show for a bit while they do something else. Hulu says it plans to launch pause ads in 2019, but not much else was given in the way of details regarding which of its numerous streaming plans will include the new type of commercial. The plan likely to see pause ads is Hulu With Limited Commercials, which interjects a few ads throughout a show's runtime, similar to live TV, but again this hasn't been confirmed.

AT&T cited similar interest in pause ads, stating that it also plans to launch technology in 2019 that plays a video when a user pauses a TV show. For both companies, it's unclear exactly how long these ads will run for, and if you'll be able to immediately cancel them out by simply hitting the play button and resuming your TV show. According to Hulu vice president and head of advertising platforms Jeremy Helfand, pause ads will not be home to longform advertisements, but will instead focus on commercials where advertisers "have seconds" to deliver a message effectively. Over the next three years, Hulu expects "more than half" of its advertising revenue to come from these so-called non-disruptive experiences.

Comment When an Excel based macro is requested... (Score 1) 202

... and the user refuses to allow me to code the tool in Python I've found that putting everything in VBA is a great rule of thumb to protect the users from themseles- no formulas on the spreadsheet, at most static, locked data as a way to store configuration. Be sure to incorporate a custom set of error handling that allows the code to be easier to debug. Make the macro fire upon opening with user-friendly set of forms that allow whatever parameters (file upload, settings, ect). Output calculated data to a new spreadsheet and close the macro when it's done so that user doesn't have a chance to alter the macro.

So, in otherwords using VBA and ditch the spreadsheet helps a ton.

All of that said... I'd still rather be using Python, R, Javascript or anything else over VBA.

CIA 'Siren Servers' Can Predict Social Uprisings Several Days Before They Happen (sociable.co) 174

Through a combination of machine learning and deep learning, the Central Intelligence Agency (CIA) is using powerful supercomputers, dubbed "Siren Servers" by computer philosophy writer Jaron Lanier, to predict social unrest days before it happens. The Sociable reports: CIA Deputy Director for Digital Innovation Andrew Hallman announced that the agency has beefed-up its "anticipatory intelligence" through the use of deep learning and machine learning servers that can process an incredible amount of data. "We have, in some instances, been able to improve our forecast to the point of being able to anticipate the development of social unrest and societal instability some I think as near as three to five days out," said Hallman on Tuesday at the Federal Tech event, Fedstival. The CIA deputy director said that it was "much harder to convey confidence for the policymaker who may make an important decision from advanced analytics with deep learning algorithms." Now that the CIA claims to be able to predict social unrest days in advance, there are some interesting theoretical possibilities that can come of this. One is that the CIA's siren servers will become so efficient that they will predict all social uprising and will be able to prevent it. If they are successful in doing that, there would be no need for the CIA as their technology could predict and prevent any societal upheavals, and the agency would be obsolete. Another potential outcome would be that the CIA could use the data and not tell anyone, just like the finance sector did, and then make calculated decisions on whether or not to intervene in any socially distressing situation.

Submission + - Apple CEO Likens Surface to Car That Flies, Floats

theodp writes: Conceding that he hadn't actually played with one, Apple CEO Tim Cook told Wall Street that Microsoft's Surface tablet is 'a fairly compromised, confusing product' in the company's 4Q earnings call. Cook joked, 'I supposed you could design a car that flies and floats, but it wouldn't do those things very well.' In Apple's 2Q earnings call, Cook also mocked the idea of touch on a laptop or desktop, quipping, 'You can converge a toaster and a refrigerator, but those things are probably not going be pleasing to the user.' Cook added, 'We've done tons of user testing on this, and it turns out it doesn't work. Touch surfaces don't want to be vertical.' So, is Cook just pulling a page from Steve Jobs' people-don’t-read-anymore playbook, or is he unaware that children happily used vertical touch screens forty years ago on UIUC's PLATO System (more PLATO History)?

Submission + - Mother Found Guilty After Protesting TSA Pat-down of Daughter (tennessean.com)

Penurious Penguin writes: In 2011, en route to Baltimore, Tennessee mother Andrea Abbott was arrested after squabbling with the TSA over their pat-down and "naked" body-scan process. Initially Abbott had protested a pat-down of her 14 year-old daughter, though eventually backed off. When her own turn came, she refused both a pat-down and body-scan. This week, despite having no criminal record, Abbott was found guilty of disorderly conduct and sentenced to one year of probation.

A surveillance video of the affair shows what appears an agitated Abbott surrounded by various TSA agents, but seemingly contradicts the premise by which she was convicted. In the case against Abbott it was claimed that her behavior impeded the flow security-lines and lawful activity. Beyond Abbott's confession of issuing some verbal abuse, the video does not appear to display a significant blockage of traffic nor anything noticeably criminal.
