Deep Sea Correlation

  • For our features, we’re going to start with predicting Depth versus temperature, to see what we have there.
  • In order to validate our Regression models, as well as our baseline, we will use mean absolute error in tandem with R².
  • I chose to then investigate the mean of the TestX, and TestY, given that there is so much data here, I might consider going back and adjusting for a bigger train set, and smaller test set, because the test is sitting at about 250,000 observations, which is enormous, and just makes validation, and model exploration impossible to work with.
  • So looking at this, it’s pretty obvious that we need a different model to predict this.
  • We also see the reason why we had such a low mean absolute error, while also having such a low R² score, the model was predicting negatives.

Mother who cheated on son's ACT and tried to claim minority status gets 3 weeks in prison

  • Marjorie Klapper, a jewelry business owner who pleaded guilty to conspiracy fraud, is the eighth parent to be sentenced in the sprawling scheme to game the college admissions system.
  • Actress Felicity Huffman, who similarly paid $15,000 to cheat on her daughter's SAT test, began serving a 2-week prison sentence on Tuesday.
  • Parents Gordon Caplan, Marcia Abbott and Gregory Abbott were sentenced to 1 month in prison for test-cheating bribes, while Peter Jan Sartorio was given no prison time for the offense.
  • In addition, Klapper agreed to misrepresent her son as African American and of Hispanic/Latino origin on his college applications in an apparent attempt to claim minority status and further improve his odds of admission, according to prosecutor's sentencing memo.
  • Lelling said he disagreed with the 3-week sentence, given Klapper's bribe and her false claims about her son's race and origin.

Maintainability Through Colocation

  • There would be some serious problems we'd encounter by not co-locating our comments with the code it's explaining.
  • Now, you're probably thinking to yourself: "Yeah, duh, this is why nobody does this docs/ thing and everyone just co-locates their comments with the code.
  • This concept of file co-location applies great to unit tests as well.
  • I probably wouldn't go as far as putting the unit tests in the exact same file, but I don't totally rule that out as an interesting idea either (the implementation is left as an exercise to the reader).
  • I'm not saying don't bother unit testing complex utility functions (please do), but keeping them closer to where they're needed helps you avoid problems.
  • The same benefits of maintainability, applicability, and ease of use we get from co-locating our comments we get by co-location of other things as well.

Dodgy sex-psychology paper finally gets retracted

  • Now, four years after James Heathers and Nick Brown first started digging into Guéguen's work, one of his papers has been retracted.
  • One of those papers is the recently retracted high-heels study; the other was a study reporting that men prefer to pick up female hitchhikers who were wearing red compared to other colors.
  • The student provided an undergraduate field study report that is similar to Guéguen's 2015 paper on men's preference for helping women who wear their hair loose.
  • The retraction notice for the high-heels paper reports that it was retracted at the request of the University of Southern Brittany, Guéguen's institution.
  • Brown and Heathers also found some errors in the statistical tests, in which the results didn't match up with the data reported in the paper.

Russia removed US diplomats from a train near the site of a mysterious military testing accident

  • MOSCOW (Reuters) - Russia removed three US diplomats from a train near the site of a mysterious military testing accident on Monday because they did not have special permits to be in the area, the Interfax news agency reported on Wednesday.
  • Russia's state nuclear agency, Rosatom, has acknowledged that five of its nuclear workers were killed in an August 8 explosion during a rocket engine test near the White Sea in far northern Russia.
  • Interfax cited a source as saying that the US diplomats had been let go but are regarded to have broken Russian law.
  • In a report presented to the UN General Assembly this month, the US State Department said the nuclear accident near Nyonoksa, Russia, was caused by a nuclear reaction that occurred while Russians were attempting to recover a nuclear-powered cruise missile submerged in the White Sea after a failed test last year.

MCI: Should memory tests score males and females differently?

  • In the new study, the researchers scored memory tests using different norms and thresholds, or cut-off scores, for males and females.
  • From this data, the researchers calculated new norms and cut-off scores for males and females separately so that they could compare the application of these with results from the traditional scores.
  • The team then applied the traditional and sex-specific norms and cut-off scores to another set of results for the same verbal memory tests.
  • However, application of the new sex-specific norms and cut-off scores identified 10% false negatives, or previously missed cases of aMCI, among the females and 10% false positives among the males.
  • Markers of brain changes that happen in Alzheimer's disease, such as plaques of amyloid protein, were more advanced than normal in the females that the sex-specific scores identified as false negatives.

Autify raises $2.5M seed round for its no-code software testing platform

  • Autify, a platform that makes testing web application as easy as clicking a few buttons, has raised a $2.5 million seed round from Global Brain, Salesforce Ventures, Archetype Ventures and several angels.
  • The company, which recently graduated from the Alchemist accelerator program for enterprise startups, splits its base between the U.S., where it keeps an office, and Japan, where co-founders Ryo Chikizawa (CEO) and Sam Yamashita got their start as software engineers.
  • Users can currently test their applications using IE, Edge, Chrome and Firefox on macOS and Windows, as well as a range of iOS and Android devices.
  • Chikizawa, however, argues that Autify is different given its focus on enterprises.
  • He also stressed that Autify is able to do cross-browser testing, something that’s also not a given among its competitors.

UFC champion Jon Jones pleaded 'no contest' after being accused of assaulting a woman at a New Mexico strip club

  • Jon Jones has pleaded "no contest" to a charge of disorderly conduct after a woman accused him of assaulting her at a New Mexico strip club, ESPN reports.

  • On Tuesday, October 15, Jones stood before the Bernalillo County Metropolitan Court and pleaded "no contest" to a charge of disorderly conduct, ESPN said.
  • A plea of "no contest" in New Mexico is considered a "concession of the charge without admission of guilt," according to ESPN.
  • Jones received a 90-day deferred sentence, during which time he must avoid arrest, consume no alcohol or drugs, and make no contact with the accuser.
