California’s public colleges to no longer require students to know math or read

12:40 pm

The coming dark age: California’s public universities have decided to drop its requirements that all in-coming students be able to do basic math and be able to read and write English.

Cal State will no longer make those students who may need extra help take the standardized entry-level mathematics (ELM) exam and the English placement test (EPT).

The new protocol, which will go into effect in fall 2018, “facilitates equitable opportunity for first-year students to succeed through existing and redesigned education models,” White wrote in a memorandum to the system’s 23 campus presidents, who will be responsible for working with faculty to implement the changes. The hope is that these efforts will also help students obtain their degrees sooner — one of the public university system’s priorities. Cal State has committed to doubling its four-year graduation rate, from 19% to 40%, by 2025.

…“This will have a tremendous effect on the number of units students accumulate in their first year of college,” said James T. Minor, Cal State’s senior strategist for academic success and inclusive excellence. “It will have an enormous effect on college affordability, on the number of semesters that a student is required to be enrolled in before they earn a degree, and it will have a significant impact on the number of students that ultimately cross a commencement stage with a degree in hand, ready to move into the workforce, ready to move into graduate or professional school.” [emphasis mine]

In other words, the university has no interest in producing graduates with any useful skills. All the university wants to do is to give them a degree, so that they can claim success. Under this new policy, students incapable of reading and writing English and doing math will still be able to take normal courses that require such skills the moment they enter college. They will likely be pushed through the system, given passing grades, so that when they graduate, they will be like the characters in the movie Idiocracy, functionally illiterate but expected to run society as college educated elites.

SES agrees to a second Falcon 9 launch with used first stage

6:46 pm

Capitalism in space: SES has agreed to launch a second commercial satellite using a previously flown Falcon 9 first stage.

The launch of the SES 11 spacecraft, also named EchoStar 105, will be the third time SpaceX has sent a customer’s satellite into orbit with the help of a reused rocket stage. Industry officials said SES, EchoStar and SpaceX agreed in recent weeks to shift the satellite from an all-new rocket to one with a previously-flown first stage. The SES 11/EchoStar 105 satellite will likely ride a Falcon 9 first stage that first flew Feb. 19 with a Dragon supply ship heading for the International Space Station, one source said, but a firm assignment has not been confirmed. That vehicle returned to a vertical touchdown at Landing Zone 1 at Cape Canaveral Air Force Station.

Liftoff from a Florida launch pad is scheduled no sooner than around Sept. 27, a couple of days after a United Launch Alliance Atlas 5 rocket is set to haul a classified payload into orbit for the National Reconnaissance Office, the U.S. government’s spy satellite agency.

The most wonderful aspect of this is how routine it is steadily becoming.

One of Jupiter’s mid-sized storms

One of Jupiter's mid-sized storms

Cool image time! The Juno image on the right, cropped to show here, focuses in on one of Jupiter’s mid-sized storms near its high northern latitudes and just on the edge of the chaotic polar region.

This storm is a long-lived anticyclonic oval named North North Temperate Little Red Spot 1 (NN-LRS-1); it has been tracked at least since 1993, and may be older still. An anticyclone is a weather phenomenon where winds around the storm flow in the direction opposite to that of the flow around a region of low pressure. It is the third largest anticyclonic oval on the planet, typically around 3,700 miles (6,000 kilometers) long. The color varies between red and off-white (as it is now), but this JunoCam image shows that it still has a pale reddish core within the radius of maximum wind speeds.

Be sure to take a look at the full image, which provides a bit of context.

International group forms to get UN protection of Apollo sites

8:43 am

An international group of lawyers, academics, and business people has formed an organization called “For All Moonkind,” aimed specifically at getting UN protections for the six lunar Apollo sites.

They are going to the UN because, based on the Outer Space Treaty, this is the only place that has jurisdiction. Unfortunately. This quote illustrates why:

“Though we are based in the US, we are an international organization,” said Michelle Hanlon, US space lawyer and Co-Founder of For All Moonkind. “Humaid Alshamsi [the UAE participant] brings tremendous experience in public and private aviation and space law to our team. We are thrilled that he has agreed to join our effort.”

For All Moonkind was critical of the auction by Sotheby’s of the Apollo 11 Contingency Lunar Sample Return Bag used by astronaut Neil Armstrong. “The astronauts of the Apollo project represented all of us here on Earth,” explained aviation and space lawyer and Advisory Council Member Humaid Alshamsi, “they went to the Moon in peace for all, and the relics of their historic achievement should be shared by all. The loss of this artifact to a private collector is a loss for humanity.”

The Outer Space Treaty forbids any nation from claiming territory in space, thus leaving it under the control of the UN and the international community, a community that — as demonstrated by this quote — is hostile to capitalism and private enterprise. While I laud this group’s desire to protect these historic sites, I fear their actions are going to place limits on the freedoms and property rights of future space colonists.

MU69 is not round

5:43 pm

New data about 2014 MU69, the Kuiper Belt object that New Horizons plans to fly past on January 1, 2019, suggests that it is either elongated or made of two objects almost touching.

Recent observations suggest that the rock is no more than 20 miles long, and its shape is not round or elliptical, like most space rocks. Instead, the icy body is either shaped like a stretched football, called an “extreme prolate spheroid,” or like two rocks joined together. That creates a rubber ducky shape similar to the comet that the European Space Agency landed on two years ago.

It’s even possible that the object is, in fact, two objects — like a pair of rocks that are orbiting around each other, or are so close that they’re touching. If 2014 MU69 does turn out to be two objects, then each one is probably between nine and 12 miles in diameter, according to the New Horizons team.

I predict that this object will be even weirder in shape that predicted. The low gravity in the Kuiper Belt almost guarantees it.

Some Amazon Echo speakers can be hacked to spy on you

9:39 am

Some of Amazon’s Echo speakers, designed to listen and record conversations if so commanded, can be hacked to record everything and transmit those recordings remotely.

First of all, you have to have actual access to the device to mess with its hardware. Then, you have to make sure it’s either a 2015 or 2016 model, as brand new Echo versions can’t be hacked similarly.

But if these conditions are met, then a hacker can quickly take the Echo’s base apart and load on it custom firmware that will instruct it to record everything spoken around it. That data can then be sent out to a remote server. That’s what Barnes did in his security tests. Hacking a home speaker may be the best way to spy on certain targets, even if this implies infiltrating their homes to actually mess with the hardware.

This is why I want nothing to do with smart machines. The dumber the machine, the better. I see no reason for my speakers, my washing machine, my car, or my stove, to be connected the internet. All such capability provides is a way to cause problems.

Aetna to withdraw from all Obamacare exchanges

9:22 am

Finding out what’s in it: Aetna has decided to withdraw from all Obamacare exchanges, after seeing its profits increase when it reduced its participation partly last year.

Aetna has been gradually withdrawing from the Obamacare exchanges. It had decided to pull out of the exchanges in other states because it lost $700 million between 2014 and 2016 and was projected to lose $200 million in 2017 despite having already significantly reduced its participation in the exchanges to only four states.

A disproportionate number of unhealthy customers have signed up for the exchanges, which provide tax subsidies to pay for insurance, causing unbalanced risk pools for many insurers. Aetna also has cited uncertainty over the future of the law and over whether it will receive federal payments as a contributing factor to its decision. [emphasis mine]

The highlighted words illustrate the fundamental problem with the Obamacare law. It forces insurance companies to take on sick people who had failed to buy insurance before they became sick. Such an insurance model is unsustainable. Insurance works because enough people buy it before they need it, thus helping to fund those who need it. If everyone can wait until they need it then there is no pool to fund any payouts, and the insurance company goes bankrupt.

As is happening with Obamacare.

New images downloaded from Curiosity for the first time in two weeks

9:15 am

For the first time since communications with Mars ceased two weeks ago because the orbits of the Earth and Mars had placed the Sun in between, new images have been downloaded from Curiosity.

For the past two weeks, the last raw images posted had been from sol 1760. Today, the Hazard Avoidance Cameras (Hazcams) added daily images through sol 1774 (taken as per previously uploaded commands). The images all show the same view, the part of Vera Rubin ridge that the rover has been circling around to get to the place where it will be easier to climb up. The science team probably programmed this sequence so that they could look for any changes from wind, over time.

No new images from either Curiosity’s other cameras or from Opportunity have yet appeared, but I expect this to soon change.
