Small scale solar also doesn't make sense

But it only needs to make enough power to pay for itself, not to beat some hypothetical efficiency. I just need the panels on my roof to make enough electricity to pay for themselves over their lifetime. All the additional benefits (carbon emissions avoided, extra power beyond what pays for the panels, reduction in hot afternoon brownout risk) are just icing on the cake at that point.

Comment Read Marshall Brain's "Manna" (Score 1) 39

If you haven't read it, Marshall Brain's Manna is essential reading. The prophetic aspects of his dystopian view seem truer every day.

Slashdotters with good memories may remember Marshall Brain as the entrepreneur behind the "How Stuff Works" web site, which he sold for a fortune during the dot-com boom.

Submission + - How to find the Best Online Auto Parts Stores in Australia? (carpart.com.au)

franky20 writes: There are many online a1 auto parts in Australia, but not all of them are created equal. Here are some tips to help you find the best store for your needs: -

Check out the range of products on offer. A good store will have a wide range of parts and accessories available, so you can find everything you need in one place.

Make sure the store offers competitive prices. You should be able to find good deals on auto spares and accessories if you shop around.

Read customer reviews before making a purchase. This will give you an idea of the quality of service and products offered by the store.

Ask around for recommendations. If you know someone who has had a good experience with an online auto parts shop, they may be able to recommend a good one to you.

Submission + - Android Satellite SMS (arstechnica.com)

mspohr writes: "Snapdragon Satellite," a way to send satellite messages from a normal-sized Android phone. Unlike on the iPhone, this is real, two-way, SMS-style texting that you'll supposedly be able to use for more casual conversations instead of the iPhone's highly compressed, emergency-only, one-way questionnaire system that discourages composing a message.
Qualcomm's performance promises here seem good compared to Apple's solution. Grilli says you'll be able to send a "full-size SMS in less than 10 seconds, and on average, it takes three seconds." That's faster than the iPhone's 15 seconds for an emergency SOS, which is a highly compressed questionnaire message and not a full SMS. The iPhone is on a different Globalstar constellation with different characteristics. That Globalstar constellation has only 24 satellites covering the world, which is not good enough for continuous 24/7 coverage. These satellites are moving around, so there's a regular up-and-down cadence to the Globalstar service that lasts for minutes at a time for any given location. With 66 satellites in the Iridium constellation, you should always have service, and you might not even need to do that "hold your phone up" dance to get a connection.

Submission + - Terror Incident At Vegas Power Plant (8newsnow.com)

schwit1 writes:

Mohammad Mesmarian, 34, rammed his car through the gate of a solar power generation plant outside Las Vegas on Wednesday and set his car on fire, intending to damage a massive transformer, 8 News Now reported.

"Employees at the plant said they found a car smoldering in a generator pit," 8 News Now said, adding the Mega Solar Array facility provides power to 13 properties on the Las Vegas Strip, all belonging to MGM Resorts.

Investigators believe Mesmarian "siphoned gasoline from his car to put on wires at the transformer," 8 News Now said, citing documents from investigators.

"Mesmarian clarified he burned the Toyota Camry," police said. "Mesmarian said he burned the vehicle at a Tesla solar plant and did it 'for the future.'"


Submission + - 'Holy grail' wheat gene discovery could feed our overheated world (theguardian.com)

schwit1 writes: It has taken several decades but scientists at the John Innes Centre have now succeeded in their hunt for their holy grail. They identified the key gene, labelled it Zip4.5B and have created a mutant version of it, one that allows the gene to carry out its main function – to allow wheat chromosomes to pair correctly and maintain yields – but which lacks its ability to block the creation of new variants with attributes from wild grasses.

“A key tool in this work was gene editing, which allowed us to make precise changes in wheat DNA. Without it, we would still be struggling with this. It has made all the difference.”

Jones Innes scientists have since discovered that there are at least 50 different versions of Zip4.5B. “We are now going to test these in different varieties of wheat that we have created,” added Moore.

“These will then be grown in Spain, on land near Cordoba, to see how well they do. The aim will be to identify which varieties will do best at surviving the higher temperatures that our farmers are to experience in coming decades.

“Wheat has played a remarkable role in human history. Hopefully, this work will help it to maintain its importance as a foodstuff for the future.”

Submission + - The first orbital space launch from British soil will take off on Monday (npr.org)

tdsknr writes: The first orbital space launch from British soil is scheduled to take off on Monday.

A modified Boeing 747 airplane known as Cosmic Girl will take off from Spaceport Cornwall in England. Once it reaches 35,000 feet in the air, the converted aircraft will deploy a rocket, called LauncherOne, into space.

The LauncherOne rocket will deliver several payloads into orbit, including Wales' first satellite and the first ever satellite launched by Oman to observe Earth.

The article also wonders why companies like HPE don't just "dump some ISO files" onto an FTP server, along with patch depots and documentation. "This stuff has no commercial value, they're not losing any sales, and it will barely affect their bottom line.

Of course it costs them sales. If you keep old devices on life support, you're not buying new HP Z workstations or Elitebooks or whatever that run Windows or Linux.

Comment Re: Who hates OOP? (Score 1) 386

The situation you describe is a failure to design a solution to the required problem domain, not a failure of OOP. If brake sensors have certification requirements that fuel sensors do not, then clearly those requirements need to be reflected in the design of the code and the way the basic "pressure sensor" object is extended to specific certification-required tasks.

If the problem is that nobody knew there was a requirement, then it doesn't really matter what programming paradigm you use, the risk is still present. The risk is that the requirement wasn't captured, and that will impact any code.

Comment Physics? (Score 1) 74

Nothing he said makes sense in the context of physics. GPS satellites are 1-ton, 1000-watt devices (solar panels produce 1136 watts when first deployed) with a 500W transmitter, that are launched to an orbit of 11000 nautical miles. That's the high end of "Medium Earth Orbit (MEO)", so they can receive from a larger portion of the planet and spend more time outside the Earth's shadow.

If he thinks he can replace GPS with 12-kilogram satellites launched to LEO, he's on hepped up on spaceballs or something.
