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.

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 + - '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.”

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.

Citizens Against Government Waste outlines seven criteria by which spending can be classified as "pork":

  • Requested by only one chamber of Congress
  • Not specifically authorized
  • Not competitively awarded
  • Not requested by the President
  • Greatly exceeds the President's budget request or the previous year's funding
  • Not the subject of Congressional hearings
  • Serves only a local or special interest.

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.

if your servers go down, YOU can fix them immediately

Spoken like someone who has never had to fix a server immediately :-)

One of the strong points of cloud computing is the infrastructure to shift load to accommodate failing hardware. To reproduce that capability with your own hardware & infrastructure requires a tremendous amount of planning and capital investment: in power, servers, and network. It's almost never a simple matter of "fix the server immediately".
