Serious question here. I was wondering whether C lends itself to obfuscation of undesired/malicious behavior or whether it is just the preferred language of people able to dream up such deviousness. Would someone with enough python-fu be able to pull this off or would the deception/error be easier to detect by the average coder? i.e. would an underhanded python contest be feasible or would the deception to readily apparent (or at least more apparent)?

Comment Dual boot linux problems? (Score 1) 203

I had difficulty installing Win10 on two dual boot machines. Both machines would throw up error messages of one kind or anther. Finally on whim, I removed dual boot capability by disconnecting the GRUB2 drive from one machine making the Win 7 drive the boot drive. I was then able to upgrade to Win 10. The other computer had both Debian and Win 7 installed on the same drive. I needed to use a live boot CD to remove GRUB followed by a boot repair procedure to allow the Win 7 partition to boot. This allowed me to update to Win 10. I then had to use a live boot CD to reinstall GRUB. Ugh.

Now both computers are upgraded to Win 10 and are back to dual boot machines.

Anyone else have problems upgrading dual boot machines to Win 10? Microsoft should allow people to trade in Win 7/8 product keys for Win 10 keys, preferably through a website.

Thank you for enlightening me. I read the wikipedia page on radiometers:

I learned that radiometers do NOT work by "light pressure" which was Crooke's, the inventor's, hypothesis. Radiometers do NOT spin in a perfect vacuum. The two mechanisms that explain why they spin were proposed by the likes of Einstein (relativity guy), Maxwell (equations guy), and Reynolds (number, not aluminum, guy).

Real question here-- I ask out of partial ignorance.

  How is this different from say using light, a form of electromagnetic radiation? Everyone has seen a radiometer (the thing with the black and white vanes that spins when in light. My thought experiment is if you have a directional light source that is pointed at a radiometer, that will cause the radiometer to spin, i.e. impart a thrust on the radiometer. That means there must be an equal and opposite force imparted on the light source. I would imagine this would work in a vacuum-- it is light after all. Isn't this another example of electromagnetic radiation (light) giving thrust?

Looking at the linked video, I was amazed to see the number of surrounding cars and objects being tracked. Also looking at the video, you could tell for almost a second that the trailing car was going to be a problem. Perhaps self driving cars that realize they are going to be rear ended could blink/flash lights, blow a LOUD rear facing horn, or something to catch the attention of the trailing driver.

Comment Please help put Flash down. (Score 1) 21

Given the endless stream of vulnerabilities and the treadmill of updating Flash, I decided to uninstall Flash. Given the hate that Adobe/Flash receives on Slashdot, I would imagine that a significant fraction of the Slashdot readership has uninstalled Flash (do you keep statistics on this?).

Can you please help the web move on from the failed experiment that was Flash?

Umm... Lets see. Fiorina's term as CEO ended in 2005. Hurd was CEO from 2005 till mid 2010. Apothekar takes over in mid 2010 and a year later Autonomy is acquired.


I'm no fan of Fiorina but it's a stretch to lay this on Fiorina. The acquisition was probably started under Hurd but Apothekar had a year to do due diligence and back out.


USGS: Oil and Gas Operations Could Trigger Large Earthquakes 171

sciencehabit writes: The U.S. Geological Survey (USGS) has taken its first stab at quantifying the hazard from earthquakes associated with oil and gas development. The assessment, released in a preliminary report today, identifies 17 areas in eight states with elevated seismic hazard. And geologists now say that such induced earthquakes could potentially be large, up to magnitude 7, which is big enough to cause buildings to collapse and widespread damage. Update: 04/23 15:56 GMT by T : New submitter truavatar adds: At the same time, the Oklahoma Geological Survey released a statement explicitly calling out deep wastewater injection wells to Oklahoma earthquakes, stating "The OGS considers it very likely that the majority of recent earthquakes, particularly those in central and north-central Oklahoma, are triggered by the injection of produced water in disposal wells."
