Submission + - F-35A Catches Fire at Mountain Home Air Force Base (defensenews.com)

theweatherelectric writes: Writing for Defense News, Valerie Insinna reports that another F-35 has caught fire during an exercise. She writes, "The incident took place at around noon and involved an F-35A aircraft from the 61st Fighter Squadron located at Luke Air Force Base, the service said in a statement. No serious injuries seem to have been sustained by the pilot or nearby crew.

'The pilot had to egress the aircraft during engine start due to a fire from the aft section of the aircraft,' Air Force spokesman Capt. Mark Graff said in an email. 'The fire was extinguished quickly. As a precautionary measure, four 61st Aircraft Maintenance Unit Airmen, three Airmen from the 366th Maintenance Group and the 61st Fighter Squadron pilot were transported to the base medical center for standard evaluation.'"

Submission + - Ask Slashtot: How to determine if your IOT device is part of a botnet? 1

galgon writes: There has been a number of stories of IoT devices becoming part of
Botnets and being used in DDOS Attacks. If these devices are seemingly working correctly to the user how would they ever know the device was compromised? Is there anything the average user can do to detect when they have a misbehaving device on their network?

Submission + - New formula massively reduces prime number memory requirements.

grcumb writes: Peruvian mathematician Harald Helfgott made his mark on the history of mathematics by solving Goldbach's Weak Conjecture, which every odd number greater than 5 can be expressed as the sum of three prime numbers. Now, according to Scientific American, he's found a better solution to the Sieve of Erasthones:

In order to determine with this sieve all primes between 1 and 100, for example, one has to write down the list of numbers in numerical order and start crossing them out in a certain order: first, the multiples of 2 (except the 2); then, the multiples of 3, except the 3; and so on, starting by the next number that had not been crossed out. The numbers that survive this procedure will be the primes. The method can be formulated as an algorithm.

But now, Helfgott has found a method to drastically reduce the amount of RAM required to run the algorithm:

Helfgott was able to modify the sieve of Eratosthenes to work with less physical memory space. In mathematical terms: instead of needing a space N, now it is enough to have the cube root of N.

So what will be the impact of this? Will we see cheaper, lower-power encryption devices? Or maybe quicker cracking times in brute force attacks?

Comment Re:Curly braces = good. Indents = bad. (Score 1) 173

I have dyslexia, and severe issues with telling whether things are vertically or horizontally aligned. Curly braces are much, much more useful than horizontal indentation for me; I imagine people with more severe visual impairment would have even worse issues. (I can configure my editor to do vertical greenbar for the background, but that's a hack that only works in my local environment.)

Submission + - Firefox 49 Postponed One Week Due to Unexpected Bugs (softpedia.com)

An anonymous reader writes: Mozilla has announced this week that it is delaying the release of Firefox 49 for one week to address two unexpected bugs. Firefox 49, which was set for release on Tuesday, September 13, will now launch the following Tuesday, on September 20.

Work on fixing the two issues is ongoing. The first is a problem with a slow browser script, which is also the most time-consuming issue since the Mozilla team needs around a week of telemetry data to evaluate the fix. This is also the primary reason they've delayed Firefox 49 in the first place. The second problem relates to loading Giphy GIF images on Twitter, which open in a new blank page instead of the Giphy URL. This issue was first detected in Firefox 49 Beta releases.

Firefox 49 is an important release in Mozilla's grand scheme of things when it comes to Firefox. This is the version when Mozilla will finish multi-process support rollout (a.k.a. e10s, or Electrolysis), and the version when Firefox launches the new WebExtensions API that replaces the old Add-ons API, making Firefox compatible with Chromium extensions.

Submission + - SPAM: Health Care Providers Scramble to Meet New Disaster Readiness Rule

schwit1 writes: "The new rule is aimed at preventing the severe breakdown in patient care that followed disasters including Hurricane Katrina and Hurricane Sandy, while also strengthening the ability to provide services during other types of emergencies, such as pandemics and terrorist attacks."

How good will the requirements be? "At least some of those provisions were significantly modified in the final version. Chief among them was a proposal that hospitals and nursing homes test their backup power systems for a minimum of four hours every year at the full load needed in an emergency, rather than the current standard of once every three years. Generators have failed catastrophically in hospitals and nursing homes around the country during prolonged power outages, endangering patients and leading to chaotic evacuations. However, the government removed the enhanced testing proposal, stating that there was not enough evidence it 'would ensure that generators would withstand all disasters.'"

Well, nothing will ensure that. But why is four hours per year too much to expect?

Submission + - SPAM: China To Resurrect The AN-225

schwit1 writes: On August 30, members of the Aviation Industry Corporation of China (AICC) and the Antonov Corporation, the leading Ukrainian aviation company, signed an agreement to restart production of the AN-225, the world's largest cargo aircraft.

The 640 ton, six engine An-225 is the world's largest aircraft. Measuring at 84 meters in length and a wingspan of over 88 meters, it carries a world record payload of 250 tons (to put this into comparison, it can carry around 300,000 lbs more than the US military's Boeing made C-17). The sole operational An-225 began flying in 1988, initially carrying the Soviet Buran, a 105 ton reusable spaceplane, on its back. It was put into storage after the Soviet collapse, but restored and put into commercial service in 2002. Since then it has been rented out, flying super heavy cargos like gas and wind turbines, as well as military supplies for NATO forces in the Middle East.
