Ask Slashdot: Best Anti-Virus Software In 2015? Free Or Paid? 467

CryoKeen writes: I got a new laptop recently after trading in my old laptop for store credit. While I was waiting to check out, the sales guy just handed me some random antivirus software (Trend Micro) that was included with the purchase. I don't think he or I realized at the time that the CD/DVD he gave me would not work because my new laptop does not have a CD/DVD player.

Anyway, it got me wondering whether I should use it or not. Would I be better off downloading something like Avast or Malwarebytes? Is there one piece of antivirus software that's significantly better than the others? Are any of the paid options worthwhile, or should I just stick to the free versions? What security software would you recommend in addition to anti-virus?

Submission + - This Battery Has Lasted 175 Years and No One Knows How (vice.com)

sarahnaomi writes: There sits, in the Clarendon Laboratory at Oxford University, a bell that has been ringing, nonstop, for at least 175 years. It's powered by a single battery that was installed in 1840. Researchers would love to know what the battery is made of, but they are afraid that opening the bell would ruin an experiment to see how long it will last.

The bell’s clapper oscillates back and forth constantly and quickly, meaning the Oxford Electric Bell, as it’s called, has rung roughly 10 billion times, according to the university. It's made of what's called a "dry pile," which is one of the first electric batteries. Dry piles were invented by a guy named Giuseppe Zamboni (no relation to the ice resurfacing company) in the early 1800s. They use alternating discs of silver, zinc, sulfur, and other materials to generate low currents of electricity.

Journal Journal: After Several Months Not Bothering 5

I visit a few threads here, on reasonable topics - like Barrett Brown case, etc.

The level of discourse has really troughed. It's like "conversation" between the Dufflepuds..

It's not worth even trolling these people. There isn't enough signal-to-noise for this to even register.

he's giving advice that doesn't implicate him in anything, in an on topic comment

he doesn't owe you anything, so say "thanks"

or say nothing

or reveal the only real character defect in this thread, which is not being a bragging dipshit, but yours: loudmouth asshole begging for a pointless fight

and that pointless fight will find you someday. you'll mouth off like you just did, because you wrongly think it makes you superior, to the wrong character, and depending on how badly you lose the resulting conflict, you'll probably be thinking:

I get the quantum mechanics principle, the mere act of observing changes the observed, that you can't measure the momentum or the position without affecting the other. But, just put a telescope in the orbit and it changed the universe? ... come on guys, there should be some limits even on hyperbole.

I change the universe all the time. Of course, most of it will never be affected by those changes, but changes they are.

Comment Re:Like the destructive scanning (Score 1) 163

I wonder if anyone's tried combining some sort of sintering process with an electron microscope... it would be neat to be able to build up a complete molecular model of an object and then be able to reproduce it, layer by layer. It'd take forever, but you could replicate some pretty useful things really accurately. And once you've destructively scanned the item once, you can replicate it as much as the materials you have on hand allow. Great for making backups of mechanical parts, just in case someone stops making that specific part. Not so good if you don't get the printing accurate, as you'd have a part with stress lines most likely.

Comment Re:Prototyping security? (Score 2) 163

Only problem with that is: if you can replicate an object with this contraption, you can replicate the object using a similar contraption that doesn't contain the destructive/encryption element. So if the item ever leaves a secured area, anyone can replicate it.

So yeah; it could be used to send a key to a remote location... but you could just keep the plan for the key in an encrypted file and send that to whoever you want -- as you still can in this situation (anyone with the file and the key can replicate the item at any point in time).

Researchers Moot "Teleportation" Via Destructive 3D Printing 163

ErnieKey writes Researchers from German-based Hasso Plattner Institute have come up with a process that may make teleportation a reality — at least in some respects. Their 'Scotty' device utilizes destructive scanning, encryption, and 3D printing to destroy the original object so that only the received, new object exists in that form, pretty much 'teleporting' the object from point A to point B. Scotty is based on an off-the-shelf 3D printer modified with a 3-axis milling machine, camera, and microcontroller for encryption, using Raspberry Pi and Arduino technologies." This sounds like an interesting idea, but mostly as an art project illustrating the dangers of DRM. Can you think of an instance where you would actually want the capabilities this machine claims to offer?
Biotech

New Advance Confines GMOs To the Lab Instead of Living In the Wild 130

BarbaraHudson (3785311) writes In Jurassic Park, scientists tweak dinosaur DNA so that the dinosaurs were lysine-deficient in order to keep them from spreading in the wild. Scientists have taken this one step further as a way to keep genetically modified E. coli from surviving outside the lab. In modifying the bacteria's DNA to thwart escape, two teams altered the genetic code to require amino acids not found in nature. One team modified the genes that coded for proteins crucial to cell functions so that that produced proteins required the presence of the synthetic amino acid in the protein itself. The other team focused on 22 genes deemed essential to a bacterial cell's functions and tied the genes' expression to the presence of synthetic amino acids. For the bacteria to survive, these synthetic amino acids had to be present in the medium on which the bacteria fed. In both cases, the number of escapees was so small as to be undetectable."

they are trapped in this figurative cage we call modern day living.

taking heroin is merely the temporary relief form the typical pains of existence we all experience, to be replaced with a far far worse and much greater pain of addiction

whatever problems you had in life before heroin, are now 100x worse after

You should stop dictating what choices other people make

i'm an empty voice on the internet, i have no power

meanwhile, a drug that rewires your basic reward pathways dictates to you with a freedom destroying, happiness destroying power many times greater than the most fascist authoritarian government of hate you can imagine

wake up from your poorly rationalized denial, or grow some true wisdom about what something like heroin really means to freedom and happiness

It's like having the worst girlfriend ever, who you are madly in love with but who treats you like shit, makes you sell your car and house and furniture and even your high school yearbook that your crush from 10th grade signed and told you that you were cute. She's told you to stop talking to anyone you've ever cared about, they don't want to talk to you while you're still dating her anyways. You sell your clothes so she can go out and buy new ones. You eat ramen every meal so she ca eat at the best restaurant in town. In the morning you think about her and in the evening you think about her and when you go to take a crap but you can't because you're constipated you're reminded of her. You wake up and if she's not in bed with you you get the chills, your eyes water, you have diarrhea, you sneeze, your muscles ache, you have anxiety, you have depression, you don't want to eat because food isn't appealing even though your stomach is rumbling, you don't particularly want to drink but you're dehydrated so you force yourself to drink some water, and during all this your skin is crawling as if it was dirty covered in goose-bumps from who knows where and you wish you were still asleep so you could at least pretend she was still in the bed with you. But you're awake now. So you get out of bed, and you go find her. Maybe today you won't have to do something that compromises your morals to find out where she's gone, but really you don't even care, as long as there is a way. You walk an hour and forty five minutes to get on the bus. You travel for another 45 minutes on public transportation. You get off at the train station in the bad part of town. All the while you have to shit so bad but you know once you find her that will be solved. You're hungry but dont want to eat, once you find her you can eat. You feel dirty and sad and anxious but once you find her she'll bathe you and make you happy and calm. But right now your walking through the ghetto. You walk another 20 minutes. Maybe it's cold and raining, if so you are so so so cold. Maybe it's hotter than hell and that just makes you feel dirtier. You find a guy that knows where she is. He says he'll go get her and bring her to you. And the cops pass you as you're talking to him and they have to know what's up. What's someone like you doing in this part of town? So the 10 minute wait for her to come back to you accompanied by the guy who could give two shits about you as long as you bring him money seems like an eternity. Maybe he'll run off with her and your money. Maybe she wont be looking so hot today, maybe she won't be herself. Maybe he'll come back with a woman you don't know and don't want to meet but now your money is gone and you're broke and sick and a good few hours away before you can get some more money and the world might as well be over in your opinion. But your girlfriend comes back, he brings her, and she gives you a kiss on the cheek. Then you go home, to your mattress and your overdue rent and the lack of food and the piled up bills and the same clothes you've been wearing for three days and your parents that have called but you never answer and your friends that invite you out but you never go, but you're home and she's there with you. Eventually you go to bed. But she's never there the next morning, and you know she won't be, and you wish someone invented a way to pause time, or go back in time, to that first time you met her, the first couple months when you guys hung out, before she made you sell everything to be with her, but you can't and you're fucked. And you know it.

in fact, their capacity for happiness has been permanently degraded, even after they kick the habit. whatever temporary pain they had has been replaced by a permanent reduction in range of choice. for now their very brain chemistry tells them to feed something that in no way contributes to their happiness or freedom. it is a monkey on their back
