Top 5 Myths about Guns That Hollywood Taught Us

Forget what you see in the latest action movies or even video games, these gun myths shouldn’t be believed. We see it everywhere; James Bond, Westerns, Call of Duty, Fast and Furious, Terminator, Black Hawk Down, The Expendables, Goldeneye, Battlefield, Taken, Die Hard, Bon Cop Bad Cop, The Matrix, and so on – They’re all Bullshit, but we fall for them thanks to Hollywood. Here’s looking at you Arnold Schwarzenegger and Sylvester Stallone.

Can Bullets shoot through cars? Will gas canisters explode if you shoot them? Am I safe from bullets underwater? Those questions and more will be answered in this edition of Watchmojo’s Top 5 Myths.

Tank Chats #7 British Mark II

Filed under: Britain, History, Military, Technology — Tags: , — Nicholas @ 02:00

Published on 2 Jul 2015

The seventh in a series of short films about some of the vehicles in our collection presented by The Tank Museum’s historian David Fletcher MBE.

Only fifty tanks each of Marks II and III were produced. They were unarmoured, in the sense that the steel from which they were built was not heat treated to make it bullet proof. The reason being that these tanks were only intended for use as training machines.

The chief external differences from Mark I lay in the tail wheels, which were not used on Marks II and III and later heavy tanks, the narrower driver’s cab and the ‘trapezoid’ hatch cover on the roof.

How do spacesuits work? | James May Q&A | Head Squeeze

Filed under: History, Space, Technology — Tags: , — Nicholas @ 02:00

Published on 8 Nov 2013

You’ve seen the videos of those astronauts on the International Space Station getting suited and booted in a spacesuit before a spacewalk, but how exactly does the space suit work?

A spacesuit has to protect you from the glaring radiation from the sun as well as keeping you warm from the extreme cold of outer space. As well as that is has to make sure you have enough oxygen and enough movement so you can actually do your job.

It also has to be pressurised to about 4.7PSI. Otherwise the empty vacuum of outer space will make your organs increase to twice their normal size and you will meet a very unpleasant untimely death.

Don’t fancy building your own spacesuit, why not build an elevator into space? http://www.youtube.com/watch?v=annVRxRjj4c&feature=c4-overview-vl&list=PLMrtJn-MOYmeNkbYzXsEluioufGDxuqtO

Microsoft buries the (security) lede with this month’s patch

Filed under: Technology — Tags: , , , — Nicholas @ 05:00

In The Register, Shaun Nichols discusses the way Microsoft has effectively hidden the extent and severity of security changes in this month’s Windows 10 patch:

Microsoft today buried among minor bug fixes patches for critical security flaws that can be exploited by attackers to hijack vulnerable computers.

In a massive shakeup of its monthly Patch Tuesday updates, the Windows giant has done away with its easy-to-understand lists of security fixes published on TechNet – and instead scattered details of changes across a new portal: Microsoft’s Security Update Guide.

Billed by Redmond as “the authoritative source of information on our security updates,” the portal merely obfuscates discovered vulnerabilities and the fixes available for them. Rather than neatly split patches into bulletins as in previous months, Microsoft has dumped the lot into an unwieldy, buggy and confusing table that links out to a sprawl of advisories and patch installation instructions.

Punters and sysadmins unable to handle the overload of info are left with a fact-light summary of April’s patches – or a single bullet point buried at the end of a list of tweaks to, for instance, Windows 10.

Now, ordinary folk are probably happy with installing these changes as soon as possible, silently and automatically, without worrying about the nitty-gritty details of the fixed flaws. However, IT pros, and anyone else curious or who wants to test patches before deploying them, will have to fish through the portal’s table for details of individual updates.

[…]

Crucially, none of these programming blunders are mentioned in the PR-friendly summary put out today by Microsoft – a multibillion-dollar corporation that appears to care more about its image as a secure software vendor than coming clean on where its well-paid engineers cocked up. The summary lists “security updates” for “Microsoft Windows,” “Microsoft Office,” and “Internet Explorer” without version numbers or details.

Vantablack – the discovery that fits everybody’s preferred story line

Filed under: Technology — Tags: — Nicholas @ 03:00

At Samizdata, Brian Micklethwait attempts to look at the newly announced blackest black ever, Vantablack:

In the event that you have somehow managed to miss this story, you can get some idea of how very black Vantablack is by pondering this image, of a mask, together with the same mask covered in the liquid version of Vantablack. The Vantablacked version of the mask might as well be a flat piece of cardboard for all the 3-D shape detail you are able to discern by looking at it. You’d need to be a bat to make sense of it:

That image is to be found at a British Museum posting entitled Vantablack is the new black. I googled that gag, confident that someone would already have used it as a heading, and so it proved.

[…]

If you are the kind that blames capitalism for causing poverty (instead of praising capitalism for getting rid of poverty, the way I do and you should) then perhaps you will say that Vantablack proves how frivolous capitalism is, making black even blacker when there is still so much misery in the world. If you believe that universities should get more government money (Vantablack emerged from the University of Surrey), well then, you’ll say that Vantablack proves that universities should get more government money. If you are an anti-Trumpist or an anti-Brexiteer, you will regard the Vantablack story as proof that we really are living in uniquely dark times. If you are the kind of commenter here whose reaction to any new-tech fuss we report is that it is a fuss about nothing, or perhaps if you are the sort who wants to make fun of such grumpiness, you will perhaps even now be contriving a comment that includes the words: nothing to see here.

The Internet-of-Things wants to invade your kitchen

Filed under: Business, Technology — Tags: , — Nicholas @ 04:00

Megan McArdle on the good and bad (mostly bad, IMO) of adding extra layers of technological sophistication to your kitchen appliances. If someone hasn’t already offered a hand-blender, can-opener, or soup tureen with Wi-Fi and/or Bluetooth built-in, just wait a bit … it’s bound to happen.

I don’t think of myself as having Luddite tendencies, but I confess that when I see refrigerators with screens set into their doors, my first thought is: “Why?”

No, don’t tell me that you can stream music or look inside the refrigerator. I already have technology for that — respectively, my Amazon Echo and this app called “opening the door.” Neither costs the thousands of extra dollars I would have to pay to get my hands on a Samsung Family Hub Refrigerator. And if my music streamer breaks, I can replace it without calling an appliance repair company and spending a fortune on parts.

I have similar sensations about many of the technologies on offer in today’s appliances. Every major appliance manufacturer seems to be looking for a way to stick wi-fi into their products, for example. And I confess, I have occasionally fantasized about starting a pie cooking in my oven, sauntering to the other side of my 5,400-square-foot home for a dip in the pool, and being able to use my phone to turn down the heat on the pie after 10 minutes. Alas, in the trim 1,700-square-foot rowhouse I actually live in, I am never far enough from my kitchen to actually justify resorting to my smartphone rather than my feet.

We are at a curious moment in cooking technology. The last decade or so has probably introduced more technology potential into the kitchen than any previous decade except the 1930s. Sous vide, electric pressure cookers, fuzzy logic rice machines, induction cooktops, food processors that also cook, wi-fi controls, web connections … these things are now common enough for ordinary cooking enthusiasts to have at least heard of them, if not tried them. It is an era of enormous potential. And yet, that potential is frequently not realized, because we can’t actually figure out what to do with all our new toys.

Don’t get me wrong: I’m not saying that all of this new technology is useless. Far from it! I am an enthusiast for many of them. And yet, almost all these whiz-bang technologies fall prey, to some extent, to one of two problems. Either they are not actually very useful, or they are so spectacularly revolutionary that the average home cook can’t figure out what to do with them.

And this doesn’t even dip in to the awesomely terrible security issues of so many Internet-of-Things devices, creating new, wide vistas for Ransomware scumbags…

The (inevitable) failure of the “Revolution in Military Affairs”

Filed under: Military, Technology, USA — Tags: , , , , — Nicholas @ 03:00

In an article about security incident response automation, Bruce Schneier provides a useful thumbnail sketch of a US Army attempt to dispel the fog of war in real time:

While this is a laudable goal, there’s a fundamental problem with doing this in the short term. You can only automate what you’re certain about, and there is still an enormous amount of uncertainty in cybersecurity. Automation has its place in incident response, but the focus needs to be on making the people effective, not on replacing them ­ security orchestration, not automation.

This isn’t just a choice of words — it’s a difference in philosophy. The US military went through this in the 1990s. What was called the Revolution in Military Affairs (RMA) was supposed to change how warfare was fought. Satellites, drones and battlefield sensors were supposed to give commanders unprecedented information about what was going on, while networked soldiers and weaponry would enable troops to coordinate to a degree never before possible. In short, the traditional fog of war would be replaced by perfect information, providing certainty instead of uncertainty. They, too, believed certainty would fuel automation and, in many circumstances, allow technology to replace people.

Of course, it didn’t work out that way. The US learned in Afghanistan and Iraq that there are a lot of holes in both its collection and coordination systems. Drones have their place, but they can’t replace ground troops. The advances from the RMA brought with them some enormous advantages, especially against militaries that didn’t have access to the same technologies, but never resulted in certainty. Uncertainty still rules the battlefield, and soldiers on the ground are still the only effective way to control a region of territory.

But along the way, we learned a lot about how the feeling of certainty affects military thinking. Last month, I attended a lecture on the topic by H.R. McMaster. This was before he became President Trump’s national security advisor-designate. Then, he was the director of the Army Capabilities Integration Center. His lecture touched on many topics, but at one point he talked about the failure of the RMA. He confirmed that military strategists mistakenly believed that data would give them certainty. But he took this change in thinking further, outlining the ways this belief in certainty had repercussions in how military strategists thought about modern conflict.

McMaster’s observations are directly relevant to Internet security incident response. We too have been led to believe that data will give us certainty, and we are making the same mistakes that the military did in the 1990s. In a world of uncertainty, there’s a premium on understanding, because commanders need to figure out what’s going on. In a world of certainty, knowing what’s going on becomes a simple matter of data collection.

“You can’t buy my internet data. You can’t buy your internet data. That’s not how this works

Filed under: Government, Liberty, Technology, USA — Tags: , , , — Nicholas @ 04:00

At Techdirt, Mike Masnick bravely attempts to tamp down the hysteria over this week’s vote in Congress to kill broadband privacy protections (which, as he notes, hadn’t yet come into effect anyway):

People are rightfully angry and upset about this. The privacy protections were fairly simple, and would have been helpful in stopping truly egregious behavior by some dominant ISPs who have few competitors, and thus little reason to treat people right. But misleading and misinforming people isn’t helpful either.

[…]

But here’s the real problem: you can’t buy Congress’ internet data. You can’t buy my internet data. You can’t buy your internet data. That’s not how this works. It’s a common misconception. We even saw this in Congress four years ago, where Rep. Louis Gohmert went on a smug but totally ignorant rant, asking why Google won’t sell the government all the data it has on people. As we explained at the time, that’s not how it works*. Advertisers aren’t buying your browsing data, and ISPs and other internet companies aren’t selling your data in a neat little package. It doesn’t help anyone to blatantly misrepresent what’s going on.

When ISPs or online services have your data and “sell” it, it doesn’t mean that you can go to, say, AT&T and offer to buy “all of Louis Gohmert’s browsing history.” Instead, what happens is that these companies collect that data for themselves and then sell targeting. That is, when Gohmert goes to visit his favorite publication, that website will cast out to various marketplaces for bids on what ads to show. Thanks to information tracking, it may throw up some demographic and interest data to the marketplace. So, it may say that it has a page being viewed by a male from Texas, who was recently visiting webpages about boardgames and cow farming (to randomly choose some items). Then, from that marketplace, some advertisers’ computerized algorithms will more or less say “well, I’m selling boardgames about cows in Texas, and therefore, this person’s attention is worth 1/10th of a penny more to me than some other company that’s selling boardgames about moose.” And then the webpage will display the ad about cow boardgames. All this happens in a split second, before the page has fully loaded.

At no point does the ad exchange or any of the advertisers know that this is “Louis Gohmert, Congressional Rep.” Nor do they get any other info. They just know that if they are willing to spend the required amount to get the ad shown via the marketplace bidding mechanism, it will show up in front of someone who is somewhat more likely to be interested in the content.

That’s it.

* Amusingly, Rep. Gohmert voted to repeal the privacy protections, which makes no sense if he actually believed what he was saying in that hearing a few years ago…
