French Cleat Wall System and Lots of Boxes
Published on 14 Aug 2015
Subscribe for weekly projects! French cleats are a really great organization system and in this video I show how I added them to my shop to organize tools, nails, screws and my shop vac. I got to use my box joint jig as well to make 43 boxes.

A new anti-censorship tool – Slitheen
The Register‘s Thomas Claburn on a new tool being developed in Canada to aid internet users in countries with hard censorship access material their governments don’t want them to see:
Computer boffins in Canada are working on anti-censorship software called Slitheen that disguises disallowed web content as government-sanctioned pablum. They intend for it to be used in countries where network connections get scrutinized for forbidden thought.
Slitheen – named after Doctor Who aliens capable of mimicking humans to avoid detection – could thus make reading the Universal Declaration of Human Rights look like a lengthy refresher course in North Korean juche ideology or a politically acceptable celebration of cats.
In a presentation last October, Cecylia Bocovich, a University of Waterloo PhD student developing the technology in conjunction with computer science professor Ian Goldberg, said that governments in countries such as China, Iran, and Pakistan have used a variety of techniques to censor internet access, including filtering by IP address, filtering by hostname, protocol-specific throttling, URL keyword filtering, active probing, and application layer deep packet inspection.
In an email to The Register, Goldberg said the software is based on the concept of decoy routing.
“The basic idea behind decoy routing is that the (censored) user’s computer makes an Internet connection to some non-censored (‘overt’) site, such as a site with cute cat videos,” said Goldberg. “However, it embeds a hidden cryptographic tag in its connection, which only a particular Internet router somewhere on the path between the user and the cute cat site can see. That router, seeing the tag, then redirects the traffic to a censored (‘covert’) site, say Wikipedia.”
As Bocovich and Goldberg explain in a paper [PDF] they co-authored, these tags make the web session’s master TLS secret available to a cooperating ISP. This allows the ISP to conduct what amounts to a friendly man-in-the-middle attack by having a network relay it controls open a proxy connection to the censored website.

Just how many calories are you burning during your exercise program?
At The Register, Alistair Dabbs gets around to talking about the next flying car fantasy after first getting his knob squeezed (it’s not what you think) and then trying to do a bit of measurement:
A short while ago, at the end of another 45 minutes of relentless, sweaty knob-tweaking, one of my fellow gym members asked how many calories she could expect to burn at each class. Aha, I like a challenge, and so I decided to use my access to various wearable tech devices in order to find an answer to this question.
Well, I suppose it was a bright idea: the difficult bit was in implementing it.
Bound up by a host of bands and straps, I looked like a cross between a Running Man baddie and a punk reject hanging around Vivienne Westwood’s shop on the King’s Road in 1976. Yet I am tech gladiator incarnate, I told myself. I am Ali-Stor of Bromlar, son of Al-An, defiler of words, wearer of strap-ons, tweaker of knobs!
Maybe the developers of these fitness trackers thought it would be a good idea too. As it turns out, their implementation leaves a little to be desired. Every device measured and calculated my physical effort in a different way, producing wildly different results.
One heart-and-respiration monitor strapped across my chest reckoned I had burnt around 800 calories during the spin class. Another tracker reported a more modest 500 for the same session, with others suggesting various figures in between.
Best of all was my trusty Fitbit, which told me I’d been sitting down and doing nothing for those 45 minutes. No problem, I can simply use the app to log this period in my exercise record as a spin class and let its online database calculate a typical burn for the period.
172 calories.
Oh thanks a bunch, Fitbit. That’s the same as for a 20-minute stroll between my house and the local train station. Next time I consider attending a spin class, maybe I’ll go full-on and nip out to the newsagent instead. It’ll use up more calories and my tender knob can be left unsqueezed.

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
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
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
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.
