Massive Lincoln Archive Goes Live On 150th Anniversary of His Assassination

Lucas123 writes The Lincoln Project, a joint digitization project sponsored by The University of Illinois and the Abraham Lincoln Association, has been identifying transcribing, annotating, and imaging all documents written by or to Abraham Lincoln during his lifetime. Those 100,000 or so documents are now online for the public to view. The documents cover three eras: Lincoln’s time practicing law from 1836 to 1861; his personal life from birth in February, 1809 through March 3, 1861; and his time as president. The archive contains images of some of the most historically significant documents penned by Lincoln, such as one of the five original copies of the Gettysburg Address. It also contains more personal moments, such as a letter he wrote before he became president to an 11-year-old girl responding to her request that he grow a beard to hide his skinny face.

What Knives You Can Carry Where In The United States

What Knives You Can Carry Where In The United States

Knives! Either pointy and scary or practical and useful, depending on who you ask. And that’s reflected in our bizarre hodgepodge of unclearly written knife laws. Let’s make them easy to understand.

Above: Alan Ladd plays a heavily fictionalized Jim Bowie in The Iron Mistress.

But Aren’t Knives Weapons?

A knife is a tool. As evolved apes with opposable thumbs, we’re pretty good at grabbing stuff, pretty good at pushing stuff and even pretty good at twisting or pulling stuff. The thing we aren’t really good at is cutting stuff. At least not without putting it in our mouthes, which leads to all sorts of other problems. A knife gives you the ability to cut stuff and carrying one with you gives you that ability in a package that’s accessible almost instantly and with a single hand. Carrying one is just an essential part of being a capable human.

But, yes anything can be a weapon. Here’s instructions on how to fold a newspaper into a weapon. A ballpoint pen can make a fairly effective impact weapon. But in the hierarchy of stuff you’d grab to fight someone, knives aren’t really high up there. Not if you know what you’re doing. The trouble is that, while they are capable of inflicting fatal injury, they aren’t capable of stopping someone quickly; the fatality tends to come later. That’s a bad combination for any weapon, potentially exposing you to much liability and doing so without saving your own butt.

And, there’s the trouble with demonizing or attempting to control an object that’s hugely commonplace. It might sound sensible to say "No big knives, they’re dangerous." But, go into any kitchen in America and you’ll find knives with blades of six inches or longer. Are those weapons? Like most of the stuff in your house, they could be. But you also need them in order to eat. But also yeah, it’s probably a bad idea to bring that kitchen knife to a public place and wave it around.

Is that kitchen knife more dangerous than something with double edges that’s painted black? Not really, but it’s arguable that the intent changes between different designs of knives. And intent seems to be a huge part of how knife laws are enforced. If it looks scary, cops and courts maybe predisposed to charge you with stuff for carrying it. And even if that scary looking knife is strictly legal, carrying it may expose you to other "deadly weapon" clauses too.

Knife Law Lingo

To understand all this mumbo jumbo, you’ve got to learn what a few words and phrases mean.

Carry Law: A carry law dictates what you’re allowed to have with you, outside of your home.

Ownership Law: These forbid outright the ownership of something; you can’t even have it at home, just for looking at.

Fixed-blade: a knife without a folding mechanism. Your kitchen knives are fixed-blades.

Folding knife: a knife where the blade folds into its handle.

Switchblade: Oh boy, this is where things start to get confusing. Any body that attempts to legislate switch blades has created their own definition of them. And, knife makers have complicated things by creating products designed to barely skirt the law, as it’s expressly written. The 1958 Federal Switchblade Act (the only federal knife law) defines them by saying:

"The term ‘switchblade knife’ means any knife having a blade which opens automatically – (1) by hand pressure applied to a button or other device in the handle of the knife, or (2) by operation of inertia, gravity, or both."

Assisted-Opening Knife: A folding knife which requires you to exert force on the blade in order for it to open, but which ‘assists’ that opening with a spring or mechanism once you have applied force to the blade. These were specifically exempted from the Switchblade Act in 2009.

Gravity Knife: A folding knife where the blade can "fall" open due to the force of gravity. Largely something that opens up interpretation by cops.

Bowie Knife: A large fixed-blade knife. Jim Bowie made his own design famous and that was specifically designed for fighting, but the term has come to mean any large knife.

Stiletto: A very thin knife that’s designed to stab.

Dagger: A knife with sharpened edges on both sides.

Mall Ninja: Someone who thinks scary-looking knives make him tough.

Places You Can Never Carry A Knife

Schools, courts, planes, most federal buildings and similar institutions of state or local government. You aren’t supposed to take a knife onto a military installation unless you’re a member of the Armed Services.

That last thing is actually a regulation I’ve violated many times, going to school on a military base and working as a civilian contractor (handyman) across several. See what I mean about confusing?

Knives You Can Take Anywhere Else

If you simply want a knife you can carry anywhere, then look for something that appears utilitarian and harmless in nature — a Swiss Army knife, utility knife or a multi-tool that includes a blade — and stick to blades of 2.5 inches or less.

For some reason, people find knives that lock open to be scarier than knives that don’t. This silly because that locking mechanism is a safety mechanism, preventing the blade from being able to close on your hand, but also somewhat understandable as most non-locking blades appear more harmless. Again, think of the prototypical Swiss Army knife.

But remember, knife laws are subject to the interpretation of courts and the police. Brandish even a little Swiss Army knife in a manner that may be construed as threatening and the police may decide to use it as an excuse to murder you. Exactly that just happened a few blocks from my house.

What’s Illegal By State Or City (If Significantly Different)

Alabama: Concealed "Bowie" knives (i.e large fixed blades, even kitchen knives), machetes and knives that look like guns. Totally cool to wear any of those on your hip though.

Alaska: Gravity knives and switchblades. And you’re supposed to tell a cop you’re carrying a knife if he stops you.

Arizona: Anything goes. Tell a cop if you’re carrying one.

Arkansas: Please, carry any sort of knife you’d like.

California: No dirks, daggers, stilettos or ballistic knives. No undetectable (ie non-ferrous or hidden in a cane) knives. You’re supposed to carry big knives unconcealed.

Los Angeles: Don’t carry knives in plain view. Exposed pocket clips are supposedly fine.

Colorado: Don’t conceal anything over 3.5 inches. No ballistic knives.

Connecticut: No automatics or stilettos over 1.5 inches. You can’t carry anything over 4 inches.

Delaware: The only knives you can conceal are pocket knives of 3 inches or less.

Florida: If you’re going to conceal it, make it 4 inches or less.

Georgia: If it’s over 5 inches, you need a weapons permit if you want to conceal it.

Hawaii: No balisongs or switchblades. Don’t conceal anything that looks dangerous. Real men fight with their fists anyways.

Idaho: Knives are cool here!

Illinois: No switchblades, throwing knives or ballistic knives.

Chicago: Keep it under 2.5 inches.

Indiana: No ninja stars or pizzas at gay weddings.

Iowa: Pretty much anything goes, but you’re not supposed to conceal anything over 5 inches or a dagger or switchblade or can knife.

Kentucky: Ain’t no knife laws here. Except you’re ain’t supposed to conceal anything scary lookin’

Louisiana: No switchblades.

Maine: Illegal to carry daggers, stilettos or "knives designed for harming others."

Maryland: You can’t conceal a throwing star, dirk, switchblade, gravity knife or bowie.

Massachusetts: The few survivors of the last winter encouraged not to carry switchblades, dirks, stilettos, ballistic knives or ones with knuckle guards as they forage for what meager sustenance remains.

Michigan: Anything goes. Don’t conceal stilettos though.

Minnesota: Anything goes except for switchblades, don’t you know.

Mississippi: You can’t own anything scary looking if you’re a minor or a convicted felon. And no one’s supposed to conceal that scary stuff either.

Missourah: No switchblades.

Montana: Don’t conceal anything over 4 inches.

Nebraska: It’s illegal for a felon to own a knife, which must make cooking interesting. Anyone else can own and carry whatever they want.

Nevada: No belt buckle knives, which are apparently a thing. Don’t try and conceal anything scary.

New Hampshire: Don’t tread on me.

New Jersey: Tony and Vinny can own and carry whatever they want except a switchblade.

New Mexico: No switchblades or butterfly knives.

New York: You can’t own a knife unless you’re a US Citizen. A law currently being violated at every restaurant in the state. And no one’s supposed to have anything scary like a switchblade, throwing star or sword.

New York City: No gravity knives. The cops will make this mean anything if they want to. No knives over 4 inches.

North Carolina: Nothing that shoots its blades. Don’t conceal carry a butcher knife, a bowie knife or anything scary.

North Dakota: No concealing your machete, switchblade or anything else that’s over 5 inches.

Ohio: Anything goes, just don’t be a child playing with a toy gun in a park.

Oklahoma: You can’t carry anything scary, concealed or open.

Oregon: Believes it violates your 2nd amendment rights to tell you what knives you can have or carry.

Pennsylvania: It’s illegal to own a dagger, automatic knife or sword cane. You can’t open or conceal anything scary, including hunting knives. I bet a lot of people break that last law pretty constantly.

Rhode Island: Don’t conceal anything over 3 inches. And the usual no scary stuff.

South Carolina: Own and carry anything you want, any way you want.

South Dakota: Not sure there’s actually laws of any kind here, but you’re definitely cool with whatever knife you want.

Tennessee: You can’t carry anything over 4 inches.

Texas: No gravity knives.

Utah: Anything goes unless you’ve been convicted of a variety of loose criminal charges including delinquency, then no knives for you.

Vermont: No switchblades, if they’re over 3 inches.

Netflix Algorithm Tells You When Your Best Employee Is About To Leave You

An anonymous reader writes "Former Netflix data scientist Mohammad Sabah has used the basis of the video-streaming company’s movie-recommendation engine to create a new system to predict when valuable employees are likely to leave your company for pastures new. The new application ‘Workday Talent Insights’ uses the basis of the engine to correlate diverse factors such as interval between promotions and current length of tenure with equivalent job opportunities at employment websites, in order to gauge ‘corporate restlessness’, and provide options for employers who identify potential leavers."

Ask Slashdot: How To Introduce a 7-Year-Old To Programming?

THE_WELL_HUNG_OYSTER writes I’m a professional programmer and have been programming since I was a small boy. I want to introduce this to my 7-year-son but know nothing about teaching this to children. Since he enjoys Roblox and Minecraft very much, and knows how to use computers already, I suspect teaching him to write his own small games would be a good starting point. I’m aware of lists like this one, but it’s quite overwhelming. There are so many choices that I am overwhelmed where to start. Anyone in the Slashdot in the community have recent hands-on experience with such tools/systems that he/she would recommend?

How To Tie The Only Five Knots You’ll Ever Need

How To Tie The Only Five Knots You'll Ever Need

There’s a million different knots for doing a million different things. But, these five are easy-to-learn, easy-to-tie and accomplish 99 percent of the jobs you’ll ever need a rope to do. Anyone can make these, here’s how.

Knot tying has always been one of my poorest skills. I think I actually earned the Velcro merit badge back in Boy Scouts instead. So, when it comes to using them, I need simple, easy, reliable ones that are still capable of performing real work, across a diverse array of tasks. These are the five knots I’ve learned and rely on. They get me through pretty much anything.

Good Knot-Tying Practices

The more knots you tie in a rope, line or string, the more you reduce its strength. And, the right not won’t slide or come undone when you want it to, but may still be easy to reposition, adjust or untie as a result. That’s why learning to use the right knot for the job is so important.

You wouldn’t think that something as simple as tying a knot could be dangerous, but depending on what you end up using it for, a broken line or a slipped knot could hurt or kill someone. Or, your cargo could simply fly off the roof of your car. To avoid that happening, you need to practice; only ever use a knot you’re sure of.

To get the most from your knot tying, you’ll also want to work with clean, dry cordage of an appropriate strength, size and elasticity for the job. If you’re not sure how much a rope can hold, don’t trust your life to it.

When you’re making a knot, it’s important to keep the line from twisting, binding and to try and keep tension even throughout its construction. That’s going to be easiest on a flat surface, as you see here, keeping the knot spread out and flat allows you to observe its form and adjust the lengths of its individual parts as you tinker with it.

Don’t assume you can just watch one of these gifs then rely on that knowledge next time you’re in the outdoors and standing in the home depot parking lot with a pile of lumber. Practice them at home, practice them in the field on non-critical jobs and, only when you’re confident in them, start relying on them instead of that handy Velcro kit.

How To Tie The Only Five Knots You'll Ever Need

Bowline Hitch

Need to rescue someone? Throw them a bow line, which won’t ever slip or tighten. That avoids injury and gives them a secure loop to grab, step in or put their arms through. Bow lines also make great handles, again because the loop will never, ever slip. It’s also incredibly quick and simple to tie, even with cold, wet, shaking hands.

Create a loop by passing the working end of the line over the top of its body. The rabbit comes out of the hole, runs around the back of the tree, then jumps back down. Pull it tight at your desired size for the loop and you’re done. Easy.

Two Half Hitches

Want to tie a rope to something? This is how you do that. Use the two half hitches to tie off a tarp or hammock with a strong, quick, secure connection.

Pass the line behind the tree/pole/limb, loop it up, over the body, then through. Loop it up, over and through again and pull it tight. That’s not going anywhere.

Tautline Hitch

Want to tie a rope off to something, but be able to vary its length? Think tent guy line or similar. This is the easiest way to do that and the knot will hold its place on the line, so long as tension remains on it.

Bring the working end of the line over its body. Pass it behind, on the loop side. Cross that over the loop then come down over the body. Wrap it over the body and pull it through. Tighten it up and it’ll hold whatever tension you set.

As a variation, you can tie-on a separate line using the same knot, thereby adding one or more lengths of rope to another in a way that they’ll hold their place under tension, but allow you to slide that position up and down the main line.

How To Tie The Only Five Knots You'll Ever Need

Figure Eight

A traditional square or overhand knot binds so tightly under tension that you often have to resort to cutting the rope rather than untying the knot. The figure eight allows you to easily tie a rope onto a carabiner or similar securely, but easily untie it even after applying huge tension. This one’s used on sailboats and in climbing as a result, but you can use it anywhere you’d like to attach something to a rope.

There’s two versions. In the first (above), you’re tying the rope to something with a closed loop that the rope must pass through. It looks a little complicated as you’re passing the rope back through itself after going through the tie-off point, but the trick is just to follow the figure eight back around. Difficult to photograph, but easy to do once you figure it out once.

How To Tie The Only Five Knots You'll Ever Need

The second is easier and assumes you’re attaching to something with a clip, like a carabiner. You could tie this with your eyes closed, which is sorta the idea: it’s dead simple and impossible to forget. And, it retains 85 percent of the rope’s strength when tied.

How To Tie The Only Five Knots You'll Ever Need

Trucker’s Hitch

Ever wondered how people tie stuff tightly to the top of their cars? This one will allow you to drive home with a mattress on your roof, without it blowing off. It does that by giving you simple mechanical advantage that enables you pull the rope tight, then lets you tie it off quickly and easily while it’s still tight. Once you’ve figured this one out, a hank of paracord kept in your trunk will allow you to haul pretty much anything. It can also be used to tie something down tightly virtually anywhere. Need to compress a foam roll and attach it to your backpack? This is how. You’re welcome.

Create a figure-eight loop in the line with plenty of length left to work with. Pass the working end around a fixed tie-off point, through that loop you just made and pull it as tight as you need. Then, you’re basically just creating a two half hitch to tie it off.

What are your favorite knots?
