    October 20, by Moove In Self Storage You want your belongings to be safe and secure at all times in storage. You look for security cameras, check to see if the property is well lit, confirm there is a fence surrounding the self storage units with an access gate and that there is a property manager on-site regularly — all good things!

    One step many people overlook is choosing the best lock for your storage unit. Knowing the facility is secure is very important, but having the right lock is another protection against theft; so it should not be taken lightly. You may think you can just bring in a lock from home to save some money. However, that would be a big mistake. Keep in mind that if something bad were to happen, that lock is what will keep them out — or let them in… if you choose poorly.

    There are many different types and styles of locks that you can purchase. We want to help you choose wisely. Here are some common options for best storage unit locks along with pros and cons: 3rd Best Lock for Storage Unit: Keyless Lock The name means just that, no key exists. Instead of using a key to open and close the lock, you will either punch in a series of numbers or dial a combination.

    These locks were originally developed for cars with remote entry systems, but have been modified for residential applications like the front door at your house, the lock for your gym locker or a bicycle chain lock. The advantages of this lock are minimal — no key required and you can give others access at your discretion. Ok, so there is no key to lose, but so what? The disadvantages are much greater; an intruder can guess the code or hack into the lock; you can forget the code.

    Many are powered through electricity and incorporated into a security system, which may not function when the power goes out.

    Also, a keyless lock such as a standard combination lock is not recommended for outdoor use. It can be easily cut open with bolt cutters or a hack saw and done so very quickly. You typically see these on outdoor sheds, lockers and for small items like your luggage and the gas meter at your home.

    Some of the advantages of this lock type can actually be viewed as negatives when you consider how they would be used at a self storage facility. They can be re-keyed very easily if you lose the key, without having to remove the lock. That may be great to get into your gym locker to retrieve your favorite shoes, but that also means someone with a little knowledge can get into the lock without your permission.

    Again, the disadvantages outweigh the positives. Bump keys exist provided it is the same manufacturer of the lock and can provide quick access to open a padlock; just do a quick search online and you will be shocked at how fast a teenager can gain access from this method.

    There are many advantages of choosing a disc lock. To start, they were actually developed specifically for self storage facilities and are recommended across the industry as the go-to lock to use. Hitting one of these locks with a hammer will not break the lock, like it can on keyless locks and padlocks.

    Picking this lock type is also not an easy feat when compared to other lock types. To remove a disc lock without having the key requires a bit of time and tools.

    You actually need to grind it off. Someone who is not authorized to be on the property will quickly move on to an easier target like a padlock or keyless lock because grinding off a disc lock takes a lot of time and makes a lot of noise. These locks are also stainless steel, meaning no rust will form when being outside in the elements year-round. Another benefit to this style is that many insurance companies offer a zero deductible or lower premium if you secure your storage unit with a disc lock.

    So it will cost a little more than a standard padlock. But I think you would agree it is well worth the price to keep your belongings safe. Disc Lock Sizes Besides the type of lock you choose, you also need to consider the size of the lock. They are measured across the width of the lock. One thing to keep in mind: the smaller the lock, the easier for someone to remove it. You want to choose the largest lock you can for the latch to add another layer of protection.

    Lastly, if you have a storage unit with outdoor access, make sure you choose a lock designed for the outdoors. The direct sunlight, rain, snow and extreme temperatures from outside can affect the durability of the lock. Stainless steel is the recommended material for an outdoor lock because of its durability.

    If you have an indoor access unit, choose either an outdoor or indoor use lock. We want your stuff to be safe and secure just like you do.

    The lock you choose is the best defense against someone entering your storage unit without your permission. We offer disc locks for sale in our rental office! You can easily get the best lock without having to shop around. In Conclusion It may seem like a simple step; just buy a lock and you are good to go. However, all locks are not created equal and you want to be sure to purchase the correct size and style. If you have any questions about locks, please contact any of our property managers or fill out our contact form.

    PFAS: The Organofluorines Your Biochemist Warned You About

    But are there new lessons in our age of cheap and open source automation? Or does it simply re-confirm that age-old open source wisdom — that given enough eyeballs, all bugs are shallow. Our story begins with an engineer at SparkFun whose wife gave him an unusual Christmas gift — a locked safe with no combination. Step 2 Deploy robot army.

    But with three two-digit numbers, there were a million possible combinations — and even trying one every 10 seconds would still have taken almost four months. Fortunately, this particular brand of safe had a built-in margin of error. If you already have the first two digits, you could simply spin the dial. Safe manufacturers try to make this harder by stopping the spinning with 12 indents — but that actually made things easier.

    That last ident — for the final number in the combination — is apparently. That means it can be identified by the dial-turning robot through a series of careful automated measurements, leaving just 33 x 33 possible combinations — that is, In a triumphant moment, the device beeped, displayed the combination — and ended its search drawing an enthusiastic round of applause from the audience. I want to point out this issue so that you can make this more secure.

    New combination locks were promptly installed — which Feynman took as just another challenge. Upgrading a Tradition Safe-cracking continues to be a popular topic among geeks of today. Olin College of Engineering in Needham, Massachusetts. And several years ago two MIT students even built a laptop-controlled robot that could open high-security safes. One geek who was particularly interested in the safety of real-world locks was Matt Blaze, the creator of the original Cryptographic Filesystem CFS for Linux.

    Cryptographer Gus Simmons born in once gave a dual-key Abloy cylinder to Blaze, which became one of his most valued possessions. Few weaknesses in physical security admit the kinds of catastrophic failures common in computers and networks, in which a low-risk, low-cost attack can yield a high-value and easily replicated benefit. Relatively accurate estimates of the time and other resources required for various kinds of attacks make it possible to tightly optimize effective physical security systems and to coordinate complementary security mechanisms.

    Some suggest that the best stance is a critical eye to our illusions of security. Not your computer, not your cell phone, and definitely not whatever it is you keep in your safe at home.

    Which Lock is the Best Lock to Use to Secure My Storage Unit?

    There are many advantages of choosing a disc lock. To start, they were actually developed specifically for self storage facilities and are recommended across the industry as the go-to lock to use. Hitting one of these locks with a hammer will not break the lock, like it can on keyless locks and padlocks. Picking this lock type is also not an easy feat when compared to other lock types. Rust is great for rewriting performance-sensitive parts of your application.

    The 1. That makes it safe to recommend Rust for even the most demanding and robust applications! Getting started with Rust There are many tutorials covering Rust in general, as well as specific aspects of the language. For example, the Rust blog has great articles on various facets of developing Rust applications.

    He explains the main concepts and motivations behind Rust nicely, and the talk serves as the perfect appetizer, starting you on your journey: Talks and tutorials are no substitute for writing code, right? The Rust Book was conceived to help you get started — from installation to that first Hello World to providing an in-depth reference for all the core language features. Rust By Example offers invaluable live-editable, in-browser examples with all of the articles.

    There is also a Rust Playpen for the exact same purpose. Not that downloading and installing Rust is much trouble, anyway. The downloads contain all the tools you need to get started like rustc, the compiler, or cargo the package managerand are available pre-built for all platforms Windows, Linux, and OSX.

    What is it then, that makes Rust so unique, so different? It is also invaluable in keeping the language runtime minimal and the compiler output lean and performant. The owner of said resource is responsible for using, possibly lending out the resource to other usersand finally cleaning it up.

    All this happens automatically, with the help of scopes and bindings: bindings either own or borrow values, and last till the end of their scope. As bindings go out of scope, they either give their borrowed resource back, or in case they were the owner, dispose of the resource. Zero-cost abstractions Since the correct operation of a program is asserted at compilation time, code that compiles can generally be considered safe with regard to most common types of memory and concurrency errors such as use-after-free bugs or data races.

    This is possible because Rust complains at compilation time if the programmer attempts to do something that violates the principles above, which in turn helps keep the language runtime minimal. In the case of memory allocations, there is no need for runtime garbage collection, either.

    The principles of ownership and the borrow checker are essential for understanding Rust, and are key to other powerful aspects of the language, like its handling of concurrency and parallelism.

    Two birds, one language construct Shared mutable state is the root of all evil. Most languages attempt to deal with this problem through the mutable part, but Rust deals with it by solving the shared part. It might seem surprising, but the ownership system coupled with a few handy traits also provides powerful tools for threading, synchronization, and concurrent data access. When you try some of the built-in concurrency primitives and start digging deeper into the language, it may come as a surprise that those primitives are provided by the standard library, rather than being part of p5js star language core itself.

    Performance or expressiveness? Choose both! By moving the various checks out of the runtime and getting rid of garbage collection, the resulting code mimics the performance characteristics of other low-level languages, while the language itself remains much more expressive.

    When Open Source Hacking Meets Safe-Cracking

    The seemingly high level constructs strings, collections, higher order functions, etc. This may seem a bit anti-climactic, but there are only so many ways to write a Hello World in Rust. Bear with us while we share a slightly more complex example — and another timeless classic. Fizzbuzz is an algorithm in which we count upwards for all eternity, replacing some of the numbers with fizz for numbers evenly divisible by 3buzz for numbers divisible by 5or fizzbuzz divisible by both 3 and 5.

    The most obvious difference might be that we are using pattern matchinginstead of traditional if statements. Traditional for loops are considered error-prone and are replaced with the safer and more flexible iterable concept. This is not the place to go deep on how pattern matching or destructuring work, or what tuples are.
