3 things to consider before buying a budget projector
You’ve been looking for the best projector under 300 to buy and you have come to the conclusion that you need to know some important details before making the purchase. You should take into account resolution, lumens, and connectivity. All three of these factors are important because they play a key role in determining the quality of your viewing experience. Resolution Resolution is one of the key factors to consider while buying a projector. The resolution of a projector is the number of pixels it is capable of producing and displaying. For example, a 1080p projector can produce 1080 pixel images. Resolution is the pixel count of an image. The resolution of a projector is always quoted as a number of pixels. As you go higher in resolution, the number of pixels increases, and hence the overall image is sharper and more detailed. If you see a projector with a higher resolution than another, it means that it can display more detailed images, which is a good thing. In general. if you are buying a projector for home theater, you should go for 1080p, as it is the most common resolution nowadays and can be viewed from a reasonable distance, unlike 4k (which is much sharper). 2. Lumens Lumens are the measurement of how much light a projector can emit. It is like the unit of measurement for how bright a projector is. Technically, one lumen is equal to one candela per square meter. It is usually used as a measure of light output for projectors and video displays. It is very important for you to consider the lumens of a projector when you are in the market for a new one. So, how do you determine the lumens of a projector? As a rule of thumb, the brighter the better. You may have noticed the term "brightness" when shopping for projectors or displays. If you are looking for a projector for dorm rooms, You should look for a projector with at least 1500 lumens. This is because it gives you a good mix of brightness and cost. connectivity The connectivity of a projector is what allows you to connect your projector to devices like computers, laptops, smartphones, Blu-ray players, gaming consoles, etc. The connectivity is what allows you to get your content onto the screen. The better the connectivity, the more devices you can connect to the projector. As a rule of thumb, the better the connectivity, the more expensive the projector will be. You'll want to ask yourself what kind of content you'll be projecting, and how you'll be projecting it.

How do you dispose of old hard drives
Go to your local computer store and ask if they’ll take old drives for recycling. Apple Stores will recycle old industries for free, and I believe other stores charge a small fee, but that money goes to charity. Some companies specialize in taking hard drives out of electronics and recycling them responsibly. There are three things you should know about this option. First, hard drives contain a lot of sensitive information that you might not want anyone to see. Even if the data is encrypted (as it should be), there are ways to get around encryption. If your drive has an operating system, it can sometimes be cracked open, and the data read directly from the disk. Second, hard drives don’t last forever. They have a limited lifespan, and they do eventually fail. This can happen soon after being removed from the computer or many years later. Third, you can’t trust the company that might be making the data recovery. Even if they don’t do anything illegal, there is a high probability that they will sell your data to a third party. So be careful to securely dispose of old drives and SSDs data. How to securely dispose of old hard disk drives and SSDs So you’ve decided to get rid of your old hard drive or SSD. Here are some tips for securely disposing of old drives and SSDs and how to do it safely. You use drives or SSDs in your Macs or pc, and hopefully, you also use some hard drives to back up your data. Over time, some drives and data go bad, and others get too small, so you replace them. You may be able to repurpose old hard drives, but in some cases, they’ve lived a good life, and it’s time to consign them to the bit bucket. But you can’t just throw away a hard drive or drop it off at a hard drive recycling center. These drives may contain personal data, Company data, and you need to deal with them carefully to ensure that no one can recover your information. Here’s how. When to upgrade drives You should have a backup of your Mac and of all its data for future use. Ideally, you use a combination of Apple’s Time Machine and Indigo Personal Backup to ensure that all your drive data is backed up securely and redundantly. (Two backups are better than one.) Over time, you acquire more data, especially if you have a growing media library that drives age. That 1 TB drive you bought a few years ago for use no longer holds all your music and movies, so you need to get a larger hard drive. In some cases, you can still use that older drive for use other backups, but as time goes by and you upgrade every few years, you’ll have a collection of hard drives of varying sizes that aren’t really worth keeping. I’m pretty careful about my hard drive data and my backups, and I tend to replace my hard drives every three years or so. Statistics show that the failure rate for hard drives increases substantially around that time, and it’s often around then that I find I need more drive storage anyway. Your usage may vary, but given the low cost of drives today and the need to ensure that you don’t lose data this time, that’s probably a good time to look for replacements. How to erase drives Before going any further, you should securely erase your hard drives. This article tells about the hard drive for you, how to do this with Disk drive Utility, and also how to securely erase free space from a hard drive and SSD from the command line (using the Terminal app) since you can’t securely erase SSDs. It’s worth noting that if you’ve been using File Vault, or encrypted your hard drives with your Mac, then you probably don’t have to worry about erasing them. As long as the passcode required is complex enough that no one can figure it out, then you may feel comfortable with just taking the hard drive recycling center. However, if you are still worried about recycling drives, haven’t encrypted the drives, or if you’re not sure and they don’t work, then you should take them apart. How to disassemble hard drives When you’ve got a bunch of old drives you want to get rid of, it’s time to get out some drive tools and get to work. You’ll need a number of obscure screwdrivers for separate parts of the drive, so it’s best to buy a set of computer tools. I use a tool kit, and I’ve never encountered a screw for which it doesn’t have ahead. Start by unscrewing every screw you can find for the hard drive, especially on the aluminum cover of the disk. Some hard drives have a number of different types of screws, and others use all the same type. You may find that some screws are stuck, and you may need to resort to some other tools to separate parts of the disk drive. (Keep a good pair of pliers and a sturdy flat-head screwdriver handy.) Here’s one drive I took apart where I couldn’t get all the screws for separate parts of the disk drive off the cover, so I had to bend it with pliers: Depending on the size of the hard drives, and their ages, the platters will be a different size. I recently destroyed some 2.5″ drives, and the platters were made of glass. For these hard drives, you can just shatter the platters. Be careful. The hard drive glass can be very sharp, so goggles and gloves are recommended. 3.5″ hard drive platters are made of aluminum, with several coatings of different materials. For these platters, there are a number of ways to ensure that Disk data cannot be recovered. Depending on your tools for the separate disk drive, you could: Steep1: Soak them in acid Steep2: Scratch them all over with a screwdriver Steep3: Sandblast them Steep4: Deface them with a multi-tool (a grinding head) Steep5: Demagnetize them with a very strong magnet Plan ahead It’s best to plan ahead and use full-disk encryption for all your hard drives, so you don’t have to worry about your drive data being accessible when you need to get rid of them. Securely erasing data from the drives is a good idea, and as a last resort, disassembling them and destroying the platters makes a good weekend project.

Top Common Java Interview Questions in 2022 | Optymize
Java at present has a claim as one of the most popular, if not the most popular programming language at present among developers. So, any aspiring developer must have a working knowledge of the language, so to get an accurate judgment in regards to their capability, here are some common java interview questions to assess them. This article will cover not only such java interview questions but also various feature s, history, and other facets of the Java programming language. Introduction to Java and its History and its Milestones Java is a high-level, class-based, object-oriented programming language that was intended to be WORA (Write Once Read Anywhere). It means that it will have as few implementation dependencies as possible, allowing compiled Java code to run anywhere else without recompiling. This is thanks to the fact that Java applications are compiled to bytecode, which can run on JVMs (Java Virtual Machines). This makes the applications independent of the supporting computer’s architecture. Java itself bears a lot of similarity in syntax to older languages like C and C++ in order for familiarity with programmers with previous experience in the latter languages. Outside of that, it also boasts additional features, programming libraries and frameworks that have allowed it to claim a spot as one of the most common programming languages in the world today. Java was initiated in 1991, designed for use in interactive televisions, but the hardware at the time wasn’t advanced enough. As such, when it was released in 1996, its selling point was instead the familiar syntax and the WORA functionality. Other features like network and file access restriction and configurable security made it fairly secure and it has found a willing user base with software developers and browsers for Java applets. There are additional milestones in Java’s history that may often form the base of Java interview questions. These include 1997, where there was an attempt at standardisation, 2006 when the JVMs core code was almost in its entirety released as an open-source software and the dates when older editions were discontinued. These may seem like meaningless trivia, but they find some relevance when dealing with legacy code. Beginner Java Interview Questions The beginner Java interview questions refer to Java interview questions that are meant for the college intern or a beginner, junior level developer. Such Java interview questions are meant to ascertain whether the applicant has a working knowledge of the Java programming language. The applicants that are asked these sets of Java interview questions are likely to have only previous experience with Java in the form of practical classes and projects rather than actual work experience. Depending on how they answer the Java interview questions, additional training may be necessary, so they tend to cover both general as well as slightly advanced topics. 1. Explain about the Basics of Java This is one of the introductory Java interview questions that is asked in nearly every scenario for a newcomer. A lot of the features have been described in the previous section. However, it’s more than just a simple technical knowledge as it is often the source of justification for why they are choosing Java as a programming language of choice. 2. State the differences between Java and a similar programming language like C++ or C This is another one of the Java interviews questions that is expected for any Java newcomer in the field. When answering this question, they should be able to point out major factors such as platform dependencies, features like inheritance, overloading, calling, overriding, etc. Also refer to objectives, applications and language type. 3. Explain about the features and characteristics of Java This is one of the more flexible Java interview questions as many of the features can also be their own interview question. These can include features like abstraction and encapsulation along with the available primitive data types. 4. Define Java Bytecode The bytecode is responsible for Java’s claim to be written once, read anywhere. The Java compiler converts Java programs into bytecode, which is an intermediate between source and machine code and independent of the platform. 5. Define JVM (Java Virtual Machine), JRE (Java Runtime Environment) and JDK (Java Development Kit). Differentiate between them The two Java interview questions above are interrelated as many of the defining features can also be used to differentiate between them. For instance: 1. Java Virtual Machine: An abstract machine that provides the runtime environment. 2. Java Runtime Environment: Physically existing implementation of JVM as a set of software tools for developing Java applications. 3. Java development kit: It is an implementation of ME, SE or EE java platforms, consisting of JRE with development tools. 6. List the Default Data Types in Java This is one of the basic, yet deceptively tricky basic Java Interview Questions. While the eight, primitive data types are simple in terms of definitions and range, they are often reused in different programming languages, so it occasionally becomes a point of confusion among beginners, what data type belongs to which language. The additional questions in this topic can include the steps on how to convert data from one type into another and this overlaps with the topic of features of java. 7. Explain about Garbage Collection This is one of the primary features that is present in Java but it occasionally shows up separately among Java interview questions. As such, it has been presented here specifically as well. 8. Define Java’s JIT Compiler It is a specific type of compiler that compiles parts of the bytecode with similar functionality at the same time. As such, it reduces the compilation time and improves performance and is often a frequently referred topic among Java interview questions. 9. Define classloader. Define the types of classloaders Classloaders are a subsystem of JVM that is used to load class files. As such, it runs when the program is first run. The three types of classloaders are: the bootstrap classloader, the extension classloader and the system/application classloader. 10. Explain about class specifiers along with its categories Class specifiers are the keywords in Java that are used to define the access scope of the method, class or variable. It is an obvious topic for Java Interview Questions as it is frequently used in java projects. As such, the access specifiers and the four types and definitions of each are common topics of Java Interview Questions. Advance Java Interview Questions 1. Define features like abstraction, encapsulation, inheritance and polymorphism, how they are utilised in Java along with comparisons between them. While the features of Java have been mentioned previously, the features here have to be mentioned separately as they are an intrinsic part of many languages and define their inner working rather than being just a selling point or as a nifty property. As such, most programming languages, including Java, include them in their interview questions. Outside of this, the implementation varies between languages and in the case of Java, its implementation there is common among Java interview questions. 2. Explain about Java constructors and constructor overloading Becoming java developers are a frequently covered topic in Java interview questions. They refer to a type of method that is used to initialise the state of any other state of an object and memory is allocated to it. There are two types of constructors in java based on their parameters: default constructors and parameters constructors. Outside of this, there are additional topics that can be covered under Java interview questions. These include returning value, inheritance, overloading and making static. 3. The “this” keyword in Java The “this” keyword in Java is often a part of Java interview questions. as a reference variable that refers to the current object. The questions here can range from definition to uses to specific questions regarding specific situations. Outside of this, there are some more specific Java interview questions as presented below to get an idea about their in-depth knowledge The “this” keyword acts ledge of core java rather than just their working knowledge. These include: 1. Can Java save a file with a .java extension? Among the in-depth Java interview questions, this isn’t that highly advanced but there are also additional conditions such as running by java classname. 2. Can you execute code in Java before the main method Yes, code in java written in the static initializer block is executed before the main method. However, in Java interview questions, a similar question is whether it can run without a main method. 3. Can you execute a program in Java without the main() method. Yes, if the code uses the static block. However, this only works for those preceding JDK 1.7. 4. Can you assign reference to this variable? No. 5. Can you predict the output of the code in Java? This has been presented as one of the more thorough Java interview questions but it takes so many different variations that it can be considered as an entire sub-section of Java interview questions. The topics can range from finding the output of a code when the code uses tricky syntax to obfuscate the output, error finding to judge whether a code would run, finding errors that are stated to exist along with solutions along with explaining their workings. EE Java Interview Questions J2EE refers to the Java 2 Enterprise edition. The main application for this is in developing and deploying multi-ti3r web-based enterprise applications. As such, it can often be found applicable in companies. As such, a section has been dedicated here for some of the questions that may be asked in regards to J2EE. Explain J2EE This bears similarity to the core Java interview questions that were mentioned in the previous section. The definition should include not just about the full name and what it means, but also the functionality and primary features. Explain about the J2EE module. Explain about the different types of J2EE modules The J2EE module refers to a software unit that contains one or more J2EE components for the same container type. Outside of the definition, function and types, the Java interview questions here can range from defining each subtype and what they contain and explanation for each section. Struts in the J2EE framework The struts refer to the application development framework that is based on the application development framework that is based on the MVC. Struts and their components are often referred to in Java interview questions, especially in EE due to their relevance for development. Hibernate in J2EE Hibernate is a query and object service that allows for the expression of queries better than in SQL. This is an integral part of J2EE and the questions here can range from the definitions of Hibernate and HQL to questions regarding its uses, advantages and limitations and steps regarding practical questions regarding adding of Hibernate mapping files abd file extensions for mapping and configure Spring in J2EE Similar to Struts above, Spring is a lightweight open-source framework for developing enterprise applications. Again, similar to Struts the questions can range from definitions and uses to modules and expanding on each section. Topics to cover outside of Java interview questions Outside of the posted questions above, as the role for hiring increases in seniority, such forms of theoretical Java interview questions decrease in relevancy. That is because the people hired at the senior roles are expected to know about such topics either from previous roles and are more likely to work in roles such as management of teams, testing of the product and handling of customer management so while they have latitude in looking up minutiae of code, they should have the knowledge and expertise in regards to complex and unexpected issues along with an ability to mentor subordinates in such issues. As such, rather than asking Java interview questions on theoretical topics, the focus should be on their work and project experience with the subject. Some examples of the miscellaneous Java interview questions that can be expected are as follows: 1. What previous experience do you have using Java? 2. What frameworks, packages and libraries have you used in collaboration with Java? 3. What challenges did you face in your projects? 4. What other experience do you have using software’s similar to Java such as C++? Outside of Java interview questions regarding previous work experience and theoretical knowledge, questions regarding their general technical knowledge base are also expected in any interview. Conclusion The presented Java interview questions are a brief summary of the many possible Java interview questions that can be asked on this subject. Additional Java interview questions are available online on many sites and blogs. This isn’t even considering the various libraries and frameworks that Java offers. As such, while a theoretical understanding is helpful, as stated in the penultimate section, that cramming such Java interview questions isn’t as helpful as clear comprehension and on-hands experience.

Semi-Trailer Dimensions: Different Types of Trailers for Semi Trucks
This article describes semi-trailers and different types of trailers depending on the semi-trailer dimensions. So what is a trailer? What are the types of trailers for semi-trailers? Semi-trailers are trailers without a front axle. In the United States, the term is also used to refer to a trailer combination, also known as a truck and tractor-trailer. Most of the weight of the semi-trailer is supported by a tractor unit, a removable front axle assembly called a dolly or another trailer tail. Trailers are usually equipped with landing gear (legs that can be lowered) to support them when detached. Many trailers have wheels that are completely removable and can be moved (repositionable) to better distribute the load on the bearing wheel weight factor. Semi-trailers are more common for transportation than full trailers with face and rear axles. Ease of support is listed as one of the best semi-finalists. The two semi-trailers are called tandem trailers or tandem trailers. Another term used is "B train" or "road train" (if there are three or more trailers). The double trailer can be combined with a dolly or a "converter wagon". This is basically one to three additional axles placed under the front of the second semi-trailer. The first semi-trailer is connected to the power unit using the tractor's fifth wheel coupling, and the adapter dolly already connected to the second semi-trailer is connected to the first semi-trailer with a drawbar. Read below for a list of different types of semi-trailers for semi-tracks. Trailer type Flatbed trailer Flatbed trailers are today's most popular and commonly used semi-trailers. It is either 48 feet or 53 feet long and 96 or 102 inches wide. Lowboy. trailer The Lowboy is a semi-trailer that lowers the deck by two. One is just before the gooseneck and the other is just before the wheels. This allows the deck to be very low compared to other trailers. Refrigerated trailer Refrigerated trailers are also known as refrigerated trailers. Usually used to transport refrigerated or frozen products. The temperature inside this trailer can be controlled regardless of the weather outside. Conestoga Trailer The Conestoga Trailer is manufactured by Aero Industries. Build an innovative tarpaulin slide system that covers your valuable cargo without damaging the items below. This protects the termination or transfer of part of the goods or equipment. Step deck trailer Roll deck trailers are very similar to flatbed trailers, except that the maximum horror height must be 10 feet or less. The gradient platform is designed to withstand great features not possible with flatbed trailers. Mainly due to height restrictions. Dry truck trailer The dry track is a closed trailer. Dry truck trailers are the most common shipping container. These trailers are completely sealed. Therefore, charging is protected from external influences. Multicar trailer Multicar trailers are utilized to transport vehicles and trucks. They can carry 2-8 vehicles. If you need to tow multiple vehicles, use a double-decker trailer. Due to the height of the bridge, height cannot exceed 11.6 feet.
