Getac V200 rugged Core i7 tablet PC outed

Rugged computer specialist Getac has outed its successor a sibling to the V100 convertible tablet PC, and as you might expect it’s no less sturdy. The Getac V200 has a 12.1-inch super-bright 1,200 nit multitouch-capable display, 2.0GHz Intel Core i7-620LM processor and WiFi b/g/n, but more importantly perhaps it’s MIL-STD-810G and IP65 compliant for resilience to dust, vibration, temperatures as low as -20 degrees centigrade and water.

Other specs include gigabit ethernet, Bluetooth 2.1, USB, VGA, RS232, eSATA, an SD card reader and PCMCIA, while GPS and 3G are optional. Buyers can optionally swap out the standard 320GB hard-drive for an 80GB SSD, too. Data security is taken care of with a smartcard reader, fingerprint scanner and hardware encryption, and you can swap the battery without having to completely shut down the tablet.

The touchscreen is resistive, which was an intentional decision: that means gloved fingers can use it, handy when you’re in icy conditions. We’re waiting to hear back on pricing.

Update: Getac tell us the V200 is priced between $3,799 and $5,099 depending on screen size and options ordered.Update 2: Getac also says the V100 will remain on sale alongside the V200, offering users a choice of screen sizes.

Eight Lenovo Thinkpads Hit Military Rugged Standards

Lenovo has announced that eight of its ThinkPad notebooks have passed military-standards for ruggedization, making them not only resistant to pressure, humidity, temperature, dust and vibration, but to a greater extent than some “mil-spec” rivals. The ThinkPad X200, X301, X200s, X200 Tablet, T400, T500, R400 and SL300 all passed durability tests despite not being specifically marketed as ruggedized models.

Lenovo are crediting their Active Protection System (which parks the hard-drive automatically if the laptop drops), roll-cage, shock-mounted hard-drive and spill-resistant keyboard for the successes. The tests covered:

Vibration (operational and non-operational) – Jostles and jolts the laptops to make sure they can withstand shocks

To coincide with the testing results, Lenovo are adding a high brightness, wide angle screen option to the ThinkPad T400 range, making it four-times brighter than previous displays and, thanks to an anti-glare coating, usable in direct-sunlight. The Lenovo ThinkPad T400 range starts at $1,350.

Press Release:

Lenovo Puts ThinkPad Laptops to the “Tough Test”: Meets Military Specs for Semi-Rugged Computing

RESEARCH TRIANGLE PARK, NC – February 24, 2009: Lenovo today announced that it is designating eight ThinkPad laptops for use in field and vehicle semi-ruggedized computing environments such as in public safety, utilities, construction and the military. The ThinkPad X200, X301, X200s, X200 Tablet, T400, T500, R400 and SL300 laptops meet a barrage of military specifications tests and are enhanced with specially-designed durability features such as an air-bag like protection system and a roll cage in select models. Because field computing requires excellent screen viewability, Lenovo is also adding a new optional 680-nit high brightness panel to its most popular laptop, the ThinkPad T400 laptop.

“ThinkPad is well known for quality, reliability and innovative security technologies for business computing,” said Tom Ribble, executive director, Worldwide ThinkPad Product Marketing, Lenovo. “The truth is we’ve always built tough laptops that can weather extreme conditions from hiking the rainforests of the Amazon to flying in space. You don’t need a PC that looks like a tank to excel in harsh environments, and unlike many of our competitors, we don’t put an extra charge on toughness.”

Optimized for Outdoors

As the adoption of laptops increases and connectivity options continue to expand, users are spending more and more computing time outdoors. That makes screen visibility extremely important. For a crisp and easily readable experience, Lenovo is equipping the ThinkPad T400 laptop with an optional high brightness, wide angle screen, making it nearly four times brighter than previous ThinkPad laptop screens. The high contrast screen eliminates reflections with its anti-glare finish. And by using energy-efficient LED technology, the laptop maintains long battery life.

Police Departments like the Conover Police Department in North Carolina are using ThinkPad laptops to turn their patrol cars into mobile offices. Reduced time spent at the station writing reports gives officers extra time on patrol to protect their community. Officers are using ThinkPad T Series laptops to write and print incident reports, issue tickets and conduct criminal background checks from their cars. For IT Director, Chris Niver, Lenovo’s engineering made ThinkPad laptops the easy choice.

Military Spec Tested Against the Elements

Baked, battered, blistered and blown with sand, Lenovo put the lineup of eight ThinkPad laptops through the gauntlet to pass a significant number of specifications for military-grade computing.

The ThinkPad laptops met tests for:

Low Pressure – Tests operation at 15,000 feet

Humidity – Cycles 95 percent humidity through the environment

Vibration (operational and non-operational) – Jostles and jolts the laptops to make sure they can withstand shocks

High Temperature – Simulates high heat conditions by baking the laptop up to 140 degrees

Low Temperature – Tests operation at minus 4 degrees

Temperature Shock – Fluctuates between minus 4 and up to 140 degrees to test operation

Dust – Blows dust for an extended amount of time

The tests confirm the durability and reliability that many customers already rely on to battle the elements. Geophysicist, explorer and expedition leader Pasquale Scaturro travels to the far reaches of the planet with his ThinkPad laptop.

“For over 180 days a year I can be found on the road traveling with my with my ThinkPad laptop -sweltering in the hot jungle terrain and surviving frigid arctic and mountain blasts, said Pasquale Scaturro, Exploration Specialists, Inc. “From bugs and humidity, to sand and dust, heat and cold, my ThinkPad laptop has been exposed to them all. I’ve logged more miles on my ThinkPad in the roughest and most extreme environments in the world than perhaps any person alive. From the heights of Mount Everest to the full length of the Nile, the world’s longest river, it’s been with me. The Active Protection System is a must in the rough environments I’ve taken this laptop into. Besides using my ThinkPad to help me navigate in my airplane when I’m flying in the African bush (it’s my real co-pilot) and send Internet dispatches to my website from Mt Everest, I depend on it to keep my geophysical business and my personal connections going. It’s withstood every imaginable environment on Earth and is still performing without missing a beat.”

Built Upon a Strong Foundation for Low Total Cost of Ownership

Lenovo engineers extra durability and reliability features into its ThinkPad laptops to help them survive all-weather conditions, lasting longer and outperforming competitors and leading to a low total cost of PC ownership.

Lenovo durability features include the:

Active Protection System – Temporarily parks the hard drive when the laptop detects a fall or sudden movement via an air-bag like system

Roll Cage – Serves as a protective frame around the internal components where the data resides and processing takes place with an extra top cover roll cage on the ThinkPad X301 laptop

Shock Mounted Hard Drive – Offers extra protection around the hard drive to protect data

Spill Resistant Keyboard – Withstands spills of up to two fluid ounces on select laptops allowing liquid to drain beneath the keyboard

In case of the unexpected, Lenovo offers Warranty and Accident Protection plans to help customers protect their PC investment. Lenovo also offers ThinkPlus Priority Support to give businesses around the clock technical telephone support, priority routing of calls and quick onsite repair. For an even faster response, ThinkPlus Priority 4 Support provides onsite repair within four hours after the original troubleshooting. Online Data Backup services are also available.

Built upon a strong foundation, Lenovo’s laptops offer the latest technologies with models including solid state drive storage for reliability, switchable graphics for longer battery life and the latest Intel® Centrino 2 processor technology for fast processing. They also come with choices of large hard drives, multimedia like Blu-Ray DVD players and a host of wireless connectivity options including WiMAX, mobile broadband, WiFi, Bluetooth and GPS. Lenovo has also collaborated with AT&T and Ericsson for price reductions on ThinkPad laptop AT&T mobile broadband connectivity. Additionally, the ThinkPad X200 Tablet is the first Tablet to offer WiMAX connectivity.

Pricing and Availability1

The ThinkPad T400 laptop with the high brightness screen is available through Lenovo business partners beginning immediately. Pricing starts at approximately $1,350.

5 Best Tough Rugged Laptops To Buy

5 best tough rugged laptops to buy [Lenovo, Panasonic]

278

The laptop family emerged as a go-to system once people decided to trade off power for mobility. Nowadays, they are present in all spheres of computing, and more than ever, in some specialized departments.

Your first thought about portable computers, besides performance and battery life, must be durability. Standard laptops can’t sustain even moderate physical damage or water spill. However, there is a special niche of rugged laptops, the sturdy machines that can and will move on through numerous challenges.

Those laptops are rare and often pricey. But, if you are working in extreme conditions and want your laptop by your side, rugged laptops are just the thing for you.

For that purpose, we compiled the list of top 5 laptops that can withstand more than you’ll expect.

Top indestructible laptops for most demanding conditions

Before we start with the list, it’s essential to mention two safety standards that evaluate sturdiness on electronic devices.

IP (International Protection rating) is the rating system that evaluates protective features of the device from both solid and liquid effects and it is composed of two numbers. The first number stands for solids (dirt, dust), while the second one stands for liquid (water) resistance. So, basically the higher the number, the better.

MIL-STD (Military Standard) is the second standard. Simply put, the devices that pass the evaluation are approved for military use. There are two main tests: 810G and 810F. MIL-STD is very important and means a lot when differentiating rugged devices.

Panasonic is an industry giant, but neither they produce widely popular smartphones nor laptops. However, they are known for their quality and create some of the best-specialized products in the world. In this case, great rugged devices. Besides the rugged smartphones/phablets (ToughPad), they have a few series of Toughbook laptops. We are talking about mostly semi-rugged devices.

Their best model is probably the Toughbook 54, from the Toughbook 5 series. Comparing to most of the other rugged laptops, Toughbook 54 is much lighter and thinner.

It weighs only around 2 kg which is remarkable since most of the standard laptops are heavier. Even though it is not as rugged as fully-rugged devices, it can withstand falls from up to 3 feet on a hard base. In addition, it has confirmed the MIL-STD-810G license and the IP51 rating. That means that it is protected from dust and dripping water. The storage drive is caged and resistant to shock.

Core Php Interview Questions And Answers In 2023

Introduction to Core PHP Interview Questions and Answers

Core PHP is actually the meaning of very basic PHP. It is normally used for creating some dynamic web pages for displaying to the end client through their own browser. It has basic core logic of programming on the server side and displays on the client side based on the expected logic.

If you are looking for a job related to Core PHP, you need to prepare for the 2023 Core PHP Interview Questions. It is true that every interview is different as per the different job profiles. Here, we have prepared the important Core PHP Interview Questions and Answers, which will help you get success in your interview.

Start Your Free Software Development Course

In this 2023 Core PHP Interview Questions article, we shall present the 10 most important and frequently asked Core PHP interview questions. These interview questions are divided into two parts as follows:

Part 1 – Core PHP Interview Questions (Basic)

This first part covers basic Core PHP Interview Questions and Answers.

Q1. Two very common functions used in core PHP for a long time. Those functions include () and require(). Please give some clear differences between including and requiring a function for core PHP.

Include() and require() are both used to include some specific file with the requesting page.

The main difference between them is:

If the developer use requires to include the file, then somehow the process throws some fatal error during execution for unavailability of the file, then execution of the process will entirely stop. But if the developer use includes for including the file, then the entire process will not stop; it will ignore the fatal error and go for executing the next step without stopping the process.

Q2. Suppose we are willing to get the IP address for some client who is using PHP developed web application. Please explain how we can get that IP information in PHP?

There have several options for fetching IP addresses of the client execution machine in PHP. The developer can able to write some critical scripts for fetching those data externally.

But one of the popular and very basic approaches to fetching IP addresses is:

$_SERVER[“REMOTE_ADDR”];

Q3. Explain in detail the difference between the two popular functions of PHP, unset() and unlink().

The main difference between them is:

If the developer used unset() on any file, then that file reference is going to be undefined for the entire application, whereas if the developer mentions one file as unlink, then that file will be removed from the directory and as well as not available for the entire application.

Q4. There are several error types available in PHP. Explain some of the major error types which are very frequently used for PHP applications and give the proper difference of them.

There is the common Core PHP Interview Questions asked in an interview. Several responsibilities normally need to follow by a Core PHP tester in the current IT industry.

Normally in PHP, we are handling three kinds of errors:

Notices: This is just given one notice of wrong coding or execution. It is a very simple and mostly non-critical error that normally occurred script execution time. Suppose an application trying to access some undefined variable; then this kind of notice will come.

Warnings: It is again not that much critical error, but still, any wrong execution warning will be given without stopping the normal execution of the process. An example is, including a function used, but some file is missing in the directory, then the warning will be given, but the process will execute successfully.

Fatal: This is one of the most important errors that came in PHP script execution. It mainly causes the termination of the process by giving a proper explanation. An example is, trying to access some nonexistent object or requiring file uploading, but the file is missing.

Q5. Explain in detail about the difference between GET and POST in the PHP application.

Some of the key differences between GET and POST in PHP are given below:

GET information always passes through a URL, so it is always visible to everyone, whereas POST information is embedded with the request and sometimes it is in the encoded format, so it will not able understandable or visible to the normal user.

GET have some restriction on handling the request, define characters are 2048. Whereas POST doesn’t have this kind of restriction at all.

GET only allows require ASCII data, whereas POST does not have this kind of restriction.

Developer common approach to use Get for fetching data, whereas POST is used for inserting or updating.

Part 2 – Core PHP Interview Questions (Advanced) Q6. Suppose the developer needs to enable some of the error-reporting utilities in PHP. How can it be done, please explain in detail.

Displaying an error message is one of the key requirements, especially in debugging the developer’s error; it normally displays the number of lines of the script where a fatal error got generated. The developer can display this error on the possible page by giving the below command:

error_reporting(E_ALL)

But for initializing or activating of displaying error in PHP application, the developer needs to follow any of the below approaches:

Display_error = ON in php.ini

Ini_set(‘display_error’, 1) in the specific script file

Q7. Explain in detail about Traits in the PHP application.

Traits are one of the popular mechanisms specifically for the PHP developer. This mechanism help the developer for allowing to create some reusable code again for the PHP language application in case of those objects where the inheritance objective is not fully supported. In the case of Traits, not possible to inheritance by its own mechanism. It is one of the key requirements that PHP developers should know about the key and powerful features of the language before starting development in PHP.

Q8. Suppose one constant has been defined in one of the PHP scripts. Now developer needs to change that constant value during the execution. Is it possible to do? Explain?

If one value is declared as constant in PHP, then it will never be changed by any process during execution. Therefore, a constant value needs to be assigned at the time of initialization.

Q9. Is it possible to extend one class that is defined as final? Explain?

There are the most popular Core PHP Interview Questions asked in an interview. Some popular test cases in the current IT industry. If the developer defines one class as final, then extending that class is absolutely not possible. If one class or method is declared final then creating a child class and method overloading or overriding both are not possible.

Q10. Explain in detail about _destruct(), and _construct() methods available in PHP classes.

Every PHP object should have two methods called constructor and destructor. Both methods are mainly defined in the build-in. The constructor method is normally called immediately after creating one new instance of the specific class, normally used for initializing all the properties of a class. Whereas the destructor methods are mainly used to release the object of the class from the application memory. The destruction method does not require passing any parameter.
