Quick Reference Cards

A reference card or quick reference card is a concise bundling of common syntactic rules and idioms of a particular formal language. It serves as an ad hoc memory aid for an experienced user.
In spite of what the name reference card suggest, the term only tends to be used in the narrow context of programming languages or markup languages. However, this concept is now being adopted to portray concise information in many other fields.

Java JAVA Quick Reference41 KJava is a high-level programming language developed by Sun Microsystems. Java was originally called OAK, and was designed for handheld devices and set-top boxes. Oak was unsuccessful so in 1995 Sun changed the name to Java and modified the language to take advantage of the burgeoning World Wide Web.
Java is an object-oriented language similar to C++, but simplified to eliminate language features that cause common programming errors. Java source code files (files with a .java extension) are compiled into a format called byte code (files with a .class extension), which can then be executed by a Java interpreter. Compiled Java code can run on most computers because Java interpreters and runtime environments, known as Java Virtual Machines (VMs), exist for most operating systems, including UNIX, the Macintosh OS, and Windows. Byte code can also be converted directly into machine language instructions by a just-in-time compiler (JIT).
Java is a general purpose programming language with a number of features that make the language well suited for use on the World Wide Web. Small Java applications are called Java applets and can be downloaded from a Web server and run on your computer by a Java-compatible Web browser, such as Netscape Navigator or Microsoft Internet Explorer.

TeX Reference Card171 K
TeX is a typesetting system written by Donald E. Knuth, who says in the Preface to his book on TeX that it is "intended for the creation of beautiful books - and especially for books that contain a lot of mathematics". It is a fully programmable macro language used to specify how a document should be typeset. High level features for optical mark-up, as represented by Plain TeX, allow one to build additional levels leading to full logical mark-up.
Joseph H. Silverman
Updated! AMSTeX Reference Card 1.3110 KAt the moment, AMSTeX is one of the most widespread macro packages for logical mark-up. This package, introduced by the American Mathematical Society (AMS) is built on top of Plain TeX to greater or lesser extents and the user can use the optical mark-up of Plain TeX in addition to logical mark-up if desired. This results in the effect that the author can use a mixture of structural information and explicit layout information.

It offers functional improvements over sh for both programming and interactive use; these include command line editing, unlimited size command history, job control, shell functions and aliases, indexed arrays of unlimited size, and integer arithmetic in any base from two to sixty-four. In addition, most sh scripts can be run by Bash without modification.

LG G5 Review In-Depth

Can LG take on the Galaxy S7 with a metal design, dual-cameras and an accessory slot? Here's our first LG G5 review, focusing on LG G5 design and build, LG G5 specs, LG G5 cameras and LG G5 software and apps.
Alongside the Galaxy S7, the LG G5 is one of the biggest phones (not literally) to launch in 2016 – and we're not just talking in the Android world. It's one of the heavyweights and LG will be looking to set the market alight with the G5's alternative and innovative modular design.

Oppo RX17 Pro Review: Hands-on

We had time with Oppo’s new RX17 Pro. It may be blue and purple but how different is it to the similar OnePlus 6T and is it worth your time?
Should I Buy The Oppo RX17 Pro?
Oppo has made a solid mid-range phone in the RX17 Pro. Build quality is premium, fast charging is industry-best fast and the display is of high quality.But the price is high at 599€ considering the OnePlus 6T with a better processor starts at £499/€529. And while functioning as it’s supposed to, ColorOS is still unrefined for the western market with far too many changes to Android to recommend over competitors.

BlackBerry KEYone Review

BlackBerry soliders on with a curious Android device that gets nearly everything right. It’s not for everyone though, in fact, it’s not really for anyone. But if you want a physical keyboard you will absolutely love it.
Should I Buy The BlackBerry KEYone?
But then, the KEYone is the best BlackBerry phone for years. It has (finally) successfully melded classic BlackBerry design with the necessary mix of Android and nostalgia. Importantly, the latter is only faint this time – this is a device for 2017, not 2007.If you love your iPhone or Samsung, you’ll hate the KEYone and won’t even consider buying it. But if you’ve made it to the end of this review, chances are you’re weighing up a buy. If you think you’ll love the BlackBerry KEYone, then I’m pretty certain you won’t be disappointed. You’re part of a minority, but finally BlackBerry has a phone for you that doesn’t force you to compromise.

Google Pixel Review

Microsoft Surface Laptop 2 Review

Is there more to the Surface Laptop 2 than a lick of black paint? Find out in our full review.
Should I Buy The Microsoft Surface Laptop 2? The Surface Laptop 2 is a slightly odd one as it's not a huge upgrade on the original. That said, it comes in at the same price with a few upgrades and the new black colour.You get an 8th-gen Intel processor giving a nice performance boost as well as double the memory for the entry-level model. Battery life is a little down in our test but it's still a decent effort making this still one of the best laptop around.
