For a fireplace that looks more natural, use tile materials that replicate the look of natural stone. These will give your tile fireplace a luxurious look. One way you can elevate the look of your tile fireplace design is to use travertine or marble tile. A modern approach is to use tile here, but then extend it above the mantel shelf and up the wall to the ceiling. The traditional use of tile is to use it immediately around the fireplace, just below the mantel, and on the hearth. ![]() For smaller fireplaces and surrounds, a colorful and patterned mosaic tile can look beautiful. This will keep it looking proportional to the space. ![]() The larger the fireplace surround and room, the bigger your tile should be. The trick to making the tile look good around your fireplace is to choose the right size. This popular building material is easy to maintain and keep clean while also adding color and texture to a room. When it comes to creating a unique yet durable look for your fireplace, you can’t go wrong with tile. An overly ornate Victorian fireplace mantel won’t make sense if you have a modern Craftsman home.Īmotherdesigner/Instagram 2. The mantel you choose should match the style of the fireplace and make sense in your home. Other options have the mantel built out of the materials used for the surround, such as brick, stone, tile, or marble. All you have to do is mount it to your wall and you have a complete fireplace mantel. You can find some beautiful and deeply intricate mantels that feature a wide variety of motifs. If you love the look of vintage, check out your local shops for a recovered fireplace mantel. Or add corbels underneath and paint it a particular color and have it blend in with the rest of the fireplace structure and the decor of the room. Leave it bare and let the beauty of the wood shine through. Thankfully, modern technology has addressed that issue, and your fireplace mantel is mainly there for looks.įor the most basic of mantels, you can mount a floating wood beam. It was originally added to fireplaces during medieval times as a hood to catch the smoke and ash generated by the fire. The mantel on your fireplace is the decorative shelf just above the surround. Fireplace Surround Ideas To Enhance Your Space ![]() 1/7/2024 0 Comments Mosaic web browser![]() ![]() ![]() The browser engine bridges the UI and the rendering engine. Browsers can also display other more advanced material like interactivity and animations made with JavaScript with internal JavaScript interpreters. The browser then communicates with the network to ask for all the documents that make up the page. This basically means that every URL has an equivalent set of numbers – the IP address – and the DNS translates it into language so we can type “” instead of “74.125.134.102”. After that, it sends a Hypertext Transfer Protocol (HTTP) request to the web server, which sends a response with HTML, CSS, and other content files to the browser. It does this by first performing a Domain Name System (DNS) look to find the correct IP address. When you search something on Google and click on a link or enter a URL in the address bar, the web server locates and sends the information you just requested to the web browser. The browser acts as a client to contact the web server and request information. Although they aren’t technically required, all these elements are usually found on every browser page to ensure usability. It includes the address bar, back and forward buttons, minimize/maximize/exit buttons, tabs, and the reload page button. The UI, or user interface, is basically the browser wrapper. For more of a deep dive to understand what happens between A (you clicking a link or typing in a URL) and B (you seeing a fully rendered web page), we can look closer at these elements to understand how browsers work. There are a few main components that make up the browser. 2015 – Microsoft Edge was born to combat Google.2011 – Opera Mini was released to focus on the fast-growing mobile browser market.2008 – Google Chrome appeared to soon take over the browser market.2007 – Mobile Safari was introduced as Apple’s mobile web browser and continues to dominate the iOS market.2004 – Mozilla launched Firefox as Netscape Navigator faded out.2003 – Apple’s Safari browser was released specifically for Macintosh computers instead of Navigator.This was also arguably the beginning of the browser wars, mainly between IE 3 and Navigator 3 as Internet Explorer inched ahead with new capabilities. 1996 – Opera started as a research project in 1994 that finally went public two years later.1995 – Internet Explorer made its debut as Microsoft’s first web browser.1994 – A noticeable improvement to Mosaic came Netscape Navigator.1993 – Mosaic was the first browser to allow images embedded in text making it “the world’s first most popular browser”.1992 – Lynx was a texted-based browser that couldn’t display any graphic content.Unlike today, this was the only browser and the only way to access the web. ![]() 1990 – The WorldWideWeb (not to be confused with the World Wide Web) was the first browser ever created by W3C Director Tim Berners-Lee, then renamed Nexus to differentiate from the actual World Wide Web.Before the web browsers we knew today, there were the first browsers, which are no longer in use or have highly evolved. There’s an entire history of web browsers. Why do different browsers respond differently to websites, and why is there more than one to begin with? How do browsers work and where did the need for cross-browser testing come from? By understanding the history and backend of some major browsers including Chrome, Safari, Internet Explorer (IE), Firefox, and Opera, it’ll be easier to understand what goes into developing and testing a cross-compatible website. More technically though, the browser is a software application that retrieves and displays information from a server including web pages, text, images, videos, and other content. Your browser allows you to shop online, watch videos, upload pictures, play games, and billions more. We all know the basic functionality of the browser - it’s what connects you with everything on the web. ![]() ![]() ![]() Installing applications using Google Chrome It is that easy to download the applications from the Microsoft app store. To download them, you will need to enter your Debit/Credit card details and then get them. ![]() Remember that some applications are paid. Through this method, you can easily download applications and can use them in a hassle-free manner.
![]() You can get a great phone that does almost everything that a new iPhone 15 can do for a fraction of the price. Hold the iPhone first: You may love or hate the way it looks and feels in person.ĭon't discount last year's model: Apple has a history of keeping recent iPhone models from previous years around at a lower price. Are they smooth? Or do they lag or stutter? We also look at how quickly the phone switches between horizontal and vertical orientations and how fast the camera app opens and is ready to take a photo. Of particular note are how graphics and animations look. We use benchmarking apps to measure the performance, alongside our own anecdotal experiences using the phone for our review. We also conduct a video playback test, which isn't always included in the initial review and is added later in an update. We assess how long the iPhone lasts during a typical day of use, and note how it performs during more focused sessions of video calls, media streaming and gaming. Battery lifeīattery testing is conducted in a variety of ways. We try out any new camera modes, such as Action mode that debuted with the iPhone 14 line. Photography is a major focus for the iPhone, so we take pictures and videos of various subjects in a variety of settings and lighting scenarios. Galaxy S23 offers a longer optical zoom.Discounted iPhone 14 Pro may be a better value.Find My Friends feature only works with other iPhone 15 phones. ![]() Dynamic Island brings better multitasking.The improved camera can automatically take people and pet portraits.USB-C port for more convenient charging.But the iPhone 15 is the most exciting upgrade Apple's standard iPhone has seen in years. ![]() ![]() Last year's iPhone 14 Pro may be a better choice if you can still find it through third-party retailers at a discount, particularly because it has a dedicated telephoto lens. These phones also have Apple's second-generation ultra wideband chip, enabling a new feature that makes it easier to find friends or family members in a crowd. They run on the same chip as the iPhone 14 Pro, the A16 Bionic, which should bring notable performance upgrades to those with an iPhone that's several years old. The iPhone 15 is available in two size options: the 6.1-inch iPhone 15 and the 6.7-inch iPhone 15 Plus. ![]() ![]() Once the fan and the lights shut off and the LCD screen displays “Attemp,” press the power button and the unit will boot up into normal mode.RAIDiator-arm Version 5.3.13 (for ReadyNAS Duo v2/NV+ v2) Download.

It’s not uncommon to spend an hour or so trying to take down one of the more formidable foes, learning their attack patterns through Souls-like trial and error. Trust me when I say that as the game progresses, encounters become quite challenging. Enemies are varied, especially the larger-than-life bosses, and every battle so far has managed to keep me on my toes. Speaking of combat, it’s an absolute blast. ![]() This leads to some awkward camera angles. Its movement is relegated to the right analog stick, which leaves you without a means to control the camera while directing the Rot. The other control gripe I have is when steering the amalgamated dragon Rot creature (more on the Rot in a second). There’s also a pulse button, default mapped to the left bumper button, which sends out an energy wave and allows you to activate set pieces and collect items. Attack and blocking commands are relegated to the shoulder buttons, not unlike God of War or Godfall, so holding down the left trigger serves to aim, which extinguishes the barebones lock-on entirely. To be fair, the lack of a solid targeting mechanic might have to do with how the buttons are mapped. While Bridge of Spirits does have a lock-on function for fighting, the game could have benefited from some kind of Zelda-esque Z-targeting. ![]() Balancing close quarter combat while trying to take down aerial enemies can result in some thrilling multi-tasking. Once Kena gains access to the bow mechanic, which is a transformation of her default staff, battles can get really intense. Movements are all extremely responsive, though parrying can be difficult to master and can feel a bit unfair at times.

Workbench requires a two button mouse, where right click operates pull-down menus and left click is used for all other purposes. Intuition also handles user input events, such as, input from the keyboard and mouse. Later versions of AmigaOS enhanced the interface with more complex object-oriented widget systems, such as gadtools.library and BOOPSI (AmigaOS 2.0 and later) and ReAction (AmigaOS 3.5 and later). Intuition manages the rendering of screens, windows, and gadgets (graphical elements, equivalent to widgets). Workbench utilizes the Amiga's native windowing system called Intuition to provide the graphical user interface. Under this concept, each drawer (folder) opens in its own window, rather than within a single browser under the now more common navigational concept. ![]() Workbench is a spatial file manager in the sense that it uses a spatial metaphor to represent files and folders as if they are real physical objects. ![]() These representations may be considered somewhat unusual by a modern user, but at the time there were no commonly accepted metaphors and Commodore chose to use different idioms from their competitors ( Apple had already pursued legal action to prevent other software companies from offering graphical user interfaces similar to its own). The desktop itself is called Workbench and uses the following representations: drawers (instead of folders) for directories, tools for executable programs, projects for data files, and a trash can as a folder intended to contain deleted files. a workbench for manual labor), rather than the now-standard desktop metaphor, for representing file system organization. The Amiga Workbench uses the metaphor of a workbench (i.e. From release 3.5 the operating system was renamed "AmigaOS" and subsequently "Workbench" refers to the native file manager only. "Workbench" was also the name originally given to the entire Amiga operating system up until version 3.1. It uses a workbench metaphor (in place of the more common desktop metaphor) for representing file system organisation. Workbench provides the user with a graphical interface to work with file systems and launch applications.

For integer types, the size and sign must also be the same.īoth the foreign key columns and the referenced columns can be PERSISTENT columns. The foreign key columns and the referenced columns must be of the same type, or similar types. The referenced columns in the parent table must be a an index or a prefix of an index. If MariaDB automatically creates an index for the foreign key (because it does not exist and is not explicitly created), its name will be index_name. Index prefixes are not supported (thus, TEXT and BLOB columns cannot be used as foreign keys). The columns in the child table must be a BTREE (not HASH, RTREE, or FULLTEXT - see SHOW INDEX) index, or the leftmost part of a BTREE index. The symbol clause, if specified, is used in error messages and must be unique in the database. RESTRICT | CASCADE | SET NULL | NO ACTION | SET DEFAULT The definition must follow this syntax: ] FOREIGN KEY See the Examples below.įoreign keys are created with CREATE TABLE or ALTER TABLE. However, only the syntax described below creates foreign keys.įrom MariaDB 10.5, MariaDB will attempt to apply the constraint. MariaDB simply parses it without returning any error or warning, for compatibility with other DBMS's. For example: CREATE TABLE b(for_key INT REFERENCES a(not_key)) Each option has distinct implications for data integrity, query complexity, and database size.Note: Until MariaDB 10.4, MariaDB accepts the shortcut format with a REFERENCES clause only in ALTER TABLE and CREATE TABLE statements, but that syntax does nothing. In conclusion, the choice between ‘ON DELETE CASCADE’ and ‘ON DELETE SET NULL’ in database design depends on the specific requirements of the application and the desired behavior when dealing with parent and child records. Retains child records, potentially leading to a smaller reduction in database size. May lead to a more significant reduction in database size due to cascading deletions. Requires additional consideration when querying to handle NULL foreign key values. Simplifies query, as there is no need to separately handle child deletions. ) Difference Between ON DELETE CASCADE and ON DELETE SET NULL in DBMSįoreign key values in child records are set to NULLĮnsures referential integrity by removing dependent records.Įnsures referential integrity by maintaining child records with NULL references. Example SQL Syntax CREATE TBALE parent_table_p (įOREIGN KEY (parent_id) REFERENCES parent_table_p(id) ON DELETE SET NULL This is another way to maintain reference integrity, allowing the child records to exist but with the NULL reference if the parent record is deleted. If you made the child table (referencing table) “ON DELETE SET NULL” this means if a record in the parent table (referenced table) is deleted then the corresponding entry or values in the child table (referencing table) will be set to NULL. The phrase “ON DELETE SET NULL” is not a standard option in most relational databases.
