The Car Repairs You Can (Seriously) Do Yourself, Despite Your Abilities Replacing belts is not something you just swap, at least on newer cars. On only cars, like early 80s or older, it was feasible. With cars from that era there was often a lot of room within the engine bay. On anything from the 90s on the bay is so cramped that you're going to have to do a lot of dismantling to get at belts. And if you're looking at swapping the timing belt then on some cars you might even have to lift the engine. Something like the alternator has the potential for being nearly as bad, depending on where the automaker likes to stick it. The first thing anyone considering to work on their car should do is buy a service manual. Brakes are relatively easy to do, but it's obviously a critical component on the car and there are things you need to keep in mind.

How to Calibrate Your HDTV and Boost Your Video Quality in 30 Minutes or Less Don't know about you... but TVs I've owned have Store and Home modes, Store is horribly bright, high contrast, Home is sensibly done. Last time this article came around it only needed a DVD player. Now you've made it even harder to do. You *can* use a DVD player, but considering no DVD player is capable of 1080p/i display, it wouldn't make much sense. That said, "Store" or "Cinema" or "Vivid" is the mode warned against in the open.

Developing Google Chrome Extensions It's no secret that my favorite browser is Google Chrome. I like it because it's fast, reliable, it doesn't crash (very often), and it looks good. There's also something else which I find even more valuable. It's the fact that you can build an extension for it using only HTML, CSS, and JavaScript. So at the end of this article you will find a working Chrome extension which uses most of the techniques explained below. If you're looking for a quick solution, you could also download the Chrome App Maker from Envato Market, which makes it very easy to create Chrome apps and extensions. I always encourage people to use better tools to speed up their workflow. Thankfully there is a way to test your extension without having to upload it to Chrome's web store. Make sure that you check Developer mode and click the Load unpacked extension... button. Here's a diagram of the architecture for a Chrome extension: And now let's take a closer look at each element within the architecture.

storage Overview This API has been optimized to meet the specific storage needs of extensions. It provides the same storage capabilities as the localStorage API with the following key differences: User data can be automatically synced with Chrome sync (using storage.sync). Your extension's content scripts can directly access user data without the need for a background page. A user's extension settings can be persisted even when using split incognito behavior. Manifest You must declare the "storage" permission in the extension manifest to use the storage API. Usage To store user data for your extension, you can use either storage.sync or storage.local. When Chrome is offline, Chrome stores the data locally. Confidential user information should not be stored! The storage.managed storage is read-only. Storage and throttling limits chrome.storage is not a big truck. Examples The following example checks for CSS code saved by a user on a form, and if found, stores it.

How to Take Your First Coding Project from Start to Finish I've used various versions of Windows for years, Linux in various flavours for another few years, and OS X for about 2-3 years total. I'm now a convert to OS X (though proudly not part of the cult of Mac — I enjoy the OS, I don't want Jobs' offspring) for general desktop use, switching to Windows for gaming. I find app quality is generally significantly higher on OS X than Windows (and certainly Linux). Do note the word "generally" — some of this stuff is cross-platform and in some cases Windows offers something better! The drawback of this is that most of it costs a couple of bucks, but that's a small price to pay if you're using your computer for various tasks daily. The UNIX core and bash are very important to me. User experience also plays a large part. Then there are the extras, like the *virtual* immunity to malware.

How to Build a Computer from Scratch, Lesson 4: Installing Your Operating System Ah, good eye! So, generally, your motherboard runs all RAM at the lowest speed (correct me if I'm wrong on any nuance of that particular fact, guys). As I mentioned in part 2, RAM speeds don't really matter. You're not going to get any noticeable difference from 300MHz in your RAM. However, where those RAM speeds DO come in useful is if you overclock your processor. Many of today's processors are tightly linked with the RAM, meaning that if you raise the clock speed of your processor, you also raise the clock speed of your RAM. So in the end? RAM speed do provide performance increase, visible in memory intensive task, such as photo editing, CAD or gaming. Your problem is easy to solve. Hope this helps. :) (please keep posted) I had this problem with my new build I bought some 1600 ram but it was running at 1333 on auto. Also, if I recall correctly, there are dividers associated with the bus speed and memory speed so it's still possible to overclock the CPU and keep the RAM in spec.

How to Make a Chrome Extension If you’re wondering how to make a Chrome Extension, Chrome’s extension documentation is great for basic implementations. However, to use more advanced features requires a lot of Googling and Stack Overflow. Let’s make an intermediate Chrome extension that interacts with the page: it will find the first external link on the page and open it in a new tab. manifest.json The manifest.json file tells Chrome important information about your extension, like its name and which permissions it needs. The most basic possible extension is a directory with a manifest.json file. That’s the most basic possible manifest.json, with all required fields filled in. Load your extension into Chrome To load your extension in Chrome, open up in your browser and click “Developer mode” in the top right. When you change or add code in your extension, just come back to this page and reload the page. Content scripts A content script is “a JavaScript file that runs in the context of web pages.”

Getting Started: Building a Chrome Extension Extensions allow you to add functionality to Chrome without diving deeply into native code. You can create new extensions for Chrome with those core technologies that you're already familiar with from web development: HTML, CSS, and JavaScript. If you've ever built a web page, you should feel right at home with extensions pretty quickly; we'll put that to the test right now by walking through the construction of a simple extension that will fetch an image from Google using the current page's URL as a search term. We'll do so by implementing a UI element we call a browser action, which allows us to place a clickable icon right next to Chrome's Omnibox for easy access. Clicking that icon will open a popup window filled with an image derived from the current page, which will look something like this: If you'd like to follow along at home (and you should!) The very first thing we'll need to create is a manifest file named manifest.json.

Terminology, Syntax, & Introduction - A Beginners Guide to HTML & CSS Before beginning our journey to learn HTML and CSS it is important to understand the differences between the two languages, their syntax, and some common terminology. As an overview, HTML is a hyper text markup language created to give content structure and meaning. CSS, also known as cascading style sheets, is a presentation language created to give content style and appearance. To put this into laymen terms, HTML determines the structure and meaning of content on a web page while CSS determines the style and appearance of this content. Taking this concept a bit further, the HTML p element is used to display a paragraph of text on a web page. Common HTML Terms When getting started with HTML you are likely to hear new, and often strange, terms. Elements Elements are designators that define objects within a page, including structure and content. Tags Elements are often made of multiple sets of tags, identified as opening and closing tags. <a>... Attributes HTML Document Structure & Syntax <!

Stream Your Music Online From Wired How-To Wiki Vintage radio photo by monogatari via Flickr You've spent a lot of time and money collecting digital music. But let's say you want to take that library to go? This article is a wiki. Step 1: Host it somewhere Most web hosts offer data plans around $10 per month that come with plenty of storage and bandwidth to hold and serve your music. Besides the cost, you trade off a good deal of control over the data because it resides on some machine out there in the ether. Hosting music on your own computer using a broadband connection is a preferable option, especially since you know exactly where it is and there's is no need to transfer your music anywhere. Tip: Webmonkey.com has an excellent introduction to using Dynamic DNS.Tip: Dan Hilgert also has an explanation of his Dynamic DNS setup and streaming music guide. Step 2: Create a playlist Perhaps the easiest way to get your music online is to use your favorite music player. Extended M3U The XSPF format is below. <?

How to Create a Chrome Extension in 10 Minutes Flat One of my favorite things about the Chrome web browser is how extensible it is. It seems like there is a Chrome plugin for just about everything you could ever possibly want. But, have you ever wanted to create your own Chrome extension? In this tutorial I am going to show you how to create a basic Chrome extension in about 5 minutes—no joke! What we are going to build I’m pretty obsessed about the speed of my website, so I often utilize sites like GTmetrix to check my site speed, just to make sure it isn’t slowing down. I’ll often check other sites that I’m on as well, so I can see how they compare. Well, wouldn’t it be nice if there was a Chrome extension that allowed you to use GTmetrix to check the site speed of whatever site you happened to be browsing, just by clicking a button? I checked the Chrome Web Store and there wasn’t an extension that performed this action, so that’s exactly what we are going to build today. What is a Chrome Extension? <!
