Sometimes you just want to browse and listen to your album collection at the office without having to load it all into a portable music player. Pandora and Last.fm are great web services that can help you discover new music, but they won’t let you specify your own music playlist. Streaming music from within a home network is easy with iTunes and Windows Media Player; what’s trickier is getting access to your 100GB music library while away from home. We’ll teach you how to turn your library into an Internet radio station with Apache server software and a little-known program called netjukebox. You’ll be able to browse your collection via a gallery of album cover art, stream custom playlists, and even download entire albums as zip files.
The first thing you'll need to do is set your desktop up as an Apache server.
With the prevalence of software available for many distros, why would anyone want to compile software from source? Compiling allows you to custom-fit a program to your particular hardware configuration and CPU architecture, which is useful if a program has no binary that is compatible with your processor. However, this is seldom a problem these days, since most computers now use 32 or 64-bit x86 processors. In the past, Linux enthusiasts often compiled programs from source to wring the greatest possible performance out of their hardware. More recently, this has mostly become a non-issue due to the increases made in computing speed; while compiling may offer a slight performance increase, it is not enough to really make a difference.
Although the introduction of package management on most distros, less diversity in CPU architecture among the user base, and massive increases in hardware speed have largely reduced or eliminated the need to compile software yourself, there are still a few instances where you would have to do so. Although the various official and unofficial software repositories for Ubuntu and other distros include most of the tools that the average user would need for any given purpose, the repositories are not completely comprehensive.Old packages sometimes get dropped and updated versions are often slow to be added. It may also take a release cycle or more for brand-new programs to be included.
While Ubuntu and Debian have “backports” repositories that have fairly new packages in them, many other distros do not have such a resource. For large projects with large community support, the developer may offer nightly builds, but this is not the case for most projects. The only reliable way to get bleeding-edge software (stability issues aside) is to either find a repository that has it or download the source code from the developer and build it yourself.
Looks like your system is on the fritz again -- it refuses to boot your operating system. What do you do now? You can take it a tech shop and have "experts" investigate the problem, but that a costly option. Even if your computer can’t load Windows, there is still a way to fix boot problems without reformatting. With the right boot CD, you can perform your own troubleshooting dianosis the cure whatever ails your PC. Our guide will show you how to make a powerful boot disk that'll let you do more than just access a DOS prompt. You'll be able to run processor stress tests, memory scans, edit partitions, and even extract hard drive data.
More likely than not, you’ve been asked in the past to help fix one of your friend’s or relative’s computers. Most of the time, the problems you’ve been brought in to remedy are basic malware or virus infections that you can address by grabbing the appropriate diagnostic and software removal tools stored in your trusty USB toolkit. But once in a while, you’ll be faced with a novice struck with the most basic and frustrating of problems: forgetting their Windows administrator login password. With no way to get into the system, you can’t even perform basic maintenance, let alone a thorough tune-up. Formatting is always an option, but we consider that a last resort. (Plus, guess who’s going to have to help reinstall all the programs lost after a wipe?) But all hope is not lost. There are a few ways to actually retrieve a lost Windows account password. Read on and we’ll show you the light.
These days, most people have at least one computer and a large collection of media files. The conventional practice for most people has always been to have redundant copies of their media collection on their various computers. While this system technically works, it is highly inefficient and creates the unnecessary task of keeping the media collection on each computer synchronized and up-to-date with the others. A far better solution is to keep all the media on one computer and stream it as needed to the other machines over the network.
Streaming technology has been around for over a decade and is something that most people are at least a little familiar with. (Youtube uses streaming flash-based video to work) In the past, playing large files over the internet was usually pointless due to the fact that the software of the time required the whole file to download (often on slow connections) before the media could be played. With streaming media, the remainder of a file is fetched as the first part it is being played, so there is no need to wait to get the whole thing before watching it. The video quality on early streaming media was often quite bad, (a trade-off between quality and speed was necessary when most people were stuck on dial-up) but with the near-ubiquitous availability of broadband in most urban and suburb areas today, high-quality streaming media has finally become practical.
We have assembled this guide to help you set up a cross-platform media streaming service using a Linux computer as a server. With our guide, you will be able to stream media to any other computer you own. Other guides on the subject discuss how to set up a Samba-based solution, but we feel that our solution is simpler and easier since you only have to install and configure one program instead of several. For this purpose, we use GNUMP3d. GNUMP3d is a program that makes media available through a web-based interface. Instead of using the Samba protocol, GNUMP3d uses ordinary HTTP to get the job done.
If you want to take full advantage of your PC’s audio potential, you should connect your rig to your A/V receiver and passive speakers—or a really good set of powered speakers. But accomplishing this task is often tricky, thanks to a combination of digital rights issues, proprietary surround-sound algorithms, and evolving connection standards.
Computers outfitted with Blu-ray drives and certain late-model videocards can deliver Blu-ray video over HDMI, but getting HD audio that way is another issue. An HDMI cable can carry both high-definition video and up to eight channels of high-definition audio (front left and right, front center, rear left and right, side left and right, and low-frequency effects). Blu-ray discs are typically encoded using Dolby TrueHD, DTS-HD, or DTS-HD Master Audio; all three of these eight-channel lossless compression codecs can deliver bit-for-bit perfect copies of the original movie soundtrack. Here lies the rub: PCs currently cannot output audio encoded in any of these formats over HDMI.
A properly outfitted PC running CyberLink’s PowerDVD 8, however, can decrypt and decompress Dolby TrueHD and DTS-HD and output it as uncompressed eight-channel LPCM (linear pulse code modulation) to HDMI. However, while videocards based on newer Nvidia GPUs are outfitted with HDMI, they’re all limited to two-channel LPCM (linear pulse code modulation) audio over HDMI, and that’s only if your motherboard has a S/PDIF-out header
AMD’s RV7xx-series cards can deliver uncompressed eight-channel LPCM audio over HDMI because they route the signals over the PCI Express bus. For integrated graphics, motherboards with Nvidia’s GeForce 8300 chipsets (for AMD CPUs) and GeForce 9300 or GeForce 9400 chipsets (for Intel CPUs), and those with Intel’s G35 Express, G45 Express, and G965 Express chipsets can do it, too.
We highlight the four most common PC audio scenarios. Pick the one that fits your situation and we’ll show you the best way to integrate your PC into your home-theater system.
In our opinion, no artistic medium offers a better opportunity to express a PC gamer’s individuality and inappropriate sense of humor like a personal decal “spray” projected on your enemy’s spawn room wall during a multiplayer match. While Valve has made it a mostly painless process to import spray images into their Source engine-based games, the difficulty still lies in creating an original image you can be proud to vandalize next to an enemies corpse. And since no game offers more opportunities to grief friends and enemies than Left 4 Dead, we’re going to show you a flawless technique for creating your own ‘writing on the wall’, pun absolutely intended.
Hard drive encryption sounds like an intimating concept, mostly because it is. The thought of taking your precious files, then using a mathematical formula to convert them into random noise before scattering them back across your disk is a hard sell. The harsh reality is, mobile computing is on the rise, and so is laptop theft. Depending on who you ask, anywhere from 500,000 to over 1,000,000 laptops are lost or stolen in the US each year. In some cases, the data on the hard drive is often more valuable than the machine itself.
To determine if disk encryption is something you should be considering, simply ask yourself if your PC contains anything you wouldn’t want posted publically on the internet. If the answer to this is yes (and I assume for most of us it is) then encryption is worth considering.
The good news is, you no longer need to be a member of the CIA to lock down your machine with government level encryption.In fact, one of the most highly regarded and powerful encryption tools available is both free, and open source (our favorite combination!) True Crypt allows you to protect either all your data, or only what you choose. You can mask your boot drive and sensitive documents, while leaving your games or other non generic data in the clear. While no encryption process is without risk, True Crypt is designed to put your mind at ease, and takes no chances with your data. The process can be reversed at any time even without being able to boot into windows.
So if your ready to get started click the jump to learn step by step how to protect your data.
Malware is everywhere. You can't browse on any Internet tech forum without someone mentioning this word (with disdain), usually in search of a remedy after being infected with spyware. No matter how careful you are, we’re guessing that many of you have had malware inadvertently installed on your system and may have even ended up reformatting your computer as a last resort. While that may have been the most thorough solution, it is in a sense admitting defeat. Or worse yet, you took your computer to get cleaned and was charged anywhere from $50-300 -- a high price for humiliation. But don't fret, because you can actually purge your system of malicious software for free! Just follow our comprehensive guide.
Seadragon image zooming software is one of the more interesting software technologies coming out of Microsoft Research Labs. Its implementation in web applications is potentially a big leap in the way we view images online. One such implementation is Deep Zoom, an Ajax-powered online viewer that lets you view, zoom, and pan through high-resolution photos and images in a way that is incredibly fast and smooth, regardless of the original image’s pixel density. Companies adopting this tech include the Hard Rock Café, which utilizes it in its music memorabilia showcase. Microsoft also developed and released a mobile application for Seadragon in the form of a really cool iPhone app which lets you view Deep Zoom image files.
But what if you want to turn your own photo albums into a Deep Zoom gallery? With Microsoft’s Deep Zoom Composer, you can now create a high-tech hassle-free photo album allowing you to display your images online using the Seadragon plug-in. We show you how with our comprehensive step-by-step guide!
