You will want an HBA (Host Bus Adapter) or a RAID card that has had it's firmware flashed to IT mode.
The reason is RAID cards interfere with the way the drives communicate with the OS. ZFS likes direct access to the drives to manage them and maintain data integrity. RAID controllers cause this communication to be broken. The system can still work with a RAID controller in place while using ZFS but you'll have lost the biggest features that make ZFS what it's known for.
ZFS doesn't care about using different controllers or chipsets. If the BIOS allows you to change the onboard controller from RAID to AHCI then that should be fine. These drives can be mixed with drives on other controllers like an HBA or an IT flashed RAID card.
Free and Open-source Alternatives to Common Programs
1.0 - Thread created
1.1 - Thread revamped with new info and added links.
1.2 - Added Index (placeholder)
With the advent of SteamOS, a good portion of gamers will likely switch to using it for their gaming needs. It won't really be long before more games start supporting Linux natively; newer games will definitely be supporting it as early as 2014, older games are constantly being ported over. Gaming on Linux is gaining momentum, but what about other productivity tools? Windows is still the king of OS's due to the wide range of applications natively supported, from Office to Graphics tools to 3D modelling, CAD/CAM and many other areas. Most of these applications are proprietary and closed-source and won't run on Linux natively.
The purpose of this topic is to highlight some of the many free and/or open-source alternatives to many proprietary Windows programs. Free doesn't necessarily mean open-source, and that difference will be highlighted where applicable. Open-source software isn't restricted to Linux only - many of them can be cross-platform. Many of them can also be cross-compiled from Linux source to run on Windows. Proprietary alternatives are only included for programs that are both low-cost and worth paying for.
One caveat to be aware of: The programs listed are merely alternative options to proprietary tools. In some specific cases, they won't act as replacements for the paid programs, due to paid programs having a vastly superior feature set. However, for the average user, the free alternatives are more than adequate. I personally tend to look at what people have done using the free alternative and compare them to the paid option, comparing their capabilities and not their specific feature sets. Of course, this may change in the future, due to the open-source nature of most of these programs: the necessary functionality can be added in my anyone.
So, let's begin!
1.0 - Microsoft Office
2.0 - Adobe Photoshop
3.0 - Adobe Illustrator
4.0 - Adobe Premiere/After Effects
5.0 - 3D Graphics (Modelling, Animation)
6.0 - Digital Painting
7.0 - Development Tools
8.0 - Desktop Recording/Streaming
9.0 - Media Player
10.0 - Gaming
11.0 - CAD/CAM/CAE

14.0 - Email Clients
15.0 - Linux Terminal-based
16.0 - Antivirus
17.0 - PDF Tools
18.0 - Virtualization
19.0 - Miscellaneous
Perhaps the most widely used and adopted set of tools for productivity. There are, however, more than a fair share of free and open-source options that are on par with Office, with one key exception: the free alternatives aren't capable of saving to .docx or any of the newer Office formats, but they are capable of reading them. That's not a major problem though: it's recommended to use the older .doc format due to being easier to work with. PDF is also a far superior format for sharing documents.
1) OpenOffice.org - This is usually the first option to come to mind, and it's been around for a while. Contains all of the replacement tools for Office. However, as some of you already know, it's somewhat lacking in features. Cross-platform.
2) LibreOffice - a fork of OpenOffice, with a wider range of features, and is more updated. I personally use this instead of OpenOffice and it's amazing. Cross-platform.
3) KOffice/Calligra Suite - Built into KDE. It may be possible to install it as a standalone application with the necessary dependencies. Contains a wide range of tools for everything Office related. Some older versions of KOffice is available on Windows.
4) TexLive - Alternative for MS Word. Specifically useful for Scientific documents (LaTeX).
5) WPS - Formerly known as Kingsoft Office, WPS is a newly updated version. Runs on iOS, Android, Windows and Linux, and capable of working with .docx and .xlsx files (compatibility and formatting issues aside). Exports to PDF as well, much like LibreOffice.
1) Google Drive - Can't say much more. Full range of Office tools online, seamlessly synced between devices. Google has also been promoting QuickOffice, which is a set of tools available on Mobile devices with Drive integration.
2) OneDrive - Microsoft's own set of online Office tools, similar to Google Drive.
High up on the list of productivity tools used by graphics designers and digital painters.
1) GIMP - widely seen as the best Photoshop alternative on Linux. It is also cross-platform.
2) GIMPshop - Similar to GIMP, both open-source and cross-platform.
3) Krita - part of Calligra Suite. It's primarily a digital painting program, which Photoshop is capable of. Linux only, with an experimental version available for Windows.
4) Scribus - Specialized tool for creating publications. Cross-platform.
1) Paint.NET - An advanced version of MS Paint, but contains many of the basic features found in Photoshop. Available on Windows only, as it depends on .NET Framework.
Perhaps the best Vector-based graphics tools. Photoshop has some vector capabilities, but Illustrator is far superior.
1) Inkscape - great replacement for Illustrator. Cross-platform as well.
2) LibreOffice Draw - part of the LibreOffice package. Cross-platform.
3) Karbon - integrated into KDE in the Calligra Suite, making it Linux only. However, there are ways of installing KDE packages on Windows. Should be able to install it without KDE with just the dependencies.
4) Xara Xtreme - Looks to be an excellent Vector-graphic editor. Available on Linux and Windows.
Adobe Premiere/After Effects
These two are generally combined as each performs a specific group of tasks. Premiere focuses on editing, while After Effects focuses on compositing and visual effects. Most open-source options combine these features into a single application - which is great.
1) Cinelerra - perhaps the best option available. There are two versions, a community maintained one as well as an official one. The community version is called cinelerra-cv and is available on most Linux distributions. Not cross-platform afaik.
2) Kdenlive - Similar feature set to cinelerra, but more along the lines of Premiere. Kdenlive is available on Windows through a VM image.
3) OpenShot - Another option instead of Cinelerra. Primarily on Linux, but can be cross-compiled on Windows with the right set of tools (Cygwin, etc).
4) Avidemux - Cross-platform and open-source. Very simple video editing, and encodes in multiple formats.
5) LiVES - Available on Linux and OS X. Similar feature set to Cinelerra.
6) Blender - primarily a 3D modelling program (will go into more detail below), but includes a non-linear video editor. Runs on python, which is cross-platform.
1) Lightworks - there's a free and premium version available. The free version is free forever. So far, Lightworks is Windows only. The Linux version is in beta.
There are many other free video editors out there. A Google search will reveal at least 10 other options.
Autodesk Maya/3ds Max, Cinema 4D
3D modellers have perhaps used these applications. In fact, Cinema 4D's R15 was just released (as of October 2nd, 2013).
Open-source Blender. I'm not even going to bother mentioning other options for now, as I have yet to find an option that beats it. There are plenty of projects out there done using Blender (Sintel is a perfect example of a short movie made entirely in Blender). It does everything you could possibly expect from it, along the lines of Cinema 4D and all of the other paid applications. Best of all, it's free and fully open-source.
Perhaps the best digital painting tool out there. Has the widest range of brushes, painting media, etc.
1) Krita - mentioned it already. One of the best free digital painting applications available. Has excellent support for Wacom tablets.
2) MyPaint - similar to Krita. Cross-platform.
3) Alchemy - more of a niche program. Great for random sketching, doesn't have an undo function.
4) Gimp Paint Studio - Set of tools integrated into Gimp to provide digital painting tools, brushes, etc.
Development Tools (IDEs)
Microsoft's Visual Studio is probably one of the most common proprietary options, with development environments for C, C++, C#, among many others. On the OS X side, there's Xcode for developing in Objective-C. This section will list some of the alternatives to using the paid programs.
1) Eclipse - In my humblest opinion, one of the best IDEs available. Free, completely open-source and extensible through plugins. I've personally set my installation of Eclipse to work with Python, C, C++, Java, Android, and PHP/MySQL, and that's barely scratching the surface of the amount of development environments that can be integrated into Eclipse through plugins.
2) Code::Blocks - Another open-source IDE primarily for C++, but has a plugin system to easily extend functionality. Cross-platform.
3) Netbeans - free and open-source, comes default with the Java Development Kit, as an optional addon. It does support development environments for multiple languages.
1) Programmer's Notepad - Supports syntax highlighting for multiple languages. Windows only.
2) Visual Studio Express - The free version of Visual Studio. It's perfect for people who want to get started developing on Windows. Naturally, Windows only.
1) Sublime Text - Technically paid, but a free, unlimited trial is available. It is cross-platform, and widely regarded as one of the best Text-based development environments.
2) IntelliJ - Specifically for Java and Android development.
This is a pretty unique category, as there are literally dozens of cloud-based IDEs for various languages. I'll try my best to highlight some of the best ones based on languages supported. Feel free to link me to any Cloud IDEs you know of and I will add it to the list.
1) Cloud9 - Code anywhere. Free and subscription available. Doesn't appear to have language restrictions.
2) Codenvy - Free and premium subscriptions available. There are free premium packages if you plan on developing open-source projects (the way I interpret it).
By far the best video recording and streaming tools available. However, there are more than a fair share of free and open-source options.
1) Open Broadcaster Software - capable of streaming to Justin.tv, Twitch.tv and other streaming sites. Optionally, it'll also record to the HDD using a range of compression settings. While it is open-source, a Linux version currently doesn't exist. There is plenty of interest in a Linux version.
2) GLC - The Linux FRAPS. GLC is a bit tricky to install, but is excellent on Linux. Needs to be built from source.
3) Yukon - Similar to GLC. Needs to be built from source.
4) SimpleScreenRecorder - Name is self-explanatory. Supports desktop and game recording, as well as streaming to Twitch.TV and other streaming services.
5) Twitch Streamer - A minimal shell script designed to stream directly to Twitch. Captures from the X server directly.
1) FFsplit - a free streaming software available primarily on Windows.
2) MSI Afterburner - one of the best free options for recording gameplay.
Everyone needs a media player, whether it's combined or just for music.
1) VLC - easily the best media player available. Also capable of recording the desktop and there's also the possibility of a video editor being added later on. Supports Bluray with some workarounds.
2) MPlayer/SMPlayer - along the lines of VLC. Cross-platform.
3) aTunes - iTunes equivalent on Windows and Linux.
4) Amarok - feature-rich media player.
5) XBMC - great open-source media player, capable of all types of media. Particularly good for an HTPC setup.
6) Audacious - open-source and available on many Linux distributions. Also cross-platform.
7) Clementine - cross-platform and open-source music player.
8) Plex - media streaming option along the lines of XBMC, but designed to run as a server. Ideal for a centralized media server and streaming to multiple devices (Mobile, PC, HTPC, etc).
9) Windows Media Player classic - plays a wide range of formats, specifically rmvb (RealPlayer). Simple and easy to use interface. A great alternative to VLC media player, but is Windows only despite being open-source.
10) Banshee - Open-source and cross-platform media player. Great replacement for iTunes (supports iPod syncing).
11) Apollo - A music player for Android. One of many options on Android.
12) MPV - Fork of mplayer2 and MPlayer, lightweight and easy to use.
1) Foobar2000 - IMO, one of the best and most configurable music players.
2) Winamp - This is only included because it's one of the more popular options. I personally would not recommend it, as it is more bloated compared to other options.
3) KMPlayer - Free media player on Windows.
4) iTunes - self-explanatory. Windows and OS X only, with alternatives above for Linux.
5) MusicBee - Free Music player available on Windows.
6) PotPlayer - Free music player for Windows operating systems.
This section is perhaps no longer needed due to SteamOS. However, for games that don't run natively on Linux (and ignoring Steam's in-house streaming option), here are the best ways to get games running on Linux:
1)WINE - The easiest way, supports a wide range of Windows applications and Games. Check the AppDB for specific issues with some applications. Generally, anything rated Gold and above in their database will run well.
2) PlayOnLinux - essentially WINE, but with a simple GUI to make managing Games easier. Also supports various Windows applications. A full list of supported software is on their website.
I know the topic says Free/Open-source, but I feel like this deserves an exception:
1) Crossover - basically a paid version of WINE with better support.
Stands for Computer Aided Design/Manufacturing/Engineering. Prime examples of proprietary software are: SolidWorks, Unigraphics NX, Catia, ANSYS, Pro Engineer, AutoCAD, among many more. The following is a list of free and open-source alternatives.
1) FreeCAD - the perfect AutoCAD and Solidworks replacement.
2) OpenFOAM - The best open-source alternative to ANSYS tools (primarily used for numerical simulation in Structural and Mechanical Engineering).
3) Scilab - excellent replacement for MATLAB (which is cross-platform, while still proprietary). Scilab is the free and open-source equivalent based on Python.
4) Octave - very similar to Scilab and MATLAB.
5) Scipy - a python extension specifically for scientific and simulation-based calculations.
6) CAElinux - Should really belong in a section of its own, as it's an entire distribution built around CAE.
The most common ones are BitTorrent and uTorrent, among others. Most of these clients are free, but aren't open-source. Some of them are more bloated than others. The following is a list of free and open-source clients.
1) Deluge - Great torrent client. I used it briefly; supports extra features through plugins. Cross-platform.
2) Transmission - Same as Deluge, free and open-source. Runs on many Linux distributions.
3) rtorrent - Generally installed through the repositories of whichever distribution. Terminal based, very simple yet powerful. Optionally, rutorrent can be installed to give it a web-based interface. These two are a very popular choice for a dedicated server running as a Torrent box (frequently referred to as a seedbox).
4) qBittorent - Cross-platform and open-source.
5) Tixati - Heard about this one more recently. Runs on Windows and Linux.
Instant Messaging/Chat programs
Not really a category that needs to be included, as most are free. However, not all are open-source. The only proprietary paid program I know of is mIRC, which is a commonly used IRC program. Some alternatives to mIRC:
1) Hexchat - an improvement over xChat. Cross platform (Windows, Linux) and open-source. Lots of features. xChat Aqua is an option for OS X.
2) Irssi/Weechat - minimalist IRC program. Not suited for everyone, but has a clean interface, and fun to tinker around with. Weechat is similar to Irssi.
3) Pidgin - mutli-protocol chat program. Supports IRC as well as many other common ones: Windows Live, Facebook, Jabber, Google Talk, AIM and many more.
4) Jitsi - similar to Pidgin, has some nice security features.
This section contains tools that run from within the Linux terminal, and don't exist as a standalone application. Nevertheless, they are quite powerful when used correctly.
1) Mozilla Thunderbird - probably one of the most well-known email clients. Cross-platform.
2) Claws Mail - An open-source email client for Linux. Cross-platform.
3) Mutt - Terminal-based email client.
4) Squirrel Mail - Personally used it to set up an Email server on a dedicated server (Kimsufi 2G), works wonderfully. Simple web interface for checking email.
Linux Terminal-based Tools
This section contains tools that run from within the Linux terminal, and don't exist as a standalone application. Nevertheless, they are quite powerful when used correctly.
1) Vi/Vim - excellent text editor for Linux. Comes pre-packaged with many Linux installers.
2) Nano - also comes pre-packed with Linux installers.
4) cmus - Terminal-based music player.
5) Mutt - Terminal-based email client.
Generally not a problem for Linux due to its security features; however, there are some open-source and free options available for Windows, OS X and Linux. I haven't used the open-source ones below, so I cannot comment on its effectiveness. Nevertheless, I'll list them for people to try out.
1) ClamAV - Available as source code for various Linux distributions.
1) Avast - free and pro versions available. One of the most recommended free options.
2) AVG - same as Avast. Personally find it to be a bit bloated.
3) Microsoft Security Essentials - comes built into Windows 8, available for Windows 7 as well as other Windows OS's.
4) Malwarebytes - Anti-malware software.
The following section contains software used to view and manipulate PDF files (annotations, editing PDFs, combining, etc).
1) PDFCreator - print to PDF, among other features.
2) Bullzip PDF - A printer driver which can be installed to print any document type as a PDF. Particularly useful for obscure file formats that can't be converted directly to PDF.
3) SumatraPDF - A free PDF and ebook (.epub, .mobi) reader.
4) Evince - A replacement PDF viewer that supports other file formats.
5) Xournal - free and open-source software specifically replacing OneNote or other Journal applications. Supports tablet PCs, and is able to annotate PDFs.
6) Stylus Labs - So far, of the Journal applications I've tried, this works the best in terms of writing performance. Xournal had an input lag that I noticed on Windows, not sure how it runs on Linux. Saves as .html files, with optional PDF export. Quite the quirky website design too.
7) PDFLite - PDF Viewer and printer (converts multiple formats to PDF). Source code is freely available for compiling on Linux.
This section contains software used for virtualization, whether it be development environments (virtual servers), or virtual machines. It's a fairly broad category. Some of the software under development tools were moved to this section to be a bit more accurate. The list includes free and open-source options.
1) Oracle's Virtualbox - the go-to option for free virtual machines. Supports a wide range of guest and host operating systems.
2) VMWare Workstation Player - available in Free and Pro versions (for commercial use).
3) Xen - Open-source virtualization, supports many guest operating systems and also supports various cloud platforms (OpenStack, etc).
4) KVM - another popular open-source virtualization program for Linux.
5) XAMPP - Web development environment.
6) Vagrant - creates a Virtual Server and sets it up as a development environment. Easily create and re-create (in any desired configuration) development environments to suit your needs.
7) WPN-XM - Web development environment built around Nginx (alternative web server to Apache), PHP, and Mariadb (faster alternative to MySQL).
This section contains mostly things that don't fall into the above categories, generally free. Some of them are cross-platform. Some of the summaries below may not be very accurate, so correct me if I'm mistaken. I've only used a couple of them in the past.
1) 7-zip - Everyone should have this, everyone should love it. Much better features compared to winzip and works with many different compression formats.
2) KeePass2 - encrypts and stores all of your passwords.
3) Xming - view/run X (Unix/Linux) based programs on Windows.
4) Cygwin/MinGW - Linux environment on Windows, can be used to compile programs from source on Windows. More involved, so usually ideal only for the tech savvy. Nice to have though, for people who want to tinker.
5) PuTTY - Simple SSH Client. Good for managing servers via command line.
6) Filezilla FTP - One of the best free FTP clients. Believe it also has SSH built in, but never used it.
7) Ghostscript/Ghostview - viewer/interpreter for Postscript, a programming language for creating vector graphics.
8) TrueCrypt - one of the best free disk encryption. Has automatic and real-time encryption of data.
I haven't personally used many of the above applications, but it's a starting point for people interested in making the jump to Linux or SteamOS. Some of these options are a bit more involved to get running, but don't be afraid to get your hands dirty! It's an immense learning experience, and well worth learning.
This indicates the modem is losing connectivity to the outside world along the DSL phone lines running from the modem through the house wiring, out to the telephone pole or pedestal box, or even further upstream along the lines going to the node serving your area. Contact your ISP and have them check for outages or drops on the node serving your neighborhood, and also have them run tests on the modem, if possible. They'll be able to see if multiple other houses in the area are impacted or if it's just your address, after which you can start narrowing down where the problem exists.
You would have to read the warranty terms that came with the machine to be certain. However, without knowing them and just going by what I would expect, you should be fine. They would have to be colossal asses to void it just because you changed some software. Any competent company and professional understands the very real distinction between hardware and software, and what "damage" to either entails for the other (ie, nothing).
I just ran down to the graphics department and found the model of the drives they use. I was surprised to find that they are just USB 2.0 drives:
None of the editors have any issues with performance using these drives. Read speed shouldn't be an issue in Quicktime for either drive since the playback is just sequential read and none of the files are especially high bitrate, unless mine is especially fragmented for whatever reason.
The Seagate drive I have is this: https://www.amazon.com/Seagate-Expansion-Desktop-External-STBV3000100/dp/B00834SJS0?th=1
I think I'm facing file corruption too though, I tried connecting the exFAT drive to my windows machine and it immediately prompted to repair the drive. My hope is that a different drive formatted in HFS+ will fix the issue, but until I can get a new copy of the files on a new drive I'm stuck, which is unfortunate for scheduling reasons.
Edit: Something is clearly wrong with this drive. I connected it to my Mac and opened a folder containing three files from a go pro. I tried to open one in quicktime and quicktime appeared in the dock but never actually opened, while finder was stuck with a spinning rainbow wheel. Eventually the drive disconnected itself and there is now a "drive not ejected properly" warning.
Edit 2: I ran a benchmark of the seagate drive on my windows machine and it has as sequential read of 174 MB/s and a sequential write of 183 MB/s, which is definitely faster than the USB 2.0 drives the other guys are using.
Fun fact, if thread is originally posted in section where post counter has been turned off (Off Topic and Forum Info), even after thread has been moved, posts in it aren't counted towards post count. Only ones posted after the move are.
