I have several thecus NASes (http://www.thecus.com/) the N5200, the N5200Pro and I'm looking into a N7700 or a N8800. They all have Gigabit ethernet connections. They are more expensive than purpose built boxes - but they are "set it and forget it" appliances - which is where there value comes from.
I can sustain approx 25MB/s write and 40 MB/s on my N5200. NOTE: That's bytes not bits. In otherwords 200Mbit read throughput and 320Mbit write throughput. This is far better than the other domestic of SOHO NASes - which is why thecus tends to win awards http://www.thecus.com/news_contentx.php?nid=827 , http://www.tomshardware.com/reviews/holiday-gift-guide,2065-12.html
If you contrast this with one of my windows RAID arrays (100+MB/s read 100/MB write - array to array or just streaming) it looks rather poor.
If you want something that you can just forget about and will give reasonable performance then TheCus is what you want... if you want better performance than a custom built server is what you want (Windows or Linux).

# Enhydra Shark Shark is completely based on standards from WfMC and OMG using XPDL as its native workflow definition format. Storage of processes and activities is done using Enhydra DODS.
# Codehaus Werkflow Werkflow is a flexible, extensible process- and state-based workflow engine. It aims to satisfy a myriad of possible workflow scenarios, from enterprise-scale business processes to small-scale user-interaction processes. Using a pluggable and layered architecture, workflows with varying semantics can easily be accomodated.
# OpenSymphony OSWorkflow What makes OSWorkflow different is that it is extremely flexible.
# jBpm jBpm is a flexible, extensible workflow management system. Business processes , expressed in a simple and powerfull language and packaged in process archives, serve as input for the jBpm runtime server. jBpm combines easy development of workflow-applications with excellent enterprise application integration (EAI) capabilities. jBpm includes a web-application and a scheduler. jBpm is a scalable J2EE application.
# wfmOpen WfMOpen is a J2EE based implementation of a workflow facility (workflow engine) as proposed by the Workflow Management Coalition (WfMC) and the Object Management Group (OMG). Workflows are specified using WfMC's XML Process Definition Language (XPDL) with some extensions.
# OFBiz Workflow Engine The Open for Business Workflow Engine is based on the WfMC and OMG spec. OFBiz Workflow Engine uses XPDL as its process definition language.
# ObjectWeb Bonita Bonita is a flexible cooperative workflow system, compliant to WfMC specifications. A comprehensive set of integrated graphical tools for performing different kind of actions such as process conception, definition, instanciation, control of processes, and interaction with the users and external applications. 100% browser-based environment with Web Services integration that uses SOAP and XML Data binding technologies in order to encapsulate existing workflow business methods and publish them as a J2EE-based web services. A Third Generation Worflow engine based in the activity anticipation model.

# Open Business Engine Open Business Engine is an open source Java workflow engine which supports the Workflow Management Coalition's (WfMC) workflow specifications, including interface 1, also known as XPDL, interface 2/3 known as WAPI and interface 5 for auditing. OBE provides an environment for executing activities in a controlled, centralized environment. OBE supports both synchronous and asynchronous execution of workflows. The primary OBE implementation is based on J2EE.

I have been using MySQL's eventum http://dev.mysql.com/downloads/other/eventum/featu res.html/ for the past few months and have found it very good.
It's PHP MySQL based. It supports multiple projects, email integration, supports public/private fields, custom categories, custom fields, project management (time tracking), issue listing, sorting, searching, reporting and graphical stats. It also supports SOAP (remote posting) and RSS for viewing
OS's run on hardware. Hardware detecticion is hard
on
OS Independent Games?
·
· Score: 1
This was discussed on slashdot a little while ago. The short version is that OSes ultimately run on some sort of hardware. Up-to-date hardware detection and utilisation is hard to do and in the real world only big companies like MS have the resources and $$ to make sure that every little graphics card, audio card, input device, network card etc work as promised for everyone.
Yes, most hardware works most of the time on Linux but it doesn't have anywhere near the coverage as windows. Hence windows provides a much better foundation upon which to build a game. Apart from that configuring windows is still far easier for the average user to do (if/when it doesn't work).
Building a bootable game out of linux would still fall prey to the hardware detection routines and abstraction.
Games traditionally push hardware and software right to the very bleeding edge... and at those points linux is just not as good as windows to base a game on.
I'm currently undergoing treatment for RSI of the wrists/fingers. I have similar experience (20 yrs at the keyboard) and like you I was concerned about the stigma so I am paying for treatment myself.
I have found Oesteopath's to be far more knowledgeable about this than your local doctor. A good article I found is here http://www.rsiprogram.com/articles%5CLeadArticle.h tm
An oesteopath will most likely tell you that you are pinching nerves in your forearm and neck/shoulder area. I've had treatment for a month now and I am no longer experiencing pain when I type but complete recovery usually takes 6+ months... which is a while but certainly better than losing the use of your hands/keyboard
I have taken some remedial actions such as reorganising my desktop, putting the keyboard on my lap (takes weight off shoulders) and using an ergonomic Vertical mouse (http://www.rsiprogram.com/equipment/verticalMouse.htm) as well as a gel wrist rest.
Good luck with your treatment.
I have to agree 100% with the notion of using Engineers as scientific programmers - as that is exactly how I started out programming. I started at the CSIRO (a scientific industrial research organisation ) in Australia. They interviewed many comp-sci grads and found them all lacking in the basic grounding necessary - hence they moved on to the engineers - they hired myself and a couple of other engineers over the coming years.
I found, in my experience with the CSIRO, that the job wasn't just involved with programming but required me to go the next level and actually get involved in the research. In order to achieve that I needed knowledge outside that which would normally be encountered in a standard comp-sci course ie chemistry, physics, maths, numerical modelling/analysis, stress analysis and the odd bit of management and report writing. Since then I have completed my Bachelor of Engineering and a separate Bachelor of Computer Science. From that I can say I was unimpressed with the range of material presented to comp sci students. There often is too much focus on a particular set of languages rather than a good broad problem solving background and grounding in basic science and knowledge. Just how much time do any of you actually spend in simply coding - I'd bet not all that much if you are doing it right:-)
So look for the engineers to solve your problems, even more than Comp sci students they are trained to solve problems, analyse and think through solutions. Since then I have found that employers have liked most my broad scientific training over my comp sci experience. No disrespect meant to anyone with only a comp sci degree but in my experience I have found that the best programmers / software engineers have been those that have a broader background eg Physicists, Engineers, Mathematicians and the like who also have comp sci degrees or significant experience in the field.
