  • What Sort of Server Setup Am I Likely to Need? - School A/V streaming

    - by DeathMagus
    My prior experience with servers has generally been limited to home file-sharing servers, low-traffic web-servers, and the like. This leaves me with the technical knowledge of how to set up a system, but little experience in terms of scaling said system. My current project, however, has me as the technical lead in setting up a school for online audio and video streaming. The difficulty I'm running into is that I don't quite have the experience to guess what they'll need, and they don't have the experience to tell me - so I've tried to ask as many pertinent questions about what they want to do with their server, and here's what I found out: About 1000 simultaneous users, and hoping to expand (possibly significantly) Both video and audio streaming, at obviously the highest quality possible Support for both live and playlist-based streaming. Probably only one channel, but as it's an educational opportunity, I imagine letting them have a few more wouldn't hurt. No word on whether they're locked into Windows or whether Linux is acceptable. Approximate budget - $7000. It may actually be about $2k less than this, because of a mishap with another technology firm (they ordered a $7000 DV tape deck for some reason, and now the company wants them to pay a 30% restocking fee). The tentative decisions I've already made: I'm planning on using Icecast 2 for my streaming server, fed by VLC Shoutcast encoding. Since the school already has a DMZ set up, I plan on placing the Icecast server in there, and feeding it through their intranet from a simple workstation computer in their studios. This system isn't in any way mission critical - it's an education tool (they're a media magnet school), so I figure redundancy is not worthwhile to them from a cost:benefit perspective. What I don't know is this: How powerful of a server will I need? What is likely to be my major throttle - bandwidth? How can I mitigate that? Will I need anything special for the encoding workstation other than professional video and audio capture cards and a copy of VLC? Are there any other considerations that I'm simply missing? Thanks a lot for any help - if there's more information you need, let me know and I'll tell you all I can.

  • What happens in case of utility power failure?

    - by Jake
    (in the office) Today, the UPS battery replace warning light lit up and there was a slight panic as the all the technical people will not be around the next few days. But after thinking a bit further, I realise that in case of power failure, no client computers will be able to turn on in the first place and operations will be disrupted regardless of whether the UPS keeps the server up. This makes me wonder if the UPS is really such a critical component? What do you think?

  • I need a tutorial for IIS/ASP.Net administration

    - by TheCodeMonk
    My technical support staff is only a little familiar with IIS and that's only as far as install goes. They need to install/update and configure ASP.Net web applications and WCF services that we write. Does anyone know any good tutorials/books/web sites that can help them understand some of the basic concepts of web applications and maintaining them on IIS?

  • Malware vs Viruses

    - by Kyle Brandt
    Is there a legitimate technical difference between malware and viruses? I have looked at the Wikipedia entries but I am not really seeing the difference. Currently, I kind of feel like this is just Symantec's way of getting more money for products (features). But maybe someone involved more deeply in this area can explain this.

  • Word caption style

    - by Theodor
    This should be a common problem for anyone involved in technical writing. When you insert an image (or table etc.) caption in Word, you get this dialog. You enter your caption, in this case "A happy bicycle" (in yellow). This might be fine for a happy bicycle, but I want to have captions that have one style for the "enumeration" and one style for the description, as such: I have tried searching for this but I haven't found anything yet...

  • On-call EC2 System Administrator

    - by Ball
    Is there a company that can respond to critical alerts for our EC2-based web application? Does such a service exist? If not, is there a place where we can find individuals who are willing to do 5-10 hrs of work a month responding to issues? Thanks. I know this is not a technical question, but I know it's a useful question for many companies and I'm not sure where else to ask.

  • Advice on Auditing VPN Connections

    - by WhiteAdam
    I've inherited a network that is truly a mess and the VPN config is amazingly long with confusing group names and very little documentation. I am curious to see how others have gone about auditing these types of connections. Are there any forms out there? What information should I collect? I assume things like Customer, Department, Technical Lead, and etc. Thanks in advance for any advice on this nightmare.

  • 403 error with codeignitor

    - by DJB
    When I type in the standard web address for my site, I get a 403 error. However, when I type in a more exact address, say pointing to an index.php file, everything shows up fine. I'm using Anodyne Productions' Nova (SMS 3) which uses codeignitor. All accompanying software (PHP/MySQL) is compatible. I'm not a very technical person, so I'm hoping that this is an easy fix. Thanks for taking the time to answer.

  • Does frequently formatting and reinstalling an operating system damage a hard drive?

    - by Closure Cowboy
    I tend to format and reinstall my operating system fairly frequently (about once a month). I apologize for my lack of technical terms, but I do not perform a "full format" (the type of formatting that zeros-out the existing data). Regardless, I know that most modern operating systems consume several GBs of data. Is doing this particular damaging to my hard drives? Would it matter whether I'm using a solid state drive (I'm not)?

  • Tools for reformatting a spreadsheet into PDF?

    - by Todd
    I'm looking for an easy way to produce nicely formatted PDF documents using a subset of data available in a spreadsheet. Ideally, I would be able to produce one or more PDF documents for each row int e spreadsheet. Each row contains scientific data about a sample. There are numbers, text and images in the Spreadsheet that need to be reformatted in a nice way in a PDF. Ideally, the solution would be a piece of software that a non-technical but highly intelligent scientist could operate.

  • Windows 7 Home Premium or better on a Netbook?

    - by Michael Stum
    I have a Netbook with Windows XP Home. Processor is an Atom N280 (1.66 GHz) with 2 GB of RAM. I noticed that newer Netbooks come with Windows 7, but as Starter Edition (which kinda sucks). I wonder if there is a technical reason for using Windows 7 Starter? Or would a better edition (x86) perform equally well? I'm currently considering Home Premium, but BitLocker and Offline Files might have me get Ultimate.

  • What is a good operating system for relative newbies for setting up a website and source control? [on hold]

    - by Zeroth
    I'm part of a small group of people working on video games. We want to set up our own boxes to serve the website and handle the source control for development work. I have the most technical expertise, but its been a few years since I've set up or played with Linux or other open source operating systems. So I'm a bit out of the loop on what are the user-friendly open source operating systems out there right now?

  • SQLAuthority News – Uncut and Unedited Video Interview of Pinal Dave

    - by pinaldave
    Earlier this year Lohith (@kashyapa) from Bangalore took my ‘Uncut and Unedited’ video interview. It was really fun to answer his questions as it was very different from regular interview. He asked few personal details few technical details and made me show few secrets. I think if you want to see me Uncut and Unedited I urge you to watch the video. He has previously interviewed few celebrities as well. I think I am the only one in the list who is not celebrity.

  • Identifying Data Model Changes Between EBS 12.1.3 and Prior EBS Releases

    - by Steven Chan
    The EBS 12.1.3 Release Content Document (RCD, Note 561580.1) summarizes the latest functional and technology stack-related updates in a specific release.  The E-Business Suite Electronic Technical Reference Manual (eTRM) summarizes the database objects in a specific EBS release.  Those are useful references, but sometimes you need to find out which database objects have changed between one EBS release and another.  This kind of information about the differences or deltas between two releases is useful if you have customized or extended your EBS instance and plan to upgrade to EBS 12.1.3. Where can you find that information?Answering that question has just gotten a lot easier.  You can now use a new EBS Data Model Comparison Report tool:EBS Data Model Comparison Report Overview (Note 1290886.1)This new tool lists the database object definition changes between the following source and target EBS releases:EBS 11.5.10.2 and EBS 12.1.3EBS 12.0.4 and EBS 12.1.3EBS 12.1.1 and EBS 12.1.3EBS 12.1.2 and EBS 12.1.3For example, here's part of the report comparing Bill of Materials changes between 11.5.10.2 and 12.1.3:
