Are the projectors connected with vga? We found some problems with dvds were fixed by installing the correct drivers. Sometimes we had to resort to windows vista or xp drivers.

We are looking for a new technician to work in a busy IT support department. The school is a secondary girls school and has a mixed sixth form. The school has a really nice atmosphere with friendly staff and students. Technology wise, we have nearly finished upgrading to windows 7. We are running most of our servers virtually with vmware vsphere. We also have a ruckus wifi system in place. For system imaging and software deployment we are using Altiris Deployment solution. We also have about 50-60 interactive whiteboards (mostly promethean) and projectors, several Lapsafe laptop trolleys, many HP printers, visualisers and other typical kit found in schools. Experience with any of these would be a bonus. If you have any questions please feel free to contact me and I'll do my best to help. --- 36 hours per week Grade D £17,808 - £20,205 depending on experience Closing Date: 12noon 20th September 2012 Coombe Girls' School is a Leading Edge Language Specialist School. There are approximately 600-700 computers across the network including desktops, wireless laptops and servers. Applicants should have a skill level at least equivalent to CompTIA A+ and be familiar with Windows xp/7, MS Server 2003/2008, and Mac OSX. Experience of supporting Microsoft SQL databases and SharePoint platforms would also be desirable, in particular SIMS.net and SIMS Learning Gateway. The appointed person will report to the Network Manager and will be part of a team with two other technicians. Vacancies | Coombe Girls' School

We have a few of these on our network. They seem pretty rock solid. They don't have 10g ports as mentioned.

Its been known to happen. We have similar decisions to make with our projectors. I'm rarely sure what the right choice is. I usually look at the age of the projector, its original brightness and condition etc, and make a best guess. I think your options are: 1. Try a bulb from an identical projector and test it. 2. Buy a bulb and take a chance 3. Pay someone to fix it/test it. 4. Replace it. The casio projectors (like the Xj-A241) and similar look like good replacements, as there is no bulb or filters to mess with. It might be a good idea to discuss with your line manager and see what they think. Edit: Just another thought, have you checked the bulb hours/lamp-life? Some projectors refuse to turn on if the lamp goes above a certain number of hours. If this wasn't reset when the bulb was changed, it could cause symptoms like this. I think on most sanyos, there is a reset button near the input connectors.

Sounds like a bulb issue. You can't check most projector bulbs with a multimeter because they don't have a filament. You can usually tell a good bulb from a blown one by looking at it. The insides blow up like a balloon, and get coated with mercury so will look dark grey. A good bulb looks clearer and cleaner than a dead one. How long since the bulb was last changed?

Quality and management features are as important as raw speed in my opinion. And the structure of your current network as has already been said. There is little point in having a really fast and really cheap switch if it goes down regularly.

We got a batch from viglen last term with ssds. I think the price was reasonable. We may have had to ask for customised systems rather than the standard ones. You might need to talk to an account manager rather than ordering direct from a website. I didn't do the order myself, so Im not sure of the exact details.

I've looked at it briefly, but by the time its kitted out with PSUs and switch modules, it seems like quite a large sum of money.

I'm in a similar position to the OP. I've been wondering why the 5406 and 5412 switches are more popular than stacked switches? I'm thinking that a stacked core would give us better redundancy than a chassis. I'm a bit worried about having a single management module and chassis as a single point of failure. I hope I don't sound like i'm second guessing anyone else's choices, I'm just trying to figure out what's best for my school. How do people find the 54xx series in terms of reliability?

Might be an m5 thread. You could try a hardware store, maybe b&q, wickes or similar. Normal rack bolts in the uk are m6 i think, m5 should be about 1mm thinner. Wilkinson's might be worth a look as well, although their range isn't as wide.

I think you may have missed a step. Did you read through the bit after the code? if not, follow that bit and it should work. I think the specific bit that needs to be done is under 'Basic Settings' for the website, click on 'Connect As' and choose application user. Internally, mrbs calls a php function called get_current_user() which returns the username of the user who is running the mrbs php script. Normally this would be the user account that is setup when you install iis - this something like the servername followed by the dollar symbol. When you enable the Connect as application user option, the script is run by the user who is logged in to to the client.

Welcome to Classic Shell gives you something like the old startmenu. You can even set it to open metro when you click on the icon.

If they are on a windows client with IE on the same domain, they should automatically log in. Otherwise they should get a login box where they can login with their own domain username. Without changing any other options, they will be able to delete/change their own bookings, but not anyone elses. Admins will have full control. So it should work the same as with ldap authentication. You can check this, if you make a booking as a normal user, and then look at the booking details, the username should show up under 'created by'.

are you using windows authentication (single sign on) or just ldap? I've got windows authentication working with the following in my config.inc.php: $auth["session"] = "nt"; // How to get and keep the user ID. One of // "http" "php" "cookie" "ip" "host" "nt" "omni" // "remote_user" $auth["type"] = "none"; // How to validate the user/password. One of "none" // "config" "db" "db_ext" "pop3" "imap" "ldap" "nis" // "nw" "ext". // The list of administrators (can modify other peoples settings). // // This list is not needed when using the 'db' authentication scheme EXCEPT // when upgrading from a pre-MRBS 1.4.2 system that used db authentication. // Pre-1.4.2 the 'db' authentication scheme did need this list. When running // edit_users.php for the first time in a 1.4.2 system or later, with an existing // users list in the database, the system will automatically add a field to // the table for access rights and give admin rights to those users in the database // for whom admin rights are defined here. After that this list is ignored. unset($auth["admin"]); // Include this when copying to config.inc.php $auth["admin"][] = "127.0.0.1"; // localhost IP address. Useful with IP sessions. $auth["admin"][] = "administrator"; // A user name from the user list. Useful // with most other session schemes. $auth["admin"][] = "windows-admin-username"; Then under the iis manager, you need to configure authentication for the website. You need to enable windows authentication, and disable the others. then edit the providers for windows authentication and make sure NTLM is at the top. Finally, under 'Basic Settings' for the website, click on 'Connect As' and choose application user. You probably want to restart iis at this point. You can configure who has access in the iis console, and you grant a user admin rights by adding a $auth["admin"][] = "windows-admin-username"; line to config.inc.php after the other ones. replace windows-admin-username with the users domain account name.

Maybe a resistance decade box?

Github is a bit simpler and has a nicer interface (imho). Sourceforge has more features, for example different types of version control systems. Also, you don't seem to get a mailing list with github. You might find you have problems with proxies with some version control systems - git and svn took a bit of effort to set up. Otherwise, both offer a pretty reliable service, just make sure you keep your own backups.

I think it depends a lot on the course. For teaching a full course on video editing or media studies it probably makes sense to use final cut or adobe premier. If your doing a module that's a couple of weeks long, then you may not have the time to teach a full video editing package. It might be that the project is to produce a video about a topic and not be about learning video editing. Also, in a busy school the teachers may not have time to learn new software. Its all about having the right tools for the job. Given good source footage, I think you can get some pretty good results with serif. And frankly, Windows Movie Maker can't die soon enough.

I ordered from RS mid june and got a 6 week estimate. I had ordered after my allocated week, so I think it was put to the end of the list. I managed to damage my first one (from farnell), and break both the usb ports and the network ports. The desktop was quite slow, but I found it usable. As you say, when they get hardware rendering working properly it should be much better. I've had audacity and other programs running, and they've shown quake 3 running as well. I've managed to make sip phone calls using linphone. So the device itself is fairly powerful.

I found with traceroute that the default type of scan didn't work on either windows or linux. I don't know what method it uses, but on linux there is an option to scan with tcp or icmp, both of which worked. The documentation was unspecific on the default method, however, it only returned hostnames for the first two hops which are on our network. My windows 7 workstation is on the same subnet as the servers, so thats not an issue. I think you can use network monitor on xp, if not, you can use wireshark. I've not really used network monitor, wireshark is my tool of choice for this. Once you've done a capture, you need to look for packets relating to videocentral/whatever is the problem. Once you stop the packet capture, you should get a long list of packets that have been captured. There should be search and filter options in both wireshark and network monitor, but I don't know how useful they will be unless you know exactly what you are looking for. You might end up filtering out what you need to find. Its well worth having a play around with one of these tools, and getting familiar with it. I haven't had any reported problems since this happened originally, so I think whatever the problem was has resolved itself for us. It may well be that we have two different problems, but it sounded suspiciously similar.

Tried a tracert from a linux box. It seems a traceroute from windows doesn't work very well on LGFL outside of the school network. Even from linux, it didn't show up anything particulary helpful, but then we don't seem to be having the issue at this point. The log is below It looks like its a specific problem with streaming media. Everything else loads up fine - except fronter, but thats always slow. I don't think this is a routing issue, it looks more like filtering or firewall problems. # traceroute -T videocentral.lgfl.org.uk traceroute to videocentral.lgfl.org.uk (82.2.159.101), 30 hops max, 40 byte packets 1 our_core_switch (internal_ip) 1.698 ms 2.587 ms 9.577 ms 2 LA_Router (router_ip) 0.410 ms 0.812 ms 0.953 ms 3 * * * 4 10.1.4.2 (10.1.4.2) 0.738 ms 1.219 ms 1.158 ms 5 212.85.18.1 (212.85.18.1) 2.270 ms 2.606 ms 2.622 ms 6 172.31.253.22 (172.31.253.22) 2.568 ms 2.498 ms 2.309 ms 7 * * * 8 213.152.245.54 (213.152.245.54) 8.067 ms 8.008 ms 8.992 ms 9 brnt-bb-1b-as2-0.network.virginmedia.net (213.105.175.26) 12.970 ms 12.539 ms 11.426 ms 10 brnt-bb-1a-ae0-0.network.virginmedia.net (213.105.174.225) 11.446 ms 11.319 ms 11.340 ms 11 brnt-core-2a-ae0-0.network.virginmedia.net (62.253.174.54) 8.884 ms 8.824 ms 8.763 ms 12 brnt-lam-5-tenge74.network.virginmedia.net (213.104.146.110) 9.470 ms brnt-lam-5-tenge71.network.virginmedia.net (195.182.172.30) 9.408 ms brnt-lam-5-tenge74.network.virginmedia.net (213.104.146.110) 9.348 ms 13 brnt-lam-5-tenge73-1845.network.virginmedia.net (213.104.145.22) 11.366 ms 11.303 ms 11.276 ms 14 201-141-168-194.static.virginmedia.com (194.168.141.201) 10.494 ms 80.2.158.201 (80.2.158.201) 11.656 ms 82.2.159.201 (82.2.159.201) 10.789 ms 15 * * * 16 * * * 17 82.2.159.101 (82.2.159.101) 12.276 ms 12.401 ms 11.731 ms

We've had similar but intermittent problems with you tube and BBC iplayer the past 2 days. Not had much luck tracking it down. We didn't think to try video central. I might try that tomorrow if it comes up again. No idea for a fix or troubleshooting im afraid. We're in Kingston, and using lgfl via kingsnet. Our partner school didn't seem to be having the same issues.

I'm using something very similar to this with my raspberry pi http://www.ebay.co.uk/itm/1080P-HDMI-Male-VGA-Female-Video-Converter-Adapter-Cable-PC-DVD-HDTV-New-/170850801393. It seems to work, even though everything Ive read says it shouldn't. Not sure if it helps with your problem. It didnt work with my set top box, but does seem to work with my xbox 360.

I would agree that the developer should be doing the leg work here, especially if money has been paid. You could maybe try the developer tools in google chrome. The network tab might show which bit is slow. Also you could try mysql workbench, I think that has some monitoring stuff in it. The windows resource monitor on the server may also show up something useful. Do any other sites on this server use mysql or php? How many users are connecting at once?

I doubt they would be able to do much damage with network stuff. I would be more concerned with running other programs, using the subprocess module or the os module. But this is common to most, if not all, other serious programming languages. It probably depends on your staff and students as to how much you need to secure it. In terms of security, python and vb have fairly similar security issues. I'm also waiting on my pi.

Python is like any other windows program. It has to obey ntfs permissions. The only problems are if the permissions arn't set properly, or when code is submitted to a teacher. If a teacher (or admin) runs a students program, then it will run with the teachers permissions. Practically I don't think there is much chance of this being a problem, but the risk is there. The best solution to that is if the member of staff reads the code before running it. most stuff should be obvious.
