A phono turntable pre amp will likly have RIAA equalisation on it, so low frequencys will be louder than quiet ones. Maplins sell this Universal Preamplifier Module : Audio Modules : Maplin Electronics or Low-Noise Stereo Preamp Kit : TR Kits : Maplin Electronics, and there are some others on ebay. Don't know how good they will be. But as others have said, removing any volume limit on the ipod would be the best option. Note you would need 2 of the first one for stereo.

I think its doing authentication. See page 26 and 27 of this http://pjlink.jbmia.or.jp/english/data/PJLink%20Specifications100.pdf It looks like you take the random number from the end of the pjlink 1 line, combine it with a password (possibly set in the projectors menu?), and then do an md5sum, which is sent back to the projector with the command. The first random number changes each connection (or should do). eg: 8a9b46ba + password (8a9b46bapassword) becomes d7c143db41c6057c3d8c8d47b0a36140 I think the projector transmits PJLINK 0 if the authentication is disabled, or no password is set, the commands can then be sent without any code before them, ie: %1POWR 0 It looks like there is a perl module for this, google Net-PJLink

Do you need to add an exception for this server? Is the 2008 R2 server inside your network?

I don't think the first is possible by default. You could probably modify the php code to do it. I think it would need to go in edit_entry.php. Look at the part where it outputs the select box for this. How are you defining the user types? IIRC, mrbs only has admin and user, but you might be able to do some sort of regular expression or pattern matching if you have students starting with a different prefix (ie st01anon or c11anon), you could probably code that in. There are various options to restrict user bookings, if you look through systemdefaults.inc.php or areadefaults.inc.php (but that might not be in your version), you might find something that does the job. this bit seems similar to what you want: 219 /****************** 220 * Booking policies 221 ******************/ 222 223 // Most booking policies can be configured on a per-area basis, so these variables 224 // appear in the areadefaults.inc.php file. 225 226 // The settings below are global policy settings 227 228 // Set a maximum duration for bookings 229 $max_duration_enabled = FALSE; // Set to TRUE if you want to enforce a maximum duration 230 $max_duration_secs = 60*60*2; // (seconds) - when using "times" 231 $max_duration_periods = 2; // (periods) - when using "periods" Any settings that you change need to go in config.inc.php, or they get overwritten the next time you upgrade.

Its quite easy, its mostly web based. You install the sever software on a windows computer (old pc, server, whatever). It shouldn't take very long to get it up and running, although you might need to do more tweeking later to get it how you want it. If you want to use the inventory, then you tell it your ip range. You can get more detailed info if you tell it snmp names, and login accounts for your pcs and macs. It can then tell you if servers are offline, printers are out of toner, what software is on what computer. Its useful if you want to find out the differences between two pcs, or which computers are running an old version of office etc. I think ours only took about 1/2 an hour for the basic set up.

If the rcds are tripping (rather than circuit breakers), then it isn't just current, it will be the number of devices as well. RCDs detect an imbalance between the current flowing in the live and neutral wires. Each device will have a small earth leakage, which isn't a problem on its own, but if you add 32+ computers/laptops/servers onto one rcd, the cumulative imbalance will trip the breaker. The advice above about adding up the current is correct. If you are in any doubt, get someone qualified in to check it over. Messing up mains electrics could cause a fire which would be much more expensive getting an electrician in. You need to get a properly qualified electrician in to look at this circuit. Adding a ups will make things worse at this stage, as it will increase the electrical load and earth leakage, although your servers probably should be on one anyway. You should probably get your servers on their own dedicated circuit that isn't used for anything else, not hoovers, not laptop trolleys, not anything.

Is it possible for you to update to the latest version? 1.4.1 is 2 years old. There is an option in 1.4.7 for this: // Set a maximum duration for bookings $max_duration_enabled = FALSE; // Set to TRUE if you want to enforce a maximum duration $max_duration_secs = 60*60*2; // (seconds) - when using "times" $max_duration_periods = 2; // (periods) - when using "periods" There are also other improvments as well. If you don't have any customisations, the upgrade is usually fairly painless as long as you have a working backup.

If you don't ask, you don't get. If they did a separate vm licence for esx or xen, they could charge more and have keep the same amount of profit. OSX server used to cost quite a lot on its own. Having looked at the mac "server" mini, its rubbish - having a redundant hd doesn't make it server grade. It doesn't have much in the way of ventilation, and generally seems low quality to me, especially given the price. Also VDI and server virtualisation arn't quite the same thing. You can have other benefits with virtualisation like reduced electricity bills, hardware redundancy etc. Like you say, you don't really want to do video editing etc with VDI. The cost of a mac server is quite high if I just want to use MCX and workgroup manager, it really doesn't warrant its own physical box. Given the utter failure I had with it last week, I probably won't bother trying it anytime soon. I'd quite like to know if they even tested the ad integration before they released it first time round. Anyway, I think this might be OT now.

I've seen similar guides to those, but they all assume that you upgraded to lion from the app store. Our macs were pre-installed, and I couldn't find the dmgs they talks about. By this point, I had spent far to long messing around with these macs, and had lots more important stuff to do.

I had a very similar problem with our two new imacs. Too many problems with AD and an old mac server. Our support company seems to think downgrading was ok. I installed 10.6 (snow leopard retail edition) on a virtualbox pc on my imac, updated it to 10.6.8, then used carbon copy cloner to clone to a sparse image file. This was then copied to the c$ share on my main pc. On the new macs, I repartitioned the HD with the disk utility so we didn't lose 10.7 completely (no install disks for it, just a recovery partition). Then connected to the c$ share, install CCC and clone it back to the new partition. Finally, change the startup disk in the appropriate preference pane, and copy the various iLife apps (Garageband, iMovie, iPhoto) to the new disk, and run each one so it re-downloads all the content and libraries etc. After that, just set it up as normal... Time will tell how well it works as they've just gone out to our media department today.

* Whats happening with 10.7 and active directory? When will it work? * Can they make it so we can install osx server virtually on non-mac hardware? (I mean legitimately, not just technically)

You might want to change your admin password... In someplaces, mrbs passes returl=http://whatever.com/lastpage.php/ or similar to return the user to the previous page after its done something like deleting an entry. Your two choices are to rewrite the bits of mrbs to work differently (and that relys on your isp not filtering on "http", you might be able to change it to returl1=http://...), or to find another isp. If your booking system doesn't need to be available on the public internet, then you can host it fairly easily on a windows or linux server. However, It strikes me that something else might be going wrong as well as the isp block. the page returned by del_entry.php doesn't like the stock one, have you made any customisations to it?

MRBS does 2 and 3. I think 1 might be possible with the sims command line reporter, but I've haven't had a chance to try it yet. There is a thread on these forums if you search for it. You can set up mrbs to authenticate in several ways, using accounts stored on the config file, in the database, on active directory, or on an imap/smtp mail server. If you use iis on a windows server with windows clients, you can get single-sign-on working fairly easily. There is a good document included with mrbs when you download it that should tell you how to do the mrbs side of things. If you want to block staff from making changes, thats possible too. You can also set new bookings to require confirmation if you want, or limit how far in advance people can make bookings. Its got some really useful options in the current and next version. Periods can be setup in the config file. This is one of the main reasons we choose mrbs. Periods need to be well planned before deploying mrbs to users, as changes can be tricky once bookings have been made - its not impossible though if you know your sql. I've found the support for mrbs to be excellent - probably the best I've dealt with, commercially or otherwise. The developers are very helpful, and there are quite a few users on this forum.

What version are you using? Its blocked here. For recent versions of mrbs, the defaults are stored in a file called systemdefaults.inc.php. To change one of these settings, copy it into the config.inc.php file, and change it there. Some settings for areas only change the default for new areas, not for existing ones. These can be changed on mrbs under the area. You can change the user-visible text in the lang.en file (or the appropriate one for your language). Its probaly a good idea to make a note of any changes for when you come to upgrade in the future Can I suggest a good read through of the Authentication file included with mrbs. It documents all typical configurations for authentication. My guess is you are using the built-in user accounts in config.inc.php/systemdefaults.inc.php and are missing the unset() line. If the authentication file doesn't help, please let us know what your config is.

These ones aren't too bad. I usually do a silent local install using altiris. The exe file accepts the silent option (EA_MATH_12_SP.EXE /silent). You need to install it normally to start with so it can generate the license file. This gets written to the windows directory and needs to be copied to the windows folder on each client: C:\windows\exampro32.ini. If you use any other exam wizard or testbase titles, you can merge the different exampro32.ini files together.

Drivers would be my first guess. Try comparing the driver version on the ones that work and the ones that don't. You might find you need an older one instead of a newer one. The windows event log sometimes gives out useful info about whats failing. What authentication are you using and what windows version? We find 7 handles wifi much better than xp does. We've had some problems with the n210+'s from samsung (the n210's works well, don't know what they did to the plus but I wish they hadn't). I think I fixed it eventually by un-joining it from the domain, deleting the ad account, and starting from scratch. Ruckus does manage the channels itself. Its possible if there are lots of other access points around that the only option was to have 2 on the same channel. I think ruckus is supposed to do beam-forming, My understanding is that it adjusts the power sent in each direction. This should decrease the interference between neighboring aps. have you checked for any dead-spots where the netbooks are used?

Are you using a vga splitter, or is the pc monitor daisy chained off the projector? Also, how long is the vga cable to the projector, does it run past anything else electrical?

I tried it many years ago. It was really good for learning how linux works under the hood, but if you just want to try linux, then go for ubuntu/fedora or or something similar. Compiling some parts of it (like the kernel and X windows) takes a long time, and will take longer on a slower computer. It should work fine on a vm, but might be faster if you can do it on a decent pc. If you want any applications to run on it, you need to compile those as well.

I've had a few Sanyos like this this term that I fixed by turning them off at the wall and then back on again. Some of these projectors have two modes for the remote (if you want to operate two similar projectors in the same room). The manual shows you how to change the mode. Other options could be dead bulb, the lamp hours counter being over the limit, the thermal cutout having tripped (search these forums for the reset procedure), or it being properly broken and needing repair or replacement. If I remember correctly, there are also some reset buttons near the video inputs on the back. Might be worth trying those. Bear in mind if you run the bulbs for longer than 2000 hours, you risk the lamp exploding which can be difficult to clean out. The lamp should be clear and shiny inside when new. If its dull grey or the stem in the middle is blown up like a balloon, you probably need to replace the lamp.

We have used Chicken of the vnc in the past. You might need to enable some stuff in the sharing preference pane. I think its on sourceforge.

Have you tried a pc/laptop on the same network port? What sort of switch are these connected to - does it do POE or anything? Can you set up a mirrored port on the switch and use wireshark to see whats going on? Also do you have ipv6 set up on the network, or on the mac?

Ok, Phpmyadmin uses the terms columns and fields, and they basically mean the same thing. You need to find the type of the field called "ical_recur_id" in the entry table, and create one with exactly the same name and type in the repeat table. 1. Load up PHPMyAdmin. 2. Select your MRBS database. 3. In the list on the left side, click on "mrbs_entry". Then click "Structure" near the top of the page. 4. Find the column "ical_recur_id" and make a note of the type (Probably tinyint or int). 5. Click on "mrbs_repeat" on the left hand side. 6. check there isn't a mis-typed column field similar to "ical_recur_id". 7. just after the list of columns/fields there should be a line that is like: Add [1] Column(s) [Go] 8. Click [Go] button. 9. put in the column name "ical_recur_id", and set the type to whatever you found in step 4. 10. click save or ok or similar to apply the changes. You should then be able make a recurring booking.

have you added this column to the database? If so, you need to add it to the repeat table using phpmyadmin, or the command line mysql client. The type needs to match the column in the entry table. If you've already done that, check its spelled the same in both tables.

Nagios and Spiceworks are worth looking at, and are both free. I setup nagios to ping all our switches and a few external services every couple of minutes. We then have a webpage displayed on a pc in our office that shows a logical map of our network. It takes a bit of work to set up, but isn't that hard. It can do more monitoring than we use it for. Spiceworks is useful for discovering devices and software on your network, you give it the ip range(s) to scan, and the user accounts for the computers, and it will automatically do all the rest. It will show software versions, hardware specifications, some warranties, toner levels on network (but not local) printers, and quite a lot of other useful stuff. It is a bit dependent on what hardware you are running, and the update frequency isn't really fast enough to do real time monitoring, but its really helpful for diagnosing issues. You can set it up to email you if devices are disconnected, or to email you when it finds new stuff. It also has a help desk module if you need one. I think it can do a bandwidth/time graph for some of our switches, but not all of them.

HSS do some powered tools HSS Hire - Breakers Tool Hire and Equipment Rental. If you ask in your local hss shop they can probably help. Edit: dont know if you could get one of these through the doorway? http://www.hss.com/g/47015/Mini-canopy-.html
