Thinking of getting an IT related number plate?...

SIMS 2016 Migration Tool - Install SIMS Server on Destination or not?
IrritableTech replied to LazyD's topic in MIS Systems
I would recommend using the migration tool to move your SQL. If memory serves the documentation does explain you have to run the process twice - once to extract and update the database, then on the new server to import it? I'm afraid it has been a while since I have done this. I think there is capita documentation available for installing the core packages onto a new server too. It involves running the installer for the version of sims you are using (you can extract this from Solus3) and ensuring the 'this will be the server tick box is ticked. There are a few places you need to ensure are set correctly for your new server - the DMS folder for example. You can copy the content from the old server but the path must be updated to include the new server name for example. Jump on the capita support site and do a lot of reading - I ended up getting info from a few documents and writing down my expected steps - which seemed to work fine. This was a while ago though, and I didn't have to do Solus3 or discover at the time. By using the upgrade and extract tool remember that your old server is basically untouched (as long as you stop SQL afterwards to stop anyone getting in!). If the new install doesn't work you can fire up the old one and think again. -
First things first... On a client run command and type.. nslookup my_server_name (replace my_server_name with your server name) It'll show you what is resolving your DNS.

POE Switches - which Wattage version?
IrritableTech replied to mdrabble's topic in Wireless Networks
Just a note. Our external PTZ cameras have a local power supply, so not all external cameras need PoE - your's might though. -
Managing IT jobs list over summer holidays
IrritableTech replied to DrBeaker's topic in How do you do....it?
I generally flatten a cardboard box and write on it with a sharpie. It's something I've always done working at festivals - quick, plenty of space for lots of jobs, not easily lost and gets the job done! -
I printed one for mine today :-)

Ok. Your UPS is probably a modified sine wave inverter, and sadly a fridge compressor won’t run very well or efficiently on MSW. So straight away the UPS might not be the best solution as is. You could probably charge the batteries within it without any real issues, but you’d be best off solar charging the batteries to a lower level to ensure you don’t fry the inbuilt charger. Most UPS’s I’ve used are setup as 24 volt systems - two batteries in series. This is because it’s generally a little more efficient to boost and invert higher dc voltages (boosting ten times 24-240 rather than twenty times 12-240). So as you can tell I’m not sure the UPS is the best solution - unless that’s all you have. How big is your solar panel? What is it’s open circuit voltage (the voltage under sun when no load is connected), what is the maximum power point (the voltage where it actually can produce its full rated power) and what is it’s closed circuit current? You’ll need to consider these to buy a suitable charge controller. Buy some fuses. Fuse your battery and your loads. Fuses are to protect your wire, not your appliance so rate them accordingly. A twelve volt system with a small solar panel will keep a camping fridge running for a while in the summer. Then once your comfortable you can expand ;-)

My shed runs on eight old UPS batteries (and 140 lithium ion 18650s) all charged by solar. I use them with invertors for a few items but generally try to plug in low voltage things to cut down on wastage. You don't need a bright day to charge batteries, just the right amount of solar panels configured to output the right voltage, pointing in the right direction. Take a look at my system on Jan 1st this year... 100 watts of panels only producing 30watts at their peak was enough to float 136 amp hours of lead acid batteries. Like @bald_pig asks - what is the idea?

WDS Not working after rebooting the server
IrritableTech replied to Uber22's topic in O/S Deployment
Had a similar issue earlier this week at another school. Windows update caused an issue with the tftp server. In WDS right click and choose properties of your WDS server. Choose the TFTP tab and untick Enable variable Windows Extension. Might work for you. -
We've a pair of these https://www.netgear.com/support/product/M4300-12X12F.aspx We use them for two redundant iSCSI paths. The fact that two can bolt together in a single rack unit was handy due to space limitations. They've run now for three years without missing a beat but we're not doing anything fancy with them. I'm not a fan of the netgear management interface.

Live Register do work with Tucasi - we have used them in conjunction with each other. We still use Live Register (we've been pretty pleased with them) but now use it with parent pay.

We have reported this to CPOMS - they are aware.

News regarding ICT4C/YHGfL?
IrritableTech replied to enbiggen's topic in Yorkshire & Humberside Grid for Learning (YHGfL)
Yeah, in the HTTP or UNC path just pop 'Sophos' That's how ours is. -
News regarding ICT4C/YHGfL?
IrritableTech replied to enbiggen's topic in Yorkshire & Humberside Grid for Learning (YHGfL)
Wow - it lasted that long? We just 'update from sophos' using our reissued licence username and password. If you haven't got a reissued licence then I would email [email protected] sharpish. -
I’ve had one in my name too. I believe the unedited version of the register is available to the political parties? I think they are using the data provided to them legally. [edit] “Political parties, MPs and public libraries may also have the full register.” Ref: https://ico.org.uk/your-data-matters/electoral-register/

You could turn of decryption for Guest devices? No cert required then. -
In which case you might find few companies willing to install Unifi and support long term. Anyone can sell a unifi AP so profit margins are thin and the support is generally community based. Ruckus is a different solution with regards to both of those factors. Unifi do offer a premium support service now - but I think it is there to encourage big businesses to use the kit. We've never had an issue with unifi that a quick google didn't fix.

Early days, had it less than a week but I think it's great so far. It's a bit weird getting used to electric - no gears, quiet and with it being hybrid an engine that makes noises not directly attached to pedal pressure. The petrol motor kicks in when needed with no real noticeable signs. Haven't towed with it yet but the reviews were that it works pretty well. Max 1500kgs towing capacity though is worth noting. It's 100kgs less than the diesel version. 75kgs nose weight max. Mines a 2015 model so has the slightly smaller battery. Charged it up from empty last night and put 8kWh's into it - which is about right if the BMS saves the lowest 20 and highest 20% for longevity of the pack. It claimed 27 miles range this morning - but my previous full to empty test got 23 miles pure electric - driving conservatively but up and down some hills. 14p/KWh means it is costing me about 5p/mile in electric. I was doing about 17p/mile in my diesel on a good day. Sadly not - electric motors turn into electric generators when they are turned by mechanical force - and that could break the management system or over charge the battery. You need to be put on the back of a truck if your EV can't move under it's own power.

I'm guessing here but the ipad pro has a faster processor and a higher resolution screen and therefore a higher current is required to run it. So it has a bigger battery which takes longer to charge and I think it may also have an initial charge at a higher rate (2.1-2.4 amps) rather than the older ipads which were lower. So your charging bay is having to work harder - creating more heat, the ipads are charging quicker - causing more heat. In an enclosed space in a warm room... Not sure about the stacking thing - I can't see it referenced, but surrounding lipos fast charging doesn't seem like a great plan to me.
