With all that free stuff why y'all using windows?

Anything with an open api, so when the provider pulls the service you can still manage it https://www.home-assistant.io/integrations/#doorbell

What sort of Fibre-Optic Cable do I need between switches?
dmj replied to Tom_M's topic in Wired Networks
Looks Good To Me. (apart from the pics don't match the description) I don't think SFP will auto negotiate speeds at all, when i said backwards compatible I mean you can put SFP+ into SFP. I still think you have to match speeds. Happy to be corrected on this. -

OM3 is rated upto 330M for 10GB. You should be able to get preterminated lc-duplex OM3 cable. if you are going under floors, consider getting armoured cable to avoid rat bites cutting through it. edit: SFP+ is backwards compatible with SFP -

We run all the infrastructure in gcp, so there is no need for us to route traffic between sites. -
myNCSC finding update Name does not match host alt3.aspmx.l.google.com.
dmj replied to k-strider's topic in Cloud Services
Your post reminded me that Google (and Yahoo) both introduced new requirements for those sending >5000 emails per day in feb 2024 TLDR is that SPF, DKIM, PTR records are a requirement, as is TLS for SMTP. I'd kind of forgotten about this as we were notified months and months ago. -

This doesn't sound like a Google issue to me, it has more of a DNS ring to it. Are you all using the same DNS provider by any chance? and are they proxying your records? What happens when you dig MX -
postman vs bruno Once you have your head around the API's, you'll need to learn the BQ API . Then it's just a matter of knocking up a script in you favourite language to do the sync. Python is well supported for this sort of thing. some examples / tutorials here https://realpython.com/tutorials/api/ https://cloud.google.com/python/docs/reference/bigquery/latest You may find that if you opensource your scripts onto github, others will want to use them and improve them if you accept PR's.

Late reply but getting the data streamed into BigQuery and then configuring looker for BQ would be the way forward here.
-
I've done lots of similar integrations, but if you are not able to maintain it you should buy. Salamander will be able to sort this for you (depending on the MIS and how good/bad their API is)

just drill a hole in it. Earthing is for wimps

Why? Don't all the cloud MIS have api's ?

It's a tool, not a benefit of the job. If staff are using it as a benefit and for personal use they need to be charged tax for it.
-
It's certainly possible, but you really need to compare to a known baseline, not really something you can just install an application and it tell you of problems. Something like prometheus (with the snmp exporter) and a grafana frontend would be ideal to create a dashboard of things you care about eg latency over certain links. You can then setup error budgets and notifications accordingly

Last time I looked at this there wasn't a gui to deploy applications. As long as you can get sshd installed, you can manage them with Ansible.

Interestingly, we measured this (it was 8 or 9 yrs ago, so I forget the details). We reduced the overall school power consumption because students were expected to charge their laptops at home in much the same way they were expected to bring in pencils etc. We reduced the number of IT suites from 8 to 4. Most of the servers moved offsite because we started using cloud based infra. The real expenditure was getting an access point in each room and a decent internet connection with redundancy.

Weird example, I've seen plenty of maths lessons using IT. Never seen a swimming lesson using IT though.
-
Yeah, the link is in the post. I was also quite surprised at how low that was. We introduced a 1:1 scheme back in 2016? I think, and the school still runs it. FWIW even 1:1 schools don't have 'all lessons' with a computer, but when they are there it is useful for staff and students to choose to use technology.
-
You'd think that IT in schools would somewhat reflect the workforce or the future workforce. Only 1% of UK secondary schools have a 1:1 program and only 70% have laptops for less than 25% of students. This sharply rises to near 100% at University. I couldn't find stats on employment, but I would wager more than 1% have exclusive use of a company computer.

Call me old fashioned, but whats wrong with a mobile phone and a wifi SIP? -
FWIW, being able to auto configure proxies and have different settings per network has been built into major browsers for the last 35 years. You don't need any extra software to do this if you have a DHCP server and a browser https://en.wikipedia.org/wiki/Web_Proxy_Auto-Discovery_Protocol

ClassCharts - breach or not?
dmj replied to notalot's topic in Data Protection & Information Handling
Presumably Cloud providers such as Arbour/Bromcom would have the same excuse, or Microsoft/Google for that matter if their systems were breached. it does seem a bit crazy that the school would end up on the receiving end of any fine for choosing a provider who suffered a breach. Or am I misunderstanding? that classcharts still could be liable, but one of their customers must report it to ICO for the ICO to investigate? -
On the point about the FSCS protection limit of £85k - it's moot if you have stocks and shares ISA because the stocks are not held by the provider, so if the provider goes bankrupt the shares are still protected. WRT the British ISA; I'd only do this as a last resort. If you live and work in UK you are already overexposed to the UK economy so investing in it is a very bad decision. Global ETFs are far less risky from an exposure point of view. LISA is a good bet if you don't already own a home and are under 40 Stocks and shares pensions (SIPP) is what I'm putting my money into. The Government pays in an extra 20% automatically.
