AKA: We went for the most expensive option and can't afford to maintain it because of all the hidden costs.

I'm not sure even that is true TBH, given the number of issues reported on Edugeek compared to Arbor, who have a larger market share.

ok. apologies if you are who you say you are. Hopefully we can start afresh. The tactics that Bromcom employ lead me to these conclusions.

Looking at your ONLY other post , criticising a Bromcom competitor, I can see this is a shill account. I call BS. If only Bromcom could get their s**t together and update their systems to the modern era and not rely on PR/Litigation. I appreciate they've been around for a long time and have a lot of legacy stuff knocking about, and these things are difficult, but honestly...

Time and time again Bromcoms business practices have been called into question; whether it's their shoddy uptimes (where their own stats show 'no issues' ),withholding latency metrics, not adding adequate SLAs to their contractors, the shambles of a helpdesk to the point where the only way to get things resolved is on a public forum. Yes, according to the law they should not be excluded from bidding on spurious grounds, but schools don't have teams of lawyers on standby to do this properly: the result Bromcoms sues. Again.

Stop giving them ideas!

That's an ancient circuit. An ESP32 / ESP8266 would do all that with Wifi/bluetooth on one chip. Or an Arduino, or Pi Pico, or pi. There's a whole market for this sort of thing: https://thepihut.com/collections/adafruit-sensors

It would be nice if Science depts collaborated with Computing and D&T and built their own, they are so simple and all the sensors are readily available.

Seems a good move IMO. I do recall schools getting 'pupil' reviews comparing to prison camps etc.

Ripgrep is blazingly fast and free: https://github.com/BurntSushi/ripgrep I use it multiple times per day. My goto for searching inside files.

Take a look at some of the kits and bundles on the pi shop for ideas: https://thepihut.com/collections/raspberry-pi-kits-and-bundles

In chrome: Select "developer tools" > Network > Doc. Reload the page.

Most decent companies will publish their ip lists in a json export. (eg: stripe , https://ip-ranges.atlassian.com/ ) In this case, just add these to your firewall build scripts (which every good engineer will be running daily) and hey presto it automatically updates.

Also consider instrumenting with OpenTel from the start. You will thank me for that later

Everything in one instance is a reasonable choice, but if you want to scale consider: Using postgres over MySLQ - it's far more advanced for the sort of features you will need going forward. For example, you will want to dynamically scale and patch the instance with a downtime of microseconds. Good luck with MySQL. Also consider having Rails send read only data to a different URL, so that you can segregate your read only and write only DB connections

LMK if you need any advice on the devops side. What backend architecture are you using? Single database per school, single table or single instance? There's trade-offs for each so no wrong answer just curious.

Another irony is that the US restricted China from importing nvidia to stifle their innovation, and this resulted in them creating a more efficient technology

I'd spend the engineering effort in running clustered HA. Even the databases. You should be able to survive multiple region failures on a 'ground up' app as you don't have the legacy rubbish that Bromcom/ESS have to deal with. The DR site would hold the critical info.

You should. We're a private company and we negotiate our contracts with penalty payments for missed SLA's. Schools, certainly large trusts and LA's should be doing this too. Unfortunately, Bromcom don't like this sort of behavior and start mudslinging about 'kickbacks' when LA's negotiate with providers, without providing any detail about the contracts (that they were not party to) (see /forums/mis-systems/239744-schools-week-arbor-s-kickbacks.html)

How's it failing? Can't you just replace the batteries?

I think this will be for your benefit: If lots of parents are topping up early in a term, that's a lot of money to invest.

To find identical files, you're better off matching the MD5 hash - but I don't think this is what the OP is asking. Here's a python script that will do it: https://github.com/lene/DuplicateImages

Anyone tried with "A PE teacher needs to understand this". ??

It is a LOT harder to be compliant with GDPR if it isn't centrally managed, but I don't thing that's a requirement for compliance.

Your're giving them access to Python, why are you worried about Powershell ??? If you want to do this securely, you'll need to do so in an isolated environment such as a VM or on a dedicated server paltform.
