Open Source ERP system for Makerspaces and Community shared system.
Started out as a kanban style of system where anyone could request that we re-order cleaning supplies at a Makerspace. Has evolved to tagging assets and maintaining those assets and I'm working on adding ESP32 based device control to enable/disable devices through those QR codes.
I've always said that in the back of my mind, the most successful grocery store would be the 'walls' of the store -- bakery, deli, produce, meats, floral, cheeses, dairy and having a little selection of store brands in the middle where consumers can pick up (and vendors can pay a premium for endcap space, because they're the only non-branded products out there), with the rest of the SKU's behind the walls of the grocery store in a fulfillment only model.
Kroger should have pulled a Wal-Mart and turned to their shrink-heavy stores in urban centers to online fulfillment only -- basically only their delivery drivers can retrieve items for an order, and everything's shopped by an associate (Look south of the MicroCenter in Dallas if you want to see what one looks like: it still has the Murphy USA in the parking lot and is basically an unbranded walmart building with 'driver' and 'associate' entrances -- and then deployed the robotics there: less retail space, more online/fulfillment capacity (have humans grab produce and custom sliced/packed items, robots pick the dry goods), and while you lose some cashier jobs, you'll probably have net improvement in terms of time waiting to be picked.
I've eliminated Chrome from my personal systems when uBO stopped working. Blocking v2 manifests also broke a few extensions that were being developed for my day job: they've spent the last few weeks working on Firefox extensions and are almost at the point where they're getting ready to wipe Chrome from our corporate machines.
I'm no longer under this specific NDA, so, I can talk a bit about this.
It was well known in the wireless industry that ATT collected and kept the most data on all of the carriers: 7 years for text metadata, "7 years" for call history (I put that in quotations because it was rumored that ATT kept them indefinitely, but, there were technical limitations for restoring data that far back), and 7 years for the contents of the text messages themselves. Verizon was up there as well, but, I don't remember specifics.
The carrier that I worked with kept only 3 days content of the actual messages, 28 days for the text message metadata, and 28 days for the call records for their enforcement database, but, they could get calling records and sms envelope information for billing back 7 years, and at the time, we had to implement sharding at the database layer that maintained the warrant database due to the amount of traffic that we were receiving from the calling systems and the amount of queries/data that we were sending out, in near realtime, to law enforcement users who paid $10,000/month for access to that data.
AT&T wasn't storing this data out of the kindness of their heart, it was a (probably small) revenue stream for them.
I'm in a similar boat -- my educational background is hardware engineering, but, I've been a Linux nerd/SRE for the last 20 years. Ask me to test an 3x10 LED array? Can do it in my sleep, without even looking things up. Ask me to do a B-Tree? I'm pulling up documentation. Ask me to do a deployment in AWS, GCE, or Azure, and I've got the code to make the API calls without the help of boto...but ask me to do the same in VMWare, and I'm a fish out of water.
I've got a technical interview on Thursday, and they use Hackerrank for their coding platform. I'm seriously hoping that they have something that's specific to SRE tasks, because, if they ask me an algorithm question, I'm almost 100% certain I'm going to fail -- these weren't things that I studied in my EE degree, but, I've learned how to implement things from my positions over the last ten years.
I know what I'm doing, and I feel comfortable thinking and looking for solutions that aren't "inside the box" -- delivering an OS and DB upgrade to 8000+ stores via a USB Stick -- complete with a dashboard that I wrote, microservices soup to nuts (meaning: I worked with the developers to make better containers, and then wrote the ansible playbooks to deploy OpenShift in EC2) for a major hotel company, web governance/best practices for a top 5 Quick-Serve Restaurant chain. Asking me the difference between a Markov Chain and a B-Tree isn't something that I've ever needed to do...
On the other hand, when I was hiring in the Washington DC area, the number of Senior developers that I'd get from government contractors who couldn't count to 1000 by 5's in a language of their choosing really hurt my soul.
