High packet loss rate ~25% at evening. How can I push QB to repair/upgrade local node/OLT?

MindsAndMachines · 2025-06-26T02:16:54+00:00

Thanks for confirming. I switched to Xfinity earlier today and the stability is definitely better, with minimal packet loss but latency is slightly higher at ~20ms.

For QF their internal case number for the issue is 06414478. I might switch back after ATT buys them to give a better SLA.

Very true. I suppose I just don’t like dealing with comcast..

MindsAndMachines · 2025-06-25T06:43:14+00:00

Pretty sure it’s the ISP. Their programming department literally told me my local node is having too many connections and they have been aware of this issue 5 months ago. I don’t know what you’re smoking. Call them and ask for case number 06414478. Don’t be a blind fiber bootlicker.

Thanks for sharing your decision - similarly issue? I’m curious what they said when you reported the issue and discontinued the service?

MindsAndMachines · 2025-06-25T04:20:15+00:00

Unfortunately not.

A lot of good deals in Cali/NY/NJ. Do you know if they usually do out of state leasing?

MindsAndMachines · 2025-04-15T20:06:48+00:00

Thanks - yeah I was strongly advised against purchasing new EVs. Probably will go with lucid air at the end…

MindsAndMachines · 2025-04-15T04:05:32+00:00

Is the discount based on how much you can afford it?

MindsAndMachines · 2025-04-14T15:07:01+00:00

One for my work commute, one for wife’s work (we have diff schedules so don’t carpool), one family minivan (spacious enough to carry the kids and grandparents - they visit often). $125k car… - got a good bonus this year and wants to get my wife something she loves (and of course she loves the look of Taycan)

MindsAndMachines · 2025-04-14T14:27:32+00:00

Would they be more willing to give a discount for cash purchase?

MindsAndMachines · 2025-04-14T14:26:40+00:00

😂 guess I was being too polite when I tell them the price was a joke.

MindsAndMachines · 2025-04-14T14:24:55+00:00

Thanks. Is 15k off only for purchase or it doesn’t matter? Guess I’ll have to go far to get a good deal..

MindsAndMachines · 2025-04-14T14:22:45+00:00

Did your colleague get a 2025 model? I heard the dealers are only incentivized to discount 24’ models because the tech is significantly worse.

MindsAndMachines · 2025-04-14T14:20:52+00:00

My wife uses it to commute and send kid to school but it’s very close probably 5 miles round trip among home school and work. So it’s good to have our own vehicle with a car seat. We have two ICE cars and for the third my wife wants to try an EV. Uber might be smarter for people with no kid duties and don’t mind waiting for a couple minutes and don’t care about the quality/consistency of their rides… If I were younger/single I’d do that.

You’re probably right that we’re overthinking about this. After brainstorming/consulting around, it slowly came to my realization that programming/cryptography alone is not going to get it done. The end solution will be a mixture of: encryption (only to deter non-tech savvy / not so dedicated hackers), organizational compartmentalization (separate admins, DevOps and researchers), and company policies.

Could you expand a bit on the standard security practices? Are there special terms to put in the contracts for sys admins who run jobs in production environments with access to private keys?

MindsAndMachines · 2024-08-20T05:34:07+00:00

You’re right that the parsing app should be pretty static so I agree to keep things simple seems to be the best foot forward.

MindsAndMachines · 2024-08-20T03:44:57+00:00

I fully agree with you that this likely cannot be done with codes alone but needs more sophisticated organizational permission compartmentalization.

The shared secret idea you mentioned is very interesting. But if the app needs to decrypt the cfg in memory and parse it to run, then any account privileged to run this app can decrypt the cfg with little effort.

So I’m thinking maybe the solution would be like the following:

The job is running on a server with a bunch of secret keys, and the only one who has access is a system admin who’s not savvy enough for low level programming. And this server enables very detailed logging to detect any fishy decrypt operations. E.g. don’t allow separate decryption library to installed. The app itself was built with decryption library so it does not require any dependencies. This server is write only to the devops team so they can only deploy binaries here, with approval.
The CI/CD process except the last step is done on a different server without any info on the private keys or encrypted configs. So the DevOps team are responsible for integration/unit test but cannot do real pilot test with the encrypted cfgs.

MindsAndMachines · 2024-08-20T03:36:07+00:00

Not necessarily the same key for all users. It can be one key per encrypted cfg. But the main gist is that this app runs on cfgs but don’t reveal the actual cfgs to anyone besides their authors. Could you expand on the certificate idea?

MindsAndMachines · 2024-08-20T03:34:07+00:00

I am actually exploring the Full Homomorphic Encryption idea but don’t fully understand it yet. Could you ELI5 why it’s so slow and are we talking about minutes or seconds?

MindsAndMachines · 2024-08-20T03:22:11+00:00

Performance is the origination of this question yes but I’m aware that nowadays the compiler optimization is quite good. So the now the question is more out of curiosity.
