The author is right that USB-C docks can be used to hide malicious devices - but the same is true of any USB device. You could hide a Pi Zero in a mouse, keyboard, memory stick, or anything else that you can open up and access the USB headers. Scary - but also requires a higher level of physical access than other vectors such as phishing.

Sure - but I'd rather not tunnel everything through a VPN, especially given the fact that I already have relatively high latency.

I've been using Starlink as my primary internet provider for the past year. I'm just outside of Eugene, OR and prior to Starlink my only internet options were Viasat or dial-up.

I definitely notice the variability of Starlink. My download speed ranges from ~40mbps to ~200mbps, and my upload speed ranges from ~5mbps to ~50mbps. This doesn't really seem to be connected to time of day or what I would expect to be typical use patterns. My internet is never unusable for Zoom, streaming video, or other average use cases.

A lot of people complain about decreased speeds, my personal experience hasn't really shown this to be true. What I have noticed:

* Over the past year, I've seen a huge improvement in latency and packet loss. I used to have latency in excess of 130ms, and I would typically see a few dropouts lasting ~30 seconds per hour. My latency now is rarely more than 60ms, and I never have dropouts.

* Being behind an IPv4 CGNAT is annoying. I get a lot more captchas and fraud prevention techniques being applied in my browsing.

* Geolocation is way off. I wish SpaceX did a little bit more effort to dedicate IP geodata to specific cells in their network - everything defaults to their Seattle POP for me.

* The adoption of Starlink out here is astonishing. Virtually every house near me has gotten it in the past 2-3 months. It's a huge game-changer for people. It's pretty amazing what the Starlink team has built out in a relatively short amount of time.

Often BDR calls don’t even focus on if the product is a good fit - it’s “how much budget do you have?” “Are you the decision maker?” “When are you looking to make a purchase?”. That’s, frankly, a waste of time for me. It’s one thing to have an initial call to show off core functionality and see if there’s a good fit - but if the focus is just trying to determine how much money I have, then it’s going to leave me fairly annoyed that I spent time on the call.

This is more of a post-sales item. A pivotal part of a renewal is going to be how successful implementation is - and that success is largely dependent not just on the sponsor of the project but on the team that supports them. Those folks are often the ones who don’t get the trinkets. Something like a nice jacket or even a pair of socks can go a long way to building positive sentiment there.

Seems to be a fair amount of recent interest in 10gbE home networking. I bought a Brocade ICX6450 based on this thread with 24 Poe+ ports and 4 SFP+ ports for about $100 on eBay with free shipping - it works amazingly well and powers my entire home network.

Bit of a learning curve, but I found the CLI interface to be similar enough to Junos, which I learned while managing EX switches.

I didn't expect to learn much from this article - but it actually really resonated with me. I often am responsible for purchasing decisions and found much of the advice to sales reps really insightful.

(1) The number one thing that bothers me is when I reach out to a company to explore their product and I get scheduled with a BDR who's sole job is to "qualify" me as a lead. I know BDRs are in a tough spot - but if you have someone reaching out and interested in your product, take advantage of that and get them straight to the person who can demo and answer questions. I'm shocked at how many companies make me want to prove myself as a customer before spending time on demoing.

(2) Ask before recording meetings, and if someone doesn't want to be recorded make sure you actually have the ability to turn that recording off. I've been on calls where the person who set up the Zoom/Gong wasn't on the call, and so no one had the ability to stop recording.

(3) The details of what is shared on calls is often completely lost. Every time a new person gets on the call, they ask the exact same questions that have already been answered. Make the customer feel as though you're interested in their business, have discussed their pain points, and have a plan ready to help them.

(4) Discounting discussions are always a pain. It's a game that no one likes to play.

(5) Offer to send some swag to the implementing team at your customer - not just your champion. It's a nice gesture and goes a surprisingly long way towards building positive sentiment.

Yeah, optics or DAC cables are definitely preferable. I wouldn’t run more than one or two 10G-BaseT units in most switches - but when you have a modem or device that only supports it, it’s a much cheaper way to get connected than buying a dedicated switch.

For about $50 US, you can get a 10Gbase-T SFP+ module that gives you a copper port at 10gig within a SFP+ form factor. That, coupled with a cheap Mikrotik switch, is plenty to get started.

Second hand Brocade ICX switches are also plentiful and not too power hungry (but they can be loud).
