My experience is this mostly between men and generally not as common as it used to be.

My dad is called by his surname by some of his high school pals and call some of them by surname when he's around them (but not in reference to them if he's talking to me). Thinking back to my high school days in the late 00's I can only remember athletes being called by their last name. Perhaps because of football or sports that you just have your last name on your jersey. It would be an interesting thing to understand more.

I could be regional too. I'm from the US in the midwest.

I believe they mean realizing that if you had invested into stocks instead of money market you'd have likely realized a quite large return. Money markets seek to keep your returns to around inflation.

It's tough. iperf is a reasonable tool. It works by setting up tcp connections and actually transferring data.

I like the work https://fasterdata.es.net/ does. They provide clear guides and set expectations if you want to get more bandwidth out of a connection.

MTR is a useful tool but it is a somewhat common source of illusory issues since it generates so many icmp time exceeded packets that routers stop replying to other folks running traces. It's important, as others said, to understand that these aren't testing the data path of a network but instead the control plane path.

I've read about three chapters and this is very funny in a way that I don't find very often. It's more a hallmark of older pieces.

This is a breath of fresh air compared to the tesla approach which seems to be don't release any data that isn't biased. Waymo is being a responsible party here by releasing all this data even if some of the stuff around the waymo driver hitting roadway objects (like the parking lot bar or the shopping cart) is a little concerning.

I think those devices could use the psk option?

Part of the issue is pressure to audit EITC recipients.

"a baffling twist of logic, the intense IRS focus on Humphreys County is actually because so many of its taxpayers are poor. More than half of the county’s taxpayers claim the earned income tax credit, a program designed to help boost low-income workers out of poverty. As we reported last year, the IRS audits EITC recipients at higher rates than all but the richest Americans, a response to pressure from congressional Republicans to root out incorrect payments of the credit."

Personally I think you should strike this "(...because failure is not an option! ;) )" it's a little offputting. I also think you should put a salary range. I get how it kind of reveals your hand but it also sets expectations.

The title is so vague but here is the subtitle:

The Nth Country experiment showed that three post-docs with no nuclear knowledge could design a working atom bomb.

I think you have it right. I study for a lot of certification exams (They are very popular in networking and security), I've found that a lot of content around learning has moved to videos rather than "exam guides" produced by the vendor/company offering the video. It could be styles of learning thing but I much prefer the written content.

It strikes me that one advantage of the written word is that the information density is so much higher than in other mediums. I generally watch the videos at 2x speed and still feel like I'm not learning as much when I read for an equivalent time.

However your point about "what" you read is well taken. Just as in watching youtube or movies you can read trash just as you can watch trash.

Thanks for the reply! Nice talk! I spent around a month going down the perfsonar rabbit hole and set some cool stuff up. It was really instructive. At the end of the day work didn't operate a large enough network for us to get great insights from the perfsonar network.

I wish the article had mentioned more about the tools they use to track performance of links. My guess is a lot of perfsonar https://www.perfsonar.net/ or iperf nodes. Network performance testing is tough. It's interesting to hear of a company doing it

When I ran cross country in high school our coach always said to go on the sight of the smoke not the sound of the shot. This was when the starter was in front of the whole mass of runners. Not sure if it ever helped me given we were mass starting a race that lasted for 3ish miles.

I think 24 hours would be too slim. BGP is "routing by rumor" across a lot of AS's. I think a week would be more interesting allowing for route propagation to be a little slower. Obv this requires the spec really changing which in the case of BGP is unlikely to happen other than little tweaks

This is one of those cases where both sides have some insight depending on viewpoint. The OSI model is like every other model. It isn't reality (at least in TCP/IP) but instead is a helpful abstraction esp. around troubleshooting and understanding networking concepts. There comes a point where the model breaks down but that doesn't mean it's an unhelpful model just that it isn't a complete picture. I try and work networking problems through the OSI layer model but am aware when things don't really fit well into it (MPLS, MSS, ARP, Layer 5-7).
