I drove through Iraq for a month in 2022. From Baghdad north to Erbil, then south to Fallujah and Najaf.

Men and women rarely interact, like many Muslim majority countries. It is odd for most people to talk to the other gender who is not their direct family. Found the stereotypes we have in the west of women were the same there but more exaggerated. A tough existence.

I’ve seen leaks impact my company directly 4 or 5 times in 4 years, so I would think often enough since we own a /9~ and don’t change our routes too often.

At my company (Fortune 100), we've been selling a lot of our public v4 space to implement... RFC1918 space. We've re-IP'd over 50,000 systems so far to private space. We just implemented NAT for the first time ever. I was surprised to see how far behind some companies are.

Note they have a new fee schedule, this would cost $500 in the fee to sell, and IPs are going for $48-$52 right now:

Usually if a response is greater than 512 bytes the DNS server will renegotiate on TCP 53. Note some DNS servers might not do this, but every normal implementation does that I’m aware of.

They're talking about the western slope, which would mean roughly Grand Junction to Durango in this context.

General question: where does this research lead to? As in what might be the next step for this research team, and/or their field in general? I always like to understand what discoveries like this could open up in the future.

5G really only works well in dense/populated areas. In central Colorado I'm lucky to get 4G LTE in town, and usually expect 3G. Most areas in the US west (Utah, Wyoming, etc) don't have any service. It's very different if you're way out.

If you have 4G or better, I'm not sure. Here's a map of 5G from ATT in Colorado: https://www.cellmapper.net/map?MCC=310&MNC=410&type=NR&latit...

For the TLDR people:

“ In each previous section, what was at issue was a discrepancy between two figures, both obtained from data provided by Columbia. Regarding class sizes, the information provided to U.S. News conflicts with the information in the Directory of Classes. Regarding terminal degrees, the information provided to U.S. News conflicts with the information in the Columbia College Bulletin. Regarding full-time faculty, the information provided to U.S. News conflicts with the information provided to the Department of Education. And so on.”

The big conclusions are that Columbia seems to be providing inaccurate data, and that one of the outcomes of chasing rankings are that transfer students end up as second class students, at least at Columbia.

I think it’s a data driven case of how elite universities can perpetuate a system of reduced social mobility. For Columbia, the objectively more poor transfer students support the more wealthy non-transfer students, and the graduation rate shows that disparity.
