This sounds similar to what's been done to speedup FaaS cold starts - snapshot the VM after the startup code runs, then launch functions from the snapshot. E.g., https://www.sysnet.ucsd.edu/~voelker/pubs/faasnap-eurosys22.....

Sounds like a cool class project! If I understand your approach correctly, this is how live virtual machine migration typically works (e.g., https://none.cs.umass.edu/~shenoy/courses/spring18/readings/...). It also sounds similar to this "remote-fork" concept: https://www.usenix.org/system/files/osdi23-wei-rdma.pdf.

The bridge is part of I-695, which is a beltway: https://en.wikipedia.org/wiki/Interstate_695_(Maryland). Inner loop refers to the inner lanes (traveling clockwise), outer loop the outer lanes (traveling counterclockwise).

They aren't independent, the city will tend to build up along the transit lines due to the easy access to transit. E.g., the NYC outer boroughs and the DC metro area.

The title of the Ceph mailing list post is "Red Hat’s Ceph team is moving to IBM", which makes it more clear what's happening.

> Lots of people are rushing to defend Mudge, and maybe it's warranted, but being an alumnus of cDc and l0pht doesn't make one a competent executive.

He was also a DARPA PM, which definitely requires management/executive skills.

I'm pretty sure I needed to mess with xorg.conf and other settings to get things like screen resolution and Compiz working correctly. I don't know what part of the stack was responsible for those issues, but I thought it was related to the graphics driver.

I could be misremembering though, this was 15+ years ago now.

If I remember correctly, the open source ATI drivers were always a bit buggy and it wasn't that easy getting them installed either. The tradeoff was always Nvidia: proprietary but works well, ATI: open but buggy.

Full of ore and people! Like you said for a long time there weren't any roads into the interior of Mauritania so that iron train was the main link.

I feel like most commenters here didn't read the article - in many cases a single soldier /can't/ take out a modern tank because of their active protection systems.

I was talking about walking - for biking, I was taught to ride with traffic.

I grew up in the states and was always taught to walk against traffic. Not sure where they're teaching people the opposite.

In the NYC area off the top of my head there's been the Tappan Zee bridge, the East Side Access project bringing the Long Island Rail Road into Grand Central Terminal, and 2nd Ave Subway Phase 2. Penn Station Access is being discussed, as is the Triboro RX line.

ETA: If you're curious NYC has a dashboard of capital projects >$25 million here: https://www1.nyc.gov/site/capitalprojects/dashboard/dashboar.... I think the complaint that we don't build anything in this country anymore is sometimes overstated.
