We developed Object Mount (formerly cunoFS) (https://www.storj.io/object-mount?hn=1) specifically to not rely on any metadata storage other than S3 AND preserve 1:1 mapping of objects to files AND support for POSIX. We have a direct mode that uses LD_PRELOAD to keep everything in userspace so no FUSE overhead.
This approach isn't right for every use case and juice might be a better fit for this sort of 'direct block store', but wanted to include it here for folks that might want something like Juice but without having to maintain a metadata store.
(Disclosure: I work at Storj that develops Object Mount)
When the cameras become a revenue stream for a city it is not a good thing.
Cameras have been installed to fine cars running red lights. The city then reduces the length of the yellow to catch more people and offset the high cost of the cameras. The shortened yellows cause increased crashes and fatalities.
Net-net the track record in the states is not great.
* I work in my unfinished basement, but often roam to recliners in the house because the basement is cold in the winter
* standing desk from IKEA
* 5K ultra wide LG monitor
* Thinkpad P1
* Microsoft ergonomic keyboard
* Regular run of the mill mouse
* Blue yeti microphone
* Currently using the laptop webcam for video
I get a lot of comments about being in an unfinished basement so I recently bought a green screen and some ring lights to try and improve my picture. The webcam on my laptop is too grainy for OBS to use the green screen, so looking to buy a new webcam.
Database indexes are definitely one of the most approachable concepts of databases for computer science majors. If you have studied data structures and Big O notation you have all the concepts needed.
While I agree that how a query planner works is one of the most ‘magic’ aspects, I think the output from the query planner in most databases is very approachable as well to regular common programmers and will get you quite far in solving performance issues. We know what full scans are (searching through every element of an array), etc.
The challenge is usually discovering that the jargon used in your database really maps to something you do already have a concept about and then reading the database documentation…
Matt Might was one of my favorite professors when I was in school. I hadn't learned about his son's passing until seeing this. Both Matt and his son are an inspiration to what can be done even in the face of the unknown.
I can't imagine the pain and anguish over the years that must have been felt as parents, so it was comforting to read about what kind of person Bertrand became.
I hope that if my son ever needs my skills, I would be up to the task so perfectly understated here: "Extending an artificial intelligence tool on the fly to analyze the data, Bertrand’s father found an unusual strain of pseudomonas as the likely culprit in Bertrand’s body."
Best of luck with the Bertrand Might Endowment for Hope!
