Things the documentation doesn't make quite clear - Part 78

Image
So yeah, per the AWS ECR docs , EC2 stores your images in S3.  What they don't tell you, unless you really go hunting , is that This isn't just a feature, but something really relevant to you because  You'll need to be able to get to S3 to push/pull image Which may not matter till you, till you end up spending five hours trying to figure out WhyTF your wholly private VPC can't pull images from ECR. Oh yes, you got the NAT gateway set up, and can do pretty much everything  else (including pulling from DockerHub ), but not from ECR. Sigh. It's good to know that the quality of missing information in AWS Documentation remains as high as it used to be. P.S. The fix is easy - a VPCE.  But that's once you know the answer...

Ridership vs Coverage - There *is* a difference...

Image
Jarrett Walker makes the point that public-transit decisions are not made in a vacuum, that there are actual tradeoffs that need to be made between Ridership  and Coverage. If public transit agencies were charged  exclusively  with maximizing their ridership, and all the green benefits that follow from that, they could move their empty buses to run in places where they’d be full.  Every competent transit planner knows how to do this.  Just abandon all service in low-density areas, typically outer suburbs, and shift all these resources to run even more frequent and attractive service where densities are high, such as inner cities.  In lower-density areas, you’d run only narrowly tailored services for brief surges of demand, such as trips to schools at bell-times and commuter express runs from suburban Park-and-Rides to downtown Mind you, this goes dead against the idea of Coverage  - if you told the people who were squawking about "empty trains...

The System76 "Lemur" - a quick Review

Image
My main laptop is a 15” 2015 Retina MBP/OSX, and I do most of my linux work via Vagrant and/or AWS.   The Lemur  exists mainly for build/test work and making sure that "stuff" still works for our non-MBP developers That said, in no particular order - Ubuntu Just Works out of the box.  Which is, maybe, the single most important thing that I cared about.  No fiddling, no messing around.  Just worked.  Sooo, mission accomplished in that sense. What the heck is going on with the weird battery bump?  it tilts the keyboard up just fine on a desk, but gets very weird  if you're typing with the laptop on your legs. The whole things feels sort of plasticky. Not in a *bad* way, but in the same way most android phone feels somewhat plasticky as compared to an iPhone The keys also  have a slightly plasticky feel.  Again, not in a bad way - they’re actually quite good. Come to think of it, the "plastic-y" feel I'm referring to is...
