What poor NVMe are you buying that gets 90MB/s? Even the Gen3 Kingston 256MB drive I have does well over 500MB/s in my iozone tests on a Dell Precision 3420. The only time you need mobo support is if you want to boot off NVMe bu

Conceptually, an Operator is intended to embody the knowledge and processes of a human operator for a given functionality. Extending the Kubernetes API might be an implementation detail but it’s entirely optional to extend it. Most Operat

glibc’s pre-main code is still far larger even with optimized flags. It’s at least a couple KB of disk. You can see the flags I used. I think only ‘-nostdlib’ has to be removed. Some of the code & data glibc adds has purpose (like T

Also worth noting that you should be able get the binary close to 2KB if you pass some other options. https://github.com/lpsantil/rt0/blob/master/STATS.md

I’d also argue > decent amount of stuff that CAN be done in _start before you run main It’s all optional. Before I found the Linux kernel’s nolibc [0], I wrote a minimal C runtime based on bunch of stuff I read [1]. Only thing

-fomit-frame-pointer is pretty high on the list of most destructive micro-optimizations in the history of open source. When you repurpose the backtrace pointer (RBP) for other things, it totally savages our ability to have native back

For a non-gaming use, I followed Shelby's/TechTagents' [0] guide for setting up an EEPROM programmer in Fedora 36 with Wine. I've been able to backup and flash several EEPROMs for my EMM8088 [1] XT replica, including BI

I started at JPL in 2002 and worked with dozens of groups. Including many folks who had been at JPL since the 70s. No one ever talked about Lisp. I remember helping a former team member who had transitioned to ground systems port an old

Been almost 15 years since I was at the Lab but I don’t recall Lisp being at all popular. And I started there as a Perl & PHP developer before transitioning into Java.

I second this comment. I spent the first 8.5 years of my career at JPL as well. My first project out of college was writing testing support tools for the Mars Exploration Rovers (MER) Project. I sat 10 feet from a small window into the S

As matter of practice, I always install git-bash or MinGW or CygWin on my Windows boxes. There's only one instance I've found where these solutions were not sufficient for my uses cases and it was an admittedly horrible corner ca

I like similar tricks. Another trick I like to use is being able to do a `make showconfig` and have it print the list of variables & their values that I care about. You can see that here. You can also see my Make+BASH solution for doc

That works well if you have targets with simple comments that are directly above the target and don't extend beyond a single line. It may be important to provide several lines of help. This gist has other solutions as well: https:&#
