4/ hiking up to Kaweah gap I spend most of my time looking backwards as the lake drops and the views of Angel Wings open up. They look so different every time based on weather and time of day. Dramatic this day with the changing cloud cover. I’ve passed here a couple dozen times in my life and the novelty doesn’t diminish for me. I look forward to this all day.

A local gamedev friend of mine has been making neat voxel rendering tech. Basically it lets you make super detailed voxel scenes using more traditional mesh based level tooling. I think he's still looking for projects to collaborate with too.

I sure like those big and flat, smooth and warm metal servers, but for some reason both of them refuse to see my fresh and perfect Debian disk and, like before, want more disks from me, disks in RAID, otherwise they refuse to see it… oh these big greedy corporate brainless tin cans

The saddest part is that at the end of the day, I still haven't finished restoring this server, even though all the components seem to be working fine (except that one moment when I chroot-ed into the restored system, did `grub-install`, but forgot to `update-grub` afterwards, partly because the sbin directory was missing from the $PATH, and also because my cup was already empty, causing me to repeat all those steps again)

It was “examine”-ed by `mdadm`, but the format was actually designed for `dmraid`, so the kernel, after I deliberately poked it with the `partprobe`, easily recognized all partitions and allowed to mount them.
So I created a simple backup over the network (with tar and nc) and was ready for a cup of green tea.
Next actions, where I needed to create a partition table, format file systems and restore the backup, required 6 oz of espresso and a croissant

and next time the Dell server said that one of 4 drives was “removed”. Which, for RAID 0, means that everything is over and no tools to restore it. I don’t know why I put my faith into that hardware controller. (It was a demo project, so that decision of using RAID 0 was not critical).
So when I poured another cup of tea, this time Earl Grey, the 4 drives were reassembled on a special slides for the HP server

Day at work.
Drinking coffee, waiting for servers to blow out the fans (not football fans lol), pass all the checks, then delay for several seconds my choice to open the boot manager, then immediately fail so I can go to the settings, try to change something and repeat all over.
Later, drinking another cup of tea, I restored data from 4 SSD drives that worked fine in RAID0 array until one day Linux started spitting out input/output errors, one drive bay was insanely blinking with two green LEDs

@morgunkorn Someone should open a museum for all the MTG cards (like, print them on canvases). This would be my favorite place on earth

During my lunch breaks over the past week, I became captivated by the idea of infinite zoom in Mandelbrot fractal implementation using shaders and WebGL. For this reason, to make adjustments and apply perturbation theory, which will reuse calculations from a higher scale, that requires reference points, I wanted to visually understand how we create the original image. So for every pixel we calculate a sequence of coordinates. Some of them converge and create quite peculiar paths
