ok I probably don't want to know but I also have to know - why not choose another way to deal with that capacitor, like removing it or making it smaller or adding a bleeder resistor

Cooling of these racks was a big deal. 720 devices stuck in a rack each with a TDP of 6 watt gets insanely hot. Early tray designs had this center channel cut out because we thought we needed better airflow.  Unfortunately, the trays were also very densely packed into the rack and and were heavy. A combination of two separate design flaws lead to the trays sagging and resting on top of the tray below. Which was Bad. One design flaw was that the trays rails for the raid were bolted in with only a single bolt, you can sort of see it here. This meant that when the heavy trays were set in, the rails themselves had a tendency to rotate downwards slightly causing that 1.75 inch RU to become more like 1.5. So we had to redo all of the rails to instead have two bolt slots to prevent that rotation.  The other flaw was having the channel cut out in the middle. With the channel the trays would flex and sag just from the weight. The very first workaround for this was to throw more zipties at the problem and make a bit of a hammock to catch the cable bundle before it interfered with the stuff below it. Sliding the tray into a rack had the tendency of ripping off the pinheaders that connected over the top of the Nvidia boards (the thing necessary to power them on and off with the arduino) because of this. Also they were near impossible to pull out once slid in. Plan B was to find a more solid bit of structural support. The most readily available such material we could find in 15 minutes was donald trump campaign signs. Solid, wouldn't melt, not made of cardboard, lightweight. So we literally stole a few from the side of the road and fished a bunch out of datacenter dumpsters. They were cut them up and slid over top of the channel and it fixed the problem of the cable bundle drooping until we could get the next batch of trays made.

Also notice that there isn't any kind of persistent storage on those trays for the NUCs. It was impressively hacky to get 720 devices per rack pxe booting to nfs root filesystems. I had a nasty shell script that would scrape the arp table of the top of rack switch to get a list of all mac addresses and the physical tray they were on (tray 1 = port 1) which were used for templating out dhcpd.conf entries and tftp configs for each device. Then we'd have a whole bunch of zfs-backed filesystems we'd clone out and let the devices mount as their root fs. All keyed by mac address of the device since that was the only real piece of identifying information available before bootstrapping.

I know this is cutting it fine time-wise, but I see a lot of "what you know" and not much on "what you've done". When I'm looking at resumes/CVs, I like to see what projects have been worked on. Have you materially impacted the implementation in any way (say you were the lead on Project X which was done to achieve Y). Did you realize the objectives of the projects (saved X man-hours per week/month/year leading to a cost savings of Y). Numbers are impressive. For example: "Building custom automation scripts with Bash, PowerShell, Python, RESTful APIs". So what practical application of this have you done? Tell me what you did as well why you did it and what the overall result was. I also like to see these broken down by work history. It gives me an idea of overall progression in your career. It's likely time for you to move to adding another page (or two). I have no problem receiving multi-page as long as they are relevant to the position. I'd prune anything you think may be irrelevant to the job you are applying for. In the past I've more or less customized my resume to highlight my history and knowledge that matches up with the job listing. Finally format: I like to see work history up front with relevant bullet points for each. Followed by any additional 'what you know' you think is important and any education/certifications at the end.

Explaining, and showing how you used these skills in your work experience will count for more than just listing them, and I'm more familiar with having the work experience ahead of the "other skills" section. I would disagree about putting it to two pages if at all possible though. Sometimes it's better to have one page of highly relevant skills that stand out to the recruiter or hiring manager rather than two pages of all your skills and they inadvertantly skim over the ones most relevant to the job. Good luck!

Also I'm 24 so alas, 4 years and change is all I got! Kinda exciting to think about how much cool tech I'll get to play with in the next forty years or so though.

Change quote:Buildinga secure, production-grade SAML auth based Cisco AnyConnect VPN, currently with 100% uptime, within 3 hours of touching a Cisco ASA for the first time quote:Building a secure, SAML auth based Cisco AnyConnect VPN on $DATE, which has experienced zero downtime since entering service. "within 3 hours of touching..." gives off a real "where angels fear to tread" vibe and could turn off some shops with a more conservative mindset. It may be something you can bring up organically in the course of the interview. You'll have a better feel at that point. I'd definitely leave the "production-grade" off as it implies it wasn't an official project used in a production environment. You have the space, so I'd add any other work experience even it's just brief entry level/internship stuff. Most places would expect 10-ish years of general stuff. If you're relatively young in either age or IT experience it's not as important. Definitely give it another eyeball for typos, things like missing spaces between words (like I found in my example), and using homonyms (there/they're/their) by accident. But wait until tomorrow AM if you can to do it. Too fresh and your mind can elide over that stuff.

Dear Diary, I moved my workstation and everything related to it into a spare room. I should have done this much, much sooner. For some reason, even though I moved every device, I now have about half of the cables i pulled out of the rats nest as leftovers. This is some weird poo poo. Also, the room has horrible acoustics. It's basically unfurnished, wooden floorboards, naked walls 2.8m high, 2.3x4.2m. My mechanical keyboard sounds like the SATAN typing. So I did what any reasonable person would do and spent 100€ on acoustic foam. Apparently BASOTECT is the hottest poo poo so I bought a 2 m² of 7cm thick foam. Let's see if it helps…

I'll see if I have to construct wool stuff later. For now I have two bags of old clothes sitting in the corners to take some of the bass out. My mic didn't pick up my typing this loud before, but now I'm sitting between two naked walls and I sound like the angriest typist on the planet. Like, so angry I'd bash your head in with my keyboard, then type your obituary with it. Because it's Hitler's Buzzsaw Keyboard and I can do that. I'm barely exaggerating.

I am becoming jaded in projects much easier than normal. I was in a meeting today where someone setup a bunch of K8s for things that could be handled by some loving lambda functions. It even has a virtual machine in the build to facilitate the k8's for incredibly weak reasons. It also has an SQL database. This is for a product that is going into aws. I asked point blank why this product needs SQL and the answer I got was "I know SQL better than the other options". I also heard a person say "I need the messaging bus to be kafka because its the only thing that will work.". Today I am going offline much earlier than normal.
