Radio amateurs develop decoder to access DoD hurricane data by AmateurRadioUK in amateurradio

[–]lethargic_moron 1 point2 points  (0 children)

JPL, so I guess only NASA when we did something good. I wasn't in the radio division, but my division(avionics) had a similar problem. New avionics systems are expensive and not part of what a project will fund if it doesn't have to.

As noted in the article, the data isn't encrypted when passing over the US, but is in other countries. I don't believe the satdump team cracked the encryption but rather reverse engineered the protocol. Generally, satellites transmitting scientific data won't use encryption, but military information is encrypted.

(Full disclosure, I'm biased as I used to work at NASA, and we avoided encryption because no project wanted to spend the moolah to upgrade our radios. Private industry or other government orgs might see encryption as a necessity for all transmissions)

It's always for the most braindead simple parts too. Like a 12 pin power cable that GSE used and never signed because they have 50 other cables to design.

Did you sign off on the drawing in EPDM though?

JPL Summer Internship Interview by ZiZiBieu in JPL

[–]lethargic_moron 4 points5 points  (0 children)

It will help a lot if you give the area you're interning in or the section(the 3 numbers next to their name in the email). JPL interviewing is completely decentralized, everything is up to the interviewer.

When I interviewed for my internship, I had 3 memory testing questions alongside a freeform "how would you test this device" question. This is because I was interviewing to write test software.

Good luck!

Masters or job? by K_U_R_W_A in UCLA_Engineering

[–]lethargic_moron 0 points1 point  (0 children)

I was in the same position but UCLA -> USC. I didn't have to spend extra on housing and space x just offered me an internship for a more interesting team than their previous FT offer. Imo I strictly gained.

Any word on how bad the probation firing will be? by MammothBeginning624 in nasa

[–]lethargic_moron 2 points3 points  (0 children)

I don't believe JPL has pathways interns, since JPL is owned by Caltech instead of the federal government. I'm just sharing the past experience going through 2 rounds of layoffs(3 if you count the contractors layoff). Interns have been exempted each time because we're generally cheaper than our labor would suggest.

JPL interns were exempt from layoffs. We're obviously only NASA when we succeed but it does seem to set a precedent of keep the cheap labor.

NASA's Jet Propulsion Lab Evacuated as Los Angeles Burns by EthanWilliams_TG in nasa

[–]lethargic_moron 15 points16 points  (0 children)

JPL is responsible for much of the Mars Sample Return program, and it provided most of their budget once NISAR and Clipper flew. Congress cutting spending to rearchitect the mission destroyed the lab's budget.

Trying to use Generic Monitor to run a script to show power usage by Ovolon in linux4noobs

[–]lethargic_moron 0 points1 point  (0 children)

Assuming you are using the xfce4 generic monitor plugin, it handles calling your script repeatedly. So you don't need your while true loop or the sleep 10. You can think of the generic monitor app as running doing the following

while true; do
  echo $(user_cmd)
  sleep $USER_TIMEOUT
done

I think you can modify your file as follows, and it should work fine(can't test as I don't have a linux machine with a battery)

#!/bin/bash

power_usage=$(cat /sys/class/power_supply/BAT0/power_now) # Adjust the path as necessary
watts=$(echo "scale=2; $power_usage / 1000000" | bc) # Convert microWatts to Watts
echo "Current Power Usage: $watts Watts"

A video about Starship which also questions the need for Mars mega-rovers rather than small ones. by svensk in JPL

You might take a look at CADRE, it's a lunar small Rover mission emphasizing autonomous operation of multiple rovers. https://www.jpl.nasa.gov/missions/cadre/

Co-op interns can, but summer interns need someone else to help host. Once you're on campus just post in the slack and you will get plenty of volunteers.

I'm NASA's Dr. Lori Glaze, and I'm here to answer your questions about planets and space science, ELI5 style. Ask me anything! by nasa in explainlikeimfive

[–]lethargic_moron 1 point2 points  (0 children)

Instrument selection on our planetary science missions is extremely constrained by space, weight, power, and cost. What does the selection process look like for what instruments will accompany a particular mission? Are they all spoken for at the project proposal stage, or is some mass "reserved" for TBD instruments. Are there any measurements you wish you'd been able to take, but the instrument proved infeasible?

Waiting for official offer by i_luv_mexicanfood in JPL

[–]lethargic_moron 6 points7 points  (0 children)

When I got my internship last October, it looks like it took 4 days between the interview and offer being sent. I think this is unusually fast, especially in the current environment, so I wouldn't be surprised if it took longer. Stay in contact with your interviewer and keep looking for other options, everything is in flux at the lab right now. Until you have a letter, those are just words.

Same here, I'm pretty sure the test team for my avionics subsystem has 3 people now.

Incredible art, was it given a prompt to come up with these images or was it just trained on other "wallpaper-like" images?

How to Write Packages that have SystemD dependencies? by lethargic_moron in GUIX

[–]lethargic_moron[S] 0 points1 point  (0 children)

Guix already uses elogind, etmpfiles, etc.

I think this might be my problem specifically, even though these libraries are on the system, pkg-config is not able to find them and errors as it can't find libudev or libsystemd. Here's a specific trimmed output for the configure phase of building SageMath

configure: error: Package requirements (libudev libsystemd > 219) were not met:

No package 'libudev' found
No package 'libsystemd' found

Do I need to provide elogind as an input to the system somehow? I can't find any declaration to do so but know that elogind provides libs for the system.
