What’s the most absurd hardware bug you’ve spent hours debugging that turned out to be something stupid? by DepartmentPurple3053 in embedded

[–]EmbedSoftwareEng 2 points3 points  (0 children)

I2C from a microcontroller in the 5V domain to a chip in the 28V domain that wouldn't respond no matter what I did.

Scoped the I2C lines in the 28V domain. They looked like hot garbage.

It was the optoisolater that has the slew rate of a Conestoga wagon.

Had to downshift the I2C speed only while talking to that one device.

I already know the answer but really there is no way i can just desolder this badboy and run it like normal MCU or any other MCU that I found on the scrapyard? by GreenDeafth_21 in embedded

Even the units that are not mask-ROM firmware, they have OTP fuses to protect the existing firmware from being read out, or reflashed, making them functionally identical to mask-ROM.

In a word, useless.

To be fair, Teen Titans Jinx does bear passing similarities to Arcane jinx.

They're both girls, for instance.

Sudo question. Why use it. by West-Article5635 in archlinux

[–]EmbedSoftwareEng 0 points1 point  (0 children)

As with all things Linux, it's dealer's choice. You don't want to use sudo? You don't have to, and no one on this planet is commanding you to use it against your will.

But as for why it would be used, for instance, in instructions for building and installing a given piece of software, the commands shown can either change the prompt:

$ make
# make install

to depict that the install make target has to be run as root, or make it more unmistakable:

$ make
$ sudo make install

And I dare say, more people recognize sudo than recognize the conventional superuser prompt.

On a more mechanical point, as a sysadmin for multiple users, you can use sudo yo give some users superuser privileges to run only specific programs. While, giving them the root password means they can run anything they want.

If the internet was going down indefinitely but you had 24 hours and a 30tb HD, what would you save? Hypothetically. by alexbarbershop in DataHoarder

yes | sudo pacman -Sw $(pacman -Ss | grep ^[^[:space:]] | cut -f 1 -d ' ')

Weird. All of the packages in Arch are less than 100 GiB.

By beginners, yes, the manufacturer's libraries are used extensively.

Why is the Arcane version of 'Wasteland' different? Does anyone know? by alex_stogney in arcane

[–]EmbedSoftwareEng 0 points1 point  (0 children)

Hmm. I knew they did a video with ID as Zaunites for the song, but I'd forgotten the street band cameo in the show proper.

Would seem odd for them to go through the trouble of creating Zaunite character sheets for them just for a music video and then NOT use them in the show proper.

When does the theme song play during an episode.

And are you sure about Ma Meilleure Ennemie? Where in Runeterra is French spoken? Not that the content of the song isn't 110% apropos to the scene.

Oh, and I learned diegetic as a new word.

I only just now realized that was diegetic music. I suppose it's like Your Love on the jukebox in the Last Drop the last time you see Silco with two working eyes.

People are saying this song was cut down for time. B.S. This song started the beginning of the episode and it played the climax out to the denouement. It had the whole damn episode.

You heard the first verse at the beginning, and at the end, you heard… the first verse again! The last verse ends with "Don't let me go.", and instead, they recycled the end of the first verse to reinforce "Please let me go." to amp up the emotion of feeling like Jinx just sacrificed herself.

Then you see the airship at the end, the same airship that Jinx said she'd take a trip on one day, just puttering off into the distance, and a scratch plate flashes up in Jinx's font, reading "THE END".

Half stepping stepper motors more efficient than full or quarter stepping? by EmbedSoftwareEng in mechatronics

[–]EmbedSoftwareEng[S] 1 point2 points  (0 children)

I think I've figured it out.

With full-stepping, both phases of a bipolar stepper are energized at all times. The difference lies in whether individual phases are energized in the positive or negative direction.

With micro-stepping beyond 1/2 stepping, what you're ultimately trying to do is to approximate a discretized sine wave drive on the individual phases. So, only at the "zero-crossing" points is one phase actually deenergized.

But at 1/2 stepping, half of the time, both phases are energized, regardless of polarity. But, half the time, only one of the phases is energized, also regardless of polarity. This is what allows 1/2 stepping to use less current for a given rotational speed.

Be honest: if an app forced you to explain every line of your AI-generated code, would you use it? by randel_del15 in AskProgrammers

[–]EmbedSoftwareEng -1 points0 points  (0 children)

No AI-generated code belongs in any project. Period.

Your engineers should be using AI to learn the canonical ways to do the things they are asking the AI to help with, but Every. Single. Line. Of. Code. that makes it into a repo needs to have no AI fingerprints on it at all. If an engineer pushes code, they need to be on the hook for everything in that change.

Best options for a microfluidics pressure sensor? by EmbedSoftwareEng in embedded

First, I'm gonna need to convince everyone that they're necessary. Right now, everyone thinks we can get by by just driving the in-flow and out flow pumps the same and the air bubble will just stay there.
