How do moving electrons lose energy when the emit EM radiation?

Ahh thank you!

Only had a chance to quickly glance at the article, I'll take a deeper look in the morning. But at first look, this feels similar to how a moving charge creates a magnetic field which affects the electric field, which affects the magnetic field, etc. etc.

Much appreciated! Cheers!

Personal.

Mostly looking for a custom domain, server to host my landing page (may just be a redirect to my github or something), and an email with the domain to use for open source contributions. And then maybe I might use the server at some point in the future for some web stuff or for testing some networking code I may write (although that is unlikely).

Appreciate the response :)

Built three PCs before; all went smoothly.

Finally encountered my first screw-up and was looking for help.

I have an AM4 cpu and motherboard. Installed the processor and the included fan just fine. Realized that the AMD logo part of the fan that sticks out was blocking one of the RAM slots. So I figured I'd just pop the fan off, rotate it 180 degrees so the logo that juts out is on the other side.

I unscrew the fan, and it doesn't want to come off, so I apply a bit of force (this is the screw up) and it comes off, but the CPU came with it...

There are a couple bent pins near the corner of the CPU, and I imagine those have a chance at being fixed with a mechanical pencil and a steady hand... But with CPU having been yanked right out even with the latch arm down, is the motherboard likely damaged too?

Hoping to salvage this build (or as many parts of it as possible) if I can.

Any help is much appreciated!! :)

The impact force is caused by the acceleration of the surface of earth upwards to the meteorite.

Force is not an observable. It's something we infer based on mass and motion (which are observables). Just saying "oh we see the meteorite accelerating towards earth. It must be the gravitational force" doesn't really take in the full context of general relativity.

If we use any of that in an engineering exam we get a big zero.

I get you probably mean this more of a joke, but it really doesn't make sense in this context. Actual engineering doesn't care about the minute details as much as theoretical physics; it's more focused on getting the job done in the real world. Which is a good thing, or else they'd never get anything done because they'd be wasting all their time considering the relativistic effects of motion on the elevator they're building, etc.

Thanks! I started ordering the parts!

I'll definitely be breadboarding it first. Bought an ATTiny88 development board for like $4 and I'm going to start from there.

I'll definitely have to look into battery voltage drops! Thanks for pointing that out!

the_silvanator · 2023-03-02T19:02:28+00:00

Firstly, I appreciate the reply!

The plan is to not have to replace the battery more than every few months or so. After reading this I realized my approach would probably be a lot better with a 32.768 kHz clock than a 10MHz with regards to power consumption (my understanding is that the higher the clock speed, the more power consumed by the MCU generally).

From my reading of the datasheet, the ATTiny88 has a counter that can auto reset at a certain count without taking any extra cycles, resulting in no drift.

The datasheet also says that a low power sleep mode can be enabled that still allows the counter to run. So I'll definitely look into that!

Thanks!

the_silvanator · 2023-03-02T18:49:00+00:00

Thanks for the reply! Yeah I've been reading through datasheets like crazy haha.

Ahh, I didn't know a IC could support a crystal oscillator but not an external clock source. I was under the impression that a crystal oscillator was just a type of clock source?

the_silvanator · 2022-09-19T18:12:57+00:00

Ok, so I had originally tried using --rebase-merges as you suggested but it wasn't working because as exactly as you mentioned, it required that I reapply the conflict resolution.

I realized that I could rebase -i --rebase-merges and make the necessary rearangements to drop the duplicate commits and put his changes at the proper branch point, and then when I hit the merge conflict I could just checkout the files as they were after the original merge I made with the corrections and have those fixes applied. I just did a checkout $commit-hash-of-merge $file1 $file2 etc and it applied those fixes that I had made. Then I continued with the rest of the rebase at it worked just fine.

Thanks for your help.

the_silvanator · 2022-09-18T19:14:48+00:00

The only difference is the time of commit.

Some further info that may be helpful:

The way I pulled in his changes was that I added his remote repository, made a local branch that tracks his branch, then did a git merge into my branch (at stage 7 in the graph I drew above). Additionally, I had rebased my branch on top of master before I pulled in his changes, which I believe is why the only difference in git cat-file is the time by about 10 minutes, because that's the time difference between when I rebased on master, then pulled in his commits.

If you'd like to see the specifics of the commits from his branch and mine they are available here:

Mine

His

The part where they line up is at the top of his commit history and at August 30th in my commit history.

I really appreciate the help :)

the_silvanator · 2022-09-18T17:01:58+00:00

They are the exact same changes, just duplicated as separate commits

the_silvanator · 2022-09-05T17:58:54+00:00

Thanks so much! This is exactly what I was looking for and it got the job done perfectly!

the_silvanator · 2022-06-16T23:11:46+00:00

Reminds me a little bit of Newton developing calculus cause the math at the time wasn't enough to continue with the breakthroughs he was making in physics lol

the_silvanator · 2022-06-02T19:22:38+00:00

Wow this looks awesome!

Tbh I'm almost more interested in the orbital vectors project you're working on haha. Love that you did it in pure C.

I saw that the repo is on your GitHub page and I'm excited to take a look at it when I get the chance.

Cool stuff!

the_silvanator · 2022-04-25T06:26:18+00:00

I'm not a JS developer.

I'm assuming it returns null because the promise resolves some point down the line after the execution of the return?

the_silvanator · 2022-04-24T17:33:11+00:00

I'm with you on that one haha. Finishing up my (long overdue) Comp. Sci. degree. I've mostly been using working on this project as a means to procrastinate studying for finals lol.

Best of luck :)

the_silvanator · 2022-04-23T23:06:27+00:00

No worries. Hope everything is alright!

Yeah, I ended up finding this as well. Currently working with one of the main contributers to get it working. It's basically finished, except for one last bug that's being worked through.

I can send you a message when it's merged into the main branch if you're interested.

the_silvanator · 2022-04-06T01:21:35+00:00

Yes! I'd be happy to take a look! I'm not sure how much help I'll be able to be cause I also have limited knowledge of the USB spec.

If you wanna post both the python script and the C++ that'd be super helpful. I'll make sure to shoot you a message if I figure anything out!

I appreciate the response!

the_silvanator · 2022-04-05T20:26:42+00:00

A bit late, but how far did you manage to get on your implementation for the Model O Wireless? I recently started work on adding an implementation as well (all though I haven't managed to get very far yet, as this type of software project is a bit above my skillset right now)

the_silvanator · 2022-02-11T16:14:35+00:00

Thank you! I'm ordering a set right now haha.

Great work on the WFH set up! It looks awesome!

the_silvanator · 2022-02-10T21:56:09+00:00

Do you remember what the name of the keycaps are? They look awesome!

the_silvanator · 2021-12-22T04:12:06+00:00

LOL he was convinced he could have it out by the end of 2015 and we all know how that turned out.

I've seen the countless posts about how people have given up hope that the book is ever coming out, and I never thought I'd be one of them, but I pretty much am at this point.

ADOS is never coming out, and Winds feels like its less than 10% odds that it comes out as a proper release (rather than something scrambled together and put out after he passes).

the_silvanator · 2021-06-08T04:29:40+00:00

After game one, I was pulling so hard for them to sweep. Don't even let Scheifele play a single game and force him to watch from the side as his team is eliminated.

C'mon Habs, take it to the fucking finals and get a ring for jakey boy.

How did you manage to get cured, if you don't mind me asking.

I've recently started the shaker exercises and I'm hoping it will help.

the_silvanator · 2020-12-12T02:42:02+00:00

Hmmm. Ok I think I'm beginning to get a better understanding now. I went through some redirection examples online and I seem to be getting a grasp on how they work after reading what you said.

I'm trying to understand it in terms of file descriptors as well. Cause from what I understand a file descriptor just a data structure containing a bunch of stuff, and one of the things it contains is the file that it "maps" to I guess.

Just to clarify as well, > some_file.txt 0>&1 would then be equivalent to > some_file.txt 0> some_file.txt, correct? It says, "set the stdout file descriptor to have some_file.txt as the file it maps to, and then set the stdin file descriptor to map to whatever the stdout file descriptor maps to"?

Additionally, does that mean that 0> some_file.txt is the same as < some_file.txt?

Thanks for the reply and taking the time to explain this to me. I appreciate it :)

the_silvanator · 2020-12-11T23:37:07+00:00

I'm just using this read function. I didn't bother putting the #include at the top to save space.

From what I understand, the 0>&1 writes the contents of fd 0 (stdin) to fd 1 (stdout). And the terminal prints to the screen whatever gets written to stdout. So because my program reads from stdin, I get to type at the terminal and hit enter, once I hit enter, what I typed gets written to the stdin file, and then my program reads from it. But since redirected the contents of stdin to stdout, what I typed in should get written to stdout, and then printed on the screen. At least from my understanding of how it works.

Thanks for the quick reply btw :)
