It's doing something different, I was using to mount an AWS FSx for ZFS share on a beefy machine (1.2GB/s network throughput) and was getting less than 50MB/s throughput using docker to mount it, but getting the full 1.2GB/s when mounted outside and mapped to a volume in the container.

I found this to be extremely underperforming. If you plan on doing anything that requires high throughput, don't use the docker NFS operator.

That thing would be so fucking loud all the time.

And this is the problem with public companies and private equity. Number must go up.

Yes, and I also know that cats are more likely to carry it than squirrels, but I don't see the cops breaking down cat owners doors.

I love it when scientists who know something to be true in theory get to see practical experiments like this. The jubilation on thier faces.

This is such fucking bullshit, so you corner an animal, it bites you, then you shoot the animal because it bit you?

I hope you never own or work with animals.

Yeah, it's pretty good!

Yeah, sure, but with like 2k employees, they will only look if there are issues with me. Having worked in the IT industry for a long time, I've only once or twice had to dig into shit like that for HR and it was only when the person did something bad.

What are you using for your home automation and what are you running it on?

[–] [email protected] 4 points 6 days ago (2 children)

Unfortunately. But I also use my corpo AI accounts for personal stuff too, because it's immune to being used for training.

I use it all the time, to translate, explain, give guides, write code, do repetitive menial tasks, fix code, understand others code.

I get the hatred for it, but I use it almost every day.

I guess they're just going to end up being really good but heavily overpriced like the rest of the FormLabs products.

So I've worked in IT for around 18 years now and in that time I've worked for 2 gaming companies, I started my most recent a year ago, but I'm wondering if I should just jump ship for the tech industry again, I'm now waiting for the layoffs in our business unit. I'm an immigrant living on a work permit and losing my job will mean losing the life I've made for myself over the last 4 years, and that terrifies me.

I used to love the company I work for but now I'm wondering if it's worth it anymore.

 

Hi,

I'm looking for some help in a field that is super technical and I don't fully understand.

I'm planning on using a bunch of these seeed studio Esp modules for some home automation projects, especially because they have a lipo battery charger making it great for portable stuff.

The thing is the the ESP32s have U.FL SMD antenna connectors. Most of the antennas that you can buy with U.FL connections while are reasonably small, come with 50-150mm leads, which sort of makes the small size of the module a little less valid.

What I'd like to do is get a female U.FL SMD connector and make a small daugherboard with an 2.4GHz SMD antenna on it, for instance a Janson 2450AT42B100 or a Molex 479480001.

They go over the circuit board requirements quite thoroughly so I don't think designing it will be too difficult, but what I don't know is, they say that you need impedance matching on the circuit, and I see that there appears to be something that looks like it on the ESP circuit diagram, but I'm not actually sure if it is or not:

You can see it in the middle near the bottom of the diagram here: Seeeduino-XIAO-ESP32C3-SCH

So my questions are:

1: Is this a dumb idea, having a direct plug-on SMD antenna?

2: Is that an impedance matchning circuit between LNA_IN on the ESP chip and U.FL-R-SMT-1?

3: If I can't get a female U.FL SMD connector, would using one with a lead and shortening it to make the daughterboard able to be much closer to the connector affect anything? Do I need to ensure that the lead length matches the wavelength at all?

Edit: Found this SMD female U.FL, so they do exist.
