Re:Building Ultra Long Range Toslink on Wednesday January 08, 2025 @10:25AM (#42635176)
I did basically this exact same thing at work a few years ago.

For time-correlating audio measurements around the office buildings I needed a analog reference signal in sync.

So I drew up a PCB design with a toslink in/out connector, and a connector for a SFP module and just a lvds driver in between. It worked straight away (more luck than skill) I could then re-use network fibers already run around the basement, and convert it to analog in the MDF rooms of each building, and run the analog signal up to the 3rd floor through existing RJ45 cables.

Re:Addressing Changes to PfSense Plus Home+Lab on Thursday October 26, 2023 @06:17AM (#38023740)
I've been using pfSense on 4 private sites for years by now. Luckily I've not upgraded from CE. I think what pisses people off is the rugpull of them pushing people to get a free upgraded license and then removing it soon after.

As for "but its free". I think its reasonable to expect the free offering to be promotional. I know I have bough Netgate HW and license for work because I was familiar with their free offering at home. But stuff like the recent move might make me reconsider.

Yeah, I think I can see the link to Mark Rober. Although not at all to the same degree. Maybe it's the way of "acting dumb" in order to progress the discovery process, but a face that they know full well (obviously) that he knows what's going on? Essentially talking down to the audience?

Not sure. My first attempt at phrasing it did not get my feeling across well.

Re:“perpetual motion” device is clever [video] on Thursday September 14, 2023 @04:08PM (#37514161)
This one is pretty good, but I usually steer clear of his videos. Topics are pretty on point for my interests, be he just seem... Too full of himself? I don't want to be mean in any way, but if someone agrees maybe they can put a finger on what it is
Re:Canonical LXD forked by former project leader stgraber on Friday August 04, 2023 @06:51AM (#36998111)
My use case is to let others use the HW I manage, not to have a known linux environment.

Either if someone wants to run something as an internal service (logging, ect) which should not depend on their desktop being online, or they need beefy HW.

Re:Canonical LXD forked by former project leader stgraber on Thursday August 03, 2023 @10:50AM (#36986744)
I've been a big advocate for LXD. Running multiple servers at work where I set up containers that I gave collegues access to and such. I find that the "VM's but not" approach quite nice.

I've since moved away completely, just before the recent moves by Canonicle. Most of if not all of my reasons to move away from LXD relate to Snap or other sides of Canonicle leadership.

Re:Driver Adventures for a 1999 Webcam on Friday April 28, 2023 @04:35PM (#35746772)
I have an old industrial thermal camera that takes pretty good pictures. But I don't have the xp software for it, and without a "known good capture" it's hard to reverse engineer and make it work on Linux.
Re:Driver Adventures for a 1999 Webcam on Friday April 28, 2023 @04:32PM (#35746745)
On a tangentant note, I've considered if it would be possible to gut the driver related parts (usb / Bluetooth subsystem ect) of linux and package it up to run as a userspace application in windows.

Then we could all use ps3 dualshock controllers wireless again on windows. It seems all the links to third party programs to make it work are virus infected.

Re:UK government to rip out its Hikvision cameras on Friday November 25, 2022 @06:32AM (#33741413)
I'd assume they were bridged, so you could either daisy-chain the cameras, or use it in-between the uplink and an AP. So you could it whereever you already have an AP without pulling new cables.
Re:Electric ferry uses a long extension cord [video] on Wednesday November 16, 2022 @04:13PM (#33630702)
Worth noting is, the subtitles said "The ferry uses, each day, about 150-200 kWh" whereas the speaker said "the ferry uses today between 150 and 200kW". I'm guessing Tom Scott had him clarify later, but the units, and what could be assumed to be a timeframe or not, is not the same.
Are they, technically, any different than APT repositories?

Don't get me wrong. I hate Snap much more than the next guy, but the idea of keeping a repository so you can go look for, and discover, stuff that is supposedly also vetted by someone is nice.

The issue is, when an app store is a monopoly and not standardized.

APT repositories is, in my eyes, an example of "the good" type of app store.

Re:Why we ignore thousands of daily car crashes on Wednesday July 27, 2022 @07:40AM (#32249274)
Might be.

But I'd think a Give Way sign should suffice in practice even if the intersection has poor visibility. Only if the intersection proves to cheat drivers in to thinking the visibility is not so bad (and hence drivers won't slow down enough) is a Stop sign needed?

It's the old "if it looks safe but isn't".

Re:GPSJam: Daily Maps of GPS Interference on Wednesday July 27, 2022 @04:10AM (#32248029)
I zoomed in on a red spot in the US and was surprised to see the city name "Uvalde" pop up. Not quite in the center of the spot, but any thoughts on if it might be related to the reason that a European like me knows that name?
Re:Why we ignore thousands of daily car crashes on Friday July 22, 2022 @04:53AM (#32189965)
I've been told by driving instructors that the rule of thumb for putting up octagon STOP signs here in Denmark is only when a serious accident has occurred.

I can't find a source for it, but they are definitely rarer than most other places, and I feel like they are taken more serious because of it.

Re:How does a USB keyboard work? (2021) [video] on Saturday July 02, 2022 @07:47PM (#31963593)
Def. agree on this one.

I'm reminded of the closure viewers of the YouTuber Bosnian Bill got about his disappearance, by Lock Picking Lawyer doing an explanation video: https://www.youtube.com/watch?v=7ASQQboFg98

But I do also understand not all creators have a relationship with another creator which as much overlap of audience that it is possible.

Re:DNS Toys on Saturday June 11, 2022 @12:42PM (#31705860)
I can see the IP echo command be useful to verify if DNS traffic is routed differently than other traffic on a corporate network. Assuming outbound port 53 is not blocked completely on the network that is.

Re:USB Cheat Sheet on Thursday May 05, 2022 @01:35PM (#31276282)
My older Logitech C920 has an on-board H.264 encoder. Newer revisions of the same model does not.

I haven't figured out why they chose to remove it, but your point about licensing cost combined with them not advertising it much as a feature, and most of their competitors not including "proper" video encoding might explain it.

Edit: Found an official explanation here: https://www.logitech.com/en-us/video-collaboration/resources... TLDR, they figure most computers at that point had HW encoders.

Yes. And I hate that so so much.

I inherited an older Moccamaster, which does not have the timeout, and the newer one went straight to storage. Unfortunately the old button without a timer is not sold as a spare anymore, or I would have "downgraded" the newer machine.

Re:Ask HN: Why can't I host my own email? on Wednesday April 27, 2022 @11:55AM (#31181602)
I was a little discouraged after reading previous threads here, but decided to give it a try anyway.

I tried mailinabox and mailcow which didn’t work out, but mailu did.

Final setup is a pfSense vm on vultr, VPN back to my local pfSense box (with snort filtering) and mailu in an LXD container. Mailu guides you through setting up various dns records which helped me a lot.

In healthcare in my part of Europe, it is a requirement to log every access to patient journals.

And if a nurse, doctor or similar access a journal they most likely have no reason to, it can get flagged for investigation.

I payed for Rocket League quite a while back, as it had Linux support. But then they removed it. Ofc. I couldn't get my money back from Steam, and admittedly its not their fault but still.
Re:Minimodem – general-purpose software audio FSK modem on Saturday April 02, 2022 @09:35PM (#30893386)
I've had the "pleasure" of trying to transmit data / timecodes through active speakers with a lot of signal processing.

I don't imagine any QAM-like stuff working. FSK does, but the transitions get a little wonky, and the different frequencies will often have different phase shifts. ASK modulation should work, but haven't gone there yet.

But its interesting. I know a thing or two (literary) about encoding in the radio spectrum, but none of the encodings I've found deals with systems that are so un-lineary.

Re:UniFi Network Application 6.5.54 on Sunday December 12, 2021 @06:32PM (#29534821)
Updates are usually pretty easy. I manage 4 controllers at home, and 2 at work.

All hosted on debian.

I've had just one update go bad, so I do do the recommended backup/export beforehand.

That said, I don't trust Ubiquity much anymore. Use Unifi in QA setups so we are prone to hit cornercases, but they exists.

I still buy their gear as there is no competitors in the price range.

Re:What if there were no ad blockers? on Monday September 27, 2021 @03:31PM (#28675024)
It seems that there is such regulation in place, in the US at least. But regulation regards average loudness throughout the ad, so you can blast away if you compensate with silence.

I don't normally really like the YouTube channel Cheddar, but they recently had a video on this topic: https://www.youtube.com/watch?v=tmydvmxWUsE

Apparently its FCC regulation (I'm not in the US), and the FCC cannot create legislation for streaming services so they are currently free to do as they wish.

Apart from legal protection, I’ve found that if you are behind a crappy ISP router, bundling a bunch of Torrent connections in one VPN connection can prevent the router from becoming unstable.
Re:Experiments on a $50 DIY air purifier (2020) on Thursday September 02, 2021 @02:34PM (#28395662)
I had considered something similar, but recently I found that Ikea has started selling air purifiers and sensors for very reasonable money. They even sell an activated carbon filter that you can add.

Ikea FÖRNUFTIG: https://www.ikea.com/us/en/p/foernuftig-air-purifier-white-5...

I seems the Mach-E is the most sold model across the board, not just among Mustangs based on this article.

Fun fact: I just got back from Norway, and saw a Mach-E a week ago. Seen as it was apparently just released there "weeks ago", it must have been one of the first in the country.

Re:Live Starlink Satellite Map on Tuesday July 27, 2021 @10:58PM (#27979848)
Glad to hear about the the plans for polar orbit. I do volunteer work in Danish version of FEMA and have gotten more involved in our satellite internet solutions. Our biggest challenge is coverage over Greenland, as geostationary satellites are not visible over the horizon. Iridium has coverage, but it’s slow and bulky. We’re awaiting gear to test Starkink, I believe.
