I’ve been getting a lot of 504 timeouts when opening posts.
- Comment on The Size of Adobe Reader Installers Through The Years 1 day ago:
It’s been ages since I’ve used Adobe Reader. I typically use Okular or Xreader. They are both tiny compared to Adobe’s bloatware.
- Comment on USB PD for older device 1 day ago:
It must be the PD trigger chip that does that then. With every PD trigger module I’ve used, I get a lower voltage if the requested one is not supported. It doesn’t stay at 5V unless that’s all the power supply supports.
- Comment on What are the most useful things you've printed? 1 day ago:
The connectors are held in place with a roll pin that goes through the hole. They fit tightly in the panel mount. The pin just keeps them from pushing back out.
- Comment on What are the most useful things you've printed? 2 days ago:
Probably my panel mounts for Anderson PowerPole connectors. I use them just about everywhere that I need a 12V DC power outlet.
- Comment on USB PD for older device 3 days ago:
There are plenty of chargers that support a fixed 12V output without needing PPS. Just check the specs before buying one.
If you use a CH224K USB PD trigger chip, it has a power good pin. It will go low if the power supply is providing the requested voltage. You can use it with a MOSFET and driver circuit to switch the output on only when it gets the correct voltage.
- Comment on USB PD for older device 3 days ago:
12V support is optional in USB PD. If the power supply doesn’t support it, you will get 9V instead. PPS support is even less common.
- Comment on Solar panels in space could cut Europe's renewable energy needs by 80% 4 days ago:
Fusion would be much more practical than beaming back power from space. I think the chance of seeing either of those by 2050 is about 0%.
- Comment on need help on old CRT tv 6 days ago:
Some old tvs and depending on the electrical circuit they are plugged in dont like when high powered devices are running.
It’s not really an issue with high powered devices, it’s an issue with brushed motors that arc and produce loads of RFI.
- Comment on Dead simple document host? 6 days ago:
A web server with directory listing enabled would work fine for that.
- Comment on SpaceX says states should dump fiber plans, give all grant money to Starlink 1 week ago:
Starlink has been much better than every other option where I am, but I will switch to fiber as soon as it gets here.
They’ve been promising fiber here for over a decade, but I can finally see them installing it two miles up the road now. Hopefully it will actually be available sometime soon.
- Comment on SpaceX says states should dump fiber plans, give all grant money to Starlink 1 week ago:
My average latency on Starlink over the past year is 32 ms. It varies throughout the day from around 20 to 40 ms.
If you are getting 90ms on fiber, you are either pinging a server that’s a long ways away or something is very wrong.
- Comment on Chrome VPN Extension With 100k Installs Screenshots All Sites Users Visit 1 week ago:
Most people don’t need to run everything though a VPN. That just slows everything down. You would normally only use them to access resources on a private LAN such as when working from home or accessing your self hosted services when away from home.
- Comment on Why It's OK to Block Ads (2015) 1 week ago:
It’s my network. I control what does or does not go through it.
- Comment on IPv6 & Opnsense & Not Exposing Machine-Specific IPv6s to Corpos 1 week ago:
The setting to look for is “IPv6 privacy extensions”. That prevents your IP address from being tied to your MAC address. It should be enabled by default on any modern operating system. It can be set to either permanent or temporary.
IPv6 allows you to have multiple addresses on the same device. You can have a temporary address for all outbound connections and a fixed address for inbound connections.
- Comment on Calibrating my E-steps ended up giving me nearly pixel-perfect prints (Creality K1) 1 week ago:
Is that hotend and nozzle actually able to keep up with the 48mm³/s flow rate needed to print at 600mm/s with 0.2mm layers?
I’ve been thinking about upgrading mine. The stock hotend can only do about 20-25mm³/s at reasonable temperatures.
- Comment on I had no idea it was possible to create a working floppy disk from scratch, and neither did this YouTuber until they broke out their engineering chops 1 week ago:
It didn’t work though. He wasn’t able to actually store any useful data on it.
- Comment on High-severity WinRAR 0-day exploited for weeks by 2 groups 2 weeks ago:
WinRAR still exists? I think it’s been a couple decades since I last used it.
- Comment on My new laptop chip has an 'AI' processor in it, and it's a complete waste of space 2 weeks ago:
You can use object detection to send an alert if there is a person in your yard or if a car pulls into your driveway. It avoids the frequent false alerts you get with normal motion detection.
- Comment on My new laptop chip has an 'AI' processor in it, and it's a complete waste of space 2 weeks ago:
It would be nice if Frigate supported the NPU in AMD CPUs. Then it could be used for object detection with CCTV cameras.
- Comment on Is my domain "burnt" when hosting my first Fediverse technology? 2 weeks ago:
You can put each service on a separate subdomain and they will work fine.
- Comment on How do I get started designing and making and/or acquiring my own pcb? 2 weeks ago:
On single sided PCBs, you can do a toner transfer on the component side for a silkscreen. You can apply solder mask too, but it’s a rather messy process.
- Comment on How do I get started designing and making and/or acquiring my own pcb? 2 weeks ago:
Read the documentation. There are tools and features that will make some stuff a lot easier if you know about them.
Get familiar with creating your own symbols and footprints. No CAD program will have all the parts you need.
Don’t modify the libraries that come with KiCAD. Those changes will be lost when you update KiCAD. If you need to modify a part, create a new library and copy the part into it.
Double check footprints before you make the board. It’s no fun finding out the part doesn’t fit when you go to solder it.
Set the design rules to match the capabilities of the PCB manufacturer and run a design rule check before making the board. Don’t use the smallest traces and spaces they support if you don’t have to. - Comment on How do I get started designing and making and/or acquiring my own pcb? 2 weeks ago:
I would recommend using KiCAD for PCB design. You can either export the gerber files and send them to a PCB fab or you can etch or mill the board at home.
- Comment on HBO Max’s Password-Sharing Crackdown Will Start in Earnest in September 2 weeks ago:
Add the RSS feed for /r/OpenSignups to your feed reader. Wait for a good tracker to open up. TorrentLeech was open last week. It will probably be quite a while until they open again, but that’s a good tracker that’s easy to get onto.
The other option is to interview for MyAnonaMouse or Redacted. They have invite forums that you can use to sign up for other trackers once you get access to it.
- Comment on AOL will end dial-up internet service in September, 34 years after it's debut — AOL Shield Browser and AOL Dialer software will be shuttered on the same day 2 weeks ago:
Kuiper and Guowang are currently launching satellites. It will probably be a few years before they are operational though.
- Comment on Router suggestions for a complete noob 2 weeks ago:
Most routers don’t support open source firmware. If you want privacy and firmware updates, it needs to be supported by OpenWRT.
- Comment on 3 weeks ago:
A switch mode LED driver can be made very tiny with as few as 4 components. Battery protection and a single cell battery charger can also be very simple.
- Comment on Adobe was sued today in another class action about its subscription practices. Plaintiffs claim Adobe intentionally misleads consumers 3 weeks ago:
There is a donate link on their website.
- Comment on This 50% recycled glass solar panel performs like brand new 3 weeks ago:
Of course there’s no difference. Glass is one of the most recyclable materials there is.
