It's pre terminated pure copper direct burial cat6 from Amazon. I don't have access to a real tester, but my cisco switch has some built in test capability and I'm not sure I fully understand the results, but it's assessment of the cable length is pretty close and, more importantly, it shows all the pairs are the same as each other. I think that if there was some damage to the cable, it's unlikely that it would affect all the pairs in exactly the same way. I have other weird grounding issues - like 20V between neutral and ground, even though it's a new house and they're properly bonded at the service entry. I had a really old transformer on the street feeding the two buildings and the power company recently replaced it - I was disappointed when this didn't resolve all my issues.

I guess that's what I haven't figured out yet - it's about 200' and I don't have 200' of wire laying around. I'm thinking of making dummy terminations for each end of my cat6 cable and stripping each of the pairs and twisting them together so it works as a single conductor and using that to measure.

It's a 200' cable and the buildings each have their own connection to the power company. I suspect that the earth potential of the two buildings is quite different - I just have not figured out a way to measure it yet and not sure if there's anything I can do to fix it even if I do confirm it.

I already have a pair of Ubiquiti airMax GigaBeams left over from a different project and agree - they perform incredibly well. I didn't even bother aligning mine as they did 800Mbit/s just pointed in the right general direction. A trench was being dug to the studio for another reason and cable is relatively cheap so I figured I'd drop one in. Hasn't turned out as well as I hoped. I will setup the GigaBeams one day - but the cable does occasionally sync at 1Gbps and I'm hoping that one day it just stays there :-)

As someone who grew up with 10Base2 and 10BaseT, and thought 100Mbps was amazing - it still surprises me every time I'm reminded how slow it is now. I buried a cat6 cable out to my wife's studio and due to (I assume) some grounding issues it only syncs at 100Mbps - it works for general browsing etc., but every time we try to move some data it's arggghhh.

Here's a short video showing Jerboa first and then Interstellar. It's hard to predict how this will play on your phone, but when I watch this full screen on my phone it makes both look worse than they actually are. In reality, Jerboa scrolls with zero jitter and Interstellar scrolls like Jerboa in the video.

I've just installed Interstellar and think it looks great. I've been using Jerboa and browser for Lemmy. The announcement of piefed.ca suggested this as a Piefed app, so here I am.

First impression is that I think I'm going to like it a lot - almost feels like RiF that I've been missing for some time. But - I'm finding scrolling really unpleasant - it's really jumpy, or jittery and hard to look at. I'm finding it so bad that I'm surprised it's not mentioned here or on GitHub, and I'm wondering if it's just me?

I know you're having a joke, but Barron's taller than either of them - he's 6'7" or 6'9" depending on who you ask.

Me too, but only because I very strongly lean toward "god was created by man" rather than the other way around.

I hate organised religion too, and I get what you're saying but, like it or not, the pope is a world leader with a lot of influence - if he can use that influence to reduce the fighting (even if with selfish motives) then that's a good thing.

I totally agree, and I just switched from Windows to Linux for my desktop, but this isn't on Microsoft - it's sanctions on the ICC by the fascist regime running the country where they (Microsoft) are based in support of the fascist regime destroying Gaza. (I know I'm probably over simplifying it, but that's my take on the article)

It's a little different, but works. I was in business operations for the last 20 years and relatively proficient with Excel. I'm retired now but I'm treasurer for a small community non profit organization. I recently switched to Linux desktop and found Calc handled my sheets with pivots etc. just fine. About the only thing I'm missing is End-Arrow to move to the last populated cell in a row or column, but not missing it so much that I've tried to figure out how to do it in Calc - yet.

 

Edit - I just went to the sync status page in the Windows client and hit "Retry All" on he failed objects again - and it worked! I have not changed anything since last time it failed - but for now I'm happy!

There's probably a lot of overlap between this community and Selfhosted@lemmy.world so some of you might recall my post from yesterday sharing some frustration about Nextcloud. Well today is Joplin's turn :-)

I've been using Joplin on Android for a little while now as a proof of concept - only a 6 notes so far, each only a page or so. One of my reasons for re-trying Nextcloud was because Joplin supports it as a sync method. After the discussion about Nextcloud yesterday I decided to try some of the suggested alternatives.

First I setup Syncthing and got that working so I have some folders syncing between Android, Linux and Windows. Then I setup Joplin to sync to filesystem - into one of the folders that Syncthing is managing. Joplin on Android sync'd everything to the filesystem, but when I tried to sync that filesystem to Joplin on Windows the attachments (photos) were missing from my notes. I can see the files (by id) in the .resource folder of the filesystem sync target but the Windows Joplin client won't pull them in.

I figured this multiple sync (Joplin <-> filesystem <-> Syncthing <-> filesystem <-> Joplin) might be an issue so I decided to try WebDAV. I configured a WebDAV folder my apache2 server, setup Joplin on Android to sync to WebDAV then went to the Windows Joplin, cleared the local data and setup WebDAV sync. Same thing - no photos in my notes. I can see the files are on the WebDAV server and there are no errors in the server logs so I guess the Windows client was able to pull them - but they don't show in the notes.

I tried searching and see several very similar issues on Discourse with no resolution.

Does this work for anyone else?

Edit - I just created a test note in the Windows client with an embedded image and this sync'd correctly to Android.

  • Joplin 3.2.13 (prod, win32)
  • Joplin Mobile 3.2.7 (prod, android)
 

I tried Nextcloud a while back and was not impressed - I had issues withe the speed of the Windows sync that were determined to be "normal" with no roadmap to getting fixed. I'm now planning to move off Windows desktop so that won't be an issue - so I thought I'd try again.

I went to nextcloud.com, clicked on Download-> Nextcloud server -> All-in-one -> Docker image - Setup AIO. This took me to the github README at Docker section. I'm already running docker for other things so I read the instructions, setup a new filesystem for my data directory and ran the suggested docker command with an appropriate "--env NEXTCLOUD_DATADIR=". I'm then left with a terminal running docker in the foreground - not a great way to run a background server but ok, I've been around for a while and can figure out how to make it autostart in the background ongoing. So I move on to the next step - open my browser at the appropriate URL and I'm presented with a simple page asking me to "Log in using your Nextcloud AIO passphrase:". I don't have a Nextcloud AIO passphrase and nothing I've read so far has mentioned it. When I search for it I get some results on how to reset it, but not much help. I could probably figure that out too, but after reading some more I found that Nextcloud requires a public hostname and can't work with a local name or IP address. I'm already running my home LAN with OpenVPN and access it from anywhere as "local" - I don't really want to create a new path into my home network just for Nextcloud.

I'm sorry - I know this sounds like a disgruntled rant and I guess it is. I just want to check that I'm not missing obvious things before I give up again. All I want is a simple file sync setup like onedrive but without the microsoft.

 

... or are notifications just really bad on Android?

For background, we've got an old, sick, dog and my wife often needs to get help from me urgently. I'm still running an old Pixel 4a - it worked really well for me until Google crippled the battery and even now it works well enough that I'm not tempted to upgrade.

My notifications always seem to be delayed - in batches. I have 3 buildings on my property and each has a Nest doorbell. Some days I can be walking around and I'll constantly hear ding, ding, ding as I walk past each doorbell. Other days I can walk around and hear nothing, and then I'll get 5-10 notifications all at once.

Today was a perfect example of why this is so frustrating - I'm sitting at my desk with my phone in front of me. It's plugged in an charging. My phone starts ringing and it's my wife upset that I have not responded to her messages. I go help her with the dog and come back to my phone and sure enough, 8 minutes ago there's a notification from Google Chat, 6 minutes ago there's a notification from Google Messages and 4 minutes ago there's the phone call. The Google Chat and Google Messages notifications never came through - until the phone call came in!

I've been through and made sure that all the battery optimisations are turned off for all the apps that I want instant notifications from - but that shouldn't have any impact here - my phone was plugged in.

Is this normal Android? (kinda rhetorical question - I've been running Android since my Nexus 4 and don't think this is normal but it feels like it's somehow the "new" normal)

I'm not running the stock Pixel launcher - does the launcher get involved in notification delivery at all?

 

I'm really disappointed with myself. I thought I would enjoy, and be good at, sharpening knives. I don't and I'm not! I have two Shapton water stones and I can get a nice edge on my chisels with a jig that maintains the angle for me, but I just can't get a good edge on a knife. I don't know if I'm not patient enough, if I just can't hold the angle well enough or what, but I give up.

My wife is, understandably, frustrated with a kitchen full of dull knives and bought one of those drag through carbide/ceramic sharpeners and I can't even make that work - I drag a blade through a few times, there is a pile of swarf in the sharpener, the blade looks sharp - but it's dull as dull, maybe even worse than before "sharpening".

We have a range of knives from grocery store mild steel, through decent consumer Mundial and Victorinox to one low end nice Global.

Appreciate any suggestions!

Some of you may recall my previous post about a ~20V potential between my electrical ground and my concrete slab. That's still not resolved - it's currently sitting just under 10V.

Today I have a new mystery - to me anyway..

I'm sitting at my desk and notice that I got a tingle from the outer shield/shell of a USB-C cable. I got my multi-meter and measured 65V from the cable to me with my bare feet on the slab! It drops to about 16V if I lift my feet off the floor. I immediately assumed the charging brick it's plugged into was faulty, but just in case I took a more measurements and found that the another similar charger has a similar offset, the "ground" part of a TRS cable plugged into an amplifier is similar, the accessible metal shield part of a USB-A port on an ASUS ChromeBox is similar. I assume that's not normal?

This is a new slab on grade build. Ground and neutral are properly bonded - I checked a few outlets and ground to neutral is ~0.3V.

Edit - I don't think there is any safety risk - I measured 0.3μA current.

 

I live in a small community at the end of a long line in Atlantic Canada. We get frequent power disruptions so I have installed a backup generator. I have a bit of a home lab, and don't like my server to lose power with no warning so I've recently installed a small UPS to keep it running in the gap between my power going out and the generator starting. The UPS logs data and lets me access it.

I'm wondering if I should be concerned about my input voltage. The blue line in the minimum for the hour, the amber is maximum for the hour. The zero period on the 8th of March was when I had the power turned off to do some work.

The default configuration for my UPS has it cut over to battery power at 88V, so it seems some significant variation is expected!

I tried searching my power company web site but they don't seem to publish anything about guaranteed, or even expected, supply voltage.

 

I'm very new to this. I have used Street Complete to do some little things over the last few months, but made my first manual edits yesterday.

I'm starting by fixing up the small community where I live. A lot of stuff has already been done by some automation using "NRCan-CanVec-7.0" data and it's really wrong for civic numbers. But, it matches the numbers in the "standard" layer in the maps. I'm happy to go around and manually draw houses and update civic numbers (I did say it's a small community) but the map is going to look confusing when the base layer shows conflicting numbers. How can I fix that?

 

I hope avoiding Amazon fits this community rules?

I need a few bits to resurrect an old PC. My Amazon cart is $68 with shipping - we're going to cancel Prime, but my wife is still working on downloading all her photos. Best I can do elsewhere is near double this PLUS shipping from 3 different suppliers and 2 of the suppliers are on eBay, which is also a US company.

I moved to Canada a few years ago from Australia where I had pccasegear, scorptec and others. It seems Canadians have become reliant on the US market and Amazon and we now have no competitive local retailers for this type of thing?

 

I've just had a new house built in Atlantic Canada. This morning I noticed a bit of a tingle from my coffee machine when I touched it with wet hands. The machine has a grounded (3 pin) plug and I checked - it has 0V between the parts I touched (the entire metal outer case) and the ground socket in the outlet. So, I got curious and did some more measurements. It turns out there is 20V AC (and about 300mV DC) between the ground in my outlets and me when I'm standing on my floor (sealed concrete slab) with bare feet.

I assume this isn't good?

I'll be calling the electrician that wired the house in the morning, but I'd appreciate any insights you might have.

 

I've just had a new house built in Atlantic Canada. It's not performing as well as I had hoped it would - I'm getting condensation on my windows and door handles and my power bill is higher than I expected.

I know I rushed things a bit with the build, and we were on a tight budget, but I (naively?) thought that following the building code would get me a "good" house.

I've done a little research and found that I have a very generic, builder basic level, air exchanger - a FanTech Flex100. Their own documentation even only lists the efficiency as "moderate". My initial reaction to this discovery is that air exchanger efficiency is critical - it's literally bringing in colder air than it really needs to - and I should look into upgrading as soon as I can afford it.

Does this make sense, or are there other factors I should consider first.

(I know there's lots of detail missing - I didn't want to put in too much effort for a question in what appears to be a dead community. Happy to elaborate as much as needed.)

 

So pissed off with google. I've had google phones since my Nexus 4. I'm not a power user by any means and I'm now only on my 4th phone since then - a Pixel 4a. It's perfect for me - nice and small so it fits in my pocket, headphone jack etc. and all day battery! For my usage pattern I never had to think about battery even on such an old phone - I'd just charge it on my nightstand each night and never give it a thought.

Since the recent update - it's now 09:26 and I'm already down to 50%.

I know they say it's for my safety, but I simply don't believe them. I can't afford a new phone now, don't live anywhere where I can get the battery replaced reasonably and it's out of stock where I've looked for a DIY replacement. I'm stuck with this.

Update - typing the paragraph above took me down to 48%
