My favourite ones are these ones from Sengled: https://a.co/d/9UPGMTZ

I'm in the USA so these are US-style ones. They support 1800W (which is the max for standard US outlets), use Zigbee, and are ETL certified.

Thanks for the explanation!

I still call it Twitter because their emails are still branded as Twitter. I don't actually use it any more but I do get so much spam through DMs that I'm considering deleting my account. I'm mostly holding it just so nobody squats on my username.

Websites don't have an actual check for a legit email.

Some do. You can connect to an SMTP server and pretend to send an email (send the EHLO, MAIL FROM, and RCPT TO commands, but don't actually send any content). A lot of servers will immediately reject as soon as you provide an invalid recipient email address.

Of course, that doesn't work for any domains with a catchall address (where every address at a domain goes to one mailbox), and some SMTP servers don't reject the email until later (or even just silently ignore emails to invalid addresses) in order to avoid enumeration attacks.

Do you mean in mixed language documents? Can't you tell it that parts of the document are in a different language? You could do that in Microsoft Word 25 years ago - Word lets you set the default language for a document, but you can change it per paragraph.

I'm using a UPS now so I'll get rid of the smart plug. I've been using it for three years and haven't had issues with it cycling though.

Good point. I am using a UPS now so I'll get rid of the smart plug.

I don't know anything about this company, but fiber is almost always better than cable. Lower latency, more reliable, and it's usually symmetric (upload speed is the same as download speed).

must be doing some construction on my street because they made survey marks on my property and painted where the gas line and water lines are. Could this be because they are putting in the fiber cables?

It's possible! Those marks means that some sort of digging/excavation is happening nearby. The company that wants to do the work calls a "dial before you dig" service (811 in the USA) and all the utility companies come out and mark their lines.

A while back, I saw a story in the Home Assistant Facebook group about someone's child saying "Hey Google, turn on everything" and it messing things up. I was telling the story to my wife and forgot to replace "Hey Google" with something Google wouldn't pick up on. Oops. It heard my "turn on everything" and chaos ensued. I have some Zigbee alarms that all started sounding. It enabled several different scenes and ran several scripts. All TVs turned on. My Xbox and Nvidia Shield were fighting for control of the TV (there's some issue with HDMI-CEC that I haven't figured out where if both are on, they get stuck in a loop changing the TV input between HDMI2 and HDMI3 about once per second).

Don't do that. "Turn off everything" is bad too. I ~~have~~ used to have my server rack plugged into a smart plug to measure power usage, and "turn off everything" turns that off. I want to figure out how to disable these two voice commands.

KDE still has some of the most popular effects built-in, including wobbly windows, desktop cube, magic lamp when minimizing/maximizing, blurring semitransparent windows, "exploding" windows when you close them. They're built in with no extra software required - just go to the "Desktop Effects" settings.

I usually use HTTPS, because a lot of web features only work over HTTPS.

You can use Let's Encrypt DNS challenges to get real TLS certificates for internal hosts, instead of having to use your own CA or self-signed certificates.

Tailscale has several NAT bypass / hole punching methods for double NAT (including CGNAT) and symmetric NAT, but they don't work in 100% of cases. https://tailscale.com/blog/how-nat-traversal-works

IPv6 is definitely a good solution since then you don't have to deal with NAT at all. IPv6 is pretty easily doable in the USA (at long as you're not using Starlink) but can be harder in other countries that don't have as robust IPv6 infrastructure.

 

I noticed that Spectacle has an option to upload to Imgur and Nextcloud. Is there a way to allow it to upload to an SFTP server?

Ideally I'd like for it to upload the file via SFTP then put the URL on my clipboard, which is what I do with ShareX on Windows.

 

I love Sentry, but it's very heavy. It runs close to 50 Docker containers, some of which use more than 1GB RAM each. I'm running it on a VPS with 10GB RAM and it barely fits on there. They used to say 8GB RAM is required but bumped it to 16GB RAM after I started using it.

It's built for large-scale deployments and has a nice scalable enterprise-ready design using things like Apache Kafka, but I just don't need that since all I'm using it for is tracking bugs in some relatively small C# and JavaScript projects, which may amount to a few hundred events per week if that. I don't use any of the fancier features in Sentry, like the live session recording / replay or the performance analytics.

I could move it to one of my 16GB or 24GB RAM systems, but instead I'm looking to evaluate some lighter-weight systems to replace it. What I need is:

  • Support for C# and JavaScript, including mapping stack traces to original source code using debug symbols for C# and source maps for JavaScript.
    • Ideally supports React component stack traces in JS.
  • Automatically group the same bugs together, if multiple people hit the same issue
    • See how many users are affected by a bug
  • Ignore particular errors
  • Mark a bug as "fixed in next release" and reopen it if it's logged again in a new release
  • Associate bugs with GitHub issues
  • Ideally supports login via OpenID Connect

Any suggestions?

Thanks!

Both systems have C-states enabled in the BIOS.

I have a few questions I'm hoping someone can help with:

  • Why does the older system show more C-states in the right-most "CPU(OS)" column?
  • What does it mean when they're suffixed with "_ACPI" like in the output from the new system?
  • How do I debug the new system not hitting any CPU package C-states?

I can't find any documentation about this, neither on the man page nor on Intel's site (the official powertop URL https://01.org/powertop doesn't go anywhere useful any more).

Thanks!

 

Google Analytics is broken on a bunch of my sites thanks to the GA4 migration. Since I have to update everything anyways, I'm looking at the possibility of replacing Google Analytics with something I self-host that's more privacy-focused.

I've tried Plausible, Umami and Swetrix (the latter of which I like the most). They're all very lightweight and most are pretty efficient due to their use of a column-oriented database (Clickhouse) for storing the analytics data - makes way more sense than a row-oriented database like MySQL for this use case.

However, these systems are all cookie-less. This is usually fine, however one of my sites is commonly used in schools on their computers. Cookieless analytics works by tracking sessions based on IP address and user-agent, so in places like schools with one external IP and the same browser on every computer, it just looks like one user in the analytics. I'd like to know the actual number of users.

I'm looking for a similarly lightweight analytics system that does use cookies (first-party cookies only) to handle this particular use case. Does anyone know of one?

Thanks!

Edit: it doesn't have to actually be a cookie - just being able to explicitly specify a session ID instead of inferring one based on IP and user-agent would suffice.

 

I'm replacing an SFF PC (HP ProDesk 600 G5 SFF) I'm using as a server with a larger one that'll function as a server and a NAS, and all I want is a case that would have been commonplace 10-15 years ago:

  • Fits an ATX motherboard.
  • Fits at least 4-5 hard drives.
  • Is okay sitting on its side instead of upright (or even better, is built to be horizontal) since it'll be sitting on a wire shelving unit (replacing the SFF PC here: https://upvote.au/post/11946)
  • No glass side panel, since it'll be sitting horizontally.
  • Ideally space for a fan on the left panel

It seems like cases like this are hard to find these days. The two I see recommended are the Fractal Design Define R5 and the Cooler Master N400, both of which are quite old. The Streacom F12C was really nice but it's long gone now, having been discontinued many years ago.

Unfortunately I don't have enough depth for a full-depth rackmount server; I've got a very shallow rack just for networking equipment.

Does anyone have recommendations for any cases that fit these requirements?

My desktop PC has a Fractal Design Define R4 that I bought close to 10 years ago... I'm tempted to just buy a new case for it and repurpose the Define R4 for the server.

 

Sorry for the long post. tl;dr: I've already got a small home server and need more storage. Do I replace an existing server with one that has more hard drive bays, or do I get a separate NAS device?


I've got some storage VPSes "in the cloud":

  • 10TB disk / 2GB RAM with HostHatch in LA
  • 100GB NVMe / 16GB RAM with HostHatch in LA
  • 3.5TB disk / 2GB RAM with Servarica in Canada

The 10TB VPS has various files on it - offsite storage of alert clips from my cameras, photos, music (which I use with Plex on the NVMe VPS via NFS), other miscellaneous files (using Seafile), backups from all my other VPSes, etc. The 3.5TB one is for a backup of the most important files from that.

The issue I have with the VPSes is that since they're shared servers, there's limits in terms of how much CPU I can use. For example, I want to run PhotoStructure for all my photos, but it needs to analyze all the files initially. I limit Plex to maximum 50% of one CPU, but limiting things like PhotoStructure would make them way slower.

I've had these for a few years. I got them when I had an apartment with no space for a NAS, expensive power, and unreliable Comcast internet. Times change... Now I've got a house with space for home servers, solar panels so running a server is "free", and 10Gbps symmetric internet thanks to a local ISP, Sonic.

Currently, at home I've got one server: A HP ProDesk SFF PC with a Core i5-9500, 32GB RAM, 1TB NVMe, and a single 14TB WD Purple Pro drive. It records my security cameras (using Blue Iris) and runs home automation stuff (Home Assistant, etc). It pulls around 41 watts with its regular load: 3 VMs, ~12% CPU usage, constant ~34Mbps traffic from the security cameras, all being written to disk.

So, I want to move a lot of these files from the 10TB VPS into my house. 10TB is a good amount of space for me, maybe in RAID5 or whatever is recommended instead these days. I'd keep the 10TB VPS for offsite backups and camera alerts, and cancel the other two.

Trying to work out the best approach:

  1. Buy a NAS. Something like a QNAP TS-464 or Synology DS923+. Ideally 10GbE since my network and internet connection are both 10Gbps.
  2. Replace my current server with a bigger one. I'm happy with my current one; all I really need is something with more hard drive bays. The SFF PC only has a single drive bay, its motherboard only has a single 6Gbps SATA port, and the only PCIe slots are taken by a 10Gbps network adapter and a Google Coral TPU.
  3. Build a NAS PC and use it alongside my current server. TrueNAS seems interesting now that they have a Linux version (TrueNAS Scale). Unraid looks nice too.

Any thoughts? I'm leaning towards option 2 since it'll use less space and power compared to having two separate systems, but maybe I should keep security camera stuff separate? Not sure.

 

I have a 10Gbps internet connection. On a system with a 10Gbps Ethernet card, I can get ~8Gbps down and ~6Gbps up:

I'd expect this to easily max out a 2.5Gbps network connection. However, while the upload is maxed (or close to it), I can only ever get ~1.0 to 1.5Gbps down:

Both tests were performed on the same system. The only difference is that the first one uses a TRENDnet 10Gbps PCIe network card (which uses an Aquantia AQC107 chipset) whereas the second one uses the onboard NIC on my motherboard (Intel I225-V chipset).

This is consistent across two devices that have 10Gbps ports and two devices that have 2.5Gbps ports.

I'm using an AdTran 622v ONT provided by my internet provider, a TP-Link ER8411 router, and a MikroTik CRS312-4C+8XG-RM switch. I'm using CAT6 cabling, except for the connection between the router and the switch which uses an SFP+ DAC cable.

I haven't been able to figure it out. The 'slower' speeds are still great, I just don't understand why it can't achieve more than 1.5Gbps down over a 2.5Gbps network connection.

Any ideas?

I couldn't find a "Home Networking" community, so this seemed like the best place to post :)

My house has this small closet in the hallway and thought it'd make a perfect place to put networking equipment. I got an electrician to install power outlets in it, ran some CAT6 myself (through the wall, down into the crawlspace, to several rooms), and now I finally have a proper networking setup that isn't just cables running across the floor.

The rack is a basic StarTech two-post rack (https://www.amazon.com/gp/product/B001U14MO8/) and the shelving unit is an AmazonBasics one that ended up perfectly fitting the space (https://www.amazon.com/gp/product/B09W2X5Y8F/).

In the rack, from top to bottom (prices in US dollars):

  • TP-Link ER8411 10Gbps router. My main complaint about it is that the eight 'RJ45' ports are all Gigabit, and there's only two 10Gbps ports (one SFP+ for WAN, and one SFP+ for LAN). It can definitely reach 10Gbps NAT throughput though. $350
  • Wiitek SFP+ to RJ45 module for connecting Sonic's ONT (which only has an RJ45 port), and 10Gtek SFP+ DAC cable to connect router to switch.
  • MikroTik CRS312-4C+8XG-RM managed switch (runs RouterOS). 12 x 10Gbps ports. I bought it online from Europe, so it ended up being ~$520 all-in, including shipping.
  • Cable Matters 24-port keystone patch panel.
  • TP-Link TL-SG1218MPE 16-port Gigabit PoE switch. 250 W PoE power budget. Used for security cameras - three cameras installed so far.
  • Tripp Lite 14 outlet PDU.

Other stuff:

  • AdTran 622v ONT provided by my internet provider (Sonic), mounted to the wall.
  • HP ProDesk 600 G5 SFF PC with Core i5-9500. Using it for a home server running Home Assistant, Blue Iris, Node-RED, Zigbee2MQTT, and a few other things. Bought it off eBay for $200.
    • Sonoff Zigbee dongle plugged in to the front USB port
  • (next to the PC) Raspberry Pi 4B with SATA SSD plugged in to it. Not doing anything at the moment, as I migrated everything to the PC.
  • (not pictured) Wireless access point is just a basic Netgear one I bought from Costco a few years ago. It's sitting on the top shelf. I'm going to replace it with a TP-Link Omada ceiling-mounted one once their wifi 7 access points have been released.

I just created a Lemmy server at https://upvote.au/ for my personal use. I created a test community with a test post, but searching for it in Mastodon doesn't work. I tried searching for both @dan@upvote.au and @[!dan@upvote.au](/c/dan@upvote.au). I see the requests in the Nginx log:

172.19.0.5 - - [13/Jun/2023:22:57:06 -0700] "GET /c/test HTTP/1.1" 200 10033 "-" "http.rb/5.1.1 (Mastodon/4.1.2; +https://toot.d.sb/)"

However, no results appear in Mastodon.

Any ideas?
