Kroger’s plans to roll out facial recognition at its grocery stores is attracting criticism from lawmakers, who warn it could lead to surge pricing and put customers’ personal data at risk by dan in c/technology@lemmy.world
[-] dan@upvote.au 130 points 1 month ago

“To be clear, Kroger does not and has never engaged in ‘surge pricing,’” the statement said. “Any test of electronic shelf tags is designed to lower prices for more customers where it matters most.”

Isn't that the same thing? It doesn't matter if you raise prices on demand or lower them, the outcome is the same - different pricing at different times.

Cars Are Rolling Computers Now. So What Happens When They Stop Getting Updates? by dan in c/technology@lemmy.world
[-] dan@upvote.au 175 points 4 months ago

I hate these proprietary systems because companies have very bad track records in terms of maintenance, since they'd rather you buy a newer product.

In 2022, the automaker told drivers of the affected cars, some only three years old, that a technical solution was delayed by the pandemic. Now, more than two years later, those drivers still don’t have access to telematics services. [...] Vehicles from Hyundai and Nissan, some as late as model year 2019, also lost some features after 2022’s 3G sunset.

In a country with good consumer rights, this would be a valid reason to return it and get a replacement or refund: It's no longer offering functionality that was advertised and that you paid for as part of the purchase price.

The new Chinese owner of the popular Polyfill JS project injects malware into more than 100 thousand sites by dan in c/technology@lemmy.world

My favourite part is that the developers that currently own it said:

Someone has maliciously defamed us. We have no supply chain risks because all content is statically cached

https://github.com/polyfillpolyfill/polyfill-service/issues/2890#issuecomment-2191461961

Completely missing the point that they are the supply chain risk, and the fact that malicious code was already detected in their system (to the point where Google started blocking ads for sites that loaded polyfill .io scripts.

We don't even know who they are - the repo is owned by an anonymous account called "polyfillpolyfill", and that comment comes from another anonymous account "polyfillcust".

Spectacle export to SFTP? (upvote.au)

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.

[-] dan@upvote.au 175 points 8 months ago* (last edited 8 months ago)

and you shouldn't be using any of those, since the order can and will change. The numbers are based on the order the devices and device drivers are initialized in, not based on physical location in the system. The modern approach (assuming you're using udev) is to use the symlinks in /dev/disk/by-id/ or /dev/disk/by-uuid/ instead, since both are consistent across reboots (and by-id should be consistent across reinstalls, assuming the same partitioning scheme on the same physical drives)

This is also why Ethernet devices now have names like enp0s3 - the numbers are based on physical location on the bus. The old eth0, eth1, etc. could swap positions between Linux upgrades (or even between reboots) since they were also just the order the drivers were initialized in.

It's hard because Mozilla need money to survive, and the world needs Mozilla, but it's been hard for them to find a stable source of funding. Mozilla relying on their main competitor (Google) for most of their income is a massive risk. I can understand why they're trying approaches like this, even if the users don't like it.

Does anyone here have a suggestion as to a better way for them to increase their income?

Lighter weight replacements for Sentry bug logging (upvote.au)
submitted 10 months ago* (last edited 10 months ago) by dan@upvote.au to c/selfhosted@lemmy.world
6 comments fedilink

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!

Looking for simple analytics (similar to Plausible) that supports cookies (upvote.au)
submitted 1 year ago* (last edited 1 year ago) by dan@upvote.au to c/selfhosted@lemmy.world
13 comments fedilink

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.

ATX case with room for 5 hard drives (upvote.au)
submitted 1 year ago by dan@upvote.au to c/selfhosted@lemmy.world
25 comments fedilink

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.

NAS vs larger server (upvote.au)
submitted 1 year ago by dan@upvote.au to c/selfhosted@lemmy.world
27 comments fedilink

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.

My 10Gbps Home Networking Closet (d.ls)
submitted 1 year ago* (last edited 1 year ago) by dan@upvote.au to c/selfhosted@lemmy.world
34 comments fedilink

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.
