I’m completely unique, both AmIUnique and the CreepJS test highlighted my installed fonts and two webcams (one of them is actually a virtual redirect for my primary webcam, since the drivers are DirectShow-based)

Would be interesting to see how my linux laptop performs, tbf it might be unique too considering it’s a mbp 2012. I remember running into at least one website I visited on it showing much higher prices compared to when I revisited the same website later from my windows desktop…

By making something private, IMO you’re revoking its status as an inherent right, and restricting access to only those who can afford it.

IMO the primary issue with this specifically venture funded stuff is that it’ll undercut the competition for as long as possible, and then hike the prices once the competition has ceased to exist. When other recurring sources of funding are available, as it usually is with public services, this kind of thing is much less of an issue

The hospitals in my nearby city have their own BRT which is open to public use, and joined to the city’s ticketing system. It shuttles between them and various key locations, and is of course wholly subsidized for the intended users.

Despite being the only BRT here it pretty much goes everywhere it should, skipping the usual traffic, and as a result gets a lot of use.

If the users were limited to the regular transportation I think they would just all drive - while there are a lot of routes here they’re not entirely pleasant to use IMO and almost always get stuck in traffic

Treated worse than pirates: things like blu-ray media only being playable on the newest blu-ray players. If your old player has no update available, you’re essentially forced to purchase a new one

Viewed as second class citizens/criminals: IMO DRM is a big one here. Why install a rootkit on someone’s computer just to identify if they’re a real customer or not? I can somewhat understand if its an online game that needs to also take advantage of anticheat to detect cheaters (still crappy though) but assuming such a level of control over someone’s equipment in the off-chance that they’re a pirate seems a bit iffy. Especially when it does nothing to prevent piracy anyway.

On that last point - even worse when its online-only DRM for a single player game that you purchased for $50 or more. Even worse worse when it’s linked to an online account that can get banned erroneously, or service revoked in that region due to local law changes. Non-starter, I’ll just 🏴‍☠️ at that point if I really wanted the game.

Personally steam is the only exception for me: my games launch locally without an internet connection regardless of offline mode or not, and in-game bans don’t revoke access to your entire library. Steam also operates in a metric crap ton of regions, and to date I’m not aware of them pulling service (except in a certain country that apparently banned them recently)

The !electronics community would be a better fit for this post IMO

That said this looks interesting, and seems really competitively priced when compared to other similar thermal cameras like the Flir One Gen 3. This measures a very wide temperature range too, from -20°C to 400°C within ±2°C, whereas the Gen 3 tops out at 120°C.

The 80x62 resolution is OK for this application IMO, the Gen 3 is similar at 80x60.

I wouldn’t go recommending one of these to a “casual” user though, it’s very much a development product. Non-casual users could probably 3d print a case and get on just fine with the demo apps IMO, and for those users this would probably worth its weight in gold, given how expensive thermal imaging usually is.

Given how closely its priced to radar presence sensors like the Aqara FP2, and the inclusion of I2C for comms, I think this is going to have some appeal to DIY home automation enthusiasts too, especially if it gets supported by open source projects like ESPHome

Technical docs: www.waveshare.com/wiki/Thermal_Camera_HAT

Edit: I should also mention that there are much cheaper options on sites like AliExpress if you just want something cheap to use via usb-c - the advantages this sensor has are heavily dev focused IMO and might not make sense for most users (e.g. documentation, i2c comms, product integration support)

Yepp I agree lol, coverage about him/his companies gets old really fast…

Even worse when its stuff like laying off the one of his companies’ most profitable business units over a childish disagreement 🤦‍♂️ just to reverse the decision after reporters start spamming his antics everywhere, leading to more spam.

Feel like he likes to see his name in the news or something, very tiring IMO

IMO more accurate presence detection. Common sensors like PIR and cheaper doppler radar types can detect when there’s motion, but not if a user is present but not moving in the detection area (e.g. sleeping or sitting). There’s also open source projects that can track bluetooth wearables & phones to know who specifically is in a room, but these aren’t able to detect people with no devices, say guests and kids.

The preferred approach at the moment is a combination of sensors to cover motion and person detection separately, which comes at a cost, both on your pocket and the time needed to get it working suitably for your needs, or maybe one of the more expensive radar sensors like the FP2 that can detect where in a space is occupied with higher accuracy than more affordable alternatives

The thermal cam is roughly in the same price range as the FP2 - however since it has I2C, something cheap like an ESP8266 can be used to turn it into a WiFi based presence detection sensor. Something like an ESP32 could be used to turn it into a presence detector and wearable tracker, negating the need for another separate sensor entirely.

Something like this would probably be quite close to plug and play for someone DIY focused, and wouldn’t have the same problem as radar being able to see through walls to different areas, although this is somewhat solved by surrounding the rear of the sensor in foil with caveats.

I’m interested in how it performs outdoors in rain though, a lot of existing affordable sensors (except PIR) struggle a little in wet conditions, with doppler based ones not detecting anything

I recently setup a Meshtastic lora node and realized antennas are complicated… I never knew there were ones that are most resonant on specific frequencies and stuff, the importance of having the impedance close to 50ohms for best performance. And fake amazon ones that give you only 8cm of antenna wire inside a 37mm shaft 🤦‍♂️

That said, I am shocked that something the size of my thumb can communicate 1km through buildings, and uphill to the other side of my village on such low power. This radio stuff is really fascinating.

I had a similar stringing issue with PETG on my flsun Q5, where PLA was printing flawless without any strings whatsoever. Since your SR isn’t a bowden, that mostly rules out retraction distance IMO.

For me I narrowed it down to Z-hop: as the printer was lifting the nozzle slightly to move to another part of the print, molten filament oozed out - sticking to the print, and getting stringed across by the nozzle. I only noticed after recording the print (use at least 60fps to avoid the frame blurring you’ll get at 30> and watching what exactly was happening prior to the stringing. It took about 4 hours to get to that point 😭

If orcaslicer is based on Prusaslicer, wipe on retract with the initial distance set to 100% may not trigger a wipe. Try 70% or 80% instead. There’s another setting somewhere to force retraction when changing layers: enabling this will forcibly honor your wipe retraction preference when changing print layer.

I think you may still get stringing at the really spiky parts of the test print, given there’s no space for a wipe, and that volcano is going to hold way more molten filament than a V6 or similar

Hopefully someone with more experience can add their 2¢, it was pretty difficult to research info online when I had PETG stringing - everything just says “tune your retraction” 😤

Edit: I mixed up the SR with the v400! In that case, Another thing to check is your bowden tube pneumatic couplers - unload the filament and tug lightly on each to see if they’re fitting securely. If they’re loose, your extruder can end up moving the bowden tube itself back and forwards, which affects your retraction

On models without a charge port, some of the batteries aren’t even flat when the pods are burnt out 🤷‍♂️

Worst i’ve read is around 3.8v under load, which is roughly 60% full… that would be a very destructive result compressed in the back of a garbage truck.

Been harvesting these so far but don’t have enough projects to use them in.

I only use Aliexpress via my browser. Was tempted to give Temu a try too but that’s a hard pass from me now

Not FOSS as it’s under another license, but there’s “FUTO Voice Input” if you’re looking for a local alternative to Google’s voice dictation on Android

gitlab.futo.org/alex/voiceinput

The repo has a list of supported and unsupported Android keyboards. Under the hood it uses OpenAI Whisper

Originally I watched the ad and couldn’t see what was wrong with it (from the perspective of a relatively isolated software developer).

However the top comment on the Verge summed it up in a way I understood, making comparisons to the crushing of various creative devices in the ad (instruments, cameras, paints etc) and the current creative landscape in reality (game studios, music production etc).

With that in mind, the timing is pretty poor IMO and feels quite insensitive to creative individuals

I love any kind of ebike to be honest. I’ve tried heavy front hub rideshare bikes, and a considerably nicer mid-drive specialized como 2022. They get me from A to B really comfortably and with ease, which is all I really need.

That said, I sadly don’t own an ebike myself, my personal bicycle is a dutch-style upright with a 7sp internal hub, and fully enclosed drivetrain.

The infrequent maintenance is a major convenience factor for me, so much so that I want my next bicycle to be belt driven, better so if I can find an electric one 👌

Are you planning to make your own OS for the watch? If so, there’s another smartwatch project called the “SQFMI Watchy” which is an esp32 combined with an e-ink display, RTC and some other sensors.

While I would highly suggest supporting the creators, there are clones on Aliexpress that may more readily ship out to your country

ElementaryOS sounds like a perfect fit for you, if you haven’t tried it already. Superb gesture support and consistent UI across all built in apps

That said, a lot of the gesture support has been implemented in Gnome and KDE now anyway, particularly partial gestures which previously had very poor support IIRC

If the Humane could recognise speech on-device, and didn’t require its own data plan, I’d be reasonably interested, since I don’t really like using my phone for structuring my day.

I’d like a wearable that I can brain dump to, quickly check things without needing to unlock my phone, and keep on top of schedule. Sadly for me it looks like I’ll need to go the DIY route with an esp32 board and an e-ink display, and drop any kind of stt + tts plans

16 years old? That thermostat has sure had a run, must have been designed pretty well to last this long without some electronic failure.

Assuming it’s cloud connected, anyone aware whether it got updates for the newer versions of TLS and root certificates? As an example I’m aware quite a lot of android and similar devices from that era have expired certificates now, and outdated/vulnerable SSL libraries…

Edit: Edit example

Aside from the other income channels mentioned by others, licenses for Grayjay and FUTO Voice Input.

Louis Rossmann is an employee there so I would expect that organization to have very strong staying power, especially considering the founder of that organization funded Rossmann’s R2R lobbying very early on (I no longer believe that is the case though: a dedicated charity was set up for that IIRC, which has recieved very generous donations)

Yes, this please. Although I don’t have a cargo bike, I load up all 3 sides of my pannier and fill a backpack with my cargo 😅

Never knew Wendover and HAI were run by the same person, wow 😳
