nicolaslem··on Firefox maker Mozilla prepares Gmail-like Thundermail
Fastmail does the catch-all thing.
nicolaslem··on An e-bike that charges off USB-C
> I'd also love to see any sort of device dare to offer parallel charging; plug in two USB-C cables to charge twice as fast. Sounds silly, can be a little tricky, but I just want to see someone do it because why not.

This already exists, I have a power bank (Anker C300X DC) that does this. It has two 140W USB-C inputs that can be used simultaneously for charging at 280W.

nicolaslem··on I won't connect my dishwasher to your cloud
I am willing to bet that these features you started relying on will stop working within five years.
nicolaslem··on The smallest ESP32 drone you can fly with your phone Powered by XIAO ESP32S3 [video]
Yes, the project does not make a ton of sense but it was for me the opportunity to learn ESP32 and have some fun. The outdoor module is constantly in deep sleep and only wakes up for a few seconds when the button is pressed. I put a 1000 mAh cell as that was the biggest capacity that fit the enclosure, that's probably way too much as in deep sleep the ESP32 barely consumes anything.

The indoor module is plugged straight into a wall socket so no batteries. When someone is at the door I am notified by Michael Scott: https://www.youtube.com/watch?v=umDr0mPuyQc (maybe I will get tired of this, for now it's still fun)

For me the really cool thing with these XIAO modules is that they support charging a lithium cell via the USB port directly without any additional circuitry. I have turned one of them into to a wireless doorbell that get recharged via USB-C.
nicolaslem··on Flea-Scope: $18 Source Available USB Oscilloscope, Logic Analyzer and More [pdf]
I have a cheap handheld oscilloscope (ZOYI ZT703S, ~$80) that I find very convenient to have around. It's the size of a multimeter, runs on a battery and works well enough that I don't feel too limited by it.
nicolaslem··on Ask HN: Is onboard audio still good enough compared to dedicated Sound Cards?
It is mind-boggling how good the Apple dongle is, that something that tiny contains a good DAC and a headphones amplifier. I switch back and forth multiple times a day between the Apple dongle and a Universal Audio interface that cost many times more and I have never heard a difference.

However I hear a big difference with my laptop onboard audio and off brand dongles, they have an audible noise floor.

To the OP I would recommend getting the Apple USB-C dongle before spending big bucks on something else because for listening it's likely to be good enough.

nicolaslem··on Ask HN: Is onboard audio still good enough compared to dedicated Sound Cards?
The vast majority of audio interfaces on the market today are class compliant. They will work out of the box with any OS and even phones.
nicolaslem··on Choosing an op-amp for your project
The book "Small Signal Audio Design" by Douglas Self has an entire 50 pages chapter on selecting opamps for audio. The chapter roughly ends with this quote:

> One thing is obvious — the 5532 is still one of the great opamp bargains of all time.

nicolaslem··on I sent an Ethernet packet
> WiFi is internal to the ESP32 and works "out of the box", but wired Ethernet takes a bit of configuration for the WT32-ETH01.

I recently discovered the ESP32 and my only complaint so far is that Ethernet (and with it PoE) is not a first class citizen of the platform.

nicolaslem··on Show HN: I built an app to use a QR code as my doorbell
Any recommendations for a $25 wireless doorbell that actually works? I went through two of them and both stopped working after a year. The location they need to be installed in is slightly exposed to the elements and it seems cheap doorbells really don't like that.
nicolaslem··on Ask HN: Can a 5 year old i7 laptop compete with one made today?
In my experience audio is an order of magnitude more important than video.
nicolaslem··on 12 months left to keep Copilot off your desktop or learn Linux
> HDR still doesn't work properly

The Steam Deck OLED has an HDR screen and as far as I can tell it just works.

nicolaslem··on Why are my ZFS disks so noisy?
I totally understand the article title, I have a ZFS NAS that makes the same kind of noise as described there. Roughly every five seconds the drives make sound that is different from the background hum of a running computer. In a calm environment this is very distracting. I even had a guest sleeping in an adjacent room complain about it once.
nicolaslem··on Nintendo Kawaii Progress (Keychain-Sized Nintendo Wii)
> An Xbox One in a Steam Deck form factor with decent battery life is probably doable.

In my mind the Steam Deck is already a portable Xbox One/PS4. Most of the hit titles of that generation were eventually released on PC (with a few exceptions) and the Steam Deck plays them flawlessly.

nicolaslem··on Entire staff of game publisher Annapurna Interactive has reportedly resigned
It seems you just wanted a different game than what Stray is.
nicolaslem··on Writing a tile server in Python
I believe the WSGI spec is a bit unclear on this but some WSGI servers can give back control to the app when the connection gets closed. I use Flask and Waitress for long-lived server side events and my app is notified when the client closes the connection before the end of the stream of events.
nicolaslem··on Google and Microsoft now each consume more power than some fairly big countries
Since electricity is fungible at the continent scale, it only makes sense to look at the energy mix of society at large. Google could pay a premium to buy only renewable energy from the grid and have an impressive 100% green energy mix, simply displacing emission to the rest of us.
nicolaslem··on Let insects eat your plants
You mean windows? Estimates show they kill roughly the same number of birds as cats.
nicolaslem··on Home Assistant has a new foundation and a goal to become a consumer brand
Right but the point I am making is that Apple put a hub in tens of million homes without having to convince anyone to get a hub.
nicolaslem··on Home Assistant has a new foundation and a goal to become a consumer brand
I have been running HA for four years. I wish them luck but it's hard for me to imagine they will succeed at going beyond the tinkerer demographics and becoming a consumer brand. A few reasons:

- It has improved a lot over the years but it is still not polished enough for end users who want the thing to just work. Every integration works in a different way. The recommended way of managing z-wave devices changed three times since I started using it.

- Similar hubs already exist commercially and all of them failed to reach a wide audience. The Apple approach of bundling the hub with the Apple TV is a great move in my opinion, consumers are excited to get the latest shinning Apple product, none of them would care about a home hub.

nicolaslem··on Android features I envy as an iPhone user
Not on your hardware, not your data. I understand most people may not care about it but tech companies have shown over and over again that they do not mind cutting access to the data they host, even to paying customers.
nicolaslem··on TrueNAS Core versus TrueNAS Scale
This reads like the ramblings of someone salty about the move to linux, nothing very interesting in my opinion.
nicolaslem··on Self-hosting on a Raspberry Pi cluster
From my experience, being comfortable with networks and systems outside the cloud is a valuable skill that not a ton of people possess. It may be surprising to some of you, but there is an entire generation of syadmin/devops that have never touched a switch or a bare metal server.
nicolaslem··on How to Determine the Error of an Air Quality Sensor?
I have a Fibaro CO sensor on my z-wave network which is relatively low-pain and lock-in free. In my opinion CO monitors are a bit different from say CO2 or VOC in that they should really show 0 ppm at all times. If they don't you want them to alert you first and optionally record the data/send it somewhere. That's why I am fine with this device being treated more like a smoke detector than an IoT device.
nicolaslem··on Reflections of a bird collision monitor
If you routinely have birds crashing in your windows, I encourage you to put dot stickers on them. I did that after having three birds crash in the span of 10 seconds while I was staying right behind it. Not a pleasant memory but at least it doesn't happen anymore.
nicolaslem··on How much faster are the Gnome 46 terminals?
My distro recently upgraded to Gnome 46 and as someone who spends a big chunk of their day in a terminal, the difference was very noticeable. Great work to everyone involved!
nicolaslem··on Why you should use a terminal editor to write a commit message
> The editor would give me too much freedom and I am likely to ramble!

Please do! Context not included in the commit message or the code is lost forever.

nicolaslem··on 6.2 GHz Intel Core I9-14900KS Review
For single core, it wouldn't perform as well as you think because performance per watt is not linear. It would push this hypothetical CPU well into the zone of diminishing returns.

For multi core you can just look at AMD Epyc CPUs which achieve great performance by using many (up to 128) relatively low power cores. An all core load pulls around 400W of power.

nicolaslem··on 6.2 GHz Intel Core I9-14900KS Review
> Most enthusiast motherboards default to limits near 4096W of power and 512A of current.

No, that's just a way to set no upper limit. A very beefy desktop power supply is 1600W, and that's typically over-specced to handle brief surges of power.
