ourcat··on Once the disease of gluttonous aristocrats, gout is now tormenting the masses
Have you tried Cranberry juice/extract? I've often heard that it can help the body break down the Uric acid.
ourcat··on Ask HN: Good C++ code bases to read?
Indeed. 'Blinky' is the 'Hello World' of microcontroller programming ;)
ourcat··on Ask HN: Good C++ code bases to read?
Not so long ago I decided I wanted to learn some C++ and ended up getting some cheap micro controllers and starting with Arduinos and learning from the examples in various libraries.

Now I'm having a lot of fun, still learning, while programming the ESP8266 and especially the ESP32 (via PlatformIO). Playing with Wifi and Bluetooth too.

The best thing in my view about learning things with micro controllers is the 'tangible' result. Seeing things happen or move. (or not! and why.)

I thoroughly recommend it, along with all the other responses here.

ourcat··on A Youtube video downloader written in Go
Well, their main issue is serving ads with the content.

They don't want applications having the final .mp4 url to embed without them.

ourcat··on A Youtube video downloader written in Go
'Actively-maintained' is another way of saying 'We play Whack-a-Mole with YouTube every time they change how the ultimate .mp4 video file url is obtained via the private API'.

ie: If you didn't update youtube-dl that often, you'd often find that it stopped working.

ourcat··on Vaccine hopes rise as Oxford jab prompts immune response among old and young
A certain amount of 'reactogenicity' is expected with most vaccines. ie: "expected" adverse reactions.
ourcat··on The physiological effects of slow breathing in the healthy human
I do this when I shiver in the cold. You'll stay warmer for longer.
ourcat··on Screego – multi user screen sharing via browser
Looks nice. Good documentation too.

One thing I'd add though, is an example for HTTPS (eg: with certbot) in your Reverse Proxy section.

ourcat··on Do things that don't require scale
All depends how much energy or resources you have at hand to deal with them.

In my experience, 'free' users can often be far more demanding (and draining) to deal with. While this is obviously some value to garnered from them, they can rapidly suck the life and passion out of a system or network, to the detriment of those who have paid, which can then create dissent from actual 'customers'.

ourcat··on 'Long Covid': Why are some people not recovering?
I know a couple of people who caught Covid-19 back before the summer, who both described the same symptoms after recovering (and testing negative). This was a while before all this talk of 'Long Covid' came about.

Since we're all different, and will all fight viruses in different ways and strengths (depending on health/existing cnditions etc.), there'll be so many variations in how much of a 'toll' fighting it has taken on our bodies (and minds).

Since this ia a 'novel' virus, we can only really base any conlusions on the empirical evidence as it comes in.

ourcat··on USB-C was supposed to simplify our lives, but instead it’s a total mess
I'd say the spec is fine. It's the implementations of it that's a mess.

Mostly when it comes to the different voltages they can be set to provide.

Here's a video I saw recently which explains all about USB-C 'PD' (Power Delivery): https://www.youtube.com/watch?v=iumAnPiQSj8

ourcat··on Do things that don't require scale
This reminds me of something I used to say:

"I'd rather build something with 1000 paying customers instead of 1,000,000 free users"

(... who I'd eventually have to try and monetise in uncomfortable ways)

ourcat··on Tell HN: Never search for domains on Godaddy.com
Interesting. I'd never considered Google for my domains.

Any idea if the '£10/year' is every year? Or does it go up after the first year?

Also, I found it weird that they promote a .app and .dev TLD as 'More Secure'.

ourcat··on Is Facebook down?
It's back now. But everything did indeed grind to a halt for a few minutes.
ourcat··on How to stream audio from your phone to your laptop with PulseAudio
Very neat. I assume this would work work on a cheap Raspberry Pi3 or 4 too, via their Bluetooth and out via its audio jack.

Now I think of it, I seem to remember seeing a project like this to make use of old wooden-box speakers (with a small amp inside too.)

ourcat··on Relativty – An open-source VR headset
That's true. I actually have a few cheap card-like gadgets. And they're certainly not fresnel lenses. ;)
ourcat··on State of Self-Serve Website Building in 2020
Re: 'Headless CMS' in the article: Since the introduction of the JSON REST API, I've been using Wordpress as the back-end to various personal and professional projects, built on various web and native mobile frameworks.

One of the good things about Wordpress is the familiarity to it from the people who have to use it. (Authors/Editors/Contributors). (Though, I'd say Gutenburg might stir that up a bit).

Also, once you learn how to write plugins, the sky's the limit really.

ourcat··on Relativty – An open-source VR headset
There's an AliExpress link in the README of the Github repo.

Though, I'd imagine you could use ones from cheaper 'phone-to-face' Google Cardboard-style ones.

ourcat··on Relativty – An open-source VR headset
It's great. But make sure you have a decent 5GHz router.

I use a TP-Link AC1900 and Half-Life Alyx works great.

VirtualDesktop completely revolutionises the Quest. It's an absolute must-have.

I wouldn't be all surprised if it got bought by Facebook at some stage, or they build something that does exactly the same thing.

ourcat··on Relativty – An open-source VR headset
If it supports 5GHz Wifi, something like this could eventually work well with VirtualDesktop (An incredibly useful app which makes the Oculus Quest truly wireless and capable of playing all SteamVR games from your PC).

Keeping all the GPU overheads off the headset is the way to go. (And will also be seen eventually with future '5G' wireless systems (not to be confused with '5GHz' Wifi) which will put that 'grunt' in the cloud.)

ourcat··on Relativty – An open-source VR headset
I did a similar thing to design a 3d printed mask.

I used an iOS app called ScandyPro which gave me a mesh which I then imported into Fusion360 and modelled some lines/layers of the curves around my face. Then I performed a 'loft' between them.

The result was a perfect fit.

ourcat··on Chrome is not the new IE
Back in the day IE always had an 'advantage' purely by the name: 'Internet Explorer'.

When people 'got a computer' to 'get on the internet', seeing that icon on the desktop got them where the thought they needed to be.

Very, very few people, even years after after Chrome and Firefox came out, even knew they had a choice over the (browser) matter of getting 'on the web'. (There are some classic videos out there of voxpops of people being asked about 'the web' and 'the internet' etc.)

(To begin with, for me, it was Spry Mosaic then Netscape from about '93.)

ourcat··on [dead]
Agreed. That interface could be so much easier to navigate. Might be easier on a touch interface.

Even some simple ordering by recency of activity would be a vast improvement.

Or some 'momentum' to the scrolling of the tree.

ourcat··on Show HN: Olaf – Acoustic Fingerprinting on the ESP32 and in the Browser
I'm constantly impressed by the ESP32 and have dabbled in a few project ideas.

You could even use them to talk to other ESP32 devices (in other dresses!) using WiFi/UDP, Bluetooth LE or Espressif's own 'ESP-Now' mesh networking (which recently blew my mind).

I've done a few RGB LED Matrix based ESP32 projects now. This project has given me a few ideas.

Thanks!

ourcat··on Jacques Cousteau’s grandson wants to build the ISS of the sea
Curious lack of any mention of Jacques Cousteau's first son (and father of Fabien) Jean-Michel, who I met about a decade ago while doing some work for his Ocean Futures Society.
ourcat··on Firefox 80
The Google Chrome app on a Mac can also still have previous versions inside it.

Right-click on it and go to Show Package Contents. Then navigate to Contents > Frameworks > Google Chrome Framework.framework > Versions

You'll also see a symbolic link to 'Current'. Right-click > Get Info. on that to see which folder to 'not' delete.

ourcat··on How I helped fix Canadaʼs Covid Alert app
Naturally. I'm just saying that I would have thought it had something to do with that first, before the captive portal clue.

I assume React Native doesn't require CORS, like the web version does?

ourcat··on The robotics revolution is here, and it's changing how we live
If relationships with China go further south, I've been wondering/worrying if that might eventually (and sadly) affect the supply of cheap components to young, developing 'makers', many of whom ultimatately tend to end up in this line of industry after years of tinkering.

The knock-on effect could be huge in the future.

ourcat··on How I helped fix Canadaʼs Covid Alert app
Re: the 'disturbing' Google chatter/endpoint, a 204 HTTP status reponse is also the expected code for a pre-flight OPTIONS request to support CORS.
