timc3··on The US will finally allow adaptive beam headlights on new cars
Adjust your mirrors to a better position. The EU solution helps adjust it to what drivers think they need.

Here is an example how: https://www.defensivedriving.com/safe-driver-resources/how-t...

timc3··on I wish my web server were in the corner of my room
Network router with DNS resolver, internal domain, all DHCP clients get registered with a name as a subdomain. mycomputer.networkname.lan - I use pfsense, but lots of others support this.

You could have your own top level domain as well.

timc3··on The 4th Year of SerenityOS
Congratulations to SerenityOS! Quite amazing seeing the progress over this relatively short time.
timc3··on Citrix acquired and merged with Tibco for $16.5B
Doesn't exactly qualify you for knowing about IT software.
timc3··on Citrix acquired and merged with Tibco for $16.5B
Because it is a very well known software company. I have never used Citrix, but to me its as a name the same way as VMWare, SAP, EMC, Salesforce and Intuit is.

Such a stupid stereotype. Maybe it is true where you live, but no where I am at all.
timc3··on Show HN: HiFiScan, a Python app to optimize your loudspeakers
Exactly. If you really want to get into it the depth of the construction of the panels you need is based on some maths - density of the insulation material and it's particular properties but all of that can be found out on forums such as this one: https://gearspace.com/board/studio-building-acoustics/ - vs the frequencies you wish to treat.

You can put your room dimensions into a calculator and get a rough idea of some of the try and find the modes of the room - which you want to treat, though sometimes it takes trial and error as well. But you want to treat the point of first reflection and then have bass trapping in the corners.

Don't buy that "acoustic foam" that looks like egg cartons, it's rubbish.

Fabric that you can breath through easily for looks. Under than you can be very thin fabric that makes sure that the fibres from the insulation doesn't escape.

I use this for looks: https://www.camirafabrics.com/en/contract/inspiration/acoust...

Headphones are excellent, but I find I have a different experience with headphones compared to music coming out of speakers. Sometimes I prefer one over the other.

Seems to be some kind of DRC.

$10K digital audio cables are never a good idea.

I remember I went to some audiophiles house once to demo some speakers, and his "hobby" seemed to have taken over the house and common sense. He had crazy expensive audio equipment and some of the thickest cables I have seen, with the cables all suspended on little bridges.

All this in a room which was basically a square brick construction with glass windows on 3 sides, no thought to any treatment. He didn't seem to understand that the room was effecting the sound more than any DAC, Amp, Cable, or any of the other voodoo that was going on. I couldn't properly demo the speakers because of a particular standing wave. I concluded he probably had a hearing problem, he concluded he needed to upgrade a cable.

It's cheap compared to a Trinnov system. But honestly you might be better off spending 300eur/usd on wood, Rockwool and some fabric.
timc3··on Show HN: HiFiScan, a Python app to optimize your loudspeakers
Yeah, those are kinda cool. They have the added advantage that they don't have a huge amount of bass, though what they do have is impressive for their size to be fair.

But because of their size they don't always activate room acoustics in a crazy way, and a lot of people monitor with them fairly close so don't need them loud either further lessening the problems.

timc3··on Show HN: HiFiScan, a Python app to optimize your loudspeakers
Nope, it's better to treat the room first, then invest in some quality monitors like Neumanns. Basic budget monitors will do great in treated room.

This type of software, is just a bandaid and really doesn't work very well (though it can work better with headphones). Properly thought out and tuned acoustic work is what is needed.

I am lucky enough to have a spare room in my house, and set out to build a studio (an almost life-long dream) and decided that I didn't want to compromise on the acoustics and spent some time looking into the subject. In the end I built it myself with a huge amount of acoustic treatment (lost a large amount of the volume room), but more that that I enlisted the help of a professional who could do the maths and help with not just the trapping but also the panels that are needed. In the end after I built it was also tuned with DSP by the professional, has what you would normally call 4-way speakers with the subwoofers going to a higher frequency than most would consider normal and even the desk was specifically chosen to not cause a problem for the listening environment. The difference between this and something like Sonarworks (commercial software that I tried for a laugh beforehand) cannot be overstated. It's basically flat between 23hz (slightly rises at 20hz I believe) and 20Khz - we actually tuned in a more natural response curve.

It's still a home studio because it's in my home and I don't do anything commercial with it, but it's pretty much mastering grade, all with materials that are available in a builders yard and the special sauce, someone that knew what they are doing. Not everyone has the room or space to do this, but most people can build some bass traps and something to tame first point reflections.

Well according to my Grandmother she did actually work, as my Grandmother was around her at the time.
timc3··on Toyota patents plans for EV with manual transmission and clutch
I can feel it on my Taycan (it’s one of the most powerful models) but it’s not bad at all.

Porsche has a lot of experience with gearboxes which probably explains why they can build a reliable one when dealing with the power and torque.

timc3··on PC wakes from sleep when changing clothes
You do realise that you can get server parts for a custom build? That is what I run for home use, it’s the most reliable machine I have personally owned.

And that even those workstations you think are reliable can and do have problems (I have first hand experience of that), like all computers. It’s the response time and contracts that I wanted to problems that I used to look for when buying workstations and that doesn’t always help when it comes to firmware issues.

There are plenty of data centres and companies that are running what you call custom builds. Look at Hetzner, backblaze, or even bigger companies that role their own.

$100k is a drop in the ocean for experience, that is like a typical week purchasing for some, and wouldn’t even cover the cost of some machines I have used.

timc3··on Ask HN: Whatever happened to dedicated sound cards?
I have MOTU, Universal Audio and Audient which are all good. But they are general aimed at musicians/producers etc. I would also recommend RME if you use a Mac or just the ASIO drivers on Windows.

The drivers are really important, and often audio interfaces aimed at professionals will use a driver that a DAW can utilise with control over latency. macOS users tend not to need to worry about this so much because as long as they are good it works, and on DAWS on Windows I use ASIO because MME, WASPI and WDM have had poor behaviour and/or latency in the past. But for general music listening those other driver types should be ok if the manufacturer supports them well - but this is where the problem might be.

I am guessing it might be the driver that sucks in your experience?

Have you tried S/PDIF output to an external convertor?

timc3··on Ask HN: Whatever happened to dedicated sound cards?
Probably going to sound pedantic, but a breakout box is different from an external audio interface or convertor. Breakout box typically only converts from one socket to another socket, like this one: https://www.tascam.eu/en/bo-16dxout

External audio interface (sometimes wrongly called a sound card): https://www.rme-audio.de/fireface-ufx.html

Convertor: https://www.rme-audio.de/m-32-m-16-ad.html

Actually a sound card: https://www.rme-audio.de/hdspe-aio-pro.html which can utilise a breakout cable or external convertor

timc3··on Ask HN: Whatever happened to dedicated sound cards?
I moved over to Thunderbolt plus Audio over Ethernet. This is where the growth is (Dante etc) in the high end. I think I have 60 channels of IO and thinking of adding another 40.

USB is good enough for a lot of people, though I am not a fan so that covers the average prosumer.

MIDI is a totally different subject, but I can run MIDI clock from audio which is as tight as it gets these days. See USAMO from Expert Sleepers.

timc3··on Why are D-sharp and E-flat considered to be two different notes?
Early electronic instruments, particularly before the 1980s had tuning all over the place, and you would have to wait 30 minutes to get anything resembling stability, even then nothing was guaranteed.

Think it would be possible to mockup some really interesting tunings/temperaments in BitWigs grid or Max4Live.

timc3··on Citroen 2cv pages
Think we have to agree to disagree. It's extremely interesting, non-conformist but I wouldn't call it beautiful - I have actually seen inside it in real life.
timc3··on 40 years ago, Tron changed sci-fi movies
I wouldn’t say under appreciated, her albums sold millions and she has received several awards and is an important figure in the history of electronic music.

Just not as well known as she should be in recent times.

timc3··on Robertson vs. Torx screw drives (2021)
Not my experience, I buy Torx screws by the hundreds and haven't stripped a single one.

I do use an impact driver sparingly or the torque setting on drill/driver - plus Bosch or Makita bits.

timc3··on BMW F Series Gear Selector, Part Two: Breakthrough
The BMW ZF is much faster. They are even using it in their M cars.
timc3··on BMW F Series Gear Selector, Part One: Failures
I like that it has two gears (I own one).
timc3··on BMW F Series Gear Selector, Part One: Failures
Same here as well. This age of BMW was known for having a great UX, from the computer system to the drive controls.
timc3··on BMW F Series Gear Selector, Part One: Failures
And they are tuned differently in different vehicles and different manufacturers. BMW does it the best IMHO out of those using that ZF transmission.
timc3··on BMW F Series Gear Selector, Part One: Failures
On my F31 (which I no longer have) I thought doing that just put the gearbox in sport mode, but to change the engine response you still need the buttons. Need to try it in my G series sometime.
timc3··on Why Jony Ive left Apple to the ‘accountants’
That makes him a pretty poor designer, particularly in the industrial sense.

If you can’t balance those constraints you are not a good designer.
