kimburgesson Can Dell’s 6K monitor beat their 8K monitor?

That's a good point to highlight: 20/20 is not perfect vision. It's simply a benchmark for "good enough" vision. IIRC there are physical limits around 0.4 arcmin. People with good eyesight sit somewhere between the two.

Take a look at the HDFury products. The X4 should do what you need with those lower resolutions.

kimburgesson Can Dell’s 6K monitor beat their 8K monitor?

Nothing to refute - I was simply continuing from your highlight of pixel densities.

While PPI has stayed mostly static (which is a good engineering choice), plenty of other display parameters have improved: better contrast, faster response times, deeper colour, larger continuous surfaces. The 2015 MacBook display was impressive. Modern panels are too!

There's no sudden switch. All perception is a little squishy and dependant on the individual. For most people though, once you're creating an image that's 220PPI and viewed from 400mm or so it's probably better to dedicate bandwidth to better temporal resolution, colour depth, or lessening the compression/compute/power/cost needed to balance those three.

kimburgesson Can Dell’s 6K monitor beat their 8K monitor?

Forget 4K, 6K, or 8K. Pixel density is the spec when considering any display. It doesn't matter if it's a wearable, phone, laptop, monitor, TV, or stadium wrapping LED surface, the only important factors for resolution are the distance to the viewer's eyes and the distance between the pixels.

For context, 20/20 vision is the ability to perceive 1 arcminute of angular resolution. Beyond that point there are diminishing returns.

It's physiological rather than philosophical. Auditory stimuli are sensed through your ear and tactile through the somatosensory system (in humans). There's some crossover in the frequencies both can detect.

There's also some potential crossover in how these may be perceived. For example, experiments which show you may in fact be able to 'hear' through your fingers; https://www.nature.com/articles/s41598-022-06855-8.

kimburgesson Australian Government Style Manual

It was first published in 1966, so seems probable. Thankfully prose and the core structure of language is slightly less volatile than the JS ecosystem.

Excellent, concise guidelines.

To add to the 'see also' list, the Australian Government Style Manual (https://www.stylemanual.gov.au) is another great reference.

kimburgesson Future ultra-precise timing links to geosynchronous satellites

Nanosecond level sync is fairly achievable with Precision Time Protocol [1]. This is common in most media systems where small amount of drift will cause phase issues with audio. Not my area, but I believe it's seeing a few using in the DC space too [2] where they may be strong requirements around event ordering for distributed systems.

The White Rabbit Project [3] also extends it to the picosecond realm for research control and instrumentation systems.

Not a scratch on this project though.

kimburgesson Sennheiser HD 555 to HD 595 Mod

I picked up a pair of the 700 X's a couple of weeks ago - no complaints so far. The replaceable cable removes the only weak point in an otherwise completely repairable product. That lets me amortise any difference across a decade or so.

Beyer also recently release the DT 700/900 Pro X are someone of a spiritual successor to the classics. Importantly they now feature a detachable cables, includes a USB-C one with internal DAC and mic.

Communicating with other humans.

You have around 150ms of one-way latency before perceptual quality starts to nose dive (see https://www.itu.int/rec/T-REC-G.114-200305-I). This includes the capture, processing, transmission, decoding, and reproduction of signals. Throw in some acoustic propagation delay at either end in room scale systems and milliseconds count.

There’ll also extremely common in most hardware used for any realtime media processing. With them being mutable it can be updated to support new compression methods, or switched in field to drop a device between acting as an encoder or decoder.

> I'd also emphasize how little most of the people involved in these systems care about the quality of the archive. If it's good enough to a) confirm there was signal on the channel and b) understand the voices involved, it's good enough to not worry about further.

This is uncomfortably accurate. I work with the capture side of these system and people in that space care deeply about the integrity of the signal, but have little concern for what it contains. Archival is the inverse: the information content of the signal is what's important, not the signal itself.

kimburgesson The LLama Effect: Leak Sparked a Series of Open Source Alternatives to ChatGPT

An SMS, email, or even physical mail only agent would be pretty interesting. With the socially accepted inherent limitations (text only, async, some level of misinterpretation expected) of those interfaces I'd wager it'd be possible to convincingly jump the uncanny valley today. Forcing to a comms path that's not just real-time chat affords a little more suspension of disbelief.

Particularly with growing token counts, you can have a pen pal, virtual colleague, or friend to bounce ideas off, return to previous thoughts, and chat to in cases where a real one may not exist or be available. A little ELIZA-esque, but adaptable to different needs.

My only concern is this would be be primed for misuse by people already experiencing isolation to further retreat miss opportunity to grow real social connections. Also, any semblance of privacy over those mediums would be a nightmare.

Audiovisual systems integration. It's a mix of systems engineering, software development, DSP, acoustics, interaction design and physical infrastructure. Think of the tech that makes or captures sound or light at a venue, in meeting room, stadium or other bits of built environment. It's a fairly eclectic mix of disciplines and a lot of fun.

Obviously highly dependant on what you do. After being heavily screen only for most of my professional life, having the ability to print off a table sized drawing of an engineering diagram, review it, mark it up, and work with others in that process is really nice. It’s definitely more efficient in pure IO terms to work solely in the digital realm, but the forced interaction barriers help provide a little more room for rough thought before returning there for fine tuning.
