First impressions: Yes, Apple Vision Pro works and yes, it’s good. | TechCrunch

But, I’ve used essentially every major VR headset and AR device since 2013’s Oculus DK1 right up through the latest generations of Quest and Vive headsets. I’ve tried all of the experiences and stabs at making fetch happen when it comes to XR. I’ve been awed and re-awed as developers of the hardware and software of those devices and their marquee apps have continued to chew away at the “conundrum of the killer app” — trying to find something that would get real purchase with the broader public.

Passkeys: Using FIDO for Secure and Easy Authentication

 — 

Passkeys, the popular name for FIDO, are not only easy, they offer better protection against phishing than other forms of multi-factor authentication. This is how they work.


Passkeys.io – A Passkey Authentication Demo

 — 

What is a passkey? A passkey is a new way to sign in that works completely without passwords. By using the security capabilities of your devices like Touch ID and Face ID, passkeys are way more secure and are easier to use than both passwords and all current 2-factor authentication methods.


Apple’s File Provider Forces Mac Cloud Storage Changes - TidBITS

 — 

Over the last year, cloud storage services Box, Dropbox, Google Drive, and Microsoft OneDrive—and probably others—have migrated from custom kernel extensions to Apple’s new-ish File Provider extension. It provides an Apple-approved framework for integrating remote files into macOS and displaying them in the Finder. I touched on this move a year ago in “Cloud Storage Forecast Unsettled, with Possible Storms” (4 February 2022).

Application Holotypes: A Guide to Architecture Decisions - JASON Format

 — 

Analyzing the characteristics of real-world applications is difficult. We often make generalizations about applications we see in the wild, both anecdotal and statistical: "Single-Page Applications are slower than multipage" or "apps with low TTI loaded fast". However, the extent to which these generalizations hold for the performance and architectural characteristics we care about varies. I believe one of the primary determinants of this variability are a product's features and design constraints, and classifying applications based on their features & constraints can enable more targeted and impactful solutions to the problems faced by each.

11 Intriguing Engineering Milestones to Look for in 2023

 — 

The initial segment of what will be the first underwater fiber-optic link to skirt the North Pole, connecting Japan and Europe, will light up in early 2023. This stretch, called Iris, will link Iceland to Ireland. In subsequent years, the Far North Fiber project will lay down a cable through the Northwest Passage, connecting Iceland to Greenland, then Canada, Alaska, and finally Japan. Far North Fiber will help increase the geographic diversity of the world’s fiber-optic network; currently, submarine cables are laid along a few well-trodden routes, leaving the network vulnerable to local hazards, like ship anchors, earthquakes, or fiber-eating sea monsters.

Michael Tsai - Blog - C xor C++ Programming

 — 

It is not uncommon to hear about C/C++ programming as a shorthand for “C and C++” programming. This implies that C and C++ are similar, but distinct, programming languages with the obvious interpretation being that C++ is a proper superset of C. However, this does not accurately describe the situation. The C++ programming language is inspired by the C programming language and supports much of the syntax and semantics of C, but is not a superset that is built on top of C. Despite sharing a historical relationship to one another, the languages have evolved independently and are specified in separate language standards. Due to this separation of the two specifications, incompatibilities have crept into the shared space of code that can be compiled by either a C compiler or a C++ compiler.


The really tiny RISC-V emulator: But, can it run Doom? #RISCV #Emulation @cnlohr « Adafruit Industries – Makers, hackers, artists, designers and engineers!

The Transistor at 75 - IEEE Spectrum

 — 

SEVENTY-FIVE YEARS is a long time. It’s so long that most of us don’t remember a time before the transistor, and long enough for many engineers to have devoted entire careers to its use and development. In honor of this most important of technological achievements, this issue’s package of articles explores the transistor’s historical journey and potential future.

IF GRAIN MUST be dragged to market on an oxcart, how far can it go before the oxen eat up all the cargo? This, in brief, is the problem faced by any transportation system in which the vehicle must carry its own fuel. The key value is the density of energy, expressed with respect to either mass or volume.

$1 POV Display - Hackster.io

 — 

Persistence-of-vision, or POV, displays work on the principle that if a light blinks in front of your eye, you perceive it for some amount of time after it’s gone. Blink lights in sequence when moving, and you can create what looks like a static image. “Programmer with a soldering iron” B45i found a deal on ATtiny13 microcontrollers for roughly $.30 each, and was able to create a POV display with one for less than a dollar.
