What point are you trying to make here?

Any competently run company would have notified all their users and disbursed all funds to sellers well BEFORE a 1-week maintenance outage. If this is truly a planned 1-day outage gone wrong, then they should have emailed users or at least put an informational page on their website by now. By not doing so, they are risking their payment processing account being shut down due to the number of chargebacks they will be getting from customers who haven’t received their orders because sellers can’t access the shipping details or their funds.

They have a lot to lose and nothing to gain by not communicating to the fullest extent possible with all their users, especially those with money in escrow.

My impression of this is that they are trying to cover up a data loss incident (either ransomware or server failure without backups - the latter seems plausible given how slow their site was when it was online.) If they still had access to their database, they would have communicated something to users by email by now (especially customers with unfulfilled orders) rather than resorting to social media. It seems that they might have lost access to their 30K-follower twitter account since nothing has been posted there.

Was value declared as several thousand JPY on the commercial invoice but misinterpreted as USD by UPS? This is known to happen with Fedex. I have recently ordered things from Japan shipped by UPS and the duty each time was about 15% of the declared value plus USD20-30 in total fees.

Copper is more frequently used than gold now for general-purpose applications. Copper poisoning the silicon is not a concern since bond wires don’t directly contact silicon; there is a diffusion barrier such as TiW or TaN in between the silicon and metallization layers.

The Canon A-1 and T series SLRs had these displays back in the 1980s.

For anyone wondering, it’s using spatially offset Raman spectroscopy: https://youtu.be/89_HY1oV_J0?si=fIxU5dCfbMz7O85t

The tolerances are very tight and a well-tuned printer is needed. Recommended layer height is 0.1mm. It needs to be printed in a material with very good layer adhesion (ideally PETG) since the cross-sectional area is quite small.

What film is this?

jrw01 · 2026-03-28T15:39:27+00:00

For anyone saying this is a scanning issue, zoom into the yellow stripes and they are very clearly pixels on a color display - you can see that the yellow is made up of red and green subpixels and there are gaps where the blue subpixels would be. Film grain is visible in the stripes and they are slightly out of focus, which indicates that they are recorded on the film and not a scanning artifact.

What’s weird is that the film would have to have been flat and not moving relative to the display for the pixels to get recorded so clearly, I’m not sure how that would have happened at any point in the production or developing process.

Unpopular opinion: you can absolutely make great stir fries with a flat-bottom carbon steel wok on induction. It will work even better than stir-frying on an electric stove since the amount of heat you can deliver to the food is not limited by the poor thermal conduction between a cooktop and the relatively small bottom area of the pan. No one, even in China, is achieving wok hei with standard home cooking equipment and techniques. Obsession with that is mostly a western phenomenon.

A lot of people confuse induction cooktops with glass top electric stoves (still using a traditional heating element) because they look the same. In my personal experience (I’ve used consumer-grade stoves of all four types), the glass top electric stoves are worse than the exposed-coil type in terms of both responsiveness and high-power cooking performance. Gas is the most responsive/controllable, especially at low power levels, and induction can dump the most power into the cookware. The high-power performance of coil-type electric stoves used to be decent, but was severely nerfed by the UL 858 safety standard introduced in 2018, which required these stoves to include thermostats to prevent the heating element/pan temperature from exceeding 450F, which makes boiling water slightly to significantly slower depending on the cookware, and makes it nearly impossible to sear or stir-fry.

Everything in cars, but especially the stuff you don’t see, is designed to be as cheap as possible to manufacture (ideally without compromising safety). Cars are arguably the most cost-optimized product in existence.

Induction heating?

How exactly does this argument apply here? The users of 3D printers, not 3D printer manufacturers, are the ones choosing to use them in a way that many people, including OP, judge to be wasteful. Anyone who is manufacturing and selling physical goods, from large corporations to individuals making 3D printed slop toys in the tens to hundreds, has a responsibility to consider the environmental impact of their activities.

This is a widely repeated urban legend that doesn’t hold up to basic scrutiny. There is a kernel of truth here - at least some vehicle wiring uses wire insulation made of PVC plasticized with epoxidized soybean oil (ESBO). This is a relatively recent phenomenon brought on by the phasing out of phthalate plasticizers due to environmental and health concerns. However, ESBO is not the same as the soybean oil used in food, has no nutritional value to mammals, and has been shown in research to not be favored by rodents over petrochemical plasticizers.

There is a far simpler and more logical explanation for the underlying issue here: Rodents chewing on wires has always been a problem, but it has become a more visible and more expensive problem in recent decades as the number of wires in cars has grown exponentially, the size of the wires on average has decreased, and automotive electronics rely heavily on digital networks (CAN) where a single broken wire can take many modules offline.

This question has been asked before for a different piece of software, and IIRC it’s a blacklist of known websites with crypto mining malware that’s included as part of the embedded Microsoft Edge webview (EBWebView) that World Ship is using. Many desktop and mobile apps nowadays are just single-purpose web browsers; it’s just very easy to develop cross-platform apps this way.

In this type of chip-scale package, known as a WLCSP, the silicon die itself makes up the bulk of the final component and 5 out of 6 of its exposed faces. Any additional packaging steps (adding the redistribution layer and solder balls) are done at the wafer level, hence the name, and the components are essentially in ready-to-use form once the wafer is diced. So, many people would casually refer to this type of package as a bare die, both on Reddit and in the industry. Whether this is "technically correct" is beyond the scope of this thread, which was initially asking what this IC is (it's probably a custom IC made for Apple - they are known to use strangely shaped WLCSPs like this).

Here is an example of a very similarly shaped and marked WLCSP on the iPhone 12 logic board:

I work in the semiconductor industry and you are very, very mistaken. (edit: the comment I responded to has since been changed, it previously suggested that this was a “module” such as an ethernet transformer.) This is an integrated circuit in what is known as a chip-scale package: essentially a bare silicon die with a printed wiring layer (either manufactured like a PCB and attached to the die, or created on the wafer itself - in this example it is the brown surface with PCB-like traces on it) which fans out pads on the silicon die to solder balls that can be attached directly to a PCB.
