See marketing in action, a few days later it reads “up to 99% biofilm is removed from your teeth, more than any conventional toothbrush on the market”

The keychain might be a candidate.

I wonder if it also just replied with a U+1F4A9 PILE OF POO.

Not sure how it is for others, but for me tapbot Tweetbot is working again since today; is the API back up?

[cmcfadden → mkoc]

Paul mentioned that they had a way to push new API info to the clients, so I think they basically just re-registered the app as a YOLO thing to see how long until Twitter pulls the plug again.

[clouddrover → mkoc]

Tweetbot partially works because they're using new API keys:

It's a temporary workaround at best. The new API access is rate limited and Tweetbot will likely be banned again.

[karlshea → clouddrover]

The new keys are already not working for me.

[clouddrover → karlshea]

It certainly proves that the whole situation is intentional. Here's what Paul Haddad (Tweetbot developer) says about the new keys failing:

I was able to get an access token, and my timeline loads in Tweetbot, but I can't see mentions or activity, and I can't tweet from it.

On: 300 Drones Formed a QR Code That Rick Rolled Dallas on April Fools' Day

Decodes to http://www.d52.io/

[scotty79 → mkoc]

Does it even work? QR code made of lights?

Or do you need to manually invert a photo before decoding?

[aembleton → scotty79]

It works for me, using Firefox to scan the QR code in the video.

Do you have a smart phone? You could try it yourself.

On: Raspberry Pi Zero 2 W die shots

[mkoc]

have a look here [0], Fig 1; the spacer serves really as a mechanical spacer (if dies are same or similar size); also nice for heat spreading.

The sensor is from ST. Besides many previous publications/reveng/leaks, this is also in the systemplus slides on page 16, top right.

This, though? https://www.reuters.com/article/apple-forecast-ams-idUSL8N1Z...

AMS provides Apple with optical sensors for 3D facial recognition features on its newest smartphones

“We see a risk that Apple moves to dual sourcing for the face ID – which currently is single sourced from AMS - in order not to rely on deliveries from just one supplier and also in order to have a favorable pricing power,” said Hauck & Aufhaeuser analysts in a note to clients.

On: An iOS app update that annoys me

[mkoc]

Anyone knows good alternatives with a similar feature set?

[vestrigi → mkoc]

Coins by Yuzhou Zhu – seems very similar, has a few more features but not in an obtrusive manner

Superb article, huge amounts of detail. I particularly liked Figure 38, which seems to be a lens cap labelled "Remove Before Flight" :-)

The article is also a good test of acronym learning.

On: Windows Timer Resolution: The Great Rule Change (2020)

[mkoc]

Would anyone have an idea how to find out which program set the timer resolution? Would be very helpful in investigating battery drain problems. Any ugly hack is welcome.

[abbeyj → mkoc]

I believe that this is included in the report generated by `powercfg /energy`.

[brucedawson → abbeyj]

powercfg will indeed report on what programs have raised the timer interrupt frequency. However powercfg (and clockres) both just report on the state at a moment in time. Many programs repeatedly raise and then restore the timer interrupt frequency and powercfg utterly fails to understand this. And yet, powercfg is the best that Microsoft has supplied.

I eventually decided to write a better alternative. The batch file below (requires Python and Windows Performance Toolkit to be installed) will report on all timer interrupt changes by all processes over the time period recorded:
