Is a DDR trainer really that hard to write?

Since this is an unencrypted binary, I'm sure it won't be difficult to reverse engineer. And it will definitely be open source sooner or later. But first, we'll try to convince Rockchip to open source it. Especially since the RK3576 has other proprietary parts, such as OP-TEE and some registers. Also it has a Cortex M0 core, which is also not documented.

Our wifi chipset MT7921AUN has an open driver in the mainline. Of course wifi firmware is binary. But you can use the whole system without a wifi. Main idea is to make the platform open, so you don't need blobs to boot and use the system.

We're currently negotiating with Rockchip and will first try to convince them to open source. This particular binary isn't a problem right now. I'm sure it will be open source sooner or later. All efforts are currently focused on hardware validation, and software is being developed only in areas where hardware verification is required.

For those who work from home, we have made it possible to hang the device on the door so that no one knocks on your door when you are on call. Also, by integration with the BUSY App it can automatically block notifications on phone and desktop when you are in focus mode.

Since then we have changed the name and added many features.

Hi, Pavel Zhovner here, Flipper Devices CEO. Yes it's our product, but it's not ready for announcement yet, so we keep it secret.

Right now, we are working on implementing Matter smart home protocol and will slightly change the product concept.

Never see so much money, haha. But this just a beginning. Next challenge is to produce it and deliver. Also I'm afraid of NFC goal, because this is a HUGE part of new code. But I will do my best to get this project done.

Unfortunately many other vendors encrypts firmware updates, like Panasonic do. I dream to hack Panasonic GH5 and G80 cameras firmware to tune some options.

There is a tool to binary patching Pansonic GH4 and GH2 firmware called Ptool. https://www.personal-view.com/faqs/ptool/ptool-faq It decrypts encrypted firmware, patch binary and then encrypt again. So you can update firmware via default process.

Whatsapp is so ugly and stupid messenger:

1. Desktop client is a proxy for mobile app. If phone goes offline, desktop client is disconnect.

2. You can't add contact from desktop client. So if you use whatsapp for business, you need a phone right right next to desktop PC and every time switching between phone and desktop.

3. Only local contact list and only one device. If we have few managers that uses WhatsApp for sales or tech support, we can't share one account for few PC's.

4. Impossible to logout from mobile app. To logout on iOS you need to delete WhatsApp and then install it again.

5. No chat logs on the server. You need to backup your chat's INTO THE FILE and then move it to another device.

6. Only one device! You can't simultaneously use whatsapp on phone and tablet.

I can continue this list very long. So I do not understand why this crap is so popular?
