Thank you, I see this viewpoint better now. Not certain I'd make the headline different knowing this, but this is good to keep in mind.

When you read "Linux malware", do you interpret it as "malware baked into Linux"?

Script to paste clipboard contents into a VM without guest utils and data leaks(github.com)

I hate having to install VM-specific guest utils all the time when I just want to paste some text into the VM. Here's a script that emulates keyboard input and just works. ASCII-only, sadly. Also, in VirtualBox, when you turn host-gues

That's why I won't be doing it myself - I'm just going to provide the platform, there are already people working on an open-source baseband, and they're much smarter than me =)

There's a GSM hardware switch - https://hackaday.io/project/19035/log/60071 - so this is the way to go then, simple as that =) So far, the software is going to assume that the modem is on at all times -

Each time ZeroPhone comes up on HackerNews, I learn something new that helps me go on =) Thank you, will be researching it when I'll be working "alternatives to Pi" topic =)

Oh, I do agree. The problem is - who's going to write it? I'm an one-man army so far, this is going to change once people get their hardware from the first batch I'm finishing now, but for now the project still needs contribu

Answering to your "GSM not open" comment - yes, the GSM baseband itself is not open-source, and I won't be able to change that alone - I have neither skills nor time. My plan is to make all the other parts of the phone open-s

The video is not yet ready (I'm still filming it) - but I'll make sure to post it here =)

The baseband OS is separate from the Linux running on the Raspberry Pi, the modem can be put in hardware RESET state - so, there's unlikely to be a way to execute malicious code on the Linux side by using a modem exploit, if that'

Hey, other programmers manage to write software that isn't riddled with bugs, I hope to be able to keep up with them =)

The display is an OLED, and its power draw is kinda negligible - so the worst offenders are still CPU, WiFi and GSM. I'm going to add an E-Ink display someday - mostly for experimentation, as hardware upgrades like this will require so

You're mostly right on your assessment - I don't intend it to be a good burner phone. There's the possibility to swap in GSM modems (thus changing IMEI) - except that the "manufacturer" part in IMEI is going to stay

My estimates show about 5 hours for the assembly time, so unless you get paid $1000/hour, this is not going to cost that much =) As for the time invested in software and hardware development - yep, it takes time, like any project is go

You can use a spare Bluetooth keyboard (or even a USB one), and I hope to produce a QWERTY keyboard attachment for ZeroPhone this year. In general, this is going to be one of the most important addons I'll be working on this year - bot

I don't think that any commercially available GSM modems actually have open-source GSM implementations - SIM5320 isn't an exception, sadly =( So, compared to AOSP, the main difference is that this project is open hardware (excludi

The GSM module manufacturer has taken care of IMEI, same with certification, AFAIK =)

I generally post all things ZeroPhone on Hackaday.io - https://hackaday.io/project/19035 - the blog is just for short random notes that might be useful to someone.

Yep, that's one of the side effects - you can plug some 2.4G transceivers (like NRF24L01, using an adapter) in the expansion port to talk to 2.4GHz stuff, or use some TI sub-GHz chips for 433/900/868. Also, I'm wondering

I'm working on a 3G modem board this week, based on SIM5320 (as suggested in a HackerNews comment, IIRC) - the way I'm designing it, it's pin-compatible with 2G modem I have now, so should be a drop-in replacement. Hope to ha

The battery life is still unoptimized - I haven't even played with CPU clock scaling, WiFi is always on and its power management is at default settings, and there are a couple more things I can do that'll improve battery life (lik
