fmntf··on A radical proposal to keep your personal data safe
I'm sorry, but you are unfortunately wrong. Some colleagues are involved in the development of a vending machine that does all those nasty things. And I think there are similar products already deployed.
fmntf··on Ryzen Boards Reign at Embedded World 2018
Have a look to the UDOO x86, which is made by SECO. (disclosure: i do some work for them)
fmntf··on Reach for Markdown, not LaTeX
Given how easy the markdown specs are, it is unbelievable how different the text is rendered using different engines.
fmntf··on Italian Anti-Corruption Authority Adopts Onion Services
Look at the form, they ask for you are you working, in which departments, etc.. It is just silly!
fmntf··on Italian Anti-Corruption Authority Adopts Onion Services
You are right in the first part (I'm italian). Regarding people doing a good job, I don't know if this is the case. I tried to use this service (just to see how it works), and:

  - "anonymous reports will be considered only in particular cases" (!)
  - you cannot report if you are a private person/company
  - you have no kind of legal counseling / protection
  - other limitations
I'm not sure if it was designed to get actual reports or not.
fmntf··on Key iPhone Source Code Gets Posted Online
It's just a bootloader. I don't think they changed much between iOS 9 and 11. The probably only added support for newer boards/devices.
fmntf··on Mozilla announces an open gateway for the internet of things
No no no. I am stating that, while TLS is good, your device will use other unprotected connections too (both on LAN and WAN) unless something else is done. until bugs or weaknesses are found, see SSL v1/2/3 deprecation, heartbleed, etc
fmntf··on Mozilla announces an open gateway for the internet of things
If you connected an IoT device in the same network of an infected PC, the infected PC can talk to the IoT device directly if you do not block traffic somehow (eg. a firewall). Are there open ports with buggy services? Probably not today, what about in ten years?

I'm on a different team, AFAIK we where using simple JSON payloads on websocket connections. Dropping websockets and switching to MQTT saved a lot of bandwidth. I can ask for precise numbers or details if you wish.
fmntf··on Mozilla announces an open gateway for the internet of things
So true. We switched to MQTT (abandoning websockets and other protocols) to save (a lot of) network bandwidth.
fmntf··on Mozilla announces an open gateway for the internet of things
I'm not sure what the original commenter meant; however TLS is useful only when talking with your own server. What about other connections? NTP, DNS etc are all unencrypted (read: unsigned). Google "DNS client CVE" for instance. Or what about SSH? It may not be accessible from the Internet, but still exploitable from an infected host in the LAN. Someone has to keep all that software updated. In those conditions, I would never connect a RaspberryPI or similar to my door / gate / car / ...
fmntf··on RFC: Ubuntu 18.04 LTS Minimal Images
Embedded systems. Smaller images take less time to be written on SD/eMMC devices.
fmntf··on LinuxBoot: Linux as Firmware
That's an edge case. Asserting that boot is typically 20 times faster is misleading.
fmntf··on Facebook open-sources Detectron
With such deep networks, I think it would be hard to get 3-5 FPS on an Intel iX; forget the Raspberry PI CPU!
fmntf··on Show HN: PlaidML, open source deep learning for any GPU
Nice! I will try it. Did you test the inference on Intel GPUs?
fmntf··on With Android Oreo, Google is introducing Linux kernel requirements
Unfortunately there is no binary compatibility between modules and different kernels. Moreover Google recommends CONFIG_MODVERSIONS=y, which prevents to load even practically compatible modules.
fmntf··on With Android Oreo, Google is introducing Linux kernel requirements
All the ARM boards i know share our same kernel issues. The problem is that DT is basically a configuration, which is accessed by drivers. If a driver do not read it, you must edit the driver. For instance a 2 lines patch [1] is about the fec (ethernet) driver. DT can specify a sleep time before the PHY reset GPIO is toggled. However we need to sleep also after the toggle, hence the patch.

fmntf··on With Android Oreo, Google is introducing Linux kernel requirements
I do not think it can be done. I am mantaining a kernel for ARM a family of SBCs. Device trees are great compared to old platform files, however they are not enough. We have a lot of commits to fix other things that DT cannot access.
fmntf··on It's Now Possible to Boot Android on I.MX6 Platforms Without Proprietary Blobs
I do some OSS development for UDOO, which sells iMX6 SBC (6Q, 6D, 6SX). We currently offer Android 6, I started to build 7.1 a few days ago. Intro end, question is, did you compare the performance between Vivante and OSS stuff?
fmntf··on Consider a Dell Optiplex FX160 Instead of a Raspberry Pi
Have you considered UDOO x86? It exposes GPIOs from an Intel braswell CPU and a microcontroller. (Disclosure: I do some software development for UDOO)
fmntf··on ASUS Launches Raspberry Pi-Esque 'Tinker Board' with 4K Support
Nice work! Have a look on udoo.org for more boards :-)
fmntf··on iPhone 5 web teardown: How Apple compresses video using JPEG, JSON, and canvas
If someone is interested in creating animations in this way, I created a simple script which converts videos in PNG/JSON/canvas:
