It connects the observation to the known monitor-eavesdropping technique called van Eck phreaking and explores whether the emissions can transfer additional information. ### Source excerpt This story, too, begins with noise. I was browsing the radio waves with a software radio, looking for mysteries to accompany my ginger tea. I had started to notice a wide-band spiky signal on a number of frequencies that only seemed to appear indoors. Some sort of interference from electronic devices, probably. Spoiler alert, it eventually led me to broadcast a webcam picture over the radio waves... but how? It sounds like video The mystery deepened when I listened to how this interference sounded like as an AM signal. It reminded me of a time I mistakenly plugged our home stereo system to the Nintendo console's video output and heard a very similar buzz. Am I possibly listening to video? Why would there be analog video transmitting on any frequency, let alone inside my home? If we plot the signal's amplitude against time we can see that there is a strong pulse exactly 60 times per second. This could be the vertical synchronisation signal of 60 Hz video. A shorter pulse (pictured above) can be seen repeating more frequently; it could be the horizontal one. Between these pulses there is what appears to be noise. Maybe, if we use the strong pulses for synchronisation and plot the amplitude of that noise as a two-dimensional picture, we could see something? And sure enough, when main screen turn on, we get signal: (I've hidden the bright synchronisation signal from this picture.) It seems to be my Raspberry Pi's desktop with weirdly distorted greyscale colours! Somehow, some part of the monitor setup is radiating it quite loudly into the aether. The frequency I'm listening to is a multiple of the monitor's pixel clock frequency. As it turns out, this vulnerability of some monitors has been known for a long time. In 1985, van Eck demonstrated how CRT monitors can be spied on from a distance[1]; and in 2004, Markus Kuhn showed that the same still works on flat-screen monitors[2]. The image is heavily distorted, but some shapes and even bigger text can be recognisable.

Existing v22.06 users receive the service pack automatically through system updates. ### Source excerpt Here it is, after a bit of delay to figure out why the new Phosh version didn't boot on the Samsung Galaxy S III. Now that the reason is known and a workaround is in place, we also happened to hit the timeframe where fixup versions of these huge Phosh and Phoc releases were made. Enjoy the following changes on stable! Contents Phosh 0.21.0 and Phoc 0.21.1 are huge upgrades from the previous versions 0.17.0 and 0.13.1. Both skipped a lot of version numbers to 0.20.0 in case you are wondering. Most excitingly it is now possible to swipe up and down to make menus show up. Also the lockscreen has been reworked, it's now possible to use the top menu there and for everyone who configured Phosh with pmOS tweaks to show the battery percentage, you will be able to see that right on the lockscreen too. See the changelogs of (Phosh) 0.20.0 (and the 3 betas linked there), 0.21.0 and (Phoc) 0.20.0, 0.21.0, 0.21.1 for a detailed list of changes. postmarketOS-welcome 0.6.0 informs about how menus are now opened in Phosh (so users who did not read this blog post are not confused). Also the logic was changed to make it show up once when booting into this new Phosh version. linux-postmarketos-qcom-sdm845 5.19.0 is a well-tested upgrade from edge for the SDM845 based SHIFT6mq, OnePlus 6/6T and Xiaomi Pocophone F1. powersupply 0.8.0 (previously 0.6.0) is relevant for the SDM845 SoC as well, as it brings the necessary quirks to show the charging/discharging rate, temperature and USB current limits for SDM845 too. PinePhone Pro now has a workaround to fix audio if not having proper SMBIOS information coming from the bootloader (pma#1601). This was properly fixed in Tow-Boot 2021.10-005. PinePhone: kernel upgrade to 5.19.2 and the AF8133J magnetometer driver is now enabled PinePhone (Pro): add the upower fwupd plugin to prevent (modem firmware) upgrades if the phone is not connected to AC (pma!3320) Samsung Galaxy S III: HDMI out had to be disabled as the kernel driver reports the wrong s ## JPEG Is a Family of Formats With Different Decoding Requirements DevFeed: [JPEG Is a Family of Formats With Different Decoding Requirements]() Original publisher: [Read original article]() Author: ben@benjojo.co.uk Published: 2021-11-19T10:47:26Z Content type: article Language: en Sources: [benjojo blog]() Topics: [Encoding](), [format](), [Compression](), [Decoding](), [Hardware](), [Software](), [hdmi](), [intel]() Tags: [compression](), [decoding](), [encoding](), [format](), [hardware](), [hdmi](), [intel](), [software]() ### AI overview An exploration of JPEG as a family of formats rather than a single uniform format, focusing on hardware and software decoding, compression, and a failed attempt to transmit JPEG data through HDMI equipment. ### Source excerpt One of these JPEGs is not like the other "JPEG" or the image encoding specification by the "Joint Photographic Experts Group" (JPEG) is a truly universal format at this stage.

It describes Phosh, phone functionality, optional full-disk encryption, hardware support, USB-C dock connectivity, pricing, configurations, and preorder availability. ### Source excerpt We are absolutely thrilled to announce that Pine64 is releasing a Mobian Community Edition of the PinePhone! This is a major milestone for our project, which started less than a year ago as a way to bring Debian to this exact mobile device! A Debian computer in your pocket The PinePhone is basically a handheld computer with 4G connectivity. With Mobian, this (truly smart) phone comes with a distribution tons of Debian users are already familiar with, optimized for the PinePhone while still giving them access to the 50,000+ packages already in the Debian archive. Mobian ships with Phosh, a mobile-oriented desktop environment based on GNOME technology, initially developed by Purism for their Librem 5 smartphone. Default applications have been selected for their usability on a phone-size display wherever possible, and we're confident this list can only grow over time. Combined with the absence of software trackers, this gives you an ad-free, privacy-respecting platform you can bring anywhere with you and use the same way you do with your personal computer. Taking it to the next level, plug in a USB-C dock connected to a keyboard, mouse and HDMI monitor, and you won't be able to tell if you're using a phone or a "regular" computer. What to expect When first powering on your PinePhone Mobian Community Edition, you'll be greeted with an installer, allowing you to choose your user password and presenting you with the ability to enable full disk encryption. Hardware support is pretty much complete, and while it still needs to be refined in a number of areas, you'll be able to enjoy full phone functionality (including voice calls, SMS, mobile broadband, WiFi, front and back cameras...) from day one. However, please note the software is still mostly work-in-progress, and evolves on an almost-daily basis. Your device will arrive with a several months old image, so we can only recommend that you update your PinePhone as soon as possible to take advantage of the latest development ## KDE Community Edition is now available DevFeed: [KDE Community Edition is now available]() Original publisher: [Read original article]() Published: 2020-12-01T00:00:00Z Content type: release Language: en Sources: [Community blog on PINE64]() Topics: [Pinephone](), [Mobile](), [Linux](), [Hardware](), [USB](), [Ethernet](), [hdmi]() Tags: [community-edition](), [ethernet](), [hardware](), [hdmi](), [kde](), [linux](), [mobile](), [pinephone](), [usb]() ### AI overview PINE64 announces that the KDE Community Edition PinePhone is available for pre-order.
