heise + | Linux mobile operating system Jolla Sailfish OS 3.4 with multi-user operation in the test

Linux mobile operating system Jolla Sailfish OS 3.4 with multi-user operation in the test Browser engine for apps Updates for developers Article in c’t 24 / 2020 read Jolla has released version 3.4 of its Linux-based mobile operating system under the name of the Finnish National Park Pallas-Yllästunturi. For the first time, you can create up to six additional user accounts in Sailfish OS 3.4. These are restricted and cannot be used to install or remove apps; Android apps cannot even be run at the moment. The main user can also deactivate their access to telephony and SMS. The language can be freely selected for each account. But it is incomprehensible that WLAN networks are also managed separately for each account.

Despite these restrictions, the new multi-user operation can be used to isolate private and professional activities, as all configurations are saved separately with native Sailfish apps. E-mail accounts for work can be created under a special work account. If you switch to the private profile, only private e-mail accounts are integrated. Every user must assign a PIN. In addition, fingerprints for unlocking can be stored for each user. The user account can be changed during operation via the system menu, which can be called up with a swiping gesture from the top of the screen.

Multi-user operation is not yet fully developed and its use currently seems to be primarily aimed at corporate customers. With one of the upcoming updates, Android apps should also be usable in the additional accounts.

250-euro-notebook-at-aldi:-amd-zen-processor,-ssd-and-usb-c

250 euro notebook at Aldi: AMD Zen processor, SSD and USB-C

From 26. November 1920 Aldi Süd sells the entry-level notebook Akoya E 15308 For 250 Euro. The price requires compromises in the equipment, which is better than other devices in this class.

The heart of the Akoya E 15308 forms the AMD processor 3020 e (without Ryzen or Athlon add-on) with two Zen cores (1.2-2.6 GHz) and a Radeon Vega graphics unit with 192 Shader units. The Thermal Design Power (TDP) is kept very low at 6 watts, but the processor does not use simultaneous multithreading (SMT), so it can only process two threads. Manufacturer Medion pairs the 2400 e-CPU with 4 GByte DDR4 – 2400-R.A.M. Although the memory interface can handle dual-channel RAM, Medion soldered the RAM in single-channel.

On a 71 GByte SSD is Windows 10 Home in the S -Mode pre-installed that allows the installation of apps from Microsoft’s Windows Store. Another SATA 6G data carrier can be installed in a 2.5-inch slot. The 15, 6 inch IPS display represents 1920 × 1080 pixels – atypical in this price range. There are reductions in brightness (198 cd / m²) and the color space coverage ( Percent NTSC).

Medion Akoya E 15308 ( 4 pictures) (Image: Medion) USB-C with DisplayPort 1.2 and charging function A USB 3.2 Gen 1 (5 GBit / s) with Type-C connection controls an Ultra-HD in DisplayPort 1.2 Altmode -Monitor (3840 × 2160 pixels) with 60 Hertz. Devices can also be charged via the Type-C port via Power Delivery. There are also USB 2.0 Type A, HDMI (presumably 1.4), an audio combo jack and a micro SD card reader. The Akoya E 15308 transmits in Wi-Fi 5 networks (WLAN 802. 11 ac) and with Bluetooth 4.2.

The upper casing of the notebook is made of aluminum. With a size of 359 mm × 192 mm × 24 mm weighs the Akoya E 15308 just under 1.8 kilograms.

Aldi Nord currently has no plans to include the device in its own range. If you look in the price comparison for notebooks with at least 13, 3 inch display, full HD resolution and 250 cd / m² brightness, only a few models are available for less than 300 euros to be found. All are Chromebooks with slower processors, such as Atom dual cores from Intel and AMD’s old Bulldozer combination processors. They also use 32 to 64 GByte eMMC flash memory instead of an SSD.

schenker-vision-15:-the-notebook-that-intel's-nuc-department-helped-develop

Schenker Vision 15: The notebook that Intel's NUC department helped develop

Schenker has the Ultrabook Vision 15 announced that with Intel 10 – Nanometer top model Core i7 – 1165 G7 from the Tiger-Lake-U family with a large battery appears. Intel’s NUC department, which among other things designed the mainboard, took part in the design. The latter should enable a low idle power consumption of 3 watts.

The Core i7 – 1165 G7 runs in Vision 15 with a Thermal Design Power (TDP) of 20 Watt, so that the four CPU cores can run at high clock frequencies (nominally 2.8 up to 4.7 GHz). The integrated Xe graphics unit is also used – Schenker dispenses with an additional graphics chip.

The 73 Wh strong battery should be at 150 cd / m² display brightness for 14 hours of surfing on WiFi or 14 Hours of video playback (H. 264 Codec) are sufficient. The aluminum housing can be opened to replace the battery – internally it is screwed, not glued. The 15, 6 inch IPS display represents 1920 × 1080 pixels (Full HD), lights up at the top with high 450 cd / m² and can handle touch inputs. The SRGB color space should be at least 71 Cover percent.

Schenker Vision 15 (13 Photos) (Image: Schenker) Thunderbolt 4 with DisplayPort 1.4 The battery is charged via one of the two Thunderbolt 4 ports in the form of USB-C ports, which are located on the left and right – one 65- Schenker includes a watt power supply with quick charge function. In addition, the Thunderbolt 4 ports transmit data with 031 GBit / s (USB 4.0 Gen 3×2) and a DisplayPort 1.4 signal for connecting monitors that are compatible with Ultra HD (3840 × 2021 pixels) at up to 144 Hertz is enough. There are also two USB 3.2 Gen 2 Type A (10 Gbit / s), HDMI 2.0 and an audio combo jack ready.

It works wirelessly Vision 15 in the Wi-Fi 6 network (WLAN 802. 11 ax) and with Bluetooth 5.1. The notebook is about 355 mm × 150 mm × 15 mm tall and weighs 1 ,68 Kilogram.

pre-orders for the Vision 15 Schenker will take over its own online shop from December 4th 2020 – the delivery should start at the end of January 2021. The basic configuration with 16 GByte soldered, but fast and economical LPDDR4X – 4266 – RAM as well as 250 GByte PCI Express 3.0 SSD (Samsung SSD 970 Evo Plus) costs 1500 Euro. Upon request, customers can choose larger and faster SSDs, including Samsung’s 980 Pro with PCIe 4.0.

Schenekr’s sister company Tuxedo will be a Linux version of the Vision 15 as InfinityBook Pro 15 bring Gen6.

linux-handy-pinephone:-new-variant-with-kde-plasma-mobile-announced

Linux-Handy PinePhone: New variant with KDE Plasma Mobile announced

The manufacturer PineMicrosystems presents another variant of the PinePhone. The Linux smartphone is delivered with Plasma Mobile, the mobile version of the KDE Plasma Desktop. The PinePhone in the “KDE Community Edition” is aimed primarily at developers and community members.

According to an article in Pine 64 – Blog, the “PinePhone KDE Community Edition” can be pre-ordered from December 1st. The device is available in two different hardware versions: The basic model has 2 GB RAM and a 16 GB eMMC module as main memory for 149 USD. The “Convergence Package” contains the device with 3 GB RAM and 16 GB eMMC module as main memory, as well as a USB-C dock for convergence Modus and costs 199 USD.

If you already own an older PinePhone, you can purchase the Community Edition mainboard and upgrade it yourself. Buyers of the “Braveheart” or “Ubports” edition get a cheaper offer.

A look into the future? The target group of the PinePhone “KDE Community Edition” includes intrepid people and developers. Basic functions of a smartphone can be used, such as making calls, SMS, web browser and the camera. Pine 64 does not recommend the device for productive use.

Enthusiasts or users who value privacy may still opt for the PinePhone. Switches for deactivating the camera, microphone, WLAN and mobile data can be found under the battery cover. Pine 64 is pursuing the goal of providing feedback to the development teams with the community editions and offering smartphone hardware to the respective projects that can run mainline Linux.

The smartphone as a desktop replacement Plasma-Mobile comes from the Linux desktop environment of the KDE project. The mobile user interface shares the basic libraries and technologies with the plasma desktop. Those who use the plasma desktop will find familiar applications such as the document viewer Okular or the VVave music player on the Pinephone “KDE Community Edition”.

If you connect the Pinephone via a USB-C -Dock with monitor (or TV), mouse and keyboard, switches the phone to convergence mode. The user interface then changes from portrait to landscape mode and is ready for use as a mobile workstation. According to the announcement of the new PinePhone on the KDE website, the modern UI frameworks Kirigami and Maui enable great advances in the development of platform-independent software. Apps such as clocks, calendars and games adapt flexibly to the respective display conditions.

KDE Plasma Mobile’s turn The “KDE Community Edition” of the PinePhone follows the other already published PinePhone editions. The device was previously available with the community editions Ubports (Community Fork of Ubuntu Touch), Manjaro and Postmarket OS. For every PinePhone sold in the community versions, the manufacturer donates 10 US dollars to the respective development teams.

You can find out more about the “PinePhone KDE Community Edition” in the Pine blog 64 and on the KDE project website. If you want to follow the development progress of Plasma Mobile, you will find it in the blog of the development team.

heise + | IOT hacking: replay attacks via radio

IOT hacking: replay attacks via radio Much not encrypted Tools for the 433 – MHz standard Several paths lead to the bit stream Conclusion Article in iX 12 / 2020 read With wireless networks, data traffic can be recorded and manipulated even without direct access, provided the attacker is within their range. In addition to the ubiquitous WLAN standard, wireless technologies such as Bluetooth Low Energy, GSM / GPRS and ZigBee are also used in IoT devices. Often proprietary protocols are also used in the ISM band with, for example 433 or 868 MHz used. This article gives an insight into an attack on an IoT device via the 433 – MHz standard.

The identification and recording of wirelessly transmitted data does not require expensive equipment, because Much of the radio signal processing can now be done using software. Such software-defined radios perform a large part of the signal processing on an ordinary computer.

The reception and recording of all radio signals of the IoT standards used are handled by inexpensive devices such as Nooelec’s NESDR SMArt v4 (from 31, 95 €), which is used for this article.

Smart monitors: Samsung displays with ARM processor, WLAN and Tizen

Samsung has announced the two monitor series M5 and M7, which the manufacturer calls smart monitors, analogous to smart TVs. For this, Samsung has placed a small, economical ARM processor in the display and installed its own Tizen 5.5 operating system. This allows users to watch video-on-demand services such as Amazon Prime Video, Netflix or YouTube without a connected PC. Office 338 applications can also be started.

Three displays make the start: The 32 M 70 A is 32 inches tall and solves with 3840 × 2160 pixels (Ultra HD ) at 60 Hertz. The M5 series consists of one 27 – and 32 – Zöller with lower Full HD Resolution (1920 × 1080 pixels). Samsung relies on VA panels, the backlighting of which with 71 cd / m² is quite low fails. The response times are also rather slow at 8 ms (GtG).

The manufacturer provides the M7 and M5 monitors for the home office. During the day, users can connect their PC and work on it; Watch your favorite series in the evening without having to run your PC. This only makes sense if you don’t already have a smart TV.

Samsung 32 M 70 A (9 pictures) (Image: Samsung) Smart Hub or DeX surface The Smart Hub interface is known from Samsung’s Smart TVs. Alternatively, “DeX” represents a PC-like interface in which a Galaxy smartphone or tablet is wirelessly connected to the monitor and serves as a data center. Apple’s AirPlay 2 is also on board. Two 5-watt speakers reproduce stereo sound.

The Smart- Monitors via Wi-Fi 5 (WLAN 696. 11); Peripherals can also be connected via Bluetooth 4.2. The USB-C port is useful, which connects a notebook with up to 70 Charges watts, accepts a DisplayPort 1.2 signal and transmits data. Alternatively, the displays come with HDMI 2.0 – there are no separate DisplayPorts. A remote control including Bixby voice control is included.

Samsung wants the M7 and M5 monitors from the end of November 2020 deliver to countries outside of North America and China.

heise-+-|-tutorial-for-beginners:-easily-implement-iot-projects-with-espeasy-firmware

heise + | Tutorial for beginners: Easily implement IoT projects with ESPEasy firmware

Many IoT projects with the ESP 8266 do not need sophisticated programming. ESPEasy is easy to install and offers tons of customization options.

Tutorial for beginners: Easily implement IoT projects with ESPEasy firmware Preparation Installation sensors Regulate MQTT Article in c’t 24 / 2020 read The popular WLAN microcontroller ESP 8266 is in all of them d devices such as switch sockets and LED lamps, but it is also an inexpensive and easy-to-program candidate for self-constructed Internet of Things (IoT) projects. The firmware projects Tasmota and Espurna are particularly popular; they remove finished smart home actuators from the manufacturer cloud in just a few steps so that they can be integrated into local smart home management using protocols such as MQTT.

The projects support many devices out of the box with finished profiles so that you no longer have to worry about GPIOs and drivers. However, both are primarily designed to execute received commands, and less to control logic that runs directly on the ESP. That makes Tasmota and Espurna only of limited interest for their own projects or self-sufficient smart home devices.

But thanks to ESPEasy you don’t have to delve into the depths of C programming yourself: The open source firmware is just as easy to install as Tasmota and Espurna, but offers more flexibility in terms of the sensors and protocols used and even its own set of rules with which you can teach the ESP logic, for example to switch a switch socket using a soldered-on sensor depending on the room temperature. ESPEasy has a web interface through which all settings can be changed remotely. This saves valuable time that you would otherwise have to invest in programming and debugging.

worldwide-youtube-outage-at-us-prime-time

Worldwide YouTube outage at US prime time

A US prime time outage of more than an hour on YouTube shocked users worldwide. Many initially suspected a problem with their WLAN or Internet provider, but according to information from heise online it was a failed configuration update of the Google server that made the user look down the drain in the figurative sense.

The problem occurred early Thursday morning around 1: 15 Clock German time presumably worldwide, we were able to verify the failure in North America, Europe, Asia and Australia. While the web servers continued to work without any problems, so that the entry page, the search function, channel pages and also YouTube Studio were still available and functioning normally, no more videos could be played.

All videos from the platforms YouTube Video, YouTube Music and YouTube TV were affected. YouTube confirmed the problem for YouTube Video after a few minutes on its Twitter channel, and almost an hour later also explicitly for the YouTube TV platform, although, according to our research, no more videos could be viewed there from the start.

Redirects An analysis carried out by heise online during the incident revealed that Google had a problem with the redirector of its video platform googlevideo.com would have. The redirector is responsible for redirecting the player to the actual storage location of the video file via HTTP status code 15 (“Moved Temporarily”). Apparently the redirector could no longer access its video database and only provided the HTTP status code 502 (“Bad Gateway”) for more than an hour. Users only saw black or, if an ad was to be displayed, an indefinite error message on a dark gray background.

For YouTube Content Creators is not only able to see the downtime of more than an hour in the access statistics, it is also immediately reflected in their income.

The Google employees only succeeded after almost two hours to fix the problem. The incident cost content creators with a predominantly American audience a lot of money that they would normally have earned at prime time from access by their viewers – the break-in can be clearly seen in YouTube Analytics.

Google has not yet made any cause Information. As heise online learned from a trustworthy source, a configuration update was introduced at Google at the same time (“configuration push”), which obviously went wrong and could not be easily reversed. At three o’clock German time, YouTube was back on track. (mid)

mac-computers-with-arm-processors:-wi-fi-6-and-6k-support-for-everyone

Mac computers with ARM processors: Wi-Fi 6 and 6K support for everyone

With the new ARM chip M1, functions come to the Mac that Intel machines have so far lacked. As the specifications of MacBook Air, MacBook Pro with 09 – inch screen and Mac mini can be seen, all three computers support Wi-Fi 6 for the first time. The improved WLAN standard has so far only been used by iOS devices like the iPhone SE 2020 and the iPad Pro of the year 2020 used but not by macOS machines.

Fritz boxes at the start Wi-Fi 6, as IEEE specification 802. 11 called ax, offers a maximum possible throughput rate of 1.2 Gbit / s on Apple devices, provided there is a suitable base station in the house. Backwards compatibility to 802. 11 a / b / g / n / ac is of course given.

Wi-Fi 6 is becoming more and more popular; AVM recently equipped its first DSL router with the technology. The Fritzbox 7530 will be available from November after it has already been used with the Fritzbox 6660 had given a Wi-Fi 6-enabled cable box. The successor to 802. 11 ac delivers under optimal conditions 37 Percent more bandwidth.

6K of all new Macs Also very useful is the fact that all three M1 Macs now support 6K output on the Pro Display XDR. For the entry-level MacBook Pro with 11 – Inch screen is a novelty – the Intel variant with two Thunderbolt 3 ports, which it replaces, has not yet been able to do this. The current Mac mini with Intel chip also only managed a 5K speech. The last MacBook Air with an Intel processor, on the other hand, was able to work with the Pro Display XDR.

M1: The CPU of the Apple Silicon Macs (4 images ) Apple Silicon : The new Macs are powered by Apple’s M1 CPU with up to 8 cores, 4 of which are particularly energy efficient.

Own GPU cores make it possible According to Apple, the M1 chip in the new Macs delivers, among other things, six times faster GPU performance – thanks to graphics cores developed in-house – compared to Intel models and up to 3.5 times faster overall CPU performance. The battery life is also said to have improved significantly. Intel code runs on the new Rosetta 2 translation framework; there are even supposed to be cases in which this emulation executes code faster than natively on Intel Macs.

various-improvements:-avm-publishes-a-new-laboratory-version-for-the-fritz!-box-7590

Various improvements: AVM publishes a new laboratory version for the FRITZ! Box 7590

AVM has a new laboratory version with the version number 07. 16 – 83272 for the FRITZ! Box 7590 released. With the update, users are now able to prefer individual network devices. In addition, if the primary Internet connection fails and the extended failure protection is subsequently activated, support data can now be transferred to AVM again. In addition to the improvement of the auto channel function after detection of sources of interference (5 GHz band), there is also a new message under “System / Events” when the maximum number of WLAN repeaters is exceeded.

In the Telephony area, the “E-Mail” and “RSS” tabs in the “Telephony / Telephony Devices” menu can now be hidden if DECT is switched off. The presentation and management of entries in telephone books has also been completely revised. The settings for sending and receiving faxes have now been combined under “Telephony / Telephony Devices”. In addition, it is possible to resend support data to AVM with the new laboratory version after the sending process has been completed without waiting.

As before, this update is a beta version. AVM points out that the firmware was tested in various standard environments before it was released. However, it is possible that it may malfunction after installation. The company assumes no liability for any damage resulting from the use of the laboratory version. However, users are always able to switch to the official FRITZ! OS software under System> Update> FRITZ! OS version.

If you already have a laboratory version on your FRITZ! Box 7590 receives the update via the router’s user interface. A manual download can be found on the official AVM website.
