It’s a good time to work / collaborate remotely without traveling, or video chat with your loved ones to prevent the spread of the world-threatening Coronavirus (COVID-19). You can do this with the video conferencing server that I have presented to everyone in the link below.

On 2nd October 2019, Microsoft announced the new operating system, Windows 10X, in its Surface event.
Launched as a more modular version of the Windows 10 operating system, Windows 10X is not reported as a new version of 10, but rather as a variation for dual-screen hardware. The main objective of 10X is to use with touch screen devices such as tablets and smartphones.
Windows 10X Features
The biggest feature of the 10X is its dual display support, which allows two applications to run at the same time (if I remember correctly, the first company did this is Samsung with Note series smartphones). It also provides a different experience to the user as it can interact between these screens. In fact, the dual screen is a practice that has been used by people who have been using multiple monitors for a long time. Microsoft has now brought this vision to laptops and tablets.
In addition, Microsoft explained that the system resources are used more efficiently in Windows 10X (as they always state in their new OS releases).
10X offers a start screen just like in 10. In this menu,there are the installed applications, recently used files, and search features as you are familiar with. It is possible to go back to the desktop with the Windows logo at the bottom of the screen.
The first device to use the Windows 10X operating system was announced as Surface Neo. The Surface Neo is a laptop that basically combines two 9 inches touch screen displays with two hinges. Surface Neo with Intel processor can be used as a notebook with the Surface Pen. The externally mounted magnetic keyboard also offers a complete laptop experience.
The first hardware announced that will use Windows 10X operating system is Surface Neo. Other companies that will also produce such hardwares with dual screens are such as Asus, Lenovo, Dell and HP.
Will Existing PCs Work with Windows 10X?
Microsoft announced that 10X can be used on dual-screen devices such as Surface Neo. This means that this operating system cannot be used on existing PCs. In addition, 10X can be used only on devices with Intel processors. I think 10X can also be used (somehow) by plugging two screens into your existing equipment in the future.
We will see more clearly how Microsoft’s vision of this new operating system and hardware will make a sound in summer 2020. I hope that 10X will not share similar fate with previous Microsoft hardware and initiatives (like Zune and Windows Mobile).
As you know, Raspberry Pi came out as a simple mini computer designed to teach and endear children to coding. However, it has become a very versatile and popular device which can be used for many different purposes, especially for hobbyists.
Before the release of the Raspberry Pi 4, I have discussed the anticipated features of this mini computer in my previous article. This mini computer is now available and I will share my review of Pi 4 in this article.
Let’s now look at these components in more detail.
Processor and Memory
Raspberry Pi 4 is powered by Cortex-A72 architecture. Featuring a quad-core processor running at 1.5 GHz, the Pi 4 can decode H.265 in hardware. Of course, the high processing power comes with high temperature, and during my tests I found that if you are using Pi 4 in a box, the Pi 4 CPU temperature is around 60-65 degrees celcius. If you have a CPU-intensive application, the CPU can reach up to 90 degrees celcius. That’s why we’ll see fan-cooled Pi cases more often in near future.
Previous Raspberry Pi models have been available with 512 MB or 1 GB RAM for years, which can be a problem for some applications. The Raspberry Pi 4 now comes with three different memory options: 1, 2 and 4 GB. In addition, LPDDR4 technology has now been introduced.
Another part that has renewed in Pi 4 is the video outputs. The new Pi now has two Micro HDMI outputs, which are located on the old models HDMI port. You can use the Pi 4 as a powerful media device by connecting it to a television or monitor, with 4K 60 FPS dual video output capacity from both ports. In addition, you can do quite good visual applications such as digital signage and kiosk. For good display performance, increase the amount of GPU memory from the default value of 64MB to 512 MB by using raspi-config.
Network Connections and USB
The IEEE 802.11.b/g/n/ ac wireless network interface, which is introduced with the Raspberry Pi 3, is also available on the Pi 4 with a full-capacity Gigabit Ethernet port that communicates directly to SoC. Raspberry Pi 4 has now two USB 2.0 and two USB 3.0 ports with Bluetooth 5.0 BLE support.
As you can imagine, the power requirement of more powerful Pi 4 has increased. Assuming you’ll use a dual HDMI port with the USB components, you’ll need to use at least a 3A charger with the new Pi. If the USB peripherals consume less than 500mA in total, a good quality 5V 2.5A power supply can also be used.
Unlike previous models, the new Pi 4 has a USB Type-C port which is used for power input, but there are some problems due to a design error related to this port. Very roughly speaking, if you use high quality Type-C cables with a chip, the power adapter assumes Pi 4 as an audio device and refuses to give more power. You can solve this problem by using a low-quality Type-C cable. A very detailed article about the Type-C problem can be found here.
Comparison with Raspberry Pi 3 Models
When we compare Raspberry Pi 4 Model B with Pi 3 Model B+ which was introduced last year, we see that there are significant differences between them. The most important of these is the amount of CPU and RAM as you can imagine. With the Broadcom 2711 SoC, the new Pi 4 proves to be a highly performance computer with a nearly three times increase in performance compared to the Pi 3, and with three different RAM options which are 1, 2 and 4GB. Another important innovation is two Micro HDMI ports with 4K support. So now you have more options for your visual projects.
The following table details the main differences between the Pi 3 and Pi 4 models:
Because of the updated power input, HDMI and USB ports, the case design has changed. So if you’re going to use it with a box, you’ll need an up-to-date Pi 4 compatible box.
Raspberry Pi 4 Price
The Raspberry Pi Foundation has continued the fixed price policy tradition in this model too. It is possible to buy the starter version(1GB) for $ 35. Pricing for different RAM options can be found in the table below:
Amount of RAM
According to its website, Raspberry Pi 4 will remain in production until at least January 2026. So, like other Raspberry Pi’s, it seems to be a long-term computer as it’s predecessors.
