Human body activity associated with a task provided to a user may be used in a mining process of a cryptocurrency system. A server may provide a task to a device of a user which is communicatively coupled to the server. A sensor communicatively coupled to or comprised in the device of the user may sense body activity of the user. Body activity data may be generated based on the sensed body activity of the user. The cryptocurrency system communicatively coupled to the device of the user may verify if the body activity data satisfies one or more conditions set by the cryptocurrency system, and award cryptocurrency to the user whose body activity data is verified.

Guest Post: Path-aware architectures are showing potential as means to improve efficiency and solve many of the security issues of today’s Internet.

Пусть надо мной посмеются сетевые инженеры в больших интеграторах, у которых есть доступ к топовому оборудованию за кучу килобаксов. Я хочу рассказать о том, как...

На странице представлено сравнение коммутаторов различных производителей. В таблице указаны пакетный буфер и ASIC на котором построен коммутатор.

The COVID-19 pandemic and the resulting economic shutdown have been detrimental to many industries and companies around the world. A reported 60% of businesses that closed due to the pandemic are now permanently closing as business owners have struggled to make ends meet during this unpredictable time. But not all companies have been struggling: Some […]

Developer Alexander Graf has successfully virtualized the Arm version of Windows on an M1 Mac, proving that the M1 chip is capable of running...

At Cloudflare, we pride ourselves in our global network that spans more than 200 cities in over 100 countries. To accelerate all that traffic through our network, there are multiple technologies at play. So let’s have a look at one of the cornerstones that makes all of this work.

Мы постоянно тестируем новые решения для наших проектов и недавно решили разобраться, что под капотом у Cisco Umbrella. Сам вендор заявляет, что это облачное реш...

In this post, we'll walk through upgrading a Cisco SD-WAN (Viptela) network, including controllers & WAN edge devices.

In a previous blog on Getting Started with Modern Data Center Fabrics, we discussed the common modern DC architecture of an IP fabric to provide base connectivity, overlaid with EVPN-VXLAN

Let's Encrypt is an amazing organisation doing an amazing thing by providing certificates at scale, for free. The problem though was that they were the only such organisation for a long time, but I'm glad to say that the ecosystem is changing.    It's always a good idea to have another

I have in my short WiFi life thought when an 802.11 station (WiFi) does carrier detect it would detect all parts of an ongoing frame transmission on the channel and defer its own transmission becau…

If you think about all the core concepts of wireless communications, detecting whether you are receiving a signal or just noise is the most fundamental operation which triggers the various processes in the receiver, not only for the reception of frames but this also helps to implement spectrum sharing protocols based on listening before talk approach. The basic idea (Clear Channel Assessment -CCA) is simple but 802.11 and 3GPP standards (unlicensed bands) have evolved over years to add many variants to it with the tradeoff of backing off vs reuse, understanding the differences among them, and when to use what is crucial to understand this key concept of wireless communications. As some standards push wireless communications to its maximum limits other standards aim at improving spectral efficiency which focuses on more practical problems than getting the best performance in a laboratory.

Microsoft is reportedly creating a subsystem, similar to the Windows Subsystem for Linux, that allows Android applications to run on Windows 10.
