  • Blockchain Firm Offchain Labs Releases Alpha Of Open-Source Scaling Solution

    New Jersey-based Offchain Labs has announced the launch of the Alpha 2 version of its scaling solution that can be easily integrated to any Etherum application.

    Led by a former White House Deputy Chief of Technology and a team of U.S.-based academics, Offchain Labs aims to make smart contracts more private, secure, and scalable using a combination of protocol design, incentives, and virtual machine architecture. The firm has invented Arbitrum, a blockchain agnostic Layer 2 scaling solution that incentivizes parties to agree off-chain how a virtual machine would act in order to improve transaction throughput, speed, and privacy.

  • As Crypto Markets Go Cold, Who Will Pay for Open-Source Code?

    Earlier this year IBM purchased Red Hat, the oft-referred to model for how open source can thrive, for $34 billion.

    Long the consultant to enterprises, IBM is going through a transitional period as a business and needs a boost. Red Hat’s open-source software offers IBM the ability to better compete in cloud services offered by Amazon, Microsoft and Google.

    Why is this important? Red Hat is one of the most name-checked examples of how open-source software can be successful. It is often used as an example of how championing open source can lead to business success. This is particularly pertinent to the cryptocurrency ecosystem, where open-source ethos rule the technology.

  • Fridge0: an open source hardware solar fridge with no battery requirement

    Joey Hess designed the first Fridge0 a year ago: it uses a standard chest freezer with added thermal mass, a simple controller, and a photovoltaic panel that effectively stores sunshine as coldness, obviating the need for expensive backup batteries.

  • Open Source Smart Smoker Brings The Heat (Slowly)

    Conceptually, cooking on a grill is simple enough: just crank up the flames and leave the food on long enough for it to cook through, but not so long that it turns into an inedible ember. But when smoking, the goal is actually to prevent flames entirely; the food is cooked by the circulation of hot gasses generated by smoldering wood. If you want a well-cooked and flavorful meal, you’ll need the patience and dedication to manually keep the fuel and air balanced inside the smoker for hours on end.

    [...]

    Ultimately, this project boils down to tossing a bunch of temperature sensors at the problem. The software developed by [HackersHub] takes the data collected by the five MAX6675 thermocouples and uses it to determine when to inject more air into the chamber using a PWM-controlled fan at the bottom of the smoker. As an added bonus, all those temperature sensors give the user plenty of pretty data points to look at in the companion smartphone application.

Linux commands to display your hardware information

There are many reasons you might need to find out details about your computer hardware. For example, if you need help fixing something and post a plea in an online forum, people will immediately ask you for specifics about your computer. Or, if you want to upgrade your computer, you'll need to know what you have and what you can have. You need to interrogate your computer to discover its specifications. Alternatively, you could open up the box and read the labels on the disks, memory, and other devices. Or you could enter the boot-time panels—the so-called UEFI or BIOS panels. Just hit the proper program function key during the boot process to access them. These two methods give you hardware details but omit software information. Or, you could issue a Linux line command. Wait a minute… that sounds difficult. Why would you do this? Read more

BlackWeb 1.2

BlackWeb is a penetration and security testing distribution based on Debian. The project's website presents the distribution's features as follows: BlackWeb is a Linux distribution aimed at advanced penetration testing and security auditing. BlackWeb contains several hundred tools which are geared towards various information security tasks, such as penetration testing, security research, computer forensics and reverse engineering. Starting from an appropriately configured LXDE desktop manager it offers stability and speed. BlackWeb has been designed with the aim of achieving the maximum performance and minimum consumption of resources. There are 32-bit (x86) and 64-bit (x86_64) builds of BlackWeb available on the distribution's website. I downloaded the 64-bit build which is 2.6GB in size. Booting from the media brings up a menu asking if we would like to try BlackWeb's live desktop, run the installer or run the graphical installer. Taking the live desktop options presents us with a graphical login screen where we can sign in with the username "root" and the password "blackweb". Read more

Feh is a light-weight command-line image viewer for Linux

The default image viewer in most Linux distros is a fine option for many users, but if you want a distraction free alternative, Feh is a good option. Feh's interface is as barebones as it gets as it does not have any toolbars or buttons but is a command line interface application; because of that, it is very light on resources and still easy enough to use even for users who shy away from using the command line whenever possible.
