Best Budget Chia Farming Rig

Filed under

Of course, there are a lot of other budget Chia farming rig options if you have your heart set on farming on a low-power platform. The Raspberry Pi costs less (eBay Raspberry Pi4), but requires assembly and really doesn’t have much power to farm at scale. For a processor it uses a Broadcom BCM2711, Quad-core Cortex-A72 (ARM v8) 64-bit SoC (up to 1.5GHz), it can have 4GB of RAM (or up to 8GB) and has four USB ports. It is one-sixth (though kits cost more) the price of the Nano but doesn’t come with storage (users can add it via microSD card or through the USB ports). The Raspberry Pi also definitely cannot plot Chia with any reasonable efficiency.

Intel NUCs can be another option, but they have different issues. Primary amongst them is they’re often more expensive than the Nano and have less expandability. On the lower end of the cost spectrum, the NUCs are either a kit like just a board, are missing storage, or feature HDDs. In fact, to match the specs of the Lenovo Nano you would be up around the $300 price range for a refurbished NUC and you still wouldn’t have the ports, USB, or dual network.


We have Ubuntu 20.10 installed on the M90n-1. If you are new to installing Chia Blockchain, there is a handy how-to guide that can be found here. The guide tells you what you need in terms of minimum specs for your system, and goes through over six different types of systems. As said, we are using Ubuntu here we used the CLI tool and followed the step-by-step instructions listed on the Chia INSTALL page. The whole process was fairly easy and was completed in less than 10 minutes.

  • Security updates for Wednesday

    Security updates have been issued by Debian (cgal, exim4, and mediawiki), Fedora (axel, libmicrohttpd, libtpms, perl-Image-ExifTool, pngcheck, python-yara, and yara), Gentoo (exim), Mageia (kernel-linus), openSUSE (bind and postsrsd), SUSE (avahi, openexr, p7zip, python-Pygments, python36, samba, sca-patterns-sle11, and webkit2gtk3), and Ubuntu (nvidia-graphics-drivers-390, nvidia-graphics-drivers-418-server, nvidia-graphics-drivers-450, nvidia-graphics-drivers-450-server, nvidia-graphics-drivers-460, nvidia-graphics-drivers-460-server).

  • Drop telnet for OpenSSL |

    Due to telnet's lack of encryption, it has largely been replaced by OpenSSL for this job. Yet telnet's relevance persisted (and persists in some cases even today) as a sort of intelligent ping. While the ping command is a great way to probe a host for responsiveness, that's all it can do. Telnet, on the other hand, not only confirms an active port, but it can also interact with a service on that port. Even so, because most modern network services are encrypted, telnet can be far less useful depending on what you're trying to achieve.

  • 2FA and Recycled Phone Numbers Are a Security Risk [Ed: 2FA is oftentimes just overhyped junk, as many security experts have long warned]

    Two-factor authorization is supposed to lead to increased security. That extra step is supposed to prevent spammers from breaking into your account. By just learning one access point, they are still required to take an extra step that they most likely do not know.

LibreOffice: Making a Globe and Bibliography Improvements

  • 3D Objects: Making a Globe with LibreOffice

    In the dialog box that appears, click on “Bitmap” and then on “Add/Import”. Select the downloaded map, and enter a name for it, that you will use in your collection of bitmaps. The image should be applied to the sphere. If not, select the map from the collection.

    Then, in the “Options” part of the dialog box, select the item “Stretched” from the drop-down list “Style”. Click OK. Your globe is finished!

  • Bibliography improvements in LibreOffice Writer: refer to a specific page

    The bibliography feature in Writer allows authors of e.g. scientific papers to track sources: first you can insert bibliography entry fields, then at the end you can generate a bibliography table automatically.

    Writer recently gained two improvements in this area, and now there is one more: the ability to refer to a specific page of a (potentially long) source.

    First, thanks TUBITAK ULAKBIM who made this work by Collabora possible.

  • Router Freedom: Greece one step forward - Germany one backward

    EU member states are updating their legislation and implementing rules on Router Freedom. Greece and Germany have taken the first steps. But while Greece has focused on interests of end-users, Germany has moved in the opposite direction. The next months are crucial for Router Freedom in Europe and local participation is paramount.

    Telecommunications law in the EU is passing through complex legislative reforms, involving, among others, supra-national institutions like BEREC, member states' parliaments and national regulatory agencies (NRAs). Since December 2020, EU member states have started legislative processes to implement the European Electronic Communications Code, or EECC (Directive (EU) 2018/1972), a key component of the reform, which sets new standards for Router Freedom.

    Greece and Germany were the first EU countries to incorporate the EECC into national legislation. Now, the national regulatory bodies of both countries will have to decide on rules that will impact the status of Router Freedom in their jurisdictions. The FSFE has been following closely the new developments and took part in consultative processes. In addition, we have prepared an activity package to help local communities engaging with their national regulatory bodies.

  • Upgraded becky to Raspberry Pi 4 4GB

    It seems I have built my Raspberry Pi server named becky just last year, but it’s actually been around for over 5 years, so when opportunity presented itself I decided to upgrade it.

    becky is one of the many Raspberry Pi systems I have around my home office, it’s the one that uses official Raspberry Pi 7” screen that is just big enough to keep tmux session and stream latest critical logs from my centralised RSyslog setup.


    Finally I booted the system and realised it’s not going to work off the microUSB cable anymore - not enough power, as confirmed by the console messages:

    After switching to USB-C power everything worked fine (even though I used old enough Raspberry Pi power supply that provides only 2A).

    becky is a lot more powerful now, with plenty of RAM and CPU power.

    I’ve taken time to switch Raspberry Pi 4 to 64bit kernel already, but will probably do a full reinstall at some point.

  • SigmaStar SSC33x Camera SoCs are pin-to-pin compatible with Hisilicon Hi3516/Hi3518 processors

    There’s very limited public information about the chips, at least in English. The Linux SDK and DLA SDK can be acquired from SigmaStar after signing an NDA. BR16 lists some SSC33x modules and expensive development boards, but SigmaStar SS336D/SSD336Q camera SoC itself can also be purchased on Taobao for 49.5 RMB (about $7.6 US), while an SSC338Q module is offered for 108 RMB (~$17.6 US).

Kernel Work: Intel and VMware

  • Linux 5.13 Adds An Intel Cooling Driver To Downclock Your CPU At A Lower Threshold - Phoronix

    Linux 5.13 is introducing the "intel_tcc_cooling" driver for helping to cool newer Intel mobile/desktop CPUs by down-clocking the processor cores when crossing a lower threshold than is set by default.

    This new driver for Linux 5.13 allows setting a lower threshold / offset for the Thermal Control Circuit (TCC) activation temperature. Rather than waiting until the default TCC activation temperature is reached, Intel CPUs support applying an offset (the "TCC Offset") via an MSR if wanting to set the down-clocking to occur at a lower temperature over the default system critical temperature.

  • Intel Explores Write Protecting Page Tables Using Upcoming PKS Feature - Phoronix

    As an additional security measure for the Linux kernel, Intel engineers are exploring making kernel page tables read-only and to then only allow writing on a per-CPU basis when they need to be modified. This would be handled using the PKS functionality found with future Intel processors.

    For many months now Intel has been working on the infrastructure for Protection Keys for Supervisor support in the Linux kernel. Protection Keys for Supervisor (PKS) is coming with future Intel processors. PKS as the supervisor/kernel equivalent to the existing PKU functionality was initially prototyped as a way to prevent stray writes to persistent memory and safeguarding trusted keys within the Linux kernel. A new proof-of-concept posted on Tuesday would be using PKS for safeguarding page tables.

  • VMware Prepares Linux Driver For Next-Gen Virtual GPU - Phoronix

    While physical GPUs may be in short supply right now, VMware is preparing for "SVGA v3" as their next-gen virtual PCI graphics adapter for use within VMware virtual machines for graphics acceleration backed by the host. 

    VMware has long provided reliably Linux graphics acceleration to their virtual machines under Linux with their "SVGA" graphics adapter backed by a mainline, open-source driver stack. That's worked out well and is now being extended for VMware's forthcoming third iteration of SVGA. 

Ampere Hardware & Kali Linux

Filed under

When Ampere partnered with Debian, this caught our eye. We were aware that our current ARM cloud provider was soon ending support for arm64 servers (which we use for our build daemons).

At Kali Linux, one of the things which is important to us, is that we prefer not having to cross-compile our ARM binaries that we ship in our Kali packages.


We reached out to Ampere to see if they would be able to help us out. We soon realised they have the same mindset as we do, ARM is the way forward. When developing Kali Linux, we treat ARM devices as “first class citizens”, just like we do with our “desktop” images (amd64/i386). There are many advantages to ARM, such as using less power (which means they don’t need cooling), lighter (handy when traveling to be on site or mailing devices to be a drop box) and cheaper devices (client doesn’t have to return the device!). These make really small form factor devices - which for doing penetration testing or red team exercises on site, expands the possibilities of where to hide various devices (imagination is the only limitation). This is why we try and give the same user experience regardless of the platform you are using Kali on. This is why we have pre-generated images and build scripts for as many different devices as possible

System76 is about to re-define the Linux desktop experience with COSMIC

Filed under

It should come as no surprise that System76, the company always finding new ground in the intersection of open source software and OEM hardware, has embarked upon refining and retooling the Pop!_OS Linux desktop experience.

COSMIC is System76's way of taking the GNOME desktop environment and tweaking it to better suit the user experience, as defined by their user base. The company polled Pop!_OS users to find out how they work with the desktop. The results of that survey helped guide the company in developing COSMIC.

What is COSMIC? Simply put, it's a honed user experience for the GNOME desktop. From what I've seen, it looks to be superior in just about every way.

  • Detecting memory management bugs with GCC 11, Part 2: Deallocation functions

    The first half of this article described dynamic memory allocation in C and C++, along with some of the new GNU Compiler Collection (GCC) 11 features that help you detect errors in dynamic allocation. This second half completes the tour of GCC 11 features in this area and explains where the detection mechanism might report false positives or false negatives.

    Throughout this article, I include links to the code examples on Compiler Explorer for those who would like to experiment. You will find the links above the source code of each example.

  • Memory error checking in C and C++: Comparing Sanitizers and Valgrind

    This article compares two tools, Sanitizers and Valgrind, that find memory bugs in programs written in memory-unsafe languages. These two tools work in very different ways. Therefore, while Sanitizers (developed by Google engineers) presents several advantages over Valgrind, each has strengths and weaknesses. Note that the Sanitizers project has a plural name because the suite consists of several tools, which we will explore in this article.

    Memory-checking tools are for memory-unsafe languages such as C and C++, not for Java, Python, and similar memory-safe languages. In memory-unsafe languages, it is easy to mistakenly write past the end of a memory buffer or read memory after it has been freed. Programs containing such bugs might run flawlessly most of the time and crash only very rarely. Catching these bugs is difficult, which is why we need tools for that purpose.

    Valgrind imposes a much higher slowdown on programs than Sanitizers. A program running under Valgrind could run 20 to 50 times slower than in regular production. This can be a showstopper for CPU-intensive programs. The slowdown for Sanitizers is generally 2 to 4 times worse than regular production. Instead of Valgrind, you can specify the use of Sanitizers during compilation.

  • Building resilient event-driven architectures with Apache Kafka

    Even though cloud-native computing has been around for some time—the Cloud Native Computing Foundation was started in 2015; an eon in computer time—not every developer has experienced the, uh, “joy” of dealing with distributed systems. The old patterns of thinking and architecting systems have given way to new ideas and new problems. For example, it’s not always possible (or advisable) to connect to a database and run transactions. Databases themselves are giving way to events and Command Query Responsibility Segregation (CQRS) and eventual consistency. Two-phase commits are being replaced with queues and database sagas, while monoliths are replaced with microservices, containers, and Kubernetes. “Small and local” thinking rules the day.

    Now combine this with the fallacies of distributed processing, and suddenly event-driven architecture becomes very attractive. Thankfully, there are tools to make this possible. Apache Kafka is one of those tools.

    Kafka makes event processing possible; Red Hat OpenShift Streams for Apache Kafka makes event processing easy.

  • Kubernetes configuration patterns, Part 2: Patterns for Kubernetes controllers - Red Hat Developer

    This article is the second in a two-part article series on Kubernetes configuration patterns, which you can use to configure your Kubernetes applications and controllers. The first article introduced patterns and antipatterns that use only Kubernetes primitives. Those simple patterns are applicable to any application. This second article describes more advanced patterns that require coding against the Kubernetes API, which is what a Kubernetes controller should use.

    The patterns you will learn in this article are suitable for scenarios where the basic Kubernetes features are not enough. These patterns will help you when you can’t mount a ConfigMap from another namespace into a Pod, can’t reload the configuration without killing the Pod, and so on.

    As in the first article, for simplicity, I’ve used only Deployments in the example YAML files. However, the examples should work with other PodSpecables (anything that describes a PodSpec) such as DaemonSets and ReplicaSets. I have also omitted fields like image, imagePullPolicy, and others in the example Deployment YAML.

  • Hybrid work model: Qualcomm IT, HR execs share 6 priorities for leaders

    Traditionally, the workplace has been where employees have developed a sense of belonging. In addition to getting lots of work done, it’s where we’d connect with others while walking to a meeting, share hopes and hardships over a cup of coffee, and set and achieve career goals and aspirations. As we all know, COVID-19 has forever changed that.

    We’re now in a unique position to reimagine work through new technologies and by reframing the employee experience to imagine something even better than before. At Qualcomm, human resources and IT have partnered to spearhead the future of work. This partnership has provided us with a unique, well-rounded perspective on how we work with our employees, what we need to support them, and has helped us envision what the dynamics of hybrid work will look like in the years ahead.

  • Qt Creator 4.15 released

    We added a locator filter for opening files from anywhere on your disk. This locator filter was already available on macOS using Spotlight. Now it also is available on Linux and Windows, and can be configured to use any external command line tool that returns a list of files. The default setting is using "locate" on Linux and "everything" on Windows.

    Sometimes it is difficult to configure the environment variables that are set when Qt Creator is run, which in turn affects external tools run from Qt Creator. We added a global option for this in Tools > Options > Environment > System > Environment. This adapts the system environment which is then further modified by the kit environment, the build environment, and the run environment.

  • Qt Creator 4.15 Released For This Qt/C++ IDE

    Qt Creator 4.15 isn't the most exciting feature release but does have some minor improvements in tow. Qt Creator 4.15 adds a locator filter, a user interface for setting environment variables that should be set automatically when running this IDE, a wide variety of C++ support improvements, continued improvements to its Language Server Protocol (LSP), debugging enhancements, and also a option for running applications as root from Qt Creator.

  • How To Install Apache Nifi on Ubuntu 20.04 LTS - idroot

    In this tutorial, we will show you how to install Apache Nifi on Ubuntu 20.04 LTS. For those of you who didn’t know, Apache NIFI is an open-source scalable tool to manage transformation, data routing, and system mediation logic. To put it in layman’s terms nifi simply automates the flow of data between two or more systems. Apache NiFi supports powerful and scalable directed graphs of data routing, transformation, and system mediation logic.

    This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of the Apache Nifi on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.

  • How to best set up command aliases on Linux

    Used frequently, bash aliases can make working on the Linux command line a lot smoother and easier, but they can also be complicated and hard to remember. This post examines how you might make your aliases work for you rather than vice versa.


    One of the nice things about aliases is that they remain available as you move around in your file system. They don't depend on your location or what's in your PATH variable. If you end up with 65 aliases, you might need to check them from time to time just to remember what they do. However, if you have to check very often, they might not be serving you as well as they should.

  • How to configure Noscript for ordinary users

    The Noscript Security Suite (NSS) is a fantastic, fantastic tool. It comes as an extension for Firefox and various Chromium-based browsers, and what it does is transform the useless, noisy so-called "modern" Internet into a pool of tranquility. And it does so by blocking scripts and other elements on Web pages. Beautiful, elegant. You end up with a fast, quiet experience. No nagging, no overhead. When you do need scripting, you selectively enable it. Works great, but only if you're a techie.

    Unfortunately, for common folks AKA not nerds, this is not a solution. They can't be bothered with per-site permissions, figuring out if something is broken when scripts don't run, or similar. But then, what if you do want to have all the flexibility of non-restricted browsing but still use some of the great powers of Noscript? Well, I think I may have the formula. Follow me.

  • How to accurately match OVAL security data to installed RPMs

FreeBSD's Q1 Report

This report covers FreeBSD related projects for the period between January and March, and is the first of four planned reports for 2021. The first quarter of 2021 has been very active in both FreeBSD-CURRENT and -STABLE, with 13.0-RELEASE work starting in January and finishing up mid-April.

The number of entries is slightly down, and this is probably due to a combination of factors like code slush as well as the ongoing issues with COVID-19, but we naturally hope that things will look up next quarter. This combined with a switch-over to AsciiDoctor and a decision to make full use of the status report work schedule to avoid stress, means that the report can now be expected to come out at the end of the first month after the quarter has finished, rather than in the middle. This report in particular includes a number of interesting entries, covering everything from the linuxulator, various mitigation work, long-awaited work on OpenBSM, work on kernel sanitizers, and many more things that it is hoped you will enjoy reading about. Yours, Daniel Ebdrup Jensen, with a status hat on. Read more Also: FreeBSD Is Off To A Good 2021 Start With FreeBSD 13.0, PIE By Default, helloSystem

  • The snap developer’s guide on how to migrate to new bases | Ubuntu

    A couple of weeks ago, we published an article about Ubuntu 16.04 entering Extended Security Maintenance (ESM), and the implications of this change for snap publishers. We talked about the different options available to developers and publishers who still may rely on the older bases in their build process – free Ubuntu Advantage (UA) tokens, Launchpad and Snapcraft Build Service, snapcraft support for ESM base, and others. However, for the majority of publishers, migrating away from the ESM base (core) to core18 and core20 offers the highest degree of flexibility.
