There are three main ways to install Node.js: using pre-compiled binaries, a version manager like NVM, or compiling from source. Pre-compiled binaries are easy to install but require reinstallation for updates or version changes. NVM allows quickly installing and switching between versions from the command line but requires installing the manager first. Compiling from source gives the latest code but is more complex. The author recommends using a version manager like NVM for flexibility in switching versions without reinstalling.

Create the first Juniper vMX router using GNS3 VM & VMware Fusion
MX routers are Juniper's main routers that can be used as edge routers or core routers. They are feature-rich and cost-effective. To use a vMX router in GNS3, you first need to install GNS3 and download the necessary vMX image files. Then you can manually create a template for the vMX that specifies configuration details like the Junos version. Finally, you instantiate a vMX router instance using the template, which may take some time to load. A vMX router consists of a virtual control plane (vCP) and forwarding plane (vFP) connected by internal and management interfaces.

It describes extending the bsdinstall script to allow device preparation, installation, and configuration to be automated. Key parameters that can be configured include partitions, ZFS settings, package mirrors, and post-install configuration like hostname, users, and network configuration. The FAI allows unattended FreeBSD installations from a network boot using PXE or iPXE without requiring an NFS server. A demo is provided of a local mirror with DHCP and TFTP servers to netboot multiple clients for automated installation via the FAI.
D-RTM for Qubes OS VMs
Dynamic Root of Trust for Measurement is a Trusted Computing technique to establish or reestablish trust without a reboot. In this presentation, the author discusses the use of D-RTM, especially its open-source implementation called TrenchBoot, for a virtual machine environment based on Xen hypervisor.
Qubes OS and TPM 2.0
The document discusses adding support for TPM 2.0 chips in Qubes OS. Currently, Qubes only supports TPM 1.2 chips and cannot detect TPM 2.0 chips. The Linux kernels used in Qubes (4.14 and 4.19) are missing some TPM 2.0 configuration options. Testing on real hardware with a TPM 2.0 chip showed the chip is detected but Qubes reports "Device not found". Integrating TPM 2.0 support would allow using newer TPM standard chips but may require changes to tools like Anti-Evil Maid that currently only support TPM 1.2.
Getting started with docker
To get started with Docker, install the Docker Desktop application and make a Docker ID. For Java deployments, package code into a JAR/WAR/EAR file that can run on the host JVM. With Docker, applications are packaged into images that follow a standard format and are run by the Docker engine instead of a full virtual machine and guest OS, reducing memory usage. Docker releases new major versions quarterly and each is supported for one year.

Vagrant + Ansible + Docker
This document discusses using Vagrant, Ansible, and Docker together to build portable infrastructure that avoids dependency issues, allows consistent workflows, and reduces risk. Vagrant is used to create and manage virtual environments from a configuration file. Ansible then provides configuration management through push-based execution of tasks without a client. Docker adds portability by allowing applications to run in lightweight isolated containers across machines. A sample project demonstrates Vagrant starting a VM, Ansible provisioning it by starting a Docker container, and an application running within the container.
Virtualization for Developers
The rise of virtualization has transformed the server business, but other than that it seems like the developer world has largely been left behind. Regardless of if you are working on one project, or have 20 clients, every developer should know how to use virtualization to create seamless and easy to manage development environments. In this talk we will take a practical approach to using a combination of Puppet, Vagrant, and VirtualBox to create entire development environments in a matter of moments - and even better re-use that template for any project you have in the future in a version-controlled and easily managed manner. Bringing on a new developer for your project? We'll show you how they can get a full-fledged development environment from zero to working in under 10 minutes.

Motivation copy
Motivation is what causes an individual to move towards a goal. Abraham Maslow's hierarchy of needs explains that individuals are motivated to fulfill basic physiological needs like hunger and thirst before progressing to higher level needs. Self-motivation involves breaking large tasks into small steps and taking action without waiting for inspiration. Effective motivational strategies include finding new skills, getting feedback, expanding abilities, and rotating work assignments. Goal setting is important for motivation, with goals needing to be specific, measurable, attainable, relevant, and time-oriented. Short-term goals can be achieved quickly while long-term goals take more time to accomplish.

Infrastructure = Code
Infrastructure as code is an approach to managing servers where their configuration is defined using code and version control rather than manual shell commands. Ansible is a tool that allows defining servers' desired state in YAML files checked into version control. It can automatically install software, configure systems, and ensure consistency across multiple servers using SSH without requiring an agent. Playbooks declare tasks to run that are idempotent, allowing Ansible to safely deploy changes. This approach improves on manual configuration by enabling testing, collaboration, and rolling back changes if needed.
Building your own Desktop Cloud Environment
As developers we have seen these problems:
Our development environments accumulate lots of applications and libraries over a period of months.
We are usually in the habit of installing everything in one machine.
We fear that we may screw up our development environment and that means unproductive man-hours.
We forget that a multi-machine deployment is different from a single machine deployment.
How about virtualization in the desktop?

Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application.
I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.
zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

“Temporal Event Neural Networks: A More Efficient Alternative to the Transfor...Edge AI and Vision Alliance
For the full video of this presentation, please visit: https://www.edge-ai-vision.com/2024/06/temporal-event-neural-networks-a-more-efficient-alternative-to-the-transformer-a-presentation-from-brainchip/
Chris Jones, Director of Product Management at BrainChip , presents the “Temporal Event Neural Networks: A More Efficient Alternative to the Transformer” tutorial at the May 2024 Embedded Vision Summit.
The expansion of AI services necessitates enhanced computational capabilities on edge devices. Temporal Event Neural Networks (TENNs), developed by BrainChip, represent a novel and highly efficient state-space network. TENNs demonstrate exceptional proficiency in handling multi-dimensional streaming data, facilitating advancements in object detection, action recognition, speech enhancement and language model/sequence generation. Through the utilization of polynomial-based continuous convolutions, TENNs streamline models, expedite training processes and significantly diminish memory requirements, achieving notable reductions of up to 50x in parameters and 5,000x in energy consumption compared to prevailing methodologies like transformers.
Integration with BrainChip’s Akida neuromorphic hardware IP further enhances TENNs’ capabilities, enabling the realization of highly capable, portable and passively cooled edge devices. This presentation delves into the technical innovations underlying TENNs, presents real-world benchmarks, and elucidates how this cutting-edge approach is positioned to revolutionize edge AI across diverse applications.Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
