  • How LinkedIn’s password sloppiness hurts us all

    Me: "The full dump from the 2012 LinkedIn breach just dropped, so you're probably not going to see much of me over the next week."

    Wife: "Again?"

    Yes, again. If you're just waking up from a coma you would be forgiven for thinking that it's still 2012. But no, it's 2016 and the LinkedIn breach is back from the dead—on its four-year anniversary, no less. If you had a LinkedIn account in 2012, there's a 98 percent chance your password has been cracked.

    Back in 2012, fellow professional password cracker d3ad0ne (who regretfully passed away in 2013) and I made short work out of the first LinkedIn password dump, cracking more than 90 percent of the 6.4 million password hashes in just under one week. Following that effort, I did a short write-up ironically titled The Final Word on the LinkedIn Leak.

  • The Internet of Things

    A common question is whether or not IoT is something new and revolutionary or a buzzword for old ideas? The answer is “yes”…

    Much of the foundation of IoT has been around for quite a while. SCADA systems, or Supervisory Control And Data Acquisition has been around since the 1950’s managing electrical power grids, railroads, and factories. Machine communications over telephone lines and microwave links has been around since the 1960’s. Machine control systems, starting on mainframes and minicomputers, have also been around since the 1960’s.

    The big changes are economics, software, and integration. Microsensors and SoC (System on a Chip) technology for CPUs and networking are driving the cost of devices down – in some cases by a factor of a thousand! Advances in networking – both networking technology as well as the availability of pervasive networking – are changing the ground rules and economics for machine to machine communication.

  • Signal and Google Cloud Services

    I just installed Signal on my Android phone.

    It wasn't an easy decision. I have been running Cyanogenmod, a Google-free version of Android, and installing apps from F-Droid, a repository of free software android apps, for several years now. This setup allows me to run all the applications I need without Google accessing any of my cell phone data. It has been a remarkably successful experiment leaving me with all the phone software I need. And it's consistent with my belief that Google's size, reach and goals are a menace to the left's ability to develop the autonomous communications systems on the Internet that we need to achieve any meaningful political change.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. 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 the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
