  • Solene runs BSD

    As an OpenBSD developer, I have been mostly working on ports at first, then I have learned about how man page are written. This made me contribute to OpenBSD documentation and I really enjoy it. I’ve been quite active on OpenBSD IRC channel, I’ve seen people being clueless due to missing explanations here and there, so I’ve did my best to enhance documentation to make it easier to understand to everyone. Lately, I’ve resurrected stable binary packages (which disappeared around OpenBSD 4.x I think) and I am very happy about this.

  • The Early History of Usenet, Part IV: Implementation and User Experience

    To understand some of our implementation choices, it's important to remember two things. First, the computers of that era were slow. The Unix machine at UNC's CS department was slower than most timesharing machines even for 1979 — we had a small, slow disk, a slow CPU, and — most critically — not nearly enough RAM. Duke CS had a faster computer — they had an 11/70; we had an 11/45 — but since I was doing the first implementation, I had to use what UNC had. (Log in remotely? How? There was no Internet then, neither department was on the ARPANET, and dialing up would have meant paying per-minute telephone charges, probably at daytime rates. Besides, a dial-up connection would have been at 300 bps, but if I stayed local, I could do 9600 bps via the local Gandalf port selector.)

    The second important point is that we knew we had to experiment to get things right. To quote from the first public announcement of Usenet, "Yes, there are problems. Several amateurs collaborated on this plan. But let's get started now. Once the net is in place, we can start a committee. And they will actually use the net, so they will know what the real problems are." None of us had designed a network protocol before; we knew that we'd have to experiment to get things even approximately right. (To be clear, we were not first-time programmers. We were all experienced system administrators, and while I don't know just how much experience Tom and Jim (and Dennis Rockwell, whose name I've inadvertently omitted in earlier posts) had, I'd been programming for about 14 years by this time, with much of my work at kernel level and with a fair amount of communications software experience.)

  • North Carolina aims to bring more women into computer science

    It's well-known that women are under-represented in computer science and technology. A new initiative led by the NC Department of Public Instruction, Duke University, and IBM is working to reverse that trend by using an open source approach to bringing more computer science instruction into NC public schools.

    "If we are going to truly shatter the outdated and unfortunately often dehumanizing system of education that we know today, we have got to use an open source approach to do it," says Duke University professor Aria Chernik, who co-presented the Lightning Talk with Mary Hemphill of the NC Department of Public Instruction.

    Watch "#IAmCS: An open source approach for equity-focused computer science education," their Lightning Talk at the seventh annual All Things Open conference, to learn more about the #IAmCS campaign that aims to enroll more female students in computer science classes and encourage them to pursue careers in the field.

  • Here’s One Reason the U.S. Military Can’t Fix Its Own Equipment

    At the time, I hadn’t heard of “right-to-repair” and didn’t know that a civilian concept could affect my job in the military. The idea behind right-to-repair is that you (or a third-party you choose) should be able to repair something you own, instead of being forced to rely on the company that originally sold it. This could involve not repairing something (like an iPhone) because doing so would void a warranty; repairs which require specialized tools, diagnostic equipment, data or schematics not reasonably available to consumers; or products that are deliberately designed to prevent an end user from fixing them.

  • 110 Nursing Homes Cut Off from Health Records in Ransomware Attack

                         

                           

    At around 1:30 a.m. CT on Nov. 17, unknown attackers launched a ransomware strain known as Ryuk inside VCPI’s networks, encrypting all data the company hosts for its clients and demanding a whopping $14 million ransom in exchange for a digital key needed to unlock access to the files. Ryuk has made a name for itself targeting businesses that supply services to other companies — particularly cloud-data firms — with the ransom demands set according to the victim’s perceived ability to pay.

                           

    In an interview with KrebsOnSecurity today, VCPI chief executive and owner Karen Christianson said the attack had affected virtually all of their core offerings, including Internet service and email, access to patient records, client billing and phone systems, and even VCPI’s own payroll operations that serve nearly 150 company employees.

  • Apple pulls all customer reviews from online Apple Store

                         

                           

    AppleInsider received a tip from a reader who had noted the buyer review section was missing on Apple's online retail store page. The user also pointed out that the pages have been removed from U.S., U.K., and Australian Apple online stores, which suggests this is not simply a mistake, but rather an intentional move on Apple's behalf.

                           

    The reviews were pulled over the weekend, though it's not clear as to why this has happened. Apple had been known for leaving up even especially negative reviews, which demonstrated both transparency and integrity to their customers.

  • 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.
