      • Linux LinksBest Free and Open Source Alternatives to Google Sheets

        Google has a firm grip on the desktop. Their products and services are ubiquitous. Don’t get us wrong, we’re long-standing admirers of many of Google’s products and services. They are often high quality, easy to use, and ‘free’, but there can be downsides of over-reliance on a specific company. For example, there are concerns about their privacy policies, business practices, and an almost insatiable desire to control all of our data, all of the time.

        What if you are looking to move away from Google and embark on a new world of online freedom, where you are not constantly tracked, monetised and attached to Google’s ecosystem.

        In this series we explore how you can migrate from Google without missing out on anything. We recommend open source solutions.

      • ByteXDHow to Use Fasd in Linux for Quick Access to Files & Directories

        Linux users often rely on the command line, but tedious and time-consuming tasks can make it frustrating. Navigating and moving between directories using cd and ls commands, plus typing long path files to access, copy or list files, can be annoying for even advanced users.

        To solve the problem of directory navigation and accessing files from other locations in the system using command lines, the fasd tool has been created exactly for this purpose. fasd is a command line utility written in Shell that serves as an advanced version of the autojump and z command utilities; we can call also: Autojump plus z with support for files.

        This Linux tool allows the user to quick access a previously visited directories and files from any location in the system.

        Fasd can be described as a faster solution to navigate and access the user’s frequent and recent directories and files. This helpful utility saves the frequently visited directories and files (i.e. History) from the command line into a database in order to render filesystem navigation possible and quite easy just by typing small patterns.

        In this article you will learn how to use fasd to easily access files and directories without specifying their full path or executing numerous cd commands.

        So… yes, there is a clear downwards trend towards the last few years. And it does make sense, all in all: Not only have I managed to keep myself busier than before, but… Blogging is a social endeavor. And as people have moved over to the different flavors of social networks, there is somewhat less fueling us to share our thoughts and experiences in this fashion.

        So this connects me to my first point: Staring at Noodles’ Emptiness, I got to a campaign to Bring Back Blogging. I stand by all of what they suggest: Blogs are a great invention, they allow the sharing of a great insight into a person’s mind, ideas and worldview (and even more so if, like mine, it shows already a window of almost two decades of life! This year my blog will be old enough to vote!), they are completely decentralized, and can be easily grouped according to each readers’ preferences via the RSS format.

        As we tend to mention often, cameras are one of the areas where Linux phones are often seen as lacking behind their Android alternatives. This is partly due to extreme fragmentation of sensor drivers, with most mainlined devices not having any kind of Linux camera support, and just partly due to the lack of a software infrastructure for acquisition and post-processing.

        The first camera app for Linux phones was Megapixels, developed by Martijn Braam as a Python GTK3 app for the PinePhone, and now the standard choice for Linux mobiles. Megapixels can be easily extended to new phones with a working kernel camera driver through configuration files, which specify sensor drivers to use, colour processing matrices, how previews are to be displayed, and much more.

        Electronics engineering student Vlad Tomoiagă has come up with a neat way to experiment with field-programmable gate array (FPGA) concepts without having to splash out on an actual FPGA — by simulating one on a Raspberry Pi Pico or other RP2040-based microcontroller board.

        "This project aims to simulate Verilog HDL [Hardware Description Language] designs on a Raspberry Pi Pico (or any other RP2040-based board)," Tomoiagă explains of FakePGA. "It achieves this by using Verilator to compile the RTL [Register Transfer Level code] into a cycle-accurate C++ model of your design which can then be executed on the microcontroller. This allows you to access the signals of the simulated design through the GPIO [General-Purpose Input/Output] pins of the board, which gives a more hands-on experience than simulating on a computer."

      • Linux HintStd List C++

        In C++, std::list is like a container that stores the elements on the non-contagious memory location. The “std::list” is implemented as a doubly linked list. We can insert or remove any element of the list that is stored in any location, which makes the lists bidirectional and sequential. Bidirectional because we can access the list elements from the front and back of the list (from any location). Sequential because we can access the elements anywhere in the sequence. Lists behave as doubly linked lists. Doubly linked lists can store their elements anywhere in the memory and they can be accessed from any location on the runtime. The list belongs to a standard template library like arrays and vectors but lists do not allow a fast access comparable to other data structures. Let’s discuss “std::list” in this article with the practical implementation of lists with different operations.

      • Can we encrypt data using Elliptic Curves? - Andrea Corbellini

        From time to time, I hear people saying that Elliptic Curve Cryptography (ECC) cannot be used to directly encrypt data, and you can only do key agreement and digital signatures with it. This is a common misconception, but it's not actually true: you can indeed use elliptic curve keys to encrypt arbitrary data. And I'm not talking about hybrid-encryption schemes (like ECIES or HPKE): I'm talking about pure elliptic curve encryption, and I'm going to show an example of it in this article. It's true however that pure elliptic curve encryption is not widely used or standardized because, as I will explain at the end of the article, key agreement is more convenient for most applications.

        [...]

        I wrote an in-depth article about elliptic curve cryptography in the past on this blog, and here is a quick recap: points on an elliptic curve from an interesting algebraic structure: a cyclic group. This group lets us do some algebra with the points of the elliptic curve: if we have two points $A$ and $B$, we can add them ($A + B$) or subtract them ($A - B$). We can also multiply a point by an integer, which is the same as doing repeated addition ($n A$ = $A + A + \cdots + A$, $n$ times).

        We know some efficient algorithms for doing multiplication, but the reverse of multiplication is believed to be a "hard" problem for certain elliptic curves, in the sense that we know efficient methods for computing $B = n A$ given $n$ and $A$, but we do not know very efficient methods to figure out $n$ given $A$ and $B$. This problem of reversing a multiplication is known as Elliptic Curve Discrete Logarithm Problem (ECDLP).

        Conversations about reducing these emissions typically focus on electric vehicles. But increasingly, government officials across the country are aiming not just to get Americans into different kinds of cars, but to radically reduce the need to drive in the first place.

      • as days pass by - What to do about€ hotlinking

        Hotlinking, in the context I want to discuss here, is the act of using a resource on your website by linking to it on someone else’s website. This might be any resource: a script, an image, anything that is referenced by URL.

        It’s a bit of an anti-social practice, to be honest. Essentially, you’re offloading the responsibility for the bandwidth of serving that resource to someone else, but it’s your site and your users who get the benefit of that. That’s not all that nice.

        Now, if the “other person’s website” is a CDN — that is, a site deliberately set up in order to serve resources to someone else — then that’s different. There are many CDNs, and using resources served from them is not a bad thing. That’s not what I’m talking about. But if you’re including something direct from someone else’s not-a-CDN site, then… what, if anything, should the owner of that site do about it?

      • Wladimir PalantSouth Korea’s online security dead end | Almost Secure

        Last September I started investigating a South Korean application with unusually high user numbers. It took me a while to even figure out what it really did, there being close to zero documentation. I eventually realized that the application is riddled with security issues and, despite being advertised as a security application, makes the issue it is supposed to address far, far worse.

        That’s how my journey to the South Korea’s very special security application landscape started. Since then I investigated several other applications and realized that the first one wasn’t an outlier. All of them caused severe security and privacy issues. Yet they were also installed on almost every computer in South Korea, being a prerequisite for using online banking or government websites in the country.

        [...]

        Originally, these applications used Microsoft’s proprietary ActiveX technology. This only worked in Internet Explorer and severely hindered adoption of other browsers in South Korea.

      • Finding and Fixing DOM-based XSS with Static Analysis

        Despite all the efforts of fixing Cross-Site Scripting (XSS) on the web, it continuously ranks as one of the most dangerous security issues in software.

        In particular, DOM-based XSS is gaining increasing relevance: DOM-based XSS is a form of XSS where the vulnerability resides completely in the client-side code (e.g., in JavaScript). Indeed, more and more web applications implement all of their UI code using frontend web technologies: Single Page Applications (SPAs) are more prone to this vulnerability, mainly because they are more JavaScript-heavy than other web applications. An XSS in Electron applications, however, has the potential to cause even more danger due to the system-level APIs available in the Electron framework (e.g., reading local files and executing programs).

        As I try to get myself back into something that resembles a routine after the holiday break I started to poke around at some things that have been needing attention. It seems that my microblog to gemini renderer has been broken for about a month. A quick fix and it seems to be functioning but that gave me an excuse to tweak the overall layout. Previously I rendered gemtext headings for the years and the months, leaving the individual entries as just simple paragraphs, however it seems more logical to expose individual entries so you can navigate the in-reply-to chain using your user-agent, assuming it has the ability to navigate headings (Lagrange does).

      • PocketBook Basic 4 review

        I read lots of books, so I bought an e-reader for myself, the PocketBook Basic 4, also known as the PocketBook 606 in some regions. It was one of the cheapest options available, while not selling your data to Amazon or Kobo. This is a review after 2 months of usage.

        It has no touch screen, being navigable using a 4-way touch pad. That was one of the selling points for me, as I didn't want this to be a glorified phone, and besides, less screen wiping. It's made out of plastic, which makes it really light at around 140g, perfect for carrying around. The e-ink display is HD, perfect for reading any sorts of books. It supports all popular e-book formats and PDFs. Best of all, it runs Linux! More specifically, the kernel version is 3.0, I don't think the interface is FOSS though. It doesn't connect to the Internet whatsoever, which is a huge plus for me, it helps you stay disconnected. The battery is rated at around one month, although personally at my reading-rate, I see it lasts around 2 weeks. If you put an SD card in, then plug it into a computer, it'll act as an SD card reader which is really awesome! For example, on Linux it adds two new devices, the internal memory which is 8GB, and the SD card. This way you don't need a converter in order to load your favorite books.

        • internet nostalgia - an incoherent rambling about how new internet culture sucks

          ay mates, lelkins here. this might be a pretty short post. i keep remembering memes that used to be the biggest things on the internet. like current ones that just fizzled out fast like ronaldinho soccer 64, megalovania (this one is still kind of popular), so many examples that i can't put them in (and cause i actually forgot most of them. reason why later). and more common in my head are ones that i used to see as a kid from the era of "fads", like hotel mario edits where every noun is replaced with a random clip, "the king has a new computer", one youtube poop where mario and luigi fight eachother in a pokemon battle and mario charges a pinesol bottle and luigi just uses za warudo from jojo. the internet was wild and quality always differed.

        • emerging from darkness

          With the release of version 4 of Mastodon [1] there has been a problem of links to profile pages or conversation threads "going dark" within shell based browsers, such as Lynx [2]. In version 3.x you would get a text rendering of each page, but now you only get a terse *"To use the Mastodon web application, please enable JavaScript"* message.

          I had been following the philosophy of *"do the minimum thing that works"* with Epicyon [3], but after Mastodon 4, just linking directly to Mastodon web content was no longer sufficient to be universally legible. So I have now replaced those direct links with a *conversation view* and a different way of viewing Mastodon profiles in which the html is all rendered by Epicyon itself. This brings back the otherwise Javascript-shrouded fediverse content, and also has the added advantage that it fully supports *authorized fetch*, which in Mastodon is known as "secure mode". It also makes the user interface more consistent looking in shell browsers.

        • Gemlog responses - bacardi55's concept without CGI

          Gemlog discussions are frequently happening, which is a good sign for an active community. Due to the simplistic nature of the gemini protocol these discussions happen with much less automation and more handwork than in the world wide web. The usual way is to publish a reply with the link to the original gemlog and inform the original author via email about the reply.

        • [Old] re: "I kind of resent blogs" by adiabatic

          is it? there isn't really a built-in mechanism through which you would be made aware whether your work is being noticed or not, and that's by design. I don't know how common this is, but I don't find it to require much effort to keep up with everything that shows up on the main CAPCOM/spacewalk instances so I keep up with it regularly.

          there wasn't any contact information anywhere in your gemini capsule, so I can't reach out and tell you that I've responded to your post, so I guess we'll see if you notice this. this gemlog doesn't have a feed of any kind, so if you see it, I guess content *can* be noticed without an atom feed.
