Secure Shell Protocol (SSH) is a cryptographic network protocol for operating network services securely over an unsecured network. Notably used for remote logins and command-line execution. SSH protects the privacy and integrity of the transferred data or files over a network. It helps block sniffing attacks on the network. In this tutorial, I will show you how to install and enable the SSH server on fedora 35.
Before we can install the SSH server, we first need to understand how this server works. It mostly works on the client/server model. The SSH client initiates the setup of a secure connection and the SSH server listens to the incoming connection on TCP port 22 and makes a response. The server then authenticates itself to the client by providing the public key. This allows the client to know it is communicating with the correct server.
When you are running a couple of containers, it’s okay to stop or remove containers one by one, but it’s not feasible when you are running multiple microservice containers.
In my instance, I have a bunch of microservices that get deployed and stacked together. In total, I have more than 25+ service containers running and now I want to stop them. What command should I run to stop or remove all Docker containers at once?
It’s not a big deal; you can remove or stop containers at once by running a single command, which is the confluence of multiple commands.
Nomacs is an open-source, free image viewer that supports multiple platforms. You can use it for viewing all standard formats, including RAW and PSD files, by tapping on the widget with additional information such as thumbnails or histograms revealed beneath its semi-transparent surface – no need to open up another app!
The imaging software also contains many features, such as it can be used to adjust the brightness, contrast, and hue of an image while maintaining saturation. It also has a pseudo color function that allows you to create false colors studies in one go with ease! Another unique feature about nomac’s software is its ability for multiple instances where it will sync up any changes made from different zoom levels or panning motions, so they match perfectly on screen at all times – making review sessions much more informative than before as well because viewers can see exactly how things changed when zooming around inside each photo frame.
uGet is a lightweight download manager perfect for those who want to speed up their downloads without installing a bloated program. It’s also open-source, which means the code is available for anyone who wants to take a look and make modifications as they see fit.

Wget command is a command-line tool that downloads files over the internet to your Linux system. It accepts multiple options which alter the nature of the file download such as saving a file with a different name, downloading a file to a specified location on the Linux system other than the present working directory, limiting the bandwidth and so much more.
In our guide, we explore different wget command usage examples in Linux.
Being a Linux enthusiast only has pros. There are more than enough Linux operating systems to play around with or explore. Linux server administration and management skills are important for the configuration of your Linux operating system internals like files, services, disk quotas, and users.
However, one can only get so far with Linux server administration and management due to the need to master and execute Linux command sequences set to meet certain objectives.
Web admin creates a compartmentalization experience as you explore Linux server management and administration. You do not need to walk around with Linux OS commands manually to check the status of your Linux server machines.
Wine is an incredible tool that can help you install Windows apps on Linux, but how exactly can you install it on your Linux PC? In this article, we’ll be looking at installing Wine on all Linux distributions.
For those who don’t know how Wine works or what it means, Wine stands for “Wine is not an emulator” (Yep, Linux nerds love recursions), and it’s a program that uses the Windows API along with other libraries to install and run Windows apps (.exe files) on Linux.

MongoDB is one of the more popular NoSQL databases on the market (with over 50% of the market share). This database is a great option for enterprise businesses or any company looking to leverage massive data sets.
For most of today's developers, using Git is akin to breathing, in that you can't live without it. Along with version control, Git's use has even expanded in recent years into the area of GitOps, or managing and versioning configurations through Git. What a lot of users don't realize or think about is that Git tracks not only file changes for each commit but also a lot of meta-data around commits and branches. Your DevOps can leverage this data or automate IT operations using software development best practices, such as with CI/CD.
Was EmuDeck not to your liking? Perhaps RetroDECK might be what you're after for retro emulation on the Steam Deck.
Unlike EmuDeck that has you install multiple things in a list, and have them all separated, the idea of RetroDECK is more to bring a "one-click experience, and to separate retrogames from steam library" the developer says. It comes as a Flatpak to install, and from there it should have everything bundled together. Inspired by the likes of 351ELEC (what it's forked from), EmuELEC, CoreELEC, Lakka, and Batocera.
Love your pixel-art side-scrolling action RPGs? Keep an eye on Meifumado, as it looks pretty good and it will be coming to Linux the developer has confirmed. It recently had a successful Kickstarter campaign, where Old Bit Studio raised $48,018 to bring out the full version.
You can now go on A Short Hike wherever you want with the Steam Deck and perhaps bring along a whole lot of friends too. More about it: Hike, climb, and soar through the peaceful mountainside landscapes of Hawk Peak Provincial Park. Follow the marked trails or explore the backcountry as you make your way to the summit. Along the way, meet other hikers, discover hidden treasures, and take in the world around you.
DDraceNetwork, a free and open source online co-op platformer now has Vulkan API integrated as of the latest update. Starting off life as a simple mod for Teeworlds, nowadays it's a popular standalone multiplayer platformer that can be quite the challenge.
Seems it's remaining somewhat popular too, especially with the Steam release, which sees over 2,000 players online at a time every day. Might not sound like a lot but it's more than the likes of some much more well-known indie and AAA titles, so it is pretty impressive.
Lila's Sky Ark from Monolith of Minds is a standalone prequel story to their previous game Resolutiion and it looks absolutely gorgeous.

Exploring the universe is the most common desire of the curious young generation. But that is just a dream, and pretty much difficult to make it true. However, most probably, that’s the reason space games are always so popular among the young generation. When you are exploring a world, you must need a big screen. So, you will love to enjoy those games on your PC. However, if you are a Linux user and want to enjoy some space games for Linux, stick to us till the end of this article.
Freedom of choice is a central plank of open source software. It should be the user who decides how their computer is configured. That’s very relevant when choosing and configuring a desktop environment. One of Linux’s best features is its modularity.
Extensibility relates to the ability to customize a desktop environment to an individual’s preferences and tastes. This flexibility is offered by themes, extensions, and applets. The principle provides for enhancements without impairing existing system functions.
I've installed Alpine on it and carried on with my day to day work. Mostly I program my own ERP system that I actually started build on this exact computer. Programming a TUI application works fine, however since I also try to sell the ERP system, there's also an web interface and that is horrible slow. Running a modern chrome browser is slow. It works and I can use most sites, including youtube however it's noticable slower and even a bit too slow to use.
For being such a young project, MassOS impressed me in a number of ways. The developer really understands the benefit of documentation. The steps for downloading, installing, and updating the system are all documented in detail, often with screenshots. The documentation is well organized and pleasantly to the point. In other words, we're told how to do things and spared the developer's philosophical views and marketing pitch.
MassOS is super fast, I'm not sure I've ever encountered a distribution running Xfce which performed this well. The distribution has managed to disable or avoid installing almost everything it doesn't need while including the basics most people will want. For me, at least, I was able to accomplish most tasks with the software included and a couple of Flatpaks. I suspect, were I to use MassOS longer, I'd eventually run into trouble when it came time to install more obscure development tools and command line items, but I could probably work around that by using a third-party package manager such as Nix.
Finally, I really like the dark, fairly minimal interface. I like Xfce as it walks a nice line between capable and customizable. I like its balance of performance and features. I like that MassOS includes a dark theme which seems consistent across the included utilities. The desktop felt almost immediately comfortable for me - a few conveniences were presented and then it got out of my way.
There are just two drawbacks I see to MassOS after a day of use. One is that it has a text installer. Which, for me, isn't really a problem, but it gives the distribution a legacy vibe that could scare off some people. Shifting to another installer, such as Calamares, would probably attract more users.
The second drawback is the lack of a built-in package manager. We may not need one for acquiring desktop software, but it would be nice to have a way to install small security updates. Getting the user to download and execute a script isn't an ideal way to provide new versions of software. At the minimum, I think the shell script for performing updates should be included by default.
However, this lack of package manager aside, MassOS is surprisingly mature for a young project. It's fast, it seemed to be stable, it worked well with my hardware, and it's practically documented. I really hope the developer keeps working on this as, with a few small changes, I'd feel very much at home with this distribution.
After a long break, we finally have up-to-date Gentoo stages for the MIPS architecture available for download again! The weekly builds cover at the moment for 32-bit mips2 and mips32, for 64-bit mips3 and mips64 in o32, n32, and n64 ABI - and all that for both big and little endian. Should be good as a start for just about every hardware out there.
Like I said earlier, this is a short review, more of a cautious sampling of what Slackware can do. I am thinking of perhaps trying it on a "real" laptop, complete with Nvidia graphics and whatnot, to see how it's going to cope with an existing, somewhat complex partition layout and proprietary drivers. After all, if you can't use your hardware, and installing software is a pain, then the rest doesn't matter.
I do like the spartan approach, but it's also not feasible for most people out there. Even if you can get through the installation, the day-to-day usage needs to be simple and elegant. I don't know how accessible Slackware is when it comes to more complex things. I am mulling that endeavor still, and it could be an interesting little exercise. Anyway, so far so good. Not bad, but definitely nerdy and true to its original mission.

F(x)tec is gradually gearing to mass-produce the Pro1-X, a smartphone that it and XDA Developers hoped to ship in March 2021. As we discussed last February, F(x)tec delayed Pro1-X shipments by six months to August, which has since slipped to April 2022. Unfortunately, it seems unlikely that F(x)tec will hit its revised deadline, either.
Instead, trial assembly of the Pro1-X has started in Shenzhen. While the company is light on details, it has shared two videos showing the Pro1-X being manufactured. Apparently, the F(x)tec team have spent the rest of this week ‘continuously monitoring the production process’ to determine any problems before the company begins mass production. F(x)tec has not stated from when it would mass-produce the Pro1-X, though. Presumably, it will only do so if its trial assembly period is successful.
Meanwhile, F(x)tec has certified the Pro1-X with the Federal Communications Commission (FCC) in the US. Unsurprisingly, the FCC’s documents do not provide any new details about the Pro1-X. However, they are another step in the right direction for F(x)tec and the Pro1-X, its massive delays notwithstanding.
To recap, the F(x)tec still relies on the Snapdragon 662, plus up to 8 GB of RAM and 256 GB of storage. Arguably, the smartphone’s biggest feature is its slide-out keyboard, which will be compatible with Android and Ubuntu Touch. F(x)tec will also sell replacement batteries and displays, unlike most Android OEMs.
As you may have noticed, Raspberry Pi boards may get hard to get and/or be sold at excessive prices by some resellers. Eben Upton explains the reasons behind the Raspberry Pi Shortage and provides some recommendations to work around the shortage and high prices.
Raspberry Pi Trading is still manufacturing around 500,000 Raspberry Pi boards or modules per month despite the global semiconductors shortage, and the issue they face is more of a demand shock than a supply shock with demand for Raspberry Pi products having increased sharply from the start of 2021 and remains unabated as the supply chain can not handle that extra demand at this time. That means distributors have backlogs in almost all products, and it takes time for customers to get their orders.
As a standard feature of the Linux kernel, device tree overlays (DTOs) allow for easy enabling and configuration of features and drivers, such as those contained within the standard firmware of a Raspberry Pi system. Using these DTOs it’s trivial to set up features like as a soft power-off button, triggering an external power supply and enable drivers for everything from an external real-time clock (RTC) to various displays, sensors and audio devices, all without modifying the operating system or using custom scripts.
It’s also possible to add your own DTOs to create a custom overlay that combines multiple DTO commands into a single one, or create a custom device tree binary (DTB) for the target hardware. Essentially this DTB is loaded by the Linux kernel on boot to let it know which devices are connected and their configuration settings, very similar to what the BIOS component with x86-based architectures handles automatically.

Sys.path is a list of directories where the Python interpreter searches for modules. Mind you, this is a list! When a module is claimed in a project file, it will search through each one of the directories in the list. If the module is located within one of those directories, then everything goes fine and your project is successfully rendered. However, if the module is not located within any of the listed directories, then your project will fail lest you can “append” the directory where your module is located to the list using the append() function. In this tutorial, we’ll be learning about how to use sys.path.append() in Python.
Redis is a free, open-source in-memory database widely adopted as a caching mechanism or message broker.
Although it is very versatile and extensive by default, it does allow you to extend functionality using its embedded Lua interpreter. This means that you can write scripts written in Lua to perform additional operations on your Redis database.
In Redis, partitioning refers to splitting data into multiple instances. This means that each Redis holds a section of your entire data set. It is a handy feature, especially when dealing with large datasets.
Let us look at various types of partitioning in Redis and the cost and benefits of each.
Streams are a simple but versatile and powerful data structure that allows you to implement streams in Redis. Streams are built-in types from Redis version 5.0 and can help remove the limitations of log data structure.
In this article, we will focus on using and working with Redis streams rather than the actual implementation. You can, however, check the docs for more.
Redis Pipelining refers to a feature that allows you to send multiple commands to the Redis server in one go. Instead of sending a command and getting a reply immediately, pipelining will enable you to create a batch command execution and run them on the server simultaneously.
The primary purpose of pipelining is to improve protocol and Redis performance. Furthermore, since all commands are first organized on the client-side, it can reduce the Round Trip Time required for the client to send a request, the server to process it and return a response to the client.
Redis provides us with a list data structure to store a collection of items. It is closely similar to a typical array in most programming languages. Once you add an element to a list, Redis will assign an index value starting at index 0.
Let us learn how we can use and work with lists in Redis.
Redis is an in-memory, key-value pair database that is highly flexible in a wide range of scenarios. In addition, it provides a collection of primitive types that make it versatile as a caching mechanism or message broker.
Let us learn how we can connect Redis with Ruby application.
Java provides a concept of methods that assist us in time management by means of code reusability. If we talk about the user-defined methods, we have to create/write them once and can utilize them again and again. In java, a method is nothing but a set of instructions that comes into action only when someone calls it.
A java method also known as a function is a block of code/instructions that may or may not take the parameters as input and returns some output. Moreover, the specified block of code will execute only when someone calls/invokes it. In java, a method can be created by specifying the access modifier, its return type followed by the user-defined method name. To call a method, we need to specify the method name followed by small brackets().
Reversing a list in Java today is not straightforward. That is why this article is written. Technically, a List in Java is an interface. An interface is a class with method signatures that do not have definitions. A class has to be implemented from this interface before objects of the implemented class can be instantiated. In the implemented class, the methods are defined.
There is a class, still called List, in Java. However, this class is meant for string elements for the list. A list does not only have to be made up of strings. A list can consist of all floats, all doubles, all integers, etc. Each of these types, would need to be reversed, depending on the problem at hand. So this class is not mentioned any further in this article for the string List. Reversing a list in this article refers to the List interface made into a class and an object.
There are Java predefined list classes implemented from the List interface. These list classes are: AbstractList, AbstractSequentialList, ArrayList, AttributeList, CopyOnWriteArrayList, LinkedList, RoleList, RoleUnresolvedList, Stack, and the Vector.

This talk is about a secure way to transfer information, to ourselves and others, that uses a cryptography protocol called SPAKE2.
Australian company Morse Micro MM6104 and MM6108 Wi-Fi HaLow SoCs should offer some competition to the Newracom NRC chips found in all 802.11ah WiFi HaLow boards and devices released so far.
Both MM610x chips have similar features, but the MM6104 SoC supports 1/2/4 MHz channel bandwidth for up to 15 Mbps data rate – just like the Newracom NRC7292 chip -, while the more powerful MM6108 can handle a data rate of up to 32.2 Mbps thanks to 1/2/4/8 MHz channel bandwidth.
So last week my radio got stuck on its locked mode for some reason, which meant I couldn't turn it on, off, or do anything really. So I unscrewed the back and took off the antenna, but the switch that activated the locked mode was deep in the circuitry where I couldn't get to it, so looked it like it was toast. Today it started to randomly work again, sweet, but now the signal strength was only half as strong. So I unscrewed it again, looked closely, and noticed that where the antenna sits is completely chewed up, missing! Looked like it happened over time, but it was always working fine until I took it apart! If you touch it to some random pieces of metal anywhere on the inside, it actually gets perfect strength, yet theres nothing where the antenna is actually supposed to sit.
The explosive growth seen by Microsoft's Windows 11 operating system over the past few months is beginning to slow, new figures suggest.
The latest report from AdDuplex shows that Windows 11 user numbers are levelling out, perhaps suggesting Microsoft needs to up its game with some new updates or additions to the platform soon.
For the month of March 2022, Windows 11 took just 0.1% market share from other editions of Microsoft's software, accounting for 19.4% of the overall usage, with a further 0.6% using a Windows 11 Insider build.
Many are outraged at recent Republican laws enacted in many states that affect voting rights. But we all should be outraged at Democrats in New York who have enacted laws to undermine voting rights in our state.
These new rules ensure that only the elites in New York can run for office, that hundreds of thousands of New Yorkers will be prevented from voting for whom they truly support, limiting our choice and therefore silencing our voice. Over 250,000 New Yorkers voted for alternatives parties in 2018. Ending achievable candidate access to the ballot, as well as voter access to the election process disenfranchises voters for alternative parties like those we represent, the Green Party and the Libertarian Party.

I've got several websites building with Eleventy, and I'm working on setting it up to automatically build the same sites as Gemini capsules. One set of source documents in Markdown, two formats!
There may be an easier way to do this, but here's what I've got so far:
Copy .eleventy.js to gemini.js
Create a _gemini_includes folder for the Gemini layouts (which are going to be a whole lot simpler!)
This talk is about the many services we commonly use in our daily lives that have FOSS alternatives that support federation. It will look into some of the privacy-respecting options that we can use instead of those offered by Big-Tech.
In an important 2018 decision, the Federal Circuit sided partially with Berkheimer on a procedural eligibility grounds — finding disputed questions of material fact as to whether aspects of the claimed invention were “well-understood, routine, and conventional to a skilled artisan.” Berkheimer v. HP Inc., 881 F.3d 1360 (Fed. Cir. 2018), cert denied 140 S.Ct. 911 (2020). The district court had invalidated claims 1-9 as ineligible and 10-19 as indefinite. The appellate panel vacated that decision as to claims 4-7 but otherwise affirmed.
Professor Robert E. Mikos takes the USPTO to task in his recent Vanderbilt Law Review article, "Unauthorized and Unwise: The Lawful Use Requirement in Trademark Law" (pdf here). He charges that "[i]n demanding compliance with sundry nontrademark laws, the PTO has lost sight of the statute it is supposed to administer." There is no requirement of lawful use in the Lahnam Act and, he argues, there shouldn't be. "Making registration or protection conditional on compliance with nontrademark laws does nothing to further the aims of trademark law. To refocus the PTO's attention on the core issues of trademark law, the lawful use requirement must go."
The Board has re-designated this opinion as precedential. In a 51-page opinion, the Board affirmed a refusal to register the product configuration shown below, for "handbags," finding the design to be generic and, alternatively, lacking in acquired distinctiveness: "Handbags embodying the proposed mark are so common in the industry that such product design is not capable of indicating source and ... Applicant's proposed mark is at best a minor variation thereof." The applicant's alternative Section 2(f) claim failed due in part to the same lack of exclusivity of use. In re Jasmin Larian, LLC, 2022 USPQ2d 290 (TTAB 2022) [precedential] (Opinion by Judge Martha B. Allard).
The USPTO is seeking applications for the position of Supervisory Managing Interlocutory Attorney at the TTAB. The detailed announcement may be found here at the USA Jobs website. The deadline for applications is April 7, 2022.
Although Warhol is dead, his art, legacy, copyrights, and potential copy-wrongs live on. In the 1980s, Warhol created a set of silkscreens of the musician Prince. Prince did not personally model for the prints. Rather, Warhol worked from a set of studio photographs by Lynn Goldsmith. Apparently Vanity Fair commissioned Warhol to make an illustration for its 1984 article on Prince. As part of that process, VF obtained a license from Goldsmith, but only for the limited use “as an artist’s reference in connection with an article to be published in Vanity Fair Magazine.” The published article acknowledges Goldsmith. As part of that process, Warhol created a set of 16 Prince prints. Those have been sold and also reproduced in various forms in ways that go well beyond the original license.
