      • VermadenSplit Audio Files into Parts

        I recently got in the need of splitting quite large amount of audio files into smaller equal parts. The first thought that came to my mind was – probably thousand or more people had similar problem in the past so its already solved – so I went directly to the web search engine.

        The found solutions seem not that great or work partially only … or not work like I expected them to work. After looking at one of the possible solutions in a bash(1) script I started to modify it … but it turned out that writing my own solution was faster and easier … and simpler.

        Today I will share with you my solution to automatically split audio files into small equal parts.

      • Jim NielsenA Previous Sibling Selector

        In natural language, what I wanted was: “select every

        element that directly precedes an <hr> element and style the <a> link inside of it.”

        I know how to select the next sibiling of an element with div + p.

        And I know how to select any adjacent sibling of an element (which follows it) with div ~ p.

        And I learned how to select an element when it only has one child with p:only-child a (even though they are the only element on their line, markdown will wrap the [link](#) elements in a paragraph tag).

        But how do I select the previous sibling of an element? Something like p:before(hr) which would select all paragraphs that precede an <hr> element.

      • OpenSource.comMake a temporary file on Linux with Bash |

        When programming in the Bash scripting language, you sometimes need to create a temporary file. For instance, you might need to have an intermediary file you can commit to disk so you can process it with another command. It's easy to create a file such as temp or anything ending in .tmp. However, those names are just as likely to be generated by some other process, so you could accidentally overwrite an existing temporary file. And besides that, you shouldn't have to expend mental effort coming up with names that seem unique. The mktemp command on Fedora-based systems and tempfile on Debian-based systems are specially designed to alleviate that burden by making it easy to create, use, and remove unique files.

        SystemTap allows developers to add instrumentation to Linux systems to better understand the behavior of the kernel as well as userspace applications and libraries. This article, the first in a two-part series, shows how SystemTap can reveal potential performance problems down to individual lines of code. The second part of the series will describe how a SystemTap performance monitoring script was written.

        While writing or editing text in LibreOffice, there are times where you need to change the color of the text or the background. LibreOffice comes with its own set of color palette that you choose the color from and it is easily accessible from the toolbar. The problem is that if you want to use a custom color which is not available in the palette, you are out of luck because there are no visible options for you to add your own color to the palette.

        There is no better computing environment than the one availed by a Linux operating system distribution. This operating system environment gives its users a complete computing experience without too much interaction with the GUI (Graphical User Interface). The more experienced you are with Linux the more time you spend on the Linux command-line environment.

        The command-line environment is efficient enough to handle OS-centered tasks like file editing, configuration, and scripting. A command-line text editor like the Vim editor makes it possible to perform such tasks.

      • CitizixHow to Create AWS VPC Peering in same account/region using Terraform

        Amazon VPC peering enables the network connection between the private VPCs to route the traffic from one VPC to another. You can create VPC Peering between your own VPC with the VPC in the same region or a different region or with other VPCs in a different AWS account in a different region.

        AWS create peering connection by using the existing infrastructure of the VPC. VPC peering connection is not a form of gateway or VPN connection. It helps to make easy to transfer the data from VPC to VPC.

        In this guice, it is assumed that the VPCs that you want to peer have been created. If you need help creating a VPC checkout this guide. We need to create the peering request from the peering owner VPC, accept the peering connection request in the accepter account and update the route tables in both the VPCs with entries for the peering connection from either side.

        Darktable is a free and open-source photography application program and raw developer. Rather than being a raster graphics editor like Adobe Photoshop or GIMP, it comprises a subset of image editing operations specifically aimed at non-destructive raw image post-production. In addition to basic RAW conversion, Darktable is equipped with various tools for basic and advanced image editing. These include exposure correction, color management, white balance, image sharpening, noise reduction, perspective correction, and local retouching. As a result, Darktable is an incredibly powerful tool for photographers of all experience levels. Best of all, it is entirely free to download and use.

      • Linux Shell TipsHow to Create a Sudo User on Fedora Linux

        Fedora Linux is not a new name in the world of computing. This Linux operating system distribution has Red Hat as its primary sponsor. Red Hat made its development possible via the Fedora Project. Through free and open-source licenses, Fedora hosts a variety of distributed software.

        This Linux distribution also functions as an upstream for the Red hat Enterprise Linux Community version. The latter statement implies that the Fedora Project is a direct fork for Red Hat. In other words, Red Hat directly borrows its features’ implementation from Fedora.

        • Liam ProvenWhy I think the GNOME designers are incompetent

          But GNOME folk didn't know how to do this. They don't know how to do window management properly at all. So they take away the title bar buttons, then they say nobody needs title bars, so they took away title bars and replaced them with pathetic "CSD" which means that action buttons are now above the text to which they are responses. Good move, lads. By the way, every written language ever goes from top to bottom, not the reverse. Some to L to R, some go R to L, some do both (boustrophedon) but they all go top to bottom.

          The guys at Xerox PARC and Apple who invented the GUI knew this. The clowns at Red Hat don't.

          There are a thousand little examples of this. They are trying to rework the desktop GUI without understanding how it works, and for those of us who do know how it works, and also know of alternative designs these fools have never seen, such as RISC OS, which are far more efficient and linear and effective, it's extremely annoying.

      • Matt RickardHistory of Version Control Systems: Part 1

        First-generation version control systems made collaboration possible, but it was painful. Deleting, renaming, or creating new files wasn't easily done. Tracking files across multiple directories as part of one project was impossible. Branching and merging were confusing. Locks worked by copying a file with read-only or read-write UNIX permissions. Inevitably, programmers didn't want to wait for someone else to finish editing, so they got around the lock system with a simple chmod.

        The two widely used first-generation version control systems were SCCS and RCS.

However, the MOAD also showcased things like cut-and-paste text editing, a point-and-click interface, video conferencing, and even online collaboration à la Google Docs. One of the innovations shown that for some reason didn’t stand the test of time was the chorded keyboard: an input device with five keys that can be pressed simultaneously in different combinations, the same way you would play chords on a piano.

        • Rohan KumarTwo types of privacy

          Threat modelling provides important context to security and privacy advice. Measures necessary to protect against an advanced threat are different from those effective against unsophisticated threats. Moreover, threats don’t always fall along a simple one-dimensional axis from “simple” to “advanced”. I appreciate seeing communities acknowledge this complexity.

          When qualifying privacy recommendations with context, I think we should go further than describing threat models: we should acknowledge different types of privacy. “Privacy” means different things to different people. Even a single person may use the word “privacy” differently depending on their situation. Understanding a user’s unique situation(s), including their threat models, can inform us when we select the best of approach. How do we choose between reducing a footprint’s spread and size?

        • Computer WorldLet’s put smartphone mics to better use

          In fact, the iPhone has quite a few sounds it is trained to listen for: fire alarms, sirens, smoke alarms, cats and dogs, appliances (though I'm not clear about exactly which appliances), car horns, doorbells, door knocks, glass breaking, kettles, water running, baby crying, coughing and shouting. It also has to deactivate “Hey, Siri” voice commands if it's listening for other sounds. It's not clear why that's the case; if the phone's already listening, why not just include the "Hey, Siri" command to the list of items to listen for?

          But what if this sound-recognition could be tweaked to do core IT and operational chores? Think of it as an option to customize the phone to listen for sounds specific to your company. Just like the classic machine learning example, could the phone hear a sound in a work area and say, “That sounds like the XYZ component in that huge piece of machinery is overheating.”

        • [Old] Current AffairsWhy This Computer Scientist Says All Cryptocurrency Should “Die in a Fire”

          UC-Berkeley’s Nicholas Weaver has been studying cryptocurrency for years. He thinks it’s a terrible idea that will end in disaster.

        • [Old] David RosenthalEE380 Talk

          Bitcoin is notorious for consuming as much electricity as the Netherlands, but there are around 10,000 other cryptocurrencies, most using similar infrastructure and thus also in aggregate consuming unsustainable amounts of electricity. Bitcoin alone generates as much e-waste as the Netherlands, cryptocurrencies suffer an epidemic of pump-and-dump schemes and wash trading, they enable a $5.2B/year ransomware industry, they have disrupted supply chains for GPUs, hard disks, SSDs and other chips, they have made it impossible for web services to offer free tiers, and they are responsible for a massive crime wave including fraud, theft, tax evasion, funding of rogue states such as North Korea, drug smuggling, and even as documented by Jameson Lopp's list of physical attacks, armed robbery, kidnapping, torture and murder.


          Despite all the cleverness and hype, the technology just isn't that good. It is both extraordinarily inefficient, and extraordinarily insecure. Nicholas Weaver points out that the "Ethereum computer" is 1/5000 as powerful as a Raspbery Pi. and that for the cost of 1 second of its use you can buy nearly 60 Raspberry Pis. Moxie Marlinspike points out that an NFT is a link to a file of metadata that links to the image it purports to represent, so neither is guaranteed to exist or be valid.
