9 Best Free and Open Source Linux Hex Editors

Filed under
Linux
OSS

A hex editor is a special type of editor that can open any type of file and display its contents, byte by byte. The “hex” in “hex editor” is short for hexadecimal, which is a base-16 number system. This type of editor lets you view and edit binary files. A binary file is a file that contains data in machine-readable form (as opposed to a text file which can be read by a human).

Since a hex editor is used to edit binary files, they are sometimes known as a binary editor or a binary file editor. If you edit a file with a hex editor, you are said to hex edit the file, and the process of using a hex editor is called hex editing.

Manage knowledge with BlueSpice, an open source alternative to Confluence

Filed under
OSS

Knowledge management is a key to success in modern enterprises—but it is not exactly easy to achieve. Keeping track of all relevant details across all employees is a huge challenge, especially in agile environments, which most companies say they are.

Most companies resort to buying wiki-like solutions, such as Confluence from Atlassian, which exposes them to the lock-in effect of proprietary software. But many would do well to consider BlueSpice, an open source alternative to Atlassian Confluence that has a noble ancestry: it's based on Wikipedia's MediaWiki.

Email is one of the primary communication channels among users. The Radicati Group is an organization which publishes quantitative and qualitative research on business and consumer usage for email, instant messaging, social networking, wireless email, and unified communications. Their research estimates that the total worldwide emails in 2020 is 306 billion.

The cost of spam is frightening, estimated to be approximately $50 billion each year. The tide of the daily spam is a continual thorn in the side for both providers and users. Spam is a waste of valuable network bandwidth, disk space and takes up users’ valuable time to declutter their mailboxes. Many spam messages contain URLs to a dubious website or websites, peddling fake pharmaceutical products, replicas, enhancers, or gambling. Alternatively, the URLs may be phishing attacks, for example taking an unwitting victim to a site which seeks to steal private information such as bank account login data.

Is Open Source a Religion?

Filed under
OSS

Is open source a religion? There is a persistent myth that free/open source software (F/OSS) supporters think of F/OSS as a religion. SUSE is the largest open source software company, so that would make us, what, a church with the cutest mascot?
Of course this is wrong and F/OSS is not a religion, though the idea of working in a hushed cathedral-like atmosphere with pretty stained glass and organ music is appealing. (Visit St. John’s Cathedral in Spokane, Washington, USA to see a real genuine full-sized pipe organ. When it hits the low notes it rattles your bones from the inside.) If I really want stained glass and my own cathedral I can have those for just because, so let us move on to what F/OSS is really about, and what the value is for everyone who touches it, like customers, vendors, learners, hobbyists, governments– you might be surprised at the reach of F/OSS and its affect on the lives of pretty much everyone.

  • WordPress Mobile Engineers Propose Dual Licensing Gutenberg under GPL v2.0 and MPL v2.0

    During a Q&A session at WordCamp Europe 2020 online, Matt Mullenweg mentioned that Gutenberg contributors were considering dual licensing for embedding Gutenberg in mobile apps, along with the requirement that they would need to get an agreement from all contributors. WordPress mobile engineer Maxime Biais has just published a proposal for discussion, recommending dual licensing the editor under GPL v2.0 and MPL v2.0.

    [...]

    Mobile app developers are limited by the GPL, because it requires the entire app to be distributed under the same license. The team is proposing dual licensing under MPL v2.0, a weaker copyleft license that is often considered to be more “business-friendly.” It allows users to combine the software with proprietary code. MPL v2.0 requires the source code for any changes to be available under the MPL, ensuring improvements are shared back to the community. The rest of the app can be distributed under any terms with the MPL v2.0 code included as part of a “larger work.”

  • NoSQL databases: what is MongoDB and its use cases?

    Databases like MongoDB, a NoSQL document database, are commonly used in environments where flexibility is required with big, unstructured data with ever-changing schemas. This post explains what a NoSQL database is, and provides an overview of MongoDB, its use cases and a solution for running an open source MongoDB database at scale.

  • What Cassandra users think of their NoSQL DBMS

    With the NoSQL market expected to be worth $22 Billion by 2026, big business is paying Apache Cassandra a lot of attention. While MongoDB dominates NoSQL, 52.71% to Cassandra's 9.73%, Cassandra, with its ability to deliver continuous availability, high performance, and scalability to large volumes of unstructured data, will always be a player. Now, if only there were more expert Cassandra administrators!

    A global survey of 1,404 Cassandra practitioners found a plurality thought the lack of skilled staff and the challenge of migration was blocking Cassandra's adoption. To be exact, 36% of users currently using Cassandra for mission-critical apps said that a lack of Cassandra-skilled team members was deterring its broader adoption.

    When asked what it would take for practitioners to use Cassandra for more applications and features in production, they said it needs to be "easier to migrate" and "easier to integrate." That's because "we don't have time to train a ton of developers, so that time to deploy, time to onboard, that's really key. All the other stuff, scalability, that all sounds fine," said a London-based senior Cassandra user.

    That may be in part because of those surveyed, 89% were using open-source Cassandra. If they were using DataStax, the most popular Cassandra distro, it might be a different story.

  • Olauncher gives your home screen an open-source, minimalist makeover

    Android's open, customizable nature is one of the things that attract a lot of enthusiasts to the platform. From manufacturer-specific tweaks to third-party default app replacements, there's usually a way to make your phone look and act how you choose. Olauncher is a new home screen replacement app that endeavors to bring an open-source, lightweight, and minimal setup to your phone.

    And minimal it is — there's time and date info up top, a list of apps below ... and that's it. The clock and app list can be set to left, center, or right orientations. A maximum of six app names can be displayed, but if you're the most minimal of minimalists, you can set it to show no apps at all. But wouldn't that render it useless? Not quite! By default, swiping to the left launches the camera and swiping to the right opens up the dialer, but you can customize these as you choose. A swipe up opens the full app list organized alphabetically.

8 Best Free and Open Source Console Email Clients

Filed under
OSS

For the traditionalists, emails remains a fundamental part of the operating system. Fortunately, there is a wide selection of free email software available on the Linux platform which is stable, feature laden, and ideal for personal and business environments.

The vast majority of Linux users would never be satisfied without access to a graphical user interface. However, even in 2020 there remain many reasons why console based applications can be extremely desirable.

Although console applications are very useful for updating, configuring, and repairing a system, their benefits are not only confined to system administration. Console based applications are light on system resources (very useful on low spec machines), can be faster and more efficient than their graphical counterparts, they do not stop working when X/Wayland needs to be restarted, and they are great for scripting purposes.

The vast majority of computer users depend on a graphical user interface, and fear the command line. However, the command line holds significant power and versatility. Commands issued from a shell offer system administrators a quick and easy way to update, configure and repair a system.

The benefits of the command line are not only confined to system administration. The ability to transverse the file system quickly, give more information about files and directories, automate tasks, bring together the power of multiple console tools in a single command line, and run shell scripts are just a few examples of how the command line can offer a potent, multifarious toolbox.

The great filter of open source projects

Moz/FF
OSS

So, with the recent layoffs at Mozilla — among other things — a bit of discussion on the sustainability of open source projects has been reignited. There was a wide range of takes: from “FOSS is dead” (no) to “we need to re-decentralize the internet” (yes). I could not quite help putting forth opinions on the matter myself and did so on a short twitter thread. Fundamentally though, the opinions expressed on this matter seem to almost talk past each other — and I think the reasons for this might be found in history of open source(1).

[...]

Another — later — project, that I am assuming to have been quite resilient and which I am assuming will continue to be quite resilient is gentoo linux: By requiring users to compile all software themselves, this distribution makes their users either give up on their installs or gets them at least halfway to be packagers (and for a distribution, packagers are contributors) themselves. Also, by not having to deal with binaries, gentoo reduces its infrastructure needs to a minimum. And even while there are some signs of downsizing at gentoo, I am hopeful that the flexibility mentioned above makes gentoo more sustainable and self-reliant than others for quite some time to come.

[...]

All of the above projects, commoditized their complements and this allowed users, who were not contributors to still benefit from the work of those who were as these contributors were interested in protecting the complement.

Open Source Lightweight Directory Access Protocol Solutions

Filed under
OSS

LDAP (Lightweight Directory Access Protocol) is an application protocol for accessing directory services. It runs on a layer above the TCP/IP stack incorporating simplified encoding methods, and offers a convenient way to connect to, search, and modify Internet directories, specifically X.500-based directory services. It is an open, vendor-neutral, industry standard application protocol. LDAP utilizes a client-server model.

This protocol is specifically targeted at management applications and browser applications that provide read/write interactive access to directories.

The main benefit of using an LDAP server is that information for an entire organization can be consolidated into a central repository. LDAP supports Secure Sockets Layer (SSL) and Transport Layer Security (TLS), so that sensitive data can be protected. LDAP servers are used for a variety of tasks including, but not limited to, user authentication, machine authentication, user/system groups, asset tracking, organization representation, and application configuration stores.

  • Best WordPress Backup Plugins 2020

    It is at most important to keep multiple backups of your WordPress site. In case the website is compromised or any plugin update breaks your site, WordPress backups can help you restore it quickly.

    Mainly, a WordPress site consists of three important parts, the database, user-created files such as plugins, themes, and uploaded files, and finally the WordPress core files.

    If anyone of these three parts is missing or corrupted, the website will not function properly or will not function at all. When we create a backup, we create a backup of the site database and the user-created files. WordPress core files can be downloaded and installed separately.

  • Parsing PAN-OS logs using syslog-ng

    Version 3.29 of syslog-ng was released recently including a user-contributed feature: the panos-parser(). It is parsing log messages from PAN-OS (Palo Alto Networks Operating System). Unlike some other networking devices, the message headers of PAN-OS syslog messages are standards-compliant. However, if you want to act on your messages (filtering, alerting), you still need to parse the message part. The panos-parser() helps you create name-value pairs from the message part of the logs.

    From this blog you can learn why it is useful to parse PAN-OS log messages and how to use the panos-parser().
