How to install the Polo File Manager--and why you should

Filed under

The Linux desktop has plenty of options. There isn't a single application, that doesn't have multiple competitors at the ready. One perfect example is the file manager. There's Nautilus, Thunar, Dolphin, Konqueror, Midnight Commander, Krusader, PCMan—the list goes on and on. Add another to that list: Polo.

Shutter - Eyes Wide Tux

Filed under

Shutter is a very handy screenshot tool. I'm quite pleased. But then, it also has its tiny flaws that make it imperfect. Most notably, the workflow is slightly more intrusive than if and when you work with something like Spectacle or Gnome screenshot. In this regard, I need something with the flexibility of the former and the simplicity of the latter. Back in the day, I think KSnapshot was that tool.

Philosophy aside, because we've already said all that needs to be said on these other programs, on its own, Shutter is a respectable choice. Powerful, extensible, practical, with lots of good features and options, and the ability to tweak the settings. It allows you to take screenshots en masse, and it's definitely a smart choice for extensive use. I'd like to see a somewhat faster flow, and since the buttons are there, the use of native desktop plugins for image export. Other than that, a very pleasing surprise. Clearimage Screenshot Revival. Or something.

  • QEMU 4.0.0-rc1 is now available

    On behalf of the QEMU Team, I'd like to announce the availability of the second release candidate for the QEMU 4.0 release. This release is meant for testing purposes and should not be used in a production environment.

  • QEMU 4.0-RC1 Released - Packing Many Arm Improvements, EDID, Faster Crypto

    QEMU 4.0-RC1 was released today as the second test release for this forthcoming feature update to this important component of the open-source Linux virtualization stack.

    QEMU 4.0 has been a very busy cycle with working on EDID display support, support for many new Arm extensions, new MIPS CPU support, several additions on the RISC-V open-source processor ISA front, the x86 HAX accelerator now works for non-Darwin POSIX hosts like Linux and NetBSD, TPM enhancements, multiple threads for encryption/description with block storage encryption back-ends, TCG code generation improvements, and a range of other improvements.

  • Lyrics – Display Synchronized Song Lyrics on Media Players

    Every music lover likes to be able to access the lyrics of the songs they play because they would want to learn the words, sing along, or just clarify some phrases. Last time, I wrote about MusixMatch and Instant Lyrics, and today I’m introducing a nice alternative that goes by the simple name of Lyrics.

    Lyrics is a free open source lightweight floating application that displays lyrics of any media player that supports MPRIS-2. It is able to display the lyrics of any song you’re listening to by querying the track’s details using the MPRIS protocol, searching for and downloading its lyric file after which it displays the lyrics in a synced auto-scrolling mode.

    Lyrics features a simple UI with the options for using night mode and setting your theme and you can use it with YouTube in any Chromium-based browser that has the browser-playerctl extension installed.

    Vivaldi 2.4 is now available for download on Linux, Windows, and macOS with an impressive lineup of new features, including support for multiple user profiles.

    First and foremost, the number one highlight in this release is a new customization option for toolbars. Beginning with version 2.4, Vivaldi users can simply drag buttons between select toolbars to further tweak the interface of the browser, thus making sure it matches their expectations.

    You can even reposition the reload and the back buttons, so you can basically configure Vivaldi to look just the way you want.

Which are the most insecure languages?

Filed under

From top to bottom, technology is riddled with security errors. At the lowest level, we have hardware errors such as Intel's Meltdown and Spectre bugs. Just above those, we have programming language security holes, and boy, do we have a lot of those!

WhiteSource, an open-source security company, recently did a study of open source security vulnerabilities in the seven most widely used languages over the past decade. To find the bugs, the company used it language security database. This contains data on open-source vulnerabilities from multiple sources such as the National Vulnerability Database (NVD), security advisories, GitHub issue trackers, and open-source projects issue trackers.

  • 10 Excellent Free Linux Relational Databases

    A relational database matches data using common characteristics found within the data set. The resulting groups of data are organized and are much easier for people to understand. In such a database the data and relations between them are organized in tables. A table is a collection of records and each record in a table contains the same fields. Certain fields may be designated as keys, which means that searches for specific values of that field will use indexing to speed them up.

    The term relational database was originally defined by Edgar Codd, a British computer scientist, whilst working at IBM Almaden Research Center. He recognized that the concept of a relational database could be derived from the principles of relational algebra and relational calculus.

    A Relational Database Management System (RDBMS) is a Database Management System (DBMS) that is based on the relational model. Most database systems today are based on this type of system.

    A database is a vital system for any organization that stores mission critical information. The continual failure of a company’s database system can only lead to the demise of the organization – companies cannot do business without a working database system.

    To provide an insight into the quality of software that is available, we have compiled a list of 10 open source RDBMS. Hopefully, there will be something of interest here for anyone who wants to store data in an efficient way.

  • 10 Best lightweight browsers for Linux or Ubuntu

    Web Browsers, the day when they started making our lives easier by allowing us to crawl the internet to today’s world; they have been gone through numerous technological advancements. Browsers are quite advance to handle high-end graphics, online videos, apps and more without the help of third-party software. But this also has made them heavy in terms of consuming hardware resources, means more RAM and storage space. Such kind of browsers works well on good system configuration machines, however, Linux operating systems those are running on old PC or laptops or low configuration systems require light browsers with a minimal approach to work fast.

    Mainstream browser or shall I say the dominated one: Google Chrome that Linux users refrain themselves from instaling it on their machines is rather resourced consuming browser. This is the main reason why most of the Linux OS like Ubuntu, Linux Mint, Centos and more come with Firefox Mozilla but somewhere it still not that much lightweight as we need it to be. So, I have done some research and gathered some lightweight Linux browsers.

  • TenFourFox FPR13 SPR1 available

    TenFourFox Feature Parity Release 13 Security Parity Release 1 ("FPR13.1") is now available and live (downloads, hashes, release notes). The Pwn2Own vulnerabilities do not work on TenFourFox in their present form (not only because we're PowerPC but also because of our hybrid-endian typed arrays and other differences), but I have determined that TenFourFox-specific variant attacks could be exploitable, so we are patched as well. This should also reduce the risk of crashes from attempts to exploit mainline x86 Firefox.

    Meanwhile, H.264 support for TenFourFox FPR14 appears to be sticking. Yes, folks: for the first time you can now play Vimeo and other H.264-only videos from within TenFourFox using sidecar ffmpeg libraries, and it actually works pretty well! Kudos to Olga for the integration code! That said, however, it comes with a couple significant caveats. The first is that while WebM video tends not to occur in large numbers on a given page, H.264 videos nowadays are studded everywhere (Vimeo's front page, Twitter threads, Imgur galleries, etc.) and sometimes try to autoplay simultaneously. In its first iteration this would cause the browser to run out of memory if a large number of higher resolution videos tried to play at once, and sometimes crash when an infallible memory allocation fallibled. Right now there is a lockout in the browser to immediately halt all H.264 decoding if any instance runs out of memory so that the browser can save itself, but this needs a lot more testing to make sure it's solid, and is clearly a suboptimal solution. Remember that we are under unusual memory constraints because of the large amount of stack required for our JIT.

nikita 0.3 released

Filed under

We are pleased to announce that we have released 0.3 of nikita.

A high level overview of the work that has been carried out is detailed in:

You can also get an insight into the the work from the developer-notes

This is very much a incremental release. We have a had a look backwards on the code
and worked on bug-fixes and undertaken improvements. We introduce the browse capability, which
is useful when discussing structural issues with data. We have started support for
pagination and undertaken some experimental work on block chain integration. The project has
also spent a lot of energy on the interface standard and we drafted a description on how
business specific metadata should be supported. We have a good number of pull requests in, on
clarifying issues with the standard. We have also tested Evrys Noark core that claims compliance with the interface standard and are in dialog about issues there. This has shown that there is a further need to standardise the entry point to a Noark API.

We are discussing a lot of interesting stuff going forward and you are welcome to join us on #nikita. Going forward we are working on export, import, pagination, odata and business specific metadata. We are also looking at how a private collection of documents can be sorted and imported to a Noark core via the interface standard.

Thank you to everyone who has contributed to the project!

  • It's Time To Re-Vote Following The Botched 2019 X.Org Elections
    While there were the recent X.Org Foundation board elections, a do-over was needed as their new custom-written voting software wasn't properly recording votes... So here's now your reminder to re-vote in these X.Org elections. At least with the initial round of voting they reached a super majority and the ballot question of whether the X.Org Foundation should formally fold into its umbrella worked and that X.Org + hook-up passed so all is well on that front. But for the Board of Directors elections, that's where re-voting is needed with the voting software that now correctly records the votes.

Games: Lutris and More

  • Epic Games Store Now On Linux Thanks To Lutris
    While the Epic Games Store itself is not officially supported by the open source Linux operating system, a third-party gaming client has now made sure that you can access the store and launcher on your own distro. The Epic Games Store is now accessible on Linux via the Lutris Gaming client. The client is available to all Linux users, who in the past has provided the same users a way to play PC games without the need to have Windows installed in their machines. Although Linux is not necessarily the go-to platform when it comes to PC gaming, there is a very niche audience dedicated to making the platform work in favor of open-source and to counteract what could be perceived as a heavily Windows-biased PC gaming community. Linux gaming is somewhat tedious to the relatively casual or normal user, although there are some within the Linux community that advertise and try to foster its growth in terms of gaming, as there are some games that can run better on the operating system. That is to say, if you have a lot of patience to try and make it work.
  • You Died but a Necromancer revived you is good fun in a small package
    Sometimes, simplicity is what makes a game and in the case of You Died BaNRY that's very true. The game has little depth to it but makes up for that in just how frantic and fun it can be. The entire gameplay is just you (or you and friends) attempting to cross a small level filled with platforms, spikes and all sorts of crazy traps. It's ridiculously easy to get into as well, since the controls are so basic all you need to worry about is your movement.
  • Forager is a weirdly addictive casual grinding game that has mined into my heart
    I'm not usually one for games that have you endlessly wander around, collect resources, build a little and repeat but Forager is so ridiculously charming it's lovely.
  • DragonRuby Game Toolkit, a cross-platform way to make games with Ruby
    Now for something a little different! Ryan "Icculus" Gordon, a name known for many Linux ports and SDL2 teamed up with indie developer Amir Rajan to create a new cross-platform toolkit. Why was it created? Well, in a nutshell they both "hate the complexity of today's engines" and this toolkit was actually made to help ship A Dark Room for the Nintendo Switch, which shows how versatile it is.
