Chef becomes 100% free software

LWN.net - Tor, 04/02/2019 - 15:10
Chef, the purveyor of a popular configuration-management system, has announced a move away from the open-core business model and toward the open-sourcing of all of its software. "We aren’t making this change lightly. Over the years we have experimented with and learned from a variety of different open source, community and commercial models, in search of the right balance. We believe that this change, and the way we have made it, best aligns the objectives of our communities with our own business objectives. Now we can focus all of our investment and energy on building the best possible products in the best possible way for our community without having to choose between what is 'proprietary' and what is 'in the commons.'"

9 Best Free Linux Digital Forensics Tools

tuxmachines.org - Tor, 04/02/2019 - 15:07

Digital forensics is a specialist art. It allows investigations to be undertaken without modifying the media. Being able to preserve and analyze data in a safe and non-destructive way is crucial when using digital evidence as part of an investigation, and even more so when a legal audit trail needs to be maintained. Digital forensics can be used in a wide range of investigations such as computer intrusion, unauthorised use of computers including the violation of an organisation’s internet-usage policy, gathering intelligence from documents and emails, as well as the protection of corporate assets.

We have extolled the virtues of open source software in many of our previous articles. The debate between open source and closed source software has often centered on factors such as freedom, reliability, interoperability and open standards, support, and philosophy.

In this instance, open source software offers a legal benefit, as it can increase the admissibility of digital forensic evidence. This is because open source tools enable the investigator and court to verify that a tool does what it claims and makes it easier to prove that the original drive has not been modified, or that a copy has not been modified.

Linux has a good range of digital forensics tools that can process data, perform data analysis of text documents, images, videos, and executable files, present that data to the investigator in a form that helps identify relevant data, and to search the data.

To provide an insight into the software that is available, we have compiled a list of 9 of our favorite digital forensics tools. Hopefully, there will be something of interest here for anyone who needs to undertake digital investigations.

Graphics: Blend2D, Intel and Panfrost Gallium3D

tuxmachines.org - Tor, 04/02/2019 - 15:02
  • Blend2D Reaches Beta As High Performance 2D Vector Graphics Engine

    Blend2D is a cross-platform C++ vector graphics library aiming to compete with the likes of Cairo.

    Blend2D allows for the drawing of 2D vector graphics in a high performance manner using a built-in JIT compiler to generate optimized pipelines at run-time. In many operations Blend2D can outperform Cairo and other 2D engines like what is offered by Qt5. The project has this performance page going over some of the advantages.

  • Intel Comet Lake Support Merged For Mesa 19.1

    With Intel Comet Lake support queued for Linux 5.2, Intel's open-source developers have queued the support into their Mesa code for their OpenGL/Vulkan user-space drivers.

    In March is when Intel began posting Comet Lake Linux support patches and now the kernel bits are in DRM-Next for Linux 5.2 while the user-space code is in Mesa 19.1 for the OpenGL/Vulkan drivers. Comet Lake is the latest Gen9-based revision succeeding Coffeelake/Kabylake.

    Given it's yet another take on Gen9, the Mesa support comes down to adding the new PCI IDs for the GT1 and GT2 parts and that is basically it.

  • Intel's Mesa Driver Now Supports Icelake Performance Counters

    The latest bit of Icelake "Gen 11" graphics enablement for the open-source Intel Linux graphics driver is supporting the performance counters/queries for exposing them through the OpenGL driver for the debugging/analyzing of performance bottlenecks. 

    The Icelake perf metrics were added for being able to expose the clocks, number of active execution units, cache misses, pipe activity, vertex/compute shader hardware threads dispatched, stalls, L3 throughput, and a variety of other counters.

  • Panfrost Gallium3D Is Now Running Kodi & Some Games For This Open-Source Mali Driver

    In the one year that the Panfrost Gallium3D driver has been coming together for open-source, reverse-engineered support for Arm Mali Midgard/Bifrost hardware, it's been making a lot of progress in what it's capable of running atop this Mesa driver.

    Panfrost driver lead developer Alyssa Rosenzweig shared that Panfrost has matured to the point that it can now run real-world applications like the Kodi HTPC software amd select OpenGL games like SuperTuxKart and Neverball. It's still a long way off the capabilities of the proprietary driver, which also supports OpenCL and Vulkan, but not too bad for a community-based, reverse-engineering driver effort with limited resources.

Games: Forager, Woodpunk, Atari VCS, Nintendo 3DS and More

tuxmachines.org - Tor, 04/02/2019 - 14:24
  • Forager, a pretty cute looking 2D open world mash-up of genres is coming to Linux

    Forager from developer HopFrog and publisher Humble Bundle looks like a pretty fun mash-up of different genres, inspired by the likes of Stardew Valley, Terraria & Zelda and it's going to support Linux now too.

    The developer originally said it was basically ready to release back in November last year, but due to contracts they needed to get the game ready for consoles to release at the same time as the PC versions. So while polishing it up, they've continued adding content to the game which has included Linux support! You can more info on that here.

  • Roguelike bullet-hell game Woodpunk is now properly out with Linux support

    Combining bullet-hell like gameplay with some roguelike elements, Woodpunk had a little delay in the Linux version which is now properly up and out.

    I did briefly mention Woodpunk in a previous article when it was supposed to release but they hit some sort of snag with their Publisher. The developer, Meteorbyte Studios, has since sent over a copy and I've actually had a lot of fun with this one.

  • The Linux-powered Atari VCS has gone through some design changes

    The Atari VCS team put out a new blog post and it goes over some changes to the design and it still looks pretty great.

    Now that they've already announced a delay and upgrade to AMD Ryzen, the Atari VCS team is once again talking about the design of the unit and how they've overhauled the construction method to make it more streamlined.

    It's worth noting, they're currently only showing renders of what it now looks like. As the pre-production models are on their way to their engineering team, which they say they will share actual photos when they have them.

  • Citra, the open-source emulator for the Nintendo 3DS is coming along nicely plus Flatpak support

    For those of you who want to check it out, Citra for emulating the Nintendo 3DS sounds like it's really progressing nicely.

    It's been a while since they posted an official status update, with the last way back at the start of December. This update which can be found here, goes over what they've been up to and how they've progressed against a poll they did on their Patreon for what their supporters wanted working.

    April is here already and here's your first look this month at what's going cheap for Linux gamers to pick up.

  • After failing Kickstarter funding, the Football-focused city builder Road to your City is now on Steam

    Road to your City is a city builder but it's not the usual kind, with a focus on building up a Football team to go along with your city it's pretty interesting to play.

    Sadly, the original Kickstarter failed to get much support so the developer has now put Road to your City on Steam in Early Access. I do love my city builders so I'm really happy to see more come to Linux officially and attempt to do something a little different and not just be "yet another".

  • A third Shelter game has been announced, this time you're an elephant

    Announced yesterday and it's very real (not an April Fools), Shelter 3 from Might and Delight won't be arriving until next year. This time you have a bigger role to play, "one where motherhood, social harmony and inheritance are the keys to prosperity", as you will take on the role of an elephant in part of a herd.

You can now buy an official Raspberry Pi keyboard and mouse

tuxmachines.org - Tor, 04/02/2019 - 13:20

The beauty of the Raspberry Pi is you don’t need to spend a fortune to get the barebones computer up and running. Once you’ve bought the Pi itself, you can use your own keyboard, mouse, monitor, power supply and so on, and spend as little (or as much) as you want to get any items you require but don’t currently have.

Raspberry Pi owners have been able to buy official Pi cases for a while, and now they can add an official keyboard and mouse too, so everything matches.

  • tint 0.1.1: New Styles

    With almost year passed since the previous 0.1.0 release, a nice new release of the tint package arrived on CRAN today. Its name expands from tint is not tufte as the package offers a fresher take on the Tufte-style for html and pdf presentations.

    This version adds new features, and a new co-author. Jonathan Gilligan calmly and persistently convinced me that there was ‘life beyond Roboto’ and I overcame the reluctance to offer other fonts. So now we have two additional reference implementations for Lato and Garamond which look stunning, as well as generally enhanced support for fonts, font families and entire LaTeX templates all via the standard YAML headers.

Cudo launches new OS, bringing smarter crypto mining to rig operators

tuxmachines.org - Tor, 04/02/2019 - 08:42

Cudo Miner, the crypto mining software application, has released a stand-alone operating system (OS) that can be quickly deployed or run directly from an external hard disk. The new CudoOS distribution includes all of the features included in Cudo’s original graphical user interface (GUI) miner, which is designed to make it easier to mine multiple coins with less configuration and maintenance.

In the bear market, few rig miners want to stay up all night to keep an eye on their mining setup – at least not between hard forks and new coins. With built-in benchmarking, overclocking, and the option to intelligently switch mining resources to the most profitable crypto currency, Cudo says the CudoOS distribution provides miners with the ability to quickly setup up recover a problematic rig with a ready-to-use USB stick.

[...]

CudoOS is available as an ISO image, based on a stripped-down distribution of Linux Ubuntu 18.04 with the essential AMD and Nvidia GPU drivers required to start mining pre-installed. Because it’s 4GB, Cudo says it can be loaded onto a USB stick that can be plugged into any Intel-based GPU mining rig and run straight from the disk.

Security: Updates, Sudo and Penetration Testing

tuxmachines.org - Tor, 04/02/2019 - 08:36
  • Security updates for Monday
  • Using sudo options to enhance security

    By taking the time to learn sudo's many options, you can make your system more secure with a little creativity.

    Thanks to Ubuntu, sudo is best known as a quick way to run commands as root. However, there’s far more to sudo than Ubuntu’s policy. In fact, sudo’s man page is over 2,400 lines long, covering a staggering number of situations -- some of which, like many powerful Linux commands, can get you in a lot of trouble if you are careless. Among sudo’s options are many that can greatly enhance security, especially if you take the time to be creative.

    Why would you want to enhance your security? The answer is that, from a security viewpoint, Ubuntu’s use of sudo can be viewed as a problem (although opinions do differ). As you may know, when sudo is configured the way it is in Ubuntu, you can use the password for your everyday account to log in to sudo and run root commands. The trouble is that any password for an everyday account is exposed in a way that the root account is not, especially on the Internet. That means that if the everyday account is compromised, the intruder gains root access, too, if sudo is set up on the system. The traditional separate root password is more secure, although less convenient. Fortunately, though, you can manage both convenience and security by taking the time to learn the details of sudo.

    If you’re in the UK and on the hunt for an affordable Linux desktop PC, do take a look at online tech retailer eBuyer.

    While shopping for something else from their website, I looked to see if the company sells anything preloaded with Ubuntu.

    And to my surprise, they do!

    Now, this shouldn’t have been as surprising as it was because eBuyer, currently celebrating its 20th anniversary, sold a range of cheap and cheerful Ubuntu laptops back in 2015.

  • Monthly News – March 2019

    Many thanks for your support and donations and also for your feedback and ideas. Today we’ll talk a little bit about some of the negative aspects of Free Software development, but before we do, I want to emphasize how lucky we are here at Linux Mint to have this community and this level of support. It’s not always easy to achieve what we want, sometimes it’s not even easy to define what we want to achieve. We can have doubts, we can work really hard on something for a while and then question it so much, we’re not even sure we’ll ship it. We can get demotivated, uncertain, depressed even by negative reactions or interactions, and it can lead to developers stepping away from the project, taking a break or even leaving for good. And then sometimes simply seeing people enjoy what we did can boost an entire team, whether it’s seeing happiness in an email/comment or getting a feeling of satisfaction after a constructive interaction which leads to a fix or an implementation.

    I personally haven’t enjoyed this development cycle so far. 2 of our most talented developers have been away. Boosting performance in the Muffin window manager hasn’t been, and still isn’t, straight forward. Feedback on the new website and logo brought a huge amount of incertitude. We’ll still have a great release in the end and we’ll still achieve plenty of improvements (we did already to a certain extent), but we need to be strong and remain confident and it’s not easy when so much time is invested into something and then a month later it’s not ready, or it causes other issues, or it might please some people but not others. For a team to work, developers need to feel like heroes. They want the same things as users, they are users, they were “only” users to start with. At some stage they decide to get involved and they start investing time, efforts and emotions into improving our project. What they’re looking for the most is support and happiness. They need feedback and information to understand bugs or feature requests and when they’re done implementing something, they need to feel like heroes, they literally do, that’s part of the reason they’re here really.

This IPO market is nothing like late 1990s craziness

tuxmachines.org - Tor, 04/02/2019 - 08:20

An unprofitable software company named VA Linux still holds the record for the largest one-day gain for an IPO. Shares skyrocketed nearly 700% on its debut day in December 1999.

That valued the company at $1.6 billion even though VA Linux had annual sales of only $17.8 million.

Proprietary: Master PDF Editor, Steam and Tropico 6

tuxmachines.org - Tor, 04/02/2019 - 08:17
  • Download Master PDF Editor 4 For Linux (Free To Use Version)

    Master PDF Editor is a proprietary application to edit PDF documents on Linux, Windows and macOS. It can create, edit (insert text or images), annotate, view, encrypt, and sign PDF documents.

    With version version 5, Master PDF Editor has removed some features from its free to use version, like editing or adding text, inserting images, and more - when using such tools, the application adds a big watermark to the PDF document unless users buy the full version (around $83).

    Master PDF Editor 4 though, which is free for non-commercial use with no restrictions (at least on Linux, I'm not sure about macOS and Windows), can still be downloaded and works well, even though it's not linked on the application official website.

  • A Half-Year Since Valve Released Steam Play For Linux, Its Marketshare Is Still Sub-1%

    With the start of a new month, Valve has just published their updated monthly Steam figures showing the Linux gaming market-share and more.

    For March 2019, they are reporting the Linux gaming population at 0.82% of their overall user-base. This number though is a bit iffy as at the same time they are saying that's a 0.00% change over the month prior... But for February 2019, they had been reporting a 0.77% Linux market-share, which would have been a 0.05% increase. As recently as earlier today they were still reporting 0.77% for February until these "unchanged" 0.82% result was posted for March.

  • Linux Journal at 25

    Most magazines have the life expectancy of a house plant.

    Such was the betting line for Linux Journal when it started in April 1994. Our budget was a shoestring. The closest our owner, SSC (Specialized System Consultants) came to the magazine business was with the reference cards it published for UNIX, C, VI, Java, Bash and so on.

    And Linux wasn't even our original focus. Phil Hughes, who ran SSC, wanted to start a free (as in speech, not beer) software magazine, which was hardly a big box office idea. I was a member of the email group doing the planning for that, which started, as I recall, in late 1993. Then, in early 1994, Phil announced to the group that he had made up his mind after finding "this Finnish kid" who had written a UNIX of sorts called Linux.

    It was clear to Phil, and to approximately nobody else, that Linux was going to kick the ass of every UNIX in the world, plus all other operating systems as well, including the big one headquartered a few miles away from SSC's office in Seattle.
