TuxMachines: LibreELEC (Krypton) v8.1.0 BETA

Tuesday 15th of August 2017 04:28:28 PM

This is a BETA of our 8.2 release; a mid-year bump to enhance hardware support and capabilities. It adds 10-bit HEVC support for recent Intel GPU generations, Samba 4.6 which brings support for SMB2/SMB3, and several SSL issues are resolved in a switch to OpenSSL. We continue to refine firmware we embed; removing old and unused files to reduce image size while adding new drivers and firmwares based on team findings and user reports. Kodi is updated to 17.4-RC1 with minor bugfixes since v17.3.

TuxMachines: Programming: Debugging, Testing, Hacker-Proof Coding and More

Tuesday 15th of August 2017 04:21:29 PM
  • A history of microprocessor debug, 1980–2016

    Since the dawn of electronics design, where there have been designs, there have been bugs. But where they have been bugs, there inevitably was debug, engaged in an epic wrestling match with faults, bugs, and errors to determine which would prevail -- and how thoroughly.

    In many ways, the evolution of debug technology is as fascinating as any aspect of design; but it rarely receives the spotlight. Debug has evolved from simple stimulus-response-observe approaches to sophisticated tools, equipment, and methodologies conceived to address increasingly complex designs. Now, in 2017, we sit at the dawn of a new and exciting era with the introduction of debug over functional I/O.

    This is the culmination of decades of hard work and invention from around the globe. I've been involved in debug since 1984, so to truly appreciate the paradigm shift we're now experiencing in debug, it's useful to take a look back at the innovation that has taken place over the years.

  • Testing in production: Yes, you can (and should)

    I wrote a piece recently about why we are all distributed systems engineers now. To my surprise, lots of people objected to the observation that you have to test large distributed systems in production.

    It seems testing in production has gotten a bad rap—despite the fact that we all do it, all the time.

    Maybe we associate it with cowboy engineering. We hear "testing in production" and assume this means no unit tests, functional tests, or continuous integration.

    It's good to try and catch things before production -- we should do that too! But these things aren't mutually exclusive. Here are some things to consider about testing in production.

  • Hacker-Proof Coding

    At the University of Washington (UW) Medical Center, a radiotherapy system shoots high-powered radiation beams into the heads of patients, to treat cancers of the tongue and esophagus. Any software errors in the system could prove fatal, so engineers at the medical center have teamed with a group of computer scientists from the university to ensure the system will not fail, and that the beam will shut off if prescribed settings go out of tolerance.

    This is made possible by a process known as software verification, and verifying implementations of critical systems like that radiotherapy setup is one of the things about which Zachary Tatlock is passionate. Over three years ago, Tatlock was a Ph.D. candidate giving a talk at the university on his thesis research in program verification. The lead engineer for the medical center's radiotherapy team was in the audience, and asked Tatlock how they could apply verification to that system. "That probably helped me get hired," Tatlock recalls. Today, he's an assistant professor of computer science at the university and, with other colleagues and students at UW, has also been working with the team at the medical center ever since.

Reddit: Looking for an extremely basic inventory/cataloging app that will work with a barcode scanner

Tuesday 15th of August 2017 03:47:56 PM

So we have shipments of products come in, already barcoded. I'm trying to find an extremely simple piece of software that will allow my staff to scan the items, and then email a SKU count to their supervisor. Doesn't need to do anything else.

I realize I can do this in LibreCalc, but to do tallies I'd have to show them how to use pivot tables, which could be a recipe for errors.

Any other ideas?

TuxMachines: Security: Updates, Back Doors and More

Tuesday 15th of August 2017 02:29:10 PM
  • Security updates for Monday
  • Former NSA Official Argues The Real Problem With Undisclosed Exploits Is Careless End Users [Ed: Many are NOT "Undisclosed Exploits" but back doors]

    As leaked NSA software exploits have been redeployed to cause computer-based misery all over the world, the discussion about vulnerability disclosures has become louder. The argument for secrecy is based on the assumption that fighting an existential threat (terrorism, but likely also a variety of normal criminal behavior) outweighs concerns the general public might have about the security of their software/data/personal information. Plenty of recent real-world examples (hospital systems ransomed! etc.) do the arguing for those seeking expanded disclosure of vulnerabilities and exploits.

    Former Deputy Director of the NSA Rick Ledgett appears on the pages of Lawfare to argue against disclosure, just as one would have gathered by reading his brief author bio. Ledgett's arguments, however, feel more like dodges. First off, Ledgett says the NSA shouldn't have to disclose every vulnerability/exploit it has in its arsenal, an argument very few on the other side of the issue are actually making. Then he says arguments against exploit hoarding "oversimplify" the issue.

  • But that's not my job!

    This week I've been thinking about how security people and non security people interact. Various conversations I have often end up with someone suggesting everyone needs some sort of security responsibility. My suspicion is this will never work.

TuxMachines: Debian: Debconf17 and Reproducible Builds

Tuesday 15th of August 2017 02:25:41 PM
  • Consensually doing things together?

    I’d like to explore what motivates one to start a project and what motivates one to keep maintaining it. What are the energy levels required to manage bits of Debian as the project keeps growing. How easy it is to say no. Whether we have roles in Debian that require irreplaceable heroes to keep them going. What could be done to make life easier for heroes, easy enough that mere mortals can help, or take their place.

  • @DebConf17: Ad-hoc BoF: Debian for the Remote Desktop

    On Thursday at DebConf17, all people interested in using this or that Remote Desktop solution on Debian (as a server, as a client, as both) came together for a BoF.

  • Reproducible Builds: Weekly report #119

    29 package reviews have been added, 72 have been updated and 151 have been removed in this week, adding to our knowledge about identified issues.

  • "packages should build reproducibly" - after 4 years this work of many is in debian-policy now

    Four years ago Lunar held a BoF at DebConf13 which started the initiative in Debian. I only got involved in September 2014 with setting up continuous tests, rebuilding each package twice with some variations and then comparing the results using diffoscope, which back then was still called debbindiff and which we renamed as part of our efforts to make Reproducible Builds the norm in Free Software.

  • Debconf17

    I gave a talk entitled “Patterns for Testing Debian Packages”, in which I presented a collection of 7 patterns I documented while pushing the Debian Continuous Integration project, and were published in a 2016 paper. Video recording and a copy of the slides are available.

Reddit: Free VPN's

Tuesday 15th of August 2017 12:56:20 PM

Hello. So I have recently switched over to linux and I have been loving it. I especially love how light the distros are on hardware. I've been using kali linux practising intercepting internet traffic. And I have seen how easy it has been. I really don't want people to be able to steal my data without a lot of effort, so I was thinking of using a VPN. I have an old laptop. 2g of ram and less than 2ghz processing speed that I figured I could set up a VPN server on for 1 or 2 devices max. What would you recommend for both the distro and the VPN. They both have to be free because I don't really won't to pay for one unless I absolutely have to. I've heard the typical openVPN but I haven't had much luck with it. Any recommendationsand input would help. ( FYI Connection to the laptop can be Ethernet or WIFI. Doesn't rally matter to me)

Reddit: C# IDE?

Tuesday 15th of August 2017 12:34:39 PM

So MonoDevelop is just killing itself when I try and open anything, so I'm looking for a different IDE. Research brought up some Jetbrains stuff and various other programs, but they're either simple code editors or it's paid software.

Are there any C# IDEs I could use? All I need is something that will set up programs and classes for me and do the compiling.

Thanks for any help.

Oracle changes heart on Java EE

  • Oracle opens up Java EE
    Oracle continues to make progress Java EE 8, the enterprise edition for the Java platform, and moving forward it would like to advance Java EE within a more open and collaborative community. Specifications are nearly complete and the Java team expects to deliver the Java EE 8 reference implementation this summer. As the delivery of Java EE 8 approaches, Oracle believes they have the ability to rethink how Java EE is developed in order to “make it more agile and responsive to changing industry and technology demands.”
  • Oracle considers moving Java EE to an open source foundation
    With the finalization of the Java EE 8 platform on the horizon, Oracle on Thursday said it's considering moving Java Enterprise Edition technologies to an open source foundation. The move, Oracle said in a blog post, "may be the right next step, in order to adopt more agile processes, implement more flexible licensing, and change the governance process."
  • Oracle doesn't want Java EE any more
    Oracle wants to end its leadership in the development of enterprise Java and is looking for an open source foundation to take on the role. The company said today that the upcoming Java EE (Enterprise Edition) 8 presents an opportunity to rethink how the platform is developed. Although development is done via open source with community participation, the current Oracle-led process is not seen agile, flexible, or open enough. ”We believe that moving Java EE technologies to an open source foundation may be the right next step, to adopt more agile processes, implement more flexible licensing and change the governance process,” Oracle said in a statement.
