TuxMachines: Open Source Tool ‘Rethinks’ Databases

Thursday 11th of August 2016 04:04:07 AM

An open source tool for writing queries and modeling data designed for use with the RethinkDB query language is being positioned as an alternative to developing applications using the ReQL query language.

Compose, a provider of hosted databases founded in 2010, acquired by IBM (NYSE: IBM) last year and incorporated into its Cloud Data Services unit, is pitching the ReQL alternative dubbed “Thinky.” The tool is described as an open source object relational mapper (ORM) designed for RethinkDB. IBM is offering RethinkDB and a batch of other hosted database services through its Compose Enterprise platform.

Reddit: How do I use WINE?

Thursday 11th of August 2016 04:04:05 AM

I have WINE on Ubuntu and I am trying to download Dishonored from Steam for a test run to see what it can handle. My problem is that Dishonored can only be downloaded on Windows and I don't know how to use WINE.

TuxMachines: Security News

Thursday 11th of August 2016 03:42:32 AM
  • Containerized Security: The Next Evolution of Virtualization?

    We in the security industry have gotten into a bad habit of focusing the majority of our attention and marketing dollars on raising awareness of the latest emerging threats and new technologies being developed to detect them. One just has to look at the headlines or spend fifteen minutes walking the show floor at a major security conference to see this trend. However, while we are focusing on what all the bad guys are doing, we’ve taken the eye off the ball of where our infrastructure business is going.

  • SDN Security Researchers State Their Case at Black Hat

    So say two of his grad students, Seungsoo Lee and Changhoon Yoon (left and right, respectively, in the photo above). But along with Shin, who’s now an assistant professor at the Korea Advanced Institute of Science and Technology (Kaist) and a research associate at the Open Networking Foundation (ONF), they’re hoping the industry is ready to start looking at the vulnerabilities that SDN introduces.

  • Widespread Linux Flaw Allows TCP Session Hijacking, Termination
  • Bungling Microsoft singlehandedly proves that golden backdoor keys are a terrible idea [Ed: Microsoft and backdoor should become synonymous. At every level, online and offline, Microsoft products booby-trapped with backdoors.]

    Microsoft leaked the golden keys that unlock Windows-powered tablets, phones and other devices sealed by Secure Boot – and is now scrambling to undo the blunder.

    These skeleton keys can be used to install non-Redmond operating systems on locked-down computers. In other words, on devices that do not allow you to disable Secure Boot even if you have administrator rights – such as ARM-based Windows RT tablets – it is now possible to sidestep this block and run, say, GNU/Linux or Android.

    What's more, it is believed it will be impossible for Microsoft to fully revoke the leaked keys.

    And perhaps most importantly: it is a reminder that demands by politicians and crimefighters for special keys, which can be used by investigators to unlock devices in criminal cases, will inevitably jeopardize the security of everyone.

    Microsoft's misstep was uncovered by two researchers, MY123 and Slipstream, who documented their findings here in a demoscene-themed writeup published on Tuesday. Slip believes Microsoft will find it impossible to undo its leak.

TuxMachines: Bedrock Linux Is Working To Combine Different Linux Distributions Into One

Thursday 11th of August 2016 03:39:56 AM

Bedrock Linux is a unique Linux distribution that offers the best elements of different distros. The users are allowed to build a rock-solid base derived from Debian, RHEL etc. After that, one has the choice to add different packages from multiple Linux distributions according to the need. Bedrock Linux is able to perform this trick by manipulating the virtual file systems.

Reddit: Wifi cards for home router/server

Thursday 11th of August 2016 01:39:10 AM

Hey everyone!

So, I have a home router/server that is just a linux (debian) based PC. I have a very old Wifi adapter in it now that was free from a family member many years ago. It's listed as lspci:

Network controller: Ralink corp. RT2800 802.11n PCI

A short description of the problem I'm having with it is that it's fairly slow no matter what I do with hostapd config files (I've tried many times over the years). It's listed as N, but I only ever get ~1.2 MBps, which leads me to believe it has always been in 802.11b mode. I use to have all my devices wired except for my phone, so this was fine, but that's not the case anymore.

So, I'm wondering what the state of current generation Wifi chipsets under linux, specifically when using them in a router with hostapd? Anyone have an 802.11ac pci-e adapter that just works with hostapd? Anything else to look for?

Thanks!

LXer: If you build it, they won't come: Why your project needs better marketing

Thursday 11th of August 2016 01:09:38 AM
FOSS (free and open source software) conferences are full of talks about how to improve your code, or how you manage your code, or what the latest and greatest languages and tools are. But a successful open source project is about more than good code. First, let's talk about what success is, because success isn't a guarantee.read more

Reddit: To my surprise, my Dad has been using Linux for over a year

Thursday 11th of August 2016 12:05:12 AM

I went to visit my parents yesterday. I was helping my Dad assemble some speakers and after we completed he went to boot up his computer. I recognized the login screen immediately! Sure enough, he typed in his password and LXDE was displayed before my very eyes.

I was utterly blown away. He reminded me that it was I that installed it for him. The story is that he was complaining about his desktop having viruses and being generally slow about a year and a half ago, when I was visiting for Christmas. So I installed Lubuntu for him. I thought I had removed it the next day, due to his complaints or confusion but I guess I had not and he's been using it this whole time.

Before you get too excited. My dad was not opening up the terminal, installing new apps or doing essentially anything other than opening up chrome and browsing his favourite sites such as youtube & kijiji. But I almost wanted to cry when he told me that he's had almost no complaints and it works better than his Windows 7 install before. The one issue my mom pointed out is that their HP deskjet 1010 wasn't working, but I resolved the issue in 5 minutes for them.

I imagine he's just been accepting the GUI software center prompts to update the system because it was fully updated as I was whizzing around and inspecting in disbelief.

TL;DR -I install Lubuntu on my Dad's computer 1.5 years ago -He's of Scottish descent and has too much inertia to remove it -Ends up enjoying it because the only application he needs is Chrome and it still works well

Reddit: A decent laptop for linux?

Wednesday 10th of August 2016 10:33:52 PM

Hey guys!
I'm currently running a MBPr 2015 early version, but it grew tired to keep up with all the bugs associated with it for every major/minor update. I also have a gaming desktop that has a linux partition which is about to get replaced with arch.
So I'm thinking about getting another laptop to strictly run Linux on. Being a college student, I don't have a huge budget, but I think I can spend around 300~400 bucks. The only spec that I want a laptop to have is at least have 1600x1nnn resolution.
I don't mind getting a used/refurbished or whatever. Any recommendation would be greatly appreciated! Thanks!

Linux on Servers

  • Kontena Launches Container Platform, Banks Seed Funding
    Startup Kontena has launched a container and microservices platform that, it claims, is designed to be developer friendly, easy to install and able to run at any scale -- attributes that, Kontena says, differentiate it from the current crop of container platforms. The Menlo Park, Calif.-based company, founded in March 2015, has also raised $2 million seed funding from Helsinki-based Lifeline Ventures. It also has a clever name: Say it out loud -- cute, huh? According to the team at Kontena Inc. , the startup's container and microservices platform requires zero maintenance, is designed for automatic updates, and runs on any infrastructure, including on-premises, cloud and hybrid. Combined, those attributes make it an easy-to-use alternative to platforms such as Docker, Kubernetes, Heroku and Mesosphere, the company says.
  • Stabilizing the world of hot and fast containers
    Containers are moving targets in multiple ways. With multiple tools, frameworks, implementations, and use cases to accomplish any task, it can be a fast-moving chaotic container world, which is a natural consequence of being young and popular. The good news is that all of this creative incubation is hugely productive, and because it's all open source everyone gets to share the benefits of all of this fabulous creativity. The bad news is that it's a giant energized cat herd. How do we know what direction to take? Must we plan for the work we do today to be obsolete in a few months? And, what about portability? I'd like to provide a few insights into the future of containers, and the direction we can expect the state of the art technology to take.
  • How DIGIT Created High Availability on the Public Cloud to Keep Its Games Running
    Emmanuel & Ross: HA is achievable on the public cloud. In our case, we couple redundancy across Availability Zone (AZ) with monitoring and autonomous systems to ensure our games can keep running. Using only one AZ will not ensure HA, as that entire zone could fail for a short time. Each of our applications runs in multiple containers at the same time. They're are all being monitored to handle current load. When one container is down, another takes its place. The same applies for all parts of our infrastructure. All services are autoscaling and behind a service discovery system. On top of this, nodes in our cluster are deployed across multiple AZs, each of which being an isolated network with its own NAT gateway. This way we can survive a whole zone going down.

  • LinuxCon: How Facebook Monitors Hundreds of Thousands of Servers with Netconsole
    The original kernel documentation for the feature explains that the netconsole module logs kernel printk messages over UDP, allowing debugging of problems where disk logging fails and serial consoles are impractical. Many organizations will choose to use syslog as a way to track potential server errors, but Owens said kernel bugs can crash a machine, so it doesn't help nearly as much as netconsole. He added that Facebook had a system in the past for monitoring that used syslog-ng, but it was less than 60 percent reliable. In contrast, Owens stated netconsole is highly scalable and can handle enormous log volume with greater than 99.99 percent reliability. "Netconsole is fanatically easy to deploy," Owens said. "Configuration is independent of the hardware and by definition you already have a network."

Android 7.0 Nougat

  • Android 7.0 Nougat review—Do more on your gigantic smartphone
    After a lengthy Developer Preview program starting in March, the final version of Android 7.0 (codenamed "Nougat") is finally launching today. The OS update will slowly begin to rollout to devices over the next few weeks. This year, Google is adding even more form factors to the world's most popular operating system. After tackling watches, phones, tablets, TVs, and cars, Nougat brings platform improvements aimed at virtual reality headsets and—with some help from Chrome OS—also targets laptops and desktops.
  • Google Android 7.0 Nougat Review – Surprisingly Uninspiring
    Since the past couple of years, Android updates have hit a concrete wall. Feature additions have gotten pretty mundane while focus on under the hood changes have become key for Google. Obviously, that’s a good thing, for some folks out there, but it’s a approach that doesn’t stand the test of time really very well. Users get frustrated after seeing the same thing over and over again. Same is absolutely true when you compare Android 7.0 Nougat directly with its predecessor, Android 6.0 Marshmallow.
  • Android 7.0 Nougat review: longer battery life and faster operation
    Android 7.0 Nougat is the new version of Google’s mobile operating system, used by billions of devices around the world. It features longer battery life, improved multitasking and smarter notifications in a slimmed down and refined Android experience – following on the work done in last year’s version 6 Marshmallow It is faster, more polished and a subtly-better experience all-round. Apps install more quickly, the OS can be smaller in size and updates to Android can be installed on the fly, without having to wait for 10 minutes while it reboots, if you have a new device. The new Vulcan API graphics system is also baked in for better gaming performance and Nougat will support Google’s Daydream virtual reality system, eventually. Nougat is not, however, a major visual overhaul of Android. Those that have used Marshmallow on any of Google’s Nexus smartphones or devices with little in the way of modification to Android, such as the OnePlus 3, will instantly recognise it.
  • The Best New Features In Android 7 Nougat
    The OS formerly known as Android N is officially out today for a range of Nexus phones. Now dubbed “Android Nougat”, the new mobile operating system ushers in some noteworthy improvements and new productivity tools which we’ve outlined below. But first, here are the Nexus models that are currently supported by the update:

  • How to measure your community's health
    How do you measure the health of your community, identify problems, and track progress towards your goals? What should you be measuring? Last month we discussed vanity metrics, those metrics that might sound impressive on the surface, but ultimately give you little insight or guidance to improve the health and well-being of your community. This naturally begs the question: What should you be measuring? And as I mentioned last month, the obvious but annoying answer: It depends. The first and foremost dependency relates to the nature of your community and where you and your members want it to go.

  • Walmart, Comcast Hasten Innovation, Improve Agility With OpenStack
    As new technologies like applications and programming languages are introduced, it's important for companies to remain flexible and fast enough to adapt, which is why Walmart and Comcast have embraced OpenStack. By adopting OpenStack solution OneOps, Walmart doesn't have to spend unnecessary time writing code or automating new processes in order to keep up with new technologies, Andrew Mitry, OpenStack Lead at Walmart, explained today at OpenStack East 2016. Walmart already uses more than 3,000 applications and services and has more than 170,000 cores in more than 30 regions, with more than 60 Open Source products that are deployed more than 40,000 times each month. With OneOps, Walmart can automate low-level processes like load balance and firewalls using OneOps, which Mitry said frees up time and resources to manage more intricate processes that require manual oversight.
  • MySQL daddy Widenius: Open-source religion won't feed MariaDB
    MySQL daddy Monty Widenius has dismissed claims the MariaDB fork is veering away from open source. Rather, the chief technology officer of MariaDB corporation called his firm’s embrace of a commercial licence for part of MariaDB "critical" to delivering new revenue and for the continued development of open-source software. Widenius told The Register in an interview that he believes criticism of MariaDB’s commercial licence for its new database proxy sever, MaxScale 2.0, is motivated by a "religious" belief in free and open source software. Not that Widenius is against the belief per se, he told The Register, it’s just: "Religion doesn't put meat on the table."

FOSS in Government

  • Uganda eager to tap into open source
    Uganda's Ministry of ICT recently developed a FOSS (Free and Open Source Software) policy to regulate the deployment of open source software and use of open standards to accelerate innovation and develop local content. At the 7th African Conference on Free and Open Source Software (FOSS), organised in conjunction with Uganda's National Information Technology Authority (NITA-U) to encourage industry partnerships and uptake of OSS in East Africa, open software was recognised for its contribution to innovation. Frank Tumwebaze, Minister of ICT and National Guidance in Uganda, said, "Free and open software services will help my ministry to innovate better because it forms the platform (for) many of the innovative ideas. Free and open source software in Uganda is certainly something we have been talking about and I am sure we will do so even more in the next few days. Some of the things Uganda has put in place to harness the benefit from free and open source software include a Software Strategy and Policy in accordance with the United Nations Conference on Trade and Development's (UNCTAD) Trade, Services and Development expert meeting's determination that free and open source software is an inseparable component of the global technology ecosystem."
  • Ireland's govt IT: Recession and job cuts forced us to adapt
    Ireland was hit hard by the global financial crunch of 2007 and 2008. It was the first of the EU member states to slip into recession immediately following the bursting of the economic bubble. As the economy contracted, banks faced default and government debt increased, with Ireland eventually taking an €67.5bn loan from the European Commission, European Central Bank (ECB) and the International Monetary Fund (IMF) Falling tax income and the need to bail out banks saw the Irish government spending in other areas of public life. The government had introduced the Public Sector Recruitment Embargo in 2009, which stopped hiring of all civil servants across government and cut pay and pensions – in return for a promise of no compulsory redundancies.

Obviously, one is better off to have IT for all rather than paying monopolistic prices for IT for a few. In schools, that meant extending the life of IT, elimination of malware and re-re-reboots, freedom from paper, freight for paper, storage for paper, … For governments freedom from lock-in to M$ and “friends” saved huge sums which could have been better spent on hardware or employees. Sigh.
