Quantum computing for everyone, a programmer's perspective

1 hour 18 min ago
About a week ago, IBM launched Quantum Experience. The cornerstone of this initiative is to make a real, working quantum computer available for anyone. This blog discusses Quantum Experience, gives the basics while trying to dwell as little as possible on Algebra or Physics and, at the end, we’ll build a simple algorithm and discuss the results.

Tips for tpp and patat

5 hours 53 min ago
You might be surprised to learn that there are programs for running presentations in a terminal.No, I don't mean opening PowerPoint or Impress slides one after the other, as images in a frame-buffered console. I mean presenting slides coded for the terminal, in a terminal. Interesting idea? It seems to be, because there are (at least) 8 terminal presentation programs for Linux. [..] I haven't tried them all, but I've found tpp and patat to be fairly easy to use. Below are a few tips on working with these two programs.

Do we really need swap on modern systems?

Wednesday 22nd of February 2017 07:15:26 AM
Swap space is a method by which an operating system can move information out of memory and store it elsewhere until it is needed again. Swap space can generally be thought of an extension of the computer's memory which lives on the hard drive. In the past, having swap space was important as computers had relatively little memory and could quickly run out of available RAM. Unused data could be punted to swap while more urgent tasks were handled in memory. These days though computers tend to have a lot of memory and it raises the question of whether there is any point in having swap space anymore and, if so, how much?

Mesos Is to the Datacenter as the Kernel Is to Linux

Wednesday 22nd of February 2017 03:49:35 AM
Necessity is the mother of invention. We needed our datacenters to be more automated, so we invented tools like Puppet and Chef. We needed easier application deployment, so we invented Docker. Of course it didn[he]#039[/he]t stop there. Ben Hindman, the founder and chief architect of Mesosphere, co-created Apache Mesos. In his keynote at MesosCon Asia 2016, Hindman relates how failures and elasticity led to the development of Mesos.

The Changing Face of Open Source Licensing

Wednesday 22nd of February 2017 12:23:43 AM
The GPL is the grandaddy of open source licenses, and is not only the license used by Linux, but is the license that gave birth to the open source movement. It was designed with the purpose of giving computer users control of their machines, guaranteeing that software would be freely available and modifiable by users. It has served that purpose well.

Internet-enable your microcontroller projects for under $6 with ESP8266

Tuesday 21st of February 2017 08:57:52 PM
To get started with IoT (the Internet of Things), your device needs, well, an Internet connection. Base Arduino microcontrollers don't have Internet connectivity by default, so you either need to add Ethernet, Wi-Fi shields, or adapters to them, or buy an Arduino that has built-in Internet connectivity. In addition to complexity, both approaches add cost and consume the already-precious Arduino flash RAM for program space, which limits what you can do.read more

Security Leftovers

  • Java and Python FTP attacks can punch holes through firewalls
    The Java and Python runtimes fail to properly validate FTP URLs, which can potentially allow attackers to punch holes through firewalls to access local networks. On Saturday, security researcher Alexander Klink disclosed an interesting attack where exploiting an XXE (XML External Entity) vulnerability in a Java application can be used to send emails.
  • Microsoft: no plans to patch known bugs before March [Ed: Microsoft is keeping open 'back doors' that are publicly known about, not just secret ones]
    Microsoft has no plans to issue updates for two vulnerabilities, one a zero-day and the other being one publicised by Google, before the scheduled date for its next round of updates rolls around in March. The company did not issue any updates in February, even though it had been scheduled to switch to a new system from this month onwards. It gave no reason for this, apart from saying: "This month, we discovered a last minute issue that could impact some customers and was not resolved in time for our planned updates today. "After considering all options, we made the decision to delay this month’s updates. We apologise for any inconvenience caused by this change to the existing plan." The Google-disclosed bug was made public last week, and is said to be a flaw in the Windows graphic device interface library that can be exploited both locally and remotely to read the contents of a user's memory.
  • Microsoft issues critical security patches, but leaves zero-day flaws at risk
    Microsoft has patched "critical" security vulnerabilities in its browsers, but has left at least two zero-day flaws with public exploit code. The software giant released numerous patches late on Tuesday to fix flaws in Adobe Flash for customers using Internet Explorer on Windows 8.1 and later, as well as Edge for Windows 10.

Red Hat News

  • Why upstream contributions matter when developing open source NFV solutions.
    When software is developed using open source methods, an upstream repository of the code is accessible to all members of the project. Members contribute to the code, test it, write documentation and can create a solution from that code to use or distribute under license. If an organization follows the main stream or branch of the upstream code their solution will receive all the changes and updates created in the upstream repository. Those changes simply “flow down” to the member’s solution. However, if a member organization forks the code — if they create a solution that strays from the main stream — their solution no longer receives updates, fixes and changes from the upstream repository. This organization is now solely responsible for maintaining their solution without the benefit of the upstream community, much like the baby salmon that took a tributary and then have to fend for themselves rather than remain in the main stream and receive the benefit and guidance of the other salmon making their way to the ocean.
  • HPE and Red Hat Join Forces to Give Customers Greater Choice for NFV Deployments
    Hewlett Packard Enterprise ( NYSE : HPE ) and Red Hat, Inc. ( NYSE : RHT ) announced today they are working together to accelerate the deployment of network functions virtualization (NFV) solutions based on fully open, production-ready, standards-based infrastructures. HPE plans to offer ready-to-use, pre-integrated HPE NFV System solutions and HPE Validated Configurations incorporating Red Hat OpenStack Platform and Red Hat Ceph Storage for communications service providers (CSPs).
  • Red Hat Joins the OpenPower Foundation
    As part of our commitment to delivering open technologies across many computing architectures, Red Hat has joined the OpenPOWER Foundation, an open development community based on the POWER microprocessor architecture, at the Platinum level. While we already do build and support open technologies for the POWER architecture, the OpenPOWER Foundation is committed to an open, community-driven technology-creation process – something that we feel is critical to the continued growth of open collaboration around POWER.
