  • New Vector to scale open-source alternative to WhatsApp and Slack, where users own their data

    New Vector has announced $8.5 million in funding to scale its open-source, secure communication network, a bid to revolutionise data privacy and ownership in the messaging app space. The investments come from European VCs who specialize in enterprise tech: Notion Capital, Dawn and firstminute capital. Necessary for understanding New Vector’s business is to first understand Matrix. Matrix is an open-source project, building a global network for decentralised communication. Users can collaborate securely via end-to-end encryption, and notably, they retain all ownership and control over their data.

  • New Vector raises $8.5 million to develop an open source Slack and WhatsApp

    Tech giants like Facebook, Google, Apple, and Microsoft needn’t be gatekeepers to communication. That’s the idea upon which Matrix, an open standard and decentralized protocol for real-time communication, was formulated. It’s designed to allow users of one service provider to communicate with users of different providers via online chat, voice over IP, and videotelephony, ideally as seamlessly as SMTP (Simple Mail Transfer Protocol) facilitates email exchanges across clients and services. Implementing the Matrix protocol at scale requires infrastructure and technical expertise, however — and that’s where startups like New Vector have carved out a niche for themselves. In a little over two years, the startup has helped to grow the Matrix network 400% to 11 million users across 40,000 deployments, including French and U.S. government agencies, Wikipedia parent Wikimedia, KDE, RedHat, and more.

  • Paris uses open source to get closer to the citizen

    Around 35 per cent of Paris’ 1,000 IT applications are Lutece-driven and 15 per cent are based on other open-source software, with the remaining 50 per cent using proprietary systems. As applications are upgraded or new ones added, Lutece and open-source tools will be deployed as much as possible, Lanouar said, noting that this approach enables greater autonomy and agility for the City, as well as the ability to be more transparent and create a better user experience for the citizen.

  • After Dallas County's TechShare software failure, the future must be open source

    There has been plenty of coverage of the very expensive failures of TechShare, Dallas County's attempt to create case-tracking software that could be used in any Texas criminal court. Like many battles over operations-level issues, it is easy to miss the forest for the trees. One basic principle of good governing was flagrantly violated in this instance: Government shouldn't be involved in a for-profit operation. TechShare's leadership sought profit, rather than to merely recoup costs. I hope members of both parties can agree this is a principle we should consciously adopt. A public discussion will help avoid future misadventures that cost the county $30 million for a hot plate of nothing. The term "crony capitalism" gets tossed around a lot, and it sometimes unfairly tarnishes good models of public-private partnerships. Crony capitalism usually means the government gives preference to certain favored private firms without seeking the best price (or quality) for a service or good. That preference is odious because it denies taxpayers the best price. Crony capitalism props up firms that would otherwise fail, using taxpayer money as insurance.

  • AI Researchers' Open-Source Model Explanation Toolkit AllenNLP Interpret

    Although the techniques are generic, AllenNLP Interpret is intended for use in NLP. Inputs to NLP systems are strings of text, usually sentences or whole documents, and the text is parsed into its constituent words or tokens. AllenNLP Interpret includes saliency maps that show each token's contribution to the model prediction; a use case for this might be explaining which words in a sentence caused its sentiment to be classified as positive or negative. The toolkit also includes two adversarial methods that show how changing the tokens in the input could affect the output. The first, HotFlip, replaces the input word that has the highest gradient with other words until the model output changes. The other attack, input reduction, iteratively removes the word with the smallest gradient without changing the output; this results in input texts that are "usually nonsensical but cause high confidence predictions."

  • Open Source Rules the World

    Not too long ago I attended Linux Foundation’s Open Source Summit in San Diego, and this declaration of world dominance (tongue in cheek) was a fairly prominent refrain throughout. From best practices in OS development to emerging technologies to getting started—how to create an open source strategy, sustain it, and the right path to developing an Open Source Program Office (OSPO). All open source all the time. What became abundantly clear to me through the cacophony of voices representing developers, technologists and enthusiasts is that at the center of all that is open source are three key components critical to ultimate success (however you define it): people, processes, and technology. [...] The entire tech space is being redesigned by a digital transformation and the emergence of new open source technology platforms. It’s a revolution of sorts, led by groundbreaking innovations in machine learning, open source IoT, cyber security, virtual reality, big data analytics, blockchain and open source development tools. Additionally, there’s technology to help you know what’s in your code and automate the detection and remediation of license compliance and security issues in your DevOps life cycle.

  • Open Source Seed, a Hoax or a Wake-Up Call?

    “Open source” is a trend in various industries. It started to take root in the software industry (Mozilla), followed by biotechnology (CAMBIA) and publishing, where the creative commons concepts have taken root. Several of these trends are based in an opposition against corporate power generated by exclusive rights provided by patents and copyright. Others have a positive goal, i.e. to enhance participation by a much wider population to generate, validate and share information (e.g. Wikipedia). The seed sector has a very good story to tell with regard to its contributions to societal goals, but in parts of society, the corporate image and the use of patents create questions, so we could expect that also our sector would be challenged. It is there now. The University of Wisconsin developed an Open Source Seed Initiative several years ago, which was followed in Germany more recently. Access to “freed” plant genetic resources is made conditional to users making them available under the same “open source” conditions – that no IP is vested. The system should thus go “viral” and “force” breeders to join and thus stop protecting their products through IP.

  • Satellite images and open-source programs for mapping during disasters

    A few weeks ago, the states of Assam and Bihar were reeling under floods. Over 200 people were reported dead, with at least 10 million (one crore) of the states’ residents estimated to have been displaced. To save more lives and prevent further infrastructural damage, search and rescue missions during such disasters need to be effective, and more importantly, need to be rapid. The answer to this may lie in space. Open-source access to satellite images and new technologies to process these images have been a significant breakthrough to help document the true extent of flooding. Getting this information in time is key to plan and conduct evacuation missions, response operations and damage assessments. The European Space Agency (ESA)’s Sentinel-1 mission and the web-based Google Earth Engine (GEE) platform are two recent developments that have helped timely capture and analysis of satellite information. A research team from the Indian Institute for Human Settlements (IIHS) used this combination (Sentinel and GEE) to come up with an illustrative example of how such mapping can be used in the future to help in rescue missions, through accurate mapping of flood extents.

Events: Fibre Optic Conference, All Things Open and HacktoberFest

  • Andile Ngcaba urges embracing open source

    Given the growth of data and the Internet of things, insofar as data is concerned, the fibre industry must adopt open source architecture in terms of designing and building networks. This is the sentiment shared by Andile Ngcaba, president of the FTTx Council Africa, at the annual Fibre Optic Conference that kicked-off at the Sandton Convention Centre yesterday. Ngcaba was speaking about the future of the industry and how to be part of it, pointing out that modern businesses are being built on open source, while modern telcos are going to be built on open source.

  • What to expect from Scylla Summit 2019

    Scylla (the company) takes its name directly from Scylla [pronounced: sill-la], a Greek god sea monster whose mission was to haunt and torment the rocks of a narrow strait of water opposite the Charybdis whirlpool. Outside of Greek history, Scylla is an open source essentially distributed NoSQL data store that uses a sharded design on each node, meaning each CPU core handles a different subset of data.

  • Licence to grill: A year on, MongoDB's Eliot Horowitz talks to The Reg about SSPL

    A year after its controversial switch to the Server Side Public License (SSPL), and with new products livening up the summer, MongoDB remains unrepentant. The change was aimed at making vendors selling a service using the company's code share the source of applications used to run the service as well as any tweaks. The move appeared to be aimed squarely at cloud vendors, content to "capture all the value and give nothing back to the community," as Dev Ittycheria, CEO of MongoDB, told us at the time. Elements of the open source community were less than impressed. The Open Source Initiative (OSI) rejected the company's attempts to get the licence approved and eventually MongoDB withdrew the thing from the process, although the company continued to use it for its own products. Indeed, at MongoDB's London .Local event, where we met co-founder and CTO Eliot Horowitz, the company was trumpeting the opening up of its Compass GUI for MongoDB under the SSPL.

  • The love and the lament: Percona CEO details state of open source data

    Open source has changed, obviously it has. Starting from its origins among the hobbyist programmers and hackers who dared to defy the proprietary Silicon Valley behemoths, the open community-centric model for software development has now been widely adopted by the commercial software sector. In many cases, open source has become the norm for modern platforms, tools and applications. But how has this affected the nature of open development and what impact has this shift left in its wake on the data landscape that we view today?

Stream processing is all about speed and cadence, so, the DataStax CDC Connector for Apache Kafka gives developers ‘bidirectional data movement’ between DataStax, Cassandra and Kafka clusters.

Security: WireGuard, SafeBreach and More

  • WireGuard Snapshot `0.0.20191012` Available
    -----BEGIN PGP SIGNED MESSAGE-----
    Hash: SHA256
    
    Hello,
    
    A new snapshot, `0.0.20191012`, has been tagged in the git repository.
    
    Please note that this snapshot is a snapshot rather than a final
    release that is considered secure and bug-free. WireGuard is generally
    thought to be fairly stable, and most likely will not crash your
    computer (though it may).  However, as this is a snapshot, it comes
    with no guarantees; it is not applicable for CVEs.
    
    With all that said, if you'd like to test this snapshot out, there are a
    few relevant changes.
    
    == Changes ==
    
      * qemu: bump default version
      * netns: add test for failing 5.3 FIB changes
      
      Kernels 5.3.0 - 5.3.3 crash (and are probably exploitable) via this one liner:
      
      unshare -rUn sh -c 'ip link add dummy1 type dummy && ip link set dummy1 up && ip -6 route add default dev dummy1 && ip -6 rule add table main suppress_prefixlength 0 && ping -f 1234::1'
      
      We fixed this upstream here:
      
      https://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git/commit/?id=ca7a03c4175366a92cee0ccc4fec0038c3266e26
      
      This is relevant to WireGuard because a very similar sequence of commands is
      used by wg-quick(8).
      
      So, we've now added some tests to catch this code path in the future. While
      the bug here was a random old use-after-free, the test checks the general
      policy routing setup used by wg-quick(8), so that we make sure this continues
      to work with future kernels.
      
      * noise: recompare stamps after taking write lock
      
      We now recompare counters while holding a write lock.
      
      * netlink: allow preventing creation of new peers when updating
      
      This is a small enhancement for wg-dynamic, so that we can update peers
      without readding them if they've already been removed.
      
      * wg-quick: android: use Binder for setting DNS on Android 10
      
      wg-quick(8) for Android now supports Android 10 (Q). We'll be releasing a new
      version of the app for this later today.

  • SafeBreach catches vulnerability in controversial HP Touchpoint Analytics software

    Now the feature is embroiled in another minor controversy after security researchers at SafeBreach said they uncovered a new vulnerability. HP Touchpoint Analytics comes preinstalled on many HP devices that run Windows. Every version below 4.1.4.2827 is affected by what SafeBreach found. In a blog post, SafeBreach Labs security researcher Peleg Hadar said that because the service is executed as "NT AUTHORITY\SYSTEM," it is afforded extremely powerful permissions that give it wide access. "The CVE-2019-6333 vulnerability gives attackers the ability to load and execute malicious payloads using a signed service. This ability might be abused by an attacker for different purposes such as execution and evasion, for example: Application Whitelisting Bypass Signature Validation Bypassing," Hadar wrote. [...] The company has long had to defend HP Touchpoint Analytics against critics who say it gives HP unnecessary access to users' systems. When it first became widely noticed in 2017, dozens of users complained that they had not consented to adding the system.
