  • Hyperledger Releases ‘Ursa’ As An Open Source Blockchain Toolbox Library For Crypto Developers

    Blockchain organization Hyperledger created a stir in the crypto developer community earlier today by launching a platform called Ursa. Ursa is a modular, shared cryptographic library that will make life easier for blockchain developers.

    Ursa, which is written mostly in Rust, will introduce modularization and an API to the crypto community while also supporting Hyperledger’s most popular languages. The tool is expected to reduce duplicate development and speed up blockchain development while improving efficiency within the open source development community.

  • ONAP Releases Casablanca, Enhances Deployment Capabilities Across Open Source Networking Stack

    LF Networking (LFN), which facilitates collaboration and operational excellence across open networking projects, today announced continued progress to ease deployments across the open source networking stack. New platform releases from ONAP (Casablanca) and OPNFV (Gambia) bring additional support for cross-stack deployments across new and existing use cases such as 5G and Cross-Carrier VPN (CCVPN), as well as enhancements to cloud-native VPN. Additionally, the organization’s compliance and verification program recently announced its expansion into virtual network functions (VNF) testing and is now recruiting Beta participants. VNF testing will help ease deployment pains and improve VNF quality and interoperability across real-world deployments.
    “New and enhanced deployments of our platforms are popping up every day across the globe, and with tighter cross-community integration and an expanded compliance and verification program, we are well-positioned to facilitate innovative industry progress,” said Arpit Joshipura, general manager, networking, the Linux Foundation. “The latest releases of ONAP and OPNFV usher in a new era for LFN as the community continues to foster an expanding commercial ecosystem.”

Linux Plumbers Conference 2018 Videos Now Online

  • Linux Plumbers Conference 2018 Videos Now Online

    For those interested in some interesting and highly-technical talks about the Linux kernel and other low-level plumbing that makes up Linux systems, all of the Linux Plumbers Conference 2018 videos are now online.

    Linux Plumbers Conference 2018 happened back in mid-November in Vancouver. There were plenty of Linux kernel talks as well as micro-conference tracks about thermal, containers, networking, testing, and more. A majority of the upstream Linux kernel maintainers participated in this annual event and there was a lot of interesting content, some of which we've provided overviews of in various articles.

ps_mem Shows Per-Program Memory Usage On Linux

Unlike many other tools that report memory usage per process, ps_mem reports the RAM usage of programs. For example it shows how much RAM is used by all Chromium processes combined. The program developer notes that the ps_mem name is used for backwards compatibility, but a more accurate name would be coremem. The displayed RAM is calculated by adding the sum of private RAM and the sum of shared RAM for a program processes. Running ps_mem with no arguments shows a list programs and their RAM usage in ascendant order (from the lowest RAM usage to the highest). For each program it shows the private, shared, and total used RAM, as well as the number of processes. Swap information for each program can be shown as well, by using the -S option (sudo ps_mem -S).

OSS Leftovers

  • The State of Neural Machine Translation for Asian Languages
    Open source for Asian language NLP is getting more and more active, but it would be useful to have more projects that are both frequently updated and popular. Sometimes, code licensing plays a negative role, because many old projects are GPL (General Public License). Jieba, Rakuten MA, KoNLPy are some frequently-used libraries for CJK (Chinese-Japanese-Korean) NLP. (Lucy Park is a KoNLPy developer.)
  • Will your organization change itself to death?
    Organizations, open or otherwise, cannot spend every moment changing themselves. For one thing, doing so would mean abandoning whatever mission they purport to have. As the saying goes, "if you don't stand for something, you'll fall for anything." That adage, while most common in the context of political beliefs, is applicable here too.
  • Open source may be the future, but very few are writing it

    Open source may dominate the software we use to power the cloud, AI, and more, but a small percentage of developers do most of the coding. While it has long been true that for any given open source project, the vast majority of core contributions come from a cabal of committed developers, it seemed like the popularity of using open source would bleed into writing open source. Nope.

  • viewport and iphone reflow

    Something that’s annoyed me for some years is that all the web sites I build don’t work quite right with my iphone. Scroll down a page, visit a link, go back, and safari jumps back to the top of the page. Very annoying. Pretty much no other site I visit seems to have this problem, yet I couldn’t figure out what I was doing wrong since I’m barely doing anything at all. There are some support forum complaints about similar bugs, but mostly from several years ago, and mostly “solved: it works now” without explanation.

    Finally, figured out what seems to be the problem. The iphone introduces its own viewport meta tag, to define the screen dimensions, and control whether the user can zoom or not. A lot of sites abuse this to the point of unusability, so I very determinedly stayed clear. But without a viewport tag, safari is really dumb.

  • Categorizing OpenBSD Bugs

    I thought it would be interesting to see if something similar were true of OpenBSD bugs. I went through two years of OpenBSD errata for the most recent four releases (6.1, 6.2, 6.3 and 6.4) and categorized each bug.

  • Bug in French government’s WhatsApp replacement let anyone join Élysée chats

    Tchap is not intended to be a classified communications system—it runs on regular Android phones and uses the public Internet. But as the DINSIC, the French inter-ministry directorate for information systems that runs Tchap put it, Tchap "is an instant messenger allowing government employees to exchange real-time information on everyday professional issues, ensuring that the conversations remain hosted on the national territory." In other words, it's to keep official government business off of Facebook's and Telegram's servers outside France.

    Based on the Riot.im chat application from the open source project Matrix, Tchap is officially still in "beta," according to DINSIC. And that beta test is getting off to a rough start. Within two days, French security researcher Baptiste Robert—who goes by the Twitter handle @fs0c131y (aka Elliot Alderson)—had tapped into Tchap and subsequently viewed all of the internal "public" discussion channels hosted by the service.
