  • Saying Goodbye to ‘All Things Open’ Until Next Year

    We knew going in there would be a record number of speakers this year — 131 according to a count on the ATO website — and we learned on our way out — at the closing ceremonies — that this year’s attendance topped 1,700, much more than last year and nearly doubling the attendance from the first ATO in 2013. Todd Lewis, the master of ceremonies for the event — his official title, chairperson, doesn’t begin to describe what he does — said that next year they’re aiming for 2,500, a number they probably have a good chance of hitting.

  • Walmart goes to war with Amazon over open source

    Sigh. Another day, another useless open source project.

    This time it's Walmart, open sourcing its cloud technology to compete with Amazon Web Services (AWS). But, as David Linthicum writes, it's open source for all the wrong reasons.

    More pertinently, it's open source in all the wrong ways.

  • Bringing open source to Pentaho

    In any end-to-end proprietary platform, there’s fear in the community about support, accessibility and cost. However, thanks to acquisitions, Pentaho Corp. has showed it is ready to embrace a more open world.

  • Rogue Wave Software releases 2015 Open Source Support Report

    Rogue Wave Software released their 2015 Open Source Support Report, solidifying the company as a leader in the open source software (OSS) community and providing information on OSS package use that could only be gathered from their own database. Taking data from over 8,000 OSS packages, surveys, experiences, and experts from across different industries, this report brings a new level of visibility into OSS support reporting that has been lacking until now.

  • Non-free software can mean unexpected surprises

    I went to a night sky photography talk on Tuesday. The presenter talked a bit about tips on camera lenses, exposures; then showed a raw image and prepared to demonstrate how to process it to bring out the details.

    His slides disappeared, the screen went blank, and then ... nothing. He wrestled with his laptop for a while. Finally he said "Looks like I'm going to need a network connection", left the podium and headed out the door to find someone to help him with that.

    I'm not sure what the networking issue was: the nature center has open wi-fi, but you know how it is during talks: if anything can possibly go wrong with networking, it will, which is why a good speaker tries not to rely on it. And I'm not blaming this speaker, who had clearly done plenty of preparation and thought he had everything lined up.

    Eventually they got the network connection, and he connected to Adobe. It turns out the problem was that Adobe Photoshop is now cloud-based. Even if you have a local copy of the software, it insists on checking in with Adobe at least every 30 days. At least, that's the theory. But he had used the software on that laptop earlier that same day, and thought he was safe. But that wasn't good enough, and Photoshop picked the worst possible time -- a talk in front of a large audience -- to decide it needed to check in before letting him do anything.

  • Neo4j’s graph query language launches under standalone open-source license

    Neo Technology Inc. made a lot of new friends in the open-source ecosystem this morning after releasing the query language powering its hugely popular graph store under an open-source license. The move officially clears the way for other vendors to implement the syntax in their own systems.

    The openCypher project, as the startup refers to the free standalone implementation, already has several big-name supporters lined up on launch. The list includes providers such as Tableau Inc. and Tom Sawyer Software Inc. that have offered connectors for Neo4j long before the announcement of initiative as well as newcomers hoping to secure a seat on the graph bandwagon.

  • Notes from Flink Forward

    I was in Berlin last week for Flink Forward, the inaugural Apache Flink conference. I’m still learning about Flink, and Flink Forward was a great place to learn more. In this post, I’ll share some of what I consider its coolest features and highlight some of the talks I especially enjoyed. Videos of the talks should all be online soon, so you’ll be able to check them out as well.

  • How the Big Tent conversation changed OpenStack

    Because "cloud" means different things to different people, and because OpenStack tries to be all those things, individual OpenStack deployments can look very different from one another depending on many criteria. The "big tent" conversation, which has been ongoing in the OpenStack community for some time, strives to provide all of the answers for all of OpenStack's large audience.

  • How the hybrid cloud and open-source tech are changing IT

    The cloud is well on its way to becoming the standard model for IT, just sixteen years after it first formed. It couples flexibility, scale, and reliability to user-friendliness and ubiquity. It has created some of the world’s largest companies, as well as empowering some of the smallest. The cloud has changed the economics of providing and using services, bringing many new opportunities—and also a few teething problems, of course.

  • Letter: Open source textbooks can combat rising prices

    My name is Meghan Healey. I’m an undeclared freshman. Being on this exploratory track, most of my textbooks were relatively cheap, but they were still more expensive than they should be. If all textbooks were as “cheap” as my American Politics class, students would still have to pay at least $150 in order to have a proper education. This $150 could have been spent toward my tuition, my meal plan, or a plentiful amount of other academic expenses. Geology Textbook: $50. Environmental Science Packet: $30. Sustainability Book: $10. Freshman Seminar: $20. iClicker 2 for American Politics: $60. American Politics Textbook: $90 My total? $260. What should it be? Priceless.

  • Top 4 Java web frameworks built for scalability

    If you're writing a web application from scratch, you'll want to select a framework to make your life easier and reduce development time. Java, one of the most popular programming languages out there, offers plenty of options.

    Traditional Java applications, particularly web-facing apps, are built on top of a Model-View-Controller (MVC) framework, which follows the MVC software architectural pattern. Starting with Apache Struts, MVC frameworks have been a staple of Java development including such popular frameworks as WebWork, Spring MVC, Wicket, and GWT. Typically these applications host the view code on the server, where it is rendered and delivered to the client (web browser). Click a link or submit a form in your browser and it submits a request to the server, which does the requested work and builds a new view, refreshing the entire display in your client.

  1. My Homelab NAS on NixOS

    Installing NixOS was utterly painless. Using a combination of settings from the Arch Linux wiki (seriously wish I could get a printed copy of that thing, it's worth its weight in gold for how much weird arcane things you can learn from it), the NixOS wiki and copying things off of a Synology box's samba configuration file, I managed to trick everything into working and now all the machines on our tailnet can access the data on the NAS without too much trouble. Even iPhones and iPads thanks to the recent addition of SMB mounting on iP{hone|ad}OS. It also works over Tailscale too, so I can get into the NAS' files anywhere I have an internet connection.

  3. SSH alternatives for mobile, high-latency or unreliable connections

    SSH is the best option in most cases. It is widely used, usually installed by default, and clients exist for every platform. However, there are a few cases where you may want to consider an SSH alternative. I was recently looking for ways to solve these edge cases. These are my notes on alternative SSH servers.

  4. Unfortunately, damaged ZFS filesystems can be more or less unrepairable

    The second unfortunate aspect is that generally you can't repair this damage the way you can in more conventional filesystems. Because of ZFS's immutability and checksums, once something makes it to disk with a valid checksum, it's forever. If what made it to disk was broken or corrupted, it stays broken or corrupted; there's no way to fix it in place and no mechanism in ZFS to quietly fix it in a new version. Instead, the only way to get rid of the problem is to delete the corrupted data in some way, generally after copying out as much of the rest of your data as you can (and need to). If you're lucky, you can delete the affected file; if you're somewhat unfortunate, you're going to have to destroy the filesystem; if you're really unlucky, the entire pool needs to be recreated.

Kernel Space: Rollercoaster, Memory Management, Linux 5.16, and More

  • Rollercoaster: group messaging for mix networks [LWN.net]

    Even encrypted data sent on the internet leaves some footprints—metadata about where packets originate, where they are bound, and when they are sent. Mix networks are meant to hide that metadata by routing packets through various intermediate nodes to try to thwart the traffic analysis used by nation-state-level adversaries to identify "opponents" of various kinds. Tor is perhaps the best-known mix network, but there are others that make different tradeoffs to increase the security of their users. Rollercoaster is a recently announced mechanism that extends the functionality of mix networks in order to more efficiently communicate among groups. Tor uses multiple relay nodes, each of which only knows its predecessor and the node to pass the message on to. It relies on the difficulty of tracking messages through that path, but a sophisticated and well-placed adversary can do various kinds of traffic analysis to potentially match up traffic between two endpoints, thus drawing conclusions about the participants in the communication. To minimize latency, Tor nodes forward packets as quickly as they can, which may help eavesdroppers correlate the traffic. The Rollercoaster developers, Daniel Hugenroth, Martin Kleppmann, and Alastair R. Beresford from the University of Cambridge, used the Loopix mix network to validate their work. Loopix is different from Tor in that sacrifices latency in order to make traffic analysis even more difficult. The client endpoints in such a mix network send fixed-sized packets at a fixed rate; if there is no outbound traffic, a cover packet is sent that is indistinguishable from normal traffic. The packets are sent to the relay nodes, which independently delay each packet before passing it on to the next relay. All of that makes it much more difficult to correlate the traffic and identify communicating endpoints.

  • Some upcoming memory-management patches [LWN.net]

    The memory-management subsystem remains one of the most complex parts of the kernel, with an ongoing reliance on various heuristics for performance. It is thus not surprising that developers continue to try to improve its functionality. A number of memory-management patches are currently in circulation; read on for a look at the freeing of page-table pages, kvmalloc() flags, memory clearing, and NUMA "home nodes".

  • 5.16 Merge window, part 2 [LWN.net]

    Linus Torvalds released 5.16-rc1 and ended the 5.16 merge window on November 14, as expected. At that point, 12,321 non-merge changesets had been pulled into the mainline; about 5,500 since our summary of the first half of the merge window was written. As is usually the case, the patch mix in the latter part of the merge window tended more toward fixes, but there were a number other changes as well.

  • Intel SGX2 / Enclave Dynamic Memory Management Patches Posted For Linux - Phoronix

    While Intel's Software Guard Extensions (SGX) functionality has been present in CPUs going back to Skylake, it took until last year with Linux 5.11 for SGX support to finally be mainlined and required more than 40 rounds of review/revisions. Finally today Intel posted patches for bringing up SGX2 as the next iteration of Software Guard Extensions and already found in shipping processors. Intel SGX is about defining private memory regions "enclaves" that are encrypted and cannot be read/used by any other processes or the host. SGX can be used for some interesting secure computing scenarios but the belated kernel support as well as various possible security vulnerabilities / attacks have rather limited its scope so far. Earlier this year building off the prior SGX support in Linux 5.11, SGX was brought for KVM guest support in v5.13.

  • Pocket’s state-by-state guide to the most popular articles in 2021

    We’re just going to say it: it feels a little bit weird to wrap up 2021 because this year feels like three years in one and an extension of 2020 simultaneously. At some point in the near future, 2020 and 2021 will be studied in history books. While we can’t predict what the history books will say, we can analyze what defined this year for us. We do just that in Pocket’s Best of 2021 — the most-saved, -read and -shared articles by Pocket readers, spanning culture, science, tech and more. As we analyzed the winning articles, we wondered what we might learn if we looked at the data state by state.

  • Celebrating Pocket’s Best of 2021

    We aren’t the only ones putting out Top 10 content lists or Year in Reviews, but we’d argue these lists are different from the rest — a cut above. Pocket readers are a discerning bunch: they gravitate to fascinating long reads that deeply immerse readers in a story or subject; explainers that demystify complex or poorly understood topics; big ideas that challenge us to think and maybe even act differently; and great advice for all facets of life. You’ll find must-read examples of all of these inside these eclectic Best of 2021 collections, from dozens of trustworthy and diverse publications. The stories people save most to Pocket often provide a fascinating window into what’s occupying our collective attention each year. In 2019, the most-saved article on Pocket examined how modern economic precarity has turned millennials into the burnout generation. In 2020, the most-read article was a probing and prescient examination of how the Covid-19 pandemic might end.

  • Chromium Blog: Faster Chrome - Let The Compiler do the work

    Chrome is fast, but there's always room for improvement. Often, that's achieved by carefully crafting the algorithms that make up Chrome. But there's a lot of Chrome, so why not let computers do at least some part of our work? In this installment of The Fast And the Curious, we'll show you several changes in how we build Chrome to achieve a 25.8% higher score on Speedometer on Windows and a 22.0% increase in browser responsiveness. [...] It turns out that the compiler can make even more use of that profile data for PGO. (Not a surprise - once you know where the slow spots are, exactly, you can do a lot to improve!). To make use of that, and enable further improvements, LLVM has something called the "new pass manager". In a nutshell, it's a new way to run optimizations within LLVM, and it helps a lot with PGO. For much more detail, I'd suggest reading the LLVM blog post.

  • What is a managed IT service? | Ubuntu

    Technology is one of the main success factors for any organisation. A few decades ago, when technology (and life) were not as fast-paced as today, IT was more about keeping the lights on and maintaining business as usual operations. Today, the game has massively changed. On the roads that are ever-changing, innovation is what keeps the wheel spinning. If you think that the world is doing enough innovation today, then it would be very interesting to check the recent Growth & Innovation McKinsey report. This report shows that only 6% of executives are satisfied with innovation within their organisations, with the majority not being able to identify how to encourage innovation! So, how is innovation related to managed IT services and the speed at which organisations adopt new technologies? And even more, what is a managed IT service?
