As businesses adopt cloud-native architectures, conversations will naturally lead to what we can do to make the database horizontally scalable. The answer will likely be to take a closer look at TiDB.

TiDB is an open source NewSQL database released under the Apache 2.0 License. Because it speaks the MySQL protocol, your existing applications will be able to connect to it using any MySQL connector, and most SQL functionality remains identical (joins, subqueries, transactions, etc.).

Step under the covers, however, and there are differences. If your architecture is based on MySQL with Read Replicas, you'll see things work a little bit differently with TiDB. In this post, I'll go through the top five key differences I've found between TiDB and MySQL.

When I started Gluu in 2009, I had no idea how difficult it would be to start an open source software company. Using the open source development methodology seemed like a good idea, especially for infrastructure software based on protocols defined by open standards. By nature, entrepreneurs are optimistic—we underestimate the difficulty of starting a business. However, Gluu was my fourth business, so I thought I knew what I was in for. But I was in for a surprise!

Every business is unique. One of the challenges of serial entrepreneurship is that a truth that was core to the success of a previous business may be incorrect in your next business. Building a business around open source forced me to change my plan. How to find the right team members, how to price our offering, how to market our product—all of these aspects of starting a business (and more) were impacted by the open source mission and required an adjustment from my previous experience.

A few years ago, we started to question whether Gluu was pursuing the right business model. The business was growing, but not as fast as we would have liked.

Elementary OS is currently riding high in the Distrowatch rankings and it has been a while since my last review so I thought it was high time I took another look.

The tag line at the top of the Elementary OS website reads as “The fast, open and privacy respecting replacement for Windows and macOS”.

In this review I am going to examine this claim in depth as well as other claims such as “Apps you need, without the ones you don’t”. The website states that the applications have been carefully considered to cater for your everyday needs so you can spend more time using your computer and less time cleaning up bloatware.

Without further ado lets separate the fact from the fiction and explore Elementary OS with a virtual magnifying glass befitting a well known sleuth. After all it is “Elementary” my dear Watson. (Sorry, couldn’t resist).

Recent past i was traveling to my hometown very often for my personal work and i was facing difficulties to write article on 2DayGeek due to unavailable of internet as i don’t have proper internet facility because we are staying in remote area.

I was thinking what is the alternate solution to fulfill this.

I did small google search for offline documentation tool and got the awesome tool called “Zeal”.

Yes, it’s true. It’s awesome tool and supports 194 application documents.

I’m very much comfortable to work with zeal documentation as i’m getting whatever i want it.

Also, we can use this if you want to save some bandwidth when you are running with bandwidth shortage. Also it won’t show any ads, it’s clean and easy to use.

• Night of the Blood Moon, a difficult action rogue-lite to now launch in January with Linux support

  Night of the Blood Moon, a very interesting looking action rogue-lite from developer Tyler McDermott is now going to release in January with full Linux support.

  What makes it sound interesting, is that the developer says the weapons aren't just guns with different attributes. As they said "Weapons in Night of the Blood Moon will completely change the way you play the game. How you position yourself, and which enemies pose the most threat. Hookshots, Boomerangs, and Spellbooks are the beginning of a growing inventory.". It sounds interesting so I'm quite excited to see more from it.

• Cryptojackers Come to Linux with a Brand-New Stealth-Like Crypto Mining Malware [Ed: This only impacts already-cracked machines -- an important distinction to be made -- and they blame "Linux" while calling Windows "PC"]

  Linux users are not immune from stealth cryptocurrency mining, also called cryptojacking, anymore. Japanese cryptosecurity company Trend Micro discovered that a cryptocurrency miner known as KORKERDS behaves in a strange way, with the potential to hide its activity from Linux users.

  Trend Micro posted information on its website that the route of infection is yet to be investigated. However, the mining malware might get installed onto the victim's computer through a compromised plugin or software download.

• OpenStack Expands With New Projects, Canonical’s CEO Is Not Thrilled About It

  For those who have been paying attention (and SDxCentral has been), the OpenStack Foundation has been expanding its scope beyond the basic compute, storage, and networking sub-projects of its cloud infrastructure software. Today at the OpenStack Summit in Berlin the group made it official, announcing that it will host new open source projects with a new governance framework.

  The OpenStack Foundation board approved the governance framework to incubate new pilot projects that are relevant to the open infrastructure community. As part of this new framework, the first four pilot projects are Kata Containers, Airship, Zuul, and StarlingX. All of these projects have been previously announced.

• Open source is growing up – and here’s how

  If you’re among those who still think that open source is just for hobbyists and academics, think again. Open source is mature now, both as a concept and as tools for building enterprise IT, and we have two major shifts in understanding to thank for that.

  The first key change is that there’s a much more mature understanding now of how the layers of IT architecture relate to each other – of what fits where, in other words. Instead of trying to do too much, adding in every feature or capability that might be related, open source projects have become more focused.

  For example, instead of misunderstanding them as rivals, we can now see OpenStack and Kubernetes for what they are. The former is an infrastructure layer, upon which you can run platform layers such as the latter.

• Open-source and cloud-native, Kubernetes paves the way for new companies to bring DevOps to data

  With less than two months left, 2018 is poised to go down in tech history as the coming of age for open-source software.

  Need evidence? Over the past 10 months, notable open-source enterprises MuleSoft Inc., Magento Inc., GitHub Inc. and Red Hat Inc. have been purchased for a combined $50 billion.

  Yet before jumping on the open-source bandwagon, observers would be wise to keep in mind that these technologies still depend on a sizable community of contributors to keep innovation fresh, and monetization of many open-source projects remains a struggle. So what is all the fuss about?

• Red Hat OpenStack Platform 14 coming soon with tighter Kubernetes integration

  Today, Red Hat has announced Red Hat OpenStack Platform 14, saying it will become available in the coming weeks. The firm says that the latest version, which is built on the OpenStack “Rocky” community release, more tightly integrates with the Red Hat OpenShift Container Platform which gives admins full control over their Kubernetes environments.

• Red Hat commits to Openstack for 'at least' 10 years

  While Red Hat understandably wouldn't discuss anything to do with the IBM mega-acquisition - for regulatory reasons - director of product management James Labocki and senior director for product management at Openstack Nick Barcet confirmed Red Hat's commitment to Openstack for at least the next "10 years".

  The open source giant today announced Openstack Platform 14, which Barcet said aimed to make Openstack a better platform to run container orchestration system Kubernetes on, while also helping to better manage the deployment of Red Hat's container platform OpenShift on bare metal, as well as easing the integration of OpenShift and Openstack at the networking and storage layer. This, says Barcet, is a landmark move for Red Hat because it is part of a new strategy to focus on its whole portfolio as a single entity rather than individual products.

• Mozilla shares how AV1, the new the open source royalty-free video codec, works

  Last month, Nathan Egge, a Senior Research Engineer at Mozilla explained technical details behind AV1 in depth at the Mile High Video Workshop in Denver. AV1 is a new open source royalty-free video codec that promises to help companies and individuals transmit high-quality video over the internet efficiently.

  AV1 is developed by the Alliance for Open Media (AOMedia), an association of firms from the semiconductor industry, video on demand providers, and web browser developers, founded in 2015. Mozilla joined AOMedia as a founding member.

  AV1 was created for a broad set of industry use cases such as video on demand/streaming, video conferencing, screen sharing, video game streaming, and broadcast. It is widely supported and adopted and gives at least 30% better than current generation video codecs.

• Private by Design: How we built Firefox Sync

  Firefox Sync lets you share your bookmarks, browsing history, passwords and other browser data between different devices, and send tabs from one device to another. It’s a feature that millions of our users take advantage of to streamline their lives and how they interact with the web.

  But on an Internet where sharing your data with a provider is the norm, we think it’s important to highlight the privacy aspects of Firefox Sync.

  Firefox Sync by default protects all your synced data so Mozilla can’t read it. We built Sync this way because we put user privacy first. In this post, we take a closer look at some of the technical design choices we made and why.

• The Ceph Foundation has been launched by the Linux Foundation to support the open source storage project

• Linux Foundation Launches Open Source Ceph Storage Group

  Open source storage gets a boost today as the Linux Foundation launches the Ceph Foundation with more than 30 members including China Mobile, DigitalOcean, Intel, OVH, and Red Hat.

  The Ceph project is a unified distributed storage system providing applications with object, block, and file system interfaces. It was co-founded more than a decade ago by Sage Weil, who is now chief architect at Red Hat for Ceph, and University of California, Santa Cruz professor Carlos Maltzahn. A whole team of storage engineers now manage and maintain the open source code.

• OPNFV Gambia — Doing what we do best while advancing cloud native

  Today, the OPNFV community is pleased to announce the availability of Gambia, our seventh platform release! I am extremely proud of the way the community rallied together to make this happen and provide the industry with another integrated reference platform for accelerating their NFV deployments.

  At a high level, Gambia represents our first step towards continuous delivery (CD) and deepens our work in cloud native, while also advancing our core capabilities in testing and integration, and the development of carrier-grade features by working upstream. As an open source pioneer in NFV, it’s amazing to see the evolution of the project to meet the needs of a quickly changing technology landscape.

• Rugged, low-cost Bay Trail SBC runs Linux

  VersaLogic released a rugged, PC/104-Plus form-factor “SandCat” SBC with a dual-core Intel Bay Trail SoC, -40 to 85℃ support, plus SATA, GbE, and mini-PCIe and more, starting at $370 in volume.

  VersaLogic has spun a simpler, more affordable alternative to its BayCat single board computer, which similarly offers a Linux supported Intel Bay Trail SoC in a PC/104-Plus form-factor board. The rugged new SandCat is limited to a dual-core, 1.33GHz Atom E3825, and offers a somewhat reduced feature set, but launches at less than half the price of the dual-core version of the BayCat, selling at $370 in volume.

• HelpSystems Gets Into JAMS for Scheduling

  HelpSystems yesterday announced the acquisition of MVP Systems Software, the Connecticut-based developer of the JAMS workload management and scheduling software. While JAMS supported IBM i, HelpSystems will count on the product to deliver capabilities primarily in the open systems realm, with cloud possibilities looming in the future.

  The acquisition came together as the result of mutual respect that HelpSystems and MVP Systems Software had for each other, says Kate Bolseth, general manager of cross platform products at HelpSystems.

• What's the reality of OpenStack and public cloud?

  My colleague, Margaret Dawson, spends a lot of time talking with customers. And in those conversations, questions about cloud and OpenStack invariably come up. She shared this message a while back, during her keynote at the OpenStack Summit in Vancouver, and it still resonates. While public cloud looms large in many companies’ plans, OpenStack’s future looks bright in the hybrid cloud reality we see today -- and tomorrow.

  “Most of you, especially if you’ve been working on OpenStack for a while, hear ‘Game’s over. Why are we even still doing this? AWS has won, so let’s just put everything in the public cloud and call it a day.”

• Impact of IBM-Red Hat Merger

  Recently, there have been numerous machine learning, and AI algorithms developed to achieve the desired output in a dynamic, efficient, and effective manner. However, in a real-time scenario, an individual algorithm has its own advantages and is restricted to certain limitations. These limitations can be minimized by integrating different algorithms to achieve the desired task. By capturing the insights into the integral approach, IBM has announced its acquisition of Red Hat technologies to enhance its cloud-based business services to its clients.

  In the past year, nearly a quarter of IBM overall revenue was achieved through the cloud service platform. But with an increase in competitors, the company was overshadowed by other cloud rivals such as Microsoft and Amazon. Ginni Rometty, CEO of IBM, stated that at present, only 20 percent of the companies are renting cloud services to cut costs; over 80 percent are still unlocking their business values and can shift their business applications to the hybrid cloud in the near future for data extraction and optimization.

Debian packages have supported the concept of vendor-specific patches whereby when DPKG unpacks a source package on different operating systems / distributions (such as Debian vs. Ubuntu), different patches could be selectively applied. Ubuntu is one of the main benefactors of this feature while effective immediately these vendor-specific patches to source packages will be treated as a bug and will be unpermitted following the Debian 10 "Buster" release.

This vendor-specific patch behavior for DPKG is mainly to help downstreams of Debian such as Ubuntu (not to be confused with vendor-specific hardware patches, etc). This vendor-specific patching has been used where say Ubuntu wishes to make some customizations to a Debian package that are minor in nature or basic alterations, they could land the changes in upstream Debian as a vendor-specific patch that would then be applied to the source package when building on Ubuntu... But keeping the package unpatched on Debian, or vice-versa. It reduces the maintenance burden for those wanting to selectively make basic changes to a package without having to maintain multiple largely redundant packages.

A couple of weeks ago IBM announced its plan to buy Red Hat for $34 billion. Following that, experts started speculating that rival companies like Canonical and Suse would sell as well.

However, Canonical’s founder, Mark Shuttleworth, doesn’t seem to have any plans of selling the company — at least not in the near future. In an encounter with TechCrunch, he said, “I value my independence.”

One of the reasons behind this decision is that he doesn’t really need the money. But another big reason for not selling is his vision for Canonical and Ubuntu, which he would like to see through personally.

Raven, the Super+A menu, is the special right panel on Budgie Desktop Environment. It's represented by a white door icon with a left arrow on it beside the power icon on the top panel. It's interesting as it's fun to show/hide in end-user's perspective. It's unique, compared to same right-side panel concepts on BlankOn and deepin, it has own name Raven while being very minimal yet usable. See more below. This is the continuation after the first part talked about the Top Panel. Enjoy and please wait the next part about Applets!

Ubuntu 19.04 "Disco Dingo" development is now officially underway.

Following the initial sync from Debian unstable, Ubuntu developer Matthias Klose announced this morning that "Disco Dingo is now open for development."

The initial prominent changes in the archive include landing Python 3.7 as the default Python3 version after Ubuntu 18.10 shipped with Python 3.6, removal of OpenSSL 1.0 with intending to only ship OpenSSL 1.1.1 LTS, and upgrading to Perl 5.28.
