Red Hat and SUSE have withdrawn their support for OpenLDAP in their Enterprise Linux offers, which will be replaced by Red Hat’s own 389 Directory Server. The openldap-server packages were deprecated starting from Red Hat Enterprise Linux (RHEL) 7.4, and will not be included in any future major release of RHEL. SUSE, in their release notes, have mentioned that the OpenLDAP server is still available on the Legacy Module for migration purposes, but it will not be maintained for the entire SUSE Linux Enterprise Server (SLE) 15 lifecycle. What is OpenLDAP? OpenLDAP is an open source implementation of Lightweight Directory Access Protocol (LDAP) developed by the OpenLDAP Project. It is a collective effort to develop a LDAP suite of applications and development tools, which are robust, commercial-grade, and open source. What is 389 Directory Server? The 389 Directory Server is an LDAP server developed by Red Hat as a part of Red Hat’s community-supported Fedora Project. The name “389” comes from the port number used by LDAP. It supports many operating systems including Fedora, Red Hat Enterprise Linux 3 and above, Debian, Solaris 8 and above. The 389 Directory Server packages provide the core directory services components for Identity Management (IdM) in Red Hat Enterprise Linux and the Red Hat Directory Server (RHDS). The package is not supported as a stand-alone solution to provide LDAP services. Why Red Hat and SUSE withdrew their support? According to Red Hat, customers prefer Identity Management (IdM) in Red Hat Enterprise Linux solution over OpenLDAP server for enterprise use cases. This is why, they decided to focus on the technologies that Red Hat historically had deep understanding, and expertise in, and have been investing into, for more than a decade. By focusing on Red Hat Directory Server and IdM offerings, Red Hat will be able to better serve their customers of those solutions and increase the value of subscription. To know more on Red Hat and SUSE withdrawing their support for OpenLDAP, check out Red Hat’s announcement and SUSE release notes.

IBM with its partners, Rocket Software and CA Technologies, have announced the launch of Zowe at the ongoing Open Source Summit in Vancouver, Canada. It is the first z/OS open source project, which is part of the Linux Foundation’s Open Mainframe Project community. Why is Zowe introduced? The rapid technology advancements and rising expectations in user experience demands  more productive and better integrated capabilities for z/OS, an operating system for IBM mainframes. Zowe enables delivery of such an environment through an extensible open source framework. It aims to create an ecosystem of Independent Software Vendors (ISVs), System Integrators, clients, and end users. By using it, development and operations teams can securely manage, control, script and develop on the mainframe like any other cloud platform. What are its components? The four main components of Zowe are: the Explorer server, API Mediation Layer, zLUX, and Zowe CLI. Source: Zowe Zowe APIs and Explorers z/OS Management Facility (z/OSMF) supports the use of REST APIs, which are public APIs that your application can use to work with system resources and can also extract system data. With the help of these REST APIs, Zowe submits jobs, works with the Job Entry Subsystem (JES) queue, and manipulates UNIX System Services (USS) or Multiple Virtual Storage (MVS) datasets. Explorers are visual representations of these APIs that are wrapped in the Zowe web UI application. They create an extensible z/OS framework that provides new z/OS REST services to transform enterprise tools and DevOps processes to incorporate new technology, languages, and modern workflows. Zowe API Mediation Layer The following are the key components of API Mediation Layer: API Gateway: It is built using Netflix Zuul and Spring Boot technology. Its purpose is to forward API requests to the appropriate corresponding service through the microservice endpoint UI. Discovery Service: It is built on Eureka and Spring Boot technology. It acts as the central point in the API Gateway that accepts announcements of REST services, and is a repository for active services. API Catalog: It is used to view the services running in API Mediation Layer. You can also view the corresponding API documentation to a service. Zowe Web UI Web UI named zLUX, modernizes and simplifies working on the mainframe.The UI works with the underlying REST APIs for data, jobs, and subsystems, and presents the information in a full-screen mode. It gives users a unifying experience where various applications can work together. Zowe Command Line Interface (CLI) Zowe CLI is used to allow user interactions from different platforms with z/OS. The platforms which can be cloud or distributed systems are able to submit jobs, issue TSO and z/OS console commands, integrate z/OS actions into scripts, and produce responses as JSON documents with the help of Zowe CLI. Currently, the Zowe is available in beta and is not intended for production use. The Zowe Leadership Committee is targeting to have a stable release by the end of the year. To know more about the launch of Zowe, refer to IBM’s announcement on their official website.

The Bodhi Team have announced the fifth major release of their Linux distribution. Bodhi Linux 5.0.0 comes with an updated Ubuntu core 18.04 and an overall modern look for its Moksha Window Manager. Bodhi Linux was first released as a stable version seven years ago, as a lightweight Linux distribution based on Ubuntu and Moksha window manager. It uses a minimal base system allowing users to populate it with the software of their choice. Bodhi Linux 5.0.0 features disc images which have a fresh new look; a modified version of the popular 'Arc Dark' theme colorized in Bodhi Green. They have also included a fresh default wallpaper, login screen, and splash scenes as your system boots. Bodhi Linux Default Desktop - Busy Bodhi Linux Desktop - Clean The Bodhi team have not provided a change log because the move to an Ubuntu 18.04 base from 16.04 is the only major difference. Ubuntu 18.04 comes with changes such as Better metric collection in Ubuntu Report Support for installing on NVMe with RAID1 Fix for a typo that made update-manager report crash Miscellaneous unattended-upgrade fixes Ubuntu welcome tool now mentions dock and notifications Patches to make audio work on Lenovo machines with dual audio codecs Restore New Tab menu item in GNOME Terminal New “Thunderbolt” panel in Settings app If you installed a pre-release of Bodhi 5.0.0 you will simply need to run your system updates for the latest ISO images. However, the system updates will not adjust the look of your desktop automatically. If you have a previous Bodhi release installed you will need to do a clean install to upgrade to Bodhi 5.0.0. Bodhi 4.5.0 will have support until Ubuntu 16.04 runs out in April 2021. You can read more about the Bodhi 5.0.0 release on Bodhi Linux Blog. What to expect from upcoming Ubuntu 18.04 release. Is Linux hard to learn? Red Hat Enterprise Linux 7.5 (RHEL 7.5) now generally available.

Google Cloud Next conference in San Francisco in July 2018 saw some exciting new developments in the field of serverless technology. The company is giving development teams the ability to build apps without worrying about managing servers with their new serverless technology. Bringing the best of both worlds: Serverless and containers, Google announced that Cloud Functions is now generally available and ready for production use. Here is a list of the all-new features that developers can watch out for- #1 Write Cloud Functions using  Node 8, Python 3.7 With support for async/await and a new function signature, you can now write Cloud Functions using Node 8. Dealing with multiple asynchronous operations is now easier thanks to Cloud Functions that provide data and context. You can use the await keyword to await the results of asynchronous operations. Python 3.7 can also be used to write Cloud Functions.  Similar to Node, you get data and context for background functions, and request for HTTP. Python HTTP functions are based on the popular Flask microframework. Flask allows you to get set up really fast. The requests are based on flask.Request and the responses just need to be compatible with flask.make_response. As with Node, you get data (dict) with Python background functions and context (google.cloud.functions.Context). To signal completion, you just need to return from your function or raise an exception and Stackdriver error handling will kick in. And, similarly to Node (package.json), Cloud Functions will automatically do the installation of all of your Python dependencies (requirements.txt) and build in the cloud. You can have a look at the code differences between Node 6 and Node 8 behavior and at a Flask request on the Google Cloud website. #2 Cloud Functions is now out  for Firebase Cloud Functions for Firebase is also generally available. It has full support for Node 8, including ECMAScript 2017 and async/await. The additional granular controls include support  for runtime configuration options, including region, memory, and timeout. Thus allowing you to refine the behavior of your applications. You can find more details from the Firebase documentation. Flexibility for the application stack now stands improved. Firebase events (Analytics, Firestore, Realtime Database, Authentication) are directly available in the Cloud Functions Console on GCP. You can now trigger your functions in response to the Firebase events directly from your GCP project. #3 Run headless Chrome by accessing system libraries Google Cloud functions have also broadened the scope of libraries available by rebasing the underlying Cloud Functions operating system onto Ubuntu 18.04 LTS. Access to system libraries such as ffmpeg and libcairo2 is now available- in addition to imagemagick- as well as everything required to run headless Chrome. For example, you can now process videos and take web page screenshots in Chrome from within Cloud Functions. #4 Set environment variables You can now pass configuration to your functions by specifying key-value pairs that are bound to a function. The catch being, these pairs don’t have to exist in your source code. Environment variables are set at the deploy time using the --set-env-vars argument. These are then injected into the environment during execution time. You can find more details on the Google cloud webpage. #5 Cloud SQL direct connect Now connect Cloud Functions to Cloud SQL instances through a fully managed secure direct connection.  Explore more from the official documentation. What to expect next in Google Cloud Functions? Apart from these, Google also promises a range of features to be released in the future. These include: 1. Scaling controls This will be used to limit the number of instances on a per-function basis thus limiting traffic. Sudden traffic surge scenarios will , therefore,come under control when Cloud Functions rapidly scales up and overloads a database or general prioritization based on the importance of various parts of your system. 2. Serverless scheduling You’ll be able to schedule Cloud Functions down to one-minute intervals invoked via HTTP(S) or Pub/Sub. This allows you to execute Cloud Functions on a repeating schedule. Tasks like daily report generation or regularly processing dead letter queues will now pick up speed! 3. Compute Engine VM Access Now connect to Compute Engine VMs running on a private network using --connected-vpc option. This provides a direct connection to compute resources on an internal IP address range. 4. IAM Security Control The new Cloud Functions Invoker IAM role allows you to add IAM security to this URL. You can control who can invoke the function using the same security controls as used in Cloud Platform 5. Serverless containers With serverless containers, Google provides the same infrastructure that powers Cloud Functions. Users will now be able to simply provide a Docker image as input. This will allow them to deploy arbitrary runtimes and arbitrary system libraries on arbitrary Linux distributions This will be done while still retaining the same serverless characteristics as Cloud Functions. You can find detailed information about the updated services on Google Cloud’s Official page. Google Cloud Next: Fei-Fei Li reveals new AI tools for developers Google Cloud Launches Blockchain Toolkit to help developers build apps easily Zeit releases Serverless Docker in beta

Zeit, the organization behind the cloud deployment software Now, yesterday launched Serverless Docker in beta. The concept was first discussed by the Zeit team at Zeit Day 2018 back in April, but it's now available to use and promises to radically speed up deployments for engineers. In a post published on the Zeit website yesterday, the team listed some of the key features of this new capability, including: An impressive 10x-20x improvement in cold boot performance (in practice this means cold boots can happen in less than a second A new slot configuration property that defines resource allocation in terms of CPU and Memory, allowing you to fit an application within the set of constraints that are most appropriate for it Support for HTTP/2.0 and WebSocket connections to deployments, which means you no longer need to rewrite applications as functions. The key point to remember with this release, according to Zeit, is that  "Serverless can be a very general computing model. One that does not require new protocols, new APIs and can support every programming language and framework without large rewrites." Read next: Modern Cloud Native architectures: Microservices, Containers, and Serverless – Part 1 What's so great about Serverless Docker? Clearly, speed is one of the most exciting things about serverless Docker. But there's more to it than that - it also offers a great developer experience. Johannes Schickling, co-founder and CEO of Prisma (a GraphQL data abstraction layer) said that, with Serverless Docker, Zeit "is making compute more accessible. Serverless Docker is exactly the abstraction I want for applications." https://twitter.com/schickling/status/1029372602178039810 Others on Twitter were also complimentary about Serverless Docker's developer experience - with one person comparing it favourably with AWS - "their developer experience just makes me SO MAD at AWS in comparison." https://twitter.com/simonw/status/1029452011236777985 Combining serverless and containers One of the reasons people are excited about Zeit's release is that it provides the next step in serverless. But it also brings containers into the picture too. Typically, much of the conversation around software infrastructure over the last year or so has viewed serverless and containers as two options to choose from rather than two things that can be used together. It's worth remembering that Zeit's product has largely been developed alongside its customers that use Now. "This beta contains the lessons and the experiences of a massively distributed and diverse user base, that has completed millions of deployments, over the past two years." Eager to demonstrate how Serverless Docker works for a wide range of use cases, Zeit has put together a long list of examples of Serverless Docker in action on GitHub. You can find them here.

Google Cloud launched new Blockchain tools for developers on Monday, as a result of a collaboration with a DLT (distributed ledger technology) startup to help developers easily build apps. Google seems to take inspiration from AWS. Amazon’s cloud company partnered with Hyperledger Fabric earlier this year, introducing Blockchain templates which, allow developers to launch Ethereum apps without needing to write all the code required to create a smart contract. Digital Asset, a Blockchain platform services run by former JPMorgan executive Blythe Masters, will provide a software development kit to developers working on Google cloud. Along with this, Digital Asset Modeling Language (DAML), a platform-as-a-service (PaaS) program will also be made available to developers. The DAML PaaS program is now available through Google Cloud’s Orbitera Application Marketplace. According to Leonard Law, Head of Financial Services Platform at Google Cloud, “DLT has great potential to benefit customers not just in the financial services industry, but across many industries, and we’re excited to bring these developer tools to Google Cloud.” Blythe Masters, CEO of Digital Asset, also mentioned that the company is partnering with Google Cloud to provide a full stack solution to developers “so they can unleash the potential for web-paced innovation in Blockchain”. This, in turn, will help developers and organizations overcome some of the most common technical barriers to DLT application development today. With the arrival of the new Blockchain toolkit, developers will be able to easily manage the distributed systems for financial applications, games, etc. Oracle makes its Blockchain cloud service generally available Blockchain can solve tech’s trust issues – Imran Bashir  

Microsoft keeps rolling out with updates. After Windows 10 SDK Preview Build 17115 which included Machine learning APIs, Microsoft has now released Windows 10 SDK Preview Build 17704, two days ago.

In case you want to download the latest Windows 10 SDK Preview Build 17704, visit the developer section on Windows Insider. Key Updates Here’s what’s new in this latest SDK preview Build: MSIX Support Windows 10 SDK Preview Build 17704 has finally got MSIX support enabled. You can install and run these apps with MSIX support on devices having 17682 build or greater. Using the MakeAppx tool, you can package your applications with MSIX. Just click on the MSIX file to install the application. If you wish to know more about MSIX, check out the video below: https://www.youtube.com/watch?v=FKCX4Rzfysk Source: Microsoft Developer  MC.EXE Changes are made to the C/C++ETW code generation of mc.exe which is a message compiler. “-mof” parameter has been deprecated. The “-mof” parameter instructs MC.exe to generate the ETW code which is compatible with Windows XP and earlier. If “-mof” parameter is not used, the generated C/C++ header is compatible with both kernel-mode and user-mode, regardless of whether “-km” or “-um” was specified on the command line. The generated header supports several customization macros. If you need the generated macros to call something other than EventWriteTransfer, you can set the MCGEN_EVENTWRITETRANSFER macro. The manifest supports new attributes such as Event “names”, event “attributes”, event “tags”, etc. The “provider traits” can be now defined in the manifest (e.g. provider group). The EventRegister[ProviderName] macro will automatically register the provider traits, if they are used in the manifest. MC has the capability to generate Unicode (utf-8 or utf-16) output MC now with the “-cp utf-8” or “-cp utf-16” parameters. API Spot Light There is a new LauncherOptions.GroupingPreference property in the Windows 10 SDK  Preview Build 17704. This helps assist your app in tailoring its behavior for Sets. Apart from these changes in the release, APIs have also been updated, added, and removed. More information about other known issues and improvements is available on the Windows Blog. Microsoft releases Windows 10 Insider build 17682! Microsoft Cloud Services get GDPR Enhancements  

Microsoft announced today that they are releasing Windows 10 Insider build 17682 from the RS5 branch today. The new release includes sets improvements, wireless projection experience, Microsoft Edge improvements, and RSAT along with other updates and fixes. Major improvements and updates Sets Improvements New tab page has been updated which makes it easy to launch apps. On clicking the plus button in a Sets window, apps are visible in the frequent destinations list. The all apps list have been integrated into the new tab page to make it easy to browse apps instead of using the search box. Apps supporting Sets when clicked will launch into a new tab. In case you select News Feed, just select the “Apps” link which is next to “News Feed”, this will help switch to the all apps list. Managing Wireless Projection Experience Earlier, there were disturbances during wireless projection for users when the session was started through file explorer or an app. This has been fixed now with Windows 10 Insider build 17682 as there’ll be a control banner at the top of a screen during a session. The control banner informs you about your connection state, lets you tune the connection as well as helps with quick disconnect or reconnect to the same sink. Tuning is done with the help of settings gear. Screen to screen latency is optimized based on the following scenarios: Game mode makes gaming over a wireless connection possible by minimizing screen to screen latency. Video mode ensures smooth playback of the videos without any glitches on the big screen by increasing screen to screen latency. Productivity mode helps to balance between game mode and video mode. Screen to screen latency is responsive enough so that typing feels natural while ensuring limited glitch in the videos. All connections start off in the productivity mode. Improvements in Microsoft Edge for developers With the latest Windows 10 insider build 17682, there is unprefixed support for the new Web Authentication API (WebAuthN). Web Authentication helps provide a scalable and interoperable solution. It helps with replacing passwords with stronger hardware-bound credentials. Microsoft Edge users can use Windows Hello (via PIN or biometrics). They can also use other external authenticators namely FIDO2 Security Keys or FIDO U2F Security Keys. This helps authenticate the websites securely. RSAT available on demand No need to manually download RSAT on every upgrade. Select the “Manage Optional features” in Settings. Then click on “Add a feature” option which will provide you with all the listed RSAT components. You can pick the components you want, and on next upgrade, Windows will ensure that all those components automatically persist the upgrade. More information about other known issues and improvements is on the Window’s Blog.

Kali Linux 2018.2 released How to implement In-Memory OLTP on SQL Server in Linux What to expect from upcoming Ubuntu 18.04 release

Ubuntu 18.04 official release is scheduled on April 26th 2018. Ubuntu 17.10 was released in October 2017 and within a span of 6 months, they are releasing their next big update in 18.04. The version numbers of Ubuntu have an interesting trait, where-in 18.04 will be released in the 4th month of 2018, similar to 17.10, which was released in 10th month of 2017. Ubuntu 18.04 comes with some exciting new feature releases: Extending support to color emojis All the previous versions of Ubuntu supported monochrome black and white emojis, which definitely lacked aesthetic appeal. This update might not be at the top of wishlist for anyone using Ubuntu, but emojis form an integral part of modern communication, and also comparing it to other distros like Fedora, which gained color emoji support long back. With 18.04 release, you can add and view color emojis, anytime, anywhere. The release uses Noto Color emoji font, which can be downloaded from the GitHub page. Shipping with Linux Kernel 4.15 Ubuntu 18.04 now ships with the slowest Linux kernel ever since 2011 i.e Kernel 4.15. This brings in much-needed Spectre and Meltdown patch fixes for Ubuntu 18.04. Furthermore, it has also added native-support for Raspberry Pi touchscreen, and has a significant performance boost for AMD GPUs. GNOME 3.28 Unity desktop environment is no longer the default environment anymore, since the release of customized GNOME in Ubuntu 17.10 release. They are planning to continue with it and plotting the latest version of GNOME (3.28) along with 18.04. Xorg display server Wayland was introduced as the default display server for Ubuntu along with the 17.10 release. But it has turned out to be an issue as a decent amount of applications were not supported on Wayland. Hence, in the new release Ubuntu is switching back to Xorg display server as the default option and wayland will be provided as an option to the users. Increase in boot speed Canonical, the company behind Ubuntu, has claimed that Ubuntu 18.04 will have a better boot speed as the systemd’s features will help identifying the bottleneck and solve them as quickly as possible. New installer for the server edition Ubuntu was using their debian text-based installer for their server edition but with the 18.04 release, server edition will be using the all new subiquity installer. Checkout the GitHub page for more about subiquity installer. For minor bug fixes, features and enhancements, refer to the FOSSBYTES blog.

Additionally, we’ve made programming much easier through thread and type safe database APIs, as well as automatic conflict resolution." Key features of Couchbase Mobile 2.0 Here are some of the key features of the Couchbase Mobile 2.0: Full text query and SQL search. Data change events will allow developers to build applications that respond more quickly. That's only going to be good for user experience. Using WebSocket for replication will make replication more efficient. That's because "it eliminates continuously polling servers". Data conflicts can now be resolved much more quickly. This new release will help to cement Couchbase's position as a data platform. And with an impressive list of customers, including Wells Fargo, Tommy Hilfiger, eBay and DreamWorks, it will be interesting to see to what extent it can grow that list. Source: Globe Newswire

There has been a lot of noise around serverless computing over the last couple of years. There have been arguments that it’s going to put the container revolution to bed, and while that’s highly unlikely (containers and serverless are simply different solutions that are appropriate in different contexts), it’s significant that a trend like serverless could emerge so quickly to capture the attention of engineers and architects. It says a lot about the rapidly changing nature of software infrastructures and the increased demands for agility, scalability, and power. Azure is a cloud solution that’s only going to help drive serverless adoption further. But we know there’s always some trepidation among tech decision makers when choosing to implement something new or use a new platform. That’s why we’re delighted to be partnering with Microsoft Azure to give the world free access to Azure Serverless Computing Cookbook. Packed with more than 50 Azure serverless tutorials and recipes to help solve common and not so common challenges, this 325-page eBook is both a useful introduction to Azure’s serverless capabilities and a useful resource for anyone already acquainted with it. Simply click here to go to Microsoft Azure to download the eBook for free.
