The apps included in this roundup are not rated or presented in any quality order.

The artificial intelligence revolution has been going on for a while, but that does not mean all of software research and development is part of it. It is, nonetheless, an interesting example of what pushes the software industry forward. The ideas and techniques that brought machine learning into existence were developed over the span of several decades.

If you need a task manager application to run on your Linux operating system, tap into a software category filled with options that go far beyond the to-do list app you have stuffed into your smartphone. Keeping up to date with multiple daily activity calendars, tons of information, and never-ending must-do lists can become a never-ending challenge.

Salesforce has announced the addition of IoT Insights to Field Service Lightning. The new tool permits signals from IoT devices to show up directly on Salesforce Service Cloud and Field Service Lightning mobile app consoles, alongside CRM data.

Today's Linux platform accommodates a number of really good financial applications that are more than capable of handling both personal and small-business accounting operations. That was not always the case, however. Not quite 10 years ago, I scoured Linux repositories in a quest for replacement applications for popular Microsoft Windows tools. Back then, the pickings were mighty slim.

Amazon recently disclosed its 2015 decision to scrap a recruitment tool used to hire talent, after finding that it had a bias against women. While this story has been covered sufficiently, there is a much greater story still to tell: A substantial amount of the AI technology that currently is used for recruitment and human resources purposes has been acting independently for some time.

For all of the dazzle of its rapidly evolving software portfolio, which includes a self-monitoring and self-patching database that also configures itself, as well as numerous cloud applications, Oracle has begun showing its credibility as a hardware vendor. Hardware has commoditized and will not return to the prominence it had in the early days of the tech era.

The cloud computing landscape may look much different to enterprise users following the announcement earlier this week of IBM's agreement to acquire Red Hat. IBM plans to purchase Red Hat, a major provider of open source cloud software, for $34 billion. IBM will acquire all of the issued and outstanding common shares of Red Hat for $190 per share in cash, under terms of the deal.

Linux apps now can run in a Chromebook's Chrome OS environment. However, the process can be tricky, and it depends on your hardware's design and Google's whims. It is somewhat similar to running Android apps on your Chromebook, but the Linux connection is far less forgiving. If it works in your Chromebook's flavor, though, the computer becomes much more useful with more flexible options.

The Document Foundation has announced the availability of its second major release this year, LibreOffice Fresh 6.1, with enhanced editing on Desktop, Cloud and Mobile platforms.

Anyone who has attempted to adopt Salesforce cloud solutions in an enterprise environment knows that it may not be as easy as expected because of the additional effort typically required to integrate data sources. This is a common problem that has plagued the enterprise application industry since its inception. In fact, it spawned an entire subsegment of integration vendors and service providers.

"Blockchain" is on everyone's lips in the tech industry, with vendors pushing it for everything from banking and finance to retail and apparel. "We're going to continue to see tech vendors trying to push blockchain as the solution to problems that may exist," said Rebecca Wettemann, VP of research at Nucleus Research. However, it may not be "a privacy-effective or cost-effective solution."

Corporate executives know that if they don't transform their companies into digital enterprises they're going to be at a significant competitive disadvantage. Yet many corporate leaders have been unable to make significant progress transforming their organizations. Many executives have found that changing their corporate cultures is a lot harder than adopting cloud-based applications and services.

We often talk about hybrid cloud business models, but virtually always in the context of traditional processor-bound applications. What if deep learning developers and service operators could run their GPU-accelerated model training or inference delivery service anywhere they wanted? What if they could do so without having to worry about which Nvidia graphics processor unit they were using?

IBM has announced IBM Cloud Private, a software platform that allows enterprise customers to run applications and store critical data in an on-premises, private cloud environment.
