LSM-trees are widely adopted as the storage backend of key-value stores. However, optimizing the system performance under dynamic workloads has not been sufficiently studied or evaluated in previous work. To fill the gap, we present RusKey, a key-value store with the following new features: (1) RusKey is a first attempt to orchestrate LSM-tree structures online to enable robust performance under the context of dynamic workloads; (2) RusKey is the first study to use Reinforcement Learning (RL) to guide LSM-tree transformations; (3) RusKey includes a new LSM-tree design, named FLSM-tree, for an efficient transition between different compaction policies -- the bottleneck of dynamic key-value stores. We justify the superiority of the new design with theoretical analysis; (4) RusKey requires no prior workload knowledge for system adjustment, in contrast to state-of-the-art techniques. Experiments show that RusKey exhibits strong performance robustness in diverse workloads, achieving up to 4x better end-to-end performance than the RocksDB system under various settings.

Back in 2019, I wrote about the "container tax." In simple terms, this is the additional cost to use containers properly within a cloud-based application. It includes development, operations, and other expenses that containers incur. The goal of leveraging containers is to offset the additional costs with the benefits they offer. Many other technologies come with additional costs, which may or may not justify using that specific technology.

Only weeks after a Southwest Airlines meltdown led to thousands of canceled flights and stranded passengers, the nation's air travel system was briefly interrupted Wednesday due to an outage in the computer system used by the Federal Aviation Administration to give pilots vital information before they take off. While the FAA system was back online within hours and flights were slowly returning to schedule, those passengers whose lives were upended in last month's Southwest debacle are still feeling the effects of the meltdown and tallying up the financial damage they endured. Passengers who spoke to The Times said the fiasco cost them between $700 in one instance (for gas costs) and $70,000 in another (for a destination wedding that was ruined). "I am trying to be patient and give them a chance to make things right," said one of Southwest's stranded passengers, actor Deborah Rombaut. "What bothers me is that I don't have a timeline as far as when I'll be reimbursed." Thousands of holiday travelers like Rombaut were stranded late last month when Southwest Airlines said its computer system that tracked crew scheduling could not keep up with a severe winter storm.

Box, Inc. the leading Content Cloud, today unveiled Box Canvas, virtual whiteboarding and visual collaboration experience that securely connects hybrid teams so they can brainstorm, ideate, and create, together from anywhere. Built natively into Box, and available later this year to all users at no additional cost, Box Canvas will deliver a powerful new way for people to collaborate, while leveraging the enterprise-grade security, compliance, and workflow automation capabilities Box's 100,000 customers know and love. Box Canvas will be introduced at the Box Content Cloud Summit on Thursday, April 14. "With approximately 70 percent of companies in the U.S. and Europe planning to establish a hybrid work environment, it's clear that the future of work is here," said Diego Dugatkin, Chief Product Officer at Box. "This new way of working requires tools that extend beyond static document types and traditional communication styles to be more dynamic and fluid. Box is taking collaboration to the next level with Box Canvas. Our goal is to unleash the power of creativity so teams can solve complex problems, nurture fresh ideas, and create new ways of working together from anywhere."

AWS(Amazon Web Services) is the most popular and widely used cloud service provider. In 2017 AWS released its fully managed machine learning platform on cloud called Amazon Sagemaker, that allows developers to create, train and deploy their models quickly. In 2018, Amazon Sagemaker Ground Truth was launched to fully manage data labelling services for generating high-quality ground truth datasets to be trained into machine learning models. Ground Truth can integrate Amazon Mechanical Turk(the crowdsourcing platform) or internal data labelling team or external 3rd party vendors to get the labelling job done. Workflows can be customized or made use of built-in.

If a woman (or non-female identifying person with a uterus and visions of starting a family) is struggling to conceive and decides to improve their reproductive odds at an IVF clinic, they'll likely interact with a doctor, a nurse, and a receptionist. They will probably never meet the army of trained embryologists working behind closed lab doors to collect eggs, fertilize them, and develop the embryos bound for implantation. One of embryologists' more time-consuming jobs is doing something called "grading" embryos--looking at their morphological features under a microscope and assigning a quality score. Round, even numbers of cells are good. They'll use that information to decide which embryos to implant first. Newer methods, like pulling off a cell to extract its DNA and test for abnormalities, something called preimplantation genetic screening, provide more information.

In 2016, an estimated 65.6 million people across the globe were forced from their homes by everything from war to human rights violations. Climate change and global warming are exacerbating the problem of displaced persons, with millions of people expected to be forced to relocate to other -- often cooler -- countries. The problem is becoming so widespread that New Zealand is even considering creating a new visa specifically for those displaced by climate change. Once they make the difficult decision to leave their home, refugees face a slew of other questions: To which country do they flee? Where in that country should they go?
