The Clinical Trial Technical Challenge: Programmability and Extensibility at Scale

Aggregated on: Wed Dec 29 2021 16:34:28 GMT+0000 (Coordinated Universal Time)

Clinical trials are an extraordinarily complex and vitally important undertaking. These are enormous projects, with the cost of developing a single new drug averaging $2.6 billion. A phase-3 clinical trial — the final stage before approval — will involve thousands, sometimes tens of thousands, of participants. Hundreds, even thousands, of data points for each participant must be tracked over time for years. Ultimately, this means there could be hundreds of millions of data points that must be protected, secured and blinded. And, ultimately, all of that data will need to pass through multiple different applications for analysis. Don’t be fooled by the extraordinarily fast pace of COVID-19 vaccine development. This is not the norm. These clinical trials were conducted safely and rigorously, but they also had unprecedented resources and the urgent need for a vaccine to combat a deadly, highly infectious disease pushing them forward. Most clinical trials take six to seven years to complete. Given the stakes — these new treatments could save and vastly improve the quality of life for millions of people — if there’s a way to speed up the process without compromising the science or ballooning budgets to the size required to combat an urgent global crisis, shouldn’t we do so?

Aggregated on: Wed Dec 29 2021 13:04:28 GMT+0000 (Coordinated Universal Time)

How Different Tech Stacks Compare After deploying countless websites, you will see the narrow difference between tech stacks. Python, PHP, JavaScript, Elixir, Ruby, and others all write HTTP responses. This uniformity means developers can pass all HTTP handling through a standardized webserver interface like Apache/NGINX. Web servers are a MUST and highly optimized for driving web traffic. Apache/NGINX fulfill common needs such as simultaneous requests, encryption, and "path rewriting" (sales). Businesses that do not use quintessential web servers are doomed to face early scaling issues.

Avoid Yoda Conditions in Perl You Should

Aggregated on: Tue Dec 28 2021 20:49:27 GMT+0000 (Coordinated Universal Time)

I remember a brief time in the mid-2000s insisting on so-called “Yoda conditions” in my Perl. I would place constants to the left of equality comparisons. In case I accidentally typed a single = instead of ==, the compiler would catch it instead of blithely assigning a variable. For example: Perl if ( $foo == 42 ) { ... } # don’t do this if ( 42 == $foo ) { ... } # do this if ( $foo = 42 ) { ... } # to prevent this And, because a foolish consistency is the hobgoblin of little minds, I would even extend this to string and relational comparisons.

NullPointerException: the Most Common Exception NullPointerException (NPE) is the most common exception in Java. The cause of this exception is known but looks like that in most cases developers prefer to ignore it and don't take any action. I personally expect that reasons for such behavior are the following: Most of the developers don't see any problem here and recognize all NPE exceptions as the developer's fault. Developers who are aware of this design problem don't know how to fix it. In this article, I'll explain what is the root of this problem and provide ways to fix that problem.

Systematic and Chaotic Testing: A Way to Achieve Cloud Resilience

Aggregated on: Mon Dec 27 2021 16:34:26 GMT+0000 (Coordinated Universal Time)

In today’s digital technology era where downtime translates to shut down, it is imperative to build resilient cloud structures. For example, in the pandemic, IT maintenance teams can no longer be on-premises to reboot any server in the data center. This may lead to a big hindrance in accessing all the data or software, putting a halt on productivity, and creating overall business loss if the on-premises hardware is down. However, the solution here would be to transmit all your IT operations to cloud infrastructure that ensures security by rendering 24/7, round-the-clock tech support by remote members. Cloud essentially poses as a savior here. Recently, companies have been fully utilizing the cloud potency, and hence, observability and resilience of cloud operations become imperative as downtime now equates to disconnection and business loss.

Introduction Data security is an important aspect of the digital world. It helps to prevent data breaches, reduces the risk of data exposure, secures sensitive data, and is highly recommended for the regulatory compliance process. Within any organization, data security's role is to ensure the safety and security of private and commercial/finance data while minimizing exposure risk. PGP (Pretty Good Privacy) is an encryption program that is used to encrypt and decrypt texts, files, e-mails, and directories. Many applications within an organization use CSV files to transfer huge data from one system to another. Securing this data while in transit is a key factor during data transmission. This blog will help you provide a step-by-step procedure to encrypt and decrypt a CSV file at source and destination. We will encrypt and decrypt the following contents of a CSV file.

Create an Azure Blob Storage Account and Upload a File

Aggregated on: Mon Dec 27 2021 02:49:26 GMT+0000 (Coordinated Universal Time)

Introduction Storage accounts are one of the fundamental pieces of cloud technology. They contain all of our Azure Storage data objects: blobs, files, queues, tables, and disks. Microsoft offers several options to store data on the cloud. Storage can be used for two purposes: One is to actually store files, just as we do on a hard disk. The other is to use it as the backend of a Virtual Machine. Many services within Azure need a storage account, sometimes for logging and sometimes as a fundamental piece of the technology. By default, Virtual Machines run on a managed storage account, which is an abstraction on top of a storage account. We cannot use it to create a Virtual Machine on top of an unmanaged account. In this article, we will look at how to create an Azure blob storage account and upload a file on the blob.

How To Connect Stateful Workloads Across Kubernetes Clusters

Aggregated on: Fri Dec 24 2021 12:49:25 GMT+0000 (Coordinated Universal Time)

One of the biggest selling points of Apache Cassandra™ is its shared-nothing architecture, making it an ideal choice for deployments that span multiple physical data centers. So when our Cassandra as-a-service single-region offering reached maturity, we naturally started looking into offering it cross-region and cross-cloud. One of the biggest challenges in providing a solution that spans multiple regions and clouds is correctly configuring the network so that Cassandra nodes in different data centers can communicate with each other successfully, even as individual nodes are added, replaced, or removed. From the start of the cloud journey at DataStax, we selected Kubernetes as our orchestration platform, so our search for a networking solution started there. While we’ve benefited immensely from the ecosystem and have our share of war stories, this time we chose to forge our own path, landing on ad-hoc overlay virtual application networks (how’s that for a buzzword soup?). In this post, we’ll go over how we arrived at our solution, its technical overview, and a hands-on example with the Cassandra operator.
