Using your devices as the key to your apps

I keep a very detailed budget. I have for the last 7 years. I manually input every expense into a spreadsheet app and use a combination of sumifs functions to track spending.

Opening the spreadsheet app, and then the specific spreadsheet, every time that I want to submit an expense is a little clunky. I'm working on a new project to make that easier. I'm building a simple web app, with a very basic form, into which I will enter one-off expenses. This form will then append those expenses as rows into the budget workbook.

I want to lock down this project; I prefer that I am the only person with the power to wreck my budget. To do that, I'm going to use Cloudflare Access. With Access, I can require a login to reach the page - no server-side changes required.

Except, I don't want to allow logins from any device. For this project, I want to turn my iPhone into the only device that can reach this app.

To do that, I'll use Cloudflare Access in combination with an open source toolkit from Cloudflare, cfssl. Together, I can convert my device into a secure key for this application Continue reading

Heavy Networking 503: Achieve Multi-Domain Network Automation With Itential (Sponsored)

On today’s Heavy Networking, we talk with sponsor Itential about its network automation approach, where you can take what you’re already using (scripts, Ansible, etc.) and incorporate it into a holistic automation strategy. Itential enables automation across physical, virtual, and cloud domains and takes a low-code approach so that your engineers don’t have to become developers. Our guest is Chris Wade, Itential's co-founder and CTO.

IDC: Chinese server sales will take a hit due to coronavirus

With virtually all of China shutdown and under quarantine due to the coronavirus, the Chinese IT hardware market will suffer a temporary but significant impact in the first quarter due to demand not being met. While foreign impact is not certain, it does have the potential to spill over into other markets.IDC now predicts the total 2020 server growth rate will be reduced from original growth projections of 12.4% to 7.4%, and Q1 sales will drop 15% from the same time period last year instead of the original projection of 16.5% growth.[Get regularly scheduled insights by signing up for Network World newsletters.] Storage 2020 growth rate will be reduced from 12.5% to 7.3% and Q1 will be down 20% instead of the original projection of 16.6% growth over Q1 2019. The 2020 networking growth rate has been reduced from the original 6.2% to 3.0%.To read this article in full, please click here

Google Cloud moves to aid mainframe migration

Google Cloud this week bought a mainframe cloud-migration service firm Cornerstone Technology with an eye toward helping Big Iron customers move workloads to the private and public cloud. Google said the Cornerstone technology – found in its G4 platform – will shape the foundation of its future mainframe-to-Google Cloud offerings and help mainframe customers modernize applications and infrastructure.[Get regularly scheduled insights by signing up for Network World newsletters.] “Through the use of automated processes, Cornerstone’s tools can break down your Cobol, PL/1, or Assembler programs into services and then make them cloud native, such as within a managed, containerized environment” wrote Howard Weale, Google’s director, Transformation Practice, in a blog about the buy.To read this article in full, please click here

Japanese firm announces potential 80TB hard drives

Hard drive makers are staving off obsolescence to solid-state drives (SSDs) by offering capacities that are simply not feasible in an SSD. Seagate and Western Digital are both pushing to release 20TB hard disks in the next few years. A 20TB SSD might be doable but also cost more than a new car.But Showa Denko K.K. of Japan has gone one further with the announcement of its next-generation of heat-assisted magnetic recording (HAMR) media for hard drives. The platters use all-new magnetic thin films to maximize their data density, with the goal of eventually enabling 70TB to 80TB hard drives in a 3.5-inch form factor.[Get regularly scheduled insights by signing up for Network World newsletters.] Showa Denko is the world’s largest independent maker of platters for hard drives, selling them to basically anyone left making hard drives not named Seagate and Western Digital. Those two make their own platters and are working on their own next-generation drives for release in the coming years.While similar in concept, Seagate and Western Digital have chosen different solutions to the same problem. HAMR, championed by Seagate and Showa, works by temporarily heating the disk material during the write Continue reading

What Is Closed-Loop Automation?

During Networking Field Day 22 last week, a lot the questions that were directed at the presenters had to do with their automation systems. One term kept coming up that I was embarrassed to admit that I’d never heard of. Closed-loop automation is the end goal for these systems. But what is closed-loop automation? And why is it so important. I decided to do a little research and find out.

Open Up

To understand closed-loop systems, you have to understand open-loop systems first. Thankfully, those are really simple. Open-loop systems are those where the output isn’t directly affected by the control actions of the system. It’s a system where you’re going to get the output no matter how you control it. The easiest example is a clothes dryer. There are a multitude of settings that you can choose for a clothes dryer, including the timing of the cycle. But no matter what, the dryer will stop at the end of the cycle. There’s no sensor in a basic clothes dryer that senses the moisture level of the clothes and acts accordingly.

Open-loop systems are stable and consistent. Every time you turn on the dryer, it will run until it finishes. Continue reading
