1/14/2024 0 Comments Ar turnover formulaOn January 1st, their receivables were $70,000 (beginning accounts receivables). To better explain how the receivable ratio works and how you can find the ratio for your organization, here is an example:Ĭompany XYZ earned $950,000 in net sales over the past 12 months. Indeed, you probably aren’t sure how to calculate the average accounts receivable, let alone the turnover. These operations might seem too confusing when presented as dry formulas like this. Typically, organizations like to calculate the accounts receivable turnover ratio for the past 12 months. The time period you choose to calculate the turnover for is entirely up to you. (Beginning Accounts Receivables + Ending Accounts Receivables) / 2 = Average Accounts Receivable The average accounts receivable is calculated according to this formula: Net Credit Sales / Average Accounts Receivable = Accounts Receivables Turnover The receivables turnover ratio formula is as follows: The accounts receivables turnover is calculated using the account receivables turnover ratio. How to Calculate the Accounts Receivable Turnover? In contrast, a low turnover ratio indicates that the company might have poor credit policies, a bad debt collection method, or that their customers aren’t creditworthy or financially viable. The company’s collection of account receivables is efficient. The turnover ratio is used in accounting to determine the efficiency of a business – it is also called the debtor’s turnover ratio or an efficiency ratio.Ī high turnover ratio typically means that the company has many quality customers who pay their debts in due time. The receivable turnover ratio is a measure derived from the receivables turnover. It is calculated using the accounts receivable turnover ratio. Basically, the receivable turnover reflects how good a company is at collecting payments. Receivable refers to the money owed to the company by its customers or clients. The accounts receivable turnover describes how well a company collects its revenue. These sound like complex terms that you may not have heard of before, but they’re not too difficult to understand once they’re broken down. To know how to use this formula and what it represents, you also need to learn about the accounts receivable turnover (AR turnover) and the accounts receivable turnover ratio (AR turnover ratio). One of the fundamental questions is: what is the accounts receivable turnover formula? However, you should also be familiar with at least the basics of finance & accounting so that you can understand what is happening to your business’ budget. It would be best to hire a professional Finance as a Service partner to handle your finances, especially if you are running a sizable organization. A good finance & accounting operation is at the heart of every successful business. 1/14/2024 0 Comments Macro coteditorA third option would be to install CotEditor with Homebrew.Ĭheck out this article to learn how to install and use Homebrew on your Mac.ĬotEditor is free and open source and requires macOS Monterey or later.

Take it from our customer Ryan Sollmann- we don't just care about making high performance power cables we care about creating custom solutions that meet our customers' needs. If you're in need of a military ac power cord manufacturer, look no further than Almor Power Cables. I would recommend Almor Power Cables to anyone in need of a military grade ac power cord manufacturer, except for my competitors! All jokes aside, sales engineering at Almor Power Cables is as helpful as they are knowledgeable, and I fully trust them to help me help my military customers from here on out. Would you recommend Almor to your colleagues? Because sales engineering at Almor Power Cables proved that he understood and could follow through with a custom military grade ac power cord, I will continue to rely on him to help the customers of Captor Corporation. After two to three months I went back to the Almor team to place an order for my military customer, which was turned around fast and at a fair price point. I received samples within 2-3 business days of our initial conversation, and they were exactly what I was looking for. From his knowledge regarding shielded power cords, to the earnest attitude he conveyed at every stage of our engagement, I knew from day one that Almor was going to be able to help solve my customer's need. One of their engineers recommended that I reach out to Almor Power Cables, and I'm glad I did.Īfter my first call with Almor I was confident that I had found a manufacturer who understood exactly what my military customer needed. How did you arrive at finding Almor Power Cables?Īfter my failed attempts with manufacturers A and B, I wound up going back to my military customer for some guidance. If it weren't for longer lead times on other products that were included in my military customer's configuration, I would probably have lost the sale at this point in time. Looking back, I'm fairly certain that manufacturer B was affiliated with manufacturer A, but I had no way of knowing that ahead of time. Manufacturer B didn't understand my customer's specifications any better than manufacturer A, and they too stopped responding to my outreach after going back and forth with me for a month. I was skeptical when I reached out to manufacturer B, but I kept pushing ahead in order to find someone who could supply my military customer with the proper power cords. But I needed to find my military customer a solution, so I decided to reach out to another manufacturer. After two months of being stuck in an endless communication loop with manufacturer A, I had no choice but to go back to the drawing board. Manufacturer A didn't seem to understand my military customer's application they eventually stopped responding to my calls and emails. I had to send my initial samples back to manufacturer A before they would send me a new prototype, so I had to wait several more days before being able to vet the new sample. The molded ends didn't look right, so I asked them to send me a new prototype. After several days, I received the initial prototype. I reached out to a power cord manufacturing company- we'll call them manufacturer A- who said they could provide me with a sample based on my customer's specifications. Additionally, these cables required very specific molded ends which further complicated my search for a stateside cable manufacturer. I had been working on a project for a missile defense system for months, and I was at the point where I needed to find a manufacturer who could make power cords containing a braid, shield, and drain. Finding a Military Grade AC Power Cord Cable Manufacturer | An Interview with Ryan Sollmann Can you tell me about your initial experience looking for a military ac power cord manufacturer? He's been kind enough to volunteer his story for this blog post, which highlights what he had to endure in order to find a manufacturer who could fulfill the needs of his military customer. Ryan Sollmann is a Sales Manager and EMI Filter Design Engineer at the Captor Corporation, who sells complex hardware solutions to the United States military. After talking to two other manufacturers unsuccessfully, Ryan reached Almor on his third try to find a cable manufacturer who understood his customer's EMI/RFI cable shielding needs. Our customer and respected colleague Ryan Sollmann had an especially challenging experience. We've heard multiple stories from our customers regarding just how hard it is to find a military grade ac power cord manufacturer. 1/14/2024 0 Comments Docker container startup timeThe container runtime is the low-level component that creates and runs containers. The containerd daemon is a central aspect of the Kubernetes CRI that enables Kubernetes to interact with various container runtimes, such as runC and Kata Containers. Containerd manages the container environment and oversees execution. The Docker engine doesn't manage containers directly, but instead relies on a separate module or high-level daemon process - part of the Docker package - called containerd. Docker provides a command-line interface - the CLI, or "console" - named docker-cli that users wield to build images, create container registries, load images from container registries and then start and manage containers. A key part of the container engine is the UI. Docker provides a comprehensive platform for developers and systems administrators - such as DevOps users. A platform such as Docker installs on a server or development computer and includes all the tools and utilities needed to build and run containers. The container engine sits at the very top of the container stack. Running containers in the Docker environment requires four fundamental components: the Docker engine/interface, the underlying daemon, the runtime and the container itself. The relationship between engines, runtimes and standardized interfaces is illustrated in Figure 1. CRI-O turns Kubernetes into a container engine that supports runC and Kata Containers as container runtimes for Kubernetes pods - though any OCI-compliant runtime should work. The Kubernetes Container Runtime Interface (CRI) provides an API that connects Kubernetes to container runtimes.ĬRI-O is an implementation of CRI which enables Kubernetes to use any OCI-compatible runtimes - rather than using Docker as the runtime for Kubernetes. This means Kubernetes must handle an array of container image formats - especially when creating and managing pods and clusters. OCI uses runC, which other engines, such as Docker and CRI-O, can also use - enabling greater container compatibility across container engines.Ĭontainers put an enormous value on orchestration, relying on vital tools like Kubernetes to automate and manage containerized applications and environments within the local data center, as well as in the cloud. This leads to refined and reliable container runtime tools.Īlthough there are several container image formats, the Open Container Initiative (OCI) has emerged as a popular and accepted standard for container images and runtimes. Standards streamline the methodology used to mount and run container images as containers. By applying standards to container image formats and associated metadata, the container industry can develop images and tools that are more refined, secure and interoperable. Standardization is an important part of container technology. The most common runtime is runC, but other container runtimes include crun, railcar and Kata Containers. For an OS such as Red Hat Enterprise Linux, the runtime would set up cgroups, set SELinux policy, set AppArmor rules and so on. Finally, it calls and hands off the container to a container runtime to start and manage the container's deployment.Ī container runtime is a low-level component of a container engine that mounts the container and works with the OS kernel to start and support the containerization process. The engine takes user input, interacts with a container orchestrator, loads the container image file (from a repository, usually stored in a cloud service, either public or private) and prepares storage to run the container. Typical container engines include Docker, CRI-O, RKT and LXD. A container engine is a general software platform that supports container use. VMs are completely isolated entities, however, whereas containers share the underlying OS kernel, which enables containers to be far smaller, faster and exist in greater numbers on a computer compared to traditional VMs.Ĭontainers require a container engine. This improves the computer's resource utilization and saves money - because more computing work can be performed on fewer servers. As with most VMs, multiple containers can exist on the same physical computer. What are containers, container engines and container runtimes?Ī container is a special type of virtual machine. Let's take a closer look at the roles and relationships of containers, engines and runtimes, and consider some of the implications involved. But the decision can have important consequences for the enterprise. There are several container runtimes available today, and the choice of runtime is often governed by the choice of container engine. 1/14/2024 0 Comments Fatal1ty gamer headset hs 800With the in-line volume control, you can easily control your sound level or mute the microphone.įor the serious gamer, the Fatal1ty Gaming Headset does make the difference between victory and defeat.

Everyone was so excited for a gorgeous indie Animal Crossing style game, but did it live up to that hype? Initially, I didn’t think so. It's so much more accurate than just dropping them where you stand.Cozy Grove was an indie darling when it was released earlier in the year. Pro-Tip : When placing objects, put them in your hand first, then throw them to the spot you want them to be in. That might not suit some people, but I'm sure I wont be the only person who finds this suitable. Other than that, it's a nifty little thing, that's meant to be played for 30 to 60 minutes per day.

Note that it is necessary to pass in the expected hostname explicitly (as a charlist): it is not extracted from the URL passed into HTTPotion/ ibrowse, since they are not aware of the verify_fun callback, nor by the Erlang ssl module since it never sees the URL. Now then, let’s get started with our first client… HTTPoison (hackey) In a follow-up post I will explain how you can build your own TLS test server using Phoenix in just a few lines of code, and how to use the OpenSSL CLI to debug handshake issues. - this URL will serve up the site using the regular site’s certificate the client should detect the hostname mismatch and abort the TLS handshake.- this URL will serve up the site using a self-signed certificate a client should not complete the TLS handshake unless explicitly allowed by the user.- the regular site, with a valid (at the time of writing) certificate issued through Let’s Encrypt.UPDATE: Please note that the test endpoints are no longer available! We will be using this blog as a test server for the various scenarios: If changes don’t seem to have any effect from one request to the next, restart your application or iex session to make sure a fresh TLS handshake will take place. Important note: most HTTP clients include a connection pool, and Erlang’s ssl module supports session resumption, which can lead to unexpected behaviour while experimenting with different TLS options. Now run iex -S mix and you’re ready to start interactively exploring the HTTP client APIs. You may also want to have a set of trusted CA certificates available. If you want to follow along, create a new project using mix new, edit your mix.exs file to list the package and application dependencies as shown below and then run mix deps.get. httpc - Erlang/OTP’s built-in HTTP client.HTTPoison - the most popular HTTP client on hex.pm, powered by hackney. Developers might expect an HTTP client that accepts HTTPS URLs to take care of these things, but things aren’t always that simple, as we shall see… Requests often contain sensitive data, such as API keys or personal information, that must be protected against eavesdropping and man-in-the-middle attacks. In many Elixir applications, an HTTP client is used to connect to 3rd party API servers a such as AWS, Facebook or Google. Instead it tries to establish what it takes to use these clients to connect securely to a server, given an HTTPS URL. The goal of this post is not to compare features, performance or usability, or even to choose a ‘most secure’ client. It’s a topic I covered in my ElixirConf EU talk, but it recently came up again. A better title would be: “On the security posture of Elixir HTTPS clients”. Let me start off by apologising for the click-bait title. |
