海外TECH	DEV Community	Software Development is About Compromise	https://dev.to/awwsmm/software-development-is-about-compromise-352b	Software Development is About Compromise Trade Offs in Software Development Where s all my CPU and memory gone thegeomaster Software development is and has always been about trade offs The CAP theorem tells us that we need to choose between consistency availability and partition tolerance when designing distributed data stores Caches can make information available more quickly but it might be out of date and it will definitely use more storage space than making a fresh request each time And as always money can be a factor SSDs are faster than HDDs but they are more expensive per GB And microservices in a distributed system should each have their own database but cloud computing costs can mean that shared DBs are more cost effective Weighing the pros and cons of varied solutions to a problem was something I needed to tackle recently when redesigning part of my personal website awwsmm com Here s how that went down A Case Study My Website The SetupMy website is a pretty minimal Next js site written in TypeScript hosted on GitHub built and deployed by Vercel In general Next js allows you to have two kinds of pages static pre rendered pages and dynamic pages rendered just in time when a visitor to your website tries to visit that page My website has static blog posts as well as project pages which give a quick overview of personal projects that I ve been working on lately My initial design was for a given project page for example this one for my website itself to have an up to date commit history interleaved with occasional log entries summarizing big sweeping changes made to these projects Kind of like release notes but with more detail behind why certain changes are being made So what was the problem The ProblemThe problem was that these project pages were statically rendered they were built in advance I would request the commit history of a project from GitHub and write it to a local cache saved in the repository When a new PR is opened against the repo containing my website Vercel runs a test deployment When the test deployment looks good I hit merge and the new changes are added to the repo in a merge commit But because the cache is created only when I m developing locally this merge commit is not a part of the commit history in the cache It couldn t possibly be It would require updating the cache file which would introduce changes not included in that commit which would require another commit ad infinitum This means that the commit history for the awwsmm com project page is always at least one commit behind master This bothered me and I wanted to see if I could fix it First Attempt Environment Aware CachingMy first attempt at a solution was what I m going to call environment aware caching What if after the deployment passed and the new PR was merged into master Vercel ignored the cache only using it as a backup During deployment we could hit the GitHub API again which should then have the new commit right This required knowing which environment the build was running on This is straightforward as Vercel populates a VERCEL ENV environment variable to production preview or deployment depending on where the build is running But this also required maintaining a cache which we hopefully would never fall back to which seemed kind of silly It also meant that each release would have to be deployed at least twice once to satisfy the checks before merging the PR and once after the PR was merged to pick up the new commit on master I d have to remember to do this double deployment to keep things up to date Finally there was some human error here in that I tried to use the same caching mechanism for last updated dates on my blog posts confusing the issue All in all this solution was pretty complex to maintain all I want is a static blog and it put me off of keeping my website up to date for a while When I finally came back here after a few months I decided that a simpler solution was in order Second Attempt Server Side RenderingSo how about trying to render the project pages just in time Vercel s server side rendering SSR also generates static pages but it renders them only when the user navigates to the page not during deployment This is great I thought I could just request the commit history when the page is requested and it would always be up to date Unfortunately requesting and processing commits from GitHub seemed to be too much to ask I was consistently waiting about seconds for the page to load which is really bad Project pages with shorter commit histories loaded a bit faster but there was still a noticeable delay Sending the request to GitHub awaiting a response processing the response generating the resulting page and displaying it just took too much time This approach would also send a request to GitHub every time a user loaded that page This second issue could be solved by fine tuning the Cache Control header sent along with the request such that I could guarantee that the requests per hour authenticated limit would never be exceeded But the first issue remained a problem Third Attempt Non Blocking Server Side Rendering Maybe I m the problem I thought Maybe it s the way I think I am blocking inside of getServerSideProps I rearranged this method to not await anywhere but return a Promise which is a result of other Promises chained together with then and nothing else I was hoping that with everything done in a non blocking way in the return value Vercel could work some magic to speed up the call Maybe it could run the request as soon as the user hovered over the link to the page But it didn t help I was still stuck at seconds of loading time Worth a try at least Fourth Attempt GraphQL Maybe the response from GitHub is taking so long because it s returning too much data I wasn t using most of the response anyway all I cared about was the commit hash the message and the date I d never used GraphQL before but I knew that it could be used in situations like this where you wanted to request only particular data from an endpoint So I learned enough about GraphQL and GitHub s API to request only the commit data I cared about This sped up the page a bit locally but not in production on Vercel It was still taking about seconds Fifth Attempt Timeout Fallback to Cache Well if it s loading fast enough locally but not remotely maybe I can set a timeout threshold My thought was that I could cache a stale version of the page to display if the live version of the page took too long to load Maybe longer than ms or so So I would now generate a cache when building locally and save the cache to the repo In production I would attempt to request fresh data from GitHub but if it took longer than ms I would fall back to the cache but it still took seconds to render the page remotely Why I thought pulling my hair out in frustration Other project pages loaded quickly maybe Vercel was just somwehow slow to process this line JSON file generate the hundreds of components for it style all of them and display them I found issues on the vercel repo of people complaining about similar problems Maybe it just took a few seconds for Vercel to spin up a runner to render the page That didn t seem to square with the load times of the other project pages I took solace in the fact that other people on the Internet also thought that getServerSideProps is weird and unintuitive I assessed other possible avenues for investigation timing the response actually reading the docs no thanks incremental static generation edge functions I was beginning to lose the will to live all I wanted was a blog RegroupingI took a breather and came back to it all after a little while What is it I actually want up to date commit historiesfast page loadsThe problem was that those two things were if not mutually exclusive at least in competition with each other Up to the second commit histories would require a request to GitHub as soon as the user requested the project page Which meant that all of the data fetching and processing and rendering would have to be done quickly This didn t seem like too big of an ask to me but apparently it was Maybe it was my code maybe it was the Lambda cold start times maybe it was something on Vercel s end whatever it was it was pinning me to second page load times Maybe I can request and process most of the history in advance then only request recent history when a user clicks on a page This sounded overcomplicated though Unlikely but what if a project had had new commits since I last deployed my website and generated the cache Then I would have the same problem trying to request and render commits onto this history page So I compromised and came up with a simpler solution generate project pages staticallyThis solves the load time issue by the time we get to production the pages will have already been generated so nothing needs to be done except displaying them But this means that we will not have an up to date commit history accept that the commit history will not be up to dateI d already sunk so much time into this I was ready to compromise Nobody coming to my website will care if my commit histories are slightly out of date So I decided to just put a disclaimer at the top and bottom of the histories saying something like for the most up to date commit history see GitHub Now we can generate pages in advance keep load times to basically zero and we don t have to worry about complex caching solutions or what environment the build is running in or GitHub rate limits or anything My compromise was that my time and energy were worth more to me than having this one feature on my website be exactly the way I had envisioned it initially Software Development is About CompromiseIn my case I tried and tried to get my website to do what I wanted it to but my two requirements up to date commit histories and fast loading times were in direct competition with each other Having an up to date history will require a request when the user clicks the button and processing the result of that request which will take time Surely there are more complex solutions which balance these two better but in the end having these pages be up to date is not critical for my blog Choosing where to use my time is another trade off I learned a lot about Vercel GraphQL and Promises in JavaScript TypeScript during this process but ultimately see GitHub is good enough for me And that s a compromise I m willing to accept	2023-04-10 13:39:01
海外TECH	DEV Community	Use GitHub Actions to Make Your GitHub Profile Dynamic	https://dev.to/bengreenberg/use-github-actions-to-make-your-github-profile-dynamic-3af3	Use GitHub Actions to Make Your GitHub Profile DynamicWhere do people first discover you online Perhaps your social media presence is the first thing people find when they search for you or perhaps it s the portfolio site you created for yourself However if you use GitHub to share your code and participate in open source projects then your GitHub profile may be the first place people go to in order to learn more about you What do you want your GitHub profile to say about you How do you want to express what is important to you and who you are in a concise and easy to read manner for visitors Whether they are a prospective employer or a prospective partner in an open source project it s imperative you have a profile that stands out Using GitHub Actions you can turn a static markdown document into a dynamic experience that stays up to date on the latest information about you How do you do that I ll show you an example of how you can do this quickly and without too much effort In this example you ll learn how to scrape a website and use that data to dynamically update your GitHub profile We ll show this example in Ruby but you can do this with JavaScript TypeScript Python or other languages How Your GitHub Profile WorksYour GitHub profile is found by going to github com your username in a web browser here s mine for example Where does the content for that view come from It lives in a special repository in your account with the name of your account username If you do not have this repository yet you will not see any special content when you visit github com your username so the first step is to ensure you have that repository created and if you do not go ahead and create it Exploring the files in the profile repositoryThe only required file in the repository is a README md file that is the source of your profile page ├ーREADME mdGo ahead and add some content in that file save it and refresh your username homepage and you will see that content reflected there Adding the right folders for dynamic contentBefore we create the code to make our profile dynamic let s add the folder structure Inside the top level add a new folder called github and inside github add two new sub folders scripts and workflows Your file structure should now look like this ├ー github │├ーscripts │└ーworkflows └ーREADME md Making a Dynamic ProfileWe need to do three things for this example Define a place in the README where the dynamic content will beAdd a script inside scripts that will do the scraping workAdd a workflow for GitHub Actions inside workflows that will run the script on a scheduleLet s do each of those steps now Updating the READMEWe need to add a section to the README that can be grabbed using Regex by the script to modify It can be whatever you need it to be for your specific use case For this example we ll add a section for recent blog posts in the README Open up the README md file in a code editor and add the following Recent blog postsNow we have an area for the script to find Creating the scriptThe example script we are building is written in Ruby and uses the GitHub gem octokit to interact with your repository the nokogiri gem to scrape the website and the httparty gem to make the HTTP request In this example below the element to be scraped has already been identified In your own use case you ll need to discover the path to the element on the site you wish to scrape and it will undoubtedly be different than what is shown below as defined in the posts variable and for each title and link of each post Here is the example code which goes in the scripts folder require httparty require nokogiri require octokit Scrape blog posts from the websiteurl response HTTParty get url parsed page Nokogiri HTML response body posts parsed page css flex flex col rounded lg shadow lg overflow hidden Generate the updated blog posts list top posts list n Recent Blog Posts n n posts first each do post title post css p text xl font semibold text gray text strip link post at css a href posts list lt lt title link end Update the README md fileclient Octokit Client new access token ENV GITHUB TOKEN repo ENV GITHUB REPOSITORY readme client readme repo readme content Base decode readme content force encoding UTF Replace the existing blog posts sectionposts regex Recent Blog Posts n n s S lt td gt mupdated content readme content sub posts regex posts list join n n client update contents repo README md Update recent blog posts readme sha updated content As you can see first an HTTP request is made to the website and the section with the blog posts is gathered and the data is assigned to a posts variable Then the script iterates through the blog posts inside the posts variable and gathers the first of them You may want to change that number for your own needs Each loop through the blog posts a post is added to an array of posts list with the title and the URL to the blog post Lastly the README file is updated by first finding it using the octokit gem and then locating the spot in the README to update with some regex posts regex Recent Blog Posts n n s S lt td gt m This script will do the job but nothing is actually invoking this script How does it get run This is where GitHub Actions comes to the rescue Creating the Action workflowNow that we have the script in place we need a way to automatically run it on a schedule GitHub Actions provides a powerful way to automate a wide variety of tasks including running scripts In this case we ll create a GitHub Actions workflow that runs the script once a week at midnight on Sunday The workflow file should be placed in the github workflows directory and can be named something like update blog posts yml Here s the content of the workflow file name Update Recent Blog Postson schedule cron Run once a week at midnight on Sunday workflow dispatch jobs update posts runs on ubuntu latest steps name Check out repository uses actions checkout v name Set up Ruby uses ruby setup ruby v with ruby version name Install dependencies run gem install httparty nokogiri octokit name Scrape posts and update README run ruby github scripts update posts rb env GITHUB TOKEN secrets GITHUB TOKEN GITHUB REPOSITORY github repository This workflow is triggered on a schedule defined by the cron syntax which specifies that it should run at midnight every Sunday Additionally the workflow can be manually triggered using the workflow dispatch event The update posts job consists of several steps Checking out the repository using the actions checkout v action Setting up Ruby using the ruby setup ruby v action with the specified Ruby version of Installing the required Ruby gems httparty nokogiri and octokit using the gem install command Running the script update posts rb located in the github scripts directory The GITHUB TOKEN and GITHUB REPOSITORY environment variables are provided to the script allowing it to interact with the repository With this workflow in place your script will automatically run every week to scrape the blog posts and update the README file GitHub Actions takes care of all the scheduling and execution making the process seamless and efficient Putting it all TogetherNowadays your online presence is often the first point of contact for people looking to connect with youーwhether they re prospective employers collaborators or contributors to open source projects Your GitHub profile in particular is a valuable platform for showcasing your skills projects and interests So how can you ensure that your GitHub profile remains up to date relevant and truly reflective of who you are By harnessing the power of GitHub Actions we ve demonstrated how you can transform your GitHub profile from a static Markdown document into a dynamic ever changing example of who you are Through the example provided in this guide you ve learned how to scrape data from a website and use it to dynamically update your GitHub profile And while our example was implemented in Ruby the same principles can be applied using JavaScript TypeScript Python or any other language of your choice To recap we walked through the process of creating a Ruby script that scrapes blog posts from a website extracts relevant information and updates the Recent Blog Posts section of your README md file Then we used GitHub Actions to set up a workflow that runs the script on a regular schedule ensuring that your profile remains current with your latest content But our journey doesn t end here The techniques and approaches shared in this guide can serve as a foundation for further exploration and creativity Whether it s pulling in data from other sources integrating with APIs or experimenting with different content formats the possibilities are endless So go ahead and make your GitHub profile a vibrant and dynamic extension of yourself Let it tell your story highlight your achievements and invite collaboration with others Was this blog post helpful Consider sponsoring my work on GitHub to help me create more content like this ️	2023-04-10 13:27:28

are Containers A Detailed LookContainers have revolutionized the way we build package and deploy applications leading to a more efficient and agile software development process In this section we will explore the concept of containers in greater detail examining their history core components and the technologies that enable them The Evolution of ContainersThe concept of containerization has its roots in the UNIX operating system s early days Unix introduced the concept of process isolation where each process runs independently in its own address space isolated from other processes This concept has evolved over time with technologies such as chroot and Solaris Zones providing more advanced forms of process isolation The modern containerization era began with the introduction of Linux Containers LXC in LXC leveraged Linux kernel features such as cgroups and namespaces to provide lightweight portable and isolated environments for running applications However LXC s user experience and tooling were relatively complex and limited Docker launched in was built on LXC s foundational concepts but simplified container management and deployment by providing a user friendly command line interface and API Docker also introduced the concept of container images which made it easier to package distribute and version applications Docker s success led to the widespread adoption of containers in the software industry Core Components of ContainersA container consists of several core components including Application Code The actual software or application that is being containerized Runtime The execution environment required for the application such as Node js Python or NET Libraries Shared libraries and dependencies required by the application System Tools Utilities and tools required by the application or the runtime Configuration Files Files that define the application s settings and environment variables Container Runtimes and the OCIContainer runtimes are responsible for creating running and managing containers The most popular container runtime is Docker which provides a comprehensive set of tools for building packaging and deploying containers However there are alternative container runtimes such as containerd and CRI O which offer different features and performance characteristics The Open Container Initiative OCI is a collaborative project under the Linux Foundation that aims to create open standards for container runtimes and images The OCI has defined two specifications the Runtime Specification runtime spec and the Image Specification image spec These specifications ensure compatibility and interoperability between different container runtimes and registries Containers vs Virtual MachinesWhile both containers and virtual machines VMs provide isolated environments for running applications they differ in their approach and resource utilization VMs rely on a hypervisor to emulate an entire operating system and hardware stack for each instance This results in significant overhead as each VM runs a complete OS and duplicates system resources Containers on the other hand share the host s OS kernel and use lightweight runtime environments leading to significantly lower resource usage and faster startup times While VMs provide stronger isolation between instances containers offer a more efficient solution for deploying and managing applications at scale In conclusion containers are a powerful technology that has transformed the way we develop package and deploy software They provide a lightweight portable and consistent environment for applications enabling developers to focus on writing code without worrying about infrastructure complexities As we move forward in this article series we will explore the Azure Container Services and learn how to leverage containerization to build and deploy applications on the Azure cloud platform Exploring Container RuntimesContainers have become an integral part of modern software development enabling consistent portable and efficient application deployment At the heart of containerization are container runtimes which are responsible for creating running and managing containers In this article we will explore various container runtimes their features and their role in the container ecosystem What is a Container Runtime A container runtime is a software component responsible for executing and managing containers on a host system It interacts with the container s image unpacks the layers sets up the necessary isolation features and runs the application code within the container Container runtimes are responsible for providing the low level functionality required for containerization such as process isolation resource management and networking Docker The Pioneer of Modern Containerization Docker is the most widely adopted container runtime and has played a crucial role in popularizing containerization Docker s primary components include Docker Engine The core component responsible for building running and managing containers Docker CLI A command line interface for interacting with the Docker Engine Docker API A RESTful API for programmatically interacting with the Docker Engine Docker Compose A tool for defining and running multi container applications using a single configuration file Docker s success stems from its simplicity powerful tooling and vast ecosystem of container images available on Docker Hub Open Container Initiative OCI and StandardizationThe Open Container Initiative OCI is a project under the Linux Foundation that aims to establish open standards for container runtimes and image formats The OCI has two primary specifications Runtime Specification runtime spec A standard for container runtime behavior ensuring compatibility and interoperability between various runtimes Image Specification image spec A standard for the container image format ensuring container images can be used across different runtimes The OCI has played a crucial role in enabling a diverse ecosystem of container runtimes while maintaining compatibility and consistency Alternative Container RuntimesApart from Docker several alternative container runtimes have emerged each offering unique features and capabilities containerd containerd is a lightweight container runtime designed for simplicity and performance Originally developed as part of the Docker project containerd has since become an independent project and an OCI compliant runtime containerd is widely used in Kubernetes environments and is the default runtime for Docker Engine CRI O CRI O is a Kubernetes native container runtime focused on simplicity stability and performance CRI O is built around the Kubernetes Container Runtime Interface CRI and is designed specifically for running Kubernetes workloads It supports OCI compliant container images and offers a minimalistic runtime experience Podman Podman is a daemonless container engine that aims to provide a Docker compatible experience without the need for a central daemon Podman supports the same command line interface as Docker and is capable of running OCI compliant container images One of Podman s unique features is its support for rootless containers which allows running containers without requiring root privileges rkt rkt pronounced rocket is a container runtime developed by CoreOS that emphasizes security simplicity and composability rkt is designed to be easily embedded in other applications and supports multiple container image formats including Docker and OCI images However development on rkt has slowed down since the acquisition of CoreOS by Red Hat Choosing the Right Container RuntimeSelecting the appropriate container runtime depends on your specific needs and the requirements of your environment Factors to consider when choosing a container runtime include Compatibility Ensure the runtime is compatible with your existing infrastructure tools and container image formats Performance Evaluate the runtime s resource consumption startup times and overall performance characteristics Security Consider the runtime s security features such as rootless containers SELinux integration and secure container isolation Simplicity Assess the ease of use tooling and documentation provided by the runtime Community and Ecosystem Analyze the community support development activity and availability of third party integrations and plugins ConclusionContainer runtimes play a critical role in the container ecosystem providing the foundation for creating running and managing containerized applications Docker has been the driving force behind the widespread adoption of containerization but alternative container runtimes like containerd CRI O Podman and rkt offer unique features and capabilities that may better suit specific use cases and environments Understanding the different container runtimes and their features will help you make informed decisions when selecting the appropriate runtime for your projects As the container ecosystem continues to evolve we can expect further innovation and improvements in container runtime technologies enabling more efficient secure and powerful containerized application deployment Mastering Container ManagementAs containerized applications grow in complexity and scale managing their deployment scaling and networking becomes increasingly challenging Container management software also known as container orchestration tools play a crucial role in automating and simplifying these tasks In this article we will explore various container management solutions their features and their role in the container ecosystem What is Container Management Software Container management software is a set of tools and platforms designed to automate the deployment scaling and management of containerized applications These tools provide advanced features such as automated scaling rolling updates self healing and load balancing to ensure the reliability availability and performance of containerized applications in production environments Key Features of Container Management SoftwareScheduling Deploying containers to appropriate hosts based on resource availability and constraints Scaling Automatically scaling applications based on demand either by increasing or decreasing the number of container instances Networking Managing container networking including load balancing service discovery and network segmentation Storage Managing persistent storage for stateful applications including volume provisioning and data persistence Monitoring Collecting and analyzing container metrics logs and health status for improved observability and troubleshooting Security Ensuring container security through features like role based access control RBAC secrets management and network policies Popular Container Management Solutions KubernetesKubernetes is an open source container orchestration platform developed by Google and donated to the Cloud Native Computing Foundation CNCF It has become the de facto standard for container management and provides a robust and extensible framework for deploying scaling and managing containerized applications Kubernetes supports a wide variety of container runtimes including Docker containerd and CRI O Docker SwarmDocker Swarm is a native clustering and orchestration solution built into the Docker Engine It provides a simpler and more integrated experience for users already familiar with Docker Docker Swarm enables users to create and manage a swarm of Docker nodes and deploy services across those nodes While not as feature rich as Kubernetes Docker Swarm is an excellent choice for small scale deployments and users seeking a straightforward container management solution Apache MesosApache Mesos is a distributed systems kernel that abstracts compute resources across a cluster of machines Mesos can manage resources for both containerized and non containerized workloads Marathon a framework built on top of Mesos provides container orchestration capabilities similar to Kubernetes Mesos is well suited for

海外TECH	Engadget	The best kitchen gadgets for 2023	https://www.engadget.com/best-kitchen-tech-gadgets-small-appliances-124515179.html?src=rss	The best kitchen gadgets for At the most basic level the only kitchen equipment you really need are a knife cutting board a heatproof vessel of some kind and perhaps a utensil or two But if you really want to take your cooking to the next level and who doesn t you ll want to invest in a few accoutrements From pressure cookers to toaster ovens these are our favorite kitchen must haves that will make cooking easier faster and maybe even more enjoyable Best multi cooker Instant Pot Duo PlusIf you haven t yet hopped on the bandwagon a multi cooker like the Instant Pot could become part of your regular rotation This cult favorite can perform multiple tasks including pressure cooking slow cooking sautéing rice cooking yogurt making steaming and warming The combination of all these features make it easy to prepare stews soups braises and more You can make cheesecake in it too Our favorite model for most people is the Instant Pot Duo Plus because it s simple to use with several quick cooking modes for soup eggs porridge and grains It has sterilizing and sous vide cooking functions too Want a smarter Instant Pot instead Consider the Instant Pot Pro Plus It not only has updated features like a canning function and an oven safe inner pot but you also get WiFi connectivity and a companion app which offers step by step guided instructions for over recipes Plus you can use it to release the Instant Pot s steam remotely You can also use the app to set a timer to release the steam automatically Best thermometer Thermapen OneNobody wants to eat undercooked meat but it s pretty inedible when it s overcooked as well One way to avoid either extreme is to use a thermometer to monitor the temperature Our favorite is the Thermapen One from ThermoWorks It gives readings instantaneously and the screen rotates automatically depending on how you re holding it The auto wake and sleep feature is useful for quick temp checks and its IP waterproofing rating means you don t have to worry about accidentally dropping it in the sink The ThermoPop is a more affordable option in ThermoWorks lineup It s not quite as fast as the Thermapen One and it doesn t have the rotating display or backlight But it still measures temperatures accurately and while it s not waterproof it is splash resistant Best food scale Escali PrimoBakers everywhere know that the most precise way to measure ingredients is with a scale A “cup of flour can be wildly different depending on how you scoop it while a scale can tell you exactly if you have grams A digital scale is best for the most accurate measurements and we especially like the Escali Primo You can switch between grams and ounces with a single press and importantly there s also a tare button that zeros out the weight so you can keep measuring in the same container One reason we like the Escali Primo over other models is that it has a very long auto off timer allowing it to stay on for four minutes before shutting off That s important for when you need the extra time to chop up vegetables or gather other ingredients without having to worry about the scale resetting to zero Best air fryer Instant Vortex PlusThe hottest kitchen gadget right now seems to be the air fryer presumably because the idea of “frying foods without the oily mess is an easy sell Really though air fryers are just miniature convection ovens They re typically pod shaped and often come with a removable basket There are also toaster ovens with an air frying function see our recommendations below if you prefer to have a multi purpose appliance Though both have their own merits if you think you re going to be air frying a lot we actually recommend a dedicated pod shaped air fryer These devices tend to result in crispier food plus they re easier to clean One of our favorites is the Instant Vortex Plus with ClearCook and OdorErase As the name suggests it has a window so you can see what you re cooking as well as odor eliminating filters that help reduce cooking smells not many other air fryers have both It also doesn t take up as much space as a large toaster oven and it has easy to use controls Best stand mixer KitchenAid Artisan seriesSure you could probably mix together a batch of cookie dough by hand but it ll take time and quite a bit of upper body strength That s even truer if you want to knead bread dough or whip up a meringue Save yourself the trouble by getting a stand mixer The favorite among bakers and amateur cooks for years have been KitchenAid s Artisan series It s durable powerful and it comes with your choice of paddle hook and whisk attachments We also like that the KitchenAid mixers are compatible with a variety of accessories and attachments that can turn the machine into an ice cream maker a meat grinder and a pasta machine just in case you want to expand your culinary horizons Best blender Vitamix Explorian seriesIt s hard to beat the Vitamix in this space The high performance blender brand makes machines that do more than just prep smoothies but can also make sauces batters and soups It s especially handy if you have a habit of adding tougher ingredients into your recipes things like nuts dried fruit and frozen produce Whereas other less powerful blenders may leave chunks once you introduce hardier ingredients the Vitamix won t leaving you with a silky smooth final product Depending on the model you get you can also buy different attachments to make the most of the blender s powerful base You can pick up ounce containers for making smoothies for your whole family at once or a “dry grain container that s outfitted with a blade specifically for grinding up things like whole grains so you can make your own flour Vitamix currently has four series of blenders the basic Vitamix One which comes in at the slightly more advanced Explorian series which starts at and is arguably best for most people the Legacy series starting at and the advanced Ascent series which will set you back at least Yes these are expensive machines but it s worth investing in if you do a lot of blending or like to experiment with making things from scratch Best toaster oven Breville Smart Oven Air Fryer ProA toaster oven is a surprisingly versatile appliance Yes you can use it to toast bread buns and all manner of baked goods But it s also a great alternative when you don t want to warm up your whole house with your full size oven It heats up far faster too which makes it a more efficient choice for warming up leftovers We love the Breville Smart Oven Air Fryer Pro as it s big enough to roast a chicken and it also has other functions like dehydrate proof and air fry thanks to a super convection mode It also includes presets for baking pizzas and toasting bagels A step up from that is the Joule Oven Air Fryer Pro which adds WiFi connectivity so you can control it from your phone The app has lots of recipes too and there s an “autopilot feature that automatically adjusts the temperature during cooking If you don t want something quite so large a smaller and more affordable alternative is the Panasonic Flash Express It s roomy enough to handle a slice of pizza but definitely won t take up as much space as the Breville It s definitely a great option if all you want is a toaster oven for heating up frozen snacks or toasting several bread slices at once Best sous vide machine Anova Precision Cooker If you want to make sure your expensive steak is perfectly medium rare without having to constantly monitor its temperature consider getting a sous vide cooker These machines let you cook anything inside a temperature controlled water bath so that it s done to perfection We ve successfully made steak chicken burgers eggs and even yogurt in a sous vide cooker and the results have been perfect every time Our favorite model is the Anova Precision Cooker The company added digital touch controls a longer power cord and WiFi connectivity to an already stellar base product with the launch of the latest version The companion app is thoughtfully designed as well with hundreds of recipes and the option to control the machine remotely And even though there s an app component you don t have to use it you can easily adjust the temperature with the on board controls and the large digital display Valentina Palladino contributed to this report This article originally appeared on Engadget at	2023-04-10
