Pros of using PostgreSQL Copy with Activerecord-copy You’ll also notice where I created the time stamp time = that’s because Rails will not create time stamps for you automatically with COPY. Note that when you use the activerecord-copy gem, the time stamp is not created for you automatically. The activerecord-copy gem adds a copy_from_client method to all your model classes, as shown in the snippet above (you’ll have to define the columns and their values as shown). foreach (filename, headers : true ) do |row | User. Task :single_record = > :environment do #This function loops over the content of the csv file and creates a new record for each of them. # lib/tasks/one_record_at_a_time.rake require 'csv' require "benchmark"ĭesc "imports data from csv to postgresql" Here’s a sample code to do this in Rails, assuming we have the source data in a CSV file: One easy way to load data to a Postgres database is to loop through the data and insert them one at a time.

Let’s look at four different methods, and then we’ll see which is the fastest. However, with the wrong tools and solutions, its powers can be undermined. PostgreSQL has a strong reputation for handling large data sets. According to a recent study by DB-Engines (PDF), PostgreSQL’s popularity rating increased by 65 percent from January 2016–January 2019, while the rating of MySQL, SQL Server, and Oracle decreased by 10–16 percent during the same period. We’ll go over their pros and cons, so you can choose the method that works best for your situation. In this article, I’ll explain a few ways to load data to a PostgreSQL database with Rails. There are several ways you can load data from an old Rails app or other application to Rails. Whether you are loading data from a legacy application to a new application or you just want to move data from one database to another, you’ll most likely need to create a migration script that will be accurate, efficient, and fast to help with the process - especially if you are planning to load a huge amount of data. Data migration is a delicate and sometimes complicated and time-consuming process.

We recommend that you get a device that has somewhere around 4GB minimum in RAM for optimal performance and at least 32GB in internal storage. So, for now, we have to wait a little for its arrival on the Android platform. Adobe Premiere Rush works well on devices using Android 9.0 and later. Adobe Premiere Rush is expected to attract the users who don’t have a powerful machine or the one who lack in skills. This thing by no means can replace the full-fledged PC programs but can be a lifesaver for the users who want a quick video edit to post on YouTube. It will be served with some templates which will eliminate the need of apps like After Effects. The app will allow a user to color correct the footage, add titles, and one will even be able to add motion graphics to their videos. The app will further allow a user to edit up to 4K videos on Laptop or a smartphone. As its name suggests the app is developed to make your work easier and faster. Adobe already has its Premiere Clip app for Android platform, however, with the fresh Premiere Rush Adobe will gonna decrease that gap between PC and smartphone programs. On PC platform a ton of editing programs including Adobe Premiere Pro, Adobe After Effects, etc are available but we can’t perform such things on our Android devices. In 2019 Adobe is bringing the final app of Rush for Android users as well. Adobe has introduced their Adobe Rush editing platform a long time back, however, till date, it was only available for Windows and iOS platform. Now some fresh information is there following which we can say that soon one will be able to edit their 4K videos on an Android smartphone. Adobe has always been in the talks whenever it comes to video editing or photo editing. It’s used across various scientific fields. TensorFlow is a library for high-performance numerical computations with around 35,000 comments and a vibrant community of around 1,500 contributors. The first in the list of python libraries for data science is TensorFlow. Now that we know the benfits, let us look at the top 20 Python libraries for data science: Overall, Python empowers data scientists with the tools and resources they need to efficiently explore, analyze, and derive insights from large and diverse datasets. Its integration capabilities with other languages and tools, along with its scalability and compatibility with various platforms, make Python a flexible choice for data science projects. Its simplicity and readability make it an accessible language for beginners, while its versatility allows experienced data scientists to build complex algorithms and workflows.Īdditionally, Python has a vast and active community that contributes to a rich ecosystem of resources, tutorials, and support. Firstly, Python provides a wide range of powerful libraries and frameworks, such as NumPy, Pandas, and SciPy, which offer extensive functionality for data manipulation, analysis, and modeling. The benefits of using Python for data science are manifold. Python has become a popular programming language for data science, and for good reason. Benefits Of Using Python For Data Science Python has been built with extraordinary Python libraries for data science that are used by programmers every day in solving problems. Python is an easy-to-learn, easy-to-debug, widely used, object-oriented, open-source, high-performance language, and there are many more benefits to Python programming. Most data scientists are already leveraging the power of Python programming every day. When it comes to solving data science tasks and challenges, Python never ceases to surprise its users. Python is the most widely used programming language today. For more details, see “How ode45 Works” on page. In those cases ode45 is almost always more accurate, for two reasons: first, it computes the rate function several times per time step second, if the time step is too big, ode45 can detect the problem and shrink the time step. However, for some problems, Euler’s method can be off by a lot more than 1 percent. Any of these modeling errors could be bigger than 1 percent. Also, the assumption that the growth rate only depends on population is probably not true. In this example, we probably don’t know the initial population with perfect accuracy or the growth constant, a. During the last hour, they diverge slightly at 4 hours, the difference is less than 1 percent.įor many purposes, the difference between Euler’s method and ode45 is the least of our worries. The solid line is the estimate we computed with Euler’s method the dashed line is the solution from ode45.įor the first 2–3 hours, the two solutions are visually indistinguishable. Figure 9.2: Solutions to a simple differential equation using Euler’s method and ode45 In order to store them, we have to assign them to two variables, T and Y. The ode45 function is the first function we’ve seen that returns two output variables. The third argument is the initial population, 5 billion cells. The second argument is the time interval where we want to evaluate the solution in this case the interval is from \(t=0\) to \(t=4\) hours. The first argument is a function handle, as we saw in Chapter. We can call ode45 from the Command Window like this: =, 5) Fortunately, we already have one, called rate_func: function res = rate_func(t, y) In order to use ode45, you have to write a function that evaluates \(dy/dt\) as a function of \(t\) and \(y\). In this section I’ll explain how to use it you can read more about how it works in “” on page. MATLAB provides a function called ode45 that implements one of these methods. Fortunately, there are better methods that estimate the derivative between time steps, and they are much more accurate. \)Ī limitation of Euler’s method is that it assumes that the derivative is constant between time steps, and that’s not generally true. Not only does this create a naturally non-stick cooking surface it also adds to the flavor of any food. The most important part of the flavor comes from the unique seasoning layer that builds up on the Flat Top with use. The reviews are in and customers agree: food just tastes better on a Flat Top. This larger thermal mass puts more heat into the food in less time for better sears and quicker cooking.Ģ. We use super-thick 3/16" steel on all of our standard Flat Tops that is over 50% thicker than a Blackstone Griddle and nearly 4x thicker than typical pans or skillets.

This transforms the raw silver steel into a gorgeous black finish with amazing non-stick properties without the use of dangerous coatings like Teflon that only gets better with time. For the uninitiated, "seasoning" refers to a natural chemical reaction where oil and fat are heated to the point where they literally bake into the steel through a process called polymerization. If you've ever owned cast iron cookware, you're probably already familiar with the term. The seasoning process is literally the black magic of Flat Top ownership. The front of the Flat Top features a small 5 degree break to prevent accidental spills without interfering with any of the important features of our three-sided design. What seems like a bold design choice actually creates critical airflow to keep food from getting soggy while providing easy access to the food when cooking.

Variety sat down with Sorkin and Thomas to discuss their love for the theater and how their current play is timelier than ever. It’s a busy time for Thomas, who is set to reprise his iconic, Emmy-winning “The Waltons” role in “A Waltons Thanksgiving,” airing Nov. With direction from Bartlett Sher, who earned a Tony nom for his work, the lead role of Atticus is played by stage and screen veteran Richard Thomas. When Atticus chooses to represent Tom Robinson, a Black man falsely accused of rape, Scout begins to experience a loss of innocence as she grapple with concepts of racism and justice. The story is set in Depression Era Alabama and told through the eyes of Scout, Atticus Finch’s six-year-old daughter. on a national tour, where it’s currently playing at the Hollywood Pantages Theatre through Nov. Now the play is making its way across the U.S. It would go on to receive nine Tony nominations before being shut down by the COVID-19 pandemic. But the writer set his fears aside in 2018, “To Kill a Mockingbird” opened on Broadway with Jeff Daniels in the lead to positive reviews and record-breaking box office. Harper Lee’s 1960 novel remains a beloved American classic, as does the 1962 film adaptation that earned Gregory Peck an Oscar for playing small-town lawyer Atticus Finch. Even with an Academy Award and six Emmys on his mantel, Aaron Sorkin was intimidated by the idea of a bringing “ To Kill a Mockingbird” to the stage. The company no longer develops Sketchup Make, its free desktop software, but you can download it from Trimble's archives.

One of the most popular designs for negative space blackout tattoos is the silhouette or cutout image.Not only will this ensure that the final result is aesthetically pleasing, but it will also minimize the risk of complications and the need for touch-ups down the line. If you’re considering getting a negative space blackout tattoo, it’s important to do your research and find an artist who is experienced in this particular style. However, not all artists are skilled in this technique, and the outcome of the tattoo will depend largely on the artist’s expertise. When executed correctly, these tattoos can be a visually stunning and striking way to adorn your body. Negative space blackout tattoos are a unique form of body art that uses the skin’s natural color as the background to create an image. Unique Designs And Techniques Of Negative Space Blackout Tattoos And as always, be sure to take proper care of your tattoo during the healing process to ensure it looks its best in the long run. If you’re considering this type of tattoo, be sure to do your research and find a skilled artist who has experience working with negative space. While there are both pros and cons to getting a negative space blackout tattoo, it’s ultimately up to the individual to decide if this type of design is right for them. Not all tattoo artists are skilled in this technique.May be more painful due to the solid black background.It’s a technique that requires a skilled tattoo artist who can work with both positive and negative space to create a visually stunning result. Some designs might use negative space to create bold, graphic shapes, while others might use it to highlight specific details within the design. This technique can be used in a variety of ways to create a one-of-a-kind tattoo. This creates a striking contrast between the black background and the blank space of the design. Rather than filling in the design with ink, the artist creates a solid black background around the design, leaving the design itself uncolored. In essence, a negative space blackout tattoo is a design that uses empty spaces to create a unique visual effect. Once again, dear Vinglers, thank you sincerely for your love and support for Vingle.Have you ever heard of a negative space blackout tattoo? If not, you might be wondering what it is and how it’s different from other types of tattoos. We ardently hope to overcome these challenging times together and await the day we reunite with each one of you. With hopes that when the frosty economic climate improves, we wish to preserve the possibility of awakening from this hibernation and eagerly resuming our journey.

Instead of delivering a service that might not meet the expectations of our beloved Vinglers, we've decided to temporarily halt operations to reassess our situation and seek better solutions. During our preparation for the service transition, various issues arose. We announce a temporary suspension of Vingle's services effective from August 25, 2023, at 00:00 hours. First and foremost, we extend my heartfelt gratitude for the unwavering love and support you have given to Vingle over an extended period. You may obtain up to 20 defense with metal armors Platinum armor, but the resources required are better spent elsewhere. The following listings are in rough order of decreasing viability.Īt this point, armor serves little purpose other than to boost your defense. Those who are unwilling to invest fully in defense are advised to focus more on damage or critical hit bonuses. While it is unlikely to make you invincible, boosting defense as high as possible is a legitimate strategy even on higher difficulties. Your actual mobility mainly comes from Wings, which do not benefit from these bonuses.ĭefense is a polarizing stat whose effectiveness largely depends on what enemies you plan to tank hits from, and becomes disproportionately more potent when your defense is already very high. Also, movement speed bonuses granted by armor pale in comparison to the +85% movement speed granted by Exquisitely Stuffed, Slice of Cake, and Swiftness Potion.
However, a Plugable product based on DisplayLink USB video technology can allow additional monitors to be used once the required DisplayLink Manager Application is installed.įor example, you could connect a Plugable UD-3900 docking station which is based on DisplayLink technology to the MacBook Air (M1, 2020) model laptop which would allow you to connect two external monitors to the Mac. According to Apple, that particular model is limited to one external monitor. Let’s go back to our earlier example of MacBook Air (M1, 2020) model laptop. The answer is that Plugable makes products that can circumvent the ‘out of the box’ limitations in regard to how many external monitors can be connected to a Mac laptop with an Apple M1 processor. Now that we understand how many external monitors can be connected to Mac laptops with an Apple M1 processor, where do Plugable products come in? The information under the ‘Display Support’ section is more complex as compared to the previous example, because this particular model Mac can have either an ‘M1 Pro’ or an ‘M1 Max’ processor and number of external monitors supported can vary depending on the processor model. Where things can get a little more complicated is when you ‘step up’ to a Mac laptop that has either the ‘M1 Pro’ or the ‘M1 Max’ processor as opposed to just the plain ‘M1’ processor.įor example, the specifications page for the MacBook Pro (16-inch, 2021) model laptop has a section named ‘Display Support’. However, these details can be easy to miss if you are not looking for them and in some cases the information can be slightly confusing.įor example, the specifications page for the MacBook Air (M1, 2020) model laptop has a section named ‘Video Support’ which states that one external monitor is supported, which is of course fairly straightforward. The one aspect of Apple’s change to M1 processors that we would like to focus on in this blog post is the number of external monitors that Apple supports ‘out of the box’ with a Mac with an M1 processor.Īs of this writing, Apple makes Mac laptops that can have one of three different versions of the Apple M1 processor.Īpple Mac laptops with an Apple M1 processor can support a maximum of one external monitor.Īpple Mac laptops with an Apple M1 Pro processor can support a maximum of two external monitors.Īpple Mac laptops with an Apple M1 Max processor can support a maximum of four external monitors.Īpple does call out these capabilities in the technical specifications for the various Mac laptop models. The switch to M1 processors for Mac systems from the previous Intel processors was a dramatic change which brought many improvements in terms of both performance and power efficiency. Given the capabilities of our products, one of the most common questions we get from potential customers is, “How many external monitors can I add to my Mac that has an Apple M1 processor?”įor those that may not be aware, in 2020 Apple introduced the first Macs based on Apple’s own M1 processors. At Plugable, we make a lot of different products that allow you to add external monitors to your Mac. |
