It compares listed prices from Amazon and Google, recommends buying only the domain and using Cloudflare for DDoS protection, and explains creating an A record and verifying the resulting IP address. ### Source excerpt So I needed to register a .IO domain today. Amazon had .io domains at $71 per and Google had them at $60. A quick check with my guru of cheapness, Nick Janetakis, said: NameSilo.com And he convinced me. Here are some tips: Do not accept any of their options. Just the domain, Sir, just the domain. Use DDOS protection from CloudFlare instead of their option. CloudFlare is free. Once you are registered then the option you likely need is to create an A record. This is done by selecting the domain from the Domain Manager view and then clicking the blue icon. Amazon is way prettier but double the price is a hard sell. After you create it, wait some period of time and ping it. Verify the ip address is yours.

It demonstrates generating a project with cargo new, describes the Cargo.toml package manifest and dependencies, and shows the initial src/main.rs Hello World program. ### Source excerpt The Rust tool cargo is the Rust equivalent of rake and bundler and rails combined (these are Ruby tools). Cargo is what you use to generate a new Rust app. Here's an example: cargo new loader_datastreamer_to_kafka_rust This generates a new, correctly laid out project directory. And here's what it looks like: ❯ tree . ├── Cargo.toml └── src └── main.rs 1 directory, 2 files The Cargo.toml file is a package manifest which has a default contents of this: ❯ cat Cargo.toml [package] name = "loader_datastreamer_to_kafka_rust1" version = "0.1.0" authors = ["Scott Johnson "] edition = "2018" # See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html [dependencies] Any Rust packages, which are named crates, you use in your application would be listed under the dependencies section. Here's an example of that: [dependencies] notify = "4.0.15" That's an example of using the notify crate. Your default main.rs file is always stored in src and looks like this initially: ❯ cat src/main.rs fn main() { println!("Hello, world!"); } Yep - you get a Hello World for free when you create any Rust application. Cargo actually does quite a bit more than just creating your Rust application but that's a topic for another day. ## Let's Build A Simple Interpreter.

Using a Rails console example with Book and BoardGame subclasses of Item, it demonstrates failed attribute assignments, leftover attributes, and incorrect validators caused by the in-memory object retaining its previous type. ### Source excerpt I recently faced some issues when trying to update a nested document's type via nested attributes using the mongoid gem. Bare with me if this sentence doesn't make any sense yet. Use case Suppose we have a document named Person that embeds a document that can be any of the types Book or BoardGame which inherit from the class Item. Item class Item include Mongoid::Document embedded_in :person, inverse_of: :item field :name end Book class Book < Item field :authors, type: Array end BoardGame class BoardGame < Item field :players, type: Integer end Person class Person include Mongoid::Document embeds_one :item, inverse_of: :person accepts_nested_attributes_for :item, allow_destroy: true end The problems To simplify the post I won't go with the scenario of building the forms and the controller actions to demonstrate the problems but instead I will simulate the behavior in the rails console. Let's create a Person with a Book as an Item. >> person = Person.create!({ item_attributes: { _type: "Book", name: "Jitterbug Perfume", authors: ["Tom Robbins"] } }) => # >> person.item => # Failing attribute assignments Let's try to change the person's item from Book to BoardGame with 5 players. >> person.update_attributes({ item_attributes: { _type: "BoardGame", name: "Ticket to Ride", players: 5 } }) Traceback (most recent call last): 1: from (irb):9 Mongoid::Errors::UnknownAttribute () message: Attempted to set a value for 'players' which is not allowed on the model Book. summary: Without including Mongoid::Attributes::Dynamic in your model and the attribute does not already exist in the attributes hash, attempting to call Book#players= for it is not allowed. This is also triggered by passing the attribute to any method that accepts an attributes hash, and is raised instead of getting a NoMethodError. resolution: You can include Mongoid:: ## Setting Up Your Own Image Transform Service DevFeed: [Setting Up Your Own Image Transform Service]() Original publisher: [Read original article]() Author: andrew@nystudio107.com (Andrew Welch) Published: 2019-07-05T15:33:00Z Content type: tutorial Language: en Sources: [nystudio107 | Articles on modern web development.]() Topics: [AWS Lambda](), [Serverless](), [Amazon Web Services](), [modern web development](), [Node.js]() Tags: [aws-lambda](), [build](), [cloudfront](), [cloudinary](), [compression](), [create](), [handler](), [hosting](), [image](), [images](), [insights](), [lambda](), [leveraging](), [optimized-transformed](), [pennies](), [power](), [serverless]() ### AI overview This tutorial explains how to use AWS Lambda and the AWS Serverless Image Handler, fronted by CloudFront, to offload processor-intensive image transformations from a website server.

It demonstrates defining array-backed tags, creating and querying posts, and contrasts this approach with Django many-to-many relationships. ### Source excerpt A few weeks back I did a brief feature highlight on Postgres arrays. Since that time I've found myself using them with increasing regularity on small side projects. Much of this time I'm using Django and of course not opting to write raw SQL to be able to use arrays. Django actually makes it quite simple to work with Arrays in Postgres with a package by Andrey Antukh. Lets get started by installing two libraries: pip install djorm-ext-pgarray pip install djorm-ext-expressions The first library is for support for the array field type, the second allows us to more easily mix bits of SQL within the Django ORM. Now within our models.py we'll want import the library then we'll have an entirely new field type available to us: from djorm_pgarray.fields import ArrayField from djorm_expressions.models import ExpressionManager class Post(models.Model): subject = models.CharField(max_length=255) content = models.TextField() tags = ArrayField(dbtype="varchar(255)") Now we can begin using this. For example to create a simple blog post: Post(subject='foo', content='bar', tags=['hello','world']) post.save() In this example we're able to tag blog posts as one normally might, without requiring an extra model to join against. Taking advantage of the SQL Expressions library by Andrey as well we can query a blog post contains a certain tag: qs = Posts.objects.where( SqlExpression("tags", "@>", ['postgres', 'django']) ) Now to show some contrast lets take a look at how you would do the same thing without using the Array field: class Tag(models.Model): name = models.CharField(max_length=255) class Post(models.Model): subject = models.CharField(max_length=255) content = models.TextField() tags = models.ManyToManyField(Tag) Using the many-to-many relationship within Django requires you to save the Post, then add your tag is it requires having a primary key first: post = Post(subject='foo', content='bar') post.save() post.tags.add('hello','world') This means we have two calls to save it, an ## Xen - Podstawowe polecenia DevFeed: [Xen - Podstawowe polecenia]() Original publisher: [Read original article]() Author: Tom Published: 2012-06-19T00:00:00Z Content type: tutorial Language: pl Sources: [Tomasz Gągor]() Topics: [Xen](), [LVM]() Tags: [bridge](), [create](), [delete](), [domain](), [example](), [gateway](), [howto](), [image](), [ip](), [lvm](), [memory](), [os](), [power](), [tools](), [uptime](), [xen]() ### AI overview A Polish tutorial explains basic Xen commands for creating and deleting virtual machines and for managing their lifecycle, including listing, starting, shutting down, resetting, restarting, pausing, and monitoring resource usage.
