This article mainly introduces how to migrate your data from Neo4j to Nebula Graph with Nebula Graph Exchange (or Exchange for short), a data migration tool backed by the Nebula Graph team. Before introducing how to import data, let’s first take a look at how data migration is implemented inside Nebula Graph.

Data Processing in Nebula Graph Exchange

The name of our data migration tool is Nebula Graph Exchange. It uses Spark as the import platform to support huge dataset import and ensure performance. The DataFrame, a distributed collection of data organized into named columns, provided by Spark supports a wide array of data sources. With DataFrame, to add new data source, you only need to provide the code for the configuration file to read and the Reader type returned by the DataFrame.

On-call: you may see it as a necessary evil. When fast incident response can make or break your reputation, designating people across the team to be ready to react at all hours of the day is a necessity.  But, this often creates immense stress while eating into personal lives. It isn’t a surprise that many engineers have horror stories about the difficulty of carrying a pager.

But does on-call have to be so dreadful? No way. Here are five best practices to help your team respond quicker and build more resilient systems.

It’s fun to see new website design tools that reflect current times and the state of the world. That’s very true this month with new databases devoted to diversity and women in technology, as well and resources to make your design life easier.

Here’s what’s new for designers and developers this month:

Ztext.js

Ztext.js is an easy to implement, three-dimensional typography tool for the web that works with any font you want to use. With the popularity of 3D effects and animation, this tool has a lot of practical applications. Everything you need, including documentation, is available from developer Bennett Feely on his website and GitHub. (It’s free but you can show appreciation with a donation if you like it.)

Gradient Magic

Gradient Magic is a free gallery of fun and interesting CSS gradients. You can sort through a random selection or by category of color to find just the right gradient for your project. Some of them would make really neat backgrounds or image overlays.

Impossible Checkbox

Impossible Checkbox is a fun little divot that you’ll want to play with and emulate. Click or tap the slider to activate and a nifty little friend pops up. Now here’s the fun part: You can’t leave it checked, and take note of the changing expression of the checkbox character.

Diversify Tech

Diversify Tech isn’t your average job board; it is a collection of resources – and opportunities – for underrepresented people in technology. It includes a weekly roundup and everything from scholarships, to events, to jobs, to speaking opportunities.

Women in Tech

Women in Tech is a list of apps made by women. The apps are ranked and chosen based on upvotes and is a good resource if you want to help support women-owned projects. Search or submit an app for inclusion.

Devello Studio

Devello Studio is a tool that allows you to write code in the cloud. You don’t have to install anything and no matter where you are, just can open a project in-browser, and continue development where you had left off last time. Plus, it works with GitHub support built right in.

Hustl

I quote the title from the book Mythical Man-Month written by Fred Brooks and originated from Theodore von Kármán in the unique form “Everyone knows it takes a woman nine months to have a baby. But you Americans think if you get nine women pregnant, you can have a baby in a month.” Fred Brooks made this a very popular statement in the software industry, with good reasons. The idea behind it is that adding manpower to a late software project makes it later, also called Brooks’ Law.

This is a story about where I have seen this happen and what the result became to be.

Stack ranking is natural human behavior 

I have a buddy from high school named Murph. His real name is Ben Felt but every legit teenage crew in Pitsford, New York in the 90s needed a Murph so Ben took one for the team.

He’s a quant. Like Taylor Mason from the show Billions.

In this time of global economic turmoil, it’s more important than it’s ever been that your financial decisions are based on accurate, up-to-date, market information.

In a world where stock price is a key confidence marker, the businesses that attract attention, secure investment, and grow, are the ones that can demonstrate their value in a wider market.

Up to now, displaying accurate market pricing has been prohibitively expensive, needing direct access to a huge dataset, and the code to mine it. So we’re delighted to introduce marketstack, a real-time market data API that’s reliable, simple to integrate with your site or app, is lightning fast, and includes a free-forever plan.

What is marketstack?

marketstack is a REST API that allows you to access stock data for public companies at 72 global exchanges including the New York Stock Exchange, the Nasdaq, the Tokyo Stock Exchange, and the London Stock Exchange.

marketstack delivers real-time market data, accurate to a single minute, ensuring that the information you base your decisions on, and the information you pass on to your customers, is always up to date.

There are more than 125,000 stock tickers, from over 50 different countries; you can query stocks, or over 75 different market indices; intraday market data is included, meaning you can monitor trades that close at the end of the day; you can even retrieve data about time-zones and international currencies.

Why Choose marketstack

marketstack uses cutting-edge technology to deliver market data in an easy-to-integrate JSON format, which is lightweight and incredibly easy to dig into.

Requests are made via a simple HTTP GET call, and all requests are run through bank-quality 256-bit HTTPS encryption. Whatever code stack you’re using, whether it’s PHP, Python, Node, or plain old JavaScript, marketstack provides comprehensive documentation to get your team up to speed in mere minutes.

The highly reliable cloud infrastructure can handle anything from a few dozen requests per year, all the way up to millions of requests per day. Regardless of the scale of your project, marketstack is robust and flexible enough to handle it.

It’s Not Just About Money

marketstack isn’t just about the bulls and bears of markets, in the tech sector specifically, stock price is an indicator of wider business trends and performance.

When Apple became the first US company to reach a $2 trillion valuation, not only was its stock price central to the story, but it indicated a trend in the tech giant’s dominance that went beyond cold hard cash.

When an eccentric billionaire makes outrageous, and ill-judged comments, and tanks his company’s valuation, the fluctuations in stock price are a big part of the story.

Beyond the spin of politicians, the market index of different exchanges is an indication of what analysts with in-depth knowledge really think during an election campaign.

With over 30 years of historical data, marketstack is a history of business, particularly the burgeoning tech sector, and makes that history available with a simple to use API.

marketstack’s Rock Solid API

marketstack’s API is built on top of apilayer technology, one of the most respected, and trusted API providers in the world, with a huge amount of experience delivering data reliably. Millions of API requests can be run through the API hourly, and it still has almost 100% uptime.

Any API is only as good as the data it supplies, and marketstack’s data is supplied by numerous high-authority providers around the globe, resulting in unprecedented accuracy.

As a result, marketstack is trusted by over 30,000 companies — including Microsoft, Amazon, Uber, and Credit Suisse — and 80+ universities.

Getting Started with marketstack

marketstack is entirely free for up to 1000 requests per month, with access to 1 year of historical data, as well as end-of-day data. No credit card is required to get started, and you’ll never be billed. This is the perfect option for simple integrations, or developers working on proof-of-concept builds. What we really like about marketstack is that the free package is genuinely usable. It’s not just a trial version that presses you into upgrading.

For anyone who needs more comprehensive data, packages that include market indices, technical support, and commercial use permissions, start at $9.99 per month, or just $7.99 per month when billed annually.

Head over the marketstack today to claim your free API key, and get started.

To understand why user onboarding is such an indispensable tool, we need to empathize with the people using our products; we all come from different backgrounds and cultures, we make different assumptions, and we see the world differently.

User onboarding helps mitigate these differences by making your product’s learning curve less steep.

However, companies often make unfortunate mistakes that hinder user experience and cause frustration. In today’s article, we’ll take a look at eight ways companies ruin their products’ onboarding process.

Let’s dive right in, shall we?

1. No User Onboarding at all

As a part of the team that created a product, you’ve probably spent hundreds of hours going over its features and the most minute detail. Naturally, you know the product like the back of your hand. The user does not.

Naturally, you know the product like the back of your hand. The user does not

We may believe that the app we’ve worked on is straightforward and that user onboarding is probably overkill — but that’s almost never the case. Guiding our users through a product will help with retention, conversion, and their overall satisfaction.

However, there are very rare cases when you can do without user onboarding, here are a few:

  • Your product is too straightforward to cause any confusion;
  • Your product has a formulaic structure, similar to that of other products’ in your category, i.e., social media or e-commerce;
  • Your product relies heavily on Google or iOS design guidelines with common design patterns;
  • Your product is too complex (enterprise or business-oriented) — in such cases, users need special training, rather than just an onboarding;

2. Assuming That Users “Get It”

 One of the vital UX mottos we should always be mindful of is that “we are not our users.” When onboarding them, we always need to assume that they’re at square one. We should communicate with them as if they have no prior knowledge of our product, its terminology, and the way it works.

Providing freshly-registered users with highly contextual information will most likely confuse them. As a result, this will render your attempts to create a helpful onboarding process useless.  

3. Onboarding Users on a Single Touchpoint

it’s tempting to brainstorm which features should make it into the onboarding, then design and code them; that’s a very bad idea

The main problem with the previous point is that it’s too contextual for new users. However, providing no context altogether can be problematic as well. This is commonly found in onboarding processes that focus on a single touchpoint while leaving out the rest of the product.

By choosing to inform users of our product’s features, we force them to detour from their “normal” course of action. This comes at the cost of the user’s frustration.

Since we’re asking people to pay this price, it’s best to provide them with information that will also help them navigate the entire product. As a result, this will decrease the number of times we’ll have to distract them from their ordinary flow.

4. Forcing Users Through Onboarding

We’ve previously mentioned that we mustn’t assume that users have any background knowledge about our products.

The opposite argument can be made — experienced users don’t need a basic onboarding process. It will most likely frustrate them, and it won’t provide them with any real value. Also, forcing users through this process will most likely take the onboarding frustration to a whole other level.

This is why it’s essential that we allow them to skip the parts they don’t find useful. This way, we’ll address the knowledge gaps of the people who really want it and need it.

5. Onboarding Based Purely on Assumptions

This is yet another point that’s implicit in “we are not our users”. Oftentimes, it’s tempting to brainstorm which features should make it into the onboarding, then design and code them; that’s a very bad idea.

Here’s what every designer should do instead:

  • Do user interviews: You should conduct these before having anything designed; user interviews will help you shortlist and prioritize features in terms of their significance, so that the onboarding is focused around the features that matter most.
  • Do usability testing: Once you have a good idea of what features your users consider most important, design onboarding that reflects that; having completed your design, make sure to conduct at least 5 usability testing sessions with users, so that you can make sure that your design works.

6. Just Letting Users Quit

While we shouldn’t force people to go through onboarding, it doesn’t mean we shouldn’t nudge them in the right direction.

find that sweet spot between being front of mind and annoying

People choose not to onboard for many reasons, but showing them around will benefit both parties. Therefore, it’s never wrong to remind them that they can always resume onboarding via email or push notifications (unless you’re too pushy). Make sure to find that sweet spot between being front of mind and annoying. 

Similarly, these two mediums are a great way to deliver valuable information as well.

Here’s a great example of an onboarding email from InVision:

7. Asking For Too Much Information

We need to always be mindful of the fact that the product’s spokesperson should act as a guide during onboarding. Its goal at the very beginning is to build trust.

We can ask for small favors when we’ve built a solid and lasting relationship

Not only is asking for too much information from the get-go unproductive, but it will also undermine the trust that the user already gave us.

It’s best to abstain from asking freshly-registered users for their credit card information. Nearly 100% of businesses care about profits — and there’s no shame in it. However, today’s most successful companies make money by providing users with value. So it’s best to stimulate users to share their financial data in subtler ways while focusing on customer experience.

The same can be said about subjecting the people using your service to extensive questionnaires. At the first steps of our interaction, it’s all about giving and gaining trust. We can ask for small favors when we’ve built a solid and lasting relationship.

8. Onboarding for the Sake of Onboarding

While there are dozens of reasons why you should guide your users through your product, it needs to be done well. A pointless onboarding process that doesn’t provide users with value is more frustrating than the lack thereof.

Onboarding can be a bit frustrating at times. Pointless onboarding will just raise eyebrows. It will slow users down and disengage them, which is exactly the opposite of what we want.

Conclusion

The process of introducing your users to your product is one of the factors that will define its success.

A critical aspect of user onboarding that we need to always take into account is value. Is this detour from our user’s ordinary course of action valuable to them? Will this improve their experience with the product?

Onboarding demands careful and continuous tailoring. Once perfected, this process will help you win new users’ hearts and help you build brand loyalty.

Google resembles an iceberg: there’s the part above the water we can see and use everyday; there’s also the part beneath the water, that we don’t see and know little about.

While many of us are concerned about the aspects of Google we don’t see — the parts that threaten our privacy, or monopolize the web — there’s no denying that Google offers some amazing products and tools, many of them free, all from the convenience of a single login.

Today we’re going to take a look at 12 tools from Google that really do bring something positive to the table.

1. Polymer

Polymer is an open-source JavaScript library from Google for building web applications using Web Components. The platform comes with a ton of libraries and tools to help designers and developers unlock the web’s potential by taking advantage of features like HTTP/2, Web Components, and Service Workers. 

The main feature of Polymer is Web Components. With Web Components, you can share custom elements to any site, work seamlessly with any browser’s built-in elements, and effectively use frameworks of all kinds. Products like LitElement (a simple base class for creating fast, lightweight web components) and PWA Starter Kit make Polymer easy to use. If you like, you can build your app entirely out of Web Components.

2. Lighthouse

Google Lighthouse is an open-source, automated tool for improving the quality of web pages. The software allows you to audit web pages for performance, SEO, accessibility, and more. You can run Lighthouse using ChromeDevTools, directly from the command line, or as a Node module. 

To use Lighthouse in Google Chrome, just go to the URL you want to audit (you can audit any URL on the web), open ChromeDevTools, and click the Audits tab. After you have run the audit, Lighthouse will give you an in-depth report on the web page. 

With these reports, you will see which parts of your web page you need to optimize. Each report has a reference doc that explains why that audit is important and also shows you the steps you can take to fix it. 

You can also use Lighthouse CL to prevent regression on your sites. Using Lighthouse Viewer, you can view and share reports online. You can also share reports as JSON or GitHub Gists. 

Lighthouse also comes with a feature called Stack Packs that allows Lighthouse to detect what platform a site is built on. It also displays specific stack-based recommendations.

3. Google Analytics

Google Analytics is the gold standard of analytics services. Google analytics can be installed on your site for free with a small amount of JavaScript and allows you to see all kinds of details about your site visitors, like what browser they’re using, and where they’re from.

By using Google Analytics you can make decisions about your site based on science, and therefore be somewhat confident that the decisions you make will result in the outcome you are expecting.

4. Flutter

Flutter is Google’s UI toolkit for building natively compiled applications for mobile, web, and desktop from a single codebase. The toolkit is open source and free to use. The best part of Flutter is that it works with existing code. 

The toolkit has a layered architecture that allows for full customization, which results in fast rendering and flexible designs. It also comes with fully-customizable widgets that allow you to build native interfaces in minutes. With these widgets, you will be able to add platform features such as scrolling, navigation, icons, and fonts to provide a full native performance on both iOS and Android.

Flutter also has a feature called hot reload that allows you to easily build UIs, add new features, and fix bugs faster. You can also compile Flutter code to native ARM machine code using Dart native compilers. 

5. Google API Explorer

Google has a huge library of APIs that are available to developers but finding these APIs can be difficult. Google API Explorer makes it easy for developers to locate any API. On the Google API Explorer web page, you will see a complete list of the entire API library. You can easily scroll through the list or use the search box to filter through the API list. 

The best part of Google API Explorer is that each link to a reference page comes with more details on how to use the API. API Explorer is an excellent way to try out methods in the Monitoring API without having to write any code.

6. Puppeteer

Puppeteer is a project from the Google Chrome team. The platform enables web developers to control a Chrome (or any other Chrome DevTools Protocol based browser) and execute common actions, much like in a real browser. Puppeteer is also a Node library and it provides a high-level API for working with headless Chrome. It is also a useful tool for scraping, testing, and automating web pages. 

Here are some things you can do with Puppeteer: generate screenshots and PDFs of pages, UI testing, test Chrome Extensions, automate form submission, generate pre-rendered content, and crawl Single-Page Applications. 

7. Codelabs

Google Developer Codelabs is a handy tool for beginner developers and even advanced developers who want to improve their knowledge. Codelabs provide a guided, tutorial, hands-on coding experience. Codelabs’ site is broken down into several tutorial sessions on different topics. 

With the tutorials on Codelabs, you can learn how to build applications from scratch. Some of the tutorial categories include Augmented reality, TensorFlow, Analytics, Virtual Analytics, G Suite, Search, Google Compute Engine, and Google APIs on iOS. 

8. Color Tool

Color Tool makes it easy for web designers to create, share, and apply colors to their UI. It also measures the accessibility level for any color combination before exporting to the palette. The tool comes with 6 user interfaces and offers over 250 colors to choose from. 

The tool is also very easy to use. All you need to do is pick a color and apply it to the primary color scheme; switch to the secondary color scheme, and pick another color. You can also switch to Custom to pick your own colors. After you have selected all your colors, use the Accessibility feature to check if all is good before exporting it to your palette. 

9. Workbox

Workbox is a set of JavaScript libraries and Node modules. The JavaScript libraries make it easy to add offline support to web apps. The Node modules make it easy to cache assets and offer other features to help users build Progressive Web Apps. Some of these features include pre-caching, runtime caching, request routing, background sync, debugging, and greater flexibility than sw-precache and sw-toolbox. 

With Workbox, you can add a quick rule that enables you to cache Google fonts, images, JavaScript, and CSS files. Caching these files will make your web page to run faster and also consume less storage. You can also pre-cache your files in your web app using their CLI, Node module, or webpack plugin. 

10. PageSpeed Insights

PageSpeed Insights is a handy tool from Google Developers that analyzes the content of a web page, then generates suggestions on how to make the page faster. It gives reports on the performance of a web page on both desktop and mobile devices. At the top of the report, PageSpeed Insights provides a score that summarizes the page’s performance. 

11. AMP on Google

AMP pages load faster and also look better than standard HTML pages on mobile devices. AMP on Google allows you to enhance your AMP pages across Google. It is a web component framework that allows you to create user-first websites, ads, emails, and stories. One benefit of AMP is that it allows your web pages to load almost instantly across all devices and platforms hence improving the user’s experience. 

12. Window Resizer

When creating websites, it is important that developers test them for responsive design – this is where Window Resizer comes in. Window Resizer is a Chrome extension that resizes the browser window so that you can test your responsive design on different screen resolutions. The common screen sizes offered are desktop, laptop, and mobile, but you can also add custom screen sizes.
