If there are top ten buzzwords in the technology industry in the year 2019, the container is sure to be one of them. With the popularity of Docker, more and more scenarios are using Docker in the front-end field. This article shows how do we use Docker in the visualization interface of Nebula Graph, a distributed open-source graph database.

Why Using Docker

Docker is widely used in daily front-end development. Nebula Graph Studio (A visualization tool for Nebula Graph) uses Docker based on the following considerations:

With billions of internet users worldwide spending several hours online each day, the online presence of brands is now a necessary avenue for building, boosting, and maintaining positive value and attracting and interacting with customers. 

This has created increasing pressure for web design agencies when creating and managing websites. This pressure is multiplied by all the projects that web design agencies have to handle at one time. This is because different clients demand different things for their websites, whether it’s a signature feature or specialized functionality. 

Hence, it’s vital that the tools the agencies use to work are simple enough and suited to the tasks they have to accomplish in order to build and maintain these projects. Having the right tools can increase efficiency and effectiveness in managing websites.

Challenges in Modern Web Design

Building a website with all the essentials in mind is always easier said than done. Websites have to be both functional and easy on the eyes to invite traffic, disseminate information, or appeal a product or service to a target audience, and all while having an attractive and convenient interface.

The good news is that it’s perfectly possible to design a quality website and without spending a fortune to do so. Below are some of the challenges that web design agencies face when trying to deliver and reconcile efficient user experience and effective user interface in web design.

1. Appealing User Experience

Designing a good website means ensuring that the user experience is appealing to a general audience, but this is one of the most difficult parts of web design. Agencies must be careful not to turn off users with a confusing user experience. For instance, making important information difficult to find on web pages, using technical jargon that ordinary users wouldn’t understand, and focusing too much on the design rather than the overall experience are a few big mistakes that no designer should ever commit.

Instead, web design agencies should focus not only on making the design look good but also on making the experience smooth and fast for the regular site visitor. This includes improving design elements to make navigation easier as well as optimizing webpage load speeds.

2. Working With a Budget

It’s common for the client and the web design agency’s budgets to not line up at all times. Either the client will find the project quote too high, or the designer will find the client’s budget too low. The cost of a web design project can vary greatly, depending on what needs to be done. 

Although having to build a good website on a budget may be difficult, it’s important for both parties to come up with a set amount before the project even starts. The client should always specify what they want to achieve and how much they’re willing to pay to get it, and the agency should let the client know beforehand if this is possible.

3. Integrating Third-Party Functionality

Sometimes, clients may make requests for third-party functions that may not be easily integrated into the site. To prevent this, web design agencies should always consider integration when building a site. Most businesses and companies now have at least one social media account, so it doesn’t make sense for their site to remain disconnected.

When a website visitor shares an excerpt on a social media site like Facebook, Pinterest, or Twitter, other people who can see their posts may become interested in visiting the original post on the website. Properly integrating third-party applications and functions into a website can get it more online presence and popularity.

4. Suitability to Different Devices

There are many devices that people can use to access the web. From smartphones to desktop computers, from cars to game consoles, and even wristwatches and digital cameras, all of these can be web-enabled as long as there’s an available internet connection. 

Websites nowadays should always be compatible with any of the devices people might use to go to the website. They should look pleasing and load fast regardless of what device a visitor is using.

5. Security of Personal Information

Most websites require personal or financial information, whether for account verification, for website subscription, or something else. Websites should be designed with personal security in mind, which is even more important since hacking has been on the rise since the coronavirus hit.

One of the biggest threats that websites face today is phishing, or when an attacker will pretend to be a trusted contact and attempt to compel you to click a malicious link. Another is ransomware, or where cybercriminals hold customer data for ransom and attempt to extort online business owners. Yet one more is SQL injections, or where hackers will attempt to execute malicious SQL commands in your website’s database. 

The best practices in regards to web design to mitigate these risks include third-party plugins and themes, keeping all of your software up to date, setting your web applications so they run the fewest privileges possible, and utilizing SSL certificates and HTTPS protocols. 

Adopting Site-Building Platforms

Gone are the days where you had to be technologically gifted to design a website from scratch, usually through manual HTML codes. Back then, you had to know your way around the web if you wanted to set-up and manage a site of your own.

Now, there are a lot of good website builders that allow you to create websites in a faster period of time. Even web design agencies now make use of such builders in order to make the job easier and more convenient. Not to mention, it allows agencies to focus on the design alone.

Although these platforms offer predesigned templates based on the most common purposes of websites, they normally allow the user to white label the website into the branding specific to the business or agenda of the website owner. The text styles, colors, and sizes coordinated to the website’s theme, and colors can be designed specifically to match the business or organization’s image and identity. 

Simply put, creating websites through a web builder platform can provide web design agencies with easy-to-understand tools that their teams and members can all uniformly use to more effectively and more efficiently handle all their projects.

With services that allow mobile optimization, site management, and even drag-and-drop editing, web design agencies can now better manage their projects and finish with their tasks more quickly.

Not only that, by using white labelling, services can conserve their time and energy into focusing on creating the best website for their client. With all the website builders currently available on the market today, just picking the right one can give web design agencies the best tools to use when creating, designing, and maintaining websites.

Normally when we create an HTTP REST endpoint, we add code to our server endpoint, and assume the client provides the arguments to our code. What if we could reverse this responsibility, such that the client provides the code the server executes?

Among other things, this implies we can have one endpoint doing "everything". We wouldn’t need to create dozens of endpoints to expose our API, and we could get away with creating a single endpoint, that clients invokes, regardless of what they want to do. If the client wants to create a record in our database, read records from our database, or count records in our database is irrelevant – He’d still use the same endpoint for all of these tasks. In addition, the client could become much more creative in regards to how he interacts with our API, and do things we couldn’t even imagine as we created our API. The latter of course sums up the problem, which is that clients could inject malicious code into our server.

And it does this 24 hours a day, 7 days a week, 52 weeks a year without ever asking for a pay raise.

But this is true only if your website landing page is designed well, maintained, and optimized to the gills. The art and science of a flawless landing page is beyond the scope of a single article, but we can start with helping you spot seven of the most common – and damaging – trouble spots.

1. Unclear Value Statement

Typically, new visitors to your page will only stay on it 3 to 15 seconds before they get distracted. In that span of time, you must offer a clear and visible reason to stick around and interact with the page.

That reason is your value statement. What value do your readers get in exchange for the time you ask them to spend? High-quality content is a must (and hopefully a given), but you also need to pull them in so they experience that content.

Does your landing page do that? If yes, great! If no, you should fix that. If you’re not sure, ask yourself:

  • Is there a compelling, visible headline that expresses the end benefits clearly and succinctly?
  • Is there a subheadline explaining your offering in more detail?
  • Are there supporting graphics that pull the eye toward your headline and subheadline?

If there aren’t, add them now.

2. Poor Signposting

Your landing page isn’t just there to be pretty. It’s meant to convince people to take action. If you don’t make it easy to find your call to action, most viewers won’t look for it.

deliver enough value to make it worth the hassle

You must make it clear — in as succinct and efficient terms as possible — why the action you want a reader to take will deliver enough value to make it worth the hassle. Tell them, in words that stand out from the rest of the page, what you want them to do next and what they’ll receive for doing so.

Improving your signposting stats by asking yourself the following questions:

  • Do you have a clear understanding of what the next step in a visitor’s customer journey should be?
  • Is it easy to find and take that step on your website?
  • Does your copy make a clear and compelling argument in favor of taking that step?

If you can answer yes to all three questions, your signposting is likely good (or at least good enough for now). If not, now you know what you have to do to improve it.

3. Slow Loading Time

Remember that 3 to 15-second maximum time limit we mentioned earlier? That span includes time spent waiting for your landing page to load, and every microsecond of that wait increases a reader’s likelihood of bailing on the whole thing. You must get your loading time to be as quick as possible.

Viewers who exit your landing page early – including while still waiting for it to load – increase your site’s bounce rate. Higher bounce rates reduce your rankings on Google and other search engines, meaning a page that loads too slowly not only impresses fewer viewers, but it also gets fewer viewers overall.

Improving your loading time is usually a job for your tech team or whoever in the office is responsible for overseeing your hosting service. That said, here are a few of the most important ways to optimize this important factor:

  • Optimize image size, file format, and compression;
  • Clean up your database by deleting saved drafts, old revisions, unused plugins, and similar virtual detritus;
  • Confirm that your WordPress theme (if applicable) is optimized for quick loading;
  • Use a content distribution network for file storage;
  • Analyze server response time with your hosting service, and work with them to reduce it;
  • Install tools that leverage browser caching;
  • Fix all your broken links;
  • Remove all render-blocking from JavaScript;
  • Reduce the number of redirects necessary to reach your page;
  • Optimize your code, especially in CSS, JavaScript, and HTML;
  • Enable file compression — except for on images;
  • Replace all PHP content with HTML wherever possible.

This is technical, detailed work, but it’s important. If you don’t have team members up to these tasks, it can be worth hiring an outside consulting company to do it for you.

4. Only One Landing Page

You have a good idea of your ideal customer’s hopes, fears, pain points, demographics, likes and dislikes, and other important information. If you have several different types of customers, you can’t use the same landing page for each of your customer groups. Each group has different characteristics that will prompt them to follow your call to action, so you don’t want to offer just one landing page.

Similarly, you also probably have more than one product or set of content and offerings to generate sales. Having only one landing page can lose leads because the page is only optimized for one of those products or content sets.

Ideally, you should have a unique landing page with a tailored offer for each of your customer models that would send those individuals to each of the products and content sets. An ad for professionals in their 30s making over $50,000 a year would lead to a landing page built for them, while an ad for heads of households working from home would lead to a landing page built for them.

Yes, that means a company with three profiles and four content sets would need 12 landing pages. And yes, it’s worth that kind of effort.

5. Insufficient Visuals

“A picture is worth 1,000 words” is ancient wisdom, but it’s far from true in the internet world – it’s actually worth more. A quick look at social media and blog performance will tell you many people will look at, enjoy, and share a photo or video, but not many will read an entire 1,000-word post on the same topic.

How well your landing page performs depends on the images you use and how you present them. Does your page’s layout conform to the best practices of visual web design:

  • Including images that emotionally reinforce the value expressions of your product’s core benefits;
  • Containing sufficient white space to not be intimidating;
  • Providing data images to indicate the worth of what you do;
  • Using visual design cues to lead the eye toward your conversion points;
  • Applying color gradients to highlight offers and your call to action;
  • Using infographics to replace the dreaded “wall of text”.

If you can say yes for half of these things, carry on. If not, this point may be among the better places to start with a landing page redesign.

6. Asking For Too Much, Too Soon

Craft a custom calls to action that meet all levels of interest, need, and desire

Not every landing page visitor is created equal. Some are hardcore fans and experts in what you do, ready for a 10,000-word white paper that dives deeply into the research supporting your use case. Others might have heard about your industry on an Instagram page and want to know the basics of what you do.

There’s nothing worse than going to a website and being asked for all of your personal information right away. If your call to action requires too much knowledge, too deep a commitment, or even too much personal information, consider scaling back. Otherwise, you risk turning away potential customers.

Better yet, go back to No. 5 above and build a new landing page for beginners and early-stage leads. Craft a custom calls to action that meet all levels of interest, need, and desire.

7. No Trust Elements

Offering some type of authentic customer referral or testimonial is important. It all boils down to the same thing: telling those who read your landing page that other people already like what you do and how you do it.

Examples of effective modern trust elements include:

  • Quotes from positive reviews next to a photo of the reviewer;
  • Screenshots of social media posts praising your company or product;
  • Short video interviews of happy clients;
  • Blurbs for industry thought leaders approving of you;
  • Images portraying business credentials and certifications;
  • Links to positive press coverage;
  • Logos of known business customers who buy and trust your brand.

Final Thought: What’s Next?

There isn’t one guaranteed way to turn a landing page from something full of holes into something perfect. But first, run an audit of your landing page using this list as a guide. Note which errors are there. Next, sort them in order of what takes the least time to fix to what takes the most time to fix.

Then, fix them in that order. We find that getting the quick fixes done builds excitement and momentum, whereas starting with a harder fix can mire down the whole process.

If none of these errors exist on your landing page, congratulations. There’s still lots of work to do on your website and content marketing, but it’s not among these rookie mistakes.

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.

Prologue

In a previous post, I showed how to automate a PostgreSQL fault-tolerant cluster with Vagrant and Ansible.

This kind of setup makes our database cluster resilient to server failure and keeps the data available with no need for human interaction. But what about the apps using this database? Are they fault-tolerant too?

Hyper implies web, and lambda implies function – Hence, Hyperlambda translates into "web functions", and this is a fairly accurate description. However, hyper also implies "super fast", and by super fast here, I mean super fast! 1 minute and 45 seconds was what I needed to create CRUD endpoints wrapping my database table, manually creating my endpoints in the following video, while explaining how I did it simultaneously.

According to modern studies in the subject, the number of lines of code your project consists of, is directly proportional to the amount of energy and resources you’ll need to spend maintaining it. Hence, the fewer lines of code, the fewer resources are required to maintain it. In the video above, I copy and paste 50 lines of code, and I end up with 4 HTTP REST CRUD endpoints. Comparing this to C# is arguably unfair. Simply the boiler plate code for my Controller, would probably end up exceeding this number. You can find my code for all endpoints below.
