Why developers must use Golang for software development projects

Go (or Golang) is an open-source programming language initially made by Google that has been acquired in prominence due to its superior, expressiveness and clarity. In this article, we will depict its beginnings, principle highlights, and the benefits it offers both for developers and for organizations. 

 

Origin of Golang 

At the point when Google was developing dramatically, it needed to manage issues of scale. They basically had heaps of everything: a huge number of designers, loads of programming and frameworks, a great many lines of code (particularly behind their organization servers) being created by many developers, lastly bunches of equipment on which this product was dispatched. 

To make matters significantly more convoluted, the whole source code was put away in a solitary solid vault. While the code was being constructed, it was fundamental to confirm if the progressions presented in one spot didn't bring about different parts not working as expected. 

A tremendous measure of time was expected to construct a particularly immense codebase. To perform such a form, Google made its own form framework to arrange the code on many machines in equal. 

However, in spite of this and numerous other streamlining endeavors, the time expected to assemble specific frameworks arrived at a few dozen minutes in 2007. Given the tremendous scope, creating programming was a lethargic and troublesome cycle. Code gathering (predominantly in C++) kept going excessively long. 

Then again, utilizing strings and memory utilization in C++ and Java to compose simultaneous code was excessively confounded. Developers committed many errors, and the code was frequently not advanced. To utilize simultaneous programming, a developer needed to make many strings that used common memory of a similar interaction. 
 

This was a basic and exquisite arrangement when a program was straightforward and didn't contain various strings. In case there were such a large number of activities hanging tight for outside assets (circle, organization, and so on), as was regularly the situation in a run of the mill network application, a string was left pausing—and eating up assets like RAM and CPUs (for setting exchanging). In the event that a server was handling 10,000 equal associations, the program turned out to be very asset-hungry or resource-hungry. 
 

Golang benefits 

Tired of these entanglements, Googlers Robert Griesemer, Rob Pike, and Ken Thompson made another language that would expand the usefulness of Google designs and permit them to utilize the organization's colossal equipment assets all the more viably (CPUs with many centers, a quick organization and enormous groups for information handling). Since the most generally utilized programming languages at Google were C++ (essentially for servers) and Java/Python (the remainder of the code), this new language should have been like them, so developers could learn it without any problem. In addition, numerous school and college graduates in the US definitely knew C and Java, so it would likewise be simple for them to learn. 

Golang's makers looked to make a statically composed aggregated language that would be as simple to use as progressively composed languages and have a comparative degree of expressiveness (for example brevity as addressed by the number of code lines expected to communicate a given idea). All in all, they needed to consolidate C++ with Java and Python while catching the best elements from every one of them. Therefore, Golang has components from both statically and powerfully composed technologies. 

 

The powerfully composed and deciphered language highlights include: 

  • simplicity
  • expressiveness 
  • comprehensibility 
  • the capacity to run the code rapidly 

Not progressive, Golang essentially joins various elements acquired from other programming dialects like Java, Pascal, or CSP. It doesn't present especially new or progressive functionalities like Rust, however, it takes what is best from different dialects and utilizations it for purposes more practical than scholastic.

 

Why Developers must use Golang?

Go permits you to utilize diverse programming ideal models: 

basic—a software engineer gives bit by bit guidelines to the machine what activities a program  to perform the task; 

practical (support for terminations)— a software engineer can change project conduct by giving code as terminations; 

procedural—altogether not to rehash code, a software engineer can make reusable code pieces like systems and run them on various occasions in a program; 

However, item situated—a further developed method for reusing code than procedural programming; it utilizes polymorphism; Go permits you to utilize just organization rather than legacy, which is generally seen as a benefit. 

It is the software engineer who chooses which worldview to utilize. For little projects, the procedural methodology might be awesome, while for more mind-boggling frameworks, object-arranged programming turns into an unquestionable requirement. 

Golang has magnificent group adaptability. It very well may be utilized both by little groups of software engineers and in enormous undertakings. This is particularly valuable when you don't have a clue how your group's organization will change later on. Python, Ruby, and other powerfully composed languages, then again, are an optimal decision for a group of a couple of developers, as these technologies give moment criticism. With code created for quite a long time by a lot greater group, utilizing progressively composed technologies viably turns into a test—one Golang is famously able to address. 

You can utilize Golang both for high and low-level programming. You can utilize deliberations and polymorphism. You can likewise utilize appropriate code refactorization to advance memory design for information constructions and impact where a compiler will distribute the design. You can utilize significant level channels, however, when superiority is pivotal you can likewise utilize mutexes. 

Since there is no compiler dispatched on the program run (JIT), incorporated code is predictable. This component makes Golang especially valuable for composing elite frameworks that additionally contain the complex rationale. Assuming you need honestly, you can utilize polymorphism and exemplification. In different spots, you can utilize numerous improvements. This is the situation of data set frameworks, middleware programming, and foundation of any sort. Golang was utilized in such ventures as Kubernetes, Docker, Prometheus, or M3. 

Golang is an ideal language to code network servers, particularly web servers and microservices. Go has capacities to help network programming previously incorporated into the standard library. You don't have to utilize structures to make straightforward REST applications (also on account of NodeJS). In the event of more mind-boggling ones, you can utilize progressed HTTP switches (for example gorilla/mux). 

Another significant Golang includes is the means by which its garbage man works. In Java for a long time GC calculations boosted application throughput (for example the number of handled client demands shipped off the Internet server, the measure of handled information, and so on) High throughput will bring about higher latencies. You can stand by longer for garbage or trash to be gathered and eliminate it at one go. This is exceptionally compelling, however can bring about making the application lethargic for a more extended timeframe, in any event, for several seconds on account of huge stacks. On the off chance that the principal objective of the application is to handle client demands shipped off an Internet server, such high dormancy can negatively affect the client experience. 

In Golang, then again, the garbage collector is improved for low idleness from the start. While throughput will be lower, client solicitations will be handled quicker. This makes Golang an optimal answer for Internet servers

Conclusion: So with the number of functions and features as well as the problems that it addresses created by legacy technologies and languages, Go is the ideal solution for the programming and development of IT projects. You can Hire Golang Developer if you are looking to build your site in Golang.

Migrating From Jira Server: Guide, Pros, And Cons

February 15, 2022 marked a significant milestone in Atlassian’s Server EOL (End Of Life) roadmap. This was not the final step. We still have two major milestones ahead of us: end of new app sales in Feb 2023, and end of support in Feb 2024. In simpler words, businesses still have enough time to migrate their Jira Server to one of the two available products – Atlassian Cloud or Atlassian DC. But the clock is ticking. 

Jira Cloud VS Data Center

If we were to go by Atlassian numbers, 95% of their new customers choose cloud. 

“About 80% of Fortune 500 companies have an Atlassian Cloud license. More than 90% of new customers choose cloud first.” – Daniel Scott, Product Marketing Director, Tempo

So that’s settled, right? We are migrating from Server to Cloud? And what about the solution fewer people talk about yet many users rely on – Jira DC? 

Both are viable options and your choice will depend greatly on the needs of your business, your available resources, and operational processes. 

Let’s start by taking a look at the functionality offered by Atlassian Cloud and Atlassian DC.

Pros and cons of Jira Cloud

When talking about pros and cons, there’s always a chance that a competitive advantage for some is a dealbreaker for others. That’s why I decided to talk about pros and cons in matching pairs. 

Pro: Scalability is one of the primary reasons businesses are choosing Jira Cloud. DC is technically also scalable, but you’ll need to scale on your own whereas the cloud version allows for the infrastructure to scale with your business. 

Con: Despite the cloud’s ability to grow with your business, there is still a user limit of 35k users. In addition to that, the costs will grow alongside your needs. New users, licenses, storage, and computing power – all come at an additional cost. So, when your organization reaches a certain size, migrating to Jira DC becomes more cost-efficient.

Pro: Jira takes care of maintenance and support for you.

Con: Your business can suffer from unpredicted downtime. And there are certain security risks.  

Pro: Extra bells and whistles: 

  • Sandbox: Sandbox is a safe environment system admins can use to test applications and integrations before rolling them out to the production environment. 
  • Release tracks: Admins can be more flexible with their product releases as they can access batch and control cloud releases. This means they’ll have much more time to test existing configurations and workflows against a new update. 
  • Insight Discovery: More data means more ways you can impact your business or product in a positive, meaningful way. 
  • Team Calendars: This is a handy feature for synchronization and synergy across teams. 

Con: Most of these features are locked behind a paywall and are only available to either Premium and Enterprise or only Enterprise licenses (either fully or through addition of functionality. For example, Release tracks are only available to Enterprise customers.) In addition, the costs will grow as you scale the offering to fit your growing needs. 

Pros and cons of Jira Data Center

I’ll be taking the same approach to talking about the pros and cons as I did when writing about Atlassian Cloud. Pros and cons are paired. 

Pro: Hosting your own system means you can scale horizontally and vertically through additional hardware. Extension of your systems is seamless, and there is no downtime (if you do everything correctly). Lastly, you don’t have to worry about the user limit – there is none. 

Con: While having more control over your systems is great, it implies a dedicated staff of engineers, additional expenses on software licensing, hardware, and physical space. Moreover, seamless extension and 0% downtime are entirely on you.

Pro: Atlassian has updated the DC offering with native bundled applications such as Advanced Roadmaps, team calendars and analytics for confluence, insight asset management, and insight discovery in Jira Service Management DC.

Con: Atlassian has updated their pricing to reflect these changes. And you are still getting fewer “bells and whistles” than Jira Cloud users (as we can see from the feature comparison). 

Pro: You are technically safer as the system is supported on your hardware by your specialists. Any and all Jira server issues, poor updates, and downtime are simply not your concern.
 

Con: Atlassian offers excellent security options: data encryption in transit and rest, to mobile app management, to audit offerings and API token controls. In their absence, your team company has to dedicate additional resources to security. 

Pro: Additional benefits from Atlassian, such as the Priority Support bundle (all DC subscriptions have this option), and the Data center loyalty discount (more on that in the pricing section.)

The Pricing

Talking about pricing of SaaS products is always a challenge as there are always multiple tiers and various pay-as-you go features. Barebones Jira Cloud, for instance, is completely free of charge, yet there are a series of serious limitations. 

Standard Jira Cloud will cost you an average of $7.50 per user per month while premium cranks that price up to $14.50. The Enterprise plan is billed annually and the cost is determined on a case-by-case basis. You can see the full comparison of Jira Cloud plans here. And you can use this online calculator to learn the cost of ownership in your particular case.

  • There are certain discounts for apps depending on your partnership level.
  • Depending on your situation, you may qualify for several Jira Data Center discount programs:

What should be your User Migration strategy?

Originally, there were several migration methods: Jira Cloud Migration Assistant, Jira Cloud Site Import, and there was an option to migrate via CSV export (though Jira actively discourages you from using this method). However, Jira’s team has focused their efforts on improving the Migration Assistant and have chosen to discontinue Cloud Site Import support.

Thanks to the broadened functionality of the assistant, it is now the only go-to method for migration with just one exception. If you are migrating over 1000 users and you absolutely need to migrate advanced roadmaps – you’ll need to rely on Site Import. At least for now, as Jira is actively working on implementing this feature in their assistant.

Here’s a quick comparison of the options and their limitations.

 FeaturesLimitations
Cloud Migration AssistantApp migration

Existing data on a Cloud Site is not overwritten

You choose the projects, users, and groups you want to migrate

Jira Service Management customer account migration

Better UI to guide you through the migration

Potential migration errors are displayed in advance

Migration can be done in phases reducing the downtime

Pre- and post-migration reports
You must be on a supported self-managed version of Jira
Site ExportCan migrate Advanced RoadmapsApp data is not migrated

Migration overrides existing data on the Cloud site

Separate user importUsers from external directories are not migrated

No choice of data you want or don’t want migrated

There’s a need to split attachments into up to 5GB chunks

Higher risks of downtime due to the “all or nothing” approach

You must be on a supported self-managed version of Jira

Pro tip: If you have a large base of users (above 2000), migrate them before you migrate projects and spaces. This way, you will not disrupt the workflow as users are still working on Server and the latter migration of data will take less time. 

How to migrate to Jira Cloud

Now that we have settled on one particular offering based on available pricing models as well as the pros and the cons that matter the most to your organization, let’s talk about the “how”. 

How does one migrate from Jira Server to Jira Cloud?

Pre-migration checklist

Jira’s Cloud Migration Assistant is a handy tool. It will automatically review your data for common errors. But it is incapable of doing all of the work for you. That’s why we – and Atlassian for that matter – recommend creating a pre-migration checklist.   

Smart Checklist will help you craft an actionable, context-rich checklist directly inside a Jira ticket. This way, none of the tasks will be missed, lost, or abandoned. 

Below is an example of how your migration checklist will look like in Jira. 

Feel free to copy the code and paste it into your Smart Checklist editor and you’ll have the checklist at the ready. 

# Create a user migration plan #must
> Please keep in mind that Jira Cloud Migration Assistant migrates all users and groups as well as users and groups related to selected projects
- Sync your user base
- Verify synchronization
- External users sync verification
- Active external directory verification
## Check your Jira Server version #must
- Verify via user interface or Support Zip Product Version Verification
> Jira Migration Assistant will not work unless Jira is running on a supported version
## Fix any duplicate email addresses #must
- Verify using SQL
> Duplicate email addresses are not supported by Jira Cloud and therefore can't be migrated with the Jira Cloud Migration Assistant. To avoid errors, you should find and fix any duplicate email addresses before migration. If user information is managed in an LDAP Server, you will need to update emails there and sync with Jira before the migration. If user information is managed locally, you can fix them through the Jira Server or Data Center user interface.
## Make sure you have the necessary permissions #must
- System Admin global permissions on the Server instance
- Exists in the target Cloud site
- Site Administrator Permission in the cloud
## Check for conflicts with group names #must
- Make sure that the groups in your Cloud Site don't have the same names as groups in Server
> Unless you are actively trying to merge them
- Delete or update add-on users so not to cause migration issues
- Verify via SQL
## Update firewall allowance rules #must
- None of the domains should be blocked by firewall or proxy
## Find a way to migrate apps #must
- Contact app vendors
## Check public access settings #must
- Projects
- Filters
- Filters
- Boards
- Dashboards
## Review server setup #mst
- at least 4gb Heap Allocation
- Open Files limit review
- Verify via support zip
## Check Server timezone #must for merging Cloud sites
- Switch to UTC is using any other timezone
> Add a system flag to the Jira Server instance -Duser.timezone=UTC as outlined in this article about updating documentation to include timezone details.
## Fix any duplicate shared configuration
## Storage limits
## Prepare the server instance
- Check data status
- All fields have value and are not null
-Any archived projects you wish to migrate are activated
## Prepare your cloud site
- Same Jira products enabled
- Same language
- User migration strategy
## Data backup
- Backup Jira Server site
- Backup Cloud site
## Run a test migration
- Done
## Notify Jira support
- Get in touch with Jira migration support

Use backups

On the one hand, having all of your Jira products on a server may seem like a backup in and of itself. On the other hand, there are data migration best practices we should follow even if it’s just a precaution. No one has ever felt sorry for their data being too safe. 

In addition, there are certain types of migration errors that can be resolved much faster with having a backup at hand. 

  1. Jira Server Database backup: this step creates a DB backup in an XML format.
    1. Log in with Jira System Admin permissions
    2. Go to system -> Import and Export -> Backup Manager -> Backup for server.
    3. Click the create Backup for server button. 
    4. Type in the name for your backup. 
    5. Jira will create a zipped XML file and notify you once the backup is ready. 

  1. Jira Cloud Backup: This backup also saves your data in an XML format. The process is quite similar to creating a Jira Server backup with the only difference taking place on the Backups page.
    1. Select the option to save your attachments, logos, and avatars.
    2. Click on the Create backup button. 

  1. As you can see, the Cloud backup includes the option to save attachments, avatars, and logos. This step should be done manually when backing up Server data.
    1. Create a Zip archive for this data
    2. Make sure it follows the structure suggested by Atlassian

Migrating your Jira instance to the cloud via the Jira Migration Assistant

Jira Cloud Migration Assistant is a free add-on Atlassian recommends using when migrating to the cloud. It accesses and evaluates your apps and helps migrate multiple projects. 

Overall, the migration assistant offers a more stable and reliable migration experience. It automatically checks for certain errors. It makes sure all users have unique and valid emails, and makes sure that none of the project names and keys conflict with one another. 

This is a step-by-step guide for importing your Jira Server data backup file into Jira Cloud.

  1. Log into Jira Cloud with admin permissions
  2. Go to System -> Import and Export -> External System Import
  3. Click on the Jira Server import option

  1. Select the backup Zip you have created 
  2. Jira will check the file for errors and present you with two options: enable or disable outgoing mail. Don’t worry, you will be able to change this section after the migration process is complete. 
  3. Then you will be presented with an option to merge Jira Server and Jira Cloud users
    1. Choosing overwrite will replace the users with users from the imported files
    2. The merge option will merge groups with the same name
    3. Lastly, you can select the third option if you are migrating users via Jira’s assistant
  4. Run the import

How do you migrate Jira Server into Jira DC?

Before we can proceed with the migration process, please make sure you meet the following prerequisites:

  1. Make sure you are installing Jira on one of the supported platforms. Atlassian has a list of supported platforms for Jira 9.1.
  2. Make sure the applications you are using are compatible with Jira DC. You will be required to switch to datacenter-compatible versions of your applications (they must be available). 
  3. Make sure you meet the necessary software and hardware requirements:
    1. You have a DC license
    2. You are using a supported database, OS, and Java version
    3. You are using OAuth authentication if your application links to other Atlassian products

Once you are certain you are ready to migrate your Jira Server to Jira Data Center, you can proceed with an installation that’s much simpler than one would expect.

  1. Upgrade your apps to be compatible with Jira DC
  2. Go to Administration -> Applications -> Versions and licenses
  3. Enter your Jira DC License Key
  4. Restart Jira

That’s it. You are all set. Well, unless your organization has specific needs such as continuous uptime, performance under heavy loads, and scalability, in which case you will need to set up a server cluster. You can find out more about setting up server clusters in this guide.

Pdf2gerb: Perl Script Converts PDF Files to Gerber format

pdf2gerb

Perl script converts PDF files to Gerber format

Pdf2Gerb generates Gerber 274X photoplotting and Excellon drill files from PDFs of a PCB. Up to three PDFs are used: the top copper layer, the bottom copper layer (for 2-sided PCBs), and an optional silk screen layer. The PDFs can be created directly from any PDF drawing software, or a PDF print driver can be used to capture the Print output if the drawing software does not directly support output to PDF.

The general workflow is as follows:

  1. Design the PCB using your favorite CAD or drawing software.
  2. Print the top and bottom copper and top silk screen layers to a PDF file.
  3. Run Pdf2Gerb on the PDFs to create Gerber and Excellon files.
  4. Use a Gerber viewer to double-check the output against the original PCB design.
  5. Make adjustments as needed.
  6. Submit the files to a PCB manufacturer.

Please note that Pdf2Gerb does NOT perform DRC (Design Rule Checks), as these will vary according to individual PCB manufacturer conventions and capabilities. Also note that Pdf2Gerb is not perfect, so the output files must always be checked before submitting them. As of version 1.6, Pdf2Gerb supports most PCB elements, such as round and square pads, round holes, traces, SMD pads, ground planes, no-fill areas, and panelization. However, because it interprets the graphical output of a Print function, there are limitations in what it can recognize (or there may be bugs).
