The Hardware and Software Used in Space

One of humanity’s highest achievements involves exploring the cosmos above us, pushing our technology to its limits to perform inspiring feats of science. Here’s a look at the hardware and software that made the grade for the mission — and the special considerations involved for building and maintaining mission-critical operating systems that will run in a high-radiation zero-gravity environment.

SpaceX’s Dragon 2 and Starlink

In May SpaceX’s reusable rocket, the Falcon 9, launched its small Dragon cargo-carrying space capsule, this time carrying two NASA astronauts to the International Space Station, where they stayed for two months before returning safely to earth. In June ZDNet quipped that the launching rocket was “powered by liquid oxygen, rocket-grade kerosene, and Linux.”

“Like supercomputers, Internet of Things devices, and many mission-critical devices, the Falcon 9 flies with Linux.”

But it’s not necessarily a standard distro. Instead, the rocket’s onboard operating system uses “a stripped-down Linux running on three ordinary dual-core x86 processors” which control the rocket’s engines as well as its flightpath-directing grid fins. Each processor runs a separate version of the flight software — written in C/C++ — and “If there’s any disagreement, the decision is thrown out and the process is restarted.”

In June the Dragon capsule’s software developers answered questions on Reddit, explaining that “We don’t use any third-party distribution, but maintain our own copy of the kernel and associated tools.” Though they call it “mostly unmodified,” they’ve obviously had to add custom drivers for SpaceX’s hardware. Jeff Dexter, who runs the Dragon’s Flight Software and Cybersecurity, added that for both the Falcon 9 rockets and the Dragon capsule, “We use C++ for all vehicle control systems, Python for tools, testing and automation, and Javascript/HTML/CSS for our displays.”

And Matt Monson — who moved from the Dragon project to SpaceX’s satellite internet service Starlink — posted that Starlink uses a lot of application-specific integrated circuits (ASICs), and that they too have a lot of experience with Linux. “For some level of scope on Starlink, each launch of 60 satellites contains more than 4,000 Linux computers. The constellation has more than 30,000 Linux nodes (and more than 6,000 microcontrollers) in space right now.

“And because we share a lot of our Linux platform infrastructure with Falcon and Dragon, they get the benefit of our more than 180 vehicle-years of on-orbit test time.”

Can you use WordPress for anything other than blogging? To your surprise, yes. WordPress is more than just a blogging tool, and it has helped thousands of websites and web applications to thrive. The use of WordPress powers around 40% of online projects, and today in our blog, we would visit some amazing uses of WordPress other than blogging.
What Is The Use Of WordPress?

WordPress is the most popular website platform in the world. It is the first choice of businesses that want to set a feature-rich and dynamic Content Management System. So, if you ask what WordPress is used for, the answer is – everything. It is a super-flexible, feature-rich and secure platform that offers everything to build unique websites and applications. Let’s start knowing them:

1. Multiple Websites Under A Single Installation
WordPress Multisite allows you to develop multiple sites from a single WordPress installation. You can download WordPress and start building websites you want to launch under a single server. Literally speaking, you can handle hundreds of sites from one single dashboard, which now needs applause.
It is a highly efficient platform that allows you to easily run several websites under the same login credentials. One of the best things about WordPress is the themes it has to offer. You can simply download them and plugin for various sites and save space on sites without losing their speed.

2. WordPress Social Network
WordPress can be used for high-end projects such as Social Media Network. If you don’t have the money and patience to hire a coder and invest months in building a feature-rich social media site, go for WordPress. It is one of the most amazing uses of WordPress. Its stunning CMS is unbeatable. And you can build sites as good as Facebook or Reddit etc. It can just make the process a lot easier.
To set up a social media network, you would have to download a WordPress Plugin called BuddyPress. It would allow you to connect a community page with ease and would provide all the necessary features of a community or social media. It has direct messaging, activity stream, user groups, extended profiles, and so much more. You just have to download and configure it.
If BuddyPress doesn’t meet all your needs, don’t give up on your dreams. You can try out WP Symposium or PeepSo. There are also several themes you can use to build a social network.

3. Create A Forum For Your Brand’s Community
Communities are very important for your business. They help you stay in constant connection with your users and consumers. And allow you to turn them into a loyal customer base. Meanwhile, there are many good technologies that can be used for building a community page – the good old WordPress is still the best.
It is the best community development technology. If you want to build your online community, you need to consider all the amazing features you get with WordPress. Plugins such as BB Press is an open-source, template-driven PHP/ MySQL forum software. It is very simple and doesn’t hamper the experience of the website.
Other tools such as wpFoRo and Asgaros Forum are equally good for creating a community blog. They are lightweight tools that are easy to manage and integrate with your WordPress site easily. However, there is only one tiny problem; you need to have some technical knowledge to build a WordPress Community blog page.

Software Developer vs Software Engineer — Differences: Bogus or Real?

Software Developers vs Software Engineers

Personally, it pisses me off. Every time I see an article on this topic, my emotional bank account gets robbed. They are all about SEO. Inappropriate keywords squeezed into tiny sentences just to get better rankings. No intent to entertain or enlighten the reader whatsoever. Sometimes, such articles can even be outright wrong.

And even though the purpose of this blog post can be to generate traffic, I tried to make it more of a meaningful rant than a lifeless academic essay.

So, let’s see how you feel by the time you are done reading this paper.

Without further ado:

Since there are no proper interpretations of both terms, a lot of people use them interchangeably.

However, some companies consider these terms as job titles.

The general “programmer-developer-engineer” trend goes along the lines of:

  • programmer is someone who knows how to code, understands algorithms and can follow instructions. Yet, it doesn’t go further in regards to responsibilities.
  • developer is someone superior to the programmer. Except for coding, they also do design, architecture, and technical documentation of the software component they are building. They might be referred to as leaders, but not necessarily.
  • Finally, an engineer implies that you are the real deal. You’ve graduated with a degree, have some tech knowledge, and preferably experience… and you are capable of designing a software system (a combination of software components your peons, the programmers, have built). You’re like an overseer. You can see the bigger picture. And it’s your responsibility to clearly explain that “picture” to your team.
