Why you shouldn't use 3rd Party DNS Managers

3rd Party CDN’s are websites that allow you to host your DNS Zone with them, rather than just pointing your nameservers directly to your host or using your domain registrars DNS.  A few examples of 3rd party DNS Providers would be Cloudflare, Shovl.io, and FreeDNS.  They all require you to point your domain names nameservers to their server hostnames so that they can host all of your DNS Queries.  This puts you at risk of more downtime, slower average load time, and potentially more security risks.  Downtime because if they experience an issue causing your website to go down, and your actual host server is still up, that wastes uptime and causes major disruptions to your visitors.  Slower average time because instead of pointing your nameservers directly to your host server or DNS Registrar, they have to go through a whole 3rd Party DNS Zone Manager and CDN, and then that CDN And DNS Zone has to process the DNS Query you’ve just sent and then send that DNS Query to your host server, causing a slower average load time.  And finally, potentially more security risks because if the 3rd Party company experiences one little minor issue, it could cause your website to go down, and if you are using one of their “DNS Shields (this hides your origin server IP Address)”, they can get your origin IP and send a denial of service attack to you, meaning it will overload your origin server because they passed through the 3rd Party DNS Shield, and they are now able to send tons of packets to your origin server.  Let’s say your origin server speed is around 100MBPS, they can send a 200GBPS Attack and successfully take down your origin server.  It’s better to have an actual functional server with a good denial of service mitigator.  We at Swivro have stopped using a 3rd party CDN, and our average load time increased by around 5 SECONDS.

Starship SN10 Aborts at T - 0 Seconds for its 10km test flight.

  Moments ago, Starship SN10 attempted a flight to 10km, to then orient itself into a unique horizontal bellyflop position, flip itself upright after it has descended to about 1km, deploy the landing legs, and touch down on the landing pad softly. This vehicle, Starship Number 10, uses Liquid CH4 (methane) and Liquid Oxygen aka LOX/LO2, used by its 3 powerful Raptor engines.  Today, SpaceX started their official stream for the Starship SN10 Flight. SpaceX have privated the stream replay, so we cannot replay it. In case you want the link:  https://www.youtube.com/watch?v=DDEgFsefrGw&t=541s The vehicle began fueling up with Methane and LOX, and then shortly after, it started the engine chill process, which is the process of chilling the engines down in preparation for engine ignition, so the engine material does not crack or get damaged from sudden shock. The vehicle attempted to start up its 3 Raptor engines, by opening the fuel & oxidizer valves, starting up the turbopumps, sho

What is “the best” programming language?

Programming languages, there are so many of them. Some programming languages are way easier to learn than other ones. But which programming language, is “the best” programming language? This question, it is not really answerable. There is no “best programming languages”, they are all meant for different things, well, MOST of them. If I were to compare 2 different programming languages, meant for very similar things, like Batch and Bash, I would say Batch is easier, as its Syntax is not as confusing as Bash’s to the average person. Here is another example, C# is primarily used for computer applications, mostly on Windows, and HTML is a markup language, being used to make websites. I cannot compare C# (it is pronounced “See Sharp” if you didn’t know) because they are used for completely different things. It wouldn’t make sense to say, “C# is way better”, because what is it better at? Developing desktop applications? Sure! Then I can say HTML is better at making websites, it is not a logi

How do you know the universe was not created a few minutes ago?

       The universe is the giant area of space that we live in, which is observable. Anything past our universal border is not in our universe. People do say the universe is constantly expanding, but there is no proof of that, as the "imaginary" or, maybe not imaginary border at the "end" of our universe. But, how do you know that the universe even exists? Were you even in it last week? Did last week even exist? Last week, the universe could have been created, and you do not have proof against it. All of your knowledge and memory could have easily popped into existence a few seconds ago, tricking you into thinking you have existed for longer than you think. This is likely, but also unlikely, it is a 50/50 chance. A reason that this is unlikely is, there are a lot of things that do not make sense in our universe. Like, why does matter attract matter, resulting in gravity? This exists in our universe, but can it exist in a different universe? Not really, or most likel
