CIS is a free, feature-heavy security suite that has developed a cult following among tech enthusiasts. While it is not the prettiest or the most beginner-friendly software on the market, its unique approach to threat containment—specifically its platform and Auto-Containment technology—makes it one of the most technically robust defenses available. The Core Philosophy: Default Deny vs. Default Allow To understand CIS, you must understand the fundamental flaw of traditional antivirus (AV) software. Standard AV relies on signature-based detection (a blacklist). If a virus is new (a "zero-day" exploit) and not yet in the database, it often slips through.
In the crowded world of cybersecurity, most users face a binary choice: pay a premium for robust protection or settle for a basic, free-tier solution that often lacks advanced features. Comodo Internet Security (CIS) disrupts this model entirely.
If you are willing to spend 20 minutes learning the "Allow/Block/Contain" prompts, CIS is arguably the strongest free security suite on the planet. If you want a "set it and forget it" solution, stick to Windows Defender or Bitdefender. But for those who prioritize security over aesthetics, Comodo remains the reigning champion of the freeware fortress.
Finally, rocketry software that makes designing so much easier and faster! Instead of typing in values, just use your mouse to move, resize, and edit elements.
Can you use graphical design software? Then you can use SpaceCAD! Move elements, change fin size and fin points, resize tubes with your mouse - it's really the same thing.
You can see the effects right away: Optimizing your design is so much easier. It's super fun to experiment with different design options!
SpaceCAD calculates stability on the fly. The center of gravity (CG), center of pressure (CP), stability, and weight are always updated - so you can be sure your design will fly straight and true.

Simulate the flight of your model rocket with just one click. SpaceCAD's flight prediction displays a visual graph of your rocket's flight profile - from launch to landing.
No more waiting and no need for complex flight setup dialogs.
SpaceCAD simulates your rocket's flight: How high it flies (maximum altitude), how fast it becomes (maximum speed), and how hard it accelerates. Your rockets can have up to three three stages.

Reuse has been a cornerstone of model rocketry from the beginning - and SpaceCAD helps you recover your rockets safely!
Which parachute is the right one? Find out with SpaceCAD's recovery tools. Your rocket can have up to two recovery devices. These can be a parachute or a streamer, and you can pick them from the large database.
You can also determine when the parachute opens. This usually is determined by the ejection of your rocket engine. But SpaceCAD also lets you choose more complex scenarios that can be triggered using a flight computer.
Another important information is how far your rocket will drift in windy conditions.
Learn more about recoverySpaceCAD helps you build your design and make it real. This also means that SpaceCAD contains helpful printouts and export tools that help you build your rocket faster and easier.
The printout examples are with metric units. SpaceCAD also supports imperial units (inches, ounces).
Sometimes, you want to take your rocket data offline. Printouts are the best way:
-> Use the rocket datasheet (PDF) to take your rocket's information everywhere you go.
-> The rocket parts list (PDF) lists all your rocket's element and gives you detailed insight.
To help you turn your rocket design into a real, flying model rocket, SpaceCAD offers tools that help you do that:
-> The transition printout provides a cutout pattern for your rocket transitions.
-> The nose cone printout helps you follow the shape of your nose cone.
-> You can print centering rings (PDF) or export them (SVG) to print them directly with a laser cutter.
-> The multi-page parachute printout allows you to sew your own parachutes.
The fin-position/-alignment and cutout guides (PDF) help you to cut your fins and align them perfectly on your finished rocket.
You can also export the fin to cut it with a laser cutter: Fin Laser Cutter File (SVG)
