  • Stellarium 64-bit version

    Start64!Stellarium is a free open source planetarium for your computer. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope. It is being used in planetarium projectors. Just set your coordinates and go.

  • 32-Bit vs. 64-Bit OSes: What's the Difference?

    Start64!There are a lot of ways to count, but when it comes to computers there is only binary: 0 and 1. Each one is a considered a "bit." That means for 1-bit computing, you get two possible values; 2-bit means four values; then at 3 bits you double that to eight (2 to the third power, aka 2 cubed).

  • Why it matters whether your Windows is 32-bit or 64-bit

    Start64!I have to admit this isn’t something I’ve thought about in a long time, but I peeked around and lo and behold Microsoft’s latest OS—Windows 10—is being offered in a 32-bit version. Microsoft says it has at least 71 million 32-bit users still (as of 2014), and didn’t want to leave them out in the cold, or thrust them into the open arms of Cupertino (headquarters of rival Apple). Given this situation, I figured I’d explain the main difference between the two.

  • Do You Need More RAM To Run 32-Bit Programs On 64-Bit Windows?

    Start64!Most computers today ship with a 64-bit version of Windows, and often a minimal amount of RAM. This brings into question how well these systems perform. This is especially true when users want to run their legacy 32-bit software on these new computers. This is especially true when users want to run their legacy 32-bit software on these new computers.

  • nuBASIC 64-bit version

    Start64!nuBASIC is an implementation of an interpreter of the BASIC programming language distributed under GPLv2 License. It has been designed mainly for educational purposes both for C++ developers that can deal with a non-trivial example of C++11 programming and for nuBASIC's users, that may get hooked on programming.

  • How to Switch From 32-bit Windows 10 to 64-bit Windows 10

    Start64!Microsoft gives you the 32-bit version of Windows 10 if you upgrade from the 32-bit version of Windows 7 or 8.1. But you can switch to the 64-bit version, assuming your hardware supports it. If you had a 32-bit versions of Windows 7 or 8.1 installed on your PC and upgraded to Windows 10, Microsoft gave you the 32-bit version of Windows 10.

  • Impro-Visor 64-bit version

    Start64!Impro-Visor is a music notation program designed to help jazz musicians compose and hear solos similar to ones that might be improvised. The objective is to improve understanding of solo construction and tune chord changes. There are other, secondary, things it can do, such as improvise on its own.

  • C++ Tail Recursion Using 64-bit variables - Part 2

    Start64!In my previous post I talked about recursion problems in a Fibonacci function using 64-bit variables as function parameters, compiled using the Microsoft Visual C++ compiler. It turned out that while tail recursion was enabled by the compiler using 32-bit types it didn't really when switching to 64-bit ones.

  • C++ Tail Recursion Using 64-bit variables

    Start64!I want to share with you a problem I run into comparing iterative and recursive functions in C++. There are several differences between recursion and iteration, this article explains the topic nicely if you want to know more. In general languages like Java, C, and Python, recursion is fairly expensive compared to iteration because it requires the allocation of a new stack frame.

  • Alice 64-bit version

    Start64!Alice is an innovative 3D programming environment that makes it easy to create an animation for telling a story, playing an interactive game, or a video to share on the web. Alice is a freely available teaching tool designed to be a student's first exposure to object-oriented programming.

  • Microsoft Explains Why Windows 10 32-Bit Is Still Needed

    Start64!A few days ago, Gabriel Aul, head of the Windows Insider Program, confirmed in a short tweet that Windows 10 would also launch with a 32-bit SKU, thus putting an end to some weird rumors pointing out that Microsoft wants to step away from this architecture type with the new OS version.

  • How to Mark Your 64-bit App on Google Play Store using Version Codes for 64-bit ABIs for Android

    Start64!With Google's introduction of 64-bit ABIs for Android, we need to make some minor updates to Version Codes we use to publish and filter app on Google Play. The current suggestion make the 64-bit ABI 1 higher than the 32-bit code, making the 64-bit the preferred.

  • How to Develop and Evaluate 64-bit Android Apps on Intel x86 Platforms

    Start64!Nowadays more and more mobile devices are powered by 64-bit architecture, and using 64-bit Android* is a great way to gain access to that market. This article will introduce Android on Intel® 64-bit architecture and discuss its unique compatibilities, including technical details and performance gains for Android on Intel® Atom™ processor-based platforms.

  • Adopting the 64-bit ARM Architecture

    Start64!The ARM RISC architecture was introduced with the advent of ARMV4 and ARM7. This architecture could handle minimal instructions, and almost had no ability to perform mathematical calculations. With the inception of ARMv7 architecture, the processor design is drastically changed and immensely popular. One of the major segments in which the ARM operates, is in mobility devices. ARMv7 has facilitated its foray beyond the traditional ARM market. ARMv7 has three different profiles: Application, Real-time and Microcontrollers.

  • Why are 32-bit programs still running on my 64-bit version of Windows?

    Start64!Most PC’s shipping these days are rocking 64-bit versions of Windows 8.0 or 8.1. If you’re not sure how to check which bit architecture you have (32-bit or 64-bit) in Windows, there’s a quick command line trick for that. Today I want to show you something peculiar that you may not have noticed but once I bring it up you’ll certainly have questions.

  • What is the advantage of having a 64 bit Smartphone?

    Start64!Recently you might have heard of 64-bit smartphones and the fact that Android L now supports 64-bit architecture. For those not familiar with the term and don’t know what 64-bit is, we are going to take a look at why you should care and why there is such a huge difference between a 64 bit and non 64 bit smartphone.

  • x64 Assembly and C++ Tutorial 63 B: Box Blur C++ Coding

    Start64!In this video we'll code the box blur algorithm described in the previous part. This is a C++ implementation but it's going to be designed (I hope anyway...) to encourage an simple port to SSE.

  • x64 Assembly and C++ Tutorial 63 A: Double Pass Box Blur Description

    Start64!This small section of the tute contains a description and illustration of a very fast box blur algorithm. We want to select the fastest known algorithm for our own implementation, and the sliding window version I was thinking of implementing is nowhere near as fast as this one.

  • 64-Bit Mobile Computing – It Takes an Ecosystem

    Start64!The world of enterprise IT must pay attention any time a true development is made in mobile technology. Internally, the business might consider upgrading devices, while externally, mobile consumers will be affected and the organization’s mobile strategy might need adjustment. 64-bit computing is one of those mobile development worthy of enterprise IT’s attention.

  • x64 Assembly and C++ Tutorial 62: Box Blur Window

    Start64!It's been a long time. In this tute we'll start programming a more complex plugin for Imogen. It will be an implementation of the Box Blur function. It will include a Windows form with controls which will give the user some options as the plugin executes.
