This may be a silly question but should I use the 32 bit or 64 bit version of Eclipse on my Mac?
I'm fully up to date with Snow Leopard and all patches and I have a pretty recent iMac (30", Dual Core, 3GB)
I thought that Java on Snow Leopard was now 64 bit only so can't understand why there is a 32bit download. Is it just the Eclipse download page that is showing 32 bit for older versions of OSX?
You're probably better off with the 64-bit edition. Nearly all the system software is 64-bit in Snow Leopard, and if you only run 64-bit apps, you don't pay the cost of having to load the 32-bit runtimes (which can consume quite a lot of memory). It may also benefit from the 64-bit memory model, though I'm not sure how well the JVM takes advantage of that yet. I expect the 32-bit version is provided for Leopard (and earlier) compatability.
I would use 64bit Eclipse.
safe bit is 32-bit :)

How to repair qsc.dll?
Unfortunately, the quantum development kit only works with 64 bits OS (Windows, MacOS, Linux), and it appears that you are using a 32bit version of Windows.
I don't have any good option for you, except to upgrade the OS but I'm not certain there is a 64 bit version of Windows 10 Education.
As a limited option, you can try to execute some simple code in tio: https://tio.run/#qs-core.
I encourage you to create an item about this in https://quantum.uservoice.com/ where most of the feedback for the quantum development kit is gathered.
What are the system requirements for vscode?
The download page only shows the different platforms this is available on, but doesn't mention any requirements such as Windows version (i know it doesn't work on XP) or additional required components, such as the .NET framework.
System requirements for VSCode are available on the documentation page.
In a nutshell, VSCode now is self contained for Linux, Mac and Windows. There is a complete list for the additional helpful tools available on the setup page.
It's not listed in their requirements, but you'll also need a decent video card. It may seem ridiculous, since it's mainly displaying text, but vscode's GPU hardware requirement is well beyond what other applications require. There is a switch --disable-gpu to switch it to software rendering but it's still laggy.
As of Version 1.32
1.6 GHz or faster processor with 1 GB RAM recommended
OS X Yosemite
Windows 7 (with .NET Framework 4.5.2), 8.0, 8.1 and 10 (32-bit and 64-bit)
Linux with GLIBCXX version 3.4.15 or later, GLIBC version 2.15 or later, tested with Linux (Debian): Ubuntu Desktop 14.04, Debian 7, Linux (Red Hat): Red Hat Enterprise Linux 7, CentOS 7, Fedora 23
I need to test my C code for 32- and 64-bit versions of Windows (XP and 7) and Linux. But I have got access only to their 64-bit installations.
Question: Is it possible to use some boot-time settings or other hacks to run/emulate these OSes in 32-bit mode? If not, is there any other way to test the portability of my C code?
Note: The C code in question is not a full-fledged application but rather a .dll/.so file.
Neither Linux nor Windows 64Bit can run as 32Bit OS. Also, while you can run 32Bit executables on the 64Bit OS, it is not quite the same as running the same under a 32Bit OS. But it might work as a quick screening test. Besides, you certainly want that to work as well, right?
Your choices are full multi-boot setup, using VMs (might hide/expose bugs), being content with the emulation layer or running the other OS's on different hardware.
BTW: If you have Windows 64Bit, the license allows you to run 32Bit instead and vice versa. Anyway, you might want to check different language versions as well...
This might be a dumb/naive question, and if it is please excuse me :)
I have a brand new machine with the following specs:
Inter Core i7 2600#3.4GHz
RAM 8 GB
Windows 7
This machine has a 64 bits architecture.
On my previous machine, I used to install 32 bits versions of Eclipse and run it using a 32 bits JRE, and my current Eclipse setup works perfectly on the new machine.
I tried to install a 64bits version of Eclipse, and run it with a 64 bits JRE, and I am wondering if there are any compelling reasons to switch to this kind of setup or stick to my existing install. I guess that I would have to reinstall all the plugins, and maybe find that some of them are not compatible with the 64 bits version of Eclipse.
So far, the 64 bits version seems to need quite some more RAM than the 32 bits version, which is something that I expected, but nothing seems to have improved.
Thanks for your advice!
In general I use 64-bit Eclipse without problem, but there can be issues around plug-ins such as:
Adobe Flash Builder only works with 32-bit
The Subversion plug-in Subclipse needs a native 64-bit version of Subversion installed separately
There may be more but those are the ones I've encountered in the past.
Moving to 64-bit gives you access to more addressable memory but it won't speed anything up, in fact it might reduce performance in some cases (but nothing I see as significant to what I do).
Well the only thing that will improve is that you are able to use the advantages of 64bit. Other then that I'm not aware of any improvement.
For example what's better in 64bit is that if you have a very large project set you would be able to handle it more comfortably. For more information on 64-bit please look here
If you want to be on the edge of technology your choice would of course be the 64bit setup.
About the ram, this is expected because some of the Datatyps now use 64bit and are therefore larger to store in memory.
For most plugins you will get a 64bit version or alternative and so far for what I've used it it always worked.
I have just watched the bug report http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6972329 so I want to ask... Is there a JDK upgraded version which handles the problem? Because if I develop an app with 32-bit JDK 6 will it work on 64-bit linux?
I have compiled my project with jdk 1.6.0_05 so I am not sure will it work for 32 or 64 bit linux ... won't it be the user.home as '?'
Thanks
The bug has absolutely nothing to do with the JDK used to compile Java code - Java bytecode is completely platform independant. The bug only occurs when you run a Java app on a 32bit JVM on a 64bit Linux, and even then it seems to depend on a specific (and possibly faulty) LDAP configuration.
