No, we use them for much low level stuff: to directly access memory regions, which is needed in some cases, and to use callbacks, in the case of handling page faults to reenter the interpreter.��<div><br></div><div>You can use any plugin as long as: a) you compile it as internal and b) the plugin doesn&#39;t make any syscall or use code from other libraries that make syscalls. I don&#39;t know if this is the case of openssl and curl.<br>

<span style="font-family:arial,sans-serif;font-size:13px;border-collapse:collapse">For all those who may be intrested, we are glad to announce that we have just uploaded an updated version of SqueakNOS to our site.��You can find the updated download links <a href="http://squeaknos.blogspot.com/p/download.html" target="_blank">here</a>.<div>





<br></div><div>This release adds the following items to the previous version:��(99.9% modeled with objects)</div><div><br></div><div>- Improved support for ATA devices access</div><div>- Implementation of a model of files and directories</div>





<div>- Implementation of FAT32 filesystem��</div><div>- Support for reading sources from the hard disk</div><div>- Support for X86 paging setup and handling of page faults</div><div>- Implementation of a model of free and used memory</div>





<div>- Implementation of image snapshotting (based on the paging mechanism)</div><div>- Based on Pharo, but also supporting Squeak and Cuis</div><div>- Added some primitives for communicating between VM and image</div><div>





- Support for Alien and FFI</div><div>- Added basic support for writing to serial via VM so that it&#39;s possiblo to out debug info to the outside world.</div><div>- Added pretty basic ATA benchmarks</div><div>- Added some scripts to automatize work done from the outside world</div>





<div>- Many code cleanups</div><div><br></div><div>Future directions are:��</div><div><br></div><div>- Support for Cog VM</div><div>- Investigate replacing SqueakNOS plugin with NativeBoost so that we do more on the image</div>





<div>- Offloading memory pages to disk</div><div>- More tests</div><div>- Benchmarks</div><div><br></div><div>For the brave ones, remember that you can always generate a SqueakNOS image by using the ConfigurationOfSqueakNOS (which is a bit outdated now), or by manually loading the packages from monticello. Also to generate a SqueakNOS VM download its code from GIT (hosted on��<a href="http://sourceforge.net/" style="color:rgb(0, 84, 136)" target="_blank">sourceforge.net</a>).</div>
