An evolution of v1 here: https://www.redhat.com/archives/libguestfs/2020-April/msg00035.html I want to generalize the tmpdisk plugin, particularly so you can use commands like ‘qemu-img create’ or even ‘virt-builder’. (Actually virt-builder really works - I tested it - but of course it causes a 30+ second delay when connecting to the server.) You can now use commands such as: nbdkit tmpdisk

...twise. In this context, we take a file, and go through each character and encrypt it. But why are the ^ and % operators used here: def encrypt(reader, writer) key_index = 0 while not reader.eof? clear_char = reader.getc encrypted_char = clear_char ^ @key[key_index] writer.putc(encrypted_char) key_index = (key_index + 1) % @key.size end end thanks for response -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I am using rubyzip and am trying to put a huge csv file with 1.4 million rows into the zip file. Using jruby I get a out of heap error. I believe the error happens in the block below: Zip::ZipOutputStream.open(zip_path) do |zos| zos.put_next_entry(File.basename(csv_path)) zos.print IO.read(csv_path) end -- You received this message because you are subscribed to the Google

If you plan on calling C runtime library functions, you probably want to do what I did: Cheat, and make a libruntime.a (with C functions to do stuff your compiler can't do natively) and then link that using clang or gcc. https://github.com/Leporacanthicus/lacsap/blob/master/binary.cpp#L124 At some point, I plan to replace my runtime library with native Pascal code, at which point I will be

v2 was here: https://www.redhat.com/archives/libguestfs/2020-April/msg00075.html In v3: - Add [VAR=VALUE ...] to manual. - Various minor improvements to the manual. - Work (at least, in theory - not tested) with block devices or symlinks. I didn't document this because it's hard to ensure these files or block devices would be cleaned up, so here be dragons. - Remove O_NOCTTY. -
