magic numbers are vital for filesystem reference in kernel code to distinguish load order of partitions in a disk, and probably used for memory allocation, and permissions. The reason why the magic code exists among code itself seems a litt

I cannot fathom how complicated arbitrary code execution could get with multi byte characters that could use shift registers, null bytes and byte order marks with determinism in a NOP slide on a heap spray. Filtering only printable user inp

no, the fsync call remains the same as it does in ext3 and most filesystems. However in ext4 there is no need to call sync unless you disable batch processing of synchronous writes.

manpage suggests the article is not mistaken. `max_batch_time=0` disables batch processing synchronous write operations. the default is 15ms. It seems like a good idea for client filesystem to mount synchronously for data integrity. I'

xdr was developed by sun, i don't think that is the issue here. I think it is the service that rpc doesn't recognize. i'm assuming in this case it is rails under ruby or something using ssh or ssl that require secure and non-

good point. i think ' get ting env vars' is the bigger issue here.

It seems like most people here don't see what the root cause here is. System and user level processes with high order 'actions' for idempotent handling of secure channel operations (session negotiation, out-of-band data) are

You can try setting up a vpn and no tcp/udp is necessary. Pinhole could be accessed over local network.

So I’ve never setup a vpn before, I’ve been trying to decide how to make this simple for windows clients and phones. Must I have a vpn client? I’m using IPSec, ssl, and LDAP on the public end. I don’t want a client app. A gateway/route

I wonder if there are any real programmers out there who have decoded GIF by hand. The IETF is clear that the header should be 6 7bit bytes (GIF##a), and the ends with `\x00\x3b`. without LZW, it should be trivial to append a frame to an im

files are an abstraction and reference to objects in memory. The only problem I see is storage life cycle without cache in volatile plus redundant non-volatile memory. Same problem for blocks and segments, no?

pH balance of water and oxidization/electronegativity of the air could impact the quality of concrete.
