No, because the pages aren't mapped to anything -- not disk, RAM, or an external paging device. Allocating a chunk of memory typically doesn't map those pages to anything immediately (since there's no benefit to doing that e

But since the memory is never actually backed by anything, it doesn't have a real effect except in the accounting of the process. No additional memory is used by locking it.

Linux cgroups and Solaris containers atleast also provide a way to avoid paging to disk, without modifying the program.

It is significant to note that: 1. You don't have to lock all your memory (although it may be hard to capture all the intermediate buffers if you don't). 2. You still need to clear the memory buffers after they're no longer g

I assume this is referring to some mechanism like `mlockall(2)` or using cgroups to disable using paging. Is the "excess" memory dirtied ? It's not clear why having the pages mapped but unaccessed entirely would cause a per

You could look to TclQuadCode for inspiration as it can make Tcl code 66x faster in the best cases.

Such views can also be provided by userspace filesystems (fuse, coda, nfs, 9p, etc). I have a fuse filesystem that shows different users different views of the filesystem, as a basic example.

I don't know the answer to your StackOverflow question as I don't use macOS/Mac OS X. What I ended up doing to help this process along is including the relevant certificates inside my DOD Smartcard PKCS#11 module as certifica

What happens in some cases is that new intermediate CAs are introduced and older client's certificate stores are not updated. In this case it is a TLS server error as the TLS server should be sending you all the intermediate certs to

They are trusted by internal machines -- since a lot of internal authentication relies on these certificates. The DOD long ago moved away from password-based authentication mechanisms to certificate-based authentication (GSC-IS initially (

I'm not sure what specific training you're talking about regarding DIACAP (which it would likely have been when you were working there; now replaced with RMF), but over all the goal of certification and accreditation is about assu

A lot of the authentication is TLS client certificate authentication, SAML hosted by internal SAML IdP systems (such as ADFS) for web stuff. For most other things Kerberos (via PKINIT) is used. SSH authentication X.509 using PKIXSSH is rare

It is still experimental, but the output code is stable -- most of the work is in expanding its support for the Tcl language.

Also, modern Tcl can be compiled to machine code to a large degree thanks to TclQuadCode and LLVM.

Here you go: vTcl -- just like Visual Basic 3.0. Also, you get to use Tcl instead of Visual Basic, so even better ! http://vtcl.sourceforge.net/

by rkeene2 8y ago
In general, you want money to be scarce so that it does not devalue wildly. Money in Venezuela recently started lacking scarcity, to the detriment of those who tried to use it as money. An interesting debate that I found recently on which

In my view asserts are just a way of defining the contract of an interface that cannot be specified to the compiler/runtime any other way. They are a workaround of limitations of those systems, or rather the extend a system with infin
