I cross-compile an entire Linux distribution (even if you're compiling on Linux/x86_64 FOR Linux/x86_64, it's still going to get cross-compiled since it's a different platform). This is around 300 external/ups

The antecedent of "they" in the previous sentence is the company, not an individual. The individual creating the email, as a person, probably was not lying BUT since they were acting as an agent of the company, in an official cap

In this same vein is Filed, it does the minimal amount of work possible before handing off to the kernel to sendfile() the static resource. http://filed.rkeene.org/

This compatibility layer approach is quite common. Solaris Linux Branded Zones and FreeBSD Linux Emulation Layer (now defunct?) also did the same thing.

LPARs are closer to VMs than containers. WPARs (workload partitions) may be what you are thinking of.

Which is why AppFS doesn't rely on that and instead relies on the ability to present a single unified filesystem.

by rkeene2 8y ago
AppFS has no problem with that. The problem comes from keeping different packages on different disks -- since it caches them all into the same directory by default. It would be trivial to make it cache files from certain packages into dif

Much of that is documented in the page called "Getting Started": http://appfs.rkeene.org/web/home/Getting%20Started I'll summarize it here: 1. To use it to run application: a. Get AppFSd running

by rkeene2 8y ago
Yes. Since there's no explicit install step you can run as many versions as you want. You can of course copy the files to the cache of any system.

AppFS is a package manager for Linux that exists and solves all these problems, except the "putting them on different disks", which it doesn't prevent you from doing but it doesn't really make any sense either. http:&#x

It's literally what you described in the third paragraph: > All you need to distribute a software package is files, and a subsystem that maps files into the user's environment, and links together the files needed to run the sof

It's real annoying when Chrome crashes (which it does once or twice a week on average) because it restarts all your Android apps as well !

This is the whole point of a Linux distribution -- it takes the disparate parts and makes them into one coherent whole.

glibc could follow the same model, but it would be wasteful for them to do so, without symbol versioning. With symbol versioning they DO. The memcpy(3) example is why. An old implementation of memcpy(3) supplied in older versions of glib

It requires disabling a fair amount of the benefits of a Chromebook to enable. Yes, I have tried it. Also, the method it uses to display X11 applications is fairly terrible.

Thunderbird is by far the best MUA I've used. I use a Chromebook as my daily workstation and I cannot wait for it to support Linux applications so I can run Thunderbird rather than my current situation (a mix of web-mail and ALPINE).

And it can now be compiled to machine code (TclQuadCode), an amazing feat which should have further information presented at this year's Tcl conference (already underway).

AppFS ( http://appfs.rkeene.org/ ) is an extension of the idea proposed originally by 0install (in their original LazyFS approach).

Only if the fix involves breaking the old semantics entirely. It's possible in some cases to support old semantics in a safe way at the cost of performance, or in the case that it's not you can disable that call in such a way tha

Tcl beats it in terms of both transparency and ready-made-ness. In Tcl, all filesystem access goes through the Tcl Virtual Filesystem (VFS) layer. This is a layer of indirection that allows for the interpreter, including at the script-lev

It generally takes other languages a long time to become more like Tcl ;-)

by rkeene2 8y ago
This is in fact what Tcl Starkits/Starpacks do -- all access to the filesystem goes through the Tcl VFS, which can be redirected to the script level.

by rkeene2 8y ago
Tcl is still the king of this kind of distribution with Starkits/Starpacks. Since you can virtualize the filesystem within Tcl, you can pack in all your resources as regular files and generally scripts will work without knowing that t

After some experimenting it will fault all the mapped pages, causing the VM subsystem to try to back them. In Linux 4.4+ there is an a flag to `mlockall(2)` called "MCL_ONFAULT" which does not do that and instead locks the pages
