Description: make-apache-postresql-isofs is a service that creates customized Linux distribution ISO images on the server-side after being provided input from a user from the web interface. These images are created on the fly from the distribution's original directory hierarchy that is stored in a ram disk. For more information, man(5)mkapagresqlisofs. The name comes from the fact that we combined the sources of mkisofs, Apache2, and Postresql into one monolithic application.
Known bugs: The path/usr/lib/mkapagresqlisofs installed by default creates a bit ordering that causes a buffer-overflow with bash's and tcsh's command completion causing the shells to crash. Users of these shells should make sure they manually type in mkapagresqlisofs to make configuration changes.
Like i said too, it makes more sense for me to download the small net-install iso and download each package from FTP. I was, in a round-about way, giving some dev advice, but at the same time, hoping the uselessness of such an idea would be immediately obvious since there are much better solutions already available. The guy did say create the ISOs on the fly on the server-side, so I was trying to entertain his idea.
You'd need a reasonable server with enough RAM to hold the entire distribution's packages in a RAM disk and probably an extra couple of Gigs. Even 10GigE would not be able to hose a good Quad opteron box with hypertransport so you'd probably be able to get away with having a reasonable number of concurrent connections.
I'd recommend snagging the source of mkisofs and changing the code for the output stream to point to something apache can forward or, whip up a small web server that does nothing but handle GETs for these on-the-fly isos based on session data stored in postgres or something.
I'd probably never use this though as I am a fedora person and I always use the 5 Meg boot.iso image and do an FTP install. As well, SuSE also offers the FTP install.
Informative? I wasn't aware of fingerprints changing over time. However, if the parent was trying to imply that unlike passwords which can be changed, fingerprints cannot, then I would wager that his comment lies closer to 'Insightful'. Of course, the parent could have also been attemping to be humorous, which in that case, I apologize for killing the joke >:-/
I was just being a jerk, trying to tear apart your generalization;) Yeah, for all intents and practical purposes, PVM is very dead. Most all parallel apps these days are using MPI.
I've done quite a bit of MPI programming using the MPICH and MPICH2 implementations. MPI itself is nothing more than a specification that addresses issues with sharing memory between processors, whether they are in the same 'box' or connected through some fabric like Ethernet or some of the high-speed interconnects.
The specification is focused mainly on the syntax of the API to make Fortran, C, C++, and Java (?Not sure if Java is actually part of the spec yet) codes compile and operate smoothly across different MPI implementations like MPICH or LAM, to name a couple (I've never run into an MPI implementation, personally, that has screwed with the standard. All my codes have always compiled and functioned cleanly across multiple implementations (after extensive debugging, of course;-) ).
MPICH and MPICH2 provide many different "drivers" to allow its use over 100Mb/GigE ethernet (ch_p4), Myrinet (provided by Myricom, ch_gm), Infiniband, ccNUMA or NUMA-like systems (ch_shmem, or lock-free ch_shmemlf), and drivers for globus systems.
With interconnect fabrics like ethernet and low-latency Myrinet and IB, Message passing typically involves passing actual data between hosts across this fabric and the ch_p4, ch_gm drivers handle this transparently (this part of the setup, selecting the driver, is a function of your Administrator and not the developer). On large memory SMPs, MPI may pass addresses or references rather than the actual data, taking advantage of the fact that the hardware is designed to allow any single CPU to address any region of memory rather than flooding the memory bus with unnecessary transactions.
Take parallel video rendering for example, where we might be simply gzipping each frame... on a cluster-style interconnect, each host must have a copy of the frame it is operating on so it must be passed along the interconnect to the host before work is done (or it can be read by each host from the original file, if that file is shared across the cluster or copied to each node. This becomes very I/O bound and suffers from the slowness of hard disks). On an SMP, a pointer to the beginning of that array may be passed to the thread or process trying to do the work, while the segment of that video is stored in RAM.
Being able to share memory in such a way allows fine-grained calculations like very-large-matrix operations over slower interconnects AND SMPs (though your performance on the slower interconnects will suffer because of the bandwidth or latencies induced by the interconnect).
As well, MPICH at least, provides excellent support for debugging parallel applications through the mpirun_dbg.* commands. It uses your favorite debuggers whether they be gdb, ddd, dbx, or totalview.
MPI in a nut shell, provides for the easy creation of multiple process threads and facilitates the sharing of data between each thread to enable parallel processing regardless of how your CPUs and memory are connected. Don't know anything about TIBCO though, nor have I ever heard of it... Sorry if this was too much or too little info. I'm not really aware of the average/.er's experience with such things.
Boohoo... I got modded to oblivion. Tough shit. You act like an ass, you'll get treated like an ass. You came across as crass, arrogant, and so as-a-matter-of-fact-ish that we could have sworn that you were the troll.
An "obvious troll post"? I beg to differ. An MDI interface for gimp would be great. Since they've added the top menu to the document window in Gimp 2, this has alieviated some of the headaches with using it, at least for me. How is asking for a perfectly legitimate feature an "obvious troll post"?
So, why don't you say something constructive and quit yer whining?
When we get our 24x17" LCDs next spring, we'll get rid of the black bezels AND have a resolution of 7680x4096. Then, this "HD" nonsense will look like over-scaled garbage!
I'd hate to be an assistant to a prosecutor trying someone for over a thousand crimes... Could you imagine the amount of paperwork? The bloody indictment "sheet" would dwarf War and Peace.
LINPACK is silly... but I would say that it's not quite as silly as this PI benchmark (although HPL is way too customizable for anyone's good). Given a hand-tweaked HPL.dat file, you can make even the most paultry cluster appear to perform quite well. Of course, that's the point in that you would like to create a problem similar to your main day-to-day tasks on your cluster (HPL.dat allows this) and see how fast it will run.
Top500 is kind of dubious as well given that each cluster runs its own customized HPL inputs. The list places in order a number of clusters that are really good at doing one particular thing and compares them as if they are doing the same thing. It seems rather bizzare, though that particular model for rating performance appears to have worked out rather well over the years.
Thank god I run beowulf clusters for a living... No chance of an MS switch there (as I also write the policy).
But in any case, the Scots needed the Right Tool for the Job(tm) and they went with MS Office (which IMHO, is a very comprehensive and useable piece of software). In the end, its a practical decision just as using Linux and OSS on our clusters is strictly a practical decision (most scientific codes were originally written for big Unix iron and were easily ported over to Linux). More power to them if they managed to get a better deal.
Nevermind the fact that he never stated that 507+13 = 547 nor was it implied. Any fool that has ever seen a book knows there are Copyright pages, a tables of contents and probably an index. Anyone with a clue would have noticed that.
If the person that did invent the next "iPod" used WinCE as the OS, his scenario would have been correct. Hence, your intended counter is rendered moot and unfounded.
The same "morality" that keeps stem cells from being used is the same "morality" that said jerking off was a sin (some "spilling your seed" nonsense) and that women should be burned at the steak for being witches. It's the same idiocy that we will look back upon in a hundred years or so while hanging our heads in shame.
What is so precious about human life? The "presciousness" of a human life is only an attribute that we as humans ascribe to ourselves, and is therefore hardly an objective assesment. We feel no remorse for testing chemicals, poisons, and experimental drugs on other living beings only because they do not have our organizational patterns or that wee-bit of extra intellect that allows us to band together to solve problems. Notice our seemingly unfounded compassion for more advanced species like marine mammals and other primates. We fight very hard for those species that we see as "closely resembling" ourselves while we, with the most carefree disregard, take apart, disect and brutalize lesser species.
Myself, I do not see us as "higher beings". Sure, our resoning sets us apart from other species, but it is not enough to justify the discrimination that we impart upon the collective population of this world. With this reasoning, logic suggests that if it is acceptable to what we do to other species, it is just as acceptable to do it to ourselves (and we do so everyday through open warfare, class warfare, and the brutal subjugation of "lesser" peoples). The Stem cell issue is such a minor blip on the "morally unconscionable" radar that I find it amusing that we fight over this, a practice with the sole purpose of helping to save and improve life, while we should be fighting over the other practices mentioned above whose only purpose is to harrass or extinguish it for the purposes of profit, nationalism, and personal glory. For such an intelligent species (supposedly) we have a rather bizzare collective reasoning, don't you agree?
More or less? There is a lot more involved than just that and I'm not even a rocket scientist.
Cabin pressure?
Properties of your fuel (how much do I need for the necessary amount of energy, is there anything better)?
VERY Low-power computing/control systems/life support?
Power generation, for that matter?
Returning to atmosphere and landing in one piece?
Flight control at speeds beyond Mach 10 (in atmosphere)?
Attitude control and maneuvering in space?
Logistics: at what velocity do we orbit, at what angle do we approach, and how much fuel do we burn for escape, in order for the moon's gravity to pull us back on a trajectory towards earth, not to mention optimal time windows for launch for the moon to be in the right place at the right time?
How do we shield from radiation and keep the craft light-weight for initial take off?
How do we regulate cabin temperature?
How do we feed these astronauts?
The list goes on and on. They may have done it before but you can bet your ass that the exact answers to these questions are not printed in a nice "How-to" manual nor will NASA's answers be the most economic or even most sound solution. My point is, try doing all that, today, with $100 Million dollars and see how far you get. I certainly wont be flying on such a craft.
Of course, but even basic physics will give anyone an indication of how much energy is needed to propel a craft into orbit and at least indicate, just how difficult some aspects of space flight really are.
I still don't think it's as difficult as people think it is to get into orbit - or to the moon
Do you care to enlighten us mere mortals as to how you plan to accomplish this with $100 Million? Don't start talking about Space Ship One because even Burt Rutan has stated that the craft is not very useful outside of simply winning the X-Prize and providing valuable data for future designs, which in fact, must be radically different just to achieve orbit (and will also require substancial outside funding and investment, on the order of almost a billion dollars).
Please, take a basic physics class before you start telling people how it's not very difficult to get to orbit or the moon.
