It shouldn't matter, especially if there are things such as JDBC, ODBC and other technologies of the sort being used. I have ported 2 HUGE applications from Oracle to PGSQL, and both went over without so much as a hitch. Even the Oracle procedure language went over in a snap.
the idea behind the clustering technology is it doesn't have to scale, you can add more boxes into the cluster and thats your scalability. I don't want to go off comparing database technology to something like distributed.net, etc. But, things such as queries are naturally broken down into simple tasks that are easily distributed across multiple machines.
if their cluster solutions works as well as the rest of the their software, it shouldn't be a problem.
Regarding Postgres, your claims are pretty weak. I have been using it for about 4 years and have never 'lost data'. Besides, isn't that what backups are for?
Perhaps Sun should announce their commitment to PostgreSQL.
*ROFL* - N o kidding!! Thats just how this sounds. To me it, at first glance, it may appear that oracle could be canabalizing their own product. If Linux is good enough to replace Sun kit, why isn't PGSQL good enough to replace moderate database requirements? What an interesting time we live in!
that was supposed to be 8i, and Dell was going to provide the hardware I believe. (Dell or Compaq, I forgot...) but basically Oracle had their own kernel layer that basically acted as the OS.
My guess is, as they got further into the game, they realized that they wouldn't be able to compete with any level of scalability the performance of Oracle on Sun. The One Widget to rule them all! *cough*
SIMPLY CHECKING TCP FLAGS IS NOT STATEFUL INSPECTION!! It's sometimes called stateless inspection and it means that a decision to pass or block a packet is decided on the characteristics of that packet alone.
Well, based on what you just said.. I still am ok. My rules basically states, only allow the packet into the state if it a) meets the port/proto requirements, b) meets the TCP Flags (S/SA). You seem to know what your talking about , so I am asking.. wouldn't that block a FIN/ACK scan through the firewall, being that the state wouldn't be established unless you met the criteria?
Also, OpenBSD's installation process can be intimidating the first few times through. Where Free makes it easy, Open makes you think about disk partitioning and other low-level issues.
Without sounding like an elitist, (which I am clearly or qualified to be), though the instalation was a bit awkward, it was direct and forward. After getting it installed, it was VERY easy to setup the configuration. All you really have to do is follow the instructions on the website. I had a machine setup in 2 hours (downloads and all w/floppy based install), after never touching the distro before thats not bad. Within 3 hours (and another helpful howto) I had the box hardened. Before the end of a long working day I had a VERY impressive set of rules setup to block various types of traffic, I understdood the difference between a stateless and statefull firewall and most importantly I understand why all the rules in my PF config where there.
I just find it nice knowing that there OBSD crew is working overtime to help me sleep better at night. At this stage in my career, if I am using and deploying open source solutions.. my judgment and credibility is on the line. I can't blame it on Scott or Bill if something goes wrong.
To be honest, if you are just using workstation apps, and not really using it for anything like a nat box, or the 'server in the closet tha never gets turned off' , it's probably not worth your time. The nice thing about playing with it, you get a feel of something different, which is a good thing. Linux,, redhat, is not the end-all be-all of server configurations.
I had a freebsd box sitting my in closet for about 18 months, until I got bored with it and install openbsd. BUT, I don't really do any xwindows stuff on it.. basically web serving, outgoing email gatway, nat, proxy, and the place where I build my Python programs and scripts.
I guess to summarize my experience, *BSD is not a workstation supliment, but more a compliment. It will sit there and do it's job without much headache. Thats good enough for me;-)
try open bsd. I am running it on my nat firewall (cable) and it runs in very modest settings. (I am running on a p100 w/32 megs ram and base install was 60 megs). You can install it from floppy disk over ISDN in an afternoon. (Look at the web site www.openbsd.org for install howto).
A) if you where to really setup a firewall to battle attacks/dos, etc, I would recomend OpenBSD. Second, you can compile into the kernel IPFilter which does support a stateful firewall configuration as well as acception and denyal of TCP packets based on the flag (SYN/ACK/FYN) etc. Once the rule has been accepted, the end packet stream is accepted into the state. I believe this is the same thing as syn-cookie, only better.) I hope someone reading this will give a bit more insight into the issue, because IANAFE (firewall expert).
In my experience the IPF and PF firewall configurations are the most simple, flexible and powerful to use, and can be found on freebsd and openbsd and probably the others.
Why not just buy a damn Athlon +++++ whateever system. At least I can be sure my binary only applications would work (ie. Java, Games, drivers, etc). Yes, in an open-source-only world, thats cool...
If I HAVE to have a risc-based work-station I would rather do it on Solaris. You can pickup a sun-blade very cheep, throw in some ram and you have a great unix workstation. It will run all the crap you would want to run on linux, including linux itself.
If I want to use a PPC platform, I personally will buy an Apple.
I use it mostly for development and as a unix admin workstation. I hack around with python and objective-c and even play Retrun-to-cstl-wolfenstein on it.. I imagine that I will be using it for another 8-12 months before it gets retired as a server or nat box (Which would replace my wifes old nappy-iBook (think toilet seat)). The cool thing about the iBook is , with exception of a huge hard disk.. it does everything I need just fine for a unix box. I setup DNS , apache for serving MP3's to friends and now I can actually turn off my linux machine when I am not using it. That means a nice quiet little server that makes almost NO noise, runs unix, configured the BSD (ipfw) firewall and handles my DSL nat just fine for the rest of my machines at the house.
I find myself upgrading my PC about once every 12-14 months, I expect to get at least 2-3 years out of my G4 (as I almost have done with my iBook)
I thought the same thing, for a few days.. until I just bit the bullet and made myself go through the little tutorials, etc. Now I am hacking away on some low level NNTL libraries to write the news-reader of my dreams.:) It's very nice once you get used to it, and if you take the time to actually get used to it.. it will probably make you a better programmer in any language you chose to code in.
I never realized how important the GnuStep movement could be until I took the time (one afternoon) to learn Objective C. It really is everything -I- could want from a language, with the only exception of NSStrings feel a bit clutsy to use after using python and java for so long.
If apple continues to break ground in market-share, and attracts more and more commercial development maybe we will start to see OSX ported GnuStep applications.
Maybe this is it. Show her how to dial up with the modem, use launch the email client and web client and find a version of AIM and there you go. I imagine that because it's UNIX(like), you should be able to run it non-priviliged without problems or fear of someone else messing it up.
Has anyone tried running this on slow hardware? (Such as a P133 or something w/32 megs ram?) How does it fare?
Some day I hope that we have a polition that has the balls to say: 'We [invaded/bombed/whatever] this area to protect the interests of Oil for our country. Our lifestyles depend on this Oil, and until it changes thats why we do it.'.
I feel like thats basically the truth. Maybe when we as citizens and consumers are ready to change our habbits, maybe things in the world will change.
Unfortunately such honesty is impossible in our political climate. Unforunately it's going to take an epidemic to change our unsatiable consumption for Oil.
We have the same problems in going out to market. We face customers that want to control their own destiny and not completely give up control of their core business.
I believe that unless the technology is a complete commodity , no company is going to be excited about signing up for something thats subscription and reley their business on it.
TWM? That fancy prideful window manager? Feh. No, you want UWM not one of those fancy re-parenting window managers.
*LOL*
Thanks for the insight. I agree, there are some issues that I hope they can work out. I don't know if it's coincidence, but I wrote something similar the other day for my digital pictures. (I have about 2000 of them). After backing them onto CD, I moved them onto my linux box using this software
PHPNuke + Gallery (http://gallery.sourceforge.net).
It's great even for just local managment. It runs in apache/php so it would probably even work on your mac, though it has a few graphics library dependancies you might have to go fetch/build. (I still don't understand why they didn't just use imagemagick for their graphics conversions).
Anyway, I have put all ~2k images into the that software and it manages it great (even nested albums, etc).
Henry Ford said the same thing about the first car. Basically it was a Tractor high-bread that will allow people to drive the store in the same vehicle after plowing the fields.
I happen to appreciate the elegance of something like OSX. It's out of my face so I can get the work I need done, done quicker.
The rumors about it being slow or buggy are just plain fud. They have fixed almost all of the anoying problems after version 10.1 and it's just getting better.
I find that I am actually able to do the things using the tools I am used to (Unix/GNU tools that I am used to such as VIM, wget, Lynx, php/apache, etc.) I can also play games (Wolfenstein) that I love, and co-habitate with my co-workers that are a MS Office establishment.
I don't know how you can say that interface improvments are regressive. The UNIX/Linux world would still be using TWM if we all kept that mentality.
My wife has a G4 466 at home and I must say, with ~300 megs ram, it's a little snappier than my Windows XP Pro machine (PIII 766) at work with 700+ megs of ram.
They have really come a long way in the last release and it seems to just keep getting better. I am quite impressed. Wolfenstien (multiplayer) was a little slower than my machine, but I have a GeForce2 and she only has a Rage 128, so that is understandable.
If the mainstream games start comming out on Mac I will definately jump to that ship. You ought to play with the new version of OSX 10.1 if you get a chance, it surprised me how much of an improvment it was over 10.0

Nope.. sorry. too slow and windows is way to bloated for the memory spec of that machine , especially as a guest OS.
Also, VMWARE is i386 only (binary remember).
