Re: Speeding up a machine

>In the sense that my Chevy and an armored personnel carrier both serve >the purpose of transporting people. Comparing CMD.EXE and Konsole isn't anything like comparing a Chevy and an APC. It's more like comparing a tiny Hyundai's engine and Hummer chassis. It really doesn't make sense. CMD.exe/Command.com are shells, like, but greatly inferior to, bash/ksh/etc. It's possible to write a Konsole like tabbed application that would allow you to manage multiple instances of CMD in one window, or, if you're anything like me, cygwin's bash. >There is so much stuff I can do at a Bourne or Korn prompt > (much less bash) that in Windows would require a VB script > or a compiled binary to do the same thing. Speaking of cygwin, there's no reason you can't port those scripts over, nearly verbatim, to Windows. perl, bash, korn, python, et al are available in Windows as well, and they work great. -Sean Crago/MrZaius

I still resist the notion of any limitation between a programming language and the machine, because it is a dangerous trend to limit the developer from full, assembler-level access to all hardware. Otherwise you incrementally stunt his abilities, and that is sad. I am thinking about development fifty+ years in the future, when these issues are more mature, and from that perspective, the Java approach is incrementally more and more limiting to the developer. >> Java has cross-platform merits, but clearly, it was designed by the >> marketing department, not by the geek squad. > Java has cross-platform merits not because of the virtual machine, > but because of its extensive standard library giving abstractions > for most of what people need to do.

Java does have cross-platform merits because of the virtual machine. Your observations on libraries are keen, but are not the only reason that Java has cross-platform merits. We're both right: I quote from http://en.wikipedia.org/wiki/Cross-platform. As previously noted, the Java platform is an exception to the general rule that an operating system is a software platform. The Java language provides a virtual machine, or a "virtual CPU" which runs all of the code that is written for the language. This enables the same executable binary to run on all systems which support the Java software, through the Java Virtual Machine. Java executables do not run directly on the operating system; that is, neither Windows nor Linux execute Java programs directly. Instead, a special computer program called the JVM, or Java Virtual Machine, is run by the operating system, which in turn runs the Java program. Again, I'm fine with Java as a language, if only the virtual layer could be removed. >> If you can't crash a server, and crash it big with buggy >> inline assembler, how are you ever going to learn grace >> under pressure, which is a necessary component of any >> responsible world domination plan? ;) > You can't, or at least shouldn't be able to, crash a server > with mere userland code.

But it is incrementalism in the wrong direction, not toward freedom, and it removes useful tinkering ground from mature developers. Do not think that all geeks will always have the freedoms they take for granted today. Classlines are already being drawn. Be wise. Stake a claim in the ruling class because you understand the underlying issues. Not far in the future, kernels will be considered "finished" and stable, because hierarchical power structures will have consolidated around them, and will prevent innovation, which is a pattern easily measured by studying the social dynamics of any large religion: Initial Freedom followed by incremental imprisonment of its own followers, until they are killing each other over absolutely trivial issues. We must recognize we are building the foundations of a future which will not always be as free as it is now -- unless we look at these deeper issues and their long term consequences. I prefer the geek to have full ability to crash the box -- and the wisdom and ethics not to do so; not a firewall of technology preventing him, but a firewall of ethics. It's like the logic behind the 2nd Amendment to the Constitution. You seem to prefer removing power from the geek by limiting him, rather than relying upon the reputation economy to inspire geeks to do better, which is more perilous, but better in the end. The original rant remains standing: On a philosophical level, virtual machine layers limit the geek. Some geeks like that. This one prefers freedom. -Jared

FC4 and tzdata
by Jon Moss 09 Mar '07

09 Mar '07

Since I've been up to my eyeballs in Microsoft DST issues at work, I thought I'd take a breather and make sure that my Linux servers were okay with the upcoming change. I was pleased to note that my oldest server (running FC2) was fine. My newer server, running FC4, had a problem. After reviewing many different blogs and postings, I thought I had it figured out but now I've completely messed up the Central Time Zone files in /usr/share/zoneinfo/America such that I no longer have data for the Central Time Zone. :) I've set the server to use America/New_York (copied it over /etc/localtime) so I'm at least running in the Easter Time Zone. I would like to re-install or re-update the tzdata RPM package, but it won't let me because it's already installed (and I can't uninstall it because glibc depends on it). How can I force it to re-install? Also, since the Fedoral Legacy Project has shutdown my yum no longer functions or doesn't have a repository it can access. Any ideas on how I can get connected to one of the mirrors?

Newbie Command Line Tutorial
by Jonathan Hutchins 08 Mar '07

08 Mar '07

What's your favorite tutorial for command line newbies? I usually point to http://tldp.org/HOWTO/DOS-Win-to-Linux-HOWTO.html , but that presumes some basic knowledge of the DOS/Windows command line.

Installing Kubuntu 6.10 on VMWare 6.01 running on WinXP SP2 workstation
by Jon Moss 08 Mar '07

08 Mar '07

I was so excited yesterday when a colleague of mine installed VMWare on my development workstation at work. Now, finally, I could install Linux at work! So I grabbed the Kubuntu 6.10 ISO file (downloading it to the aforementioned workstation) and read the VMWare help file about installing other operating systems. I thought everything was going great because I was seeing the Kubuntu logo and it started the install. However, it reaches a point (even after the second try when I told it to do the install in safe graphics mode) where the screen expands horizontally and I can't see what it wants me to do anymore. I get a shadowy stretched image but not enough to decipher what happens next. Any thoughts?

http://rute.2038bug.com/ http://linux.2038bug.com/rute-home.html They removed it from sourceforge, where it used to be hosted. It is a very good general set of docs on Linux and a jumping off point to other learning. >-----Original Message----- >From: Jonathan Hutchins >Sent: Wednesday, March 07, 2007 11:24 AM > >What's your favorite tutorial for command line newbies? > >I usually point to >http://tldp.org/HOWTO/DOS-Win-to-Linux-HOWTO.html , but that >presumes some basic knowledge of the DOS/Windows command line.

All, If you have previously signed up for the kcaug mailing list please take a moment to do so again at kcaug.net. Short story, hard drive died and backups disappeared. ;) Sorry for any inconvenience, and I look forward to more Asterisk discussions! I've also revamped the site to include blog syndication from users in the KC area. If you have a blog and occasionally write about asterisk let me know. -- Kyle Sexton
