Hello, I'm new here

Hello,

I'm new here.

Let me introduce myself, i am jmjlinux586,

and I use Mandriva Linux.

To see more about me see my http://jmjlinux.110mb.com/about.html

about page.

I would also like to say that I have a web site:Helpful Linux Links and

Piano links  http://jmjlinux.110mb.com

The purpose of Helpful Linux Links is to help people learn about Linux. Here you will find links about Linux Distributions, Installing Linux, Live cd's Linux Applications or Programs, Linux Forums, Linux articles and other Linux topics you want to learn about.

Yes I also have Piano Links on there.

These are the two things I spend my time on.

 

The other reason for this post is to say that

I am glad to see this site is back again, and

that I have posted a link to this site on my

site.

Thanks

Hello, my name is Eric

Hi, I have been using Linux since 2003.  I have taken a couple of Linux administrators courses at a local community college.  I learned from Jeremy Anderson,,,,I consider him to be the Guru of Linux. 

 

Since taking the courses, I have spent the majority of my experiences at figuring out how to use Linux on Laptops, realizing that if Linux is to become mainstream, it needs to move past the traditional desktop, but to laptop.  Which leads to issues in the proprietary drivers, and configuring wireless.  Which I have gotten fairly proficient with.  I am now finding out an issue with some of the video cards...as I have duplicate laptops...Dell 1501 Inspiron AMD 1800 and a 1900  Dual-Core laptops...one will install Fedora, Open Suse, Centos, and Mandriva...and one won't...it will only take Centos with out any major issues.

 

I have been building desktops, and I have build a laptop...really I rebuilt a laptop because of how everything is limited with laptops....

 

Ubuntu Developer Network

Since I have never written about this here before, here's a little background.  The Ubuntu Developer Network is an idea that I have been promoting for the past several weeks.  I came up with the idea while trying to package an application for Ubuntu.  Much of the documentation was available, but it was scattered across Ubuntu's vast wiki system.  Many of the pages, while well written, led me in constant loops where I was left to figure out how to do many things.  While it was a good learning experience, I thought it could certainly be better.  I also felt just a MOTU section in the wiki was to narrow a focus to be much use to a first-time programmer.  This sparked an idea for a developer network, a place that could help people not only package an application for Ubuntu, but write software for and on Ubuntu.  

I began to look around the many different developer networks. and found that they were quite helpful -- far more in fact than the loose wiki page system used by the Ubuntu community.   MSDN (I know, don't even say it...), SDN, and others all had different tracks, all built for either different skill levels or different topics.  As a starting programmer, I went to the Visual Basic guides at MSDN.  Within about 5 minutes of installing the software, I had already made a simple web browser.  Really, it should be just as easy to learn how to use the tools and learn the programming languages.  The great thing about a UDN is the fact that it does not have to be hosted on the Ubuntu site, and many things can be linked to tutorials, application info on the wiki, etc.

For an example of how UDN would work, let's say I wanted to do Python programming on Ubuntu.  I would go to "udn.ubuntu.com" or something similar and see a main page, with the Ubuntu Developer News, latest video from the Ubuntu Developer channel on YouTube, and see links for different tracks.  I would pick the one for Python programming, which would take me to a page with different options:  Beginning Python Programming, Packaging Python Applications for Ubuntu, etc. I would click on the "Beginning Python Programming" link.  A page would load listing prerequisites (e.g. to complete this track you must install x and use Python 2.6, etc.), with links to additional resources that can be used (such as the book "Learning Python" by O'REILLY publishing).  The tutorial would then continue by showing how to use different tools for Python programming on Ubuntu.  Similarly, "Learning to Package Python Applications on Ubuntu" would lead me to prerequisites for building a package, then to guides on how to do it.  

That's the Ubuntu Developer Network in a nutshell.  I plan to write a formal plan and present the blueprint on Launchpad soon.  If you happen to like the plan, vote for it on the Ubuntu Brainstorm site!

 

How to configure your wireless correctly.

Every Distro has its own unique quirks about setting up wireless.

I have primarily used Red Hat Distros, such as Centos, Fedora.

However I have set up wireless on Open-suze, Mandriva, LinuxMint.

If you follow these instructions, you should avoid frustration and issues.

step 1. - enter terminal

su -

#yum update

# lspci -l

uname -r

step 2.  go to firefox, or your web browser of choice...sourceforge.net

http://sourceforge.net/projects/ndiswrapper/

ndiswrapper ( latest version is ndiswrapper-1.54) 

download and save to file...

step 3.

enter back to terminal

mv ndiswrapper-1.54.tar.gz  /usr/src

cd /usr/src

tar -xzvf ndiswrapper-1.54.tar.gz

cd ndiswrapper-1.54

make clean

make

su -

make install

ln -s /lib/modules/uname -r/build

(uname -r) is your kernel...centos it is currently

2.6.18-128.1.1.el5

cd /

su -

mk dir AA

 

 

Step 4. 

lspci --your driver...the best option is to go to your support site for maker of your laptop...such as HP, Dell, Toshiba...etc...

download and save as file the correct driver...generally this gets saved in your home file. 

make sure to move the file to a safe place...

I would ;   mv FILE NAME.EXE  /usr/src/AA ( you created AA in step#3)

cd /usr/src/AA unzip 

cd /

ndiswrapper -i   /usr/src/AA/DRIVER/bcmwl5.inf

modprobe ndiswrapper

ndiswrapper -m alias "eth1" >> wlan0

ndiswrapper -mi

ndiswrapper -ma

iwconfig....it should then list wlan0

cd /

cd /etc/modules.d

nano blacklist

enter at the bottom of the list : blacklist bcm43xxx

 

reboot

 

If you have a wireless Hot Key--- make sure you watch to see it light up.

 

step 4.  

http://linuxwireless.org/en/users/Drivers/b43

Linuxwireless.org has a great way to install.  You need the information from lspci.  

 depending upon your driver...it will determine what you need for a driver for wireless. 

wget http://bu3sch.de/b43/fwcutter/b43-fwcutter-011.tar.bz2
tar xjf b43-fwcutter-011.tar.bz2
cd b43-fwcutter-011
make

make install
cd ..
export FIRMWARE_INSTALL_DIR="/lib/firmware"
wget http://downloads.openwrt.org/sources/broadcom-wl-4.80.53.0.tar.bz2
tar xjf broadcom-wl-4.80.53.0.tar.bz2
cd broadcom-wl-4.80.53.0/kmod
sudo ../../b43-fwcutter-011/b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" wl_apsta.o
exit...
 
ifconfig...it should list wlan0.... 
reboot...and you should have wireless.... 
 
Potential issues:
 
wpa_supplicant...you may need to go to services...and start this service...it will then enable  you to connect to your wireless service...
 
again...each distro has its own hang up..but this should get your wirless working in almost all instances... 

 

 

 

When code becomes a hammer

Ted Dziuba wrote last week in The Register about the recent spat between the developers of two Firefox extensions, Adblock Plus and NoScript. He discussed how they both opted to engage in an escalating code war, instead of talking with each other and resolving their differences.

Dziuba's snarkiness aside, there is an important point to be made here. There is a tendency among people with technical skills to see every problem as a technical one, and seek out a technical solution. This is what the two extension developers, Wladimir Palant and Giorgio Maone, have done here: they each in turn changed their code so the ads on Maone's site would alternately show and not show. Each of them saw the problem as a technical problem, and solved it with code.

But some problems, specifically those related to disagreement between people, cannot - or should not - be solved with code. A technical solution, while tempting, might even cause more damage than good. The reason is simple: the other side would usually keep pushing his interests as well. He might implement a technical counter-measure, or maybe use a totally different tactic: use the law (or change the law), use commercial influence, buy off the opposition, etc.

Here are a few more example where some entrepreneurial spirit thought of a technical solution to a social problem:

Marketcetera Announces Major Upgrade to World’s Leading Open Source Trading Platform

 

 

 

Latest release of automated trading platform bolsters scalability and data segregation by user role, improves real-time P/L reporting

 

NEW YORK, NY & SAN FRANCISCO, CA - May 18, 2009, Marketcetera, the leader in open source platforms for automated trading, today announced immediate availability of the latest release of its popular automated trading platform, with four major new features to help traders scale, support multiple users and get deeper real-time reporting on profit and loss for intra-day positions.

 

Data volumes are exploding on Wall Street, with analysts forecasting equity options volume, for example, doubling annually in 2009 and 2010, and in return driving increased demand for automated trading platforms to help manage the volume. A recent survey by the TABB Group, a financial services market research firm, shows nearly half of the buy side considering a change in execution management system (EMS) this year, citing a desire to consolidate, integrate, customize, improve technology and lower costs.

 

"With market data volumes exploding, automated trading is becoming more prevalent on the buy side and across more asset classes, not just equities," said Graham Miller, CEO of Marketcetera. "This environment places tremendous pressure on investment firms to continue to make fast, intelligent trading decisions at ever lower costs per transaction. With the release of Marketcetera Version 1.5 and the benefits of our open architecture and powerful strategy research and development environment, we're fundamentally changing how traders can successfully meet these new challenges."

           

The Marketcetera Trading Platform's open and modular architecture designed to facilitate rapid deployment and ease of extension. Rich APIs including a built-in scripting engine, make it easy to extend the functionality of the Marketcetera Platform. Internal teams can develop custom pricing and risk modules quickly. Complex new trading strategies can be tested and implemented in minutes. And a foundation of open source technologies such as QuickFIX and Esper provide the performance of proprietary packages with the flexibility of a custom solution.

 

The major added new features in Marketcetera Platform Version 1.5 include:

 

  1. Real-time intraday position and profit and loss monitoring. The Marketcetera Platform desktop application, Strategy Studio, now supports real-time intraday position and profit and loss tracking and management on all trades around the clock.

 

  1. Simplicity and security for multi-user installations. Building on the existing authentication framework, the Marketcetera Platform now provides segregation of trading activities and strategies for traders and supervisors or risk managers.

 

  1. Level 2 and depth-of-book market data. Get more than just the best bid and offer. With added support for NASDAQ Level 2, TotalView and other depth-of-book market data feeds, Strategy Studio and strategy APIs allow liquidity seekers all the information in the marketplace.

 

  1. Strategy Studio - strategy agent integration. Now the Marketcetera Platform allows traders to directly deploy strategies on remote servers. Traders can manage multiple agents through Strategy Studio that may be running on multiple servers, offering new levels of trading scalability and control.

Make Ajax much faster with Tomcat Non-Blocking I/O (NIO) in its Advanced IO modules

Using Non-Blocking I/O (NIO) improves server performance drastically because of its efficient use of system resources (threads). The gain in performance is very noticeable in Ajax applications. It also lets you control system-resource usage on a server under pressure. This article explains how to optimize your server for performance during the handling of both Ajax and regular requests.
