Problemas com libxml2.so.2 no fedora 12 32 bits

I managed to solve this myself. I found that there were two installations of libmxl2.

 

Code:

 

# locate libxml2.so.2

/usr/lib64/libxml2.so.2

/usr/lib64/libxml2.so.2.6.26

/usr/local/lib/libxml2.so.2

/usr/local/lib/libxml2.so.2.7.6

 

I then deleted the old version and created a symbolic link to the new:

 

Quote:

# ln -s /usr/local/lib/libxml2.so.2 /usr/lib64/libxml2.so.2

Os "300 do Largo" se fizeram "Cem Mil" Ou: O templo da lei expulsou a legalidade e escolheu o crime

Por Reinaldo Azevedo

Enquanto escrevo, na madrugada de domingo para segunda, o Manifesto em Defesa da Democracia, lançado no dia 22 de setembro, está a 1.557 assinaturas de atingir a marca histórica de 100 mil signatários. Clique aqui  (http://www.defesadademocracia.com.br/) para ler, assinar e divulgar.

Eis uma idéia que mobilizou o Brasil. Na manhã daquela quarta-feira, impedido de liderar a manifestação no interior da Faculdade de Direito do Largo São Francisco, o jurista Hélio Bicudo leu o texto— um mísero microfone lhe foi negado — em frente ao prédio da faculdade e foi seguido, frase a frase, por quase 300 pessoas. Mas valeu a pena. Os 300 do Largo se transformaram em 100 mil. As dificuldades contribuíram para revelar a essência daquela oração em favor da democracia: um ato de resistência. Segue um filme feito com um celular. Volto em seguida:

Trata-se, como se ouviu, de um manifesto em favor do estado de direito, que cobra dos governantes o respeito às leis e à Constituição. Duas semanas depois, os petistas Dalmo Dallari, professor da São Francisco, e Marilena Chaui, do Departamento de Filosofia da USP, lideraram um ato ilegal no interior da faculdade, na Sala dos Estudantes, em defesa da candidatura da petista Dilma Rousseff, afrontando a Lei Eleitoral.

Para os legalistas, nada, nem a lei.
Para os “ilegalistas”, tudo, menos a lei.

Agora, sim, o manifesto, com toda a sua clareza. Volto para encerrar.

Os que seguiam a lei tiveram de falar fora das arcadas que simbolizam o direito, e aqueles que afrontavam a ordem legal puderam profanar o templo. As duas manifestações dão testemunho do nosso tempo. Os que celebravam a democracia denunciavam a mistificação; os que celebravam a mistificação estavam denunciando a democracia.

10 Design Tips for a Business Web Site

I get this question asked all the time: "What do you think of my super duper galactic ninja in action business site?" In all honestly I really dislike this question because the expectation is for me to say "Wow, great site, nice design, and great layout."

Don't get me wrong, I do give honest praises for the design and the creativity especially if the person creating the site doesn't know that much about web design.

The person usually hears the hesitation in my voice and asks, "Well what's wrong with it?" To which I reply "I look at your web site and I have no idea what you do, who you are or how to contact you."

Your web site is the new resume. The World Wide Web is the new digital newspaper. Here is an interesting fact: 83% of all recruiters Google their applicants and 43% discard applicants based on what they see. If your web site suffers you suffer.

Here are some of my personal 10 Design Tips for a Business Web Site to avoid your visitors guessing what you do and who you are:

1. Before the designing begins you should have a good outline of content that will be on the site for its launch. How many pages, what those pages will be, navigation order, color scheme, etc.

2. Content should include:

- A full complete description of your services or product. Your content should answer those basic questions mentioned above - who are you, what do you do, how to contact you.

- A way for people to contact you - email address, contact information page, or a contact form.

- Post comments or feedback from customers who have bought your product or used your service.

- Images of related to the content. It could be as simple as stock photo or more preferably a photo of your product or services. In other words, your images should reflect who you are and your services that you represent and should have appropriate ALT tags.

- Post a page of other businesses you have worked with. Link to their site. Ask to get a link back to your web site.

- If your site is large with lots of content, add a search function. Some search engines like Google will give you a free web search and the code you can just plug in to your site.

3. Avoid overloading your pages. Web pages that a visitor must scroll down more than 2 times should be broken up into separate sections. Visitors jut won't read that much.

4. All pages should contain meta keywords and descriptions, and descriptive page titles. Meta tags are contained in the HTML code. Go to Wikipedia for examples and how to's

5. Avoid over doing the design. Keep it Simple. Don't mix and match colors. Use a design wheel to organize your color scheme.

6. Avoid gizmos, widgets and gadgets. Just because you know how to make text blink or scroll on your home page doesn't mean it is a good gizmo to have.

7. Avoid using Flash intro pages. I might be going against the grain here, but in my opinion Flash intros are a distraction and a detractor from your web site.

Visitors want to see and read about what you do and not a flashy advertisement.

8. Write and post articles relevant to your products or services. This will fill out your web site, keep visitors interested, and keep visitors coming back.

9. Don't let your site get stale. Keep adding to it in an organized way. Introduce new articles, press releases, new training, etc. A web site needs to be continually updated.

10. Use spell check and grammar tools in Word or other editors before you post your content.

Why virtual worlds are important for business

Posted on 10 August 2010 by daleinnis

 

(“Ooh, an important-sounding weblog entry! Can we put in pictures of kittens?”

 

“No, no, this is important grown-up stuff! No kittens!”

 

“Maybe just at the end?”)

 

There is a ton of debate and discussion and information Out There about why virtual worlds are, or aren’t, or might someday be, important for business. Important, that is, to people who are wearing their money-making hats to know about, or to use, or to invest time or effort or money in.

 

There are a lot of smallish reasons that virtual worlds are important, today, for various businesses in various senses. They can fit cost-effectively somewhere between teleconferences and face-to-face meetings for some purposes; they can be at least potentially effective education and training platforms in some use-cases, and so on.

 

But I don’t want to talk about any of those reasons right now. I want to talk about a much bigger, if somewhat speculative, reason.

 

Virtual worlds are important for business, right now, because they are going to be extremely important, for just about everyone, eventually.

 

I believe, in a way that I can’t prove but through intuitions that I’ve come to trust over the millennia, that in the medium term virtual worlds are going to transform the way that we think of and use computers, computing, and information, and the ways that we interact with the world and with each other, in significant ways. At least as significantly as, for instance, the internet, or mobile phones, have done recently.

 

Even if I’m only halfway, only one-quarter, right about that, there are going to be some huge revenue streams associated with virtual worlds, and there are going to be moments at which pretty much any business that’s out there doing stuff is going to be in a position to capture, or to fail to capture, some part of one or more of those huge revenue streams.

 

In order to have a good chance of making that capture, a business organization is going to need to have enough people who, when an opportunity related to virtual worlds appears, will be more likely to think “hey yeah, that could work”, rather than “isn’t that that porn thing I saw on CNN last year?”.

 

So this doesn’t necessarily mean that a business should, today, be moving their weekly manager’s meetings into Second Life, or that your average high school drama class should have their own OpenSim region to meet in. (Those things might be true, or false, but this particular thought isn’t about that.)

 

What it does mean is that a business should have people who use virtual worlds. Who aren’t afraid to reveal the fact to their management. Who maybe even try using the technology for a business-related thing now and then. Maybe an IT guy who runs a little clump of four OpenSim regions on a spare server in the corner, and gives accounts to whoever happens to ask. Without getting in trouble for it.

 

And IT businesses, in particular, especially in software and especially in services, should have some pilots going, some studies. Maybe they’re on the shortlist to be cut when revenue is down, but they should be there. In the corner of someone’s eye. Being worked on in what’s left of the skunkworks. Being brought up in the last five minutes of executive briefings, under “ad-tech activities”.

 

The short-term benefits of virtual worlds have, I think, sometimes been oversold, and that’s led to us riding the usual hype curve more than once.

 

But if the long-term effects are anything like what I think they are going to be, businesses are well-advised to have, as well as any short-term stuff they’ve got going on with the technology, a culture in which the thought leaders have an eye on virtual worlds, are playing with them, and working with them. And management knows about it and is cool with it.

 

’cause, ya know, we won’t be selling buggy-whips over the counter forever…

Fix mingetty high CPU usage

Develop with Geoff at GoSquared

If like us you've been noticing decreased SSH terminal responsiveness on your server recently, or high CPU usage by a process called "mingetty", you'll want to know why this process is eating up your valuable CPU time and stop it doing so!

The Problem

mingetty_high_cpu

For those of you who don't know, mingetty is, as the manual page puts it, "a minimal getty for use on virtual consoles" - it is the process that handles the activity of your virtual console (like PuTTY). If mingetty's CPU usage is high, and/or your console responds slowly (particularly while running certain programs like top), a likely reason is that your utmp log file is getting large, and thus opening and writing to this file becomes resource intensive.

The Solution

Simply delete/move your current utmp log and create a fresh empty one. We moved ours:
mv /var/run/utmp /var/run/utmp.BAK
touch /var/run/utmp

That's it! Let's see if this has solved the issue:

CPU usage level

Hooray, it worked! Our CPU usage has now evened out to an acceptable level. You can check the CPU usage of mingetty by typing "top" into your console.

The utmp log contains information on all logins to your console, so you may need to repeat this step every now and again to prevent this happening again. Although you should keep tabs on who is logging into your system at all times, you could also just remove the /var/run/utmp logfile completely so you don't need to keep repeating this method.
