Submission + - How to find which process is eating memory | Linux (go2linux.org) 1

Submitted by ggarron
ggarron writes: "If you are running out of RAM on your Linux system, you will want to find the culprit in order to solve the problem, either by reconfiguring the RAM-hungry application or by stopping it."

"We'll use ps, awk, head and sort with a pipe, to find out which application is consuming our RAM"

"List running processes ordered by RAM usage"

ps aux | awk '{print $2, $4, $11}' | sort -k2rn | head -n 20

Submission + - Interview with Debian Developer Raphaël Hertz (go2linux.org)

Submitted by Anonymous Coward
An anonymous reader writes: "If you could spend all your time on Debian what would you work for? — I would try to fix the 400 bugs filed against dpkg."

"What’s the biggest problem of Debian?

"Our project identity is somewhat minimalistic. It evolves around the social contract and the Debian Free Software Guidelines. Both documents answer the question of what we’re doing but we lack a clear answer to the question of how we’re supposed to work towards our goals. It would be great if Debian could agree on some principles concerning topics like goal setting, collaboration, team work, politeness, respect. We could then advertise those and build on them while recruiting volunteers.

"What’s the biggest problem of Linux?

"I’m always annoyed when some new hardware doesn’t work. It’s painful to have to google around to find out a solution. Sometimes you need a newer kernel, sometimes you need to build custom modules for your kernel, sometimes you need a firmware for a driver that you already have, sometimes you need a newer version of Xorg, etc."

Submission + - USB stick for Techs 1

Submitted by SmoothBreaker
SmoothBreaker writes: Slashdot readers, I'm working on a project for both my own company and my current full time employer, where we will have a usb stick loaded with apps and utilities to be used on systems to set parameters, troubleshoot, etc. However, the desired level of control is to restrict the drive to write permissions and allow the programs to run, but require only certain users to delete data from them, to prevent accidental deletions of the files and yet be ubiquitous across user machines and any domain. I havent found anything that seems to quite address that level of control. Am I missing a good solution, or is this only a pipe dream?

Submission + - Arch Linux reviews

Submitted by
An anonymous reader writes: Arch Linux current version is 2010.05, but Arch Linux is a rolling release distribution, so this version is only the snapshot of the Installation image, Arch Linux is suited for the experienced Linux user, but the mid-experienced user may also try it.
There are a lot of good reviews of it, I have found these two really interesting ones.

Arch Linux Review Which basically covers a good general description about its philosophy, the rolling release, the community and other topics.

Arch Linux 2010.05 [review] Which covers mainly the installation process, and has also step by step screenshots, for the KDE installation.

Submission + - 76% of big business is getting more Linux servers (networkworld.com)

Submitted by Cussin_IT
Cussin_IT writes: Networkworld has an article on the uptake of linux servers.
According to the article, 76% of large organisations are planning to add linux servers, while only 41% are adding windows servers (presumably this means 17% are adding both) over the next year. And in the next 5 years the percentage adding windows servers drops to 21%.

Submission + - Investors Bet Small On Social Startups (itworld.com)

Submitted by itwbennett
itwbennett writes: According to data released Wednesday by research firm CB Insights, venture capital investments in Internet start-ups stalled in Q3 (total number of deals was the same as in Q2, while the total dollar amount dropped). Blogger Chris Nurney has pulled out some of the highlights: California netted 44% of all deals and 50% of investments; The top Internet sector was social (14% of all deals, 11% of all VC money); Gaming 'falls of the map', with no deals in Q3. 'One thing that stands out as you look at the data is that the average investment in a social networking start-up is smaller than the average investment in more enterprise-critical sectors such as business analytics, data storage and cloud computing,' says Nurney. 'So social is big, but investors are placing smaller bets.'

Journal Journal: First Journal entry

Journal by ggarron
This is going to be my "Hello World" /. journal post. I did not know about this, and that is kind of weird, as I am a /. reader since three years ago. I have even submitted some news to the stream. But that is old story, now I know it, I will try to share some of my thoughts here, and enter this great and exclusive community. Thanks Slashdot for the opportunity.

Submission + - ssh public key only authentication (go2linux.org)

Submitted by ggarron
ggarron writes: OpenSSH key public key authentication, let users log into server without the need to use their user's passwords.

It is possible to disable any other form of login into server, and let available only authentication based on ssh public key.

What is achieved, using this method is to avoid password break by brute force attacks.

For this method to work, three steps should be taken.

        Create a pair public / private key ssh
        Disable root login in the server
        Disable password login for any other user in the server

Submission + - Sun (Now Oracle) VirtualBox: An Observation (linuxjournal.com)

Submitted by ggarron
ggarron writes: "Back to the issue: for my virtual machine, I used to use VMWare, but I switched over to Sun (now Oracle) VirtualBox several years ago. Generally, I’ve been quite happy with VirtualBox.".....
"However...

Today I ran up against one of those apparently persistent, long-lived bugs in VirtualBox that threatens to derail my productivity for at least a few more hours. Here’s the background: I created the VirtualBox VM that I am currently using about 3 years ago. At that time, it seemed like a good idea to use a fixed 10GB virtual disk drive for the XP C: drive in VirtualBox when I was building it. Don’t ask why, it just seemed like a good idea at the time."

Submission + - New branch on Debian? (go2linux.org)

Submitted by ggarron
ggarron writes: "It is well known on the Debian Community that the Stable version, is aimed for production environments mainly focused on stability and security, but not in having the latest packet versions. Therefore desktop users usually use Testing version for desktop environments, but this leads to some problems, as it is not intended for normal use, but for development and testing of the new stable version..."

"The solution, a new branch that being based on Testing..."

Submission + - Can Debian offer a Constantly Usable Testing distr (raphaelhertzog.com)

Submitted by ggarron
ggarron writes: Debian’s “testing” distribution is where Debian developers prepare the next stable distribution. While this is still its main purpose, many users have adopted this version of Debian because it offers them a good trade-off between stability and freshness. But there are downsides to using this distribution and the “Constantly Usable Testing” (CUT) project aims to resolve those. This article will present the project and the challenges involved to make it happen.

Submission + - Two new Linux Distributions I have tested (go2linux.org)

Submitted by ggarron
ggarron writes: Some days ago I have started testing Linux Mint Debian Edition and Archbang.

ArchBang is an Arch Linux based distribution, I think it is inspired in CrunchBang which until now is based on Ubuntu, and switching to Debian.

Linux Mint Debian Edition, it is a complete different beast. Based on Debian Testing, LMDE in no ways tries to be a lightweight distribution, it is a fully functional Linux Desktop distribution, ready to defeat Ubuntu, Fedora or PCLinuxOS.

Includes a video comparing how they look like

Submission + - Quo Vadis Linux? (go2linux.org)

Submitted by
An anonymous reader writes: According to the author, internal problems in the Linux community are slowing down, if not stopping the Linux market share in the Desktop area.
He compares the community with a corporation, that needs a board to establish the strategy.
As he states, it seems that all the community has the same goal, but not the same strategy, therefore, the success is still far away.

Submission + - Worm in wild is targetting industrial controllers (nytimes.com)

Submitted by
Kevin Stevens
Kevin Stevens writes: "In a story from the NY Times that sounds like something out of a Dan Brown novel, there appears to be a worm in the wild developed by an intelligence agency that targets specific industrial controllers used in Iran's nuclear weapons program. If that isn't sensational enough, looking at the strings inside the worm's code reveal that the project's internal name is a reference to a biblical story about the Jewish people pre-emptively attacking the Persians who were plotting against them."

Why the Revolution Will Not Be Tweeted 305

Posted by Soulskill from the lost-amid-breakfast-descriptions dept.
An anonymous reader writes "Social media is ill-suited to promoting real social change, argues Malcolm Gladwell in this article from The New Yorker magazine. He deftly debunks conventional wisdom surrounding the impact of Twitter, Facebook and other social media in driving systemic social change, comparing them to the organizational strategies of the 1960s civil rights movement. For example, the Montgomery bus boycott, he argues, was successful because it was driven by the disciplined and hierarchically organized NAACP. In contrast, a loose, social-media style network wouldn't have sustained the year long campaign. He concludes that social media promote social 'weak ties' which are not strong enough to motivate people to take big risks, such as imprisonment or attack, for social change."
