This tutorial is the second in a two-part series on locking your Linux machines down to streamline the associated support and administration processes. In this tutorial, you learn how to configure the Linux kernel to execute only signed binaries. This tutorial expands on the groundwork laid in Part 1, which gave some good reasons for keeping Linux's propensity for customization under control and took the first cautious steps toward locking down a standard Linux distribution to prevent spurious user changes to the baseline installation.
Ying Huang posted a new version of his hibernation patches that utilize kexec noting two changes,"1) the kexec jump implementation is put into the kexec/kdump framework instead of software suspend framework. The device and CPU state save/restore code of software suspend is called when needed; and 2) the same code path is used for both kexec a new kernel and jump back to original kernel." Andrew Morton noted that he was still interested however didn't intend to merge the patches right away.
In our house, the refrigerator door is where we post the family calendar, showing our family and friends' birthdays, school terms, and important events, along with public holidays. We create the calendar using a nifty command-line program called PCAL, which produces a standard one-month-per-page calendar with each day in a separate box. It resembles those mall-stall calendars, but the important dates in our family's life are highlighted.
One Course Source has announced its first annual open source conference, set for Oct. 3-4 in San Diego, Calif. The organization says the "One Course Source - Open Source Conference" (OCS-OSC) aims to "[address] the growing demand for alternative technology solutions that cost-effectively support and sustain the corporate IT environment". They are currently seeking Open Source professionals in the San Diego area to present topics on their area of expertise as it relates to Open Source technologies in the corporate IT environment.
Reader-submitted nominations were at the heart of the annual "Linux and Enterprise Open Source Readers' Choice awards," revealed at the recent Enterprise Open Source Conference & Expo 2007 in New York. Notable winners include Ubuntu (Linux distribution), Sendmail (email server), and Evolution (productivity tool), conference organizer SYS-CON Media announced this week.
I never found good documentation on upgrading/compiling Linux kernel in Debian, Most of the time I stuck in between and my running libs gets corrupted, then same story; Put new hard disk, Install latest Debian, mount old HDD and copy all the contents. After reading documents in net, I setup my step-by-step Linux kernel up-gradation (Bash Scripts) in Debian. Up-till now I upgraded more than 5 Debian kernels without any problem.
We bring the advice of experts straight from San Diego to your desktop. Red Hat Summit 2007 collected hundreds of Linux users all in one place–many of them experienced Red Hat Certified Engineers® (RHCE). And somewhere between all those smart people walking around–and our video crew shooting footage–the idea for some video tips was born. This tip is from Richard Ray. Look for more in the coming weeks.
I've already written two Pardus reviews -- 2007 Beta 2 and 2007.1. So it's time for a review of 2007.2 Caracal release. In this article I will focus on the key changes and my personal thoughts concerning this interesting distribution.
Now that real-time Java virtual machines support scoped memory, defining common patterns for scoped memory usage can improve developer productivity. These patterns reduce the need to understand or work with scopes directly by providing scopes' core functions with less complexity.
No, it’s not the “Top 100,” nor does this list contain the “only” 100 open source downloads you should consider – there’s a big ocean out there, so please keep swimming.
The Software Freedom Law Center's first Annual Legal Summit for Software Freedom October 12 includes a closed private meeting in the morning for key open source attorneys and a series of educational lectures in the afternoon that will be open to other interested lawyers as well as the general public.
The single biggest argument against a smooth migration to one of the popular desktop Linux distributions is the belief that key applications are not available on the Linux platform. However there are a multitude of fantastic open source alternatives that are easy to install and free to use.
Microsoft's plans of having its OOXML document format accepted as a national standard were thwarted by a conclusive vote against the move in a meeting yesterday.
KDE's new technical documentation library, TechBase, hit an important milestone today when it served up its one millionth page. In step with the KDE 4.0 development cycle, TechBase is rapidly maturing into a central hub for high-level technical information related to KDE and the Free software desktop.
Two new documentation directories were merged into the upcoming 2.6.23 mainline kernel, containing translations of the HOWTO and stable_api_nonsense.txt documents in Japanese and Chinese. Greg KH explained, "here are some patches that add some translations of some procedural documentation files to the Documentation/ tree." Regarding some of the concerns that were expressed with merging translated documentation into the mainline kernel tarball, Greg noted, "these files change _very_ slowly over time, and are quite easy to keep up to date by the translators."
Gutsy Gibbon Tribe 3 is the third alpha release of Ubuntu 7.10, and with this new alpha release comes a whole host of excellent new features. Note: This is still an alpha release. Do not install it on production machines. The final stable version will be released in October 2007.
Linux vendor Xandros has bought privately owned open source email and calendaring provider Scalix for an undisclosed sum. Scalix president and CEO Glenn Winokur will stay through the transition only and become a member of the Xandros advisory board. Vice president of finance Walter Lim will also leave the company; the sales support staff and the staff of engineers - a total of about 13 people - will all stay on with Xandros, told Xandros CEO Andy Typaldos.
Playing around with radio-frequency transmission and reception used to be restricted to those of us with hardware skills. That has been changing for some years, though, as processors get faster and software techniques advance; now, many radio transmitters and receivers are built with simple (but flexible) hardware. The hard work of generating the signal to be transmitted is done in software. Some wireless network adapters work that way now, as do a number of other devices. There is a well-advanced project - GNU Radio - which enables experimenters to do amazing things with software defined radio (SDR) systems.
The alpha 1 development release of Damn Small Linux (DSL) 4.0, which hit the Net on Tuesday, is "a very different version" that includes a number of features requested by users on the DSL forums.
