Javatm binary kernel support for linux v103
Bringing you the latest news from the Linux World. Dedicated to keeping Linux users up-to-date, with concise news for all interests. Leading items Linux Expo '99 is now history. Congratulations are due to all involved for running a high-quality show. Attendees at the Expo seemed to be generally happy with what they found. Some of the technical sessions were truly excellent.
Please see our Linux Expo page for our coverage of events at the conference, and pointers to coverage from others as well. Included are stories on network traffic control, the LinuxCare "Simply Supported" poster, keynotes, competing certification agencies, Zenguin, the homeless Pacific HiTech models, and more All is not perfect with Linux Expo, however. It is clear that the event is suffering somewhat from the competition from the LinuxWorld Expo.
In particular, there was a significant amount of grumbling among the vendors on the exhibit floor. Many of them did not feel that they were getting the sort of interest that they had hoped for - especially from people who might actually end up buying things. This feeling contrasts strongly with that at LinuxWorld, where the vendors were ecstatic. Unhappy vendors is a dark omen for Linux Expo; it suggests that many of them might not be back next year.
Nothing is written javatm binary kernel support for linux v103 stone, but it seems unlikely that Linux Expo will be able to recapture its former position as the primary trade show for Linux.
LinuxWorld has the funding, publicity and momentum at this point. Over the next year, LinuxWorld will bracket Linux Expo with two separate events, one on each coast.
In the future, LinuxWorld will likely be the place where people go to see the glitz, make deals, and shake hands. So where does that leave Linux Expo? The organizers of Linux Expo may want to consider adjusting their focus to take better advantage of their strengths: Linux Expo draws a higher level of technical content. Many of the talks were leading-edge and very good.
The Extreme Linux events were worth the price of admission on their own. Linux Expo is a more community-oriented event. LinuxWorld seems explicitly designed to minimize the amount of unstructured interaction between participants - it is a highly scripted event.
Linux Expo, instead, encourages informal gatherings and interactions; as such, it is a far better forum for organizing communities. Some of us also appreciated the lack of loud music, lasers, fog generators, etc. This all suggests that Linux Expo should aim at javatm binary kernel support for linux v103 the premier technical and community event for Linux.
More technical content is called for - including perhaps a stronger set of tutorials and the addition of workshop sessions. Build on the success of the Extreme Linux track with more specialized, leading-edge tracks in the future, preferably without the registration surcharge.
Finding a way to bring in development projects - which can not generally afford booth space - would be a great move. LinuxWorld may be the place you go to shake hands, make deals, and hear product pitches. Linux Expo can be where you go to find out what is really going on, participate in the process, and get your questions answered. Dan Kegel wrote in to report on performance improvements that have been in response to problems demonstrated in the Mindcraft report.
Most recently, an SMP scaling bottleneck was found, and a three-line patch was posted that quadrupled performance on one test erasing the SMP penalty. What we are seeing here, of course, is that the yelling is done, for now, and the Linux community has gotten serious about fixing the problems that do exist. This Week's LWN was brought to you by: CoolbaughManaging Editor. Security News Efforts to build a secure Linux distribution came up this week.
The basic idea is to create a new distribution which has security as its primary goal. Other details, like functionality and user friendliness, come later. Such a distribution, if it lived up to its promise, could become the distribution of choice for any of a number of security-critical applications. There are a few such projects out there, most of which are in the embryonic state.
Jon Lasser started things off with a description of a secure distribution project to be done as a project of SANS.
His thinking at this point is to start with Red Javatm binary kernel support for linux v103 distribution and tighten security from there. Alexander Kjeldaas pointed out a couple of obscure, older efforts to make a secure distribution. He also made the point that starting from a distribution like Red Hat is probably a bad idea; it is better to build a secure system from the beginning.
In any case, enough of the system will have to be different that starting from an existing javatm binary kernel support for linux v103 does not necessarily buy much in the first place. Alexander gave a list of features a secure system would need to have, relying heavily on cryptography, capabilities, and other techniques. Rik van Riel revealed that he is currently being paid to produce exactly such a distribution.
Le Reseau netwerksystemen intends to create a high-security distribution, then to make its living through service contracts with users throughout northern Europe. They are still at an early stage, having not yet decided which distribution to start with, if any. So it appears that such a distribution will exist before too long.
This update covers the sorts of activies they have been seeing recently: Red Hat has announced a new set of Netscape packages that include version 4. Some of the 4. Rather than talk about any current exploit, it gives a sizeable list of general instructions on how to javatm binary kernel support for linux v103 a web server in a secure manner. How script kiddies work.
Know your enemy III is a white paper put on by Lance Spitzner which describes just how script kiddies obtain root access on systems they are able to penetrate. Here's a set of basic security tips for Linux put out by the folks at SecurityPortal. It is intended to cover all aspects of javatm binary kernel support for linux v103 security. See the announcement for a description of the conference and the call for papers; if you wish to submit to the conference, the deadline is July 2.
Kernel development The current development kernel release remains 2. There has not, as of this writing, been a development kernel release since May There is a pre-patch for 2. Alan Cox has also put out 2. Alan had originally said that the "ac" patches were going to go away now that 2. The current stable release remains 2. There are a few reports of glitches with this version, but as a whole it has held up better than some of its predecessors.
He will be working full time on file systems and other goodies for Linux. See their press release for the details and hype. XFS promises to bring to Linux all kinds of "enterprise" capabilities that people have been asking for: If all goes as javatm binary kernel support for linux v103, Linux will have acquired something good. Thanks are due to SGI for this gift. Meanwhile, of course, work is proceeding on adding various capabilities to the ext2 file system: Now that XFS is being dropped on our doorstep, does it make sense to go forward with this work?
This question was asked on the kernel list this week, and was answered with a resounding "yes. For example, SGI has not yet said what license they will apply to the software. SGI still needs to pass through the code looking for patent and license problems; there is also the little detail of actually porting it to Linux. So it will be a while before we see any code.
And if XFS requires substantial changes in other parts of the kernel, those changes have to be done to Linus's satisfaction. Thus it has been predicted that a functioning, stable XFS in Linux is at least a year away. The ext2 work will be able to address needs far sooner javatm binary kernel support for linux v103 that.
Ext2 remains, and is likely to remain the standard Linux file system OK, it will probably be "ext3" when all the changes go inand certainly development will proceed. How to name USB devices? Development on the Universal Serial Bus drivers is reaching the point where developers are worrying about problems like: USB devices are essentially anonymous things: So how do you manage to give the devices consistent names for javatm binary kernel support for linux v103 user?
A number of ideas were passed around, including somehow using devfs for this task. But Linus shut down the conversation by saying that the problem is essentially unsolvable and that there is no point in even trying. USB devices should just be assigned whatever name is first available when they are scanned by the kernel.
It is not possible to do better than that, so there is no point in really trying. For some sorts of devices, such as mice, Linus's preferred approach is to simply have a single logical device, even in situations where there are multiple physical devices. That, he javatm binary kernel support for linux v103, will correspond best to what the user wants.
In the end if, writing kernel code in Java was the ultimate goal, one would probably decide to do it slightly differently: Writing a kernel module, which in 90 of cases is hardware related.
