which method is more efficient to implement for any file editor?
by sachin puri 09 Mar '09

09 Mar '09

Hi I am sachin Puri I am new linux user. I have following observation in case of vim editor and have some question regarding it so whole scenario is like given below . What I have done and observe Case 1 - I set all permissions (rwx) for owner on parent directory. (I am the owner.) $ ls -ld dir drwxrwxrwx 2 sachin sachin 4096 Mar 7 13:42 dir and has structhure like below /home/sachin/dir/text.text In this case when editing the file "text.text", vim creates a temporary swap file in that directory. When the file is saved, the swap file is deleted and the inode number of "text.text" changes (it is different from the inode number of the original file and also the swap file). Case 2 - Write permission is removed from parent directory $ ls -ld dir dr-xr-xr-x 2 sachin sachin 4096 Mar 7 13:42 dir In this case when editing the file "text.text", vim creates a temporary swap file in /var/tmp. After saving the file, its inode does not change. This means that in case 2, vim is updating the contents of the file in-place. I have found that OpenOffice.org also updates the contents in-place, irrespective of the parent directory permissions. I wish to know why does vim create a new file in case 1. Wouldn't it be a costly operation, especially in case of large files? In short, which method is more efficient to implement for any file editor? Please note that in all cases, all permissions are set on the file itself (i.e. text.text). I am just manipulating the permissions of the parent directory. thanks in advance

Installed Lenny on Acer Aspire One
by Rony Bill 06 Mar '09

06 Mar '09

Hello, I installed Debian Lenny on the Acer Aspire One.Lenny is ideally suited for netbooks as it has a lighter foot print with good looks. A week ago I had already installed Lenny on my pen drive for testing. Lenny DVD has a superb boot menu that lets you choose your desktop without having to remember the exact syntax. (A minor error in the older method meant that instead of KDE, you end up with Gnome. I had selected KDE. Those who do not like KDE4.1 will love this older KDE. Lenny comes in a down to earth build yet good hardware support. Everything worked fine except wireless and thats where this site comes in handy. I used the mad-wifi drivers using the apptitude method given in the link. That is the fastest. http://wiki.debian.org/DebianAcerOne#head-0c033e1a554405a43cc9a4043e5f6c9d9… After that the system was restarted and Knetworkmanager was able to get me online. Gnome users please read about network-manager not working and instead the use of wicd. Otherwise everything isthe same as setting up Kubuntu in Acer Aspire One. -- Regards, Rony.

Netbooks may rob you of privacy
by Rony Bill 06 Mar '09

06 Mar '09

Dear Sir, With reference to your article in HT on netbook security. The first impression one gets from it is that it is aimed at hitting the netbook sales. If the authors really had a proper understanding of operating systems and security issues related to them they would have never posted such an article. Neither the bigger notebooks nor the smaller netbooks come pre-installed with any firewalls or anti-virus software. The anti-virus that is pre-installed on some notebooks that have an operating system pre-installed is only a trial version which will expire anyway. Antivirus software slows down any system and the problem is not limited to netbooks only. By the way the netbook has a 1.6 GHz. processor and a 1 GB RAM and a 100+ GB hard disk, which is quite sufficient for a normal anti-virus software. I happen to use one with an anti-virus installed. What about the expensive business cell phones that are fully net enabled and are used to surf the web, check mails, blog and chat? Is there any scope for putting any of the standard antivirus software in them? The most important point missed out by the authors is that security issues arise from faulty operating systems that are breeding grounds for software viruses. Since these operating systems are closed and do not allow any security audit of their program code by outsiders, there is no way one can know their inherent flaws and predict as well as prevent future security problems. In order to overcome this limitation of closed code software, there are Free(dom) software operating systems that are openly audited by experts outside the core developer group and the general public. This enhances the immunity level of these operating systems to such an extent that they do not require any antivirus software. They come preloaded with security measures in various stages that prevent virus files from executing in the system or propagating to other computers on the network. The good news is that these Free(dom) operating systems can now be installed on the netbooks too and users can make full utilisation of the hardware resources for their own work. I sincerely hope HT will let its readers know more about these secure Free(dom) operating systems like Debian, Kubuntu, Ubuntu, Fedora, Mandriva etc. -- Regards, Rony.

[OT] Dear Admins
by Dinesh Joshi 06 Mar '09

06 Mar '09

Hello all, Remember me? If you're an admin you must be wondering how in the world did this guy get off moderation? It was simple. I was waiting and watching if some sense prevailed on your part but unfortunately not. Anyway, this email isn't to insult anybody. It is a polite reminder that please do not mess around just because you have been given the power here. It can be just as easily be taken away / circumvented :) I was unjustly shut up on this list for having my opinions. Some stranger insulted me and I stood up for myself. Thats all I did. I was referenced in several threads and I merely replied to them and I'm shut up which is incredibly stupid and has encroached on my rights as an individual. This is an open forum and you cannot shut me up. It is a violation of my freedom of speech and expression. If you shut me up then you have to shut everyone else up who referenced me. Other people too were involved in blatant name calling and acted as proxies. That was a low, unprofessional thing to do. I did not see any action being taken against them. I believe you've misused your power as admins or you've used them in ignorance which is pretty much the same thing. None of you actually followed the threads that I was attacked in or know what really happened. Mr.Dinesh Shah / linuxer-owners did not respond to my emails and no amount of reasoning showed you guys the irrationality of your decisions. I have been and admin & moderator on several forums. I've been in such situations. The reasonable thing to do is warn all members and put *all* of them on moderation. Singling one out of the many is wrong. If anybody should've been punished, it was the person who provoked the whole flame war. Lastly, to all who are / were / will be in a position of authority. Please DONT let that go to your head because your power is *not* absolute :) Kind regards, Dinesh A. Joshi

FYI VIVEK Kundra : CIO in US
by jitendra 06 Mar '09

Kundra on Open Source ( http://radar.oreilly.com/2009/03/vivek-kundra-federal-cio-in-hi.html ) *VK:* I think you look at open source, as a technology, whether it's mediawiki, for example... with Wikipedia what we did in the District of Columbia was that we had a wikipedia solution that allowed every single employee to collaborate and have access to information. * I think there is also a place for specialized software, you look at the FAA or if you are looking at DHS, there are some mission critical systems that you can't apply an open source solution to.* We need to have a very pragmatic, balanced approach in terms of software. I would argue that, whether it is open source or proprietary software one of the biggest ticket items when it comes to information technology on that $71 billion dollars is the money the federal government spends on contracts and contracts that, frankly, some of them haven't performed very well and there have not been consequences. And, we need to become serious and tough on those contractors that are not going to deliver. Eliminating those contracts and making sure that we have consultants and contractors that are adding value to the federal government. -- jitendra

Software Patents
by jtd 06 Mar '09

06 Mar '09

Ref TOM TOM v/s M$. http://www.groklaw.net/article.php?story=20090305203031867 This one affects everybody using FAT / LFN and will expand to affect everyone using ANY M$ file system. What is the story on the Indian Patent office's take on software patents. After all the noise they seem to be ominously silent. Did anyone attend CII –DIPP Nationwide Intellectual Property Rights -Awareness Campaign held on 3rd March in Mumbai. Btw my email to M. W. Dhumane dated 26/8/08 specifically pointing out some software patents (217179, 210794, 217913, 220214) issued by IPO has received no response. The letter also specifically asked them about the procedures they used to identify obviousness and prior art. -- Rgds JTD

Trai guidelines
by Information Security 06 Mar '09

06 Mar '09

The following are the guidelines to be followed by the ISPs as per trai on urgent basis: - 1. Provide adequate information to subscribers regarding Internet/broadband services being offered and marketed as a good business practice. 2. Provide information regarding contention ratios (number of users competing for the same bandwidth) adopted for different services by service providers in their tariff plans submitted to TRAI, manual of practice, call centers and on their websites." 3. Publish contention ratio for different Internet/broadband services on their website quarterly to facilitate subscribers to take informed decision. 4. Ensure availability of minimum required bandwidth in their network according to maximum contention ratio suggested by TRAI for different services based on number of subscribers. Since guidelines are recommendations, and in this case, it means there aren't any deadlines to meet by the ISPs to start adhering to these guidelines. Moreover, it is mentioned in the guidelines issuance notification that "any regulatory burden in present economic environment of Internet sector may increase the cost of service provisioning and will adversely impact the growth of broadband. The Authority prefers least regulatory intervention while providing greater flexibility to service providers to ensure better quality of service to internet/broadband subscribers." Therefore, subscribers cannot expect ISPs to be in a hurry to enlighten subscribers with the nitty-gritty of why they cannot be assured better broadband services.

High Resolution video conferencing.
by Rony 04 Mar '09

04 Mar '09

Hello, There is an advt. of CISCO where a group of people from China and Some European country come face to face virtually on huge screens. Is this really possible or just trick photography? If possible, it would not only help in overseas conferencing but also in huge office complexes where one has to travel a long distance or even a few floors to get to the boss's cabin or some place else. The normal video conferencing has a very small screen where one cannot even move one's head or it would get out of the visible area. With high resolution videos, a huge life size image is possible and groups of people can talk to each other. It has a fantastic effect and looks really good. Keeping aside the cost and availability of net bandwidth, is this possible with Linux. If it is not very expensive, could we actually setup a prototype in HBCSE during our forthcoming GLUG meets over the months? A LAN cable should provide good bandwidth for intraoffice video conferencing. We can link up two classrooms or the lab and classroom. We already have a projector and a 17/19" LCD screen. I am sure this has good commercial potential too for big corporate offices. -- Regards, Rony. GNU/Linux ! No Viruses No Spyware Only Freedom.
