Keynote: a must have information outliner, but....
by Kamaleshwar Morjal [कम लेश्व र मो रजाल] 25 Oct '07

25 Oct '07

Hi list, well i don't know if this mail is appropriate here but still, i needed help from the Linux community, so here goes: Keynote is a Tabbed notebook and personal information manager, with tree structure and strong encryption; its open source and its free. (free as in free beer as well as free as in freedom :) More info about it here: http://www.tranglos.com/free/keynote.html The only problem being its available exclusively for windows and the author states some reasons why he will not be writing one on the Linux platform. Its written in Borland Delphi and I already have the Delphi code from the website mentioned above. Also, the development of this software was ceased after version 2.0. I want to know if it is possible to convert Delphi code such that it can be compiled on Linux with the same functionality. Reason: I have loads of important documents in its native file format; so even though i found one almost similar personal information management tool for linux (a KDE project; http://basket.kde.org/ ) that i can happily use but it can't solve my problem of reading that enormous amount of encrypted data i have in native keynote file format. Besides i really liked the way keynote swiftly handles any kind of information, a really handy tool. [Please check out its website] I am willing to port that code to Linux no matter what it takes, but... i really don't know where to begin [considering i am not a professional programmer], i need help. _Any_ help here?

Re: Need Help on Linux Clustering

Hi, Thanks for looking into this. This NGO is spiritual organization. Which explain science behind spirituality. You can visit their website www.spiritualresearchfoundation.org. They can't spent money on hrdware of servers and their maintainance and it's infrastructure. So I thought it will be better if I can use commodity class systems for server with using clustering technology. On one server their will be following applications running: 1. OpenOffice 2. Tally72 3. Scribus/Pagestream There are max 50 PCs on one server. Instead of one server I want to use normal PCs approx 2-3 by doing clustering. I have heard about google. They have used normall PCs with cluster. Please tell me if you want anything else. Thanks NeeleshG LINUX is basically a simple operating system, but you have to be a genius to understand the simplicity

They have computers which are donated by people so I can't say that they will buy new 50 systems or not. Maximum client systems are i386 with Pentium 1 and 64 MB RAM.

We are running Tally7.2 Linux version on Server so noissue with that. But it eats up lot memory (Near about 50MB per instance). >group similiar hardware and describe each group in detail. >If you have wildly varying hardware, your nfsboot will be difficult to >maintain. If you want to use local resources you need 256MB ram Yes they have widely varying hardware as all PCs are donated by people. But almost 90% PCs are Pentium 1 with 64 MB RAM. And currently I am booting up them with LTSP-4.2. So no problem in thinclient system. But is it possible to get collective output of n number of PCs ? For example: If my server requirement is 3 GB RAM and 3 Ghz CPU. Then instead of bying one server of that much capacity, can I use 3 i386/586 PCs each of 1 GB RAM and 1 Ghz CPU ? Regards NeeleshG

OFFTOPIC: Unwrapping ideas at latest 'unconference'
by Frederick Noronha [फ़र ेदरिक नोर ोनया] 22 Oct '07

22 Oct '07

Nice piece contributed from Mumbai by BytesForAller Ridhi D'Cruz. --FN http://www.dnaindia.com/report.asp?newsid=1128889 Unwrapping ideas at latest 'unconference' IANS Sunday, October 21, 2007 10:07 IST MUMBAI: They call it an 'unconference', and it's a small but growing rage among techies wanting to share ideas in town. BarCamps are an international network of 'user generated conferences' that involve open, participatory workshop events. Some 200 people from diverse spheres took part in Mumbai's latest BarCamp, where content is provided by participants - often focusing on early-stage web applications, and related free software or open source technologies, social protocols, and open data formats. report continued below The BarCamp on Oct 14 was held in the IRCC Auditorium of Shailesh J. Mehta School of Management (SJSOM) at the prestigious centre for training in higher technology, IIT Powai, Mumbai. This event, christened BarCamp Mumbai 2, was the second such meet in the city. Its lead sponsor was Sun Microsystem, the giant Santa Clara, US-based vendor of computers, computer components, computer software, and IT services, known as the developer of technologies such as the Java platform and NFS, and as a key promoter of open systems in general and UNIX in particular. Sun Microsystem recently emerged as one of the leading proponents and contributors of open source software. The organisers, making their intent clear before the event itself, said that the underlying theme of a BarCamp is to turn the idea of a 'conference' on its head by removing all possible rules that hinder or limit "intense discussion". An 'unconference' is thus a collaborative discussion with no classroom rules. It is a participative session, where the speaker only leads the discussion. Participants can leave if bored or cut in when the 'speaker' is speaking to ask as many questions as they want. In July 2007, BarCamp Bangalore 4 turned out to be the biggest BarCamp so far with around 600 participants. Organiser Arpit Agarwal noticed that BarCamp Mumbai 2 was more focused on entrepreneurship than on the darling of previous BarCamps -- technology. Participation in technology-heavy sessions was low, he explained, as compared to those on entrepreneurship-related topics. This was evident when discussions led by venture capitalists (VCs) like Mahesh Murthy of the IT companies-focussed Seed Fund and start-up founders like Nikhil Kulkarni of blog-oriented Bloozle attracted visibly larger numbers. But Kunal Lagwankar's discussion on video streaming for mobile phones had many takers as well. Participants took the 'unconference-like' nature of the BarCamp to heart during his session when Lagwankar was allowed to explain his 'innovation' only after facing a quarter hour of heated questioning. Towards the end, the multimedia content delivering company Novix CEO assured all present that his team had come up with an innovation to enable mobile video quality to increase manifold. Lagwankar explained that the limited amount of bandwidth available today (30 - 35 kilobytes per second) causes a huge sacrifice in the quality of videos for mobile phones. "One of the favoured standards for video compression is H.264, an algorithm that is now available as the de facto video compressor for Apple," he said. "But this (H.264) is very complicated," Novix co-founder Lilesh Ghadi later told IANS. "Besides that, during the process of synchronization (between the device receiving the stream and the server broadcasting the stream), a lot of extra bytes get added to the stream. So the download becomes even heavier. Our innovation is a high compression algorithm that is simpler than H.264. It compresses the synchronization process. So your stream is lighter and therefore much more efficient. Now there's room for more quality," Ghadi explained, speaking from the company's Thane office. Socially oriented technologies surfaced briefly this BarCamp in Ashish Saboo's talk about building entrepreneurship among public Internet providers. He is president of the NGO Association of Public ICT Tools Access Providers (APIP) and is keen on bridging the digital divide. There was also talk about a human-powered mobile phone charger by Ankit Mehta, the managing director of Idea Forge. When asked what drove him towards this innovation, he replied that he had "felt the need for a power source in emergency situations in his personal life". "This was a huge motivation," he continued. "When you look at the bigger picture," he emphasised, "there is a huge need for such a charger because of acute power shortages in rural and semi-urban areas." With the expansion of mobile usage and networks across the country, Ankit believes his product will fulfil a growing need. Priced at Rs.200, the product called 'e-charger' will hit the market in a few months. BarCamp claims to have a history of product launches and this event saw two. One was a new feature of randomly navigating through recommended Short Messaging Service (SMS) forwards available online on Rahul Gupta's vakow.com. The other is a peer-reviewed blog and news content aggregator called Bloozle. Interestingly, the trend of collaboration and sharing seen emerging since the introduction of Web 2.0 technologies like blogs and wikis seemed to be driving this 'unconference' even in the nature of innovations launched. Some participants later felt that running four parallel sessions made it inconvenient for some, especially since the four venues were far apart. The term 'BarCamp' was first coined when a couple of geeks revolted against not being invited to open source publishing luminary Tim O'Reilly's annual invitation-only participant driven conference Foocamp. The first BarCamp was held in Palo Alto, California, in August 2005 and didn't take much time to reach India. -- Frederick Noronha http://fn.goa-india.org Ph 0091-832-2409490 11866 downloadable, sharable hi-res photos http://www.flickr.com/photos/fn-goa
