[Ilugc] Ubuntu vs. CentOS vs. Fedora for my new server ?
Hi all, Important: This can easily become a flame war - request all to please avoid making this personal and keep this limited to the distros instead of the distro users. (Hate the sin not the sinner.) :-) Am setting up a new public server. This will have our default website as well as all tools to help our developers develop from across the globe.Will host website, proj mgmt (redmine), subversion, jenkins, Selenium automated test, build tools etc. This will be either on digitalocean or AWS. I have not been a linux admin for about 3-4 yrs now and have not really kept up to date on the developments. At that time I was managing Fedora/CentOS and I am comfortable with its internals. Very comfortable with rpm, service and init processes, file system layout etc. At that time Ubuntu was fast catching up as a great alternative to Fedora/CentOS on the serverbut did not follow it after 2010. I did use Ubuntu exclusive as my default desktop OS for almost 6-7 yrs but never really had to use command line there and hence I am familiar with (but not an expert) with 'Ubuntu' specific stuff like upstart and the placement of config files in filesystem etc. Ubuntu on Desktop was a dream - it just worked with all the hardware without me having to compile any drivers. I want to manage this server with minimal compiles but want latest versions of tools and libraries (RoR, php, Java). My current "old" server is CentOS 5 which I initially booted up in 2008. I really need to upgrade :-) For my new server, which would you recommend between Ubuntu, Fedora and CentOS ? Please do not make this a flame war. I know they are great distros - I am trying to see if it is worth learning Ubuntu server side stuff or go with Fedora/CentOS where I am already comfortable. Thanks,kc -- K. C.

[Ilugc] Dell Vostro 1510 Keyboard and Touchpad (Arun Venkataswamy)
Hi, We have 2 Dell Vostro 1510 (bought a few weeks back) running Ubuntu. Everything works out of the box except wifi for which I was too lazy to configure ndiswrapper. I have configured wifi with ndiswrapper in quite a few machines and it works perfectly. Based on your description "noapm, noapic and noacpi" it looks like you have an AMD64 processor. Intel does not need those options. Try Ubuntu (either live or install) - it should support all hardware without trouble (except wifi). I shifted from Suse to Ubuntu. Suse seems a lot slower on the same hardware. I was born & brought up on fedora but fedora needs more tinkering to get it working correctly on laptops especially wifi and multimedia. Tried Suse for a few months. Seemed *very* sluggish. Ubuntu's restricted drivers makes it really easy for laptops/desktops. kcK. C.

[Ilugc] Re: This is T.Arulalan, doing M.C.A in Saveetha Engg College
Hi Arulalan, TCP/IP is the underlying architecture of the whole Internet. The power of these protocols is surpassed only by their simplicity and elegance. I have worked on various Internet protocols for Lucent and Conexant and I think TCP/IP are the most elegant, simple and powerful protocols of them all. I am based in Hyd and hence cannot give a one day seminar but the right way to understand the protocols is to read the RFCs. At first the RFCs may seem a bit dry/complicated but once you read a couple, you will start enjoying them and appreciate the precise language used as well as the thought process. TCP/IP includes UDP/ICMP too. For a more complete understanding, you will need to understand at least one routing protocol like RIP and also how DNS works. Some resources/books are also listed below. You will find the RFCs on http://www.rfc-editor.org/ Here is the RFC for IP: http://www.rfc-editor.org/rfc/std/std5.txt Here is the RFC for TCP: http://www.rfc-editor.org/rfc/rfc793.txt Other RFCs: ICMP: http://www.rfc-editor.org/rfc/rfc792.txt UDP: http://www.rfc-editor.org/rfc/rfc768.txt Books: (Only if the RFCs seem too complicated. I rememeber the authors - not the exact title of books) 1. TCP/IP programming by Doughlas and Comer (3 parts when I read them in 1998 - don't know about now.) 2. Networking by Tannebaum. (This book tends to be a bit confusing. Don't focus too much on the OSI model - just read the TCP/IP parts.) If it all seems too confusing, just take a deep breath, close the books and focus that we are just simply trying to achieve transfer of data from one comp to another without loss. Try and imagine your own solution for it and then compare your model with the mechanism described in the RFC - you will understand the RFCs faster. You can master the RFCs mentioned above if you spend 3-4 hrs a day - it will take 3-5 weeks including re-reads, confusions, clarifications For code samples, you can see the Linux kernel but that is of course very advanced at this stage :-) You can mail me if you have queries of course. I have had a lot of fun reading and understanding these protocols and am totally awed by Jon Postel, Vincent Cerf, and other assorted authors and how they could plan so much in advance. I hope you derive as much joy as I did. Congratulations on having started on something very wonderous and believe me, if you manage to really understand how these protocols work, you will have an excellent understanding of the Internet, joy in life in addition to high paying jobs waiting for you :-) kc K.

Hi, There are 2 solutions apart from iptables: 1. Hardware solution: Buy a hub (~ Rs. 600 for 8 port I think - dont remember exactly but very cheap) and connect both machines to this. You will have to set them to DHCP and they will get LAN IPs from hub. This way you can add more machines and also will not have issues with any protocol. You can also buy a wireless router which you can plug either to your BSNL modem or the (new) hub - that will give you wireless internet. I have BSNL in my house and they have given me a wireless router - we use 2 laptops(wifi) and a desktop(Lan cable) in our house. 2. Software solution: Run squid on CentOS. It is a fairly easy install and will also provide caching - this will improve your browsing experience. If you are able to ping the Internet from CentOS, just load and configure squid (~1-2 steps) and configure the proxy in your Ubuntu. Squid will also help in terms of content filtering, access control, log of sites visited. Squid will not help with ftp - there used to be a ftp-proxy sometime back. You might have to configure ftp in iptables - which is again a pain. Let me know if you run into issues.

[Ilugc] Re: Help needed - recovering formatted ext3 (Ravi Kumar Tenneti)
> Please try http://www.cgsecurity.org/wiki/TestDisk > and post the details. Thank you. I did download Testdisk but was not sure whether I should use it. I did use it after you recommended it and it worked like a charm. Its absolutely fantastic. It showed me all previously deleted partitions, the folders and files. It offered to copy them and as I am typing this, it is copying files from the depeted partition to my external harddisk. It must have saved me at least Rs. 5k in charges and a lot of headache. I can't praise this software enough. Mohan suggested Photorec. It is a part of Testdisk download package. I havn't tried it out but will do it today. For referrence, I will explain how the backups/restore failed -- this should prevent others from making the same mistake. 1. I use the tool 'Simple Backup and restore' in Ubuntu. 2. I had configured it to store the backup files into an external hard drive. 3. I took a backup (almost a year back) and tested it by restoring from the backup and everything worked fine. 4. I have been backing up regularly at least once a fortnight. I look at the processes to verify and have noticed that the tar and gz processes run as expected. 4. I also took a backup just before formatting. 5. After formatting, when I tried recovering, I realised that the last backup in the hard drive was about 3-4 months back. So what happened to all the backup files I think I solved the mystery ..Read on to know. 1. My external drive is named "KC" and when mounted is accessible via "/media/KC" 1.1 I configured 'Simple Backup and restore' to backup to "/media/KC". 2. About 3-4 months, back, I clicked on backup without noticing that my external drive was not attached. 2.1 Half way thorough the backup, I realised it, aborted the backup, attached the external drive and started the backup again. 3. The 'Simple Backup and restore' tool did a very stupid thing. When the external drive was not attached, it went ahead an created a directory called "KC" in "/media". 4. So, when I attached the external drive, Ubuntu mounted it to "/media/_KC" - notice the underscore in "_KC". 5. Since 'Simple Backup and restore' was configured to use "/media/KC", it happily backed up everything to my laptop harddrive and not my external drive. 6. When I formatted my harddrive, I lost all backups in "/media/KC". 7. I should have done a simple copy/paste of the important folders from hard disk to external drive but my supreme stupidity made me decide against it and I paid the price. Please be very careful when taking backups and do try a restore at least once a month. These kind of stupid problems can be easily detected and corrected by doing a test restore to a different PC or distro every month or so. I had Fedora on a separate partition. If I had tried a restore in Fedora, I would have found this error during the restore. (Don't try on the same machine/partition as it will restore perfectly.) Hope people learn from my mistakes and don't have to face the sinking feeling when I realised that I lost almost 3-4 months of very valuable data. Thanks again to Ravi and Mohan. There are a couple of other tools too but will try very hard not to be in another situation where I have to recover from formatted hard drive. Regards, kc K. C.

[Ilugc] Re: Recovery with testdisk
Updates: While trying to recover, I had another idea, if you remember, I theorised that "Simple backup and restore" created a directory in /media. Following up on that theory, I used testdisk to go to /media/KC in the old partition of my laptop harddisk and lo behold, the directory did exist and all my backups (almost 15 of them - I am a paranoid backer upper) were safely in that directory. !!! WIN !!! I recovered all my incremental backup files. I had my original full backup and hence have all my data back. BTW, Ubuntu puts the underscore *after* the name. Since /media/KC" was created by "Simple backup", Ubuntu created the directory "/media/KC_" and not "/media/_KC" (i.e. the underscore is *after* "KC" and not before) as I wrongly reported in my earlier email. Moral of the story: 1. Take regular backups on external media like DVDs and keep testing restores once a month or so. 2. Keep thanking the selfless souls who write great software and release it under GPL 3. Make contributions to projects which save your life - either code, bug reports, testing, documentation or cash (I am donating $$ to testdisk!!) With this exercise, I have become pretty experienced in data recovery - I recovered a mysql DB after a bug dropped all tables in the DB in the production server. It was a new server and we still hadn't started automated backups on it. It is possible to recover the DB from just the ibdata files provided you have the schema and have some idea of the text content of the tables. I would also recommend Jaunty - Ubuntu 9.04 to all. It really is very good. Though I have been a lifelong RH/Fedora fan and use Fedora/CentOs on servers as well as my laptop, I started dual booting (actually quadraple booting - Fedora, Ubuntu, Suse and ...) Ubuntu since 7.10. With 9.04 I think I have migrated completely to Ubuntu on my laptop. I erased Fedora 10. I am very used to Fedora/Cent on servers mainly because I have been using it since 1999 and know it well - .profiles, .rc, service controls, init.d.but for everyday office use - documents, scans, productivity...Ubuntu is really up there. In terms of usability for non-geeks, I think Ubuntu has finally beaten Windows. The usability is fantastic and desktop effects work without binary drivers. It is very close to Mac and should beat it too pretty soon. Thanks to all for reading my lng emails and for pitching in with suggestions. kc K. C.

[Ilugc] Re: Configuring squid to block the systems on a network
I searched to see if I have any old acl lists but couldn't find them. I did this a long time back but remember enough to give you a start. For the actual syntax, there are a *lot* of articles on the net. 1. You will have to define groups of computers(IP addresses) or users(people). 1.1 Lets look at IP addresses: 1.1.1 You can have lists of individual IP addresses: Eg. developers=192.168.0.2, 192.168.0.4, 192.168.0.5, .. test_engineers=192.168.0.3, 192.168.0.6, .. 1.1.2 You can have a group defined as a net mask: developers=192.168.0.0/255 test_engineers=192.168.1.0/255 2. You can create groups of URLs, whitelists and blacklists Eg: blacklist1=*facebook.com, *myspace.com, *exe blacklist2=*flickr.com, *picasa*, *zip whitelist1=sourceforge.net, rubyforge.net whitelist2=google.com, rediff.com You can have these as external text files. Also accepts regex You can restrict downloads too using this process - notice the *exe above. A group can consist of single IP too. A single IP can be in multiple groups but try to avoid that as it leads to confusion on what is allowed and what is denied. 3. Finally define which group can access which list. (acl = access control list) 3.1 For a tightly restrictive system, first DENY everything to everybody and then allow access to individual whitelistslists/sites to individual groups. 3.2 For loose system, ALLOW everything to everybody and then DENY individual balcklists/sites to individual groups. 3.3 Make sure that you set relatively loose permissions to CEO and top mgmt. 4 MOST IMPORTANT: Make sure you communicate well with all people in the firm. 4.1 First send out an email that you are introducing usage policies and that they will be some teething problems and that they will be streamlined over time. Tell your users that they may initially face issues in accessing regular sites too as the rules are not fully tested. Ask them to send emails with requests - this will reduce a lot of friction during the initial phases and you will also have a list so that you will not forget. 4.2 Start with a small group, stabilise it, then move on to bigger groups - do not try a big bang approach. You will face a lot of problems with a big-bang approach. 4.3 Finally remember that you are trying to reduce wastage and bandwidth usage to enhance productivity - be responsive to allowing productivity sites like technical help...be proactive about helping them be more productive. 5. You can also ask squid to use your Directory Server so that you monitor based on user rather than IP address. That is slightly advanced and you can try it later. Thanks, kc K. C.

[Ilugc] FOSS app released
Hi all, We have released a Free application on rubyforge quite sometime back. In addition to the source code, we are planning to host it for free for the Free Software Community. The tool is basically a filtering mechanism of community ideas based on 'widsom of the crowds'. 1. Any registered user can create an idea. 2. Other registered users can 'vote up'/'vote down' the idea. A single user can cast multiple cotes to a single idea. 3. Users have a 'vote account'. When a user casts a vote, this account is depleted accordingly - so use your votes wisely. The account balance is increased when a new idea is created in the system. 4. Every idea is 'retired' after 3 months and prizes are announced based on its performance. 5. We are also planning to introduce cash prizes within a month. Prizes will be awarded to both the idea creator as well as the users who have voted for the idea. There is a logistical issue with this currently and we will be paying only to paypal accounts. If you do not have a paypal account, the amount will be either donated to FSF or to a free software project of your choice which accepts paypal. We can look at other modes of payment in the future. I will be releasing the documentation including installation instructions over the coming week. Meanwhile please log in and start using the site - who knows - your idea may win cash prizes. http://rknowsys.com/ideaxchange/ The application will get its own URL within a week and will be migrated without data loss. The source code link is available at the bottom of the home page in the app. I would like to introduce it to all lugs and once the application is stable, a more plublic launch is planned. Please forward this link to other lugs and other Free software enthusiasts. Of course contributions (code, bug reports, documentation) are welcome. Thanks, kc K. C.

To my surprise, I found them not available. These are not common names - they are very specific to a niche service and I doubted that somebody else would have thought the of same names at the exact same time. On googling, I found that Network solutions and some other registrars do something called 'front-running' where they basically block all domain names that were searched for and force you to pay more.

You need not have a fancy office in the beginning. Always have cash equivalent to 2-3 months of expenses in the bank. 2. Get good people to work with. 3. Keep thinking on how you can give more value for money to the client. This is for throughout your career. 4. Personally recommend having at least a few years of work ex as most business will be vary of trying out freshers for business critical stuff. Also recommend reading up basics of mkting, strategy. Remember that 99% of startups fail - plan around this. 5. You can be in a niche area and charge premium or get into LAMP kind of stuff which is low billing but high volume. 6.

[Ilugc] More on freshers planning a startup
Hi all, One word of caution. I would recommend people sticking to facts rather than anecdotes. The golden image of college dropouts starting successful companies if the exception and not the rule. For every successful college dropout, there will be 200 failures. Do not compare yourselves to Bill Gates, Steve jobs, Dell etc. Bill Gates was from a VERY wealthy family with a LOT of connections. Steve Jobs had a team of experienced people from Xerox and stuff, Dell was running the business for some time as a student before he quit. Also US has way more opportunities in terms of funding and entrepreneur support. I would like to remind Karthik that these are really young and impressionable people and I would advise caution. I have built a sustainable business based on FOSS consulting. Been through a lot of ups and downs. Starting up sounds sexy but there is a lot of risk - it takes talent, a lot of hard work, adaptability, a very strong heart and most importantly dollops of luck. Yes. Luck plays a pretty important part. Also the potential entrepreneurs should understand the there will be a lot of advise on this forum but if your business fails, at the end of the day, you have to feed yourself and pay your own bills. If you try to go back to a job, it will be tougher both for you and potential employers. You will not have any hard skills and for the other skills, prospective employers will be under the impression that you will quit as soon as you have the next great idea. The thrill of entrepreneurship is that bottom-line responsibility rests with you and that exactly is the risk too. Be aware that you are risking your life. Better do it with more preparation. >> And maturity counts in biz more than anything else. >> >> Also working for companies will tell you what it takes to do biz. > This is a myth. The history of startups shows us that the best > entrepreneurs were neither mature nor experienced when they started out > If anything, the history of college-dropout entrepreneurs shows us that > understanding a specific customer need and build a kickass product to > address it is the best way to build a startup.

[Ilugc] Re: any one can tell which is better php vs java or ruby on rails ?
This is going to be so much fun !!! 1. The comparison itself is not really fair. php and Java are languages while RoR is a language+framework combo. The correct comparison will be php vs. Java vs. Ruby. My order of preference here is 1st Ruby, then Java and then php. 2. php and Java have MVC frameworks too which compete with Rails. php has 'Symfony' and Java has 'Struts'. Hence you can have Rails vs. symfony vs. struts. 3. The nitty-gritty 3.a. php + symfony - good to excellent for small projects. php started as a procedural language and is not fully OO. Hence, code gets increasingly difficult to maintain as proj size grows. But php is easier to learn, very mature libraries, lots of php developers and in general easier, cheaper both for development and maintenance. Yahoo front end is pretty much entirely php. I think the total amount of PHP code available on the net is 2nd only to 'C'. I personally detest php due to the inline html part. Also the language/syntax is not 'elegant'. php is also aged - parallel will be that php took up a lot of space where initially PERL was used. Similarly, ROR is eating into php territory. 3.b. RoR - my personal favourite. excellent for upto medium-large sized projs. Absolutely a programmers delight. Ruby is fully OO. Rails is excellent MVC and the ORM is great. By 2009, even the libraries and plugins sorta caught up with php - rubyforge.com High productivity - much higher than php due to the native methods of Ruby. i.e. You do not have to write code for sorting, searching, ordering etc in ruby - just use the inbuilt stuff unless you are Knuth's Ekalavya and know a 'better' optimisation. Same for Rails. The framework does so much that you just concentrate on the business logic rather than algorithms and n vs. n^2 vs. log(n). jquery is the only major library not fully integrated with ROR but that should be integrated in 1-2 months with the release with Rails 3.0 RoR is perfect for almost 90%-95% of web apps where CRUD is the main concern. For the remaining projects that don't require MVC, do NOT go for RoR. The number of RoR programmers are lesser and hence more expensive. Shared hosting of RoR is not as popular as php. 3.c. Java/Struts - This is for 'industrial strength' projects. Java has a lot of good stuff going for it but I really don't think you can compare Java/Struts with RoR/symfony - they are aimed at different categories of applications altogether. Java is more resource hungry. Java is a bit of a pain to develop and test due to the building+deploying latency and unless you need Application Server features, you really don't need Java/Struts. Java also requires more effort to deploy and maintain. Have a good look at what your planning to do and then take a decision based on your comfort zone. cheers, kc K. C.

Now this is an interesting problem. It does not seem logical that a Win virus
can cause this. There are a couple of possibilities -
1. The virus is at a lower level than 'autorun' - extremely unlikely.
2. My guess is that the drive itself is faulty - not easy to verify.
3. Something else which I can't begin to understand.
Try googling to see how you can 'reset' flash drives. We could wave strong
magnets over previous generation of hard disks - is there something equivalent
for flash drives?
Thanks,

[Ilugc] Re: Re: How to protect an idea from getting patented by
> Seems like if you want to do software business in united states, you > have to commit the sin. We are a free software consulting firm. I am a paying member of the FSF. I subscribe to the patent related views of FSF. I also subscribe to the 'pragmatic idealism' view point. Morality and Legality are very different. We need to operate within the established laws. As the laws are bad, FSF and other organisations are lobbying to change them. Until they are changed, we need to adopt a practical approach within the boundaries of the law. Best thing is to patent it and then transfer ownership to FSF. We applied for a patent which was rejected. But if we had been awarded it, we were planning to assign ownership to either the FSF or http://www.openinventionnetwork.com/ The other solution is to challenge the patents legally by citing prior-art. I am not commenting on the morality of patenting here but the practical solution in the real world scenario where patent laws exist. Until software patent system are legally dealt with, the above solution is the most practical. Patenting costs quite a bit of money so be warned. Regards, kc K. C.

[Ilugc] Re: Linux compatible printer (Arun Khan)
> The OP is querying specific brand/model that are *known* to work from > Linux user experience. I recently did quite some research and ended up buying samsung CLP 300 series - specifically Samsung CLP 315. This is a pure printer i.e. no scanning/fax/telephone. Most Samsung devices have Linux drivers and are downloadable from their site - samsung.com/in I also researched other printers - HP, Canon, Brother...but Samsung is a pretty strong brand with a clear Linux driver policy and I just went with it. My only regret is that I did not buy the wifi enabled model :-) kc K. C. Ramakrishna www.rknowsys.com ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
[Ilugc] Kalculate, Tally, GNUCash
Hi all, I wanted to maintain accounts of our small FOSS firm. Currently the accounts are being maintained by an external accountant in Tally. I want to start maintaining them in-house (hopefully myself) and in my research I found Kalculate as a promising alternative. But looks like you are better off with GNUCash. Here are my reservations on Kalculate: 1. It is not Free software in any sense. There is no 'community edition' either. Just an evaluation edition. 2. The last release of Kalculate seemed to be in 2006 - http://openlx.com/download.php 3. I do not seem to be able to download from here: http://kalculate.com/download.php 4. Don't know if it is keeping up with changes in accounting standards. Looks like the co. is dormany/hibernating. I sent them and email - lets see if they respond. 5. The only connection with Free Software is that it runs on Linux and they have some OpenLX distro but Kalculate itself is NOT under and 'Free' license - GPL/Apache/MIT I am currently trying out GNUCash. This should be interesting - I do not really know the difference between voucher and invoice. If anyone is planning a GPL alternative to Tally (accounting ONLY and not ERP), please talk to me. I should be able to provide support. kc -- K. C. Ramakrishna www.rknowsys.com ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
[Ilugc] Updates Re: Kalculate, Tally, GNUCash
Hi all, Am posting this on both ilugc and ilughyd. ___ > 2a. Re: Kalculate, Tally, GNUCash > http://bitbucket.org/lawgon/avsapdjango > 1. Gave up on Kalculate - no response from the co. and no community edition either. Will strongly urge them to GPL it. 2. Not trying to run Tally on Ubuntu. Also Tally has expanded to include ERP functionalities and cannot figure out from their site how to buy just the accounting part. Will continue with external accountant if forced to use Tally. 3. GNUCash is on standby as its more tuned for US accounting. I would prefer an India specific package. Will support one of the evolving ones till its ready for use. I looked at the 'avsap' link above but will appreciate feedback from actual users. are there people using this software? Also updates to this seem to be sporadic. KG generously offered a login to test it but I am yet to take him up on it. Am not an accountant - what will I test? :-) I also looked at GNUKhata. This seems to be under more active development and am getting email digests from their user lists. GNUKhata seems relatively more mature. Installation seems fairly simple on Ubuntu 9.04. One issue is that they do not seem to have tested with an empty Database. I had a few crashes when I was adding master data. I have not proceeded to adding transactions yet. At this point I am partial to GNUKhata. Will update afer I check out avsap. I am looking at India specific accounting software as hopefully these will be more in tune with Indian accounting and taxation practices. I also hope that as these softwares mature, they will automatically calculate tax, depreciation etc :-) I just want to enter data and click buttons for everything else :-) I have to buy a book to learn accounting I guess (sigh!!! the travails of entrepreneurship) Cheers, kc ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
[Ilugc] Query: Tools for monitoring servers
Hi all, We are trying to look into monitoring servers in Beta and Prod environments. The stack: a. 2(more in future) Front End apache httpd/tomcat/Liferay Servers b. Independent CAS-SSO and SOLR servers. c. standalone server running webservices (written in Java) d. 2MySQL (Percona) servers 1 WRITE server and both READ. e. Front end Hardware Load Balancers. We want to monitor continuously: a. All the Linux boxes and the services running on them, b. The performance (and history) of the Java applications too. We are exploring the best ways to monitor the whole setup including alerts and automated restarts etc. We are primarily from a development background with only basic admin experience (basic bash, installations, tuning etc). I have researched all the usual suspects: Cacti, Nagios, ZenOSS, Zabix?.. JMX seems to be very popular for tomcat/Java. What are your recommendations for handling this scenario? What are the pros and cons of various tools and approaches? Please do share your thoughts on what will be a good solution. All live examples will be very welcome in educating us. Thanks, kc -- K. C.

[Ilugc] [OT] Challenging Aadhar (UUID)
Hi all, Slightly off topic depending on how we perceive this. Posting this here as I assume most Free Software people will be opposed to surveillance as a matter of principle. I am sure most people on this forum are familiar with Dr. Stallman's views on surveillance, facebook and mobile phones. Though the stated objectives of Aadhar is improving govt. delivery efficiency and fighting corruption, in reality it is also enabling a massive surveillance structure over all Indian residents. I think there some free software / open source components to the Aadhar project and in my opinion that is an irony. Mr. Matthew Thomas and his team have started a legal battle against Aadhar. They are using RTI and courts to unravel the facts and publicise the truth. Apart from my other contributions, I am trying to do my bit in trying to raise support for it. You may find more here: http://www.thefifthestateworld.com/ Here is a gist of Mr. Thomas's appeal in his own words: >"What we need is people to analyse the UID scheme and take appropriate decisions. They should not be carried away by the media image or political affiliations of the prime-movers of the >project. >People who understand the dangers of UID could contribute by taking the message through any media they have an opportunity to bring out the truth. >I request you to email, suggesting to the community to register on the website, post articles, news, blogs, mails to MPs, CMs, post comments on news, like the one on 'IBN Live' today. >They could promote the website. >Please post your comments on the lies he is saying. He said that the trials for LPG delivery is successful. Reply to my RTI query on this is that the trial is NOT complete. >I have two Google groups, one called 'Citizens Action Forum' and the other called, 'UID - India's Orwell'. They could register on these groups and post there too. " If you care about this cause, please register on the sites and the forums. If you think other lugs across India will be interested, please do spread the word on those forums too. Thanks and Best Regards kc -- K. C.
