Nokia N900 – Definitely Geek

At last, Finally Nokia decided to come out from Symbian shell, at last we are talking about something that would be really Open Source and could be customizable, at last we are talking about a device that would be all; Top of the Internet Tablet with Flash 9 enabled full fledged browsing, Modem/ Wi Fi spot for your computer, Music player, Video player with resolution of 800x 480, Decent Camera (5MP) for still and video recording, Ebook Reader (PDF till now, but Doc viewer could be added soon.)

Earlier here in India, we heard a tagline for Bajaj Pulsor bikes, where they said “Definitely Male” for the killer look and feel the bike possessed. A superbike look with best of the features with affordable price for medium class suddenly changed the whole scenario and sure the tagline always stood tall and true.


Nokia bringing back the similar effect with path breaking Nokia N900 and itsmaemo-raised-the-bar new Open Source counterpart ‘Maemo’. Definitely Geek!!! were the first words in my mind after experiencing the test unit that arrived to me two days back. As I am learning about its features and capabilities, its fascinating me more and more. It stands in its own league and I really want to see till how much time techies will consider The Eye Candy iPhone (packed with all propriety things) something worthy to talk about.

Writing about something is tough, when already much has been written about. I have already read some excellent articles about its features and possibilities and by every hour more are being added, when as of now, its not released in all parts of world (not released in India, if I know right). Its a good sign that Maemo is getting all the deserving attention and many of tech experts rated the platform even more better and stable than Android itself about the features and flexibilities (iPhone not in category). Definitely, its moving well to push Symbian behind, if Nokia places its steps right.


nokia-n900_003

Why its being called a complete tablet device?

Tablet PC was a concept for a lightweight devices, which could be used in environment that are non conducive for keyboard/ mouse usages and provides all kind of connectivity options.

Nokia N900 defines the Tablet PC with both the input options; physical qwerty keyboard and touch screen and continues to offer every kind of connectivity options ranging from GSM to Wifi. (Right now, its not shipped with Handwriting recognition like Nokia N97 or even my Nokia 5800, but its likely to be included in next updates). In addition, its equipped with excellent stereo speakers, a brilliant 800x480 screen and 5MP camera for stills and videos. All this in a package of 181 g.


What so special about Nokia N900?fm radio

Its not first pocketable Nokia device running Linux; N770, N800, and N810 already ran over Nokia’s Debian based Maemo Linux distribution, but what makes its special is updated hardware and most importantly addition of cellular connectivity. So, if you have a data plan or best if 3G one, then you have an always on and connected to internet device in your pocket, which wont make you feeling missing your iPod or Digital Camera. It has the hardware to support FM radio, but as they are still in process of building a perfect FM Radio app, currently no FM radio app is included.Nokia-N900-vs-iPhone-3Gs

It got the same ARM Cortex-A8 processor 600 Mhz with 256 MB RAM, 3D graphics accelerator with OpenGL ES 2.0 support and 32 GB storage as best of iPhone 3GS and arguments about accurate resistive touch screen Vs flashy multi touch capacitive screens will be continued, but real deal breaker for geeks is root/ssh access to the core of the OS (although for security reason, its not enabled by default and requires two packages namely rootsh and OpenSsh) and an open source already known OS to install all kind of apps.


“ Just imagine…. completely unlocked phones with sure better battery life than iPhone 3GS or Android, SSH access for accessing your servers remotely and running services like normal putty access and editing file via VIM, even viewing the desktop sessions via VNC Viewer, accessing even windows desktops in traditional ways with rdesktop, running apt-get to install all kind of software, customizing configurations, writing custom scripts for tasks, incremental updates, reading PDF manuals via PDF reader, watching movies on higher resolution … .. I have tested these all till now and ……. Ohhh!!! I am really excited about possibilities and same time sad that after two weeks this device will leave me :( Just check below; remote desktop for Windows/ ssh for Linux “

rdesktop to Windows ssh to Linux Server

Yes!!!! I have read somewhere that with more than 1, 40, 000 apps in iStore, one has same number of reasons to go for iPhone, but just imagine, you have a real Linux Phone in your hands. The operating system, we geeks already know much about, the OS which could customized in as many number of ways as we could imagine. Needless to say, 1,40,000 would be a much smaller number, once Maemo gets full attention of Linux Developer communities. Moreover, it already has many packages, which we were used to see on debian linux, just waiting for your apt-get and honestly tell me how many of those ‘140000 apps’ actually get used by people? Just check the link for the facts.


What it offers and for whom?

Over the time, Smartphone users, their requirements and N900 could be classified in some categories like given below:

  1. Trendy Youth: A show off kind of trendy look, seamlessnokiayouth integration with Social Network Clients, IMs, fast typing options, smooth and consistent UI, stereo Music, FM, decent and fast camera, huge storage for mp3 and videos, big screen with high resolution and crisp colors, snappy browsing experience. 

    Nokia N900 offers a high tech and cool look (though a little bit heavier), social networking widgets could be kept on home screen to be always updated about happenings over them, in-built services of Gtalk and Skype, qwetry keyboard and auto complete typing options with intelligent learning dictionary makes typing experience brand new, a glassy UI like never experienced before with Symbian, Stereo speaker with excellent quality, FM Transmitter that will let you even transmit your own songs (FM Radio apps about to come, not yet included), 5 MP Camera with flash, 32 GB Internet Memory/ 256 MB RAM/ 1 GB application memory and option to add storage up to 48 GB more by cards, 3.5” resistive touch screen with 16M colors, 3D graphics accelerator with OpenGL ES 2.0 support and 800x480 resolution, added support of Flash Player 9.4 for exactly desktop like browsing (it runs even flash heavy farmvilla, which I dont think any other Smart Phone runs). Its support for video format could be extended by installing codecs. I was able to play various format movies (popular avi’s) by directly copying into it.

  2. Business Users: Push Mail, Connectivity options likenokia-n900-hands-on-11 Bluetooth, 3G, Wi Fi, qwerty keypad, flawless desktop like browsing, built-in VOIP and IMs, PDF/ Doc viewer, extra-ordinary signal reception and battery life. Top of that a much stable OS and decent backup options, convenient and accelerated charging options.

    Nokia N900 offers extensive mailing options as I found while configuring, push mail for exchange got upgraded by last update, connectivity options are maximized with all the options available, flash enabling, high resolution big screen browsing also got a big push by additional option of installing Firefox for Maemo, PDF Viewer is included, although I have to test yet, but installing Open Office must be possible with touch support, signal reception and battery life has been outstanding even when I was using it on always on Wi Fi and 3G connectivity, impressive is its handling of various connections automatically (it surprises me the way it handles switching between Wi Fi to 3G and then to EDGE), Maemo seems to be not only pretty and glassy but a rock like OS, there is also a backup apps included to take time to time backups, charging could be done by connecting to USB and mini USB charger has also been provided, more is a convertor that could connect older thick charger of Nokia or recent slimmer one to this USB model. Data transfer speed stands amazing. For transferring a 700 MB file in storage made, the time taken by it was less than a minute. 

  3. The Geeks: All the requirement set mention in above two categories, R & D and customization options, programmability of device as per needs, full IMs and uncompromised connectivity options, In all, a device which could be termed a complete in-control PC in their hands.

    Nokia  N900 offers root access for the OS, linux console, same architecture like debian means same way of playing with scripts and services, possibility of altering widgets at low level, possibility of configuring the logs in certain way, built-in VOIP and IMs like Gtalk and Skype could be kept always on, connectivity is automatically handled in very beautiful ways, its equipped with a full broadband speed provided with wireless, adding various apps and options to connect windows/ linux servers via telnet, ssh, scp, vncviewer and rdesktop makes this device something like never seen before. For me, in geeks section, no other cellular device in the world comes near to this one. In someone’s words
    “It's a true mobile powerhouse in every sense of this word, wrapped in a very eye-candy and functional UI at that."

    You can see the following video for a glimpse of possibilities with it for geeks, the world is sure about to change:


Things which make me go crazy about it:

  1. Keyboard: Honestly speaking, I never liked Blackberry kind of qwerty keypads and just sight of landscape qwerty keyboard was a treat. Still I was doubtful that if my finger would be able to slide that comfortably on these small button, but the experience was quite amazing day by day. Now, I even could think of typing whole blog post over the same, something which never could have thought with some complete touch screen or somehow adjusted Blackberry kind of keys. Moreover, dictionary and auto complete typing makes your life much easier. I typed a name only once and when next time, I type a few words of the same… it completes the same.. impressive.

    Such a smooth experience with keyboard, I felt only once before with
    my Dell XPS M1530 Laptop’s keyboard. Although still I wish if I was having some Windows Key to come out of things (although Ctrl+ Back Space works to bring task Manager), some red key to kill all or some combination of keys to serve the same purpose.
  2. Display and touch innovations: Nokia used an interesting way in touch UI navigation. under any screen, if in place of clicking any icon, if you click next to that then it will bring you back on the earlier screen (might be confusing to few in start, but its really convenient style in deed). Its bigger display actually make it possible viewing webpages without compromising anything, a true out of the box browsing experience. I also learned a trick that if you move your finger clockwise, then it zooms in the screen and same way zoom out, if you move anti-clockwise. Smart. Big screen size makes this device a handy ebook reader, while you are travelling. I just come to re-read Three Mistakes of My Life from Chetan Bhagat over it in a journey.

    Screenshot-20100220-222842
  3. Connectivity and accessibility of the same: Although all the touch screen device from Nokia started the same way that we could access them by tapping on battery icon, but Maemo provides options to change the connection at your fingerprint always in easiest way. If not enough then it automatically switches between connections beautifully to keep you focus on your tasks only.
    Screenshot-20100220-223905
  4. Multiple desktops, multiple widgets: It was new and stylish feature with Maemo, which comes very handy in situations. There are four different desktop and any of them could be bring in or out by just sliding finger left or right. As many widgets could be added to each one of them (limited by widget size) and arranged accordingly. Like one desktop for news, RSS feeds and social network related apps,  other one for music, clock, calendar, temperature etc and so on..

  5. Easy, familiar and very capable apps: It was amazing to play a 700 MB movie copied from PC into it without thinking about format of it. Similarly found and installed many apps is very easy way, which I will cover in next phase in details (e.g. FM Radio app)
  6. Windows/ Linux like usability in your pocket: Its kind of panacea for we sysadmin’s and I bet it would be hard to resist many of us from not buying this considering its still maturing phase. With this, I am always live anywhere for handling any emergency related to my office servers. Just will stop the bile, will look for nearest coffee shop and will be sitting their to handling Windows related issue with help of rdesktop and linux related issue with traditional ssh and scp. qwerty keyboard don’t let you miss your lappy. Travelling much lighter now without laptops.


Things that Nokia N900 still lacks doesn’t has out of the box:

  1. MMS not supported as of now: Yes!! we thought iPhone out of question as it doesn’t support MMS and here we face with Nokia. Shocking!!! Reasons as Nokia people call it “Its first an internet device and second a phone, so was it was not not needed”. They are not clear about adding the capability later on, but there should be some serious reasons behind it. Although a little Googling landed me on the page, which figures out the way out with a package name fmms, although have not tried as it asked for four dependencies, so skipped it. Will try soon.
  2. FM Transceiver is here. Good!! But where is my FM Radio App: As I mentioned, its still under development to make it a perfect one, but again why not to launch a decently working one at least. It has the hardware and FM radio could be run by third party apps even now. But still we are in waiting to get some official app from Nokia. Checked out the app store, just needed to search FM Radio and its already there. Surprisingly amazing in clarity and performance with intuitive looks. One just need to slide right or left to change the frequency. Really Wow!!! Still headphone required to be plugged-in, why so?
    Screenshot-20100221-112453
  3. Be ready for bugs like other open source products: Although tested well by Nokia, but still the transition from a Tablet Device to a cell phone seems to be missing a few points here and there. We seen the earlier two issues are due to non development of official apps and here is a bug, which seems to be crucial for Indian market, it does not support USSD numbers like *141# or many like that.  Sometime likely to be resolved in next updates.
  4. Switching between Landscape mode and portrait modes: After being used to of other devices since Nokia N82, it was surprising to see that Nokia N900 remains in Landscape mode always, accept in case of incoming, where it changes to portrait. This feature is not only a style but is handy in cases. Have to see that when it will join back the road.
  5. No Support for Google Apps as of now: Being a new platform makes you suffer a few things. There are almost no Google apps for Maemo, though all apps supports (Google Docs etc) full functionality in their web versions.


The 1012 essential apps (possibilities are infinite though in few days, I figured out these a few), one shouldn’t forget to install on Nokia N900:

  1. Firefox: Although Nokia N900 already provides excellent browsing experience like Firefox and itsfirefox that good that I am not missing Opera 10 Beta here, but still those ones, who wish to have the almighty with them with complete sync with Firefox on their desktop, here is the Firefox for Maemo. Note that its around 12.8 MB.

    Download | Info
  2. FM Radio*: I already mentioned that this app not included in the shipped model as of now. Don’t Screenshot-20100221-112453know what are the exact reasons, but find this app just flawless and like never before. Just check the pics in upper section of this article. Really innovative. I also found the reception even better than my existing Nokia 5310 XpressMusic, Nokia N82 or Nokia 5800.

    Download | Info
  3. rootsh*: In console of Nokia N900, you can run a command “sudo gainroot” for gaining root access, but that requires that you should have enabled R & D mode. A work around is Rootsh package, which allows you to quickly run a command on the same command line without using a root shell (like sudo). Without this, I was not even able to do ping and after this, I am God. That’s what makes Maemo special.

    Download | Info
  4. OpenSSH*: As a surprise to me, SSH package was not included. I searched the app store and found OpenSSH Server and Client. Simple to install and now you are in command of your web servers or other Linux Servers remotely. Note that OpenSSH server will ask you to set a password, set it but don’t forget it.

    Download | Info
  5. rdesktop*: Its just awesome. I thought to have some way to remotely access and recalled my old mate rdesktop. Its here in app store. Install it and it was unbelievably smooth to operate on even 3G connections. I have given a screenshot in upper part of article. Its so cool to see mouse cursor moving along with your finger.

    Download | Info
  6. vncviewer: As I see, its just about recalling our Linux apps and finding their maemo ports. vncviewer vnc is an excellent application to interact/ show with user’s desktop on Windows/ Linux (provided vnc server installed and configured on other side) at the same time, when user is working. You could only watch or could yourself take control of the same or both of the side could work one by one. A must have for specially we Sysadmins.

    Download | Info
  7. JoikuSpot: As I discussed earlier, this is an application, which turns your Nokia N900 in a powerfuljoikuspot Wi Fi spot for your Laptop or even your friend’s at the same time. You know that how handy is that in Indian Scenrio even if 3G not fully available till now.

    Download | Info
  8. Recorder: Till now, I have not been successful in finding something could keep on recording your calls automatically, but this one could be handy to record the calls, although needs you to manually push it while talking.

    Download | Info
  9. OMWeather: Although there is number of widgets, which one might find handy for adding on any omweather of the home screens, but I find this one quite handy. Didn’t got accuweather one, but this one works well. Shortcut to install ForecaWether already there in applications, but I find this one very customizable and efficient.

    Download | Info
  10. Zoutube: The brilliant YouTube Client, which I would be trying to find for Symbian as wellzoutube . Amazing UI and I find it even better than Official YouTube Client. It even provides option for downloading the video being viewed (could be deal breaker for many).

    Download | Info 

  11. KOffice: Yes! that’s the beauty of Open Source Products, they can’t let you deprived of convenience of alternatives. Finally, we got KOffice Document Viewer here. Although its a huge 9 MB App and you needed to create an Extras-devel Repository for that. How to do that? Simply create a new repository with web address http://repository.maemo.org/extras-devel and you will find it there with name of FreOffice.

    Download | Info
  12. Google Latitude Updater: Another huge size app, with size of 5.8 MB around. But it brings my beloved Google Latitude to me. May be rough and naive kind of in front of Google’s one, but at least there is something, I could think of updating my location and keep myself tuned in. Like many other useful apps, you will find it right there in your Nokia N900 app manager after enabling Extras-devel.

    Download | Info

I could keep on talking about this amazing set for so long as set of possibilities are just …. but making me stop here. Will update more things like shortcuts, screenshots about it later on.

I am sure that iPhone might be history in front of it due to its openness in Geek community at least. Its not easy to lure, we Indian buyers on basis of EyeCandy only, we want something really solid that’s where Nokia always ruled. Thanks Paul for providing me this set for review. Its already an forgettable journey.

Google Buzz

“ Atwittergain as per my trend of being late into things, I am here to offer, what I think would be a comparison comment over the dark horse Google Buzz and well adored one Twitter. Google Buzz has really amazed many of us and seems to be filling the gap, Google tried to fit on many times, but failed. A service that didn’t created a stir like Google wave did for many months, but as of now, it really seems that Google finally got something, which it was lacking since long. “


Google Buzz:buzz Launched by Google on 9th February 2010, in many ways, is the boldest attempt from Google to get hold on Social Networking without compromising its ways of making things. Orkut and OpenSocial were already there and were effective due to their inherited simplicity, but still Google lacked that bigger media presence and fanatics, Facebook or Twitter has. We were encountering lots of Facebook and TweetThis button on blogs, but still from Google side, we had only few options like to add the feed to Google reader or the recent one a bookmark to share something on Orkut. Does that work?

Buzz is a stream of status updates, pictures, links, and videos from your friends. You can “like” these items and you can comment on them. And if you use Flickr, Picasa, Google Reader, or Twitter, you can also automatically have those items imported into your stream. And Buzz will recommend items you might like based on your friends’ activity. Much like Friendfeed (launched by Google earlier) na !!!! But its integration with Gmail has made it the biggest phenomenon happening around as it started with an already existing massive base of Gmail users (150 million or 15 Carore as per August 2009).


twitter-logo Twitter: Since its creation in 2006 by Jack Dorsey, Twitter has gained notability and popularity worldwide. It is sometimes described as "SMS of the Internet" The use of Twitter's application programming interface for sending and receiving text messages by other applications often eclipses direct use of Twitter. It has almost every biggest celebrity already on it and if we talk about numbers, then it has total 5.36 Carore users as of now (note that these are number for the ones with public profiles only)

Twitter is a free social networking and microblogging service that enables its users to send and read messages known as tweets. Tweets are text-based posts of up to 140 characters displayed on the author's profile page and delivered to the author's subscribers who are known as followers. Senders can restrict delivery to those in their circle of friends or, by default, allow open access. Ever since late 2009, users can follow lists of authors instead of following individual authors. All users can send and receive tweets via the Twitter website, Short Message Service (SMS) or external applications.


First of all, why social networking sites becoming so relevant?

Although I might be miserable while understanding the trend, as far I think the biggest reason behind success is,  it unites people withsocial_networking_sites1 similar lifestyles (or wanna be similar) together in the “university lifestyle”, someone can connect with a friend, view his/her pictures and there is a good chance that he/she will see their new friend the next day on campus or at the pub.  Many times these sites are not actually about the persons themselves, but about the things happening. You could get to know insides about a lifestyle, you always dreamed of, without even knowing the person having the same. Its not just about fun and time killing, but about feeling alive and talking to people in real than going to office and coming back from office in a routine, where we don’t even know our neighbors

In the similar way, it’s a medium where at least you could approach or get approached by people, you never seen or cant even think about meeting like someone layman like me wanna to give a message to SRK. Definitely, Social Sites have a reason to get popular.

How Twitter became such a big thing everyone is talking about?

twitter_bird_follow_me_big Earlier experts denied growth of Social Networking sites and later suspicious about Twitter, but it was all about simplicity. Facebook, MySpace, Orkut etc. create an almost living life online with an introduction, photos, conversations, friend circle and communities. But while in start, there is hassle of filling forms and thinking that what to tell the world about you, later on, in stressed life, it becomes a bigger and boring thing than you actually wanted.

Think, if you are feeling something very ordinary, special or just weird and wanted to tell everyone about, what you do? Mailing are old fashioned for these kind of things and if you are regularly sending such messages then likely to be missed. So what are the other options? Before twitter, there were basically four ways to do the same:

  • Send SMS to all your contacts (Its costly and embarrassing, if no one cares)
  • Change your Orkut/ Facebook/ MySpace status message (was a better and still relevant option as you wished to address friends)
  • Write a blog post (if you are not popular then nobody would even know about that)
  • Change your status in chats (Gtalk, Yahoo, MSN etc)

Twitter become just a solution from combination for all these things. It was kind of Internet SMS considering the limitation of words to express. It was not FaceBook or Orkut kind of .. it was not blogging, but was both of these thing for people having short time specially like celebrities. Moreover, concept of following someone on twitter was way different than accepting friend requests. Yes! now you were not able to distinguish between friends that whom to show photos and whom to not, but still it was solving purpose for many.

As suited and joined by Celebrities actively, it was bound to attract others due to its simplicity and once twitter clients arrived allowing you to tweet from cell over GPRS, it became a BANG.


Why am I excited about Buzz?

Seriously speaking, I been a fan boy for Google Services, due to their integration into each other and top of that simplicity in way only they Social Networking Image could have defined. Some of their product might not have gone for that much success, which they are used to, but the concept behind each of their product was never the bad one or threatening to other existing models. If you launch something exactly similar to others and advertise it so big that its the better then you are threatening, but if you made something, which actually raises standards and in place of putting points on board, then what you do look like you are doing for mass, for betterment of technology and living. This is what I feel about the way Google does things.

Still I will be critical about analyzing Buzz. Buzz is still as for me, is the kind of thing Orkut has in form of Friend Updates or kind of thing Facebook has (already they did a little over or it and Farmville, Mafia Wars like games had completely spoiled the meaning of it).


As I come to read few deeper articles about it, I find clear and bigger differences.

Google Buzz

Twitter

My Comment

Its about conversations. Someone buzz about something and other might wanna comment on the same. It creates a conversation.

Its kind of self centric, where you write your opinion or give voices to others opinion. Not necessarily, you reply to someone specifically, but write your own words for public. Its not like one-to-one conversations, but might be like conversation in some group discussion or kind of board meeting.

Both are special at their places. Twitter still relevant as its user base already self centric in the way twitter defines it. Chain of conversations are best thing that could happen to any blog/  micro-blog/ social networking and Google Buzz is headed in the same way, original Social Networking was all about, but still I doubt that how it will look like on a massive scale.

From the first hour it arrived, it started growing than any other could have, due to already established massive base of kind of most favourite email service Gmail.

It was new in its concept and since its arrival in 2006, it grwon on its own due to its uniqueness easiness and yet effectiveness.

Numbers and growth rate might say something else, but still Twitter is a steady thing. Buzz looks promising and good thing till we keep it out of context with twitter, but when will come on same scale, then they are going to carry two different definitions.

Its still inside your Gmail inbox, no separate site or link (though Google Profile is a richer version of personal pages now). Although it has been integrated into Google Maps for mobile, but still mobile client needs to be developed. Moreover, I don’t know if its possible to buzz from SMS.

Its a separate service, separate account, separate password to remember, separate website to login into. Still it has massive reach due to mobile clients developed for it. More of it, it’s available by SMS (charges apply).

Google Buzz has potential and Google is responding well to complaints to shape it better, hope people around world will raise all the points in tme. Sure, soon we will see clients developed and some way around SMS as Google SMS already available in some of the countries. Still I don’t think Google will step in something costing to users other than data usages. Its a wait and watch.

Like Wave, Buzz has many richer multimedia options starting from pics, videos to maps and docs. Thanks to integration of Google Services under one account name. There seems to be no limit over number of words in a message.

Twitter work over links and text. Although I have seen things about pics and videos but all from other sites. Maintaining too much content on different places is a hassle. There is a limit over the number of words entered in a tweet

Multimedia may make things complex and twitter succeeded on simplicity. Options are plenty, but it will be needed to be observed that how all things take shape on broader scale. Limit on number of words, keep it light weighted and straight without making confusions, while sometimes, one feel constrained due to limit, differnt perspectives.

Success of buzz lying in the way its bringing  users buzzing while they don’t even know that they are buzzing. Whole new generation, who avoided twitter thinking that why to hit upon another piece of web, when already into many. It will bring simplicity to many users as Gmail is already the one site they open on first.

Strength of Twitter is in the fact that it stands on its own without any huge thing backing it up, but the same might be weakness as well. For many things, it depends on others and its services has been down this many times that we see some sites like http://istwitterdown.com/ to check the status.

Definitely, the power of Google cant be ignored, neither could the fear among communities, who suspects that are we going to get another Microsoft? Still Google sure has the potential of handling much more heavier traffic successfully than Twitter could ever did. On the other side, Buzz has taken it from other end, it has to be seen that how people respond to it.

Many started talking about privacy violation once it was launched, Google tried to handle things quickly, but sure it highlighted that keeping everything on place could be potentially dangerous. Yes! I have to mention that there is option to opt out Buzz anytime.

Twitter has been a separate thing for everyone. You get an account in name as you want. Its integrated with services like LinkedIn on user’s choice, but still its separated from other services, which keeps it away from being a single point of failure.

Both the sides are right in their sense, but if we foresee the future, then Google is clearly working out everything with keeping the model of future’s cloud computing model in the mind. Yes!! Single account meant to be single point of failure and so more secured services and aware users are required, but same is for Cloud Computing, which is a must in next days.

Google must learn or might have already learned that this is not the good things and good technology that make things work for mass, but its lies in usability, reach and yet flexibility for everyone’s need. Many live in present only.

Lots to say, much could be said about … but what makes me excited about Buzz is that it made some of the people go live, who were still holding themselves from opening up. Yes!!! some may cry for privacy, but many of us out here want an open world and still if you want to be private then there are always options. Moreover, except the misfire of email exposing problem in start, Buzz is bringing only public contents, which will lessen the efforts of publicizing something.


At the end,  I wish to add whatever the response of others might be, I already started enjoying Buzz and pretty sure that its gonna to stay for long (As Wave, Friendfeed and OpenSocial doesn’t seem to be).

Internet Explorer 6: End of An Era

So, here comes the end of an era …

I was already wondering that how some of the old things we grown up with (even after introduction of many new alternatives) just don’t die. Like Windows XP! do we really had found any real alternative for the same, when the date of support expiration is already near? Now its turn of IE6 to go officially. Thanks for the pics Devilsworkshop

Google just announced that some of features in Google Docs and many other Google Sites and Services wont be available google_dumps_IEover Internet Explorer 6 and it made a big buzz across the blogs that Google made the final push to let this browser die, which still was holding more market share than chrome, IE7 or IE8, around 21% till the last December 2009.

Sure the link goes to the recent hacking incident, which was officially done with exploiting flaws in IE6, for which Microsoft later on released security fixes as well. Still many security experts and companies taken stand against Internet Explorer 6. German Government even issued advice to all of its citizens for not using any version of Internet Explorer including even the recent one Internet Explorer 8.  

Is it really so that only that hacking incident made IE6 pushed away? I don’t think so. Introduction of HTML5 has already pushed IE6 to become obsolete as Internet Explorer till its version 7 didn’t supported HTML5 and like Google sites, many of leading sites have already moved over HTML5 due to availability of wide range of more options. Like Google Gears, many of the services already started mentioning that you can’t use them from IE6. Its just this, Google Docs have became of huge importance in world of cloud computing and by ruling out IE6 shares in it, Google has made it somewhat helpless by now (very few can keep and actively use multiple web browsers).


Internet Explorer 6 was released on August 27, 2001, a few months before Windows XP. This version included DHTML enhancements, content restricted inline frames, and partial support of CSS level 1, DOM level 1 and SMIL 2.0. The MSXML engine was also updated to version 3.0. Other new features included a new version of the Internet Explorer Administration Kit (IEAK), Media bar, Windows Messenger integration, fault collection, automatic image resizing, P3P, and a new look-and-feel that was in line with the Luna visual style of Windows XP, when used in Windows XP. Internet Explorer 6.0 SP1 offered several security enhancements and coincided with XP SP1 patch release. In 2002, the Gopher protocol was disabled and support for it was dropped in Internet Explorer 7. Internet Explorer 6.0 SV1 came out August 6, 2004 for Windows XP SP2 and offered various security enhancements and new color buttons on the user interface. IE6 updated the original 'blue e' logo to a lighter blue and more 3D look.


The biggest reason behind the success of Internet Explorer 6, it was shipped with kind of most successful operating system till now, so if the OS was a hit, so was the perfectly working browser Internet Explorer 6. Later as tabbed browsing became more successful and people started shifting to firefox more, Microsoft pushed Internet Explorer 7 with their Windows Vista, but many experienced it slower than even IE6 and was not that well received. Microsoft still hoping the best to get its shares back with a much better Internet Explorer 8.

I expect more services to come forward to drop support with Internet Explorer 6 in next few days as few already done the same from behind silently. As I read in Devilsworkshop.org as well, is Gmail going to drop support for IE6 in next?

 

Making Zabbix Monitoring Server from Scratch: The Dummies Manual

“ How we system administrators work in case of any trouble? If something goes down or anything wrong would have happened and we get asked about how it happened? We just run into logs or try to guess what would have been happened, was it high CPU, low disk space or tremendous network traffic? Sometimes we get our answers, sometime not and we keep on saying ourselves that we can’t be everywhere to monitor each and everything all the time. But it’s the time to update yourself and get optimized. I went through a few of monitoring solutions and with their pros and cons, finally I got settled with the Open Source Solution developed by Zabbix SIA. ”

What is Zabbix? Before the configuration and installation part, I am starting with a little history.zabbix1_thumb Zabbix is a network management system application created by Alexei Vladishev in 1998 (public release in 2001) to monitor and track the status of various network services, servers, and other network hardware. Zabbix uses MySQL, PostgreSQL, SQLite or Oracle to store data. Its backend is written in C and the web frontend is written in PHP and javascript.

Zabbix offers several monitoring options. Simple checks can verify the availability and responsiveness of standard services such as SMTP or HTTP without installing any software on the monitored host. A Zabbix agent can also be installed on UNIX and Windows hosts to monitor statistics such as CPU load, network utilization, disk space, etc. As an alternative to installing an agent on hosts, Zabbix includes support for monitoring via SNMP, TCP and ICMP checks, IPMI and custom parameters. Zabbix supports a variety of real-time notification mechanisms, including XMPP.


Installation and Configuration to monitor Windows\ Linux Servers:

Although I tried and found it extremely efficient , but even then I didn’t went along with the wonderful easy install procedure made by Brendon Baumgartner, not due to some fault in that one, but due to inherent problems with I guess not stable yet latest version of zabbix. But I sure be waiting for BB to write other magic scripts in the same way to make things one Enter only.

Here comes the way, I followed to install zabbix in manual way over the servers.

Step by Step Implementations with details:

Base machine: As for most of Linux Development I choose, even here I am choosing CentOS as the base system to build the solution upon. One should go for at least CentOS 5.x as there are a few options not available with older CentOS 4.x. As per recommendation for CentOS, machine should have at least 512 MB RAM and decent processor, LAN card etc. and although not kind of requirement but the machine should has ample space in it to store logs for as many days.

As usually I do, installation was customized with 1GB swap, 200 MB of boot partition, all PHP/ MySQL related packages checked, all libraries checked, SendMail package checked. In next, as the installation will pull updates, packages from internet directly, so Ethernet configurations should be ready and internet should be working fine over the same machine. Also note that it would be around 27-28 mb download size in total while installation.

Pre-requisites for the installation:

First of all, we need to finish installation/ update of all required packages in reference with zabbix installation.

yum install httpd php mysql mysql-server mysql-devel php-gd php-mysql php-bcmath gcc net-snmp net-snmp-libs net-snmp-utils net-snmp-devel curl-devel

Once finished with this, one need to check whether the crucial components are configured to start with the system and are working well.

# service httpd start
# chkconfig –add httpd
# chkconfig httpd on
# service mysqld start
# chkconfig –add mysqld
# chkconfig mysqld on

Possible issues and resolutions first:

Need to check whether things are working fine.

# mysql –u root

This should leave one to MySQL prompt, if not then need to check. In next, need to check whether httpd is working fine (Apache is properly installed and configured). Type the IP Address of the target Zabbix Installation Server in browser from some other computer, if you are able to see Apache page, then its fine otherwise you will be needed to check things like SELINUX.

How to check selinux status?

Execute the following command:

# sestatus

If its showing it enabled, then could disable it by

# setenforce 0

To permanently disabled the same, we need to do some editing in configuration file, otherwise it will be back with the next boot

# vi /etc/selinux/config

The file must look like (after setting SELINUX=disabled)

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - SELinux is fully disabled.
SELINUX=disabled
# SELINUXTYPE= type of policy in use. Possible values are:
# targeted - Only targeted network daemons are protected.
# strict - Full SELinux protection.
SELINUXTYPE=targeted

Check if the browser started opening apache page after this, if yes, then we are done, otherwise should look down in /var/log/httpd/error.log for other possible reasons.

Installation and configuration steps:

Here I am assuming that you are using CentOS 5.x as base, otherwise the configurations might be altered.

# cd /usr/src
#wget
http://internap.dl.sourceforge.net/sourceforge/zabbix/zabbix-1.4.5.tar.gz
# tar zxf zabbix-1.4.5.tar.gz
# cd zabbix-1.4.5
# mysql -u root
# mysql> create database zabbix;
# mysql> quit
# cat create/schema/mysql.sql | mysql -u root zabbix
# cat create/data/data.sql | mysql -u root zabbix
# cat create/data/images_mysql.sql | mysql -u root zabbix
#
./configure –enable-server –enable-agent –with-mysql –with-net-snmp –with-libcurl
# make install
# mkdir /etc/zabbix
# cp misc/conf/* /etc/zabbix
# groupadd zabbix
# useradd -g zabbix zabbix
# chown zabbix:zabbix /usr/local/sbin/zabbix*
# cp misc/init.d/redhat/8.0/zabbix* /etc/init.d
# vi /etc/init.d/zabbix_agentd

change BASEDIR=/opt/zabbix to BASEDIR=/usr/local/sbin

change FULLPATH=$BASEDIR/bin/$BINARY_NAME to FULLPATH=$BASEDIR/$BINARY_NAME

# vi /etc/init.d/zabbix_server

Make the same changes as above.

# chkconfig –add zabbix_agentd
# chkconfig –add zabbix_server
# chkconfig –level 3 zabbix_server on
# chkconfig –level 3 zabbix_agentd on

Now, installing the web application….

# mkdir /var/www/html/zabbix
# cp -R frontends/php/* /var/www/html/zabbix
# chown apache:apache /var/www/html/zabbix/conf
# vi /etc/php.ini

Find resource limits section and change max_execution_time to 300

;;;;;;;;;;;;;;;;;;; ; Resource Limits ; ;;;;;;;;;;;;;;;;;;;

max_execution_time = 300 ; Maximum execution time of each script, in seconds

Also make changes for date.timezone entry, it should be commented, uncomment it and set it accordingly like in case of India ..

date.timezone=ASIA/CALCUTTA

At the end, start zabbix services

# service zabbix_server start
# service zabbix_agentd start

Add zabbix ports to be listened to the configuration of services.

# vi /etc/services

And put the following two lines at the very end of the file.

zabbix_agent 10050/tcp # Zabbix ports
zabbix_trap 10051/tcp

Zabbix Server console installation is ready to and web installation is ready to go from here.

After finishing all the above steps, now go to url http://IP_ADDRESS/zabbix (Here IP_ADDRESS is what you have given to the server Ethernet port)

It should ask for installation steps, if you have followed my steps exactly, then it must go like next, next only. After finishing all the steps, you will get a login prompt, user name will be admin here and password is blank. After login, go to profile link and change the password to whatever suits to you. Logout and login again. Click monitoring and then go to screens in second row. You should get five screens on the same page for the zabbix server itself. One screen must be having map only. Check that rest all showing you graphs or not. If yes, then server side work is done and you are ready to move towards adding clients.

Zabbix Agent Installation over Linux Clients:

First part is to download the appropriate zabbix agent package from the official page. I assume, your clients (Servers to monitor) are updated and have kernel at least 2.6.x (If not then choose the suitable package).

# yum install net-snmp net-snmp-libs net-snmp-utils net-snmp-devel curl-devel
# groupadd zabbix
# useradd -g zabbix zabbix
# cd /usr/src
#
wget http://www.zabbix.com/downloads/1.8/zabbix_agents_1.8.linux2_6.i386.tar.gz
# tar zxvf zabbix_agents_1.8.linux2_6.i386.tar.gz
# cd zabbix_agents_1.8.linux2_6.i386
# chmod 7555 *
# ./configure -enable-agent -with-mysql -with-net-snmp -with-libcurl
# make install
# chown zabbix:zabbix /usr/local/sbin/zabbix*
# mkdir /etc/zabbix
# cp misc/conf/* /etc/zabbix
# cp misc/init.d/redhat/8.0/* /etc/init.d
# chmod +x /etc/init.d/zabbix_*

Now, Change the binary location to /usr/local/sbin

# vi /etc/init.d/zabbix_agentd

In next, make the zabbix agent point to your Zabbix Server by putting Server’s IP Address in configuration file of agent

# vi /etc/zabbix/zabbix_agentd.conf

And as final step on client side, set up the services

# chkconfig –add zabbix_agentd
# chkconfig –level 3 zabbix_agentd on
# service zabbix_agentd start

Getting the graphs from data coming from agents:

You will see that Zabbix Server itself added in the WebUI. In place of creating a new monitoring scenario, first it’s easier to copy the same entries to the newly added Linux Servers.

Go to Hosts, create a new host with the name of your agent (whatever name you choose), select group as Linux Server, then put the right IP Address and set the tab below to it on IP Address and save.

After this, go to Items, from combo box at right top, select zabbix server, it will show up items already configured for zabbix server, you need to select all the items and press copy selected items to button at the bottom and then when it will show the list of all templates and hosts configured, choose the one, you just created.

From here, you have setup items to fetch data from agent, now how to use it. Go to graphs, from right top select zabbix server and copy all the graphs to newly created server. Graphs are ready from here.

Finally, make a screen to monitor. Make a screen of 2x2 and give it the name as per your choice. Once screen created, click edit. Then configure CPU Loads, CPU Utilization, Disk Space and Network Utilization graphs for the agent, you setup and you are ready to monitor your Linux Server.

Zabbix Agent Installation over Windows Clients:

I find Windows Installation easier in first part and little bit complicated in second part. First need to download the windows agent from here

http://www.zabbix.com/downloads/1.8/zabbix_agents_1.8.win.zip

Then install it and it will ask for server IP Address, give zabbix server’s IP Address. Now, go to WebUI of Zabbix Server, Create host/items/graphs/screens in similar ways and you are ready to go.

There are many features that are there in Linux Agent but nowhere in Windows one. One workaround is to use data fetched from Windows Performance Monitor (permon.exe).

For example: Network Utilization

Go to cmd, type typeperf –qx |find “Network” >c:\network.txt

Now, check the network.txt file created in C: drive, it would be containing the exact network resource/ variable name for bytes sent and bytes received.

Now, how to call it?

Go to C:\program files\zabbix agent\zabbix_agentd.conf

Add something like following lines at the end…

PerfCounter= Server1NetIn,"\Network Interface(Intel Pro Server Adapter)\Bytes Received/sec",60
PerfCounter= Server1NetOut,"\Network Interface(Intel Pro Server Adapter)\Bytes Sent/sec",60

Note that the value placed in inverted commas is exactly the same, which you must have obtained from that network.txt file. Restart the Zabbix Service from services.msc. Now, go to Zabbix Server WebUI, create an item in target Windows Server area with any name for Network and put Server1NetIn or Server1NetOut as key. Save item and you are ready to use it in your graphs :)
