Sad state of affairs in IITK

with one comment

This institute’s administration is as pathetic as it can be. Most people in the administration work without thinking even a little about what they’re doing. They give you the “I was told to do so by my superiors” line even when it is clearly visible that they don’t understand why they’re doing it. Let’s start with something as useless as the SiS. SiS is a private security organisation in the campus. They do some of the most stupidest things possible and whatever they do, the thefts continue to happen. A week ago, in a neighbouring wing, 3rd storey, a theft occured late in the night. Sunil was sleeping with his door open (the weather is very hot and humid these days) for the cool air to drive out the heat and humidity from his room. He didn’t expect a thief to go all the way up to his room in the 3rd storey and steal his whole wallet (maybe a cell-phone was lost too). His wallet not only had money, but his institute ID-card. Yet again, the SiS fails.

If you happen to have a laptop and use a typical long-strapped laptop-bag, you’re in bad luck. You’ll be asked to enter your name, time of entry and exit, and sign in a worn-out register every time you visit your lab or leave/enter your own hall. God only knows if those guards make any sense at all of what you’ve written with your hands which are more used to computers than a pen. The funny part is here: carry your laptop in a backpack kind of bag and they won’t ask you a thing. Carry even an empty laptop-bag and you’ll spend two minutes explaining to them that your bag is empty.

Hall 1 has three gates. One of them is open round the clock, the other was sealed off by the Director some years ago during a summer (no idea why it was done even though it’s the closest gate to the academic area) and the other one, that is closer to the CSE lab area, is closed after 22:30. Now why does this happen? I don’t really know. Many of us who leave the lab long after 22:30 are out of luck, we simply have to walk all the way to the gate on the other side of the Hall. Back in my old school, we had security cameras which could rotate in any angle and monitor movements. I wonder why a “high-tech” institute such as ours never considered that over the mostly useless SiS.

Let’s get to the UG office now. Nobody can be more annoying than these pricks here. They fail at even counting the number of backlogs you have. This particular “Programme Advisor” (yeah, right) of the Y4 batch who even signed my manual-registration form last summer for a science-elective now claims that SEs aren’t offered during the summers and therefore I’m considering this SE as an OE(!). I’ve tried explaining to him that I don’t have any OE backlogs and his stupid decision (which I think he made by himself) is shoving another OE down my throat. He refuses to talk anymore about it and asked me to get (yet another) letter from the DUGC.

I haven’t registered for any courses this summer, I didn’t want to go through this confusing, pointless exercise with these morons again. I decided to stay for another year and take it slow and easy, without having to deal with these monkeys. I really think Prof. Dheeraj Sanghi’s tenure as the SUGC was the best. He’s the kind of person who doesn’t mind thinking a bit, even if it breaks a little sweat. During his tenure, we could easily swap future courses from our template to-and-fro and do it the way convenient to us (very handy when your programme is a bit screwed and time-clashes or pre-requisite conditions doesn’t let you follow the prescribed course-structure). This time, the current SUGC (sorry, neither can I spell his name nor pronounce it, I just remember a “Ghost” in his name) refuses to think even a bit and let the students with backlogs do future courses from their templates that are offered during the summer. Roughly 40 students went empty handed because of this on the day of registration. Oh, and courses mysteriously pop out of nowhere at the last minute. One of my friends who spent the whole duration for which registrations were open running around never realised that a course he had a backlog in was offered in the last minute. By total chance he stumbles upon it from a junior whom we met when we were heading towards the CR for lunch the next day. More nonsense: instructors are supposed to evaluate the end-semester answerbooks and give out the grades in a time-frame of 72 hours after the end-semester exams. They do come up with grades and submit them to the UG Office and the Counseling Service. It’s been over a few weeks now and I still don’t know my grades. Only the ones I got an F in (I got one this time) were informed to me through my DUGC a few weeks after the end-sems. Thankfully, that was before the summer registration day, or people wouldn’t know if they could re-take those courses in the summer term. Couple of my juniors have a skewed programme ahead of them simply because they weren’t allowed to take a future course in the summer. The things that happen when the authority refuses to think and simply take the easy way out by following the rule-book or going by what their superiors say.

Talking about superiors, the Director is somewhat like a little Hitler here. There have been about 5 to 6 suicides (sense the apathy here?) in the campus during my stay here (4 years now). The Director has formed committees over committees and so has the Students’ Senate to come up with steps to take to curb these mishaps. The Director isn’t happy with any of them after the latest suicide (a few weeks ago, during the end-semester exams) and has taken decision making into his own hands and poof, no internet for you after 00:00 in the student dormitories. No internet – yes, no LAN – no. Although inter-hall LAN doesn’t work, intra-hall is still lively and dare I say, the gaming and late-night movie watching has increased! And, yes, most halls have their own direct-connect hubs now that function during the 00:00 to 06:00 internet curfew. People continue to watch movies, play games, whatever. It’s people like me who aren’t really into movies or games and use the internet for, again, dare I say, useful purposes that suffer. More on this at Arun’s post here. Sigh, all this makes me just as sick (or more) than it makes Arun. Even my friend from NIT-Suratkal who’s here for the summer doing a project says that his campus’s internet policies are way better. Heck, I don’t get it one bit, what is our adminstration thinking? They recently upgraded the internet bandwidth to 100MBps, removed the HTTP proxy accounting (you can download as much as you want! – it used to be 500MB per month, which was increased to 1GB and then 3GB and now -infinity-). Pirated movies, tv-serials, music, games, software continue to pour in in such quantities that there are two internal torrent trackers (and three main direct-connect hubs) in our LAN.

It’s a sad, boring, lazy life here. Most seem to have gotten over the internet-curfew already.

Getting Kopete to work* on KDE 3.x

with 2 comments

To work* – My work environment’s network is a LAN shared by about 2000 users. We don’t have the neat NAT’ed type connections or transparent proxy setups other universities in the rest of the world enjoy. Our access to the remaining world is through a HTTP caching proxy which supports connect-over-http.

Step 1:
$ sudo aptitude install tor dante-client

Step 2:
$ sudo vim /etc/tor/torrc

Have the following text inside it:

SocksPort 9050 # what port to open for local application connections
SocksListenAddress 127.0.0.1 # accept connections only from localhost


HttpProxy 172.31.1.233:3128
HttpProxyAuthenticator username:password


HttpsProxy 172.31.1.233:3128
HttpsProxyAuthenticator username:password

Step 3:
$ sudo vim /etc/dante.conf

Add the following:

route {
from: 0.0.0.0/0 to: 0.0.0.0/0 via: 127.0.0.1 port = 9050
protocol: tcp udp # server supports tcp and udp.
proxyprotocol: socks_v4 socks_v5 # server supports socks v4 and v5.
method: none #username # we are willing to authenticate via
# method "none", not "username".
}

You might want to allow from: 127.0.0.1/8 alone.

Step 4:
$ sudo invoke-rc.d tor restart

Step 5: Go to KDE’s Control Centre and enable SOCKS (select Dante) under Network Settings > Proxy

Step 6: Configure Kopete – use the ip of talk.google.com

Step 7: Get cursed for those extra-spaces Kopete sends by Pidgin users 😛

Been a while again!

with 3 comments

So, I’ve been away from blogging for a while now. Several things have happened around me during this period.

Formation of the SSCVC:

We called for what might have been the first informal Anime-club meet at the campus. Most of were present (bheekling was asleep) and presented our idea for forming a formal club under the Students’ Gymkhana. We hadn’t thought of a name yet and we hadn’t met people either. The following weekend, we arranged for a show in the hall1 TV room. We were a little late and some people had turned back. But then, we went and called some people to come and watch :D. We screened the first two episodes of “NHK ni youkoso” and “GITS: GIG 1”. (Lord Vash’s wide-screen and , BigBong’s laptop were used). We couldn’t bear it anymore and basilisk and I decided to meet Amitabha Mukherjee (a prof. in the CSE dept., who we reportedly heard from Nishant Singh that he was into anime(!), which turned out to be false). He pointed us to Satyaki Roy’s direction >_>. Next stop was Suchitra Mathur ;). Bheekling got us appointment and LordVash, himself and I met her. She was interested with the plan and all that and we still hadn’t come up with the name. I remembered Genshiken and how it was about an anime club. I quickly googled to get its full-form. It was the SSMVC – Society for Study of Modern Visual Culture. In a day, we met with Satyaki and he suggested that we change it to SSCVC – Society for Study of Contemporary Visual Culture. Woah! We still haven’t put out our proposal for the club yet. Hopefully the iitk-animesociety should help us out here 😉

Revamp of my data:

I have two hard-disks. Started off with a Samsung 160GB SATA disk three years ago. It had a warranty of period of one year as compared to Seagate and I yet went with it :\. Something I soon realised was that Samsung and LG were these two Korean companies that dumped junk in India for a while (only recently have they set up their own plants in the country and get decent products). Another thing being – to not buy computer products such as hard-disks, motherboards or CPUs in Kanpur (and maybe in the whole of UP!) . One – I have personally come across cases where a dealer takes screwed up disks from you, refurnishes them and sell them to someone else. Same is the case with mobos and CPUs. A model of RAM you bought at one time won’t be available a few months later (suppose you have 512MB and wanted another identical stick – tough luck).

Some time ago (during the summers, I think), I had repartitioned my data and set up ZFS via FUSE on linux. Wasn’t production ready and very shaky at times. Couldn’t share my whole data on DC++. During the past few days, basilisk had tried to install Gentoo and ended up cleaning up his 250Gb harddisk with Ubuntu :P. I transferred all my Anime, Movie and TV onto his disk, the Music went into a confidential location. Set up four partitions on my reliable ATA Seagate disk, one Boot, one Root (20GB), one Swap and one large Home. The other unreliable disk is one big reisrefs partition 🙂 Removed my FreeBSD and that extended partition windows had created. I had played around with FreeBSD too to get good ZFS performance before I removed it. Updated to 7.0-CURRENT and zpool segfaulted at zpool import :\ Considering the hassles I’d have to go through if I had stuck with FreeBSD amd64, I decided to stay with Linux itself. If at all I need to experiment with any of those at a later point of time, they’ll be on a different hardware :X! (Notes: don’t ask me how I went to 7.0-CURRENT from within the campus)

Food:

Yes, I’ve been eating mostly in the canteen or at the gate. I spent a lot of money. Just for food. (I payed off my earlier debts too)

Classes(!):

I haven’t been to classes for a couple of weeks. It’s a bad thing. It suddenly turned cold here and you feel like staying in your bed like nothing else’s important. Exams are coming soon – 8th Oct.! I have to do whatever has to be done. This sucks 😐 For now, I should try not to waste time on anything else (:P).
