Flashy SMS reminders for your Linköping University schedule

*** NOTE: This guide is very outdated and does not work at all any more. The University has redone the whole calendaring system. See my new guide instead. ***

Many people at school have asked me about the SMS-reminders I get about upcoming lectures at the university. Fifteen minutes before every lesson, lecture, or any other activity in the school calendar I get an automated reminder sent to my mobile phone.

Mobile phone The message I receive contains information like where the lesson is, what type of lesson it is, which course it is about, start time, duration etc. It has proved to be an invaluable system for not only reminding myself that the lunch break actually is over, but helps me remember which one of the hundreds of rooms I have to go to.

The beauty of the system is that all changes to the global calendar system are reflected in the messages I get. If you would print the schedule every week and keep it in paper form some lecture makes a last-minute move to another hall or whatever, and you will end up in the wrong location. The text messages show only the latest and greatest information, even if the professors would try to lure you to the wrong room. Above all, it is completely free, and it doesn’t cost a single Öre.

This guide is specific to students at the University of Linköping/Linköping Institute of Technology, but anybody using some kind of imported calendar in a Google Calendar system should be able to something similar by reading the second half of the guide.

It should be noted that the steps are no way trivial. It will take you 15-30 minutes to complete all steps, but a system like this is worth the trouble since it will save you from missing any important lectures.

The heart of the system is the new integrated e-mail, calendar etc. suite developed by Google that the University of Linköping recently started to use as their primary web-based communications platform. The system itself is really better than the old and ugly system that was used before. It seems Google know what they are doing, and they use modern web techniques in the right way, even though I less and less respect Google as a company. That last sentence was really only an opinion of mine and should not be considered a fact.

This new web-based system is called “e-GO”, which is a highly stupid name for a platform like this. Why, did the University of Linköping choose such an annoying name that has no real-life metaphor other than the pseudo-flashy “GO” which, I guess, is supposed to mean momentum and progress. I think it is quite egocentric, considered the fact that it is pronounced “ego” when you say it fast.

Anyway, e-GO is still quite a new system, so chances are that you are using the old e-mail system. On the 15th of October 2007, there will be a global migration, meaning that all accounts will use even if you want it or not. Before that day though, you need to perform a manual migration. The e-GO system is a prerequisite for getting SMS reminders, so you’ll have to migrade.

This document documents the necessary steps to use the e-mail system, you will find pretty much everything about getting e-mail up and running there, which is why I don’t repeat the information here. If you have not yet started the migration, do so! It takes a day or two for the automatic migration to finish.

When migrated, you create a password. Instructions can be found in the same document The above document discusses this as well.

All e-mail you receieve should now enter your e-GO inbox, and you can compose messages and have fun with your new system.

This is where the guide really starts.

The e-GO system can do much more than just e-mail. It has a calendar feature as well. Clicking on “Calendar” in the top left corner will make you disappointed, though. There is nothing to see except empty white boxes representing different days of the week. We will need to import the school calendar. The school calendar is a plain HTML calendar system that is quite dated, but perfect if you want something robust that works. I really hope that LiU will keep this system as an alternative to the e-GO calendar which, while flashy, doesn’t do well in print.

To begin with, you need to have your regular calendar set up, since we are still using this system, only using e-GO for presenting the information in a better way. Log on to the student portal with your LiU ID, click on Schedule, and follow the instructions. Remember to build your schedule by adding which program or courses you want to have.

Now we need e-GO to recognize your calendar. This is done by letting the regular calendar export an iCalendar file, which e-GO can import on-the-fly. When you are finished building the schedule with your courses and classes, click on “Settings” in the left-hand navigation.

You will now see the page “Settings for your web schedule”. Scroll down the document and find “External iCalendar schedule”. Click the button reading “Publish iCalendar scheudle”. Your calendar has now been exported in another format for e-GO to read. Scroll down the document once again and review the iCalendar settings. I suggest setting all details to “Complete” for maximum information. What is important here is to note the URL of the exported file. You can find it written out just above the settings. For example; my username is “jonfo596″, my calendar is therefore at:

http://webbschema.student.liu.se/en/~jonfo596/ical

Keep the window open or write the URL down, we’ll need it again in just a minute.

When you are finished reviewing your calendar settings, click on the “Save” button. Note that we are not using “Mobile telephone scheudle”. This is for browsing the calendar with a GPRS or 3G phone, not getting text message reminders the way we want to.

Now, login to e-GO.

Click “Calendar” in the top left corner. You will now be presented with an empty calendar window. Let’s import the calendar!

e-GO uses one calendar per import, meaning you have one separate calendar for the imported school schedule and one separate for everything else. You cannot modify the imported information, since it is stored on a different server at a different place. In the left-hand navigation, find the button “Add”, and then “Add by URL”.

In the box “Public Calendar Address”, enter the URL you got from the schedule export you hopefully still have. If not, it is something similar to “http://webbschema.student.liu.se/en/~user001/ical”, only change “user001″ to your LiU-ID. When you have entered the info, click on “Add”.

In the left hand pane, a red box should have appeared that reads something like “LiU schedule for <username>”. This is your new imported calendar. Just click on that box and you will be greeted with your school schedule, imported and ready! Browse around and play with this system, you will use it a lot.

We still haven’t got text messages sorted out, so let’s add the final magic touch to it. Click on the small arrow next to the box on the left-hand pane and select “Calendar Settings”. This is were you set all settings for this calendar. I would suggest that you change the name of the calendar to something more interesting, like “School schedule” or, if you like, “Grand Theft Walrus”. It is up to you. Click on “Notifications”, just above where you entered the calendar’s name.

Here is the control panel for the text messages. In “Event Notifications”, click “Add a reminder”. Here you can set reminders such as pop-up windows that alert you if you are logged in to e-GO when the reminder is fired, or you can choose to recieve e-mail reminders. Of course, what we are out to do here is to get SMS reminders, but we will need to setup your mobile phone for this first. At the bottom of the page, click on “Set up your mobile phone to receieve notifications”. A dialog box might appear, reminding you that your settings have not yet been saved. Just click “OK”, we will return to these settings later on.

Now you are at the phone settings dialog. Select your country and phone number and then click on the box “Send Verification Code”. A box will appear, telling you the verification code sent by you via SMS is to be entered in the verification box. Click “OK”.

In a few seconds, your phone should receive a text message. If it doesn’t, check your country and phone number settings. Enter the code you received in the verification box and then click “Finish setup”. Google has now verified your telephone number.

Now you can select to be reminded via SMS. Select this from the “Event Notifications” settings box. I have selected to be reminded 15 minutes before each event.

This is it! Click on “Save” at the bottom of the page. Now the notifications should be up and running. Now set your personal calendar to use SMS reminders as well, so you can receive reminders for these calendars as well. Then you can try adding a new event to your personal calendar (again, the imported calendar is read-only and cannot be modified) that occurs in, say, 35 minutes. Then wait and see if you recieve a reminder for the event when you get closer to the event.

This cool and sleek setup is really useful, and it doesn’t require any work now that it is up and running. All events on the calendars give reminders, as time goes on new events will be added to later weeks, and everything is automated. Just sit back and “relax” during lectures.

But what if it doesn’t work? Well, there is plenty of help pages to resort to if you don’t find a solution to your problem here. There is a vast resource of documentation built into e-GO, just click on “Help” in the top right corner. LiU also has documentation regarding migration, a FAQ about the new system and some other stuff.

You are also much welcome to drop me a comment in the commenting box below! If you found this guide helpful I gladly receive feedback. You probably have some new ideas, and I welcome them too. Also, drop a comment if you run into problems trying to set the system up. I will do my best to help you out!

You can also ask me in persona at the university. I study the first year at Engineering Physics (Teknisk Fysik, Yi-linjen), so if you see me, just ask me.

Montag bin ich angefangen

Had some problems with the webserver on which the blog was running. It affected the XML feed among some other things, but the problems should now be solved.

In school, the Orientation Week is over. I now feel a bit more normal by not wearing that yellow tie around your neck. This week we begin two new courses. We had German class today. It felt good to speak my good ol’ mother tounge again, but I feel I need the practice. We didn’t do very much except talking about the course, learning to know each other and got the list of literature to buy. Apparently, we will use the same grammar book I had in high school for the fundamental grammar. Then I need to get a good dictionary and a workbook. The workbook is, according to our professor, the cheapest to buy directly from Germany. Books are a significant expense here at the university.
On Wednesday we have our first examination of two in the math introductory course. If I do well, I won’t have to do the big examination in January. But I feel confident that I will pass, the math has not been too bad so far. On Thursday we start with the linear algebra and during next week, Digital Electronics. The courses start to fill up the hours of the day, and it feels good to be study again. Just bring it on!

I have also found Lysator to be one of the best places to hang out in when you have got nothing to do. Music, computers and people. Perfect! I even feel like uploading a photo of what it looks like:

JAS, the final day

The ones who regularly read my blog probably know what “JAS” is by now. It means “killing” other people in a game simular to deathgame, but set at Linköping Institute of Technology is executed as a competition between freshmen at different programs at the school. During lunchtime during the four days from Monday to Thursday this week I and my team of six, all freshmen at the Y program, Teknisk Fysik och Elektroteknik, have been sneaking and running around the school for targets from the other programs to take down.

Back to Thursday. I had prepared a “space suit” to wear to get invincible. I had re-read the rules of the game and found that the space suit needed not to be a genuine to be effective, it only needed to be approved by your game leader. So I asked her if some aluminum foil with duct tape and a helmet would do it, and yes it would! In the game ,a “space suit” gives invincibility, so you need not worry about carrot “knives”, banana “guns” and apple “grenades” any longer.

Just before lunchtime I got dressed up, got the suit approved, and then it was time for some action! At 12:10 sharp the game started for its final 50 minutes and I started running around the school looking for targets. First off was a D-section student who I shot with my banana at the entrance of the C house. A few minutes later I met the rest of his team, who at the sight of me wearing the space suit, decided to run for it. I tried to follow them but was too slow in trying not to get the fragile aluminum foil destroyed. I later heard that most of them were taken care of by my team buddies who were waiting outside just then.

Shortly thereafter, it was time for running again. Just outside the C house I saw one final D student who was not killed by my fellow soliders, and after chasing him to a hedge he could not climb over, I thrust my carrot into his back, resulting in my second kill for the day.

Then finding targets got difficult. Apparently we had already taken out the whole D section team, and nobody else seemed to dare to show up anymore. I was walking around the campus for a good twenty minutes while getting the weirdest looks from people, especially the new exchange students who seemed to reconsider the country they had come to. I must have looked interesting in those reflective silver clothes, a bright yellow rally helmet from the 60’s on top of my head, a carrot held like a knife in my left and a banana held like a gun in my right hand, running around the area. Just look at how I looked:

My silver suit

Hey, I look so good I should change my name to Fuglesang!

Finally I found a TBI (biology) student who first stabbed me, telling me my suit wasn’t valid. I showed him the “approval stamp” on the back of my hand as well as the stickers the game leaders had put on me, before stabbing him back, scoring my third kill for the day. The space suit was approved, and there was nothing he could do about it. Following that event, I found nobody more to kill. At 13:00 the game ended for good and I went back to the headquarters and dressed back into normal clothes to get some lunch before math class started.

During all four game days I scored a seven kills total which seems to be one of the best individaul results in the whole game. As a team, though, we seem to be just around zero points in total, since deaths in your team score negatively. All of our team had a great time during JAS, and it definitely was one of the most odd things you could do during Orientation Week. I hope JAS will be the continuing tradition at one of the finest universities in Sweden; LiTH.

The “life badges” have now been collected and we are waiting for the results which should come on Monday. In the end, all our team agrees it is good to finally have the mission over with, since it was a mentally exerting task to perform warfare while having all the school work hanging over you. But in the end we all had really much fun!

JAS, day three of four

Day three of JAS.

Today we would go on our own, using “civilians” to distract attention. I wore my usual body armour and had a carrot and an apple for weaponry. Unfortunately there had been a mistake in buying weapons (read: fruit) so we did only had one banana for the whole team. I did also only get one apple grenade, instead of the usual two-three. At least I had two carrots this time to avoid death if I would lose my primary one.

I started in our classroom, sneaking through the corridors by myself. I used as many back doors as I could to avoid walking in public spaces and made my way to the U corridor. After ten minutes I reaced my destination and jumped in a classroom with a few Y students in. Friends! They were reading some math, and looked up when I entered the room.

I quickly saw something very interesting through the window. Outside, there were a bunch of D students with bulletproof vests about twenty meters from me. I dropped on the floor to avoid getting seen. Instead, I asked the fellow Y students for information about the D-students outside. How many were there? Did they wear red arm bands (meaning they are still alive)? Distance? The window on the far side of the room was open, so I removed my backpack and started to crawl on the floor while taking up my apple grenade.

My friends told me there were a bunch of them, but only one wearing the red arm band. Only one, and the throw is quite tricky. I decided that it would be worth a try. They did not at all pay attention but just stood there talking. I lifted my head to the window and had a look. Five D-students, one alive. It will probably be an easy target to kill!

I pulled the safety pin and threw the apple towards the group. This is were I made Huge Mistake #1 of the day.  I threw a bit to high, making the apple hit the last remains of the outstretching roof and bouncing off. The noise pulled all the D-students’ attention to my window and the guy with a vest that suddenly disappeared. I was out of apples and did only have carrot knives now, so a second try was impossible.

Only thing left was to get out there as quickly as possible. I grabbed my bag, ran out and, after a short hesitation, made my way to C4, a hundred meters away and probably far away enough for them to lose my track. I got there in very short time and hid my backpack under a chair. Now it was me alone and I would not give up without a fight.

I looked for flight paths. In the rear of C4 there are doors leading to one small corridor each. In the end of the corridors there are glass doors leading into the open. There was a handle on the door, but I did not want to use them since I though that it would raise the alarm. All other doors in school have pushbuttons on the side for opening. Huge Mistake #2. There later showed to be perfectly safe to open, had I exited there I would have been safe.

I exited C4 to one of the rear corridors and hid in the two-story elevator located there. I looked through the chink at the bottom of level 2 to see a few pair of shoes walking around. I heard excited voices and I quickly guessed they were my enemies coming to kill me. I knew they were one big group and only one alive, so probably they dead ones would walk in front to do reconnaissance while the alive one would be the one handling the killing.

I heard steps besides me, and a relay clicking. Probably someone clicked the elevator button and expected it to open. I decided that this was it. I grabbed a firm hold of my carrot and stormed out of the lower door. I stabbed they D-student in front of me, but he was just laughing. He was already dead. I ran up the stairs as quickly as I could, only to see a group of D-students smiling at me and pointing to the apple that had now landed at my feet. They got me.

My worst day, I did not score any kills. Probably the D students had found me through a tip from one of their civilian friends somewhere close who had seen me running into C4.

Phew. I felt quite hot of all the running and I needed to sit down to let my pulse sink to normal levels. My friends did not do too well, except for Christopher. He had killed two people. One with an apple grenade and the other one with his banana gun.  The others were also dead, except for one! He had been planning to stay home for lunch that day, saving his life for the afternoon game. After 17:00 he would start killing people with his carrot at München Hoben, a yearly festival held at LiU. The rules say that during München Hoben, only carrots are allowed, probably because the inability to fight more advanced weapons while intoxicated. I don’t know how he did tonight, but I will find out tomorrow.

We have also been thinking out a surprise for the last day. It is still top-secret, but it will surely be effective!

Over and out.

JAS, day two

The JAS mission has continued. We had been refreshing ideas and refining plans for the second day and it started at 12:10 on Tuesday. We had decided to go in smaller groups this time to avoid getting all our group blasted in pieces by one single apple grenade. I and two comrades started in the U corridor, two other started near the R kitchen (where I had planted a bomb set to go off at 12:11) and one guy was walking by himself, disguised with his red arm band on a red shirt to make it almost impossible to see.

One minute after the game started, we got a tip about one D-section student sitting in a classroom with a buoyancy vest at his side and not paying attention to the game. The three of us sneaked towards the door, covering each other flanks (like in a cool movie). I carefully looked through the door window to see two people sitting there. One of them was wearing a red arm band, symbolizing participation in the game, and the other was a so-called “civilian”. I looked over my shoulder to see if it was a trap or not, then produced an apple from my pocket, pulled the safety pin, and opened the door just enough to let the “grenade” through the door. Closing the door, I rolled over and took cover from the “blast” that followed.

I looked into the window again and saw the guy smiling dejectedly inside. I and my friends walked in and closed the door. His reaction was: “Very funny. Do you want my life badge? I just put the arm band on *this minute*”. I got my first kill for the day, but that was easy prey. What would come would test the aglity and endurance of all in the team.

My friends who had been guarding the door for attacks started to make their way out. After double-checking the corridor outside, they quickly ran out with me covering them. All of us made our way towards C4, one of the bigger lecture halls in the school. We walked alone in the corridor, checking classrooms on each side for possible enemies. Having a few meters between us reduced the chance of all of us getting caught in a “grenade” blast.

As we reached the intersection with the hallway outside C4, we stopped to look around the corner. I, now leading the way in the group, looked carefully outside and saw one D student clad in a buoyancy vest outside the western entrance of C4. D-students are easily recognized by their (ugly) yellow-and-brown hoods they are wearing during Orientatoin. I pulled my head back and told my friends what I saw. Probably there were a few other D-students there as well, holding the more open part of the hallway guarded. I looked around the corner again, seeing one more of them. They probably also saw me then because they were looking in my direction at the time.

Attack or retreat were our only options. Were we to stay, they would sneak up to us and throw an apple around the corner, making us easy prey. Instead we decided to attack rather than going back the same corridor as we went before. The distance towards them was probably thirty meters, giving me a chance to throw a grenade from about twenty meters while running. There is one way to take cover from apple grenades, throwing yourself flat on the floor before it “goes off” (i.e. comes close to you or touches someone).

I was to run first and the other would follow with a distance of a few meters in between. I put my carrot (knife) in my pocket, easily reachable when I needed to. Since one of the guys was wearing a buoyancy vest just like me, he and I were invulnerable to the banana gun. Three, two, one, go!

I ran, with a banana in my right and an apple in my left hand. I pulled the pin almost right after leaving the corner, thrusting the apple forward towards the D-students (which there were only two of, I noticed).  They both stood at the end of the larger section of the hallway outside C4. As soon as they saw me, one of them threw a grenade at me, forcing all of us to throw ourselves flat to the ground. I aimed my banana on the guy without the vest, easily taking him out. The other guy would be harder to take out, either an apple grenade or a carrot knife was needed.

I did not have anymore grenades to throw now, so I continued pacing towards the last guy. He threw his grenade, I jumped down even faster, avoiding the explosion. Now we were really close, I started to make my way up when I saw him running towards me. I reached for my trusty knife, only to find it had disappeared! Probably I had lost it while avoiding the grenades. Another split second passed. My two friends behind me were catching up, readying a grenade. The D-student ran even faster and when he came up to me he thrust his knife into my shoulder. I was defenseless without a weapon. Half a second later the closest of my friends launched his grenade, only to find it going too short and killing himself rather than the enemy!

Now it was a battle of one vs one. Both had bulletproof vests, so it was a match of carrots and apples. The D student threw a grenade so hard in the ground that it splashed on the floor. I shouted, but it was alright. My friend had thrown himself on the ground already. He prepared a grenade of his own, threw it towards the enemy and killed him.

When the apples stopped rolling and we all just stood there for a second we realized that the area was filled with about forty outsiders, looking up from their study books to look at us with the weirdest looks. Five guys in their twenties were running around in buoyancy vests, throwing apples and wielding bananas while shouting on each other. It was a most funny situation. I did not have much time to think about it now, one of our men was still alive and he needed to be protected. I quickly showed him the way into C4, calling the D students to follow us. This tactic is to prevent other enemies from attacking us while exchanging life badges and trophies. Not doing this caused us to lose three men last day.

In C4, we got to laugh a bit and the situation returned to the friendlier side again while we exchanged the proofs of death to our enemies and vice versa. The three of us took out the two of them, but we lost all but one in the fight. I got my second kill for the day, a kill that resulted in me myself dying.

We said goodbye to the D-students and I and my dead friends took our arm bands of to show we were out of the game. Still, with the bulletproof vests we looked like soliders on the move and were very valuable as decoys to protect our alive friend. As we passed the hallway in which the fighting had occurred only minutes earlier, I assured everbody that the situation was under control and that we in fact are fully normal. Sneaking through the Colosseum we made the way to the C-race, the lunchtime activity for the day. It was located in the slope of marks, just outside the other side of the C house.

Crossing between corridors and classrooms we made our way. As we exited the C house and almost were at the C-race, we saw two TBI (technical biology) students walking away from us with red bands on their arms and not keeping lookout. The three of us started to cross the square and making the way towards us. Discussing the plan, we did not go quickly enough and drew some attention to us because of our looks. When the plan was decied we started to run the fifty or so meters that remained to the TBI students. After just a few meters, I heard a thud on my left. Looking there, I saw my alive friend being hit with an apple grenade, taking him out with no more to say. All three of us were now dead.

The source of the flying apple was another D-student, still alive, who saw us standing at the square discussing and then as we ran, he threw the apple at us. The TBI girls had now seen us and charged at us, not realizing we had already been killed. They did not see the D-students that had killed us, and so there was another flying apple and they joined us in death.

That ended my second day of the JAS mission. My friends did not do so good. The bomb that was set to go off at 12:11 did go off, but no people involved in the game were close enough to get caught. The team members that kept guard there had been spotted by a few civilian TBI students who, by phone, had directed their army towards them. An apple rolling around the corner finished off the two in my team that were guarding the bomb.

The civilian team member had been more successful. He had been infiltrating the C-race, using a civilian wearing a buoyancy vest as a decoy walking five meters in front of him and pulling all the attention to himself. When two other TBI students saw the decoy, the threw an apple towards him, giving the real solider time to kill one of them with a carrot before getting shot with a banana.

In total the second day, our team scored four kills and six deaths, scoring -2 for the day.

It is really fun “playing war” like a six-year-old when you are almost twenty. We probably have the most interesting mission of all students, killing other sections. Many of my friends in class have expressed that they rather would have had our mission than what they are doing (for instance, cheerleading when the Y-section competes in competitions and races like the C-race).

Wednesday was going to be even more interesting…

The JAS mission, day one

During the Orientation Week (nolle-p) at larger Swedish universities, students get together in groups and get specific missions to complete before the week is over. It could be anything from being “cheerleaders” when your section competes in one of many competitions (like the “packling”, where you cram in as many freshmen as possible into one Nissan Micra) to do a funny prank to one of the other sections (preferably the I-section).

I got my mission last week and I and my group have been preparing the whole weekend. The mission is called “JAS” and is a competition between all the sections of the Institute.  It is very similar to the Swedish thing called Deathgame. Basically, it means “killing” other people in other teams with a variety of weapons; Knives (carrots), Pistols (a banana), Hand grenades (apples), vaults that you drop on people’s heads (cushions) and timed bombs (anything that counts down and then rings). “Killing” is only an imagined death, nothing happens for real, of course!

The “armY”, the Y-section JAS group, consists of me and five other people that have the mission to take down as many soldiers in other JAS groups without getting killed ourselves. A kill is, for instance, (gently) stabbing an opponent in the back with a carrot. The opponent is then killed and you are awarded the user’s “life badge” for the day. He writes his/her name on it and you write yours, and that scores a kill.

Every kill means one more point for your team, and a death means minus one point. The game is on between 12:10 and 13:00 and 17:00 to 07:00 the following day, meaning that you cannot kill during school hours (except for lunch time, tee he). If you die you get resurrected on 07:00 the next morning, and you have one life every day.

Weapons are not the only things that can be used. Wearing a bullet-proof vest (a buoyancy vest, flytväst) means you are invulnerable to the pistol bullet (i.e. the banana), and a bike helmet protects against vaults dropped on your head. Full body armour is available if you have a real spacesuit. That means a genuine, real, spacesuit.

Back to today. Monday was the first day of four in the JAS game. I and my group, armY, have been collecting buoyancy vests, bike helmets, apples, carrots, bananas and timers from our classes to get equipped with all the deadly weapons needed for successful killing. I arrived early for school, went into the big lecture hall C1 and planted my mobile phone to ring at 12:10 and kill the I-section soldiers that were to finish their math lecture there by then. A successful “terrorist bomb” would mean taking out all of them, giving many points to armY. I left C1 after successfully planting the device well hidden in the A/V equipment.

Hours passed as the clock slowly ticked on to lunchtime. Around 12:10 our team gathered outside C1, equipped with the obligatory red band on your arm (a signal that you are part of the JAS)  and “bulletproof vests”, “knives”, “pistols”, “grenades” and helmets. The clock turned to 12:10. The slaughter is on! I-section students started to exit C1, and we waited for some kind of reaction from their team that, according to our plan, were supposed to succumb in the “explosion”. We made our way into the hall as the final students exited. When we entered only one student remained, and there were no signs of the “explosion”. We asked him about what had happened, and he told us that the bomb had gone off at 12:06, before the game had started and that it didn’t qualify for a kill. Apparently the clock on the phone was incorrectly set.

Sigh. Our grandiose plan to start off the first game minute so boldly was shattered to pieces.  There was nothing else to do than to exit the building, starting to look for easy targets as we went towards the dining area. We paced forward between the buildings passing a lot of civilians until we saw what we wanted. A group of D (computer science) students were gathered at the corner of house A talking and they were all wearing the red arm bands.

I and my friends ran towards them, I pulled the “detonator pin” (the stick) from one of my apples and threw them towards the group. It landed near them and would have been counted as four kills if they would not already have been killed by a third soldier standing nearby. Apparently he (an I-section student, of course!) had already blown all of them except one to pieces with the apple grenade. The D student that still was alive ran away from the apple before it landed and he charged me right on. He fired his pistol, forgetting that I was wearing a bulletproof vest that made this attack impossible. I ran towards him, pulled my knife (carrot) and stabbed him in the chest, making my first kill!

After I got his life badge my friend shouted to me that a few unsuspecting I students have been spotted between house C and Kårallen. We quickly regrouped, ran towards the point crouched behind one of the hedges that lead to the place. I saw one of them leaving the area, I jumped from behind the hedge and got  him with my banana pistol. My friend had at that time thrown an apple towards the other person, scratching even one more  I-student off the list. The three of us that were gathered rejoiced and were taking care of  the life badges when another I-student ran from behind another hedge, throwing the apple towards the two of us that were still alive, shredding us to pieces. I died.

Meanwhile, in Kårallen (where special rules apply; only carrots and vaults allowed) another team member was illegaly fired upon with a banana gun, making the kill invalid. He paced out to us, borrowed a carrot from me, ran back and stabbed the guy just as he stabbed back on my friend. They got each other.

All of this happened in less than ten minutes. Everybody in our team except one strong survivor died in combat, but the four kills we got gave us in total zero points for the day. I am now dead until 07:00 the next morning, but now I proudly wear two black strokes on my Orientation Week tie, symbolizing my two kills.

Tomorrow will be even more interesting. We have now decided upon quickly leaving a place as visible as where we died because of the high risk of exposure from other teams, as well as some new tactics. If you happen to be at LiTH this week and see people running around in dark sunglasses, bike helmets, buoyancy vests holding bananas and carrots in their hands; don’t worry. It’s probably us going for another kill.

Call for aid!

If anybody reading this blog lives in Linköping or attends the Linköping University and has either a computer cable for the Canon PowerShot G2 or a CompactFlash memory card reader (USB or PCMCIA)  I would be overwhelmingly grateful to you if you could borrow it to me for a few hours. I want to be able to download my photos of the past Orientation (nollning) Week at Y-linjen to my computer and eventually publish them on the blog.

The news value of these photos are deteriorating quickly and I would really like to have them here on the web.

You can either drop me an e-mail, a blog comment or meet me in persona at the university tomorrow.  Thank you!

Memory slot updates

I have recieved a few e-mails about the progress since my last post about the Thinkpad T30 memory issues. I went to the electronics workshop to check up what they would charge for resoldering the motherboard slots. Since they have hourly rates around 300 SEK/hour (~32€/hour) the price would land on either 300 or 700 SEK, but they wouldn’t give any warranty for assuring the machine would work afterwards. I felt the price a bit too expensive and didn’t want to risk this machine, not yet at least.

I went home and waited, and finally the new memory slot cover that Lenovo sent me arrived. The new cover is much more rigid than the old one, and has like a square emboss over it. This allowed me to put a few pieces of paper under it to apply pressure on the slots, making them work. This worked for a few days and then it didn’t again. Probably the solderings get worse when I try to do this, so I have stopped applying pressure to the slots. Now there seems to be no solution to the problem of the broken memory slot than to do a real re-soldering.

One finnish guy, Hobbymat, responded to the last post and wrote the following about re-soldering the Thinkpad:

Greetings from Finland! I have repaired a few T20/T30 series Thinkpads using a very fine-tipped soldering iron (a Metcal, a Weller will also do) and a stereo microscope. In my opinion the memory slot repair procedure does and should not need application of any extra solder as mixing different solder metals (conventional tin-lead mixture used in older Thinkpads or lead-free tin-silver-copper solder used in newer Thinkpads) is not recommended, and it is rather difficult to tell which solder has originally been used. Actually the needed amount of solder metal is already there in the joints – the only problem is that there are cracks that do not conduct electricity any more.

However, it is advisable to use liquid soldering flux applied to the solder joints with a small brush or a “flux pen” prior to re-heating and melting of the individual solder joints one by one. The flux penetrates the cracks in the old solder joints and it will help to remove the oxide layer in the crack when the existing solder melts, producing a good-as-new solder joint.

As spotting all the broken memory module slot joints is by far not easy even for a professional with the best available equipment, it’s best to fix all the solder joints if you decide to go that way. There are as many solder joints to “flux and re-solder” as there are pins in a memory module. That is, 144 joints for a T21 or 200 joints for a T30, and you’ll need to double this number if you are going to use a memory module in both slots! But it can be done, given some time and patience.

This repair procedure is suitable for a skilled electronics hobbyist with access to the tools mentioned above. If you don’t have a stereo microscope, you can also use a jeweler’s loupe, good loupe glasses or a very good magnifier for viewing the work area. However, most likely you can’t spot ANY of the micro-fractures of the solder joints unless you have a decent stereo microscope with a magnification between 10X and 40X. Of course, a very steady hand is also needed for this repair job!

Hope this helps someone :)

All I need to find now is a skilled solderer that can do this for some cheap money. Since I now live in Linköping it should not be too difficult to find somebody at the Institute of Technology at which I now am studying.

Please comment if you have ideas or other things to add to the discussion about the Thinkpad T30 memory slot failure.

I have taken many photos the last week, but since I left the computer cable in Västerås I am unable to download them to my computer. I therefore have no photos to show you.

Anyway, I just came home from the “HaYk”, a one-night hike with all new students in the Engineering Physics section. I am a bit tired since the mosquitoes harassed me even though I brought my new insect repellent. Probably this new icaridin stuff doesn’t really work as well as it should. I was half-asleep and felt the little blood suckers landing on my hands and face, sucking the juice out of me. I had to ask my friends for some of theirs. Badly enough, the only thing that was available was citronella oil, that the owner had bought in Sri Lanka. I applied the oil, and the herbish smell was really strong but it seemed to work fine for the moment. I miss my now-empty old trusty bottle of DEET.

I’m beginning to realize that I am a little too much interested in insect repellents… why am I really writing this? 

People have been commenting  that they feel it strane to see a new student at LiTH blogging with Lysator after four days at the school. They obviously don’t know that Lysator really is the grandest and oldest of all computer clubs in Sweden, and for a hacker like me, the best place in town to meet other people like me. So there you go!

New school week begins tomorrow with math lectures. I am really keeping up with the pace and am still ahead of the scheudle. I got the first hand-ins back the other day and they were all correct! I never thought it would be that easy.
