Hello everyone, We feel terrible to inform you that our original exam grade calculation formula was erroneous. Now it has been replaced by the correct one. We apologize for any false expectations or other harm that this may have caused to you. We also updated feedback givers around midnight. Despite the tone of the news, we wish you a merry christmas and a delightful start for the year 2012!

We have published the final results at Noppa's Results page. The grade in the table indicates that you have completed all the parts of the course in an evaluable way. The students that have not given compulsory feedback may do so at the link below (deadline in the beginning of January). If you've got a note "see email", please expect us to contact you by Friday 23rd December. The records will be entered into Oodi as soon as possible (i.e. during the first week of 2012 at latest).

Dear students, This is a reminder for mandatory course feedback. If you have already done this, please skip this message. According to the policy of the department, the course feedback is mandatory for each student. Please provide the feedback otherwise we cannot give you final grade for this course. The feedback form is available at: Finish version: http://www.cs.hut.fi/cgi-bin/teekysely.pl?action=showform&id=T1105150-T1105150-s2011palaute&lang=FIN English version: http://www.cs.hut.fi/cgi-bin/teekysely.pl?action=showform&id=T1105150-T1105150-s2011palaute&lang=ENG Swedish version: http://www.cs.hut.fi/cgi-bin/teekysely.pl?action=showform&id=T1105150-T1105150-s2011palaute&lang=SVE

Dear students, This is a clarification that the final exam of this course has to be completed individually, no group work is allowed.

Please DO NOT add your exam file to the group directory. In order to maintain privacy between the students and help our own work, we have created student-specific directories to the SVN repository for submitting the exam. Also the students that completed their assignments alone will need to follow these instructions. To make sure everyone gets this message, we will not let you in to the repository until 18:00 EET today. You will need to checkout the new directory ("svn checkout"). Replace the end from your group SVN directory URL as follows: group assignments: /group{number}/ exams: /exams/{student_number}/ The possible letters in the student number are in uppercase. The same username and password will work as with the group directory checkout. A simple misunderstanding caused our failure to conduct this in any more clever way. We still want to stick to using SVN, as it brings loads of benefits to the course staff and should be a basic skill for our targeted student group anyway. We apologize for the inconvenience and thank the anonymous student that pointed out the issue.

The final exam sheet has been published under the "Assignment" tab. The deadline for submitting your answer sheet is 23:59 16th, Dec.,2011 (Helsinki time).

Dear students, There was some concern about the "open exam" of this course. It is organized like this: The exam sheet (PDF version) will be published on Noppa page in the evening of next Sunday (11th, Dec.), and the deadline for returning the answer sheet (also in PDF version) is 23.59 (Friday, 16th, Dec.). You can use whatever source for answering the questions, but DO remember to add references to them.

Please be noted that giving feedback is compulsory to this course. The course feedback questionaire is now open. It takes a few minutes to fill in the form. Thank you for your feedback!

Here are the links for the surveys. We apologize for being a bit late with the links, as they were promised already by Wednesday.

Dear students, This is a reminder to check your AWS account activity. You should do it today, as Amazon will do the billing monthly and today is the end of this billing session.

Regarding to the demo: * 20 min for each group, 10 min for setup and other unexpexcted issues. * We provide an p2p environment for you, just like the bootstrap node during the assignment. * You might be asked to search & publish contents in the network. * If you implement other features, think about how to present them during the demo.

Lecture for 8th, Nov, 2011 will be given by post-doc researcher Denis Shestakov, from Media Technology, Aalto University, and the lecture "Cloud Services" has been switched to 15th, Nov, 2011.

The SVN repository should now work again. If you tried to make any commits during downtime, please note that they didn't go through and that you need to try again. If you notice any malfunctioning or other peculiarities, please contact us using the course email address.

There will be a short break in the SVN service due to maintenance work. The break takes place within a few minutes and takes about half an hour. Apologies for any inconvenience and such a short notice.

Dear students, There will be a reception time for Assignment 1, which is 25 OCT, from 9:00 - 11:00 and 12:00 - 16:00. The location is playroom (A120), CS building. This is not a mandatory session and you can just come and ask if you have problems on the assignment 1. Another news is that we upgrade the bootstrap node and add several more nodes into the network. Now bootstrap nodes doesn't hold the testkey any more. This change will not affect your application to find the value. However, if you want to achieve higher score, you should consider the same situation, that is how to handle the QUERY and QUERY_HIT messages when your are an intermediate node.

Dear students, Since bootstrap node drops invalid message quietly, someone might have problem on debugging. Here we provide a sample pcap trace, which record a small talk of 2 nodes. hope it can be useful, check the link below or the assignment page to find the pcap file.

Dear students, Most of you have sent an email to us either for a team formation or for finding a partner, but there are some students in the name list, who we didn't receive any email from. No matter you want to do it alone or find a partner or you might not attend this assignment, please send us a mail. Thanks.

Dear students, Here is an hash implementation in C, which can be used to generate message ID in assignment 1 (of course you can choose other approaches). The link is http://www.azillionmonkeys.com/qed/hash.html If you use other languages, just freely choose utility hash libraries as you want.

Dear students, Our internal P2P network which aims to help you to test your application is open now. You can Access the network via connecting to IP 130.233.43.104 and port 12100, which is by default our bootstrap server. Try to send a Join message, you should get corresponding reply. Check the format of your outbound message carefully, because our node might drop invalid messages. One key/value available for test is: testkey/0x01105150 If you find any problem related to this environment, feel free to let us know.

Dear students, Please send your group information, or other question related to the assignments to t-110.5150[at]tkk.fi. This will insure your email reach all TAs and also our teacher.

Deadline for the first assignment is 31 OCT 2011, 23:59. This is a team (max 2 members) assignment. Remember to send your team information to us. The information of how to access our internal P2P network will be published later. Check the assignments page for details.
