<p>Hi,</p>
<p>Thank you for your answer about the plans! I think 20 minutes per
task is the better choice, since 3x30 minutes is already 1.5 hour
and then there's no time for demo. <br>
</p>
<p>It will be most likely not possible for my labs to follow yours,
because we still have to write the synchronous chat server as
well.<br>
</p>
<p>Also it was a good idea to request BEAD for yourself beforehand!
On Friday, I wrote Artúr about adding everyone, hope he'll manage
it before the nagybeadandó release (it's complicated because of
the students migrating). <br>

<div>Hi,</div>

</div>
<div>To be honest, I think Márk has really good tasks in this
area:</div>
<div>I have added an English translation to the tasks:<br>
</div>
<div><br>
</div>
<div>---<br>
<br>
Készíts olyan chat alkalmazást, amelyben a két kliensnek nem
kell egymásra várnia soronként, hanem bármikor beszélhetnek
egymáshoz, és ez azonnal kiíródik a másik kliensnél.
`AsyncChatServer.java` és `AsyncChatClient.java`<br>
</div>
<div><i>Create a chat application, where the two clients don't
have to wait for each other. Instead, they can talk to each
other anytime, and their message immediately printed at the
other client.</i><br>
</div>
<div>---<br>
<br>
Készíts chat szervert, amelyhez tetszőleges számú kliens
kapcsolódhat, illetve bármikor bonthatják is a kapcsolatot.
Minden kliens először a nevét közli egy sorban. A kliensek
bármikor beszélhessenek, ami azonnal íródjon ki minden
kapcsolódott kliensnél. `NamedChatServer.java` és
`NamedChatClient.java`</div>
<div><i>Create a chat server, where any number of clients can
join, and they can disconnect any time. Every client first
sends its name. Clients can talk any time, and the message
of a client shall be printed out at every other client.</i><br>
</div>
<div><br>
---<br>
<br>
Adott két szerver. Az első szerver két parancssori paramétere
egy cím és port, melyen egy második szerverhez tud
csatlakozni, és névként a `server` szót küldi át, melyből a
másik szerver tudja, hogy szerver kapcsolódott hozzá. A
kliensek csatlakoznak tetszőlegesen egyik vagy másik
szerverhez, melyekre üzeneteket küldenek. Ha egy kliens az
üzenetét elküldte egy szervernek, akkor az a másik szerverhez
átküldi azt, amelyik továbbítja azokat a hozzá csatlakozó
kliensek számára. `MultiChatServer.java` és
`MultiChatClient.java`</div>
<div><br>
</div>
<div><i>There are 2 servers. The first server can be started
with an address and a port as command line argument. These
arguments are used to connect to another server, with <b>server</b>
as a name. The other server knows from this name, that a
server is connected to it. Clients can connect to any of the
servers, and send messages. When a client sends a message to
server, it sends it to the another server, which broadcasts
it to all its clients.</i><br>
</div>
<div><br>
---</div>
<div><br>
</div>
<div>So here is my plan:</div>
<div><i>Please note, that my class is 10-12 Monday.</i><br>
</div>
<div><br>
</div>
<div>1) Give the video to the student. Latest this evening</div>
<div>2) First exercise is the one which the video is about. <i>I
agree with Tamás, that it could be homework, but I hardly
think, students would be ready with it by tomorrow morning.</i></div>
<div> 3) Once this task is done, they would get the next two
tasks.</div>
<div>4)Of course, there are faster and slower people in the
class. I would like to post these tasks in BEAD. (I have
already asked Artúr to create the group for me) I don't say, I
will go through each and every solution, because it is a lot
of time and effort. But I would like to give the students the
feeling, that they need to work, and they get real assignments
during the class.</div>
<div>5) And I would give 20-30 minutes for each task for them to
complete. Then I would go to <i><b>demo</b> mode, and show
them the tricky parts.</i></div>
<div><i><br>
</i></div>
<div><i><b>What do you think?</b><br>
</i></div>
<div><br>
</div>
<div><br>
</div>
<div><br>

<p>Hi!<br>
<br>
Thank you for being on time! :) I watched the video just
now, I think the quality is good overall! I noticed maybe
a few breaks that could be edited out before the final
release, but let's see if the others find it necessary. I
appreciated the figures, and that you point to the words
you talk about.<br>
</p>
<p>So the content is an introduction of the task of
parallelizing the chat server and chat client with some
code examples. <br>
</p>
<p>What's your plan for the students (and instructors) to do
during the class?<br>
<br>
Thanks,<br>

<p>Hi Péter,</p>
<p>Thank you, that would be perfect! I think
the easiest way to share a working copy
internally is to simply upload it as a
file to the Staff team. Each of us already
has access there, and it's very easy to
reupload new versions if needed.</p>
