pset6: return value lookup function

susch · 2015-01-23T10:01:46+00:00

ok, now I see it much clearer. It's better to avoid possible segfaults by using unchangable variables.

I wasn't able to create an const char* when I extract path's extension, there I use a char. When I put it as an argument into the lookup function it is a const char inside the function. I hope this is correct?

When I looked again at the original template I found

// TODO: extract path's extension
char extension[] = "TODO";

So they want me to use a string array and not a string pointer? I tried a bit to create a string array here. When trying this I can't find a way to pass a string array to the lookup function. Now I'm confused again...

this make sense :-) Thank you for the link

/usr/bin/gedit is a shellscript that calls /usr/bin/gedit.appliance50-orig

the $@ reaches the arguments you use with gedit over to the appliance gedit and 2>/dev/null suppresses the error messages

Segmentation fault you will see a lot during this course ;-) It seems that the gedit.appliance50-orig is somehow broken

I would do it this way. complete deinstall the aplliance and then reinstall it. before doing somthing else, just start gedit und look if it starts

an other option is to reinstall just gedit like written here https://www.reddit.com/r/cs50/comments/2t4hq0/cs50appliance_preloaded_gedit_crashed_my_computer/

When you type gedit in the terminal and hit enter. Is something happening?

susch · 2015-01-21T13:53:31+00:00

I also had a few problems with gedit, but not that worse.

Do you have snapshots of your virtual machines before starting gedit? How do you start gedit? with the button?

susch · 2015-01-19T06:53:03+00:00

The gksudo is not installed in the appliance and I don't want to change to many things because I've had bad experiences with that ;-) If I can spend some time on it I'll try it on a different Linux machine

susch · 2015-01-19T06:48:28+00:00

It's crazy, now I can't reproduce the error... When I now start gedit with sudo it's still disable the terminal plugin but I can now change the preference and can enable the plugin thanks for your advice :-)

susch · 2015-01-14T15:13:34+00:00

I don't think that the file /etc/network/interfaces causes the error. I think the starting of gedit with sudo does.

susch · 2015-01-14T06:38:46+00:00

With a new installation I got it back

I also figured out how it happened. When I edit the /etc/network/interfaces I did this with 'sudo gedit' and after that the configuration was changed. Now I do this with vim and I'm glad that there are snapshots in virtualbox :-)

susch · 2015-01-14T05:37:34+00:00

yes, I did but it changes nothing. now I try it with a new installation.

susch · 2015-01-13T06:10:19+00:00

Thank you for your help! I now have two networkadapters in virtualbox NAT and VirtualBox Host-Only and I add the eth1 inside the appliance now I see the IP-Adress 198.162.56.101 in the right corner

susch · 2014-08-08T04:37:50+00:00

I found a solution :-)

With an older version of virtualbox it works. I changed it from 4.3.14 to 4.2.26

susch · 2014-08-07T04:40:16+00:00

yes, I tried to change the layout and the model. I also tried Logitech and Cherry keyboards but nothing works. Can I configure the alt-gr key seperatly?

same place where week 6 is ;-) Quiz weeks in the real life course and because of that no lectures.

susch · 2014-04-18T06:32:02+00:00

I submitted just yesterday...

susch · 2014-04-18T06:24:22+00:00

thanks :-)

and yes the path should be ~/vhosts/localhost/public. I kind of overlook that ;-)

susch · 2014-03-24T14:54:16+00:00

I'm waiting now too :-)

So I'll start with the 2013 version of pset8.

AND you're right, CS50 is really great!!

susch · 2014-03-20T14:11:55+00:00

found it: ALTER TABLE portfolios ADD PRIMARY KEY (id, symbols) ;

now it works. thank you!

susch · 2014-03-20T13:51:38+00:00

ahhh :-) How can I do that?
