Installed JAL on a new computer. I did basically the same as yesterday and it still did not work. At the end what was missing was to remove the NB. from the line in configure unzip ... NB. some text ... after the unzip in the config. After that it started to work. I probably did remove that yesterday also without thinking about it.

Thank you for reporting your experience with installing JAL. It is valueable for improving PacMan's heuristics in future versions. --- Bj�rn Helgason <[EMAIL PROTECTED]> wrote: > I was going to look at dendrite and your examples but ran into the same > problems of being without JAL so I finally gave in and tried to install JAL > > Got the libraries and got the run/ pacage manager option straight away. > > Found wget quickly and installed it. > Had some problem finding a site to download and install unzip > Once both wget and unzip where installed and working I was still getting the > report on HTTP Cmd and Unzip > By the way wget was working but the report said always both wget and unzip > not working > > Anyway after wget and unzip were there and working - I was still getting > report from J configure it was not - > I needed to point configure at the web browser - mozilla in my case - and > then it started working - looks like it anyway. > > Now JAL seems to be up and running at this place. > I can not test it further until next week and in the meantime I will also > try to install JAL and possibly some of the addons in other places I have > computers I work on. > > 2007/3/16, Björn Helgason <[EMAIL PROTECTED]>: > > > > That looks really interesting. > > I am pretty sure this can be useful. > > " Outliers are atypical (by definition), infrequent observations" > > I have to admit that I do not understand the technique yet but I will > > certainly give it a try. > > > > Also I have found after going through some hundreds of images that some > > methods are more reliable than others and using only those who are more > > reliable and combine it with this I will be getting pretty close to > > certainty I guess. > > > > I have tried different sizes of the kern 8 8;16 16;20 20; 24 24 - the > > total image being 512 512. > > It looks like 24 24 is giving me best results.
