Taught my first Yoga class

Taught my first Yoga class tonight! I taught a group of 16-18 year olds, it was about an hour long class, I showed them the Sun Salutation, twists and a lot of breathing. Wow, it was very cool.

Ahh, I love coding. Check this out:

// Iterate through this list until all clones are in paths
in_paths = contigs[ctgnum]->num_show;
while ((i < tot) && (in_paths > 0)) {
// Look at both clones
inlist1 = check_inlist(bl[i]->indx1,&c);
inlist2 = check_inlist(bl[i]->indx2,&c);
if (inlist1)
endlist1 = check_endlist(bl[i]->indx1,&c);
if (inlist2)
endlist2 = check_endlist(bl[i]->indx2,&c); // If both clones are already in the middle of lists
// - yay! do next one
if ((inlist1 && inlist2) && ((!endlist1) && (!endlist2)))
continue; // If neither clone is in a list
// - make a new list out of these two
if ((!inlist1) && (!inlist2)) {
} // If one of the clones is the end of a list
// - Add other clone to the end of this list
// Do for indx1
if ((!inlist1) && (endlist2)) {
} // Do for indx2
if ((!inlist2) && (endlist1)) {
} // If one of the clones isn't in a list, and other is internal in a list
// - add these clones to appropriate PathItem->link

Latest screenshot of contiger.

Latest screenshot of contiger. Notice the cool marker display below the contigs, with both maximum
extents of marks, as well as the consensus region. Little colored boxes identify the different
markers and are matched with the clones above.

Latest screenshot of contiger. It’s getting cleaner and more featureful all the time. Going to add graphical display of markers next.

Had so much fun out

Had so much fun out tonight with Di, Brian and Heather. Went to a nice Indo-American fusion place, Sami’s and then to
Delilah’s for some wonderful martinis (virgin for me, of course) and conversation! Yay!

Shiva level in Nethack A

Shiva level in Nethack

A portal is generated at around level 10-15 that takes you to the Shiva level. There are 4 levels,
3 are big rooms, but completely filled with really nasty monsters that don’t leave any items. First level is elementals, second is golems, third is demons. Here’s the trick, if you have been a pacifist, all these monsters will instead be figurines of these monsters. The fourth level is empty, except for a throne in the middle of the room. Around the throne are an amulet of life saving, a bag of holding,and two blessed figurines of a Archons, Ida and Pingala.

If you have been a pacifist, Shiva is seated in the middle of the room in meditation, and will give you the “Mantle of Shiva”, which you can wear for huge AC, protection from fire, cold, level
drain and shocking. You can apply it in a direction and all monsters in that direction will be
turned into figurines. You can invoke it, when invoked it summons another high level pet.

Shiva!

More Yoga!

Hee hee, check this out:

//
// Enumerated Mountain Rule
// struct PathList; // One item in a path
struct PathItem {
int indx; // Index into clones[]
struct PathItem *next; // Next PathItem in the list struct PathList *links;
}; // One path
struct PathList {
struct PathItem *head;
struct PathItem *z;
}; // All the paths
struct PathCollection {
struct PathList *head;
struct PathList *z;
};

Hee hee! Lots of recursive data structures here! Isn’t the PathList in PathItem a cute multi-dimensional treat?

Man, I love coding little

Man, I love coding little cute algorithms, I love thinking about the most efficient way to implement algorithms, weird little data structures.. Cool. I find in C that I stick with simpler data structures like arrays, not like how I used to work in C++, but then there is more to keep track of in C, which makes it fun and challenging.

Interesting day today, got a

Interesting day today, got a great start on the Enumerated Mountain Rule, wrote this cute little bit of code:

int compare_sulstons(const void* a, const void* b)
{ if((*(struct MatrixListItem**)a)->score < (*(struct MatrixListItem**)b)->score) return -1;
if((*(struct MatrixListItem**)a)->score > (*(struct MatrixListItem**)b)->score) return 1;
return 0;
}
int build_bestlist(struct Clone **clones, struct Contig **contigs, int ctgnum, int tolerance)
{
int i, j, k;
int num, tot; // 1) Allocate memory for list and clear list
num = contigs[ctgnum]->num_show;
tot = num * (num - 1) / 2;
bestlist = (struct MatrixListItem **) malloc (sizeof (struct MatrixListItem*) * tot); for (i = 0; i < tot; i++) {
bestlist[i] = (struct MatrixListItem *) malloc (sizeof (struct MatrixListItem));
bestlist[i]->indx1 = -1;
bestlist[i]->indx2 = -1;
bestlist[i]->score = 0.0;
} // 2) Build the list (half the matrix)
k = 0;
for (i = 0; i < num; i++)
for (j = i+1; j < num; j++) {
bestlist[k]->indx1 = contigs[ctgnum]->show_indx[i];
bestlist[k]->indx2 = contigs[ctgnum]->show_indx[j];
bestlist[k]->score = sulston(clones[contigs[ctgnum]->show_indx[i]],clones[contigs[ctgnum]->show_indx[j]]);
if (DEBUG >= 2)
printf("Adding %3i %3i %3i\t\t1=%3i\t2=%3i\t%.1e\n",i,j,k,bestlist[k]->indx1,bestlist[k]->indx2,bestlist[k]->score);
k++;
} // 3) Sort this list by sulston score
qsort(bestlist, tot, sizeof(struct MatrixListItem*), compare_sulstons);

// 4) Print the list out
if (DEBUG)
for (i = 0; i < tot; i++) {
printf("Score = %.1e\ti = %i\tClone A %3i (%s)\tClone B %3i (%s)\n",bestlist[i]->score,i,
bestlist[i]->indx1, clones[bestlist[i]->indx1]->clonename,
bestlist[i]->indx2, clones[bestlist[i]->indx2]->clonename);
}
return tot;
}

Isn’t that cute? :)

Wow! More fun work today!

Wow! More fun work today! Pulled out all the code from ,gactg and put it into ga.c and ga.h, then made gactg just call these routines to do it’s work. Then, used ga.[ch] to add gactg functionality to contiger! So, now you can look at your contigs, and interactively run
genetic algorithms on them to fix them up. Hopefully will put this right into FPC which would rock, but might be difficult. I’ll get it going in contiger first, then go crazy after that.

Did a little redesign on

Wow, had an incredible week!

Wow, had an incredible week! Wrote over 1500 lines of code, got a
full GA up and running that looks very promising for doing our contig
ordering!

This takes 15 seconds to run at home (600 MHz Pentium III) for 10000
generations. Order is perfect, except that 8 should be at the leftmost
end.

Scores are all the sulston exponents between each neighbour and the next.
This tries to minimize that quantity. It’s very fast.

Cool, eh!

Saw SNFU this weekend. <a “href=http://www.snfu.com/photos/chi1.html”>Chi Pig</a> is just as hardcore as ever. Also, you know
it’s a good punk concert when somebody is carried out, head bandaged, on a stretcher.

At the request of Simon I’m posting in my blog again. :)
I’ve been working on programs to order fingerprinted contigs in the Mouse map, and have been
SUPER busy. More updates soon, I promise.
