If there is one thing that error messages in /var/log/messages are really good for it is for regular expressions practice. I think I am getting better at regex by using the regex tool in geany to sort out and condense the list of errors my system encounters almost daily. I don't know what most of these errors mean but I gather than anything that has "error|warning|failed" is a problem.

I am realizing that the error messages are organized and labeled pretty well. I was able to isolate all the problematic messages from different components of the system with some regexing, sorting, deletion of duplicate lines and numbers within brackets. I guess the numbers within brackets are IDs of sorts but I am just focusing on the unique errors for now. I whittled down the list of 933 lines to around 100. It would have been nice if I could get the count of how many times the error occurred right next to the error line, but I haven't figured out how to do that yet. Some of these errors/failures/warnings occur numerous times; some as many as 100 times.

Hmm.. so basically, everytime I want to connect to a wifi hotspot, the system has this error: Activation (wlan0) failed for access point (ESSID of hotspot) Googling for this error brings up an enormous number of threads, for eg. This is definitely a problem with the kernel module for my wireless card. I guess whoever made that module must not have tested it on multiple-point wireless access spots or where hotspot signals are weak. It does connect comfortably with a single access wireless spot at home. Kind of defeats the mobility of the laptop. Wish the people who made the kernel module would revisit the module in less than ideal wireless scenarios and do some bug-fixing because I am way in over my head trying to troubleshoot this. I tried (e:uncutsaniflush)'s suggestion of trying other kernels. Every kernel that I tried and that has a wireless module for my card pretty much has similar problems. So no luck there.

All this drama makes me conclude that the biggest thing that linux has going against it is hardware support. There is no dearth of software genius in the community.

Text Processing Tools:
Apart from regexing, I found TextOpus online I wish I could write perl programs that replicate the functionality of this tool. Or just download an offline version of the tool.

Actually I just want to be as skilled as Tomasz Klekot at text processing.

I think I have the magic ratio, finally.

1: Water
+ 2.00 ~2.25: Whole Wheat Flour
≥ 0.25: Ground Flax Seed {I think this is where you can add "whatever"}
+ 1 Tbsp: Fig butter
+ 2 Tbsp: Extra Virgin Olive Oil
+ generous salt
+ ~1/2 packet yeast



Let the yeast feast on
1:Water
1:Flour,
1tbsp olive oil
generous salt and the fig butter. (they like fig butter! It's basically food for the yeast. I couldn't taste it in the bread probably because the yeast ate it all.)

The feasting period ends with a warmish bubbly looking liquidy flour. Add the rest of the flour and extras and knead till your arms fall off the dough is not sticky but slightly tacky. Use the rest of the oil while kneading the dough.

Let the dough rest for 2-3 hours. (Up to 12 hours if you want to intensify the sour taste. I didn't have any patience today and allowed just 2 hours before I harvested the dough for the next phase.)

Punch it down, knead, shape and put in loaf pans.
Cover the loaf pan with an aluminium foil tent as a lid.
Put it in the oven. Let it sit for 30 more minutes.
Turn on the oven and set the temperature to 350-375 deg F.
Bake the loaf covered for around 30 minutes
Uncover, spray the bread with water and bake for 20~30 more minutes.

Let the bread cool (gluttons will be tempted to slice whiles it's still hot. I did! The result is super delicious but the bread is kind of wet and doughy with the water vapour and not like what you would expect from bread).

Slice after cooling. Spread speculoos paste or butter generously on slices and Enjoy!

Mission 5 accomplished! *

PS: The pizza I made alongside this bread was an unmitigated disaster. The less said about it the better.

Why does every corner shop and big retailer want me to "like" them on facebook?? It's so annoying especially when they link offers and discounts to this asinine practice.

I want those offers, dammit. But I don't want facebook. I won't get those offers and discounts if I don't submit to the lameness and sheep-herding on facebook.

Hmm...

I guess my resistance against facebook trumps my attraction to those offers.

I am glad it took so little time to get this quandary sorted.

PS: Where did the drawing gadget on (e:strip) go?

0. R completely and thoroughly
1. Perl well
2. Unix commands well (so commandline becomes second nature)
3. to churn out papers like a maniac (aka postdoc)
4. how to make perfect stovetop popcorn
5. how to make a perfect sourdough bread every single time
6. how to make perfect pancakes or waffles
7. how to make pizza base without a recipe and well.

I intend to get a head start on those resolutions.

181,456 X $13 (out of which McD's get $6.50) and counting.

I am tempted to get those 5 large fries.

EDIT
Whoa. They extended the deal by a day. And 20K more people have been caught in the fly fry trap. That is almost approaching the size of the whole population of Buffalo.


And damn, I totally missed out the $10 Whole Foods deal! I need to check my spam folder more often. :)
