With mascarpone, blueberry and lingonberry preserves, a huge fresh ginger root, cloves, nutmeg, almonds, whole wheat flour, flax seed, applesauce, milk and baking soda for the leavening.



Even though I added a good sized ginger root chunk, it's not spicy. Next time, I will probably add even more. I purposefully mixed the doughly roughly so that I would get the hard crusty exterior and the bread would be slightly crispy. I don't particularly like moist bread. They don't toast too well. Unfortunately, it wasn't dry enough because in spite of all these precautions it's rather moist. Maybe I should have waited for it to cool down instead of slicing through it like the hungry, impatient and greedy person that I totally am.

I finally found it. I don't know what took me so long. But this is amazingly effective.


Baking Soda
(1 pinch/sprinkle)

+

Coconut oil
(to dissolve/make a paste from the baking soda)


You can substitute the coconut oil with vaseline intensive care or perfume-free vaseline. It will work just as well. Apply liberally on odor-prone underarm areas. That's it. No more chemicals or plastic packaging waste or even dehydrating alcohol derivatives ever.

I just sprinkle some baking soda on my palm, mix with a spot of coconut oil and apply immediately after showering. It works so well that I now have trouble finding out what clothes I have worn and what clothes I haven't if I don't consciously toss them in the laundry bag. I would say it has eliminated around 99.8% odor.

Try it out, if you haven't already.

LastFM just sprang this on me and I was completely blown away!

Coding is time consuming. I didn't really consciously think about this till my advisor asked me about the roadblocks to my progress in my dissertation. I thought back and it occurred to me that I was

• learning a somewhat new language (R)
• trying to code in it using concepts from statistics that I already have
• trying to generalize code so that it could be less repetitive and automate chores and processing
• trying to splice other languages such as latex and perl to interact with R code
• learning THOSE other languages
• trying to prevent errors in their interaction
• trying to write functions that would serve a purpose similar to "macros" on SAS but yet be understandable to me at a somewhat-novice level.
• debugging to see where it all goes wrong when errors turn up
• differentiating what is my code's fault, what can be changed in R preferences, and what is inherently the fault of the R build on the particular linux distro I am using.

Why am I doing this when I have a data manager for the data I am dealing with? Because it's insane to go whining to the manager the minute you want some data processing done. He has own Ph.D. to complete and has limited time and innumerable demands. So there is really no option but to power through all of this on my own. Besides, I think population sciences are *really* about statistics and data processing even though population scientists who don't do all this dirty work may persuade themselves that it is just about interpretation. It is as much about quality control in the data and seemingly trivial logical checks as it is about analyzing super-clean data in the end and figuring out what it could mean in the bigger picture of million other studies. I think it's important to acquire this skill so I can use it in my future. Not everyone has a data manager, a software coding bloke and a statistician to always help them.

The process itself is exhausting because it's like learning a completely new language without having ANY experience in how the semantics work. Apparently some people have observed this exhaustion and set up sites like "Software Carpentry": It sets up a formalized framework within which you could learn these skills. I think courses like this should be mandatory to population sciences coursework. At some point, we need to realize that population sciences and bioinformatics are very similar in their scope and application. This is more true than ever as we progress rapidly towards HUGE datasets, complex data structures, multidimensional variables and the necessity of channeling all of this into interpretations simple enough to make sense to health-related and population policy-making.

I am very close to a complete Fridge wipeout.
I currently have
- A wonderful big Cauliflower {needs to be used this weekend}
- 2 frozen bananas
- 1 ripe tomato {priority use this weekend}
- 1 orange
- 1/4th lb okra {super priority use maybe tomorrow}
- Ginger
- Garlic
- Some hot chillies

Well.. maybe not that close but still this is a reflection of workload. I think I might reach the wipout this weekend and give the fridge a scrubdown before I go grocery shopping.

Found a nice solution to the crazy external monitor problem in Fedora 15:
Download the latest release of ARandR from here:
Extract to some directory and navigate to that directory:

cd /arandr-0.1.5/

Run arandr.

./arandr

All external display problems SOLVED! Woohoo. Thank you, Christian Amsuess. You simply rock. I saw they are trying to get this nifty program reviewed to include it in the Fedora yum repository For such a wonderful program that replaces the crap they have in gnome 3, the brutal review process seems somewhat counterproductive.

---

The Extended monitor display works. However, if I assign the external monitor as the primary display, it doesn't work. It gives me a blank backlit screen. WHYYYY?

I really need one of these counters now.

The number matches. I have the exact expression too.

In addition, I feel like I could outshout the incredible hulk anytime after /var/log/messages records an exception that could have well read, "You wouldn't like me when I'm angry normal".

There's something really wrong with my setup here:

Even though there is now a driver in use (installed from here: ) I still cannot adjust my resolution. I didn't install nVidia's own driver because of this article:

There is only ONE resolution in the display settings (1024X768). Attaching an external monitor results in the computer shutting down on its own. And there is no way to adjust brightness.

Aarrgh. Frustration ++. I am just going to ignore this today. I have too much work piled up.

Getting information about package versions from Yum

• yum info packagename

Side note to @paul: R does pull in the following dependencies:

texlive.x86_64 0:2007-62.fc15
texlive-dvips.x86_64 0:2007-62.fc15
texlive-latex.x86_64 0:2007-62.fc15

texlive-texmf-latex.noarch 0:2007-37.fc15
texlive-utils.x86_64 0:2007-62.fc15

It's such a pity the packages it pulls are from 2007! :/

And Gnumeric doesn't even start up now. Something about:

gnumeric: symbol lookup error: /usr/lib64/libspreadsheet-1.10.17.so: undefined symbol: go_direction_get_name

• In Debian, you can actually, copy the entire /var/apt/cache files into a new installation and have the apt manager pull the .deb files from there without having to download packages over and over. But I don't see any such package repository in Fedora in the /var/cache/yum/ directory. It's all rolled into some sort of a database file. I found from this link that yum *deletes* everything after install. This is kind of wasteful for people who have enough space but not enough bandwidth(ME!). To prevent yum from deleting all the packages after install, apparently, I need to make keepcache=1 in /etc/yum.conf Now I only need to remember this detail next time.

• These are my detailed specs just for reference...

Sometimes the simplicity of things across all distributions of linux are most refreshing. To burn an iso into a USB and create a bootable USB, I was glad to find out that I didn't need to hunt for programs as I usually do. I could do it in 4 steps.

---

@paul would like to remind everyone that this method completely gets rid of all the existing data on the USB drive so do it on an expendable one not somewhere you have all your backup files.

---

Pull up a terminal.
Pull up the system messages by

tail -f /var/log/messages

This records the realtime happenings on your system

Plug in your USB, you'll see it coming up on the messages window
Let's say its /dev/sdb

---

At this point @uncutsaniflush would like to say:
You should also note that this only works if your usb drive is "/dev/sdb." If a box has multiple hard drives, it is unlikely that "/dev/sdb" would be your usb drive. If someone had for example two hard drives, "dev/sdb" would be the second one. And thus, all data on the second hard drive would be destroyed. "dd" is a wonderful tool but rather easy to misuse if one isn't absolutely clear which drive is which.

---

On the terminal again, umount it first

umount /dev/sdb

Go to the directory containing the iso image

cd /directory/that/contains/iso

Then give the simple command to burn the iso into the USB

dd if=file.iso of=/dev/sdb

This will take a while to finish, but yes, it's that simple.
