Learning in the bus

Today when I was in the bus, a girl close to me was reading, she had a small block of cards, the cards had a hole in one side and a key ring attached together, simple and effective mode to keep the notes, the notes are some chemical formulas, the amino acids charts, one side was the formula, in the reverse of the card was the name, 3 letter abbreviation and the polar class.

Yes, I remember when in college I learned all this information, also I build some molecules with my atomic-kit, to see the structure, and now I just see the ACGT codes, missing the 3D beauty.

Amino Acid Short Abbrev. Side chain Polar pH
Alanine A Ala -CH3 - -
Cysteine C Cys -CH2SH - acidic
Aspartic acid D Asp -CH2COOH X acidic
Glutamic acid E Glu -CH2CH2COOH X acidic
Phenylalanine F Phe -CH2C6H5 - -
Glycine G Gly -H - -
Histidine H His -CH2-C3H3N2 X weak basic
Isoleucine I Ile -CH(CH3)CH2CH3 - -
Lysine K Lys -(CH2)4NH2 X basic
Leucine L Leu -CH2CH(CH3)2 - -
Methionine M Met -CH2CH2SCH3 - -
Asparagine N Asn -CH2CONH2 X -
Pyrrolysine O Pyl


Proline P Pro -CH2CH2CH2- - -
Glutamine Q Gln -CH2CH2CONH2 X -
Arginine R Arg -(CH2)3NH-C(NH)NH2 X strongly basic
Serine S Ser -CH2OH X -
Threonine T Thr -CH(OH)CH3 X weak acidic
Selenocysteine U Sec -CH2SeH - -
Valine V Val -CH(CH3)2 - -
Tryptophan W Trp -CH2C8H6N - -
Tyrosine Y Tyr -CH2-C6H4OH X -

Ubuntu Cluster - Slave nodes

In this part we'll install and configure the other nodes, in the master node we have a DHCP server and a PXE network boot which serves the netboot system, so we just need to connect the net cable, a keyboard and a monitor to the node, turn on and wait to install the base system. Options include partition of the hda disk, we use the defaults and put all the system in a partition and default swap size. We add the general user named beagle and after rebooting, login, become root, change the password and install the SSH server: sudo su - passwd apt-get install openssh-server Repeat this for all the nodes. The next steps will be only from the master node. SSH access You need to create a pair of keys for each user to access any node without a password, first we create it in the general user beagle : ssh-keygen cp .ssh/id_pub .ssh/authorized_keys Root also need this keys, but we don't export the root's home, after you created the keys, you need to copy to all the nodes.

PS3 cluster

Image
So do you have some PS3 and you're boring of play and watch Blue-Ray movies? You must know the PS3 is the most accessible CELL- based machine, why not use this computer problem in other areas beyond entrainment . In this PS3 ClusterGuide you can build step-by-step your own cluster with PS3, the receipt: 1. Take some PS3. 2. Interconnect it in a LAN. 3. Install Fedora PPC in each one. 4. Install cluster utils . 5. Learn to code in CELL- SDK for a better experience and performance . I accept some PS3 for scientific probes ... really I just want one to play ...
