 * 0			tagged queuing disabled
 * 1 <= n <= 253	n == max tags ever dispatched.
 *
 * The driver will throttle the number of commands dispatched to a
 * device if it returns queue full.  For devices with a fixed maximum
 * queue depth, the driver will eventually determine this depth and
 * lock it in (a console message is printed to indicate that a lock
 * has occurred).  On some devices, queue full is returned for a temporary
 * resource shortage.  These devices will return queue full at varying
 * depths.  The driver will throttle back when the queue fulls occur and
 * attempt to slowly increase the depth over time as the device recovers
 * from the resource shortage.
 *
 * In this example, the first line will disable tagged queueing for all
 * the devices on the first probed aic7xxx adapter.
 *
 * The second line enables tagged queueing with 4 commands/LUN for IDs
 * (0, 2-11, 13-15), disables tagged queueing for ID 12, and tells the
 * driver to attempt to use up to 64 tags for ID 1.
 *
 * The third line is the same as the first line.
 *
 * The fourth line disables tagged queueing for devices 0 and 3.  It
 * enables tagged queueing for the other IDs, with 16 commands/LUN
 * for IDs 1 and 4, 127 commands/LUN for ID 8, and 4 commands/LUN for
 * IDs 2, 5-7, and 9-15.

THE STORYKEEPERS PROJECT #9: FRENCH IMMERSION
BRIT ANDERSON for THE STORYKEEPERS PROJECT
It is often difficult to understand the motivations of previous generations. For example, looking through a family lineage, surnames are not always fixed from one generation to another, changing for a variety of reasons. The same can be said for identity. Here is a story about re-embracing French Canadian identity in Ontario and, through an immersion program, choosing French as the language of daily life.––ed
My family was always a confusing bunch. My father was the oldest of six kids, so I had a good number of cousins. We knew that my grandfather, my father's dad, was French Canadian, and that for whatever reason, he'd changed his last name. We knew he couldn't speak a word of English when he came to Ontario from Granby, Quebec, and that Granny had taught him English.
Grandpa always loved to play with his children, and later his grandchildren. He always liked to take us all out for ice cream, and since there were so many of us, we rode in the pick up truck, a bunch of kids back in the cargo-compartment – it was always a lot of fun! Sometimes we'd go out for ice cream many times in a day. Our parents knew exactly what we were doing, but pretended not to know.
He liked to break into the freezer and find Granny's cookies and eat them with his kids back when my Dad was growing up. On my Dad's birthday one year, before I was born, my Grandpa and my brother found one of his boxes of chocolates and decided they'd have "just one each", but by the end there was none left!
He did a lot of work with wood and made us a lot of toys. He once made me a beanie babies holder out of wood for all my beanie babies, and he made me a toy truck out of wood, since I loved to play with cars. He made my brother a bird house and me a toy sword out of wood. He was a very playful, funny man.
But he never discussed the past. He wouldn't speak French, and he wouldn't tell us anything about our family history. My father did not pursue French growing up since his dad would not help him with his homework. My father knew he had French Canadian heritage, but culturally he was English Canadian.
My mother, who is English Canadian herself without a drop of French Canadian blood, insisted to my father that her children would be in the French immersion programs in school. My father did not see much point, but since she insisted, we went into the French immersion schools as young children. She wanted us to be bilingual.
I started out in Montessori school, and learned French at school since I was two years old. Then I had a tutor just before French immersion school (grade 1) began so I could get ahead. When I was in French Immersion I excelled, and French became my normal, and in fact, my preferred language. I'm unique in my family that way.
The other kids in the family (cousins) went to English school, while we went to French immersion, my brother and I. But my brother dropped out and switched to English and doesn't use French anymore, while for me it's still my preferred language. I identify as a Francophone because of this; for example even in English, I stubbornly put the dollar sign at the end of the number as we do in French! I don't know why Grandpa tried to quit being French Canadian, but I know that French Canadian is just who I am because of my upbringing and it's something I won't quit.

I am sure you are aware of the appeal below to help Mr Paradan to undergo a kidney transplant. I am delighted to inform you that the boy had underwent kidney transplant in Colombo on 13 Dec 2016 and now residing in a rented house in Colombo in order to attend follow ups. He is recovering well and will be going to Vavuniya after a month. I attach a couple of photos: one was taken in the hospital; other after he was discharged.
Diaspora from the UK, Singapore and Malaysia (FOMSO) as well as kind hearted people in Sri Lanka donated generously and saved Mr Paradan's life. On behalf of Mr Paradan and Assist RR, I would like to express my gratitude to all those who made donations (please see table below) and made this happen .
I attach the bills and provide the breakdown of the costs and the donations received. As you can see, we couldn't raise the full amount needed for the surgery. Assist RR (SL) and Engineer Sriskandarajah have provided loans to settle the hospital bill. It is anticipated that Mr Paradan may receive some contribution from the President's fund. In this case, the loans will be repaid using this contribution. If not, Assist RR will raise the necessary funds to settle the two loans.
I would like thank again for your kind support.
Subject: Re: A boy desperately need assistance towards a kidney transplant – Can we help?
Ganeshamoorthy Parathan aged 20 from Ganeshapuram, Vavuniya, has been diagnosed with chronic kidney disease and has reached End stage renal failure. His only hope of survival is renal transplant therapy. His parents have found a match for a kidney donation from a man who lost both of his legs during the war. However, they require financial assistance to carry out the transplant in Colombo. Could you please kindly consider this appeal and contribute so that this young man can survive from his decease? Mr Parathan's family lives below the poverty line and have no chances of funding the treatment themselves. If he doesn't receive the transplant, he has no hope of survival. If we can contribute even a little, this young man can be helped.
Assist RR was approached by kind hearted individuals from UK seeking assistance to raise funds to help this boy. Several documents related to his medical condition were given to us and are attached to this email. His condition has been independently verified by Assist RR (Sri Lanka) and we can confirm that he needs our help for his survival. Assist RR has therefore agreed to support this effort and has set up a fund raising page, which is given below. Please consider helping him and share this with your friends and family as well.
Mr Parathan's family lives below the poverty line and have no chances of funding the treatment themselves. If he doesn't receive the transplant, he has no hope of survival. If many Diaspora Tamils contribute even a little, this young man can be helped.
Sri Subramaniyam Vidyalayam Primary school in Puthukudiyiruppu was completely destroyed at the end of the war and was functioning in temporary shelters.

La Reserva índia del Riu Moapa és una reserva índia situada al nord-est de Las Vegas, vora Moapa Town. és la terra de la banda Moapa dels indis paiute, una banda local dels amerindis dels Estats Units paiute del sud. La reserva del Riu Moapa consta de 71.954 acres (29.119 hectares).

En l'any 2000, la població era de 206 habitants, dels quals el 80,1% eren amerindis.

Localització i geografia
La reserva és creuada de nord-est a sud-oest per l'autopista I-15. Al sud-est, es troba al costat del Parc Estatal Valley of Fire. En particular, la sortida 75 de l'autopista i la carretera local que condueix a l'entrada del parc a l'oest (abans Nevada 169, donada de baixa en 2001), davant de l'entrada, pertanyen a la reserva.

Here is a list of the rabbit rescues that we know of in Berkshire.
RSPCA Reading Rabbits – Working alongside Reading & Oxon RSPCA, we provide temporary and permanent care for rabbits, finding new homes for unwanted and stray pets. We rely on donations and volunteer help with the care for these rabbits.
Diana Brimblecombe Animal Rescue Centre – Based in Hurst, nr Wokingham, The DIANA BRIMBLECOMBE ANIMAL RESCUE CENTRE formerly the Animal Rescue Group, Wokingham, was founded over 40 years ago. For a large part of that time animals rescued by the Charity were kept at the home of Mrs Brimblecombe, who was awarded the MBE in 2001 for services to Animal Rescue.
Rabbit Rescue Reading – Based in Reading, I aim to offer all the rabbits that come into my care a safe and happy home until they are adopted in to a loving new family. I am responsible for housing the rabbits, feeding them a good diet of hay, mixed vegetables and dried food as well as looking after any medical needs that may arise.

The extended Star Trek cast and crew — from the original series in the 1960s to the 21st-century movie reboot — are mourning the actor, who died early Sunday.
Anton Yelchin, an actor most famous for playing Chekov in the rebooted Star Trek series, was found dead Sunday after he was crushed by his own car.
This is how the Star Trek cast and crew — from the original TV series in the 1960s to the 21st-century movie reboots — have remembered the 27-year-old star.
J.J. Abrams, director of the Star Trek reboots, said Yelchin was "funny as hell, and supremely talented," in a hand-written note that he shared on Twitter.
"our dear friend. our comrade. our anton. one of the most open and intellectually curious people i have ever had the pleasure to know. so enormously talented and generous of heart. wise beyond his years. and gone before his time. all love and strength to his family at this impossible time of grief."
George Takei, most famous playing Sulu in the original 1960s series, said the "Star Trek family has lost one of its own."
John Cho, who plays Sulu in the new films, also shared his grief on Twitter.
Please send your love to Anton's family right now. They need it.
LeVar Burton, known for his role of Lieutenant Commander Geordi La Forge in the Star Trek: The Next Generation TV series, was in disbelief.
Karl Urban, who plays Leonard "Bones" McCoy in the reboot movies, was also struggling to comprehend the loss.
Jonathan Frakes, who played Commander William T. Riker in The Next Generation, described Yelchin as a "family member gone too soon."
Yelchin died after being struck by his own car in a freak accident at his Los Angeles home.
"His family requests you respect their privacy at this time," his publicist, Jennifer Allen, told BuzzFeed News.
This post will be updated as more Star Trek cast and crew react to Yelchin's death.
