★★★★☆ Easy Network-attached storage

Western Digital My Cloud Ex4100 network-attached storage

Western Digital My Cloud Ex2100 network-attached storage

In 2015 I bought a Lenovo Thinkserver. I installed a linux OS, and I bought four 4 TB hard disks and installed them. In 2015 4 TB was a big disk. I configured them as two RAID1 arrays, giving me 8 TB of two-fold redundant hard disk storage. I thought at the time that was a lot.

I use that system directly, and also as a network fileserver for Windows machines. Recntly the disks started to fill up. To fix that problem I bought a Western Digital My Cloud 2100 diskless network-attached server . I put two 8 TB disks I had lying around into it. (Yes, I keep spare hard disks at home -- doesn't everyone?). I configured them as a two-fold redundant array. That gives me an 8 TB network disk. If one of the physical disks breaks, the network disk will continue to function while I replace the broken disk. Note that this is not the same as backup. In my experience the main use of backups is when you discover that you just stupidly deleted that presentation you've been working on for two months. The RAID1 redundancy doesn't help with that -- it just saves you from hardware failures.

I was so happy with this that I bought a Western Digital My Cloud 4100 diskless network-attached server and put four 16 TB disks in it, configured as two redundant arrays. That gave me two 16 TB network disks.

I have not used any other brand of NAS, so I can't compare. I am, however, quite happy with these systems. Under the hood these are linux system, like the one I set up on my Thinkserver, but optimized to be used as file servers. You can't really use one for programming, etc. But as file servers they are quite nice. SATA hard disks just snap in. You needn't use WD disks -- all mine at the moment are Seagate, and they work fine. There is an easy to use web interface for configuring the disks. Each device also has three USB 3.0 receptcles. You can plug an external USB disk into any one of these and back the My Cloud disk up on it. Also, any external disk plugged into any of the USB ports is shared automatically as a network drive, which is very handy.

In most respects the 4100 is like the 2100. The main difference, of course, is that the 4100 has four hard disk bays and the 2100 just two. Also, the 4100 is taller and has an LED display that you can use to find out handy things such as the IP address and free space left.

It is relevant that I have been administering unix and linux systems for thirty years. I know what I'm doing, and it helps. Someone without *nix experience could figure it out, but it might not be trivial.

★★★☆☆ There was never going to be an HEA

Warrior Diplomat: A Green Beret's Battles from Washington to Afghanistan Michael G. Waltz I picked up Michael G. Waltz 's Warrior Diplomat: A Green Beret's Battles from Washington to Afghanistan because President-Elect Donald Trump nominated him for National Security Advisor. I saw that he had written this book and read it to get an idea of who he is. First lesson: Waltz is not a buffoon like Matt Gaetz or Robert Kennedy, Jr. "Not a buffoon" is a low bar, but with this administration a nominee who clears it is welcome. In fact, I would go so far as to say that Waltz is an intelligent man with serious experience relevant to the post of National Security. If you are more than 30 years old, you have probably had this experience. You know a couple -- perhaps one of them is a friend of yours. Their relationship is always on the rocks. They fight, and the fights are serious. Because you're outside the relationship, you can see what neither of the principals

★★★★☆ Fictional autobiography of Rome's fourth Emperor

I, Claudius Robert Graves Robert Graves 's I, Claudius begins with these words I, Tiberius Claudius Drusus Nero Germanicus this-that-and-the-other (for I shall not trouble you yet with all my titles), who was once, and not so long ago either, known to my friends and relatives and associates as ‘Claudius the Idiot’, or ‘That Claudius’, or ‘Claudius the Stammerer’, or ‘Clau-Clau-Claudius’, or at best as ‘Poor Uncle Claudius’, am now about to write this strange history of my life... It is ostensibly an autobiography written by Claudius himself, covering the years of his life until he suddenly and unexpectedly became Emperor of Rome. (The sequel, Claudius the God continues the story into his reign.) Claudius is an intelligent and, given his environment and predecessors, surprisingly decent and humble man. Of course, the reader never forgets that we have only Claudius's own word for who and what he is. But his intelligence is beyond doubt -- a fool could not have written this. P

★★★☆☆ Peggy Carter sans Steve Rogers

Agent Carter Christopher Markus, Stephen McFeely, Marvel Near the end of Captain America: The First Avenger Steve Rogers dives his airplane into the sea in order to prevent it from reaching (and destroying) New York City. In a final radio conversation with Agent Peggy Carter, he makes a date to take her dancing next Saturday. Both of them know he will not make that date. Agent Carter shows Peggy Carter's career after Steve's fall and after the end of the Second World War. The year is 1946, and she is an agent with the Strategic Scientific Reserve, a fictional secret organization that was the precursor to S.H.I.E.L.D. It is, I suspect, more or less based on the OSS , which was more or less the precursor to the CIA. Although she is one of SSR's most experienced and effective operatives, having had experience in the SOE (a real English spy operation in World War II) before coming to the American side, Peggy is relegated to fetching coffee and answering phones by her bosses

★★★☆☆ Succession in Djelibeybi and other stuff

Pyramids Terry Pratchett Yesterday I finished listening to Terry Pratchett 's Pyramids (book 7 in his Discworld series, and I find myself doing what I usually do when I finish a Discworld novel: scrambling frantically to locate the plot. It's not that Pyramids lacks a plot. My problem is Pratchett 's everything-up-to-and-including-the-kitchen-sink approach to story-telling. The plot of Pyramids is surrounded my yards and yards of stuff that seemed like a good idea at the time. And indeed, most of those things were good ideas. I'm influenced by my background. I have written many scientific papers. My approach to writing a paper is to identify one main conclusion that I want to convince the reader of, then require that every sentence marshall evidence for or against that conclusion. Fiction is different, but not SO different as all that. The corresponding idea in fiction is that every sentence should advance the plot. Now, of course this is not a universal rul

★★★☆☆ Minimal surreal magic school story

Midnight for Charlie Bone Jenny Nimmo Charlie Bone has one friend, who has a dog. Charlie lives with his mother and two grandmothers, one who is kind (Maisie) and one, Grandma Bone, who is severe. Charlie discovers unexpectedly that he has a gift -- he is "endowed", as Grandma Bone says. When he looks at a photograph, he can hear the conversation that took place when it was taken. Grandma Bone tells him that, because he is endowed, he must go to a special private school, Bloor's Academy. Charlie accordingly goes to Bloor's Academy, meets other endowed children, and has adventures. Although this sounds like Harry Potter or Percy Jackson , the feeling is completely different. Jenny Nimmo 's style is spare to the point of minimalism. Nothing is described in more than the barest outline. I don't have a mental image of any of the characters. The story is told in the third person from Charlie's point of view. His inner dialog is minimal. I don't have a f

★★★☆☆ Informative but annoyingly tendentious

Pathogenesis: A History of the World in Eight Plagues Jonathan Kennedy There is a book that everyone who is interested in biology and history should read: William H. McNeill 's Plagues and Peoples , published in 1976. I suppose that is long enough ago that we are allowed to call it a classic. Plagues and Peoples is an example of what I call a "I have a new hammer -- look at all these nails!" book. McNeill 's new hammer was consideration of the effects of infectious disease on history. He argued that infectious disease was an important force in history, persuasively in my opinion. Jonathan Kennedy 's Pathogenesis: A History of the World in Eight Plagues intends to update McNeill . Kennedy points out quite correctly that the advances in technology since 1976 enable us to see more deeply and clearly into the past of infectious disease than McNeill possibly could and thus to replace much of McNeill 's speculation with clearer and more solid answers.

★★★★★ Cornelia Funke still gots it

Die Farbe der Rache Cornelia Funke I first listened to Cornelia Funke 's Inkworld trilogy (as it then was) beginning in 2004, and then as the audiobooks became available. They were among the very first audiobooks I ever listened to, and they were VERY good. The premise of the series is that some especially good narrators can, by reading a book aloud, read characters from the fictional world of the book into our own, and likewise read people from our world into the fictional world of the book. Versions of this idea are fairly common in fantasy fiction, and it's not hard to see why. If you are an avid reader, you feel that something like this happens when you read a good book: you enter into the book, and for a while you dwell in that fictional world. Aside from our own, the world in which most of the action of the Inkworld trilogy takes place is one created by a writer named Fenoglio in a fantasy novel called Inkheart . Although the series begins in our world, the principa

★★★★☆ Worst possible time to become a physician

Eleanore of Avignon Elizabeth DeLozier Elizabeth DeLozier 's Eleanore of Avignon is a story of the Black Death in Avignon, Provence, France. Even aside from the plague, there was a lot going on in Provence in 1348. It was that strange period in the history of the Roman Catholic Church when it was not literally Roman -- the popes lived in Avignon , not to be confused with the later even stranger period when there were simultaneously two guys claiming to be the pope. Clement VI was pope. His physician Guy de Chauliac (Guigo) would later became famous for an influential book on surgery, Chirurgia Magna . To make life even more exciting, the pregnant Queen Johanna of Naples arrived in Avignon while the plague was raging to be tried for the murder of one of her husbands. All of this really happened. In 1347 our hero, Eleanore Blanchet (an entirely fictional character), an herbalist and midwife living with her twin sister and father, runs into Guigo and manages to persuade

★★★★☆ If Virginia Hall was fictional, she would not be believable

A Woman of No Importance Sonia Purnell Fiction writers operate under certain constraints. Their characters and plots have to be believable. Pile the implausible too high, and critics and readers will complain. ( Mea culpa .) Reality is not thus constrained. Thus, Virginia Hall, an American spy, a tall striking redhead who speaks French with an American accent, and has a wooden leg that she calls Cuthbert, who organizes Resistance forces in occupied France during the Second World War, and who assembles and leads a force of about 1000 Maquis (rural guerillas) that defeat the Germans and drive them out of Le Puy before the Allied invasion reaches it. (Cuthbert seems so gratuitous. I would shout to the heavens about a fictional spy with a wooden leg. But Virginia was real, and she really had a wooden leg, and she really called it Cuthbert.) And this is only one of Hall's exploits. Before that she was the Limping Lady of Lyon and the Abwehr and Gestapo were obsessed with her, but never

★★★★☆ A broken mindship and lost children

In the Shadow of the Ship Aliette de Bodard Aliette de Bodard 's In the Shadow of the Ship is a novella set in her Xuya Universe . Like many Xuya stories, this one takes place aboard a mindship. This particular mindship is called Nightjar and was damaged escaping from the collapsing Empire. (Exactly which Empire this was I am not sure -- there is more than one in the Xuya Universe .) At any rate, Nightjar is not a healthy place. She escaped carrying some of her family. They still live aboard and afford her the loyalty she expects, mostly. Nightjar demands tribute in the form of children whom she lures into her dead zones, from which they never emerge. When Khuyên was a child she was invited to the dead zones by her cousin Anh, but she refused. Later she did the unthinkable: she left Nightjar for the broken Empire, where she rose to the post of Magistrate. Now Khuyên has returned to Nightjar for her grandmother's funeral, where she is met with a complex mixture of disdain
