Four and Twenty Blackbirds

Debut novelist Cherie Priest sets out to update the Southern gothic and although it's a not entirely successful effort, it's definitely an enthusiastic one. Multiracial, cool, gorgeous Eden Moore is a heroine so full of spunk that she verges on the obnoxious at times but, like the novel itself, she possesses a certain undeniable charm. Unlike her literary predecessors, who couldn't manage much more than screams and faints, Eden handles everything with aplomb. From a seeing the dead to a determined, if ineffective, stalker-cousin with murderous intent to revelations of rotting incestuous family roots to an over-the-top supernatural finale set in the middle of a swamp -- Eden can handle it. Priest is most effective as a writer when describing Eden's youthful ghostly encounters with eerie panache, but with sequels in the offing she may stick with Buffyesque supernatural butt-kicking rather than more nuanced chills. She has obvious potential no matter what path she takes. (CFQ Vol. 37, Issue #8) xwidget_63_Four and Twenty Blackbirds

How to change where a symlink points

files is a symbolic link to /media/files/tb-prod/files. When you access files or anything inside it, you'll really access the path under /media. Symbolic links are made and updated using the ln command. This link could have been made with: ln -s /media/files/tb-prod/files files -s means to make a symbolic link. To update a link, either delete the link and create it as above, or use the -f option to ln as well. If you are linking to a folder, you should include the -n option: ln -sfn /a/new/path files This will replace the link with a new one pointing at /a/new/path. The -n option is necessary when linking to a different target folder to avoid creating a sub-folder inside that symbolic link and instead replace the symbolic link completely. e.g. contact@me:/mnt/webdav$ ls a1 a2 a3 a4 a5 a6 contact@me:/mnt/webdav$ ln -sfn /mnt/a2/XYZ a2 contact@me:/mnt/webdav$ ls a1 a2 a3 a4 a5 a6 contact@me:/mnt/webdav$ https://unix.stackexchange.com/questions/151999/how-to-change-where-a-symlink-points

Fix SSL error when install packages using pip

Q : pip install fails with "connection error: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:598)" A : pip install gensim config --global http.sslVerify false Just install any package with the "config --global http.sslVerify false" statement You can ignore SSL errors by setting pypi.org and files.pythonhosted.org as well as the older pypi.python.org as trusted hosts. $ pip install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org <package_name> Note: Sometime during April 2018, the Python Package Index was migrated from pypi.python.org to pypi.org. This means "trusted-host" commands using the old domain no longer work, but you can add both. Permanent Fix Since the release of pip 10.0, you should be able to fix this permanently just by upgrading pip itself: $ pip install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org pip setuptools Or by just reinstalling it to get the latest version: $ curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py (… and then running get-pip.py with the relevant Python interpreter). pip install <otherpackage> should just work after this. If not, then you will need to do more, as explained below. You may want to add the trusted hosts and proxy to your config file. pip.ini (Windows) or pip.conf (unix) [global] trusted-host = pypi.python.org pypi.org files.pythonhosted.org Alternate Solutions (Less secure) Most of the answers could pose a security issue. Two of the workarounds that help in installing most of the python packages with ease would be: Using easy_install: if you are really lazy and don't want to waste much time, use easy_install <package_name>. Note that some packages won't be found or will give small errors. Using Wheel: download the Wheel of the python package and use the pip command pip install wheel_package_name.whl to install the package. https://stackoverflow.com/questions/25981703/pip-install-fails-with-connection-error-ssl-certificate-verify-failed-certi/26062583

Silver Screen

xwidget_62_Silver Screen Anjuli O'Connell has a perfect memory, but no confidence in herself -- knowing, afterall, is not understanding. Roy Croft is undoubtedly brilliant and knows everything -- "how the pieces fit together, and how they don't." They both work for OptiNet, a vast multinational that owns the worldwide communications network and the artificial intelligence, 901. Eccentric Roy, despite his involvement with extremist political groups fighting for AI liberation, is too valuable a programmer not to employ; Anjuli is a top expert in AI psychology. Roy turns up dead and OptiNet is quick to call it suicide. Just before he died, Roy filed against OptiNet with the Court of Human Rights in an effort to prove that 901 is a being in its own right. This is puzzling in itself as he was aware a move like that would doubtless lead to 901's "death" rather than its liberation. He also left a series of cryptic messages for Anjuli that may be luring her into an insanely dangerous game for his own warped purposes or leading her to an important truth. The storyline runs through mystery/thriller territory as Anjuli seeks answers and, finally, a mysterious Source must be found and recovering it requires a solo mission into a super-fortified pseudo-abbey in experimental biomech armor. But that is far from all. Robson's debut novel may be imperfect, but it's astonishingly full of imaginative imagery and stylish writing. First published in the U.K. in 1999 it is belatedly arriving in the U.S. only after two subsequent and even more-accomplished novels. Provocative and unique, Robson is stellar talent of the first magnitude. (CFQ Vol. 37, Issue #8)

20th Century Ghosts

xwidget_61_20th Century Ghosts This may be your first encounter with a writer named Joe Hill, but it most certainly will not be the last. This remarkable, not-to-be-missed debut collection may well herald the beginnings of a notable career. Christopher Golden, in his introduction, refers to Hill's stories as "subtle", but they are more noteworthy for their perfectly eloquent lucidity than understatement. Often laced with nostalgia reminiscent of Bradbury and graced with the irresistible imaginative tug of Stephen King at top form, Hill's stories are more skewed and surreal than either writer's and usually fall further into weird. "The Cape" even lulls you with Bradburyian charms then gleefully skewers you with Kinglike wickedness. Hill also has a knack for reviving the jaded sensibilities of the veteran horror reader. The title tale is a ghost story that delivers the unexpected for those who have read plenty of ghost stories and think they know what to expect. The burned-out editor of an annual anthology discovers an astonishing story and its distressing author in "Best New Horror". The ending may be inevitable, but the tale still entrances. In the accomplished novella, Voluntary Committal, two teenage boys deal with the reality of a terrible accident. Reality may be mutable and memory can be sealed "behind a wall of carefully laid mental bricks," but such a wall may not last forever. In the fabulist "My Father's Mask", a family visits Masquerade House, a place where it's always Halloween, surrounded by a deep dark woods "where grown-ups cannot go." "Pop Art" can be labeled as "magic realism", but it is also a moving yet humorous story about friendship and death. Joe Hill. Read him. (-- First published in Fantasy Magazine #1, November 2005)

Beyond Black

xwidget_60_Beyond Black There's a place between skepticism and belief, between the known and the unknown. You sit there comfortably while you glance over your morning paper and read your horoscope or an article on a "haunted house". It echoes with phrases like "harmless fun," "I don't take it seriously, but..." "of course there's nothing to it," and "my great-grandmother used to say..." It's where hotels build their thirteenth floors and where the coins you toss into wishing wells land. But it is also a disturbing location. The pinch of spilled salt you throw over your left shoulder "just in case" lands there. Paths crossed by black cats and walking routes under ladders might lead you there. It's usually a place of minor trepidations and disregarded terrors, but the gods we fear dwell there, too, and damnations we dread lurk within it. Hilary Mantel's Beyond Black plops you right down into the middle of that place between what you know and what you don't know and has you laughing at irrational absurdities while being chilled by absurd irrationalities. The author makes you laugh and shiver simultaneously. The title could describe her humor -- "beyond black". It is, in fact, so dark that it enlightens. Mantel's characters, even in minor roles, are astonishingly vivid. Vile, charming, cruel, kind, mundane, weird, dead or alive -- they will remain with you longer and more distinctly than some of your blood relations. Alison is a psychic -- "a professional psychic, not some sort of magic act" -- who plies her trade both privately and publicly in the counties surrounding London. It's a lucrative profession, but she experiences almost constant physical and mental anguish due to her life-long dealings with "airside." The dead are a bothersome, nattering lot and her "spirit guide" is a lecherous, vulgar lowlife named Morris. Her childhood was abysmal and lacking in even the slightest of comforts; as an adult she offers an odd, but genuine, comfort to others. Alison is a "woman of unfeasible size...soft as an Edwardian, opulent as a showgirl." When she leaves a room you feel her as "a presence, a trace." And she is in need of both personal and business organization. Colette is thin and so colorless she barely notices herself. "When I'm gone I leave no trace," she thinks. Alison says that when Colette has been gone an hour or two, "I wonder if I have imagined you." She's also efficient: "sharp, rude, and effective." Other than lewd specters, Alison has no real relationships with the opposite gender. Colette is divorced from a man nearly as insipid as she. Since the bland couple had no friends, they invited everyone they knew to their picture-perfect, utterly empty wedding and the marriage was over before the ceremony was paid off. The final push out of matrimony came when Colette phoned and spoke to her mother-in-law -- who she consequently discovered had been dead for a number of hours at the time of the conversation. There's always the chance, she admits, it might have been a wrong number, but her life is so meaningless even the thought she might have communed with the dead gives it meaning and she starts seeking out psychics. It turns out that Colette hasn't a whit of psychic power -- even reading Tarot cards is beyond her -- but she does become Alison's personal assistant/business partner. She gets Alison's affairs in order and her career on the right track. Colette doesn't quite believe in the paranormal, but like most of us she can "entertain simultaneously any number of conflicting opinions." When "[f]aced with the impossible", Colette's mind "simply scuttle[s] off in another direction." Colette learns much of the psychic biz -- Mantel skewers the "Sensitives" with sparkling satire -- is fakery and flimflam. Alison uses such techniques herself, but not to defraud. She smoothes uncomfortable truths and conveys soothing messages to her audiences and clients rather than passing on the lies and confabulations of the perfidious, selfish, trivial, generally clueless dead. Although she doesn't particularly believe, Collette cannot deny Alison's abilities. Colette believes enough to be frightened of the afterlife as Alison paints it: ...the bewildered dead clustered among the dumpsters outside of burger bars, clutching door keys in their hands or queuing with their lunchboxes where the gates of a small factory once stood... There are thousands of them out there, so pathetic and lame-brained they can't cross the road to get where they are going, dithering on the kerbs of new arterial roads and byways... they follow [Alison home], and stat petering the first chance they get. They elbow her in the ribs with questions always questions; but never the right ones. Always, where's my pension book, has the Number 64 gone, are we having a fry-up this morning? Never, am I dead?... Collette also probes and prods Alison with questions in pursuit of material for a book she intends to produce. Dead voices and strange noises play havoc with the recordings of the interviews, but the dialogues also force Alison to begin confronting her past, much of which is unclear to her until Colette forces her to talk about it. Even before we know the entire story it's a past nasty enough to establish a possibility (never voiced by characters or author) that Alison's supernatural abilities might stem from psychosis rather than psychic connection. Spirit guide Morris, in fact, was one of a murderous band of thugs who dominated Alison's unspeakably brutal childhood. As Alison recalls more of her childhood, Morris's dead but still villainous mates seem to be reassembling to further torture her. The women escape the "fiends", as Alison calls them, by moving to a spanking new house in a new upmarket development full of families and minivans. (Realty, new construction, suburbia and its inhabitants are all impaled on the spike of Mantel's sardonic wit.) Despite everyone thinking that Alison is some type of weather forecaster and that the women are a lesbian couple, the move brings Alison temporary respite from the fiends. But Colette, ever more controlling even as she occasionally feels unappreciated, increasingly sees her life as a dead end. No new man has entered her life in the seven years she's spent with Alison. Paying but pointless punters and kooks, Al's fellow Sensitives -- who disdain her as much as she disdains them -- surround her. Her ex, Gavin, tells her he is dating a model. Meanwhile Alison remembers more and more of her dreadful early days and the dead fiends, their fiendishness now even more enhanced, are drawing nigh and bringing death with them. There's more here, too, than a mere narrative. Mantel piles opposites on top of dualities, offers scathingly true observations on modern life, and shapes an overall metaphor for England circa 1997-2004. Surprising, unsettling, deeply subversive -- one cannot but wonder if Mantel's literary cohort will completely appreciate what a dark marvel this novel is. Readers of Peter Straub, Ramsey Campbell, Graham Joyce, and Elizabeth Hand, will, however, recognize Hilary Mantel as beyond brilliant.
