Cybermancy (WebMage 02)
by Kelly McCullough

Description:
Hades has a hell of a firewall in this WebMage novel from Kelly McCullough.

Not just any computer geek can hack into Hades. But Ravirn, a direct descendant of one of the three Fates, is no ordinary hacker. Magic has gone digital in the twenty-first century, and Ravirn is a sorcerer with a laptop—otherwise known as his shape-changing best friend.

These days, Ravirn’s crashing at his girlfriend’s place while she works on her doctorate in computer science. Only one problem: all of her research is in her webgoblin’s memory, which is now in Hades along with its soul. To save Cerice’s webgoblin (and her PhD), Ravirn must brave Hell itself. But can he do it without corrupting the mweb—the magical internet—and without facing down the Lord of the Dead himself?

Review:

This review will have minor spoilers about the first book because what events from the first book have significant bearing on the second book as it build on top of them. If you haven’t yet read the first book, stop reading.

At the end of the First book free will is saved, Ravirn is still alive but renamed as Raven and no longer part of the Fate’s family. Throughout this book he is still trying to come to terms with the changes in his life and pretend that the Raven side of him doesn’t exist. The book starts off with an awesome sentence “Who says you can’t teach an old dog new tricks ? The eyes of Cerberus glared down at me, six balls of black fire. There was no dog older or more dangerous. But here I was standing practically in his mouths, trick in hand.” and then takes off from there.

Ravirn is trying to retrieve the soul of his girlfriend’s webgoblin from Hades and in doing so unleashes a massive problem for the whole of reality. He is frantically trying to fix the issue while the major powers of the universe are out baying for his head making life a lot more interesting for him. Over the course of the novel he starts accepting his Raven side more as well.

The book is a fun read and I loved the way it covers the story of Persephone. According to mythology, Hades, god of the Underworld, fell in love with beautiful Persephone when he saw her picking flowers one day in a meadow. The god then carried her off in his chariot to live with him in the dark Underworld. Her mother Demeter created a great drought to convince the other gods to release Persephone from Hades. Finally after lots of people died Zeus finally sent Hermes to persuade Hades to release his ill-gotten bride. But Hades had tricked Persephone into eating pomegranate seed so had to spend three months of the year in Hades. Its a very stark tale but most books/tales gloss over how it must be for Persephone to live with Hades for 3 months every year after he had kidnapped and raped her. Persephone’s anger & despair are covered beautifully and with compassion in the book, it really highlights what victims of sexual violence have to deal with throughout their life.

The consequences of the events of this book are explored in the next few books so I ended up rereading the 3rd book immediately after I finished this one.

Happy 20th Birthday Nokia 3310!

Filed under: My Thoughts — Suramya @ 8:51 PM

The Nokia 3310 was launched on 1st Sept 2000 and is a legendary phone. Known for being nearly indestructible it helped accelerate the Mobile phone trend, with around 120 million devices sold during its lifespan. Both me and Surabhi had this phone and I have personal experience of its near indestructibility, Surabhi once took the phone on a roller coaster and midway through the phone fell out from her pocket (don’t ask me why she had the phone in the pocket as I don’t know). We assumed that the phone was a total loss and that we would have to get a new one. When the ride ended, we searched for the phone pieces and reassembled them. To all of our surprise the phone immediately booted up without any problems. There was a small crack on the battery panel but the phone worked without issues for another couple of years. Compare this to my S8 which had a cracked rear panel after falling from the bed.


The legendary Nokia 3310

“The Nokia 3310 is a true icon in the mobile phone world. Having sold over 120 million units its ubiquity meant that it is a device that many people owned, often as their first mobile phone. This means it generates a real sense of nostalgia which further underlines its status as one of the most important mobile phones of all time.

“The robust design made it almost indestructible in daily use and its ease of use meant that it became a firm favourite with customers. It is little surprise the design was rebooted in 2017 by HMD Global, the company that now licenses the Nokia brand for phones.”

The most recent 3310 version apes the aesthetic of the original well, although ditches some of its simplicity for a bevy of modern accoutrements, including a colour display and a 2MP rear camera.

I love my Samsung S10 but really miss the durability of the old cellphones.

Background radiation causes Integrity issues in Quantum Computers

Filed under: Computer Related,My Thoughts,Quantum Computing,Tech Related — Suramya @ 11:16 PM

As if Quantum Computing didn’t have enough issues preventing it from being a workable solution already, new research at MIT has found that ionizing radiation from environmental radioactive materials and cosmic rays can and does interfere with the integrity of quantum computers. The research has been published in Nature: Impact of ionizing radiation on superconducting qubit coherence.

Quantum computers are super powerful because their basic building blocks qubit (quantum bit) is able to simultaneously exist as 0 or 1 (Yes, it makes no sense which is why Eisenstein called it ‘spooky action at a distance’) allowing it process a magnitude more operations in parallel than the regular computing systems. Unfortunately it appears that these qubits are highly sensitive to their environment and even minor levels of radiation emitted by trace elements in concrete walls and cosmic rays can cause them to loose coherence corrupting the calculation/data, this is called decoherence. The longer we can avoid decoherence the more powerful/capable the quantum computer. We have made significant improvements in this over the past two decades, from maintaining it for less than one nanosecond in 1999 to around 200 microseconds today for the best-performing devices.

As per the study, the effect is serious enough to limit the performance to just a few milliseconds which is something we are expected to achieve in the next few years. The only way currently known to avoid this issue is to shield the computer which means putting these computers underground and surrounding it with a 2 ton wall of lead. Another possibility is to use something like a counter-wave of radiation to cancel the incoming radiation similar to how we do noise-canceling. But that is something which doesn’t exist today and will require significant technological breakthrough before it is feasible.

“Cosmic ray radiation is hard to get rid of,” Formaggio says. “It’s very penetrating, and goes right through everything like a jet stream. If you go underground, that gets less and less. It’s probably not necessary to build quantum computers deep underground, like neutrino experiments, but maybe deep basement facilities could probably get qubits operating at improved levels.”

“If we want to build an industry, we’d likely prefer to mitigate the effects of radiation above ground,” Oliver says. “We can think about designing qubits in a way that makes them ‘rad-hard,’ and less sensitive to quasiparticles, or design traps for quasiparticles so that even if they’re constantly being generated by radiation, they can flow away from the qubit. So it’s definitely not game-over, it’s just the next layer of the onion we need to address.”

Quantum Computing is a fascinating field but it really messes with your mind. So I am happy there are folks out there spending time trying to figure out how to get this amazing invention working and reliable enough to replace our existing Bit based computers.

Description:

Magic is about to get an upgrade

Ravirn is not your average computer geek. A child of the Fates – literally – he’s a hacker extraordinaire who can zero in on the fatal flaw in any program. Now that twenty-first-century magic has gone digital that makes him a very talented sorcerer. But a world of problems is about to be downloaded on Ravirn – who’s just trying to pass his college midterms. Great Aunt Atropos, one of the three Fates, decides that humans having free will is really overrated and plans to rid herself of the annoyance – by coding a spell into the Fate Core, the server that rules destiny. As a hacker, Ravirn is a big believer in free will, and when he not only refuses to debug her spell but actively opposes her, all hell breaks loose.Even with the help of his familiar Melchior, a sexy sorceress (who-s also a mean programmer), and the webgoblin underground, it’s going to be a close call…

Review:

There are some books that you don’t mind reading again and again, this is one such book. I was reminded of the book by the last book that I read (Hardwired) so I picked it up again. I think this is the 3rd or 4th time that I have read the book. The main character is a WebMage, which is basically a Hacker/programmer who uses programming to write control magic spells. The story is fast paced and is a light reading in the sense that you don’t need to spend much brain power while reading the book.

The characterization of the Fury’s was brilliant and in quite a contrast to the traditional portrayal of the characters where they are usually depicted with a serious deminor or just plain focused. Over here they are denoted with a sense of humor (dark humor but still funny) and each of them have a different personality. The book utilizes sarcasm and witty dialog to great effect. The character of Cerice could have used more screen time and is lightly developed in this book but that is addressed in the next book so its not a major complaint.

The Book is setting up the stage for the rest of the series so a lot of the setup is either not utilized or lightly utilized as they are explored/expanded in the remainder of the series.

Final Review: I love the book and highly recommend it.
