Testing a Homeplug-Powerline Network


DlinkI’ve had some wireless issues for quite some time now. There are dead spots in the house – a central wall has metal ducts and a gas fireplace, which are beside the laundry room with its metal-enclosed washer and dryer. About 5-6m of metal interfere with the wireless signal. The modem is attached to the cable, which comes through the north side of the house, and there are no other active cable outlets in other rooms (there are outlets for cable, but they’ve never been properly connected).

Plus the ducts and pies in the basement and the metal front door interfere with the signal out of doors, making it difficult to get good reception in a large portion of the yard – including our favourite summer sitting location; the newly rebuilt front deck.

 

And just to confound matters, my Acer Aspire laptop has the annoying habit of losing its internet connection – while all my other wireless devices are fine – although it can see other networks nearby and even connect to my modem. Just not the net.

I’ve looked at all sorts of solutions, from wireless extenders and bridge routers, to rewiring a large portion of the house to accommodate moving the cabling to allow the modem to be placed closer to the laptop. I’ve moved the modem a few times, but the reception has only improved indoors – out of doors it remains unstable.

There is often a 10-metre ethernet cable running across the floor between laptop and modem when I want to be sure my access isn’t interrupted. Susan hates it. It’s a trip hazard and looks hokey.

This week I decided to try a different approach (a suggestion from Neville on Facebook): a powerline (aka homeplug) network extender. It’s a whole area I knew nothing about before this week, except for the vague understanding that the network connects via the AC power lines in your home.

Basically you plug one adapter into a wall socket and attach it to your modem via a (shorter) ethernet cable. They you plug in a second adapter somewhere else in your house, preferably close to your computer, do whatever the device needs to establish a connection (in my case, push a button). When they connect, you plug another (shorter) cable into the adapter and your computer.

But which one? Which type, which standard, which brand, which feature set? That’s what I spent most of my past few days studying. Reading reviews, technical papers, speed tests, manufacturers’ claims. Prices range from $40 to almost $150 for the minimal two adapters. Why the difference and would it really matter to me?

In the end I went low-end rather than cutting-edge. I bought a D-Link “PowerLine AV 500 Network Starter Kit (DHP-309AV) from the local Staples store. Took all of two minutes to set it up, another minute to connect cables and my laptop was connected to the internet.

And if it proves itself in the upcoming months, I may look at the new models due out this fall to upgrade to the new AV2 standard, and get some extra ethernet ports strung around the house.

Chasing storms on Saturn


There’s a beautiful video about the Cassini mission and its images of the storms on Saturn at the New York Times website. It’s amazing to see what images and information science has given us about a planet 886 billion miles (1.4 billion kms) away and its odd collection of rings and 60 moons.

Saturn’s storms

Saturn takes 30 years to orbit the Sun and in January, 2014, began its first spring in 15 years. Until then, the northern hemisphere was shrouded in darkness and the rings tilted away from us. Now the north pole is in sunlight and the magnificent, monstrously large, hexagonal storm at its centre is clearly visible. The video makes it quite an entertaining and awe-inspiring sight.

The hexagonal shape, while unusual, is natural and has been replicated in the laboratory. It is not, as some wingnut conspiracy theorists suggest, a supernatural event, anything to do with aliens or the gates of hell (nor, as uber wingnut David Icke has suggested, is Saturn a giant, artificial broadcasting device… ).

Cassini will be travelling right over the north pole in 2016 in its final – and perhaps most spectacular – mission, for a close-up view of the storm. You can read more about the weird hexagonal storm on the JPL website. The eye of the storm alone in 1,240 miles across (2,000 kms) and the dorm itself is estimated at 60 miles (100kms) deep.

Cassini took seven years to reach Saturn, but that’s a short time compared to New Horizons, which will reach Pluto next July, after a voyage of nine years.

In related news, the spacecraft Rosetta arrived at the comet 67P/Churyumov-Gerasimenko last week, the first spacecraft to rendezvous with a comet. The images sent back so far have been breathtaking. Rosetta is in orbit 62 miles (100 kms) from the comet, but will soon lower to 31 miles (50kms) to prepare for a landing. Rosetta took ten years to reach its target.

All of this is truly exciting, inspirational stuff, isn’t it? Science never ceases to amaze and astound me.

The Strange World of E-Writers


Pulp magazinesThere’s always been a place for amateur or new writers to present their efforts and hope to see print: publications where you could submit your work and hope the editors found it good enough to print in an upcoming issue. That’s how some famous writers got their start, in the pulp magazines of the 1930s and 40s: Robert Howard, Edgar Rice Burroughs, Isaac Asimov and many more. But all of these depended on getting past the gatekeeper, someone like John Campbell: an editor who set standards – slim as they may sometimes be – and wrangled clumsy prose into shape for publication.

And then there have been self-publishing houses that can eschew the editor and simply print your book as you submit it – as long as you paid the bill to do so. This type of publishing house is still operating and plays an important role in getting many local and personal or family books into print. Many authors, frustrated at not being able to find a national publisher, has resorted to self-publishing. The wonderful book of local oral history, Butchers, Bakers and Building the Lakers used this method to get into print.*

Self-publishing runs the gamut from quality books like this to family genealogies, first novels and collections of atrociously sappy poems. It’s not simply self-printing: it’s self-editing, self-layout and self-design (unless you hire a professional to do it for you – there’s still a role for freelance editors and designers). Still, it has a respectable place in the history of publishing.

I remember in the 1950s and 60s there were ads in magazines for poetry books – submit your poem and an amount of money and you would get back a book of poems by aspiring writers like yourself, the printing paid for by the collective authors. No editor, just a compositor and printer. And usually awful stuff between the covers. But who cared about the rest if you saw your name in print?

Then came the internet and a new venue for self publishing: the website. And from that sprang the blog. But most of these efforts have been limited in scope and size. Almost no one reads a novel online, and would-be authors have had to either break their work into smaller parts or bundle it into a downloadable file for offline printing and reading. With the dwindling public attention span, it’s hard to get readers to stick around a website to read even something as long and rambling as these blog posts, let alone a whole book.

The Net also gave a boost to fan fiction because it allowed fans to collectivize and publish online. Like many other forms of writing, fan fiction has a long history. I remember many years ago, in the 70s, writing fantasy short stories in the world created by Fritz Leiber in his Fafhrd and the Grey Mouser series. Never saw print, mind you, but it’s interesting and entertaining to work within the universe created by another writer – and great practice for the wannabe novelist.

In a similar vein, the original Dungeons and Dragons gamified a fantasy universe for players to both participate in and develop their own, personal story lines – some of which led to fan books and magazine stories.

Now, with the arrival of e-readers, those authors have a new platform, a new audience, and what a world it has spawned.

E-readers: worth the investment?


BookshelfI have a passionate, somewhat obsessive, relationship with books. Real books: paper, ink and glue. Not digital books. I have a lot of books and I treasure each one like an old friend. I love reading – I read books at least an hour every day, and usually much more. The feel of a book in my hands is a comfort and a delight.

I worked in book publishing – a dream job for anyone with a passion for reading.

I’ve never been seduced by an e-reader – even though at heart I’m a techie geek who likes hardware and gadgets almost as much as books. E-readers always seemed to cater to the pop-fiction crowd and I don’t read much contemporary fiction (mostly non-fiction: science, history, politics fill my shelves). However, I do read fiction: mostly the classics.

I also resist buying a digital book if I can’t share it, can’t keep it on a shelf to re-open later, can’t write my name on the inside, can’t clip it into a pocket or a knapsack. I like to have a small, unruly stack of books beside my bed so I can read chapters from several titles before I sleep. And books on the dining room table. Books on the toilet tank lid. Books on the floor. On the coffee table beside the couch.

An e-reader just seems so tidy.

But I suppose it’s not really very different from buying a computer game or DLC on Steam or buying vehicles on World of Tanks (which I’ve done without any philosophical pondering). They’re digital downloads, too, not actual purchases, like e-books.
