This book is pretty preachy (if you're not a republican your wrong and you're what's wrong with the universe), and long. The story also centers around haunted warships, which is a bit of a leap for this series. On the other hand, its a good read if you can put up with those bits. Overall ok, but not the best in the series.

Watch on the Rhine




ISBN: 9781416521204
LibraryThing
If you knew you were in deep trouble, had the technology to rejuvenate any soldier you wanted, and happened to be a late nineties Germany desperate for cannon fodder, would you return the SS to service? A harsh reality is that they're some of the only soldiers you have left with real combat experience, even if their politics is abhorrent. This book has an interesting underlying concept, but to a certain extent its ruined by the politics of the authors -- any concern for anything other that military strength is dismissed as another example of rampant nimbyism. However, the book tells a good story and made me think about some stuff I wouldn't have otherwise thought about, while being entertaining. So, overall a success I guess.

While it isn't immediately obvious, this book is quite similar to Johnny Mnemonic. The brain damage aspect is played up a bit, and gets repetitive, but the overall story is interesting and fun, even if the ending is a bit obvious from about half way through.

A first pass at glance replication

A few weeks back I was tasked with turning up a new OpenStack region. This region couldn't share anything with existing regions because the plan was to test pre-release versions of OpenStack there, and if we shared something like glance then we would either have to endanger glance for all regions during testing, or not test glance. However, our users already have a favorite set of images uploaded to glance, and I really wanted to make it as easy as possible for them to use the new region -- I wanted all of their images to magically just appear there. What I needed was some form of glance replication.

I'd sat in on the glance replication session at the Folsom OpenStack Design Summit. The NeCTAR use case at the bottom is exactly what I wanted, so its reassuring that other people wanted something like that too. However, no one was working on this feature. So I wrote it. In fact, because of the code review process I wrote it twice, but let's not dwell on that too much.

So, as of change id I7dabbd6671ec75a0052db58312054f611707bdcf there is a very simple replicator script in glance/bin. Its not perfect, and I expect it will need to be extended a bunch, but its a start at least and I'm using it in production now so I am relatively confident its not totally wrong.




The replicator supports the following commands at the moment:

livecopy
glance-replicator livecopy fromserver:port toserver:port

    Load the contents of one glance instance into another.

    fromserver:port: the location of the master glance instance.
    toserver:port:   the location of the slave glance instance.


This is the main meat of the replicator. Take a copy of the fromserver, and dump it onto the toserver. Only images visible to the user running the replicator will be copied if you're using Keystone. Only images active on fromserver are copied across. The copy is done "on-the-wire", so there are no large temporary files on the machine running the replicator to clean up.

dump
glance-replicator dump server:port path

    Dump the contents of a glance instance to local disk.

    server:port: the location of the glance instance.
    path:        a directory on disk to contain the data.


Do the same thing as livecopy, but dump the contents of the glance server to a directory on disk. This includes meta data and image data, and this directory is probably going to be quite large so be prepared.

load
glance-replicator load server:port path

    Load the contents of a local directory into glance.

    server:port: the location of the glance instance.
    path:        a directory on disk containing the data.


Load a directory created by the dump command into a glance server. dump / load was originally written because I had two glance servers who couldn't talk to each other over the network for policy reasons. However, I could dump the data and move it to the destination network out of band. If you had a very large glance installation and were bringing up a new region at the end of a slow link, then this might be something you'd be interested in.

compare
glance-replicator compare fromserver:port toserver:port

    Compare the contents of fromserver with those of toserver.

    fromserver:port: the location of the master glance instance.
    toserver:port:   the location of the slave glance instance.


What would a livecopy do? The compare command will show you the differences between the two servers, so its a bit like a dry run of the replication.

size
glance-replicator size 

    Determine the size of a glance instance if dumped to disk.

    server:port: the location of the glance instance.


The size command will tell you how much disk is going to be used by image data in either a dump or a livecopy. It doesn't however know about redundancy costs with things like swift, so it just gives you the raw number of bytes that would be written to the destination.




The glance replicator is very new code, so I wouldn't be too surprised if there are bugs out there or obvious features that are lacking. For example, there is no support for SSL at the moment. Let me know if you have any comments or encounter problems using the replicator.

Got Something to Say? The LCA 2013 CFP Opens Soon!

The call for presentations opens on 1 June, which is only 11 days away! So if you're thinking of speaking at the conference (a presentation, tutorial, or miniconference), now would be a good time to start thinking about what you're going to say. While you're thinking, please spare a thought for our web team, who are bringing up the entire zookeepr instance so that the CFP will work properly.

We've been getting heaps of stuff done over the past few months. We've had a "ghosts" meeting (a meeting with former LCA directors), found conference and social venues, and are gearing up for the Call For Presentations.

We've signed a contract for the keynote venue, which I think you will all really enjoy. We have also locked in our booking for the lecture theatres, which is now working its way through the ANU process. For social events, we've got a great venue for the penguin dinner, and have shortlisted venues for the speakers' dinner and the professional delegates' networking session. We're taking a bit of extra time here because we want venues that are special, and not just the ones which first came to mind.

The ghosts meeting went really well and I think we learnt some important things. The LCA 2013 team is a bit unusual, because so many of us have been on a LCA core team before, but that gave us a chance to dig into things which deserved more attention and skip over the things which are self-evident. We want to take the opportunity in 2013 to have the most accessible, diverse and technically deep conference that we possibly can, and there was a lot of discussion around those issues. We've also had it drummed into us that communications with delegates is vitally important and you should expect our attempts to communicate to ramp up as the conference approaches.

I'm really excited about the progress we've made so far, and I feel like we're in a really good state right now. As always, please feel free to contact the LCA2013 team at contact@lca2013.linux.org.au if you have any questions.

Catching Fire

This is the second book in the Hunger Games trilogy after the first book of the same name. This book is very similar to the first in terms of style, although I think the start is a lot slower. Once you plow through the first 150 pages or so the book rapidly improves though, and I was happy with where it went overall. Good teen fiction.

Jupiter

This is the first book of Ben Bova's that I've read. Before that I've only read "The Nonmetallic Isaac or It's a Wonderful Life" in Foundation's Friends. I bought this book randomly because I had run out of things to read on a business trip, and I don't regret it. The book is well paced, interesting and fun to read. It also explores alien life in a way which is particularly believable (unlike many other SF books I encounter). This book reminds me of Dragon's Egg without being so hard-SFy. A very good book.

The Hunger Games

I picked this up in the US really cheap because I had run out of books to read on this trip. This book is pretty heavily hyped at the moment, but that's also why I got the book for $6 at a book store, so I can't complain. The book is an easy read, and fun. Its obviously aimed at teenagers, but I don't mind teen fiction as a genre and I read this book in a little over a day. The story line is similar to The Survivor in Battlefields Beyond Tomorrow, but is distinct enough to not be plagiarism. I enjoyed this book.

The Android's Dream

This is a Scalzi book, so its clever and funny, and has possibly one of the best first sentences I have read ever. It is a light read, and I finished all of it apart from the last 50 pages or so on a single flight. Scalzi also plays again with the idea of transferring consciousness, which is something which he deals with a lot in the Old Man's War series. I liked this book.

Logos Run




ISBN: 0441015360
LibraryThing
This is the continuation from Runner, and continues the story of the attempt to re-enable the star gates. It has the comicly incompetent Technosociety once again, as well as series of genetically engineered protagonists. I am bothered by why the star gate power supplies cause people to fall ill -- you'd think in a highly advanced society capable of building star gates they might have spent some time on shielding. Or did the shielding somehow fail on all the power sources sometime over the thousands of years of decay? The has a disappointing ending, but was a fun read until then. I find it hard to suspend disbelief about how the AIs present themselves, but apart from that the book was solid. This one is probably not as good as the first.
