Ditto. For me, the 20 minute investment in a post-lunch nap pays back manyfold in increased productivity (to say nothing of health and general well-being) for the rest of the day. Finding a place to nap in an office an environment can be tr

Thanks for the link. This ia a great resource I hadn't encountered before. It's true that some sites provide some sort of status blog or dashboard -- more, I now see, than I'd realized. However, most of them provide very little information

Agreed: the Scalyr page is very much a work in progress, and the presentation leaves much to be desired. Look for improvements in the fairly near future. Thanks for the feedback!

Yes, it's not a panacea. But it's a heck of a lot easier to store a generic supply of printer feedstock, than to store one (or more) of every part that might conceivably break. Suppose that you expect 1% of all replaceable parts to break ov

Seems to me that if this proves out, and can be made affordably, the most exciting application would be electric cars -- no more range penalty vs. gasoline. Anyone know enough to comment on the likely applicability?

0MQ looks very interesting, but most of the information available seems to be "how to use it". I can't find detailed specifications of its behavior, nor a detailed description of the implementation that I could use to figure that out myself

From the article, one problem is that even if you don't use your AWS account on the Amazon store, you could , and so XSS vulnerabilities in the store can be used to hijack AWS accounts. Unfortunately the store is large and complex and so h

LSMs support ordered access. The implementation performs an ordered scan on each .sst and merges the results.

I wish they had done a benchmark of mixed reads and writes. LSMs have some nice properties, but read performance in the presence of writes may not be as good as when there are no writes. With no write traffic, you wind up with only a sing

For me, growing up in Ann Arbor, Border's was the locally owned, independent bookstore. Then one day in the 90s, living in Palo Alto, I read that a local, independent movie theater (the Varsity) was closing down to make room for -- wait

It's great to see a real-world writeup of cross-platform development using HTML5. One question: I tried the app on Android, and it looks pretty much identical to the web version, so -- success. However, the animations seem very slow and c

Multipart uploads only sort-of address this. For one thing, the minimum "part" size is 5MB, so you can only resume at 5MB boundaries (or whatever part size you use). You also have to manage more state yourself.

While the article doesn't answer this, it does explain how they manage to run a database on AWS without depending on EBS: their database isn't hosted by Amazon at all. "...the exact types of data that would have potentially been disabled b

Thanks for the links. The statistics on latency distribution are quite impressive, to say the least. Why do you say that stratified b-trees don't need Bloom filters? Yes, the improved merging discipline reduces the number of arrays to rea

This sounds, in many ways, very similar to the data structure underlying Google's Bigtable ( http://labs.google.com/papers/bigtable.html ) and its descendants. Multi-version key/value store, data organized into a hierarchy of generations,

Yes, the Android emulator is quite slow. I generally find it much better to test on an actual Android device. With the standard Eclipse-based tools, at least, the build + push to phone + launch cycle is fast enough to be quite usable for

No, the scenario you describe could not occur -- it would involve a consistency violation within entity group A. Once you see the effects of write W to entity group A, all operations on entity group A (across all servers) are guaranteed to

To clarify: the HRD sacrifies some consistency, but the sacrifice is limited. It still maintains consistency within an "entity group", using the Paxos algorithm for distributed consensus. Consistency is sacrificed only for queries that sp

Right -- when I said "any service that accepts JSON input", I meant "any JVM-based service that accepts JSON input". I thought the JVM qualification would be clear from the context of this thread, apologies if it wasn't.

Because JSON can include floating-point numbers. If you pass { foo: 2.2250738585072012e-308 } to any JSON service, I'd expect it to invoke Double.parseDouble(...) as part of its input processing, and trip over the bug. This would probably
