The performance evaluation vs Hadoop looks bogus to me. S3, SQS and SimpleDB run on real (non-virtualized) hardware. You need a lot more Hadoop nodes to make it comparable. At least throughput per AWS dollar should be reported. The ~100k fi

This is a common practice for corporations, where you need to keep the meeting minutes as part of legal requirements of being a corp (c or s). You (as a Secretary of the corporation) can do it yourself or you can let them do it for you for

Most of these "high-level" languages are more of "extensions" (CLOS certainly feels like an extension) or alternative lispish languages than bona fide DSLs with DS constraints (that can be used for DS optimizations). The S-expression syntax

Risking being downmodded, I'd say Lisp is too "low level" for many common problems, which is great if your domain is parser/compiler construction/transformation/combination. I have no problem with lisp syntax (I can even tolerate C++ templa

The problem is that despite the patent system, "trade secrets" remain and increasingly so in SaaS. Patents are mainly used as a weapon to impede the progress of competitors. Abolish software patents, now!

Maybe my comment was not clear enough: buffering writes in memory on a single node alone has no durability to speak of. You need either a DFS or distributed DB that does replication of the buffers on different nodes to provide some reasonab

by vicaya 17y ago
It's generally true for traditional DBs, a few new generation DBs have options to buffer writes in memory and achieve durability via in memory replication in other nodes and only writes to disk sequentially in large chunks, which is better

Structural typing has been around for a while. Ocaml is a prime example.

I've used a 2nd generation Macbook Pro that costs my employer close to $3000 (4GB RAM, 2.4GHz, 160GB HD) for 2 years, during which time the graphic card (Nvidia 9600M GT) died twice (screen suddenly went blank); battery died once (could not

The home page touts "safety" as a feature the language but all it takes to crash the program is concurrent access to the builtin map: "uncontrolled map access can crash the program", according the faq. Interesting so far besides some syntax

Actually many NoSQL DBs are not just about relaxing ACID requirements, but also about limiting functionality for easier scaling via DHT. They only support key/value set/get and not range scan, which is needed to implement SQL semantics. I t

Unlikely. Michael spoke before a small group of people less than a month ago, when I asked about CrunchPad. He said that it's coming along and that "Atom sucks." So, he's probably waiting for Chrome OS running on the new ARM processor (Cort

All the traffic to/from your home is monitored. Encrypted data in the cloud is much safer and more available.

Native storage query language implies using native i.e., non-standardized query language and API. It's an categorical acronym like AJAX.

The stats are misleading, as it's not a comparable rewrite. The new code is refactored and much cleaner. For example, for "LAN Resolver 105 vs 427" a 75% saving. I looked at the actual code (thanks for posting it.) The C++ code contains a l

Any benchmarks compared with Thrift and Protobuf? BTW, Hadoop's new Avro project is yet another serialization project that's designed to be dynamic language friendly. I personally find thrift IDL trivial to manage and is probably the only s

by vicaya 17y ago
Well, although the syntax/idiom is different, the design pattern is the same the Observer pattern. IMHO, design patterns transcend language idioms and enable people to understand/communicate higher level abstraction.

Yeah, I'd like to upgrade my brain with more and faster memory as well.

That's a fine reason, as long as you don't care about being friendly for integration/customization/embedding with external sources.

You're guessing the implementation here. It's only a bad idea if you're doing it wrong :) The source/conceptual tables can be normalized, while the join views can be materialized/implemented with Bigtable like sparse columns, which are dyna

DHT can certainly support range queries by broadcast and merge. The keyword in the context though is efficiently . Scalaris not a typical Dynamo like DHT. It's based on Chord, so it's possible support range scan with O(logn) metadata RPCs

by vicaya 17y ago
Denormalization can happen automatically based on the usage of queries with joins. Some commercial RDBMS like DB2 already do that. SQL is a declarative language. It doesn't force you to use a particular implementation.
