It's not an entirely new art form. The demoscene [0] has been going strong far longer than most of us have even been coding. So apparently some people _will_ execute interactive art. Also, you can still listen to their music on soundcl

Speaking for myself: Berlin has a special kind of poor-is-sexy culture and this would not be too unusual. Lived there for 4yrs, most of them without a smartphone (had a 20eur burner phone for communication and to receive monitoring alerts).

Yes, but this is only a solution if your library is only targeting windows. If you want users of any standards-compliant C++ implementation to be able to use your library today, you'll still have to go with c-abi symbols or ship the so

Thanks. I had read that article some time back :) Sadly it does not give a figure/order of magnitude of the amount of data that's stored in citus after aggregation, but I guess it's just not public information. [I'm work

by paulasmuth 10y ago
Impressive. Any chance you could tell how much data is stored for the analytics service after pre-aggregation? (In terms of TB/day or so - I guess it can't be the full 70gbit/s?).

Actually, you can even have incompatibilities with the same compiler and different compile flags. So to reliably build a "semi-portable" c++ object one would have to ensure that all objects are compiled with the exact same (i.e. s

by paulasmuth 10y ago
That's almost 70gbit/s (are those cloudflare http logs by any chance?) on 100 nodes vs ~170mbit/s on 6 nodes. Or, in other terms 700mbit/s per host with your kafka setup versus ~30mbit/s per host in the benchmark. A

This confused me, too. I think what they meant with "1000 nodes" is that the dataset they're using for the benchmark is synthetic monitoring data (where the thing being monitored are servers). And the way they generated the s

Just so sad that Vertica is proprietary so we can't see how they did it! ;) On a serious note: Please check out EventQL [0] some time. It's very similar to Vertica in some ways and completely open-source. It's a new project (

Yes, the delta encoding scheme you described (and other fancy coding schemes such as bitpacking, varints, RLE or a combination thereof) are frequently employed in columnar storage formats and databases. Columnar storage is basically a gener

The linked article is an obviously bullshit benchmark that makes influxdb look good and cassandra look bad (by, surprise, the influxdb folks). I'm far from a cassandra fanboy, but this really is just dishonest marketing. Not sure if th

It seems to solve a different usecase. LLVM is (by their own documentation) not really intended for ad-hoc JIT compilation for queries. It doesn't put a lot of priority on making the compilation fast (but rather makes the produced code

None of these numbers add up. If 30 million hours were watched with an average bandwidth of 2Mbps, the total data volume should be 25,749TB (or close to 26PB) and not 400TB. Also, if the peak bandwidth was 600Gpbs, that peak could not have
