I have to admit I don't really understand what this is. Looking at the source I can find and a small server programm that sends/receives hardcoded UDP+JSON messages that contain some very specific data (a few numeric parameters, I

I realize that. I was joking [more like trying to, it seems] about the fact that parent commented on a technically amazing post with "I could have done this too in X" without providing any further insight, let alone a link to the

Yes, this seems like a bunch of work to keep up and running and I agree that most of the meat of their solution is actually in Google's or Amazon's systems running the GeoDNS/push stuff. Hopefully IPv6 will fix it all ™. Howe

The load balancing they describe in their article is only used for inbound requests, similar to a traditional HTTP LB setup. If I understand it correctly they don't implement the outgoing message delivery to the called user themselves,

I was under the impression that asm.js/emscripten are the new hotness these days? Hence not requiring porting everything to JS manually to bring it "to the web" anymore.

That's hilarious -- in fact the full quote is even better. This guy hits it right on the nose: jeff atwood: "any application that can be written in JavaScript, will eventually be written in JavaScript. Writing Photoshop, Word, or

Amazing. Maybe we are onto a new kind of Rule 34 here... "Everything that can be implemented in {c++ templates, javascript} will eventually be implemented in that language"

Pics or it didn't happen ;) /jk On a serious note: modern C++ does have const expression functions, too, albeit not as powerful (yet): http://www.cprogramming.com/c++11/c++11-compile-time-process...

I am not sure if I should be amazed or scared by this. Guess it won't be long before somebody comes up with the only thing left to do, going full meta and writing a "c++ to c++ templates compiler" (or something along those li

Thanks for the clarification! I understand that you got rid of the "trampoline"/dispatch code for calling methods by rewriting the respective bytecode at runtime. But you still need to register file descriptors and such with

Yeah, esp. love the "Would you possibly need a logo design later?" part of your questionnaire. That seems incredibly relevant to choosing a good name for a company. (Not intending to troll you though, hats off to a clever lead gen

I am not convinced this isn't some kind of innovative lead generation method or an ingenious scheme to collect lots of juicy juicy business ideas. Could at least put your name on there so people know who they're dealing with ;)

Thanks for the very interesting article. One thing I didn't find very clear from the paper was the rationale of using a framework/kitsune/all that wrapper code vs just implementing the feature natively. In other words, what i

To answer my own question here, but without being a java expert, so talking out of ignorance probably. This paper [1] argues there are only two methods to do this on the stock JVM. One is putting in some trampoline code, the other one is pa

by paulasmuth 11y ago
Honest question; How can you even do this (replace the running binary/java code without closing file descriptors, etc) in plain java/on the jvm? [ Without resorting to tricks where there is some trampoline code that actually does

I love this! Now all we need is some higher level DRAW operations (draw a line from here to there, draw a piece of rendered text here) and we can glue PixQL and ChartSQL together to implement SQL query result visualization to bitmaps comple

I think that was parent's point. Coming from other languages, it's kind of unexpected that a var defined within a curly brace block (if/for/etc) is actually scoped on the whole function in which it appears and not just t

Any chance you could expand on some of those pains? Is the problem with simply sharing the data itself or with being able to slice/dice/query/do smth with the shared data? I'm sure there are a bunch of people around here

The snippet you posted will compute an aggregation based on a fixed time interval. I.e. it will put every row into a "bucket" of per-minute granularity and then compute an aggregate function for each of those buckets bucket, takin

It is not statically linked but loaded dynamically at runtime (see my comment above). And I think the .so is not bundled by UPX/shipped with the binary either. I believe this usecase is explicitly allowed by the GPL, but IANAL, so happ

I don't get all the negativity RE: kerf not being open source in this thread. It's obvious the implementation is not free software (check the README in the actual submission) because the author wants to sell commercial licenses. N

Awesome stuff, I am actually hacking on something similar, so I would love to hear your thoughts RE: supporting "windowed" aggregations. (E.g. a moving average over a timeseries). Are you planning on adding that and which syntax a

by paulasmuth 11y ago
Ah turns out this binary actually isn't statically linked at all. It's just the UPX packer that you mentioned that adds a trampoline/stub (the decompression routine I suppose) around the actual binary [and that trampoline cod

Off topic; It looks like you linked the linux binary completely statically. I am curious why you decided to do this and how you achieved it. Did you use something other than glibc to compile these binaries? Also did you roll the SQL engine

I don't seem to get it. How is this different from just using a non-routed IP per container?
