> If a beginner wanted to do anything "cool-looking" today, this same beginner programmer would need to set up render to texture on an OpenGL surface. Yuck! And so they lose interest, believing programming is the mysterious and complex domain of gods.

Or just use the web platform: JavaScript, HTML5 Canvas API, WebGL, all of that. I think it's pretty close in terms of getting a pretty (motivating) result quickly without much prior experience.

(Unrelated, but I can also remember writing the first lines of code of my life in qbasic on a dos machine in ~1998; the blue screen definitely invokes childhood memories!)

>> Well, yeah. That's 28,108.80 a month

If you can't (or don't want to!) afford that kind of money for data analytics, please consider giving the FOSS alternative EventQL [0] a try some time.

It's super simple to set up and tries to be efficient on commodity hardware, so you can run large clusters (>100TB scale) for a couple hundred dollars a month.

>> For example in germany FF is still the widest used desktop browser.

Do you have any references to back that up? I'm asking because I suspect your assumption is completely wrong.

(Based on a bunch of analytics data that I have access to, which might not be representative but still contains some very large german web properties, chrome has more than twice the market share compared to FF in germany).

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 soundcloud [1] if you don't want to review the code. It's open source after all, which can't be said for most demos...

BTW I do actually enjoy the linked music (allthough I have to admit I'm listening on soundcloud)!

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). Had an absolute blast and didn't feel like I was missing a thing.

>> So it's a completely different class of application than splunk or elasticsearch

Sure it takes a somewhat different approach (i.e. it requires an explicit schema), but for the use case discussed in this thread it _is_ completely relevant and a comparable open-source/on-premise alternative which parent was asking about.

>> one that you have a commercial interest in

Yes, I'm involved in the EventQL project but I thought that it was obvious from the way I phrased my posting. Usually I always include a disclaimer to prevent misunderstandings but I didn't consider it necessary in this case.

>> Please don't spam HN.

I don't think pitching a (relevant) startup is against the rules or the spirit of a startup forum (https://news.ycombinator.com/newsguidelines.html)

> I'm still surprised that there's no startups offering comparable (particularly on-prem) products

Please consider giving EventQL [0] a try some time! It's completely open-source and self-hostable. Still a new project though, just released this summer and still in beta.

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 sources. All other worakrounds are vendor-specific and not part of the standard.

[Of course even objects containing only C symbols are not portable across platforms either, but at least the C ABI/calling convention is more or less strictly defined for any given target platform. Assuming no other platform-specific stuff like glibc is used]

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 working on a system that is somewhat similar to CitusDB (eventql.io) and am always really interested in these numbers]

EDIT: I can't reply to your other comment for some reason but many thanks for digging that up, it's very interesting info to me!

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?).

paulasmuth — Fri, 09 Sep 2016 12:24:08 +0000

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. same version of the compiler/same compiler source code) and with the exact same flags. I'm sure there are some compiler vendors that offer ABI backwards-compatibility but it's not part of the C++ language per-se.

See this article by Herb Sutter on the topic: https://isocpp.org/files/papers/n4028.pdf

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. Allthough your machines seem to be quite a bit beefier (I wonder if all that RAM is actually used?).

> Except for inlineable functions and templates in C++—which become a greater and greater fraction of code the more "modern" your C++ gets.

The C++ ABI is currently not portable anyway. So the concern about templates (or any C++ features) forcing you to put the implementation into the header file would not apply in the scenario dllthomas was referring to:

If you want to distribute your library as a binary object and a separate source-form interface/header today, you'll have to use a (wrapper) C API. Regardless of how "modern" the C++ code is.

Of course, it would be nice to have portable C++ objects some time in the future which would change things... :)
