Publicly funded research should be #OpenSource #OpenData #OpenAccess #OpenScience - free for educational use not enough, widen dissemination

A long-delayed post about importing the standard library in C++ using the latest CMake 3.30 release and a recent Clang 18.1.8 toolchain. It works (mostly) and continues to improve! I linked to a few accompanying commits where you can see the details too https://t.co/hJxx4mlWAM

One year at a startup already! Hard to believe, a quick post reflecting on my journey and what I enjoy about startup life. Really an opportunity to take stock as this was quite a shift in career for me https://t.co/6W3uBIayTK

Summer is upon us!!! ☀️ 🏝️

Despite the cold spell the passion flower has bloomed! Got a hanging basket from our neighbor's farm, it did really well a few years back.

Lena and I started working on this project almost 10 years ago, with @ktspoth and then Yue taking data. Lena passed away before she could finish the paper, even as other groups were finding it very useful. With Yue and friends we finally finished it!*

A few of my thoughts after #GTC24, inspired by a colleagues write up and reflecting on my journey over the years with GPUs

GTC was crazy, great to be back in person, very different to the GTC events of the past

[Josh Patterson @datametrician]

10 years of "it can't be done..." 7 @nvidia GPU architectures... 5 years of @RAPIDSai... 3 years of @VoltronData... finally a petabyte-scale GPU-native engine that DOESN'T require you to change your data pipelines. Same code, same data formats, just modular, interoperable, composable, extensible... and of course ACCELERATED!

Theseus is the Scalable Performant And Compute Efficient engine🔥🔥🔥

Check out our benchmarks and new webpage... and reach out if you're struggling with queries above 30TBs.

[Voltron Data @VoltronData]

Meet Theseus - the petabyte-scale query engine redefining the #DataAnalytics SPACE - scale, performance and cost efficiency. 🚀 Process hundreds of TBs in seconds & unleash GPUs for real-time insights. 👉 Unveiled at #NVIDIAGTC: https://t.co/DHQPU7UROh

[Marcus D. Hanwell @mhanwell]

I will be at GTC next week, can't wait for it!

[Josh Patterson @datametrician]

Next week @VoltronData will be at @NVIDIA #GTC24 along with partners @LambdaAPI & @HPE bringing serious news for our engine, Theseus, directly to you 🔥🔥🔥. I haven’t been this hyped since launching @RAPIDSai. Reach out to meet with me or my team to connect!

[Marcus D. Hanwell @mhanwell]

We are hiring for a Staff Build Engineer role. Do you have experience with C++, CMake, compilers, CI, software development processes, open source and working with dependencies. Do you think this is you, or know someone who might be a good fit? https://t.co/Ks6c1emrH5

[Josh Patterson @datametrician]

That’s it folks 🔥🔥🔥
Why @IbisData is epic!
Plus works with distributed backends like @ApacheSpark @trinodb, GPU backends like @RAPIDSai #cuDF and @VoltronData Theseus, and streaming backend like @ApacheFlink and @RisingWaveLabs!

[Marcus D. Hanwell @mhanwell]

A bit of a tangent on the importance (in my opinion) or toy projects, pointers to past posts on C++, CMake, C++ modules, packaging, C++ with a columnar database and some hints at areas I hope to find time to dig into more in the future plus Lego! https://t.co/hwIHtmMpPC

[Marcus D. Hanwell @mhanwell]

First baby steps looking at using DuckDB in a simple C++ application. It looks cool and I am certain that I am missing the best path. Still I got an in memory database linking to the library and making a few calls, and it looks easy to deploy https://t.co/fl1FhfYpAa

[Marcus D. Hanwell @mhanwell]

A more personal post marking six years since I naturalized as a US citizen and reflecting a little on how much has changed since then https://t.co/HRPrQmCtez

[Marcus D. Hanwell @mhanwell]

New post looking at vcpkg replacing superbuilds in cmake-based C++ projects with some examples using a small project https://t.co/ds0kqfNPKq #cmake #cplusplus

[Marcus D. Hanwell @mhanwell]

Taking a look at C++ module support in CMake and Clang on Arch Linux. Follow along as I make my first module and do the obligatory "ello" world. Also tiniest fragments of CMake to set up a project that creates a module https://t.co/pphiriWk0M

[Marcus D. Hanwell @mhanwell]

Made it to 💯

Clear ice, orange twists, upping my cocktail game

[Marcus D. Hanwell @mhanwell]

@ifndef_define Thanks, definitely hoping to get back into a little of my open source chemistry work but loving it so far. I hope you are well @ifndef_define

[Marcus D. Hanwell @mhanwell]

It has been about a half year already, I just posted about my recent move to Voltron Data, open source and career. Exciting times! https://t.co/V454A9du9h
