ah-··on Hashicorp Vault v1.0
What was your motivation to go with Enterprise?

It seems like most features are OSS now.

ah-··on Looking Glass: an extremely low latency KVM FrameRelay implementation
From what I've seen so far it copies every frame via the CPU and that gets quite slow if you want to do it 60 times a second at high resolution.

Optimus etc. use DMA, so you can copy directly between the two devices.

Hopefully looking glass will support that as well in the future. Last time I looked at least nvidias DMA support was officially restricted to quadro only, so not sure it'll actually happen.

ah-··on Looking Glass: an extremely low latency KVM FrameRelay implementation
If you have two graphics cards and a modern processor you can pass one of them through to a VM that can directly use it with native drivers, so you get native GPU performance in that VM. However that means the picture only goes to the physical outputs of that second GPU.

What Looking Glass does is take the output picture of that GPU and copy it into a window on your host machine.

ah-··on 3factor apps: a pattern for fast iteration, resilience and high scalability
What would you use nowadays to actually implement the real time GraphQL subscriptions and event system in practice?
ah-··on Rapids – Open GPU Data Science
I often run into situations where I hope pandas were 50-100x faster.

Dask can help, but introduces quite a bit of additional complexity.

I'm also looking forward to stricter data models than what pandas currently uses, in particular proper null support for all dtypes and less random type conversion.

ah-··on Nvidia Unveils Quadro RTX, a Raytracing GPU
Their denoising looks interesting: https://www.youtube.com/watch?v=9yy18s-FHWw
ah-··on Important database news from the last few months
kdbs q-sql does improve a lot on that. Especially expressiveness.

ah-··on Ask HN: Are you working on interesting technical problems?
Have you seen https://github.com/pangeo-data/pangeo? It's pretty amazing.

There's still a lot left to figure out, even storage formats aren't fully solved.

ah-··on Ask HN: What SaaS or apps are you paying for?
runbox.com
ah-··on Foundations of Data Science [pdf]
https://mitpress.mit.edu/books/machine-learning-1 is great as well.
ah-··on Commanding infinite streaming storage with Apache Kafka and Pyrostore
I wonder if this would ever be integrated into Kafka proper. Shipping out historical chunks onto infinite storage seems like a generally sensible thing.

This would be even better if it didn't need a modified client.

ah-··on Ask HN: Anyone making money through algorithmic trading?

Worth a read.

ah-··on Apple open-sources FoundationDB
This is amazing! Is there a roadmap of what is being worked on or is this mainly a dump of their existing codebase?

From looking at the commit history it seems like this is pretty actively developed.

ah-··on Ask HN: How do you keep track of your notes at work?
I do the same. A simple text file that's not in git, structured a bit like markdown. I keep it open in vim, so it's always there when I need it.

I've tried using more complex tools like vim outliner and evernote, but simple text files work better for me.

ah-··on CometML wants to do for machine learning what GitHub did for code
Are you planning to open source it?

A lot of your competitors have, like http://pipeline.ai/, https://github.com/pachyderm/pachyderm and recently https://github.com/polyaxon/polyaxon.

ah-··on AWS Public Datasets
Seems to be down. What do they have?
ah-··on Secure Access to 100 AWS Accounts
How are you dealing with software that expect to get aws tokens? Especially with sts AssumeRoles only lasting up to one hour?

For example, if you want to run the Athena JDBC driver locally or read something from S3 in a longish (>1h) running Python script.

ah-··on Google Skaffold – Easy and Repeatable Kubernetes Development
I've switched to https://github.com/boz/kail now, as stern seems to somehow miss pods coming up.
ah-··on Opening the code of our X-Pack features
FWIW, I've done the same recently (deploy ES + Kibana on K8s) and it pretty much just worked. Statefulset, EBS volume claims, official Docker images.

Didn't use XPack or anything fancy though, haven't updated it and the only addon I'm running is https://github.com/lmenezes/cerebro

ah-··on Ask HN: Where do you deploy to in 2018 and how?
Kubernetes, both in-house and on AWS. I couldn't live without it anymore, it's just so nice to use and easy once you've gotten over the initial learning curve.

kubectl apply -f for simple deployments, Helm for more complex ones.

ah-··on Secure APIs Deployed to Kubernetes with OAuth2 Using JWT Tokens Leased by Vault
Vault does the expiration/cleaning up for you.
ah-··on Rainbow Deployments with Kubernetes
Or just a generic reconnect in case the websocket connection breaks for any reason really.
ah-··on ESP8266 ePaper WiFi Display Kit Runs for Months on a Charge
You could hunt for an older ebook reader on eBay with similar hardware if you're willing to spend some time getting it to do what you want. The older Kobos were pretty simple to modify for example.
ah-··on Kdb+ and Python: EmbedPy and PyQ
All this needs now is a free (at least commercial use allowed 64bit version, ideally OSS) kdb+.

I'd love to use this, many things are so much more straight forward in q than they are in pandas. But if it means noone can run my software unless they pay for kdb+ it's a non-starter.

I wonder if this would work with Kona.

ah-··on Kdb+ and Python: EmbedPy and PyQ
I'd start with https://code.kx.com/q4m3/
ah-··on SQL Operations Studio
I think there's a VS Code plugin for CosmosDB.
ah-··on Redis Streams and the Unified Log
That sounds great, I'd definitely come to the meetup!
ah-··on DeepLearning11: 10x Nvidia GTX 1080 Ti Single Root Deep Learning Server
Has there been much progress towards making AMD cards work with popular deep learning libraries?

There's https://rocm.github.io/index.html but it's not quite clear to me how far they got and how usable it is today.

ah-··on Hadoop on IPFS [pdf]
https://www.pachyderm.io/open_source.html does something really similar.
