- Aphyr Scala Day 17 : Aphyr breaks database for a living and then talks about it :)
- Sia : a Blockchain-based marketplace for file storage, the really attractive thing is the cost comparison of SIA vs public cloud system. Which is between a tenth to a hundredth time cheaper than S3 or other similar solution. I would be curious to see the performance thought.
- How brains are built: High-level overview of principles of computational neuroscience.

[Links of the Day] 24/04/2017 : Data Center Perf Index, Physical Limits of Computing And DNS as Code
- Data Center Performance Index : Performance index aiming at providing a reliable idea of the performance and efficiency of the datacenter. It primarily focuses on Availability, Efficiency and Environmental impact. This effort is lead by Dean Nelson, Uber Had of computing.
- Physical Limits of Computing : A look at the limitation of compute from a physicist point of view. It seems that some limitations are fundamental and require a new and different approach in order to create compute device that goes around these limitations.
- DnsControl : system built to manage DNS systems. To some extent, it looks like a terraform for DNS where you can plug multiple DNS backend providers. This allows you to deploy and distribute your DNS infra in an agnostic way across multiple cloud provider. [github]

[Links of the Day] 21/04/2017 : HPC 2017 trends, Docker cheat-sheet, Incident response best practice
- Current Trends in High-Performance Computing and Challenges : Jack Dongarra annual HPC review, It's amazing how the chinese progressed. They literally took over the top 500 in less than ten years. And now they dominate using homegrown chips and network fabric. [slides]
- Docker cheatsheet : 'nough said.
- Increment - On-call : New magazine providing article on how to scale companies. Each edition focus on a different topic. For the inaugural issue, they focus on industry best practices around on-call and incident response.

[Links of the Day] 19/04/2017 : AMD ROCm GPU open platform, Weak Memory Models concurrency report, SSH server for distributed infrastruscture
- ROCm : this slide deck give an overview of the AMD ROCm open platform for GPU computing exploration. They are really pushing to become the open source standard for the GPU industry battling against NVIDIA supremacy in the domain. It looks like they are making really good progress and I would be curious to see how this progress when combining with their Ryzen CPU.
- Concurrency with Weak Memory Models : this is a really good report on the state of memory models in hardware and software. It provides a wide spectrum overview of Hardware and Software concurrency model and approaches as well as the future direction in the domain.
- Teleport 2 : a modern SSH server designed for teams managing distributed infrastructure. [github]

[Links of the Day] 17/04/2017 : Pedis Redis Clone, Serverless framework, Deep learning best practices
- Pedis : Redis Compatible NoSQL datastore using the Seastar Framework. It's interesting to see that on the single thread benchmark Redis and Pedis are on par while it Redis gets smoked on 8 thread benchmark. However on a side note, the author should probably have chosen another name for project.
- serverless : Serverless Framework with serverless architectures using AWS Lambda, Azure Functions, Google CloudFunctions [github]
- Best Practices for Applying Deep Learning to Novel Applications : this is pretty much a must read for machine learning expert using deep learning. This report decomposes deep learning project in phases and provides best practice for each phase.

- OpenFabrics Workshop 2017 : Some interesting talk this year at the open fabric conference:
- uRDMA : Userspace RDMA using DPDK. This opens up a certain amount of possibility, especially for object storage solution. [Video , Slides, github]
- Crail : Using urdma above to deliver accelerated storage solution for Apache big data projects [Slides, github]
- Remote Persistent Memory: I think this is the next killer app for RDMA. If Intel doesn't jump onto it and deliver a dpdk like solution. [Video, Slides]
- On Demand paging: slowly the tech is crawling its way up to upstream acceptance. While on-demand paging introduces a certain performance cost. It also allows a greater flexibility in consuming RDMA. One of the interesting aspects that nobody mentioned yet is how this feature could be used with persistent memory. I think that there is some good potential for p2p NVM storage solution.[Video, Slides]
- Containerd : Containerd move to github, the docker "industry standard" container runtime is also reaching its v.0.2.x release. [github]
- Category Theory : If you are into functional programming and Haskell. This is a must read book for you.

[Links of the Day] 12/04/2017: Linux Perf tools, libp2p and Contagion of Information in Social Media
- Perf Tools : miscellaneous collection of in-development and unsupported performance analysis tools for Linux ftrace and perf_events.
- Contagion of Information in Social Media : The authors look at how information spread on social media ( twitter ). The authors model contagion behaviour in the hope to create effective defences against "fake news" and other propaganda. However, to some extend the research can also be used to optimise the spread of such malicious information.
- libp2p : really cool network stack ( used by IPFS) that tackle a lot of the nitty gritty detail of p2p applications. It should allow devs to focus on the actual value of their p2p apps rather than the technical underlying problems of p2p itself. [github]
