[Links of the Day] 29/06/2017 : BeeGFS distributed FS, Virtual memory in Big memory systems, PdfX

  • An Introduction to BeeGFS : Fraunhofer distributed parallel file system for HPC system. Mainly a concurrent of Lustre I would say. This had potential and they are making a foray into the business side of storage. Let's see how well they fare. [website]
  • Preserving the Virtual Memory Abstraction : the author work aims at maintaining the virtual memory abstraction throughout a set of various hardware implementation. [thesis]
  • PDFx : really cool tool that allows you to extract all the reference and metadata and download them!!

[Links of the Day] 27/06/2017 : Blockchain trust & authentication for IoT, K8s patterns, Ripple cryptocurrency Network analysis

  • Kubernetes Production Patterns and anti-patterns :  a lot of common sense, actually a lot of the patterns and anti-patterns can be applied to the other environments. But still a good refresher. 
  • Blockchain based trust & authentication for decentralized sensor networks : using blockchain to solve the trust issue in a swarm of IoT on a network. The critical bit missing is the power requirement for running all the crypto operations.
  • Large-Scale Analysis of the Ripple Cryptocurrency Network : an overview of the paper analysing the Ripple p2p blockchain based money transaction network. Turns out it suffer the same issue that "old school" p2p network. Take out the highly connected nodes and you can bring down / split the network. Nothing new, but still a good read and reminder that small network tends to be resilient to attack. But, if their resiliency diminishes with the increased reliance on a small number of highly connected nodes.

[Links of the Day] 22/06/2017 : Modern Web Dev spell-book, .Net microservices framework, Optimizing Rust

  • Spellbook of Modern Web Dev : like an awesome list for javascript development but with more thought and structure. Must read for front end javascript devs.
  • Microdot : not a .net guy but here is a framework for easily creating .NET Microservices with Orleans
  • Rust Optimization : a lot of stuff can be applied to any language. But, there is some nugget of information for Rust language in this document.

[Links of the Day] 20/07/2017 : Statistics lectures notes, HA transactions, Capability Models for Manycore Memory Systems


  • Lectures on Statistics : 2003 lecture note on statistics, pretty much cover all the basics of what you need to know about stats.
  • Highly Available Transactions : the authors looks at the state of the database transactions system and well like any good scientist their conclusion is that there is more research to be done. But more seriously, highly available transactions and system need to be perfected and new semantics with hybrid systems are required to be developed in order to ensure the availability of transactions. 
  • Capability Models for Manycore Memory Systems : Programming for manycores system is hard, optimising them is even harder. In this paper, the authors try to design models that help programmers to deliver efficient software for these type of hardware architecture. [slides]

Maxims of Maximally Effective Startup Developer


  1. Test, then Deploy
  2. A coding Developer outranks an Architect who doesn't know what's going on
  3. If the food is good enough, the devs will stop complaining about the incoming workload
  4. Only you can prevent prod failure. 
  5. If testing wasn’t your last resort, you failed to resort to enough of it.
  6. The longer everything goes according to sprint planning, the bigger the impending disaster. 
  7. The world is richer when you turn competitors into partners, but that's not the same as you being richer.
  8. Give a developer a task, he will code for a day. Take his software away and tell him he's lucky just to be paid, and he'll figure out how to code another one for you to take tomorrow. 
  9. "Deploy and Forget" is fine, provided you never actually forget.
  10. Don't be afraid to be the first to resort to rollback.
  11. The competitor of my competitor is my competitor's competitor. No more. No less.
  12. There is no over testing.' There is only 'Continuous Integration' and 'I need to spawn more Jenkins slave'
  13. Just because a feature is easy for you, it can still be hard to your clients.
  14. There is a difference between a spare feature and extra [feature].
  15. Not all good news is competitor action. 
  16. “Do you have a backup?” means “I can’t fix this.” 
  17. The size of a developer startup stock options is inversely proportional to the likelihood of the startup surviving to collect it
  18. Don’t try to save money by conserving lines of code.
  19. Don't expect the competition to cooperate in the creation of your dream startup
  20. If it ain't broke, it hasn't been deployed to prod yet.
  21. The dev team you've got is never the dev team you want.
  22. The product management guideline you've got is never the guideline you want
  23. The best way to win a one-on-one architecture design is to be the third to arrive.
  24. It's only too many features if only the devs use them
  25. Don't bring big VMs into small servers
  26. Management knows how to do it by knowing who can code it 
  27. Failure is not an option - it is mandatory. The option is whether or not to let failure be the last thing you test.

[Links of the Day] 15/06/2017 : Corporate Wargaming, ScatterText , Forecasting and BigData

  • Scattertext : Nice and easy to use tool allowing to find independent terms in corpora and present them in an attractive way via interactive scatter plot.
  • Forecasting in the light of Big Data : the authors look at how forecasting is changing in the light of new tool and data collection capability emerge. And as often the authors suggest that the best approach would be to combine model and quantitative analysis in order to obtain the best forecasting strategy. However, I am afraid that this would require a new framework and also training data scientist to leverage this two opposite methodology correctly. 
  • Competitive Wargaming and Simulations for Business Forecasting & Analytics : slide deck providing a good insight on how wargaming can help shape the decision process and strategy of a company. However, like any tool, it's about as much about the preparation and how to leverage the outcome of the game itself.

[Links of the Day] 14/06/2017 : Formally proven HTTPS replacement, Kisrhombille geometry public key cryptosystem using Mersenne Numbers

Everest: Towards a Verified, Drop-in Replacement of HTTPS. The authors ( team of Microsoft, MIT, INRIA) propose a complete, verified replacement of  TLS and other components of HTTPS. Entirely written in F* for provability, Everest is then compiled into a low-level language. This is a highly praiseworthy solution. However, there is still a great portion of the dev world that do not completely embrace or understand formal verification. And until the big corporation ( Google, Microsoft, AWS, etc.. ) start pushing such library the adoption will remain marginal.
Public-Key Cryptosystem via Mersenne Numbers : an interesting new approach to delivering new Public key cryptosystem, for crypto buff only.
Kisrhombille geometry : tessellation of plane using rhombic faces divided in a centre point into four triangles. While Voronoi tesselation tend to still have my preference this type of tessellation has a high potential and like all of them, they are really pretty :)
