Scaphandre v0.1.1 : mesurer la consommation d’énergie (des coulisses) du numérique - Benoit Petit

Scaphandre, un logiciel open-source de mesure de la consommation d’énergie d’un serveur informatique ou ordinateur, mais aussi des services et applications qu’il exécute. Plus précisément, scaphandre est à la fois un outil utilisable en ligne de commande et un démon (service).
Le projet a notamment pour objectif de rendre la mesure de consommation d’énergie suffisamment simple pour que ça devienne “un basique”, au même titre que le nombre de requêtes par seconde ou la latence, le temps CPU consommé ou la RAM, etc…

It always seems impossible until it’s done. — Nelson MandelaIntroductionAny financial application with a minimum of complexity will need some decimal support and multiplications to calculate things like interest. In the case of CementDAO we needed logarithms to implement the transaction fee curve that steers its cryptocurrency basket towards the desired configuration.Solidity supports integers but no decimals, so we coded a fixed point arithmetic contract, made it safe against overflow, and tested it extensively. It underpins the CementDAO deployment in Ropsten.The Fixidity contract is available from the CementDAO github with a MIT license, please feel free to use it and build upon it.ImplementationIn order to code this we went from the simplest to the most complex arithmetic functions, (...)

The future of software development: modular, intelligent, and rickety

The future of software development: freelance, AI-assisted, and ricketyNearly four thousand years elapsed between when Egyptian astronomers invented the concept of zero and a British mathematician tacked together the first computer. But once the thing was made, we were off to the races. It was only 130 more years to electronic computers, 40 to the internet, and only nine to smartphones. Now advances in computer science pop off as if discharged from a ticker tape machine.But not everything that earns press sees success — or has an impact. Most inventions die following their hype cycle, in what research firm Gartner calls the trough of disillusionment.

Semantic Versioning 2.0.0 (semver.org) is a robust and elementary standard that encapsulates a wealth of information about the software you’re publishing or consuming.Open source veterans know and understand the importance of this standard. If you’ve run a project in long-term maintenance mode, you come to realize its power one way or another. Still, enthusiastic, fast-moving dev teams like to find ways around this standard. I’ve seen more than a few engineers decide to invent their own ideas around major, minor, and patch increments. Their rationale is rooted in aesthetics or their own release schedule.A key principleAside from the concise and complete information at semver.org, it is critical to understand:Semantic versioning is for your consumers.

Help Authoring Tools (HATs) are a useful addition to any business — whether you have teams of technical writers, just one, or other employees pitching in, producing documentation remains essential for teams who want to improve their products or comply with regulations.HATs are typically used to help you produce large amounts of documentation that is centrally managed by your technical writing team.Some common Help Authoring Tools are industry standards like Madcap Flare or Adobe RoboHelp, and they enable you to single source (...)

There’s little argument that open source has transformed our world. As a developer, I cannot recall a single day in the last few years where I did not rely on open source software. I’m not the exception. The majority of software engineers today rely on open source daily in their professional lives.For one, open source is dominating developer infrastructure. From operating systems (Linux in the cloud) to databases (MySQL, MongoDB, Redis) to programming languages themselves (JavaScript, Python, Java, C, PHP). It’s not just developers, it’s consumers as well. From what they run on their phones (Android) to how they access the web (Chrome, Firefox).The motivation is clear. Open source is good for humanity. It is making technology more accessible and open — anyone can build anything.Open source (...)

Lumi #blockchain WalletOpen-source is one of the major concepts in the #cryptocurrency space as the whole industry basically grew up on it. Nowadays, building a crypto project without publishing at least a part of your code on #github is considered to be bad manners.Most of the developers involved in open-source projects are driven by the same goal: create a product that they will use themselves. This way, you get deeply involved and know about every single issue at stake. Could you think of better motivation?But there’s a flip side to this. Running a business based on an open-source model can be rather tricky.Firstly, you have to consider that it’s going to, at the very least, double the duration of the whole development process.

Since the last half year, we have seen a downturn of the crypto-markets and the rise of public chains. Almost every week, there are a lot teams announcing their plans of launching public chain. The unprecedented passion for public chain makes an illusion that building a public chain just needs to set up several nodes.However, Rome was not built in a day.The establishment of a public chain is not an easy task. Even the top cryptocurrency exchange, HUOBI has not given a clear declaration of the launch date after investing 30 million HT to develop the public chain(nearly more than 600 million RMB). Actually, the development of public chain requires very large R&D investment, as well as the technical team support and maintenance cost. Also, it is quite costly to organize a large number (...)
