There are a lot of cases when we want to track time when an entity was created or updated. Here is a simple recipe to make some or all of your SQLAlchemy entities auto-timestamping. To achieve this, we will provide a mixin class. from datetime import datetime from sqlalchemy import Column, DateTime, event class TimeStampMixin(object): """ Timestamping mixin """ created_at = Column(DateTime, default=datetime.utcnow) created_at._creation_orde..

There’s nothing that beats the feeling of being part of an exceptional team and yet it is strangely difficult to define exactly what makes one team great and another team not-so-great. Google recently set out to learn how to build the perfect team and came up with some interesting, albeit previously discovered, answers. To summarize their findings, Google’s Project Aristotle concluded that on good teams: All team members spoke roughly..

An analyst writing a DevOps article. Not what you expected? That is exactly the issue I want to tackle here. We have all heard the stories of QAs who ring bells when they find defects, and we are not surprised when developers on those teams are scared of (or annoyed by) interacting with them. In contrast, teams that truly believe everyone brings unique skills to the table and are working together towards the same goal are far more effective..

Every six months or so, we publish our Technology Radar. The radar sets out the changes that we think are currently interesting in software development, the things in motion that we think you should pay attention to and consider using in your projects. It reflects the opinion of our Technology Advisory Board, and is based on our day-to-day work and experiences.

Angular is one of the most popular front-end frameworks. Angular 2 promises to be even more interesting and useful — but it’s also going to be very different from Angular 1. Now that Angular 2 is in beta, what does it look like? Developers are being encouraged to use TypeScript when developing in Angular 2; … Continue reading [Video 458] Kara Erickson and Victor Savkin: Angular 2 updates → The post [Video 458] Kara Erickson and ..

PowerShell is essentially a scripting language and shell (command prompt) that you can use on Windows systems. It’s basically Microsoft’s way of getting a powerful UNIX/Linux/Mac-like shell on the Windows platform (long overdue!). The first versions of PowerShell were pretty horrific, but it’s come a long way since then. PowerShell v4 and later is pretty decent (Win10 comes with PowerShell v5). Luckily, PowerShell v4 comes with Windows ..

Starting with the next update of Codename One (later this week) we will switch Toolbar on as the default for all newly created projects. This doesn’t mean much for most of us as existing projects won’t be affected, however if you are creating a new project this means you won’t need to create a Toolbar for every Form and that we won’t have to deal with as many issues related to the native Android title.

Most people are probably already aware of this fact, but you can test your Ansible-roles on multiple Ansible versions (e.g. 1.9 and 2.0) with the help of Travis . This is done using environment variables . When multiple environment variables are specified, a build will be run for every variable! You can take advantage of this if you specify each version of Ansible you want to test as a variable: env: - ANSIBLE_VERSION=latest - ANS..

This site has been generated using Pelican 3.3 for over two years - and I finally found some time to upgrade to the current version of Pelican, 3.6.3. This is how I did the upgrade. I decided to be lazy and do the upgrade in-place, instead of creating a new virtualenv and copying the content & settings over. Luckily, this worked out OK , after a bit of fiddling around. I also decided, rather cavalierly, to upgrade all the packages in....

Functional programming is well known for, among other things, treating functions as data, allowing us to store, create, pass, and return them within a program. This has led to all sorts of interesting techniques, most having to do with holding onto functions until we need to use them. Object-oriented programming languages offer us a similar … Continue reading [Video 457] Reginald Braithwaite: First-Class Commands — An unexpectedly fertile..

I was working on documenting the SQLite support in Codename One, you can see some of that work both in the db package and in the developer guide . As a demo for SQL I decided to just create a tool that allows you to type arbitrary SQL to execute it on the device and see the results in a Table… Beside being a cool example this can be a hugely powerful debugging tool to one of the more painful API’s to debug on the device.

Senior executives at two of the world’s largest asset management firms recently told us that the industry is filled with bloated enterprises...companies that are designed to move slowly, where good ideas die at the hands of local fiefdoms and bureaucratic decision-making. Their chief complaint? Slow and insufficient response to market changes. Read part one in our four-part series exploring the future of financial services.
