In recent years, a growing number of coding boot camps have helped address the large gap between available software engineering positions and qualified candidates to fill them. Coding bootcamps have been so successful that observers have wondered whether these programs are beginning to replace traditional college computer science degrees. For example, Aaron Skonnard, the CEO of Pluralsight, argues in Edtech’s Next Big Disruption Is The College Degree that college degrees will be replaced by “a new array of modern credentials that are currently gaining mainstream traction as viable measures of learning, ability and accomplishment.”
Bezier Curve In Games
Bezier curves are the most fundamental curves, used generally in computer graphics and image processing. Bezier curves can be used for creating smooth curved roads, curved paths just like zuma game, curved shaped rivers, etc. in your game.
LibreOffice Online is here!
This week Collabora has shown an early testing version of the cloud version of LibreOffice integrated with an Owncloud instance. To me and others, this marks a significant milestone in the story of LibreOffice and the Document Foundation. I’m aware that the code is not stabilized and there’s much work left to do, but by and large, LibreOffice now has its own cloud version. The repercussions of this won’t be immediately clear, in that they will likely really start when the first stable version is released along with a proper documentation so that anyone who has to administer 15 desktops can easily install and run it.
A Beginner’s Guide to Caching Data in Drupal 7
Building complicated, dynamic content in Drupal is easy, but it can come at a price. A lot of the stuff that makes a site engaging can spell ‘performance nightmare’ under heavy load, thrashing the database to perform complex queries and expensive calculations every time a user looks at a node or loads a particular page.
One solution is to turn on page caching on Drupal’s performance options administration page. That speeds things up for anonymous users by caching the output of each page, greatly reducing the number of DB queries needed when they hit the site. That doesn’t help with logged in users, however: because page level caching is an all-or-nothing affair, it only works for the standardized, always-the-same view that anonymous users see when they arrive.
Eventually there comes a time when you have to dig in to your code, identify the database access hot spots, and add caching yourself. Fortunately, Drupal’s built-in caching APIs and some simple guidelines can make that task easy.
Make a Weather Station With a Raspberry Pi 2
A core part of the “Internet of Things” movement is the idea of devices that gather data and send it to the Internet. That data is then acted on or observed for later. It’s a simple concept and has been going on for a while but lately it’s been getting cheaper and easier to do. This project is a great example of that.
While this seems like a long tutorial, it only takes about 30 minutes to complete. Let’s get started.
Once you complete this project, your Raspberry Pi will measure:
- Temperature
- Humidity
- Atmospheric Pressure
- Lux

Do We Still Need Computer Science Teachers?
These days it seems like “how to learn coding yourself” opportunities are everywhere. There are MOOCs from major universities, code.org (http://code.org) has great online tutorials, Facebook just opened a web site called TechPrep (https://techprep.fb.com/) to help parents and students alike find resources and tools, and there seems to be a new edtech company starting up every week with online CS resources. The question for many becomes “do we still need computer science teachers?” Συνεχίστε την ανάγνωση του “Do We Still Need Computer Science Teachers?”
5 Ways to Use Google Sheets in the Classroom
Google Sheets has many features that make it ideal for curation and organization of information. Here are some ideas for educators to think about as they begin to use Google Sheets in the classroom.
1. Gradebook
Easily organize and access your grades anywhere with Google Sheets!
- Create graphs for individual students that you can share with students or parents.
- Use functions to figure out your final grades.
- Using conditional formating to visually organize your data.
2. Organize Resources
Since you can easily incorporate hyperlinks into a Google Sheet, you can gather resources for your students and keep it one central location. Using the formatting features and multiple sheets allow you to create a document that’s easy and clear for students to navigate.
3. Create Flashcards
Use Flippity.net to create flashcards or have students create their own to help them review. Take some time to explore Flippty, there are other programs there to try too!
4. Explore and Share Graphs
Students can collect data, determine how it should be organized in their sheet and then use the chart feature to create a graph that best fits their data. The graphs can then be easily shared on a class webpage, wiki or blog, where students can share their findings and conclusions with others.
5. Use Templates
There are a variety of templates already created for teachers to make your life a little easier! You’ll find gradebooks, attendance sheets, schedules and more in the template gallery.
Raspberry pi: Weather station for Schools
The goal is to have the Pi controlling everything, so that we could leverage learning opportunity: helping kids to learn about writing code to interface directly with the sensors, as well as displaying and analysing collected data. For example, look at the following set of sensor measurements for the weather station:
- Rainfall
- Wind speed
- Wind gust speed
- Wind direction
- Ambient temperature
- Soil temperature
- Barometric pressure
- Relative humidity
- Air Quality
- Real Time Clock (for data logging purposes).
