RIP WINDOWS 10


This enough...after a year struggling with Windows10 fast boot, secure boot, registered keys, UEFI files and endless updating, I cleaned the whole hard drive. Back to Linux again: installed Mint 17.3. All the data journalism stuff: Excel(office online) or Calc(Open Office, Outwit-Hub or table capture Chrome, Refine, Tabula, Qgis, R and R studio; all working. Just in case: running Win10 in a virtual box.
One small problem: I love Tableau public for viz. Not available for Linux (yet)....starting with plot.ly. Better integration with R.

JUPYTER NOTEBOOK


Making visualizations like maps or charts is the end product for many data journalism research. When you want to explain the structure of the research and the different steps of the data journalism research, problems emerge. Or when you want to make the research more transparent by sharing the outcome of the different steps of the research. For example I am using R for analysis and plotly for visualizations; for showing the different steps I am have a text describing the whole process in markdown. During the lecture or a training you have to switch from one application to another. Jupyter notebooks solves this problem, because by using different kernels in the notebook you can show text in markdown, calculations in R, and visualizations in plotly. You can also share the notebook with the data, so anybody can after downloading follow the research process step by step.

Training Tanzania's next Data Journalism Leaders

TMF and EJC continue to deepen their commitment to data journalism in Tanzania by implementing their first workshop targeting the country's need for data journalism trainers. Kicking off 17 July in Dar es Salaam and led by former Utrecht professor, Peter Verweij, the programme features sessions led by participants themselves and dives deep into the local context of controversial statistics and cybercrime laws recently passed by the government.

During the workshop, the newly published Swahili language version of EJC's Data Journalism Handbook is being released and distributed to journalists across Tanzania and Kenya both digitally and hardcopy.

TELEGRAM AND BOTS


Are you still using Whatsapp? That is old school and there are good reasons to switch to another service. Telegram Messenger for example. After Facebook bought Whatsapp, the chances that your privacy was endangered, were increasing. Of course Facebook created a possibility for users to opt out, that is Facebook had no access to the whatsapp data…. For the moment. The first reason for me to look into Telegram was, that it is completely cloud based. You login to your Telegram account with a mobile phone, a tablet, or your laptop, using an app or just the browser. Secondly Telegram offers more possibilities for including files to your message. Not only pics but audio, video, or text files can be attached. Nice but that was not compelling for me to switch. That was the possibility or using bots and also creating your own bot.

How does it work? Installing the messenger service is a piece of cake. Download the app and subscribe. A pin code is end to your phone to login; done. In your contact you can see who is already using Telegram. Others you can send an invitation.
