Fordrevet på ubestemt tid

Situationen omkring atomkraftværket Fukushima 1 er stadig meget kritisk, og den øgede stråling har betydet, at mange indbyggere i området er blevet evakueret.

Minderne fra Tjernobyl trænger sig på, for der er endnu ingen, der ved, hvornår området igen er sikkert at bo i.

Klik på evakueringszonerne for at læse nærmere om, hvad det betyder at bo inden for henholdvis 20 og 30 km fra atomkraftværket.

78.000 uden hjem og tidshorisont

Omkring 78.000 japanere, som boede inden for 20 km af Fukushima 1-værket, er blevet evakueret.

Det er endnu uvist, hvornår de igen kan komme tilbage til deres hjem, men de bliver ikke i løbet af de første dage eller uger, forklarer de japanske myndigheder.

62.000 påvirket

Der bor 62.000 japanere mellem 20 og 30 km fra atomkraftværket. De er blevet opfordret til at forlade området af de japanske myndigheder. Forlader de ikke området, bør de holde sig indendøre.

Evakueringszonen omkring Tjernobylværket var også 30 km. Inden for den grænse er der – 25 år efter – stadig næsten mennesketomt.

Using circles and events in Google Maps – the nerdy part

Here’s a little something I did after reading about the contaminated areas around the Fukushima Dai-ichi Power Plant. The danish newspaper Information has a piece here, CNN got a piece here.

This small tool aids you in getting the coordinates for your polyline or polygon.

By: Martin Ove

Hi all.

I made a little tool, which can make the process of finding coordinates for polygons and polylines in Google Maps a lot easier and intuitive.

It lets you draw a line with multiple points by just clicking on the map. When you’re done, you just copy-paste the coordinates for further use.

If you’re reading this, you probably use a client for Twitter like Seesmic or Tweetdeck on your desktop or some other client on your smartphone. In that case, you probably never overlook a mention on Twitter.

If an object is too small, the cellphone camera won’t focus on it. If you try to get any closer, you’ll be too close for the camera to focus. Thus you get a picture of the background.(Photo: Martin Ove Christensen) Continue reading »

(Click to enlarge) Live Chart Playground helps you build your url. A great feature is the parameter autocomplete function. You don't have to remember that the parameter for axis range is "chxr", you can just begin to type "range". Below the building box is the site with all the documentation you need.

By: Martin Ove

If you want to make a quick chart using Google Charts, you definitely want to know about these sites from Google.

These are both official sites build to help you get started on the API.

First off is the “Live Chart Playground” located here: http://code.google.com/intl/da/apis/chart/docs/chart_playground.html

This is where you want to go, if you want to create static charts, which are data represented as an image. Continue reading »

From CSV to javascript – How to make data fit

Don’t let codes like this be an obstacle when you’ve got a lot of data. There are ways to make them all fit in with a few clicks.

By Martin Ove

Here’s a tip, I found out about while doing a project.

Sometimes you have a lot of data, that you want to fit into a certain format. This happened to me while trying to get Google Charts to work with my dataset, which was stored in pure .csv.

The javascript wanted it to look like this: data.addRow(["Name", Data1, Data2, Data3]);

All I got was this, separated by tabulator: Name     Data1     Data2     Data3

I used Google Spreadsheets to automate the process of putting quotation marks, commas, and space in between the data, check out how below.

The process is extremely universal and might come in handy, if you don’t know it already. Continue reading »
