Program Philips Hue

21/07/2019 Ola Løvholm Comments 0 Comment

Phillips’ smart light system Hue has for long been synonymous with smart IoT light bulbs, and although they recently have received competition from IKEA Trådfri and Osram Lightify (and many more), it’s still the dominant platform for smart lighting. Basically Phillips Hue consists of the light bulbs, lamps or light strips which can be either white, white ambience or full colour, as well as the Hue Hub. In addition Phillips also sells buttons and sensors that can be used with…

Into the exclusion zone

25/09/2018 Ola Løvholm Comments 0 Comment

I was born in 1986, and one of the names always being associated with this year is Chernobyl. Yesterday I had the ambivalent “pleasure” to visit parts of exclusion zone: the buffer zone, the Pripyat zone and the 10K zone in which the reactor is located. Towards the end of 2017 a new shelter, or sarcophagus, was put in place over the reactor. This, together with the old shelter and the work of 500.000 liquidators after the catastrophy, makes the…

Push your code onto your EC2 instance with Git

26/06/2013 Ola Løvholm Comments 6 comments

Here is a little thing that has saved me a lot of work, and which I find quite neat. I use the EC2 as my cloud computer. This page (lovholm.net) is hosted on a shared host, but sometimes it’s nice to have the flexibility to run things that are not supported by shared hosts, such as custom software and all that jazz. When I try out different web-things that are not only front-end or PHP I usually create a subdomain…

Facebooksider som RSS

30/01/2013 Ola Løvholm Comments 0 Comment

RSS er super-praktiskt. Enten om du bruker laptop, tablet eller mobil så er aggregerte kilder gull verdt. Hvor digg er det ikke å kunne samle alt du ønsker å lese i en leser (f.eks Google Reader) eller til og med automatisk oppdatere nettbrettet ditt med de nyeste sakene fra dine favorittkilder? Her er en liten oppskrift på hvordan du kan gjøre dette på facebook sider du følger. Det er ikke alltid at social feed plukker opp disse, og dessuten er…

The Gathering 2012

07/04/2012 Ola Løvholm Comments 2 comments

Godt plantet i en stol på Universitetet i Oslos stand på The Gathering i Hamar har jeg god utsikt utover et lyshav a LCD-skjermer og strålende datamaskiner. I en rus av energidrikk, manglende søvn, pulserende musikk og varm frossen-pizza har 5500 personer boltret seg fast i Vikingskipet på Hamar. Etter et par runder rundt i lokalet har jeg observert at spill er den mest populære aktiviteten og på en skjerm i ene enden av lokalet vises spillturneringer på storskjerm. UiO…

Mining the Social Web

22/02/2012 Ola Løvholm Comments 1 comment

Social network sites and interpersonal web communication is big business and plays an ever increasing part of peoples lives. From being mainly a tools for communication has now other life-world domains been conquered by the digital forum for exchange of virtual and real-life information. Both the explicit, and more recently, implicit data footprint produced by acts in the virtual and real world is aggregated, analysed and shared. A member of Facebook sending a wall-post to a friend, a Twitter user retweeting a…

Graduation

07/12/2011 Ola Løvholm Comments 2 comments

The 23rd of November mom, Jules and I went to Scotland to attend my graduation at the University of Edinburgh. In McEwan Hall I meet with most of my old study colleagues and we were in turn hit by the hat which graduates us and bestow our academic titles upon us. This could have been a nice introduction to John Searle and his speech acts, but I will save that for later. Anyhow, this marks the end of my second…

Visuell programmering i Processing

07/11/2011 Ola Løvholm Comments 1 comment

I dag holdt jeg en liten innledning og workshop om visuell programmering hos Norsk Telemuseum på Kjelsås. Jeg ønsket å vise fram programmeringsmiljøet rundt Processing og var også innom forskjellige emner jeg mener er viktig i dagens IT-landskap. I hovedsak orienterte dette seg om data og interfaces, eller data og dingser som jeg kalte det. En artikkel på det kontekstuelle kommer snart, men inntil videre kan du forsøke deg på oppgavesettet jeg lagde til den praktiske gjennomføringen av kurset. Jeg tror…

Start with Ruby on Rails

24/10/2011 Ola Løvholm Comments 1 comment

Over the last two months I have been looking into a new way of doing web-development, and found an ingenious timesaver in the relatively new and popular framework Ruby on Rails. It all started as I wanted to add some back-end functionality to some of the technologies I have experimented with on lovholm.net/projects. Front-end development is exiting with new super-fast Javascript engines, expanded possibilities with the new CSS3 implementation, and easy-to-use frameworks such as Processing.js and jQuery. It is fun…
