Robert on anything: July 2008

Monday, 7 July 2008. Gogol på Roma Teatern. Igår var vi på Roma Teatern på Gotland och såg på Revisorn av Gogol. Det var en riktigt bra uppsättning och väl värt att se. Jag kan rekomendera att ni går och ser den om ni är på Gotland under sommaren. Det enda tråkiga var att få reda på hur lite bidrag Roma teatern får jämfört med t.ex. riktsteatrar och olika "fria" teatergrupper. Tydligen att göra bra uppsättningar år efter år som folk uppskattar är inte något som prioriteras av stat och kommun.

Sunday, 30 September 2007. Att installera Windows XP på en Dell XPS M1330. I veckan fick jag en ny dator. Det är en Dell XPS M1330, en trevlig liten dator med god prestanda och ett bra grafikkort för att vara så liten. Enda verkliga nackdelen med den är att den endast leveras med Windows Vista. Av någon mystiskt anledning leveras den bara med Vista eftersom Dell anser att det är en dator för privatpersoner och dessa skall. Http:/ www.dellcommunity.com/supportforums/board/message? På det hela gick det myc...

Wednesday, 18 March 2009. Backtracking in Erlang, part 1 - control. Sometimes you need to be able to do search algorithms which can step back and try other alternate ways of finding a solution, "backtracking". Generally this is difficult to do in functional languages like Erlang (most other languages too for that matter). A classic example of this type of problem is parsing ambiguous grammars. Case get a value() of. Choice1 - . ;. Choice2 - . ;. Another problem is that if we have:. And once we have compl...

Sunday, 16 March 2014. After the keynote by José Valim and Dave Thomas at the Erlang Factory in San Francisco. There were of course many discussions on the IRC Elixir channel. Some were advocating a split in the community into two separate communities. I personally think this would be a bad thing for a number of reasons:. Fortunately, from my point of view, there were others who disagreed with this and would prefer to keep it as one community. Labels: Programming and Erlang. Subscribe to: Posts (Atom).

Robert on anything: October 2009

Saturday, 24 October 2009. There has always been much confusion about what a BIF really is, how they relate to the Erlang language. An example of this was a discussion earlier this year when someone wanted to have some more functions in lists coded in C and so become part of Erlang. Saying that they are functions coded in C just tell us how they are implemented not what they *are*. And receive even though they use normal function syntax and semantics. We also decided that it was irrelevant in what la...

Thursday, 9 April 2009. Backtracking in Erlang, part 2 - passing data. In the first part I showed how we could program backtracking in a generic way in Erlang. While Erlang does not directly support it, it is relatively easy to do. In this part we will look at some ways of handling data within this context. The basic problem is how to get data out of a function as in this context functions never return. Fubar(X, Y) :- foo(X, M, N), bar(M, O), baz(N, O, Y). I will show one way how this can done. We wi...

Monday, 20 January 2014. Erlang syntax again . and again . and again . Every once in a while there is a blogg complaining about Erlang and its syntax. To save you the trouble here are the main syntax complaints:. The use of ';' (and ',' and '.') is strange, different and very confusing. I.e. it's not like Java. If' is very strange. I.e. it is not like Java. Variables must start with an uppercase letter. I.e. it is not like Java. The record syntax is very strange. Actually only the record syntax is. A mor...

Wednesday, 19 March 2008. Jag har en Sony Ericsson K610i som för det mesta tycks fungera bra (fast ibland tror jag att den stänger av sig själv). Det som förundrar mig är att när man laddar den så säger den "Optimerad laddning". Då undrar jag förstås om den även klarar av "Ooptimerad laddning" och vad i så fall är skillnaden. Eller är det bara någon marketroid som har en tänkt lite mer än vad han/hon borde? Subscribe to: Posts (Atom). View my complete profile.
