Hello,
Do not assume anything. Never. Ever. Specially with SparkR (Apache Spark 2.1.0).
When using the gapply function, maybe you want to return the key to mark the results in a function as follows:
countRows <- function(key, values) {
df <- data.frame(key=key, nvalues=nrow(values))
return(df)
}
count <- gapplyCollect(data, "keyAttribute", countRows)countRows <- function(key, values) {
df <- data.frame(key=key, nvalues=nrow(values))
return(df)
}
count <- gapplyCollect(data, "keyAttribute", countRows)SURPRISE. You can’t.
You should get this error:
Error in match.names(clabs, names(xi)): names do not match previous names
Well, that’s weird. Why is this happening?
Hey!
Recently I bought a broken 75P just for fun (and well, it was cheap :)). It had a video problem which, after reading a couple of msx.org posts (Hit-bit With Broken Graphics and 75P black screen mainly), I believed it was a problem of VRAM as Grauw pointed.
That was a clever way to debug it. Watching how Basic characters are output, you can see which bit is broken in the ASCII chart. Why can you point to which bank is failing if a bit fails?
You can do as this tutorial says: Headless VNC-Server using xvfb
Very cool application for the phone. You can easily load .cas files on the phone and play them :).
Hello!
Finally some improvements on asMSX. At the start of this project JamQue told me that he had issues using ifs when the “.megarom” clause is active. The issue correction can be seen here in Github.
The problem was that when generating a byte (for example, an LD instruction) it checks if it is able to generate it if the condition established for this level allows it.
Original:
guardar_byte(b)
{
if ((!conditional_level)||(conditional[conditional_level]))
if (type!=MEGAROM)
{
...some code...
}
if (type==MEGAROM)
{
...some code...
}The first if will only affect the if(type!=MEGAROM) as it doesn’t provide brackets to define a block, therefore it will get only the next sentence. Also instead of doing if(type==MEGAROM) I just did an else.
So, once again I tried to discover which genre of the song “Men of war”, which is part of the OST of Breath Of Fire IV (A quite nice PlayStation RPG :)).
I tried from tabla breaks to tabla dnb… couldn’t find it. Until now!
I found this video with a bunch of dnb indian stuff. It misses the tabla but it’s nice!
Hello everynyan,
I’m learning how Bison and Flex work with an O’Reilly book and there can be found an example on how to build a calculator (which has an error on the code, probably there are more in the book, that’s why it has that kind of critics, but it works.).
I ended up making an extension on it just to test my forgotten grammar skills. The code is the following:
