I'm not a Fortran coder but I need to call the sub-routine ADAPT.f from a c code.This subroutine calculates a multiple integral of a given function.My problem is that the c code works with no problem in a 32 bit machine but it does not in a 64 bit machine, and the problem seems to be related to adapt, which calculations gives a NA rather than the result of integration.Since fortran is quite obscure for me, I don't know why is this happening. Maybe I should change some data type (from real to double), but I'm not sure. Does anyone have a clue?
View 3 Replies View RelatedFrom reading around the web, it looks like Firefox's "quick view" of an RSS feed sometimes lets you "Subscribe to this feed using" Thunderbird. For whatever reason, that's not an automatically-added option with my setup (FF 3.5.something + Thunderbird 3.0.something on Linux), so I figured I could just "Choose Application...", point at the Thunderbird binary, and be on my way. Not so -- nothing appears to happen. If I run thunderbird from the command line as
thunderbird "http://path/to/feed" the app launches as normal. If it's already running, absolutely nothing happens. Is this impossible? Is there some mojo I can pass Firefox to tell it that Thunderbird exists? Should I just suck it up and copy/paste the URLs manually?
Is there a way by which I can read RSS feeds from the terminal itself ? Something that would display the titles and a link to follow. Or maybe a software which works from within the terminal.

I can't figure out how to feed only one line of the .info file to the if statement at a time so that it will perceive it as an integer instead of a list.

View 4 Replies View RelatedI have some file tools on a mint machine that I would rather not install on my mac laptop. Mainly because of the vastness of apt-get and the low risk of installation failure. Anyway, every so often I have a file that I want to process in place using some remote tool. Both machines can ssh right in to each other so I was figuring there must be some script or tool out there that would allow me to type out something like remote [file] [tool & args] to send my file to the other machine, get it processed, then get it back.

I want to create my own Atom feed file covering some informational posts on a web page. I will maintain it by hand, so I would prefer it to be as minimalistic a file as possible, yet still a valid Atom file.I found Atom specification documents online, but there was so much information I felt like a rowboat on the Pacific ocean. I did not find a specific section declaring exactly what /had/ to be in a Atom feed file.

I've got the clients working when I drop a torrent into the folder just fine, but FlexGet is giving me some trouble. I'm using feeds from EZTV & EZRSS to get the torrents for a show. I've used the feeds for months for uTorrent in Windows, so I know they're good. Below is my ~/.flexget/config.yml file.
Code:

Error) download download Failed The Daily Show 2011-01-17 [HDTV - FQM] (URL Error) This happens for every torrent in the feed. I think it has something to do with it substituting %28 for [, %29 for ], and so on, but I'm not sure how to fix it (or if it's actually the problem).
I have three different webcams. All Logitech. Two are "cheapo" ones, and one is a more expensive, HD one. I'm running the stock Maverick desktop install, with no specifical extras for the video or the like. I plug in the webcam (doesn't matter which one I use) and it is picked up and can be used. Not a problem, but when I view the feed, the its laggy and choppy. If I plug in the cam onto my Windows XP or Window 7 installs (on the same laptop), the feed is smooth and has no issues. So I figure it has to be something to do with my settings or configurations. Problem is, I can't seem to find out what I need to tweak to smoothen or improve the feed. I've tried reducing the resolution of the feed to the minimum, but that hasn't helped.
Just to give you an idea of what I'm talking about. If I film myself typing at my laptop keyboard, I can see my hands move around the keyboard when I view the footage in Windows, but when I film it in Ubuntu, it's very jumpy, and my hands seem to jump about all over the keyboard -- almost as if something can't keep up.

Trying to stream a live video feed from Rock am Ring which is available via the German SWR3 TV website. Trouble is, I am in the UK and it seems to only be avaialable to German IP addresses.

Getting the error from the server, Server Error The connection to the streaming server has been disconnected. Any networking gurus out there who may know a way around this.
