Permission denied problem in Freenas + Transmission

- by Torbjörn Karlsson

Running Freenas 0.7.2 (5543) and Transmission 2.11 The problem it that i can not save a torrent where ever i want.. For example... I can save in: /nmt/1-500gb/Tv/dexter but i can not save in /nmt/4-1000gb/tv/Lost When i try to save in the lost folder I get a permission denied error in the Web interface. But when I try to save the same torrent file in the dexter folder everything works fine... This is probably an easy thing to fix, but I'm new to Freenas. The user name for Transmission is TorrentUser if that helps. Now I find out that I can not browse the disk in Quixplorer.. I can browse nmt/4-1000gb/ but not /nmt/1-500gb When I try to browse the nmt/4-1000gb/ I get Unable to read directory $ mount /dev/md0 on / (ufs, local) devfs on /dev (devfs, local) procfs on /proc (procfs, local) /dev/fuse1 on /mnt/5 - 500gb (fusefs, local, synchronous) /dev/fuse2 on /mnt/2 - 1000gb (fusefs, local, synchronous) /dev/fuse3 on /mnt/3 - 1000gb (fusefs, local, synchronous) /dev/fuse4 on /mnt/4 - 1000gb (fusefs, local, synchronous) /dev/fuse5 on /mnt/320GB - USB (fusefs, local, synchronous) /dev/md1 on /var (ufs, local) /dev/da0a on /cf (ufs, local, read-only) /dev/fuse0 on /mnt/1 - 500gb (fusefs, local, synchronous) Dont work : 1 - 500gb 2 - 1000gb 3 - 1000gb Works: 320GB - USB 4 - 1000gb 5 - 500gb And this 3 disk is the same disks that I can save my torrents to. Ps. Every disk works perfect when i use ftp...

JNI: Long-object created with wrong value

- by Torbjörn Eklund

Hi! I am writing a c-jni function in Android, and I am having problems with creating a Long-object. I have succeeded in calling the constructor, but when I read the value of the object with longValue, I get the wrong result. jmethodID longConstructor; jmethodID longGetLongValue; jclass cls; jobject obj; // Create a object of type Long. cls = (*env)->FindClass(env,"java/lang/Long"); longConstructor = (*env)->GetMethodID(env,cls,"<init>","(J)V"); obj = (*env)->NewObject(env, cls, longConstructor, 4242); // Get the value by calling the function longValue. longGetLongValue= (*env)->GetMethodID(env,cls,"longValue","()J"); long return_long_value = (*env)->CallLongMethod(env, obj, longGetLongValue); // Log the result. LOGD("%li", return_long_value); I would expect that the above code would print 4242 in the log, however the value that is printed in the log is 1691768. Does anybody have an idea on why 4242 is not written in the log?

How do you unbind variables in an interactive Erlang session?

- by Torbjørn

In the Erlang interactive shell you can bind variables to values. If I would like to clear everything and start from scratch without exiting the session and starting a new one, how do I do that? And if I just wanted to re-use a single variable, is it possible to re-bind?

Setting WPF image source in code

- by Torbjørn

I'm trying to set a WPF image's source in code. The image is embedded as a resource in the project. By looking at examples I've come up with the below code. For some reason it doesn't work - the image does not show up. By debugging I can see that the stream contains the image data. So what's wrong? Assembly asm = Assembly.GetExecutingAssembly(); Stream iconStream = asm.GetManifestResourceStream("SomeImage.png"); PngBitmapDecoder iconDecoder = new PngBitmapDecoder(iconStream, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default); ImageSource iconSource = iconDecoder.Frames[0]; _icon.Source = iconSource; The icon is defined something like this: <Image x:Name="_icon" Width="16" Height="16" />

Combining multiple rows into one row, Oracle

- by Torbjørn

Hi. I'm working with a database which is created in Oracle and used in a GIS-software through SDE. One of my colleuges is going to make some statistics out of this database and I'm not capable of finding a reasonable SQL-query for getting the data. I have two tables, one with registrations and one with registrationdetails. It's a one to many relationship, so the registration can have one or more details connected to it (no maximum number). table: Registration RegistrationID Date TotLenght 1 01.01.2010 5 2 01.02.2010 15 3 05.02.2009 10 2.table: RegistrationDetail DetailID RegistrationID Owner Type Distance 1 1 TD UB 1,5 2 1 AB US 2 3 1 TD UQ 4 4 2 AB UQ 13 5 2 AB UR 13,1 6 3 TD US 5 I want the resulting selection to be something like this: RegistrationID Date TotLenght DetailID RegistrationID Owner Type Distance DetailID RegistrationID Owner Type Distance DetailID RegistrationID Owner Type Distance 1 01.01.2010 5 1 1 TD UB 1,5 2 1 AB US 2 3 1 TD UQ 4 2 01.02.2010 15 4 2 AB UQ 13 5 2 AB UR 13,1 3 05.02.2009 10 6 3 TD US 5 With a normal join I get one row per each registration and detail. Can anyone help me with this? I don't have administrator-rights for the database, so I can't create any tables or variables. If it's possible, I could copy the tables into Access.

Using Sessions in WCF Services called from Silverlight

- by Torbjörn Josefsson

(Using Visual Studio 2008, and Silverlight 3) -I've really looked around for this one, and now I'm just confused by all the solutions that simply won't work for me. I'm trying to call a WCF service from a Silverlight client, which is no problem, but I can't get the service to handle sessions (I want to remember a few things about the callee between calls) I've gathered that basicHttpBinding is no good for sessions, and I haven't managed to make wsHttpBinding work... what's the matter? I would have thought this was a pretty basic thing people would want in their WCF services, or am I just completely muddle-headed not to see how it can be done?

Preventing RSI (Repetitive Strain Injuries)

- by nightcracker

I am 16 years old and I love to program and playing the piano. It's not uncommon that I'm bashing away on my mouse and keyboard all day long. I do not feel any pains doing so. Yet I am still worried, because I often hear from people that they can never type for longer then 10 minutes again without getting severe pains. Given my two hobbies, programming and playing the piano that worries me a lot. My current situation is this: G15 keyboard and G5 mouse A chair that looks like this (the back of the chair is surprisingly supportive): http://www.ikea.com/nl/nl/images/products/torbjorn-bureaustoel__0084333_PE210956_S4.JPG In my "normal sitting position" the table is around the height of my bellybutton. A LG Flatron L194wt screen (too small IMO, getting a new one soon) Should I be worrying about RSI/similar health issues? If yes, what can/should I do about it?
