Disk / memory problems with 10.6.4 ?

I have about 3.5 G free on my system partition. Sometimes, during the middle of use, the system becomes extremely slow. Around the same time, my HD space starts vanishing for no reason and I get a "Your Startup disk is almost full" message. A df -h reveals that I have perhaps 100M left (my apps are generating no large files). I am then forced to reboot (this happens about once a day). On the other hand, I find my installation of Matlab R2008_B no longer works. It launches X then nothing happens. All this started when I did the 10.6.4 update along with a bunch of Apple sec

onkeypress event in <input /> tag

Hi everybody, I have the following: . . . . . . . . . . . . . . . . . . <input type="text" name="capt_var" value=" " maxlength="10" onkeypress="keystroke()" /> . . . . . . . . . . . . . . . . . . The onkeypress clause calls keystroke function but, inside it, how can I retrieve the last key pressed, before it is appended to the variable being captured? Thanks in advance for your help. Regards, Marco

[9fans] native lbl, long text in troff, bold italics in eqn

Hello, I have basically 3 questions: 1) is there a native lbl (for symbolic labels in text documents), or do I have to grab the unix tarball and somehow compile that? (How? Using APE? Never tried that before...) 2) I heard and read that the 'ms' troff macros are not suitable for longer documents (I want to write my PhD thesis), as opposed supposedly to the 'me' macros (which, however are not in plan9, I believe). Can anybody give me their opinion? 3) Although eqn produces worse result than TeX, I like the way formulae are input, and thus have used it. Sometimes I need bold i

Problem compiling mex function

Hello, I am trying to compile a .mex file that grabs data from a National Instruments high-speed digitizer card. I have the code working on an older machine (32bit windows XP with Matlab 7.0.1), but am running into linker errors on a new machine (64bit windows 7 with 64bit Matlab 7.10.0). When I try to mex the .cpp file I get the following linker errors: mex('-v', ... '-LC:\Program Files (x86)\IVI Foundation\IVI\Lib\msc\', ... '-lniScope', '-livi','-liviscope', ...

Wanted images/unwanted logos in Eudora message bodies?

Occasionally I receive emails with images (JPEG, GIF, PDF) intentionally embedded and visible in the message text, rather than attached. These image files also show up in a default downloads folder I've set. This all seems to me a useful feature, and I like it. I have one organization with which I exchange a lot of email, however, who recently started including a couple of logo GIFs in all their messages. I think it's got to be some sort of template or default in the organization's email system, since the exact same logos are appearing in the messages from everyone in the o

Mountain.rb in Boulder Oct6-9 early bird closing Monday

Hi all, Just a quick note to anyone who doesn't know about this conf. I'm excited since it's up the way from me in Boulder and has a great speaker line up including Jim Weirich, Aaron Patterson and others on some really cool topics. Additional plus is that the country's largest Ignite - Boulder Ignite is happening one of the nights as well. There's more info on the site: http://mountainrb.com I just registered and realized the early bird ends on Monday for what looks to be a killer conference, figured I'd forward this on to the list. Look me up if you make it, I'm always up

Placing cursor in edit field in gui

Hi all. I'm trying to figure out how to place a cursor in a specific edit box automatically and my searches for the last 15 minutes haven't yielded fruitful results. Can somebody point me in the right direction?

unbound object frame woes

Sorry to repost. I need an unbound object frame to display varios objects including Word documents, Excel, PDFs, BMPs JPGs, DIBs, GIFs etc The word documents, Excel, PDFs, BMPs all seem fine, but I get a blank screen for the JPGs, DIBs, GIFs. If I double click on the blank screen I get an error message "The operation on the HTML Document failed" "The OLE Server may not be registered" Access 2010 Windows 7 Any ideas please

Concurrency Support in CL

Hi all, Before I got into Haskell programming a few years (4) ago I studied "Practical Common Lisp". I really enjoyed it and am looking to get back into the Lisp world. As a lot of my application development has become server development and so good support for persistent shared state and concurrency are important in choosing a Lisp. Clojure has addressed this need well which makes it a compelling choice, but I don't want to give up CLOS and the many other features that I liked about CL. Has there been any CL development in this space since I last left that make it competitive with Cl

3d plot with multiple 2d plot contours

I need to draw a 3d plot as follows: There are three planes that are parallel. on each plane I wish to draw a 2d plots like contours or multiple circles. I also want to draw the planes and draw arrows that connect the some points inside the planes.

blur matrix only

Hi, I did search this in this forum about blur matrix but looks no specific question and answer on creating a blur matrix of a square matrix. I don't want to use the imfilter which already blurred the image without I can access the blur matrix. For example, I also tried to generate the blur matrix, B from an image size 100x100 but the rows becomes greater than the columns, 10404 x 10000. How to create a square blur matrix of size NxN (e.g: 10000x10000) ? H = ones(3,3)/9; % averaging filter 3-by-3 B = convmtx2(H,r,c); %2D convolution matrix where r and c is the row and column for t

Problem with camera up vector (camup)

Hi all! I'm making a video from an image sequence in matlab from a 3d sequence of plots. I need to change the position of the camera for each plot, then save the image and create a video from the image sequence. The problem is that when I move the camera position, keeping the camera target fixed, I get a strange behavior: the plot seems to rotate! I tried to set the camera up vector, setting it to 0 0 1, in order to point the z axis to the top, but the rotation still persists, even if it is a bit smaller (i.e., if i plot an horizontal plane, the plane is rotate of around 60 degrees). Why the c

Turing Machine versus parallel programming

Turing specified the mathematical basis of single threaded programming. His machine was as a practical solution useless but it was a magnificent example of maths setting the basis of the whole concept of calculating computability. Has anyone actually asked a pure mathematician to try to produce a mathematical model for parallel computing. Ken Young

Love the netbook

Again while on holiday, I took my ASUS 4G Surf with me. Because of its compact size, it was an easy fit as airline carry on luggage. I left my Dell laptop home, which would have been considered as an additional item. Sent out several work related E-mails, browsed the net using the hotel's wifi. Kept track of my E-bay listings. All this under Ubuntu 9.10 Netbook Remix. Life is good. -- HPT

Find nonzero rows in matrx

Is there a simple method (or a function) that you can use to find nonzero rows in a matrix. So, suppose I have a matrix A: A = [ 1 0 0 2 3 5 0 4 3 1 0 5] Row 2 has only nonzero elements, while rows 1, 3 and 4 have some zero elements. I would nou like to get the index of the "nonzero row", which in this case is 2 of course. Can anyone help? Tanks!

Light-weight class redefinition semantics for CLOS.

There exists a very simple alternative to the current class redefinition semantics of CLOS that avoids all the thread-safety issues of the lazy instance updating feature mandated by the current specification. This alternative is simply to always create a completely new class object, that is a new instance of standard-class with a new identity, every time defclass is invoked. In this scheme there is no automatic updating of any instance outside the control of the application code. Any instance update has to be done under application control, at a time and in a context of its cho

R.U.S.E. demo out

Hi, http://store.steampowered.com/app/33310/ Copy & Paste of Arctic Blast's description of the game over at The Wargamer forum : "The 'gimmick' is the availability of various ruses in game. You earn them through battle results and the like, and can use them on a specific region in the game. Propaganda to reduce enemy morale, fake radio chatter and dummy units to create a feint, radio silence and camo to hide the real offensive, that sort of thing. The other part that's different is the scale. This isn't like CoH where you're micromanaging individual guys. You're sending out u

voronoin

Hello, I need to create the Voronoi Diagram of a group of kidney cells. I have centroid coordinates (3D) of every cells. I open the file (called 'Glomerulo') with the coordinates and then: x=Glomerulo(:,1); y=Glomerulo(:,2); z=Glomerulo(:,3); B=[x y z]; #creation of the centroids matrix [v, C]=voronoin(B) #3D voronoi diagram of B NOW: HOW CAN I PLOT MY DIAGRAM?

[9fans] pipefile.c in p9p

I downloaded Plan9port today, and found thewre is no pipefile. It's not good to me, because I need ktrans.=E2=98=BA Is it difficult to implement REGEND for p9p's rfork? Or anything other difficulties are there for pipefile.c? Kenji

find creation date of file

By using the dir function the "last change" date of a file is available in Matlab. However if I was interested in finding the "creation date" of the same file, how should/could I do that. perhaps this J-Script could be helpful? Though I am not so good at implementing Java in Matlab so someone maybe could help me turn this into Matlab: function ShowFileInfo(filespec) { var fso, f, s; fso = new ActiveXObject("Scripting.FileSystemObject"); f = fso.GetFile(filespec); s = "Created: " + f.DateCreated; return(s); } found at: http://msdn.microsoft.com/en-us/library/ke6a

BER performance with non-costant group delay filter

Hi, I'm trying to set up a Matlab simulation in order to see the effect of real analog base band filter on my receiver. If I use a FIR filter, I generally remove some samples equal to the filter group delay before sending the received vector to the demodulator. If I model a real filter, the group delay is not constant over frequency ( it can vary over the channel bandwidth too) and moreover it is not an integer number. How should I trim the filter output? Thanks Alberto
