  • Inline comments for bash?

    - by Lajos Nagy
    I'd like to be able to comment out a single flag in a one-line command. Bash only seems to have `from # till end-of-line' comments. I'm looking at tricks like: ls -l $([ ] && -F is turned off) -a /etc It's ugly, but better than nothing. Anybody has any better suggestions?

    I'm currently running Xcode 3.2.2 on Snow Leopard. When opening Organizer Screenshots I see a list of screenshots I did before. But when I click the Capture button, nothing's happening.

  • Which mouse for preventing carpal tunnel/RSI symptoms?

    - by user102533
    I started getting carpal tunnel symptoms about a year back and have tried different mice/keyboards and nothing seems to help. When my right wrist (i am right handed) started giving me pain, I switched from a regular optical mouse to this logitech mouse: It helped for a short while. I then started to learn using my left hand to operate the mouse. Now, my left wrist has started experiencing the symptoms. Which mouse do you recommend that has really helped you?

  • jQuery jScrollPane - it simply won't work! :'(

    - by Jack Webb-Heller
    Hey folks, OK - I'll admit, I'm quite a beginner in this jQuery-department. I've probably made some amateur mistake, but hey, you gotta learn somewhere! :) So I'm using jScrollPane: http://www.kelvinluck.com/assets/jquery/jScrollPane/jScrollPane.html I want to use it style the scrollable area in my second column. Specifically, I would like to apply and format the scrollbars on the div #ajaxresults My page is... rather jQuery heavy. I don't know if any variables are conflicting or something... in fact I really have no idea at all why this isn't working. Take a look at my problematic page: http://furnace.howcode.com In the header, I've set this to go: <!-- Includes for jScrollPane --> <script type="text/javascript" src="http://localhost:8888/js/jquery.mousewheel.min.js"></script> <script type="text/javascript" src="http://localhost:8888/js/jScrollPane.js"></script> <link rel="stylesheet" type="text/css" media="all" href="http://localhost:8888/stylesheets/jScrollPane.css" /> <script type="text/javascript"> $(function() { $('#ajaxresults').jScrollPane(); }); </script> (I've changed localhost on the server copy though) Nothing ever seems to work with the #ajaxresults div. I've set, as the jScrollPane docs say, overflow:auto on it but still no luck. I find that when jScrollPane DOES seem to 'run' it just moves the div down about 100 pixels. Try it for yourself. Perhaps someone could help? There's quite a few jQuery plugins there so I don't know if something's colliding/crashing etc... Please note the site is still in development between myself and a friend, which explains the personal messages we submit to each other ('Hi Donnie!' etc. :D ). Also, when you view the page nothing may appear in the second column for a few seconds - it's just fetching the data via Ajax. So give it a little time. Thanks very much! Jack

  • How to get MinValue/MaxValue of a certain ValueType via reflection?

    - by marco.ragogna
    I need to this at runtime. I checked using Reflector and value types line like Int16, for example, should contain <Serializable, StructLayout(LayoutKind.Sequential), ComVisible(True)> _ Public Structure Int16 Implements IComparable, IFormattable, IConvertible, IComparable(Of Short), IEquatable(Of Short) Public Const MaxValue As Short = &H7FFF Public Const MinValue As Short = -32768 End Structure But the following code is not working Dim dummyValue = Activator.CreateInstance(GetType(UInt16)) Dim minValue As IComparable = DirectCast(dummyValue.GetType.GetProperty("MinValue").GetValue(dummyValue, Nothing), IComparable) any idea how to solve?

  • Add New Gist using the Github API

    - by Ben Shelock
    I'm making a small app in Adobe Air which I need to interact with the Github Gist API. However I'm kind of stuck. If you're not familiar with Adobe Air you can still help, the XMLHttpRequest javascript object can do cross domain requests, as there is no domain as such. So theres nothing Adobe Air specific here. Where I'm stuck is I think I need to authenticate myself then make the POST. I just don't understand it

  • GCD function in matlab

    - by SalemFayad
    hi, i am looking for a way to implement the "gcd" function used in matlab in another language but i really cant understand the way it functions. it says in http://www.mathworks.com/access/helpdesk/help/techdoc/ref/gcd.html that: "[G,C,D] = gcd(A,B) returns both the greatest common divisor array G, and the arrays C and D, which satisfy the equation: A(i).*C(i) + B(i).*D(i) = G(i)." but it says nothing about how it calculates C and D. i would be grateful if someone has a clearer idea about this subject! thanks:)

  • No norwegian characters in LaTeX

    - by DreamCodeR
    Hi, I have translated a document from English to Norwegian in the LaTeX format, and while using norwegian special characters, I get an error using \usepackage[utf8x]{inputenc} to try and display the norwegian (scandinavian) special characters in PostScript/PDF/DVI format, saying Package utf8x Error: MalformedUTF-8sequence. So while that didn't work, I tried out another possible solution: \usepackage{ucs} \usepackage[norsk]babel And when I tried to save that in Emacs I get this message: These default coding systems were tried to encode text in the buffer `lol.tex': (utf-8-unix (905 . 4194277) (916 . 4194245) (945 . 4194278) (950 . 4194277) (954 . 4194296) (990 . 4194277) (1010 . 4194277) (1013 . 4194278) (1051 . 4194277) (1078 . 4194296) (1105 . 4194296)) However, each of them encountered characters it couldn't encode: utf-8-unix cannot encode these: \345 \305 \346 \345 \370 \345 \345 \346 \345 \370 ... Thanks to Emacs I have the possibility to check out the properties of those characters and the first one tells me: character: \345 (4194277, #o17777745, #x3fffe5) preferred charset: eight-bit (Raw bytes 128-255) code point: 0xE5 syntax: w which means: word buffer code: #xE5 file code: not encodable by coding system utf-8-unix display: not encodable for terminal Which doesn't tell me much. When I try to build this with texi2dvi --dvipdf filename.text I get a perfectly fine PDF, all without the special norwegian characters. When I am about to save Emacs also ask me: "Select coding system (default raw-text):" And I type in utf-8 to choose its coding system. I have also tried to choose default raw-text to see if I get some different result. But nothing. At last I tried \lstset{inputencoding=utf8x, extendedchars=\true} ... a code I came over while trying to google the solution to this problem. Which gives me this error: Undefined control sequence. So basically, I have tried every encoding option I have been able to find and nothing works. I am desperately trying to make this work since the norwegian translation must be published before the deadline. As an additional information I may add that I found out later on that I only had the en_US.UTF-8 in my locale, so I added nb_NO.UTF-8 and nb_NO.ISO-8859-15 and ran locale-gen + reboot without any changes. I hope I provided enough information to get some assistance, the characters in question is æ ø å.

  • _heapwalk reports _HEAPBADNODE, causes breakpoint or loops endlessly

    - by Stefan Hubert
    I use _heapwalk to gather statistics about the Process' standard heap. Under certain circumstances i observe unexpected behaviours like: _HEAPBADNODE is returned some breakpoint is triggered inside _heapwalk, telling me the heap might got corrupted access violation inside _heapWalk. I saw different behaviours on different Computers. On one Windows XP 32 bit machine everything looked fine, whereas on two Windows XP 64 bit machines i saw the mentioned symptoms. I saw this behaviour only if LowFragmentationHeap was enabled. I played around a bit. I walked the heap several times right one after another inside my program. First time doing nothing in between the subsequent calls to _heapWalk (everything fine). Then again, this time doing some stuff (for gathering statistics) in between two subsequent calls to _heapWalk. Depending upon what I did there, I sometimes got the described symptoms. Here finally a question: What exactly is safe and what is not safe to do in between two subsequent calls to _heapWalk during a complete heap walk run? Naturally, i shall not manipulate the heap. Therefore i doublechecked that i don't call new and delete. However, my observation is that function calls with some parameter passing causes my heap walk run to fail already. I subsequently added function calls and increasing number of parameters passed to these. My feeling was two function calls with two paramters being passed did not work anymore. However I would like to know why. Any ideas why this does not happen on some machines? Any ideas why this only happens if LowFragmentationHeap is enabled? Sample Code finally: #include <malloc.h> void staticMethodB( int a, int b ) { } void staticMethodA( int a, int b, int c) { staticMethodB( 3, 6); return; } ... _HEAPINFO hinfo; hinfo._pentry = NULL; while( ( heapstatus = _heapwalk( &hinfo ) ) == _HEAPOK ) { //doing nothing here works fine //however if i call functions here with parameters, this causes //_HEAPBADNODE or something else staticMethodA( 3,4,5); } switch( heapstatus ) { ... case _HEAPBADNODE: assert( false ); /*ERROR - bad node in heap */ break; ...

  • Toggle iPhone tethering by code

    - by Canada Dev
    I live in Canada, so am fortunate that I can tether. One issue is that to toggle tethering, you need to drill down four screens in Settings, which is just a big hassle. A Google search returned nothing, so I was wondering if anyone here knew the code to turn on/off tethering? I know there's a toggle for SBSettings, but I do not have a jailbroken phone, I just want to create an app I build onto my phone and have an icon for quickly toggling it. Thanks

  • What is a python equivalent of PHP's var_dump()

    - by Zoredache
    When debugging in PHP I frequently find it useful to simply stick a var_dump($foo, $bar, ...) in my code to show me the the what a variable is, what is value is, and the same for anything that it contains. What is a good python equivalent for this? I have seen several things in my Google searching that are somewhat equivalent, but nothing that is the same or better.
