  • info about intel Cos embedded i86 os

    - by Tim Williscroft
    I've got some old Intel printer (Etherexpress XL ) print servers and they seem to be running an Intel OS called Cos aka Intel Client Os i86 I've found out that much just looking in the update files from Intel. It was at least partly written in C. How do I make a custom software image Intel Cos's boot loader will understand ? I know a host PC xmodem's the image to the client device, and I was wondering if anyone had already either reverse-engineered this or had original info ? or is my only recousre to reverse engineer the update file format ?

  • Concatenating Strings in Obj C

    - by eco_bach
    Hi It seems that Objective C jumps thru hoops to make seemingly simple tasks extremely difficult. I simply need to create a sequence of strings, image1.jpg, image2.jpg, etc etc ie in a loop var imgString:String='image'+i+'.jpg; I assume a best practice is to use a NSMutableString with appendString method? What am I doing wrong?? NSMutableString *imgString; for(int i=1;i<=NUMIMAGES;i++){ imgString.appendString(@"image"+i+@".jpg"); } I get the following error error: request for member 'appendString' in something not a structure or union

  • Performing periodic audits and best practice

    - by DTown
    I'm doing a windows form and would like an audit task to happen every 30 seconds. This audit is essentially checking a series of services on remote computers and reporting back into a richtextbox the status. Current I have this running in an endless background thread and using an invoker to update the richtextbox in the main form. Is this best practice? If I made an endless loop in my main form that would prevent any of my buttons from working, correct? I'm just curious if every time I want to create a periodic audit check I have to create a new thread which checks the status or file or what have you?

  • Sorting 2 arrays that have been added together

    - by tyler
    In my app, users can create galleries that their work may or may not be in. Users have and belong to many Galleries, and each gallery has a 'creator' that is designated by the gallery's user_id field. So to get the 5 latest galleries a user is in, I can do something like: included_in = @user.galleries.order('created_at DESC').uniq.first(5) # SELECT DISTINCT "galleries".* FROM "galleries" INNER JOIN "galleries_users" ON "galleries"."id" = "galleries_users"."gallery_id" WHERE "galleries_users"."user_id" = 10 ORDER BY created_at DESC LIMIT 5 and to get the 5 latest galleries they've created, I can do: created = Gallery.where(user_id: id).order('created_at DESC').uniq.first(5) # SELECT DISTINCT "galleries".* FROM "galleries" WHERE "galleries"."user_id" = 10 ORDER BY created_at DESC LIMIT 5 I want to display these two together, so that it's the 5 latest galleries that they've created OR they're in. Something like the equivalent of: (included_in + created).order('created_at DESC').uniq.first(5) Does anyone know how to construct an efficient query or post-query loop that does this?

  • Can't seem to be able to set ListViewItem.imageIndex

    - by TKL
    I have been scratching my head with this error for at least an hour, what the heck is wrong here? In a loop: if (selectedItems[x].ImageIndex == 3) { List<ListViewItem> dupes = CP.listCache.FindAll(delegate(ListViewItem item) { return item.Text == selectedItems[x].Text; }); if (dupes != null && dupes.Count == 1) dupes[0].ImageIndex = 0; } I can access the imageIndex, but not set it. ArgumentOutOfRange exception occurs.

  • jquery specific show buttons on hover

    - by bob
    I have an application creating a bunch of divs through a loop. Each div has the class "product" so it looks like <div class="product"> !.....stuff here ....! <div class="show_on_hover">...buttons here... </div> </div> so there are about 12 of these same divs per page. I would like to hover over a specific one and show the specific "show_on_hover" div which is initially set to display:none. $('.product').hover(function() { $(.show_on_hover).show(); }, function () { $(.show_on_hover).hide(); } ); That is what I have so far but it will show ALL of the .show_on_hovers on the page so I am wondering how to get only the specific one you have moused over to show. This effect is seen on youtube when you mouseover any of the comments, and some comment tools pop up. Thanks!

  • How can I declare classes that refer to each other?

    - by Without me Its just Aweso
    It's been a long time since I've done C++ and I'm running into some trouble with classes referencing each other. Right now I have something like: a.h class a { public: a(); bool skeletonfunc(b temp); }; b.h class b { public: b(); bool skeletonfunc(a temp); }; Since each one needs a reference to the other, I've found I can't do a #include of each other at the top or I end up in a weird loop of sorts with the includes. So how can I make it so that a can use b and vice versa without making a cyclical #include problem? thanks!

  • Write set of integers to std::ofstream and be able to read them back

    - by bndu
    Hello, I need to write a bunch of unsigned integers to std::ofstream in binary mode: std::ofstream f; f.open("some path", std::ios::out | std::ios::binary); // some loop { unsigned int k = get_k(); // may product numbers from 0 to 65535 f << k; } f.close(); They are written to the output file "as is" w/o any delimiter. So when I'm trying to read them back (expecting to get what I wrote) using std::ifstream I get very strange values. What I'm doing wrong? Or I should to put ' ' (space) to the stream after any added number to separate them? Thanks.

  • What can't the NDK be used for?

    - by Android Eve
    From the official NDK site: The Android NDK... provides headers and libraries that allow you to build activities, handle user input, use hardware sensors, access application resources, and more, when programming in C or C++. If you write native code, your applications are still packaged into an .apk file and they still run inside of a virtual machine on the device. The fundamental Android application model does not change. Yet, it is always described as a companion tool to the Android SDK and as a toolset that allows to "implement parts of your applications using native-code languages such as C and C++". My understanding from this is that, unlike the Java based SDK, the NDK is not designed to implement certain parts of an Android application. Is this correct? If so, what parts doesn't the NDK allow implementing?

  • I need to count the lines from matching config file entries, preferably with 'grep'.

    - by Chris
    I have a configuration file that has entries for various devices, with each entry separated by a blank line. I need to search the file for all instances of a given device type, and count the number of non-blank lines following the occurrence, stopping at the first blank. For example: Server=foo config line 1 config line 2 config line 3 Server=bar config line 1 config line 2 Server=foo config line 1 If I wanted to know how many total "config lines" were associated with server "foo", I should get four. Can you please help?

  • How to combine two arrays of same length to one array with two fields (not append/merge)

    - by Raj
    Say, I have an array with months $months = array('Jan', 'Feb', 'Mar'...'Dec'); And another, with days (say, for year 2010) $mdays = array(31, 28, 31...31); I want to merge/combine these two arrays, into an array like this: $monthdetails[0] = ('month' => 'Jan', 'days' => 31) $monthdetails[1] = ('month' => 'Feb', 'days' => 28) ... $monthdetails[11] = ('month' => 'Dec', 'days' => 31) I can loop through both the arrays and fill the $monthdetails. I want to know whether there are any functions/easier way for achieving the same result. Thanks! Raj

  • Development Applications on big devices vs mobile phones: Similarities/Disimilarities

    - by Richard77
    Hello, I saw a news document on applications running in mobile devices. And, I believe that might be interesting for people where I live (Internet is not developed - but the cellphone networks are much better). So here are my questions: Where can I find documentation for beginners on that matter (And most importantly) Am I gonna be able to take advantage of acquired knowledge in .NET framework (C#, MVC, JQuery, XHTML, ...)? Am I gonna need my laptop or a special device to develop applications? Am I gonna need Visual Studio? And so on... Bref, What are similarities/dissimilarities between developments for applications running in big machines and those running on mobile phones? Thanks for helping

  • Can you help me refactor this piece of clojure code to produce a seq?

    - by ique
    I want to produce a seq that I can later do a (map) over. It should look like this: ((0 0) (0 1) (0 2) (0 3) ... (7 7)) The piece of code I have to do it right now seems very, very ugly to produce such a simple result. I need some help getting this straight. (loop [y 0 x 0 args (list)] (if (and (= y 7) (= x 7)) (reverse (conj args (list y x))) (if (= x 7) (recur (+ y 1) 0 (conj args (list y x))) (recur y (+ x 1) (conj args (list y x))))))

  • How to find which method makes my iPhone app slow ?

    - by Stewart Hou
    Currently I am working on a production app. One function acts like the settings.app on iPhone. When the user click a cell of a tableView, as shown below http://www.penguintech.net/images/stackoverflow/1.png It will push another view, which includes a textfield to let user input something. However, on both simulator and device, after the app just loaded, the delay between clicking and showing the second view takes around 2 seconds. Then if user get back to previous view and click again, it will be no delay at all. To detect which method makes the delay, I put a NSLog() in every involved methods, but when I was inspecting the console while running the app, all NSLog() message showed in 0.1 seconds, and then still a delay on the app. Is there any other way to trace the performance footage of a app? The Instruments shows only CPU usage in Mac OS not in iPhone.

  • high tweet status IDs causing failed to open stream errors?

    - by escarp
    Erg. Starting in the past few days high tweet IDs (at least, it appears it's ID related, but I suppose it could be some recent change in the api returns) are breaking my code. At first I tried passing the ID as a string instead of an integer to this function, and I thought this worked, but in reality it was just the process of uploading the file from my end. In short, a php script generates these function calls, and when it does so, they fail. If I download the php file the call is generated into, delete the server copy and re-upload the exact same file without changing it, it works fine. Does anyone know what could be causing this behavior? Below is what I suspect to be the most important part of the individual files that are pulling the errors. Each of the files is named for a status ID (e.g. the below file is named 12058543656.php) <?php require "singlePost.php"; SinglePost(12058543656) ?> Here's the code that writes the above files: $postFileName = $single_post_id.".php"; if(!file_exists($postFileName)){ $created_at_full = date("l, F jS, Y", strtotime($postRow[postdate])-(18000)); $postFileHandle = fopen($postFileName, 'w+'); fwrite($postFileHandle, '<html> <head> <title><?php $thisTITLE = "escarp | A brief poem or short story by '.$authorname.' on '.$created_at_full.'"; echo $thisTITLE;?></title><META NAME="Description" CONTENT="This brief poem or short story, by '.$authorname.', was published on '.$created_at_full.'"> <?php include("head.php");?> To receive other poems or short stories like this one from <a href=http://twitter.com/escarp>escarp</a> on your cellphone, <a href=http://twitter.com/signup>create</a> and/or <a href=http://twitter.com/devices>associate</a> a Twitter account with your cellphone</a>, follow <a href=http://twitter.com/escarp>us</a>, and turn device updates on. <pre><?php require "singlePost.php"; SinglePost("'.$single_post_id.'") ?> </div></div></pre><?php include("foot.php");?> </body> </html>'); fclose($postFileHandle);} $postcounter++; } I can post more if you don't see anything here, but there are several files involved and I'm trying to avoid dumping tons of irrelevant code.

  • C++: static function member shared between threads, can block all?

    - by mhambra
    Hi all, I have a class, which has static function defined to work with C-style extern C { static void callback(foo bar) { } }. // static is defined in header. Three objects (each in separate pthread) are instantiated from this class, each of them has own loop (in class constructor), which can receive the callback. The pointer to function is passed as: x = init_function(h, queue_id, &callback, NULL); while(1) { loop_function(x); } So each thread has the same pointer to &callback. Callback function can block for minutes. Each thread object, excluding the one which got the blocking callback, can call callback again. If the callback function exists only once, then any thread attempting to callback will also block. This would give me an undesired bug, circa is interesting to ask: can anything in C++ become acting this way? Maybe, due to extern { } or some pointer usage?

  • Best practice to avoid InvalidOperationException: Collection was modified?

    - by Roflcoptr
    Very often I need something like that: foreach (Line line in lines) { if (line.FullfilsCertainConditions()) { lines.Remove(line) } } This does not work, because I always get a InvalidOperationException because the Enumerator was changed during the loop. So I changed all my loops of this kind to the following: List<Line> remove = new List<Line>(); foreach (Line line in lines) { if (line.FullfilsCertainConditions()) { remove.Add(line) } } foreach (Line line in remove) { { lines.Remove(line); } I'm not sure if this is really the best way since in the worst case I have to iterate 2 times over the original list and so it needs time 2n instead of n. Is there a better way to do this?

  • DOS Batch file - Copy file based on filename elements

    - by user1848356
    I need to sort alot of files based on their filename. I would like to use a batch file to do it. I do know what I want but I am not sure of the correct syntax. Example of filenames I work with: (They are all in the same directory originally) 2012_W34_Sales_Store001.pdf 2012_W34_Sales_Store002.pdf 2012_W34_Sales_Store003.pdf 2012_November_Sales_Store001.pdf 2012_November_Sales_Store002.pdf 2012_November_Sales_Store003.pdf I would like to extract the information that are located between the "_" signs and put them into a different variable each time. The lenght of the informations contained between the _ signs will be different everytime. Example: var1="2012" var2="W34" (or November) var3="Sales" var4="001" If I am able to do this, I could then copy the files to the appropriate directory using move %var1%_%var2%_%var3%_%var4%.pdf z:\%var3%\%var4%\%var1%\%var2% It would need to loop because I have Store001 to Store050. Also, there are not only Sales report, many others are available. I hope I am clear. Please help me realize this batchfile!

  • How do I use the orientationchange in jQuery Mobile when working with height?

    - by stucktryingtofigurethisout
    In jQuery Mobile, I am trying to adjust the height of an image to the height of the window. The height of the window depends on the orientation of the device, but I found out that whenever I change the orientation, the height of the window that is plugged into the expressions for the height of the image is the height of the window BEFORE the orientation change! So, how do I make it so it picks up the height of the window AFTER the orientation change and then uses this new value to adjust the image height? For the code I have $(window).bind('orientationchange',function(e){ if(window.orientation == 0) { $('img').css('width') = $(window).height()*.5; } else { $('img').css('width') = $(window).height()*.6; } });

  • using arrays to get best memory alignment and cache use, is it necessary?

    - by Alberto Toglia
    I'm all about performance these days cause I'm developing my first game engine. I'm no c++ expert but after some research I discovered the importance of the cache and the memory alignment. Basically what I found is that it is recommended to have memory well aligned specially if you need to access them together, for example in a loop. Now, In my project I'm doing my Game Object Manager, and I was thinking to have an array of GameObjects references. meaning I would have the actual memory of my objects one after the other. static const size_t MaxNumberGameObjects = 20; GameObject mGameObjects[MaxNumberGameObjects]; But, as I will be having a list of components per object -Component based design- (Mesh, RigidBody, Transformation, etc), will I be gaining something with the array at all? Anyway, I have seen some people just using a simple std::map for storing game objects. So what do you guys think? Am I better off using a pure component model?

  • PHP IF statement not taking variable into account!

    - by Jess
    I have a tabled view in a while loop, where a user can view information on books. For example, book ISBN, book name, read status... Basically, when the user sets their 'readstatus' to 'complete' I want that specific table row to become grey! The logic is very straight forward, however I can't get my IF statement to recognise this: $readstatus = $_GET['readstatus']; if ($readstatus == 'complete') { echo '<tr class="completed">'; } else if ($readstatus != 'complete') { echo '<tr class="reading">'; } I'm obviously doing something wrong here, but all I need is the CSS class of the table row to change if the value of 'readstatus' = 'complete', if not, then output the default CSS table row color ('reading') Should I be putting $result as the variable or something? I have this coming just before my nested IF statement: $result = mysql_query($sql, $connection) or die ("Couldn't perform query $sql <br />".mysql_error()); while($row = mysql_fetch_array($result)) { ?>
