  • extremely small gap between two divs that are width 100%

    - by Naomi K
    hi I have two container divs one of them has a div with an image background and i think this is the div that is causing problem. I tried removing both container divs and the gap was still here. there are no margins no paddings, and i know it is not the image that has this line its not there when i open it in photoshop. I am also using css reset Where is this space coming from? css .container{ width:100%; } .container2{ width:100%; } .first-image{ width:1430px; height:497px; background-image:url('../images/introimg.jpg'); background-repeat:no-repeat; background-size: 100%; border:none; } .jamey{ width:35%; } .second-image{ width:1430px; height:430px; background-image:url('../images/secondimg.jpg'); background-repeat:no-repeat; background-size: 100%; } html <div class="container"> <div class="wrapper"> <div id="overlay"></div> <div class="first-image"> <div class="jamey"> <p class="def"> JAMEY </p> <p class="rip-date">03.02.1997 - 09.18.2011</p> <p class="def2">Anonymous hate messages were posted on his Formspring account including one that claimed:</p> </div> </div> </div> </div> <div class="container2"> <div class="intro-div"> <div class="end-hate"> <h1>PUT AN END TO HATE.</h1> <p> ANYTHING WRITTEN ONLINE can become viral </p> <p> We believe that the way we behave online should be no different from the way that we behave in </p> <button type="button">JOIN CAMPAIGN</button> </div> </div>

  • Most efficient method to query a Young Tableau

    - by Matthieu M.
    A Young Tableau is a 2D matrix A of dimensions M*N such that: i,j in [0,M)x[0,N): for each p in (i,M), A[i,j] <= A[p,j] for each q in (j,N), A[i,j] <= A[i,q] That is, it's sorted row-wise and column-wise. Since it may contain less than M*N numbers, the bottom-right values might be represented either as missing or using (in algorithm theory) infinity to denote their absence. Now the (elementary) question: how to check if a given number is contained in the Young Tableau ? Well, it's trivial to produce an algorithm in O(M*N) time of course, but what's interesting is that it is very easy to provide an algorithm in O(M+N) time: Bottom-Left search: Let x be the number we look for, initialize i,j as M-1, 0 (bottom left corner) If x == A[i,j], return true If x < A[i,j], then if i is 0, return false else decrement i and go to 2. Else, if j is N-1, return false else increment j This algorithm does not make more than M+N moves. The correctness is left as an exercise. It is possible though to obtain a better asymptotic runtime. Pivot Search: Let x be the number we look for, initialize i,j as floor(M/2), floor(N/2) If x == A[i,j], return true If x < A[i,j], search (recursively) in A[0:i-1, 0:j-1], A[i:M-1, 0:j-1] and A[0:i-1, j:N-1] Else search (recursively) in A[i+1:M-1, 0:j], A[i+1:M-1, j+1:N-1] and A[0:i, j+1:N-1] This algorithm proceed by discarding one of the 4 quadrants at each iteration and running recursively on the 3 left (divide and conquer), the master theorem yields a complexity of O((N+M)**(log 3 / log 4)) which is better asymptotically. However, this is only a big-O estimation... So, here are the questions: Do you know (or can think of) an algorithm with a better asymptotical runtime ? Like introsort prove, sometimes it's worth switching algorithms depending on the input size or input topology... do you think it would be possible here ? For 2., I am notably thinking that for small size inputs, the bottom-left search should be faster because of its O(1) space requirement / lower constant term.

  • Change width of UIImageView

    - by BenMills
    How would you change just the width of a UIImageView in objective-c? Currently I'm doing this: imageview.frame = GCRectMake(x,y,width,height); But when I change the width it seems to just change the position rather then change the size.

  • Android - How to scan Access Points and select strongest signal?

    - by Donal Rafferty
    I am currently trying to write a class in Android that will Scan for access points, calculate which access point has the best signal and then connect to that access point. So the application will be able to scan on the move and attach to new access points on the go. I have the scanning and calculation of the best signal working. But when it comes to attaching to the best access point I am having trouble. It appears that enableNetwork(netid, othersTrueFalse) is the only method for attaching to an Access point but this causes problems as from my Scan Results I am not able to get the id of the access point with the strongest signal. This is my code: public void doWifiScan(){ scanTask = new TimerTask() { public void run() { handler.post(new Runnable() { public void run() { sResults = wifiManager.scan(getBaseContext()); if(sResults!=null) Log.d("TIMER", "sResults count" + sResults.size()); ScanResult scan = wifiManager.calculateBestAP(sResults); wifiManager.addNewAccessPoint(scan); } }); }}; t.schedule(scanTask, 3000, 30000); } public ScanResult calculateBestAP(List<ScanResult> sResults){ ScanResult bestSignal = null; for (ScanResult result : sResults) { if (bestSignal == null || WifiManager.compareSignalLevel(bestSignal.level, result.level) < 0) bestSignal = result; } String message = String.format("%s networks found. %s is the strongest. %s is the bsid", sResults.size(), bestSignal.SSID, bestSignal.BSSID); Log.d("sResult", message); return bestSignal; } public void addNewAccessPoint(ScanResult scanResult){ WifiConfiguration wc = new WifiConfiguration(); wc.SSID = '\"' + scanResult.SSID + '\"'; //wc.preSharedKey = "\"password\""; wc.hiddenSSID = true; wc.status = WifiConfiguration.Status.ENABLED; wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP); wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP); wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK); wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP); wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP); wc.allowedProtocols.set(WifiConfiguration.Protocol.RSN); int res = mainWifi.addNetwork(wc); Log.d("WifiPreference", "add Network returned " + res ); boolean b = mainWifi.enableNetwork(res, false); Log.d("WifiPreference", "enableNetwork returned " + b ); } When I try to use addNewAccessPoint(ScanResult scanResult) it just adds another AP to the list in the settings application with the same name as the one with the best signal, so I end up with loads of duplicates and not actually attaching to them. Can anyone point me in the direction of a better solution?

  • GTK TextView automatically resizing

    - by endeavormac
    I'm messing around with GTK and glade for the first time, and I've run across a really annoying issue. When I enter text into a TextView, the TextView automatically resizes larger, pushing other widgets away. This is a really annoying behavior. I do not want my TextView changing size depending on the amount of text within it. Does anyone know what I can do to prevent the TextView from resizing based on its content?

  • Configure trace for SpringServer dm 2

    - by Eric J.
    According to the Spring documentation, By default, the dm Server trace file is called $SERVER_HOME/serviceability/logs/dm-server/log_i.log ... The index i varies from 1 to 4, on a rolling basis, as each log file exceeds 10Mb. I'm aware that the default trace file name can be changed in server.config. Is it possible to change the number of log files that are kept before rolling over and/or the maximum log file size? How?

  • Trying to populate ListView in Android using objects from Parse

    - by mrwienerdog
    I am pretty darned new to android, and VERY new to Parse. I have created a class, StudentInformation, that includes columns for name, address, phone, etc. I would like to create a listview that contains the names of all students added to the class. How do I do this? I have got it to the point that I can Toast out the objectIDs of all of my entries, but can't figure out how to extract and add just the names to the ListView. Here is a snippet of the code: //Set up the listview studentListView = (ListView)findViewById(R.id.listViewStudents); //Create and populate an ArrayList of objects from parse ParseQuery query = new ParseQuery("StudentInformation"); final ArrayList<Object> studentList = new ArrayList<Object>(); query.findInBackground(new FindCallback() { public void done(List<ParseObject> objects, ParseException e) { if (e == null) { Toast.makeText(getApplicationContext(), objects.toString(), Toast.LENGTH_LONG).show(); for(int i = 0;i < objects.size(); i++){ objects.get(i); studentList.add("name".toString()); } } else { Toast.makeText(getApplicationContext(), "Error", Toast.LENGTH_LONG).show(); } } }); //studentList.addAll(Arrays.asList(students)); listAdapter = new ArrayAdapter<Object>(this,android.R.layout.simple_list_item_1,studentList); studentListView.setAdapter(listAdapter); } I have left the toast in where I toatst out the objectIDs in the public void done.... method. Any help would be, as always, greatly appreciated. Should be mentioned (possibly), no errors are thrown, the listview just never gets populated after the toast disappears. Don't know if this will help anyone, but I took a bit from both posts below, and came up with this: //Set up the listview studentList = new ArrayList<String>(); //Create and populate an ArrayList of objects from parse listAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1); studentListView = (ListView)findViewById(R.id.listViewStudents); studentListView.setAdapter(listAdapter); final ParseQuery query = new ParseQuery("StudentInformation"); query.findInBackground(new FindCallback() { public void done(List<ParseObject> objects, ParseException e) { if (e == null) { //Toast.makeText(getApplicationContext(), objects.toString(), Toast.LENGTH_LONG).show(); for (int i = 0; i < objects.size(); i++) { Object object = objects.get(i); String name = ((ParseObject) object).getString("name").toString(); listAdapter.add(name); } } else { Toast.makeText(getApplicationContext(), "Error", Toast.LENGTH_LONG).show(); } } });

  • Binary socket and policy file in Flex

    - by Daniil
    Hi, I'm trying to evaluate whether Flex can access binary sockets. Seems that there's a class calles Socket (flex.net package). The requirement is that Flex will connect to a server serving binary data. It will then subscribe to data and receive the feed which it will interpret and display as a chart. I've never worked with Flex, my experience lies with Java, so everything is new to me. So I'm trying to quickly set something simple up. The Java server expects the following: DataInputStream in = ..... byte cmd = in.readByte(); int size = in.readByte(); byte[] buf = new byte[size]; in.readFully(buf); ... do some stuff and send binary data in something like out.writeByte(1); out.writeInt(10000); ... etc... Flex, needs to connect to a localhost:6666 do the handshake and read data. I got something like this: try { var socket:Socket = new Socket(); socket.connect('192.168.110.1', 9999); Alert.show('Connected.'); socket.writeByte(108); // 'l' socket.writeByte(115); // 's' socket.writeByte(4); socket.writeMultiByte('HHHH', 'ISO-8859-1'); socket.flush(); } catch (err:Error) { Alert.show(err.message + ": " + err.toString()); } The first thing is that Flex does a <policy-file-request/>. I've modified the server to respond with: <?xml version="1.0"?> <!DOCTYPE cross-domain-policy SYSTEM "/xml/dtds/cross-domain-policy.dtd"> <cross-domain-policy> <site-control permitted-cross-domain-policies="master-only"/> <allow-access-from domain="192.168.110.1" to-ports="*" /> </cross-domain-policy> After that - EOFException happens on the server and that's it. So the question is, am I approaching whole streaming data issue wrong when it comes to Flex? Am I sending the policy file wrong? Unfortunately, I can't seem to find a good solid example of how to do it. It seems to me that Flex can do binary Client-Server application, but I personally lack some basic knowledge when doing it. I'm using Flex 3.5 in IntelliJ IDEA IDE. Any help is appreciated. Thank you!
