  • Pygame program that can get keyboard input with caps

    - by None
    I have a Pygame program that needs text input. The way it does this is to get keyboard input and when a key is pressed it renders that key so it is added to the screen. Essentially it acts like a text field. The problem is, when you hold shift it doesn't do anything. I relize this is because the program ignores shift input and instead writes the text if it's number is under 128. I have thought of setting a variable when shift is pressed then capitalizing if it was true, but string capitalization only woks on letters, not things like numbers or semicolons. Is there maybe a number I can add to the ascii number typed to modify it if shift is pressed, or something else?

  • Can I force window to open on top of other windows when opened by keyboard shortcut?

    - by Rasmus
    I use SpaceFM as my primary file manager on Ubuntu. I typically open folder directly by keyboard shortcuts, so, e.g. Ctrl+Super+W opens my Work folder. Specifically, I use execute the command spacefm -w /home/rasmus/Work/ by the above shortcut, with the -w ensuring that SpaceFM opens a new window. However, this new window is not always open on top of the last active window on the workspace. This is rather annoying, as it means I sometimes have to "dig" for the newly opened window. So, my question is: Is there something additional I can add to the executed command that will ensure that the fresh window is opened on top? Alternative solutions to the same effect are welcome.

  • Is there a name for a language feature that allows assignment/creation?

    - by Alex Mcp
    This is a bit hard for me to articulate, but in PHP you can say something like: $myArray['someindex'] = "my string"; and if there is no index named that, it will create/assign the value, and if there IS an index, it will overwrite the existing value. Compare this to Javascript where today I had to do checks like so: if (!myObject[key]) myObject[key] = "value"; I know this may be a bit of a picky point, but is there a name for the ability of PHP (and many other languages) to do these checks on their own as opposed to the more verbose (read: PITA) method of Javascript?

  • Maximized Office 2007 gets cut off on multi-monitor setup with different resolutions

    - by Adam M-W
    I've got an external monitor plugged into my laptop that I like to use for typing up documents, but I've noticed that when Word is maximized it gets cut off at where the primary monitor's bounds are. Is this a bug in Wine (i'm using version 1.3.32), or with my Window Manager (metacity with compositing enabled, version 2.34.1), with my graphics drivers (nouveau) or something else? I know that I can fix it by unmaximizing (it doesn't get cut off and I can resize to the entirety of the second monitor), but it keeps on maximizing itself as it (rightly so) knows that it should be taking up the entire screen. I don't really want to use the "Emulate a virtual desktop feature", I would prefer to find the source of this issue.

  • Preventing Users From Copying Text From and Pasting It Into TextBoxes

    Many websites that support user accounts require users to enter an email address as part of the registration process. This email address is then used as the primary communication channel with the user. For instance, if the user forgets her password a new one can be generated and emailed to the address on file. But what if, when registering, a user enters an incorrect email address? Perhaps the user meant to enter <code>[email protected]</code>, but accidentally transposed the first two letters, entering <code>[email protected]</code>. How can such typos be prevented?The only foolproof way to ensure that the user's entered email address is valid is to send them a validation email upon registering that includes a link that, when visited, activates their account. (This

  • can't publish my asp.net project?

    - by Sulaiman
    dears, when try to publish my mroject I get this error: Error 3 Task failed because "AL.exe" was not found, or the correct Microsoft Windows SDK is not installed. The task is looking for "AL.exe" in the "bin" subdirectory beneath the location specified in the InstallationFolder value of the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SDKs\Windows\v6.0A. You may be able to solve the problem by doing one of the following: 1) Install the Microsoft Windows SDK for Windows Server 2008 and .NET Framework 3.5. 2) Install Visual Studio 2008. 3) Manually set the above registry key to the correct location. 4) Pass the correct location into the "ToolPath" parameter of the task.

  • quantity of measurable units design pattern

    - by Berryl
    Hello I am thinking through a nice pattern to be useful across domains of measurable units (ie, Length, Time) and came up with the following use case and initial classes, and of course, questions! 1) Does a Composite pattern help or complicate? 2) Should the Convert method(s) in the ComposityNode be a separate converter class? All comments appreciated. Cheers, Berryl Example Use Case: var inch = new ConvertableUnit("inch", 1) var foot = new ConvertableUnit("foot", 12) var imperialUnits = new CompositeConvertableUnit("imperial units", .024) imperialUnits.AddChild(inch) imperialUnits.AddChild(foot) var meter = new ConvertableUnit("meter", 1) var millimeter = new ConvertableUnit("millimeter ", .001) var imperialUnits = new CompositeConvertableUnit("metric units", 1) imperialUnits.AddChild(meter) imperialUnits.AddChild(millimeter) var oneInch = new Quantity(1, inch); var oneFoot = new Quantity(1, foot); oneFoot.ToBase() // "12 inches" var oneMeter = new Quantity(1, meter); oneInch.ToBase() // .024 meters Possible Solution ConvertableUnit : Node double Rate string Name Quantity ConvertableUnit Unit double Amount CompositeConvertableUnit : Node ISet<ConvertableUnit> _children ConvertableUnit BaseUnit {get{ return _children.Where(c=>c.Rate == 1).First() } } Quantity ConvertTo(Quantity from, Quantity to) Quantity ToBase(Quantity from);

  • C# or .Net features to cut off assuming no backward compatibility needed?

    - by Gulshan
    Any product or framework evolves. Mainly it's done to catch up the needs of it's users, leverage new computing powers and simply make it better. Sometimes the primary design goal also changes with the product. C# or .net framework is no exception. As we see, the present day 4th version is very much different comparing with the first one. But thing comes as a barricade to this evolution- backward compatibility. In most of frameworks/products there are features would have been cut off if there was no need to support backward compatibility. According to you, what are these features in C#/.net? Please mention one feature per answer.

  • Doubt about django model API

    - by Clash
    Hello guys! So, here is what I want to do. I have a model Staff, that has a foreign key to the User model. I also have a model Match that has a foreign key to the User model. I want to select how much Matches every Staff has. I don't know how to do that, so far I only got it working for the User model. From Staff, it will not allow to annonate Match. This is what is working right now User.objects.annotate(ammount=Count("match")).filter(Q(ammount__gt=0)).order_by("ammount") And this is what I wanted to do Staff.objects.annotate(ammount=Count("match")).filter(Q(ammount__gt=0)).order_by("ammount") And by the way, is there any way to filter the matches? I want to filter the matches by a certain column. Thanks a lot in advance!

  • retrieving information from web service calls

    - by Monte Chan
    Hi all, I am trying to retrieve information from a web service call. The following is what I have so far. In my text view, it is showing Map {item=anyType{key=TestKey; value=2;}; item=anyType{key=TestField; value=adsfasd; };} When I ran that in the debugger, I can see the information above in the variable, tempvar. But the question is, how do I retrieve the information (i.e. the actual values of "key" and "value" in each of the array positions)? Yes, I know there is a lot going on in onCreate and I will fix it later. Thanks in advance, Monte My codes are as follows, import java.util.Vector; import android.app.Activity; import android.os.Bundle; import android.widget.TextView; import org.ksoap2.SoapEnvelope; import org.ksoap2.serialization.SoapObject; import org.ksoap2.serialization.SoapSerializationEnvelope; import org.ksoap2.transport.AndroidHttpTransport; public class ViewHitUpActivity extends Activity { private static final String SOAP_ACTION = "test_function"; private static final String METHOD_NAME = "test_function"; private static final String NAMESPACE = "http://www.monteandjanicechan.com/"; private static final String URL = "http://www.monteandjanicechan.com/ws/test_ws.cfc?wsdl"; // private Object resultRequestSOAP = null; private TextView tv; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); tv = (TextView)findViewById(R.id.people_view); //SoapObject request.addProperty("test_item", "1"); SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); envelope.setOutputSoapObject(request); AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(URL); try { androidHttpTransport.call(SOAP_ACTION, envelope); /* resultRequestSOAP = envelope.getResponse(); Vector tempResult = (Vector) resultRequestSOAP("test_functionReturn"); */ SoapObject resultsRequestSOAP = (SoapObject) envelope.bodyIn; Vector tempResult = (Vector) resultsRequestSOAP.getProperty("test_functionReturn"); int testsize = tempResult.size(); // SoapObject test = (SoapObject) tempResult.get(0); //String[] results = (String[]) resultRequestSOAP; Object tempvar = tempResult.elementAt(1); tv.setText(tempvar.toString()); } catch (Exception aE) { aE.printStackTrace (); tv.setText(aE.getClass().getName() + ": " + aE.getMessage()); } } }

  • Creating SQL Server index on a nvarchar column

    - by Jahan
    When I run this SQL statement: CREATE UNIQUE INDEX WordsIndex ON Words (Word ASC); I get the following exception message: The CREATE UNIQUE INDEX statement terminated because a duplicate key was found for the object name 'dbo.Words' and the index name 'WordsIndex'. The duplicate key value is (ass). The statement has been terminated. The 'Word' column has a datatype of nvarchar(100). There are two items in the 'Word' column that SQL Server interprets as the same: 'aß' and 'ass', which causes the indexing failure. Why would SQL Server interpret those two different words as the same word?

  • Is there anything else I can do to optimize this MySQL query?

    - by Legend
    I have two tables, Table A with 700,000 entries and Table B with 600,000 entries. The structure is as follows: Table A: +-----------+---------------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +-----------+---------------------+------+-----+---------+----------------+ | id | bigint(20) unsigned | NO | PRI | NULL | auto_increment | | number | bigint(20) unsigned | YES | | NULL | | +-----------+---------------------+------+-----+---------+----------------+ Table B: +-------------+---------------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +-------------+---------------------+------+-----+---------+----------------+ | id | bigint(20) unsigned | NO | PRI | NULL | auto_increment | | number_s | bigint(20) unsigned | YES | MUL | NULL | | | number_e | bigint(20) unsigned | YES | MUL | NULL | | | source | varchar(50) | YES | | NULL | | +-------------+---------------------+------+-----+---------+----------------+ I am trying to find if any of the values in Table A are present in Table B using the following code: $sql = "SELECT number from TableA"; $result = mysql_query($sql) or die(mysql_error()); while($row = mysql_fetch_assoc($result)) { $number = $row['number']; $sql = "SELECT source, count(source) FROM TableB WHERE number_s < $number AND number_e > $number GROUP BY source"; $re = mysql_query($sql) or die(mysql_error); while($ro = mysql_fetch_array($re)) { echo $number."\t".$ro[0]."\t".$ro[1]."\n"; } } I was hoping that the query would go fast but then for some reason, it isn't terrible fast. My explain on the select (with a particular value of "number") gives me the following: mysql> explain SELECT source, count(source) FROM TableB WHERE number_s < 1812194440 AND number_e > 1812194440 GROUP BY source; +----+-------------+------------+------+-------------------------+------+---------+------+--------+----------------------------------------------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+------------+------+-------------------------+------+---------+------+--------+----------------------------------------------+ | 1 | SIMPLE | TableB | ALL | number_s,number_e | NULL | NULL | NULL | 696325 | Using where; Using temporary; Using filesort | +----+-------------+------------+------+-------------------------+------+---------+------+--------+----------------------------------------------+ 1 row in set (0.00 sec) Is there any optimization that I can squeeze out of this? I tried writing a stored procedure for the same task but it doesn't even seem to work in the first place... It doesn't give any syntax errors... I tried running it for a day and it was still running which felt odd. CREATE PROCEDURE Filter() Begin DECLARE number BIGINT UNSIGNED; DECLARE x INT; DECLARE done INT DEFAULT 0; DECLARE cur1 CURSOR FOR SELECT number FROM TableA; DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1; CREATE TEMPORARY TABLE IF NOT EXISTS Flags(number bigint unsigned, count int(11)); OPEN cur1; hist_loop: LOOP FETCH cur1 INTO number; SELECT count(*) from TableB WHERE number_s < number AND number_e > number INTO x; IF done = 1 THEN LEAVE hist_loop; END IF; IF x IS NOT NULL AND x>0 THEN INSERT INTO Flags(number, count) VALUES(number, x); END IF; END LOOP hist_loop; CLOSE cur1; END

  • How many questions is it appropriate to ask as an intern?

    - by Casey Patton
    So, I just started an internship, and I'm worried that I'm asking too many questions. My mentor assigns me projects and helps me learn all the company's technologies and methodologies. However, there's so much new material for me to learn while doing this project that I have a lot of questions. I generally ask questions over instant messages or E-mail (those are the primary modes of communication for my company). I'm trying to be careful not to ask too many questions: I don't want to come off as annoying or dumb. How many questions are appropriate to ask? Once an hour? More? Less? Keep in mind, my mentor is also a fellow programmer who has his own responsibilities.

  • Does semi-normalization exist as a concept? Is it "normalized"?

    - by Gracchus
    If you don't mind, a tldr on my experience: My experience tldr I have an application that's heavily dependent upon uncertainty, a bane to database design. I tried to normalize it as best as I could according to the capabilities of my database of choice, but a "simple" query took 50ms to read. Nosql appeals to me, but I can't trust myself with it, and besides, normalization has cut down my debugging time immensely over and over. Instead of 100% normalization, I made semi-redundant 1:1 tables with very wide primary keys and equivalent foreign keys. Read times dropped to a few ms, and write times barely degraded. The semi-normalized point Given this reality, that anyone who's tried to rely upon views of fully normalized data is aware of, is this concept codified? Is it as simple as having wide unique and foreign keys, or are there any hidden secrets to this technique? Or is uncertainty merely a special case that has extremely limited application and can be left on the ash heap?

  • MySQL + MyISAM table size question

    - by alessandro ferrucci
    Hello, I have a test table. The test table is as follows: CREATE TABLE mytest ( num1 int(10) unsigned NOT NULL, KEY key1 (num1) ) ENGINE=MyISAM DEFAULT CHARSET=latin1; I inserted 50 million rows in this table. When I do show table status the avg_row_length is 7. I was expecting to see 4 since mySQL uses 4 bytes for integers. Does the key have an effect on the avg_row_length? When I look at my .MYD file the size is 334 MB which is exactly what it should be given that the avg_row_length is 7, however I was really expecting to see 190 MB given that I only have an int. +----------------+--------+---------+------------+----------+----------------+-------------+------------------+--------------+-----------+----------------+---------------------+---------------------+------------+-------------------+----------+----------------+---------+ | Name | Engine | Version | Row_format | Rows | Avg_row_length | Data_length | Max_data_length | Index_length | Data_free | Auto_increment | Create_time | Update_time | Check_time | Collation | Checksum | Create_options | Comment | +----------------+--------+---------+------------+----------+----------------+-------------+------------------+--------------+-----------+----------------+---------------------+---------------------+------------+-------------------+----------+----------------+---------+ | mytest | MyISAM | 10 | Fixed | 50000000 | 7 | 350000000 | 1970324836974591 | 600518656 | 0 | NULL | 2010-05-22 09:15:06 | 2010-05-22 19:32:53 | NULL | latin1_swedish_ci | NULL | | | I have included the output of show table status for mytest table.

  • handling a GET error properly

    - by Andrew Heath
    I have a website that takes two primary get strings: ?type=GAME&id=SomeGameID ?type=SCENARIO&id=SomeScenarioID for reasons unknown, I have recently begun receiving requests for erroneous get strings from both Yandex and Baidu. They are always in the form of: ?type=GAME&id=SomeScenarioID None of my users are triggering these errors, so I am (sort of) confident that this is not due to an HTML template error somewhere on my part. There is also no HTTP_REFER showing up in the $_SERVER array, so I'm guessing these are direct requests from bad dbase data on their part. I see two options for dealing with these bad requests, and would like to know which is recommended... or if there are other, better options I have not thought of: simply 404 the request, since it is incorrect redirect the request to ?type=SCENARIO&id=SomeScenarioID because the scenario IDs are always valid, the breakage is due to asking for the wrong type.

  • What's the best way to move to linux from windows for web development ?

    I am primarily a programmer developing on windows based OS using c# as my primary language. I am evaluating Ubuntu Linux as an alternate platform and would like to know the best stack for doing web development on this. I had gone through the following thread Moving development from Windows to Linux but it doesn't answer my questions fully. Some of the points I am interested are outlined below PHP/Ruby/Python (What would you recommend?) Is Mono mature enough for any large scale development? Has anyone any real experience using Mono. IDE (including debugging support, intellisense, source control integration,Unit testing) Unit testing framework based on the language recommended Web framework if any. Load Testing tools Web server (I know there are many webservers, but would like to know which one is primarily used by most people) Your inputs is greatly appreciated. Thanks.

  • Good Literature for "Object oriented programming in C"

    - by Dipan Mehta
    This is not a debate question about whether or not C is a good candidate for Object oriented programming or not. Quite often C is the primary platform where the development is happening. I have seen, and hopefully learnt through crawling many open source and commercial projects - that while the language inherently doesn't stop you if you create "non-object" code. However, you can still think in the "Object" way and reasonably write code that captures this designs thinking. For those who has done this, OO way is still the best way to write code even when you are programming in C. While, I have learnt most of it through the hard way, are there any deep literature that can help educate the relatively young guys about how to do OO programming in C?

  • Does google contribute ranking from cdn.example.com to example.com?

    - by DesignerGuy
    Background From my understanding, http://mywebsite.com/image.jpg, can help the ranking of http://mywebsite.com in a search engine, such as Google (obviously the search engine of primary concern). So, SEO-wise, moving an image to http://whatever-cdn.com/my-account/image.jpg is bad. A popular solution is to use a CNAME record, such as http://cdn.mywebsite.com, so that image.jpg can be accessed at http://cdn.mywebsite.com/image.jpg. The question Does http://cdn.mywebsite.com/image.jpg rank as effectively as http://mywebsite.com/image.jpg ? Does it help boost the main http://mywebsite.com ? Or, does it rank independently because it is a subdomain? Is there another option (a way to use a CDN without sacrificing ranking)?

  • How do i supress keypress being printed to console in .NET?

    Hello, I'm porting a small C++ console game to C# and it seems that I can't stop key presses from being printed to the console. In C++ I get the keystroke with this method, which also suppress the keystrokes from being printed to the console: bool Game::getInput(char *c) { if (_kbhit()) { *c = _getch(); return true; } return false; } I tried to do the equivalent in C# by doing: Key = Console.ReadKey(); But this does not suppress the character from being printed to the console, causing obvious problems. Any ideas on how to remedy this?

  • Slime in emacs seems has conflicts with autopair

    - by Boris
    I have just install slime in emacs. And after removed all the other plugins for debuging, I found that slime seems had conflicts with autopair.(Or a bug of autopair?).In slime, when I typed C-c C-c, the minibuffer displayed error like: error in process filter: define-key: Wrong type argument: characterp, nil error in process filter: Wrong type argument: characterp, nil error in process filter: define-key: Wrong type argument: characterp, nil error in process filter: Wrong type argument: characterp, nil Even more, the error message still alerted after I killed the slime buffer. If I also remove the autopair plugin, slime works just fine. Can anyone tell me how to solve this? Thanks. :)
