34,573,787 | 0 | <p>Your second file - <code>captureit.java</code> - cannot be an Activity. An Activity can only be created by calling <code>startActivity()</code> or <code>startActivityForResult()</code> from another activity with an intent. When you call <code>new CaptureIt()</code> the <code>onCreate()</code> method and other activity-specific methods are not called. This means that the activity doesn't have the correct information to do some things - like starting another activity.</p> <p>Basically you're trying to start the camera activity from an activity that doesn't exist to Android, so it's throwing a NullPointerException.</p> <p>I'd recommend moving it back into the same file until you understand how moving between activities works in Android.</p> <p>You could still split the helper methods (<code>getOutputMediaFile()</code>, etc) into another file to keep the main activity file simple.

4,191,293 | 0 | <p>StringTokenizer treats consecutive delimiters as a single delimiter. You say the input contains [tab space] as delimiters, but the rest of your code doesn't seem to be expecting spaces so, without more information, I'm going to guess that the input is delimited only with tabs (not [tab space]), and the adjacent delimiters are being ignored, Then the last <code>nextToken()</code> throws an exception which you are ignoring.</p> <p>The answer here is to rewrite this using <code>split()</code>, as recommended in the <a href="http://download.oracle.com/javase/6/docs/api/java/util/StringTokenizer.html" rel="nofollow">Javadoc</a></p> <blockquote> <p>StringTokenizer is a legacy class that is retained for compatibility reasons although its use is discouraged in new code.

14,335,983 | 0 | <p>I used my apple developer support for this. Here's what the support said : </p> <blockquote> <p>The presence of the Voice I/O will result in the input/output being processed very differently. We don't expect these units to have the same gain levels at all, but the levels shouldn't be drastically off as it seems you indicate.</p> <p>That said, Core Audio engineering indicated that your results may be related to when the voice block is created it is is also affecting the RIO instance. Upon further discussion, Core Audio engineering it was felt that since you say the level difference is very drastic it therefore it would be good if you could file a bug with some recordings to highlight the level difference that you are hearing between voice I/O and remote I/O along with your test code so we can attempt to reproduce in house and see if this is indeed a bug. It would be a good idea to include the results of the singe IO unit tests outlined above as well as further comparative results.</p> <p>There is no API that controls this gain level, everything is internally setup by the OS depending on Audio Session Category (for example VPIO is expected to be used with PlayAndRecord always) and which IO unit has been setup. Generally it is not expected that both will be instantiated simultaneously.</p> </blockquote> <p>Conclusion? I think it's a bug. :/</p> |

33,938,334 | 0 | Weird SQL Server stored procedure behaviour - different results between asp.net and Management Studio <p>We have a stored procedure that’s used to populate a SSRS Report. It’s a bit of a monster – loads of conditional logic (in case statements), casts (sometimes embedded in other casts) from varchar to datetime, and 3 fields that rely on calls to a function that contains some date functions . The report contains financial information for a list of contracts for one organisation.</p> <p>I need to create an asp.net page that shows a subset of the data for one organisation/contract so I cloned the sproc and added a contract parameter. However I noticed the figures for the 3 fields that rely on the function are different on the web page from when the stored procedure is run directly on the database or through the report.</p> <p>To troubleshoot I created a page (quick and dirty using <code>SqlDataSource</code> and <code>DataGrid</code>) that shows the results of the original stored procedure showing all contracts. The query runs fine through Enterprise Manager but the web page crashes with the YSOD and the message </p> <blockquote> <p>The conversion of a nvarchar data type to a datetime data type resulted in an out-of-range value.</p> </blockquote> <p>I even tried hardcoding the SQL from the stored procedure into the web page but still get the same results</p> <p>On my dev machine the original stored procedure runs and my new stored procedure does return consistent results regardless of whether viewed through the web page or Management Studio. The regional settings etc are same on the dev server and live server. The only different thing I can think of is that the live web server and db server are on separate machines.</p> <p>Has anyone come across anything like this before??</p> <p>Thanks</p> |

And that is likely due to a general consensus that it's generally better to work with copies of everything expect objects. BUT--it is not slow like you might expect. PHP uses a lazy copy called copy on write, where it is really a read-only reference. On the first write, the copy is made.</p> <blockquote> <p>PHP uses a lazy-copy mechanism (also called copy-on-write) that does not actually create a copy of a variable until it is modified.</p> <p>Source: <a href="http://www.thedeveloperday.com/php-lazy-copy/" rel="nofollow">http://www.thedeveloperday.com/php-lazy-copy/</a></p> </blockquote> |

This has never been a problem because in our framework, as we've never expected an unwieldy number of columns in our tables.</p> <p>While the above code works, it's obvious that it's not a clean implementation and thus why I'm trying to refactor it into SQLAlchemy's cleaner, more robust ORM paradigm. I started going through SQLAlchemy's official tutorials and various examples and have arrived at the following code:</p> <pre><code>from sqlalchemy import Column, String, Integer from sqlalchemy.ext.declarative import declarative_base from sqlalchemy import create_engine from sqlalchemy.orm import sessionmaker Base = declarative_base() class Listing(Base): __tablename__ = 'Listings' id = Column(Integer, primary_key=True) make = Column(String) model = Column(String) year = Column(Integer) engine = create_engine('sqlite:///') session = sessionmaker() session.configure(bind=engine) Base.metadata.create_all(engine) data = {'make':'Chevy', 'model' : 'Corvette', 'year' : 1964} record = Listing(**data) s = session() s.add(record) s.commit() s.close() </code></pre> <p>and it works beautifully with that data dict. Now, when I add a new keyword, such as</p> <pre><code>data = {'make':'Chevy', 'model' : 'Corvette', 'year' : 1964, 'price' : 50000} </code></pre> <p>I get a <code>TypeError: 'price' is an invalid keyword argument for Listing</code> error. To try and solve the issue, I modified the class to be dynamic, too:</p> <pre><code>class Listing(Base): __tablename__ = 'Listings' id = Column(Integer, primary_key=True) make = Column(String) model = Column(String) year = Column(Integer) def __checker__(self, data): for i in data.keys(): if i not in [a for a in dir(self) if not a.startswith('__')]: if type(i) is int: setattr(self, i, Column(Integer)) else: setattr(self, i, Column(String)) else: self[i] = data[i] </code></pre> <p>But I quickly realized this would not work at all for several reasons, e.g. the class was already initialized, the data dict cannot be fed into the class without reinitializing it, it's a hack more than anything, et al.). The more I think about it, the less obvious the solution using SQLAlchemy seems to me. So, my main question is, <strong>how do I implement this level of dynamicism using SQLAlchemy?</strong></p> <p>I've researched a bit to see if anyone has a similar issue. The closest I've found was <a href="http://stackoverflow.com/questions/2768607/dynamic-class-creation-in-sqlalchemy">Dynamic Class Creation in SQLAlchemy</a> but it only talks about the constant attributes ("<strong>tablename</strong>" et al.). I believe the unanswered <a href="http://stackoverflow.com/questions/29105206/sqlalchemy-dynamic-attribute-change">SQLalchemy dynamic attribute change</a> may be asking the same question. While Python is not my forte, I consider myself a highly skilled programmer (C++ and JavaScript are my strongest languages) in the context scientific/engineering applications, so I may not hitting the correct Python-specific keywords in my searches.</p> <p>I welcome any and all help.</p> |
20,426,764 | 0 | <p>Quick suggestion add id as primary key column to users table. Then get that id after new record is inserted and save that id in SharedPreferences, then when ever required you can pull record from users table like using WHERE <code>id</code> = my_id_save.

12,458,198 | 1 | merging selenium rc and webdriver <p>I have made most of my automation code using Selenium RC with Python. But, I feel that with the evolution in my product (what I'm testing through selenium RC), my automation needs are changed. I tried Wedriver with python and it works a treat with my product. But, as many features of my new product versions are inherited from the previous versions, I feel that I can make use of my existing Selenium RC code. But, for new features, I want to use Webdriver.</p> <p>Moreover, there are also some things w.r.t the selenium profile that I 'm maintaining. Examples:</p> <ol> <li>For ssl certificates, using selenium RC, I have 2 methods: Selenium profile (where I have saved the acceptance of ssl certificate) and <code>'trustallsslcertificates'</code> parameter while starting selenium rc. Using <code>trustallsslcertificates</code> slows down the automation speed like hell.<br> But, using webdriver, I dont need all such ssl certificates.</li> <li>Using Selenium RC, whenever I need to download a file using my web page, I have used the save option as default and saved it in the same selenium profile. But, using webdriver, I have other options to download a file, rather than maintaining the selenium profile.</li> </ol> <p>I also checked in the existing question: <a href="http://stackoverflow.com/questions/4342088/selenium-web-driver-and-selenium-rc">Selenium Web driver and selenium RC</a>, but, the answer seems to old, many things must have updated by then. </p> <p>Crux of my question is: Can I integrate my existing python code, that I use using selenium RC (Python bindings - selenium.py ), with Webdriver using python ?</p> <p>PS: Currently I am using selenium 2.3.0.jar file</p> |

24,937,783 | 0 | <p>A good usage would be to implement a chunk to translate to-and from-base64 or any unaligned data structure.</p> <pre><code>struct { unsigned int e1:6; unsigned int e2:6; unsigned int e3:6; unsigned int e4:6; } base64enc; //I don't know if declaring a 4-byte array will have the same effect. struct { unsigned char d1; unsigned char d2; unsigned char d3; } base64dec; union base64chunk { struct base64enc enc; struct base64dec dec; }; base64chunk b64c; //you can assign 3 characters to b64c.enc, and get 4 0-63 codes from b64dec instantly. </code></pre> <p>This example is a bit naive, since base64 must also consider null-termination (i.e. a string which has not a length <code>l</code> so that <code>l</code> % 3 is 0). But works as a sample of accessing unaligned data structures.</p> <p>Another example: Using this feature to <strong>break a TCP packet header into its components</strong> (or other network protocol packet header you want to discuss), althought it is a more advanced and less end-user example. In general: this is useful regarding PC internals, SO, drivers, an encoding systems.</p> <p>Another example: analyzing a <code>float</code> number.</p> <pre><code>struct _FP32 { unsigned int sign:1; unsigned int exponent:8; unsigned int mantissa:23; } union FP32_t { _FP32 parts; float number; } </code></pre> <p>(Disclaimer: Don't know the file name / type name where this is applied, but in C this is declared in a header; Don't know how can this be done for 64-bit flaots since the mantissa must have 52bits and -in a 32bit target- ints have 32 bits).</p> <p><strong>Conclusion:</strong> As the concept and these examples show, this is a rarely used feature because it's mostly for internal purposes, and not for day-by-day software.</p> |

34,732,378 | 0 | Anyway to have programs share Windows Explorer icon overlays? <p>The fact that Windows only allows 15 icon overlays is well worn territory at this point. I understand how to rename the registry entries to get the overlays I absolutely <em>need</em> to be visible. But I wonder if there is a better way. </p> <p>I don't know much about registry editing and I know next to nothing about the inner working of windows and how the overlays actually get requested/delivered. So I'm not sure how these overlays actually work... But the programs I use that have overlays (TortoiseSvn, Box, Google Drive) all do basically the same thing. Generally speaking, they compare the status of a file locally to the status of a file in the cloud or on a server. For this reason it seems like many of these overlays could logically be shared. Why couldn't the BoxSynced, GoogleDriveSynced, and Tortoise1Normal all use the same icon?</p> <p>So my question is: Does anyone know of a way to manipulate the registry to combine some icon overlays? Or is there maybe a some sort of tool or utility out there that can achieve something like a set of "shared overlays"? </p> |

So I copy the jap entry that was inserted right from phpmyadmin or from my site where the jap is displayed and paste into a notepad i notice that it paste like this... (this is an exact paste into the below quotes)</p> <p>" </p> <p>バスにのって、うみへ行きました"</p> <p>and obviously i need, it without that white space and breaks or whatever it is.</p> <p>so as far as I can tell the trim is not doing what it says it will do. or im missing something here. if so what is it?</p> <p>UPDATE: with regards to Jacks answer</p> <p>the preg_replace did not help but here is what i did, i used the bin2hex() to determine that the part that "is not the part i want" is efbbbf i did this by taking $jap into str replace and removing the japanese i am expecting to find, and what is left goes into the bin2hex. and the result was the above "efbbbf"</p> <pre><code>echo bin2hex(str_replace("どちらがあなたの本ですか","",$jap)); </code></pre> <p>output of the above was efbbbf but what is it? can i make a str_replace to remove this somehow?</p> |
14,561,942 | 0 | <p>You could use sets for that, but a <code>dict</code> can not be added to a set unfortunately. You need to 'cast' the dictionaries to something that a set <em>can</em> handle, e.g. a immutable type such as a sequence of tuples. Combine that with an index to return the referenced <code>dict</code>:</p> <pre><code>def magicFunction(a, b): a = [tuple(sorted(d.items())) for d in a] b = [tuple(sorted(d.items())) for d in b] return [dict(kvs) for kvs in set(a).difference(b)] </code></pre> <p>Result:</p> <pre><code>>>> firstDict = [{'A':1 ,'B':1}, {'A':2 ,'B':2}] >>> secondDict = [{'A':3 ,'B':3}, {'A':2 ,'B':2}] >>> magicFunction(firstDict, secondDict) [{'A': 1, 'B': 1}] >>> magicFunction(secondDict, firstDict) [{'A': 3, 'B': 3}] </code></pre> |

10,179,303 | 0 | Accessing matrices stored inside of cell arrays using MEX files in MATLAB <p>I am currently writing a MEX function that will have to work with a cell array in MATLAB. The MEX file is written in C. </p> <p>Essentially, the input to my function will be a cell array where each entry is a numeric matrix with real values. A simple example is:</p> <pre><code>C = cell(1,2); C{1} = ones(10,10); C{2} = zeros(10,4); </code></pre> <p>I would like to be able to access the numeric arrays C{1} and C{2} in my MEX file. Ideally, I would like to do this without having to create a second copy of the data in my MEX File (i.e. get pointers for them).</p> <p>Using the previous example, my current approach is as follows:</p> <pre><code>/* declare a pointer variable to the incoming cell array after it is passed to the MEX function */ mxArray C_CELL = (mxArray *) mxGetData(prhs[0]) /* declare a 2 x 1 array of pointers to access the cell array in C */ double *myarray[2] // /* point towards the contents of C_CELL */ myarray[0] = mxGetPr(C_CELL[0]) myarray[1] = mxGetPr(C_CELL[1]) </code></pre> <p>Unfortunately this seems to yield "invalid use of undefined type 'struct mxArray_tag'" errors.</p> |

Without going into too much details, I have three files - file1.h, file2.cpp, and main.cpp</p> <ul> <li>file1.h contains the interface for a class</li> <li>file2.cpp includes file1.h and contains the class's member functions </li> <li>main.cpp includes file1.h</li> </ul> <p>So upon executing my program, I was very surprised that main.cpp had access to the functions inside file2.cpp, despite main only including file1.h.</p> <p>I don't think this is the best way to go about organizing the code, but it piqued my curiosity - how is it that I can access functions contained in file2.cpp from main.cpp, despite the fact that only file1.h is included in main.cpp?</p> <p>It would make sense to me if I had file2.cpp included in file1.h, but I don't.</p> <p><strong>I'm just curious how/why this works.

And everything after last dot after last backslash in string is interpreted as <em>file extension</em> even if this means that the folder or file name referenced with <code>%~n</code> is an empty string because the folder/file name starts with a dot and does not contain one more dot like many "hidden" files on *nix systems have, e.g. <code>.htaccess</code>. Therefore <code>%~nx</code> should be always used if entire name of a folder or file is needed on a command line.</p> |
