5,732,436 | 0 | ISerializable and DataContract <p>Using WCF In Silverlight services, typically we want to use the DataContract and Datamember attributes to opt into what we want to have serialized. This is what we send to and from the client. For most things this has never been a problem.</p> <p>However, I have a few classes I am trying to share with my silverlight app, 'mature' classes, that I would like to send to the client full of data. These classes implement ISerializable which, doesn't like to play nice with the WCF service when I update.</p> <p>I need to leave the ISerializable attribute on there because it is being used else where is some older code. Currently the way I see it is my best option being to have a new class to transfer the data through, if at all possible I would prefer not to have to write a class just for transfering the data but I am thinking that is what I am going to have to do.</p> <p>Any Ideas on what I could do to get this to serialize through a service and still be able to keep the ISerializable tag on there?</p> |

12,766,011 | 0 | A Better Way To Make My Parallel.ForEach Thread Safe? <p>I would like to make the following code thread-safe. Unfortunately, I have tried locking at various levels within this code with no success. The only instance I can seem to achieve thread-safety is to place a lock around the entire loop which effectively makes the Parallel.ForEach no faster (possibly even slower) than just using foreach. The code is relatively/almost safe with no locking. It only seems to show slight variations in the summation of the geneTokens.Value[-1] keys and gtCandidates.Value[-1] keys about once out of every 20 or so executions. </p> <p>I realize that Dictionary is not thread-safe. However, I cannot change this particular object to a ConcurrentDictionary without taking a major performance hit downstream. I would rather run this part of the code with a regular foreach than change that particular object. However, I am using ConcurrentDictionary to hold the individual Dictionary objects. I have also tried making this change, and it does not solve my race issue.</p> <p><strong>Here are my Class level variables:</strong> </p> <pre><code>//Holds all tokens derived from each sequence chunk public static ConcurrentBag<sequenceItem> tokenBag = new ConcurrentBag<sequenceItem>(); public BlockingCollection<sequenceItem> sequenceTokens = new BlockingCollection<sequenceItem>(tokenBag); public ConcurrentDictionary<string, int> categories = new ConcurrentDictionary<string, int>(); public ConcurrentDictionary<int, Dictionary<int, int>> gtStartingFrequencies = new ConcurrentDictionary<int, Dictionary<int, int>>(); public ConcurrentDictionary<string, Dictionary<int, int>> gtCandidates = new ConcurrentDictionary<string, Dictionary<int, int>>(); public ConcurrentDictionary<string, Dictionary<int, int>> geneTokens = new ConcurrentDictionary<string, Dictionary<int, int>>(); </code></pre> <p><strong>Here is the Parallel.ForEach:</strong></p> <pre><code>Parallel.ForEach(sequenceTokens.GetConsumingEnumerable(), seqToken => { lock (locker) { //Check to see if the Sequence Token is a Gene Token Dictionary<int, int> geneTokenFreqs; if (geneTokens.TryGetValue(seqToken.text, out geneTokenFreqs)) { //The Sequence Token is a Gene Token *****************Race Issue Seems To Occur Here**************************** //Increment or create category frequencies for each category provided int frequency; foreach (int category in seqToken.categories) { if (geneTokenFreqs.TryGetValue(category, out frequency)) { //increment the category frequency, if it already exists frequency++; geneTokenFreqs[category] = frequency; } else { //Create the category frequency, if it does not exist geneTokenFreqs.Add(category, 1); } } //Update the frequencies total [-1] by the total # of categories incremented. geneTokenFreqs[-1] += seqToken.categories.Length; ****************************************************************************** } else { //The Sequence Token is NOT yet a Gene Token //Check to see if the Sequence Token is a Gene Token Candidate yet Dictionary<int, int> candidateTokenFreqs; if (gtCandidates.TryGetValue(seqToken.text, out candidateTokenFreqs)) { *****************Race Issue Seems To Occur Here**************************** //Increment or create category frequencies for each category provided int frequency; foreach (int category in seqToken.categories) { if (candidateTokenFreqs.TryGetValue(category, out frequency)) { //increment the category frequency, if it already exists frequency++; candidateTokenFreqs[category] = frequency; } else { //Create the category frequency, if it does not exist candidateTokenFreqs.Add(category, 1); } } //Update the frequencies total [-1] by the total # of categories incremented. candidateTokenFreqs[-1] += seqToken.categories.Length; ***************************************************************************** //Only update the candidate sequence count once per sequence if (candidateTokenFreqs[-3] != seqToken.sequenceId) { candidateTokenFreqs[-3] = seqToken.sequenceId; candidateTokenFreqs[-2]++; //Promote the Token Candidate to a Gene Token, if it has been found >= //the user defined candidateThreshold if (candidateTokenFreqs[-2] >= candidateThreshold) { Dictionary<int, int> deletedCandidate; gtCandidates.TryRemove(seqToken.text, out deletedCandidate); geneTokens.TryAdd(seqToken.text, candidateTokenFreqs); } } } else { //create a new token candidate frequencies dictionary by making //a copy of the default dictionary from gtCandidates.TryAdd(seqToken.text, new Dictionary<int, int>(gtStartingFrequencies[seqToken.sequenceId])); } } } }); </code></pre> |

27,712,919 | 1 | SQLAlchemy: order_by(None) for joinedload subclause queries? <p>We are using SQLAlchemy 0.9.8 on Python 2.7.7 and Postgres 9.3.</p> <p>We have a query that uses joinedloads to fully populate some Recipe objects using a single query. The query creates a large SQL statement that takes 20 seconds to execute - too long. Here's the <a href="http://pastebin.com/raw.php?i=ETNDAeAa" rel="nofollow">rendered SQL statement on Pastebin</a>. </p> <p>The rendered SQL has an ORDER BY clause that Postgres explain says is the source of 99% of the time spent on this query. This appears to come from the relationship in the ORM model, which has an order_by clause.</p> <p>However, we don't care about the order the results are returned for this query - we only care about the order when looking at a single object. If I remove the ORDER BY clause at the end of the rendered SQL statement, the query executes in less than a second - perfect.</p> <p>We tried using .order_by(None) on the query, but that seems to have no effect. The ORDER BY seems to be related to the joinedloads, because if change the joinedloads to lazyloads, they go away. But we need the joinedloads for speed.</p> <p>How can I get SQLAlchemy to omit the ORDER BY clauses? </p> <hr> <p>FYI, here's the query:</p> <pre><code>missing_recipes = cls.query(session).filter(Recipe.id.in_(missing_recipe_ids)) if missing_recipe_ids else [] </code></pre> <p>Here's an excerpt from the ORM class:</p> <pre><code>class Recipe(Base, TransactionalIdMixin, TableCacheMixin, TableCreatedModifiedMixin): __tablename__ = 'recipes' authors = relationship('RecipeAuthor', cascade=OrmCommonClass.OwnedChildCascadeOptions, single_parent=True, lazy='joined', order_by='RecipeAuthor.order', backref='recipe') scanned_photos = relationship(ScannedPhoto, backref='recipe', order_by="ScannedPhoto.position") utensils = relationship(CookingUtensil, secondary=lambda: recipe_cooking_utensils_table) utensil_labels = association_proxy('utensils', 'name') </code></pre> <p>Our query() method looks something like this (some more joinedloads omitted):</p> <pre><code>@classmethod def query(cls, session): query = query.options( joinedload(cls.ingredients).joinedload(RecipeIngredient.ingredient), joinedload(cls.instructions), joinedload(cls.scanned_photos), joinedload(cls.tags), joinedload(cls.authors), ) </code></pre> |

In this setup your application source code is kept in src/main/java, application resources, including properties files, in src/main/resources, and other config files in src/main/config. Files related to unit tests use a similar directory structure; src/test/java and src/test/resources.</p> <p>Personally I tend to use this layout because of its widespread use. I also keep an "etc" directory beneath the project root to house files that aren't directly related to the application. For example, I keep configuration files for PMD and Checkstyle in etc.</p> |

4,287,997 | 0 | <p>The most obvious tool would be SQL Profiler. It will monitor every SQL statement, and thus every data change, that gets sent to the server and show you metrics about that statement, the account under which the statement was executed and a host of other pieces of information and it comes free with most SQL Server versions. If you only want to see data changes, you can add filters to only show Insert, Update and Delete statements.</p> <p>If what you are trying to do is compare two databases to see what data is different between them, then I'd recommend something like Red-Gate's Data Compare (no I do not work for them).

Compare:</p> <pre><code>'{}-{}-{}'.format(year, starting_month, starting_day) </code></pre> <p>to what you have.</p></li> <li>You <em>have</em> the answer commented out - <code>print((d1-d2).days * 24 * 60)</code>. Just change that up: <code>print((date1-date2).days)</code></li> <li><p>You could actually just use math here:</p> <pre><code>pills_left = initial_pill_count - (daily_intake * number_of_days) </code></pre></li> </ul> <p>Putting this all together, here's how you should have written this:</p> <pre><code>from datetime import datetime # Just convert to int when you get the input. Also, only one space # before input. leftover_pill_count = int(input('How many pills do you have left? ')) new_pill_count = int(input('How many pills did you get? ')) daily_pill_intake = int(input('How many pills do you take every day? ')) # And one space before input! start_date = input('Starting date (YYYY-MM-DD): ') end_date = input('End date (YYYY-MM-DD): ') # Using the same format multiple places? Use a variable! # that way you only have to change it once :) date_fmt = '%Y-%m-%d' start_date = datetime.strptime(start_date, date_fmt) end_date = datetime.strptime(end_date, date_fmt) # `end-start`, always. Or you could use `abs(start-end)`, # but don't do that. total_days = (end_date-start_date).days initial_pill_count = leftover_pill_count + new_pill_count # Here's how the loop *should* look loop_pills_left = initial_pill_count for i in range(total_days): loop_pills_left -= daily_pill_intake print(loop_pills_left) # Or you could approach it mathematically! math_end_count = initial_pill_count - (daily_pill_intake * total_days) # Let's just make sure that both approaches get us the same answer, though assert math_end_count == loop_pills_left, 'If this fails, we got our math wrong' pills_left = loop_pills_left # String formatting is *much* nicer than concatenation. print('Taking {} pills per day you should have {} pills left.' .format(daily_pill_intake, pills_left)) </code></pre> |

When the user accesses a particular wifi network, I'd like the app to be launched automatically.</p> <p>How can this be accomplished? Would you recommend to use an Android Service that is running in the background to launch the app? Does the Android Service run in the background at all times?

36,749,392 | 0 | Using VBA To Delete Thousands of Checkboxes <p>Somehow 10s of thousands of checkboxes were created in some spreadsheets that we have. I'm not sure how this happened but we cannot open the sheets in Excel 2010 only in Excel 2003 because of it. I wrote some VBA script to go through and delete the extra checkboxes and it works for most of the files. But, some files seem to have way more checkboxes than others and the script dies with an Out of Memory error. This is my script:</p> <pre><code>Sub ProcessFiles() Dim Filename, Pathname, LogFileName As String Dim wb As Workbook Dim fso As Object Set fso = CreateObject("Scripting.FileSystemObject") Set log = fso.OpenTextFile("Z:\Temp\Fix.log", 8, True, 0) PrintLog ("*** Beginning Processing ***") Pathname = "Z:\Temp\Temp\" Filename = Dir(Pathname & "*.xls") Do While Filename <> "" PrintLog ("Opening " & Pathname & Filename) Set wb = Workbooks.Open(Pathname & Filename) DoWork wb PrintLog ("Saving file " & Pathname & Filename) wb.Close SaveChanges:=True Filename = Dir() Loop log.Close End Sub Sub DoWork(wb As Workbook) Dim chk As CheckBox Dim c As Integer With wb Worksheets("Vessel & Voyage Information").Activate PrintLog ("Getting count of checkboxes") c = ActiveSheet.CheckBoxes.Count PrintLog (c & " checkboxes found") If (c <= 43) Then PrintLog ("Correct # of checkboxes.

I am guessing that calling <code>ActiveSheet.CheckBoxes</code> gathers up all the checkboxes and there are too many so it dies.</p> <p>Is there a way to step through each checkbox on a worksheet without using <code>ActiveSheet.CheckBoxes</code>?</p> |

24,864,680 | 0 | iOS UITableView contents not visible <p>In a VC I have 2 tableViews - 1 main and other is added in a drop down menu. From drop down menu TableView "<code>ddTableView</code>", I have added 5 <code>cells</code> in Storyboard itself as prototype cells.

Have also set Accessory Type as "Disclosure Indicator" for each <code>cell</code> of <code>ddTableView</code>. </p> <p>DataSource and Delegate for mainTV is set to the VC and delegate for ddTableView is set the VC. As the rows are added within the storyboard, I didn't set any datasource for <code>ddTableView</code> in my <code>VC</code>.

UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath]; NSLog(@"CELL Identifier = %@", cell.reuseIdentifier); return cell; } else { } } -(void )tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { if (tableView == ddTableView) { UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath]; NSLog (@" CELL Clicked of - %@", cell.reuseIdentifier); } } -(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { if (tableView == ddTableView) return 44; else return 60; } -(NSInteger) tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { if (tableView == ddTableView) return 5; else return [chatMsgsArr count]; } </code></pre> <p>It does call respective delegate method.

These can go multiple levels deep, or just two levels (a Recordset contining Chapter fields) as in your request:</p> <blockquote> <p>Regardless of which way the parent Recordset is formed, it will contain a chapter column that is used to relate it to a child Recordset. If you wish, the parent Recordset may also have columns that contain aggregates (SUM, MIN, MAX, and so on) over the child rows. Both the parent and the child Recordset may have columns which contain an expression on the row in the Recordset, as well as columns which are new and initially empty.</p> <p>You can nest hierarchical Recordset objects to any depth (that is, create child Recordset objects of child Recordset objects, and so on).</p> <p>You can access the Recordset components of the shaped Recordset programmatically or through an appropriate visual control.</p> </blockquote> <p>The key to this is using the Data Shaping Service, an OLEDB Provider which "rides on top of" your underlying Provider (even if only the local Cursor Service Provider <em>implied</em> when using client-side cursors).</p> <p>Some description and a crude example can be found in the <a href="http://support.microsoft.com/kb/196029" rel="nofollow">How To Create Hierarchical Recordsets Programmatically</a> Support article.</p> <p>More details and reference material can be found at <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/ms676186%28v=vs.85%29.aspx" rel="nofollow">Data Shaping</a>, including the SQL-like language used to define Shape commands.</p> <hr> <p>Or are you asking about <em>paged</em> Recordsets, as in <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/ms681431%28v=vs.85%29.aspx" rel="nofollow">PageSize Property (ADO)</a> instead?</p> |

For example, I want to take the parameters from a 7x7x512 filter in Caffe and port it into MATLAB for use as a convolutional filter there. This way, rather than requiring me to run the network to delve into the filters being learned, I can use MATLAB to view the responses on my images. (In my case, this is preferable because I am running my Caffe network on a server with limited graphics while I have MATLAB on my local machine.)</p> |

19,515,477 | 0 | angular-ui datepicker does not allow format dd.MM.yyyy when entered into the input field <p>I think the best way to describe this problem is to steer you to the Plunk:</p> <p><a href="http://plnkr.co/edit/cRO5UgAyZx5SHJSKrzg7?p=preview" rel="nofollow">http://plnkr.co/edit/cRO5UgAyZx5SHJSKrzg7?p=preview</a></p> <p>The angular-ui datepicker doesn't like us Europeans! Start by selecting a date in the datepicker. Let's say it's the 25th October (at least the day should be greater than 12). You see that the datepick-format has been set to dd.MM.yyyy and this is relfected in the date set in the input field. Now change the year. This is not shown in the datepicker. However, if you enter the date in the format MM.dd.yyyy, all is well.</p> <p>I've added the angular-locale_de-de.js, which seems to be working as can be seen in the spelling of Oktober. So why can't I enter a date in the European [correct-and-logical-day-before-month] format?</p> |

3,763,480 | 0 | <p>You're defining the same function signature many times. The different <code>throw()</code> qualifiers are not enough to disambiguate the functions.</p> <p>The <code>throw()</code> qualifier simply means that the specified function is only expected to throw the types listed in the parenthesis following the qualifier. However, this does not actually prevent the function from throwing. Rather, if the function actually <em>does</em> throw any unlisted types, your program will terminate. </p> |

People "still stuck inside the Windows programming world" are generally using SourceSafe, or perhaps something really expensive like ClearCase.</p> <p>Subversion was developed with the goal of being a functional replacement for CVS, a goal which it pretty much succeeds at. Its probably OK to still use CVS if you are working an old project that already has CVS history. However, if you have a choice you should use SVN instead.</p> <p>That being said, you still at the end of the day are stuck with something built around CVS's workflow. The latest generation of revision control systems are much different. For instance, <a href="http://en.wikipedia.org/wiki/Distributed_revision_control" rel="nofollow noreferrer">distributed revision control systems</a> have far better tools for anyone who might ever have to access sources remotely (does your company have branch sites?) </p> |
