3,901,838 | 0 | <p>Usually, attaching a debugger would not slow down an application too much (compared to starting the application from the debugger, which will set the heap in debug mode).</p> <p>But by default, the debugger will trace events (exceptions and OutputDebugString), and in your case, there may be too much of them. After attaching with the debugger, you can disable all exception handling. (Menu Debug/Event Filters, or command sxi). You have to change the handling for all events (<code>sxi *</code> means unknown events, and does not apply to all events). You can also disable all tracing with <code>.outmask-0xFFFFFFFF</code>. Then enable only the stack overflow event with <code>sxe -c ".outmask /d" sov</code></p> |

10,518,402 | 0 | Validation with exceptions vs IDataErrorInfo and the new INotifyDataErrorInfo <p>I'm trying out different ways of validating and I'm having a problem with the new INotifyDataErrorInfo-interface.</p> <p>When writing in for instance a bound textbox that only accepts 10 chars. I write 11 chars and tab out. The validation kicks in and marks the textbox red etc. Now, I don't want to write this invalid value down to the source of this binding, but if I'm not doing this I immediately get the value in the textbox reset to the last valid value. It's as if the binding does an UpdateTarget on it's binding even though there was an error.</p> <p>By using ValidatesOnExceptions and throwing exception in the setter I get the behaviour I'm after. The binding is not updating it's value from the source if an exceptions has been thrown in the setter. This leaves the invalid value in the textbox so that I can work with it to make it valid. I think this is far better than having to store the invalid value in the underlying object.</p> <p>The question is why IDataErrorInfo and the new INotifyDataErrorInfo behaves in this way that it updates target from source even though there were errors? Can I make it to behave more like ValidatesOnExceptions?</p> <p>I need INotifyDataErrorInfo because of other features such as async validation...</p> |

With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive depending on the purpose of the photographic material and the method of processing. A negative image on film is traditionally used to photographically create a positive image on a paper base, known as a print, either by using an enlarger or by contact printing. </p> </div> <!--Responsive Video Slider and Title--> <div id="Recent-Projects"> <h1>Recent Projects</h1> </div> <div id="video-wrapper"> <span class="cycle-prev">&#9001</span> <span class="cycle-next">&#9002</span> <div class="cycle-slideshow" data-cycle-carousel-visible="3" data-cycle-fx="carousel" data-cycle-timeout="0" data-cycle-auto-height="640:360" data-cycle-prev=".cycle-prev" data-cycle-next=".cycle-next" data-cycle-slides=">iframe" data-cycle-youtube="true" data-cycle-youtube-autostart="true" data-cycle-pager=".cycle-pager" data-cycle-carousel-fluid="true" > <iframe width="560" height="315" src="https://www.youtube.com/embed/7TccWhZ6T8c?rel=0" frameborder="0" allowfullscreen></iframe> <iframe width="560" height="315" src="https://www.youtube.com/embed/VPuKbzP2KNM?rel=0" frameborder="0" allowfullscreen></iframe> <iframe width="560" height="315" src="https://www.youtube.com/embed/DHW0hQHLpTc?rel=0" frameborder="0" allowfullscreen></iframe> </div> <div class="cycle-pager"></div> </div> <!--End Responsive Video Slider and Title--> <script> (function() { var body = $('body'); $('.menu-toggle').bind('click', function() { body.toggleClass('menu-open', 'toggle-open'); return false; }); })(); </script> </code></pre> <p></p> <p> </p> <p>CSS</p> <pre><code>body { background-color:black; overflow:scroll; } /*Design for Slide Down menu*/ .menu { overflow:hidden; position:relative; top:0px; -webkit-transition: top 0.8s ease; -moz-transition: top 0.8s ease; transition: top 0.8s ease; } .menu-open { top:231px; } .menu-open .menu-side { top:0px; } .menu-side { background-color:#333; border-bottom:1px solid #000; color:#fff; position:fixed; top:-231px; left:0px; width: 100%; max-width:100%; height: 210px; padding: 10px; -webkit-transition: top 0.8s ease; -moz-transition: top 0.8s ease; transition: top 0.8s ease; } .menu-toggle { position:relative; display:block; width:50px; height:50px; margin-left:auto; margin-right:auto; top:-23.5px; } /*Content style for Menu Side*/ .menu-side ul { width:800px; max-width:100%; height:100px; display:block; text-align:center; margin-left:auto; margin-right:auto; border-style:solid; border-color:white; border-width:thick; -moz-box-shadow:20px 20px 20px 10px black; -webkit-box-shadow:10px 10px 10px 10px 10px black; box-shadow:1px 1px 20px 0.5px black; } .menu-side li { margin-top:auto; margin-bottom:auto; padding:10px; display:inline-block; text-align:center; font-family:Baskerville, "Palatino Linotype", Palatino, "Century Schoolbook L", "Times New Roman", serif; font-size:18px; font-style:italic; } /*Style for Josh Meyers About*/ #Josh-Meyers h1 { text-align:center; color:#FFF; } #Josh-Meyers p { color:#FFF; } /*Style for Video Slide Show and Title*/ #Recent-Projects { text-align:center; height:40px; width:100%; max-width:100%; } #Recent-Projects h1 { text-align:center; color:#FFF; } iframe {max-width:100%} #video-wrapper { width:100%; max-width:100%; height:400px; margin-top:5px; } .cycle-slideshow { width:100%; top:2%; margin-left:auto; max-width:90%; margin-right:auto; } .cycle-prev, .cycle-next { font-size:40px; font-weight:bold; color:#FFF; display:block; position:absolute; top:60%; z-index:999; cursor:pointer; } .cycle-prev {left:2%;} .cycle-next {right:2%;} .cycle-pager { text-align: center; width: 100%; z-index: 999; position: absolute; overflow: hidden; top:85% } .cycle-pager span { font-family: arial; font-size: 50px; width: 16px; height: 16px; display: inline-block; color: #ddd; cursor: pointer; } .cycle-pager span.cycle-pager-active { color: #D69746;} .cycle-pager > * { cursor: pointer;} iframe { padding-left:5px; padding-right:5px; } </code></pre> |

9,580,713 | 0 | Implementing a simple thread pool <p>I'm currently in the need of a simple and efficient thread pool implementation. I have searched here and also on Google and found numerous interesting links, but nothing i've found so far seems to be suitable. Most of the implementations i have found on the web are either too complicated or lack some of the key features i need.</p> <p>Also i don't want to use code that i do not understand, so i decided to code it myself (sometimes reinventing the wheel helps me push myself forward in terms of knowledge and experience). I of course understand the basic idea behind thread pool, but some implementation details are still somewhat unclear to me. This is probably because the kind of thread pool i need is a bit special. Let me describe it. I have a task that is done hundreds of thousands of times on a particular (large) buffer. I have measured that the performance is much better if I use threads for this task - the buffer is split into sub-buffers and each thread performs its task on the sub-buffer and returns the result. All the results from all threads are then added together, giving me the final solution.</p> <p>However since this is done very often i'm losing precious time because of so many threads being created (because of the overhead that comes with thread creation). So i would like to have a pool of threads that would perform this task, instead of creating a new set of threads every time.</p> <p>To be more clear, this is what i have so far:</p> <ul> <li>Split the buffer into N sub-buffers of the same size</li> <li>For each sub-buffer, create a thread and run it on the sub-buffer</li> <li>Wait for all threads to complete (WaitForMultipleObjects), add together the results and destory the threads</li> <li>Repeat</li> </ul> <p>What i would like to achieve is this:</p> <ul> <li>Split the buffer into N sub-buffers of the same size</li> <li>Assign each sub-buffer to a thread from the threadpool (which has exactly N threads)</li> <li>Once a thread finishes, let it sleep until another task is ready</li> <li>When all threads are done (and sleeping) add together the results they produced</li> <li>Repeat by waking up the threads and assign them new tasks</li> </ul> <p>As you can see, this is a bit of a special thread pool, since i need to wait for the threads to finish. Basically i want to get rid of the overhead of creating threads all the time, since the program goes through hundreds of thousands of iterations so it can create&destroy milions of threads over its lifetime. Good news is that i do not need any synchronization at all between threads, they all get their own data and storage place fot the results. However i must wait until all threads are finished and i have the final solution, because the next task depends on the results of the previous task.</p> <p>My main problem is with the management of threads:</p> <ul> <li>how do i make my threads "sleep" and wake them up once new task is ready?</li> <li>how do i wait for all the threads to finish?</li> </ul> <p>I will be grateful for any help. Also feel free to ask questions if i was not clear enough. Thanks!</p> |

123,773 | 0 | Is OOP & completely avoiding implementation inheritance possible? <p>I will choose Java as an example, most people know it, though every other OO language was working as well.</p> <p>Java, like many other languages, has interface inheritance and implementation inheritance. E.g. a Java class can inherit from another one and every method that has an implementation there (assuming the parent is not abstract) is inherited, too. That means the interface is inherited and the implementation for this method as well. I can overwrite it, but I don't have to. If I don't overwrite it, I have inherited the implementation.</p> <p>However, my class can also "inherit" (not in Java terms) just an interface, without implementation. Actually interfaces are really named that way in Java, they provide interface inheritance, but without inheriting any implementation, since all methods of an interface have no implementation.</p> <p>Now there was this <a href="http://www.javaworld.com/javaworld/jw-08-2003/jw-0801-toolbox.html" rel="nofollow noreferrer">article, saying it's better to inherit interfaces than implementations</a>, you may like to read it (at least the first half of the first page), it's pretty interesting. It avoids issues like the <a href="http://en.wikipedia.org/wiki/Fragile_base_class" rel="nofollow noreferrer">fragile base class problem</a>. So far this makes all a lot of sense and many other things said in the article make a lot of sense to me.</p> <p>What bugs me about this, is that implementation inheritance means <strong>code reuse</strong>, one of the most important properties of OO languages. Now if Java had no classes (like James Gosling, the godfather of Java has wished according to this article), it solves all problems of implementation inheritance, but how would you make code reuse possible then?</p> <p>E.g. if I have a class Car and Car has a method move(), which makes the Car move. Now I can sub-class Car for different type of cars, that are all cars, but are all specialized versions of Car. Some may move in a different way, these need to overwrite move() anyway, but most would simply keep the inherited move, as they move alike just like the abstract parent Car. Now assume for a second that there are only interfaces in Java, only interfaces may inherit from each other, a class may implement interfaces, but all classes are always final, so no class can inherit from any other class.</p> <p>How would you avoid that when you have an Interface Car and hundred Car classes, that you need to implement an identical move() method for each of them? What concepts for code reuse other than implementation inheritance exist in the the OO world?</p> <p>Some languages have Mixins. Are Mixins the answer to my question? I read about them, but I cannot really imagine how Mixins would work in a Java world and if they can really solve the problem here.</p> <p>Another idea was that there is a class that only implements the Car interface, let's call it AbstractCar, and implements the move() method. Now other cars implement the Car interface as well, internally they create an instance of AbstractCar and they implement their own move() method by calling move() on their internal abstract Car. But wouldn't this be wasting resources for nothing (a method calling just another method - okay, JIT could inline the code, but still) and using extra memory for keeping internal objects, you wouldn't even need with implementation inheritance? (after all every object needs more memory than just the sum of the encapsulated data) Also isn't it awkward for a programmer to write dummy methods like</p> <pre><code>public void move() { abstractCarObject.move(); } </code></pre> <p>?</p> <p>Anyone can imagine a better idea how to avoid implementation inheritance and still be able to re-use code in an easy fashion?</p> |

Blog readers should be able to select which languages they can/wish to read. For instance, if they chose English, then all entries which have English translation would appear in English, the remaining appearing in whatever language they were written, or not at all.</p></li> <li><p><strong>RSS customization</strong>: the blog will broach different subjects. I would like the users to be able to customize a RSS syndication which corresponds to their interests, so that the sigal to noise ration in their RSS readers remains bearable. This should probably work with a "Categoriy" or "Tag" system.</p></li> <li><p><strong>sub-blogs</strong>: I would like to have sub-blogs with their own url, which would present a subset of the blog entries. For instance my blog could deal with politics, sports, and myLife, and I could produce the following blog urls: blog.mydomain.tld (shows everything), opinions.mydomain.tld (shows only the politics related posts), sports.mydomain.tld (all entries dedicated to sports). I would also like to theme differently those sub-blogs (i.e. a ball picture for sports.mydomain.tld, etc).</p></li> <li><p><strong>modular privacy</strong>: my intended audience is heterogeneous (family, sets of friends, the internet), and I would like to be able to limit access to certain entries to different subsets of users. To me, the most obvious way to do this would be to define users with a login and password. I would then pool them into groups, and define for each entry if it is private, and if so which groups can read it. I do not necessarily want to share the same things between my neighbors and my school friends.</p></li> </ul> <p>That also brings the issue of RSS syndication: either each user would have its how RSS thread, or then RSS could be category specific and the private entries would appear without content. Perhaps other possibilities exist.</p> <p>These set of features are quite specific. I was thinking of using a blog software to implement them, but perhaps I'm thinking this wrong and I should use a CMS or even a framework?</p> <p>Another point is that this is done for "fun", and although I can program (python, etc), this is not my day job, so it should not require expert level skills or full time investment to implement. A solution which involves me developing a whole new blog application is not adapted to my constraints.</p> <p><strong>EDIT</strong></p> <ul> <li><strong>OpenID</strong>: I like the Stack Overflow login system (check this <a href="http://nsa20.casimages.com/img/2010/12/19/101219101041560868.png" rel="nofollow">screen capture of it</a>), because most readers already have an OpenID, and in any case do not need to create a specific one for my blog. The system I would use should be capable of using the OpenID method of authentication</li> </ul> |

22,672,108 | 1 | merging in pandas vs merging in R <p>I'm afraid I do not quite understand the merging capabilities of pandas, although I much prefer python over R for now.</p> <p>In R, I have always been able to merge dataframes very easily as follows:</p> <pre><code>> merge(test,e2s, all.x=T) Gene Mutation Chromosome Entrez 1 AGRN p.R451H chr1 375790 2 C1orf170 p.V663A/V683A chr1 84808 3 HES4 p.R44S chr1 57801 4 ISG15 p.S83N chr1 9636 5 PLEKHN1 p.S476P/S511P/S563P/S76P chr1 84069 </code></pre> <p>However, I have been unable to reconstruct this in pandas with merge(how="left,right,inner,outer")..

40,598,603 | 0 | <p>Well, you defintitely need a ETL tool then and preferably SSIS. First it will drastically improve your transfer rates while also providing robust error handling. Additionally you will have to use lookup transforms to ensure duplicates do not enter the sytsem. I would suggest go for Cache Connection Manager in order to perform the look-ups. </p> <p>In terms of design, if your source system (OurDB) is having a primary key say recId, then have a column say source_rec_id in your InterfaceDB table. Say your first run has transferred 100 rows. Now in your second run, you would then need to pick 100+1th record and move on to the next rows. This way you will have a tracking mechanism and one-to-one correlation between source system and destination system to understand how many records have got transferred, how many are left etc.</p> <p>For best understanding of SSIS go to <a href="https://channel9.msdn.com/Search?term=ssis#ch9Search&lang-en=en" rel="nofollow noreferrer">Channel 9 - msdn - SSIS</a>. Very helpful resource.</p> |

40,145,387 | 0 | this.style.background is returning wrong value <p>I am trying to create an RGB color guessing game.

19,210,874 | 0 | PHP/MySQL - Best way to work with dates in DD MMM YYYY format? <p>I need to display dates in the <strong>DD MMM YYYY</strong> format on the website I'm working on. My first thought was to store the dates in a DATE type in MySQL, then convert to the proper format using PHP. However, this is just returning <strong>01 Jan 1970</strong> - not the actual date of <strong>04 May 1891</strong>. </p> <p>I found a few other places where people have asked similar questions and the answer was always something like <code>SELECT date_format(dt, '%d/%m/%Y')</code> which was giving me <strong>04/05/1891</strong>. I want the month to be 3 characters (May, Jun, Jul, Aug, etc).</p> <p>I thought about storing the dates as a VARCHAR but that seems like it would be bad practice. It looks like I will have to store the date as a string and will not be able to use the PHP date() function because it cannot handle dates prior to 1970.</p> <p>I may want to do things like calculate ages which sounds painful when dealing with strings... I am wondering if anyone has a more elegant solution?</p> |
