"Situations where CakePHP 2 might not populate `created` or `modified` fields on a table",

"Elastic Beanstalk optionsettings file keep getting overwritten with default parameters",
"While trying to setup an elastic beanstalk worker application using the command line tools (eb tools), my configuration file (optionsettings.MyApp-env) gets overwritten when I start/update/stop the environment.\n\nThese are the steps to reproduce:\n\n\nUsing the CLI tools' command eb init I've created a new application in Elastic Beanstalk. \nThe config file in the .elasticbeanstalk folder had the following line:\nOptionSettingFile=/Users/doron/projects/workers/my-worker/.elasticbeanstalk/optionsettings.MyWorkerName-dev\nAfter running eb start for the first time, that file was created with some values. \nI went ahead and changed its contents according to http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/command-options.html so it'll be configured as I want (environment parameters, autoscaling servers amount, etc...).\nTo apply the changes I've tried the following:\n\n\nUpdate the existing environment with eb update.\nTerminate the existing environment with eb stop and build it from scratch with eb start.\n \n\n\nIn both cases the optionsettings file get changed after running the command (update or start). \n\nThe new content of the file looks more like the vanilla version I got after calling the first eb start with all sorts of configuration parameters that I added - removed completely.\n\n\nIs there another way of configuring the environment (not the software on the machine, but the configuration that exists in the console - instance type, regions, autoscaling, rotating updates, etc...) ?"

"Does Python create a new list when a sliced list is a parameter in a recursive function?",
"For the purposes of understanding recursion and its performance in Python I wrote a recursive function that returns the maximum in the list:\ndef max_list(A):\n print(id(A)) # debugging purposes\n if len(A) > 1:\n max_list_tail = max_list(A[:-1])\n else:\n max_list_tail = A[0]\n if A[-1] > max_list_tail:\n return A[-1]\n else:\n return max_list_tail\n\nThe idea behind this function is that if the last element of the current list is greater than the maximum among the 'tail' of the list, which is, all the elements, except for the last one, that the last one is the maximum, otherwise the maximum of the tail is the maximum.\nAs you can see, I pass a sliced list A[:-1] as a parameter.\nQuestions:\n\nAm I right saying the following: Each time I pass A[:-1] a new list is created, which is a copy of my old list except for the last element? For debugging purposes I print the id of each sliced list and the ids are different which prompts me to think I'm right but I want confirmation from the expert community.\n\nIf 1. is yes, that's true, what is the time complexity of my function? Can I say that it is O(n^2) because it takes O(n) to find the maximum in the initial list and O(n) to create a copy of the current list each time I recursively call the function?"

"Doctrine ORM and factories with abstract classes strategy",
"So I've stumbled upon this hurdle where I have to create an abstract class and a factory to create objects of more specific classes that extend the abstract class and implement more specific object methods.\n\nSimply said, I got a SocialMediaAbstract class. Extending classes are Facebook, Instagram, and they implement a SocialMediaInterface. Facebook, Instagram etc are all saved in the db, with an id, a name and several more properties that are all used among the extending classes, hence an abstract class.\n\nBecause I want to be able to query several things from the SocialMedia Objects, and every social media platform have their own APIs for it, I made the interface and created the different classes so they can all have their own implementations of those methods.\n\nNow, the problem is of course with my abstract class and Doctrine. Doctrine says this on their website regarding inheritance:\n\n\n A mapped superclass cannot be an entity, it is not query-able [...]\n\n\nNow if I had a SocialMediaFactory and threw in an ID, I would like to get the respective Object of, for example, class Facebook or Instagram back. I don't want to know exactly which SocialMedia it is when I collect them. Now that is a problem with doctrine, at least that's what I think it is.\n\nAm I overlooking something, is the factory pattern still possible? Or should I really just remove the abstract class, and create a factory that searches in every table of a SocialMediaInterface implementing class, which seems highly inefficient and unmaintable when an application gets bigger.\n\nAny insight or pointers would be appreciated, since I'm sure this problem must've come up more often. I tried googling and searching on Stackoverflow itself, but I couldn't get any relevant questions or answers.\n\nThank you very much in advance.\n\nEDIT:\nI came across this interesting possibility: Class Table Inheritance. This would mean adding:\n\n * @ORM\\InheritanceType(\"JOINED\")\n * @ORM\\DiscriminatorColumn(name=\"discr\", type=\"string\")\n * @ORM\\DiscriminatorMap({\"facebook\" = \"Facebook\", \"instagram\" = \"Instagram\"})\n\n\nto my code. I had high hopes, but sadly enough the validator gave me this error:\n\n\n [Doctrine\\ORM\\Mapping\\MappingException]\n It is not supported to define inheritance information on a mapped superclas\n s 'Portal\\SocialMedia\\Entity\\SocialMediaAbstract'.\n\n\nA shame mapper superclasses are not supported.\n\nEDIT 2/CONCLUSION:\nI've decided to go with Class Table Inheritance (just like the answer below suggested). Removing the abstract from the class made it possible to still use my factory.\n\nI am using a concrete class as an abstract class now however, which feels wrong. I've documented in docblock that no objects should be instantiated from this class.\n\nOne little sidenote: Doctrine's Entity Manager more or less already provides the Factory:\n\n$socialMedia = $entityManager->find('Portal\\SocialMedia\\Entity\\SocialMedia', 2);\n\n\nThis returns an Instagram object. I still suggest you build your own factory above it for maintainability later as the SocialMedia entity might change later on."

"Mark the Mark Scheme",
"I have successfully completed an AQA Computing exam (June 2011) in Delphi. Out of curiosity, I read the mark scheme for it. One thing I can't get over is that the C language mark scheme seems to be wrong on many aspects. Luckily (ha!) I did it in Delphi.\n\nFor example, this small snippet:\n\nchar* Names[5];\n...\nvoid main(void)\n{\n Names[1] = \"Ben\";\n Names[2] = \"Thor\";\n Names[3] = \"Zoe\";\n Names[4] = \"Kate\";\n ...\n}\n\n\nFor one, it's not possible to assign strings to an array. A function like strcpy must be used. Also, why do the arrays start at 1, even though 5 entries have been allocated? Most programming languages, including C, start at 0.\n\nThere are other problems, for example they use printf(\"%s\", \"message\"); to print strings; puts would be fine. And if you can be certain no unescaped percent signs would show up in the message, so would printf alone, with no arguments. \n\nAm I right in my criticism of this?\n\nNote: For those unfamiliar with mark schemes, they are what is used to mark the exams. I am questioning whether it is correct."

I've read there is a nice package RGoogleMaps, which allows that, but the problem is that I am using ggplot2. \nAny idea how can I add an arrow and markers to my map?\nThanks in advance!\n\nhere is my code:\n\nrequire(move)\nrequire(ggmap)\nrequire(mapproj)\ngps <- move(x=temp$GPS_x, y=temp$GPS_y,time=as.POSIXct(temp$GPS_timeDate, format=\"%d/%m/%Y %H:%M:%S\", tz=\"UTC\"), proj=CRS(\"+proj=longlat +ellps=WGS84\"), animal='unknown', sensor='NoName')\ngps_df <- as(gps, \"data.frame\")\nm <- get_map(bbox(extent(gps)*1.1), source=\"osm\", zoom=14)\nggmap(m)+geom_path(data=gps_df[1:nrow(soc_long),], aes(x=temp$GPS_x[1:nrow(soc_long)], y=temp$GPS_y[1:nrow(soc_long)],colour=soc_long$dsoc),size=1.5,lineend=\"round\")+scale_color_gradient(low='green',high='red')\n\n\nThe output is the following: \n\n\nThis is the part of temp data set: \n\nGPS_timeDate GPS_x GPS_y\n13/11/13 14:54:15 10.17936802 54.33073984\n13/11/13 14:54:16 10.17936768 54.33073967\n13/11/13 14:54:17 10.17936735 54.33073951\n13/11/13 14:54:18 10.17936702 54.33073934\n13/11/13 14:54:19 10.17936668 54.33073917\n13/11/13 14:54:20 10.17936635 54.33073901\n13/11/13 14:54:21 10.17936601 54.33073884\n13/11/13 14:54:22 10.17936568 54.33073867\n13/11/13 14:54:23 10.17936535 54.33073851\n13/11/13 14:54:24 10.17936501 54.33073834\n13/11/13 14:54:25 10.17936547 54.33073849\n13/11/13 14:54:26 10.17936597 54.33073866\n13/11/13 14:54:27 10.17936646 54.33073882\n13/11/13 14:54:28 10.17936696 54.33073899\n13/11/13 14:54:29 10.17936745 54.33073915\n13/11/13 14:54:30 10.17936794 54.33073931\n13/11/13 14:54:31 10.17936844 54.33073948\n13/11/13 14:54:32 10.17936893 54.33073964\n13/11/13 14:54:33 10.17936943 54.33073981\n13/11/13 14:54:34 10.17936992 54.33073997\n13/11/13 14:54:35 10.17936943 54.33074\n13/11/13 14:54:36 10.17936875 54.33074\n13/11/13 14:54:37 10.17936807 54.33074\n13/11/13 14:54:38 10.17936739 54.33074\n13/11/13 14:54:39 10.17936671 54.33074\n13/11/13 14:54:40 10.17936603 54.33074\n13/11/13 14:54:41 10.17936535 54.33074\n13/11/13 14:54:42 10.17936467 54.33074\n13/11/13 14:54:43 10.17936399 54.33074\n\n\nsoc_long data set's values are used for color gradient:\n\n dsoc\n1 0.348334562\n2 0.348334562\n3 0.348334562\n4 0.348334562\n5 0.348334562\n6 0.348334562\n7 0.348334562\n8 0.348334562\n9 0.348334562\n10 0.348334562\n11 0.367477325\n12 0.367477325\n13 0.367477325\n14 0.367477325\n15 0.367477325\n16 0.367477325\n17 0.367477325\n18 0.367477325\n19 0.367477325\n20 0.367477325\n21 0.248041791\n22 0.248041791\n23 0.248041791\n24 0.248041791\n25 0.248041791\n26 0.248041791\n27 0.248041791\n28 0.248041791\n29 0.248041791\n30 0.248041791\n\n\nAnd finally, the following pints are the point that I want to add as markers to the path:\n\nlat lon\n54.31545667 10.168515\n54.30135833 10.14450333\n54.30305167 10.137645\n54.3072 10.13840667\n54.31827833 10.13377\n54.32098833 10.12690667\n54.32025833 10.12314\n54.31826833 10.12340333\n54.31540667 10.12799167\n54.31492167 10.13006833"

"Language choices for writing very fast abstractions interfacing with Python?",
"I have a system currently written in Python that can be separated into backend and frontend layers. Python is too slow, so I want to rewrite the backend in a fast compiled language while keeping the frontend in Python, in a way that lets the backend functionality be called from Python. What are the best choices to do so?\n\nI've considered cython but it's very limited and cumbersome to write, and not that much faster. From what I remember of Boost Python for C++, it's very annoying to maintain the bridge between languages.

"React.js dialog component disappears yet remains in DOM",
"I'm using a Dialog component from Material-UI which, for the most part, is working correctly. However, if I click away from the Dialog, the Dialog will disappear (as expected) but sometimes, it remains in the DOM with its opacity set to 0, and I can't click anything else since the Dialog is in the way. This is a small sample of my code:\n\n const [openDialog, setOpenDialog] = React.useState(false);\n\n React.useEffect(() => {\n // Get data for ReactTable\n }, []);\n\n return(\n <div>\n // Other components\n <Button color=\"white\" onClick={() => setOpenDialog(true)}>\n Open Dialog\n </Button>\n // Other components\n <Dialog open={openDialog} maxWidth=\"md\" onClose={() => setOpenDialog(false)}>\n // ReactTable and close button\n </Dialog>\n </div>\n )\n\n\nThis bug doesn't always occur which makes it tricky to debug. I've only been using React for about a month, but I'm wondering if it's a state problem, or maybe some sort of race condition. Any suggestions?\n\nEdit: This also occurs when a DropzoneDialog appears, to upload a file."

"Tomcat Persistence Manager Kills Session Logins",
"For my web app, I use tomcat declarative security to tie login credentials to the company Active Directory. On two of our servers, logins were timing out after one minute of inactivity. On the other two servers, there is a thirty minute timeout (which is what I want).\n\nYeseterday, I found the cause of the problem. The two servers with one minute timeouts have a tomcat Persistence Manager enabled to write session information to disk. Our IT guy is out this week, so I don't know the exact details of what he was trying to accomplish with this, but he had set PersistenceManager up like this in context.xml:\n\n<Manager sessionIdLength=\"64\" className=\"org.apache.catalina.session.PersistentManager\"\n maxIdleBackup=\"10\" maxIdleSwap=\"30\">\n <Store className=\"org.apache.catalina.session.JDBCStore\" dataSourceName=\"jdbc/Auth\"\n sessionTable=\"sessions\" sessionAppCol=\"app_name\" sessionDataCol=\"session_data\" sessionIdCol=\"session_id\"\n sessionLastAccessedCol=\"last_access\" sessionMaxInactiveCol=\"max_inactive\" sessionValidCol=\"valid_session\" />\n</Manager>\n\n\nI did some research and discovered that the Idle numbers are in seconds. Thinking that might be the culprit I changed the Manager portion to:\n\n<Manager sessionIdLength=\"16\" className=\"org.apache.catalina.session.PersistentManager\"\n maxIdleBackup=\"600\" maxIdleSwap=\"3600\" minIdleSwap=\"1800\">\n\n\nThis fixed my problem. So it appears that forcing the Persistence Manager to write sessions out to disk after thirty seconds of inactivity was killing my session logins. I tracked the JSESSIONID cookie and found that the cookie remained the same even after the user is forced back to the login screen. It only changes when you re-login. This is what you would expect, because persisting the session to disk couldn't possibly change the session id. However, it does cause my declarative security model to force the user to log in again.\n\nI did find in the manual that the maxIdleSwap variable not only controls persisting sessions to disk, but also causes the \"passivating of the session out of server memory\". This sounds a bit suspicious to me.\n\nDoes anyone have any experience with this issue? Why does the Persistence Manager kill my web app logins when it persists sessions to disk? Is there any way around this without changing the swap control variables like I did?"

NOTE: this is not an error displayed from PHP, it seems more like an error comming from the browser.\n\nI have checked my code for syntaxes many times, i have also tried out and other gd functions, like imagegif, imagettftext etc etc but didn't have any effect. Here's my code:\n\n//$image = @imagecreate(200, 20)or die(\"Cannot Initialize new GD image stream\");\n$image = imagecreate(200, 20);\n$background = imagecolorallocate($image,0,0,0);\n$foreground = imagecolorallocate($image,255,255,255);\nimagestring($image,5,5,1,\"This is a Test\",$foreground);\nheader(\"Content-type: image/jpeg\");\nimagejpeg($image);\nimagedestroy($image);\n\n\nGD library is enabled i've already checked that in phpinfo(), and I have also tried to preview it and on Chrome and looks the same. Any ideas what i might doing wrong or why happens this? and how can i fix this error??"

"Applying dictionary to dictionary",
"Recently I've found a technique of applying dict to dict. It is something like this:\n(3 4 5!6 7 8)[(`a`b)!(2 3)] ~ (`a`b!0N 6)\n\nor even this, which looks more natural for reading from left to right:\n(@[;(`a`b)!(2 3)](3 4 5!6 7 8)) ~ (`a`b!0N 6)\n\nCan I use this behavior (are there any caveats)? Is it described somewhere in the official docs?\n\nIt seems like absolutely mind-blowing technique: we definitely apply function(list/dictionary/table) to it's argument, not just pass argument to a function."

"VBA PPT copy/paste chart inconsistent",

I'm creating multiple slides already with no issues and tackled most problems already.\n\nOne of the final things for me to do is copy a chart from excel and pasting it in my ppt. This has worked before, but suddenly it just breaks, it doesnt want to paste the chart anymore.\n\nIn my main module I call sub ROI with some required data to continue\n\n\nCall ROI(PPPRes, Slidestart, language, i)\n\n\n\nThis is in a seperate Module to keep things clean in the main module\n\n\nSub ROI(PPPRes, Slidenumber, language, proposal)\nSet pp = CreateObject(\"PowerPoint.Application\")\nDim oPPTShape As PowerPoint.Shape\nDim PPSlide As PowerPoint.Slide\nDim ColumnWidthArray As Variant\nDim i As Integer\n\n'Create a slide on Slidenumber location\nSet PPSlide = PPPRes.Slides.Add(Slidenumber, ppLayoutTitleOnly)\nPPSlide.Select\nPPSlide.Shapes(\"Title 1\").TextFrame.TextRange.Text = Range(\"Titlename in chosen language\")\nPPSlide.Shapes.AddTable(3, 3).Select\nSet oPPTShape = PPSlide.Shapes(\"Table 4\")\n\n'Filling in data in the table from an excel table. Basic stuff working with a few loops to make this happen\n\n\n 'Changing the width of the created table, column by column\n ColumnWidthArray = Array(37, 210, 180)\n Set oPPTShape = PPSlide.Shapes(\"Table 4\")\n On Error Resume Next\n With oPPTShape\n For i = 1 To 3\n .table.columns(i).width = ColumnWidthArray(i - 1)\n Next i\n .Top = 180\n .Left = 520\n .height = 200\n End With\n\n 'Add a rectangle on the slide\n PPSlide.Shapes.AddShape Type:=msoShapeRectangle, Left:=404, Top:=400, width:=153, height:=43\n\n 'Copy a picture from excel and paste it in the active slide \n Sheets(\"Shapes\").Shapes(\"ROI_img\").Copy\n PPSlide.Shapes.Paste.Select\n pp.ActiveWindow.Selection.ShapeRange.Left = 800\n pp.ActiveWindow.Selection.ShapeRange.Top = 20\n\n'Copy chart from excel (with index number that is linked to \"proposal\") and then paste onto slide\nSheets(\"Proposals\").Shapes(\"ChartInvProp\" & proposal).Copy\nPPSlide.Shapes.Paste.Select\nSet oPPTShape = PPSlide.Shapes(\"ChartInvProp\" & proposal)\nWith PPSlide.Shapes(\"ChartInvProp\" & proposal)\n .Left = 20\n .Top = 120\n .width = 480\n .height = 320\nEnd With\nend sub\n\n\n\nSo everything in the code is executed, but most of the time the chart from excel is NOT being pasted onto the slide.\nHowever, if I checked what is in the clipboard by breaking the code just after copying the chart from excel. And I then manually paste whatever is in the clipboard into a Word document I will see the chart. --> The action of copying the chart is being executed, but not the pasting part\nIf I now continue after the break, the chart will be pasted on the powerpoint somehow. But if I do NOT break the code, and let it run its course, the chart will not be pasted.\n\nSomehow it seems to need more time after copy before it can actually paste the chart. I dont really understand what is happening here.\nSometimes it only pastes Chart 1 in the slide, and when it loops for the second/third/etc... chart it doesnt want to paste it anymore.\n\nIt really is very random, and I only see a little bit of structure in it not executing..."

When I give:\n\ndat_forward<-rbind(dat,NAs)\nis.factor(dat_forward$x)\n\n\nthis works fine. However the backward direction using rbind fails:\n\ndat_backward<-rbind(NAs,dat)\nis.factor(dat_backward$x)\nis.character(dat_backward$x)\n\n\nNow x is coerced to character level. I am confused - can't it stay factor type even if I use the other order of binding? What would be a straight forward change to my code to reach my goal?"

"packaging Java library with dependencies in OSGi/Eclipse jars",
"I am finishing a Java library that I want to make available to third parties. \nIn addition to its core functionality, I am providing some classes that ease the usage of my library when used as part of an Eclipse plugin.\nThen, I have some dependencies in my library to certain OSGi/Eclipse classes (e.g., org.osgi.framework.Bundle, org.eclipse.core.runtime.FileLocator, org.eclipse.jdt.core.dom.CompilationUnit, among others).\n\nSo my questions is: What is the correct/convenient way to package this library for third parties usage?. Should I include all the Eclipse jars that contain the required dependencies ?. Intuitively, I think this is not a good solution given that the user obviously could have a different Eclipse version than the one I have, and this could lead to class loading conflicts. The solution of just not providing the Eclipse jars - and asking the user to find the ones he/she likes - does not really convince me neither.\n\nI do not have lots of experience with Maven, but as far as I understand I can create a POM file that the user can use for downloading the last version of my project and its dependencies. But again: in that case I also have to decide if I should include or not the Eclipse jars in the download, considering the reasons I wrote above.\n\nThanks for sharing your experience on this regard."

"Difference between parallel and sequential Convolutions in Convolutional Neural Network",

I already found some implemented models and found especially two implementations: \n\n[I'm not allowed to post more than 2 Links, I will try to provide the sources in the comments]\n\nHowever they seem to differ fundamentally in their architecture. The first model uses the convolutions parallel with the input data whereas the second model uses the convolutions in a sequential way. I visualized the two models with tensorboard:\n\nFirst the parallel convolutions. After the convolutions the results are concated and with one fully connected layer the output is created.\n\nparallel use of convolutions\n\nThe sequential convolutions seem to be more straight forward, we use the result form the previous layer as the input for the next layer. \n\nsequential use of convolutions\n\nSo my question is, since both are used to classify text, where lies the difference between these two implementations and which one is more suitable for classifying text?"

"How to walk the line between location accuracy and power efficiency?",
"I am working on an app that requires to work in foreground and background and send location data. I haven't written code yet and just familiarized myself with how CoreLocation works to determine which approach to follow. From the reading I did so far, I gather that:\n\n\nWith startMonitoringSignificantLocationChanges \n\n\nthe GPS is never activated \nit only calls didUpdateLocations (or didUpdateToLocation for ios<6) when a change of radio tower is detected \nthe desiredAccuracy and distanceFilter properties are both ignored\n\nWith startUpdatingLocation\n\n\nthe battery drain is higher\ndidUpdateLocations is called whenever some hardware from the phone has some data to provide. And because there are multiple hardware components that can be used for location (GPS, radio, wifi), there is no guarantee when or how often didUpdateLocations is called, or whether a new reading will be more accurate than the previous one even\nthe first number(s) are usually bad because they do not rely on the GPS\nthere is no sure way of knowing whether we have the best location we will ever get: it is just a matter of picking among all locations received the one with the best accuracy in the given time window available \n\n\n\nI don't see however much discussion or documentation about any intermediate route. What if I want to be power-conscious but get reasonably accurate data when a user has moved significantly? It seems that a possible compromise approach is to:\n\n\nturn on startMonitoringSignificantLocationChanges\nswitch to using startUpdatingLocation when didUpdateLocations is called\nwait for a short while to give a chance to the GPS to get some good readings and select the one with best accuracy \nswitch back to using startMonitoringSignificantLocationChanges and so on...\n\n\nAs far as I know, this approach will work the same in foreground and background and will provide some compromise between the two standard approaches supported by Apple.\n\nQuestions:\n- Is my understanding correct and my \"compromise\" approach sound?\n- Has anyone used that approach successfully?\n- What are the caveats to look for with that approach?\n- Is there a better compromise approach out there?\n\nPS: I imagine that I could later refine the approach to take into account the estimated travel speed so that I don't constantly use the GPS when the person is traveling."
