"Emulate touch scroll in Java",
"I am searching for a way to create a touch application in Java (NOT for mobile devices) with a touch scroll support.\nIve been searching so far and I am investigating how this could be done - what ive found is the MT4J (http://www.mt4j.org/) but it seems that it would not support that (please correct me if i am wrong).\nSo my question is, how can i emulate a scroll event on a horizontal touch / swipe?\n\nThanks for help!\nKind Regards,\nAlex"

"How to bypass socket?",
"I have installed a streaming server \"Lighttpd\" (light-tpd) which runs on port 81.\n\nI have a C program that listens to http requests on port 80 using a server socket created by socket api.\n\nI want that as soon as I get a request on the port 80 from a client I forward that to the streaming server and the remaining conversation takes place b/w the Streaming Server and client & they bypass my C program completely.\n\nThe problem is client would be expecting msgs from socket at port 80 (i.e from the socket of my C program) since it had sent request to port 80 only rather than from the Streaming server which gives service on port 81.\ncan anyone help me out on this issue of bypassing the socket on port 80 for replying to the client.\n\nSolution I think: my program can be a middle man...It will forward the request to port 81 of streaming server and when it get replies from there it forwards them to the client...but bypassing would be efficient and I don't know how to do that. Please help me out.\n\nThanks in advance"

"Correlation between two moving-average smoothed variables",
"I have two time-series variables: mood and another external indicators. I want to compute the association between these variables. Let's say both have values for day 1 to N.\n\nI compute two types of associations:\n\nBy simply correlating these two vectors of N elements each.\nBy correlating the variables after they are smoothed with moving-averages. So, I compute the moving-averages of these variables with a window of M. This is computed by taking the average of first M elements, then moving forward by leaving the first element and including the M+1-th element, and so on. Finally, I compute the correlation between these two vectors of N-M+1 elements each.\nI don't see any correlation in the first case, however, in the seconds case I see a significantly moderate correlation. I am wondering if it is correct to use the correlations obtained by the second case. If not why?\n\nDoes the smoothening introduces temporal autocorrelation in both variables, which is the reason the I get significant correlation in the second case?\n\nI tried to search for this but found only the question below that has no accepted answer yet.\n\nhttps://math.stackexchange.com/questions/1239077/is-it-valid-to-get-a-correlation-between-moving-averages"

"Rule Engine in JavaScript",
"Is there any Rule engine in JavaScript? \n\nThe question is in this context:\n\n\nConsider a web application having a form that users fill up.\nAs a user fills up each field and proceeds to the next, business logic written in JavaScript controls the visibility(and other attributes) of form elements further down the page.\nThe same business logic is also applied at the server side after the form gets submitted, albeit, in Java to guard against any mishaps/manipulations at the browser side.\nNow, Wouldn't it be nice if we have a JSR 94/Drools/JRules like rule engine that would execute rules in both Java and in JavaScript? With such a rule engine, I can avoid hard coding my rules, and I also retain the flexibility of having client-side as well as server-side validation\n\n\n(PS: I've tried the AJAX route and seen that the application becomes a lot less responsive, making it hard to sell to users who've been accustomed to a hand-coded, pure-javascript version.)"

"Have a clickable page",
"What I want is to have a page with a Textblock in the middle. Also I want the page to be clickable (as in you should be able to click anywhere on the entire page and the function will be called).\n\nWhat I've tried is to have the TextBlock in a Viewbox and to set stretch to full, but that made the textblock text out of proportion. And if I set it to Uniform it only takes up however much space it needs. So either way it doesn't work.\n\nAlso the textblock needs to automatically resize itself when the page gets bigger / smaller (i.e. set Height and Width to \"Auto\"), I've tried a lot and nothing works, so any help is appreciated. Below is what I currently have.\n\n<Viewbox x:Name=\"MainViewbox\" Stretch=\"Uniform\" HorizontalAlignment=\"Center\" VerticalAlignment=\"Center\" Margin=\"1, 1, 1, 1\">\n <TextBlock x:Name=\"MainTextBlock\" HorizontalAlignment=\"Center\" VerticalAlignment=\"Center\" TextAlignment=\"Center\" Text=\"6\" Height=\"Auto\" Width=\"Auto\" Foreground=\"LightSkyBlue\"/>\n</Viewbox>\n\n\nThis Almost works but I can only click on the six, not on the whole screen.\n\nAnyway thanks in advance!"

"How to add Windows Credentials to Credentials Manager on Windows programmatically?",
"I have looked at this question's selected answer\nRetrieve Credentials from Windows Credentials Store using C#\n, which uses the CredentialManagement NuGet package to get and set credentials on Windows.\n\n\n Credential Management package is a wrapper for the Windows Credential Management API that supports both the old and the new style of UI\n\n\nI was able to set new credentials that way, however they were set as Generic Credentials. \n\npublic static bool SetCredentials(\n string target, string username, string password, PersistanceType persistenceType)\n {\n return new Credential\n {\n Target = target,\n Username = username,\n Password = password,\n PersistanceType = persistenceType\n }.Save();\n }\n\n\nAccording to this, there are at least 4 different types of credentials that the Windows Credentials Manager can use:\n\n\nWindows Credentials\nCertificate-Based Credentials\nGeneric Credentials\nWeb Credentials\n\n\nThe credentials I need to set are intended to allow access to a specific local web server, and when I have added them manually as Windows Credentials they work, when they get added as Generic Credentials by the application, or myself, they don't work.\n\n\n\nI couldn't find enough information about this here, so what I need to know is how to add Windows Credentials to the Windows Credentials Manager by using this package, or in any other way that can be done programmatically.\n\nUPDATE: I managed to solve my issue by doing it the way it's shown on this question: C# Using CredWrite to Access C$. However, since I didn't want to answer the same thing here as well, I will leave the question open in case someone knows how to do it differently, or else I will vote to close it.\n\nUPDATE 2: Although by the time the previous update was posted the solution that was found then was working, it's not working now. So I'm still looking for a way to completely solve this problem. I'm sure the previous link can still be useful for someone else though."

"Is it possible to pass command-line arguments to @ARGV when using the -n or -p options?",
"I think the title of my question basically covers it. Here's a contrived example which tries to filter for input lines that exactly equal a parameterized string, basically a Perlish fgrep -x:\n\nperl -ne 'chomp; print if $_ eq $ARGV[0];' bb <<<$'aa\\nbb\\ncc';\n## Can't open bb: No such file or directory.\n\n\nThe problem of course is that the -n option creates an implicit while (<>) { ... } loop around the code, and the diamond operator gobbles up all command-line arguments for file names. So, although technically the bb argument did get to @ARGV, the whole program fails because the argument was also picked up by the diamond operator. The end result is, it is impossible to pass command-line arguments to the Perl program when using -n.\n\nI suppose what I really want is an option that would create an implicit while (<STDIN>) { ... } loop around the code, so command-line arguments wouldn't be taken for file names, but such a thing does not exist.\n\nI can think of three possible workarounds:\n\n1: BEGIN { ... } block to copy and clear @ARGV.\n\nperl -ne 'BEGIN { our @x = shift(@ARGV); } chomp; print if $_ eq $x[0];' bb <<<$'aa\\nbb\\ncc';\n## bb\n\n\n2: Manually code the while-loop in the one-liner.\n\nperl -e 'while (<STDIN>) { chomp; print if $_ eq $ARGV[0]; }' bb <<<$'aa\\nbb\\ncc';\n## bb\n\n\n3: Find another way to pass the arguments, such as environment variables.\n\nPAT=bb perl -ne 'chomp; print if $_ eq $ENV{PAT};' <<<$'aa\\nbb\\ncc';\n## bb\n\n\nThe BEGIN { ... } block solution is undesirable since it constitutes a bit of a jarring context switch in the one-liner, is somewhat verbose, and requires messing with the special variable @ARGV.\n\nI consider the manual while-loop solution to be more of a non-solution, since it forsakes the -n option entirely, and the point is I want to be able to use the -n option with command-line arguments.\n\nThe same can be said for the environment variable solution; the point is I want to be able to use command-line arguments with the -n option.\n\nIs there a better way?"

I don't know why it works with the devtool opens and the debugger.\n\nSomething interesting that happens as well is that when I switch to a different view such as dayGridMonth and then switch back to resourceTimeline, the resourceTimeiline adjusts its width properly, and fits perfectly.\n\n\n\nAny ideas on how to I could fix this? \n\nThank you in advance!"

"mySQL Efficiency Issue - How to find the right balance of normalization...?",
"I'm fairly new to working with relational databases, but have read a few books and know the basics of good design.\n\nI'm facing a design decision, and I'm not sure how to continue. Here's a very over simplified version of what I'm building: People can rate photos 1-5, and I need to display the average votes on the picture while keeping track of the individual votes. For example, 12 people voted 1, 7 people voted 2, etc. etc.\n\nThe normalization freak of me initially designed the table structure like this:\n\nTable pictures\nid* | picture | userID | \n\nTable ratings\nid* | pictureID | userID | rating\n\n\nWith all the foreign key constraints and everything set as they shoudl be. Every time someone rates a picture, I just insert a new record into ratings and be done with it.\n\nTo find the average rating of a picture, I'd just run something like this:\n\nSELECT AVG(rating) FROM ratings WHERE pictureID = '5' GROUP by pictureID \n\n\nHaving it setup this way lets me run my fancy statistics to. I can easily find who rated a certain picture a 3, and what not. \n\nNow I'm thinking if there's a crapload of ratings (which is very possible in what I'm really designing), finding the average will became very expensive and painful.\n\nUsing a non-normalized version would seem to be more efficient. e.g.:\n\nTable picture\nid | picture | userID | ratingOne | ratingTwo | ratingThree | ratingFour | ratingFive\n\n\nTo calculate the average, I'd just have to select a single row. It seems so much more efficient, but so much more uglier.\n\nCan someone point me in the right direction of what to do? My initial research shows that I have to \"find the right balance\", but how do I go about finding that balance? Any articles or additional reading information would be appreciated as well.\n\nThanks."

"User inputs a date.\n\nBased on this date, I have to get the first day of each month of the year in this date.\n\nExample:\n\nUser input: 2/1/2014\n\nFrom that, I need an expression that will get me -\n\n1/1/2014\n3/1/2014\n4/1/2014\n\n\nand so on.\n\nI need the expression for each of the dates (not all together).\n\nBasically if someone can help me figure out how to get one of the dates, I can do the rest.\n\nEDIT - I got it guys. Sorry I wasn't clear enough.\n\n=CDate(\"1/1/\" + Year(Now).ToString)\n=CDate(\"2/1/\" + Year(Now).ToString)\n=CDate(\"3/1/\" + Year(Now).ToString)\n\n\nand so on."

"Finding whether an activity is available on a certain date given a cycle of on/off periods",
"This problem is killing me and I can't help but think there is an easy way to do this.\nI have some activities that can be performed for 'x' number of days, then held for 'x' number of days then performed again and again. The activities should start on a certain day and the cycles should repeat.\nSo for example, John must wash the car starting on 2020/4/15 and he must wash it for 3 days, then he is off for 7 days, then the cycle repeats on the following day.\nThe problem is that given a certain day (i.e. today), how can I calculate whether or not he is to wash the car? I have tried calculating the number of cycles since the start date, then multiplying that number times the cycle period (in this case the cycle would be 10 days) and trying to arrive at a new start date but that isnt working. Also tried subtracting the cycle total from todays date but something about this is really messing me up.\nAnyone have an idea that could point me in the right direction?"

"How can template functions know size when size info is not explicitly stated?",
"template<size_t ROWS, size_t COLS>\nvoid f(const array<array<int, COLS>, ROWS>& arr)\n{\n for(size_t r=0; r<ROWS; r++)\n for(size_t c=0; c<COLS; c++)\n //stuff\n}\n\narray<array<int, 2>, 3> arr {{{1,2},{3,4},{5,6}}};\n\nf(arr);\n\n\nThis works but how? How does the template function figure out the row and col size? I'm not passing in size info during function call. I can see how template functions can figure out the type of the object being passed in, but in such a case I don't see how my ROWS and COLS are given values.\n\nThis question seeks understanding of this particular case with templates. The question isn't asking about vector or what other data structures exist."

"Why does malloc_trim() only work with the main arena?",
"glibc's malloc implementation supports 'malloc_trim()' call that lets an application program release unused(ie freed memory chunks) back to the system(implementation detail: the data segment of the program is reduced by calling sbrk() with a negative argument). However, this function only works with the main arena. In multithreaded programs, there are multiple arenas that hold freed chunks. Why does this call not release memory from the other arenas as well?"

"Zend Framework create a sql function",
"I would like to create a sql query in Zend Framework in the Abstract.php or in model? but I have a hard time figure out how to do it. I am new in zend framework.\n\nThe query that I want to create looks like that:\n\ndelete from users where id not in(select * from(select min(n.id)from users n group by n.email)x);\n\n\nBut in zend:\n\n$results = $db->query('delete\n from users\n where id not in(\n select * from(\n min(n.id)\n from users n\n group by n.email\n )x)');\n\n\nLook like the $db got a undefined variable, what kind of database function should the db call? My database is being call in the application.ini"

"Why are the urls and headers of two requests seemingly the same but have different status codes (404 and 200, respectively)?",
"I am trying to crawl pages like this http://cmispub.cicpa.org.cn/cicpa2_web/07/0000010F849E5F5C9F672D8232D275F4.shtml. Each of these pages contains certain information about an individual person.\n\nThere are two ways to get to these pages. \n\nOne is to coin their urls, which is what I used in my scrapy code. I had my scrapy post request bodies like ascGuid=&isStock=00&method=indexQuery&offName=&pageNum=&pageSize=&perCode=110001670258&perName=&queryType=2to http://cmispub.cicpa.org.cn/cicpa2_web/public/query0/2/00.shtml.\n\nThese posts would return response where I can use xpath and regex to find strings like'0000010F849E5F5C9F672D8232D275F4' to coin the urls I really wanted:\n\n next_url_part1 = 'http://cmispub.cicpa.org.cn/cicpa2_web/07/'\n next_url_part2 = some xptah and regex...\n next_url_part3 = '.shtml'\n next_url_list.append([''.join([next_url_part1, i, next_url_part3]))\n\n\nFinally, scrapy sent GET requests to these coined links and downloaded and crawled information I wanted.\nSince the pages I wanted are information about different individuals, I can change the perCode= part in those POST request bodies to coin corresponding urls of different persons.\n\nBut this way sometimes doesn't work out. I have sent GET requests to about 100,000 urls I coined and I got 5 404 responses. To figure out what's going on and get information I want, I firstly pasted these failed urls in a browser and not to my suprise I still got 404. So I tried the other way on these 404 urls. \n\nThe other way is to manually access these pages in a browser like a real person. Since the pages I wanted are information about different individuals, I can write their personal codes on the down-left blank on this page http://cmispub.cicpa.org.cn/cicpa2_web/public/query0/2/00.shtml( only works properly under IE), and click the orange search button down-right(which I think is exactly like scrapy sending POST requests). And then a table will be on screen, by clicking the right-most blue words(which are the person's name), I can finally access these pages.\n\nWhat confuses me is that after I practiced the 2nd way to those failed urls and got what I want, these previously 404 urls will return 200 when I retry them with the 1st way(To avoid influences of cookies I retry them with both scrapy shell and browser's inPrivate mode). I then compared the GET request headers of 200 and 404 responses, and they looks the same. I don't understand what's happening here. Could you please help me?\n\nHere is the rest failed urls that I haven't tried the 2nd way so they still returns 404(if you get 200, maybe some other people have tried the url the 2nd way):\n\nhttp://cmispub.cicpa.org.cn/cicpa2_web/07/7694866B620EB530144034FC5FE04783.shtml\nand the personal code of this person is\n110001670258\n\nhttp://cmispub.cicpa.org.cn/cicpa2_web/07/C003D8B431A5D6D353D8E7E231843868.shtml\nand the personal code of this person is\n110101301633\n\nhttp://cmispub.cicpa.org.cn/cicpa2_web/07/B8960E3C85AFCF79BF0823A9D8BCABCC.shtml\nand the personal code of this person is 110101480523\n\nhttp://cmispub.cicpa.org.cn/cicpa2_web/07/8B51A9A73684ADF200A38A5D492A1FEA.shtml\nand the personal code of this person is 110101500315"
