"Why do we sometimes prefer having data structures over objects?",
"As Robert Martin's Clean Code said:\n\n\n Objects hide\n their data behind abstractions and expose functions that operate on that data. Data structure\n expose their data and have no meaningful functions.\n\n\nBut he also mentioned that:\n\n\n Procedural code (code using data structures) makes it easy to add new functions without\n changing the existing data structures. OO code, on the other hand, makes it easy to add\n new classes without changing existing functions.\n\n\nand:\n\n\n ...\n Such hybrids make it hard to add new functions but also make it hard to add new data\n structures. They are the worst of both worlds. Avoid creating them.\n\n\nHybrid above means the hybrid between data structure and objects. \n\nBut it seems there is a conflict for data structure: the pros of using data structure is for adding functions easier, but for data structure we'd better never add functions in it. Then what's the point of having data structure? E.g. DTO(data transfer object) are one of the examples of using data structure instead of using objects. And it's always a good practice to not add a lot of logic out of getters in it. -- But why?"

"How to associate a subclass Object with a superclass object?",
"I have a question on how I can create a new object and associate it with another already initialized object from its parent class in java.\nTo be clearer, I have a superclass Profile, then a subclass Contract which extends Profile and then two other subclasses HomePhone and MobilePhone that both extend Contract.\nTwo of the options of my menu are:\n\nNew profile.\nNew contract(HomePhone or MobilePhone contract).\n\nSuppose that the user has already created a profile without a contract and has entered some personal information. I initialize a Profile object and then i store it to an ArrayList.\nProfile p = new Profile();\n/*\nPromt the user to enter his information\nand when he has finished add the object to the array list.\n*/ \nprofiles.add(p);\n\nI'm okay until here.\nNext suppose that a user who has already a profile (which is already stored in the ArrayList), decides to press 2 to buy a new contract.\nI think that the most appropriate manner to do this is :\nProfile c = new MobilePhone();\n\nBut I will not have access to the appropriate user's profile in that way.\nSo I wonder how could I implement it. All I want is to associate the new contract with an already existed profile based on an id of the user.\nAny ideas on how to implement it?"

"Piecemeal bzcompression for large files in PHP",
"Creating bzip2 archived data in PHP is very easy thanks to its implementation in bzcompress. In my present application I cannot in all reason simply read the input file into a string and then call bzcompress or bzwrite. The PHP documentation does not make it clear whether successive calls to bzwrite with relatively small amounts of data will yield the same result as when compressing the whole file in one single swoop. I mean something along the lines of\n$data = file_get_contents('/path/to/bigfile');\n$cdata = bzcompress($data);\n\nI tried out a piecemeal bzcompression using the routines shown below\nfunction makeBZFile($infile,$outfile)\n{\n $fp = fopen($infile,'r');\n $bz = bzopen($outfile,'w');\n while (!feof($fp)) \n {\n $bytes = fread($fp,10240);\n bzwrite($bz,$bytes);\n }\n bzclose($bz);\n fclose($fp);\n}\n\nfunction unmakeBZFile($infile,$outfile)\n{\n $bz = bzopen($infile,'r');\n while (!feof($bz))\n {\n $str = bzread($bz,10240);\n file_put_contents($outfile,$str,FILE_APPEND);\n }\n}\n\nset_time_limit(1200);\nmakeBZFile('/tmp/test.rnd','/tmp/test.bz');\nunmakeBZFile('/tmp/test.bz','/tmp/btest.rnd'); \n\nTo test this code I did two things\n\nI used makeBZFile and unmakeBZFile to compress and then decompress a SQLite database - which is what I need to do eventually.\nI created a 50Mb filled with random data dd if=/dev/urandom of='/tmp.test.rnd bs=50M count=1\n\nIn both cases I performed a diff original.file decompressed.file and found that the two were identical.\nAll very nice but it is not clear to me why this is working. The PHP docs state that bzread(bzpointer,length) reads a maximum length bytes of UNCOMPRESSED data. If my code below is woring it is because I am forcing the bzwite and bzread size to 10240 bytes.\nWhat I cannot see is just how bzread knows how to fetch lenth bytes of UNCOMPRESSED data. I checked out the format of a bzip2 file. I cannot see tht there is anything there which helps easily establish the uncompressed data length for a chunk of the .bz file.\nI suspect there is a gap in my understanding of how this works - or else the fact that my code below appears to perform a correct piecemeal compression is purely accidental.\nI'd much appreciate a few explanations here."

"Update HTML when change is noticed in MySQL Database",

Let's say for instance that the value of a row in the database is 10, and that changes to 11, I need the page to automatically get this from the database, and update it on the site. Also, if possible, is there any way I could make the numbers \"pop out\" a little bit, when the actual data is changing?\n\n<div class=\"container hero-unit\">\n <h1>Test Data Change</h1>\n <p>231</p>\n <p>7</p>\n <p>14532</p>\n</div>\n\n\nLet' say that these numbers are fetched from the database, how would I use 'AJAX' to auto change this data when a change is made to the database?\n\nIf this is possible at all, I would appreciate every contribution....."

"When comparing characters, is ischar(x) && x == 'b' equivalent to strcmp(x, 'b')?",
"In MATLAB, I often use this to check if a variable contains a certain single character:\n\nif ischar(x) && x == 'b'\n\n\nto reduce clutter I'm thinking of changing it to this:\n\nif strcmp(x, 'b')\n\n\nbecause if x isn't a character or isn't equivalent to 'b', the comparison returns false as you would expect. Are these statements equivalent in this case or are there gotchas?\n\nMore info: x == 'b' isn't enough because this returns true when x == 98, but in certain cases (like validating user input), 98 may be invalid input while b is valid input. Also, the first one fails if x isn't a standard data type (if it's an object for example). Take this (stupid) example:\n\nx = table();\nx == 'b'\n\n\nThis throws an error because eq isn't defined for tables, but strcmp(x, 'b') returns 0 because it appears that strcmp also performs a type check. Whether or not this exception handling is desirable probably depends on the circumstances though."

I am running into problems when I have <= or >= in the xml file that needs to be converted to C++ code.\n\nFor example if I have (in .xml file)\n\n \n<Check>max(x,y) <= 20 </Check>\n \n\nand the .xsl file is \n\n\n\nif(<xsl:value-of select=\"Check\"/>\") {\n...\n}\n\n\n\nBut this does not compile as XML errors out on seeing <=. \n\nI tried &lt;= in xml file but I don't get <= in C++ file but I get &lt;=. To be user friendly I need to have <= in xml file rather than &lt;=.\n\nHow can I fix the code within if() condition so that I can handle all the escape characters in xml and properly output them to a C++ file?\n\nThanks\nAnand"

As soon as I try to go via my routers IP the client produces a mighty fine error message. All the usual suspects have been eliminated: Router Port forwarding is on, the firewall doesn't interfere (well, it still doesn't work when I turn it off), and canyouseeme.org says that it can establish a connection to my chosen port when the server runs.\n\nHere is the source code for the server, since I figured out it was possible to just go via the command line with a little telnetting.\nWhen I try to establish a connection, it just says Could not open connection to the host, on port 49163:Connection failed\n\nServer:\n\nimport java.net.*;\nimport java.io.*;\n\npublic class ChatServer {\n public static void main(String[] args) throws IOException {\n\n ServerSocket server = null;\n\n try {\n System.setProperty(\"java.net.preferIPv4Stack\" , \"true\");\n server = new ServerSocket(49163);\n } catch (IOException e) {\n System.err.println(\"Could not listen on port: 49163.\");\n System.exit(1);\n }\n\n Socket client = null;\n try {\n client = server.accept();\n } catch (IOException e) {\n System.err.println(\"Accept failed.\");\n System.exit(1);\n }\n\n PrintWriter out = new PrintWriter(client.getOutputStream(), true);\n BufferedReader in = new BufferedReader(newInputStreamReader(client.getInputStream()));\n String inputLine;\n String outputLine;\n\n out.println(\"Connection established\");\n while ((inputLine = in.readLine()) != null) {\n if (inputLine.equals(\"exit\")) {\n break;\n }\n outputLine = inputLine;\n out.println(outputLine);\n }\n out.close();\n in.close();\n client.close();\n server.close();\n System.out.println(\"Server offline\");\n }\n}\n\n\nOh yeah, preferIP4vStack was something I picked up on Stackoverflow, but it doesn't seem to work for me.\n\nFor some reason I'm not able to inlcude the code for the client, I keep getting messages about formatting, and I just can't figure it out. But the way I see it is that I'm not even able to connect via the command line (when I try to connect to the \"real\" IP), so the client doesn't have to get involved.

Having both in place allowed more than simply being able to \"undo\" changes made to an object and reverting it back to its retrieved (or uninitialized) values; the DataRowView object allowed a developer to begin a single editing operation on a DataRow in any state and undo those changes without undoing other changes that might have been made.\n\nFor example,\n\nDataRow retrieved as:\n\nCol1 | Col2\n----------------\n1 2\n\n\nDataRow Modified to:\n\nCol1 | Col2\n----------------\n1 3\n\n\nBeginEdit called on a DataRowView object for this row.\n\nDataRowView modified to:\n\nCol1 | Col2\n----------------\n2 3\n\n\nCancelEdit called on the DataRowView, reverting the values to\n\nCol1 | Col2\n----------------\n1 3\n\n\nSo the change was undone, but the values present before the edit--even though they were in-memory changes and not the retrieved values--are preserved.\n\nIs there any similar facility in the Entity Framework? I have a sneaking suspicion that the answer is \"no\", considering that it looks like an Entity uses simple backing variables for column values rather than a \"property bag\" approach like the DataRow uses (or WPF's DependencyProperty infrastructure uses)."

"Why android sdk hasn't support for many new elements?",
"In the last few days, i was trying to study the android's new Material Design. In the official doc, they suggest new element and various interactions.\n\nBut, for example, why don't they provide some simple support to raised/floating action buttons? Same to many other things, seems like they just want to suggest you the way to do it without providing real support on how to do them.\n\nThis way i end using tons of third libraries to support many of the new elements style and feels a bad idea.\n\nSorry for my bad english but just want to understand why can't they supply some support to the design they suggest."

"Preg_replace() removing all but the end of query",
