  • Hibernate HQL to basic SQL

    - by CC
    Hello everybody, I working on a project with Hibernate and we need to replace Hibernate with some "home made persistence" stuff. The idea is that the project is big enough, and we have many HQL queries. The problem is with the queries like select a,b from table1, table2 on t1.table1=t2.table2 Basically all joins are not supported by our "hand made persistence" stuff. What I would need, is to be able to do some sort of transcoder, which will take as a input the HQL queries and output some SQL, but the basic SQL without joins, something like (a dumb example) select a from table1 where t1 IN ( select b from table2) I hope you get the idea. My persistence layer does not supports joins. Does anybody has any idea about something like that? Some framework, or something? Thanks alot everybody. C.C.

  • How to enable BDS2006's C++ WARN & TRACE macros.

    - by Psychic
    I am trying to find out how to enable (& use) Borland's WARN & TRACE macros. My starting point was this link: http://bcbjournal.org/articles/vol2/9809/Debugging_with_diagnostic_macros.htm?PHPSESSID=37bf58851bfeb5c199d1af31d7b2e7ff However, that appears to be for BCB5, and not the 2006 Borland Developer Studio. I've set the two defines (__WARN & __TRACE) I've included the .h file () I've added some macros, and everything compiles & links fine. But when I run the application (in DEBUG mode), no debug output file is created. What am I missing here?

  • how to get memory dump after blue screen

    - by user464164
    I'm getting a lovely BSOD on bootup (STOP: 0x0000007E) from a driver I'm writing, and would like to load up the memory dump for analysis. However, it's not getting dumped anywhere. Everything is setup correctly in the Startup and Recovery settings, but I get no dump file, and nothing in the event log stating a dump has taken place. It looks like a dump is not even occurring... I know the exact line of code causing it (a call to IoAttachDevice()), but am not sure why, and would like to view the DbgPrint output to see where exactly it's failing. Could Windows possibly be crashing before the dumping functionality is set up? If so, how do I get access to the state of the machine when the failure occurs? UPDATE: Other possibly useful information: I'm running Windows XP through VirtualBox on a Linux host.

  • Voice Control iOS

    - by Marc Tanis
    I would like to build a simple reader app for the iPad 2 that would allow users to navigate/read via voice controls. The app would allow the user to enter a mode where the microphone was live and listened for predefined keywords like 'down', 'up', 'next', 'back', 'home', etc. I don't want to reinvent the wheel on this so I'm just wondering first, if someone has done this already and if not, are there any good tutorials or SDKs available to help with recording someone's voice, and then comparing future output to see if it matches, or just dealing with the microphone in general?

  • Invisible Delimiter for Strings in HTML

    - by noah
    I need a way to identify certain strings in HTML markup. I know what the strings are, but it is possible that they could be substrings of other strings in the document. To find them, I output a special delimiter character (currently using \032). On page load, we go through the HTML and record the location of the strings, and remove the delimiter. Unfortunately, most browsers show the delimiter character until we can find and remove them all. I'd like to avoid that if possible. Is there a character or string that will be preserved in the HTML content (so a comment wont work) but wont be visible to the user? It also needs to be something that is fairly unlikely to appear next to a string, so something like &nbsp; wouldn't work either. EDIT: Sorry, I forgot to mention that the strings will be in attributes, so any sort of tag wont work.

  • WinMain not called before main (C/C++ Program Entry Point Issue)

    - by BT
    I was under the impression that this code #include <windows.h> #include <stdio.h> int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLine, int iCmdShow) { printf("WinMain\n"); return 0; } int main() { printf("main\n"); return 0; } would output WinMain, but of course nothing ever works how you expects. Anyways, could somebody please tell me how to get this program to run WinMain first (I do have a reason for using both). I'm running windows 7 with mingw if that helps anything.

  • Customizing Log4j to filter PatternLayout

    - by JavaScriptDude
    Greetings, I have just starting migrating to WLS 10.x and have noticed that the thread name [%t] for WL is quite verbose and more informative than I need for my deployment needs. Ultimately, I only care about the thread ID but WL gives me this:    [ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)' ~ Does anybody know if there is a way in log4j to write a custom filter that will allow me to override PatternLayout so I can parse the WLS Thread Name to just output the thread ID which in this case above is 0. I'd rather extend then customize as it makes upgrading libraries so much easier. Thanks :) - JsD

  • Python - Flatten a dict of lists into unique values?

    - by Jonathan Vanasco
    I have a dict of lists in python: content = {88962: [80, 130], 87484: [64], 53662: [58,80]} I want to turn it into a list of the unique values [58,64,80,130] I wrote a manual solution, but it's a manual solution. I know there are more concise and more elegant way to do this with list comprehensions, map/reduce , itertools , etc. anyone have a clue ? content = {88962: [80, 130], 87484: [64], 53662: [58,80]} result = set({}) for k in content.keys() : for i in content[k]: result.add(i) # and list/sort/print just to compare the output r2 = list( result ) r2.sort() print r2

  • In python, is there anyway to have a variable be a different random number everytime?

    - by woah113
    Basically I have this: import random variable1 = random.randint(13, 19) And basically what that does is assign variable1 a random number between 13 and 19. Great. But, what I want it to do is assign a different random number between 13 and 19 to that variable every time it is called. Is there anyway I can do this? If I'm not being clear enough here's an example: import random variable1 = random.randint(13, 19) print(variable1) print(variable1) print(variable1) And the output I want would look something like this: ./script.py 15 19 13 So yeah, anyway I could do this in python? (More specifically python3. but the answer would probably be similar to a python2 answer)

  • [PHP] - Lowering script memory usage in a "big" file creation

    - by Riccardo
    Hi there people, it looks like I'm facing a typical memory outage problem when using a PHP script. The script, originally developed by another person, serves as an XML sitemap creator, and on large websites uses quite a lot of memory. I thought that the problem was related due to an algorithm holding data in memory until the job was done, but digging into the code I have discovered that the script works in this way: open file in output (will contain XML sitemap entries) in the loop: ---- for each entry to be added in sitemap, do fwrite close file end Although there are no huge arrays or variables being kept in memory, this technique uses a lot of memory. I thought that maybe PHP was buffering under the hood the fwrites and "flushing" data at the end of the script, so I have modified the code to close and open the file every Nth record, but the memory usage is still the same.... I'm debugging the script on my computer and watching memory usage: while script execution runs, memory allocation grows. Is there a particular technique to instruct PHP to free unsed memory, to force flushing buffers if any? Thanks

  • C# is there a problem with division?

    - by Tom
    This is a piece of my code, it is called every second, after about 10 seconds the values start to become weird (see below): double a; double b; for (int i = 0; i < currAC.Length; i++ ) { a = currAC[i]; b = aveACValues[i]; divisor = (a/b); Console.WriteLine("a = " + a.ToString("N2") + "\t" + "b = " + b.ToString("N2")); Console.WriteLine("divisor = " + divisor); Console.WriteLine("a+b = " + (a+b)); } and the output: a = -0.05 b = 0.00 divisor = 41 a+b = -0.0524010372273268 currAC and aveACValues are double[] what on earth is going on???? The addition result is correct every time, but the division value is wrong, yet it is reading a and b correctly?? EDIT: '41' is the value of the first calculation, ie when a = currAC[0], but this should not remain???

  • How can I possibly sort this in JavaScript?

    - by orokusaki
    I've been pounding my head on the wall trying to figure out how to sort this in JavaScript (I have to work with it in this format unfortunately). I need to sort it based on Small, Medium, Large, XL, XXL (Small ranking the highest) in each variationValues size field. The problem is that I need to sort the variationCosts and variationInventories at the same time to match the new order (since each value in order corresponds to the values in the other fields :( Input I have to work with var m = { variationNames: ["Length", "Size" ], variationValues: [ ["26.5\"", "XXL"], ["25\"", "Large"], ["25\"", "Medium"], ["25\"", "Small"], ["25\"", "XL"], ["25\"", "XXL"], ["26.5\"", "Large"], ["26.5\"", "Small"], ["26.5\"", "XL"] ], variationCosts: [ 20.00, 20.00, 20.00, 20.00, 20.00, 20.00, 20.00, 20.00, 20.00 ], variationInventories: [ 10, 60, 51, 10, 15, 10, 60, 10, 15 ], parentCost: 20.00 }; Desired output var m = { variationNames: ["Length", "Size" ], variationValues: [ ["25\"", "Small"], ["26.5\"", "Small"], ["25\"", "Medium"], ["25\"", "Large"], ["26.5\"", "Large"], ["25\"", "XL"], ["26.5\"", "XL"] ["25\"", "XXL"], ["26.5\"", "XXL"], ], variationCosts: [ 20.00, 20.00, 20.00, 20.00, 20.00, 20.00, 20.00, 20.00, 20.00 ], variationInventories: [ 10, 10, 51, 60, 15, 15, 15, 10, 10 ], parentCost: 20.00 };

  • Is Sphinx better than LaTex in writing manuals/books?

    - by Masi
    Only a few people recommended to use Sphinx at the beginning of the year. Sphinx has developed rather fast recently. I noted today that Sage has made a change from direct editing with LaTex to Sphinx. This is evident in William Stein's answer on 2nd April about Sage's tutorial The tutorial is not a latex document anymore. It's an entirely different Sphinx document that can output pdf. It suggests me that Sphinx may be at a level such that it is suitable for me. Is Sphinx better than LaTex in writing manuals/books?

  • Help with Regex statement in Ruby

    - by user336777
    I have a string called 'raw'. I am trying to parse it in ruby in the following way: raw = "HbA1C ranging 8.0—10.0%" raw.scan /\d*.?\d+[ ](-+|\342\200\224)[ ]\d*.?\d+/ The output from the above is []. I think it should be: ["8.0—10.0"]. Does anyone have any insight into what is wrong with the above regex statement? Note: \342\200\224 is equal to '—'. The piece that is not working is: (-+|\342\200\224) I think it should be equivalent to saying, match on 1 or more '-' OR match on the string \342\200\224. Any help would be greatly appreciated it!

  • Replacing a column in CSV file with another in bash

    - by user2525881
    I have a csv file with a number of columns. I am trying to replace the second column with the second to last column from the same file. For example, if I have a file, sample.csv 1,2,3,4,5,6 a,b,c,d,e,f g,h,i,j,k,l I want to output: 1,5,3,4,5,6 a,e,c,d,e,f g,k,i,j,k,l Can anyone help me with this task? Also note that I will be discarding the last two columns afterwards with the cut function so I am open to separating the csv file to begin with so that I can replace the column in one csv file with another column from another csv file. Whichever is easier to implement. Thanks in advance for any help.

  • Question about pipe in Perl

    - by Uri
    The following code is working sort of fine: open( PIPE, '-|', 'ant' ); for( <PIPE> ) { print; } However, it doesn't do what I want. Since the Ant build can take 5 minutes, I would like to see the output line by line. Instead, I'm getting the entire input at the end of the process. Looking at it with the Perl debugger, Perl waits at the 'for' statement, until Ant terminates. Why is that?

  • MySQL Cluster data nodes - slow SELECTs

    - by Boyan Georgiev
    Hi to all. First off, I'm new to MySQL Cluster. This is my pain: I've managed to setup a MySQL Cluster with two data nodes, two SQL nodes and one management server. Everything works pretty well, except the following: my data nodes are spread across an intranet link which incurs latency into communications between the data nodes. Apparently, due to MySQL Cluster's internal partitioning schemes, when my PHP application pulls data from the cluster via SELECT queries, parts of the data are pulled from both data nodes. This makes the page appear onscreen REALLY slowly. If I bring one data node offline, the data can only be pulled from that single remaining data node, and thus, the final result (HTML output) appears on the screen in a very timely fashion. So, my question is this: can the data nodes/cluster be told to pull data from partitions stored only on a particular data node?

  • Constructor Type Coercion in C++

    - by Robert Mason
    Take the following class: class mytype { double num; public: mytype(int a) { num = sqrt(a); } void print() { cout << num; } } Say there is a method which takes a mytype: void foo(mytype a) { a.print(); } Is it legal c++ (or is there a way to implement this) to call foo(4), which would (in theory) output 2? From what I can glean you can overload type casts from a user defined class, but not to. Can constructor do this in a standards-compliant manner (assuming, of course, the constructor is not explicit). Hopefully there is a way to in the end have this legal: int a; cin >> a; foo(a); Note: this is quite obviously not the actual issue, but just an example for posting purposes. I can't just overload the function because of inheritance and other program-specific issues.

  • Which is more efficient/faster when calling a cached image?

    - by andufo
    Hi, i made an image resizer in php. When an image is resized, it caches a new jpg file with the new dimensions. Next time you call the exact img.php?file=hello.jpg&size=400 it checks if the new jpg has already been created. If it has NOT been created yet, it creates the file and then prints the output (cool). If it ALREADY exists, no new file needs to be generated and instead, it just calls the already cached file. My question is regarding the second scenario. Which of these is faster? redirecting: header('Location: cache/hello_400.jpg');die(); grabbing data and printing the cached file: $data = file_get_contents('cache/hello_400.jpg'); header('Content-type: '.$mime); header('Content-Length: '.strlen($data)); echo $data; Any other ways to improve this?
