• How do I protect the trunk from hapless newbies?

  - by Michael Haren

  A coworker relayed the following problem, let's say it's fictional to protect the guilty: A team of 5-10 works on a project which is issue-driven. That is, the typical flow goes like this: a chunk of work (bug, enhancement, etc.) is created as an issue in the issue tracker The issue is assigned to a developer The developer resolves the issue and commits their code changes to the trunk At release time, the frozen, and heavily tested trunk or release branch or whatever is built in release mode and released The problem he's having is that a couple newbies made several bad commits that weren't caught due to an unfortunate chain of events. This was followed by a bad release with a rollback or flurry of hot fixes. One idea we're toying with: Revoke commit access to the trunk for newbies and make them develop on a per-developer branch (we're using SVN): Good: newbies are isolated and can't hurt others Good: committers merge newbie branches with the trunk frequently Good: this enforces rigid code reviews Bad: this is burdensome on the committers (but there's probably no way around it since the code needs reviewed!) Bad: it might make traceability of trunk changes a little tougher since the reviewer would be doing the commit--not too sure on this. Update: Thank you, everyone, for your valuable input. I have concluded that this is far less a code/coder problem than I first presented. The root of the issue is that the release procedure failed to capture and test some poor quality changes to the trunk. Plugging that hole is most important. Relying on the false assumption that code in the trunk is "good" is not the solution. Once that hole--testing--is plugged, mistakes by everyone--newbie or senior--will be caught properly and dealt with accordingly. Next, a greater emphasis on code reviews and mentorship (probably driven by some systematic changes to encourage it) will go a long way toward improving code quality. With those two fixes in place, I don't think something as rigid or draconian as what I proposed above is necessary. Thanks!

• About AMR audio file playing issue on different devices

  - by user352537

  I have got a quite strange problem here. I am developing an IM software and need to play audio files recorded by another client on Android. The same audio file I've got can be played with AVAudioPlayer on 3GS(IOS 4.2.1) device and simulator 4.2. But when I tried by play it on iPhone4(iOS 4.3.3), the function "play" always return NO. I also tried with two iPhone devices, the audio files recorded by iPhone client can be played on both 3GS and iPhone4. So I asked the Android developers about the record parameters they've used. They said that the "AudioEncoder" used by them was "DEFAULT". There are also some other parameters as following: **private AudioEncoder() {} public static final int DEFAULT = 0; /** AMR (Narrowband) audio codec */ public static final int AMR_NB = 1; /** @hide AMR (Wideband) audio codec */ public static final int AMR_WB = 2; /** @hide AAC audio codec */ public static final int AAC = 3; /** @hide enhanced AAC audio codec */ public static final int AAC_PLUS = 4; /** @hide enhanced AAC plus audio codec */ public static final int EAAC_PLUS = 5;** Does anybody know what's the matter?

• g++ on MacOSX doesn't work with -arch ppc64

  - by Albert

  I am trying to build a Universal binary on MacOSX with g++. However, it doesn't really work. I have tried with this simple dummy code: #include <iostream> using namespace std; int main() { cout << "Hello" << endl; } This works fine: % g++ test.cpp -arch i386 -arch ppc -arch x86_64 -o test % file test test: Mach-O universal binary with 3 architectures test (for architecture i386): Mach-O executable i386 test (for architecture ppc7400): Mach-O executable ppc test (for architecture x86_64): Mach-O 64-bit executable x86_64 However, this does not: % g++ test.cpp -arch i386 -arch ppc -arch x86_64 -arch ppc64 -o test In file included from test.cpp:1: /usr/include/c++/4.2.1/iostream:44:28: error: bits/c++config.h: No such file or directory In file included from /usr/include/c++/4.2.1/ios:43, from /usr/include/c++/4.2.1/ostream:45, from /usr/include/c++/4.2.1/iostream:45, from test.cpp:1: /usr/include/c++/4.2.1/iosfwd:45:29: error: bits/c++locale.h: No such file or directory /usr/include/c++/4.2.1/iosfwd:46:25: error: bits/c++io.h: No such file or directory In file included from /usr/include/c++/4.2.1/bits/ios_base.h:45, from /usr/include/c++/4.2.1/ios:48, from /usr/include/c++/4.2.1/ostream:45, from /usr/include/c++/4.2.1/iostream:45, from test.cpp:1: /usr/include/c++/4.2.1/ext/atomicity.h:39:23: error: bits/gthr.h: No such file or directory /usr/include/c++/4.2.1/ext/atomicity.h:40:30: error: bits/atomic_word.h: No such file or directory ...

• Pass checkbox values with Jquery to PHP and display result in div

  - by user1343955

  I want to filter realtime results with jQuery (just like on this site http://shop.www.hi.nl/hi/mcsmambo.p?M5NextUrl=RSRCH). So when someones checks a checkbox the results should update realtime (in a div). Now I'm a newbie with jQuery and I've tried lots of examples but I can't get it to work. Here's my code, could anyone tell what I'm doing wrong? Thank you very much! HTML <div id="c_b"> Kleur:<br /> <input type="checkbox" name="kleur[1]" value="Blauw"> Blauw <br /> <input type="checkbox" name="kleur[2]" value="Wit"> Wit <br /> <input type="checkbox" name="kleur[3]" value="Zwart"> Zwart <br /> <br /> Operating System:<br /> <input type="checkbox" name="os[1]" value="Android"> Android <br /> <input type="checkbox" name="os[2]" value="Apple iOS"> Apple iOS <br /> </div> <div id="myResponse">Here should be the result</div> jQuery function updateTextArea() { var allVals = []; $('#c_b :checked').each(function() { allVals.push($(this).val()); }); var dataString = $(allVals).serialize(); $.ajax({ type:'POST', url:'/wp-content/themes/u-design/filteropties.php', data: dataString, success: function(data){ $('#myResponse').html(data); } }); } $(document).ready(function() { $('#c_b input').click(updateTextArea); updateTextArea(); }); PHP //Just to see if the var passing works echo var_export($_POST);

• Protected and Private methods

  - by cabaret

  I'm reading through Beginning Ruby and I'm stuck at the part about private and protected methods. This is a newbie question, I know. I searched through SO for a bit but I couldn't manage to find a clear and newbie-friendly explanation of the difference between private and protected methods. The book gives two examples, the first one for private methods: class Person def initialize(name) set_name(name) end def name @first_name + ' ' + @last_name end private def set_name(name) first_name, last_name = name.split(/\s+/) set_first_name(first_name) set_last_name(last_name) end def set_first_name(name) @first_name = name end def set_last_name(name) @last_name = name end end In this case, if I try p = Person.new("Fred Bloggs") p.set_last_name("Smith") It will tell me that I can't use the set_last_name method, because it's private. All good till there. However, in the other example, they define an age method as protected and when I do fred = Person.new(34) chris = Person.new(25) puts chris.age_difference_with(fred) puts chris.age It gives an error: :20: protected method 'age' called for #<Person:0x1e5f28 @age=25> (NoMethodError) I honestly fail to see the difference between the private and protected methods, it sounds the same to me. Could someone provide me with a clear explanation so I'll never get confused about this again? I'll provide the code for the second example if necessary.

• Reduce function calls

  - by Curious2learn

  Hello, I profiled my python program and found that the following function was taking too long to run. Perhaps, I can use a different algorithm and make it run faster. However, I have read that I can also possibly increase the speed by reducing function calls, especially when it gets called repeatedly within a loop. I am a python newbie and would like to learn how to do this and see how much faster it can get. Currently, the function is: def potentialActualBuyers(setOfPeople,theCar,price): count=0 for person in setOfPeople: if person.getUtility(theCar) >= price and person.periodCarPurchased==None: count += 1 return count where setOfPeople is a list of person objects. I tried the following: def potentialActualBuyers(setOfPeople,theCar,price): count=0 Utility=person.getUtility for person in setOfPeople: if Utility(theCar) >= price and person.periodCarPurchased==None: count += 1 return count This, however, gives me an error saying local variable 'person' referenced before assignment Any suggestions, how I can reduce function calls or any other changes that can make the code faster. Again, I am a python newbie and even though I may possibly be able to use a better algorithm, it is still worthwhile learning the answer to the above question. Thanks very much.

• How to make NSView not clip its bounding area?

  - by Jeremy L

  I created an empty Cocoa app on Xcode for OS X, and added: - (void)applicationDidFinishLaunching:(NSNotification *)aNotification { self.view = [[NSView alloc] initWithFrame:NSMakeRect(100, 100, 200, 200)]; self.view.wantsLayer = YES; self.view.layer = [CALayer layer]; self.view.layer.backgroundColor = [[NSColor yellowColor] CGColor]; self.view.layer.anchorPoint = CGPointMake(0.5, 0.5); self.view.layer.transform = CATransform3DMakeRotation(30 * M_PI / 180, 1, 1, 1); [self.window.contentView addSubview:self.view]; } But the rotated layer's background is clipped by the view's bounding area: I thought since some version of OS X and iOS, the view won't clip the content of its subviews and will show everything inside and outside? On iOS, I do see that behavior, but I wonder why it shows up like that and how to make everything show? (I am already using the most current Xcode 4.4.1 on Mountain Lion). (note: if you try the code above, you will need to link to Quartz Core, and possibly import the quartz core header, although I wonder why I didn't import the header and it still compiles perfectly)

• Stuggling with webkit-transition in javascript

  - by Mungbeans

  I've tried a few variations of using webkit-transition that I've found from googling but I've not been able to get any to work. I have some audio controls that I make appear on a click event, they appear suddenly and jerky so I want to fade them in. The target browser is iOS so I am trying webkit extensions. This is what I currently have: <div id = "controls"> <audio id = "audio" controls></audio> </div> #controls { position:absolute; top: 35px; left:73px; height: 20px; width: 180px; display:none; } #audio { opacity:0.0; } audio.src = clip; audio.addEventListener('pause', onPauseOrStop, false); audio.addEventListener('ended', onPauseOrStop, false); audio.play(); audioControls.style.display = 'block'; audio.style.setProperty("-webkit-transition", "opacity 0.4s"); audio.style.opacity = 0.7; The documentation for webkit-transition says it takes effect on a change in the property, so I was assuming changing style.opacity in the last line would kick it off. The controls appear with an opacity of 0.7 but I want it to fade in and that animation isn't happening. I also tried this: #audio { opacity:0.0; -webkit-transition-property: opacity; -webkit-transition-duration: 1s; -webkit-timing-function: ease-in; } Also tried audio.style.webkitTransition = "opacity 1.4s"; from this posting How to set CSS3 transition using javascript? I can't get anything to work, I'm testing on iOS, Safari desktop and Chrome. Same non result on all of them.

• Updating an image's ImageUrl within a Repeater

  - by Django Reinhardt

  I hope someone can help me. It's a pretty newbie question, I'm afraid. I have an image inside a repeater, and I would like to change its IMAGEURL based on parameter that's being passed to it. <asp:Repeater ID="Repeater" runat="server"> <HeaderTemplate> <asp:Image ID="imgType" runat="server" /> </HeaderTemplate> <ItemTemplate> <%# Eval("DisplayName")%> </ItemTemplate> <SeparatorTemplate> <hr /> </SeparatorTemplate> </asp:Repeater> There is a SWITCH statement in the code behind that is altering the IMAGEURL depending on what's being passed to it. Inevitably, however, the images ID ("imgType") is not visible to the SWITCH statement (presumably because it's inside a REPEATER). Any suggestions on the best way to implement this would be greatly appreciated. Sorry for such a newbie question.

• Automating Excel 2010 using F#

  - by Clive Norman

  I have been searching for a FAQ to tell me how to open a Excel Workbook/Worksheet and also how to Save the File once I have finished. I notice that in most FAQ and all the books I have purchased on F# one is show how to create a new Workbook/Worksheet but is never shown how to either open or Save it. Being a newbie to F# I would very much appreciate it if anyone could kindly provide me with either an answer or perhaps a few pointers? Update As for why F# and not C# or VB? I am pleased to say that inspite of being a newbie (with the exception of Forth, VBA & Excel 2003, 2007 & 2010 and Visual Basic) I can do this in both VB, VBA & C# and since I've been retired on medical grounds, with plenty of time unfortunately on my hands, I like to continually set myself challenges to keep my little grey cells active and being a sucker for trying new languages....well! F# is now an intergral part of Visual Studio 2010 so I thought - why not. Consider this - if we are not willing to use or at least try a new languages - I would always be wonder if I might have prefer it to VBA, VB, C# ..... and if you look at it from another point of view, if no one is going to use it - why create it in the first place? I suppose you can say if cave men hadn't experimented and made fire by rubbing two sticks together - where would we be now and would matches have been invented? Although an complete answer would be good, I prefer a few pointers, to keep my challenge going. And lastly but not least - thank you for taking the trouble to respond!

• Read whole ASCII file into C++ std::string

  - by Arrieta

  Hello, I need to read a whole file into memory and place it in a C++ std::string. If I were to read it into a char, the answer would be very simple: std::ifstream t; int lenght; t.open("file.txt", "r"); // open input file t.seekg(0, std::ios::end); // go to the end length = t.tellg(); // report location (this is the lenght) t.seekg(0, std::ios::beg); // go back to the beginning buffer = new char[length]; // allocate memory for a buffer of appropriate dimension t.read(buffer, length); // read the whole file into the buffer t.close(); // close file handle // ... do stuff with buffer here ... Now, I want to do the exact same thing, but using a std::string instead of a char. I want to avoid loops, i. e., I don't want to: std::ifstream t; t.open("file.txt", "r"); std::string buffer; std::string line; while(t){ std::getline(t, line); // ... append line to buffer and go on } t.close() any ideas?

• Easy way to "organize"/"render"/"generate" HTML?

  - by Rockmaninoff

  Hi all, I'm a relative newbie to web development. I know my HTML and CSS, and am getting involved with Ruby on Rails for some other projects, which has been daunting but very rewarding. Basically I'm wondering if there's a language/backbone/program/solution to eliminate the copypasta trivialities of HTML, with some caveats. Currently my website is hosted on a school server and unfortunately can't use Rails. Being a newbie I also don't really know what other technologies are available to me (or even what those technologies might be). I'm essentially looking for a way to auto-insert all of my header/sidebar/footer/menu information, and when those need to be updated, the rest of the pages get updated. Right now, I have a sidebar that is a tree of all of the pages on my website. When I add a page, not only do I need to update the sidebar, I have to update it for every page in my domain. This is really inefficient and I'm wondering if there is a better way. I imagine this is a pretty widespread problem, but searching Google turns up too many irrelevant links (design template websites, tutorials, etc.). I'd appreciate any help. Oh, and I've heard of HAML as a way to render HTML; how would it be used in this situation?

• Loading more than 10 images on iPhone??

  - by SeniorLee

  I'm trying to add more than 10 pictures on ScrollView. NSUInteger i; for (i = 1; i <= numberOfImage; i++) { NSString *imageName = [NSString stringWithFormat:@"d%dimage%d.png", imageSection, i]; UIImage *image = [UIImage imageNamed:imageName]; UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; // setup each frame to a default height and width, it will be properly placed when we call "updateScrollList" CGRect rect = imageView.frame; rect.size.height = kScrollObjHeight; rect.size.width = kScrollObjWidth; imageView.frame = rect; imageView.tag = i; // tag our images for later use when we place them in serial fashion [scrollView addSubview:imageView]; [imageView release]; } This code is from Apple example and it works fine. But if the variable 'i' is bigger than 10, 'UIImage *image' is empty. The imageName seems to correct. But I don't know why it does not load image. Does anybody sees the problem?? And one more thing. If I do like that, does iOS controls memory automatically? I mean it's kind of wasting memory if all (more than 10) images are loaded on memory even they are not displayed. I've heard that iOS loads images only displayed on screen and free images those are not displayed. Is that right? Thanks for reading.

• Could not launch console app with xCode 4.4

  - by lp1756

  I have a project with two targets -- an iOS app and an OSX console app. The latter was created using Xcode File-New Target and selecting "Command Line Tool". This console app is used to prep a default database needed by the iOS app -- using CoreData. This has been working fine until I upgraded to Mountain Lion and xCode 4.4. Now when I try to run the command line tool I get a "Could Not Launch -- permission denied" error. I have tried playing around with signing certificates, to no avail. Interestingly if I create a new "hello, world" command line tool in a new project it works just fine -- and it is not signed at all. I checked the file and it has -rwxr-xr-x permission. In the debugger the app fails on startup even before it tries to access the moms. If I try to run this outside of the debugger at the command line, it ends with a kill 9 message. Any ideas would be greatly appreciated.

• Accessing Instance Variables from NSTimer selector

  - by Timbo

  Firstly newbie question: What's the difference between a selector and a method? Secondly newbie question (who would have thought): I need to loop some code based on instance variables and pause between loops until some condition (of course based on instance variables) is met. I've looked at sleep, I've looked at NSThread. In both discussions working through those options many asked why don't I use NSTimer, so here I am. Ok so it's simple enough to get a method (selector? ) to fire on a schedule. Problem I have is that I don't know how to see instance variables I've set up outside the timer from within the code NSTimer fires. I need to see those variables from the NSTimer selector code as I 1) will be updating their values and 2) will set labels based on those values. Here's some code that shows the concept… eventually I'd invalidate the timers based on myVariable too, however I've excluded that for code clarity. MyClass *aMyClassInstance = [MyClass new]; [aMyClassInstance setMyVariable:0]; [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(doStuff) userInfo:nil repeats:YES]; [NSTimer scheduledTimerWithTimeInterval:5.0 target:self selector:@selector(doSomeOtherStuff) userInfo:nil repeats:YES]; - (void) doStuff { [aMyClassInstance setMyVariable:11]; // don't actually have access to set aMyClassInstance.myVariable [self updateSomeUILabel:[NSNumber numberWithInt:aMyClassInstance.myVariable]]; // don't actually have access to aMyClassInstance.myVariable } - (void) doSomeOtherStuff { [aMyClassInstance setMyVariable:22]; // don't actually have access to set aMyClassInstance.myVariable [self updateSomeUILabel:[NSNumber numberWithInt:aMyClassInstance.myVariable]]; // don't actually have access to aMyClassInstance.myVariable } - (void) updateSomeUILabel:(NSNumber *)arg{ int value = [arg intValue]; someUILabel.text = [NSString stringWithFormat:@"myVariable = %d", value]; // Updates the UI with new instance variable values }

• Apache Cordova (Phonegap): is jsop needed for cross-site scripting?

  - by DEX

  I've just started using Apache Cordova. I have an library that makes calls (via ajax) to a soap server. When I run these on my local machine in chrome, I get cross site scripting errors when trying to make calls to the service. When I run the same exact code using the Cordova browser in the iOS emulator, the scripts seem to hit the server fine and the response data is received properly. So my question is how is the Cordova browser able to make these requests without cross-site scripting permissions & JSONP ? One thing I noticed is that when the request is sent from iOS, there is no "Origin" header. Is this allowing the Cordova browser to stealthily circumvent cross-site scripting requirements? Is it possible that the node.js server on the device (I believe this is how Cordova works) is manipulating the headers to allow this? I'd like to avoid enabling cross-site scripting on my site so I think this "feature" is nice, but I'm wondering if it's a security hole as well. Anyone have experience with this?

• C++ read registry string value in char*

  - by Sunny

  I'm reading a registry value like this: char mydata[2048]; DWORD dataLength = sizeof(mydata); DWORD dwType = REG_SZ; ..... open key, etc ReqQueryValueEx(hKey, keyName, 0, &dwType, (BYTE*)mydata, &dataLength); My problem is, that after this, mydata content looks like: [63, 00, 3A, 00, 5C, 00...], i.e. this looks like a unicode?!?!. I need to convert this somehow to be a normal char array, without these [00], as they fail a simple logging function I have. I.e. if I call like this: WriteMessage(mydata), it outputs only "c", which is the first char in the registry. I have calls to this logging function all over the place, so I'd better of not modify it, but somehow "fix" the registry value. Here is the log function: void Logger::WriteMessage(const char *msg) { time_t now = time(0); struct tm* tm = localtime(&now); std::ofstream logFile; logFile.open(filename, std::ios::out | std::ios::app); if ( logFile.is_open() ) { logFile << tm->tm_mon << '/' << tm->tm_mday << '/' << tm->tm_year << ' '; logFile << tm->tm_hour << ':' << tm->tm_min << ':' << tm->tm_sec << "> "; logFile << msg << "\n"; logFile.close(); } }

• Stop Rewrite htaccess create random pages

  - by Vistol

  Recently I saw in my Webmaster tools that some random sites are linking to my site. Actually this is not an big issue. The issue comes when the pages that are linked are not real pages because of my httaccess file. This is the htaccess code that Im running: <pre> #Options +FollowSymLinks RewriteEngine on RewriteRule ^([^/\.]+)/?$ index.php?id=$1 [L] RewriteRule ^([0-9]+)/(.*)$ index.php?id=$1 [L] </pre> So the real URLs would be: mysite.com/folder/999/TITLE-OR-NAME But cecause I only check the 1st folder ($1) which is an I numberD, this htaccess file is allowing hackers linking to my site with random URLs like: mysite.com/folder/999/TITLE-OR-NAME1 mysite.com/folder/999/TITLE-OR-NAME2 mysite.com/folder/999/TITLE-OR-NAME3 mysite.com/folder/999/TITLE-OR-NAME4 mysite.com/folder/999/TITLE-OR-NAME5 The worst part comes when google tells me that I am duplicating content!!! Actually I am not duplicating content, the htaccess is duplicating it for me. And yes I know, Im a bad newbie programmer but Id really appreciate your help with this cause Im struggling to find a solution but it never. Thank you very much for all your support to this newbie :)

• Pre-done SQLs to be converted to Rails' style moduls

  I am a Rails newbie and would really appreciate if someone converted these SQLs to complete modules for rails. I know its a lot to ask but I can't just use find_by_sql for all of them. Or can I? These are the SQLs (they run on MS-SQL): 1) SELECT STANJA_NA_DAN_POSTAVKA.STA_ID, STP_DATE, STP_TIME, STA_OPIS, STA_SIFRA, STA_POND FROM STANJA_NA_DAN_POSTAVKA INNER JOIN STANJA_NA_DAN ON(STANJA_NA_DAN.STA_ID=STANJA_NA_DAN_POSTAVKA.STA_ID) WHERE ((OSE_ID=10)AND (STANJA_NA_DAN_POSTAVKA.STP_DATE={d '2010-03-30'}) AND (STANJA_NA_DAN_POSTAVKA.STP_DATE<={d '2010-03-30'})) 2) SELECT ZIGI_OBDELANI.OSE_ID, ZIGI_OBDELANI.DOG_ID AS DOG_ID, ZIGI_OBDELANI.ZIO_DATUM AS DATUM, ZIGI_PRICETEK.ZIG_TIME_D AS ZIG_PRICETEK, ZIGI_KONEC.ZIG_TIME_D AS ZIG_KONEC FROM (ZIGI_OBDELANI INNER JOIN ZIGI ZIGI_PRICETEK ON ZIGI_OBDELANI.ZIG_ID_PRICETEK = ZIGI_PRICETEK.ZIG_ID) INNER JOIN ZIGI ZIGI_KONEC ON ZIGI_OBDELANI.ZIG_ID_KONEC = ZIGI_KONEC.ZIG_ID WHERE (ZIGI_OBDELANI.OSE_ID = 10) AND (ZIGI_OBDELANI.ZIO_DATUM = {d '2010-03-30'}) AND (ZIGI_OBDELANI.ZIO_DATUM <= {d '2010-03-30'}) AND (ZIGI_PRICETEK.ZIG_VELJAVEN < 0) AND (ZIGI_KONEC.ZIG_VELJAVEN < 0) ORDER BY ZIGI_OBDELANI.OSE_ID, ZIGI_PRICETEK.ZIG_TIME ASC 3) SELECT STA_ID, SUM(STP_TIME) AS SUM_STP_TIME, COUNT(STA_ID) FROM STANJA_NA_DAN_POSTAVKA WHERE ((STP_DATE={d '2010-03-30'}) AND (STP_DATE<={d '2010-03-30'}) AND (STA_ID=3) AND (OSE_ID=10)) GROUP BY STA_ID 4) SELECT DATUM, TDN_ID, TDN_OPIS, URN_OPIS, MOZNI_PROBLEMI, PRIHOD, ODHOD, OBVEZNOST, ZAKLJUCEVANJE_DATUM FROM OBRACUNAJ_DAN WHERE ((OSE_ID=10) AND (DATUM={d '2010-02-28'}) AND (DATUM<={d '2010-03-30'})) ORDER BY DATUM These SQLs are daily working hours and I got them as is. Also I got Database with it which (as you can see from the SQL-s) is not in Rails conventions. As a P.S.: 1)Things like STP_DATE={d '2010-03-30'}) are of course dates (in Slovenian date notation) and will be replaced with a variable (date), so that the user could choose date from and date to. 2) All of this data will be shown in the same page in the table,so maybe all in one module? Or many?; if this helps, maybe. So can someone help me? Its for my work and its my 1st project and I am a Rails newbie and the bosses are getting inpatient(they are getting quite loud actually) Thank you very very much!

• (C++) Loading a file into a vector

  - by Alden

  This is probably a simple question, however I am new to C++ and I cannot figure this out. I am trying to load a binary file and load each byte to a vector. This works fine with a small file, but when I try to read larger than 410 bytes the program crashes and says: This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. I am using code::blocks on windows. This is the code: #include <iostream> #include <fstream> #include <vector> using namespace std; int main() { std::vector<char> vec; std::ifstream file; file.exceptions( std::ifstream::badbit | std::ifstream::failbit | std::ifstream::eofbit); file.open("file.bin"); file.seekg(0, std::ios::end); std::streampos length(file.tellg()); if (length) { file.seekg(0, std::ios::beg); vec.resize(static_cast<std::size_t>(length)); file.read(&vec.front(), static_cast<std::size_t>(length)); } int firstChar = static_cast<unsigned char>(vec[0]); cout << firstChar <<endl; return 0; } Thank you for your help!

• C++: how serialize/deserialize objects without any library?

  - by Winte Winte

  I try to understand how serializing/deserializing works in c++, so I want to do that without any libs. But I really stuck with that. I start with simple objects but when I try to deserilize a vector I understand that I can't get a vector without if I don't write it size before. Moreover, I don't know which format of file I should choose because if digits will be existed before size of vector I haven't chance to read it right. However it is only the vector but I also want to do that with classes and map container. My task is serialize/deserialize a objects as this: PersonInfo { unsigned int age_; string name_; enum { undef, man, woman } sex_; } Person : PersonInfo { vector<Person> children_; map<string, PersonInfo> addrBook_; } Currently I know how to serialize simple objects in way as this: vector<PersonInfo> vecPersonInfo; vecPersonInfo.push_back(*personInfo); vecPersonInfo.push_back(*oneMorePersonInfo); ofstream file("file", ios::out | ios::binary); if (!file) { cout<<"can not open file"; } else { vector<PersonInfo>::const_iterator iterator = vecPersonInfo.begin(); for (; iterator != vecPersonInfo.end(); iterator++) { file<<*iterator; } Could you please suggest how I can do this for this conplex object or a good tutorial that explain it clearly?

• Aptitude command on fedora

  - by danielrutledge

  Hi, linux newbie here. I'm running Fedora 12 and I have a script for Ubuntu installing a bunch of packages using aptitude. I tried installing the packages using yum, but most of them aren't available. The packages aren't very new or complicated stuff, is there any way get packages through aptitude on fedora? Or am I just going to have to find the Fedora equivalent of each package manually, for example the first package installed is g++ and of course this has a fedora equivalent.
