• When is Googling it wrong?

  - by Drahcir

  I've been going through Stack Overflow for quite a bit now and noticed certain people (usually experienced programmers) frown upon Googling (researching) certain problems. Since I myself tend to use Google quite a bit to solve certain programming related issues I found certain comments rather demoralising. Now some of you may have come here trigger happy to delete this post but I needed some clarification. I usually Google things that usually syntax related that I would have never figured out on my own. For example I once wondered how to access the properties of a class that I didn't have a direct relationship to. So after a bit of research I discovered reflection and got what I wanted. Now in another scenario is learning a new language, in my case Silverlight were it differs in certain aspects of .NET compared to say ASP.NET. A few weeks ago I had no idea how to load another Silverlight page (usercontrol) and had to Google my way to the solution which I found wasn't as simple as I had imagined. In scenario three is were I myself frown up, that is just stealing a huge chunk of code to avoid doing the work yourself, for example paging a HTML table using JavaScript, where one just copies and pastes the JavasSript code without as much as trying to understand how it works. I do admit I have done this once or twice before for trivial tasks that had very little time limit and weren't all that important but most of the time still have to throw away what I found because it took too much time to adapt it and get what I wanted out of it. In the last scenario, I sometimes have a piece of code that I would be really unhappy about, as in I find it sloppy or too overcomplicated and try to look on the Internet to see other ways to tackle the same problem, let's say filtering through a table. With the knowledge I acquire I learned new coding practices that help me work more efficiently like "Do not repeat yourself" and such. Now in your opinion when do you find it wrong to use Google (or any other researching tool) to find a solution to your problem?

• PHP: problem rendering large images (error 321)

  - by JP19

  Hi ... its me again with a php problem :) Following is part of my PHP script which is rendering JPEG images. ... $tf=$requested_file; $image_type="jpeg"; header("Content-type: image/${image_type}"); $CMD="\$image=imagecreatefrom${image_type}('$tf'); image${image_type}(\$image);"; eval($CMD); exit; ... There is no syntactical error, because above code is working fine for small images, but for large images, it gives: Error 321 (net::ERR_INVALID_CHUNKED_ENCODING): Unknown error. in the browser. To be sure, I created two images using imagemagick from same source image - one resized to 10% of original and other 90%. http://mostpopularsports.net/images/misc/ttt10.jpg works http://mostpopularsports.net/images/misc/ttt90.jpg gives Error 301 in the browser. There is a related question with solution posted by OP here Error writing content through Apache. but I cannot understand how to make the fix. Can someome help me with it? I have looked at the headers in Chrome. For the first request, everything is fine. For the second request - the request headers are all garbled. Both images are jpeg (as they are created from imagemagick. But still to be sure I checked): misc/ttt10.jpg: JPEG image data, JFIF standard 1.01 misc/ttt90.jpg: JPEG image data, JFIF standard 1.01 Finally, the way I fixed is, remove the Transfer-Encoding: chunked header from the response. [This header was sent by apache only when the data was large enough]. (I had an internal proxy, so did it in the proxy script - otherwise one may need to do it in apache settings). There were some good answers and I have selected the one that helped me solve the problem best. thanks JP

• managing classes when everything is relative to a user in nhibernate (orm)

  - by Schotime

  Firstly I have three entities. Users, Roles, Items A user can have multiple Roles. An item gets assigned to one or more roles. Therefore a user will have access to a distinct set of items. Now there is a few ways I can see this working. There is a Collection on Users which has Roles via a many-to-many assoc. Then each Role in this collection will have its own collection of Items. So for each user I would have to get the User (using nhib and fetch the roles and items with it) then either do a selectMany on the Items in each Role to get all the Items for the user or do a couple of foreach's to port the data to a view or dto model. Create a db trigger to automatically insert into another table that just has the relationship between user and items so that on my User entity I only have a Items collections which has all the items assigned to me. Some other way that i can't think of yet, because I'm new to nHibernate. Now i know that the trigger doesn't feel right but I'm not sure how to do this. We also have some hierarchy later where a user may be in charge of a group of users. If anyone could shed some light on how they go about these scenarios in nhibernate or another orm that would be great, or point be in a direction. I know that in the past you would have to enter all combinations into a table so that the query worked, but when you know sql its not too bad. If you need any other info then let me know. Cheers

• MTD Expression on a single column - SSRS

  - by Eric

  I need a bit of help here. I have been unable to create an 'Month To Date' expression to a single column on SSRS. I tested the following expression from a similar question in the forum, but it gives me a squiggly line below the variable 'd' =IIF(Fields!CreateDate.Value >= DateAdd(d,-7,Today()), Sum(Fields!Sales.Value), 0) If I run it, of course I got an error telling me that 'd' is not declared. ;) I changed it to ... DateAdd("d",-7,Today()), Sum(Fields!Sales.Value) ... following the example and the squiggly goes below the brackets of "today()" and needless to say it...but still not working. I tried a Dateadd(mm..Datediff ... and still nothing. My report has the following columns: Country | CustomerName | Sales | InvNotProcessed | Open Order | Orders | TotalbyCust What I need is to show the new MTD sales only in the column named "Sales" while the other three shows the rest of the query, which should be open as some orders may take quite a while to manufacture and invoice. the last column sums the totals of all other columns. Any help will be much appreciated. Regards, Eric

• Getting moved out of a development job

  - by Jay

  I'm a year out of college and I started my first dev job at a small (<15 people) company several months ago. It was an internship position that recently turned full time. The position started out as development but for full time I got offered a grab bag of positions: qa, docs, call support and some dev work. It's clear that my employers feel I am lacking dev skills, which is true. I did not major in CS in college and did not have much dev experience. However, I'm convinced that I can be a good developer and I will be a good developer once given the chance to write lots of code. My question is simple: what should I do? As I see it, there are two options. Work hard in the non-dev duties so that my employers may eventually give me significant dev responsibilities. Look for a new job where I will be a developer first and an all purpose guy second (if at all). Thanks guys.

• How can I get HTML to link to a browser (or system) specified URL?

  - by MrHatken

  Hi All, I'd like to be able to create a "HTML link" that the user can click on and be taken to an URL (location) specified either in the browser (preferences?) or system environment. Is this possible? Any suggestions on how to do it please? For example, it may look something like this (or alternatively it could be a clickable image or even a submit button): "Click here to go to your preferred news site." When the user clicks on "here" the browser would go to a location specified not in the HTML but somehow in the browser (preferences?) or some system environment variable (OS specific etc.) Of course, the user would have to set up this preference or environment variable (or have some local application or better Web page that could set it - when approved by the user). This is sort of like most OS these days allow you to set "preferred app" for image processing or playing media. I would like to set preferred Web sites for certain tasks. Thanks for any suggestions. Hopefully with Javascript and modern browsers and perhaps HTML 5 something like this is possible. Cheers, Ashley.

• Why cant we create Object if constructor is in private section?

  - by Abhi

  Dear all I want to know why cant we create object if the constructor is in private section. I know that if i make a method static i can call that method using <classname> :: <methodname(...)>; But why cant we create object is my doubt... I also know if my method is not static then also i can call function by the following... class A { A(); public: void fun1(); void fun2(); void fun3(); }; int main() { A *obj =(A*)malloc(sizeof(A)); //Here we can't use new A() because constructor is in private //but we can use malloc with it, but it will not call the constructor //and hence it is harmful because object may not be in usable state. obj->fun1(); obj->fun2(); obj->fun3(); } So only doubt is why cant we create object when constructor is in private section? Thanks in advance

• need an empty XML while unmarshalling a JAXB annotated class

  - by sswdeveloper

  I have a JAXB annotated class Customer as follows @XmlRootElement(namespace = "http://www.abc.com/customer") public class Customer{ private String name; private Address address; @XmlTransient private HashSet set = new HashSet<String>(); public String getName(){ return name; } @XmlElement(name = "Name", namespace = "http://www.abc.com/customer" ) public void setName(String name){ this.name = name; set.add("name"); } public String getAddress(){ return address; } @XmlElement(name = "Address", namespace = "http://www.abc.com/customer") public void setAddress(Address address){ this.address = address; set.add("address"); } public HashSet getSet(){ return set; } } I need to return an empty XML representing this to the user, so that he may fill the necesary values in the XML and send a request So what I require is : <Customer> <Name></Name> <Address></Address> </Customer> If i simply create an empty object Customer cust = new Customer() ; marshaller.marshall(cust,sw); all I get is the toplevel element since the other fields of the class are unset. What can I do to get such an empty XML? I tried adding the nillable=true annotation to the elements however, this returns me an XML with the xsi:nil="true" which then causes my unmarshaller to ignore this. How do I achieve this?

• Creating a C++ DLL and then using it in C#

  - by Major

  Ok I'm trying to make a C++ DLL that I can then call and reference in a c# App. I've already made a simple dll using the numberous guides out there, however when I try to reference it in the C# app I get the error Unable to load DLL 'SDES.dll': The specified module could not be found.

• SELECT SQL Variable - should i avoid using this syntax and always use SET?

  - by Sholom

  Hi All, This may look like a duplicate to here, but it's not. I am trying to get a best practice, not a technical answer (which i already (think) i know). New to SQL Server and trying to form good habits. I found a great explanation of the functional differences between SET @var = and SELECT @var = here: http://vyaskn.tripod.com/differences_between_set_and_select.htm To summarize what each has that the other hasn't (see source for examples): SET: ANSI and portable, recommended by Microsoft. SET @var = (SELECT column_name FROM table_name) fails when the select returns more then one value, eliminating the possibility of unpredictable results. SET @var = (SELECT column_name FROM table_name) will set @var to NULL if that's what SELECT column_name FROM table_name returned, thus never leaving @var at it's prior value. SELECT: Multiple variables can be set in one statement Can return multiple system variables set by the prior DML statement SELECT @var = column_name FROM table_name would set @var to (according to my testing) the last value returned by the select. This could be a feature or a bug. Behavior can be changed with SELECT @j = (SELECT column_name FROM table_name) syntax. Speed. Setting multiple variables with a single SELECT statement as opposed to multiple SET/SELECT statements is much quicker. He has a sample test to prove his point. If you could design a test to prove the otherwise, bring it on! So, what do i do? (Almost) always use SET @var =, using SELECT @var = is messy coding and not standard. OR Use SELECT @var = freely, it could accomplish more for me, unless the code is likely to be ported to another environment. Thanks

• SQL problem - select accross multiple tables (user groups)

  - by morpheous

  I have a db schema which looks something like this: create table user (id int, name varchar(32)); create table group (id int, name varchar(32)); create table group_member (foobar_id int, user_id int, flag int); I want to write a query that allows me to so the following: Given a valid user id (UID), fetch the ids of all users that are in the same group as the specified user id (UID) AND have group_member.flag=3. Rather than just have the SQL. I want to learn how to think like a Db programmer. As a coder, SQL is my weakest link (since I am far more comfortable with imperative languages than declarative ones) - but I want to change that. Anyway here are the steps I have identified as necessary to break down the task. I would be grateful if some SQL guru can demonstrate the simple SQL statements - i.e. atomic SQL statements, one for each of the identified subtasks below, and then finally, how I can combine those statements to make the ONE statement that implements the required functionality. Here goes (assume specified user_id [UID] = 1): //Subtask #1. Fetch list of all groups of which I am a member Select group.id from user inner join group_member where user.id=group_member.user_id and user.id=1 //Subtask #2 Fetch a list of all members who are members of the groups I am a member of (i.e. groups in subtask #1) Not sure about this ... select user.id from user, group_member gm1, group_member gm2, ... [Stuck] //Subtask #3 Get list of users that satisfy criteria group_member.flag=3 Select user.id from user inner join group_member where user.id=group_member.user_id and user.id=1 and group_member.flag=3 Once I have the SQL for subtask2, I'd then like to see how the complete SQL statement is built from these subtasks (you dont have to use the SQL in the subtask, it just a way of explaining the steps involved - also, my SQL may be incorrect/inefficient, if so, please feel free to correct it, and point out what was wrong with it). Thanks

• [Apache] Creating rewrite rules for multiple urls in the same folder

  - by DavidYell

  I have been asked by our client to convert a site we created into SEO friendly url format. I've managed to crack a small way into this, but have hit a problem with having the same urls in the same folder. I am trying to rewrite the following urls, /review/index.php?cid=intercasino /review/submit.php?cid=intercasino /review/index.php?cid=intercasino&page=2#reviews I would like to get them to, /review/intercasino /submit-review/intercasino /review/intercasino/2#reviews I've almost got it working using the following rule, RewriteRule (submit-review)/(.*)$ review/submit.php?cid=$2 [L] RewriteRule (^review)/(.*) review/index.php?cid=$2 The problem, you may already see, is that /submit-review rewrites to /review, which in turn gets rewritten to index.php, thus my review submission page is lost in place of my index page. I figured that putting [L] would prevent the second rule being called, but it seems that it rewrites both urls in two seperate passes. I've also tried [QSE], and [S=1] I would rather not have to move my files into different folders to get the rewriting to work, as that just seems too much like bad practise. If anyone could give me some pointers on how to differentiate between these similar urls that would be great! Thanks (Ref: http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html)

• Generate unique ID from multiple values with fault tolerance

  - by ojreadmore

  Given some values, I'd like to make a (pretty darn) unique result. $unique1 = generate(array('ab034', '981kja7261', '381jkfa0', 'vzcvqdx2993883i3ifja8', '0plnmjfys')); //now $unique1 == "sqef3452y"; I also need something that's pretty close to return the same result. In this case, 20% of the values is missing. $unique2 = generate(array('ab034', '981kja7261', '381jkfa0', 'vzcvqdx2993883i3ifja8')); //also $unique2 == "sqef3452y"; I'm not sure where to begin with such an algorithm but I have some assumptions. I assume that the more values given, the more accurate the resulting ID – in other words, using 20 values is better than 5. I also assume that a confidence factor can be calculated and adjusted. What would be nice to have is a weight factor where one can say 'value 1 is more important than value 3'. This would require a multidimensional array for input instead of one dimension. I just mashed on the keyboard for these values, but in practice they may be short or long alpha numeric values.

• Problem in displaying image in FireFox

  - by Param-Ganak

  Hello friends, I have a JSP page on which I have a div tag in which there is a a IMG tag. Using this IMG tag I want to show an image in it. Here the source path of an image is comes from database so I assigned a JSP variable using JSP scriplet. This JSP variable have the source path of an image. This path of image may be of different machine or of same machine i.e. images are stored on different machine or on same machine i.e. on local machine on different drive. The problem is that how to give path of image stored on different machine as well as on same machine. I have tried different ways like by giving ip address of that machine. Here is the path that of local machine where the image is stored img src= file:\localhost\D:\ScannedSheets\testproj/batch1/IMG001.jpg style="z-index:1; position:absolute; top:0; left:0; width:850; height:1099" With this syntax the image is visible in Internet Explorer but With the same syntax Its not visible in FireFox, Google Chrome etc. Please Guide me in friends. Also tell me that how to give path of the image stored on different machine which works In Internet Explorer, FireFox, Google chrome etc.

• Troubleshooting multiple GET variables In PHP

  - by V413HAV

  This may be a very simple question but I don't what's the wrong thing am doing here... To explain you clearly, I've set a real simple example below: <ul> <li><a href="test.php?link1=true">Link 1</a></li> <li><a href="test.php?link2=true">Link 2</a></li> <li><a href="test.php?link3=true">Link 3</a></li> </ul> <?php if(isset($_GET['link1'])) { if(($_GET['link1']) == 'true') { echo 'This Is Link 1'; } } if(isset($_GET['link2'])) { if(($_GET['link2']) == 'true') { echo 'This Is Link 2'; } } if(isset($_GET['link3'])) { if(($_GET['link3']) == 'true') { echo 'This Is Link 3'; } } ?> This is a test.php page, here I've set 3 different arguments for $_GET, and show contents accordingly, now everything works perfect, the only thing am not understanding is how to block this kind of url say if user clicks on link 1 the url will be : http://localhost/test.php?link1=true And the Output of this url is This is Link 1 Now if I change this url to : http://localhost/test.php?link3=true&link2=true&link1=true And the Output what I get is This Is Link 1This Is Link 2This Is Link 3 Now this is ok here, but it's very annoying if someone types this and see's forms one below the other, any way I can stop this tampering?

• Cached data accessed by reference?

  - by arthurdent510

  I am running into an odd problem, and this is the only thing I can think of. I'm storing a list in cache, and I am randomly losing items from my list as users use the site. I have a class that is called that either goes to cache and returns the list from there, or if the cache is over a certain time frame old, it goes to the database and refreshes the cache. So when I pull the data from cache, this is what it looks like.... results = (List<Software>)cache["software"]; And then I return results and do some processing, filter for security, and eventually it winds up on the screen. For each Software record, there can be multiple resources attached to it, and based on how the security goes they may see some, all, or none of the records. So in the security check it will remove some of those resources from the software record. So my question is.... when I return my results list, is it a reference directly to the cache object? So when I remove a resource from the software object, it is really removing from cache as well? If that is the case, is there any way to not return it as a reference? Thanks!

• Online job-searching is tedious. Help me automate it.

  - by ehsanul

  Many job sites have broken searches that don't let you narrow down jobs by experience level. Even when they do, it's usually wrong. This requires you to wade through hundreds of postings that you can't apply for before finding a relevant one, quite tedious. Since I'd rather focus on writing cover letters etc., I want to write a program to look through a large number of postings, and save the URLs of just those jobs that don't require years of experience. I don't require help writing the scraper to get the html bodies of possibly relevant job posts. The issue is accurately detecting the level of experience required for the job. This should not be too difficult as job posts are usually very explicit about this ("must have 5 years experience in..."), but there may be some issues with overly simple solutions. In my case, I'm looking for entry-level positions. Often they don't say "entry-level", but inclusion of the words probably means the job should be saved. Next, I can safely exclude a job the says it requires "5 years" of experience in whatever, so a regex like /\d\syears/ seems reasonable to exclude jobs. But then, I realized some jobs say they'll take 0-2 years of experience, matches the exclusion regex but is clearly a job I want to take a look at. Hmmm, I can handle that with another regex. But some say "less than 2 years" or "fewer than 2 years". Can handle that too, but it makes me wonder what other patterns I'm not thinking of, and possibly excluding many jobs. That's what brings me here, to find a better way to do this than regexes, if there is one. I'd like to minimize the false negative rate and save all the jobs that seem like they might not require many years of experience. Does excluding anything that matches /[3-9]\syears|1\d\syears/ seem reasonable? Or is there a better way? Training a bayesian filter maybe?

• Speed comparison - Template specialization vs. Virtual Function vs. If-Statement

  - by Person

  Just to get it out of the way... Premature optimization is the root of all evil Make use of OOP etc. I understand. Just looking for some advice regarding the speed of certain operations that I can store in my grey matter for future reference. Say you have an Animation class. An animation can be looped (plays over and over) or not looped (plays once), it may have unique frame times or not, etc. Let's say there are 3 of these "either or" attributes. Note that any method of the Animation class will at most check for one of these (i.e. this isn't a case of a giant branch of if-elseif). Here are some options. 1) Give it boolean members for the attributes given above, and use an if statement to check against them when playing the animation to perform the appropriate action. Problem: Conditional checked every single time the animation is played. 2) Make a base animation class, and derive other animations classes such as LoopedAnimation and AnimationUniqueFrames, etc. Problem: Vtable check upon every call to play the animation given that you have something like a vector<Animation>. Also, making a separate class for all of the possible combinations seems code bloaty. 3) Use template specialization, and specialize those functions that depend on those attributes. Like template<bool looped, bool uniqueFrameTimes> class Animation. Problem: The problem with this is that you couldn't just have a vector<Animation> for something's animations. Could also be bloaty. I'm wondering what kind of speed each of these options offer? I'm particularly interested in the 1st and 2nd option because the 3rd doesn't allow one to iterate through a general container of Animations. In short, what is faster - a vtable fetch or a conditional?

• Check a list of packages to install with apt-get

  - by Joel

  I am writing a post-install script for Ubuntu in Perl (same script as seen here). One of the steps is to install a list of packages. The problem is that if apt-get install fails in some of many different ways for any one of the packages the script dies badly. I would like to prevent that from happening. This happens because of the ways that apt-get install fails for packages that it doesn't like. For example when I try to install a nonsense word (i.e. typed in the wrong package name) $ sudo apt-get install oblihbyvl Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package oblihbyvl but if instead the package name has been obsoleted (installing handbrake from ppa) $ sudo apt-get install handbrake Reading package lists... Done Building dependency tree Reading state information... Done Package handbrake is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'handbrake' has no installation candidate $ apt-cache search handbrake handbrake-cli - versatile DVD ripper and video transcoder - command line handbrake-gtk - versatile DVD ripper and video transcoder - GTK GUI I have tried parsing the results of apt-cache and apt-get -s install to try to catch all possibilities before doing the install, but I seem to keep finding new ways to allow failures to continue to the actual install system command. My question is, is there some facility either in Perl (e.g. a module, though I would like to avoid installing modules if possible as this is supposed to be the first thing run after a new install of Ubuntu) or apt-* or dpkg that would let me be sure that the packages are all available to be installed before installing and if not fail gracefully in some way that lets the user decide what to do?

• EFv1 mapping 1 to many Relationship to POCOs

  - by Scott

  I'm trying to work through a problem where I'm mapping EF Entities to POCO which serve as DTO. I have two tables within my database, say Products and Categories. A Product belongs to one category and one category may contain many Products. My EF entities are named efProduct and efCategory. Within each entity there is the proper Navigation Property between efProduct and efCategory. My Poco objects are simple public class Product { public string Name { get; set; } public int ID { get; set; } public double Price { get; set; } public Category ProductType { get; set; } } public class Category { public int ID { get; set; } public string Name { get; set; } public List<Product> products { get; set; } } To get a list of products I am able to do something like public IQueryable<Product> GetProducts() { return from p in ctx.Products select new Product { ID = p.ID, Name = p.Name, Price = p.Price ProductType = p.Category }; } However there is a type mismatch error because p.Category is of type efCategory. How can I resolve this? That is, how can I convert p.Category to type Category? I know in .NET EF has added support for POCO, but I'm forced to use .NET 3.5 SP1.

  I have 2 sets of depth point measurements, for example: > a depth value 1 2 2 2 4 3 3 6 4 4 8 5 5 16 40 6 18 45 7 20 58 > b depth value 1 10 10 2 12 20 3 14 35 I want to show both groups in one figure plotted with depth and with different symbols as you can see here plot(a$value, a$depth, type='b', col='green', pch=15) points(b$value, b$depth, type='b', col='red', pch=14) The plot seems okay, but the annoying part is that the green symbols are all connected (though I want connected lines also). I want connection only when one group has a continued data points at 2 m interval i.e. the symbols should be connected with a line from 2 to 8 m (green) and then group B symbols should be connected from 10-14 m (red) and again group A symbols should be connected (green), which means I do NOT want to see the connection between 8 m sample with the 16 m for group A. An easy solution may be dividing the group A into two parts (say, A-shallow and A-deep) and then plotting A-shallow, B, and A-deep separately. But this is completely impractical because I have thousands of data points with hundreds of groups i.e. I have to produce many depth profiles. Therefore, there has to be a way to program so that dots are NOT connected beyond a prescribed frequency/depth interval (e.g. 2 m in this case) for a particular group of samples. Any idea?

• jQuery Suspected Naming Convention Problem

  - by donfigga

  Hi all, I'm having a problem with this jQuery function, the portion of the function that renames the id, class and name of the dropdown only works for the first dropdown, subsequent ones do not work, any ideas? I suspect it may have something to do with naming convention as in cat.parent_id but it is required for asp.net mvc model binding. $(document).ready(function () { $("table select").live("change", function () { var id = $(this).attr('id'); if ($(this).attr('classname') != "selected") { var rowIndex = $(this).closest('tr').prevAll().length; $.getJSON("/Category/GetSubCategories/" + $(this).val(), function (data) { if (data.length > 0) { //problematic portion $("#" + id).attr('classname', 'selected'); $("#" + id).attr('name', 'sel' + rowIndex); $("#" + id).attr('id', 'sel' + rowIndex); var position = ($('table').get(0)); var tr = position.insertRow(rowIndex + 1); var td1 = tr.insertCell(-1); var td2 = tr.insertCell(-1); td1.appendChild(document.createTextNode('SubCategory')); var sel = document.createElement("select"); sel.name = 'parent_id'; sel.id = 'parent_id'; sel.setAttribute('class', 'unselected'); td2.appendChild(sel); $('#parent_id').append($("<option></option>").attr("value", "-1").text("-please select item-")); $.each(data, function (GetSubCatergories, Category) { $('#parent_id').append($("<option></option>"). attr("value", Category.category_id). text(Category.name)); }); sel.name = 'cat.parent_id'; sel.id = 'cat.parent_id'; } }); } }); });

• Where can I view rountrip information in my ASP.NET application?

  - by ajax81

  Hi All, I'm playing around with storing application settings in my database, but I think I may have created a situation where superfluous roundtrips are being made. Is there an easy way to view roundtrips made to an MS Access (I know, I know) backend? I guess while I'm here, I should ask for advice on the best way to handle this project. I'm building an app that generates links based on file names (files are numbered ints, 0-5000). The files are stored on network shares, arranged by name, and the paths change frequently as files are bulk transfered to create space, etc. Example: Files 1000 - 2000 go to /path/1000s Files 2001 - 3000 go to /path/2000s Files 3001 - 4000 go to /path/3000s etc I'm sure by now you can see where I'm going with this. Ultimately, I'm trying to avoid making a roundtrip to get the paths for every single file as they are displayed in a gridview. I'm open to the notion that I've gone about this all wrong and that my idea might be rubbish. I've toyed around with the notion of just creating a flat file, but if I do that, do I still run into the problem of having that file opened and closed for every file displayed in a gridview?

• What makes you trust that a piece of open source software is not malicious?

  - by Daniel DiPaolo

  We developers are in a unique position when it comes to the ability to not only be skeptical about the capabilities provided by open source software, but to actively analyze the code since it is freely available. In fact, one may even argue that open source software developers have a social responsibility to do so to contribute to the community. But at what point do you as a developer say, "I better take a look at what this is doing before I trust using it" for any given thing? Is it a matter of trusting code with your personal information? Does it depend on the source you're getting it from? What spurred this question on was a post on Hacker News to a javascript bookmarklet that supposedly tells you how "exposed" your information on Facebook is as well as recommending some fixes. I thought for a second "I'd rather not start blindly running this code over all my (fairly locked down) Facebook information so let me check it out". The bookmarklet is simple enough, but it calls another javascript function which at the time (but not anymore) was highly compressed and undecipherable. That's when I said "nope, not gonna do it". So even though I could have verified the original uncompressed javascript from the Github site and even saved a local copy to verify and then run without hitting their server, I wasn't going to. It's several thousand lines and I'm not a total javascript guru to begin with. Yet, folks are using it anyway. Even (supposedly) bright developers. What makes them trust the script? Did they all scrutinize it line by line? Do they know the guy personally and trust him not to do anything bad? Do they just take his word? What makes you trust that a piece of open source software is not malicious?
