• 10 lines of code per day is the global average!? -- true?

  - by Earlz

  Ok so last year I participated in a high school curriculum contest thing at a college(I currently attend this college). I actually got 1st in it but was still a bit angry I didn't get every single one right. The most baffling of questions on there was How many lines of code does the average programmer write per day? A. 5 B. 10 C. 25 D. 30 Aside from being a subjective question which depended on language and everything else I was more baffled at what they had as the correct answer. 10. Even on my bad days at my job I touch more than 10 lines of code(either adding, modifying, or deleting) per day. And when I took this test I had only programmed as a hobby where it was common for me to write a few hundred lines for one of my new projects per day. Where are they getting this random number of ten!? Is this published somewhere? A quick googling found me nothing.

• Optimizations employed by ORM's

  - by Kartoch

  I'm teaching JEE, especially JPA, Spring and Spring MVC. As I have not so much experience in large projects, it is difficult to know what to present to students about optimisation of ORM. At the present time, I present some classic optimisation tricks: prepared statements (most of ORM implicitely uses it by default) first and second-level caches "write first, optimize later" it is possible to switch off ORM and send SQL commands directly to the database for very frequent, specialized and costly requests Is there any other point the community see about other way to optimize ORM ? I'm especially interested by DAO patterns...

• MySQL Interview Questions

  - by Campbell

  Hi, I've been asked to screen some candidates for a MySQL DBA / Developer position for a role that requires an enterprise level skill set. I myself am a SQL Server person so I know what I would be looking for from that point of view with regards to scalability / design etc but is there anything specific I should be asking with regards to MySQL? I would ideally like to ask them about enterprise level features of MySQL that they would typically only use when working on a big database. Need to separate out the enterprise developers from the home / small website kind of guys. Thanks.

• Facebook graph API - OAuth Token

  - by Simon R

  I'm trying to retrieve data using the new graph API, however the token I'm retriving from OAuth doesn't appear to be working. The call I'm making is as follows; $token = file_get_contents('https://graph.facebook.com/oauth/access_token?type=client_cred&client_id=<app_id>&client_secret=<app secret>'); This returns a token with a string length of 41. To give you an example of what is returned I have provided below a sample (converted all numbers to 0, all capital letters to 'A' and small case letters to 'a' access_token=000000000000|AaaAaaAaaAAaAaaaaAaaAa0aaAA. I take this access token and attach it to the call request for data, it doesn't appear to be the correct token as it returns nothing. I make the data call as follows; file_get_contents('https://graph.facebook.com/<my_page's_id>/statuses?access_token=000000000000|AaaAaaAaaAAaAaaaaAaaAa0aaAA.') When I manually retrieve this page directly through the browser I get an 500/Internal Server Error Message. Any assistance would be grately appreciated.

• LiNQ to Entities, Include less

  - by Freddy

  Hi, If you are making a LinQ to entities expression for ClassA where A has a relation to ClassB like this: var temp = from p in myEntities.ClassA.Include("ClassB") where ... select p; You will get a set of ClassA:s with the reference to ClassB loaded. The thing in my case is that I dont really need to load ALL the ClassB-references, just a few of them. But I dont want to loop through the list of ClassA:s and load them individually, i want my database operations to be fewer and bigger instead of reading small chunks here and there. Is it possible to put some kind of restrictions on which references to include or do you have to accept this all or nothing style?

• Sourcecode for Paymentroll example in Robert C. Martin book

  - by bitbonk

  Throughout the book "Agile Principles, Patterns, and Practices in C#" by Robert C. Martin a small Paymentroll application is build. While most of the source code is printed in place, some classes are missing and some are incomplete. The book says on the firest page: The book includes many source code examples that are also available for download from the authors' Web site. Unfortunately this seems to be a lie. Unless either this is not the author's website (the book forgets to mention the authors website adress) or I am blind. Does anyone have the comlete source code for that book preferably in form of a Visual Studio project or knows where I can find it.

• How to create a new LaTeX command that behaves something like \verb?

  - by NawaMan

  I have been using LaTeX from sometime now, but have never actually gotten my hands dirty declaring a new command, as I try to avoid that. However, I need to add monospace text often in my document and I use \verb for it which is fine, except that the verb font size is bigger than the normal text font. So I need to change the font size and undo done like \small{}\verb#My monospace code#\normalsize{}. This is not very convenient and mistake-prone. Is there a better way to do this? Can I define a new command for this? How?

• Is it possible to connect iPhones through NAT traversal techniques over 3G for peer 2 peer gaming

  - by Dougnukem

  Is it possible to connect an iPhone to another iPhone or any other network client talking that game's protocol. I was thinking that I could use the same NAT Traversal technique used in the XBox 360 to host games on users XBox's through Firewalls. For NAT traversal to work effectively I'd have to have a central server that would allow clients to "broadcast" that they were hosting so that another client could initiate the NAT connection. In the link provided this is called relaying. Is there any inherent limitation of the US AT&T 3G network that will block the NAT traversal techniques (would you be limited to wifi firewall NAT traversal)? NAT Traversal Projects: - PJSIP - providing NAT traversal functionalities by using standard based protocols such as STUN, TURN, and ICE. - Freecast using Apache MINA Java network library for NAT Traversal

• Very slow startup of ASP.NET applications

  - by Conrad

  I have an ASP.NET applications with quite small number of pages. The problem I see is that the startup time is quite slow. As far as I can tell, most of the time is spent in JIT. Pre-compiling the applications seem not very helpful in reducing the #methods JIT as reported thru PerfMon. Does anybody know what I can do to reduce the startup time further? Is it true that there is no way to pre-jit an ASP.NET application using NGEN?

• jqgrid scrollable dialog

  - by gurun8

  I have a jqGrid that has add/edit dialogs with a form that's longer than the dialog height but the dialog won't scroll. I've tried to add an overflow: auto style to the dialog but no effect: $("div.ui-jqdialog-content").css("overflow", "auto"); Although, if I change auto to scroll, I at least see a scrollbar but still no scrolling: $("div.ui-jqdialog-content").css("overflow", "scroll"); This at least gives me a small glimmer of hope that I'm on the right track. There doesn't seem to be any direction from the API documentation to support scrolling: http://www.trirand.com/jqgridwiki/doku.php?id=wiki:form_editing Does anyone know how to add a working scrollbar to the jqModal dialog window used by jqGrid?

• ExtAsp or Coolite - ASP.NET wrappers around ExtJs

  - by Jon

  Hi, We are a small Microsoft shop looking into ExtJs and like the rapid building of complex and structured UIs that can be achieved with the toolkit. However we have been experimenting with ExtAsp.NET (CodePlex) which is an opensource layer of ASP.NET code which wraps around the ExtJs framework. We have also noticed the Coolite framework which looks good too and does the same thing. We have 2 options, either we purchase the ExtJs license which will be required if we use ExtAsp, or we purchase the Coolite kit which includes the ExtJs license. It looks like Coolite is actually it little cheaper than the ExtJs for some reason?? However, is it a little more risky as regards upgrade path if the Coolite framework becomes unsupported, whereas ExtAsp as an open source solution will have community backing? Just looking to make the right step.

• Open Financial Exchange (OFX) Banking API

  - by Gabriel Susai

  Hi, First of all I apologize if this question is asked before. I am planning to develop a small application which displays my bank account details(like Mint.com) where I can customize the display of my own. I want to know how and where to start. Where these OFX API's are available? Are they free or we need to pay and get access to those API? What is data format ( xml, xml/atom, json) ? Any article or document to understand this requirement and start developing? Any open source software where I can download the code and customize it? FYI : I am working on C#.Net. Any help would be appreciated. Edit : Mark : Thanks for you info. If I want to develop a application like Mint.com what are the other companies provide API's other than Yoodlee? Also any idea on the pricing? Thanks Gabriel Susai

• Reputable TabletPC vendors

  - by SnOrfus

  I'm developing software for tablet pcs and so far I've used some lenovo's (x41), some toshiba's (portege m200) and some gateways (M275). Granted: the machines we've gotten have predominantly been refurbs, but they're failing 80-90% of the time. Part of the reason that they're failing is users inevitably dropping them, so I'm looking at potentially some rugged tablet pcs. The problem that I'm running into is that Current tablet pcs are high spec (much higher than I'm looking for at least) The rugged tablet manufacturer space seems to be filled with lots of small companies that I don't trust yet. I'm looking for tablet PCs (keyboard or no) that can support: XP tpc (optional win 7) single core 1.5-2ghz 1gb ram wifi optional gsm optional gps very optional vehicle docking solutions The budget I've got is tight (but slightly flexible - So are there any reputable tablet pc vendors out there that can do this.

• Converting EBNF to BNF

  - by Vivin Paliath

  It's been a few years since my computer-language class and so I've forgotten the finer points of BNF's and EBNF's and I don't have a textbook next to me. Specifically, I've forgotten how to convert an EBNF into BNF. From what little I remember, I know that one of the main points is to convert { term } into <term> | <many-terms>. But I don't remember the other rules. I've tried to look this up online but I can only find links to either homework questions, or a small comment about converting terms with curly braces. I can't find an exhaustive list of rules that define the translation.

• What is the difference between DVCS systems?

  - by Stephen

  What is the difference between DVCS systems? Seriously, wikipedia doesn't cover it well, and I read an article on HN recently comparing git and bzr in some detail, but the author admitted knowing little about mercurial, and the other options didn't get mentioned. (I'm happily using fossil on small win/mac/Linux projects) Please restrict answers to the DVCS aspects of the tool, e.g. The basic unit of vc in hit is the repository- in bazaar it is the branch(http://unspecified.wordpress.com/2010/03/26/why-git-aint-better-than-x/). bugtrackers and wikis are nice, but I'm really interested in the tools themselves, rather than any extras. Unfortunately SO demands a single 'right answer', so I'm making the question community wiki in the hope that users will contribute their knowledge.

• iPhone: Failed to launch simulated application: Unknown error.

  - by Schubert

  This is a new iPhone project, only 1 target (different from this question) On build we get: Failed to launch simulated application: Unknown error. The google again gives us nothing, lots of people have encountered this and there are lots of crazy ideas to try "oh clean the build", "clear the cache", "twiddle this flag" and none of them work and work consistently. We can reproduce this on two different machines with SDK 2.2.1 and 3.0 beta. Not the install on the machines since other iphone projects work just fine so we believe it has something to do with the config of this particular project but after combing through the config twice we can't spot the problem. Vanna, I'd like to buy a clue for $200 please. Tried: XCode menu-Clear cache Tried: clean all targets Tried: rm -rf ~/Library/Application\ Support/iPhone\ Simulator

• Avoiding .NET versioning hell

  - by moogs

  So sometimes (oftentimes!) you want to target a specific .NET version (say 3.0), but then due to some .NET service packs you get into problems like: Dispatcher.BeginInvoke(Delegate, Object[]) <-- this was added in 3.0 SP2 (3.0.30618 ) System.Threading.WaitHandle.WaitOne(Int32) <-- this was added in 3.5 SP1, 3.0 SP2, 2.0 SP2 Now, these are detected by the JIT compiler, so building against .NET 3.0 in Visual Studio won't guarante it will run on .NET 3.0 only systems. Short of confirming each and every function you use, or limiting your development environment to .NET 3.0 (which sucks since you have to develop for other projects too) what's the best way to avoid against using extensions? Thanks!

• Setting freemarker template from classpath

  - by wuntee

  I have a web application that I need to manually obtain a Freemarker template - the template is obtained via a class in a library project, but the actual tpl file is contained in the web application classpath. So, there are 2 projects, one 'taac-backend-api' and another 'taac-web'; taac-backend-api has the code to grab the template, and process it, but taac-web is where the template is stores (specifically in: WEB-INF/classes/email/vendor.tpl) - I have tried everything from using springs classpath resource to using Freemarkers setClassForTemplateLoading method. I assume this would work: freemarkerConfiguration = new Configuration(); freemarkerConfiguration.setClassForTemplateLoading(this.getClass(), ""); Template freemarkerTemplate = freemarkerConfiguration.getTemplate("/email/vendor.tpl"); yet, I always get a FileNotFoundException. Can someone explain the best way to obtain a template from the classpath? Thanks.

• Setting my PictureBox to transparent background color doesn't really make it transparent. Bug?

  - by Sergio Tapia

  Here's what I have in VERY simple easy to grasp terms. My form background is Blue. I created a gradient image from white to the Blue from the form background. This is to give the form a nice gradient look. I added a picturebox to my Form and set this image as the Image. I added a picturebox with a Logo on top of the gradient Picturebox, but it's 'grabbing' the Form background color and not respecting the transparent background image I wanted it to grab. So: Blue Form - Huge pictureBox with gradient - Small picturebox thats supposed to respect the gradient. Help please!
