• Is type safety worth the trade-offs?

  - by Prof Plum

  I began coding in in Python primarily where there is no type safety, then moved to C# and Java where there is. I found that I could work a bit more quickly and with less headaches in Python, but then again, my C# and Java apps are at much higher level of complexity so I have never given Python a true stress test I suppose. The Java and C# camps make it sound like without the type safety in place, most people would be running into all sorts of horrible bugs left an right and it would be more trouble than its worth. This is not a language comparison, so please do not address issues like compiled vs interpreted. Is type safety worth the hit to speed of development and flexibilty? WHY? to the people who wanted an example of the opinion that dynamic typing is faster: "Use a dynamically typed language during development. It gives you faster feedback, turn-around time, and development speed." - http://blog.jayway.com/2010/04/14/static-typing-is-the-root-of-all-evil/

• From Imperative to Functional Programming

  - by user66569

  As an Electronic Engineer, my programming experience started with Assembly and continue with PL/M, C, C++, Delphi, Java, C# among others (imperative programming is in my blood). I'm interested in add to my previous knowledge, skills about functional programming, but all I've seen until now seems very obfuscated and esoteric. Can you please answer me these questions? 1) What is the mainstream functional programming language today (I don't want to get lost myself studying a plethora of FP languages, just because language X has the feature Y)? 2) What was the first FP language (the Fortran of functional programming if you want)? 3) Finally, when talking about pure vs. non pure FP what are the mainstream languages of each category? Thank you in advance

• OSB, Service Callouts and OQL - Part 1

  - by Sabha

  Oracle Fusion Middleware customers use Oracle Service Bus (OSB) for virtualizing Service endpoints and implementing stateless service orchestrations. Behind the performance and speed of OSB, there are a couple of key design implementations that can affect application performance and behavior under heavy load. One of the heavily used feature in OSB is the Service Callout pipeline action for message enrichment and invoking multiple services as part of one single orchestration. Overuse of this feature, without understanding its internal implementation, can lead to serious problems. This post will delve into OSB internals, the problem associated with usage of Service Callout under high loads, diagnosing it via thread dump and heap dump analysis using tools like ThreadLogic and OQL (Object Query Language) and resolving it. The first section in the series will mainly cover the threading model used internally by OSB for implementing Route Vs. Service Callouts. Please refer to the blog post for more details.

• Good resources for learning about graphics hardware

  - by Ken

  I'm looking for some good learning resources for graphics hardware (and associated low level software). Basically I want to learn more about what goes on underneath the opengl/direcx API layers in terms of how things are implemented. I familiar with what happens in principle during the various stages of the rendering pipeline (viewing, projection, clipping, rasterization etc). My goal is to be able to make better and more informed decisions about tradeoffs and potential optimisations when graphics/shader programming with respect to the following kinds of issues; batching view culling occlusions draw order avoiding state changes triangles vs pointsprites texture sampling etc Basically whatever the graphics programmer needs to know about modern graphics hardware in order to become more effective. I'm not really looking for specific optimisation techniques, rather I need more general knowledge so that I will naturally write more efficient code.

• The case against INFORMATION_SCHEMA views

  - by AaronBertrand

  In SQL Server 2000, INFORMATION_SCHEMA was the way I derived all of my metadata information - table names, procedure names, column names and data types, relationships... the list goes on and on. I used the system tables like sysindexes from time to time, but I tried to stay away from them when I could. In SQL Server 2005, this all changed with the introduction of catalog views. For one thing, they're a lot easier to type. sys.tables vs. INFORMATION_SCHEMA.TABLES? Come on; no contest there - even...(read more)

• Choosing the right version control system for .NET projects [closed]

  - by madxpol

  I'm getting ready for my first "bigger" .NET project (ASP.NET MVC 3/4) on which I'm going to lead another 2 programmers and right now I'm choosing the right version control system for the job (plus I'm gonna use it for my future development too). My problem is that I did't use any version control system before, so I would like it to have as fast learning curve and intuitive merging as possible. So far I quickly looked at VisualSVN (I like the Visual Studio integration in it), but I'm reading everywhere how Git is awesome and dunno which one to choose (not limited to these two).. Maybe I'm ovethinking this but I like when everything goes smoothly:) I'd like to hear some opinions from people who used multiple version control systems (preferably on VS projects) what do you think is the less complicated and effective version control system for such a use (one to 5 man projects)?

• What is Perl's relation to hackers? [closed]

  - by K.Steff

  I know Perl is a language revered by many hackers (as in hacker vs cracker) and respected by many good programmers for its expressiveness. I also realize it is useful to know and it's very handy at generalizing common Unix tasks (Unix here includes Linux and Cygwin). I also know that being a good hacker probably means you're a good programmer in general (references on this one are sparse around the web, but about everything Paul Graham has ever written seems approving of this statement to me). So my question is whether there is a reason that attracts hackers to Perl in particular? Will learing Perl improve my general programming, problem-solving and hacking skills if done properly? Does it present unique tools that are more useful to a hacker?

• Salting a public hash

  - by Sathvik

  Does it make any sense at all to salt a hash which might be available publicly? It doesn't really make sense to me, but does anyone actually do that? UPDATE - Some more info: An acquaintance of mine has a common salted-hash function which he uses throughout his code. So I was wondering if it made any sense at-all, to do so. Here's the function he used: hashlib.sha256(string+SALT).hexdigest() Update2: Sorry if it wasn't clear. By available publicly I meant, that it is rendered in the HTML of the project (for linking, etc) & can thus be easily read by a third party. The project is a python based web-app which involves user-created pages which are tracked using their hashes like myproject.com/hash so thus revealing the hash publicly. So my question is, whether in any circumstances would any sane programmer salt such a hash? Question: Using hashlib.sha256(string+SALT).hexdigest() vs hashlib.sha256(string).hexdigest() , when the hash isn't a secret.

• How do I create and link to a database in ASP.NET (Razor) with Visual studio 2013?

  - by Blake

  We have a simple web app, part of which allows users to create accounts and then, hopefully soon, to write blog posts. The user log in system is working great, it utilizes the given .sdf database created when a new project is created. We would like to expand it now to allow for blog data (the title, body of the blog, image posts perhaps, etc). However, I'm unsure of how to add another table to the user database for this purpose - or if that would even be best since it has sensitive information in it. I've been reading blog post after blog post and still can't find anything current on this. All of the articles are for MVC projects or older versions of VS. If someone could point me in the right direction it would be greatly appreciated!

• RPG Item processing

  - by f00b4r

  I started working on an item system for my (first) game, and I'm having a problem conceptualizing how it should work. Since Items can produce a bunch of potentially non-standard actions (revive a character vs increasing some stat) or have use restrictions (can only revive if a character is dead). For obvious reasons, I don't want to create a new Item class for every item type. What is the best way to handle this? Should I make a handful of item types (field modifiers, status modifiers, )? Is it normal to script item usage? Could (should?) this be combined with the above mentioned solution (have a couple of different sub item types, make special case items usage scripted)? Thanks.

• Material usage, one per model or per object?

  - by WSkid

  Is it better (memory, time (of developer), space) to use single model that is unwrapped and uses a single material or to break a model down into appropriate bits, each with their own smaller texture/material? Or does it depend on the target platform as to what is acceptable - ie PC vs tablet? An example: Say you have a typical house with a tiled roof. Model it, make sure everything is attached, unwrap the walls/roof so in your UV template the walls and roof would be in one texture file, side-by-side in say a 512x512 file. Model the roof/walls as separate objects, unwrap them individually and have two UV templates. You could then have a 256x256 file for each one.

• PEX - are you licenced for it?

  - by TATWORTH

  There is an interesting artcile about PEX at http://blogs.msdn.com/b/ukmsdn/archive/2011/02/22/featured-article-pex-and-visual-studio.aspx PEX can be downloaded from http://research.microsoft.com/en-us/projects/pex/downloads.aspx The licence conditions are: "Pex and Moles are Power Tools available for commercial use for MSDN subscribers. Moles is also available separately for commercial use without requiring an MSDN subscription. Pex and Moles are also available for academic and non-commercial use." I note with interest that it is now available to MSDN subscribers. If I recall correctly it used to be only available to VS Team versions.

• What is a *slightly* less extreme equivalent to being "fluent" in a language?

  - by Mehrdad

  tl;dr: What is a less extreme (but still noticeable) alternative to the word "fluent", when saying e.g. "I am fluent in C++/Python/whatever?" I think I can call myself "fluent" in C#, because I know the language and runtime very well, and I'm very familiar with the .NET framework's APIs and classes, etc. I would like to claim the same thing for Python and C++. But while I can program in Python (I did so for an entire summer, making a website with Django), for example, I would not call myself fluent because my code isn't always "Pythonic" (e.g. using map/filter vs. list comprehensions), and I'm not too intimate with some aspects of the language and standard library yet (e.g. the introspection API, etc.). Is there a word or phrase I can use on e.g. a resume to describe what I know? I can think of "very familiar with", but is there a better word/phrase I can use?

• unable to access Internet by wireless but can by cable

  - by Jeff King

  i'M GOING MAD! UNtil last friday I had been successfully using wifi with the supplier as VIRGIN through their Motorola SB 4200 cable Modem and the wireless router being the Linksys WRT 54G router. Supported were three lap tops and an EPSON 510W printer and this had been running with no issue for about 3 years. Back to last friday, we started suffering significant delays and then the network collapsed with no wireless access. I was able to connect a single laptop direct to the cable modem and internet access was restored to just that one device. I thought that the problem was the router so I tried a backup D-Link device with no success. I have subsequently bought another cable modem AND a netgear router plus addidtional ethernet cables but with no success. The best that happens is that the signal appears good but I cannot get access to the internet. A yellow question mark appears on the 'gradient' icon. Each laptop and router works elsewhere so I'm stumped. Mind you I am a real novice so I'm not surprised. Please can anyone tell me what I'm doing wrong?

• Avatar creation / dressing feature

  - by milesmeow

  What is the effort required to use a game engine such as Unreal or Unity, etc. and create an avatar customization features...complete with clothes. The user should be able to customize the body features and the clothes need to then fit onto the customized body. What is needed? Can you create one set of 3D models for clothes and somehow programatically have the clothes adapt to the body shape? I.e. The same shirt model will be able to fit on a skinny person vs. someone with a big beer belly. How difficult is this? What are the steps needed to implement this avatar creation/dressing feature. I'm basically talking about something like in Rockband 3.

• Distributing a very simple application

  - by vanna

  I have a very simple working console application written in C++ linked with a light static library. It is just for testing purposes. Now that the coding part is done, I would like to know the process of actually distributing the program. I wrote a very basic CMakeLists.txt that create makefiles or VS projects to build the sources. I also have a program that calls the static library in order to make some google tests. To me, the distribution of this application goes like this : to developpers : the src directory with the CMakeLists.txt file (multi-platform distribution) with a README.txt and an INSTALL.txt to users : the executable and a README.txt on my git repo : everything mentionned above plus the sources for testing and the gtest external lib A this point : considering the complexity of my application, am I doing it right ? Is there any reference that would formalize this distribution process so I can get better and go further ? Say I would like to add dynamic libraries that can be updated, external libraries like boost : how should I package this to distribute it in a professionnal way ?

• How can I fix intermittent iSight camera functionality on a Macbook Pro 5,2?

  - by Mmmm

  I have a Macbook Pro 5,2 laptop dual booting OSX and Ubuntu. The built-in iSight video camera works only sporadically. By that I mean that sometimes if I boot and try to use the camera it does not work (most of the time) but other times it does. I don't have good repeatable data regarding when it does vs. when it doesn't other than to say that it always seems to work right after I upgrade to a new Linux kernel with the Update Manager and reboot, but then eventually stops working again until I upgrade the kernel again. That is hard to test repeatably, so it's hard to know for sure that that is the case. This has happened consistently with every version of Ubuntu from 10.10 through 11.10. I can get around this by booting into the OS/X partition, since all of the hardware obviously works perfectly on that side of things, but it would be great if I could remain in Ubuntu and do the same thing. Thanks in advance for any inSights.

• How many CISC instructions do compilers use?

  - by Euphoric

  CISC processors have sometimes huge instruction sets. This makes assembly programming somehow easier. But it reduces overall effectivness of the whole chip. But how many of those instructions are used by modern compilers? I'm especialy interested in relation of CISC vs. RISC where in CISC, compiler can use specialised instructions, that might increase effectivness. But do compilers use those instructions? If yes, then how many of them are used?

• Why is REMOTE_ADDR only sometimes available as an Apache environment variable?

  - by Xiong Chiamiov

  To avoid having to parse X-Forwarded-For in Varnish, I'm trying to just set a header on the SSL terminator (currently Apache) that stores the direct client IP in a header. On our development machine, this works: RequestHeader set X-Foo %{REMOTE_ADDR}e However, in staging it doesn't. Specifically, the header is empty, as illustrated by both varnishlog: 13 TxHeader b X-Foo: (null) (On the development machine, this shows the IP address as expected.) Similarly, logging REMOTE_ADDR shows that it only appears to be populated on the dev machine: # Config LogFormat "%{X-Forwarded-For}i %{REMOTE_ADDR}e" combined CustomLog "/var/log/httpd/access_log" combined # Log file, staging <my ip> - # Log file, development <my ip> <my ip> Since the dev machine is, well, a dev machine, it is different in a number of ways; however, I can't track down which difference is causing this. The versions of Apache are the same (2.2.22), and I don't see anything relevant in any of the standard config files or /etc/sysconfig/httpd. And the rest of the system is reasonably similar, since they're built off the same CentOS 5 base image. I can't even tell from the Apache documentation whether REMOTE_ADDR is expected to exist or not as an environment variable, but it clearly works on one machine, whether by fluke or design, and the inconsistency is driving me mad.

• Security settings for this service require 'Basic' Authentication

  - by Jake Rutherford

  Had an issue calling WCF service today. The following exception was being thrown when service was called:WebHost failed to process a request. Sender Information: System.ServiceModel.ServiceHostingEnvironment+HostingManager/35320229 Exception: System.ServiceModel.ServiceActivationException: The service '/InteliChartVendorCommunication/VendorService.svc' cannot be activated due to an exception during compilation.  The exception message is: Security settings for this service require 'Basic' Authentication but it is not enabled for the IIS application that hosts this service..Ensured Basic authentication was indeed enabled in IIS before getting stumped on what actual issue could be. Turns out it was CustomErrors setting. Value was set to "off" vs "Off". Would have expected different exception from .NET (i.e. web.config parse exception) but it works now either way.

• Should I leave href empty when implementing click events via jQuery?

  - by dreza

  Is it preferable to have # in a link's href attribute when I am implementing the click event via jQuery, or is it ok to leave href empty? i.e. <a id="myLink" href="#" /> vs <a id="myLink" href="" /> When I'm doing $("#myLink").on('click', function() { // do ajaxy stuff }); Although I understand the click event could be on a span or other such element I'm interested in this case for particular best practices when using an a tag.

• When and How is an image cached for an ASPX with ContentType = image/jpeg ?

  - by Aamir Hasan

   In asp.net you can cache your page. You can vary the output cache by the followingThe query string in an initial request (HTTP GET).Control values passed on postback (HTTP POST values).The HTTP headers passed with a request.The major version number of the browser making the request.      A custom string in the page. In that case, you create custom code in the Global.asax file to specify the page's caching behavior.Link: http://msdn2.microsoft.com/en-us/library/xadzbzd6(VS.80).aspxyou can set the output caching for your GetImage.aspx, so that you dont have to requery the database every image request ,but you must use varybyParam , so that you have a cached version for every parameters arrangement:set the output cache for your page like this :At top of ASPX page: <%@ OutputCache Duration="600" VaryByParam="ID,Height,Width" %>VaryByParam  attribute allows you to vary the cached output depending on the query string.Adding this will make your images cached for 600 seconds, so that if the image request within this period ,the cahed version will be returned
