• IIS cache control header settings

  - by a_m0d

  I'm currently working on a website that is accessed over https. We have recently come across a problem where we are unable to view .pdf files or any other type of file that is sent as an attachment (Content-Disposition:attachment). According to Microsoft Knowledge Base this is due to the fact that Cache-Control is set to no-cache. However, we have a requirement that all pages be fully reloaded every time they are visited, so we have disabled caching on all pages (through our ASP code, not through IIS settings). However, I have made a special case of this one page that shows the attachment, and it now returns a header with Cache-Control:private and the expiry set to 1 minute in the future. This works fine when I test it on my local machine, using https. However, when I deploy it to our test server and try it, the response headers still return Cache-Control:no-cache. There is no firewall or anything between me and the server, so IIS itself must be adding these headers and replacing mine. I have no idea why it would do this, and it doesn't really make any sense, but it seems to be the only option at the moment (I haven't yet found any other place in the code that will change the cache headers). Can anyone point me to a possible place where IIS might be setting these header values?

• Your Experience Platform

  - by David Dorf

  Crosstalk once again exceeded my expectations, improving upon last year's conference in terms of venue, knowledge sharing, and entertainment.  Its great to see the Oracle Retail family continues to grow, especially outside the US.  I had a great time talking to retailers, analysts, press, and colleagues from around the world. Because the economy, demographics, technology, etc. are constantly changing, retailers must always be evolving their business to capture the next market.  But it takes guts to change something that appears to be working, and it takes a bit of luck to get the timing right.  To a large extent, innovation is about "guts and luck." To help retailers innovate, Oracle Retail provides all the necessary software to create Your Experience Platform.  There is no "Oracle Experience Platform" as each retailer needs something different to deliver on their brand promise.  We provide the actionable insight, optimized operations, and connected interactions, but its still up to the retailer to make it theirs. One such retailer is Masters, a home improvement retailer in Australia formed through a partnership between Woolworths and Lowes.  Woolworths is an established retailer in Australia, so they are already close to their customers and able to understand their needs.  In Australia 74% of dwellings are detached houses and the population is continues to "move up" into bigger and bigger homes. Masters is using Oracle Retail's software to create their experience platform that will deliver on their brand promise, which includes everyday low prices, wide range of products, smarter self-service, and an inviting store environment.  The Oracle Retail software provides the foundation that allows them to rapidly deliver on this promise -- Masters is engineered for success.

• Hallmarks of a Professional PHP Programmer

  - by Scotty C.

  I'm a 19 year old student who really REALLY enjoys programming, and I'm hoping to glean from your years of experience here. At present, I'm studying PHP every chance I get, and have been for about 3 years, although I've never taken any formal classes. I'd love to some day be a programmer full time, and make a good career of it. My question to you is this: What do you consider to be the hallmarks or traits of a professional programmer? Mainly in the field of PHP, but other, more generalized qualifications are also more than welcome, as I think PHP is more of a hobbyist language and may not be the language of choice in the eyes of potential employers. Please correct me if I'm wrong. Above all, I don't want to wast time on something that isn't worth while. I'm currently feeling pretty confident in my knowledge of PHP as a language, and I know that I could build just about anything I need and have it "work", but I feel sorely lacking in design concepts and code structure. I can even write object oriented code, but in my personal opinion, that isn't worth a hill of beans if it isn't organized well. For this reason, I bought Matt Zandstra's book "PHP Objects, Patterns, and Practice" and have been reading that a little every day. Anyway, I'm starting to digress a little here, so back to the original question. What advice would you give to an aspiring programmer who wants to make an impact in this field? Also, on a side note, I've been working on a project with a friend of mine that would give a fairly good idea of where I'm at coding wise. I'm gonna give a link, I don't want anyone to feel as though I'm pushing or spamming here, so don't click it if you don't want to. But if you are interested on giving some feedback there as well, you can see the code on github. I'm known as The Craw there. https://github.com/PureChat/PureChat--Beta-/tree/

• I don't know C. And why should I learn it?

  - by Stephen

  My first programming language was PHP (gasp). After that I started working with JavaScript. I've recently done work in C#. I've never once looked at low or mid level languages like C. The general consensus in the programming-community-at-large is that "a programmer who hasn't learned something like C, frankly, just can't handle programming concepts like pointers, data types, passing values by reference, etc." I do not agree. I argue that: Because high level languages are easily accessible, more "non-programmers" dive in and make a mess In order to really get anything done in a high level language, one needs to understand the same similar concepts that most proponents of "learn-low-level-first" evangelize about. Some people need to know C; those people have jobs that require them to write low to mid-level code. I'm sure C is awesome, and I'm sure there are a few bad programmers who know C. Why the bias? As a good, honest, hungry programmer, if I had to learn C (for some unforeseen reason), I would learn C. Considering the multitude of languages out there, shouldn't good programmers focus on learning what advances us? Shouldn't we learn what interests us? Should we not utilize our finite time moving forward? Why do some programmers disagree with this? I believe that striving for excellence in what you do is the fundamental deterministic trait between good programmers and bad ones. Does anyone have any real world examples of how something written in a high level language—say Java, Pascal, PHP, or Javascript—truely benefitted from a prior knowledge of C? Examples would be most appreciated.

• LibGdx efficient data saving/loading?

  - by grimrader22

  Currently, my LibGDX game consists of a 512 x 512 map of Tiles and entities such as players and monsters. I am wondering how to efficiently save and load the data of my levels. At the moment I am using JSON serialization for each class I want to save. I implement the Json.Serializable interface for all of these classes and write only the variables that are necessary. So my map consists of 512 x 512 tiles, that's 260,000 tiles. Each tile on the map consists of a Tile object, which points to some final Tile object like a GRASS_TILE or a STONE_TILE. When I serialize each level tile, the final Tile that it points to is re-serialized over and over again, so if I have 100 Tiles all pointing to GRASS_TILE, the data of GRASS_TILE is written 100 times over. When I go to load/deserialize my objects, 100 GrassTile objects are created, but they are each their own object. They no longer point to the final tile object. I feel like this reading/writing files very slow. If I were to abandon JSON serialization, to my knowledge my next best option would be saving the level data to a sql database. Unless there is a way to speed up serializing/deserializing 260,000 tiles I may have to do this. Is this a good idea? Could I really write that many tiles to the database efficiently? To sum all this up, I am trying to save my levels using JSON serialization, but it is VERY slow. What other options do I have for saving the data of so many tiles. I also must note that the JSON serialization is not slow on a PC, it is only VERY slow on a mobile device. Since file writing/reading is so slow on mobile devices, what can I do?

• How do search engines handle hyphenated words?

  - by NinjaKC

  I am not sure my title fully explains what I mean. I thought this might be an interesting question. If I had a set of keywords, broken with a dash or 2, will search engines consider the dashed split keyword as maybe a full keyword? Say I have a site that sort of breaks words down, like the dictionary sites do. So a keyword for that page, might end up in the page, and / or the URL, as broken by dashes. Key-word = keyword Co-op-er-at-ive = cooperative Pho-to-gra-phy = Photography www.example.com/key-word/ www.example.com/co-op-er-at-ive/ www.example.com/pho-to-gra-phy/ I know search engines will consider a dash (at least Google) as a space, and understand it as multiple words. But in the English language, a dash can also break a word down (at least I think it can, can't it?), so will search engines also take this into consideration? I did a 'little' research, I Googled some words and placed random dashes, and it returned the words I searched for, but this could be considered a typo from the user on Google's search end, so really I am wondering if I can purposely put a dash in a keyword, and have the search engine spiders still catch that keyword as the real word without dashes? I've done a little Googling and looking here on Stackoverflow, but everything comes down to dashes for multiple words, not really the specific thing I'm trying to figure out. Hopefully that makes sense, I am not an expert in SEO, yet, but get the basics and have been playing, and this is just really a random question to satisfy my knowledge of playing :P

• Learning from jQuery - Solid fundament for experienced jQuery developers

  Frankly speaking, I had to sleep a night over before typing this review. And even now it is not an easy, straight-forward task to write this recension. I'm not sure whether I'm the right kind of audience this title is actually addressed to. It clearly states that this book is for web developers which are very familiar with jQuery library but would like to extend their knowledge to vanilla JavaScript. Not being part of this particular group it felt strange to go through the various chapters after all. This title is clearly addressed to experienced jQuery users and developers especially while looking for improvements in performance and better ways of optimisations. Sometimes just to simplify the existing jQuery code in order to avoid the heavy load of the complete jQuery library and sometimes for the better understanding of JavaScript and its syntax. Callum's style of writing is clear and the numerous code samples used to emphasize the various techniques are good ones and easy to understand. Quite interestingly, it put a light smile on my face when I compared his sample code of sending an AJAX request to some code in one of my own blog articles I wrote back in 2006 (in German language). JavaScript is clearly a mature language and certain requirements are simply done this way. And Callum explains the nuts and bolts of JavaScript very well. Personally, I gained most out of this book from chapter 5 - JavaScript Conventions. The paragraphs and code snippets on Optimizations and Common Antipatterns gave me a better understanding on various aspects of JavaScript development, and I definitely have to revise a couple of code fragments I have written in the past. Overall the book provides solid information on JavaScript for jQuery developers and is worth the money spent. Just be sure that you're part of the targeted audience.

• I'm a student learning C++ and I've recently found out about Ruby. Would learning (some of) Ruby help me with C++ or would it just confuse me?

  - by Von32

  As the title says, I'm a student that will be starting my second year of C++ very soon. I've discovered Ruby, however. While I've heard much buzz about the language before, I've disregarded it because I always thought it wasn't something that would be useful. However, I've found a number of FANTASTIC tutorials on ruby and am interested in learning it (probably because it seems so straightforward). Would playing around with ruby be a good or bad idea? I understand that there's not such thing as bad knowledge, but I'm afraid that Ruby will only confuse me when dealing with C++. How different from C++ is it? I've read it's based on C in some way. I've read some posts on here that Ruby and C++ can hold hands once in a while. How flexible is this relationship? Is it rarely that this would work? How useful is Ruby in the real world? I'm not specifically asking about jobs- I'm more interested in what sort of applications may come from this language. Any specific examples worth looking at?

• Masters or Second Bachelors Degree..or neither

  - by drD

  I have a degree in Business Administration, because at the time I didn't know what I wanted to do. I have been interested in programming for the past 2 years and have taken some action to self-teach. My experience/ knowledge base is limited to the following: -Read Kochan's Programming in C -Read IOS and Objective-C from the Big Nerd Ranch series -Obtained a C++ at NYU - thought it would be a good way to start to get a grasp on OO & design I would like to continue developing my skills, but most of all, re-orient how I am perceived as a professional. I am fully aware of how much a novice to this subject and would greatly appreciate any guidance anyone could give me. I currently have a job so full-time is not an option My goal is to become a software/ applications developer My questions are: -Should i take up a second bachelors in computer science? or a masters? or continue taking professional certificate programs (how are these viewed?) -If masters in computer science, would that make sense, if I dont have the formal foundation? (being a chief without ever being an Indian) -General advice for a novice to develop skill Thank You in advanced for helping me out.

• Help with "advanced" shell scripting | how to create an image preview of a pdf

  - by lucapozzobon

  First of all, sorry for my english: i'm not british/american. Here is my problem. I've got a folder named pdf with lots of files pdf inside it. I've got another folder named thumbnail, which is empty. I want to create jpg images preview of each pdf to use them in my HTML webpages as previews of the pdf. To do this I'm using a software called IMAGEMAGICK. I tried to put the code inside my PHP files to get the purpose, but it doesn't work. As you understood, I have created a small search engine with apache, mysql to search for pdf locally (offline). Now I want to add a "preview" of the first page of pdfs. Instead, it works by bash command line and the code is: convert pdf/name_of_the_file_pdf.pdf[0] name_of_the_imagefile.jpg (The zero stands for that the image is taken from the FIRST page of pdf) How can i make a script that takes each name of pdf files and put it into that code???? To list all the file, I did ls >pdf but with the little knowledge I have I can't go further.... Some pdf's names contain spaces....Is that a problem? PDF files are so many that i can't do the task typing every name,it wouldn't be a nice and clever work!!!! Thanks a lot in advance!!!

• [Dear Recruiter] I developed in Mo'Fusion

  - by refuctored

  Forward: Sometimes I really feel like technology recruiters have no experience or knowledge of the field they are recruting for.  A warning to those companies hiring technical recruiters -- ensure that the technical recruiters you hire to fill a position are actually technical.  Here's proof below, where I make up completely ridiculous technologies, but still have interest from the recruiter for an interview. Letter to me: Hello - Your name came up as a possible match for a long term contract Cold Fusion Developer role I have in Bothell, WA.  This role requires you to be onsite in Bothell, WA. This is  a tough role to fill so I was hoping you might have someone you can recommend? Unfortunately no telecommute. Thank you! Sincerly, Mindy Recruiter My response: Mindy -- Wow I'm super-excited that you took the time to contact me about this position!  Let me tell you, you won't be disappointed with my skill set! Firstly, I've been developing in ColdFusion since 1993 before it was owned by Adobe and it was operating under code name, "Hot-Jack".  Recently I started developing under the Domain-View-Driven-Domain-Model (DVDDM), integrating client-side CF on Moobuntu.  Not only do I have a boat load of ColdFusion EXP,  I also have a ton of experience in the open source communities lesser known derivative of CF, Mo'Fusion (MF).  I've also invested thousands of hours of my time learning esoteric programming languages. Look forward to working with you! George And her response: Hi George – just left you a message. Give me a call at your convenience.  The role does require someone to be onsite here.. are you able to relocate yourself? Mindy [Sigh]

• How to learn the math behind the code?

  - by Solomon Wise

  I am a 12 year old who has recently gotten into programming. (Although I know that the number of books you have read does not determine your programming competency or ability, just to paint a "map" of where I am in terms of the content I know...) I've finished the books: Python 3 For Absolute Beginners Pro Python Python Standard Library by Example Beautiful Code Agile Web Development With Rails and am about halfway into Programming Ruby. I have written many small programs (One that finds which files have been updated and deleted in a directory, one that compares multiple players' fantasy baseball value, and some text based games, and many more). Obviously, as I'm not some sort of child prodigy, I can't take a formal Computer Science course until high school. I really want to learn computer science to increase my knowledge about the code, and the how the code runs. I've really become interested in the math part after reading the source code for Python's random module. Is there a place where I can learn CS, or programming math online for free, at a level that would be at least partially understandable to a person my age?

• Feasability of mobile 2D multiplayer RPG game with interactive bitmap background

  - by user2827214

  I'm looking to develop a 2D multiplayer RPG game for Android, with a bird's eye view similar to that of zelda/pokemon. The game is very simple in all ways since my intent is for thousands of players to occupy the same world which I imagine requires good performance. However, I am unsure about the performance requirements of two properties: the tile map that is used as a background is dynamic (interactive). For example, a player steps in the water, and the water turns black. Every tile in the game does this. the tile map is the same object used for all players, but it is displayed differently on each user's mobile device, even though the players exist in the same world. For example, the water that turned black is displayed as red on all other players' screens. I have knowledge of java, but almost none regarding game dev. tools. Is there a best process for these requirements? Should I develop in pure java, or use some tool like Slick2D etc.? How performance intensive are these properties, if even possible? Edit: There are no collisions in the game or difficult animations, I am imagining simply changing the colors of the tiles (like in the examples), and a client-server architecture

• Are you at Super Computing 10?

  - by Daniel Moth

  Like last year, I was going to attend SC this year, but other events are unfortunately keeping me here in Seattle next week. If you are going to be in New Orleans, have fun and be sure not to miss out on the following two opportunities. MPI Debugging UX Study Throughout the week, my team is conducting 90-minute studies on debugging MPI applications within Visual Studio. In exchange for your feedback (under NDA) you will receive a Microsoft Gratuity (and the knowledge that you are impacting the development of Visual Studio). If you are interested, sign up at the Microsoft Information Desk in the Exhibitor Hall during exhibit hours. Outside of exhibit hours, send email to [email protected]. If you took part in the GPGPU study, this is very similar except it is for MPI. Microsoft High Performance Computing Summit On Monday 15th, the Microsoft annual user group meeting takes place. Shuttle transportation and lunch is provided. For full details of this event and to register, please visit the official event page. Comments about this post welcome at the original blog.

• The Oldest Big Data Problem: Parsing Human Language

  - by dan.mcclary

  There's a new whitepaper up on Oracle Technology Network which details the use of Digital Reasoning Systems' Synthesys software on Oracle Big Data Appliance.  Digital Reasoning's approach is inherently "big data friendly," as it leverages multiple components of the Hadoop ecosystem.  Moreover, the paper addresses the oldest big data problem of them all: extracting knowledge from human text.   You can find the paper here.   From the Executive Summary: There is a wealth of information to be extracted from natural language, but that extraction is challenging. The volume of human language we generate constitutes a natural Big Data problem, while its complexity and nuance requires a particular expertise to model and mine. In this paper we illustrate the impressive combination of Oracle Big Data Appliance and Digital Reasoning Synthesys software. The combination of Synthesys and Big Data Appliance makes it possible to analyze tens of millions of documents in a matter of hours. Moreover, this powerful combination achieves four times greater throughput than conducting the equivalent analysis on a much larger cloud-deployed Hadoop cluster.

• What web technology could I use which would support a decision tree?

  - by Rami Alhamad

  I am a big game development fan but I haven't done any commercial work in the past. I have been asked by a non-profit to look at developing a game similar to the award-winning www.playspent.org They want the following features: support 5 scenarios mobile isn't important but compatibility with older browsers would be a big bonus they want it to be visual and audible bonus is to have it easily modifiable support 4 languages I don't have much knowledge of Flash and would rather avoid using it as a solution. I started breaking down the problem into segments that I will need to examine, they are as follows: ability to read the game flow from a file that they can produce (xml, etc.) db design to store decision tree language challenge browser compatibility I am leaning towards an Google app engine/GWT solution but I am not sure what technology is best for this. I am really hoping to get your opinion/recommendation on my approach and on what technology is best. A special thanks (and beer if you live in Toronto) will be awarded to anyone who can help give me a ballpark estimate on how much such a game should go for. I know it's tough to estimate but any rough figure will help (how much would you charge for building something like playspent.org?) Thanks in advance
