  • What does RESTful web applications mean? [closed]

    - by John Cooper
    Possible Duplicate: What is REST (in simple English) What does RESTful web applications mean? A web service is a function that can be accessed by other programs over the web (Http). To clarify a bit, when you create a website in PHP that outputs HTML its target is the browser and by extension the human being reading the page in the browser. A web service is not targeted at humans but rather at other programs. SOAP and REST are two ways of creating WebServices. Correct me if i am wrong? What are other ways i can create a WebService? What does it mean fully RESTful web Application?

  • 'dock' working in simple words

    - by Shirish11
    I would like to know the idea behind the working of 'docking' in applications. I have worked with applications where components from individual forms are docked on a single main form to provide the necessary GUI. But I don't have any idea whats happening in the background. According to Wikipedia A dock is a graphical user interface element that typically provides the user with a way of launching, switching between, and monitoring running programs or applications. Now I am a bit confused if it is some component or an event or a property or something else. EDIT : The applications was developed in Delphi on windows platform. There is something more in Delphi (manual dock and automatic dock).

  • How to program something with the expectation that it will work the first time?

    - by Peter Turner
    I had a friend in college who programmed something that worked the first time, that was pretty amazing. But as for me, I just fire up the debugger as soon as I finally get whatever I'm working on to compile - saves me time (kidding of course, I sometimes hold out a little bit of hope or use a lot of premeditated debug strings). What's the best way to approach the Dijkstrain ideal for our programs? -or- Is this just some sort of pie-in-the-sky old fools quest for greatness applicable only to finite tasks that no one should hope for in our professional lives because programming is just too complex?

  • First Windows Phone 7 &ndash; Mobile LOB App.

    - by Richard Jones
    So I spent a couple of hours yesterday building my first Windows 7 Phone Series. application.   I still can’t get used to saying Windows 7 Phone Series.   So I think I’ll just go with WP7.   I must say I’m really impressed.    Calling web-services a breeze laying out User Interface a very straight forward.   I had made called into Dynamics NAV using web-services in under 10 minutes. Working in XAML takes a bit of getting used to,  I’m not trying to-do anything too clever yet. One thing I will point out to transition from one XAML page to the next use this.NavigationService.Navigate(new Uri("/Primary.xaml", UriKind.Relative)); Going from Compact Framework this is equivalent of a Window.Show Its so nice to be able to talk nicely again, about Windows Based Mobile Development!

  • Screenshot Tour: 10 New Features in Android 4.2 Jelly Bean

    - by Chris Hoffman
    Android 4.2 improves on Android 4.1 in numerous ways, adding a variety of new features. Android 4.2 isn’t as big an update as Android 4.1, also called Jelly Bean, but it’s a definite improvement. If you have a Nexus 7 or Galaxy Nexus, you should be getting this update very soon. Unfortunately, it will likely take quite a bit longer for manufacturers to ship Android 4.2 on non-Nexus devices.

  • Accessing files in a directory without x-permission?

    - by Leo
    I am having a bit of trouble understanding what the execute permission means for directories. Do I understand it correctly that anything in a directory for which a user does not have x-rights is inaccessible even if the things inside the directory gives specific rights to the user? Or will the user still have direct access to the things in the directory, but simply cannot list what is in the directory? (What I am really trying to understand is how safe a directory is from access from other users if they do not have x-permission for it.)

  • Web Host for Small Rails-based CMS site [closed]

    - by clem
    Possible Duplicate: How to find web hosting that meets my requirements? I am building a site for someone that uses a Rails-based content management system that I built myself. All of the Rails deployment experience I have so far has been over small intranets. I'm looking at web hosts like rackspace, because it seems like they're well-suited for Rails deployment. However, for a site that's not going to have more than a couple of hundred hits a month (if even that), I'm not sure it's necessary. I've also used Dreamhost's Phusion Passenger deployment for small projects before, but it seems barely functional and not well-supported, and I've also used Heroku for deployment, but I think a regular web host may do a little bit better, as they'll need things like Google Apps for Gmail set up. If anyone could provide some guidance on this, I'd greatly appreciate it. I get confused when I see things on rackspace like "1.5c/hour", because I'm not sure how that gets computed.

  • Ubuntu 13.10 won't boot and hangs on a black screen

    - by Anonymous John
    I installed Ubuntu 13.10 64-bit today and I sat on the internet most of the day after installation. I shut the computer down and went bowling with my family. When I came back, I turned on my computer and it came to the boot screen as usual, but then the screen went black and stayed black. Can this be solved or do I have to install Ubuntu 13.04. My dad does not know about this and I do not want to get yelled at for an hour, so I need an answer before midnight mountain time, otherwise I will install Ubuntu 13.04 so I won't get yelled at in the morning.Thanks to anyone who answers this.

  • Load balancing on Ubuntu Server

    - by SabreWolfy
    I have Ubuntu 10.04.4 server (32-bit) installed on a headless quad-core machine with 2GB RAM. I'm running a command-line analysis which is analyzing a large amount of data, but which does not require a large amount of RAM. The tool does not provide any multi-threading, so the CPU load is sitting at 1.00 (or sometimes just a little over). I ran top and pressed 1 to see the load on each of the cores and noticed that "Cpu1" is always running at 100%. I thought that the load would be distributed between the cores, rather than loading one core all the time. I'm sure I've seen this load-balancing behaviour before in Ubuntu or Debian Desktop versions. Why would the Server edition work differently? The analysis will likely take several hours to run, so loading one core at 100% for many hours while the other 3 remain idle is surely not the best approach?

  • Make objects slide across the screen in random positions

    - by user3475907
    I want to make an object appear randomly at the right hand side of the screen and then slide across the screen and disapear at the left hand side. I am working with libgdx. I have this bit of code but it makes items fall from the top down. Please help. public EntityManager(int amount, OrthoCamera camera) { player = new Player(new Vector2(15, 230), new Vector2(0, 0), this, camera); for (int i = 0; i < amount; i++) { float x = MathUtils.random(0, MainGame.HEIGHT - TextureManager.ENEMY.getHeight()); float y = MathUtils.random(MainGame.WIDTH, MainGame.WIDTH * 10); float speed = MathUtils.random(2, 10); addEntity(new Enemy(new Vector2(x, y), new Vector2(-0, -speed))); }

  • How to keep a team well-trained?

    - by PierrOz
    Hi dear fellows, I'm currently mentoring a small team of 4 junior dev in small software company. They are very smart and often achieve their tasks with a high-quality job but I'm sure they still can do better - actually I have exactly the same feeling for myself :) -. Besides some of them are more "junior" than other. So I would like to find of a funny way to improve their CS skills (design, coding, testing, algorithmic...) in addition to the experience they acquire in their daily work. For instance, I was thinking of setting up weekly sessions, not longer than 2 hours, where we could get together to work on challenging CS exercises. A bit like a coding dojo. I'm sure the team would enjoy that but is it really a good idea? Would it be efficient in a professional context? They already spend all their week to code so how should I organize that in order for them to get some benefits? Any feedback welcome !

  • Rules for Naming

    - by PointsToShare
    © 2011 By: Dov Trietsch. All rights reserved Naming Documents (or is it “Document, Naming”?) Tis but thy name that is my enemy; Thou art thyself, though not a Montague. What's Montague? It is nor hand, nor foot, Nor arm, nor face, nor any other part Belonging to a man. O, be some other name! What's in a name? That which we call a rose By any other name would smell as sweet; So Romeo would, were he not Romeo call'd, Retain that dear perfection which he owes Without that title. Romeo, doff thy name And for that name which is no part of thee Take all myself.  Shakespeare – Romeo and Juliet Act II, Scene 2 We normally only use the bold portion of the famous Shakespearean quote above, but it is really out of context. As the play unfolds, we learn that a name is all too powerful. Indeed it is because of their names that the doomed lovers die. There might be life and death in a name (BTW, when I wrote this monogram, I was in Hatfield, PA. Remember the Hatfields and the McCoys?) This is a bit extreme, but in the field of Knowledge Management (KM) names are of the utmost importance as well. When I write an article about managing SharePoint sites, how should I name it? “Managing a site” or “Site, managing”? Nine times out of ten I’d opt for the latter. Almost everything we do is “Managing” so to make life easier for a person looking for meaningful content, we title our articles starting with the differentiator rather than the common factor. As a rule of thumb, we start the name with the noun rather than the verb. It is not what we do that is the primary key; it is what we do it to. So, answer this – is it a “rule of thumb” or a “thumb rule?” This is tough. A lot of what we do when naming is a judgment call. Both thumb and rule are nouns, albeit concrete and abstract (more about this later), but to most people “thumb rule” is meaningless while “rule of thumb” is an idiom. The difference between knowledge and information is that knowledge is meaningful information placed in context. Thus I elect the “rule of thumb”. It is the more meaningful title. Abstract and Concrete are relative terms. Many nouns (and verbs) that are abstract to a commoner, are concrete to a practitioner of one profession or another and may even have different concrete meanings in different professional jargons. Think about “running”. To an executive it means running a business, to a marathoner its meaning is much more literal. Generally speaking, we store and disseminate knowledge within a practice more than we do it in general. Even dictionaries encyclopedias define terms as they apply to different audiences. The rule of thumb is to put the more concrete first, but within the audience’s jargon. Even the title of this monogram is a question. Do I name it “Naming Documents” or “Documents, Naming”? Well, my own rule of thumb (“Here he goes again!?”) states that the latter is better because it starts with a noun, but this is a document about naming more than it about documents. The rules of naming also apply to graphs and charts, excel spreadsheets, and so on. Thus, I vote for the former.  A better title could have been “Naming Objects” only the word “Object” is a bit too abstract. How about just “Naming” or “Naming, rules of”? You get the drift. One of the ways to resolve all of this is to store the documents in Knowledge-Bases, which may become the subjects of a future punditry. Knowledge bases use keywords to describe their content.  Use a Metadata store for the keywords to at least attempt some common grounds. Here is another general rule (rule of thumb?!!) – put at least the one keyword in the title. Use subtitles. Here is an example: Migrating documents – Screening, cleaning, and organizing our knowledge. The main keyword is “documents”, next is “migrating”, other keywords also appear in the subtitle. They are “screening”, “cleaning”, and “organizing”. Any questions? Send me an amply named document by email: [email protected]

  • Summit reflections

    - by Rob Farley
    So far, my three PASS Summit experiences have been notably different to each other. My first, I wasn’t on the board and I gave two regular sessions and a Lightning Talk in which I told jokes. My second, I was a board advisor, and I delivered a precon, a spotlight and a Lightning Talk in which I sang. My third (last week), I was a full board director, and I didn’t present at all. Let’s not talk about next year. I’m not sure there are many options left. This year, I noticed that a lot more people recognised me and said hello. I guess that’s potentially because of the singing last year, but could also be because board elections can bring a fair bit of attention, and because of the effort I’ve put in through things like 24HOP... Yeah, ok. It’d be the singing. My approach was very different though. I was watching things through different eyes. I looked for the things that seemed to be working and the things that didn’t. I had staff there again, and was curious to know how their things were working out. I knew a lot more about what was going on behind the scenes to make various things happen, and although very little about the Summit was actually my responsibility (based on not having that portfolio), my perspective had moved considerably. Before the Summit started, Board Members had been given notebooks – an idea Tom (who heads up PASS’ marketing) had come up with after being inspired by seeing Bill walk around with a notebook. The plan was to take notes about feedback we got from people. It was a good thing, and the notebook forms a nice pair with the SQLBits one I got a couple of years ago when I last spoke there. I think one of the biggest impacts of this was that during the first keynote, Bill told everyone present about the notebooks. This set a tone of “we’re listening”, and a number of people were definitely keen to tell us things that would cause us to pull out our notebooks. PASSTV was a new thing this year. Justin, the host, featured on the couch and talked a lot of people about a lot of things, including me (he talked to me about a lot of things, I don’t think he talked to a lot people about me). Reaching people through online methods is something which interests me a lot – it has huge potential, and I love the idea of being able to broadcast to people who are unable to attend in person. I’m keen to see how this medium can be developed over time. People who know me will know that I’m a keen advocate of certification – I've been SQL certified since version 6.5, and have even been involved in creating exams. However, I don’t believe in studying for exams. I think training is worthwhile for learning new skills, but the goal should be on learning those skills, not on passing an exam. Exams should be for proving that the skills are there, not a goal in themselves. The PASS Summit is an excellent place to take exams though, and with an attitude of professional development throughout the event, why not? So I did. I wasn’t expecting to take one, but I was persuaded and took the MCM Knowledge Exam. I hadn’t even looked at the syllabus, but tried it anyway. I was very tired, and even fell asleep at one point during it. I’ll find out my result at some point in the future – the Prometric site just says “Tested” at the moment. As I said, it wasn’t something I was expecting to do, but it was good to have something unexpected during the week. Of course it was good to catch up with old friends and make new ones. I feel like every time I’m in the US I see things develop a bit more, with more and more people knowing who I am, who my staff are, and recognising the LobsterPot brand. I missed being a presenter, but I definitely enjoyed seeing many friends on the list of presenters. I won’t try to list them, because there are so many these days that people might feel sad if I don’t mention them. For those that I managed to see, I was pleased to see that the majority of them have lifted their presentation skills since I last saw them, and I happily told them as much. One person who I will mention was Paul White, who travelled from New Zealand to his first PASS Summit. He gave two sessions (a regular session and a half-day), packed large rooms of people, and had everyone buzzing with enthusiasm. I spoke to him after the event, and he told me that his expectations were blown away. Paul isn’t normally a fan of crowds, and the thought of 4000 people would have been scary. But he told me he had no idea that people would welcome him so well, be so friendly and so down to earth. He’s seen the significance of the SQL Server community, and says he’ll be back. It’ll be good to see him there. Will you be there too?

  • What does the kernel boot parameter "set acpi_osi=Linux" do?

    - by AIB
    I am facing an issue with brightness control in my laptop which has Intel HD graphics. So when I searched for a fix I found that a common suggestion is to edit the GRUB file line, GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux acpi_backlight=vendor" So could anyone tell me what the kernel boot option acpi_osi=Linux do? My OS is Ubuntu 10.10 64-bit version update The boot parameter acpi_osi is used as follows, acpi_osi= [HW,ACPI] Modify list of supported OS interface strings acpi_osi="string1" # add string1 -- only one string acpi_osi="!string2" # remove built-in string2 acpi_osi= # disable all strings But still I don't find a reason why this should fix any laptop issue!!

  • WUBI installation on Lenovo u310

    - by Tom
    I recently installed 12.04 through the WUBI on a Lenovo u310. The installation went fine, but when I rebooted into Windows 7, and then rebooted into Ubuntu, it immediately went to a command line 'grub' prompt. I was able to reboot from there successfully into 12.04 (once) but then on another occasion could do nothing to reboot into Ubuntu, so had to reinstall. The reason I used the WUBI route was that there are troubles in 12.04 recognizing the hard drives on Lenovo u310 on direct install from memory stick. This has been a bit frustrating, and I was surprised by the difficulties on the Lenovo u310.

  • What does a Game Designer do? what skills do they need?

    - by xenoterracide
    I know someone who is thinking about getting into game design, and I wondered, what does the job game designer entail? what tools do you have to learn how to use? what unique skills do you need? what exactly is it you'd do from day to day. I may be wording this a bit wrong because I'm not sure if the college program is become a game designer or learn game design. but I think the same questions apply either way.

  • Go up one directory in mod_rewrite

    - by Rudolph Gottesheim
    I've got a standard Zend Framework 1 project that looks a bit like this: Project |- public |- .htaccess |- index.php The .htaccess looks like this: RewriteEngine On RewriteBase / RewriteRule ^image/.*$ img.php?file=$1 [NC,L] RewriteCond %{REQUEST_FILENAME} -s [OR] RewriteCond %{REQUEST_FILENAME} -l [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^.*$ - [NC,L] RewriteRule ^.*$ index.php [NC,L] Now I want to start transitioning the site to Zend Framework 2, which I put in a separate directory in the root, so the whole thing looks like this: Project |- public |- .htaccess |- index.php |- zf2 |- public |- .htaccess |- index.php What would I have to change in my original (ZF1) .htaccess to route all requests to (for example) /zf2/whatever to ZF2's index.php? I've tried RewriteRule ^zf2(/.*)$ ../zf2/public/index.php [NC,L] in the line after RewriteBase /, but that just gives me a 400 Bad Request.

  • Best way to slice up a non rectangular image?

    - by Hoff
    I have the image below and need to create a rollover for each "piece" or arrow in the circle. Because the image isn't rectangular, it boggles how me how I'm going to do this without having badly overlapping pieces. As you can see from the image below, the slices will overlap each other (quite a bit), which will not be good for the rollover. Does anybody have any ideas as to how to accomplish this without resorting to Flash or HTML5? The majority of our site's users use dinosaur browsers that don't support HTML5. Here's the link to the image: http://img812.imageshack.us/img812/3166/wheela.png

  • Microsoft Access 2010: How to Format Forms

    For the purpose of this tutorial, we will be working on formatting a form that people can use to enter in a customer's information. As is, the form is decent and usable, but what if you want to change its look around so that it has a custom look? What if you want to tweak its settings so that it better reflects your company or brand? That is exactly what we are about to do. The process is very simple and can even be a bit fun as you get creative with it. The reasoning behind formatting a form in Microsoft Access 2010 is rather logical. If someone is going to be using a form on a daily bas...

  • Placing of copyright notice in source code

    - by Diana Dcn
    I'm about to release a project of mine that I'm really proud of under the GNU GPL and I have some questions: Should one attach a copyright notice on each and every source code file from their project? I think it's a bit ridiculous to claim copyright on a 3 line abstract class. Should I attach a copyright notice only to really important source code files? Can I not attach the whole standard thingy? Because it's big and bulky and gets in the way... If so, is the variant below ok/enough? Copyright year firstname lastname.

  • Anti aliasing problem

    - by byronyasgur
    I am auditioning fonts on google web fonts and one that I was discounting was Ubuntu because it looked a bit jagged ( screenshot below taken straight from google); however afterward I read an article where it was mentioned as a good choice, and there was a screenshot where it looked really good ( to me anyway ). I am using windows 7 and have tried looking at it in chrome and firefox. I notice the same thing with some other fonts but this one is a good example because it looks perfect in the screenshot but not so good when I look at it on their site. I know this essentially is a question about setting my computer, but I thought that this would be the best place to pose the question: Is there something wrong with the settings on my machine seeing as it's obviously not showing the font the same on my computer as it did when the article writer downloaded it and used it in an image. The screenshot from Google ... The screenshot from the article above ...

  • Is Microsoft Prism alive and active?

    - by Mike
    I've been doing a lot of reading these last two days on Microsoft Prism, but the thing I'm still not very sure of is what does the future look like for it? I know that version 4.1 was just released a few months ago, but besides Microsoft's own documentation, I haven't found many blog posts written in the last year on the subject, most of what I find is 2009-2010. It definitely looks interesting but the learning curve seems to be a bit steep and I wouldn't want to embark if it's going to become obsolete in the near future. Anyone has any insight on this?

  • After reinstalling ATI graphics drivers, my keyboard and mous aren't working anymore

    - by Lifelike27
    On Ubuntu 11.04 I tried to install the open source drivers for my laptops ATI Mobility Radeon 5470M but I messed that up a bit and lost xserver. Now I've managed to solve that problem with this and by downloading the ATI proprietary drivers and install those manually. Now, when Ubuntu loads up I get to the login screen but I can't use my mouse or my keyboard (usb keyboard and mouse doesn't work either). If I use the recovery console, then login with that and then run 'startx'. I can login fine (though Unity doesn't show, the graphics seem to be working because it shows the fading animation of libnotify), but I can't type or move my mouse.
