  • Store HighRes photos in Database or as File?

    - by David
    I run a site which has a couple of million photos and gets over 1000 photos uploaded each day. Up to now, we haven't kept the original file that was uploaded to conserve on space. However, we are getting to a point that we are starting to see a need to have high-res original versions. I was wondering if its better to store these in the filesystem as an actual file or if its better to store them in a database (ie: mysql). The highres images would be rarely referenced but may be used when someone decides to download it or we decide to use it for rare processes like making a new set of thumbnails sizes/etc.

  • Can I assume interface oriented programming as a good object oriented programming?

    - by david
    I have been programming for decades but I have not been used to object oriented programming. But for recenet years, I had a great opportunity to learn OOP, its principles, and a lot of patterns that are great. Since I've learned OOP, I tried to apply them to a couple of projects and found those projects successful. Unfortunately I didn't follow extreme programming that suggests writing test first, mainly because their time frame were tight. What I did for those projects were Identify all necessary classes and create them with proper properties and methods whenever there is dependency between classes, write interface between them see if there is any patterns for certain relationships between classes to replace By successful, I meant that it was quick development effort, the classes can be reused better, and flexible enough so that another programmer does not have to change something else to fix another part. But I wonder if this is a good practice. Of course, I know I need to put writing unit tests first in my work process. But other than that, is there any problem with this approach - creating lots of interfaces - in long term?

  • Can I migrate a clone of Google Code repository into Github?

    - by David Conde
    I want to create a clone of a Google Code repository, which I cannot download due to Country restrictions and I want to migrate that clone into Github, which I can use without any problem. The thing is I have a Github account and I can browse through GoogleCode but I cannot take my TortoiseHg and clone a repo just like that because I'm from Cuba and I get a lovely Google page saying that I cannot go into Google code. I'm guessing you know how I manage to browse :) I would like to import a mercurial repository into my Github repo, my questions: Is it possible? How can I do it?

  • Top Questions and Answers for Pluging into Oracle Database as a Service

    - by David Swanger
    Yesterday we hosted a comprehensive online forum that shared a comprehensive path to help your organization design, deploy, and deliver a Database as a Service cloud. If you missed the online forum, you can watch it on demand by registering here. We received numerous questions.  Below are highlights of the most informative: DBaaS requires a lengthy and careful design efforts. What is the minimum requirements of setting up a scaled-down environment and test it out? You should have an OEM 12c environment for DBaaS administration and then a target database deployment platform that has the key characteristics of what your production environment will look like. This could be a single server or it could be a small pool of hosts if your production DBaaS will be larger and you want to test a more robust / real world configuration with Zones and Pools or DR capabilities for example. How does this benefit companies having their own data center? This allows companies to transform their internal IT to a service delivery model for the database. The benefits to the company are significant cost savings, improved business agility and reduced risk. The benefits to the consumers (internal) of services if much fast provisioning, and response to change in business requirements. From a deployment perspective, is DBaaS's job solely DBA's job? The best deployment model enables the DBA (or end-user) to control the entire process. All resources required to deploy the service are pre-provisioned, and there are no external dependencies (on network, storage, sysadmins teams). The service is created either via a self-service portal or by the DBA. The purpose of self service seems to be that the end user does not rely on the DBA. I just need to give him a template. He decides how much AMM he needs. Why shall I set it one by one. That doesn't seem to be the purpose of self service. Most customers we have worked with define a standardized service catalog, with a few (2 to 5) different classes of service. For each of these classes, there is a pre-defined deployment template, and the user has the ability to select from some pre-defined service sizes. The administrator only has to create this catalog once. Each user then simply selects from the options offered in the catalog.  Looking at DBaaS service definition, it seems to be no different from a service definition provided by a well defined DBA team. Why do you attribute it to DBaaS? There are a couple of perspectives. First, some organizations might already be operating with a high level of standardization and a higher level of maturity from an ITIL or Service Management perspective. Their journey to DBaaS could be shorter and their Service Definition will evolve less but they still might need to add capabilities such as Self Service and Metering/Chargeback. Other organizations are still operating in highly siloed environments with little automation and their formal Service Definition (if they have one) will be a lot less mature today. Therefore their future state DBaaS will look a lot different from their current state, as will their Service Definition. How database as a service impact or help with "Click to Compute" or deploying "Database in cloud infrastructure" DBaaS enables Click to Compute. Oracle DBaaS can be implemented using three architecture models: Oracle Multitenant 12c, native consolidation using Oracle Database and consolidation using virtualization in infrastructure cloud. As Deploy session showed, you get higher consolidating density and efficiency using Multitenant and higher isolation using infrastructure cloud. Depending upon your business needs, DBaaS can be implemented using any of these models. How exactly is the DBaaS different from the traditional db? Storage/OS/DB all together to 'transparently' provide service to applications? Will there be across-databases access by application/user. Some key differences are: 1) The services run on a shared platform. 2) The services can be rapidly provisioned (< 15 minutes). 3) The services are dynamic and can be relocated, grown, shrunk as needed to meet business needs without disruption and rapidly. 4) The user is able to provision the services directly from a standardized service catalog.. With 24x7x365 databases its difficult to find off peak hrs to do basic admin tasks such as gathering stats, running backups, batch jobs. How does pluggable database handle this and different needs/patching downtime of apps databases might be serving? You can gather stats in Oracle Multitenant the same way you had been in regular databases. Regarding patching/upgrading, Oracle Multitenant makes patch/upgrade very efficient in that you can pre-provision a new version/patched multitenant db in a different ORACLE_HOME and then unplug a PDB from its CDB and plug it into the newer/patched CDB in seconds.  Thanks for all the great questions!  If you'd like to learn more and missed the online forum, you can watch it on demand here.

  • What do you use to bundle / encrypt data?

    - by David McGraw
    More and more games are going the data driven route which means that there needs to be a layer of security around easy manipulation. I've seen it where games completely bundle up their assets (audio, art, data) and I'm wondering how they are managing that? Are there applications / libraries that will bundle and assist you with managing the assets within? If not is there any good resources that you would point to for packing / unpacking / encryption? This specific question revolves around C++, but I would be open to hear how this is managed in C#/XNA as well. Just to be clear -- I'm not out to engineer a solution to prevent hacking. At the fundamental level we're all manipulating 0's and 1's. But, we do want to keep the 99% of people that play the game from simply modifying XML files that are used to build the game world. I've seen plenty of games bundle all of their resources together. I'm simply curious about the methods they're using.

  • Mobile and Social for Retail

    - by David Dorf
    I've got two speaking gigs in the next few weeks, so I thought I'd preview both here. First I'll be at eTail West on February 24th to talk about mobile. I'll be previewing a new study of how shoppers are using mobile phones. Here's a sneak peek at one of the slides: It should be no surprise that as more consumers adopt smartphones, more are finding ways to use them to help with shopping. Sometimes that's to find a store, download a coupon, or do price comparisons. I'll also be discussing the NRF Mobile Blueprint, and will walk through an example of mobile impacting the in-store experience. Retailers need to look upon mobile as the method of bringing the digital assets of e-commerce into the aisles to enhance shopping. On March 9th I'll be at NRF Innovate co-presenting with Jon Kubo of Wet Seal on social strategies. Jon is a retail innovation rock-star and I always learn something new from every conversation with him. Below is a another slide preview: I cheated a little on the top 10 most popular retailer pages by not including Victoria's Secret Pink. VC is already represented, so I didn't include them a second time. The most interesting statistic I found was that the average user spends 55 minutes on Facebook a day. Wow! I also decided to use the old "Like" and "Fan" icons just because I like them better (pun intended). Wet Seal has been collecting interesting statistics on liked products, so I hope Jon will share lots (I'm on a roll). Hope to see you at both events.

  • Commerce, Anyway You Want It

    - by David Dorf
    I believe our industry is finally starting to realize the importance of letting consumers determine how, when, and where to interact with retailers.  Over the last few months I've seen several articles discussing the importance of removing the barriers between existing channels. Paula Rosenblum of RSR first brought the term omni-channel to my attention back in September. She stated, "omni-channel retail isn’t the merging of channels – rather, it’s the use of all possible channels (present and future) to enhance the customer experience in a profitable way." I added to her thoughts in this blog posting in which I said, "For retailers to provide an omni-channel experience, there needs to be one logical representation of products, prices, promotions, and customers across all channels. The only thing that varies is the presentation of the content based on the delivery mechanism (e.g. shelf labels, mobile phone, web site, print, etc.) and often these mechanisms can be combined in various ways." More recently Brian Walker of Gartner suggested we stop using the term multi-channel and begin thinking more about consumer touch-points. "It is time for organizations to leave their channel-oriented ways behind, and enter the era of agile commerce--optimizing their people, processes and technology to serve today's empowered, ever-connected customers across this rapidly evolving set of customer touch points." Now Jason Goldberg, better known as RetailGeek, says we should start breaking down the channel silos by re-casting the VP of E-Commerce as the VP of Digital Marketing, and change his/her focus to driving sales across all channels using digital media. This logic is based on the fact that consumers switch between channels, or touch-points as Brian prefers, as part of their larger buying process. Today's smart consumer leverages the Web, mobile, and stores to provide the best shopping experience, so retailers need to make this easier. Regardless of what we call it, the key take-away is that "multi-channel" is not only an antiquated term but also an idea who's time has passed.  Today, retailers must look at e-commerce, m-commerce, f-commerce, catalogs, and traditional store sales collectively and through the consumers' eyes.  The goal is not to drive sales through each channel but rather to just drive sales -- using whatever method the customer prefers.  There really should be just one cart.

  • Naming the Weapons and Designing Weapons Based in Real-life During Game Development [duplicate]

    - by David Dimalanta
    This question already has an answer here: Do you need a license for weapon models? 6 answers Is it legit or copyright safe if I name the actual name of the gun model such as AK-47, M16, Remington 870, and so on? I'm on the works for making a simple 2D 3rd-person shooter game. One of the examples is the Counter Strike and the game listed the name of weapons based on the real life models and so developers decided to created this named it for the weapon designs. If not, should I make either falsify the name of weapons (e.g. 9mm instead of Glock 17 from a Syphon Filter game) or make fictional weapons like the ones developed behind Halo games?

  • Music Rhythm Game Difficulty Question

    - by David Dimalanta
    I have curious question about music rhythm based genre while I'm making a code for the game. Is it really better if I set a random pattern encountered on every music played or there is a specific pattern depending on the music and the difficulty? I have observed the Guitar Hero 3 game for the game console where the difficulty is set on the number of strings used and possible number of combo (e.g. two-string combo). Compared to the Tap Tap Revenge for the Android and iPhone, the difficulty based on the number of BPM (Beat per Minute), meaning, number of targets spawn and must be hit.

  • how to be a web developer [closed]

    - by David
    Well, I'm 34 years old, and I have a master degree in computer science, for some how I cannot get a job as a programmer when I was younger, so I got a job related to computer. Recently I work in content management system, and updating the content of web portals. I'm trying to be a web programmer, so I started learning the techniques for web development, and CMS. I have a good knowledge of PHP and Wordpress, but I have a problem when I apply for a job I got the answer "sorry, you have no experience!" how can I solve that, and get a career in programming and web development?

  • Precise Touch Screen Dragging Issue: Trouble Aligning with the Finger due to Different Screen Resolution

    - by David Dimalanta
    Please, I need your help. I'm trying to make a game that will drag-n-drop a sprite/image while my finger follows precisely with the image without being offset. When I'm trying on a 900x1280 (in X [900] and Y [1280]) screen resolution of the Google Nexus 7 tablet, it follows precisely. However, if I try testing on a phone smaller than 900x1280, my finger and the image won't aligned properly and correctly except it still dragging. This is the code I used for making a sprite dragging with my finger under touchDragged(): x = ((screenX + Gdx.input.getX())/2) - (fruit.width/2); y = ((camera_2.viewportHeight * multiplier) - ((screenY + Gdx.input.getY())/2) - (fruit.width/2)); This code above will make the finger and the image/sprite stays together in place while dragging but only works on 900x1280. You'll be wondering there's camera_2.viewportHeight in my code. Here are for two reasons: to prevent inverted drag (e.g. when you swipe with your finger downwards, the sprite moves upward instead) and baseline for reading coordinate...I think. Now when I'm adding another orthographic camera named camera_1 and changing its setting, I recently used it for adjusting the falling object by meter per pixel. Also, it seems effective independently for smartphones that has smaller resolution and this is what I used here: show() camera_1 = new OrthographicCamera(); camera_1.viewportHeight = 280; // --> I set it to a smaller view port height so that the object would fall faster, decreasing the chance of drag force. camera_1.viewportWidth = 196; // --> Make it proportion to the original screen view size as possible. camera_1.position.set(camera_1.viewportWidth * 0.5f, camera_1.viewportHeight * 0.5f, 0f); camera_1.update(); touchDragged() x = ((screenX + (camera_1.viewportWidth/Gdx.input.getX()))/2) - (fruit.width/2); y = ((camera_1.viewportHeight * multiplier) - ((screenY + (camera_1.viewportHeight/Gdx.input.getY()))/2) - (fruit.width/2)); But the result instead of just following the image/sprite closely to my finger, it still has a space/gap between the sprite/image and the finger. It is possibly dependent on coordinates based on the screen resolution. I'm trying to drag the blueberry sprite with my finger. My expectation did not met since I want my finger and the sprite/image (blueberry) to stay close together while dragging until I release it. Here's what it looks like: I got to figure it out how to make independent on all screen sizes by just following the image/sprite closely to my finger while dragging even on most different screen sizes instead.

  • How do I install iTunes?

    - by David
    I have an iPhone and run Ubuntu on all of my personal computers. Since I did not want to keep a separate partition with Windows on it for the sole purpose of running iTunes, I attempted to install It using Wine. I installed Wine 1.4 from the Software Center and installed iTunes 10.6.3. When I tried to run it I got a slew of error messages. I hopped over to google where it was suggested that I install it through PlayOnLinux. I did so with the same result. Further googling revealed that iTunes 10.6.x is confirmed to work with Wine 1.5.1 and up. I installed Wine 1.5.1 following the instructions I found and was unable to get it to open. I did the same with 1.5.9 with the same results. I opened the Package Manager and installed the Wine 1.5.9 packages through it, and it appears to have installed properly. When trying to install iTunes I got he error "This iTunes installer requires Windows Vista 64 bit or later". Realizing that Wine uses XP as a default I ran winecfg and changed it to Windows 7. This changed nothing and I tried changing it through winetricks to no avail. I even changed it to Vista with the same results. Does anyone know what is going wrong here and how to fix it? Thanks

  • Software cost estimation

    - by David Conde
    I've seen on my work place (a University) most students making the software estimation cost of their final diploma work using COCOMO. My guessing is that this way of estimating costs is somewhat old (COCOMO dates of 1981), hence my question: How do you estimate costs in your software? I've seen things like : Cost = ( HoursOfWork + EstimatedIddle ) * HourlyRate That's not what I want, I'm looking for a properly (scientifically) defined cost model EDIT I've found some related questions on SO: What are some of the software cost estimation methods and models? How do you estimate the cost of developing software requirements?

  • How do I share different files in a git repo with different people?

    - by David Faux
    In a single directory with a Git root folder, I have a bunch of files. I am working on one of those files, X.py, with my friend Alice. The other files I am working on with other people. I want Alice (and everyone else) to have access to X.py. I want Alice to only have access to X.py though. How can I achieve this with Git? Is there a way I can split a directory into two repos? That sounds rather cumbersome. Maybe I could add a remote repo that Alice can access containing X.py?

  • How exactly does XNA's SpriteBatch work?

    - by David Gouveia
    To be more precise, if I needed to recreate this functionality from scratch in another API (e.g. in OpenGL) what would it need to be capable of doing? I do have a general idea of some of the steps, such as how it prepares an orthographic projection matrix and creates a quad for each draw call. I'm not too familiar, however, with the batching process itself. Are all quads stored in the same vertex buffer? Does it need an index buffer? How are different textures handled? If possible I'd be grateful if you could guide me through the process from when SpriteBatch.Begin() is called until SpriteBatch.End(), at least when using the default Deferred mode.

  • Isometric algorithm producing tiles in wrong draw order

    - by David
    I've been toying with isometric and I just cant get the tiles to be in the right order. I'm probably missing something obvious and I just can't see it. Even at the risk of looking stupid, here's my code: for (int i = 0; i < Tile.MapSize; i++) { for (int j = 0; j < Tile.MapSize; j++) { spriteBatch.Draw( Tile.TileSetTexture, new Rectangle( (-j * Tile.TileWidth / 2) + (i * Tile.TileWidth / 2), (i * (Tile.TileHeight - 9) / 2) - (-j * (Tile.TileHeight - 9) / 2), Tile.TileWidth, Tile.TileHeight), Tile.GetSourceRectangle(tileID), Color.White, 0.0f, new Vector2(-350, -60), SpriteEffects.None, 1.0f); } } And here's what I end up with: messed up map Yep, bit of an issue. If anyone could help, I'd appreciate it.

  • Recommended installation for Asus EEE 1015PEM Netbook

    Hi, I just got my Asus EEE PC 1015PEM netbook with Windows 7 starter... obviously, I'd like to install Ubuntu (not sure yet if I'd like to dual boot or completely remove win7). Anyway, I never had a netbook before. I know about unity but heard some bad stuff about it, so I wonder if I might be better sticking to the desktop edition. What do you think? any recommendations? Also, should I use the 32 bit or 64 bit version?

  • Is there any way to adjust the width of taskbar items on Gnome desktop?

    - by David Thomas
    Is there any way in which the width of items on the taskbar (or, rather, the lower panel) of the Gnome (2.32.0) desktop (Ubuntu 10.10) can be adjusted to take a more sensible width? While I can see the icons of the applications they represent, they seem a little over-compressed, given the width of the desktop/monitor resolution (1900 x 1080): Click the image, or this link, for a full-sized (1920x169, 169.7KB) graphic.

  • Virtual screen size with libgdx and GLES 2

    - by David Saltares Márquez
    I've been trying to use a virtual screen size for my libgdx desktop-android game. I'd like to always use a 16:9 aspect ratio but with a virtual screen size so everything would adapt automatically depending on the device size. This post illustrates the process pretty well but my game crashes when camera.apply(Gdx.Gl10) is called. This is because I'm using GLES 2.0 (for not having to use multiple of 2 texture sizes). As stated in the OrthographicCamera doc, the apply method only works with GLES 1 and GLES 1.1. Is there another way of applying my GL transformation to the camera so I can use a virtual screen resolution? Having to resize everything manually it's a total pain. Thanks a lot.

  • How do I create a third Person View using DXUTCamera in DX10?

    - by David
    I am creating a 3d flying game and using DXUTCamera for my view. I can get the camera to take on the characters position, But I would like to view my character in the 3rd person. Here is my code for first person view: //Put the camera on the object. D3DXVECTOR3 viewerPos; D3DXVECTOR3 lookAtThis; D3DXVECTOR3 up ( 5.0f, 1.0f, 0.0f ); D3DXVECTOR3 newUp; D3DXMATRIX matView; //Set the viewer's position to the position of the thing. viewerPos.x = character->x; viewerPos.y = character->y; viewerPos.z = character->z; // Create a new vector for the direction for the viewer to look character->setUpWorldMatrix(); D3DXVECTOR3 newDir, lookAtPoint; D3DXVec3TransformCoord(&newDir, &character->initVecDir, &character->matAllRotations); // set lookatpoint D3DXVec3Normalize(&lookAtPoint, &newDir); lookAtPoint.x += viewerPos.x; lookAtPoint.y += viewerPos.y; lookAtPoint.z += viewerPos.z; g_Camera.SetViewParams(&viewerPos, &lookAtPoint); So does anyone have an ideas how I can move the camera to the third person view? preferably timed so there is a smooth action in the camera movement. (I'm hoping I can just edit this code instead of bringing in another camera class)

  • 2011 - ALMs for your development team and the people they work with.

    - by David V. Corbin
    Welcome to 2011, it is already shaping up to be a very exciting year. The title of the post is not about charitable giving, although that is also a great topic. Application Lifecycle Management and the Systems that support the environment is, and 2011 will be a year where I expect many teams to invest heavily in this area. For those not familiar with ALM, it can be simplified down to "A comprehensive view of all of the iteas, requirements, activities and artifacts that impact an application over the course of its lifecycle, from concept until decommissioning". Obviously, this encompases a large number of different areas even for relatively small and medium sized projects. In recent years, many teams have adapted methodoligies which address individual aspects of this; but the majority of this adoption has resulted in "islands of improvement" rather than the desired comprehensive outcome...Until now! Last year Microsoft released Team Foundation Server 2010 along with Visual Studio 2010 Ultimate Edition, and with these two in combination the situation has drastically changed. At last there is a single environment that is capable of handling all aspects of ALM, and is also capable of dealing with migration and integration with existing systems to make the transition to a single solution much easier. Thse possibilities (and practicalities) are nothing short of amazing, Architecture thru Testing integration? YES. Being able to correlate specific requirement items (and their history) to actual code (and code history)? YES. Identification of which tests will be potentially impacted by a given code change? YES. Resiliant Automated Testing of User Interfaces? YES. Automatic Deployment Management? YES. Integraton Level testing as part of (designated) Builds? YES. I could easily double or triple the above list, but these items should be enough to get you thinking about the "pain points" your team and organization currently face and the fact that there IS a way to relieve the pain. Over the course of the year, I am hoping to bring together some of the "best of breed" information, along with hosting (and participating in) discussions with various experts in the field. There are already a number of groups (including many on LinkedIn) that have an ALM focus, and I encourage everyone out to check them out. I will be posting a list of the ones I find most helpful in the not too distant future. As I said at the beginning, 2011 is shaping up to be a very interesting (and productive) year. Why wait to start investigating and adopting ALM? ps: For those interested in becoming an "Alms Giver" in the charitable sense, I highly recommend checking out GiveCamp. A group of developers, designers and others get together to create a solution for a charity in just under 48 hours. I will be attending the GiveCamp in New York City on Jan 14-16, more information is available at nycgivecamp.org/

  • Walmart's Mobile Self-Checkout

    - by David Dorf
    Reuters recently reported that Walmart was testing an iPhone-based self-checkout at a store near its headquarters.  Consumers scan items as they're placed in the physical basket, then the virtual basket is transferred to an existing self-checkout station where payment is tendered.  A very solid solution, but not exactly original. Before we go further, let's look at the possible cost savings for Walmart.  According to the article: Pushing more shoppers to scan their own items and make payments without the help of a cashier could save Wal-Mart millions of dollars, Chief Financial Officer Charles Holley said on March 7. The company spends about $12 million in cashier wages every second at its Walmart U.S. stores. Um, yeah. Using back-of-the-napkin math, I calculated Walmart's cashiers are making $157k per hour.  A more accurate statement would be saving $12M per year for each second saved on the average transaction time.  So if this self-checkout approach saves 2 seconds per transaction on average, Walmart would save $24M per year on labor.  Maybe.  Sometimes that savings will be used to do other tasks in the store, so it may not directly translate to less employees. When I saw this approach demonstrated in Sweden, there were a few differences, which may or may not be in Walmart's plans.  First, the consumers were identified based on their loyalty card.  In order to offset the inevitable shrink, retailers need to save on labor but also increase basket size, typically via in-aisle promotions.  As they scan items, retailers should target promos, and that's easier to do if you know some shopping history.  Last I checked, Walmart had no loyalty program. Second, at the self-checkout station consumers were randomly selected for an audit in which they must re-scan all the items just like you do at a typical self-checkout.  If you were found to be stealing, your ability to use the system can be revoked.  That's a tough one in the US, especially when the system goes wrong, either by mistake or by lying.  At least in my view, the Swedes are bit more trustworthy than the people of Walmart. So while I think the idea of mobile self-checkout has merit, perhaps its not right for Walmart.

  • Why must I restart for HDMI audio?

    - by David Shochat
    I have a System76 Lemur Ultra laptop, which has an HDMI port. When I plug in the HDMI cable, it is recognized immediately for video, but not for audio, i.e., it does not show up in the Output tab of the Sound Settings dialog. However, if I do a full restart with the cable plugged in, then it does show up and can be selected. I've also discovered that manually killing and restarting pulseaudio with the HDMI plugged in will force it to be recognized as an available audio output. So my question is, what is broken here? I've thought about writing a bug in launchpad, but I don't know which component is malfunctioning. Is it the kernel? ALSA? Pulse Audio? Something else? By the way, the same bug seems to exist in reverse, namely if I disconnect the HDMI, it is still listed in the Output tab until I again restart the OS. This is 12.04 LTS.
