• Stitch scanned images using CLI

  - by Adam Matan

  I have scanned a newspaper article which was larger than the scanner glass. Each page was scanned twice: the top and the bottom parts, where the middle part appeared in both images. Is there a way to quickly match and stitch these scanned images, preferably using CLI? The panorama stitching tools I know require lengthy configuration, which is mostly irrelevant: lens size, focus, angle etc. Hugin has a solution for this issue, but it isn't practical for batch jobs.

• How to facilitate code reviews in a small team for embedded software?

  - by Adam Lewis

  Short Question Does a cost-effective tool / workflow exist to facilitate code reviews in a small team? More specifically, a small team that relies on post-commit code reviews. Background Our team currently consists of 3 full time and 1 part time software engineers, with plans on hiring more in the near future. Due to our team size and volume of projects we all must juggle, the pre-commit workflow that major tools (such as Review Board and Code Collaborator) use is not obtainable for us right now. The best we can do at the moment is to perform post-commit reviews before major releases or as time permits. Nearly all of our projects are hosted on RepositoryHosting.com (which I highly recommend) and contain a mixture of SVN and GIT repositories. Current Thoughts Since I cannot find a tool that fits our needs right now, I am turning to TRAC that is built into our repository's site. At the moment we use TRAC to file tickets and track milestones, so to me this seems like a natural fit for code review results as well. The direction I am heading in right now is to use a spread sheet(s) to log all of the bugs and comments. Do some macro magic to get it in a format that I can use TRAC's import ticket method and use TRAC's ticketing system to create the action items / bug reports automatically. The auto ticket generation is darn near a must have, adding in bugs and comments one at a time from a web-gui is really painful. Secondary Question If this workflow makes sense, is there a good / standard template to use as a code review log?

• Staying OO and Testable while working with a database

  - by Adam Backstrom

  What are some OOP strategies for working with a database but keeping thing testable? Say I have a User class and my production environment works against MySQL. I see a couple possible approaches, shown here using PHP: Pass in a $data_source with interfaces for load() and save(), to abstract the backend source of data. When testing, pass a different data store. $user = new User( $mysql_data_source ); $user-load( 'bob' ); $user-setNickname( 'Robby' ); $user-save(); Use a factory that accesses the database and passes the result row to User's constructor. When testing, manually generate the $row parameter, or mock the object in UserFactory::$data_source. (How might I save changes to the record?) class UserFactory { static $data_source; public static function fetch( $username ) { $row = self::$data_source->get( [params] ); $user = new User( $row ); return $user; } } I have Design Patterns and Clean Code here next to me, but I'm struggling to find applicable concepts.

• Using hreflang to specify a catchall language

  - by adam

  We have a site primarily targeted at the UK market, and are adding a US-market alternative. As per Google's recommendations: To indicate to Google that you want the German version of the page to be served to searchers using Google in German, the en-us version to searchers using google.com in English, and the en-gb version to searchers using google.co.uk in English, use rel="alternate" hreflang="x" to identify alternate language versions. Which gives us: <link rel="alternate" hreflang="en-gb" href="http://www.example.com/page.html" /> <link rel="alternate" hreflang="en-us" href="http://www.example.com/us/page.html" /> We do get enquiries from other areas of the world - particularly where there are expat communities (Dubai, UAE, Portugal etc). By adding the above tags, is there a risk that Google will only surface our site for UK and US search users? Do we need to specify a catch-all that will default all other searches to our UK site?

• Sun Ray Hardware Last Order Dates & Extension of Premier Support for Desktop Virtualization Software

  - by Adam Hawley

  In light of the recent announcement  to end new feature development for Oracle Virtual Desktop Infrastructure Software (VDI), Oracle Sun Ray Software (SRS), Oracle Virtual Desktop Client (OVDC) Software, and Oracle Sun Ray Client hardware (3, 3i, and 3 Plus), there have been questions and concerns regarding what this means in terms of customers with new or existing deployments.  The following updates clarify some of these commonly asked questions. Extension of Premier Support for Software Though there will be no new feature additions to these products, customers will have access to maintenance update releases for Oracle Virtual Desktop Infrastructure and Sun Ray Software, including Oracle Virtual Desktop Client and Sun Ray Operating Software (SROS) until Premier Support Ends.  To ensure that customer investments for these products are protected, Oracle  Premier Support for these products has been extended by 3 years to following dates: Sun Ray Software - November 2017 Oracle Virtual Desktop Infrastructure - March 2017 Note that OVDC support is also extended to the above dates since OVDC is licensed by default as part the SRS and VDI products.   As a reminder, this only affects the products listed above.  Oracle Secure Global Desktop and Oracle VM VirtualBox will continue to be enhanced with new features from time-to-time and, as a result, they are not affected by the changes detailed in this message. The extension of support means that customers under a support contract will still be able to file service requests through Oracle Support, and Oracle will continue to provide the utmost level of support to our customers as expected,  until the published Premier Support end date.  Following the end of Premier Support, Sustaining Support remains an 'indefinite' period of time.   Sun Ray 3 Series Clients - Last Order Dates For Sun Ray Client hardware, customers can continue to purchase Sun Ray Client devices until the following last order dates: Product Marketing Part Number Last Order Date Last Ship Date Sun Ray 3 Plus TC3-P0Z-00, TC3-PTZ-00 (TAA) September 13, 2013 February 28, 2014 Sun Ray 3 Client TC3-00Z-00 February 28, 2014 August 31, 2014 Sun Ray 3i Client TC3-I0Z-00 February 28, 2014 August 31, 2014 Payflex Smart Cards X1403A-N, X1404A-N February 28, 2014 August 31, 2014 Note the difference in the Last Order Date for the Sun Ray 3 Plus (September 13, 2013) compared to the other products that have a Last Order Date of February 28, 2014. The rapidly approaching date for Sun Ray 3 Plus is due to a supplier phasing-out production of a key component of the 3 Plus.   Given September 13 is unfortunately quite soon, we strongly encourage you to place your last time buy as soon as possible to maximize Oracle's ability fulfill your order. Keep in mind you can schedule shipments to be delivered as late as the end of February 2014, but the last day to order is September 13, 2013. Customers wishing to purchase other models - Sun Ray 3 Clients and/or Sun Ray 3i Clients - have additional time (until February 28, 2014) to assess their needs and to allow fulfillment of last time orders.  Please note that availability of supply cannot be absolutely guaranteed up to the last order dates and we strongly recommend placing last time buys as early as possible.  Warranty replacements for Sun Ray Client hardware for customers covered by Oracle Hardware Systems Support contracts will be available beyond last order dates, per Oracle's policy found on Oracle.com here.  Per that policy, Oracle intends to provide replacement hardware for up to 5 years beyond the last ship date, but hardware may not be available beyond the 5 year period after the last ship date for reasons beyond Oracle's control. In any case, by design, Sun Ray Clients have an extremely long lifespan  and mean time between failures (MTBF) - much longer than PCs, and over the years we have continued to see first- and second generations of Sun Rays still in daily use.  This is no different for the Sun Ray 3, 3i, and 3 Plus.   Because of this, and in addition to Oracle's continued support for SRS, VDI, and SROS, Sun Ray and Oracle VDI deployments can continue to expand and exist as a viable solution for some time in the future. Continued Availability of Product Licenses and Support Oracle will continue to offer all existing software licenses, and software and hardware support including: Product licenses and Premier Support for Sun Ray Software and Oracle Virtual Desktop Infrastructure Premier Support for Operating Systems (for Sun Ray Operating Software maintenance upgrades/support)  Premier Support for Systems (for Sun Ray Operating Software maintenance upgrades/support and hardware warranty) Support renewals For More Information For more information, please refer to the following documents for specific dates and policies associated with the support of these products: Document 1478170.1 - Oracle Desktop Virtualization Software and Hardware Lifetime Support Schedule Document 1450710.1 - Sun Ray Client Hardware Lifetime schedule Document 1568808.1 - Document Support Policies for Discontinued Oracle Virtual Desktop Infrastructure, Sun Ray Software and Hardware and Oracle Virtual Desktop Client Development For Sales Orders and Questions Please contact your Oracle Sales Representative or Saurabh Vijay ([email protected])

• How to protect SHTML pages from crawlers/spiders/scrapers?

  - by Adam Lynch

  I have A LOT of SHTML pages I want to protect from crawlers, spiders & scrapers. I understand the limitations of SSIs. An implementation of the following can be suggested in conjunction with any technology/technologies you wish: The idea is that if you request too many pages too fast you're added to a blacklist for 24 hrs and shown a captcha instead of content, upon every page you request. If you enter the captcha correctly you've removed from the blacklist. There is a whitelist so GoogleBot, etc. will never get blocked. Which is the best/easiest way to implement this idea? Server = IIS Cleaning out the old tuples from a DB every 24 hrs is easily done so no need to explain that.

• Information about SATA, IDE (PATA) controllers

  - by Adam Matan

  I have a remote computer on which I want to install a new hard drive for rsync backup. The problem is, I don't know what controller technology is used (PATA, SATA, SATA2, ...) and how many available slots are left. I want to spare me an unnecessary drive just for opening the chassis and looking into wires. How do I query the SATA or PATA controllers? I'm interested in the following points: Which controllers exist in the machine How many (and which) disks are attached to each controller How many available slots are there

• Trying to implement fling events on an object

• How can I select an appropriate licensing/obfuscation system for .NET?

  - by Adam

  I saw someone suggesting .NET Reactor once as a good obfuscator. I went to their website to check it out and saw they have a product called IntelliLock which is advertised as a pretty robust licensing system which has code protection/obfuscation built in. With that said, I tried to contact them and ask them a few questions regarding the product, but have not had any response. This is kind of a red flag for me. However, it seems like there is some user base for this product whom are satisfied. What .NET licensing system(s) with .NET code protection/obfuscation are you using? What are its pros & cons that you have encountered? Are there things I should be looking for or looking to avoid when evaluating these systems?

• What's the best way to create animations when doing Android development?

  - by Adam Smith

  I'm trying to create my first Android game and I'm currently trying to figure out (with someone that will do the drawings and another programmer) what the best way to create animation is. (Animations such as a character moving, etc.) At first, the designer said that she could draw objects/characters and animate them with flash so she didn't have to draw every single frame of an action. The other programmer and I don't know Flash too much so I suggested extracting all the images from the Flash animation and making them appear one after the other when the animation is to start. He said that would end up taking too much resource on the CPU and I tend to agree, but I don't really see how we're supposed to make smooth animations without it being too hard on the hardware and, if possible, not have the designer draw every single frame on Adobe Illustrator. Can an experienced Android game developper help me balance this out so we can move on to other parts of the game as I have no idea what the best way to create animations is.

• Where can you find your first customers as a freelancer?

  - by Adam Smith

  I want to start doing freelance work, but no matter how I look at it, it seems like the best way to get customers and to have work most of the time, you have to already be in the freelancing game. Most freelancers I've talked to have had the same customers over the years or got new customers because their satisfied clients referred them. What I'd like to know from the successful people here that work as freelancers is how do you start doing business when you haven't yet set foot in freelancing? I want to start small, creating websites that won't require me to hire other people other than maybe a designer I already know. (I'd like to create desktop applications as well, but I think I should keep that for later when I'm more experienced) . I thought about localized Google ads or visiting companies and meeting the people in charge there, but I wouldn't know which kind of businesses to look for or if it's even a good way to approach this. Anyone care to share their personal startup experiences / advice that can help future freelancers?

What type of things would you put in a personal Wiki?

• systems/software engineering design process

  - by adam kim

  I just developed my first non-trivial android app. It was a complete nightmare. I came up with an idea, build the app, changed my idea, and implemented a lot of input from others on new features. All in all my app took 10 times longer than I think that it should have, it is almost impossible to look the source code and tell what's going on with the classes, and may or may not have unused methods that I'll never be able to find... So I would like an opinion from those of you with experience on how to plan out my designs for the future. I created a flow chart (pencil drawn) of a plan: I would like constructive criticism.

• Maximized Office 2007 gets cut off on multi-monitor setup with different resolutions

  - by Adam M-W

  I've got an external monitor plugged into my laptop that I like to use for typing up documents, but I've noticed that when Word is maximized it gets cut off at where the primary monitor's bounds are. Is this a bug in Wine (i'm using version 1.3.32), or with my Window Manager (metacity with compositing enabled, version 2.34.1), with my graphics drivers (nouveau) or something else? I know that I can fix it by unmaximizing (it doesn't get cut off and I can resize to the entirety of the second monitor), but it keeps on maximizing itself as it (rightly so) knows that it should be taking up the entire screen. I don't really want to use the "Emulate a virtual desktop feature", I would prefer to find the source of this issue.

• Dependency injection: what belongs in the constructor?

  - by Adam Backstrom

  I'm evaluating my current PHP practices in an effort to write more testable code. Generally speaking, I'm fishing for opinions on what types of actions belong in the constructor. Should I limit things to dependency injection? If I do have some data to populate, should that happen via a factory rather than as constructor arguments? (Here, I'm thinking about my User class that takes a user ID and populates user data from the database during construction, which obviously needs to change in some way.) I've heard it said that "initialization" methods are bad, but I'm sure that depends on what exactly is being done during initialization. At the risk of getting too specific, I'll also piggyback a more detailed example onto my question. For a previous project, I built a FormField class (which handled field value setting, validation, and output as HTML) and a Model class to contain these fields and do a bit of magic to ease working with fields. FormField had some prebuilt subclasses, e.g. FormText (<input type="text">) and FormSelect (<select>). Model would be subclassed so that a specific implementation (say, a Widget) had its own fields, such as a name and date of manufacture: class Widget extends Model { public function __construct( $data = null ) { $this->name = new FormField('length=20&label=Name:'); $this->manufactured = new FormDate; parent::__construct( $data ); // set above fields using incoming array } } Now, this does violate some rules that I have read, such as "avoid new in the constructor," but to my eyes this does not seem untestable. These are properties of the object, not some black box data generator reading from an external source. Unit tests would progressively build up to any test of Widget-specific functionality, so I could be confident that the underlying FormFields were working correctly during the Widget test. In theory I could provide the Model with a FieldFactory() which could supply custom field objects, but I don't believe I would gain anything from this approach. Is this a poor assumption?

• "has no motion" warnings

  - by Adam R. Grey

  When I reimport my project's Library, I get lots of warnings such as State combat.Ghoul Attack has no motion but I have no idea why. In this specific case, I looked up Ghoul Attack. Here's the state in which it appears, in the only animator controller that includes anything called Ghoul Attack: State: m_ObjectHideFlags: 3 m_PrefabParentObject: {fileID: 0} m_PrefabInternal: {fileID: 0} m_Name: Ghoul Attack m_Speed: 1 m_CycleOffset: 0 m_Motions: - {fileID: 7400000, guid: 0db269712a91fd641b6dd5e0e4c6d507, type: 3} - {fileID: 0} m_ParentStateMachine: {fileID: 110708233} m_Position: {x: 492, y: 132, z: 0} m_IKOnFeet: 1 m_Mirror: 0 m_Tag: I thought perhaps that second one - {fileID: 0} was throwing up the warning incorrectly, so I removed it. There was no effect, I still get warnings about Ghoul Attack. So given that the only state I know of with that name does in fact have motion, what is this warning actually trying to tell me?

• Attaining credit card data

  - by Adam

  I've read the many posts on this site that say we are not allowed to store cc numbers if we are not pci-compliant. But, I'm wondering if it is possible to send a CC number through a form to an email address? Would that be still infringing on the standards? The reason I ask is that a local business owner wants to retrieve a number through a form on his website, so he can manually enter the cc info on his end. I'm assuming the only way to properly get a credit card number is to setup a merchant account? What's the best way to get a cc number without calling the actual customer? I'm thinking email is a bad idea as well.

• 2D Grid based game - how should I draw grid lines?

  - by Adam K Dean

  I'm playing around with a 2D grid based game idea, and I am using sprites for the grid cells. Let's say there is a 10 x 10 grid and each cell is 48x48, which will have sprites drawn there. That is fine. But in design mode, I'd like to have a grid overlay the screen. I can do this either with sprites (2x600 pixel image etc) or with primitives, but which is best? Should I really be switching between sprites and 3d/2d rendering? Like so: Thanks!

• Is there a better way to run ubuntu from usb disk

  - by Adam Butler

  I have an old laptop with a broken hard drive controller and am running the previous ubuntu from a usb. I installed this as per standard instructions by running some program that copied the live cd to the usb. This has had a few problems, it seems like it was just made for trying and not for everyday use. Ideally I would like to do a proper install to the usb disk instead of just running off the installer disk. Is there a way to do this? The main problems I have are: When adding mounts to fstab it gets overwritten on each reboot When installing updates the kernel cannot be updated

• How to embed an authorize.net payment gateway form into a single page website with one item for sale?

  My website sells one item. I am currently using the simple checkout button embedded on the website. Rather than having the button I would like the order form to be on the single page with a field for quantity. At first I imagined that there would be a simple form that I could embed however it looks like that I need a full integration into my website through the Advanced Integration Method (AIM) which is much more complicated then I wanted. I don't want integration into my website, can I do it without, and if I have to what is the cleanest and simplest way to do it?
