  • Edit 100MB+ file

    - by Majid Fouladpour
    I have captured some traffic with Wireshark and saved the result as a file. The file has 3 sections now: request headers response headers response body The response body is to become an flv file, but now everything is saved as a single file. So I need a way to delete the first two sections from the file, but the problem is that the file is very big (over a thousand mega bytes). I have tried to open it with gedit, but no matter how long I wait, gedit hangs and remains unresponsive until I kill it. What tool can I use to edit this big file easily?

  • SQL vs. Oracle Live Debate (AKA Smackdown!)

    - by Peter W. DeBetta
    A few years ago I was speaking at a conference in Raleigh, NC where Ted Neward and I found a fun way to promote a Java vs. .NET debate that was planned one evening. We stood in the middle of a crowd during one of the breaks and starting “arguing” about Java vs. .NET with one another. Our voice levels quickly raised and we ended it by slapping each other across the face with a glove to request a challenge. It was a great way to segue to our announcing of the actual debate planned later that evening....(read more)

  • Mouse and keyboard stop working after suspend or screensaver lock

    - by LEo
    If I leave the computer and let it run into screensaver and lock the screen, the mouse left click won't go back to work. If I suspend the computer, the keyboard won't get back to work. It started after upgrading to Ubuntu 11.04. Any tips to solve this problem? The follwing lines I got on dmesg after the problem happened [30536.564415] psmouse.c: TouchPad at isa0060/serio1/input0 lost sync at byte 1 [30536.565725] psmouse.c: TouchPad at isa0060/serio1/input0 lost sync at byte 1 [30536.568466] psmouse.c: TouchPad at isa0060/serio1/input0 lost sync at byte 1 [30536.569790] psmouse.c: TouchPad at isa0060/serio1/input0 lost sync at byte 1 [30536.571123] psmouse.c: TouchPad at isa0060/serio1/input0 lost sync at byte 1 [30536.571126] psmouse.c: issuing reconnect request and that after I tried to plug again my USB mouse: [31570.040088] usb 6-1: USB disconnect, address 2 [31573.490095] usb 6-1: new low speed USB device using uhci_hcd and address 3 [31573.687376] input: Microsoft Basic Optical Mouse as /devices/pci0000:00/0000:00:1d.1/usb6/6-1/6-1:1.0/input/input12 [31573.687544] generic-usb 0003:045E:0084.0002: input,hidraw0: USB HID v1.10 Mouse [Microsoft Basic Optical Mouse] on usb-0000:00:1d.1-1/input0

  • Collaboration platforms

    - by Thomas
    Are there any good collaboration platforms for game development? This would include the following features: Easy way to find various people you need to build games (programmer, artist etc) and forming a team like for example codeplex Online portfolio for users where they can offer their services (either paid or free) Posibility to create a game specific blog or site with social media integration to show the world what's being created Easy way to manage game content / resources with sufficient online storage, version control and if possible source control Manage all phases of game development (startup, creating concept, finding a team, creating proof of concept, production phase etc) and publish specific information for each phase also on social media etc. Manage asset creation flow (request for specific content like a sound, production of sound, uploading the sound, notification to the requester, implementation of the file, retouching in several cycles etc)

  • Graphic demonstrating emphasis of front end in web apps

    - by sohail
    I remember stumbling across an amusing graphic a year or so ago which demonstrated the tiers of web development. The back-end was shown as a tiny box, but the front end was shown as a huge box crammed with lots of front-end technologies like AJAX, DHTML. This is all a vague recollection. Does anyone know where on the Intraweb this graphic might be? It was probably on a programming cartoon site, but I only view XKCD on a regular basis, and I couldn't find it on there. Although tagged as fun, my request does have a productive edge to it - it would be quite useful in driving home to my colleagues how UI top-heavy web application development has become.

  • How do Expires headers and cache manifest rules work together?

    - by Robert K
    I find the W3C's official Offline Web Applications specification to be rather vague about how the cache manifest interacts with headers such as ETag, Expires, or Pragma on cached assets. I know that the manifest should be checked with each request so that the browser knows when to check the other assets for updates. But because the specification doesn't define how the cache manifest interacts with normal cache instructions, I can't predict precisely how the browser will react. Will assets with a future expiration date be refreshed (no matter the cache headers) when the cache manifest is updated? Or, will those assets obey the normal caching rules? Which caching mechanism, HTTP cache versus cache manifest, will take precedence, and when?

  • Do PHP-FPM (and other PHP handlers) need execute permissions on the PHP files they're serving?

    - by Andrew Cheong
    I read in a post at Server Fault that PHP-FPM needs execute permissions. However, the answer in When creating a website, what permissions and directory structure? only grants read and write permissions to PHP-FPM. Maybe I don't quite understand how PHP handlers (or CGI in general) work, but the two claims seem contradictory to me. As I understand, when Apache / Nginx gets a request for foobar.php, it "passes" the file to an appropriate handler. That is, I imagine it's as if www-root (or apache or whomever the webserver's running as) were to run some command, /usr/sbin/php-fpm foobar.php Actually, no, that's naive, I just realized. PHP-FPM must be a running instance (if it's to be performant, and cache, etc.), so probably PHP-FPM is just being told, "Hey, quick, process this file for me!" In either case, I don't see why execute permissions are necessary. It's not like the webserver needs to literally execute the file, i.e. ./foobar.php Is the Server Fault answer simply mistaken?

  • How do you unit test your javascript

    - by Erin
    I spend a lot of time working in javascript of late. I have not found a way that seems to work well for testing javascript. This in the past hasn't been a problem for me since most of the websites I worked on had very little javascript in them. I now have a new website that makes extensive use of jQuery I would like to build unit tests for most of the system. My problems are this. Most of the functions make changes to the DOM in some way. Most of the functions request data from the web server as well and require a session on the service to get results back. I would like to run the test from either a command line or a test running harness rather then in a browser. Any help or articles I should be reading would be helpful.

  • it is a good approach to implement dependency injection in a desktop app?

    - by luis_laurent
    Well, the thing is that I am just about to create a Desktop App (with .NET windows forms) And now I just wonder if it would be really a wise choise to use any IoC (StructureMap,Ninject,Spring .Net), I have used them before for Asp.Net web applications but what makes me doubt now is the fact that working with windows forms my business entities will persist when I navigate through tabs and unlike than web forms or mvc apps where it would be necesary to inject my business entity for every new request that is performed, I mean this because of the Asp.Net page life cycle where is performed the initialization and controls instantiation. Maybe I am misunderstanding the point of using an IoC, so please tell me what do you think would be a better choise?

  • SEO: disallowing Google from indexing forms in iframes or not?

    - by Marco Demaio
    I usually place forms in iframes (i.e. order form, request assistance form, contact forms, ect.). Just the forms, I never place other contents or pages in iframes. From a SEO point of view, would you exclude forms from being indexed/crawled by Google or not? I mean my forms hardly ever contains keyword/keyphrases, moreover I obviously place empty title/meta description tags in pages shown in iframe to display forms, cause those titles are never displaied in browser title bar. So I'm wondering what's the point of letting Google index them? Moreover I think these form pages might suck out PR from all other pages that are more valuable for SEO. If your answer is "yes I would exclude them form indexing" would you simply use robots.txt to exclude them? Thanks!

  • How do I implement layers on a tile map?

    - by mitch
    I have a game where, based upon the visible tiles in the viewport, I need to retrieve data of items in the visible tiles. I am planning to use Javascript to AJAX request in a batch based upon the visible tiles which contain image tags like Google Maps. The layer will be in SVG or canvas. The item information will be in JSON format. What is the best approach, to fetch the data? I currently have complex class I wrote in Javascript which determines the visible columns/rows and offsets relative to the visible area shown. Each item is also user contributed and will be rendered in canvas or SVG layer.

  • Google Maps API: Premier License or excess map loads?

    - by j0nes
    I am currently looking for a way on how to deal with the Google Maps API usage limits. I am planning a redesign of our page that will probably get around 2 million map loads per month. This will surely break the usage limit of 750000 map loads per month available in the free version. If we pay for excess map loads, this means we would have to pay 5000$ per month. The other option would be to use a Premier license, however there is very few information available on the usage limits for this and the price. I have filled the request form to get a custom offer from Google, but I did not get any response yet. Can anyone of the Premier license holders tell me which option will be cheaper for my usage pattern, paying for Premier license or paying for excess map loads?

  • Is MVC now the only way to write PHP?

    - by JasonS
    Hey... its XMAS Eve and something is bugging me... yes, I have work on my mind even when I am on holiday. The vast amount of frameworks available for PHP now use MVC. Even ASP.net has its own MVC module. I can see the attraction of MVC, I really can and I use it frequently. The only downside that I can see is that you have to fire up the whole system to execute a page request. Depending on your task this can be a little wasteful. So the question. In a professional environment is this the only way to use PHP nowadays or are their other design methods which have alternative benefits?

  • High level overview of Visual Studio Extensibility APIs

    - by Daniel Cazzulino
    If your head is dizzy with the myriad VS services and APIs, from EnvDTE to Shell.Interop, this should clarify a couple things. First a bit of background: APIs on EnvDTE (DTE for short, since that’s the entry point service you request from the environment) was originally an API intended to be used by macros. It’s also called the automation API. Most of the time, this is a simplified API that is easier to work with, but which doesn’t expose 100% of what VS is capable of doing. It’s also kind of the “rookie” way of doing VS extensibility (VSX for short), since most hardcore VSX devs sooner or later realize that they need to make the leap to the “serious” APIs. The “real” VSX APIs virtually always start with IVs, make heavy use of uint, ref/out parameters and HResults. These are the APIs that have been evolving for years and years, and there is a lot of COM baggage. ...Read full article

  • "Invalid operation" status code in a HATEOAS REST API

    - by FinnNk
    In a HATEOAS API links are returned which represent possible state transitions. A conforming client should just be retrieving and following those links, but if a non-conforming client is constructing URIs rather than following the supplied links what would be the most appropriate status code/response to return? 400 would work, together with some information in the response body - this is what we're currently doing 403 I guess would be wrong, as it implies that the request could never work - but potentially the link may be available in the future 404 sounds plausible - at this point in time the resource doesn't exist What do people think? I know that conditional requests can handle requests based on stale responses (resulting in e.g. 412s), but this is a slightly different situation.

  • Application Composer: Exposing Your Customizations in BI Analytics and Reporting

    - by Richard Bingham
    Introduction This article explains in simple terms how to ensure the customizations and extensions you have made to your Fusion Applications are available for use in reporting and analytics. It also includes four embedded demo videos from our YouTube channel (if they don't appear check the browser address bar for a blocking shield icon). If you are new to Business Intelligence consider first reviewing our getting started article, and you can read more about the topic of custom subject areas in the documentation book Extending Sales. There are essentially four sections to this post. First we look at how custom fields added to standard objects are made available for reporting. Secondly we look at creating custom subject areas on the standard objects. Next we consider reporting on custom objects, starting with simple standalone objects, then child custom objects, and finally custom objects with relationships. Finally this article reviews how flexfields are exposed for reporting. Whilst this article applies to both Cloud/SaaS and on-premises deployments, if you are an on-premises developer then you can also use the BI Administration Tool to customize your BI metadata repository (the RPD) and create new subject areas. Whilst this is not covered here you can read more in Chapter 8 of the Extensibility Guide for Developers. Custom Fields on Standard Objects If you add a custom field to your standard object then it's likely you'll want to include it in your reports. This is very simple, since all new fields are instantly available in the "[objectName] Extension" folder in existing subject areas. The following two minute video demonstrates this. Custom Subject Areas for Standard Objects You can create your own subject areas for use in analytics and reporting via Application Composer. An example use-case could be to simplify the seeded subject areas, since they sometimes contain complex data fields and internal values that could confuse business users. One thing to note is that you cannot create subject areas in a sandbox, as it is not supported by BI, so once your custom object is tested and complete you'll need to publish the sandbox before moving forwards. The subject area creation processes is essentially two-fold. Once the request is submitted the ADF artifacts are generated, then secondly the related metadata is sent to the BI presentation server API's to make the updates there. One thing to note is that this second step may take up to ten minutes to complete. Once finished the status of the custom subject area request should show as 'OK' and it is then ready for use. Within the creation processes wizard-like steps there are three concepts worth highlighting: Date Flattening - this feature permits the roll up of reports at various date levels, such as data by week, month, quarter, or year. You simply check the box to enable it for that date field. Measures - these are your own functions that you can build into the custom subject area. They are related to the field data type and include min-max for dates, and sum(), avg(), and count() for  numeric fields. Implicit Facts - used to make the BI metadata join between your object fields and the calculated measure fields. The advice is to choose the most frequently used measure to ensure consistency. This video shows a simple example, where a simplified subject area is created for the customer 'Contact' standard object, picking just a few fields upon which users can then create reports. Custom Objects Custom subject areas support three types of custom objects. First is a simple standalone custom object and for which the same process mentioned above applies. The next is a custom child object created on a standard object parent, and finally a custom object that is related to a parent object - usually through a dynamic choice list. Whilst the steps in each of these last two are mostly the same, there are differences in the way you choose the objects and their fields. This is illustrated in the videos below.The first video shows the process for creating a custom subject area for a simple standalone custom object. This second video demonstrates how to create custom subject areas for custom objects that are of parent:child type, as well as those those with dynamic-choice-list relationships. &lt;span id=&quot;XinhaEditingPostion&quot;&gt;&lt;/span&gt; Flexfields Dynamic and Extensible Flexfields satisfy a similar requirement as custom fields (for Application Composer), with flexfields common across the Fusion Financials, Supply Chain and Procurement, and HCM applications. The basic principle is when you enable and configure your flexfields, in the edit page under each segment region (for both global and context segments) there is a BI Enabled check box. Once this is checked and you've completed your configuration, you run the Scheduled Process job named 'Import Oracle Fusion Data Extensions for Transactional Business Intelligence' to generate and migrate the related BI artifacts and data. This applies for dynamic, key, and extensible flexfields. Of course there is more to consider in terms of how you wish your flexfields to be implemented and exposed in your reports, and details are given in Chapter 4 of the Extending Applications guide.

  • The Best BPM Journey: More Exciting Destinations with Process Accelerators

It was interesting to hear definite patterns emerging from those conversations: “BPM is a journey”, “experiences to share”, “our organization now understands what BPM is”, and my favorite (with some caveats): “BPM is like wine tasting, once you start, you want to try more”. These customers have started their journey, climbed up the learning curve, and reached a vantage point that allows them to see their next BPM destination. They see the next few processes they are going to tackle and improve with BPM. These processes/destinations target both horizontal processes where BPM replaces or coordinates manual activities, and critical industry processes that the company needs to improve to compete and deliver increasing value. Each new destination generates value, allowing the organization to reduce the cost of manual processes that were not supported by apps/custom development, and increase efficiency of end-to-end processes partially covered by apps/custom dev. The question we wanted to answer is how to help organizations experience deeper success with BPM, by increasing their awareness of the potential for reaching new targets, and equipping them with the right tools. We decided that we needed to identify destinations, and plot routes to show the fastest path to those destinations. In the end we want to enable customers to reach “Process Excellence”: continuously set new targets and consistently and efficiently reach them. The result is Oracle Process Accelerators (PA), solutions built using the rich functionality in Oracle BPM Suite. PAs offers a rapidly expanding list of exciting destinations. Our launch of the latest installment of Process Accelerators at Oracle Open World includes new Industry-focused solutions such as Public Sector Incident Reporting and Financial Services Loan Origination, and improved other horizontal PAs, including Travel Request Management, Document Routing and Approval, and Internal Service Requests. Just before OOW we had extended the Oracle deployment of Travel Request Management, riding the enthusiastic response from early adopters among travelers (employees), management and support (approvers). “Getting there first” means being among the first to extract value from the PA approach, while acquiring deeper insights into the customers’ perspective. This is especially noteworthy when it comes to PAs, a set of solutions designed to be quickly deployed and iteratively improved by customers. The OOW launch has generated immediate feedback from customers, non-customers, analysts, and partners. They all confirmed that both Business and IT at organizations benefit from PAs when it comes to exploring the potential for BPM to improve their business processes. PAs help customers visualize what can be done with BPM, and PAs are made to be extended: you can see your destination, change the path to fit your needs, and deploy. We're discovering new destinations/processes that the market wants us to support, generic enough across industries and within industries. We'll keep on building sets of requirements, deliver functional design, construct solutions using Oracle BPM, and test them not only functionally but for performance, scalability, clustering, making them robust, product-quality. Delivering BPM solutions with product-grade quality is the equivalent of following a tried-and-tested path on a map. Do you know of existing destinations in your industry? If yes, we can draw a path to innovative processes together.

  • WMemoryProfiler is Released

    - by Alois Kraus
    What is it? WMemoryProfiler is a managed profiling Api to aid integration testing. This free library can get managed heap statistics and memory usage for your own process (remember testing) and other processes as well. The best thing is that it does work from .NET 2.0 up to .NET 4.5 in x86 and x64. To make it more interesting it can attach to any running .NET process. The reason why I do mention this is that commercial profilers do support this functionality only for their professional editions. An normally only since .NET 4.0 since the profiling API only since then does support attaching to a running process. This thing does differ in many aspects from “normal” profilers because while profiling yourself you can get all objects from all managed heaps back as an object array. If you ever wanted to change the state of an object which does only exist a method local in another thread you can get your hands on it now … Enough theory. Show me some code /// <summary> /// Show feature to not only get statisics out of a process but also the newly allocated /// instances since the last call to MarkCurrentObjects. /// GetNewObjects does return the newly allocated objects as object array /// </summary> static void InstanceTracking() { using (var dumper = new MemoryDumper()) // if you have problems use to see the debugger windows true,true)) { dumper.MarkCurrentObjects(); Allocate(); ILookup<Type, object> newObjects = dumper.GetNewObjects() .ToLookup( x => x.GetType() ); Console.WriteLine("New Strings:"); foreach (var newStr in newObjects[typeof(string)] ) { Console.WriteLine("Str: {0}", newStr); } } } … New Strings: Str: qqd Str: String data: Str: String data: 0 Str: String data: 1 … This is really hot stuff. Not only you can get heap statistics but you can directly examine the new objects and make queries upon them. When I do find more time I can reconstruct the object root graph from it from my own process. It this cool or what? You can also peek into the Finalization Queue to check if you did accidentally forget to dispose a whole bunch of objects … /// <summary> /// .NET 4.0 or above only. Get all finalizable objects which are ready for finalization and have no other object roots anymore. /// </summary> static void NotYetFinalizedObjects() { using (var dumper = new MemoryDumper()) { object[] finalizable = dumper.GetObjectsReadyForFinalization(); Console.WriteLine("Currently {0} objects of types {1} are ready for finalization. Consider disposing them before.", finalizable.Length, String.Join(",", finalizable.ToLookup( x=> x.GetType() ) .Select( x=> x.Key.Name)) ); } } How does it work? The W of WMemoryProfiler is a good hint. It does employ Windbg and SOS dll to do the heavy lifting and concentrates on an easy to use Api which does hide completely Windbg. If you do not want to see Windbg you will never see it. In my experience the most complex thing is actually to download Windbg from the Windows 8 Stanalone SDK. This is described in the Readme and the exception you are greeted with if it is missing in much greater detail. So I will not go into this here.   What Next? Depending on the feedback I do get I can imagine some features which might be useful as well Calculate first order GC Roots from the actual object graph Identify global statics in Types in object graph Support read out of finalization queue of .NET 2.0 as well. Support Memory Dump analysis (again a feature only supported by commercial profilers in their professional editions if it is supported at all) Deserialize objects from a memory dump into a live process back (this would need some more investigation but it is doable) The last item needs some explanation. Why on earth would you want to do that? The basic idea is to store in your live process some logging/tracing data which can become quite big but since it is never written to it is very fast to generate. When your process crashes with a memory dump you could transfer this data structure back into a live viewer which can then nicely display your program state at the point it did crash. This is an advanced trouble shooting technique I have not seen anywhere yet but it could be quite useful. You can have here a look at the current feature list of WMemoryProfiler with some examples.   How To Get Started? First I would download the released source package (it is tiny). And compile the complete project. Then you can compile the Example project (it has this name) and uncomment in the main method the scenario you want to check out. If you are greeted with an exception it is time to install the Windows 8 Standalone SDK which is described in great detail in the exception text. Thats it for the first round. I have seen something more limited in the Java world some years ago (now I cannot find the link anymore) but anyway. Now we have something much better.

  • Instantiate proper class based on some input

    - by Adam Backstrom
    I'm attempting to understand how "switch as a code smell" applies when the proper code path is determined by some observable piece of data. My Webapp object sets an internal "host" object based on the hostname of the current request. Each Host subclass corresponds to one possible hostname and application configuration: WwwHost, ApiHost, etc. What is an OOP way for a host subclass to accept responsibility for a specific hostname, and for Webapp to get an instance of the appropriate subclass? Currently, the hostname check and Host instantiation exists within the Webapp object. I could move the test into a static method within the Host subclasses, but I would still need to explicitly list those subclasses in Webapp unless I restructure further. It seems like any solution will require new subclasses to be added to some centralized list.
