  • Subterranean IL: Volatile

    - by Simon Cooper
    This time, we'll be having a look at the volatile. prefix instruction, and one of the differences between volatile in IL and C#. The volatile. prefix volatile is a tricky one, as there's varying levels of documentation on it. From what I can see, it has two effects: It prevents caching of the load or store value; rather than reading or writing to a cached version of the memory location (say, the processor register or cache), it forces the value to be loaded or stored at the 'actual' memory location, so it is then immediately visible to other threads. It forces a memory barrier at the prefixed instruction. This ensures instructions don't get re-ordered around the volatile instruction. This is slightly more complicated than it first seems, and only seems to matter on certain architectures. For more details, Joe Duffy has a blog post going into the details. For this post, I'll be concentrating on the first aspect of volatile. Caching field accesses To demonstrate this, I created a simple multithreaded IL program. It boils down to the following code: .class public Holder { .field public static class Holder holder .field public bool stop .method public static specialname void .cctor() { newobj instance void Holder::.ctor() stsfld class Holder Holder::holder ret }}.method private static void Main() { .entrypoint // Thread t = new Thread(new ThreadStart(DoWork)) // t.Start() // Thread.Sleep(2000) // Console.WriteLine("Stopping thread...") ldsfld class Holder Holder::holder ldc.i4.1 stfld bool Holder::stop call instance void [mscorlib]System.Threading.Thread::Join() ret}.method private static void DoWork() { ldsfld class Holder Holder::holder // while (!Holder.holder.stop) {} DoWork: dup ldfld bool Holder::stop brfalse DoWork pop ret} If you compile and run this code, you'll find that the call to Thread.Join() never returns - the DoWork spinlock is reading a cached version of Holder.stop, which is never being updated with the new value set by the Main method. Adding volatile to the ldfld fixes this: dupvolatile.ldfld bool Holder::stopbrfalse DoWork The volatile ldfld forces the field access to read direct from heap memory, which is then updated by the main thread, rather than using a cached copy. volatile in C# This highlights one of the differences between IL and C#. In IL, volatile only applies to the prefixed instruction, whereas in C#, volatile is specified on a field to indicate that all accesses to that field should be volatile (interestingly, there's no mention of the 'no caching' aspect of volatile in the C# spec; it only focuses on the memory barrier aspect). Furthermore, this information needs to be stored within the assembly somehow, as such a field might be accessed directly from outside the assembly, but there's no concept of a 'volatile field' in IL! How this information is stored with the field will be the subject of my next post.

  • drda protocol specs

    - by Alon Rew
    When connecting to a server using the DRDA protocol, is it true that the first Client-To-Server command MUST be EXCSAT chained with ACCSEC? I found 2 different answers when I googled it. If you look at The Open Group web site (https://collaboration.opengroup.org/dbiop/) it can be understood that the answer is NO. However, if you look at the IBM website (http://publib.boulder.ibm.com/infocenter/dzichelp/v2r2/index.jsp?topic=%2Fcom.ibm.ims11.doc.apr%2Fims_ddm_excsat.htm) you can understand the answer is YES. So which is it?

  • Controlling text that appears in google search results

    - by Mick
    I have recently made a simple (pure HTML) website. The most important key phrase that I want to capture is "full reserve banking". Currently, if I type "full reserve banking" (without quotes) into google, then my site appears as the 7th item on the first page. I am reasonably happy with this as the site is so new. But one frustration is that the text that google displays in relation to my site is rather misleading. The main message I would like to get across is that my site is "A collection of resources for anyone interested in this alternative monetary system." and I have this as the first line of text on the page. Unfortunately, this important sentence is nowhere to be seen in the google search result. So my question is - is there anything I can do to fix this error? Edit: I noticed that someone edited this question to remove the name of the website. I was very keen to leave it in because being able to look at it makes it far easier to diagnose what I did wrong. Indeed the answer suggested by "Su" clearly shows that they looked at my website and analyzed what it was doing which helped them give a clearer answer. If I am breaking some policy by including the name then please explain what this policy is in a comment. Edit: I have now made a series of changes to my meta descriptions as inspired by the answers given here. On the homepage I now have the text: <META NAME="description" CONTENT="A collection of resources for anyone interested in Full Reserve Banking. What it is, how it works, web resources, organisations, research papers etc."> I am now very excited to see what will happen after the next visit by the google robots. Edit: Result! I just did a google search for "full reserve banking", and the text that appeared was: Full Reserve Banking: The definitive resource. A collection of resources for anyone interested in Full Reserve Banking. What it is, how it works, web resources, organisations, research papers etc. www.fullreservebanking.com/ - Cached By the way, I did originally have a meta description - but it was too short, it just said "full reserve banking". Google obviously assumed this was too little and so chose to use its own algorithms to cook up a different sentence from the main text.

  • Android Touch Event Collision Detection

    - by chrissb
    I'm relatively new to both Java and Android, so hopefully the problem I'm having is stemming from something pretty minor that I've overlooked. I've got a (very early stage) game that I've started working on, for Android using Java. At this stage, when the user touches the screen, if they touched a point at which there is an enemy, the enemies health is decreased and they become immobile (for the current implementation at least). The issue that I'm having is that the touch detection doesn't always seem to work. I've got a testing sprite set up that goes to the eventX and eventY coordinates of the touch down event, and it always seems to collide with the enemy object. Yet, the enemy doesn't always register as being hit, and sometimes a hit is registered when the sprite indicates the touch coordinates were outside of the enemies bounding box. I realise that this probably doesn't mean much without any code, so here's what I've got so far. Be gentle, as this is literally my first attempt at something more than basic movement etc. First off, the MainGamePanel class registers the touch event, and informs the levelmanager class (which is what I set up to monitor/handle enemies) public boolean onTouchEvent(MotionEvent event) { if (event.getAction() == MotionEvent.ACTION_DOWN){ levelManager.handleActionDown((int)event.getX(), (int)event.getY()); targetX=event.getX(); targetY=event.getY(); } if (event.getAction() == MotionEvent.ACTION_MOVE) { //the gestures } if (event.getAction() == MotionEvent.ACTION_UP) { //touch was released } return true; } From there, in the levelmanager class the touch event is passed on to all of the enemies within a list array: public static void handleActionDown(int eventX,int eventY){ hit=false; for (enemy1 en : enemy1array){ en.handleActionDown(eventX, eventY); } } The rest of the collision code is handled within the enemies handleActionDown function: public void handleActionDown(int eventX, int eventY) { if(eventX>this.x-enemy1bitmap.getWidth() && eventX<this.x+enemy1bitmap.getWidth() && eventY>this.y-enemy1bitmap.getHeight() && eventY<this.x+enemy1bitmap.getHeight()){ takeDamage(1); levelmanager.setHit(); } } I should probably be using getWidth()/2 and getHeight()/2 for it to be more accurate, but I expanded the area to test this - although I've noticed no improvement. At this stage, the games detection over whether or not the enemy is hit is spotty at best. Generally it takes two or three attempts before a collision is successfully registered, even though the sprite that is being used for testing and set to the eventX and eventY coordinates always indicates that the collision should have worked. Hopefully someone can steer me in the right direction here, and if more information is needed, ask away! Cheers, -Chris

  • what tool should I use for drawing 2d OpenGL shapes?

    - by Kenny Winker
    I'm working on a very simple OpenGL ES 2.0 game, and I'm not sure what tool to use to create the vertex data I need. My first thought was adobe illustrator, but I can't seem to google up any info on how to convert an .ai file to vertices. I'm only going to be using very simple 2d shapes so I wonder if I need to use a 3d modelling program? How is this typically done, when you are working with 2d non-sprite shapes?

  • Creating a Strong Bridge to the Post PC World

    - by Webgui
    Moving from location to location requires strong roads.  When crossing a barrier though, like a body of water or valley, we are required to build a strong bridge to get us from point A to point B in a way that is fast, safe, and easy.Yet we are not talking here about driving a car or riding a bus.  As we in the computing world are evidencing the move to the post-PC era, modernizing and migrating legacy applications to harness the power of HTML5 web, cloud and mobile is one of the most difficult challenges enterprises have faced.  Constant technological changes have weakened the business value of legacy systems, which have been developed over the years through huge investments.  There are several risks of course in this move.  Do you choose to simply rewrite code of legacy apps and transform them to HTML5 one by one?  This is quite expensive (according to research firm Gartner, the cost is $6 - $26 per line of code).  Of course, the pace of the rewriting process is very slow – around 170 lines per day for each developer – which slows down business productivity in a world in which no organization can afford to fall behind.  Other questions include whether the new cloud-based apps will have the same functionality as the trusted applications that worked for you for years.  How will the user experience be affected?  And of course, what about data security?  So we are faced with the challenge of building a sturdy bridge to stabilize our move in order to allow us to confidently and easily move our legacy applications into the post-PC era.   We at Gizmox are excited to release the first downloadable Community Technology Preview (CTP) of our Instant CloudMove Transposition Studio.Developers: To download the tool, and try it out for yourself, please visit http://www.visualwebgui.com/download.aspx.The CTP is the first and only tool-based solution allowing any Microsoft Visual Studio developer to extend VB6 and .NET enterprise client/server applications into HTML5 web, cloud and mobile applications, including the ability to upgrade their code and UI while doing so.   It is the only solution to fully replicate enterprise desktop applications behavior in the post-PC era.  With Instant CloudMove, the transposed application is available on any mobile or tablet device, browser and across any client operating system. Moreover, the extended application logic and data remains on the server behind the fire-wall and therefore the application’s front end is secured-by-design.   We would love for you to try out the tool for yourselves and let us know what you think.  How are you finding the move?

  • Virtual Lab part 2&ndash;Templates, Patterns, Baselines

    - by Geoff N. Hiten
    Once you have a good virtualization platform chosen, whether it is a desktop, server or laptop environment, the temptation is to build “X”.  “X” may be a SharePoint lab, a Virtual Cluster, an AD test environment or some other cool project that you really need RIGHT NOW.  That would be doing it wrong. My grandfather taught woodworking and cabinetmaking for twenty-seven years at a trade school in Alabama.  He was the first instructor hired at that school and the only teacher for the first two years.  His students built tables, chairs, and workbenches so the school could start its HVAC courses.   Visiting as a child, I also noticed many extra “helper” stands, benches, holders, and gadgets all built from wood.  What does that have to do with a virtual lab, you ask?  Well, that is the same approach you should take.  Build stuff that you will use.  Not for solving a particular problem, but to let the Virtual Lab be part of your normal troubleshooting toolkit. Start with basic copies of various Operating Systems.  Load and patch server and desktop OS environments.  This also helps build your collection of ISO files, another essential element of a virtual Lab.  Once you have these “baseline” images, you can use your Virtualization software’s snapshot capability to freeze the image.  Clone the snapshot and you have a brand new fully patched machine in mere moments.  You may have to sysprep some of the Microsoft OS environments if you are going to create a domain environment or experiment with clustering.  That is still much faster than loading and patching from scratch. So once you have a stock of raw materials (baseline images in this case) where should you start.  Again, my grandfather’s workshop gives us the answer.  In the shop it was workbenches and tables to hold large workpieces that made the equipment more useful.  In a Windows environment the same role falls to the fundamental network services:  DHCP, DNS, Active Directory, Routing, File Services, and Storage services.  Plan your internal network setup.  Build out an AD controller with all the features listed.  Make the actual domain an isolated domain so it will not care about where you take it.  Add the Microsoft iSCSI target.  Once you have this single system, you can leverage it for almost any network environment beyond a simple stand-alone system. Having these templates and fundamental infrastructure elements ready to run means I can build a quick lab in minutes instead of hours.  My solutions are well-tested, my processes fully documented with screenshots, and my plans validated well before I have to make any changes to client systems.  the work I put in is easily returned in increased value and client satisfaction.

  • Stop Saying "Multi-Channel!"

    - by David Dorf
    I keep hearing the term "multi-channel" in our industry, but its time to move on. It kinda reminds me of the term "ECR" or electronic cash register. Long ago ECR was a leading-edge term, but nowadays its rarely used because its table-stakes. After all, what cash register today isn't electronic? The same logic applies to multi-channel, at least when we're talking about tier-1 and tier-2 retailers. If you're still talking about multi-channel retailing, you're in big trouble. Some have switched over to the term "cross-channel," and that's a step in the right direction but still falls short. Its kinda like saying, "I upgraded my ECR to accept debit cards!" Yawn. Who hasn't? Today's retailers need to focus on omni-channel, which I first heard from my friends over at RSR but was originally coined at IDC. First retailers added e-commerce to their store and catalog channels yielding multi-channel retailing. Consumers could use the channel that worked best for them. Then some consumers wanted to combine channels with features like buy-on-the-Web, pickup-in-the-store. Thus began the cross-channel initiatives to breakdown the silos and enable the channels to communicate with each other. But the multi-channel architecture is full of duplication that thwarts efforts of providing a consistent experience. Each has its own cart, its own pricing, and often its own CRM. This was an outcrop of trying to bring the independent channels to market quickly. Rather than reusing and rebuilding existing components to meet the new demands, silos were created that continue to exist today. Today's consumers want omni-channel retailing. They want to interact with brands in a consistent manner that is channel transparent, yet optimized for that particular interaction. The diagram below, from the soon-to-be-released NRF Mobile Blueprint v2, shows this progression. 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. I'm looking forward to the day in which I can use my phone to scan QR-codes in a catalog to create a shopping cart of items. Then do some further research on the retailer's Web site and be told about related items that might interest me. Be able to easily solicit opinions and reviews from social sites, and finally enter the store to pickup my items, knowing that any applicable coupons have been applied. In this scenario, I the consumer are dealing with a single brand that is aware of me and my needs throughout the entire transaction. Nirvana.

  • SceneManagers as systems in entity system or as a core class used by a system?

    - by Hatoru Hansou
    It seems entity systems are really popular here. Links posted by other users convinced me of the power of such system and I decided to try it. (Well, that and my original code getting messy) In my project, I originally had a SceneManager class that maintained needed logic and structures to organize the scene (QuadTree, 2D game). Before rendering I call selectRect() and pass the x,y of the camera and the width and height of the screen and then obtain a minimized list containing only visible entities ordered from back to front. Now with Systems, originally in my first attempt my Render system required to get added all entities it should handle. This may sound like the correct approach but I realized this was not efficient. Trying to optimize It I reused the SceneManager class internally in the Renderer system, but then I realized I needed methods such as selectRect() in others systems too (AI principally) and make the SceneManager accessible globally again. Currently I converted SceneManager to a system, and ended up with the following interface (only relevant methods): /// Base system interface class System { public: virtual void tick (double delta_time) = 0; // (methods to add and remove entities) }; typedef std::vector<Entity*> EntitiesVector; /// Specialized system interface to allow query the scene class SceneManager: public System { public: virtual EntitiesVector& cull () = 0; /// Sets the entity to be used as the camera and replaces previous ones. virtual void setCamera (Entity* entity) = 0; }; class SceneRenderer // Not a system { vitual void render (EntitiesVector& entities) = 0; }; Also I could not guess how to convert renderers to systems. My game separates logic updates from screen updates, my main class have a tick() method and a render() method that may not be called the same times. In my first attempt renderers were systems but they was saved in a separated manager, updated only in render() and not in tick() like all other systems. I realized that was silly and simply created a SceneRenderer interface and give up about converting them to systems, but that may be for another question. Then... something does not feel right, isn't it? If I understood correctly a system should not depend on another or even count with another system exposing an specific interface. Each system should care only about its entities, or nodes (as optimization, so they have direct references to relevant components without having to constantly call the component() or getComponent() method of the entity).

  • How to enable multiple displays with Catalyst drivers in Ubuntu 13.04?

    - by Lokitez
    First, I installed Ubuntu 13.04. I have an ATI Radeon HD 7850. The open source drivers allowed multiple displays, but were horrendously laggy (even opening a browser window took several seconds). When I installed the Catalyst proprietary drivers, performance was perfect. The only problem is that trying to enable dual-monitors in the Catalyst center was grayed out and in the Ubuntu settings resulted in the resolution error. Is there any way around this?

  • String contains trailing zeroes when converted from decimal [migrated]

    - by Locke
    I've run into an unusual quirk in a program I'm writing, and I was trying to figure out if anyone knew the cause. Note that fixing the issue is easy enough. I just can't figure out why it is happening in the first place. I have a WinForms program written in VB.NET that is displaying a subset of data. It contains a few labels that show numeric values (the .Text property of the labels are being assigned directly from the Decimal values). These numbers are being returned by a DLL I wrote in C#. The DLL calls a webservice which initially returns the values in question. It returns one as a string, the other as a decimal (I don't have any control over the webservice, I just consume it). The DLL assigns these to properties on an object (both of which are decimals) then returns that object back to the WinForm program that called the DLL. Obviously, there's a lot of other data being consumed from the webservice, but no other operations are happening which could modify these properties. So, the short version is: WinForm requests a new Foo from the DLL. DLL creates object Foo. DLL calls webservice, which returns SomeOtherFoo. //Both Foo.Bar1 and Foo.Bar2 are decimals Foo.Bar1 = decimal.Parse(SomeOtherFoo.Bar1); //SomeOtherFoo.Bar1 is a string equal to "2.9000" Foo.Bar2 = SomeOtherFoo.Bar2; //SomeOtherFoo.Bar2 is a decimal equal to 2.9D DLL returns Foo to WinForm. WinForm.lblMockLabelName1.Text = Foo.Bar1 //Inspecting Foo.Bar1 indicates my value is 2.9D WinForm.lblMockLabelName2.Text = Foo.Bar2 //Inspecting Foo.Bar2 also indicates I'm 2.9D So, what's the quirk? WinForm.lblMockLabelName1.Text displays as "2.9000", whereas WinForm.lblMockLabelname2.Text displays as "2.9". Now, everything I know about C# and VB indicates that the format of the string which was initially parsed into the decimal should have no bearing on the outcome of a later decimal.ToString() operation called on the same decimal. I would expect that decimal.Parse(someDecimalString).ToString() would return the string without any trailing zeroes. Everything I find online seems to corroborate this (there are countless Stack Overflow questions asking exactly the opposite...how to keep the formatting from the initial parsing). At the moment, I've just removed the trailing zeroes from the initial string that gets parsed, which has hidden the quirk. However, I'd love to know why it happens in the first place.

  • Augmenting your Social Efforts via Data as a Service (DaaS)

    - by Mike Stiles
    The following is the 3rd in a series of posts on the value of leveraging social data across your enterprise by Oracle VP Product Development Don Springer and Oracle Cloud Data and Insight Service Sr. Director Product Management Niraj Deo. In this post, we will discuss the approach and value of integrating additional “public” data via a cloud-based Data-as-as-Service platform (or DaaS) to augment your Socially Enabled Big Data Analytics and CX Management. Let’s assume you have a functional Social-CRM platform in place. You are now successfully and continuously listening and learning from your customers and key constituents in Social Media, you are identifying relevant posts and following up with direct engagement where warranted (both 1:1, 1:community, 1:all), and you are starting to integrate signals for communication into your appropriate Customer Experience (CX) Management systems as well as insights for analysis in your business intelligence application. What is the next step? Augmenting Social Data with other Public Data for More Advanced Analytics When we say advanced analytics, we are talking about understanding causality and correlation from a wide variety, volume and velocity of data to Key Performance Indicators (KPI) to achieve and optimize business value. And in some cases, to predict future performance to make appropriate course corrections and change the outcome to your advantage while you can. The data to acquire, process and analyze this is very nuanced: It can vary across structured, semi-structured, and unstructured data It can span across content, profile, and communities of profiles data It is increasingly public, curated and user generated The key is not just getting the data, but making it value-added data and using it to help discover the insights to connect to and improve your KPIs. As we spend time working with our larger customers on advanced analytics, we have seen a need arise for more business applications to have the ability to ingest and use “quality” curated, social, transactional reference data and corresponding insights. The challenge for the enterprise has been getting this data inline into an easily accessible system and providing the contextual integration of the underlying data enriched with insights to be exported into the enterprise’s business applications. The following diagram shows the requirements for this next generation data and insights service or (DaaS): Some quick points on these requirements: Public Data, which in this context is about Common Business Entities, such as - Customers, Suppliers, Partners, Competitors (all are organizations) Contacts, Consumers, Employees (all are people) Products, Brands This data can be broadly categorized incrementally as - Base Utility data (address, industry classification) Public Master Reference data (trade style, hierarchy) Social/Web data (News, Feeds, Graph) Transactional Data generated by enterprise process, workflows etc. This Data has traits of high-volume, variety, velocity etc., and the technology needed to efficiently integrate this data for your needs includes - Change management of Public Reference Data across all categories Applied Big Data to extract statics as well as real-time insights Knowledge Diagnostics and Data Mining As you consider how to deploy this solution, many of our customers will be using an online “cloud” service that provides quality data and insights uniformly to all their necessary applications. In addition, they are requesting a service that is: Agile and Easy to Use: Applications integrated with the service can obtain data on-demand, quickly and simply Cost-effective: Pre-integrated into applications so customers don’t have to Has High Data Quality: Single point access to reference data for data quality and linkages to transactional, curated and social data Supports Data Governance: Becomes more manageable and cost-effective since control of data privacy and compliance can be enforced in a centralized place Data-as-a-Service (DaaS) Just as the cloud has transformed and now offers a better path for how an enterprise manages its IT from their infrastructure, platform, and software (IaaS, PaaS, and SaaS), the next step is data (DaaS). Over the last 3 years, we have seen the market begin to offer a cloud-based data service and gain initial traction. On one side of the DaaS continuum, we see an “appliance” type of service that provides a single, reliable source of accurate business data plus social information about accounts, leads, contacts, etc. On the other side of the continuum we see more of an online market “exchange” approach where ISVs and Data Publishers can publish and sell premium datasets within the exchange, with the exchange providing a rich set of web interfaces to improve the ease of data integration. Why the difference? It depends on the provider’s philosophy on how fast the rate of commoditization of certain data types will occur. How do you decide the best approach? Our perspective, as shown in the diagram below, is that the enterprise should develop an elastic schema to support multi-domain applicability. This allows the enterprise to take the most flexible approach to harness the speed and breadth of public data to achieve value. The key tenet of the proposed approach is that an enterprise carefully federates common utility, master reference data end points, mobility considerations and content processing, so that they are pervasively available. One way you may already be familiar with this approach is in how you do Address Verification treatments for accounts, contacts etc. If you design and revise this service in such a way that it is also easily available to social analytic needs, you could extend this to launch geo-location based social use cases (marketing, sales etc.). Our fundamental belief is that value-added data achieved through enrichment with specialized algorithms, as well as applying business “know-how” to weight-factor KPIs based on innovative combinations across an ever-increasing variety, volume and velocity of data, will be where real value is achieved. Essentially, Data-as-a-Service becomes a single entry point for the ever-increasing richness and volume of public data, with enrichment and combined capabilities to extract and integrate the right data from the right sources with the right factoring at the right time for faster decision-making and action within your core business applications. As more data becomes available (and in many cases commoditized), this value-added data processing approach will provide you with ongoing competitive advantage. Let’s look at a quick example of creating a master reference relationship that could be used as an input for a variety of your already existing business applications. In phase 1, a simple master relationship is achieved between a company (e.g. General Motors) and a variety of car brands’ social insights. The reference data allows for easy sort, export and integration into a set of CRM use cases for analytics, sales and marketing CRM. In phase 2, as you create more data relationships (e.g. competitors, contacts, other brands) to have broader and deeper references (social profiles, social meta-data) for more use cases across CRM, HCM, SRM, etc. This is just the tip of the iceberg, as the amount of master reference relationships is constrained only by your imagination and the availability of quality curated data you have to work with. DaaS is just now emerging onto the marketplace as the next step in cloud transformation. For some of you, this may be the first you have heard about it. Let us know if you have questions, or perspectives. In the meantime, we will continue to share insights as we can.Photo: Erik Araujo, stock.xchng

  • Determining cause of random latency and loading issues

    - by Sherwin Flight
    I'm not sure exactly what details to post in regards to my issue, because I'm not sure what is relevant. Prior to the end of September my websites all loaded quickly, in almost all cases. Loading time wasn't usually more than a few seconds. However, since the end of September I noticed a big increase in page loading times. In some cases pages were taking 30 seconds or more to load. I do have a remote monitoring service monitoring some of the sites as well, and the image below shows the response times over the past month. The response times shown at the beginning of this graph were what the usual response times were prior to this issue occurring. You can see that there has been a significant increase in response times from the beginning to the end of this graph. The thing is, the problem is not happening 100% of the time. If I click through the site, or even just keep refreshing the page, about 25% of the time the pages load quickly, the remaining 75% of the time they load slowly. Sometimes the pages take so long to load that they time out, and don't load at all. I have contacted my hosting provider, and they said things at their end was fine. I don't believe the problem is my home internet provider, because all other websites load without a problem. The server is located in Texas, USA. This also raises another interesting point. My remote monitor checks my site from two locations, California, USA, and London, England. As you can see in the chart below the response time is actually shorter when checked from London, which doesn't seem to make sense, since the server is physically closer to the California monitoring location. I would have expected the London monitoring location to have higher response times since they are physically farther away. I should also point out that in some traceroute test I've done it seem like the first connection to the server seems to take the longest, then after that the rest of the page loads quickly. Below is a little chart showing the times for the first connection to the server. So, what could be causing this problem, and what steps can I take to resolve it or at least narrow down the problem? Sending the request to the server was very quick, and receiving the reply back seems pretty quick, but the WAIT time is really long. So it connects, sends the request, but then waits close to 30 seconds before it starts receiving data back. I am also aware that there are things I can do to speed up page loading times, like reducing the number of CSS and JS files used on a page, compressing images, etc. This is not really what the source of the problem is though, because nothing has really changed on the site since before the problem started, and other sites on the same server are loading slowly as well.

  • Software center is broken and can not be repaired or reinstalled

    - by Michal
    When I open the software center, I am told that I can not use it, for it is broken, and needs to be repaired. First I try to do this automatically, as I was offered. I enter a root password, and then the installation fails. installArchives() failed: reconfiguring packages... reconfiguring packages... reconfiguring packages... reconfiguring packages...

First of all, I've tried reinstalling the center, but it failed due to the same 1.4 dependency as is laid out here. I've googled for help and although I don't understand linux at all, I've tried some suggestions: I've tried editing the dpkg status in /var/lib/dpkg/status which failed because the file could not be found. I've tried purging wine/* but that had unresolved dependencies as well. It's a giant mess.
