  • Conscience and unconscience from an AI/Robotics POV

    - by Tim Huffam
    Just pondering the workings of the human mind - from an AI/robotics point of view (either of which I know little about)..   If conscience is when you're thinking about it (processing it in realtime)... and unconscience is when you're not thinking about it (eg it's autonomous behaviour)..  would it be fair to say then, that:   - conscience is software   - unconscience is hardware   Considering that human learning is attributed to the number of neural connections made - and repetition is the key - the more the connections, the better one understands the subject - until it becomes a 'known'.   Therefore could this be likened to forming hard connections?  Eg maybe learning would progress from an MCU to FPGA's - therefore offloading realtime process to the hardware (FPGA or some such device)? t

  • unzip error "End-of-central-directory signature not found"

    - by Tim
    I try to unzip a zip file, but got an error: $ unzip COCR2_100.zip Archive: COCR2_100.zip End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. note: COCR2_100.zip may be a plain executable, not an archive unzip: cannot find zipfile directory in one of COCR2_100.zip or COCR2_100.zip.zip, and cannot find COCR2_100.zip.ZIP, period. I googled but didn't find a solution. I was wondering why it is and how I should fix it? Thanks! The zip file can be downloaded from COCR2_100. It is an application, and here is its website http://users.belgacom.net/chardic/cocr2.html. My OS is 10.10.

  • Get to No as fast as possible

    - by Tim Hibbard
    There is a sales technique where the strategy is to get the customer to say “No deal” as soon as possible.  The idea being that by establishing terms that your customer is not comfortable with with, the sooner you can figure out what they will be willing to agree to.  The same principal can be applied to code design.  Instead of nested if…then statements, a code block should quickly eliminate the cases it is not equipped to handle and just focus on what it is meant to handle. This is code that will quickly become maintainable as requirements change: private void SaveClient(Client c) { if (c != null) { if (c.BirthDate != DateTime.MinValue) { foreach (Sale s in c.Sales) { if (s.IsProcessed) { SaveSaleToDatabase(s); } } SaveClientToDatabase(c); } } }   If an additional requirement comes along that requires the Client to have Manager approval or for a Sale to be under $20K, this code will get messy and unreadable. A better way to meet the same requirements would be: private void SaveClient(Client c) { if (c == null) { return; } if (c.BirthDate == DateTime.MinValue) { return; }   foreach (Sale s in c.Save) { if (!s.IsProcessed) { continue; } SaveSaleToDatabase(s); } SaveClientToDatabase(c); } This technique moves on quickly when it finds something it doesn’t like.  This makes it much easier to add a Manager approval constraint.  We would just insert the new requirement before the action takes place.

  • Is there a LOGO interpreter that actually has a turtle?

    - by Tim Post
    This is not a repeat of the now infamous "How do I move the turtle in LOGO?" Recently, I had the following conversation with my five year old daughter: Daughter: Daddy, do you write programs? Me: Yes! Daughter: Daddy, what's a program? Me: A program is a set of instructions that a computer follows. Daughter: Daddy, can I write a program too? Me: Sure! This got me scrambling to think of a very basic language that a five year old could get some satisfaction from mastering rather quickly. I'm ashamed to admit that the first thing that came to mind was this: 10 INPUT "Tell me a secret" A$ 20 PRINT "Wow really? :" A$ 30 GOTO 10 That isn't going to hold a five year old's attention for very long and it requires too much of a lecture. However, moving a turtle around and drawing neat pictures might just work. Sadly, my search for a LOGO interpreter yielded noting but ad ridden sites, flight simulators and a whole bunch of other stuff that I really don't want. I'm hoping to find a cross platform (Java / Python) LOGO interpreter (dare I call it simulator?) with the following features: Can save / replay commands (stored programs) Has an actual turtle Sound effects are a plus Have you stumbled across something like this, if so, can you provide a link? I hate to ask a 'shopping' sort of question, but it seemed much better than "Is LOGO appropriate for a five year old?"

  • The partition table is corrupt

    - by Tim
    I have a corrupt the partition table on the laptop that is running Ubunutu 10.4. Before the partition table was corrupt I had the following partitions: 2 primary partitions: 1st - NTFS 2nd - Extended 4 logical partitons that are built within 2nd extended: 1st NTFS (68 Gib) 2nd Linux (19 Gib) 3rd Swap (1.4 Gib) 4th Linux (24 Gib) The physical order of these partitions was the following: ( 4th Linux ) - ( 1st NTFS ) - ( 2nd Linux ) - ( 3rd Swap ) The logical order of the partition was different: ( 1st NTFS ) - ( 2nd Linux ) - ( 3rd Swap ) ( 4th Linux ) NTFS partition was big and it resided between 2 Linux partitions, neither of these partitions had enough space to install Oracle 11g. Therefore, I decided to a) either move the NTFS partion to the left or b) remove it completely and extend partition where Linux resides. As I tool I have chosen GParted. But unfortunately it was not able to move the partition because he found that in NTFS partition there are some blocks that are referenced multiple times. Also it was not able to remove the partition neither, because in this case the partitions that follow it ( 2nd Linux ) - ( 3rd Swap ) have to be in his opinion also removed, because the organization of extended partition is a linked list. Since GParted was not able to do such thing I was trying to find another tool. I found diskdrake tool on PSLinuxOS distribution of linux. That tool silently deleted ( 1st NTFS ) partition and I thought that everything was fine. But diskdrake has damaged the partition in a way that I am not able either to boot from the hard disk nor to see the partitions with GParted and even with diskdrake itself! Fortunately I have a live CD of Ubuntu 8.10 and I am able to boot and see hard disk. I have 2 ideas how I can solve the problem: 1) Manually change disk partitions and point them to the correct partitions. 2) Create partition table with GParted that as much as possible is the same with the previous one I find the 2nd approach less time consuming but some data will be lost because of it is not possible to place borders of the partitions exactly how it was before. And moreover I am not sure if such approach would work, for example, if the OS is able to locate files after repartitioning. I feel like that it will but not 100% sure. Are there some ideas how the problem may be solved?

  • Understanding Application binary interface (ABI)

    - by Tim
    I am trying to understand the concept of Application binary interface (ABI). From The Linux Kernel Primer: An ABI is a set of conventions that allows a linker to combine separately compiled modules into one unit without recompilation, such as calling conventions, machine interface, and operating-system interface. Among other things, an ABI defines the binary interface between these units. ... The benefits of conforming to an ABI are that it allows linking object files compiled by different compilers. From Wikipedia: an application binary interface (ABI) describes the low-level interface between an application (or any type of) program and the operating system or another application. ABIs cover details such as data type, size, and alignment; the calling convention, which controls how functions' arguments are passed and return values retrieved; the system call numbers and how an application should make system calls to the operating system; and in the case of a complete operating system ABI, the binary format of object files, program libraries and so on. I was wondering whether ABI depends on both the instruction set and the OS. Are the two all that ABI depends on? What kinds of role does ABI play in different stages of compilation: preprocessing, conversion of code from C to Assembly, conversion of code from Assembly to Machine code, and linking? From the first quote above, it seems to me that ABI is needed for only linking stage, not the other stages. Is it correct? When is ABI needed to be considered? Is ABI needed to be considered during programming in C, Assembly or other languages? If yes, how are ABI and API different? Or is it only for linker or compiler? Is ABI specified for/in machine code, Assembly language, and/or of C?

  • Creating Corporate Windows Phone Applications

    - by Tim Murphy
    Most developers write Windows Phone applications for their own gratification and their own wallets.  While most of the time I would put myself in the same camp, I am also a consultant.  This means that I have corporate clients who want corporate solutions.  I recently got a request for a system rebuild that includes a Windows Phone component.  This brought up the questions of what are the important aspects to consider when building for this situation. Let’s break it down in to the points that are important to a company using a mobile application.  The company want to make sure that their proprietary software is safe from use by unauthorized users.  They also want to make sure that the data is secure on the device. The first point is a challenge.  There is no such thing as true private distribution in the Windows Phone ecosystem at this time.  What is available is the ability to specify you application for targeted distribution.  Even with targeted distribution you can’t ensure that only individuals within your organization will be able to load you application.  Because of this I am taking two additional steps.  The first is to register the phone’s DeviceUniqueId within your system.  Add a system sign-in and that should cover access to your application. The second half of the problem is securing the data on the phone.  This is where the ProtectedData API within the System.Security.Cryptography namespace comes in.  It allows you to encrypt your data before pushing it to isolated storage on the device. With the announcement of Windows Phone 8 coming this fall, many of these points will have different solutions.  Private signing and distribution of applications will be available.  We will also have native access to BitLocker.  When you combine these capabilities enterprise application development for Windows Phone will be much simpler.  Until then work with the above suggestions to develop your enterprise solutions. del.icio.us Tags: Windows Phone 7,Windows Phone,Corporate Deployment,Software Design,Mango,Targeted Applications,ProtectedData API,Windows Phone 8

  • Handling SMS/email convergence: how does a good business app do it?

    - by Tim Cooper
    I'm writing a school administration software package, but it strikes me that many developers will face this same issue: when communicating with users, should you use email or SMS or both, and should you treat them as fundamentally equivalent channels such that any message can get sent using any media, (with long and short forms of the message template obviously) or should different business functions be specifically tailored to each of the 3? This question got kicked off "StackOverflow" for being overly general, so I'm hoping it's not too general for this site - the answers will no doubt be subjective but "you don't need to write a whole book to answer the question". I'm particularly interested in people who have direct experience of having written comparable business applications. Sub-questions: Do I treat SMS as "moderately secure" and email as less secure? (I'm thinking about booking tokens for parent/teacher nights, permission slips for excursions, absence explanation notes - so high security is not a requirement for us, although medium security is) Is it annoying for users to receive the same message on multiple channels? Should we have a unified framework that reports on delivery or lack thereof of emails and SMS's?

  • How Can I Effectively Interview an Oracle Candidate?

    - by Tim Medora
    First, I browsed through SO for matching questions and didn't find one, but please point me in the right direction if this exact question has already been asked. I work with and around programmers of various skill levels on various platforms. I would consider my skills to be strong in terms of relational database design, query development, and basic performance tuning and administration. I'm mid-level when it comes to database theory. My team is looking to me to ensure that we have the best talent on staff, in this case, an engineer experienced in Oracle administration. To me, a well-rounded database administrator, regardless of platform, should also be competent in developing against the database so that is also a requirement. However my database skills are centralized around SQL Server 200x with experience in a few other products like SAP MaxDB, Access, and FoxPro. How can I thoroughly assess the skills of an Oracle engineer? I can ask high-level database theory questions and talk about routine tasks that are common across platforms, but I want to dig deep enough that I can be confident in the people I hire. Normally, I would alternate very specific questions that have a right/wrong answer with architectural questions that might have several valid answers. Does anyone have an interview template, specific questions, or any other knowledge that they can share? Even knowing the meaningful Oracle-related certifications would be a help. Thank you. EDIT: All the answers have been very helpful so far and I have given upvotes to everyone. I'm surprised that there are already 3 close votes on this question as "off topic". To be clear, I am specifically asking how a MS SQL Server engineer (like myself) can effectively interview a person with different but symbiotic skills. The question has already received specific, technical answers which have improved my own database design and programming skills. If this is more appropriate as a community wiki, please convert it.

  • Dealing with three Windows partitions in dual boot installation

    - by Tim
    For dual-boot installation of Ubuntu after Windows. Quoted from ubuntuguide If a Windows boot partition exists as a second NTFS partition, it should be left alone. If there is a Windows recovery partition also installed, it can also be left alone as long as there are only two NTFS partitions total on the hard drive (i.e. there is no NTFS boot partition as well). If there are a total of 3 NTFS partitions on the hard drive, then the third Windows NTFS partition (the recovery partition) should be removed after creating Recovery CDs from it (see here). In the last case where Windows has three partitions, I was wondering why it says the recovery partition shall be removed? Is it possible to keep the three and create another extended partition with several logical partitions for installing Ubuntu and dual-booting the two OSes? I plan to dual-boot install Ubuntu 10.04 with existing Windows 7. Following is the layout of the current partitions of my hard drive viewed from Windows 7: So must I remove the Lenovo_Recovery (Q:) partition for the same reason you give for the first question? Thanks and regards!

  • How can I remove duplicate icons for "launched" java programs in the launcher?

    - by Tim
    When launching java programs (like IntelliJ IDEA and Crashplan) in Natty's Unity launcher, duplicate icons are shown (see image). For IntelliJ I created the .desktop file, for Crashplan the .desktop file is supplied with the application. Is there something that can be changed in the .desktop files (or somewhere else) that can prevent this from occurring? I couldn't find a bug report for unity itself but programs like Gnome-Do/Docky have bug reports and had to make internal changes to their applications to prevent this. In this image the 1st icon is the one created from the .desktop file and the second icon is after launching it. Second icon disappears when closing the application.

  • Is there some application to download files from popular file hosting websites?

    - by Tim
    I was wondering if there are some applications for downloading files from some popular hosting websites, automating the procedure of waiting and fetching links and downloading files, once we give the applications the links? Examples of such websites are Rapidshare, Uploading, Megaupload, Filesonic, Fileserver, Hotfiles, Depositefiles, iFile. But the applications are not necessarily applicable to all of them. Thanks and regards! ADDED: I just tried slimrat. It failed to download files from rapidshare. Can it be because the website of rapidshare has changed recently and the parsing functionality for their website by slimrat is not up-to-date yet.

  • Microsoft Changes Developer Account Registration Requirements

    - by Tim Murphy
    Over the last couple of weeks I have noticed that Microsoft seems to have changed the requirements for Corporate accounts.  These requirements were not in effect when I originally setup the account for the company that I work for.  We also recently had our corporate account canceled without explanation and are in the process of working to get it reinstated.  This all seems to revolve around rules to increase confidence that in the producers of content.  They are now having Symantec validate a company based on legal documents. In the past there have been problems with getting credit cards accepted.  We have had to setup new Live IDs to satisfy whatever glitch the system had or unexplainable requirement.  I am hoping that in the time that has elapsed these problems have been resolved. In truth I can’t say that these new requirements weren’t always in place, but it is getting frustrating to help clients setup accounts.  I am encourage that they have taken steps to safeguard the consumer from Joe-fly-by-night, but they also need to make sure that the process doesn’t become so complex that it drives away companies from participating in the store.  We will have to keep an eye on this as things evolve. del.icio.us Tags: Windows Phone Development,Windows 8 Development,Windows Phone,Windows 8,Registration,Corporate Accounts

  • Key Windows Phone Development Concepts

    - by Tim Murphy
    As I am doing more development in and out of the enterprise arena for Windows Phone I decide I would study for the 70-599 test.  I generally take certification tests as a way to force me to dig deeper into a technology.  Between the development and studying I decided it would be good to put a post together of key development features in Windows Phone 7 environment.  Contrary to popular belief the launch of Windows Phone 8 will not obsolete Windows Phone 7 development.  With the launch of 7.8 coming shortly and people who will remain on 7.X for the foreseeable future there are still consumers needing these apps so don’t throw out the baby with the bath water. PhoneApplicationService This is a class that every Windows Phone developer needs to become familiar with.  When it comes to application state this is your go to repository.  It also contains events that help with management of your application’s lifecycle.  You can access it like the following code sample. 1: PhoneApplicationService.Current.State["ValidUser"] = userResult; DeviceNetworkInformation This class allows you to determine the connectivity of the device and be notified when something changes with that connectivity.  If you are making web service calls you will want to check here before firing off. I have found that this class doesn’t actually work very well for determining if you have internet access.  You are better of using the following code where IsConnectedToInternet is an App level property. private void Application_Launching(object sender, LaunchingEventArgs e){ // Validate user access if (Microsoft.Phone.Net.NetworkInformation.NetworkInterface.NetworkInterfaceType != Microsoft.Phone.Net.NetworkInformation.NetworkInterfaceType.None) { IsConnectedToInternet = true; } else { IsConnectedToInternet = false; } NetworkChange.NetworkAddressChanged += new NetworkAddressChangedEventHandler(NetworkChange_NetworkAddressChanged);}void NetworkChange_NetworkAddressChanged(object sender, EventArgs e){ IsConnectedToInternet = (Microsoft.Phone.Net.NetworkInformation.NetworkInterface.NetworkInterfaceType != Microsoft.Phone.Net.NetworkInformation.NetworkInterfaceType.None);} Push Notification Push notification allows your application to receive notifications in a way that reduces the application’s power needs. This MSDN article is a good place to get the basics of push notification, but you can see the essential concept in the diagram below.  There are three types of push notification: toast, Tile and raw.  The first two work regardless of the state of the application where as raw messages are discarded if your application is not running.   Live Tiles Live tiles are one of the main differentiators of the Windows Phone platform.  They allow users to find information at a glance from their start screen without navigating into individual apps.  Knowing how to implement them can be a great boost to the attractiveness of your application. The simplest step-by-step explanation for creating live tiles is here. Local Database While your application really only has Isolated Storage as a data store there are some ways of giving you database functionality to develop against.  There are a number of open source ORM style solutions.  Probably the best and most native way I have found is to use LINQ to SQL.  It does take a significant amount of setup, but the ease of use once it is configured is worth the cost.  Rather than repeat the full concepts here I will point you to a post that I wrote previously. Tasks (Bing, Email) Leveraging built in features of the Windows Phone platform is an easy way to add functionality that would be expensive to develop on your own.  The classes that you need to make yourself familiar with are BingMapsDirectionsTask and EmailComposeTask.  This will allow your application to supply directions and give the user an email path to relay information to friends and associates. Event model Because of the ability for users to switch quickly to switch to other apps or the home screen is just one reason why knowing the Windows Phone event model is important.  You need to be able to save data so that if a user gets a phone call they can come back to exactly where they were in your application.  This means that you will need to handle such events as Launching, Activated, Deactivated and Closing at an application level.  You will probably also want to get familiar with the OnNavigatedTo and OnNavigatedFrom events at the page level.  These will give you an opportunity to save data as a user navigates through your app. Summary This is just a small portion of the concepts that you will use while building Windows Phone apps, but these are some of the most critical.  With the launch of Windows Phone 8 this list will probably expand.  Take the time to investigate these topics further and try them out in your apps. del.icio.us Tags: Windows Phone 7,Windows Phone,WP7,Software Development,70-599

  • Who makes laptops for Ubuntu?

    - by Tim Lytle
    I'm looking for a laptop and would like to avoid the whole 'is this [specific configuration of hardware] compatible with Ubuntu?' process by finding a laptop manufactured with Ubuntu in mind. I know of system76, but are there any other manufacturers making laptops built to run a standard build of Ubuntu? I'm not counting Dell, as - from my experience - their 'Ubuntu' laptops/netbooks require their build, and because of that have their own set of compatibility issues. UPDATE: And as mentioned in the comments, Dell is no longer selling systems with Ubuntu to consumers.

  • Review: Windows 8 - Initial Experience

    - by Tim Murphy
    I originally started this post when I had the Windows 8 preview setup on VirtualBox image.  I have since put the RTM bits on a Dell E6530 that is my new work laptop.  It isn’t a table so I am not getting the touch experience, but as a developer this makes the most sense for the moment. This is the first Windows OS that I have had to spend much time exploring to even get started.  The first thing I ran into was when I clicked on the desktop icon I was lost.  Where is the Start menu? Where are my programs?  How do I get back to the Metro environment?  I finally tried hitting the Windows button and it popped back out to the Metro screen. Once I got past that I found that the look of the Metro interface is clean and well organized.  It should be familiar to anyone who is already using a Zune or Windows Phone 7.  In the Desktop, aside from the lack of the Start button to bring up programs the desktop is just like the Windows 7 environment we are all used to.  I do have to say though that I don’t like popping out to the Metro screen to find program.  I think installers for programs like ones that developers usually work in for a desktop mode will need to give an option for creating a desktop icon and pinning to the task bar of the desktop. One of the things I do really enjoy is having live tiles in the Metro environment.  It is a nice way of feeding my need for constant information.  The one drawback though is that the task bar at the bottom of my screen used to be where I got this information without leaving what I was working on.  It allowed me to see current temperatures and when there were messages waiting.  I have since found that these still work as expected in the Desktop and Toast message keep you up on what is going on in the Metro apps. Thankfully familiar functionality like Alt-Tab and Windows-Tab still work regardless of if apps are in the Metro or the Desktop environment.  Add to this the ability to find any application on the Metro screen by simply typing and things get very comfortable. I also started exploring some of the apps.  If you want see a ton of stats on your team at a glance check out the Sports app.  What games are coming up? Who are the leaders in a number of stats?  The Weather and Finance apps have good features as well and I am sure they will improve as users supply feedback. I have had to install Visual Studio 2010 side-by-side with VS2012 because the Windows Phone 7 SDK would only install on VS2010.  This isn’t a Windows 8 issue per se, but something that you need to be aware of if you are a developer moving to the new ecosystem. The overall experience is a joy despite a few hiccups.  For anyone moving to Windows 8 in on a non-touch laptop or desktop I do suggest this list of keyboard shortcuts.  Enjoy. del.icio.us Tags: Windows 8,Win8,Metro,Review

  • All hail the Excel Queen

    - by Tim Dexter
    An excellent question this past week from dear ol Blighty; actually from Brian at Nextgen Clearing Ltd in the big smoke (London). Brian was developing an excel template and wanted to be able to reference the data fields multiple times inside the Excel template. Damn good question and I of course has some wacky solutions, from macros and cell referencing in Excel to pre-processing the data with an XSL stylesheet to copy the data multiple times so it could be referenced multiple times. All completely outlandish, enter our Queen of Excel, Shirley from the development team. Shirley is singlehandedly responsible for the Excel templates, I put her through six months of hell a few years back, with a host of Excel template requirements. She was more than up to the challenge and has developed some great features. One of those, is the ability to use the hidden XDO_METADATA sheet to map the data to custom named fields so they can be used multiple times in the template. So simple and very neat! Excel template and regular Excel users will know that you can only use the naming function once ie the names have to be unique across the workbook so you can not reuse a cell/group name. To get around this you can just come up with as many cell names as you want and map them in the XDO_METADATA sheet to the data columns/fields in your XML data set:. For example: XDO_?DEPTNO_SUMMARY?  <?DEPTNO?> XDO_?DNAME_SUMMARY?  <?DNAME?> XDO_GROUP_?G_D_DETAIL? <xsl:for-each-group select=".//G_D" group-by="./DEPTNO"> XDO_?DEPTNO_DETAIL? <?DEPTNO?> As you can see DEPTNO has been referenced twice and mapped to different named values in the left hand column. These values can then be used to name individual cells in the Excel template. You'll also notice a mix of Publisher <? ...?> and native XSL commands. So the world is your oyster on the mapping and the complexity you might need for calculations or string manipulation. Shirley has kindly built out a sample Excel template, data and result here so you can see how it all hangs together. the XDO_METADATA sheet is hidden, just right click on the sheet names and use the Unhide command to show it.

  • Are null references really a bad thing?

    - by Tim Goodman
    I've heard it said that the inclusion of null references in programming languages is the "billion dollar mistake". But why? Sure, they can cause NullReferenceExceptions, but so what? Any element of the language can be a source of errors if used improperly. And what's the alternative? I suppose instead of saying this: Customer c = Customer.GetByLastName("Goodman"); // returns null if not found if (c != null) { Console.WriteLine(c.FirstName + " " + c.LastName + " is awesome!"); } else { Console.WriteLine("There was no customer named Goodman. How lame!"); } You could say this: if (Customer.ExistsWithLastName("Goodman")) { Customer c = Customer.GetByLastName("Goodman") // throws error if not found Console.WriteLine(c.FirstName + " " + c.LastName + " is awesome!"); } else { Console.WriteLine("There was no customer named Goodman. How lame!"); } But how is that better? Either way, if you forget to check that the customer exists, you get an exception. I suppose that a CustomerNotFoundException is a bit easier to debug than a NullReferenceException by virtue of being more descriptive. Is that all there is to it?

    Just out of curiosity I decided to find out what the most frequently post were on my blog.  I knew what number one would be just from checking daily stats from time to time.  The main theme that I found in the data is that either pain or humor can really bring people to find your posts.  My most viewed post is on turning off Toshiba Flashcards at over 54K views (I think Toshiba should take notice of this massive fail).  The second highest is on Interesting Blog titles.  This was nothing more than a post that I had put up on a whim of humorous blog titles I had run across.  This post earned over 26K views.  Going down from there the theme stays the same either people looking for something humorous or people with a problem that you have an answer for are the posts that are most likely to get attention.  Remember that blogging can be a great service to your readers.  Keep it interesting and they will come. del.icio.us Tags: Blogging,Blog Topics,Blog Stats

  • Browsing redirected and ad playing in background - Malware?

    - by Tim
    Recently i have noticed when browsing a web page will be redirected to something other than what i click on. For instance, when i tried going to www.askubuntu.com via a link on ubuntu.com it redirected me to some other site than this one. Also when on a page with no flash videos of any kind or pop up windows an ad will start playing. The only way to get it to stop is to wait for it to finish or close the browser and start over again. I have run Clam AV but it has not found anything.

  • 2012&ndash;The End Of The World Review

    - by Tim Murphy
    The end of the world must be coming.  Not because the Mayan calendar says so, but because Microsoft is innovating more than Apple.  It has been a crazy year, with pundits declaring not that the end of the world is coming, but that the end of Microsoft is coming.  Let’s take a look at what 2012 has brought us. The beginning of year is a blur.  I managed to get to TechEd in June which was the first time that I got to take a deep dive into Windows 8 and many other things that had been announced in 2011.  The promise I saw in these products was really encouraging.  The thought of being able to run Windows 8 from a thumb drive or have Hyper-V native to the OS told me that at least for developers good things were coming. I finally got my feet wet with Windows 8 with the developer preview just prior to the RTM.  While the initial experience was a bit of a culture shock I quickly grew to love it.  The media still seems to hold little love for the “reimagined” platform, but I think that once people spend some time with it they will enjoy the experience and what the FUD mongers say will fade into the background.  With the launch of the OS we finally got a look at the Surface.  I think this is a bold entry into the tablet market.  While I wish it was a little more affordable I am already starting to see them in the wild being used by non-techies. I was waiting for Windows Phone 8 at least as much as Windows 8, probably more.  The new hardware, better marketing and new OS features I think are going to finally push us to the point of having a real presence in the smartphone market.  I am seeing a number of iPhone users picking up a Nokia Lumia 920 and getting rid of their brand new iPhone 5.  The only real debacle that I saw around the launch was when they held back the SDK from general developers. Shortly after the launch events came Build 2012.  I was extremely disappointed that I didn’t make it to this year’s Build.  Even if they weren’t handing out Surface and Lumia devices I think the atmosphere and content were something that really needed to be experience in person.  Hopefully there will be a Build next year and it’s schedule will be announced soon.  As you would expect Windows 8 and Windows Phone 8 development were the mainstay of the conference, but improvements in Azure also played a key role.  This movement of services to the cloud will continue and we need to understand where it best fits into the solutions we build. Lower on the radar this year were Office 2013, SQL Server 2012, and Windows Server 2012.  Their glory stolen by the consumer OS and hardware announcements, these new releases are no less important.  Companies will see significant improvements in performance and capabilities if they upgrade.  At TechEd they had shown some of the new features of Windows Server 2012 around hardware integration and Hyper-V performance which absolutely blew me away.  It is our job to bring these important improvements to our company’s attention so that they can be leveraged. Personally, the consulting business in 2012 was the busiest it has been in a long time.  More companies were ready to attack new projects after several years of putting them on the back burner.  I also worked to bring back momentum to the Chicago Information Technology Architects Group.  Both the community and clients are excited about the new technologies that have come out in 2012 and now it is time to deliver. What does 2013 have in store.  I don’t see it be quite as exciting as 2012.  Microsoft will be releasing the Surface Pro in January and it seems that we will see more frequent OS update for Windows.  There are rumors that we may see a Surface phone in 2013.  It has also been announced that there will finally be a rework of the XBox next fall.  The new year will also be a time for us in the development community to take advantage of these new tools and devices.  After all, it is what we build on top of these platforms that will attract more consumers and corporations to using them. Just as I am 99.999% sure that the world is not going to end this year, I am also sure that Microsoft will move on and that most of this negative backlash from the media is actually fear and jealousy.  In the end I think we have a promising year ahead of us. del.icio.us Tags: Microsoft,Pundits,Mayans,Windows 8,Windows Phone 8,Surface
