  • Connect by Wifi to Sql Server from another computer

    - by Bronzato
    I try to connect by Wifi to Sql Server with Sql Server Management Studio from another computer but it failed. I have a computer with Windows Seven & Sql Server 2008 (lets say the server computer). Next to it, I have a fresh installed computer with Windows Seven & Sql Server Management Studio (let's say the client computer). What I do on the server computer: configure firewall by enabling port 1433 enabled network protocols (TCP/IP) inside Sql Server Configuration Manager checked "Allow remote connections to this server" on server properties in Sql Server Management. started Sql Server Browser restarted services (Sql Server Browser is stopped but I think it is not neccessary, isn't it?) Next, I successfully tested a ping on the port 1433 from my client computer with a tool named tcping (ex: tcping 192.168.1.4 1433). But I still cannot connect from my client computer to Sql Server on my other computer. Ok, something new on this problem: until now, I successfully connected to my "server computer" with Management Studio. What I do is typing the computer name in the server name field in the connection window of Management Studio. My previous (failed) attempt was to type the computer name followed by the instance of sql server (ex: COMPUTER_NAME\SQL2008). I don't know why I only have to type the computer name... Nevermind. Now my new challenge is to succeed connecting my VB6 application to this remote database located on my "computer server". I have a connection string for this but it failed to connect. Here is my connection string: "Provider=SQLOLEDB.1;Password=mypassword;User ID=sa;Initial Catalog=TPB;Data Source=THIERRY-HP\SQL2008" Any idea what's wrong? Thanks

  • What specs to consider when buying SSD?

    - by penyuan
    When I bought "traditional" hard drives, I have been told to consider specs like RPM (5400, 7200, etc.), buffer size (16MB, 32MB etc.), and interface (IDE, SATA, etc.). (did I miss something?) What about solid state drives (SSD)? What are some important specs to consider in terms of performance and reliability? By the way, are SSDs just as reliable as traditional hard drives now? A couple years ago I heard they're not, but that's a "long time" ago now. Thanks for your answer.

  • How do I know which hardware components are compatible when building a computer?

    - by darkie15
    I am trying to setup my own new computer. I haven't done this before and hence needed guidance from all here. I can google out the results for steps to follow for setting up my machine, but I do not understand what components are compatible with each other? For example there must be specific models of motherboard that are compatible with Intel Core i5-2500K Sandy Bridge 3.3GHz. In general, if there is a website that can guide me on all compatible components, that would be great. If not, how would I be able to check compatibility?

  • Building computer: Casing for peripheral sockets is a pain!

    - by burnt1ce
    I have a casing the covers the spacing between the peripheral socket which is standard to have when you buy a motherboard. My problem with these covers is that they have spokes that pushes the motherboard away so the sockets don't even come out of the covers. This also misaligns the screws on my atx motherboard with the holes in my computer case. I usually break these spokes so that i can align my motherboard correctly. Why the heck do motherboard manufacture put spokes on these covers? am i using them wrong? UPDATE Here's an image that i found that shows the plastic casing. http://z.about.com/d/pcsupport/1/5/m/-/-/-/tour%5Fexternal.jpg You can even see the indentation that makes the spokes that pushes the motherboard inwards.

  • How to Identify Which Hardware Component is Failing in Your Computer

    - by Chris Hoffman
    Concluding that your computer has a hardware problem is just the first step. If you’re dealing with a hardware issue and not a software issue, the next step is determining what hardware problem you’re actually dealing with. If you purchased a laptop or pre-built desktop PC and it’s still under warranty, you don’t need to care about this. Have the manufacturer fix the PC for you — figuring it out is their problem. If you’ve built your own PC or you want to fix a computer that’s out of warranty, this is something you’ll need to do on your own. Blue Screen 101: Search for the Error Message This may seem like obvious advice, but searching for information about a blue screen’s error message can help immensely. Most blue screens of death you’ll encounter on modern versions of Windows will likely be caused by hardware failures. The blue screen of death often displays information about the driver that crashed or the type of error it encountered. For example, let’s say you encounter a blue screen that identified “NV4_disp.dll” as the driver that caused the blue screen. A quick Google search will reveal that this is the driver for NVIDIA graphics cards, so you now have somewhere to start. It’s possible that your graphics card is failing if you encounter such an error message. Check Hard Drive SMART Status Hard drives have a built in S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) feature. The idea is that the hard drive monitors itself and will notice if it starts to fail, providing you with some advance notice before the drive fails completely. This isn’t perfect, so your hard drive may fail even if SMART says everything is okay. If you see any sort of “SMART error” message, your hard drive is failing. You can use SMART analysis tools to view the SMART health status information your hard drives are reporting. Test Your RAM RAM failure can result in a variety of problems. If the computer writes data to RAM and the RAM returns different data because it’s malfunctioning, you may see application crashes, blue screens, and file system corruption. To test your memory and see if it’s working properly, use Windows’ built-in Memory Diagnostic tool. The Memory Diagnostic tool will write data to every sector of your RAM and read it back afterwards, ensuring that all your RAM is working properly. Check Heat Levels How hot is is inside your computer? Overheating can rsult in blue screens, crashes, and abrupt shut downs. Your computer may be overheating because you’re in a very hot location, it’s ventilated poorly, a fan has stopped inside your computer, or it’s full of dust. Your computer monitors its own internal temperatures and you can access this information. It’s generally available in your computer’s BIOS, but you can also view it with system information utilities such as SpeedFan or Speccy. Check your computer’s recommended temperature level and ensure it’s within the appropriate range. If your computer is overheating, you may see problems only when you’re doing something demanding, such as playing a game that stresses your CPU and graphics card. Be sure to keep an eye on how hot your computer gets when it performs these demanding tasks, not only when it’s idle. Stress Test Your CPU You can use a utility like Prime95 to stress test your CPU. Such a utility will fore your computer’s CPU to perform calculations without allowing it to rest, working it hard and generating heat. If your CPU is becoming too hot, you’ll start to see errors or system crashes. Overclockers use Prime95 to stress test their overclock settings — if Prime95 experiences errors, they throttle back on their overclocks to ensure the CPU runs cooler and more stable. It’s a good way to check if your CPU is stable under load. Stress Test Your Graphics Card Your graphics card can also be stress tested. For example, if your graphics driver crashes while playing games, the games themselves crash, or you see odd graphical corruption, you can run a graphics benchmark utility like 3DMark. The benchmark will stress your graphics card and, if it’s overheating or failing under load, you’ll see graphical problems, crashes, or blue screens while running the benchmark. If the benchmark seems to work fine but you have issues playing a certain game, it may just be a problem with that game. Swap it Out Not every hardware problem is easy to diagnose. If you have a bad motherboard or power supply, their problems may only manifest through occasional odd issues with other components. It’s hard to tell if these components are causing problems unless you replace them completely. Ultimately, the best way to determine whether a component is faulty is to swap it out. For example, if you think your graphics card may be causing your computer to blue screen, pull the graphics card out of your computer and swap in a new graphics card. If everything is working well, it’s likely that your previous graphics card was bad. This isn’t easy for people who don’t have boxes of components sitting around, but it’s the ideal way to troubleshoot. Troubleshooting is all about trial and error, and swapping components out allows you to pin down which component is actually causing the problem through a process of elimination. This isn’t a complete guide to everything that could likely go wrong and how to identify it — someone could write a full textbook on identifying failing components and still not cover everything. But the tips above should give you some places to start dealing with the more common problems. Image Credit: Justin Marty on Flickr

  • MS in Computer Science after BE in electronics

    - by Abhinav
    I am doing my 3rd year Bachelors in Electronics and Electrical Communication but from the first year I have been interested in Computer Science. But at that time it was just my hobby. But in second year when I joined robotics my love for computer science rose. I with my team came in top three in 2 National Competition (Technical fests of different IITs) where we used Image Processing, Hardware interfacing etc. But then I realised that Computer Science is not just about coding. I took many lectures from online free schools like Udacity, Coursera in subjects related to Artificial Intelligence, Building a Search Engine, Design and Analysis of Algorithm, Programming a Robotic Car, Programming Languages, Machine Learning, Software Engineering as a Service, WebApps Engineering, Compilers, Applied Crypotography etc. I also did some courses in Core and Advanced Java in my second year from training institute. I will also be taking course in Statistics, Databases, Discrete Mathematics from 25th June. Now I realized how vast is the field of Computer Science and how efficient you become on deciding algorithms and classifying problems into different subfields which have been thoroughly researched so you don't always do brute force thing or naive programming. Now this field has become kind of passion for me. Adding to the fact I am also doing my 6 months internship in software field in Texas Instruments where I am working on Automation and Algorithms. I also have some 5-6 good college level projects in Softwares and Robotics. I also like Electronics but only some fields like Operating System(this subject was there in Electronics also), Micro Processor, Digital, Computer Architecture, DSPs etc. I really want to pursue MS in some field of Computer Science. I am giving GRE in October/November. Till now I have good CG of around 9.4/10 and my 1 year in college is still left. Do I have any chance that some good University in US will consider me for MS in field related to computer science or Robotics. Also Can you suggest somethings that I can do during this 1 year to increase my chances for MS or should I apply for EECS(Electrical Engineering and Computer Science) and then I can shift more towards Computer Science as my major option. My main aim is to do Phd after Ms in CS if I am able to do that somehow. I know that I have to put much extra effort to understand things in MS than CS undergraduates but I will do that with my full dedication, also when I communicate with my college CS students or during my internship period I didn't feel that I am missing very much stuff that they know and was very comfortable during my internship with software employees.

  • Developing a computer system based on Nand2Tetris [on hold]

    - by Ryan
    I recently finished a book called Nand2Tetris (nand2tetris.org) where I built my own computer system from scratch with its own machine language, assembly code, and a high level language called Jack that's translated to Hack binary. However, I feel like the "computer" I built throughout the course of this book (called the Hack computer) is a bit too simple for various reasons: 1) There are only two registers (D and A), whereas most computers have much more 2) Peripheral devices like mouse and keyboard have to be directly implemented 3) Peripheral devices use a pre-planned shared memory map to communicate with the CPU instead of using interrupts (which aren't covered at all) 4) Jack (the high level language) code doesn't compile to Assembly code directly, instead it compiles to an intermediate language, which in turn gets translated to Assembly. 5) There is no ROM or permanent storage device, everything is stored in RAM 6) No support for colored monitor, networking or sound I would like to build a more complicated computer system now based on what I've learned from Nand2Tetris. Does anyone know of any good resources or books to get started on this? (BTW by computer system I mean software that can emulate the hardware of a virtual computer with its own unique instruction set)

  • Nexus S 4g not detected by computer

    - by Newbie in over his head
    A little bit of a disclaimer, I have very little knowledge of the correct terminology for some of the things I'm going to ask about, and I apologize in advance I have a Nexus S 4g phone that is, at the moment of writing, connected to my 11.10 computer through its USB charger cable. In the past, connecting the phone like this has allowed me to transfer files between my computer and my phone; I'm able to get my music onto my phone, and my photos onto my computer, for example. For some reason, this has stopped working. My phone still charges its battery when connected to the computer, but neither the computer nor the phone recognized that they are connected. Is there something I can do to get the phone and the computer to detect each other? I don't know how to fix this, and it's more than a little frustrating. Any help would be greatly appreciated.

  • C++ vs Matlab vs Python as a main language for Computer Vision Postgraduate

    - by Hough
    Hi all, Firstly, sorry for a somewhat long question but I think that many people are in the same situation as me and hopefully they can also gain some benefit from this. I'll be starting my PhD very soon which involve the fields of computer vision, pattern recognition and machine learning. Currently, I'm using opencv (2.1) C++ interface and I especially like its powerful Mat class and the overloaded operations available for matrix and image seamless operations and transformations. I've also tried (and implemented many small vision projects) using opencv python interface (new bindings; opencv 2.1) and I really enjoy python's ability to integrate opencv, numpy, scipy and matplotlib. But recently, I went back to opencv C++ interface because I felt that the official python new bindings were not stable enough and no overloaded operations are available for matrices and images, not to mention the lack of machine learning modules and slow speeds in certain operations. I've also used Matlab extensively in the past and although I've used mex files and other means to speed up the program, I just felt that Matlab's performance was inadequate for real-time vision tasks, be it for fast prototyping or not. When the project becomes larger and larger, many tasks have to be re-written in C and compiled into Mex files increasingly and Matlab becomes nothing more than a glue language. Here comes the sub-questions: For postgrad studies in these fields (machine learning, vision, pattern recognition), what is your main or ideal programming language for rapid prototyping of ideas and testing algorithms contained in papers? For postgrad studies, can you list down the pros and cons of using the following languages? C++ (with opencv + gsl + svmlib + other libraries) vs Matlab (with all its toolboxes) vs python (with the imcomplete opencv bindings + numpy + scipy + matplotlib). Are there computer vision PhD/postgrad students here who are using only C++ (with all its availabe libraries including opencv) without even needing to resort to Matlab or python? In other words, given the current existing computer vision or machine learning libraries, is C++ alone sufficient for fast prototyping of ideas? If you're currently using Java or C# for your postgrad work, can you list down the reasons why they should be used and how they compare to other languages in terms of available libraries? What is the de facto vision/machine learning programming language and its associated libraries used in your university research group? Thanks in advance.

  • Embedded computer vision platforms

    - by Egon
    Hi folks, I am planning to start a computer vision based project on a smart phone platform. I know iPhone ( http://niw.at/articles/2009/03/14/using-opencv-on-iphone/en ) and Andriod ( http://github.com/billmccord/OpenCV-Android ) have openCV support. I am interested in knowing how was your experience with the level of integration, support and ease of building good apps on either platform. Also I do want to consider windows phone 7 ( and Zune) as a platform, Are there any Computer Vision libraries for that platform or any good development tools( does Aforgenet work or any other good suggestion) ? Also can you suggest some popular augmented reality apps which uses cutting edge technology ( I am aware of http://www.pranavmistry.com/projects/sixthsense/ ) Thnx in advance!

  • How to run a program on a specific remote computer

    - by lucc
    Hi, I have got this working line of code I would like to run via VBScript a share program on a remote computer in a domain environment. The first part is ok where it is asking me to enter a computer name, but the problem is in the second part. I don't know how to run the program on the remote computer that I've entered in the first part. computer = inputbox ("What computer do you wish to check? (Press Enter if this computer)","Computer") set WMI = GetObject("WinMgmts://" & computer) If computer="" then computer = "this computer" Dim objShell Set objShell = WScript.CreateObject( "WScript.Shell" ) objShell.Run("""\\compname\Share\progr.exe""") Set objShell = nothing After running this script, it runs the program on my computer, not on the remote computer. I want to run the program on a specific computer that I have entered from keyboard. Please help. Thank you.

  • Keeping Computer Science Writing Accessible and Eloquent

    - by Federer
    This question is particularly aimed at descriptions and explanations of what is happening in a computer program, as well as any general advice or approaches for undertaking technical reports in Computer Science at both undergraduate and graduate levels. You see, I am having particular difficulty in the best way to explain what is happening. As in, given any given program from a multi-agent system to a standard webservice, the best and most eloquent way to say exactly what is going on, the logic behind it and it's respective justifications. Should I avoid saying class names? Avoid specifying methods? Keep referring to class variables and any particular references? I'm banging my head against the wall at trying to keep a solid technical foundation and making it accessible to people of all backgrounds. Apologies for the rather vague question. Cheers.

  • Networking conflict - What is the most common default computer name?

    - by John
    I recently had to change the name of my computer to log onto a public wi-fi spot, because a computer with my name was already logged on. (I asked a guy there what to do after it said there was already a computer named "Dell(omitted)" logged on.) I've never been at a wifi spot that you had to log into before. I didn't even notice what the computer's name was before. My question is what are the most common default computer names. I'm curious. How often does this sort of problem happen? (I read via Google that Redhat linux default to "localhost" and Toshiba laptops default to "Toshiba.") Somebody probably keeps statistics. (I was referred here from serverfault.com) Thanks
