  • memristor is a new paradigm (fourth element in integrated circuits)? [closed]

    - by lsalamon
    The memristor will bring a new paradigm of programming, opened enormous opportunities to enable the machines to gain knowledge, creating a new paradigm toward the intelligence altificial. Do you believe that we are paving the way for the era of intelligent machines? More info about : Brain-like systems? "As for the human brain-like characteristics, memristor technology could one day lead to computer systems that can remember and associate patterns in a way similar to how people do. This could be used to substantially improve facial recognition technology or to provide more complex biometric recognition systems that could more effectively restrict access to personal information. These same pattern-matching capabilities could enable appliances that learn from experience and computers that can make decisions." [EDITED] The way is open.

  • How to Create VBA Add-In with Shared Codes for All Excels?

    - by StanFish
    I'm writing VBA codes for multiple Excel spreadsheets, which will be shared with others from time to time. At some point I find there are lots of duplications in my works. So I want to find a way to share codes in a sort of Excel add-in, like the .xla file. But when I tried to save the Excel file containing shared codes as .xla file, I got some problems: The file cannot be edit anymore after I save it in the default add-in folder If I move the .xls file to a folder other than the add-in folder, and open it directly - I cannot use its classes - which creates problems for sharing the codes Any ideas to create add-ins in a flexible and powerful way please? Thanks a lot for the help

  • Calling javascript function with arguments using JSNI

    - by jav_000
    I'm trying to integrate Mixpanel with GWT, but I have problems calling an event with a property and one value. My function to track an simple event (without values): public native void trackEvent(String eventName)/*-{ $wnd.mixpanel.track(eventName); }-*/; It works. But when I want to add some properties and values, it doesn't work properly: public native void trackComplexEvent(String eventName, String property, String value)/*-{ $wnd.mixpanel.track(eventName, {property:value}); }-*/; I have 2 problems with this: 1) Mixpanel says the property name is: "property"(yes, the name of the variable that I'm passing, not the value). 2) Mixpanel says the value is:undefined An example from mixpanel web is: mixpanel.track("Video Play", {"age": 13, "gender": "male"}); So, I guess the problem is I'm doing a wrong call or with wrong type of arguments.

  • alternate way to read excel files without providing "network service" security.

    - by Jebli
    Hi, I am using a web application to read the excel file and uploading it in the database. I have deployed the application in the server.I am using windows service 2003 as the server.I am able to read the excel file only if i set the set the security settings to "network service" for the microsoft excel application in the control panel -- administrative tools -- componetn service -- computer -- My computer -- DCOM config -- microsoft excel application . Why is it so . There are also other applications running in the server. 1) Doing like this will create any issue ? 2) Why do we need to do it ? 3) Is there any alternative way to do it ? 4) What are we doing actually by providing network service access ? Please help

  • Is it possible to do have Capistrano do a checkout over a reverse SSH tunnel?

    - by James A. Rosen
    I am developing an application that resides on a public host but whose source I must keep in a Git repository behind a corporate firewall. I'm getting very tired of the slowness of deploying via scp (copying the whole repository and shipping it over SSH on each deploy) and would like to have the remote host simply do a git pull to update. The problem is that the firewall prohibits incoming SSH connections. Would it be possible for me to set up an SSH tunnel from my computer to the deployment computer and use my repository as the source for the git pull? After all, git is distributed, so my copy is just as valid a repository as the central one. If this is possible, what would the tunnel command and the Capistrano configuration be? I think the tunnel will look something like ssh -R something:deployserver.com:something [email protected]

  • How to import and export only data of whole database in access 2007

    - by DiegoMaK
    Hi, I have two identical databases with same structure, database a in computer a and database b in computer b. The data of database a*(a.accdb)* and database b*(b.accdb)* are different. then in database a i have for example ID:1, 2, 3 and in database B i Have ID:4,5,6 Then i need merge these databases data in only one database(a or b, doesn't matter) so the final database looks like. ID:1,2,3,4,5,6 I search an easy way to do this. because i have many tables. and do this by union query is so tedious. I search for example for a backup option for only data without scheme as in postgreSQl or many others RDBMS, but i don't see this options in access 2007. pd:only just table could be duplicate values(i guess that pk doesn't allow copy a duplicate value and all others values will be copied well). if i wrong please correct me. thanks for your help.

  • Verizon Fivespot firewall exceptions

    - by Patrick
    I have a Verizon Fivespot Wi-Fi router and am having issues connecting to the computer that uses it to get on the internet. I am able to connect to the Fivespot admin pages remotely and I am able to connect to the internet from the computer behind the Fivespot. I've tried asking this on superuser but have gotten nothing, I figure this is pertinent to programmers working on remote computers as well. There are two sections pertinent to this issue, Port Filtering And, Port Forwarding I've tried each individually and both together but cannot access anything through the router except for the admin page. I am trying to connect through SSH on Port 22 to an Ubuntu 10.04 box over wifi. I have called Verizon Tech Support but they were unhelpful, the person essentially read what it says on each screen without any elaboration. Any help is greatly appreciated!

  • Help debugging Apache, Passenger and Rails problem

    - by Matt Dressel
    We have an environment running that uses Apache, Passenger and rails. The system is handling most request normally, yet certain requests do not make it to the rails application. For instance, a request to /books is successful, but /books/1 hits apache and passenger, but does not even make it to rails. We set the apache log level to debug and the passenger log level to 3 so that we could monitor all incoming requests. We could see each request coming through and even the /books/1 request is being handled by passenger. But it never gets to rails. Is there any way to determine where the request goes between Passenger and rails or where debugging information might live? Has anyone ever seen any problems with passenger spawning or queuing? We have spawning set to conservative. Also, we have had some permission/ownership problems in the past, so I am not ruling this out yet. Thanks in advance

  • Cuda program results are always zero in HW, correct in EMU??

    - by Orion Nebula
    Hi all! I am having a weird problem .. I have written a CUDA code which executes correctly in emulation and all results show up.. however, when executed on hardware "G210" .. the results in the result memory are always 0 I am passing two vectors to the kernel, one with random variables the other is initialized to zero, the code copies the first vector to shared memory, does some swapping and other operations and then writes back the results on the second vector (the one with the initial 0's) I am using double precision, the -arch sm13 flag is used, all memory allocation also use sizeof(double) .. I have checked if the kernel is invoked, it does .. so no problems here .. the cudaMemCpy has no problems .. what could be the problem .. :( why would it work in emulation but not on HW I am quite confused .. any ideas?

  • Should class IOException in Java have been an unchecked RuntimeException?

    - by Derek Mahar
    Do you agree that the designers of Java class java.io.IOException should have made it an unchecked run-time exception derived from java.lang.RuntimeException instead of a checked exception derived only from java.lang.Exception? I think that class IOException should have been an unchecked exception because there is little that an application can do to resolve problems like file system errors. However, in When You Can't Throw An Exception, Elliotte Rusty Harold claims that most I/O errors are transient and so you can retry an I/O operation several times before giving up: For instance, an IOComparator might not take an I/O error lying down, but — because many I/O problems are transient — you can retry a few times, as shown in Listing 7: Is this generally the case? Can a Java application correct I/O errors or wait for the system to recover? If so, then it is reasonable for IOException to be checked, but if it is not the case, then IOException should be unchecked so that business logic can delegate handling of this exception to a separate system error handler.

  • Does Wicket hamper SEO or search engines ability to crawl?

    - by Nick
    We're coming from GWT projects and because of problems with SEO not liking GWT for our next project we're going to move clear of GWT (mainly because seo is a high priority for this next project). In choosing a new framework, I'm looking at Wicket and liking what I've seen so far. I've only done a few tutorials, but in looking at the war layout (from these tutorials) it looks like most of the html pages are in the WEB-INF folder. It this going to cause problems for SEO and search engines crawling through the sites files? Ideally, I'd like to use Wicket with some AJAX and deploy to Google App Engine.

  • jQuery - Slideshow with different sized images and text

    - by NicoJuicy
    I need some sort of slideshow, with text (something like moving boxes would be nice). I have tried several, but i'm always having problems with different sized images (the images can be for eg. 500px x 300px, but the next one can be 500px, 300px), this gives some problems with the pictures ... I hope you understand what i mean. It's very irritating to find a good jquery plugin that can deal with this problem... :( Can anyone find me a good working one or an alternative to jQuery?

  • How do I add "Press any key to boot from usb" when installing Windows from a flash drive? (Grub4dos question / how to remove a bootloader)

    - by Vincent
    Hi there! I've been struggling with this problem for a while now and finially decided to ask for help. Let me first explain what the main purpose of the app is: to provide the a very easy to use way of backing up files, after which I format the drive and start Windows 7 setup. I do this by booting WinPE, which runs a script to detect Windows installations and then opens a file browser. After the file browser is closed, the script continues and formats the drive that contains the Windows installation, and starts an unattended Windows 7 install. Now here is the problem: When you start Windows setup or WinPE from a dvd, you get a nice option to "Press any key to boot from DVD". This is to prevent the computer from booting the DVD when the first phase of the installation is complete and the computer reboots. However, when booting from a flash drive, Windows does not provide this option: it simply boots the flash drive every reboot. To replicate the "press any key" function, I installed Grub4Dos, which works great. It provides a small menu, the first standard item being "Continue installation", the second being "start installation". After quite a lot of tweaking, I got everything working: Start installation starts WinPE, which in turn starts the Windows installation. At first reboot, the Grub4Dos menu comes up, counts 5 seconds and boots the second stage of the installation. Here, I am greeted with the error: "Windows setup could not configure windows to run on this computer's hardware." When I boot into WinPE the normal way (put the bootmgr on the stick root) and change my bios to boot from the primary hdd after first reboot, I don't get this error. I've been looking around, and the only thing I could find was that the BIOS automatically names the boot device hd0, and that Windows can only be run / installed to hd 0. I'm not sure if this is the problem. I read about remapping to solve this problem, but to do that you have to know the phisical location of the hard drive and partition, like hd(0,1). I want this flash drive to work on any PC, regardless of where the OS is installed, so that's not really a possibility. A possible fix I thought of is removing the bootloader from the flash drive when I'm in WinPE. That way, when the pc reboots the BIOS will not see the flash drive as a boot drive and instead boot the primary hdd. I have yet to find a way to do this. Thank you for reading my question, and if you have any suggestion, please do.

  • Programming language for fast calculations with big integers

    - by sub
    I'm doing Project Euler problems at the moment and I can solve most of them using my own programming language which uses direct C++ integers (so they are bound to 2^32 on my machine). However, at times there are problems which require me to work with very high numbers, I can't do that with native integers. So I implemented a BigInt library in my language which unfortunately gets extremely slow at times. Is there a programming language suitable for very efficient handling of big numbers? I mean that I want to do the things I could do in other programming languages with it (variables, loops, etc.), but in a faster way. If you have got tips for workarounds of the 2^32 limit in my language/C++/other languages, please tell me too!

  • What to see in India as a developer and student

    - by lasseespeholt
    Hi, I'm planning a trip to India around July-August. And I want to hear Indian developers or developers traveled to India if there are something interesting to see in India (around Bombay) for developers in general. Maybe a conference etc. I have looked at http://www.conferencealerts.com/computing.htm I have studied computer science in a year now but have been a spare time and independent developer for some years now. Furthermore, I have tried finding summer courses but that is properly too late now and computer science summer courses is hard to find in India. Best regards, Lasse Espeholt

  • CUDA driver installation on a laptop with nVidia NVS140M card

    - by stanigator
    I'm trying to first figure out if my computer contains a CUDA-enabled card. It has an nVidia NVS 140M card, but I can't seem to figure out if it is the 128 MB version or 256 MB version. On the laptop purchase receipt, I found out that I ordered the 128 MB version, but the control panel description of the card said otherwise as shown below: When I ran the CUDA driver from nVidia's site, it cannot find a hardware compatible with CUDA (even though the product series is CUDA-enabled, the card does not have 256 MB minimum of memory to do so). What would be your recommendations in this case with trying to use CUDA on this computer (I'm not sure if nothing can be done at this point)? Thanks in advance.

  • What are some useful SQL statements that should be known by all developers who may touch the Back en

    - by Jian Lin
    What are some useful SQL statements that should be known by all developers who may touch the Back end side of the project? (Update: just like in algorithm, we know there are sorting problems, shuffling problems, and we know some solutions to them. This question is aiming at the same thing). For example, ones I can think of are: Get a list of Employees and their boss. Or one with the employee's salary greater than the boss. (Self-join) Get a list of the most popular Classes registered by students, from the greatest number to the smallest. (Count, group by, order by) Get a list of Classes that are not registered by any students. (Outer join and check whether the match is NULL, or by Get from Classes table, all ClassIDs which are NOT IN (a subquery to get all ClassIDs from the Registrations table)) Are there some SQL statements that should be under the sleeve of all developers that might touch back end data?

  • Communication via internet in Java

    - by Stuart
    What I mean is like servers on video games. You can run an application and it will set up a server on your computer with an IP and a port. For example, how would you make an application where one host application sets up a thing where it has an IP and a port, and another computer that has access to the internet as well can type in the IP and port and it would be able to communicate with the host? I mean simple communication, like sending a boolean or String. And would there be any security problems that would be needed to fix?

  • What is the difference between remote procedure call and web service

    - by xiao
    Is there any clear definition about RPC and Web Service? A quick wikipedia search shows: RPC: Remote procedure call (RPC) is an Inter-process communication technology that allows a computer program to cause a subroutine or procedure to execute in another address space (commonly on another computer on a shared network) without the programmer explicitly coding the details for this remote interaction. Web Service: Web services are typically application programming interfaces (API) or web APIs that are accessed via Hypertext Transfer Protocol and executed on a remote system hosting the requested services. Web services tend to fall into one of two camps: Big Web Services[1] and RESTful Web Services. I am not quite clear what the real difference between the two things. It seems that one thing could belongs to RPC and is kind of web service at the same time. Is Web Service a higher level representation of RPC?

  • How do I generate (and label) a random integer with python 3.2?

    - by An hero
    Okay, so I'm admittedly a newbie to programming, but I can't determine how to get python v3.2 to generate a random positive integer between parameters I've given it. Just so you can understand the context, I'm trying to create a guessing-game where the user inputs parameters (say 1 to 50), and the computer generates a random number between the given numbers. The user would then have to guess the value that the computer has chosen. I've searched long and hard, but all of the solutions I can find only tell one how to get earlier versions of python to generate a random integer. As near as I can tell, v.3.2 changed how to generate and label a random integer. Anyone know how to do this? Thanks!
