  • Multiple "My Documents" folders?

    - by Flasimbufasa
    I am having the issue, where, I have 2 folders called "My Documents". I recently edited my registry to make "Document" link in the Windows 7 start menu be a FOLDER link and not a LIBRARY link.. Here is the Registry Key information for the Documents key: Key Name: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FolderDescriptions\{7b0db17d-9cd2-4a93-9733-46cc89022e7c} Class Name: <NO CLASS> Last Write Time: 3/2/2011 - 2:33 AM Value 0 Name: Attributes Type: REG_DWORD Data: 0x1 Value 1 Name: Category Type: REG_DWORD Data: 0x4 Value 2 Name: Icon Type: REG_EXPAND_SZ Data: %SystemRoot%\system32\imageres.dll,-1002 Value 3 Name: LocalizedName Type: REG_EXPAND_SZ Data: @%SystemRoot%\system32\shell32.dll,-34575 Value 4 Name: Name Type: REG_SZ Data: Documents Value 5 Name: PublishExpandPath Type: REG_DWORD Data: 0x1 Value 6 Name: PrecCreate Type: REG_DWORD Data: 0x1 Value 7 Name: RelativePath Type: REG_SZ Data: Documents Value 8 Name: Roamable Type: REG_DWORD Data: 0x1 Also, Navigating through computer to "C:\Users\Flasimbufasa\" Only shows one folder called "Documents" However, whenever I navigate to user profile from "Desktop\Flasimbufasa" I get 2 Document folders. Any help?

  • How do I create my own programming language and a compiler for it

    - by Dave
    I am thorough with programming and have come across languages including BASIC, FORTRAN, COBOL, LISP, LOGO, Java, C++, C, MATLAB, Mathematica, Python, Ruby, Perl, Javascript, Assembly and so on. I can't understand how people create programming languages and devise compilers for it. I also couldn't understand how people create OS like Windows, Mac, UNIX, DOS and so on. The other thing that is mysterious to me is how people create libraries like OpenGL, OpenCL, OpenCV, Cocoa, MFC and so on. The last thing I am unable to figure out is how scientists devise an assembly language and an assembler for a microprocessor. I would really like to learn all of these stuff and I am 15 years old. I always wanted to be a computer scientist some one like Babbage, Turing, Shannon, or Dennis Ritchie. I have already read Aho's Compiler Design and Tanenbaum's OS concepts book and they all only discuss concepts and code in a high level. They don't go into the details and nuances and how to devise a compiler or operating system. I want a concrete understanding so that I can create one myself and not just an understanding of what a thread, semaphore, process, or parsing is. I asked my brother about all this. He is a SB student in EECS at MIT and hasn't got a clue of how to actually create all these stuff in the real world. All he knows is just an understanding of Compiler Design and OS concepts like the ones that you guys have mentioned (ie like Thread, Synchronisation, Concurrency, memory management, Lexical Analysis, Intermediate code generation and so on)

  • If I install Ubuntu 12.04, will it recognize all of my RAM?

    - by user91048
    I have a question that's been bugging me since a long time. A friend of mine told me that when he had Ubuntu 11.10 installed the OS only recognized 3.4GB instead of 8GB. In the next week I'll be buying a new computer and I'll have 8GB of RAM, does the Video Card need to have it's own video memory for the OS to recognize the RAM entirely?. If you could give me some advise on how to configure my PC before I buy it it would be great. Thanks. Tengo una duda que me ronda de hace tiempo. Un amigo mio me comento que con ubuntu 11.10 tenia 8 gb de RAM y que solo le reconocia 3.4. Dentro de unos 5 dias me comprare un ordenador nuevo a base de componentes y voy a meterle 8 gb de RAM. ¿Hace falta que la tarjeta gráfica tenga Gb dedicados para que el sistema me reconozca la RAM entera? Si podeis darme algunos consejillos sobre como configurar el PC antes de comprarmelo para que ese problema no me pase, Muchisimas Gracias.

  • Downloading videos from a flash website

    - by Mimi
    There are those plugins that can capture flash videos from websites like Youtube and others. There's also the browsing cache which keeps the videos and I can copy them somewhere else and have them stored on my computer. I know of these, but how can I download a video from a website that (I think) is all flash because the address doesn't change wherever you navigate to and so it stays the same when you play a video that's on the website? No plugin I've tried (realplayer, ant video downloadr, IDM) have worked with it and nothing gets cached from that website.

  • Intermittent ethernet connectivity

    - by Amey Jah
    I am facing a weird problem. I am connecting to my dsl modem via ethernet. After booting, sometimes Ubuntu 10.10 does not detect the eth0 card properly or does not connect to the modem. I have made the following observations: My modem is fully on. All indicators are on except ethernet, which is blinking continuously. My network indicator applet informs me that I am connected to modem, but I am not able to browse as it has not established connection with modem. I need to power off and on (restart) the modem several times OR disconnect/connect (via network applet) several times, before the system can establish a connection with the modem. Once it establishes the connection, the ethernet LED (on modem) stops blinking and glows continuously. However, I do not see this problem every time I reboot or start my computer. 3/5 time, it connects to the modem in a single attempt. Friends, I am not able to understand root cause of this problem. Plus I do not know what kind of logs should be attached. If you want any logs please give me command to run, and I will paste the result for you. Note: I ran system testing when above problem happened. Follow this link to download result.

  • Intel Pentium 4 vs. Faster Celeron

    - by Synetech inc.
    A few months ago my motherboard died, so I bought a used computer that had a 2.4GHz Celeron. My old system had a 1.7GHz Pentium 4, so now I’m trying to decide which CPU to use. Obviously a P4 is preferable over a Celeron, but the Celeron is (significantly?) faster than the P4. I’m wondering if the faster Celeron might be better for certain tasks (ie, stronger but dumber is better at some things than smarter but weaker). I tried Googling for some reviews and comparisons for graphs to get a clear depiction of which is better overall, but found nothing that helped. (I did manage to find one page that indicates (apparently by poll, not benchmark) that the Celeron is better.) So which CPU should I use? Does anyone know of some graphs that I can use to compare the two?

  • I don't understand the definition of side effects

    - by Chris Okyen
    I don't understand the wikipedia article on Side Effects: In computer science, a function or expression is said to have a side effect if, in addition to returning a value, it also 1.) Modifies some state or 2.) Has an observable interaction with calling functions or the outside world. I know an example of the first thing that causes a function or expression to have side effects - modifying a state Function and Expression modifying a state : 1.) foo(int X) { return x = x % x; } a = a + 1; What does 2.) - Has an observable interaction with calling functions or the outside world," mean? - Please give an example. The article continues on to say, "For example, a function might modify a global or static variable, modify one of its arguments, raise an exception, write data to a display or file, read data, or call other side-effecting functions...." Are all these examples, examples of 1.) - Modifiying some state , or are they also part of 2.) - Has an observable interaction with calling functions or the outside world?

  • Power cut during Ubuntu upgrade to 10.04 - boots to command line, apt-get and dpkg do not work.

    - by Macha
    I was upgrading Ubuntu to 10.04, when a tripswitch tripped, cutting power to the computer. When it was restarted, it booted into a command line prompt. Google tells me to try: sudo dpkg --configure -a This gets me a lot of output that ends with a list of packages. I can't tell you what the output is, as piping the output to more/less does not work (still just all scrolls by and moves to next prompt), and redirecting it to a file just results in an empty file. Google also suggested: sudo apt-get install -f This also didn't work. Is a fresh install the only solution at this point?

  • AMD FX 8350 potentially overheating

    - by rhughes
    I am worried that my CPU is overheating when running at maximum capacity. I have not overclocked the machine. The machine often powers down after a couple of minutes of max CPU usage. I get the following events in the Event Log after the crash: Log Name: System Source: Microsoft-Windows-Kernel-Power Date: 11/10/2013 12:05:40 Event ID: 41 Task Category: (63) Level: Critical Keywords: (2) User: SYSTEM Computer: home-pc Description: The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. What can I do to confirm this or further narrow down this issue? Due to the sudden nature of the crash, no MEMORY.DMP is created I believe. I am happy to post any extra information that is needed.

  • Possible to install Xmonad on Ubuntu separate from Gnome?

    - by Kurtosis
    I just downloaded Xmonad from the repository on my Ubuntu 10.04 box, but when I log out and try to log back in using Xmonad instead Gnome, it doesn't work. I just get the login screen background image and a mousepointer, and nothing else. Right-clicking does nothing, no menus or anything. Key combo's like Ctrl-X, Ctrl-Z, and Ctrl-Alt-Delete do nothing either. Left the computer in this state for 30 minutes while I went to the grocery store, but it was still hung when I returned and I had to hard-reboot it. A Google search returned a few sites showing how to configure Xmonad to work with Gnome, but I'm afraid to try this since I don't want to risk borking my Gnome installation, at least not until I've had a chance to learn Xmonad a bit. Is it possible to run Xmonad independently of Gnome? If so, anyone have any idea what might be wrong and how to fix it?

  • Bluetooth radio device is not available

    - by Mike
    I reinstalled my Windows 7 operating system, and have since been unable to detect my Logitech m555b bluetooth mouse. Here is some info about my system: I have have a working connection with a bluetooth printer. I have a message in the "My Bluetooth" section of explorer stating "Bluetooth radio device is not available". The Device Manager indicates that the Generic Bluetooth radio is working correctly. The bluetooth "F12" switch is on. Mouse batteries are new and the right way around. I'm presuming that I need a bluetooth driver which is non generic. The computer is a Clevo P150HMx (the version with the GTX485 GPU) with the default WLAN / bluetooth combo card manufactured by Realtek (I think it's a Realtek RTL8188CE card). I think I have the drivers installed, but I still get the generic driver in the Device Manager. I'm confused. Please help, I'm going mad on the touchpad. (Thanks for the touchup wizlog)

  • Transmission shutdown script for multiple torrents?

    - by Khurshid Alam
    I have written a shutdown script for transmission. Transmission calls the script after a torrent download finishes. The script runs perfectly on my machine (Ubuntu 11.04 & 12.04). #!/bin/bash sleep 300s # default display on current host DISPLAY=:0.0 # find out if monitor is on. Default timeout can be configured from screensaver/Power configuration. STATUS=`xset -display $DISPLAY -q | grep 'Monitor'` echo $STATUS if [ "$STATUS" == " Monitor is On" ] ### Then check if its still downloading a torrent. Couldn't figure out how.(May be) by monitoring network downstream activity? then notify-send "Downloads Complete" "Exiting transmisssion now" pkill transmission else notify-send "Downloads Complete" "Shutting Down Computer" dbus-send --session --type=method_call --print-reply --dest=org.gnome.SessionManager /org/gnome/SessionManager org.gnome.SessionManager.RequestShutdown fi exit 0 The problem is that when I'm downloading more than one file, when the first one finishes, transmission executes the script. I would like to do that but after all downloads are completed. I want to put a 2nd check ( right after monitor check) if it is still downloading another torrent. Is there any way to do this?

  • Are there any concrete examples of where a paralellizing compiler would provide a value-adding benefit?

    - by jamie
    Paul Graham argues that: It would be great if a startup could give us something of the old Moore's Law back, by writing software that could make a large number of CPUs look to the developer like one very fast CPU. ... The most ambitious is to try to do it automatically: to write a compiler that will parallelize our code for us. There's a name for this compiler, the sufficiently smart compiler, and it is a byword for impossibility. But is it really impossible? Can someone provide a concrete example where a paralellizing compiler would solve a pain point? Web-apps don't appear to be a problem: just run a bunch of Node processes. Real-time raytracing isn't a problem: the programmers are writing multi-threaded, SIMD assembly language quite happily (indeed, some might complain if we make it easier!). The holy grail is to be able to accelerate any program, be it MySQL, Garage Band, or Quicken. I'm looking for a middle ground: is there a real-world problem that you have experienced where a "smart-enough" compiler would have provided a real benefit, i.e that someone would pay for? A good answer is one where there is a process where the computer runs at 100% CPU on a single core for a painful period of time. That time might be 10 seconds, if the task is meant to be quick. It might be 500ms if the task is meant to be interactive. It might be 10 hours. Please describe such a problem. Really, that's all I'm looking for: candidate areas for further investigation. (Hence, raytracing is off the list because all the low-hanging fruit have been feasted upon.) I am not interested in why it cannot be done. There are a million people willing to point to the sound reasons why it cannot be done. Such answers are not useful.

  • How complex of a daemon should be run through inetd?

    - by amphetamachine
    What is the general rule for which daemons should be started up through inetd? Currently, on my server, sshd, apache and sendmail are set up to run all the time, where simple *NIX services are set up to be started by inetd. I'm the only one who uses ssh on my computer, and break-in attempts aren't a problem because I have it running on a non-standard port, and my HTTP server gets maybe 5 hits a day that aren't GoogleBot. My question is, what are the benefits vs. the performance hits associated with running a complex daemon like sshd or apache through superserver, and what, if any successes or failures have you had running your own daemons in this manner?

  • Metro Apps on Windows 8 aren't working with static IP behind auth proxy

    - by Kamal
    In Windows 8 Professional, Metro Apps and Windows Update do not work with static IP settings behind authenticated proxy server. They work with DHCP on the same proxy settings (we have DHCP for wifi and static IP for LAN, both using the same proxy server). IE, Chrome and other desktop apps work nicely with both. Metro apps worked with an auth proxy (DHCP only), when I changed their proxy settings from the "edit group policy" option: Start → Settings → Edit Group Policy → Computer Configuration → Administrative Templates → Network Isolation → Internet Proxy for Apps How can I fix this?

  • What Is The Formula for the 3 of 9 Bar Code Alphabet?

    - by Chris Moschini
    Background: 3 of 9 Barcode Alphabet A simple syntax for 3 of 9 bar codes What is the formula behind the alphabet and digits in a 3 of 9 bar code? For example, ASCII has a relatively clear arrangement. Numbers start at 33, capitals at 65, lowercase at 97. From these starting points you can infer the ASCII code for any number or letter. The start point for each range is also a multiple of 32 + 1. Bar codes seem random and lacking sequence. If we use the syntax from the second link, this is the first six characters in 3 of 9: A 100-01 B 010-01 C 110-00 D 001-01 E 101-00 F 011-00 I see no pattern here; what is it? I'm as much interested in the designer's intended pattern behind these as I am in someone devising an algorithm of their own that can give you the above code for a given character based on its sequence. I struggled with where to put this question; is it history, computer science, information science? I chose Programmers because a StackExchange search had the most barcode hits here, and because I wanted to specifically relate it to ASCII to explain what sort of formula/explanation I'm looking for.

  • Loading main javascript on every page? Or breaking it up to relevant pages?

    - by Kyle
    I have a 700kb decompressed JS file which is loaded on every page. Before I had 12 javascript files on each page but to reduce http requests I compressed them all into 1 file. This file is ~130kb gzipped and is served over gzip. However on the local computer it is still unpacked and loaded on every page. Is this a performance issue? I've profiled the javascript with firebug profiler but did not see any issues. The problem/illusion I am facing is there are jquery libraries compressed in that file that are sometimes not used on the current page. For example jquery datatables is 200kb compressed and that is only loaded on 2 of my website pages. Another is jqplot and that is another 200kb. I now have 400kb of excess code that isn't executed on 80% of the pages. Should I leave everything in 1 file? Should I take out the jquery libraries and load only relevant JS on the current page?

  • WCF WebService: Client can't connect, as soon as request client cerficate is activated.

    - by Hinek
    I have an .NET 3.5 WCF WebService hostet in IIS 6 and using a SSL certificate. The communication between client and server works. Then I activate "request client certificate" and the client can't connect anymore Exception: System.ServiceModel.Security.SecurityNegotiationException: Could not establish secure channel for SSL/TLS with authority 'polizei-bv.stadt.hamburg.de'. Inner Exception: System.Net.WebException: The request was aborted: Could not create SSL/TLS secure channel. The certificate, the client uses is in the certificate store (local computer), the root ca is int the trusted root certification authorities store. Where can I check for an explanation on the server side? How can I check if the client really supplies it's certificate (client is not on my side)?

  • nautilus crash when merging/overwriting files

    - by sBlatt
    On my Ubuntu 10.10, whenever I want to copy some files/folders over some other files/folders, or when I try to empty the trash, nautilus crashes! Example: I have a folder with some files. Now I want to overwrite this folder with a folder with the same name, same files, but some additional files, the merge window comes up, I choose merge and nautilus crashes (does not respond, when I press the close button I can force close it). Some times it even does the copying/emptying (trash), but it always crashes! This happens when copying to the same partition/ntfs partition/netshares, but not when I make a new folder and copy the files/folders into that (without overwriting anything). On a netshare, it's even possible to merge these files afterwards with another computer! dmesg/syslog/messages does not show any entry related to that problem. Does anyone have a solution for this very annoying problem? EDIT: dpkg -l nautilus* (see output in pastebin) EDIT2: I found out, nautilus already crashes before clicking replace/merge (as soon as the question appeares. In the video it's not entirely clear, that i click the cross before the force-close dialog appeares.

  • Do most "normal" people use metro or desktop in Windows 8

    - by ihateapps
    Just curious since I don't fit the definition of a "normal" computer user nor have my friends or relatives upgraded to Windows 8 yet. Are most people in the "wild" (i.e. the "guy in starbucks" or "your friend who works as an auto tech". not you since you are on SU) using metro apps regularly to the point where the desktop is pointless or are they sticking with the desktop? I've gotten mixed statistics from Google. I'm asking for your personal anecdotal opinion based on what you notice in the wild.

You have suggested deleting the lock files in my profile, but, I don't have a profile. I was trying to fix the problem in question http://superuser.com/questions/3275/firefox-on-mac-slow-slow-slow by deleting my profile, so I deleted it, and this came up. So I cannot delete the lock files because they don't exist.

  • How often is your "Go-To" language the same as your favorite??

    - by K-RAN
    I know that there's already a question asking for your favorite programming language here. I'm curious though, what's your go-to language? The two can be very different. For example, I love Haskell. I learned it this past semester and I fell in love with it's very concise solutions and awesome syntax (I love theoretical math so something like fib = 1 : 1 : [ f | f <- zipWith (+) fibSeq (tail fibSeq)] makes my inner mathematician and computer scientist jump with joy!). However, the majority of my projects for classes and jobs have been in C/C++ & Java. As a result, most of the time when I'm testing something like an algorithm or Data Structure I go straight to C++. What about you guys? What languages do you love and why? What about your go-to language? What language do you use most often to get things done for work or personal projects and why? How often does a language fall into both categories??

  • How do i get a more recent version of Java on my Mac than is showing up in software update?

    - by Cd Lolly
    I need at least Java 1.6 to run a program that someone else in my lab wrote On the Java website it tells me to update Java via apple's software update function, i've run this a few times but it only got up to Java 1.5.0_24 and it now says no more updates are available for my computer Is there another way to update Java on a Mac? Is my operating system maybe to old for Java 1.6? i'm not sure what i'm running exactly, and i can't find a list of what mac operating systems run what versions of Java because the java site just suggests using Mac's software update.

  • Scheduled task based on Microsoft patch release cycle

    - by floyd
    I have a simple powershell script which unapproves all patches based on computer group name in WSUS which works great. All of our servers patch on a specific Day/Week/Time starting on Week0-Wednesday which would be the Wednesday after Microsoft Patch Tuesday (2nd Tuesday of every month) all the way to Week3-Sunday. This obviously causes problems as sometimes not all patches get applied in one reboot cycle, and then will install patches the following week during their group policy scheduled patching day/time which is what I'm trying to prevent. My question is I'm trying to schedule my script to run based on this schedule and I am finding it next to impossible using Windows Task Scheduler. For instance if I wanted something to always run on the 4th Monday after Microsoft Patch Tuesday, I cant always use the task scheduler option "4th Monday of the Month" Has anyone run into a similar situation, or know of any task scheduling tools which give you more flexibility than Windows Task Scheduler?
