• What can cause a black or blank screen when pressing logout or switch user in windows 7

  - by Medran

  The situation I have here is related to a brand new dell machine with a GTX260 video card. Put simply after one user logs in when that user either 'switch users' or 'logs out' windows goes to a black/blank screen. The TV screen that is used with this computer previously functioned fine with fast user switching on an XP machine. The new computer is windows 7. The TV is not outputting any error messages like 'no signal' or anything else that would be displayed if the computer was off. You can fix the problem by cycling the input on television, after cycling the input the welcome screen appears as normal. What I want to know is what on earth is windows doing that would cause the video card to stop sending the same signal to the monitor when the user logs off or switches users. I mean as far as I can tell the resolution is identical between windows and the welcome screen. Or perhaps if somebody has experienced this before a fix would be great too.

• Desktop in Kubuntu lacks bars and quite everything after trying to apply Plymouth fix for proprietary drivers

  - by Michcioperz

  I'm running Kubuntu 13.10, my computer's graphics card is Nvidia GT 520. I tried to fix that Plymouth's problem with proprietary graphics driver using an old script I found on the internet (it was coded for Natty, now that I think about it I shouldn't have done it). I ran that script and rebooted my computer. First incorrect behaviour I noticed was that Plymouth only displayed its text splash only on 1/4th of the screen, though when I pressed Esc key the logs were displaying correctly. Main problem appeared when I logged in. All my desktop's windows lack menu bar, can't be closed with Alt-F4, and they don't appear on the task bar. I tried fixing it by reinstalling GRUB a few times, purging /etc/grub.d and /boot/grub, but only the text splash issue was fixed. How can I fix that?

• Googling query from anywhere

  - by Shagun

  Some times when I am trying out stuff on my terminal, I get some blockade or some error to resolve which I have to copy the error or last message then open my browser and then Google the query. Is it possible for me that I select the message via mouse and when I right click I get a Google it option as I get when I select some text on a browser? PS : I am not asking how to do Google search via terminal or how to browse web via terminal.These were the results I got when I goggled my question. what I want is something more general. Whenever I select a piece of text I should get a "Google me" option with the right click of my mouse(or maybe with pressing of a key or something). I would prefer that the query takes place in a browser and not in a terminal.

• HP Presario CQ 61-322ER (VV884EA) Wi-Fi hang up!

  - by qgrabber

  I have my new laptop and don't have Windows XP drivers for it. I found that it contains the Broadcom BCM4310 chip, but when I install any Broadcom driver my laptop hangup on installing bcm5*.sys driver. Only power-off button make any effect. After reboot the device list (Device Manager) contains Broadcom WLAN adapter, but it is marked as disabled, for some hardware errror! Also if I disable device before, and install driver - then - all is OK! But when I try to enable it, Windows hang up anyway (no speaker beep, no mouse input, no keyboard input - nothing) What is the solution?

• How to maximise a Single Window across Multiple Monitors?

  - by LePressentiment

  Say I've 3 monitors. I'll instantiate with http://www.texpaste.com/. What would I need for: The leftmost toolbox to be on the leftmost monitor? The center input blank field on the center monitor? The rightmost output display box on the rightmost monitor? Another example with 2 monitors: http://mathb.in/ Analogously, in this case, I'd want: The input blank field for the code on the left monitor? The rightoutput display box on the right monitor?

• Configure firewalld for OpenVPN (server-bridge) in Fedora 20

  - by rsc1975

  I've installed an OpenVPN server (server-bridge) on Fedora 20, but I cannot get it to work. I'm almost sure that It's a firewall issue. I'm trying to connect from an OSX client, but I can connect (just connect to VPN server, without access to anything) before the bridge is configured in server, however once I configure the bridge interface (using this script), then I cannot connect anymore. I've configured it as server-bridge, following these HOW-TOs from Fedora and OpenVPN Ethernet-Bridge. The firewall config is explained using iptables: iptables -A INPUT -i tap0 -j ACCEPT iptables -A INPUT -i br0 -j ACCEPT iptables -A FORWARD -i br0 -j ACCEPT However, in Fedora 20, by default, It's installed firewalld, so, Can anyone tell me the equivalent commands using firewall-cmd ? I read the firewalld guide, but It's not clear to me how to achieve it (I'm a developer, no SysAdmin). I know that I can install iptables, but I want it to work with firewalld.

• Problem with currency formats and big numbers [on hold]

  - by user132750

  I am working on a dollars to euros/euros to dollars converter in C#. I got the formula, $ times 0.73361 = euro, and I have checked Google with the answers. They were right, (1 dollar equals 0.73 euros). However, it stops working properly when the dollar input value is higher than $1363. This is what I get with $1364: $1364 = 1 000,64 €. I don't know what to do, will someone please help me? Thanks. decimal toEuro; Val.doy = "$" + decimal.Parse(richTextBox1.Text); //Ignore this, it's for the output form CultureInfo eu = new CultureInfo("fr-FR"); toEuro = decimal.Parse(richTextBox1.Text.Trim()); toEuro = toEuro * 0.73361m; richTextBox1.Clear(); Val.duh = toEuro.ToString("C2", eu);

• Pitfalls of using a WYSIWYG editor? [closed]

  - by user50849

  I'm interested in reasons for disallowing content editors on medium to large sites, from using various forms of WYSIWYG editors. A common problematic scenario I can think of is that with the use of a WYSIWYG, an editor uploads an image "somewhere" to the file-system, inserts it directly into the text, and publishes the article. Shortly afterwards, someone wants to pull out "The last 10 uploaded images", and display them on the frontpage. Good luck parsing all the content. Taking a look around at some large international online magazines, such as http://www.time.com/, and some local ones, I see that the editors seem to produce articles that are almost only consisting of raw text. Images are usually at the top of the article, and otherwise the most complex content are usually links. What are some common reasons for refusing editors access to WYSIWYG tools?

• comparing two tables [closed]

  - by sza

  I have two identical table ie all the columns are identical and one of the datatype is Text, one is varchar(255) and the rest are int. Lets say the table name is 'AAAAA'. Table AAAAA was processed and backed up earlier this month. Both the tables were storing data and now the second table is only storing data. I need to find unmatching records from the second table (BBBBB) which is storing data right now and add those records to Table AAAAA. Your help will be highly appreciated. I tried to use 'EXCEPT' but it does not support text datatype.

• My monitor constantly changes from DVI-D to HD15

  - by guest

  I noticed this lately, and it's becoming more often. Basically, when I start my PC, my monitor, which is connected with a DVI-D cable (I don't know what it's called), screen switches to the HD15, where HD15 isn't connected at all. Like, input is changed from DVI-D to HD15, therefore it just blacks out, and then goes back... it's not constant, but it's in random time intervals... I can't do anything on my computer because of this. I even tried connecting it with both DVI-D cable and HD15 cable to the processor, but it still sucks. Is there any way I could force my monitor to stay at only one input method? I'm on XP SP3, and this monitor is about 10 or less years old, a Sony model.

• Possible to create "fake" forum (for prototyping) using html, javascript, jquery, css? [closed]

  - by htmlNewbie

  I am trying to figure out if it might be possible to create a small forum without any use of a database and php coding. I have created a small (local and will only be local) webpage with a couple of menus. I have a forum button which will take me to another .html location. Here i would like to create something that looks like a forum and which you somewhat could interact with like a forum, without any database or PHP. I would probably want/need a form with a heading and text input. When i have given some input, i want it to be displayed as a thread, probably on top of the other threads (which will have to be created beforehand). When I refresh the forum will obviously be set to default, without saving what i just entered since I'm not using a database to save any data. So the new posts will not be saved, just displayed, neatly, when submitted. I'm doing this webpage with forum just as a prototype, and that is why it doesn't have to work as a professional forum. :) Would be very thankful for some tips, tricks, ideas or links to helpful threads.

• Decrementing/Incrementing loop variable inside for loop. Is this code smell?

  - by FairDune

  I have to read lines from a text file in sequential order. The file is a custom text format that contains sections. If some sections are out of order, I would like to look for the starting of the next valid section and continue processing. Currently, I have some code that looks like this: for (int currentLineIndex=0; currentLineIndex < lines.Count; currentLineIndex++ ) { //Process section here if( out_of_order_condition ) { currentLineIndex--;//Stay on the same line in the next iteration because this line may be the start of a valid section. continue; } } Is this code smell?

• How to swap or move 2 string in Array? [on hold]

  - by Wisnu Khazefa

  I have a need to convert .csv file to .dat file. In my problem, there are value pairs, with a name attribute (called Fund) and corresponding numeric value. If the input file has a pair whose value is 0, then that pair (Fund and value) is dropped. The output file should have only those pairs (Fund and value) where the value is non-zero. Here is the prototype of my code. public static void Check_Fund(){ String header = "Text1,Text2,Text3,FUND_UALFND_1,FUND_UALPRC_1,FUND_UALFND_2," +"FUND_UALPRC_2,FUND_UALFND_3,FUND_UALPRC_3,FUND_UALFND_4,FUND_UALPRC_4,FUND_UALFND_5,FUND_UALPRC_5,Text4,Text5,Text6,Text7"; String text = "ABC;CDE;EFG;PRMF;0;PRFF;50;PREF;0;PRCF;0;PRMP;50;TAHU;;BAKWAN;SINGKONG"; String[] head; String[] value; String showText = ""; head = header.split(","); value = text.split(";"); String regex = "\\d+"; String[] fund = {"PREF","PRMF","PRFF","PRCF","PRMP","PDFF","PSEF","PSCB","PSMF","PRGC","PREP"}; for(int i = 0; i < value.length; i++){ for(int j=0;j < fund.length; j++){ if(value[i].equals(fund[j]) && value[i+1].matches(regex)){ if(value[i+1].equals("0")){ value[i] = ""; value[i+1] = ""; } } } showText = showText + head[i] +":" + value[i] + System.lineSeparator(); } System.out.println(showText ); } Expected Result Input: FUND_UALFND_1:PRMF FUND_UALPRC_1:0 FUND_UALFND_2:PRFF FUND_UALPRC_2:50 FUND_UALFND_3:PREF FUND_UALPRC_3:0 FUND_UALFND_4:PRCF FUND_UALPRC_4:0 FUND_UALFND_5:PRMP FUND_UALPRC_5:50 Output: FUND_UALFND_1:PRFF FUND_UALPRC_1:50 FUND_UALFND_2:PRMP FUND_UALPRC_2:50 FUND_UALFND_0: FUND_UALPRC_0: FUND_UALFND_0: FUND_UALPRC_0: FUND_UALFND_0: FUND_UALPRC_0:

• Getting URLs from search results

  - by tereško

  After 1 months research I basically give up on getting all URL's from a search results programmatically, I looked at Google Search API to find a way to get millions of search results "URL's" to be specific to a text file or something relative but no success, but I am 100% there must be a way or trick of doing it. Real Question : Is there anyway programmatically or manually I can get 1000+ search results (URLs using search query e.g. "Apple" returns million of results on google and I want as much as possible URLs of them results in a text file) Note : Don't care for any specific search engine or programming language or technique or software or just point me to right direction, but yeah I tried it with google API i can't get more then 100 results at all.

• Parallelize code using CUDA [migrated]

  - by user878944

  If I have a code which takes struct variable as input and manipulate it's elements, how can I parallelize this using CUDA? void BackpropagateLayer(NET* Net, LAYER* Upper, LAYER* Lower) { INT i,j; REAL Out, Err; for (i=1; i<=Lower->Units; i++) { Out = Lower->Output[i]; Err = 0; for (j=1; j<=Upper->Units; j++) { Err += Upper->Weight[j][i] * Upper->Error[j]; } Lower->Error[i] = Net->Gain * Out * (1-Out) * Err; } } Where NET and LAYER are structs defined as: typedef struct { /* A LAYER OF A NET: */ INT Units; /* - number of units in this layer */ REAL* Output; /* - output of ith unit */ REAL* Error; /* - error term of ith unit */ REAL** Weight; /* - connection weights to ith unit */ REAL** WeightSave; /* - saved weights for stopped training */ REAL** dWeight; /* - last weight deltas for momentum */ } LAYER; typedef struct { /* A NET: */ LAYER** Layer; /* - layers of this net */ LAYER* InputLayer; /* - input layer */ LAYER* OutputLayer; /* - output layer */ REAL Alpha; /* - momentum factor */ REAL Eta; /* - learning rate */ REAL Gain; /* - gain of sigmoid function */ REAL Error; /* - total net error */ } NET; What I could think of is to first convert the 2d Weight into 1d. And then send it to kernel to take the product or just use the CUBLAS library. Any suggestions?

• Possible to run system-config-network during %post kickstart?

  - by tore-

  Hello, I'm currently trying to figure out a smart way to set IP, hostname, gateway and DNS settings during a kickstart (with user input during the kickstart). Doing this with firstboot after the install is not acceptable, so this must be done during %post. I've tried to run the system-config-network tool during post in tty6: #!/bin/sh chvt 6 exec < /dev/tty6 > /dev/tty6 /usr/bin/system-config-network-tui This doesn't work since for some reason I'm unable to catch user input. I would prefer to use built in tools to change this during post, rather than write my own bash script to do this, since using the provided tools is less likely to break anything. Does someone done anything like this or similar, and made it work? Thanks
