• Windows 7: Creating a password-protected task (NOT a programming question)

  - by Matthias

  Hello, I would like to configure a task like "child control software", so it would hibernate the pc at certain times. Is it possible to prevent modification (here: pausing) of a task through requiring the entering of the admin password to modify, EVEN THOUGH the currently-logged-in (and only) user is the admin account itself? (Do you know of any child control software that does NOT require an additional account yet is able to hibernate the system at certain times?) Thanks a lot! Matthias

• Why doesn't this for loop work?

  - by evilsoup

  This is on Ubuntu 12.04 I'm trying to figure out how to get ffmpeg to do a batch conversion of FLACs to MP3, recursively. If I cd into a directory and use for f in *.flac; do ffmpeg -i "$f" -c:a libmp3lame -q:a 2 "${f/%flac/mp3}"; done that works perfectly fine. However, when I try this, it doesn't work: for f in "$(find . -type f -name *.flac)"; do ffmpeg -i "$f" -c:a libmp3lame -q:a 2 "${f/%flac/mp3}"; done It doesn't even throw up any useful errors (but here is the output anyway, no need to complain): evilsoup@enchantment:~/Music/Jean Sibelius$ for f in "$(find . -type f -name *.flac)"; do ffmpeg -i "$f" -c:a libmp3lame -q:a 2 "${f/%flac/mp3}"; done ffmpeg version git-2012-12-18-b7e085a Copyright (c) 2000-2012 the FFmpeg developers built on Dec 18 2012 19:23:11 with gcc 4.6 (Ubuntu/Linaro 4.6.3-1ubuntu5) configuration: --enable-gpl --enable-libfaac --enable-libfdk-aac --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-librtmp --enable-libtheora --enable-libvorbis --enable-libvpx --enable-x11grab --enable-libx264 --enable-nonfree --enable-version3 libavutil 52. 12.100 / 52. 12.100 libavcodec 54. 80.100 / 54. 80.100 libavformat 54. 49.102 / 54. 49.102 libavdevice 54. 3.102 / 54. 3.102 libavfilter 3. 28.100 / 3. 28.100 libswscale 2. 1.103 / 2. 1.103 libswresample 0. 17.102 / 0. 17.102 libpostproc 52. 2.100 / 52. 2.100 ./Symphonies 1, 2, 3 & 5 (Oslo Philharmonic Orchestra Conducted by Mariss Jansons) Disc 1/02.

• Core i7 on linux loses its multithreading capability after suspend

  - by rafak

  On my debian-linux system, with a core i7 920 , each time I resume after the command "pm-suspend" (suspend to RAM), mutlithreading capabilities almost disappear. More specifically, two distinct programs can use 2 distinct cores at full rate, but a single program is limited to only one core (for one instance of a multithreaded program as well as multiple instances of a monothreaded program, e.g. "make -j 4" for gcc). So I end up rebooting the system. Any help appreciated!

• CentOS running inside VMware as WebServer times out on outside connection

  - by Tom Hart

  I have a CentOS machine running inside VMware, and I have got PHP and Apache set up on it, so if I open a browser (on the VM) and go to either localhost, or 192.168.0.3, I get a phpinfo page I made in /var/www/html/index.php, but, if on the host (Windows 7), in my browser I go to 192.168.0.3, it times out. I can ping the IP address from Windows and get a response, I just can't through the browser. Does anyone have any ideas what I need to do to get this working? This is my first time using a VM and I'm getting lost in the network settings.

• How can I dual boot a UEFI OS and a legacy boot OS, or convert stock Windows 8 to BIOS?

  - by The Great Widi

  I have a computer (HP Pavilion g6-2342dx) which came with Windows 8, and thus the new UEFI boot system. I would like to install a few OS's which are not EFI compatible, and Arch GNU/Linux with BIOS mode. However, I would not like to completely wipe all my files to set to legacy. My preferred options would be to: 1. Multiboot legacy OS alongside my EFI os 2. Convert Windows 8 and Ubuntu to legacy without reformatting or switching to MSDOS part table. If anyone could suggest a solution or a method, your help would be appreciated! Thanks!

• Why Both 8GB USB Flash Drives Have Different Integrities?

  - by Boris_yo

  USB 3.0 SuperTalent Express DUO 8GB recently had its partition corrupted and declared itself "write-protected" and I was told in chat by @sidran32 that this usually means that flash drive gone bad due to writing cycles limit being reached. Having this thumbdrive for over a year being used infrequently, I was in doubt and referred to SuperTalent's support. I was given recovery tool which I executed but it failed first time prompting me to reinsert it. After that, I formatted it with Windows 7 integrated format utility since recovery tool offered to do this as well which was successful. The problem as I have noticed is with integrity of SuperTalent: Compare above to SanDisk's Micro Cruzer 8GB: Am I missing something? Both thumbdrives are of 8GB and have same FAT32 file system.

• IIS8 behind a VPN + Windows Server 2012 - how to properly bind IP+Port

  - by ryugen

  This is my first question so I hope I'm going to give you enough information. I'm running Windows Server 2012 within the Hyper-V environment of my Windows 8 machine. Within Windows Server 2012 I'm running a VPN tool based on openVPN to hide my real IP. When I run IIS8 with the VPN disconnected it works flawlessly through the Internet (port 80 forwarded correctly). But as soon as I connect to the VPN I can't reach my site through the domain anymore. Now I tried basically everything I know which is why I'm asking you guys. I tried binding IIS8 to the IP of my virtual ethernet card. I tried changing the priority of the NIC through the "Network and sharing center" via the advanced tab. I used ipconfig /flushdns in case there was something wrong in the DNS handling. Hell, I even turned off the Windows firewall. I also used a port scanner to verify the problem. The webserver is reachable on port 80 with VPN disconnected and immediately gets unreachable on connect. Theoretically both IPs (my regular one AND the VPN) should be reachable or at least not impair the other one right? Do you have any other suggestion? Do I have to route something somewhere somehow?

• Windows and Linux applications to show cumulative uploads/downloads for each app, at a glance

  - by jontyc

  I've read few quite a few other threads on SU, but they have been focused on instantaneous/average bandwidths (B/sec) rather than cumulative download/upload totals for a period. Either that or they don't drill down to application level. Resource Monitor in Windows 7 only shows bandwidth. I've just been trying NetLimiter and whereas it can show total uploaded/downloaded, it's a case of having one stats window open per application, as opposed to a table showing all applications at once. Looking for applications for both Windows and Linux (Ubuntu), but they don't need to be the same.

• VLOOKUP and match functions appear to be searching the function rather than value

  - by Brandon S.

  Vlookup and match seem to be searching based on the function I have in my cell rather than the value i have in the cell. I have a column with dates, (ex: C2, which has the formula =E2&"/"&F2&"/"&D2 in them, for example). (where E2, F2, D2 are the year, month, and date). In another sheet and column, I have a bunch of dates, and i'm using the formula =VLOOKUP(C2,'sheet2'!A1:B252,2,FALSE), which doesn't work. (returns #N/A) If I replace C2 with the same date, but without the formula (just typing it in), VLOOKUP works. Why is this?

• Find and hide file extension

  - by Daveo

  I am trying to find all files that have the same filename (excluding the file extension) that occur 3 times. I also need the full path to the file. What I have currently is #get file without extension alias lse="ls -1R | sed -e 's/\.[a-zA-Z]*$//'" #print out the current dir and get files occuring 3 times lse | sed "s;^;`pwd`/;" | sort | uniq -c | grep " 3 " This runs howver pwd prints the folder I ran the command from not the path to the file. So I tried find find . -type f | sed "s#^.#$(pwd)#" | sort | uniq -c This runs but includes the file extension. When I try to add sed -e 's/\.[a-zA-Z]*$//'" I get errors as I am not sure how to combine the two sed commands and I cannot seem to pipe a second time to sed? so what I am trying to do is find . -type f | sed "s#^.#$(pwd)#" | sed -e 's/\.[a-zA-Z]*$//'"| sort | uniq -c | grep " 3 " but this does not run.

• light text editor for csv file? (on windows)

  - by Radek

  could anybody suggest a light (small, fast) text editor that can handle columnar view of csv files? save quote character to all fields, even if not 'necessary' OpenOffice Calc is bit big for my old laptop. My favourite Notepad++ cannot do the columnar view. And it seems to me that Sharp Tools Spreadsheet cannot import csv file. GoogleDoc convert some date fields by default which I do not want and it is really not fast and easy way how to edit csv.

• Windows 7 Change internet time settings tells me I have no permissions.

  - by Matthias Vance

  LS, While trying to solve my computer clock always running ahead (even when on, not just on every boot), I apparently broke some security settings. All I did (as far as I can remember) was stop and start the w32time service. Now, whenever I go to the "Internet time" tab, and click "Change settings..." Windows tells me I don't have permissions to do so. Facts I am a member of the Administrators group. In gpedit.msc, I checked that the Administrators group is allowed to change the system time. Kind regards, Matthias Vance

• Make dhcp assign same IP and hostname for different interfaces at one machine

  - by Egeshi

  I have a feeling that question itself looks stupid but it is not. Please let me clarify. I have dynamic DNS with BIND and NIS configured at my LAN and have laptop which I am using in both wireless and wired mode. I mean that sometimes I have to use wired interface to achieve higher throughput but most of time I don't need it and using wireless mode. Everything works great. Issue is that I want both interfaces get same IP from DHCP. Just for convenient firewall setup. If I add both hosts to dhcp in this manner # bt wireless host bt { hardware ethernet 00:1f:1f:62:60:28; fixed-address 172.16.77.110; } # bt wired host bt { hardware ethernet 00:14:22:b7:5a:de; fixed-address 172.16.77.110; } DHCP says logs following message dhcpd: Dynamic and static leases present for 172.16.77.110 dhcpd: Remove host declaration bt-wired or remove 172.16.77.110 dhcpd: from the dynamic address pool for 172.16/16 Host records are added outside of any subnet, but it makes no difference if I put them there, effect is still the same. This is not critical but either is not my whim because even if DHCP seems to work fine for that "bt" host, I cannot make connection TO it from remote machine anymore with this definitely incorrect DHCP config. I'd be thankful if one spares a minute for advice about how to configure DHCPD correctly. UPDATE. I realize that there's a soulution to assign different hostname in DHCP config but would like to use benefits of short host names.

• laptop headphone jack problems

  - by Xitcod13

  A while back my headphones mysteriously started making static noise and one of them stopped working completely. At first I thought it was headphones so I bought new ones. Alas that did not solve the problem. The problem must be inside my headphone jack. I did some research online and they suggested unplugging USB devices. Which has a strange effect of changing the static noises to high frequency Morse code noises (it's the aliens). I don't have this problem when i listen to music on speakers. The static is there on headphones whether there is music or not. I own a soldering iron for electronics and I am quite skilled at soldering. I would appreciate any help I can get. My laptop is the HDX 18. It has 2 headphone jacks that act exactly the same. Interesting thing i just noticed is that when i pull out my headphones almost all the way both of them start working but so do the speakers making the headphones kinda useless. Maybe there is a way to turn of the speakers as a temporary solution. I am using vista x64.

• Picasa "sync to web" folders losing sync when they are moved

  - by GJ.

  I've been using the Picasa "sync to web" feature but recently noticed that several folders, with a lot of synced photos and videos inside them, lost their synced status as soon as I moved them to another location on the disk (not through the Picasa "move folder" command). These folders now still appear with the green arrow indicating that their contents were uploaded, but they lost the blue sync icon they previously had (and are no longer syncing...). If I try to reactivate the "sync to web" option for these folders, Picasa starts re-uploading ALL of their contents. This is absurd.. and would take ages to complete. Is there any way I can somehow get Picasa to recognize these moved folders as the counterpart folder of an existing online folder for sync purposes?

• Corrupt file indicative of corrupt hard drive?

  - by Elipsicon

  I have noticed that two files on my (almost full) 2 TB hard drive have been corrupted. One file has 20 kB (!) corrupted, i.e. consecutive 20 kB have changed, even though the modification date of the file hasn't changed and I haven't worked with this file for over a year. This tells me that something "below" the file system level has messed with the data and the only thing I can think of is hardware failure, most likely hard disk failure. I've tested my RAM already and it works flawlessly. I'm using ext4 on Linux, if that is of any help. Is this normal? Is it time to change my hard drive disk before something worse happens? What can I do to prevent that from happening in the future? Is there some built-in feature of, or extension to ext4 that includes additional error correcting code and/or watches files for changes that haven't been caused by the OS?

• Arbitrary Key Remapping on a Mac

  - by Mason

  I bought a cheap Chinese replacement keyboard for my late 2007 MBP. The close square/curly bracket key actually sends a left control signal to the Mac. So I'm trying to remap my backslash/pipe key to be close square/curly bracket but I can't find the key remapping software to do it. Double Command and KeyRemap4Macbook can't do arbitrary key remaps and uControl/fkeys don't work on Snow Leopard. Anyone have ideas? I have no problem editing text config files if necessary.

• Skype Optimization - Port Forwarding on a Router

  - by user19185

  I was watching this Video which talked about using port-forwarding to optimize your LAN for skype calls. According to the video, as explained in the first couple of minutes in the video, the reason you would need optimization is because if the person your call has a firewall setup, your connection has to go-through a third-party computer to connect to them. I believe I stated this correct (maybe not). None the less, my question is this: do both parties on the call need to enable port forwarding to optimize skype, or just one party (person)?

• Quicksilver doesn't open PDF's like it used to

  I've been using Quicksilver for a while now but lately I've been getting this problem that QS doesn't show the Acrobat Reader icon when a PDF is selected, but goes to the "Open With" tab. See the screenshot here: http://skitch.com/niels.bom/n8nw5/google-reader-1000 Is this a bug? Or did I somehow bork a preference setting? I'm using QS B54, 3815, which is the latest AFAIK and Mac OS X 10.5.8. Thanks!

• Vim: Show the index of tabs in the tabline

  - by bitmask

  Lets say I opened file1.txt, file2.txt, file3a.txt and file3b.txt such that the tabline (the thing on the top) looks like this: file1.txt file2.txt 2 file3a.txt (Note how file3b.txt. is missing because it is shown in a split, in the same tab as file3a.txt) To move more quickly between tabs (with <Number>gt), I would like each tab to display its index, along the filename. Like so: 1:<file1.txt> 2:<file2.txt> 3:<2 file3a.txt> The formatting (the angle braces in particular) are optional; I just want the index to appear there (the 1:, 2: and so on). No clues on :h tab-page-commands or google whatsoever.

• Activate Windows XP in VMWare?

  - by Zeno

  Running Windows XP in VMWare, how should activation be handled? Last time I did this, I do not remember having to do any activation. Now it is asking me to activate Windows XP. Am I suppose to buy and use a real WinXP key? What is this about a "Windows XP Mode" I'm hearing about that you can enable in VMware to activate it? The availability of Windows XP Mode is equivalent to a free license to Windows XP operating system. My host machine runs Win7. My goal is to get WinXP running in VMWare the simplest way, but this activation is giving me issues (such as that WinXP doesn't seem to be sold anymore). I Googled around and found that VMWare has a xpmode.enabled = "TRUE" feature which instantly activates Windows XP (with limits, like only once), but I do not know anything about it or how to use it.

• setting up a WGR614v7 behind a linux box

  - by commodore fancypants

  Here's the setup, I have an openSUSE box with 2 NICs, one goes to my home network router, the other has DHCP running and it attached to a wireless router. I'm trying to get this setup to work before I switch to the linux box as my home network router. My DHCP will offer the wireless router (a WGR614v7) an address, but anything that connects to the wireless router ends up with a APIPA address. I have all the firewalls on the wireless network turned off as well as the wireless router's own DHCP. The linux box isn't offering addresses to anything past the wireless router. Is this a problem with the router or my DHCP setup? For testing purposes, I have both NICs set in the internal zone and I've tried wireless and wired connections to the WGR614v7 both to no avail.
