I have all the command line utils installed, and need to split an existing .zip (or) new file(s) into (50MB) .zip segments in Terminal. i.e. Folder X = 900MB > Create self extracting .zip archive > Split .zip archive into 50MB Segments (i.e. Folder.X.001.zip ) According to the man page here are the commands: Copyright (c) 1990-2008 Info-ZIP - Type 'zip "-L"' for software license. Zip 3.0 (July 5th 2008). Usage: zip [-options] [-b path] [-t mmddyyyy] [-n suffixes] [zipfile list] [-xi list] The default action is to add or replace zipfile entries from list, which can include the special name - to compress standard input. If zipfile and list are omitted, zip compresses stdin to stdout. -f freshen: only changed files -u update: only changed or new files -d delete entries in zipfile -m move into zipfile (delete OS files) -r recurse into directories -j junk (don't record) directory names -0 store only -l c...

I would like to use a movie player that downloads subtitles in the language of my preference automatically. Is there anything like it? And plugins? Answer VLC media player can do this with an integrated addon. The addon, called VLSub, is to be found separately here . It searches and downloads subtitles from opensubtitles.org using the hash of the video currently playing or its title. VLC media player has an addons/extension site: addons.videolan.org . There is to be found another VLC media player addon for subtitles, called Subtitle Finder . It seems a bit deprecated from time to time, while the VLSub is actively supported and updated . How to install extensions in VLC media player: - Put the file in the VLC subfile /lua/extensions, by default: Windows (all users): %ProgramFiles%\VideoLAN\VLC\lua\extensions\ Windows (current user): %APPDATA%\vlc\lua\extensions\ Linux (all users): /usr/lib/vlc/lua/extensions/ Linux (current user): ~/.local/share/vlc/lua/extensions/ Mac OS X (all use...

I am trying to figure out if I can link a .jpg file with an Excel via hyperlink (or in another way). Let me explain a bit more what I an trying to do: Using Excel 2013 : I have a folder with +1000 images, named by EAN code. I have an Excel file with all the EAN codes that I need an image of. I would like to link each image with each cell in an extra column through a hyperlink. Is this possible? I have tried: =HYPERLINK("[Location pathway]\" & A1 & ".[filetype]","Click Here!") I keep getting an error that it can't open the file. Answer Example below - I made a cell with the path and one with the file extension. Then I combined everything in another cell, like =path-cell & EAN-cell & file-type-cell . In D column I set the Hyperlink. You can, of course, hide the rows and columns that you don't need.

My Postfix server was working fine until last days but now, I can't receive emails from outside (I mean with an email of different domain name like gmail for example). I must make notice that I can send email from the server to gmail. From what I have seen, I think that issue may be my iptables rules : # iptables -L Chain INPUT (policy DROP) target prot opt source destination ACCEPT tcp -- anywhere anywhere tcp dpt:ssh ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT all -- anywhere anywhere ACCEPT tcp -- anywhere anywhere tcp dpt:http ACCEPT tcp -- anywhere anywhere tcp dpt:https REJECT tcp -- anywhere anywhere reject-with tcp-reset with the following /etc/iptables/rules.v4 : # Generated by iptables-save v1.4.14 on Tue Jun 28 02:59:45 2016 *filter :INPUT DROP [4:...

Previously my mouse was working fine on Ubuntu 10.04. Now, starting today, it stopped working. I tested with 2 other mice, but it's still not working. The mouse is turning on though, I see the lights on the bottom.

The latest bizarreness of Skype I noticed recently: When there is an unread message and a notification in the systray icon and I doubleclick it, two Skype windows appear. They have the same content. If I click an item, like a recent chat, both windows show the selected chat. They are like mirrors. Both fully functional. The same thing happens when I open the Skype windows by clicking the new message notification (it is Windows 10). I can close one window and continue using the remaining, so unlike other problems this one is not serious at all. Nevertheless comments are welcome. OS: Windows 10 Pro, up to date Skype Desktop App version 8.55.0.131

I have a scheduled task which runs a batch file which does some stuff. I want the batch file to kick off another batch file which runs in user space; i.e. %username% == the currently logged-in user, with user permissions, etc. How can I run a command under the current user, given that the scheduled task runs with SYSTEM permissions? I need this for both Windows XP and Windows 7.

I'm using the newest Ubuntu live CD to restore my Windows partition. After booting my PC from the live CD I have access to the internet and so on but I cant see the NTFS drive. What should I do to mount it?

This is my setup (the relevant parts, anyway): I have port forwarding rules in place (in the Linksys) for all the relevant ports and I've restarted that router multiple times, each time hoping that would be the magic that makes it work. I've tried removing the port forwarding rule and then re-adding it. Still no go. From the laptop, I can access the NAS (QNAP) via ports :80 and :8080 as well as the counter strike server on the Windows 7 box. So I know those forwarding rules work (and, more importantly, that the client bridged dd-wrt isn't interfering with them). I can access the MySQL server in the following ways: auth'd user via phpMyAdmin running on the NAS auth'd user via local client on Windows 7 machine I cannot access the MySQL server from the laptop despite the fact that I have 3306 forwarded to 192.168.1.101 (and I've checked the configured port of the server multiple times; it's 3306). It appears to just time out while trying to connect via: mysql -...

From Wikipedia : I was wondering how to understand the right-down corner of the picture? Are SATA,USB, Ethernet, mouse, keyboard, and serial/parallel ports connected to Southbridge via PCI bus? In other words, are the buses from Southbridge and Super I/O to "Cables and ports leading-off board" PCI buses? Answer Are SATA,USB, Ethernet, mouse, keyboard, and serial/parallel ports connected to Southbridge via PCI bus? I No those items are only connected to the southbridge and super-io chips are the buses from Southbridge and Super I/O to "Cables and ports leading-off board" PCI buses? The lines to "cables and ports ..." are the respective rs232, USB etc types of electrical connection, not PCI

My XML files are showing the unknown programs icon. Why can't I change the icon? I looked it up in the registry, but I found no error.

What are the major differences? Which is more preferable? Are there any OS specific advantages for one over the other?

I'm afraid the answer is "it won't due to new security features", but I'll ask anyway. I have a USB Flash Drive I run Portable Applications on (who doesn't, right?). I use PStart to start up a nice menu I've been using for a couple years, have my configuration dialed in to something that is productive, so I'm not inclined to just switch to another program. I have an Autorun.inf in the root of the drive. Its contents: [Autorun] Open=Applications\pstart\PStart.exe Action=Start PortableApps Icon=Applications\PortableAppsMenu\PortableAppsMenu.exe Label=PortableApps When I insert the device on Windows 7, I get prompted to choose from a variety of autostart things I don't want to do: It worked fine on XP and Vista, on inserting the PStart.exe would start up and I have menu. Answer Unfortunately, you're correct. The new security features of Windows 7 will not run autorun programs unless it's on optical media. See more here: AutoRun changes in W...

I have two 2560x1440 monitors running off an ATI Radeon 6970 on Windows 7. Before reformatting, I had adjusted the DPI to 120 via Control Panel > Appearance and Personalization > Display > "Medium - 125%". I am not entirely sure, but I think I had checked "Use Windows XP style DPI scaling" (which is the default for DPI less than 144 I believe). My apps looked fine; the text size was larger, but it never really caused any problems. However, upon reformatting, I tried to do the same thing and have ended up with messed up text and icons in my apps. Examples: In Outlook, the icons are resized in crazy ways and look much worse, and the text--- except for the actual message list ---is oversized. In muTorrent, the text is too large to fit in its bounding boxes, and gets clipped. I have tried right-clicking on the program and choosing Properties > Compatibility > Disable display scaling on high DPI settings; this does nothing . Also of note: in Windows Explor...

Background - I'm trying to bulk download some videos from a website. I have all the links and while I can manually open the .bat file and paste the link (and repeat), I was wondering if there is a way to automate this so I could perhaps paste the set of links I have and either have it download continuously (so finish one and move on to the next) or any other automated way? Here is the current script in the .bat file -- @ echo off call set /p link=paste the link: rem call set folder="%~dp0\videos\\" set folder=M:\\Voot If Not Exist %folder% MD %folder% rem call set /p quality=write quality (write low medium or high): Set quality=high call set livestreamer="%~dp0\tools\livestreamer\\" call "%~dp0\tools\php5.4\php.exe" voot.php "%%link%%" "%%folder%%" "%%livestreamer%%" "%%quality%%" :end1 pause :end Here are three links from the site: http://www.voot.com/shows/naagin/1/359115/yaminis-truth-is-revealed/393087 http:/...

I need it every 2 minutes: I am using Debian (text mode only). Answer Assuming you don't want individual tags for total , used , free shared etc, you can wrap the whole output in enclosing tags, as appropriate: XML The following script could be saved as (eg) memoryinfo-xml.sh : #!/bin/bash # memoryinfo-xml.sh - wrap output of free + vmstat in XML tags echo " " echo -e "\t $(date) " echo -e "\t $(free) " echo -e "\t $(vmstat) " echo " " example output: Thu 30 Mar 16:21:18 BST 2017 total used free shared buffers cached Mem: 3853532 3721596 131936 100868 227652 3024584 -/+ buffers/cache: 469360 3384172 Swap: 1182716 2512 1180204 procs -----------memory---------- ---swap-- -----io---- -system-- ------cpu----- r b swpd free ...

When I use 2 monitors, one on VGA and one on hdmi, Win 7 will always assign the hdmi monitor as 1 and the VGA monitor as 2. How can I manually assign these?

Due to a misconfiguration, I have over 1700 failed builds in a Jenkins job. How can I efficiently clean them? Answer You have several options: Temporarily set the number of builds to keep in the job configuration ( Discard Old Builds ) so that those builds will be deleted when the next build finishes. If the next build is 1800, set it to keep the most recent 85 or so. Mark all older builds (i.e. 1 to 10) as Keep This Build Forever before starting the next build. This option will fail to delete some builds if you have a downstream job that prevents upstream builds from being deleted (not a problem in your situation if all of them failed though). Use the Script Console in Manage Jenkins . If it's a top level job (not in a folder), the following will do the trick: Jenkins.instance.getItemByFullName('JobName').builds.findAll { it.number > 10 && it.number Of course, this approach generally requires good backups. There's a lot you can break using the script con...

I would like to save a Word 2010 file so that it has automatically saves a thumbnail image of the first page . These instructions mention how to get Word 2003 to save a thumbnail in the metadata of the .doc file: To save a thumbnail in Word or Excel you must go to File > Properties and select the Save preview picture checkbox. However, Word 2010 doesn't have " File > Properties " and under " File > Options " und both Save and General I find no checkbox called "Save preview". How can I get Word 2010 to save a thumbnail image of the first page of the document in its metadata, to be read out by other applications? Answer This article provides step by step visual details on how to save a word document with a thumbnail: Word 2010: Save Documents to Display with Thumbnail Picture. If you wish to save thumbnails for all word documents by default, follow the steps given below: Go to File > Info then on the right hand side of the screen cl...

I'm using a Vostro 1200 laptop with the Mobile Intel(R) 965 Express Chipset powering its graphics and running Vista 32-bit SP2. I've been using the Vostro with a Dell SE198WFP LCD Monitor as the external display since day one for about two years without any problems. Recently, I plugged the Vostro into a couple of other monitors. The problem is, now the native resolution for my main monitor's (the SE198WFP) resolution of 1440x900 @ 60 Hz is no longer available. (See below) I've tried everything from uninstalling and reinstalling the Intel drivers as well as the monitor drivers to no avail. I've goggled this problem and it appears that this has happened to other people but all the answers involve people giving up in frustration or reinstalling; both terrible outcomes. Has anybody ever figured why this happens and have a good solution? UPDATE: This dude has a complicated solution , which I haven't tried yet. His explanations for the problem was After an exausting ...

To preface my inquiry, I posed a question to the community 3 weeks ago regarding choosing replacement computers for my office of 60 users and had an amazing response. I ended up purchasing 60 HP Business class workstations that I'm really happy with thus far. I'm hoping to get some insight into the processes that others use to clone indentical computers. The specifics are as follows: I have 60 identical Windows 7 machines that will be replacing the current machines within my office. I want to create 60 identical computers with the same Windows 7 configuration, software and settings. These new machines have unique keys (Office 2010, Windows 7) as I don't have a site license with 7. I've looked into some open source and licensed cloning tools (Acronis, Symantec Ghost, Clonezilla, etc.) but I would like to hear some feedback from the community regarding recommendations. Is there a tool in which I can setup one drive as master and clone the other 59? Is it possible to chang...

I have 2 wireless network adapters - internal and external, so I want to create hotspot on second one while using 1st one for wireless connection. Apart from Connectify software. Answer I Figured it out using CMD and providing a small tut so that others can benefit:- 1.To create a virtual WLAN network (HotSpot) enter in Elevated CMD: netsh wlan set hostednetwork mode=allow ssid=yourhotspotname key=YourPassword 2. Then start the HotSpot by giving the following command: netsh wlan start hostednetwork 3. Go to Adapter settings>choose wifi(external/internal which is connected to Internet)>properties>sharing>tick on allow other network and select newly created virtual adapter(with asterisk sign). 4. Hotspot is now online, to stop it enter in CMD: netsh wlan stop hostednetwork 5. Turning the computer off or rebooting also turns the HotSpot off. However, the HotSpot still exists (it "survives" the reboot); from now on you only need to turn it on when needed with the ne...

I have certain applications set to open in certain spaces, but would like them to open in the background and not switch the space just so I can watch them open.

Possible Duplicate: Can you zip a file from the command prompt using ONLY Windows' built-in capability to zip files? Is there a way to zip a file (or group of files) from the command line using Windows 2003? I'd prefer to use built-in commands if possible. Answer I'm not sure it's possible to do it from the command line using only built-in commands. But you can use 7-Zip from the command line; the great thing about 7-Zip is that it's free and open-source. Here 's a quick tutorial on using the 7-Zip CLI. Hope this helps you out!

I was looking at coreutils and found this as one of the files included as part of coreutils: /usr/bin/[ . What is [ and what does it do? It is an executable. I just don't know what it does or how to use it. $ file /usr/bin/[ /usr/bin/[: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, stripped When I try to run it, I think it is defaulting to the bash built in line expansion. Instead of actually running the file. $ "/usr/bin/[" /usr/bin/[: missing ]' $ /usr/bin/\[ /usr/bin/[: missing ]' Answer It's an equivalent of the command test . (See info test .) Generally you use it in scripts in conditional expressions like: if [ -n "$1" ]; then echo $1 fi The closing bracket is required to enclose the conditional. (Well, it looks like its required just to look nicer in the code. Does anybody know any other practical reason for it?)

Installing Windows on a new machine is really painful when it also requires you to re-install all your applications and re-configure all the other miscellaneous details. Are there any applications that can automatically install all your required software on a new install of windows? I imagine that the hypothetical application would need some sort of script and a folder containing all the installers for the software you require. The application would load the script and run all the individual installers with your specified configuration settings. Setting the whole thing up to run the first time would be really quite tedious. But once setup, you could run the application and have your new computer setup with all software and environment settings. One advantage the hypothetical application would have over system backup software is that you would be running a 'clean' install of windows. Over time windows gets a little cluttered with junk leftover from dud pieces of software that ar...

I have an old Vista box sitting around, and I'm thinking of upgrading it to Windows 7 64-bit, as it has 4gb of RAM. Well, I know that there's an "in-place" upgrade from Vista, but does it work from 32-bit to 64-bit? Answer Nope Windows 32bit to 64bit has never been supported. If you are a fan and trust upgrading, you may want to take a look at "Windows Easy Transfer". This should allow you to move your accounts, documents, settings and a whole lot more to a temporary location whilst you can do a full install of the new Windows, then move all your stuff back. From Microsoft 32-bit and 64-bit Windows: frequently asked questions Can I upgrade from a 32-bit version of Windows to a 64-bit version of Windows? No. If you are currently running a 32-bit version of Windows, you can only perform an upgrade to another 32-bit version of Windows. Similarly, if you are running a 64-bit version of Windows Vista, you can only perform an upgrade to another 64-bit version of...

I'm using VirtualBox on Windows 7 to run Fedora 7. I seem to have my SSH on, as /sbin/service sshd status tells me.

I'm my boss' personal help desk, but that's another story... He has this consistent problem where he'll create an Outlook 2007 email (HTML format is the default), and while composing it, happily typing away in the email body, he'll suddenly lose the ability to add, edit, or delete text in the body, or set focus anywhere in the body of the email. The email acts just like a sent or received email in that it is not editable. He thinks maybe he hits an errant key or two when this happens, but I can't find any keyboard shortcut that would cause this issue. Ctrl-Enter would send the email, but it doesn't get sent, so that's not it. If he saves it as a draft and re-opens it, it's still not editable. His workaround is to then send it to himself, open it, copy and paste into a new email, and finish his composition/editing. This makes him grumpy, understandably. Any ideas? TIA

Strange problem. I have a huge Eclipse-based application that frequently spawns copy of its self. On each copy launch there is mouse and sound lags, overall responsiveness of a system is just terrible for 5-10 seconds. There is no such thing with other apps, no matter native, Java or .NET, but every Eclipse-based app I have tried gives that effect. The machine is a little outdated (E8400, 4 GB, 9800 GTX+), but it handles everything I need pretty fast except Eclipse, even my laptop that is much slower in overall handles it well. There is no notable saturation in CPU, disk or memory usage. What can I do with it, guys? Answer I have same issues (AMD Athlon II X3, Intel x25M SSD, 8Gb RAM) same lags with different jdks (from 1.6.09 to 1.7.21) the only workaround I found is to reduce the priority of the eclipse process to "Below normal" from "Normal" before choosing worspace

When I run Palm Desktop as a user other than the one who installed the application it shows "Error: invalid configuration", "Terminating the Palm Desktop", then quits. Same result when running as Administrator. One site I found says Palm Desktop must be installed separately by each user who intends to run it. This sounds redundant, plus I don't have the installer handy. I'm running Windows 10 Pro 1809. I installed Palm Desktop before upgrading from Windows 8 (maybe Windows XP?).

Answer The reaseon was "Hardware reservd operation memory" had 1280mb of 2gb there are some ways to solve this problem. 1)to change boot config "msconfig" 2)to enable\disable RAM mapping in bios 3)to restore system from archive

I am assembling file server for home use. I wonder if it is possible to use multiple disks in a way that they will be visible in network as one continuous space? More less like JBOD. I am using SATA disks, NTFS formatted. Can I achieve this by symbolic links? I mean setting up links from 4 disks to one folder that is sheared? Or there is some way to mach all 4 disks with JBOD on system level and expose this space to the network? Can I setup JBOD when two disks are on different controller than other two? Additional info: Platform: D945GCLF2 + Atom 330 + 2GB RAM System: Win2008R2 Server on ATA disk Storage: 4x1TB SATA disks (2 disks on onboard controller, 2 disks on PCI controller) Usage: Usually one user reading/writing data, basic access rights model (like one from Windows) is ok. Note: I would prefer to stick with Windows+NTFS rather then using FreeNAS+ZFS. Update: After reading all answers and comments I decided to use Dynamic Disks and go with Raid 5. The reason why I decided this i...

I am running Windows 8. Suddenly one day I got an error that C:\ is low on disk space. After doing lot of analysis found that every minute 4-5 log files are being written into Temp folder. File name is like "MSI1d567.log". Googled but did not get any answers. How do I stop the errors.

I'm using a 17" TFT at 1280x1024 at home and work. I'm also using 14" TFT at 1024x768. What is the least stresfull distance for the eye to work with it? What is the general connection between screen size, resolution and viewing distance? Some kind of a formula? Do you know of any research papers on that topic? Answer I'd say that the optimum distance depends greatly on the watcher. One should use a distance that feels comfortable. There exists quite a few HDTV distance calculators in the net but they, as their name suggests, are mainly targeted to TVs and to screen sizes of 22" and up. The rule of thumb with smaller screens used to be that you should sit an arm's length from the screen. Some scientific sources - more or less - are listed e.g. in Wikipedia's HDTV viewing distance article .

I just installed Google Chrome on my Mac at work, and used it for browsing the entire day. Among other things I went looking for an adblocker, which I found. When I got back home and did the same search, the links for that adblocker were styled as visited, even though I hadn't searched for it at home before. Does Google Chrome sync history between computers without even asking? I checked the preferences but sync is not set up on my home or my work computer. Answer Chrome does sync History now. Google does keep a track of previous searches, when you're logged into your account.

I'd like to use three screens. I've looked on Google and found a lot of different and contradicting answers, so I decided to post a question. What I have now: three screens, and an NVIDIA GeForce GTX 460 with 2 DVI ports and 1 HDMI port. I think that just linking the HDMI port to another screen won't work, and I've found a lot of solutions, but I'd like to hear the best and cheapest way to get it done. I also have an old NVIDIA GeForce 8600 GT. Could I use that to send the signal, but let the 460 GTX do any calculations? Or perhaps it's possible to let Windows/the card think the three screens are one screen, so it's only really rendering one big image that can be split somehow?
