• USB to USB CD ROM emulator

  - by JohnnyLambada

  I'm wondering if anyone knows of a CDROM emulator that runs on Linux. I want to emulate this configuration: [CDROM DRIVE]----USB CABLE----[COMPUTER UNDER TEST] Where [COMPUTER UNDER TEST] is a computer that boots from a physical CD inserted into the [CDROM DRIVE]. Only instead of the [CDROM DRIVE] I want the following configuration: [CD IMAGE BUILD MACHINE]-----USB CABLE-----[COMPUTER UNDER TEST]. I want to build an ISO image on the [CD IMAGE BUILD MACHINE] and have some sort of USB CDROM emulator running on it to serve up the ISO image to the [COMPUTER UNDER TEST] as though it was talking to the [CDROM DRIVE]. Does this exist? If it does, I can't find it. I want to do this so I can test out bootable CDs without burning a lot of coasters.

• Is encryption really needed for having network security? [closed]

  - by Cawas

  I welcome better key-wording here, both on tags and title. I'm trying to conceive a free, open and secure network environment that would work anywhere, from big enterprises to small home networks of just 1 machine. I think since wireless Access Points are the most, if not only, true weak point of a Local Area Network (let's not consider every other security aspect of having internet) there would be basically two points to consider here: Having an open AP for anyone to use the internet through Leaving the whole LAN also open for guests to be able to easily read (only) files on it, and even a place to drop files on Considering these two aspects, once everything is done properly... What's the most secure option between having that, or having just an encrypted password-protected wifi? Of course "both" would seem "more secure". But it shouldn't actually be anything substantial. I've always had the feeling using any kind of the so called "wireless security" methods is actually a bad design. I'm talking mostly about encrypting and pass-phrasing (which are actually two different concepts), since I won't even consider hiding SSID and mac filtering. I understand it's a natural way of thinking. With cable networking nobody can access the network unless they have access to the physical cable, so you're "secure" in the physical way. In a way, encrypting is for wireless what building walls is for the cables. And giving pass-phrases would be adding a door with a key. So, what do you think?

  - by liweijian

  Microsoft do not sell Windows 8's DVD in China, We can only update to Windows 8 from Windows 7 , Vista or Windows XP SP3.

• Chrome's new window disappear from desktop

  - by faulty

  I'm having this problem with Chrome on a Windows 7 x86 machine. I'm using Chrome for a locally hosted intranet web app. In the web app, there's frequent use of new window which popup, which works like a dialog box for the app. The problem started since yesterday. All the new windows doesn't appear on top and no where to be found on the desktop. But it does appear on the taskbar. Clicking the button on the taskbar doesn't bring up the window as well. I've also tried Alt+Space, then Move, it doesn't work. I only found 2 way to bring it up, Maximize or Show as tab. What could have caused this and how should I fix it? Thanks EDIT: I've configure to not group taskbar buttons. EDIT: I've just gone through the javascript of the button, it call window.open to display the popup. I can see the popup flicker and disappear. If I step through the code, the popup will display properly, sometime. Also, if I click the button twice, it will also display the popup, but at a much smaller size, less than 100x100

• Cannot select fields with the mouse Windows 7

  - by Nick

  Lately I cannot select a word (field) with the mouse. When I left click on a field drag the mouse to the end of the field then release the button, the selection (blue shading) disappears. Sometimes after several tries the shading stays and I can delete the field. Up to a week ago everything worked fine. Is this a bug, virus? I am using Windows 7 Also, in Live Mail after I finished reading an item in the Inbox, I click the X in the upper right corner to return to the rest of my mail, but instead it takes me back to the desktop and have to double click the Live Mail again to continue. Again this only happened recently. Things worked OK before and this does not happen regularly.

• Pandoc: Output two sumation signs in equal height in Word 2010

  - by Andy

  I need to output some complex equations in Word 2010 (docx). To do so I write most of the equations in tex and use pandoc to translate them as Word formulas. However I have a problem with the following tex equation: \sum_{m=1}^\infty\sum_{n=1}^\infty In Word the resulting two summation signs are not of the same size but the latter is smaler than the first one. Is there any workaround to solve this? I would deeply appreciate any help. Thank you Andy

• Why do I often have to refresh pages I navigate to once for them (or content in them) to load?

  - by GetOutOfBox

  I have noticed a bizarre pattern when using my PC, that when I open a link to a website, it often will often take a very long time to load, or time out. Sometimes content on the website will be drawn, but again, it seems to get "stuck" for an unusual amount of time before finishing. Most affected is Youtube; almost every time I navigate to a youtube video from another website such as Google, the video will not begin playing, but will instead just display the player controls with a black screen where the video should be and the buffering symbol, usually before displaying an error such as "The video failed to load". The unusual part of this problem is that whenever this happens, refreshing the page always causes it to load almost immediately the second time around, without any problems. Note that I'm not talking about how some browsers will dump whatever has been cached to the "pallet" briefly when the page is refreshed or loading stopped; but that the second time loading the website being faster. I have done my best to rule out some of the obvious causes: My Windows 7 desktop computer is the only device that seems to be affected. I use Firefox on it (latest version, flash updated, etc). My connection has more than enough bandwidth (30 megabits down, 4 up), and I've even tried QoSing all other devices to make sure this isn't happening due to usage spikes. Wireshark is not showing any clearly unusual network activity (i.e frequently dropped packets).

• Unix: Files starting with a dash, -

  - by Svish

  Ok, I have a bunch of files starting with a dash, -. Which is not so good... and I want to rename them. In my particular case I would just like to put a character in front of them. I found the following line that should work, but because of it dash it doesn't: for file in -N*.ext; do mv $file x$file; done If I put an echo in front of the mv I get a bunch of mv -N1.ext x-f1.ext mv -N2.ext x-f2.ext Which is correct, except of course it will think the first filename is options. So when I remove the echo and run it I just get a bunch of mv: illegal option -- N I have tried to change it to for file in -N*.ext; do mv "$file" "x$file"; done but the quotes are just ignored it seems. Tried to use single quotes, but then the variable wasn't expanded... What do I do here? Update: I have now also tried to quote the quotes. Like this: for file in -N*.ext; do mv '"'$file'"' '"'x$file'"'; done And when I echo that, it looks correct, but when I actually run it I just get mv: rename "-N1.ext" to "x-n1.ext":: No such file or directory I have just no clue how to do this now... sigh

• Blade servers in a home

  - by Zubair

  I'm thinking of buying a blade server enclosure I can use at home and just plug in more servers for more power. Does anyone have any experience with this? Also, what sort of prices am I looking at for an enclosure, as I have noticed that Dell doesn't list prices on their site.

• Dealing with AVCHD. Any free software to extract or edit AVCHD video?

  - by Kelsey

  I have a Panasonic HDC-SD5 video carmera which records in HD format to a memory card. It also came with a DVD burner which burns this format to DVD which I need a blu-ray player to view. I can get about 30 min worth of video on 1 DVD. My problem is the software that comes with the camera is not very good at all so I am constantly just using the 'backup' feature in the included burner (connect drive to camera, push backup, and it spits out up to 4 DVDs worth of HD video). Now that I have the video backed up on DVD in the HD format (blu-ray), is there any free software that I can use to edit this video and create other HD DVD's with my own menus, transitions, etc? I was considering buying Pinnacle Studio but I wanted to exaust any free options before biting the bullet. Any suggestions for software I could use or anything else I could do to make dealing with this AVCHD format any easier that I am unaware of? Edit: Sorry forgot to include that I am running Windows Vista 64-bit. Edit: Still haven't found anything that is truely free. Everything has limitations by either time, watermark the video or degrade the quality. Edit: So I still haven't found really anything, so is there some software I can use to convert the video to another format that I then could use to edit the video?

• download management

  - by Jonathan

  I download many files, usually 2 or 3 a day, often 10ish. Some of them are duplicates because I just can't be bothered to find the original in my downloads folder. I have previously tried DAP and used that to create a new subfolder for each day's download. yet I have found this insufficient as sometimes I wish to find files by name/file type or I have multiple parts of downloads over more than one day. Another problem I have found is zips/rars/etc after downloading them and extracting them I then have the zip and the folder. I like it like on a Mac where it automatically extracts the zip after it has been downloaded and removes the zip. What I'd like to be able to do is sort the downloads by date, but dynamically so they are just in the big downloads folder, but I can just press a button and it will show me all the files from a particular site, or from a particular day or by a certain file type. Is there any software that will do this? I use Chrome as a browser but also have Firefox and like that. Jonathan

• Why is Latex so big?

  - by putmatrix

  On windows, MikTex comes in a DVD. It's several times bigger than a typical Linux distribution. This makes it impossible to carry Latex on a memory stick like I do with many other useful software. Why is it so big? I thought it was just a language or system, but I've never seen any programming language with gigabytes of libraries. It's just that there's a bad feeling when your Latex distribution takes up four gigabytes of space when you expect it to be more of, say, 200mb.

• Restoring the exact state of a linux install to a different laptop with different sized drives and other hardware

  - by user259774

  I have an IBM running a Manjaro install that has already been used and settled into, with packages installed, browser profiles, etc, etc. The drive is 60gb, and it has a swap partition and an ext4 root partition. I need to move this profile to a Toshiba computer with a 320gb drive. How should I go about this? My inclination would be to shut down the toshiba, boot a live linux system, dd the whole 60gb drive to a file, boot the toshiba to a live system, then dd the file to its 320gb drive. Would this work? I know that it wouldn't with windows, but I believe this is an artificially imposed limitation from Microsoft. Is this correct, or is Linux similarly limited? If not, how could I go about this? Would clonezilla work, or would the hardware disparities prevent it from working?

• Programs minimized for long time takes long time to "wake up"

  - by bart

  I'm working in Photoshop CS6 and multiple browsers a lot. I'm not using them all at once, so sometimes some applications are minimized to taskbar for hours or days. The problem is, when I try to maximize them from the taskbar - it sometimes takes longer than starting them! Especially Photoshop feels really weird for many seconds after finally showing up, it's slow, unresponsive and even sometimes totally freezes for minute or two. It's not a hardware problem as it's been like that since always on all on my PCs. Would I also notice it after upgrading my HDD to SDD and adding RAM (my main PC holds 4 GB currently)? Could guys with powerful pcs / macs tell me - does it also happen to you? I guess OSes somehow "focus" on active software and move all the resources away from the ones that run, but are not used. Is it possible to somehow set RAM / CPU / HDD priorities or something, for let's say, Photoshop, so it won't slow down after long period of inactivity?

• How can I create an external SSL wrapper/tunnel page for an insecure webpage behind a firewall?

  - by Ross Rogers

  I have an security cam with a built-in webpage inside my home network. That camera is using basic HTTP authentication instead of SSL. I want to be able to access the camera's webpage from outside my network, but I don't want to open an unencrypted video stream to the outside world. Right now, I'm doing some cumbersome ssh tunneling where I bounce off an ssh server like: ssh -N -L 9090:CAMERA_IP:80 [email protected] and then I connect to my web page like: http://localhost:9090 But this is a pain. Now, gentle reader, I beseech you to tell me how I can use linux (Ubuntu) to get a fully encrypted SSL connection to my internal web page without the hassle of creating an ssh tunnel each time. I believe I can use stunnel, but I'm not sure of the command.

• Microsoft signed drivers appears as publisher not verfied

  - by Priyanka Gupta

  Task at hand: Microsoft sign drivers on Win 7. I microsoft signed my driver package 3 times every time thinking I might have missed a step or something. However, I cannot seem to get rid of the Windows Security error message "Windows can't verify the publisher of this driver software'. This is not the first time I have signed the driver packages. I was successfully able to sign other driver packages a few months ago. However, with this driver package I keep getting Windows security dialog box. Here's the procedure I follow - Create a new cat file using INF2CAT tool. Self sign the driver using a Versign Class 3 Public Primary Certification Authority - G5.cer. Run the microsoft tests on DTM Servers and clients with the devices that use this driver. Create WLK submission package. Self sign the cab file. Submit the package for certification. The catalog file that comes back after successfully passing tests says Name of signer "Microsoft Windows Hardware Comptibility Publisher". When I check the validity of signature using SignTool, it says the signature is vaild. However, when I try to install the driver with new signed catalog file the windows complain. Any ideas? Edit 11/12/2012: Reply to Eugene's comment Thanks for the help, Eugene. Yes. I did sign two other driver packages before. One of them was modified version of WinUSB driver. I am using the same certificate I used when I signed those two driver packages a few months ago. It costs $250 per signing from Microsoft. I would think that Microsoft would complain about it during certification if the certificate is wrong. I use the following command to self sign the CAT file. I don't have to specify the ceritificate name as there's only one certificate in the directory - Signtool sign /v /a /n CompanyName /t http://timestamp.verisign.com/scripts/timestamp.dll OurCatalogFile.cat Below is the result from running Verify command on the Microsoft signed OutCatalogFile.cat C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\x64signtool verify /v "C:\User s\logotest\Documents\serialdriversigning\OurCatalogFile.cat" Verifying: C:\Users\logotest\Documents\serialdriversigning\OurCatalogFile.cat" Hash of file (sha1): BDDF39B1DD95881B462164129758A7FFD54F47D9 Signing Certificate Chain: Issued to: Microsoft Root Certificate Authority Issued by: Microsoft Root Certificate Authority Expires: Sun May 09 18:28:13 2021 SHA1 hash: CDD4EEAE6000AC7F40C3802C171E30148030C072 Issued to: Microsoft Windows Hardware Compatibility PCA Issued by: Microsoft Root Certificate Authority Expires: Thu Jun 04 16:15:46 2020 SHA1 hash: 8D42419D8B21E5CF9C3204D0060B19312B96EB78 Issued to: Microsoft Windows Hardware Compatibility Publisher Issued by: Microsoft Windows Hardware Compatibility PCA Expires: Wed Sep 18 18:20:55 2013 SHA1 hash: D94345C032D23404231DD3902F22AB1C2100341E The signature is timestamped: Tue Nov 06 11:26:48 2012 Timestamp Verified by: Issued to: Microsoft Root Authority Issued by: Microsoft Root Authority Expires: Thu Dec 31 02:00:00 2020 SHA1 hash: A43489159A520F0D93D032CCAF37E7FE20A8B419 Issued to: Microsoft Timestamping PCA Issued by: Microsoft Root Authority Expires: Sun Sep 15 02:00:00 2019 SHA1 hash: 3EA99A60058275E0ED83B892A909449F8C33B245 Issued to: Microsoft Time-Stamp Service Issued by: Microsoft Timestamping PCA Expires: Tue Apr 09 16:53:56 2013 SHA1 hash: 1895C2C907E0D7E5C0292B92C6EA8D0E236F525E Successfully verified: C:\Users\logotest\Documents\serialdriversigning\OurCatalogFile.cat" Number of files successfully Verified: 1 Number of warnings: 0 Number of errors: 0 Thank you!

• Certain web pages are suddenly not rendering properly in FireFox

  - by LeopardSkinPillBoxHat

  I am using FireFox 3.6.3. I noticed in the last couple of days that several webpages which I visit regularly are not rendering properly. A lot of the text is overlapping with other text and it basically looks like the style sheet is completely screwed up. I have tried disabling all of my Add-Ons and it doesn't make a difference. When I use Coral IE Tab to render the pages using IE they display without any problems. The websites which are not rending properly for me are: The Age Google Reader One interesting thing I noticed is that if I modify the Google Reader URL to not use SSL (i.e. change https to http) it renders without any issues. However, The Age website is not using SSL, and that still doesn't render properly. I have also disabled my Proxy Server (I normally use one at work) but this doesn't make a difference either.

  Hey guys, I was wondering how to make an hybrid usb stick. That means a usb stick that runs under mac and windows and displays specific content. Example: Plug in on win : index.html opens. Mac os X files are invisible. Plug in on mac: indexMac.html opens. Win files are invisible. I know that every usb stick can be read by both platforms. The Apple Mac os X CD is something which inspired me. thanks a lot.

• Typing the tab character in browser text boxes

  - by Rohit

  A lot of the time, when I want to format text within a web page's text box I'll hit the Tab key. Unfortunately, that doesn't insert the tab character but instead moves the control to the next form element (like a button or a check box). For browsers like Firefox/IE, is there a way to get the formatting behavior of a tab, within a text box, by typing a key combination?

• Multitasking on iOS4 and its stated battery efficiency

  - by eml

  Apple stated that the reason multitasking didn't arrive before iOS4 is because they hadn't figured out how to do it right. Jobs stated at Apple WWDC 2010 that they now do and that they solved the problem of preserving battery performance regarding multitasking. Is iOS4's multitasking "feature" indeed more efficient regarding battery performance compared to Android? Have the Android developers managed to "do it right" too?

• How to automatically save sessions with multiple windows in FireFox

  - by Matthew Talbert

  I've used primarily FF's built-in session management until recently. Now my needs have become more sophisticated. What I want is to be able to have two windows, one with a fixed set of tabs (approximately 5) and the other with "automatic save". That is, when I start FF, I want 1 window to open with my 5 tabs, and another to open with whatever I had when I shut down FF. I've installed "Session Manager", but I can't seem to get it to do what I want. It will save one window, but when I close one window, it removes that one from the session. Any suggestions to do this with either Session Manager or another plugin would be great.

• Mac: window manager frozen, have ssh access

  - by Bernd

  I have a Mac which regularly runs into a problem. The user interface stops reponding, showing a "frozen" user interface. The mouse is still moving but clicking does not trigger anything. This happens about once a week. Solution so far is to force switch-off the Mac and reboot it. I have ssh root access to the Mac. Killing (kill -9) the active application has no visible impact on what is shown on the screen. Any ideas on how to diagnose this? Is there a way to restart the window manager from the ssh shell? Killing /System/Library/Frameworks/ApplicationServices.framework/Frameworks/CoreGraphics.framework/Resources/WindowServer seems not to be possible. The Mac is an early 2008 iMac and runs Lion with latest updates. /Library/Logs/DiagnosticReports is empty. Update: Problem stays after update to Mountain Lion. The WindowServer process is in "uninterruptible wait" state ("U" flag in ps output set): imac:~ root# ps ax|awk "NR==1|| /WindowServer/"|grep -v awk PID TT STAT TIME COMMAND 86 ?? Us 50:51.69 /System/Library/Frameworks/ApplicationServices.framework/Frameworks/CoreGraphics.framework/Resources/WindowServer -daemon Any idea for diagnosing what blocks the process? Any idea for "waking up" the process?
