• How to protect private files from others to view/copy on a LAN

  - by Mehper C. Palavuzlar

  I'm on a company network and I want to protect my private files (or folders) from others (i.e. those who can access my computer) to view and copy. Those files are mostly MS Office and PDF files. What kind of free protection methods can I use?

• How do I set up ZScreen to upload images to my mediawiki?

  - by Johan

  I've set up a mediawiki with all the correct settings and enabled image uploading. When I do this manually this all works OK. I want to be able to upload screenshots automatically into my mediawiki using ZScreen. There is an option to do this: I press Test..., this work OK, however I'm unable to tell ZScreen to to actually get the picture into my mediawiki. There's no option to select mediawiki as my destination. How do I setup zscreen to upload to my mediawiki?

• Attempting to migrate to Aptana from Dreamweaver - how to?

  - by Kerry

  I have been using Dreamweaver for years, and have used Dreamweaver MX, Dreamweaver MX 2004, Dreamweaver 8 & Dreamweaver CS4. They all carry a common theme and were relatively easy to migrate to each other. I use, however, very few features of dreamweaver. Specifically: Syntax highlighting Telesense FTP management/site management The search/replace The idea I get from Aptana is its much more geared toward the web development/programmer side of things, have better visualizations of classes, etc., and handle everything else just as well. The problem is it is not at all clear to me. I managed to start a new project, but it didn't associate it with an FTP. So, I created an FTP, and it looks like I can have many FTPs for one project. My question then is, is there a tutorial or guide to migrating to Aptana from a Dreamweavor's perspective?

• Acer Aspire One getting extremely hot

  - by ascom

  I have an Acer Aspire One D250-1197. I really better type fast before it overheats again... For some reason, I'm having a problem with heat on my netbook only when I run Joli OS (Ubuntu 9.10 LTS?). When I leave it idle, with nothing running (other than the regular Joli OS desktop and a couple of doing-nothing terminals), heat slowly builds up to the point where the netbook is burning hot to the touch. I have never had this problem when running Windows 7 Starter (even though it gives me plenty of other headaches). It seems that the fan is spinning, but not fast enough to keep up with the heat buildup. Is there something wrong with the fan drivers? The computer doesn't seem to recognize that it is overheating. What can I do to solve this problem (other than shut it off or use Windows)? I'm currently on the wrong side of Earth (I mean, on vacation), so I just need a temporary fix, such as a driver I can install. Also, I have to use Linux, because I have to share out the wired connection in hotels wirelessly to the iPhones. EDIT: I'm switching from Joli OS to a more "proper" and up to date distribution (Xubuntu 13.04). I'll see if it still has the heat problem and try @nod's cpufreq idea.

• Split section of video with ffmpeg

  - by Rob

  I've been trying to get this to work and I'm really close, but something still isn't right. I have a 14 second clip I'm trying to cut out of a longer mp4 video. I got the video to cut to the right place with this command: ffmpeg -ss 00:05:13.0 -i ~/videos/trim_me.mp4 -vcodec h264 -acodec copy -t 00:00:14.0 ~/videos/trimmed.mp4 If I didn't specify -vcodec it was starting from an "I-Frame" (I guess) and wasn't the right place. The audio is starting from that spot as well, so I tried setting -acodec the same way: ffmpeg -ss 00:05:13.0 -i ~/videos/trim_me.mp4 -vcodec h264 -acodec aac -ac 2 -ab 225k -ar 48000 -strict -2 -t 00:00:14.0 ~/videos/trimmed.mp4 Which doesn't really help much. Setting -async 1 makes it take longer, and then the audio does match up, but not until 4 seconds into the video. :/ I'd ideally not like to install anything else and have a commandline solution for this.

• BSOD trying to migrate Windows XP from a physical to a virtual machine

  - by pauldoo

  I am attempting to migrate a Windows XP Home installation from a physical machine to a virtual machine. The physical machine has two hard disks; the first is 250GB containing the "C:", the second is 1TB containing "D:". I'd like to create a new virtual machine stored on the D:, which is a copy of the Windows XP Home installation that is currently on the C:. (This will leave the 250GB drive clear for me to install a fresh copy of Windows 7, and still be able to access the old XP installation if necessary.) The first method I tried was to follow the instructions here: http://www.virtualbox.org/wiki/Migrate_Windows I booted up from an Ubuntu Live CD in order to execute the Linux commands whilst the Windows system wasn't running. With this method the virtual machine would always blue screen on startup with a "STOP 0x0000007B" message. The instructions above say to try a "repair install" using the Windows XP disc. Unfortunately for me my XP disc is scratched and will not boot so I was unable to try a repair install. The second method I tried was to use "VMWare Converter Standalone Client". This tool executed without any errors, but again produced a virtual machine that blue screens on startup with the same "STOP" message. Are there any other methods to move the Windows XP installation into a virtual machine? I think next I will try some more manual process to create the cloned virtual machine. I think I will try installing a fresh copy of Windows XP to a virtual machine, then once that is booting OK I will ntfsclone the source C: partition over the top. Perhaps this will fix the booting problems if the issue is related to the MBR or partition table in some way.

• compose-key mappings differ between gtk and qt apps

  - by intuited

  I'm noticing that there is an inconsistency in the output of one of the compose-key combos. When I type ( [Compose] . . ) under Chrome, gedit, gnome-terminal, or roxterm I get the character '?'. This is a small raised dot: $ echo -n '?' | xxd 0000000: cb99 .. When I type the same combo under konsole, yakuake, or kate, I get the character '…'. This is an ellipsis: $ echo -n '…' | xxd 0000000: e280 a6 ... This is not a font issue: if I copy-paste the characters from an app using one toolkit to an app using the other, its appearance is maintained. I use a few other combos pretty regularly and they seem to work consistently across toolkits. I think this is a pretty recent phenomenon. I upgraded from Ubuntu 8.10 to 9.10 fairly recently so this might be related. I'm not sure if this will reoccur if I restart X, and I'd rather not find out. Can someone explain how this is possible, and what I can do to resolve it? I'd like to have the ellipsis appear in all apps when that combo is entered.

• How can I re-encode H.264 video with minimal quality loss?

  - by SofaKng

  I have a lot of MPEG-TS files (.TS container but H.264 video) and playback is fine except that when you skip forward/backward or fast forward it's very sluggish and gets pixelated, etc. I've been trying to do research and I'm guessing that they were encoding with very few reference blocks (ie. it's a capture from a DVB-S satellite stream). When I re-encode them with Handbrake (.MP4 container) they play very, very good and seeking in the video is instant, etc, etc. Is it possible to transcode/re-encode my MPEG-TS files with minimal quality loss? If so, what is my best bet? They are each about 2 Mbps (ie. 2 GB per hour) but I don't want to re-encode them if "minimal quality loss" requires 10+ GB per file. I'm hoping to keep the video are the same size. Can anybody give me any advice?

• AMD FX8350 CPU - CoolerMaster Silencio 650 Case - New Water Cooling System

  - by fat_mike

  Lately after a use of 6 months of my AMD FX8350 CPU I'm experiencing high temperatures and loud noise coming from the CPU fan(I set that in order to keep it cooler). I decided to replace the stock fan with a water cooling system in order to keep my CPU quite and cool and add one or two more case fans too. Here is my case's airflow diagram: http://www.coolermaster.com/microsite/silencio_650/Airflow.html My configuration now is: 2x120mm intake front(stock with case) 1x120mm exhaust rear(stock with case) 1 CPU stock I'm planning to buy Corsair Hydro Series H100i(www.corsair.com/en-us/hydro-series-h100i-extreme-performance-liquid-cpu-cooler) and place the radiator in the front of my case(intake) and add an 120mm bottom intake and/or an 140mm top exhaust fan. My CPU lies near the top of the MO. Is it a good practice to have a water-cooling system that takes air in? As you can see here the front of the case is made of aluminum. Can the fresh air go in? Does it even fit? If not, is it wiser to get Corsair Hydro Series H80i (www.corsair.com/en-us/hydro-series-h80i-high-performance-liquid-cpu-cooler) and place the radiator on top of my case(exhaust) and keep the front 2x120mm stock and add one more as intake on bottom. If you have any other idea let me know. Thank you. EDIT: The CPU fan running ~3000rpm and temp is around 40~43C on idle and save energy. When temp is going over 55C when running multiple programs and servers on localhost(tomcat, wamp) rpm is around 5500 and loud! I'm running Win8.1 CPU not overclocked PS: Due to my reputation i couldn't post the links that was necessary. I will edit ASAP.

• MySQL is killing the server IO.

  - by OneOfOne

  I manage a fairly large/busy vBulletin forums (~2-3k requests per second, running on gigenet cloud), the database is ~ 10 GB (~9 milion posts, ~60 queries per second), lately MySQL have been grinding the disk like there's no tomorrow according to iotop and slowing the site.

• USB to LPT adapter?

  - by Dave

  I'm bummed out, pretty much all of our computers here lack parallel ports. I have an EETools ChipMax programming tool that has one of the old-school Centronics connectors on the back. I figured that someone must make a USB to LPT adapter. Sure enough, I found one from iogear, the GUC1284B that is a USB to Parallel Printer cable. Note the boldface on the Printer. It must connect to a printer -- it isn't some generic USB to parallel interface, unfortunately. Does anyone here know of an adapter that works for parallel devices that aren't printers? I'd hate to have to buy a USB version of the ChipMax when I don't need to use it very much.

• Sharing laptop's internal optical drive running windows XP Media Center Edition with Netbook running

  - by Col

  just got a new HP netbook with no optical drive and guide said I should be able to share the optical drive of another windows computer. The netbook is running Windows 7 and the laptop, also HP, with the internal optical drive is running Windows XP Media Center Edition. I have wireless network that both the laptop and netbook access without a problem. The instructions did not seem to work in my case. When I right clicked on Properties of the optical drive and went to the Sharing tab, there was no selction for Advanced Sharing as the instructions said. XP made me go to Network wizard and set up a network, (which I already had). After doing that I could not access the drive from Windows 7. Has anyone benn able to do this?

• Small program for rotating images

• How to access VMWare localhost from my mac?

  - by Abe Miessler

  I have developed a asp.net application on my VMWare virtual machine that I can access (on my VM) by going to http://localhost:1044 How can I access this from safari on my Mac that is running the VM? I tried running ipconfig on my VM and then using the IP address that was given for "Ethernet adapter Local Area Connection", something like this: http://192.168.179.139:1044/ but this throws a not found error. I am currently using NAT. How can I get to localhost on my VM from my mac?

• How do I keep folders synced and backed up between two macs using a Linux NAS (rsync?)

  - by Hultner

  I've got two primary computers, one Mac Pro and one MacBook Pro for when I'm on the go. I've also got a Linux sever which also acts as NAS. Currently I backup the entire computers to an external drive with Time Machine which is rather useless and doesn't sync anything. What I really want to do is to keep my important files synced between both computers and my NAS (which is running RAID 5), that way I'm not backing up easily replaceable systemfiles and I've got all my important files in 3 places where two of them are running raid so at least 5 drives would have to crash at the same time before actual data loss occur. Folders I want to keep synced is basically my photo, documents, development, mamp and work folders and then I want to keep the user library folder backed up but not synced. I'm thinking that I'd have to use rsync but don't know how. Before suggesting Dropbox and similar suggestions I don't want to use them because of several reasons some of them being security (Dropbox obviously proved this), Speed (sometimes I'll sync gigabytes of data and that will be significantly faster locally and probably even through VPN as I have a Gigabit pipe), Space (space on my NAS is cheap and only practically limited by my needs), reliability (even if my internet were to go down I still need to be able to keep my files synced incase I'd need to go somewhere on the fly), price (I already have all the hardware and for the amount of gigabytes and bandwidth I'd need I doubt that there's any free or cheap service). Those are my main reason for wanting to keep it locally. I'm sorry for any spelling or grammatical mistakes that I've might have done. I'm writing this on my smartphone from a shaky train and English isn't my mother tongue. I gratefully appreciate any answers even if only partly solving my problem.

• How do I see what connections are being made?

  - by Coldblackice

  My DDWRT router is showing that my computer has a connection count around 600! The router is at 100% CPU use. How can I see what's making all the connections? So far, I've opened up Resource Monitor and checked the network tab. I can sort by which program is using the most network bandwidth (Pale Moon browser), but I can't see what's making all of the connections. Or rather, where all the connections are being toward (trying to find what tab must be making all of these connections). I've also tried netstat -A, but it apparently doesn't show the actual number of connections being made. At least, the list of established connections isn't very long, by any means (like enough to account for the 500+ connections apparently being made.

• Sensei mouse sensitivity

  - by Marcelo

  I've recently acquired a Steelseries Sensei. Despite being a great mouse, I'm having some trouble finding settings that I can get used to... The mouse engine allows me to set a CPI from 0 to 5700. It also allows me to set it even higher, calling it "DCPI" (Double CPI), from 5701 to 11400. On Window's Control Panel, there's a "Pointer Speed" slider and a "Enhance Pointer Precision" checkbox (wording may be different as I use a non-english version). The majority of games allow me to set an in-game "Mouse Sensitivity". Some games let me use a "Raw mouse input". I'm already familiar with the basics of CPI/DPI - "higher CPI means less hand movement", but what are the differences between all those options? Is there a "better" or "worst" setting?

• Home ZFS based NAS...What processor/chipset to use?

  - by MrBlargityBlarg

  So, I'm building a home/personal NAS. My plan is to expose both SMB fileshares for sharing files/media between hosts, but also to carve an iSCSI target LUN out of it for use by VMWare as a datastore. I want to use ZFS (software RAID) so that means I'll either be using FreeNAS, Solaris Express, or OpenIndiana. My question is basically: How much horsepower do I need? Obviously I/O is going to be my bottleneck but I want to be sure that I am not limiting my I/O because of a slow processor or chipset. So far the hardware plan is to use an Intel i3 and motherboard with one of the H87, Q87, or Z87 chipsets, a SAS controller (JBOD, no RAID) and if budget allows, I'm also hoping to get an SSD for the ZFS L2ARC and ZIL. Does anyone think I could get away with an Intel Atom or cheaper/less-capable processor/chipset than the i3 and [HQZ]87 listed above?

• What is the difference in RAM speeds?

  - by jasondavis

  I am building a new PC with the intel i7-930 processor. I am wanting to use 12gb of RAM for it (6x2gb sticks). Here is some of the RAM I am looking at G.SKILL 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Triple Channel Kit Desktop 2 of these 3 stick kits. They are rated at 1600 however some of the user reviews on that product say they xcould not get it to run at 1600 and the supplier who makes the RAM made a comment that "I7 doesn't support over DDR3 1066" So I am curious, I do not know much about this, I know the more GB of RAM the better but as for the speeds, I am not sure how much of a difference it makes. So can someone explain to me what the difference in performance may be based on speeds of 1200 vs 1600 ram?

• Seeking glass lcd montiors with LED backlight

  - by dlamblin

  The only LCD monitors with glass fronts and LED back-lighting I can find are the ones by Apple. And they only sell a 24" one at 2.4x the price of any other 24" monitor at 1920x1200, and a 30" one, which honestly I can't put on my desk. Oh, and the 24" one uses a mini-display port plug only. So I'd be out of luck until there's display side adapter available. I am generally looking for a 16:10 or 4:3 rather than 16:9 monitor. It would be awesome if someone could find another, cheaper, monitor that isn't fronted by a plastic film, but rather with glass. It would be double awesome if said monitor was also 120hz so that I can use nVidia's 3D goggles. Update: One month and 16 days later I seem to not be the only one that can't find another glass based computer lcd monitor. LED backlighting is available though.

• Using WinAmp to put music on an iPod/iPhone

  - by levik

  Back in the day, with older iPods, you could copy music onto them using Winamp's Music Library. I heard that newer iPods and iPhones have all sort of encryption that prevents this from being fully functional. I'm looking to buy a new iPod soon, and would really like to avoid installing (or at least keeping) a copy of iTunes on my PC. Are solutions still available through WinAmp? Other software? What iPod/iPhone models would work better?
