  • i5 vs. i7 processor dev laptop

    - by vector
    Greetings! I need to get a laptop for dev work ( mostly server side Java, NetBeans ) and wonder if anyone had a chance to use either the i5 or i7 based laptop? Is the i7 an overkill? ... or will the i5 handle it just fine? I'm thinking something from the HP line running Ubuntu. Thanks

  • Does using cat5e cables yield any disadvantages in combination with cat6/cat6a network?

    - by agent154
    If I were to have a fully compliant cat6 or cat6a network running through my walls... that is to say, wires and jacks... What would be the concequence of plugging a cat5e wire into one of the jacks? I'm assuming that it would still run at cat5e standards, but obviously not cat6/6a standards because the whole connection is not cat6. I only ask because it seems silly to me to make a bunch of cat6 patch cables for connections that don't really matter, like standard desktop computers and other equipment. Or will doing so hamper the whole network?

  • Setting up a fileserver, some questions?

    - by Tanax
    Recently I've become very interested in setting up a fileserver, mostly for home usage but also because of the fact that I live in 2 places, I need to be able to access my files from both homes. I have already done some research into this but I am unclear about some things. My requirements are the following; Needs to work on both Mac and PC(only using Windows atm on PC but could be good if it supports more OS's to make it futureproof in case I need Linux or something else) Need to be able to set up a folder/drive/network space to act as a link to a certain folder on the fileserver All files should only be stored on the fileserver, e.g. no "shared" folders like in Dropbox where files are stored on the client computer Would prefer it if folders are password protected or that I can somehow specify what users can access the fileserver's shares Fileserver's OS most likely have to be Windows due to other factors outside of being just a fileserver I've already kinda figured out that I will need to set up a VPN so that I can access my fileserver from outside the local network. Probably going to use OpenVPN. Question 1: How would I go about to set up a VPN server so that I can connect to my local network at the fileserver's location? I know that since I'm on a dynamic IP I will have to get some sort of dynamic DNS server - I've already checked into this and I'm fairly sure I know how to fix that. I also know that I will have to forward the port OpenVPN uses in my router. Question 2: How would I actually share the folders on the fileserver so that I can access them on my other computers? I've researched into Samba but I'm uncertain if it needs to be run on a Linux OS. I know that the clients connecting to it can be Windows for example but can the Samba "server" be run on Windows? Also it appears that Samba shares a folder, meaning it works like Dropbox - I don't want that. So how would I share a folder in that case to make it work like I want it to? Sorry for the incredibly long question, I tried to structure it the best I could for easier read. Thanks in advance!

  • Htpc aka "Media Center": cheap and *silent*?

    - by Unknown
    It may be me, or the place I live (Italy), but it seems pretty hard to get a build or a prebuilt nettop or a laptop that fits the need. I need something silent able to playback all h.264 fullhd content without stuttering, and well (and not loosing the hw acceleration because of softsubs...) silent not ugly silent and (possibly) cheap. I'm going the linux route, therefore i'm moving towards a cpu-based or nvida-integrated solution (i don't think ati hw accelerated playback - or the intel "hd" acceleration - is useable yet). Ion nettop; it's either the Acer Revo (but here it's incredibly pricey and it's hard to find the dualcore version) or the Asrock Ion 330, that in the current version is rated "silent" at 26Db. 26. Sounds pretty noisy to me!!! the previous version was even worse. was this product really aimed at htpc market?? the Dell Zino - i think it's ATI based unfortunately. Laptop: correct me if I'm wrong: sub 600€/$ units are quite loud under full load (because of the tiny fans). ULW laptops are indeed quite similar: tiniest fans = high pitched noise and the cpu still lacks power for non hd-accelerated video decoding Handmade build: little money can be saved with underpowered cpus, a low-midrange cpu would help in the case of non-hw-accelerated content the cases are quite pricey the PSU one has to get ranges between 100/150 €/$ minimum to keep the noise down a low-mid build, all included, sums up to over 650 €/$ for a still-looking-ugly-unit, without the blu-ray drive. Please help. What do you advise on this? ;) Am I ignoring laptops too much, maybe? Are low-priced Acers that noisy/high pitched under full load?

  • RTL8192SU Linux Issue Installing Driver

    - by s32ialx
    OK I've read tons of fourms of people getting the onboard RTL8192SE working and the RTL8192SU working dif is U = USB they are both N and i have both Toshiba L500D-00T pre-installed Win Vistax64-HP and i have obtained the free Win7x64-HP upgrade the onboard wificard sucks and can't hold a stable connection for more then 20minutes in windows but the usb is amazing. Now problem is i tried both Ubuntu and Mandriva with no resolve the issue is the onboard drive detects and actually SHOWS that it's there but no wireless networks detect so it's saying no SSID's are broadcasting which i know is a lie since I'm running a 2wire bell dsl modem with built in wifi and a Linksys wrt54g w/ DD-WRT firmware and both are broadcasting fine. Why don't i use the USB? In the hardware device manager in mandriva it shows up as unknown but shows that it's realtek and that it's a 8192 chipset. but no option to for a driver install and when i do a make in terminal i get this error and no clue what it means [root@John-PC rtl8192se_linux_2.6.0010.1020.2009_64bit]# make make: *** /lib/modules/2.6.31.12-desktop-3mnb/build: No such file or directory.

  • Copy and Paste without needing to use the Mouse

    - by Paul Farry
    In previous versions of windows when your were Copying Files (Ctrl-C) then alt-Tab (to the appropriate window) and Pasting (Ctrl-V) using the Keyboard everything could be driven by the keyboard. With Vista and 7, it seems if you are copying and pasting (and the files exist) in the Destination Location you have to Click the Copy and Replace, there doesn't seem to be a way to do it... "Do this for the next {n} Conflicts" can be driven by Alt-D, but the "Copy and Replace" and "Don't Copy" are not. Or is there and have I just missed something? I'm more than happy to change registry or something to enable Keyboard shortcuts for this.

  • Multi-core DVD ripping/encoding on the Mac

    - by Paul D. Waite
    A friend of mine likes ripping DVDs to his Mac. He’s currently on an ancient machine, and is about to upgrade to either a MacBook Pro or an iMac. Just wondering if any of the Mac DVD ripping software will rip faster on the iMac (thanks to its four cores), as opposed to the MacBook Pro (a measly two cores)? Or is DVD ripping not that sort of task?

  • Convert DVD to a flash application (including menus)

    - by balint
    I was wondering if it is possible to convert a dvd to a flash application which I could then embed in a website. What I am looking for is not simply ripping the video, but something that encodes the menus and the navigation of the dvd, as well, and the result is an interactive flash application. Thanks! Edit: actually I have the original iDVD project, as well. I would like to turn it into a flash application...

  • 10/100 Network performing at 1.5 to 2.0 megabyte per second - is that below normal?

    - by burnt1ce
    This comes out to about 12 to 16 megabit/seond. I've read in forums that people are getting much higher speeds (ie: "40-60 Mb/s" http://forums.cnet.com/5208-7589_102-0.html?threadID=265967). I'm getting my benchmark by having a unmanged 5 port switch connected to a WRT54GS router connect. I'm sending a file from a computer connect to the WRT54GS to another computer that's connect to the unmanaged 5 port switch. Is the linkage of the switch causing this massive overhead? i doubt it. What could explain the slow down? electrical interference?

  • Second Monitor Gets Bright, and then Blank.

    - by Jonathan Sampson
    I recently added a second LCD monitor to my home-computer. It was working fine for the first couple of days, but then it started having problems. Every 10-20 minutes it would get really bright, and then instantly go black. The power was still connected, so it wasn't turned off. If I turned the power off for a few minutes, I could turn it back on and get another 10-20 minutes of work done before it would happen again. What could cause this behavior?

  • How can I determine what codec is being used?

    - by jldugger
    This forum comment and this superuser answer suggest that the audio compression contributes to loss of quality. I've noticed that music played over my BT setup sometimes pitch bends in ways I don't remember the original doing, and I'm wondering if SBC has something to do with it. I'm using Ubuntu 10.10 on a Mac Pro, connecting to a pair of Sony DR-BT50's. Is there a way to inspect which Bluetooth codec pulseaudio is using, what codecs both ends of the bluetooth link support?

  • How can I remove UNC password from a file

When I tried to change the path of the virtual directory I got the message 'The following child nodes also define the value of the "UNCPassword" property, which overrides the value you have just set ...' which included the mp4 file that we try to access. How can I remove the UNC Password securing the file? The file is not on a shared drive its on the same drive as the web site root. The funny thing is the path of the virtual directory is not a UNC path it's a full path on the same server d:.....

  • Why is my cat5e cable not okay?

    - by torbengb
    My LAN cable seems to work (indicator LED lights up) but the computer can't find a connection. What's wrong? Setup: I had to run a network cable from a router in one room to a computer to another room, through a hole in the wall that was too small to pass the RJ-45 plug through. The plug was cut off and the cable passed through the wall. Then a new plug was crimped on using this detailed explanation. The connection didn't work because the (factory-made!) plug in the other end used a non-standard wire order. I crimped a new plug on again, using the exact same order of the factory-made plug. The LED indicator lights up on both ends, but the computer cannot find a connection. What can be wrong? How can I find out? I don't have a cable tester. By visually inspecting my new plug, I think it's good; the wire order matches the other end, and all wires are all the way inside the plug and reach the connector piece. I've used the cable before (with both factory-made ends) so i don't think that the cable itself has a defect.

  • Using ethernet cables?

    - by Farhad Yusufali
    I have an HDTV which supports internet connectivity through an ethernet port or wirelessly (but this requires an additional wireless USB adapter, which I don't have). I also have a blue ray player than supports internet connectivity through an ethernet port or wirelessly (natively - no other devices are needed). I want to connect my TV to the internet but my router is too far away. My blueray player however is already connected wirelessly. If I connected my TV to my Blueray player via ethernet, would my TV be able to connect to the internet? To clarify: Wireless Signal - Blue Ray Player - Ethernet Cable - TV Would this work?

  • Resolving "JBoss Web Console is Accessible to Unauthenticated Remote Users" vulnerability

    - by IAmJeff
    Our security team has determined there is a vulnerability in one of our systems. We are using version JBoss 5.1.0GA on RHEL 5.10. Vulnerability description: JBoss Web Console is Accessible to Unauthenticated Remote Users Yes, this looks familiar. Refer to Question 501417. I do not find the answer there complete. Can someone (or multiple someones) answer Does a newer version of JBoss fix this vulnerability? Are there links describing, in more detail, manual modification of JBoss configuration files to resolve the issue? Are there others options to remediate this vulnerability? Why don't I find the other answer complete? I'm not at all familiar with JBoss, so this answer seems a bit too simple. The web-console.war contains commented-out templates for basic security in its WEB-INF/web.xml as well as commented-out setup for a security domain in WEB-INF/jboss-web.xml. Just uncomment those basic security blocks and restart? Is there anything else I need to include? This seems generic. Do I need to include anything about my environment, such as absolute paths, etc.? Am I making this too complicated?

  • SMTP Server Times Out for 1 of 2 ISPs

    - by Jonathan Sampson
    For months I've been using a 5g sprint card for my laptop to check email. I have gmail, and three other accounts all configured in Thunderbird. Recently, I got AT&T internet service at my house and I discovered that I cannot send email when connected to my home service. I can receive just fine, but I can't send. If I plugin my 5g card, I can sent/receive with no problems. At home I'm connected wirelessly through a router. What could be causing this interruption? I even tried pinging my smtp server only to see it timeout when connected via AT&T. If more details are needed, I'll be happy to share.

  • run as dialog always pops up

    - by user12006
    I recently got some malware on a machine that I don't use for much (partly intentional). I've cleaned it, but now everytime I open any .exe the 'Run As' dialog pops up asking me which user I want to use to run the program. What causes this, and what's the fix for it? edit My process to remove the malware was as such: Disconnected from the network Deleted DisableTaskMgr reg key Inspected with Process Explorer and Task Manager and noticed that all applications were being run within another executable located in Documents and Settings...\Temp\Some.exe The system tray application was also in Documents and Settings...\Temp\SomeOther.exe I suspected that a service was in place as the system tray application would restart if it was killed, but couldn't find any service that I didn't recognize. Removed permissions from Some.exe and SomeOther.exe (on those files only) Restarted and deleted Some.exe and SomeOther.exe Deleted startup entries that were created Ran AVG Free and Windows Defender to remove anything else (they would be killed immediately before the two .exe's were removed) Cleaned registry via CCleaner note that system restores would finish saying something to the effect of 'couldn't restore system: there were no changes made'. I attempted to restore to a week ago, and I only got the malware yesterday.

  • How to configure a Router (TL-WR1043ND) to work in WDS mode?

    - by LanceBaynes
    I have a WRT160NL router (192.168.1.0/24 - OpenWrt 10.04) as AP. It's: - WAN port: connected to the ISP - WLAN: working as an AP, using 64 bit WEP/SSID: "MYWORKINGSSID", channel 5, using password: "MYPASSWORDHERE" - It's IP Address is: 192.168.1.1 Ok! It's working great! But: I have a TL-WR1043ND router that I want to configure as a "WDS". (My purpose is to extend the wireless range of the original WRT160NL.) Here is how I configure the TL-WR1043ND: 1) I enable WDS bridging. 2) In the "Survey" I select my already working network. 3) I set up the encryption (exact same like the already working one) 4) I choose channel 5 5) I type the SSID 6) I disable the DHCP server on it. After I reboot the router and connect to this router (TL-WR1043ND) over wireless I'm trying to ping google.com. From the ping I see that I can reach this router, that's ok, but it seems like that this router can't connect to the original one, the WRT160NL (so I don't get ping reply from Google). The encryption settings/password is good I checked it many-many-many times. what could be the problem? I'm thinking it could be a routing problem, but what should I add to the "Static Routing" menu? I tried to change the IP address of the TL-WR1043ND to: 192.168.1.2 So if this a routing issue then I should add a static routing rule that says: If destination: any then forward the packet to 192.168.1.1 p.s.: I updated the Firmware to the latest version. It's still the same. p.s.2: The HW version of the TL-WR1043ND is 1.8 p.s.3: Could that be the problem that I use different routers? (If I would buy.. another TL-WR1043ND and use it instead of the WRT160NL, and with normal Firmware, not OpenWrt, then it would work?? The "WDS" is different on different routers?) p.s.4: I will try to check the router logs@night - and paste it here! :\

  • v4l - capture and watch at the same time

    - by John Barrett
    Capturing v4l and line-in audio using mencoder works very well, but I would like to record real-time gameplay video from consoles plugged into the video card. I've used xawtv for this (Works quite well, can preview and record in real time), but when I enable any deinterlacing or aspect ration options the video fails to record. I have to record raw and re-encode the video with the appropriate filters later to get something workable. Other things I have tried: tvtime with xvidcap and jack audio capture - xvidcap drops frames and muxing the audio is impossible as it will go out of sync (I have not found muxer options that work to force a correct frame rate) mencoder capture to file, attempt to pipe tail of file to mplayer... mencoder works great, piping the file is far too heavy to attempt gameplay. Soooo, v4l capture and preview simultaneously, recommendations?

  • E-mail hosting provider that can set up aliases with wildcards

    - by Richard Downer
    I am looking for an e-mail hosting provider that allow e-mail aliases containing wildcards. In more detail: I own my own domain. I want an e-mail hosting provider to manager e-mail for my domain. Now, to help deal with spam, I often give different e-mail addresses to different organisations. These e-mail addresses always start with the same prefix, but then differ. So, for example, I might give out these e-mail addresses: [email protected] [email protected] [email protected] I want to be able to go to the e-mail provider's control panel and set up an e-mail alias like this: [email protected] -- bounce/discard (because this address has been sold to spammers) joe-*@sample.com -- redirect to [email protected] What's I don't want to do is either have to set up every single e-mail address individually (because I make them up whenever I need them), nor do I want to have a general catch-all for any unrecognised address in my domain (because I don't want to be carpet-bombed with spam when a spammer runs a dictionary attack against my domain name.) Although this seems like a useful feature to have, it seems to be a little-known feature and I've not seen anybody advertise this feature. My current hosting provider offer this but I want to move away from them, so I need another provider that will continue to work with all the e-mail addresses I've been using for years. Alternatively, I could use mail server software that runs on Windows - I have seen some commercial packages offering this feature but they cost more than I can afford - are there any suggestions for low-cost software packages?

  • D-LINK 2450U DSL router: Port forwarding forwading to the modem itself, not the specified IP

    - by axk
    I found a similar question but it has no satisfactory answers. I have a D-LINK 2540U DSL router. It has a basic port forwarding(under DNS - Virtual Servers) configuration in the administration panel where you specify: external port range, protocol, internal port range, server IP address and it is supposed to forward that port to that IP address. When I first set it up for a Real VNC connection it worked fine, just as I expected. Then I added a DynDNS configuration entry in the router's 'Dynamic DNS' section and added an additional SSH (22) forwarding rule. The SSH forwarding also worked fine (now with the dynamic hostname, but I suppose it doesn't make any difference as far as SSH is concerned). Then I removed the SSH rule and after that the VNC forwarding stopped working with the VNC client failing to connect (I have tried to connect with telnet and it also failed to connect, so it wasn't a VNC problem). After adding a rule for port 80 it turned out it would forward on port 80 though not to the specified server IP but to the modem itself. At least it is what it looks like, because it gives me the administration panel when I connect to my external IP (both using a browser and plain telnet in which case I can see that it is mini_hhtpd sitting on the port, which is obviously the modem's administration panel). Have anybody encountered a similar problem with port forwarding? I have tried to do a reset through the administration panel and to restore a backup of the settings made before I started playing with port forwarding, but it didn't help. Should I do a 'hard' reset with the button on the modem? Is it any different from the administration panel's reset (Restore default)?
