• Is there a way I can choose what individual files to download within a .torrent?

  - by Valamas

  Is there a way to get the list of files under the files tab without the download starting? Sometimes I am after a single file within a torrent, however, to see the list, I need to start downloading. I then select the only file I want to download, but the other files which started to download and were stopped still will appear on the completed side even if 1k/600k of that file has downloaded. You can imagine the mess and confusion this can cause. So, is there a way I can instruct my BitTorrent/uTorrent program to just grab the file list? Solution: You must download the .torrent file. This contains the list of files. If you download using a magnet link, you do not get the list of files until the torrent starts.

• is there a way to prevent network manager from storing the password for a wireless network

  - by tolomea

  Our corporate wireless network uses continuously changing passwords with RSA tokens. So every time we need to connect to the wireless we need to enter a new password off the RSA token. For extra fun using the wrong password a couple of times in a row causes the users account to be locked. Network manager automatically stores and reuses the password, with the net result that it is constant getting my account locked. Is there some way to prevent it from storing my password for that network? Or perhaps someway to get the gnome keyring to not store it?

• Dom U Installation on Ubuntu 11.10

  - by sridutt

  I am trying to add a DomU Operating system on Ubuntu 11.10. I have successfully installed Xen. Verified with xm info virsh-version which returns: Compiled against library: libvir 0.9.2 Using library: libvir 0.9.2 Using API: Xen 3.0.1 Running hypervisor: Xen 4.1. Now when I tried to install Dom0 it said: unable to connect to 'localhost:8000': , in VMM. So, I followed this bug link. I could now start adding DomU. When adding DomU, in last stage, it gives the following error: Unable to complete install: 'POST operation failed: xend_post: error from xen daemon: (xend.err "Error creating domain: device model '/usr/lib/xen/bin/qemu-dm' not found")' Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 44, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/create.py", line 1899, in do_install guest.start_install(False, meter=meter) File "/usr/lib/pymodules/python2.7/virtinst/Guest.py", line 1223, in start_install noboot) File "/usr/lib/pymodules/python2.7/virtinst/Guest.py", line 1291, in _create_guest dom = self.conn.createLinux(start_xml or final_xml, 0) File "/usr/lib/python2.7/dist-packages/libvirt.py", line 1686, in createLinux if ret is None:raise libvirtError('virDomainCreateLinux() failed', conn=self) libvirtError: POST operation failed: xend_post: error from xen daemon: (xend.err "Error creating domain: device model '/usr/lib/xen/bin/qemu-dm' not found") I tried following this bug link that said, the bug is solved in the below package.

• BSODs after Windows 8.1 Upgrade

  - by Techrocket9

  I just upgraded my system to Windows 8.1, and I have been getting BSODs that I did not get before the 8.1 upgrade. Though I cannot conclude that running the Android Emulator with Intel's HAXM is the cause, both crashes have occurred while the emulator was running. I get CRITICAL_STRUCTURE_CORRUPTION, the same error as this guy, except I don't have the hardware/software that he has that caused his problem. Minidumps here. Output of verifier.exe /all and then a reboot and then verifier /query: http://sdrv.ms/17CPVu9 Edit: According to software.intel.com/en-us/forums/topic/475129 (can't link due to lack of rep) it is being caused by HAXM. Will close question when I find a solution.

• At what point does programming become a useful skill?

  - by Elip

  This is probably a very difficult question to answer, because of its subjectivity, but even a vague guess would help me out: Now that Khan Academy is beginning to offer Computer Science lectures I'm getting an itch to learn programming again. I maybe am a bit more technical than your average computer user, using Ubuntu as my OS, LaTeX for writing and I know some small tricks like regular expressions or boolean search for google. However from my previous attempts to learn programming, I realized I do not have a natural aptitude for it and I also don't seem to enjoy the process. But I am fairly certain that a basic proficiency in programming could prove to be very beneficial for me career wise; I also often get ideas for little scripts that I cannot implement. My question is: Let's say you study programming 1 hour / day on average. At what point will you become good enough so that programming can be used for automating tasks and actually saving time? Do you think programming is worth picking up if you never have the ambition to make it your career or even your hobby, but use it strictly for utility purposes?

Next, it says that the table mysql.host does not exist. I was unable to figure out what this is caused by.

• Adding a web folder via command line (Windows)

  - by Ryan

  I am trying to add a web folder via command line in windows. At first I though I should use the "net use" command, but when I tried I kept getting System error 67: C:net use * http://dev.subdomain.domain.tdl/dav/ the user name for 'dev.subdomain.domain.tdl': correctusername the password for dev.subdomain.domain.tdl: System error 67 has occurred. The network name cannot be found. The url I used works in a browser. It's an Apache dav on basic auth LDAP authentication method being used. Here's the thing... I CAN create a web folder when I use the "Add a network place" wizard. When I do net use, I don't see it listed in the prompt that follows. What utility do I need to use to mount a web folder in command line?

• Maximum burn speed keeps decreasing from Nero?

  - by Bob King

  I have a 16x DL DVD burner in my work machine (XP SP3). I'm using 8x TDK DVD+R media. The first dozen or so disks burned fine using Nero, but after that I started to coaster every disk. I asked Nero to calculate the maximum speed, and it calculated it at 4x. This worked for a few disks, then the same issues. I'm currently burning at 1.2x. I've since tried other brands and full 16x compatible disks, I can't get my burn speed to be recognized as any faster than what it's currently at. I've tried uninstalling Nero. I've tried burning directly in Windows, and also tested an MP3 CD in iTunes, and no luck. Any suggestions, short of reinstalling Windows, would be great!

• How do spambots work?

  - by rlb.usa

  I have a forum that's getting hit a lot by forum spambots, and of course the best way to defeat something is to know thy enemy. I'll worry about defeating those spambots later, but right now I'd like to know more about them. Reading around, I felt surprised about the lack of thorough information on the subject (or perhaps my ineptness to input the correct search terms for better google results). I'm interested in learning all about spambots. I've asked on other forums and gotten brush-off answers like "Spambots are always users registering on your site." How do forum spambots work? How do they find the 'new user registration' page? (I'm especially surprised because some forums don't have a dedicated URL for this eg, www.forum.com/register.html , but instead use query strings or even other methods invisible to the URL bar) How do they know what to enter into each 'new user registration' field? How do they determine what's a page they can spam / enter data into and what is not? Do they even 'view' this page at all? ..If not, then I'd assume they're communicating with the server directly - how is - this possible? How do they do it? Can forum spambots break CAPTCHAs? Can they solve logic questions (how?)? Math questions? Do they reverse-engineer client-side anti-bot validation scripts? Server-side scripts? What techniques are still valid to prevent them? Where do spambots come from? Is someone sitting behind the computer snickering as they watch their bot destroy site after site? Or are they snickering as they simply 'release' it onto the internet somehow? Are spambots 'run' by an infected computer somewhere? Do they replicate themselves? etc

• Can a processor upgrade cause BSOD?

  - by Daniel

  I Had the following hardware setup: Phenom II X4 945 Asus M4A97 4GB DDR2 OCZ Radeon HD5850 OCZ Agility 2 120 GB Windows 7 x64 Pro Fully updated (latest drivers and windows update patches) Then I bought an used Phenom II X6 1090T and installed it without formatting. Since that my computer started BSODing almost every time I'm playing any game and with different error messages, like: page fault in non-paged area bad pool header the video memory manager found a problem error in dxgmm1.sys(or something like that) And when it doesn't BSOD the game simply crashes. I have tried: Updating BIOS Reseting BIOS to defaults Reinstalling Video Drivers Installing the latest DirectX All that's left is to do a full format and I don't want to do that since it's going to be a lot of work to fine tune windows to my preferences again. So is my "new" processor defective or do I really need to format the computer? Update: I use a (properly installed) custom cooler from Coolermaster and both the BIOS and the Open Hardware Monitor(Application) attest the CPU is not overheating, so I guess the CPU its defective and since I bought it from a guy over the Internet I'm probably screwed

• Does Windows 8 Need New, Specialized Drivers?

  - by Synetech

  It seems like an obvious question, but I’m having a difficult time finding out if Windows 8, with all its changes, will require new, specialized drivers. I see that a lot of manufacturers have started releasing Windows 8-specific drivers for their hardware, but what about those that are not, will Windows XP or 7 drivers work or have they changed the driver/system/security architecture again, thus requiring new drivers? The closest thing I could find to an answer was a thread in which it was mentioned that the display driver model was again updated, thus requiring new display drivers, but not much else (e.g., audio cards, printers, chipsets, etc.)

• LiveCD not booting/can't install Ubuntu 11.04

  - by user20318

  So, i got a new laptop somedays ago and as usualy, i went formated it to install Ubuntu. Download 11.04 and burned it on my pendrive using my old laptop (running 11.04). When i tryed to boot from the LiveUSB on my new laptop, it just showed me some weird graphics and if i select any option (can't see what im selecting), it gives me a black screen and that is all. Then i tryed to boot with this LiveUSB on my old laptop, and it worked just fine ._. Burned a CD with Ubuntu 11.04 (64bits) and the problem continue. Then i tought it could be my CD Driver, since the laptop is new and all... burned a Windows 7 64 bits DVD and it worked just fine. Also, if i check the CD/Pendrive inside Windows Seven, all the files there are ok. Anyone have any idea of what can be? I found lots of questions about this, but none of them had the weird menus i'm getting ._. oohh... i also get a "prefix is not set" before the weird menu appears :S My sis specs: Intel Core i5 2400 Intel HD 3000 4gb DDR3 If anyone can help, i will be really greatfull ._.

• Load testing nginx inside AWS

  - by andy

  I'm trying to load test nginx running on AWS. I need to try to optimise it to handle 1Gbps of inbound traffic. Currently I've got it to peak at 85Mbit/s by running nginx on an m1.large with 4 other machines hitting it by using ab with -i (for head requests) -k (keepalives) -r (ignore failed requests) -n 500000 -c 20000. I'm struggling to generate more than 85 Mbit/s traffic from 4 machines, yet when I do scp a large file I get nearly 0.25Gbit/s of traffic going over the network. Are there any tools or approaches that I could use to load test nginx that might generate more load? I'm only interested in inbound traffic, so perhaps a DoS tool could help if it chucks away responses? I'm hitting a very small (40 byte) static asset, and have peaked at handling 50K concurrent connections and getting 25k reqs/s when just using a single load generator machine.

• Korea&rsquo;s Anti Abortion / Pro Life Movement

  - by Randy Walker

  The South Korean government is in dire straits.  The national birth rate continues to decline and as the population grows older, there aren’t enough children being born to support the country long term.  The social issues of post Korean War are coming back to haunt the empowered nation.  Being torn apart by the Korean War (nicknamed the forgotten war in America) and with a nation facing starvation, South Korea allowed hundreds of thousands of their children to be adopted abroad.  This has created a problem of epidemic proportions, essentially devaluing life in Korea and child rearing. In an effort to encourage birth rates, the government encouraged their workers to go home early and procreate by turning off the lights in buildings.  Something unknown to me, was the illegalization of abortion except in special cases. According to the this article, http://joongangdaily.joins.com it’s working.  Abortions are down and women are being encouraged to give birth.  However the flip side is illegal risky abortions are on the rise, with potential back alley abortions looming.  But with a nation facing it’s potential implosion, it has to continue it’s efforts to encourage mothers to give birth. Many of the issues that America has faced is in stark contrast to South Korea.  Abortion has been a generally accepted procedure for some time.  If you’ll recall, I mentioned South Korea devalued their children.  But the nation’s problems lie so much deeper.  Being an Asian nation, saving “face” is an important aspect of life.  And being an unwed mother disgraces the family.  Living as a single mother in South Korea is a difficult life.  Most married mothers stay at home to take care of the children.  Being a shunned single mother that has a hard time getting a job (because you are a single mother) and affording child care isn’t like life in America. If we in the states suddenly faced a birthrate crisis, what would the U.S. government do?

• check_postgres_checkpoint plugin error

When I run the command from CLI as root I am getting the output but I am not able to get the output in the Nagios web interface. The error which it shows is, ERROR: pg_controldata could not read the given data directory: "/opt/PostgreSQL/9.1/data" It is trying to access the pg_control file in the 'global' directory present beneath the data directory which has only read access to the postgres user. Can anyone please suggest me how this can be resolved ? Thanks.

• XNA 2D vehicle wall collisions

  - by mike

  I am attempting to implement collisions for my truck game, where the truck can drive around the world and hit walls surrounding the level and various randomly placed walls within the level. I am able to get direct collisions working correctly. However, it is getting very complicated and tricky very quickly. I am trying to accommodate various other collisions such as when a truck is against the wall then turns an adjacent direction or when they reverse into a wall. Both of these result in a slight collision as the image of the truck flips around to the direction the player wants to move. All of this has resulted in a whole lot of if statements to check how I should be fixing the collision. This in turn makes the player jump to random locations and "teleport" around corners, etc. The rest of my game is fine, I am not completely new to game development or C# for that matter. It's just the logic of collisions. Any ideas on how I can approach this? Image of the collisions I am trying to resolve: http://tinypic.com/r/2qtflvq/6

• mod_rewrite ssl redirect

  - by Thomas

  Hi all, I want to use mod_rewrite to ensure that certain pages are served with SSL and all others normally, but I am having trouble getting it to work This works (redirect to SSL when request uri is for users or cart) RewriteCond %{SERVER_PORT} 80 RewriteCond %{REQUEST_URI} users [OR] RewriteCond %{REQUEST_URI} cart RewriteRule ^(.*)$ https://secure.host.tld/$1 [R,L] So, to accomodate for a user not to keep browsing the site with ssl, when requesting other uris, I thought the below, but doesn't work: (when port is 443 and request uri is not one of uris that need to be served by ssl, redirect back to normal host) RewriteCond %{SERVER_PORT} 443 RewriteCond %{REQUEST_URI} !^/users [OR] RewriteCond %{REQUEST_URI} !group RewriteRule ^/?(users|groups)(.*)$ http://host.tld/$1 [R,L] Any help?

• Quitting a small start-up where you are a primary developer?

  - by programmx10

  Just curious to hear from other people who may have been in similar situations. I work for a small startup (very small) where I am the main developer for a major part of the app they are building, the other dev they have does a different area of work than I do so couldn't take over my part. I've been with the company 5 months, or so, but I am looking at going to a more stable company soon because its just getting to be too much stress, overtime, pressure, etc for too little benefit and I miss working with other developers who can help out on a project. The guy is happy with my work and I think I've helped them get pretty far but I've realized I just don't like being this much "on the edge" as its hard to tell what the direction of the company is going to be since its so new. Also, even though I'm the main dev for the project, I would still only consider myself a mid-level dev and am selling myself as such for the new job search. Just to add more detail, I'm not a partner or anything in the company and this was never discussed, so I just work on a W2 (with no benefits of course). I work at home so that makes it easier to leave, I guess, but I don't want to just screw the guy over but also don't want to be tied in for too long. Obviously I would plan to give 2 weeks notice at least, but should I give more? How should I bring up the subject because I know its going to be a touchy thing to bring up. Any advice is appreciated UPDATE: Thanks everyone for posting on this, I have now just completed the process of accepting an offer with a larger company and quitting the startup. I have given 2 weeks notice and have offered to make myself available after that if needed, basically its a really small company at this point so it would only be 1 dev that I would have to deal with... anyways, it looks like it may work out well as far as me maintaining a good relationship with the founder for future work together, I made it out to be more of a personal / lifestyle issue than about their flaws / shortcomings which definitely seems to help in leaving on a good note

• Determine compression ratio for Windows compressed drive

  - by munrobasher

  Is there a Windows 7 native way to display the overall compression ratio on a Windows compressed drive? As part of our disaster recovery process, we're copying some key system folders onto 2TB external hard drive, encrypted using TrueCrypt and copied using robocopy. The drive is compressed and I'd like to see what kind of compression ratio we're getting and whether it's actually worth the performance overhead. I know that TreeSize can possibly do this (as mentioned in another post) but want a OS native way if possible. Thanks, Rob.

• Facebook - Isn't this a big vulnerability risk for users? (After Password Change)

  - by Trufa

  I would like to know you opinions as programmers / developers. When I changed my Facebook password yesterday, by mistake I entered the old one and got this: Am I missing something here or this is a big potencial risk for users. In my opinion this is a problem BECAUSE it is FaceBook and is used by, well, everyone and the latest statistics show that 76.3% of the users are idiots [source:me], that is more that 3/4!! All kidding aside: Isn't this useful information for an attacker? It reveals private information about the user! It could help the attacker gain access to another site in which the user used the same password Granted, you should't use use the same password twice (but remember: 76.3%!!!) Doesn't this simply increase the surface area for attackers? It increases the chances of getting useful information at least. In a site like Facebook 1st choice for hackers and (bad) people interested in valued personal information shouldn't anything increasing the chance of a vulnerability be removed? Am I missing something? Am I being paranoid? Will 76.3% of the accounts will be hacked after this post? Thanks in advance!! BTW if you want to try it out, a dummy account: user: [email protected] (old) password: hunter2

• Super slow time machine backup on my mac

  I just got a new 2TB drive which I'm trying to use as a time machine drive for my mac which has a 1TB drive. On my first time trying to back it up, I'm getting terrible throughput, not even 1GB per day (it's been running for 36 hours now). I erased the disk and tried to copy a large file to it and got the same slow speed. What can I do to diagnose this? Are there any tools which can inspect the disk and tell me if it's messed up? Thanks!
