• How can I use a Windows 2003 server as a HTTP proxy?

  - by Will

  I'd like to set up an HTTP proxy on a windows 2003 server so that I can access blocked websites such as YouTube from behind a corporate firewall (DAMN THE MAN!). I've never done this before, so I'm not even sure if the picture I have in my head is valid or possible. So I'm stuck behind a firewall that blocks sites that I need to access occasionally but that are blocked because of abuse by slackers. I've got a Windows 2003 server hosted out on the internet (i.e., outside of this odious firewall). I know I can configure my browser to use a proxy for my HTTP traffic, so why not use my server? What I'd like to know is: Is my concept valid? Can this be done, and will it work? How do I configure my server to act as a proxy? What applications may I have to install? Free is fine but don't leave out commercial software TIA

• How does the process of disk partitioning actually work on most HDD's?

  - by Dark Templar

  From what I know of most laptops, you are able to "partition" your disk into as many other drives as you please. The more you cut it up, the smaller your partitions are, but from an organizational point of view, this may be desirable... I was wondering how the filesystem itself becomes partitioned underneath the partitions visible to the user. For instance, a laptop disk is usually divided into platters, each with two surfaces. The surfaces are further divided into "tracks". I guess what I am asking is, is it possible to identify how the disk itself keeps track of partitions? (whether each partition has its own platter? each partition has its own set of adjacent tracks? or some other configuration, or whether the data from different partitions are just randomly interleaved and scattered throughout the disk?)

• frequent abnormal shutdowns/system crashes

  - by user110353

  It's been almost 5 days since I have installed Ubuntu and almost 6th time that my laptop has been crashed entirely and it shuts down abnormally. Actually, it heats up and I have to wait for 20 odd minutes before I can turn it on again. A message appears that my PC crashed due to overheating which may damage my hard disk. The crashes happened when I tried to open some application that freeze my PC not even giving me enough time to go to system monitor and end process. Sometimes the culprit application which caused crash is Ever-pad, sometime it's team-viewer, sometimes it's some other. This is something very serious. The last crash occurred at 09:14:40. Kindly click here to view system log. I want to stick to Ubuntu and the same laptop as I had serious issues with Windows and I nearly went out to dump my laptop and purchase a more powerful system. Below are my hw/os specs. Kindly advice on how to resolve this issue Ubuntu 12.10 Kernal 3.5.0-18-generic GNOME 3.6.0 Memory 2.0GB Processor: Genuine Intel CPU [email protected] x 2 Available Disk Space: 63.7 GB Thanks in advance

• Where can I get a splitter to connect a device with a single 3.5 mm plug into the audio input/output jacks on my laptop?

  - by XinJeisan

  I recently bought the :Hype Retro Handset for Mobile Phone" -- its just a device that looks like a handset to use when chatting on a computer or mobile phone that plugs into the phone/computer with a single 3.5 mm plug. I was hoping to use it on my windows 7 Toshiba laptop. I can hear audio fine through the handset but what I'm saying is not being picked up on the handset. On the box it says "some phones and computers may need additional adapters," so I'm hoping it is possible to get a splitter or something for this to work properly. I did email the parent company (http://dglusa.com/) but I haven't heard from them, and, looking over their website, I doubt I will. I also went to the local radio shack, and the guy said I needed a splitter, but he didn't know where to get one. I can find the kind of splitter I think I need online, but I'm unsure whether they are just for output or can also do input/output.

• How to run a process and completely detach it of its parent shell

  - by Bicou

  I'm running a program on a linux server that will take days to complete. I'm launching it from my workstation from an SSH terminal, as this program is command-line only. I want to be able to do all of these : launch that program, redirect standard outputs to files, exit my SSH session without making this terminate the process. I thought about $ ./MyProg.csh -params -foo -bar </dev/null 1>~/out.log 2>~/err.log & However, the process is terminated the moment I close my SSH session. My workstation is running Windows XP, and I cannot guarantee its uptime over several days, which is required for the processing of my data on the Linux server. As you may have noted, my program requires to be launched from CSH. Is it possible to do this ? Thanks.

• Language Design: Are languages like Python and CoffeeScript really more comprehensible?

  - by kittensatplay

  The "Verbally Readable !== Quicker Comprehension" argument on http://ryanflorence.com/2011/case-against-coffeescript/ is really potent and interesting. I and I'm sure others would be very interested in evidence arguing against this. There's clear evidence for this and I believe it. People naturally think in images, not words, so we should be designing languages that aren't similar to human language like English, French, whatever. Being "readable" is quicker comprehension. Most articles on Wikipedia are not readable as they are long, boring, dry, sluggish and very very wordy. Because Wikipedia documents a ton of info, it is not especially helpful when compared to sites with more practical, useful and relevant info. Languages like Python and CoffeScript are "verbally readable" in that they are closer to English syntax. Having programmed firstly and mainly in Python, I'm not so sure this is really a good thing. The second interesting argument is that CoffeeScript is an intermediator, a step between two ends, which may increase the chance of bugs. While CoffeeScript has other practical benefits, this question specifically requests evidence showing support for the counter-case of language "readability"

• Two components offering the same functionality, required by different dependencies

  - by kander

  I'm building an application in PHP, using Zend Framework 1 and Doctrine2 as the ORM layer. All is going well. Now, I happened to notice that both ZF1 and Doctrine2 come with, and rely on, their own caching implementation. I've evaluated both, and while each has its own pro's and cons, neither of them stand out as superior to the other for my simple needs. Both libraries also seem to be written against their respective interfaces, not their implementations. Reasons why I feel this is an issue is that during the bootstrapping of my application, I have to configure two caching drivers - each with its own syntax. A mismatch is easily created this way, and it feels inefficient to set up two connections to the caching backend because of this. I'm trying to determine what the best way forward is, and would welcome any insights you may be able to offer. What I've thought up so far are four options: Do nothing, accept that two classes offering caching functionality are present. Create a Facade class to stick Zend's interface onto Doctrine's caching implementation. Option 2, the other way around - create a Facade to map Doctrine's interface on a Zend Framework backend. Use multiple-interface-inheritance to create one interface to rule them all, and pray that there aren't any overlaps (ie: if both have a "save" method, they'll need to accept params in the same order due to PHP's lack of proper polymorphism). What option is best, or is there a "None of the above" variant that I'm not aware of?

• Boundary conditions for testing

  - by Loggie

  Ok so in a programming test I was given the following question. Question 1 (1 mark) Spot the potential bug in this section of code: void Class::Update( float dt ) { totalTime += dt; if( totalTime == 3.0f ) { // Do state change m_State++; } } The multiple choice answers for this question were. a) It has a constant floating point number where it should have a named constant variable b) It may not change state with only an equality test c) You don't know what state you are changing to d) The class is named poorly I wrongly answered this with answer C. I eventually received feedback on the answers and the feedback for this question was Correct answer is a. This is about understanding correct boundary conditions for tests. The other answers are arguably valid points, but do not indicate a potential bug in the code. My question here is, what does this have to do with boundary conditions? My understanding of boundary conditions is checking that a value is within a certain range, which isn't the case here. Upon looking over the question, in my opinion, B should be the correct answer when considering the accuracy issues of using floating point values.

• Website Design; SEO Dilemma

  - by lemonpole

  Okay so I designed a website for a restaurant and the design is aimed mostly to entice the viewer by using images of the restaurant's platters and foods. Not to say that text is totally non-existent but the design makes it hard to have enough keywords. Most keywords are found in the ALT attribute of image tags and a couple of headers. The reason as to why I am in this dilemma? I'm still new to web development and at the time I made the design, I didn't really know much about SEO. So I come here in search of help because I have an idea... Would it be good practice to have hidden SPAN blocks that would help me fill with keywords? For example a hidden SPAN would have text in bold to help with SEO. Of course, I will play it safe and not exploit this technique if it works. I have searched that this may be considered spamming by search engines and some companies are taking measures to prevent this. Thanks in advance!

• A key principle of Scrum...

  - by AndyScott

  "A key principle of Scrum is its recognition that during a project the customers can change their minds about what they want and need (often called requirements churn), and that unpredicted challenges cannot be easily addressed in a traditional predictive or planned manner. As such, Scrum adopts an empirical approach—accepting that the problem cannot be fully understood or defined, focusing instead on maximizing the team’s ability to deliver quickly and respond to emerging requirements." I have been working in a SCRUM environment, with 4-6 week cycles, for about 6 months now and have been very pleased with the impact that it has had on my life (regular work hours, seeing my family, etc).  But was looking up the criteria for a 'Certified Scrum Master' and came across the SCRUM definition on Wikipedia, and started reading the actual definition.  My first thought was "hey, this development methodology actually allows you to deal with what happens in the real world (i.e. customers changing requirements); but is this "selling out" on solid requirements? I understand that this works in the environment that I am currently working in, where there are deep pockets paying the bills, and also making the descisions on what requirements to change / impliment; but is this a recepie for success in smaller or simply more budget concious environments?  Having the ability to be completely flexible when the client wants the product changed.   The more I think about it, the more I feel that SCRUM development may be better suited for an environment where a team is taking over a project from another team (bringing some outside development in-house or something of that ilk), as opposed to ground up development. What do you think?

• Convert old videos to have smaller sizes

  - by Tim

  I have some videos from a few years ago,with various formats, such as avi, mpg, wmv, rm, rmvb, .... Their sizes are huge(more than 500 MB, and sometimes 1GB). Given there may likely be some advance in data compression, I would like to know which file formats and compression methods are recommended these days, by the standard that without losing obvious data, while achieving big size reduction. How can I perform the file format conversion and data compression in Ubuntu 12.04? Command line and batch ways would be the most convenient, although GUI ways are also appreciated. Thanks and regards!

• Why are some web clients requesting a page named "cache"?

  - by Toto

  We see errors like this in the apache error log: [Thu May 17 14:32:35 2012] [error] [client 192.168.1.1] File does not exist: /home/www-data/mywebsite.com/r/cache, referer: http://www.mywebsite.com/r/1010 It is strange because: There is no reference in the code/url about a folder/file "cache". The folder/file "cache" does not exist The client is randomly trying to access a "cache" folder everywhere on the website. It is always trying to access the folder/file "cache" following this pattern: Pattern: /level1/.../levelwhatever/filename (referer) /level1/.../levelwhatever/cache We run a LAMP (Debian stable: PHP 5.3.3-7+squeeze9. We also use APC 3.1.3p1). We use Google Analytics and AdSense. We do not know how to reproduce the problem. Note: I replaced the user's IP in the code for privacy.

• When HDD becomes full, how to create a symbolic link to the data store on another disk?

  - by Brij Raj Singh

  I have a Linux Ubuntu machine which has an X GB hard disk. There is folder, say, /opt/software/data. The disk /dev/sda1 is almost full and I have attached another disk at /dev/sda2 which is mounted at /hdd2. Is it possible for me to link the folders /opt/software/data with /hdd2/software/data so, that every file get stored in the /hdd2/software/data but may be referred from the /opt/software/data? I can't do a reinstall of the software that creates this data, to change the default location of storage.

• How do sites avoid SEO issues / legalities with subdomain unique ids?

  - by JM4

  I was looking through a few websites recently and noticed a trend I'm not sure I understand. Sites are creating unique referral URLs for customers in the form of: http://customname.site.com (If somebody were to use http://www.site.com/customname it would function the same way). I can see the sites are using 302 redirects at some point using Google Chrome then doing some sort of htaccess redirect, taking the subdomain name (customname) and applying it as a referral parameter then keeping in session during the entire process. However, there must be thousands of these custom URLs that people are typing in. How are each one of these "subdomains" not treated as separate URLs which in turn are redirected to the same page (in short, generating tons of links all pointing to the same page which Google would normally frown upon)? Additionally, the links also appear on the site themselves as clickable links so I'm not sure how these are not tracked. Similarly, the "unique" url is not indexed or cached in any Google search results. How is this capability handled? It does NOT highlight the referral aspect, but a true example of this is visiting http://sfgiants.com which does a 302 redirect to the much longer proper San Francisco Giants MLB homepage. I am wondering how SFgiants.com is not indexed (assuming that direct shortened link appears on several MLB pages)? 1 - I know these are 302 redirects, I can see this on the sites network flow. 2 - These links do in fact appear on the page itself because in some areas (for example, the bottom of the page may say: send this page to a friend! http://name.site.com/ which in turn would again redirect to something like http://www.site.com?id=name so the id value could be stored in session

• Run Win7 Guest (raw disk) in Ubuntu (which was installed as Dual Boot on existing Win7)

  - by kingdango

  I installed Ubuntu 12.10 on top of Win 7 as a dual boot (awesome!). I'm hoping to use VirtualBox to run my original Win7 instance as a guest OS under Ubuntu. I found this existing question and followed the directions to no avail. I can get the VMDK file created but when I run it I just get a blank black screen with no additional information and Windows never loads. I see no HD activity or anything that would indicate it's loading. I used this command to create the VMDK file: VBoxManager internalcommands createrawvmdk -filename ~/.VirtualBox/Win7Native.vmdk -rawdisk /dev/sda3 It looks like everything was created correctly but I just get a blank screen when I run the VM. I do get this warning when I boot the VM: VirtualBox - Warning The virtual machine execution may run into and error condition as described below... The medium '/home/XXX/.VirtualBox/Win7Native.vmdk' has a logical size of 583GB but the file system the medium is located on can only handle up to 16GB in theory. We strongly recommend to put all your virtual disk images and the snapshot folder on a proper file system (e.g. etc3) with a sufficient size.

• Multi Threading - How to split the tasks

  - by Motig

  if I have a game engine with the basic 'game engine' components, what is the best way to 'split' the tasks with a multi-threaded approach? Assuming I have the standard components of: Rendering Physics Scripts Networking And a quad-core, I see two ways of multi-threading: Option A ('Vertical'): Using this approach I can allow one core for each component of the engine; e.g. one core for the Rendering task, one for the Physics, etc. Advantages: I do not need to worry about thread-safety within each component I can take advantage of special optimizations provided for single-threaded access (e.g. DirectX offers a flag that can be set to tell it that you will only use single-threading) Option B ('Horizontal'): Using this approach, each task may be split up into 1 <= n <= numCores threads, and executed simultaneously, one after the other. Advantages: Allows for work-sharing, i.e. each thread can take over work still remaining as the others are still processing I can take advantage of libraries that are designed for multi-threading (i.e. ... DirectX) I think, in retrospect, I would pick Option B, but I wanted to hear you guys' thoughts on the matter.

• After deleting a local machines offline file cache, the same user's "my documents" no longer redirects to the network location.

  - by stead1984

  One of my apprentices was tasked with clearing out unused local profiles and clearing the offline file cache. After he cleared the offline file cache and rebooted the machine, he would log in as himself and no longer have his "my documents" redirected to the set network location. More over this seemed to then affect ANY other networked machine he logged into, except his own laptop. All our standard workstations run Windows XP Service Pack 3, the apprentice's laptop runs Windows 7 Professional. I can understand how clearing the offline file cache after deleting old local profiles could cause this issue but draw a complete blank as to why it would affect all networked machines. It's a strange one so this question may be a little hard to understand so any questions or further understanding required please ask.

• Limiting my heavy thinking to my job [closed]

  - by Robin Castlin

  This might be a weird problem which is only to a half relevant to actual programming, but hopefully there are people here that knows what I'm talking about. Basicly I'm proud of how I can deal with coding problems and fix them in short notice and many other aspects like building new systems and such. I'm fast on finding solutions and I often think about the impact my changes does to existing systems and so on, therefor preventing problem from arising at all and such. I am simply happy with how my mind operates when it comes to programming and I wouldn't want to change it at all. The problem, however is when I'm not programming. I find myself rather limited in social situations. I can't determine if it is through programming, but I sometimes think way to much about the consequences when it comes to being social. I know from own experience that most times you earn by not thinking about consequences, but it's hard for me not to. Often my friends tells me "I think too much" and even though I agree, I can't seem to change this behavior. My brain wants to think, and it likes to overthink simple stuff. Does anyone recognize the bad habit of not leaving advanced thinking at work, and in what way do you deal with it? If this isn't a suitable place to ask this question, I apologize and hope you may point me to the right site.

• Why does deleting from the command line take significantly less time than from a GUI?

  - by Jordan Plahn

  So this is probably the dumbest question you'll read today, but it's something I just wondered about as I was deleting a dozen or so images from my computer. With a quick rm -rf command on the directory's contents, all the images were gone in a snap. When I drag the same dozen or so images to a trash can/recycle ban, it takes sometimes 10 seconds or more. Now I'm sure some of it comes from the overhead of the GUI and such, and some of it may be the fact that the file still "exists" in some form if it's put into the recycle bin, but is there anything else that accounts for such a huge time disparity? Are "rm" and "delete" just such fundamentally different commands so I'm trying to compare apples and oranges? Enlighten me, please!

• Help looking before I leap! I need expert guidance...

  - by Ellen Reddick

  27" iMac running win7 under bootcamp (slick! ). I have Access 2003 program with files linked through ODBC used by 4 installations (all with Access 2003 installed). I want to buy Access 2010 and try it under virtual PC (under Bootcamp). Will it work (since I have to install the ODBC drivers)? If I decide after this trial that I like what it does, can I then install it under the Windows 7 bootcamp partition (with or without uninstalling the virtual PC) without using up the 2nd allowed installation? Also, I see that MS allows an Office Pro 2010 trial download good for 60 days. Would this work in Windows 7 Virtual PC and would it be a better way to go, followed by a legitimate purchase of Access 2010 for the Windows 7? This is not an Access programming question--I realize there may be some tweaks necessary in the program to run it under 2010 and I can handle that part.

• how to calculate intersection time and place of multiple moving arcs

  - by user20733

  I have rocks orbiting moons, moons orbiting planets, planets orbiting suns, and suns orbiting black holes, and the current system could have many many layers of orbitage. the position of any object is a function of time and relative to the object it orbits. (so far so good). now I want to know for a given 2 objects(A,B), a start time and a speed, how can I work out the when and where to go. I can work out where A and B is given a time. so i just need. 1: direction to travel in from A to B(remember B is moving(not in a straight line)) 2: Time to get to b in a straight line. travel must be in a straight line with the shortest possible distance. as an extension to this question, how will i know if its better to wait, EG is it faster to stay on object A and wait for a hour when the objects may be closer, than to set off from A to B at the start. Cheers, it hurt my brain.

• shrink ext4 partition

  - by user276851

  My question is similar to Move ext4 partition, but the challenge I couldn't figure out is how to shrink a partition from the start. So suppose originally the partition (with raid) is like this. (************** /dev/md127 ***************) After resizing, I want to achieve like this. (*** unallocated ***)(**** /dev/md127 ****) Note, I cannot use gparted, and parted does not support ext4. The commands I have tried so far, % resize2fs -p /dev/md127 1676G # <== This is good. % lvreduce -L 1676G /dev/md127 Path required for Logical Volume "md127" Please provide a volume group name Run `lvreduce --help' for more information. Failed here, I guess it may be because the underlying partition is primary and the lvreduce only works on logical? Anyway, no idea. Then after that, I am thinking to create another partition right after this one, copy the data to that partition, and remove this one, like. 1. (************** /dev/md127 ***************) 2. (**** /dev/md127 ****)(*** new partition **) 3. (*** unallocated ****)(**** /dev/md127 ****) Thanks for the help.
