  • What is your unique programming problem-solving style? [closed]

    - by gcc
    Everyone has their own styles and technique for approaching and solving real world problems. These distinguish us from other people or other programmers. (Actually, I think it make us more desirable as programmers and improves computer science) To improve, we read a lot of books; for example, programming style, how to solve problems, how to approach problems, software and algorithms, et al. Can I learn your technique? In other words, if someone gives you a problem, at first step, what are you doing to solve it? I want learn the style in which you approach, analyze, and solve a problem. EDIT: every programmer is a unique instance; each of us approach problems and converge on solutions in our own... idiomatic manner. This manner is sometimes a quirk of training, a bias of tools, but often it is an insightful nugget, a little golden hammer that cracks nuts just slightly faster then others. When answering, give your general approaches but also take a moment to identify how you look at things in ways that your peers do not. Let's call this your Unique Solving Perspective, or USP.

  • New power supply and now HDDs are not recognized.

    - by Michael
    So I upgraded to a new X4 ULTRA power supply that was recommended to me by a local TigerDirect store. After installing it along with a new liquid cooling system, I booted it up and it automatically fried my CD Drive. After that I noticed that the OS wouldn't start and figured out that none of the 4 HDDs in my computer were being recognized by the BIOS. I feel them spool at a steady pace and have tried new cables and connections but to no avail. I triple checked all of the connections and cables and have no idea what is wrong. This isn't the first time I changed a PS or CPU cooling system but I am at a dead end. Any ideas, aside from buying a USB HDD reader and seeing if they are all fried? Also, this is a stock Gateway mobo with the mobo USB connections already dead. Could the new PS have fried the SATA connections??

  • How to make a folder (D:\xyz) accessible to only me in Windows-XP?

    - by claws
    Hello, I'm using Windows XP on my lab computer. There is a global folder (d:\xyz). This is my folder and I want this folder to be accessible to only me. It should be invisible even if it is visible they shouldn't be able to open this folder. For now my account has administrative privilages. After few days, I don't know if the Admin lets me have these privilages or not. I heard that soon our XP machines will be upgraded to either vista or windows 7. Will the method of making folder in accessible change for other Windows OSes? How to accomplish this?

  • Copying Firefox profile

    - by ChrisW
    My computer (well, Windows XP) failed. I got everything off the HD, including my Firefox profile, which I especially wanted because I had lots of open unsaved tabs in my current session (yes, I know that's bad practice!), but also to rescue bookmarks etc. I've now got Windows 7, and reinstalled Firefox. I've read the instructions on the Firefox website about creating new profiles, and I'm not sure they're very intuitive. It says that you can copy all the contents from an old profile into a new 'default' one, which I have done (http://support.mozilla.org/en-US/kb/back-and-restore-information-Firefox-profiles). However, when I open Firefox, the data from this profile isn't being used and Firefox doesn't seem to recognise the data that's there. What am I doing wrong?!

  • Error burning DVD using Devede on Ubuntu 9.04

    - by tim-myers
    I'm trying to burn a DVD in DeVeDe under ubuntu -- on my computer it's already in DVD format (a VIDEO_TS folder) but when I try and drag it into DeVeDe it says "Some files weren't video files. None added." From looking at it, all the files look like they belong there, just from doing this a few times already and seeing all the files contained in a DVD. The file extensions in the folder are: VOB BUP IFO and the files are all named like VTS_02_1.VOB. I have tried excluding the IFO files when dragging them into DeVeDe but get the same error. Is the problem in the types of files in the DVD data or is the DVD corrupt?

  • Macbook cannot see specific wireless network after being connected to it for a while

    - by donut
    Okay, so there's a single wireless network that my laptop has troubles with. My Macbook Pro used to be fine with it until it changed to using channel 13 (or 11?). Since then, after being connected to it for a while it disappears from my laptop's view. Other networks are showing up fine and other computers (including several Macs) have no troubles connecting to this network. If I clear my system cache using Onyx and then restart (sometimes a couple times) my laptop can see and connect to it again. But it seems that if I disconnect and try reconnecting I have to clear my cache again. One thing to note is that if I put my computer to sleep while connected to this network it has no problems reconnecting on wake up. I've got a 15" Macbook Pro 2,2 with Leopard 10.5.8.

  • Setting up a static IP address (public) in Ubuntu

    - by ycseattle
    I have a business class internet connection and need to setup a static ip address for a machine. I did a search online and only find how to setup static local ip addresses (like 192.168..). I tried the same technique, and only setup the ip address and netmask, but after restart networking the computer could not connect to the outside world. This is what I did: 1) edit /etc/network/interfaces iface eth0 inet static address 173.10.xxx.xx netmask 255.255.255.252 2) edit /etc/resolv.conf search wp.comcast.net nameserver xx.xx.xx.xxx nameserver xx.xx.xx.xxx 3) restart network sudo /etc/init.d/networking restart Now the last step didn't report error, ifconfig shows the ip address was set, but this server cannot connect to outside world, ping google.com and reports "unknown host google.com". Any ideas?

  • DSL connection not working in 10.04

    - by Mussnoon
    I use a wired PPPoE connection to connect to the Internet. What I need to do on Windows to connect to it is put in static IP address, gateway, subnet mask and DNS servers for my LAN card. Next I have to create a dialer for a PPPoE connection, put in my user name, the service name and the password, and "dial" this connection. And it works fine. On Ubuntu 10.04, however, I have tried setting things up in a similar fashion - put in all static addresses for the "automatic" wired connection, then put in user name, service name, password for a "DSL" connection. It worked for a while, then stopped. I have tried putting in all the details within the DSL configuration dialog, same thing happened - it worked for a while, then stopped. I have tried deleting the ethernet connection and only keeping the DSL one with all the numbers put in place, same thing happened - it worked for a while, then stopped. Each of the times, when it connected, it connected randomly, after trying a few times, and either stopped working within a few minutes, or after I had rebooted. I have deleted and remade the connection dozens of times - even with different names, but nothing seems to be working. I have also tried pppoeconf from the terminal, didn't work. I have checked /var/log/kern.log, but nothing changes in the file when I try to connect. I have also checked /sbin/route, but gedit can't even open it (says it can't figure the character encoding...). The "connection established" notification pops up from the top right corner, the same way as when the computer is actually connected to a network. Can anyone figure what's wrong and how it can be solved?

  • .vob to h.264 MP4 Files - Worth The Effort?

    - by harper89
    When I was doing the converting to digital format a while back I chose .VOB due to no quality loss. However recently I have been informed of this h.264 compression method. Time is not an issue here, I don't mind waiting for conversions etc. I also understand that any sort of compression will reduce quality. To test I converted a 4GB .VOB to a .mp4 using h264 in handbrake and the quality loss was very very very hard to notice. From what I have understood through research Space = .mp4(h.264) Quality = .Vob Playback = Both equally supported? But these concerns have yet to be answered: My comparison was done on a computer monitor, would the quality loss be substantially noticable if I purchased a 50 inch TV in the future? Is this type of file highly supported? (I don't want to experience incompatible players) What other issues could a conversion of files such as this cause in the future?

  • Macbook Pro 13" Retina (10,2): Keyboard and Touchpad don't work

    - by Dirk
    I'm dealing with Ubuntu since about 5 years and installed it on several laptops. Now I'm stuck when trying to install Ubuntu 12.04.1 on a brand new Macbook Pro 13" Retina (10,2). I sucessfully can start Ubuntu from an USB stick, the Ubuntu desktop is visible, a mouse cursor is visible. But there is no respond to keyboard or touchpad input. So I cannot really install Ubuntu on the Macbook. The details of my approach: Prepare an empty USB stick Download "ISO 2 USB EFI Booter for Mac" and copy the file bootX64.efi to the USB drive as /efi/boot/bootX64.efi. Download Ubuntu 12.04.1 Desktop for Mac from http://cdimage.ubuntu.com/releases/1-amd64+mac.iso and copy the iso the USB drive as /efi/boot/boot.iso Put the USB stick into the Macbook Press and hold the "alt" button while switching the Macbook on Select "EFI Boot" from the boot menu that appears and press the Return / Enter key Immediately a black terminal screen appears with the headline "Welcome to the Ubuntu ISO << - EFI booter". 30 seconds later the familiar Ubuntu startup graphics screen is showing. Further 20 seconds later Ubuntu has started and the desktop is visible - in wonderfully fine resolution Now the computer does not respond to any actions on the touchpad nor the keyboard Who did install Ubuntu on this Macbook Pro 13" Retina (10,2) successfully? On this site https://help.ubuntu.com/community/MacBookPro this unit is not listed yet, anyway. Any help would be greatly appreciated! Dirk

  • Text Terminal Hardware (for Linux)

    - by DLH
    Is there any way to obtain a hardware text terminal (preferably small in size) with a screen and a keypad to connect to a Linux machine (preferably via usb)? I'd like to be able to log into a command line and do some work there while simultaneously running a graphical environment on the main display. It seems like there should be some kind of lcd screen and qwerty keypad device designed for this purpose. Does this exist, and how do I get one? Edit: I'd be happy with a small networked device as well, as long as I could get a remote terminal into my computer.

  • pdflatex reads .eps files saved in OS/X, but not in Ubuntu

    - by David B Borenstein
    Sorry if this is a stupid question; I'm a newbie. I am preparing a manuscript in LaTeX. The journal (Physical Biology, an IOP publication) requires that figures be saved in .eps format, so I am trying to do that. However, I cannot get my LaTeX file to build when I have generated the .eps files on my Ubuntu computer. If I save the images on my Mac, the file build just fine. So far, I have tried saving images in ImageJ, FIJI and Inkscape. The same problem occurs in all three. When using kile, I get the following error: /usr/share/texmf-texlive/tex/latex/oberdiek/epstopdf-base.sty:0: Shell escape feature is not enabled. In TexWorks, the error is different, but still there: Package pdftex.def Error: File `./figures4/figure4a-eps-converted-to.pdf' not found. Now, if I fire up Inkscape, FIJI or ImageJ on OS/X, everything works fine. The Mac also can't build with the Ubuntu-saved images. The images generated on the Ubuntu machine open fine using Document Viewer. I am building the same LaTeX file on both computers, with the exact same results. The header of my LaTeX file is: \documentclass[12pt]{iopart} \usepackage{graphicx} \usepackage{epstopdf} \usepackage{parskip} \usepackage{color} \usepackage{iopams} And then the code for the figure is: \begin{figure} \center{\includegraphics[width=4in] {./figures4/figure4a.eps}} \footnotesize{\caption{ \label{fig:4a} (4a) lorem ipsum dolor sic amet.}} \end{figure} I'd be happy to send an example of both .eps files. Again, sorry if this is a dumb question. I tried everything I could think of before posting here. Thanks, David

  • Dual Screens with Widescreen monitors?

    - by nmuntz
    I want to build a new computer and purchase new monitor(s). At my old job I had two 20" 4:3 and I absolutely loved this setup. However, the stores in my country only seem to have widescreen monitors nowadays, and the only 4:3 LCDs i have been able to find are 17". My question is: Do widescreens suck for using them as dual monitors? Can anyone with this setup comment on their experience with having multiple widescreen monitors? Would it be better to get three 17" 4:3 LCDs instead of two widescreens? If i go with widescreens, should i go with the smallest ones i can find? Purchasing a single big widescreen monitor is not an option for me, since being able to maximize an app on a specific area of the screen is a must have for me and im not willing to use "hacky" apps for this purpose that do a crappy job. Thanks in advance for your advise.

  • No audio input deviced are installed

    - by Meowbits
    If I go to Sound Recording Devices and it says "No audio devices are installed" If I click to set up a microphone I get an error "Wizard could not launch, No audio input device found, make sure your audio hardware is working properly and check your audio configuration in the Audio Devices and Sound Themes control panel. Where can I get an audio input device? I just want something so I can actually use the microphone on my headset. This is ridiculous. I have tried to look for any file but I simply cannot find a way to add an audio input device... I really do not want to format my computer just for this problem but I am starting to feel like that is the only option I have. I have the latest chipsets

  • The Hot-Add Memory Hogs

    - by Andrew Clarke
    One of the more difficult tasks, when virtualizing a server, is to determine the amount of memory that Hypervisor should assign to the virtual machine. This requires accurate monitoring and, because of the consequences of setting the value too low, there is a great temptation to err on the side of over-provisioning. This results in fewer guest VMs and, in fact, with more accurate memory provisioning, many virtual environments could support 30% more VMs. In order to achieve a better consolidation (aka VM density) ratio, Windows Server 2008 R2 SP1 has introduced what Microsoft calls ‘Dynamic Memory’. This means that the start-up RAM VM memory assigned to guest virtual machines can be allowed to vary according to demand, changing dynamically while the VM is running, based on the workload of applications running inside. If demand outstrips supply, then memory can be rationed according to the ‘memory weight’ assigned to the guest VM. By this mechanism, memory becomes a shared resource that can be reallocated automatically as demand patterns vary. Unlike VMWare’s Memory Overcommit technology, the sum of all the memory allocations to each virtual machine will not exceed the total memory of the host computer. This is fine for applications that are self-regulating in their demands for memory, releasing memory back into the 'pool' when not under peak load. Other applications however, such as SQL Server Standard and Enterprise, are by nature, memory hogs under high workload; they can grab hot-add memory whilst running under load and then never release it. This requires more careful setting-up and the SQLOS team have provided some guidelines from for configuring SQL Server in virtual environments. Whereas VMWare’s Memory Overcommit is well-proven in a number of different configurations, Hyper-V’s ‘Dynamic Memory’ is new. So far, the indications are that it will improve the business case for virtualizing and it is probably a far more intuitive technology for the average IT professional to grasp. It is certainly worth testing to see whether it works for you.

  • Why would my router have different MAC addresses for IP and IPv6 transactions?

    - by user329161
    Today I was using tcpdump and I noticed my computer was having IPv6 traffic with a particular MAC address that I could not match with an IP using nmap or arping. After looking at the tcpdump logs a little more closely, I figured out it was another MAC address my router was using but exclusively for IPv6 traffic. 22:49:01.936830 90:0d:cb:ff:31:91 (oui Unknown) > 33:33:00:00:00:01 (oui Unknown), ethertype IPv6 (0x86dd), length 158: fe80::920d:cbff:feff:3191 > ip6-allnodes: ICMP6, router advertisement, length 104 Why would a router offer a different MAC address for IPv6?

  • new user account

    - by Donna Crain
    Hi I hope someone can help me... I accidentally renamed my own user name on my mac running OS X 10.4.11 and tried renaming back to what it was but now I have two accounts (the one I want to use which has all my preferences, applications, mail boxes, etc etc) is it possible to copy my settings from my original into this new user name? When I open my computer it defaults to this new account but everything is setting up from new and I just need to get access to all my work documents, mail settings etc. If there is anyone who could help out, I would be very grateful. Thank you in advance.

  • How to Recover that Photo, Picture or File You Deleted Accidentally

    - by The Geek
    Have you ever accidentally deleted a photo on your camera, computer, USB drive, or anywhere else? What you might not know is that you can usually restore those pictures—even from your camera’s memory stick. Windows tries to prevent you from making a big mistake by providing the Recycle Bin, where deleted files hang around for a while—but unfortunately it doesn’t work for external USB drives, USB flash drives, memory sticks, or mapped drives. Luckily there’s another way to recover deleted files. Note: we originally wrote this article a year ago, but we’ve received this question so many times from readers, friends, and families that we’ve polished it up and are republishing it for everybody.

  • DDWRT or similar as repeater in a network.

    - by Quantumplation
    I have a friend with sever connection issues due to her wireless router being on the bottom floor of her house, and the computer being a story or two away. I have several old Linksys routers lying about, one of which is currently running DDWRT for my network. Would it be a good idea (effective) to configure one of these routers as a wireless bridge of some kind in an intermediary floor to improve her connection? Is there any specific configuration beyond the standard DDWRT setup that I would need to do? Thanks for your help. =)

  • SQL 2008 Reporting Services Report Manager blank on Win 7

    - by Daniel Root
    I have installed SQL Server 2008 Reporting Services on my development laptop running windows 7. When I browse to the report manager, only the header is shown. The content pane is blank, and there is no 'Site Settings' option, New Folder options, etc. I found plenty of similar stories about SQL 2005, and then the fix was to manage permissions in the virtual directory in IIS. However, in 2008, there is no virtual directory - RS manages this outside of IIS. Per other serverfault articles, I've tried the following: adding my account to the reporting services group changing the service to run as local system made sure localhost was trusted site in IE ran IE as admin installed SQL Server 2008 SP1 There are no errors in the event viewer. Perhaps related, if I browse to the webservice, I also get the error: The permissions granted to user 'Computer\User' are insufficient for performing this operation. (rsAccessDenied)

  • Programming by dictation?

    - by Andrew M
    ie. you speak out the code, and someone else across the room types it in Anyone tried this? Obviously the person taking the dictation would need to be a coder too, so you didn't have to explain everything and go into tedious detail (not 'open bracket, new line...' but more like 'create a new class called myParser that takes three arguments, first one is...'). I thought of it because sometimes I'm too easily distracted at my computer. Surrounded by buttons, instant gratification a click away, the world at my fingertips. To get stuff done, I want to get away, write my code on paper. But that would mean losing access to necessary resources, and necessitate tedious typing-up later on. The solution? Dictate. Pros: no chance to check reddit, stackexchange, gmail, etc. code while you pace the room, lie down, play billiards, whatever train your brain to think more abstractedly (have to visualize things if you can't just see the screen) skip the tedious details (closing brackets etc.) the typist gets to shadow a more experienced programmer and learn how they work the typist can provide assistance/suggestions external pressure of typist expecting instructions, urging you to stay focussed Cons might be too hard might not work any better rather inefficient use of assisting programmer need to find/pay someone to do this
