• How can I get my monitor's maximum resolution without the proprietary AMD graphic driver installed?

  - by Venki

  I am using Ubuntu 14.04. I have an AMD Radeon 5570 HD graphic card. Actually, the default open source REDWOOD drivers aren't allowing me to choose my monitor's maximum screen resolution(which is 1366 x 768). I just have two resolutions displayed which are 1024x768 and 800x600 . If I give the command : xrandr -s 1366x768 then the output is: Size 1366x768 not found in available modes So just for the sake of getting 1366x768 resolution I am forced to install the proprietary graphic driver that AMD gives me from its site. But if I install it(which itself is quite a problem-prone process), I undergo a lot of 'inconvenience'. Sometimes after an OS update, the driver crashes unity. Then I will have to uninstall that driver from a tty and google around for a solution. Also I encounter screen tearing problems occasionally. In addition I also cant see my login screen(See this question which states this particular problem). The main problem is AMD does not update its driver as quick as Ubuntu updates its OS. This is quite irritating. So, I want the maximum resolution(and performance) that my graphics card and monitor can give me without installing the 'problematic' proprietary graphic card driver that AMD gives. Is this possible? Suggestions please. Thanks in advance.

• Deleting slow on X11 emacs

  - by Malvolio

  I'm running GNU Emacs 21.4.1 on a (remote) remote Linux ((CentOS) box, using my MacBook as the X-server. Works fine, unless I try to delete a word, line, or region. Then it locks up for 30 seconds or so. It sounds like a minor thing, but you realize how often you do a delete when you have to stop for 30 seconds every time. My theory is that Emacs is trying to put the text in the X-server cut-and-paste buffer, which is trying to put it in the OSX cut-and-paste buffer and somewhere along the way, the process is blocked until it times out. (My only evidence for this theory is (a) copy-region behaves the same way and (b) deleted text doesn't show up in the buffer.) Any suggestions appreciated. Edit: (setq interprogram-cut-function nil) fixed me right up. Which makes perfect sense. Thanks, Trey.

• windows 8 + Ubuntu dual boot

  - by Jack Yuan

  I installed Ubuntu 13.04 on Windows 8. Yes I can access both of them, but the process is kind of long. In BIOS, EFI is for Windows 8, legacy support is for Ubuntu. If I choose EFI first, the startup just go straight to Win8 without offering me a choice. If I choose legacy first, the starup will offer me a choice between win8 and ubuntu. But I can only choose Ubuntu. If i choose win8, there will be a mistake(file missing under configuration). That is to say, every time i wanna switch to another OS, I have to go into BIOS and change the priority settings. I heard something about secure boot might be the cause of this situation. But the thing is that there is not even an option called "secure boot" in my BIOS, which means i cannot disable it. All I want is that an option menu appears everytime i turn on my computer so i can easily choose what OS I want for today. Can anyone help me plz? Thank you very much!!

• Windows 7 Pro x64 suffering from insomnia

  - by gemisigo

  My Win 7 Pro x64 is unable to enter sleep mode. Pressing the sleep button results in strange state where the computer starts entering the sleep mode, the display is turned off but then the whole process stops, it does not switch off the hdd, the keyboard still responds to numlock/capslock, but the display does not on anymore. I have to cut power and restart. If I remove everything (wireless mouse, external hdd, usb hub, etc.) it does enter sleep mode, but if there is something left, it does not, though every one of them has "Allow the computer to turn off this device..." checked and "Allow this device to wake the computer" unchecked. Why does it not work? It was working properly in the RC.

• Quick and Good: ( Requirement -> Validation -> Design ) for self use?

  - by Yugal Jindle

  How to casually do the required Software Engineering and designing? I am an inexperienced developer and face the following problem: My company is a start up and has no fix Software engineering systems. I am assigned tasks with not very clear and conflicting requirements. I don't have to follow any designs or verify requirements officially. Problem: I code all day and finally get stuck where requirement conflicts and I have to start over again. I can-not spend a lot of time doing proper SRS or SDD. How should I: List out Requirements for myself. (Not an official document) How to verify and validate the requirements? How to visualize them? How to design them with minimum effort? (As its going to be with me only) I don't want to waste my time coding something that's gonna collapse according to requirement conflict or something! I don't want to compromise with quality but don't want to re-write everything on some change that I didn't expected. I imagine making a diagram for my thought process that will show me conflict in the diagram itself, then finally correcting the diagram - I decide my design and structure my code in terms of interfaces or something. And then finally start implementing my design. I am able to sense the lack of systematic approach, but don't know how to proceed! Update: Please suggest me some tools that can ask me the questions and help me aggregate important details. How can I have diagram that I talked about for requirement verification?

• Complex string matching with fuzzywuzzy

  - by That1Guy

  I'm attempting to write a process that matches obscure strings to a single 'master string' for further processing. I have a lot of data that looks something like this: Basketball Basket Ball Football BasketBallR BBall BBall - r FootB ...and so on. These need to be mapped to a master record like so: Basketball = Basket Ball, BBall Basketball - R = BasketBallR, BBall - r I also have instances of data resembling this format: Football -r FootBall - r-g/H,Q,HH These situations need to be separated into different categories before being mapped. For example FootBall - r-g/H,Q,HH should be: Football - r Football - g Football - H Football - Q Football - HH At this point, it still needs to be mapped to a master record... I've tried several different combinations of fuzzywuzzy matching methods, Levenshtein Distance measurements, regex, etc. and can't seem to find a reliable method to logically associate different naming styles of a single item with a master name. I'm throwing my hands up in desperation. Are there any existing python resources than can help sort out my problem? Are there other options? Can anybody point out an obvious option that I might have overlooked? Basically, any suggestion, solution, resource or alternative method is greatly appreciated.

• Pull Request Conversations, Inline Diff Enhancements

  [Do you tweet? Follow us on Twitter @matthawley and @adacole_msft] We deployed a new version of the CodePlex website today. Pull Request Conversations Previously, the only way for project members and users who submitted pull requests to converse was via e-mail. This complicated the review process and made conversations isolated and difficult to track. For this release, we’ve added functionality that enables you to have those same conversations within the pull request page. When you view a pull request, you’ll now see “Comments” and “Changes” tabs, with current comments displayed. Inline Diff Enhancements We tweaked the inline diff experience to make it easier to traverse diff blocks. When you open up the inline diff experience, you’ll now see up and down arrows. To move between the diff blocks, you can use those arrows or utilize the available keyboard shortcuts. Lastly, we have also brought the inline diff experience to the source control changes page for project and fork changesets. You can see both enhancements live by viewing the associated pull request or changeset changes on WikiPlex. The CodePlex team values your feedback. We are frequently monitoring Twitter, our Discussions, and Issue Tracker. If you have not visited the Issue Tracker recently, please take a few minutes to suggest or vote on a feature you would like to see implemented.

• A Web Service to collect data from local servers every hour

  - by anilerduran

  I'm trying to find a way to collect data from different servers around the world. Here are the details: There is only one single PowerShell script on servers that encrypts data (simple csv file) and sends with preferred method (HTTP/HTTPS Post could be) There is no more control on that servers. Can't install any service, process etc. Just I can configure script to execute every hour. This script also will have encrypted username/password/license key for every server. Script will compress data and send to me with these information. So I need a service (I'm not sure if Web Service is the rigth solution) on the cloud that will help me to: Will get data that is sent from servers using a method. Will authenticate request to recognize sender using license key/username/password and most importantly, Will redirect/send this filecab to my SQL Server on the cloud (Azure). Also it should seperate data according to customer information in license key. So every data for every customer will be stored in dedicated DB/Tables on my SQL All the processes above should be completed automatically. No way for manual steps. Question: A Web Service (SOAP or Restful) is the rigth solution for that?

• How can I send raw postscript to a remote printer via CUPS?

  - by Ash

  I have an ancient fax device with a printer interface that only accepts postscript level 1 documents formatted in a specific way. I only have access to this printer over the lpd:// protocol. I have some old documents from our previous system that work fine on our Unix machines, but they are altered somehow by CUPS when I use lp on our Linux system. The PDF files that end up in the print queue are significantly modified versions of the original, and although they still render in ghostscript, they don't do anything on the printer. I'm wondering if there's a way to tell CUPS "don't process this, just send it to the printer without modification", or whether there's a lpd client or procedure I could try?

• Installing CentOS 6.3 wrong hard drives order?

  - by Ken Tang

  I am trying to install CentOS 6.3 on new server that has 2xSSD and 1xHDD drives connected to mainboard's SATA ports by following order: SSD1 -> SATA1 SSD2 -> SATA2 HDD1 -> SATA3 On the installation process CentOS shows me hard drives by this order: /sda -> that is actually SSD2 /sdb -> HDD1 /sdc -> SSD1 It looks like CentOS assigns it randomly rather by the SATA connection order. My question is: What the order of drives /sd* depending on? And how can I change it to be by the order it connected to SATA? Thank you in advance!

• Designing communications for extensibility

  - by Thomas S.

  I am working on the design stages of an application that will a) collect data from various sources (in my case that's scientific data from serial ports), keeping track of the age of the data, b) generate real-time statistics (e.g. running averages) c) display, record, and otherwise handle the data (and statistics). I anticipate that I will be adding both data producers and consumers over time, and would like to design this application abstractly so that I will be able to trivially add functionality with a small amount of interface code. What I'm stumbling on is deciding what communication infrastructure I should use to handle the interfaces. In particular, how should I make the processed data and statistics available to multiple consumers? Some things I've considered: Writing to several named pipes (variable number). Each consumer reads from one of them. Using FUSE to make a userspace filesystem where a read() returns the latest line of data even if another process has already read it. Making a TCP server, and having consumers connect and request data individually. Simply writing the consumers as part of the same program that aggregates the data. So I would like to hear your all's advice on deciding how to interface these functions in the best way to keep them separate and allow room for extenstions.

• is wisdom of what happens 'behind scenes' (in compiler, external DLLs etc.) important?

  - by I_Question_Things_Deeply

  I have been a computer-fanatic for almost a decade now. I've always loved and wondered how computers work, even from the purest, lowest hardware level to the very smallest pixel on the screen, and all the software around that. That seems to be my problem though ... as I try to write code (I'm pretty fluent at C++) I always sit there enormous amounts of time in front of a text-editor wondering how every line, statement, datum, function, etc. will correspond to every Assembly and machine instruction performed to do absolutely everything necessary for the kernel to allocate memory to run my compiled program, and all of the other hardware being used as well. For example ... I would write cout << "Before memory changed" << endl; and run the debugger to get the Assembly for this, and then try and reverse disassemble the Assembly to machine code based on my ISA, and then research every .dll, library file, linked library, linking process, linker source code of the program, the make file, the kernel I'm using's steps of processing this compilation, the hardware's part aside from the processor (e.g. video card, sound card, chipset, cache latency, byte-sized registers, calling convention use, DDR3 RAM and disk drive, filesystem functioning and so many other things). Am I going about programming wrong? I mean I feel I should know everything that goes on underneath English syntax on a computer program. But the problem is that the more I research every little thing the less I actually accomplish at all. I can never finish anything because of this mentality, yet I feel compelled to know everything... what should I do?

• Interactive mode of PSExec not working for console application

  - by Focker

  I am trying to use PSExec to kick off a console application on a remote computer in an interactive state. When I run something like this: PsExec.exe -s -d -i 1 \\MyServer notepad.exe It launches Notepad just fine. If I then run this: PsExec.exe -s -d -i 1 \\MyServer C:\Temp\MyConsoleApp.exe It launches the command windows but doesn't do anything as far as I can tell. As in, when I run my console application locally, it displays a "heartbeat" every 5 seconds, but when I run it remotely, nothing is displayed in the command window. The .exe does show up as a process in Task Manager. Any ideas?

• Installing FreeNAS 8.3 problems

  - by osij2is

  I'm trying to install FreeNAS 8.3 on some desktop-level hardware (AMD Phenom + 890FX + 16GB) and I've been unsuccessful. I initially tried using a USB stick and followed the instructions on the FreeNAS site here. Making the USB was simple as the instructions laid out, but as soon as the USB is detected (during the boot process) some text appears and quickly vanishes and my machine reboots infinitely. After trying several different was to make the USB, I tried using a DVD-ROM but again, I had the same issue as the USB stick. This leads me to conclude that either a BIOS setting is incorrect but I have no idea which one. I've changed the BIOS to not "fast" boot per se, and I've correctly configured the boot order per USB stick and the DVD-ROM drive so I know that it's working. Have I missed anything that might be causing this problem? I'm not a FreeBSD/FreeNAS expert by any means.

• Ubuntu apt-get install (--download-only) executed from another machine on behalf of mine

  - by Maroloccio

  I have a server on a network segment with no direct or indirect access to the Internet. I want to perform an: apt-get install <package_name> Is there a way to somehow delegate the process of downloading the required files to another machine by exporting the server configuration so as to satisfy all dependencies while running: apt-get install --download-only <package_name> Can, in effect, apt-get install read a configuration from an exported archive rather than from the local package database? Can the list of packages to be downloaded be retrieved, along with an installation script to perform the installation, instead of the actual packages? (a further level of indirection which would help me schedule this with wget at appropriate times...)

• Trying to install PHP 5.2 on IIS/Win 2008 - Error 500

  - by Razor

  I have a fresh install of IIS 7 - I just added Web Platform Installer, and PHP 5.2 thru that. However, when trying to access to a simple test.php file (just has phpinfo() in it), I get the following list of errors: • IIS was not able to access the web.config file for the Web site or application. This can occur if the NTFS permissions are set incorrectly. • IIS was not able to process configuration for the Web site or application. • The authenticated user does not have permission to use this DLL. • The request is mapped to a managed handler but the .NET Extensibility Feature is not installed. The domain was created with dot net panel, but I don't think that has to do with this problem, unless maybe it uses a specific user? Maybe I need to add php thruough dot net panel? Any idea of what I'm doing wrong here?

• Copy Ubuntu distro with all settings from one computer to a different one

  - by theFisher86

  I'd like to copy my exact setup from my computer at work to my computer at home. I'm trying to figure out how to go about doing that. So far I've figured this much out. On the source computer run dpkg --get-selections > installed-software and backup the installed-software file Backup /etc/apt/sources.list Backup /usr/share/applications/ to save all my custom Quicklists Backup /etc/fstab to save all my network mounts Backup /usr/share/themes/ to save the customization I've done to my themes I'm also going to backup my entire HOME directory. Once I get to the destination computer I'm going to first do just a fresh install of 11.10 Then I'll copy over my HOME directory, /etc/apt/sources.list, /usr/share/appications, /etc/fstab and /usr/share/themes/ Then I'm going to run dpkg --set-selections < installed-software Followed by dselect That should install all of my apps for me. I'm wondering if there's a way/need to backup dconf and gconf settings from the source computer? I guess that's my ultimate question. I'd also like any notes on anything else that might need backed up as well before I undertake this project. I hope this post is legit, I figured other people would be interested in knowing this process and I don't see any other questions that seem to really document this on here. I'd also like to further this project and have each computer routinely backup all the necessary files so that both computer are basically identical at all times. That's stage 2 though...

• Is version history really sacred or is it better to rebase?

  - by dukeofgaming

  I've always agreed with Mercurial's mantra, however, now that Mercurial comes bundled with the rebase extension and it is a popular practice in git, I'm wondering if it could really be regarded as a "bad practice", or at least bad enough to avoid using. In any case, I'm aware of rebasing being dangerous after pushing. OTOH, I see the point of trying to package 5 commits in a single one to make it look niftier (specially at in a production branch), however, personally I think would be better to be able to see partial commits to a feature where some experimentation is done, even if it is not as nifty, but seeing something like "Tried to do it way X but it is not as optimal as Y after all, doing it Z taking Y as base" would IMHO have good value to those studying the codebase and follow the developers train of thought. My very opinionated (as in dumb, visceral, biased) point of view is that programmers like rebase to hide mistakes... and I don't think this is good for the project at all. So my question is: have you really found valuable to have such "organic commits" (i.e. untampered history) in practice?, or conversely, do you prefer to run into nifty well-packed commits and disregard the programmers' experimentation process?; whichever one you chose, why does that work for you? (having other team members to keep history, or alternatively, rebasing it).

• IIS 7 SSO stops working during high CPU load? [migrated]

  - by DanB

  On our IIS7 site (Windows 2008 Server), we have set up single sign-on (SSO). It seems to work fine most of the time, but when the CPU load becomes high, SSO authentication completely stops working. I did some research and tried this suggestion to increase the max number of worker processes in the default app pool, but the increase did not help. Some details: The site is a WordPress blog. The server has plenty of RAM (2 GB) and free disk space. SSO is achieved by putting a copy of the WordPress login page (wp-login.php) into a subfolder below the root that has anonymous authentication disabled, and then redirecting the browser to it. This was the recommendation of Microsoft given to our consultants. To increase CPU load for testing, I have three scripts hit the home page simultaneously, over and over. This drives CPU to 100%. When these scripts are running, SSO authentication simply doesn't happen. As soon as I stop the scripts, SSO works again. (I should mention that the SSO problem also happens when many users visit the site at once....) The WordPress database process (mysqld) is not stressed at all by the scripts. I would be happy to provide further diagnostics. Any help appreciated!

• Issue with broken disk on Solaris with raidctl - how to proceed

  - by weismat

  I have a SunFire T2000 server which has 2 mirrored disks pairs. The server required an exchange of the system battery. After swaping the battery first no disks were found. After booting from CD we managed to find the disks, but now one disk is broken and the raidctl reports a failed synchronisation. The boot process stops now when trying to mount the file systems. The power light of the broken drive is not even blinking. What is the best way to proceed now ? Fortunately I could live with loosing the data on the drive as it is backed up, but I would like to keep the rest of the data as it contains /etc and get the server booting again.

• How would you model an objects representing different phases of an entity life cycle?

  - by Ophir Yoktan

  I believe the scenario is common mostly in business workflows - for example: loan management the process starts with a loan application, then there's the loan offer, the 'live' loan, and maybe also finished loans. all these objects are related, and share many fields all these objects have also many fields that are unique for each entity the variety of objects maybe large, and the transformation between the may not be linear (for example: a single loan application may end up as several loans of different types) How would you model this? some options: an entity for each type, each containing the relevant fields (possibly grouping related fields as sub entities) - leads to duplication of data. an entity for each object, but instead of duplicating data, each object has a reference to it's predecessor (the loan doesn't contain the loaner details, but a reference to the loan application) - this causes coupling between the object structure, and the way it was created. if we change the loan application, it shouldn't effect the structure of the loan entity. one large entity, with fields for the whole life cycle - this can create 'mega objects' with many fields. it also doesn't work well when there's a one to many or many to many relation between the phases.
