  • How can MySQL be in GDAL's dependencies when it's already installed?

    - by Julien Fouilhé
    I'm trying to install GDAL on my CentOS 64 bits server to be able to make some GIS operations. I tried a simple: # yum install gdal First, the GDAL version is 1.4 (the last released one is 1.9) Then, I see in the dependencies list mysql. But I have mysql already installed, from another repository (remi), with a newer version than the one suggested by yum... Is it a problem of architecture (yum suggests i386)? I risked a yes, but still impossible to install it! Here's the error I have. Transaction Check Error: package mysql-5.5.28-1.el5.remi.x86_64 (which is newer than mysql-5.0.95-1.el5_7.1.i386) is already installed Then, I tried to install it from sources with last version available (1.9.2). I downloaded the GDAL tar.gz, extracted the files and installed it like following: # tar -xzf gdal-1.9.2.tar.gz # ./configure --with-static-proj4=/usr/local/lib --with-threads --with-libtiff=internal --with-geotiff=internal --with-jpeg=internal --with-gif=internal --with-png=internal --with-libz=internal # make # make install But during the make, I have some strange errors displaying, about RegisterOGRMySQL, that I can't understand: chmod a+x gdal-config /bin/sh /home/benjamin/gdal-1.9.2/libtool --mode=link g++ gdalinfo.lo /home/benjamin/gdal-1.9.2/libgdal.la -o gdalinfo libtool: link: g++ .libs/gdalinfo.o -o .libs/gdalinfo /home/benjamin/gdal-1.9.2/.libs/libgdal.so -L/usr/local/lib/lib -L/usr/kerberos/lib64 -lproj -lsqlite3 /usr/lib64/libexpat.so -lpthread -lrt -lcurl -ldl -lgssapi_krb5 -lkrb5 -lk5crypto -lcom_err -lidn -lssl -lcrypto -lz -Wl,-rpath -Wl,/usr/local/lib -Wl,-rpath -Wl,/usr/lib64 /home/benjamin/gdal-1.9.2/.libs/libgdal.so: undefined reference to `RegisterOGRMySQL' collect2: ld returned 1 exit status make[1]: *** [gdalinfo] Error 1 make[1]: Leaving directory `/home/benjamin/gdal-1.9.2/apps' make: *** [apps-target] Error 2 Has anyone a solution?

  • Multiple cable adapter setup not working - VGA to smartphone. All cables tested and work

    - by Christopher Rucinski
    Issue Pictured overhead projector setup does not work. #1 - #2 - #3 - Phone. All cables are tested and work! The issue is the HDMI connection between cable #2 and #3. With all other cables, the screen will automatically be displayed onto the projector screen. No extra work needed. With the pictured setup, the smartphone screen is not displayed onto the projector screen. What is the issue with the HDMI connection?? Background We recently had to do presentations at work (school), but the administration only provided VGA means of hooking up to it. Mostly likely reason probably dealt with cost. Anyways, there are several teachers that have brand new Samsung Series 9 ultrabooks (or similar). You know, the ones without VGA support. So I bought an adapter for those ultrabooks. Cable #5 in the picture below. However, both my coworker and I have been wanting to just display our phone screens on the projector. This I knew would require some extra work. What I have VGA cable to projector (cables go through the wall) For laptops HDMI to VGA cable For laptops MHL adapter For 11-pin microUSB phones microHDMI to VGA cable For ultrabooks 11-pin to 5-pin microUSB adapter For older 5-pin microUSB phones) Equipment Projectors 1 projector with VGA and HDMI input (issue is coworkers forget to switch sources) 1 projector with VGA only input Laptops 2 new Samsung ultrabooks w/o VGA or HDMI support 1 ultrabook with VGA and HDMI support several other laptops with at least VGA support 1 tablet with 11-pin microUSB at least 1 new phone with 11-pin microUSB at least 1 old phone with 5-pin microUSB Tested VGA cable (#1) to laptop Good VGA cable (#1) to HDMI adapter (#2) to laptop Good VGA cable (#1) to microHDMI adapter (#5) to laptop Good Projector to HDMI cable (not shown) to MHL adapter (#3) to Galaxy Note 3 smartphone Good VGA cable (#1) to HDMI adapter (#2) to MHL adapter (#3) to Galaxy Note 3 smartphone Does not work!!

  • How to Print or Save a Directory Listing to a File

    - by Lori Kaufman
    Printing a directory listing is something you may not do often, but when you need to print a listing of a directory with a lot of files in it, you would rather not manually type the filenames. You may want to print a directory listing of your videos, music, ebooks, or other media. Or, someone at work may ask you for a list of test case files you have created for the software you’re developing, or a list of chapter files for the user guide, etc. If the list of files is small, writing it down or manually typing it out is not a problem. However, if you have a lot of files, automatically creating a directory listing would get the task done quickly and easily. This article shows you how to write a directory listing to a file using the command line and how to use a free tool to print or save a directory listing in Windows Explorer.

  • Big label generator

    - by jamiet
    Sometimes I write blog posts mainly so that I can find stuff when I need it later. This is such a blog post. Of late I have been writing lots of deployment scripts and I am fan of putting big labels into deployment scripts (which, these days, reside in SSDT) so one can easily see what’s going on as they execute. Here’s such an example from my current project: which results in this being displayed when the script is run: In case you care….PM_EDW is the name of one of our databases. I’m almost embarrassed to admit that I spent about half an hour crafting that and a few others for my current project because a colleague has just alerted me to a website that would have done it for me, and given me lots of options for how to present it too: http://www.patorjk.com/software/taag/#p=testall&f=Banner3&t=PM__EDW Very useful indeed. Nice one! And yes, I’m sure there are a myriad of sites that do the same thing - I’m a latecomer, ok? @Jamiet

  • What are the legal risks if any of using a GPL'ed Web Application Framework/CMS?

    - by Seth Spearman
    Tried to ask this on SO but was referred here... Am I correct in saying that using a GPL'ed web application framework such as Composite C1 would NOT obligate a company to share the source code we write against said framework? That is the purpose of the AGPL, am I correct? Does this also apply to Javascript frameworks like KendoUI? The GPL would require any changes that we make to the framework be made available to others if we were to offer it for download. In other words, merely loading a web sites content into my browser is not "conveying" or "distributing" that software. I have been arguing that we should avoid GPL web frameworks and now after researching I am pretty sure I am wrong but wanted to get other opinions? Seth

  • App Store: Profitability for Game Developers

    - by Bunkai.Satori
    Recent days, I've been spending significant time in discovering chances of profitability of AppStore for developers. I have found many articles. Some of them are highly optimistic, while other are extremely skeptical. This article is extremely skeptical. It even claims to have backed its conclusions by objective sales numbers. This is another pesimistic article saying that games developed by single individuals get 20 downloads a day. Can I kindly ask to clarify from business viewpoint whether average developers publishing games and software on AppStore can cover their living expenses, even, whether they can become profitable? Is it achievable to generate revenues of 50.000 USD yearly on AppStore for a single developer? I would like to stay as realistic as possible. Despite the question might look subjective, a good business man will be able to esitmate chances for profitability and prosperity within AppStore.

  • What Contents in a Young Programmer's Personal Website

    - by DotNetStudent
    I recently stumbled upon this question in which the contents a professional programmer's website should have were discussed and I agree with most of the answers there. However, I am by no means a professional programmer (just came out from university) and so I am a bit lost in what concerns the contents I should provide in the personal website I am designing for myself now. I do have a pretty nice job at a fast-growing software company but I would really like to present myself to the outside world in a nice but humble manner since my curriculum is by no means a long one. Any ideas?

  • HTG Explains: What Does “Bricking” a Device Mean?

    - by Chris Hoffman
    When someone breaks a device and turns it into an expensive brick, people say they “bricked” it. We’ll cover exactly what causes bricking and why, how you can avoid it, and what to do if you have a bricked device. Bear in mind that many people use the term “bricking” incorrectly and refer to a device that isn’t working properly as “bricked.” if you can easily recover the device through a software process, it’s technically not “bricked.” Image Credit: Esparta Palma on Flickr HTG Explains: What is the Windows Page File and Should You Disable It?

  • Tips/Process for web-development using Django in a small team

    - by Mridang Agarwalla
    We're developing a web app uing Django and we're a small team of 3-4 programmers — some doing the UI stuff and some doing the Backend stuff. I'd love some tips and suggestions from the people here. This is out current setup: We're using Git as as our SCM tool and following this branching model. We're following the PEP8 for your style guide. Agile is our software development methodology and we're using Jira for that. We're using the Confluence plugin for Jira for documentation and I'm going to be writing a script that also dumps the PyDocs into Confluence. We're using virtualenv for sandboxing We're using zc.buildout for building This is whatever I can think of off the top of my head. Any other suggestions/tips would be welcome. I feel that we have a pretty good set up but I'm also confident that we could do more. Thanks.

  • Nothing seems to be syncing with Ubuntu One

    - by Anthony Papillion
    So earlier tonight I set up Ubuntu One on a fresh install of Ubuntu 10.10. In my "Ubuntu One" directory, I created symbolic links to /Documents /Pictures and /Music. Right now, there is VERY little in those directories but what IS there isn't syncing at all. When I go to the Ubuntu One web interface, it tells me I'm using 0.00% of my storage space. When I try to view the files in the web interface, I am told 'Something has gone wrong' and I don't see anything. Can anyone help? Even my Tomboy notes aren't syncing! And yes, I am connected and the software says 'Synchronisation Complete' Thanks, Anthony

  • Can I have a single solid state drive and a RAID array on the same machine?

    - by jaminto
    Hi- To summarize, i'm looking to use a single solid state drive as my primary drive, and two conventional sata drives in a RAID 1 configuration for data. I am trying to install 64-bit Windows 7 onto this configuration. Is this possible? Here are the details: I built a desktop that has been running 64-bit Vista on two 500Gb in a RAID 1 array for a few years. I just purchased an Intel X25-M 80Gb Sata Solid-State Drive, and was planning on using this a my primary drive, and keeping the RAID 1 array as my data drive. I added the SSD drive and in the RAID setup, configured it as a RAID 0 array of only one disk. Then, I tried to do a clean install of windows 7 64-bit, but got stuck in the "Missing driver for CD/DVD drive" black hole of selecting driver files and Windows telling me that i don't have the appropriate driver for my hardware. The missing hardware is NOT a CD/DVD drive, since i'm installing off of my only CD/DVD drive. Plus at one point i was able to point it at a driver for my raid controller, and then my hard drives magically showed up as browsable sources for finding drivers for some other unnamed device that setup couldn't recognize. After a few hours of trying drivers (this was a very slow process) i decided to reboot and look at the BIOS settings. I'm using an ASUS M2A-VM motherboard which has an ATI SB600 RAID controller on board. I switched the "On board SATA Type" setting from "SATA" to "AHCI" thinking that since AHCI is an Intel thing, this would help. Unfortunately, this abandoned my RAID configuration, and my previously mirrored drives are showing up as separate drives when i boot into my current windows installation. Am i trying to do the impossible here? Should i just buy a separate SATA/RAID PCI card and plug the SSD into that? Any help would be greatly appreciated.

Agile development frequently revisits each part of the source code, but every change requires a re-test of the product. While the skills of the manual tester are vital, purely manual testing can't keep up. Visual Studio 2012 provides many features that remove roadblocks in the testing and debugging process and also help speed up and automate re-testing."

  • Bare minimum on the Joel Test

    - by Fung
    From the Joel Test, of the 12, which do you think are the absolute must-haves to at least have a decently running software department/company? I realise there is no absolutely right answer. I'm just trying to get opinions of others out there. My own organization only manages a measly 5 of 12. If you check listings on Careers 2.0, most companies don't score a full 12 either but I'm sure they're doing fine. Does SO publish the stats for those anywhere? Or has anyone tried scrapping the results? Would be interesting to know which are practised the most. And whether because they are easier to implement or whether they actually have the most impact. Thanks.

  • Find only physical network adapters with WMI Win32_NetworkAdapter class

    - by Mladen Prajdic
    WMI is Windows Management Instrumentation infrastructure for managing data and machines. We can access it by using WQL (WMI querying language or SQL for WMI). One thing to remember from the WQL link is that it doesn't support ORDER BY. This means that when you do SELECT * FROM wmiObject, the returned order of the objects is not guaranteed. It can return adapters in different order based on logged-in user, permissions of that user, etc… This is not documented anywhere that I've looked and is derived just from my observations. To get network adapters we have to query the Win32_NetworkAdapter class. This returns us all network adapters that windows detect, real and virtual ones, however it only supplies IPv4 data. I've tried various methods of combining properties that are common on all systems since Windows XP. The first thing to do to remove all virtual adapters (like tunneling, WAN miniports, etc…) created by Microsoft. We do this by adding WHERE Manufacturer!='Microsoft' to our WMI query. This greatly narrows the number of adapters we have to work with. Just on my machine it went from 20 adapters to 5. What was left were one real physical Realtek LAN adapter, 2 virtual adapters installed by VMware and 2 virtual adapters installed by VirtualBox. If you read the Win32_NetworkAdapter help page you'd notice that there's an AdapterType that enumerates various adapter types like LAN or Wireless and AdapterTypeID that gives you the same information as AdapterType only in integer form. The dirty little secret is that these 2 properties don't work. They are both hardcoded, AdapterTypeID to "0" and AdapterType to "Ethernet 802.3". The only exceptions I've seen so far are adapters that have no values at all for the two properties, "RAS Async Adapter" that has values of AdapterType = "Wide Area Network" and AdapterTypeID = "3" and various tunneling adapters that have values of AdapterType = "Tunnel" and AdapterTypeID = "15". In the help docs there isn't even a value for 15. So this property was of no help. Next property to give hope is NetConnectionId. This is the name of the network connection as it appears in the Control Panel -> Network Connections. Problem is this value is also localized into various languages and can have different names for different connection. So both of these properties don't help and we haven't even started talking about eliminating virtual adapters. Same as the previous one this property was also of no help. Next two properties I checked were ConfigManagerErrorCode and NetConnectionStatus in hopes of finding disabled and disconnected adapters. If an adapter is enabled but disconnected the ConfigManagerErrorCode = 0 with different NetConnectionStatus. If the adapter is disabled it reports ConfigManagerErrorCode = 22. This looked like a win by using (ConfigManagerErrorCode=0 or ConfigManagerErrorCode=22) in our condition. This way we get enabled (connected and disconnected adapters). Problem with all of the above properties is that none of them filter out the virtual adapters installed by virtualization software like VMware and VirtualBox. The last property to give hope is PNPDeviceID. There's an interesting observation about physical and virtual adapters with this property. Every virtual adapter PNPDeviceID starts with "ROOT\". Even VMware and VirtualBox ones. There were some really, really old physical adapters that had PNPDeviceID starting with "ROOT\" but those were in pre win XP era AFAIK. Since my minimum system to check was Windows XP SP2 I didn't have to worry about those. The only virtual adapter I've seen to not have PNPDeviceID start with "ROOT\" is the RAS Async Adapter for Wide Area Network. But because it is made by Microsoft we've eliminated it with the first condition for the manufacturer. Using the PNPDeviceID has so far proven to be really effective and I've tested it on over 20 different computers of various configurations from Windows XP laptops with wireless and bluetooth cards to virtualized Windows 2008 R2 servers. So far it always worked as expected. I will appreciate you letting me know if you find a configuration where it doesn't work. Let's see some C# code how to do this: ManagementObjectSearcher mos = null;// WHERE Manufacturer!='Microsoft' removes all of the // Microsoft provided virtual adapters like tunneling, miniports, and Wide Area Network adapters.mos = new ManagementObjectSearcher(@"SELECT * FROM Win32_NetworkAdapter WHERE Manufacturer != 'Microsoft'");// Trying the ConfigManagerErrorCode and NetConnectionStatus variations // proved to still not be enough and it returns adapters installed by // the virtualization software like VMWare and VirtualBox// ConfigManagerErrorCode = 0 -> Device is working properly. This covers enabled and/or disconnected devices// ConfigManagerErrorCode = 22 AND NetConnectionStatus = 0 -> Device is disabled and Disconnected. // Some virtual devices report ConfigManagerErrorCode = 22 (disabled) and some other NetConnectionStatus than 0mos = new ManagementObjectSearcher(@"SELECT * FROM Win32_NetworkAdapter WHERE Manufacturer != 'Microsoft' AND (ConfigManagerErrorCode = 0 OR (ConfigManagerErrorCode = 22 AND NetConnectionStatus = 0))");// Final solution with filtering on the Manufacturer and PNPDeviceID not starting with "ROOT\"// Physical devices have PNPDeviceID starting with "PCI\" or something else besides "ROOT\"mos = new ManagementObjectSearcher(@"SELECT * FROM Win32_NetworkAdapter WHERE Manufacturer != 'Microsoft' AND NOT PNPDeviceID LIKE 'ROOT\\%'");// Get the physical adapters and sort them by their index. // This is needed because they're not sorted by defaultIList<ManagementObject> managementObjectList = mos.Get() .Cast<ManagementObject>() .OrderBy(p => Convert.ToUInt32(p.Properties["Index"].Value)) .ToList();// Let's just show all the properties for all physical adapters.foreach (ManagementObject mo in managementObjectList){ foreach (PropertyData pd in mo.Properties) Console.WriteLine(pd.Name + ": " + (pd.Value ?? "N/A"));}   That's it. Hope this helps you in some way.

  • GPL: does one line of GPLed code make program a "derived work"

    - by SigTerm
    I've recently run into some argument with a person that claims to be a lawyer (I have my suspicions about this not being completely true, though). As far as I know, copying even one line of code from GPLed program into proprietary body of code requires you to release the whole thing under GPL, if you ever decide to publish the software and make it available to the public. The person in question claims that it is "absurd" (I know it is, but AFAIK that's how GPL works), it is "redefining the copyright", "GPL has no power to do that", and claiming that "one line of GPLed code makes you release the whole thing under GPL" is absurd. That contradicts the GPL FAQ. Can somebody clarify the situation? Am I right in assumption that copying even smallest subroutine from GPL program into your code automatically makes your program a "derived work" which means you are obliged to release it under GPL license if you publish it?

  • How do I change which audio jacks are used for input and output?

    - by yamaha1996
    I'm using a Realtek HD audio card built-in my motherboard. The Windows driver comes with a control panel that allows me to select which back panel jacks are used for what. So for example I can make both the blue jack and green jack for output and only the red one for mic-in. (Whereas by default, the blue jack is for line in, which I never need.) How can I do the same under Linux? If possible, please don't suggest something that involves PulseAudio or JACK; I'd like to do it the plain way, e.g. by editing ALSA configuration files, if possible. The way I understand it, my problem should have nothing to do with software servers redirecting streams, just instructing the driver to treat this jack as so and so because it's hardware supported. Thank you very much!

  • GlassFish Clustering with DCOM on Windows

    - by ByronNevins
    DCOM - Distributed COM, a Microsoft protocol for communicating with Windows machines. Why use DCOM? In GlassFish 3.1 SSH is used as the standard way to run commands on remote nodes for clustering.  It is very difficult for users to get SSH configured properly on Windows.  SSH does not come with Windows so we have to depend on third party tools.  And then the user is forced to install and configure these tools -- which can be tricky. DCOM is available on all supported platforms.  It is built-in to Windows. The idea is to use DCOM to communicate with remote Windows nodes.  This has the huge advantage that the user has to do minimal, if any, configuration on the Windows nodes. Implementation HighlightsTwo open Source Libraries have been added to GlassFish: Jcifs – a SAMBA implementation in Java J-interop – A Java implementation for making DCOM calls to remote Windows computers.   Note that any supported platform can use DCOM to work with Windows nodes -- not just Windows.E.g. you can have a Linux DAS work with Windows remote instances.All existing SSH commands now have a corresponding DCOM command – except for setup-ssh which isn’t needed for DCOM.  validate-dcom is an all new command. New DCOM Commands create-node-dcom delete-node-dcom install-node-dcom list-nodes-dcom ping-node-dcom uninstall-node-dcom update-node-dcom validate-dcom setup-local-dcom (This is only available via Update Center for GlassFish 3.1.2) These commands are in-place in the trunk (4.0).  And in the branch (3.1.2) Windows Configuration Challenges There are an infinite number of possible configurations of Windows if you look at it as a combination of main release, service-pack, special drivers, software, configuration etc.  Later versions of Windows err on the side of tightening security be default.  This means that the Windows host may need to have configuration changes made.These configuration changes mostly need to be made by the user.  setup-local-dcom will assist you in making required changes to the Windows Registry.  See the reference blogs for details. The validate-dcom Command validate-dcom is a crucial command.  It should be run before any other commands.  If it does not run successfully then there is no point in running other commands.The validate-dcom command must be used from a DAS machine to test a different Windows machine.  If  validate-dcom runs successfully you can be confident that all the DCOM commands will work.  Conversely, the opposite is also true:  If validate-dcom fails, then no DCOM commands will work. What validate-dcom does Verify that the remote host is not the local machine. Resolves the remote host name Checks that the remote DCOM port is being listened on (135, 139) Checks that the remote host’s File Sharing is enabled (port 445) It copies a file (a script) to the remote host to verify that SAMBA is working and authorization is correct It runs a script that it copied on-the-fly to the remote host. Tips and Tricks The bread and butter commands that use DCOM are existing commands like create-instance, start-instance etc.   All of the commands that have dcom in their name are for dealing with the actual nodes. The way the software works is to call asadmin.bat on the remote machine and run a command.  This means that you can track these commands easily on the remote machine with the usual tools.  E.g. using AS_LOGFILE, looking at log files, etc.  It’s easy to attach a debugger to the remote asadmin process, “just in time”, if necessary. How to debug the remote commands:Edit the asadmin.bat file that is in the glassfish/bin folder.  Use glassfish/lib/nadmin.bat in GlassFish 4.0+Add these options to the java call:-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=1234  Now if you run, say start-instance on DAS, you can attach your debugger, at your leisure, to the remote machines port 1234.  It will be running start-local-instance and patiently waiting for you to attach.

  • How do I install pepper-flash on Chromium?

    - by user209900
    I have Chromium web browser on my Lubuntu 13.04 (pre-installed). I use LX Terminal (pre-installed) to write commands. I am trying to download flash player on Chromium using instructions on this site : sudo add-apt-repository ppa:skunk/pepper-flash After typing in my password, this worked. Now sudo apt-get update I didn't need to type in my password, as I continued on the same terminal, but got W:/ and E:/ fetch file errors sudo apt-get install pepflashplugin-installer I continued on the same terminal despite the fetch file errors... and they said pepflashplugin-installer could not be found. Is the last error because of fetch file errors, or because I need to download pepflash-plugin-installer somewhere? Or is it because of something else? I cannot download the Chrome browser, and not looking to use flash player on my Firefox web browser (installed using lubuntu software centre).

  • Clever DIY Display Showcases Game Consoles While Concealing Cables

    - by Jason Fitzpatrick
    How do you display all your vintage game consoles while keeping them in a clutter free and ready-to-play state? This wall-mounted display does a great job showing off the retro gear while keeping everything tidy. Courteys of German tinker and gamer Holger, the design of the display is deceptively simple. The wall mount is a basic 2×4 frame wrapped in black roofing batten (similar to the lightweight weed-fabric used in gardens). Screw-in mounts for the LACK shelves are positioned every foot or so going up the frame and a small slit in the fabric allows for hidden routing of the cables. While it looks like the consoles are simply on display, they’re actually all hooked up and ready to play. For more photos of the build, hit up the link below.
