  • Compiling Ruby on Mac OS X Snow Leopard

    - by gryzzly
    Hi, I am trying to follow this tutorial, on the subject of compiling ruby and rubygems on Snow Leopard: http://hivelogic.com/articles/compiling-ruby-rubygems-and-rails-on-snow-leopard I have added this to my ~/.profile: export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH" But if I write: echo $PATH I get: /opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin:/usr/X11/bin But in tutorial it says: You should see /usr/local/bin at the beginning of the line returned by the system. I have installed macports sometime ago and plenty of other software, perhaps it has changed the path. Anyway, I have tried to proceed with the installation, so I have built ruby, I did: ./configure --enable-shared --enable-pthread CFLAGS=-D_XOPEN_SOURCE=1 make sudo make install cd .. But when I do which ruby I get: /usr/bin/ruby And according to the tutorial that's wrong. Also if I do ruby -v I get the older version of ruby that was preinstalled on Snow Leopard and not the one I've compiled. Thanks.

  • How can I get my License Key from a boot CD?

    - by dubRun
    We recently acquired a server that's been in use for a while, but no associated software, logins, etc. We attempted to blank the administrator account password, but that didn't work. We also tried some deeper edits on the password, but no avail there either. Now what I'm looking to do is to re-install windows using the existing registry key on the server now. I've read that you can access the product key in the registry, and using the password tool (a linux boot cd) we are able to view the registry. When I tried this, I got the ProductId (Which version of windows), not the registry key. The OS I'm attempting to read from in Windows Server 2003 R2.

  • VMWare Host needing ESXi 5.0 - Running on a 2008 R2 Host?

    - by Great Big Al
    I have a VMWare image supplied by my Phone System provider which manages a contact management interface, they tell me that VMWare EsXi5.0 is the highest supported host. I'm used to MS HyperV and have no VMWare experiance. At present I have this guest running on a simple desktop PC running ESXi5.0.0, I'd idealy like to run this guest (it's Windows 7 with their software already installed and configured) on a Windows 2008R2 server I have available, as I said, I'm used to HyperV and I can't easily identify if there is a version of VMWare that supports ESXi5.0 guests that will run on a Windows 2008 R2 server host. Is there such a product, what's it called, and with one guest can I run it without purchasing a license? Thanks

  • Seeking solution for printing-reporting .NET

    - by Parhs
    I am developing an application that prints in separate threads in extreme cases about 20-25 pages per minute to various thermal printers. Currently templates for these are XAML xps documents. All printers have graphics drivers that support EMF/GDI printing. So GDI-EMF is done by operating system resulting in slower performance. Sending raw text for printing is another good solution but doesnt work always , because some clients have old chinese thermal printer that nobody support thus impossible to change codepage / emulation. So it doesnt work always. Also most computers running my software are low end ATOM CPU. So I am thinking to return to GDI, EMF printing and have both Text-Only reports and EMF reports. Another reason i want EMF is because here receipts are signed by Electronic Fiscal Memory device.Most of these dont do good job extracting text from XPS as they dont follow the standard but how windows convert GDI to XPS.Even with text-only mode some of them dont support all character encodings and are impossible to send paper cut command after the sign. I know that using a reporting engine would solve rendering problem but I dont want to buy one. All I want is to be able to show tabular data and insert an image and replaced text.I know there is StringTemplate that could do the generation of template but the problem is i should parse somehow the template and render it using GDI commands. Is there any other solution/approach for this ? Or is there anything ready ?

  • How to get Atheros ar242x wireless adapter working under Debian Linux?

    - by Mark
    Does anybody know how to get the Atheros ar242x wireless adapter working under Debian Linux (5.0.2 and/or 5.0.3)? My Debian live CDs and install CDs both don't like this card at all. Curisouly, it seems to work on other, Debian-based, Linuxes. Is this a free/non-free Driver issue? I know Debian gets mardy about that. Although for what it's worth, the Live CD doesn't seem to detect my wired LAN connection either... Specifically this is on a Samsung R610 laptop (some version of which seem to have an intel wireless adapter - this one definitely doesn't!) I've tried all sorts of things but obviously on a live CD installing software is limited. I've also tinkerering with network config files and kernel modules etc but to no avail.

  • Free MPEG cutting/cropping/editing tool

    - by Stijn Sanders
    I'm looking for a free tool to cut MPEG's that are created by recording from a USB cable receiver. There are a number of applications that do this, and some are free, but most of them take the video and audio decoded and pass them into a codec again to write the final output. I already have the MPEG's encoded the way I like, so what I need is a tool that can strip the beginning and the ending of the recording before and optionally commercial breaks, by rearranging the data within the file, not re-encoding it. Now I'm using some old software that came with the cable-receiver, but this actually re-encodes the video when exporting. I've tried VirtualDub but had major trouble getting the audio and video streams to stay in sync (and this was also re-encoding)... I found this which comes pretty close, but doesn't allow much accuracy in selecting cut positions.

  • Why would accessing photos over a network be a problem for Digikam?

    - by Shedeki
    Digikam has always worked nicely for me. I recently setup a Synology DiskStation (DS212+) and moved all my pictures to it, keeping them in an encrypted folder. I mount that folder using cifs, as some bug prevents eCryptfs and NFS from working together. This has led Digikam to being incredibly slow. Startup takes a very long time (several minutes for 41779 items, 123.8GB) but worse is how long it takes Digikam to write files. I like using Digikams import feature to copy new images from my camera to the hard drive because it checks for duplicates as well as creating a clear folder structure according to the dates the images were taken. Since I moved to using the network drive Digikam takes about 5 to 10 times as long to import photos than it did before. Saving modified or converted images takes equally long. What I am looking for is a way to help Digikam speed things up or an alternative piece of software (I have never liked Digikam being so very much KDEish…). There are just so many features that only Digikam seems to combine, e.g.: Batch processing. Respects existing folder structure. Does not mess up files for other applications. *.NEF support. Caches thumbnails in a clean way.

Documents must reflect current practice and they must be accurate. The most effective way to ensure this is through the regular audit of documents. In the Tutor environment, a Document Owner must audit each of his/her documents once every 6 to 12 months to verify that the document reflects actual practice. If it does not, the document is updated or employees are retrained (depending on the nature of the discrepancy). If a document update is required, the Tutor system enables the owner to modify and redistribute the document within one work day. This is possible because: Documents contain a minimum of detail, thereby reducing the edits. Document format and structure are simple, so changes are easy to identify The Tutor Author software tool enables the Document Owner or the Document Administrator to update the file quickly. The Document Administrator verifies the document format and integration, publishes the document, and distributes it to all affected employees, thereby freeing the Document Owner of the more tedious tasks.

  • Citrix Access Gateway not redirecting to login URL

    - by Dave
    We have an older setup for XenApp - users log in through Citrix Secure Gateway running on a windows box. (We hope to start using a NetScaler soon.) Earlier today, connections to https://citrix.company.com/ starting throwing up a 503 error page, instead of redirecting to https://citrix.company.com/Citrix/XenApp/ If you go directly to the /Citrix/Xenapp/ URL, the user is properly directed to the login page, and can launch apps. We've restarted the service, and rebooted the server. We haven't yet tried uninstalling and reinstalling the software. Before we do this, I'm looking for ideas as to how we can get the redirect working again without a fairly major outage window. To make things more interesting, many of our users have Citrix Receiver installed, also pointed at https://citrix.company.com/. Receiver makes itself the default launcher for ICA files, and gives a connection error when it tries to load apps - probably because of the same non-functional rediect?

  • Isolate user from the rest of the system..?

    - by Shiki
    There is a non-techsavvy user, who doesn't want to learn, and can only use Windows XP or 7. The problem is, that the computer is shared which she would like to use, and the computer stores sensitive, important data. Since she clicks on everything, it's quite a russian roulette. How could I isolate her account from the rest of the system? Like having a profile on the computer (it runs Windows 7 now) which would have the files and other stuff sandboxed? I was thinking of having a dual boot system, but that could compromise the files too, or the boot sector (talking about Windows). Linux is not a way, hence ... see the first line. Is there such a software that can set up a sandboxed environment?

  • Limit disk I/O one program creates?

    - by Posipiet
    Hardware: one virtualization server. Dual Nehalem, 24GB RAM, 2 TB mirrored HD. Software: Debian, KVM, virt-manager on the server with several virtual machines that use Linux too. 2 TB Disk is a big LVM, each VM gets a logical volume and makes its own partitions in that. Problem: One of the programs that runs on one of the VMs creates huge disk load. This never was an issue, because the program never ran on such a powerful hardware. Now the CPUs are fast, and lots of I/O is the result. We cant do much against that at the moment, because the tool is a black box. On the other hand, the speedy computation is welcome. The program creates about 5 GB of temp files which get overwritten during the next iteration. Question: How can we limit the disk I/O for the process?

  • Friday Tips #5

    - by Chris Kawalek
    Happy Friday, everyone! Following up on yesterday's post about Oracle VM VirtualBox being selected as the best virtualization solution for 2012 by the readers of Linux Journal, our Friday tip is about that very cool piece of software: Question: How do I move a VM from one machine to another with Oracle VM VirtualBox? Answer by Andy Hall, Product Management Director, Oracle Desktop Virtualization: There are a number of ways to do this, with pros and cons for each. The most reliable approach is to Export and Import virtual machines: From the VirtualBox manager, simply use the File…Export appliance menu and follow the wizard's lead. Move the resulting file(s) to the destination machine; and Import the VM into VirtualBox. This method will take longer and use more disk space than other methods because the configuration files and virtual hard drives are converted into an industry standard format (.ova or .ovf). But an advantage of this approach is that the creator of the virtual appliance can add a license which the importer will see and click-to-accept at import time. This is especially useful for ISVs looking to deliver pre-built, configured and tested appliances to their customers and prospects. Thanks Andy! Remember, if you have a question for us, use Twitter hashtag #AskOracleVirtualization. We'll see you next week! -Chris

  • What is your strategy for converting RC builds into retail?

    - by Matthew PK
    We're trying to implement a strategy for how we transition our builds from RC to released retail code. When we label a build as a release candidate, we send it to QA for regression. If they approve it, that RC then becomes our released retail code. I liked the idea of "obvious" labeling of versions so that a user knows whether they have a beta or an RC or retail code... where you would have some obvious watermark in non-retail code (think Windows 7 where the RC or non-genuine builds watermark in the bottom right). ... but it seemed strange to us to manipulate the project (to remove the watermark) once it passed regression. If QA certified version a.b.c.d then our retail code should be that same version, not a.b.c.d+1 what strategies have you employed to clearly label non-release software versions without incrementing your build to disable the watermarks in your retail code? One idea I've considered is writing your build to look for a signed file in the installer archive... non-release code wouldn't include this file and so the app would know to display a watermark. But even this seems like QA is then working with non-release code. Ideas?

  • How do I replicate autohotkey hotstrings in Chrome OS

    - by IThink
    Google gave me a Cr-48 about a month ago. I like it. Its simple and powerful. The temptation to fuss and muss has been removed. However, one of the things I miss a lot is hotstrings that I set up in autohotkey. So for instance typing "asap" will autoexpand to "as soon as possible" no matter what software I am in. I cannot do that in Chrome OS. Google Docs has something under toolspreferencesautomatic substitution but that is only specific to Google Docs. I want to have hotstrings everywhere.

  • NetBeans Hangs on New Project Creation

    - by Jason
    When creating a New Project in NetBeans, it hangs on the creation screen; Screenshot I'm running Netbeans 7.0.1 on Xubuntu 13.04. Java -version prints: java version "1.7.0_25" OpenJDK Runtime Environment (IcedTea 2.3.10) (7u25-2.3.10-1ubuntu0.13.04.2) OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode) /usr/lib/jvm/ contains the following folders; java-1.5.0-gcj-4.7-amd64 java-6-openjdk-amd64 java-7-openjdk-common java-1.6.0-openjdk-amd64 java-6-openjdk-common java-1.7.0-openjdk-amd64 java-7-openjdk-amd64 I tried editing /usr/share/netbeans/7.0.1/etc/netbeans.conf with the following (as was suggested in another post); netbeans_jdkhome="/usr/lib/jvm/java-7-openjdk-amd64/jre/" But that didn't work. Instead, NetBeans then presented an error on the loading splash when it reached "Turning on Modules..." claiming the JDK was missing. Both NetBeans and the OpenJDK Java 7/6 Runtimes were installed through the Ubuntu Software Centre. I've also tried uninstalling and reinstalling both Java and NetBeans. Any help would be greatly appreciated, thanks!

  • Import PDF in Inkscape without per character spacing

    - by Morinar
    I have a PDF form I imported into Inkscape. It did a pretty great job of created an SVG from it, however it appears to have given per character x coordinates to each tspan in every text block. I'm not sure, but I think this is making the FOP render that our software does ridiculously slow (running it through other renderers like IBEX it seems fine). I'd like to import it but have it not do per character positions. I can't seem to find any sort of PDF importing options at all. Does such a thing exist? Or is there perhaps some other, better freeware application I could use to generate the SVG from the PDF then use Inkscape to do adjustments from there? Thanks in advance.

  • How to achieve reliable Gigabit Ethernet Link with my Acer Aspire Revo R3610?

    - by The Operator
    I want to stream HD movies over my wired Gigabit LAN from my PC to my Acer Aspire Revo R3610. It's connected with a 3ft Cat5e patch cable to my Netgear GS605v2 Switch. The PC acting as File Server is connected at 1Gbps to the Switch. Network driver options are set to defaults, including automatic speed/duplex negotiation on both machines. The Revo will not connect to my Network Switch at 1Gbps - the OS reports that it reverts to 100Mbps either shortly after connection or immediately upon connection. Through a process of elimination (trying different drivers, patch cables, ports on the switch, and other 1Gbps-capable devices connected to the Network switch which successfully achieve 1Gbps links and performance) I have drawn the conclusion there is either a Hardware or Software (Driver) issue with the Revo itself. I have performed tests using Windows 7 and Ubuntu 9.10. Can anyone offer insight on Gigabit Ethernet with the Revo?

  • Making files generally available on Linux system (when security is relatively unimportant)?

    - by Ole Thomsen Buus
    Hi, I am using Ubuntu 9.10 on a stationary PC. I have a secondary 1 TB harddrive with a single big logical partition (currently formatted as ext4). It is mounted as /usr3 with options user, exec in /etc/fstab. I am doing highspeed imaging experiments. Well, only 260fps, but that still creates many individual files since each frames is saved as one png-file. The stationary is not used by anyone other than me which is why the default security model posed by ubuntu is not necessary. What is the best way to make the entire contents of /usr3 generally available on all systems. In case I need to move the harddrive to another Ubuntu 9.x or 10.x machine? When grabbing image with the firewire camera I use a selfmade grabbing software-utility (console based) in sudo-mode. This creates all files with root as owner and group. I am logged in as user otb and usually I do the following when having to make files generally available to otb: sudo chown otb -R * sudo chgrp otb -R * sudo chmod a=rwx -R * This takes some time since the disk now contains individual ~200000 files. After this, how would linux behave if I moved the harddrive to another system where the user otb is also available? Would the files still be accessible without sudo use?

  • Infrastructure to effectively set up experiements and learn from them

    - by David
    Open-org.com is in the early stages of creating our first product, a place on the web, where one can ask lawyers questions at a fraction of their normal costs. An early stage front page can be found here. I got inspired by this video, which is recommended by Jeff Atwood, which talks about getting feedback faster, which is the reason for this question. The problem Needless to say, we want our conversion rates to be as high as possible. Therefore, we want to be able to rapidly set up a new experiment where we change something on the site (like moving an image slightly, rewriting a sentence etc.). We then want to present the modified page to a random subset of the users. After that we will compare the conversion rates of the experiment with another version. I could very well imagine that we want to run 10-100 experiments simultaneously and it would be nice to have features, where experiments that obviously have worse results will be ended before schedule. My question Does infrastructure to support the whole process exist? A short description of our infrastructure... We use EC2 and PHP and have a script to automatically start up new instances with all needed software. Still, starting up a new server for every experiment, seems like a bit of overkill, so I am wondering what other options exist. Btw. If you feel like working for Open-org.com, you can pick a task, and start working, or suggest a new task. All profits are given out to the contributors.

  • Why is Google Home page changing spontaneously

    - by Bob
    Periodically, my Google Chrome home page (which I have originally set myself) changes spontaneously on opening the browser to display, instead, the page showing the rectangular small images of webpages I have visited before. In addition the bookmarks bar and my homepage icon has disappeared. I am also not directed to any other website location as might occur if a virus or malware were involved. I can correct all of these changes back to my original settings the way I prefer (and nothing prevents my resetting it) and can continue to browse with no difficulty but this changed situation has happened several times in the past month. I had assumed that this was an idiosyncrasy of how Chrome (mis)behaves but worry whether virus or malware might be involved. I have monitoring by antiviral and antimalware software and run periodic complete scans and occasionally these find Trojans and other malware which are removed but this browser behavior seems to recur I would like to prevent the surprises Thank you.

  • Suggestion for boot manager in external hard disk

    - by Korrupzion
    Hi, I just bought an 1TB External Hard drive with eSATA, USB, FW400/800 (LaCie if you are interested). I already put the windows 7 installation in a FAT32 active partition so i can plug the HDD via USB, since my notebook or other computers doesn't support boot via eSATA commonly, and it works. Now i want to do more partitions so i'm looking for a way to have a boot manager as active partitions that allows me to boot from different partitions in my HDD (win7, ubuntu installations for example) I want to know if you know any software to do this or you already have this system. Thanks and sorry i have too many grammar errors because english is not my native language :)

  • Preventing possible burnout in a junior dev, or perhaps I'm not doing enough?

    - by m.edmondson
    I'm a software developer with 5 years experience over 3 companies. Within the last year a junior (brand new to the industry) has started at my current employer. I believe he is an excellent developer, who always delivers and is skilled as solving complex problems. However I'm slightly concerned that he is possibly applying himself too much for the following reasons: He begins work approximately 2 hours before most (and is expected) In his free time he has developed an application that was clearly months worth of work that is specific to our employer I and the team are completely greatful for all he is doing, and is clearly an asset to our team. However I'm worried that this is not sustainable. I can almost see that he has the same enthusiasm that I had when I began coding for work, however over the years I've realised that extra curricular work not only doesn't progress your career, but eats into your all important free time. The question I'm asking is: Should I advise him to take things a bit more slowly? Or perhaps I need to learn from him and do more for my employer out of hours?

  • (PHP vs Python vs Perl) vs Ruby [closed]

    - by Dr.Kameleon
    OK, here's what : I've programmed in over 20 different languages and now, because of a large project I'm currently working on for Mac OS X (in Objective-C/Cocoa), I need to make a final decision on which language to use for my background scripting + plugin functionality. Definitely, one factor that'll ultimately influence my decision is which one I'm most familiar with, which is PHP (one of the ugliest languages around, which I however adore... lol), then Python / Perl (the "proven values"... )... and then Ruby (which, to me, is almost confusing and I've only played with it for some time.) Now, here's my considerations : (As previously mentioned) Being familiar with it (anyway, if X is better in my case, I really don't mind studying it from scratch...) Speed Good interaction with the Shell + ease of integration with my Cocoa application Btw, some of the reasons that made me wonder if Ruby would be a good choice is : The hype around it (although, I still don't get why; but that's probably just me...) My major competitor (we're actually talking about the same type of software here) is using Ruby for its backend scripting almost exclusively (ok, along with some BASH). Isn't Ruby considered slower e.g. than Perl? Why did he choose that? Simply, a matter of personal taste? So... your thoughts?

  • Virtualization of desktop

    - by Agares
    Hi! I'm thinking about virtualization of my laptop(for educational purposes). My idea is to install very light host OS and have all the rest as virtual machines. Microsoft's Hyper-V Standalone would be very good solution, but it's impossible to access virtual machine from computer, where the Hyper-V is the host(isn't it?). So, which virtualization software would be good for me? I wanna have virtualized Windows 7(and maybe some other windowses). My processor support Intel Virtualization Technology.
