  • 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.

  • The most mind-bending programming language?

    - by Xepoch
    From a reasonably common programming language, which do you find to be the most mind-bending? I have been listening to a lot of programming podcasts and taking some time to learn some new languages that are being considered upcoming, and important. I'm not necessarily talking about BrainFuck, but which language would you consider to be one that challenges the common programming paradigms? For me, I did some functional and logic (ex. Prolog) programming in the 90s, so can't say that I find anything special there. I am far from being an expert in it, but even today the most mind-bending programming language for me is Perl. Not because "Hello World" is hard to implement but rather there is so much lexical flexibility that some of the hardest solutions can be decomposed so poetically that I have to walk outside away from my terminal to clear my head. I'm not saying I'd likely sell a commercial software implementation, just that there is a distinct reason Perl is so (in)famous. Just look at the basic list of books on it. So, what is your mind-bending language that promotes your better programming and practices?

  • Refactoring and Open / Closed principle

    - by Giorgio
    I have recently being reading a web site about clean code development (I do not put a link here because it is not in English). One of the principles advertised by this site is the Open Closed Principle: each software component should be open for extension and closed for modification. E.g., when we have implemented and tested a class, we should only modify it to fix bugs or to add new functionality (e.g. new methods that do not influence the existing ones). The existing functionality and implementation should not be changed. I normally apply this principle by defining an interface I and a corresponding implementation class A. When class A has become stable (implemented and tested), I normally do not modify it too much (possibly, not at all), i.e. If new requirements arrive (e.g. performance, or a totally new implementation of the interface) that require big changes to the code, I write a new implementation B, and keep using A as long as B is not mature. When B is mature, all that is needed is to change how I is instantiated. If the new requirements suggest a change to the interface as well, I define a new interface I' and a new implementation A'. So I, A are frozen and remain the implementation for the production system as long as I' and A' are not stable enough to replace them. So, in view of these observation, I was a bit surprised that the web page then suggested the use of complex refactorings, "... because it is not possible to write code directly in its final form." Isn't there a contradiction / conflict between enforcing the Open / Closed Principle and suggesting the use of complex refactorings as a best practice? Or the idea here is that one can use complex refactorings during the development of a class A, but when that class has been tested successfully it should be frozen?

  • Watch videos from a remote computer on the LAN on ubuntu

    - by tapan
    I want to watch the videos on a friends computer on the LAN without having to download it. Both of us are running ubuntu. Now one way is to ssh to his computer, cd to the directory where the video is and run the falling command: cat video.avi | ssh me@mycomputer mplayer - This works. However the problem is that I cannot seek inside the video as in can't go forward or backward in it. Is there a method by which I can watch the videos and also seek in them ? I can install any software on his comp and my comp to aid this process. I have root level access on both computers. Any suggestions ?

  • What is IPKVM and why would I need that to install SQL Server on my Web Server?

    - by Eric
    Hello. I have a dedicated server, and will be installing SQL Server. However, my hosting company said they can connect an external CD ROM drive and give me KVM over IP to install SQL Server. My question is, what is IPKVM, and how does it work? Do I need special hardware or software on my side to use it....or do I just connect via remote desktop? Also, why can't I remote into my server through remote desktop instead of using KVM over IP?

  • Windows xp : possible virus

    - by dotnet-practitioner
    I think my son downloaded some thing from internet and possibly infect the computer. The Google chrome browser will not start any more and after an hour of using computer he gets some sort of blue screen saying that memory is being dumped. I don't want to format the hdd and reinstall at this time. Can I salvage the machine by some anti virus? Questions: 1. How do I detect what kind of virus do I have? 2. What kind of free anti virus software do I download to fix this problem? Thanks

  • Problems with wired ethernet connection Ubuntu 11.10

    - by Andrew Fielden
    After some partition shuffling, I've got a problem on my 11.10 system. The wired ethernet interface fails to come up, although the wireless interface is working. I'm using NetworkManager. I thought this may be a problem with NetworkManager, so I checked the config files, which look ok. I then tried re-installing the package, but this didn't resolve the issues. I'm not sure at this point if the problem is due to software configuration, or a hardware problem. I've also tried the cable in other router ports, but same problem. The symptoms are:- System settings - Network reports that the cable is unplugged (it isn't) ifconfig reports the following eth0 Link encap:Ethernet HWaddr f0:4d:a2:a2:a7:fe UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:10 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:792 (792.0 B) TX bytes:0 (0.0 B) Interrupt:46 Base address:0xe000 My /etc/network/interfaces file has the following: auto lo iface lo inet loopback My /etc/resolv.conf file has the following: # Generated by NetworkManager The router's red light is on for this port dmesg reports ADDRCONF(NETDEV_UP): eth0: link is not ready

  • How do I boot a virtual machine image from my network?

    - by Haabda
    I have many machines which require the same configurations. My goal is to boot them all from the network and load a virtual machine. It would be wonderful to have one image for all of our customer service machines. That way, I could load the virtual image, perform updates, and know the next time they boot up they will have all the changes. Ideally, the machines would store the image locally and only download a new image if there has been a change. With all the information out there on "desktop virtualization", "PXE booting", and "virtual machines", I feel lost. I have been reading for hours and feel like I have only just scratched the surface. I would like to do this using open source or free software. Any suggestions?

  • 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.

  • Question about ubuntu untrusted source, gpg, keyserver

    - by ???
    I have mirrored the ubuntu archive repository (I must say it's rather huge). Then, I can apt-get install with no problem, but it prompts with following warning: WARNING: The following packages cannot be authenticated! xxxx, xxxx, ... Install these packages without verification [y/N]? Well, you can always install it. But, I can't install from the ubuntu software GUI. Which require trusted source. So, 1. How to force the GUI to install untrusted package? 2. Should I configure GPG to receive some public keys? (I've already installed ubuntu-keyring, debian-keyring, but it still untrusted) 3. Should I configure GPG to receive unknown keys from some specific keyservers, automatically?

  • Profit : August, 2012

    - by user462779
    August 2012 issue of Profit is now available online. Way back in 2003, I wrote my first feature for Profit. It was titled “Everything You Always Wanted to Know About Application Servers (But Were Afraid To Ask),” and it discussed “cutting-edge” technologies like portals and XML and the brand-new Java Platform, Enterprise Edition (Java EE; we’re now on Java EE 7). But despite the dated terms I used in my Profit debut, I noticed something in rereading that old story that has stayed constant: mid-tier technology is where innovative enterprise IT projects happen. It may have been XML in 2003, but it’s SOA in 2012. While preparing the August issue of Profit was more than just a stroll down memory lane for me, it has provided a nice bit of perspective about what changes and what doesn’t in this dynamic IT industry. Technologies continuously evolve—some become standard practice, some are revived or reinvented, and some are left by the wayside. But the drive to innovate and the desire to succeed are business principles that never go out of fashion. Also, be sure to check out the Profit JD Edwards Special Issue 2012 (PDF), featuring partner profiles, customer successes, and Oracle executive interviews.

  • VNC application/terminal server

    - by sebastian nielsen
    Which software should I use, if I want to set up a linux VNC terminal server that works in this way: The VNC server should be able to accept up to X simultanous connections on the same port 5900. The VNC server should use 640x480 on 8 or 16bit color. When the VNC server receives the connection, it should start a new "session" for a user, and auto-launch a specific linux application for that user. If the application is killed, crashes, or is exited in any way, user should be disconnected (kicked) from server. If the user disconnect, the application should be killed in a "graceful way", that allows the application to cleanup. (There should be no way to "pick up" a old session) Any ideas?

  • Working with fubar/refuctored code

    - by Keyo
    I'm working with some code which was written by a contractor who left a year ago leaving a number of projects with buggy, disgustingly bad code. This is what I call cowboy PHP, say no more. Ideally I'd like to leave the project as is and never touch it again. Things break, requirements change and it needs to be maintained. Part A needs to be changed. There is a bug I cannot reproduce. Part A is connect to parts B D and E. This kind of work gives me a headache and makes me die a little inside. It kills my motivation and productivity. To be honest I'd say it's affecting my mental health. Perhaps being at the start of my career I'm being naive to think production code should be reasonably clean. I would like to hear from anyone else who has been in this situation before. What did you do to get out of it? I'm thinking long term I might have to find another job. Edit I've moved on from this company now, to a place where idiots are not employed. The code isn't perfect but it's at least manageable and peer reviewed. There are a lot of people in the comments below telling me that software is messy like this. Sure I don't agree with the way some programmers do things but this code was seriously mangled. The guy who wrote it tried to reinvent every wheel he could, and badly. He stopped getting work from us because of his bad code that nobody on the team could stand. If it were easy to refactor I would have. Eventually after many 'just do this small 10minute change' situations had ballooned into hours of lost time (regardless of who on the team was doing the work) my boss finally caved in it was rewritten.

  • What do I need to know to design a language and write a interpreter for it?

    - by alFReD NSH
    I know this question has been asked and even there are thousands of books and articles about it. But the problem is that there are too many, and I don't know are they good enough, I have to design a language and write a interpreter for it. The base language is javascript (using nodejs) but it's ok if the compiler was written in another language that I can use from node. I had done a research about compiler compilers in JS, there is jison (Bison implementaion in JS), waxeye, peg.js. I decided to give jison a try, due to the popularity and its being used by coffee script, so it should be able to cover my language too. The grammar definition syntax is similar to bison. But when I tried read the bison manual it seemed very hard to understand for me. And I think it's because I don't know a lot of things about what I'm doing. Like I don't what is formal language theory. I am experienced in Javascript (I'm more talented in JS than most average programmers). And also know basic C and C++ (not much experience but can write a working code for basic things). I haven't had any formal education, so I may not be familiar with some software engineering and computer science principles. Though everyday I try to grasp a lot of articles and improve. So I'm asking if you know any good book or article that can help me. Please also write why the resource you're suggesting is good. --update-- The language I'm trying to create, is not really complicated. All it has is expressions (with or without units), comparisons and logical operators. There are no functions, loops, ... The goal is to create a language that non-programmers can easily learn. And to write customized validations and calculations.

  • HPC Cluster planning workflow?

    - by Veronica
    After three days of intensive Google searching, I have not found any high-level workflow of how to build a low profile - cheap - computing cluster (we are not interested in HA yet). This is just a front-end plus a node for now. We want to start small with rockscluster, provide a web-based server for offering services, and then add nodes as our budget increases. We're small company, so we haven't enough human resources to implement it smoothly. Here are some facts about our environment: Our hardware is not constant (we will add nodes). Our workload will vary (in the order from 200Mb - 1Tb) Our software will change (scientific applications for data mining) Do you know any visual workflow, worksheet, chart, describing the general necessary steps to begin our cluster planning?

  • Firmware/driver for Broadcom wifi card, PowerBook G4 running Ubuntu 12.04 [duplicate]

    - by user107831
    This question already has an answer here: How to Install Broadcom Wireless Drivers 40 answers This is my first time working with Ubuntu (or Linux), so please be patient. I am running Ubuntu 12.04-powerpc "Precise Pangolin" on a Mac PowerBook G4 with 1.67GHz processor. The firmware/driver for the wifi card is missing. For reasons not worth explaining, I cannot physically plug the computer into the network. I have another computer, a MacBook Pro running OSX, from which I can download files and port them by USB thumb drive. The wifi card in the PowerBook G4 is by Broadcom. The chip is BCM4306, rev. 3. The PCI number is 14e4:4302. I have downloaded b43-fwcutter_015-14_powerpc.deb and dropped it into the Home folder on the Ubuntu machine. However, it will not install. When I double-click, it opens with Ubuntu SoftwareCenter, but the "Install" button is inactive: I can't click it. There's a message beside the inactive button saying, "An older version of 'b43-fwcutter' is available in your normal software channels. Only install this file if you trust the origin." If I "right-click" the .deb file and open with Archive Manager, it shows me the "DEBIAN" and "usr" folders, but I'm unsure what to do from there...and fairly certain this is not the right way to do things. Maybe I have the wrong version of b43-fwcutter for my machine/version of Ubuntu? The documentation for this problem is a mess. It refers to all sorts of out-of-date Ubuntu versions and to an array of different "cutter" and firmware files. Maybe I'd be able to figure this out if I were a more seasoned Ubuntu user, but I have no idea why Sofware Center won't let me do the install. I would be VERY grateful for an explanation of how to get the wifi card working on this machine again. Thank you!

  • Linux file permissions not being preserved

    - by yellavon
    I am deploying some custom software as root (a necessity for this situation). I set the owner/group to user1:user1 and set all the files to 644 beforehand in shell, then copy and deploy with ant. However, when files get copied over from the deployment directory, the ownership changes back to root and all the files install with 666 permissions. This seems to occur whether the file is overwritten or newly created. I believe there is a way to set an option in cp, mv commands to preserve permissions, but that would be a lot of commands to change. How can I fix this? Is there some setting I can change temporarily for root so the install always preserves the file permissions?

  • 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?

  • Edd strikes again &ndash; IronRuby for Rubyists on InfoQ

    - by Eric Nelson
    Colleague, friend and generally top guy on IronRuby Edd Morgan has just been published over on InfoQ. To wet the appetite… a snippet or three. IronRuby for Rubyists IronRuby is Microsoft's implementation of the Ruby language we all know and love with the added bonus of interoperability with the .NET framework — the Iron in the name is actually an acronym for 'Implementation running on .NET'. It's supported by the .NET Common Language Runtime as well as, albeit unofficially, the Mono project. You'd be forgiven for harbouring some question in your mind about running a dynamic language such as Ruby atop the CLR - that's where the DLR (Dynamic Language Runtime) comes in. The DLR is Microsoft's way of providing dynamic language capability on top of the CLR. Both IronRuby and the DLR are, as part of Microsoft's commitment to open source software, available as part of the Microsoft Public License on GitHub and CodePlex respectively… And Metaprogramming with IronRuby The art and science of metaprogramming — especially in Ruby, where it's an absolute joy — is something that could very easily span an entire article. As you would hope, IronRuby code is fully able to manipulate itself allowing you to bend your classes to your whim just as you would expect with a good dynamic language… And Riding the irails? So let's get to the point. I think it's a solid bet to make that a large proportion of Ruby programmers are familiar with the Rails framework - perhaps it's even safe to assume that most were first led to the Ruby language by the siren song of the Rails framework itself. Long story short, IronRuby is compatible enough to run your Rails app… Now… get yourself over to the full article and also check out some of Edds other work below.

  • (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?

  • How do I copy a package from Debian to my PPA?

    - by Bernhard Reiter
    I'd like to add the latest gourmet package from Debian sid to our team's PPA so Ubuntu users who would like to run an up-to-date version of Gourmet can add that PPA to their software sources. (Dependency-wise, that shouldn't be much of an issue as pretty much all our current dependencies are already available in all currently supported Ubuntu versions.) I've downloaded the *.dsc file and debian and orig tarballs, and even figured out I could use this for the package's source.changes file. I also downloaded the Debian maintainer's public key so dput can validate the package. I then tried to upload the package to our PPA using dput ppa:~gourmet/ppa gourmet_0.17.3-1_source.changes (I also tried without the tilda.) This seemed to succeed, but I didn't get a confirmation email, and no packages are now displayed at our PPA, which leads me to believe that the package was rejected because the Debian maintainer's key is obviously not among our team members' keys. So what's the easiest way to "copy" a package from Debian (sid) to a Launchpad PPA? Do I really need to rebuild the entire package locally before I can upload it?

  • Microsoft Office- I purchased it but it is telling me that my license has been used too many times.

    I purchased a copy of Microsoft Office Student Edition last year. My computer's hard drive crashed which meant that I had to reinstall the software and use the serial code again. It is now telling me though that the number of uses has been exceeded. Is there a way to tell Microsoft that I'm trying to validate on the same machine that I was already operating on? I really don't want to have to purchase it again to run on the same machine that it was already running on.
