• print web on dot matrix receipt printer

  - by nightingale2k1

  Hi, I need to print a receipt from my web based apps using dot matrix printer epson tm-u220d (pos printer). I need to know, should I generate the receipt in html or in plain text ? I ever saw some commands for dot matrix printer to change the font size, line feed etc .. but I don't remember that commands. if I have to use plain text I need to use that commands. anyone knows where i can get the references ? Thanks

• How do I run a vim script that alters the current buffer?

  - by Dan

  I'm trying to write a beautify.vim script that makes C-like code adhere to a standard that I can easily read. My file contains only substitution commands that all begin with %s/... However, when I try to run the script with my file open, in the manner :source beautify.vim, or :runtime beautify.vim, it runs but all the substitute commands state that their pattern wasn't found (patterns were tested by entering them manually and should work). Is there some way to make vim run the commands in the context of the current buffer? beautify.vim: " add spaces before open braces sil! :%s/\%>1c>\s\@<!{/ {/g " beautify for sil! :%s/for *( *\([^;]*\) *; *\([^;]*\) *; *\([^;]*\) *)/for (\1; \2; \3)/ " add spaces after commas sil! :%s/,\s\@!/, /g In my tests the first :s command should match (it matches when applied manually).

• Imagemagick command line in PHP

  - by charly

  Hello everyone, I've got the following two commands for imagemagick in the command line: convert in.png container-mask.png +matte -compose CopyOpacity -composite out.png composite container.png out.png -compose multiply final.png Those two commands include 3 files: in.png: the file that should be masked container-mask.png: the back/white mask of the areas of container.png where in.png should be visible container.png image that includes the container for in.png, the one that has been masked in black/white with container-mask.png Now the question is how to transpose this commands into PHP calls. I've played around quite a bit, but I can't make sense of the API at http://php.net/manual/en/book.imagick.php Thanks and Bests, Charly

• Best way to order menu items injected by an IoC/plugin Framework

  - by Daver

  One of the common things I've seen done in applications built on IoC/plugin frameworks is to add commands to menus or toolbars from the dynamically loaded plugins. For example, the application's default plugins supply actions like "New, Open, Save" that show up in the context menu for a certain item in the workspace. A new plugin may add "Mail, Post, Encrypt" commands, but where do those commands show up in relation to "New, Open, Save"? How can the application that is loading components through IoC impose order on the items that get injected? Does it require metadata from the plugins that give a hint on how to group or order the items? Does it use a config file of previously known menu names (or ids) to define the order (seems a little weak to me)? Or are "unknown" plugins treated as second class citizens and always get dumped into sub menus? Something I've never even imagined (which I'm hoping to see in the answers)

• Is there a single Git command to get the current tag, branch and commit?

  - by Koraktor

  I'm currently using a collection of three commands to get the current tag, branch and the date and SHA1 of the most recent commit. git describe --always --tag git log -1 --format="%H%n%aD" git rev-parse --abbrev-ref HEAD Which will output something like: 1.2.3-gdeadbeef deadbeef3b8d90071c24f51ac8f26ce97a72727b Wed, 19 May 2010 09:12:34 +0200 master To be honest, I'm totally fine with this. But I'm using these commands from Maven and anyone who'd used Maven before, knows how much things like external commands bloat the POM. I just want to slim down my pom.xml and maybe reduce execution time a bit.

• CMD Execption Handling C/C++

  - by ciyo

  I will use some CMD commands in my program and these commands might throw some exceptions. And as you know, when an exception accours, CMD writes its own error message the screen. But, I want to write my own error message. My question is this: Is there a way to block CMD messages and write only my own error messages? P.S. This is not a complex program. It executes CMD commands using System(). Example: Let's say, the user can rename and copy any files in the program. As you know, if the user does not enter file's path properly, an error message is showed on the screen. And I want that this error message never appears on the screen. Only my own error message is showed. Thank you!

• Looking for python lib to manage remote tasks

  - by Riz

  Hi, I have server with django on it, this server runs some manage.py commands and update database. Now I need to move some of this tasks to different servers. I don't want to allow remote db access and need some tool\lib to be able to start task on remote servers by main server's command and update tasks code/add new tasks. I have ssh access to every server, all servers run under debian and all code in python. I was thiking about creating my own xmpp based solution(server sends messages to slave servers with commands to execute, like "update task", "run task"), or maybe some low-level ssh based solution where main server logs to slave servers and executes bash commands. But I would be happy to hear any advices.

• Long list of if statements in Java

  - by steve

  Hi, Sorry I can't find a question answering this, I'm almost certain someone else has raised it before. My problem is that I'm writing some system libraries to run embedded devices. I have commands which can be sent to these devices over radio broadcasts. This can only be done by text. inside the system libraries I have a thread which handles the commands which looks like this if (value.equals("A") { doCommandA() } else if (value.equals"B") { doCommandB() } else if etc. The problem is that there are a lot of commands to it will quickly spiral to something out of control. Horrible to look out, painful to debug and mind boggling to understand in a few months time.

• Light-weight, free, database query tool for Windows?

  - by NoCatharsis

  My question is very similar to the one here except pertaining to a Windows tool. I am also referencing this table and what I found here with a Google search. However, I have no idea which tool would best meet my (very basic) purposes. I am currently using Excel with a basic ODBC connection string to query my database at work. However, Excel is pretty memory-heavy and a basic query tends to throw my computer into a 30 second stall-a-thon. Is there a free tool out there that is light-weight and can serve the same purpose when provided an ODBC connection and a SQL query? Also would prefer that it easily copies over to a spreadsheet as needed.

• Add dpkg .symbols or.shlibs to package made using checkinstall

  - by Hubert Kario

  I have created a simple package using checkinstall of the Oracle Instantclient client libraries, the package installs without problem and is seen in the system. Problem is, that checkinstall doesn't create /var/lib/dpkg/info/oracle-instantclient11.2-basic.symbols or /var/lib/dpkg/info/oracle-instantclient11.2-basic.shlibs files so when I try to create another package (with proper build scripts) that depends on oracle-instantclient11.2-basic the build fails with dpkg-shlibdeps: error: no dependency information found for \ /usr/lib/libclntsh.so.11.1 (used by \ debian/libopendbx1-oracle/usr/lib/opendbx/liboraclebackend.so.1.2.0). dh_shlibdeps: dpkg-shlibdeps \ -Tdebian/libopendbx1-oracle.substvars \ debian/libopendbx1-oracle/usr/lib/opendbx/liboraclebackend.so.1.2.0 \ returned exit code 2 make: *** [binary-arch] Error 9 Is there an easy way to automatically create a package with .symbols or .shlibs files?

• unwanted password prompt pops up on web server?

  - by Paul

  my web server randomly asks for a password as though basic authentication is turned on. It's an IIS 7 web server and you have to specifically install basic authentication in the roles section. It isn't installed. The message that pops up is "Warning: This server is requesting that your username and password be sent in an insecure manner (basic authentication without a secure connection)" I cannot reproduce the problem but a number of customers have reported the problem and it only seems to appear to a small number of customers. It pops up when they visit the homepage, nothing is generated by the IIS logs to indicate a password box is being served (e.g. no 401 errors etc) Can anyone offer any advice? Thanks

• What is a good web interface for remote linux load monitoring?

  - by Jakobud

  I'm looking for some type of remote linux monitoring software that you can view using a web interface. And I'm not just looking for the basic load information. I'm also looking for process information, similar to the info that you get from TOP. Like I'd just like to be able to pop open this webpage to view whats going on with the server at a moments notice. For example, perhaps just a basic PHP page that is on the server that uses basic AJAX to display and refresh results from the TOP command in the page. I was thinking about writing something like this, but I don't want to reinvent the wheel.

• GRE subject Computer science

  - by Maddy.Shik

  How do I prepare for the GRE Computer Science subject test? Are there any standard text books I should follow? Agree that its under graduation level and one doesn't need to dig to deep for it. I have done my computer engineering from a college who ranks in top 20 in India. So may be my curriculum has not been that good as compared to international students. Since now i want to get admission in to world renowned university's Ph. D. program. I want to enhance my basic skills up to a level to beat other international students in competition. I want to know good book references which are recommended by professors in international school like CMU, MIT, Standford etc. Like for Algorithms Coreman is considered very good. Good books builds concepts from very basic so that one doesn't need to mug up even a basic concepts. Coreman is just too good with good blend of Mathematics and programming concepts. Definitely Test paper are must but that can be practiced once one has read text books thoroughly. Besides its been 2 years i passed out from college so its is essential for me to revise all concepts from text books. Please tell me standard text books for each subject like Computer Architecture, Database Design, Operating Systems, Discrete Maths etc.

• C# Adds Optional and Named Arguments

  Earlier this month Microsoft released Visual Studio 2010, the .NET Framework 4.0 (which includes ASP.NET 4.0), and new versions of their core programming languages: C# 4.0 and Visual Basic 10. In designing the latest versions of C# and VB, Microsoft has worked to bring the two languages into closer parity. Certain features available in C# were missing in VB, and vice-a-versa. Last week I wrote about Visual Basic 2010's language enhancements, which include implicit line continuation, auto-implemented properties, and collection initializers - three useful features that were available in previous versions of C#. Similarly, C# 4.0 introduces new features to the C# programming language that were available in earlier versions of Visual Basic, namely optional arguments and named arguments. Optional arguments allow developers to specify default values for one or more arguments to a method. When calling such a method, these optional arguments may be omitted, in which case their default value is used. In a nutshell, optional arguments allow for a more terse syntax for method overloading. Named arguments, on the other hand, improve readability by allowing developers to indicate the name of an argument (along with its value) when calling a method. This article examines how to use optional arguments and named arguments in C# 4.0. Read on to learn more!

• What kinds of demos are good to make for a software engineer job

  - by user23012

  I have created my cv site and sent out my demos for a while now, but most of my demos are either from my course or games related since my course was a games programming course, I was wondering what kind of demos are good to show off my skills in programming in general. These are what i already have Pennies:just a simple game first coursework i did. Compiler:coursework for compiler writing module Pongout: basic a pong game in 68k using colour detection Snake: snake in 68k same thing as the pong Game Cube Maze: gamecube work BeatmyBot: basic Ai Basic plat-former game: 2d game with different types of collision Turing Lambda Simulation: my dissertation Turing machine simulated in Miranda. alpha and Beta reduction,and SKI calculus simulated in the Turing machine. What I am asking here is what kind of demos are good to add or have, i have been looking and have hit a tough spot I cant think of anything to make more than games. so for a general graduate software engineer what types would be good examples? EDIT: since responding to the comments bellow well for what languages well my main one would be C++, followed by Java, Erlang and abit of Haskell

• I know fundamental programming. But how do I get started in game development now?

  - by Rohan Menon

  I'm a 20 year old programming student. I know fundamental programming in BASIC, C, C++ and JAVA. What I wanted to ask is, where do I go from here? Are there any books that the community can mention that will help me develop a game or at least learn game development? I've had a lot of ideas and really want to make some sort of prototype to see if I'm suited for the industry. I really don't mind learning any new languages but I need to know what I should begin with. A good book that will help with a little more understanding as I go up will be very helpful. Maybe a tutorial to develop some basic 2D games like a side-scroller, snake or pocket tanks in an easy to understand SDK? I know that to get some credit under your belt, you need to be able to make a few games on your own. Also, what platform should I start on? The PC, iOS or Android (as an introduction) for now. I don't want to get into high level game design just yet. Just something a bit basic to help out in future development. Anything pointing me in the right direction will be really really helpful. Edit: Also, I want to say that I'm looking towards this from a game designer's point of view more than a game programmer. I want suggestions on any SDKs or easy to use programs I can use to understand game design. Then delve deeper into the programming after that. Not as employment but as developing your own games (for now).

• GPTsync mismatch problem

  - by user86762

  I have a hybrid disk. After trying to copy some files from another disk to this one, I lost my OSX and Ubuntu boot capability. Ran gptsync and got: Current GPT partition table: # Start LBA End LBA Type 1 34 1987 BIOS Boot Partition 2 1988 1029662719 Basic Data 3 1029662720 2108995583 Basic Data 4 2108995584 2109405183 EFI System (FAT) 5 2109405184 2517004287 Mac OS X HFS+ 6 2517266432 2667417599 Mac OS X HFS+ 7 2667417600 3900229631 Basic Data 8 3900230504 3907029118 Linux Swap Current MBR partition table: # A Start LBA End LBA Type 1 1 3907029167 ee EFI Protective Status: MBR table must be updated.

[y/N] Clearly the MBR table is damaged or mismatched. But it does not reflect the correct GPT table partitions at all. How do I get the MBR repaired to match the GPT table (up to the 4 part limit of course)? The question is simply - Do I blindly say Yes to gptsync's suggestion? It looks sort of ok but not exactly so...Advice please on interpreting the above output to get my disk usable would be greatly appreciated. Thank You!

• Ubiquitous Language and Custom types

  - by EdvRusj

  Note that my question is referring to those attributes that even on their own already represent a concept ( ie on their own provide a cohesive meaning ). Thus such attribute needs no additional functional support and as such is self-contained. I'm also well-aware that even with self-contained attributes the custom types may prove beneficial ( for example, they give the ability to add new behavior later, when business requirements change ). Thus, my question focuses only on whether custom types for self-contained attributes really enrich Ubiquitous Language UL a) I've read that in most cases, even simple, self-contained attributes should have custom, more descriptive types rather than basic value types ( double, string ... ), because among other things, descriptive types add to the UL, while the use of basic types instead weakens the language. I understand the importance of UL, but how does having a basic type for a self-contained attribute weaken the language, since with self-contained attributes the name of the attribute already adequately describes the concept and thus contributes to the UL vocabulary? For example, the term person_age already adequately explains the concept of quantifying the number of years a person has: class Person { string person_age; } so what could we possibly gain by also introducing the term ThingAge to the UL: class person { ThingAge person_age; } thanks

• When NOT to use a framework

  - by Chris

  Today, one can find a framework for just about any language, to suit just about any project. Most modern frameworks are fairly robust (generally speaking), with hour upon hour of testing, peer reviewed code, and great extensibility. However, I think there is a downside to ANY framework in that programmers, as a community, may become so reliant upon their chosen frameworks that they no longer understand the underlying workings, or in the case of newer programmers, never learn the underlying workings to begin with. It is easy to become specialized to a degree that you are no longer a 'PHP programmer' (for example), but a "Drupal programmer", to the exclusion of anything else. Who cares, right? We have the framework! We don't need to know how to "do it by hand"! Right? The result of this loss of basic skills (sometimes to the extent that programmers who don't use frameworks are viewed as "outdated") is that it becomes common practice to use a framework where it is not required or appropriate. The features the framework facilitates wind up confused with what the base language is capable of. Developers start using frameworks to accomplish even the most basic of tasks, so that what once was considered a rudimentary process now involves large libraries with their own quirks, bugs, and dependencies. What was once accomplished in 20 lines is now accomplished by including a 20,000 line framework AND writing 20 lines to use the framework. Conversely, one does not want to reinvent the wheel. If I'm writing code to accomplish some basic, common little task, I might feel like I am wasting my time when I know that framework XYZ offers all the features I am after, and a whole lot more. The "whole lot more" part still has me worried, but it doesn't seem that many even consider it anymore. There has to be a good metric to determine when it is appropriate to use a framework. What do you consider the threshold to be, how do you decide when to use a framework, or, when not.

• Can anyone point me to some open source directX rendering engines or frameworks? [on hold]

  - by Jim

  I'm completely new to graphics API programmming, but not at all new to the theory and principle operation of game engines and rendering engines. That being said, I want to do some experiments of rendering very dense geometry scenes in a basic rendering engine or game engine. I don't need a lot of bells and whistles. What I need is enough control that I can implement my own scene graph algorithms and control the rendering pipeline very specifically. My ideal candidate engine would be either a rendering engine or game engine with a modular design that might be ready to go out of the box but would be simple enough in case I need to rip out some of the guts in the rendering management and implement my own. It's a tough call because I'm right at the level where it's almost better to go from scratch, but there's no sense in having to build every single basic thing such as heirarchical transforms, etc. I just want to work with rendering optimization to push dense geometry for maximum FPS. Does anyone have a suggestion for an engine or basic framework to use? I requested DirectX in my title because I figured it would likely be better supported and less likely for me to run into some obscure less-documented problem. But OpenGL might be acceptable if the recommended framework was definitely better than my other options. EDIT: I should add that I really want GPU tessellation support (part of adding to the density of geometry detail).

• Grub2 cannot detect Windows 8

  - by MetaChrome

  At installation it did not detect Windows. I mounted the Windows partition and have run os-prober with no results returning. I am able to boot Windows or Ubuntu by specifying the partition in UEFI boot order. The bios does not appear to allow booting with legacy. SecureBoot is on. This is with Ubuntu 12.04 LTS on a Inspiron 15. Here is the gdisk: 1 2048 1026047 500.0 MiB EF00 EFI system partition 2 1026048 1107967 40.0 MiB FFFF Basic data partition 3 1107968 1370111 128.0 MiB 0C01 Microsoft reserved part 4 1370112 2394111 500.0 MiB 2700 Basic data partition 5 2394112 544743423 258.6 GiB 0700 Basic data partition 6 606183424 625140399 9.0 GiB 2700 Microsoft recovery part 7 544743424 545230847 238.0 MiB 0700 (/boot) 8 545230848 556949503 5.6 GiB 8200 (swap) 9 556949504 606181375 23.5 GiB 0700 (/) When installing ubuntu, I believe I specified that the bootloader be installed on /dev/sda. I added the following to /etc/grub.d/40_custom but booting ubuntu did not offer a grub menu: menuentry "Windows 8" { set root = "(hd0,4)" chainloader +1 } When booting I think I see "EFI Disk error" flash very quickly before Ubuntu starts booting.

• How should a non-IT manager secure the long-term maintenance and development of essential legacy software?

  - by user105977

  I've been hunting for a place to ask this question for quite a while; maybe this is the place, although I'm afraid it's not the kind of "question with an answer" this site would prefer. We are a small, very specialized, benefits administration firm with an extremely useful, robust collection of software, some written in COBOL but most in BASIC. Two full-time consultants have ably maintained and improved this system over more than 30 years. Needless to say they will soon retire. (One of them has been desperate to retire for several years but is loyal to a fault and so hangs on despite her husband's insistence that golf should take priority.) We started down the path of converting to a system developed by one of only three firms in the country that offer the type of software we use. We now feel that although this this firm is theoretically capable of completing the conversion process, they don't have the resources to do so timely, and we have come to believe that they will be unable to offer the kind of service we need to run our business. (There's nothing like being able to set one's own priorities and having the authority to allocate one's resources as one sees fit.) Hardware is not a problem--we are able to emulate very effectively on modern servers. If COBOL and BASIC were modern languages, we'd be willing to take the risk that we could find replacements for our current consultants going forward. It seems like there ought to be a business model for an IT support firm that concentrates on legacy platforms like this and provides the programming and software development talent to support a system like ours, removing from our backs the risks of finding the right programming talent and the job of convincing younger programmers that they can have a productive, rewarding career, in part in an old, non-sexy language like BASIC. Where do I find such firms?
