• Stuck in logon loop

  - by MJeffryes

  Here's the deal. I set up a computer with Ubuntu 10.04 for my grandmother. Everything worked fine. I connected it to the internet at her house today. After rebooting the computer I found that the computer would kick you back to the logon screen if you attempted to logon to her account. It worked fine logging on to my admin account, and also in Gnome's safe mode. I thought it had resolved itself, but turns out it hadn't, and now I don't have physical access to the computer, plus the remote connection I'd hoped to use only works intermittently. I need some suggestions for troubleshooting for when I'm at her house at some point next week. Ask for any more details, but I'm afraid I won't be able to provide many more until I've checked it out in person, since she is basically unable to use a computer beyond web browsing. Thanks in advance!

• Software purchases & accounts issue

  - by user1735003

  I have installed 13.10 on a new computer and want to tranfer my purchase (Braid) there. I have read this page about how to do this. However, when I log in to https://software-center.ubuntu.com/subscriptions, nothing appears. My guess is that when I purchased this game, I used an older email address than the one I am currently using. Ideally I would like to be able to transfer this purchase to my current ubuntu one account. Or, if this is not possible, at least to have a chance to know with which account this purchase has been done so I can have a try to reinstall it somewhere else. NB: In the Ubuntu Software Center on my older computer the game is still there and marked as "already purchased". EDIT: This is not an upgrade issue, as my old computer has not been upgraded to 13.10, and my newer computer is, well, new, 13.10 being its first OS. Note that I don't see my purchases on the software center web site on my old as well as my new computer, which makes sense.

• Old HP computer powers off after seconds, hard drive still spins. Power supply? Motherboard?

  - by Chase

  Someone called me saying their computer keeps shutting off. I brought it home to troubleshoot. It's an HP Pavilion 513c. The computer powers on normally but almost immediately powers off. Sometimes it manages to make it to a fully loaded desktop and other times it powers off during the boot process. The hard drive still spins but there is no video and the CPU fans quit spinning. The power has to be unplugged before you can turn it back on again. I'm thinking it's either a motherboard or power supply issue. I don't have a spare of either component laying around to test with. Any guess on which part is more likely to be the culprit? Thanks.

• "This file came from another computer..." - how can I unblock all the files in a folder without having to unblock them individually?

  - by Schnapple

  Windows XP SP2 and Windows Vista have this deal where zone information is preserved in downloaded files to NTFS partitions, such that it blocks certain files in certain applications until you "unblock" the files. So for example if you download a zip file of source code to try something out, every file will display this in the security settings of the file properties "This file came from another computer and might be blocked to help protect this computer" Along with an "Unblock" button. Some programs don't care, but Visual Studio will refuse to load projects in solutions until they've been unblocked. While it's not terribly difficult to go to every project file and unblock it individually, it's a pain. And it does not appear you can unblock multiple selected files simultaneously. Is there any way to unblock all files in a directory without having to go to them all individually? I know you can turn this off globally for all new files but let's say I don't want to do that

• What output and recording ports does the Java Sound API find on your computer?

  - by Dave Carpeneto

  Hi all - I'm working with the Java Sound API, and it turns out if I want to adjust recording volumes I need to model the hardware that the OS exposes to Java. Turns out there's a lot of variety in what's presented. Because of this I'm humbly asking that anyone able to help me run the following on their computer and post back the results so that I can get an idea of what's out there. A thanks in advance to anyone that can assist :-) import javax.sound.sampled.*; public class SoundAudit { public static void main(String[] args) { try { System.out.println("OS: "+System.getProperty("os.name")+" "+ System.getProperty("os.version")+"/"+ System.getProperty("os.arch")+"\nJava: "+ System.getProperty("java.version")+" ("+ System.getProperty("java.vendor")+")\n"); for (Mixer.Info thisMixerInfo : AudioSystem.getMixerInfo()) { System.out.println("Mixer: "+thisMixerInfo.getDescription()+ " ["+thisMixerInfo.getName()+"]"); Mixer thisMixer = AudioSystem.getMixer(thisMixerInfo); for (Line.Info thisLineInfo:thisMixer.getSourceLineInfo()) { if (thisLineInfo.getLineClass().getName().equals( "javax.sound.sampled.Port")) { Line thisLine = thisMixer.getLine(thisLineInfo); thisLine.open(); System.out.println(" Source Port: " +thisLineInfo.toString()); for (Control thisControl : thisLine.getControls()) { System.out.println(AnalyzeControl(thisControl));} thisLine.close();}} for (Line.Info thisLineInfo:thisMixer.getTargetLineInfo()) { if (thisLineInfo.getLineClass().getName().equals( "javax.sound.sampled.Port")) { Line thisLine = thisMixer.getLine(thisLineInfo); thisLine.open(); System.out.println(" Target Port: " +thisLineInfo.toString()); for (Control thisControl : thisLine.getControls()) { System.out.println(AnalyzeControl(thisControl));} thisLine.close();}}} } catch (Exception e) {e.printStackTrace();}} public static String AnalyzeControl(Control thisControl) { String type = thisControl.getType().toString(); if (thisControl instanceof BooleanControl) { return " Control: "+type+" (boolean)"; } if (thisControl instanceof CompoundControl) { System.out.println(" Control: "+type+ " (compound - values below)"); String toReturn = ""; for (Control children: ((CompoundControl)thisControl).getMemberControls()) { toReturn+=" "+AnalyzeControl(children)+"\n";} return toReturn.substring(0, toReturn.length()-1);} if (thisControl instanceof EnumControl) { return " Control:"+type+" (enum: "+thisControl.toString()+")";} if (thisControl instanceof FloatControl) { return " Control: "+type+" (float: from "+ ((FloatControl) thisControl).getMinimum()+" to "+ ((FloatControl) thisControl).getMaximum()+")";} return " Control: unknown type";} } All the application does is print out a line about the OS, a line about the JVM, and a few lines about the hardware found that may pertain to recording hardware. For example on my PC at work I get the following: OS: Windows XP 5.1/x86 Java: 1.6.0_07 (Sun Microsystems Inc.) Mixer: Direct Audio Device: DirectSound Playback [Primary Sound Driver] Mixer: Direct Audio Device: DirectSound Playback [SoundMAX HD Audio] Mixer: Direct Audio Device: DirectSound Capture [Primary Sound Capture Driver] Mixer: Direct Audio Device: DirectSound Capture [SoundMAX HD Audio] Mixer: Software mixer and synthesizer [Java Sound Audio Engine] Mixer: Port Mixer [Port SoundMAX HD Audio] Source Port: MICROPHONE source port Control: Microphone (compound - values below) Control: Select (boolean) Control: Microphone Boost (boolean) Control: Front panel microphone (boolean) Control: Volume (float: from 0.0 to 1.0) Source Port: LINE_IN source port Control: Line In (compound - values below) Control: Select (boolean) Control: Volume (float: from 0.0 to 1.0) Control: Balance (float: from -1.0 to 1.0)

• Dedicated hard disk for SE dbname.dbs files & dedicated ramdisk for /tmp files.

  - by Frank Computer

  INFORMIX-SE 7.2: I would like to dedicate a hard disk, exclusively for my dbname.dbs directory which holds all the .dat and .idx files, and create a ramdisk for my /tmp temporary files in order to improve performance. I would also like to strip down the OS from any unecessary files and processes to minimize overhead for my dedicated application. Is this a good idea and are there any roadmaps for accomplishing this?

• Always can't separate these guys: ascending and descending! Are there good examples?

  - by mystify

  As a non-english dude, I have trouble differentiating this. When I try to translate this into my language, I get something weird like "go up" for ascending. So lets say I want to sort the names of all my pets alphabetically. I want that A comes first, then B, then C... and so on. So since the alphabet is not a number for me, my brain refuses to grok what's "going up". A = 0? B = 1? C = 2? If yes, then ascending would be what I'm most of the time looking for. Table would start showing A, then B, then C... Or is that the other way around? Must I look from the bottom of the table, up? And with numbers: If it's an ascending order, the smallest comes first? (would seem logical...) Can someone post a short but good example for what is an ascending sort order, and what is an descending sort order? And does that apply to whatever platform, programming language, API, etc.?

• Any suggestions for good automated web load testing tool?

  - by fmunkert

  What are some good automated tools for load testing (stress testing) web applications, that do not use record and replay of HTTP network packets? I am aware that there are numerous load testing tools on the market that record and replay HTTP network packets. But these are unsuitable for my purpose, because of this: The HTTP packet format changes very often in our application (e.g. when we optimize an AJAX call). We do not want to adapt all test scripts just because there is a slight change in HTTP packet format. Our test team shall not need to know any internals about our application to write their test scripts. A tool that replays HTTP packets, however, requires the team to know the format of HTTP requests and responses, such that they can adapt details of the replayed HTTP packets (e.g. user name). The automated load testing tool I am looking for should be able to let the test team write "black box" test scripts such as: Invoke web page at URL http://... . First, enter XXX into text field XXX. Then, press button XXX. Wait until response has been received from web server. Verify that text field XXX now contains the text XXX. The tool should be able to simulate up to several 1000 users, and it should be compatible with web applications using ASP.NET and AJAX.

• Is there a good digraph layout library callable from C++?

  - by Steve314

  The digraphs represent finite automata. Up until now my test program has been writing out dot files for testing. This is pretty good both for regression testing (keep the verified output files in subversion, ask it if there has been a change) and for visualisation. However, there are some problems... Basically, I want something callable from C++ and which plans a layout for my states and transitions but leaves the drawing to me - something that will allow me to draw things however I want and draw on GUI (wxWidgets) windows. I also want a license which will allow commercial use - I don't need that at present, and I may very well release as open source, but I don't want to limit my options ATM. The problems with GraphViz are (1) the warnings about building from source on Windows, (2) all the unnecessary dependencies for rendering and parsing, and (3) the (presumed) lack of a documented API specifically and purely for layout. Basically, I want to be able to specify my states (with bounding rectangle sizes) and transitions, and read out positions for the states and waypoints for each transition, then draw based on those co-ordinates myself. I haven't really figured out how annotations on transitions should be handled, but there should be some kind of provision for specifying bounding-box-sizes for those, associating them with transitions, and reading out positions. Does anyone know of a library that can handle those requirements? I'm not necessarily against implementing something for myself, but in this case I'd rather avoid it if possible.

• How did your team customize Stylecop (and perhaps other tools) for .Net for a good result?

  - by Hamish Grubijan

  Our team is still in a love / hate relationship with it. I am hoping to put an end to the debate by having an internal vote on what rules should be excluded and which rules should be added. Before doing so, I wanted to ask others SO users. To standardize (but not limit) the responses: What is your current StyleCop version? What .Net version do you currently target? Which default rules did you turn off? Which non-default rules have you turned on? Have you coded your own rules? Please describe. Do you have any other StyleCop tricks worth sharing? Do you use Resharper? What version? Is it a good bang for the buck? Do you use any other tools for .Net / C++ which integrate with Visual Studio and aid development? Did you get your money's worth? Anything else you like to add? ... Thank you!

• Good practice to create extension methods that apply to System.Object?

  - by Christian

  Hello, I'm wondering whether I should create extension methods that apply on the object level or whether they should be located at a lower point in the class hierarchy. What I mean is something along the lines of: public static string SafeToString(this Object o) { if (o == null || o is System.DBNull) return ""; else { if (o is string) return (string)o; else return ""; } } public static int SafeToInt(this Object o) { if (o == null || o is System.DBNull) return 0; else { if (o.IsNumeric()) return Convert.ToInt32(o); else return 0; } } //same for double.. etc I wrote those methods since I have to deal a lot with database data (From the OleDbDataReader) that can be null (shouldn't, though) since the underlying database is unfortunately very liberal with columns that may be null. And to make my life a little easier, I came up with those extension methods. What I'd like to know is whether this is good style, acceptable style or bad style. I kinda have my worries about it since it kinda "pollutes" the Object-class. Thank you in advance & Best Regards :) Christian P.S. I didn't tag it as "subjective" intentionally.

• Is there a good way to copy a Gtk widget?

  - by Jake

  Is there a way, using the Gtk library in C, to clone a Gtk button (for instance), and pack it somewhere else in the app. I know you can't pack the same widget twice. And that this code obviously wouldn't work, but shows what happens when I attempt a shallow copy of the button: GtkButton *a = g_object_new(GTK_TYPE_BUTTON, "label", "o_0", NULL); GtkButton *b = g_memdup(b, sizeof *b); gtk_box_pack_start_defaults(GTK_BOX(vbox), GTK_WIDGET(b)); There is surrounding code which creates a vbox and packs it in a window and runs gtk_main(). This will result in these hard to understand error messages: (main:6044): Gtk-CRITICAL **: gtk_widget_hide: assertion `GTK_IS_WIDGET (widget)' failed (main:6044): Gtk-CRITICAL **: gtk_widget_realize: assertion `GTK_WIDGET_ANCHORED (widget) || GTK_IS_INVISIBLE (widget)' failed ** Gtk:ERROR:/build/buildd/gtk+2.0-2.18.3/gtk/gtkwidget.c:8431:gtk_widget_real_map: assertion failed: (GTK_WIDGET_REALIZED (widget)) Along the same lines, if I were to write my own GObject (not necessarily a Gtk widget), is there a good way to write a copy constructor. Im thinking it should be an interface with optional hooks and based mostly on the properties, handling the class's hierarchy in some way. I'd want to do this: GtkButton *b = copyable_copy(COPYABLE(a)); If GtkButton could use a theoretical copyable interface.

• Code smells galore. Can this be a good company?

  - by Paperflyer

  I am currently doing some contract work for a company. Now they want to hire me for real. I have been reading on SO about code smells lately. The thing is, I have worked with some of their code and it smells. Badly. They use incredibly old versions of MSVC (2003), they do not seem to use version control systems, most code is completely undocumented, variable names with more than three letters are a rarity, there is commented out code all over the place, some methods take huge amounts of arguments, UI design is seemingly done by blind people... Yet they seem to be quite successful with what they do and their actual algorithms seem to be pretty sound and rather sophisticated. Since they mostly do DSP stuff, I am willing to ignore the UI side of things, but really these code smells are worrying. What would you think of a company that doesn't seem to value readable code? The people are nice enough and payment would be good. How much would you value code smells in this context? You see, this is my first job and SO got me worried, so I turn to you for suggestions ;-)

• How to write a flexible modular program with good interaction possibilities between modules?

  - by PeterK

  I went through answers on similar topics here on SO but could't find a satisfying answer. Since i know this is a rather large topic, i will try to be more specific. I want to write a program which processes files. The processing is nontrivial, so the best way is to split different phases into standalone modules which then would be used as necessary (since sometimes i will be only interested in the output of module A, sometimes i would need output of five other modules, etc). The thing is, that i need the modules to cooperate, because the output of one might be the input of another. And i need it to be FAST. Moreover i want to avoid doing certain processing more than once (if module A creates some data which then need to be processed by module B and C, i don't want to run module A twice to create the input for modules B,C ). The information the modules need to share would mostly be blocks of binary data and/or offsets into the processed files. The task of the main program would be quite simple - just parse arguments, run required modules (and perhaps give some output, or should this be the task of the modules?). I don't need the modules to be loaded at runtime. It's perfectly fine to have libs with a .h file and recompile the program every time there is a new module or some module is updated. The idea of modules is here mainly because of code readability, maintaining and to be able to have more people working on different modules without the need to have some predefined interface or whatever (on the other hand, some "guidelines" on how to write the modules would be probably required, i know that). We can assume that the file processing is a read-only operation, the original file is not changed. Could someone point me in a good direction on how to do this in C++ ? Any advice is wellcome (links, tutorials, pdf books...).

• Good case for a Null Object Pattern? (Provide some service with a mailservice)

  - by fireeyedboy

  For a website I'm working on, I made an Media Service object that I use in the front end, as well as in the backend (CMS). This Media Service object manipulates media in a local repository (DB); it provides the ability to upload/embed video's and upload images. In other words, website visitors are able to do this in the front end, but administrators of the site are also able to do this in the backend. I'ld like this service to mail the administrators when a visitor has uploaded/embedded a new medium in the frontend, but refrain from mailing them when they upload/embed a medium themself in the backend. So I started wondering whether this is a good case for passing a null object, that mimicks the mail funcionality, to the Media Service in the backend. I thought this might come in handy when they decide the backend needs to have implemented mail functionality as well. In simplified terms I'ld like to do something like this: Frontend: $mediaService = new MediaService( new MediaRepository(), new StandardMailService() ); Backend: $mediaService = new MediaService( new MediaRepository(), new NullMailService() ); How do you feel about this? Does this make sense? Or am I setting myself up for problems down the road?

• How good is the memory mapped Circular Buffer on Wikipedia?

  - by abroun

  I'm trying to implement a circular buffer in C, and have come across this example on Wikipedia. It looks as if it would provide a really nice interface for anyone reading from the buffer, as reads which wrap around from the end to the beginning of the buffer are handled automatically. So all reads are contiguous. However, I'm a bit unsure about using it straight away as I don't really have much experience with memory mapping or virtual memory and I'm not sure that I fully understand what it's doing. What I think I understand is that it's mapping a shared memory file the size of the buffer into memory twice. Then, whenever data is written into the buffer it appears in memory in 2 places at once. This allows all reads to be contiguous. What would be really great is if someone with more experience of POSIX memory mapping could have a quick look at the code and tell me if the underlying mechanism used is really that efficient. Am I right in thinking for example that the file in /dev/shm used for the shared memory always stays in RAM or could it get written to the hard drive (performance hit) at some point? Are there any gotchas I should be aware of? As it stands, I'm probably going to use a simpler method for my current project, but it'd be good to understand this to have it in my toolbox for the future. Thanks in advance for your time.

• Good way to allow people to select a lot of things?

  - by jphenow

  I'm using jQuery, ASP.NET, SQL Server, and the other usual suspects to design a company CRM. After they put in contact info, notes, dates, places and so forth they have to be able to select many different people to be "CC'ed." A group of people will be required to be one either "CC'ed" or "ToDo." The rest of the people can be nothing or "CC" or "ToDo." Currently we have it set up as a huge databind to templates with radio buttons for each option. Looks like shit. Anyone have any suggestions? I'd like to use a template with a datasource and have a good way to retrieve their answers and use them. I'm leaning jQuery direction but like I said I'll need there to be up to 3 possible options for the people. This is going to be all opinion so I'm just looking for options. Just to re-clarify, this concept is similar to email but I don't want them to have to type anything in as it is a set group of names that they're allowed to select from. Looking for quick simple and pretty. somewhere in the range of 120 names.

• [OT a bit] Flex+JEE what is it good for?

  - by Zenzen

  Ok so sorry for being, I guess, a bit off topic but still I think this is the best place to ask. My new semester just started (don't worry I won't ask you to do my homework) and this time we have a rather cool subject about www programming in general where we have to do a web service, web abb - whatever as long as it's "web". Here's the problem though, my team and I want to do it with Flex and JEE but we don't have much experience about what are they actually used for. I mean we know you can do virtually anything with it, but we don't really want to lose time on doing something useless. My first idea was to do a "brainstorming" 3D room/service - a place where people could log in have a video conference, a whiteboard, a place to upload pictures everyone could see, some toolbars for google, youtube etc. plus some other features which would make real-time brainstorming easy when you can't get everyone in one place. But is Flex+JEE really suitable? I mean I'm 99% sure it's doable but is it really worth doing it in Flex+JEE or was the whole purpose of JEE completely different? @EDIT: well this was only one of our ideas obviously. I do know the basics of JSP, Servlets, JPA etc. of course but yeah the main goal of this project is to get some actual experience. The problem is we don't really know is it worth doing something like let's say a social network (something like extended facebook) for gamers (doesn't really matter if it already exists) in JEE or would it only look ridiculous (because PHP or whatever would be a far better choice)? Bottom line is that we are wondering are only large scale applications (for banks etc.) written in JEE or is it good for anything (even the smaller projects)?

• Would an immutable keyword in Java be a good idea?

  - by berry120

  Generally speaking, the more I use immutable objects in Java the more I'm thinking they're a great idea. They've got lots of advantages from automatically being thread-safe to not needing to worry about cloning or copy constructors. This has got me thinking, would an "immutable" keyword go amiss? Obviously there's the disadvantages with adding another reserved word to the language, and I doubt it will actually happen primarily for the above reason - but ignoring that I can't really see many disadvantages. At present great care has to be taken to make sure objects are immutable, and even then a dodgy javadoc comment claiming a component object is immutable when it's in fact not can wreck the whole thing. There's also the argument that even basic objects like string aren't truly immutable because they're easily vunerable to reflection attacks. If we had an immutable keyword the compiler could surely recursively check and give an iron clad guarantee that all instances of a class were immutable, something that can't presently be done. Especially with concurrency becoming more and more used, I personally think it'd be good to add a keyword to this effect. But are there any disadvantages or implementation details I'm missing that makes this a bad idea?

• What's a good way to provide additional decoration/metadata for Python function parameters?

  - by Will Dean

  We're considering using Python (IronPython, but I don't think that's relevant) to provide a sort of 'macro' support for another application, which controls a piece of equipment. We'd like to write fairly simple functions in Python, which take a few arguments - these would be things like times and temperatures and positions. Different functions would take different arguments, and the main application would contain user interface (something like a property grid) which allows the users to provide values for the Python function arguments. So, for example function1 might take a time and a temperature, and function2 might take a position and a couple of times. We'd like to be able to dynamically build the user interface from the Python code. Things which are easy to do are to find a list of functions in a module, and (using inspect.getargspec) to get a list of arguments to each function. However, just a list of argument names is not really enough - ideally we'd like to be able to include some more information about each argument - for instance, it's 'type' (high-level type - time, temperature, etc, not language-level type), and perhaps a 'friendly name' or description. So, the question is, what are good 'pythonic' ways of adding this sort of information to a function. The two possibilities I have thought of are: Use a strict naming convention for arguments, and then infer stuff about them from their names (fetched using getargspec) Invent our own docstring meta-language (could be little more than CSV) and use the docstring for our metadata. Because Python seems pretty popular for building scripting into large apps, I imagine this is a solved problem with some common conventions, but I haven't been able to find them.

• Visual Studio 2008 patching without suppressing database

  - by John

  Hi, I made a program using visual c# which connects to a local .mdf sql database. I've published it using the Publish Wizard, used the files on another computer to install it and it worked fine. However, some bugs were discovered. I've corrected the problems, published it again and tried to patch the program on the 2nd computer. After much trials and errors, fastest way to patch is to overwrite the .application file. Suprisingly, the database was also overwritten. Question is: How do I make new version of the program and install it on the other computer without modifying the database? On developping computer, database appears as a .mdf file which can be copied, but on 2nd computer this file does not exists. Supplementary info: -Developping computer: Vista, using Visual Studio 2008 with Server 2005 -2nd computer: XP using microsoft express server 2005

• Is there unresizable space in latex? Pictures in good looking grid.

  - by drasto

  I've created latex macro to typeset guitar chords diagrams(using picture environment). Now I want to make diagrams of different appear in good looking grid when typeset one next to each other as the picture shows: The picture. (on the picture: Labeled "First" bad layout of diagrams, labeled "Second" correct layout when equal number of diagrams in line) I'm using \hspace to make some skips between diagrams, otherwise they would be too near to each other. As you can see in second case when latex arrange pictures in so that there is same number of them in each line it works. However if there is less pictures in the last line they become "shifted" to the right. I don't want this. I guess is because latex makes the space between diagrams in first line a little longer for the line to exactly fit the page width. How do I tell latex not to resize spaces created by \hspace ? Or is there any other way ? I guess I cannot use tables because I don't know how many diagrams will fit in one line... This is current state of code: \newcommand{\spaceForChord}{1.7cm} \newcommnad{\chordChart}[1]{% %calculate dimensions xdim and ydim according to setings \begin{picture}(xdim, ydim){% %draw the diagram inside defined area }% \hspace*{\spaceForChord}% \hspace*{-\xdim}% }% %end preambule and begin document \begin{document} First:\\* \\* \chordChart{...some arguments for to change diagram look...} \chordChart{...some arguments for to change diagram look...} \chordChart{...some arguments for to change diagram look...} \chordChart{...some arguments for to change diagram look...} \chordChart{...some arguments for to change diagram look...} %...above line is repeated 12 more times to produce result shown at the picture \end{document} Thanks for any help.

• Stopping at my Front-End abilities... good career move?

  - by R. H.

  Just curious about what other front-end and back-end people think, career wise. Here's the details: I'm a 30 yr old mom who is pretty good at front end development - that's my day job at an interactive agency. Don't have the money or time to go back to school or lots of high priced training sessions. I started out as a graphic designer ten years ago or so, then moved into database-backed web stuff, like CMS. I'm great at transforming PSD to a working html and css structure, especially for Wordpress themes. I enjoy this part of the process, probably because it's easy and fun, and as I learn a little more about jQuery and PHP, I can make it even better if I want or need. I'm not sure where I should stop though, as far as my career goes. I don't know that I'll ever get to the point that I'm a great PHP developer or jQuery master. Is it lame to just be a front-end designer/developer? Can that be a successful career all its own? Or, should I obligate myself to learning the harder programming, if I'm capable? Any advice or points any of you may have is appreciated!
