  • Assistance with Lua functions

    - by Josh
    As noted before, I'm relatively new to lua, but again, I learn quick. The last time I got help here, it helped me immensely, and I was able to write a better script. Now I've come to another question that I think will make my life a bit easier. I have no clue what I'm doing with functions, but I'm hoping there is a way to do what I want to do here. Below, you'll see an example of code I have to do to strip down some unneeded elements. Yeah, I realize it's not efficient in the least, so if anyone else has a better idea of how to make it much more efficient, I'm all ears. What I would like to do is create a function with it so that I can strip down whatever variable with a simple call of it (like stripdown(winds)). I appreciate any help that is offered, and any lessons given. Thanks! winds = string.gsub(winds,"%b<>","") winds = string.gsub(winds,"%c"," ") winds = string.gsub(winds," "," ") winds = string.gsub(winds," "," ") winds = string.gsub(winds,"^%s*(.-)%s*$", "%1)") winds = string.gsub(winds,"&nbsp;","") winds = string.gsub(winds,"/ ", "(") Josh

  • How do you move an admin menu item in Magento

    - by Josh Pennington
    I currently have an extension that I created and it currently sits inside of its own top level menu. I would like to move it so that the item would appear inside of the Customers menu. Does anyone know how to do this? It looks like this is handled inside the extensions config.xml file. The code that I have for it right now is as follows: <menu> <testimonials module="testimonials"> <title>Testimonials</title> <sort_order>71</sort_order> <children> <items module="testimonials"> <title>Manage Items</title> <sort_order>0</sort_order> <action>testimonials/adminhtml_testimonials</action> </items> </children> </testimonials> </menu> I tried changing the title element to Customers and it just created a duplicate Customers menu. Does anyone have any ideas? Thanks Josh Pennington

  • The Buzz at the JavaOne Bookstore

    - by Janice J. Heiss
    I found my way to the JavaOne bookstore, a hub of activity. Who says brick and mortar bookstores are dead? I asked what was hot and got two answers: Hadoop in Practice by Alex Holmes was doing well. And Scala for the Impatient by noted Java Champion Cay Horstmann also seemed to be a fast seller. Hadoop in PracticeHadoop is a framework that organizes large clusters of computers around a problem. It is touted as especially effective for large amounts of data, and is use such companies as  Facebook, Yahoo, Apple, eBay and LinkedIn. Hadoop in Practice collects nearly 100 Hadoop examples and presents them in a problem/solution format with step by step explanations of solutions and designs. It’s very much a participatory book intended to make developers more at home with Hadoop.The author, Alex Holmes, is a senior software engineer with more than 15 years of experience developing large-scale distributed Java systems. For the last four years, he has gained expertise in Hadoop solving Big Data problems across a number of projects. He has presented at JavaOne and Jazoon and is currently a technical lead at VeriSign.At this year’s JavaOne, he is presenting a session with VeriSign colleague, Karthik Shyamsunder called “Java: A Perfect Platform for Data Science” where they will explain how the Java platform has emerged as a perfect platform for practicing data science, and also talk about such technologies as Hadoop, Hive, Pig, HBase, Cassandra, and Mahout. Scala for the ImpatientSan Jose State University computer science professor and Java Champion Cay Horstmann is the principal author of the highly regarded Core Java. Scala for the Impatient is a basic, practical introduction to Scala for experienced programmers. Horstmann has a presentation summarizing the themes of his book on at his website. On the final page he offers an enticing summary of his conclusions:* Widespread dissatisfaction with Java + XML + IDEs               --Don't make me eat Elephant again * A separate language for every problem domain is not efficient               --It takes time to master the idioms* ”JavaScript Everywhere” isn't going to scale* Trend is towards languages with more expressive power, less boilerplate* Will Scala be the “one ring to rule them”?* Maybe              --If it succeeds in industry             --If student-friendly subsets and tools are created The popularity of both books echoed comments by IBM Distinguished Engineer Jason McGee who closed his part of the Sunday JavaOne keynote by pointing out that the use of Java in complex applications is increasingly being augmented by a host of other languages with strong communities around them – JavaScript, JRuby, Scala, Python and so forth. Java developers increasingly must know the strengths and weaknesses of such languages going forward.

  • SQL: How to select rows from a table while ignoring the duplicate field values?

    - by Maxxon
    How to select rows from a table while ignoring the duplicate field values? Here is an example: id user_id message 1 Adam "Adam is here." 2 Peter "Hi there this is Peter." 3 Peter "I am getting sick." 4 Josh "Oh, snap. I'm on a boat!" 5 Tom "This show is great." 6 Laura "Textmate rocks." What i want to achive is to select the recently active users from my db. Let's say i want to select the 5 recently active users. The problem is, that the following script selects Peter twice. mysql_query("SELECT * FROM messages ORDER BY id DESC LIMIT 5 "); What i want is to skip the row when it gets again to Peter, and select the next result, in our case Adam. So i don't want to show my visitors that the recently active users were Laura, Tom, Josh, Peter, and Peter again. That does not make any sense, instead i want to show them this way: Laura, Tom, Josh, Peter, (skipping Peter) and Adam. Is there an SQL command i can use for this problem?

  • Web versus desktop development - is web development worse?

    - by Josh Kelley
    As a longtime desktop developer looking at doing our first large-scale web application, what are the pros and cons of doing web development? Is developing a web application much worse than developing a desktop app? E.g., is it more tedious or annoying? Is the time to market much worse? Is the web platform excessively limiting? If the answer to any of these is yes, then why? (And how does developing a Flash or Silverlight app compare?)

  • Best practices for team workflow with RoR/Github for designer + coder?

    - by Josh
    My friend and I have started to try to collaborate on some projects. For background, I come from a PHP/Wordpress/Drupal coding background, but recently I've become more experienced with the RoR framework, while he is more experienced as an HTML/CSS designer, working with PHP and WordPress. We're both relatively new to RoR I think, and so we're trying to figure out our collaborative workflow, but we have no idea where to start. For instance, we were trying to figure out how he could do some minor edits to the CSS file without having to do a full RoR deploy on his box. We still haven't figured out a solution, so I think it's best if we start to set some sort of workflow based on best practices. I was wondering if you guys have any insight or links to articles/case studies regarding this topic?

  • How can I use Windows Workflow for validation of a Silverlight application?

    - by Josh C.
    I want to use Windows Workflow to provide a validation service. The validation that will be provided may have multiple tiers with chaining and redirecting to other stages of validation. The application that will generate the data for validation is a Silverlight app. I imagine the validation will take longer than the blink of an eye, so I don't want to tie the user up. Instead, I would like the user to submit the current data for validation. If the validation happens quickly, the service will perform an asynchronous callback to the app. The viewmodel that made the call would receive the validation output and post into the view. If the validation takes a long time, the user can move forward in the Silverlight app, disregarding the potential output of the validation. The viewmodel that made the call would be gone. I expect there would be another viewmodel that would contain the current validation output in its model. The validation value would change causing the user to get a notification in smaller notifcation area. I can see how the current view's viewmodel would call the validation through the viewmodel that is containing the validation output, but I am concerned that the service call will timeout. Also, I think the user may have already changed the values from the original validation, invalidating the feedback. I am sure asynchronous validation is a problem solved many times over, I am looking to glean from your experience in solving this kind of problem. Is this the right approach to the problem, or is there a better way to approach this?

  • Handling Coding Standards at Work (I'm not the boss)

    - by Josh Johnson
    I work on a small team, around 10 devs. We have no coding standards at all. There are certain things that have become the norm but some ways of doing things are completely disparate. My big one is indentation. Some use tabs, some use spaces, some use a different number of spaces, which creates a huge problem. I often end up with conflicts when I merge because someone used their IDE to auto format and they use a different character to indent than I do. I don't care which we use I just want us all to use the same one. Or else I'll open a file and some lines have curly brackets on the same line as the condition while others have them on the next line. Again, I don't mind which one so long as they are all the same. I've brought up the issue of standards to my direct manager, one on one and in group meetings, and he is not overly concerned about it (there are several others who share the same view as myself). I brought up my specific concern about indentation characters and he thought a better solution would be to, "create some kind of script that could convert all that when we push/pull from the repo." I suspect that he doesn't want to change and this solution seems overly complicated and prone to maintenance issues down the road (also, this addresses only one manifestation of a larger issue). Have any of you run into a similar situation at work? If so, how did you handle it? What would be some good points to help sell my boss on standards? Would starting a grass roots movement to create coding standards, among those of us who are interested, be a good idea? Am I being too particular, should I just let it go? Thank you all for your time. Note: Thanks everyone for the great feedback so far! To be clear, I don't want to dictate One Style To Rule Them All. I'm willing to concede my preferred way of doing something in favor of what suits everyone the best. I want consistency and I want this to be a democracy. I want it to be a group decision that everyone agrees on. True, not everyone will get their way, but I'm hoping that everyone will be mature enough to compromise for the betterment of the group. Note 2: Some people are getting caught up in the two examples I gave above. I'm more after the heart of the matter. It manifests itself with many examples: naming conventions, huge functions that should be broken up, should something go in a util or service, should something be a constant or injected, should we all use different versions of a dependency or the same, should an interface be used for this case, how should unit tests be set up, what should be unit tested, (Java specific) should we use annotations or external config. I could go on.

  • How to manage security cameras in Ubuntu?

    - by Josh
    I am setting up a server of sorts and chose ubuntu for the OS as my dad has it on a few computers. I am unimpressed with Windows or MAC due to all the add-ons and complexity of it when all I want is something simple. The system will have 3 purposes, storing my wife's photography work (she is a professional photographer) storing music for quick access to our entertainment system (will be running the system through the tv in our living room and thus through our surround sound) and will also serve as a DVR unit for a home security system I am going to put together. My question is what sort of software options are there for the Ubuntu system as far as a DVR with frame by frame playback. It does not need to be fancy but of course a variety of options are a nice touch.

  • Would knowing Python help with creating iPhone applications?

    - by Josh
    Here is what the apple site says: With Snow Leopard, Mac OS X makes it easy to use scripting languages as full application development tools. Snow Leopard ships with support for the RubyCocoa Bridge and the PyObjC bridge. These two bridges give developers access not only to system APIs, but to Cocoa frameworks such as AppKit and Core Data, enabling you to build fully native Mac OS X applications in Ruby or Python. The RubyCocoa and PyObjC bridges allow you to freely mix code written in Objective-C with code written in the scripting language. You can quickly build prototypes and then optimise by implementing performance-critical pieces in Objective-C. How could Python help in this case?

  • Managing JS and CSS for a static HTML web application

    - by Josh Kelley
    I'm working on a smallish web application that uses a little bit of static HTML and relies on JavaScript to load the application data as JSON and dynamically create the web page elements from that. First question: Is this a fundamentally bad idea? I'm unclear on how many web sites and web applications completely dispense with server-side generation of HTML. (There are obvious disadvantages of JS-only web apps in the areas of graceful degradation / progressive enhancement and being search engine friendly, but I don't believe that these are an issue for this particular app.) Second question: What's the best way to manage the static HTML, JS, and CSS? For my "development build," I'd like non-minified third-party code, multiple JS and CSS files for easier organization, etc. For the "release build," everything should be minified, concatenated together, etc. If I was doing server-side generation of HTML, it'd be easy to have my web framework generate different development versus release HTML that includes multiple verbose versus concatenated minified code. But given that I'm only doing any static HTML, what's the best way to manage this? (I realize I could hack something together with ERB or Perl, but I'm wondering if there are any standard solutions.) In particular, since I'm not doing any server-side HTML generation, is there an easy, semi-standard way of setting up my static HTML so that it contains code like <script src="js/vendors/jquery.js"></script> <script src="js/class_a.js"></script> <script src="js/class_b.js"></script> <script src="js/main.js"></script> at development time and <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script> <script src="js/entire_app.min.js"></script> for release?

  • Optimizing MySQL -

    - by Josh
    I've been researching how to optimize MySQL a bit, but I still have a few questions. MySQL Primer Results http://pastie.org/private/lzjukl8wacxfjbjhge6vw Based on this, the first problem seems to be that the max_connections limit is too low. I had a similar problem with Apache initially, the max connection limit was set to 100, and the web server would frequently lock up and take an excruciatingly long time to deliver pages. Raising the connection limit to 512 fixed this issue, and I read that raising the connection limit on MySQL to match this was considered good practice. Being that MySQL has actually been "locking up" recently as well (connections have been refused entirely for a few minutes at a time at random intervals) I'm assuming this is the main cause of the issue. However, as far as table cache goes, I'm not sure what I should set this as. I've read that setting this too high can hinder performance further, so should I raise this to right around 551, 560, 600, or do something else? Lastly, as far as raising the join_buffer_size value goes, this doesn't even seem to be included in Debian's my.cnf file by default. Assuming there's not much I can do about adding indexes, should I look into raising this? Any suggested values? Any suggestions in general here would be appreciated as well. Edit: Here's the number of open tables the MySQL server is reporting. I believe this value is related to my question (Opened_tables: 22574)

  • Typical Method Of Building Puzzle Levels

    - by Josh Kahane
    Hi I am designing a puzzle game for the iphone and was wondering as most puzzle games consist of the player progressing through multiple levels. You see for example Angry Birds has over 100 levels. Once the basis of the game is made, how do developers typically go about building their levels? Do they generally build them from scratch each one more or less, or work of their own template or have some other method which they use to tailor these levels? I imagine building so many levels is a long process, certainly if building each one individually. Do they do this, or have a method which speeds it up once they have their basis? Thanks.

  • Sitronix ST9RM01 touchscreen not working

    - by Josh Kelley
    I have a Sitronix ST9RM01 touchscreen that I'm trying to get working with Ubuntu 12.04. The touchscreen is apparently recognized by Linux and X - the hid_multitouch module is loaded, and lsinput and xinput both list the touchscreen as an input device - but touching the screen does absolutely nothing, and xinput test shows no events. The same touchscreen works just fine in Windows. How can I troubleshoot from here? Any suggestions?

  • Aggregating Excel cell contents that match a label [migrated]

    - by Josh
    I'm sure this isn't a terribly difficult thing, but it's not the type of question that easily lends itself to internet searches. I've been assigned a project for work involving a complex spreadsheet. I've done the usual =SUM and other basic Excel formulas, and I've got enough coding background that I'm able to at least fudge my way through VBA, but I'm not certain how to proceed with one part of the task. Simple version: On Sheet 1 I have a list of people (one on each row, person's name in column A), on sheet 2 I have a list of groups (one on each row, group name in column A). Each name in Sheet 1 has its own row, and I have a "Data Validation" dropdown menu where you choose the group each person belongs to. That dropdown is sourced from Sheet 2, where each group has a row. So essentially the data validation source for Sheet 1's "Group" column is just "=Sheet2!$a1:a100" or whatever. The problem is this: I want each group row in Sheet 2 to have a formula which results in a list of all the users which have been assigned to that group on Sheet 1. What I mean is something the equivalent of "select * from PeopleTab where GROUP = ThisGroup". The resulting cell would just stick the names together like "Bob Smith, Joe Jones, Sally Sanderson" I've been Googling for hours but I can't think of a way to phrase my search query to get the results I want. Here's an example of desired result (Dash-delimited. Can't find a way to make it look nice, table tags don't seem to work here): (Sheet 1) Bob Smith - Group 1 (selected from dropdown) Joe Jones - Group 2 (selected from dropdown) Sally Sanderson - Group 1 (selected from dropdown) (Sheet 2) Group 1 - Bob Smith, Sally Sanderson (result of formula) Group 2 - Joe Jones (result of formula) What formula (or even what function) do I use on that second column of sheet 2 to make a flat list out of the members of that group?

  • Suspending my laptop breaks ethernet over firewire, are there commands which can fix it?

    - by Josh
    As mentioned in this question I am using a firewire cable to provide a private network between my laptop and my desktop, because it makes using the screen sharing program synergy much nicer than using WIFI. However when I leave my office for the day and I suspend my laptop, when I return the next day, the desktop and the laptop cannot communicate over firewire anymore. The firewire0 device still has an IP address. but when I try and ping the desktop I get no route to host I'm using kernel 2.6.35-24-generic #42-Ubuntu SMP x86_64 on Ubuntu 10.10.

  • Why is the console hanging randomly?

    - by Josh M.
    Ubuntu 10.10 Server x64 installed as Virtual Box VM. Fresh install plus postgresql and tomcat6 installed via aptitude. Rebooted the server and now when I run some command the console hangs. For instance, I run "sudo shutdown now" and then nothing happens but I am not returned to the prompt. I hit CTRL+C and nothing happens except ^C appears on the following line. I can type whatever and it will show up inline. I switch to tty2 and try to login and I only get as far as [username][enter] and that console hangs. One other thing - after "sudo reboot" the console appears to hang (just like above) when shutting down tomcat6. Any idea what's going on or what I should check? Thanks!

  • How to manage an issue tracker's backlog

    - by Josh Kelley
    We've been dutifully using Trac for several years now, and our "active tickets" list has grown to almost 200 items. These include bugs that are too low priority and too complicated to fix for now, feature requests that have been deferred, issues that have never really generated complaints but everyone agrees ought to be fixed someday, planned code refactorings and other design infelicities that we don't want to lose track of, etc. As a result, with almost 200 of these issues, the list is almost overwhelming; it's no longer useful as a source of what needs to be worked on right now. What's the best way to keep track of issues of this sort? Part of the problem is that some of these issues are such a low priority that they may never get done. I hate to lose track of these items (similar to not wanting to throw something out of my house in case I might need it someday); do I need to throw them out regardless (by marking them as wontfix) and assume I can find them in the future if I ever do need them?

  • Using a SMTP Service for email

    - by Josh S.
    This may be a horribly obvious question, but I'm learning and just need someone to confirm it for me. I putting together a private social network that needs to email their members (through the social network software, Elgg) regularly. I'm hosting it on a shared HostGator plan (because they won't receive much traffic) and they'll email 10-1000 emails a few times a week. HostGator restricts you to 500 per hour. I'm also worried about deliverability. I've been searching up and down about how to throttle the emails so it will all send reliably... but then I came across the idea of an outside SMTP relay service. Would using an SMTP service resolve this issue? If so, any opinions on quality SMTP services?

  • Get Your Enterprise Working With Oracle On Track Communication 1.0

    - by Josh Lannin
    The On Track Development team is very pleased to announce that today On Track is available for our customers to download and evaluate.  To learn more about what On Track does start with our whitepaper and datasheet.   If you are a developer, take a look at our documentation and samples posted to our OTN page. For this first blog post, I’ll be speaking to several notable points about our product. Graceful Escalation via Conversations: On Track addresses the “Collaboration Problem” through a single guiding principle – graceful escalation – within the construct of a Conversation. In On Track, collaboration is based on a context (called a “Conversation”) that gracefully escalates in form, structure, and content, as dictated by the particular needs of a given collaboration.  Within that context, On Track provides a rich set of tools to choose from.  These tools provide for communication, coordination, content management, organization, decision making, and analysis -- all essential aspects of collaboration, but not all of them are essential all of the time.  Every collaborative interaction will evolve differently.  Some will evolve to represent work spreading over the course of years and involving a large, distributed team, while others may involve few people and not evolve at all.  Regardless, all collaborative contexts are built from the same parts, utilize the same concepts, and start the same way.  The principle of graceful escalation is that you only use the tools and structure you need; so you only incur the complexity you need. Purposeful Collaboration: Through application integration, On Track Conversations bring enterprise application users the communication and collaboration capabilities required to complete business process.  By association with specific processes or business objects conversations extend the possible interactions and broaden participation to internal or external non-application users and provide a sophisticated interaction experience, all the while enhancing the data set within the owning application.  Purposeful collaboration not only needs to happen in the context of applications, it must support a full range of real-time and long-running interactions to provide the greatest value. Multi Client, Multi Modal: This On Track 1.0 product release includes the same day availability of  multiple clients, including iPhone and iPad applications which are now available on the Apple Store, a fully capable and accessible Outlook Add-In, along with our browser web client.  With each client we have sought to leverage the strengths of each unique device- our iPhone client supports picture and voice posts, the iPad is optimized for meeting room situations and document viewing, and our Outlook add-in allows you to take emails in context and bring them into On Track.  In addition to supporting a diverse array of clients, On Track provides a unified multi modal experience support starting with basic messages moving through to integrated documents with live annotations, snapshots, application sharing, and voice. Next Generation Web Architecture: We believe On Track will help move the bar higher for what users can expect from all web applications, most notably ones that involve real-time activity.  On Track is built from the ground up with an innovative, real-time architecture that leverages the extensive push capabilities of our server.  Whether you are receiving a new message, viewing where crowds of people are collaborating, or doing live annotation on a document with a set of people, that information comes to you immediately without refreshes or moving back and forth between pages.  We’ve leveraged this core architecture across the product experience and raised the user experience bar for this type of application.  As well these capabilities are based on open standards and protocols, and are fully extensible by anyone- enabling sophisticated integrations to be created with a wide variety of both legacy and next-generation applications. Agile Product Development: As a product team we operate using continuous feedback and modified agile development methodologies.  We have thousands of active internal Oracle users who have helped pilot our product for critical business functions, and the On Track product development team uses our product as our primary vehicle for all our collaboration.  Additionally we been working with early access customers who are adopting our technology and providing us valuable feedback - which our process has rapidly realized in improvements to our software.  On Track agility extends to our server as well, which is built to scale, and is very simple to install and configure.

  • ecryptfs - decrypt and mount at boot with USB key

    - by Josh McGee
    I have a system running Ubuntu Server as a testbed for some services that I want to get familiar with. I decided to let the installation procedure set up encryption. I knew all along that I would have to decrypt it with the passphrase in order to get the system booted, but I assumed it wouldn't matter since it will only boot once or twice a month. However, my brother has informed me that he is a victim of power outages at the residence where this server is located. This means we have to explain to his girlfriend how to turn on the computer, attach a keyboard, connect a monitor (she just can't understand that she can type to the computer without a display, so whatever) and input the passphrase for us, while we are at work. I have arrived at the conclusion that I should just put together a USB key that can be plugged in before powering on the computer, to avoid all the trouble. Is this possible with ecryptfs? Is there a tutorial or simple list of instructions available so that I can knock this out and focus back on the stuff I care about? EDIT: I am aware that this is possible with LUKS and dm-crypt, but unfortunately the magical encryption that Ubuntu hands you during the installation is only ecryptfs so my question is specific to that.

  • Editing service for blogger with terrible English grammar

    - by Josh Moore
    I would like to write a technical blog. However, the biggest things holding me back is my poor spelling, punctuation, and grammar (I have all these problems even though I am a native English speaker). I am thinking about using a professional editing/proofreading service to fix my blog posts before I post them. However, given the content will be technical in nature (some articles will get into details of programming) and I would like to write them in markdown, I am not sure if the general online services will be a good fit. Can you recommend a editor (or company) that you like that can provide this service?
