• User Permissions: Daemon and User

  - by Eddie Parker

  Hello: I often run into this issue on Linux, and I'd love to know the proper way of solving it. Say I have a daemon running. In my example, I'll use LigHTTPD, a webserver. Some software, like Wordpress, enjoys having read/write access to files for updating applications via a web interface, which I think is quite handy. At the same time, I enjoy being able to hack on my files using vim, using my local user account, 'eddie'. Herein lies the rub. Either I chown everything to lighttpd or eddie and a shared group between them both, and chmod it 660, or perpetually sudo to edit the damned things. The former isn't a bad solution, until I create a new file in which case I have to remember to chmod it appropriately, or create some hack like a cron job that chmods for me. Is there an easier way of doing this? Have I overlooked something? Cheers, -e-

• Securing data sent to an unencrypted WiFi AP

  - by David Parunakian

  The business plan of a project I'm involved in assumes selling certain WiFi-enabled devices to end users. All these devices originally have an unencrypted connection and a standard SSID. The problem is that although the user can connect to it and set both a new SSID and a WPA passphrase, these are being sent to the AP in plain text and thus can be intercepted by anyone nearby with a sniffer. What's the best solution to this problem, and why? Initially set up an encrypted wireless network at the device and supply the user with a printed passphrase Buy an SSL certificate for the AP's default IP address or local domain name (the APs aren't supposed to work as a router and have a captive portal & dnsmasq installed, so all of them can pretend to be myunit.example.com, as far as I understand) Something different Thank you.

• How can I dual boot a UEFI OS and a legacy boot OS, or convert stock Windows 8 to BIOS?

  - by The Great Widi

  I have a computer (HP Pavilion g6-2342dx) which came with Windows 8, and thus the new UEFI boot system. I would like to install a few OS's which are not EFI compatible, and Arch GNU/Linux with BIOS mode. However, I would not like to completely wipe all my files to set to legacy. My preferred options would be to: 1. Multiboot legacy OS alongside my EFI os 2. Convert Windows 8 and Ubuntu to legacy without reformatting or switching to MSDOS part table. If anyone could suggest a solution or a method, your help would be appreciated! Thanks!

• Windows activation on a Virtual Machine (Physical->VM)

  - by Daisetsu

  I backed up a number of laptops to virtual machines before they are to be re-purposed, in case I need the data at some later time. While the Physical to VM processes worked fine I am encountering issues on some of the VMs. When I boot them I get an error message saying I MUST activate windows in order to login. This is expected because the hardware changed (from physical hardware to virtualized hardware). I click the OK button and expect to be prompted with ways to activate, windows sits there for quite a while then tells me that "Windows has already been activated". I click OK at that message and get take back to the beginning where I am asked to activate Windows. I have done some fairly intensive googling but haven't been able to find a real solution. EDIT: The laptops with the issues are 2 Sony Vaios, I believe that they have the OEM version of the OS originally installed by the factory.

• Windows XP stay logged in

  - by VEC

  Is there a way to make Windows XP stay logged in even after the user logs off? Right now the PCs log in at start up and we're using WinOFF to shut down the computer after X minutes of inactivity. The problem is that WinOFF does not work when the user logs off and stays in the "Select user login" screen. I'm thinking a possible solution would be to make the computer log back in as the default user after Y minutes of inactivity. How can I make it so that Windows XP logs in automatically after the user logs off?

• Can't connect to database in dreamweaver

  - by ReallyGoodPie

  I used to have this error in Dreamweaver CS6 and I would simply place the _mmServerScripts folder into the root of my local website. Every time I go to select a database it get this error: I have been searching the net for at least 2 hours now trying to find a solution. It is becoming quite annoying. Everything is working perfectly fine. All the server settings are 100% correct. I have seen various videos on youtube where the user is using a mac and they simply go and grab the _mmServerScripts folder from their dreamweaver folder but I can't seem to locate this. I used to simply use _mmServerScripts folder from dreamweaver CS5.5 and it would end up working perfectly. I don't know how to fix the issue so does anybody have any idea?

• Can't create new folder from anywhere in Windows 7

  - by ymasood

  I have this problem on two of my new laptops and can't seem to find a decent workable solution elsewhere in forum land. The problem is that on my Windows 7 Professional machines the right mouse button doesn't show the New Folder option and elsewhere as well (via Explorer) I'm unable to create new folders. I'll be happy to get this tiny problem resolved and declare that Windows 7 is almost perfect! Thanks to all of you in advance for your contribution! PS: None of the Vista solutions seem to work here!

• SPARC64 VII+ Processor Core License Factor Reduced by 33%

  - by john.shell

  The Oracle processor core license factor has been a popular topic the last few months.  For those partners new to Oracle software licensing, the processor core license factor determines the number licensed CPUs that are required when running Oracle software (those charged on a per-CPU basis) on multi-core processors.My last entry talked about the core factor reduction for our T3 processor.  The core license factor for our newly announced SPARC64 VII+ processor is 0.5, which is a 33% reduction from the 0.75 rate used with our SPARC64 VI and VII processors.What does this mean for our partners?  Increased opportunity.  This change, similar to our T3-based systems, means that our hardware is the preferred platform for Oracle software. Still a little dizzy on the breadth of Oracle's software offering?  Do a simple scan of Oracle's software price lists. Consider this your target market.This change allows you to focus on total solution price or price/performance, not server prices or per core performance (a standard IBM sales tactic). That's the offensive side of the game.  Don't forget your defense.  One of the biggest customer benefits around the M-Series is investment protection.  The combination of a simple processor/board upgrade, along with a reduction in processor core license factor, makes upgrading one of the best financial moves for our customers.    One reminder.  The update to the processor core license factor only applies to the new VII+ processor - NOT the SPARC64 VI or VII processors.  You can find the official table here.

• Should I include HTML markup in my JSON response?

  - by Mike M. Lin

  In an e-commerce site, when adding an item to a cart, I'd like to show a popup window with the options you can choose. Imagine you're ordering an iPod Shuffle and now you have to choose the color and text to engrave. I'd like the window to be modal, so I'm using a lightbox populated by an Ajax call. Now I have two options: Option 1: Send only the data, and generate the HTML markup using JavaScript What's nice about this is that it trims down the Ajax request to the bear minimum and doesn't mix the data with the markup. What's not so great about this is that now I need to use JavaScript to do my rendering, instead of having a template engine on the server-side do it. I might be able to clean up the approach a bit by using a client-side templating solution. Option 2: Send the HTML markup What's good about this is that I can have the same server-side templating engine I'm using for the rest of my rendering tasks (Django), do the rendering of the lightbox. JavaScript is only used to insert the HTML fragment into the page. So it clearly leaves the rendering to the rendering engine. Makes sense to me. But I don't feel comfortable mixing data and markup in an Ajax call for some reason. I'm not sure what makes me feel uneasy about it. I mean, it's the same way every web page is served up -- data plus markup -- right?

• Tomcat fails to start, no logs or error provided

  - by Alex Kuhl

  I have a Centos5 box running tomcat5 (a version before 5.5, there's no bin/version.sh script). When attempting to start tomcat, whether through init.d or service, I get the FAILED message with no other information provided. The date on catalina.out changes but it has no contents and is 0 bytes. logging.conf has not been edited and everything is marked as FINE detail. Has anyone experienced this and know of a solution? Or, failing that, how can I get some log/error info from tomcat to try to pinpoint the issue?

• Software Engineering Practices &ndash; Different Projects should have different maturity levels

  - by Dylan Smith

  I’ve had a lot of discussions at the office lately about the drastically different sets of software engineering practices used on our various projects, if what we are doing is appropriate, and what factors should you be considering when determining what practices are most appropriate in a given context. I wanted to write up my thoughts in a little more detail on this subject, so here we go: If you compare any two software projects (specifically comparing their codebases) you’ll often see very different levels of maturity in the software engineering practices employed. By software engineering practices, I’m specifically referring to the quality of the code and the amount of technical debt present in the project. Things such as Test Driven Development, Domain Driven Design, Behavior Driven Development, proper adherence to the SOLID principles, etc. are all practices that you would expect at the mature end of the spectrum. At the other end of the spectrum would be the quick-and-dirty solutions that are done using something like an Access Database, Excel Spreadsheet, or maybe some quick “drag-and-drop coding”. For this blog post I’m going to refer to this as the Software Engineering Maturity Spectrum (SEMS). I believe there is a time and a place for projects at every part of that SEMS. The risks and costs associated with under-engineering solutions have been written about a million times over so I won’t bother going into them again here, but there are also (unnecessary) costs with over-engineering a solution. Sometimes putting multiple layers, and IoC containers, and abstracting out the persistence, etc is complete overkill if a one-time use Access database could solve the problem perfectly well. A lot of software developers I talk to seem to automatically jump to the very right-hand side of this SEMS in everything they do. A common rationalization I hear is that it may seem like a small trivial application today, but these things always grow and stick around for many years, then you’re stuck maintaining a big ball of mud. I think this is a cop-out. Sure you can’t always anticipate how an application will be used or grow over its lifetime (can you ever??), but that doesn’t mean you can’t manage it and evolve the underlying software architecture as necessary (even if that means having to toss the code out and re-write it at some point…maybe even multiple times). My thoughts are that we should be making a conscious decision around the start of each project approximately where on the SEMS we want the project to exist. I believe this decision should be based on 3 factors: 1. Importance - How important to the business is this application? What is the impact if the application were to suddenly stop working? 2. Complexity - How complex is the application functionality? 3. Life-Expectancy - How long is this application expected to be in use? Is this a one-time use application, does it fill a short-term need, or is it more strategic and is expected to be in-use for many years to come? Of course this isn’t an exact science. You can’t say that Project X should be at the 73% mark on the SEMS and expect that to be helpful. My point is not that you need to precisely figure out what point on the SEMS the project should be at then translate that into some prescriptive set of practices and techniques you should be using. Rather my point is that we need to be aware that there is a spectrum, and that not everything is going to be (or should be) at the edges of that spectrum, indeed a large number of projects should probably fall somewhere within the middle; and different projects should adopt a different level of software engineering practices and maturity levels based on the needs of that project. To give an example of this way of thinking from my day job: Every couple of years my company plans and hosts a large event where ~400 of our customers all fly in to one location for a multi-day event with various activities. We have some staff whose job it is to organize the logistics of this event, which includes tracking which flights everybody is booked on, arranging for transportation to/from airports, arranging for hotel rooms, name tags, etc The last time we arranged this event all these various pieces of data were tracked in separate spreadsheets and reconciliation and cross-referencing of all the data was literally done by hand using printed copies of the spreadsheets and several people sitting around a table going down each list row by row. Obviously there is some room for improvement in how we are using software to manage the event’s logistics. The next time this event occurs we plan to provide the event planning staff with a more intelligent tool (either an Excel spreadsheet or probably an Access database) that can track all the information in one location and make sure that the various pieces of data are properly linked together (so for example if a person cancels you only need to delete them from one place, and not a dozen separate lists). This solution would fall at or near the very left end of the SEMS meaning that we will just quickly create something with very little attention paid to using mature software engineering practices. If we examine this project against the 3 criteria I listed above for determining it’s place within the SEMS we can see why: Importance – If this application were to stop working the business doesn’t grind to a halt, revenue doesn’t stop, and in fact our customers wouldn’t even notice since it isn’t a customer facing application. The impact would simply be more work for our event planning staff as they revert back to the previous way of doing things (assuming we don’t have any data loss). Complexity – The use cases for this project are pretty straightforward. It simply needs to manage several lists of data, and link them together appropriately. Precisely the task that access (and/or Excel) can do with minimal custom development required. Life-Expectancy – For this specific project we’re only planning to create something to be used for the one event (we only hold these events every 2 years). If it works well this may change (see below). Let’s assume we hack something out quickly and it works great when we plan the next event. We may decide that we want to make some tweaks to the tool and adopt it for planning all future events of this nature. In that case we should examine where the current application is on the SEMS, and make a conscious decision whether something needs to be done to move it further to the right based on the new objectives and goals for this application. This may mean scrapping the access database and re-writing it as an actual web or windows application. In this case, the life-expectancy changed, but let’s assume the importance and complexity didn’t change all that much. We can still probably get away with not adopting a lot of the so-called “best practices”. For example, we can probably still use some of the RAD tooling available and might have an Autonomous View style design that connects directly to the database and binds to typed datasets (we might even choose to simply leave it as an access database and continue using it; this is a decision that needs to be made on a case-by-case basis). At Anvil Digital we have aspirations to become a primarily product-based company. So let’s say we use this tool to plan a handful of events internally, and everybody loves it. Maybe a couple years down the road we decide we want to package the tool up and sell it as a product to some of our customers. In this case the project objectives/goals change quite drastically. Now the tool becomes a source of revenue, and the impact of it suddenly stopping working is significantly less acceptable. Also as we hold focus groups, and gather feedback from customers and potential customers there’s a pretty good chance the feature-set and complexity will have to grow considerably from when we were using it only internally for planning a small handful of events for one company. In this fictional scenario I would expect the target on the SEMS to jump to the far right. Depending on how we implemented the previous release we may be able to refactor and evolve the existing codebase to introduce a more layered architecture, a robust set of automated tests, introduce a proper ORM and IoC container, etc. More likely in this example the jump along the SEMS would be so large we’d probably end up scrapping the current code and re-writing. Although, if it was a slow phased roll-out to only a handful of customers, where we collected feedback, made some tweaks, and then rolled out to a couple more customers, we may be able to slowly refactor and evolve the code over time rather than tossing it out and starting from scratch. The key point I’m trying to get across is not that you should be throwing out your code and starting from scratch all the time. But rather that you should be aware of when and how the context and objectives around a project changes and periodically re-assess where the project currently falls on the SEMS and whether that needs to be adjusted based on changing needs. Note: There is also the idea of “spectrum decay”. Since our industry is rapidly evolving, what we currently accept as mature software engineering practices (the right end of the SEMS) probably won’t be the same 3 years from now. If you have a project that you were to assess at somewhere around the 80% mark on the SEMS today, but don’t touch the code for 3 years and come back and re-assess its position, it will almost certainly have changed since the right end of the SEMS will have moved farther out (maybe the project is now only around 60% due to decay). Developer Skills Another important aspect to this whole discussion is around the skill sets of your architects and lead developers. When talking about the progression of a developers skills from junior->intermediate->senior->… they generally start by only being able to write code that belongs on the left side of the SEMS and as they gain more knowledge and skill they become capable of working at a higher and higher level along the SEMS. We all realize that the learning never stops, but eventually you’ll get to the point where you can comfortably develop at the right-end of the SEMS (the exact practices and techniques that translates to is constantly changing, but that’s not the point here). A critical skill that I’d love to see more evidence of in our industry is the most senior guys not only being able to work at the right-end of the SEMS, but more importantly be able to consciously work at any point along the SEMS as project needs dictate. An even more valuable skill would be if you could make the conscious decision to move a projects code further right on the SEMS (based on changing needs) and do so in an incremental manner without having to start from scratch. An exercise that I’m planning to go through with all of our projects here at Anvil in the near future is to map out where I believe each project currently falls within this SEMS, where I believe the project *should* be on the SEMS based on the business needs, and for those that don’t match up (i.e. most of them) come up with a plan to improve the situation.

• Pure-FTPd linux upload problems - 500 Unknown command

  - by user1801273

  I'm running Centos with Kloxo CP and PureFTPd on VPS based on HyperVM. The problem - during the day, there are periods when FTP wors fine for hours, but sometimes it dies with "500 Unknown command" code. for files larger than 2Kb. This is really weird - with files less than 2472-2484 bytes everything would work fine, but with bigger files ftp would start writing file, would drop on 2Kb and would return "500 Unknown command" . This happens on Passive AND/OR Active connections for any filetypes. Logs are showing like the file was uploaded successfully , but the speed nearby the action would be 0.3 -0.5 Kb , when normal operation would report 70-150Kb/s speeds. I do have some Iptables firewalls on both HyperVM host,and VPS , however these are static, and most of the time it works just fine. Any suggestions on where to look for a solution would be appreciated :)

• Oracle Insurance Gets Innovative with Insurance Business Intelligence

  - by nicole.bruns(at)oracle.com

  Oracle Insurance announced yesterday the availability of Oracle Insurance Insight 7.0, an insurance-specific data warehouse and business intelligence (BI) system that transforms the traditional approach to BI by involving business users in the creation and maintenance."Rapid access to business intelligence is essential to compete and thrive in today's insurance industry," said Srini Venkatasantham, vice president, Product Strategy, Oracle Insurance. "The adaptive data modeling approach of Oracle Insurance Insight 7.0, combined with the insurance-specific data model, offers global insurance companies a faster, easier way to get the intelligence they need to make better-informed business decisions." New Features in Oracle Insurance 7.0 include:"Adaptive Data Modeling" via the new warehouse palette: Gives business users the power to configure lines of business via an easy-to-use warehouse palette tool. Oracle Insurance Insight then automatically creates data warehouse elements - such as line-specific database structures and extract-transform-load (ETL) processes -speeding up time-to-value for BI initiatives. Out-of-the-box insurance models or create-from-scratch option: Includes pre-built content and interfaces for six Property and Casualty (P&C) lines. Additionally, insurers can use the warehouse palette to deploy any and all P&C or General Insurance lines of business from scratch, helping insurers support operations in any country.Leverages Oracle technologies: In addition to Oracle Business Intelligence Enterprise Edition, the solution includes Oracle Database 11g as well as Oracle Data Integrator Enterprise Edition 11g, which delivers Extract, Load and Transform (E-L-T) architecture and eliminates the need for a separate transformation server. Additionally, the expanded Oracle technology infrastructure enables support for Oracle Exadata. Martina Conlon, a Principal with Novarica's Insurance practice, and author of Business Intelligence in Insurance: Current State, Challenges, and Expectations says, "The need for continued investment by insurers in business intelligence capabilities is widely understood, and the industry is acting. Arming the business intelligence implementation with predefined insurance specific content, and flexible and configurable technology will get these projects up and running faster."Learn moreTo see a demo of the Oracle Insurance Insight system, click hereTo read the press announcement, click here

• 2D Procedural Terrain with box2d Assets

  - by Alex

  I'm making a game that invloves a tire moving through terrain that is generated randomly over 1000 points. The terrain is always a downwards incline like so: The actual box2d terrain extends one screen width behind and infront of the circular character. I'm now at a stage where I need to add gameplay elements to the terrain such as chasms or physical objects (like the demo polygon in the picture) and am not sure of the best way to structure the procedural generation of the terrain and objects. I currently have a very simple for loop like so: for(int i = 0; i < kMaxHillPoints; i++) { hillKeyPoints[i] = CGPointMake(terrainX, terrainY); if(i%50 == 0) { i += [self generateCasmAtIndex:i]; } terrainX += winsize.width/20; terrainY -= random() % ((int) winsize.height/20); } With the generateCasmAtIndex function add points to the hillKeyPoints array and incrementing the for loop by the required amount. If I want to generate box2d objects as well for specific terrain elements, I'll also have to keep track of the current position of the player and have some sort of array of box2d objects that need to be created at certain locations. I am not sure of an efficient way to accomplish this procedural generation of terrain elements with accompanying box2d objects. My thoughts are: 1) Have many functions for each terrain element (chasm, jump etc.) which add elements to be drawn to an array that is check on each game step - similar to what I've shown above. 2) Create an array of terrain element objects that string together and are looped over to create the terrain and generate the box2d objects. Each object would hold an array of points to be drawn and and array of accompanying box2d objects. Any help on this is much appreciated as I cannot see a 'clean' solution.

• Should interfaces extend (and in doing so inherit methods of) other interfaces

  - by dreza

  Although this is a general question it is also specific to a problem I am currently experiencing. I currently have an interface specified in my solution called public interface IContextProvider { IDataContext { get; set; } IAreaContext { get; set; } } This interface is often used throughout the program and hence I have easy access to the objects I need. However at a fairly low level of a part of my program I need access to another class that will use IAreaContext and perform some operations off it. So I have created another factory interface to do this creation called: public interface IEventContextFactory { IEventContext CreateEventContext(int eventId); } I have a class that implements the IContextProvider and is injected using NinJect. The problem I have is that the area where I need to use this IEventContextFactory has access to the IContextProvider only and itself uses another class which will need this new interface. I don't want to have to instantiate this implementation of IEventContextFactory at the low level and would rather work with the IEventContextFactory interface throughout. However I also don't want to have to inject another parameter through the constructors just to have it passed through to the class that needs it i.e. // example of problem public class MyClass { public MyClass(IContextProvider context, IEventContextFactory event) { _context = context; _event = event; } public void DoSomething() { // the only place _event is used in the class is to pass it through var myClass = new MyChildClass(_event); myClass.PerformCalculation(); } } So my main question is, would this be acceptable or is it even common or good practice to do something like this (interface extend another an interface): public interface IContextProvider : IEventContextFactory or should I consider better alternatives to achieving what I need. If I have not provided enough information to give suggestions let me know and I can provide more.

• Ubuntu boots into command line instead of X.

  - by Ethan Turkeltaub

  I posted this on the Ubuntu forums and they had no good answer. I hope you guys have a solution! On my relatively new install, it's booting into command line instead of X--again. This is the reason I reinstalled in the first place. This has happened to me three times now. So, I boot up and it gets past GRUB, past the glowing Ubuntu option, then it prompts me for my username, then password. I run: startx And that starts the GUI for about a minute, then it runs the GUI login system. To add to the mess, the network-applet is not shown in the panel. Additionally, Chrome will not launch (I ran Firefox from the terminal). What's the problem here?

• Track a Adobe Flash app hosted on multiple domains with Google Analytics

  - by roberkules

  I'm working on a flash app that's gonna be distributed to more and more partners (and obviously domains). It needs to be tracked aggregated and also separately. I implemented Google Analytics using gaforflash, tracking virtual pageviews and events inside the flash app. What I want to achieve: View an aggregated report of all partners. Identify the partner not by the domain (where the flash is used), but by a partnerID. Each partner needs access to the report of his domain. (no admin rights needed) I came up with this solution: Using only one "Web property" in Google Analytics. UA-XXXXXX-4 .example.com Set a custom/virtual hostname per partner. (GA's "utmhn" parameter) partner1.example.com partner2.example.com Create a profile for each partner, setting the filter to include only the relevant "subdomain" Problems that came up: The gaforflash library doesn't support overriding the host name. Possible workaround: The gaforflash source code is available, so I could add the functionality. Any goal from the "master" profile is not copied to the partners profile. profile 1: include traffic from hostname ^partner1\. profile 2: include traffic from hostname ^partner2\. Is it (very) bad to fake the hostname? Are there better approaches? Or what improvements could you think of? UPDATE: I'm looking primarily for a solid data structure inside Google Analytics regardless of the flash implementation. The only limitations: We need an aggregated view across all partners Our partners need to have access to their subset of data We want to identify the partner by a custom partnerID, not the domain

• Tunneling traffic through two VPN hops/tunnels.

  - by Roberto Sebestyen

  I am a web developer, and I find myself often working from home. But when I do, I am forced to Remote Desktop to the Office desktop computer and work from there. The reason is because the application I am working on needs to connect to servers at a Data Center via a VPN from the Office Desktop. HomeDesktop (Win7) --- PVN --- OfficeDesktop(WinXP) --- VPN --- Data Center What I would really like to do is, I would like to find a way to be using my Home desktop developing on that, and whenever my computer tries to access servers on the Data Center, I would like to tunnel that traffic through the two VPN tunnels separating me and the Data Center. I have admin privileges on both Office Desktop and Home Desktop, but I do not have any admin privileges in the Data Center. So what kind of tunneling solution could I use here? Is it even possible?

• Load balancing Apache on a budget?

  - by Industrial

  Hi everyone, I am trying to get my head around the concept of load balancing to ensure availability and redundancy to keep users happy when things go wrong, rather than load balancing for the sake of offering blistering speed to millions of users. We're on a budget and trying to stick to the stuff where there's plenty of knowledge available, so running Apache on Ubuntu VPS's seems like the strategy until some famous search engine acquire us (Saturday irony included, please note). At least to me, it's a complete jungle of different solutions available. Apaches own mod_proxy & HAproxy are two that we found by a quick google search, but having zero experience of load balancing, I have no idea of what would be appropriate for our situation, or what we would look after while choosing a solution to solve our availability concerns. What is the best option for us? What should we do to get availability high whilst staying inside our budgets?

• Firefox does not print flash content

  - by Rochelle

  I am using Firefox 3.6.15 on a Windows 7 Professional, 64-bit Operating System, Intel Core i7 CPU, 3.33GHz, 10BG RAM, by Hewlett-Packard. Firefox does not print flash content, aka swf objects, nor does it show them in the print preview pane...I want to print out the entire web page with the flash content. I seem to only be able to see flash and html content together in print preview and to print in IE8. I have tried to google this issue, but could not find a solution. I was trying to print preview/print out the following site: http://www.discovertheponds.com/. Flash content will display in print preview and print in IE8, but neither print preview or print in Firefox. I have also updated the Java on my computer to the most recent update, and ran the firefox plug-in checker at http://www.mozilla.com/en-US/plugincheck/ . I do run Firebug and Web Developer, but have currently disabled them. Is this problem on my end, meaning some issue with my computer...or is this because of how the website was programmed in HTML/Flash...or is this a bug with Firefox? I am a website designer and am also concerned that others will not be able print sites I develop or have already developed that have flash content from Firefox. I used to think Firefox was better than IE at everything. What happened here? Was it some change in Firefox's version that caused this problem?

• What's the simplest way to serve RhodeCode over HTTPS on windows?

  - by Keith Nicholas

  I have RhodeCode working with http using the paster serve tool that it comes with... I'm struggling to find a "simple" solution to get this running on HTTPS. A lot of discussion is about using Apache to do this on unix. Not a lot of info on how to do it on IIS. I was looking at paster serve and it seems to be able to serve using HTTPS, but can't quite work out how to get this going. However the real goal is just to serve RhodeCode over HTTPS in the simplest way possible ( all self contained would be brilliant).

• How do you create large, growable, shared filesystems on Linux at AWS?

  - by Reece

  What are acceptable/reasonable/best ways to provide large, growable, shared storage at AWS, exposed as a single filesystem? We're currently making 1TB EBS volumes ~biweekly and NFS exporting with no_subtree_check and nohide. In this setup, distinct exports appear under a single mount on the client. This arrangement does not scale well. The options we've considered: LVM2 with ext4. resize2fs is too slow. Btrfs on Linux. not obviously ready for prime time yet. ZFS on Linux. not obviously ready for prime time yet (although LLNL uses it) ZFS on Solaris. future of this combo is uncertain (to me), and new OS in the mix glusterfs. heard mostly good but two scary (and maybe old?) stories. The ideal solution would provide sharing, a single fs view, easy expandability, snapshots, and replication. Thanks for sharing ideas and experience.

• Out of sync audio / video on Hackintosh

  - by user22902

  I have a PC with OSx86 (10.6.2) on it. Under Leopard my videos worked great, but now with VLC the audio is all garbled and video is way too fast. In Quicktime X video is too fast. MPlayer OSX Extended plays videos fine, but doesn't support many codecs. I have a Geforce 9800 GTX with qe ci ocl... If theres no solution, then are there any other players for OS X that support a lot of codecs? I don't like Windows so that's not an option. Thanks

• Is there a way to copy the file paths of ALL active windows' opened files?

  - by frenchglen

  The context of this question, is here. I actually know the answer to my question is yes - like I say in my context, this program can do it (somehow). So the really question is, how can I do it. What code do I put in a simple batch file? (or do I have to compile a tiny c++ exe? and run that exe in the batch file?) Might this code be a solution? (.....EnumDesktopWindows?) To clarify, I know that there's e.g. NirSoft OpenedFilesView which shows allll the technically-opened files in Windows, but it's just the 'visible' user-opened ones that I'm after (whatever you can see in Task Manager's Applications tab). Thanks.
