• How to decide how backward-compatible my new Mac OS X application should be?

  - by haimg

  I'm currently contemplating writing an OS X version of my Windows software. My Windows application still supports Windows XP, and I know that if I drop support for it now, our customers will cry bloody murder. I'm new to OS X development, and as I learn the technology, APIs, etc., I realized that if I'm going to provide comparable level of backward compatibility (e.g. down to OS X 10.5), I would not be able to use many things that look very useful and relevant in my case (ARC, XPC communications, many others). This is quite different from Windows, in my opinion, where there are very little changed between Windows XP and Windows 7 from desktop application developer's standpoint. So, on one hand, it seems like a complete waste to stick to 2007 or 2009-level API in 2012. On the other hand, according to NetMarketShare report and Stat Owl report Mac OS X 10.5 and 10.6 market share is still 11% and 35%-40% respectively. However, I'm not sure if these older OS users are my target audience (buyers of software utilities) if they didn't bother to upgrade their OS... My question: Are there any other reasons I should take into account when deciding if I target 10.5 or 10.6 or 10.7 for a new application?

• You may be tempted by IaaS, but you should PaaS on that or your database cloud journey will be a short one

  - by B R Clouse

  Before we examine Consolidation, the next step in the journey to cloud, let's take a short detour to address a critical choice you will face at the outset of your journey: whether to deploy your databases in virtual machines or not. A common misconception we've encountered is the belief that moving to cloud computing can be accomplished by simply hosting one's current operating environment as-is within virtual machines, and then stacking those VMs together in a consolidated environment.  This solution is often described as "Infrastructure as a Service" (IaaS) because the building block for deployments is a VM, which behaves like a full complement of infrastructure.  This approach is easy to understand and may feel like a good first step, but it won't take your databases very far in the journey to cloud computing.  In fact, if you follow the IaaS fork in the road, your journey will end quickly, without realizing the full benefits of cloud computing.  The better option to is to rationalize the deployment stack so that VMs are needed only for exceptional cases.  By settling on a standard operating system and patch level, you create an infrastructure that potentially all of your databases can share.  Now, the building block will be database instances or possibly schemas within databases.  These components are the platforms on which you will deploy workloads, hence this is known as "Platform as a Service" (PaaS). PaaS opens the door to higher degrees of consolidation than IaaS, because with PaaS you will not need to accommodate the footprint (operating system, hypervisor, processes, ...) that each VM brings with it.  You will also reduce your maintenance overheard if you move forward without the VMs and their O/Ses to patch and monitor.  So while IaaS simply shuffles complex and varied environments into VMs,  PaaS actually reduces complexity by rationalizing to the small possible set of components.  Now we're ready to look at the consolidation options that PaaS provides -- in our next blog posting.

• Is individual code ownership important?

  - by Jim Puls

  I'm in the midst of an argument with some coworkers over whether team ownership of the entire codebase is better than individual ownership of components of it. I'm a huge proponent of assigning every member of the team a roughly equal share of the codebase. It lets people take pride in their creation, gives the bug screeners an obvious first place to assign incoming tickets, and helps to alleviate "broken window syndrome". It also concentrates knowledge of specific functionality with one (or two) team members making bug fixes much easier. Most of all, it puts the final say on major decisions with one person who has a lot of input instead of with a committee. I'm not advocating for requiring permission if somebody else wants to change your code; maybe have the code review always be to the owner, sure. Nor am I suggesting building knowledge silos: there should be nothing exclusive about this ownership. But when suggesting this to my coworkers, I got a ton of pushback, certainly much more than I expected. So I ask the community: what are your opinions on working with a team on a large codebase? Is there something I'm missing about vigilantly maintaining collective ownership?

• What are my choices for server side sandboxed scripting?

  - by alfa64

  I'm building a public website where users share data and scripts to run over some data. The scripts are run serverside in some sort of sandbox without other interaction this cycle: my Perl program reads from a database a User made script, adds the data to be processed into the script ( ie: a JSON document) then calls the interpreter, it returns the response( a JSON document or plain text), i save it to the database with my perl script. The script should be able to have some access to built in functions added to the scripting language by myself, but nothing more. So i've stumbled upon node.js as a javascript interpreter, and and hour or so ago with Google's V8(does v8 makes sense for this kind of thing?). CoffeeScript also came to my mind, since it looks nice and it's still Javascript. I think javascript is widespread enough and more "sandboxeable" since it doesn't have OS calls or anything remotely insecure ( i think ). by the way, i'm writing the system on Perl and Php for the front end. To improve the question: I'm choosing Javascript because i think is secure and simple enough to implement with node.js, but what other alternatives are for achieving this kind of task? Lua? Python? I just can't find information on how to run a sandboxed interpreter in a proper way.

• Naming conventions: camelCase versus underscore_case ? what are your thoughts about it?

  - by poelinca

  I've been using underscore_case for about 2 years and I recently switched to camelCase because of the new job (been using the later one for about 2 months and I still think underscore_case is better suited for large projects where there are alot of programmers involved, mainly because the code is easyer to read). Now everybody at work uses camelCase because (so they say) the code looks more elegant . What are you're thoughts about camelCase or underscore_case p.s. please excuse my bad english Edit Some update first: platform used is PHP (but I'm not expecting strict PHP platform related answers , anybody can share their thoughts on which would be the best to use , that's why I came here in the first place) I use camelCase just as everibody else in the team (just as most of you recomend) we use Zend Framework which also recommends camelCase Some examples (related to PHP) : Codeigniter framework recommends underscore_case , and honestly the code is easier to read . ZF recomends camelCase and I'm not the only one who thinks ZF code is a tad harder to follow through. So my question would be rephrased: Let's take a case where you have the platform Foo which doesn't recommend any naming conventions and it's the team leader's choice to pick one. You are that team leader, why would you pick camelCase or why underscore_case? p.s. thanks everybody for the prompt answers so far

• Network print to brother MFC-7420

  - by trampster

  I am trying to pint to a Brother MFC-7420 from my ubuntu 10.04 machine. The brother is attached to a windows XP machine and is shared. This is what I have tried: System-Administration-Printing, Add, Expand Network Printer, Windows Printer via SAMBA, Browse (I can find the printer no problems here), Foward, Choose Driver Dialog, Brother, My printer is not in this list So the next thing I tried was to download the printer driver from here http://welcome.solutions.brother.com/bsc/public_s/id/linux/en/download_prn.html The driver installed fine but my printer still does not appear in the list. I also tried installing the cups wrapper but that gave the following error. Restarting Common Unix Printing System: cupsd [ OK ] cp: cannot stat `/usr/share/cups/model/MFC7420.ppd': No such file or directory dpkg: error processing cupswrappermfc7420 (--install): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: cupswrappermfc7420 I tried connecting the printer directly but even though I have installed the driver, when I go to printers and click on the printer (it shows up fine as a USB printer) then it say searching for drivers and then gives me a list, this is the same list as before which doesn't have my printer. It really shouldn't be this hard. on window you don't have to installing anything it just works and the same is true for my brothers Mac. How do I print to my printer?

• SEO & Multilingual: would be this a good practise?

  - by Younès

  I am currently making a bilingual website and I'd like to get nice SEO results of course. Here's my idea: The internal links would be composed of the "www" subdomain so that people can share links regardless of their language. Anyway, their language is determined by the HTTP_ACCEPT_LANGUAGE PHP variable. So, they would see http:// www.site.com/mydocument/123 in their adress bar and never see any links like "http:// fr.site.com/mydocument/123" or "http://en.site.com/mydocument/123" The user can always switch the page's language thanks to links in the footer. The switching language link would be : http:// fr.site.com/mydocument/123 , and clicking on it would change his language session and redirects the user to http:// www.site.com/mydocument/123 In case of a crawling bot: I read that if the HTTP_USER_LANGUAGE variable was missing then it's a crawling bot. So, in that case, we set the defaut language as English. Each page, as I mentionned earlier, has a link for another language: On the page: http:// www.site.com/document/1323, the link http:// fr.site.com/document/1323 can be seen by the bot and be crawled. What do you think about this practise ? Would I get good SEO results for each language ?

• Geekswithblogs.net | Screen Resolutions of our Readers

  - by Jeff Julian

  Yesterday I talked about the Browsers we see being used by our readers driven off of our Google Analytics traffic and today I want to share with you the Screen Resolutions we see.  As a web developer most of my life, it is hard to decide how large you should build your application because typically you have a couple huge high resolution monitors on your desk, but you typical end user is thought to have 1024x768.  With HTML5/CSS3 out, it is a little better coming up with a design that will scale to all resolutions, but it is still nice to know the numbers when it comes to how much real estate do I have on my clients. If you look at these numbers for Geekswithblogs.net, we have a lot of high resolution monitors from users that visit the site.  After a little more investigation of the number you will notice we do not have as much height available as we do width.  If the primary goal of a site is to deliver as much data in the viewable area without scrolling, this becomes a challenge when most of our pages have long pieces of formatted data.  So our challenge is to build skins that use up more of the sides of the content toward the top on larger resolution browsers and then entice the reader to scroll to get the goodies embedded in the content of the posts.  Going to be an interesting battle for sure, but we really need more skin offerings on the site.

• How to implement "bullet time" in a multiplayer game?

  - by Tom

  I have never seen such a feature before, but it should provide an interesting gameplay opportunity. So yes, in a multiplayer/real-time environment (imagine FPS), how could I implement a slow motion/bullet time effect? Something like an illusion for the player that's currently slo-mo'ed. So everybody sees him "real-time", but he sees everything slowed down. Update A sidenote: keep in mind that a FPS game has to be balanced in order for it to be fun. So yes, this bullet time feature has to be solid, giving a small advantage to the "player", while not taking away from other players. Plus, there is a possibility that two players could activate their bullet time at the same time. Furthermore: I'm going to implement this in the future no matter what it takes. And, the idea is to build a whole new game engine for all this. If that gives new options, I'm more then interested in hearing the ideas. Meanwhile, here with my team we're thinking about this too, when our theory will be crafted, I'm going to share it here. Is this even possible? So, the question on "is this even possible" has been answered, now it's time to find the best solution. I'm keeping the "answer" until something exceptionally good comes up, like a prototype theory with something close to working pseudo code.

• Banshee doesn't like opening websites

  - by Allan

  I have come across two bugs (which will be added to launchpad if it's not resolved here) When I open any of the websites in Banshee Amazon or Miro Guide as soon as the site is finished loading it crashes Banshee. If I play any video local or remote it will show 1 frame maybe 0.5 sec of video then I get a black screen and audio continues in the backgound. Specs & Details I have a Fujitsu Amilo 1718 laptop with 2 gig of ram (original 1 gig) graphics is provided by ATI Radeon Xpress 200M (don't laugh it works with compiz....just) I have a link to the output of banshee --debug Here Don't have time to read?

• Employee Engagement: Drive Business Value

  - by Kellsey Ruppel

  As we’ve been discussing this week, employee engagement is extremely important and you’ve probably realized that effectively engaging your employees is essential to driving business value. Your employees are the ones responsible for executing on the business’ objectives. Your employees (in the sales & service departments) are the ones interacting with your customers the most, so delivering on customer expectations and attaining high levels of customer engagement are simply not possible without successfully empowering these this stakeholder group. High employee and partner engagement can have many benefits including: Higher levels of employee productivity Longer employee retention Stronger, more enduring and more successful relationships Serving as ambassadors for an organization’s brand More likely to deliver excellent customer service Referring others for hire Recommending the organization’s products and services Sharing feedback with their colleagues In a way, engagement is a measure of employee investment in an organization’s mission and brand. And then you have the enablement piece of this as well.  It’s hard to imagine a high level of engagement existing among employees who don’t feel that they’ve been enabled to do their jobs very efficiently or effectively. You’re just not going to find high engagement among people if the everyday processes and technologies  they work with make it a challenge for them to access, share and manage the information  they need do their jobs or if they’re unable to effectively collaborate around the projects they’re working on. How does your organization measure on the employee engagement spectrum? We’ve got a number of different resources to help you get started! Portal Resource Center Video: Got a minute?

• How to justify rewriting/revamping legacy software in a business case?

  - by sxthomson

  I work for a great little software company which makes good revenue from our main software package. The problem for me is that it's almost unmaintainable. It's written in Delphi 7 (has upgraded versions over time) and has been worked on by a lot of developers over the past 20 or so years. The software lacks any meaningful architecture - there's no object orientation whatsoever, horrible amounts of cyclical dependencies and an over-reliance on global variables to name just a few things. Another huge thing for me is Delphi 7 does NOT support 64-bit. The problem here for me is that my management team don't care about technical things, they want to know why they should care. Obviously that's expected, so what I'm asking here is for some guidance, or tales, or pitfalls about this kind of thing. There's a few things I would love to include, namely for me, the length of time taken to debug/write a feature in "legacy" code, versus coherent, well structured OO code. Does anyone know of any blog posts or the like where this is talked about? For us in the company this is a huge reason. Despite being decent developers we feel like writing a new feature is just piling more rubbish on top. On top of that, even for me who has a decent level of understanding of the code, changing things is infuriating - a small change can have a ridiculous domino effect. Anyone have any experiences they'd like to share?

• Software development company business plan

  - by Navi

  I apologize in advance if this is the wrong forum for this question, so please forward me to the right place. I have about 10 years professional experience as software developer. Mostly on the Java platform doing server side programs. I have picked up a bit of Linux skills on the way as well. I know HTML and Javascript, so I can make a website that would not be too ugly, but I am not going to win any prizes with it. In fact I think I am pretty terrible in the user interface department. My initial plan is to do Android development. I read a few Android books and tried making a few apps. Since it is Java based I think I got the technical side down. Lately I have been thinking about iphone and Mac development, because of the relevant app store/development programs. The trouble is I don't know Objective C. As a side question, how long would it take me to become proficient in Objective C? Considering that I am working on my own and could hire somebody to help me for a short time for low wages if necessary what are my options? What are the pro and cons of the development programs app stores of Android and Apple? Which development/app stores are out there beside the ones I mentioned? Do you think it is necessary to find funds to get me started or should I just use my savings? If you have positive/negative experiences in a similar situations can you please share them? Thanks for your help.

• SQL Source Control Contest

  - by Ajarn Mark Caldwell

  If you’re a regular reader of this blog, you know that I have written several posts about how important I think it is to protect your source code, to version it, and in particular, all the aspects I like about Red Gate’s SQL Source Control product.  But for a moment, let’s take a break from my writing and I want to hear your stories.  What nightmare situation are you in, or can you imagine, where source control for your database would save the world.  Or maybe your life is not so dramatic, but you do see a challenge that, if you just had a good tool like SQL Source Control, it would go much smoother.  What’s your pain?  You have read my writings, now tell me your story, and be in the running for a free copy of SQL Source Control from Red Gate. Yes, that’s right.  Although I am just a fan of Red Gate, they have authorized me to give out a handful of licenses to blog readers who are willing to share their story by posting a comment to this blog entry.  Simply add your comment below (be sure to include a valid email address in the box that asks for that) to be entered.  The contest starts immediately and over the next few days, the best stories will win.

• Dynamic Jump spot

  - by Pasquale Sada

  I have an initial velocity V(Vx,Vy,VZ) and a spot where he stands still at S(Sx,Sy,Sz). What I'm trying to achieve is a jump on a spot E(Ex,Ey,Ez) where you have clicked on(only lower or higher spot, because I've in place a simple steering behavior for even terrains). There are no obstacle around. I've implemented a formula that can make him jump in a precise way on a spot but you need to declare an angle: the problem arise when the selected spot is straight above your head. It' pretty lame that the char hang there and can reach a thing that is 1cm above is head. I'll share the code I'm using: Vector3 dir = target - transform.position; // get target direction float h = dir.y; // get height difference dir.y = 0; // retain only the horizontal direction float dist = dir.magnitude ; // get horizontal distance float a = angle * Mathf.Deg2Rad; // convert angle to radians dir.y = dist * Mathf.Tan(a); // set dir to the elevation angle dist += h / Mathf.Tan(a); // correct for small height differences // calculate the velocity magnitude float vel = Mathf.Sqrt(dist * Physics.gravity.magnitude / Mathf.Sin(2 *a)); return vel * dir.normalized;

• Designing a system with different business rules for different customers

  - by user1595846

  My company is rewriting our proprietary business application. The current architecture is poorly done and inflexible. It is coded more procedural oriented as opposed to object oriented. It has become difficult to maintain. Our system is a web application written in .Net Webforms. I am considering ASP.Net MVC for the rewrite. We intend to rewrite it with a good, solid architecture with the goal of maintainability and reusable classes for some of our other systems and services. We would also like the system to be customizable for different customers in the event that we market the system. I am considering redesigning the system based on the layered architecture (Presentation, Business, Data Access layers) described in the Microsoft Patterns and Practices Application Architecture Guide. http://msdn.microsoft.com/en-us/library/ff650706.aspx Hopefully this isn't too open ended, but how would you recommend allowing for different business logic/rules for different customers? I'm aware of Windows Workflow Foundation, but from what I've read about it, it seems many business rules could be too complicated to handle there. Also, Can anyone point me to where I can download an example of a .net solution that is based on the Application Architecture Guide? I have already downloaded the Layered Architecture Solution Guidance and the Expense Sample on codeplex. I was looking for something a bit larger and more robust that I could step through the code and see how it works. If you feel there are better architectures to base our redesign on please feel free to share. I appreciate your help!

• Need advice concerning Feature Based Development when knowledge DB is involved

  - by voroninp

  We develop BackOffice application which is used to edit our knowledge DB. Now our main product's development team is shifting to the feature based development and we need to support several DB's with not identical data schemes. (DS changes slightly from DB to DB) The information from knowledge Db is extracted by the script and then is distributed to the clients. We also need to support merging these DB's. We now analyze pros and cons of different approaches. We discuss this one: One working DB (WDB) with one DB for each feature branch (FDB). The approved data is moved from WDB to FDB. So we need to support only one script for each branch. This script will extract data from corresponding FDB. Nevertheless we are to code the differences between FDBs and WDB manually. May be some automatic mapping tools exist? I also wish to know whether classic solutions to the alike problems already exist. Can anyone share the best practices for this case?

• The SQL Server Setup Portal

  - by BuckWoody

  One of the tasks that takes a long time for the data professional is setting up SQL Server. No, it isn’t that difficult to slide a DVD in a drive and click “Setup” but the overall process of planning the hardware and software environment, making decisions for high-availability, security and dozens of other choices can make the process more difficult. And then, of course, there are the inevitable issues that arise. Microsoft supports literally hundreds and even thousands of combinations of hardware and software drivers from vendors you’ve never even heard of. Making all of that work together is a small miracle, so things are bound to arise that you need to deal with. So, to help you out, we’ve designed a new “SQL Server Setup Portal”. It’s a one-stop-shop for everything you need to know about planning and setting up SQL Server. As time goes on you’ll see even more content added. There are already whitepapers, videos, and multiple places to search on everything from topic names to error codes. So go check it out – and if you have to do a lot of SQL Server Setups – and especially if you don’t – bookmark it as a favorite!

• Interaction between two Clouds

  - by user7969

  I have setup the Cloud-A with 1 - [CLC+CC] and 2 - [NC] computers. I have another Cloud-B with same configuration. [using the Ubuntu Enterprise Cloud] Both of them working fine individually, in the same LAN. Now if I want to add the NC of Cloud-A to CC of Cloud-B, [in case the resources of Cloud-B are exhausted] how can I make it possible ? I guess this calls for the interoperability stuff... Could you please explain what happens exactly when we ask for instance, the direct interaction happens between the client and NC or it goes through the CLC and CC ? What I want to say is, say there are multiple cloud providers. A user is subscribed to any one of them, say Cloud-A for IaaS. As the requirements are dynamic, all the resources of Cloud-A may get exhausted. There may be another Cloud-B which can provide the services but that Cloud-A can't ask the client to go for Cloud-B. So if it is possible to have some co-ordination between this two providers to share resources mutually, making client fully unaware of whats going on in the background....? Please reply.. I am sorry if I'm doing mistake anywhere... Thanks in advance :)

• Grub2 attempting to boot hd1 when it should boot hd0

  - by JoBu1324

  I'm attempting to perform a "normal" install on a USB3 SSD (I don't know if it is noteworthy, but I don't have a swap partition). The installation proceeds normally (I'm installing from a USB2 device I created using LiLi Boot, with a copy of Ubuntu 12.10 64bit that I downloaded directly from the source. The system I'm running Ubuntu on has had a more traditional installation of ubuntu running on it without issue (also 12.10), so I know that everything works A-OK when booting from a 7200RPM internal disk. There are a number of oddities that I've noticed so far, including graphics corruption, but the first and most pressing issue is that Grub2 refuses to recognize the correct hd. From /boot/grub/grub.cfg: if [ x$feature_default_font_path = xy ] ; then font=unicode else insmod part_msdos insmod ext2 set root='hd1,msdos1' if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd1,msdos1 --hint-efi=hd1,msdos1 --hint-baremetal=ahci1,msdos1 b58ee4f7-d41d-400a-b7b8-18bd1f0ae9d3 else search --no-floppy --fs-uuid --set=root b58ee4f7-d41d-400a-b7b8-18bd1f0ae9d3 fi font="/usr/share/grub/unicode.pf2" fi This is from a 100% fresh install of linux (first boot), which was installed while no hard drives were connected to the system, other than the USB2 LiLi drive. The system refuses to boot unless I change the hd1,msdos1 - hd0,msdos1 in the grub menu at boot, when it is the only disk device connected to the PC. What options are left for me to troubleshoot this issue? I've been racking my brains and taxing the internet trying to dig up something on this problem, but now I'd like to see if the Ubuntu community can rise to the challenge and help me fix this boot problem. This is the second time I've attempted this particular setup. The first time, after days of wasted time, I managed to get it to boot every other boot - i.e. every even boot it would boot into Ubuntu like it was happy; every odd boot it would boot into the BusyBox or Grub prompt. At one point it complained that it couldn't find /dev/disk/by-uuid/[the disk], which I found most perplexing, since the disk was there and booted before and after the occurrence (with intervention).

• I just recursively chmod'd everything under / to 750. Any tips?

  - by Ouairz

  I won't be the first and I won't be the last, I suppose. While playing around with the find command, I made a whoops and it would appear that instead of changing the permissions of the ~/web directory to 750, it changed the permissions of the entire filesystem (/) to 750, however I'm not certain, but any attempt to investigate is thwarted by Permission denied messages. For everything. This was the offending command: sudo find ~/web . type d -exec chmod 750 {} If I'm not mistaken, the Ubuntu team disabled root logins as a safety precaution so I'm out of ideas. I'm (obviously) a total newbie when it comes to file permissions so I was wondering if anyone had some good or even some bad advice to share. I've mentally prepped myself to losing everything on the computer which is only of mild consequence, since I have backups, but I did do a bit of work on this box over the week and it would be a shame to lose it all due to a boneheaded mistake. If you are reading this message, ask yourself, have you backed up any of your work recently? Thanks in advance for any insights. Feel free to scold me for using sudo carelessly
