• Career Advice: finding challenging work in software and web development

  - by dianovich

  Having left my physics degree early, I started out in the realm of web design / front end web development and was able to get work quite quickly. I moved on to spend a chunk of my time on servers and gained experience with frameworks like Wordpress and Drupal, then the likes of Codeigniter and CakePHP and became comfortable in Debian-based and RHEL/CentOS environments. I ventured in to iOS development and published a couple of native apps to the app store too! I have started to spend a good deal of my time writing Python and have invested a little time in Django. The problem is, I still spend a fair chunk of my time doing more front end web development (writing markup and CSS for site themes, design-lead JavaScript, small applications for which application architecture and software engineering are relatively unimportant or too time consuming to invest in) in my job. What I want to do is really exercise the systematic/logical portion of my brain and tackle challenging problems on a daily basis. I want to have to care about big-oh running times, modularity in software, DRY, performance tuning and development methodologies. I want to work for a firm whose clients say: "Yes, these things are important to us and we'll pay you to get them right." But it is difficult: I have no formal training and am potentially becoming a jack of all trades. Not that being a jack of many trades is necessarily a bad thing, but the scope of work I find myself involved in is far too broad. And, there are only so many hours in a day outside of work! My question is: where do I go from here? I am starting to work on a few open source projects and have started to publish content to my blog. But this isn't likely to make it past the recruitment consultants and HR departments of many-a-firm. And I do not, for example, work in a team that practices agile methodologies, so how do I get work in such a team to gain experience? While I have been responsible for implementing version control and some solid working practices into our current environment, there is only so far I can go in this context. What would convince you that i'm worth taking a risk? What would convince you that i'll have caught up the other guys in your employ in next to no time?

• Is there a language or design pattern that allows the *removal* of object behavior or properties in a class hierarchy?

  - by Sebastien Diot

  A well-know shortcoming of traditional class hierarchies is that they are bad when it comes to model the real world. As an example, trying to represent animals species with classes. There are actually several problems when doing that, but one that I never saw a solution to is when a sub-class "looses" a behavior or properties that was defined in a super-class, like a penguin not being able to fly (there are probably better examples, but that's the first one that comes to my mind, having seen "Madagascar 2" recently). On the one hand, you don't want to define for every property and behavior some flag that specifies if it is at all present, and check it every time before accessing that behavior or property. You would just like to say that birds can fly, simply and clearly, in the Bird class. But then it would be nice if one could define "exceptions" afterward, without having to use some horrible hacks everywhere. This often happens when a system has been productive for a while. You suddenly find an "exception" that doesn't fit in the original design at all, and you don't want to change a large portion of your code to accommodate it. So, is there some language or design patterns that can cleanly handle this problem, without requiring major changes to the "super-class", and all the code that uses it? Even if a solution only handle a specific case, several solutions might together form a complete strategy. [EDIT] Forgot about the Liskov Substitution Principle. That is why you can't do it. Assuming you define "traits/interfaces" for all major "feature groups", you can freely implement traits in different branches of the hierarchy, like the Flying trait could be implemented by Birds, and some special kind of squirrels and fish. So my question could amount to "How could I un-implement a trait?" If your super-class is a Java Serializable, you have to be one too, even if there is no way for you to serialize your state, for example if you contained a "Socket". So one way to do it is to always define all your traits in pair from the start: Flying and NotFlying (which would throw UnsupportedOperationExceiption, if not checked against). The Not-trait would not define any new interface, and could be simply checked for. Sounds like a "cheap" solution, in particular if used from the start.

• Why learn Flash Builder 4 (Flex) when I can just use Flash Professional?

  - by Jason McKenna

  I want to learn Flash Builder 4 (Flex) because I see so many jobs requesting experience with it. I also just like knowing stuff. I am also very interested in focusing on RIA development now. BUT... can anyone tell me CLEARLY why the heck I would ever use FLEX over Flash Pro? It is a time investment, so is it worth it? All I read are misguided posts about how Flash Pro is for games and banner ads, and Flex is for programmers and RIAs blah blah... this simply isn't so from my 9 years of contracting experience. I'm 99.9% certain that I can build anything a flex developer can build, but using Flash Pro. I can build powerful AS3-driven apps for the desktop, mobile device, or browser, and I can link to databases with XML and I can import text files and communicate with ColdFusion and everything. The advantage with Flash Pro is that I can also easily and clearly animate transitions and build custom elements that look the way I want/need them to look for my specific client. Why would I want to use a bunch of pre-built components that drive my file sizes to the moon? Who is happy with a drag-n-drop button? Is Flex just a thing made for programmer people with no artistic inclination? What is the advantage of using it? It takes me back to Visual Basic class. Seems like a pain to have to use multiple tools to import crap from Flash Pro into Flex and yada yada... why when I can do it all nicely in Flash Pro to begin with. Am I clueless, or missing some major piece of the puzzle? Thanks for any clarity. PS, I couldn't care less about the code editors. It ain't that bad people. They make it out like the thing doesn't even respond to keyboard input or something. Does everything I need it do anyways. Please help out here. If I just don't need to learn it, I don't want to waste the time.

• Audio Stutters at gdm

  - by Allan

  Ok I have a problem every 2 times out of 3 I login (I cant be specific it fairly random) I get a Stuttering GDM warning (not the login sound just the Bell sound to wake you up) the only way to stop it is to login I have a Fujitsu Siemens Amilo 1718 with a 2gig of memory (only hardware mod) using 10.10 Maverick and I have disabled KMS as my system was freezing as per the release notes. The only time this has happened before on the same machine was when I gave Kubuntu a try when 10.04 came out then it happened at the login screen and at random times while listening to music in any program. By the way audio is fine as is almost everything else once I have logged in. I would like an answer to this as I am an advocate of Ubuntu and its kind of embarrassing when the first thing that happens is *bing*. as requested Daniel alsa-info Pulse verbose log Not sure how useful the pulse log will be as I cant replicate the bug with a terminal open but I wouldnt be asking the question if I knew the answer so..... Edit 24/12/2010 ......been living on cocktail sausages and pickled onions for five days now made a make shift splint with cocktail sticks..... oops so updated the alsa drivers but I still get the same message in the dmesg No response from codec, disabling MSI: last cmd=0x10a90000 googleing it brings up a forum post from some other distro with a green logo the only common denominator seems to be graphics ie ATI Radeon XPRESS 200M which is why I have had to turn of kms as the chip is so old that small mice try to eat the "kernel" ;) funnily enough following the bug link at the end of the post, I found a comment about "Ubuntu Black Magic" so mabey I am coming at this from the wrong angle...... Bad Joo Joo any one. I will try the second part of Daniels Fix and Update with the result. The final Edit: (Plays air guitar) In the end neither of these solved the problem as such However I have given Roland a tick for reminding me of the solution and I gave Daniel the Bounty for the effort in trying to solve the problem. The answer for future readers was the enable the correct HD Audio Model I found the answer back when using Karmic Koala 9.10 in this forum post Amilo Li1718 Skype - Can't get it working... the model is options snd-hda-intel model=3stack position_fix=1 enable=yes which can be added to the end of alsa-base.conf thanks all for helping and hope anyone with a similar problem will find the answer here.

• Display Driver Issue on an hp TX2-1160ea Notebook

  - by Sam

  I'm new to Linux and recently switched to Ubuntu 11.04 due to my project requirement. My laptop has been freezing and going to black screen of death when I run anything related to display (Share desktop, stream video, etc). Today I went through the Ubuntu forum to install the appropriate graphic driver and, after doing it, I rebooted my PC. It gave an error before login saying "select the recovery mode" and after clicking OK, it didn't give the same error on reboot but I've lost the 11.04 graphical interface and all I see is the interface of Ubuntu v10 with slow visuals (even scrolling up/down on browser is really slow). For the reference, here's a desktop screenshot so that you can understand the situation. Also the laptop is overheating. How can I fix this problem? How can i get the Ubuntu 11.04 view back? I also tried Google, but couldn't find any issue like this.

• Dynamic character animation - Using the physics engine or not

  - by Lex Webb

  I'm planning on building a dynamic reactant animation engine for the characters in my 2D Game. I have already built templates for a skeleton based animation system using key frames and interpolation to specify a limbs position at any given moment in time. I am using Farseer physics (an extension of Box2D) in Monogame/XNA in C# My real question lies in how i go about tying this character animation into the physics engine. I have two options: Moving limbs using physics engine - applying a interpolated force to each limb (dynamic body) in order to attempt to get it to its position as donated by the skeleton animation. Moving limbs by simply changing the position of a fixed body - Updating the new position of each limb manually, attempting to take into account physics collisions. Then stepping the physics after the animation to allow for environment interaction. Each of these methods have their distinct advantages and disadvantages. Physics based movement Advantages: Possibly more natural/realistic movement Better interaction with game objects as force applying to objects colliding with characters would be calculated for me. No need to convert to dynamic bodies when reacting to projectiles/death/fighting. Disadvantages: Possible difficulty in calculating correct amount of force to move a limb a certain distance at a constant rate. Underlying character balance system would need to be created that would need to be robust enough to prevent characters falling over at the touch of a feather. Added code complexity and processing time for the above. Static Object movement Advantages: Easy to interpolate movement of limbs between game steps Moving limbs is as simple as applying a rotation to the skeleton bone. Greater control over limbs, wont need to worry about characters falling over as all animation would be pre-defined. Disadvantages: Possible unnatural movement (Depends entirely on my animation skills!) Bad physics collision reactions with physics engine (Dynamic bodies simply slide out of the way of static objects) Need to calculate collisions with physics objects and my limbs myself and apply directional forces to them. Hard to account for slopes/stairs/non standard planes when animating walking/running animations. Need to convert objects to dynamic when reacting to projectile/fighting/death physics objects. The Question! As you can see, i have thought about this extensively, i have also had Google into physics based animation and have found mostly dissertation papers! Which is filling me with sense that it may a lot more advanced than my mathematics skills. My question is mostly subjective based on my findings above/any experience you may have: Which of the above methods should i use when creating my game? I am willing to spend the time to get a physics solution working if you think it would be possible. In the end i want to provide the most satisfying experience for the gamer, as well as a robust and dynamic system i can use to animate pretty much anything i need.

• WPF: Reloading app parts to handle persistence as well as memory management.

  - by Ingó Vals

  I created a app using Microsoft's WPF. It mostly handles data reading and input as well as associating relations between data within specific parameters. As a total beginner I made some bad design decision ( not so much decisions as using the first thing I got to work ) but now understanding WPF better I'm getting the urge to refactor my code with better design principles. I had several problems but I guess each deserves it's own question for clarity. Here I'm asking for proper ways to handle the data itself. In the original I wrapped each row in a object when fetched from database ( using LINQ to SQL ) somewhat like Active Record just not active or persistence (each app instance had it's own data handling part). The app has subunits handling different aspects. However as it was setup it loaded everything when started. This creates several problems, for example often it wouldn't be neccesary to load a part unless we were specifically going to work with that part so I wan't some form of lazy loading. Also there was problem with inner persistance because you might create a new object/row in one aspect and perhaps set relation between it and different object but the new object wouldn't appear until the program was restarted. Persistance between instances of the app won't be huge problem because of the small amount of people using the program. While I could solve this now using dirty tricks I would rather refactor the program and do it elegantly, Now the question is how. I know there are several ways and a few come to mind: 1) Each aspect of the program is it's own UserControl that get's reloaded/instanced everytime you navigate to it. This ensures you only load up the data you need and you get some persistancy. DB server located on same LAN and tables are small so that shouldn't be a big problem. Minor drawback is that you would have to remember the state of each aspect so you wouldn't always start at beginners square. 2) Having a ViewModel type object at the base level of the app with lazy loading and some kind of timeout. I would then propegate this object down the visual tree to ensure every aspect is getting it's data from the same instance 3) Semi active record data layer with static load methods. 4) Some other idea What in your opinion is the most practical way in WPF, what does MVVM assume?

• So, what&rsquo;s your blog URL?

  - by johndoucette

  Asked by many of my colleagues often enough, I decided to take the plunge and begin blogging. After many attempts to start and long discussions about what I should write about, I decided to give my “buddies” a series of lessons and tidbits to help them understand what it takes to manage a software development project in the real world. Stories of success and failure to keep hope alive. I am formally trained as a developer (BS/CS) and have scattered my code throughout the matrix since 1985 (officially working for the man). As I moved from job-to-job over my career, I have had good managers, bad ones, and ones who were – well, just sitting in the corner office. It wasn't until I began the transition and commitment to the role of project management that I began to take real software development management seriously. A boss once told me “put down the code. Start managing the people and process.” That was a scary time in my career. I loved solving really cool problems with a blank sheet of paper. It was an adrenaline rush to get an opportunity to start from scratch and write an application solution people would actually use and help them in their work/business. I felt that moving into “management” would remove me from the thrill and ownership I felt as a developer. It was a hard step to take, and one which I believe is hard for any developer. Well, I am here to help you through this transition. For those of you wanting to read my stories or learn about the tools and techniques I use on a daily basis, you too might just learn something you would have never thought of as an architect/developer. I am currently a Sr. Consultant at Magenic with the Boston branch office and primarily work with clients in the New England area. I am typically engaged as the lead project manager on our engagements, but also perform Application Lifecycle Management (ALM) assessments for development organizations as well as augment the Technical Evangelists for Microsoft and perform many Team Foundation Server (TFS) demos, installs and “get started” engagements. I have spoken at the New England Code Camp, our most recent CodeMastery event in Boston, and have written several whitepapers.   I am looking forward to helping you “Put down the code.” John Doucette

• 24HOP gets off to a good start

  - by Rob Farley

  Session 11 is on as I write this – Ami Levin presenting about Primary Keys. It’s a good session. But actually, they’ve all been excellent so far, not just Ami’s. I’ve heard only good things about the content. So if you’re reading this and 24HOP is still on, then tune in and take part. If it’s finished, get yourself over to http://sqlpass.org/24hours and see if the sessions have been made available on-demand. Yes – you should be able to watch the sessions when you want to for a year. Watching live is best, because you can ask questions and have them answered during the session, but if there are ones you just couldn’t make, then watching them on-demand is a good option. Numbers have been “not bad”. At the moment it’s still the middle of the night for most Americans – about 6:30am in New York, and yet we’ve had well over a hundred at all the sessions so far, getting up to well over 300 for some sessions. And when I look through the list of names, I see a bunch of names that suggest we’re reaching people from all around the world. I’m seriously looking forward to seeing the stats about which countries have been represented in the audiences. There have been a few comments about the platform. Everyone seems to consider IBTalk an improvement on LiveMeeting, but the closed captioning has met a mixed reception. Some people are loving it, whereas other people are finding the translations leave quite a bit of space for improvement. If you have feedback on this, please feel free to drop me an email (my name with an underscore at hotmail.com, or with a dot at sqlpass.org should reach me just fine, or Twitter, etc). I don’t know how many of the sessions I’ll get to watch overnight – but I’m looking forward to seeing how things go as the day progresses. Big thanks to everyone who’s involved – the sponsors, PASS HQ team and the IBTalk folk who have stayed up overnight to facilitate, plus the moderators, the people doing the live captioning, and of course the speakers and attendees. I love how the SQL Community gets behind things like this. Earlier, the Adelaide SQL Server User Group gathered and watched Denny Lee’s session on BigData, and everyone in the group agreed that it worked really well. I took a picture of our cinema room, although you could only see a small section of the audience. @rob_farley

• My program at #MIX10

  - by Laurent Bugnion

  Getting ready to fly to Vegas and MIX10 is really an exciting time! It is also a very busy time, because we are working on a few projects that will be shown on stage, I have my presentation to prepare, and of course as always the book… though these days it has been a bit on the back burner to be honest ;) I arrive in Vegas on Sunday evening around 10PM, so I won’t be able to make it to the traditional IdentityMine dinner this year. I am sure it will be fun nonetheless! My session: Understanding the MVVM pattern http://live.visitmix.com/MIX10/Sessions/EX14 My session is scheduled on the first day, which is awesome, so I am crossing my fingers and hoping that the MIX team doesn’t change it at the last minute… The session will take place on Monday, the 15th of March, 2PM, Room Lagoon F Important: remember that the USA are moving to Summer time on Sunday, so don’t forget to adjust your watches!! Ask the Experts On Monday evening, I will attend the Ask the Experts event, which is taking place between 5Pm and 6:30PM in the main meal hall. This will be a great occasion to grab a beer and talk about code. The Commons MIX has a great place called the Commons, a great location to chill between sessions, and meet tons of interesting people. I love the Commons and plan to spend a lot of time there to meet as many people as I can. Parties I was invited to a few parties, and will do my best to avoid conflicts :) I plan to be at the following events: Silverlight Mixers on Monday evening Insiders MIX party on Tuesday Silverlight partner happy hour on Tuesday too This is a lot of fun, but at the same time we all know that the best value of a conference is to meet people face to face. This is just the right occasion.  And on Thursday… On Thursday I will be attending a Silverlight event at the Luxor. It will be a very busy day, perfect way to end the conference. I fly back home on Friday morning, but due to a long stop in Washington DC (where I intend to go downtown and take pictures… except if the weather is bad, in which case I will probably go to the museum of flight), I will reach home only on Sunday. Getting hold of me The best way to reach me during MIX is to send me a message on Twitter. I will regularly tweet my location at the conference, so make sure to come and meet me. I am eager to make new friends, to talk about the fantastic jobs we did in WPF and Silverlight over the past year and hear your war stories! http://www.twitter.com/lbugnion   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

• NFS server generating "invalid extent" on EXT4 system disk?

  - by Stephen Winnall

  I have a server running Xen 4.1 with Oneiric in the dom0 and each of the 4 domUs. The system disks of the domUs are LVM2 volumes built on top of an mdadm RAID1. All the domU system disks are EXT4 and are created using snapshots of the same original template. 3 of them run perfectly, but one (called s-ub-02) keeps on being remounted read-only. A subsequent e2fsck results in a single "invalid extent" diagnosis: e2fsck 1.41.14 (22-Dec-2010) /dev/domu/s-ub-02-root contains a file system with errors, check forced. Pass 1: Checking inodes, blocks, and sizes Inode 525418 has an invalid extent (logical block 8959, invalid physical block 0, len 0) Clear<y>? yes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information /dev/domu/s-ub-02-root: 77757/655360 files (0.3% non-contiguous), 360592/2621440 blocks The console shows typically the following errors for the system disk (xvda2): [101980.903416] EXT4-fs error (device xvda2): ext4_ext_find_extent:732: inode #525418: comm apt-get: bad header/extent: invalid extent entries - magic f30a, entries 12, max 340(340), depth 0(0) [101980.903473] EXT4-fs (xvda2): Remounting filesystem read-only I have created new versions of the system disk. The same thing always happens. This, and the fact that the disk is ultimately on a RAID1, leads me to preclude a hardware disk error. The only obvious distinguishing feature of this domU is the presence of nfs-kernel-server, so I suspect that. Its exports file looks like this: /exports/users 192.168.0.0/255.255.248.0(rw,sync,no_subtree_check) /exports/media/music 192.168.0.0/255.255.248.0(rw,sync,no_subtree_check) /exports/media/pictures 192.168.0.0/255.255.248.0(rw,sync,no_subtree_check) /exports/opt 192.168.0.0/255.255.248.0(rw,sync,no_subtree_check) /exports/users and /exports/opt are LVM2 volumes from the same volume group as the system disk. /exports/media is an EXT2 volume. (There is an issue where clients see /exports/media/pictures as being a read-only volume, which I mention for completeness.) With the exception of the read-only problem, the NFS server appears to work correctly under light load for several hours before the "invalid extent" problem occurs. There are no helpful entries in /var/log. All of a sudden, no more files are written, so you can see when the disk was remounted read-only, but there is no indication of what the cause might be. Can anyone help me with this problem? Steve

• Tales of a corrupt SQL log

  - by guybarrette

  Warning: I’m a simple dev, not an all powerful DBA with godly powers. This morning, one of my sites was down and DNN reported a problem with the database.  A quick series of tests revealed that the culprit was a corrupted log file. Easy fix I said, I have daily backups so it’s just a mater of restoring a good copy of the database and log files.  Well, I found out that’s not exactly true.  You see, for this database, I have daily file backups and these are not database backups created by SQL Server. So I restored a set of files from a couple of days ago, stopped the SQL service, copied the files over the bad ones, restarted the service only to find out that SQL doesn’t like when you do that.  It suspects something fishy and marks the database as suspect.  A database marked as suspect can’t be accessed at all.  So now what? I searched throughout the tubes of the InterWeb and found that you can restore from a corrupted log file by creating a new database with the same name as the defective one, then copy the restored database file (the one with data) over the newly created one.  Sweet!  But you still end up with SQL marking the database as suspect but at least, the newly created log is OK.  Well not true, it’s not corrupted but the lack of data makes it not OK for SQL so you need to rebuild the log.  How can you do that when SQL blocks any action the database?  First, you need to change the database status from suspect to emergency.  Then you need to set the database for single access only.  After that, you need to repair the log with DBCC and do the DBA dance.  If you dance long enough, SQL should repair the log file.  Now you need to set the access back to multi user.  Here’s the T-SQL script: use master GO EXEC sp_resetstatus 'MyDatabase' ALTER DATABASE MyDatabase SET EMERGENCY Alter database MyDatabase set Single_User DBCC checkdb('MyDatabase') ALTER DATABASE MyDatabase SET SINGLE_USER WITH ROLLBACK IMMEDIATE DBCC CheckDB ('MyDatabase', REPAIR_ALLOW_DATA_LOSS) ALTER DATABASE MyDatabase SET MULTI_USER So I guess that I would have been a lot easier to restore a SQL backup.  I can’t really say but the InterWeb seems to say so.  Anyway, lessons learned: Vive la différence: File backups are different then SQL backups. Don’t touch me: SQL doesn’t like when you restore a file over a corrupted one. The more the merrier: You should do both SQL and file backups. WTF?: The InterWeb provides you with dozens of way to deal with the problem but many are SQL 2000 or SQL 2005 only, many are confusing and many are written in strange dialects only DBAs understand. var addthis_pub="guybarrette";

• Database Mirroring – deprecated

  - by fatherjack

  Do you use mirroring on any of your databases? Do you use mirroring on SQL Server Standard Edition? I do, as a way of having a stand-by server ready to take over if there is a problem with the live server so that business can continue despite whatever disaster may strike at our primary server location. In my experience it has been a great solution for us as it is simple to implement, reliable and predictable. Mirroring has been around since SQL Server 2005 sp1 but with the release of SQL Server 2012 mirroring has now been placed on the deprecation list. That’s right, Microsoft are removing this feature from SQL Server. SQL Server 2012 had lots of improvements and new features around this sort of technology – the High Availability, Disaster recovery and Always On features described in detail here by Brent Ozar and  Microsoft’s own Customer Service and Support SQL Server Engineers . Now the bad news, the HADRON features are pretty much all wrapped up in the Enterprise Edition of SQL Server 2012. This is going to be a big issue for people, like me, who are only on Standard Edition of earlier versions mostly due to our requirements and the budget (or lack thereof) required for Enterprise Edition licenses. No mirroring in Standard Edition means no upgrade. Don’t Panic. There are two stages of deprecation and they dont happen fast. The first stage – Deprecation Announcement- means that Microsoft have decided that there is a limited future for a particular feature and this is your cue that new projects and developments should not be implemented on this technology as it will cease to exist in the future. This is where mirroring currently stands. You have time to consider your options and start work on planning how you will move away from using this feature. This can be 2 or 3 versions of SQL Server, possibly more. The next stage is Deprecation Final Support - this is where you are on your last chance, When you see this then the next version of SQL Server will not have this feature in it so you need to implement your plans to move to an alternative solution. While these two phases are taking place Microsoft are open to feedback on how people use their products and if enough people make the case for mirroring (or an equivalent technology) to be in the Standard Edition then they may make changes rather than lose customers or have customers cease upgrading in order to keep the functionality they need. Denny Cherry (@MrDenny) has published an article on this same topic here with more detail than me so I wont go over old ground. All I will say is that you should read his article now and then follow the link to his own site where he is collecting peoples information on how they use mirroring in Standard Edition so that our voice can be put to Microsoft.

• Failing report subscriptions

  - by DavidWimbush

  We had an interesting problem while I was on holiday. (Why doesn't this stuff ever happen when I'm there?) The sysadmin upgraded our Exchange server to Exchange 2010 and everone's subscriptions stopped. My Subscriptions showed an error message saying that the email address of one of the recipients is invalid. When you create a subscription, Reporting puts your Windows user name into the To field and most users have no permissions to edit it. By default, Reporting leaves it up to exchange to resolve that into an email address. This only works if Exchange is set up to translate aliases or 'short names' into email addresses. It turns out this leaves Exchange open to being used as a relay so it is disabled out of the box. You now have three options: Open up Exchange. That would be bad. Give all Reporting users the ability to edit the To field in a subscription. a) They shouldn't have to, it should just work. b) They don't really have any business subscribing anyone but themselves. Fix the report server to add the domain. This looks like the right choice and it works for us. See below for details. Pre-requisites: A single email domain name. A clear relationship between the Windows user name and the email address. eg. If the user name is joebloggs, then joebloggs@domainname needs to be the email address or an alias of it. Warning: Saving changes to the rsreportserver.config file will restart the Report Server service which effectively takes Reporting down for around 30 seconds. Time your action accordingly. Edit the file rsreportserver.config (most probably in the folder ..\Program Files[ (x86)]\Microsoft SQL Server\MSRS10_50[.instancename]\Reporting Services\ReportServer). There's a setting called DefaultHostName which is empty by default. Enter your email domain name without the leading '@'. Save the file. This domain name will be appended to any destination addresses that don't have a domain name of their own.

• How To Deal With Terrible Design Decisions

  - by splatto

  I'm a consultant at one company. There is another consultant who is a year older than me and has been here 3 months longer than I have, and a full time developer. The full-time developer is great. My concern is that I see the consultant making absolutely terrible design decisions. For example, M:M relationships are being stored in the database as a comma-delimited string rather than using a conjunction table to hold the relationships. For example, consider two tables, Car and Property: Car records: Camry Volvo Mercedes Property records: Spare Tire Satellite Radio Ipod Support Standard Rather than making a table CarProperties to represent this, he has made a "Property" attribute on the Car table whose data looks like "1,3,7,13,19,25," I hate how this decision and others are affecting the quality of my code. We have butted heads over this design three times in the past two months since I've been here. He asked me why my suggestion was better, and I responded that our database would be eliminating redundant data by converting to a higher normal form. I explained that this design flaw in particular is discussed and discouraged in entry level college programs, and he responded with a shot at me saying that these comma-separated-value database properties are taught when you do your masters (which neither of us have). Needless to say, he became very upset and demanded I apologize for criticizing his work, which I did in the interest of not wanting to be the consultant to create office drama. Our project manager is focused on delivering a product ASAP and is a very strong personality - Suggesting to him at this point that we spend some time to do this right will set him off. There is a strong likelihood that both of our contracts will be extended to work on a second project coming up. How will I be able to exert dominant influence over the design of the system and the data model to ensure that such terrible mistakes are not repeated in the next project? A glimpse at the dynamics: I can be a strong personality if I don't measure myself. The other consultant is not a strong personality, is a poor communicator, is quite stubborn and thinks he is better than everyone else. The project manager is an extremely strong personality who is focused on releasing tomorrow's product yesterday. The full-time developer is very laid back and easy going, a very effective communicator, but is someone who will accept bad design if it means not rocking the boat. Code reviews or anything else that takes "time" will be out of the question - there is no way our PM will be sold on such a thing by anybody.

• Outlying DBAs

  - by steveh99999

  Read an interesting book recently, ‘Outliers – the story of success’ by Malcolm Gladwell. There’s a good synopsis of the book here on wikipedia. I don’t want to write in detailed review of the book, but it’s well worth a read. There were a couple of sections which I thought were possibly relevant to IT professionals and DBAs in particular. Firstly, ‘the 10,000 hour rule’, in this section Gladwell asserts that to be a real ‘elite performer’ takes 10,000 hours of practice. ‘Practice isn’t the thing you do once you’re good, it’s the thing you do that makes you good’.  He gives many interesting examples – the Beatles, Bill Gates etc – but I was wondering could this be applied to DBAs ? If it takes 10,000 hours to be a really elite DBA – how long does that really take ? 8 hours a day makes 1250 days. If we assume that most DBAs work around 230 days a year – then it takes around 5 and a half years to become an elite DBA.   But how much time per day does a DBA spend actually doing DBA work ? Certainly it’s my experience that the more experienced I get as a DBA, the less time I seem to spend actually doing DBA work – ie meetings, change-control meetings, project planning, liasing with other teams, appraisals etc.  Is it more accurate to assume that a DBA spends half their time actually doing ‘real’ DBA work – or is that just my bad luck ?   So, in reality, I’d argue it can take at least 5 1/2 and more likely closer to 10 years to become an elite DBA. Why do I keep receiving CVs for senior DBAs with 2-4 years actual DBA experience ? In the second section I found particularly interesting, Gladwell writes about analysis of plane crashes and the importance of in-cockpit communications. He describes a couple of crashes involving Korean Airlines – where co-pilots were often deferrential to pilots, and unwilling to openly criticise their more senior colleagues or point out errors when things were going badly wrong… There’s a better summary of Gladwell’s concepts on mitigation  here – but to apply this to a DBA role… If you are a DBA and you do not agree with  a decision of one of your superiors, then it’s your duty as a DBA to say what you think is wrong, before it’s too late…  Obviously there’s a fine line between constructive criticism and moaning, but a good senior DBA or manager should be able to take well-researched criticism\debate from a more junior DBA.   Is this really possible ?

• JUDCon 2013 Trip Report

  - by reza_rahman

  JUDCon (JBoss Users and Developers Conference) 2013 was held in historic Boston on June 9-11 at the Hynes Convention Center. JUDCon is the largest get together for the JBoss community, has gone global in recent years but has it's roots in Boston. The JBoss folks graciously accepted a Java EE 7 talk from me and actually referenced my talk in their own sessions. I am proud to say this is my third time speaking at JUDCon/the Red Hat Summit over the years (this was the first time on behalf of Oracle). I had great company with many of the rock stars of the JBoss ecosystem speaking such as Lincoln Baxter, Jay Balunas, Gavin King, Mark Proctor, Andrew Lee Rubinger, Emmanuel Bernard and Pete Muir. Notably missing from JUDCon were Bill Burke, Burr Sutter, Aslak Knutsen and Dan Allen. Topics included Java EE, Forge, Arquillian, AeroGear, OpenShift, WildFly, Errai/GWT, NoSQL, Drools, jBPM, OpenJDK, Apache Camel and JBoss Tools/Eclipse. My session titled "JavaEE.Next(): Java EE 7, 8, and Beyond" went very well and it was a full house. This is our main talk covering the changes in JMS 2, the Java API for WebSocket (JSR 356), the Java API for JSON Processing (JSON-P), JAX-RS 2, JPA 2.1, JTA 1.2, JSF 2.2, Java Batch, Bean Validation 1.1, Java EE Concurrency and the rest of the APIs in Java EE 7. I also briefly talked about the possibilities for Java EE 8. The slides for the talk are here: JavaEE.Next(): Java EE 7, 8, and Beyond from reza_rahman Besides presenting my talk, it was great to catch up with the JBoss gang and attend a few interesting sessions. On Sunday night I went to one of my favorite hangouts in Boston - the exalted Middle East Club as Rolling Stone refers to it (other cool spots in an otherwise pretty boring town is "the Church"). As contradictory as it might sound to the uninitiated, the Middle East Club is possibly the best place in Boston to simultaneously get great Middle Eastern (primarily Lebanese) food and great underground metal. For folks with a bit more exposure, this is probably not contradictory at all given bands like Acrassicauda and documentaries like Heavy Metal in Baghdad. Luckily for me they were featuring a few local Thrash metal bands from the greater Boston area. It wasn't too bad considering it was primarily amateur twenty-something guys (although I'm not sure I'm a qualified critic any more since I all but stopped playing about at that age). It's great Boston has the Middle East as an incubator to keep the rock, metal, folk, jazz, blues and indie scene alive. I definitely enjoyed JUDCon/Boston and hope to be part of the conference next year again.

• Questions about game states

  - by MrPlow

  I'm trying to make a framework for a game I've wanted to do for quite a while. The first thing that I decided to implement was a state system for game states. When my "original" idea of having a doubly linked list of game states failed I found This blog and liked the idea of a stack based game state manager. However there were a few things I found weird: Instead of RAII two class methods are used to initialize and destroy the state Every game state class is a singleton(and singletons are bad aren't they?) Every GameState object is static So I took the idea and altered a few things and got this: GameState.h class GameState { private: bool m_paused; protected: StateManager& m_manager; public: GameState(StateManager& manager) : m_manager(manager), m_paused(false){} virtual ~GameState() {} virtual void update() = 0; virtual void draw() = 0; virtual void handleEvents() = 0; void pause() { m_paused = true; } void resume() { m_paused = false; } void changeState(std::unique_ptr<GameState> state) { m_manager.changeState(std::move(state)); } }; StateManager.h class GameState; class StateManager { private: std::vector< std::unique_ptr<GameState> > m_gameStates; public: StateManager(); void changeState(std::unique_ptr<GameState> state); void StateManager::pushState(std::unique_ptr<GameState> state); void popState(); void update(); void draw(); void handleEvents(); }; StateManager.cpp StateManager::StateManager() {} void StateManager::changeState( std::unique_ptr<GameState> state ) { if(!m_gameStates.empty()) { m_gameStates.pop_back(); } m_gameStates.push_back( std::move(state) ); } void StateManager::pushState(std::unique_ptr<GameState> state) { if(!m_gameStates.empty()) { m_gameStates.back()->pause(); } m_gameStates.push_back( std::move(state) ); } void StateManager::popState() { if(!m_gameStates.empty()) m_gameStates.pop_back(); } void StateManager::update() { if(!m_gameStates.empty()) m_gameStates.back()->update(); } void StateManager::draw() { if(!m_gameStates.empty()) m_gameStates.back()->draw(); } void StateManager::handleEvents() { if(!m_gameStates.empty()) m_gameStates.back()->handleEvents(); } And it's used like this: main.cpp StateManager states; states.changeState( std::unique_ptr<GameState>(new GameStateIntro(states)) ); while(gamewindow::gameWindow.isOpen()) { states.handleEvents(); states.update(); states.draw(); } Constructors/Destructors are used to create/destroy states instead of specialized class methods, state objects are no longer static but

• GNU/Linux interactive table content GUI editor?

  - by sdaau

  I often find myself in the need to gather data (say from the internet), into a table, for comparison reasons. I usually need the final table output in HTML or MediaWiki mostly, but often times also Latex. My biggest problem is that I often forget the correct table syntax for these markup languages, as well as what needs to be properly escaped in the inline data, for the table to render correctly. So, I often wish there was a GUI application, which provides a tabular framework - which I could stick "Always on Top" as a desktop window, and I could paste content into specific cells - before finally exporting the table as a code in the correct language. One application that partially allows this is Open/LibreOffice calc: The good thing here is that: I can drag and drop browser content into a specifically targeted table cell (here B2) "Rich" text / HTML code gets pasted For long content, the cell (column) width stays put as it originally was The bad thing is, that: when the cell height (due to content size) becomes larger than the calc window, it becomes nearly impossible to scroll calc contents up and down (at least with the mousewheel), as the view gets reset to top-right corner of the selected cell calc shows an "endless"/unlimited field of cells, so not exactly a "table" - which I find visually very confusing (and cognitively taxing) Can only export table to HTML What I would need is an application that: Allows for a limited size table, but with quick adding of rows and columns (e.g. via corresponding + buttons) Allows for quick setup of row and column height and width (as well as table size) Stays put at those sizes, regardless of size of content pasted in; if cell content overflows, cell scrollbars are shown (cell content could be possibly re-edited in a separate/new window); if table overflows over window size, window scrollbars are shown Exports table in multiple formats (I'd need both HTML and mediawiki), properly escaping cell content for each (possibility to strip HTML tags from content pasted in cells, to get plain text, is a plus) Targeting a specific cell in the table for the content paste operation is a must - it doesn't have to be drag'n'drop though, a right click over a cell with "Paste content" is enough. I'd also want the ability to click in a specific cell and type in (plain text) content immediately. So, my question is: is there an application out there that already does something like this? The reason I'm asking is that - as the screenshots show - for instance Libre/OpenOffice allows it, but only somewhat (as using it for that purpose is tedious). I know there exist some GUI editors for Linux (both for UI like guile or HTML like amaya); but I don't know them enough to pinpoint if any of them would offer this kind of functionality (and at least in my searches, that kind of functionality, if present in diverse software, seems not to be advertised). Note I'm not interested in styling an HTML table, which is why I haven't used "table designer" in the title, but "table editor" (in lack of better terms) - I'm interested in (quickly) adjusting row/column size of the table, and populating it with pasted data (which is possibly HTML) in a GUI; and finally exporting such a table as self-contained HTML (or other) code.

• URL protocol handlers in basic Ubuntu Desktop

  - by Hibou57

  There was a way to register URL protocol handlers with Gconf, which is now obsolete and there seems to be no way to do the same with DConf (or Gsettings, its recommended wrapper). How do one properly register an URL protocol handlers since DConf? Additionally, something looks strange to me (as I don't understand it), on my Ubuntu 12.04 The protocol apt:// should be handled by the apturl command. It is so with my Opera browser, but only because I added this specific association using the browser's configuration facility. Otherwise, in the rest of the environment: Running xdg-open apt://foo.bar opens elinks (my www-browser alternative). Running gnome-open apt://foo.bar opens the Software?Center. Opening gcong-editor, I see a key /desktop/gnome/url-handlers/apt whose value is apturl "%s" and its enable. This configuration seems to be ignored, which is reasonably expected, as GConf is considered obsolete. Opening dconf-editor, I can't see anything related to URL handlers or protocols in /desktop/gnome It looks a bit messy to my eyes (just teasing with this wording, nothing bad) What's underneath? Side note: I'm looking for something which preferably works even when the full desktop environment is not loaded, like when running an i3wm session with only gsettings-daemon (and other stuffs unrelated to this case) is loaded. Update Another way to “register” a protocol handler is with *.desktop files and their MIME-Type; ex. MimeType=application/<the-protocol>;. I found a /usr/share/applications/ubuntu-software-center.desktop with this content: [Desktop Entry] Name=Ubuntu Software Center GenericName=Software Center Comment=Lets you choose from thousands of applications available for Ubuntu Exec=/usr/bin/software-center %u Icon=softwarecenter Terminal=false Type=Application Categories=PackageManager;GTK;System;Settings; MimeType=application/x-deb;application/x-debian-package;x-scheme-handler/apt; StartupNotify=true X-Ubuntu-Gettext-Domain=software-center Keywords=Sources;PPA;Install;Uninstall;Remove;Purchase;Catalogue;Store; This one explains why gnome-open apt://foo.bar opens the Software?Center instead of apturl. So I installed this apturl.desktop in ~/.local/share/applications: [Desktop Entry] Encoding=UTF-8 Version=1.0 Type=Application Terminal=false Exec=/usr/bin/apturl %u Name=APT-URL Comment=APT-URL handler Icon= Categories=Application;Network; MimeType=x-scheme-handler/apt; After update-desktop-database and even after rebooting, both xdg-open and gnome-open still do the same and ignore this user desktop file, which is usual, should override the other in /usr/share/applications/. May be there is something special with desktop files specifying x-scheme-handler MIME type and they are not handled the usual way. The desktop-file way does not answer the question.
