• Is my computer slow due to lack of swap

  - by Kristian Jensen

  A few months ago, I installed Ubuntu 12.04 alongside with Windows 7 on my Asus EEE-PC 1015bx. It has a tendency of freezing and when trying to investigate I found that a swap partition of only 256 MB had been created. The Asus EEE-PC 1015bx is born with 1 GByte RAM only and it is not possible to add further or exchange the existing 1 GByte with a larger card. When looking at the system monitor, it looks like all swap is being utilized along with 70-75% of the RAM, even with very few applications running. Can the lack of much swap space be the reason for my computer running slowly and at times freezing? How can I add a swap partition? Or should I add a swap file instead? At the moment, I see two partitions when viewing the system monitor: one 28.6 GByte ext4 partition which must be the one containing Ubuntu and one 100 GByte fuseblk partition which I assume is the one holding Windows. It shows that I have 18.6 GByte free space on the ext4 partition. Can I "take a bite" from the ext4 partition and convert this into a swap partition? I was thinking something like 3 GBytes for swap considering my limited RAM. I hope that someone can guide me through. Thank you. 20th Oct 2012 - Further details Thank you for below answer which I find very useful. I am certainly considering switching to one of your suggested shells as I can see from the Internet that many have posted that these require much fewer resources than ubuntu. It seems to me that lubuntu is the perfect match for my very limited computer. I will have to wait a few days, though, as I am presently limited by a very slow and restricted Internet connection via satellite. But will lubuntu install as simply another shell replacing unity or will it replace ubuntu all together? Will the software that I have installed under ubuntu still be accessible in lubuntu? And can I return to ubuntu if required? Regarding the actual question of swap: When I run gparted, it shows me that there is one ntfs partition of 100 GBytes from where it boots and the before mentioned ext4 partition of 28.6 GBytes is not mentioned. Could it be that my ubuntu installation resides inside this 100 GBytes ntfs partiotion? And if so, can I take a bite of this for my swap partition? Realising that gparted is shown in Danish, I hope that you can make out what I mean. System monitoring shows below details: Once again I sincerely hope that you can help. Thank you.

• Achieving Zero Downtime Deployment

  - by MattW

  I am trying to achieve zero downtime deployments so I can deploy less during off hours and more during "slower" hours - or anytime, in theory. My current setup, somewhat simplified: Web Server A (.NET App) Web Server B (.NET App) Database Server (SQL Server) My current deployment process: "Stop" the sites on both Web Server A and B Upgrade the database schema for the version of the app being deployed Update Web Server A Update Web Server B Bring everything back online Current Problem This leads to a small amount of downtime each month - about 30 mins. I do this during off hours, so it isn't a huge problem - but it is something I'd like to get away from. Also - there is no way to really go 'back'. I don't generally make rollback DB scripts - only upgrade scripts. Leveraging The Load Balancer I'd love to be able to upgrade one Web Server at a time. Take Web Server A out of the load balancer, upgrade it, put it back online, then repeat for Web Server B. The problem is the database. Each version of my software will need to execute against a different version of the database - so I am sort of "stuck". Possible Solution A current solution I am considering is adopting the following rules: Never delete a database table. Never delete a database column. Never rename a database column. Never reorder a column. Every stored procedure must be versioned. Meaning - 'spFindAllThings' will become 'spFindAllThings_2' when it is edited. Then it becomes 'spFindAllThings_3' when edited again. Same rule applies to views. While, this seems a bit extreme - I think it solves the problem. Each version of the application will be hitting the DB in a non breaking way. The code expects certain results from the views/stored procedures - and this keeps that 'contract' valid. The problem is - it just seeps sloppy. I know I can clean up old stored procedures after the app is deployed for awhile, but it just feels dirty. Also - it depends on all of the developers following these rule, which will mostly happen, but I imagine someone will make a mistake. Finally - My Question Is this sloppy or hacky? Is anybody else doing it this way? How are other people solving this problem?

• What's your advise on a potential legal suit? [closed]

  - by ohho

  I [xxx app developer] received an email from Apple that a developer [of yyy app] believes I am "infringing their copyright." Description of Issue: [xxx developer] copied my application (my application is [yyy]) feature by feature. Even their donation model is completely copied from my application. Their first release was significantly later than mine, which implies copying of the application rather than parallel development. I suffered significant financial losses because of their actions, in additional to promotion problems as many people are confused with their product. My advertising was based around the idea of a "free [yyy] application for an iPhone" and they have just taken that as a title for their application. I would appreciate if someone takes a look at their release schedule and compare it to my releases. Additionally, please take a look at their functionality and how it point by point copies the functionality of my older releases. I am asking Apple to remove their application from the App Store, and ban them from resubmitting it. Thank you for your time! [yyy developer], the developer of the [yyy] application. My response was: The code of [xxx] is written by myself, using Apple public API. The graphics elements are designed by myself. The user interface and app control are independently designed and different from other [similar type] apps (please judge yourself). In-app Purchase is iOS Apple standard API. iAd is Apple iOS standard API. I don't think features can be owned exclusively. In fact, my app comes with fewer features, as I prefer minimalist design. I don't think idea can be owned exclusively. Apple responded: Thank you for your response. Unfortunately, Apple cannot serve as arbiter for disputes among third parties. Please contact [yyy developer] directly regarding your actions. You can reach [yyy developer] through: [...]. We look forward to confirmation from both parties that this issue has been resolved. If this issue is not resolved shortly, Apple may be forced to pull your application(s) from the App Store. Then I sent my response above to [yyy developer]. [yyy developer] then asked me "to provide (my) legal address and contact details that (his) lawyer requires to file a copyright infringement suit." IMO, I don't think the [yyy developer]'s claim on "feature by feature" copy is valid. I have fewer features, completely different user interface design. However, I don't think I can afford a legal action for an app of so little financial return. So what's your advise on this? Should I just let Apple pull my app? Or is there any alternative I can consider? FYI ... UI of [xxx app]: and UI of [yyy app]:

• Au revoir, Python?

  - by GuySmiley

  I'm an ex-C++ programmer who's recently discovered (and fallen head-over-heels with) Python. I've taken some time to become reasonably fluent in Python, but I've encountered some troubling realities that may lead me to drop it as my language of choice, at least for the time being. I'm writing this in the hopes that someone out there can talk me out of it by convincing me that my concerns are easily circumvented within the bounds of the python universe. I picked up python while looking for a single flexible language that will allow me to build end-to-end working systems quickly on a variety of platforms. These include: - web services - mobile apps - cross-platform client apps for PC Development speed is more of a priority at the time-being than execution speed. However, in order to improve performance over time without requiring major re-writes or architectural changes I think it's imperative to be able to interface easily with Java. That way, I can use Java to optimize specific components as the application scales, without throwing away any code. As far as I can tell, my requirement for an enterprise-capable, platform-independent, fast language with a large developer base means it would have to be Java. .NET or C++ would not cut it due to their respective limitations. Also Java is clearly de rigeur for most mobile platforms. Unfortunately, tragically, there doesn't seem to be a good way to meet all these demands. Jython seems to be what I'm looking for in principle, except that it appears to be practically dead, with no one developing, supporting, or using it to any great degree. And also Jython seems too married to the Java libraries, as you can't use many of the CPython standard libraries with it, which has a major impact on the code you end up writing. The only other option that I can see is to use JPype wrapped in marshalling classes, which may work although it seems like a pain and I wonder if it would be worth it in the long run. On the other hand, everything I'm looking for seems to be readily available by using JRuby, which seems to be much better supported. As things stand, I think this is my best option. I'm sad about this because I absolutely love everything about Python, including the syntax. The perl-like constructs in Ruby just feel like such a step backwards to me in terms of readability, but at the end of the day most of the benefits of python are available in Ruby as well. So I ask you - am I missing something here? Much of what I've said is based on what I've read, so is this summary of the current landscape accurate, or is there some magical solution to the Python-Java divide that will snuff these concerns and allow me to comfortably stay in my happy Python place?

• Is inline SQL still classed as bad practice now that we have Micro ORMs?

  - by Grofit

  This is a bit of an open ended question but I wanted some opinions, as I grew up in a world where inline SQL scripts were the norm, then we were all made very aware of SQL injection based issues, and how fragile the sql was when doing string manipulations all over the place. Then came the dawn of the ORM where you were explaining the query to the ORM and letting it generate its own SQL, which in a lot of cases was not optimal but was safe and easy. Another good thing about ORMs or database abstraction layers were that the SQL was generated with its database engine in mind, so I could use Hibernate/Nhibernate with MSSQL, MYSQL and my code never changed it was just a configuration detail. Now fast forward to current day, where Micro ORMs seem to be winning over more developers I was wondering why we have seemingly taken a U-Turn on the whole in-line sql subject. I must admit I do like the idea of no ORM config files and being able to write my query in a more optimal manner but it feels like I am opening myself back up to the old vulnerabilities such as SQL injection and I am also tying myself to one database engine so if I want my software to support multiple database engines I would need to do some more string hackery which seems to then start to make code unreadable and more fragile. (Just before someone mentions it I know you can use parameter based arguments with most micro orms which offers protection in most cases from sql injection) So what are peoples opinions on this sort of thing? I am using Dapper as my Micro ORM in this instance and NHibernate as my regular ORM in this scenario, however most in each field are quite similar. What I term as inline sql is SQL strings within source code. There used to be design debates over SQL strings in source code detracting from the fundamental intent of the logic, which is why statically typed linq style queries became so popular its still just 1 language, but with lets say C# and Sql in one page you have 2 languages intermingled in your raw source code now. Just to clarify, the SQL injection is just one of the known issues with using sql strings, I already mention you can stop this from happening with parameter based queries, however I highlight other issues with having SQL queries ingrained in your source code, such as the lack of DB Vendor abstraction as well as losing any level of compile time error capturing on string based queries, these are all issues which we managed to side step with the dawn of ORMs with their higher level querying functionality, such as HQL or LINQ etc (not all of the issues but most of them). So I am less focused on the individual highlighted issues and more the bigger picture of is it now becoming more acceptable to have SQL strings directly in your source code again, as most Micro ORMs use this mechanism. Here is a similar question which has a few different view points, although is more about the inline sql without the micro orm context: http://stackoverflow.com/questions/5303746/is-inline-sql-hard-coding

• My Package Version Number Appears Greater Yet apt-get Doesn't Select It

  - by nutznboltz

  Backstory: It was determined that when using lxc container VMs the Nagios nrpe shutdown script when run on the host of the containers would kill the nrpe processes inside the containers. This was remediated by changing the script to use pidfiles instead of searching the process table for the nrpe process. Regrettably start-stop-daemon is a C program that resulted from translating a Perl script and it shows. There are far too many global varibles in start-stop-daemon.c and although there are some nice blocks of comments there are far to few comments that explain the intent behind variable names such as "schedule" (the string "schedule" appears in many contexts.) The manual page for start-stop-daemon strongly suggests that unless you use the "--retry" option the start-stop-daemon program may return before the process it sent a signal to actually calls exit() and terminates, however it doesn't actually state this in plain English. The obtuseness of start-stop-daemon is most likely the reason that the "fixed" version of the script includes a dubious comment indicating that sometimes the pid file has not been removed. I can easily see why someone would not understand that he left the --retry option missing. This bug also causes failures when the script is given the "restart" option; the nrpe daemon will shutdown but not start up again. Did I mention that since applying the update our nrpe servers started crashing over and over? Repairing this is why I am doing this work. I have been working on remediating the fix. You can see my current work in this PPA. Actual Question: The upstream version number of nagios-nrpe-server in lucid-updates is 2.12-4ubuntu1.10.04.1 My PPA uses this version number 2.12-4ubuntu1.10.04.1.1~ppa1~lucid1 I check the rules here and use this test program and I am lead to believe that the version number I use in my PPA is greater than the one in lucid-updates yet when I ran: sudo add-apt-repository ppa:nutznboltz/nrpe-unbreak-lp-600941 sudo apt-get update sudo aptitiude dist-upgrade The replacement package was not installed. I was able to install it using sudo aptitude install nagios-nrpe-server=2.12-4ubuntu1.10.04.1.1~ppa1~lucid1 Can anyone explain this behavior? Why didn't my version number appear greater to "aptitude dist-upgrade"? Thanks $ cat /etc/apt/preferences Package: * Pin: release a=lucid-backports Pin-Priority: 400 Package: * Pin: release a=lucid-security Pin-Priority: 990 Package: * Pin: release a=lucid-updates Pin-Priority: 900 Package: * Pin: release a=lucid-proposed Pin-Priority: 400 $ ls /etc/apt/preferences.d/ $ Should not make any difference as a PPA cannot be in any of those pockets. I went ahead and bumped the version number in the PPA to 2.12-4ubuntu1.10.04.2~ppa1~lucid1. I'll see if that makes a difference. I do notice that lintian complains: W: nagios-nrpe-server: debian-revision-not-well-formed 2.12-4ubuntu1.10.04.2~ppa1~lucid1

• Where are my sub templates?

  - by Tim Dexter

  This one is for standalone/BIEE uses of Publisher. All the ERP/CRM/HCM folks are already catered for and can tuck into a nut cutlet and arugala salad. Sorry, I have just watched Food Inc and even if only half of it is true; Im still on a crusade in my house against mass produced food. Wake up World! If you have ventured into the world of sub templating, you'll be reaping some development benefit. In terms of shared report components and calculations they are very useful. Just exporting all of your report headers and footers to a single sub template can potentially save you hours and hours of work and make you look like a star. If someone in management gets it into their head that they would like Comic San Serif font rather than Arial in their report headers, its a 10 min job rather than 100 hours! What about the rest of the report content? I hear you cry. Its coming in 11g, full master template support. Your management wants bright blue borders with yellow backgrounds for all the tables in your reports, 5 minute job! Getting back to sub templates and my comment about all the ERP/CRM/HCM folks be catered for. In the standalone release there is no out of the box directory for you to drop your sub templates. Dropping them into the main report directory would make sense but they are not accessible there via a URL. An oversight on our part and something that will be addressed in 11g. Sub templates are now a first class citizen in the world of BIP, you can upload them and BIP will know what to do with them. But what do you do right now? The easiest place to put them where BIP can 'see' them is to create a directory under the xmlpserver install directory in the J2EE container e.g. $J2EE_HOME/xmlpserver/xmlpserver/subtemplates You can call it whatever you want but when the server is started up, that directory is accessible via a URL i.e. http://tdexter:9704/xmlpserver/subtemplates/mysub.rtf. You can therefore put it into the top of your main templates and call the sub template. <?import: http://tdexter:9704/xmlpserver/subtemplates/mysub.rtf?> Of course, you can drop them anywhere you want, they just need to be in a web server mountable directory. Enjoy the arugala!

• Best Platform/Engine for turn based Client/Server Android game

  - by Paradine

  I'm currently designing a turn based game for tablets. Initially for Android with porting to iOS later considered in design. I'm having trouble narrowing down the available technologies to even know where to spend my research time. I am hoping that if I explain what I am trying to achieve someone may be able to suggest a platform and/or engine. I've looked into some of the open source Engines ( http://www.cuteandroid.com/ten-open-source-android-2d-or-3d-game-engine-for-android-developers ) and some appear to handle much of what I might require - although with a higher focus on graphics than i need. Mages looks interesting although development appears to have ceased. If I could somehow leverage GoogleApps that would be excellent. Here is what I am trying to achieve: PvP turn based strategy game over internet - minimal animation and bandwidth required Players match up online using MetaGame system MatchID created on Resolution Server and Game starts Clients have 30 second countdown to select MoveString Clients sends small secure timestamped and MatchIDed MoveString to Resolution server Resolution server looks up Move String for each player, Resolves and Updates Players status in MatchID on Server Resolution server updates Client Views Repeat until victory conditions met - MatchID Closed, Rewards earned in MetaGame There will also need to be a full social and account system and metagame backend - but this could be running on separate system(s) Tablet in Offline mode would be catalog browsing and perhaps single player AI - bum I'm focusing on the Resolution Server at this point I'm not even certain if I would be looking at an Android App or a WebApp at this stage! I want a custom GUI so I guess an app - but maybe as I have little animation a WebApp might also work. Probably some combination of both. There will be very small overhead in data between client server - essentially a small text string every 30 seconds sent to the Resolution server which looks up the Effect and applies it to the Opponents string and determines some results to apply to the match. The client view is updated minimally with the results (only 5 in game Integers tracked) - perhaps triggering small animations/popups on the client to show the end result. e.g Explosion. If you have suggestions for a good technology or platform to best achieving the Resolution Server I'd love to hear. Also if you have experience with open source Engines - and could narrow down which (if any ) might be most suitable that would be a big help. Thanks in advance

• Finance: Friends, not foes!

  - by red@work

  After reading Phil's blog post about his experiences of working on reception, I thought I would let everyone in on one of the other customer facing roles at Red Gate... When you think of a Credit Control team, most might imagine money-hungry (and often impolite) people, who will do nothing short of hunting people down until they pay up. Well, as with so many things, not at Red Gate! Here we do things a little bit differently.   Since joining the Licensing, Invoicing and Credit Control team at Red Gate (affectionately nicknamed LICC!), I have found it fantastic to work with people who know that often the best way to get what you want is by being friendly, reasonable and as helpful as possible. The best bit about this is that, because everyone is in a good mood, we have a great working atmosphere! We are definitely a very happy team. We laugh a lot, even when dealing with the serious matter of playing table football after lunch. The most obvious part of my job is bringing in money. There are few things quite as satisfying as receiving a big payment or one that you've been chasing for a long time. That being said, it's just as nice to encounter the companies that surprise you with a payment bang on time after little or no chasing. It's always a pleasure to find these people who are generous and easy to work with, and so they always make me smile, too. As I'm in one of the few customer facing roles here, I get to experience firsthand just how much Red Gate customers love our software and are equally impressed with our customer service. We regularly get replies from people thanking us for our help in resolving a problem or just to simply say that they think we're great. Or, as is often the case, that we 'rock and are awesome'! When those are the kinds of emails you have to deal with for most of the day, I would challenge anyone to be unhappy! The best thing about my work is that, much like Phil and his counterparts on reception, I get to talk to people from all over the world, and experience their unique (and occasionally unusual) personality traits. I deal predominantly with customers in the US, so I'll be speaking to someone from a high flying multi-national in New York one minute, and then the next phone call will be to a small office on the outskirts of Alabama. This level of customer involvement has led to a lot of interesting anecdotes and plenty of in-jokes to keep us amused! Obviously there are customers who are infuriating, like those who simply tell us that they will pay "one day", and that we should stop chasing them. Then there are the people who say that they ordered the tools because they really like them, but they just can't afford to actually pay for them at the moment. Thankfully these situations are relatively few and far between, and for every one customer that makes you want to scream, there are far, far more that make you smile!

• Collision detection - Smooth wall sliding, no bounce effect

  - by Joey

  I'm working on a basic collision detection system that provides point - OBB collision detection. I have around 200 cubes in my environment and I check (for now) each of them in turn and see if it collides. If it does I return the colliding face's normal, save the old player position and do some trigonometry to return a new player position for my wall sliding. edit I'll define my meaning of wall sliding: If a player walks in a vertical slope and has a slight horizontal rotation to the left or the right and keeps walking forward in the wall the player should slide a little to the right/left while continually walking towards the wall till he left the wall. Thus, sliding along the wall. Everything works fine and with multiple objects as well but I still have one problem I can't seem to figure out: smooth wall sliding. In my current implementation sliding along the walls make my player bounce like a mad man (especially noticable with gravity on and moving forward). I have a velocity/direction vector, a normal vector from the collided plane and an old and new player position. First I negate the normal vector and get my new velocity vector by substracting the inverted normal from my direction vector (which is the vector to slide along the wall) and I add this vector to my new Player position and recalculate the direction vector (in case I have multiple collisions). I know I am missing some step but I can't seem to figure it out. Here is my code for the collision detection (run every frame): Vector direction; Vector newPos(camera.GetOriginX(), camera.GetOriginY(), camera.GetOriginZ()); direction = newPos - oldPos; // Direction vector // Check for collision with new position for(int i = 0; i < NUM_OBJECTS; i++) { Vector normal = objects[i].CheckCollision(newPos.x, newPos.y, newPos.z, direction.x, direction.y, direction.z); if(normal != Vector::NullVector()) { // Get inverse normal (direction STRAIGHT INTO wall) Vector invNormal = normal.Negative(); Vector wallDir = direction - invNormal; // We know INTO wall, and DIRECTION to wall. Substract these and you got slide WALL direction newPos = oldPos + wallDir; direction = newPos - oldPos; } } Any help would be greatly appreciated! FIX I eventually got things up and running how they should thanks to Krazy, I'll post the updated code listing in case someone else comes upon this problem! for(int i = 0; i < NUM_OBJECTS; i++) { Vector normal = objects[i].CheckCollision(newPos.x, newPos.y, newPos.z, direction.x, direction.y, direction.z); if(normal != Vector::NullVector()) { Vector invNormal = normal.Negative(); invNormal = invNormal * (direction * normal).Length(); // Change normal to direction's length and normal's axis Vector wallDir = direction - invNormal; newPos = oldPos + wallDir; direction = newPos - oldPos; } }

• What to do if I am working on a language that I don't like

  - by Sayem Ahmed

  Hi there, I really don't know if this is the right place to ask this question, but if it isn't, then I guess someone will notify. Anyway, I am working in a software development farm which is currently using PowerBuilder to develop a mid-size ERP solution. The work environment and company management are so great that it may be the best in the whole Bangladesh. Only problem is the technology that are currently being used, which is this PowerBuilder. Now I am a guy who tends to prefer modern development technologies, like DI containers, ORM, TDD, JQuery etc. PowerBuilder is a great tool too, but I couldn' like the application techniques used to build PB applications. These techniques are so inheritance-dependent that many a times these create a great deal of sufferings. I remember two days ago I had to change some processing logic in a core user object and as a result I had to test and re-test all the forms that the application have(apparently, there are almost 20 forms there, each of them with 3-4 kinds of functionalities). Also, learning PB is tough, because online material on this thing is very, very low. I can't afford to read all the documentation that PB provide because I have hard deadlines on the work that I have to do. Another thing with PB is that applications tend to rely on business logic that are implemented on databases which causes debugging to be a nightmare. As a result, I don't feel motivated enough to work in this IDE/System/Framework (or whatever) anymore. My productivity has greatly decreased, and I am not delivering quality code. I think I have the following options available to me - Remain in the current job, keep delivering worse code and let my productivity decrease day by day, taking salaries and bonuses but not delivering quality codes/doing my job the way I should, Search for a new job. At this point number 2 seems a good option, but there are also some issues. As I mentioned before, our management may be the best in the country. Our company owner is himself a software developer with 24 years of experience in software development. He is currently our Team Leader and System Analyst. He is by far the greatest manager and boss I have ever seen. He understands developer's mentality very well(as he IS himself a developer). He is also a great, kind and generous guy. Our company is only a start-up company with 10 developers. Among them, only 3-4 people knows about the business logic behind the ERP, and I am one of them. If I switch my current job, it may hamper the development of this product which I really don't want. I couldn't decide what to do in this situation, so I turned to the community for advice.

• I still think Twitter is dead &hellip; but

  - by Randy Walker

  Twitter finally hit the mainstream about 8 months ago, but I’ve been saying for a couple of years now, without a real way for the company to earn money, what’s the future fate of Twitter?  On the personal side, where is the real value for the users?  For the most part, Twitter has replaced most people’s IM (instant messaging), at least in the technology circles I run in.  It still has value for users as a communication tool.  But I see it more as a fad.  My prediction is over the next 6 months we’ll start seeing a usage drop (if we haven’t already started to see it). On the business side, how does Twitter make money?  It doesn’t.  If you use the text messaging capabilities, you see a few ads.  But most smart phone and PC users, won’t ever see them.  I still think Twitter has the best chance to make money by forcing the “collectors” to pay money.  You know what I mean by “collector”, those people that collect tons of followers or friends.  If Twitter caps the number of followers and makes you pay to have more, would you?  The normal twitter user doesn’t have that many followers, and this is where my title comes in … BUT The financial value for Twitter is really seen through businesses connecting with their customers.  I’ve seen 3 effective ways this has been accomplished. 1. Giving your customers a coupon or announcing a sale My favorite is @amazonmp3, Being a huge music lover, I get notified when they put music on sale. Various restaurants like @ruthschris_ARK will let their favorite customers know about certain specials @BluefinMemphis I was traveling through Memphis once looking for a sushi restaurant when they had %50 off if we mentioned we saw them on Twitter.  It was their first attempt at trying to encourage customers in the door, and after talking with the management, it was a huge success 2. Giveaways @namecheap Several companies have started huge marketing campaigns, but my favorite is watching companies post trivia questions, and the first person to respond wins a prize. 3. Responding to Customer Complaints I once posted a complaint about American Express (a company that I have slowly come to really dislike) but they actually had someone contact me to try and resolve the issue.  I give them credit for paying attention, but still dislike them for their horrible credit practices.

• Six Unusual Blogs I Like

  - by Bill Graziano

  I subscribe to and read over 100 SQL Server blogs every day.  I link to posts that I think are interesting.  I also read a fair number of non-SQL Server blogs.  Here are a few that I think are interesting. danah boyd. She is a researcher with Microsoft and writes about privacy, social media and teenagers.  I discovered her blog while looking for strategies to keep my personal and professional life separate.  (I haven’t found a good solution to that yet.)  Her stories of how teenagers use Facebook and other social media tools are fascinating. Clayton’s Web Snacks.  Steve Clayton works at Microsoft and has a variety of blogs out there.  This one focuses on … hmmm.  His latest posts are on graffiti, infographics, paper tweets, cartoons and slow motion videos.  It’s mostly visual and you never really know what you’ll get.  It’s always interesting though and I like what he posts.  It’s good creative stuff. Seth Godin.  Seth writes about Marketing.  I read him for motivation to get off my butt and get things done.  He’s a great motivator who encourages you to think big.  And do something! Ask the Pilot.  Patrick Smith is a commercial airline pilot writing about the airline industry.  He’s a great debunker of myths (no they don’t reduce oxygen in the cabin to keep you docile).  My favorite topics include the TSA, flying myths, airport reviews and flight delays. My old favorite flight blog used to be enplaned.  No one knew who wrote it.  It focused on the economics of the airline industry.  It was fascinating stuff.  One day it was gone.  The entire blog was deleted.  Someone tracked down some partial archives and put them online. The Agent’s Journal.  Jack Bechta is an NFL agent.  He writes about the business side of the NFL, the draft and free agency.  Lately he’s been writing about the potential lockout.  He has a distinct lack of hype which I find very refreshing.  xkcd.  I call this the comic for smart people.  A little math, some IT and internet privacy thrown in all make an unusual comic. Funny and intelligent.

• Unable to add users to Microsoft Dynamics CRM 4.0 after database restore

  - by Wes Weeks

  Working with a client in our Multi-tenant CRM environment who was doing a database migration into CRM and as part of the process, a backup of their Organization_MSCRM database was taken just prior to starting the migration in case it needed to be restored and run a second time. In this case it did, so I restored the database and let the client know he should be good to go.  A few hours later I received a call that they were unable to add some new users, they would appear as available when using the add multiple user wizard, but anyone added would not be added to CRM.  It was also disucussed that these users had been added to CRM initally AFTER the database backup had been taken. I turned on tracing and tried to add the users through both the single user form and multiple user interface and was unable to do so.  The error message in the logs wasn't much help: Unexpected error adding user [email protected]: Microsoft.Crm.CrmException: INVALID_WRPC_TOKEN: Validate WRPC Token: WRPCTokenState=Invalid, TOKEN_EXPIRY=4320, IGNORE_TOKEN=False Searching on Google or bing didn't offer any assitance.  Apparently not a very common problem, or no one has been able to resolve. I did some searching in the MSCRM_CONFIG database and found that their are several user tables there and after getting my head around the structure found that there were enties here for users that were not part of the restored DB.  It seems that new users are added to both the Orgnaization_MSCRM and MSCRM_CONFIG and after the restore these were out of sync. I needed to remove the extra entries in order to address.  Restoring the MSCRM_CONFIG database was not an option as other clients could have been adding users at this point and to restore would risk breaking their instances of CRM.  Long story short, I was finally able to generate a script to remove the bad entries and when I tried to add users again, I was succesful.  In case someone else out there finds themselves in a similar situation, here is the script I used to delete the bad entries. DECLARE @UsersToDelete TABLE (   UserId uniqueidentifier )   Insert Into @UsersToDelete(UserId) Select UserId from [MSCRM_CONFIG].[dbo].[SystemUserOrganizations] Where CrmuserId Not in (select systemuserid from Organization_MSCRM.dbo.SystemUserBase) And OrganizationId = '00000000-643F-E011-0000-0050568572A1' --Id From the Organization table for this instance   Delete From [MSCRM_CONFIG].[dbo].[SystemUserAuthentication]   Where UserId in (Select UserId From @UsersToDelete)   Delete From [MSCRM_CONFIG].[dbo].[SystemUserOrganizations] Where UserId in (Select UserId From @UsersToDelete)   Delete From [MSCRM_CONFIG].[dbo].[SystemUser] Where Id in (Select UserId From @UsersToDelete)

• How valuable are you to your organization?

  - by Lance Shaw

  I don't know about you but I find it easy to get bogged down with the daily list of tasks and deliverables.  We all have lots to do and it all seems to be due tomorrow.  If you are reading this blog, than your to-do list is almost certainly filled with tasks related to the management, processing and publishing of information.  As we get mired in the daily routine of making sure that the content management needs of the organizations are met, we can easily lose sight of the value that we bring.  After all, if information and content is the lifeblood of our organizations, then surely maintaining the healthy flow of that information has real value.  But how can you measure that value and bring it forward on your résumé or your list of achievements in time for your next performance review? The AIIM organization has spent a lot of time recently researching the value of certification for "information professionals".  When it comes to enterprise content management (ECM) there are many areas of specialization including records management, content archivist, digital asset manager, content librarian and more.  Specialization can clearly drive up your value but it can also lock you into a narrow niche area of focus.  AIIM has found that what companies also need is someone that can apply their knowledge of how information is managed within the operational scope of the business in order to drive real, measurable strategic value.  When you can showcase the value of a broader, business-wide mindset to your management, you have more opportunity to make professional progress and drive real growth where it counts, your paycheck.   We here on the Oracle WebCenter team partnered with AIIM on the research they performed around the value of an information professional certification program. In a webinar this week, Doug Miles of AIIM and I will be talking about the results of that recent survey and what it is going to mean in the future to be recognized as a "Certified Information Professional" (CIP).  Oracle sponsored this research to help individuals and companies understand the value of enterprise content management and what it means across the entire organization. I hope you will join us. If any of us were stopped in the street and were asked about it, I bet most of us would think of ourselves as an "Information Professional".  Now we have a way to actually prove it!  There's only one downside that I can see...  you will have to get your business cards updated to include the "CIP" acronym after your name.  I think you will agree that is a price worth paying!

• Slides, Code, and Photos from SPTechCon San Francisco 2011

  - by Brian Jackett

  Note: Updated 2/12/11 with links to both presentation materials.     This past week I presented two sessions at SPTechCon San Francisco 2011.  The first session was “The Expanding Developer Toolbox for SharePoint 2010” which .  Thanks to all of my attendees for this session.  They had so many great questions that we ran out of time before covering all of the planned material.  Especially for them I’ve provided the slides and code samples to walk through them on their own.     The second session was “Real World Deployment of SharePoint 2007 Solutions”.  In talking with attendees before the session many were looking for 2007 content.  At the conference SharePoint 2010 was represented much more heavily than 2007, so I was glad to fill a need in the community. Slides and Code   Click here for “The Expanding Developer Toolbox for SharePoint 2010” materials   Click here for “Real World Deployment of SharePoint 2007 Solutions” materials Photos Pictures on FaceBook   Click here Pictures on Windows Live (higher res)     SPTechCon San Fran Feb 2011 VIEW SLIDE SHOW DOWNLOAD ALL Side Trips     Aside from the conference itself I also got to take a few side trips during the nights.  A special thanks to Dux Raymond Sy (Twitter) for organizing a Mongolian Hot Pot dinner on Monday (see pictures) and Michael Noel (Twitter) for organizing a Korean bbq dinner on Tuesday (again see pictures).  These were both new experiences for me and I thoroughly enjoyed the time with friends and trying something new.  Another thanks to Mark Miller (Twitter) for giving a personal tour around various sites of San Fran to myself and a few others.  It was great hearing the backstory of different neighborhoods and buildings from someone who had lived in the area for years.  Overall a great addition to the conference itself. Conclusion     This is the 3rd SPTechCon I’ve attended and the conference is getting better with each iteration.  The fine folks at BZ Media should be proud of the effort they’ve put in.  The next SPTechCon will be in Boston in June.  As of right now I won’t be attending that one but I highly recommend anyone to go if you have the chance.         -Frog Out

• Overload Avoidance

  - by mikef

  A little under a year ago, Matt Simmons wrote a rather reflective article about his terrifying brush with stress-induced ill health. SysAdmins and DBAs have always been prime victims of work-related stress, but I wonder if that predilection is perhaps getting worse, despite the best efforts of Matt and his trusty side-kick, HR. The constant pressure from share-holders and CFOs to 'streamline' the workforce is partially to blame, but the more recent culprit is technology itself. I can't deny that the rise of technologies like virtualization, PowerCLI, PowerShell, and a host of others has been a tremendous boon. As a result, individual IT professionals are now able to handle more and more tasks and manage increasingly large and complex environments. But, without a doubt, this is a two-edged sword; The reward for competence is invariably more work. Unfortunately, SysAdmins play such a pivotal role in modern business that it's easy to see how they can very quickly become swamped in conflicting demands coming from different directions. However, that doesn't justify the ridiculous hours many are asked (or volunteer) to devote to their work. Admirably though their commitment is, it isn't healthy for them, it sets a dangerous expectation, and eventually something will snap. There are times when everyone needs to step up to the plate outside of 'normal' work hours, but that time isn't all the time. Naturally, with all that lovely technology, you can automate more and more of those tricky tasks to keep on top of the workload, but you are still only human. Clever though you may be, there is a very real limit to how far technology can take you. I'm not suggesting that you avoid these technologies, or deliberately aim for mediocrity; I'm just saying that you need to be more than just technically skilled (and Wesley Nonapeptide riffs on and around this topic in his excellent 'Telepathic Robot Drones' blog post). You need to be able to manage expectations, not just Exchange. Specifically, that means your own expectations of what you are capable of, because those come before everyone else's. After all, how can you keep your work-life balance under control, if you're the one setting the bar way too high? Talking to your manager, or discussing issues with your users, is only going to be productive if you have some facts to work with. "Know Thyself" is the first law of managing work overload, and this is obviously a skill which people develop over time; the fact that veteran Sysadmins exist at all is testament to this. I'd just love to know how you get to that point. Personally, I'm using RescueTime to keep myself honest, but I'm open to recommendations for better methods. Do you track your own time, do you have an intuitive sense of what is possible, or do you just rely on someone else to handle that all for you? Cheers, Michael

• Such thing as a free lunch

  - by red@work

  There is a lot of hard work goes on in Red Gate, no doubt. And then there are things we're asked to get involved with, that aren't hard and don't feel much like work. What? Give up our free lunch at Red Gate for. a free lunch in a pub? Within an hour, myself and a colleague are at the Railway Vue pub in nearby Impington. This is all part of Red Gate's aim to hire more Software Engineers and Test Engineers, to help Red Gate grow into one of the greatest software companies in the world (it's already the best small software development company in the UK). Phase one then - buy lunch for Cambridge. Seriously, not just the targeted engineers, but for anyone who could print the voucher and make it to the nearest of the venues, two of which happen to be pubs. We're here to watch people happily eat a free pub lunch at Red Gate's expense. We also get involved and I swear I didn't order a beer with the food but the landlord says I clearly did and I'm not one to argue. Red Gate are offering a free iPad to anyone that comes to interview for a Software Engineer or Test Engineer role. We speak to a few engineers who are genuinely interested. We speak to a couple of DBA's too, and encourage them to make speculative applications - no free iPad on offer for them, but that's not really the point. The point is, everyone should apply to work here! It's that good. We overhear someone ask if 'these vouchers really work?' They do. There's no catch. The free IPad? Again, no catch. If that's what it takes to get talented engineers through our doors for an interview, then that's all good. Once they see where we work and how we work, we think they'll want to come and work with us. The following day, Red Gate decides to repeat the offer, and that means more hard work, this time at The Castle pub. Another landlord that mishears 'mineral water' and serves me a beer. There are many more people clutching the printed vouchers and they all seem very happy to be getting a free lunch from Red Gate. "Come and work for us" we suggest, "lunch is always free!" So if you're a talented engineer, like free lunches and want a free iPad, you know what to do.

• Android, how important is deltaTime?

  - by iQue

  Im making a game that is getting pretty big and sometimes my thread has to skip a frame, so far I'm not using deltaTime for setting the speed of my different objects in the game because it's still not a big enough game for it to matter imo. But its getting bigger then I planned, so my question is, how important is delta Time? If I should use delta time there is a problem, since speedX and speedY are integers(they have to be for eclipse to let you make a rectangle of them), I cant add delta time very functionally as far as I understand, but might be wrong? Ive tried adding deltaTime to the code below, and sometimes my enemies just not move after spawn, they just stand there and run in the same place Will add an some code for how I set / use speed: public void update(int dx, int dy) { double theta = 180.0 / Math.PI * Math.atan2(-(y - controls.pointerPosition.y), controls.pointerPosition.x - x); x +=dx * Math.cos(Math.toRadians(theta)); y +=dy * Math.sin(Math.toRadians(theta)); currentFrame = ++currentFrame % BMP_COLUMNS; } public void draw(Canvas canvas) { int srcX = currentFrame * width; int srcY = 1 * height; Rect src = new Rect(srcX, srcY, srcX + width, srcY + height); Rect dst = new Rect(x, y, x + width, y + height); canvas.drawBitmap(bitmap, src, dst, null); } So if someone with some experience with this has any thoughts, please share. Thank you! Changed code: public void update(int dx, int dy, float delta) { double theta = 180.0 / Math.PI * Math.atan2(-(y - controls.pointerPosition.y), controls.pointerPosition.x - x); double speedX = delta * dx * Math.cos(Math.toRadians(theta)); double speedY = delta * dy * Math.sin(Math.toRadians(theta)); x += speedX; y += speedY; currentFrame = ++currentFrame % BMP_COLUMNS; } public void draw(Canvas canvas) { int srcX = currentFrame * width; int srcY = 1 * height; Rect src = new Rect(srcX, srcY, srcX + width, srcY + height); Rect dst = new Rect(x, y, x + width, y + height); canvas.drawBitmap(bitmap, src, dst, null); } with this code my enemies move like before, except they wont move to the right (wont increment x), all other directions work.

• Which web framework to use under Backbonejs?

  - by egidra

  For a previous project, I was using Backbonejs alongside Django, but I found out that I didn't use many features from Django. So, I am looking for a lighter framework to use underneath a Backbonejs web app. I never used Django built in templates. When I did, it was to set up the initial index page, but that's all. I did use the user management system that Django provided. I used the models.py, but never views.py. I used urls.py to set up which template the user would hit upon visiting the site. I noticed that the two features that I used most from Django was South and Tastypie, and they aren't even included with Django. Particularly, django-tastypie made it easy for me to link up my frontend models to my backend models. It made it easy to JSONify my front end models and send them to Tastypie. Although, I found myself overriding a lot of tastypie's methods for GET, PUT, POST requests, so it became useless. South made it easy to migrate new changes to the database. Although, I had so much trouble with South. Is there a framework with an easier way of handling database modifications than using South? When using South with multiple people, we had the worse time keeping our databases synced. When someone added a new table and pushed their migration to git, the other two people would spend days trying to use South's automatic migration, but it never worked. I liked how Rails had a manual way of migrating databases. Even though I used Tastypie and South a lot, I found myself not actually liking them because I ended up overriding most Tastypie methods for each Resource, and I also had the worst trouble migrating new tables and columns with South. So, I would like a framework that makes that process easier. Part of my problem was that they are too "magical". Which framework should I use? Nodejs or a lighter Python framework? Which works best with my above criteria?

• Virtual Box - How to open a .VDI Virtual Machine

  - by [email protected]

  TUESDAY, APRIL 27, 2010 How to open a .VDI Virtual MachineSometimes someone share with us one Virtual machine with extension .VDI, after that we can wonder how and what with?Well the answer is... It is a VirtualBox - Virtual Machine. If you have not downloaded it you can do this easily just follow this post.http://listeningoracle.blogspot.com/2010/04/que-es-virtualbox.htmlorhttp://oracleoforacle.wordpress.com/2010/04/14/ques-es-virtualbox/Ok, Now with VirtualBox Installed open it and proceed with the following:1. Open the Virtual File Manager.2. Click on Actions ? Add and select the .VDI fileClick "Ok"3. Now we can register the new Virtual Machine - Click New, and Click Next4. Write down a Name for the virtual Machine a proceed to select a Operating System and Version. (In this case it is a Linux (Oracle Enterprise Linux or RedHat)Click Next5. Select the memory amount base for the Virtual Machine(Minimal 1280 for our case) - Click Next6. Select the Disk 11GR2_OEL5_32GB.vdi it was added in the virtual media manager in the step 2.Dont forget let selected Boot hard Disk (Primary Master) . Given it is the only disk assigned to the virtual machine.Click Next7. Click Finish8. This step is important. Once you have click on the settings Button. 9. On General option click the advanced settings. Here you must change the default directory to save your Snapshots; my recommendation set it to the same directory where the .Vdi file is. Otherwise you can have the same Virtual Machine and its snapshots in different paths.10. Now Click on System, and proceed to assign the correct memory (If you did not before)Note: Enable "Enable IO APIC" if you are planning to assign more than one CPU to the Virtual Machine.Define the processors for the Virtual machine. If you processor is dual core choose 211. Select the video memory amount you want to assign to the Virtual Machine12. Associated more storage disk to the Virtual machine, if you have more VDI files.(Not our case)The disk must be selected as IDE Primary Master.13. Well you can verify the other options, but with these changes you will be able to start the VM.Note: Sometime the VM owner may share some instructions, if so follow his instructions.14. Finally Start the Virtual Machine (Click > Start)

I'm not creating a derivative work ( I plan to provide it as it is ). I don't have a NOTICE file, just my my own LICENSE.txt file. Question: Where should I put something along the lines: "This project uses Xyz library distributed under Apache2.0 ..."? What's recommented? Should I provide the apache license file too? Or would be enough if I just say "Find the license online here...http://www.apache.org/licenses/LICENSE-2.0.html" I hope someone who has done this in the past may shed some light on the matter.

  Above and Beyond with the A-Team Maybe it's the coffee… If you follow this blog you've probably noticed that I regularly feature posts from members of the Oracle Fusion Middleware Architecture team, otherwise known as the A-Team. One of those bloggers, someone identified only as "fip" who writes on the A-Team SOA blog, went above and beyond on Dec 4, publishing a total of four substantial technical posts in a single day, each one worth a look: Retrieve Performance Data from SOA Infrastructure Database Configure Oracle SOA JMSAdatper to Work with WLS JMS Topics How to Achieve OC4J RMI Load Balancing Using BPEL Performance Statistics to Diagnose Performance Bottlenecks Web Service Example - Part 3: Asynchronous | The Oracle ADF Mobile Blog Part 3 in this series from the Oracle ADF Mobile blog looks at "firing the web service asynchronously and then filling in the UI when it completes." Denis says, "This can be useful when you have data on the device in a local store and want to show that to the user while the application uses lazy loading from a web service to load more data." ADF Mobile - Implementing Reusable Mobile Architecture | Andrejus Baranovskis "Reusability was always a strong part of ADF," says Oracle ACE Director Andrejus Baranovskis. "The same high reusability level is supported now in ADF Mobile." The objective of this post is "to prove technically that [the] reusable architecture concept works for ADF Mobile." Basic is Best | Eric Stephens "The world we live in and enterprises we strive to transform with enterprise architecture are complicated organisms, much like the human body," says Oracle Enterprise Architect Eric Stephens. "But sometimes a simple solution is the best approach...Whatever level of abstraction you are working at, less is more." Selling Federal Enterprise Architecture | Ted McLaughlan "EA must be 'sold' directly to the communities that matter from a coordinated, proactive messaging perspective that takes BOTH the Program-level value drivers AND the broader Agency mission and IT maturity context into consideration, " explains Ted McLaughlan. And that's true for any organization. Avoiding the "I'm Spartacus" Scenario in SOA | Ben Wilcock "This ‘SOA Spartacus’ scenario usually occurs quite soon after SOA is articulated as the primary strategic direction of the programme," says Ben Wilcock, "but before the organisation’s SOA capability is mature enough to understand what is meant by SOA, and how it should be designed and delivered." In such cases, perhaps the "A" in SOA is missing, no? Thought for the Day "It makes me feel guilty that anybody should have such a good time doing what they are supposed to do." — Charles Eames (1907–1978) Source: SoftwareQuotes.com
