• Any tips on getting hired as a software project manager straight out of college?

  - by MHarrison

  I graduated with a BS in compsci last September, and I've been trying (unsuccessfully) to find a job as a project manager ever since. I fell in love with software engineering (the formal practice behind it all, not just coding) in school, and I've dedicated the last 3-4 years of my life to learning everything I can about project management and gaining experience. I've managed several projects (with teams around 12 people) while in school, and I worked with my university's software engineering research lab. My résumé is also decent - I worked as a programmer before I went to school (I'm 27 now), and I did Google Summer of Code for 3 summers. I also have general "people management" experience via working as the photo editor for my university's newspaper for 2 years. My first problem with the job hunt is not getting enough interviews. I use careers.stackoverflow.com, which is awesome because I usually get contacted by non-HR people who know what they're talking about, but there's just not enough companies using it for me to get interviews on a regular basis. I've also tried sites like monster.com, and in a fit of desperation, I sent out no less than 60 applications to project management positions. I've gotten 3 automated rejection letters and that's it. At least careers.stackoverflow gets me a phone interview with 8/10 places I apply to. But the main (and extremely frustrating) problem is the matter of experience. I've successfully managed projects from start to finish (in my software engineering classes we had real customers come in with a real software need and we built it for them), but I've never had to deal with budgets and money (I know this is why HR people immediately turn me away). Most of these positions require 5+ years PM experience, and I've seen absurd things like 12+ years required. Interviews are also maddening. I've had so many places who absolutely loved me and I made it to the final round of interviews, and I left thinking things went extremely well and they'd consider me. However, when I check in with them a week later, they tell me "We really liked you and your qualifications are excellent, but we're hoping to find someone with more experience." The bad interviews I can understand - like the PM position that would have had me managing developers both locally and overseas - I had 3 interviews with them and the ENTIRE interview process was them asking me CS brainteasers and having me waste time on things like writing quicksort on paper or writing binary search trees. Even when I tried steering the discussion towards more relevant PM stuff, they gave me some vague generic replies and went back to the "We want to be Google/MS" crap. But when I have a GOOD interview, they say my "qualifications are excellent" but they want "more experience"...that makes me want to tear my hair out. What else can I DO? While I'm aiming for technically-involved PM positions (not just crunching budget numbers), I really don't want a straight development job because I like creating software from the very high-level vs. spending a lot of time debugging memory leaks. In fact, I can't even GET development positions that I'm qualified for because I make the mistake of telling them that my future career goals are as PM (which usually results in them saying something like "Well we already have PMs and this position isn't really set up to get you there." - which I take to mean "No, that's my job, stay away.") My apologies on the long rant, but I'm seriously hellbent on getting hired as a PM since it's both my career goal and the passion that keeps me awake at night. Any suggestions on what the heck else I can do? I'm currently writing a blog where I talk about my philosophies about software engineering, and I'm writing up specs for an iOS app which I will design, code, and show employers, but this takes an awful lot of time that I don't have.

• SQL Saturday 27 (Portland, Oregon)

  - by BuckWoody

  I’m sitting in the Seattle airport, waiting for my flight to Silicon Valley California for the SQL Server 2008 R2 Launch Event. By some quirk of nature, they are asking me to Emcee the event – but that’s another post entirely.   I’m reflecting on the SQL Saturday 27 event that was just held in Portland, Oregon this last Saturday. These are not Microsoft-sponsored events – it’s truly the community at work. Think of a big user-group meeting – I mean REALLY big – held in a central location, like at a college (as ours was) or some larger, inexpensive venue like that. Everyone there is volunteering – it’s my own money and time to drive several hours to a hotel for the night, feed myself and present. It’s their own time and money for the folks that organize the event – unless a vendor or two steps in to help. It’s their own time and money for the attendees to drive a long way, spend the night and their Saturday to listen to the speakers. Why do all this?   Because everybody benefits. Every speaker learns something new, meets new people, and reaches a new audience. Every volunteer does the same. And the attendees? Well, it’s pretty obvious what they get. A 7Am to 10PM extravaganza of knowledge from every corner of the product. In fact, this year the Portland group hooked up with the CodeCamp folks and held a combined event. We had over 850 people, and I had everyone from data professionals to developers in my sessions.   So I’ll take this opportunity to do two things: to say “thank you” to all of the folks who attended, from those who spoke to those who worked and those who came to listen, and to challenge you to attend the next SQL Saturday anywhere near you. You can find the list here: http://www.sqlsaturday.com/. Don’t see anything in your area? Start one! The PASS folks have a package that will show you how. Sure, it’s a big job, but the key is to get as many people helping you as possible. Even if you have only a few dozen folks show up the first time, no worries. The first events I presented at had about 20 in the room. But not this week.   See you at the Launch Event if you’re near the San Francisco area tomorrow, and see you at the Redmond SQL Saturday and TechEd if not.   Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• Extrapolation breaks collision detection

  - by user22241

  Before applying extrapolation to my sprite's movement, my collision worked perfectly. However, after applying extrapolation to my sprite's movement (to smooth things out), the collision no longer works. This is how things worked before extrapolation: However, after I implement my extrapolation, the collision routine breaks. I am assuming this is because it is acting upon the new coordinate that has been produced by the extrapolation routine (which is situated in my render call ). After I apply my extrapolation How to correct this behaviour? I've tried puting an extra collision check just after extrapolation - this does seem to clear up a lot of the problems but I've ruled this out because putting logic into my rendering is out of the question. I've also tried making a copy of the spritesX position, extrapolating that and drawing using that rather than the original, thus leaving the original intact for the logic to pick up on - this seems a better option, but it still produces some weird effects when colliding with walls. I'm pretty sure this also isn't the correct way to deal with this. I've found a couple of similar questions on here but the answers haven't helped me. This is my extrapolation code: public void onDrawFrame(GL10 gl) { //Set/Re-set loop back to 0 to start counting again loops=0; while(System.currentTimeMillis() > nextGameTick && loops < maxFrameskip){ SceneManager.getInstance().getCurrentScene().updateLogic(); nextGameTick+=skipTicks; timeCorrection += (1000d/ticksPerSecond) % 1; nextGameTick+=timeCorrection; timeCorrection %=1; loops++; tics++; } extrapolation = (float)(System.currentTimeMillis() + skipTicks - nextGameTick) / (float)skipTicks; render(extrapolation); } Applying extrapolation render(float extrapolation){ //This example shows extrapolation for X axis only. Y position (spriteScreenY is assumed to be valid) extrapolatedPosX = spriteGridX+(SpriteXVelocity*dt)*extrapolation; spriteScreenPosX = extrapolationPosX * screenWidth; drawSprite(spriteScreenX, spriteScreenY); } Edit As I mentioned above, I have tried making a copy of the sprite's coordinates specifically to draw with.... this has it's own problems. Firstly, regardless of the copying, when the sprite is moving, it's super-smooth, when it stops, it's wobbling slightly left/right - as it's still extrapolating it's position based on the time. Is this normal behavior and can we 'turn it off' when the sprite stops? I've tried having flags for left / right and only extrapolating if either of these is enabled. I've also tried copying the last and current positions to see if there is any difference. However, as far as collision goes, these don't help. If the user is pressing say, the right button and the sprite is moving right, when it hits a wall, if the user continues to hold the right button down, the sprite will keep animating to the right, while being stopped by the wall (therefore not actually moving), however because the right flag is still set and also because the collision routine is constantly moving the sprite out of the wall, it still appear to the code (not the player) that the sprite is still moving, and therefore extrapolation continues. So what the player would see, is the sprite 'static' (yes, it's animating, but it's not actually moving across the screen), and every now and then it shakes violently as the extrapolation attempts to do it's thing....... Hope this help

• Designing An ACL Based Permission System

  - by ryanzec

  I am trying to create a permissions system where everything is going to be stored in MySQL (or some database) and pulled using PHP for a project management system I am building.  I am right now trying to do it is an ACL kind of way.  There are a number key features I want to be able to support: 1.  Being able to assign permissions without being tied to a specific object. The reason for this is that I want to be able to selectively show/hide elements of the UI based on permissions at a point where I am not directly looking at a domain object instance.  For instance, a button to create a new project should only should only be shown to users that have the pm.project.create permission but obviously you can assign a create permission to an domain object instance (as it is already created). 2.  Not have to assign permissions for every single object. Obviously creating permissions entries for every single object (projects, tickets, comments, etc…) would become a nightmare to maintain so I want to have some level of permission inheritance. *3.  Be able to filter queries based on permissions. This would be a really nice to have but I am not sure if it is possible.  What I mean by this is say I have a page that list all projects.  I want the query that pulls all projects to incorporate the ACL so that it would not show projects that the current user does not have pm.project.read access to.  This would have to be incorporated into the main query as if it is a process that is done after that main query (which I know I could do) certain features like pagination become much more difficult. Right now this is my basic design for the tables: AclEntities id - the primary key key - the unique identifier for the domain object (usually the primary key of that object) parentId - the parent of the domain object (like the project object if this was a ticket object) aclDomainObjectId - metadata about the domain object AclDomainObjects id - primary key title - simple string to unique identify the domain object(ie. project, ticket, comment, etc…) fullyQualifiedClassName - the fully qualified class name for use in code (I am using namespaces) There would also be tables mapping AclEntities to Users and UserGroups. I also have this interface that all acl entity based object have to implement: IAclEntity getAclKey() - to the the unique key for this specific instance of the acl domain object (generally return the primary key or a concatenated string of a composite primary key) getAclTitle() - to get the unique title for the domain object (generally just returning a static string) getAclDisplayString() - get the string that represents this entity (generally one or more field on the object) getAclParentEntity() - get the parent acl entity object (or null if no parent) getAclEntity() - get the acl enitty object for this instance of the domain object (or null if one has not been created yet) hasPermission($permissionString, $user = null) - whether or not the user has the permission for this instance of the domain object static getFromAclEntityId($aclEntityId) - get a specific instance of the domain object from an acl entity id. Do any of these features I am looking for seems hard to support or are just way off base? Am I missing or not taking in account anything in my implementation? Is performance something I should keep in mind?

• Mobile Deals: the Consumer Wants You in Their Pocket

  - by Mike Stiles

  Mobile deals offer something we talk about a lot in social marketing, relevant content. If a consumer is already predisposed to liking your product and gets a timely deal for it that’s easy and convenient to use, not only do you score on the marketing side, it clearly generates some of that precious ROI that’s being demanded of social. First, a quick gut-check on the public’s adoption of mobile. Nielsen figures have 55.5% of US mobile owners using smartphones. If young people are indeed the future, you can count on the move to mobile exploding exponentially. Teens are the fastest growing segment of smartphone users, and 58% of them have one. But the largest demographic of smartphone users is 25-34 at 74%. That tells you a focus on mobile will yield great results now, and even better results straight ahead. So we can tell both from statistics and from all the faces around you that are buried in their smartphones this is where consumers are. But are they looking at you? Do you have a valid reason why they should? Everybody likes a good deal. BIA/Kelsey says US consumers will spend $3.6 billion this year for daily deals (the Groupons and LivingSocials of the world), up 87% from 2011. The report goes on to say over 26% of small businesses are either "very likely" or "extremely likely" to offer up a deal in the next 6 months. Retail Gazette reports 58% of consumers shop with coupons, a 40% increase in 4 years. When you consider that a deal can be the impetus for a real-world transaction, a first-time visit to a store, an online purchase, entry into a loyalty program, a social referral, a new fan or follower, etc., that 26% figure shows us there’s a lot of opportunity being left on the table by brands. The existing and emerging technologies behind mobile devices make the benefits of offering deals listed above possible. Take how mobile payment systems are being tied into deal delivery and loyalty programs. If it’s really easy to use a coupon or deal, it’ll get used. If it’s complicated, it’ll be passed over as “not worth it.” When you can pay with your mobile via technologies that connects store and user, you get the deal, you get the loyalty credit, you pay, and your receipt is uploaded, all in one easy swipe. Nothing to keep track of, nothing to lose or forget about. And the store “knows” you, so future offers will be based on your tastes. Consider the endgame. A customer who’s a fan of your belt buckle store’s Facebook Page is in one of your physical retail locations. They pull up your app, because they’ve gotten used to a loyalty deal being offered when they go to your store. Voila. A 10% discount active for the next 30 minutes. Maybe the app also surfaces social references to your brand made by friends so they can check out a buckle someone’s raving about. If they aren’t a fan of your Page or don’t have your app, perhaps they’ve opted into location-based deal services so you can still get them that 10% deal while they’re in the store. Or maybe they’ve walked in with a pre-purchased Groupon or Living Social voucher. They pay with one swipe, and you’ve learned about their buying preferences, credited their loyalty account and can encourage them to share a pic of their new buckle on social. Happy customer. Happy belt buckle company. All because the brand was willing to use the tech that’s available to meet consumers where they are, incentivize them, and show them how much they’re valued through rewards.

• Help Me Help You Fix That

  - by BuckWoody

  If you've been redirected here because you posted on a forum, or asked a question in an e-mail, the person wanted you to know how to get help quickly from a group of folks who are willing to do so - but whose time is valuable. You need to put a little effort into the question first to get others to assist. This is how to do that. It will only take you a moment to read... 1. State the problem succinctly in the title When an e-mail thread starts, or a forum post is the "head" of the conversation, you'll attract more helpers by using a descriptive headline than a vague one. This: "Driver for Epson Line Printer Not Installing on Operating System XYZ" Not this: "Can't print - PLEASE HELP" 2. Explain the Error Completely Make sure you include all pertinent information in the request. More information is better, there's almost no way to add too much data to the discussion. What you were doing, what happened, what you saw, the error message, visuals, screen shots, whatever you can include. This: "I'm getting error '5203 - Driver not compatible with Operating System since about 25 years ago' in a message box on the screen when I tried to run the SETUP.COM file from my older computer. It was a 1995 Compaq Proliant and worked correctly there.." Not this: "I get an error message in a box. It won't install." 3. Explain what you have done to research the problem If the first thing you do is ask a question without doing any research, you're lazy, and no one wants to help you. Using one of the many fine search engines you can most always find the answer to your problem. Sometimes you can't. Do yourself a favor - open a notepad app, and paste the URL's as you look them up. If you get your answer, don't save the note. If you don't get an answer, send the list along with the problem. It will show that you've tried, and also keep people from sending you links that you've already checked. This: "I read the fine manual, and it doesn't mention Operating System XYZ for some reason. Also, I checked the following links, but the instructions there didn't fix the problem: " Not this: <NULL> 4. Say "Please" and "Thank You" Remember, you're asking for help. No one owes you their valuable time. Ask politely, don't pester, endure the people who are rude to you, and when your question is answered, respond back to the thread or e-mail with a thank you to close it out. It helps others that have your same problem know that this is the correct answer. This: "I could really use some help here - if you have any pointers or things to try, I'd appreciate it." Not this: "I really need this done right now - why are there no responses?" This: "Thanks for those responses - that last one did the trick. Turns out I needed a new printer anyway, didn't realize they were so inexpensive now." Not this: <NULL> There are a lot of motivated people that will help you. Help them do that.

When we first started talking about "paper-free" most of the reasons raised to pursue this direction were "green" reasons.  I'm glad to see that the thinking has moved on to questions about how getting rid of paper and digitizing processes helps improve customer engagement.  And the bottom line.  And process responsiveness.  Not that the "green" reasons have gone away, but it's nice to see a maturation in the BUSINESS reasons to get rid of paper. Our World Paper Free Handbook (do not, do not, do not print it!) looks at how less paper in the workplace delivers significant benefits. Key findings show eliminating paper from processes can improve the responsiveness of customer service by 300 percent. Removing paper from business processes and moving content to PCs and tablets has the added advantage of helping companies adopt mobile-enable processes and eliminate elapsed time, lost forms, poor data and re-keying. To effectively mobile-enable processes and reduce reliance on paper, data should be captured as close to the point of origination as possible, which makes information easily available to whomever needs it, wherever they are, in the shortest time possible. This handbook summarizes the value of automating manual, paper-based processes. It then goes a step beyond to provide actionable steps that will set you on the path to productivity, profitability, and, yes, less paper.  Get your copy today and send the link around to your peers and colleagues.  Here's the link; please share it! http://www.aiim.org/Research-and-Publications/Research/AIIM-White-Papers/WPFD-Revolution-Handbook And don't miss out on the real world discussions about increasing engagement with WebCenter in new webinars being offered over the next couple of weeks:  October 30, 2012:  ResCare Solves Content Lifecycle Challenges with Oracle WebCenter November 1, 2012: WebCenter Content for Applications: Streamline Processes with Oracle WebCenter Content Management for Human Resources Applications Available On-Demand:  Using Oracle WebCenter to Content-Enable Your Business Applications

• What Color is your Jetpack ?

  - by JoshReuben

  I’m a programmer, Im approaching 40, and I’m fairly decent at my job – I’ll keep doing what I’m doing for as long as they let me!   So what are your career options if you know how to code? A Programmer could be ..   An Algorithm developer Pros Interesting High barriers of entry, potential for startup competitive factor Cons Do you have the skill, qualifications? What are working conditions n this mystery niche ? micro-focus An Academic Pros Low pressure Job security – or is this an illusion ? Cons Low Pay Need a PhD A Software Architect Pros: strategic, rather than tactical Setting technology platform and high level vision You say how it should work, others have to figure out why its not working the way its supposed to ! broad view – you are paid to learn (how do you con people into paying for you to learn ??) Cons: Glorified developer – more often than not! competitive – everyone wants to do it ! loose touch with underlying tech in tough times, first guy to get the axe ! A Software Engineer Pros: interesting, always more to learn fun I can do it Fallback Cons: Nothing new under the sun – been there, done that Dealing with poor requirements, deadlines, other peoples code, overtime C#, XAML, Web - Low barriers of entry –> à race to the bottom A Team leader Pros: Setting code standards and proposing technology choices Cons: Glorified developer – more often than not! Inspecting other peoples code and debugging the problems they cannot fix Dealing with mugbies and prima donas Responsible for QA of others A Project Manager Pros No need for debugging other peoples code Cons Low barrier of entry High pressure Responsible for QA of others Loosing touch with technology A lot of bullshit meetings Have to be an asshole A Product Manager Pros No need for debugging other peoples code Learning new skillset of sales and marketing Cons Travel (I'm a family man) May need to know the bs details of an uninteresting product things I want to work with: AI, algorithms, Numerical Computing, Mathematica, C++ AMP – unfortunately, the work here is few & far between. VS & TFS Extensibility, DSLs (Workflow , Lightswitch), Code Generation – one day, code will write code ! Unity3D, WebGL – fun, fun, fun ! Modern Web – Knockout, SignalR, MVC, Node.Js ??? (tentative – I'll wait until things stabilize as this area is undergoing a pre-Cambrian explosion) Things I don’t want to work with: (but will if I'm asked to !) C# – same old, same old – not learning anything new here Old code – blech ! Environment with code & fix mentality , ad hoc requirements, excessive overtime Pc support, System administration – even after 20 years, people still ask you to do this sometimes ! debugging – my skills are just not there yet Oracle Old tech: VB 6, XSLT, WinForms, Net 3.51 or less Old style Web dev Information Systems: ASP.NET webforms, Reporting services / crystal reports, SQL Server CRUD with manual data layer, XAML MVVM – variations of the same concept, ad nauseaum. Low barriers of entry –> race to the bottom.  Metro – an elegant API coupled to a horrendous UX – I'll wait for market penetration viability before investing further in this.   Conclusion So if you are in a slump, take heart: Programming is a great career choice compared to every other job !

• Know your Data Lineage

  - by Simon Elliston Ball

  An academic paper without the footnotes isn’t an academic paper. Journalists wouldn’t base a news article on facts that they can’t verify. So why would anyone publish reports without being able to say where the data has come from and be confident of its quality, in other words, without knowing its lineage. (sometimes referred to as ‘provenance’ or ‘pedigree’) The number and variety of data sources, both traditional and new, increases inexorably. Data comes clean or dirty, processed or raw, unimpeachable or entirely fabricated. On its journey to our report, from its source, the data can travel through a network of interconnected pipes, passing through numerous distinct systems, each managed by different people. At each point along the pipeline, it can be changed, filtered, aggregated and combined. When the data finally emerges, how can we be sure that it is right? How can we be certain that no part of the data collection was based on incorrect assumptions, that key data points haven’t been left out, or that the sources are good? Even when we’re using data science to give us an approximate or probable answer, we cannot have any confidence in the results without confidence in the data from which it came. You need to know what has been done to your data, where it came from, and who is responsible for each stage of the analysis. This information represents your data lineage; it is your stack-trace. If you’re an analyst, suspicious of a number, it tells you why the number is there and how it got there. If you’re a developer, working on a pipeline, it provides the context you need to track down the bug. If you’re a manager, or an auditor, it lets you know the right things are being done. Lineage tracking is part of good data governance. Most audit and lineage systems require you to buy into their whole structure. If you are using Hadoop for your data storage and processing, then tools like Falcon allow you to track lineage, as long as you are using Falcon to write and run the pipeline. It can mean learning a new way of running your jobs (or using some sort of proxy), and even a distinct way of writing your queries. Other Hadoop tools provide a lot of operational and audit information, spread throughout the many logs produced by Hive, Sqoop, MapReduce and all the various moving parts that make up the eco-system. To get a full picture of what’s going on in your Hadoop system you need to capture both Falcon lineage and the data-exhaust of other tools that Falcon can’t orchestrate. However, the problem is bigger even that that. Often, Hadoop is just one piece in a larger processing workflow. The next step of the challenge is how you bind together the lineage metadata describing what happened before and after Hadoop, where ‘after’ could be  a data analysis environment like R, an application, or even directly into an end-user tool such as Tableau or Excel. One possibility is to push as much as you can of your key analytics into Hadoop, but would you give up the power, and familiarity of your existing tools in return for a reliable way of tracking lineage? Lineage and auditing should work consistently, automatically and quietly, allowing users to access their data with any tool they require to use. The real solution, therefore, is to create a consistent method by which to bring lineage data from these data various disparate sources into the data analysis platform that you use, rather than being forced to use the tool that manages the pipeline for the lineage and a different tool for the data analysis. The key is to keep your logs, keep your audit data, from every source, bring them together and use the data analysis tools to trace the paths from raw data to the answer that data analysis provides.

• What's wrong with my wireless?

  - by dazzle

  I am having issues with my wireless connection. My connection is constantly disconnecting, then attempting to reconnect, reconnecting momentarily, then disconnecting etc. on times scales that range from seconds to minutes. In the meantime, needless to say I'm having significant packet loss. I'm running Ubuntu 14.04 64bit, updated and upgraded to today.

• News From EAP Testing

  - by Fatherjack

  There is a phrase that goes something like “Watch the pennies and the pounds/dollars will take care of themselves”, meaning that if you pay attention to the small things then the larger things are going to fare well too. I am lucky enough to be a Friend of Red Gate and once in a while I get told about new features in their tools and have a test copy of the software to trial. I got one of those emails a week or so ago and I have been exploring the SQL Prompt 6 EAP since then. One really useful feature of long standing in SQL Prompt is the idea of a code snippet that is automatically pasted into the SSMS editor when you type a few key letters. For example I can type “ssf” and then press the tab key and the text is expanded to SELECT * FROM. There are lots of these combinations and it is possible to create your own really easily. To create your own you use the Snippet Manager interface to define the shortcut letters and the code that you want to have put in their place. Let’s look at an example. Say I am writing a blog about something and want to have the demo code create a temporary table. It might looks like this; The first time you run the code everything is fine, a lovely set of dates fill the results grid but run it a second time and this happens.   Yep, we didn’t destroy the temporary table so the CREATE statement fails when it finds the table already exists. No matter, I have a snippet created that takes care of this.   Nothing too technical here but you will see that in the Code section there is $CURSOR$, this isn’t a TSQL keyword but a marker for SQL Prompt to place the cursor in that position when the Code is pasted into the SSMS Editor. I just place my cursor above the CREATE statement and type “ifobj” – the shortcut for my code to DROP the temporary table – which has been defined in the Snippet Manager as below. This means I am right-away ready to type the name of the offending table. Pretty neat and it’s been very useful in saving me lots of time over many years.   The news for SQL Prompt 6 is that Red Gate have added a new Snippet Command of $PASTE$. Let’s alter our snippet to the following and try it out   Once again, we will type type “ifobj” in the SSMS Editor but first of all, highlight the name of the table #TestTable and copy it to your clipboard. Now type “ifobj” and press Tab… Wherever the string $PASTE$ is placed in the snippet, the contents of your clipboard are merged into the pasted TSQL. This means I don’t need to type the table name into the code snippet, it’s already there and I am seeing a fully functioning piece of TSQL ready to run. This means it is it even easier to write TSQL quickly and consistently. Attention to detail like this from Red Gate means that their developer tools stay on track to keep winning awards year after year and help take the hard work out of writing neat, accurate TSQL. If you want to try out SQL Prompt all the details are at http://www.red-gate.com/products/sql-development/sql-prompt/.

• Would this be a good web application architecture?

  - by Gustav Bertram

  My problem Our MVC based framework does not allow us to cache only part of our output. Ideally we want to cahce static and semi-static bits, and run dynamic bits. In addition, we need to consider data caching that reacts to database changes. My idea The concept I came up with was to represent a page as a tree of XML fragment objects. (I say XML, but I mean XHTML). Some of the fragments are dynamic, and can pull their data directly from models or other sources, but most of the fragments are static scaffolding. If a subtree of fragments is completely static, then I imagine that they could unfold into pure XML that would then be cached as the text representation of their parent element. This process would ideally continue until we are left with a root element that contains all of the static XML, and has a couple of dynamic XML fragments that are resolved and attached to the relevant nodes of the XML tree just before the page is displayed. In addition to separating content into dynamic and static fragments, some fragments could be dynamic and cached. A simple expiry time which propagates up through the XML fragment tree would indicate that a specific fragment should periodically be refreshed. A newspaper section or front page does not need to be updated each second. Minutes or sometimes even longer is sufficient. Other fragments would be dynamic and uncached. Typically too many articles are viewed for them to be cached - the cache would overflow. Some individual articles may be cached if they are extremely popular. Functional notes The folding mechanism could be to be smart enough to judge when it would be more profitable to fold a dynamic cached fragment and propagate the expiry date to the parent fragment, or to keep it separate and simple attach to the XML tree when resolving the page. If some dynamic cached fragments are associated to database objects through mechanisms like a globally unique content id, then changes to the database could trigger changes to the output cache. If fragments store the identifiers of parent fragments, then they could trigger a refolding process that would then include the updated data. A set of pure XML with an ordered array of fragment objects (that each store the identifying information of the node to which they should be attached), can be resolved in a fairly simple way by walking the XML tree, and merging the data from the fragments. Because it is not necessary to parse and construct the entire tree in memory before attaching nodes, processing should be fairly fast. The identifiers of each fragment would be a combination of relevant identity data and the type of fragment object. Cached parent fragments would contain references to these identifiers, in order to then either pull them from the fragment cache, or to run their code. The controller's responsibility is reduced to making changes to the database, and telling the root XML fragment object to render itself. The Question My question has two parts: Is this a good design? Are there any obvious flaws I'm missing? Has somebody else thought of this before? References? Is there an existing alternative that I should consider? A cool templating engine maybe?

• E-Business Suite : Role of CHUNK_SIZE in Oracle Payroll

  - by Giri Mandalika

  Different batch processes in Oracle Payroll flow have the ability to spawn multiple child processes (or threads) to complete the work in hand. The number of child processes to fork is controlled by the THREADS parameter in APPS.PAY_ACTION_PARAMETERS view. THREADS parameter The default value for THREADS parameter is 1, which is fine for a single-processor system but not optimal for the modern multi-core multi-processor systems. Setting the THREADS parameter to a value equal to or less than the total number of [virtual] processors available on the system may improve the performance of payroll processing. However on the down side, since multiple child processes operate against the same set of payroll tables in HR schema, database may experience undesired consequences such as buffer busy waits and index contention, which results in giving up some of the gains achieved by using multiple child processes/threads to process the work. Couple of other action parameters, CHUNK_SIZE and CHUNK_SHUFFLE, help alleviate the database contention. eg., Set a value for THREADS parameter as shown below. CONNECT APPS/APPS_PASSWORD UPDATE PAY_ACTION_PARAMETERS SET PARAMETER_VALUE = DESIRED_VALUE WHERE PARAMETER_NAME = 'THREADS'; COMMIT; (I am not aware of any maximum value for THREADS parameter) CHUNK_SIZE parameter The size of each commit unit for the batch process is controlled by the CHUNK_SIZE action parameter. In other words, chunking is the act of splitting the assignment actions into commit groups of desired size represented by the CHUNK_SIZE parameter. The default value is 20, and each thread processes one chunk at a time -- which means each child process inserts or processes 20 assignment actions at any time. When multiple threads are configured, each thread picks up a chunk to process, completes the assignment actions and then picks up another chunk. This is repeated until all the chunks are exhausted. It is possible to use different chunk sizes in different batch processes. During the initial phase of processing, CHUNK_SIZE number of assignment actions are inserted into relevant table(s). When multiple child processes are inserting data at the same time into the same set of tables, as explained earlier, database may experience contention. The default value of 20 is mostly optimal in such a case. Experiment with different values for the initial phase by +/-10 for CHUNK_SIZE parameter and observe the performance impact. A larger value may make sense during the main processing phase. Again experimentation is the key in finding the suitable value for your environment. Start with a large value such as 2000 for the chunk size, then increment or decrement the size by 500 at a time until an optimal value is found. eg., Set a value for CHUNK_SIZE parameter as shown below. CONNECT APPS/APPS_PASSWORD UPDATE PAY_ACTION_PARAMETERS SET PARAMETER_VALUE = DESIRED_VALUE WHERE PARAMETER_NAME = 'CHUNK_SIZE'; COMMIT; CHUNK_SIZE action parameter accepts a value that is as low as 1 or as high as 16000. CHUNK SHUFFLE parameter By default, chunks of assignment actions are processed sequentially by all threads - which may not be a good thing especially given that all child processes/threads performing similar actions against the same set of tables almost at the same time. By saying not a good thing, I mean to say that the default behavior leads to contention in the database (in data blocks, for example). It is possible to relieve some of that database contention by randomizing the processing order of chunks of assignment actions. This behavior is controlled by the CHUNK SHUFFLE action parameter. Chunk processing is not randomized unless explicitly configured. eg., Set chunk shuffling as shown below. CONNECT APPS/APPS_PASSWORD UPDATE PAY_ACTION_PARAMETERS SET PARAMETER_VALUE = 'Y' WHERE PARAMETER_NAME = 'CHUNK SHUFFLE'; COMMIT; Finally I recommend checking the following document out for additional details and additional pay action tunable parameters that may speed up the processing of Oracle Payroll.     My Oracle Support Doc ID: 226987.1 Oracle 11i & R12 Human Resources (HRMS) & Benefits (BEN) Tuning & System Health Checks Also experiment with different combinations of parameters and values until the right set of action parameters and values are found for your deployment.

• Omni-directional light shadow mapping with cubemaps in WebGL

  - by Winged

  First of all I must say, that I have read a lot of posts describing an usage of cubemaps, but I'm still confused about how to use them. My goal is to achieve a simple omni-directional (point) light type shading in my WebGL application. I know that there is a lot more techniques (like using Two-Hemispheres or Camera Space Shadow Mapping) which are way more efficient, but for an educational purpose cubemaps are my primary goal. Till now, I have adapted a simple shadow mapping which works with spotlights (with one exception: I don't know how to cut off the glitchy part beyond the reach of a single shadow map texture): glitchy shadow mapping<<< So for now, this is how I understand the usage of cubemaps in shadow mapping: Setup a framebuffer (in case of cubemaps - 6 framebuffers; 6 instead of 1 because every usage of framebufferTexture2D slows down an execution which is nicely described here <<<) and a texture cubemap. Also in WebGL depth components are not well supported, so I need to render it to RGBA first. this.texture = gl.createTexture(); gl.bindTexture(gl.TEXTURE_CUBE_MAP, this.texture); gl.texParameteri(gl.TEXTURE_CUBE_MAP, gl.TEXTURE_MIN_FILTER, gl.LINEAR); gl.texParameteri(gl.TEXTURE_CUBE_MAP, gl.TEXTURE_MAG_FILTER, gl.LINEAR); for (var face = 0; face < 6; face++) gl.texImage2D(gl.TEXTURE_CUBE_MAP_POSITIVE_X + face, 0, gl.RGBA, this.size, this.size, 0, gl.RGBA, gl.UNSIGNED_BYTE, null); gl.bindTexture(gl.TEXTURE_CUBE_MAP, null); this.framebuffer = []; for (face = 0; face < 6; face++) { this.framebuffer[face] = gl.createFramebuffer(); gl.bindFramebuffer(gl.FRAMEBUFFER, this.framebuffer[face]); gl.framebufferTexture2D(gl.FRAMEBUFFER, gl.COLOR_ATTACHMENT0, gl.TEXTURE_CUBE_MAP_POSITIVE_X + face, this.texture, 0); gl.framebufferRenderbuffer(gl.FRAMEBUFFER, gl.DEPTH_ATTACHMENT, gl.RENDERBUFFER, this.depthbuffer); var e = gl.checkFramebufferStatus(gl.FRAMEBUFFER); // Check for errors if (e !== gl.FRAMEBUFFER_COMPLETE) throw "Cubemap framebuffer object is incomplete: " + e.toString(); } Setup the light and the camera (I'm not sure if should I store all of 6 view matrices and send them to shaders later, or is there a way to do it with just one view matrix). Render the scene 6 times from the light's position, each time in another direction (X, -X, Y, -Y, Z, -Z) for (var face = 0; face < 6; face++) { gl.bindFramebuffer(gl.FRAMEBUFFER, shadow.buffer.framebuffer[face]); gl.viewport(0, 0, shadow.buffer.size, shadow.buffer.size); gl.clear(gl.COLOR_BUFFER_BIT | gl.DEPTH_BUFFER_BIT); camera.lookAt( light.position.add( cubeMapDirections[face] ) ); scene.draw(shadow.program); } In a second pass, calculate the projection a a current vertex using light's projection and view matrix. Now I don't know If should I calculate 6 of them, because of 6 faces of a cubemap. ScaleMatrix pushes the projected vertex into the 0.0 - 1.0 region. vDepthPosition = ScaleMatrix * uPMatrixFromLight * uVMatrixFromLight * vWorldVertex; In a fragment shader calculate the distance between the current vertex and the light position and check if it's deeper then the depth information read from earlier rendered shadow map. I know how to do it with a 2D Texture, but I have no idea how should I use cubemap texture here. I have read that texture lookups into cubemaps are performed by a normal vector instead of a UV coordinate. What vector should I use? Just a normalized vector pointing to the current vertex? For now, my code for this part looks like this (not working yet): float shadow = 1.0; vec3 depth = vDepthPosition.xyz / vDepthPosition.w; depth.z = length(vWorldVertex.xyz - uLightPosition) * linearDepthConstant; float shadowDepth = unpack(textureCube(uDepthMapSampler, vWorldVertex.xyz)); if (depth.z > shadowDepth) shadow = 0.5; Could you give me some hints or examples (preferably in WebGL code) how I should build it?

• Customer owes me half my payment. Should I take ownership of his AWS account for charging? How?

  - by Cawas

  Background They paid me my first half (back in April 15th) before even we could get into an agreement. Very nice of him! Then I've finished the 2 weeks job of setting up the servers, using his AWS credentials he had just bought. I waited for another 2 weeks for everything settling up, and it was all running fine. He did what he needed with his sftp account, everyone were happy. Now, it has been almost 2 months since I've finished the job and I still didn't get the 2nd half. I must assume, it's not much money (about U$400, converted), but it would help me pay the bills at least. Heck, the Amazon bills they are paying are little less than that (for now). Measures I'm wondering how I can go to charge him now. First thought, of course, would be taking everything down and say "pay now, or be doomed". If that's not good enough, then I lost it. I have no contracts and I doubt I could get a law suit in this country for such a low value based only on emails. And I don't really want to get too agressive here - there might be a business chance in the future and I don't want to ruin it. Second though would be just changing the password. But then he probably could gain access again by some recovery means. That's where my question may mainly relay. How can I do it and not leaving any room for recovery from his side? I even got the first AWS "your account was created" mail from himself, showing me I could begin my job, back then. Lastly, do you have any other idea on what I can and what I should do in this case? Responding to Answers Please, consider reading the current answers and comments. This is not a very simple case. I've considered many, many options (including all lawful ones) before considering this ones I've listed here, and I am willing to take the loss and all that. That's not the point. The point is being practical here. I will call him again and talk about it. I will do terrorism on getting lawyers and getting contract. I am ready to go all forth while I have time and energy for it. But, in practice, there is this extra thing I can do to assure myself of the work I've done. I can basically take it back and delete everything! I'd only take his password because I can find no other way to do it within Amazon. Maybe, contacting Amazon and explaining the situation? I don't know. Give me ideas on this technical side! And thank everyone for the attention and helping me clarifying the issue so far! :)

• The Social Enterprise: Gangnam Style

  - by Mike Stiles

  Are only small and medium businesses able to put social strategies in place, generate consistent, compelling content for customers, and be nimble enough to listen and respond to the social communities they build? Or are enterprise organizations eagerly and effectively adopting social as well? It depends on whom inside the organization you ask. A study from Attensity looked at who “gets” social inside enterprise organizations. The results were unsurprising. Mostly, Generation X and Y employees who came of age with social as part of their lives and as a key communications vehicle understand it. Imagine being a 25-year-old at a company that bans employees from accessing Facebook at work. You may as well tell them they can’t use phones and must do all calculations on an abacus. To them, such policy is absent of real-world logic and signals to them the organization is destined to be the victim of an up-and-comer. After that, it’s senior management that gets social. You don’t get to be in senior management without reading a few things and paying attention. Most senior managers are well aware of the impact social has had and will have, though they may be unsure of what to do about it. The better ones will utilize those on the inside who do inherently know how to communicate and build virtual relationships using social. The very best will get the past out of the way for these social innovators, so the new communications can be enacted minus counterproductive dictums, double-clutching, meeting-creep, and all the other fading internal practices that water down content and impede change. Organizationally, the Attensity study found 81% of enterprise companies believe failing to embrace social will result in their being left behind. Yet our old friend fear still has many captive in its clutches. 79% feel overwhelmed by the volume of social data available, something a social technology partner with goal-oriented analytics expertise could go a long way toward alleviating. Then there’s the fear of social having a negative impact. This comes from a lack of belief in the product, the customer service, or both. The public uses social not to go out and slay brands. They’re using it to be honest. If the fear is that honesty will reflect badly on the brand, the brand has much bigger, broader problems than what happens on Facebook. Sadly, most enterprise organizations still see social as a megaphone, a one-way channel with which to hit people with ads. They either don’t understand social relationships, or don’t want any. The truly unenlightened manager will always say, “We help them by selling them our stuff.” “Brand affinity” is a term, it’s just not one assigned much value in enterprise organizations. Which brings us to Psy, the Korean performer whose Internet video phenom “Gangnam Style,” as of this writing, has been viewed 438,550,238 times on YouTube. It’s bigger than anything a brand will probably ever publish. Most brands would never have seen the point of making or publishing it. But a funny thing happened on the way to Internet success. The video literally doubled the stock price of Psy’s father’s software firm. NH Investment and Securities said, "The positive sentiment has attracted investors just because of the fact the company is owned by Psy's father and uncle.” The company wasn’t mentioned or seen in the video in any way, yet reaped tangible rewards just for being tangentially associated with it. Imagine your brand being visibly and directly responsible for such a smash and tell me it’s worthless. When enterprise organizations embrace the value of igniting passions, making people happier, solving their problems, informing them, helping them have fun, etc., then they will have fully embraced social, and will reap the brand affinity rewards of heightened awareness, brand loyalty and yes, sales.

• PowerShell and SMO – be careful how you iterate

  - by Fatherjack

  I’ve yet to have a totally smooth experience with PowerShell and it was late on Friday when I crashed into this problem. I haven’t investigated if this is a generally well understood circumstance and if it is then I apologise for repeating everything. Scenario: I wanted to scan a number of server for many properties, including existing logins and to identify which accounts are bestowed with sysadmin privileges. A great task to pass to PowerShell, so with a heavy heart I started up PowerShellISE and started typing. The script doesn’t come easily to me but I follow the logic of SMO and the properties and methods available with the language so it seemed something I should be able to master. Version #1 of my script. And the results it returns when executed against my home laptop server. These results looked good and for a long time I was concerned with other parts of the script, for all intents and purposes quite happy that this was an accurate assessment of the server. Let’s just review my logic for each step of the code at the top. Lines 1 to 7 just set up our variables and write out the header message Line 8 our first loop, to go through each login on the server Line 10 an inner loop that will assess each role name that each login has been assigned Line 11 a test to see if each role has the name ‘sysadmin’ Line 13 write out the login name with a bright format as it is a sysadmin login Line 17 write out the login name with no formatting It is quite possible that here someone with more PowerShell experience than me will be shouting at their screen pointing at the error I made but to me this made total sense. Until I altered the code, I altered lines 6 and 7 of code above to be: $c = $Svr.Logins.Count write-host “There are $c Logins on the server” This changed my output to look like this: This started alarm bells ringing – there are clearly not 13 logins listed So, let’s see where things are going wrong, edit the script so it looks like this. I’ve highlighted the changes to make Running this code shows me these results Our $n variable should count up by one for each login returned and We are clearly missing some logins. I referenced this list back to Management Studio for my server and see the Logins as below, where there are clearly 13 logins. We see a Login called Annette in SSMS but not in the script results so I opened that up and looked at its properties and it’s server roles in particular. The account has only public access to the server. Inspection of the other logins that the PowerShell script misses out show they too are only members of the public role. Right now I can’t work out whether there is a good reason for this and if it should be expected behaviour or not. Please spend a few minutes to leave a comment if you have an opinion or theory for this. How to get the full list of logins. Clearly I needed to get a full list of the logins so set about reviewing my code to see if there was a better way to iterate through the roles for each login. This is the code that I came up with and I think it is doing everything that I need it to. It gives me the expected results like this: So it seems that the ListMembers() method is the trouble maker in my first versions of the code. I would have expected that ListMembers should return Logins that are only members of the public role, certainly Technet makes no reference to it being left out in it’s Login.ListMembers details. Suffice to say, it’s a lesson learned and I will approach using it with caution in future circumstances.

• My shiny new gadget

  - by TechTwaddle

  About 3 months ago when I had tweeted (or twit?) that the HD7 could be my next phone I wasn’t a 100 percent sure, and when the HTC Mozart came out it was switch at first sight. I wanted to buy the Mozart mainly for three reasons; its unibody construction, smaller screen and the SLCD display. But now, holding a HD7 in my hand, I reminisce and think about how fate had its own plan. Too dramatic for a piece of gadget? Well, sort of, but seriously, this has been most exciting. So in short, I bought myself a HTC HD7 and am really loving it so far. Here are some pics (taken from my HD2 which now lies in a corner, crying),     Most of my day was spent setting up the device. Email accounts, Facebook, Marketplace etc. Since marketplace isn’t officially launched in India yet, my primary live id did not work. Whenever I tried launching marketplace it would say ‘marketplace is not currently supported in your country’. Searching the forums I found an easy work around. Just create a dummy live id with the country set to UK or US and log in to the device using this id. I was worried if the contacts and feeds from my primary live account would not be updated but that was not a problem. Adding another live account into the device does import your contacts, calendar and feeds from it. And that’s it, marketplace now works perfectly. I installed a few trial and free applications; haven’t checked if I can purchase apps though, will check that later and update this post. There is one issue I am still facing with the device, I can’t access the internet over GPRS. Windows Phone 7 only gives you the option to add an ‘APN’ and nothing else. Checking the connection settings on my HD2, I found out that there is also a proxy server I need to add to access GPRS, but so far I haven’t found a way to do that on WP7. Ideally HTC should have taken care of this, detect the operator and apply that operators settings on the device, but looks like that’s not happening. I also tried the ‘Connection Settings’ application that HTC bundled with the device, but it did nothing magical. If you’re reading this and know how to fix this problem please leave a comment. The next thing I did is install apps, a lot of apps. Read Engadget’s guide to essential apps for WP7. The apps and games I installed so far include Beezz (twitter app with push notifications), twitter (the official twitter app), Facebook, Youtube, NFS Undercover, Rocket Riot, Krashlander, Unite and the list goes on. All the apps run super smooth. The display looks fine indoors but I know it’s going to suck in bright sunlight. Anyhow, I am really impressed with what I’ve seen so far. I leave you with a few more photos. Have a great year ahead. Ciao!

• Blind As a Bat in Multi-Monitor Hell &ndash; Free Program Inside!

  - by ToStringTheory

  If you know me personally, then you probably know that I am going blind thanks to a rare genetic eye disease.  My eye disease has already been a huge detriment to my eyesight.  One of the big things to suffer is my ability to see small things moving fast right in front of me.  On a multi-monitor setup, this makes finding the cursor absolute hell. The Problem I’ll keep this short, as I’ve basically already told you what the problem is.  On my three monitor development computer, I am constantly losing the mouse during the day.  I had used the Microsoft accessibility mousefinder (press CTRL, and it pings around the mouse).  The problem with this is, there is only an effect around 50-100 PX around the mouse, and it is a very light gray, almost unnoticeable.. For someone like me, if I am not looking at the monitor when I click the CTRL button, I have to click it multiple times and dart my eyes back and forth in a futile attempt to catch a glimpse of the action…  I had tried other cursor finders, but none I liked… The Solution So what’s a guy to do when he doesn’t like his options?  MAKE A NEW OPTION…  What else should we as developers do, am I right?  So, I went ahead and made a mousefinder of my own, with 6 separate settings to change the effect.  I am releasing it here for anyone else that may also have problems finding their mouse at times. Some of its features include: Multiple options to change to achieve the exact effect you want. If your mouse moves while it is honing in, it will hone in on its current position. Many times, I would press the button and move my mouse at the same time, and many times, the mouse happened to be at a screen edge, so I would miss it. This program will restart its animation on a new screen if the mouse changes its screen while playing. Tested on Windows 7 x64 Stylish color changing from green to red. Deployed as a ClickOnce, so easy to remove if you don't like it. Press Right CTRL to trigger effect Application lives in notification area so that you can easily reach configuration or close it. To get it to run on startup, copy its application shortcut from its startmenu directory to the “Startup” folder in your startmenu. Conclusion I understand if you don’t download this…  You don’t know me and I don’t know you.  I can only say that I have honestly NOT added any virus’ or malware to the package. Yeah, I know it’s weird Download: ‘ToString(theory) Mousefinder.zip’ CRC32: EEBCE300 MD5: 0394DA581BE6F3371B5BA11A8B24BC91 SHA-1: 2080C4930A2E7D98B81787BB5E19BB24E118991C Finally, if you do use this application - please leave a comment, or email me and tell me what you think of it.

• Why Are We Here?

  - by Jonathan Mills

  Back in the early 2000s, Toyota had a vision of building the number one best selling minivan in North America. Their current minivan, the Sienna, was small, underpowered, and badly needed help.  Yuji Yokoya was given the job of re-engineering the Sienna. There was just one problem, Yuji, lived in Japan. He did not know the people or places that he would be engineering for. Believe it or not, Japan is nothing like North America. So, what does a chief engineer do in a situation like that? He packed up his team and flew halfway around the world. He made a commitment to drive through every state in the US, every province in Canada, and Mexico. He met the people and drove the roads that the Sienna would be driving. And guess what, what he learned on that trip revolutionized the Sienna. The innovations he made, sent the Sienna to number one. Why? Because he knew who he was building his product for. He knew, why he was there.Let me ask you this, do you know why you are building what you are building? As a member of a product team, can you tell me how your product will be used in the real world? As you are writing code, building test plans, writing stories, or any of the other project tasks, can you picture the face of a person who will be using what you are building? All to often, the answer to those questions is, no. Why is it important? Because, every day, project team members make assumptions. Over a given project, it is safe to say project team members will make thousands of assumptions about what they are doing. And all to often, those assumptions are not quite right. Its not that they are not good at their job, its just that they don’t really know why they are there.So, what to do? First and foremost, stop doing what you are doing. Yes, really. Schedule some time to go visit the people who will be using your product. Don’t invite them to you, go to them. Watch them work. Interact with them. Ask them questions. Maybe even try it out yourself. This serves two purposes. One, It shows them that you care about them. They will be far more engaged in your project if they feel like you care. And nothing says you care more that spending some time. Second, if gives you the proper frame of reference for you work. It gives you something tangible to go back to as you are building your product. As you make the thousands of assumptions that you will make over the life of your project, it gives you something to see in your mind that makes it real to you.Ultimately, setting a proper frame of reference is critical to the overall success of a project. The funny thing is, it really does not even take that long. In most cases, a 2-3 hour session will give you most of what you need to get the right insight. For the project, it will be the best 2 hours you could spend.

• How to upgrade a remote server from 8.10 to newer version?

  - by DisgruntledGoat

  I have a remote server still running Ubuntu 8.10 9.04 that I can only access via SSH. If I run apt-get update I get a bunch of 404 errors on the packages. I've asked a few questions on Server Fault but got nowhere. Here's what I've done: Run apt-get update which returns errors like: Err http://gb.archive.ubuntu.com intrepid/main Packages 404 Not Found [and same for many other packages] Run do-release-upgrade which returns: Checking for a new ubuntu release Failed Upgrade tool signature Failed Upgrade tool Done downloading extracting 'jaunty.tar.gz' Failed to extract Extracting the upgrade failed. There may be a problem with the network or with the server. Edited /etc/update-manager/release-upgrades and changed from Prompt=normal to Prompt=lts (as suggested here). Running do-release-upgrade after this returns: Checking for a new ubuntu release current dist not found in meta-release file No new release found (Updated) I have followed the advice in this question and changed /etc/apt/sources.list to refer to jaunty instead of intrepid. However, that distro is not online anymore either. A comment there says I have to upgrade in chronological order... So basically, it seems like I cannot upgrade because my current distro is out of date and not supported. Is there a way to upgrade direct to 10.x or 11.x? Note, as this is a server I only have command-line access. UPDATE 24/11: I have managed to upgrade from 8.10 to 9.04. Ubuntu's EOL Upgrades page provides some alternate URLs for apt sources. I also needed to update /var/lib/update-manager/meta-release to point to the old-releases server too. However, now I cannot upgrade from 9.04 to 9.10. Running do-release-upgrade produces the same error as #2 above, except it "Failed to fetch" (the URLs in meta-release are valid). The Ubuntu Jaunty upgrade page says it's necessary to upgrade using a CD image. I followed the instructions here, but it didn't work: A fatal error occurred Please report this as a bug and include the files /var/log/dist-upgrade/main.log and /var/log/dist-upgrade/apt.log in your report. The upgrade is now aborted. Your original sources.list was saved in /etc/apt/sources.list.distUpgrade. Traceback (most recent call last): File "/tmp/tmp.JLhTwVUugb/karmic", line 7, in sys.exit(main()) File "/tmp/tmp.JLhTwVUugb/DistUpgradeMain.py", line 132, in main if app.run(): File "/tmp/tmp.JLhTwVUugb/DistUpgradeController.py", line 1590, in run return self.fullUpgrade() File "/tmp/tmp.JLhTwVUugb/DistUpgradeController.py", line 1506, in fullUpgrade if not self.doPostInitialUpdate(): File "/tmp/tmp.JLhTwVUugb/DistUpgradeController.py", line 762, in doPostInitialUpdate self.quirks.run("PostInitialUpdate") File "/tmp/tmp.JLhTwVUugb/DistUpgradeQuirks.py", line 83, in run for plugin in self.plugin_manager.get_plugins(condition): File "/tmp/tmp.JLhTwVUugb/computerjanitor/plugin.py", line 167, in get_plugins filenames = self.get_plugin_files() File "/tmp/tmp.JLhTwVUugb/computerjanitor/plugin.py", line 120, in get_plugin_files basenames = [x for x in os.listdir(dirname) OSError: [Errno 2] No such file or directory: './plugins' It does say to report the bug, but since this is an old unsupported release I don't know if it's worth doing. However, is there a way round this, to upgrade from 9.04 to 9.10 (And then finally to 10.04 LTS.)

• Internet of Things Becoming Reality

  - by kristin.jellison

  The Internet of Things is not just on the radar—it’s becoming a reality. A globally connected continuum of devices and objects will unleash untold possibilities for businesses and the people they touch. But the “things” are only a small part of a much larger, integrated architecture. A great example of this comes from the healthcare industry. Imagine an expectant mother who needs to watch her blood pressure. She lives in a mountain village 100 miles away from medical attention. Luckily, she can use a small “wearable” device to monitor her status and wirelessly transmit the information to a healthcare hub in her village. Now, say the healthcare hub identifies that the expectant mother’s blood pressure is dangerously high. It sends a real-time alert to the patient’s wearable device, advising her to contact her doctor. It also pushes an alert with the patient’s historical data to the doctor’s tablet PC. He inserts a smart security card into the tablet to verify his identity. This ensures that only the right people have access to the patient’s data. Then, comparing the new data with the patient’s medical history, the doctor decides she needs urgent medical attention. GPS tracking devices on ambulances in the field identify and dispatch the closest one available. An alert also goes to the closest hospital with the necessary facilities. It sends real-time information on her condition directly from the ambulance. So when she arrives, they already have a treatment plan in place to ensure she gets the right care. The Internet of Things makes a huge difference for the patient. She receives personalized and responsive healthcare. But this technology also helps the businesses involved. The healthcare provider achieves a competitive advantage in its services. The hospital benefits from cost savings through more accurate treatment and better application of services. All of this, in turn, translates into savings on insurance claims. This is an ideal scenario for the Internet of Things—when all the devices integrate easily and when the relevant organizations have all the right systems in place. But in reality, that can be difficult to achieve. Core design principles are required to make the whole system work. Open standards allow these systems to talk to each other. Integrated security protects personal, financial, commercial and regulatory information. A reliable and highly available systems infrastructure is necessary to keep these systems running 24/7. If this system were just made up of separate components, it would be prohibitively complex and expensive for almost any organization. The solution is integration, and Oracle is leading the way. We’re developing converged solutions, not just from device to datacenter, but across devices, utilizing the Java platform, and through data acquisition and management, integration, analytics, security and decision-making. The Internet of Things (IoT) requires the predictable action and interaction of a potentially endless number of components. It’s in that convergence that the true value of the Internet of Things emerges. Partners who take the comprehensive view and choose to engage with the Internet of Things as a fully integrated platform stand to gain the most from the Internet of Things’ many opportunities. To discover what else Oracle is doing to connect the world, read about Oracle’s Internet of Things Platform.

  - by Maria Sandu

  Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Oracle is a place that brings together talented people from various countries and with a diversity of backgrounds. We often invite our employees to speak about their life at Oracle as we think It is important to share an insight into what working for our company looks like. This time we asked Stanislav to speak about his experience at Oracle. He is Technology Sales Manager at Oracle Russia. He joined the company in July 2011 as a Sales Representative for the Financial sector and had previously worked for another American IT company. He was promoted to a Management position in 2013. “I have been in this Industry for 15 years and I am now Technology Sales Manager, covering Database, BI and Fusion Middleware products. What I’ve learned in my role is that respect is one of the most important values a good professional should have. By respecting and embracing everyone’s opinions, we create a very good work environment that encourages innovation and change. It eventually leads to a stronger team where people listen to each other and value each other’s opinion. On the other hand, It is mandatory to have good knowledge about the area you work in and to continously seek to improve your expertise. Last but not least, working as a team is a top priority and It is something that I’ve learned at Oracle. There’s little you can achieve by yourself comparing to what you can do when you’re part of a team.” Stanislav shared the top three words that best describe his team and those were: professional, dynamic and smart. “The team I manage is a very professional, dynamic and smart one. I am really proud to work with such talented people! They are an asset to the Oracle business because they are the very best in the IT industry worldwide!” When asked why he would apply at Oracle if he was looking for a job, Stanislav responded “I would say because Oracle is a legend of the IT industry. It is a very dynamic company where you can fulfill your potential and gain extremely valuable knowledge. No doubt this is the number 1 IT company!” We invite you to explore our career opportunities on oracle.com/careers and to discover more stories about the life at Oracle on our blog.

• Drawing random smooth lines contained in a square [migrated]

  - by Doug Mercer

  I'm trying to write a matlab function that creates random, smooth trajectories in a square of finite side length. Here is my current attempt at such a procedure: function [] = drawroutes( SideLength, v, t) %DRAWROUTES Summary of this function goes here % Detailed explanation goes here %Some parameters intended to help help keep the particles in the box RandAccel=.01; ConservAccel=0; speedlimit=.1; G=10^(-8); % %Initialize Matrices Ax=zeros(v,10*t); Ay=Ax; vx=Ax; vy=Ax; x=Ax; y=Ax; sx=zeros(v,1); sy=zeros(v,1); % %Define initial position in square x(:,1)=SideLength*.15*ones(v,1)+(SideLength*.7)*rand(v,1); y(:,1)=SideLength*.15*ones(v,1)+(SideLength*.7)*rand(v,1); % for i=2:10*t %Measure minimum particle distance component wise from boundary %for each vehicle BorderGravX=[abs(SideLength*ones(v,1)-x(:,i-1)),abs(x(:,i-1))]'; BorderGravY=[abs(SideLength*ones(v,1)-y(:,i-1)),abs(y(:,i-1))]'; rx=min(BorderGravX)'; ry=min(BorderGravY)'; % %Set the sign of the repulsive force for k=1:v if x(k,i)<.5*SideLength sx(k)=1; else sx(k)=-1; end if y(k,i)<.5*SideLength sy(k)=1; else sy(k)=-1; end end % %Calculate Acceleration w/ random "nudge" and repulive force Ax(:,i)=ConservAccel*Ax(:,i-1)+RandAccel*(rand(v,1)-.5*ones(v,1))+sx*G./rx.^2; Ay(:,i)=ConservAccel*Ay(:,i-1)+RandAccel*(rand(v,1)-.5*ones(v,1))+sy*G./ry.^2; % %Ad hoc method of trying to slow down particles from jumping outside of %feasible region for h=1:v if abs(vx(h,i-1)+Ax(h,i))<speedlimit vx(h,i)=vx(h,i-1)+Ax(h,i); elseif (vx(h,i-1)+Ax(h,i))<-speedlimit vx(h,i)=-speedlimit; else vx(h,i)=speedlimit; end end for h=1:v if abs(vy(h,i-1)+Ay(h,i))<speedlimit vy(h,i)=vy(h,i-1)+Ay(h,i); elseif (vy(h,i-1)+Ay(h,i))<-speedlimit vy(h,i)=-speedlimit; else vy(h,i)=speedlimit; end end % %Update position x(:,i)=x(:,i-1)+(vx(:,i-1)+vx(:,i))/2; y(:,i)=y(:,i-1)+(vy(:,i-1)+vy(:,1))/2; % end %Plot position clf; hold on; axis([-100,SideLength+100,-100,SideLength+100]); cc=hsv(v); for j=1:v plot(x(j,1),y(j,1),'ko') plot(x(j,:),y(j,:),'color',cc(j,:)) end hold off; % end My original plan was to place particles within a square, and move them around by allowing their acceleration in the x and y direction to be governed by a uniformly distributed random variable. To keep the particles within the square, I tried to create a repulsive force that would push the particles away from the boundaries of the square. In practice, the particles tend to leave the desired "feasible" region after a relatively small number of time steps (say, 1000)." I'd love to hear your suggestions on either modifying my existing code or considering the problem from another perspective. When reading the code, please don't feel the need to get hung up on any of the ad hoc parameters at the very beginning of the script. They seem to help, but I don't believe any beside the "G" constant should truly be necessary to make this system work. Here is an example of the current output: Many of the vehicles have found their way outside of the desired square region, [0,400] X [0,400].

• ReSharper 8.0 EAP now available

  - by TATWORTH

  Originally posted on: http://geekswithblogs.net/TATWORTH/archive/2013/06/28/resharper-8.0-eap-now-available.aspxJetbrains have just released |ReSharper 8.0 Beta on their Early Access |Programme at http://www.jetbrains.com/resharper/whatsnew/?utm_source=resharper8b&utm_medium=newsletter&utm_campaign=resharper&utm_content=customersResharper 8.0 comes with the following new features:Support for Visual Studio 2013 Preview. Yes, ReSharper is known to work well with the fresh preview of Visual Studio 2013, and if you have already started digging into it, ReSharper 8.0 Beta is ready for the challenge.Faster code fixes. Thanks to the new Fix in Scope feature, you can choose to batch-fix some of the code issues that ReSharper detects in the scope of a project or the whole solution. Supported fixes include removing unused directives and redundant casts.Project dependency viewer. ReSharper is now able to visualize a project dependency graph for a bird's eye view of dependencies within your solution, all without compiling anything!Multifile templates. ReSharper's file templates can now be expanded to generate more than one file. For instance, this is handy for generating pairs of a main logic class and a class for extensions, or sets of partial files.Navigation improvements. These include a new action called Go to Everything to let you search for a file, type or method name from the same input box; support for line numbers in navigation actions; a new tool window called Assembly Explorer for browsing through assemblies; and two more contextual navigation actions: Navigate to Generic Substitutions and Navigate to Assembly Explorer.New solution-wide refactorings. The set of fresh refactorings is headlined by the highly requested Move Instance Method to move methods between classes without making them static. In addition, there are Inline Parameter and Pull Parameter. Last but not least, we're also introducing 4 new XAML-specific refactorings!Extraordinary XAML support. A plethora of new and improved functionality for all developers working with XAML code includes dedicated grid inspections and quick-fixes; Extract Style, Extract, Move and Inline Resource refactorings; atomic renaming of dependency properties; and a lot more.More accessible code completion. ReSharper 8 makes more of its IntelliSense magic available in automatic completion lists, including extension methods and an option to import a type. We're also introducing double completion which gives you additional completion items when you press the corresponding shortcut for the second time.A new level of extensibility. With the new NuGet-based Extension Manager, discovering, installing and uninstalling ReSharper extensions becomes extremely easy in Visual Studio 2010 and higher. When we say extensions, we mean not only full-fledged plug-ins but also sets of templates or SSR patterns that can now be shared much more easily.CSS support improvements. Smarter usage search for CSS attributes, new CSS-specific code inspections, configurable support for CSS3 and earlier versions, compatibility checks against popular browsers - there's a rough outline of what's new for CSS in ReSharper 8.A command-line version of ReSharper. ReSharper 8 goes beyond Visual Studio: we now provide a free standalone tool with hundreds of ReSharper inspections and additionally a duplicate code finder that you can integrate with your CI server or version control system.Multiple minor improvements in areas such as decompiling and code formatting, as well as support for the Blue Theme introduced in Visual Studio 2012 Update 2.
