• "Opportunity" to take over maintenance of a small internal website. What should I do?

  - by Dan

  I have been offered an "opportunity" to take over maintenance of a small internal website run by my group that provides information about schedules and photos of events the groups done. My manager sent me the link to the site and checked it out. The site looked clean and neat but loaded in ~5 seconds. I thought this was a little long considering the site really didn't contain a lot of content. This prompted me to take a look under the hood at the pages source code. To my horror it'd been totally hacked together using nested tables! I'm new so I really can't say no to this "opportunity" so what should I do with it? Every fiber of my being feels that the only correct thing to do is over hall the site using CSS, Div's, Span's and any other appropriate tags that a sane/good web developer would used to begin with instead of depending on the render incentive magic of tables. But I'd like to ask programmers with more experienced then me, who have been in this situation. What should I do? Is my only realistic option to leave the horror as is and only adjusting the content as requested? I'm really torn between good development and the corporate reality I'm part of. Is there some kind of middle ground where things can be made better even if they're not perfect? Thanks ahead of time.

• Rule of thumb for cost vs. savings for code re-use

  - by Styler

  Is it a good rule of thumb to always write code for the intent of re-using it somewhere down the road? Or, depending on the size of the component you are writing, is it better practice to design it for re-use when it makes sense with regards to time spent on it. What is a good rule of thumb for spending extra time on analysis and design on project components that have "some probability" of being needed later down the road for other things that may or may need this part. For example, if I have the need for project X to do things A, and B. A definitely needs to be written for re-use because it just makes sense to do so. B is very project specific at the moment, and I can hack it all together in a couple days to finish the project on time and give everyone kudos for being a great team, etc. Or if we say, lets spend a whole friggin' 2 weeks figuring out what project Y/Z might need this thing for and spend a load of extra time on on part B because someday we might need to use it on project Y/Z (where the savings will be realized). I'd imagine a perfect world situation would be a nicely crafted combination of project specific vs. re-use architected components given the project. However some code shops might feel it would be a great idea to write everything for the intention of using it at some point down the road.

• How can rotating release managers improve a project's velocity and stability?

  - by Yannis Rizos

  The Wikipedia article on Parrot VM includes this unreferenced claim: Core committers take turns producing releases in a revolving schedule, where no single committer is responsible for multiple releases in a row. This practice has improved the project's velocity and stability. Parrot's Release Manager role documentation doesn't offer any further insight into the process, and I couldn't find any reference for the claim. My first thoughts were that rotating release managers seems like a good idea, sharing the responsibility between as many people as possible, and having a certain degree of polyphony in releases. Is it, though? Rotating release managers has been proposed for Launchpad, and there were some interesting counterarguments: Release management is something that requires a good understanding of all parts of the code and the authority to make calls under pressure if issues come up during the release itself The less change we can have to the release process the better from an operational perspective Don't really want an engineer to have to learn all this stuff on the job as well as have other things to take care of (regular development responsibilities) Any change of timezones of the releases would need to be approved with the SAs and: I think this would be a great idea (mainly because of my lust for power), but I also think that there should be some way making sure that a release manager doesn't get overwhelmed if something disastrous happens during release week, maybe by have a deputy release manager at the same time (maybe just falling back to Francis or Kiko would be sufficient). The practice doesn't appear to be very common, and the counterarguments seem reasonalbe and convincing. I'm quite confused on how it would improve a project's velocity and stability, is there something I'm missing, or is this just a bad edit on the Wikipedia article? Worth noting that the top voted answer in the related "Is rotating the lead developer a good or bad idea?" question boldly notes: Don't rotate.

• Upcoming events : OBUG Connect Conference 2012

  - by Maria Colgan

  The Oracle Benelux User Group (OBUG) have given me an amazing opportunity to present a one day Optimizer workshop at their annual Connect Conference in Maastricht on April 24th. The workshop will run as one of the parallel tracks at the conference and consists of three 45 minute sessions. Each session can be attended stand alone but they will build on each other to allow someone new to the Oracle Optimizer or SQL tuning to come away from the conference with a better understanding of how the Optimizer works and what techniques they should deploy to tune their SQL. Below is a brief description of each of the sessions Session 7 - 11:30 am Oracle Optimizer: Understanding Optimizer StatisticsThe workshop opens with a discussion on Optimizer statistics and the features introduced in Oracle Database 11g to improve the quality and efficiency of statistics-gathering. The session will also provide strategies for managing statistics in various database environments. Session 27 -  14:30 pm Oracle Optimizer: Explain the Explain PlanThe workshop will continue with a detailed examination of the different aspects of an execution plan, from selectivity to parallel execution, and explains what information you should be gleaning from the plan. Session 47 -  15:45 pm Top Tips to get Optimal Execution Plans Finally I will show you how to identify and resolving the most common SQL execution performance problems, such as poor cardinality estimations, bind peeking issues, and selecting the wrong access method.   Hopefully I will see you there! +Maria Colgan

• Logistics of code reuse (OOP)

  - by Ominus

  One of the driving points behind OOP is code reuse. I am curious about the actual logistics of this and how others both in team or solo handle it. For example lets say you have 5 projects you have worked on and between them you have a ton of classes that you think would be useful in other projects. How do you store them? Are they just in the normal project repository or do you break out the relevant classes and have them (as now copies) in another unique source repository that only houses code pieces that are intended to be reused? How do you go about finding or even knowing that there is a good piece of code out there that you should reuse? It's easier if your solo because you remember that you have coded something similar but even then it becomes kind of a stretch. If there is some way that you are storing these pieces of code do you then also have them indexed and searchable by tag or something. I fear that it just boils down to some tribal knowledge that you just know that for situation A i need solution B and we have a good piece of code that already can help here. A bit verbose but I hope you get what I am aiming at. If you think of a better way to make the question clearer please have at it :) TIA!

• JavaScript loaded external content SEO

  - by user005569871

  I wonder what is the best way to have Javascript loaded content indexed by search engines. I know that search engines don't execute Javascript, but I am thinking more of an progressive enchantment. I am creating a responsive website, and on the home page I will have some sections about most visited products and recommended product that I plan to load depending on the device detected. These products will be in sliders with thumbnail images and names of the products. If mobile is detected slider content will not load, ant the link to the external page will be shown. I know that external content will be indexed via link to those resources. Where will the users be directed from search in this case? To the external page or home page? Will it be bad for SEO if I show only product names on front page so they can be indexed and hide them with CSS? What is the best way to index that content and possibly direct users from search to home page? Also, i've seen the Ajax crawling but iI would like not to use that if there is any better way.

• Finding header files

  - by rwallace

  A C or C++ compiler looks for header files using a strict set of rules: relative to the directory of the including file (if "" was used), then along the specified and default include paths, fail if still not found. An ancillary tool such as a code analyzer (which I'm currently working on) has different requirements: it may for a number of reasons not have the benefit of the setup performed by a complex build process, and have to make the best of what it is given. In other words, it may find a header file not present in the include paths it knows, and have to take its best shot at finding the file itself. I'm currently thinking of using the following algorithm: Start in the directory of the including file. Is the header file found in the current directory or any subdirectory thereof? If so, done. If we are at the root directory, the file doesn't seem to be present on this machine, so skip it. Otherwise move to the parent of the current directory and go to step 2. Is this the best algorithm to use? In particular, does anyone know of any case where a different algorithm would work better?

• Windows 7 ReadyBoost - What File System To Use With Flash Card/Drive?

  - by Boris_yo

  NTFS, exFAT or FAT32? I know that FAT32 has a limit of 4GB transfer per file, but is it faster and better than NTFS or exFAT? Since Windows 7 by itself uses NTFS, it remains logical to format flash card/drive with NTFS file system, however will NTFS or even exFAT be fine for flash card/drive? P.S. In case i decide to use SD flash card, what should i do if it is already plugged in and i decide to use another SD flash card in order to transfer photos? What will happen if i take out suddenly ReadyBoost SD flash card?

• Oracle OpenWorld Session: “Business Driven Development with BPM: Lessons from the Real World”

  - by Ajay Khanna

  One of key values that BPM promises is “Business Empowerment”. People closest to the processes, who participate in the process every day, are the ones who know most about the process. These are the people who run day-to-day operations, people who triage customer issues, people who envision improvements and innovations. It is, therefore, imperative that when a company decides to use BPM technology to automate their business processes, business people take the driver’s seat. BPM is not an IT only project. Oracle BPM suite has been designed keeping this core tenet of BPM, Business Empowerment, in mind. The result is business user centered design of Process Composer. Process Composer is designed to let business users document their processes, analyze them using simulation, create web forms, specify business rules and even run them in testing mode using process player, to see if the designed process meets their needs. This does not mean that IT has no role in this process. In fact, Oracle BPM Suite has made it very easy for Business and IT to collaborate. The same process can be shared among business, and IT stakeholders and each can collaborate to create model-driven, process based executable applications. A process may need to integrate with multiple systems via various mechanisms, and IT leads system and data integration effort. IT helps fine tune the performance of process applications and ensures that the deployment of process application meets scalability and failover standards. In this session, we saw Harish Gaur and Satya Narayanan from Oracle demonstrate roles Business and IT play in BPM projects and how Oracle BPM Suite enables business and IT collaboration to design and automate process based applications. They also discussed real life customer stories. Some key takeaways from this session: There are no IT projects, only business initiatives, requiring IT support Identify high impact processes – critical, better BPM ROI Identify key metrics to measure process performance Align business with IT layer

• Inserting Keynote slides into a Pages document

  - by Ian Turner

  I have a number of training documents which are formed from a word processor file and a slideshow. I'd like to be able to keep them together, ideally by inserting the slides from Keynote into Pages. Is there any way of doing this quickly? So far I have tried Applescript with little success. I can drag and drop the slides one at a time but it is a bit slow, and I've tried turning the slideshow into and dragging it into Pages but this only pulls in the first slide. Does anyone have any better ideas?

• How to verify that all files are intact prior to install?

  - by Kalle H. Väravas

  I'm working on my CMS (in PHP platform) for a long time now. The main program is done and I'm currently developing the Installer part. Installation itself will be fairly simple: Upload all files Verify that the "content/" dir has correct permissions Check if ALL files are intact and not modified [This is the subject of this question] Insert the config data and first settings Run install (Generate all DB tables and insert sample data etc.) Now the question-mark is at step 3. How do I verify ALL files? Verification itself should compare all CMS root-directories files against a list from remote location. List should contain filename, filesize and filetype. This way the user can check, that there are no unnecessary or corrupted files, that could indicated a breach in the software. I have seen some software installers do that, but I cannot find any right now and there for I'm clueless on the most optimal method for this. Of course there always is a simple array trick, but there surely must be a better and faster method?!

• Overwhelmed by complex C#/ASP.NET project in Visual Studio 2008

  - by Darren Cook

  I have been hired as a junior programmer to work on projects that extend existing functionality in a very large, complex solution. The code base consists of C#, ASP.NET, jQuery, javascript, html and xml. I have some knowledge of all these in addition to fair knowledge of object-oriented programming and its fundamental concepts of inheritance, abstraction, polymorphism and encapsulation. I can follow code up through its base classes, interfaces, abstract classes and understand a large part of the code that I read while doing this. However, this solution is so humongous and so many things get tied together whenever I navigate through the code that I feel absolutely overwhelmed. I often find myself unable to fully follow everything that is going on with objects being serialized, large amounts of C# and javascript operating on the same pages and methods being called from template files that consist mainly of markup. I love learning about code, but trying to deal with this really stresses me out. Additionally, I do know that a significant amount of unit testing has been done but I know nothing about unit testing or how to utilize it. Any advice anyone could offer me regarding dealing with a large code base while using Visual Studio 2008 would be greatly appreciated. Are there tools that I can use to help get a handle on what is going on? Perhaps there are things even in Visual Studio that I am not aware of. How can I follow the code to low level functionality in order to get a better grasp of what is going on at a high level?

• How can I refresh a document I have open in Excel in read-only mode?

  - by RoboShop

  I have an Excel document that is stored on a SharePoint Server, which I always have open on my computer in read-only mode because I need to refer to it. Every so often, in order to get the latest changes, I have to close down the file and reload it again. Are there any options within Excel 2007 which allow me to simply refresh a document I have open in read-only mode to the latest version on the server? Better still, is there a way where this could be done dynamically, without me having to hit refresh?

• Slow Starting DHCP Client Service - HP Thin Clients

  - by Ryan

  We have recently began adding XPe thin clients to our domain in preperation for a new citrix environment. One thing that has been picked up on in testing is that they appear slow to boot. The issue manifest's it's self as the classic "Applying Computer Settings..." screen we are all used to seeing. After digging into the issue it appears the DHCP Client service is taking some time to load on boot, this varies but I would estimate it can take around 1 minute in some cases. I've eliminated the classic issues, DHCP is responding correctly and in quick time. DNS is not the cause and GPO's are applying promptly. A simple workaround is to assign the client a static IP which work's great so the TCP/IP servies are obviously firing up quickly, just not DHCP Client. Does anyone have any idea's on how I may be able to improve the service start time? Keen to find a better solution before I get my arm twisted into setting up 250 thin clients with static addressing!

• New Feature! Automatic Categories for Geekswithblogs.net

  - by Jeff Julian

  One of the features we have been working on is a way to categorize posts without the need of all our bloggers getting on the same page with what categories we have and making them select the categories.  Johnny Kauffman, one of our team members at AJI Software, developed what we call the Sherlock Project over the past few months.  Sherlock is a category suggestion engine based on the content within the posts.  Now, after a post is published, Sherlock will investigate the content and come up with the suggested categories that content fits in.  This will now allow you to go to the specific topics you are interested in and see all the related posts. This is just the beginning, so many more opportunities will arise now that we have our content organized.  One of the first features I will be adding is RSS feeds for each category and sub category.  If you are into ALM, we will have a feed for that! I hope you enjoy these and the engine will continue to get better as we start testing the data.  I hope you are as excited about this as I am :D.  Technorati Tags: Geekswithblogs.net,Categories,Sherlock

• Exchange 2007 backup / restore

  - by Matt

  To explain my situation I have a exchange 2007 server and I have recently upgraded to SP2 so that I can use windows server backup to take an "exchange aware" backup of the server. Is there an easy way of restoring this data onto a second server to which I have pre-installed server 2008 / exchange 2007 without upsetting my current exchange server set-up. Also is there a better way to do this, such as running one as a fall over should the primary exchange server develop a fault. I am still new to all this so please excuse any stupidity in my questions. Thanks in advance for any help and assistance

• Using AdSense to show ads to logged-in users

  - by John

  I know that you can grant authorization permissions to Google AdSense so that it can 'log in' and see what other logged in users can see (e.g. in a private forum), so that the ads it displays are better targetted. Extending this principle further: I am making a site which will show completely different content for each individual user (i.e. not 'common' content like a forum in which everybody sees essentially the same thing). You could think of this content as similar to the way each Facebook user has a different news feed, but it is the 'same' page. Complicating things further, the URLs for this site will be simple, e.g. '/home' and '/somepage', and will not usually include unique identifiers to differentiate between users (e.g. '/home?user=32i42'). My questions are: Is creating an account purely for AdSense to log in to the site with worth it in this case, seeing as it will be seeing it's own 'personalized' version and not any other user's? More importantly: is that against the Google AdSense Terms of Service? (I can't seem to figure that one out) How would you go about this problem?

• Best Small Linux Distribution for rDesktop

  - by d2jxp

  What would be the best linux distribution to use just for the purpose of rDesktop? We're trying to decide if we should get rid of old computers or just use them as thin-clients to connect to virtual Windows 7 machines on our network. I would like something with as little bloat as possible and can be run from a USB flash drive. I have tried SliTaz, ThinStation, and Pixil from Century Software. SliTaz has been my favorite so far but I still want to know if there's something better that's also easily customizable.

• T61, NVidia, Ubuntu 9.10 == Video problems

  - by David Lazar

  Hi, Upgraded to latest Ubuntu, currently 9.10. Videos used to work fine. Now, playing videos using VLC or any other media player shows them 'sepia' tinged when playing. This is annoying. I remember this used to happen on occasion (after resuming from suspect), and I forget what I fiddled with to make it better. Does anyone have the method to force video to render correctly with this combination? It happens even after a reboot. Thanks

• Migrating an Active Directory domain controller to AWS

  - by Xavier Hutchinson

  I am required to migrate a Active Directory server into AWS with a couple other servers (SQL and IIS) to create a dev and test environment for our network / development. My plan at this time is to simply rebuild the Active Directory server in AWS from scratch - which is quite time consuming indeed! I was wondering if anyone had a recommendation as to a better and more efficient approach of migrating a copy of a physical Active Directory server to the cloud? The server is Windows Server 2012. Thank you!

• Is DevCon.exe still the best way to restart/power cycle USB ports after resuming from hibernation in

  - by ProfessionalAmateur

  I have a USB broadband card on my Windows 7 laptop. It loathes resuming from hibernation properly. Back in the XP days I would issue a call devcon.exe from the command prompt and restart the selected ports (Saves you having to manually unplug and plug back in your USB devices). Ive been trying this is Windows 7, but the UAC keeps getting in the way. I'll start a command prompt. Issue the devcon command, but UAC asks me if I really want to do this, when I click yes it opens a different command prompt and launches the command. After the command completed this new prompt window closes faster than the speed of light and I cannot see the results. So Im thinking there has to be a better way to do this in the Vista/Win7 world...?

• Generalise variable usage inside code

  - by Shirish11

  I would like to know if it is a good practice to generalize variables (use single variable to store all the values). Consider simple example Strings querycre,queryins,queryup,querydel; querycre = 'Create table XYZ ...'; execute querycre ; queryins = 'Insert into XYZ ...'; execute queryins ; queryup = 'Update XYZ set ...'; execute queryup; querydel = 'Delete from XYZ ...'; execute querydel ; and Strings query; query= 'Create table XYZ ... '; execute query ; query= 'Insert into XYZ ...'; execute query ; query= 'Update XYZ set ...'; execute query ; query= 'Delete from XYZ ...'; execute query ; In first case I use 4 strings each storing data to perform the actions mentioned in their suffixes. In second case just 1 variable to store all kinds the data. Having different variables makes it easier for someone else to read and understand it better. But having too many of them makes it difficult to manage. Also does having too many variables hamper my performance?

• Is it possible to to have all pre-unity effects in latest ubuntu?

  - by iamserious

  I've been an Ubuntu dilettante for a long, long time. It is not my primary OS but I've always had it on all my laptops and desktop machines for over 8 years now. What I really, really like(d) about ubuntu (or linux, for that matter) was the effects - desktop cube, wobbly windows and other such "cool" effects. Needless to say, I was heartbroken with Unity. I gave it the benefit of doubt and tried to like it, tried to love it. Stuck with it for over a year. But I recently came to the conclusion that unity is really not for me. I want my old ubuntu back, with all it's eye candy effects. I tried messing around with ccsm but it only seemed to make the matters worse. Now, I could just install the old version of ubuntu - but getting my bamboo pen and Nvidia to work with it is a son of a.. anyway, the point is, old version of ubuntu is outdated to work with my newer machines. I'd rather have a new version of ubuntu but without unity- I don't know what the eye candy stuff is called - and so my question is this - Is it possible to rid ubuntu of unity and get all the eye candy stuff and if it is not possible, can you please advice me what other linux supports all the effects, please? I've searched high and low for unity alternatives but didn't find any satisfactory solutions; so I think my question is mainly about what other linux flavour is better suited for the task - sorry if it is out of topic.

• Is there a performance difference between Cat5 and Cat6 keystone blocks?

  - by Scott Anderson

  I'm going to be wiring my home for ethernet soon, and I've already decided that I want to use Cat6 cable to do it (faster speeds, better performance, etc). During the installation, I'd like to add wall-plates to certain rooms in my house, and the keystone blocks look like the best option for me. My question is: I've seen different keystone blocks on many cabling websites, some say Cat5e and some say Cat6. The Cat6 ones are slightly more expensive. Is there any noticeable performance gain from using a Cat6 keystone? To me, it just seems like the keystone really wouldn't matter, since it's basically like putting an RJ-45 end on a cable. Can I buy the cheaper Cat5e keystone blocks and still have the performance that Cat6 cable will give me? Thanks!

• Why don't C++ Game Developers use the boost library?

  - by James

  So if you spend any time viewing / answering questions over on Stack Overflow under the C++ tag, you will quickly notice that just about everybody uses the boost library; some would even say that if you aren't using it, you're not writing "real' C++ (I disagree, but that's not the point). But then there is the game industry, which is well known for using C++ and not using boost. I can't help but wonder why that is. I don't care to use boost because I write games (now) as a hobby, and part of that hobby is implementing what I need when I am able to and using off-the-shelf libraries when I can't. But that is just me. Why don't game developers, in general, use the boost library? Is it performance or memory concerns? Style? Something Else? I was about to ask this on stack overflow, but I figured the question is better asked here. EDIT : I realize I can't speak for all game programmers and I haven't seen all game projects, so I can't say game developers never use boost; this is simply my experience. Allow me to edit my question to also ask, if you do use boost, why did you choose to use it?
