• iOS chat application design, sending/relaying the message over to the end user

  - by AyBayBay

  I have a design question. Let us say you were tasked with building a chat application, specifically for iOS (iOS Chat Application). For simplicity let us say you can only chat with one person at a time (no group chat functionality). How then can you achieve sending a message directly to an end user from phone A to phone B? Obviously there is a web service layer with some API calls. One of the API calls available will be startChat(). After starting a chat, when you send a message, you make another async call, let us call it sendMessage() and pass in a string with your message. Once it goes to the web service layer, the message gets stored in a database. Here is where I am currently stuck. After the message gets sent to the web service layer, how do we then achieve sending/relaying the message over to the end user? Should the web server send out a message to the end user and notify them, or should each client call a receiveMessage() method periodically, and if the server side has some info for them it can then respond with that info? Finally, how can we handle the case in which the user you are trying to send a message to is offline? How can we make sure the end user gets the packet when he moves back to an area with signal?

• Why is <my site url> not indexed by search engines? [closed]

  - by Henrik Erlandsson

  was indexed fine until about a year ago. The only thing I can think of is that search engines throw up at using h5 before h4, or that some person (fantasizing now) has reported my site as unsafe to every search engine. However, I'm not here to speculate. The site validates, and has an RSS feed on the front page, for Pat Morita's sake! To me, it looks like the kind of site search engines would feast on. It's got more than a dozen blogs on it, if nothing else. Hah. :) I was thinking you could identify basically what has changed in search engines (currently, google, yahoo, bing which used to work fine) the last year to make them not find news and blog articles on this site. The site was submitted to Google, oh, way back in 2006. With online crawler tests I get mixed results, some crawlers index fine, some go blank. I don't really know which ones are reliable and am looking to you guys for advice on that. Yes, I am prepared to again verify my site with Google and upload a sitemap, but that's not the topic here. I really would first like to know what change on the site last year could make search engines not index it. (Yees, the robots.txt is fine. Should be nothing to discourage bots there.) It's a very intriguing problem. One which I have yet to find the reason for but would like to know the reason for. Any and all input appreciated, but I would heavily enjoy pertinent advice the most. ;) Edit: Some google searches that don't show up include - aca630 All of which are posted in the news and blogs that are on the front page there. Now, these search terms are extremely specific as the term in is almost unique on the web and ACA630 is also a very qualified search term that can't be confused with mainstream search terms.

• Data Movement and the Decision Matrix

  - by BuckWoody

  Maybe it’s my military background, or maybe I’ve always had this predilection, but I like to use two devices when I need to make a complex decision: A checklist and a decision matrix. I like to use a checklist because it ensures that I remember the big bits of what I need to do, and brings up questions or areas that I didn’t think about when evaluating options for the decision. And the decision matrix – that’s the thing I use to actually lay out those options. It’s simply a spreadsheet-like grid (I use Excel, but paper and pencil works as well) that lays out the requirements or advantages for the decision across the top, and the options I have on the left-hand side. Then in the “cells” I put whether or not that option on the left will meet the requirement in that column. I then simply “weight” each cell to organize the choices by best-fit. The right answer (or answers) will float right to the top. I was asked yesterday about options for moving data in SQL Server to another system. There are just dozens of ways to do this, from bcp to Replication, each with certain advantages and costs. But asking the questions for the top row first helped me show the person that it isn’t a particular technology that is important, it’s laying out those requirements and thinking about which elements are more important than the other. For instance, is it more important to have the data moved all the time, or is it OK if that happens once in a while? Does the data have to move in two directions or just one? All of these will help that answer jump right out. Try it sometime – it’s a great learning exercise, since it will force you to focus on filling out the matrix. The answer is out there, Neo.

• Another big year for the ADF EMG at OOW12

  - by Chris Muir

  Oracle Open World 2012 has only just started, but in one way it's just finished!  All the ADF EMG's OOW content is over for another year! The unique highlight this year for me was the first ever ADF EMG social night held on Saturday, where I finally had the chance to meet so many ADF community members who I've known over the internet, but never met in person.  What?  You didn't get an invite?  Oh well, better luck next year ;-) Seriously our budget was limited, so in the happy-dictatorship sort of way I had to limit RSVPs to just 40 people.  Hopefully next year we can do something bigger and better for the wider community. Following directly on from the Saturday social night the ADF EMG ran a full day of sessions at the user group Sunday.  I wont go over the content again, but to say thank you very much to all our presenters and helpers, including Gert Poel, Pitier Gillis, Aino Andriessen, Simon Haslam, Ken Mizuta, Lucas Jellema and the FMW roadshow team, Ronald van Luttikhuizen, Guido Schmutz, Luc Bors, Aino Andriessen and Lonneke Dikmans. Also special thanks must go to Doug Cockroft and Bambi Price for their time and effort in organizing the ADF EMG room behind the scenes via the APOUC. To be blunt Doug and Bambi really do deserve serious thanks because they had to wear a lot of Oracle politics behind the scenes to get the rooms organized (oh, and deal with me fretting too! ;-). Finally thanks to all the members and OOW delegates for turning up and supporting the group on the day.  In the end the ADF EMG exists for you, and I hope you found it worthwhile. Onto 2013 (oh, and the rest of OOW12 ;-)

• How do I make money from my FOSS while staying anonymous?

  - by user21007

  Let's say that: You have created a FOSS project that other people find useful, perhaps useful enough to donate to or pay for modifications to be done. It is a perfectly legitimate and innocuous software project. It has nothing to do with cryptography as munitions, p2p music, or anything likely to lead to a search warrant or being sued. You want your involvement to stay anonymous or pseudonymous. You would like to receive some money for your efforts, if people are willing. Is that possible, and if so, how could it be done? When I talk about anonymity, I realize that it is necessary to define the extent. I am not talking about Wikileaks style 20 layers of proxies worth of anonymity. I would expect a 3 letter agency to be able to identify the person easily. What is wanted is shielding from commercial competitors or random people, who would not be expected to be able to get the financial intermediary to divulge your details just by asking for them. Why would you want to stay anonymous? I can think of several valid reasons, maybe you operate a stealth mode startup and don't want to give your competitors clues as to the technology you are using. Maybe it is a project that has nothing to do with your daily job, is not developed there, but the company you work for has an unfair (and possibly unenforceable) policy stating that any coding you do is owned by them. Maybe you just value your privacy. For what it's worth, you intend to pay the relevant taxes in your country on any donations.

• What exactly does the condition in the MIT license imply?

  To quote the license itself: Copyright (C) [year] [copyright holders] Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software. I am not exactly sure what the bold part implies. Lets say that I'm creating some library, and I license it under the MIT license. Someone decides to fork that library and to create a closed-source, commercial version. According to the license, he should be free to do that. However, what does he additionally need to do under those terms? Credit me as the creator? I guess the "above copyright notice" refers to the "Copyright (C) [..." part, but, wouldn't that list me as the author of his code (although I technically typed out the code)? And wouldn't including the "permission notice" in what is now his library practically license it under the same conditions that I licensed my own library in? Or, am I interpreting this incorrectly? Does that refer to my obligations to include the copyright and the permission notice?

• website attack form submission triggering emails related questions

  - by IberoMedia

  We are experiencing website attacks that trigger the submission of a form, and send alert emails. Normal process of form submission is to fill up a couple of text fields, and when the user is redirected, the next page processes $_POST. If $_POST exists, then the email to intended form recipients is triggered. What is happening right now, we are receiving the email of the form submission, three emails at a time with same information. The information per email is the same, but not all of the spam emails contain the same information, each batch of triggered emails has unique information. The form has no captcha, and if possible we would like to keep it this way. The website has worked fine and had no spamming problems until today. We have monitoring software for the website, but whoever is submitting this form over and over is not being recorded by the tracking software WHY IS THIS? IS THE PERSON ACTUALLY VISITING THE WEBSITE? The only suspicious visit tracked was on November 10th, and this record ALSO shows three forms submitted (this is how I identified possible first visit by attacker). Then no incidents until today. WHAT IS THE GOAL of the spam attack? Is the attacker expecting us to respond to the bogus emails? What can they achieve with repeated submission of form Why are three emails triggered in the row? Is this indicative that they may be using a script? This is a PHP website. Is there a way for a client to view the PHP code of a page? Thank you

• Create device receive SMS parse to text ( SMS Gateway )

  - by Chris Okyen

  I want to use a server as a device to run a script to parse a SMS text in the following way. I. The person types in a specific and special cell phone number (Similar to Facebook’s 32556 number used to post on your wall) II. The user types a text message. III. The user sends the text message. IV. The message is sent to some kind of Device (the server) or SMS Gateway and receives it. V. The thing described above that the message is sent to then parse the test message. I understand that these three question will mix Programming and Server Stuff and could reside here or at DBA.SE How would I make such a cell phone number (described in step I) that would be sent to the Device? How do I create the device that then would receive it? Finally, how do I Parse the text message? I don't want to pay for cloud space, server scripting stuff or server space; I want to just use a free webserver to do this totally free - meaning I will have to do more on my own... My question can be seen in more depth in this visual flowchart

• Which web site gives the most accurate indication of a programmer's capabilities?

  - by Jerry Coffin

  If you were hiring programmers, and could choose between one of (say) the top 100 coders on topcoder.com, or one of the top 100 on stackoverflow.com, which would you choose? At least to me, it would appear that topcoder.com gives a more objective evaluation of pure ability to solve problems and write code. At the same time, despite obvious technical capabilities, this person may lack any hint of social skills -- he may be purely a "lone coder", with little or no ability to help/work with others, may lack mentoring ability to help transfer his technical skills to others, etc. On the other hand, stackoverflow.com would at least appear to give a much better indication of peers' opinion of the coder in question, and the degree to which his presence and useful and helpful to others on the "team". At the same time, the scoring system is such that somebody who just throws up a lot of mediocre (or even poor answers) will almost inevitably accumulate a positive total of "reputation" points -- a single up-vote (perhaps just out of courtesy) will counteract the effects of no fewer than 5 down-votes, and others are discouraged (to some degree) from down-voting because they have to sacrifice their own reputation points to do so. At the same time, somebody who makes little or no technical contribution seems unlikely to accumulate a reputation that lands them (even close to) the top of the heap, so to speak. So, which provides a more useful indication of the degree to which this particular coder is likely to be useful to your organization? If you could choose between them, which set of coders would you rather have working on your team?

• Agile Data Book from O'Reilly Media

  Originally posted on: http://geekswithblogs.net/Compudicted/archive/2013/07/01/153309.aspxAs part of my ongoing self-education and approaching of some free time, yeah, both is a must for every IT person and geek! I have carefully examined the latest trends in the Computersphere with whatever tools I had at my disposal (nothing really fancy was used) and came to a conclusion that for a database pro the *hottest* topic today is undoubtedly the #BigData and all the rapidly growing and spawning ecosystem around it. Having recently immersed myself into the NoSQL world (let me tell here right away NoSQL means Not Only SQL) one book really stood out of the crowd: Book site: http://shop.oreilly.com/product/0636920025054.doDespite being a new book I am sure it will end up on the tables of many Big Data Generalists.In a few dozen words, it is primarily for two reasons:1) The author understands that a  typical business today cannot wait for a Data Scientist for too long to deliver results demanding as usual a very quick turnaround on investments (ROI), and 2) The book covers all the needed and proven modern brick and mortar offerings to get the job done by a relatively newcomer to the Big Data World.It certainly enables such a professional to grow and expand based on the acquired knowledge, and one can truly do it very fast.

• Why The Athene Group Chose Fusion CRM

  - by Tony Berk

  A guest post by Vikas Bhambri, Managing Partner, The Athene Group This year, The Athene Group (www.theathenegroup.com) celebrated our tenth anniversary. The company has accomplished a lot in ten years overcoming a number of hurdles and challenges to have grown organically to a 150+ person global company with offices in the US, UK, and India and customers in the US, Canada, and Europe. Now more than ever with the current global landscape from an economic and competitive standpoint it was vital that we make some changes to remain successful for the next ten years. There were two key initiatives that we discussed internally that would enable us to successfully accomplish this – collaboration and the concept of “insight to action”. With our existing Oracle CRM On Demand platform we had components of this but not the full depth and breadth that we were looking for. When we started to discuss Fusion CRM we immediately saw several next generation tools that would embrace these two objectives. For a consulting and development organization the collaboration required between business development and consulting delivery is as important as the collaboration required during the projects between the project delivery and account management teams. The Activity Streams functionality in Fusion CRM immediately addressed the communication of key discussion topics and exchanges around our clients. Of course when we saw the Oracle Social Network (which is part of our Fusion CRM roadmap) we were blown away. The combination OSN and our CRM is going to make us more effective as we discuss and work cohesively on client engagements – ensuring mutual success for both Athene and our clients. When we looked at “insight to action” we saw that we had a great platform when folks were at their desks, unfortunately a lot of our business development and consulting folks are on the road. The Fusion Mobile Sales and Fusion Outlook Desktop provide information to our teams when they are on the go. So that they can provide real-time information and react to real-time information provided by their peers. We are in the early stages of our transformative experience with Fusion CRM but we believe the platform along with our people and processes are going to help us achieve our goals in the future.

• Recommendations for a web-based help system

  - by ggkmath

  Hi Experts, I'm putting together a fairly large GUI. I'm a tech person, but more on the hardware side, not software. I'm wondering what software package would be best suited to enable me to generate a web-based help-system. Preferably it takes care of a lot of coding, allowing me to focus on the content. For example, the user would click on a link in the GUI when they have a question, that brings them to a web-based Help Guide, for example, providing an overview of how to use the GUI, perhaps a searchable index (key-word based index), table of contents, etc, for navigating through the Help Guide. My first thought was to program everything in XHTML using Dreamweaver, but my layout requirements are fairly modest (just figures and text, maybe a few equations), and I'd prefer not to spend a lot of time concentrating on the programming. Was wondering if any software existed that made generating web-based navigatable pages easy to create/publish. Again, I'm not really a programmer, so if there's something obvious out there, I'm probably not aware of it. Any advice much appreciated! Thanks in advance.

• Restoring GRUB2 on Software RAID 0 using LiveCD after Windows 7 wiped it

  - by unknownthreat

  I have installed Ubuntu 10.10 on my system. However, I need to install Windows 7 back, and I expect that it would alter GRUB and it did. Right now, my partition on my Software RAID 0 looks like this: nvidia_acajefec1 is Ubuntu 10.10 and nvidia_acajefec3 is Windows 7. I've been following some guides around and I am always stuck at GRUB not able to detect the usual RAID content. I've tried running: sudo grub > root (hd0,0) GRUB complains it couldn't find my hard disk. So I tried: find (hd0,0) And it complains that it couldn't find anything. So I tried: find /boot/grub/stage1 It said "file not found". Here's the text from the console: ubuntu@ubuntu:~$ grub Probing devices to guess BIOS drives. This may take a long time. [ Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists the possible completions of a device/filename. ] grub> root (hd0,0) root (hd0,0) Error 21: Selected disk does not exist grub> find /boot/grub/stage1 find /boot/grub/stage1 Error 15: File not found Fortunately, I got one person suggesting that what I've been trying to do is for GRUB Legacy, not GRUB2. So I went to the suggested website, ** (http://grub.enbug.org/Grub2LiveCdInstallGuide) **try to look around, and try: ubuntu@ubuntu:~$ sudo fdisk -l Unable to seek on /dev/sda This is just the step 2 of the instruction in the http://grub.enbug.org/Grub2LiveCdInstallGuide and I cannot proceed because it cannot seek /dev/sda. However, ubuntu@ubuntu:~$ sudo dmraid -r /dev/sdb: nvidia, "nvidia_acajefec", stripe, ok, 488397166 sectors, data@ 0 /dev/sda: nvidia, "nvidia_acajefec", stripe, ok, 488397166 sectors, data@ 0 So what now? Do you have an idea for how to make fdisk see my RAID array on live cd (Ubuntu 10.10)? Honestly, I am lost, very lost in trying to restore GRUB2 on this software RAID 0 system right now.

• @CodeStock 2012 Review: Leon Gersing ( @Rubybuddha ) - "You"

  "YOU"Speaker: Leon GersingTwitter: @Rubybuddha Site: http://about.me/leongersing I honestly had no idea what I was getting in to when I sat down in to this session. I basically saw the picture of the speaker and knew that it would be a good session. I was completely wrong; it was the BEST SESSION of CodeStock 2012.  In fact it was so good, I texted another coworker attending the conference to get over and listen to Leon. Leon took on the concept of growth in the software development community. He specifically referred David Hansson in his ability to stick to his beliefs when the development community thought that he was crazy for creating Ruby on Rails. If you do not know this story Ruby on Rails is one of the fastest growing web languages today. In addition, he also touched on the flip side of this argument in that we must be open to others ideas and not discard them so quickly because we all come from differing perspectives and can add value to a project/team/community. This session left me with two very profound concepts/quotes: “In order to learn you must do it badly in front of a crowed and fail.” - @Rubybuddha I can look back on my career so far and say that he is correct; I think I have learned the most after failing, especially when I achieved this failure in front of other. “Experts must be able to fail.” - @Rubybuddha I think we can all learn from our own mistakes but we can also learn from others. When respected experts fail it is a great learning opportunity for the entire team as well as the person who failed. When expert admit mistakes and how they worked through them can be great learning tools for other developers so that they know how to avoid specific scenarios and if they do become stuck in the same issue they will know how to properly work their way out of them.

• JavaScript 3D space ship rotation

  - by user36202

  I am working with a fairly low-level JavaScript 3D API (not Three.js) which uses euler angles for rotation. In most cases, euler angles work quite well for doing things like aligning buildings, operating a hovercraft, or looking around in the first-person. However, in space there is no up or down. I want to control the ship's roll, pitch, and yaw. To do that, some people would use a local coordinate system or a permenant matrix or quaternion or whatever to represent the ship's angle. However, since I am not most people and am using a library that deals exclusively in euler angles, I will be using relative angles to represent how to rotate the ship in space and getting the resulting non-relative euler angles. For you math nerds, that means I need to convert 3 euler angles (with Y being the vertical axis, X representing the pitch, and Z representing a roll which is unaffected by the other angles, left-handed system) into a 3x3 orientation matrix, do something fancy with the matrix, and convert it back into the 3 euler angles. Euler to matrix to euler. Somebody has posted something similar to this on SO (http://stackoverflow.com/questions/1217775/rotating-a-spaceship-model-for-a-space-simulator-game) but he ended up just working with a matrix. This will not do for me. Also, I am using JavaScript, not C++. What I want essentially are the functions do_roll, do_pitch, and do_yaw which only take in and put out euler angles. Many thanks.

• How do you get past the Analysis to Paralysis when working on a new project?

  - by Cape Cod Gunny

  I've been struggling with how to get my project going. I've got an old software package that is in need of desparate rewrite. I haven't compiled the source code since 2004. It still sells, it's stable but does require the “Run this program in compatibility mode for:” on a lot of the newer windows systems. It's also one of those hard coded 640 X 480 screen resolution programs. Yuck! I can't seem to get started with this rewrite. I'm constantly fiddling around with different things. I'll play around with different fluid layouts for a while. Then I start looking around at how the main menu should work/look. I quickly find out that there's this thing called "Cool Bars" and I'll spend hours playing with that. Then I start thinking about stuff like "Oh I need to make sure that the screen sizes are preserved so when the application gets relaunched it remebers how the screens were positioned." Which leads to what happens if they have two monitors? Which leads to what happens if they have a quad screen? Yikes it's got to stop. I have always been a slow starter. I think about stuff long and hard up front. This has always plagued me. Once I get my mind made up then bam... I'm off and running. I'm looking for advice from some other one-person software companies that can help someone like me get off to a quicker start?

• CA For A Large Intranet

  - by Tim Post

  I'm managing what has become a very large intranet (over 100 different hosts / services) and will be stepping down from my role in the near future. I want to make things easy for the next victim person who takes my place. All hosts are secured via SSL. This includes various portals, wikis, data entry systems, HR systems and other sensitive things. We're using self signed certificates which worked o.k. in the past, but are now problematic because: Browsers make it harder for users to understand exactly what is going on when a self signed certificate is encountered, much less accept them. Putting up a new host means 100 phone calls asking what "Add an exception" means What we were doing is just importing the self signed certs when we set up a new workstation. This was fine when we only had a dozen to deal with, but now its just overwhelming. Our I.T. Department has classified this as ya all's problem, all we get from them is support for switch and router configurations. Beyond the user having connectivity, everything else is up to the intranet administrators. We have a mix of Ubuntu and Windows workstations. We'd like to set up our own self signed CA root, which can sign certificates for each host that we deploy on the intranet. Client browsers would of course be told to trust our CA. My question is, would this be dangerous and would we be better off going with intermediate certificates from someone like Verisign? Either way, I still have to import the root for the intermediate CA, so I really don't see what the difference is? Other than charging us money, what would Verisign be doing that we could not, beyond protecting the root CA cert so it can't be used to make forgeries?

• Most effective way to do daily standup meeting when a few people are remote

  - by Burhan Ali

  I am a software developer in a small team of seven. We are not an Agile (with a big 'A') team but are experimenting with some aspects of agile. One of these is the daily "standup" meeting. The difficulty here is that for two days of the week we have at least one person working from home so the full team isn't available in the same room. What is the best way to carry out a daily standup in this situation? Some facts that may be relevant: We all work in a single open plan room. We use Skype in our company. We don't have any video conferencing capability. We all work the same hours so there are no timezone complexities involved. The development manager is one of the people who works from home one day a week. Things we have tried: Conference call using Skype: This is tricky for those in the office because you can hear people speak in the room and then a split second later through the headset. This can e very distracting. Conference phone: Awful experience. Hard to get them to work and poor quality audio. Text-based updates using Skype. This is not as engaging and is no different than just firing off a status email in the morning. I have seen other questions about remote collaboration but they are mainly about completely remote teams and/or teams that span multiple time zones. We are not affected by either of these problems. What can we do to make our standup meetings better in these circumstances?

• Can I distribute a software with the following permission notice

• Is individual code ownership important?

  - by Jim Puls

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

• About online game servers and how to handle data

  - by TreantBG

  So my question isn't about what technology to use or how to do this or that, but a more general question. I'm currently developing a action third person shooter. With elements of RPG - weapon,armor upgrades and items. Players will be able to create new games or join old ones. So my question is how to create the game server that players will play in. I have two ideas on my mind. The player who made the game is the server. All data passes trough him and he send this data to the server updating the database of the players with their XP points kills/deaths score and other. Or my host machine is the server, the player who made the game just will open new instance on my host and will be like client. And all players send their input data to the host, the host updates the game and send response back to client for any new changes like where is the enemy and other. And if i choose option 1 is there a chance the host to change the game content and manipulate the game results? (I think there is but i'm not sure) And if i choose option 2 isn't that raising the response time and potentially the game lag? or maybe there is another option?

• How Can I Effectively Interview an Oracle Candidate?

  - by Tim Medora

  First, I browsed through SO for matching questions and didn't find one, but please point me in the right direction if this exact question has already been asked. I work with and around programmers of various skill levels on various platforms. I would consider my skills to be strong in terms of relational database design, query development, and basic performance tuning and administration. I'm mid-level when it comes to database theory. My team is looking to me to ensure that we have the best talent on staff, in this case, an engineer experienced in Oracle administration. To me, a well-rounded database administrator, regardless of platform, should also be competent in developing against the database so that is also a requirement. However my database skills are centralized around SQL Server 200x with experience in a few other products like SAP MaxDB, Access, and FoxPro. How can I thoroughly assess the skills of an Oracle engineer? I can ask high-level database theory questions and talk about routine tasks that are common across platforms, but I want to dig deep enough that I can be confident in the people I hire. Normally, I would alternate very specific questions that have a right/wrong answer with architectural questions that might have several valid answers. Does anyone have an interview template, specific questions, or any other knowledge that they can share? Even knowing the meaningful Oracle-related certifications would be a help. Thank you. EDIT: All the answers have been very helpful so far and I have given upvotes to everyone. I'm surprised that there are already 3 close votes on this question as "off topic". To be clear, I am specifically asking how a MS SQL Server engineer (like myself) can effectively interview a person with different but symbiotic skills. The question has already received specific, technical answers which have improved my own database design and programming skills. If this is more appropriate as a community wiki, please convert it.

• HTG Explains: What Is RSS and How Can I Benefit From Using It?

  - by Jason Fitzpatrick

  If you’re trying to keep up with news and content on multiple web sites, you’re faced with the never ending task of visiting those sites to check for new content. Read on to learn about RSS and how it can deliver the content right to your digital doorstep. In many ways, content on the internet is beautifully linked together and accessible, but despite the interconnectivity of it all we still frequently find ourselves visiting this site, then that site, then another site, all in an effort to check for updates and get the content we want. That’s not particular efficient and there’s a much better way to go about it. Imagine if you will a simple hypothetical situation. You’re a fan of a web comic, a few tech sites, an infrequently updated but excellent blog about an obscure music genre you’re a fan of, and you like to keep an eye on announcements from your favorite video game vendor. If you rely on manually visiting all those sites—and, let’s be honest, our hypothetical example has a scant half-dozen sites while the average person would have many, many, more—then you’re either going to be wasting a lot of time checking the sites every day for new content or you’re going to be missing out on content as you either forget to visit the sites or find the content after it’s not as useful or relevant to you. RSS can break you free from that cycle of either over-checking or under-finding content by delivering the content to you as it is published. Let’s take a look at what RSS is how it can help.

• Microsoft Tag Tagged Me

  - by Brian Schroer

  I got EXTREMELY lucky last week and won an HP Mini 311 notebook from a Microsoft Tag Twitter contest. I did my required tweet to enter last Tuesday, and one hour later received notification that I had won the weekly drawing. Apparently you can tweet up to 500 times (I pity the followers of those who do that), so it was really lucky that I won, and I sympathize with those who had been really trying. If you would like to try your luck, there are seven weekly prizes left, and you can find out about the contest here: http://tag.microsoft.com/ttcontest.aspx For a free PC, I thought it was the least I could do to find out what Microsoft Tag is. I was vaguely aware of those pastel-y triangle-y square things that look like someone put one of Don Johnson’s Miami Vice outfits through a shredder, and knew that the company I work for (one of the world’s largest consumer products companies) was looking into putting them on our products, packaging and advertising, but didn’t know much more about the technology. I thought they were just an improvement over bar codes, and would be used in retail store scanners, but I was mistaken. These tags are meant to be scanned by consumers using their mobile phones, to get instant access to information, websites, reviews, etc. Scanning a tag can open a web page, import a contact card, or dial a phone number, play a video… Tag reader software can be installed on Windows Mobile, iPhone, Symbian, Blackberry, Android, J2ME, and other phones (and I suspect that it will be available for Windows Phone 7 also :). There are built-in tracking, metrics and analysis tools, to help companies using Tag make decisions about their marketing expenditures. (And they don’t have to look Miami Vice-y – They can be customized to reflect the personality of the person or a brand.) Looks like interesting stuff. You can find out more at http://tag.microsoft.com.
