  • South Florida Code Camp 2010 &ndash; VI &ndash; 2010-02-27

    - by Dave Noderer
    Catching up after our sixth code camp here in the Ft Lauderdale, FL area. Website at: http://www.fladotnet.com/codecamp. For the 5th time, DeVry University hosted the event which makes everything else really easy! Statistics from 2010 South Florida Code Camp: 848 registered (we use Microsoft Group Events) ~ 600 attended (516 took name badges) 64 speakers (including speaker idol) 72 sessions 12 parallel tracks Food 400 waters 600 sodas 900 cups of coffee (it was cold!) 200 pounds of ice 200 pizza's 10 large salad trays 900 mouse pads Photos on facebook Dave Noderer: http://www.facebook.com/home.php#!/album.php?aid=190812&id=693530361 Joe Healy: http://www.facebook.com/devfish?ref=mf#!/album.php?aid=202787&id=720054950 Will Strohl:http://www.facebook.com/home.php#!/album.php?aid=2045553&id=1046966128&ref=mf Veronica Gonzalez: http://www.facebook.com/home.php#!/album.php?aid=150954&id=672439484 Florida Speaker Idol One of the sessions at code camp was the South Florida Regional speaker idol competition. After user group level competitions there are five competitors. I acted as MC and score keeper while Ed Hill, Bob O’Connell, John Dunagan and Shervin Shakibi were judges. This statewide competition is being run by Roy Lawsen in Lakeland and the winner, Jeff Truman from Naples will move on to the state finals to be held at the Orlando Code Camp on 3/27/2010: http://www.orlandocodecamp.com/. Each speaker has 10 minutes. The participants were: Alex Koval Jeff Truman Jared Nielsen Chris Catto Venkat Narayanasamy They all did a great job and I’m working with each to make sure they don’t stop there and start speaking at meetings. Thanks to everyone involved! Volunteers As always events like this don’t happen without a lot of help! The key people were: Ed Hill, Bob O’Connell – DeVry For the months leading up to the event, Ed collects all of the swag, books, etc and stores them. He holds meeting with various DeVry departments to coordinate the day, he works with the students in the days  before code camp to stuff bags, print signs, arrange tables and visit BJ’s for our supplies (I go and pay but have a small car!). And of course the day of the event he is there at 5:30 am!! We took two SUV’s to BJ’s, i was really worried that the 36 cases of water were going to break his rear axle! He also helps with the students and works very hard before and after the event. Rainer Haberman – Speakers and Volunteer of the Year Rainer has helped over the past couple of years but this time he took full control of arranging the tracks. I did some preliminary work solicitation speakers but he took over all communications after that. We have tried various organizations around speakers, chair per track, central team but having someone paying attention to the details is definitely the way to go! This was the first year I did not have to jump in at the last minute and re-arrange everything. There were lots of kudo’s from the speakers too saying they felt it was more organized than they have experienced in the past from any code camp. Thanks Rainer! Ray Alamonte – Book Swap We saw the idea of a book swap from the Alabama Code Camp and thought we would give it a try. Ray jumped in and took control. The idea was to get people to bring their old technical books to swap or for others to buy. You got a ticket for each book you brought that you could then turn in to buy another book. If you did not have a ticket you could buy a book for $1. Net proceeds were $153 which I rounded up and donated to the Red Cross. There is plenty going on in Haiti and Chile! I don’t think we really got a count of how many books came in. I many cases the books barely hit the table before being picked up again. At the end we were left with a dozen books which we donated to the DeVry library. A great success we will definitely do again! Jace Weiss / Ratchelen Hut – Coffee and Snacks Wow, this was an eye opener. In past years a few of us would struggle to give some attention to coffee, snacks, etc. But it was always tenuous and always ended up running out of coffee. In the past we have tried buying Dunkin Donuts coffee, renting urns, borrowing urns, etc. This year I actually purchased 2 – 100 cup Westbend commercial brewers plus a couple of small urns (30 and 60 cup we used for decaf). We got them both started early (although i forgot to push the on button on one!) and primed it with 10 boxes of Joe from Dunkin. then Jace and Rachelen took over.. once a batch was brewed they would refill the boxes, keep the area clean and at one point were filling cups. We never ran out of coffee and served a few hundred more than last  year. We did look but next year I’ll get a large insulated (like gatorade) dispensing container. It all went very smoothly and having help focused on that one area was a big win. Thanks Jace and Rachelen! Ken & Shirley Golding / Roberta Barbosa – Registration Ken & Shirley showed up and took over registration. This year we printed small name tags for everyone registered which was great because it is much easier to remember someone’s name when they are labeled! In any case it went the smoothest it has ever gone. All three were actively pulling people through the registration, answering questions, directing them to bags and information very quickly. I did not see that there was too big a line at any time. Thanks!! Scott Katarincic / Vishal Shukla – Website For the 3rd?? year in a row, Scott was in charge of the website starting in August or September when I start on code camp. He handles all the requests, makes changes to the site and admin. I think two years ago he wrote all the backend administration and tunes it and the website a bit but things are pretty stable. The only thing I do is put up the sponsors. It is a big pressure off of me!! Thanks Scott! Vishal jumped into the web end this year and created a new Silverlight agenda page to replace the old ajax page. We will continue to enhance this but it is definitely a good step forward! Thanks! Alex Funkhouser – T-shirts/Mouse pads/tables/sponsors Alex helps in many areas. He helps me bring in sponsors and handles all the logistics for t-shirts, sponsor tables and this year the mouse pads. He is also a key person to help promote the event as well not to mention the after after party which I did not attend and don’t want to know much about! Students There were a number of student volunteers but don’t have all of their names. But thanks to them, they stuffed bags, patrolled pizza and helped with moving things around. Sponsors We had a bunch of great sponsors which allowed us to feed people and give a way a lot of great swag. Our major sponsors of DeVry, Microsoft (both DPE and UGSS), Infragistics, Telerik, SQL Share (End to End, SQL Saturdays), and Interclick are very much appreciated. The other sponsors Applied Innovations (also supply code camp hosting), Ultimate Software (a great local SW company), Linxter (reliable cloud messaging we are lucky to have here!), Mediascend (a media startup), SoftwareFX (another local SW company we are happy to have back participating in CC), CozyRoc (if you do SSIS, check them out), Arrow Design (local DNN and Silverlight experts),Boxes and Arrows (a local SW consulting company) and Robert Half. One thing we did this year besides a t-shirt was a mouse pad. I like it because it will be around for a long time on many desks. After much investigation and years of using mouse pad’s I’ve determined that the 1/8” fabric top is the best and that is what we got!   So now I get a break for a few months before starting again!

  • Building Great-Looking, Usable Apps: A two-day workshop applying Oracle’s best UX practices in ADF

    - by mvaughan
    By Misha Vaughan, Oracle Applications User ExperienceI have been with Oracle for more than 12 years. It is a company that has granted me extraordinary creative freedom to help deliver compelling experiences for customers.I am beyond proud to talk about one of the experiences we just took for a test drive. Recently, we delivered a first-of-its-kind, three-team collaboration, train-the-trainer event in Reading, U.K., on building great-looking, usable apps based on Oracle Fusion Applications -- using the ADF tool kit. A new kind of workshopKevin Li, Platform Product Director, asked the Oracle Applications User Experience VP, Jeremy Ashley, if the team had anything to help partners and customers build applications that looked like Fusion. He was receiving this request from European partners and customers.Some quick conversations ensued, and the idea for the workshop was born: We would conduct an experiment.  We would work with feedback from the key Platform Technology Solutions (PTS) trainers under Andre Pavanello, Director, Platform Technology Solutions, in Europe, Middle East, and Africa. We would partner with the ADF team lead by Grant Ronald, Director of Product Management, title> and leverage the Applications UX expertise in Ashley’s team.The goal: Create a pilot workshop that in two days would explain to an ADF developer how to leverage the next-generation user experience best-practices developed for Fusion Apps. Why? Customers who need integrations with Oracle Fusion Applications, who are looking for custom applications that need to co-exist with Fusion, or who quite simply want a next-generation design for a custom app, need their solutions to reflect the next-generation research and design.Building an event for an ADF developerThe biggest hurdle was figuring out where to start.  How far into user experience country do you take an ADF developer? How far into ADF do you need to go if you are a UX professional?After some time in the UX kitchen, the workshop recipe looked like this: Mix equal parts: Fusion user experience design principles and functional design patterns The art and science behind UX How to wireframe designs that you can build in Fusion How to translate those designs into an ADF application Ultan O’Broin, Director of Global User Experience, explaining the trouble ticket wireframe design exerciseLynn Munsinger, Senior Group Product Manager, explaining the follow-on trouble ticket ADF coding exercise For spice, add:•    Debra Lilley, Fujitsu and ACE director, showcasing some of the latest ADF design work in the new face of Fusion Applications •    Partner show-and-tell of example apps they have built with FMW and ADF that are dynamic, beautiful, and interactive.Debra Lilley, Oracle ACE Director and Fujitsu Fusion Champion on the new face of Fusion built with ADF and Fusion extensibility with composers as a window into “the possible”?The taste testThis first go-round of the workshop was aimed squarely at ADF developers and partners.  We were privileged to have participation and feedback from:•    Sten Vesterli, Scott/Tiger S. A., Denmark•    John Sim, Fishbowl Solutions, UK•    Josef Huber, Primus Delphi Group, Munich•    Thaddaus Weindl, Primus Delphi, Group , Munich•    Praveen Pillalamarri, EiS Technologies, Bangalore•    Balaji Kamepalli, EiS Technologies, Bangalore•    Plinio Arbizu, Services & Processes Solutions S. A., Mexico•    Yannick Ongena, infoMENTUM, UK•    Jakub Ciszek, infoMENTUM, UK•    Mauro Flores, infoMENTUM, UK•    Matteo Formica, infoMENTUM, UKRichard Bingham, Oracle, Mauro Flores and Matteo Formica, infoMENTUMWhy is this so exciting?  Oracle has invested heavily in the research and development of the Oracle Fusion Applications user experience. This investment has been and continues to be applied across the product lines. Now, we finally get to teach customers and partners how to take advantage of this investment for custom solutions.This event was a pilot to test-drive the content, as well as a train-the-trainer event that our EMEA colleagues will be using with partners who want to build with Fusion Apps design patterns.What did attendees think?"I liked most the science stuff, like eye-tracking, design patterns and best-practice (color, contrast),” Josef Huber said. “It was a very good introduction to UI design, and most developers and project managers are very bad in that.  So this course would be good for all developers and even project managers." Team Anonymous: John Sim, Fishbowl Solutions, Flavius Sana, Oracle, Josef Huber, infoMENTUM, Mireille Duroussaud, Oracle. Winners of the wireframing design exercise.  Sten Vesterli, of Scott/Tiger, said he attended to learn techniques he could use in his own projects. He wants to ensure that his applications better meet the needs of his users, and he said sessions during the workshop on user interface design and wireframing were most useful to him.  “Go to this event to learn the art and science of good user interfaces from people who really know how to do it,” he said.Sten Vesterli, Scott/Tiger, Angelo Santagata, Oracle Plinio Arbizu said the workshop fulfilled his goals, thanks to the recommendations given in how to design user interfaces to facilitate the adoption of applications among the final users. “The workshop combined these recommendations with an exercise that improved the technical comprehension, permitting the usage of JDeveloper to set forth our solutions,” he said. He added: “The first session that I really enjoyed was the five Fusion design principles. It was incredible to discover how these simple principles were included in an inherit manner in Fusion Applications, and I had been using many of them applying only ADF components.  Another topic that I enjoyed a lot was the eight recommendations about the visual design of UIs. The issues that were raised in that lesson are unknown to the developers and of great value to achieve an attractive presentation layer to the end users.  Participate in this workshop, and include these usability features in your projects and in this manner not only to facilitate and improve the user productivity, but also to distinguish you as a professional who takes advantage fully of the functionalities offered by Oracle technology. Praveen Pillalamarri came to the workshop to learn about the difficulties faced in UI and UX development, and how this can be resolved with the help of ADF.  He also appreciated the opportunity to talk with other individuals who came to the workshop. Pillalmarri said, “The way we looked at things in terms of work and projects were sharpened.  UI and UX design knowledge shared by you was quite interesting, especially the minute things which we ignored in the UI or UX design.” Plinio Arbizu, Services & Processes Solutions S. A., Richard Bingham, Oracle, Balaji Kamepalli, & Praveen Pillalamarri, EiS TechnologiesReady to spread the wordIn EMEA, Oracle customers and partners have access to three world-class trainers via Platform Technology Solutions: Mireille Duroussaud, Flavius Sana, and Angelo Santagata. Contact Andre Pavanello if you like to experience this workshop firsthand, or you have customers or partners who would benefit from the training.We are looking to bring the event to the U.S. in spring 2013. If you have interest in this kind of a workshop, leave a comment below. For those who want to follow the action, join the ADF Enterprise Methodology Group run by Oracle’s Chris Muir. Ask questions and continue with the conversation in this forum, or check blogs.oracle.com/usableapps for topics emerging from the workshop.

  • The Sitemap Paradox

    - by Jeff Atwood
    We use a sitemap on Stack Overflow, but I have mixed feelings about it. Web crawlers usually discover pages from links within the site and from other sites. Sitemaps supplement this data to allow crawlers that support Sitemaps to pick up all URLs in the Sitemap and learn about those URLs using the associated metadata. Using the Sitemap protocol does not guarantee that web pages are included in search engines, but provides hints for web crawlers to do a better job of crawling your site. Based on our two years' experience with sitemaps, there's something fundamentally paradoxical about the sitemap: Sitemaps are intended for sites that are hard to crawl properly. If Google can't successfully crawl your site to find a link, but is able to find it in the sitemap it gives the sitemap link no weight and will not index it! That's the sitemap paradox -- if your site isn't being properly crawled (for whatever reason), using a sitemap will not help you! Google goes out of their way to make no sitemap guarantees: "We cannot make any predictions or guarantees about when or if your URLs will be crawled or added to our index" citation "We don't guarantee that we'll crawl or index all of your URLs. For example, we won't crawl or index image URLs contained in your Sitemap." citation "submitting a Sitemap doesn't guarantee that all pages of your site will be crawled or included in our search results" citation Given that links found in sitemaps are merely recommendations, whereas links found on your own website proper are considered canonical ... it seems the only logical thing to do is avoid having a sitemap and make damn sure that Google and any other search engine can properly spider your site using the plain old standard web pages everyone else sees. By the time you have done that, and are getting spidered nice and thoroughly so Google can see that your own site links to these pages, and would be willing to crawl the links -- uh, why do we need a sitemap, again? The sitemap can be actively harmful, because it distracts you from ensuring that search engine spiders are able to successfully crawl your whole site. "Oh, it doesn't matter if the crawler can see it, we'll just slap those links in the sitemap!" Reality is quite the opposite in our experience. That seems more than a little ironic considering sitemaps were intended for sites that have a very deep collection of links or complex UI that may be hard to spider. In our experience, the sitemap does not help, because if Google can't find the link on your site proper, it won't index it from the sitemap anyway. We've seen this proven time and time again with Stack Overflow questions. Am I wrong? Do sitemaps make sense, and we're somehow just using them incorrectly?

  • Unity: Is there a way to edit a Skin file?

    - by Roberto
    My project has multiple skins and sometimes we have to deal with skins with many custom styles. Editing them in the editor is difficult, for instance, I cannot delete one style that is not the last one without deleting the ones after it. Would there be a way to edit a file that represents this skin? Could I edit a skin file if I use Text in the Asset Serialization Mode (Unity Pro)? If not, is there something in the Unity Store to help me better edit skins?

  • Is Google Analytics Part Of Google's Search Engine Algorithm

    - by ub3rst4r
    I was wondering if anyone knows if Google uses the data it receives from Google Analytics to help determine a websites SERP (Search Engine Rank Position). For example, if my website is getting 1000 users visiting my website from Canada and only 100 users visiting my website from the USA, does that mean my website will be ranked higher on Google.ca and lower on Google.com? And, if a website is using Google Analytics will it be ranked higher for the organic search engine keywords?

  • PERT shows relationships between defined tasks in a project without taking into consideration a time line

    The program evaluation and review technique (PERT) shows relationships between defined tasks in a project without taking into consideration a time line. This chart is an excellent way to identify dependencies of tasks based on other tasks. This chart allows project managers to identify the critical path of a project to minimize any time delays to the project. According to Craig Borysowich in his article “Pros & Cons of the PERT/CPM Method stated the following advantages and disadvantages: “PERT/CPM has the following advantages: A PERT/CPM chart explicitly defines and makes visible dependencies (precedence relationships) between the WBS elements, PERT/CPM facilitates identification of the critical path and makes this visible, PERT/CPM facilitates identification of early start, late start, and slack for each activity, PERT/CPM provides for potentially reduced project duration due to better understanding of dependencies leading to improved overlapping of activities and tasks where feasible.  PERT/CPM has the following disadvantages: There can be potentially hundreds or thousands of activities and individual dependency relationships, The network charts tend to be large and unwieldy requiring several pages to print and requiring special size paper, The lack of a timeframe on most PERT/CPM charts makes it harder to show status although colors can help (e.g., specific color for completed nodes), When the PERT/CPM charts become unwieldy, they are no longer used to manage the project.” (Borysowich, 2008) Traditionally PERT charts are used in the initial planning of a project like in a project that is utilizing the waterfall approach. Once the chart was created then project managers could further analyze this data to determine the earliest start time for each stage in the project. This is important because this information can be used to help forecast resource needs during a project and where in the project. However, the agile environment can approach this differently because of their constant need to be in contact with the client and the other stakeholders.  The PERT chart can also be used during project iteration to determine what is to be worked on next, such as a prioritized To-Do list a wife would give her husband at the start of a weekend. In my personal opinion, the COTS-centric environment would not really change how a company uses a PERT chart in their day to day work. The only thing I can is that there would be less tasks to include in the chart because the functionally milestones are already completed when the components are purchased.

Oct 18 02:15:06.937 [Notice] We were compiled with headers from version 2.0.19-stable of Libevent, but we're using a Libevent library that says it's version 2.0.21-stable.

Oct 18 02:15:06.938 [Notice] Opening Socks listener on 127.0.0.1:9050 Oct 18 02:15:06.938 [Warning] Could not bind to 127.0.0.1:9050: Address already in use. Is Tor already running? Oct 18 02:15:06.938 [Warning] /var/run/tor is not owned by this user (waqas, 1000) but by debian-tor (118). Perhaps you are running Tor as the wrong user? Oct 18 02:15:06.938 [Warning] Before Tor can create a control socket in "/var/run/tor/control", the directory "/var/run/tor" needs to exist, and to be accessible only by the user account that is running Tor. (On some Unix systems, anybody who can list a socket can connect to it, so Tor is being careful.) Oct 18 02:15:06.938 [Warning] Failed to parse/validate config: Failed to bind one of the listener ports. Oct 18 02:15:06.938 [Error] Reading config failed--see warnings above. Please Help !
