  • SQLAuthority News – Presented Technical Session at DevReach 2013, Sofia, Bulgaria – Oct 1, 2013

    - by Pinal Dave
    Earlier this month, I had a fantastic time presenting at DevReach 2013, in Sofia, Bulgaria on Oct 1, 2013. DevReach strives to be the premier developer conference in Central and Eastern Europe. It is organized annually in Sofia, Bulgaria. The 8th edition of the conference is moving to a new and bigger venue: Sofia Event Center. In my career, I have presented over 9 different countries (India, USA, Canada, Singapore, Hong Kong, Malaysia, Sri Lanka, Nepal, Thailand), this was the first time for me to present in Europe. DevReach was perfect places to start my journey in Europe as an evangelist. The event was one of the most organized event I have ever come across in my life. The DevRech organization team had perfected every minute detail of the event to perfection. After the event was over I had the opportunity to see Sofia for one day. I presented with one of my most favorite Database Worst Practices Session.

What did I do?” Chances are you have heard, or even uttered, this expression. This demo-oriented session will show many examples where database professionals were dumbfounded by their own mistakes, and could even bring back memories of your own early DBA days. The goal of this session is to expose the small details that can be dangerous to the production environment and SQL Server as a whole, as well as talk about worst practices and how to avoid them. Shedding light on some of these perils and the tricks to avoid them may even save your current job. Thanks to Team Telerik for making this one of the best event in my life.

  • Oct 5th DevReach in Sofia, Bulgaria

    - by Sahil Malik
    SharePoint 2010 Training: more information I will be at DevReach, my top favorite conference on Oct 5th. I have been visiting Devreach since it’s very inception. I don’t do a lot of conferences, just 3 or 4 a year. I am super duper picky about what conferences I attend. One of the key reasons I love visiting DevReach is the audience quality. The developers in Bulgaria are shockingly intelligent. I have always enjoyed the extremely intelligent questions and conversations I get to engage in at DevReach. And Sofia is an amazing city to top it all. My sessions this year are as follows, Day 2, 11:30 - 12:30 Architecture SPvNext – A Look At All the Exciting And New Features In SharePoint Day 2, 09:00 - 10:00 Architecture Read full article ....

  • Travelling MVP #4: DevReach 2012

    - by DigiMortal
    Our next stop after Varna was Sofia where DevReach happens. DevReach is one of my favorite conferences in Europe because of sensible prices and strong speakers line-up. Also they have VIP-party after conference and this is good event to meet people you don’t see every day, have some discussion with speakers and find new friends. Our trip from Varna to Sofia took about 6.5 hours on bus. As I was tired from last evening it wasn’t problem for me as I slept half the trip. After smoking pause in Velike Tarnovo I watched movies from bus TV. We had supper later in city center Happy’s – place with good meat dishes and nice service. And next day it begun…. :) DevReach 2012 DevReach is held usually in Arena Mladost. It’s near airport and Telerik office. The event is organized by local MVP Martin Kulov together with Telerik. Two days of sessions with strong speakers is good reason enough for me to go to visit some event. Some topics covered by sessions: Windows 8 development web development SharePoint Windows Azure Windows Phone architecture Visual Studio Practically everybody can find some interesting session in every time slot. As the Arena is not huge it is very easy to go from one sessions to another if selected session for time slot is not what you expected. On the second floor of Arena there are many places where you can eat. There are simple chunk-food places like Burger King and also some restaurants. If you are hungry you will find something for your taste for sure. Also you can buy beer if it is too hot outside :) Weather was very good for October – practically Estonian summer – 25C and over. Sessions I visited Here is the list of sessions I visited at DevReach 2012: DevReach 2012 Opening & Welcome Messsage with Martin Kulov and Stephen Forte Principled N-Tier Solution Design with Steve Smith Data Patterns for the Cloud with Brian Randell .NET Garbage Collection Performance Tips with Sasha Goldshtein Building Secured, Scalable, Low-latency Web Applications with the Windows Azure Platform with Ido Flatow It’s a Knockout! MVVM Style Web Applications with Charles Nurse Web Application Architecture – Lessons Learned from Adobe Brackets with Brian Rinaldi Demystifying Visual Studio 2012 Performance Tools with Martin Kulov SPvNext – A Look At All the Exciting And New Features In SharePoint with Sahil Malik Portable Libraries – Why You Should Care with Lino Tadros I missed some sessions because of some death march projects that are going and that I have to coordinate but it was not big loss as I had time to walk around in session venue neighborhood and see Sofia Business Park. Next year again! I will be there again next year and hopefully more guys from Estonia will join me. I think it’s good idea to take short vacation for DevReach time and do things like we did this time – Bucharest, Varna, Sofia. It’s only good idea to plan some more free time so we are not very much in hurry and also we have no work stuff to do on the trip. This far this trip has been one of best trips I have organized and I will go and meet all those guys in this region again! :)

  • What are the best ways to cope with «one of those days»? [closed]

    - by Júlio Santos
    I work in a fast-paced startup and am absolutely in love with what I do. Still, I wake up to a bad mood as often as the next guy. I find that forcing myself to play out my day as usual doesn't help — in fact, it only makes it worse, possibly ruining my productivity for the rest of the week. There are several ways I can cope with this, for instance: dropping the current task for the day and getting that awesome but low-priority feature in place; doing some pending research for future development (i.e. digging up ruby gems); spending the day reading and educating myself; just taking the day off. The first three items are productive in themselves, and taking the day off recharges my coding mana for the rest of the week. Being a young developer, I'm pretty sure there's a multitude of alternatives that I haven't come across yet. How can programmers cope with off days? Edit: I am looking for answers related specifically to this profession. I therefore believe that coping with off days in our field is fundamentally different that doing so in other areas. Programmers (especially in a start-up) are a unique breed in this context in the sense that they tend to have a multitude of tasks at hand on any given moment, so they can easily switch between these without wreaking too much havoc. Programmers also tend to work based on clear, concise objectives — provided they are well managed either by themselves or a third party — and hence have a great deal of flexibility when it comes to managing their time. Finally, our line of work creates the opportunity — necessity, if you will — to fit a plethora of tasks not directly related to the current one, such as research and staying on top of new releases and software updates.

  • Is Oracle WebCenter 11g a big SharePoint ?

    - by Guilherme J Santos
    Hi there. I have some experience with SharePoint. Now my company will use Oracle WebCenter to create a internal portal. Nobody of IT team have experience with Oracle WebCenter, and I think we could use SharePoint, as we did until now. So, what are the advantages to use Oracle WebCenter? Wich are your experiences with Oracle WebCenter 11g? And how much it is different from SharePoint. What can I do with Oracle WebCenter that I cannot do with Microsoft SharePoint?

  • Dell XPS L502Xnot detecting monitor-TV

    - by Guilherme Z. Santos
    I'm running Ubuntu 12.04 LTS on a Dell XPS L502X and when I connect the HDMI cable from the TV to the computer Ubuntu detects nothing at all, It works perfectly fine in Windows 7 though. I've already went to the Display control, plugged and unplugged the TV, clicked the Detect Displays button, and nothing. Do I have to activate the HDMI output or something? Because I used another computer with a VGA output and it worked perfectly.

  • Am I allowed to display a small image on top of a Google Maps Static Api map?

    - by Fábio Santos
    I am the webmaster to my company's website. I was asked to make the Google Map on this page smaller, but the interactive map doesn't work well at all at 300x200. I was asked to place a screenshot there but since that seems to be a violation of Google's terms I decided to use the Static Maps API. As you can see, on the page, I have a custom pointer icon. I don't want to lose it, so I intend to use HTML and CSS to place the pointer over the map, thus replacing the original pointer on the client side. Am I allowed to do that?

  • How does key-based caching work?

    - by Dominic Santos
    I recently read an article on the 37Signals blog and I'm left wondering how it is that they get the cache key. It's all well and good having a cache key that includes the object's timestamp (this means that when you update the object the cache will be invalidated); but how do you then use the cache key in a template without causing a DB hit for the very object that you are trying to fetch from the cache. Specifically, how does this affect One to Many relations where you are rendering a Post's Comments for example. Example in Django: {% for comment in post.comments.all %} {% cache comment.pk comment.modified %} <p>{{ post.body }}</p> {% endcache %} {% endfor %} Is caching in Rails different to just requests to memcached for example (I know that they convert your cache key to something different). Do they also cache the cache key?

  • Is it a good idea to put all assembly: WebResource in the same cs file?

    - by Guilherme J Santos
    I have a .NET library, with some WebControls. These webControls have Embed Resources. And we declare them like it, in all webcontrols for each cs file: Something like this: [assembly: WebResource("IO.Css.MyCSS.css", "text/css")] namespace MyNamespace.MyClass { [ParseChildren(true)] [PersistChildren(false)] [Designer(typeof(MyNamespace.MyClassDesigner))] public class QuickTip : Control, INamingContainer { //My code... } } Would it be a good idea to create a cs file and include all WebResource declarations there? Example a cs file with just: [assembly: WebResource("IO.Css.MyCSS.css", "text/css")] [assembly: WebResource("IO.Image.MyImage.png", "image/png")] //And many other WebResources of all WebControls of the Assembly

  • Stuck With grub rescue> console

    - by rej santos
    Here is the background of my issue: I just recently installed the latest version of Ubuntu along side with Windows 8 Enterprise. However upon checking the disk size, it seems that some of the portions of the hd memory were gone so I decided to check the disk partition and have seen that is was being used by another file system. Thinking that the Ubuntu takes it boots stuff from my drive C: , I deleted that partition and formated so I can use it to store some movies, music etc. Now, as I switch on my machine, I am stucked with: error: unknown filesystem grub rescue> I googled a lot and saw the following command which seems no to me like sudo, chainloader etc, all of these command only returns unknown command in the console. What I just wanted is to boot from my Windows 8 OS. Just to add, I can't open the BIOS menu so I could choose what media to boot. As I open my machine it automatically takes me to grub rescue console. Here are the thing I already have: Ubuntu Installation Disk Windows 8 System repair Disk I just don't know how to boot into these things. Let me know what to do.

  • Finding a mentor online [closed]

    - by Athena Santos
    Possible Duplicate: How to find programming mentor? I'm a programming intern, but I want to "transition" into a product manager role after graduation. I just know that I will never be a super A++ Rockstar programmer, but from my internship I know that I can be a great program manager..one of those presumably rare people who can code well (enough)/speak programmer-ese and management-ese. Being a girl, I am looking for both male and female mentors. Female, because they know what its like to be a minority, and male, because..well, you guys are tough, and I believe to succeed in tech, a girl's gotta know how to act like a man (when appropriate). I've found some really amazing people I'd like to ask to be my mentor (in blogs, magazines, etc), but sadly, I live far, far away from them. Will be awkward/rude if I shoot them an email about being a mentor? What is the best way to establish a relationship with people like these that I admire? Any volunteers? :) Thank you in advance, and I hope you all have a great day/night.

  • When must I turn my business idea into a formal Company? [closed]

    - by Sony Santos
    I'm a programmer, I have an idea, I know how to implement it, it will be a website, and that site will be my business. My question is very basic: where in timeline must I register my business as an official Company (ie, according Government laws)? Here there are some options to debate or to help answer me: Now - or as soon as I have the idea; When looking for investors (e.g., when a prototype or business plan is ready); When implementing the website; At site's launch; I must launch the website as a personal informal business and, when the business gets success and turns into a more solid and self-running one, only then I must formalize it; It doesn't matter; I can create the company when I want. Nobody talks about that. If I just have an idea, must I run into an office to create a Company? I don't think so. When I'll look for investors, the Company must to pre-exist? Or will the Company be formed with the investor? I'm looking for a generic, country-independent answer, but may the answer for your country can be useful to me. I'm Brazilian, and I believe that the country doesn't matter to this question. (Sorry if this is off-topic, but I coudn't find a batter stackexchange site to ask this.)

  • chat application: pubsubhub vs xmpp

    - by sofia
    I'm unsure on the best stack to build a chat application. Currently I'm thinking of two main options: facebook tornado cons: does not use the main chat protocol xmpp but pubsubhubbub pros: i really like its simplicity for development (webserver + webframework); pubsubhubbub also seems simpler as a protocol than xmpp; and i know python xmpp + bosch, punjab, ejabberd cons: don't know erlang; overall seems a bit harder to develop pros: uses xmpp protocol The chat app will need to have the following: Private messages Public rooms Private rooms Chat history for rooms (not forever, just the last n messages) html embedding url to chat room Both options seem scalable so that's not really my worry (we're thinking of running the app in amazon's ec2 as well). I know there's a project that builds a xmpp server using tornado but it's not ready for production use and our deadline isn't that big. Basically my main worry is ease of development vs somehow regretting later using pubsubhubbub to develop a chat app but I read somewhere that PubSubHubbub might eventually replace XMPP as REST replaced SOAP - so what do you think?

  • PHP Can't connect to MySQL on the production server

    - by Jairo Santos
    I'm having problems with connections with MySQL through PHP script. The MySQL user is root and I added GRANTS to root@'%' so I can connect from anywhere. Lets assume my MySQL host as "bigboy.com.br" The funny part is, from my local machine, on my test server, the script can connect to the MySQL server normally. But on the dedicated server where MySQL is running, the same PHP script gives me "Access denied for 'root'@'bigboy.com.br'" error.

  • jquery ui dialog fixed positioning

    - by sofia
    Hi, I needed the dialog to maintain its position fixed even if the page scrolled, so i used the extension at http://forum.jquery.com/topic/dialog-position-fixed-12-1-2010 but there's 2 problems with it: it flickers in IE and Firefox on page scroll (in Safari/Chrome it's fine) on closing and then reopening, it looses its stickyness and scrolls along with the page. Here's the code i'm using for creating the dialog: $('<div id="'+divpm_id+'"><div id="inner_'+divpm_id+'"></div><textarea class="msgTxt" id="txt'+divpm_id+'" rows="2"></textarea></div>') .dialog({ autoOpen: true, title: user_str, height: 200, stack: true, sticky: true //uses ui dialog extension to keep it fixed }); And here's the code i'm using for reopening it: jQuery('#'+divpm_id).parent().css('display','block'); Suggestions/solutions? Thanks

  • fetching a url using $.getJSON and parsing it correctly

    This is probably really stupid but i can't find the problem with my code. It fetches a url that returns json and the function is then supposed to return a string: function getit() { var ws_url = 'example.com/test.js'; var user = false; $.getJSON(ws_url, function(data) { alert('user '+data.user);//shows john user = data.user || false; } ); return user;//should return john but returns false } test.js will have something like this: {"id":"12","username":"ses","user":"john","error":""} or like this: {"error":"123"} I also tried if(data.user){}else{} but it didn't work either.. So what am i missing? Thanks :)

  • Slow performance over network (Ubuntu)

    - by Filipe Santos
    i did setup this NodeJs TCP Server and tested it with a message flooder. Just to see how the performance of the server is. While the message throughput is great if i run the server and the message flooder on the same computer (ubuntu), the throughput dramaticaly decreases if i start the server on computer1(ubuntu1) and the message flooder on computer2(also ubuntu). Both PC are on the same network. In fact, they are directly connected to each other. I started searching the internet for reasons and i suppose i need to tune TCP on both Ubuntu-pcs but until now i haven't been successfull at all. Has anyone experienced such problems, or could someone help me out?
