  • Indian government department have more unsecure website then others.

    - by Anirudha
    Originally posted on: http://geekswithblogs.net/anirugu/archive/2013/10/26/indian-government-department-have-more-unsecure-website-then-others.aspxOne of my friend share his college experience with me. He is not related with computer science. One day he told me that Ankia Fadia come to their college. In front of many student he show how to hack BSNL website by tricks. he break the flow how BSNL site work. I have told them BSNL is one of the most unsecure website of India   If you logged-in to website maybe it’s run in few seconds but sometime it run in 58 minute. OK this is not grammar mistake 58 minute is less then 1 hour. This means open a tab and put the link to open. it will open in hours. If you are using IE8, Chrome and Firefox you will be forced to use IE7 or downgrade. I simply use Ie7 mode in IE for make it work. This happen because they use something that is called DynaTrace. This site is most unsecure. now guess how !   Suppose my username is xyz and password is abc. How I can reset the password I simply go to website and in their site when I do reset my password he told me to fill password and password will not worked here.you can use here password here to reset my password. Remember that username are different then broadband username and password. Suppose if I want to reset your password I simply need to know your broadband username and I can reset it myself. I just logged in with my username and when I open the page for reset password I can fill your bb username and password will work here. I have not tried this. the broadband username can easily guess. this is depend on same way how people’s broandband username made. IS this Safe ? Nope, There are many thing on the site which make me feel that is 1900 century website. They still lived in popup life.  These site are nothing but a crap. not work most of time and when work it’s run too slowly.

  • MAXDOP in SQL Azure

    - by Herve Roggero
    In my search of better understanding the scalability options of SQL Azure I stumbled on an interesting aspect: Query Hints in SQL Azure. More specifically, the MAXDOP hint. A few years ago I did a lot of analysis on this query hint (see article on SQL Server Central:  http://www.sqlservercentral.com/articles/Configuring/managingmaxdegreeofparallelism/1029/).  Here is a quick synopsis of MAXDOP: It is a query hint you use when issuing a SQL statement that provides you control with how many processors SQL Server will use to execute the query. For complex queries with lots of I/O requirements, more CPUs can mean faster parallel searches. However the impact can be drastic on other running threads/processes. If your query takes all available processors at 100% for 5 minutes... guess what... nothing else works. The bottom line is that more is not always better. The use of MAXDOP is more art than science... and a whole lot of testing; it depends on two things: the underlying hardware architecture and the application design. So there isn't a magic number that will work for everyone... except 1... :) Let me explain. The rules of engagements are different. SQL Azure is about sharing. Yep... you are forced to nice with your neighbors.  To achieve this goal SQL Azure sets the MAXDOP to 1 by default, and ignores the use of the MAXDOP hint altogether. That means that all you queries will use one and only one processor.  It really isn't such a bad thing however. Keep in mind that in some of the largest SQL Server implementations MAXDOP is usually also set to 1. It is a well known configuration setting for large scale implementations. The reason is precisely to prevent rogue statements (like a SELECT * FROM HISTORY) from bringing down your systems (like a report that should have been running on a different in the first place) and to avoid the overhead generated by executing too many parallel queries that could cause internal memory management nightmares to the host Operating System. Is summary, forcing the MAXDOP to 1 in SQL Azure makes sense; it ensures that your database will continue to function normally even if one of the other tenants on the same server is running massive queries that would otherwise bring you down. Last but not least, keep in mind as well that when you test your database code for performance on-premise, make sure to set the DOP to 1 on your SQL Server databases to simulate SQL Azure conditions.

  • Big Data – Interacting with Hadoop – What is PIG? – What is PIG Latin? – Day 16 of 21

    - by Pinal Dave
    In yesterday’s blog post we learned the importance of the HIVE in Big Data Story. In this article we will understand what is PIG and PIG Latin in Big Data Story. Yahoo started working on Pig for their application deployment on Hadoop. The goal of Yahoo to manage their unstructured data. What is Pig and What is Pig Latin? Pig is a high level platform for creating MapReduce programs used with Hadoop and the language we use for this platform is called PIG Latin. The pig was designed to make Hadoop more user-friendly and approachable by power-users and nondevelopers. PIG is an interactive execution environment supporting Pig Latin language. The language Pig Latin has supported loading and processing of input data with series of transforming to produce desired results. PIG has two different execution environments 1) Local Mode – In this case all the scripts run on a single machine. 2) Hadoop – In this case all the scripts run on Hadoop Cluster. Pig Latin vs SQL Pig essentially creates set of map and reduce jobs under the hoods. Due to same users does not have to now write, compile and build solution for Big Data. The pig is very similar to SQL in many ways. The Ping Latin language provide an abstraction layer over the data. It focuses on the data and not the structure under the hood. Pig Latin is a very powerful language and it can do various operations like loading and storing data, streaming data, filtering data as well various data operations related to strings. The major difference between SQL and Pig Latin is that PIG is procedural and SQL is declarative. In simpler words, Pig Latin is very similar to SQ Lexecution plan and that makes it much easier for programmers to build various processes. Whereas SQL handles trees naturally, Pig Latin follows directed acyclic graph (DAG). DAGs is used to model several different kinds of structures in mathematics and computer science. DAG Tomorrow In tomorrow’s blog post we will discuss about very important components of the Big Data Ecosystem – Zookeeper.

  • ODUG lands DotNetNuke guru Nik Kalyani as a speaker

    - by Brian Scarbeau
    If you are in the Orlando, FL area during the first week of May then you should head over to the Orlando DotNetNuke user group meeting. Nik Kalyani will be the speaker and you will learn a great deal from him. DotNetNuke Module Development with the MVP Pattern This session focuses on introducing attendees to the Model-View-Presenter pattern, support for which was recently introduced in the DotNetNuke Core. We'll start with a quick overview of the pattern, compare it to MVC, and then dive right into code. We will start with fundamentals and then develop a full-featured module using this pattern. In order to do justice to the pattern, we will use ASP.NET WebForms controls minimally and implement most of the UI using jQuery plug-ins. Finally, to increase audience participation (both present at the meeting and remote), we will use a hackathon-style model and allow anybody, anywhere to follow along with the presentation and code their own MVP-based solution that they can share online during or after the session. A URL with full instructions for the hackathon will be posted online a few days prior to the meeting. About Our Speaker Nik Kalyani is Co-founder and Strategic Advisor for DotNetNuke Corp., the company that manages the DotNetNuke Open Source project. Kalyani is also Founder and CEO of HyperCrunch. He is a technology entrepreneur with over 18 years of experience in the software industry. He is irrationally exuberant about technology, especially if it has anything to do with the Internet. HyperCrunch is his latest startup business that builds on his knowledge and experience from prior startups, two of them venture-funded. Kalyani is a creative tinkerer perpetually interested in looking around the corner and figuring out new and interesting ways to make the world a better place. An experienced web developer, he finds the business strategy and marketing aspects of the software business more exciting than writing code. When he does create software, his primary expertise is in creating products with compelling user experiences. Kalyani is most proficient with Microsoft technologies, but has no religious fanaticism about them. Kalyani has a bachelor’s degree in computer science from Western Michigan University. He is a frequent speaker at technology conferences and user group meetings. He lives in Mountain View, California with his wife and daughters. He blogs at http://www.kalyani.com and is @techbubble on Twitter.

  • News, Perspektiven und jede Menge Gesprächsstoff - Der Oracle Partner Day 2012

    - by A&C Redaktion
    Was für ein Tag! Unter dem Motto „Maximize your Potential“ kamen über 470 Teilnehmerinnen und Teilnehmer beim Oracle Partner Day 2012 zusammen. Hier drehte sich alles um unsere Partner, die, wie Silvia Kaske, Senior Director Alliances & Channel Europe North, in ihrer Begrüßung betonte, „ein sehr wichtiger Baustein in der Wachstumsstrategie von Oracle“ sind. Wie einmalig diese Partnerschaft ist, betonte auch David Callaghan, Senior Vice President EMEA Alliances & Channel in seiner Keynote. Niemand sonst habe, so Callaghan, in ähnlichem Ausmaß wie Oracle, Hardware und Software tatsächlich integriert. So manche Anbieter würden zwar beides zusammenschnüren, aber bei weitem nicht so optimal abgestimmt und verflochten, wie beim „Red Stack“ von Oracle. Neben Keynotes von Jürgen Kunz, SVP Technology Northern Europe & Country Leader Germany, und Christian Werner, Senior Director Alliances & Channels Germany, zu Neuheiten und Entwicklungspotenzialen im Oracle Universum und den Präsentationen aus verschiedenen Spezialisierung-Fachgebieten, gab es sogar einen Blick in die Zukunft der IT: Der Informatiker Professor Hermann Maurer präsentierte nicht nur existierende und geplante Innovationen, etwa die berüchtigte Computerbrille, die bald das Smartphone abzulösen soll – eine ordentliche Portion Science-Fiction war auch dabei. Im Laufe des Tages nutzten diverse Partner die Möglichkeit, vor Ort den Test als OPN Implementation Specialist beim Testcenter Pearson Vue abzulegen. Viele Teilnehmer zeigten sich beeindruckt von den vielen guten Gesprächen untereinander und schöpften die Möglichkeit zum Networking und Erfahrungsaustausch voll aus. Bei einem so dichten Programm ist es natürlich schwierig, wirklich alles mitzunehmen. Daher haben wir die Präsentationen, die auf dem Oracle Partner Day gehalten wurden, hier in der Agenda noch einmal für Sie zusammengestellt. Spannend wurde es bei der Oracle Partner Award Ceremony: Zum zweiten Mal wurden dort deutsche Partner ausgezeichnet, die sich mit besonderem Engagement und Erfolg spezialisiert haben. Wer die glücklichen Gewinner sind und was ihr Unternehmen auszeichnet, lesen sie ebenfalls hier im Blog. Allen Siegern gratulieren wir noch einmal ganz herzlich! Nachdem es im voraus schon wilde Spekulationen gab, was sich wohl hinter der „Oracle Sports Challenge“ verbergen würde, wollen wir diese Frage auch hier auflösen: Wer nach dem vielen Sitzen Lust auf Bewegung hatte, konnte sich verschiedenen, mehr oder weniger sportlichen Herausforderungen stellen. Zu meistern waren verschiedene Geschicklichkeits-Spiele, unter anderem ein fast mannshoher „Oracle Stack“, den es in Yenga-Manier aufrecht zu erhalten galt, Torschüsse auf ein Tor, das von einem vollautomatischen Robo-Keeper bewacht wurde und eine Video-Wand mit einem spielerischen Reaktionstest rund um den „Red Stack“. Den ganzen Tag über konnten die Teilnehmer hinter QR-Codes versteckte Buchstaben sammeln und mit etwas Glück und Geschick einen von drei iPod Supernanos gewinnen. Abgerundet wurde das Programm durch Auftritte der Entertainment-Saxophonistinnen „Hot Sax Club“, der beeindruckenden Fußball-Freestyler mit ihrer Ballakrobatik, dem Close-up Magier Marc Gassert und unseren DJ, der für Stimmung sorgte. Eindrücke und Highlights vom Oracle Partner Day in Frankfurt sehen Sie hier, im Best-of-Video und in unserer Fotogalerie. Lassen Sie einen gelungenen Tag noch einmal Revue passieren – oder sehen Sie, was Sie alles verpasst haben. Aber: nicht traurig sein, der nächste Oracle Partner Day kommt bestimmt!

  • Too Few Women in IT!

    - by Yolande
    Last year, only 1% of attendees at Devoxx were women . This year, Devoxx addressed the issue in a panel entitled "Why We Should Target Women." On the panel were Kim Ross, Régina ten Bruggencate, Trisha Gee, Antonio Goncalves and Claude Falguiére. The moderator was Martijn Verburg. The discussion focused on how to attract women to programming and how to get current women programmers to be more active in the community. The panelists agreed that the IT field should not just attract more women but also men of different ethnic backgrounds. The lack of women in programming is in part a cultural issue that differs from region to region. In developed countries, very few women work as programmers whereas in Brazil and India a lot of women pursue careers in IT.  Women in developed countries perceive the field as isolating and very few young women graduate in computer science.  This perception of isolation was based in reality decades ago, but that is no longer the case today. Main ideas discussed by the panel: - Parents should encourage their daughters to play with Lego and learn programming - More organizations should target girls in high schools and young women in university to expose them to programming.  Duchess organization is planning on being more involved with young girl events and mentoring. - Women tend to be more self-critical about their skills and are intimidated by high skill requirements in job advertisements. Companies should change job advertisements to get more women to interviews. - Panelists don't recommend affirmative action because women feel favored and lose credibility. They want to be judged for their skills. - Panelists recommend acting the same way when dealing with either female or male co-workers and managers - Women need mentors (men or women) to learn to become speakers at conferences and to promote themselves better - Men should be sensitive to the fact that women are alone at work to respond to men teasing. The balance of power at work is different from a social setting. - Men also experience discrimination on the job. It is more difficult for men to take time off when their children are sick, for example. Equal valuing of parental obligations could result in equal pay for women.

Is there any other way of doing this? I'm thinking of the following, but the current setup is really the most convenient one since I also have to use the data on the client side: store the product details in a file. So something like ASIN123.json store the product details in one big file. (I'm guessing it will be a drag to extract data from this file) store each of the fields in the details in its own table field Thanks in advance!

  • SQL Contests – Solution – Identify the Database Celebrity

    - by Pinal Dave
    Last week we were running contest Identify the Database Celebrity and we had received a fantastic response to the contest. Thank you to the kind folks at NuoDB as they had offered two USD 100 Amazon Gift Cards to the winners of the contest. We had also additional contest that users have to download and install NuoDB and identified the sample database. You can read about the contest over here. Here is the answer to the questions which we had asked earlier in the contest. Part 1: Identify Database Celebrity Personality 1 – Edgar Frank “Ted” Codd (August 19, 1923 – April 18, 2003) was an English computer scientist who, while working for IBM, invented the relational model for database management, the theoretical basis for relational databases. He made other valuable contributions to computer science, but the relational model, a very influential general theory of data management, remains his most mentioned achievement. (Wki) Personality 2 – James Nicholas “Jim” Gray (born January 12, 1944; lost at sea January 28, 2007; declared deceased May 16, 2012) was an American computer scientist who received the Turing Award in 1998 “for seminal contributions to database and transaction processing research and technical leadership in system implementation.” (Wiki) Personality 3 – Jim Starkey (born January 6, 1949 in Illinois) is a database architect responsible for developing InterBase, the first relational database to support multi-versioning, the blob column type, type event alerts, arrays and triggers. Starkey is the founder of several companies, including the web application development and database tool company Netfrastructure and NuoDB. (Wiki) Part 2: Identify NuoDB Samples Database Names In this part of the contest one has to Download NuoDB and install the sample database Hockey. Hockey is sample database and contains few tables. Users have to install sample database and inform the name of the sample databases. Here is the valid answer. HOCKEY PLAYERS SCORING TEAM Once again, it was indeed fun to run this contest. I have received great feedback about it and lots of people wants me to run similar contest in future. I promise to run similar interesting contests in the near future. Winners Within next two days, we will let winners send emails. Winners will have to confirm their email address and NuoDB team will send them directly Amazon Cards. Once again it was indeed fun to run this contest. Reference: Pinal Dave (http://blog.SQLAuthority.com) Filed under: PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, T SQL

  • Visual Studio 2010 plus Help Index : have your cake and eat it too

    - by Adrian Hara
    Although the team's intentions might have been good, the new help system in Visual Studio 2010  is a huge step backwards (more like a cannonball-shot-kind-of-leap really) from the one we all know (and love?) in Visual Studio 2008 and 2005 (and heck, even VS6). Its biggest problem, from my point of view, is the total and complete lack of the Help Index feature: you know...the thing where you just go and type in what you're looking for and it filters down the list of results automatically. For me this was the number one productivity feature in the "old" help system, allowing me to find stuff very quickly. Number two is that it's entirely web based and runs, by default, in the browser. So imagine, when you press F1, a new tab opens in your default browser pointing to the help entry. While this is wrong in many ways, it's also extremely annoying, cleaning up tabs in the browser becomes a chore which represents a serious productivity hit. These and many other problems were discussed extensively (and rather vocally) on connect but it seems MS seemed to ignore it and opt to release the new help system anyway, with the promise that more features will be added in a later release. Again, it kind of amazes me that they chose to ship a product with LESS features that the previous one and, what's worse, missing KEY features, just so it's "standards based" and "extensible". To be honest, I couldn't care less about the help system's implementation, I just want it to be usable and I would've thought that by now the software community and especially MS would've learned this lesson. In the end, what kind of saddens me is that MS regards these basic features as ones for the "power help user". I mean, come on! I mean a) it's not like my aunt's using Visual Studio 2010 and she represents the regular user, b) all software developers are, by definition, power users and c) it's a freakin help, not rocket science! As you can tell, I'm pretty pissed. Even more so because I really feel that the VS2010 & co. release really is a great one, with a lot of effort going into the various platforms and frameworks, most (if not all) of them being really REALLY good products. And then they go and screw up the help! How lame is that?!   Anyway, it's not all gloom-and-doom. Luckily there is a desktop app which presents a UI over the new help system that's very close to what was there in VS2008, by Robert Chandler (to which I hereby declare eternal gratitude). It still has some minor issues but I'll take it over the browser version of the help any day. It's free, pretty quick (on my machine ;)) and nicely usable. So, if you hate the new help system (passionately) like I do, download H3Viewer now.

  • Economic modelling - Resources for valuing goods

    - by Rushyo
    tl;dr: What economic/computer science books would you suggest for learning about economic valuation of goods and simulations thereof? I'm looking to create an economic model for a game based on goods created procedurally. Every natural resource and produced good would be procedurally generated, with certain goods being assigned certain uses. Fakesium might be used for the production of Weapon A and produced from Fakesium factories which use Dilithium and Widgets as reagents, where Widgets are also the product of Foo and Bar The problem is not creating the resources and their various production utlities - but getting the game's AI empires and merchants to correctly value the goods according to their scarcity, utility and production costs. I need to create a simulation of goods which allows the various game factions to assign a common value denominator (credits) to each resource, depending on how much its worth to that empire. I see the simulation being something like: "I have a high requirement for Weapon A. Since I don't have much of Fakesium, which is needed for Weapon A - I must have a high demand for Fakesium. If I can acquire Fakesium, devalue it. If not, increase its value - and also increase demand for Dilithium and Widgets too." This is very naive - because it may be much much cheaper for the empire to simply purchase Dilithium and Widgets directly rather than purchasing Fakesium, for example. Another example is two resources might allow the creation of Weapon A (Fakesium and Lieron), so we'd need to consider that. I've been scratching my head over the problem and it keeps growing. By the time the player joins the world, I'd expect enough iterations of this process to have occurred that prices would have largely normalised - and would then only trigger rarely to compensate for major changes (eg. if the player blows up the world's only Foo mine!) Could anyone suggest resources (books, largely) which outline this style of modelling, preferably in the context of simulations? Since this problem would never occur outside fantasy worlds, I figured this is probably the most likely place to find people who have encountered similar problems and I'm sure there's people who know of good places for Games Developers to start looking at less specific economic theory too. Additionally, does anyone know of any developers with blogs whose games or research applications perform similar modelling?

  • Game timings and formats

    - by topright
    There are more or less standardized TV-show/movie formats and recommended timings: 1. By the early 1960s, television companies commonly presented half-hour long "comedy" series, or one hour long "dramas." Half-hour series were mostly restricted to situation comedy or family comedy, and were usually aired with either a live or artificial laugh track. One hour dramas included genre series such as police and detective series, westerns, science fiction, and, later, serialized prime time soap operas. Programs today still overwhelmingly conform to these half-hour and one hour guidelines. Source 2. In the United States, most medical dramas are one hour long. Source 3. Traditionally serials were broadcast as fifteen minute installments each weekday in daytime slots. In 1956 As the World Turns debuted as the first half-hour soap opera. All soap operas broadcast half-hour episodes by the end of the 1960s. With increased popularity in the 1970s most soap operas expanded to an hour (Another World even expanded to ninety minutes for a short time). More than half of the serials had expanded to one hour episodes by 1980. As of 2010, six of the seven US serials air one hour episodes each weekday. Source Interesting. Are there any standards of timing in game development? Well, 5-20 minutes casual games, of course. There is even a "5-minutes-game" site. And 1-hour-gamer site. Are there 1-week, 1-year, 1-eternity game formats? Chess and Go - deep games that you can study all your life; but they are played in hour or several days (pro games). Addictive long-term online role-playing games (without win-condition) are played in monthes and, possibly, years. Replayability is an important factor to consider. It's good when game design document contains a line: "A game is designed for solving in X hours". How can it be measured before there is any prototype or demo? When you know your game format, you know your audience (and vice versa). It is practical question. Are there psychological researches about dynamic of gaming interest and involvement? And is there a correlation between game format and game genre?

  • Programming Windows 8 Apps with HTML, CSS, and JavaScript - All you need in one title

    It took me a while to work through the 800+ pages of this title. And yes, I really mean working not reading... Since the release of Windows 8 it should be obvious to any Windows software developer that there are new ways to develop, deploy and market applications for a broader audience. Interestingly, Microsoft started to narrow the technological gap between the various platforms - desktop, web, smartphone and XBox - and development of modern apps with HTML, CSS and JavaScript couldn't be easier. Kraig covers all facets of modern Windows 8 apps from the basic building blocks and project templates in Visual Studio 2012 over to the thoughtful use of specific APIs to finally proper deployment in the App Store and potential monetization. The organisation of the book is lied out like step by step instructions or a tutorial. Kraig literally takes the reader by the hand and explains in detail in his examples about the reasons, the pros, and the cons of a certain way of implementation. Thanks to cross-references to other chapters he leaves the choice to the reader to dig deeper right now or to catch up at some time later. Personally, I have to admit that I really enjoyed the relaxed writing style. App development is not dust-dry rocket science and it should be joyful to learn about new technologies. And thanks to the richness of the various chapters and samples you could easily adapt and transfer the knowledge gained in this title to other platforms like Windows Phone 8. And last but not least: The ebook is freely available at Amazon, Microsoft Press and O'Reilly. Don't think about it, just get the book. Now. Update: I already mentioned this title in other blog entries which are related to Microsoft certification. Feel free to read on and to discover more online resources: Learning content for MCSDs: Web Applications and Windows Store Apps using HTML5 More content for MCSDs: Web Applications and Windows Store Apps using HTML5 O'Reilly offers free webcasts on their site, too. And in case that you would like to know more about Kraig's book and his experience with various development teams, please checkout this one: Zero to App in Two Weeks: Programming Windows 8 Apps in HTML, CSS, and JavaScript. The recording should be available soon.

  • Teacher demands excessive/unjustified use of Design Patterns

    - by SoboLAN
    I study computer science and I have a class called "Programming Techniques". Its purpose is to teach (us) good object oriented design principles. During the semester we have homeworks, programs that we must write to demonstrate what we've learned. The lab assistant demands for each of these homeworks that specific design patterns should be used. For example, the current homework is an application used for processing customer orders. We are demanded to use either "Factory Method" or "Abstract Factory" design patterns for this. It gets even worse: at the end of the semester we must write a program (something more complex) that must use at least one creational pattern, at least one structural pattern and at least one behavioural pattern. Is it normal to demand this ? I mean, forcing us to design our programs in such a way that a specific design pattern makes sense is just beyond what I consider ok. If I'm a car mechanic and have a huge tool box, then I will use a certain tool from that box if and when the situation demands it. Not more, not less. If my design of the application doesn't demand at all the use of "Abstract Factory" (for example), then why should I implement it ? I'm not sure yet if the senior lecturer agrees with what the lab assistant is demanding, but I want to talk to him about it and I need solid arguments to do so. How should I approach this problem with him ? PS: I'm sure there must be a better way to teach us these things. Maybe making us each week read about 3 design patterns and the next week giving us a test with small but specific programming or architectural situations/problems. The goal in that test would be to identify what design patterns would make sense and how they could be implemented. This way, he can see if we understand them. EDIT: These homeworks are not just 100-line programs, they have quite a lot of requirements and are fairly complicated. This is the reason we have about 2 - 3 weeks of deadline for each of them. I agree that practicing this is the best way to learn. But shouldn't smaller programs/applications be used for this ? Something just for demonstrating purposes. Not big programs with lots of requirements/classes/etc.

  • It's called College.

    - by jeffreyabecker
    Today I saw yet another 'GUID vs int as your primary key' article. Like most of the ones I've read this was filled with technical misrepresentations and out-right fallices. Chef's famous line that "There's a time and a place for everything children" applies here. GUIDs have distinct advantages and disadvantages which should be considered when choosing a data type for the primary key. Fallacy 1: "Its easier" An integer data type(tinyint, smallint, int, bigint) is a better artifical key than a GUID because its easier to remember. I'm a firm believer that your artifical primary keys should be opaque gibberish. PK's are an implementation detail which should never be exposed to the user or relied on for business logic. If you want things to come back in an order, add and ORDER BY clause and SortOrder fields. If you want a human-usable look-up add a business key with a unique constraint. If you want to know what order things were inserted into a table add a timestamp. Fallacy 2: "Size Matters" For many applications, the size of the artifical primary key is going to be irrelevant. The particular article which kicked this post off stated repeatedly that joining against an int has better performance than joining against a GUID. In computer science the performance of your algorithm is always a function of the number of data points. This still holds true for databases. Unless your table is very large, the performance difference between an int and a guid probably isnt going to be mesurable let alone noticeable. My personal experience is that the performance becomes an issue when you start having billions of rows in the table. At this point, you should probably start looking to move from int to bigint so the effective space/performance gain isnt as much as you'd think. GUID Advantages: Insert-ability / Mergeability: You can reliably insert guids into tables without key collisions. Database Independence: Saving entities to the database often requires knowing ids. With identity based ids the id must be selected back after every insert. GUIDs can be generated application-side allowing much faster inserts. GUID Disadvantages: Generatability: You can calculate the next id for an integer pk pretty easily in your head but will need a program to generate GUIDs. Solution: "Select top 100 newid() from sysobjects" Fragmentation: most GUID generation algorithms generate pseudo random GUIDs. This can cause inserts into the middle of your clustered index. Solutions: add a default of newsequentialid() or use GuidComb in NHibernate.

  • SQLAuthority News – Presenting at Great Indian Developer Summit 2012 – SQL Server Misconception and Resolutions

    - by pinaldave
    Earlier during TechEd 2012, I presented a session on SQL Server Misconception and Resolutions. It was a pleasure to present this session with Vinod Kumar during the event. Great Indian Developer Summit is around the corner and I will be presenting there once again with the same topic. We had an excellent response during the last event; the hall was so filled, but there were plenty who were not able to get into the session as there was no place for them to sit or stand inside. Well, here is another chance for all who missed the presentation. New Additions During the last session, we were a two-presenter tag team, and we presented the session in a sense that it would suit two speakers in one stage. But this time, I am the only presenter, so I decided to present this session in a much different way. I will still assume there are two presenters. One of the presenters will be me, of course, and the second person will be YOU! Yes, you read that right – you will be presenting this session with me. If you wonder how, well, you will have to attend the session to figure it out. Talking Points We will be talking about the following topics in the session which we will relate to SQL Server: Moon Landing Napoléon Bonaparte Wall of China Bollywood …and of course, SQL Server itself. I promise that this 45 minute- presentation will be the one of the highlights of the event for you. Goodies I can only promise 20 goodies as of the moment. I might bring more when you meet me there. Session Details Title: SQL Server Misconceptions and Resolution – A Practical Perspective (Add to Calendar) Abstract: “The earth is flat”! – An ancient common misconception, which has been proven incorrect as we progressed in modern times. In this session, we will see various database misconceptions prevailing and their resolutions with the aid of the demos. In this unique session, the audience will be a part of the conversation and resolution. Date and Time: April 17, 2012, 16:55 to 17:40 Location: J. N. Tata Auditorium, National Science Symposium Complex (NSSC), Bangalore, India Add to Calendar Reference : Pinal Dave (http://blog.sqlauthority.com) Filed under: PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, SQLAuthority Author Visit, SQLAuthority News, T SQL, Technology

  • How does I/O work for large graph databases?

    - by tjb1982
    I should preface this by saying that I'm mostly a front end web developer, trained as a musician, but over the past few years I've been getting more and more into computer science. So one idea I have as a fun toy project to learn about data structures and C programming was to design and implement my own very simple database that would manage an adjacency list of posts. I don't want SQL (maybe I'll do my own query language? I'm just having fun). It should support ACID. It should be capable of storing 1TB let's say. So with that, I was trying to think of how a database even stores data, without regard to data structures necessarily. I'm working on linux, and I've read that in that world "everything is a file," including hardware (like /dev/*), so I think that that obviously has to apply to a database, too, and it clearly does--whether it's MySQL or PostgreSQL or Neo4j, the database itself is a collection of files you can see in the filesystem. That said, there would come a point in scale where loading the entire database into primary memory just wouldn't work, so it doesn't make sense to design it with that mindset (I assume). However, reading from secondary memory would be much slower and regardless some portion of the database has to be in primary memory in order for you to be able to do anything with it. I read this post: Why use a database instead of just saving your data to disk? And I found it difficult to understand how other databases, like SQLite or Neo4j, read and write from secondary memory and are still very fast (faster, it would seem, than simply writing files to the filesystem as the above question suggests). It seems the key is indexing. But even indexes need to be stored in secondary memory. They are inherently smaller than the database itself, but indexes in a very large database might be prohibitively large, too. So my question is how is I/O generally done with large databases like the one I described above that would be at least 1TB storing a big adjacency list? If indexing is more or less the answer, how exactly does indexing work--what data structures should be involved?

  • Should I be an algorithm developer, or java web frameworks type developer?

    - by Derek
    So - as I see it, there are really two kinds of developers. Those that do frameworks, web services, pretty-making front ends, etc etc. Then there are developers that write the algorithms that solve the problem. That is, unless the problem is "display this raw data in some meaningful way." In that case, the framework/web developer guy might be doing both jobs. So my basic problem is this. I have been an algorithms kind of software developer for a few years now. I double majored in Math and Computer science, and I have a master's in systems engineering. I have never done any web-dev work, with the exception of a couple minor jobs, and some hobby level stuff. I have been job interviewing lately, and this is what happens: Job is listed as "programmer- 5 years of experience with the following: C/C++, Java,Perl, Ruby, ant, blah blah blah" Recruiter calls me, says they want me to come in for interview In the interview, find out they have some webservices development, blah blah blah When asked in the interview, talk about my experience doing algorithms, optimization, blah blah..but very willing to learn new languages, frameworks, etc Get a call back saying "we didn't think you were a fit for the job you interviewed wtih, but our algorithm team got wind of you and wants to bring you on" This has happened to me a couple times now - see a vague-ish job description looking for a "programmer" Go in, find out they are doing some sort of web-based tool, maybe with some hardcore algorithms running in the background. interview with people for the web-based tool, but get an offer from the algorithms people. So the question is - which job is the better job? I basically just want to get a wide berth of experience at this level of my career, but are algorithm developers so much in demand? Even more so than all these supposed hot in demand web developer guys? Will I be ok in the long run if I go into the niche of math based algorithm development, and just little to no, or hobby level web-dev experience? I basically just don't want to pigeon hole myself this early. My salary is already starting to get pretty high - and I can see a company later on saying "we really need a web developer, but we'll hire this 50k/year college guy, instead of this 100k/year experience algorithm guy" Cliffs notes: I have been doing algorithm development. I consider myself to be a "good programmer." I would have no problem picking up web technologies and those sorts of frameworks. During job interviews, I keep getting "we think you've got a good skillset - talk to our algorithm team" instead of wanting me to learn new skills on the job to do their web services or whhatever other new technology they are doing. Edit: Whenever I am talking about algorithm development here - I am talking about the code that produces the answer. Typically I think of more math-based algorithms: solving a financial problem, solving a finite element method, image processing, etc

  • After 10 Years, MySQL Still the Right Choice for ScienceLogic's "Best Network Monitoring System on the Planet"

    - by Rebecca Hansen
    ScienceLogic has a pretty fantastic network monitoring appliance.  So good in fact that InfoWorld gave it their "2013 Best Network Monitoring System on the Planet" award.  Inside their "ultraflexible, ultrascalable, carrier-grade" enterprise appliance, ScienceLogic relies on MySQL and has since their start in 2003.  Check out some of the things they've been able to do with MySQL and their reasons for continuing to use MySQL in these highlights from our new MySQL ScienceLogic case study. Science Logic's larger customers use their appliance to monitor and manage  20,000+ devices, each of which generates a steady stream of data and a workload that is 85% write. On a large system, the MySQL database: Averages 8,000 queries every second or about 1 billion queries a day Can reach 175,000 tables and up to 20 million rows in a single table Is 2 terabytes on average and up to 6 terabytes "We told our customers they could add more and more devices. With MySQL, we haven't had any problems. When our customers have problems, we get calls. Not getting calls is a huge benefit." Matt Luebke, ScienceLogic Chief Software Architect.? ScienceLogic was approached by a number of Big Data / NoSQL vendors, but decided against using a NoSQL-only solution. Said Matt, "There are times when you really need SQL. NoSQL can't show me the top 10 users of CPU, or show me the bottom ten consumer of hard disk. That's why we weren't interested in changing and why we are very interested in MySQL 5.6. It's great that it can do relational and key-value using memcached." The ScienceLogic team is very cautious about putting only very stable technology into their product, and according to Matt, MySQL has been very stable: "We've been using MySQL for 10 years and we have never had any reliability problems. Ever." ScienceLogic now uses SSDs for their write-intensive appliance and that change alone has helped them achieve a 5x performance increase.

    You may be tempted by IaaS, but you should PaaS on that or your database cloud journey will be a short one "The better option [to IaaS] is to rationalize the deployment stack so that VMs are needed only for exceptional cases," says B. R. Clouse. "By settling on a standard operating system and patch level, you create an infrastructure that potentially all of your databases can share. Now, the building block will be database instances or possibly schemas within databases. These components are the platforms on which you will deploy workloads, hence this is known as Platform as a Service (PaaS)." 'Shadow IT' can be the cloud's best friend | David Linthicum "I do not advocate that IT give up control and allow business units to adopt any old technology they want," says Infoworld cloud computing blogger David Linthicum.

  • How to build a 4x game?

    - by Marco
    I'm trying to study how succefully implement a 4x game. Area of interest: 1) map data: how to store stellars systems (graphs?), how to generate them and so on.. 2) multiplayer: how to organize code in a non graphical server and a client to display it 3) command system: what are patters to catch user and ai decisions and handle them, adding at first "explore" and "colonize" then "combat", "research", "spy" and so on (commands can affect ships, planets, research, etc..) 4) ai system: ai can use commands to expand, upgrade planets and ship I know is a big questions, so help is appreciated :D 1) Map data Best choice is have a graph to model a galaxy. A node is a stellar system and every system have a list of planets. Ship cannot travel outside of predefined paths, like in Ascendancy: http://www.abandonia.com/files/games/221/Ascendancy_2.png Every connection between two stellar systems have a cost, in turns. Generate a galaxy is only a matter of: - dimension: number of stellar systems, - variety: randomize number of planets and types (desertic, earth, etc..), - positions of each stellar system on game space - connections: assure that exist a path between every node, so graph is "connected" (not sure if this a matematically correct term) 2) Multiplayer Game is organized in turns: player 1, player 2, ai1, ai2. Server take care of all data and clients just diplay it and collect data change. Because is a turn game, latency is not a problem :D 3) Command system I would like to design a hierarchy of commands to take care of this aspect: abstract Genericcommand (target) ExploreCommand (Ship) extends genericcommand colonizeCommand (Ship) buildcommand(planet, object) and so on. In my head all this commands are stored in a queue for every planets, ships or reasearch center or spy, and each turn a command is sent to a server to apply command and change data state 4) ai system I don't have any idea about this. Is a big topic and what I want is a simple ai. Something like "expand and fight against everyone". I think about a behaviour tree to control ai moves, so I can develop an ai that try to build ships to expand and then colonize planets, upgrade them throught science and combat enemies. Could be done with a finite state machine too ? any ideas, resources, article are welcome!

  • viable part-time career in IT/programming?

    - by Rider
    Hi, I'd like to ask for some career advice from you people. Is there a viable job/career that can be done in programming/IT for the long term? Right now, I am thinking about website (PHP?) developer path. My background: I have a degree in computer science and have been a programmer/system analyst for almost 10 years. Lately I took a big break from programming and studied for a B.arch. degree (yes architecture), only to discover that architecture offers zero (0) jobs where I'm from, for 3 years already (and no, I am not going to move and the grass in not greener in other places). I have never been particularly interested in programming, in fact I was bored by it. But I was always quite good at both programming and system analysis, and very valued by practically all my employers. On the other hand, I have never been valued or offered a good job in any other field (although I can do many things, like design, architecture, translations, documentation, teaching, etc etc.) I guess the human component has been always more important for me in programming jobs - I value all the good people I worked with, but not projects. However, I have about zero skills or desire to be a project manager. I also have close to zero skills for selling myself. I like it best when I can do "my thing", have my niche, have an ownership of some project. Right now my career perspective is to do part time programming and to part time teach yoga. I have already started the yoga teaching part. Do you think that part time programming is viable? And what niche works best for that? I have considered web development, QA, or software development in a company like I did before. However, my fear is that when you do programming part-time, you get the most boring coding work, only to see your colleagues move to more interesting projects and up their respective career ladders. I also fear that part-timers are not especially needed either. And, since I don't share much enthusiasm at programming, I'd rather not be around young programmers boiling with geeky enthusiasm about coding, but rather QA mindset with people from different backgrounds and life paths might work better for me. Thanks for any advice, --Rider
