  • What is so good about Linux? [closed]

    - by Chris Bridgett
    Self-explanatory question title. I've only ever used Windows OS's (except Mac OSX at friends etc, years ago occasionally) and when diving into the world of programming, Linux is a name that is coming up every other tutorial or article. All my web hosts run Linux and a lot of programming literature covers how to go about various tasks on Linux as well as Windows, but other than the odd raving I've read years ago about Linux being less resource-intensive, I haven't really given it much thought. Any article I read about Linux and whether it should be used for... 'regular' use, it's shunned since any windows applications I'm familiar with will usually require the windows API and there's no end of 'hacking' to get various programs working on Linux. As far as I understand a GUI is optional on Linux too? This all sounds very noobish I'm sure, but we all start somewhere, so: What is Linux good for? What should Linux be used for?

  • SO-overflow induced passivity - how to cope?

    - by Ruben
    After not really working on my pet project for a while, I discovered Stackoverflow and upon perusing it more intensely I was quite amazed. I'm a bit of a perfectionist, so when I found eye-openers here highlighting many of the mistakes I made, I first wanted to fix everything. However, it's a pet project for a reason: I'm self-taught and I'm studying psychology, so programming skills can never become priority one (though it often helps, even in this field). Issues that stuck out were numerous security issues (e.g. CSRF-prevention and bcrypt eluded me) not object-oriented (at least the PHP part, the JS-part mostly is) no PHP framework used, so many of my DIY takes on commonly-tackled components (auth, ...) are either bad or inefficient really poor MySQL usage (no prepared statements, mysql extension, heard about setting proper indices two days ago) using mootools even though JQuery seems to be fashionable, so there's more probably always going to be better integration with services I'd like to use (like google visualization) So, my SO-induced frenzy turned into passivity. I can't do it all (soon) in the rather small amount of spare time I can spend on working on my project. I can leave some of the issues be in good conscience (speed stuff: an unfinished & unpublished project will never become popular, right?). No clear conscience without good security though and if I don't use a framework for auth and other complex stuff I'll regret having to do it myself. One obvious answer would probably be going open-source, but I think the project would need to become more impressive before others would commit to it. I can't afford to employ someone either. I do think the project deserves being worked on, though. How should I tackle it anyway? What's the best practice for little-practice people?

  • What is the most accurate/frequent report on browser usage on the Internet?

    - by Ryan Hayes
    I'm determining which browsers a new site should support. I'm looking for a respected and accurate (as possible) report on the browser versions that are currently in use. This report should, at minimum cover the % of people who use what browsers, and versions of that browser. Is there a widely accepted source for this kind of report? If so, are they regularly released and available for free? Bonus points for other metrics such as breaking down by OS, Flash versions, JS versions, etc.

  • How can I upload to a PPA without .changes file?

    - by espectalll123
    So, I'm developing an app for the Ubuntu Showdown, and as quickly is still very buggy (I had problems using it), I decided to do my app entirely from scratch, using Python/GTK+3. I've done my app and I've just packaged it just using only fakebuild dkpg-deb --build. The problem is that I can't create a .source file, as I don't have a changelog file and the debian folder cannot be used in debuild, as is uncorrectly organized.

  • Exposing business logic as WCF service

    - by Oren Schwartz
    I'm working on a middle-tier project which encapsulates the business logic (uses a DAL layer, and serves a web application server [ASP.net]) of a product deployed in a LAN. The BL serves as a bunch of services and data objects that are invoked upon user action. At present times, the DAL acts as a separate application whereas the BL uses it, but is consumed by the web application as a DLL. Both the DAL and the web application are deployed on different servers inside organization, and since the BL DLL is consumed by the web application, it resides in the same server. The worst thing about exposing the BL as a DLL is that we lost track with what we expose. Deployment is not such a big issue since mostly, product versions are deployed together. Would you recommend migrating from DLL to WCF service? If so, why? Do you know anyone who had a similar experience?

  • Computer Science Degrees and Real-World Experience

    - by Steven Elliott Jr
    Recently, at a family reunion-type event I was asked by a high school student how important it is to get a computer science degree in order to get a job as a programmer in lieu of actual programming experience. The kid has been working with Python and the Blender project as he's into making games and the like; it sounds like he has some decent programming chops. Now, as someone that has gone through a computer science degree my initial response to this question is to say, "You absolutely MUST get a computer science degree in order to get a job as a programmer!" However, as I thought about this I was unsure as to whether my initial reaction was due in part to my own suffering as a CS student or because I feel that this is actually the case. Now, for me, I can say that I rarely use anything that I learned in college, in terms of the extremely hard math, algorithms, etc, etc. but I did come away with a decent attitude and the willingness to work through tough problems. I just don't know what to tell this kid; I feel like I should tell him to do the CS degree but I have hired so many programmers that majored in things like English, Philosophy, and other liberal arts-type degrees, even some that never went to college. In fact my best developer, falls into this latter category. He got started writing software for his church or something and then it took off into a passion. So, while I know this is one of those juicy potential down vote questions, I am just curious as to what everyone else thinks about this topic. Would you tell a high school kid about this? Perhaps if he/she already knows a good deal of programming and loves it he doesn't need a CS degree and could expand his horizons with a liberal arts degree. I know one of the creators of the Django web framework was a American Literature major and he is obviously a pretty gifted developer. Anyway, thanks for the consideration.

  • Exposing an MVC Application Through SharePoint

    - by Damon
    Below you will find my presentation slides and demo files for my SharePoint TechFest 2010 presentation on Exposing an MVC Application through SharePoint.  One of the points I forgot to mention goes back to the performance and licensing benefits of this approach.  If you have a SharePoint box that is completely slammed, you can put the MVC application on a separate web server and essentially offload the application processing to another server.  In terms of licensing, you can leave SharePoint off that new server and just access SharePoint data via web services from the box.  This makes it a lot cheaper if you have MOSS - but if you're just running WSS then it may not have as many cost benefits.  Remember, programming against the web services is not always the easiest thing, so you have to weight the cost/benefit ratio when making such a determination.

  • Can Foswiki be used as a distributed Redmine replacement? [closed]

    - by Tobias Kienzler
    I am quite familiar with and love using git, among other reasons due to its distributed nature. Now I'd like to set up some similarly distributed (FOSS) Project Management software with features similar to what Redmine offers, such as Issue & time tracking, milestones Gantt charts, calendar git integration, maybe some automatic linking of commits and issues Wiki (preferably with Mathjax support) Forum, news, notifications Multiple Projects However, I am looking for a solution that does not require a permanently accesible server, i.e. like in git, each user should have their own copy which can be easily synchronized with others. However it should be possible to not have a copy of every Project on every machine. Since trac uses multiple instances for multiple projects anyway, I was considering using that, but I neither know how well it adapts to simply giting the database itself (which would be be easiest way to handle the distribution due to git being used anyway), nor does it include all of Redmine's feature. After checking http://www.wikimatrix.org for Wikis with integrated tracking system and RCS support, and filtering out seemingly stale project, the choices basically boil down to Foswiki, TWiki and Ikiwiki. The latter doesn't seem to offer as many usability features, and in the TWiki vs Foswiki issue I tend to the latter. Finally, there is Fossil, which starts from the other end by attempting to replace git entirely and tracking itself. I am however not too comfortable with the thought of replacing git, and Fossil's non-SCM features don't seem to be as developed. Now before I invest too much time when someone else might already have tried this, I basically have two questions: Are there crucial features of Project Management software like Redmine that Foswiki does not provide even with all the extensions available? How to set Foswiki up to use git instead of the perl RcsLite?

  • Software Design for Product Verticals and Service Verticals

    - by Rachel
    In every industry there are two verticals Product Vertical and Service Vertical, so my question is: How does design approach changes while designing Software for Product Vertical as compared to developing Software for Service Vertical ? What are the pros and cons for each case ? Also, in case of Product Vertical, How you go about designing Product or Features and what are steps involved ? Lastly, I was reading How Facebook Ships Code article and it appears that Product Managers have very little influence on how Product is developed and responsibility lies mainly with the Developer for the feature. So is this good practice and why one would go for this approach ? What would be your comment on this kind of approach ?

  • Bad style programming, am I pretending too much?

    - by Luca
    I realized to work in an office with a quite bad code base. The base library implemented in years and years is quite limited, and most of that code is, honestly, horrible. Projects developed in the office are very large. Fine. I could define me a "perfectionist" (but often I'm not), and I thought to refactor an application (really a portion), which need a new (complex) feature. But, today, I really realized that it's not possible to refactor that application modules with a reasonable time (say, 24/26 hours, respect the avaialable time for the task, which is 160 hours). I'm talking about (I am a bit ashamed to say) name collisions, large and frequent cut & paste code, horrible and misleading naming, makefiles without dependencies (!), application login is spread randomly across many different sources, dead code, variable aliasing, no assertion, no documentation, very long source files, bad/incomplete include file definition, (this is emblematic!) very frequent extern declaration of variables and functions, ... I'm sure to continue ... buffer overflows because sprintf, indentation (!), spacing, non existent const modifier usage. I would say that every source line was written quite randomly when needed, without keeping in mind some design (at least, the obvious one). (Am I in hell?) The problem arises when the application is developed by a colleague of mine. I felt very frustrated. So, I decided to expose the "situation" to my colleague; at the end, that was a bad idea. He is justified in saying that "the application was developed in haste, so it is natural that it is written vaguely; you are wasting time to think and implement an elegant implementation" .... I'm asking too much from my colleague to write readable code, which is managed and documented? I expect too much in not having to read thousands of lines of code to understand how a particular logic?

  • How to use the AccountsService API with Python?

    - by pabluk
    I'm writing an application for the Ubuntu app showdown and I try to read/write the user's profile picture using this >>> from gi.repository import AccountsService, GLib >>> current_user = GLib.get_user_name() >>> user = AccountsService.UserManager.get_default().get_user(current_user) >>> print user.get_icon_file() None >>> print user.get_user_name() None But apparently does not work. Is there another way to use AccountsService with Python? I could not find more documentation about AccountsService and Python. PS: to test this example you need to install gir1.2-accountsservice-1.0 on Ubuntu 12.04. $ sudo apt-get install gir1.2-accountsservice-1.0

  • learning on the clock

    - by T. Webster
    Some might argue this question is too general, but because keeping up seems especially relevant to programming, is anyone's experience that: do employers expect you to stay current? what is the "industry standard" of expected time a programmer should spend keeping up-to-date? is it generally acceptable that a programmer can spend some time during working hrs on meeting the expectation to keep skills current? If not, how do most programmers find the time? -

  • Can AJAX in a CMS slow down your server

    - by Saif Bechan
    I am currently developing some plugins for WordPress, and I was wondering which route to take. Let's take an example, you want to display the last 3 tweets on your page. Option 1 You do things the normal way inside WordPress. Someone enters the website, while generating the page, you fetch the tweets in php via the twitter api, and just display them where you want. Now the small problem with this is, that you have to wait for the response from twitter. This takes a few ms. NO real problem, but this is question is just out of curiosity. Option 2 Here you don't do anything in WordPress on the initial load, but you do have the API inside. Now you just generate the page, and as soon as the page is done on the client side, you do a small AJAX call back to the server via a WordPress plugin, to fetch your latest tweets. Also called asynchronously. Now the problem with this IMO is that you have much more stress on your server. For starters you have two HTTP requests instead of one. Secondly the WordPress core has to load two times instead of one. Other options Now I know there are a lot of other options: 1) Getting the tweets directly via javascript, no stress on the server at all. 2) Cache the tweets so they are fetched from the DB instead of using the API every time. 3) Getting the tweets from an ajax call that is not a WordPress plugin. 4) Many more. My Question Now my question is if you only compare 1 and 2, which would be a better choice.

  • What are requirements for a successful SOA?

    - by Amir Rezaei
    I’m an EA in an organisation with 10000+ employees. Strategically we are heading towards SOA. Currently I’m researching about SOA’s and creating a road map and I have come over many blogs that talk about “SOA is dead”. We can all agree that SOA is not just web-services. The problem is that I have hard to find any information on the reason behind SOA-fail stories in enterprises. What went bad and what went right? My question is: What are common SOA mistakes in enterprises that make SOA fail in long term? Is the any best practice for SOA? What are the most important requirements for a successful SOA in an enterprise? It would be good feedback towards our SOA strategy in this organisation. I have tried to narrow down the question, but it’s hard due to the nature of the question.

  • How to filter a mysql database with user input on a website and then spit the filtered table back to the website? [migrated]

    - by Luke
    I've been researching this on google for literally 3 weeks, racking my brain and still not quite finding anything. I can't believe this is so elusive. (I'm a complete beginner so if my terminology sounds stupid then that's why.) I have a database in mysql/phpmyadmin on my web host. I'm trying to create a front end that will allow a user to specify criteria for querying the database in a way that they don't have to know sql, basically just combo boxes and checkboxes on a form. Then have this form 'submit' a query to the database, and show the filtered tables. This is how the SQL looks in Microsoft Access: PARAMETERS TEXTINPUT1 Text ( 255 ), NUMBERINPUT1 IEEEDouble; // pops up a list of parameters for the user to input SELECT DISTINCT Table1.Column1, Table1.Column2, Table1.Column3,* // selects only the unique rows in these three columns FROM Table1 // the table where this query is happening WHERE (((Table1.Column1) Like TEXTINPUT1] AND ((Table1.Column2)<=[NUMBERINPUT1] AND ((Table1.Column3)>=[NUMBERINPUT1])); // the criteria for the filter, it's comparing the user input parameters to the data in the rows and only selecting matches according to the equal sign, or greater than + equal sign, or less than + equal sign What I don't get: WHAT IN THE WORLD AM I SUPPOSED TO USE (that isn't totally hard)!? I've tried google fusion tables - doesn't filter right with numerical data or empty cells in rows, can't relate tables I've tried DataTables.net, can't filter right with numerical data and can't use SQL without a bunch of indepth knowledge, not even sure it can if you have that.. I've looked into using jQuery with google spreadsheets, doesn't work at all either I have no idea how I'm supposed to build a front end with my database. Every place that looks promising (like zohocreator) is asking for money, and is far too simplified to be able to do the LIKE criteria or SELECT DISTINCT stuff.

  • How important is responsive web design?

    - by Daniel
    I've heard many different opinions regarding the pros and cons of responsive web design recently and was wondering whether it was necessary for small businesses that target small geographical areas to implement it? Some sub-questions I have relating to this include: Is it better to use responsive web design as opposed to having separate code utilized for different dimensions/devices? Can it affect SEO (positively or negatively)? What are the main problems I could run into when optimizing a website for a business using this design method?

  • How to add new filters to CAML queries in SharePoint 2007

    - by uruit
      Normal 0 21 false false false ES-UY X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin-top:0cm; mso-para-margin-right:0cm; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0cm; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} One flexibility SharePoint has is CAML (Collaborative Application Markup Language). CAML it’s a markup language like html that allows developers to do queries against SharePoint lists, it’s syntax is very easy to understand and it allows to add logical conditions like Where, Contains, And, Or, etc, just like a SQL Query. For one of our projects we have the need to do a filter on SharePoint views, the problem here is that the view it’s a list containing a CAML Query with the filters the view may have, so in order to filter the view that’s already been filtered before, we need to append our filters to the existing CAML Query. That’s not a trivial task because the where statement in a CAML Query it’s like this: <Where>   <And>     <Filter1 />     <Filter2 />   </And> </Where> If we want to add a new logical operator, like an OR it’s not just as simple as to append the OR expression like the following example: <Where>   <And>     <Filter1 />     <Filter2 />   </And>   <Or>     <Filter3 />   </Or> </Where> But instead the correct query would be: <Where>   <Or>     <And>       <Filter1 />       <Filter2 />     </And>     <Filter3 />   </Or> </Where> Notice that the <Filter# /> tags are for explanation purpose only. In order to solve this problem we created a simple component, it has a method that receives the current query (could be an empty query also) and appends the expression you want to that query. Example: string currentQuery = @“ <Where>    <And>     <Contains><FieldRef Name='Title' /><Value Type='Text'>A</Value></Contains>     <Contains><FieldRef Name='Title' /><Value Type='Text'>B</Value></Contains>   </And> </Where>”; currentQuery = CAMLQueryBuilder.AppendQuery(     currentQuery,     “<Contains><FieldRef Name='Title' /><Value Type='Text'>C</Value></Contains>”,     CAMLQueryBuilder.Operators.Or); The fist parameter this function receives it’s the actual query, the second it’s the filter you want to add, and the third it’s the logical operator, so basically in this query we want all the items that the title contains: the character A and B or the ones that contains the character C. The result query is: <Where>   <Or>      <And>       <Contains><FieldRef Name='Title' /><Value Type='Text'>A</Value></Contains>       <Contains><FieldRef Name='Title' /><Value Type='Text'>B</Value></Contains>     </And>     <Contains><FieldRef Name='Title' /><Value Type='Text'>C</Value></Contains>   </Or> </Where>             The code:   First of all we have an enumerator inside the CAMLQueryBuilder class that has the two possible Options And, Or. public enum Operators { And, Or }   Then we have the main method that’s the one that performs the append of the filters. public static string AppendQuery(string containerQuery, string logicalExpression, Operators logicalOperator){   In this method the first we do is create a new XmlDocument and wrap the current query (that may be empty) with a “<Query></Query>” tag, because the query that comes with the view doesn’t have a root element and the XmlDocument must be a well formatted xml.   XmlDocument queryDoc = new XmlDocument(); queryDoc.LoadXml("<Query>" + containerQuery + "</Query>");   The next step is to create a new XmlDocument containing the logical expression that has the filter needed.   XmlDocument logicalExpressionDoc = new XmlDocument(); logicalExpressionDoc.LoadXml("<root>" + logicalExpression + "</root>"); In these next four lines we extract the expression from the recently created XmlDocument and create an XmlElement.                  XmlElement expressionElTemp = (XmlElement)logicalExpressionDoc.SelectSingleNode("/root/*"); XmlElement expressionEl = queryDoc.CreateElement(expressionElTemp.Name); expressionEl.InnerXml = expressionElTemp.InnerXml;   Below are the main steps in the component logic. The first “if” checks if the actual query doesn’t contains a “Where” clause. In case there’s no “Where” we add it and append the expression.   In case that there’s already a “Where” clause, we get the entire statement that’s inside the “Where” and reorder the query removing and appending elements to form the correct query, that will finally filter the list.   XmlElement whereEl; if (!containerQuery.Contains("Where")) { queryDoc.FirstChild.AppendChild(queryDoc.CreateElement("Where")); queryDoc.SelectSingleNode("/Query/Where").AppendChild(expressionEl); } else { whereEl = (XmlElement)queryDoc.SelectSingleNode("/Query/Where"); if (!containerQuery.Contains("<And>") &&                 !containerQuery.Contains("<Or>"))        {              XmlElement operatorEl = queryDoc.CreateElement(GetName(logicalOperator)); XmlElement existingExpression = (XmlElement)whereEl.SelectSingleNode("/Query/Where/*"); whereEl.RemoveChild(existingExpression);                 operatorEl.AppendChild(existingExpression);               operatorEl.AppendChild(expressionEl);                 whereEl.AppendChild(operatorEl);        }        else        {              XmlElement operatorEl = queryDoc.CreateElement(GetName(logicalOperator)); XmlElement existingOperator = (XmlElement)whereEl.SelectSingleNode("/Query/Where/*");                 whereEl.RemoveChild(existingOperator);               operatorEl.AppendChild(existingOperator);               operatorEl.AppendChild(expressionEl);                 whereEl.AppendChild(operatorEl);         }  }  return queryDoc.FirstChild.InnerXml }     Finally the GetName method converts the Enum option to his string equivalent.   private static string GetName(Operators logicalOperator) {       return Enum.GetName(typeof(Operators), logicalOperator); }        This component helped our team a lot using SharePoint 2007 and modifying the queries, but now in SharePoint 2010; that wouldn’t be needed because of the incorporation of LINQ to SharePoint. This new feature enables the developers to do typed queries against SharePoint lists without the need of writing any CAML code.   Normal 0 21 false false false ES-UY X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi; mso-fareast-language:EN-US;} Post written by Sebastian Rodriguez - Portals and Collaboration Solutions @ UruIT

  • Technologie Roadmap: Portlet JSR286 vs Widget/Gadget

    - by Aerosteak
    Hello IBM got me confused (again). For many years IBM have been pushing for Portlet Containers with the JSR 168 and later the JSR 286 Specification. 2008-2009, IBM the Lotus division introduced the iWidget Specification. Based on my reading, it is a more dynamic and lightweight version of the Portlets, close to Google Gadget. It uses a different paradigm than Porlet while providing the same features. A major differentiator with this kind of client side technologies is that you don’t need a big and costly Portal infrastructure.

  • The University with the best Computer Science degree?

    - by Shinnok
    Which University provides the best Computer Science degree in your opinion(non US Universities welcomed too)? I do realize that you most probably didn't attend more then one University so you can't really provide a truly insightful opinion on several institutions, but what you can do instead, is describe the one you attended and outline it's strengths and weaknesses. What do i mean by the best is essentially the University that upon graduation and given a subject's assumed reasonable level of passion and interest in the field, one can trust upon the fact he was at least exposed to the best and most deep, correct and up to date courses on Programming, Operating Systems, Internet and Computer Technology overall. We have all heard of recent horror stories in Computer Science teaching, thus an exposure the best of the best, essentially the University you would grant your children to if they were to be interested into this field, would be a great thing.

  • When is your interview?

    - by Rob Farley
    Sometimes it’s tough to evaluate someone – to figure out if you think they’d be worth hiring. These days, since starting LobsterPot Solutions, I have my share of interviews, on both sides of the desk. Sometimes I’m checking out potential staff members; sometimes I’m persuading someone else to get us on board for a project. Regardless of who is on which side of the desk, we’re both checking each other out. The world is not how it was some years ago. I’m pretty sure that every time I walk into a room for an interview, I’ve searched for them online, and they’ve searched for me. I suspect they usually have the easier time finding me, although there are obviously other Rob Farleys in the world. They may have even checked out some of my presentations from conferences, read my blog posts, maybe even heard me tell jokes or sing. I know some people need me to explain who I am, but for the most part, I think they’ve done plenty of research long before I’ve walked in the room. I remember when this was different (as it could be for you still). I remember a time when I dealt with recruitment agents, looking for work. I remember sitting in rooms having been giving a test designed to find out if I knew my stuff or not, and then being pulled into interviews with managers who had to find out if I could communicate effectively. I’d need to explain who I was, what kind of person I was, what my value-system involved, and so on. I’m sure you understand what I’m getting at. (Oh, and in case you hadn’t realised, it’s a T-SQL Tuesday post, this month about interviews.) At TechEd Australia some years ago (either 2009 or 2010 – I forget which), I remember hearing a comment made during the ‘locknote’, the closing session. The presenter described a conversation he’d heard between two girls, discussing a guy that one of them had just started dating. The other girl expressed horror at the fact that her friend had met this guy in person, rather than through an online dating agency. The presenter pointed out that people realise that there’s a certain level of safety provided through the checks that those sites do. I’m not sure I completely trust this, but I’m sure it’s true for people’s technical profiles. If I interview someone, I hope they have a profile. I hope I can look at what they already know. I hope I can get samples of their work, and see how they communicate. I hope I can get a feel for their sense of humour. I hope I already know exactly what kind of person they are – their value system, their beliefs, their passions. Even their grammar. I can work out if the person is a good risk or not from who they are online. If they don’t have an online presence, then I don’t have this information, and the risk is higher. So if you’re interviewing with me, your interview started long before the conversation. I hope it started before I’d ever heard of you. I know the interview in which I’m being assessed started before I even knew there was a product called SQL Server. It’s reflected in what I write. It’s in the way I present. I have spent my life becoming me – so let’s talk! @rob_farley

  • Cloud Evolving, SQL Server Responding

    - by KKline
    Brent Ozar ( blog | twitter ) and I did an interview with TechTarget’s Brendan Cournoyer at last summer's Tech-Ed, which as turned into a podcast titled “Cloud efforts advance, SQL Server evolves.” The podcast covers all the major trends at the conference (like BI), virtualization features in Quest’s products (like Spotlight), Brent’s new book and MCM certification, and more. Here’s a link to hear it, appearing on 6/11/10: http://searchsqlserver.techtarget.com/podcast/Cloud-efforts-advance-SQL-Server-evolves....(read more)

  • 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?
