  • Amanda Todd&ndash;What Parents Can Learn From Her Story

    - by D'Arcy Lussier
    Amanda Todd was a bullied teenager who committed suicide this week. Her story has become headline news due in part to her You Tube video she posted telling her story:   The story is heartbreaking for so many reasons, but I wanted to talk about what we as parents can learn from this. Being the dad to two girls, one that’s 10, I’m very aware of the dangers that the internet holds. When I saw her story, one thing jumped out at me – unmonitored internet access at an early age. My daughter (then 9) came home from a friends place once and asked if she could be in a YouTube video with her friend. Apparently this friend was allowed to do whatever she wanted on the internet, including posting goofy videos. This set off warning bells and we ensured our daughter realized the dangers and that she was not to ever post videos of herself. In looking at Amanda’s story, the access to unmonitored internet time along with just being a young girl and being flattered by an online predator were the key events that ultimately led to her suicide. Yes, the reaction of her classmates and “friends” was horrible as well, I’m not diluting that. But our youth don’t fully understand yet that what they do on the internet today will follow them potentially forever. And the people they meet online aren’t necessarily who they claim to be. So what can we as parents learn from Amanda’s story? Parents Shouldn’t Feel Bad About Being Internet Police Our job as parents is in part to protect our kids and keep them safe, even if they don’t like our measures. This includes monitoring, supervising, and restricting their internet activities. In our house we have a family computer in the living room that the kids can watch videos and surf the web. It’s in plain view of everyone, so you can’t hide what you’re looking at. If our daughter goes to a friend’s place, we ask about what they did and what they played. If the computer comes up, we ask about what they did on it. Luckily our daughter is very up front and honest in telling us things, so we have very open discussions. Parents Need to Be Honest About the Dangers of the Internet I’m sure every generation says that “kids grow up so fast these days”, but in our case the internet really does push our kids to be exposed to things they otherwise wouldn’t experience. One wrong word in a Google search, a click of a link in a spam email, or just general curiosity can expose a child to things they aren’t ready for or should never be exposed to (and I’m not just talking about adult material – have you seen some of the graphic pictures from war zones posted on news sites recently?). Our stance as parents has been to be open about discussing the dangers with our kids before they encounter any content – be proactive instead of reactionary. Part of this is alerting them to the monsters that lurk on the internet as well. As kids explore the world wide web, they’re eventually going to encounter some chat room or some Facebook friend invite or other personal connection with someone. More than ever kids need to be educated on the dangers of engaging with people online and sharing personal information. You can think of it as an evolved discussion that our parents had with us about using the phone: “Don’t say ‘I’m home alone’, don’t say when mom or dad get home, don’t tell them any information, etc.” Parents Need to Talk Self Worth at Home Katie makes the point better than I ever could (one bad word towards the end): Our children need to understand their value beyond what the latest issue of TigerBeat says, or the media who continues flaunting physical attributes over intelligence and character, or a society that puts focus on status and wealth. They also have to realize that just because someone pays you a compliment, that doesn’t mean you should ignore personal boundaries and limits. What does this have to do with the internet? Well, in days past if you wanted to be social you had to go out somewhere. Now you can video chat with any number of people from the comfort of wherever your laptop happens to be – and not just text but full HD video with sound! While innocent children head online in the hopes of meeting cool people, predators with bad intentions are heading online too. As much as we try to monitor their online activity and be honest about the dangers of the internet, the human side of our kids isn’t something we can control. But we can try to influence them to see themselves as not needing to search out the acceptance of complete strangers online. Way easier said than done, but ensuring self-worth is something discussed, encouraged, and celebrated is a step in the right direction. Parental Wake Up Call This post is not a critique of Amanda’s parents. The reality is that cyber bullying/abuse is happening every day, and there are millions of parents that have no clue its happening to their children. Amanda’s story is a wake up call that our children’s online activities may be putting them in danger. My heart goes out to the parents of this girl. As a father of daughters, I can’t imagine what I would do if I found my daughter having to hide in a ditch to avoid a mob or call 911 to report my daughter had attempted suicide by drinking bleach or deal with a child turning to drugs/alcohol/cutting to cope. It would be horrendous if we as parents didn’t re-evaluate our family internet policies in light of this event. And in the end, Amanda’s video was meant to bring attention to her plight and encourage others going through the same thing. We may not be kids, but we can still honour her memory by helping safeguard our children.

  • Ongoing confusion about ivars and properties in objective C

    - by Earl Grey
    After almost 8 months being in ios programming, I am again confused about the right approach. Maybe it is not the language but some OOP principle I am confused about. I don't know.. I was trying C# a few years back. There were fields (private variables, private data in an object), there were getters and setters (methods which exposed something to the world) ,and properties which was THE exposed thing. I liked the elegance of the solution, for example there could be a class that would have a property called DailyRevenue...a float...but there was no private variable called dailyRevenue, there was only a field - an array of single transaction revenues...and the getter for DailyRevenue property calculated the revenue transparently. If somehow the internals of daily revenue calculation would change, it would not affect somebody who consumed my DailyRevenue property in any way, since he would be shielded from getter implementation. I understood that sometimes there was , and sometimes there wasn't a 1-1 relationship between fields and properties. depending on the requirements. It seemed ok in my opinion. And that properties are THE way to acces the data in object. I know the difference betweeen private, protected, and public keyword. Now lets get to objectiveC. On what factor should I base my decision about making someting only an ivar or making it as a property? Is the mental model the same as I describe above? I know that ivars are "protected" by default, not "private" asi in c#..But thats ok I think, no big deal for my presnet level of understanding the whole ios development. The point is ivars are not accesible from outside (given i don't make them public..but i won't). The thing that clouds my clear understanding is that I can have IBOutlets from ivars. Why am I seeing internal object data in the UI? *Why is it ok?* On the other hand, if I make an IBOutlet from property, and I do not make it readonly, anybody can change it. Is this ok too? Let's say I have a ParseManager object. This object would use a built in Foundation framework class called NSXMLParser. Obviously my ParseManager will utilize this nsxmlparser's capabilities but will also do some additional work. Now my question is, who should initialize this NSXMLParser object and in which way should I make a reference to it from the ParseManager object, when there is a need to parse something. A) the ParseManager -1) in its default init method (possible here ivar - or - ivar+ppty) -2) with lazyloading in getter (required a ppty here) B) Some other object - who will pass a reference to NSXMLParser object to the ParseManager object. -1) in some custom initializer (initWithParser:(NSXMLPArser *) parser) when creating the ParseManager object.. A1 - the problem is, we create a parser and waste memory while it is not yet needed. However, we can be sure that all methods that are part ot ParserManager object, can use the ivar safely, since it exists. A2 - the problem is, the nsxmlparser is exposed to outside world, although it could be read only. Would we want a parser to be exposed in some scenario? B1 - this could maybe be useful when we would want to use more types of parsers..i dont know... I understand that architectural requirements and and language is not the same. But clearly the two are in relation. How to get out of that mess of my? Please bear with me, I wasn't able to come up with a single ultimate question. And secondly, it's better to not scare me with some superadvanced newspeak that talks about some crazy internals (what the compiler does) and edge cases.

  • Web Application Tasks Estimation

    - by Ali
    I know the answer depends on the exact project and its requirements but i am asking on the avarage % of the total time goes into the tasks of the web application development statistically from your own experiance. While developing a web application (database driven) How much % of time does each of the following activities usually takes: -- database creation & all related stored procedures -- server side development -- client side development -- layout settings and designing I know there are lots of great web application developers around here and each one of you have done fair amount of web development and as a result there could be an almost fixed percentage of time going to each of the above activities of web developments for standard projects Update : I am not expecting someone to tell me number of hours i am asking about the average percentage of time that goes on each of the activities as per your experience i.e. server side dev 50%, client side development 20% ,,,,, I repeat there will be lots of cases that differs from the standard depending on the exact requirments of each web application project but here i am asking about Avarage for standard (no special requirment) web project

  • Cheap, Awesome, Programmer-friendly City in Europe for 1 year Study Hiatus?

    - by Gonjasufi
    Next year I'll be 21. I'll have 3 years of professional experience under my belt (with a one year break as a soldier). I'm planning to take 2 to 3 years off. Instead of going to a university I'm planning to work on personal projects and learn on my own. I'm looking for suggestions of great, cheap, programmer-friendly (e.g. lots of cafes, ordered food, parks, blazing fast internet connection, wifi, lots of people that speak English) cities around the world, (and specifically in Europe as I also have european citizenship). If you can supply with an estimate cost of living for that city, or a site for comparisons that will also be great. edit: I'm living in Tel Aviv, ~20 highest cost of living city in the world, so statistically speaking almost all the cities are cheaper.

  • google changing crawl speed: doesn't seem to work. Why?

    - by Olivier Pons
    I've changed 3 days ago the google crawling speed of mywebsite. Here it is: This means: 2 demands by second. I've got the message on the google webmasters tools that the change speed has been taken in account: But after more than three days, nothing happens: still one request every ten seconds See here: My webserver is very fast and can handle up to twenty simultaneous connexions. And my website is brand new, this means google is almost the only one here crawling my website. After more than 30000 successful requests (= no 404), I think there's something going on... or maybe this is just a bug? Has anyone ever had this problem?

  • Sea Monkey Sales & Marketing, and what does that have to do with ERP?

    - by user709270
    Tier One Defined By Lyle Ekdahl, Oracle JD Edwards Group Vice President and General Manager  I recently became aware of the latest Sea Monkey Sales & Marketing tactic. Wait now, what is Sea Monkey Sales & Marketing and what does that have to do with ERP? Well if you grew up in USA during the 50’s, 60’s and maybe a bit in the early 70’s there was a unifying media of culture known as the comic book. I was a big Iron Man fan. I always liked the troubled hero aspect of Tony Start and hey he was a technologist. This is going somewhere, just hold on. Of course comic books like most media contained advertisements. Ninety pound weakling transformed by Charles Atlas in just 15 minutes per day. Baby Ruth, Juicy Fruit Gum and all assortments of Hostess goodies were on display. The best ad was for the “Amazing Live Sea-Monkeys – The real live fun-pets you grow yourself!” These ads set the standard for exaggeration and half-truth; “…they love attention…so eager to please, they can even be trained…” The cartoon picture on the ad is of a family of royal looking sea creatures – daddy, mommy, son and little sis – sea monkey? There was a disclaimer at the bottom in fine print, “Caricatures shown not intended to depict Artemia.” Ok what ten years old knows what the heck artemia is? Well you grow up fast once you’ve been separated from your buck twenty five plus postage just to discover that it is brine shrimp. Really dumb brine shrimp that don’t take commands or do tricks. Unfortunately the technology industry is full of sea monkey sales and marketing. Yes believe it or not in some cases there is subterfuge and obfuscation used to secure contracts. Hey I get it; the picture on the box might not be the actual size. Make up what you want about your product, but here is what I don’t like, could you leave out the obvious falsity when it comes to my product, especially the negative stuff. So here is the latest one – “Oracle’s JD Edwards is NOT tier one”. Really? Definition please! Well a whole host of googleable and reputable sources confirm that a tier one vendor is large, well known, and enjoys national and international recognition. Let me see large, so thousands of customers? Oh and part of the world’s largest business software and hardware corporation? Check and check JD Edwards has that and that. Well known, enjoying national and international recognition? Oracle’s JD Edwards EnterpriseOne is available in 21 languages and is directly localized in 33 countries that support some of the world’s largest multinationals and many midsized domestic market companies. Something on the order of half the JD Edwards customer base is outside North America. My passport is on its third insert after 2 years and not from vacations. So if you don’t mind I am going to mark national and international recognition in the got it column. So what else is there? Well let me offer a few criteria. Longevity – The JD Edwards products benefit from 35+ years of intellectual property development; through booms, busts, mergers and acquisitions, we are still here Vision & innovation – JD Edwards is the first full suite ERP to run on the iPad as just one example Proven track record of execution – Since becoming part of Oracle, JD Edwards has released to the market over 20 deliverables including major release, point releases, new apps modules, tool releases, integrations…. Solid, focused functionality with a flexible, interoperable, extensible underlying architecture – JD Edwards offers solid core ERP with specialty modules for verticals all delivered on a well defined independent tools layer that helps enable you to scale your business without an ERP reimplementation A continuation plan – Oracle’s JD Edwards offers our customers a 6 year roadmap as well as interoperability with Oracle’s next generation of applications Oh I almost forgot that the expert sources agree on one additional thing, tier one may be a preferred vendor that offers product and services to you with appealing value. You should check out the TCO studies of JD Edwards. I think you will see what the thousands of customers that rely on these products to run their businesses enjoy – that is the tier one solution with the lowest TCO. Oh and if you get an offer to buy an ERP for no license charge, remember the picture on the box might not be the actual size.

  • Don't Use Static? [closed]

    - by Joshiatto
    Possible Duplicate: Is static universally “evil” for unit testing and if so why does resharper recommend it? Heavy use of static methods in a Java EE web application? I submitted an application I wrote to some other architects for code review. One of them almost immediately wrote me back and said "Don't use "static". You can't write automated tests with static classes and methods. "Static" is to be avoided." I checked and fully 1/4 of my classes are marked "static". I use static when I am not going to create an instance of a class because the class is a single global class used throughout the code. He went on to mention something involving mocking, IOC/DI techniques that can't be used with static code. He says it is unfortunate when 3rd party libraries are static because of their un-testability. Is this other architect correct?

  • Performing a clean database creation using msbuild

    - by Robert May
    So I’m taking a break from writing about other Agile stuff for a post. :)  I’m still going to get back to the other subjects, but this is fun too. Something I’ve done quite a bit of is MSBuild and CI work.  I’m experimenting with ways to improve what I’ve done in the past, particularly around database CI. Today, I developed a mechanism for starting from scratch with your database.  By scratch, I mean blowing away the existing database and creating it again from a single command line call.  I’m a firm believer that developers should be able to get to a known clean state at the database level with a single command and that they should be operating off of their own isolated database to improve productivity.  These scripts will help that. Here’s how I did it.  First, we have to disconnect users.  I did so using the help of a script from sql server central.  Note that I’m using sqlcmd variable replacement. -- kills all the users in a particular database -- dlhatheway/3M, 11-Jun-2000 declare @arg_dbname sysname declare @a_spid smallint declare @msg varchar(255) declare @a_dbid int set @arg_dbname = '$(DatabaseName)' select @a_dbid = sdb.dbid from master..sysdatabases sdb where sdb.name = @arg_dbname declare db_users insensitive cursor for select sp.spid from master..sysprocesses sp where sp.dbid = @a_dbid open db_users fetch next from db_users into @a_spid while @@fetch_status = 0 begin select @msg = 'kill '+convert(char(5),@a_spid) print @msg execute (@msg) fetch next from db_users into @a_spid end close db_users deallocate db_users GO Once all users are booted from the database, we can commence with recreating the database.  I generated the script that is used to create a database from SQL Server management studio, so I’m only going to show the bits that weren’t generated that are important.  There are a bunch of Alter Database statements that aren’t shown. First, I had to find the default location of the database files in the install, since they can be in many different locations.  I used Method 1 from a technet blog and then modified it a bit to do what I needed to do.  I ended up using dynamic SQL because for the life of me, I couldn’t get the “Filename” property to not return an error when I used anything besides a string.  I’m dropping the database first, if it exists.  Here’s the code:   IF EXISTS(SELECT 1 FROM [master].[sys].[databases] WHERE [name] = N'$(DatabaseName)') BEGIN drop database $(DatabaseName) END; go IF EXISTS(SELECT 1 FROM [master].[sys].[databases] WHERE [name] = 'zzTempDBForDefaultPath') BEGIN DROP DATABASE zzTempDBForDefaultPath END; -- Create temp database. Because no options are given, the default data and --- log path locations are used CREATE DATABASE zzTempDBForDefaultPath; DECLARE @Default_Data_Path VARCHAR(512), @Default_Log_Path VARCHAR(512); --Get the default data path SELECT @Default_Data_Path = ( SELECT LEFT(physical_name,LEN(physical_name)-CHARINDEX('\',REVERSE(physical_name))+1) FROM sys.master_files mf INNER JOIN sys.[databases] d ON mf.[database_id] = d.[database_id] WHERE d.[name] = 'zzTempDBForDefaultPath' AND type = 0); --Get the default Log path SELECT @Default_Log_Path = ( SELECT LEFT(physical_name,LEN(physical_name)-CHARINDEX('\',REVERSE(physical_name))+1) FROM sys.master_files mf INNER JOIN sys.[databases] d ON mf.[database_id] = d.[database_id] WHERE d.[name] = 'zzTempDBForDefaultPath' AND type = 1); --Clean up. IF EXISTS(SELECT 1 FROM [master].[sys].[databases] WHERE [name] = 'zzTempDBForDefaultPath') BEGIN DROP DATABASE zzTempDBForDefaultPath END; DECLARE @SQL nvarchar(max) SET @SQL= 'CREATE DATABASE $(DatabaseName) ON PRIMARY ( NAME = N''$(DatabaseName)'', FILENAME = N''' + @Default_Data_Path + N'$(DatabaseName)' + '.mdf' + ''', SIZE = 2048KB , FILEGROWTH = 1024KB ) LOG ON ( NAME = N''$(DatabaseName)Log'', FILENAME = N''' + @Default_Log_Path + N'$(DatabaseName)' + '.ldf' + ''', SIZE = 1024KB , FILEGROWTH = 10%) ' exec (@SQL) GO And with that, your database is created.  You can run these scripts on any server and on any database name.  To do that, I created an MSBuild script that looks like this: <Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003" ToolsVersion="4.0"> <PropertyGroup> <DatabaseName>MyDatabase</DatabaseName> <Server>localhost</Server> <SqlCmd>sqlcmd -v DatabaseName=$(DatabaseName) -S $(Server) -i </SqlCmd> <ScriptDirectory>.\Scripts</ScriptDirectory> </PropertyGroup> <Target Name ="Rebuild"> <ItemGroup> <ScriptFiles Include="$(ScriptDirectory)\*.sql"/> </ItemGroup> <Exec Command="$(SqlCmd) &quot;%(ScriptFiles.Identity)&quot;" ContinueOnError="false"/> </Target> </Project> Note that the Scripts directory is underneath the directory where I’m running the msbuild command and is relative to that directory.  Note also that the target is using batching to run each script in the scripts subdirectory, one after the other.  Each script is passed to the sqlcmd command line execution using the .Identity property on the itemgroup that is created.  This target file is saved in the file “Database.target”. To make this work, you’ll need msbuild in your path, and then run the following command: msbuild database.target /target:Rebuild Once you’ve got your virgin database setup, you’d then need to use a tool like dbdeploy.net to determine that it was a virgin database, build a change script based on the change scripts, and then you’d want another sqlcmd call to update the database with the appropriate scripts.  I’m doing that next, so I’ll post a blog update when I’ve got it working.

  • Using SQL Source Control with Fortress or Vault &ndash; Part 1

    - by AjarnMark
    I am fanatical when it comes to managing the source code for my company.  Everything that we build (in source form) gets put into our source control management system.  And I’m not just talking about the UI and middle-tier code written in C# and ASP.NET, but also the back-end database stuff, which at times has been a pain.  We even script out our Scheduled Jobs and keep a copy of those under source control. The UI and middle-tier stuff has long been easy to manage as we mostly use Visual Studio which has integration with source control systems built in.  But the SQL code has been a little harder to deal with.  I have been doing this for many years, well before Microsoft came up with Data Dude, so I had already established a methodology that, while not as smooth as VS, nonetheless let me keep things well controlled, and allowed doing my database development in my tool of choice, Query Analyzer in days gone by, and now SQL Server Management Studio.  It just makes sense to me that if I’m going to do database development, let’s use the database tool set.  (Although, I have to admit I was pretty impressed with the demo of Juneau that Don Box did at the PASS Summit this year.)  So as I was saying, I had developed a methodology that worked well for us (and I’ll probably outline in a future post) but it could use some improvement. When Solutions and Projects were first introduced in SQL Management Studio, I thought we were finally going to get our same experience that we have in Visual Studio.  Well, let’s say I was underwhelmed by Version 1 in SQL 2005, and apparently so were enough other people that by the time SQL 2008 came out, Microsoft decided that Solutions and Projects would be deprecated and completely removed from a future version.  So much for that idea. Then I came across SQL Source Control from Red-Gate.  I have used several tools from Red-Gate in the past, including my favorites SQL Compare, SQL Prompt, and SQL Refactor.  SQL Prompt is worth its weight in gold, and the others are great, too.  Earlier this year, we upgraded from our earlier product bundles to the new Developer Bundle, and in the process added SQL Source Control to our collection.  I thought this might really be the golden ticket I was looking for.  But my hopes were quickly dashed when I discovered that it only integrated with Microsoft Team Foundation Server and Subversion as the source code repositories.  We have been using SourceGear’s Vault and Fortress products for years, and I wholeheartedly endorse them.  So I was out of luck for the time being, although there were a number of people voting for Vault/Fortress support on their feedback forum (as did I) so I had hope that maybe next year I could look at it again. But just a couple of weeks ago, I was pleasantly surprised to receive notice in my email that Red-Gate had an Early Access version of SQL Source Control that worked with Vault and Fortress, so I quickly downloaded it and have been putting it through its paces.  So far, I really like what I see, and I have been quite impressed with Red-Gate’s responsiveness when I have contacted them with any issues or concerns that I have had.  I have had several communications with Gyorgy Pocsi at Red-Gate and he has been immensely helpful and responsive. I must say that development with SQL Source Control is very different from what I have been used to.  This post is getting long enough, so I’ll save some of the details for a separate write-up, but the short story is that in my regular mode, it’s all about the script files.  Script files are King and you dare not make a change to the database other than by way of a script file, or you are in deep trouble.  With SQL Source Control, you make your changes to your development database however you like.  I still prefer writing most of my changes in T-SQL, but you can also use any of the GUI functionality of SSMS to make your changes, and SQL Source Control “manages” the script for you.  Basically, when you first link your database to source control, the tool generates scripts for every primary object (tables and their indexes are together in one script, not broken out into separate scripts like DB Projects do) and those scripts are checked into your source control.  So, if you needed to, you could still do a GET from your source control repository and build the database from scratch.  But for the day-to-day work, SQL Source Control uses the same technique as SQL Compare to determine what changes have been made to your development database and how to represent those in your repository scripts.  I think that once I retrain myself to just work in the database and quit worrying about having to find and open the right script file, that this will actually make us more efficient. And for deployment purposes, SQL Source Control integrates with the full SQL Compare utility to produce a synchronization script (or do a live sync).  This is similar in concept to Microsoft’s DACPAC, if you’re familiar with that. If you are not currently keeping your database development efforts under source control, definitely examine this tool.  If you already have a methodology that is working for you, then I still think this is worth a review and comparison to your current approach.  You may find it more efficient.  But remember that the version which integrates with Vault/Fortress is still in pre-release mode, so treat it with a little caution.  I have found it to be fairly stable, but there was one bug that I found which had inconvenient side-effects and could have really been frustrating if I had been running this on my normal active development machine.  However, I can verify that that bug has been fixed in a more recent build version (did I mention Red-Gate’s responsiveness?).

  • SQLBeat Podcast – Episode 8 – Interviewing Patrick LeBlanc On Interviewing

    - by SQLBeat
    In this episode of the SQLBeat Podcast (@SQLBeat on twitter) I had a chance to speak with Patrick LeBlanc, currently with Microsoft and former SQL Server MVP. We spend a good amount of time talking about his current gig and his apparent fascination with almost never being dressed. Fortunately he had on some jeans and a shirt for this interview, though he did look at bit dozy because he had not slept the night before. With his help we came up with what is going to be a recurring section on the podcast and that is failed or embarrassing job interviews. Patrick has quite a humiliating one for the launch of “Tell Me About Your Worst Job Interview”. Ok, I can come up with a better title for that section surely. Anyway, have a listen and if you can think of something better, let me know in the comments section. <source src="http://www.simple-talk.com/blogbits/rodneylandrum/Patrick_LeBlanc.ogg" type="audio/ogg; codecs="vorbis"

  • Anyone know how to get an LTSP image working with VIA VX855 chipset?

    - by Bryan
    I'm running an LTSP server on Ubuntu 11.10 and can load the i386 image via PXE boot on a VirtualBox VM just fine. However, when I PXE boot a Dell FX130 thin client on the LTSP network the login screen ends up being a white screen with a bunch of wavy black lines going up and down it. The 11.10 splash screen displays just fine as the image is booted, then I get a "INVALID CARD NUMBER" message, then a black screen, then finally the white screen with wavy lines. I'm not sure if the "INVALID CARD NUMBER" message has anything to do with the issue, but in the end the white screen with wavy lines makes me think it's a video driver problem. On the LTSP server, I chrooted into /opt/ltsp/i386 and made sure xserver-xorg-video-openchrome was installed. I did notice that no xorg.conf exits in /etc/X11 though.

  • Tuning Red Gate: #4 of Some

    - by Grant Fritchey
    First time connecting to these servers directly (keys to the kingdom, bwa-ha-ha-ha. oh, excuse me), so I'm going to take a look at the server properties, just to see if there are any issues there. Max memory is set, cool, first possible silly mistake clear. In fact, these look to be nicely set up. Oh, I'd like to see the ANSI Standards set by default, but it's not a big deal. The default location for database data is the F:\ drive, where I saw all the activity last time. Cool, the people maintaining the servers in our company listen, parallelism threshold is set to 35 and optimize for ad hoc is enabled. No shocks, no surprises. The basic setup is appropriate. On to the problem database. Nothing wrong in the properties. The database is in SIMPLE recovery, but I think it's a reporting system, so no worries there. Again, I'd prefer to see the ANSI settings for connections, but that's the worst thing I can see. Time to look at the queries, tables, indexes and statistics because all the information I've collected over the last several days suggests that we're not looking at a systemic problem (except possibly not enough memory), but at the traditional tuning issues. I just want to note that, I started looking at the system, not the queries. So should you when tuning your environment. I know, from the data collected through SQL Monitor, what my top poor performing queries are, and the most frequently called, etc. I'm starting with the most frequently called. I'm going to get the execution plan for this thing out of the cache (although, with the cache dumping constantly, I might not get it). And it's not there. Called 1.3 million times over the last 3 days, but it's not in cache. Wow. OK. I'll see what's in cache for this database: SELECT  deqs.creation_time,         deqs.execution_count,         deqs.max_logical_reads,         deqs.max_elapsed_time,         deqs.total_logical_reads,         deqs.total_elapsed_time,         deqp.query_plan,         SUBSTRING(dest.text, (deqs.statement_start_offset / 2) + 1,                   (deqs.statement_end_offset - deqs.statement_start_offset) / 2                   + 1) AS QueryStatement FROM    sys.dm_exec_query_stats AS deqs         CROSS APPLY sys.dm_exec_sql_text(deqs.sql_handle) AS dest         CROSS APPLY sys.dm_exec_query_plan(deqs.plan_handle) AS deqp WHERE   dest.dbid = DB_ID('Warehouse') AND deqs.statement_end_offset > 0 AND deqs.statement_start_offset > 0 ORDER BY deqs.max_logical_reads DESC ; And looking at the most expensive operation, we have our first bad boy: Multiple table scans against very large sets of data and a sort operation. a sort operation? It's an insert. Oh, I see, the table is a heap, so it's doing an insert, then sorting the data and then inserting into the primary key. First question, why isn't this a clustered index? Let's look at some more of the queries. The next one is deceiving. Here's the query plan: You're thinking to yourself, what's the big deal? Well, what if I told you that this thing had 8036318 reads? I know, you're looking at skinny little pipes. Know why? Table variable. Estimated number of rows = 1. Actual number of rows. well, I'm betting several more than one considering it's read 8 MILLION pages off the disk in a single execution. We have a serious and real tuning candidate. Oh, and I missed this, it's loading the table variable from a user defined function. Let me check, let me check. YES! A multi-statement table valued user defined function. And another tuning opportunity. This one's a beauty, seriously. Did I also mention that they're doing a hash against all the columns in the physical table. I'm sure that won't lead to scans of a 500,000 row table, no, not at all. OK. I lied. Of course it is. At least it's on the top part of the Loop which means the scan is only executed once. I just did a cursory check on the next several poor performers. all calling the UDF. I think I found a big tuning opportunity. At this point, I'm typing up internal emails for the company. Someone just had their baby called ugly. In addition to a series of suggested changes that we need to implement, I'm also apologizing for being such an unkind monster as to question whether that third eye & those flippers belong on such an otherwise lovely child.

  • GWB | Administrator Blog Is Back To Life

    - by Jeff Julian
    We are bringing back the administrator’s blog for Geekswithblogs.net as a place to get information for what is going on with GWB. Couple reasons we are doing this. One, I post a lot of information on my blog that is not Geekswithblogs.net related. Most the time it isn’t even developer related and I know I need to work on that too, but in an effort to keep the signal much higher than the noise, we are moving the information over there. The blog URL is http://geekswithblogs.net/administrator. The other reason we are doing it is I am not the only member of the GWB staff. So please subscribe to that blog and let us know what you think about Geekswithblogs.net and how we can make the site better.http://geekswithblogs.net/administrator

  • How to autohide Unity 2D?

    - by ph1b
    In the regular Unity 3D, I used Compiz Config Manager where I could config the Unity-Plugin to autohide the left start-bar and not to show it when moving my mouse to the left. So it was perfect for using Docky. But with Unity 2D the Unity settings don't have any effect. How can I completely hide the start-panel and just have it shown when pressing the windows-key? With the following: dconf write /com/canonical/unity-2d/launcher/hide-mode 1 dconf write /com/canonical/unity-2d/launcher/use-strut false it still opens the bar when going with my mouse to the left.

    I need to install the library iodbc (depends on libodbc2) in my Quantal machine. Yet there is creepy dependency problem. This was replaced somehow by unixodbc which I don't have, installed. Here is what I get when I try to install : sudo apt-get install libiodbc2-dev Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.

After this operation, 126 MB disk space will be freed. Do you want to continue [Y/n]? Other info: Why do the "iodbc" and "libmyodbc" packages conflict with each other? The root problem is that I need to use a new feature introduced in the latest MySQL Workbench builds (DB Migration) which uses odbc for that matter. Here is what Mysql doc says about it : Linux The Migration Wizard uses iODBC as a driver manager for all of its ODBC connections in Linux. This may give you some troubles because most Linux distributions provide ODBC drivers compiled against unixODBC. This is another driver manager not supported by MySQL Workbench so you won’t be able to use those drivers unless you compile them against iODBC. Here’s what you should do. Make sure that you have iODBC installed. If you are using Debian, Ubuntu or another Debian based distro, type this command in your terminal: $ sudo apt-get install iodbc libiodbc2-dev libpq-dev libssl-dev For RPM based distros (RedHat, Fedora, etc.) type this command instead of the previous one: $ sudo yum install iodbc iodbc-dev libpqxx-devel openssl-devel Now we need to install the PostgreSQL ODBC drivers. Download the psqlODBC source tarball from here. Use the latest version available for download. As of this writing the latest version corresponds to the file psqlodbc-09.01.0200.tar.gz. Extract this tarball to a directory in your hard drive and open a terminal and cd into that directory. Type this in the terminal window: $ ./configure --with-iodbc --enable-pthreads $ make $ sudo make install Verify that you have the file psqlodbcw.so in the /usr/local/lib directory. This package seems to pose the problem probably: dpkg -s odbcinst1debian2 Package: odbcinst1debian2 Status: install ok installed Priority: optional Section: libs Installed-Size: 241 Maintainer: Ubuntu Developers <[email protected]> Architecture: amd64 Multi-Arch: same Source: unixodbc Version: 2.2.14p2-5ubuntu4 Replaces: unixodbc (<< 2.1.1-2) Depends: libc6 (>= 2.14), libltdl7 (>= 2.4.2), odbcinst Pre-Depends: multiarch-support Breaks: libiodbc2, libmyodbc (<< 5.1.6-2), odbc-postgresql (<< 1:09.00.0310-1.1), tdsodbc (<< 0.82-8) Conflicts: odbcinst1, odbcinst1debian1 Description: Support library for accessing odbc ini files This package contains the libodbcinst library from unixodbc, a library used by ODBC drivers for reading their configuration settings from /etc/odbc.ini and ~/.odbc.ini. .

  • Exporting the frames in a Flash CS5.5 animation and possibly creating the spritesheet

    - by Adam Smith
    Some time ago, I asked a question here to know what would be the best way to create animations when making an Android game and I got great answers. I did what people told me there by exporting each frame from a Flash animation manually and creating the spritesheet also manually and it was very tedious. Now, I changed project and this one is going to contain a lot more animations and I feel like there has to be a better way to to export each frame individually and possibly create my spritesheets in an automated manner. My designer is using Flash CS5.5 and I was wondering if all of this was possible, as I can't find an option or code examples on how to save each frame individually. If this is not possible using Flash, please recommend me another program that can be used to create animations without having to create each frame on its own. I'd rather keep Flash as my designer knows how to use it and it's giving great results.

  • Dynamically switching the theme in Orchard

    - by Bertrand Le Roy
    It may sound a little puzzling at first, but in Orchard CMS, more than one theme can be active at any given time. The reason for that is that we have an extensibility point that allows a module (or a theme) to participate in the choice of the theme to use, for each request. The motivation for building the theme engine this way was to enable developers to switch themes based on arbitrary criteria, such as user preferences or the user agent (if you want to serve a mobile theme for phones for example). The choice is made between the active themes, which is why there is a difference between the default theme and the active themes. In order to have a say in the choice of the theme, all you have to do is implement IThemeSelector. That interface is quite simple as it only has one method, GetTheme, that takes the current RequestContext and returns a ThemeSelectorResult or null if the implementation of the interface does not want to participate in the current request (we'll see an example in a moment). ThemeSelectorResult itself is just a ThemeName string property and an integer Priority. We're using a priority so that an arbitrary number of implementations of IThemeSelector can contribute to the choice of a theme. If you look for existing implementations of the interface in Orchard, you'll find four: AdminThemeSelector: selects the TheAdmin theme with a very high priority (100) if the current request is for a page that is part of the admin. Otherwise, null is returned, which enables other implementations to choose the theme. PreviewThemeSelector: selects the preview theme if there is one, with a high priority (90), and null otherwise. This enables administrators to view the site under a different theme while everybody else continues to see the current default theme. SiteThemeSelector: this is the implementation that is doing what you expect most of the time, which is to get the current theme from site settings and set it with a priority of –5. SafeModeThemeSelector: this is the fallback implementation, which should almost never win. It sets the theme as the safe mode theme, which has no style and just uses the default templates for everything. The priority is very low (-100). While this extensibility mechanism is great to have, I wanted to bring that level of choice into the hands of the site administrator rather than just developers. In order to achieve that, I built the Vandelay Theme Picker module. The module provides administration UI to create rules for theme selection. It provides its own extensibility point (the IThemeSelectionRule interface) and one implementation of a rule: UserAgentThemeSelectorRule. This rule gets the current user agent from the context and tries to match it with a regular expression that the administrator can configure in the admin UI. You can for example configure a rule with a regular expression that matches IE6 and serve a different subtheme where the stylesheet has been tweaked for such an antique browser. Another possible configuration is to detect mobile devices from their agent string and serve the mobile theme. All those operations can be done with this module entirely from the admin UI, without writing a line of code. The module also offers the administrator the opportunity to inject a link into the front-end in a specific zone and with a specific position that enables the user to switch to the default theme if he wishes to. This is especially useful for sites that use a mobile theme but still want to allow users to use the full desktop site. While the module is nice and flexible, it may be overkill. On my own personal blog, I have only two active themes: the desktop theme and the mobile theme. I'm fine with going into code to change the criteria on which to switch the theme, so I'm not using my own Theme Picker module. Instead, I made the mobile theme a theme with code (in other words there is a csproj file in the theme). The project includes a single C# file, my MobileThemeSelector for which the code is the following: public class MobileThemeSelector : IThemeSelector { private static readonly Regex _Msie678 = new Regex(@"^Mozilla\/4\.0 \(compatible; MSIE [678]" + @"\.0; Windows NT \d\.\d(.*)\)$", RegexOptions.IgnoreCase); private ThemeSelectorResult _requestCache; private bool _requestCached; public ThemeSelectorResult GetTheme(RequestContext context) { if (_requestCached) return _requestCache; _requestCached = true; var userAgent = context.HttpContext.Request.UserAgent; if (userAgent.IndexOf("phone", StringComparison.OrdinalIgnoreCase) != -1 || _Msie678.IsMatch(userAgent) || userAgent.IndexOf("windows live writer", StringComparison.OrdinalIgnoreCase) != -1) { _requestCache = new ThemeSelectorResult { Priority = 10, ThemeName = "VuLuMobile" }; } return _requestCache; } } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } The theme selector selects the current theme for Internet Explorer versions 6 to 8, for phones, and for Windows Live Writer (so that the theme that is used when I write posts is as simple as possible). What's interesting here is that it's the theme that selects itself here, based on its own criteria. This should give you a good panorama of what's possible in terms of dynamic theme selection in Orchard. I hope you find some fun uses for it. As usual, I can't wait to see what you're going to come up with…

  • How to achieve highly accurate car physics such as Liveforspeed?

    - by Kim Jong Woo
    Liveforspeed is a racing simulator, there is amazing amount of realistic physics. for example, tires get warm, tire actually deforms when you turn corners. You need to play this game with a mouse at the minimum because it almost drives like the real thing. Anyhow, how does one achieve that level of physics simulation? Are there off-the-shelf solutions out there? If not, how does one start with simulating real world physics as close as possible. I would love to be able to work on an opensource car physics focused game. Imagine, more passionate developers, it could keep things going.

  • The Threats are Outside the Risks are Inside

    - by Naresh Persaud
    In the past few years we have seen the threats against the enterprise increase dramatically. The number of attacks originating externally have outpaced the number of attacks driven by insiders. During the CSO Summit at Open World, Sonny Singh examined the phenomenon and shared Oracle's security story. While the threats are largely external, the risks are largely inside. Criminals are going after our sensitive customer data. In some cases the attacks are advanced. In most cases the attacks are very simple. Taking a security inside out approach can provide a cost effective way to secure an organization's most valuable assets. &amp;amp;amp;lt;/span&amp;amp;amp;gt;border-width:1px 1px 0;margin-bottom:5px&amp;amp;amp;quot; allowfullscreen=&amp;amp;amp;quot;&amp;amp;amp;quot;&amp;amp;amp;gt; Cso oow12-summit-sonny-sing hv4 from OracleIDM
