  • WolframAlpha Can Now Do In-depth Analysis of Your Facebook Account

    - by Jason Fitzpatrick
    If you’re a big fan of WolframAlpha’s ability to crunch the numbers on just about anything–and we certainly are–you’ll likely be just as delighted as we were to watch it massage the data from your Facebook account. Find out your most liked, discussed, and shared posts, see your Facebook habits, and other neat trends. I unleashed it on my account this morning, not sure what to expect from the results. Within the results tabulation WolframAlpha provided me with all sorts of neat data break downs. I now know exactly how many days it is to my next birthday, the composition of my aggregate posting habits (how many posts are status updates, links, or photos), the time of day when I do the most posting (and what the composition of those posts is), and my average post length. I also know my most liked post and my most commented on post. It will even crunch the numbers on your network of friends (60.6% of my friends are married, for example). By far one of the more interesting data analysis it does on the friendship data, however, is organizing all your friends into relationship clusters so you can see who in your Facebook network is friends with other people in your Facebook network. The service from WolframAlpha is free: simply visit the WolframAlpha search portal and type in “Facebook report” to start the process. You’ll be prompted to create a WolframAlpha account if you don’t have one and to authorize the WolframAlpha Facebook app to access your data. Your Facebook data is cached to your WolframAlpha account for one hour in order to crunch the numbers and display the results.

  • TechEd 2010 Day Two – No SQL Server in Sight

    - by BuckWoody
    Today I worked the booth at TechEd 2010, manning the new “Surface” computer, which is just the coolest object on the planet. After that I didn’t attend a single SQL Server session – instead I’ve been frequenting SharePoint, Microsoft Office, and even the High-Performance Computing sessions. The reason is that I get really high quality SQL Server presentations at PASS, SQL Saturdays, and online from Microsoft and other vendors. While there are SQL Server sessions here (after all, I’m giving one of them!) I tend to try and see things that I don’t normally get to learn about. And the cross-pollination between those technologies and mine is fantastic.     I’ve even managed to go to an Entity Framework presentation for the developers. I actually have (a little) more respect for that technology – and I’ve modified my presentation to encompass more of that information. So whenever you have the chance, take a walk outside your comfort zone. Even at PASS and SQL Saturdays (and certainly online) you can investigate technologies other than the ones you know best.  Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Watch the Geminid Meteors Tonight

    - by Jason Fitzpatrick
    Tonight is the peak of the Geminid Meteor shower, if you don’t mind braving the cold and have a spot relatively free from light pollution to stretch out in you’ll be able to enjoy one of the more brilliant and busy meteor showers of the year. Sky and Telescope magazine reports on the Geminid Meteor shower: If it’s clear late Thursday night, December 13th, 2012, keep a lookout high overhead for the shooting stars of the Geminid meteor shower. The Geminids are usually one of the two best meteor showers of the year, often beating out the Perseids of August. And this year there’s no moonlight to interfere. Under a clear, dark sky, you may see at least one Geminid per minute on average from roughly 10 p.m. Thursday until dawn Friday morning. If you live under the artificial skyglow of light pollution your numbers will be less, but the brightest meteors will still shine through. Hit up the link below to read the full article and learn more about the Geminid Meteor shower.

  • DropSpace Syncs Android Files to Dropbox

    - by ETC
    DropSpace is a free Android application that fixes the primary issue that plagues the official Dropbox app for Android–the lack of true file synchronization. Grab a copy of DropSpace and start enjoying true file syncing on the go. The official Dropbox app is limited to grabbing files from your Dropbox account or pushing files from your phone to your Dropbox account. Actual file synchronization, this manual push/pull model aside, is nowhere to be found. DropSpace fills that gap by enabling file synchronization between your SD card directories and your Dropbox directories. It’s packed with handy features including restricting file syncing to Wi-Fi connection only (great if you don’t want to chew up your very limited data plan) as well as numerous toggles for various settings like whether it should delete remote files if the local file is deleted, how often it should run the sync service, and more. Hit up the link below to grab a copy and take it for a test drive. DropSpace is free and works wherever Android does; Dropbox account required.

  • Why unhandled exceptions are useful

    - by Simon Cooper
    It’s the bane of most programmers’ lives – an unhandled exception causes your application or webapp to crash, an ugly dialog gets displayed to the user, and they come complaining to you. Then, somehow, you need to figure out what went wrong. Hopefully, you’ve got a log file, or some other way of reporting unhandled exceptions (obligatory employer plug: SmartAssembly reports an application’s unhandled exceptions straight to you, along with the entire state of the stack and variables at that point). If not, you have to try and replicate it yourself, or do some psychic debugging to try and figure out what’s wrong. However, it’s good that the program crashed. Or, more precisely, it is correct behaviour. An unhandled exception in your application means that, somewhere in your code, there is an assumption that you made that is actually invalid. Coding assumptions Let me explain a bit more. Every method, every line of code you write, depends on implicit assumptions that you have made. Take this following simple method, that copies a collection to an array and includes an item if it isn’t in the collection already, using a supplied IEqualityComparer: public static T[] ToArrayWithItem( ICollection<T> coll, T obj, IEqualityComparer<T> comparer) { // check if the object is in collection already // using the supplied comparer foreach (var item in coll) { if (comparer.Equals(item, obj)) { // it's in the collection already // simply copy the collection to an array // and return it T[] array = new T[coll.Count]; coll.CopyTo(array, 0); return array; } } // not in the collection // copy coll to an array, and add obj to it // then return it T[] array = new T[coll.Count+1]; coll.CopyTo(array, 0); array[array.Length-1] = obj; return array; } What’s all the assumptions made by this fairly simple bit of code? coll is never null comparer is never null coll.CopyTo(array, 0) will copy all the items in the collection into the array, in the order defined for the collection, starting at the first item in the array. The enumerator for coll returns all the items in the collection, in the order defined for the collection comparer.Equals returns true if the items are equal (for whatever definition of ‘equal’ the comparer uses), false otherwise comparer.Equals, coll.CopyTo, and the coll enumerator will never throw an exception or hang for any possible input and any possible values of T coll will have less than 4 billion items in it (this is a built-in limit of the CLR) array won’t be more than 2GB, both on 32 and 64-bit systems, for any possible values of T (again, a limit of the CLR) There are no threads that will modify coll while this method is running and, more esoterically: The C# compiler will compile this code to IL according to the C# specification The CLR and JIT compiler will produce machine code to execute the IL on the user’s computer The computer will execute the machine code correctly That’s a lot of assumptions. Now, it could be that all these assumptions are valid for the situations this method is called. But if this does crash out with an exception, or crash later on, then that shows one of the assumptions has been invalidated somehow. An unhandled exception shows that your code is running in a situation which you did not anticipate, and there is something about how your code runs that you do not understand. Debugging the problem is the process of learning more about the new situation and how your code interacts with it. When you understand the problem, the solution is (usually) obvious. The solution may be a one-line fix, the rewrite of a method or class, or a large-scale refactoring of the codebase, but whatever it is, the fix for the crash will incorporate the new information you’ve gained about your own code, along with the modified assumptions. When code is running with an assumption or invariant it depended on broken, then the result is ‘undefined behaviour’. Anything can happen, up to and including formatting the entire disk or making the user’s computer sentient and start doing a good impression of Skynet. You might think that those can’t happen, but at Halting problem levels of generality, as soon as an assumption the code depended on is broken, the program can do anything. That is why it’s important to fail-fast and stop the program as soon as an invariant is broken, to minimise the damage that is done. What does this mean in practice? To start with, document and check your assumptions. As with most things, there is a level of judgement required. How you check and document your assumptions depends on how the code is used (that’s some more assumptions you’ve made), how likely it is a method will be passed invalid arguments or called in an invalid state, how likely it is the assumptions will be broken, how expensive it is to check the assumptions, and how bad things are likely to get if the assumptions are broken. Now, some assumptions you can assume unless proven otherwise. You can safely assume the C# compiler, CLR, and computer all run the method correctly, unless you have evidence of a compiler, CLR or processor bug. You can also assume that interface implementations work the way you expect them to; implementing an interface is more than simply declaring methods with certain signatures in your type. The behaviour of those methods, and how they work, is part of the interface contract as well. For example, for members of a public API, it is very important to document your assumptions and check your state before running the bulk of the method, throwing ArgumentException, ArgumentNullException, InvalidOperationException, or another exception type as appropriate if the input or state is wrong. For internal and private methods, it is less important. If a private method expects collection items in a certain order, then you don’t necessarily need to explicitly check it in code, but you can add comments or documentation specifying what state you expect the collection to be in at a certain point. That way, anyone debugging your code can immediately see what’s wrong if this does ever become an issue. You can also use DEBUG preprocessor blocks and Debug.Assert to document and check your assumptions without incurring a performance hit in release builds. On my coding soapbox… A few pet peeves of mine around assumptions. Firstly, catch-all try blocks: try { ... } catch { } A catch-all hides exceptions generated by broken assumptions, and lets the program carry on in an unknown state. Later, an exception is likely to be generated due to further broken assumptions due to the unknown state, causing difficulties when debugging as the catch-all has hidden the original problem. It’s much better to let the program crash straight away, so you know where the problem is. You should only use a catch-all if you are sure that any exception generated in the try block is safe to ignore. That’s a pretty big ask! Secondly, using as when you should be casting. Doing this: (obj as IFoo).Method(); or this: IFoo foo = obj as IFoo; ... foo.Method(); when you should be doing this: ((IFoo)obj).Method(); or this: IFoo foo = (IFoo)obj; ... foo.Method(); There’s an assumption here that obj will always implement IFoo. If it doesn’t, then by using as instead of a cast you’ve turned an obvious InvalidCastException at the point of the cast that will probably tell you what type obj actually is, into a non-obvious NullReferenceException at some later point that gives you no information at all. If you believe obj is always an IFoo, then say so in code! Let it fail-fast if not, then it’s far easier to figure out what’s wrong. Thirdly, document your assumptions. If an algorithm depends on a non-trivial relationship between several objects or variables, then say so. A single-line comment will do. Don’t leave it up to whoever’s debugging your code after you to figure it out. Conclusion It’s better to crash out and fail-fast when an assumption is broken. If it doesn’t, then there’s likely to be further crashes along the way that hide the original problem. Or, even worse, your program will be running in an undefined state, where anything can happen. Unhandled exceptions aren’t good per-se, but they give you some very useful information about your code that you didn’t know before. And that can only be a good thing.

  • Do I need social networks to be an expert developer? [closed]

    - by Gerald Blizzy
    This question may sound odd, but do I need twitter, facebook and google+ if I am a web-developer? I see many expert developers nowadays using it in working order. It seems like it's harder to stay in touch with customers, co-workers and potential customers if you don' use social networks. Am I right? Reason why I ask is that I am totally not a facebook/twitter person, I find it boring and annoying. I understand that linkedin is usefull for career, but what about twitter and facebook? Are they needed for web-developer career? What I am trying to ask is if I only use linkedin, own portfolio website, google talks, gmail and something like github, would I actually miss anything professionally/job-wise? My thoughts are that I can just have my portfolio website where I list all my projects aswell as contacts page with my google talks/gmail account. It can suit both fulltime job, freelance and own projects. So this way email and google talks is just enough. Am I right or not? Thanks in advance!

  • What the Hekaton?

    - by Tony Davis
    Hekaton, the power behind SQL Server 2014′s In-Memory OLTP technology, is intended to make data operations run orders of magnitude faster on SQL Server. This works its magic partly by serving database workloads entirely from main memory, using memory-optimized table structures. It replaces the relational engine’s standard locking model with an optimistic concurrency model based on time-stamped row versions. Deeper down the Hekaton engine uses new, ‘latch free’ data structures. So far, so good, but performance improvements on this scale require a compromise, and the compromise is that these aren’t tables as we understand them. For the database developer, these differences are painful because they involve sacrificing some very important bits of the relational model. Most importantly, Hekaton tables don’t currently support FOREIGN KEY constraints or CHECK constraints, and you can’t put the checks in triggers because there aren’t any DML triggers either. Constraints allow a relational designer to enforce relational integrity and data integrity. Without them, of course, ‘bad data’ can get into our Hekaton tables. There is no easy way of preventing it. For several classes of database and data, this is a show-stopper. One may regard all these restrictions regretfully, seeing limited opportunity to try out Hekaton with current databases, but perhaps there is also a sudden glow of recognition. Isn’t this how we all originally imagined table variables were going to be, back in SQL 2005? And they have much the same restrictions. Maybe, instead of pretending that a currently-designed database can be ‘Hekatonized’ with a few mouse clicks, we should redesign databases for SQL 2014 to replace table variables with Hekaton tables, exploiting this technology for fast intermediate processing, and for the most part forget, for now, the idea of trying to convert our base relational tables into Hekaton tables. Few database developers would be averse to having their working tables running an order of magnitude faster, as long as it didn’t compromise the integrity of the data in the base tables.

  • Oracle Java Olympics Between Russia, Ukraine, Belarus, Ukraine and Kazakhstan

    - by Tori Wieldt
    Last month, 151 universities in 11 locations (Saint-Petersburg, Moscow, Donetsk, Tomsk, Odessa, Rostov-on-Don, Ekaterinburg, Khabarovsk, Almaty, Kiev, and Samara) competed in the second round of the Oracle Java Olympics. For two weeks in February, the best university students from Russia, Ukraine, Belarus, Ukraine and Kazakhstan were invited to compete with each other and prove just how good they are in Java programming.  A team of engineers from Oracle Development center in Saint-Petersburg prepared the set of problems to solve during the competition. To win, participants needed to show deep knowledge of Java technologies from Classloader and NIO to Reflection and JavaDB. Students in each location had a PC with Oracle JDK 1.7u2 and Netbeans 7.1.  As a testing system, the organizers used the open source software Ejudge (with several tweaks specifically for the competition).  Participants submitted their solutions to the remote server where they were tested by prepared test harnesses.

  • Microsoft Tag Tagged Me

    - by Brian Schroer
    I got EXTREMELY lucky last week and won an HP Mini 311 notebook from a Microsoft Tag Twitter contest. I did my required tweet to enter last Tuesday, and one hour later received notification that I had won the weekly drawing. Apparently you can tweet up to 500 times (I pity the followers of those who do that), so it was really lucky that I won, and I sympathize with those who had been really trying. If you would like to try your luck, there are seven weekly prizes left, and you can find out about the contest here: http://tag.microsoft.com/ttcontest.aspx For a free PC, I thought it was the least I could do to find out what Microsoft Tag is. I was vaguely aware of those pastel-y triangle-y square things that look like someone put one of Don Johnson’s Miami Vice outfits through a shredder, and knew that the company I work for (one of the world’s largest consumer products companies) was looking into putting them on our products, packaging and advertising, but didn’t know much more about the technology. I thought they were just an improvement over bar codes, and would be used in retail store scanners, but I was mistaken. These tags are meant to be scanned by consumers using their mobile phones, to get instant access to information, websites, reviews, etc. Scanning a tag can open a web page, import a contact card, or dial a phone number, play a video… Tag reader software can be installed on Windows Mobile, iPhone, Symbian, Blackberry, Android, J2ME, and other phones (and I suspect that it will be available for Windows Phone 7 also :). There are built-in tracking, metrics and analysis tools, to help companies using Tag make decisions about their marketing expenditures. (And they don’t have to look Miami Vice-y – They can be customized to reflect the personality of the person or a brand.) Looks like interesting stuff. You can find out more at http://tag.microsoft.com.

  • HTG Explains: Which Linux File System Should You Choose?

    - by Justin Garrison
    File systems are one of the layers beneath your operating system that you don’t think about—unless you’re faced with the plethora of options in Linux. Here’s how to make an educated decision on which file system to use. The landscape of the Linux file system support is drastically different from Windows and OS X. In Windows and OS X you can find software that will add support for non-standard file systems, but both operating systems can only be installed on their native file system and third party support is added after the fact. Linux on the other hand has a vast array of supported file systems built into the kernel. But how are you supposed to know which file system to pick when installing? We will take a look at some of the most popular choices available and give you use cases to consider—the choice is ultimately up to you based on your needs.

  • Inside the DLR – Invoking methods

    - by Simon Cooper
    So, we’ve looked at how a dynamic call is represented in a compiled assembly, and how the dynamic lookup is performed at runtime. The last piece of the puzzle is how the resolved method gets invoked, and that is the subject of this post. Invoking methods As discussed in my previous posts, doing a full lookup and bind at runtime each and every single time the callsite gets invoked would be far too slow to be usable. The results obtained from the callsite binder must to be cached, along with a series of conditions to determine whether the cached result can be reused. So, firstly, how are the conditions represented? These conditions can be anything; they are determined entirely by the semantics of the language the binder is representing. The binder has to be able to return arbitary code that is then executed to determine whether the conditions apply or not. Fortunately, .NET 4 has a neat way of representing arbitary code that can be easily combined with other code – expression trees. All the callsite binder has to return is an expression (called a ‘restriction’) that evaluates to a boolean, returning true when the restriction passes (indicating the corresponding method invocation can be used) and false when it does’t. If the bind result is also represented in an expression tree, these can be combined easily like so: if ([restriction is true]) { [invoke cached method] } Take my example from my previous post: public class ClassA { public static void TestDynamic() { CallDynamic(new ClassA(), 10); CallDynamic(new ClassA(), "foo"); } public static void CallDynamic(dynamic d, object o) { d.Method(o); } public void Method(int i) {} public void Method(string s) {} } When the Method(int) method is first bound, along with an expression representing the result of the bind lookup, the C# binder will return the restrictions under which that bind can be reused. In this case, it can be reused if the types of the parameters are the same: if (thisArg.GetType() == typeof(ClassA) && arg1.GetType() == typeof(int)) { thisClassA.Method(i); } Caching callsite results So, now, it’s up to the callsite to link these expressions returned from the binder together in such a way that it can determine which one from the many it has cached it should use. This caching logic is all located in the System.Dynamic.UpdateDelegates class. It’ll help if you’ve got this type open in a decompiler to have a look yourself. For each callsite, there are 3 layers of caching involved: The last method invoked on the callsite. All methods that have ever been invoked on the callsite. All methods that have ever been invoked on any callsite of the same type. We’ll cover each of these layers in order Level 1 cache: the last method called on the callsite When a CallSite<T> object is first instantiated, the Target delegate field (containing the delegate that is called when the callsite is invoked) is set to one of the UpdateAndExecute generic methods in UpdateDelegates, corresponding to the number of parameters to the callsite, and the existance of any return value. These methods contain most of the caching, invoke, and binding logic for the callsite. The first time this method is invoked, the UpdateAndExecute method finds there aren’t any entries in the caches to reuse, and invokes the binder to resolve a new method. Once the callsite has the result from the binder, along with any restrictions, it stitches some extra expressions in, and replaces the Target field in the callsite with a compiled expression tree similar to this (in this example I’m assuming there’s no return value): if ([restriction is true]) { [invoke cached method] return; } if (callSite._match) { _match = false; return; } else { UpdateAndExecute(callSite, arg0, arg1, ...); } Woah. What’s going on here? Well, this resulting expression tree is actually the first level of caching. The Target field in the callsite, which contains the delegate to call when the callsite is invoked, is set to the above code compiled from the expression tree into IL, and then into native code by the JIT. This code checks whether the restrictions of the last method that was invoked on the callsite (the ‘primary’ method) match, and if so, executes that method straight away. This means that, the next time the callsite is invoked, the first code that executes is the restriction check, executing as native code! This makes this restriction check on the primary cached delegate very fast. But what if the restrictions don’t match? In that case, the second part of the stitched expression tree is executed. What this section should be doing is calling back into the UpdateAndExecute method again to resolve a new method. But it’s slightly more complicated than that. To understand why, we need to understand the second and third level caches. Level 2 cache: all methods that have ever been invoked on the callsite When a binder has returned the result of a lookup, as well as updating the Target field with a compiled expression tree, stitched together as above, the callsite puts the same compiled expression tree in an internal list of delegates, called the rules list. This list acts as the level 2 cache. Why use the same delegate? Stitching together expression trees is an expensive operation. You don’t want to do it every time the callsite is invoked. Ideally, you would create one expression tree from the binder’s result, compile it, and then use the resulting delegate everywhere in the callsite. But, if the same delegate is used to invoke the callsite in the first place, and in the caches, that means each delegate needs two modes of operation. An ‘invoke’ mode, for when the delegate is set as the value of the Target field, and a ‘match’ mode, used when UpdateAndExecute is searching for a method in the callsite’s cache. Only in the invoke mode would the delegate call back into UpdateAndExecute. In match mode, it would simply return without doing anything. This mode is controlled by the _match field in CallSite<T>. The first time the callsite is invoked, _match is false, and so the Target delegate is called in invoke mode. Then, if the initial restriction check fails, the Target delegate calls back into UpdateAndExecute. This method sets _match to true, then calls all the cached delegates in the rules list in match mode to try and find one that passes its restrictions, and invokes it. However, there needs to be some way for each cached delegate to inform UpdateAndExecute whether it passed its restrictions or not. To do this, as you can see above, it simply re-uses _match, and sets it to false if it did not pass the restrictions. This allows the code within each UpdateAndExecute method to check for cache matches like so: foreach (T cachedDelegate in Rules) { callSite._match = true; cachedDelegate(); // sets _match to false if restrictions do not pass if (callSite._match) { // passed restrictions, and the cached method was invoked // set this delegate as the primary target to invoke next time callSite.Target = cachedDelegate; return; } // no luck, try the next one... } Level 3 cache: all methods that have ever been invoked on any callsite with the same signature The reason for this cache should be clear – if a method has been invoked through a callsite in one place, then it is likely to be invoked on other callsites in the codebase with the same signature. Rather than living in the callsite, the ‘global’ cache for callsite delegates lives in the CallSiteBinder class, in the Cache field. This is a dictionary, typed on the callsite delegate signature, providing a RuleCache<T> instance for each delegate signature. This is accessed in the same way as the level 2 callsite cache, by the UpdateAndExecute methods. When a method is matched in the global cache, it is copied into the callsite and Target cache before being executed. Putting it all together So, how does this all fit together? Like so (I’ve omitted some implementation & performance details): That, in essence, is how the DLR performs its dynamic calls nearly as fast as statically compiled IL code. Extensive use of expression trees, compiled to IL and then into native code. Multiple levels of caching, the first of which executes immediately when the dynamic callsite is invoked. And a clever re-use of compiled expression trees that can be used in completely different contexts without being recompiled. All in all, a very fast and very clever reflection caching mechanism.

  • Mod a Swing Arm Lamp into an Adjustable Camera Stand

    - by Jason Fitzpatrick
    If you’re looking for a simple way to get a bird’s eye view to record your DIY projects or other table-based activities like gaming or tinkering, this simple modification to a swing-arm lamp offers a highly flexible camera mount on the cheap. IKEAHacker reader Stef needed an adjustable arm for his iPhone camera so he could record in a top-down-view for some drawing tutorials he was working on. Rather than shell out big bucks for a custom boom arm, he scrounged up a swing arm lamp with a broken shade in the as-is bin at his local IKEA. To mount the iPhone he simply attached a car mount for the iPhone to the swing arm and called it good.

  • Byte Size Tips: How to Show Google / Gmail Contacts in the OS X Contacts App

    - by The Geek
    The Contacts app on OS X isn’t very interesting, but if you can use it to display your Gmail contacts, it’ll get a little bit better. Luckily it’s pretty easy to add your Google / Gmail contacts, but you’ll have to click the mouse a few times and maybe poke at the old keyboard once or twice to type in your email address and password. It’s worth noting that if you set up Gmail in the Mail app you shouldn’t have to do this. Since we prefer Gmail in a browser, that’s why we’re writing this. Or just because we’re procrastinating the book editing that we’re supposed to be doing. Don’t judge. Start by opening the Preferences for the Contacts app by heading up to the Menu bar. Go to Accounts and then click the + sign to add a new one. Choose CardDAV for the account type, use your Gmail username and password, and put google.com as the server address. If you are using two-factor authentication, you’ll need to create a specific password for this account.

  • GMail:Want To Embed Picture In Your Mail? Drag and Drop It

    - by Gopinath
    GMail rolled out a nice & useful feature that makes embedding images into emails very easy. Now you can drag and drop an image on the text area of your GMail compose interface to embed it. From now onwards to insert an Image I’ll go with drag & drop instead of using Insert Image option that allows us to choose an image by navigating through the folders. Wait, This Works Only For Google Chrome Users! This feature work only on Google Chrome browser. At least for now. Firefox, IE users have to wait. Google has promised to provide this feature in all other major browsers, but it’s going to take some time. The other browsers don’t have the ability to support this feature or Google trying to promote Chrome by releasing Chrome only features in their popular products? You decide. You can read more details about this in the official GMail blog post. Join us on Facebook to read all our stories right inside your Facebook news feed.

  • How the OS Makes the Database Scream

    - by rickramsey
    source Few things are as satisfying as a screaming burnout. When Oracle Database engineers team up with Solaris engineers, they do a lot of them. Here are a few of the reasons why. Article: How the OS Makes the Database Fast - Oracle Solaris For applications that rely on Oracle Database, a high-performance operating system translates into faster transactions, better scalability to support more users, and the ability to support larger capacity databases. When deployed in virtualized environments, multiple Oracle Database servers can be consolidated on the same physical server. Ginny Henningsen describes what Oracle Solaris does to make the Oracle database run faster. Interview: Why Is The OS Still Relevant? In a world of increasing virtualization and growing interest in cloud services, why is the OS still relevant? Michael Palmeter, senior director of Oracle Solaris, explains why it's not only relevant, but essential for data centers that care about performance. Interview: An Engineer's Perspective: Why the OS Is Still Relevant Sysadmins are handling hundreds or perhaps thousands of VM's. What is it about Solaris that makes it such a good platform for managing those VM's? Liane Praza, senior engineer in the Solaris core engineering group provides an engineer's perspective. Interview in the Lab: How to Get the Performance Promised by Oracle's T5 SPARC Chips If you want your applications to run on the new SPARC T5/M5 chips, how do you make sure they use all that new performance? Don Kretsch, Senior Director of Engineering, explains. Interview: Why Oracle Database Engineering Uses Oracle Solaris Studio The design priorities for Oracle Solaris Studio are performance, observability, and productivity. Why this is good for ISV's and developers, and why it's so important to the Oracle database engineering team.

  • Static DataTable or DataSet in a class - bad idea?

    - by Superbest
    I have several instances of a class. Each instance stores data in a common database. So, I thought "I'll make the DataTable table field static, that way every instance can just add/modify rows to its own table field, but all the data will actually be in one place!" However, apparently it's a bad idea to do use static fields, especially if it's databases: Don't Use "Static" in C#? Is this a bad idea? Will I run into problems later on if I use it? This is a small project so I can accept no testing as a compromise if that is the only drawback. The benefit of using a static database is that there can be many objects of type MyClass, but only one table they all talk to, so a static field seems to be an implementation of exactly this, while keeping syntax concise. I don't see why I shouldn't use a static field (although I wouldn't really know) but if I had to, the best alternative I can think of is creating one DataTable, and passing a reference to it when creating each instance of MyClass, perhaps as a constructor parameter. But is this really an improvement? It seems less intuitive than a static field.
