  • Turnkey with LightSwitch

    - by Laila
    Microsoft has long wanted to find a replacement for Microsoft Access. The best attempt yet, which is due out in, or before, September is Visual Studio LightSwitch, with which it is said to be as 'easy as flipping a switch' to use Silverlight to create simple form-driven business applications. It is easy to get confused by the various initiatives from Microsoft. No, this isn't WebMatrix. There is no 'Razor', for this isn't meant for cute little ecommerce sites, but is designed to build simple database-applications of the card-box type. It is more clearly a .NET-based solution to the problem that every business seems to suffer from; the plethora of Access-based, and Excel-based 'private' and departmental database-applications. These are a nightmare for any IT department since they are often 'stealth' applications built by the business in the teeth of opposition from the IT Department zealots. As they are undocumented, it is scarily easy to bring a whole department into disarray by decommissioning a PC tucked under a desk somewhere. With LightSwitch, it is easy to re-write such applications in a standard, maintainable, way, using a SQL Server database, deployed somewhere reasonably safe such as Azure. Even Sharepoint or Windows Communication Foundation can be used as data sources. Oracle's ApEx has taken off remarkably well, and has shaken the perception that, for the business user, Oracle must remain a mystic force accessible only to the priests and acolytes. Microsoft, by comparison had only Access, which was first released in 1992, the year of the Madonna conical bustier. It looks just as dated. Microsoft badly needed an entirely new solution to the same business requirement that led to Access's and Foxpro's long-time popularity, but which had the same allure as ApEx. LightSwitch is sound in its ideas, and comfortingly conventional in its architecture. By giving an easy access to SQL Server databases, and providing a 'thumb and blanket' migration path to Access-heads, LightSwitch seems likely to offer a simple way of pulling more Microsoft users into the .NET community. If Microsoft puts its weight behind it, then it will give some glimmer of hope to the many Silverlight developers that Microsoft is capable of seeing through its .NET revolution.

  • What are the problems with a relatively large common library?

    - by Sam Pearson
    As long as the code in the base library is as loosely coupled as splitting it up into separate libraries, what's the problem? In general, having a lot of assemblies composing a .NET solution is painful. Plus, when code in one solution needs to be shared, it can just be added to the common library, rather than deciding which common library it should be added to or creating yet another library. edit: the question comes to me after using Smalltalk for a bit, where all the code is available to use, all the time.

  • SQL SERVER – Fix: Error: 147 An aggregate may not appear in the WHERE clause unless it is in a subquery contained in a HAVING clause or a select list, and the column being aggregated is an outer reference

    - by pinaldave
    Everybody was beginner once and I always like to get involved in the questions from beginners. There is a big difference between the question from beginner and question from advanced user. I have noticed that if an advanced user gets an error, they usually need just a small hint to resolve the problem. However, when a beginner gets error he sometimes sits on the error for a long time as he/she has no idea about how to solve the problem as well have no idea regarding what is the capability of the product. I recently received a very novice level question. When I received the problem I quickly see how the user was stuck. When I replied him with the solution, he wrote a long email explaining how he was not able to solve the problem. He thanked multiple times in the email. This whole thing inspired me to write this quick blog post. I have modified the user’s question to match the code with AdventureWorks as well simplified so it contains the core content which I wanted to discuss. Problem Statement: Find all the details of SalesOrderHeaders for the latest ShipDate. He comes up with following T-SQL Query: SELECT * FROM [Sales].[SalesOrderHeader] WHERE ShipDate = MAX(ShipDate) GO When he executed above script it gave him following error: Msg 147, Level 15, State 1, Line 3 An aggregate may not appear in the WHERE clause unless it is in a subquery contained in a HAVING clause or a select list, and the column being aggregated is an outer reference. He was not able to resolve this problem, even though the solution was given in the query description itself. Due to lack of experience he came up with another version of above query based on the error message. SELECT * FROM [Sales].[SalesOrderHeader] HAVING ShipDate = MAX(ShipDate) GO When he ran above query it produced another error. Msg 8121, Level 16, State 1, Line 3 Column ‘Sales.SalesOrderHeader.ShipDate’ is invalid in the HAVING clause because it is not contained in either an aggregate function or the GROUP BY clause. What he wanted actually was the SalesOrderHeader all the Sales shipped on the last day. Based on the problem statement what the right solution is as following, which does not generate error. SELECT * FROM [Sales].[SalesOrderHeader] WHERE ShipDate = (SELECT MAX(ShipDate) FROM [Sales].[SalesOrderHeader]) Well, that’s it! Very simple. With SQL Server there are always multiple solution to a single problem. Is there any other solution available to the problem stated? Please share in the comment.

  • Is there any evidence that lisp actually is better than other languages at artificial intelligence?

    - by Joe D
    I asked this question on SO but it was closed fairly promptly (within 3 minutes) because it was too subjective. I then thought to ask it here on Programmers, a site for "subjective questions on software development". Quoting from the original question: There seems to be a long-held belief (mainly by non-lispers) that lisp is only good for developing AI. Where did this belief originate? And is there any basis in fact to it?

  • Using DesktopCouch without Ubuntu One?

    - by burli
    I want to know if it is possible to use DesktopCouch without UbuntuOne, but with a local CouchDB Server. I found a pairing Tool, but this crashes, when I try to pair two computer. I can find the local Desktop Couches with the Avahi Zeroconf Browser and it should be possible to find them with Python and start a replication To make a long story short: I want to sync DesktopCouch Databases in my local network without Ubuntu One. Is that possible?

  • Harnessing Business Events for Predictive Decision Making - part 1 / 3

    - by Sanjeev Sharma
    Businesses have long relied on data mining to elicit patterns and forecast future demand and supply trends. Improvements in computing hardware, specifically storage and compute capacity, have significantly enhanced the ability to store and analyze mountains of data in ever shrinking time-frames. Nevertheless, the reality is that data growth is outpacing storage capacity by a factor of two and computing power is still very much bounded by Moore's Law, doubling only every 18 months.Faced with this data explosion, businesses are exploring means to develop human brain-like capabilities in their decision systems (including BI and Analytics) to make sense of the data storm, in other words business events, in real-time and respond pro-actively rather than re-actively. It is more like having a little bit of the right information just a little bit before hand than having all of the right information after the fact. To appreciate this thought better let's first understand the workings of the human brain.Neuroscience research has revealed that the human brain is predictive in nature and that talent is nothing more than exceptional predictive ability. The cerebral-cortex, part of the human brain responsible for cognition, thought, language etc., comprises of five layers. The lowest layer in the hierarchy is responsible for sensory perception i.e. discrete, detail-oriented tasks whereas each of the above layers increasingly focused on assembling higher-order conceptual models. Information flows both up and down the layered memory hierarchy. This allows the conceptual mental-models to be refined over-time through experience and repetition. Secondly, and more importantly, the top-layers are able to prime the lower layers to anticipate certain events based on the existing mental-models thereby giving the brain a predictive ability. In a way the human brain develops a "memory of the future", some sort of an anticipatory thinking which let's it predict based on occurrence of events in real-time. A higher order of predictive ability stems from being able to recognize the lack of certain events. For instance, it is one thing to recognize the beats in a music track and another to detect beats that were missed, which involves a higher order predictive ability.Existing decision systems analyze historical data to identify patterns and use statistical forecasting techniques to drive planning. They are similar to the human-brain in that they employ business rules very much like mental-models to chunk and classify information. However unlike the human brain existing decision systems are unable to evolve these rules automatically (AI still best suited for highly specific tasks) and  predict the future based on real-time business events. Mistake me not,  existing decision systems remain vital to driving long-term and broader business planning. For instance, a telco will still rely on BI and Analytics software to plan promotions and optimize inventory but tap into business events enabled predictive insight to identify specifically which customers are likely to churn and engage with them pro-actively. In the next post, i will depict the technology components that enable businesses to harness real-time events and drive predictive decision making.

  • Kernel module implementation estimate

    - by Ivan Teterevkov
    I have a very abstract question about a kernel module writing estimate. How much dev-hours/months may required to write or, especially, port an existant kernel driver for a new PCI HBA from one operating system to another (with different kernel API)? I am porting an already written kernel module for 82599 for Linux kernel to OS X's IOKit and try to get a working alpha. I can't imagine for how long this task may expand in time.

  • Backup Compression - time for an overhaul

    - by jchang
    Database backup compression is incredibly useful and valuable. This became popular with then Imceda (later Quest and now Dell) LiteSpeed. SQL Server version 2008 added backup compression for Enterprise Edition only. The SQL Server EE native backup feature only allows a single compression algorithm, one that elects for CPU efficiency over the degree of compression achieved. In the long ago past, this strategy was essential. But today the benefits are irrelevant while the lower compression is becoming...(read more)

  • How to "reverse-backport" a package available on earlier Ubuntu distribution to later Distribution?

    - by Adam Ryczkowski
    There are 4 packages I am using on 12.04 which are not available on 12.10: xkcd-browser ;-) cuttlefish bluphone xserver-xorg-input-synaptics (it allows for touchpad rotation that could go along screen rotation with randr) Is there any way of more-or-less automatic reverse-backporting? (I know, that one "solution" is to wait. But unless I know for how long I should do it, it doesn't solve anything.)

  • T-SQL bits - ROW_NUMBER

    - by MartinIsti
    About a month ago I found the SQLShare site which provides useful, clear tutorial videos of how to use some SQL functions, or how to fine tune a query. Their videos are roughly 3-5 minutes long and have proved to be very good for me with a strong BI background with less first-hand T-SQL experience. I decided to make notes of the ones I watched and found useful and instead of putting them into a word document somewhere locally I'll publish them on this blog so. These would be very simple and short...(read more)

  • What if you could work on anything you wanted?

    - by Nick Harrison
    What if you could work on anything you wanted? Redgate is doing an experiment of sorts this week.  Called Down Tools Week.    The idea is that they stopped working on their regular projects for a week and strike out on something that catches their attention and drives their passion. Evidently in many cases, these projects have turned out to be new features in their existing products that individual were interested in, some were internal iniatives and some where evidently off the wall new ideas.   Today is show and tell where they will share with each other what they have been working on. There may well be some interesting announcements coming out of this.    The prospects are exciting. I understand that Google does something similar allowing their employees a specified amount of time to work on projects of their own choosing.    This has been the breeding ground for some of my favorite services. It is a shame that more companies do not follow such practices.   Now I know that most companies cannot afford to shut down everything for a week and sometimes you can't really explore an interesting idea in 8 hours a week or however much time Google allocates, but still it may be worth while. What would happen if your company gave you as an individual 1 week each quarter to work on a project of your own design and see what happens?   I would be happen if you still had to get approval for before your week long adventure. Personally, I think that this could be a very effective use of training budgets.   Give me a week to research something on my own and you would be amazed at what I can find out.    Maybe this should be the prerequisite before starting a new project.   Stagger the team onboarding but have everyone spend a week long sabbatical studying BizTalk before starting a project that will hinge on BizTalk. The show and tell afterwards is a great way to keep everyone honest or at least reassure management that everyone is honest.    If your goal was to spend a week researching and exploring a new technology and you had to do a show and tell afterwards to show off what you had learned, then everyone can learn a bit of what you just learned.     Sounds like a promising win win for me. Maybe it is a pipe dream, but what if .... What would you work on if given the opportunity to work on anything you wanted?
