  • T-SQL User-Defined Functions: the good, the bad, and the ugly (part 3)

    - by Hugo Kornelis
    I showed why T-SQL scalar user-defined functions are bad for performance in two previous posts. In this post, I will show that CLR scalar user-defined functions are bad as well (though not always quite as bad as T-SQL scalar user-defined functions). I will admit that I had not really planned to cover CLR in this series. But shortly after publishing the first part , I received an email from Adam Machanic , which basically said that I should make clear that the information in that post does not apply...(read more)

  • Perl syntax error [closed]

    - by Linny
    I am a beginner taking a Perl programming course. We are trying to write a basic program for counting nucleotides in a DNA string. I'm getting syntax errors on the lines that have a single bracket on lines 28 & 70 and don't know why. It also reads that I have compilation errors. I have no idea where to start figuring that out. # The purpose of this program is to count the number of nucleotides in a strand. Each protein is counted separately # print "/n NOTE: Nucleotide counting /n"; # use strict; # enforce variable declarations use warnings; # enable compiler warnings # Display number of A,a,T,t,G,g,C,c, nucleotides in a word or sequence of letters. # my ($base) = ''; # an extracted letter from a string my ($nuceotide_count) = 0 ; # the current position within the word my ($position) = 0 ; # number of vowels in user-supplied word my ($word) = ''; # word to be processed my ($A_count) = 0 ; # of A nucleotides in the user-supplied sequence my ($a_count) = 0 ; # of A nucleotides in the user-supplied sequence my ($C_count) = 0 ; # of C nucleotides in the user-supplied sequence my ($c_count) = 0 ; # of C nucleotides in the user-supplied sequence my ($G_count) = 0 ; # of G nucleotides in the user-supplied sequence my ($g_count) = 0 ; # of G nucleotides in the user-supplied sequence my ($T_count) = 0 ; # of T nucleotides in the user-supplied sequence my ($t_count) = 0 ; # of T nucleotides in the user-supplied sequence word = (STDIN) for ($position = 0);($position if (($base eq 'a') or ($base eq 'A')) { ++$A_count; } # end if ++$position; if (($base eq 'T') or ($base eq 't')) { ++$T_count; } end if ++$position; if (($base eq 'G') or ($base eq 'g')) { ++$G_count; } # end if ++$position; if (($base eq 'C') or ($base eq 'c')) { ++$C_count; } # end if ++$position; } # end for # Display final results. # print " \n The number of A or a neucleotides is: $A_count"; print " \n The number of T or t neucleotides is: $T_count"; print " \n The number of G or g neucleotides is: $G_count"; print " \n The number of C or c neucleotides is: $C_count"; print " \n\n Program completed successfully. \n" ; exit ;

  • JDK bug migration milestone: JIRA now the system of record

    - by darcy
    I'm pleased to announce the OpenJDK bug database migration project has reached a significant milestone: the JDK has switched from the legacy Sun "bugtraq" system to a new internal JIRA instance as the system of record for our bug tracking. This completes the initial phase of the previously described plan of getting OpenJDK onto an externally visible and writable bug tracker. The identities contained in the current system include recognized OpenJDK contributors. The bug migration effort to date has been sizable in multiple dimensions. There are around 140,000 distinct issues imported into the JDK project of the JIRA instance, nearly 165,000 if backport issues to track multiple-release information are included. Separately, the Code Tools OpenJDK project has its own JIRA project populated with several thousands existing bugs. Once the OpenJDK JIRA instance is externalized, approved OpenJDK projects will be able to request the creation of a JIRA project for issue tracking. There are many differences in the schema used to model bugs between the legacy bug system and the schema for the new JIRA projects. We've favored simplifications to the existing system where possible and, after much discussion, we've settled on five main states for the OpenJDK JIRA projects: New Open In progress Resolved Closed The Open and In-progress states can have a substate Understanding field set to track whether the issues has its "Cause Known" or "Fix understood". In the closed state, a Verification field can indicate whether a fix has been verified, unverified, or if the fix has failed. At the moment, there will be very little externally visible difference between JIRA for OpenJDK and the legacy system it replaces. One difference is that bug numbers for newly filed issues in the JIRA JDK project will be 8000000 and above. If you are working with JDK Hg repositories, update any local copies of jcheck to the latest version which recognizes this expanded bug range. (The bug numbers of existing issues have been preserved on the import into JIRA). Relatively soon, we plan for the pages published on bugs.sun.com to be generated from information in JIRA rather than in the legacy system. When this occurs, there will be some differences in the page display and the terminology used will be revised to reflect JIRA usage, such as referring to the "component/subcomponent" of an issue rather than its "category". The exact timing of this transition will be announced when it is known. We don't currently have a firm timeline for externalization of the JIRA system. Updates will be provided as they become available. However, that is unlikely to happen before JavaOne next week!

  • 2011 - ALMs for your development team and the people they work with.

    - by David V. Corbin
    Welcome to 2011, it is already shaping up to be a very exciting year. The title of the post is not about charitable giving, although that is also a great topic. Application Lifecycle Management and the Systems that support the environment is, and 2011 will be a year where I expect many teams to invest heavily in this area. For those not familiar with ALM, it can be simplified down to "A comprehensive view of all of the iteas, requirements, activities and artifacts that impact an application over the course of its lifecycle, from concept until decommissioning". Obviously, this encompases a large number of different areas even for relatively small and medium sized projects. In recent years, many teams have adapted methodoligies which address individual aspects of this; but the majority of this adoption has resulted in "islands of improvement" rather than the desired comprehensive outcome...Until now! Last year Microsoft released Team Foundation Server 2010 along with Visual Studio 2010 Ultimate Edition, and with these two in combination the situation has drastically changed. At last there is a single environment that is capable of handling all aspects of ALM, and is also capable of dealing with migration and integration with existing systems to make the transition to a single solution much easier. Thse possibilities (and practicalities) are nothing short of amazing, Architecture thru Testing integration? YES. Being able to correlate specific requirement items (and their history) to actual code (and code history)? YES. Identification of which tests will be potentially impacted by a given code change? YES. Resiliant Automated Testing of User Interfaces? YES. Automatic Deployment Management? YES. Integraton Level testing as part of (designated) Builds? YES. I could easily double or triple the above list, but these items should be enough to get you thinking about the "pain points" your team and organization currently face and the fact that there IS a way to relieve the pain. Over the course of the year, I am hoping to bring together some of the "best of breed" information, along with hosting (and participating in) discussions with various experts in the field. There are already a number of groups (including many on LinkedIn) that have an ALM focus, and I encourage everyone out to check them out. I will be posting a list of the ones I find most helpful in the not too distant future. As I said at the beginning, 2011 is shaping up to be a very interesting (and productive) year. Why wait to start investigating and adopting ALM? ps: For those interested in becoming an "Alms Giver" in the charitable sense, I highly recommend checking out GiveCamp. A group of developers, designers and others get together to create a solution for a charity in just under 48 hours. I will be attending the GiveCamp in New York City on Jan 14-16, more information is available at nycgivecamp.org/

  • Startup a Ubuntu FTP and SSH server without logging in

    - by Jenko
    I have a Ubuntu Server 11.10 box, which I would like to run "headless", and without a keyboard, mouse or display. Is it possible that immediately after startup the machine logs into an account, or allows me to control the machine from my Windows 7 machine nearby via SSH and SFTP? I've got OpenSSH server installed, and even when the box is not logged in I can start an SSH session. I've tried installing VSFTPD but its very troublesome (hardly connects) and only starts when I login locally into the box.

  • Make Browsing Safer for Children in Google Chrome

    - by Asian Angel
    If you are worried about the websites that your children could accidentally visit while browsing, then you may want to have a look at the Kid Safe – LinkExtend extension for Google Chrome. Kid Safe – LinkExtend in Action Before going any further you may want to have a quick look at the options. Everything is enabled by default but it is recommended that you disable the “Allow entering unsafe sites Option”. For our first example we visited “chatroulette.com”. As you can see in the screenshot WOT and McAfee SiteAdvisor gave the website a “green rating” but when it came specifically to its’ level of appropriateness for children LinkExtend gave it a “yellow rating”. Our second example was “hotbabes.com”…obviously not a good website for any child to visit. You can see that the entire window area has been totally “blacked out” and the available information for this site from each of the six ratings sources. The “Toolbar Button” is also displaying a “red rating”… Notice the two links at the bottom of the ratings screen…both will be visible if the “Allow entering unsafe sites Option” is not disabled (see Options above). You can see the difference for the links at the bottom of the ratings screen if you have the “Allow entering unsafe sites Option” disabled. Definitely much much better… Clicking on the “Find Kids Sites Link” will navigate the tab to the Yahoo! Kids website. The extension will also place “ratings buttons” beside search results at Google. As you can see in the screenshot below not all of the results had information available for them at this time. But it is certainly a lot better than nothing at all when it comes to keeping your children safe. A close-up look at the ratings for one of the search results. Conclusion While no browser add-in makes for a perfect solution the Kid Safe – LinkExtend extension will definitely be a helpful addition to your family’s Chrome browser.

  • Customer Experience and BPM – From Efficiency to Engagement

    - by Ajay Khanna
    Over the last few years, focus of BPM has been mainly to improve the businesses efficiency. To create more efficient processes, to remove bottlenecks, to automate processes. That still holds true and why not? Isn’t BPM all about continuous improvement? BPM facilitates and requires business and IT collaboration. But business also requires working with customer. Do we not want to get close to and collaborate with our customers? This is where Social BPM takes BPM a step further. It not only allows people within an organization to collaborate to design exceptional processes, not only lets them collaborate on resolving a case but also let them engage with the customers. Engaging with customer means, first of all, connecting with them on their terms and turf. Take a new account opening process. Can a customer call you and initiate the process? Can a customer email you, or go to the website and initiate the process? Can they tweet you and initiate the process? Can they check the status of process via any channel they like? Can they take a picture of damaged package delivery and kick-off a returns process from their mobile device, with GIS data? Yes, these are various aspects to consider during process design if the goal is better customer experience and engagement. Of course, we want to be efficient and agile, but the focus here needs to be the customer. Now when the customer is tweeting about your products, posting on Facebook and Yelp about their experience with your company (and your process), you need to seek out that information. You need to gather and analyze the customer’s feedback on the social media and use that information to improve the processes and products. This is an excellent source of product and process ideation. So BPM is no longer only about improving back-office process efficiency, it is moving into a new and exciting phase of improving frontline customer facing processes, customer experience and engagement. Let me know how you think BPM can enhance customer experience.

  • determine collision angle on a rotating body

    - by jorb
    update: new diagram and updated description I have a contact listener set up to try and determine the side that a collision happened at relative to the a bodies rotation. One way to solve this is to find the value of the yellow angle between the red and blue vectors drawn above. The angle can be found by taking the arc cosine of the dot product of the two vectors (Evan pointed this out). One of my points of confusion is the difference in domain of the atan2 function html canvas coordinates and the Box2d rotation information. I know I have to account for this somehow... SS below questions: Does Box2D provide these angles more directly in the collision information? Am I even on the right track? If so, any hints? I have the following javascript so far: Ship.prototype.onCollide = function (other_ent,cx,cy) { var pos = this.body.GetPosition(); //collision position relative to body var d_cx = pos.x - cx; var d_cy = pos.y - cy; //length of initial vector var len = Math.sqrt(Math.pow(pos.x -cx,2) + Math.pow(pos.y-cy,2)); //body angle - can over rotate hence mod 2*Pi var ang = this.body.GetAngle() % (Math.PI * 2); //vector representing body's angle - same magnitude as the first var b_vx = len * Math.cos(ang); var b_vy = len * Math.sin(ang); //dot product of the two vectors var dot_prod = d_cx * b_vx + d_cy * b_vy; //new calculation of difference in angle - NOT WORKING! var d_ang = Math.acos(dot_prod); var side; if (Math.abs(d_ang) < Math.PI/2 ) side = "front"; else side = "back"; console.log("length",len); console.log("pos:",pos.x,pos.y); console.log("offs:",d_cx,d_cy); console.log("body vec",b_vx,b_vy); console.log("body angle:",ang); console.log("dot product",dot_prod); console.log("result:",d_ang); console.log("side",side); console.log("------------------------"); }
