• transform longitude latitude into meters

  - by Sponge

  I need a function that maps gps positions to x/y values like this: getXYpos(GeoPoint relativeNullPoint, GeoPoint p){ deltaLatitude=p.latitude-relativeNullPoint.latitude; deltaLongitude=p.longitude-relativeNullPoint.longitude; ... resultX=latitude (or west to east) distance in meters from p to relativeNullPoint resultY=longitude (or south to north) distance in meters from p to relativeNullPoint } i have seen some implementations of "distance of two geoPoints" but they all just calculate the air-line distance. i think the deltaLongitude can be transformed into meters directly but the deltaLatitude depends in the Longitude. does anyone know how this problem can be solved?

• Try to fill the GAE datastore but the code consumes to much cpu time. How to optimize this?

  - by Neverland

  I try to get the list of images in Amazon EC2 inside the Google datastore. I want to realize this with a cron job inside the GAE. class AmazonEC2uswest(db.Model): ami = db.StringProperty(required=True) mani = db.StringProperty() typ = db.StringProperty() arch = db.StringProperty() state = db.StringProperty() owner = db.StringProperty() class CronAMIsAmazonUS_WEST(webapp.RequestHandler): def get(self): aws_access_key_id_admin = "<secret>" aws_secret_access_key_admin = "<secret>" conn_us_west = boto.ec2.connect_to_region('us-west-1', aws_access_key_id=aws_access_key_id_admin, aws_secret_access_key=aws_secret_access_key_admin, is_secure = False) liste_images_us_west = conn_us_west.get_all_images() laenge_liste_images_us_west = len(liste_images_us_west) for i in range(laenge_liste_images_us_west): datastore_uswest_AMIs = AmazonEC2uswest(ami=liste_images_us_west[i].id, mani=str(liste_images_us_west[i].location), typ=liste_images_us_west[i].type, arch=liste_images_us_west[i].architecture, state=liste_images_us_west[i].state, owner=liste_images_us_west[i].ownerId) datastore_uswest_AMIs.put() The problem: Getting the list with get_all_images() lasts only a few seconds. But writing the data to the Google datastore needs way too much CPU time. My IBM T42p (P4M with 2GHz) needs for that piece of code approx. 1 Minute! Is it possible to optimize my code in a way that it needs fewer CPU time?

• How to get global access to enum types in C#?

  - by lala

  This is probably a stupid question, but I can't seem to do it. I want to set up some enums in one class like this: public enum Direction { north, east, south, west }; Then have that enum type accessible to all classes so that some other class could for instance have: Direction dir = north; and be able to pass the enum type between classes: public void changeDirection(Direction direction) { dir = direction; } I thought that setting the enum to public would make this automatically possible, but it doesn't seem to be visible outside of the class I declared the enum in.

• AWS Load Balancer with a static IP address

  - by user965904

  I have a set-up running on Amazon cloud with a couple of EC2 Instances running through a load balancer. It is important that the site has a unique(static) IP or set of IPs as I'm plugging in 3rd party APIs which only accept requests made from IPs which have been added to their whitelist. So basically unless we can give these 3rd parties a static IP or range of IPs that the requests from the site will always come from then we would be unable to make any calls to them. Anyone knows how to achieve this as I know that Elastic IPs are not compatible with load balancers? If I were to look up the IP of the load balancer DNS name (e.g. dualstack.awseb-BAMobile-ENV-xxxxxxxxx.eu-west-1.elb.amazonaws.com resolves to 200.200.200.200) would that IP be Static? Any help/advise is greatly appreciated guys.

• XNA Notes 009

  - by George Clingerman

  This past week the MVPs (myself included) were on Microsoft campus for the MVP summit. So I apologize in advance if you did something cool or heard of something cool happening with XNA and XBLIGs and it’s not in my notes. I did my best to stay on top of things, but honestly this community is fast and furious with what it’s doing and creating. I really can’t keep up and that’s fantastic!

• Book Review: Inside Windows Communicat?ion Foundation by Justin Smith

  - by Sam Abraham

  In gearing up for a new major project, I have taken it upon myself to research and review various aspects of our Microsoft stack of choice seeking new creative ways for us to leverage in our upcoming state-of-the-art solution projected to position us ahead of the competition. While I am a big supporter of search engines and online articles as a quick and usually reliable source of information, I have opted in my investigative quest to actually “hit the books”.  I have also made it a habit to provide quick reviews for material I go over hoping this can be of help to someone who may be looking for items others may have had success using for reference. I have started a few months ago by investigating better ways to implementing, profiling and troubleshooting SQL Server 2008. My reference of choice was Itzik Ben-Gan et al’s “Inside Microsoft SQL Server 2008” series. While it has been a month since my last book review, this by no means meant that I have been sitting idle. It has been pretty challenging to balance research with the continuous flow of projects and deadlines all while balancing that with my family duties which, of course, always comes first. In this post, I will be providing a quick review of my latest reading: Inside Windows Communication Foundation by Justin Smith. This book has been on my reading list for a very long time and I am proud to have finally tackled it. Justin’s book presents a great coverage of WCF internals. His simple, concise and well-worded style has simplified the relatively complex internals of WCF and made it comprehensible. Justin opted to organize the book into three parts: an introduction to WCF, coverage of the Channel Layer and a look at WCF internals at the ServiceModel layer. Part I introduced the concepts and made the case behind WCF while covering a simplified version of WCF’s message patterns, endpoints and contracts. In Part II, Justin provided a thorough coverage of the internals of Messages, Channels and Channel Managers. Part III concluded this nice reading with coverage of Bindings, Contracts, Dispatchers and Clients. While one would not likely need to extend WCF at that low level of the API, an understanding of the inner-workings of WCF is a must to avoid pitfalls mainly caused by misinformation or erroneous assumptions. Problems can quickly arise in high-traffic hosted solutions, but most can be easily avoided with some minimal time investment and education. My next goal is to pay a closer look at WCF from the programmer’s API perspective now that I have acquired a better understanding of its inner working.   Many thanks to the O’Reilly User Group Program and its support of our West Palm Beach Developers’ Group.   Stay tuned for more… All the best, --Sam

• SQL Developer: Why Do You Require Semicolons When Executing SQL in the Worksheet?

  - by thatjeffsmith

  There are many database tools out there that support Oracle database. Oracle SQL Developer just happens to be the one that is produced and shipped by the same folks that bring you the database product. Several other 3rd party tools out there allow you to have a collection of SQL statements in their editor and execute them without requiring a statement delimiter (usually a semicolon.) Let’s look at a quick example: select * from scott.emp select * from hr.employees delete from HR_COPY.BEER where HR_COPY.BEER.STATE like '%West Virginia% In some tools, you can simply place your cursor on say the 2nd statement and ask to execute that statement. The tool assumes that the blank line between it and the next statement, a DELETE, serves as a statement delimiter. This is not bad in and of itself. However, it is very important to understand how your tools work. If you were to try the same trick by running the delete statement, it would empty my entire BEER table instead of just trimming out the breweries from my home state. SQL Developer only executes what you ask it to execute You can paste this same code into SQL Developer and run it without problems and without having to add semicolons to your statements. Highlight what you want executed, and hit Ctrl-Enter If you don’t highlight the text, here’s what you’ll see: See the statement at the cursor vs what SQL Developer actually executed? The parser looks for a query and keeps going until the statement is terminated with a semicolon – UNLESS it’s highlighted, then it assumes you only want to execute what is highlighted. In both cases you are being explicit with what is being sent to the database. Again, there’s not necessarily a ‘right’ or ‘wrong’ debate here. What you need to be aware of is the differences and to learn new workflows if you are moving from other database tools to Oracle SQL Developer. I say, when in doubt, back away from the tool, especially if you’re in production. Oh, and to answer the original question… Because we’re trying to emulate SQL*Plus behavior. You end statements in SQL*Plus with delimiters, and the default delimiter is a semicolon.

• NYC Silverlight FireStarter - June 5th 2010 at the NYC Microsoft Office

  - by Sam Abraham

  On Saturday June 5th, 2010, I spent my Saturday morning at the NYC Silverlight FireStarter. Presenting was Peter Laudati from Microsoft and Jason Beres, Matt Van Horn and Todd Snyder from Infragistics. I watched the Simulcast for the morning sessions as I was tied up with some work, but ended up finally making it to the Microsoft Office and had the opportunity to attend the last hour of the event in person.   For me, the quality of the Simulcast was as good as in-person attendance so far as sound/video quality and the interaction with speakers. In the background was a screen with tweets from remote attendees asking questions or commenting on the presentations. Presenters did periodically stop to answer the tweeted questions as well as questions from attendees. Only thing I missed was getting my hands on some of that swag that was (literally) flying in the air at the event floor.   Upon my arrival at the Microsoft Office Location in NYC, I spoke with Rachel Appel and Peter Laudati asking for permission to take a few photos to record the outstanding effort that took place in putting this event together. Both agreed and I started with putting my photography skills to work.   You can always gauge the quality of an event with the number of its attendees who opt to stay till the last minute as well as the level of interaction of the audience with the speaker. With most of the FireStarter attendees remaining till the very end of the talk, and with the many questions that were asked, one can simply judge the event as a success as per my aforementioned criteria.   Evaluation forms were passed around and Peter strongly encouraged the audience to openly speak their mind as they record their comments. I didn't get to submit my evaluation as I was busy recording the event in photos, so here it goes: I believe that lots of hard work was put into making this event a reality. Quality of speakers, topics and level of Geekiness at the event was outstanding.  Overall, aside from a minor issue with Lunch delivery time, this event was of high quality and I am very sure everyone's evaluation will be in line with my analysis of it being a great success. Below are a few photos of the event.   --Sam Abraham Site Director - West Palm Beach .Net User Group www.Fladotnet.com     NYC Silverlight FireStarter Speakers - From Left to right: Peter Laudati, Todd Snyder, Matt Van Horn & Jason Beres   As jason wasn't quiet visible in the above photo, a closeup was taken (It was Jason's birthday and he had to leave a bit early, so the Infagisticts team thought outside the box...)     Full Room - That was at the last hour of the event   Another view of full room   Discussions during the break   End-of-event Raffle

• The Politics of Junk Filtering

  - by mikef

  If the national postal service, such as the Royal Mail in the UK, were to go through your letters and throw away all the stuff it considered to be junk instead of delivering it to you, you might be rather pleased until you discovered that it took a too liberal decision about what was junk. Catalogs you'd asked for? Junk! Requests from charities? Who needs them! Parcels from competing carriers? Toss them away! The possibility for abuse for an agency that was in a monopolistic position is just too scary to tolerate. After all, the postal service could charge 'consultancy fees' to any sender who wanted to guarantee that his stuff got delivered, or they could even farm this out to other companies. Because Microsoft Outlook is just about the only email client used by the international business community in the west, its' SPAM filter is the final arbiter as to what gets read. My Outlook 2007, set to the default settings, junks all the perfectly innocent email newsletters that I subscribe to. Whereas Google Mail, Yahoo, and LIVE are all pretty accurate in detecting spam, Outlook makes all sorts of silly mistakes. The documentation speaks techno-babble about 'advanced heuristics', but the result boils down to an inaccurate mess. The more that Microsoft fiddles with it, the stickier the mess. To make matters worse, it still lets through obvious spam. The filter is occasionally updated along with other automatic 'security' updates you opt for automatic updates. As an editor for a popular online publication that provides a newsletter service, this is an obvious source of frustration. We follow all the best-practices we know about. We ensure that it is a trivial task to opt out of receiving it. We format the newsletter to the requirements of the Service Providers. We follow up, and resolve, every complaint. As a result, it gets delivered. It is galling to discover that, after all that effort, Outlook then often judges the contents to be junk on a whim, so you don't get to see it. A few days ago, Microsoft published the PST file format specification, under pressure from a European Union interoperability investigation by ECIS (the European Committee for Interoperable Systems). The objective was that other applications could then access existing PST files so as to migrate from existing Outlook installations to other solutions. Joaquín Almunia, the current competition commissioner, should now turn his attention to the more subtle problems of Microsoft Outlook. The Junk problem seems to have come from clumsy implementation of client-side spam filtering rather than from deliberate exploitation of a monopoly on the desktop email client for businesses, but it is a growing problem nonetheless. Cheers, Michael Francis

• Leading an offshore team

  - by Chuck Conway

  I'm in a position where I am leading two teams of 4. Both teams are located in India. I am on the west coast of the U.S. I'm finding leading remote teams challenging: First, their command of the English language is weak. Second, I'm having difficultly understanding them through their accents. Third is timing, we are 12 hours apart. We use Skype to communicate. I have a month to get the project done. We've burned through a week just setting up the environments. At this point I'm considering working their hours, 11p PDT to 7a PDT, to get them up to speed, so that I can get the project off the ground. A 12 hour lag time is too much. I'm looking for steps I can take to be successful at leading an offshore team. Update The offshore team's primary task is coding, of course, most coding tasks do involve some design work. The offshore team's are composed of one lead, 2 mid level (4 to 5 years) developers and a junior (~2 years) developer. The project is classic waterfall. We've handed the offshore team a business and a technical design document. We are trying to manage the offshore in an agile way. We have daily conference calls with them and I'm requiring the teams to send me a daily scrum in the form of an email answering the following questions: What did I do today? What am I going to do tomorrow? What do I need from Chuck so I can do my job tomorrow? There is some ambiguity in the tasks. The intent was to give them enough direction for them to develop the task with out writing the code for them. I don't have a travel budget. I am using Fogbugz to track the tasks. Each task has been entered into Fogbugz and given a priority. Each team member has access to FogBugz and can choose what task they wish to complete. Related question: What can we do to improve the way outsourcing/offshoring works? Update 2 I've decided that I can not talk to the team once a day. I must work with them. Starting tonight I've started working the same hours they are. This makes me available to them when they have questions. It also allows me to gain their trust and respect.

• Hello From South Florida

  - by Sam Abraham

  Fellow Blog Readers: I figured I use my first blog post on GeeksWithBlogs to introduce myself.   I recently relocated from Long Island, NY to South Florida where I joined a local company as Software Engineer specializing in technologies such as C#, ASP.Net 3.5, WCF, Silverlight, SQL Server 2008 and LINQ, to name a few. I am an MCP and MCTS ASP.Net 3.5, looking to get my .Net 4.0 certification soon.   Having been in industry for a few years so far, I figured I would share with you my take on the importance of being involved(at least attending) in local user groups.   I am a firm believer that besides using a certain technology, the best way to expand one’s knowledge is by sharing it with others and being equally open to learn from others just as much as you are willing to share what you know.   In my opinion, an important factor that makes a good developer stand-out is his/her ability to keep abreast with the latest and greatest even in areas outside his/her direct expertise.   Additionally, having spoken to various recruiters, technical user group attendees are always favorably looked upon as genuinely interested in their field and willing to take the initiative to expand their knowledge which offers job candidates good leverage when competing for jobs.   I believe I am very blessed to be in an area with a very strong and vibrant developer community. I found in the local .Net community leadership a genuine interest in constantly extending the opportunity to all developers to get more involved and encouraging those who are willing to take that initiative achieve their goal: Speak in meetings, volunteer at events or write and publish articles/blogs about latest and greatest technologies.   With Vishal Shukla (Site director for the West Palm Beach .Net User Group) traveling overseas, I have been extended the opportunity to come on board as site coordinator for FladotNet's WPB .Net User Group along with Venkata Subramanian, an opportunity which I gratefully accepted.   Being involved in running a .Net User Group will surely help me personally and professionally, but my real hope is to use this opportunity to assist in delivering the ultimate common-goal: spread the word about new .Net Technologies, help everybody get more involved and simply have fun learning new things.   With my introduction out of the way, in the next few days I will be posting some notes on an upcoming talk I will be giving about MVC2 and VS2010 in mid-April.   Environment.Exit(0); --Sam

• Proxy settings do not promulgate to fat or thin clients

  - by solizin47

  I work in Hertfordshire schools, which use a proxy eg http://wf1.thegrid.org.uk on port 80 to allow graded access by all users, within the schools, to the Internet. I have Ubuntu 10.04LTS successfully running and I want to set up 12.04LTS to replace it. Many other replies to this question have answered questions about stand-alone computers and not addressed the LTSP server and its clients. I have come to a complete stop over the problem of the proxy server settings not promulgating over the local network to Ubuntu 12.04 thin or fat clients. When you input this setting (there are others for HTTPS and FTP) into the System Settings/Network Manager GUI on the server, then when a user logs into the server, both Firefox and Chrome can read the settings and will gain access to the Internet. HOWEVER, these settings are not promulgated to either thin or fat clients on the local network. Their System Settings/Network Manager GUI remains stubbornly blank. I have rebuilt the image after inputting the proxy settings, but it appears they are not part of the image. /etc/environment (on the server) already has: PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games" http_proxy="http://wf1.thegrid.org.uk:80/" https_proxy="https://wf1.thegrid.org.uk:80/" ftp_proxy="ftp://proxy.intra.thegrid.org.uk:3128/" I have also tried this export http_proxy="http://wf1.thegrid.org.uk:80" export https_proxy="http://wf1.thegrid.org.uk:80" export ftp_proxy="http://proxy.intra.thegrid.org.uk:3128" within /etc/environment, and that had no effect, either. etc/apt/apt.conf also has: Acquire::http::proxy "http://wf1.thegrid.org.uk:80/"; Acquire::https::proxy "https://wf1.thegrid.org.uk:80/"; Acquire::ftp::proxy "ftp://proxy.intra.thegrid.org.uk:3128/"; The clients still have no proxy settings in their Network Manager, and no client user can access the Internet from Firefox or Chrome. Three questions: Why doesn't the “Apply system wide” button work? It does on 10.04, and every new user, and all existing users have access to the internet through the proxy without problem. How can I set up proxy settings that work for all the 12.04 clients? I noticed that if user West input the settings himself, they would follow him around the clients. However, this is not secure, because there are grades of settings which prevent visits to various sites, eg wf3 allows fewer sites than wf2 or wf1, so I can't allow users to input this setting themselves. Since the proxy setting followed the user around the clients, the setting must be somewhere in the user profile, since none of the other users have the proxy settings. Do you know where, and how I could fix the setting for users, or better, groups? The setting must then be unchangeable by the user, with no access to the Network Manager. If either 2. or 3. can't be done, then the Ubuntu 12.04LTS server is simply no use to us...
