  • How to resume an ftp download at any point? (shell script, wget option)?

    - by Dave
    hi! i want to download a huge file from an ftp server in chunks of 50-100MB each. At each point, i want to be able to set the "starting" point and the length of the chunk i want. i wont have the "previous" chunks saved locally (ie i cant ask the program to "resume" the downlaod). what is the best way of going about that? i use wget mostly, but would something else be better?

  • How can I compare market data feed sources for quality and latency improvement?

    - by yves Baumes
    I am in the very first stages of implementing a tool to compare 2 market data feed sources in order to prove the quality of new developed sources to my boss ( meaning there are no regressions, no missed updates, or wrong ), and to prove latencies improvement. So the tool I need must be able to check updates differences as well as to tell which source is the best (in term of latency). Concrectly, reference source could be Reuters while the other one is a Feed handler we develop internally. People warned me that updates might not arrive in the same order as Reuters implementation could differs totally from ours. Therefore a simple algorithm based on the fact that updates could arrive in the same order is likely not to work. My very first idea would be to use fingerprint to compare feed sources, as Shazaam application does to find the title of the tube you are submitting. Google told me it is based on FFT. And I was wondering if signal processing theory could behaves well with market access applications. I wanted to know your own experience in that field, is that possible to develop a quite accurate algorithm to meet the needs? What was your own idea? What do you think about fingerprint based comparison?

  • Any significant performance improvement by using bitwise operators instead of plain int sums in C#?

    - by tunnuz
    Hello, I started working with C# a few weeks ago and I'm now in a situation where I need to build up a "bit set" flag to handle different cases in an algorithm. I have thus two options: enum RelativePositioning { LEFT = 0, RIGHT = 1, BOTTOM = 2, TOP = 3, FRONT = 4, BACK = 5 } pos = ((eye.X < minCorner.X ? 1 : 0) << RelativePositioning.LEFT) + ((eye.X > maxCorner.X ? 1 : 0) << RelativePositioning.RIGHT) + ((eye.Y < minCorner.Y ? 1 : 0) << RelativePositioning.BOTTOM) + ((eye.Y > maxCorner.Y ? 1 : 0) << RelativePositioning.TOP) + ((eye.Z < minCorner.Z ? 1 : 0) << RelativePositioning.FRONT) + ((eye.Z > maxCorner.Z ? 1 : 0) << RelativePositioning.BACK); Or: enum RelativePositioning { LEFT = 1, RIGHT = 2, BOTTOM = 4, TOP = 8, FRONT = 16, BACK = 32 } if (eye.X < minCorner.X) { pos += RelativePositioning.LEFT; } if (eye.X > maxCorner.X) { pos += RelativePositioning.RIGHT; } if (eye.Y < minCorner.Y) { pos += RelativePositioning.BOTTOM; } if (eye.Y > maxCorner.Y) { pos += RelativePositioning.TOP; } if (eye.Z > maxCorner.Z) { pos += RelativePositioning.FRONT; } if (eye.Z < minCorner.Z) { pos += RelativePositioning.BACK; } I could have used something as ((eye.X > maxCorner.X) << 1) but C# does not allow implicit casting from bool to int and the ternary operator was similar enough. My question now is: is there any performance improvement in using the first version over the second? Thank you Tommaso

  • Adventures in Lab Management Configuration: Part 2 of 3

    - by Enrique Lima
    The first post was the high level overview. Now it is time for the details on what was done to the existing CMMI Project based on CMMI v 4.2. The first step was to go into Visual Studio, then from the Team Project Collection Settings and then to the Process Template Manager.  Once there, it was a matter of selecting the appropriate template (MSF for CMMI Process Improvement v5.0) and download to a point I could reference later (for example C:\Templates). Then on to using the steps from the guidance post. Since I was using an x64 deployment, I will make reference to the path as <toolpath>, however the actual path to reference in a 64-bit environment is “C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE”. As I mentioned on the previous post, make sure to first perform a backup of the Configuration, Collection and Warehouse DBs.  If you did not apply any changes to the names and such, then you will find those as tfs_Configuration, tfs_DefaultCollection and tfs_Warehouse. Now, the work needed with the witadmin tool: That includes the uploading of the structures that differ from v4.2 to v5.0 There is likely going to be an issue with the naming of some fields. For example, TFS 2010 likes something along the lines of “Area ID”, whereas TFS 2008 would have had it as “AreaID”.  So, this will need to be corrected.  Some posts will have you go through this after the errors pop up.  I would recommend doing this process prior to executing the importwitd process.  witadmin listfields /collection:<path to collection> > c:\ListFields.txt Review the following fields: AreaID, review the Name property and validate if it states “AreaID”, the you will need to rename the Name field to reflect “Area ID”. ExternalLinkCount, RelatedLinkCount, HyperLinkCount, AttachedFileCount and IterationID would be the other fields to check. To correct the issue, then execute the following: witadmin changefield /collection:<path to collection> /n:"System.ExternalLinkCount" /name:"External Link Count" Repeat for Area ID, Related Link Count, Hyperlink Count, Attached File Count and Iteration ID.  Once this is done, proceed with the commands below. witadmin importwitd /collection:<path to collection> /p:<project> /f:"<path to downloaded template>\MSF for CMMI Process Improvement v5.0\WorkItem Tracking\TypeDefinitions\TestCase.xml" witadmin importwitd /collection:<path to collection> /p:<project> /f:"<path to downloaded template>\MSF for CMMI Process Improvement v5.0\WorkItem Tracking\TypeDefinitions\SharedStep.xml" witadmin importcategories /collection:<path to collection> /p:<project> /f:"<path to downloaded template>\MSF for CMMI Process Improvement v5.0\WorkItem Tracking\categories.xml" Modifications to the Bug Definition: First step is to export the existing definition. witadmin exportwitd /collection<path to collection> /p:<project> /n:bug /f:"<path to downloaded template>\MSF for CMMI Process Improvement v5.0\MyBug.xml" Make modifications to recently exported MyBug.xml file.  Details for the modification are here:  http://msdn.microsoft.com/en-us/library/ff452591.aspx#ModifyTask Once the changes are done, proceed with the import command witadmin importwitd /collection:<path to collection> /p: <project> /f:"<path to downloaded template>\MSF for CMMI Process Improvement v5.0\MyBug.xml" Repeat the process for the the Scenario or Requirement Type Definition witadmin exportwitd /collection<path to collection> /p:<project> /n:requirement /f:"<path to downloaded template>\MSF for CMMI Process Improvement v5.0\MyRequirement.xml" Make modifications to recently exported MyRequirement.xml file.  Details for the modification are here:  http://msdn.microsoft.com/en-us/library/ff452591.aspx#ModifyTask Once the changes are done, proceed with the import command witadmin importwitd /collection:<path to collection> /p: <project> /f:"<path to downloaded template>\MSF for CMMI Process Improvement v5.0\MyRequirement.xml" Provide the Bug Field Mapping definition, after creating the file as specified here: http://msdn.microsoft.com/en-us/library/ff452591.aspx#TCMBugFieldMapping tcm bugfieldmapping /import /mappingfile:"<path to downloaded template>\MSF for CMMI Process Improvement v5.0\bugfieldmappings.xml" /collection:<path to collection> /teamproject:<project name>

  • Perl : how to interrupt/resume loop by user hitting a key?

    - by Michael Mao
    Hi all: This is for debugging purpose. I've got a for loop that generates some output to Cygwin bash's CLI. I know that I can redirect outputs to text files and use Perl or even just a normal text editor to inspect the values printed out for a particular iteration, just feel that a bit painful. What I am now thinking is, to place a special subroutine inside the for loop, so that it would be "interrupted" at the beginning of each iteration, and Perl script should only resume to run after user/programmer hits a key(the Enter Key from keyboard?) In this way I can directly inspect the values printed out during each iteration. Is there a simple way to do this, without using additional libraries/CPAN ? Many thanks to the hints/suggestions in advance.

  • How can I suspend \ resume the video caputre operation in v4l2 ?

    - by Ita
    Hi, I use the v4l2 api for video capture and image applying image processing algo' on each frame. I wish to be able to suspend the video capture. I see that there are 2 options for ioctling (new verb, its gonna catch) the stream. VIDIOC_STREAMON, VIDIOC_STREAMOFF will start and stop the stream. Is there a way to suspend \ resume it? Is this even necessary, or can I just use the start and stop controls with no extra processing time spent on creating the stream all over again ? Thank you for your time, Itamar

  • What job title should be most suitable for my object in resume and what salary range should I expect

    - by user354177
    I was a classic asp developer in 2000. After a year of full-time employment, I left the field. I found a part-time position as an asp developer again in 2005 and taught myself vb.net. In 2007, I got the current full-time job as an Asp.net web developer. I taught myself C#, LING t0 SQL, Web Services, AJAX, and creating all kinds of reports with reporting services. One and half years ago, I sent myself to part-time graduate program in Database and Web Systems. I'll have two semesters to go and so far my GPA is 4.0/4.0. My job responsibility is to collect business requirements from other departments, design the database, write stored procedures, create aspx pages, and create reports. I love what I do and want to advance my career to the next level. What I enjoy most is to design the relational database. I would want to become an .Net Architect eventually. I got an interview. They were looking for asp.net web developer. But I was surprised and disappointed that position would only create aspx pages. I would not even have opportunity to write stored procedures, let alone design the database (those would be provided by another group). Furthermore, they asked me some detailed questions about web forms, some of which I did not know the answers. they might be disappointed as well. I am eager to learn and can apply what I learn to real projects right away. I believe no matter what specific skills I am lacking for a new position, I can catch up quickly. I am looking for $70k range job. The object in my resume is Experience C# Web Application Developer. Due to the experience from last interview, I wonder if the object is really what I want. Could somebody answer my questions? Thank you.

  • How to locally resume a session that has been started remotely using xrdp?

    - by Jaroslav Záruba
    Can I connect to a RD session that has been started (and abandoned) from a remote machine using xrdp? Also I'd like to be able to do the exact opposite: to remotely login to a session that has been initiated locally. I'm trying to get as close as possible to how Windows RS behaves. (Which also includes that the session would use my terminal machine/monitor resolution. I wasn't able to achieve that using VNC.) Suggestions to a better alternative to xrdp are welcome please. I don't know Linux too much.

  • How does the TuneIn mobile application resume a live stream, when the connection breaks?

    - by navnav
    So I have this TuneIn application on my phone, which allows me to listen to many radio stations. It also allows me to rewind and pause the live stream, which I know is doable with today's technology. What gets me puzzled, though, is how when the internet connection breaks, the live stream will stop, but, when the connection comes back, the app can just pick up from where it broke. Why it gets me puzzled is because there is no way for the app to cache the live stream when the net connection has gone, yet it can start the live stream back up, from where it broke. Is there is possible to start a live stream, at a specific point of the audio stream? Or are they using some other method?

  • How do I evaluate my skillset against the current market to see what needs improvement and where my

    - by baijajusav
    First of all, this question may be out of bounds for this site. If so, remove it. I say this because this site seems to be a place for more concrete questions that are not so relative in nature. And before I begin, for those of you whom just prefer a question and not this sort of dialog, here is my question: How can I assess my current skills as a programmer and decide where and what areas to improve upon? That said, here's what I'm asking/talking about, in essence. The market is always in constant flux. As programmers we're always having to learn new things, update our skills, push ourselves into that next project. There's not a very good litmus test that I know of for us to get an idea of where we stand as programmers. I came across this blog post by Jeff Atwood talking about why can't programmers code. Instinctively (and as the post goes on to state) I rushed through the program in about 4 minutes (most of that time was b/c I was hand writing it out. Still, this doesn't really answer the question of where do my skills need to be to succeed in today's world. I real blogs, listen to podcasts, try to keep up on the latest things coming out. It has only been in the past couple of months that I made a decision to pick a focus area for my learning as I can't learn everything and trying to do so is to spread myself too thin. I chose ASP.NET MVC & C#. I plan to stick with Microsoft technologies, not out of some sense of loyalty or stubbornness, but rather because they seem to stream together and have a unifying connection between them. With Windows Phone 7 coming out, it seems that now is the obvious time to pick up WPF and Silverlight as well. Still, if you asked me to code something apart from intellisense and the internet, I probably couldn't get the syntax right. I don't have libraries memorized or know precisely where the classes I use exist within the .Net framework, namely because I haven't had to pull that knowledge out of the air. In a way, I suppose Visual Studio has insulated me, which isn't a good thing, but, at the same time, I've still been able to be productive. I'm working on my own side project to try and help my learning. In doing so, I'm trying to make use of best practices and 3rd party frameworks where I can. I'm using automapper and EF 1.0. I know everyone in the .net community seems to cry foul at the sound of EF 1.0, but I can't say why because I've never used it. There's no lazy loading and that has proven rather annoying; however, aside from that, I haven't had that much of an issue. Granted this is probably because I'm not writing tests as I go (which I'm not doing because I don't know how to test EF in tests and don't really have a clue how to write tests for ASP.NET MVC 1.0). I'm also using a custom membership provider; granted, it's a barebone implementation, but I'm using it still. My thinking in all of this is, while I am neglecting a great many important technologies that are in the mainstream, I'll have a working project in the end. I can come back and add those things after I finish. Doing it all now and at once seems like too much. I know how I work and I don't think I'd ever get it done that way. I've elected to make this a community wiki as I think this question might fight better there. If a moderator disagrees with that choice or the decision to post this here, the just delete the question. I'm not trying to make undue work for anyone. I'm just a programmer trying to assess my where his skills are now and where I should be improving.

  • Queue ExternalInterface calls to Flash Object in UpdatePanel - Needs Improvement?

    - by Laramie
    A Flash (actually Flex) object is created on an ASP.Net page within an Update Panel using a modified version of the embedCallAC_FL_RunContent.js script so it can be written in dynamically. It is re-created with this script with each partial postback to that panel. There are also other Update Panels on the page. With some postbacks (partial and full), External Interface calls such as $get('FlashObj').ExternalInterfaceFunc('arg1', 0, true); are prepared server-side and added to the page using ScriptManager.RegisterStartupScript. They're embedded in a function and stuffed into Sys.Application's load event, for example Sys.Application.add_load(funcContainingExternalInterfaceCalls). The problem is that because the Flash object's state state may change with each partial postback, the Flash (Flex) object and/or External Interface may not be ready or even exist yet in the DOM when the JavaScript - Flash External Interface call is made. It results in an "Object doesn't support this property or method" exception. I have a working strategy to make the ExternalInterface calls immediately if Flash is ready or else queue them until such time that Flash announces its readiness. //Called when the Flash object is initialized and can accept ExternalInterfaceCalls var flashReady = false; //Called by Flash when object is fully initialized function setFlashReady() { flashReady = true; //Make any queued ExternalInterface calls, then dequeue while (extIntQueue.length > 0) (extIntQueue.shift())(); } var extIntQueue = []; function callExternalInterface(flashObjName, funcName, args) { //reference to the wrapped ExternalInterface Call var wrapped = extWrap(flashObjName, funcName, args); //only procede with ExternalInterface call if the global flashReady variable has been set if (flashReady) { wrapped(); } else { //queue the function so when flashReady() is called next, the function is called and the aruments are passed. extIntQueue.push(wrapped); } } //bundle ExtInt call and hold variables in a closure function extWrap(flashObjName, funcName, args) { //put vars in closure return function() { var funcCall = '$get("' + flashObjName + '").' + funcName; eval(funcCall).apply(this, args); } } I set the flashReady var to dirty whenever I update the Update Panel that contains the Flash (Flex) object. ScriptManager.RegisterClientScriptBlock(parentContainer, parentContainer.GetType(), "flashReady", "flashReady = false;", true); I'm pleased that I got it to work, but it feels like a hack. I am still on the learning curve with respect to concepts like closures why "eval()" is apparently evil, so I'm wondering if I'm violating some best practice or if this code should be improved, if so how? Thanks.

  • Foreign Key vs. Independent Relationships - is there improvement with Entity Framework 5?

    - by zam6ak
    I have read several articles and questions on concept of foreign key vs independent relationship when using Entity Framework. And I am still not 100% sure which way to go.... I would prefer not to "pollute" my domain POCOs by having a property that will be used in FK relationship when I already have a property reference to "has a" object. My questions are (looking at you @EFTeam, @Ladislav Mrnka) are there any improvements on this subject in the upcoming Entity Framework v5? are there more advantages if I use FK instead of independent associations (particularly with code first)?

  • How can an improvement to the query cache be tracked?

    - by Bill Paetzke
    I am parameterizing my web app's ad hoc sql. As a result, I expect the query plan cache to reduce in size and have a higher hit ratio. Perhaps even other important metrics will be improved. Could I use perfmon to track this? If so, what counters should I use? If not perfmon, how could I report on the impact of this change?

  • Tell me a Story

    - by Geoff N. Hiten
    I recently had a friend ask me to review his resume.  He is a very experienced DBA with excellent skills.  If I had an opening I would have hired him myself.  But not because of the resume.  I know his skill set and skill levels, but there is no way his standard resume can convey that.  A bare bones list of job titles and skills does not set you apart from your competition, nor does it convey whether you have junior or senior level skills and experience.  The solution is to not use the standard format. Tell me a story.  I want to know what you were responsible for.  Describe a tough project and how you saved time/money/personnel on that project.  Link your work activity to business value.  Drop some technical bits in there since we do work in a technical field, but show me what you can do to add value to my business well above what I would pay you.  That will get my attention. The resume exists for one primary and one secondary reason.  The primary reason is to get the interview.  A Resume won’t get you a job, so don’t expect it to.  The secondary reason is to give you and the interviewer a starting point for conversations.  If I can say “Tell me more about when….” and reference an item from your resume, then that is great for both of us.  Of course, you better be able to tell me more, both from the technical and the business side, at least if I am hiring a senior or higher level position.  As for the junior DBAs, go ahead and tell your story too.  Don’t worry about how simple or basic your projects or solutions seem.  It is how you solved the problem and what you learned that I am looking for.  If you learn rapidly and think like a DBA, I can work with that, regardless of you current skill level.

  • Stop applet execution on load, pause/resume using javascript?

    - by Zane
    I'm making something of a java applet gallery for my website (processing applets, if you're interested) and I'd like to keep the applets from running when the sit first loads. Then, when the appropriate button is clicked, a piece of javascript would tell the applet to continue execution until another button is pressed to stop it. I know that I can use appletName.start() and appletName.stop(), but it doesn't seem to work on load, at least not well. I'm using element.getElementsById( "applet" ) to get the applets to use the start and stop methods on. It slows Firefox to a crawl for some reason.
