  • How to override the behavior of Input type="file" Browse button?

    - by jay sean
    Hi All, I need to change the locale/language of the browse button in input type="file" We have a special function to change the locale of any text to the browser language such as en-US es-MX etc. Say changeLang("Test"); // This will display test in Spanish if the browser // locale is es-MX What I need to do is to change the language of the browse button. Since it is not displayed, I can't code it like changeLang("Browse..."); That's why I need to get the code of this input type and override so that I can apply my function to Browse text. It will be appreciated if you can give a solution for this. Thanks! Jay...

  • Trouble with authlogic_rpx

    - by Andrei
    Hi, I'm trying to run http://github.com/tardate/rails-authlogic-rpx-sample (only rails version was changed) but get error message http://gist.github.com/385696, when RPX returns information after successful authentication via Google Account. What is wrong here? And how I can fix it? The code was successfully tested with rails 2.3.3 by its author: http://rails-authlogic-rpx-sample.heroku.com/ I run on Windows with cygwin and rails (2.3.5), rpx_now (0.6.20), authlogic_rpx (1.1.1). Update In several hours RPX rejected my app http://img96.imageshack.us/img96/2508/14128362.png

  • How to create a delayed queue in RabbitMQ?

    - by eandersson
    What is the easiest way to create a delay (or parking) queue with Python, Pika and RabbitMQ? I have seen an similar questions, but none for Python. I find this an useful idea when designing applications, as it allows us to throttle messages that needs to be re-queued again. There are always the possibility that you will receive more messages than you can handle, maybe the HTTP server is slow, or the database is under too much stress. I also found it very useful when something went wrong in scenarios where there is a zero tolerance to losing messages, and while re-queuing messages that could not be handled may solve that. It can also cause problems where the message will be queued over and over again. Potentially causing performance issues, and log spam.

  • Website Sitemaps and <priority>, is it working?

    - by Mike Gleason jr Couturier
    Hi, My "Privacy Policy" page is seen more important by Google than other really more important pages on my website. I'm currently creating a script to generate a sitemap, should I bother with the priority? How do you effectively assign priorities to pages? I consider one of my page important but the page have less content than another one less important to my eyes... but maybe Google bot will see it the other way around. If my degree of "importantness" differs from the one of Google, will I get penalized on the ranking for a particular page? Thank you for sharing your black art with us :P

  • Sequence Diagram Reverse Engineering Tool?

    - by Wayne
    It's essential for me to find a tool that will reverse engineer sequence diagrams by integrating with the debugger. I suppose using the profiler could work also but less desirable. It's a key requirement that the tool in question will record all threads of execution since the app, TickZoom, is heavily parallelized. We just evaluated a most awesome tool from Sparx called Enterprise Architect which integrates with the debugger. It allows you to set a break point, start recording method traces from that break point. It's a lovely design and GUI. Hope it works for you but it only records a single thread of execution so that makes it unusable for us. I will put in a feature request to Sparx. But hope to find a similar tool that already does this since that's the only feature we need--not all the other amazing features that Sparx Enterprise Architect appears to do rather well.

  • How much more productive are three monitors than two?

    - by Sir Graystar
    I am mulling over whether to buy a new monitor, to go along side my current setup of two 24 (ish) inch monitors. What I want to know is whether this is worth the money (probably around £200)? I think most of us will agree that two monitors is much more productive than one when programming and developing (Jeff Atwood has said this many times on his blog, and I imagine that most of you are fans of his), but is three much more productive than two? What I'm worried about is that I will have so much space that one monitor will be used for things that are not related to the task (music, facebook etc.) and it will actually make me less productive.

  • IE z-index relative/absolute bug in list

    - by AJM
    I have the following navigation where .topNav has position:relative and subnav has position:absolute. I cant get the sublist to appear over the main list due to z-index problems. This seems to be a known problem. <ul> <li class="topNav">About Us <ul class="subNav"><li> Subsection A</li><li>Subsection B</li></ul> </li> </ul> Does anyone know of a workaround? UPDATE http://brh.numbera.com/experiments/ie7_tests/zindex.html shows exacly the problem I have. My original posting was in the context of a list but I have reduced the problem to the fact that z-index dosn't seem to work when have an element with position:absolute inside a parent element with position:relative

  • Specification, modeling and programming are principially the same, right?

    - by Gabriel Šcerbák
    In formal specifications based on abstract algebraic types and equational theory you use formulas of equational theory to specify theory. System which will satisfy those constraints is called in formal logic a model. Modeling is process of creating a model, which abstracts of some aspects, which are unnecessary details for a specific case. So concrete system has to adhere to created model in observed aspects. Programming is a process of creating a program which will have specific behaviour - will perform specific algorithms - and programming languages through different paradigms enable us to think in a certain specific way, which abstracts of some details, usually machine specific ones. So could we be doing all those things at the same time, because they are principially the same? Is declarative programming the nearest attempt to do that? Could we use some sort f programming languages which will be good for programming as well as for modeling and specification?

  • Drop a DB2 view if it exists...

    - by grenade
    Why doesn't this work in IBM Data Studio (Eclipse): IF EXISTS (SELECT 1 FROM SYSIBM.SYSVIEWS WHERE NAME = 'MYVIEW' AND CREATOR = 'MYSCHEMA') THEN DROP VIEW MYSCHEMA.MYVIEW; END IF; I have a feeling it has to do with statement terminators (;) but I can't find a syntax that works. Another similar question at http://stackoverflow.com/questions/355687/how-to-check-a-procedure-view-table-exists-or-not-before-dropping-it-in-db2-9-1 suggests that they had to create a proc but this isn't a solution for us.

  • Performance logging tips

    - by Germstorm
    I am developing large data collecting ASP.Net/Windows service application-pair that uses Microsoft SQL Server 2005 through LINQ2Sql. Performance is always the issue. Currently the application is divided into multiple larger processing parts, each logging the duration of their work. This is not detailed and does not help us with anything. It would be nice to have some database tables that contain statistics that the application itself collected from its own behavior. What logging tips and data structures do you recommend to spot the parts that cause performance problems?

  • Adding AllowPartiallyTrustedCallersAttribute To Paypal ASP.NET SDK

    - by snwr
    Currently, I cannot use Paypal Pro on my host (GoDaddy) because it requires Full trust level. After digging in Google, it seems a workaround is possible by adding AllowPartiallyTrustedCallersAttribute to the Paypal assembly. I have seen code samples that use AllowPartiallyTrustedCallersAttribute in their AssemblyInfo.cs file, however, I've yet to run into a code example that also happens to be using PayPal. My question is where should the AllowPartiallyTrustedCallersAttribute be added in my project if my objective is to make the PayPal assembly work? I have tried adding it to my AssemblyInfo.cs for the project that contains the entire website, but I have not been successful. At this point, any insight or shot in the dark would be greatly appreciated. Even if someone could point me in the general direction of some documentation I would be grateful. AllowPartiallyTrustedCallersAttribute Reference: http://msdn.microsoft.com/en-us/library/system.security.allowpartiallytrustedcallersattribute.aspx

  • Using TCP Acks to measure latency to a server?

    - by Ted Graham
    I am trying to measure latency to a server that I don't control. This is in a colocated environment, so the latency is on the order of 500 us (.5 ms). I understand that Cisco gear frequently deprioritizes ICMP traffic, making ping times unreliable. Is there a way for me to tell if this is the case on the gear I am traversing? Can I use TCP acknowledgements to determine the minimum latency to the remote server? To do this, I would somehow need to force the remote server to send a TCP ack immediately on receiving my data.

  • How to use ORDER BY, LOWER .. in SQL SERVER 2008 with non-unicode languages

    - by hgulyan
    Hi, The question is about Armenian. I'm using sql server 2005, collation SQL_Latin1_General_CP1_CI_AS, data mostly is in Armenian and we can't use unicode. I tested on ms sql 2008 with a windows collation for armenian language ( Cyrillic_General_100_ ), I have found here, ( http://msdn.microsoft.com/en-us/library/ms188046.aspx ) but it didn't help. I have a function, that orders hex values and lower function, which takes each char in string and covnerts it to it's lower form, but it's not acceptable solution, it works really slow, calling that functions on every column of a huge table. Is there any solution for this issue not using unicode and working with hex values manually?

  • Hudson build defaults

    - by toluju
    This has been a fairly long-standing problem for us with our Hudson installation, and searching around the Hudson Wiki / Issue Tracker hasn't yielded any insight to this. The question: Is it possible to set certain default values for a maven2 build in Hudson? For example, we want all our projects to run the "clean" goal before a build, we want all our builds to poll the SCM hourly, and we want all our builds to deploy to our maven repository on build success. Right now, we have to manually set these setting for every project individually, which can be rather time consuming as we have 30+ different projects all being managed by Hudson. This is especially annoying if we need to change a particular setting that will affect all projects (e.g. change the repository URL). Given that I couldn't find any mention of this on the Wiki or Issue Tracker leads me to believe that I'm missing something obvious, but I cannot find an answer on my own.

  • ResourceManager and not supported platform

    - by wince
    I use ResourceManager for UI localization of my WinCE 5 software. I have some resource files with text strings on different languages Resourse.resx Resourse.de-DE.resx Resourse.ru-RU.resx When I want to display UI in English I call: Resourse.Culture = new CultureInfo("en-US"); label1.Text = Resourse.LabelText; in German: Resourse.Culture = new CultureInfo("de-DE"); label1.Text = Resourse.LabelText; in Russian: Resourse.Culture = new CultureInfo("ru-RU"); label1.Text = Resourse.LabelText; but here I get PlatformNotSupportedException. I know that my WinCE does not contain Russian and I cannot modify OS to appened this, so my question is how I can say to ResourceManger to use Resourse.ru-RU.resx when I set Culture = new CultureInfo("ru-RU") ?

  • Development team collaboration via Google Wave

    - by Alex N.
    I hope I am not repeating any previously asked question. Anyway, so Google Wave is nice and shiny and sounds like a lot of folks(at least at Google I/O :) used it in a useful for work(!) way. I've been beta-testing Google Wave for sometime now, but can't quite grasp how to improve our workflow using it. We have a medium size team of developers that are spread out around US and Europe and naturally most of communication is happening via IM and Skype and email of course. So what are specific things that could be offloaded to Google Wave to improve collaboration by leaps and bounds(meaning not just replacing IM with nicer IM)?

  • How to properly update a feature branch from trunk?

    - by Pavel Radzivilovsky
    SVN book says: ...Another way of thinking about this pattern is that your weekly sync of trunk to branch is analogous to running svn update in a working copy, while the final merge step is analogous to running svn commit from a working copy I find this approach very unpractical in large developments, for several reasons, mostly related to reintegration step. From SVN v1.5, merging is done rev-by-rev. Cherry-picking the areas to be merged would cause us to resolve the trunk-branch conflicts twice (one when merging trunk revisions to the FB, and once more when merging back). Repository size: trunk changes might be significant for a large code base, and copying the differences files (unlike SVN copy) from trunk elsewhere may be a significant overhead. Instead, we do what we call "re-branching". In this case, when a significant chunk of trunk changes is needed, a new feature branch is opened from current trunk, and the merge is always downward (Feature branches - trunk - stable branches). This does not go along SVN book guidelines and developers see it as extra pain. How do you handle this situation?

  • Is there a config option in PHP to prevent undefined constants from being interpreted as strings?

    - by mrbinky3000
    This is from the php manual: http://us.php.net/manual/en/language.constants.syntax.php If you use an undefined constant, PHP assumes that you mean the name of the constant itself, just as if you called it as a string (CONSTANT vs "CONSTANT"). An error of level E_NOTICE will be issued when this happens. I really don't like this behavior. If I have failed to define a required constant, I would rather the script fail so that I am forced define it. Is there any way to force PHP to crash the script if it tries to use an undefined constant? For example. Both of these scripts do the same thing. <?php define('DEBUG',1); if (DEBUG) echo('Yo!'); ?> and <?php if(DEBUG) echo('Yo!'); ?> I would rather the second script DIE and declare that it tried to use an undefined constant DEBUG.

  • Oracle - Parameterized Query has EXECUTIONS = PARSE_CALLS

    - by Cory Grimster
    We have a .NET application talking to Oracle 10g. Our DBA recently pulled a list of queries where executions is equal to parse_calls. We assumed that this would help us find all of the unparameterized queries in our code. Unexpectedly, the following query showed up near the top of this list, with 1,436,169 executions and 1,436,151 parses: SELECT bar.foocolumn FROM bartable bar, baztable baz WHERE bar.some_id = :someId AND baz.another_id = :anotherId AND baz.some_date BETWEEN bar.start_date AND (nvl(bar.end_date, baz.some_date + (1/84600)) - (1/84600)) Why is executions equal to parse_calls for this query?

  • How would you communicate with aliens as a computer scientist?

    - by Pyrolistical
    Let's say aliens arrive on Earth and instead of just sending mathematicians and linguistic experts governments around the work decide to send an expert of major field. After a quick round of sorting you are paired up with an alien computer scientist. Given you don't understand each others language how would you using computer science to start the ground work of communication? eg. We know binary is universal, but not the way we write it. The symbols are not universal nor is the the direction we write it (MSB vs LSB and left vs right) Assume aliens are "similar" to us physically it won't impede visual communication.

  • Is bundler ready for prime time?

    - by schof
    I'm considering using bundler for deploying a Spree app on Heroku. My question is, is bundler ready for prime time? I know there are some rough edges but I guess I'd like to know more about what the current limitations are and figure out if this is an option for us. Specifically, I'd like to do the git repository stuff git "git://github.com/indirect/rails3-generators.git" gem "rails3-generator Does anyone want to encourage/discourage me from this course of action? Anybody have experience with this on Heroku in particular?

  • How to solve such system with given parts of it? (maple)

    - by Kabumbus
    So I had a system #for given koefs k:=3; n:=3; #let us solve system: koefSolution:= solve({ sum(a[i], i = 0 .. k) = 0, sum(a[i], i = 0 .. k)-(sum(b[i], i = 0 .. k)) = 0, sum(i^n*a[i], i = 0 .. k)-(sum(i^(n-1)*b[i], i = 0 .. k)) = 0 }); So I have a vector like koefSolution := { a[0] = 7*a[2]+26*a[3]-b[1]-4*b[2]-9*b[3], a[1] = -8*a[2]-27*a[3]+b[1]+4*b[2]+9*b[3], a[2] = a[2], a[3] = a[3], b[0] = -b[1]-b[2]-b[3], b[1] = b[1], b[2] = b[2], b[3] = b[3]} I have a[0] so I try solve({koefSolution, a[0] = 1}); why it does not solve my system for given a[0]? ( main point here is to fill koefSolution with given a[] and b[] and optimize.)

  • Using Unix Process Controll Methods in Ruby

    - by John F. Miller
    Ryan Tomayko touched off quite a fire storm with this post about using Unix process control commands. We should be doing more of this. A lot more of this. I'm talking about fork(2), execve(2), pipe(2), socketpair(2), select(2), kill(2), sigaction(2), and so on and so forth. These are our friends. They want so badly just to help us. I have a bit of code (a delayed_job clone for DataMapper that I think would fit right in with this, but I'm not clear on how to take advantage of the listed commands. Any Ideas on how to improve this code? def start say "*** Starting job worker #{@name}" t = Thread.new do loop do delay = Update.work_off(self) break if $exit sleep delay break if $exit end clear_locks end trap('TERM') { terminate_with t } trap('INT') { terminate_with t } trap('USR1') do say "Wakeup Signal Caught" t.run end end
