  • Creating files on a time (hourly) basis

    - by Yaniv
    Hi there, I experimenting with twitter streaming API, I use Phirehose to connect to twitter and fetch the data but having problems storing it in files for further processing. Basically what I want to do is to create a file named date("YmdH")."."txt" for every hour of connection. Here is how my code looks like right now (not handling the hourly change of files) public function enqueueStatus($status) $data = json_decode($status,true); if(isset($data['text'])/*more conditions here*/) { $fp = fopen("/tmp/$time.txt"); fwirte ($status,$fp); fclose($fp); } Help is as always much appreciated :)

  • Working with Foreign languages

    - by Matt
    My DB needs to hold strings containing foreign language characters such that; User enters string into form, form submitted and string added to DB, string will be displayed on page for viewing. I would like to use UTF8 as this will be able to handle all of the required languages. Currently I believe my DB is set to 'latin1' but webpages are capable of displaying correct charachters anyways. Problems arise when trying to set textareas to hold foreign charachters and when viewing DB via command-line. How can I implement this most effectively? My plan was to blitz the whole site such that:DB Charset is UTF8 and web pages charset is UTF8. Could someone give me the minimal commands on how to do this so I don't end up duplicating things (Having "UTF8" commands everywhere when I really just need one) and making things too difficult to control. Newbie Thanks

  • Delay and Inconsistent results using Twitter search API when using "since_id" parameter.

    - by benr
    Hi. We've noticed what seems to be a delay and/or inconsistent results using the Twitter Search API when specifying a sinceid in the param clause. For example: http://search.twitter.com/search?ors=%23b4esummit+@b4esummit+b4esummit&q=&result_type=recent&rpp=100&show_user=true&since_id= Will give the most recent Tweets, but: http://search.twitter.com/search?ors=%23b4esummit+@b4esummit+b4esummit&q=&result_type=recent&rpp=100&show_user=true&since_id= 12642940173 will often not give tweets that are after that ID for several hours (even though they're visible in the first query)... anyone have similar problems?

  • iphone best practice, how to load multiple high quality images

    - by bennythemink
    Hi guys and girls, I have about 20-ish high quality images (~3840x5800 px) that I need to load in a simple gallery type app. The user clicks a button and the next image is loaded into the UIImageView. I currently use [UIImage imageWithContentsOfFile:] which takes about 6 seconds to load each image in the simulator :( if I use [UIImage imageNamed:] it takes even longer to load but caches the images which means its quicker if the user wishes to see the same images again. But it may cause memory problems later with all that caching crashing my app. I want to know whats the best practice for loading these? I'm experimenting with reducing image file size as much as is possible but I really need them to be high quality image for the purpose of the app (zoomable, etc.). Thanks for any advice

  • LINQ Changeset multi-threading

    - by Xodarap
    I'm using LINQ to SQL and after I submit some changes I want to spawn a thread which looks through all the changes and updates our lucene index as necessary. My code looks vaguely like: (new Thread(() => { UpdateIndex(context.GetChangeSet()); }).Start(); Sometimes though I get an InvalidOperationException, which I think is because context.GetChangeSet() is not thread-safe, and so if the change set is modified in one thread while another thread is enumerating through it, problems arise. Is there a "thread-safe" version of GetChangeSet()? Or some way I can do ChangeSet.clone() or something?

  • Show parts of the result of an SQL statement using PHP

    - by mouthpiec
    I have an SQL query which returns a set of data (around 40-50 tuples). I would like to display the results 5 at a time on an HTML page using PHP. I already managed to have the right SELECT statement, but i am having problems to display the results 5 by 5 using a "more" button. Can you please help? Note that every time i call the query, the data is being randomized, so it is not possible to set limits and call the query again. I have to find the method to store the results somewhere, and then show them 5 by 5.

  • Write a row to Google Spreadsheet programmically javascript

    - by Verber
    I'm trying to find a way to insert a row into a google spreadsheet dynamically. I have a list of objects that has all the data for every column in a row. I'm just trying to run a for loop and then send the data to the row in the spread sheet. But the spreadsheet is completely empty. So I don't know if that creates certain problems or not. for(var j=0; j < masterList.length; j++) { //tried this one but it didn't pan out sheet.appendRow([ masterList[j].Date, masterList[j].Name, masterList[j].Bugs, masterList[j].Enhancements, masterList[j].Epic, masterList[j].DevOps, masterList[j].High ]); }

  • MySQL does not work on localhost without Local Area Connection

    - by user985171
    I use WampServer(Apache, PHP, MySQL) and have no problems when some kind of network adapter(wireless or lan) is connected(i-e Local Area Connection has status connected) 'even if i am not connected to the internet'(for example when i am connected to the router but that is not connected to the internet). When there is no network connection, i get a php error like MySQL could not connect to 127.0.0.1 on port 3306. Interestingly, 'telnet 127.0.0.1 3306' says that it could not connect to the port, even when the server and MySQL are running fine(i-e when some kind of local area connection is connected). So i turned off all kinds of firewall(antivirus and windows) but still no difference in anything. And that is why this issue is quite puzzling. Things i have already tried(will update this list along the way):- -The skip-networking directive in my.ini.

  • How to identify deadlock conditions in a third-party application?

    - by Imhotep is Invisible
    I am using a third-party application to handle batch CD audio extraction via multiple FireWire attached devices, but the application frequently (though non-deterministically) hangs during the extraction. I suspect that the multithreaded application is deadlocking over some shared resource. The developer, however, suspects the problem lies elsewhere but is not addressing the problem at this time. I would like to be able to do some legwork on my end to a) prove the condition exists and b) ideally point him in the right direction. The problems: while I used to be a programmer, it's been awhile and I need to shake off the dust (last work I did was back in '99 and it was under Solaris, while the application runs under XP). Rather than there being a dearth of information online, there's almost too much to digest. Are there any suggested guides or tutorials that might help me get back up to speed sufficient enough to help identify and/or diagnose the deadlock, or are there tools or approaches that I should study up on to aid me in my task? Many thanks for all suggestions!

  • IE issues with drag/drop (script.aculo.us)

    - by deb
    I have a page with a left and a right div. Inside each of these there are several divs. I can drag&drop them inside the left/right divs or move from one to the other So the page is something like ........ ........ ........ ........ I am using scriptaculous and prototype for the drag&drop If I drag in Firefox things work fine. In IE6-IE8 however I have 2 problems: 1) When I drag from left to right or the other way around, the inner divs do not keep their relative distances: the div I moved now overlaps with the div on the opposite side (if I do a reload of the page the divs are set correctly again) 2) If I shrink the window width below a certain width the divs either on the left or the right droppable disappear. Any ideas? deb

  • Java sockets: can I write a TCP server with one thread?

    - by hmp
    From what I read about Java NIO and non-blocking [Server]SocketChannels, it should be possible to write a TCP server that sustains several connections using only one thread - I'd make a Selector that waits for all relevant channels in the server's loop. Is that right, or am I missing some important detail? What problems can I encounter? (Background: The TCP communication would be for a small multiplayer game, so max. 10-20 simultaneous connections. Messages will be sent about every few seconds.)

  • Why is this javascript function so slow on Firefox?

    - by macrael
    This function was adapted from the website: http://eriwen.com/javascript/measure-ems-for-layout/ function getEmSize(el) { var tempDiv = document.createElement("div"); tempDiv.style.height = "1em"; el.appendChild(tempDiv); var emSize = tempDiv.offsetHeight; el.removeChild(tempDiv); return emSize; } I am running this function as part of another function on window.resize, and it is causing performance problems on Firefox 3.6 that do not exist on current Safari or Chrome. Firefox's profiler says I'm spending the most time in this function and I'm curious as to why that is. Is there a way to get the em size in javascript without doing all this work? I would like to recalculate the size on resize incase the user has changed it.

  • Looking for a good course/book/resource on modern databases

    - by spanky
    This is slightly embarrassing. I'm a professional developer working at one of the big tech companies and I've never used a database. I've got an idea for a website I want to build as a learning experience and possibly as a business, but I don't have the faintest idea what database to use, let alone how to fix/debug the database when I run into problems. I'm looking for a course, a website, a book, etc., that will give me an overview of modern database technology (SQL vs. NOSQL vs. relational vs. non-relational (I only have a vague idea what these even mean)). I'm starting by googling/wikipediaing all of these terms, but if there are better, comprehensive resources available that I should be aware of, I'd love to hear about them.

  • MySQL - Counting rows in preparation for greatest-n-per-group not working?

    - by John M
    Referring to SO and other sites have given me examples of how to use MySQL to create a 'greatest-n-per-group' query. My variant on this would be to have a query that returns the first 3 rows of each category. As the basis for this I need to sort my data into a usable sequence and that is where my problems start. Running just the sequence query with row numbering shows that changes in category are mostly ignored. I should have 35 categories returning rows but only 5 do so. My query: set @c:=0; set @a:=0; SELECT IF(@c = tdg, @a:=@a+1, @a:=1) AS rownum, (@c:=tdg) , julian_day, sequence, complete, year, tdg FROM tsd WHERE complete = 0 order by tdg, year, julian_day, sequence Do I have a syntax mistake with this query?

  • Creating objects and referencing before saving object to db

    - by Flexo
    Sorry about the vague title, but i didnt know how to ask the question in one line :) I have an order with nested itemgroups that again have nested items. the user specify the amount of item that he would like to have in each itemgroup. I would like to create these items in the create method of the orders controller when the order itself is being created. I kinda have 2 problems here. First, how do i set the reference of the items, or better yet, put the items into the @order object so they are saved when the @order is saved? the items are being stored in the db as the code is now, but the reference is not set because the order is not stored in the db yet so it doesnt have an id yet. Second, im not sure im using the correct way to get the id from my itemgroup. @order = Order.new(params[:order]) @order.itemgroups.each do |f| f.amount.times do @item = Item.new() @item.itemgroup_id = f.id @item.save end end

  • Identifying control characters in Perl

    - by sganesh
    Actually, I am doing one project. In that I want to implement the command line features as like in linux terminal. And I saw this in ftp command also. If I press tab I need to list the commands. If I press control characters I need to get that characters based on that I will do some action. And If I give any commands it should execute. For this I tried with Term::ReadKey that is non canonical mode. But here I am facing more problems like, If I press any control character or arrow I got three characters. Ex: for up arrow I got ascii as 279165. Can anyone help me out of this problem? And I feel that there will be a better solution for this. Thanks in Advance.

  • Advantages of GitHub over Bitbucket for Git Repositories [closed]

    - by rolve
    Now that Bitbucket also supports Git repositories, it seams to me that it is a good alternative to GitHub, especially since its free plan includes unlimited private repositories, which is not available on GitHub. Yet, GitHub seams much more popular. Are there any major reasons to choose GitHub as the hosting site for Git repositories instead of Bitbucket? (Although I have no problems with making my personal projects publicly available in general, I like the idea of being able to make the switch from public to private or vice versa any time I want. But if there are some good reasons to use GitHub, I would be willing to give up this freedom.)

  • iPhone "multi-threading" question

    - by MrDatabase
    I have a simple iPhone game consisting of two "threads": the main game loop where all updating and rendering happen 30 times per second (NSTimer)... and the "thread" that calls the accelerometer delegate 100 times per second. I have a variable "xPosition" that's updated in the accelerometer delegate function and used in the game loop. Is there a possibility of the two "threads" trying to use xPosition at the same time (hence causing a crash or some other problem). If so how can I fix this w/ minimal impact to the game's performance? I've been using this set-up for many months of development and incremental testing and I've never run into any problems. Cheers!

  • How do I modify a string printed by a script?

    - by Liso22
    I'm having problems with wordpress mishandling accented characters, or maybe the problem is with some plugin. Whichever the case I need to "translate" some strings, removing accents which i do with: $value = strtr($value, $trans); I really need to change this string which renders the user's location but it's printed with a script so I have no idea how to do it: <script language="javascript"> document.write('' + geoip_city() +''); </script> Is there a way to assign it's result to a php value beforehand or something? Maybe removing the accents with a script. I really need to modify it, how could I manage to do it? Thanks

  • Passing URIs as URL arguments in Drupal 6

    - by wynz
    I'm running into problems trying to pass absolute URIs as parameters with clean URLs enabled. I've got hook_menu() set up like this: function mymodule_menu() { return array( 'page/%' = array( 'title' = 'DBpedia Display Test', 'page callback' = 'mymodule_dbpedia_display', 'page arguments' = array(1), ), ); } and in the page callback: function mymodule_dbpedia_display($uri) { // Make an HTTP request for this URI // and then render some things return $output; } What I'm hoping to do is somehow pass full URIs (e.g. "http://dbpedia.org/resource/Coffee") to my page callback. I've tried a few things and nothing's worked so far... http://mysite.com/page/http%3A%2F%2Fdbpedia.org%2Fresource%2FCoffee Completely breaks Drupal's rewriting http://mysite.com/page/?uri=http%3A%2F%2Fdbpedia.org%2Fresource%2FCoffee Gives a 404 http://mysite.com/page/http://dbpedia.org/resource/Coffee Returns just "http:", which makes sense I could probably use $_GET to pull out the whole query string, but I guess I'm hoping for a more 'Drupal' solution. Any suggestions?

  • What is the difference between panic and an assert?

    - by acidzombie24
    Go doesn't provide assertions. They are undeniably convenient, but our experience has been that programmers use them as a crutch to avoid thinking about proper error handling and reporting. However it has print and println which does panic like print, aborts execution after printing panicln like println, aborts execution after printing Isnt that the same thing as an assert? Why would they claim the above but have panic? i can see it leading to the same problems but adding an error msg to the end of it which can easily be abused. Am i missing something?

  • Date or String declaration in a javabean

    - by Jeff
    Should I declare an attribute in a javabean that holds a date value a user types in on an HTML form as a String or Date? I feel I should declare as a Date, however, since I do server validation on all form data, if the date doesn't validate, when I pass the form bean back to the jsp view for correcting, I lose the date value that the user tried to type in. If I declare as a String, if the date doesn't validate, I'm able to set the string value in the bean and pass the bean back to the view and the user can see what they incorrectly typed. But with a String declaration for Date inputs I forsee problems down the road with my DAO. I want to be able to use a DAO utility which generates a prepare statement using setObject. In my html form I request dates to be mm/dd/yyyy and in DAO i'm using Oracle Date. I can not use hibernate or such, since this is a corporate intranet. What is the best practice "pattern" I should be following??

  • Best memory settings for eclipse 4.2 (STS 3.1) on Windows 7 64 bit?

    - by jorrebor
    I apoligize in advance if this question is indeed too subjective as SO warns me. My workstation has 8 gb of ram and runs windows 7 64 bit. I use the Spring tool Suite (3.1) but as soon as i am starting to open and modify the spring config (.xml) files, STS becomes incredibly slow. I already tried switching off "build automatically" and to increase memory settings but no luck. How should i change my .ini ? this is what i have set now: -vm C:/Program Files/Java/jdk1.7.0_07/bin/javaw.exe -startup plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar --launcher.library plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20120522-1813 -product org.springsource.sts.ide --launcher.defaultAction openFile --launcher.XXMaxPermSize 4096M -vmargs -Dosgi.requiredJavaVersion=1.5 -Xms512m -Xmx2048m -XX:MaxPermSize=512m My collageu running the same project in IntelliJ, has no problems.

  • On Linux do people chroot a Java Web Application or use IPTables and run as non-root?

    - by Adam Gent
    When you run a Java Servlet Container that you would like to serve both static and dynamic content on port 80 you have the classic question of whether to run the server as: As root in hopefully a chroot jail if you can (haven't gotten this working yet) As a non root user and then use IPTables to forward port 80 to some other port (1024) that the container is running on Both: As a non root user, IPTables, and chroot jail. The problem with opt. 1 is the complexity of chrooting and still the security problems of running root.The problem with opt. 2 is that each Linux distro has a different way of persisting IPTables. Option 3 of course is probably idea but very hard to setup. Finally every distro has the annoying differences in daemon scripts. What do people find as the best distro agnostic solution and are there resources to show how to do this?
