  • Help! I got a runaway PHP script. My server is down.

    - by gAMBOOKa
    I got a PHP script that is looping and will continue to do so for about another hour. How do I stop it. The script explicitly overrides the time out and the memory buffer. It's on a shared hosting server with cPanel installed. The entire website is down until the script completes. I had added a usleep(100000) statement, but it doesn't appear to work.

  • Optimum size of transaction in Postgres?

    - by Joe
    I'm running a process that does a lot of updates ( 100,000) to a table. I have the choice between putting all the updates in a single transaction or committing transactions every 1000 or so. Ignore for the moment the case where a transaction fails and is aborted. I'm interested in the best size of transaction for memory and speed efficiency.

  • SQL Server, Remote Stored Procedure, and DTC Transactions

    - by marc
    Our organization has a lot of its essential data in a mainframe Adabas database. We have ODBC access to this data and from C# have queried/updated it successfully using ODBC/Natural "stored procedures". What we'd like to be able to do now is to query a mainframe table from within SQL Server 2005 stored procs, dump the results into a table variable, massage it, and join the result with native SQL data as a result set. The execution of the Natural proc from SQL works fine when we're just selecting it; however, when we insert the result into a table variable SQL seems to be starting a distributed transaction that in turn seems to be wreaking havoc with our connections. Given that we're not performing updates, is it possible to turn off this DTC-escalation behavior? Any tips on getting DTC set up properly to talk to DataDirect's (formerly Neon Systems) Shadow ODBC driver?

  • What CPAN module can summarize arbitrary error logs?

    - by mithaldu
    I'm maintaining some website code that will soon dump all its errors and warnings into a log file. In order to make this a bit more pro-active I plan to parse this log file daily, summarize the warnings and errors (i.e. count the occurrence of each specific one and group by either warning/error) and then email this to the devs on the project. This would likely admittedly be rather trivial with a hash and some further fiddling, I wondered if there is a suitable module on CPAN that I could use to do this task. It would either be one that summarizes specifically Perl error/warnings logs or one that summarizes arbitrary text files. Any suggestions?

  • FastMM and Dynamically loaded DLLs

    - by Vegar
    I have a host application, that loads a dozen of libraries at start up. I want to switch from Delphi 7s default memory manager to the full version of FastMM4 for better mem leak reporting. Should I include FastMM4 in the uses section of both the host application and the libraries? What about shared runtime packages? -Vegar

  • Dropping PendingIntents

    - by Jeremy Edwards
    Is it ok to drop PendingIntents in android if they are never used. Such as in an AppWidgetProvider where a PendingIntent that was never used be overwritten by a new PendingIntent. Or should we call cancel on all unused PendingIntents to clean up memory appropriately?

  • Is there something like the OllyDbg / SoftICE disassembler + debugger for java?

    - by Ran Biron
    Is there a utility similar to OllyDbg / SoftICE for java? I.e. execute class (from jar / with class path) and, without source code, show the disassembly of the intermediate code with ability to step through / step over / search for references / edit specific intermediate code in memory / apply edit to file... If not, is it even possible to write something like this (assuming we're willing to live without hotspot for the debug duration)?

  • Syncronize an SVN repo (svnsync) with encoding errors

    - by Hamish
    Is it possible to fix/bypass non-UTF8 encoded svn:log records when syncronizing repositories with svnsync? Background I'm in the process of taking over the maintenance of an open source module that is stored within a large (well over 10,000 revisions) subversion (1.5.5) repository. I do not have admin access to the remote repository to dump/filter/load the module. The old repository is being discontinued and I am trying to sync the original sub module to my local (1.6+) repository with svnsync. For example: svnsync file://home/svn/temp-repo/ http://path.to.repo/modulename/ The problem is that the old repository didn't enforce UTF8 encoding and I'm hitting errors like: svnsync: Cannot accept 'svn:log' property because it is not encoded in UTF-8 I can't modify the log property in the source repository so I need to somehow modify or ignore the property value when the encoding is unknown/invalid. Any ideas? For example, is it possible to write a pre-revprop-change script to modify the log property in transit?

  • Why do I need to call new?

    - by cam
    It seems like I could program something without ever using the word 'new', and I would never have to worry about deleting anything either. From what I understand, it's because I would run out of stack memory. Is this correct? I guess my main question is, when should I call 'new'?

  • Avoid writing SQL queries altogether in SSIS

    - by Jonn
    Working on a Data Warehouse project, the guy that gave us the tutorial advised that we stick to using SQL queries over defining a lot of data flow transformations, citing points like it'll consume a lot of memory on the ETL box so we'd rather leave the processing to the DB box. Is this really advisable? Where's the balance between relying on GUI tools over executing a bunch of SQL scripts on your Integration package? And honestly, I'd like to avoid writing SQL queries as much as I can.

  • Why should i use EJB?

    - by Nitesh Panchal
    Hello, As we all know that EJB's in 3.1 or 3.0 are simple POJOs. You just need to give annotations here and there and it gets converted to EJB from simple class. So, now my question is why should i use EJBs at all? Can i not do without them? In .Net i created class library and got things done. I never felt the need for anything like EJB. Simple classes were enough. Then, why in Java people stress on EJB? What is difference between a simple POJO and EJB in terms of execution and memory? Further which function should i write in EJB and which should i write in simple class? Should i dump every function in EJB only? or there is some kind of strategy? Does EJB provide anything special?

  • What is the need of collection framework in java?

    - by JavaUser
    Hi, What is the need of Collection framework in Java since all the data operations(sorting/adding/deleting) are possible with Arrays and moreover array is suitable for memory consumption and performance is also better compared with Collections. Can anyone point me a real time data oriented example which shows the difference in both(array/Collections) of these implementations. Thx

  • how to get the camera data

    - by beof
    Hello ,guys, My app needs to get the camera data from Iphone. In my ImagePickerController, there is overlayView drawing realtime indications. I use UIGetScreenImage() to get the screenshot, and I also dump overlayview to image, then I can restore the original Image based on these two images. if the overlayView is still, it works quite well, but if the overlayView keeps changing, UIGetScreenImage() can not keep up with it. For example,if the overlayView changes from a rectangle to a circle, then calling UIGetScreenImage() returns with a rectangle on top of it. Is there a way to get the realtime camera data? I really appreciate if someone could help.

  • graph algorithms on GPU

    - by scatman
    the current GPU threads are somehow limited (memory limit, limit of data structures, no recursion...). do you think it would be feasible to implement a graph theory problem on GPU. for example vertex cover? dominating set? independent set? max clique?.... is it also feasible to have branch-and-bound algorithms on GPUs? Recursive backtracking?

  • Is It Possible to get a (rough) Mobile Phone Location from a HTTP Request

    - by Tim Lytle
    If memory serves me correctly, google does this for the maps site. I know google's mobile maps app can determine the rough location (I assume using some kind of cell tower lookup), yet I seem to remember the site getting somewhat close to the current location when viewing on a mobile browser. Anyone know how/if that's possible? Does the IP address change based on the tower or area (seems like they'd be using some kind of gateway common to the carrier)?

  • Several ifstream vs. ifstream + constant seeking

    - by SpyBot
    I'm writing an external merge sort. It works like that: read k chunks from big file, sort them in memory, perform k-way merge, done. So I need to sequentially read from different portions of the file during the k-way merge phase. What's the best way to do that: several ifstreams or one ifstream and seeking? Also, is there a library for easy async IO?

  • How do you use technology to memorize set of terms?

    - by user49767
    Always there are few set of items needs to be memorized in short span of time. Here are my following cases. 1) My Job requires some set of items needs to be memorized. 2) I am a developer who has to learn 150+ tags within next 3 days. 3) Fix developer/support has to remember minimum of 125+ tags (set of possible values). 4) It is better if team's SQL developer knows all the table and columns in my database. 5) When guys join new department or job. Memorizing few related items will definitely gives some benefit. Most of the cases, I suggest people to understand the domain better and nothing wrong in using google (but remember correct search-word). But recently I came across a junior developer who took lot of effort in memorizing set of things (150+ table structures, fix protocol tags, almost 300+ configuration items from property file) and was very very successful in his job and was swift in responding for support queries. Needless to say he is smart worker too (not a dumb guy). When I try to recollect some of the successful employees I met, they were so good in remembering entire schema and they did in short span of time. But I don't argue that memorizing alone gives success, but it greatly helps when situation demands. Here my question is, I am not good at remembering things, but it shouldn't be lame excuse. Hence I am evaluating using technolgies better to memorize set of items. Not very much interested in memory techniques (mnemoninc, photography memory, etc..). Even I have recorded 100+ items and listen to that whenever I found free time, defintely there were some fruitful result. Now I need your suggestion about what are all the ways to exploit technology to memorize. There could be so many reason why guys remember a subject (passionate, essential, author, creator, responsbile). Not interested in dissecting why guys remeber. Rather much interested in using ways, and techniques (cheat sheet...) to remember a set of itmes. Note : I appreciate, encourage people who could rephrase my question better. Note : I have kept couple of cheat-sheet close to my monitor, honestly it did not help me :).

  • Arraylist as repeater datasource (how to access from .aspx)

    - by Phil
    I have an arraylist: Dim downloadsarray As New ArrayList downloadsarray.Add(iconlink) downloadsarray.Add(imgpath) downloadsarray.Add(filesize) downloadsarray.Add(description) Which is the datasource of my repeater: DownloadsRepeater.DataSource = downloadsarray DownloadsRepeater.DataBind() Please can you tell me how I output the items in the array to the .aspx page. I usually use (when using sqldatareader as datasource): <%#Container.DataItem("1stcolumnnamestring")%> <%#Container.DataItem("2ndcolumnnamestring")%> But this does not work when using the arraylist as datasource. Thanks. ps... I know how to use <%#Container.DataItem% to dump everything but I need to get at the items in the array individually, not have them all ditched out to the page in one go. For example, item 1 contains a link, item 2 contains an image path, item 3 contains a description. I need to have them kick out in the correct order to build the link and icon correctly.

  • Alternative databases to use when putting IIS Logs into a database using LogParser

    - by Robin Day
    We have run some scripts that use LogParser to dump our IIS logs into a SQL Server database. We can then query this to get simple stats on hits, usage etc. It's also good when linking it to error log databases and performance counter database to compare usage with errors, etc. Having implemented this for just one system and for the last 2-3 weeks we already have a 5GB database with around 10 million records. This is making any queries to this database quite slow and will no doubt cause storage issues if we continue to log as we are. Can anyone suggest any alternative databases that we could use for this data that would be more efficient for such logs? I'd be particularly interested in any experience of Google's BigTable or Amazon's SimbleDB. Are either of these suitable for reporting queries? COUNTs, GROUP BYs, PIVOTs?
