  • Microsoft Mouse and Keyboard Center - Slow response for App-specific shortcuts

    - by Darrel Hoffman
    So a few months ago, I bought a new MS mouse, and was surprised that they'd discontinued Intellipoint in favor of this Microsoft Mouse and Keyboard Center. It seems to have the same functionality underneath all the bloat, but there's a very serious drawback - when I set up application-specific functions for the extra buttons on the mouse, they work, but sometimes with a very long delay, like up to a minute or more. For example, I often set up the left side button as an "Undo" in various programs for convenience. But sometimes, when I try to use that Undo button, nothing happens, so I'm forced to use the standard Ctrl-Z or whatever. But then, a minute or so later, it suddenly remembers that I hit that button a while back, and calls the Undo unexpectedly on something entirely different. It's infuriating. No modern computer function should be this slow. It's not the software or the computer itself, because doing an Undo via Ctrl-Z or the menu still works instantly. It's very definitely a side-effect of delayed response to the mouse button. Usually after it delays the first time, it'll work quickly after that, but if you haven't used a given shortcut in several minutes, it "forgets" again and you get another inexplicably long delay. Intellipoint never had this problem, but it's not supported any more, and not compatible with the newer mice. Has anyone else noticed slow-downs with MS M&K C and app-specific shortcuts? Any ideas how to get around this? I use these shortcuts extensively in my workflow and it's just entirely unacceptable to have such a long delay in what should be a pretty basic feature.

  • PHP 5.2 et 5.3 : un bug étrange rend les attaques par Déni de Service enfantine sous Windows et Linux

    PHP : un bug étrange rendrait enfantines les attaques par Déni de Service Il toucherait les versions 5.2 et 5.3 du langage sous Windows et Linux Un bug critique vient d'être découvert dans les branches 5.2 et 5.3 de PHP, le langage de programmation Web parmi les plus populaires. Ce bug est provoqué par certaines valeurs de chiffres à virgule flottante ayant un nombre considérable de décimaux. Leurs calculs ou évaluations en PHP provoqueraient une boucle infinie occupant 100% des ressources du CPU. L'exécution de la ligne de code suivante, ou même son équivalent sans la notation scientifique (avec 324 décimales), provoquerait donc le plantage de la machine, et ce sou...

  • memory and time intensive php task

    - by Goddard
    Sorry if this question has been asked before, but I couldn't find anything usable. I'm working on a project for a client and currently I have to loop through the users table which is about 3000 records and still growing. I have to do some calculations on a nightly basis which I am going to be using cron/php. The calculations script uses about 3.5mb of memory and takes about 1 second to run. When loading individual users my current php setup handles this fine, but if I try and loop through the user list my php script execution time runs out. I've read after doing some searching that I can make the page reload itself after each user calculation and just keep my previous place in the loop and this sounds like a good idea, but I wanted to hear some opinions from others that have handled similar situations and how you handled these types of tasks. Thanks.

  • bug fixing appproach

    - by Shirish11
    I have been working on a project comprising of databases. I recently received a bug report for the remote execution of some queries. Usually you try to find out the actual cause for the bug to occur and then fix it. But sometimes what I do when I'm fed up of doing some research (and can't find suitable information on the internet) is just change the logic, which takes me much less time compared to the other option. Is this approach of mine correct or should I try to fix the original bug involving more R&D?

  • Postfix connects to wrong relay?

    - by Eric
    I am trying to set up postfix on my ubuntu server in order to send emails via my isp's smtp server. I seem to have missed something because the mail.log tells me: Jan 19 11:23:11 mediaserver postfix/smtp[5722]: CD73EA05B7: to=<[email protected]>, relay=new.mailia.net[85.183.240.20]:25, delay=6.2, delays=5.7/0.02/0.5/0, dsn=4.7.0, status=deferred (SASL authentication failed; server new.mailia.net[85.183.240.20] said: 535 5.7.0 Error: authentication failed: ) The relay "new.mailia.net[85.183.240.20]:25" was not set up by me.

  • Xubuntu stuck after login

    - by viraptor
    How can I debug an issue with Xubuntu 12.04 (fresh install) which just waits idle after a login for about 30 seconds? The login screen is delayed correctly. After login, I get my desktop background, but no panels or auto-starting apps. It doesn't seem to be an authentication/pam issue, because I can login without delay at the console while the graphical session is still stuck. There's no disk or cpu activity and no obvious respawning of any process when I look at htop. There's nothing obviously wrong in .xsession-errors. Most interesting errors: openConnection: connect: No such file or directory cannot connect to brltty at :0 WARNING: gnome-keyring:: couldn't connect to: /tmp/keyring-wFn4VR/pkcs11: No such file or directory ...

  • Errors with linux-image-3.8.0-36-generic and GRUB

See screenshot below. Grub files + terminal window (screenshot) Pastebin with terminal output while trying to install something I should mention that I don't known if these two errors are related, but it is a fact that every time I try to install something or run an update both of the above errors pop up.

  • Is there other ways to do insert/update/delete on a remote oracle database?

    - by gunbuster363
    I asked a question recently concerning the speed of execution of insert/update/delete using JDBC driver in a remote machine, but the problem cannot be solved easily. I would like to ask, is there any other way to execute the insert/update/delete to the oracle? The current situation is this: the DB is on a seperate machine than the java program used to update the DB. I looked up the internet and found people suggesting using pure sql or pl/sql to do the update, is that possible? And do we need to operate the sql or pl/sql in a local machine? Because I have no knowledge about pl/sql, so I am not sure if we can create some kind of script and call it on a remote machine. Let say the situation is like this: the input data is on machine A, and the original java program are also on machine A, but the oracle is on machine B. is there any other approach other than JDBC?

  • BicaVM : une implémentation de la machine virtuelle Java en JavaScript

    BicaVM : l'implémentation de la machine virtuelle Java en JavaScript Les navigateurs pourront dans un futur proche intégrer une sorte de machine virtuelle, permettant d'exécuter du code d'un langage autre que du JavaScript. C'est la vision d'un développeur qui vient de mettre sur pied une machine virtuelle Java en JavaScript. Arthur Ventura, un développeur portugais des solutions open sources, vient de présenter BicaVM, une implémentation de la machine virtuelle Java (JVM) en JavaScript, capable de fonctionner dans n'importe quel navigateur moderne. La principale difficulté du port de la JVM en JavaScript est le temps d'exécution du bytecode. Cependant, avec les importantes augmentations de la vitesse d'ex...

Ce langage reste le plus performant et sans conteste ! Présenté au Scala Days en début de mois, un benchmark met en compétition le C++, Java, Scala et GO pour l'implémentation du même algorithme en cherchant à s'appuyer sur les éléments du langage (pas de Boost ici donc). Et C++ remporte haut la main en temps d'exécution mais aussi en empreinte mémoire. Mieux, contrairement à certaines idées reçues, les temps de compilation ou le nombre de ligne de code restent à des valeurs qui n'ont pas à rougir face à Java par exemple....

  • How to write loosely coupled classes in node.js

    - by lortabac
    I am trying to understand how to design node.js applications, but it seems there is something I can't grasp about asynchronous programming. Let's say my application needs to access a database. In a synchronous environment I would implement a data access class with a read() method, returning an associative array. In node.js, because code is executed asynchronously, this method can't return a value, so, after execution, it will have to "do" something as a side effect. It will then contain at least 1 line of extraneous code which has nothing to do with data access. Multiply this for all methods and all classes and you will very soon have an unmanageable "code soup". What is the proper way to handle this problem? Am I approaching it the wrong way?

  • When profiling a function for time use, what information is desirable?

    - by AaronMcSmooth
    I'm writing a program similar to Python's timeit module. The idea is to time a function by executing it anywhere from 10 to 100,000 times depending on how long it takes and then report results. I've read that the most important number is the minimum execution time because this is the number that best reflects how fast the machine can run the code in question in the absence of other programs competing for processor time and memory. This argument makes sense to me. Would you be happy with this? Would you want to know the average time or the standard deviation? Is there some other measure that you consider more important?

  • JavaScript malware analysis

    - by begueradj
    I want to test websites for JavaScript malware presence . I plan to develop a Python program that sends the URL of a given website to a virtual machine where the dynamic execution of the eventual malicious JavaScript embedded in the website's page is monitored. My questions: Should my VM be Windows or Linux ? What if the malware damages my VM: is there a hint how to avoid that ? Or launch a new VM automatically instead ? If I use telnet client library to communicate with the VM: must I implement a server within the VM to deal with my queries or can I overcome this ? I am jut looing for hints, general ideas. Thank you for any help.

  • Where do the responsibilities of build tools end and those of CI tools start?

    - by BrandonV
    In the delivery of software, and within the sense of the deployment pipeline, where do the responsibilities of build tools, like Maven, end, and the responsibilities of CI start? As a rough example of a problem that arises; should build tools have any responsibility to the configuration and execution of acceptance tests when they are further down the pipeline than actually building the artifact? I'd like an answer that addresses in the sense of deployment lifecycle phases rather than in specifics, like my example. Although examples would help bolster the answer.

  • Communication between Box2D and libGDX Stage (Scene2D) running in separate threads

    - by atok
    I'm making a physics based 2D game using libGDX and Box2D. I want to move the execution of the simulation out of render thread. I use immutable messages and the BlockingQueue to pass the information about player actions. The Box2D applies forces and runs a frame of simulation. In the next step I would like to sync back the changes and update Scene2D Actors accordingly. Making an immutable copy of the state of the game world and sending it back using Gdx.app.postRunnable() is one option but it seems inefficient. Is there any other option?

    We have an apache webserver in front of Tomcat hosted on EC2, instance type is extra large with 34GB memory. Our application deals with lot of external webservices and we have a very lousy external webservice which takes almost 300 seconds to respond to requests during peak hours. During peak hours the server chokes at just about 300 httpd processes. ps -ef | grep httpd | wc -l =300 I have googled and found numerous suggestions but nothing seems to work.. following are some configuration i have done which are directly taken from online resources. I have increased the limits of max connection and max clients in both apache and tomcat. here are the configuration details: //apache <IfModule prefork.c> StartServers 100 MinSpareServers 10 MaxSpareServers 10 ServerLimit 50000 MaxClients 50000 MaxRequestsPerChild 2000 </IfModule> //tomcat <Connector port="8080" protocol="org.apache.coyote.http11.Http11NioProtocol" connectionTimeout="600000" redirectPort="8443" enableLookups="false" maxThreads="1500" compressableMimeType="text/html,text/xml,text/plain,text/css,application/x-javascript,text/vnd.wap.wml,text/vnd.wap.wmlscript,application/xhtml+xml,application/xml-dtd,application/xslt+xml" compression="on"/> //Sysctl.conf net.ipv4.tcp_tw_reuse=1 net.ipv4.tcp_tw_recycle=1 fs.file-max = 5049800 vm.min_free_kbytes = 204800 vm.page-cluster = 20 vm.swappiness = 90 net.ipv4.tcp_rfc1337=1 net.ipv4.tcp_max_orphans = 65536 net.ipv4.ip_local_port_range = 5000 65000 net.core.somaxconn = 1024 I have been trying numerous suggestions but in vain.. how to fix this?
