• HTML5 applicationCache in local development

  - by jesper

  I'm experimenting with application cache based on this example: http://html5demos.com/html5demo.manifest This example works fine in ff, but when I create analogous site (almost identical) I get only status "UNCACHED (numeric value 0) -- The ApplicationCache object's cache host is not associated with an application cache at this time." I work on xampp and I've set correct mime-type. When the page is loading ff "is asking to store data on your computer for offline use" and when I show Tools - Options - Advanced - Network - Offline data there is localhost but with 0B size.

• How can I get the current network interface throughput statistics on Linux/UNIX?

  - by DavidM

  Tools such as MRTG provide network throughput / bandwidth graphs for the current network utilisation on specific interfaces, such as eth0. How can I return that information at the command line on Linux/UNIX? Preferably this would be without installing anything other than what is available on the system as standard.

• Online graphing and data visualization frameworks

  - by Marques

  I have been looking around at web applications and websites with rich graphs, charts, and data visualization and for the most part have been able to determine which frameworks or tools websites are using. However I was looking over 'resumup.com' and couldn't determine what they are using. Does anyone know off hand or can you tell? It doesn't seem like any javascript framework i've seen unless its custom...is it some sort of flash or flex framework? Any help would be greatly appreciated. Thanks, Marques

• How to find where a library is used across multiple pom files

  - by Pablojim

  We have multiple maven projects depending on on our own common libraries. When we upgrade a library it would be useful to quickly find out which projects have a dependency on the library (and might need to use the new version) Obviously I can manually look in all the pom files or write a script to do it but this is less than ideal. Are there any tools that provide this functionality. e.g. a hudson plugin, Nexus, artifactory etc?

• Migrating WebLogic 10.3.0 to new host. Slow managed server startup times

  - by wadevondoom

  We are migrating our Blue Martini Commerce application (only supported on WebLogic 10.3.0) to a new host (Redhat 6.3 on a VMWare ESX vm). We are seeing extremely slow start up times for our managed server(s) that is basically 20x slower than our current production. As a for instance the Publish managed server takes ~30 - 45 seconds in current production and in the new environment it takes ~10 minutes. The setup uses the same domain structure and JVM as the current production environment. The same setup files are used. We use jdk1.6.0_33 on 64 bit architecture. We used the generic 64bit weblogic installer and used pack / unpack utilities to migrate the domain. The JAVA_OPTS to start this server are: "-d64 -Xms256m -Xmx512m -XX:PermSize=48m -XX:MaxPermSize=256m" The sysadmins have checked /etc/sysctl.conf and /etc/limits.conf to ensure we were not hitting some kind of process limit. As I am not sure what this managed server does from a Blue Martini perspective during the phase of startup I also had the DBA check to ensure that Oracle RAC (11.2.0.3) wasn't also hitting some kind of process limit or if there was a tns listener issue. The new host is quite a bit stricter with their server lock downs so there are a few differences.... Redhat 6.3 in new env, RH 5.7 in current SElinux is targeted in new env and disabled in current VM in new env and dedicated hardware in current iptables disabled in current. It was enabled in new prod but I had them disable it just in case I apologize for not being more specific. I am mostly hoping got some tips. I do not have the typical root access I would normally have in this environment. I am just hoping got a path forward. I did a few 'kill -3' to see if there are blocked threads and I got nadda. The service works for all intents and purposes it is just painfully slow. Thanks you all in advance for reading and best regards. Wade

• avoid textarea rows/cols error?

  - by acidzombie24

  I am using a few page validation tools one problem i have is they tell me textarea must have rows and cols attribute. If i am setting this in CSS or using display:none (and using it to hold raw text data) can i do something to skip? it seems like the only answer is rows="0" cols="0" each time i use it. But i have a feeling that is not a good solution.

• How to go about rotating logs which are arbitrary named and placed in deeply nested directories?

  - by Roman Grazhdan

  I have a couple of hosts which are basically a playground for developers. On these hosts, each of them has a directory under /tmp where he is free to do all he wants - store files, write logs etc. Of course, the logs are to be rotated, or else the disc will be 100% full in a week. The files can be plenty, but I've dealt with it with paths like /tmp/[a-e]*/* and so on and lived happily for a while, but as they try new cool stuff on the machine logrotate rules grow ugly and unmanageable, and it's getting more difficult to understand which files hit the glob. Also, logrotate would segfault if asked to rotate a socket. I don't feel like trying to enforce some naming policies in that environment, I think it's going to take quite a lot of time and get people annoyed and still would fail at some point. And I still need to manage the logs, not just rm the dirs at night. So is it a good idea in circumstances like these to write a script which would handle these temporary files? I prefer sticking with standard utilities whenever possible, but here I think logrotate is getting less and less manageable. And probably someone heard of some logrotate alternatives which would work well in such an environment? I don't need emailing logs or some other advanced features, so theoretically some well commented find | xargs would do. P.S. I do have a log aggregator but this stuff is not going to touch my little cute logstash machine.

• how to deal with political differences that lead to dysfunctional development environment

  - by Pierreten

  We have a few liberal programmers on our team who don't use source control, don't manage time effectively and always want to use our budget on useless tools/components that are expensive and things we can build ourselves. They are also loud and disrespectful. Our group of conservatives always have to clean up after them and show them the correct way of doing things. How do we address this discrepancy? Please advise.

• Production debugging: Is there a less intrusive way than WinDbg?

  - by Alex

  Hi, I was wondering if there is a less intrusive way to analyze a running, managed process in production environments. Less intrusive meaning: No delay of execution when attaching the debugger. No delay of execution when getting basic stats like running threads. In the Java world there is a such a tool part of the JDK. I was wondering if there're similar tools in the .NET world. Any ideas?

• Enabling ProGuard in Eclipse for Android

  - by Ted Hopp

  The new documentation on ProGuard for Android says to add a line to the default.properties file in the project home directory. However, on opening this file, I read at the top: # This file is automatically generated by Android Tools. # Do not modify this file -- YOUR CHANGES WILL BE ERASED! Am I missing something? Also, is there a way to enable ProGuard only for a production build from Eclipse (i.e., when exporting the finished product)?

• Please recommend a Java profiler

  - by Yuval F

  I am looking for the Java equivalent of gprof. I did a little Java profiling using System.getCurrentMillis(), and saw several GUI tools which seem too much. A good compromise could be a text-based Java profiler, preferably free or low-cost, which works in either Windows XP or Linux.

• How do you set the default source for the Output window in Visual Studio?

  - by Grank

  We added a SharePoint BDC model project to a solution in Visual Studio 2010. Ever since, whenever the solution is built, instead of showing the Build output in the Output window, it insists on having "SharePoint Tools" selected in the "Show Output from:" drop-down, just to say "Model validation started ... Model validation completed with no errors." Short of shutting off any SharePoint projects in the build configuration, can this behavior be overridden?

• Random keyboard malfunction - happens in Vista and XP

  - by Stupefy101

  For some weird reason, some of my keyboard keys of my deskop are acting very strangely. I don't remember a certain time when it started and I can't recognize any pattern as to when it happens and when it doesn't. The problem occurs in Windows XP, XP Safe Mode, Vista, and Vista Safe mode (I have a dual boot system) Here's what's happening: When I push the I, K, comma, or 8 keys (notice how they are all in the same column), instead of just getting that character, I get extra characters afterwards. For example, I'll push the k key and it will print "ksfda", pushing "I" gives me "IWREQ", comma gives me ", xvcz", pushing 8 gives me "82431". There are a couple things that I have noticed: It does not happen every time I push the key It happens in all OS and applications I have tested The characters coming after the desired ones are in the same pattern (column order: 2, 4, 3, 1 from the left of the keyboard in the same row as the key pressed. Pressing "]" will sometimes give me "]t", and if done in Notepad, will bring up the "Find" dialog window I cannot seem to remember a specific time the problem started, although I have been defragging, using TuneUp Utilities + CCleaner, and installing lots of new programs lately.

• What is the best .NET Obfuscator tool on the market?

  - by markattwood

  I have tried .NET Reactor but it seems to break our complex application even with the most simple option (just rename method name). Also, it does not provide any option to filter method names by Regex like DotFuscator. DotFuscator is very good but it is too expensive. I have heard about Xeno code and other tools. Any one has any ideas on which one is best?

• Is there any way to customize the Windows 7 taskbar auto-hide behavior? Delay activation? Timer?

  - by calbar

  I'm becoming increasingly frustrated with the way Windows 7 handles showing a hidden taskbar. It's incredibly over-eager to pop out and obscure what I'm really trying to interact with, requiring me to move the mouse away, wait for it to auto-hide again, then resume what I was doing but more deliberately. After closely examining the behavior, it appears that a hidden taskbar "peeks out" from the edge by 2 or 3 pixels, and slowly moving your mouse into this area activates it; you don't even need to touch the edge of the screen. I would love it if there was a way to customize or change this behavior. Ideally, the taskbar would only pop out if you are actively "pushing" the edge of the screen it is hidden on. So activation only occurs once you've reached the screens edge and continue to move the mouse past a customizable threshold. Alternatively, a simple activation delay would suffice as well. So only if the mouse remains in that 2-3 pixel area (a.k.a. on the taskbar) for greater than a customizable amount of time does it pop out again. This would only be a fraction of a second. Often times the cursor simply "careens" off the edge of the screen while trying to focus on something nearby. Anyway, if there are any registry settings or utilities that can achieve either of these effects, that would be great! Thanks for your help.
