Subversion is very slow in IDEA 10.5, It always refresh Subversion history after update java source or commit, every refresh Subversion history about cost 30 seconds，but in Eclipse,Subversion is very fast
What OS are you running? I've seen some problems with 64 bit only Linux kernels and jsvn earlier.
There can be multiple reason,
Subversion repository connectivity can be very slow or may have huge network traffic.
It can be also caused by insufficient performance of your computer.
As far as I know there know intelij Idea 10.5 related issues with subversion. Any way try 11.0.1 it is more stable and more features compared to 10.5

First my specs are an Intel i7 toshiba laptop with 8gigs of RAM running windows 8.1 with all the latest updates. When I first launch any of Jetbrains IDEs after install, it would ask me for my workspace location and then it would proceed to do nothing after than, but it stays in memory and slows down my entire system for about a minute, after that, the computer stops being slow and returns to normal but the program still does nothing (no GUI) but still remains in memory, what is going on??? Thanks in advance.
It's hard giving a definite answer to your question. But it sounds to me like you have a problem with your Java. Make sure you have it installed and at the latest version.
Also, try looking for matching bugs in the JetBrains bug tracker.
Replacing the jre folder within the IDE folder (pycharm,intelliJ,etc.) with one from an updated JDK install not JRE install.
ex:
JDK/jre7 copy over Jetbrains/IDE/jre
fixes the issue
I am using the OS Ubuntu 12.04 and I have installed Netbeans 7.0.1 on it, my laptop's configuration is pretty good but still Netbeans runs really really slow on it and it hangs completely after using it only for a few mins. On doing some research I found that many people suggested to add the following line in the netbeans.conf file "netbeans_jdkhome="/usr/lib/jvm/java-1.7.0-openjdk-amd64"
which I did but nothing has changed. It still lags a lot.
I can think of a couple of things I would try. Firstly, upgrade to NetBeans 7.4 as recent versions of NetBeans do more work in background threads, improving the general responsiveness of the application.
Secondly, in the etc directory of the NetBeans install (on Windows) there's a netbeans.conf. Try editing the netbeans_default_options property to set -J-Xmx to something large, maybe 256m or 512m. That should give NB a bit more space to play with.
Suppose we have AMD GPU (for example Radeon HD 7970) and minimal linux system without X and etc.
What should be installed and what should be launched and how it should be launched to have proper OpenCL environment? In best case it should be headless environment.
Requirements to environment:
GPU visible by OpenCL programs (clinfo for example)
It is possible to monitor temperature and set fan speed (for example using aticonfig).
P.S. Simple install Xserver, catalyst and run X :0 won't work properly. See X server with fglrx driver won't responce after exactly 49 accesses to X server
UPD When you use AMD GPU on linux, OpenCL applications don't see AMD GPU if Xserver isn't launched.
I had similar problem, asked a question and had succeed solving it by myself.
For R9 290 cards and newer i assume you have:
Built kernel 4.14 or later, with amdgpu driver support. There is option in linux kernel config under Graphics Support.
All nesesary firmware .bin blobs are incorporated. To do so easily you may edit buildroot/package/linux-firmware/* contents for buildroot, and manually add BR2_PACKAGE_LINUX_FIRMWARE_AMDGPU option by yourself, along with BR2_PACKAGE_LINUX_FIRMWARE_RADEON (use it as a template). Actually we should post that update to their git.
When booting you should see appropriate dmesg messages about amdgpu initializing, per each adapter. And screen mode should be switched. If you still see large console text and no videomode switch occured during init then you have problem in kernel/firmware, you should fix that out first.
To answer second question, controlling fan speeds/temperatures is achieved via powerplay filesystem, eg /sys/class/drm/.. like this:
cd sys/class/drm/card0/device/hwmon/hwmon0
echo 1 > pwm1_enable
cat pwm1_max > pwm1
You may dig a bit deeper and find powertune parameters nearby, in device folder.
But instead of using /sys/class/drm/card0/device/pp_dpm_sclk i highly recommend flashing that values directly in cards' bios. Set with required frequencies/voltages, as it is more reliable, stable and api independent - you either init it, or not :)
PS. Also put away 7970, buy something a bit newer. I dont know if it is still supported in the latest drivers, we havent such an old card by hands right now. I tested 290, 390, 480, 580 cards series. (for R9 270, miner fails to build cl code). For older cards better to use some older software <=16.40 and maybe a bit older kernel <=4.13
After referring to many posts, opinions and feedback from SO, I have just bought a Lenovo Thinkpad T410 . x64 Win 7 Prof, 500 GB # 7200 RPM , Core i7 620M processor, 4GB DDR3 RAM.
I am now setting up my development environment on the new machine. I need your suggestions in setting up a clean, structured and risk-free Development Environment.
Something about what I intend to do on this machine:
I am Entrepreneur bootstrapping my Startup. So I will have business related purposes (presentations) other than Coding.
I do coding on Microsoft stack currently for some of my other projects. But will start coding in other technologies such as RoR. So I need to have MS products (VS, IIS) and other OSS'
This machine also doubles up as production environment on top of Development Environment.
I don't have a separate Desktop for doing heavy lifting. This is my whole and sole workstation.
I have read a lot about VMwares here and how they help to keep the machine clean and ordered which you can just wipe out clean and have reinstalled as you wish. Is it a good thing to have VMs each for Microsoft stact, RoR stact and so on or have all of them installed on my main machine itself.
Also, apart from this, it would be great if someone can suggest some good options for Firewall+Antivirus+Malware stack (considering that this is a Win 7 machine)
ThanQ
This machine also doubles up as
production environment on top of
Development Environment.
You are setting yourself up for a world of hurt.
Aside from that, it is just common sense that you should use some form of VCS (I recommend Git) and store all your code NOT on your development machine. You should be able to checkout out your code, run a script, and be up and running. You are bootstrapping a startup; pay the $12/month to keep your code safe.
VMs are a good idea if you need to support different environments, for example Win7, Win Vista, and perhaps some flavor of linux. If you take my suggestion and use a remote VCS setup, you can checkout from the remote source onto your VMs.
Another benefit of VMs is you can set up a base install, with all the software you need, and create an image of it, so from that point on you can pass the image around, and you won't need to install the baseline software again.
As i know java programs are able to run on any Operating System.
and there are JVM's for any kind of machines.
I need a JVM that runs on my PC stand alone, and not on my OS (windows or any thing else).
I mean a JVM that acts like a boot, instead of the OS boot
i searched for all versions of JVM on "www.java.com/en/download/manual.jsp", but i did not get the suitable JVM.
the following link helped me a little but that was not enough
http://java-virtual-machine.net/other.html#jvm
my PC CPU is AMD Athlon(tm) 64X2 Dual Core Processor 5200 + 2.69 GHz
any body can help me to find the suitable jvm version ?!
Sure, have a look at JRockit Virtual Edition. As I understand it it's basically a micro kernel especially tailored for the JRockit VM.
From this page:
Java without the OS: JRockit Virtual Edition (VE)
Am I the only one that's never heard of this before? The Oracle JRockit team is looking at eliminating the OS from the stack required to run Java. This product will be called JRockit VE (not out yet)
JavaOS
Good lucking getting hold of it, though, it's nothing more than a historical curiosity.
There are two JVMs that I am aware of, which have this property:
The Fiji WM: http://www.fiji-systems.com/index.html
According to http://rtjava.blogspot.com/2009/11/new-real-time-vm-was-born-fiji-vm.html it also runs on bare metal.
The next possibility is JNode: an open source operating system where most parts are written in Java (the rest in assembly): http://www.jnode.org/
JNode is still beta, though.
No.
There was an idea of making a machine that could run a JVM as an actual machine (non virtualized), similiar to LISP machines, but that idea never took off...
You need a host OS to run a JVM.
Googling "java real machine" might give you some interesting articles.
I've found two: one from 2004, talking about how such a machine could be built and another one, talking about how JVM runs as a real machine on hardware such as mobile devices.
Still, no dice with a plain PC.
