• Sending a large number of mails causing problems on CentOS 6 / Plesk 10

  - by papakost

  I have a VPS running CentOS 6. When the system tries to send daily newsletter, after some time (e.g. after sending about 2000 emails), I get error "Unable to send mail" and the system memory goes really high. Till this moment, the mails are delivered normally. The rest symptoms are: I cannot see anything on /var/log/maillog (File seems not to be written) All files on /var/spool/mail have 0 bytes size. From time to time on httpd log I get errors like: /usr/sbin/sendmail: error while loading shared libraries: libc.so.6: cannot open shared object file: Error 23 "Activate mail service on domain" setting in Plesk is deactivated. Any idea on what's going wrong here?

• How to get the spec of a machine on Linux?

  - by machinePurchaser

  I am interested in getting the spec of a machine, because I am thinking getting a similar server. What I am mostly interested in knowing is the number of cores / CPUs / etc., the amount of memory, the speed of the CPUs, the CPU cache size, and any other detail which is important for performance. My question is two-fold: Which parameters should I be interested in other than the ones I specified above? Is there an easy way to read them off the machine in Linux? cat /proc/cpuinfo reveals a lot about the CPUs, for example... What about memory (would rather not rely on top), etc?

• Recover files after unsuccessful partitioning

  - by arsan

  I wanted to install another Linux on my computer, so I tried to resize one of my NTFS partitions with Norton Partition Magic. It didn't complete successfully, showed some errors, said that the partition is not resized and that it's the same size like before. But when I rebooted my computer I couldn't open that partition anymore and I am also not able to mount it from Linux. So this is my question: I had very important data on that partition - can I recover it? I guess nothing's deleted; it's just something messed up so it's not usable, but can I get it back? Please reply if there's any possible way of doing this, thank you.

• Rendering multiple squares fast?

  - by Sam

  so I'm doing my first steps with openGL development on android and I'm kinda stuck at some serious performance issues... What I'm trying to do is render a whole grid of single colored squares on to the screen and I'm getting framerates of ~7FPS. The squares are 9px in size right now with one pixel border in between, so I get a few thousand of them. I have a class "Square" and the Renderer iterates over all Squares every frame and calls the draw() method of each (just the iteration is fast enough, with no openGL code the whole thing runs smootlhy at 60FPS). Right now the draw() method looks like this: // Prepare the square coordinate data GLES20.glVertexAttribPointer(mPositionHandle, COORDS_PER_VERTEX, GLES20.GL_FLOAT, false, vertexStride, vertexBuffer); // Set color for drawing the square GLES20.glUniform4fv(mColorHandle, 1, color, 0); // Draw the square GLES20.glDrawElements(GLES20.GL_TRIANGLES, drawOrder.length, GLES20.GL_UNSIGNED_SHORT, drawListBuffer); So its actually only 3 openGL calls. Everything else (loading shaders, filling buffers, getting appropriate handles, etc.) is done in the Constructor and things like the Program and the handles are also static attributes. What am I missing here, why is it rendering so slow? I've also tried loading the buffer data into VBOs, but this is actually slower... Maybe I did something wrong though. Any help greatly appreciated! :)

• Series On Embedded Development (Part 3) - Runtime Optionality

  - by Darryl Mocek

  What is runtime optionality? Runtime optionality means writing and packaging your code in such a way that all of the features are available at runtime, but aren't loaded and used if the feature isn't used. The code is separate, and you can even remove the code to save persistent storage if you know the feature will not be used. In native programming terms, it's splitting your application into separate shared libraries so you only have to load what you're using, which means it only impacts volatile memory when enabled at runtime. All the functionality is there, but if it's not used at runtime, it's not loaded. A good example of this in Java is JVMTI, Java's Virtual Machine Tool Interface. On smaller, embedded platforms, these libraries may not be there. If the libraries are not there, there's no effect on the runtime as long as you don't try to use the JVMTI features. There is a trade-off between size/performance and flexibility here. Putting code in separate libraries means loading that code will take longer and it will typically take up more persistent space. However, if the code is rarely used, you can save volatile memory by including it in a separate library. You can also use this method in Java by putting rarely-used code into one or more separate JAR's. Loading a JAR and parsing it takes CPU cycles and volatile memory. Putting all of your application's code into a single JAR means more processing for that JAR. Consider putting rarely-used code in a separate library/JAR.

• df says disk is full, but it is not

  - by Chris

  On a virtualized server running Ubuntu 10.04, df reports the following: # df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 7.4G 7.0G 0 100% / none 498M 160K 498M 1% /dev none 500M 0 500M 0% /dev/shm none 500M 92K 500M 1% /var/run none 500M 0 500M 0% /var/lock none 500M 0 500M 0% /lib/init/rw /dev/sda3 917G 305G 566G 36% /home This is puzzling me for two reasons: 1.) df says that /dev/sda1, mounted at /, has a 7.4 gigabyte capacity, of which only 7.0 gigabytes are in use, yet it reports / being 100 percent full; and 2.) I can create files on / so it clearly does have space left. Possibly relevant is that the directory /www is a symbolic link to /home/www, which is on a different partition (/dev/sda3, mounted at /home). Can anyone offer suggestions on what might be going on here? The server appears to be working without issue, but I want to make sure there's not a problem with the partition table, file systems or something else which might result in implosion (or explosion) later.

• Windows Server 2008 Static IP Address

  - by Gauls

  I have Win 2008 Server VM and want to set static IP address so that i can RDP into instead of using VM player (mouse gets out of focus as the size of the VM increases). Now while making the changes i see two TC/IPv6 and TC/IPv4 i try changing the IPaddress from obtain autimatically, but it always goes to "Unidentified Network". If i leave it to automatically obtain IP,i still cannot RDP into it. I have tired disabling TC/IPv6 from reistry. Any other suggestions? BTW the same setting works fine with WIN XP and i can RDP into all Win XP VM's Cheers Gauls

• To Run Linux (Ubuntu) on Windows 7, is using Virtual PC one of the best ways?

  - by Jian Lin

  I need to try Linux (Ubuntu) and feel hesitant to install Ubuntu on top of a Win 7 machine to dual boot (might need to use Win7 and Ubuntu at the same time). Is creating a Virtual PC on Win7, and then installing the latest Ubuntu on that Virtual PC one of the better option? So I think I can create a Virtual PC with an empty virtual hard disk (vhd), say, for 30GB, and then put in the Ubuntu DVD-R or CD-R to install Ubuntu onto that empty hard disk. Update: for some reason, the first time Ubuntu 10.04 installation CD-R boots up, it asked for the Language, and "Install Ubuntu" and then the screen has vertical green bars and then the VPC just closed. The 2nd or 3rd time it booted up, there is no asking of Language or "Install Ubuntu" and just shut down the VPC, sometimes with vertical green bars. I even created another new hard drive and same thing happened. And created VPC 02, and same thing happened. Created VPC 03 with a fixed hard drive size of 60GB and same thing happened.

• How to suggest changes as a recently-hired employee ?

  - by ereOn

  Hi, I was recently hired in a big company (thousands of people, to give an idea of the size). They said they hired me because of my rigor and because I was, despite my youngness (i'm 25), experienced as a C/C++ programer. Now that I'm in, I can see that the whole system is old and often uses obsolete technologies. There is no naming convention (files, functions, variables, ...), they don't use Version Control, don't use exceptions or polymorphism and it seems like almost everybody lost his passion (some of them are only 30 years old). I'd like to suggest somes changes but i don't want to be "the new guy that wants to change everything just because he doesn't want to fit in". I tried to "fit in", but actually, It takes me one week to do what I would do in one afternoon, just because of the poor tools we're forced to use. A lot my collegues never look at the new "things" and techniques that people use nowadays. It's like they just given up. The situation is really frustrating. Have you ever been in a similar situation and, if so, what advices would you give me ? Is there a subtle way of changing things without becoming the black sheep here ? Or should I just give up my passion and energy as well ? Thank you. Updates Just in case (if anyone cares): following your precious advices I was able to suggest changes and am now in charge of the team that must create and deploy Subversion :D Thanks to all of you !

• Which file system to choose from when formatting 1.5TB hard drive (hdd)

  - by MaxiWheat

  I plan to buy a 1.5TB hard drive soon. I would like to know which file system to choose from when I'm gonna format it. With FAT32, there is a limitation concerning the maximum file size (4GB) that bugs me since I might save large files such as DVD images which are over 4GB. On the other hand, NTFS allows me to save larger files, but seems less compatible with other OS than Windows and is also proprietary to Microsoft. Are there other alternatives ? Can you give me your advices ?

• How do you QA and release software quickly (some call it agile) with a large team?

  - by sadadasd

  My work used to be a smaller team. We had less than 13 devs for a while. We are now growing rapidly, and are over 20 with plans to be over 30 in a few months (triple dev size!!!) Our process for QA'ing and releasing each build is no longer working. We currently have everyone develop the new code, and stick it onto a staging environment. A few days before our weekly release, we would freeze the staging environement and QA everything new / old. By our normal release time everything was usually deemed acceptable and pushed out the door to the main site. We reached a point where our code got too big so we could no longer regress the entire site each week in QA. We were ok with that, we jsut made a list of everything important and only covered that and the new stuff. Now we are reaching a point where all the new stuff each week is becoming too big and too unstable. Our staging environment is really buggy week after week, and we are usually 1-2 hrs behind the normal release time. As the team is growing further, we are going to drown with this same process. We are re-evaluating everything, and I personally am looking for suggestions / success stories. Many companies have been where before and progressed beyond, we need to do the same

• How can one tell that FLAC or WAVPACK audio file is NOT originally encoded from a Lossy source?

  - by cornel

  Hi everyone, Forgive me for my ignorance,firstly. Problem: Say I have a lossy mp3 audio file(5.17Mb ie. 87% compressed from its original souce-unknown), I then encode it to another LOSSLESS format, say FLAC or WAVPACK. The size increases(23.14Mb ie. 39% compressed from its original souce-mp3)! ID tags, etc remain the same and there's no way of checking the integrity of its origin. Question: Is there a way of checking that the so-called FLAC or WAVPACK audio file was originally encoded from a LOSSLESS source(wav,cda,ape,...etc) instead of a LOSSY source(mp3,aac,ATRAC,..etc) Thank you. Best regards, L-I-C(Lost In Compression)

• HP DV5T laptop problems using Adobe in multiple monitors

  - by Rolnik

  I have a dualview arrangement of two monitors that works just fine for 90% of my applications. However, any time I open Adobe Acrobat Reader to the larger monitor, it fails to permit enlarging of the window to fill the entire screen. In other words, it seems Adobe crops the PDF view at about the size of the smaller of the two monitors, despite Acrobat being present in the larger monitor. I'm using nVideo graphics on the laptop, and connecting to the larger monitor through the docking port of a docking station. Any ideas how to get the Acrobat to be aware that it has more screen real-estate and use it fully?

  Hello, I am trying to write a reward system wherein users will be given reward points if they download complete files, So what should be my log format. After searching alot this is what I understand its my first time and havent done custom logs before. First of all which file should I edit for custom logs because this thing I cant find. I am using ubuntu server with default apache, php5 and mysql installation # I use this commands and they work fine nano /etc/apache2/apache2.conf /etc/init.d/apache2 restart I think this is what I need to do for my purpose LogLevel notice LogFormat "%f %u %x %o" rewards CustomLog /var/www/logs/rewards_log rewards This is as it is command or there is something missing? and is there any particular location where I need to add this? and one more thing %o is for filesize that was sent and is it possible to log only files from a particular directory? or for files with size more than 10mb. Thank You.

• DD-WRT: What firmware and what webserver will fit on my 8MB of flash?

  - by Jeshii

  Attempting to make a portable WiFi webserver with php support on an old WRT54GS (v1.0) with DD-WRT. I have 8MB of flash on there. I know, it's a tall order. I tried the combination of dd-wrt.v24-13064_VINT_openvpn_jffs_small.bin, optware, and lighttpd. Didn't have enough space. Now I'm going to try dd-wrt.v24-13064_VINT_mini.bin, but I'm only saving 300KB, and I don't think that is going to make the difference. Any other small http servers with php support? Heck, I didn't even got to the point where I could add php! Maybe a way to calculate the size and dependencies of packages from optware BEFORE trying to install is more what I'm looking for. Any ideas?

• Moving windows using keyboard...faster?

  - by Alois Mahdal

  I like using keyboard shortcuts because it's faster as it does not force me to move my hands off the keyboard. In Windows I can use them to move windows around desktop: Press Alt+Space to open common windows menu Press M to choose "Move" command Navigate window position by cursor keys Confirm new position with Enter Additionally, to achieve better accuracy, I can hold Ctrl while navigating. Now the problem is that the normal "step" when moving is about 20px, and my desktop is quite large, so "walking" all the way across takes quite a long time. This kind of defeats the purpose of using keyboard for these tasks. Is it possible to change size of this step so that takes less steps to walk the same distance? (I imagine a hidden setting in Windows registry...?) I tried holding Alt while navigating, but it does not seem to have influence on speed.

• How do I understand the partition table? (I want to start over.)

  - by Sammy Black

  I have Ubuntu 10.04 Lucid installed through wubi on my laptop (it came with Windows 7 preinstalled). This was my first foray into Linux, and I'm here to stay. I have no use for Windows, and yet I must manually choose not to boot into it! Should I shrink the Windows partition to something negligible and grow the Linux one using something like gparted or fdisk, and just be content that everything runs? In that case, I need to understand the filesystems. Which is which? Here's the output of $ df -h: Filesystem Size Used Avail Use% Mounted on /dev/loop0 17G 11G 4.5G 71% / none 1.8G 300K 1.8G 1% /dev none 1.8G 376K 1.8G 1% /dev/shm none 1.8G 316K 1.8G 1% /var/run none 1.8G 0 1.8G 0% /var/lock none 1.8G 0 1.8G 0% /lib/init/rw /dev/sda3 290G 50G 240G 18% /host I would prefer to start over with a clean install of 10.10 Maverick, but I fear what I may lose. Certainly, I will backup my home directory tree (gzip?), but what about various pieces of software that I've acquired from the repositories? Can I keep a record of them? By the way, I asked a similar question over on Ubuntu forums.

• Installing Ubuntu next to Windows XP

  - by jess

  I have iso image for Ubuntu 11.0.4 on a CD. My OS is windows XP. I have 3 partions c, E and F. Windows is installed on C, and F has data. E is empty drive. Now, after I start installation , I choose the third option. Then click forward and I am shown three figures -- /dev/sda1 52427(total)/50931(used) /dev/sda5 52427(total)/3221(used) -- surprised, since it should be empty. I had used wubi to install earlier but have uninstalled. /dev/sda5 215206(total)/37545(used) Now, it means I need to choose sda5. Now how should I go about creating 3 partions for /(root), /home and /swap. Click edit partion and give size for each of them?

• ubuntu live cd start up error

  - by Emiel

  First off, I'm new to the Linux scene. This is my first attempt to make a single boot installation for Ubuntu. I tried it for a few days in dual boot with win7 and I was sold, so i removed the tumor my pc had to endure for so long (sorry laptop) and installed Ubuntu from an usb boot device. My dual boot was as follows: Windows 7 was installed on partition C from hdd1, the windows installer for Ubuntu installed Ubuntu on partition I on that same hdd, hdd1. In the live cd installation I did the normal execution for removing windows and it said that after the installation my partition would be 320gb big, that is the total size of my hdd, so I automatically assumed that it would format my whole hdd. Now the installation has completed and it tells me to restart my system, and here comes the problem: now I get a dashing white cursor on my screen after the BIOS load and it won't budge... it just stands there and it doesn't move on or load Ubuntu, the system gets very hot at this point... Then I tried to reinstall using the same live CD, it is still on my USB drive, but when I boot from the USB, I get the error: no such file with some address and the a grub rescue. What to do? I can get hold of a win7 copy, but I don't really want to use that crap again... Thanks for helping me out. Kind regards, Emiel

• What are some best practices for minimizing code?

  - by CrystalBlue

  While maintaining the sites our development team has created, we have come across include files and plugins that have proven to be very useful to more then one part of our applications. Most of these modules have come with two different files, a normal source file and a min file. Seeing that the performance and speed of a page can be increased by minimizing the size of the file, we're looking into doing that to our pages as well. The problem that we run into is a lot of our normal pages (written in ASP classic) is a mix of HTML, ASP, Javascript, CSS, and include files. We have some pages that have their JS both in include files and in the page, depending on if the function is only really used in that page or if it's used in many other pages. For example, we have a common.js and an ajax.js file, both are used in a lot of pages, but not all of them. As well as having some functions in a page that doesn't really make sense to put into one master page. What I have seen a few other people do online is use one master JS file and place all of their javascript into that, minify it, gzip it, and only use that on their production server. Again, this would be great, but I don't know if that fully works for our purposes. What I'm looking for is some direction to go with on this. I'm in favor of taking all of our JS and putting it in one include file, and just having it included in every page that is hit. However, not every page we have needs every bit of JS. So would it be worth the compilation and minifying of the files into one master file and include it everywhere, or would it be better to minify all other files and still include them on a need-to-use basis?

• How do I recover a RAID 1 volume on Mac OS X (10.7)?

  - by Avry

  I have a Synology NAS that I've set up with RAID 1. The device is set up with two drives, both the same size (i.e. 500 GB each), formatted in ext3, as a RAID 1 volume (i.e. even though the total capacity is 1TB, I effectively only get 500 GB). In the case of a device failure where I can only access one of the drives, how can I recover my data? The solution I'm looking for is something like: 'Put the working drive in an enclosure, and use <some software> to recover your data.'

In this session Kraig Brockschmidt cover a wide array of dos and don’ts for implementing live tiles.  I was actually worried whether I would get much out of this session when Kraig started it off with the fact that his background is in HTML5 based apps which I have little interest in, but the subject almost didn’t come up during his talk.  It focused on things like making sure you have all the right size graphics and implementing all of the tile event handlers.  The session went on to discuss the message format for push notification and implementing lock screen notification and badges. As with the other day 1 sessions it was like drinking from a fire hose, but it was good stuff.  Check it out when they post it on Channel 9. del.icio.us Tags: BUILD 2013,Live Tiles,Windows 8.1

• Justification of Amazon EC2 Performance

  - by Adroidist

  I have a .jar file that represents a server which receives over TCP an image in bytes (of size at most 500 kb) and writes it file. It then sobels this image and sends it over TCP socket to the client side. I ran it on my laptop and it was very fast. But when I put it on Amazon EC2 server m1.large instance, i found out it is very slow - around 10 times slower. It might be the inefficiency in the code algorithm but in fact my code is nothing but receive image (like any byte file) run the sobel algorithm and send. I have the following questions: 1- Is it normal performance of Amazon EC2 server- I have read the following links link1 and link2 2- Even if the code is not that efficient, the server is finally handling a very low load (just one client), does the "inefficient" code justify such performance? 3- My laptop is dual core only...Why would the amazon ec2 server have worse performance that my laptop? How is this explained? Excuse me for my ignorance.
