• Can't run .net software on Samsung Omnia Pro B7330

  - by Sam

  I've got a Samsung Omnia Pro B7330, and am unable to run any program for .net compact framework on it. My last three Smartphones had been HTC brand, and all the programs I tried are just simple winform apps, which ran on all HTC phones. But not on the Omnia. Whenever I try to start an app, I get an "unexpected error" / "NotSupportedException" at: Microsoft.AGL.Common.MISC.HandleArt() System.Windows.Forms.Control._InitInstalce() System.Windows.Forms.Control..ctor() System.Windows.Forms.Button..ctor() MyApp.InitializeComponents() The proper compact framework 2.0 is already installed in the rom, installing CF 3.5 didn't change anything. Anyone can tell me whats the problem with this phone?

• Should I make my project free software?

  - by SkyDan

  The story Over the last couple month I have been working on a pretty big project. It's an enterprise-level software, I designed to be used at a local gym, but I believe it can be used in other places, where things like keeping track of clients, attendances, purchases and payments are required. The problem Well recently, I started to think on how to mature this project from being home-made. Not just because I want my project to grow but also because I would like to have some gain from it. The solutions? And here I saw 2 paths: License the software under some restricted license and try to sell the software to other business around. This way I can get some money for college (I am a high school junior right now) License the software under some free license, publish it on GitHub or something, and try to engage other developers to participate in the project. This way I get experience of working in a team and a better chance that the project will keep growing. The latter would be a good + for my resume, when I'll trying to find a job. So far both ways seem pretty exciting and beneficial to me. The first one offers a good college career, while the second one offers some additional experience and the project's growth. The questions Can anyone point to some other +/- of these 2 options? What would the better option in my situation and why? Or are there other options?

• Eliminating zero-length files

  - by RhZ

  I have been having multiple crashes recently. 4-5 last night within a few hours. I posted about it before, and got an answer but not sure how to proceed. The messages in my logs right before the crash are multiple complaints about valid eCryptfs headers. But the chron might not be related, I don't think I saw that in previous crashes: xxx-desktop kernel: [ 1112.274474] Valid eCryptfs headers not found in file header region or xattr region, inode 32376924 xxx-desktop CRON[4212]: (root) CMD ( cd / && run-parts --report /etc/cron.hourly) So I was sent to an answer providing this script: for i in find $(mount | grep " on $HOME type ecryptfs" | awk '{print $1}') -size 0c; do if ! fuser -v $i; then rm -f $i fi done I did find some zero byte files, not in the exactly right place (a folder called .private as I remember), but I need to fix this, its too bad right now. So I need to delete any of them that are not in use. I am a little too clueless, can someone walk me through executing this script? I don't know how.

• Mobile development, recommended computer configuration?

  - by MikaelW

  Hi, For the last 4 weeks, I have been trying to get into mobile development. Done a couple of tutorials, read some books, developed a couple of dummy Android apps. The thing is my computer is a 5 years old laptop, it is slow and time has come to replace it and I’m looking at different offers online. Have you got any recommendations? Is there any must-have that should make my developer life easier in the future? Is there anything specific that may be useful at a more advanced stage of development that I just can’t think of right now on the hardware side? (I mean apart from good proc, lots of RAM, many USB ports...) One thing I can think of is to have three OS on the same workstation: Windows, Unix and MacOS (so far I focused on android/java/eclipse but am interested in Iphone/objC/xcode as well) but that’s more on the software side. Anyway, would be grateful for any recommendations. Thanks in advance! Mikael PS: I’m quite free on the budget side of things PPS: I'm aware it's not really a programming question but will still be of interest to some programmers here.

• How to make Windows 7 Network show Samba share after VM is rebooted/restored?

  - by lackey

  On Windows 7, I have VirtualBox running Linux (Ubuntu 8.04), with Samba set up so that the Windows host can access it. But if the virtual machine is shut down & restored, or rebooted, the Windows Network no longer shows it. I've tried refreshing many times, restarting Samba, disabling/enabling the virtual network adapter, and running the succession of commands ipconfig /release, ipconfig /flushdns, & ipconfig /renew, but none worked. As a last resort I could restart the host itself, but is there a better way?

• Which server requirment for a Redmine, Git and website hosting?

  - by Ephismen

  Me and 9 other students are going to start a project that will last a minimum of 2 years, for this purpose we are looking to host all our work on a server. Here are a few tools we would like to work with: Redmine GIT Hosting a website/blog to show our work Hosting an internal and private development website/blog We haven't decided yet which OS we will install, but we were looking toward Ubuntu or Fedora. Having a limited budget, 300$/year, we would like to have some advices on the following dedicated server specifications: Kimsufi 2G: Hardware: Intel Celeron/Atom, 1.20 Ghz, 64 bits, 2Gb DDR2, HDD 1 To, Backup FTP 100Gb Network: Connection 100 Mbps, Illimited trafic Dedibox SC: Hardware: Dell Nano U2250, 1x 1,6GHz, 64 bits, 2Gb DDR2, HDD 160 Gb Network: Connection 1Gbit/sec, Illimited trafic Will these server be sufficient? Should we host the websites on another platform? Would a virtualized server be more appropriate? Thank you for your answers, Ephismen.

• Prevent Chrome from automatically opening downloaded PDF and Image files

  - by Phoenix

  When I download a PDF or image in Google Chrome on my Mac, is it possible to prevent Chrome from automatically opening it in my default application for that file type (e.g., Preview)? I notice that Chrome does not do this for other downloaded files such as audio and ZIP archives. I still want to be able to preview files in Chrome; I just want to prevent it from automatically launching my image/PDF viewer application after I download them. For example: I click on a link in an email to a PDF document or an image file. Chrome displays the contents in the browser. I press Cmd-S and save the file to my computer. When the download finishes, the file opens automatically in Preview.app. It's that last step that I would like to bypass.

• Registry (possibly) error in Windows 7 : I can not resize columns in any program except explorer

  - by Klugeman

  I experimented with Winbuilder and after some time I noticed that I cannot resize columns in uTorrent, move bookmarks and bookmark folders in Chrome, then cannot resize columns in Comodo Programs Manager - everywhere !!! Fro example , in uTorrent, columns just froze where I left them last time. But Windows Explorer is functioning properly. Where should I search for this problem ?? I think this is something wrong with registry, but regular registry cleaners do not helps. And I cannot even resize a columns in regedit - this is a real hell !

• Terminal Server Install -- Add/Remove Program Message on NonAdministrator Machines

  - by Brandon

  First time poster... My company uses terminal services for one of our remote offices. Data is kept on a different server. OS is Windows Server 2003. Last week, they needed to purchase a program and have it installed on terminal server, which was done. An administrator session was started, the TS was put into install mode and the program was installed. The TS was then put back into execute mode. The install did not require a reboot. Since then, when any user who does not have administrator privileges initiates a remote session and logs in they get a security message that says "Add / Remove programs has been restricted. Please contact your system administrator." The only option is to click OK, which everyone does and after that there are no issues. Anyone have any idea why this is happening and how to fix? Thanks!

• Cannot establish ssh connection to computer on local network

  - by ovangle

  I've just (re)installed ubuntu 11.10 on my main pc, and the connection times out every time I try to ssh connect to my laptop (over the local network) to retrieve the files I backed up there. The connection times out every time I try to connect. I can establish a connection in the other direction without issue. Here's the verbose output I get when I try to connect: ovangle@ruby-EP43-DS3:~$ ssh -v [email protected] OpenSSH_5.8p1 Debian-7ubuntu1, OpenSSL 1.0.0e 6 Sep 2011 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to 10.1.1.4 [10.1.1.4] port 22. debug1: connect to address 10.1.1.4 port 22: Connection timed out ssh: connect to host 10.1.1.4 port 22: Connection timed out ssh is installed on both machines, and I've tried deleting '~/.ssh/known_hosts' on both machines, still nada. I've changed the sshd logging on the laptop to VERBOSE and restarted the daemon (because I wasn't getting any relevant syslog entries otherwise), and this is the log for the most recent connection attempt. EDIT: posted wrong logs last time. They just showed that there was a connection received, they weren't actually the sshd logs (which were in auth.log as I recently discovered). Unfortunately, that log is filling up with extremely weird error messages and it gives me no information about the connection.

• Firefox generating error?

• New SPC2 benchmark- The 7420 KILLS it !!!

  - by user12620172

  This is pretty sweet. The new SPC2 benchmark came out last week, and the 7420 not only came in 2nd of ALL speed scores, but came in #1 for price per MBPS. Check out this table. The 7420 score of 10,704 makes it really fast, but that's not the best part. The price one would have to pay in order to beat it is ridiculous. You can go see for yourself at http://www.storageperformance.org/results/benchmark_results_spc2The only system on the whole page that beats it was over twice the price per MBPS. Very sweet for Oracle. So let's see, the 7420 is the fastest per $. The 7420 is the cheapest per MBPS. The 7420 has incredible, built-in features, management services, analytics, and protocols. It's extremely stable and as a cluster has no single point of failure. It won the Storage Magazine award for best NAS system this year. So how long will it be before it's the number 1 NAS system in the market? What are the biggest hurdles still stopping the widespread adoption of the ZFSSA? From what I see, it's three things: 1. Administrator's comfort level with older legacy systems. 2. Politics 3. Past issues with Oracle Support.   I see all of these issues crop up regularly. Number 1 just takes time and education. Number 3 takes time with our new, better, and growing support team. many of them came from Oracle and there were growing pains when they went from a straight software-model to having to also support hardware. Number 2 is tricky, but it's the job of the sales teams to break through the internal politics and help their clients see the value in oracle hardware systems. Benchmarks like this will help.

• Facing a character towards the mouse

  - by ratata

  I'm trying to port a simple 2d top down shooter game from C++(Allegro) to Java and i'm having problems with rotating my character. Here's the code i used in c++ if (keys[A]) RotateRight(player, degree); if (keys[D]) RotateLeft(player, degree); void RotateLeft(Player& player, float& degree) { degree += player.rotatingSpeed; if ( degree >= 360 ) degree = 0; } void RotateRight(Player& player, float& degree) { degree -= player.rotatingSpeed; if ( degree <= 0) degree = 360; } And this is what i have in render section: al_draw_rotated_bitmap(player.image, player.frameWidth / 2, player.frameHeight / 2, player.x, player.y, degree * 3.14159 / 180, 0); Instead of using A-D keys i want to use mouse this time. I've been searching since last night and came up to few sample codes however noone of them worked. For example this just made my character to circle around the map: int centerX = width / 2; int centerY = height / 2; double angle = Math.atan2(centerY - mouseY, centerX - mouseX) - Math.PI / 2; ((Graphics2D)g).rotate(angle, centerX, centerY); g.fillRect(...); // draw your rectangle Any help is much appreciated.

• Backing up data (including mysqldumps) to S3

  - by seengee

  We have a web app on a number of servers and we want to add an additional layer of redundancy by backing up the key data to S3. The key data is the MySQL database and a folder containing dynamically created site assets - predominantly images. Some kind of rsync based solution would initially seem the best plan. A couple of years ago we played with S3cmd (in particular s3cmd sync) with some success but we didn't find it particularly reliable although this may have changed since. Its occurred to me though that a rsync solution might not work particularly well with a single db.sql file created with mysqldump and I assume this means the whole database getting transferred each time, with multiple databases of over 1GB this is going to add up to a lot of traffic (and $s) very quickly. With the image files I could simply just transfer files modified within the last day which would be far more simple. What approach should I look at?

• xubuntu 12.04 screen regularly stops refreshing, refreshing resumes after un-/re-maximizing a window

  - by user68477

  My screen frequently stops completely refreshing. I can make it resume refreshing by un-maximizing/re-maximize a window or by switching workspace (the un-/re-maximizing works every time. Switching workspace sometimes has to be done a couple of times). The immediate impression is that the system is frozen: there is apparently no reaction to anything I do but interestingly window title bar will change, if I switch application with (i.e alt+tab or browse through folders) I saw an identical issue in ubuntu 10.04, though a lot less frequent, I never saw this in ubuntu 12.04 (which I have been using the last 4-5 months). After switching to Xubuntu I'm seeing this again and more frequently. The specific reason I'm not sure this is a bug: I installed gnome-control-center which dragged in tons of packages. This was while trying to fix dual-screen setup. I believe the issue surfaced after this. I later meticulously removed every package from this batch (purge) in the hope that every setting would also be removed. But the issue has persisted. Another issue happened at the same time, it may be totally unrelated but it feels as if it is the same basic issue: the screen resolution of the greeter became less than the expected 1680x1050 and often after login there's just a blank and totally unresponsive wallpaper without panel so I have to force reboot. When the login is successful it's very clear that it works hard to determine the correct resolution which is achieved after a few blink to black screens. My questions: 1) Is this a settings issue or a bug? 2) How do I begin to research the issue - could I perhaps some way reset xubuntu/xfce to default. 3) If this is a bug where would be the most appropriate place report this?

• Transferring Postfix install to new computer

  - by mlissner

  I have postfix installed on one computer, with DKIM and SPF working properly. What I'd like to do is start using a different computer instead, with the minimal amount of fuss. Mail servers have a way of baffling me, but I know there are things with cryptography going on here that I don't fully understand (and I don't really care to - I figured it out when I set up the last computer about a year ago, and am happy not to delve into it again). Right now, I'm working on the early steps of this process -- installing postfix on the new machine, and getting it going. Are there specific steps I could take to move the correct configs and key files and such to the new computer?

• How to control messages to the same port from different emitters?

  - by Alex In Paris

  Scene: A company has many factories X, each emits a message to the same receive port in a Biztalk server Y; if all messages are processed without much delay, each will trigger an outgoing message to another system Z. Problem: Sometimes a factory loses its connection for a half-day or more and, when the connection is reestablished, thousands of messages get emitted. Now, the messages still get processed well by Y (Biztalk can easily handle the load) but system Z can't handle the flood and may lock up and severely delay the processing of all other messages from the other X. What is the solution? Creating multiple receive locations that permits us to pause one X or another would lose us information if the factory isn't smart enough to know whether the message was received or not. What is the basic pattern to apply in Biztalk for this problem? Would some throttling parameters help to limit the flow from any one X? Or are their techniques on the end part of Y which I should use instead ? I would prefer this last one since I can be confident that the message box will remember any failures, which could then be resumed.

• Dual boot Win/7 and Ubuntu 12.04

  - by Brian

  So I've always wanted Ubuntu along with windows 7 and finally I went to try and make my computer that last night. (( I'll just skip the long story. )) I loaded Ubuntu from CD, Version 12.04 and it loaded fine and then I clicked the install icon. It asked me witch option I would like to proceed with, and I answered Ubuntu, in Windows 7. So it did everything rather quickly, and restarted itself; upon restarting itself it ejected the CD, and I thought everything was good to go. It brought me to the Option to either load Ubuntu or Windows, I was thinking to myself wow that was alot easier than I thought; Windows 7 Loads fine after it checked the HDD but when I go to load Ubuntu it brings me to the loading screen and then stays there for a long period time, finally moves on as if it was going to load into the regular dashboard, but loads into a dos looking thing. (( I'm sorry if I sound retarded explaining everything I'm not great with computers )) And at the very time it says something like installation failed. It also says it could not find a file or something like that. If you need me to go back and get the full message and put it up here I will. But if I put the CD in it loads fine. Thanks in advance for everyone that helps me solve this problem.

• Apache CPU usage stays at 100% even when there are no requests

  - by Leirith

  Hi, I've been running the Apache HTTP server benchmarking tool (ab) on my new Apache server to test performance. I noticed that with a command like the following: ab -n 100000 -c 1000 http://www.mysite.com/ The CPU is used 100% by the apache2 processes during the testing. When the test concludes, usually with the following error just before the last requests are made: apr_poll: The timeout specified has expired (70007) Total of 99960 requests completed the CPU usage remains at 100%, and it's all being consumed by apache. I am using the worker MPM with and running PHP with mod_fcgid. Any advice as to why this is or what can be done to stop it would be appreciated.

• snort-mysql not starting on Ubuntu server

  I am following this tutorial: https://help.ubuntu.com/community/SnortIDS I've set up the database, everything has installed correctly, and I've configured the snort.conf file so it outputs to a database (with creds all filled out ok). When I run /etc/init.d/snort start, it fails but does not produce any error message other than [fail].
