• Netbeans hard freezes Windows XP, how to debug

  - by Jestep

  I get this problem about once to twice a day while editing in netbeans. I will be editing some code in Netbeans and I get a hard freeze requiring a full reboot. There hasn't been any correlation with an actual event that I can tell. Sometimes it's when I focus, sometimes while typing, sometimes while clicking on another window. I need to figure out how to track down what's causing the problem, as no error is generated when this happens. No error in Netbeans logs or Windows logs. I've also tried letting it sit to see if it recovers, and it's definitely stuck. I haven't had any problems with other apps running JRE, so I'm thinking it's Netbeans itself. I can't submit a bug report because I can't get a log or any reproduce-able explanation of the problem.

• Enlarge partition on SD card

  - by chenwj

  I have followed Cloning an SD card onto a larger SD card to clone a 2G SD card to a 32G SD card, and the file system is ext4. However, on the 32G SD card I only can see 2G space available. Is there a way to maximize it out? Here is the output of fdisk: Command (m for help): p Disk /dev/sdb: 32.0 GB, 32026656768 bytes 64 heads, 32 sectors/track, 30543 cylinders, total 62552064 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000e015a Device Boot Start End Blocks Id System /dev/sdb1 * 32 147455 73712 c W95 FAT32 (LBA) /dev/sdb2 147456 3994623 1923584 83 Linux I want to make /dev/sdb2 use up the remaining space.

• sharepoint 3.0 site restore/import trouble...

  - by Trondh

  Hi, We have some old sharepoint data (from a WSS 3.0 SP1 or SP2 install), that I need to restore. Problem is: This is a time management site, and one of the fields automatically pics up the user name of the user that enters data, and this is used to keep track of who worked when. Now, when I import this into my temporary sharepoint 3.0 server, these fields are blanked, and the creator of the element is replaced by my admin user (the account that ran the import job). So, to the question: Is there any way at all to grab hold of these data before the sharepoint import job "destroys" them? I'm using stsadm -o import. I don't care if I have to pick the database itself apart manually, I just need to know if it's possible to get hold of these fields with data intact from my export files... (Backup you say? It was deleted loong ago. This sharepoint export is all we have...)

  We have a application in Windows Server that download data from SQL server and store in our local machine. Now the problem I have is my Windows Server has two logins and in one login the app runs real slow, like gets 1 row in a minute, and from another login it fetches 20 rows in a minute. We have this problem only for a last couple of days. What could have caused this? More details: SQL server:S QL server2008 Os: Windows server 2008 Access method: Remote connection. Application: Custom .Net application to get data Both accounts are limited rights accounts. Any tools to track this? I am not sure what should I start with.

• Blocking facebook's Like button in firefox

  - by Quiark

  Many sites today use widgets from facebook such as the Like button, list of friends who are fans of that site and so on. While it may be a nice feature, I perceive it to be a serious privacy intrusion, because facebook most likely stores information about which sites you visit. I also heard that when you are not logged into facebook, it still tracks the sites you visit (probably with a cookie) and once you log in attaches the data to your real account. For now, I want to keep using facebook, but I would like to block just these widgets so it can't track me. Is there any Firefox extension which could do that?

• How to sync apps with one Mac and 3 devices?

  - by openfrog

  We have 1 Mac, with 1 iTunes account, and 3 iOS devices. Every time we sync one device, iTunes either spams it with ALL apps from ALL devices, OR it removes all of the apps from the device including all the data. Which is very annoying. Someone told me there is a way to tell iTunes to keep separate track of the devices. How can I setup iTunes such that it will not transfer all my iPhone-only apps to my iPad every time I sync? Basically I want the devices to be the "master". They give the direction which apps should be on the device, and not the other way around.

• Linux freezes every few seconds

  - by Zeppomedio

  We're having an issue where one our Linux boxes (Ubuntu 10.04 LTS, running on EC2 with a quadruple-large size, 68GB of RAM and 8 virtual cores with 3.25GHz each) freezes up every few seconds. Typing in an ssh session will freeze, and running strace on one of the Postgresql processes that's running usually shows: 02:37:41.567990 semop(7831581, {{3, -1, 0}}, 1 for a few seconds before it proceeds (it always gets stuck at that semop). OProfile shows that most of the time is spent in the kernel (60%) versus 37% in Postgresql. The result of these halts (which began suddenly a day ago) is that load on the box has gone from 0.7 to 10+, and causes our entire stack to slow done. Any ideas on how to track down what's going on? iostat doesn't show the disks being particularly slow or overloaded, and top shows user cpu % spike from 8% to about 40% whenever these back-ups happen.

• Connect macbook to my LAN through a VPN - best solution? [closed]

  - by LewisMc

  So I have a LAN connected via a ADSL/PPPoA, this is using a bog-standard DLink router supplied by my ISP (talktalk UK). I have a NAS within the LAN that is running FreeNAS and I want to be able to connect to it when I'm out and about. It's running an atom so it's quite low on juice consumption but I don't want to have it on all day and night so I've been waking it via a magic packet and booting it down from the web admin when I need it. So I want to connect to the LAN, I presume via a VPN, to be able to send a magic packet. But what is the best method to accomplish this, or is there an easier way? I've been looking at the cisco 857 integrated router and the Netgear prosafe 318(behind modem) but not sure If I'm on the right track with what I want to achieve as I've not much experience or knowledge with VPN's or networking (software engineering student). I have tried port forwarding but to no avail, either with magic packets or even connecting outside the LAN via DYNDNS. Thanks,

• How to keep programs from source up to date?

  - by wizard

  I'm designing a new server setup for hosting multiple websites. (Shared hosting for my clients over at SliceHost.) I've recently moved away from the traditional LAMP setup and chosen Ubuntu, Nginx, php-fpm and mysql. I like it a lot better then my old Apache, suphp, mysql setup. It works great, provided encapsulation between sites and uses substantiallly less memory. However I have one major maintenance problem. In order to have a recent version of Nginx and in order to use php-fpm I've had to compile these programs from source. The reason I see this as a problem is that keeping track of updates, and build configurations will end up being a lot of work. For two programs (and a patch) I can handle it, but it seems like this setup would not scale with many packages and servers. Are there good ways to manage this situation? I'm sure people do this all the time.

• Someone used my postfix smtp (port 25) to send spam mails to me

  - by Andreas

  This week, someone started to send spam-mails through my postfix-smtp access (I verified by logging in through telnet from an arbitrary pc and sending mails with any ids myself) on my server, with recipient and target being [email protected]. Since I have a catchall and mail-fowarding to my google account, I received all those (many) mails. After a lot of configuration (I lost track of what change did what, going through dozends of topics here and over the net) that hole seems fixed. Still, what hapened? Does port 25 need to be open and accepting for my catchall to work? What configuration did I do wrong? I remember the first thing I changed (that had an effect) was the inet_interface setting in main.cf, only later to find out that if this does not say "all", my mail to mydomain.com does not get forwarded any more.

• Cursor and selection invisible if focus is lost

  - by Alois Mahdal

  "Latest" versions of Excel (I think it's since 2007) have a new added "feature" that if Excel windows loses focus, the cursor becomes invisible. Also coloring of headers is default, so it's impossible to locate cursor and/or selection as soon as I switch to other window. This annoys the hell out of me as it makes Excel almost unusable for most of tasks I need it for: keeping track of test cases while performing testing in another window. obtaining data somewhere else and porting it to Excel (I have never seen such behavior in other applications and can't even think of a justification for it.) Is is possible to turn this behavior off?

• Is looking for Wi-Fi access points purely passive?

  - by Aric TenEyck

  Say I carry a Wi-Fi enabled phone or laptop through an area where there are WAPs. Assuming that I don't actively try to connect to them or otherwise interact with them, is it possible for the owner of that WAP to know that I was there? I'm asking this in the context of my earlier question: Looking for MACs on the network I was talking with a friend about my newfound ability to detect phones (and other devices with MAC addresses) on the network, and he pointed out that it might be useful to detect unknown phones on the network; I could use that data to track down anyone who was in my house and brought a Wi-Fi phone with them. So, if I set up a logging fake WAP with no security or encryption, can I glean any useful information about the devices that come into the house? Assuming that the thief doesn't actively try to connect...

• My servers been hacked EMERGENCY

  - by Grant unwin

  I'm on my way into work at 9.30 pm on a Sunday because our server has been compromised somehow and was resulting in a DOS attack on our provider. The servers access to the Internet has been shut down which means over 5-600 of our clients sites are now down. Now this could be an FTP hack, or some weakness in code somewhere I'm not sure till j get there. Does anyone have any tips on how I can track this down quickly. Were in for a whole lot of litigation if I dont get the server back up asap. Any help appreciated.

• C++ Serial Port Question

  - by Pfeffer

  Problem: I have a hand held device that scans those graphic color barcodes on all packaging. There is a track device that I can use that will slide the device automatically. This track device functions by taking ascii code through a serial port. I need to get this thing to work in FileMaker on a Mac. So no terminal programs, etc... What I've got so far: I bought a Keyspan USB/Serial adapter. Using a program called ZTerm I was successful in sending commands to the device. Example: "C,7^M^J" I was also able to do the same thing in Terminal using this command: screen /dev/tty.KeySerial1 57600 and then type in the same command above(but when I typed in I just hit Control-M and Control-J for the carriage return and line feed) Now I'm writing a plug-in for FileMaker(in C++ of course). I want to get what I did above happen in C++ so when I install that plug-in in FileMaker I can just call one of those functions and have the whole process take place right there. I'm able to connect to the device, but I can't talk to it. It is not responding to anything. I've tried connecting to the device(successfully) using these: FILE *comport; if ((comport = fopen("/dev/tty.KeySerial1", "w")) == NULL){...} and int fd; fd = open("/dev/tty.KeySerial1", O_RDWR | O_NOCTTY | O_NDELAY); This is what I've tried so far in way of talking to the device: fputs ("C,7^M^J",comport); or fprintf(comport,"C,7^M^J"); or char buffer[] = { 'C' , ',' , '7' , '^' , 'M' , '^' , 'J' }; fwrite (buffer , 1 , sizeof(buffer) , comport ); or fwrite('C,7^M^J', 1, 1, comport); Questions: When I connected to the device from Terminal and using ZTerm, I was able to set my baud rate of 57600. I think that may be why it isn't responding here. But I don't know how to do it here.... Does any one know how to do that? I tried this, but it didn't work: comport->BaudRate = 57600; There are a lot of class solutions out there but they all call these include files like termios.h and stdio.h. I don't have these and, for whatever reason, I can't find them to download. I've downloaded a few examples but there are like 20 files in them and they're all calling other files I can't find(like the ones listed above). Do I need to find these and if so where? I just don't know enough about C++ Is there a website where I can download libraries?? Another solution might be to put those terminal commands in C++. Is there a way to do that? So this has been driving me crazy. I'm not a C++ guy, I only know basic programming concepts. Is anyone out there a C++ expert? I ideally I'd like this to just work using functions I already have, like those fwrite, fputs stuff. Thanks!

• MySQL server simple insert/update/delete queries are taking a long time to execute

  We have a VPS hosting server with a MySQL server running on it. We host several databases for client's websites. Recently we have noticed that insert/update and delete queries are taking a long time to execute sometimes as close as 30 seconds. I use the following command to see these queries being executed: watch -n1 mysqladmin proc stat We have still not been able to track the root of this problem. I would apprecite if anyone had any pointers as to what we can check or improve to resolve the issue. Thanks

• Windows Vista Home memory usage problem [closed]

  - by lordg

  Hi, I have a Windows Vista Home laptop from a client that is running on 1GB ram. The laptop is used for super basic things, word, internet, outlook, etc. What makes zero sense is that the RAM is being completely consumed, causing the PC to hang sometimes when it can't take it anymore. However, in task manager, the processes appear to only be consuming maybe 100MB (Private Working Set). The client literally has a simple setup, and is running kaspersky, though that does not seem to be indicating it is the cause of the excessive memory usage. Does anyone have a suggestion on how to resolve the memory issue or how to track down what is actually happening and fix it? G

• Microsoft Office tracking license marks/keys in saved files (doc/docx/xls etc.)?

  - by pawel159

  Does Microsoft Office use any marks/keys in saved files, that can track the computer and software license using which file was saved? E.g.: I use Office at work and save files on pendrive. When I'm home I recall to check something and introduce little modifications. I'd save this file using MS Office Home and Student license, but at work I will be redistributing this file and it should look as it was saved at work, with company's license (not my private). Will saving it at work once again wipe license marks from home (if any exist)?

• IIS7 houndreds of connections in CLOSE_WAIT

  - by rjlopes

  I have a .Net application on my IIS7 server it was working fine until I had to move it to another server. I moved the exact same code to the new server and I noticed that after some hours the website stopped responding to remote requests but if I did remote desktop to the server it responded to the request done to localhost. If I stop the website and the application pool it started working fine again. I was able to track the problem to hundreds of requests left in CLOSE_WAIT state to the http port that are never closed (I waited a few hours and they remain the same). Any ideias?

• Warning popups that direct to 3rd party sites

  - by Kingamoon

  Lately, I've been getting warning popups on my browser (latest version of Chromium) that notify me that my Java version of current browser is outdated and needs to be updated. What's alarming to me is that it sends me to some sites I've never heard of like Malest.com. When I block a site, it redirects me to a different one. I don't know how to track what's causing these alerts. I ran Microsoft Security Essential and it found nothing. Any suggestions on what to do to nail down this irritating problem?

• Timing startup processes?

  - by acidzombie24

  My Windows 7 use to boot up fast and now its getting rather slow. I suspect one program is eating up all the time yet i cant tell what it is since task manager shows <40% of the cpu being used. What can i use to track how long each process takes when my computer boots/starts up? Note: Except for launchy which i used before my comp became slow, all my startup and services are all signed and known (broadcom, VMWare, Google Inc, Intel, etc) Note2: I am mostly considering the time it takes after i login but i suspect the time before that is slightly slower (i dont think very much though)

• How to get more info out of the uninformative Windows 8 BSoD?

  - by amiregelz

  Windows 8's Blue Screen of Death is different from the previous Windows versions' one: In order to find out what caused the problem you need to write down or remember the search term it presents you with. The two search terms I have seen suggested so far are SYSTEM_SERVICE_EXCEPTION and HAL_INITIALIZATION_FAILED. Both of them are quite generic terms. While it’s nice not to have to look at a blue screen full of text, the previous BSoD was more informative than the Windows 8 BSoD, since it contained a detailed error code (information for diagnostic purposes that was collected as the operating system performed a bug check), which could get you closer to tracking down the root of the problem. How can I get more information about the error Windows 8 has encountered, in order to track down the root of the problem?

Our goal is to create an auto-responder rule, or template that fires at sender. I have created a mail-enabled public folder, with owner permissions for each group member. I have also set up a rule template (response) and I am a little unclear as to the send as permission set, or where to set that up. Can someone please tell me if I am on the right track? Will I have to do each Outlook client machine (whole group!) the same?

• How can 2 or more instances of the same program to communicate in local network?

  - by user1981437

  I want to create program which will be in use for few computers connected in local network. Basically the program aim is to keep track of all tables in a bar ( lets say ), which are reserved. When some user book a table as reserved the program should broadcast the table number to all other Pc's and mark the table as reserved. Since all computers use the same program, how is possible to create communication between all of them ? Should i use sockets to achieve this? If it matters, all of the computers have installed Linux OS,and the app will be developed in ruby,perl or php. Thank you.
