• Context Menu for Browser to download file to specific folder

  - by elcojon

  There is this website which has customized audio files for me. I would like to save them in a special folder. Now I don't want to select the "special folder" each time in the file-chooser dialogue of my browser. I would rather prefer to have a custom entry in the context menu when I right-click the download link. This context-menu-entry should do the trick and download the file to the predefined "special folder". How would I start about that? I am using Safari and Chrome. So a solution in either browser is fine. To get into the context menu of the browser, what kind of programming do I need to do? Is it an extension, plugin, etc.? Thanks

• All terminal commands (like ls, cd, edit, open) are returning errors on my Mac

  - by park

  From what I can tell from reading other questions/answers is that my .bash_profile file may be corrupt. If I type echo $PATH in terminal the result is: /usr/local/git/bin From what I've read, that's not what the result is supposed to be. But I also can't get any of the commands (like edit or subl, for Sublime Text 2) to open the .bash_profile file to edit it. I was able to open the file in TextEdit using "cmd-shift-.", and here's what's in the file: [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" PATH=$PATH:~/bin export PATH export PATH=/usr/local/git/bin But the file is LOCKED, so I can't edit it there either. I'm very new to programming and in the middle of trying to install everything on my Mac to go through a Ruby on Rails tutorial. I can't even check my version of ruby, since even ruby -v returns -bash: ruby: command not found Any help would be greatly appreciated. Thanks.

• Dropbox.py on RHEL 6

  - by Timothy R. Butler

  I'm trying to run a headless install of Dropbox on RHEL 6. The daemon seems to be running, but when I try to use Dropbox's associated dropbox.py tool to control the daemon, it fails to run with the following error: Traceback (most recent call last): File "./dropbox.py", line 26, in <module> import locale File "/usr/lib64/python2.6/locale.py", line 202, in <module> import re, operator ImportError: /home/dropbox/.dropbox-dist/operator.so: undefined symbol: _PyUnicodeUCS2_AsDefaultEncodedString I'm running the current RHEL build of Python 2.6: root@cedar [/home/dropbox/.dropbox-dist]# rpm -qv python python-2.6.6-29.el6_3.3.x86_64 (I'm not sure if this would be better suited to Stack Overflow since it is on the verge of being a programming issue, but since I'm trying to use a program straight from Dropbox, I placed it here.)

• Can I write an Excel macro to find product info based on a SKU?

  - by GorillaSandwich

  My coworker wants to create an invoice template in Excel 2007. In column 1, he wants to be able to put in a SKU like '000293954'[1], and when he hits tab, have the other columns fill in a matching description and price. There would be a bunch of different SKUs and information. Has anybody done this type of thing with a macro before? Any advice? (I have programming experience with Javascript, PHP, and Ruby, but have never written a macro.) [1] The input wouldn't be typed - he'd use a wedge barcode scanner that inputs just like it was typed. Not that it matters for this question.

• How to write to a file and, while the file is still being writen, read and parse its contents using

  - by Isabelle

  Hello. I'm actually trying to write a shell script that logs the output of a command to a file but, since the command takes a long time to complete (about 15 minutes), I would like to start parsing the output of the command (content of the file) before the command is completed, so I can send messages to the standard output (the user), like: 10% complete 45% complete and so on. Program steps Redirect command to a file: $(command) $FILE Start reading and parsing the output ($FILE) before the command is finished. I thought of using pararell programming, but I havent't got the hang of it. Any help you be appreciated. Best regards.

• Is there any way to use devices like mp3 players when they are charging?

  - by GeoB

  The question is simple I think. All we have encounter gagets that they don't fuction while they are in charge, like cameras or mp3 players. But, we know that cell phones or laptops can have full function, when they charge with a charger, like USB connector. Is it in the programming? Why this happens? Can we change that with some device e.g. controlling the charging? I want to use a portable USB charger for my mp3, but I can't wait 3 hours for it to charge, because I cannot listen to music. It notices the charger, and gets in charge mode. Nothing functions until I unplug it. Thanks a lot

• Find & Replace in blogger

  - by Benjol

  (I just learnt that Yahoo are shutting down Geocities, this is a bummer as I used my account there to host two icons, in the days when Blogger didn't upload gifs. Now those two icons are referenced in every one of my 600+ posts). Blogger doesn't have a "Find & Replace in all posts" function. I'm wondering about using the API to hack something together, and wondered if anyone has already tried playing with the API, if there are any tips or things to avoid. Also if there isn't a sneaky shortcut (like switching to ftp, doing the replace locally then switching back?). Not 100% programming related, please be lenient, or at least answer my question before closing it!

• Any limitations for putting an SSD in a Mini? How fast would an external HDD be via Firewire? Is Ser

  - by Cyrcle

  I'm considering getting a Mini for web programming. I do a lot of text searches so I want to put a SSD in it. Does the Mini have any limitations that might effect the performance of a SSD? I'm trying to decide if I should get a Mini Server. I'd like to be able to have two internal drives so one can be SSD for OS and the code I'm working on, and the other can be my storage drive. However, I'm not sure if I'll be using the extra functionality of the server edition OSX or not, so I'm reluctant to pay the $200 premium. In a "regular" Mini I could put the SSD internal and use an external big drive, but would the external drive be fast enough via Firewire? Thanks in advance for any info.

• How to invoke a command using specific proxy server?

  - by Xiè Jìléi

  Some applications support proxy (http proxy or socks proxy), and some are not. For browsers, I can specify proxy server in the preferences/options dialog, and other applications may be able to configure proxy servers in config files. For general purpose, can I invoke a command using a specific proxy? Like following: $ proxy-exec --type sock5 --server 1.2.3.4:8000 -- wget/ftp ... I'm using Ubuntu Maverick. P.S. In win32, it can be implemented by hijacking the socket dlls, maybe, I'm not familiar with Linux programming, but I guess it's possible in Linux. though.

• Can a Mac Mini Server and XCode be used for multiple students?

  - by twerdster

  I'm not an administrator but Ive been given the task of finding out whether this is possible. The scenario is like this: At our university we are offering a course in basic iPhone programming for between 4 to 8 groups of students. We have a few iPads, iPods and iPhones but only two Mac Minis. We want to enable the students to work on XCode in the lab (and from home if possible) without buying 8 Mac Minis. Is this possible to do using a Mac Mini Server? If so how would it work if 2 or more groups want to use XCode simultaneously and to debug their programs on devices simultaneously?

• Graphic Setup tune-up checklist

  - by Click Ok

  I was trying to play the game Warzone 2100 and the games runs fine, with nice speed, but the screen stays with a horizontal lines "flickering"... My PC have a integrated GeForce Go 6100 vga. Ok, not a powerfull vga, but it's not the end of the world to run a "simple" game like this (compared with another games that ask you send your eyes to purchase a expensive vga). So, I think that the problem can be of the configuration of my machine. I use it in first instance for programming jobs, so I underpay attention to video setup. I would like about a checklist to know if my PC is "ready" to games. By example, I know that I need: Lastest vga drivers Updated DirectX and OpenGL What you suggest? There is too some good programs to test performance and suggests improvements in the system? Thank you! PS: I'm using Windows 7

• Syncronizing XML file with MySQL database

  - by Fred K

  My company uses an internal management software for storing products. They want to transpose all the products in a MySql database so they can do available their products on the company website. Notice: they will continue to use their own internal software. This software can exports all the products in various file format (including XML). The syncronization not have to be in real time, they are satisfied to syncronize the MySql database once a day (late night). Also, each product in their software has one or more images, then I have to do available also the images on the website. Here is an example of an XML export: <?xml version="1.0" encoding="UTF-8"?> <export_management userid="78643"> <product id="1234"> <version>100</version> <insert_date>2013-12-12 00:00:00</insert_date> <warrenty>true</warrenty> <price>139,00</price> <model> <code>324234345</code> <model>Notredame</model> <color>red</color> <size>XL</size> </model> <internal> <color>green</color> <size>S</size> </internal> <options> <s_option>some option</standard_option> <s_option>some option</standard_option> <extra_option>some option</extra> <extra_option>some option</extra> </options> <images> <image> <small>1234_0.jpg</small> </image> <image> <small>1234_1.jpg</small> </image> </images> </product> </export_management> Some ideas for how can I do it? Or if you have better ideas to do that.

• Windows terminating system processes

  - by jemper

  To be sure nobody will answer me with advice on not trying to terminate critical (system) processes - I'm relatively experienced in programming and Windows in general - I'd know what I'm doing so far. So there are these processes that can't be terminated with taskkill - system processes in general. But there also is, for example my Anti Virus program that makes itself "unterminateable". How can I access and mainly terminate system processes under windows? (kill.exe by Microsoft doesn't work) How do processes like anti-virus programs protect themselves? How can you turn them off again, then?

• copy files created in one folder to multiple other folders on linux

  - by Keith

  I'm looking for a way to copy photos that are uploaded to one folder to many other folders and visa versa. Example: a photo is uploaded to folder 1, it is then copied to folders 2-5. And if a photo is uploaded to folder 2 it is copied to folders 1 and 3-5. I'm running CentOS 5. All of these folders are on the same server. I came across another post on here that talked about incron, but that type of programming is over my head.

• Complete machine freezes...at a loss

  - by user28818

  Guys, We built around 12 machines a few months ago to run Ubuntu. They each have the following specs: ASUS Z8NA-D6 motherboard Dual quad core Intel(R) Xeon(R) CPU E5520 @ 2.27GHz OCZ Mod Extreme Pro 500W power supply 12 GB Kingston RAM Nvidia GeForce 9800 GT graphics card My machine ran well for awhile. However, it started experiencing random lockups. These lockups are not X lockups, they are complete system freezes. The nic stops responding, the magic sysrq buttons won't work. The machine is dead. I first suspected RAM. Memtest86 didn't find anything, but I replaced the RAM anyway. Still, lockups. So I replaced the graphics card. Still, more lockups. They became more and more frequent and started to happen 2-3 times a day. So I replaced the motherboard and power supply in one fell swoop. Suddenly, no more lockups! Woohoo! Except, a week later, in the morning, the machine wouldn't wake up. I reset it, started it up, and the log files showed the last entry at around 11 pm the evening before. This has started occurring with more frequency...now just about every morning I come in, the machine is locked up, and has been since the night before. Yesterday, in the 3 weeks since I replaced the motherboard and power supply, the machine actually locked up on in in mid-work. This is the first time since replacing the two (MB and PS) that this happened while I was using it. All others occurred while I was away. I'm at a loss. Nothing is in syslog or message that would indicate a problem around the time of the lockup. Temps are good...I use lmsensors to monitor and have a script that writes the output to file every minute. They never get that high. The only thing I haven't replaced at this point is the case and the harddrives. I doubt either could be the cause. What would you do if you were in my shoes? Is there a troubleshooting approach I'm missing? For the record, all of the other machines, all eleven of them, don't have any problems. They're all running the same version of Ubuntu (Lucid) that I am. Thanks!

• What is the probable failure - no BSOD, no event log, monitors sleeping, force reboot required

  - by Tyler

  Every 3 to 15 days, my PC freezes. This typically happens when the computer is idle, I'm coming home from work, back from vacation, etc. It's never happened while using my computer. The monitors are in power save mode The Caps Lock light on the (wireless) keyboard doesn't work Ctrl-alt-del has no effect, mouse (wireless) has no effect The hardware reset button and single press of power putton have no effect Computer does not appear on the network No BSOD, no memory dump Event logs have no errors or indications of problems near the time of crash. Only messages after reboot indicating that there was a reboot without a clean shutdown. Windows is set to never put the computer to sleep (just the display) Here are the vital stats of the build: OS Windows 8 Pro 64-bit CPU Intel i5-2400 Mobo Intel BOXDP67DE Micro ATX GPU MSI N460GTX Cyclone768D5/OC RAM CORSAIR XMS3 8GB (2 x 4GB) CMX8GX3M2A1333C9 PSU SeaSonic X Series X650 Gold System Drive Samsung 840 Pro 256 GB SSD Data Drive 2 x Western Digital WD20EARS 2TB in hardware RAID 1 Optical Lite-On DVD burner IHAS424-98 And here is the story of how the problem developed and what I've done to diagnose: January 2011, system built with Windows 7 64-bit, runs great. March 2011, Intel replaced the mobo because of the bad sata controllers. October 2012, upgrade to Windows 8 (problems start shortly after). January 2013, system freezes and causes network to fail for the whole house. Unplug the network cable and other devices and PCs can use the internet. Plug it back in, internet goes away for everyone. Reboot and everything is fine. March 2013, install Intel Gigabit CT PCI-E NIC, disable mobo nic in bios. Network strangeness goes away. Freezes are less frequent. Memtest shows no problems (20 passes). Early June 2013, replace Antec PSU with SeaSonic PSU. Mid June 2013, replace OCZ Vertex 2 SSD with Samsung SSD. Late June 2013, get frustrated and hope the community has some good ideas (I'm running out of budget to replace parts). My next plan of attack is setting "Turn off display" to Never and using a screen saver to see how that reacts on the next freeze. It makes me sad to waste power for up to 15 days though. Has anyone out there seen a problem like this? Any ideas on what kind of malfunction would act this way? Ideas of other diagnostic steps to take?

• [Linux] Bind/map Character to alt+[some key]?

  - by Paul

  OS: Ubuntu In programming and various terminal programs (Screen, Vim) the [, ], { and } tends to be used a lot. I'm using a Norwegian keyboard where these are placed such that I have to stretch my fingers a bit too long for whats comfortable. To make it easier I though I'd try to make alt+[some key] be one of these characters. Is there a way that I can bind, say alt+æ (Norwegian letter) to '{' system wide? Btw, is such thing called binding, mapping or something else? I'm getting a bit confused by the terms... :)

• How's the latency with Mac VNC on Windows PC using a crossover cable?

  - by Vadoff

  I use a Windows 8 PC as my main system, and do some programming with Xcode which I use a virtual machine for. However, it doesn't run as smoothly as I would like, so I'm thinking about purchasing a Mac Mini. My question is if I connect my PC to the Mac Mini directly (via crossover cable, firewire, or usb), would I be able to control the Mac using VNC with almost no latency? If not, is there any other way I'd be able to use both my PC and the Mac Mini simultaneously (using the same peripherals)?

• Windows 8 disk errors

  - by wrongusername

  So yesterday, I forcibly restarted my Windows 8 PC. VMWare Workstation was having some trouble with the guest Linux Mint OS. It wasn't responding for some time, so I tried suspending it September 28th or perhaps even before. It wouldn't suspend -- I forgot what the window looked like, but all options in the power menu were disabled (i.e. "Shutdown," "Power Off," and options like that were all disabled). I eventually killed the VMWare application through Task Manager, though I was too lazy to hunt down the running virtual machine itself, and decided to kill it by just shutting down my PC entirely. The PC wouldn't shut down for quite some time after the monitor went blank, so I did a cold reset by holding the power button. I then powered it on again and Windows briefly gave me some message like "Search for KERNEL_STACK_INPAGE_ERROR." Windows then started diagnosing some problems and gave me the message, "Repairing disk errors. This might take over an hour to complete." That was yesterday night, and I went to sleep without waiting for it to finish. This morning, it said that the repair failed, and that the log was at C:\windows\system32\LogFiles\srt\srtTrail.txt (as I remember it -- I don't have the exact path I wrote down right now). It gave me some other options to troubleshoot, such as resetting Windows (files and settings still intact, but programs not installed through the app store will be erased). That didn't work (no error message given, I was just told it didn't work). I tried rebooting in safe mode, the same diagnosis process begins, except that this time it doesn't bother with the automatic repairs again. So I tried using the command prompt to try to see if my files are at least still there. I was on the X drive, and I couldn't cd to the C drive. I couldn't find my folder under Users (of course?), and couldn't find the srt folder under LogFiles either. I am not sure what to try next. I have backed up everything, but to the cloud, so if absolutely necessary I can start off with a fresh copy of Windows and restore all my data, though it would be a hassle. Any thoughts on what might be wrong or what I can try? My computer was purchased just this June, so the hard drive should still be pretty new.

• Help looking before I leap! I need expert guidance...

  - by Ellen Reddick

  27" iMac running win7 under bootcamp (slick! ). I have Access 2003 program with files linked through ODBC used by 4 installations (all with Access 2003 installed). I want to buy Access 2010 and try it under virtual PC (under Bootcamp). Will it work (since I have to install the ODBC drivers)? If I decide after this trial that I like what it does, can I then install it under the Windows 7 bootcamp partition (with or without uninstalling the virtual PC) without using up the 2nd allowed installation? Also, I see that MS allows an Office Pro 2010 trial download good for 60 days. Would this work in Windows 7 Virtual PC and would it be a better way to go, followed by a legitimate purchase of Access 2010 for the Windows 7? This is not an Access programming question--I realize there may be some tweaks necessary in the program to run it under 2010 and I can handle that part.

• Search for specific call in asterisk log files

  - by chiborg

  In my Asterisk log file, I have a line like this (truncated): Executing [123@mycontext:1] Set("SIP/myhost-b7111840", "__INCOMINGCLI=4711") Now I want to do the following filtering while looking at the log file with tail -f: Match lines with a specific value for "INCOMINGCLI", storing the call ID (the "SIP/myhost-b7111840" part) Output all subsequent lines that contain the call ID. As a bonus, having a grep-like option like -A would be nice. I could do that easily in various programming languages, but how would I do it with standard UNIX commands like sed or awk? Can it be done with these commands?

• Computer Invisible On Domain

  - by Giawa

  Good afternoon, I'm sorry that this isn't a programming question specifically, but stackoverflow has been great at answering questions in the past, so I thought I'd give it a shot. One of our Linux users attempted to install Cygwin on our Windows Server 2008 Domain Controller. Now it is no longer possible to browse the domain and see all of the computers. For example, \\my_domain_name will just bring up a username/password dialog box (that will not accept any username or password, even the domain administrator) and no computers will ever be listed. However, I can still connect to computers based on their name or IP address. So \\eridanus or \\192.168.1.85 still work to connect to the shared directories of computers on our network. Does anyone know where I can find these settings? and how I can fix this problem? Thanks, Giawa

• iTunes and Hulu Playback Choppy and Slow?

  - by Bart Silverstrim

  Specs: Windows XP, latest updates 1.7 ghz Pentium 4 1 gig ram DirectX 9.0c NVIDIA GeForce FX 5200 with 256 meg RAM OpenGL 2.1 The story: Okay, I had an older system laying around that I figured I would try turning into a mini-media system to connect to our TV. I put together a lot of older parts, got it into working order, etc. and hooked it up and voila'...slower, but usable system that displayed to the TV. It could run some things decently. I put in iTunes, it played video okay. Not great, but okay. Played Hulu and since we have a 1Mb download rate, the minimum for their site, there were some choppy moments when watching their shows, but I found that (sadly) changing resolution to 800x600 seemed to help with the issue when running full screen. I downloaded the application called Boxee and installed it. It wouldn't run; apparently the video card in the system supported OpenGL 1.2, and needed at least 1.4. I bought a cheap card, the 5200, with four times the memory in it and support for OpenGL 2.1. Installed, everything seemed fine. iTunes seemed to run fine, the video driver (PNY video card) came with OpenGL 2.1, and Boxee finally ran. I then upgraded to the latest drivers for the video card and ran the DirectX updater from MS. After that, the OpenGL Extension Viewer wouldn't run. It just stayed as an icon in the task bar. Also, any and all videos in iTunes stuttered and went out of sync horribly. Unwatchable. I tried watching Hulu video in Boxee, and it displayed video like it was a series of stills in a very bad powerpoint. Playing straightforward audio-only came through fine, no stutters no hiccups. I tried system restore to roll back updates to pre-directX updates (I thought that seemed to be the time that triggered the weird behavior), no joy. I tried uninstalling and reinstalling the video drivers. I installed updated audio drivers (ensoniq audiopci), nothing helped. I finally wiped the drive last night and tried reinstalling everything and restoring my iTunes content via an import from a backup. Fresh install, no updater on the video card or directx. the problem was still there although I haven't tested Hulu, the iTunes player is still stuttering like crazy if I play video, fine if I play audio. I know the processor isn't high in heft, but with one gig of RAM and the fact that it seemed to do okay before I thought that the problem must be software related. Has anyone else run into this sort of issue and have a solution other than "buy a new computer"? What specs seem to work with video at the low end for you? Right now the system is of little use other than keeping my music library and iTunes apps synced with my iPod.

• **Simplest** way to dual boot Linux on a Vista laptop

  - by user20285

  I have a 64bit Vista laptop with no cd drive (and no intention of buying one). What is the simplest way (if any) for me to dual boot Linux (I don't care what version as long as it's not too old...and will run Ruby 1.8.7 or greater)? I'd prefer anything with an installer. I've been programming on Windows for a little over 1.5 years and would like the option of using Linux. I'm not a moron, but the I'm legitimately scared of messing up my computer. I speak the language of Rails, not of OS tweaks. Thanks!
