• Count total file size of many files in Windows

  - by user105249

  When I want to burn a CD R with lots of files, I have to make sure the total file size in my folder doesn't exceed the capacity of the disc (680MB). In Windows are there possibilities to check the total file size of a bunch of files. I put them in a folder, right-click and check the properties. But this is an annoying trial and error kind of way. Either there are too many files in the folder, or too little. I watch the file size go up as I keep selecting more files, using ALT+going down button. No. 2 is my favorite way to do it. Here's my question: For some reason Windows (I still use XP) only shows the total file size of 100 selected files. When you select more than 100 files, no file size information appears any more. Is there way, a trick, an app, to work around this problem?

• Getting around the FAT32 4GB file size limit

  - by Aesir

  I recently purchased a 32GB USB 3 stick that was formatted FAT32. I plugged it into my computer and attempted to copy a film onto it, the file was over 4GB however and it would not let me copy the file across because of the 4GB file size limit imposed by FAT32. After some googling I found that I could format my USB stick to have an exFAT format which would mean I could put files onto the stick greater than 4GB in size and the drive would work on both my Mac and my PC. The problem with this solution is that my PS3 cannot detect the USB stick when it is formatted with exFAT. I would like to know if there is a way I can have my USB stick formatted so it can have files greater than 4 GB and work on my PC, Mac and PS3.

• Active node stops resources when pasive node is shutdown

  - by Wakaru44

  2 nodes, active/pasive. 2 resources, a virtual ip, openLdap, and the nfs mount where openldap saves the data. When both nodes are up, things worked fine. You could move resources away and put the active in stanby. But when i rebooted the passive node, ( with the resources in the active node), and the passive node loses conectivity, all the resources in the active where stopped by pacemaker. I'm reading the documentation right now, but I just need a little quick tip to figure what could be hapenning here. Im using: corosync pacemaker RHEL 6

• Upgrade went wrong, laptop essentially 'bricked'

  - by hexagonheat

  I have an old netbook I was trying to upgrade from 10.04 to 10.10. Ubuntu was in the process of upgrading when everything completely froze. I left it sit for an hour but it would not respond to anything. So I powered down the machine and it didn't have the necessary files to run Ubuntu. I went to the terminal and it told me to put in some command that I can not remember to 'rebuild' something. That takes me to now, when I turn on the laptop it comes up with a screen "GNU GRUB version 1.98+20100804-5ubuntu3.3" and has a bunch of options such as: 1. Ubuntu, with Linux 2.6.35-32-generic 2. Ubuntu, with Linux 2.6.35-32-generic (recover mode) etc. (there are like 15 of these with different numbers after 2.6.35 and the word 'generic'. It doesn't seem to matter what I pick, it will go to the "Ubuntu" loading screen with the colored dots but then every time it will freeze and I have to reboot to the same thing. I can't seem to get a terminal prompt anywhere either. Any ideas? I can't think of what to do :(

• Can't bring NAT to work

  - by user31738

  Hello, I bought a D-link DIR-300 wireless router and i can't bring NAT to work, i have an ssh and http service i need to forward to the internet. My connection is as follows: I have an ADSL connection, i'm using a ADSL ethernet modem connected and working, it doesnt let me put it on bridge mode. I have my router connected to my adsl modem through ethernet, it gets its ip through DHCP (and i'ts always the same) I have a desktop computer running linux with apache and openssh configured and working, it has fixed ip. I configured the NAT in the modem forwarding port 22 from the router ip to the internet. In the router i setup NAT forwarding port 22 from the desktop computer fixed ip to out there. This setup already worked with a fonera i had before, can anyone help me with this or tell me what kind of tests do i need to do? How can i test if the router is forwarding ports correctly before the modem?

• Which programming language should i choose? (much more info inside) [closed]

  - by Andreas

  I am not completely sure if this is the right place to put this question, but since it's the programming thread I guessed that there's many experienced programmers here. :) Ok, hello! My name is Andreas and I am a 16 years old guy from Norway. For some time now I've wanted to learn a programming language. Six months ago I started learning C++, but quit withing a week due to lack of motivation. The same thing happend only 2 months ago when I tried to learn Lua. I wanted to program mods to the game Garry's mod, and was really motivated. Then I stopped playing the game, and the programming stopped with it. Today though I am ready again. The only difference is that I am not completely sure what I want to do with the language. I only want to create something, and I miss the progress of failing and enduring hard work until I finally solve the problem I've worked on for hours. What I am trying to say is; Is there any program out there that allows me, a complete noob (I didn't learn that much in a week, so I like to call myself a beginner), to create apps, mods or something similar but at the same time being qualified as a first time language? I was thinking of Java, because Android, Minecraft and many other applications and games use it. But I've heard that it is going to be replaced by a program called HTML 5 (whatever that is), is this true? I certainly don't want to spend many hours of my life on something that is useless in a year or two. Hopefully I didn't make this too complicated. I know that it is hard to recommend something when I don't have a goal, but I really don't know what to say. Have a good day kind folks! - Andreas EDIT:* I did not know that this was an off topic question, really sorry!

• I used a 301 Permanent Redirect to a 3rd party site by mistake! Can I stop the redirection?

  - by Dees

  Oh Noes! I've been parking a domain name for a friend/client of mine on my hosting provider (Dreamhost, FWIW) for a while, and they eventually asked me to redirect their domain to a 3rd party website which is currently featuring some relevant promotional content. Once this period ends, we will probably go ahead and set up a proper website for the domain on my hosting account. I used Dreamhost's "redirect" hosting option in their domain configuration panel, not realizing that it would implement a 301 Permanent redirect, or what the implications were. Now it seems that for any client that has visited the site anytime recently, the 301 redirect is still cached/in effect, although I have changed the domain settings back to regular Dreamhost full site hosting. It seems that the only thing that can be done is to wait out the TTL/cache expiration for the redirect. I have no idea how long that might be, so I'm wondering if there is any good way to cache-bust the redirect or otherwise undo its long-term effects. I put a simple html meta refresh in the domain folder to replace the 301 to keep the intended functionality in place, but I'm still not able to access the domain's other content normally, even via FTP, etc. Isn't there anything I can do? Otherwise, how long does it take for a cached redirect to expire? It's gonna be a bummer if it's really permanent.

• Mount "Macrium Reflect" on a partition, boot from there ?

  - by b e

  Can Macrium's Reflect recovery CD be mounted/used with GRUB ? If the cd can be 'put' (loaded/mounted/...) in a partition, then the only disc needed would be the actual recovery disc, which could be on an external hard drive, or even on the same machine in another partition, thus allowing on to recover using only what's on the machine itself. I have WXPpro and Xubuntu8.04 double mounted, really happy with them together, use each right now to fix problems with the other when they come up. Also have a partition for the Reflect CD, but I just can't get it to load from Grub, which would be great... Thanks for any thoughts, probably someone has already done this I know !

• increase performance of virtual machines on the 27" imac

  - by evan

  I'm using a 27" iMac (i7, 8GB RAM) at work and normally run two or three virtual machines at the same time, which hurts the performance of each virtual machine. I've learned on these forums the best way to increase virtual machine performance (aside from RAM) is to have them running on a separate hard drive from the one the OS is on. Of course with the iMac you can only have one hard drive and not even an SAS or solid state drive (well you could probably take it apart and put one in yourself but I wouldn't be permitted to do that). That being said, do you think it would help to run one or more virtual machines from a firewire external drive (or a usb 2.0)? Thanks for your input!

• Protect apache pages by URL

  - by Thomas

  Is it possible to allow access to specific URLs only to certain networks? Basically, I would like to restrict access to the admin area only to the local network This area's pages are prefixed by /admin Essentially, I would like all /admin/* to be forbidden from public access. Can apache handle such a case? Thanks UPDATE Using your suggestions I came up to <LocationMatch admin> Order allow,deny deny from all Allow From 192.168.11.0/255.255.255.0 </LocationMatch> However, I get 403 even though I am on the network. Additionally, if I put apache behind haproxy, is this going to work? Because the traffic will be coming from 127.0.0.1 to apache

• Conditional blocks of code in linux bash

  - by Arek

  Nearly everybody knows very useful && and || operators, for example: rm myf && echo "File is removed successfully" || echo "File is not removed" I've got a question: how to put a block of commands after && or || operators without using the function? For example I want to do: rm myf && \ echo "File is removed successfully" \ echo "another command executed when rm was successful" || \ echo "File is not removed" \ echo "another command executed when rm was NOT successful" What is the proper syntax of that script?

• Do we have enough time to build an electric car future?

  - by julien.groues

  A recent article from Greenbang has posed the question 'Do we have enough time to build an electric car future?'. The writer discusses that, although the future of transport might lie with electric cars, there is concern regarding whether we'll be able to build the market and infrastructure required to support them, before carbon and oil constraints create difficulties in powering the vehicles. Of course, the increasing use of Electric vehicles (EVs) is going to put excessive pressure on energy grids, as large volumes of electricity will need to be directed to charging points, which in turn must handle fluctuating demand at peak times. EVs are increasing in popularity as a sustainable method of transport to reduce carbon consumption, and electric utilities will have the opportunity, and the challenge, to quickly determine the best methods to fuel these vehicles and accommodate the associated increases in demand for energy. Critically, efficient software is required to provide diagnostic and predictive capabilities related to EV refuelling - for example, anticipated electricity flow will need to be addressed as the number of EVs on the road increases, and electricity will need to be directed to specific areas on-demand as vehicles attempt to recharge en-mass. But a smart grid infrastructure can meet these demands, intelligently. The implementation of a smart grid is not in the distant future, it is an achievable reality for utilities via simple installation of new software and technologies, which can be done incrementally for those facing existing legacy systems or concerned with upfront costs. The smart grid is integral to the monitoring and control of energy use as well as the future-proofing of the energy grid. A smart grid will be critical to meeting the electricity requirements of new EVs and will ensure their successful deployment by providing a reliable foundation for the data handling required to record and manage electricity distribution - from recording and assessing energy usage, to analysing data and sharing information with consumers via green billing. http://www.greenbang.com/do-we-have-enough-time-to-build-an-electric-car-future_14248.html

• How to fix the boot set up?

  - by Chris

  I got two OSes in my PC, Ubuntu and Windows 7. Until yesterday Windows 7 was on top of my dual-boot menu list, but I wanted to change it, so I went inside Windows configurations and put Ubuntu first, but I also set the time to 0 because I thought I could access Windows through Grub. But what happens is that after I upgraded Ubuntu to 11.10, that screen with boot options don't show Windows 7 anymore. I went online searching for a solution to my problem, most of them told me to configure some Grub options and others to use programs to do it. I've done them all and still can't access Windows 7. Just in case my problem is not clear yet, this is how was my boot order before I messed it all up: Windows 7 Ubuntu with a time of 10 secs to choose between both. This is how I wanted it to be: Ubuntu Windows 7 with 0 time to choose, but, inside Ubuntu I could access Windows through that Grub screen. But this is what happens: Ubuntu Windows 7 0 time, so it don't let me choose anything and jumps inside Ubuntu then inside Ubuntu grub doesn't show up anymore (black screen) and it starts Ubuntu normally. I tried to fix this many times from different ways inside Ubuntu but nothing worked, also when I try do something and then upgrade my grub with sudo upgrade-grub it shows this message: Generating grub.cfg ... Found Windows 7 (loader) on /dev/sda1 Skipping Windows 7 (loader) on Wubi system Found linux image: /boot/vmlinuz-3.0.0-12-generic Found initrd image: /boot/initrd.img-3.0.0-12-generic Found linux image: /boot/vmlinuz-2.6.38-12-generic Found initrd image: /boot/initrd.img-2.6.38-12-generic done Thats why in the title I said it could probably be my WUBI messing all up. Anyone heave a solution for this? Do you need more information? I have a netbook so I cannot use the Windows Repair CD.

• How can I disable logging in Tomcat 7?

  - by WilliamMayor

  I have a Tomcat 7 server running in a VM that has very little disk space (20G). Over the course of a few days Tomcat will fill the space with logging info (usually about 15G before it runs out). I've tried turning down the log level (from INFO to SEVERE) in the logging.properties file, I've also tried sending the log info to /dev/null. It doesn't seem to work as I still get a full log directory after no time at all. Can I put a file size limit on the log files? Is something overriding the properties I'm setting? Where can I find this information? My Google Fu just returns information about logging from within an application using JULI.

• canvas tile grid, hover effects, single tilesheet, etc

  - by user121730

  I'm currently in the process of building both the client and server side of an html5, canvas, and WebSocket game. This is what I have thus far for the client: http://jsfiddle.net/dDmTf/7/ Current obstacles The hover effect has no idea what to put back after the mouse leaves. Currently it's just drawing a "void" tile, but I can't figure out how to redraw a single tile without redrawing the whole map. How would I go about storing multiple layers within the map variable? I was considering just using a multi-dimensional array for each layer (similar to what you see as the current array), and just iterating through it, but is that really an efficient way of doing it? Side note The tile sheet being used for the jsfiddle display is only for development. I'll be replacing it as things progress in the engine. I hope you can help! Hopefully you guys can help me, I've been struggling to get through things, since I'm learning how things kind of stuff works as I go. If you guys have any pointers for my JavaScript, feel free. As I'm more or less learning advanced usage as I go, I'm sure I'm doing plenty of things wrong. Note: I will continue to update this post as the engine improves, but updating the jsfiddle link and updating the obstacles list by striking things that have been solved, or adding additions. Thanks!

• How can you achieve and maintain flow while pair programming?

  - by bizso09

  Flow is a concept introduced by Mihaly Csikszentmihalyi; in short, it means to get into the "zone". You feel immersed in your task, focused; the task can be difficult but challenging at the same time. When people achieve flow their productivity shoots up. Programming requires a great deal of mental focus because we often need to juggle several things in our minds at once. Many like to work in a quiet environment where they can direct their full attention to the task. If they are interrupted, it may take several minutes or even hours to get back into flow. I understand there's a practice in agile development and extreme programming called pair programming. It means you put the whole software development team in one room so that communication is seamless. You do write code with your pair because this way you get instant code reviews and fewer bugs get through. I've always had problems achieving flow while doing pair programming because of constant interruptions. I'm thinking deep about an issue then all of sudden someone asks me a question from another pair. My train of thought is lost. How can you achieve and maintain flow while pair programming?

• HP Probook 6550b has issues with an external monitor

  - by chama

  I recently got a new HP Probook 6550b laptop for work. However, very often, when left alone (not put to sleep), the built in display will go dark. Not only that, but whenever I plug in an external monitor, the display will blank out as well. Sometimes after this happens, putting the laptop to sleep and then waking it up solves the problem. But only sometimes and only for a short time. The next time I plug in my monitor, it happens again. I know this isn't only my problem - 6 other people got the same laptop as I have at the same time, and we're all having such issues. Any suggestions as to the root of this problem and a way to fix it? It's driving me crazy!

• User accounts in FTP

  - by Brad

  I have an FTP server(proftpd on debian) that I'm going to allow a couple friends access to, and I want some safety nets in place, just in case. These are some of the things I'd like to do: Jail the accounts to their home directories and impose a cap on the amount of data they can upload Allow them access to a shared folder(via symlink or something) where they have full access(Also with a storage cap, but larger) Allow my own account full access to the system(Using groups I guess) Not allow anonymous access, or allow it with its own folder, separate from the shared user folder Currently, I've got the accounts set up and jailed, but it seems like the symlink that I put in is not allowing them to visit the shared folder. I suppose this has to do with them not having read permissions anywhere but their own home directories, or maybe it's something else, I'll continue to look into it and provide any information that is requested. Is what I'm trying to do possible? Any tips or resources that you can share are appreciated. Thanks.

• Versioning APIs

  - by Sharon

  Suppose that you have a large project supported by an API base. The project also ships a public API that end(ish) users can use. Sometimes you need to make changes to the API base that supports your project. For example, you need to add a feature that needs an API change, a new method, or requires altering of one of the objects, or the format of one of those objects, passed to or from the API. Assuming that you are also using these objects in your public API, the public objects will also change any time you do this, which is undesirable as your clients may rely on the API objects remaining identical for their parsing code to work. (cough C++ WSDL clients...) So one potential solution is to version the API. But when we say "version" the API, it sounds like this also must mean to version the API objects as well as well as providing duplicate method calls for each changed method signature. So I would then have a plain old clr object for each version of my api, which again seems undesirable. And even if I do this, I surely won't be building each object from scratch as that would end up with vast amounts of duplicated code. Rather, the API is likely to extend the private objects we are using for our base API, but then we run into the same problem because added properties would also be available in the public API when they are not supposed to be. So what is some sanity that is usually applied to this situation? I know many public services such as Git for Windows maintains a versioned API, but I'm having trouble imagining an architecture that supports this without vast amounts of duplicate code covering the various versioned methods and input/output objects. I'm aware that processes such as semantic versioning attempt to put some sanity on when public API breaks should occur. The problem is more that it seems like many or most changes require breaking the public API if the objects aren't more separated, but I don't see a good way to do that without duplicating code.

• Backing up mail accounts without full access to mailserver

  - by Agos

  Hi everybody. I'm in the process of migrating some stuff from a (crappy) hosting. Files were easy with SSH access, but mail is giving me some thoughts. This is the situation: qmail server, no ssh access I own postmaster account accounts are accessible via web interface or POP3 I'm interested in transferring emails, but if whole accounts can be transferred it'd be better. Being POP3 I'm fairly confident every message has been downloaded, but of course I'd like to download the whole thing to be safer. Right now I have this in mind: Enter in web admin Change each account's password (it's only a dozen or so accounts so still feasible) Send new password to user telling him please not to change it getmail or something like that put on new IMAP server in some way (which I still haven't planned) But I feel there should be a better way to do this. Is there? Thanks in advance!

• Selling an open source project: some issues

  - by Sander

  I am the creator / main developer of a small sized open source (PHP) project (GPL3). Currently there is a development team of 3 people (me included). This team has been quite active for some time, but since almost 2 years not much has happened. I myself have decided I want to stop working on the project, but I can't just leave the project because I care about it and I know if I abandon it, it will just be a matter of time before the project completely dies. At this moment, there are still some users and the project is only slightly out-of-date. So I'm thinking about selling the whole project. Of course I'd need to get consent of the other developers, but for now I'm assuming that's not a big problem. So at this moment I have 2 questions: 1) If the project would be sold to a commercial party, would it be possible for them to convert the project to closed source? I would prefer to sell the project to a company/organization that would continue the development under an open source license. 2) Does anyone have any tips to find interested parties? I don't know if I just want to put up a "For Sale" sign on the website of the project. Maybe someone has experience with a comparable situation. Ok guys, thanks in advance!

• What useful things can one add to one's .bashrc?

  - by gyaresu

  Is there anything that you can't live without and will make my life SO much easier? Here are some that I use ('diskspace' & 'folders' are particularly handy). # some more ls aliases alias ll='ls -alh' alias la='ls -A' alias l='ls -CFlh' alias woo='fortune' alias lsd="ls -alF | grep /$" # This is GOLD for finding out what is taking so much space on your drives! alias diskspace="du -S | sort -n -r |more" # Command line mplayer movie watching for the win. alias mp="mplayer -fs" # Show me the size (sorted) of only the folders in this directory alias folders="find . -maxdepth 1 -type d -print | xargs du -sk | sort -rn" # This will keep you sane when you're about to smash the keyboard again. alias frak="fortune" # This is where you put your hand rolled scripts (remember to chmod them) PATH="$HOME/bin:$PATH"

• Commands don't have permission when using absplute path

  - by Markos

  I have folders set up this way: /srv/samba/video getfacl /srv/samba/video # file: srv/samba/video # owner: root # group: nogroup user::rwx group::--- group:sambaclients:rwx group:deluge:rwx mask::rwx other::--- default:user::rwx default:group::--- default:group:sambaclients:rwx default:group:deluge:rwx default:mask::rwx default:other::--- That means, user deluge has rwx to folder /srv/samba/video. However, when running command as user deluge, I am getting weird permission errors. When in folder /srv/samba/video: sudo -u deluge mkdir foo works flawlessly. But when using absolute path: sudo -u deluge mkdir /srv/samba/video/foo I am getting permission denied. When running sudo -u deluge id, I get output uid=113(deluge) gid=124(deluge) skupiny=124(deluge) which shows that user deluge is indeed in group deluge. Also, the behavior was the same when I gave the permissions also to user deluge not just group deluge. When executing as non-system user, it does work. The reason that I want to use absolute paths is that I am using automatically triggered post-download script which extracts some files into the folder. I have spent way too many hours to solve this problem myself. mkdir isn't the only command that fails, touch is doing the same thing, so I suspect that it's not mkdir's fault. If you need more info, I will try to put it in here, just ask. Thanx in advance.

• Macbook Pro 15-inch replacement battery.

  - by ricbax

  So I've finally got to the 300+ cycles with my MBP 2008's original battery. Apple is pretty much "on the money" too! I am at 79% Health and getting the Condition: Replace Soon warning. So I went out to the closest Apple Store and bought a replacement. I would like to get the same lifespan out of my replacement if possible. My question is: The battery comes with a 2 dot (green) charge on the indicator, should I put the battery in and let it run down and do a full recharge OR begin charging it immediately and then let it run all the way to empty and recharge?
