  • Smart Phones Shockingly Energy Efficient; Lead to Decreased Household Power Consumption

    - by Jason Fitzpatrick
    Given how often our smart phones and tablets spend plugged in and topping off their battery reserves, it’s easy to assume they’re sucking down a lot of power. Analysis shows the lilliputian but powerful devices are surprisingly efficient and may be decreasing our overall power consumption. Courtesy of energy-centric blog Outlier, we’re treated to a look at the power sipping habits of popular smart phones and mobile devices. The simple take away? They use shockingly little electricity over the course of the year–you can charge your new iPhone for a year of regular usage for under a buck. The more complex analysis? The proliferation of tiny and energy efficient devices is displacing heavier energy consumers (large televisions, desktop computers, etc.) and driving a more efficient gadget-to-consumption ratio is many households. Hit up the link below to read the full post. How Much Does It Take to Charge an iPhone [via Mashable] 7 Ways To Free Up Hard Disk Space On Windows HTG Explains: How System Restore Works in Windows HTG Explains: How Antivirus Software Works

  • strlen returns incorrect value when called in gdb

    - by alesplin
    So I'm noticing some severely incorrect behavior from calls to standard library functions inside GDB. I have the following program to illustrate: #include <stdio.h> #include <stdlib.h> #include <string.h> int main(int argc, char *argv[]) { char *s1 = "test"; char *s2 = calloc(strlen("test")+1,sizeof(char)); snprintf(s2,strlen("test")+1,"test"); printf("string constant: %lu\n", strlen(s1)); printf("allocated string: %lu\n", strlen(s2)); free(s2); return 0; } When run from the command-line, this program outputs just what you'd expect: string constant: 4 allocated string: 4 However, in GDB, I get the following, incorrect output from calls to strlen(): (gdb) p strlen(s1) $1 = -938856896 (gdb) p strlen(s2) $2 = -938856896 I'm pretty sure this is a problem with glibc shipped with Ubuntu (I'm using 10.10), but this is a serious problem for those of us who spend lots of time in GDB. Is anyone else experiencing this kind of error? What's the best way to fix it? Build glibc from source? (I'm already running a version of GDB built from source)

  • Artificial Intelligence ... how to make an object roam freely/avoid other objects, and model consciousness? [on hold]

    - by help bonafide pigeons
    Say a simple free roam battle scene in which a player runs around freely and engages in battle with other enemies/objects, as shown below: The dragon/dinosaur (or whatever that thing I drew appears to be) will, by some measure, try and avoid attacks so it is modeled to appear to have a conscious desire to avoid pain. My question is ... since this is very complex, many possible strategies for solving this, algorithms, etc., what is the basic idea behind how this would be accomplished in any sort? Like, we can assume the enemy in the picture is not just going to aimlessly hop around and avoid, but freely be modeled to behave as if it were really exploring/fighting. For the best example I can give, witness the behavior of the enemies in Final Fantasy 12 in this video: http://www.youtube.com/watch?v=mO0TkmhiQ6w How do the pros, or how would anyone attempt solve/implement this? PS: I have tried several times to give an image the "illusion" that is has a conciousness, but aside from emulating a real animal's consciousness in complete, I fall short and get choppy moving images that follow predictable patterns, error-prone movements, and the worst imaginable scenario of a battle engagement.

  • How to Edit aspx, Cshtml and other kind of files live on FTP server ?

    - by Anirudha
    Originally posted on: http://geekswithblogs.net/anirugu/archive/2013/06/27/how-to-edit-aspx-cshtml-and-other-kind-of-files.aspxMany time we just want to make a small changes on site and we don’t want to download the whole project again. In this post I will show you some good way to do it.   People who have Expression Web 4 can do it. I tried it and it’s work good with aspx file. If you have site in asp.net and use aspx engine then this is a good option. Well, Expression Web is free (previously paid software). A another good option is Komodo Edit. You can use komodo edit and few plugin to make FTP editing work for you. The problem in these 2 apps are they don’t have syntax highlight and support for CSHTML file which are introduced with MVC 3. For this I suggest you to go with webmatrix. You can use Webmatrix to edit cshtml file online. Remember that Webmatrix don’t support Compiling of MVC project. You need Visual Web developer Express at-least to compile your project. if you are in hurry try  https://c9.io/ put your FTP settings and you just got your hands ready to make changes on live site. If you have anything else in your mind share it here.

  • Kloxo - Use third party nameserver

    - by LePhleg
    Here's my case: I got my domain from a registrar. I got my VPS up from a provider who also offers free DNS hosting, on their own server (separately from my VPS, IP:111.111.111.111). So I got these third-party nameservers, lets name them: ns1.provider.com ns2.provider.com and pointed my domain registrar to them. I let it propagate for 24 hours so I believe its ok. (if I ping my domain I get the IP for these nameservers - 111.111.111.111) Afterwards I headed to my providers cPanel (the one they gave me for the DNS hosting service) and changed the default A Record IP from 111.111.111.111 to the IP associated with my VPS (IP:222.222.222.222). The last step, as I see it, is to configure my VPS via Kloxo panel and add the domain. Can someone guide me how can I achieve that? Is it just enough to create a new DNS Template and add as Primary DNS "ns1.provider.com" and Secondary DNS "ns2.provider.com"? Every tutorial I found is using Kloxo to create local nameservers on the same VPS which is something I want to avoid to save resources..

  • What is the best way to configure the number of workers in Apache?

    - by rbm
    My site receives a lot of traffic for 2 hours during the day (2000 hits per minute). The rest of the day receives less traffic(500e hits per minute). I have been experimenting with the MaxClients and MaxSpareServers values but I still get some downtime during peek hours. How can I calculate the best values for my configuration based on the amount of ram that I have ? Each process is like 36-40 M of Memory total used free shared buffers cached Mem: 3096 793 2302 0 0 0 -/+ buffers/cache: 793 2302 Swap: 0 0 0 Values that I am using now <IfModule prefork.c> StartServers 10 MinSpareServers 22 MaxSpareServers 60 ServerLimit 90 MaxClients 90 MaxRequestsPerChild 400 </IfModule>

  • Tell the linux kernel to put a file in the disk cache?

    - by Rory
    Is there any command to for a file to be read in and loaded into the linux disk cache? This is on an up-to-date debian system. I know in the general case, it's better to let the linux kernel figure this out. But I have an edge case. I have a laptop that has an NFS director mounted, and i want to play a long video file, but I don't want to have a network problem interrupt the playnig. I know that (largeish) file will be read in it's entirety later on. I know that nothing else (really) will be running while playing this video. There is enough free memory to store this file. (I know I could just copy the file into a new tmpfs filesystem, but I'm curious if there's an even shorter way to do it)

  • How to recover the data from the crashed (external) hard disk drive (NTFS)?

    - by shveerab
    The 300 GB harddisk has 2 partitions,90 GB and 200 GB! I can see the drives in windows(XP) but unable to access them, the file system is shown as RAW, 0 used space and 0 free space!..chkdsk returns the error "unable to determine volume version and date. chkddsk aborted." Is the MBR corrupt? How do I restore it? TestDisk tool isn't recognizing the partitions and says invalid entry for heads/cylinder, 15 and should be 255 and suggests to change it..Should I go ahead and change it? Please advise!

  • First-class help desk solution? [closed]

    - by Andy Gregory
    A help desk, for larger companies is a place for centralized help within an enterprise to help the users of their products and services.Therefore,to find the solution that best fits your business requirements, it is important to research, examine, and compare help desk software. As far as I know,Hesk is an free helpdesk software with some limited features while h2desk can provide the hosted solution. But for my small business,i just need a web based help desk software which can provide ticket management and knowledge base faq. We need unlimited staff support. Maybe a freeware help desk software can not meet our needs. So,we are willing to pay for effective helpdesk solution. But it should be low cost. We have gotten two choice: iKode Helpdesk Nethelpdesk Our helpdesk team are tend to iKode Helpdesk. Any other efficient first-class help desk solution to share?

  • Grub can not boot after resizing windows XP (NTFS) partition. What is to be done? [closed]

    - by cipricus
    Possible Duplicate: How to Repair Grub while dual booting ( win7 / ubuntu 11.10) I had installed Lubuntu on a PC with Windows XP and used dual boot for some time with no problems. Since I had almost abandoned Windows (kept it for printing...) I decided to resize its ntfs partition and add the free space to my Ubuntu space. Tried that with a gparted stick and a live cd but would not work due to an issue related to the ntfs partition: gparted signaled with a red exclamation point that there was a problem with that partition. I read that a checkdisk might solve it but in the end used EaseUS in Windows to shrink (resize) the ntfs partition and create a new one (ext3) from the space left. All seemed ok with that procedure: but resizing the partition and moving the data might have affected the grub file: or whatever the following message means, which I get when trying to start my pc: error: file not found grub rescue> Booting from a live cd I see, beside the shrinked windows partition and my old linux one, the newly created partition, containing a directory called lost+found that I cannot open. Can I fix the grub file and recover both my XP and Lubuntu installations?

  • VPN Authentication Credentials (Local/Remote Identifiers) For Remote Access VPN

    - by thatidiotguy
    So I am trying to set up a remote access VPN using the free ShrewSoft vpn client: https://www.shrew.net/software I want to use a PSK as the authentication mechanism combined with XAuth so that a connection requires a valid username/pass combo. Under the authentication tab this particular VPN Client however is asking for a Local Identity and a Remote Identity. The options for Local Identity Type are: Fully Qualified Domain Name User Fully Qualified Domain Name IP Address Key Identifier The options for Remote Identity are: Any Fully Qualified Domain Name User Fully Qualified Domain Name IP Address Key Identifier My current thinking is that I can use the Fully Qualifed Domain Name provided by the remote firewall for the Remote Identity, but I do not know what it wants for local identity. Just to stress: I am not trying to set up a site to site VPN. Can anybody shed any light on what I am missing here? A screenshot can be provided if that would be helpful. The current error I am getting during the connection is: IKE Responder: Proposed IKE ID mismatch

  • Update 3 for "NetBeans Platform for Beginners"

    - by Geertjan
    The latest monthly update of NetBeans Platform for Beginners was released during the last few days. Without any question at all, this book is awesome. I love how it is a 'living book' and that on a monthly basis new updates are made available. In this particular update, as before, reader comments and questions have led to changes and enhancements in the book. In addition, there's now a tighter integration between the long list of samples on GitHub and the book, since wherever a sample relates to a text in the book, the book has a handy icon, so that you know when to hop over to GitHub to get a related sample. Do you have comments or questions about the book? That's what the feedback link is for: https://leanpub.com/nbp4beginners/feedback And there's also a free sample, just in case you'd like to get a feel for the book prior to buying it: http://samples.leanpub.com/nbp4beginners-sample.pdf If you're from a company where you're all sharing a single copy of the book, it would be great if you'd go back and support this great project (and hopefully encourage future books being written) by buying additional copies, ideally one for each developer. Let's show the authors that writing books on the NetBeans Platform is a really profitable thing to do (and I'm hoping they'll write one on Maven and the NetBeans Platform, as well)!

  • La merde d'Oracle

    - by hakim
    Que comprendre chez oracle qui nous propose toujours de télécharger Solaris 10 et opensolaris? Où est la nouvelle version d'opensolaris 2010.02 ou 2010.03 promise alors que nous sommes au mois de mai? On se paye notre tête? Le temps s'est-il arrété pour Oracle en juin 2009 avec la version 2009.06 plutot expérimentale? Quand à solaris, il vaut mieux peut-être ne pas rentrer dans les détails: Les dirigants d'oracles pensent-ils qu'on peut travailler avec un système qui ne donne de drivers ni pour l'essentiel des cartes graphiques, ni pour les cartes réseaux, ... Mesieurs, nous sommes en 2010; heuresement qu'il y'a free BSD et les différents Linux pour nous permettre réellement de travailler sur nos machines et de produire au lieu de gaspiller notre temps avec vos svcs, svcsadm, ... de merde!

  • Commercial template (theme) sellers which give license to resell the template?

    - by Tony_Henrich
    I came once across a website template seller which granted rights to resell the template to the buyer but forgot to bookmark it. All the commercial template vendors I know of (Template Monster, BoxedArt, Dreamtemplate..etc) don't allow this. Anyone knows of any sellers which allow this? Some of them allow you to resell the template if it's packaged for a different host software. For example, if I buy a website template, I am allowed to sell it as a WordPress or Joomla or Drupal theme. I am aware of public domain and free templates sites but I am not looking for those. I am talking about templates which are being sold.

  • Is there any way to do "mail server parking"?

    - by percyboy
    I am managing a mail server, which will be temporarily closed for three or four days due to the data center maintenance. I want to find a solution to (completely or partly) solve the lost mails during this unavailable period. Because the data volume is huge, it is very hard to migrate it to other data center. One approach I think out is to setup a temporary mail server in other data center, and when new mail received, the mail server automatically sends a return mail to tell the sender "We are temporarily closed for three or four days. Please send the mail later or contact in other means." I am wondering is this approach possible with existed mail server ? Or something better available ? (free solution is preferred for it is only for temporary)

  • php returns junk characters at end of everything

    - by blindJesse
    php appears to be adding junk characters to the end of everything it returns on a friend's site. I'm not an admin on the server but I'd like to give an informed complaint to get this fixed. The site is http://daytoncodebreakers.org. You can see some junk at the end of every page on the site (what appear to be question marks with something else in the middle). I originally thought this was a wordpress issue, but check out http://daytoncodebreakers.org/whereisini.php (which is just a call to phpinfo), and http://daytoncodebreakers.org/hello.php (which is just 'Hello World'). I'm not sure if this is the most appropriate site, but I think this is a server config issue, so I'm posting it here (rather than stackoverflow or superuser). Feel free to move it if want.

  • Customer Reviews on Company Listings [closed]

    - by GSTAR
    I'm not sure if this is the right place but I am after some general advice on a feature I am looking to implement on my website. The website I have is a Wedding Directory. Here, companies can advertise in the form of a directory listing. This listing contains the company details - such as what they do and how you can contact them. There are three packages available - Basic package is free and Silver and Gold packages are charged for. Now in order to further enhance the directory, I want to enable customer reviews for each listing. This is basically whereby customers who have used a particular company's service can write a review (and rate out of 5) of their experience. The dilemma I face is that if customers are to be paying for their listings then surely they will expect to not have content on their listing that would tarnish their reputation (i.e. negative reviews). But at the same time I want to be impartial and help my site visitors to make informed choices on which companies to book when arranging their weddings. Of course I will exercise my ability to remove offensive or fake reviews but I do not want to be removing reviews just to satisfy my clients. Suppose a client pays me a premium fee to have their listing on my front page and at the top of the listings. Now suppose that client gets lost of negative reviews - the fact that they have increased visibility means that they will also get increased bad publicity. This in turn means they won't renew their package and will most likely request the listing to be taken down. So, how can I get the right balance here and keep everyone happy?

  • Installing ubuntu server as linux distro on dell server - what drivers will be missed

    - by Cookie
    Dell (via USC) unpacks specific drivers for both RedHat and Suse to use after installation on its servers. As Ubuntu server isn't officially supported, this clearly isn't happening for Ubuntu. Is Ubuntu server then running with native drivers? In that case, which drivers are native with Ubuntu, and aren't (e.g. are Dell replaced) with RedHat/Suse? Are dell optimized drivers available for Ubuntu somewhere? Can the ones for RedHat or Suse be used with Ubuntu? Are there disadvantages of this lack of fine-tuned drivers, and if yes, what are they? Would they make the switch (and extra costs, as both RedHat and Suse Enterprise aren't cheap) away from the free Ubuntu server worthwhile? Dell recommends Canonical's commercial support for Ubuntu server on its machines, is this recommendable? Do they offer fine-tuned Dell drivers to replace native drivers?

  • "The requested operation could not be completed due to a file system limitation" 3202

    I backup SQL Server database and it fails BACKUP DATABASE dd TO DISK = '\backupServer\backups\dd.bak' WITH COMPRESSION, CHECKSUM, NOFORMAT, INIT , BlockSize = 65536 , BufferCount = 2200 , MaxTransferSize = 4194304 The backup size is 3TB and I have 6TB free space on bacup server. I am using backup parameters per SQLCAT whitepaper. Everything works ok when I backup to local HDD and it always fails when I backup to network share. After about 6 hours. Can't find why. Thank you. Yes. The backup over the network is fastest and saves me 3Tb of local disk space :) Thanks for pointing to the memory issue. I left 4Gb to OS and it worked!

  • Web Content Filtering for Windows Clients

    - by djoyce
    I'm working with a small business to solve a bunch of problems. One is their Windows 7 POS registers need to have web access restricted to only three remote support sites, but the back office machine needs an unfiltered connection. I'd like something I can install and configure on the few registers to block all but those few sites. In a perfect world this would restrict the normal register user, but the admin user would not be filtered. Free is best, if it works, but a small fee would be alright too. Microsoft's Family Safety filter is close, but requires a Windows Live account, which isn't ideal, but may be alright. Anyone use this in a small business environment? I'd prefer something easily managed at the local machines. K9 Web Protection is interesting and I'm going to look into it more. Are there other options? Seems like someone would have made something simple like this as an open source project, but maybe not.

  • Feedback on meeting of the MSCC - 20.07.2013

    Impression of our meetup on 20.07.2013 Low quantity but high quality! Meetup summary: Quick introduction to ?MSCC? and interesting topics in general, especially for freshman from/at university. It also seems that the open concept of OUYA (Android-based gaming console) got some attention and hopefully new fans. More info is available online: http://www.ouya.tv/ Design contest The design contest is still going on... There's currently only one submission. Come on, you web & graphic designers in Mauritius - SHOW YOUR WORKAny draft will be published over here: MSCC Design Contest - https://www.facebook.com/media/set/?set=a.200036533488751.1073741829.181737551985316&type=3 Goodies give-away And the first 2 one-month subscriptions for Pluralsight have been well received by attendees, too. Unfortunately, we didn't have any free WiFi at Talking Drums - so, we might have to consider another location for the next meetup. Change of schedule As we spoke about the advantages of gathering during the weekend, we worked out a schedule that could be applied to future meetups of the MSCC. I'm going to address this tomorrow during our regular meetings on Wednesday to see about the response of other members, too.

  • Fun projects to do with an old 17" LCD Monitor

    - by Adam Haile
    I've got an old 17" LCD that I've had for nearly 9 years now but still works pretty well. It's been my secondary monitor for a few years, but I just got a new 24" monitor, so my current main LCD (19") will become the new secondary screen. Any good suggestions of interesting (and preferably cheap/free) hacks, etc. I could do with this old monitor? I don't want to just throw it out. For example, is there an easy way to turn it into a touch screen or something? I'm open to suggestions

  • Garage Sale Code &ndash; Everything must go!

    - by mbcrump
    Garage Sale Code     The term “Garage Sale Code” came from a post by Scott Hanselman. He defines Garage Sale Code as: Complete – It’s a whole library or application. Concise – It does one discrete thing. Clear – It’ll work when you get it. Cheap – It’s free or < 25 cents. (Quite Possibly) Crap – As with a Garage Sale, you’ll never know until you get it home if it’s useless. With the code I’ve posted here, you’ll get all 5 of those things (with an emphasis on crap). All of the projects listed below are available on CodePlex with full source code and executables (for those that just want to run it).  I plan on keeping this page updated when I complete projects that benefit the community.  You can always find this page again by swinging by http://garagesale.michaelcrump.net or you can keep on driving and find another sale.

  • VPN server on Windows Server 2008 for a small office

    - by cmbrnt
    I'm going to refurbish the IT-infrastructure for a small organization with one single office, and I'm not sure what VPN server to use. In your opinion, would the built-in Windows Server 2008 VPN server suffice or are there any specific problems with it as opposed to, for example, OpenVPN? I'd rather run a Windows native VPN server, but if there are few (preferably free) good alternatives, I could install VMware ESXi and virtualize both Windows and an OpenVPN-server. By the way, because of a low budget this office runs a solution with only one physical server. Any advice would be great to help me grasp this field of which I'm quite a novice. Thank you!
