• Running out of LowMem with Ubuntu PAE Kernel and 32GB of RAM

  - by magneticMonster

  I'm running a Java data import process on a 32-bit Ubuntu 10 PAE kernel machine. After running the process for a while, the oom-killer zaps my Java process. After some Googling and digging through docs, it looks like the system is running out of LowMem. I started the process for the third time and am watching free -lm show me Low: 464 386 77 with the free value (77MB) slowly decreasing. Why am I running out of lowmem and how do I increase it? Some details: $ cat /proc/sys/vm/lowmem_reserve_ratio 256 256 32 $ free -lm total used free shared buffers cached Mem: 32086 24611 7475 0 0 24012 Low: 464 407 57 High: 31621 24204 7417 -/+ buffers/cache: 598 31487 Swap: 2047 0 2047

• How can I VPN into a domain and act as if it is local?

  - by Duall

  I've looked and looked and the internet seems to have finally failed me, there's no information on my specific issue. I have two locations, and one server (sbs 2008); I need them to act like one physical LAN. I know it's possible, I just know how to set it up, or anything about VPNs, etc. So, just to clarify a bit more: 1 Small Business Server 2008 ~30 Computers with varying systems from Windows XP to 7 2 Physical Locations I use redirected folders, but since that would consume a lot of bandwith over VPN, I have a machine over there that can be the workhorse for storage. Users need to access e-mail and shared databases from this server (or possibly some form of DFS with aforementioned workhorse) from the other building. Is there a nice tutorial (or I nice person that wants to write it) online that can explain how to set up computers from an external network to act like they were in the LAN?

• Hexagonal Tiles

  - by PATRY

  i'm doing a tactical game (X-Com / Fallout style) for fun. I've decided to use an hexagonal map, but i'm having a graphic problem. My current map display is HUD-like, with only the border of the map cells displayed, without any texture. it's simple and allow for display of different types of informations by varying the color of the border. For exemple the "danger view mode" displays the borders with a color going from green (no damage possible) to red (prob of damage 90%). Now, It's a bit hard to différenciate the kind of tile the player is on. I could put a plain color (green is grass, pale blue is water...), but this is going to limit the possibilities. Thus, i would like to display a texture on my tiles. Since the map are generated, i can not use a picture for the whole map with the HUD over. So, my question is : does any one knows how i could generate the sealess hexagonal textures (algo or plugin), or if there is a site with some hexagonal tiles ?

• Suggestions for a Self-serv advertising service

  - by Mystere Man

  I am seeking a self-serv advertising service for my websites, but I have a few restrictions that seem to make what i'm looking for hard to find. Specifically, I want to place "advertise here" links on my pages and allow end-users to purchase advertising on that site, page, and location. These ads will not be part of a national network. Supports multi-tenancy - That is, I have a number of domains using the same "web application" but with customized content per domain. When a customer wants to advertise on a given domain, then the ads will only appear on that domain and on that page of the domain (even though the page name may be the same across multiple domains). Supports fixed ad prices, not just CPC. I need monthly and quarterly pricing regardless of performance. Integrates with OpenX and other ad networks, so that if there is no self-serv on a given zone, it will use national advertising or direct advertising. Shiny Ads has much of this, but i'm looking for alternatives, as their prices are a bit crazy (20%) and can only do PayPal.

• What poor management decisions have you had to deal with?

  - by tombull89

  As a junior technician I've had to deal with (or will have to deal with) some problems in the past and only being a junior technician I don't have the confidence or respect from management staff to speak up. For instance, we're having a entirely new system. From Windows Server 2003/XP going to Windows Server 2008 R2/Windows 7/VMWare/Digital Signage and the current amount of time dedicated to the training of the IT support department currently stands at 0. They seem to think that all IT systems are the same and are going to get a bit of shock when I can't help them. I think there;s some UK legislation saying a school/business have to put money and time aside for training, but I'm not sure. What have you had to deal with?

• Trouble with external monitor under Windows 7 on MacBook Pro Boot Camp

  - by Colm

  I'm running Windows 7 32-bit on a mid-2010 15" MacBook Pro Intel Core i5 under Boot Camp. I've had trouble getting it to work with my second display and searching Google for an appropriate answer has failed me. I'm on the latest version of Boot Camp - 3.2 - and have updated the drivers for the NVIDIA GeForce GT 330M. The monitor is connected via a VGA cable, and is a Dell ST2410. The monitor is recognised by Windows, which knows it's a Dell and its resolution. The desktop should be extended onto the second monitor - however nothing is showing. It remains black, though it doesn't show a lack of signal coming through which I would have expected. Any ideas what's wrong?

• Apache .htaccess problem: No input file specified.

  - by Michal M

  Hello Everyone, Can someone help me with this. I'm feeling like I've been hitting my head against a wall for over 2 hrs now. I've got Apache 2.2.8 + PHP 5.2.6 installed on my machine and the .htacces with code below works fine, no errors. RewriteEngine on RewriteCond $1 !^(index\.php|css|gfx|js|swf|robots\.txt|favicon\.ico) RewriteRule ^(.*)$ /index.php/$1 [L] The same code on my hosting provider server gives me a 404 error code and outputs only: No input file specified. index.php IS there. I know they have Apache installed (cannot find version info anywhere) and they're running PHP v5.2.8. I'm on windows xp 64-bit, they're running some Linux and php in cgi/fastcgi mode. Can anyone suggest what could be the problem? PS. if that's important that's for CodeIgniter to work with friendly URLs.

• Has anyone had luck getting an external hard drive working with a PCMCIA USB card?

  - by Carl

  I would like to know if anyone has had any success in getting and external 2.5" IDE hard drive in an external case (w/USB cable) working when plugged into a PCMCIA USB card. My hard drive doesn't work when plugged into my HT-Link Cardbus/PCMCIA USB 2.0 2-port card (NEC / 32-bit). My MP3 player will work fine when plugged into it. I tried plugging in both of the USB cables that are one one end (Y cable), and it doesn't make a difference. I read the problem may be insufficient power.

• Software development company business plan

  - by Navi

  I apologize in advance if this is the wrong forum for this question, so please forward me to the right place. I have about 10 years professional experience as software developer. Mostly on the Java platform doing server side programs. I have picked up a bit of Linux skills on the way as well. I know HTML and Javascript, so I can make a website that would not be too ugly, but I am not going to win any prizes with it. In fact I think I am pretty terrible in the user interface department. My initial plan is to do Android development. I read a few Android books and tried making a few apps. Since it is Java based I think I got the technical side down. Lately I have been thinking about iphone and Mac development, because of the relevant app store/development programs. The trouble is I don't know Objective C. As a side question, how long would it take me to become proficient in Objective C? Considering that I am working on my own and could hire somebody to help me for a short time for low wages if necessary what are my options? What are the pro and cons of the development programs app stores of Android and Apple? Which development/app stores are out there beside the ones I mentioned? Do you think it is necessary to find funds to get me started or should I just use my savings? If you have positive/negative experiences in a similar situations can you please share them? Thanks for your help.

• How can I anonymize my browser useragent, yet still be counted as a FF/Ubuntu user?

  - by Rory

  I read about EFF's Panopticlick project to see how unique your webbrowser's headers are. I would like to anonymize that a bit. My current User Agent is Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.7) Gecko/20100106 Ubuntu/9.10 (karmic) Firefox/3.5.7 I would like to make that more anonymous, however I still wanted to be counted as a Firefox and Ubuntu user. How can I change my User Agent in Firefox? What should I change it to so that it's less unique, but will be counted as a Firefox user and a Ubuntu user on web analytics software? I know that there is no guarantee that I will be counted a Firefox/Ubuntu user, just something that 'works most of the time' would be sufficent.

• Understanding IDAT chunk of PNG file format

  - by DRapp

  From the sample image below, I have a border in yellow just for display purposes only. The actual .png file is a simple black/white image 3 pixels by 3 pixels. I was originally thinking to try as a 2x2, but that would not help trying to interpret low/hi vs hi/low drawing stream. At least this way, I would have two black, one white from the top, or one white, two black from the bottom.. So I read the chunks of data, get to the IDAT chunk, decode that (zlib) and come up with 12 bytes as follows 00 20 00 40 00 80 So, my question, how does the above get broken down into the 3x3 black and white sample... Also, it is saved in palette format and properly recognizes the bit depth of 1 and color palette of 2... color pallet[0] is RGBA all zeros. Palette1 has RGBA of 255, 255, 255, 0 I'll eventually get into the multiple other depth formats later, just wanted to start with what would expect to be the easiest. Part II. Any guidance on handling the other depth formats would help if anything special to be considered especially regarding alpha channel (which I am already looking for in the palette) that might trip me up.

• Gmail Now Supports Google Drive Integration; Share Files Up to 10GB

  - by Jason Fitzpatrick

  Gmail users can now easily send large files thanks to Google Drive’s increased integration with Gmail–blow through the 25MB in-email attachment limit and share files up to 10GB. From the official Gmail announcement: Have you ever tried to attach a file to an email only to find out it’s too large to send? Now with Drive, you can insert filesup to 10GB – 400 times larger than what you can send as a traditional attachment. Also, because you’re sending a file stored in the cloud, all your recipients will have access to the same, most-up-to-date version.  Like a smart assistant, Gmail will also double-check that your recipients all have access to any files you’re sending. This works like Gmail’s forgotten attachment detector: whenever you send a file from Drive that isn’t shared with everyone, you’ll be prompted with the option to change the file’s sharing settings without leaving your email. It’ll even work with Drive links pasted directly into emails.  The new Gmail/Drive integration is rolling out in waves to users over the next few days and is accessible via the new Gmail compose window.

• Force a browser to load the 'https' edition of a website, not the 'http'?

  - by warren

  This is similar to this previous question, but I believe it's a bit different*. Sites like GMail support a preference that pushes all traffic through the SSL edition of the site rather than the plain-text protocol. For sites that don't offer such preferences (or ones that may, but I have been unable to find, like facebook), is there a way using only the browser (perhaps with a plugin or addon) to always try SSL first, and fall-back to plain-text iff SSL fails? Is that solution available on Windows, Mac OS X, and Linux? Just one? * The previous question was looking for external applications that would accomplish this goal.

• Windows Media Center Missing?

  - by Eric

  I'm running Windows Vista SP2 64-bit, but it was SP1 when I bought the laptop. It came with Windows Media Center, but I originally found no use for it, so I deleted the shortcut. Now I DO want to use it, and I can't find it anywhere. However, when I insert a DVD, the option to play it with Windows Media Center will appear, and it will launch Windows Media Center, so I must still have it on my system somewhere. My question is, where? Is there an easy way to just run the program using the Run window?

• Upgrading to x64 results in HTTP 500

  - by Dour High Arch

  I upgraded my development machine to 64-bit Win7, and now when I try to connect to a local ASP.Net project I get: HTTP Error 500 ... Calling LoadLibraryEx on ISAPI filter "C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_filter.dll" failed There are several puzzling things about this; the ASP.Net project was a .Net 2.0 ASMX so it was using C:\Windows\Microsoft.NET\Framework\v2.0.50727. If it updated to x64 without asking me, should it not use C:\Windows\Microsoft.NET\Framework64\v2.0.50727\? Where is C:\Windows\Microsoft.NET\Framework\v4.0.30319\ coming from? I opened IIS Manager and the selected .Net Framework version for my machine is 2.0.50727. Framework version for my default application pool is the same. I am developing in VS2008, which does not even have an option for targeting .Net 4.0.

• Is NVIDIA GeForce GTX 480 Video Card Compatbile with a Mac Pro Running Windows 7 Pro 64?

  - by aquat33nfan

  I have a Mac Pro (early 2008) and I'm running Windows 7 Pro (64 bit) natively (i.e., with just Windows installed and no OSX or boot camp) on it. If I buy an NVIDIA GeForce GTX 480 video card, will it work or do I have to buy a card that is Mac-specific (e.g., GeForce GTX 285 'for Mac')? Also, more generally, will Windows video cards work on Intel Macs running Windows (in case I pick a cheaper card)? I can't tell if it matters that a Mac does not have a bios. I searched other boards and I gathered that video cards would work fine because Windows has the proper drivers for them and OSX doesn't and not having the BIOS doesn't make a difference. I found one thread on here that seemed to indicate that as well, but I wanted to make sure. Thanks.

• ZSH - output whole history?

  - by GorillaSandwich

  I recently switched from bash to zsh. In bash one way (besides recursive search) that I used to find previously-run commands was history | grep whatever, where whatever is the bit of command I remember. In zsh, this isn't working. history returns only a few items, even though my .zsh_history file contains many entries, which I have configured it to do. How can I output my whole history, suitable for searching with grep? (Note: I started out using ryanb's dotfiles, so perhaps it's a problem with his default settings?)

• Strange Exchange 2010 Mailbox issues

  - by jmreicha

  A little bit of information on my environment. I have 2 Exchange 2010 mailbox servers setup in a DAG, connected to a VNX SAN via fiber for the mailbox database disks. One of the servers seems to be working fine as it isn't throwing any similar errors but the other has been receiving strange errors in Event Viewer. I haven't been able to find a pattern to when these happen and I'm not really sure what I should be looking at to troubleshoot this. At this point I am wondering if the issue resides on the SAN or if this is because of an improper shutdown or something else on the Exchange side of things? Here are a few of the errors if that helps:

• Windows 7 - You don't have permissions to save in this folder

  - by James

  Huh? I'm getting this message - "You don't have permissions to save in this folder" - even though I am the only user on this machine, and administrator. How can I set permissions for myself to do everything, everywhere (including saving deleting etc)? Thanks. Edit: Sorry, forgot to say which folder it was. It is a folder in Program Files, where I save my PHP files for local testing. Sorry if Im a bit daft with all this, but I've upgraded straight from XP to 7, and having never used vista, I'm used to being allowed to have full control.

• What free OS should I use on my VPS?

  - by earlz

  Hello, I looked a bit but didn't see any duplicate of this so my question is which free(open source) OS do you use on servers and why do you use that OS? Background I have a VPS at Linode. There is a broad range of options for which OS I can put on it including both 32 and 64bit OSs. I just use it to run my small blog and for hosting random files. It's very low traffic. I have been using 64bit Arch Linux on my VPS and though I love the OS for general usage, for a server the constant breakage is troublesome. So I'm considering trying something new and am looking for suggestions.

• Start a new project. Where is the inspiration ?

  - by Kakawait

  The question may seem strange at first glance ... And I may be alone in this situation. But currently I want to improve my skill through learning new framework. however, do a simple "HelloWorld" application does not satisfy me. I think a practical project is required to apprehend the basics of a framework. I know there is many scholar-like project like design a library manager or CMS. But I have recently planned to learn ~3 differents frameworks and I can't find any motivations through "unexciting" project. In the end I have not started any framework ... I'm aware of I do not develop the project of the year ... I'm just looking for something a bit exciting. I do not expect any project subject, anyway stimulation provided by a project is something subjective. But I want to know your inspiration ! (or method to learn framework ^^) I'm talking about web-dev framework but I'm open to any kind information ! Kind regards.

• unable to properly execute binaries from PHP

  - by Lowgain

  I was building an app on a SUSE box, and had a binary called create_group for instance, which had a suid bit and allowed my PHP app to call exec('create group grpname'); and create a new group (there are others for users, etc). The binary was a small c script that calls setuid(0) and then runs the user creation stuff. This worked perfectly on the SUSE box I recently moved my project to Ubuntu and everything works fine except these binaries. I can run them from the shell and they work okay, but when I get the PHP app to run them it just does nothing. Is there anything Ubuntu would be doing differently that I'm missing?

• People != Resources

  - by eddraper

  Ken Tabor’s blog post “They Are not Resources – We Are People” struck a chord with me.  I distinctly remember hearing the term “resources” within the context of “people” for the first time back in the late 90’s.  I was in a meeting at Compaq and a manager had been faced with some new scope for an IT project he was managing.  His response was that he needed more “resources” in order to get the job done.  As I knew the timeline for the project was fixed and the process for acquiring additional funding would almost certainly extend beyond his expected delivery date, I wondered what he meant.  After the meeting, I asked him what he meant… his response was that he needed some more “bodies” to get the job done.  For a minute, my mind whirred… why is it so difficult to simply say “people?”  This particular manager was neither a bad person nor a bad manager… quite the contrary.  I respected him quite a bit and still do.  Over time, I began to notice that he was what could be termed an “early adopter” of many “Business speak” terms – such as “sooner rather than later,” “thrown a curve,” “boil the ocean” etcetera.  Over time, I’ve discovered that much of this lexicon can actually be useful, though cliché and overused.  For example, “Boil the ocean” does serve a useful purpose in distilling a lot of verbiage and meaning into three simple words that paint a clear mental picture.  The term “resources” would serve a similar purpose if it were applied to the concept of time, funding, or people.  The problem is that this never happened.  “Resources”, “bodies”, “ICs” (individual contributors)… this is what “people” have become in the IT business world.  Why?  We’re talking about simple word choices here.  Why have human beings been deliberately dehumanized and abstracted in this manner? What useful purpose does it serve other than to demean and denigrate?

• HP dv9000 Vista laptop won't boot from CD/DVD drive

  - by ScottEdwards2000

  My HP dv9000 Vista laptop recently got the BSOD with error 0x0000c1f5. The only way to fix this error is to be able to boot from CD/DVD and use some repair software I have. The problem is that the laptop REFUSES to boot from any CD/DVD I try. I've changed the boot order so the CD/DVD is first, and I can hear the drive spin up a bit upon power-up, but after a second, it spins down and then the laptop tries to boot from hard drive. Any ideas? (I've tried lots of CDs so it's not the media itself) Thanks much!
