• Tool to create unscaled call-out from a thumbnail image?

  - by Mal Ross

  I'm creating an online tutorial for some software and need to include screenshots. In particular, I want to highlight the position and appearance of a given control in a large screen. Given that I haven't got the space to show the screen at full resolution (at least, not alongside the tutorial text), I figured I would use a kind of call-out from a thumbnail. Here's my poor first effort, made in Paint.NET: Given how long this took me to craft, I'd really like to find a tool to speed things up (and make them look a little more professional!). Preferably a free one, too - or one that has a downloadable trial. The exact style it produces isn't that important, provided it achieves the desired effect. Can anyone help me out? Thanks, Mal. P.S. I'm using Windows Vista.

• Automatic repair software

  - by ADOConnection

  Do anyone knows any kind of apps or services for "taking care of servers"? (besides managed servers) There are hundreds of ways your server or application can stop working properly. Small things are easy to miss but usually easy to fix. Log overgrouth, configuration issues, etc. Of course there are best practice checklists, but its not a human task to check configuration best practices. Im sure it can be automated: some kind of agent can monitor all system settings, say what is right and wrong and give suggestions on how to make it right. I have to admin several servers and I need some kind of overview of overall situation. As well as a tool, that will fix problems automatically. Can you people suggest something? (I know its a little bit out of rules of SF, but I think this particular question is quite specific) It would be great to have something like http://stackoverflow.com/questions/1451319/asp-net-mvc-view-engine-comparison but for automation software.

• SSH - SFTP/SCP only + additional command running in background

  - by Chris

  there are many solutions described to get ur SSH-connection forced to only run SFTP by modifying the sshd_config by adding a new group match and give that new group a Forcecommand internal-sftp Well that works great but i would love to have a little more feature. My servers automatically ban IP's which try to connect often in a short time. So when you use any SFTP-Client, which opens multiple connections to work faster it can get banned instandly by the server for a long time. The servers have a script to whitelist users by administrator. I've modified this script to whitelist the user, which runs the script. All i need to do is now get the server to execute that script, when somebody logins. On SSH it's no problem, just put it in .bashrc or something like, but the Forcecommand don't runs these scripts on login. Is there any way to run such a shellscript before or at the same time as the Forcecommand get fired?

• Removing BIOS Post Messages

  - by Steve

  I am working on a project where a standard x86 desktop system will boot and run a single program until it is shut down. I would like to remove all the bios post messages so that it looks a little more "finished" and cleaner when it starts up. I was hoping that there might by a standard implementation/terms to know about so I can avoid having to dig through every manual to see if there are options, or get some advice on a standard set of tools I should be using. I was thinking about getting a board that has an image that covers up the post messages until you press a key and trying to customize it to all black, but it's not clear if this is a good direction. I started looking for OEM motherboards but my searches were filled with standard commercial stuff, or seemed to be way to big for my toy project. What is the best way to go about removing all the bios post messages and just having a blank screen or "loading" message until OS loads?

• Man pages in Linux

  - by Ayos

  I don't seem to have all the man pages that I need. For example, my college computers (running Fedora 14) have man pages for ASCII, all the standard C libraries (stdlib.h, stdio.h) and so on and so forth. I wish to "install" these pages, after looking up on the Internet I couldn't really find anything that made sense. How can I get, say, the man-page of ASCII (I know it's not really a command or a daemon or anything like that, but typing man ASCII on the college computer gets me a page with the ASCII value table + a little more information). I don't want to keep using the Internet for looking up man pages every time I need to look up a function, function prototype or the ASCII table or something like that.

• How do I reduce RAM usage on my server?

  - by Abs

  I have recently launched a site that is very popular but I am having trouble with scalability. My site makes heavy use of FFmpeg and at peak times RAM usage hits the 2 GB point quickly and the swap file starts getting used. CPU usage starts rising too. Users complain that the site is slow. They say this because all FFmpeg instances run very slow because of the number running at the same time. Users make use of FFmpeg on my server in real time. Is there anything I can consider or do to ease down the usage of the server and RAM just shooting up? Maybe there is something better than FFmpeg (!). Is the only solution "throwing some cash" at a more powerful server? I have given little information, please ask for more, so this problem can be solved.

• How should oracle vbox look like in terms of Memory, CPU and Performance? [duplicate]

  - by Nicholas DiPiazza

  This question already has an answer here: Can you help me with my capacity planning? 2 answers I've got a need for a ton of VMs to simulate some realistic load testing scenarios. I've got a bunch of different host machines that differ in ram, cpu's, etc. What should my resource manager look like? Is there a standard way to know what the CPU, Memory and Disk Utilization should be given your CPUs + Memory available + Disks available? For example, I have a box: MemTotal: 50 Gb CPUs: 8 CPUs are pretty much 100% all day long. Memory is at about 60%. Swap not getting hit. Little bewildered by why the VMs, while doing the exact same test script, are showing different virtual memory consumption. Huh.

• DIagnosing another Windows 7 Lockup

  - by MSEoris

  Im running windows 7 on a fairly modern machine (8gb ram, amd fx-6100, gtx 560ti) and I notice that periodically my windows seems to just hang for a little while. Frequently this occurs after a cold boot and i start up five or six small to medium sized programs, but also occasionally it occurs during normal usage. Basically what occurs is the screen locks up, there is no keyboard responsiveness for a period of 30 seconds to a full minute - after a bit of patience, control is returned, but I'm interested in figuring out what is causing such lockups. I checked the event log and dont see any issues, and all i can see in task manager is a spike in cpu and memory usage right after this occurs. Any tips on how to even begin to diagnose this? Thanks.

• How can I reset windows 7 file permissions?

  - by ssb

  I looked at this post and it seemed to be close to what I want, but my case might be a little worse: How can I reset my windows 7 file permissions to a rational state? Basically a while back I (very stupidly) changed the permissions on all sorts of system folders, and eventually rendered my computer virtually unusable. I managed to hack administrator privileges back onto key folders and getting it working, but in doing so I only modified permissions a lot more away from the natural state. I'm looking at this icacls stuff, but ultimately I need to reset EVERYTHING back to what it was in The Beginning, before I messed with it, from the C: directory all the way down. Right now application data is what's giving me problems, and I can't get it to work no matter how much I fiddle with those specific permissions. I will be forever grateful for help on how to do this without having to reformat.

• Can't decide on a new distro

  - by Alex W

  I've had Ubuntu (9.10) on my netbook in the past and I really liked it. I'm currently running Fedora and feeling like I should "change it up" again. I've played around with Ubuntu 10.04 Lucid a little, and so far I'm very impressed. I've always wanted to try Arch, but I'm worried I won't have the driver support I need for all the non-standard hardware in a netbook. Does anybody have a suggestion for a new distro to try? I'm preferably looking for something feature-rich over light-weight, and something that I can have up and running with a minimum of configuration (at least partially working). Thanks!

• How can one one-handed ease working in Emacs?

  - by N.N.

  My right hand is temporarily immobilized. I would like to do some minor work in Emacs, mostly in Org-mode, but also some in AUCTeX. Is there some way to ease one-handed work in Emacs such as some mode or particular work flow? For instance I noticed pressing C-x u is easier than C-_ for undoing and that it is easier to mark text with methods involving C-Space than with combinations of S- and movement commands. I have found http://stackoverflow.com/questions/2391805/how-can-i-remain-productive-with-one-hand-completely-immobilized but that is not what I am asking for. I want to ease whatever little time spent one-handed in Emacs and this is also interesting for situations where there is no injury involved, such as when one hand is occupied. I also do realize I should avoid unnecessary strain.

• Can I move a copy of Windows 7 from one machine to another?

  - by Chopper3

  This is a pretty basic question sorry but I've looked in the 'related questions' and couldn't find an answer. When Windows 7 came out I bought a copy of Home Premium, the retail box with both 32 and 64 bit versions, to install via Boot Camp on my macbook. I've just got a retail (32 and 64 bit) copy of Windows 7 Ultimate that I'd like to install instead-of/over the Home Premium version and it struck me that I should, at least in principal be able to install the Home Premium version on my son's machine - is this the case and if so is there anything I should do first or once they're installed to let MS know I'm being a good guy about this? Sorry it's such a dim question but I'm a serverfault guy really and know very little about Windows. Thanks.

• Dual-boot more than two operating systems

  - by aldorado

  I currently run Windows 7 and Ubuntu 12.04 as a dual-boot system. I need Linux, but Ubuntu freezes at least once a day. So I want to replace it with another distribution like Debian or LMDE. On the other hand I am a little concerned that I'll have troubles working with a less user friendly operating system than Ubuntu. So would it be possible to just scale down the Windows partition and install the next Linux as a third system? Thus, with a "triple-boot system" I could keep Ubuntu until I feel familiar with the new system. Afterwards, I guess, it should be possible to replace the Ubuntu partition by expanding the new system?

• http 301 redirection issue

  - by Guilhem Soulas

  I'm a little bit lost with a redirection. I want mysite.com, www.mysite.com and www.mysite.co.uk to redirect to mysite.co.uk. In Apache, I wrote this for mysite.co.uk in order to redirect www to the root domain: RewriteEngine on RewriteCond %{HTTP_HOST} ^www RewriteRule ^/(.*) http://mysite.co.uk/$1 [L,R=301] And for mysite.com, I wrote this redirect to mysite.co.uk: ServerName www.mysite.com RewriteEngine on RewriteRule ^/(.*) http://mysite.co.uk/$1 [L,R=301] This way, I can make the redirection work properly from www.mysite.com to mysite.co.uk, but it doesn't work for mysite.com too mysite.co.uk (without the www) at the same time. Could someone tell me how to make all my redirections work in all cases?

• In Outlook 2010, can you add "Categories" to the "New Email" Ribbon?

  - by Jeff

  I couldn't figure out how to do this in Outlook 2007, and I was hoping I could do it in Outlook 2010... I want the ability to quickly apply a category when composing a new email (typically a "Waiting For..." category) for things that need a response. It is possible to apply a category by clicking the "Options" ribbon, then the little arrow under the More Options section - but why can't I get the nice big "Categories" drop-down that's available in the "Tags" section of the main Outlook window. There are about a kabillion commands in the "Customize Ribbon" dialog box for the New Mail window, but I couldn't find anything about Categories. Should I just give up?

• HP Pavilion dv6 overheating, how do I set fan speed to 100% all the time?

  - by henpenben

  So I have a HP Pavilion dv6, and it works fine. But when I play, say, Minecraft, the temperature jumps to around 60c-70c. I wouldn't be bothered by this, but I bought this computer and played Minecraft on my lap. The laptop overheated and the video card melted. (I'm not kidding) So I was wondering how I could set the fan speed on my laptop to 100% all the time so it never overheats. HP has this "HP Coolsense" thing that when I pick up the laptop and wiggle it around a little bit and pretend it's unstable, the fan cranks up to 100%. I want 100% all the time without me having to pick up the laptop every 10 minutes. Thanks, henpenben

• OOMK kills mysql and apache when there is still a lot[?] of mem

  - by Flyer

  let me first say that I'm pretty new ti *nix systems and even more to server management. Anyway, I've got a little problem. I got VPS with 1gb mem, system is debian 6. I have few sites running on it, though some load can only be caused by one of them. Recently, OOMK started to kill mysql, causing wp and phpbb giving error that it can't connect to mysql server. Error itself is not good, especially if it happens at night and site becomes unavailable until I wake up and restart mysql. I have probably bad line in my cron which can be cause of it all (again, I'm new to it) */20 * * * * sync; echo 3 > /proc/sys/vm/drop_caches Well, if you need any information, let me know, since I don't really know which information can be useful here. Also, I'd like to know if it's not too bad to have above cron task.

• how to reduce size (disk space) of windows 8?

  - by humanityANDpeace

  This questions is about what things I can do to reduce the size that Windows 8 uses. Background For example: At present and with only one programm installed (MS Access 2007) I have a about 15GB of my harddisk space used. I have little space (its a 17 GB partition on a SSD disk). I would like solutions that are like: Remove files not really needed (drivers not actually needed in the system) Help files not really needed (documentation) pagefile.sys (assuming I would have 4GB ram and no real need for swaping) hiberfil.sys (used for hibernate and sleep... I need that. though I would regain about 4GB space) At best I would like to delete mostly files that I would most likely not need. Though I have no good idea where to start there. Since my setup (hardware will not change) I would be willing to delete all the drivers that windows 8 has for hardware I do not have.... The question is about ways to reduce the space that Windows 8 uses.

• which mail server is better suited for high volume? [closed]

  - by crashintoty

  I'm planning out a project (web/mobile app) that would require a mail server that could handle hundreds of thousands connections per hour (both IMAP/POP and SMTP) and has the ability to interface with PHP (or python or whatever) to dynamically create, delete and check for mailboxes? This is not for spam stuff, I just need my app to generate random mailboxes (and static/permanent ones too) to receive mail and process it for items listed on my service. The little research I've done so far has turned up courier, dovecot, cyrus and haraka. I think the ability to scale and/or load balance (I'm new to these terms, pardon me) would also be a requirement. Any ideas?

• Resolution is Being Stupid. Help me?

  - by One Terrorist

  I'm having trouble with a new computer I bought a few days ago. I have come to the conclusion that the resolution of the screen is too small, at the moment it is 1024x768 and I think it should be 1280x960, due to a message given at the resolution tab of the control panel. It states: (!) If your resolution is below 1280x960, some items on the screen may not fit on the screen. The computer is an Asus A54H and runs 64-bit operating system with Windows 7 Home Premium. This link has a screenshot of the screen at the moment, the icons and font are too big and are a little stretched. Thank you in advance!

• Setting primary IP for VPS (out of 2 available)

  - by Flyer

  I've got a little problem. My VPS (Debian box) has 1 primary IP address, but now my hosting provider decided to assign me another one due to problems with first one. Let's say new IP is 91.222.152.20 and old one 91.221.190.170. How should I make 91.222.152.20 primary one, so that everything works on this address instead of 91.221.190.170 (like ftp, mysql etc) I tried editing /etc/newtwork/interfaces setting iface eth1 inet static address 91.222.152.20 netmask 255.255.252.0 network 91.222.152.0 broadcast 91.222.155.255 gateway 91.222.152.1 I know that network is 91.222.152.0/22 so I assume that above configuration should be right. Saved, rebooted and that ended pretty bad. Couldn't even ping box on old or new IP. Had to revert to working one. So question is. What am I doing wrong and how to do it right?

• 56.6 Modem with CallerID

  - by Fuod

  Does anyone still know anything about the 56.6 modems? I'm looking for one that is easy to access via C#/VB.Net, has Caller ID and is either low-profile or USB. Also that neat little feature that lets the modem block the call from the phone (pass-through) until it has received the CallerID info would be really nice! Obviously I could just go to Best Buy and get what they have but I have no way of knowing how friendly it would be to write code for and I don't want to make multiple trips returning/exchanging etc. I'm not going to be doing anything with voice or voice mail, just recording the number from CallerID. Thanks!

• Sync two external harddrives?

  - by acidzombie24

  A little mishap happened earlier today and i am thinking i should have a copy of my external harddrive since 10% of it is very valuable. What is the best solution to keep two external harddrive in sync? i'll probably use one as regular and maybe use the other only to copy data. The easiest way to keep it in sync is to clear one drive and copy the other but 1T of data will take a long time. Whats a good existing app that will keep them in sync? freeware preferred.

• Do control groups improve system performances?

  - by qdii

  According to this website, enabling cgroups in the kernel can boost performances by sharing resources in a better way. In particular, the conclusion states that:  Nevertheless, with a little trial and error, cgroups can help you improve the efficiency of your systems’ resource usage and avoid downtime due to overusage of a single service. Kernel seeds, however, recommend to deactivate them altogether. They say: Consider these [kernel] settings poison. They remain nothing but system slow-downs. They are all off by default [in the proposed kernel config file]. Who should I trust?

• Network flooded with seemingly empty packets

  - by Adam Particka

  Let me preface this with the fact that I'm just a web developer at my company with little networking knowledge. Earlier today there was a department that lost all of their network connections so I popped open Wireshark and observed the influx of packets to my machine. There was normal traffic (ARP requests, etc.) coming in at ~50 packets every second. Then all of a sudden the log was flooded with packets arriving ~5000 a second. It looks as though they all contain the same data, just a looped sequence. We have someone here looking at it but I thought I would ask if anyone had seen anything like this before. Here's a selection from one of the captures in Wireshark. http://www.cloudshark.org/captures/06f950725c74
