  • windows 8 on macbook locks after 2 mins despite high performance settings

    - by Mark
    I am running my Macbook Prop as a Windows 8 machine using bootcamp and for some reason, when I leave the keyboard/mouse alone for 2 mins it locks the PC (i.e. goes to the lock screen). I have (of course) checked the power settings and I can assure you that it is not set to these settings. I did notice that when I added my work's Mail Account the computer asked me to accept some group policy settings, which I did, so I suspect that this is a group policy setting, but I cannot find it. Can someone help? P.S. I have searched these forums first, and this is different to the PC going to sleep once locked, this is locking while logged in after 2 mins. Thanks.

  • Advice for an EC2 Architecture and Deployment Strategy

    - by Mark
    My company is currently migrating several websites and PHP web applications (standard LAMP stack) from three in-house servers to Amazon EC2. Because we had only three servers, we clustered several low-traffic websites with perhaps one high-traffic web application, and served them from the same server. The server admin has pretty much copied the previous architecture wholesale onto the EC2 instances, simply upping the instance size to account for the highest traffic client that occupies that particular instance. This architecture might be okay if it wasn't for deployment. Any time one of these sites/apps changes, it means redeploying the entire instance, along with the 30 sites/apps it hosts, instead of just updating one. How can we architect our cloud in a more modular fashion? Should each app get its own appropriately-sized instance? What is the best strategy for deployment in this type of situation?

  • Can iranians do CCNA?

    - by Mark
    I know that Iranians can not do Sun's Java certification, how about CCNA? I've heard there is no examination centers in Iran, but can I do it outside Iran?

  • Windows 7: resizing the 'Save As' window

    - by Mark Miller
    I do not know whether my question is appropriate for this forum. Apologies if it is not. I am running Windows 7 Professional with Service Pack 1 on a Dell Vostro 460 PC. I am downloading journal articles from the internet and saving them as *.pdf files. Somehow I unintentionally clicked a button that resulted in the 'Save as' window filling the entire screen of my computer, except for the toolbar at the very bottom. How can I resize the 'Save as' window so it only fills perhaps somewhere around 25% of the computer screen, or whatever the default size for that window is? I have searched the internet extensively and found one or two threads about this problem, but no specific solutions were posted there. One suggestion was to grab the bottom of the window with the mouse and scroll upward until the window was the desired size. That does not appear to be possible in my case. Another suggestion was to click on the window with the middle mouse button before attempting to resize the window, but that does not appear to help in my case either. Thank you for any help. If I should post this question in a different forum here please let me know, or kindly migrate the question to the appropriate forum. If additional information is necessary before a solution can be attempted, please let me know that as well.

  • External speakers no longer working

    - by Mark Robinson
    We have a Windows Vista laptop. On Monday we hooked it up to external speakers, as we always do, and they worked fine. On Tuesday, we did the same but then the speakers did not work. Weirdly, the laptop internal speaker does work. Nothing was changed between Monday and Tuesday. What happened and, more importantly, how can it be fixed? BTW we tested with other speakers (and cable) and that didn't help. So it seems like a laptop issue.

  • Why is the disk making my motherboard beep?

    - by Mark Ransom
    Whenever I let my PC do heavy disk accesses for a long time, the speaker on the motherboard starts making a continuous chirping sound. Thankfully it doesn't happen often, but it drives me nuts when it does. Anybody know where this sound might be coming from, or have any hints as to how to track it down? Edit: The problem appears to be with the processor, the correlation with disk access was coincidental. Thanks for all the answers.

  • In Excel how can I sum all the numbers above the current cell?

    - by Mark Meuer
    I want to have a column in Excel that consists of a header, a bunch of numbers, and then have the sum of those numbers at the bottom. I'd like the sum to adapt to the insertion of new numbers above the total. Something like this: Numbers 1 2 5 10 18 Total If I later insert 10 new numbers in the middle of the list, I want the sum to automatically include them. I know the SUM() function can sum a whole column, but if the total is also in that column then it complains about a circular reference. How can I just sum the numbers above the total?

  • Create DFS replica from a NAS drive

    - by Mark
    We have two offices, at two different locations. In one we have a NAS, with some shares. We also have a Domain Controller using Windows 2003 R2. We have setup a second Domain Controller using Windows 2003 R2 to put that in the second office. What we would also like is to replicate the NAS drive onto the second Domain Controller so in the second office they have a local copy, and that their changes are replicated back to the NAS. Is there a way to setup DFS replication to do this? Or will it only work with local folders on each Server? Update 1 Sept Base on the answer below, I think I need to add some clarification. The real issue is that the NAS which hosts the shared folder that we want to replicate is external to both servers. And we have a particular share mapped to say S: . In the replication setup it doesnt seem to accept network shares external to the server to be candidates for replication. I can understand why, I just need confirmation that DFSR will only work with block devices that are local on at least one server. Is this the case?

  • router with mixed-mode enabled - does it really cripple speeds for all?

    - by Mark C
    Hey all, If I have a router that has "mixed mode" enabled to allow b, g, and n devices, it is true that n devices will suffer in reduced bandwidth if there are any non-n devices connected? I found one article on the internet after a quick google search: http://www.wi-fiplanet.com/news/article.php/3335801 Can anyone corroborate or give their opinion on the matter? Thanks!

  • Is rsync corrupting my RAR?

    - by Mark Henderson
    We have two qnap devices - one in our datacentre and one off-site. We have hundreds of password protected RAR files stored on the qnap that contain virtual machine image snapshots, with approx 20 of them being created each day. We synchronise the two devices using rsync, and it looks like all the files are being rsynced OK - they come over and have the same file size and all the files are present and accounted for. However, when I try to open the RAR files on the remote site, I get Cannot open \\qnap01\FromDatacentre\Snapshots\DB001SQL1-20110626.rar I can open the RAR files on the local site just fine, so I assume that something is getting mangled during the rsync procedure. However, the older files (pre 2011-06-20) work just fine, it's something that's only started happening in the last week. There haven't been (as far as I know) any changes to any of the devices, setup or configuration in that time. Obviously something has changed though. Where should I start investigating?

  • How can I identify a mystery tray icon in Windows 7?

    - by Mark
    A new icon has appeared in my tray in Windows 7 recently - a black square with a white A in it: It doesn't have any tooltip or right-click context menu so I haven't been able to identify which process it belongs to. I tried using the "Find Window's Process" tool in Process Explorer but that won't identify individual tray icons. Short of killing processes until it disappears, is there a good way to identify which process this icon belongs to?

  • After deleting log files, Ubuntu server still saying there is no space

    - by Mark
    My Ubuntu server has stopped due to a lack of disk space. I deleted some log files which has grown huge very quickly. But df -h still shows I have no space left. When I run du -sh /* I can see that I should have plenty of disk space left after deleting the logs. I ran lsof +L1 and it brought up two files: /var/log/mail.log and /var/log/mail.err. These are two logs I had deleted. I restarted apache, postfix and mysql (mysql wont restart because of lack of disk space, it think) but still df -h shows no space.

  • Nginx return 444 depending on upstream response code

    - by Mark
    I have nginx setup to pass to an upstream using proxy pass. The upstream is written to return a 502 http response on certain requests, rather then returning the 502 with all the header I would like nginx to recoginse this and return 444 so nothing is returned. Is this possible? I also tried to return 444 on any 50x error but it doesn't work either. location / { return 444; } location ^~ /service/v1/ { proxy_pass http://127.0.0.1:3333; proxy_next_upstream error timeout http_502; error_page 500 502 503 504 /50x.html; } location = /50x.html { return 444; } error_page 404 /404.html; location = /404.html { return 444; }

  • How to effectively secure a dedicated server for intranet use?

    - by Mark
    I need to secure a dedicated server for intranet use, the server is managed so will have software based security, but what other security should be considered for enterprise level security? The intranet is a host for an ECM (Alfresco) managing and storing sensitive documents. As the information is sensitive we are trying to make it as secure as reasonably possible (requirement in UK law). We plan to encrypt the data on the database. It will be connected to via SSL encryption. Should we consider Hardware firewall, Private lan between the application server and database server?

  • How do I know if my disks are being hit with too much IO reads or writes or both?

    - by Mark F
    Hi All, So I know a bit about disk I/O and bottlenecks relating to this especially when relating to databases. But how do I really know what the max IO numbers will be for my disks? What metric might be available to me for working out roughly (but needs to be a good approximation) of how much capacity (if you will) have I got left available in I/O. I've seen it before where things are bubbling along nicely and then all of a sudden, everything screams to a halt, and it ends up being an IO bound problem. Is there a better way to predict when IO is reaching its limits? This article was interesting but not giving the answer I desire. "http://serverfault.com/questions/61510/linux-how-can-i-see-whats-waiting-for-disk-io". So is my best bet surrounding just looking at 'CPU IO WAIT'? There must be a more reactive method for this? Best, M

    Dear ladies and sirs. My C: drive is full. I wish to move the builds folder from the job to another location. I can cheat with the help of the JUNCTION utility to redirect the original builds folder, but I am interested to know if there is the Hudson way to do it right. Thanks.

  • Multiple computers in SBS domain that need a Remote Desktop Connection with a sub domain

    - by Mark
    Hi all, I've been searching the internet for a while for this answer. I have a bunch of computers that are part of a small business server domain and would like to be able to connect to each one individually with remote desktop connection using a subdomain, like: computer1.mydomain.org computer2.mydomain.org etc... I can currently connect to the server easily using an A record with the subdomain pointing to the static IP address with home.mydomain.org, so computer1.home.mydomain.org would also be cool. Thanks!

  • Hosting solution for sensitive client data

    - by Mark
    Hello, We are developing a web application that will deal with highly sensitive (financial) data of clients (audience is medium to large sized businesses). Clients will be under scrutiny from regulators & auditors and, as such, we will be too. More importantly to give clients a level of comfort our application and related hosting arrangement should instill a lot of confidence with them. We are looking into using a cloud based service like Linode, Amazon EC2, etc. To allow for maximum flexibility We are keen on putting everything on virtual servers and avoiding having to buy our own hardware. Does a cloud based service make sense for our particular scenario? If not what type of hosting should we consider? If so what should we look out for? Thanks!

  • Fill rows down quickly (column or matrix of zeros)

    - by Mark Miller
    I have an extremely basic question, but I have never found the answer by searching the internet. I simply want to create a large column of zeros with Excel. Sometimes I want to create a huge matrix of zeros (maybe 600 rows by 500 columns) and then replace a few zeros with 1's to create a model design matrix. I have always started by creating a column of, for example, 10 zeros, copying and pasting those zeroes, then copying and pasting the resulting column of 20 zeros, etc., until I had the desired number of rows. Then I would copy and paste that column of zeros one at a time over and over until I had the desired number of columns. This procedure is tedious and time-consuming and I know there must be an easier way. Do you know of any other methods?
