• My Windows 7 computer won't boot up and a BSOD keeps coming up; how do I solve it?

  - by opj

  Whenever I boot my Windows 7 computer, I get a blue screen of death with the following details: A problem has been detected and windows has been shut down to prevent damage to your computer. If this is the first time you've seen this stop error screen, restart you computer. If this screen appears again, follow these steps: Check for viruses on your computer. Remove any newly installed hard drives or hard drive controllers. Check your hard drive to make sure it is properly configured and terminated. Run CHKDSK /F to check for hard drive corruption, and then restart your computer. Technical Information: * STOP: 0x0000007B (0xFFFFF880009A98E8,0xFFFFFFFFC000000D,0x0000000000000000,0x0000000000000000) What does this mean, and how can I fix it so I can boot my machine once again?

• Please define: "Maximum Memory Supported - 10GB, Service Upgradable Only"

  - by Droogans

  I am assuming this means that the RAM modules can only be inserted/removed from some place very inconvenient? Maybe under the keyboard? Or does this mean something more strict, as in the only way to get an upgraded module in the laptop is via some special toolset, or verified through the hardware to allow the system to recognize the new memory? I ask because I'd want to know if I need to buy my own additional RAM, since I can't seem to find a way to get to 8GB. A Google search result turned up very little other than hits for shopping. Here is the laptop in question: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4817549&sku=T78-144301

• Can expire_logs_days be less than 1 day in MySQL?

  - by Scott

  So... yesterday I received an "after the fact email" about a campaign that has started for one of the services that I run. Now the DB server is getting hammered, hard, to the tune of about 300mb/min in binary logging for the replicate. As you could imagine, this is chewing up space at a fairly tremendous rate. My normal 7 day expiry of binary logs just isn't cutting it. I've resorted to truncating logs to just the last for 4 hours with(I'm verifying that replication is up to date with mk-heartbeat): PURGE MASTER LOGS BEFORE DATE_SUB( NOW(), INTERVAL 4 HOUR); I'm just running that from cron every few hours to weather the storm, but it made me question the minimum value for expire_logs_days. I haven't come across a value that is less than 1, but that doesn't mean that it isn't possible. http://dev.mysql.com/doc/refman/5.0/en/server-system-variables.html#sysvar_expire_logs_days gives the type as being numeric, but doesn't indicate if it's expecting integers.

• Remote Desktop Encryption

  - by Kumar

  My client is RDP 6.1 (On Windows XP SP3) and Server is Windows Server 2003. I have installed an SSL certificate on server for RDP. In the RDP settings (General tab), the Encryption method is set to SSL/TLS 1.0 and Encryption level is set to "Client Compatible". I have following questions In this case is it guaranteed that all communication is encrypted even when I remote login to the server? I mean pwd is encrypted Does RDP always use some kind of encryption even if there is no SSL certificate installed on the server? In this case I do not see security lock in the connection bar. When I set encryption level to "High" then I see security lock. I do believe that communication is both cases will be encrypted. Is it true? Please reply to my questions Thanks in advance Kumar

• Which TCP ports to use?

  - by rowatt

  Is there a TCP port range which I can be sure will not be used by anything else for traffic between two machines? If I am reading RFC6335 correctly, I can be sure that no other applications will use specific ports in the Dynamic/Private/Ephemeral range of 49152-65535. However, if I understand correctly, it also states (section 8.1.2) that an application shouldn't assume that any given port in that range is available at any given time, which would mean I can't be 100% sure that it will be unused all the time. Specifically, I want to assign specific SSH traffic to a different port for the security benefit and so I can classify it differently for QoS purposes, and not have to worry about changing the port in the future.

• Lan DNS not working after reinstall of Ubuntu 13.10

  - by DrorCohen

  I upgrade my Ubuntu desktop to 13.10. When I say upgrade I mean installed on a new partition from scratch (old partition is available if To the problem: I'm trying to ping a host (Drobo-FS server) by it's host name. I get "Unknown Host". However pinging from another computer on the same lan - works fine (a laptop with 12.04 lts). for that matter every ping from the 13.10 to the local lan by hostname fails, ping with ip works. I don't have a local DNS server but somehow all the other computers in the network find each other by host name - only this new one fails... help appreciated...

• How to read iptables -L output?

  - by skrebbel

  I'm rather new to iptables, and I'm trying to understand its output. I tried to RTFM, but to no avail when it comes to little details like these. When iptables -vnL gives me a line such as: Chain INPUT (policy DROP 2199 packets, 304K bytes) I understand the first part: on incoming data, if the list below this line does not provide any exceptions, then the default policy is to DROP incoming packets. But what does the 2199 packets, 304K bytes part mean? Is that all the packets that were dropped? Is there any way to find out which packets that were, and where they came from? Thanks!

• Do I need more RAM for programming if I switch to a 64 Bit OS?

  - by Buttercup

  Hi, Given that today (for performance reasons?) variables are usually aligned to the "bit-width" (I wanted to use "word-width" here, but on x86 a "word" is still 16 bits right?) of the processor, would switching from a 32 bit OS to its 64 bit version double the RAM usage? Would this then in turn mean that to do the same work a 32 bit OS can do with 4 GB RAM (well, the 3.x GB actually...) with a 64 bit OS I would need 8 GB of RAM for programming? Please note that I'm only talking about everyday x86 computers here.

• Export policy configuration from eTrust ITM 8.1

  - by grub

  Hi everyone. Currently we are using the Enterprise AV Solution eTrust ITM 8.1. The licenses are running out in october and we are going to replace eTrust with another AV solution. The eTrust Server is running on Windows Server 2003 SP2 with an MS SQL 2000 Standard Edition. The problem is that we've got many different policy - sets which we have to redefine in the new AV solution. Is there any way with eTrust ITM 8.1 to export the different policies as csv, pdf ... whatever? I really dont want to do that manually (that would mean one print screen after the other ;-) ) Thank you very much. grub

• Autosaving on emacs or xemacs files (preferably on loss of focus)

  - by Spencer

  Ideally I want to replicate with emacs functionality from TextMate, whereby on loss of focus i.e. I click away from the buffer, my file saves. If this isn't possible, I want to customize emacs so that it will autosave the file for every character I write. When I say this I don't mean I want to autosave to the ~ backup files. I want to save the file I am currently working on. I am working on a Fedora VM. Note I am not looking for a backup or autosave. I want the file I am actually in to save, so that if I loaded the html file I am editing in a web browser it would reflect my new changes without me having to explicitly change it.

• IIS configuration to publish files

  - by Andy.l

  I have a web service that will save a file that will be published externally through IIS. The idea was to use Webdav to save the file, but that would mean that the file could be altered externally as well. The idea is to have 2 website on the IIS server that I publish the file from. One site http://internalpublish.local/vfolder where vfolder points to a file share where the file would be saved through webdav. The other site would be http://externalpublish.com/vfolder where vfolder points to the same physical folder as on the internal site, but webdav is NOT enabled on this site. Would this cause any issues? Any feedback would be gratefully appreciated. /Andy.l

• Amazon and bandwidth limits

  - by Dave

  This question may sound weird to some of you but I have never really used cloud and above all I'm still beginner in the web development and would be really thankful if someone could answer few of my question though they may sound weird So I would like to deploy simple website to Amazon, however, I'm concerned about bandwidth as they charge 0.12GB and I'm not able to set budget limit. My problem is that I wouldn't like to pay for 1000GB of bandwidth if someone for some reason decides to download one file constantly So could some of you, who have experience with amazon, tell what happens if my app is able to handle (say 50 req/sec 30kb/page) does that mean that in the worst case I would have to pay req * sec * min * hours * days * page size 50 * 60 * 60 * 24 * 30 * 30kb = 3888GB

• Why does Outlook 2010 give the message "Creating a new item from the selected items could take some time...are you sure you create a new item...?

  - by Matt

  I'm using Outlook 2010 with Exchange 2007. I am moving emails from my Deleted Items folder to a user-created folder. When I move a "low" number of messages, say a few hundred or less, the operation completes successfully. When I move a "large" number of messages (in this example it's over 800) I get the message shown in the screenshot below. If I click Yes, a new email is generated and has links to all the emails I selected in the Attachment field. When I cancel that email, not only have the messages not moved but they appear to be deleted entirely. What does the message mean and why does it get presented? Why does clicking Yes do the behavior I described above?

• Data CD for audiobooks?

  - by Marco7757

  I'm trying to burn my .mb4-audiobook files to a CD. I was impressed by the compression-rate (10 hours of audiobook within 150MB?!). The problem now is, that I cannot burn it as an audio CD as these allow only about 80 minutes of audio (audiobook is about +10 hours). I burned them as a data CD now. It works, but, of course, the downside of a data CD is, that not every player (e.g. car, stereo) can play data CDs. What can I do? I don't want to waste 100 CDs on such a simple problem ... is there any way to burn an audio CD? I mean, just regarding the filesize this shouldn't be a problem, shouldn't it? Why is an audio CD only able to play up to 80 minutes?

• Can a network interface be configured to have a default gateway for UDP packets?

  - by Vaibhav

  It is quite possible that my question may not make a lot of sense. I apologize, but I am not a networking guy, and that's my excuse. To elaborate, WikiPedia defines "Default Gateway" as a node on a "TCP/IP" network. And the way it works is that if a network interface is sending a packet to an IP address not present on its subnet, it sends it out to the default gateway (which then knows what to do with that packet). Is this true if a UDP packet (datagram) is involved? I mean, if my network interface is sending a UDP packet to an IP address that is not present on its subnet, would it automatically send it to the Default Gateway as well?

• View Security Server and Direct Connection

  - by Poort443

  I have a Security Server for my connections from the Internet. This works fine, accept when I enable "Direct Connection to the desktop". I found the following statement on this: If you bypass the secure connection, the client must establish a direct RDP communication to the desktop virtual machine over RDP (port 3389). Does this mean I have to open 3389 (RDP) to the Internet if I want to use Direct Connections? If I disable Direct Connections to get my Security Server working, I have to disable it on my Connection Server. It's my understanding that this means that if I reboot my Connection Server, all the View clients get disconnected. Is there a way I can disable "Direct Connections" for the Security Server, while enabling it for access from the LAN? Tia.

• Lightest way to run Google Hangouts Chrome app on Mac

  - by jadengore

  I recently transitioned to Safari because I'm really tired of how Chrome hogs memory and drains my battery like crazy. The only thing that has been keeping the Chrome icon open is the Hangouts plugin. Basically, I am looking for the lightest way to run Hangouts on my Mac. By light, I mean the least amount of RAM usage, and preferably a way to do it without Chrome open/light version of Chrome that only opens extensions. Any suggestions? EDIT: Another thing I noticed was that Hangouts ignores your default browser if links are sent to you by chat, and when clicked they open in Chrome. My question doesn't relate to this at all, but I found it interesting...

• VM connected to network but not to internet in VMware Player 6 on Windows 8.1 host

  - by user1257262

  So I am running Bitnami's MEAN stack in VMware Player 6.0.2 on Windows 8.1 and the VM connects just fine to the network: https://www.dropbox.com/s/xfdzohjuuepz52w/ifconfig.PNG However, I am having a great deal of trouble getting the VM to communicate with the internet. No matter what sort of action I take (even something as simple as apt-get update), the machine just sits there and eventually fails to connect. Here is my VM's Network Adapter configuration: https://www.dropbox.com/s/xfdzohjuuepz52w/ifconfig.PNG On my host Windows 8.1 computer, I actually have the VMware Bridge Protocol enabled but for VMware Network Adapters (VMnet1 and VMnet 8), but they are listed as having No Internet access in my Network and Sharing Center. I am not entirely sure if these adapters are relevant to connecting the VM to the internet, to be honest. This is the first time I have ever had an issue connecting a virtual machine to the internet. This problem is also happening with other VM's I am trying to run. Can someone tell me what I am doing wrong and how I can fix it?

• How to migrate Notepad++ settings?

  - by NoCatharsis

  I am trying to portabilize every program I use if possible, and Notepad++ is on the list. The only problem is that I've had a native installation until now so that I'm not totally sure which settings files need to be moved to the portable directory. Surely there's a function tucked away somewhere in NPP exactly for this purpose, or some plugin out there? I mean the developers have literally thought of everything else, yet this is the one thing I cannot find specifically anywhere in the NPP wiki or otherwise, and I don't want to miss an important file. Here is the closest I've gotten: Notepad++'s configuration files and Where are all the files? Should I just copy every configuration file listed on the first link?
