• Will SSD degrade when running VMWare Workstation from SSD?

  - by Andrey Botalov

  My main OS (Windows 7 or 8) is runned from SSD. I'd want to run Mac OS X 10.7 or 10.8 using VMWare workstation. I've heard that VMWare doesn't support TRIM and other things to optimize SSD usage. So SSD will quickly degrade if VM will be runned from SSD. Will it be better to put guest OS's files (.vmdk and the rest) to external HDD (connected through USB 2 or 3) instead of SSD? What advantages and disadvantages it will give? What if VM will be put to internal HDD? At what drive type performance of VM will be better?

• How do you pick what server setup you need?

  - by ed209

  I recently started receiving pubsub data feed from etsy. It averages around 250 notifications per minute. But obviously, when the USA wakes up that spikes quite heavily. I want to be able to deal with those spikes (about 3 per day) but the rest of day is fine. What's the best method of getting the right server configuration. My current approach is to keep upgrading until the server stops dying... next leap is: Processor: AMD Phenom II X6-1055T HEXA Core RAM: 4GB DDR2 SDRAM HD1: SATA Drive (7,200 rpm) (+500 GB 7200 RPM SATA hard drive) HD2: SATA Backup Drive (+500 GB SATA (7,200 rpm)) OS: Linux OS (+CentOS 5 64-bit) Bandwidth: 6000GB Monthly Transfer (3000 in + 3000 out) (+100M uplink port) What's the best approach to working out what sort of server setup you need?

• How do I change the canvas size of a PNG with ImageMagick (GraphicsMagick)? (How to pad with transparency?)

  - by Pistos

  Alternatively: How do I take a non-square PNG and "fill out" the "rest" of the image with transparency so that the resulting square image has the original image centered in the square? ULTIMATELY, what I want is to take any image of any GM-supported format of any size, and create a scaled-down PNG (say, 40 pixels maximum for either dimension), with aspect ratio maintained, transparency-padded for non-square original images, AND with an already-prepared 40x40 PNG transparency mask applied. I already know how to scale down and keep aspect ratio; I already have the command for applying my composite. My only missing piece is square-alizing non-square images (padding with transparency). Single command preferred; multi-command chain acceptable. (edit) Extra info: Here's the composite command I'm using: gm composite -compose copyopacity mask.png source-and-target.png source-and-target.png where mask.png has white pixels for what I want to keep of source-and-target.png and transparent pixels for what I want to remove (and become transparent) of source-and-target.png.

• Why are the Volume and other indicators missing on my eMachines eM355?

  - by Propeller

  I just bought an eMachines eM355. The default installed OS is MeeGo so I installed Windows 7 into it instead. The problem, however, is that, the on-screen indicators have disappeared. The ones I'm talking about are the small dark boxes that appear at the bottom part of the screen when you, for example, press Fn + Up Arrow (to adjust volume). The same goes for the brightness adjusting and the rest of the Fn key combinations. The keys do work but I'd still prefer to see a prompt on the screen. Another reason why I want to solve this is because I can't effectively toggle the Bluetooth and Wifi since I don't get any prompts when pressing Fn + F3. I wanted to include a picture of what I'm looking for but I couldn't find the exact term for such.

• Same album repeatedly updates when syncing iTunes with iPhone

  - by Unsliced

  I have many many albums and tracks purchased via the iTunes store both through iTunes directly and via the iPhone. They all synchronise properly and are on iTunes eventually (i.e. if purcashed originally on the iPhone). There's one album, though, purchased via the iTunes app in June this year. Virtually every time I sync the iPhone it says "updating files" and this album gets updated. The rest of the sync goes just fine, new tracks added, listened to podcasts are removed, playlists are updated (notwithstanding that smart playlists' orderings are now utterly broken) fine - but this album is always getting updated. In finder I've looked at the permissions and nothing seems unusual. FWIW, I'm on Mac OS X 10.5.8, iPhone 3.1.2, iTunes 9.02. Anyone with any ideas? It's not a fundamental problem, but it does means that each sync takes an extra 30-60 seconds, which is annoying!

• MSSQL, ASP.NET, IIS. SQL Server perfmon log question

  - by Datapimp23

  Hi, I'm testing a web application that runs on a hypervisor. The database server and the webserver are seperate vm's that run on the same hypervisor. We did some tests and the functions perform ok. I want you guys to look at a screenshot of a permon log of the sql 2005 server on the busiest moment. The webserver perfmon log looks fine and it's obvious that we have enough resources to present the page in a timely fashion. http://d.imagehost.org/view/0919/heavyload http://d.imagehost.org/0253/heavyloadz.jpg Zoomed out The striped blue line maxing out is the Processor que length (scale 100,0) The green line at around value 30 is Available MBytes (scale 0,01) The rest of the counters are visible on the screenshot. The sql server machine has no CPU limitations on the hypervisor resources and has 5 vcpu's and 5 GB RAM. Can someone help me to interpret this log. Thanks

• 2 HDs in RAID 1 with 2 partitions ?

  - by Prix

  Hi, i am not very familiar with raid partitons and am not even sure if this is the right place to ask about it, but i hope that if it is not that some one can point me on the right direction. This is my situation, i have 2 500 GB hds and a 3ware pci-e hardware for raid and i wanted to make a RAID 1 but i dont know if i can make more then one partition for it, for instance: MAIN HD: os partition: 100GB data partition: rest of left size and make the RAID 1 either work on all the HD or just on the data partition of it. that is on windows xp sp3 and the 3ware allows bootable raid.

• Booting Windows off new SSD from grub boots old Windows instead

  - by wuputah

  After a new SSD install, I have: Original Windows 7 on sdc1 (to be retired) Copy of Windows 7 on sdb2 A Windows system partition on sdb1 Ubuntu 12.04 on sda, /boot and ergo grub is on sda1 Grub is MBR on sda and set to boot from BIOS. I prefer to not change this; grub is great! I've run update-grub (the Ubuntu grub scripts are, at present, unaltered) and grub seems to be correctly configured as all options are available: I can boot any of the 3 Windows partitions and Ubuntu. I also ran the repair tool to get Windows to add both installations to BCD. The problem: choosing particular options seem to have no effect; the old version of Windows on sdc1 always boots. I'm stumped! My thought was to only boot Windows off sdb1, and then let BCD do the rest (present a menu to boot between sdb2 and sdc1, but I can't seem to get BCD to boot sdb2), but this has been unsuccessful. Reference: BCDEdit output

• Is WinRT really as secure as it's made out to be?

  - by IDWMaster

  Prior to releasing Windows 8, Microsoft claimed that all WinRT apps are cleanly removed from your computer after uninstalling them, and that WinRT apps should not interfere with other running applications, because they are ran in a "sandboxed" environment. Microsoft has also claimed numerous times on Channel9 that Windows 8 apps are not ran in a VM. So my question is; are these claims accurate? If the application is not running inside of a VM, how is it possible to protect the system against malicious code at runtime, assuming the attacker was able to bypass the screening process of the Windows Store system? Microsoft allows "native code" in WinRT apps, so wouldn't it be possible (using hand-coded assembly or some odd pointer manipulation trick to call functions outside of the sandboxed environment and interfere with the rest of the system, if it's really "native code" and not some VM?

• Sending a large number of mails causing problems on CentOS 6 / Plesk 10

  - by papakost

  I have a VPS running CentOS 6. When the system tries to send daily newsletter, after some time (e.g. after sending about 2000 emails), I get error "Unable to send mail" and the system memory goes really high. Till this moment, the mails are delivered normally. The rest symptoms are: I cannot see anything on /var/log/maillog (File seems not to be written) All files on /var/spool/mail have 0 bytes size. From time to time on httpd log I get errors like: /usr/sbin/sendmail: error while loading shared libraries: libc.so.6: cannot open shared object file: Error 23 "Activate mail service on domain" setting in Plesk is deactivated. Any idea on what's going wrong here?

• Ubuntu + LigHTTPd: Server requests taking ages

  - by ctrl_freak

  I've had an issue since upgrading my distro a couple of weeks ago from hardy; receiving data after making a request has increasing intervals of nothing, as you can see from the picture below. http://i49.tinypic.com/2w5lvr9.png I have since reinstalled fresh from an Ubuntu 10.04 Server (i386) disk, but am still having the same issues. I'm running on a LigHTTPd, MySQL, PHP5 stack. The surprising thing is, that local browsing using lynx is super fast, as expected. Initially, after reinstalling, I copied over the old configuration files from the previous installation, but have since reinstalled LigHTTPd and rebuilt the config file from scratch. The only correlation I could find, was that I attempted installation of ionCube and Zend Optimizer for a script I was testing, however I would think that it could no longer impact seeing I had reinstalled the OS. I have also removed Suhosin just in case, however it had no impact. I'm thinking it possibly has something to do with networking, but I wouldn't know where to start. The server is manually assigned an IP by it's MAC address on the router. The fact that the time seems to be exponential (to a point) worries me. I've tried strace'ing the LigHTTPd and MySQL processes, however I couldn't see anything obvious, not that I'd really know what I'm looking for. RAM and CPU usage don't seem to be out of the ordinary, but I can't say its perfect.. I'm hoping someone has experienced the same, or can point me in a direction, as searching has proved fruitless as I don't know anything specific. Config files can be posted, if requested.

• "Press Tab to search <site>" in Chrome not working

  - by YatharthROCK

  The problem After partially entering a URL like meta.st, Chrome adds in the rest of the URL slected in blue and says "Press Tab to search Meta Stack Overflow". But on pressing, it just moves the cursor to the next item like in a normal text-field. Other info I'm on Windows 7 Home Basic. My Chrome version number is 22.0.1229.52 beta-m (beta channel). This was working before. What I've tried I've reported it in Chrome (by going to Options Tools Report an issue...). I've also tried deleting all my custom search engines (they might've been interfering) and also tried creating a new profile. I also googled, but to no avail. How do I fix this? Thanks.

• Finding throuput of CPU and Hardrive on Solaris

  - by Jim

  How do I find the throughput of a CPU and the hard disk on an OpenSolaris machine? Using mpstat or iostat? I'm having a hard time identifying the throughput if it is given at all in the commands output. For example, in mpstat there is very little explanation as to what the columns mean. I've been using the syscl column divided by time interval to find the throughput but to be honest I have no idea what a system call truly is. I'm trying to to analyze a hardrive and CPU while writing a file to the hardisk and when at rest.

• AppFabric named cache, what happens if you lose a cache host?

  - by Liam

  I'm getting my head around how app fabric clustering works and there's something I'm not sure about. Given a structure where we have one named cache, with two lead hosts and (say) three cache hosts and high availability turned off and the lead host(s) performing the management role. When one cache host goes down do you loose the data that was on that cache host? In this MSDN article it states: Data on the non-lead hosts would be lost (assuming high availability was not enabled), but the rest of the cluster could continue serving and storing data But I was unsure if redundancy is built into the system. Would you loose x amount of data or would one of the other cache hosts store this data also and pick up the slack?

• Do I need to reserve space before installing Ubuntu alongside Windows 7?

  - by CRM Junkie

  I had Windows 7 32 bit on my existing system, but I am planning to install Ubuntu alongside it. So, I just decided to do a fresh installation of both the operating systems. When I insert the Windows 7 DVD, I can create 3 partitions at maximum, with one being the one where Windows 7 will be installed. I just wanted to know – do I need to keep some un-partitioned space for Ubuntu to install? By "unpartitioned space" I mean the space left after creating 3 partitions for Windows 7. I have a 500 GB HDD, so the three partitions I would be creating are 120 GB, 120 GB and 120 GB. The rest is shown as some logical drive, is that unpartitioned space? Can I install Ubuntu over there? I am pretty sure the space shown as logical won't be available as drives when I log into Windows 7. Is that space lost or can I use that to install ubuntu?

• In Windows 8.1, how can I configure File History to backup *some* of my SkyDrive folders?

  - by Matthew

  I want File History to back up all of the folders in my SkyDrive except for the media folders (Music, Pictures, Videos, Podcasts). My media folders are "available online only", the rest of "available offline". Right now File History does not back up any of the content in my SkyDrive, and I can't seem to find a way to configure which folders it backs up. I found some sources that say if my SkyDrive is available offline, it will be added to File History. But I don't want to make my entire SkyDrive available offline, just the non-media folders.

• How to partition my hard drive, quicker?

  - by Sam

  When I install Windows 7 on my hard drive, it makes three partitions. One with the OS itself, one with bootmgr inside (that is 100 MiB), and one with the factory image (all the crapware from HP). My final goal is to have the OS on a partition of 100 GiB and keep the rest (900 GiB) for storage. I thought it would be easy using gparted, but it is taking so long. It will take hours. There must a way to partition the drive before installing Windows. Yeah, because what I think makes the shrinking/moving of the partitions take so long is because they are not empty (am I wrong?).

• How can I search for Gmail conversations that have more than one e-mail? [closed]

  - by Matt Refghi

  I previously used a service that sent me Slashdot articles as individual e-mails. All I had to do was give them the RSS url, and they handled the rest. On the Gmail side, I simply made a filter, labeling these e-mails as "News". Once I stopped using the service, I realized that I had more than 20,000 such e-mails stockpiled. While I could delete all "News" e-mails, there are some that I've forwarded to friends, sometimes receiving multiple replies. These conversations are valuable - I would like to keep them. As far as I can tell, there's no way to search for conversations that have more than one e-mail in the thread. Up until now, I've been deleting them page by page, carefully de-selecting the conversations that have more than one e-mail; however, it will take far too much time to complete. Is there an easier way that I'm missing? Thanks.

• SharePoint Calendar - Start time after a certain hour

  - by KodovaKim

  I am working with SharePoint Calendar list to create a shift schedule for a team (End user side of things, I am not writing code). I have added a few custom columns to the Calendar List Item. I have the list exported to excel where I have a Pivot table set up so I can see a summary of the different columns - I can see the person's name (From the title column), total hours they are scheduled for (separated into weekdays and weekends based on a custom column I added). What I need is a way to check the start time of the shift to determine if it is a Day shift (starts at 7am), Eve shift (starts at 3pm), or a Night shift (starts at 10pm). So, when creating a new calculated column I would assume the function I need would go something like "=If([StartDate]...." but I am not sure on the rest. Anyone know how I would write that function?

• Configure browser and VPN traffic

  - by Zachzor

  Hello everyone. I've been having a few issues with my company's VPN server. The VPN is running on a Mac Server (10.6.x) and I'm also using a Macbook (10.6.5). I've been building specific programs to gather information from IPs, and to work on this while I'm at home I need to go through our VPN to access the network. Unless I send all traffic over VPN, I'm not able to hit those specific IPs. However, I'm unable to access the internet through my web browser when I send all my traffic over VPN. I was wondering if there was a way (besides setting up a split tunnel) that I could set up a web browser to go through my current wireless connection, as opposed to going through the VPN like the rest of my applications. Wether the browser be Chrome, Firefox, or Safari doesn't matter to me. Anyone else run into this issue and find a clever way to solve it? Thank you!

• Route a specific user's traffic via VPN but still allow local networking

  - by wbg

  So, I want to route certain traffic via a VPN connection and the rest via my normal Internet connection. I want to run several different programs and most of them don't support binding to a specific network interface (tun0 in my case). I've managed to send a specific user's traffic via the VPN following the answers given here: iptables - Target to route packet to specific interface? But unfortunately, when I run a server that connects to the Internet and has a web interface running on a local IP (127.0.0.1/192.168.0.*), all the Internet traffic correctly goes via tun0, but I'm unable to connect to the web interface from a local IP as a different user. When I log in as the VPN-ified user, I can access services running on local IPs, but other users/machines can't access any servers I start. Can anyone point me in the right direction?

• Swappable hard-drives for laptop

  - by lacqui

  I am bringing my old laptop for recycling, and removed my hard drive beforehand. The drive is a 320GB SATA drive, which is the same as my current laptop's drive. I would like to be able to easily swap between the two drives, in order to dual-boot that way. My laptop (Toshiba Satellite A500) needs a tiny Philip's screwdriver to get at the hard drive bay. I would like to replace that with something that is more easily changed, while still allowing the hard drive to rest on the desk. It can stick out a bit due to the laptop's feet, but not too far.

• Why is my nginx alias not working?

  - by Rob

  I'm trying to set up an alias so when someone accesses /phpmyadmin/, nginx will pull it from /home/phpmyadmin/ rather than from the usual document root. However, everytime I pull up the URL, it gives me a 404 on all items not pulled through fastcgi. fastcgi seems to be working fine, whereas the rest is not. strace is telling me it's trying to pull everything else from the usual document root, yet I can't figure out why. Can anyone provide some insight? Here is the relevant part of my config: location ~ ^/phpmyadmin/(.+\.php)$ { include fcgi.conf; fastcgi_index index.php; fastcgi_pass unix:/tmp/php-cgi.sock; fastcgi_param SCRIPT_FILENAME /home$fastcgi_script_name; } location /phpmyadmin { alias /home/phpmyadmin/; }

• Running 32 bit SQL Server 2005 on 64 bit Windows Server?

  - by TooFat

  If I have a 32 bit version of SQL Server 2005 running on a 64 bit Windows Server does the max amount of memory avail. the SQL Server process increase from 2gb to 4gb. In reading this blog entry by Mark Russinovich in which he states that "All Microsoft server products and data intensive executables in Windows are marked with the large address space awareness flag" and "Because the address space on 64-bit Windows is much larger than 4GB, something I’ll describe shortly, Windows can give 32-bit processes the maximum 4GB that they can address and use the rest for the operating system’s virtual memory." which leads me to believe that the answer is "yes" but I not totally confident.
