  • Best approach to utilize RamDisk for Chrome?

    - by laggingreflex
    I use a lot of tabs and after a while less recently opened tabs take some time to become responsive, which I guess is because they're being un-cached to HDD as they're not required. So after creating a Ram-Disk I have two options, use --disk-cache-dir="G:/" switch to do what it does. Or what I'm currently doing: using a directory junction for "[...]\AppData\Local\Google\Chrome\User Data\Default" to move that entire folder over to Ram-Disk. I thought this would be better than just disk-cache but what do I know. Is it? As one can guess it'll be a pain saving/loading the Ram-Disk image each time I start chrome but if it really is better than the former approach I'll write a script or something.

  • Looking for the best ec2 setup for 3 sites totaling in 1.5 mil in traffic monthly

    - by john h.
    I am looking to consolidate our current aws setup of 2 Large ubuntu ec2 servers and 2 large RDS server for our 3 websites that have a total of about 1.5 million hits a month and increasing every month with the majority of traffic (1 mil) to one forum site in the group and the rest of traffic to an ecommerce site and a small wordpress site. So here is my question/thought? Would it be better for us to combine the two ec2 large servers to just one and same with the 2 RDS servers so we run all three sites off one large ec2 and one RDS. -or- Should we setup maybe 2-3 smaller ec2 servers load balenced and a single RDS. -or- Something completely different setup? One concern is that if one site crashes it takes with it the others. It happened in the past but I am pretty sure its because of the forum software and not the server setup. -john

  • Best MTA setup for home or laptop computers - not server

    - by thomasrutter
    Hello, What is a good MTA (e.g. Postfix or something else) setup for a home computer behind a NAT, or a laptop that connects to various different wifi networks? I've read a lot of Postfix tutorials on how to set it up this way or that, but they are usually geared towards computers that are servers ie they have a static IP have a domain name are always connected to the same network My requirements are, I guess: Ability to forward mail for "root" to another server of my choosing. No listening for incoming SMTP connections - outgoing only Ability to route outgoing mail via an external SMTP server with authentication (and perhaps encryption) If not Postfix, I need an MTA which can queue up mails in case it temporarily has no internet connection.

  • What is the best position for power unit?

    - by guest86
    I would like to buy new computer case. Last time I bought a computer was in 2008 and many things have changed up to day. Many new computer cases have power unit placed down, on bottom. I'm thinking about buying some of those cases, but i'm not sure about something - if power unit is placed on the bottom it can't take away hot air from the case and pump it out right? All my PC parts are silent - CPU (E8200, placed below 12cm Nochtua fan of power unit) has heat-pipe cooler with Nochtua fan spinning at only 800rpms, GPU has cooler powered by 7V instead 12 and that's why i don't want to HAVE TO place another fan to pump out hot air instead of PU placed on top. That might make some noise. So i ask someone more experienced: if i buy some computer case with PU placed down, do i HAVE TO place some fan to pump out hot air?

  • Best Way to Archive Digital Photos and Avoid Duplicate File Names

    - by user31575
    This problem pertains to archiving of digital pictures taken from multiple cameras. Answers here covered the general topic of the-mechanics-of-backups: How do you archive digital photos and videos ? I however face another problem. Having multiple cameras (canon) and multiple SD cards (mixed and matched at random), I have found that different SD cards have different photos with the same file name, i.e. two different photos each name IMG_3141.JPG. Additionally, for better or worse, I've backed up the files to multiple places and need to consolidate my backups. I want to eliminate duplicates, but not clobber files. The only way I can think of is to append the code (md5 or sha1) to the file name, i.e. IMG_3141.JPG becomes IMG_3141_KT229QZ31415926ASDF.JPG, then sorting them out Any better ways? (Note "open letter" address the 'duplicate file name' concern): http://photofocus.com/2010/09/13/an-open-letter-to-digital-camera-manufacturers-regarding-camera-file-naming/ )

  • Linux's best filesystem to work with 10000's of files without overloading the system I/O

    - by mhambra
    Hi all. It is known that certain AMD64 Linuxes are subject of being unresponsive under heavy disk I/O (see Gentoo forums: AMD64 system slow/unresponsive during disk access (Part 2)), unfortunately have such one. I want to put /var/tmp/portage and /usr/portage trees to a separate partition, but what FS to choose for it? Requirements: * for journaling, performance is preffered over safe data read/write operations * optimized to read/write 10000 of small files Candidates: * ext2 without any journaling * BtrFS In Phoronix tests, BtrFS had demonstrated a good random access performance (fat better than XFS thereby it may be less CPU-aggressive). However, unpacking operation seems to be faster with XFS there, but it was tested that unpacking kernel tree to XFS makes my system to react slower for 51% disregard of any renice'd processes and/or schedulers. Why no ReiserFS? Google'd this (q: reiserfs ext2 cpu): 1 Apr 2006 ... Surprisingly, the ReiserFS and the XFS used significantly more CPU to remove file tree (86% and 65%) when other FS used about 15% (Ext3 and ... Is it same now?

  • Best way to backup and restore millions of files

    - by bongo
    Hi, I'm facing a rebuilding of the volume on which I host the mail storage (kerio mailserver, which uses maildirs). I need to backup and restore as quick as possible the 3.5+ millions (for about 600GB) small files of the store directory. It takes more than 12 hours via rsync to a NFS share, but I also have a 1TB firewire 800 raid1 disk that I can use (from some preliminary tests it's faster). I'm working off a XServe intel. What is the fastest way to do it? Rsync? Finder copy? tar?

  • Best option for storage clustering

    - by sam
    I'm working on an application that requires a large amount of storage space and I want to handle storage 'in-house' (Much cheaper than, say, S3) so we will have multiple servers (Initially 4) with large amounts of storage (6TB each). The storage will need to be very flexible and configurable, each piece of data should be replicated on at least 2 servers and must be easily readable/writable from ether an API of a UNIX device/file/folder like a normal drive, I don't mind which. We must also be able to easily offload content to our HTTP CDN (Edgecast), it doesn't need to have built in HTTP support but if it doesn't I'm going to have to write something to get the files onto HTTP so they can be pulled by the CDN. I've looked at a lot of solutions including Eucalyptus Walrus OpenStack Object Storage MogileFS and some others which I can't remember All the servers will be running RHEL 6, they have 4x1.5TB drives which will be RAID1'd into a single partition. All the servers have 1GB/s connections between them and 100MB/s connections to the internet with unlimited bandwidth. They have 2x2.66ghz processors. I understand there isn't a single, perfect answer but it would be nice to get some pointers.

  • What's the best ramdisk for Windows?

    - by Dan Fabulich
    Just Googling for "windows ramdisk" returns a lot of stuff; some free, some paid. Can someone recommend a good one? (I'm willing to pay, but only if it's really worth paying for.) Here's what I'm looking for: Works on XP and Vista Supports 64 bit and 32 bit I'd like it to support more than 2GB of space (is that even possible on a 32 bit operating system?) I think I want something that can avoid swapping the ramdisk pages. (Though swapping would give me more free space; maybe I'll want to swap the ramdisk pages eventually? Is this configurable?)

  • SQL Server 2008 Express - "Best" backup solution?

    - by alexn
    What backup solutions would you recommend when using SQL Server 2008 Express? I'm pretty new to SQL Server, but as I'm coming from an MySQL background I thought of setting up replication on another computer and just take Xcopy backups of that server. But unfortunately replication is not available in the Express Edition. The site is heavily accessed, so there has to be no delays and downtime. I'm also thinking of doing a backup twice a day or something. What would you recommend? I have multiple computers I can use, but I don't know if that helps me since I'm using the Express version.

  • Best way to close nested streams in Java?

    - by dirtyvagabond
    What is considered the best, most comprehensive way to close nested streams in Java? For example, consider the setup: FileOutputStream fos = new FileOutputStream(...) BufferedOS bos = new BufferedOS(fos); ObjectOutputStream oos = new ObjectOutputStream(bos); I understand the close operation needs to be insured (probably by using a finally clause). What I wonder about is, is it necessary to explicitly make sure the nested streams are closed, or is it enough to just make sure to close the outer stream (oos)? One thing I notice, at least dealing with this specific example, is that the inner streams only seem to throw FileNotFoundExceptions. Which would seem to imply that there's not technically a need to worry about closing them if they fail. Here's what a colleague wrote: Technically, if it were implemented right, closing the outermost stream (oos) should be enough. But the implementation seems flawed. Example: BufferedOutputStream inherits close() from FilterOutputStream, which defines it as: 155 public void close() throws IOException { 156 try { 157 flush(); 158 } catch (IOException ignored) { 159 } 160 out.close(); 161 } However, if flush() throws a runtime exception for some reason, then out.close() will never be called. So it seems "safest" (but ugly) to mostly worry about closing FOS, which is keeping the file open. What is considered to be the hands-down best, when-you-absolutely-need-to-be-sure, approach to closing nested streams? And are there any official Java/Sun docs that deal with this in fine detail?

  • What is the best way to hide a command prompt window

    - by detj
    I'm running the headless interface of VirtualBox (VBoxHeadless.exe) with Ubuntu Server running on it. Every time I run VBoxHeadless, it starts a command prompt window which just sits on the taskbar taking space which could have been used by more useful programs. I want to hide this non-functional command prompt window (minimize to system tray or anything that just removes it visibly). How can I do this? It would be really cool, if this can be achieved without installing any 'minimize to system tray' utility. Any ideas??

  • IBM Thinkpad 240 - Best way to boot from floppy to USB - Best Linux for 300 MHz 128 MB RAM 800x600 s

    - by zillion
    Mostly I still have that old 'ultraportable' laptop that is mostly like a pre-netbook era laptop and a friend and programmer needs a computer because the one he was using just broke and he has to wait until the new one arrive in 4-6 weeks ... This laptop has no LAN connection and CD-ROM so be prepared for a real challenge! All hardware is well supported on Windows XP (included drivers on the Windows XP CD) and on Linux out-of-the-box (but the screen need a special configuration.) Mostly any Linux that will work well with Skype (USB or regular headset), any MSN client and a text writer for code will do. What I have tested so far: Slitaz 2 don't boot because the floppy of GRUB4DOS don't see the USB drive (fully working and tested on my regular laptop), Damn Small Linux was working but was needing a special screen configuration that I don't remember (in the boot options of the floppy) and now I'm thinking about Puppy Linux that is seen to work totally out of the box with it but I will need an old Puppy version (1 or 2 I think) and the Wakepup floppy ... If you got some ideas to help or to try I'm open!

  • Best practices for SQL Server audit trail

    - by Ducain
    I'm facing a situation today where it would be very beneficial to me and my company if we knew who had logged into SQL and performed some deletions. We have a situation where at least 2 (sometimes 3) people login to SQL using SQL Server Management Studio, and perform various functions. What we need is an audit trail. If someone deletes records (mistakenly or otherwise), I'd like to know what was done. Is there any way to make this happen?

  • Help Selecting The Best WebHost

    - by Joshua
    Can anyone recommend a user-friendly (I'm new to website development) and inexpensive web host (my websites are simple and small, so no need for a beef-eating server) that will allow me write access to the file system from PHP? My current web host won't allow me to write to the file system, and keeping everything in the database is slow, and a pain.

  • rails best practices where to place unobtrusive javascript

    - by nathanvda
    Hi there, my rails applications (all 2.3.5) use a total mix of inline javascript, rjs, prototype and jquery. Let's call it learning or growing pains. Lately i have been more and more infatuated with unobtrusive javascript. It makes your html clean, in the same way css cleaned it up. But most examples i have seen are small examples, and they put all javascript(jquery) inside application.js Now i have a pretty big application, and i am thinking up ways to structure my js. I like somehow that my script is still close to the view, so i am thinking something like orders.html.erb orders.js where orders.js contains the unobtrusive javascript specific to that view. But maybe that's just me being too conservative :) I have read some posts by Yehuda Katz about this very problem here and here, where he tackles this problem. It will go through your js-files and only load those relevant to your view. But alas i can't find a current implementation. So my questions: how do you best structure your unobtrusive javascript; manage your code, how do you make sure that it is obvious from the html what something is supposed to do. I guess good class names go a long way :) how do you arrange your files, load them all in? just a few? do you use content_for :script or javascript_include_tag in your view to load the relevant scripts. Or ... ? do you write very generic functions (like a delete), with parameters (add extra attributes?), or do you write very specific functions (DRY?). I know in Rails 3 there is a standard set, and everything is unobtrusive there. But how to start in Rails 2.3.5? In short: what are the best practices for doing unobtrusive javascript in rails? :)

  • Default Gateway solution on NAT'd network (best options)

    - by kwiksand
    I've recently changed a network from a bunch of machines exposed to the net on a network to a more security conscious Firewall-fronted network with a DMZ for public services. Everything's mostly working perfectly now, but I've got the old problem of NAT Loopback where a machine within the LAN wants to access a public service via the public/external IP. I've solved this problem previously in a small/SOHO environment simply using NAT loopback features of the router in use or a simple iptables rule to do the same, but I want to make sure I make the most resilient choice with the least concern. It seems I can: Use iptables as I've said to DNAT and MASQUERADE the change source/destination so the connection works correctly i.e iptables -A PREROUTING -t nat -d ip.of.eth0.here -p tcp --dport 8080 -j DNAT --to 192.168.0.201:8080 iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -p tcp --dport 8080 -d 192.168.0.201 -j MASQUERADE Use split DNS, with internal mappings for public IP's Potentially do some route nastyness by setting the Default Gateway to use a different externally exposed IP to then come back in the public route (messy) Someone mentioned putting the Default Gateway within the DMZ as well (on serverfault), but I can't find the post again. I'm sure this is a common issue for many with NAT'd networks, but I've not really seen the perfect solve all when it comes to fixing this problem. What is your opinion?
