How much memory (RAM) would the average LAMP production server use, assuming little-to-no traffic, barebones except Apache2, PHP 5.3, MySQL5 installed and running?
I have a bunch of png files that I want to rescale.
Oversimplifying a little, let's say I have files named:
[email protected][email protected][email protected]
and so on, and I want to make:
apple.png
orange.png
pear.png,
and so on, with the output files all at half the scale of the corresponding input files. Is there a good tool for that? I have about 200 input files, so preferably the whole process would be automated.
First, a little background. I've recently been taken on as a web and software developer for a small company, who has no other in-house IT support. They've been asking my opinion on lots of IT subjects that are quite far out of my comfort zone. I'm definitely not a network admin.
Their IT consultancy contractor is pushing them to upgrade their dedicated exchange server, even though it seems like the one they currently have has a lot of life left in it and is running problem free. They say it's "coming to the natural end of it's life". They want to install a monster with a Xeon E5-2420, 32GB RAM, 2x 1TB HDDs, Windows Server 2012 and Microsoft Exchange 2010. They want to charge a small fortune for it. Basically, this system seems massively over the top seeing as it won't be doing anything else other than running as an exchange server for a company with less than 25 email accounts. My employers also have a file server system in-house that hosts three web apps, an SQL server, their local domain, print server and shared folders. That machine is using the same specs as the proposed new one, and it is barely using any of it's potential.
I asked if Microsoft Exchange 2010 could be installed on their file server, but they said that MS Exchange can't run on the same system as an SQL server because for some reason they will eat up each others resources (even though the SQL server isn't touching 1% of the current system's CPU or RAM).
My question is really, are they trying to rip my employers off? Could MS Exchange be installed on their other server (on a virtual instance or not), or does the old one even need replacing at all? Going with their current suggestion will cost the company in excess of £6k, and it seems entirely unnecessary.
I apologies, because I know this is probably a little thin on details, but if I carry on I could end up writing a massive essay that no-one will want to read. I've been doing my research, but I'm not knowledgeable enough make any hard decisions. Let me know if you need any more details.
Thank you for any help you can offer.
Further Details:
The new exchange would need to support Outlook Web App, 25 users, a few public mailboxes, and email exchange with Blackberries.
One of the very few reasons I have to physically interact with my Windows Home Server is to back it up to an external hard drive, with the "Backup Server" feature.
It would be more convenient to plug the external drive in to a desktop PC, and then do the backup over the network.
Is there a way to do this?
I've heard a little about iSCSI, but as far as I can tell it costs money, and I'm hoping for something free.
I want to be able to leave multiple external drives connected to an SBS 2008 server and select which drive is used as a target for the backup without physically connecting/disconnecting the drive.
Windows doesn't support this and my testing confirms that if 2 drives are connected there is little to no rotation between the target drives, the backup will run to the last drive it used if it is connected. Anyone have a script that will disconnect and reconnect a physical drive?
Thanks!
I've recently taken over management of a Windows 2003 Small Business Server and network for a small, less than ten person company.
I have some (antiquated) sysadmin experience, but I've little experience with Exchange.
The documentation of the existing infrastructure leaves much to be desired, and I was wondering if there's any sort of "So you've just become sysadmin" guides that anyone could recommend.
My technical support staff is only a little familiar with IIS and that's only as far as install goes. They need to install/update and configure ASP.Net web applications and WCF services that we write. Does anyone know any good tutorials/books/web sites that can help them understand some of the basic concepts of web applications and maintaining them on IIS?
I've seen several screencasts (recorded on Mac OS X) which show a nice little "toast" indicating which shortcut key is being pressed by the screencaster, typically in the middle of the screen. Is this a feature of the screencasting software? Is there an app that does this that stands alone?
I regularly do presentations for programming classes, and I want a way to show my audience what shortcuts I'm activating.

Hi,
I found that under Ubuntu, WICD and command "/sbin/iwlist wlan0 scan" give a little different list of wireless networks. Windows 7 also gives a slightly different list. For example, there is one shown in WICD but not in the command nor in Windows 7. I wonder why? How to get a complete list of wireless networks?
Thanks and regards!
Hello,
I'm using Zend Framework but I have a little problem:
How could I redirect internal all requests from
localhost/zendframework/
to
localhost/zendframework/www/
What have to put into my .htaccess in the folder localhost/zendframework/?
Like any other Apple product, OS X prides itself on the little details. When, earlier last week, I used my professor's Mac briefly to give a quick project presentation (mine decided to do a chkdsk at the wrong time, heh), I got the distinct feeling some were put intentionally to make the uninitiated look stupid.
What are the small usability details that Windows and Linux users will trip on when their Mac using friend lend them their beloved Mac for some quick web browsing?
I have looked at the official sites documentation, and it is a little tough to find starting points.
Is there a free comprehensive guide that is easy to understand for someone that has never dealt with mod_security?
I don't remember this happening before, but now whenever I play any video in iTunes (podcast video, movie, TV show, iTunes extras stuff but the menus work) it just shows a black screen with the sound playing. If I stop it, select "Computer" in the little output control on the iTunes video control panel that pops up, then play again, it works fine.
What the heck?
Tried rebooting, updating, with and without external monitor.
OSX 10.6.6
Tried using direct connection using Ethernet cable and using windows easy transfer, but no luck, also tried using ad-hoc, home group, and connecting through a router both wired and wireless but no luck, im getting a little frustrated as I need to transfer these files because im selling one of them this afternoon!
All I need to do is transfer some documents and files.
The windows 7 pc recognizes the vista pc but vista cant recognize the win 7.
How can I limit the number of concurrent CGI invocations in Apache 2.2.x?
More specifically, my problem is this: I have Apache hosting a Bugzilla instance and other stuff on one server. There's very little legitimate concurrent use of Bugzilla. However, it's trivial to mount a Denial of Service attack on the whole server by ignoring robots.txt and simply fetching a lot of bug pages that fork a process and hit a database.
I only googled out this article, but it's using apt-get to automate the installing.
I even don't know the name of fastcgi version of php,is it still named php or something else?
I'm installing apache/php from source code, can someone guide me a little?
Thanks!
I am a little frustrated having to use to separate USBs for booting on mac and windows. Is there a way that I can have the version for mac and the version for windows on one USB? or even better, one version that can be booted on both? I have heard of multibootiso, but I'm not entirely sure that it will work on imac.
If needed, I am willing to use terminal to make this happen, even if its a long complicated process.
I use a local DNS-Server (MicroDNS) which I set via netsh to redirect any query to my own page. A little webserver running inside my software answering something like "this page is not whitelisted". It works when connected to the Internet but does not work when offline. The Browsers stop looking up the DNS.
How could I make Browsers go to my page, whatever I enter in the address line, WHEN OFFLINE?
I've searched all over the internet for an answer to this and I can't find one. If I purchase a wireless N router, with greater range than my current G router will the range of the wireless G signal go as far as the wireless N signal? I say this because Wireless N routers are supposed to be compatible with wireless G devices. Is the wireless G a lesser signal coming out of the router?
Sorry if I confused you, I am a little confused myself.
Hi,
I was wondering the steps I can take to change the localhost name to a test development domain name like "website.dev" on Win7 x64 ? Currently, when my test website builds its assigned to 127.0.0.1:81 but I want this to instead have a name like "website.dev" that is accessible on my local network ?
[and sure any Virtual PCs built on this local PC]
I think this is done via the hosts file but I am little unsure how to do this ? Would someone be able to assist ?
Thx
The Ohai docs are incomplete. Here's what I've been able to do so far:
I've created a custom plugin that adds one piece of node data called "my_custom_data"
it works when I load it manually in IRB
I've used the Ohai cookbook to get it loaded on the servers that need it
However, Ohai doesn't load it, neither during Chef runs nor if I run Ohai manually.
The docs, here, are of little use in answering this question. http://docs.opscode.com/ohai.html
I have both a HDD and a SSD in my computer and after installing Windows I moved things around a little to ensure that the OS is on the SSD but my user profile resides on the SSD (with a few exceptions). I used junction points heavily for that. Windows and most applications are fine with that and it works well.
Now I wonder whether I can in-place upgrade this to Windows 8 while retaining that exact setup or whether there is anything I can do to ease the upgrade process.
Hi,
I'm trying to shrink an Windows 7 XP Mode VHD file with little success.
I've been trying to use VhdResizer.
When I select my VHD file, it says "VhdExpand only supports fixed and dynamic VHD files".
My XP Mode VHDs are dynamic files.
Does anyone have any idea why it is failing?
Failing that, does anyone have a process which I can use to shrink my XP mode VHD files?
Thanks.
I think it absurd that a wireless game streaming solution is the *first to hit the market when a 1000mbps+ Ethernet connection would accomplish the same feat with roughly 6x the available bandwidth.
I can only assume that there must be some reason behind this or a limitation preventing this, but what?
150mbps wifi is in no way superior to a 1000mbps LAN connection aside from well wireless mobility.
Not only that but I have a secondary laptop and desktop which should by hardware comparison completely outperform anything the Tegra in the Nvidia Shield can do.
Is this all just a marketing scheme to force people to buy the shield for the streaming benefit?
Chief among these is that NVIDIA’s Shield handheld game console will
be getting a microconsole-like mode, dubbed “Shield Console Mode”,
that will allow the handheld to be converted into a more traditional
TV-connected console. In console mode Shield can be controlled with a
Bluetooth controller, and in accordance with the higher resolution of
TVs will accept 1080p game streaming from a suitably equipped PC,
versus 720p in handheld mode. With that said 1080p streaming will
require additional bandwidth, and while 720p can be done over WiFi
NVIDIA will be requiring a hardline GigE connection for 1080p
streaming (note that Shield doesn’t have Ethernet, so this is
presumably being done over USB). Streaming aside, in console mode
Shield will also support its traditional local gaming/application
functionality. - http://www.anandtech.com/show/7435/nvidia-consolidates-game-streaming-tech-under-gamestream-brand-announces-shield-console-mode
^ This is not acceptable for me for a number of reasons not to mention the ridiculousness of having a little screen+controller unit sitting there while using a secondary controller and screen instead. That kind of redundant absurdity exemplifies how wrong of a solution that is. They need a second product for this solution without the screen or controller for it to make sense... at which point your just buying a little computer that does what most other larger computers do better.
All that is required, by my understanding, is the ability to decode H.264 video compression and transmit control/feedback so by any logical comparison, one (Nvidia especially) should have no difficulty in creating an application for PC's (win32/64 environment) that does the exact same thing their android app does.
I have 2 video cards capable of streaming (encoding) H.264 so by right they must be capable of decoding it I would think.
I haven't found anything stating plans to allow non-shield owners to do this. Can a third party create this software or does it hinge on some limitation that only Nvidia can overcome?
(*) - perhaps this isn't the first but afaik it is the first complete package.
