Up-to-date recommendation for a home ESXi 5.1 server?

Hi,
a similar thread was here end of last year:
From: "Joseph Marton" <[email protected]>
Subject: What processor for a home VMware server?
Date: Sun, 02 Dec 2012 04:48:11 GMT
Message-ID: <f4Bus.4$[email protected]>
Lines: 7
[snip]
I'm planning to have a new ESXi at home for just testing VMs and my
"home file & media" server. On new hardware, main aspect is low power
consumption, so I was wondering, if a box with internal disks or some
iSCSI capable NAS, that will power down the disks during idle times
(e.g. QNAP) would be the better choice.
Perhaps somebody has done this lately, pointing out recommendations and
pitfalls to avoid?
Tx, regards, Rudi.
PS: the old ESXi at home is a retired, reused old Proliant, consuming
faaaar to much power...

processors, fully redundant power supplies and fans, 8 internal SAS
10k rpm and 15k rpm drives, 8 network interfaces and several other
add-ons.
But if only you personally are using these VMs, the utmost power saving
you get, if you power your server only up, if you need it. Assuming 40
hours work per week, some weeks out of home on vacation, some hours
sleep per day gets you easliy down to at least 50% power consumption of
a 24h/7d working server. And you will have to disconnect the server/PC
physically from the mains via an own mains switch to get down to zero
power consumption during power off - the power consumption of a server
in standby (for NICs and ILO management etc) can be more than 10W,
which I find quite bad if you really power down the server to save
energy - if you just power down servers for maintenance and
reconfiguration, that's of course irrelevant.

Typically VMWare has you modify the BIOS to not do any power-saving, although I suppose you could "sleep" the guest VM's.

How does one change the date format for PlayMemories Home folders?

I am using PlayMemories Home Version 2.0.00.11271 and have many folders within it which contain only photographs imported from my Sony DSC-H9. Unfortunately, PlayMemories Home insists upon dating all folders in a month/day/year manner; and this makes little sense if one wishes to have the folders listed in logical chronological order. How can I change the date format to year/month/day? Changing the name of each folder, one by one, will take a very long time! Your helpful advice in this matter will be greatly appreciated. Thank you. System information:
Operating system: Microsoft Windows XP Professional
Service pack : Service Pack 3
Memory: 1.5 GB
Processor:         Intel(R) Pentium(R) M processor 1.86GHz
Max. clock speed: 1.86
Manufacturer: IBM
Model: 1847W76
System language setting: English (United States)
User language setting: English (United States)

I too thought that the folder naming format was obviously wrong and couldn't find a way to change it. I do agree that placing photos in folders according to when they were taken is a great idea. I had been considering writing some software to do just that. After discovering that PlayMemories does it, I had it re-import all my photos. Then I wrote a small Perl script to rename all of the folders into year-month-day format. Included here is the Perl script. It only acts on a single folder - use it on the root folder where all the PlayMemories folders are. It will rename all folders currently in a month-day-year format. I used it without problems but of course there is no guarentee that it is error free. This should work with any common version of Perl. Tom # There should be one command line argument: the directory to act upon
if ( scalar(@ARGV) == 0 ){
print "Usage: RenameDirs <dir>\n";
print " Where dir is the directory containing the directories to rename.\n";
exit;
$mydir = $ARGV[0];
chdir $mydir or die "Couldn't chdir to $mydir: $!";
opendir(ROOTPHOTODIR, ".") or die "Failed to open the pictures directory $mydir: $!";
@allphotodirs = readdir ROOTPHOTODIR;
closedir ROOTPHOTODIR;
foreach $dir (@allphotodirs) {
if ( -d $dir ) {
  print "$dir is a directory";
  if ( $dir =~ /^(\d{1,2})-(\d{1,2})-(\d{4})$/ ) {
   print " and has the proper format: month $1 day $2 year $3 and will be renamed to ";
   $newname = sprintf "%4u-%02u-%02u", $3, $1, $2;
   print "$newname\n";
   rename $dir, $newname or die "failed to rename $dir to $newname: $!";
  else {
   print " but is not of the proper format\n"
elsif ( -f $dir ) {

OSX LION SERVER on Mac Mini for a home media server?

Would a Mac Mini with Mac OS X Lion Server be a good alternative for a home multi media movie server?
Has anyone done this?
If so please give advice or success stories vs. HP Home Media Smart Server (i added a link to the HP server)
http://www.hp.com/canada/products/landing/mediasmart/ex.html
I would really rather use a Mac product but not sure what Apple offers and if it will do the same or better than the HP Media Smart Server.
Again, any advice would be great.
Cheers,

It would make a great server. Bonus over Apple TV for example is that you have access via both wired ethernet and wireless. Plus if you load tools from XBMC, Firecore and others you have a significant media server. Cost is right too.
Many people are doing this - google mac mini media server or other for more info.
Total downside to any windows based system - dealing with constant anti-virus, major security hassels, lack of true media integration and PITA to update, etc.
You should be aware that Lion Server is not ready for prime time - it stil has significant issues if you are migrating from SNL 10.6.8. If you buy an apple fresh Lion Server mac mini you should have no problems.
You'll probably be pleased.

Seeking advice/recommendations on a wireless networked camera for personal home security

Greetings forum! I am in need of advice/recommendations for a medium quality (less than $200) camera that I can set to record via my Airport Extreme network. This is mainly for home security, to watch the main entry point of the domicile. Alerts and/or viewing live stream remotely needed; I am considering the following model and welcome any feedback from those with knowledge/experience. Has anyone used the following and if so, how would you rate such things as ease of use, compatibility, ease of set-up, etc.
Linksys - Wireless-N Internet Home Monitoring Camera
Model: WVC80N | SKU: 9506652
Thanks in advance.

I answered the questions that were asked. "What will be, will be"
If you want to talk about security in relation to malware in general:
While there are no known viruses that attack Mac OS X at the present time, it is possible for spyware to get onto your Mac.
So I go to lenghts to protect my user. A hosed system can be replaced but a compromised user folder is compromised forever. Along with all your important data like bank records, credit cards, ... I.e. your "identity" stolen.
The best way to avoid that is by using your built-in firewall which is industrial strength and/or a hard wired router, downloading only from "trusted" sites, installing all security updates and being careful about what you give administrative power to. It is also recommended to run day to day tasks from a non-admin account.
Don't use Limewire or any other P2P service to download your software, get it from reputable sources. In addition, always keep at least your users backed up, preferably a clone of your entire system on a separate disk. And put your sensitive passwords, bank accounts, credit card numbers in a "secure note" in a new keychain or in an encrypted folder.
If and when a Mac virus does appear it will be headline news and you can download the AV software then. If you feel you have to run an AV program I'd suggest ClamXav a mac friendly freeware app that is very stable with OS X. It will check for known virus signatures at any rate.
Hope this helps.

Recommendation for home wireless service in So Cal?

I need to purchase wireless internet service for new home in Southern California. I currently use ATT DSL. After briefly switching to ATT Uverse on advice of ATT customer service when I wanted to upgrade to faster service and old airport apparently stopped working correctly, it was a disaster. (There is a separate conversation on the Apple Forum about the experience.) After much hassle I switched back to ATT DSL and bought a new airport. Things have worked fine since, although my son still thinks it takes too long to download movies. We are a Big Mac household - iPad, iPad Mini, iPhone 5, two MacBook Airs, iTouch - and an oddball Droid phone. New home currently uses Verizon phone and internet service through Time Warner (I'm choosing to go with Direct TV).
So my questions - Does Verizon wireless internet service work well with a household full of Macs? I prefer to use an Airport. Is there a modem and/or router that Verizon uses that is good or bad? Fios or DSL? (I had a horrible experience with the modem/router with the Uverse disaster.) Has the modem/router/Mac connection improved with Uverse? Or should I just stick with what I know works for me - ATT DSL even though its not the fastest speed?
I'm not technologically sophisticated (this is probably obvious), so would appreciate replies in plain English. Thanks!

DSL is yesterday's technology:
BEST is Verizon FIOS (or ATT Uverse) depending if either has fiberoptic cable to your door (call each to find out; they will know from your address). Be careful, ATT is now calling their non-fiberoptic service Uverse; so ask about fiberoptic!
I use Time-Warner Internet at its fastest consumer speed. I am currently uploading a 16GB file to an associate in UK and it will take 18 hours (remember upload is always much slower than download). I think my service is 20 or 30 down and 1 up; at about $40/month. I have multiple routers to connect it to many Macs, iPhones, AppleTVs, home entertainment systems, etc.
Stay away from satellite; it is ONLY for internet service to the boonies...
FYI: I use DirecTV (and a roof-top antenna) for TV and T-Mobile for both VoIP at home and iPhone 5. Everyone HATES the Time-Warner cable service due to their monopoly in So. Cal.
T-Mobile has best monthly rates in So. Cal for iPhone 5 AND you can purchase additional data for tethering (using your iPhone as a WiFi HotSpot or with BlueTooth, as I use it at an off-line office that has no internet service). AND you can talk and internet at the SAME TIME, unlike Verizon which on the iPhone is one or the other.
Soon T-Mobile will implement their UMA/WiFi Calling feature for the iPhone; already implemented on Blackberry, Android and other phones. This allows FULL T-Mobile talk and text coverage ANYWHERE in the world where you have access to WiFi. I use it with my Blackberry on every trip to London or at my girlfriend's house in the hills above Santa Cruz by swapping the SIMM card, now with micro-SIMM adapter.

Can I use the same plan that I have for my iphone 4s with my new ipad? or do I have to buy a new data plan for my new ipad? I would love to use my new ipad away from home but not sure how to use it?

Hardware/software recommendation for video capture prior to edit on home ba

i am a FCP user on a G5. i need to begin to load and initially edit video while traveling and then take that FC project file and load it onto my home based G5 for further work. i am considering a macbook and FC express to accomplish this task.
my questions are:
does it matter that the new macbooks are intel processors and my G5 is not intel based? will i have any compatibility problems with SW/file transfers.
is FC Express the best SW to use for the load and initial edits?
is there a best practice recommendation for what i want to do?
thank you.
dennis
G5 Mac OS X (10.4.9) use FCP HD 5.0.1

FCP will run on a MacBook. It's not support, and the Studio is not supported because of Motion's graphics requirements, but quite a few people are running FCP on basic MacBooks. Just make sure it has enough RAM.

Firefox users cannot presently exercise choice, to opt-in or out of "data collected for improving services." As a result, Firefox is constantly dialing home, sometimes four times a day or more up to 48 times a day. There is some over-stepping and redunda

I understand the charter on this is to "check-in" once every time the program is turned on, and then once every 6 hours after that, or, once every 24 hours presumably. But the phone-home-effect is over-stepping these basic parameters. If a user turns their browser off and then on, Firefox is still obligated to "check-in" even if it just checked in 3 minutes prior. If the coding is not pre-designed to overstep, or act excessively in a redundant focus, the instance of once every six hours or once every 24 hours, is still overmuch if a user has been doing this (non-voluntarily-participating) for 9 months or longer.
== This happened ==
Every time Firefox opened
== This started when Firefox took up the initiative of "improving service. to end users" or similar idea, making the web safer for novice users, etcetera.

Opening question was truncated. Should read: "Firefox users cannot presently exercise choice, to opt-in or out of "data collected for improving services." As a result, Firefox is constantly dialing home, sometimes four times a day or more up to 48 times a day. There is some over-stepping and redundancy here. It would seem the practice of "improving service" has been accomplished with as much information as Mozilla has gathered in the last 6-18 months about its users habits. '''Isnt it about time to give users the option to opt out of that now that most the heavy liftiing has been accomplished?'''"

Recommendation for setting up Data Guard for EBS R12 12.1.3

Hello Experts,
I would like to get some experts opinion and recommendation on setting up Data GUARD for EBS R12.1.3 running on Linux based systems.
Firstly I would wanna let you all know that I am just geek in this subject matter so do excuse me for any mistakes.
While we are planning on setting up Data Gurad fro R12 what are the best practices to consider ?.
We have 2 node rac enabled database and would wanna have non-rac based physical standby, based on this I believe that having db tier on remote or standby site is enough ?
if db node is enough for standby location what are things to be done when a fail over / switch over / role transitioned to standby for the app node from primary site to point db on the
standby location or do we have to have both apps and db tier @ stand by location
--However having a apps tier/node at standby will be of no use as we are planing to run db on mounstate meaning not a active data guard setup.
Please do reply with your recommendation/suggestions/pointers
Thanks in Advance.

How is the Cell Boundary Recommendations for 2.4Ghz Data survey in 802.11N

How is the Cell Boundary Recommendations for 2.4Ghz Data survey in 802.11N?

bYou can use N on 2.4GHz. You will have to use AES encryption or open SSID, 5.0 GHz channel bonding is to give 40MHz wide channels and double the data rate, plus a little as it can reuse the edge frequecies.
Basically you have upto MCS15 144Mbps at the top end per channel, don't bond 2.4GHz as there are not enogh non overlapping channels.
As for the low end it all depends. I would certainly disable the 802.11b data rates as a minimum but that means you still have very large cells and potential for interference. generally I would look at 24Mbps and switch everything off below that especially if you have very few 802.11b clients.

Individual cell data buttons for each app keep turning on by themselves?

I have a 4S iPhone, OS 7.0.6, and my problem is that the individual cell data buttons for each app keep turning on by themselves. I'll go in and turn them all off and the next time I look (whether in 5 min or 5 hrs) they are all turned back on again? I want to leave my cell data on so that I receive my iMessages but usually don't want everything else turned on until I get to a wifi zone. I used to be able to keep them all off until I did the last couple iOS updates. Help!

Hey there Tylyssanna,
It sounds like your cellular data options are not saving correctly. I recommend starting by turning off Cellular Data in Settings first. Then close all the running apps:
iOS: Force an app to close
http://support.apple.com/kb/ht5137
Double-click the Home button.
Swipe left or right until you have located the app you wish to close.
Swipe the app up to close it.
When you have done that and restart the phone, turn it back on, and test the issue again:
iOS: Turning off and on (restarting) and resetting

Thank you for using Apple Support Communities.

What CGI scripts are recommended for form2email?

My site is on register.com. I'm trying to use a script from form2email.net which was recommended by that host. The Dreamweaver code for the form looks fine to me. The script (written in Perl) executes, goes to a thank_you page, sends an email with correct from, to and subject. But the body of the email has no data except for the value of the submit button and info the script adds to any email it sends. I modified the script for my app using Notepad ++, changing only user-specified fields that had to be changed. I'd appreciate thoughts on what might be wrong, or a recommendation for a form2email script that works well with Dreamweaver.
register.com says they can't help with "coding problems," though they recommended the script, and I couldn't find help for my problem at the developer's site.

Why do you have 2 form tags on your HTML file?
The reason why you're getting just 'Submit: [Send]' in your e-mail is because you're closing your actual form before your 'submit' button and starting another form just for the 'submit' button.
Your formmail script interprets the only value is your '[send]' and it just parses that as an e-mail to you.
Change your code this way:
