2 monitors on 2012 Core i7 13 inch model - any problems?

I have a Core i7 Macbook Pro 2012 13 inch model
I've done some reading up and have read in places that 2 monitors with a USB3 HDMI device is possible...
BUT... because it's a 13 inch model, and that will ONLY be able to have 2 screens with the laptop closed
Is this true?
Also... I've seen USB3 extensions for under £30 and also other Startech ones for more than double the price
Do the cheap ones have any problems that the more expensive ones don't?
Generally: do the USB3 extentions cause any undesirable problems?
Thanks

If the resolution of the external monitors approaches the limits of what is supported by the laptop's video card, and you are using applications that lean heavily on the graphics processing hardware, there may be some performance degradation. This may be even more so on computers like the 13-inch that doesn't even have a discrete video card.
USB monitors will be driven by the USB bus which is driven directly by the CPU, so as long as you have CPU capacity it should be OK, but again if you were doing CPU-intensive work that may impact the performance of USB monitors. Do note that USB monitors tend to respond more slowly than regular monitors, because USB monitors are limited to the speed on the USB bus (and affected by other loads on the same bus including hard drives and other devices you may have on it), while normal monitors are driven by very fast graphics hardware, which is often the fastest hardware on the computer and many, many times faster than USB 2.

Unable to install windows features on windows server 2012 core datacenter

If I attempt to install, remove, or get windows features via powershell in windows server 2012 core datacenter I get the following error:

I've also tried managing the computer remotely using another windows 2012 server using the server manager GUI. That causes the server manager to crash with the following error:

Hi,
I would like to suggest you first run get-windowsfeature command on the core locally not remotely. And if it works, then try to remote run it.
Invoke-Command -ComputerName CORE1 {get-WindowsFeature }

Which Macbook Air should i get? 11 or 13 inch model

Im 14 and i need a new computer. Mostly i use my computer for browsing, email, twitter, listening music, youtube and sometimes gaming. I like light laptops that i can when im in my bed, when im laying in sofa,... But now i cant decide what model should i get 11 or 13 inch model. I hope u guys can help me.
Jessica

Hi Jessica,
I think that the deciding factor concerning which size to get would be how you intend to use it. People who tote their macbooks around alot, such as sales people or executives (road warriors) and also students who need to take their computers to school, surely would benefit from the smaller 11inch version. In your case, if you are going to use it in a comfortable environment, such as in bed, or on the sofa, the larger 13inch model would be more beneficial,especially if you watch videos and play games fairly often. Even if you lug it around a little, to Starbucks or a friends house, or take it with you on vacation once in a while, I feel the larger model would be suitable for you.

Do I go with the MacBook pro or the MacBook air? I'm going into 8th grade and were required to have labtop. I Also edit videos for my YouTube chanel. Which should I get 13 inch model.

MacBook Air: thin, light, fast SSD storage. Cons: not upgradable, expensive.
MacBook Pro: cheaper, upgradable, better graphics card, more storage and RAM for the buck. Cons: not as light
you'll get more for the money with the MacBook Pro. the Air is better as a second computer for people.

All vm's in hyper-v 2012 core cannot initialize

Hi,
All vm's in hyper-v 2012 core cannot initialize.
there is ram and space in drive. Tried to run windows update and restarted hyper-V.
any suggestions?
Thanks

So on your other host, 10.21.0.150 (?), right-click on the folder 'virtualmachines' and select 'Properties'. Go to the 'Sharing' tab and enable sharing. You will need to specify the domain admin, in your case, to have full permissions to the share.
Note that I wouldn't really recommend your approach from a permissions point of view - rather, I'd create a separate account within AD for this, grant that user full permissions to the folder, and then provide these credentials from your Hyper-V host.
I'm not sure which OS you're using for hosting your 'virtualmachines' folder, but http://technet.microsoft.com/en-us/library/cc770406.aspx should provide additional information
for actually configuring your shares.
Further, I'd use a little more descriptive name than just 'New Virtual Machine' in order to help keep things more organized as your environment grows.

Share aanmaken:
1)Shares => klikken op SMB / NFS => Nieuwe subfolder aanmaken: SMBshare / NFSshare
2)subfolder klikken => maak share => bij rechten naar beneden scrollen => Domain admins: PG & RW, Domain users: RO
3)Update
Systeem beveiliging:
1)system => Network access configuration => Nieuw netwerk toevoegen
Name: Sharenetwork
Network/host: 192.168.1.0
Netmask: 255.255.255.0

Connect Z-schijf met SMB share:
1)RMB op SMB share
2)Map network drive
3)Pad SMB share intypen
4)connecten met share account of finish 1)Private storage en manueel ip adres ingeven
Beveiliging backup:
1)Active directory van S1
2)OP s1 zelf volledig nieuwe OU: "TEMP Accounts" aanmaken => accidentally delete afzetten!!
3)2USers aanmaken die lid zijn van de groep ("member of") Guest
4)Op S1 => C schijf => nieuwe map map aanmaken en delen
5)Op advanced sharing van gedeelde map => Guest 1 Full control => Everyone alleen read rechten
6)Testen op client of je op Guest1 tekstbestand kan aanmaken en via Guest2 op die share map niet.
7)Als het werkt Guest1 verwijderen en bekijk sharing permissions op Guest1 map
*Wat stel je vast bij verwijderen Guest1 via active directory:
De guest account wordt vervangen door een ander account met een lange naam
die full control heeft over de map
8)Guest1 terug opnieuw aanmaken, wat stel je vast?
Guest1 heeft geen rechten meer over de map en de aangemaakte account blijft staan
Recycle BIN:
1)Open Active directory administrative center
2)Klik op uw domein links
3)Rechts => enable Recycle Bin
4)Verwijder Guest1 op AD
5)Guest1 komt te staan bij deleted users/objects op Recycle Bin
6)Mogelijkheid om te restoren
7)Delete OU Temp accounts => Lukt niet onmiddellijk => Omdat er nog objecten in zitten
*Zoek op welke technieken je kan toepassen om een backup te nemen van je Active Directory. Bekijk uiteraard ook welke 2 manieren
er zijn om een backup van je AD terug te plaatsen (Authoritative en non-authoritative):
-13.1.1 Authoritative Restore
Dit proces herstelt de AD na bc een wijziging die ongedaan gemaakt moet worden.
AD wordt hersteld vanaf de backup, de backup overschrijft dan alle andere DC's met eventuele nieuwere informatie.
-13.1.2 Non-Authoritative Restore
Terugzetten van gegevens van de backup. Nadien ontvangt de DC updates van andere DC's die gemaakt zijn sinds de backup.
Backup S1:
Eerst probleem openfiler oplossen:
1)openfiler opstarten vanuit vmcloud
2)cd /etc/samba
3)vim smb.conf (toevoegen: strict allocate = yes) => eerst i voor insert => opt einde escape => :wq voor opslaan
4)/etc/init.d/smb restart
Backup zelf
1)Install windows backup in server manager => add roles => features
2)Open windows backup
3)Action => backup once
4)Different options => Custom kiezen => System State backuppen
5)Remote disk kiezen
6)pad share: \\of\smb.smb.SMBshare
7)Als backup mislukt, de aangemaakte files door de backup manueel verwijderen en backup terug opnieuw proberen
!!!Als openfiler ineens verdwijnd van domein, moet je de tijd nakijken van beiden systemen (moeten gelijk zijn met max 5min verschil)
Restore backup (authoritatief ingesteld)
http://technet.microsoft.com/ru-ru/library/cc816878(v=ws.10).aspx
1)Herstart de domeincontroller in Directory Services Restore Mode Remotely
=> run => Msconfig.msc => stapkes staan in url: http://technet.microsoft.com/ru-ru/library/cc794729(v=ws.10).aspx
2)Restore uw ADDS van je backup a.d.h.v. een non-authoritatieve restore.
Dit zorgt ervoor dat de domeincontroller terug in de staat komt waarop de objecten die verwijderd zijn
er terug bijstaan.
http://technet.microsoft.com/ru-ru/library/cc794755(v=ws.10).aspx
in cmd:
=>wbadmin get versions -backuptarget:\\of\smb.smb.SMBshare
=>wbadmin start systemstaterecovery -version:12/03/2013-12:37 -backuptarget:\\of\smb.smb.SMBshare -quiet
3)Markeer objecten als authoritatief zodat ze niet worden overschreven bij het restoren door synchronisatiefouten
tussen de verschillende domeinen.
http://technet.microsoft.com/ru-ru/library/cc816813(v=ws.10).aspx <== hieraan beginnen
=> open run => ntdsutil
=> activate instance ntds => enter
=> authoritative restore => enter
=> restore subtree "OU=Stagiairs,DC=Host,DC=net" => enter
=> quit => enter
=> Start terug op met de domaincontroller in normale modus dus dsrm opstartmode uitschakelen: Safe boot uitvinken
Nakijken of beide OU's Stagiairs en Guests er nog staan
(In dit geval is OU guests wel verwijderd doordat we maar 1 DC hebben dus de informatie
wordt niet gesynchroniseerd met een 2de DC)
- Debian Machine toevoegen:

Risico's gedeelde application pool:
   -1 proces per application pool (=>zwaar proces dat veel resources nodig heeft)
       (als dit proces vastloopt alle websites geimpacteerd)
   -gebruikers kunnen in principe aan elkaars bestanden
1)IIS installeren op S2 via server manager op S1
2)Role services in setup, volledig vanonder => management service aanvinken (dit staat remote management toe)
3)Op S1 Web server zoeken en enkel van IIS de management console installeren zodat IIS van S2 beheerbaar is
4)Powershell op S2:
Invoke-command -ScriptBlock{Set-ItemProperty -Path HKLM:\SOFTWARE\Microsoft\WebManagement\Server -Name EnableRemoteManagement -Value 1}
Invoke-command -ScriptBlock {Set-Service -name WMSVC -StartupType Automatic}
Invoke-command -ScriptBlock {Start-service WMSVC}
In IIS manager op S1 => Add connection => S2.premium.sdhost.net => account: administrator van S2
In IIS Manager => Sites => new Website, 2 website aanmaken
   -'klant1.sdhost.net' Physical path => C:\inetpub\wwwroot\Klant1 => hostname = Klant1.host.net
   -'klant2.sdhost.net' Physical path => C:\inetpub\wwwroot\Klant2 => hostname = Klant2.host.net
In DNS A-record toevoegen:
   -hostname: www
   -IP: 192.168.1.2
Voor toegang via IPv6 ook een AAAA-record toevoegen:
   -hostname: www
   -IP: fdac:1fff:b0b0:4bd0::2
Voor elke site ook een een CNAME-record aanmaken:
   -Alias name: klant1, FQDN: www.host.net
   -Alias name: klant2, FQDN: www.host.net
In deze standaardopstelling schuilen enkele risicoís. Geef twee risicoís die de huidige
configuratie (gedeelde application pool) met zich mee kan brengen:
- Als je een website hebt die zwaar CPU belastend is (zoals foto's herschalen) heeft dit ook effect op je andere websites
- Omdat je websites binnen dezelfde apppool zitten hebben ze eenzelfde identiteit en kun je geen aparte permissies opzetten.

Maybe you can do this tutorial to, it is a tuto for learning DFS & DNSSEC..
Wat betekent de optie “dnssecok”
   -> Deze optie stelt de dnssecOK bit in voor deze query
   -> Dit verteld de server that de client dnssec verstaat en dat deze server hiervan gebruik kan maken met deze client
Krijg je een bevestiging dat dit een secure antwoord is? (RRSIG)
   -> Neen want de zone is nog niet gesigneerd
Controleer of de client C1 ingesteld is om secure responses af te dwingen bij zijn DNS
caching server: get-dnsclientnrptpolicy. Resultaat?
   -> Het resultaat is niks, vermoedelijk omdat er geen instellingen zijn hiervoor
Probeer opnieuw een request op C1 voor S1 met ResolveDNSName. Is het signeren
van de zone voldoende om secure antwoorden te krijgen op de client?
   -> Er komt opnieuw geen RSIG record dus dit is niet voldoende
Om secure DNS responses op de client voor het domein securezone.lab af te dwingen
wordt in het domein Host.net een GPO ingesteld. (nieuwe GPO voor hele domein).
zoek op en stel deze GPO in voor responses van securezone.lab.
   -> default domain policy -> Edit =>   -> Computer Configuration > Policies > Windows Settings > Name Resolution Policy.
   "In the details pane, under Create Rules and To which part of the namespace does this rule apply, choose Suffix from the drop-down list and type sec.contoso.com next to Suffix."
   "On the DNSSEC tab, select the Enable DNSSEC in this rule checkbox and then under Validation select the Require DNS clients to check that name and address data has been validated by the DNS server checkbox."
   "In the bottom right corner, click Create and then verify that a rule for sec.contoso.com was added under Name Resolution Policy Table."
   => GPupdate /force uitvoeren
   => Dan kan de policy bekeken worden
Je zorgt er uiteraard ook voor dat deze policy toegepast werd op de client (C1) en controleer dit opnieuw met get-dnsclientnrptpolicy.
   => GPupdate /force
   => get-dnsclientnrptpolicy => levert hetzelfde resultaat als op de server
Opnieuw: ResolveDnsName s1.securezone.lab server S1 dnssecok Wat krijg je als antwoord te zien? Wat is de oorzaak?
(Distribueer) Kopieer de trust achor data van de secure.lab zone op S2 naar S1 en importeer die op de DNS van S1 als trusted anchor. (keysetsecurezone.lab)
   http://technet.microsoft.com/en-us/library/hh831411.aspx
opnieuw: ResolveDnsName s1.securezone.lab server S1 dnssecok Krijg je nu een (beveiligd antwoord)?
   ->Ik krijg nu een beveiligd antwoord van de DNS server gesigneerd door securezone.lab met geldigheidstermijn
p23 Distributed File System
Installeer op beide server de “file services role”.
   -> Add roles and features
   -> File services
       -> DFS
Maak een namespace aan (DOCUMENTATION) in je domein hOst.net. Stel de sharepermissions zo in dat de groep ‘auteurs’ schrijfrechten heeft. gewone gebruikers
mogen enkel leesrechten hebben.
   -> DFS manager
   -> Namespaces => Add namespace
maak een folder aan in de namespace DOCUMENTATION met als naam PDF
   -> Add folder
maak een tweede target aan voor de PDF folder
   -> Add target to folder
stel replicatie in tussen de twee folder targets. De inhoud wordt vanaf nu dus gesynct.
   -> Automatisch bij 2de target volg de wizard
Welke andere stappen zijn nodig om een volledig redundant DFS systeem op te zetten?
   -> De folder moeten via DFS geschared staan
   -> De replicatie moet ingesteld worden
maak een diagnostisch raport aan over hoe replicatie gebeurt, en corrigeer eventue vastgestelde problemen.
   -> Rechtermuisknop op de replication object
   -> Create diagnostic report
   -> kies de reports
stel quota’s in. In de map PDF maak je een subfolder CATALOGS aan, maar zorg dat die niet groter dan 10MB kan worden. Stel hiervoor een harde limiet in.
   -> install FSRM bij file services
   -> klik quotas => add quota => kies het bestand
   -> nieuwe quota => 10mb hard aanvinken
   -> save
   http://technet.microsoft.com/en-us/library/cc875787(v=ws.10).aspx
omdat we willen vermijden dat de volledige bandbreedte ingenomen wordt door DFS,beperken we de replication speed tot 2MBps.
   -> Klik op de replication -> rechterkolom kies vor edit replication group
   -> Stel de 2MBps in

2012 macbook pro 13 inch vs air 13 inch?

I need to pick between the 2012 macbook air 13 inch and the 2012 macbook pro 13 inch. I am a college student. Any ideas?

You should probably ask this in the MacBook Pro and MacBook Air forums. This is the forum for the discontinued white and black plastic MacBooks.

2012 Macbook pro 13 inch or the Macbook air 13inch?

I need to pick between the 2012 macbook air 13 inch and the 2012 macbook pro 13 inch. I am a college student. Any ideas?

I too had that decision to make when I bought my MBP 13 a month ago.
I liked the MB Air because of the portablity and the fact that it had a better screen resolution.
My deciding factor however, was the fact that the MB Air is not user upgradeable and I like the idea of having an optical drive just in case i need it.
If not having an optical drive is an issue to you, then the MB Air is perfect.
Keep in mind however, that if you decide to go with the MB Air, get the maximum RAM you can since you can not upgrade it in the future. Remember, as programs get upgraded, they become more memory hogs.
Just my .02 cents.

2 monitors on 2012 Core i7 13 inch model - any problems?
