When does proactive caching make sense?

Hi all!
An standard pattern for multi-dimensional cube is to have
one cube doing heavy time-consuming processing and then synchronize it to query cubes.
In this setup, will pro-active caching makes sense?
Best regards
Bjørn

Hello Jensen,
Proactive Cache is useful low volume data cubes where data is updating frequently like inventory, forecasting etc. But I will tell you with my own experience Proactive cache in SSAS is not worth. It behaves unexpectedly some times when data update/insert/Delete
in source table the cube doesn't start its processing , better you create a SQL Job to process the cube after specified time .
If you want to process the cube in specified interval then I would suggest you to go with SQL JOB

Hope this will help you !!!

Does EAP/SIM make sense for others than mobile operators?

Hi,
I'm wondering about the many different EAP authentication protocols. One of these is EAP/SIM (initiated by Nokia). I think the advantage of this authentication method might be the kind of key exchange. Users are familiar in using SIM-cards. Out of this consideration I have some questions:
* Is EAP/SIM as secure as EAP/TLS or EAP/Cisco?
* Does it make sense to use EAP/SIM as an WISP (given that the WISP is NOT a GSM/UMTS mobile operator)?
* What is the position of Cisco to EAP/SIM? Will Cisco support it?
Best regards,
Armin

Does getting Applecare make sense?

Hey,
I've been wondering this question for awhile. Should I get applecare?
It would make sense if it covered battery loss. But at 220$ Canadian [I do get an education discount] it is a lot of money.
Any advice / suggestion?

If you can't afford Applecare and you don't care if your computer breaks 2 1/2 years from now then don't worry about. If you are planning to buy another laptop next year don't buy it.
I would disagree with that plan. I've purchased an Apple laptop every two and half years for about seven years now and I always sell the "old" one with at least six months of an AppleCare Protection Plan still valid. This is a big selling point for some people as they know their new used computer will be free of factory defects and they can even get software support if you transfer the plan to the new owner. I believe it is worthwhile even if you're planning on selling your portable Mac. If the new owner doesn't want it, you can get a pro-rated refund from Apple for the portion of the plan you have not used when you sell your computer.

I'm confused - does it still make sense to upgrade to CS6 now?

Hi,
I wanted to switch from Mac to Windows in the near future and therefore upgrade from CS5 to CS6 (because apparantly it's not possible to switch my CS5 license to another OS).
Cloud version is a no-go for me, one reason is because I don't like monthly fees, I want to buy things and own them.
Now, with the CC versions announced and the discontinuation of the Creative Suite, I am not sure it even makes sense to upgrade to CS6 anymore? Would I invest in a more or less dead product?
Sorry if this is a stupid question, but I'm really confused about this.

Ok. nevermind. I decided to buy a new Mac and to continue using CS5 as long as possible while looking for alternative software.

Does my method make sense?

Hi my assignment was to create a link list implementation of an unordered set of integers.
so far i have this
public class Set<Value> {
Value Element;
Set<Value> next;
Set(Value data)
            Element=data;
            next=null;
        Set(Value data, Set n)
            Element = data;
            next    = n;
public interface MySet<Value> {
boolean isIn(Value v);
void add(Value v);
void remove(Value v);
MySet union(MySet s);
MySet intersect(MySet s);
MySet difference(MySet s);
int size();
void printSet();
public class MyLLSet<Value> implements MySet<Value>{
    private Set<Value> head;
public MyLLSet(){
    head=new Set(null);
public boolean isIn(Value v){
    Set<Value> p;
    p=head;
    boolean flag=false;
     while(p.next!=null){
        p=p.next;
        if(p.Element==v){
            flag=true;
return flag;
public void add(Value v){
    Set<Value> p;
    Set<Value> q;
    p=head;
    q=head.next;
    while(p.next!=null){
        p=p.next;
        q=q.next;
    p.next=new Set(v,q);
public void remove(Value v){
Set<Value> p;
Set<Value> q;
p=head;
q=head.next;
while(p.next!=null){
     p=p.next;
     q=q.next;
     if(p.Element==v){
         p.next=p.next.next;
         q.next=null;
         break;
public MyLLSet union(MyLLSet s){
    Set<Value> p;
    Set<Value> q;
    MyLLSet temp =new MyLLSet();
    p=s.head;
    q=this.head;
    while(q.next!=null){
        q=q.next;

        p=p.next;
        if(!this.isIn(p.Element)){
            temp.add(p.Element);
    return temp;
}do my methods make sense so far.. i am completely new to porgamming.. i just want to know if I am going in the right direction...if u see anything unusual in the Set, mySet or the MyLLSet class..please let me know.. any comment would be greatly appreciated...
*Note = the union method combines the lists together, if there are duplicates, it rejects them
*Note= the isIn method returns true or false if there is an element present or absent form a list respectively

well its due on tuesday
and i cant compile it because all the method implementations from the interface class have to be implemented first for it to compile..
and I have modified my code
and it gives an error (method is not abstract therfore an error (union method)).. i guess its because i changed parameter type in the union method.. i dont know how else to make it work.. here is my code.. any comments would be greatllllllyyyy appreciated

HT4203 Does this really make sense to others...?

...that we are not able to receive text messages containing photos if using the iPhone through wifi? Like many others I'm sure, I tend to keep my cellular data plan turned off and primarily use my phone through wifi at home and work. I missed the birth announcement of my niece because of this senseless feature...

This is from the iPhone User Manual:
Messages lets you exchange text messages with other SMS and MMS devices via your cellular connection, and with other iOS devices using iMessage.
iMessage is an Apple service that lets you send unlimited messages over Wi-Fi (as well as cellular connections) to other iOS and OS X Mountain Lion users. With iMessage, you can see when other people are typing, and let them know when you’ve read their messages. iMessages are displayed on all of your iOS devices logged in to the same account, so you can start a conversation on one of your devices, and continue it on another device. iMessages are encrypted for security.
The bottom line is MMS (text messages with photos) uses your cellular service. iMessage, which uses WiFi, is used to communicate between Apple devices.
Hope this helps.

Does this setup make sense?

I have DSL from Verizon via an Actiontec GT704WG modem/router. I plan to shut off wireless and disable DHCP and NAT in that device, and connect one of its ethernet ports to the WAN port of a Time Capsule. Then the Time Capsule will be configured to provide DHCP an NAT. Other devices (Ooma for example) will then connect to the ethernet ports on the TC.
Should work, right?

I plan to shut off wireless and disable DHCP and NAT in that device, and connect one of its ethernet ports to the WAN port of a Time Capsule.
Shutting off wireless and disabling DHCP and NAT will not likely make the Actiontec a simple bridge mode modem.
Check with Actiontec support to ask them how (and if) it is possible to configure the Actiontec as a simple bridge mode modem.

When does someone actually make an effort to resolve your concern ? After they suspend you?

I have been back forth with Verizon customer service, tech support and executive offices regarding my concern. NOTHING has been resolved. My service is suspended due to a past due balance I refuse to pay as all the fees have not been removed from my account as promised. Now my only response from executive offices is " work something out with financial services" Is this a joke?

Aside from kernel, initscripts/other core utilities, and/or possibly video driver updates, I've seen no need to reboot after updating; daemons and such can be restarted to start the new version.

Does my DNG/RAW workflow make sense to you?

Ive been shooting RAW from my Nikon D50, converting the files to DNG (3.3), opening them in Adobe Camera RAW (2.4) using PSCS, processing and saving in TIFF (often through a droplet). In the process I retain the original RAW .NEF file, create a universal DNG file, and finally create a lossless TIFF file.
I do things this way because I want the supposedly more universal format of DNG, and Camera RAW 2.4 (which runs on CS) doesnt officially support the D50 .NEF file.
I cant think of a reason to upgrade either the DNG converter or Camera RAW files. It appears that the new versions basically just support new cameras. Besides, to do so Id have to upgrade to CS3, and thats totally out of the question.
I take about 2,500-3,000 shots a year not counting the ones I take for experimenting with different settings and such. I know some folk might think my process is time consuming and/or overkill to create and retain DNGs AND TIFFs, but Im thinking it just makes sense. Does this workflow make sense to anyone other than myself?
Im going to post this in both the RAW and DNF forums to see who thinks what. Thanks for your opinions!

Ive been hanging around the forums for a couple years now and have learned quite a bit from the others. Perhaps Ive helped others in the meantime. Im thinking thats the intent of the forum. Ive seen people blasted for not being as knowledgeable as some of the others and Ive always thought it's a shame. However, it appears Ive accidentally irritated folk by asking an opinion of something.
I mentioned in the OP that I'll not be upgrading to CS3 or any other version of PS. So by default, and a point not picked up by some- the question is really in regard to the newer version of DNG and NOT Camera RAW.
When I looked at the download page it appeared that the new version of DNG might somehow be connected to RAW. After all, they are in the same .ZIP file. Mr. Knoll was kind enough to point out that the newest version of DNG didnt require a PS upgrade. I should have figured that out myself as its a stand alone program, but by the way it was packaged Anyway, I downloaded the file, and unzipped it. Then ran DNG.
It works fine. Just as the previous version. But what I was asking, and what some people took issue with, was if there were features that had been faulty with previous version, or perhaps previous versions did work with RAW formats from certain cameras. Things like that.
I was thinking Mr. Knoll or another knowledgeable person might respond with Sure, Thomas, the newer version of DNG processes batch files much faster due to an improved bit-handling algorithm or Naw, the newer version of DNG is just compatible with more camera formats, so if the version you have works, no need to upgrade, or maybe even The newer version fixes a few minor issues with converting files over 9 MB in size.
Instead, I was told that I wouldn't be asking such a preposterous, absurd question. if I had read the linked article. Well, prior to my second post, I did read it read it. Its a nicely written article with some great shots of the interface. It touts the new RAW as the best there is, and according to the author, Jeff Schewe, its well worth the price. But I also noticed it said nothing of the new version of DNG. Maybe thats because the article is titled About Camera RAW 4.1.
Thank you, Mr. Knoll and G Sch.

Does iPhone as tethering device make sense?

Why pay to use the iPhone as a tethering device instead of just using the iPhone itself? People using iPhone to tether their iPad in particular doesn't make much sense to me since they pretty much have the same function (one just has a bigger screen).
Does it really make sense to pay another $25 a month to tether the iPad to the iPhone when you can just use the iPhone to do what you need done? I'm asking because it would be nice I guess, but can someone really make a good case for the extra money spent for this?

Does this VoIP strategy make sense?

I have a VoIP gateway that is marking packets with DiffServ CS1 and CS2 levels. These packets first hit an internal router that has a GRE/IPSec transport mode tunnel to another router on the public Internet. The internal router uses its FastEthernet port to connect to a second in-house router that has a T1 connection to the Internet. In order to setup some QoS I would like do the following:
1) On the internal router I am not going to setup any actual QoS policies but I want to use the "qos pre-classify" commands on the crypto map and the tunnel interface in order preserve the DCSP info on the IPSec encrypted packets that will be processed by the Internet router
2) On the Internet router I will setup a policy that matches DCSP packets and assigns them to a LLQ using the "priority" command.
Since the IPSec tunnel also carries non-VoIP traffic my objective here is to prioritize only IPSec packets that have voice. Non-voice IPSec and all other traffic will be treated in best-effort mode.
Does my plan make sense?
Thanks,
Diego

Since IOS 11.3T, the TOS bits of the IP header is copied automatically to the TOS bits of the GRE header. However, there was a problem. While the subsequent routers could use this info in the TOS field of the GRE header, the router doing this initial copying itself was unable to prioritize based on the TOS bits. The 'qos pre-classify' command solves this problem. With the command configured, the packets will be correctly classified and the qos policy applied on the headend router too.
The information ultimately copied into the TOS bit of the new header, mirrors the TOS bit in the original header. Also, the TOS bit is copied regardless of the 'qos pre-classify' command.

Does an "incomplete font" warning make sense for ttf?

Hi all,
we are getting "font incomplete" errors in the package dialog. According to the online help this "Lists fonts that have a screen font on the current computer but not a corresponding printer font."
Does that even make sense for true types? As far as I know there is no such thing as a separate screen and printer font in ttf.
To make things worse the fonts in question are Georgia and Times New Roman - both are system fonts.
Specs:
Windows 7 64 bit SP1
InDesign 7.04
I can't reproduce this on my machine but that's running 32 bit.
Should we ignore it?
Any hints appreciated - tried a forum search but didn't find very much.
Regards,
Mike

There is no real erro message but a warning in the package dialog (sorry but we are using the German version):
The report doesn't offer much more information:

We actually don't even know where TimesNewRoman comes from - I suspect it's in one of the numerous linked pdf files. But then the dialog should state which files they come from.

Color Space and Bit Depth - What Makes Sense?

I'm constantly confused about which color space and bit depth to choose for various things.
Examples:
- Does it make any sense to choose sRGB and 16-bits? (I thought sRGB was 8-bit by nature, no?)
- Likewise for AdobeRGB - are the upper 8-bits empty if you use 16-bits?
- What is the relationship between Nikon AdobeWide RGB, and AdobeRGB? - if a software supports one, will it support the other?
- ProPhoto/8-bits - is there ever a reason?...
I could go on, but I think you get the idea...
Any help?
Rob

So, it does not really make sense to use ProPhoto/8 for output (or for anything else I guess(?)), even if its supported, since it is optimized for an extended gamut, and if your output device does not encompass the gamut, then you've lost something since your bits will be spread thinner in the "most important" colors.
Correct, you do not want to do prophotoRGB 8bit anything. It is very easy to get posterization with it. Coincidentally, if you print from Lightroom and let the driver manage and do not check 16-bit output, Lightroom outputs prophotoRGB 8bits to the driver. This is rather annoying as it is very easy to get posterizaed prints this way.
It seems that AdobeRGB has been optimized more for "important" colors and so if you have to scrunch down into an 8-bit jpeg, then its the best choice if supported - same would hold true for an 8-bit tif I would think (?)
Correct on both counts. If there is color management and you go 8 bits adobeRGB is a good choice. This is only really true for print targets though as adobeRGB encompasses more of a typical CMYK gamut than sRGB. For display targets such as the web you will be better off always using sRGB as 99% of displays are closer to that and so you don't gain anything. Also, 80% of web browsers is still not color managed.
On a theoretical note: I still don't understand why if image data is 12 or 14 bits and the image format uses 16 bits, why there has to be a boundary drawn around the gamut representation. But for practical purposes, maybe it doesn't really matter.
Do realitze hat the original image in 12 to 14 bits is in linear gamma as that is how the sensor reacts to light. However formats for display are always gamma corrected for efficiency, because the human eye reacts non-linearly to light and because typical displays have a gamma powerlaw response of brightness/darkness. Lightroom internally uses a 16-bit linear space. This is more bits than the 12 or 14 bits simply to avoid aliasing errors and other numeric errors. Similarly the working space is chosen larger than the gamut cameras can capture in order to have some overhead that allows for flexibility and avoids blowing out in intermediary stages of the processing pipeline. You have to choose something and so prophotoRGB, one of the widest RGB spaces out there is used. This is explained quite well here.
- Is there any reason not to standardize 8-bit tif or jpg files on AdobeRGB and leave sRGB for the rare cases when legacy support is more important than color integrity?
Actually legacy issues are rampant. Even now, color management is very spotty, even in shops oriented towards professionals. Also, arguably the largest destination for digital file output, the web, is almost not color managed. sRGB remains king unfortunately. It could be so much better if everybody used Safari or Firefox, but that clearly is not the case yet.
- And standardize 16 bit formats on the widest gamut supported by whatever you're doing with it? - ProPhoto for editing, and maybe whatever gamut is recommended by other software or hardware vendors for special purposes...
Yes, if you go 16 bits, there is no point not doing prophotoRGB.
Personally, all my web photos are presented through Flash, which supports AdobeRGB even if the browser proper does not. So I don't have legacy browsers to worry about myself.
Flash only supports non-sRGB images if you have enabled it yourself. NONE of the included flash templates in Lightroom for example enable it.
that IE was the last browser to be upgraded for colorspace support (ie9)
AFAIK (I don't do windows, so I have not tested IE9 myself), IE 9 still is not color managed. The only thing it does is when it encounters a jpeg with a ICC profile different than sRGB is translate it to sRGB and send that to the monitor without using the monitor profile. That is not color management at all. It is rather useless and completely contrary to what Microsoft themselves said many years ago well behaved browsers should do. It is also contrary to all of Windows 7 included utilities for image display. Really weird! Wide gamut displays are becoming more and more prevalent and this is backwards. Even if IE9 does this halfassed color transform, you can still not standardize on adobeRGB as it will take years for IE versions to really switch over. Many people still use IE6 and only recently has my website's access switched over to mostly IE8. Don't hold your breath for this.
Amazingly, in 2010, the only correctly color managed browser on windows is still Safari as Firefox doesn't support v4 icc monitor profiles and IE9 doesn't color manage at all except for translating between spaces to sRGB which is not very useful. Chrome can be made to color manage on windows apparently with a command line switch. On Macs the situation is better since Safari, Chrome (only correctly on 10.6) and Firefox (only with v2 ICC monitor profiles) all color manage. However, on mobile platforms, not a single browser color manages!

I need to work on documents in both my iMac and air book. But I have to download document and them upload it, and when I upload it I can't open it unless I open it on my phone first. Yet changes made on phone appear straight away. Does this make sense????

On your Macs open System Preferences > iCloud
Deselect the box next to Documents & Data, then reselect that box then restart your Macs.
On the iPhone tap Settings > iCloud. Switch Documents & Data off then back on then reset the iPhone.
Hold the On/Off Sleep/Wake button and the Home button down at the same time for at least ten seconds, until the Apple logo appears.
See if you can open the files now without opening on the iPhone first.
