Greens from my Nikon D800 are way over saturated and too bluish 14 bit NEF

Greens from my Nikon D800 are way over saturated and too bluish 14 bit NEF uncompressed files. I have no problem with raw files from other cameras is there a setting I am missing somewhere?

Hi,
I have been shooting my D800 for over a year now, and I have not observed what you are discussing, particularly in outdoor, natural light situations.
I have downloaded your NEF, and imported it into Aperture (3.4.5). I notice two things right away: 1) you are using Uncompressed NEF, 14 bit recording; and 2) you seem to have a custom White Balance. The former should be of no matter, but would be interested if you have been able to discern any advantage over Lossless Compression, 14 bit?
However, the important concern is with the Custom White Balance impact on the rendering of NEFs in RAW in Aperture. I am planning to do a study of this, and am wondering if you could test your resutls in similar shots with Auto White Balance rather than any preset (yours or the camera standard presets)?
I by practice only shoot Auto White Balance (and RAW), but recently I have found benefit to using a preset WB when shooting video since that result will not be modifiable later on the computer. After doing this, I have sometimes forgotten to reset the WB to Auto before again shooting stills in RAW, and the resulting difference vs once reset has been curious.
While it is well known that Picture Controls when used and shooting RAW will likely result in wide differences between the Camera Preview and Aperture's first rendering, I am less certain what the dynamics of White Balance settings and first rendering in Aperture.
Thanks for the test image and chance to discuss this.

What do you mean by 'frozen' ? Have you tried a soft-reset to see if that gets it to work ? Press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider if it appears), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

My hp compaq presario62 has been over heating and mostly shut down what can i do

my hp compaq presario62 has been over heating and mostly shut down what can i do?

You can try a usb cooling pad but I am not a big fan of them....if your laptop needs one there is a problem that needs to be fixed. The likely issue is a clogged fan and cooling system which requires disassembly and cleaning out around the fan and heatsink, removing the heatsink and appplying new thermal compound. You can also perhaps help by using compressed air blown into the heat vents.

SCRIPT5007: Unable to get property 'top' of undefined or null and too much recursion

I am not sure about placing two questions into one post, but here it goes:
The error above "SCRIPT5007: Unable to get property 'top' of undefined or null" is coming from this function:
Code:
$(function () { //this is the way to run your code at the DOM Ready event $('a').click(function () { $('html, body').animate({ scrollTop: $($(this).attr('href')).offset().top }, 1500); return false; }); });
This is the effected code I believe that is causing the problem:
Code:
scrollTop: $($(this).attr('href')).offset().top
the error occurs when I click on a "clear" button in my form. My website is one long page and that function allows my navigation to slide up and down the site. Without it, everytime you click a nav, it jumps to that anchor.
For the 2nd problem, the too much recursion, the problem lies within here:
Code:
function () { if ($.isReady) return; imReady = true; $.each($.includeStates, function (url, state) { if (!state) return imReady = false }); if (imReady) { $.readyOld.apply($, arguments) } else { setTimeout(arguments.callee, 10) } }
where the error is actually coming from the 2nd "function" script. This is part of the browser compatibility script for mozilla/opera at the top of the index page. Any help would be great. Thanks.

Ahh I apologize. I simply was posting to JavaScript forums in hopes of
finding a solution. Sorry for the mixup.

SL440 Over Heat and Wireless disconnect

Hi
I have a problem with Thinkpad sl440. I get these types of problem not a single laptop but also any of them.
First problem is over heat I measured overheat of the HDD by crystal disk info After one or two hours left its temp goes to 50°c.
Second one is wireless Lan Disconnect after few hours later the wireless disconnect automatically and it also doesn't show any wifi signal in his range. But after restarting the wireless lan work again. After that it goes to disconnect again after few hours.
I hope this problem occurs from over heat from the motherboard..
Please give me a solution.

HT4061 I got a brand new iPhone 4S on contract last week and since I've had it it's been over heating and it's turned itself off once and every now and then the screen flickers I just wanted to know is this a common thing as I've never had an iPhone befor

My new iPhone 4S that I have had a for about a week keeps over heating a lot and its turned itself off once and I couldn't turn it on for over half an hour,also my screen flickers from time to time and I'm not sure what to do as I not had an iPhone before can anybody help me please I would be very greatful.

No, it's not normal.
Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new).
Frankly though, considering it's new, take it back to Apple.

My iphone 4 is over heating and it overheated then shutoff and now it wont charge what should i do?

please help me it stopped over heating along time ago then started back up again. but now its not charging.:( even when its off it still overheats.

SpamAssassin and too much CPU load

I have been testing my messaging server and SpamAssassin integration. Everything seems fine except too much CPU load coming from spamd (SpamAssassin's daemon). I am testing them on a UltraSparcII-i, 256MB, Solaris 10 box. When I loaded it with 4msg/min containing 50K ascii text each on the receiving side, the spamd process went up to 90% of CPU load, and then just died silently. My questions;
1) Is there any performance tuning that I should do to avoid that much CPU load? Or is this just normal?
2) I have heard of another anti-spam product called dspam. How can I integrate dspam with the Java Messaging Server?
Thanks!

Installation of JES Messaging Server by itself suggests 1.2 gig of RAM. SpamAssassin adds to that suggestion.
You have less than 1/4 of the suggested RAM. You're 'way short.
SpamAssassin will use cpu. I found that nx x86 box was far less expensive to feed, and works extremely well for Messaging and SpamAssassin. 1 gig or ram for my PC costs about $75. Adding ram to your Sparc will cost mor than a PC complete.
4 messages/min isn't much, but. . .
You're likely swapping pretty hard. Check for "I/O wait". I often use "top" for a quick look at such.
When I switched from an "ultra-5" with 384 megs ram, to an AMD 1200+ with 1 gig of ram, my system went from feeling totally buried to feeling mostly un-used. I'm currently able to handle far more than 4 message/minute, with no overload or swapping.

White pixels and too much contrast on new touch

hi all!
i got a new touch today. i allready have one but this one i won in a contest. anyway, when after having synced over alot of content i started noticing som strange things about the screen. first of all, some colors looks washed out and too bright. it has nothing to do with the settings since i allways had my old one on full brightness and it never looked like this.
then i when i looked closer at the screen i saw alot of white pixels that disapeared and apeared depending on how i hold the touch. here is a pic of the pixels (note that the screen is not this bright, my cam just made it like that for some reason):
http://img182.imageshack.us/img182/8443/shiiiit012copyqv1.png
so is this what people call dead pixels? would i get a new touch if i send it to apple you think? or are there anything els i could do? we dont have any official apple stores where i live. thanks alot in advance!

Did you get this problem fixed? I have only had my ipod touch for about 30 days and it too lost it's contrast. It now looks white washed, with little contrast. There is no true black, white or gray, and the colors seemed washed out. I am considering simply taking it in for repair. What did you do? Thanks for any information you can provide.

My battery life is running out really fast and my computer heats up too much what should I do?

I have a year old Mac Book Pro Retina 13' and the battery runs out way too fast and the life is not as much as it was a few days ago. As well it started 'breathing' heavily and heating up very fast and very heated. What should I do? What has happened to my computer?

Has anyone else had any problems with their phone over heating and shutting down?

I've had my phone for less a month and I've already had issues with my iphone 4. On several occassions it has overheated and shut down. On one occasion I put the phone in the side pocket of my purse where, I also had a charger for my camera. When I removed the phone, it was hot...not warm but hot! On another occasion I was at the movies and put the phone face down on my lap, at one point i touched the phone and again it was hot. When the movie was over, and I looked at the phone it had shut down....this has happened a few times more since then. I've also had problems with the phone shutting down on it's own. I took it to my local apple store and the representative looked at my phone and ran a diagnostic check for me. He said the everything on my phone looked normal and that my phone probably needs a "breaking in" period...to give it a couple of months...He really didn't tell me much more...I don't use my phone for more than the basics...calling, texting, and some mild app use...I don't understand how I can be having these problems when I've had my phone for less than a month...The rep tried selling my the Apple insurance. He told me that through ATT I only have 30 days, and I would be better off getting this insurance. I feel very dissastisfied with the service I got. I was done with my appointment within 10 mins, I don't think the representative took the time to listen to my concerns.

Thanks for your reply, but I guess whether this was a silly question is a matter of opinion. That is the whole purpose having these forums...so that people can post their questions, silly or not. Maybe you are an Apple expert or have "techy" knowledge, but I don't. So what may be silly or stupid for you, can be completely different for a novice apple consumer like me. If you must know, I did do my research, and I did do the basic trouble shooting.All to no avail. I took my phone to the apple store, had it diagnosed and was told some very inaccurate information. I ended up going back today, and got a second opinion. This person actually took the time to talk to me and to better explain Applecare and my warranty. She also told me that there is no such thing as a "break in" period, and when there is a shutting down issue, even after a "restore" that it was better to get it replaced. Which is what she did. She replaced my phone. Obviously, the first person, by his own admission, was too tired and ready to go home to actually take the time to explain and offer other options...

Fill Factor and Too Much Space Used

Okay, I am on sql server 2012 sp2. I am doing a simple update on some large tables where there is an int column that allows nulls and I am changing the null values to be equal to the values in another integer column in the same table. (Please
don't ask why I am doing dup data as that is a long story!)
So it's a very simple update and these tables are about 65 million rows I believe and so you can calculate how much space it should increase by. Basically, it should increase by 8 bytes * 65 million = ~500Mbytes, right?
However, when I run these updates the space increases by about 3 G per table. What would cause this behavior?
Also, the fill factor on the server is 90% and this column is not in the PK or any of the 7 nonclustered indexes. The table is used in horizonal partitioning but it is not part of the constraint.
Any help is much appreciated...

Hi CLM,
some information to the INT data type before going into detail of the "update process":
an INT datatype is 4 bytes not 8!
an INT datatype is a fixed length data type
Unfortunatley we don't know anything about the table structure (colums, indexes) but based on your observation I presume a table with multiple indexes. Furthermore I presume a nonclustered non unique index on the column you are updating.
To understand why an update of an INT attribute doesn't affect the space of the table itself you need to know a few things about the record structure. The first 4 bytes of a record header describe the structure and the type of the record! Please take the
following table structure (it is a HEAP) as an example for my ongoing descriptions:
CREATE TABLE dbo.demo
Id INT NOT NULL IDENTITY (1, 1),
c1 INT NULL,
c2 CHAR(100) NOT NULL DEFAULT ('just a filler')
The table is a HEAP with no indexes and the column [c1] is NULLable. After 10,000 records have been added to the table...
SET NOCOUNT ON;
GO
INSERT INTO dbo.demo WITH (TABLOCK) DEFAULT VALUES
GO 10000
... the record structure for the first record looks like the following. I will first evaluate the position of the record and than create an output with DBCC PAGE
SELECT pc.*, d.Id, d.c1
FROM dbo.demo AS d CROSS APPLY sys.fn_PhysLocCracker(%%physloc%%) AS pc
WHERE d.Id = 1;
In my example the first record allocates the page 168. To examine this page you can use DBCC PAGE but keep in mind that it isn't documented. You have to enable the output of DBCC PAGE by usage of DBCC TRACEON with the TF 3604.
DBCC TRACEON (3604);
DBCC PAGE (demo_db, 1, 168, 1);
The output of the above command shows all data records which are allocated on the page 168. The next output represents the first record:
Slot 0, Offset 0x60, Length 115, DumpStyle BYTE
Record Type = PRIMARY_RECORD Record Attributes = NULL_BITMAP Record Size = 115
The above output shows the record header which describes the type of record and it gives some information about the structure of the record. It is a PRIMARY RECORD which contains NULLable columns. The length of the record is 115 bytes.
The next ouptput shows the first bytes of the record and its logical solution:
10 00 PRIMARY RECORD and NULLable columns
70 00 OFFSET for information about number of columns (112)
01 00 00 00 Value of ID
00 00 00 00 Value of C1
6a757374 Value (begin) of C2
If might be complicate but you will get a very good explanation about the record structures in the the Book "SQL Server Internals" from Kalen Delaney.
The first two bytes (0x1000 describe the record type and its structure. Bytes 3 and 4 define the offset in the record where the information about the number of columns can be picked up. As you may see from the value it is "far far" near the end of the record.
The reason is quite simple - these information are stored BEHIND the fixed length data of a record. As you can see from the above "code" the position is 112. 112 - 4 bytes for the record header is 108. Id = 4 + C1 = 4 + C2 = 100 = ??? All the columns are FIXED
length columns so is it with C1 because it has a fixed length data size!
The next 4 bytes represent the value which is stored in Id (0x01000000) which is 1. C1 is filled with placeholders for a possible value. If we update it with a new value the preallocated space in the record structure will be filled and NO extra space will
be used. So - based on the simple table structure - a growth WILL NOT OCCUR!
Based on the given finding the question is WHAT will cause additional allocation of space?
It can only be nonclustered indexes. Let's assume we have an index on c1 (which is full of NULL). If you update the table with values the NCI will be updated, too. For each update from NULL to Value a new record will be added to the NCI. What is the size
of the new record in the NCI?
We have the record header which is 4 bytes. If the table is a heap we have to deal with a RID it is 8 bytes. If your table is a Clustered index the size depends on the size of the Clustered Key(s). If it is only an INT it is 4 bytes. In the given example
I have to add 8 Bytes because it is a HEAP!
On top of the - now 12 bytes - we have to add the size of the column itself which is 4 bytes. Last but not least additional space will be allocated if the index isn't unique (+4 bytes) allows NULL, ...
In the given example a nonlclustered index will consume 4 bytes for the header + 8 bytes for the RID + 4 bytes for C1 + 4 bytes if the index isn't unique + 2 bytes for the NULLable information! = 22 bytes!!!
Now calculate the size by your number of records. And next ... - add the calculated size for EACH additional record and don't forget page splits, too! If the values for the index are not contigious you will have hundreds of page splits when the data will
be added to the index(es) :). In this case the fill factor is worthless because of the huge amount of data...

Structure of a record:
http://www.sqlskills.com/blogs/paul/inside-the-storage-engine-anatomy-of-a-record/
PS: I remember my first international speaker engagement which was in 2013 in Stockholm (Erland may remember it!). I was talking about the internal structures of the database engine as a starting point for my "INSERT / UPDTAE / DELETE - deep dive" session.
There was one guy who asked in a quite boring manner: "For what do we need to know this nonsence?" I was stumbeling because I didn't had the right answer to this. Now I would answer that knowing about record structure and internals you can calculate in a quite
better way the future storage size :)
You can watch it here but I wouldn't recommend it :)
