Does it harm the battery to leave the MacBook pluged in all of the time?
Does it harm the battery to leave the MacBook pluged in all of the time?
It is OK to leave your battery hooked to the charger most of the time. The only time I unhook mine from the charger is when I calibrate. You should calibrate your battery once a month. This keeps your battery healthy for when you need to use your MacBook portable.

No. Charging automatically stops when the battery reaches capacity.

DATE type returned from function does not return the time component
Hi,
I'm dealing with a strange problem. I have a PL/SQL function (running on Oracle 8.1.4.7) which returns a DATE value. Like we all know the DATE datatype includes a date component and a time component.
The function I used for testing is like this:
FUNCTION ReturnDate return Date is
dReturn Date;
Begin
select sysdate into dReturn from dual;
return dReturn;
end ReturnDate;
When I call this function from .NET using ODP.NET the date value I get does not have the time component included only the day-month-year components.
This is a code-snippet that calls the function :
command.CommandText="Schema.ReturnDate";
command.CommandType=CommandType.StoredProcedure;
command.Parameters.Add("Return_Value",
OracleDbType.Date,0,ParameterDirection.ReturnValue);
command.ExecuteNonQuery();
I use the OracleDbType.Date type which I think is the most logical choice, because the type in the Database is after all DATE.
However this does not include the time componet. But if I change the OracleDbType.Date to OracleDbType.TimeStamp I get the time component. I'm not happy with this "hack" because I'm not sure what will happen when we upgrade our version of the Database to Oracle 9i which uses the new TimeStamp datatype.
Is this a bug that the OracleDbType.Date does not include the time component??How do you examine the output Date value?
If it is from the string, then the time components will
not show because the NLS_DATE format in the client
machine does not contain the time components.
In American, the Date format is 'DD-MON-RR' by default whereas, the TimeStamp format is 'DD-MON-RR HH.MI.SSXFF AM' by default.
Can you take a look at the time components from the OracleDate by accessing the time properties, eg. OracleDate.Hour, OracleDate.Minute..etc to see if the time values are there?
Thanks

Use of external battery cases, does it harm the iphone's internal battery?
Can the use of external battery cases harm the life of the internal battery in the iphone 4? (ie. Mophie juice pack air)
Absolutely not, but if looking for a protective case i would not recommend the mophie but if just using your phone for commercial use, then yes definitely use, it's helpful when you need a cordless charger

Does it harm the battery if the macbook stays turned off for a few months?
I might be in a situation where I will not use my macbook for a few months. A family member may use it occasionally, but it would be turned off most of the time. Does this hurt the battery or other aspects of computer performance?
From the User Manual: "Storing your MacBook If you are going to store your MacBook for an extended period of time, keep it in a cool location (ideally, 71° F or 22° C) and discharge the battery to 50 percent. When storing your computer for longer than five months, discharge the battery to approximately 50 percent and then remove it from your MacBook. To maintain the capacity of the battery, recharge the battery to 50 percent every six months or so."

The battery indicator in mountain lion does not show the time left!
I have updated to Mountain Lion today and i noticed that the battery indicator on the top bar only show percentage of the battery, and it don't have the option to show the time left for recharge or to the total discharge of the battery.
The only way to show the time left is to clic on the meter itself.
Any ideas?I'm going to submit a complaint via http://www.apple.com/feedback/macosx.html. I hope others do the same.

Why does iCal change the time of my events when I import my schedule? PLEASE HELP
When importing my schedule (from my school website, week by week), I had no problem in September. Now, something must be screwed up in my iCal, because the same documents are importing 3-4 hours behind my current time zone (Atlantic). Atlantic time is specified in the files, so it isn't that. This happens in the guest user as well.
I turned off time zone support (I feel as though this is what made it stop working, as the default was off and I turned it on around the time it stopped working). It still doesnt work even with time zone turned off and the time on my computer is set manually (instead of automatically detecting it). Also, I tried to find the preference file in my library>preferences, but it didn't exact... not one single com.apple.ical plist file in there!!! It seems to work fine from my iphone EXCEPT it creates 2 events for each single event (at the same time) which is rather annoying.
Anyone know/have any ideas on how to fix this??Yeah that was it, I realised straight afterwards (I'm just impatient lol). Thanks anyway

Where does iPhoto save the time for each photo?
I copied some photos from the library to my desktop, ran software to add an hour to several at once (forgot daylight savings time), deleted the original photos from iPhoto, and re-imported the new copy with the new times back into the library.
I was very surprised to see the information window on the bottom left side of the iPhoto window still showed the old time. Even more confusing is that if I bring up the main info window (CMD-I), the time indicated there is the time I corrected to.
Why do these times not match? Where is iPhoto keeping the old times?Bob:
Other users have reported that also. I've used PhotoInfo to change time and dates of file and upon importing back into iPhoto they are reported as changed in both the Source window info section and in the Get Info window's Photo section. Don't know why I can do it and the other users were not able to.
I just dragged the photos from the thumbnail window to the desktop, launched PhotoInfo, went to the File->Open menu and select the file. I then changed the time and clicked on Change button. Upon importing into iPhoto the date displayed as changed. If you didn't use PhotoInfo you might give it a try. -
If I try to enter any number with a colon, Calendar assumes, that's the time for the event. Not sure why this change was made. I need to enter a time in the subject line, and a different time for the event to happen. Old version allowed this with no problem. What do I need to do in Mavericks to allow this.???
Many thanks in advance for any solutions.
Ned C:Hi,
I have a small application called Multi Event Filter available on the Mac App Store which creates Calendar events from text or spreadsheets. While not really what it was designed to do, a side effect of Multi Effect Filter is that it retains the times entered for events in the titles.
You can find more ablout Multi Event Filter here.

hi all ,
declare
mydate date ;
begin
mydate := sysdate ;
dbms_output.put_line(mydate);
end;
i have an existing script that looks like above except it writes into a table e.g tbl1 , Field1
what i dun understand is the output shown is : 31-JUL-06
but why it comes with the time when i select * from tbl1 ? e.g 7/31/2006 3:01:01 AM
how come the date format is different as i do not see any to_char(sysdate , date_format_expression) ??
is this something defulted by Oracle ?
tks & rdgs---See the difference:
SQL> declare
2 mydate date ;
3 begin
4 mydate := sysdate ;
5 dbms_output.put_line(mydate);

Thread CPU time: does it include the time while thread is waiting
Hi,
My question is regarding the getCurrentThreadCpuTime() supported by the ThreadMXBean.
I wonder if the returned time includes the time while the thread is waiting, i.e. after the thread calls wait() and before getting a notify() or a notifyAll().
Thanks,
NuhaCPU time is intended to reflect actual time executing on a CPU. If block for a lock/wait/sleep or other blocking operation like I/O then you don't consume CPU while blocked.
On Solaris it is implemented using gethrvtime()
If a VM used a busy-wait for something rather than blocking (not likely with wait()) then that's consuming CPU time. -
Does it harm the battery if we use the laptop while charging?
If we use while charging, is the power required directly taken from the external supply or from the battery itself. Which is the safest way to use the laptop without drawing power from the battery?
No harm is done. There is enough power from the adapter to run the laptop and charge the battery. There is hardware and software in place which prevents any problems. The laptop will not take power from the battery while the AC adapter is plugged in.

Does it harm the HD if you move the laptop while it's on?
My MacBook's hard drive had crashed a couple months ago and we took it to Apple so they could replace the hard drive. We asked why this happened suddenly and the support person told us that the top two reasons hard drives crash are over heating (on a bed) and being move while the laptop is on. Aren't MacBooks supposed to be moveable? I didn't think the point of laptops were for them to remain steady and not move, isn't that what a desktop is for?
Could this really be the reason my HD crashed and had to be replaced? Should I just not move my laptop in the future, because that seems to defeat the purpose of one.
*Moving as in picking it up and going to another room with it on not like being rough with it and banging it into walls.If you move your portable (any portable) computer while the hard drive is whizzing around at 5,000 rpm plus with a teeny little read device a couple of thousandths of an inch away there is obviously potential for damage, generally the 'sudden motion sensor' will intervene and attempt to stop damage from occuring but the safest way is not to move it under those circumstances.
