Memory fault with N97 and loss of apps including d...

Hi folks,
I wonder if someone made experiences with this and found a remedy to regain lost applications especially if the tool to do so ordinarily is itself affected :-(
During a trip out of a sudden photos and videos made with the camera started to vanish as soon as they were once played or seen. Or to put it better they got corrupted. The respective photo application was still working fine with a memory chip, but not with the mass memory. There certain file folders contained rubbish - a hotchpotch of signs instead of somewhat sensible names. Among those affected folders where E:/Images/camera/... and E:/data there with j2me, Others and temp...
I could do nothing as any attempt to work on or remove those files was leading to a general failure message.
Some apps got lost, yet could partly be reinstalled by download! and OVI Store, which was cool as I was abroad for quite some time and could thus recover some workable status.
At home I reconnected the device to my Vista PC and after some initial failures I got a error repaired message when switching to the USB mass storage option. After this the system was cleared yet I lost any operation of download! which is despite the OVI store still of importance to load general tools and language and speech tools which I use frequently. Pressingthe referenced button simply gives a short flicker on the screen and that was it - no starting up of the application.
I have the latest firmware for my build 11.0.021 and yet tried as well a reinstall with the nokia software updater - in vain.
As I have a number of licensed software which I can only partly reinstall without new costs - Nokia please create a full backup tool securing all components as Ghost and Co. would do with any harddisk - I am keen on a minimal invasive solution.
I have not tried formatting as I dislike to loose the licenses and I will probably have to get the whole newly bought device exchanged, but this will lose any programs not registerable to a new IMEI.
So I prior to doing something unrecoverable I would appreciate any good ideas and hints.
Can you help me?

Well, after performing a little more research, I think I know why this occurred. When the iphone crashed due to an app being updated via iTunes (I think it was NowPlaying), the Texas Holdem app was not selected in the sync applications tab upon reboot. When the iphone rebooted, I didn't check the applications tab and just re-synced. That caused the Texas Holdem app to be deleted from the iphone (and all the statistics as well). After playing a few games last night and then upgrading to version 1.1, my statistics were still saved.
So, this probably won't affect everyone but be careful when you sync to upgrade any app and make sure the app is selected in the applications tab first. It would probably help to also make a backup before upgrading any app and sync up iTunes with the iphone. This doesn't help me much but hopefully it will help someone else. Hopefully Apple will fix this issue very soon as updating any app shouldn't be this difficult.

Internal Microphone not working with Quicktime and some other apps, yet it does for Skype.

Internal Microphone not working with Quicktime and some other apps, yet it does for Skype.
Microphone works fine with Quictime on another mac, so I do know how to use it. The one where it is not working (A) had an external microphone and camera attached earlier, and indeed it does work with that external microphone, but not with the internal microphone selected; and (B) had RealPlayer installed previously.
Any suggestions, please?

Hi,
Download Audio driver from here.
Intructions how to install it in Vista/Win7.
Extract this driver with Winrar.
Open Device manager and expand the Sound, video and game controllers section.
Right click on Either the High Definition Audio Device if you have the generic Microsoft drivers, or the Conexant High Definition SmartAudio 221 if you have older Conexant drivers and choose "Update Driver Software..."
Click Browse my computer for driver software, then click "Let me pick from a list of device drivers on my computer"
Click "Have Disk..." then Browse to the folder where the drivers were extracted .......\V64 for 64-bit Vista/Win7. Click OK.
Select one of the "Conexant High Definition SmartAudio 221" models in the list, there will be multiple identical entries.
Click Next, and you're done.
I'm not sure which one from the list will work for You.
This drivers weren't test. So if You will try them and it will work for You let us now about.

Weird issue with spacebar and text based apps...

I've never seen this one before and I've been using OS X since the beginning.
I'm seeing this on my boss' computer so here goes...
When using any text based app ie Text Edit, Mail, Microsoft Office 2011, etc. if I try and write a word and then add a few spaces in between that and a new word the app won't let me add more than 2 spaces. If I create another user and try with the said apps there -- adding more than 2 spaces works fine. The thing is my boss doesn't really want to transition to another user because it would take him forever. Thus far, I've repaired permissions and deleted a few suspect preferences. Nothing worked. Any ideas as to why this is happening. Could there be some hidden setting that is user wide that would cause this?
Regards,
Scotty

Moving all the prefs to a folder on the desktop seemed to work. I figured that Mail would be important along with a few other apps like Address Book and iCal so I left them in the Preferences folder. The boss is going to have to deal with any other loss of preferences.
Thanks Tom!

Query result different with profit and loss statement

Hi all,
I run query Sum(JDT1.Debit - JDT1.Credit), and then compare the query result with the profit and loss statement, and there is different.
The difference is about 0.01.
At SAP, the Decimal places is set to 2.
I already checked the data, and their amount in 2 decimal.
Do anyone know such problem and what kind of query must I use so the result can be compared with the profit and loss statement ?
Thx.

Riny,
I am glad you found the issue

In this code i m facing memory problem.
It is not refreshing the memory every time.
So plz give me proper solution.
Its urgent.
Thanks
Ranveer

Hi,
   I suppose you are trying to store some particular value in memory in one program and then retieve it in another.
If so try using EXPORT data TO MEMORY ID 'ZC1'. and IMPORT data FROM MEMORY ID 'ZC1'.
To use SET PARAMETER/GET PARAMETER the specified parameter name should be in table TPARA. Which I don't think is there in your case.
Sample Code :
Data declarations for the function codes to be transferred
DATA : v_first TYPE syucomm,
       v_second TYPE syucomm.
CONSTANTS : c_memid TYPE char10 VALUE 'ZCCBPR1'.
Move the function codes to the program varaibles
v_first = gv_bdt_fcode.
v_second = sy-ucomm.
Export the function codes to Memory ID
EXPORT v_first
       v_second TO MEMORY ID c_memid.        "ZCCBPR1 --- Here you are sending the values to memory
Then retrieve it.
Retrieve the function codes from the Memory ID
IMPORT v_first TO v_fcode_1
         v_second TO v_fcode_2
FROM MEMORY ID c_memid.                                   "ZCCBPR1
FREE MEMORY ID c_memid.                                   "ZCCBPR1
After reading the values from memory ID free them your problem should be solved.
Thanks

Memory profiling with Scout and Xcode Instruments

Hi,
We are doing some memory profiling on our app, its a rather big app with a lot of assets.
The tests are being made on a iPad Mini, iOS 6.1.3, Air 4.0(latest from labs).
With Scout I'm seeing a stable 69mb of ram and 27mb of vram, which is expected.
But with Xcode Instruments it rarely drops below 200mb..
Is there something I'm missing or is that correct? It feels like quite a big diff.
Thanks!
-Simon

Sascha - thanks for the tip! I will check this out.
User514118,
There are three good online help articles (in jdev 10.1.3) that you should take a look at:
1. Deploying ADF Applications (see Tomcat section)
2. Apache Tomcat Application Server
3. Creating a Connection to Apache Tomcat
Also, related threads on the forum include:
Validate Tomcat 5.5x JNDI Configuration? (setting up datasource)
Re: Can't see adf component on Tomcat
Re: Deploy exploded war structure on Tomcat (one way to integrate with Tomcat for development cycles)
For MySQL, I needed to copy the database driver to $Tomcat_Home/common/lib folder
For Windows, here are some of my environment vars:
CLASSPATH=C:\Program Files\jdevstudio1013\jdk\lib\tools.jar;C:\jakarta-tomcat-5.5.9\common\lib\servlet-api.jar; C:\jakarta-tomcat-5.5.9\common\lib\jsp-api.jar;
JAVA_HOME=C:\Program Files\jdevstudio1013\jdk (also include this in the Path var)

Norton reports high memory usage with firefox and it crashes often

Norton antivirus 2011 has pop up warnings reporting high memory usage from Firefox. I have been getting theem often and my computer is crashing often after those pop up warnings. Thanks

Safe mode did not help.
I have disabled ALL extensions and plug-ins, but the problem with "zig-zag" memory usage still remains (I've not tried to leave browser open for the night yet).
I think I'll do clean reinstall with completely new empty profile (without sync'ed information) to try this out. If this works, I'll start adding stuff (configuration, sync, features, etc) to see what causes the problem.

Memory Errors with NX4 and Adobe 3D

After installing the Adobe 3d trial version,I've had nothing but problems with NX4.Out of memory errors when there is plenty available.REinstalled NX4,same problems.Uninstalled adobe 3D,and the problem went away.We would like to purchase this,but not until this particular problem is solved.
Win Xp SP2
2 GB Ram
Dell Precision 370
Pentium 4
NX 4.0.0.25

are you working on big 3d models in nx4 ?(to check that, please do a right click on the windows task bar and open the task manager and check the memory used by nx4 with your 3d models loaded)- did the problem also occured with small models ?
if you memory footprint approaches the 2gb barrier, then 3d capture might be the cause ot your memory problems, to get rid of it, just open acrobat3d and go in the menu edit/preferences/3d capture and delete nx4 from your list of capturable applications.

Issue with Download and Loss of Non-ASCII Characters

I have a need to allow my user to download the contents of an HTML Region as a file. This region contains some Greek letters, i.e. non-ASCII, used with some common finance formulas.
I am able to copy the contents off this region using JavaScript without any issue.
Moreover, I can copy the contents from JavaScript into a Page Item and then render the region with PL/SQL. Again, this works without an issue.
However, when I try to download the region, the Greek letters are lost in the downloaded document. Instead they are replaced with this weird series of characters: (Î”
I've created a sample app to demonstrate this problem at apex.oracle.com:
URL: http://apex.oracle.com/pls/apex/f?p=34765:1
UID: GUEST_DEV
PWD: greeksgone
Click the button labeled "Copy HTML Via JS" and you will see the statically populated region copied into the second region.
Click the button labeled "Copy HTML Via APEX" and you will see the statically populated region copied into the third region. This is achieved by copying the HTML into a Page Item and then submitting the page. When the page returns, the value of this Page Item is then used to populate the third region. As you can see, the Greek letters are there as normal.
However, if you click the "Download HTML" button you will see the the Greek letters are not present in the resulting file.

This is what the document looks like without the required meta tag:

If I could simply add this one meta tag in, everything would work beautifully:

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<BODY>

....However, I have tried every combination I can think of in the code block but, any time that I add that meta tag, I get a *404 Page Not Found* error.
The only thing standing between what we have and what we need is getting that meta tag in the output but, I just can't seem to find a way to do this. Actually, we'd really like to have, within the head tags; the meta tag, the style and the title but, not being able to get that meta tag in is the difference between acceptable and broken. It works with the others in the body.

You appear to be confusing HTTP and HTML.
The HTTP header != HTML <tt>head</tt> element.
HTP.META( 'Content-Type', null, 'text/html; charset=utf-8' );
HTP.TITLE( ls_RiskMatrixTitle ); This generates HTML content. It does not go in the HTTP header. You should be generating an HTML <tt>head</tt> element containing this (and the <tt>style</tt> element) between <tt>HTP.HTMLOPEN</tt> and <tt> HTP.BODYOPEN</tt>.
Also note that these web toolkit methods generate really obsolete HTML, therefore I never use them (and nor does APEX these days).
Don't have time to get more into this now...

Memory leak with fieldpoint and labview

I have an application which is showing an issue of a memory leak. The application does several things, but the part that seems to be causing the trouble is related to use of Fieldpoint VIs. The application reads individual AI channels on a Fieldpoint AI-110 (10 channels, where the set of channels is measured once per second) I have attached the code related to this. The memory leak is quite large (~1.5GB in 24 hours of operation).
I am using LabView 7.1, and Fieldpoint 4.1. The parent application which uses the attached code is a stand-alone application. The operating system is Windows 2000. Fieldpoint communication occurs over a RS-232 link.
Thanks in advance,
Andy

Hi Andy,
I did not see anything fundamentally wrong with what you wrote, but there were
a few things that I think could be used to be changed. However, there
were a few things that I did modify that might make a bit of a
difference. In your application you were using sequences and a bunch of
local variables. Since LabVIEW is based upon data flow, you can control
the sequence of execution by making data dependencies and simply wiring one
thing to the next. By simply using LabVIEW the way it is meant to run I
was able to completely remove the sequence structure and also eliminate the use
of all of the local variables, all while having the exact same execution order.
It could be that the local variables were causing the memory leak that you
noticed, but I really doubt they could be the cause of such a large leak.
I really think there is probably something else going on in the application
because from what I saw from this bit of code there really is no way that it
would have such large problems. Users use the FP commands daily without
any problems, so most likely these are not the root of the problem.
Go ahead and try the modified code and see if you can implement similar local
and global variable reducing techniques throughout your application.
Hopefully that will help reduce some of the memory leaks you are seeing.
Typically the largest cause of an apparent memory leak really occurs from
building an array within a loop, so make sure you don't have any situations
where that occurs in your code either.

Memory leak with jsp and beans

The application we have created has one particular page that is designed to stay up in the browser and refresh with new information from database queries once every 60 seconds. Running with Tomcat3.2.1 and IE5.5
The problem is that the memory usage of java.exe continues to grow until the machine crashes from out of memory. It does take more than 24 hours to crash.
Things I have tried to do to track down the problem or eliminate the problem.
- I have explicitly set the scope of the beans to "page"
- I have watched the DatabaseAccess.class (the beans are all extended from this class) and put in code to watch how many instantiations of the class are made and subsequently garbage collected. This appears to be where the memory leak may reside - hundreds of instantiations from some other source than the page I am displaying.
- the top frame makes database queries for security and display of a menu system dependant upon security clearance. It does not set any time for refresh (refresh == 0). Nor does it explicitly set a scope for the beans.
- I have run a different jsp engine to see if this was directly related to Tomcat - same problem with resin2.0.0
The main jsp page that is in the bottom section of the page has the following code:
** only the relevant lines are included here
<%@ include file="../../common.jsp" %>
<%
refresh=60;
%>
<head>
<%@ include file="../../meta_head.jsp" %>
</head>
<body bgcolor="#FFFFFF" text="#003399" link="#660099" vlink="#990099" alink="#006666" leftmargin="0" topmargin="0" marginwidth="0" marginheight="0">
<%@ include file="../../access.jsp" %>
<%@ include file="../../page_title.jsp" %>
<jsp:useBean id="Line" class="jsp.Line" scope="page" />
<jsp:useBean id="Machine" class="jsp.Machine" scope="page"/>
<jsp:useBean id="Alarm_log" class="jsp.Alarm_log" scope="page"/>
contents of meta_head.jsp
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<META HTTP-EQUIV= "expires" content = "0">
<META HTTP-EQUIV="Pragma" CONTENT="no_cache">
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache" forua="true">
<META NAME="robots" content="NOINDEX,NOFOLLOW">
<%
if (refresh > 0)
%>
<meta http-equiv="Refresh" content="<%= refresh %>">
<%
If anyone has some suggestions on how to trap this memory leak, it would be terrific. Or, some other things to try to stop the instantiation of the DatabaseAccess object (perhaps setting the scope of the beans in the header to "session" or "application"?).
Thanks in advance.
Roberta

jsp:useBean tags scope declaration :
page = Create a new instance on each load.
session = Load instance from the session, if not there, create one
application = Load instance from the ServletContext, if not there, create one.
Not sure how you are populating the data variables, but make sure you are closing all ResultSet, (Prepared)Statement, and Connection objects.

Python segmentation fault with matplotlib and opencv2

Once again fellow archers, I am in need of your help.
I have a file, Test1.py, which uses cv2, pylab, and numpy.
Excluding either pylab or cv2 functions, I can make the rest of the script work, but when pylab is imported, calling cv2's imshow() function causes a "segmentation fault (core dumped)".
By the sound of it, I thought it might come from the underlying C stuff, rather than python.
So I ran it through gdb.
This is where I need help. I'm not sure how to interprete the backtrace, and I probably wouldn't know what to to if I were.
Perhaps a problem with glib or GObject?
Below are the python script in question (it a template for a school assignment), and the gdb trace.

Thank you so much!
This (ugly) workaround might have saved me from a lot of trouble with this semester's exercises.
Just to be clear, the solution is:
Import opencv
Call namedWindow
Do the rest of the imports
Do the rest of the script
Corect?
I'm hesitant to mark the thread as solved, as the problem is still very much there, this workaround just allows us to ignore it.

Hosting an ecommerce website with iMac and Mac server app

Would it be possible to run an effective small business website which includes an online store using my iMac (or Mac mini), a WYSIWYG editor, my current ISP, plus, do effective SEO, configure and employ other revenue streams in addition to my own website shopping cart feature such as google shopping and implement other revenue streams on my website like ad-sense?
I need to set-up an ecommerce site for my small business which I just bought a domain for. What I'm trying to find out is if it is better to use a web host, or, if I could use my iMac with the Apple server app (or buy the mini server) and host it myself. I don't have any programming language skills, but, I believe I am capable of doing this myself once I begin to comprehend and practice the neccasary processes to make all of this happen.

Getting the easy question out of the way: yes, an iMac running Server.app and add-on eCommerce software can do this.
Now for the tougher question: should you? You're signing on for maintaining and updating and troubleshooting and potentially site remediation and decontamination after issues or security attacks. You are also signing up for PCI compliance, if you're not working with another entity for credit-card processing. (Anything with credit card data is a target for attacks; there's money involved.)
There're the more germane aspects, too: ensuring your (static IP) network links have bandwidth, availability and latency (eg: ISP bandwidth, pingdom or other uptime checks, et al), and maintaining your servers against crashes and corruptions and hardware failures (eg: RAID, possibly redundant systems); maintaining site access against the usual sorts of outages. Software updates for OS X and for the ecommerce software and whatever other dependencies are involved, too. Regular backups are most definitely required.
Or alternatively: getting somebody to maintain this stuff for you, either hosted, or dedicated to and on your server(s) and your network links, or on your own co-lo servers.
All this in addition to running your business, and writing (good, frequently updated) content that'll draw in the search engine ranking and/or buying search keywords or whatever you're doing for advertising that'll draw in potential customers, and dealing with the finances and the rest.
Servers are somewhat different from clients, in terms of system management, too. Servers involve more than one user when they're out, and so you're not rebooting or reconfiguring them nearly as often as client systems can be modified. Servers can also tend to chew up bandwidth, if you're successful.
Key to running a business is figuring out what you don't need to do (either at all, or that you can outsource or host or whatever, or hire out for, etc), so that you can focus on what you do need to do to make the business successful... If you're just getting going and not into system administration and programming payment gateways and the rest of running a server, I'd suggest hosting the ecommerce stuff, at least to start with. Unless you want to learn how to run an ecommerce site, that is...

Memory Management with NSString and synthesized properties

I thought I understood memory management but now I'm getting some odd behavior and that's the only thing I can see that I might be doing incorrectly:
I have a synthesized NSString propery called displayText. At one point I attempt to set a label with the displayText property (label.text = [[note displayText]]). The first one works, but the second one does not:
[note setDisplayText:[[note fileName]]]; // - works
[note setDisplayText:[[self getCharacterInFileName:[[note fileName]]]]; // - does not work
And here is getCharacterInFileName:
// Given the fileName for the image, get the specific part of that fileName for the note letter
- (NSString *)getCharacterInFileName:(NSString *)fileName
NSRange range = {1,1};
NSString *characterInString = [[[NSString alloc]] initWithString:[[fileName substringWithRange:range]]];
return characterInString;
Is there some pointer mismanagement going on here that I'm missing?

Nevermind, I'm an idiot. I forgot to close an if/else block with a brace and it screwed everything up.
