Question about the Ni-DAQ function used in VB

thanks for the previous answer first!
I found that my computer has not installed the Measurement Stduio. When i wanna add module with file nidaq.bas, it shows nothing. Therefore, i download this file and nidaqcns.inc file from the web. Then i add them into VB project.
When i use the function, as i don't how to use them. I just simply copy the "AI_Change_Parameter (deviceNumber, channel, paramID, paramValue)" and see the effect. But it states that "invalid outside procedure". Thereafter, i try just input 1 instead. same statement arouse.
So, my question is how to use them, because i don't have the example.
Thank you very much

It's hard to say for sure without seeing some code, but it sounds like you might be calling the function outside of a subroutine or function. Please verify that the call to AI_Change_Parameter is in a subroutine or function and if you're still getting the error, please post the code that's causing the error. Thanks.

Question about the CSS behavior when using layer 3 sticky and sticky table

Hi everyone,
I have a question about the CSS behavior when using layer 3 sticky and sticky table is full.
If I configure layer 3 sticky and specify the inactivity timeout as below, how does the CSS
handle subsequent needed sticky requests ?
advanced-balance sticky-srcip
sticky-inact-timeout 30
CSS document says that
Note:
If you use the sticky-inact-timeout command to specify the inactivity timeout
period on a sticky connection, when the sticky table becomes full and none of
the entries have expired from the sticky table, the CSS rejects subsequent
needed sticky requests.
My question is what is the next reaction by doing the CSS if the CSS is in the
following condition:
when the sticky table becomes full and none of the entries have expired from
the sticky table, the CSS rejects subsequent needed sticky requests
Does CSS just rejects/drops subsequent needed sticky requests ?
or
Does CSS does not stick subsequence requests to particular service but CSS forward
subsequence requests with round-robin basis ? which means if the sticky table is full,
the CSS just works round-robin load balancing fashion for subsequence requests ?
Your information would be appreciated.
Best regards,

Hello,
There is a good document explaining this on Cisco web site
http://www.cisco.com/en/US/products/hw/contnetw/ps789/products_tech_note09186a0080094b4b.shtml
It depends if the sticky-inact-timeout is used or not. If not, it's FIFO (the oldest entry in the sticky table is removed). If yes, the CSS will reject the next sticky request.

A quick question about the htmldb_item.checkbox function

I know many posts about checkbox have been posted, yet I couldn't find the answer after some searches.
I have something like:
select
htmldb_item.checkbox(1, col_name)
from...
What I need is to have is the the heading of the checkbox column same as what the wizard does. I mean you can 'check all' with that. If I put a string after the right parentheses, I got that string rendered as the name of the checkbox column, which was not I want.
I couldn't find the answer from the document, neither from the how-to.
Thanks in advance.

If this is not what you want I don't understand exactly what it is that you're attempting. Perhaps some elucidation would be in order?

I get an error when starting firefox on several user profiles: the bookmarks and history are not functional something about the file being in use.

Windows Server 2008 R2, Windows 7 workstations, the appdata folder is redirected to a network share at \\server\profiles and several users are unable to use bookmarks getting an error about the file being in use. I'm wondering if maybe my antivirus (Trend Micro) or my backups (Symantec) might be locking up the places.sqlite for these users? Though I don't understand why it would be for some users and not others. I can't be the first one and I'm not coming up with anything searching google endlessly. Anybody else run into this?

hello, yes this is likely caused by an external program locking access to the bookmarks/history database. you could try renaming the file in question & see if it is working when it is regenerated, this will clear bookmarks and the history though, so keep a backup...

Question about the function module (RFC_READ_TABLE)

Dear everyone
Could I ask you a question about the function module (RFC_READ_TABLE)?
I was asked if it's possible to create a report which compares the data between different SAP systems (both production systems).
Now, the easiest way would be to use the function module (RFC_READ_TABLE) within a SAP infoset query (SQ01 type query).
But I heard the rumor that using the function module (RFC_READ_TABLE) is not advisable due to the security reason.
However, I am not exactly sure what sort of security problems this function module can possibly have...
Would you help me on this?
I also would like to know if using "remote enabled module" type function module can always overcome this possible security issue.
Or, are there any points that I need to be careful about even when I use "remote enabled module" function module?
Thank you very much in advance.
Takashi

Dear Fred-san
Thank you very much for your support on this.
But, may I double check about what you mentioned above?
So, what you were mentioning was that if some user executes the query with
the function module (RFC_READ_TABLE), under the following conditions, he can access to
the HR data even when he does not have the authorizations for HR transactions?
<Conditions>
1. the user has the authorization for HR database tables themselves
2. RFC_READ_TABLE is called to retrieve the data from HR database
<example>
Data: LF_HR_TABLE like DD02L-TABNAME value 'PA0000'.
CALL FUNCTION 'RFC_READ_TABLE'
   EXPORTING
    query_table                = LF_HR_TABLE
TABLES
   OPTIONS                    =
   fields                     =
   data                       =    .
But then, as long as we call this function module for a non-critical tables such as
VBAP (sales order) or EKKO (purchase order) within our query, it wouldn't seem to be
so security risk to use RFC_READ_TABLE...
Besides, each query (infoset query) has got the concept of user groups, which limits
the access to the queries within the user group.
※If someone does not belong to the user group, he cannot execute the queries within that
   user group, etc
So, my feeling is that even infoset queries does have authorization concept...
Would you give me your thought on this?
I also thank you for your information for SCU0.
That is an interesting transaction
Kind regards,
Takashi

Some question about the renegotiation function in SRM Contract (GOA)

Hi All Expert,
We are on SRM 5/4.6, there is a question about the renegotiation function in SRM GOA.
Can we renegotiate the price for some parts in the GOA items with this function ( e.g. Only renegotiate one item in the contract) ?
Will the item price updated automatically after the renegotiation?
Many thanks in advance!!!
Wendrin

Hi Sanjeev,
Many thanks for your help.
One more question, if I add a new item when we renegotiation, will it be transfered to contract and create a new item after that?
Thanks and best regards

A question about the impact of SQL*PLUS SERVEROUTPUT option on v$sql

Hello everybody,
SQL> SELECT * FROM v$version;

Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
PL/SQL Release 11.2.0.1.0 - Production
CORE    11.2.0.1.0 Production
TNS for Linux: Version 11.2.0.1.0 - Production
NLSRTL Version 11.2.0.1.0 - Production
SQL>
OS : Fedora Core 17 (X86_64) Kernel 3.6.6-1.fc17.x86_64I would like to ask a question about the SQL*Plus SET SERVEROUTPUT ON/OFF option and its impact on queries on views such as v$sql and v$session. Here is the problem
Actually I define three variables in SQL*Plus in order to store sid, serial# and prev_sql_id columns from v$session in order to be able to use them later, several times in different other queries, while I'm still working in the current session.
So, here is how I proceed
SET SERVEROUTPUT ON; -- I often activate this option as the first line of almost all of my SQL-PL/SQL script files
SET SQLBLANKLINES ON;
VARIABLE mysid NUMBER
VARIABLE myserial# NUMBER;
VARIABLE saved_sql_id VARCHAR2(13);
-- So first I store sid and serial# for the current session
BEGIN
    SELECT sid, serial# INTO :mysid, :myserial#
    FROM v$session
    WHERE audsid = SYS_CONTEXT('UserEnv', 'SessionId');
END;
PL/SQL procedure successfully completed.
-- Just check to see the result
SQL> SELECT :mysid, :myserial# FROM DUAL;
    :MYSID :MYSERIAL#
       129   1067
SQL> Now, let's say that I want to run the following query as the last SQL statement run within my current session
SELECT * FROM employees WHERE salary >= 2800 AND ROWNUM <= 10;According to Oracle® Database Reference 11g Release 2 (11.2) description for v$session
http://docs.oracle.com/cd/E11882_01/server.112/e25513/dynviews_3016.htm#REFRN30223]
the column prev_sql_id includes the sql_id of the last sql statement executed for the given sid and serial# which in the case of my example, it will be the above mentioned SELECT query on the employees table. As a result, right after the SELECT statement on the employees table I run the following
BEGIN
    SELECT prev_sql_id INTO :saved_sql_id
    FROM v$session
    WHERE sid = :mysid AND serial# = :myserial#;
END;
PL/SQL procedure successfully completed.
SQL> SELECT :saved_sql_id FROM DUAL;
:SAVED_SQL_ID
9babjv8yq8ru3
SQL> Having the value of sql_id, I'm supposed to find all information about cursor(s) for my SELECT statement and also its sql_text value in v$sql. Yet here is what I get when I query v$sql upon the stored sql_id
SELECT child_number, sql_id, sql_text
FROM v$sql
WHERE sql_id = :saved_sql_id;
CHILD_NUMBER   SQL_ID          SQL_TEXT
0              9babjv8yq8ru3    BEGIN DBMS_OUTPUT.GET_LINES(:LINES, :NUMLINES); END;Therefore instead of
SELECT * FROM employees WHERE salary >= 2800 AND ROWNUM <= 10;for the value of sql_text I get the following value
BEGIN DBMS_OUTPUT.GET_LINES(:LINES, :NUMLINES);Which is not of course what I was expecting to find in v$sql for the given sql_id.
After a bit googling I found the following thread on the OTN forum where it had been suggested (well I think maybe not exactly for the same problem) to turn off SERVEROUTPUT.
Problem with dbms_xplan.display_cursor
This was precisely what I did
SET SERVEROUTPUT OFFafter that I repeated the whole procedure and this time everything worked pretty well as expected. I checked SQL*Plus documentation for SERVEROUTPUT
and also v$session page, yet I didn't find anything indicating that SERVEROUTPUT should be switched off whenever views such as v$sql, v$session
are queired. I don't really understand the link in terms of impact that one can have on the other or better to say rather, why there is an impact
Could anyone kindly make some clarification?
thanks in advance,

Hi Dariyoosh,
SET SERVEROUTPUT ON has the effect of executing dbms_output.get_lines after each and every statement. Not only related to system view.
Here below what Tom Kyte is explaining in this page:
Now, sqlplus sees this functionality and says "hey, would not it be nice for me to dump this buffer to screen for the user?". So, they added the SQLPlus command "set serveroutput on" which does two things
1) it tells SQLPLUS you would like it <b>to execute dbms_output.get_lines after each and every statement</b>. You would like it to do this network rounding after each call. You would like this extra overhead to take place (think of an install script with hundreds/thousands of statements to be executed -- perhaps, just perhaps you don't want this extra call after every call)
2) SQLPLUS automatically calls the dbms_output API "enable" to turn on the buffering that happens in the package.Regards.

Question about the programming of a legend

Hello everybody,
I have a question about the programming of a waveform's legend. I
already asked here in this forum about the legend programming (03)
months ago.
I went satisfied but I ve just noticed that this code
(See Code old_legend_test.llb with main.vi as main function) operates a
little different from my expectances.
Therefore I have a new question and I want to know if it
is possible by labview programming to plot and show, on a waveform
chart, a signal with activ plot superior to zero (0) without to be
obliged to plot and show a signal with activ plot equal to zero (0) or
inferior to the desired activ plot.
I give you an example
of what I m meaning. I have by example 4 signals (Signal 0, 1, 2 and 3)
and each signal corresponds respectively to a channel (Chan1, Chan2,
Chan3, Chan4). I want to control the legend (activ plot, plot name and
plot color) programmatically. Is it possible with labview to plot signal
1 or 2 or 3 or (1, 3) or (2,3) or (1,2,3) or other possible combination
without to active the signal with the corresponding activ plot zero
(0)?
Let see the labview attached data
(new_legend_test.llb with main.vi as main function). When I try to
control the input selected values again I get them back but I don't
understand why they have no effect on the legend of my waveform chart.
Could somebody explain me what I m doing wrong or show me how to get a
correct legend with desired plots? Thank by advance for your assistance.
N.B.
The
both attached data are saved with labview 2009.
Sincerly,PrinceJack

Hi
princejack,
Thanks for
posting on National Instruments forum.
The behavior
you have is completely normal. You can control the number of row displayed in
the legend and this rows are linked to the data you send to your graph. Thus,
if you have 3 arrays of data, let say chan1, chan2 and chan3, you can choose
which data you want to display in your graph using the property node (Active
plot and visible). But for the legend as you send 3 plots there is an array of
the plot name [chan1, chan2, chan3] and you can display 0, 1, 2 or 3 rows of
this array but you cannot control the order in this array! So, to be able to
change this array you have to only send data you need to you graph. I'm not
sure my explanations are clear so I have implemented a simple example doing
that.

Question about the "iPod radio remote"

I assume the "radio remote" is the same for every country and is under software control. I want to buy in Canada but use in UK and Canada.
Has anyone got one and seen the RDS work, in the UK almost every FM channel is RDS. Do they have RDS in Canada (Toronto) can anyone confirm?
And of course it says FM so this again I assume no AM, not that I need AM it was just an interest in if it could do it.
What happens about headphones, you can plug a pair into the remote, can you still plug into the bottom of the iPod or does the remote connector get in the way.
What is the story with "line out" I use this all the time as I amp my headphones. So I assume you cant use line out? or is the remote a line out also.
And I assume the remote cable and you headphones act as the aerial, how is the quality? Is it any good indoors, some little FM radios I have used drop to mono indoors. Does this Apple one frop to mono if the signal is weak?
Someone that has one can perhaps answer
Cheers
Ray

I can at least answer some of the questions.
The RDS function on this radio/remote is poor in the
UK. You have to set the radio function on the iPod
to "Europe" and when you do this RDS info is not
displayed on almost all radio stations such as
Virgin, XFM, Capital, GLR, etc. It does display on
Radio 2 however. At least, this is my finding. So
it's unpredictable at best. Setting the radio to
"USA" on the iPod increases the likelihood of getting
the RDS to display, but the downside is that you can
then only tune the radio in increments of 2mhz which
is a bit awkward if your looking for 89.1mhz!
There are three settings for the radio which you
choose via the iPod. They are USA/Europe/Japan. No
setting for Canada, although I'm sure you will still
be able to use it over there as I can still use mine
here in the UK even if it's set to USA.
No, there is no AM radio.
You can plug headphones into the remote or the
headphone jack on the iPod, or both at the same time.
I'm not sure I understand your question about the
bottom of the iPod. The radio plugs into the iPod
via the dock connector.
There is no 'line out' on the iPod. If you mean the
one on the dock, then no you can't use it as you
cannot place the iPod into the dock whilst the
radio/remote is connected as they use the same
connector.
Yes the cable of the remote acts as the aerial.
Reception is surprisingly good where I am, but it
will of course depend on where you use it. I've
used it indoors without any drop in signal or it
dropping to mono.
Lastly, you need to update the software for both the
nano or the 5th generation for the radio to work
(after you do this a radio function appears in the
menu), and some users have found that doing this
screws up the iPod. I have mine working on both the
nano and the 5th gen without any problems.
There is a review of the radio/remote here. I like
mine and consider it a worthwhile accessory, but of
course there will be those who disagree.
iPod
Radio/Remote Review.
Thank you for the reply.
Think your right USA or Europe will work in Canada.
Yes I mean the line out via the dock, I just wondered if the remote become a line out socket (I also use a pocket dock for line out for headphone amp as I use a pair of Sennheiser HD600 with my ipod) but of course that is silly becasue you have a volume control on the remote and line out is normaly fixed.
Based on your views I shall get one in March when in Toronto
Cheers

Questions about the content of download meeting recording .zip file

I tried posting this on the resurrected Connect forum, but my Adobe ID wasn't recognized there....
Concerning the files that are included in the .zip file of the meeting recording that can be downloaded:
1) Is there any documentation describing the files and their contents (i.e. what each file represents, what each XML element and attribute in those files represent)
2) Are there any files that capture mouse movement on a shared desktop?
Thank you!

Hi Sean,
Regarding your first post:
Thanks Jorma! I don't have access to an FMS build at the moment but I'm quite certain it's there. As for contacting Jaydeep, I am 90% sure he authorized us to broadcast his email on here if folks had questions about the tool, but, in the case that I'm wrong and he didn't - I'm going to double-check first.
Regarding your most recent post..
"To be clear, the most critical goal I'm trying to accomplish is to create an automated process that will download the recording meeting at its highest quality in a consistent and reliable manner".
I personally believe this is possible; unfortunately, I haven't seen it done yet. If your recording contains:
- audio
- a camera feed
- screensharing
Then I think you might be able to get this going. If it contains shared content, like a shared PPT, this gets trickier.
"To do this, of course, I have to reproduce some of the functionality that Connect provides, starting and combining video and audio streams according to the instructions in the control files."
Exactly right. If your recording didn't contain shared content, then all you've got on your hands are a bunch of audio/video files that you could edit together as you wanted with your favourite video editing tool. If it contains shared content, here's (at a high level) what's happening.
For shared PPTs or FTContent files:
First (for version 9 recordings only), Connect reads the information on the Shared Content's location and SCO within mainstream and indexstream and validates it before loading it. I don't recall this happening to the same extent with version 8 or earlier, but maybe it was. Now, if the content is validated (ie. Connect can find it) the share pod will display as black, if it doesn't, you get an empty pod with an message like "No content is being shared" or something like that.
Connect then looks at the actual FTContent file, and loads the content that is to be shared using the file path and sco ID listed in here. It's important to note that the SCO ID and file path in here will likely not be the same as the original file you uploaded to your room, it's a new SCO id (I believe SCOs of this type are called referenced scos) and new path.
Now...if I was going to build some sort of player which would play all these files in one screen to make a recording...I might not want to use Connect's code here. If you know the file path to the shared content (from FTContent), you could easily view it with the content URL (conveniently also in FtContent). I'm not a coder, but I'm envisioning something like Presenter's GUI where you've got the presentation's content in the main area, and a video file (if there is one) playing back on the side.
Anyways, food for thought if you want to try to go about this. Connect recordings are incredibly complex and they come with a big learning curve, but if you can make sense of them the knowledge is quite valuable.

Question about the order to creating Account, Contact, Contact Role

Hi, my friends,
I have some questions about the order of creating Account, Contact, Contact Role, etc in Web Service 1.0. I could create them in the following case:
1. Insert Contact object and get contactId (now new contact exists in CRMOD)
2. Insert Account object with Contact Role child associated with contactId
My questions are:
1. Do we have the following order? Insert new Account with new Contact child and Contact Role child (Contact is new and does not exist in CRMOD).
2. Looks like system need accountId, contactId, etc to make the objects relationship. Is there other field having the same function?
Thanks
Ray

Hi Ray,
In response to your questions:
1. Do we have the following order? Insert new Account with new Contact child and Contact Role child (Contact is new and does not exist in CRMOD).No. Both the Account and Contact must already exist. The Role value is an attribute on the Account Contact relationship, this relationship must exist in order to assign a role value to it. This is consistent with the behaviour of the UI, when you press the New button on the Contact child applet, you are taken to the Contact New page where you can create a Contact record. Once you save, the relationship is created but you cannot assign a role value unless you click the Edit Roles link next to the new Contact.
2. Looks like system need accountId, contactId, etc to make the objects relationship. Is there other field having the same function?Correct, the system needs to know which Account/Contact pair is being assigned a role value. To do this the Account and Contact values must be uniquely identified using the Id values for each.
I hope this helps.
Thanks,
Sean

Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. (In Library Manager it's the FIle -> Rebuild command)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

Where do I find the NI-DAQ function list for a specific card.

I trying to find a reference where I look up a card ID and it lists the NI-DAQ functions that work FOR THAT CARD ONLY!
Example: The PXI-4472 DSA card shows that it supports STC timer/counter functions (like GPCTR_Control()) when you search by card in NI-DAQ Help. But in reality, none of the functions work correctly, even though the function call doesn't return a status error.
Is there a place to find an accurate cross-reference so I don't keep programming my card thinking it's working correctly when it's not?

Hi,
Hopefully I can clear up your question. DAQmx is designed to work across all E-Series, DIO, and DSA boards with the same VIs. Traditional DAQ sometimes needs separate VIs for separate boards which can become rather confusing and thus one reason for the driver redesign.
There are some exceptions with the DSA boards though.
The 4472 uses the DAQ-STC chip just as you mentioned, but the full functionality of the counters are not available as they are with E-Series boards.
There are a few things to keep in mind.
#1) The STC has two counters, 0 and 1. If you synchronize 4472s, you will only be able to use counter 1. The driver claims counter 0 for special trigger delay operations.
#2) The 4472 counters have no physical connections to the "o
utside world." The EXT TRIG pin on the 4472, sometimes called PFI0, cannot be used to do anything with the counters. It cannot be a gate or source for the counter. The only pins you can use for gate, source, or output on the counters are the RTSI lines. This certainly limits the utility of the counters.
#3) Because so few customers have expressed a need for it, we have removed DSA counter access in DAQmx. If you program the 4472 (or 4461) in DAQmx, the DAQ-STC counters will not be available at all.
The DAQ-STC was included on the 4472 for some timing and triggering functionality aside from the counters (similiar to some of the jobs it performs on the E series cards). The counters are really an afterthought that came along with the chip.... they are not at all the primary reason for the STC being there.
Hope this helps!
Let me know if you have any other questions.

A few questions about the ka790gx and dka790gx

i have a few questions about the ka790gx and dka790gx , how much better is the dka790gx compaired to the ka790gx ? . how much difference does the ACC function make to overclocking etc , i plan on getting a phenom II 940BE or 720BE . i already have the ka790gx so would it be worth building another system using the dka790gx mobo , or should i keep what i already have and just change the cpu ?

It's largely irrelevant what other boards had VRM issues other than the KA790GX - the fact is it died at stock settings. Since there is little cost difference between the more robust DKA790GX (or Platinum if you really need 1394) why bother with the proven weakling? There are other examples around of the KA not having a robust power section. There's no way I would use even a 95W TDP CPU in the KA and absolutely not O/C.....!
As for the credentials of Custom PC, I have generally found their reviews accurate and balanced, and echo my own findings where applicable. If a little too infrequent.
The fact that the KA has such a huge VRM heatsink leads me to my other comments on the Forum, particularly regarding the "fudge" aspect:
"""Henry is spot on - the notion that adding a heatsink to the top of the D2PAK or whatever MOSFETS is effective is virtually worthless. The device's die thermal junction is the tab on the device back - which is always against the PCB pad. The majority of heat is therefore dissipated in to the board, and the fact that the epoxy plastic encapsulation gets hot is simply due to the inability of the heat to be conducted away from the device die via the tab. Not sure when Epoxy become an effective conductor of heat.... Good practice is to increase the size of the PCB pad (or "land" in American) such that the enlarged PCB copper area acts as an adequate heatsink. This is still not as effective as clamping a power device tab to an actual piece of ali or copper, but since the devices used are SMD devices, this is not possible. However, the surface area required to provide sufficient PCB copper area to act as a heatsink for several devices isn't available in the current motherboard layouts. Where industrial SBC designs differ in this respect is to place the VRM MOSFETs on the back of the PCB on very enlarged PCB pads - where real estate for components is not an issue.
Gigabyte's UD3 2oz copper mainboards sound like a good idea, on the face of it. However, without knowing how they have connected the device tabs to where and what remains a mystery. I suspect it is more hype than solution, although there will be some positive effect. From an electrical perspective, having lower resistance connecting whatever to whatever (probably just a 0V plane) is no bad thing.
The way the likes of ASUS sort of get round the problem is to increase the sheer number of MOSFET devices and effectively spread the heat dissipation over a larger physical area. This works to a degree, there is the same amount of heat being dissipated, but over several more square inches. The other advantage of this is that each leg of the VRM circuit passes less current and therefore localised heat is reduced. Remember that as well as absolute peak operating temperature causing reduced component life, thermal cycling stresses the mechanical aspects of components (die wire bonds for example) as well as the solder joints on the board. Keeping components at a relatively constant temperature, even if this is high (but within operating temperature limits), is a means of promoting longevity.
For myself, the first thing I do with a seperate VRM heatsink is take it off and use a quiet fan to blow air on to the VRM area of the PCB - this is where the heat is. This has the added benefit of actively cooling the inductors and capacitors too....
Cooling the epoxy component body is a fudge. If the epoxy (and thus any heatsink plonked on top of it) is running at 60C, the component die is way above that.....
It's better than nothing, but only just."""
