I got an interesting question a while ago: should an application terminate (anonymous) threads or not?
Started.WaitFor might not return (which you cannot get around this because all overloads of the CheckThreadError are non-virtual)A problem is that a thread might not execute unless you call WaitFor before Terminate is called. The reason is that the internal function ThreadProc does not start Execute if the thread is already terminated.
The
ThreadProcin theSystem.Classesunit is an ideal place to set breakpoints in order to see which threads might start.Other useful places to set breakpoints:
TAnonymousThread.ExecuteTExternalThread.Execute
Execute not being called by ThreadProc is a bug, but it is not documented because QC is gone (taking the below entry with it), it is not in QP and the docwiki never got updated.
Given QC has so much information, I am still baffled that Embarcadero took it down.
Sergey Kasandrov (a.k.a. serg or sergworks) wrote in [WayBack] Sleep sort and TThread corner case | The Programming Works about this bug and refers to WayBack: QualityCentral 35451 – TThread implementation doesn’t guarantee that thread’s Execute method will be called at all .
The really bad thing are the WayBack: QualityCentral Resolution Entries for Report #35451 Resolution “As Designed” implying the design is wrong.
In his post, sergworks implemented the Sleep sorting in Delphi. Related:

Note that application shutdown is a much debated topic. Best is to do as little cleanup as possible: your process is going to terminate soon anyway. No need to close handles or free memory: Windows will do that for you anyway. See for instance:

[WayBack] The Myth of Advanced TDD
People frequently ask me for “advanced TDD”. I have good news and bad news.
if you think you need to to “advanced TDD”, then you don’t do TDD.
If TDD hurts, then you need to improve your design or code. It’s like going to the gym: it’s not the exercise that causes the hurt, but the lack of physical condition.

Since each Windows version, Microsoft hides the way to first enable, then configure IIS Logging in a different place: [WayBack] Enabling IIS log files on Windows 7.
That should provide me some guidance on how to find it back when it is not displayed at all.
Related:
To enable logging, use the following syntax:
appcmd set config /section:httpLogging /dontLog:False
To disable logging, use the following syntax:
appcmd set config /section:httpLogging /dontLog:True
Note
When you use Appcmd.exe to configure the <httpLogging> element at the global level in IIS 7, you must specify /commit:WEBROOT in the command so that configuration changes are made to the root Web.config file instead of ApplicationHost.config.

Since I always forget this: [WayBack] Exceljet: Get day name from date
If you need to get the day name (i.e. Monday, Tuesday, etc.) from a date, there are several options depending on your needs.
Basically there are four ways go get the day of the week; the first three are readable, but when ordered, they are ordered alphabetically. The last one is numeric.
Combining the numeric with the text is easier in for instance Pivot Legend Fields (Series).
So here they go (based on the above link), assuming that B4 contains a timestamp:
=WEEKDAY(B4) gives you the numeric weekday (starting with Sunday=1 to Saturday=7) which allows sorting in a meaningful order=TEXT(B4,"dddd") gives you the full day name of B4 in your locale=TEXT(B4,"ddd") gives you the shortened day name of B4 in your locale=CHOOSE(WEEKDAY(B4),"Sun","Mon","Tue","Wed","Thu","Fri","Sat") gives you a name of your liking from a series of 7 textsNote that depending on your locale, these formulas might actually need a semicolon:
=WEEKDAY(B4)=TEXT(B4;"dddd")=TEXT(B4;"ddd")=CHOOSE(WEEKDAY(B4);"Sun";"Mon";"Tue";"Wed";"Thu";"Fri";"Sat")–jeroen

Somehow I misplaced the manuals of my Sony STR-DE205 receiver, including the Operating Instructions.
Sony still makes receivers
I did find [WayBack] Sony STR-DE205 – Manual – AM/FM Stereo Receiver – HiFi Engine which has a Service Manual. It has no operating instructions though.
Luckily, the STR-DE205 is very similar to the Sony STR-DE305, which I found using sony str de205 filetype:pdf operating instructions and having an Operating Instructions copy at [WayBack] pdf.crse.com/manuals/3810995221.pdf.
In fact, all the pictures in that manual look remarkably similar to the STR-DE205, except for one: the remote control:
It has one extra button POWER, which the STR-DE205 lacks, which likely means the STR-DE305 can be powered on remotely (like my trusty Sony MHC-3000 mini set that is slightly older).
Anyway, programming is easy as long as you know you need to press one of the NUMERIC BUTTONS in step 5:
Getting the text out of the PDF was a bit of a pain, as even though it renders, DRM tried to prohibit copying.
Luckily there is a
pdftohtmlwith a-nodrmfeature in Poppler (software) – Wikipedia (unlike the Xpdf – Wikipedia it forked from that does not have this switch) which I got based on these links:
Some more images are below after some Sony STR-DE205 videos.
